I used perl and PDL heavily, before moving to Python and numpy. Both have annoying issues, and oddly, their warts are complementary. Particularly, the core API in PDL is miles better than numpy's. Before I could tolerate actually using

That's excellent! Thanks for posting. I've seen most of the tools in this area, and visidata is a new one to me. And it actually does lots of things the others do not.

And yet another set of tools is vnlog ( https://github.com/dkogan/vnlog ). It assumes you have whitespace-separated data, with a legend comment, then you can do the above thing with < data.vnl vnl-filter -p thisco

Not all of us, probably?

Gnuplotlib can do it just fine. https://github.com/dkogan/gnuplotlib/

Yes. I've been doing this for years. It's the only way to go.

4:3 is what you want. That's what all laptops used prior to ~ 2002 or so. You only get "letterboxing" if you view content specifically designed for wide screens; i.e. movies. I don't do that often. Maybe 1:1 is what you

They had a software glitch, and the flight was pushed back a few days while they investigate.

Ah. The follow-up question would be "how do you do that without root access?" But I now see that the docs say root access is required. I was hoping you'd have some magic way that didn't require it. Thanks for replying

Does anybody know how/if this deals with /dev and /proc and /sys and all those? Usually you need to separately bind-mount these in your chroot.

That's the thing about the non-mrcal tools: they don't give you good feedback. The pixel errors do NOT indicate uncertainties. You can trivially prove this to yourself: throw away lots of your data and re-solve. The pixel errors t

I've never used this on those boards, but there's no reason it wouldn't work. On some level the RPi is just a computer.

This is for stereo vision, structure-from-motion computations and so on (i.e. figuring out the geometry of what you're looking at from photos). Every lens that is manufactured is slightly different, and has a slightly different ray-in-

Yeah, it supports opencv models, so just take the numbers and feed them to opencv. Call cameramodel.intrinsics() to get at them: http://mrcal.secretsauce.net/mrcal-python-api-reference.html...

There're lots of tools that do this. The primary thing mrcal does that others don't is reporting uncertainty and accuracy numbers. hugin is great at making panoramas that look nice, but not so much at making a map.

Did YOU read the article? This average speed included hours of stops to charge, so the average moving speed was much higher.

Or you can do this in general: ping 8.8.8.8 | perl -ne 'BEGIN {$|=1;} s/.*=([0-9\.]+) ms$/\1/ && print'| feedgnuplot --stream --ylabel "Ping time (in ms)" --lines Advantage: works for ANY in

What issues did you have debugging assembly? I've done it somewhat, and it SEEMS to work ok.

by dima55 6y ago
Yeah. TRAMP is magical, and everything just works. And has for years and years.

In case you're not aware, that site is run by an ex-Debian-dev with an axe to grind. He's been proactively trolling the project for at least a year now. The project has its issues, but let's be very clear: this is one troll w

If this thing isn't free software, and if one really cares about MSword compatibility, then why wouldn't they just go use MSword?

It talks about bash workarounds for zsh features.
266.
by dima55 6y ago
Do you actually use zsh? C-o and M-q and M-a and M-h and all the others are really nice, and as far as I know bash has nothing similar (correct me if I'm wrong). You don't NEED any of these niceties but they're very nice.

You can use gnuplotlib to use gnuplot as a plotting backend to visualize numpy data

Yep. Plenty of real things to argue about.

Of all the things to complain about, this one is just silly. You can use ; instead of TAB. There. Problem solved? Do you like Make now?
