You often need a web interface for your Raspberry Pi projects. Flask is a Python framework that makes it easy to program web APIs. Then you need to add all the deployment steps to automatically run the Flask application. Here I want to show how you can do this with Gunicorn, Nginx and systemd.

Spurred by a conversation with a whip-smart friend and fellow gentlenerd, who unreasonably believed (believes?) they have nothing worth speaking about at the software conferences we like (IN/Clojure, FunctionalConf, local meetups etc).

In part 2 of this series, we'll look at the Serverless Development Kit (SDK) and see how our interfaces are used to make development faster and automatically create infrastructure.

Background I find it quite easy to handle views different from my own. I feel more troubled when I see people agree with me for the wrong reasons. It’s no secret that I’m a passionate supporter of software freedom: I’ve written two posts about how Free, Libre, and Open-Source software (FLOSS) is necessary but insufficient to preserve user autonomy: Whatsapp and the domestication of users The phenomenon of a class of predatory busines....

Who among us doesn’t love Wordle? No one, that’s who! It’s gotten to the point that the NY Times announced they are purchasing the original Wordle from its author. There have been a bunch of copy-cats, both in app and web-app form. And, some of these have been up to no good!

Twice a year, NextRoll celebrates Hack Week, where employees get to work for a week on a project of their choice. It’s an excellent opportunity to experiment, learn new technologies and team up with people from across the company. You can learn all about Hack Week here . As NextRoll increasingly adopts the Rust programming language, it’s common for engineers to use Hack Week as an opportunity to gain experience with it. Another popular ....

Following the abandon of Google Analytics and the beginning of umami usage (you can read the details in this post ) I encountered in a little trouble: how to make a backup of the umami database, without having sFTP access to Heroku VPS, because of the free plan? I’ve found a solution that is a bit tricky (compared to a normal backup) but it works. It requires having Heroku CLI installed, can be done via

Postgres supports three types for "schemaless" data: JSON (added in 9.2), JSONB (added in 9.4), and HSTORE (added in 8.2 as an extension). Unfortunately, the performance of queries of all three gets substantially slower (2-10×) for values larger than about 2 kiB, due to how Postgres stores long variable-length data ( TOAST ). The same performance cliff applies to any variable-length types, like TEXT and BYTEA . This article contain....

Intro It turns out we have several folks at Square who arrived at programming through boot-camps, or other non-CS paths, and feel a sort of lingering insecurity (or get explicitly told by unkind people) that their path left them without a solid grasp of “the fundamentals”. I have the pleasure of having a boot-camp grad on our team, Amy Henning : she’s now several tech jobs in (and fantastically capable), and has a great perspective on w....

This post compares MAD and the Shamos estimator across various distributions and sample sizes. Pragmastat adopts the Shamos approach as Spread — a more efficient robust scale estimator with a 29% breakdown point. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat There are multiple ways to estimate statistical dispersion. The standard deviation is the most popular one, bu..

I remember hearing about Bogan Ipsum, which was an alternative to Lorem Ipsum for you know bogan’s back in 2011 through LifeHacker . However it since became defunct. I became aware of this fact from Darren at work given the following message on slack? Dude Boganipsum where? Clearly this needed to be rectified! A quick search found this https://www.npmjs.com/package/boganipsum implementation which seemed to work well enough, so ..

For those unfamiliar, Artsy is a fine art marketplace. Knowing that, it follows logically to say that the form via which our partners list artworks for sale is an integral part of Artsy’s core systems. This form, known only as “The Artwork Form,” is whispered about in the halls of Arty’s New York headquarters. It is legendary. It is a colossus. It is old enough not only to predate React v16.8 hooks and context APIs, but Artsy’s use of React....

One of the great things about Kindle readers is that you can read old books for free. You can grab an epub from places like Monergism , Gutenberg , Standard Ebooks , or Planet Ebook , and side-load them into your device. The problem is that Kindles don’t support epub files, and so you have to convert them to something it can read. Historically, the advice has been to convert your epubs to mobi files. However, in 2022, the mobi file....

Infinite Race is a mathematical racing game. Two players compete to move their piece the greatest distance along the number line by choosing how the dice will fall. However, the rolls must fit a distribution perfectly, so the player’s luck must revert to the mean. The strategy is to select a sequence of moves which allows one player to break free of the pack. Setup Each player specifies an infinite sequence of moves at the beginning of p....

Many "must-read" books are not well-written. I try to read a lot , but I still have a low tolerance for bad writing and bad editing. I write this post both to discourage thoughtless recommendations and to encourage the receivers of bad recommendations. For software developers, Structure and Interpretation of Computer Programs is a prime example. Written for freshman at MIT, it is ostensibly an entry-level text. But it requires such a lev....

When you design software to achieve a particular level of performance, it can be a good idea to be familiar with the general speed regimes you are working with: fundamental limitations like storage devices and networks can drive software architecture. Here are a set of common benchmark numbers that can help you anchor performance conversations and think about the components that your software will interact with. As with all guidelines, thes..
