Hey, anyone out there sysadmin'ing #Solaris? The Shadow Brokers dump of NSA exploits includes a working remote root exploit for Solaris 6-10 x86/Sparc (and potentially v11). It attacks RPC services to spawn a remote root shell.

Following Sunday's adventures playing with PAL and NTSC timing in the #PSX, and preparing timer emulation code for that, I went to bed and dreamed a stressful nightmare in which I was back in college and had an exam on a video standard I had not studied at all.

Software engineering - it's not good for you, clearly.

Sony's #PSX hardware is so wonderfully weird, it's a joy to explore. When the code cache is disabled, reading from certain unused IO registers (such as one of the unused timer control registers) will return the opcode of the next instruction the MIPS CPU core will execute :joy: #playstation

Any love on Mastodon for #RustLang? Tonight, cracking on with a simple MIPS #PSX emu written in #Rust. I know there's another (unfinished) Rusty #PlayStation emu out there - my one started out as a MIPS CPU emulator that got out of hand. I also want to get sound + GPU working so I can play the iconic PS1 boot intro in full.

Here's the serial debug output when it starts up... https://mastodon.cloud/media/UpKBBJt_JDCop8f3fxA

The number of Mastodon instances is still growing. Ours (mastodon.cloud) is the 2nd largest after the 1st / primary one https://instances.mastodon.xyz/

Whoops - Ubuntu's giving up on Unity and switching to GNOME as the default desktop UI! Also: bye bye Ubuntu phones and tablets. https://web-beta.archive.org/web/20170405184538/http://insights.ubuntu.com/2017/04/05/growing-ubuntu-for-cloud-and-iot-rather-than-phone-and-convergence

There's more info + analysis of Google's AI processor chip, the TPU, here :) https://www.nextplatform.com/2017/04/05/first-depth-look-googles-tpu-architecture/

A good peek inside Google's powerful and heavily customized AI calculator chip - it's called the TPU and it's a PCIe-connected ASIC akin to an FPU. The design was led by top MIPS CPU architect Norman Jouppi.
