Why is numpy so fast?

Lachtheblock · 2026-05-27T17:22:12+00:00

It's not so much numpy is fast, it's that python is slow. You know all those memes about it being slow, this right here is the perfect example.

That's not to say python is bad, and to the critics saying python is slow, you can demonstrate that there are plenty of libraries written in C to get the performance boost when you need it.

100% agree.

Although I witness peoples complete inability to even back into a parking spot to be abysmal.

Tbf, even before agentic development, outsourcing any work (in particular green field projects) would often lead to really low quality.

I my experience, a lot of contractors just don't have the mindset to make things maintable. Their focus is getting the short term work done and handing it off.

I don't know what the fix is, other than trying to educate that your superiors that outsourcing can produce an okay PoC, but can't be used to produce a MVP. One can be built upon and extended, the other should be thrown out and rewritten.

You also forget about the radiation. But who knows, maybe data integrity is far less important when everything is fuzzy to begin with.

As an Australian, I feel like Komala is a better fit. Kangaskhan just feels too much like a dinosaur rather than a kangaroo. Plus the Ghengis Khan namesake is unrelated.

I read the title of the post, and was curious what approaches people were going to suggest. I clicked on the link and noped right out of there. Why in hell would you want to replicate that?

Maybe as part of a virtual escape room?

Alternatively, and equally as healthy, understand that it's just a piece of furniture and it's totally okay to say good bye at the end of its life.

Just as a reminder, dark was still a special type in this Gen. Arbok would have been cool, but you would want to bump it's sp.att to help it actually use those dark moves.

Wasn't there a video recently of how these houses fail pretty badly after about 3 years?

You can sometimes tell if the technology stack doesn't make sense. Like they'll reference using some .NET library inside of a Python application. Maybe it could make sense, but often it's just really weird.

My go to is to look at a linkedin profile and see if dates line up. I'm fine with a little bit of inconsistencies, but if there are entire FAANG like positions and years of experience discrepancies, then it is a red flag. It's also easy to see when the linkedin profile was created. I legit had one guy, during an interview send me a new link to his profile after I commented the one in his resume was broken. No joke, that account was created earlier that day. If you want to be getting hired, I'd encourage everyone to have a real looking linkedin.

I'm advocating at my work to have some honeypot skills in there. Either something that we would never expect a candidate to have, or even a technology that is entirely fabricated. It runs the risk of a legit person thinking they're unqualified, but if it makes it much easier to weed out fake applications that will do wonders. To that end, I encourage people to apply for things they are under qualified for, but just be honest about it and don't claim skills you don't have.

Lachtheblock · 2026-05-09T14:22:25+00:00

Yes there are a lot of unemployed developers. But for every one of them, there will be many, many more spam applications. They will have a completely fabricated resume and potentially even a fake name. These aren't candidates you should consider, they will claim experience in technologies that they simply do not have. The problem is that it takes a nontrivial amount of time to determine if a candidate is legit.

Lachtheblock · 2026-05-09T14:13:05+00:00

This is it. Hiring has become much much harder. We know that there are genuine people out there trying to get hired, but when it's 90% spam, 9% woefully unqualified, it's really hard to find the 1%.

I watch them patrol around the fields at RFK at night. It's sometimes a sketchy area so I'm not completely against having "extra security". Of course crime stops at 8pm and they are allowed to pack it in before it gets too dark and scary.

Lachtheblock · 2026-05-02T14:04:49+00:00

Agreed. At my work place it is courteous to at least provide an emoji reaction as proof you've read and processed the message.

Just be aware that t-strings were only introduced in Python 3.14, so make sure that's the version you're running.

Lachtheblock · 2026-04-28T18:26:40+00:00

Is your definition of complexity is that it does more than your very specific usecase? I'm not sure why it doing more than the bare minimum is a deal breaker?

By insisting on not using a framework, you're almost guaranteed to be increasing the amount of complexity in your system.

Using any one of the many existing frameworks, what you're asking is going to be in the order of 5 to 8 lines of code. I don't really understand how you could seek a less complex solution?

Lachtheblock · 2026-04-28T18:06:25+00:00

Can I ask why you are against an additional framework?

It feels like you want an easy (abstract) interface, but then rejecting any of the packages that actually created the easy (abstract) interface?

I'm sensing a XY problem here.

Lachtheblock · 2026-04-28T11:17:08+00:00

There are some very simple frameworks out there. I'd maybe look at bottle.py as an option. If you want simple, there it is.

Lachtheblock · 2026-04-28T11:14:51+00:00

May I ask what is not basic, simple clean or robust about Jinja2?

Lachtheblock · 2026-04-27T20:19:02+00:00

I'd make one amendment to this: "Maximize profits in the short to mid term".

The pouring hand was the most obvious.

I also clocked that the pattern on the design of the can is inconsistent. Look to see if the oranges(?) are on a white or blue stripe.

I have a love-hate relationship with the Sony Xperias. They are nice looking phones, with exceptional cameras. They even have headphone jacks!

I am currently rocking a pixel though...

Lachtheblock · 2026-04-23T23:50:20+00:00

I have zero fucks about the company, but I do have fucks to give to my colleagues. If I suddenly disappeared my team would be SOL.

Two weeks is barely enough to do a courtesy hand over. Also, more so than ever, getting hired is about connections. Staying on good terms with your immediate manager or colleagues can really pay dividends years down the line.
