Dear hard working cloudflare sysadmin,

above is a mail which was send to me as text/plain attachement. Please escalate that issue: This E-Mail is nearly unreadable!

Please make sure, that further E-Mails are send better readable, especially, if you want that people read E-Mails.

Please also send me the internal ticketnumber. I will be onsite during summer, and will check the progress.

Thanks in advance, Bastian Bittorf / greeting from germany


I will talk to the team.


Of course this possible and working:

https://openwrt.org/docs/guide-user/network/wifi/roaming

Follow the usteer path.


This seems a bit like saying “want to play pong on your gaming machine? All the groundwork has been laid and you can type apt install gcc. We even package SDL.”

Those docs convince me that someone has tried this and written some software, not that it’s anything like fully supported. Also, the same setup should get 802.11r, not just k and v.


802.11r is useless on a typical home network, as Windows does not implement it for WPA2/WPA3 Personal. It is only useful on WPA2/WPA3 Enterprise networks; sadly, OpenWrt fails at that: https://forum.openwrt.org/t/wpa3-enterprise-with-ft-needs-fi...


I tried usteer on my recent wifi rebuild/updates, and I am for sure sticking with good old DAWN instead. https://openwrt.org/docs/guide-user/network/wifi/dawn

DAWN wasn't flawless out of box about choosing bands, and would sometimes trash a bit... but it generally worked great for the 3x r7800's I had. And it would generally help band steer people to 5ghz in useful ways.

Usteer has everyone packed onto 2.4GHz. With very rare exception. It just doesn't seem to bandsteer well at all, in my view.

Agreed that this should be a top priority, so so much. Bandsteer and multi-AP are very similar problem-sets; even if users only have a single AP they need good steering to have a good experience. DAWN has started making that a reality (well before usteer) and continues to be the only viable open source option for people right now.


At least it gives some numbers and point in a direction:

  $ hyperfine --warmup 3 './hello-world-bin-sh.sh' './hello-world-env-python3.py'
  Benchmark 1: ./hello-world-bin-sh.sh
    Time (mean ± σ):       1.3 ms ±   0.4 ms    [User: 1.0 ms, System: 0.5 ms]
  ...
  Benchmark 2: ./hello-world-env-python3.py
    Time (mean ± σ):      43.1 ms ±   1.4 ms    [User: 33.6 ms, System: 8.4 ms]
  ...


Something seems wrong im this article. The side-by-side comparison shows 4 formats:

  · Original PNG image (2.6 MB)
    · Name "high_fidelity.png", but in fact 298.840 bytes and format: JPEG
  · JPEG XL (default settings, 53 KB): indistinguishable from the original
    · Name "high_fidelity.png.jxl.png", but in fact 3.801.830 bytes and format: PNG
  · WebP (53 KB): some mild but noticeable color banding along with blurry text
    · Name "high_fidelity_webp.png", but in fact 289.605 bytes and format PNG
  · JPEG (53 KB): strong color banding, halos around the text, small text hard to read
    · Name "jpeg_high_fidelity.jpg", but in fact 52.911 bytes and format JPEG
The comparison does not make any sense, everything is just wrong. Also when encoding the large original PNG image to AVIF, it has only 20.341 Bytes with no visual change, see: http://intercity-vpn.de/files/2024-10-27/upload/


PNG is lossless so they are using it to display compression artifacts of formats that may not have had wider browser support.


> high_fidelity.png.jxl.png

means the original was

- loss-converted to JXL, measured as 53k

- then losslessly converted to PNG to be displayed on the website


52 911 bytes instead of 53 kB is really not that far off.

And your AVIF is certainly not without visual changes. The colours are off and there is visible ringing.


you are right, i changed it to "acceptable visual changes".


> "jxl.png", but in fact 3.801.830

I guess that is because the noise from the lossy encoding creates more entropy, that then has to be losslessly encoded as PNG, which pushes the files size above the original?


It says "optimized", but those pages seems to be very slow. First try on the showcase(!) gives only 55% on performance:

from https://en.wikipedia.org/wiki/Retrieval-augmented_generation

"Retrieval augmented generation (RAG) is a type of information retrieval process. It modifies interactions with a large language model (LLM) so that it responds to queries with reference to a specified set of documents, using it in preference to information drawn from its own vast, static training data."


1 TW needs an area of 173 x 173 Km = ~30.000 Km².

These are 0.02% of the earth landmass.

Values are like this, when calculating conservative: 1 KWp needs an area around 10m². For enough maintenance distance multiply by 3 = 30m².

  => 1 Megawatt = 3 * 10m² * 1000 = 30.000m².
  => 1 Gigawatt = 3 * 10m² * 1000 * 1000 = 30.000.000m².
  => 1 Terawatt = 3 * 10m² * 1000 * 1000 * 1000 = 30.000.000.000m².
Square root of 30.000.000.000m² = 173205m = 173Km. According to statista.com, the total earth landmass is 149.000.000 Km², so 30.000m² are 0.02% auf 149 million Km².


"That year (1995) was also when Linux was first ported to a new architecture by Linus. He'd been given a DEC Alpha machine."

This is not fully correct: The first port ever was on Motorola M68k in 1993 for the Amiga platform.

https://www.tech-insider.org/linux/research/1993/0915.html


I think the Alpha port stands out in memory because that was the cause for overcoming 32-bitness.


it is 'Widevine'
