This may be the most English thing I have ever seen.
Messing around (ab)using ESP32 capacitive touch sensors for non-contact water level measurement. Can tell when the water level is over an electrode.
(After all these sensors are intended for measuring when bags of mostly salt water poke them...)
Refurb & upgrade of my electronics bench is going alright
(Pink is primer, although makes me wish I'd picked a more interesting colour for topcoat...)
My new "USB cable drawer" is working out great
Seen a lot of Bad Takes about the fatal Uber accident in Arizona. This (IMO) is a good writeup based on public info to date http://ideas.4brad.com/it-certainly-looks-bad-uber

An earlier prototype has much the same chips, but no big ARM logo.
I think VLSI were the first ARM licensee - there could be an ARM in there, and given the label, I think there must be. Perhaps needed to setup the board for the PPC to boot.
From Twitter comes a few clues:
Apple not the designer for these, Daystar.
A "real" PowerMac 6100 of the same era has no VLSI chips at all. https://images.esellerpro.com/2131/I/542/07/POWERMAC6100%20001.jpg …
Similar era 68K Macs have lots of VLSI chips but nothing marked ARM.
Any vintage Apple buffs that can explain the ARM logo on this Macintosh Processor Upgrade Card (PowerPC 601 PowerMac, circa 1994)? I know Apple & VLSI were seed investors in ARM. Do old PowerPC chipsets have an embedded management core? https://mastodon.social/media/6DXjn70Niv-zKOw1JRQ

An "NSA backdoor" proposed TLS extension finally turns up inthe wild: in random Canon printers that fail to work with TLS 1.3...
As the blog post points out at length, gee this spy stuff can be super mundane.
Rant about browsers Show more
I know everyone's ready to rake Mozilla over the coals for that Mr Robot stunt, but keep in mind that they build their own browser engine, which is very expensive: http://robert.ocallahan.org/2017/12/maintaining-independent-browser-is.html
So you can switch to qutebrowser/WaterFox/etc., but keep in mind that they're just downstream from the people who actually build the browser engine. Mozilla is fighting on a totally different level than those other browsers.
