In the afternoon I finished Dune
Messiah. I liked
the book a lot, highly recommended.
Children of Dune
The sand-blasted world of Arrakis has become green, watered, and
fertile. Old Paul Atreides, who led the desert Fremen to political
and religious domination of the galaxy, is gone. But for the
children of Dune, the very blossoming of their land contains the
seeds of its own destruction. The altered climate is destroying the
giant sandworms, and this in turn is disastrous for the planet's
economy. Leto and Ghanima, Paul Atreides's twin children and his
heirs, can see possible solutions - but fanatics begin to challenge
the rule of the all-powerful Atreides empire, and more than economic
In the early evening I started in the third book of the Dune
Chronicles by Frank Herbert: Children of Dune.
I recently went through the exercise of testing
jc on several traditional
and next-gen shells to
the integrations. jc is a utility that converts the output of many
commands and file-types to JSON for easier parsing in scripts. I
have typically highlighted the use of JSON with Bash in concert
but this is 2022 and there are so many more shells to choose from!
In this blog post, I will provide my view on Nix and Docker -- I
will elaborate about some of their key concepts, explain in what
ways they are different and similar, and I will show some use-cases
in which both solutions can be combined to achieve interesting
Since I was unable to travel for a couple of years during the
pandemic, I decided to take my new-found time and really lean into
Rust. After writing over 100k lines of Rust code, I think I am
starting to get a feel for the language and like every cranky
engineer I have developed opinions and because this is the Internet
I’m going to share them.
In the early evening I noticed that Adam's female Brazilian whiteknee
tarantula, scientific name Acanthoscurria geniculata, had
molted. Because I don't check daily it might have happened earlier
this week but the tarantula looks really fresh so it might have
In the above photo you can see the spider in the bottom right corner
and her exuviae, the cast-off exoskeleton, in the top left corner. The
tarantula is resting on the web mat she made to molt on top of.
I wanted to grab a CSV version of a JSON representation of an
entityset in the Northwind OData service. Here's how I converted the
JSON structure into CSV with jq, and along the way, I talk about
arrays, objects, iterators, object indices, variables, identity,
array construction and format strings.
With each major Python release, all the attention goes to the new
language features: the walrus operator, dictionary merging, pattern
matching. There is also a lot of writing about asyncio and
typing modules — they are developing rapidly and are obviously
important for the core team.
The rest of the standard library modules receive undeservedly little
attention. I want to fix this and tell you about the novelties
introduced in versions 3.8–3.10.
In this post, I will show you how to use cryptobyte to parse a TLS
Client Hello message, and introduce
https://tlshello.agwa.name, an HTTP
server that returns a JSON representation of the Client Hello
message sent by your client.
Monads hide some of the repeated logic of composing functions with
embellished types, so that you don’t have to feel like Bart Simpson
in detention, but rather like Bart Simpson on his skateboard,
bowling a cricket ball, while it is his turn to bat.
Just like UIKit, SwiftUI is implemented on top of an event loop that
dispatches messages to your UI code. The UI code in turn may trigger
parts of the screen to be re-rendered. The handling of messages and
rendering of graphics on screen form the render loop of an
application. All UI frameworks are based on a render loop, in
SwiftUI it is hidden particularly well. Most of the time, it works
under the hood without us needing to know anything about it. It is
amazing how we can write UI code without even needing to understand
what an event loop is, and without us needing to worry about how
often to render screen content. But in some cases, it is useful to
know what is happening behind the scenes.
We've now tested every version of Apple's M1 processor, from the
first M1 chip in the 13-inch Macbook Pro all the way up to the M1
Ultra in the new Mac Studio, and the chip's ability to scale
performance is pretty incredible. The M1 Ultra fuses two M1 Max
chips together to get you a processor with 20 CPU cores and 64 GPU
cores, along with up to 128GB of RAM, and it's one of the fastest
processors we've ever tested.
This astonishes youngsters, when they enrolled first time to school
or kindergarten. They found coincidences when list their
birthdays. Only 23 random persons in groups is enough to have a
probability of 50% that there is a pair with the same birthday.
