I'd say good music is objective. Whether it's hard to play, uses complex polyrhythms etc. which most listeners aren't even aware of - and those people tend to think good music is subjective as they can't perceive the quality, only whether they like it or not. There's also some incredibly skilful metal music with no "shredding" whatsoever.
I don't particularly like Mozart but I'd be an idiot to say it's not good music. On the other hand most people agree Taylor Swift does not make good music, having released lots of samey 4 chord songs with incredibly simple melodies, but she's one of the most listened artists of all time.
Never worked for me, I think if you're physically fit, being physically tired has no correlation on sleep. Since 12y/o I've struggled to sleep before 1-2am, and since 14y/o I've exercised a frankly ridiculous amount.
14-18yo I went to the gym 1hr/day every weekday, boxing 1-2hrs 3x/wk, karate 1hr 2x/wk.
18yo+ I've boxed, run 30-40 miles/wk (some 3/4hr runs in there too leading up to ultras), climbed 2-10hrs/wk, and gym 2-3x/wk for the last 5 years although that schedule and activity level has varied since I have no real reason to kill myself training now that I don't compete in anything.
None of the above have an impact on sleep or ability to fall asleep, I have taken weeks off due to injury or months off due to burnout after a 12hr race, and my sleep schedule hasn't changed. Still tired-ish around 5-7, then 7-2am find it impossible to fall asleep, followed by 5-6hrs sleep and repeat.
I 100% agree with the guy who replied to you that got heavily downvoted that "just exercise" is a vastly oversimplified response to the complex issues most people have with sleep. Not everybody's sleep issues are due to an inactive lifestyle, and I'd bet that is not the case for the majority of people.
The free version doesn't allow GPU accelerated playback or editing or rendering which is a must for any serious user / business.
They get people in the door with a really powerful free editing software, and once you've invested time into learning it and made it part of your workflow, you want to pay the £300 to upgrade because it's too much hassle to learn a new editor, and Resolve is awesome, but you reallly don't want to keep waiting 3hrs to generate 1/8th res optimized media for your whole project before you can preview at more than 10fps on an i7 Extreme Edition (that's how they got me, if you couldn't tell).
It's an effective free -> paid product-led conversion path to acquire customers. Being on HN and presumably working in tech/SaaS, this is a familiar and effective business strategy.
Half my family now owns the small desktop sized sub-£200 Kyocera laser printers. It was honestly revolutionary the first few times I was able to connect to their WiFi, hit add printer on my phone or laptop, press print, and it just worked with no drivers or network troubleshooting or anything.
They completely blow any consumer inkjet out of the water in ease of use, not having to install bloatware with popups telling you to buy more ink and preventing you from printing black and white when the magenta ink is "only" at 25%, printing speed, and the fact they don't outright break forever if you go 6 months without printing (where an Inkjet would often get irreparably clogged and be ruined).
No validation, anddd this point from the article stood out to me:
---
The programming style is very imperative. Furthermore, the description sounds like the procedure is working directly on the textual representation of the flight plan, rather than a data structure parsed from the text file. This would be quite worrying, but it might also just be how it is explained.
---
Given that description, I'd be surprised if it wasn't just running a regex / substring matches against the text and there's no classes / objects / data structure involved. Bearing in mind this is likely decades old C code that can't be rewritten or replaced because the entirety of the UK's aviation runs on it.
According to that page, BAE systems et al were using kevlar soaked in a solution of polyethylene glycol and silica nanoparticles.
All readily available online, if you can afford something like $200 per 2ml of silica nanoparticles. It would be amazing to see one of the YouTube channels that has tried making their own, just make the real thing.
I imagine a suit made of dripping wet Kevlar wouldn't be too comfortable though. John Wick would experience some chafing.
