“History has no mercy. There are no laws in it against suffering and cruelty, no internal balance that restores a people much sinned against to their rightful place in the world. Cyclical views of history have always seemed to me flawed for that reason, as if the turning of the screw means that present evil can later be transformed into good. Nonsense. Turning the screw of suffering means more suffering, and not a path to salvation. The most frustrating thing about history, however, is that so... [More]”

As I was reading the absolute train wreck of a unit test in Testing with a Lisp (Daily WTF), the song “What the fuck is going on?” popped into my head, like it always does when I see that a programmer not only didn’t understand the assignment, not only doesn’t know how to program, but also doesn’t know that they don’t know how to program.
They are living their best life because they don’t think that “knowing how to program” is required in order to be a programmer. Neither does their boss or team, I guess.... [More]

A major bank in Switzerland has an MFA that uses PhotoTAN. It took me dozens of attempts over three days to finally be able to register the app.
This isn’t the first time that this has happened. I’d reset my phone in July and I’d had to go through this for a couple of days then. When my partner reset their phone in August, it took days to register. In September, I’ve moved into a new phone and had to set up the app again.

I was recently asked something like the following question, which I am citing with a few minor edits.
We would like to do a course about SW development with Python, preferably an online course, so that we can start at our own pace.
We don’t want a Python course, but would instead like a course more about SW development. It would be great if it were in Python because we are comfortable with it.
The interesting topics would be:
- object-oriented programming
- functional programming
- design... [More]

Note: I found this old draft containing my response to a colleague.
I 100% agree with you, in general. I absolutely want to know immediately when an assumption I’ve made does not hold.
But…😁
The degree to which I’m willing to crash depends on whose consistency I’m basing my assumptions on. When I call a method in my code from another method in my code, I’m absolutely going to assert that an argument is not null. I can control that. My IDE will tell me when I might be passing null. That... [More]

This article is a copy of the white papers and process description that I wrote for Encodo Systems while I still worked there. I’ve preserved a copy of it here and in the linked articles.
Through our many years of experience building software, we’ve accumulated methodologies and principles that lead to quality software.
Published on in Programming
Encodo keeps the SOLID principles in mind when designing software.
We implement the Inversion of Control [I] pattern with the dependency-injection pattern (D) to allow for a large amount of flexibility in how an application is composed. We’ve applied this principle throughout the Quino framework and use it in our products as well.
What does this mean? It means that the product or framework doesn’t make any decisions about which exact components to use. Instead, it indicates the API... [More]

These are the two core principles that guide how we write code:
This first principle is a constant reminder to ourselves to avoid the seductive call of cleverness. Most code does not need to be clever. Very occasionally, it is necessary to implement something with real flair, that requires explanation.
The best code, though, requires no explanation. The best code gets its job done in a very boring way, using the same... [More]

Tests are code. Writing tests is not a “step”—it is part of writing the code itself. The component is nothing without its tests.
It should be easy to verify any requirement with a test. The tests should tell the story of the requirements.
A developer can test any component in isolation (unit testing) or can test the component in the constellation in which it normally exists (integration testing).
Just so we’ve said it: tests are not a place to use a different coding style... [More]

Good documentation is part of every piece of quality software. What do we mean by “good”, though? Or “documentation”, for that matter? Quality software should be self-explanatory, but don’t be fooled into thinking that you don’t need to write documentation.
Documentation has an audience. Before writing anything, consider who you’re writing it for. What are the possible audiences?
Evaluators are interested in what your software does, how it interacts with other... [More]

An important part of the software process is the final step: delivery.
If you can’t get your software into your customer’s hands, then what’s the point of writing it at all?
There are several at-times cross-cutting goals. In descending order of importance, they are:
There are several aspects to continuous... [More]

Design by Contract is a software engineering practice in which software requirements and promises − the “Contract” − are explicitly written into the code. The code is, at the same time, better documented, more reliable and easier to test against. Encodo uses this technique to ensure software quality.
A software contract is composed of several components: preconditions, postconditions and invariants. Preconditions are what a component requires of a client, whereas... [More]

A healthy and active review culture is essential for any team interested in building quality software. At Encodo, we’ve been doing reviews for a long time. They’ve become an essential part of everything we do:
What we mean by review is not a formal process at all. It is simply that you prepare work you’ve done for an informal presentation to a team member. Explaining what... [More]

This article is part of an archive of Encodo White Papers.
What is the best approach when designing a new application, be it a small tool or an end-user application?
Many developers jump straight into a prototype, in order to get a feel for how the application will work. While prototypes are good for demonstrations, they are dangerous: in projects with tight time or budget constraints, the temptation to simply “build out” the prototype becomes irresistible. This leads to... [More]

Most people in the software industry have heard of test-driven development — it has become a buzzword with several possible meanings.
One of the more negative associations is the notion of unit testing. Unit testing traditionally involves writing a test for each and every routine in a unit or class, to ensure that it does what it claims. This practice has, of late, declined in popularity — mostly because of the sheer mindlessness of maintaining complete... [More]

The interview The Great Reorganization of Sexuality and Gender by Hugh Ryan (This is Hell!) is quite an interesting discussion, which ranged over some absolutely terrible characterizations of what the concerns of so-called right-wingers are, as well as seemingly obstinately refusing to acknowledge the modern-day use of the word snowflake, instead clinging to a 19th-century definition, as well as completely misdefining the Dunning-Kruger Effect, and misusing “strawman argument” for good measure. Then he uses the phrase... [More]

These are my notes to remember what I watched and kinda what I thought about it. I’ve recently transferred my reviews to IMDb and made the list of around 1600 ratings publicly available. I’ve included the individual ratings with my notes for each movie. These ratings are not absolutely comparable to each other—I rate the film on how well it suited me for the genre and my mood and. let’s be honest, level of intoxication. YMMV. Also, I make no attempt to avoid spoilers.

The article Drug makers have tripled the prices of top Medicare drugs by Beth Mole (Ars Technica) writes,
“Overall, the average lifetime price increase for the top 25 drugs was 226 percent. The highest increases were seen in drugs that have been on the market the longest. For example, drugs that were on the market for under 12 years had an average lifetime price increase of 58 percent, while those on the market for 20 or more years had an average lifetime increase of 592 percent.”
These are medications to help people.... [More]

The always-entertaining Patrick [H] Willem made two excellent videos about the state of filmmaking and art, in general. The first one discusses what people are calling AI films, focusing on the recent spate of so-called Wes Anderson AI remakes.
There’s not a lot of my own, original writing in this article. Instead, I’ve done the service of transcribing what I found to be the pithiest, hardest-hitting parts of Willem’s two rather long videos, which total more than 90 minutes.

Complexity: Divide and Conquer! by Michel Weststrate on May 7, 2017 (YouTube)
“Can we make our UI dumb enough to make our app usable without it?”
The video demonstrates navigating through a simple e-commerce site. Then, he shows how the app can be driven from the console by calling the APIs directly—upon which the URL and UI all update automatically. That is, the logic is not in the UI.
He then demonstrates that he can drive the web site without a UI by deleting the rendering to React DOM entirely. He can still manipulate the console API to perform the same... [More]

The article US Colleges and Universities Are Becoming Giant Exploitation Machines by Daniel Denvir & Dennis M. Hogan (Jacobin) writes,
“[…] there are schools like Yale or Princeton, frankly, that have the latitude such that they could pretty much send people to school for free. But in spite of that, they continue to overwhelmingly enroll wealthy students.”
And it’s not merit-based; they’re laundering privilege into credentials. That’s their business.
“They’re going to end up graduating students with more debt who also have... [More]”

The article Let Me Reiterate the Questions I Asked in My AOC Essay by Freddie de Boer (SubStack) writes
“Ocasio-Cortez is not treated like a legislator, but like an icon, a sacred cow who can’t be criticized where any back-bench fifth-year representative would be for similar behavior. I don’t know what that is, but it’s not progressive.”
This is a not unusual idolization of a person who is seen as a bulwark against things ostensibly even more evil. But, as listed in concise detail in the linked article, there are... [More]

Oh, c’mon, Bernie. Really?
The article In New Hampshire speech, Bernie Sanders seeks to give Biden “progressive” credentials, comparing him to FDR by Patrick Martin (WSWS) reports on Sanders’s latest disappointment. The article basically provides detail for what it says on the tin.
Specifically, he said this:
“The Democrats, once and for all, must reject the corporate wing of the party and empower those who are prepared to create a grassroots, multi-racial, multi-generational working class party in every state in... [More]”
