Intel Core Ultra 7 255H Linux CPU Performance
Lenovo recently sent over their new ThinkPad P1 Gen 8 laptop for review under Linux. My Linux review on that ThinkPad P1 Gen 8 laptop will be coming up in the near future along with some other benchmarks from that premium mobile workstation. But with this being the first time I’ve had an Intel Core Ultra 7 255H “Arrow Lake H” device at Phoronix, here are some standalone benchmarks looking at the CPU performance of that 16-core mobile processor compared to vario

All good things come to an end, I guess.

I have an Epson printer (AcuLaser C1100) and an Epson scanner (Perfection V10), both of which I bought about 20 years ago. The hardware still works perfectly fine.

Until recently, Epson still provided Linux drivers for them. That is pretty cool! I noticed today that they have relaunched their driver website – and now I can’t find any Linux drivers for that hardware anymore. Just doesn’t list it (it does list some drivers for Windows 7, for example).

I mean, okay, we’re talking about 20 years here. That is a very long time, much more than I expected. But if it still works, why not keep using it?

Some years ago, I started archiving these drivers locally, because I anticipated that they might vanish at some point. So I can still use my hardware for now (even if I had to reinstall my PC for some reason). It might get hacky at some point in the future, though.

This once more underlines the importance of FOSS drivers for your hardware. I sadly didn’t pay attention to that 20 years ago.

↳ In-reply-to » Xfce does one thing very right: It stores its settings in plain-text XML files. This allows me to easily read, track, and maybe even distribute these settings to other machines.

@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz I spent so much time in the past figuring out if something is a dict or a list in YAML, for example.

What are the types in this example?

items:
- part_no:   A4786
  descrip:   Water Bucket (Filled)
  price:     1.47
  quantity:  4
- part_no:   E1628
  descrip:   High Heeled "Ruby" Slippers
  size:      8
  price:     133.7
  quantity:  1

items is a dict containing 
 a list of two other dicts? Right?

It is quite hard for me to grasp the structure of YAML docs. 😱

The big advantage of YAML (and JSON and TOML) is that it’s much easier to write code for those formats, than it is with XML. json.loads() and you’re done.

Saw this on Mastodon:

https://racingbunny.com/@mookie/114718466149264471

18 rules of Software Engineering

  1. You will regret complexity when on-call
  2. Stop falling in love with your own code
  3. Everything is a trade-off. There’s no “best” 3. Every line of code you write is a liability 4. Document your decisions and designs
  4. Everyone hates code they didn’t write
  5. Don’t use unnecessary dependencies
  6. Coding standards prevent arguments
  7. Write meaningful commit messages
  8. Don’t ever stop learning new things
  9. Code reviews spread knowledge
  10. Always build for maintainability
  11. Ask for help when you’re stuck
  12. Fix root causes, not symptoms
  13. Software is never completed
  14. Estimates are not promises
  15. Ship early, iterate often
  16. Keep. It. Simple.

Solid list, even though 14 is up for debate in my opinion: Software can be completed. You have a use case / problem, you solve that problem, done. Your software is completed now. There might still be bugs and they should be fixed – but this doesn’t “add” to the program. Don’t use “software is never done” as an excuse to keep adding and adding stuff to your code.

A bill from our ISP in 1998.

We’re talking about a month here, 1998-07-27 to 1998-08-26.

Basic fee: 7.50 DM (about 6€ today).

Online time: 516 minutes, 23.53 DM (about 20€ today).

That’s just the ISP costs, if I’m not mistaken. The underlying phone calls were pretty pricey as well.

Finally I propose that we increase the Twt Hash length from 7 to 12 and use the first 12 characters of the base32 encoded blake2b hash. This will solve two problems, the fact that all hashes today either end in q or a (oops) 😅 And increasing the Twt Hash size will ensure that we never run into the chance of collision for ions to come. Chances of a 50% collision with 64 bits / 12 characters is roughly ~12.44B Twts. That ought to be enough! – I also propose that we modify all our clients and make this change from the 1st July 2025, which will be Yarn.social’s 5th birthday and 5 years since I started this whole project and endeavour! đŸ˜± #Twtxt #Update

@eapl.me@eapl.me here are my replies (somewhat similar to Lyse’s and James’)

  1. Metadata in twts: Key=value is too complicated for non-hackers and hard to write by hand. So if there is a need then we should just use #NSFS or the alt-text file in markdown image syntax ![NSFW](url.to/image.jpg) if something is NSFW

  2. IDs besides datetime. When you edit a twt then you should preserve the datetime if location-based addressing should have any advantages over content-based addressing. If you change the timestamp the its a new post. Just like any other blog cms.

  3. Caching, Yes all good ideas, but that is more a task for the clients not the serving of the twtxt.txt files.

  4. Discovery: User-agent for discovery can become better. I’m working on a wrapper script in PHP, so you don’t need to go to Apaches log-files to see who fetches your feed. But for other Gemini and gopher you need to relay on something else. That could be using my webmentions for twtxt suggestion, or simply defining an email metadata field for letting a person know you follow their feed. Interesting read about why WebMetions might be a bad idea. Twtxt being much simple that a full featured IndieWeb sites, then a lot of the concerns does not apply here. But that’s the issue with any open inbox. This is hard to solve without some form of (centralized or community) spam moderation.

  5. Support more protocols besides http/s. Yes why not, if we can make clients that merge or diffident between the same feed server by multiples URLs

  6. Languages: If the need is big then make a separate feed. I don’t mind seeing stuff in other langues as it is low. You got translating tool if you need to know whats going on. And again when there is a need for easier switching between posting to several feeds, then it’s about building clients with a UI that makes it easy. No something that should takes up space in the format/protocol.

  7. Emojis: I’m not sure what this is about. Do you want to use emojis as avatar in CLI clients or it just about rendering emojis?

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.

Imagine I found this twt one day at https://example.com/twtxt.txt :

2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup

Image

and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to

2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory

Image

which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)

That’s what I meant by “spoofing” in an earlier twt.

I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.

Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.

Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.

↳ In-reply-to » 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.

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?
