Experimental nuclear and particle physicist. These days I'm teaching, but I've spent a lot of time on nucleon structure in fixed target electron scattering and neutrino oscillations using reactors and beam sources.

comment Linux less behavior and stderr
@cYrus: That works as expected for me, too. 'Course I tried in on a Mac OS box. Bash 3.2.17, less 394. Maybe something linux specific. In any case RedGrittyBrick's approach should work fine.

comment Transferring a large amount of data between continents
This comes up a lot in High energy physics. There was a time when the only cost-effective thing to do was write tapes and air freight them. Those days seem to be gone (for now, sometimes these things cycle) and a variety of internet based solutions are used.

comment sed parsing data: fields (words) separated with whitespace
sed may not be the best tool for this. Is ther a particular reason you don't want to use awk, or perl or something better suited?

My answer to stackoverflow.com/questions/528399/… gives a brief overview of the usual kinds of things done by make install steps from a programmers point of view.

comment Remove desktop environments cleanly
When you say "completely remove" do you include the underling libraries, and if so are you willing to lose those applications that rely upon those libraries without being integrated into the window-managers/desktops? Because tese things are delivered in a compoentized way, they can end up being deeply entangled with things that seemed separate. Indeed that is part of what distributions manage: the complex inter-relationships between various libraries, services and applications.

comment Mac OS X consumes so much memory
If you are not familiar with linuxatemyram.com, you should read it. Yes, it's for Linux, but the way of thinking about memory consumption applies to all unix-alike systems including Mac OS.

comment How to change the partition size without re-install the OS?
Not a programming question in any way. Better on SuperUser.com, but I believe that is has bee asked and answered there more than once already.

comment Is there something like Things for Windows?
It is helpful, when you are looking for an alternative to Foo to (1) say what Foo does (you can imagine a user reading this question who has the perfect solution, but has never heard of get things done...) and (2) provide a link to a more extensive resource. It would also help to say what features and interface elements you like. The better the question you right, the better your chances of getting good answers.

You remap the useless thing to control and relieve your emacs pinky in the bargin?

comment Is overclocking legal?
Apple tries to leverage the laws relating to software to maintain control of the hardware. That's not surprising, because they would very much like to have the world work that way, but they can take their opinions on the matter, fold them until... Mind you, I won't buy anything that doesn't come with physical media or the ability to burn the same explicitly to make it hard for the seller to try to change the terms later on.

comment Is overclocking legal?
Sony also has a pressing desire to control how you play on their network, and they'll try to use the various IP laws that apply to software to manage that, but they still have no traction on matters of hardware. A sale is a sale, and once they've sold it they have no further rights in the matter.

It's your property, man! You can shoot it, drown it in genuine maple syrup, try to jamb it into the socket backwards, or anything else you care to do. You own it. The folks you bought it from do not own it. They can take their opinions on the matter, fold them until they are all corners, and stick them someone uncomfortable.

comment emacsclient: create a frame if a frame does not exist
When I do man emacsclient it doesn't tell me about a -c option. Do you know what versions exhibit this behavior?

comment What are the pros and cons of using ErgoEmacs?
Basic things like "save" and "undo" and "cancel command" etc etc are rarely customized. I've never had trouble with a colleague's emacs, but the basics are always where I expect them to be.

comment Can a laptop run on a different brand charger?
I ran a Compaq off the transformer from a much older model (like 10 years) from the same manufacturer for almost two years. Output voltage and current matched so away we went.

comment Laptop ethernet port blinks once when plugging in power
I've seen the blink-on-powerup behavior of a variety of devices. I've never watched the ports on a laptop closely enough to report if it does or does not do what you describe, but it makes a certain kind of sense so it might be what's going on.

comment For complicated mathematic calculations, are extra threads or high-speed disk access more important?
The upshot is my experience was that fast IO systems were more important than of 20% faster CPU.

comment For complicated mathematic calculations, are extra threads or high-speed disk access more important?
I'm going to partially disagree by needed huge files to get an advantage from a fast disk. Over the last fifteen years I've worked with a series of nuclear and particle physics analysis engines and Monte Carlos; and while these sifted moderately large piles of data the thing that the IO bound ones had in common was using a lot of separate files...like ten configuration files (includes mechanism and or multiple layers of fail over defaults), and medium sided disk-based geometry database, three log files, a checkpoint system all in addition to the largish input and output files.
