Aneng AN8009 DMM with Hacks

Aneng AN8009 DMM

I just picked up an Aneng AN8009 DMM as an upgrade to the cheap, cheap (but surprisingly OK) Circuit Specialists branded MY-68 I’ve had as my my home on-desk approxometer for ages. It’s a nice meter for $30ish, and can be readily hacked to improve its performance. I tend to point people to mid-range Uni-T DMMs when they asked for decent hobby meters, but now I might switch to one of these plus one of those little $10 Atmega328 based component testers cloned everywhere for ~$10 as basic electronics lab instruments.

One of the dumbest things I’ve ever published

Source: Hacker News

Article note: This is an excellent "I was wrong" piece about data collection vs. privacy protection. I'd like it if the stance were a little more "Because the collected data will not be used to optimize for things that benefit anyone other than parasites."

Google relents slightly on blocking ad-blockers – for paid-up enterprise Chrome users, everyone else not so much

Source: The Register

Article note: Feeling good that I already switched [back] to Firefox. Chrom[e|ium] has a slightly more capable engine, but the inability to run extensions on mobile, chatter about reducing content blocking extension power on desktop, and IE-in-the-early-2000s idiosyncratic behavior and market penetration have made its trajectory as a coercive problem clear.

Freeloaders will be limited to less capable content filtering

Google Chrome users will continue to have access to the full content blocking power of the webRequest API in their browser extensions, but only if they're paying enterprise customers.…

AMD Ryzen 3000 Announced: Five CPUs, 12 Cores for $499, Up to 4.6 GHz, PCIe 4.0, Coming 7/7

Source: AnandTech Articles

Article note: Those are attractive parts. I'm surprised and slightly disappointed there isn't an integrated graphics part announced in the initial lineup, but the mid-range parts (especially the 3700X) are very appealing.

Today at Computex, AMD CEO Dr. Lisa Su is announcing the raft of processors it will be launching on its new Zen 2 chiplet-based microarchitecture. Among other things, AMD is unveiling its new Ryzen 9 product tier, which it is using for its 12-core Ryzen 9 3900X processor, and which runs at 4.6 GHz boost. All of the five processors will be PCIe 4.0 enabled, and while they are being accompanied by the new X570 chipset launch, they still use the same AM4 socket, meaning some AMD 300 and 400-series motherboards can still be used. We have all the details inside.

A Bit of 3D Printer Maintenance

We were doing a bit of beginning-of-summer lab maintenance and one of the projects was to figure out why the MakerGear M2 (Which has been heavily modified over the years, Azteeg x5 mini motherboard, E3D hotend, etc.) was behaving so strangely.
Well… there’s your problem.
Fresh 0.35mm nozzle next to the bored out, abraded down corpse of a nozzle that we’ve, in retrospect, been running for something like 3 years. Turns out printers work much better when the nozzle aperture is roughly the size it’s supposed to be.
Still seeing some odd temperature fluctuation, but … look at that thing.

New Assange indictment adds 17 espionage charges

Article note: Assange is a shitweasel, as people who discover their unjust victimization in one aspect allows them to get away with all kinds of bad behavior tend to be, but this shit sticking would be _real bad_ for the free press.

Today, the Department of Justice filed a new indictment of WikiLeaks founder Julian Assange with the US District Court in Alexandria, Virginia—adding 17 more charges atop the original hacking charge used to file for Assange's extradition from the United Kingdom. The new charges are all espionage-focused: conspiracy to receive, obtaining, and disclosure of "national defense information. Each of the 17 counts carries a potential prison sentence of up to 10 years.

In a statement announcing the filing, a Justice Department spokesperson said, "The superseding indictment alleges that Assange was complicit with Chelsea Manning, a former intelligence analyst in the US Army, in unlawfully obtaining and disclosing classified documents related to the national defense." The new counts allege, among other things, that Assange conspired with Manning to steal "national defense information," obtained that information from Manning, and "aided and abetted her in obtaining classified information with reason to believe that the information was to be used to the injury of the United States or the advantage of a foreign nation."

In a Twitter post, a WikiLeaks spokesperson wrote, "This is madness. It is the end of national security journalism and the First Amendment."

Android at I/O 2019: The Project Mainline update system and other highlights

Article note: From the platform who lemming-removed "Tactile" and "Consistent" from interfaces comes "our competitor removed Discoverability, so we feel compelled to do the same."

Google I/O 2019 wrapped up on May 9th, but we're still picking through the incredible flood of information that came out of the show. In addition to the slew of announcements on keynote day, there are dozens of hours of sessions and documentation, plus a whole new Android release to pick though. Here are a few highlights from the show.

Android’s gesture navigation is actually good now

Every Google I/O presents a new release of Android, and paired with Google I/O 2019 is Android Q Beta 3. There really aren't a ton of changes in this beta release, but there is a new navigation system. There are three versions of system navigation in Android Q Beta 3, actually. The traditional three-button navigation is an option, even on devices like the Pixel 3, which originally did not ship with it. Apparently, the three-button mode will be returning to all phones for accessibility considerations, since the gesture system requires a significant amount of fine motor control. The existing Android Pie gesture system has been renamed "two-button navigation." The third option, called "Fully gestural navigation, "is new for Android Q Beta 3, and it's the best version of Android gesture navigation yet.

In Android P, the "two-button" gesture navigation was a bit of a mess. Google only replaced the Recent Apps button with a gesture, and Home and Back were still buttons. The bar didn't save any space, so there wasn't a huge benefit to using it. Beta three solves a lot of these problems. Every button is now a gesture. The navigation bar has been minimized to a slim strip about a third of the height of the usual bar. Some apps will even give you a fully transparent gesture navigation area. The new setup is very reminiscent of iOS, and that's what everyone has been asking for since the launch of gesture navigation with Android P.
