Sweepi··on EU Member States (and Google) suddenly want to keep cookie banners
The origin story of the "EU" cookie banner:

  1. Proposal: Lets ban tracking.
  2. "But what if the user wants to be tracked? People want better adds![1] We are also missing out on business innovations!"
  3. Fine. But since nobody in their right mind would want to done to them, you must prove with out a shadow of a doubt that the people you are tracking did consent to that.
  4. Surely, nobody will do this.
  5. Cookie banners everywhere.
[1] I am not kidding. "Isnt it better if the ads show things you are interested in?" was a main talking point.

Bonus: The original proposal (~2017) also mandated that social media which uses personal algorithmic feeds must make the individual data set of each user which is used to generated said feed viewable and editable to the user. Was ofc shut down by the corporate bootlickers people tend to vote into our parliaments.

Sweepi··on The AirPods Effect
I think "Your Brain Needs Idle Time" is more important than the effect on random social interactions.
Sweepi··on Linux latency measurements and compositor tuning
These vertical labels make me unreasonably mad.

GE 10.34 released March 23th, 5 days after 10.33 - any reason to test with 10.33 in June? Was there a regression?

Sweepi··on Zig Structs of Arrays (2024)
OT: I just spend a few minutes searching for the source of the "Not all CPU operations are created equal" slide of the linked presentation (Andrew Kelley - Practical DOD), its here:

Sweepi··on JLink JTAG Access on the Pinecil
Good to see an "organic" J-Link + RISC-V use case :)
Sweepi··on A 10 year old Xeon is all you need
"-t 8 matches physical cores. The machine has 16 SMT threads but only 8 cores. On a memory-bound workload, oversubscribing threads adds scheduling cost without adding throughput: the cores are waiting on DDR3, not on each other."

But ... isnt that a classic use case for SMT? Giving T1 sth. to do while T0 is waiting on DDR(3) and vise-versa?

I also dont understand the explanation of "--cpu-moe". If an expert has ~ 4.0 GiB of Parameters, why does optimizing the sequence of experts minimize cash trashing? With 20 MiB of L3 Cash vs 4.0 GiB of Parameters, it wont cash any noticeable amount of the Parameters, will it?

As mentioned by others, only some Intel Xeon E5-2xxx v4 did support DDR3, and according to Intel, the E5-2620 v4 is not one of them.

Sweepi··on The Problem with the Ferrari Luce EV Offers a Lesson for Every Leader
Regarding "The exterior looks like an iPad since Jony Ive designed it":

Marc Newson is also on the team, and there striking similarities to (t)his 27 year old concept car[1]: https://marc-newson.com/ford-021c-concept-car/

Regarding the UI: This is miles ahead of any other digital cockpit made by Ferrari. Also pretty good overall.

Sweepi··on Flatpak Will Depend on Systemd
Title should be "Flatpack 2.0 considered to be depended on Systemd"
Sweepi··on Why the smart home bubble popped
The market needs competition.

Apple has this reasonable offer:

  - Buy an Homepod/Apple TB as a home station
  - Everything works locally, even the internet is down.
  - no Accounts. 
  - only one privacy policy: Apple's
  - but ofc, you can control everything remote, and Apple makes sure its easy and secure.

Since its Apple, they have to make sure there are downsides, too (beside price):

  - If Apple does not deem it worthy, it will not get implemented. [1]
  - Things that should be simple are not. Try to set the lights to turn on 10 minutes before your alarm goes off. I'll wait here.
I see a market for a company which builds on home-assistant. You can tell the nerds: If "corporate" does sth you dont like, you can always go back to home-assistant. And for everybody else, you can offer a support, a list of compatible/certified devices, an extendable, open API, a vetted applications/script market place, a secure remote connection, ...

[1] It has been a few years, but last time I checked, CO2 Levels still can only be reported as labeled Levels ("high/low/.."), with the actually ppm Value hidden in some auxiliary value. No way around it, Apple needed to put CO2{ type: integer, range: 0-10000} in some json some where, and they did not come around to do it for like half a decade, at which point I stopped caring.

Sweepi··on GitHub confirms breach of 3,800 repos via malicious VSCode extension
Answer: Because the "random stuff" (plugins for VS Code and other IDEs) solves real problems and nothing bad happens most of the time.

Almost no manager will sign-off spending time on building stuff in-house if its available "for free".

This is also in no way a new thing. How much code was written in notepad++ in the '00ies? Did anyone bother to check if the plugins did sth. malicious? We also used some weird closed-src "addon" for the Nullsoft installer to get a product out of the door, dont remember what the problem was exactly....

Sweepi··on Enabling Resizable Bar on RTX 3080 Vbios via GitHub
Not reading that AI slop, if you need to flash the VBIOS of 3080 (or any GPU), do the following:

  1. Get a new VBIOS from a trusted source. I recommend TPU[1], they have a HUGE collection.
  2. Backup the current VBIOS (e.g. GPU-Z has a on-click option to backup and upload it to TPU)
  3. Have a working 2nd GPU[2] (or another PC with a free PCIe slot) so that you have the option the flash back the orignal VBIOS in case things go south [3]
  4. Test that your backup GPU/PC works BEFORE flashing any VBIOS, goddamit!
[1] https://www.techpowerup.com/vgabios/?architecture=&manufactu...

[2] onboard/iGPU is sufficient if present, but again: test if it works before doing anything! (just remove the dGPU and see if you get video output)

[3] Ofc you can also try to memorize the key inputs to do it blindly w/o video output from your GPU. Not recommended.

Sweepi··on Make zip files smaller with zip shrinker
so this tool: - Strips away comments, metadata and directories(!!) - re-compresses the data with deflate (on presumably higher setting)

makes me feel uneasy that sth. which does lossy compression(metadata is lost) is called "ZIP Shrinker". Hope nobody gets surprised by this.

The real solution is to use lzma(2).

Sweepi··on New accessibility features powered by Apple Intelligence
dont you worry, as a sighted person I am also infuriated by apples slooow reading speed, e.g. for "Announce Notifications".
Sweepi··on US bill proposes new national EV tax, while some push to slash gas tax to zero
"Obviously EVs currently account for a small fraction of road use right now, but they mostly drive on dense, urban infrastructure - the most expensive to build and maintain."

Is it the most expensive by $/length of road, or by $/(vehicle * travel distance)?

Sweepi··on Linux security mailing list 'almost unmanageable'
"Torvalds' remarks contrast with recent comments from fellow kernel maintainer Greg Kroah-Hartman, who recently told The Register that AI has become an increasingly useful tool for the FOSS community."

Does it? Both points can be true at the same time.

Sweepi··on Heat pump sales rise across Europe

Strong words.

R-290(propane) and R-744 (carbon dioxide) both have a Ozone depletion potential(ODP) of 0. What are you talking about?

any current articles on that topic?

Sweepi··on Mystery Cpuid Bit
And people say "never read the comments":

CL says: April 20, 2026 at 9:18 pm

I updated sandpile.org to reflect that

  Bit 19 = MP-capable
  Bit 18 = ECC-capable
Those were two distinct capabilities.

[sources: K7 µcode + K8 XOS-based public simulator published in 2000 + I worked at AMD back then]

Sweepi··on A quick look at Mythos run on Firefox: too much hype?
> Conclusion

"The Firefox 150 data suggests a tool that is genuinely useful for defensive security work, especially at scale, but the public record does not justify the strongest claims people want to make from it. The headline number is impressive, yet it bundles together bugs of very different significance and does not publicly resolve into a clean accounting."

I mean: Obviously. Does not matter how good or bad a product is, the current meta is to over-hype it in order to achieve maximum "news-penetration". Anthropic seems to have sth. "real". However, Since there is no way for outsiders to calculate real metrics like false-positive rate, cost (tokens, Dev hours for setup and review, ...)/ Issue found, ... there is no real way to put any scale on the hype-graph.

Sweepi··on Framework Laptop 13 Pro
If anything brakes on the Framework, you get all the docs you need to attempt a repair yourself, also spare parts are available, also, you can upgrade SSD/RAM/Mainboard and ports.

Apple: Every repair is Mainboard replacement and costs 70% of the used value of the Notebook. Upgrades are impossible. Have a nice day!

Sweepi··on XOR'ing a register with itself is the idiom for zeroing it out. Why not sub?
"Bonus bonus chatter: The xor trick doesn’t work for Itanium because mathematical operations don’t reset the NaT bit. Fortunately, Itanium also has a dedicated zero register, so you don’t need this trick. You can just move zero into your desired destination."

Will remember for the next time I write asm for Itanium!

Sweepi··on In the UK, EVs are cheaper than petrol cars, thanks to Chinese competition

Sweepi··on Smoking ban for people born after 2008 in the UK agreed
Sounds a like next century problem to me.
Sweepi··on Smoking ban for people born after 2008 in the UK agreed
"they're banning nicotine products" If I am not mistaken, they are banning to sale of tobacco, not nicotine:

"[..]provision prohibiting the sale of tobacco to people born on or after 1 January 2009[..]"

"I also really doubt that they will legalise weed and then say "but of course you're not allowed to smoke it, edibles only"."

I mean, there is still vaporization, so it wouldn't be edibles only?

Sweepi··on Smoking ban for people born after 2008 in the UK agreed
>This is a clear restriction on liberty.

So is banning the sale of leaded gasoline.

Sweepi··on Smoking ban for people born after 2008 in the UK agreed
iirc alcohol is the drug with the highest amount of 3rd party harm due to the high number of people beating their spouse, children and sometimes random strangers under the influence. (+ 3rd party property, car crashes, ...) Keep in mind this was evaluated with current laws, which bans most kinds of indoor-smoking.

Still a good idea to ban cigarettes and force people to consume their nicotine in healthier ways.

Sweepi··on Smoking ban for people born after 2008 in the UK agreed
Newsflash: Its possible to consume "marijuana" w/o smoking it (just like nicotine!).
