I'm also looking for a decent (ideally wireless) headset that works fine on Linux, with as good microphone as possible.

Currently I have - wired Sennheiser PC 350 SE - mic quality is good - Sony WH-1000XM3 - mic quality is mediocre

I'm quite happy with my Sennheiser, but now more and more often I have noisy environment around, so I would prefer to have noice canceling + be able to walk around the flat when I'm on conf calls.

My understanding is that right now, even with BT 5.0, I shall not expect a high quality codec as all duplex profiles (HFP/HSP) use low quality codes (ref: https://habr.com/en/post/456182), but I would be OK something with a dongle too, as long as it works OK on Linux. I was contemplating EPOS Adapt 560, but after watching many tests by CallOne (https://www.youtube.com/c/CallOneInc/videos) I'm just not too impressed. And also, I have no idea how those will work on Linux... Any recommendations?

> I don't see how this is any different from a regular server rack

well, the difference is that most rack cannot fit 10 TB of RAM and 140x5GHz cores: http://www-03.ibm.com/systems/z/hardware/z13_specs.html

but surely those are super-expensive and I doubt all that effective when it comes to performance per watt. I'm actually a bit more excited about Power8 servers, but are there any non-IBM available yet?

and when you need something between 1.25 and 1.5 available from UI, you can always do:

  document.getElementsByTagName('video')[0].playbackRate = 1.35

does it? It works for me: "Open Torrent", paste magnet link, click upload.

full blog post with video (was on HN already once or twice) http://www.joyent.com/blog/linux-performance-analysis-and-to...

with html5 player:

  document.getElementsByTagName('video')[0].playbackRate = 2

well, there are memoryviews, but they could have been designed better

just enable html5 player and you can choose 1.5 on youtube. Or, if it too fast (depending on the speaker), just do:

  document.getElementsByTagName('video')[0].playbackRate = 1.3

but NYT, why some stupid equation on the top? http://commandcenter.blogspot.com/2010/08/know-your-science....

Well, this is pretty basic stuff, for people interested a little bit more in NumPy I recommend SciPy lectures: http://scipy-lectures.github.com/intro/numpy/index.html http://scipy-lectures.github.com/advanced/advanced_numpy/ind...

Here is a pretty nice example how to use Numba and some expectations about the speedup you may get: https://www.wakari.io/nb/travis/numba

That's why for apps like this (not for projects that I create with virtualenv) I much more prefer using OS package manager. Could it be any nicer than on Gentoo? ;]

Well, probably I would have to bundle whole portage tree, so it would be ~1 GB big, but I'll give it a shot this weekend.

Regarding non-synthetic benchmarks, quite recently I've tested pypy as a "backend" to Gentoo's package manager (portage). System was quite not up-to-date, lots of packages and dependencies, this is how much time did it take portage to figure out what to update:

  python2.7: 323.13s user 6.50s system 99% cpu 5:30.59 total 
  python3.2: 271.40s user 6.33s system 99% cpu 4:38.64 total 
  pypy1.9: 168.28s user 5.95s system 99% cpu 2:55.16 total

AFAIK, tests are prepared by some third party organizations (psychology departments?), scaled on representative sample of the population and are just bought by Mensa(and changed every couple of years). You should be aware that in different countries test with different SD (15, 16 and 25) are used. I heard from one guy who was responsible for testing in my country that about 25% of people taking the test get accepted
