Space Hobo<a href="https://graphics.social/@metin" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@metin</a> I see you and raise you <a href="https://teh.entar.net/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> on a terminal: <a href="https://github.com/patsie75/awk-demo" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/patsie75/awk-demo</a>

SlatianHey xdg-shell-linux fedi corner :drgn: I need some eyes on this code here: <a href="https://gitlab.freedesktop.org/xdg/xdg-utils/-/merge_requests/147" rel="nofollow noopener noreferrer" target="_blank">https://gitlab.freedesktop.org/xdg/xdg-utils/-/merge_requests/147</a><a class="hashtag" href="https://pleroma.envs.net/tag/linux" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a class="hashtag" href="https://pleroma.envs.net/tag/awk" rel="nofollow noopener noreferrer" target="_blank">#awk</a> <a class="hashtag" href="https://pleroma.envs.net/tag/freedesktop" rel="nofollow noopener noreferrer" target="_blank">#freedesktop</a> <a class="hashtag" href="https://pleroma.envs.net/tag/xdg" rel="nofollow noopener noreferrer" target="_blank">#xdg</a> <a class="hashtag" href="https://pleroma.envs.net/tag/xdgutils" rel="nofollow noopener noreferrer" target="_blank">#xdgutils</a> <a class="hashtag" href="https://pleroma.envs.net/tag/shell" rel="nofollow noopener noreferrer" target="_blank">#shell</a>

Space HoboHey <a href="https://teh.entar.net/tags/entr" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#entr</a> fans: are there any examples of a `$ENTR_STATUS_SCRIPT` script out in the wild, or any explanation for what this feature was meant to do? It seems like it could be useful, and I'm a huge fan of <a href="https://teh.entar.net/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a>, but I can't find anyone explaining what they do with it.

SebasTEAanI created some code to reformat the output of ip --brief to look a bit cleaner (IMO).You can find the code in <a href="https://github.com/SebastianMeisel/mybashrc" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/SebastianMeisel/mybashrc</a> .<a href="https://linuxrocks.online/tags/ip" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ip</a> <a href="https://linuxrocks.online/tags/ipv6" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ipv6</a> <a href="https://linuxrocks.online/tags/bash" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bash</a> <a href="https://linuxrocks.online/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> <a href="https://linuxrocks.online/tags/cli" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cli</a>

Tim ChaseTIL that modifying NF in <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> has an instant effect, so if you do$ echo a b c | awk '{while (NF){print $(NF--)}}'the post-decrementing removes the entry before the variable gets accessed, resulting in it printing blanks, so instead you have to access the variable before doing the post-decrement:$ echo a b c | awk '{while (NF){print $NF; NF--}}'to print each item in reverse.Which seems weird given what I understand about how post-decrement is *supposed* to work.(HT: <a href="https://oldbytes.space/@drscriptt" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@drscriptt</a> whose <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> sent me down this rabbit-hole of learning)

DrScriptt<a href="https://mastodon.bsd.cafe/@gumnos" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@gumnos</a> That didn't quite work, but I did get it to work.Here's what I have:awk -F. '{for (C=NF;C; C--){printf "%s.", $C}; printf "oid."}'NF-1 was missing a component.I also added curly braces around the 1st printf to make it more obvious what the for loop applied to.I wasn't aware that the for loop only applied to the very next instruction. <a href="https://oldbytes.space/tags/TIL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TIL</a> <a href="https://oldbytes.space/tags/AWK" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AWK</a>

DrScripttWell I did a thing.I created a <a href="https://oldbytes.space/tags/DNS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DNS</a> zone; .oid, on my DNS server <a href="https://oldbytes.space/tags/OIDs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OIDs</a>.I can now easily look up OID values with dig (et al.):% dig +short txt 2.3.7.5.5.1.6.3.1.oid.To look up OIS 1.3.6.1.5.5.7.3.2.I also wrote a one* line shell script to make doing the lookups easier:\dig +short txt $(echo ${1} | awk -F. '{for (C=NF; C>1; C--){printf "%s.", $C}; printf "%s.oid.", $1}') | sed 's/"//g' <a href="https://oldbytes.space/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a>So I can now run:% oidlookup 1.3.6.1.5.5.7.3.2and get the following output:{iso(1) identified-organization(3) dod(6) internet(1) security(5) mechanisms(5) pkix(7) kp(3) id-kp-clientAuth(2)}

Willem Van den Ende - WritingEnjoyed <a href="https://mastodon.social/@kevlin" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@kevlin</a> on 'past and future of programming languages' yesterday. I am an outlier, I programmed in three languages outside the top 20 this week - <a href="https://mastodon.social/tags/elixir" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#elixir</a>, <a href="https://mastodon.social/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> (emacs) and <a href="https://mastodon.social/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> (it comes bundled with most linux, and I have it on mac as well). Strangely enough, a local <a href="https://mastodon.social/tags/llm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#llm</a> makes the latter two more approachable. qwen3:30 is quite good at generating awk, and good enough to get almost-working <a href="https://mastodon.social/tags/emacs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#emacs</a> lisp.

LeJaxCurrently testing <a href="https://mastodon.bsd.cafe/@stefano" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@stefano</a> 's <a href="https://mastodon.bsd.cafe/tags/BSSG" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSSG</a> Seems that I could, with minor mis features, switch from <a href="https://mastodon.bsd.cafe/tags/Hugo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hugo</a> to <a href="https://mastodon.bsd.cafe/tags/BSSG" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSSG</a> May be I will need some <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a>, <a href="https://mastodon.bsd.cafe/tags/sed" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sed</a> and <a href="https://mastodon.bsd.cafe/tags/sh" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sh</a>Need to take notes for a blog post.

NoGoo.meHey beloved <a href="https://gts.nogoo.me/tags/nogoome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#noGooMe</a> users, A quick reminder that you *must* have the proxy image option unchecked when using this <a href="https://gts.nogoo.me/tags/searxng" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SearxNG</a> instance. It can be disabled, if you previously had it enabled, browsing to /preferences, then selecting the "privacy" tab and uncheck the "image proxy" switch. It is disabled by default so any first connection to this instance has the proper setting set up. If you do have it enabled, you’ll quickly be blocked at the firewall level by our <a href="https://gts.nogoo.me/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> AI agent 🤖 My reason for disabling this feature is that it generates loads of requests from the instance IP to the external engines. And this makes those block us really fast. This means that the engines will have *your IP* logged when you search for images, only. Classical text search are still masqueraded with our instance IP.

Artyom BologovI still can't believe that most programming systems we use today are preoccupied with numbers. AFAIK, half of (R5RS?) <a href="https://merveilles.town/tags/Scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scheme</a> standard is numbers and operations on them. Same for <a href="https://merveilles.town/tags/C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C</a>, <a href="https://merveilles.town/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a>, <a href="https://merveilles.town/tags/Java" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Java</a>—ten different types of numbers and huge libraries for them.Humans think in images and words. Structured text-oriented languages feel like a much better fit for everyone not corrupted by C. Yet we have little to no popular attempts in that space. Structured Regular Expressions didn't catch up; <a href="https://merveilles.town/tags/ed1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ed1</a> and <a href="https://merveilles.town/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> are considered mere <a href="https://merveilles.town/tags/regex" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#regex</a> automation tools. Modal and the term rewriting systems have their Merveilles Town, but not much beyond. sh/#bash and the like are quite successful, but aren't considered real programming languages either.Why.<a href="https://merveilles.town/tags/theRant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theRant</a>

Jonathan LamotheI am in urgent job search mode, so I'm gonna throw this out here and see if anything comes of it.I am a <a href="https://social.jlamothe.net/search?tag=Canadian" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Canadian</a>, fluent in both <a href="https://social.jlamothe.net/search?tag=English" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#English</a> and <a href="https://social.jlamothe.net/search?tag=French" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#French</a>. I have experience with several programming languages.

I just need something stable. I have done everything from software development, to customer support, to factory work, though my current circumstances make in-person work more difficult than remote work. I have been regarded as a hard worker in every job I have ever held.<a href="https://social.jlamothe.net/search?tag=GetFediHired" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GetFediHired</a>

Joel Carnat ♑ 🤪I found a bug in my <a href="https://piou.foolbazar.eu/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> AI bot that ended up blacklisting to many IPs. Because of a variable I thought would be initialized but turned out to be containing a previous value. I fear that this makes me a developer. A poor one, but one still.

Donald Hobern<a href="https://tau-ceti.space/@ics" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@ics</a> For me, it was during a lull in my workload at the <a href="https://scicomm.xyz/tags/IBM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IBM</a> Hursley lab in the UK when I worked my way through the O'Reilly <a href="https://scicomm.xyz/tags/sed" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sed</a> & <a href="https://scicomm.xyz/tags/awk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#awk</a> book (the one with the two lorises on the cover).I'm guessing it was 1995 because my annual birdwatching summary at the start of the next year switched from a fixed column text document to formatting in <a href="https://scicomm.xyz/tags/Postscript" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Postscript</a>. My first big awk project was to process the underlying data to generate a PS document (something I also learned in the same downtime period).
