DerDangDerDang··on When Plants Go to War
There’s a fantastic board game on this theme, for anyone interested in such things.

Players can only grow their plants or spread seeds in spaces that receive light. Plants obscure light, the bigger the plant, the bigger the shadow area. The sun moves around the board each turn. All this means some very simple rules lead to some wonderfully complex emergent gameplay, where you’re trying to time actions against the sun’s movement to maximise light intake, while having to deal with other player’s actions unpredictably altering the patterns of shade.

DerDangDerDang··on Darling: macOS Translation Layer for Linux
How do you pronounce png? (no googling!)
DerDangDerDang··on Ask HN: How do I help an underperforming team get on track
Set the expectation that everyone will demo their work sometime around half way through the sprint. That way everyone knows they’ll be showing something and so will have to think earlier about how ‘done’ they really are, what visible progress they’d like to be able to show, etc. But there’s no expectation anything will be more than half finished at demo time, reducing stress and giving early visibility.
DerDangDerDang··on UK government to “opt out” of parts of the European convention on human rights
Stay classy uk.gov
DerDangDerDang··on Ask HN: Does karma give any privileges?
This sounds like a question that may have been asked frequently in the past
DerDangDerDang··on Ask HN: Anyone else get “pixel vision”?
Sounds like entoptics? https://en.m.wikipedia.org/wiki/Entoptic_phenomenon
DerDangDerDang··on Health Insurance Shouldn't Be Tied to Employers
It’s not ‘the rich’ paying in that case. It’s ‘the majority’.
DerDangDerDang··on I deleted my Facebook, WhatsApp, and Instagram accounts, and felt great since
Gamification helps. Unfollow as you scroll through the feed for a different sort of dopamine hit ;)
DerDangDerDang··on Receiving images of Earth from satellites with software defined radio
A teacher I had told a story about using this (or something very similar) with students in the 80s - they were asked (by the U.K. govt he said iirc) to destroy pics they’d got of the Chernobyl area around the time of the disaster.
DerDangDerDang··on A picture book written in C code
I was hoping the pictures would be procedurally generated by the c code
DerDangDerDang··on Guitar Decomposed: 5. Mutating the Third
Not metal?

Go listen to some of Dimebag Darrell’s solos. They sound ridiculously bad if played in whole semitones. Fair enough, he’s fairly bluesy. But other genres of metal give the distinction you give the left hand to the right too - variations in pick attack wildly change the sound.

I’m guessing it’s fair to suggest that similar things exist in all genres of music, and on all instruments.

DerDangDerDang··on Saying Thank You to the NHS, Using Clojure
It is nice. Thanks, I was genuinely curious - I hadn’t seen or heard of it before the Queen mentioned it. Rainbows seem a slightly naive choice in that case but if it’s an organic grass roots thing that’s pure chance, of course.
DerDangDerDang··on Saying Thank You to the NHS, Using Clojure
Did anyone hear of this rainbow = NHS thing before the Queen’s speech?

I ask because surely most of the country knows the existing connection between the rainbow symbol and LGBT issues.

Like, areas of my city painted roads in rainbow colours several years running to show welcome and support.

I’m vaguely wondering whether the rainbow was deliberately hijacked, in the same way as the phrase ‘postcode lottery’ was repurposed by the right.

DerDangDerDang··on Qt, range-based for loops and structured bindings
same here, despite knowing who kdab are and enjoying their articles in the past!
DerDangDerDang··on Several grumpy opinions about remote work at Tailscale
fwiw I’ve never had working audio in slack video calls on mac
DerDangDerDang··on Low-cost Deterministic C++ Exceptions for Embedded Systems (2019) [pdf]
I'm afraid not sorry. Though it probably wasn't a great benchmark. They were only investigating whether enabling exceptions has a cost if not thrown on MSVC. So a single example where there was a penalty was enough to cast doubt on exception usage. Enough that nobody felt like sticking their neck out to fight the cause, anyway ;)
DerDangDerDang··on Low-cost Deterministic C++ Exceptions for Embedded Systems (2019) [pdf]
Theoretically true, but colleagues of mine have done benchmarks showing MSVC has a slight overhead with exceptions enabled, even if none are thrown. Worth benchmarking yourself if you need to be sure.
DerDangDerDang··on Wrapping Images Around Fractals
Writing fractal shaders is great fun, agreed. I found mip mapping introduced artefacts around discontinuities in the texture coordinates - this was doing orbit trap texturing, but the UVs in the described method would have similar discontinuities. The artefacts can be reduced with a bit of care, iirc
DerDangDerDang··on Ask HN: How do you deal with depression?
I hope they help. For me the main take-away was that your brain needs rest, which is not the same as recreation. Be kind to your brain and digest in manageable chunks :)
DerDangDerDang··on Ask HN: How do you deal with depression?
I found these articles incredibly helpful in learning to help myself. I have no idea if they are factually correct, but the writer's way of reframing depression as a process or system was a great way to get some distance from my personal feelings in the moment, and allowed me to bring to bear familiar mental tools to help get a feel for the complexity.

The ASCII graphs on the 'stress system' are fantastic, the rest IDK. Caveat emptor.

DerDangDerDang··on ‘Get Ready for Brexit’ Campaign Launched
"Based on your responses, you do not need to take any action to prepare for the Brexit deadline of 31 October 2019."

Thanks, but I think I'll start my panic buying now - if only to avoid the rush.

DerDangDerDang··on Bulk Data Structures C++
It's not clear from the article, but I suspect the author is talking about what happens when the vector is resized and has to move existing elements, which is a real problem.

There are plans to solve this - http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p114...

DerDangDerDang··on OpenDrop: An Open Source AirDrop Implementation
I’ve found it very flaky on iOS - regularly try to transfer between my phone and my wife’s sitting next to each other and it will randomly not see the other phone or take minutes to find it :(

When it works, it just works.

DerDangDerDang··on C++20 Is Feature Complete; Here’s What Changes Are Coming
Absolutely! clang-tidy has a suite of modernisation tests and in many cases can apply fixes automatically.
DerDangDerDang··on Ask HN: What have the past 12 months taught you?
Can everyone biking?
DerDangDerDang··on Catching use-after-move C++ bugs with Clang's consumed annotations
References mean the optimizer cannot rule out aliasing, which is kind of a big deal.
DerDangDerDang··on Speedy Desktop Apps with GTK and Rust
That seems like a very bold claim on the face of it. Do you have any examples?
DerDangDerDang··on Kuo: Apple to include new scissor switch keyboard in MacBook
I much preferred the keyboard on my 2015 MBP to that on my 2018 Thinkpad. The newer Apples keyboards (including the wireless ones) are crap, I agree.
DerDangDerDang··on Ray Tracing with Metal [video]
RTX is a marketing term, not a new technology.

It’s not unreasonable to expect people to buy a commercial licence if they’re releasing to a commercial app store
