Oh absolutely, for some tasks Python is amazing. I use Jupyter notebooks a lot, for example, and the flexibility is an incredible feature. It just worries me when I sometimes see those same Jupyter notebooks running in production, crunching

It doesn’t take 20k syscalls to print a plot, the 20k syscalls is for the import call. I would hope that drawing plots takes a lot less. To engage with your point: loading a dynamic library in a regular language takes significantly less tha

Carl Sagan’s novel Contact is ultimately about a surprising fictional mathematical result, although this is only revealed IIRC toward the end. The movie adaptation with Jody Foster changes the plot and leaves out much that the 90s movie stu

Sir, this is Hacker News. Replying with snarky arithmetic is pretty much the what passes for a bon mot around here. If you don't enjoy that, you will probably (>65% chance) find HN a stressful forum. OTOH, if you assume we're n

I'm not sure why you feel the need to double-quote that. At any rate, the book seems to cover UK law, and in fact is published at Oxford?

Hey now, it's possible to have written hundreds of thousands of lines of Python and worked on the internals (back in Python2 days) and still think it's terrible. (I don't, really, but that's because I don't try to u

Sure, but if it's a python application, you have two options: 1) Tweak the code without understanding* of how it'll affect performance, because every single line of code hides behind it such complexity that any improvement you fin

I don't mean optimization is pointless, I mean trying to optimize Python code for CPU performance is pointless. If you're going to spend the time to do that, just rewrite the critical section in a reasonable language, then wrap it

A little late to reply, but you're of course right, there's no direct way to compare the performance. Python serves (among others) a niche, where it's basically the glue between highly optimized C libraries like numpy. If you

While it points at interesting questions about Python's internals, I hope people writing Python realize that optimizing it is pointless, except for cases where you change the complexity class of an algorithm. The performance of pure py

I was surprised how bad these machines were in the UK and the US. It’s possible to implement the idea better. A big source of friction seems to be the (IMO) unreasonable focus on theft prevention, and the second is that stuff in the store i

The EU market is rough right now, as you say. The down-level to senior usually happens on the system design and behavioral interviews. Especially in Europe, I find people often downplay their contributions in these interviews, while the Ame

Yes, people at staff+ level are routinely hired. But these are typically very senior positions and you are expected to be in some way transformative. Staff engineers are roughly equivalent seniority to a manager of 6-12 people and should br

Managers are basically never consulted on layoffs. At a high enough level in the organization, you might find out a week or two before everyone else and mark some people as critical, but that's about it. Basically every company I'

The people they are hiring are probably cheaper than the people being laid off. The costs of the layoff are massive in morale, lost know how, missed opportunities, etc. But to the finance people, that's just as well because it's n

According to their wikipedia page, at least, Spirit AeroSystems are a Boeing spinoff in any case, and something like 85% of their sales is only to Boeing. It seems like corporate budget maneuver, and a distinction I, a member of the flying

Container vulnerabilities are rarely related to memory bugs. Most vulnerabilities in container deployments are due to logical bugs, misconfiguration, etc. C-level memory stuff is absolutely NOT the reason why virtualization is safer, and no

Sure, if the program crashes, all bets are off. That’s also true of any other similar exception mechanism. The fact that the program crashes on unhandled panic, rather than letting you install a default global handler, is a design choice th
