So at work today my coworker overlooked my laptop running Linux with i3.

Coworker: How do you live with this?

Me: What do you mean? This is customized to work with Git and my IDE efficiently while I do dev ops with my server.

Coworker: Your mouse barely works and you operate this thing totally on keyboard shortcuts. Linux will never be a serious platform.

Me: I'm not saying you or anyone at work has to use this, I built an environment to suite my needs. Same as anyone. I thought you liked consumer choice?

Needless to say we didn't get much further beyond him thinking I was nuts for configuring my server in the cli. I swear I don't understand why I try to explain anymore. 😡

Not sure what Linux Desktop to use? Use this handy guide:

- GNOME: when you want no tray icons, themes that break every minor GTK release, and extensions for basic features (that are buggy.)
- KDE: pretty go-Segmentation Fault
- DWM/Awesome/i3/etc.: when you feel like the time you spent learning Vim wasn't wasteful enough
- XFCE: when you want one update per decade and poor Systemd support.
- LXQt: the biggest positive is that it doesn't use GTK.
- Cinnamon: when you like GNOME 3 but you want a different menu
- Deepin: when you want a desktop with the build quality of an HP laptop.

Aren't sure whether to use Xorg or Wayland?

- Xorg: if you want to absurdly fuck up your touchscreen, pick this one.
- Wayland: if you want to screw up most of your apps, too bad; this won't work with your proprietary drivers. If only it did.

What distro to use?

- Ubuntu: if you want to break your system with PPAs, check out this one.
- Debian: when you want Ubuntu except with more out of date packages
- Redhat: when you want Debian except with more out of date packages
- ElementaryOS: wait, someone actually made a properly designed Linux UI?
- Arch Linux: the only thing that doesn't make me sick anymore.
- Slackware: "that exists still really?"
- Gentoo: when you hate systemd more than waiting 4 days to compile Firefox on every release.

... I love Linux. I do. But it is very taxing to get things comfortable for me anymore. I feel like the Linux Desktop is in a period of flux and it's painful to be a part of right now.

So I cracked prime factorization. For real.

I can factor a 1024 bit product in 11hours on an i3.
No GPU acceleration, no massive memory overhead. Probably a lot faster with parallel computation on a better cpu, or even on a gpu.

4096 bits in 97-98 hours.

Verifiable. Not shitting you. My hearts beating out of my fucking chest. Maybe it was an act of god, I don't know, but it works.

What should I do with it?

POSTMORTEM

"4096 bit ~ 96 hours is what he said.

IDK why, but when he took the challenge, he posted that it'd take 36 hours"

As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"

I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths

@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.

Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.

What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.

This started cropping up, ironically, right after I posted the thread, whats a man to do?

So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.

Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.

For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.

So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)

x = a/p
y = b/p

1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.

2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.

3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.

Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.

Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.

Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.

I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.

The final result in executable pseudo code (python lol) looks something like the above variables plus

while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i

Still working but if anyone sees obvious problems I'd LOVE to hear about it.

Antergos with KDE is so beautiful 😍😍
It is so customizable, something which I always missed in elementary.

Why people keep installing shit on their computers and then asks me if I can fix their PC that "randomly" stopped to run as fast as before?

If you, fucking retard, installed combos of 2 or sometimes even 3 antivirues, the worst ones by the way (e.g. Avast + Norton + Avira), some bullshit utilites like BoostMyFuckingPC 9000, SpeedMyGPU, etc. it's normal that it doesn't work, especially if you have a low end laptop with Intel i3 and 4 GB of RAM…

And it's not true I'm a magician if I make it work properly again, I just undone the fucking decisions you made when you started to search on bing how to increase FPS in LoL…

Fuck you, and fuck me because since we're friends/relatives I HAVE to help you little bastard.

Me, starting my internship in ML.. coworkers come to me asking what computer I need:
Me: Well, something more powerful than this i3, and most importantly some kind of GPU for training.
Them: Ok, what kind of GPU?
Me: Well, a 1080 or 2080 should be more than enough and good performance for the price.
Them: Oh.. We were more thinking about a Tesla V100 or something like that!
Me: (internally) WTF this costs more than what you'll pay me for the internship, this is so cool. (to them) Oh, yes, why not, great perfomance, blah blah blah.

I would prefer them to pay me more, but at least they're not going to hold me down with bad components! Nothing to rant about for now.. Hope it'll stay the same ^^

1. Slack. Pretty good chat app for dev companies, I use it to prevent people standing next to my desk 40 times a day.

2. Unit testing tools, especially when fully automated using a git master branch hook, something like codeship/jenkins, and a deployment service.

3. Jetbrains IDEs. I love Vim, but Jetbrains makes theming, autocompleting & code style checks with mixed templating languages a breeze.

4. Urxvt terminal. It's a bit of work at the start, but so extremely fast and customizable.

5. Cinnamon or i3. Not really dev tools, but both make it easy to organize many windows.

6. A smart production bug logger. I tend to use Bugsnag, Rollbar or Sentry.

7. A good coffee machine. Preferably some high pressure espresso maker which costs more than the CEO's car, using organic fairtrade hipster beans with a picture of a laughing south american farmer. And don't you dare fuck it up with sugar.

8. Some high quality bars of chocolate. Not to consume yourself, but to offer to coworkers while they wait for you to fix a broken deploy. The importance of office politics is not to be underestimated.

One of those things that put a smile on my face happened today.

I (like many devs) am fond of Linux. So I use Linux on everything.

I'm currently doing an internship abroad in Finland(Linus Torvald's country!) for my college.

So there is this Finnish student who uses Linux. And after a while he asked what I was using so I told him that I'm running linux(arch+i3 like all the cool kids).

So one day he was like; But can you game on Linux?
I was like, yeah sure, might not work as well as Windows but some games run native and some can be emulated through wine. He was like; Hmm maybe I'll try it out.

So he installed Linux mint on his laptop and came to work. I was rather proud (even though he installed the bastard child of Debian and Ubuntu).

So far I've helped him set up streaming games from his pc to Linux and port forwarding.

But then came the big boy. Since I always try to teach him some stuff since they don't teach him a lot at his school.

He asked me if I could help him set up a plex streaming server on Linux.

So we took an old computer and installed Ubuntu Server(Lot's of information for it).

Installed and configured plex server, qtbittorrent-knox and all kind of goodies.

I started showing him how to use ssh, how the rights system works, etc.

It broke my heart a little that he want to be able to teamviewer in it.(since it's running openSSH daemon)

So he installed Ubuntu's desktop ontop of it as well as teamviewer.

It ran slow as hell because the PC has an old crummy core2duo and ddr2 2gb of ram. It chokes when multitasking.

So seeing that as well as telling him everything that can be done with a GUI can be done in CLI.

I saw the lightbulb lighting up. He gets it now. He understand the power of Linux.

That just made me smile all the way home.

Less rant, more mildly interesting Java trivia.

Integer i0 = 3; Integer i1 = 3;
Integer i2 = 300; Integer i3 = 300;

i0 == i1 is true as expected
i2 == i3 is actually false

Java caches -128 to 127 Integer objects for faster perf so when you're inside that range, the objects are indeed the same, but because == checks object equality, the Integer outside of the range is not cached and had to be initialized, so i2 and i3 are two different objects.

You can totally break some tests this way :)

Me:
*spins up Vscode*
*spins up postman*
*opens terminal, spins up docker*
*spins up frontend dev server*
*spins up backend dev server*
*opens new chrome window with not less than 20 tabs*

My 4year old 8gb RAM Core-i3 PC (barely fighting for her life):

Holy fuck...I didn't expect this.
simple terminal from suckless.org
(aka. st) After appiled path "alpha" -> It did transperent in the way that if you have 2 terminal overlaps -> It'll draw a transperent surface with the underline terminal. so, It's not an idea for open vim with i3 tab or stack mode. I kinda gave up on using it until I realize -> what if underline terminal is "mpv" which is video player. This is a result (Holy fuck is awesome). by set "hi Normal ctermbg=NONE" in vimrc to make transperent background with vim.
Now, I have "mps-youtube" which allow me to watch youtube with mpv, basicly (vim + youtube) as the same time.
ps. If gif is not play -> tell me, I'll upload video. (seriously, is awesome)

So... a lot of people is uploading their setups .s
Here is mine. Its not so well but i get on well with it :3

It has got 8gigs of 2400 mhz ram
A gtx 1050ti
1 tb hdd
I3 7100
Can anyone recommend me a headset bc mine is kinda trash.

Here is my home setup (I mainly work at home)
Left monitor is for my windows machine, right monitor swaps between my laptop and my PC (depends if I am working or not) laptop running Manjaro with i3 and the tablet on the whiteboard will be used for some monitoring in the future

Don't mind the terrible cable management behind the table :)

So, 2 weeks ago, some guy in here left a comment about how great i3 is, so I was curious and installed it.

Since then I spend the same amount of time on playing with i3 as on doing actual work. Not sure if I love or hate that guy, but i3 really is awesome.

This is a guide for technology noobies who wants to buy a laptop but have no idea what the SPECS are meaning.

1. Brand
If you like Apple, and love their !sleek design, go to the nearest Apple store and tell them "I want to buy one. Recommendations?"
If you don't like Apple, well, buy anything that fits you. Read more below.

2. Size
There are 11~15 inches, weight is 850g ~ 2+kg. Very many options. Buy whatever you like.

//Fun part coming

3. CPU
This is the power of the brain.
For example,
Pentium is Elementary Schoolers
i3 is Middle Schoolers
i5 is High Schoolers
i7 is University People

Dual-core is 2 people
Quad-core is 4 people

Quiz! What is i5 Dual-core?
A) 2 High Schoolers.

Easy peasy, right?

Now if you have a smartphone and ONLY use Messaging, Phone, and Whatsapp (lol), you can buy Pentium laptops.
If not, I recommend at least i3

Also, there are numbers behind those CPU, like i3-6100
6 means 6th generaton.
If the numbers are bigger, it is the most recent generation.

Think of 6xxx as Stone age people
7xxx as Bronze age people
8xxx as Iron age people
and so one.

4. RAM
This is the size of the desk.
There are 4GB, 8GB, 16GB, 32GB, and so one.
Think of 4GB as small desk to only put one book on it.
8GB as a desk to put a laptop with a keyboard and a mouse.
16GB as a normal sized desk to put some books, laptop, and food.
32GB as a boss sized desk.
And so one.

When you do multitasking, and the desk is too small...
You don't feel comfortable right?
It is good when there are spacious space.
Same with RAM.

But when the desk becomes larger, it gets expensive, so buy the one with the affordable price.

If you watch some YouTube videos in Chrome and do some document words with Office, buy at least 8GB. 16GB is recommended.

5. HDD/SSD
You take out the stuffs such as books and laptop from the basket (HDD/SSD), and put in your desk (RAM).

There are two kinds of baskets.
The super big ones, but because it is so big, it is bulky and hard to get stuffs out of the basket. But it is cheap. (HDD)
There are a bit smaller ones but expensive compared to the HDD, it is called SSD. This basket is right next to you, and it is super easy to get stuffs out of this basket. The opening time is faster as well.

SSDs were expensive, but as times go, it gets bigger as well, and cheaper. So most laptops are SSD these days.
There are 128GB, 256GB, 512GB, and 1024GB(=1TB), and so one. You can buy what you want. Recommend 256GB for normal use.
Game guy? At least 512GB.

6. Graphics
It is the eyesight.
Most computers doesn't have dedicated graphics card, it comes with the CPU. Intel CPUs has CPU + graphics, but the graphics powered by Intel isn't that good.
But NVIDIA graphics cards are great. Recommended for gamers. But it is a bit more expensive.

So TL;DR

Buying a laptop is
- Pick the person and the person's clothes (brand and design)
- Pick the space for the person to stay (RAM, SSD/HDD)
- Pick how smart they are (CPU)
- Pick how many (Core)
- Pick the generation (6xxx, 7xxx ....)
- Pick their eyesight (graphics)

And that's pretty much it.
Super easy to buy a laptop right?

If you have suggestions or questions, make sure to leave a comment, upvote this rant, and share to your friends!

Fuck, I did not know it was possible to wait this long for something to boot up. Too scared to even install Visual Studio.

Downgrading from my own i7 pc with 16GB ram and an ssd to a company i3 budget laptop with 4GB ram and 5400rpm HDD.

Could never understand all this bitching about Windows 10 and how it is shit slow, but I have come to realize what everybody has been complaining about.

woooooohoooooo! successfully installed Gentoo on my laptop after 7 hours of compilation. It's probably not in the perfect state as I'd like, but I hope to work it out.
My current problem...
WHY can't i have separate DPI's on different displays!!!!
I can't use my second monitor right now because of DPI issues.

BTW, i configured Gentoo + i3

For now, i'll sleep sound 😅😅😊😊😊

So I gave i3 a try today via Manjaro i3 (don't have time to get a config of my own from scratch, would rather have a working setup which I can fiddle around with).

It's pretty...good actually. Doesn't work quite as well as I'd hoped because of my laptop's small screen, but still nice. Works well with my Blender and editing workflow too, so that's a plus.

After I'd spent an hour fixing audio and WiFi issues, of course, because Linux, but then that's just part of the fun amirite

I've decided to change the key components of my Arch Linux system. Of course it's not gonna be quick but here's my plan:

i3 -> bspwm
VSCode -> GNU Emacs

What do you guys think?

Aaaah FUUUUUUCK!!!!!

As if I had nothing better to not nor deadlines I went on a mission to tweek my i3-wm installation with resulted in lightdm not starting... FML

When you upgrade to awesome 4.1 and have to weed through and refactor 863 lines of Lua (not including theme file) -_- i3 is looking pretty good right about now

!rant && story

tl;dr I lost my path, learned to a lot about linux and found true love.

So because of the recent news about wpa2, I thought about learning to do some things network penetration with kali. My roommate and I took an old 8gb usb and turned it into a bootable usb with persistent storage. Maybe not the best choice, but atleast we know how to do that now.

Anyway, we started with a kali.iso from 2015, because we thought it would be faster than downloading it with a 150kpbs connection. Learned a lot from that mistake while waiting apt-get update/upgrade.

Next day I got access to some faster connection, downloaded a new release build and put the 2015 version out it's misery. Finally some signs of progress. But that was not enough. We wanted more. We (well atleast I) wanted to try i3, because one of my friends showed me to /r/unixporn (btw, pornhub is deprecated now). So after researching what i3 is, what a wm is AND what a dm is, we replaced gdm3 with lightdm and set i3 as standard wm. With the user guide on an other screen we started playing with i3. Apparently heaven is written with two characters only. Now I want to free myself from windows and have linux (Maybe arch) as my main system, but for now we continue to use thus kali usb to learn about how to set uo a nice desktop environment. Wait, why did we choose to install kali? 😂

I feel kinda sorry for that, but I want to experiment on there before until I feel confident. (Please hit me up with tips about i3)

Still gotta use Windows as a subsystem for gaming. 😥

Im gonna get a new laptop soon and on my old laptop I want to install linux (cant do that on my main laptop because Im a windows dev at the moment).

I am not new to linux and have used 3 major ubuntu versions and it was all trouble, autoremoving files after update etc.
So I am planning to go Manjaro but which desktop environment shall I use? I've heard great things about i3 and Cinnamon. Gnome is not something I liked in Ubuntu.

Which desktop environment do you use, why and how did you make the choice?

Just finished setting up my new mobile workstation (not a desktop killer unfortunately).
Have i3 booted on a chroot and configured and ready to get cracking for the night :D

Been trying to install myself a gentoo but it's been more like the mode of broken packages than the godmode of Linux... I mean I see that some packages break if I am trying to compile via musl (not fully supported yet) or via uclibc. But please. CAN'T YOU JUST FUCKING TEST THE PACKAGES BEFORE PUSHING TO LIVE? Seriously. I just wanna install a system with i3 and lightdm for the first. But do you think I could build even the first 20 packages WITHOUT A FUCKING ERROR MESSAGE?! FUCK NO. I mean it's a clean install - nothing should be blocking - let's wait a day.
*one day later*
Fuck. Shit doesn't work now either.
*gets himself a new tarball*
Wow now it works.... Or not. 4 packages later it failed again. And like that it continues.
Gentoo isn't even running on that new software. BUT IT STILL WON'T BUILD ANYTHING TO EVEN LET ME CONTINUE BUILDING A FUCKING KERNEL AND SETTING THAT SHIT UP.
Now I am totally frustrated - deleted my efivars once because I forgot to unmount /sys from the Chroot - after a few days of trying. I tell myself: Why not just arch? It always worked.
Okay then reboot to windows and get an arch-livesystem.... If only my Windows didn't boot entry disappear again.

Didn’t touch to my arch usb install in a month (didn’t have to use it)

Ran pacman -syu.

The Internet connection is not fast, it’s been ongoing for 1 hour and will probably last for another.

i3 semicrashed, can’t close/run programs, can’t do anything.

Anyway, just wasting my time on here.

Listening to “thoughts and prayers” from grandson because of santa fe:
May their gods be with them and their families and their friends. I wish the best of recovery for the ones wounded, physically and mentally.

And for the shooter:

Take a trip to the hell of js frameworks and just stay there, 🖕you for what you did! You’re a twisted tomato burried deep in the fucking ground of sadness and horror jambled with middle fingers crooked by bullets shot from your gut and mind.

So my laptop broke recently, and I've been looking for a replacement, but everything is so expensive.

I was thinking of just buying something really lightweight for like 100 - 200 $, then putting linux on it (no gui) and running everything through the terminal. I basically want to be able to work on github projects with, maybe use minimal internet.

Vim + git is all i use for github projects anyways, and lynx would let me do the small amount of internet that i want.

My one concern is that itd be very nice to have a window manager (terminator, i3, etc), not sure exactly how that would work with no gui.

Any thoughts on this setup overall? Or specifically the wm part?

Archbang, Archlabs or Manjaro?
I am interested in using i3 as my wm. And because I will install it in my daily driver laptop, I want it to be reasonably stable and not with breaking updates.
Any thoughts and / or recommendations?

No no no, that's not for what I came to linux.
Opened couple of tasks including one browser with < 10 tabs, sublime, skype and it starts fucking hang.
I have 8g ram, core i3 .
I'm using Ubuntu 16 lts. Its such a shame

Are here Vim users using the dvorak layout?

I am thinking of learning (programmer) dvorak but I am way to comfortable with Vim. I think Vim itself would not even be my primary concern since one should not use HJKL anyway. But I also have these bindings for switching tmux panes, vim splits and windows in i3, etc .
I think Dvorak would be a great opportunity to finally learn touch typing but I fear that Vim is not compatible with it.

So what is your experience with these two? Does it work? Is it worth it?

Spending six hours installing Antergos and reinstalling Antergos because I can not log into my laptop when I install i3 nor when I install GNOME...

Turns out the drivers for NVIDIA got installed (I checked it without thinking about it) everytime and that was the culprit...

Lesson learned: install everything by yourself, that way you know what you have on your laptop, and makes it much easier to troubleshoot..

Recommendations for customizing vim & i3 for programming workflow?
Do you have any settings/plugins you prefer?
Also, any nice ideas for compiling latex docs while writing it in vim? Like a side by side thing maybe, not really looking for ide.

Hi,
I want to install linux besides windows on my new computer (i7-8700k, gtx 1080). I use debian with i3 on my laptop for work and want to have a similar development environment at home. Does anyone have an adive to choose between ElementaryOS and Arch, or just stick with Debian. i3-gaps will be the wm, I just can't use another one ;)
Does one distro has better support for Nvidia cards in fact I would like to try CUDA.
I do not have other requirements; mostly webdev with python in the backend, and a little c++ game with SDL. This should not be a problem in a new distro.

Thanks for some advices and pro/cons

A follow up.. Changed my monitor... (not better than what I had) was just boared... Then Ibsaw my desktop (Gnome) and wanted to change it to. So i started removing tons of gnome and ubuntu packages including gdm and stuff.. Installes i3. started configuring... installed a dm... Changed my idea and started to install a new distro to start from scratch.. Spent a day like this. have absolutely no reason to do this.

Fucking Matlab ><'
I can't get the fucking thing running on my Linux install. Took me 3hrs to install it, and now the fucking fonts won't show
i3 and Matlab do NOT go well together...

C- let's See
C is a procedurally developed language follows sequential method of solving a problem.
Example
If a teacher of an Institute teaching various subjects, Maths, English, Science and History.
Case1.One student comes and asks teacher to teach English
and next student to teach Maths,
And the other to teach History.
Case2.Next students comes for English
Case3.Other one for History.

So what I understood regarding C is procedural language is
It completes first case1,next case2, and then case3. (Task after task)
Here English is taught 2 times seperate
And History too 2 times separately making time and process complexity.

C is a platform based high level language support only desired platform. If I program in windows with i3 processor , it runs only on the same OS and Processor, if code is run in other computers.
Single threaded, if a code is interrupted in between, stops there and doesn't allow other part of the code to run.

Java
In this if the same above cases encountered then and tell
Computer to create a Class of English and tell all the students to attend the class(time saving, No complexity and not repetitive)
Same way Creating History class and make all students attend the class at once.
Students may be the objects created.
Multi threaded language, if a task is interrupted following code cannot be stopped. Allows other part of thecode to run.

JVM- Java virtual machine allows Java code into signs that can be understood by computer. Where as C converts into binary code.

A class concept added to C language become C++

Things that wasted my time this week:
bash in my .cshrc
Using the wrong application to open waves.
Logs after an if(a thing) return;
Updating i3-gaps and using my config and it locking up.
A testing machine having the wrong kernel as default.
Not a bad week :)

I'm wondering how you guys can use a laptop with keyboard that lacks something as crucial as numpad. Was it hard to get used to not having it? I'd love to replace my old Samsung Ativ Book 2 (that monstrous i3...) for a Dell XPS or something similar but seeing that it hasn't a numpad makes me wanna cry.
I'd love to hear from you, how is your experience without numpad and how long did it take to get used to.
