twts are taking a very long time to post from yarn after the latest upgrade. Like a good 60 seconds.

This is a test. I am not seeing twts from @stigatle@yarn.stigatle.no and it seems like @prologic@twtxt.net might not be seeing twts from me. Do people see this?

@prologic@twtxt.net Hitting that URL returns a bunch of HTML even though there is no user named lovetocode999 on my pod. I think it should 404, and maybe with a delay, to discourage whatever this abuse is. Basically this can be used to DDoS a pod by forcing it to generate a hunch of HTML just by doing a bogus GET like this.

I’m seeing GETs like this over and over again:

"GET /external?nick=lovetocode999&uri=https://vuf.minagricultura.gov.co/Lists/Informacin%20Servicios%20Web/DispForm.aspx?ID=8375144 HTTP/1.1" 200 35861 17.077914ms

always to nick=lovetocode999, but with different uris. What are these calls?

@prologic@twtxt.net Inspect? What’s sift? What would you like to know about the files?

@prologic@twtxt.net I’m still getting this crap:

Something like 100 Gbytes of this junk has accumulated since I updated and re-started the server. I’m now running the latest version of yarnd, so the update did not fix the problem. Something else is going wrong.

How are temporary files growing to 10 Gbytes in size? The name of the file is “yarn-avatar”, but why would avatars be so large?

@prologic@twtxt.net Sure, but why would this start happening all of a sudden today? Nothing like this has happened before. Is this a known bug?

@prologic@twtxt.net 0.15.1, looks like.

@bender@twtxt.net I hope so too. I’ve never seen anything like this before. Whatever it is, it’s strange.

Hack of the day: running watch -n 60 rm -rf /tmp/yarn-avatar-* in a tmux because all of a sudden, without warning, yarnd started throwing hundreds of gigabytes of files with names like yarn-avatar-62582554 into /tmp, which filled up the entire disk and started crashing other services.

This is completely insane!

abucci@buc:/tmp$ du -sh /tmp/yarnd-avatar-*
564M    /tmp/yarnd-avatar-3024946878
7.2G    /tmp/yarnd-avatar-3122347915
11G     /tmp/yarnd-avatar-3533381443
445M    /tmp/yarnd-avatar-441914658

I’m going to have to shut down my server soon. This looks like some kind of DDoS. Whether intentional or not it’s filling up the disk at an unsustainable rate.

@prologic@twtxt.net This is weird, but today, out of nowhere, yarnd filled up the disk on the VPS where I run it. It’s never done anything like this before and I have no idea why it would start. But it threw almost 700 Gbytes of data into /tmp in files like this:

164 files. Some are empty, some are 7 or even 10 Gbyte.

Any idea what would cause that? And why now, after running yarnd for so long with nothing like this happening?

i imagine this is the agreement that the lower plebs are stuck in. Larger enterprise accounts wont fall under these agreements. When I worked a hospital we would get agreements like this with contracts and the legal would line out things like this add new language and send them back.

@movq@www.uninformativ.de Somewhere or another, I think in a William Byrd talk, I heard it suggested that the best ideas in computer science should fit on an index card (ah yes it’s this one: https://paperswelove.org/2017/video/will-byrd-most-beautiful-program/ ). He was referring to the basic principles of LISP/the lambda calculus, which have sometimes been called the Maxwell’s equations of computer programming (by Alan Kay). Simple, short, elegant, but very densely packed with meaning–generations of people have spent their whole careers unpacking what those simple rules can do.

Much of modern software feels like the polar opposite of that. Not only can you not write it on an index card, you never will be able to because people who write software don’t seem to aspire to try. I wish more people thought this way though!

I feel like complexity is measured differently at different levels of a project..

• at the function level you use cyclomatic complexity or how many branches internally and how much you need to keep in mind as it calls out to other functions.
  
• at a file/module level is a balance of the module doing too much against being so granular that you have cross dependency across modules. I have trouble with keeping things dry at this level because it can lead to parts being so abstract or generalized that it adds complexity.
  
• at a project level i suppose its a matter of how coupled things are across sub-modules.
