What it's like to be a network engineer...translated into normal people speak
User: I think we are having a major road issue.
Me: What? No, I just checked, the roads are fine. I was actually just on the roads.
User: No, I’m pretty sure the roads are down because I’m not getting pizzas.
Me: Everything else on the roads is fine. What do you mean you aren’t getting pizzas?
User: I used to get pizzas when I ordered them, now I’m not getting them. It has to be a road issue.
Me: As I said, the roads are fine. Where are you getting pizzas from?
User: I’m not really sure. Can you check all places that deliver pizzas?
Me: No I don’t even know all the places that deliver pizza. You need to narrow it down.
User: I think it is Subway.
Me: Okay, I’ll check…No, I just looked and Subway doesn't deliver pizzas.
User: I’m pretty sure it is Subway. Can you just allow all food from Subway and we can see if pizza shows up?
Me: Sigh, fine I’ve allowed all food from Subway, but I don’t think that is the issue.
User: Yeah I’m still not getting pizza. Can you check the roads?
Me: It’s not the roads, the roads are fine. I’m pretty sure Subway isn’t the place.
User: Okay, I found it. It’s Papa Johns.
Me: Okay, I looked and Papa Johns does deliver pizza. Is it the local Papa Johns or one in a different town?
User: I don’t know. Can you allow pizza from all Papa Johns to me?
Me: No I can’t do that. Can you get me an address for Papa Johns?
User: No, I only know it as Papa Johns. Can you get me all the addresses of all Papa Johns and I’ll tell you if one of them is correct?
Me: No, I don’t have time for that. Okay, I looked at the local one and it looks like they have sent you pizza in the past and they are currently allowed to send you pizzas. Try ordering a pizza while I watch.
User: Yeah still no pizza. I’m guessing they are getting blocked at the freeway. Can you check the freeway to make sure they can get through?
Me: No, this is a local delivery. They aren't even using the freeway.
User: Okay, well then it has to be a road issue.
Me: No, the roads are fine. Okay, I just drove from the Papa Johns to the address they have on file for you and there is nothing there.
User: Hmm, wait we did move recently.
Me: Did you give your new address to Papa Johns?
User: No, I just thought they would be able to look me up by name.
Me: No they need your new address. What’s your new address?
User: I’m not really sure. Can you look it up?
Me: Sigh, give me a second…Okay, I found your address and gave it to Papa Johns. Try ordering a pizza now.
User: HEY! PIZZA JUST SHOWED UP!
Me: Okay, good.
User: (To everyone else they know) I apologize for the delay in the pizza but there was a major road issue that was preventing the pizza from getting to me. The network engineer has fixed the roads and we are able to get pizza again.
Me: But it wasn’t the roads…whatever.
User: Oh, can you also check on an issue where Chinese food isn’t getting to me? I think it may be a road issue38 -
My Neural Network can recognise handwritten digits!!!
It's my second try at NN so it's faaaar from perfect (or maybe even good), but hey, it's something and only with High schools, I'm pretty satisfied with the results. If you've not seen my previous post, I'm just trying to learn NNs in C and am doing just really basic things.
Still I'm proud of my progress!
Now I'm looking forward learning some library (OpenNN + OpenCV seems cool) and trying more advanced stuff, wish me luck 😆

User Ip Address is too long (maximum is 30 characters).
Okay, dear third-party API, I guess users with IPv6 don't deserve the service... And wtf is 30-char limit for an IP address, when IPv4 can be only 15 characters long, and IPv6 can be up to 39 characters? Did you calculate a weighted average of IP length to get that number?11 -

So, continuing the story, in reverse order, on the warship and its domain setup...
One day, the CO told me that we needed to set up a proper "network". Until now, the "network" was just an old Telcom switch, and an online HDD. No DHCP, no nothing. The computers dropped to the default 169.254.0.0/16 link local block of addresses, the HDD was open to all, cute stuff. I do some research and present to him a few options. To start things off, and to show them that a proper setup is better and more functional, I set up a linux server on one old PC.
The CO is reluctant to approve of the money needed (as I have written before, budget constraints in the military is the stuff of nightmares, people there expect proper setups with two toothpicks and a rubber band). So, I employ the very principles I learned from the holy book Bastard Operator From Hell: terrorizing with intimidating-looking things. I show him the linux server, green letters over black font, ngrep -x running (it spooks many people to be shown that). After some techno-babble I got approval for a proper rack server and new PCs. Then came the hard part: convincing him to ditch the old Telcom switch in favour of a new CISCO Catalyst one.
Three hours of non-stop barrage. Long papers of NATO specifications on security standards. Subliminal threats on security compromises. God, I never knew I would have to stoop so low. How little did I know that after that...
Came the horrors of user support.
Moral of the story: an old greek saying says "even a saint needs terrorizing". Keep that in mind.4 -
The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
I JUST FINISHED MY FIRST NEURAL NETWORK!!!
But first of all, as I know you guys, it's spaghetti code and even I as a newb see places where I used too few-dimensional array or passed useless parameters or simply wrote too many redundant lines of code. I know it. I will make it MUCH better next time. Period.
But OMFG this made me scream from happiness today!! Just these few seemingly random numbers... I'm really done.. That's why I jumped into coding year or two ago..
And for some background, I didn't study any IT school, I'm just highschooler (general grammar school) who traded gaming for learning. Also my maths teacher teached NNs on university and is very keen to teach me, so that's that.
Now I wanna make the best out of it and I'm looking forward to write some well documented and flexible library, parallelized and everything (I'm gonna learn a lot in the process of doing this) better then FANN.
Maybe I'm gonna fail(99% probability but hey, I'm programmer beginner, I still think I can code everything I want). But if there is just one moment like when I saw this screen today, I'mma trade my life for it.
Sorry for taking your time guys, I was just genuinely stunned... A lot

Lord forgive me for laughing too hard at this person/situation... I kid you NOT!
So today while everything was going well, we suddenly had network issues at work. We worked to get everything back up online asap and then sent out an email for those affected to either restart their machines or refresh their desktops but we recommend restarting... After some few client calls, this special call came in..
Riiing, riiiiiing, ring....
Me: hi, how can help you?
Client: *laughing.. This is probably a stupid question but I forgot how to "refresh" my desk top..the thing is, I have Febreeze but I don't think that's for desk tops.
Me: Wait, what? 🤔 Febreeze for what?😕
Client: You guys sent an email to refresh our desk tops and I said I have Febreeze so how will that get my things in the computer back to show again?
Me: Ohhh, no no. We meant your computer desktop. You don't need Febreeze. Right click anywhere on your computer in the screen and select refresh from the pop up menu. We meant your computer "desktop" not your actual "desk top".
Client: *starts laughing...I told you it was a stupid question
Me: don't worry.. It wasn't stupid.
After I hang up, some of my team members asked me why someone is asking about Febreeze...I told them and they all started laughing hysterically
I was still trying to digest the conversation I had just have on the phone. 😂😂😂12 -
My friend typed "hack" into a .bat file on our school network and got an after-school detention and his account disabled for like a week because he simply had the intention of trying to hack the network....5

--- UK Mobile carrier O2's data network vanishes like a fart in the wind ---
One of the largest mobile carriers in the UK; O2 has been having all manner of weird and wonderful problems this morning as bleary eyed susbcribers awoke to find their data services unavailable. What makes this particular outage interesting (more so than the annoyingly frequent wobblers some mobile masts have) is that the majority of the UK seems to be affected.
To further compound the hilarity/disaster (depending on which side of the fence you're on), Many smaller independent carriers such as GiffGaff and Tesco Mobile piggy-back off O2's network, meaning they're up the stinky creek without a paddle as well. Formal advice from the gaseous carrier is to reboot your device frequently to force a reconnect attempt, Which we're absolutely sure won't cause any issues at all with millions of devices screaming at the same network when it comes back up.
Issue reports began flooding DownDetector at around 5am (GMT), With PR minions formally acknowledging the issue 2 hours later at 7am (GMT) via the most official channel available - Twitter. After a few recent updates via the grapevine (companies involved seems to be keeping their heads down at the minute) Ericsson has been fingered for pushing out a wonky software update but there's been no official confirmation of this, so pitchforks away please folks.
If you're in need of a giggle while you wait for your 4G goodness to return, You can always hop on an open WiFi network and read the tales of distress the data-less masses are screaming into the void.6 -
I’m so happy right now, I love doing this. Now just gotta wait for the 10Gbit switch so I can start working on the 150TB storage server solution

This happened sometime back..
A guy came to our university with a social network that he created. It was for students and professors to interact, to form study groups and earn points as they mark done topic as "studied". He made a deal with our university, so everyone was forced to sign up for this.
While he was giving a demo of the website, me and my friend started ranting.
"This website is shit. Why are we forced to use this?"
"This UI looks just like LinkedIn"
"This top bar is right out of bootstrap"
"I have seen that graph in one of the libraries. He didn't even change the defaults."
Another friend who was sitting besides us was hearing all this.
"I don't understand a word you guys are talking. It is too high level for me"
We replied, "Don't worry. We will talk in low level. 00101110010101..."4 -

I just launched a small web service/app. I know this looks like a promo thing, but it's completely non-profit, open source and I'm only in it for the experience. So...
Introducing: https://gol.li
All this little app offers is a personal micro site that lists all your social network profiles. Basically share one link for all your different profiles. And yes, it includes DevRant of course. :)
There's also an iframe template for easy integration into other web apps and for the devs there's a super simple REST GET endpoint for inclusion of the data in your own apps.
The whole thing is on GitHub and I'd be more than happy for any kind of contribution. I'm looking forward to adding features like more personalization, optimizing stuff and fixing things. Also any suggestions on services you'd like see. Pretty much anything that involves a public profile goes.
I know this isn't exactly world changing, but it's just a thing I wanted to do for some time now, getting my own little app out there.9 -

"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.
To find.
That the fucking.
Ethernet cable.
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.

After moving, I don't have DSL yet so I have to use mobile data to get internet access. Additionally I had to finish a freelancing job. In Germany you have one of the most expensive and least reliable mobile networks in europe.
I had to upload my develpoed software to a remote server
So I suddenly was sent back in time. A single call would have disrupted the download (I can't use internet and phone at the same time, might be a phone issue). While my phone has "high speed" volume left and showed at least HSPA, but I still, the upload rate was prehistoric:

The school I went to didn't have PCs when I first joined (had some RISC OS machines instead). They got Windows 95 PCs eventually and networked them. I had no experience with networking before this, but had a PC at home. We all had mapped drives to resources on the server. The PCs were pretty locked down - no "Run" command etc.
Anyway, one day the head of IT came in to one of the lessons and asked me "how I did it".
What had I done? Well, clearly he had seen something I'd taught one of my friends. I wrote it down for him.
1. Right-click the desktop
2. New shortcut
3. \\nameofserver
4. OK
Such hax, being able to see the file shares on the server.
Shortly after this, all computer areas had signs saying "no shortcuts allowed"... -
Managed to make myself look like a fucking moron again today...
Can't mount NFS share, get "permission denied". Huh, that's weird... It's correctly exported.
Well it's correctly exported and rpcinfo -p $HOST times out... Must be firewall rule.
Firewall rule is changed but still no joy "permission denied"... Fuck sake networks, can't you do anything right first time?!!!
Firewall rule is correct I am reliably informed... Go about proving that it's not fucking correct and provide "evidence" to show this, I was a little bit more blunt than was strictly required.
Networks say they will take another look.
I turn NFS logging to verbose for my own interest and notice the line "path/to/directory is not a valid directory".
I, as a moron, had missed a "/" at the start of the path. That's why I still couldn't mount after the firewall change.
Go over and apologise in person and explain how I'm a total idiot. -

I want to know where to begin on my journey on learning how to create a program that predicts what a user will say next by storing already said things and by making specific characteristics for the users.

Customer complains that the deployed desktop app is slow at site x.
I check it out with users at site x, and indeed, it does have a delay when trying to connect to a share on a server.
Checks with users at site y and z, no issues.
After a bit of digging, the resolve of a DNS record is most likely the culprit.
Send the ticket to the customer network team to investigate.
Get it back after an hour.
"We have pinged the DNS name, and it responds fine, there must be a bug in the application".

"Hi, I'm X from the Y office. Do you remember that was you to set up our internal network two months ago? Ok, yesterday we called the elettrician to fix two wall plugs. Now our network is completely broken. Come to fix because we think you did something wrong."
I forced myself into some other jobs i had to do for about 2 hours. After that i grab the smartphone to answer.

I'm reinventing the wheel by making yet another neural network library. It's not any good yet but I learn as I go along.
The only documentation that exists now is the admittedly quite comprehensive code comments. I'm it because Keras (using TensorFlow) requires a 3.5 compute ability rating for CUDA acceleration (which I don't have) and it doesn't support OpenCL. Eventually, I will make my implementation support both with varying levels of acceleration for different compute capabilities with the oldest supported being my hardware. If I ever get around to it.
I'd say wish me luck but determination would be infinitely more useful.2 -
F**king hate Windows for its insanely confusing proxy setup required for software development...
> Setup proxy in Windows network settings
> Then, setup HTTP_PROXY & HTTPS_PROXY environment variable at the system/user level.
> Followed by separate proxy settings for java, maven, docker, git, npm, bower, jspm, eclipse, VS Code, every damn IDE/Editor which downloads plugins...
> On top of everything, find out the domains which does not need to go through proxy and add them to NO_PROXY.. at each level..
> It does not end here. Sometimes, I need to setup proxy for SSH connections... like, if I have to use git with SSH and not HTTP/S... Uhhh....
More than half of the problems me and my dev team face is related to setting the right proxy. Why can't it be like, set in one place and everything picks up from there, like in any linux machine or for God's sake, a Mac ?
Worst of all is, my org uses a configuration script, which resolves into a list of proxy servers, from which one of them will be used. So, I need to download that script, find out which is the right proxy server and then, use it in all the aforesaid places... WTH ?????
Is this a common workplace problem for all developers ??? Will this be solved by Windows Subsystem for Linux ???10 -

Any good alternatives to Twitter? I already know about Gab and Mastodon. What else is there?
By "Twitter Alternative", I mean sites with brief posts, fast member activity, easy to follow users, simple enough to rank in followers, and decent rules.
Note: Tumblr, Reddit, any website builder ever, and any other too well-known social network is not a Twitter alternative.6 -

So I was setting up ELK (Elasticsearch, Logstash and Kibana) all in one EC2 on AWS today for demo purposes. I had everything prepared. Elastic IP, correct security group rules, etc.
I figured I would just do quick test before writing filters and templates if I can access Kibana. So I started service for it and tried to open it with Chrome.
Timeout.
Checked config file. Compared it to documentation. Seemed good but changed some things just for sake of change. Restarted service.
Timeout.
Reverted changes I've made in config. Restarted service. Curl on localhost. It work... OK. 😐
It took me half an hour but finally I figured it out after I took my phone and opened it from there. It was working from the beginning. Stupid company network was for some reason blocking this connection. Fuck! 😡And I was restarting that poor service like crazy trying to fix something that wasn't broken. -
The most crazy issue I've fixed was caused by a TCP behavior which I didn't know, called the "half-closed connection".
There was a third-party application installed on a production server which called a LDAP server for retrieving users information. During the day we had several users using the application and all worked fine. During the night, when the application was not accessed, something happened and the first call to the application in the morning was stuck for about 5 minutes before returning a response. I tried to reproduce the issue in a testing environment without success. Then I discovered that the application and the LDAP server were located on two different networks, with a firewall between them. And firewalls sometimes drop old connections. For this reason network applications usually implement a keep-alive mechanism. Well, the default LDAP Java libraries don't set the keep-alive on their connections. So, I found a library called "libdontdie", which force the keep-alive on the connections. I installed the library on the server, loaded it at the startup and the weird stuck behavior in the morning disappeared.2 -
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.

Since my ISP doesn't allow port forwards on that port, does anyone want to open their port 445 (if not otherwise occupied by Microsoft-DS) and have netcat reply an empty string or so any request (such as an empty string) sent over TCP (or has anyone already done so)? It would help me out a lot with testing out some networks full port range (since portquiz.net's hoster blocks that port) and would take close to no bandwidth for you.6

I just had the idea for a social network which would care about privacy, don't sell the data of its users and stuff. This would mean the users had to pay for it to keep the lights on, like 1 oder 2 bucks a month.

"Hey guys, I have trouble connecting to [Hostname]. I guess it's a firewalling issue would you take a look? Attached are screenshots, saying hostname not found.
Answer:
Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?
Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?
Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!
Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses. -

I currently use Github as my git server and have worked a little bit with Travis. Sadly Travis can't deploy to local network targets and that's why I had the idea to create my own basic CI for the local network: It will be a simple nodejs-app and listens to pushes via Github Webhooks. Then it fetches the code from Github and runs a task runner like Gulp over it and tests it with any nodejs testing framework. Then it deploys the compiled, tested and linted app to the local network. What do you think of this idea?8

Does any one of you own a Omnia Turris (https://omnia.turris.cz/en/)?
In our new apartment, we'll have a 1 Gbps fibre connection (not that we would realy need it, but hey!)
However we need a Router that suports Fibre. The service provider suggested a FRITZ!Box 5490.
I thought about getting the Omnia Turris and run https://pi-hole.net as DHPC on it and maybe add a proxy for TOR or install openHAB later on.

Anyone know private/encrypted p2p network drive app (best would be opensource) between devices in the internet, with multiple user support, invite only ?

Same with other files, on computer can be mounted as network drive.
Or small app with drag drop or cli to add / remove shared directories.
Can be raspberry pi device.
Thinking more, it should work like vpn network but with tunnels between computers.
Can it be done using ipfs ?1 -

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.

So I just installed Elementary OS Loki on my older desktop and for that the wifi is incredibly slow, like 30 seconds to load googles home page. It also randomly stops working, and gives a no network connection. When this system was on windows I would average 50~ mb/s down speed, changing it to Linux I'm lucky to maintain 2mb/s. I've been googling for hours and nothing I try seems to work, any Linux pros here able to give me some suggestions. The network card in the PC is an Aetheros one, I it supports a,b,g,n and Bluetooth, I'm currently using the desktop with a Bluetooth mouse / kbd.

Customer: You don't seem very comfortable with this; maybe you could pass it on to another engineer..?
Situation:
I'm a System Management team engineer. Customer is asking about licensing (which is a different team) and has that very rude habit of asking a question, doing a small pause in which I start answering, and then speaking again and cutting me off; thus causing me to seem very splutter-y. Since I couldn't give a definitive answer to his licensing question he doubts everything and thinks I can't do crap. And he's the one who wants me to sit on an upgrade with him because he's too afraid to follow documentation.
His words to me: "Have you ever done this upgrade before; I mean are you familiar with it?"
Me: "Nope since it's not policy to sit on upgrades as we are a break-fix center but I've directed other customers to do it through the documentation I've given you and they got on fine."
Seriously doubt the capacity of some of these guys to do an upgrade where there's step-by-step videos and very legit documentation (never mind this upgrade uses the tool which has the best record for not breaking)4 -

Our ISP asked if I was satisfied with their service. I told them that it's okay, but some of our computers don't have enough powerful network card, and they can't use the internet on maximum speed, and they said that they could see it, too. WTF? I knew that the ISP's router is not the most secure thing, but it has a remote mode, which if of course OFF, and they still can see this, and maybe even more. Monitoring your traffic is a thing, but a home network should be private...2

Fucking Intel. Only allowing specific SFP transceivers on their x520-da2 card. I gotta load the firmware with a flag to be allowed to use my ubiquti transceivers.

So, something changed at our company not allowing me to connect with the correct network.

Also, in order to work on the application I have to be connected to the company network because our application uses windows authentication, so I keep switching back and forth.1

Not a rant more like a question
Hello devRant,
I am currently planning to purchase a small home server + media client (with Kodi).
A small Linux Distro running the Hometheateroftware Kodi will run on the media clients (Odroid C2). The control is then over an app over the local network. The database of Kodi should be on the server in the form of a MySQL database. The movies, pictures, music are also streamed by the server (max. 2 simultaneously) via SMB (simplest variant). In addition, the server is to be accessible to the outside via a web interface to act as a cloud (maybe nextcloud). The whole should be optimized for stability and longevity. In addition, a small GitLab CE instance will probably run on the server. Do you have any comments or objections? The fact that I only take 2x ne 2 TB hard drive has the simple reason that I currently have no need for more space. Sometimes it happens to me that I forget completely obvious things :D -
I had network problems.. and you know.. no shit.. the problem solve thing which might actually be just a for loop solved it.2

Hi fellow DevRanters! I've been studying software engineering for a while now and, while I love programming, I'm starting to think that all I'll be doing as a software engineer now a days is pulling data from a database, sticking it in a nice gui with some buttons and moving on to the next, similar, project. At the same time I am loving linux more and more, I love working with bash and other unix-like tools and I am interested in systems languages like C and Rust. It is for these reasons that I am playing with the idea of switching to Systems and network engineering. What are your thoughts on this? Is Systems and network engineering a field in which I get to program a lot? Will there be more variation in it? Is my view of software engineering completely off? Please share your thoughts and opinions!2 -

!rant => question?
I'm hired as a freelancer for a start-up that wants to create a social-network-like platform. I've always been a "basic" PHP and javascript developer like using AngularJS, MySQL and my own kinda like PHP MVC framework etc.. But I'm worried that 'this' will come short when the platform expands on the user-base and stuff. That MySQL won't be able to keep up with the expectations and the amountof data, that AngularJS will not be enough for the Frontend,.. I've taken a look at ReactJS, RethinkDB, NodeJS and such, but this is not really within my "comfort zone" and I'm not willing to invest time in something new if it's not able to handle the platform (I don't know if it will..) and I'm afraid that I'll have to start from scratch if it all fails.. (and this is something I can't afford)
So.. What are you guys's opinions? We're not looking at millions of users, but it will have feeds, comments, connections, messages, post scopes,.. Etc. RethinkDB looks promising with the 'watchers' to get live data instantly, but it's a whole new way of query'ing and such.. It just feels like I'm wasting my time because I'm afraid that I'll reach a point in development where I'll have a situation for example like "damn.. This is impossible with angular or php.." [I've shouldn't have agreed to this project..] :D1 -

SMB/CIFS support on Linux distros is a nightmare! Switching from wired to wireless will cause ALL mounts to freeze, and they all become impossible to dismount normally. You can't even ls the root folder anymore if there are frozen mount folders inside. It's f#&%ing retarded to have to reboot your PC twice a day because you lost WiFi signal for one second, and the underlying processes don't understand SIGTERM. And I could go on about MTP! Standard file transfer protocol for Android but boy it is hellish. Trying to copy a structure with subfolders will take forever because every ls call to the phone is like an API call to some free webhosting company in Australia, takes forever, if it even succeeds. I won't even get started on WebDAV and SSHFS (the latter is even worse than CIFS). Those make me want to do unpleasant things to my computer. So frustrating! I can't be the only one who has experienced this, right?1

The day before my lab exam, everyone is busy making copies of C programs that are of eight pages. Some tries to write the copy on paper and some tries to save the previously saved file to another location but before the exam they will clear out all systems in lab.
All systems in lab are connected to an ethernet switch some tries to save a copy to network and that wont work. Finally everyone passed the exam!

Next day i took CMD > msg * location_to_the_program😜 -
