The OpenBIOS Project is an open source implementation of OpenFirmware, a Firmware based on Forth (used in SUN and PPC Apple computer, among others)

It can also be used as a hosted Forth running on top of a normal operating system.

OpenBIOS is used for booting Solaris and MacOS X PPC in QEMU.

Debian 10 buster has been released! https://bits.debian.org/2019/07/buster-released.html

While arguing about the feasibility of reverse engineering Windows into ReactOS, I just remembered that the Windows kernel comes with an x86 emulator to run VGABIOS in.

The amount of weird shit that comes with Windows for reasons is astounding.

GnuPG — "SKS Keyserver Network Under Attack":

https://gist.github.com/rjhansen/67ab921ffb4084c865b3618d6955275f

"If you fetch a poisoned certificate from the keyserver network, you will break your GnuPG installation."

"High-risk users should stop using the keyserver network immediately."

Received my Joulescope today! It will be a great addition to my toolset. Can't wait to power optimize all the things now. I am impressed how much stuff is on the board to do the job. I wish the schematic was published so I could learn in more detail about how it works.

The reset process for GE smartbulbs is the sweet spot between "impossible to do intentionally" and "easily done by a toddler playing with the lightswitch."

Did you hear? There's a fan project to build Half Life 2 Episode 3. It's coming along rather nicely, and apparently it will support Linux.

Wow, this little logic analyzer for 10 bucks (and @sigrok) make suuuuch a difference working with hardware, it's unbelievable. With all the debugging options I have now, I might just be able to get the original design with the PIC working...

In reality, worf just wanted a vacation and his next leave was too far off

So the verdict is in, the coffee warmer is a great tool! It really makes rework easier! And it fits under my microscope unlike the bigger hot plate. It also seems to be ok with some hot air action too! :D

#libsigrok now supports the Sysclk SLA5032 32ch/500MHz logic analyzer. #sigrok

The Glasgow digital interface explorer revC1 prototype boards arrived! I will change Hana drawing to be only outlines so she also looks good on a white background PCB in the next update. Yes they did arrive a little while back but I did not have the spare time to work on them.

*sigh* "As an example, in our paper we demonstrate an attack against OpenSSH in which we use RAMBleed to leak a 2048 bit RSA key. However, RAMBleed can be used for reading other data as well." https://rambleed.com
