Welcome to the second part of this series aimed to make you a better
Vim user! If you have no idea about Vim, you should begin with the
first part. In this
article, I’ll explain many more concepts, some of them making Vim
truly special compared to other editors. Who wasn’t blown away
discovering Vim’s macros?
Specifically, we’ll see together:
Ways you can organize open files in Vim using buffers, windows,
tabs, and the argument list.
Useful motions to jump quickly from one place to another in your
Mapping new keystrokes to old keystrokes or commands.
Powerful functionalities to repeat some of your keystrokes.
Ways of manipulating the command line history.
Plugins which offers different ways to manage some ideas we saw
The essay assumes you understand Git well enough to use it to
version control your projects. It focuses on the graph structure
that underpins Git and the way the properties of this graph dictate
Git’s behavior. Looking at fundamentals, you build your mental model
on the truth rather than on hypotheses constructed from evidence
gathered while experimenting with the API. This truer model gives
you a better understanding of what Git has done, what it is doing,
and what it will do.
Latin expressions are often adopted into English, often with an
extended or figurative meaning. Here are fifty of the most common
phrases, followed by their literal translation in Latin and the
meaning in English (omitted when the meaning follows the literal
In the afternoon I bought the Minecraft Java
as a small Christmas present for our children. I was expecting to be
able to install it in my account on the Mac mini and each child be
able to run his/her own version. But alas, after I had installed it
and we switched to Adam's account starting Minecraft resulted in a
small window stating that the Minecraft Launcher was unable to start
Installing Minecraft using my Microsoft account in Adam's session
worked, though. So after about an hour of installing, updating,
etc. he was finally able to play Minecraft.
I will look further into this issue later.
The Christmas Chronicles: Part Two (2020)
Kate Pierce, now a cynical teen, is unexpectedly reunited with Santa
Claus when a mysterious troublemaker threatens to cancel Christmas -
At my mother's we watched The Christmas Chronicles: Part
Two. Although I didn't watch
the entire movie, busy with making coffee and a desert, I liked it
more than the first one. I give it a 7 out of 10.
Linux Hardening Guide
Linux is not a secure operating
there are steps you can take to improve it. This guide aims to
explain how to harden Linux as much as possible for security and
privacy. This guide attempts to be distribution-agnostic and is not
tied to any specific one.
A perceptual color space is desirable when doing many kinds of image
processing. It is useful for things like:
Turning an image grayscale, while keeping the perceived lightness
Increasing the saturation of colors, while maintaining perceived
hue and lightness
Creating smooth and uniform looking transitions between colors
Unfortunately, as far as I am aware, while there are color spaces
that aim to be perceptually uniform, none are without significant
drawbacks when used for image processing.
For this reason I have designed a new perceptual color space,
designed to be simple to use, while doing a good job at predicting
perceived lightness, chroma and hue. It is called the Oklab color
space, because it is an OK Lab color space.
How to Favicon in 2021: Six files that fit most needs
It is time to rethink how we cook a set of favicons for modern
browsers and stop the icon generator madness. Currently, frontend
developers have to deal with 20+ static PNG files just to display a
tiny website logo in a browser tab or on a touchscreen. Read on to
see how to take a smarter approach and adopt a minimal set of icons
that fits most modern needs.
Build a Tiny Certificate Authority For Your Homelab
In this tutorial, we’re going to build a tiny, standalone, online
Certificate Authority (CA) that will mint TLS certificates and is
secured with a YubiKey. It will be an internal ACME server on our
local network (ACME is the same protocol used by Let’s
Encrypt). The YubiKey will securely store
the CA private keys and sign certificates, acting as a cheap
alternative to a Hardware Security Module (HSM). We’ll also use an
open-source True Random Number Generator, called Infinite Noise
spice up the Linux entropy pool.
We rendered the top 1 million pages on
the web, tracking every conceivable performance metric, logging
every error, noting every requested URL. To our knowledge, this
produces the first dataset that connects performance, errors, and
library use on the web. In this article, we analyze what the data
can tell us about creating high performance web sites.
If I am to start working on a new project today, I would hesitate to
attempt it in a language that does not have compile-time type
checking. However, I do have to deal with Python at work (though we
are slowly phasing it out). Also, I have been working off and on, in
my spare time, on a Python project that has over the past 3+ years
gotten fairly large as personal projects go. It started out as a
one-off quick script. It eventually evolved into something larger
that actually does something useful for me so I ended up adding to
it and maintaining it.
Somewhere over a year and a half back, after being frustrated with
my inability to refactor this code like I can with other type safe
languages, I started exploring the possibility of adding type hints
to the codebase. Now, after having spent the requisite time to
understand the implications of type hinting, and whether it’s
useful, and to be able to show this as a consolidation of my
thoughts on the matter to friends and colleagues, I decided to write
this post on what an absolute joy it has become to refactor and
work with Python once you have type checking enforced.
To understand what makes it so special, the first half of this post
explains how a digital camera develops a photo. Then we go on to
explain the strengths and weaknesses of traditional RAWs. Finally,
we dive into what’s unique about ProRAW, how it changes the game,
and its few remaining drawbacks.
In this article, I want to cover three things you can do with
proxies that will enhance your objects specifically. Hopefully, by
the end of it, you’ll be able to expand my code and maybe apply it
yourself to your own needs!
Haskell has a stigma of having poor or no documentation at
all. Though more and more maintainers are doing a hell of a job to
improve the quality of their libraries and applications, it is still
not enough. We need to strengthen our vision of documentation
collectively and as a consequence, master the existing tools for
The blog post is going to give Haddock overview, suggest
documentation best practices, reveal the specialities of the Haddock
tool, and show-and-tell lots of different examples of how to squeeze
more out of your documentation. It should be interesting to library
maintainers, developers who want to improve their documenting skills
and everyone interested in documentation techniques in Haskell.
