I built a decently large project at work, and everything works perfectly. It's beautiful, it's fast, it's light, it's organized and clean, and deploying is a breeze. I'm very proud of it.
The biggest reason, though, is that it uses exclusively technology I had never touched before:
• React
• Redux
• ES6/Babel
• Webpack
• Express.js
• Material Design
• Apple lappy (I'm a linux girl)
I was completely new to all of these, including my dev machine. Every single aspect of the project was outside my skillet.
But it went from my first experimental `import React from 'react'` to production-ready in three weeks. I'm really proud 😊14 -

!!linux dev lappy recommendations?
So, @Root might finally have a job! Woo!
(Pending a background check, drug test, cavity search, ...)
I'm excited, and kind of giddy. It's an open-office setup, but the devs are chill, the boss is chill (reminds me a bit of myself thus far, just... nice), pay is decent too. Drive is hell, but everything else feels kinda cushy. The parent company is super-stuffy corporate and has an HR and red tape fetish, but supposedly I won't have to interact with them at all. I start as soon as all of the background check nonsense comes through. (Don't get me started on that, please.)
One of the questions that came up, however, is what type of system I wanted to use. I requested a Linux lappy, and that's sadly a bit beyond the parent company's nontechnical IT department. They asked me for links to a few specific machines on amazon for options. (MacBook Pro or equivalent)
That's where this question comes in: Which lappys make great dev machines and also have decent linux (Debian/Mint/Ubuntu) support? The role is backend Rails development + some devops, so I don't need super-fancy graphics, though I will be attaching a 4k (hopefully IPS) display because space and pretty colors.
Recommendations welcome, as I should get back to them today!43 -
Living in a tiny house and having a remote-only job (and no lappy) means I get the wonderful, lovely privilege of working in my bedroom... with my 18mo (who will not leave me alone), and my girlfriend (who won't fucking leave). It's positively great!
Blasting music is often not enough to drown out the sound, and certainly does nothing for getting hit with toys or screamed at to get picked up, so I get basically nothing done during the day. And that's presupposing I'm not begged to run errands/go to lunch with her, both of which take precious hours. (She won't take the baby out alone, so she's always here unless we find a babysitter)
At least it's quiet after 9pm, so I stay up coding for as long as I can. But 18mo's wake up super early, and the girlfriend prefers to stay in the room until I'm up... so even with earplugs I don't get enough sleep. A monster a day and a bottle of Tito's vodka a month is all that keeps me sane.
Why can't I just be fucking left alone to fucking work? I'm our only goddamn source of income.
It's no wonder we're fucking broke.
And to make matters worse, I'm being downsized... and considering the above, I doubt I'll be able to land a new job. 😡15 -
Root rents an office.
Among very few other things, the company I'm renting an office from (Regus) provides wifi, but it isn't even bloody secured. There's a captive portal with a lovely (not.) privacy policy saying they're free to monitor your traffic, but they didn't even bother using WEP, which ofc means everyone else out to the fucking parking lot four floors down can monitor my traffic, too.
Good thing I don't work for a company that handles sensitive data! /s But at least I don't have access to it, or any creds that matter.
So, I've been running my phone's connection through a tor vpn and sharing that with my lappy. It works, provides a little bit of security, but it's slow as crap. GET YOUR SHIT TOGETHER, REGUS.
AND WHILE YOU'RE AT IT, CLEAN THE SHIT OUT OF THE FUCKING BATHROOM FFS.
Ugh. $12/day to work in a freaking wind tunnel (thanks, a/c; you're loud as fuck and barely work), hear other people's phone conversations through two freaking walls, pee in a bathroom that perpetually smells like diarrhea, and allow anyone and everyone within a 50+ meter radius to listen to everything my computer says.
Oh, they also 'forgot' to furnish my office, like they promised. Three freaking times. At least I have a table and chair. 🙄
Desk? What desk?
Fucking hell.20 -
Up for a rollercoaster?
I had a super motivated day where i could focus and wanted to get my work done. My stupid work lappy instead kept throwing tantrums and totally prevented me from working. (Everything caused disk thrashing, took multiple minutes instead of seconds, etc.) Total shit day, but I felt great.
Next morning, I woke up all achy and cold. Ignored it and went to work. I was able to fix everything, and got my benchmarks running smoothly in all of fifteen minutes. Got good results, too! Left work and got married at the courthouse. :)
Went to a restaurant afterward, and two jolly fat guys (Off-duty Santa?!) bought us lunch.
Got home and… started feeling really awful. A little while later, I had a 102*f fever. Collapsed on the floor with an electric blanket and was absolutely miserable. Just kind of stared for hours, aching everywhere. Eventually went to bed, and my wife (!) made me all warm and comfy. And then I proceeded to be completely unable to sleep. Or move. Or think. Laid there for four hours unable to move, and shaking violently at any touch of cold air.
Now it’s 1am and I’m here at the freezing kitchen table writing this.
I am miserable.
Absolutely miserable.
But still happy, too!

So yesterday our team got a new toy. A big ass 4k screen to display some graphs on. Took a while to assemble the stand, hang the TV on that stand, but we got there.
So our site admin gets us a new HDMI cable. Coleague told us his lappy supports huge screens as he used to plug his home TV in his work lappy while WFHing. He grabs that HDMI, plugs one end into the screen, another - into his lappy and
.. nothing...
Windows does not recognize any new devices connected. The screen does not show any signs of any changes. Oh well..
Site IT admin installs all the updates, all the new drivers, upgrades BIOS and gives another try.
Nothing.
So naturally the cable is to blame. The port is working for him at home, so it's sure not port's fault. Also he uses his 2-monitor setup at work, so the port is 100% working!
I'm curious. What if..... While they are busy looking for another cable, I take that first one, plug it into my Linux (pretty much stock LinuxMint installation w/ X) lappy,
3.. 2.. 1..
and my desktop is now on the big ass 4k fat screen.
Folks. Enough bitching about Linux being picky about the hardware and Windows being more user friendly, having PnP and so. I'm not talking about esoteric devices. I'm talking about BAU devices that most of home users are using. A monitor, a printer, a TV screen, a scanner, wireless/usb speaker/mouse/keyboard/etc...
Linux just works. Face it
P.S. today they are still trying to make his lappy work with that TV screen. No luck yet.

Fuck today.
Today I was supposed to go into work and set up a dozen or so units for beta testing (its been a year and a half coming)..
Got up nice and early to get a head start on things. Stubbed (and broke) my motherfucking toe, then spilled my cereal milk on my laptop.. subsequently spend the following 2 hours tearing down and cleaning my poor little lappy. Get her all put back together, starting to feel a little better about the day. Push the power button, and fucking nothing but a tiny little fan noise for half a damn second.
With this luck I don't even want to move, lest a magic falling anvil decides to adorn my head..7 -
Sick.
Worst sleep of my life last night.
Freezing cold, weak, sore, can’t think, starving but can’t eat or drink, as low energy as a dead Chinese “heavy duty” battery.
Finished some changes to my feature today anyway; everything should be done now. Refactored some specs, and got them all to pass.
Falling asleep on my closet floor. Heavy winter coat, fuzzy pants, space heater. It’s warm in here and there’s a shelf for my lappy. Floor is uncomfortable but idc. I’m so tired and out of it I don’t even notice.
This sucks.
At least I have the rest of the week off.21 -
Running a huge migration on our production db.
Takes 45+15 minutes (migration+tests) on my lappy. So. I'm going to be bored and slightly worried for the next hour.
Hopefully the production servers will be faster.7 -
I like playing tf2.
I play every video game with max brightness on the lappy.
The problem is that when I alt tab back to anything else, eg chrome, I get dazzled and my eyes hurt.
I'm on linux and accidentally noticed that I can connect to the X server and do stuff.
So I'm listening for events with the PropertyChangeMask, and when the active window has the name "Team Fortress 2 - OpenGL", I run "light -S 100", otherwise I use what I already had.
Very happy with this hack, instant brightness changes on alt tab. -
I want a case/skin/idk for my lappy after I finally leave this company. I have this awful habit of associating things with memories. If the memory is bad, seeing the object reminds me of it, and e.g. makes me feel burned out again. So, I want to add a really pretty case to my lappy so it feels like my laptop instead of the company's.
I've found a few really beautiful ones on Etsy and Pinterest, but they're so ridiculously expensive! I really don't want to pay $90 🙁
Does anyone know where I can find alternatives?11 -
Tl;dr; even password as simple as 123! Could be too dificult to use for unauth access. Even if you write it down for someone! Some minor HID config changes could be unbeatable for some people.
I always leave my lappy at the office and I leave it turned on and connected so I could connect to it from home if I really need to. The holiday is not an exception. I left it connected too.
Forba few weeks I was trying to connect to it from home to doublecheck xpra command I was using. Without any luck. The lappy was unreachable all this time :/
today some people came in the office. I reached out to one of them I trust the most to check on my lappy. And he says it's charger is unplugged. Fucking janitors...
I ask to plug it back in and turn it on. LUKS password prompt pops up. I send him the pw via sms along with a note that I'm using non-EN kbd layout. He confirms he'll manage.
20 minutes later he pings me "are you sure the pw is correct?". Yes it is! 5 more minutes later he pings me "... Is this how you type numbers and symbols with your layout?" nope, it's the other way around!
10 more minutes later he plugs in his own kbd, still fails. Sets up my layout in his lappy, spends a few minutes using it, plugs it back to my lappy and FINALLY enters the pw correctly.
Come on dude.. 😁2 -
MY LAPTOP just scared the shit out of me. It screamed words like a demon. I thought that I am hacked. But it was just a screen reader... I accidentally activated it or something while unlocking the lappy.2

I've run into my first nVidia driver issues. Ever. ☹
I'm attempting to install the drivers on my shiny new Dell XPS15 8750. It has both an Intel (default) and nVidia graphics card; the Intel works just fine out of the box with Nouveau, with terrible fps. Installing the nVidia drivers causes a conflict with those, and X just displays a black screen. I can still interact via the virtual terminals, but with a 4k display it's kind of annoying.
I'm currently trying to install nvidia-bumblebee and related crap, bur it is not going well.15 -

Saturday. It's already an evening. Kid is asleep. Wife is doing her thing in another room. I'm on my own, I now have time do do whatever I want! So a personal project time it is!
Open up a lappy, wake up my Mint. Switch to a workspace with IntelliJ ide. There's some message popped up on a screen. With a red cross. Read the message -- your licence has expired.
Shit.
Open up chrome, go to jetbrains website, log in, purchase an all-in licence page, filling in the form, last check before confirm... Wait, that ain't right. That's my college email I no longer have access to! Phew, it's a good thing I checked before submitting!
Go to account settings, update my email address, go back to licence purchase form, fill it all in, last check, and...
Wait..
Email hasn't changed. What if they send something valuable to my mailbox upon lic purchase? I can't risk, it's 200€ after all...
Oh come on! Open a support ticket. But it's Saturday so I don't think I'll get a response until Monday :(
and there goes ruined a perfect evening for some coding :(
shit...5 -
Fuck it. It's Friday EOD.
Enough is enough.
It's time to close my lappy and go for a nice long stroll, get all those work thoughts out of my RAM and get ready for two whole days of slacking!!!!
See you next week, suckers!5 -
This freaking laptop.
The WiFi randomly stops working -- and by that, I mean the hardware is no longer detectable, let alone functional. It simply disappears on boot, even from dmesg.
The same happens with audio and bluetooth: on some boots they simply do not exist.
The power usage is also ridiculous: the battery dies in about two hours, and it gets soo hot. Toasty wrists unless I use my tiny bluetooth keyboard ☹ So I need to fiddle with powertop a bit more.
nVidia drivers are also a bloody pain, and having two graphics cards this is even more difficult to set up. I still haven't managed. (nvidia-driver, bumblebee, optimus, official driver messes, manual xorg configs, ...). So I have a beautiful 4k built-in display running at 4-18 fps, and a non-functional 4k external. That's fine for now, but >.>; frustrating.
In better news! I just managed to get the sound to work by backporting the new 4.19 kernel (yay!) -- I have never been so happy to hear an ad. but fixing the sound killed my bluetooth. (The `bluetooth` utility reports the adapter is present, but nothing else can seem to see it 🙄) So now I'm going to have burning hot wrists all day and want to cry because terrible sweaty awfulness.
Just. It's frustrating.
It's fast, though.
and ever so pretty.26 -
My little drawing tablet is finally here! 😁
I have started drawing, but the improvements to my skills are gonna take a loooooooooong time.
Plus, I have a slow and old lappy available now... which freezes in the middle of drawing but oh well! Better than nothing! 🙂 Little improvements matter.
Today was a short exhausting relatively happy day. 🙃12 -
5 stages of failing WIFI connectivity on Linux
This morning I woke up my laptop to start my work day. I have 2 very important meetings today, so I better get all prepared.
"Wifi connection failed"
Syslog says:
- wpa_supplicant: wlp9s0: SME: Trying to authenticate with <MAC>
- kernel: wlp9s0: authenticate with <MAC>
- kernel: wl9s0: send auth to <MAC> (try 1/3)
- kernel: wl9s0: send auth to <MAC> (try 2/3)
- kernel: iwlwifi: Not associated and the session protection is over already...
- kernel: wl9s0: send auth to <MAC> (try 3/3)
- kernel: wl9s0: authentication with <MAC> timed out
#### DENIAL #####
No biggie, let's try another AP (I have 3). All 3 failed to connect. Fine, let's try my phone's hotspot! FAILED!!!!!
w00t.... okay, let's restart the router... but failing to connect to a phone hotspot is already a worrying sign.
Wifi connection failed
wtf.. disable and re-enable wifi
Wifi connection failed
#### ANGER #####
the fuuuuuuck. Maybe my router is dead. But my phone connects to it, no fuss. My personal lappy also connects there easily.
wtf... Does that mean I'm about to lose my uptime?? Come one!! It's Linux - there MUST be something I could do! I don't see processes hanging in D state so the radio must be fine - it's gotta be a software issue!
ChatGPT – type all the log entries manually, via phone (that took a while...). Nothing useful there: update firmware, restart NetworkManager, etc.
#### BARGAINING #####
Alright... How about a USB dongle? Plug it in and wifi connects immediately! Yayyy!!! But that's only b/g/n and I'd very much like to have ac. It works well as a limping backup, but not something I'd use for the meetings.
rfkill block/unblock all the radios. No change. USB dongle connects right away but the PCIe adapter keeps throwing notifications at me with failure messages. It's annoying, to say the least.
So I've already tried
- restarting the router(s)
- disabling/reenabling the radios
- multiple APs
- suspending/waking again several times
- praying
#### DEPRESSION #####
The only thing I haven't tried yet is the most cruel one - restarting the laptop. But that's unfair... It's LINUX! How could it disappoint me. I have so many tmux sessions open, so many unsaved leafpad notes, terminal histories with oh so comfy ^r and ! retriggers all ready and waiting to be executed...
#### ACCEPTANCE #####
But I can't miss the meeting. So I slowly start closing off apps, starting with the least important ones, trying to preserve as much history and recent commands as I can. I'm gonna lose my uptime, that's the inevitable obvious truth... Linux has failed me. Or maybe it's a hardware issue... I can't be sure until I restart.
I must reboot.
#### A NEW HOPE #####
Hold on.. What if... What if before restarting I try to reload the Intel wifi kernel module? Just for the giggles. I've got nothing to lose anyway...
rmmod iwlmvm
rmmod iwlwifi
modprobe iwlwifi
modprobe iwlmvm
*WiFi Connected*
YESSSS!!!!!!!!! My uptime is saved!
403 days and counting! YEAH BABY!!!
Linux is the best!8 -
Current lappy got about 4GB RAM and not enough cores. I can't even run krita without it slowing down more the more I work on a file.
It would be frustrating if only I wasn't so depressed.
So yeah, due to being broke and lack of nerves, I'm gonna completely stop working on the comic for now.22 -
I HAVE A NEW LAPTOP!
and it now has a functioning linux 😁
I fucked it up once tho. I removed the entire network manager by uninstalling bluez. How the fuck, I don't know.7 -
My brother came to me with his phone today to ask me if I could turn it on with my computer, because his power button is broken so I proceeded to attach it to my lappy and boot it with adb just to find out I can't do anything because he hasn't turned on USB debugging!
I managed to get into his recovery which helped nothing because in order to navigate in the menu the power button has to work
Uuuugh I hate this ...39 -
Losing weight (in the particular - belly fat) has an adverse impact on my WFH experience :( I can no longer lay on my back with my legs bent and have my lappy rest on my belly comfortably...
I can't reach the touchpad any more as it's now hiding behind my ribcage :(
I didn't think this through. damn it!39 -
No, this is not a joke/meme.
So I was searching the internet for 2-in-1 laptops -- looking around what could be my next lappy if my current xps13 died. I had a hunch the xps13 convertable is quite overpriced and was looking at lenovo offerings to compare.
This is what one of the largest LT e-shops suggested to buy along with the lappy :)
Dangerous times these are I guess.. Everyone and everything needs protection
[I assume you won't need translation ;) ]

So my car has a problem with a steering column lock. Sometimes the actuator pops an error and it does not unlock until I clear that buggar. Carrying a lappy with vag-com seems somewhat annoying so I got a obdeleven bluetooth dongle with am app.
Once you get it to work it works perfectly. Have been using it for a few years now. It's like a half a year or so since it got a last update and it's been stable as a rock since.
Today me and my fam took a night out with a car. Drove here, drove there, had fun. Time to go home, as the little one is getting sleepy. Got in a car, insert a key, turn it -- no ignition. Damn that steering lock!
So I pop in a dongle, open the app, hit connect,... Wait, what is that? A toast with "a new update is available. [[update now]] [[cancel]]".
Cancel ofc, I need to go home asap! Will gladly get the update when the kiddo is in his bed!
[[cancel]]. The toast disappears. Okay, now [[connect]]
"a new update is available. [[update now]] [[cancel]]"
mother f#$@%!!! Allright already, [[update]] it ffs.
Updated the app. Now [[connect]].
Loading.. Loading... "could not connect to device"
tfq?!?
Reinsert the dongle, connect
restart the app, connect
restart the phone, connect
clear all bt devices, connect
do the rain dance, connect.
Permission to panic: GRANTED.
Dear devs. If you are rolling out an update -- never ever EVER make it non-postponable, non-cancelable. No matter how critical, your updates must NEVER be mandatory.6 -
Soo... Turns out, if your laptop has usb-c charging and it has several such usb-c ports, you can use them simultaneously.
My lappy has issues with usb-c sharging, i.e. it becomes sluggish when charging w/ usbc (compared to on-battery and charging through barrel plug). Aaaaand Linux tends to occasionally crash if I unplug the charger while it's "awake". I wanted to change chargers, so I figured I could plug in the second one (hoping not to see any smoke) and unplug the first one. As soon as I plugged in the second one, all the lag disappeared and the battery keeps charging.
So if you have an usb-c charger that's too weak for your laptop, try using two of them :D
Never would have thought....16 -
Got a 1 day of alone time :) 8 hours WFH ant then the (almost) whole evening was MINE. Guess how it went :)
Coding until 2am and falling asleep on my keyboard, waking up on a cold lappy at 5am bcz its battery died and its aluminium frame was freaking freezing.
I know right? That was an awesome evening! I've managed to catch and fix some nasty bugs!6 -
Here comes the sleep time again. Now I will think about all the amazing stuff that I can build tomorrow and make it big out there just to wake up and do the same thing again and again till I go to sleep and repeat this cycle. Peace.

whhooOOOOOOOOOOOOOSHSHHHHHHHHHHHMMMMMMMMMMMMMRRRRRRRRR
yepp, that's me running a GitLab pipeline on my PC and laptop (laptop is noisier, 'cuz PC has Noctua all over the case).
Turns out running a pipeline of ~200 jobs is quite network-demanding. To the levels where my DNS server in LAN is timing out. And streaming Netflix in parallel kills some of the gitlab runners.
daammnnnn.... I so don't want to pay for an EC2 or EKS at this stage :/
But then again, I don't remember when was the last time I heard fans whooshing in my lappy. I so got used to only hearing the coils whine in it...
Decisions, decisions1 -
When you walk to the yard with a lappy to code some stuff in the nature, smth comes up and you leave your lappy running on a chair for 6+ hours, then finally remember it and it still has >75% juice w/o being suspended.
Sweet!10 -
I really really really need more RAM. 16GB is far from enough. Had to witness the kernel kill all of my Chrome extensions and most of my tabs and an IDE and still it wasn't able to run that container in the 8G RAM it just freed up...
I remember the days when 8G RAM was an overkill.
The times have changed. Now I'm looking into getting a Linux lappy w/ 96GB and still worried whether it'll suffice my needs....7 -
A company weekend in a homestead with a bathhouse and a cold pond.
After a good bathing [~x6 cycles] I'm in my bedroom [left the party early, really want to enjoy the calm and silence]. I thought it would be a good idea to charge my ITware overnight.
Apparently there's only 1 wall socket in the room. And now I have to choose: whether I want an electric heater to basically stay alive until the morning, or a full phone and lappy battery in the morning...
I made the choice

Oh fucking hardware virtualization.
how many times have I failed at setting sth up googled it and just read "check your BIOS ... and enable..."
Well I would IF I FUCKING COULD. THERE AIN'T NOTHING TO ENABLE ON THIS CHEAP CPU.
I know. I know. Should just get a newer setup, this lappy ain't that powerful anyways - but still - it's frustrating to get excited, start sth and than hit that dead end realizing they presupposed sth I don't have.5 -
10 minutes in and I’m in love... my 8 year old windows laptop which was at this point so agonizingly slow it was barely usable, is now lightning fast

so on my new lappy I'm testing XFS. After reading how bloody fast it is, I figured: why not give it a shot!
2 weeks later, I want to go back to ext4. XFS is SSSSOOOOOO fault-intollerant, it breaks my Chrome profile after each forced-poweroff (or power loss). And the on-boot fsck freezes. And after a successful bootup I see the log messages in syslog are all messed up (timestamps are all over the timeline!!!)
it's a mess... A very fast mess.17 -
I decided to run the ROCKYOU password list to see if there are any patterns in md5 hashing, not sure why but I am starting to confuse myself and I need a new pair of eyes to have a look.
in advance, sorry for the shitty image, that lappy is a temporary solution.
So the very accurate and not bias numbers show that the letter "0" appears more than the rest, would there be any use in let's say ordering the wordlist with words that have the most "0" and "7" in their hash to appear at the top?
I believe I might be trying to stretch the numbers and see a pattern where there is none but its worth a shot I think.
Note:
- These numbers come from only about ~14m words
My thinking trail is that if statisticaly these hashes are more likely to appear, they are more likely to be the one I am looking for?

Anyone recalls my raspberry's hotfix for overheating problem?
Frankly I am considering it as a long-term solution. I currently have a proper rpi fan applied but it's just too freaking noisy! I thought my work lappy is noisy when at 90C. But this tiny rpi fan is just.. Painfully loud! Especially when rpi is suppised to be tiny and invisible.
Soo.. Yeah.. 3"" fan for an rpi it is!9 -

Batteries don't like me anymore
Yesterday late evening I was out to bring a festive parcel to someone. I left home with 29% batt, went there and still had 27%. Made 3 short (~1min) calls and headed home. Opened Firefox and my phone crashed. WTF, how could FF crash Android? OS separation failure? I turn my phone back on and it says LOW BATTERY: 0%. wtf... With 27% I should have been good until the next morning with no problems! And now it went 27%→0% in a blink (literally).
Today I decided to stay on my lappy for the morning. YT videos to catch up to, dR posts to scroll through, etc. A few hours later laptop battery is drained down to 29%. I step away for a few minutes for a cup of coffee and when I come back - the battery indicator LED is glowing amber and OS says it's got 6% left
29%→6% in a few moments of idle. Riigghhhhttt.... And I thought I won't want anything for this Christmas.
I wonder what's the significance of 27/29% there...3 -
## Learning k8s
Okay, that's kind of obvious, I just have no idea why I didn't think of it..
I've made a cluster out of a rpi, a i7 PC and a dell xps lappy. Lappy is a master and the other two are worker nodes.
I've noticed that the rpi tends to hardly ever run any of my pods. It's only got 3 of them assigned and neither of them work. They all say: "Back-off restarting failed container" as a sole message in pod's description and the log only says 'standard_init_linux.go:211: exec user process caused "exec format error"' - also the only entry.
Tried running the same image locally on the XPS, via docker run -- works flawlessly (apart from being detached from the cluster of other instances).
Tried to redeploy k8s.yaml -- still raspberry keeps failing.
wtf...
And then it came to me. Wait.. You idiot.. Now ssh to that rpi and run that container manually. Et voila! "docker: no matching manifest for linux/arm/v7 in the manifest list entries."
IDK whether it's lack of sleep or what, but I have missed the obvious -- while docker IS cross-platform, it's not a VM and it does not change the instructions' set supported by the node's cpu. Effectively meaning that the dockerized app is not guaranteed to work on any platform there is!
Shit. I'll have to assemble my own image I guess. It sucks, since I'll have to use CentOS, which is oh-so-heavy compared to Alpine :( Since one of the dependencies does not run well there..
Shit.
Learning k8s is sometimes so frustrating :)2 -
Fucking windows updates...
Went to do a job on a tank in 18 deg F Weather with snow on the ground. One guy brought an ice fishing tent (very nice). This is next to petroleum tank. We got guys on top of tank waiting for me to get data using a Windows 10 lappy.
Lappy comes up and tries to get into bios to do a firmware update. WTF! I reboot and it does it again! Go to look for power adapter as it wont do update without power. Not in bag. It has to have power to do update.
So I drive back to shop (with guys waiting on top of tank) which is 5 miles away. I am pissed. Its snowing and I have to drive slow. I find that adapter. I get back to the tank and plug it in. The AC source (battery based) starts alarming as the lappy takes too much power. Fuck! But somehow it boots Windows without doing firmware update. Fuck you Windows!
I get my job done, but don't fucking trust windows at all. Had this been a field tech he would be pissing his pants. Useless shitty software you have zero control over. Now considering changing their OS to Linux for field work. I am rewriting their software anyway with something can run Windows or Linux.4 -
Place to code:
Wherever I get place to make a V shaped stand for my lappy with my legs and stomach.6 -
Oh shit... My XPS 13 seems to slowly approach it's EOL :(
It has lost power 3 times already since yesterday. The last time it shut down while I was browsing BIOS (UEFI) settings, on a charger...
shit :(
Yes, I am drooling at the new XPS 7390 with advertised battery lifetime of 21 hour. But I'm so used to my lappy.
Shit :(9 -
## Learning k8s
Interesting. So sometimes k8s network goes down. Apparently it's a pitfall that has been logged with vendor but not yet fixed. If on either of the nodes networking service is restarted (i.e. you connect to VPN, plug in an USB wifi dongle, etc..) -- you will lose the flannel.1 interface. As a result you will NOT be able to use kube-dns (because it's unreachable) not will you access ClusterIPs on other nodes. Deleting flannel and allowing it to restart on control place brings it back to operational.
And yet another note.. If you're making a k8s cluster at home and you are planning to control it via your lappy -- DO NOT set up control plane on your lappy :) If you are away from home you'll have a hard time connecting back to your cluster.
A raspberry pi ir perfectly enough for a control place. And when you are away with your lappy, ssh'ing home and setting up a few iptables DNATs will do the trick
netikras@netikras-xps:~/skriptai/bin$ cat fw_kubeadm
#!/bin/bash
FW_LOCAL_IP=127.0.0.15
FW_PORT=6443
FW_PORT_INTERMED=16443
MASTER_IP=192.168.1.15
MASTER_USER=pi
FW_RULE="OUTPUT -d ${MASTER_IP} -p tcp -j DNAT --to-destination ${FW_LOCAL_IP}"
sudo iptables -t nat -A ${FW_RULE}
ssh home -p 4522 -l netikras -tt \
-L ${FW_LOCAL_IP}:${FW_PORT}:${FW_LOCAL_IP}:${FW_PORT_INTERMED} \
ssh ${MASTER_IP} -l ${MASTER_USER} -tt \
-L ${FW_LOCAL_IP}:${FW_PORT_INTERMED}:${FW_LOCAL_IP}:${FW_PORT} \
/bin/bash
# 'echo "Tunnel is open. Disconnect from this SSH session to close the tunnel and remove NAT rules" ; bash'
sudo iptables -t nat -D ${FW_RULE}
And ofc copy control plane's ~/.kube to your lappy :)3 -
Any Hackintosh users in here? Got any setup pics to share? I'm thinking about setting a second partition to get in the game again with High Sierra, since I haven't used macOS since Yosemite. Windows 10 won't let me change my main on my desktop and my lappy is too happy with its Ubuntu LTS.

why won't you people let me move on ?
you people started draining me of my life a little at a time from the age 28 onwards. why ? I just want to see some goddamn new tv and movies and work and have a home, and an acceptable level of progress in life.
a chick once and awhile, some lappy dances, and a stiff drink twice a week.
why is being an actual standard american such a horrible prospect for so many miserable little evil bastards out there ?1 -
what the f....
So I'm making some changes to my setup. I'm relieving my current router from its duties and retiring it as a mini PC for my desktop setup. And I got my hands on a Dell Optiplex that will become my new router.
Now, firstly, the Optiplex came w/o a wifi antenna. I booted it up into a LinuxMint install USB for the first time and didn't expect much from it, but to my surprise, I got a popup: "There are wifi networks available". At that spot there was also my Fenvi PCI wifi card's antenna of my current (soon-to-be-previous) PC and it was barely seeing any wifi, and there came Optiplex with NO antenna attached to it and it managed to maintain stronger and more stable signal. wtf....
Alright, it's Fenvi, it's chinese -- there's probably not much I should expect from it.
Then I hooked it up right next to my current router with an external USB wifi adapter having 4x6dBi antennas on it, serving as my current wifi AP. Trying out hostapd configs, searching for the right channels,... should I test it? Naah, it still doesn't have an antenna - it won't reach my laptop. Meeh, for shits and giggles! `hostapd -d /etc/hostapd/hostapd_custom.conf`, on my lappy `nmcli d wifi rescan; sleep 5; nmcli d wifi` and... wtf... To my surprise, the AP was there! A thick wall away, no antenna whatsoever, and I still could connect to that Optiplex AP and post this rant!
What magic is this??? I'm now a bit concerned about ordering an antenna for it - I'm worried it could either worsen the signal or make it so strong that it'll fry my brains overnight.4 -
I have a nice laptop already. Yet I see this and want it. It is about what I paid for my current lappy. The nice part is more ram, more cores, and a 2060 gfx. Right now I am running a 1650 gfx.
I just don't have a "good" reason to get this. I am glad lappy prices have finally gotten near normal again.
Anybody have experience with the newer AMD processors? Worth it?

HP
I really like their laptops, or i used to. My HP lappy has a realtek WiFi card and realtek doesn't provide support for Linux. I think I also hate realtek. Furthermore, my laptop starts throttling because of dust being collected. Some people that I know have older Dell laptops that work better than mine1 -
old one stuff...
Bought lappy with AMD processor
getting hot a lot and fan sound too much
after checking got to know about #PowerNow option in Bios
.
.
turned it off now and finally
No more heating no more fan speed
Looks like it was meant to be disabled but enabled unknowingly...
Hahhah
