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

picking a hostname is the hardest problem in computer science
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.

I am not reading comments on Hacker News because I pretty much remember all the various sentiments from my first "Show HN", and I do not have the energy to also answer questions there
But as others have pointed out, these are all nice problems to have. I am so happy that people are finally using my work at large. <3

The most important thing mastodon users need to realize is that you don't need to be on mastodon.social to be part of the network. Mastodon is just one server in the larger federation.
I know what Mastodon users are all thinking...

When recommending to your friends, give the other instances some love too: https://instances.mastodon.xyz/ It looks like mastodon.social is under even heavier load than yesterday right now

I absolutely love that InfoSec has moved en masse over to Mastodon. Makes this place a lot more interesting.
What does it take to run a Mastodon instance? See live geeky system stats here for mastadon.cloud - which has 821 users... https://mastodon.cloud/netdata/
Currently cruising at 248kbps inbound, 9091kbps outbound, 52.1% CPU utilization, 76.5% RAM in use.
