For certain types of computation, in particular array-focused code, the Numba library can significantly speed up your code. Sometimes you’ll need to tweak it a bit, sometimes it’ll just work with no changes. And when it works, it’s a very transparent speed fix.
In this article we’ll cover:
Why using NumPy on its own is sometimes not enough.
The basics of using Numba.
How Numba works, at a high-level, and the difference that makes to
how your code runs.
Email was one of the earliest services for communication via the
internet. But, hosting such a simple service is quite complicated
nowadays. In this post I have documented how I set up an email
server for a business quickly and easily.
In this post I will be sharing some tips, which can be used for
better code quality. It will also help you not to shoot yourself in
the foot later in the process.
As many know, Django is an awesome web framework. It allows building
webapps, prototypes etc. blazing fast. I have been using it for most
of my projects, and I have never been disappointed. Django works
great in small to medium codebases. The problems start to arise,
when codebase start to grow to millions of LOC with hundreds of
models.
In the morning we went to Amsterdam. We had planned a visit to the
Anne Frank House in the
afternoon. When we arrived we first got a short introduction and then
could wander through the various room, each with an explanation. The
visit was not easy to me and I kept wondering how people could be this
cruel to others.

Kindergarten class.
After the tour we paid a visit to the bookshop. Adam wanted the Dutch
version of Anne Frank's diary, which we bought. Alice already owned an
English edition which I bought in a second-hand store some time ago.

On the way back Adam read a little in the diary in the train. But he
got tired and gave the book to me and I took the above photo. I am
considering to read the book as well.
Today I will show you how I installed the latest snapshot of OpenBSD
on my Pinebook Pro with plenty of detail so that you can do it,
too. I will include instructions for setting up full disk
encryption, and conclude with a summary of my experience running
OpenBSD on this device.
Welcome to one of the last articles of this
series!
Previously, we
covered how to use external dependencies to lessen the work
necessary to implement our plugin system. Now that we know how to
actually get started, we’ll implement it once and for all.
Like with so many things in programming, there are no right or wrong
answers here, but I hope that this article has shown a few different
ways to combine the functionality of multiple protocols, and what
sort of tradeoffs that each approach comes with.
Out of curiosity, I was trying to understand how PostgreSQL stores
the data onto the disk and there are a few interesting things that I
have noticed that might be useful for application developers. In
this post, I will try to go into the implementation level details
and map out how PostgreSQL row storage really works.
One of the biggest arguments against running automatic formatters
against a codebase is that we lose the benefits that git blame
gives us.
Fortunately as of v2.23, gitgained the
ability
to ignore specific revisions. This allows us to run our automatic
formatters without losing any information
Anyone who knows me, or who has read my work, knows that I can not
shut up about Kubernetes. In fact, they are probably part of a
betting pool about how often I say that word.
I am not sorry, though. The abstraction it offers makes my
job far easier
and, in general, it is a reliable force-multiplier for any DevOps
team. With anything, however, we have to take the good with the bad,
and Kubernetes presents plenty of formidable challenges for new
users trying to learn how to use it. In my 3+ years of working with
Kubernetes I have faced several such trials, with a couple standing
out as very memorable headaches. As a word of caution and guidance
for new folks, I have compiled a list of what I think are the worst
Kubernetes nuisances.
In the morning I saw the cat that had visited us a few times in the
front of our house. I called it and let it inside. It's a beautiful
cat and very friendly. It started to visit us earlier this year.
If you're anything like me, you love emojis! Emojis appear like an
image on the screen, but they aren't an image like a PNG or
JPEG. What do emojis look like to computers?
The Foundation sponsored feature reflows existing data to rewrite it
onto a new arrangement of disks thereby freeing space at the end of
the logical RAID-Z group
The FreeBSD Foundation funded the project to ensure the completion
and release of an easy-to-use and practical application. The project
came in under budget despite delays caused by the pandemic. The
feature was developed by Matthew Ahrens and is now completed but not
yet integrated.
The purpose of this overview is to introduce the feature and explain
how it works.
The CSS text-indent property is used to offset the first line of
text in a text block from the parent element’s inner box (the
content area). It behaves like the padding-inline-start property,
but only for a paragraph’s first line of text. It’s meant to allow
your design to e.g. indent the first line to designate the start of
a new paragraph (a more compact alternative to separating paragraphs
by empty lines).
The text-indent property has some additional uses with negative
values. In this article, I’ll explore how the property can be used
to implement hanging punctuation and list item markers. I’ll also
discuss how difficult it is to know how many pixels to subtract for
the desired effect, and how you should implement it instead. Some
familiarity with CSS syntax, layout concepts, and common properties
is assumed.
Time-series data is ubiquitous in almost every application
today. One of the most frequent queries applications make on
time-series data is to find the most recent value for a given device
or item.
In this blog post, we'll explore five methods for accessing the most
recent value in PostgreSQL. Each option has its advantages and
disadvantages, which we'll discuss as we go.
I have long tried to get into the good habit of committing as I
develop. However, I often fell into the same scenario. On commit №4,
I would realise that I should have worked something differently in
commit №2.
Naively, my old approach was a combination of adding extra re-work
commits and different forms of git reset. git rebase to the
rescue!
The git rebase -i command was everything I believed had to be part
of git but didn’t know of. The -i flag is the ‘interactive’ mode
of git rebase. Which allows you to choose which commits you want
to rebase.
