Comment Re:QWERTY. (Score 1) 165

It *is* really awkward - I agree, and especially it's hard to accurately distinguish left-arrow from down-arrow. But if you have hands in typing position (eg for a trackpoint-style keyboard), then the minimal movement of the hands is to use RH pinky. It's the finger I probalby use most, for shift, and the 4 arrow keys.
[Btw, none of my keyboards, either desktop or laptop, have a numeric keypad]

Comment Why not use a bioreactor? (Score 2) 214

If we can take grain + yeast and get beer, then why can't we design a yeast-variant that produces milk? After all, grass and wheat are very similar.
Of course we might not get all the complex proteins and enzymes required to make good cheese - but it should be possible to get a perfectly decent product for putting in coffee, making ice-cream, and pouring over cereal. A cow is a terribly inefficient way to convert grass into milk - we should be able to do better.

Comment Re:Android / dual-boot / X-windows? (Score 1) 112

I see why it's hard to run another distro natively. But why not run a small Linux inside a VM, and connect to it fullscreen with VNC or X? That would be almost as good, and shouldn't be that hard to do - the compilers already exist for the apps, and both VNC client and X11 client (technically, server) programs exist already.
If I were Samsung, I think I'd fund such a porting effort out of pique!

Is there any chance to put another OS on the iPad?
It would be a great way to get an Android tablet with a proper 4:3 display and good speakers. Or why not run X11 on it, and LOCAL applications (or VNC and a local install of android or a regular Linux).

Also, once jailbroken, is there a way to make the Music/Video/Photo apps recognise files that were loaded on using SSH rather than iTunes?

Comment Re:Windows Application license time-sharing? (Score 1) 113

This is the question. What I'm trying to do is arrange the "5 MS machines in a corner, walk over there and take your turn" approach, but without the walking. The company would generally have zero users making use of MSO; it just needs to know that all 100 of them could, if they had to, have occasional access. The Windows machine could be a single-user box, running a single shared "public" account.

Otherwise, what would it take to have a system that could script MS Office, to provide, say, a web-service that could take in an awkward powerpoint, and spit out a PDF, in a compatible way?

Comment Windows Application license time-sharing? (Score 2) 113

What I'd like to know is whether we can have a way to time-share Windows applications. Consider an office of 100 people. At the moment, they all of MS Office installed, just in case they get an attachment that LibreOffice can't handle. That's 100 copies of the MSO license.

We'd like to move them to Linux, and LO, but still need that MSO capability just occasionally. So the obvious way is to set up 100 free desktops, and put 5 Windows+MSO machines in the corner, people can then walk over, queue up, and use the MSO machines if they really must. Result: only pay MS for 5 licenses, and start escaping lock-in.

But that's really ugly. Is there any elegant way to do this seamlessly for the end user, with VNC or similar? We need to ensure that 100 people can all (potentially) access MSO in their own environmnent (own PC, own view of the fileshare, if possible, own preferences), but with some sort of queuing system that shares out the access.

I'm aware of the ugliness if 6 people need MSO at the same time, and that this might not work well for video, or advanced powerpoint. But otherwise, how might it be done? (And given that MS might not *like* it, how do we stay legally covered. IMHO, this is perfectly fair, because MSO is only ever installed on 5 PCs, and only ever used by 5 people at a time).

Comment Re:Wait, what? (Score 1) 379

Interestingly, that's not the whole story.

In Bash, the $ sign is a unary operator that means "replace NAME by its VALUE". That's why, in Bash, assignment of variables is done without $ signs. For example:
fruit=apple; echo $fruit. It's also why the bash shell allows $ to do so many things, such as ${filename%.extn} (strip off the extension from a filename).

In PHP, $ isn't an operator, but a symbol that means "variable". This is useful for clarity, especially when there are so many keywords around, and when a variable could be auto-vivified (and shouldn't be confused with a constant, or an unknown keyword).

Also, interestingly, $1 and $2 etc are meaningful in Bash and Perl, but in PHP, they are NOT variables. They get used in SQL query parameters, but otherwise, the $ is considered literal. Eg echo "this is $1"

Perl distinguishes variable scope between scalar/array/hash. PHP allows a variable to be either (and sometimes to swap types), and considers "array" and "hash" to be basically the same thing.

 

Comment Re:F18 upgrade observations and whining (Score 1) 458

Linux fonts always have been rather a nightmare. There are really only 4 solutions:

1. Learn to live with blurry antialiased fonts. In my experience, about 80% of people actually prefer them that way. Windows defaults to "cleartype".
[Some people (like you and I) really don't like them this way, and hate the colour-fringing from sub-pixel antialiasing; we'd rather have clear and sharp letters than care about the glyphs looking different in different typefaces]

2. Go back to the old (2000-era) 75-dpi and 100-dpi fixed (non-scalable) fonts.

3. Get a very high DPI screen. (I got a 2048x1536 15" LCD panel); this makes the antialiasing work OK becasue you can't see the pixels.

4. Choose your fonts very carefully, turn on hinting, disable antialiasing below 15 pt. (You may need to change your libfreetype for one with the bytecode interpreter enabled - software patent). Personally, I use Terminus for the terminal, and 8-point Tahoma everywhere else.

To fetch the latter, first install cabextract, then:
wget http://download.microsoft.com/download/ie6sp1/finrel/6_sp1/W98NT42KMeXP/EN-US/IELPKTH.CAB &&
cabextract -F 'tahoma*ttf' IELPKTH.CAB &&
mkdir -p /usr/share/fonts/truetype/msttcorefonts/ && mv -f tahoma*ttf /usr/share/fonts/truetype/msttcorefonts/ &&
chmod 644 /usr/share/fonts/truetype/msttcorefonts/tahoma* && fc-cache -v && rm -f IELPKTH.CAB

How is that different from an ordinary server cert? I just got a cert for my own domain; that doesn't let me masquerade as a bank. If I get my browser from Mozilla, how do I know that my ISP isn't snooping? If I'm reading you correctly, you're saying that the entire HTTPS spec is a total wreck, and we'd be better off without it than a false illusion of security?

Comment Ftee Software Freedom # -1 (Score 1) 453

I'd like to suggest that online dating is an example of a cloud service, where freedom # -1 applies, namely:
  the freedom to interact with all other USERS of a social network, and portability of the communications.

One of the major problems with Internet dating now is that the market has fragmented - we need a single, global site where ALL single people can be found, and which is free and searchable. We don't want a monopoly of service providers, but we need a single common standard and interface. Otherwise, every site has the incentive to lock in its own users and to do the whole bait-and-switch thing (aka "free to join, pay to reply").

Incidentally, I run one such site, and I posed this very problem to RMS.... his response was very insightful (though not very helpful): he said "not every social problem can be fixed with a software license".

Comment First class camera (Score 1) 453

I want a really good camera (at least 12 Mpx, and a decent lens). Something that will obsolete my normal $250 digital camera at least in good lighting.
[I know of the Samsung Galaxy Camera; sadly it doesn't actually get good photos - the sensor is very very noisy]

Also, a sunlight-readable display, and a microphone which can be used to record musical performances credibly.

Lastly, *please* can we have a 4:3 Android tablet, with all 4 buttons (back, home, menu and search) as hardware ones. Enough with the silly short-screens.
