Generally the Ethereum (Web3) keystore file is a kind of container for the private key, it has the specific structure mostly related to encryption details. Actually you will not find the private key there as a plain text, but the keystore file has everything to decrypt the private key… with some tricks surely. When youContinue reading “Day 18 – Dissecting the Go-Ethereum keystore files using Raku tools”

Day 17 – Writing some horrible Raku code this Christmas!
Santa only had a few days left to make sure everything was ready to go, but with all the stress of the season, he needed a break to recharge. He grabbed some cocoa and hid away in a nook to relax his body and distract his mind, tuning into one of his favorite Youtubers, Matt Parker.Continue reading “Day 17 – Writing some horrible Raku code this Christmas!”
Day 16 – It’s Too Generic; Please Instantiate!
As the Christmas approaches, the time for unwrapping presents is near. Let’s review a present Rakudo release 2023.12 is going to have for you. Long ago I once got a question related to type capturing. Don’t remember the question itself, but remember the answer Jonathan Worthington gave to it (rephrasing up to what my memory managed to keep): “YouContinue reading “Day 16 – It’s Too Generic; Please Instantiate!”
Day 15 – An Object Lesson for the Elven
This post is a continuation of Day 5 – The Elves go back to Grammar School, you may recall that our elfin friends had worked out how to parse all the addresses from the many, many children who had emailed in their wish lists. Now, as they sing along to “Christmas is Coming”, they realiseContinue reading “Day 15 – An Object Lesson for the Elven”
Day 14 – The Magic Of Q (Part 2)
A few days after having done The Magic Of Q presentation, Lizzybel was walking through the corridors of North Pole Grand Central and ran into some of elves that had attended that presentation. When will you do the final part of your presentation? one of them asked. We could do it now if you want,Continue reading “Day 14 – The Magic Of Q (Part 2)”
Day 13 – Networks Roasting on an Open Fire, Part 3: Feeling Warm and Looking Cool
by Geoffrey Broadwell In parts 1 and 2 of these blog posts, I roughed out a simple ping chart program and then began to refactor and add features to improve the overall experience. It’s functional, but there’s a lot to improve upon — it doesn’t use the screen real estate particularly well, there are someContinue reading “Day 13 – Networks Roasting on an Open Fire, Part 3: Feeling Warm and Looking Cool”
Day 12 – Perspectives on RakuDoc Version 2
Just in time for Christmas This project started with the modest aim of documenting parts of Rakudoc V1 (what used to be called POD6 that had been specified, but not included in the original documentation. Except … some parts of the specification had not been implemented in the Pod::To::HTML renderer. And some parts were outdated. So aContinue reading “Day 12 – Perspectives on RakuDoc Version 2”
Day 11 – Networks Roasting on an Open Fire, Part 2: Axes to Grind
by Geoffrey Broadwell In part 1 of these blog posts, I roughed out a simple ping chart program that produced output like this as it ran: This is over-minimalist; a user couldn’t even tell the scale of the latency measurements. It’s not at all obvious whether this is a fast or slow connection, and whetherContinue reading “Day 11 – Networks Roasting on an Open Fire, Part 2: Axes to Grind”
Day 10 – The Magic Of Q
Santa continued their dabbling in the Raku Programming Language, but got confused by single quotes, double quotes, and all the things that start with q/. So they decided to have Lizzybel do an exposé about the mechanisms behind quoting. But I already did that 9 years ago! Lizzybel exclaimed! Well, I certainly don’t remember that,Continue reading “Day 10 – The Magic Of Q”
Day 9 – Networks Roasting on an Open Fire, Part 1: Whipuptitude
by Geoffrey Broadwell My home Internet connection is less than ideal. On the good days it’s fine I suppose, but on the bad days — and there are a lot of them — well, my ISP seems to be doing its darnedest to be earning coal in its collective stockings. Meanwhile I hear shouts across theContinue reading “Day 9 – Networks Roasting on an Open Fire, Part 1: Whipuptitude”
