Bicycle by Bartosz Ciechanowski: https://ciechanow.ski/bicycle/ - HN post: https://news.ycombinator.com/item?id=35343495

Bartosz has many great blog posts, maybe most famously the one on mechanical watches published in 2022: https://ciechanow.ski/mechanical-watch/

That Bicycle post is Pulitzer worthy - every middle school student should be taught that post in science.

As a cyclist for decades - I still learned a lot - how to put to words that which I had innate muscle memory knowledge of, but no language for.

The demonstrations are fantastic.

Hands down should get some sort of IRL award of meaning.

I forgot I had seen the watch as well... Man this guy is amazing!

Thanks for resurrecting these for me.

New amazing web security research by James Kettle:

Smashing the state machine: the true potential of web race conditions

https://portswigger.net/research/smashing-the-state-machine

The talk (on YouTube) is also absolutely brilliantly done.

James finds new vulnerabilities classes where others don’t even see potential for problems. Absolutely amazing!

Working With Discovery Trees: https://www.industriallogic.com/blog/discovery-trees/

Happened to see Paige Watson present about FaST Agile at the PhillyXP meetup group and then tried some of the concepts with my team at work to great success. We were looking for a good way to turn high-level product asks into actionable work and Discovery Trees fit the bill for us.

The Big TDD Misunderstanding https://linkedrecords.com/the-big-tdd-misunderstanding-8e22c...

GuB-42 · 2023-12-25T23:52:39

My opinion on methodologies is that if it is too often misunderstood, then it is wrong.

The entire point of giving a methodology a name and writing about it is to get everyone on the same page. So if people have different ideas on what TDD is, then people should stop talking about TDD until everyone agree what is and what is not TDD.

And only after everyone agrees, one should talk about the pros and cons and assess the success of the methodology depending on the situation. "you are doing it wrong" is not helpful.

Back to the article. I think not mentioning TDD at all would make it a better article.

quickthrower2 · 2023-12-27T00:55:01

They will all be misunderstood, unless the title is the manifesto. But since the title needs to be short, it won't be.

Another example: Nation State. I can't get a clear answer to what that really means :-).

Back to computers: REST is a great example.

MoreQARespect · 2023-12-26T10:45:46

I've had this problem with team vocabulary. Once one word gets used to describe 2 or more things it becomes impossible to roll back.

I tried banning a particular word once and coming up with 6 new words on the basis that you couldnt tell which of the 6 meanings somebody was using unless you used a different term for each one. That didnt work very well. People got too attached to the old, overloaded term.

Expecting an entire industry to stop using a term theyve become used to is not realistic.

thiht · 2023-12-26T10:25:29

TDD cultists are awful about that, none of them do TDD the same way and if you don’t like TDD it’s because you’re wrong and are certainly doing TDD wrong.

I wrote a short rant about it last week: https://dev.to/thiht/tdd-is-a-personal-practice-3o76

bhaney · 2023-12-26T00:20:53

Talking about it is how we figure out what to agree on.

throwup238 · 2023-12-26T02:16:32

The entire point of giving a methodology a name is making money off it as a tech influencer slash management consultant. Those people don't care one iota about whether everyone agrees or not.

tunesmith · 2023-12-26T00:09:43

The biggest missing element, in my mind, of the pro-"classicist" and anti-"mockist" view is that the practice of writing unit tests with mocking leads to refactoring your code until it works with that approach, which in turn leads to better-designed code. I don't like the emphasis of "yeah but refactoring code leads to needing to rewrite mocked tests", because if you've designed your code well, then the need to adjust an api boundary should be less frequent than the need to adjust the internal implementation details. Focusing on integration tests means you can get away with poorly designed code full of corner cases that your integration tests can't catch. Besides, "we can keep the fast feedback loop with parallel tests" really increases the demands on complicated tooling that breaks often.

plugin-baby · 2023-12-26T12:35:20

Thanks for the heads up. It’s 10 years old, but I hadn’t seen “Mockists Are Dead. Long Live Classicists.” before (https://www.thoughtworks.com/insights/blog/mockists-are-dead...).

The Classicist point of view resonates strongly with me - I’ve long considered mocking in tests to be a code smell, and only usually justified for stubbing external services or hardware.

DanHulton · 2023-12-26T02:37:51

You can only get away with poorly designed code if that's not caught in the code review. I'd argue that while that might be a nice side benefit of some testing practices, forcing you to rewrite your code isn't relevant to the test - in fact the opposite! Your tests should work irrespective of your code's internals!

(Also, you can easily run integration tests in parallel with a little planning and attention to detail. For example, if your IDs don't rely on a sequence (like UUIDs), you can generally run them in parallel regardless of database connections.)

tunesmith · 2023-12-26T03:57:59

> forcing you to rewrite your code isn't relevant to the test - in fact the opposite! Your tests should work irrespective of your code's internals!

Are you avoiding rewriting your code so you can write integration tests, or are you writing integration tests so you can avoid rewriting your code?

Those that have been around the block of refactoring code so you can write good unit tests, tend to realize that the better-designed code isn't a side benefit. It's the entire point. The test is the side benefit.

Integration tests should be avoided if the same coverage can be reached with a refactor and some unit tests. For instance, it's very common for components to rely on complicated combinations of state. For instance, imagine a nightmare component that has nine boolean state parameters. To integration-test every combination, that's 512 cases. But in cases like those, you might discover through refactoring that some of those state combinations can compressed. For instance, you might be able to refactor into three sub-components, each of which take three boolean parameters and return one boolean result, and where the parent component only depends on those three booleans, which can be mocked. So then in that case, you've reduced the amount of tests you need to write to 32 total... that's 1/16th the effort.

I mean, I know that in common practice, neither are done, and people just leave the component largely untested, and then get bug reports that they close as "Can't reproduce".

jimmaswell · 2023-12-26T01:22:53

> Now, you change a little thing in your code base, and the only thing the testing suite tells you is that you will be busy the rest of the day rewriting false positive test cases.

Never happened to me, and we use a lot of junit tests at work.

I don't see the value in "Do not isolate code". Isolating a single method or such is often necessary, especially a unit test of a Utils class. But I only tend to do this if the "user story" centric test cases don't end up covering everything.

xwowsersx · 2023-12-26T03:22:01

This is pretty good and much of it resonates with my recent thinking on testing (I seem to revisit this topic every few years and rethink testing in general). I appreciate that it's pragmatic and not dogmatic. There's a lot of "tradition" in testing that has kind of built up over the years and not a lot of questioning the assumptions. Thanks for sharing.

Another shameless plug. I'm pretty proud of my Learning Zig series (1). It's been translated into Chinese, Russian and Korean.

Some may know my other writings (e.g. Little Go/Redis/MongoDB Book). I don't feel like I captured Zig quite as well, but it's hopefully a useful resources especially if you're coming from a garbage collected language.

Paul Graham's Essays keep me amused during this winter season - https://www.paulgraham.com/articles.html They go way back, and I do expect(and look forward to) new content.

Came across them via multiple sources, but what got me hooked was a reference from Robert Morris' work.

Kinda funny to reference this here :D.

I wrote a lot of articles on fundamentals (verifiable time estimation, leverage points with systems theory, using the Kelly criterion to shape project portfolio, system observability, evolution, etc.) with the intention of ending up on lists like these. None of them gained much traction, which means I need to get better at condensing the key points.

In the end, I think my most popular article of the year ended up being a relatively short note on how Bill Tindall approached software development for the moon landings: https://two-wrongs.com/tindall-on-software-delays.html

teaearlgraycold · 2023-12-26T04:37:40

I really like the "culture matters" and "look stupid" posts. I've been allowing myself to look stupid since I was a kid in school. Dan is humble (frequently saying things such as "If an idiot like me can [do X]"), but I think this strategy requires a certain degree of intellectual security. For me the logic isn't just "this question may sound stupid but the knowledge gained outweighs that". It's also "this question may sound stupid but anyone who thinks I'm dumb is wrong".

Like some of the renegades in the comments, I'm tempted to share an entire blog. Instead I'll share some highlights from my favorite blog of 2023. It's not tech-focused per se, but rather politics/policy by a former "Last Week Tonight w/ John Oliver" writer and EPA speechwriter, Jeff Mauer. The blog is called "I Might Be Wrong".

This is going to be a shameless plug of my own writing, not even technical but I needed to put it down in writing, so I did.

I found Timers to be a perfect tool to free up my brain and reminding me when I need to do something else. Making tea but I need to walk around, or do something else; timer on and I can get back to the right brew that I wanted. Browsing HackerNews but I need to get out after a specific time; timer on and I can get out.

Start a Zoom meeting but the attendant(s) are missing; timer on for 5 minute increment, then decide to ignore/cancel the meeting in either 5-min or 10-min.
