John Gartner is a psychologist who, as founder of Duty To Warn, has raised the alarm about Trump's declining mental fitness. This week, we had the honor of interviewing him for a disturbing conversation about why he’s more worried than ever that the media and the public are missing all the blaring red signs that Trump is slipping rapidly into dementia. https://thinkbigpicture.substack.com/p/john-gartner-trump-cognitive-decline

Found a solution for General MIDI: I forgot that I had upgrade my KORG Classic Collection and it has VST version of Triton, which has a bank for this. KORG's plugins are overally so much better and more stable than what Roland offers and no cloud crap required. They are actually the best software versions of their gear, which is how it should be. With e.g. TB-303 emulation you are better off with D16's Phoscyon2 or perhaps Arturia's ACID-V (have not tested the latter).

Edit: there are suggestions out there that this story is not actually true. So sad, who ever heard of something not being true on the Internet? But does anybody doubt that something like this *will* be true in the near future?

I'm not expert with #JTAG probes so no understanding how compatible probes from different vendors are with each other.

I've mostly used #Lauterbach probes in the past but not very often.

So anyway, I grabbed the info from Internet that with #VisionFive2 SBC Segger J-link family of probes are known to work. Are they my only choice or is there some good and perhaps cheaper but compatible options?

I wonder if anyone has made something to enable playing General #MIDI playback in #Bitwig? Like for e.g. game soundtrack type of stuff.

In #FLStudio there is a General MIDI soundset for #FLEX, which is sort of like a built-in rompler in that DAW. If you import a MIDI file let's say game music from 90s Sierra or Lucas Arts game FL will automatically use this soundset and pick the correct instruments.

Thought that FL part is worth of mentioning because it is not that common knowledge, e.g. I found it by accident :-) What happens in Bitwig is that you get the stock Organ instrument to every channel.

Sound Canvas SC-88 is the only plugin I've ever picked from #Roland it is total garbage. I've never got it run on any machine that I've owned (have had it for 1.5 years, and have occasionally tried it). Also the only plugin I've ever grabbed from Roland (unsurprisingly).

Nice #article about nuts and bolts of #VisionFive2: https://sizeof.cat/post/starfive-visionfive-2/

I found this when searching for information on what pins I should use to enable #JTAG, which I think I can eventually sort out with some info from this article :-)

"'[…]this whole "nested LSM" stuff as a design goal just needs to be all rolled back, and the new design target is "one LSM, enabled statically at build time, without the need for indirect calls."

Because we're now in the situation where the security hooks are actually a source of not just horrible performance issues, but also actual insecurity[…]"'

Mitigations for the "native BHI(Branch History Injection)"[1] hardware vulnerability have just been merged into mainline: https://git.kernel.org/torvalds/c/2bb69f5fc72183e1c62547d900f560d0e9334925

"'BHI attacks may allow a malicious application to influence indirect branch prediction in kernel by poisoning the branch history. […]"

I hate soldering but still would be sometimes nice to have a soldering station at home. What would be a good choice in let's say in less than 500 euros price range? Should also do desoldering (that is my most common use case: desolder old part and solder new part).

Do not need anything too high end, as long as the durability and overall quality are acceptable...

#storj way of billing cloud works for me as my main archive is in local NAS and the amount of stuff in the cloud storage is variable. The first cost me $1.50. also support for S3 API is great thing and makes moving files between cloud, NAS etc. a breeze, when using something like rclone. Totally made sense to migrate from Dropbox...

A Finnish court has decided to let alleged mass extortionist Julius "Zeekill" Kivimaki free pending the rest of his trial, without even an ankle bracelet. This is a guy who was hiding in France under an assumed name and passport when police arrested him and sent him back to Finland to face charges that he extorted thousands of patients of the Vastaamo psych practice in 2020.

https://www.hs.fi/kotimaa/art-2000010206299.html

"The processing of the data breach and blackmail case is scheduled to continue on Wednesday at 9 o'clock.

"The trial will continue, even if he doesn't show up," Vainio formulates Kivimäki's arrival for the upcoming hearings."

They've taken away his passport, but it's not hard to walk out of Finland. Hope they're following him around wherever he goes.

Overall I think VisionFive2 is overall better board than e.g. BeagleV for kernel development tasks because:

  • 2/3 of price
  • twice more memory at least in the 8GB version
  • Hat that can supply power and UART through micro-USB is about half price of comparable mikrobus and the overall setup is more compact in price.

I had no idea how the CPU’s compare but for my tasks I neither care :-) I guess they help each other to mature in Linux kernel because the hardware platform are from the same family (jh7100 for beaglev and jh7110 for visionfive2). For some other task, e.g. building something around the SBC, the evalution might different.

I came to these conclusions based on working with VisionFive2 and I do not have BeagleV at my hands so that my cause some dilation but at least this board feels like better bang for the buck.

Still would love to get my hands on BeagleV too and get more familiar with it, and yeah, competition is a great thing, and can’t wait for more Beagleboard RISC-V products.

No more fighting with a loose TTL-USB-cables: I have USB hub shield with USB-to-UART port :-) Or two of these: one for Raspberry Pi 3B+ and other for VisionFive 2 RISC-V SBC (in the pic). Need to still pile a TPM2 chip to the pins on top of the shield and hopefully it will still work. #arm #riscv #visionfive2 #raspberrypi

I quite often have to use IP for keyserver in #GnuPG's #macOS version. It does not otherwise find the route to the host. Never happens in any other platform...
