New comment by skarap in "Throw away code"

Python isn't weakly-typed.

> Over the years, I’ve used Perl a lot (that one doesn’t care if it’s int or string… no, correction, in Perl everything is a string, ints just don’t exist. Well, kind of). It’s probably the language designed for throw away coding. I’ve done some Python too (that’s like Perl, but with proper objects in it, and everything is a dictionary there).

The author has almost no real programming experience with Python. Perl experience seems to overlap with sysadmin-related work at least partially, where it's usually used as better Bash. All their repositories in GitHub are Rust. So almost all of "real" programming they did used Rust.

Why would anyone who know Rust way better than any other language prefer to do their prototypes using anything else?

Depends on whom you ask. There are people who use it exactly because when "things break at random" they absolutely can understand the reasons and actually fix it in contrast to some other OSes (or Linux from more recent years).

New comment by skarap in "Self-driving Uber car kills Arizona woman crossing street"

skarap — Mon, 19 Mar 2018 18:05:15 +0000

To repeat my comment from a previous discussion which brought a lot of downvotes: what happens when (not if) a self-driving car runs-over and kills someone (e.g. because of a software bug)? Do such cases cause criminal penalties? Who is penalized? Or will all cases of autonomous car accidents with deaths become civil cases? If so - do human drivers get the same new rules or if they kill someone by accident (because they got distracted) they still go to jail? Is that fair?

In this particular case I assume the operator will be thrown under the bus, which is also unfair.

Exactly. Asynchronous programming + promises + some unhandled failure case somewhere and you end up with timeouts instead of error responses.

So what happens when one of these cars runs over someone?

New comment by skarap in "Oh shit, git: Getting myself out of bad situations"

skarap — Mon, 18 Dec 2017 17:04:11 +0000

One can read any amount of similar articles, but if they don't understand the data model behind all this, git will remain a complex and fragile beast for them. The feature-set is huge to be able to just remember all possible commands for all possible scenarios. If you don't know what index is or what a branch is, this all will look like a bunch of nonsense. On the other hand - your ruby code won't seem too logical either if you don't know the language.

So if git is the tool you use to get your job done - don't hesitate to spend a day or 2 on reading how it works and how you're supposed to use it.

> Deciding to hire both, and then assigning them to the same team is clearly the wrong solution

Couldn't Microsoft also get into trouble by hiring just one of them (the other one could have a good case for being treated unfairly)? And what if they don't have 2 separate teams which need new members? Should they create a new team just to make sure they don't heart anybody's feelings?

You're throwing away a datapoint - "the police decided not to press charges or Bob was found not-guilty in court".

Not a lawyer, but isn't is taken for granted that lawyers (along with everybody else) are lying in courts and that it's the jurors and judge's job to find out who is lying?

New comment by skarap in "SSH vs. OpenVPN for Tunneling"

skarap — Sun, 26 Nov 2017 10:53:57 +0000

`ip link set qlen 1000 dev tun0` (so it matches the eth0 queue, instead of being an order of magnitude smaller) on both ends of the tunnel, and you get 90% of direct connection speed from openvpn:

That's the only reason for most of their clients. "We get periodic security scans from a respected vendor, yes sir!".

I can't rule out that the scanners might work, but if the vendor isn't naive, they'd be optimizing for their real target audience.

One congestion-control parameter which don't get it's fair share of articles is initcwnd. And for HTTP traffic over high bandwidth+latency links it has much larger impact than the choice of the cc algorithm.

There is a reason. It makes people switch from own email servers to gmail.
