sudahtigabulan··on Registration without a phone number on Signal will use zero-knowledge proofs
This setting is "Always relay calls", and the only difference it makes is for already established calls. Messages and calls setup always go through Signal's servers.

> The P/B distinction will be difficult for many people as well.

P/V/F confusion is also a thing, in Indonesia.

V and F tend to be pronounced as P. And if you pronounce the letter "correctly", some Indonesians might not recognize the word. They've never heard it this way.

sudahtigabulan··on A Friendly Introduction to Racket
> Wtf kind of intro to a programming language doesn’t include syntax rules?

PP could have been more clear and say syntax-rules (note the dash), which means macros. Macros are usually considered an advanced topic.

sudahtigabulan··on Rhombus 1.1 is now available
There is a naming tradition in the Lisp world, which Racket devs apparently have chosen over searchability.

Qualities or activities that have negative connotations. Guile. Gauche. Larceny. Racket.

I think it started with theorem provers - Planner, Conniver. Then Scheme[r].

It has to do with the codes these keys (used to) emit in combination with Ctrl:

  Ctrl/H - Backspace

  Ctrl/K - Upline

sudahtigabulan··on Poland directs officials to ditch Signal in favor of 'secure' Polish alternative
I think Signal should stop doing their new feature announcements in the form of chat messages.

This weakens their claim "we don't contact users", because it makes it look like they do.

Dedicated UI, like bottom sheets, snackbars, etc., doesn't have this problem.

sudahtigabulan··on My .config Ship of Theseus
Given that most software hides dot files by default, where do you see them so often?

The only place I've encountered where they are visible by default and do get in the way is bash filename completion, and you can change this via the readline config file:

  # ~/.inputrc:
  set match-hidden-files off

> a 60 question test with 50 minutes of allotted time

Is this kind of test - many short questions - a standard thing for math in your country?

My university exams were pretty much all "2-question", in 90 minutes.

The first half was an essay where you have to reproduce a lesson from the curriculum, in your own words.

The second half was "the formulas" - you have to develop one or two formulas from first principles.

I once got an A- even though I got "the formulas" half very wrong. As the teacher explained later, I simply chose the coordinate system beginning at not the same place the textbook did. And this was supposed to be a bad teacher - he actually gave Ds to almost all of us (180 people). This was a makeup exam.

Try publishing on https://repo.or.cz (or another old-style web interface), and just leave an email for contact.

You will hear only crickets.

Adding the slightest friction, and making potential drama 1:1 only, demotivates most people.

You might miss out on an occasional good feedback, though.

sudahtigabulan··on Why are we still using Markdown?
> Maybe using an unnatural placement of )parentheses( could have worked as a non-conflicting indicator of italics.

Using different delimiter for opening and closing is a good idea on its own, too. I think it makes parsing simpler and unambiguous wrt nesting.

I've imagined something like this:

  `(monospace)
  _(underline)
  /(italics)
  ~(overstrike)
Probably looks a bit more distracting, though.

sudahtigabulan··on Stop Putting Secrets in .env Files
> They sit on disk as plaintext, readable by any process running as your user

The proposed solution:

> Instead of loading secrets from a file, you use a wrapper script that fetches secrets from a secure store and injects them as environment variables into your process

Now they sit "on disk" as plaintext, in /proc/self/environ, still readable by any process running as your user.

> I've since learned that anything heavily regulated like hospitals and banks will have security procedures catering to compliance, not actual security.

Sadly, yeah. And will do anything only if they believe they can actually be caught.

An EU-wide bank I used to be customer of until recently, supported login with Qualified Electronic Signatures, but only if your dongle supports... SHA-1. Mine didn't. It's been deprecated at least a decade ago.

A government-certified identity provider made software that supposedly allowed you to have multiple such electronic signatures plugged in, presenting them in a list, but if one of them happened to be a YubiKey... crash. YubiKey conforms to the same standard as the PIV modules they sold, but the developers made some assumptions beyond the standard. I just wanted their software not to crash while my YubiKey is plugged in. I reported it, and they replied that it's not their problem.

It's not a trap, I promise! Just fishing for ideas.

If it's too long, it gets truncated, though.

sudahtigabulan··on Awk Technical Notes (2023)
> What were you expecting? That your character ranges in ls would match mine?

I would expect the command to work in any directory. Try a few different directories on your computer and you'll see that it won't work in some of them.

sudahtigabulan··on Awk Technical Notes (2023)
Can these flags be used to extract the N-th column (say, the size) of every line from ls -l output?
sudahtigabulan··on Awk Technical Notes (2023)
> That’s typical usage of Awk, where you use it in place of cut because you can’t be bothered to remember the right flags for cut.

Even you remember the flags, cut(1) will not be able to handle ls -l. And any command that uses spaces for aligning the text into fixed-width columns.

Unlike awk(1), cut(1) only works with delimiters that are a single character. Meaning, a run of spaces will be treated like several empty fields. And, depending on factors you don't control, every line will have different number of fields in it, and the data you need to extract will be in a different field.

You can either switch to awk(1), because its default field separator treats runs of spaces as one, or squeeze them with tr(1) first:

  ls -l | tr -s' ' | cut -d' ' -f3
sudahtigabulan··on An overengineered solution to `sort | uniq -c` with 25x throughput (hist)
> once you develop a good enough utility library for it.

What happens when everybody comes to the job with their own utility library and start working on the same codebase?

Would you like it if you had to get up to speed with several utility libraries your coworkers developed for themselves?

A common set of tools, like the Unix commands, makes it easier for people to collaborate. They were put in an official standard for a reason.

sudahtigabulan··on An overengineered solution to `sort | uniq -c` with 25x throughput (hist)
The 2 minutes wasted to write it doesn't move the needle, but the time that their present and future teammates will waste on reading it might.

It costs me more effort to read and understand a screenful of unfamiliar code than the equivalent "sort -k 1.1" or "uniq" while skimming through a shell script. This adds up.

sudahtigabulan··on Google Pixel's most dangerous bug: failing to call 911
I think touch screen itself limits the possibilities to create UIs usable with minimum attention. You have to look at it to find the right area to press. All those buttons, knobs, sliders, etc., imitate the real thing, but only in 2D. Can't rely on feeling to find the right control, unlike with physical designs.

It's not the only culprit, of course. There's still room to at least design a layout that is predictable, and with buttons that are easily reachable.

Some UIs make me think the designer was an alien invader in a human body. It thinks nobody can tell, but when it designs a UI that can only be called "intuitive" if you have 7 fingers, the 2-nd and 5-th longer than the others, and the 3-rd one a tentacle... I got you, motherfucker!

sudahtigabulan··on SourceFS: A 2h+ Android build becomes a 15m task with a virtual filesystem
This reminds me of ClearCase and its MVFS.

Builds were audited by somehow intercepting things like open(2) and getenv(3) invoked by a compiler or similar tool, and each produced object had an associated record listing the full path to the tool that produced it, its accurate dependencies (exact versions), and environment variables that were actually used. Anything that could affect the reproducibility was captured.

If an object was about to be built with the exact same circumstances as those in an existing record, the old object was reused, or "winked-in", as they called it.

It also provided versioning at filesystem level, so one could write something like file.c@@/trunk/branch/subbranch/3 and use it with any program without having to run a VCS client. The version part of the "filename" was seen as regular subdirectories, so you could autocomplete it even with ancient shells (I used it on Solaris).
