I never expected embedded Linux to be this performant boot wise. On a Cyclone V HPS (800Mhz, Coretex A7) the entire system boots in 3s. Thats from power on to a shell in userspace. And it uses like 40MB of SD-Card Space. The entire speed gets throuwn out the window as soon as you use systemd. Then it takes like five times as long. I kinda want to explore this further in the future by addin LCD support with a desktop environment and get some numbers for that. Currently very happy with the results.

For learning purposes, I made a minimal TensorFlow.js re-implementation of Karpathy’s minGPT (Generative Pre-trained Transformer). One nice side effect of having the 300-lines-of-code model in a .ts file is that you can train it on a GPU in the browser.

The Python and Pytorch version still seems much more elegant and easy to read though...

Just had the realization that the reason why the internet is so toxic isn't really because of anonymity

It's because if you're a massive asshole to someone, that person can't punch you in the face

I mean this for real, and it's kinda counter intuitive, but the underlying threat of violence is what keeps society civil and polite

what the fuck did i just read rn

don't hack hungry, guys

It wasnt a Phillips Head screw. It was Pozidriv!

Looks like I can finally post images

Manager: You want a promotion? To senior? Ha. Well, build this web app from scratch, quickly, while still doing all your other duties, and maybe someone will notice and maybe they’ll think about giving you a promotion! It’ll give you great visibility within the company.

Your first project is adding SSO using this third party. It should take you a week.

Third party implementation details: extremely verbose, and assumes that you know how it works already and have most of it set up. 👌🏻

Alternative: missing half the details, and vastly different implementation from the above

Alternative: missing 80%; a patch for an unknown version of some other implementation, also vastly different.

FFS.
Okay, I roll my own auth, but need creds and a remote account added with the redirects and such, and ask security. “I’m building a new rails app and need to set up an SSO integration to allow employees to log in. I need <details> from <service>.” etc. easy request; what could go wrong?

Security: what’s a SSO integration do you need to log in maybe you don’t remember your email I can help you with that but what’s an integration what’s a client do you mean a merchant why do merchants need this

Security: oh are you talking about an integration I got confused because you said not SSO earlier let me do that for you I’ve never done it before hang on is this a web app

Security: okay I made the SSO app here you go let me share it hang on <sends …SSL certificate authority?>

Boss: so what’s taking so long? You should be about done now that you’ve had a day and a half to work on this.

Abajdgakshdg.

Fucking room temperature IQ “enterprise security admin.”
Fucking overworked.
Fucking overstressed.

I threw my work laptop across the room and stepped on it on my way out the door.
Fuck this shit.

here I fixed the cat command

Potential client once asked for a clone of Amazon, for $5000, in one month. I did not take the project.

I've made the json protocol. It's a protocol containing only json. No http or anything.

To parse an json object from a stream, you need a function that returns the length of the first object/array of all your received data. The result of that function is to get the right chunk of the json to deserialize.

For such function, json needs to be parsed, so I wrote that function in C to be used with my C server and Python client. I finally implemented a C function into python function that has a real benefit / use case. Else you had to validate but by bit by the python json parser and that's slow while streaming. Some messages are quite big.

Advantage of this protocol is that it's full duplex.

I'm very happy!

Update to my "I broke prod" rant:

- I managed to unfuck it on the same evening.
- Worked fine for one day
- Crashed today morning
- Can't fix it because I had surgery yesterday and am on sick leave currently
=> Probably gonna result in me VPNing into the comp network and RDPing into the prod instance to analyse the failure

Yep, ladies and gents, more open heart surgery on the menu!

"Strap On" backwards is "No Parts"

I did it.

I finally fucked prod.

And had to do open heart surgery on the service to get it unfucked.

Shit happens. Luckily its internal prod only...

dark chocolate is so good. I'm addicted and keep eating so much of it every day of late

is there foods you find extremely pleasurable to eat?

Regex and off by 1 capture group...

What you doin' with a time machine? I mostly just use my time machines to tell time.

omg it's been 3 months they've been nitpicking this fucking project by looking for one frame drift on a 4 hours video.

The fuck is it with the three or so "anti german" accounts?

how to be a shitty client:
- have a legacy database where column names are misspelled and everything is nullable
- hire external help which instead of helping break the ui (bonus points for breaking the api too)
- demand a very much custom auth logic but decide to use aws cognito for shits and giggles
- demand 1hr daily meetings
- demand biometric auth with 0 knowledge of how biometric auth works (the previous devs just had a face id prompt which does nothing and retrieved email and password saved on the device???)
- message me at 2am because you don't understand how timezones work + demand a build while you're at it
- call me a "heretical pagan" because i took a day off on a holiday you don't celebrate (???)

i could go on but i think this is enough

I'm so happy

In the future, everything will run in the browser, and you will be happy

rust is just ugly

Got scammed on devrant by sketchy cryptocoin recovery services? Like a total dumb ass you clicked a sketchy link? Did you suffer temporary retardation and believed a scammer?

You may be entitled to public humiliation! Contact our services (totally not sketchy AF) and get doxxed, reposted, and made to look like a complete fool! (Javascript devs excluded, they suffer enough just existing.)

I feel bad for my ex-colleague. He left the company for multiple reasons and is now employed for 2-3 months somewhere else as a freelancer.

That company just announced they'll outsource all their freelancers to India. Now he has to job search again :(

I think I'll never going to get a devRant stress ball, so i made this instead with my pretty low budget (0.5$).

Apparently inverse sigmoid is how logits are calculated.

Here I am reinventing the fucking wheel.

New developers(5-6 years experience) these days are so pathetic. They dont have any sense of code review. All they want is to put their opinion out without giving any thought.

I had a PR for review today which contains mock specification to match a regular expression and return the corresponding response

The regular expression I put was

104000(02|06|20|48)

Now, this guy comes and puts a comment that we could "simplify" as 104000\d{2}

I replied, the ending digits are not contiguous. The specific pair of digits have to match for these mocks.

Then this guy replied, then we could simplify as 104(0{4}(2|6)l0{3}(20|48)).

I said, I cannot understand how that is simplification. Why do we need such a complex regex to match something very straight forward.

And the guy replied, we should be writing proper regexes, otherwise we could just specify everything explicitly.

I was like WTF man. You try deciphering this next week without taking at least a minute to know which values are matched.

Anyhow, another senior person approved my PR, and I merged it.
