I thought this was going to be about Android (which makes heavy use of that term), and I was expecting completely different complaints: - The toast disappears quickly, so you might not have time to read it / take a screenshot - It&#x27

Wolfram Alpha's math input is broken(wolframalpha.com)

There is a serious bug in Wolfram Alpha's "math input" mode. When you enter e²ⁿ, it is interpreted as e²n (full details at the end). This was reported to them a month ago and still hasn't been fixed, so I figured it was

Docker & co. also let you create a clean build environment (to a lesser extent), and I find them less intrusive than Nix / Guix.

Great sleuthing, the missing piece of the puzzle is that the file contents are inside a <code> element while the line numbers are not, and <code> elements have a default font so they don't inherit the font from their parent

In fact the article mentions a tool for this (sslh), but rejects it because it hides the source IP from the HTTP backend (and other reasons).

In the case of SSH, there is a single connection (in fact SSH implements its own multiplexing), so I don't see the advantage of HTTP/2.

I agree. Stack Exchange's Code Golf has public source, but the best there is 644 bytes: https://codegolf.stackexchange.com/a/4198

Yes, that's likely to work on many firewalls, but: - it means you can't also serve HTTP on those ports (so you'd need a dedicated IP address for SSH), and - as @charcircuit wrote, it won't resist deep packet inspection.

This article is not about graphics drivers. The project in question is "advanced parking and driving assistance technology".

A clever person got that account banned. When you try logging in with that email and a random password, it will fail, and Windows will allow you create a local account. (ref: https://news.ycombinator.com/item?id=37179504 ,

It is perfectly reasonable and consistent for one thread to set an environment variable while other threads are reading different environment variables.

Sure, some applications might require custom higher-level synchronisation, but it's still important for getenv/setenv to be thread-safe (i.e. not crash): - The race might be irrelevant (e.g. simultaneous calls that access differen

In Chrome you can inspect your closure (as you clarified in https://news.ycombinator.com/item?id=38226743#38231705 ) using the "Watch" pane, and then look at its "[[Scopes]]" pseudo-property. I don't

Very cool. Some small criticism/feedback: - Pluto is shown as if it is spinning around itself, but in reality Charon (its largest moon) is so heavy (12.2% of Pluto) that their barycentre ( https://en.wikipedia.org/wiki&#

It's not a big deal because there is no need to retry 20 times. The probability of getting a deleted article several times in a row is very low, so you could limit to e.g. 5 tries, and if all are deleted fall back to the next non-delet

For the curious: They make getenv() thread-safe by intentionally leaking the old environment, which they argue is acceptable because the memory leak is bounded to 3x the space actually needed. The getenv/setenv/putenv/envir

Good point about `putenv()`; however there is also `setenv()`, which does make a copy, so you are wrong about `getenv()` in general. POSIX explicitly states "The string [returned by getenv] may be overwritten by a subsequent call to

You have a minor bug -- when len(lst) is a multiple of batch_size, this will have an extra iteration at the end with an empty batch. The fixed version is `range((len(lst) + batch_size - 1) // batch_size)`, which emulates `ceil(len

The attackers didn't even use a trojan project/source. They just sent a malicious .exe (wrapped in an .iso file) and asked the victim to run it and write a C++ program that produces the same output.

I'm also curious about this; I don't know how secure the traditional native clients are (FreeRDP, Vinagre, Remmina, etc.). On the other hand, there are browser-based clients such as Apache Guacamole and noVNC, which are protected
