- With one quite significant issue IMO
If there's an old question the most upvoted answer will be at the top. Better solutions are often available if the previous answer was 10 years ago, but they will be buried.
Solution is obviously to scroll down as well as read the comments, but that can be time consuming.
- I do wonder how branch prediction actually works in the CPU, predicting which branch to take also seems like it should be expensive, but I guess something clever is going on.
I've also found G_LIKELY and G_UNLIKELY in glib to be useful when writing some types of performance-critical code. Would be a fun experiment to compare the assembly when using it and not using it.
- > Even with things like wlroots, you have to invest a lot more work to get even the basics working that X11 will give you for free.
Like what?
A few years ago I copied the wlroots example, simplified it to less than 1000 LoC and then did some of my own modifications and additions like workspaces. And this side-project was done in less than a week on my spare time.
- I work for a company with 1000+ people in RnD doing software development. 80% of those use Ubuntu and have one desktop and one laptop (HP EliteBooks) and that works fine.
You are right that not all devices don't work perfectly, but the Bluetooth headsets, Bluetooth mouses, conference rooms etc. that the company supports are tested for compatibility before being bought by our IT department.
- A lot of things are happening, this company is just doing a little part of it and that's alright.
China have ambitious plans to carbon neutral by 2050 and the US had plans to... ok maybe the US is a bit stuck for the moment but it seems like at least some states seem to care.
What's important is that people show that investing in environmental-friendly companies is worthwhile. Right now that is not usually the case unless there's some kind of state/government incentive. And no, incentives are not bad since the option of polluting also has a cost, the only difference is that the cost of polluting is a long-term loan that it growing and is already hard to pay off.
- > A professional can still replace almost any component of a modern laptop, with a few thousand $ of specialized tools, and the battery, the only component with a fixed lifetime, can be easily replaced at home.
Even if a professional can fix it, that expertise to be able to use those tools worth "a few thousand dollars" costs a lot too, likely pushing the price high enough that its worth thinking about buying a new device instead.
While the battery might be the only thing with a fixed lifetime, other components often also break. I was unlucky and owned a ThinkPad with one soldered on RAM module and one socketed slot to be able to upgrade the RAM, but that didn't help the day that the soldered on RAM died on me.
- While Sweden has free health care, it does not completely include dental care. It's free until you turn 20, after that you pay out of your own pocket. This is to incentivize people to take care of their teeth, instead of not caring and then expecting free replacement of your teeth. One you're 20, you only get a very tiny deductible on your dental care which equates to almost the exactly the cost of a single basic check-up once a year.
- I only personally know one person who had been an active member in Extinction Rebellion and I think it's a bit more nuanced than that. It seems like they all agree that the amount of growth we have today is unsustainable, but what sustainable growth exactly is and in turn how much growth needs to be compromised is not agreed upon. So I don't believe that endless pursuit of growth is against most of their members opinion, they just have a much stricter view on what sustainable growth is (and that some degrowth might be needed to achieve sustainable growth in the long term).
Currently only do that on one of my older devices, would love to do it on my main device but when I bought it I was in a hurry to get it going and did not have time to unlock the bootloader. Unlocking the bootloader now means having to factory default the device but I simply have too much important stuff set up that it's not worth it. Apparently there's also no great way to backup all partitions of the Android device which I find to be quite strange.
