Very intriguing. This might be the use for my e5-2430 V2 X2 server that's been lying around. DDR3 is (relatively) cheap now too. Could fit 192GB of RAM in it and play around for much cheaper than a new GPU.
It would be a shame to see Dropbox decline. They're the last big player to maintain a Linux sync client that just works reliably. I've tried to host Nextcloud and tried Syncthing as well, but Dropbox has always worked for when I just want the problem solved without worrying about something going down.
Interesting finding, but hardly fundamental. My fluids lectures taught that there's form drag ("pressure drag" in the article) and skin friction drag. The two trade off with each other depending on Reynolds number. Keeping the flow laminar reduces skin friction drag (suggesting smooth skin), but keeping the flow attached for longer (e.g. by inducing turbulence, or injecting air...) reduces form drag (at a cost of increased skin friction due to turbulence).
Reads like they've discovered a neat way to delay flow separation while maintaining laminar flow, but the underlying principles have not changed. "Smooth thing low drag" was never a rule and only works at certain scales.
I suspect those people lack the practical skills needed to construct such a table, and the time/motivation to create with their own hands instead of purchasing.
I also suspect the modern digital news cycle and potential lawsuits have impacted the levels of risk acceptable. In China, with devastation in living memory, the population are generally willing to take more risks, and there's less of a culture of litigation. Plus, there's always the government who can dampen any viral social media outburst.
Of course, some standards (fire safety) are important. Looser standards are allowable where the customer can make a reasoned judgement of risk.
It's counterintuitive, but I've heard an explanation that the alternative - they decide to dispose their cigarette into the bin full of flammable paper waste - is much worse.
Possibly also: in toilets antifreeze such as methanol diluted in water can be used for freeze protection at low concentrations but is flammable and hazardous at higher concentrations.
I would like this feature to save screen space, but what happens when a window isn't maximised? The menu bar items get orphaned? Or you have differing behaviour?
IIRC Ubuntu provided this when they introduced Unity -- quite a long time ago.
When the window is maximized the menubar was merged into the top panel, but when the window was not maximized it looked like a regular window with tilebar and menubar at the window's top.
Not long ago there was also a KDE extension to replicate this; however, since many GNOME apps moved away from menubars, this approach isn't that helpful anymore.
Except that we're on HN so it shouldn't really surprise anyone that I'm using these "expensive" tools to solder and correct 0402 and sometimes 0201 parts.
Effectively impossible without a stereo microscope.
I understand that you're trying to flex a bit to prove your point, but a 2-lead rectangular discrete and dead-bugging a QFN-24/28 are in entirely different spectrums of difficulty.
Edit: Apologies, in my head I was replying to a different thread. I would still say that if you're working at that scale you should deploy appropriate tools to make the job simple, fast and repeatable.
Doing work on extremely small parts without a stereo microscope offers extremely small returns once you've finished proving your point to nobody watching.
This sounds like an opinion written by a "clean hands" computer scientist. Electronic engineers have it easy with their soldering - mechanical engineers deal with much more stubborn oils, greases, metal swarf...
Isopropyl alcohol removes all the soldering residue. Personally, all it took is decent equipment and some practice to make soldering enjoyable. It can be frustrating at times, but usually the problem is (lack of) heat, flux or patience.
