Got call from extremely angry customer, our product is shit and doesn't work. At all. Important customer so I went to visit.
He had the perfect setup, our product to the left, our competitor's to the right.
He connected the Ethernet cable to their product, it worked. He plugged it out and connected to ours... Nothing. Shit.
I started to debug on the premises, took logs, everything. It seemed like our product didn't receive any data at all. What the fuck? Tried everything, debugged low level, still nothing. Sweating as hell.
After two hours I got a strange feeling. So I swapped place, our product to the right, competitor's to the left. Now OUR product worked, competitor's zilch.
THE FUCKING ETHERNET CABLE HAD A GLITCH. IF YOU BENT IT TO THE RIGHT IT WORKED, IF YOU BENT IT TO THE LEFT IT WAS BROKEN.
I had never seen a customer be this embarrassed in my life. He apologized to me, my boss, his boss, the Queen, everyone.
We got the contract.19
"WiFi is better than Ethernet because the air is bigger so it can hold more internet."
Yes, and horse-drawn carriages are better than cars because they have bigger wheels.13

Hello everyone, found this place recently, decided to bore you with one (or many) Navy story... tech Navy story. I'll start from the end.
Little backstory: I've deployed a simple domain setup on the ship I served, nothing fancy, a server, a switch, 10 computers, all Windows (details on that at another rant). I enter the ship Monday morning, and the XO tells me that he can't access his online folders.
OK, I say, I'll get to it. I fire up my laptop, try to RDP to the server (I know, I know, burn me at the stake later) no connection. WTF? Is the service down? I try pinging. No luck. I tried pinging the switch. OK. Looking at the switch admin panel, I see the server's port is dead. "OK, probably the cable." (we have old ethernet cables)
So, I drag my ass over to the server (same room with ship comms) with the cable tester to confirm that. What do I see?
The IMBECILES had pulled the plug from the server so that they could charge their mobile phones. I literally slammed my head against the door (calming exercise in case of spontaneous murder impulses - the things you learn at the Academy). My CO was nearby, and lucky for the guys, he heard me yell at them, while throwing mobiles and chargers around.
"But we thought it was OK, we just wanted to charge our-"
I kid you not, I reached for the firefighter's axe.
My CO grabbed me by the collar and dragged me to his room. I explained to him (between two cigarettes) that we MUST get a UPS and a server cabinet (budget constraints in the military are something that will give you people nightmares, trust me). I carefully explained to him that unless we got those, nothing would prevent the next moron from destroying confidential data and me from murdering him.
I plugged in and booted the server, after installing a multi socket extension. Two days after, surprise surprise, the server was off again. That was the first time I opened the door to the CO's room with a low kick. I must have looked like a psycho on drugs, he gave approval for the purchase in twenty seconds flat.
After that, I installed the UPS and the cabinet. Everything went inside, from the UPS to the very plugs. Just a locked box with cables coming out.
One of the guys came to my room, and asked if I could unlock the cabinet so that they could plug a "device" they needed.
I actually reached for my folding knife.
Disclaimer: The story above is TRUE. Even the almost violent parts.24
My girlfriends mom asked whether I could fix her coworkers laptop. She claimed that it had viruses installed and laptop is laggy..
So... I got that laptop just now, got home and turned it on. It doesn't have WiFi drivers installed and I do not have any free Ethernet cable right now.
About the lags... Well you won't believe how many custom tool bars and security programs there were. McAffe, AVG, ESET and some Russian made firewall which asks for license key every 5mins.
And she asked me to reinstall windows and keep every file of hers, and she didn't bother to point which files of 300gb of photos/videos/docs are worth keeping and which are not.. HDD is 300GB :A fuck me
P. S. Since it's my first rant I can say ranting helps a lot to calm down25
Someone on my Facebook was boasting that he now has 1Gb internet speed.
Turns out he bought a 1Gbit ethernet card for his PC and thought that alone would raise his broadband speed..10
Navy story time, and this one is lengthy.
As a Lieutenant Jr. I served for a year on a large (>100m) ship, with the duties of assistant navigation officer, and of course, unofficial computer guy. When I first entered the ship (carrying my trusty laptop), I had to wait for 2 hours at the officer's wardroom... where I noticed an ethernet plug. After 15 minutes of waiting, I got bored. Like, really bored. What on TCP/IP could possibly go wrong?
So, scanning the network it is. Besides the usual security holes I came to expect in ""military secure networks"" (Windows XP SP2 unpatched and Windows 2003 Servers, also unpatched) I came along a variety of interesting computers with interesting things... that I cannot name. The aggressive scan also crashed the SMB service on the server causing no end of cute reactions, until I restarted it remotely.
But me and my big mouth... I actually talked about it with the ship's CO and the electronics officer, and promptly got the unofficial duty of computer guy, aka helldesk, technical support and I-try-to-explain-you-that-it-is-impossible-given-my-resources guy. I seriously think that this was their punishment for me messing around. At one time I received a call, that a certain PC was disconnected. I repeatedly told them to look if the ethernet cable was on. "Yes, of course it's on, I am not an idiot." (yea, right)
So I went to that room, 4 decks down and 3 sections aft. Just to push in the half-popped out ethernet jack. I would swear it was on purpose, but reality showed me I was wrong, oh so dead wrong.
For the full year of my commission, I kept pestering the CO to assign me with an assistant to teach them, and to give approval for some serious upgrades, patching and documenting. No good.
I set up some little things to get them interested, like some NMEA relays and installed navigation software on certain computers, re-enabled the server's webmail and patched the server itself, tried to clean the malware (aka. Sisyphus' rock), and tried to enforce a security policy. I also tried to convince the CO to install a document management system, to his utter horror and refusal (he was the hard copy type, as were most officers in the ship). I gave up on almost all besides the assistant thing, because I knew that once I left, everything would go to the high-entropy status of carrying papers around, but the CO kept telling me that would be unnecessary.
"You'll always be our man, you'll fix it (sic)".
What could go wrong?
I got my transfer with 1 week's notice. Panic struck. The CO was... well, he was less shocked than I expected, but still shocked (I learned later that he knew beforehand, but decided not to tell anybody anything). So came the most rediculous request of all:
To put down, within 1 A4 sheet, and in simple instructions, the things one had to do in order to fulfil the duties of the computer guy.
I. SHIT. YOU. NOT.
"What I can do is write: 'Please read the following:', followed by the list of books one must read in order to get some introductory understanding of network and server management, with most accompanying skills."
I was so glad I got out of that hellhole.6
My router is behind my bed so I have an Ethernet cable running through the house from my computer. When I'm drunk I can just follow the cable to bed. it works out pretty well.5
Went to a shop to buy bubble plastic envelopes (gotta send something carefully).
Walked out with a new Bluetooth music headset, couple of charging cables, Ethernet cable and a music input splitter and also those envelopes.
Why am I like this 😓19
This facts are killing me
"During his own Google interview, Jeff Dean was asked the implications if P=NP were true. He said, "P = 0 or N = 1." Then, before the interviewer had even finished laughing, Jeff examined Google’s public certificate and wrote the private key on the whiteboard."

Pop (onomatopoeia) : The sound your managed gigabit switch makes when you accidentally plug it into the power supply of your 48-volt power-over-Ethernet switch instead of its usual 9-volt supply.14
*builds a DIY 3.5mm audio wire out of metal jacks, 28 AWG electrical wire, and Ethernet wire coat as a sleeve*
*measures its resistance by doing 4 wire measurement*
(4 wire measurement explanation => https://youtu.be/L9q5vwCESEQ?t=260)
Turns out to be 800 milliohms for this wire.. well that's crappy. At such a low voltage like what the sound card puts out (30mV peak-to-peak at best) that's gonna heavily attenuate the sound, no?
*measures another audio wire that I bought a while ago with the same method*
3.2 fucking ohms, and my test at 1A significantly heated up the wire too. Turns out that this DIY contraption is 4 times better than the commercial ones out there... Sometimes you really have to dial down to what common standards you're building your own stuff against. And it's relatively easy to build too.. awesome! :)
Well, all I can say is that I'm satisfied ^^11
One comment from @Fast-Nop made me remember something I had promised myself not to. Specifically the USB thing.
So there I was, Lieutenant Jr at a warship (not the one my previous rants refer to), my main duties as navigation officer, and secondary (and unofficial) tech support and all-around "computer guy".
Those of you who don't know what horrors this demonic brand pertains to, I envy you. But I digress. In the ship, we had Ethernet cabling and switches, but no DHCP, no server, not a thing. My proposition was shot down by the CO within 2 minutes. Yet, we had a curious "network". As my fellow... colleagues had invented, we had something akin to token ring, but instead of tokens, we had low-rank personnel running around with USB sticks, and as for "rings", well, anyone could snatch up a USB-carrier and load his data and instructions to the "token". What on earth could go wrong with that system?
We got 1 USB infected with a malware from a nearby ship - I still don't know how. Said malware did the following observable actions(yes, I did some malware analysis - As I said before, I am not paid enough):
- Move the contents on any writeable media to a folder with empty (or space) name on that medium. Windows didn't show that folder, so it became "invisible" - linux/mac showed it just fine
- It created a shortcut on the root folder of said medium, right to the malware. Executing the shortcut executed the malware and opened a new window with the "hidden" folder.
Childishly simple, right? If only you knew. If only you knew the horrors, the loss of faith in humanity (which is really bad when you have access to munitions, explosives and heavy weaponry).
People executed the malware ON PURPOSE. Some actually DISABLED their AV to "access their files". I ran amok for an entire WEEK to try to keep this contained. But... I underestimated the USB-token-ring-whatever protocol's speed and the strength of a user's stupidity. PCs that I cleaned got infected AGAIN within HOURS.
I had to address the CO to order total shutdown, USB and PC turnover to me. I spent the most fun weekend cleaning 20-30 PCs and 9 USBs. What fun!
What fun, morons. Now I'll have nightmares of those days again.9
For anyone that goes to a TVDSB school in Canada, you can gain access to admin account by following the steps:
1. Enter your username
2. Put your hand on the Ethernet cable (do not pull yet)
3. Enter your password
4. Press enter
5. Wait 1.5-3 seconds
6.unplug the Ethernet cable
8. Plug in the Ethernet cable when you are at the desktop screen and all app icons have loaded.
9.enjoy full admin access!!62
In 2004 my mom decided to put Ethernet cables into the walls of our house, which is very awesome. Now i found out that the're Cat6!6
University dorm admin story:
One guy had a problem with his ethernet cable. He broke RJ45 and wanted new one, so he asked on dorms group what to do. He was pointed to admin. So he grabbed a knife, cut the cable as close to wall as he could and walked with it to the admin guy. He said that he had problem with his cable and want new RJ45, so admin applied it on the both sides. Then he asked how to plug it back to the wall :D20
After 4 months I've just realised that my internet is not running higher than 100mpbs because I bought a 100mbps Ethernet switch. -facepalm-6
What I did wrong during my home office cleaning session this morning:
- put soap on my mouse mat
- snapped my enter key
- vacuumed up my F8 key
- absent-mindedly cut my ethernet cable
- lost my zero key
- dropped my backup hard drive (data was recoverable, but I need a new drive)
- lost one of the nose pads on my glasses
- got a cocktail stick stuck in a USB port
- exploded my mouse by using the wrong type of battery
Things I did good:
A roommate said he didnt have internet on his laptop. Wifi wasnt working for him and the cable doesnt fit because he has a new ethernet port and needs another cable for that.
I told him that there is no new ethernet port or new ethernet port standard, I would have heard about it.
But he insisted that it was true.
So I grabbed the ethernet cable, pulled the clamp on his ethernet port down (as most new laptops now have) and plugged the cable in.3

4 live cds
(Ubuntu, mint, Debian, Antergos)
3 wouldn’t boot beyond splash screens or even into setup.
no fucking keyboard
No fucking wifi
No fucking trackpad
Now I’m sitting here with Antergos, with a USB keyboard, USB mouse and an ethernet cable plugged into my laptop 🤷♂️
Good news... I think I might be getting through the hard parts28
So my ethernet randomly stopped working on Arch.
At first I thought it had to do with a conflict between it and my tethered phone, so I tried removing all my connections. Still wasn't working.
Next I tried to test the driver itself and make sure it loaded on boot. It loaded, but was disconnected.
Next I decided "fuck it, I know I was just using the internet on Windows, but I'll check the ethernet cable is still plugged in anyway". It was, and it was returning the right MAC address, but still no connection.
So I try debugging the driver further. Everything seemed fine, except it would time out trying to establish a dhcp connection.
Finally I figured, maybe Microsoft tried to troll me and lock out the ethernet waking on boot. So I restart my computer, load into windows and check my ethernet driver, it seems fine. I go to disable the shutdown of the card on OS shutdown. Turns out this driver no longer has that capability.
Wait a minute!? Windows is also having connection issues!?
I look to my left.
Fuck my life...
My router was off... I must of kicked the powerboard under my desk..........2
Tried to switch to Manjaro from Ubuntu.
Everything good except ethernet not working.
3 hours wasted, updated the kernel, three network managers changed, realised that the ethernet wire was loose at the modem end.
Conversation with my older sister
Me: "open CMD and enter command"
Big sis: *enters command*
Me: "Look for Ethernet Adapter"
Her: "What?? I can't see it"
*pause 'cause I'm confused*
Her: "Wait, was I supposed to press enter?"
Please, for fucks sake people, STOP CALLING ALL FORMS OF INTERNET ACCESS WI-FI. CELLULAR ACCESS IS NOT WI-FI. FUCKING ETHERNET + FIBER OPTIC/SOME MORE COPPER CABLING/WHATEVER IS **NOT** WI-FI.12
One of the students in my department was smart and driven, but also really awkward. I had known him perhaps better than most other students, and had gleaned that he was depressed and had low self esteem.
On a few occasions he tied a noose out of an ethernet cable hanging from the ceiling and played "Pumped Up Kicks" when asked to choose a song at a party. Really strange stuff. If we had been betting on who would turn out a school shooter, I would've put my money on him.
Anyway, he graduated last year and this year I found out federal agents raided his home because he was building pipe bombs and intended to kill a bunch of people and himself. He's now doing at least 10 years in prison.4
*wrestling commentator voice*
"In this weeks episode of encoding hell:
The iiiinnnfamous UTF-8 Byte Order Mark veeeersus PHP!"
For an online shop we developed, there is currently a CSV upload feature in review by our client. Before we developed this feature, we created together with the client a very precise specification, including the file format and encoding (UTF-8).
After the first test day, the client informed us, that there were invalid characters after processing the uploaded file.
We checked the code and compared the customer's file with our template.
The file was encoded in ISO-8859-1 and NOT as specified UTF-8.
But what ever, we had to add an encoding check, thus allowing both encodings from now on.
Well well well welly welly fucking well...
Test day 2: We receive an email from said client, that the CSV is not working, again.
This time: UTF-8 encoding, but some fields had more colums with different values than specified.
We tell the customer that.
(I was about to write a nice death threat novel to them, but my boss held me back)
Testing day 3, today:
"The uploading feature is not working with our file, please fix it."
I tried to debug it, but only got misleading errors. After about 30 minutes, at 20 stacks of hatered, I finally had an idea to check the file in a hex editor:
God fucking what!?!!?!11?!1!!!?2!!
The encoding was valid UTF-8, all columns and fields were correct, but this time the file contained somthing different.
Something the world does not need.
Something nearly as wasteful as driving a monster truck in first gear from NYC to LA.
It was the UTF-8 Byte Order Mark.
3 bytes of pure hell.
The archenemy of PHP and sane people.
If the devil had sex with the ethernet port of a rusty Mac OS X Server, then 9 microseconds later a UTF-8 BOM would have been born.
OK, maybe if PHP would actually cope with these bytes of death without crashing, that would be great.3
Sure. Just unplug my ethernet cable without asking. Not like I'm trying to work or anything, right?1
Fuck you ISPs you fucking idiotic morons.
I just came to house to fix PC.
It turns out that it wasnt a simple fix at all.
The house had a good working networking done because the owner was IT guy.
The fucking ISP just disconnected that crap and run its own fucking shit because i guess they didnt understand how it was wired.
You fucking morons now i have to redesign your fucking shit because you fucked up good working internet when you could have just changed one fucking cable at router.
Sure it will be paid good to do it but damn its a lot of fucking work.
They fucked it so much that they cut cable that lead to living room half way in and i was wondering why no cable was the other end.
I had to go trough fucking spiders shit just because you fucking ISP fucked up.
Funny thing ?
They didnt fucking follow the norms.
Not even the basic fucking ones.
They twisted two fucking ethernet cables together so they could fit it trough hole and not just make the hole bigger.
Did they hear about electro-magnetism ? I guess not.
I had to run the PC to network over fucking wifi.
I gave the person my own fucking Wifi adapter until the networking is fixed in proper fucking way.
God fucking dammit !!!!!!!!!6
Coworker: Why isn't my internet working? I've checked everything, even the ethernet cable!
Me: *connects ethernet cable*
Me: Try now...
*desolders Ethernet, USB and GPIO rails from Raspberry Pi to decrease height*
(Desoldering that shit from a Pi fucking sucks btw, no idea what solder or pads they use but it's garbage)
*boots up Raspbian to see whether it still works and to set things up*
Oh shit.. I need keyboard and mouse for this :') fuck me I guess... Long live planning ahead. Does there exist a KVM over TCP/IP yet? 😅20
This is my desk right now, anyone else who really enjoys fiddling with arduino / rpi electronics stuff?
Like making a remote for the projectors in school or using an Ethernet switch and a raspberry pi to create a WiFi network :P34
2 things arrived in the mail today, still not my serial cable though. How fucking stressful, what am I gonna do!?2
Another fucking rant about my fucking goldfish brain.
At meetings, I usually note down things I need to fix, to do on the sticky note pad that comes with the OS, currently Mint.
I sat at my desk.
Looked at my notes.
Decided to properly put them as tasks on trello.
I copied all notes, planning to paste it on a trello card quickly.
Then I can just work on trello and separate into different tasks.
Ethernet said connected but websites are not showing up.
Maybe restart will fix since I haven't opened any app and started working anyway.
Trello showed up.
The website for our biggest client went down and the server went haywire. Though for this client we don’t provide any infrastructure, so we called their it partner to start figuring this out.
They started blaming us, asking is if we had upgraded the website or changed any PHP settings, which all were a firm no from us. So they told us they had competent people working on the matter.
TL;DR their people isn’t competent and I ended up fixing the issue.
Hours go by, nothing happens, client calls us and we call the it partner, nothing, they don’t understand anything. Told us they can’t find any logs etc.
So we setup a conference call with our CXO, me, another dev and a few people from the it partner.
At this point I’m just asking them if they’ve looked at this and this, no good answer, I fetch a long ethernet cable from my desk, pull it to the CXO’s office and hook up my laptop to start looking into things myself.
IT partner still can’t find anything wrong. I tail the httpd error log and see thousands upon thousands of warning messages about mysql being loaded twice, but that’s not the issue here.
Check top and see there’s 257 instances of httpd, whereas 256 is spawned by httpd, mysql is using 600% cpu and whenever I try to connect to mysql through cli it throws me a too many connections error.
I heard the IT partner talking about a ddos attack, so I asked them to pull it off the public network and only give us access through our vpn. They do that, reboot server, same problems.
Finally we get the it partner to rollback the vm to earlier last night. Everything works great, 30 min later, it crashes again. At this point I’m getting tired and frustrated, this isn’t my job, I thought they had competent people working on this.
I noticed that the db had a few corrupted tables, and ask the it partner to get a dba to look at it. No prevail.
5’o’clock is here, we decide to give the vm rollback another try, but first we go home, get some dinner and resume at 6pm. I had told them I wanted to be in on this call, and said let me try this time.
They spend ages doing the rollback, and then for some reason they have to reconfigure the network and shit. Once it booted, I told their tech to stop mysqld and httpd immediately and prevent it from start at boot.
I can now look at the logs that is leading to this issue. I noticed our debug flag was on and had generated a 30gb log file. Tail it and see it’s what I’d expect, warmings and warnings, And all other logs for mysql and apache is huge, so the drive is full. Just gotta delete it.
I quietly start apache and mysql, see the website is working fine, shut it down and just take a copy of the var/lib/mysql directory and etc directory just go have backups.
Starting to connect a few dots, but I wasn’t exactly sure if it was right. Had the full drive caused mysql to corrupt itself? Only one way to find out. Start apache and mysql back up, and just wait and see. Meanwhile I fixed that mysql being loaded twice. Some genius had put load mysql.so at the top and bottom of php ini.
While waiting on the server to crash again, I’m talking to the it support guy, who told me they haven’t updated anything on the server except security patches now and then, and they didn’t have anyone familiar with this setup. No shit, it’s running php 5.3 -.-
Website up and running 1.5 later, mission accomplished.6
So, my raspi, that controls my home automation stopped responding to all web requests, when I got home, I noticed that the wifi dongle was not lighting up, It has worked with no problems for 3 months now, so that was really weird, I plugged in the Ethernet cable, ssh'd in and ran ifup wlan0
And BOOM consoled filled with
MESSAGE FROM SYSLOGD@RASPBERRYPI
And some odd codes, no help from Google either,
Then I checked dmesg, and there were these:
Bad relocation sym offset
Mac82011: unknown symbol
At that point I got paranoid, checked my auth.log and it was FULL of failed logins, the size was well over 1Gig, and first entry was from 2 days ago....
Then some weird shit with www-data running SU
Turns out someone got in somehow ( I'm running on nonstandard port and dynamic ip, I was supposed to disable password login today, as i had enabled it temporarily)
That made me check my wifi driver , it was modified 2 mins after they got in, had a badly made rootkit but chkrootkit didn't say anything about it.
Time to setup IDS!
Any tips for where else they might have their shit in?
Oh, also, it didn't take long to bruteforce in the zombie that got in :p
And yes, it was a compromised server that was also wiped recently, so I just emailed -rf'd IT as it had tons of victim passwords
NOBODY MESSES WITH MY MACHINE AND GETS AWAY😠9
I get 20kb - 500kb - 1MB per second at my house on ethernet
School wifi - 20+MB/s
:( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :( :(32
So I just moved into a new apartment ... wait is the phone plugged to an ethernet port? ha didn't expect to have VoIP, so lucky6
TL;DR Was told to run ethernet trough ceiling with like 20 live wires and internet was down in 2 days. Yelled at "boss" and rerun it and teacher thanked us for yelling at him.
Had to run ethernet cable across school today. Me and 3 of my classmates (We are team at school which helps with tech and runs entire school internet basically) were sent to do it (ofcourse) and they told us to run it trough ceiling. OK no problem. I grab latter. WTF ? I see around 20 live wires (Isolated luckily). I ask how can i run it there since eth will not like live wires at 220V. They said to just do it.
We asked for shielded eth. Nope not getting it. Unshielded it must be.
We all knew the internet wasnt gonna be great but hey we were doing as they told us.
We did it.
Connect it and test it.
Speeds are horrific but OK fuck it.
2 days later we get call (Yes we even got a phone LOL) saying that the internet stopped working or is extremly slow. We go and test it. Indeed slow AF. Before we ran the ethernet we checked how much EM is in the ceiling. It was high but OK.
I got the idea to check again.
HOLY shit. It was literally out of scale 20 cm from the ceiling. Oh fuck.
We learnt that the backup generator charges every few days for few hours.
At the time we ran it it wasnt charging and some wires were off so it was OK but now it was charging and it was drawing a lot of power.
So after call to the idiot that told us to run it in ceiling and crash course for him about ethernet and EM and that he is an idiot we gave him 2 options. Either rerun the internet and drill like 20 holes or buy shielded cable but with that high EM (Eth is like 3cm from live wires) even shielded woudlnt help i suppose.
So we rerun it where there was almost no EM and used shielded (FTP cable) just to be sure. Oh would you look at that. Full speed as its supposed to be.
Everybody at school hates that idiot who told us to run it there and when we came to our room teacher was waiting and just told us that finally somebody said something to that idiot.
Bloody amazing feeling.9
Navy story time again. Lots of blabbering, you have been warned.
I haven't written for some time, due to paperwork bullshit that can be easily automated by even the most shitty database... no, scratch that, the simplest Excel spreadsheet with basic formulae. But I digress.
On my quest to justify myself being unproductive, I'll share with you a small story I omitted from this post:
The lunacy of the man involved, while certainly entertaining after a few years (and nautical miles) away, is certainly disturbing and most certainly true. (Late disclaimer: ALL my rants are not made-up. This is shit that truly happened before my very eyes, and while I was sober.)
After I set up some cute little stuff to try and get the CO interested, in order to give me permission (and a cut from the budget) to proceed in restructuring and upgrading the ship's net, I tried a more direct approach: connecting and setting up his work laptop with the ship's GPS, radar and AIS receptor via ethernet, and installing an ECS system so that he could monitor the ship's position, movement and targets from his office (the fat fuck couldn't be bothered to go up one deck). A day later he called me to his office.
Expecting some kind of... praise? Permission? Complaints on the font style? whatever, I entered. Oh, how I wish I had not.
I was barraged for TWO FUCKING HOURS by the CO, complaining that I was taking care of the net and PCs and neglecting the Navigation department (I was not, automation is my friend combating moronic paperwork). I would have thought it as just another failed attempt, but after TWO MINUTES from the end of the barrage:
CO:... so, my personal laptop is kind of slow, you think you can do anything about it?
What was rushing through my mind was somewhere between bipolar and multiple personality disorder, with the third option of Alzheimer's disease. I half-expected some Candid Camera crew to pop out, but no.
CO: So? Can you speed up my laptop?
ME: ............................... I don't know, sir, I have paperwork to take care of.
CO: That can wait, surely you can do something about it, you know computers.
ME: [really long pause, blood pressure rising] I'll look into it in a moment, sir.
And I never did. I told of the incident to the ship's doctor, and he expressed great worry over this, but in the end, nothing was done.
My sympathies to everyone who has to interact with non-technicians of the homo sapiens species (ironically, homo sapiens means "wise man" in latin... the irony).3
"PLEASE COME QUICKLY OUR INTERNAL NETWORK IS FUCKED!
-Uh, mam', could you describe the problem?"
Spent an hour, trying to fix this "network issue". Basic level 1 and 2 support. Can't connect using RDP on the server. No teamviewer either. Unplug, replug everything. Restart the server, the router, the switches. I knew that it was something dumb. I spent 3h on the highway.
That the fucking.
Was plugged oN THE MOTHER FUCKING ILO PORT! FUCK HP, FUCK THIS, FUCK ME BECAUSE I SHOULD'VE ASKED FOR A PHOTO.
"It's fixed, mam'. Did you touch something when it was working?
-Uh, no, I swear. Also, could you please take a look at our printer? It's not working. It was out of ink so I changed the cartridge yesterday, but today it's not working!"
The cartridge was not inserted correctly.
Then she nicely made me a coffee, thanking me for the fix and asking what the problems were.
I have a Windows machine sitting behind the TV, hooked to two controllers, set up as basically a console for the big TV. It doesn't get a lot of use, and mostly just churns out folding@home work units lately. It's connected by ethernet via a wired connection, and it has a local static IP for the sake of simplicity.
In January, Windows Update started throwing a nonspecific error and failing. After a couple weeks I decided to look up the error, and all the recommendations I found online said to make sure several critical services were running. I did, but it appeared to make no difference.
Yesterday, I finally engaged MS support. Priyank remoted into my machine and attempted all the steps I had already tried. I just let him go, so he could get through his checklist and get to the resolution steps. Well, his checklist began and ended with those steps, and he started rather insistently telling me that I had to reinstall, and that he had to do it for me. I told him no thank you, "I know how to reinstall windows, and I'll do it when I'm ready."
In his investigation though, I did notice that he opened MS Edge and tried to load Bing to search for something. But Edge had no connection. No pages would load. I didn't take any special notice of it at the time though, because of the argument I was having with him about reinstalling. And it was no great loss to me that Edge wasn't working, because that was literally the first time it'd ever been launched on that computer.
We got off the phone and I gave him top marks in the CS survey that was sent, as it appeared there was nothing he could do. It wasn't until a couple hours later that I remembered the connectivity problem. I went back and checked again. Edge couldn't load anything. Firefox, the ping command, Steam, Vivaldi, parsec and RDP all worked fine. The Windows Store couldn't connect either. That was when it occurred to me that its was likely that Windows Update was just unable to reach the internet.
As I have no problem whatsoever with MS services being unable to call home, I began trying to set up an on-demand proxy for use when I want to update, and I noticed that when I fill out the proxy details in Internet Options, or in Windows 10's more windows10-ish UI for a system proxy, the "save" button didn't respond to clicks. So I looked that problem up, and saw that it depends on a service called WinHttpAutoProxySvc, which I found itself depends on something called IP Helper, which led me to the root cause of all my issues: IP Helper now depends on the DHCP Client service, which I have explicitly disabled on non-wifi Windows installs since the '90s.
Just to see, I re-enabled DHCP Client, and boom! Everything came back on. Edge, the MS Store, and Windows Update all worked. So I updated, went through a couple reboots-- because that's the name of the game with windows update --and had a fully updated machine.
It occurred to me then that this is probably how MS sends all its spy data too, and since the things I actually use work just fine, I disabled DHCP Client again. I figure that's easier than navigating an intentionally annoying menu tree of privacy options that changes and resets with every major update.
But holy shit, microsoft! How can you hinge the entire system's OS connectivity on something that not everybody uses?9
Yeah its happening installing skyrim on linux on Lenovo miix 3-830 (baytrail-M device) yeah lets see if it will work
Btw im using usb to Ethernet adapter which is usb 2.0 so thats why that speed of internet.2
Okay you bastards ya got me: I fucking enjoy using Linux as my dev environment.
There, I SAID IT -
BUT DON'T THINK FOR A SECOND IT MEANS THAT I STOPPED HATING IT
Oh the fucking love hate relationship to fucking Linux.
"Hey, ihatecomputers! How many hours per year did you spend fixing internet connectivity issues on Windows?" you ask. Well, close to fucking 0 you goddamned imbecile. But on Linux? I don't even want to talk about it.
And what about that time when I wanted to connect my bluetooth headphones so I could listen to music while studying? Well, by the time my headphones were connected to my machine (usually a one second operation) I had no time left for, you know, actual studying. Oh my god, it's the most trivial fucking thing.
Well, at least that particular issue got solved.
Unlike that fucking Ethernet connection which has been fucking out of commission since I started using fucking Linux. Wifi works just well enough to make it not worth pouring more time into troubleshooting that shit, but just barely though because my wifi IS FUCKING DOGSHIT ON LINUX
But fuck me if it isn't it the most lean thing ever! It's the goddamned opposite of bloated. So smooth and snappy. And free as in slurred speech, or whatever. It makes me happy. When I'm not seething with rage, that is.
Yeah I guess that's it, thanks for tuning in.
My mum - "Something to do with traffic lights"
Because I told her I was designing an Ethernet traffic generator device.1
First year at university, prepared to set up multiple electronics.
rPi, arduino Ethernet shield, laptop, and desktop.
Brand new netgear switch to satisfy my internet surfing needs....
After setting up my devices, I realized none of them have internet. Hm. The feed port on my switch wasn't blinking either. So I tell the front desk, and a short 7 days later the port is back on. Yay, problem solved.
One morning I arise to see the port dark and inactive. Furious I use my laptop to share an internet connection while my actual port is "broken".
Support ticket is reopened and this time I get an email saying the port was disabled due to a security issue.
Me: what's the issue?
IT: there was more than two devices connected to the port
(OnLy TwO dEvIcEs PeR port???)
Me: oh okay I will only connect two.
The next day the port is disabled, again.
Me: can you tell me why it was disabled?
IT: a switch was detected being used, security error.
Me: how do I connect more than one device to the port without a switch???
IT: Please only connect one device.
Context: one of my dad's friends is a veterinarian and he's opening a new clinic. My dad is renovating the building and I'm supposed to handle the IT part (Ethernet cables, server, laptops etc.).
Last Monday I get a phonecall from the veterinarian (which I'll be calling boss from now on) that he plans to open the next Monday. I ask him what hardware is bought and if anything is already done. As you can probably guess, the only hardware bough are Ethernet cables (with no plugs) that my dad run under the floor half a year ago.
After a brief wtf?! I asked him what he needs. The conversation goes like this (shortened a bit):
> What do you want/need?
< Make it good
< Make it so that the network lasts for years
> Ok, but what do you want? Do you want cameras? WiFi? How many PCs and laptops? What software will you use for client/patient management?
< Yes, I want cameras. Look around and decide where would be best. Clients won't need WiF, so don't botheri. I think one pc and two laptops will be fine.
> Ok, what software do you use? What does it need on the server?
< Don't worry about that. I signed a deal for a monthly subscription. I got a special offer where if I sign it for at least a year I get 10% off.
// We had this conversation about 2 month earlier. I was against cloud software because internet here is flaky at best and if the company goes out of business he loses all client data
> Why would you do that? I told you it's a bad idea because [above comment]
< Yeah, but [his employee] convinced me. He said that with cloud he'll be able to check that stuff even from his home.
> I could've set it up so that he could do it anyway. Whatever, did you get an internet connection to the building?
< Well, I've been considering getting LTE...
> Stop. You already made one mistake. If you also get an unreliable internet you risk having to close the clinic when you lose connection due to storm.
// Here he tried to argue a bit, but I was able to convince him to not do the stupidest thing he could
< Oh, and can you make it so that when I'm here I have internet on my phone and laptop?
At this point I just wanted to smack him in the face.
Anyways, a week and a half later the clinic is still closed. Not just because half of the stuff needed arrived last Friday, but mostly because the building is not usable yet. The renovations on second and third floor haven't even started yet.
And there is still no internet connection. Last Friday I even went to a local ISP (with his permission) to get everything done and he just has to go and sign the contract. When I asked him today about it he said he still hasn't been there.1
I'm thirteen, and we have an excel unit in our computer class. When she's want to teach us something, she'd deploy her screen on ours and we couldn't do anything. It took me until the third time (yes, that long) to remember the connection was wired via Ethernet. I took the cord out and my computer was free! During the boring "lesson," I opened Code::Blocks to work on a fun side project. When she notice she wasn't connecting to my computer, she walked over to my chair and saw Code::Blocks on my screen. Then, I noticed her behind me. I quickly pressed ALT+TAB. She walked back to her chair. To this day I swear she thinks Im a hacker.11
I am sooooooooo pissed right now. So fucking done with everything.
Last evening, my secondary access point was working fine. I was in a meeting and everything was going smoothly.
When I was wrapping up everything for the day, I saw that rats have chewed the outer layer of the ethernet wire. Since nobody lives in the other room we don't care much as it is mostly empty.
So I quickly grab a tape to wrap around the chewed region (as only outer covering was impacted) and some more area around it. I re-route the wire to make sure those filthy rats don't chew it again and hang the wire on the wall.
All good. I call it a day.
Today morning, when I started the router, the fucking internet did not work. The main access point worked but this secondary didn't. So I inspect the cable and no damage done by rats.
SO WHAT THE FUCK HAPPENED NOW!!!!!
I called my ISP and they said it must be the cable issue. Cool. Let's agree that cable is damaged.
THEN WHY THE FUCK IT WORKED YESTERDAY WHEN IT WAS DAMAGED!!!
Fine. Let's boot the laptop in offline mode while the guy comes and fixes it.
Okay.. I start to work. working.. working.. BAM!!!!!!
Black screen. Laptop abruptly shuts down. Complete darkness.
WHAT THE FUCKK!! NOW WHY DOES LAPTOP HAVE TO CRASH ALL OF A SUDDEN WHEN ALL I AM RUNNING IS A FUCKING NOTEPAD!!
Cool. Let's move to primary AP and start the day as it is office time already. We'll deal with anger later during the day.
So I move back to living room, boot the laptop and start the day.
I quickly wanted to check an official application and voila.. things are progressing. Finally some positivity. But to confirm I take a screenshot and try to draft an email to support team.
FUCKING GMAIL WON'T ATTACH MY SCREENSHOT AND IS FAILING SEND A STUPID SIMPLE EMAIL!!!!!!!!
When I call the customer care agent first the number was not reachable due to country code shit doesn't work and then they didn't have information about my query.
FUCK ME IS GLORY HOLE ALREADY NOW.
It's not even noon and I am soooo done with this gloomy day.
JUST FUCK EVERYTHING.

Gotta love Linux!
Wanted to install Arch on my Rasperry PI yesterday, but don't have a cardreader on my PC. Still had an SD with a different distro (RasPlex) lying around. Popped that in, connected power and ethernet only, looked up the default SSH credentials and got to a blinking terminal on my desktop PC.
Well, how am I gonna format my microSD? Rasplex comes without fdisk, and I booted it from the only microSD slot.
Well, here we go - Extracted arch to a usb thumb drive, chrooted into it, switched microSD cards, partitioned and formatted it from the USB-Arch, installed Arch on it, chrooted from Arch to Arch (😁), set up drivers, network and ssh access, rebooted to my why-the-hell-not distro.
Fuck this raspberry piece of shit. You can’t really use it for any serious job. Its just a tinkering gizmo designed to waste your time.
I’ve tried using them for several things over the years. First was as a NAS, it was either freezing, losing the wifi/ethernet connection or causing data loss. That’s right, when all it had to do was to take the fucking file someone copies over the network and write it on an external drive.
Can’t use it to view movies either - sooner or later it becomes slow to the point where its unwatchable. Even with a 1gig video, so no HD or anything like that.
Then i tried setting it up to control the ventilation in a house. It would work for a couple days or so then hang. What the fuck, am i sposed to have another raspi to reset the first one? Then what, the 3rd for the 2nd? A centipede of raspberries? And ofc controlling the relays was always hit and miss, sometimes you had to spam the button like 20 times to be sure it flips a pin high or low.
Then i tried to set it up to control a bunch of mining rigs. Once again random fails, except this time a couple video cards died to heat. No worries, RMA, what else we can do?
Then, random small scripts to read various sensors and post a json. Put a radiator and fan on it, battery, what the fuck not. But no. Random freezing, random disconnects.
Naturally all this shit spiced up with countless hours spent on debugging: is it me? Did i trip on the wire? Was it the vibration? Or perhaps the temperature or humidity? Was pluto taking a piss because its no longer a planet? What are the logs saying? Maybe it will work if we recompile? Or maybe use another language? And what the fuck not!
Who and why the fuck came up with this shit? Is it all just another conspiracy to waste my time? Dear satan you don’t need boards and kernels and java and linux and the fuckton of idiots to waste my time, just get me a couple lesbians and some booze and you’ll never hear from me until i end up in your fucking cauldron.54
Now I will defend USB-C untill my face turns blue and my mouth turns into a thunderbolt 3 port but fuck me some people complain about the stupidest shit when it comes to adapters...
Saw someone on twitter complaining because to get an ethernet port on his MBP... Only to notice he had purchased a USB-C to USB-A just so he can plug in a USB-A to ethernet...
Now maybe I'm thinking too logical but if you wanted an ethernet port, surely you would buy a USB-C to ethernet port and not seperate things to do the same job and then complain about it?
I can justify complaining about USB-C to auxiliary to some extent but for fuck sake I swear some people just get off on complaining about self inflicted issues -,-5
Today in the tech store I asked an assistant where to find the CAT6 ethernet cables.
He said he didn't know and ended up in asking me for technical support.4
Network Security at it's best at my school.
So firstly our school has only one wifi AP in the whole building and you can only access Internet from there or their PCs which have just like the AP restricted internet with mc afee Webgateway even though they didn't even restrict shuting down computers remotely with shutdown -i.
The next stupid thing is cmd is disabled but powershell isn't and you can execute cmd commands with batch files.
But back to internet access: the proxy with Mcafee is permanently added in these PCs and you don't havs admin rights to change them.
Although this can be bypassed by basically everone because everyone knows one or two teacher accounts, its still restricted right.
So I thought I could try to get around. My first first few tries failed until I found out that they apparently have a mac adress wthitelist for their lan.
Then I just copied a mac adress of one of their ARM terminals pc and set up a raspberry pi with a mac change at startup.
Finally I got an Ip with normal DHCP and internet but port 80 was blocked in contrast to others like 443. So I set up an tcp openvpn server on port 443 elsewhere on a server to mimic ssl traffic.
Then I set up my raspberry pi to change mac, connect to this vpn at startup and provide a wifi ap with an own ip address range and internet over vpn.
As a little extra feature I also added a script for it to act as Spotify connect speaker.
So basically I now have a raspberry pi which I can plugin into power and Ethernet and an aux cable of the always-on-speakers in every room.
My own portable 10mbit/s unrestricted AP with spotify connect speaker.
Last but not least I learnt very many things about networks, vpns and so on while exploiting my schools security as a 16 year old.8
Spent the past two hours debugging why ethernet wasn't working on a newly build PC... The other end of the cable wasn't in properly1
You know what would be nice? Being able to Google anything to do with VPNs without having like 90% of the results being links to how-to-setup-VPN-client pages from every goddamn obscure commercial VPN provider in existance.
If I wanted to know how to setup a VPN client to work with Crazy Dave's House-o'-VPN-n'-Cloud-Hosting's paid-for service, I probably would have Googled for that, not general things like "openvpn ethernet bridging". Why am I getting so many commercial results? Either nobody sets up their own VPNs, or the VPN companies have SEO'd the keywords good and proper.4
Actually I feel I am prety lucky about the relationship between my yamily and me being a dev. My dad is a developer as well (in fact, he was the one who taught me most of what I know today; not as in general coding, but good and bad programming practices, tips what to do next ...) and my mom just started learning Python.
So they know prety well what it means to be a dev and have quite realistic image of what to expect.
To be fair, I am still the one who usualy fixes broken printers and replugs unplugged ethernet cables. but that is because I enjoy doing that. I take it as a challenge for myself to figure out what/how/when went something wrong. Most of the times I try to figure that even without touching the broken things.
Anyway, getting off topic.
Alltogether I don't think that they have too unrealistic expectations, but if I had to chose one, it'd be my learning capabilities. I can't learn complete java in 2 days ...1
I'm about to ditch full-time Linux.
It's the little things honestly. Display resolution goes nuts when connecting or disconnecting from external displays, Bluetooth headphones suddenly aren't found anymore. I spend hours trying to fix things but often get nowhere. I love the environment, but there's just not enough convenience that I used to get with Mac or windows. This morning, pop os that I've been using for months updated and then wifi && ethernet didn't work. So I decided maybe I would switch to Mint since it's got more support. Internet works but same Bluetooth and display problems. Idk.
Someone talk me off of this ledge.16
Today, Linux kernel 5.8 was released, here is how it runs on my new laptop.
- Realtek shit ethernet still doesn't work (no, I didn't return it, because I would have to buy at least 2 times as expensive docking station instead and it is just not worth it), but considering Realtek, it is probably not a Linux kernel issue
- Battery life while watching videos was improved pretty significantly from 6.5 hours to about 7.3 hours (1080p HEVC)
- All temperature sensors are now working correctly
- Fan is a little more silent overall, probably because of some power draw improvements
- Subjectively, the system is a little bit more responsive overall4
"This ethernet cable doesn't work because you made it too fast". ffs I had to fight for my grade that day.
So my school's wifi doesn't support my TV or something, all I know is the wifi doesn't appear as a potential connection for the TV. (Even then, when I plugged the TV into the Ethernet cable, it still gave me an error message.) Well I figured out a loophole Saturday night.
I plug the Ethernet cable into my laptop. Then activate the hotspot on my laptop. Connect to the TV through the laptop's connection. Problem solved.
Loopholes are one of the best parts of life.1
Just drove to the store to buy a 40 foot long Ethernet cord so I could directly connect my computer to the router because Visual Studio is taking too long to download...4
I'd like to give a shoutout to the best tool I ever had when I worked in hardware and had to troubleshoot ethernet. The "RLFLTWKW". (The Really Long Fly Lead That We Know Works)
My friend that I worked with long ago just dug it out of a drawer and sent me a photo so we could remember the days when trying to figure out why Mavis couldn't get on the network anymore could be resolved by our faithful friend "TRLFLTWKW". I miss you buddy. You made life so much better.
I wish I had an equivalent to you for coding.
I bought a corporate refurb HP desktop to use to replace a rpi3 in an IoT project I was working on. It came with Windows 10 on it. It has an ethernet port on it, which is what I prefer, but Windows 10 couldn't see it. So I installed Debian and everything worked perfectly, with no driver config.
Context: I (among other things) manage some servers for my students' club so I have first-hand information about anything network or server-related that happens. We basically run a big enterprise network and we allow devices to connect if a person has paid their membership and the device's MAC address (be it wireless or ethernet) is recognized by our switches/aruba controllers.
Story: So today a first complaint about "the wifi not working" came in because of Android 10 and its MAC randomization. We deal with MAC randomization on Windows laptops and PCs but I think it is disabled by default so we almost never get this type of complaint.
It took one of the other guys probably 5 minutes to figure out how to disable it... only to discover it is a per-network setting.
The actual question: If there are any network administrators here on devRant - how do you deal with this MAC filtering vs MAC randomization issue?7
Dear dongle manufacturers, I love USB-C, I think everyone does; it is the bomb... But.... But but but, please stop charging so much extra for it, I can get a USB-A to Ethernet adaptor for $12 AUD but it's going to cost me at minimum $49 AUD for the same branded dongle, even has the same internal chips... Why... Just... Why!17
hey ranteros! i like to dream and i know many of us dream of a nice machine to do anything on it, if you want to post the specs of your ideal build(s) (even a laptop, pre-built pc, space gray macbook pro... doesn't matter). and your current one.

if you read this whole thing i love you, and if you have some time to spare on a sunday you can share your dream rig and the sometimes cruel current one if you dare. you don't have to share them both. i know many will go b.o.b and say "what you're hoping to accomplish, i already did bitch.", that's cool as well, brag about your cool rig!8
the network at my job drops more than underwear at an orgy -.-
(variety of reasons, wifi is bad, and my vm hiccups the ethernet at least once a day)
luckily i move in a monthish4
I have a little big question
I don't have electricity most of the time but the ethernet cable from my internet provider is still working if i plug it in my laptop.
Except that i have to setup the credential from the provider, user and password.
I want to plug the ethernet into the raspberry pi (3B+) make it work , because idk where should i enter the credentials and then make hotspot so i can have a router powered up from the power bank.
A pi as router
Is it possible?
Because so far i have seen people who connect the pi to the router but mine requires electricity as any other else.
So I was playing with deauthing because I was curious about to and I got this little deauthing tool and I no joke fucked up my whole network for hours.
In my house we recently had tplink smart light switches installed and that created 40 more iot devices on the network. Soooo I disconnected them all at once and also cloned my AP so they went into this limbo state where they could not connect to anything and also for some reason Ethernet stopped working I think my isp thought I was getting a DOS attack or something idk but no joke took me hours to fix it.3
I fucking hate printers. And printers hate me too.
I've been working as a software engineer for almost seven years now, and not a single day as a printer technician, which does not stop my mother from calling me each time a printer breaks down, as she did today. I hop over to her place, the printer is connected via usb into the ethernet socket, but she swears it's been printing an hour ago, and she hasn't moved a thing. - "weird", I think, "it must be connected wirelessly". Suddenly my sister, who's an Arts major, comes over, saying her printer broke down too - "cool so they're both wifi printers". I reset the router and my sister's printer springs back to life.
But my mom's printer, which is old and in bad shape (the printer, not my mom! assholes...), doesn't. It keeps on displaying a weird error message, and fails to receive any print job, whether wired or wireless.
I spent 15 seconds resetting the router, and 15 minutes troubleshooting mom's printer. Nothing worked.
I finally give up and leave the house.
Not a minute goes by and I receive a "your sister fixed the printer" text from mom.
I fucking hate printers.5
Do anybody remember when i wrote a rant about the IT teacher in my high school?
Few months ago we got the results from final exams! (we have precentage based grades)
Another thing to remember:
You can pick basic or extended version of the every test you take.
Everybody has to get at least 30% on basic exams (they are nessesary for everybody) to graduate from the school. The extended exams give you more points at university and they are not mandatory.
In addition to that extended ones dont have the lower limit
The IT exam has only the extended version (because its not mandator, you pick it yourself). It is pretty easy: just basic algorithms, basic C++ programs and general PC things.
I didnt take the IT class because i thougt i can learn much more at home. My friend took it. He is very good. He uses linux he wants to become a pen tester. I know he is worth getting 100% on that extended IT exam. (We did a lot of projects thogether)
Well... NOBODY GOT MORE THAN 20% on that exam! WTF!
That POS teacher should die in that win xp IT class with all ethernet cables stuck in his ass!
He didnt teach anything useful about algorithms to anybody! And that was the easiest and the most important part on the exam!
In addition to that people had to do few tasks on pc as well! And one of those tasks could been a picture in gimp BUT THE GIMP DIDNT EVEN WORK ON THOSE PC'S!
Algorithms are easy! That son of a twat didnt even understand it himself! That is why im telling everybody in my town to NOT go to that hight school for IT exam!
I dont want anybody to waste their life trying to learn something useful when that fucking bitch dosent understand anything!
That teacher is lucky. My friend got rejected from studing CS on university (due to the shit score) but he at least got accepted to study math.
I hope he will be able to continiue his dev dream.3
I wish laptops were more easily modifiable. Ram upgrade? Gpu upgrade? 10-GBit ethernet? Maybe I should just buy a desktop...3
Will these fucktards just FUCKING FIX EDUROAM! alright it's a WiFi network that works across the globe and there's challenges with that BUT DON'T MAKE ME HAVE TO MANUALLY RECONNECT EVERY random amount of time!!! I'll shove that fucking MSCHAPv2 down you fucking throats with that sweet sweets PEAP sauce bloody arseholes.
What do you fucking mean it works fine? NO IT BLOODY DOESN'T! Get your shit together and at least handle DHCP leases correctly and make them not expire every fucking minute!!
Also, how the flipping fuck does connecting to the eduroam VPN from within fucking eduroam make it more stable? Only ever so slightly though. Incompetent pieces of dick sucking craptards don't make me have to bring out the ethernet jack EVERY FUCKING TIME at school for christ's sake.
No, it doesn't make it my problem because I'm running Linux. Look on the Internet. The forums are fucking filled with people having issues and your docs are from 5 years ago so please kindly FUCK Off!!!15
!rant seems that my raspberry pi serial idea is a little bit complex at the moment and may take a more serious turn later, but I have studied and found DOS based TCP/IP software that will allow me to use my 5150 with actual Ethernet. There are a few 8bit ISA Ethernet cards that will work in the 5150 and separate executables that will configure DHCP, DNS, and even allow me to use a terminal emulator and SSH to connect to *nix based computers over lan! I'll keep you all posted!6
My fucking internet went off and was so slow that even ssh resetted me, fucking thanks. And it was the same typical pattern again: turn off, turn on, kbps speed, wait ~30/50 minutes and then again fullspeed, fucking cuntbags stop fucking fingerbanging the ethernet ports - I need to get shit done.1
Oh boy... IM ANGRY!
My lovely ISP just sent me my new Reciever and router, they now are 2 seperate things, which shouldve made stuff easier for me... SHOULD have...
So I connected both with ethernet, power etc... and... nope...the Reciever didnt accept the Router... nice. very nice... after HALF an HOUR i finally got through Support, amd they said "Use your old Reciever/Router combo, we will activate the new one on monday" so I went like:
Ok, that should work!
And nope. For whatever reason as soon as my new Reciever was plugged in, it sent a message to the ISP which went like:
"Im on the net, deactivate the old one"
You know what happened now...
My old Reciever/Router combo is deactivated and my ISP cant activate it because the departement for this doesnt work on the Weekend...
And my new one cant be Activated because its seperate now and the Router isnt activated by my ISP...
Now im here, with my phone as a FUCKING HOTSPOT FOR EVERYTHING I HAVE!
Fuck you sysadmin, what makes you think that running a complete antivirus scan everyday at fucking 11am is a good idea?
What the fuck can I do with the fucking 5% CPU available? Should I play fucking Pong in an emulator? Write the story of my life with notepad?
Go hang yourself on an Ethernet câble in your fucking server room, you fucktard cunt.12
I don't understand why (or even how) I'm expected to be productive without a stable internet connection.
My computer doesn't have WiFi capabilities and the ethernet connection sucks too.
So, here I am passing time while waiting for Gitlab to load...2
I hate having 2 same looking keys.
My solution is to hot glue Ethernet connector to one of them. And the plug it into switch as a holder.
Sad thing it comes of easily and I need to solder it into place but I will do that other time.
I decided to run Ethernet to a different part of the house figuring oh that's easy enough, only 30 feet or so, I bet it will take 20 mins....
3 hours later after spending 2 fishing wire through an Arizona attic I am dehydrated and sore. When will I learn to stick to coding and leave the labor to guys with callused hands and ladders.3
So us Aussies are about to literally be forced into using NBN soon (for people who aren't Aussies, NBN would be worse than using a log of shit as your ethernet cable) and having all ADSL connections cut off... Fan fucking tastic!
They can barely keep the NBN up and running for one day and can barely deliver promised speeds but nooooooooooooooooooooo, everyone must fucking use it...3
Fuck Arch wifi handling!!! Why can’t you fucking just have the needed software in the base package!!! Because when you take YOU FUCKING USB INSTALLATION SOMEWHERE THERE’S NO ETHERNET!!! You’re FUCKED!!! What’s the point! Now I need to boot from my lubuntu usb dual boot install, FUCKING INSTALL the Arch iso, VirtualBox and then the needed wifi packages!! Fuck!5
College. The head Prof of the IT department tries to open a site without even looking at the networking icon, which says disconnected, meaning that the Ethernet cable was unplugged. Tries to refresh a couple of times.
Goes off to find a lab assistant.
Assistant comes is, plugs in the cable.2
I asked for Razer blade 15 base model for work purpose, considering about Ethernet port and all... Then my boss ordered 2TB option. Should I have asked for advanced model from the start? 😕10
Someone wanted to take a look to kde on Ubuntu 18.04 in my laptop, so did:
`sudo tasksel install kubuntu-desktop`
After rebooting and all did:
`sudo tasksell remove kubuntu-desktop`
and now I don't have GUI. The problem is that I can't also have network, neither by WiFi or ethernet. So I can't install packages.
The best way to fix that is to reinstall Ubuntu? Or there is a way to recover the ability to connect to network?
BTW, yes: "someone" was myself.
Shame on me 😔6
i often do tech support in chat rooms in my free time (because i like spreading good will,) so here's a tech horror story
"hey, can you help me fix something?"
"so i dug my old XP machine out of my closet and replaced the bad Ethernet card with a different one and when i plug in the ethernet cable the PC bluescreens."
did you install the drivers? Sounds like it needs drivers
then install them
"it doesn't need any"
why do you say that?
"it said \"This device is set up and ready to use.\" in the balloon in the corner"
it has generic drivers to deal with devices before the real drivers can be found
"shouldn't they work?"
some devices need the extra support provided by the intended drivers, so the generic ones cause issues in those cases
"ok, well, where do I find them?"
do you have a model number?
"yes, it's " # scrubbed for... privacy? i dunno
gimme a few minutes
<insert 45 minutes of aggressive Googling for (str(DEVICE_MODEL_NUMBER) + " xp drivers")>
alright i have the drivers, go here:
# again, removed for... idk.
"they don't work"
# oh here we go
"These drivers are not compatible with your system architecture."
what version of XP are you using?
x86 or x64?
ok so this is gonna get real complicated real fast: use x86 XP or I can't help you, none exist for x64 XP.

I was returning something at MicroCenter the other day. The guy in front of me was picking up a laptop be brought in to have fixed. They had replaced the motherboard, and put all his old data on an external drive.
"So what's this?"
"This is an external hard drive. We copied all the data from your laptop onto it and put a fresh install on it."
"So .. how do I get to it?"
"You just plug it in, over USB."
"So how ... how does that work."
This goes on for a while. Shop owner has to start his computer. Plug in the drive. There was a lot of, "So everything that was on here, is now on here?"
The guy had no basic understanding of external hard drives, USB, copying files ... thankfully while the files were copying from the hard drive to his desktop, he said he needed a longer cable to the router so he could put it on the other side of the room. It took the guy behind the desk an unreasonable amount of time to direct him to the isle with the Ethernet cables, but once he did, I was finally able to return my item.
I'm glad I no longer work in desktop support.1
This is the worst possible thing that can happen, when you setup a new computer.
I live for about a decade on ubuntu. I got an invite for a LAN where games are being played that I cannot run with wine or are not ported to linux.
Fine I get an old harddrive and setup a fresh Windows 7. I have a little update script that takes care of updating and restarting.
BUT I CAN NOT DO ANY UPDATES.
As you can see in the picture the original Windows 7 installation disc that was part of my computer did not carry the matching NIC drivers.
A friend of mine gave me a spare WiFi dongle. That did not bring its drivers on the USB dongle but on disc that he lost.
WHY?! HOW?! This is not plug and play. This is a part that SHOULD be plug and play.
After I got an other WiFi dongle that was plug and play, I could finally download the right drivers.
Why can the Windows 7 disc that was part of the computer setup not contain the right drivers, but a ubuntu 12.04 live disc can?!
Finally got my wall up to my desk in whiteboard. 4' by 8' sheets cut to fit the whole wall with a 1/8" clearance at the top. Ignore the raspberry pi, I have to set it up this way because I have no USB network adapter or long enough Ethernet cable. There should have been a magic mirror where the box is but on that specific spot in the wall the studs are only 13 1/2" instead of 14" like they should be...3
Does anyone here know how to setup a dual gateway network?
Router-1 connects to the internet via ISP-1
Router-2 connects to the internet via ISP-2
Both the routers are in the same building. Obviously, the server system can only remain connected to one router. I'd like to set up the network in such a way that:
-All systems connected to both the routers can communicate with each other and of course the server.
-If the internet connectivity from one router goes down, all the nodes in the network must automatically use the other ISP.6
I guess I should relate what work experience I have: my internship.
A little backstory I suppose. It's required at my school to do an internship to graduate except under certain circumstances. They encourage work experience a lot where I study. It was around time for me to apply for internships. However, the closest I got was a phone call with Amazon that I biffed when they started asking about stuff like sorting algorithms and other Big O notation stuff. So I was pretty desperate. I found a small company that were looking for internships and got an interview with them. The pay was dirt (I made more as a crew trainer at McDonalds) but I needed that internship and they were only 10 minutes away.
Immediate red flags when I showed up to the address. At first I thought I was wrong, But I noticed the sign of the company pointing up some stairs that were installed on the side of the house I was in front of.
Interview was a bit weird. It was with the CEO and the marketing manager. Again red flags. I show up for work a week later.
Turns out, they have no full time developers. 1st day was getting my workstation ready and 2nd day I was running Ethernet cables to the basement where the phones were connected. Spent around a week doing that.
This was supposed to be a Software Engineering internship?? Excuse me?? I came here to learn how working on Software is supposed to be like! I was also their "tech support" both for their computers and their crappy software that was built 16 years ago that people still pay for that I had NO idea how it worked because I just started and NOBODY taught me anything! To make matters worse, even if I wanted to delve into the code to see how it works it was all made in ancient Perl which didn't make things any easier.
But I needed that internship to graduate. And thus begun my 9 months with them and boy howdy I have stories to tell. Stay tuned in the future.3

I'll be honest, I was more exited than I would like to admit when my Ethernet switch came in the post3
So I just started watching Eli The Computer Guy's videos on networking and I really like them so far(only on the introduction so far though), but I was a bit confused about some of the stuff and I thought to myself that some of this might be obsolote or not so much in use these days/different. So here are some questions(now bear with me, I'm still a noob to the whole topic of networking):
-Are Eli's videos on networking obsolete(besides the speeds that he talks about), what you recommend some other tutorial, if so which one?
-Is a switch necessary for a small network?
-Do we still connect routers to modems or do we just use what we refer to as a router(a mix between a router and a modem -> gateway/gateway router)?
-Can you connect an ethernet cable to your router/gateway?
-So according to Eli if you have multiple routers they make seperate networks that cant just be acessed from each other, then how come it be that I can access my rasperry pi when I'm connected on the network of one router when the raspberry pi is connected to the network of another router and how come it be that once you have the wifi password you can connect to all of them?8
Under pressure for a big feature that had to be merged into develop like one month ago. But I couldn't because of issues I discover every single fucking day.
Today's issue is that a Cucumber test fails. I try reproducing it on my machine, it fails with a different error. Apparently I need to download some 10GB database file from some company server.
Alright, let's download it. But it's damn too slow. Well, let's have lunch in the meantime.
I come back, the download timed out at basically the same point I left it at.
I don't wanna try again. Not without trying to improve things. Download speed is ridiculous. Switching from Wi-Fi to Ethernet definitely helps, I thought.
The cable doesn't work. The port LEDs are both off. Is that cable even connected to something? So I follow that damn cable throughout my colleagues' desks. I'm now doing things without even remembering why.
I finally find the other end. It is plugged to the wall. I try another plug, but that fucking LED is still off. A colleague tells me: not all the sockets are actually connected to the switch, you have to call IT to have yours patched. Stay calm, stay caaaaalm...
A small lamp turns on in my head. Maybe something in my laptop is broken. So I try with a colleague's ethernet. That fucking LED is still off. A-ha.
Turns out, the shitty macbook adapter has this Ethernet port that DOESN'T work out of the box. It needs a driver to even realize there's a port. I look for it, I find it. I finally have wired connection. It's like having drinking water again.
I turn off WiFi, I re-try downloading that fucking database.
Nope, it's still stupidly slow. The bottleneck was in the dumbfuck internal server.
At least I have Ethernet now.1
I have overwritten some files that make my WiFi-module work and I can't reinstall it, because that doesn't fucking work!! (Ethernet is also giving up on me😢)
NOW I HAVE TO FUCKING REINSTALL FUCKING UBUNTU, BUT MY LAPTOP WON'T BOOT FROM THE FUCKING USB!!!!4
A colleague of mine was assigned to do a manual testing of application. It involved testing application in no-network / offline conditions.
While doing this he disconnected the virtual ethernet of Remote desktop thus crashing the VM forever....
Dear Elon Musk, send him to Mars right away.2
## building my own router
I hoped things would go more smoothly :)
Anyway, my new miniPC easily accepted CentOS 8 - no fuss here. And I've got to say - I love CentOS8 so far! Shell has amazing nifty tricks, UI (gnome3) is also snappy, video/audio/ethernet,.. everything works.
What I did NOT expect is hardware being off. Well okay, the price was low - it was obvious smth is not right. But still.. I decided to build my own router so that I could swap wifi card whenever I want. So that I could run my own network services in there. Turns out - the card swapping is not as easy as one might think.
I got the AX200 WiFi6 card for that very purpose. But once plugged in the OS can only see it's bluetooth module. Weird... What's even weirder is that even though the card is PCIe, the OS uses btusb module to talk to that device. What? USB?? emm.. What??
And there it is. After opening it up again I noticed that the mPCIe area is marked with a label: "USB WIFI / WWAN". USB? Does that mean this PCIe slot is wired into the USB bus? Not impossible I guess.
Googling for a "pcie wifi over usb" or smth like that brought me to one reddit (I think?) where someone wanted to build a DIY wifi mPCIe -> USB adapter and someone else adviced hime that (for some reason) at best he could only get bluetooth working (hey! just like me!). It's got to do smth with pcie channels and USB being too weak to handle all that load, or smth.. IDK, I'm not a HW guy.
Well that sucks then! I have a mPCIe slot that does not work as a PCIe. Shit! So I guess the best I could do is to plug back in the same wifi card that came with the device. It smells like 2003 - supports only g protocol. Fine, let's try that. Maybe I'll find a way to work around this mPCIe limitation later on (USB adapter or smth... except there are no USB WIFI6 dongles yet :( ). So I plug it back in and start turning it into a router. Disable NetworkManager, configure static NCs' settings, install dhcpd, hostapd, bind and others. Looks like all is done! Now it's time to start it all. systemctl start hostapd --> FAILED. wtf? journalctl says it could not initialize a driver. umm okay? Why? Forums say I should airodump-ng check and kill whatever's using that device. Fine. airodumo reveals avahi and wpa_suppl are still using it. kill, kill, GOTTA KILL 'EM ALL!! Starting hostapd again -- same shit... wtf?
My gawd... That shitty network card does not even support AP mode :( I mean.. My USB wifi dongle for 2€ supports 2x more modes, is faster, has better range and is easier to work with than this old tart!
Yeah. That was an interesting day. When enfironment engineers break my testing environments at work I'm glad I have where to spend my time now.
BTW any ideas how to bypass this mPCIe nonsense? Come on, there are USB GPUs out there.. Why can't they make a USB (or dual-USB if they really need to) mPCIe adapter?11
When your PC is slow af cause of the hard disk so you make a dumb decision and change your hard disk with a new one and you gotta install Windows on it but you only have very old images of it so it requires a special USB driver to install the system and THEN you realise the setup image has NO DRIVERS for ethernet, wlan OR usb so you can do absolutely NOTHING with your fresh system so you decide to install linux instead but you realise YOU'VE REMOVED ALL X64 IMAGES BECAUSE YOU'RE FUCKING DUMB SO you prepare a bootable Kali USB to copy basic drivers and DriverBooster into the hard disk to install them on Windows.
AND THEN YOUR FRIENDS CALL YOU AND TELL YOU THAT YOU HAVE 2 EXAMS TOMORROW BUT YOU CAN'T JUST LEAVE THE COMPUTER SO YOU JUST GO FUCKING KILL YOURSELF
This is why I HATE MY LIFE SO MUCH IT GOES SO WRONG !!!!4
There is no joy in life
So I finally managed to set up networking on my 3D printer's raspberry pi: now it can connect to my phone's hotspot or to my uni's wifi network, depending on which is available.
Then I set up OpenVPN, using a remote server as a middleman so I can connect to the printer remotely and start/stop/monitor prints from anywhere.
Everything works great, except for one thing: whenever the Pi connects to the uni's network first, OpenVPN fails to start and connect to my server, rendering the printer unavailable (unless I use an ethernet cable, but that's not a viable operation since I need to lift the printer, and it's heavy).
The only for it to work as intended is to either:
a) keep my hotspot active (which kinda defeats the point), or
b) let it connect to my hotspot first (so that OpenVPN can start properly) and then turn off the hotspot, allowing the printer to reconnect to the uni's wifi and reconnect to my vpn.
Why won't things just work the way they're supposed to? 😭10
Windows diagnostic tool wants to search for a solution to my desktop's network problems on the internet :/
Plus, I discovered my Windows installation created 40+ ethernet connections on its' own behalf... Time to wipe Windows.. :/
Luckily I use Linux on my Notebook...2
cables. lots of cables. also, an ethernet switch.
But the toys I have (and other ppl keep burrowing) is a dalek, tardis minuatures - about 6cm Height (2.1"), and lvl 5/6 hanayama metal puzzles.4
Anyone else really fucking despise the fact that OSX opens location tracking every time a wifi or Ethernet is connected and as far as I’ve found it can’t be turned off.
I’m ok with a service doing it on a request but not an OS that’s clearly gathering information. If I didn’t have to use it I’d throw petrol on it and burn it to the ground2
What would it take to connect two Raspberry Pi's together via Ethernet ports? I want to make a low latency network connection between them, for Retropie Netplay.
I have a background in Python and some Linux, but I'm not well versed in raspi's.
I imagine that it would be limited to 100mb/s if I used raspberry pi zeros with adapters. And I would probably need an router since they aren't setup to be both hosts with the default setup?2
Disconnected a production servers Ethernet adaptor ten minutes early. While people were working on it, and its failover was not quick...like five minutes not quick. Why isn't there a confirmation box on that Microsoft...2
Im thinking about getting a raspberry pi 3 or an odroid-c2.
(Specs at the end)
Its to host a simple php server and maybe a gitlab server, both for personal use.
Should I go with the better performance or the better community support?

I'm kinda amazed at how simple it is to host my private git server on my raspberry pi. That being said I couldn't get it to work well as an access point with hostapd. Therefore pushing and pulling while on my home wifi works like a charm, but doing this in public requires ethernet. Having an Ethernet run from outside my backpack really does make me look like some hacker terrorist person, especially in NYC7
Today I broke the quarantine to buy an HDMI splitter.
Turns out the secondary monitor I have is old as fuck so I can not extend the display, only duplicate 🤦🏼♂️
50€ to the garbage.
At least I bought a big ethernet cable to plug it on my PC and now I have 120mbps instead of the 2/3 I had on WiFi14
Network management from the terminal is such a pain in the ass on linux! Far too many different config files in many different places, and I have no idea which works with which!
Just now I managed to fuck something up in my RPi's config, so I don't have wifi access anymore and I didn't have time to find its ip address while connected through ethernet :/
I feel accomplished. After arguing with my family for a month or so, I finally solved the WiFi issues in my room! (We live in a flat. And the thick, concrete walls eat the signal super well)
I used to have 2 MBs downstream at most, with very common disconnects and general connection issues.
Now, just yesterday, I laid about 50 meters of ethernet cable all the way from my room to the other end of our house. Laid the cable along the top of our walls so that mom did not have to constantly whine how bad it looks.
Biggest issues were doors (Parents refuse to drill into the walls here, they tend to crumble a lot), but ended up running it under the door just tightly enough that the doors don't squeeze it in any way.
It works great! The cable is almost invisible, and now, my downstream is 30 MBps!
The only downside is that I used an old wifi router in my room that supports only 802.11b/g/n, not ac.2
I decided to try out that built in mobile hotspot in win10 but my phone keep couldnt get IP from it.
I tried everything to fix this.
After 2 hours of searching the internet i bumped into an idea.
Pulled out the ethernet cable and plugged in.
I cant look at myself in the mirror...
Does anyone else struggle with I-want-this-to-work syndrome where you try to make something work that’s really specific and random but that you want to do and you spend way too long trying to get the tiniest bits to wrk and end up abandoning it after hours of wasted time?
Examples from me: trying to get an Ethernet cord to act like an AUX cord but using networking protocols so I can use my fucking sonos as, you know, a proper fucking computer speaker for fucking pc sounds instead of just streaming.
Trying to hook up a piece of exercise equipment to their own software that displays cool stuff except their software is only for windows and you only use/want to use Linux and you have to deal with HID devices through WINE and are ultimately just procrastinating your workout
Anyone got similar stories or tips?2
So I'm working on some communications app which bridges the main server/database with some equipment on the field. Now this equipment works in a redundancy pair: two cpus, A and B, both connected via ethernet, one active, the other standby/replicating and no comms on it. One obvious requirement is that when this equipment swaps the active cpus the comms app should switch as well. Fair enough, going with this into testing phase.
This guy, from qa, got some instructions from someone else:
1. Trigger the soft switch from equipment so that cpus got swapped.
2. Remove the ethernet cable from the standby unit.
3. Observe the communications.
And the test goes like: cpu A is active, B is standby. Switch is triggered, B becomes active, A goes into standby. The cable is pulled out from cpu B.
Test result: failed, no comms ever4
Worst coding mistake: accidentally overwriting part of the address field in an Ethernet frame instead of the vlan tag when developing a network switch...
Speaking with my former coworker about networking:
Me: Coaxial uses the Ethernet layer two protocol.
Coworker: No? Coax uses the RADIUS layer two protocol.
And this guy was my "superior."
I needed to install an extra Ethernet card on my machine at work. The process of getting it from the IT department was fairly easy, but the damn things didn't have the small screws you need, in order for the card to not hang on the PCI-E port...
Turns out finding that kind of screws is way more annoying than the card itself. :/ I don't get why they were not included, if they are essential for the operation of the card...5
So I ran into a perplexing "issue" today at work and I'm hoping some of you here have had experience with this. I got a story-time from my coworker about the early days of my company's product that I work on and heard about why I was running into so much code that appeared to be written hastily (cause it was). Turns out during the hardware bring-up phase, they were moving so fast they had to turn on all sorts of low level drivers and get them working in the system within a matter of days, just to keep up with the hardware team. Now keep in mind, these aren't "trivial" peripherals like a UART. Apparently the Ethernet driver had a grand total of a week to go from nothing to something communicating. Now, I'm a completely self-taught embedded systems focused software engineer and got to where I am simply cause I freaking love embedded systems. It's the best. BUT, the path I took involved focusing on quality over quantity, simply because I learned very quickly that if I did not take the time to think about what I was doing, I would screw myself over. My entire motto in life is something to the effect of "If I'm going to do it, I'm going to do it to the best of my abilities." As such, I tend to be one of the more forward thinking engineers on my team despite relative to my very small amount of professional experience (essentially I screwed myself over on my projects waaaay too often in the past years and learned from it). But what I learned today slightly terrifies me and took me aback. I know full well that there is going to come a point in my career where I do not have the time to produce quality code and really think about what I am designing....and yet it STILL has to work. I'm even in the aerospace field where safety is critical! I had not even considered that to be a possibility. Ideally I would like to prepare now so that I can be effective when that time does come...Have any of you been on the other side of this? What was it like? How can I grow now to be better prepared and provide value to my company when those situations come about? I know this is going to be extremely uncomfortable for me, but c'est la vie.
TLDR: I'm personally driven to produce quality code, but heard a horror story today about having to produce tons of safety-critical code in a short time without time for design. Ensue existential crisis. Help! Suggestions for growth?!
Edit: Just so I'm clear, the code base is good. We do extensive testing (for lots of reasons), but it just wasn't up to my "personal standards".2
Why is it that windows 10's network adapter takes so fucking long in order to work and connect to the internet!!
Does anyone know a way to trace back what's causing it? And why it takes like full 15 minutes for the Ethernet or wifi drivers to even work? (I'm not even sure if this is something with the drivers or the way windows's network adapter way of working)
I couldn't find Jack shit on the internet (most of them are ghetto do this and that and hope it works) I want something more advanced so I can figure out for once why this happens on numerous windows computers
(Linux people, I understand you, please don't rant your stuff here, this is a bit serious issue, thx)6
sadly my old laptop is dying (first was the hdd, then came the battery; today the keyboard just shut down, and the trackpad followed shortly). The warranty is expired, so I was thinking about a new notebook. I was looking around but I didn't find pretty much anything interesting.
So, I'm asking you for some advice on the matter, considering the following factors:
- I currently live in Italy and I'd like to keep the Italian keyboard layout, as well as the power socket;
- I usually buy everything on Amazon (Italy), but I don't mind any other online shop (in Italy), as long as they are trustworthy.
That being said, these are some of the specs I had in mind:
- screen size between 13" and 15.6", FullHD (or better), matte over glossy. I don't care about touchscreen;
- Intel i7 Kaby Lake (7th gen) or Kaby Lake Refresh (8th gen) CPU. Not the U series or any other undervolted revision;
- 16GB of DDR4 RAM (2400MHz or better);
- SSD as main storage (at least 128GB) and secondary HDD/SSD slot;
- I don't care about the GPU (right now I don't have to play :_( );
- the whole laptop (core + battery + etc.) should weight less than 2.3kg or ~5 pounds;
- it has at least one USB 3.0 TypeA port, and an ethernet port (and of course WiFi, Bluetooth, etc.);
- a price of €1200 or less (I can probably spend a little bit more for something I'm truly enthusiast of).
Thanks in advance for your time.6
So today my teacher told me to do that project for some competition or something(frankly, I don't remember clearly what this is for). He gave us the machines we need, the CDs with the systems we have to work with. We are supposed to make a properly working Beowulf cluster from the things I've been given.
I am really okay with making this the way my teacher wants us to do. I am okay with installing an ubuntu 16.04 server that is completly irrevelant to the project, because it's not part of the cluster. I am really okay with using some weird linux distribution on the master nobody has ever heard of. But I'm not okay when the software we've been given(including operating system) has seven pages of documentation, escpecially when fucking screenshoots of how PXE booting should look like are roughly 70% of it. No, I couldn't find a thing on the internet about it. I couldn't read the fucking manual. There was no fucking manual. There was no fucking --help. There was no motherfucking english language. Everything was motherfucking spanish, including that 7 pages long document that was supposed to guide us through our work. It was planned to be done until march. The only reason I can think of about why doing the stuff the document tells us to do would take four motherfucking months is that we'd have to learn spanish to do this. And I'm not going to do that. Not because I don't like spanish or learning. Simply because I didn't sign up for this to learn languages.
And no. I can't switch to other, human purposed software. I am only allowed to use the things the teacher has given us. Because somebody has worked on it already couple of years ago and they had left a pdf file about how to install that ubuntu server I've been writing about a while ago. Which, by the way, was the "installation guide for animals". Showing how to install a system, screenshoot after screenshot.
It took about an hour to figure out the thing supposed to handle pxe booting computers all the time was telling us that it can't work because we had to configure ethernet interface manually. Because why the fuck not.
Decide to move to docker for windows from toolbox. Worked well until vpn/s-tunnel all crapped out.
Found out about hyperv, default ethernet, HNS, windows DNS etc etc getting confused.
Removed docker and hyper v, back to working again.
Interface index for adapter selection , really ?
This is the weirdest thing that have happened to me related to computers... When I connect an ethernet cable to my computer and I use the iex command (Interactive Elixir or elixir console, whatever) on my terminal it takes about 6 seconds to load but when I disconnect the cable and use iex again it starts instantly, like, what the fuck. This happens with any Elixir command. I've had this problem for several days and honestly I didn't know why it was taking so long to load.4
I had to share my laptops wifi internet with my desktop using ethernet. Microsoft has a dedicated feature of Internet Connection Sharing and it didn't work.
But manually bridging connection adapters got the fucking job done.
Just Microsoft things.2
So it's basically impossible to install Arch Linux on a MacBook without an Ethernet cable.
I downloaded the wi-fi drivers and put them on a separate USB and then tried to compile them in archiso, but without success3
Because I dev, people think of me as a tech guru to consult on everything related to anything more tech than a stone.
Like guiding people on how to insert their ethernet cable when "the internet suddenly shut down".2
So today was going to be the Sunday when I finally connected my smart TV though my raspberry pi to access my network and have it connect to the internet.
My TV is 6 years old, so it doesn't have built in wireless, it does not recognize normal Wifi dongles so you have to buy a LG special one for ~120$ to get hat to work, so my previos solution: screw that, one chromecast + 1 osmc raspberry pi3 and I can do more than what the software build in the TV could do.
But my wife really wanted to be able to play netflix directly on the TV without using her phone so I thought:
If I connect my TV via LAN cable to my raspberry pi it should be able to forward traffic via the built in wireless on the raspberry and be able to have internet connection.
OK, its Sunday, my wife it out, I haven't done anything with iptables in the last 5+ years but I have google and should be able to figure it out eventually:) time to start this home improvement project!!!
OK, lets just check online if there is someone else who had similar idea as a place to start.
... quick google search:
Hmm, in your OSMC, go to teathering, "wifi to ethernet" and enable.
I try it and it works!
5 min and one short ethernet cable was all that were required.
It feels like I cheated and won the game without any effort, and what should I now do with the rest of the day?
If I'm at the library.
And there are Ethernet ports.
Desktop computers are connected to it and working fine.
But when I try to unplug it and connect my laptop with it it's just doesn't work, as if it says there is no Ethernet connection at all.
What are some of the reasons for such thing?
Do I have to look up specific IP configuration and configure it on my laptop?
Do these windows domain system matter?
How can I get started figuring why it says it's that there's no connection in the first place?
The librarians know Jack shit about why it's not working.
And I can't find the technician contact address to ask him/her/them directly.
WiFi works fine, but slow, Ethernet connections has a gigabit connection. (I believe that should explain why I want to use that instead)6
Yesterday I wanted to give Gentoo a try. I could not even get the ethernet working on the fucking live-USB. Guess no Gentoo for me.
Holy fucking shit, I hate ubuntu SO much.
So what it happened..
I was tryin to set up an Ubuntu server on my machine using virtual box, and I know what you are thinking, "VirtualBox?" yeah its the only machine I had lying around and it had windows and I didn't wanna re-format its hard drive.
So Here how it goes...
Install went fine.. But when I was trying to manage multiple network interfaces, it was Terrible & pain in the ASS 😡...
So initially I needed 2 network interfaces, one for NAT adapter and another Host-only interface for SSH and stuff.. so I made changes in virtualbox settings and rebooted the VM. and it stuck on "a start job is running for wait for network to be configured" I was like okayy and removed host-only adapter and rebooted, it booted fine :/ then I tried combo of bridged adapter with my Ethernet and a host-only adapter, and what? it booted finally! but this wasn't an optimal solution because it had and IP address within subnet of other devices with my router and half the bandwidth (like 50mbps or something).. I reverted back to NAT network & I checked with ifconfig and it STILL didn't had an IP address assigned to it for Host-only adapter!! FFS I deleted the VM and reinstalled the whole thing again but this time both interfaces attached..
after installing it stuck on same shit again :'(
"a start job is running for wait for network to be configured"... FUCK!
after about an hour of troubleshooting and trying different configurations, I still couldn't get it to work.. I never had such problems with centOS.
Fuck you ubuntu.. fuck you in the ass7
In a quiet, closed space unhindered by distractions.
For me (and I'd imagine, many others here), constant conversations in the background, people walking by, etc absolutely kill my focus and keep me from getting work done. Working from home helps a bit, but my neighbors provide plenty of their own distractions.
Honestly, I'll take a broom closet with a laptop, headphones and an Ethernet jack over any other open office design.
Ethernet switch is broken
This happened last week, parts of our lan was working so could still connect to our svn server but no internet at work for a couple of days bar stack overflow on my phone.
So as a personal project for work I decided to start data logging facility variables, it's something that we might need to pickup at some point in the future so decided to take the initiative since I'm the new guy.
I setup some basic current loop sensors are things like gas line pressures for bulk nitrogen and compressed air but decided to go with a more advanced system for logging the temperature and humidity in the labs. These sensors come with 'software' it's a web site you host internally. Cool so I just need to build a simple web server to run these PoE sensors. No big deal right, it's just an IIS service. Months after ordering Server 2019 though SSC I get 4 activation codes 2 MAK and 2 KMS. I won the lottery now i just have to download the server 2019 retail ISO and... Won't take the keys. Back to purchasing, "oh I can download that for you, what key is yours". Um... I dunno you sent me 4 Can I just get the link, "well you have to have a login". Ok what building are you in I'll drive over with a USB key (hoping there on the same campus), "the download keeps stopping, I'll contact the IT service in your building". a week later I get an install ISO and still no one knows that key is mine. Local IT service suggests it's probably a MAK key since I originally got a quote for a retail copy and we don't run a KMS server on the network I'm using for testing. We'll doesn't windows reject all 4 keys then proceed to register with a non-existent KMS server on the network I'm using for testing. Great so now this server that is supposed to connected to a private network for the sensors and use the second NIC for an internet connection has to be connected to the old network that I'm using for testing because that's where the KMS server seems to be. Ok no big deal the old network has internet except the powers that be want to migrate everything to the new more secure network but I still need to be connected to the KMS server because they sent me the wrong key. So I'm up to three network cards and some of my basic sensors are running on yet another network and I want to migrate the management software to this hardware to have all my data logging in one system. I had to label the Ethernet ports so I could hand over the hardware for certification and security scans.
So at this point I have my system running with a couple sensors setup with static IP's because I haven't had time to setup the DNS for the private network the sensors run on. Local IT goes to install McAfee and can't because it isn't compatible with anything after 1809 or later, I get a message back that " we only support up to 1709" I point out that it's server 2019, "Oh yeah, let me ask about that" a bunch of back and forth ensues and finally Local IT get's a version of McAfee that will install, runs security scan again i get a message back. " There are two high risk issues on your server", my blood pressure is getting high as well. The risks there looking at McAfee versions are out of date and windows Defender is disabled (because of McAfee).
There's a low risk issue as well, something relating to the DNS service I didn't fully setup. I tell local IT just disable it for now, then think we'll heck I'll remote in and do it. Nope can't remote into my server, oh they renamed it well that's lot going to stay that way but whatever oh here's the IP they assigned it, nope cant remote in no privileges. Ok so I run up three flights of stairs to local IT before they leave for the day log into my server yup RDP is enabled, odd but whatever let's delete the DNS role for now, nope you don't have admin privileges. Now I'm really getting displeased, I can;t have admin privileges on the network you want me to use to support the service on a system you can't support and I'm supposed to believe you can migrate the life safety systems you want us to move. I'm using my system to prove that the 2FA system works, at this rate I'm going to have 2FA access to a completely worthless broken system in a few years. good thing I rebuilt the whole server in a VM I'm planning to deploy before I get the official one back. I'm skipping a lot of the ridiculous back and forth conversations because the more I think about it the more irritated I get.1
Anybody like to rip up CTF (or similar)? I've honestly never done a CTF before, I'd like to give jt a shot. I'll get my ass handed to me because I'm not back up to par on OpSec yet, but I adapt well and when I get into a nice groove I can make shit happen! (I like to think so, anyways haha!!)
I've been in full on dev mode lately and haven't had any time to Hulk Smash for a while... I went to fire up a new Kali live USB today and I couldn't run through the updates like I always have- they changed sooo much and I was pissed because I didn't have ethernet with me. That'll be another day for sure, but I still have my machine with Manjaro armed to the nutsack and back with the BlackArch rep. I def could use a break from the chaos, and getting my ass handed right to me sounds like an awesome time because learning is my favorite thing next to a possible chance at getting to destroy shit.
It's weird, because I'm sort of a n00b but also at the same time I've had computers ripped apart/jammed in my face since every day since I was 9 and Y2K was about to hit the fan lmao!! My hardware/network/layering knowledge is fuckin mint titties, I just can't code like a fuckin madman on the fly. I don't have a "primary" language, because I've been having to work with little bits of several languages for extended periods of time... I can at least find my way around all the dox without much of an issue and have no issue solving the probs I come across which is neat, but until the day comes where I can fuck a gaping hole through my keyboard on the fly like George Hotz during one of his lazy Sunday OpenCV SLAM/Python code streams all jacked up on Herba Mate hahahahaha!!!!
The dude uses fucking VIM and codes faster than anyone I've ever seen on levels of science/math so challenging I almost shit myself inside out when I catch one!!!! The level of respect I have for all my fellow red pills in here is as high as it gets, and that's one of the best parts about being a code junkie- sometimes ya get to cross paths with beastly, out of this world people that teach you so much without even having to explain shit.
If anyone's down, or maybe has some resources for me to check out so I can get my chops up let's make it happen
Alright sure this quarintine time would go with no issues... Right?
*Waits 30 seconds*
*Page loads without the logo*
*Searches about a problem I have*
*Wait another 60 seconds*
*Page loads with no results*
*Waits another 40 seconds*
*Now there are links*
*Clicks on the first link*
Yep.... Fun shit.4
And so again I'm here asking for your opinions.
My old router (linksys EA6400) had a meltdown yesterday and decided to lose wifi connectivity every 4-5 seconds for 4-5 seconds each time. So it was like 5 ICMP packets pass and then 5 fail, and this pattern held up through the whole day.
Did a hard reset hoping it will help. Little did I know.. Do you even imagine how fun it was setting it up with randomly not working wifi? :D And this router can only be set up over wifi. I had to count seconds in my head predicting when it will start losing packets. Because when it does - the setup fails :)
So I guess it's time to start looking for a new one. I barely use ethernet ports (one for RPi). But I do need a good wifi. AC is a must. AX is not since none of my devices support it. I'd also like it to have open-source firmware, maybe accessible via shell (100% dd-wrt/open-wrt compatible). A USB port would be a plus (for the RPi).
Do you have any suggestions worth looking at?
What do you think about WRT3200ACM MU-MIMO?
Also I came across something called MESH ROUTERS (wtf is that?). http://linuxgizmos.com/low-cost-802.... Is it worth looking at?
What would YOU suggest?11
Hello everyone apples india online store webt live today at 10 AM . Sorry for late post. Also WTF is apple doing. Their macbook air has only two thunderbolt 3 ports. A machine this expensive must have atleast 3 thunderbolt 3 ports and 4 ideally if it does not have any other ports. I need one for a monitor and one for plugging in a ethernet or a port hub or a second monitor and a third to charge it. And if there are 4 a dual monitoe setup, a port hub and one for charging6
Infineon infineon infineon...
Your aurix tricore is amazing for all safet systems... On paper.
Your support is abysmal. Tried forums, support line to verify a demo that only seems to work sometimes.
I just wanted to get ethernet communication using the demo. But hey one week gone and no success....
And the code seems to behave differently for each run :| the debugger works only on global variables and no printf statements. But hey just make a lot of globals right? So little footprint available so not possible :-\
Hoped that some forum could confirm the demo so I knew I was just making a fuck up, but cannot get that verified...
Embedded programming not for me... :/
I am working on an embedded system, a microcontroller-based design. The system has an Ethernet port. I am using NetX framework in the microcontroller firmware.
The DHCP Client is executed properly, an IP address is assigned correctly when connected to a router. I connect a laptop to the router using a LAN cable. Then TCP sockets behave the way they should, UDP broadcast behave the way they should. The only issue is, when I connect a Laptop over wireless to the same router UDP broadcast are received on application on Laptop, but data sent is not received on the embedded device.
Any idea why?
Laptop is Windows
Embedded Device: Renesas S7G2, NetX framework.5
Anyone have experience with Hackintosh, I made a build yesterday but don't have some kext for ethernet and a Nvidia gtx xD
