The target audience is people who are familiar with Urbit's architecture, though not necessarily much of its code.

Plunder and Urbit

As some of you already know, i recently left my job as a core dev for the Urbit Foundation to work on a similar system called Plunder. Plunder was created in 2020 by two former Tlon employees, after their proposal for a new version of Nock was rejected. They have since reworked that significantly and built a reference implementation of their own system. You can follow its continued development on its mailing list.

I've known about Plunder for quite some time now, but their recently released demo -- in which the system is used to serve a 70 GB dataset, complete with metadata and searchable -- made me feel the need to explore it again and in greater detail. Doing this with my personal server doesn't feel like a big ask, but there is currentl

Windows XP/2003 Product Keys

DEPRECATION NOTICE

Consider this gist to be deprecated. It's full of information that may or may not be correct, given recent findings. Consider the in-development PIDDatabase, and UMSKT, instead: https://umskt.github.io/PIDDatabase-viewer https://github.com/UMSKT/UMSKT

Windows XP/2003 Product Keys

These keys have been tested to work. These are a combination of keys from Chinese websites, trial keys inside ISO's, auto-activate keys in OEM ISO's, and directly from Microsoft's website, all aggregated for your convenience.

Usage

In order to use these keys, you need the right edition of Windows XP/2003. Not just Home/Pro/Enteprise/etc, whether it's a Retail, OEM or Volume version. There's a clear cut way to check this.

Installing Windows and Linux into the same partition

Installing Windows and Linux into the same partition

But WHY?

There was a reddit post about installing Arch on NTFS3 partition. Since Windows and Linux doesn't have directories with same names under the /(C:\), I thought it's possible, and turned out it was actually possible.
If you are not familiar to Linux, for example you've searched on Google "how to dualboot Linux and Windos" or brbrbr... you mustn't try this. This is not practical.

Pre-requirements

  • UEFI system
  • Any Linux live-boot CD/DVD/USB... with Linux kernel newer than 5.15
  • Windows installer USB

How to use a Raspberry Pi to provide WiFi for Ethernet-only devices, and how to use stunnel as a SOCKS server ro provide indirect TLS support

What's this?

I love MSX computers. I have developed quite a few things for them, including a TCP/IP stack and some networking applications. Some other MSX nerds have developed networking hardware, so boom! Here it is, Internet access from MSX, a 1980s 8 bit machine. How cool is that?

However there are a few issues that prevent us the MSX users to reach the absolute networking happiness:

  1. At the time of this writing, there isn't any solution for wireless Internet for MSX, only Ethernet hardware.
  2. InterNestor Lite, the TCP/IP stack for MSX, doesn't support TLS. It's not that the developer (me!) is too lazy to implement it, it's just that a Z80 can't handle the required encryption algorythms. Trust me, I tried.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
