I hear a variation of this type of thing from windows fans constantly. "It's your hardware's fault." But never Window's fault. My experience is this; most of my computers are dual boot with windows and linux. When I have a problem with windows, I'll boot into linux and the problem goes away. Same hardware.

I got stumped at the Frobenius norm (11/13). Everything I typed in returned this:

NotImplementedError: the 'axis' parameter is currently not supported on line 7

I used variations of: np.sqrt(m.sum(m.prod())) np.sqrt(m.sum(m2))

It's been a long time since I've taken linear algebra, so I don't remember some of these operations.

What's the political situation like there? I hear about things like voter suppression by the Republicans and other shenanigans in those states.

Arch looks like it's got a lot going for it, and I sometimes find myself looking at their documentation when I'm trying to shoehorn a package into ubuntu. Even though I used Gentoo linux for a long time, very similar to Arch in lots of ways, I haven't been able to install and configure Arch successfully on my computers. I'm sure if I spend a lot more time on it, I'll be able to do it, but I just don't have that much time to spare, so I stick to ubuntu and variants. But I really do like what I see on Arch.

I've been using Ubuntu and variants for a long time now. I find lubuntu is ok and small in terms of size. As for older computers, I must have some really slow ass hardware, because even lubuntu is kind of slow on some of my hardware. I stick to standard ubuntu on my desktop just to see what it's like, but prefer xubuntu because I prefer the DE over the gnome crap. I'm used to the more standard keystrokes and shortcuts that you see on windows and the IBM standard which gnome wants to ignore. It's also tough to customize gnome to how I like to do things.

New comment by aceperry in "Ask HN: Why is Bluetooth so unreliable?"

aceperry — Sat, 18 Apr 2020 02:25:18 +0000

#4 makes me laugh because I had that thought when I was trying to work with bluetooth. I think the real problem is two-fold. The original spec required approval from all members of the consortium. I think a lot of things were left out that are really important, such as security. I know they had security from the start, but really, it's bullshit. Plus the original chipsets were incredibly expensive, and my pure speculative thought is that they cut corners (the firmware part) to bring them out to market. I was really surprised, shouldn't have been with hindsight, to see when bluetooth chipsets started to reach price parity with wifi chipsets.

The second thing is that much of the low level firmware for the stack is closed source stuff that is written in house. I suspect, after working with some of that shit, that it's poorly done and is a major cause of unreliability. Don't know if it would make any difference if it was open sourced, because the hardware/software combo is a lot like what you see with graphics cards. Everyone has their own secret sauce and they don't want to show it to the world.

What kind of documentation do you look at, and how do you document that sort of thing?

There are a few other open-source and crowd-source projects like this that I've seen. It's interesting to see so much volunteer response to the crisis.

New comment by aceperry in "After years of Google Chrome, Firefox was a pleasant surprise"

aceperry — Thu, 12 Mar 2020 06:20:49 +0000

Interestingly, I had the opposite experience. I've been using Firefox for many years after moving away from Chrome because it was too slow. Nowadays, I've been thinking about moving back to Chrome because I tried a recent version of Chrome, and it ran faster than FF. FF does have some nice features like privacy and some really cool extensions. But it's gotten slower and there are some webpages that don't work for me unless I fire up Chrome. But since I've been using FF for many years, and have all of my favorite extensions and logins saved, it's tough to go back.

I like the spacing better than the other fonts, but the lowercase 'r' is pretty nasty looking. I can't get over that, nor do I think I can use it.

Not only that, but uber and lyft copy each other's prices. When one of them lowers the pay to drivers, the other one follows soon. Usually, the pay to drivers is lowered, but the cost to riders doesn't go down as much, and uber/lyft has been taking much more from drivers, especially the 'surge' surcharge. Much less of that goes to the driver than before.

Nice looking. That's what the windows terminal should have been like. I've always thought that they made the windows terminal ugly and hard to use because they wanted to discourage using the command line in favor of the gui.
