(11 Dec) How To Know If You’re The Baddies: A Metric For Evil People

Without touching a penny of their existing wealth, while still leaving $500,000 per year income each, the top 1% in America could raise everyone above the poverty line 3,781 times over.

We discovered the ELIZA Effect 50+ years ago.

en.wikipedia.org/wiki/ELIZA_ef

Yet we're still SO desperate to believe we've arrived at actual "artificial intelligence." (Maybe someday. But so far, bullshit extruded by con men and spread by fools.)

Let's distinguish today's painfully fake "AI" from someday-real AI by calling the former "AIIIEEEEEE!"

Like "This exciting (= mega-profitable) update is powered by our fabulous (= not true) hot (= planet-burning) new AIIIEEEEEE."

Oh hey, there is a still in use Dell latitude Xp from 1994 with built in trackball and 3.5 inch floppy built in, still in active use at work! From the dust on the keyboard, it’s barely in use… but it would cause a “world of hurt” if it was to die.

Linux 6.15 will support ASUS Zenbook A14

ASUS Zenbook A14 is an ARM64-based laptop that uses the powerful Qualcomm Snapdragon X chipset (either X1-26-100 or X1P-42-100 with 45 TOPS). ASUS considers it as a Copilot+ PC that weighs under 1 kg and promises up to 32 hours of battery life. The laptop features a 1920×1200 14-inch OLED display, 16 GB or 32 GB of LPDDR5X RAM, and 512 GB or 1 TB of NVMe storage. It runs Windows 11 as a primary operating system.

As for the chassis, the Ceraluminum chassis is a military-grade US MIL-STD 810H standard to ensure that your laptop is the toughest. Right now, it only supports Windows, but open source developers are working towards opening support for this laptop to run Linux efficiently.

Linux 6.15 ensures that this happens by adding support for this laptop. Right now, support is similar to other Snapdragon X1-based laptops, which means that the following features are not expected to work: (listed below is the abovementioned laptop in this case)

  • Audio (Speakers/microphones/headphone jack)
  • Camera (OmniVision OV02C10)
  • HDMI (Parade PS185HDM)
  • EC

The following features have been added to support said laptop as of this patch series:

  • Keyboard
  • Touchpad
  • NVME
  • Lid switch
  • Camera LED
  • eDP (FHD OLED, SDC420D) with brightness control
  • Bluetooth, WiFi (WCN6855)
  • USB Type-A port
  • USB Type-C ports in USB2/USB3/DP (both orientations)
  • aDSP/cDPS firmware loading, battery info
  • Sleep/suspend, nothing visibly broken on resume

However, the key differences were:

  • Wifi/Bluetooth combo being Qualcomm FastConnect 6900 on UX3407QA and Qualcomm FastConnect 7800 on UX3407RA
  • USB Type-C retimers are Parade PS8833, appear to behave identical to Parade PS8830
  • gpio90 is TZ protected

However, those additions are currently under review and will land to the main Linux 6.15 branch once accepted.

Linux 6.15’s exFAT file deletion performance boosted

A recent development in the upcoming Linux 6.15 kernel has been spotted, because there was a big improvement to the exFAT file system implementation in relation to how it deletes the files when the “discard” mount option is used. This improvement significantly saves time as a test file after the merge has been deleted in 1.6 seconds, compared to more than 4 minutes of the total time taken.

This pull request makes sure that, upon file deletion, it discards a group of contiguous clusters (that is, clusters that are next to each other) in batch instead of discarding them one by one. This was because in prior kernels, such as 6.14, “if the discard mount option is enabled, the file’s clusters are discarded when they are freed. Discarding clusters one by one will significantly reduce performance. Poor performance may cause soft lockup when lots of clusters are freed.”

The change has been introduced in commit a36e0ab. Since then, the pull request has been merged to the kernel and it will be integrated to the first release candidate of Linux 6.15. A simple performance benchmark has been verified with the following commands:

# truncate -s 80G /mnt/file# time rm /mnt/file

In detail, the performance of this filesystem without this commit is poor, totalling about 4 minutes and 46 seconds in real time, with 12 seconds of system time. In contrast to the patched kernel, it totals about 1 second in real time, with 17 milliseconds of system time.

It’s a huge improvement!

In honor of Trans Day of Visibility, here’s something really cool for you to know…

A computer scientist trans woman by the name of Sophie Mary Wilson was a co-creator of the ARM architecture.
