Is it just me or is the merge style used for the repo very difficult to follow? Am I holding it wrong?

Were you around before the new installer came out? It was light speed compared to what was before!

Wouldn’t any decent bike-riding pelican have a bike tailored to pelicans and their wings?

Seems like a similar but less elegant solution as parsing and normalization to a “safe” subset but not just blasting it to pixels.

There is already code to support phone/tablets in asahi/m1n1 bootloader (for use with an exploited bootrom).

It is clear from the quality that all vendors of EDA software actively hate their paying customers.

Just wonder - why are EDA tools just now starting to get HiDPI support? I’m pretty sure Altera, Xilinx/AMD, etc haven’t bought HiDPI monitors for their own developers!

There are certainly people removing high-end FPGAs from surplus/scrap commercial products and reselling them.

The top-level Verilog module and Vivado .xdc file (contains pin mappings, timing constraints, etc) from Gidel for the HawkEye 20G-48. [0] No SDK from Gidel though.

My back burner project for them is to create a PCIe TLP sniffer/MiTM/device emulator by hooking up two together via 10 GbE for relaying TLPs with one of the remaining 10 GbE connection going to a host PC for the sniffed/injected TLPs. The Aria 10 FPGA PCIe hard IP allows for either root or endpoint mode so I “just” need to draw the rest of the owl, avoiding any Quartus IP modules that would make the setup non-transparent.

I’m not sure what using a 10 Gbit link for PCIe will be like with faster devices but fail0verflow got away with TLP proxying with 115200 baud UART. [1]

Vivado, along with expensive adaptors, supports some JTAG dongles that are just FT2232 with an EEPROM that contains USB descriptors that Vivado recognizes and treats as a (some low cost onboard adaptor for Digilent boards, IIRC) supported adapter. https://gist.github.com/rikka0w0/24b58b54473227502fa0334bbe7...

If you like FT2232, you’ll love the Tigard board that takes a FT2232H and adds level shifters and is basically as tricked out as you can make a FTDI adapter. https://github.com/tigard-tools/tigard

https://github.com/ReverseApple/dgraph but IIRC it still has some @rpath and its Apple extended family counterpart issues. PRs welcome!

The latest Apple TV SoC (released in late 2021) is the same one used in the iPhone 13 and 14 (non-Pro). 2x 3+ GHz P-cores and 4x E-cores and 4GB of memory. I haven’t noticed any issues.

There is some enum or #define in a header I found recently that suggested there was once QAT acceleration of something XML related! I can’t find any documentation about it though.

They better keep the new linker open source like they did for ld64 (despite delays), or it is going to become a private ABI nightmare.

New comment by jevinskie in "I Tried Ketamine to Treat My Depression. It Was Terrifying"

jevinskie — Sun, 12 Feb 2023 16:42:22 +0000

I was making great progress with Spravato (eskatamine nasal spray) from April until the end of July. I then moved from California to Indiana and it took over a month and a half to find someone who could provide treatment (terrible mental health care in the state). Unfortunately I have never been able to reach a disassociative state since then and even spacing the treatments three weeks apart I haven’t been able to feel much effect at all anymore.

Does tolerance build up that quickly? It doesn’t help that Jansen and insurance won’t cover any more than 3x doses (I take them in one visit) a week.

I’ve thought about IV infusion which could give a higher dose but those treatments are also hard to find in Indiana and aren’t covered by insurance (about $1000 a treatment).

Two weeks ago I tried 1/4 oz of shrooms and 5 days later 800 ug of LSD. Besides the body load, the shrooms made me a bit giddy with slightly enhanced colors while the LSD only produced a few visual patterns. Clearly something wasn’t right if those doses weren’t sending me into space like they did 5+ years ago the last time I was using psychedelics.

I discontinued my medications, including Vraylar and Wellbutrin since they seem to have saturated my neuroreceptors or something. Since then I am feeling 100% better (going from 5-15/100 of my original mental health state to about 40-50/100 compared to pre-depression). I’m hoping with more weeks off of my previous medications, they might again have an effect but I’m wondering what other people’s experiences have been.

The touchbar on Intel machines ran bridgeOS. On ARM machines there is no separate SoC and the touchbar is controlled by the main SoC.
