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 😊

!!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!

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.

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.

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!

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....

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

I REALLY wanna install Linux on my main lappy but I’m too skittish about losing my music production stuff

## 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 :)

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.

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 mine
