@bender@twtxt.net haha funny! though i just realized my ISP is the only one with fiber pulled to the property so i would have to get a phone line from them some how. The other ISP in the area is basically a mobile hotspot.

Hey so.. i just got an email from my ISP saying they will terminate my service. Did i break something @abucci@anthony.buc.ci ?

@prologic@twtxt.net Yes, I can do that.

@stigatle@yarn.stigatle.no @prologic@twtxt.net my /tmp is also fine now! Thanks for your help @prologic@twtxt.net!

@prologic@twtxt.net I unbanned a few IP address I had blocked before the bugfix. I wasn’t being careful and just blocked any IP I saw making a large number of requests to my pod. That slowed the problem down but I think I blocked your and @stigatle@yarn.stigatle.no ’s pods in the process, oops.

@stigatle@yarn.stigatle.no Sweet, thank you! I’ve been shooting myself in the foot over here and want to make sure the situation is getting fixed!

@stigatle@yarn.stigatle.no @prologic@twtxt.net testing 1 2 3 can either of you see this?

@prologic@twtxt.net I don’t know if this is new, but I’m seeing:

Jul 25 16:01:17 buc yarnd[1921547]: time="2024-07-25T16:01:17Z" level=error msg="https://yarn.stigatle.no/user/stigatle/twtxt.txt: client.Do fail: Get \"https://yarn.stigatle.no/user/stigatle/twtxt.txt\": dial tcp 185.97.32.18:443: i/o timeout (Client.Timeout exceeded while awaiting headers)" error="Get \"https://yarn.stigatle.no/user/stigatle/twtxt.txt\": dial tcp 185.97.32.18:443: i/o timeout (Client.Timeout exceeded while awaiting headers)"

I no longer see twts from @stigatle@yarn.stigatle.no at all.

@prologic@twtxt.net Have you been seeing any of my replies?

@abucci@anthony.buc.ci / @abucci@anthony.buc.ci Any interesting errors pop up in the server logs since the the flaw got fixed (unbounded receieveFile())? 🤔

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 I am not seeing twts from @stigatle@yarn.stigatle.no anymore. Are you seeing twts from me?

@prologic@twtxt.net

./tools/dump_cache.sh: line 8: bat: command not found
No Token Provided

I don’t have bat on my VPS and there is no package for installing it. Is cat a reasonable alternate?

@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.

@stigatle@yarn.stigatle.no I used the following hack to keep my VPS from running out of space: watch -n 60 rm -rf /tmp/yarn-avatar-*, run in tmux so it keeps running.

@stigatle@yarn.stigatle.no / @abucci@anthony.buc.ci My current working theory is that there is an asshole out there that has a feed that both your pods are fetching with a multi-GB avatar URL advertised in their feed’s preamble (metadata). I’d love for you both to review this PR, and once merged, re-roll your pods and dump your respective caches and share with me using https://gist.mills.io/

@prologic@twtxt.net There are a lot of logs being generated by yarnd, which is something I haven’t seen before too:

I’ve seen that nick=lovetocode999 a bunch.

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

@prologic@twtxt.net 10 Gbytes has accumulated since I made that last post. It’s coming in at a rate of 55 Mbits/second !

@prologic@twtxt.net I think there’s more to it than that. I’ve updated, yet hundreds of gigabytes of junk is still accumulating.

@prologic@twtxt.net Alright, running yarnd 0.15.1 now. I stopped my hack so we’ll see if the VPS gets clogged with junk 😆

@prologic@twtxt.net

abucci@buc:~/yarnd/yarn$ make preflight

🤔

@prologic@twtxt.net Aha, got it. Thanks for looking into it. I’m updating now and we’ll see if that stops it.

@stigatle@yarn.stigatle.no Works now! 🥳

@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.

@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?

@lyse@lyse.isobeef.org I bet it was! These kinds of sunset shots (with colorful delicious clouds in motion… etc) have always been candy to my eyes. And I know for a fact that the real thing usually looks ten folds better than in pictures (at least in the ones I used to take). Thank you for sharing these!

@movq@www.uninformativ.de

(I don’t really trust Android, though, and I suspect that apps can still install background services that are always active. Pure speculation and paranoid on my part, but still.)

Which is fair, but I would say the GrapheneOS devs in particular are also quite paranoid about this stuff and go to great pains to make sure this stuff can be controlled by the user.

@prologic@twtxt.net Yeah that is probably what was happening. I wish that go build could embed the values that go install does.

@abucci@anthony.buc.ci i love this talk

@movq@www.uninformativ.de This outage did affect me, though not much, via the university where my wife teaches and where I teach sometimes. They actually sent out an alert in their emergency alert system (the one they use to alert people of extreme weather events and bomb threats, mostly), telling people that all IT systems were down.

A friend of mine elsewhere pointed out that they pushed this change on a Friday, which of course no software developer with any experience would ever, ever, ever do. I have to assume there’s some toxic management at CrowdStrike, but who knows. Even more reasons to sympathize with the poor folks who are probably going to be working nights and weekends to clean up this mess.

@prologic@twtxt.net One of these days I’ll turn off registrations

@prologic@twtxt.net Hello!

@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!

@New_scientist@feeds.twtxt.net No.

@New_scientist@feeds.twtxt.net It’s insane that a single botched software update can have worldwide impact. We’ve messed up badly.

@prologic@twtxt.net LOL Thanks to you, even I started using signal.

@movq@www.uninformativ.de TBH I don’t like Matrix… It feels a bit messy, my conversations and servers I join tend to get mangled, some stuff tend to have some sub-stuff… etc. I don’t hate it though, because I know I may have been using it wrong.

But hey, have you ever tried Databag ? Your family might get a better user experience with this one.

@movq@www.uninformativ.de Don’t give up.

What about Signal? I’m had great success with this, friends, family, neighboards. They get it. It works. I don’t have to worry about it too much.

@xuu@txt.sour.is I have a theory as to why your pod was misbehaving too. I think because of the way you were building it docker build without any --build-arg VERSION= or --build-arg COMMIT= there was no version information in the built binary and bundled assets. Therefore cache busting would not work as expected. When introducing htmx and hyperscript to create a UI/UX SPA-like experience, this is when things fell apart a bit for you. I think….

@hecanjog@hecanjog.com Enjoy it while it lasts… it’s been hot as hell in here in the last couple of days.

@johanbove@johanbove.info Did they produce a new season or you’re just catching up with the old ones? It has been ages since the last time I’ve watched any of it.

@prologic@twtxt.net hey testing a rebuild of yarnd

@prologic@twtxt.net Well ain’t that grand? I’ll get it updated

By the way, @xuu@txt.sour.is, it looks like you’re running an old, buggy version of yarnd, that duplicates twts in the feed on edit.
