yeah, i edited my comment while you were replying to note that /g is a valid flag for m/// as well. it is a valid perl matching operation precisely as-is but it can’t match anything due to the spaces it has before the ^ and after the $.

from the /g at the end i agree it looks like it could be a malformed attempt at an awk/perl/etc substitution operation, and your rewrite of it as an s/// does work, but the parts between the ^ and $ would also be a valid regexp in Perl-compatible regexp and some other dialects if not for the spaces at the start and end. And, the /g is also a flag (“Match globally, i.e., find all occurrences.”) for the m/// matching operator in Perl.

The \1 and \2 are backreferences to the capture groups, which can be used not only in the replacement part but also in the pattern itself.

You can see this working by running this command:

echo '123 - 45 - 67890 45 123'|perl -ne 'print if m/^(\d{3}) - (\d{2}) - (\d{5}) \2 \1$/g'

…which will echo the string because it matches the pattern. (if you edit the input string to change, for instance, the last digit, it will no longer match and will output nothing.)

There is no input that can match the pattern as it is in the comic with the space before the ^ and after the $ however.

Interestingly backreferences are also supported by POSIX Basic Regular Expressions (BRE), but are not supported by POSIX Extended Regular Expressions (ERE). (Also the former requires you to escape parenthesis and curly braces for them to become meta characters, while the latter requires you to escape them if they’re literals as Perl etc do. And neither of the POSIX flavors supports \d as a shortcut for [0-9].)

which music genres do you like?

Did you not read the post? OP clearly says:

I ran the numbers and I like every single music genre pretty much equally

😂

tuta is (like proton) snake oil. (here and here are two of my old comments about why…)

Mailbox.org lets you keep your own private key.

Every email provider lets you keep your own private key if you do encryption using the interoperable OpenPGP standard using software running on your own computer. Many email providers will recommend that you do exactly that, and will helpfully instruct you about how to do so (eg, the more reputable options in this thread such as migadu.com, mailbox.org, posteo.de, and even fastmail.com all have instructions for how to use some implementation of pgp to encrypt your email).

Meanwhile any company selling non-standard “email encryption” (eg, proton and tuta) which is not compatible with pgp (or, in the corporate world, s/mime, which is also a standard…) is firmly in the snake oil business and should be distrusted and boycotted regardless of which shitty youtubers they’re sponsoring this week.

that may be true but you should consider that HR departments are notorious for failing to document complaints from members of socially-disadvantaged groups

He even managed to pull off cardassian with sideburns

Combs did not ever play a Cardassian.

Are you referring to his appearance on Voyager, where he played the vaguely-cardassian-resembling Penk?

The one who signed it did (though i don’t think it was for that per se)

It might be outdated in other ways but it isn’t wrong about U+2753 being BLACK QUESTION MARK ORNAMENT: the character is still called that in Unicode, and that remains an accurate description of its text presentation despite its emoji name being “red question mark” and its emoji presentation being in red.

emoji presentation: ❓

text presentation: ❓︎

you can force it to its text presentation by suffixing it with the text presentation selector U+FE0E VARIATION SELECTOR-15 (VS15); to put the text presentation above i copy+pasted the output of python -c 'print("\u2753\uFE0E")'

Emojipedia confusingly says:

Red Question Mark was approved as part of Unicode 6.0 in 2010 under the name “Black Question Mark Ornament” and added to Emoji 1.0 in 2015.

In fact Emoji 1.0, 2.0, and 3.0 all called U+2753 “BLACK QUESTION MARK ORNAMENT” as Unicode did. In Emoji 4.0 through 13.0 (they jumped from 5.0 to 11.0 btw, to sync the version with Unicode) it was renamed to simply “question mark”, and it wasn’t until Emoji 13.1 in 2020 that it was finally renamed to “red question mark”.

In the latest release of Unicode, 17.0.0, it remains “BLACK QUESTION MARK ORNAMENT”.

I don’t follow how a useful thing becomes “useless” or “no point” just because millions of people are unjustly denied access to it.

Fwiw Let’s Encrypt was just the first but isn’t actually the only free ACME provider anymore; acme.sh has a list of other providers in its readme and there is another list here. Actalis is Italian apparently; unfortunately I think the rest might be ultimately US-based (ZeroSSL says it’s Austrian but it’s owned by a US company).

It would be nice if some more independent country (eg, China) who already has one or more CAs trusted by all major browsers would step up and start offering free certs to the world.

It’s worth noting that HTTPS is needed not only for its confidentiality and authenticity properties, but also is required by browsers for pages to be allowed to use modern features like WebRTC (needed to have a voice or video call from a web page).

It’s much easier said than done. Anyone can start a new Certificate Authority but for it to be useful internationally it (its public key) needs to be built-in to (trusted by) all of the popular web browsers, the largest of which are all controlled by US companies.

effectively making it useless

do you know what Let’s Encrypt is? it is very far from useless; the system it is a part of is very flawed but it’s how the web works currently and US sanctions restricting access to it is absurd.

Companies now block older browser versions

Now? This has been happening since the dawn of the web. At least the screenshot you pasted represents all of the big three rendering engines - it used to be common to see “Internet Explorer version XYZ required”, sometimes with javascript to prevent you from using the site with any other browser (even if in some cases it would actually work fine if you simply spoofed your user agent string).

I have used kinda retro devices to surf the web at times

Most websites became HTTPS-only sometime after the snowden disclosures in 2013.

Over time old versions of TLS have been deprecated and eventually support for them is dropped from browsers and web servers alike. So, a browser from even 15 years ago literally cannot connect to most webservers today.

Planned obsolescence is terrible but it’s a minor factor here: it’s actually dangerous to use even (especially?) a slightly-out-of-date web browser because every new release fixes vulnerabilities which can be exploited to run malicious code on your computer. The planned obsolescence which prevents people from being able to have an up-to-date browser comes mostly from proprietary operating system vendors; to have up-to-date software while continuing to use somewhat older computers you need to use free/libre software.

don’t threaten me with a good time
