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 Iâve had an Intel Core Ultra 7 255H âArrow Lake Hâ device at Phoronix, here are some standalone benchmarks looking at the CPU performance of that 16-core mobile processor compared to vario ⊠â Read more

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 â and now I canât find any Linux drivers for that hardware anymore. Just doesnât list it (it does list some drivers for Windows 7, for example).
I mean, okay, weâre 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 didnât pay attention to that 20 years ago.
@prologic@twtxt.net No, this is a Linux manpage from the man-pages project: https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/tree/man/man7/ascii.7
I do have an idea whatâs going on. Could be an unfortunate interaction between the table preprocessor tbl and the man macro package. đ€
mandoc is nicer to read/write than the man macro package and, most importantly, itâs semantic markup.
HTML output is a bit broken in GNU groff, though (OpenBSD on the left, GNU on the right):

Still, Iâm inclined to convert my manpages to mandoc.
@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. đą
The big advantage of YAML (and JSON and TOML) is that itâs much easier to write code for those formats, than it is with XML. json.loads() and youâre done.
Saw this on Mastodon:

18 rules of Software Engineering
- You will regret complexity when on-call
- Stop falling in love with your own code
- Everything is a trade-off. Thereâs no âbestâ 3. Every line of code you write is a liability 4. Document your decisions and designs
- Everyone hates code they didnât write
- Donât use unnecessary dependencies
- Coding standards prevent arguments
- Write meaningful commit messages
- Donât ever stop learning new things
- Code reviews spread knowledge
- Always build for maintainability
- Ask for help when youâre stuck
- Fix root causes, not symptoms
- Software is never completed
- Estimates are not promises
- Ship early, iterate often
- 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 â but this doesnât âaddâ to the program. Donât use âsoftware is never doneâ as an excuse to keep adding and adding stuff to your code.

FWIW, another thing I often use is !! to recall the entire previous command line:
$ find -iname '*foo*'
./This is a foo file.txt
$ cat "$(!!)"
cat "$(find -iname '*foo*')"
This is just a test.
Yep!
Or:
$ ls -al subdir
ls: cannot open directory 'subdir': Permission denied
$ sudo !!

A bill from our ISP in 1998.
Weâre 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).
Thatâs just the ISP costs, if Iâm 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) đ
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! â I also propose that we modify all our clients and make this change from the 1st July 2025, which will be Yarn.socialâs 5th birthday and 5 years since I started this whole project and endeavour! đ± #Twtxt #Update
Anyone watching/watched Black Mirror Season 7? đ”âđ«đ” Iâve been watching the first episode and a couple of minutes into the third act then I was like ⊠Oh boy, I need a break! Theyâre just so Fu__ing good, Iâll give them that!
@javivf@adn.org.es having the extension listed means that it has been discussed and, usually implemented. Now, number 6 and 7 on the list as its stands today are not supported by any of the known clients. I believe their (again, 6 and 7) inclusion on the list has been precipitated, and lax.
neat! my watcher is currently sitting at about 75 MB following over 1500 feeds. only about 200 are currently somewhat active.

@eapl.me@eapl.me here are my replies (somewhat similar to Lyseâs and Jamesâ)
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
if something is NSFWIDs 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.
Caching, Yes all good ideas, but that is more a task for the clients not the serving of the twtxt.txt files.
Discovery: User-agent for discovery can become better. Iâm working on a wrapper script in PHP, so you donât 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 thatâs the issue with any open inbox. This is hard to solve without some form of (centralized or community) spam moderation.
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
Languages: If the need is big then make a separate feed. I donât 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 itâs about building clients with a UI that makes it easy. No something that should takes up space in the format/protocol.
Emojis: Iâm not sure what this is about. Do you want to use emojis as avatar in CLI clients or it just about rendering emojis?

Subject: The [tag URI scheme](https://en.wikipedia.org/wiki/Tag_URI_scheme) looks interesting. I like that it human read- and writable. And since we already got the timestamp in the twtxt.txt it would be

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but hereâs 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 â$HOMEâ /mnt/backup
and I responded with â(#5dgoirqemeq) Thanks for the tip!â. Then Iâve endorsed the twt, but it could latter get changed to
2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory
which also has an 11-character base32 hash of 5dgoirqemeq. (Iâm using the existing hashing method with https://example.com/twtxt.txt as the feed url, but Iâm taking 11 characters instead of 7 from the end of the base32 encoding.)
Thatâs what I meant by âspoofingâ in an earlier twt.
I donât 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 âtwo timesâ is because of the birthday paradox.
Side note: current hashes always end with âaâ or âqâ, 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.
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.
@prologic@twtxt.net Iâm still getting this crap:

Something like 100 Gbytes of this junk has accumulated since I updated and re-started the server. Iâm 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 âyarn-avatarâ, but why would avatars be so large?
This is completely insane!
abucci@buc:/tmp$ du -sh /tmp/yarnd-avatar-*

Iâm going to have to shut down my server soon. This looks like some kind of DDoS. Whether intentional or not itâs 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. Itâs 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:
