[$] A look at terminal emulators, part 2

Post Syndicated from jake original https://lwn.net/Articles/751763/rss

A comparison of the feature sets for a handful of terminal emulators was
the subject of a recent article; here I follow that up by
examining the performance of those terminals.

This might seem like a
lesser concern, but as it turns out, terminals exhibit surprisingly
high latency for such fundamental programs. I also examine what is
traditionally considered “speed” (but is really scroll bandwidth) and
memory usage, with the understanding that the impact of memory use
is less than it was when I looked at this a decade ago (in
French).

[$] A look at terminal emulators, part 1

Terminals have a special place in computing history, surviving along
with the command line in the face of the rising ubiquity of graphical
interfaces. Terminal emulators have replaced
hardware
terminals
, which themselves were upgrades from punched
cards and toggle-switch inputs. Modern distributions now ship with a
surprising variety of terminal emulators. While some people may be
happy with the default terminal provided by their desktop environment,
others take great pride at using exotic software for running their
favorite shell or text editor. But as we’ll see in this two-part series,
not all terminals are created equal:
they vary wildly in terms of functionality, size, and
performance.

An elephant being eaten by a snake: Easter eggs on your Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/raspberry-pi-easter-eggs/

Grab your Raspberry Pi, everyone — we’re going on an Easter egg hunt, and all of you are invited!

Voilà, a terminal window!

When they’re not chocolate, Easter eggs are hidden content in movies, games, DVD menus, and computers. So open a terminal window and try the following:

1. A little attitude

Type aptitude moo into the terminal window and press Enter. Now type aptitude -v moo. Keep adding v’s, like this: aptitude -vv moo

2. Party

Addicted to memes? Type curl parrot.live into your window!

3. In a galaxy far, far away…

You’ll need to install telnet for this one: start by typing sudo apt-get install telnet into the terminal. Once it’s installed, enter telnet towel.blinkenlights.nl

4. Pinout

Type pinout into the window to see a handy GPIO pinout diagram for your Pi. Ideal for physical digital making projects!

5. Demo programs

Easter egg-ish: you can try out various demo programs on your Raspberry Pi, such as 1080p video playback and spinning teapots.

Any more?

There’s lots of fun to be had in the terminal of a Raspberry Pi. Do you know any other fun Easter eggs? Share them in the comments!
