Rant...ish? It's more mixed feelings...
Had my first day yesterday at a new job in a big company. I came dressed really nicely in a suit and tie. Went to orientation with everyone new coming in.
Felt like I made the right choice to up my effort in dress code.
Met with my manager, was led to my team. Everyone is dressed casually. Unshaved. Giving me hate stares.
Felt out of place. But kind of happy that I can try less.
Still. What's up with programmers and being toxic to people dressed nicely o.0 I don't need to look like I came out of crunch time every single day to prove my worth...
It's really weird getting these looks. It's almost like highschool all over again. When I let my mother dress me and looked like the nerdiest kid on the block...
Then again, today I'm wearing sneakers and causal clothes. I either feel like I cave in to peer pressure... But at the same time I don't mind it. Erghhh... Still hate this...
Mixed feelings... I donno.7
On the topic of mesh networks
1. Anyone know of a good non-cloud dependent mesh network system under $300?
2. Anyone every attempted to setup their own with libremesh or with prototype-cjdns-pi?1
Any people using Julia here for something real. Like analysis or building applications? Is it worth learning or should I stick to python and cpp ?3
I love pipes in R. Really wish more mainstream languages would adopt that *looking at you python, nodejs-tc39, rust, cpp*
Just something about doing
data %>% group_by(age) %>% summarize ( count= n() ) %>% print
As oppose to
print(summarize (group_by(data, age), count=n()) )19
Anyone ever bought a laptop from ststem76 or from purism? I'm looking for a good laptop for development and gaming. (I'm a Linux fanatic btw)7
Is it ethical to charge a client for the runtime of a computation? I.e. cpu time?
I usually don't, since it doesn't cost me anything to leave my machine running overnight. But a few of my friends told me that I should.
I do sometimes freelance work for professors as an RA. At times you need to leave a script running for like +5 hours. During which I just either procrastinate or go to the gym or sleep. The energy cost for computer running is barely a dollar.
I get charged by the hour per work in my timesheet, or sometime for a negotiate price which is also usually computed by the estimated work time it would take.5
1. Building stuff is awesome!
2. It's creative work that actually makes cash
3. I like writing algos and math4
Worst part about getting a new laptop: losing all my stickers
Best part of getting a new laptop: New Stickers!1
I really regret switching to manjaro. So many things keep breaking, like my laptop won't sleep anymore, it stays up, whenever I plug in another display I get an error thrown at me. Among other weird behaviors (all screen related) that I can't seem to fix and make the experience feel like I'm running a very clunky win-poop machine.
On the other hand, setting up a very custom sddm theme and installing certain software like hadoop, rust, gimp, xfce tweaks and other things was such a breeze D: just "yay hadoop" and 90% of the work was done.
Grhhh... Wondering if I should accept defeat, and maybe switch to Linux MX or spend hours fixing what probably is a display driver issue that's pissing me off 😠2
At what point can I claim to not be a script kiddie anymore?
Like, I've built compilers, and interpreters for an excel-like syntax, I refactored a pdf-parsing library from the ground up. I managed databases and wrote protocols for communicating with hardware.
But most of my experience is with python / nodejs / golang. It is only recently that I started playing with C and rust for actual efficient system code.8
After a long year of going back to school for a masters. And working my ass off in networking events and internining. I can finally call myself a data scientist by job :D
Opinion: Julia will not catch on, because the two language problem is not a big issue for most people in the industry, and most python data scientist will refuse to migrate.
We had a tutorial on how to use spark/Hadoop.. part of the tutorial was the installation instructions for Ubuntu vms.
The Prof insisted we used an older version of Hadoop (v2.1.5), so naturally this required pulling older repos and older versions of java.
Naturally, some of the people in the class got some namespacing issues and garbage left from uninstalled packages.
Now, the tutorial was geared towards business/math people, not com sci. So most of the people didn't understand why apt didn't let them run certain commands (even though it very clearly just asked for them to run autoremove or autoclean, like in the "error message"). When the Prof and their "experienced TA" saw these messages, their recommendation was "make a new fresh vm".
The fuck? I heard that, run over and was like no. Just run the suggested command, it's literally a simple issue. And the guy didn't believe me. I had to sit him down, show him how I literally typed what the console was asking for, and everything just worked... The guy's response was "well that's Linux for you, its really complicated and can never trust anything, this time it worked, but next time it might not". Dude... Do you even know what you are saying? Like you are a supposed expert, least have some understanding of the package manager you are using. Maybe things will then be less "schrodinger cat".
God damn I can't wait to be out of this stupid fucking school. Never going back to academia.1
About 3 years ago, my girlfriend had this laptop that she got from her University. She had to give the laptop back to get reset, but didn't want to lose all of her data on it, and a backup would be around 750GB.
So I suggested that I would backup the laptop (was thinking to just dd an image and go from there). So I plugged in my mobile USB and external hard drive, and started the imaging process. Given the amount of data and setup, the process should have taken about 5hours. So we left it there for 5h.
Please be mindful that at this stage in my life I knew very little about boot processes, oses, and hardware.
5h after. The laptop screen is black and it ain't responsive. Not sure what happened, the dd process was completed, but the laptop refused to boot into windows. Tried a number of boot tools, and spent a crazy night hacking at the machine. But the university had some of sort of fail safe to not allow anyone to boot into windows if someone opened bios without entering a password. Whatever this was, I spent over 12h trying to either open mount the windows partition with a Ubuntu usb or mount the corrupt dd image on my laptop.
Long story short, after throwing at it a number of fixes. I was able to mount the image, copy out all of her personal data, and reinstall a new version of Windows on her laptop. The university didnt understand why the laptop was already reset. She still mentions this to me anytime I want to take a "custom approach" to software lol3
I used to think Electron apps were gonna do great and make it more accessible for companies to produce high quality programs with ease.
Oh boy I was wrong. All it did is enable big companies with the ability to refactor all of their software to run 5 times slower, consume 10 times more memory and kill your battery 20 times faster.
I fucking hate all of this prototype fast optimize later bullshit. Can I get some value for my dollar? How come technology is just being degraded for the same of "ease of programming".
You save programming time but sacrifice end user time, cus our time just doesn't fucking matter.11
Say what you want about npm and node_modules, it is much better than other package management systems like pip.
Least I don't need to create an entirely new installation of nodejs every time I want to build something new that might depend on some packages that depends on an 0.0.1 version lower of another package that is used by a different project I currently have to also maintain.
P.s. I do love python overall and it's ecosystem, the package management and version control are sheer garbage.2
Finally after waiting on the dashlane team to make a linux version of their application, I got tired and made it into a desktop application in a semi-hacky using the Jade-Application-Kit from the manjaro team <3
I feel like I should photopea next, would make a kind of "photoshop" for linux. :D9
I am currently running a heavily modded version of Ubuntu 18.04. I remove gnome applications, installed xfce with sddm for my login manager, plus removed a bunch of their pre-installed applications. I mostly use AppImages and snaps for installations with occasionally using apt for packages I am too lazy to build or are not in snap form.
I have been contemplating switching to Arch/Antegros/Manjaro. Mostly because I am crazy and heard that I could get a performance boost and I like being more in control of my own software.
My question is this, does it make sense for me to switch distros? Also, I'd like to have a close to the metal Arch install, but last time I did that I got annoyed with configuring too much from the bare bone, took me like close to an hour of setup, it was not hard, just really tedious.... Is Antegros/Manjaro have options to be really close to the bare-metal? Is there maybe a really good install script that I can just tweak some basic settings for?5
Thank you Syncex for one of the best powershell scripts ever. This literally sped up my laptop and surface :35
Just sitting here in class, when all the sudden my profs code shows up in the schools hall for no apparent reason....2
Yes. Please. Stop putting hidden files in my home directory. It's not the place for it.
