lj·rk<p>Maybe I'm just too tired to find a way for `podlet` to write it's output to multiple files if there are multiple files to generate.

What's useful about Perl is that it fits the Unix tools approach well. You can write quick one-liners and put them in a pipeline. You then gradually enhance functionality until you arrive at a standalone script. Like Shell. Like AWK. Ruby is kind of like that as well. Python is not.

This doesn't mean the opposite works equally well. The bare minimum to turn a language's REPL into an interactive Shell is I/O redirection and pipelines without much extra syntax.

Hey beloved #noGooMe users,

A quick reminder that you *must* have the proxy image option unchecked when using this #SearxNG 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 #awk 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 Bologov

I still can't believe that most programming systems we use today are preoccupied with numbers. AFAIK, half of (R5RS?) #Scheme standard is numbers and operations on them. Same for #C, #CommonLisp, #Java—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; #ed1 and #awk are considered mere #regex 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.
