Although Microsoft no longer supports Windows XP updates, I'm sure many users still use it due to personal habits or job demands. Therefore, XP's product keys may still be necessary. Here lies the most comprehensive list of Windows XP product keys.

The following CD keys are official and original from Microsoft, primarily used for Windows XP Professional Service Pack 2/3 VOL/VLK system images, which are among the easiest to find on the Internet.

Blind Merged Mining with covenants ( sighash_anyprevout / op_ctv )

Update: the content of this gist is also explained in this Spacechains video.

This write-up was also published on bitcoin-dev.

Blind Merged Mining (BMM) is the idea of committing the hash of another blockchain into a unique location on the Bitcoin blockchain, and paying a Bitcoin fee to miners for the privilege of deciding this hash and capturing the fees inside the other blockchain. Since miners don’t have to know what the hash represents and are simply incentivized to choose the highest bidder, it requires no extra validation on their part (“blind”). This idea was originally conceived of by Paul Sztorc, but required a specific soft fork. [0]

In essence, BMM is a mechanism that allows external blockchains (altcoins, tokens) to outsource their mining to the Bitcoin blockchain. Instead of burning electricity with ASICs, th

Introduction

I'm Ruben "Bitcoin Sorcerer" Somsen. I do protocol design in order to enhance Bitcoin - SwiftSync, Silent Payments, Spacechains, Statechains, and more.

I'm co-founder/director of the 2140 Foundation together with Josie. We're a stable and independent European hub for Bitcoin development with a physical office in Amsterdam, focused on increasing developer satisfaction, growth, and productivity.

I moderate the bitcoindev mailing list and am involved with the BIP editor process, Delving Bitcoin, and BitDevs Amsterdam. In the past I've run the Seoul Bitcoin Meetup (2014-2020) and co-hosted the Unhashed Podcast (2018-2022).

Introduction

Boolean() or !! (double bang, double negation)?

What's the best way to answer the question "true or false?" in JavaScript

JavaScript does not bother you too much with types (at first), which is both a blessing and a cure. But we all know the Boolean type. Boolean variables can either be true or false. Yes or no.

Every value in JavaScript can be translated into a boolean, true or false. Values that translate to true are truthy, values that translate to false are falsy. Simple.

This is about two ways to make that translation.

Ford Fusion

Overview and Rationale

Ford Fusion was an overhaul of Urbit's over-the-air upgrade process and a rewrite of its build system. The new update system corrects a few long-standing bugs with the previous one, and the new build system is simpler, smaller (by around 5,000 lines), and easier to manage.

Since deployment of Ford Fusion to the livenet in late June, over-the-air updates (OTAs) have been much smoother. Before Ford Fusion, it was common for an OTA to take several hours, use too much memory, and leave ships in inconsistent states. After Ford Fusion, multiple OTAs have been pushed out, including kernelspace changes, and most users didn't even notice.

Urbit has always been able to update itself OTA, but this process has often been rocky. Updating an operating system kernel on-the-fly is a difficult problem in general, like performing heart replacement surgery on yourself while running a marathon. Code that allows Linux to update its kernel in this way became a startup called Ksplice, won

docker kill $(docker ps -q) to kill all running containers
docker rm $(docker ps -a -q) to delete all stopped containers.
docker volume rm $(docker volume ls -q) to delete all volumes.
docker rmi $(docker images -q) to delete all images.

Run all commands:

docker kill $(docker ps -q) && docker rm $(docker ps -a -q) && docker volume rm $(docker volume ls -q) && docker rmi $(docker images -q)
