Just intercept the read and write calls! On linux you can just use 'strace $prog'; try it on a minimsal program that reads and writes a file. For a custom approach, this can be done with a library (using LD_PRELOAD). Plenty of art

Worth noting that the framebuffer works really well on the Raspberry Pi; you can switch between console and X, all while using the framebuffer. It's even happy switching between bit depths (using 'fbset') at the same time. If

Shades (a commercial successful MUD that ran on British Telecom from the mid 80's) happy ran with 64 users on a Z80 with 256K RAM, 2Mb RAM disk and 10Mb HDD. It's actually still running (telnet://games.world.co.uk) thoug

It's not 9.81, it's more like 9.87 (you got the distance correct at 0.13 so I guess a typo?).

Thanks; the closest a quick search threw up was 22987/7923 = 2.9013000126 which confirms the bogosity - I was just interested to know how the bogosity was being justified.

That's pretty much it; although at higher intensities the calories per unit time is higher, the higher the intensity the more comes from short-term stores (glycogen) than from long-term (fat). The numbers suggest 60 to 70 per cent of m

Thanks for that! Great demo, and using strong UV shows the effect in spades (I'd guess in this case you wouldn't want the radioactivity, so the illumination effect from the photons is more pronounced).

The 'detox' side of it is very likely garbage (but a great way to sell); on the other hand, 5-hour bike rides without fuel will deplete your glycogen stores and there'll come a point where the differnce becomes obvious (see &

Neon bulbs require a certain voltage to strike (for small ones, several 10's of volts). Until they are struck they are very high resistance, once alight they are low resistance until the voltage drops well below the striking voltage. T

Have you compared the brightness against a new LED of the same model? My experience with many higher-power (60-100w equiv.) bulbs is that they are quite a lot dimmer after a year or two of heavy use.

Can you give us a quick run-through of the maths that led to the 2.9013 number?

As a simple demo of this, running 'gimp' as a 'guest' user allows you to take screenshots of windows owned by the user who started the session. Thus, a compromised copy of firefox on the 'guest' account could,

In both cases (on separate accounts, same computer), it said "Thank you, xx xxxx! Let's see the magic..." (I used the same user name and IP address from both). Restarting (exactly the same version) of Firefox a second time an

From my brief look at firejail, how would I do the rollback? (i.e. reset everything back to exactly how it was before the run). Also n.b. I'm not rolling any security measures of my own here - it's reliant on the kernel correctly

Interesting, thanks; I haven't seen it, looks interesting and a worthy project. I tend to prefer simple low-tech solutions though, and given the first two commands to start it are to do with fixing pulseaudio bugs and desktop integrati

Indeed, that's the approach I use to run multiple copies of Thunderbird. Using a separate account does add protection against browser exploits though (if visiting an interesting-but-risky site, the 'guest' account approach pr

I'm not familiar with Firefox Multi-account containers; do they use separate Unix accounts? (since my approach means Firefox is running as a completely diffrent user, a simple firefox compromise or bug shouldn't be able to access

For privacy, on a linux box are there any downsides to simply creating one or more extra accounts, and running Firefox in them for privacy ('DISPLAY=:0 firefox')?. I use this approach to set up firefox as I like it on a spare acco

They certainly looked very similar (as they would from that height) but the thruster firings were not at all synchronised (I thought the same thing, until I saw that).

Yes, Perialaga hosts it and I look in from time to time. Write a message on the chattrack if you make it back there!

NB 'mouser' is still in the file; not giving too much away if I say you don't seem to have logged in this millennium :)

Text search engine? (submit the query to $SEARCH_ENGINE, and display the results - or bonus points for using Gopher). Shouldn't be hard to do 1200/75 on the Pi audio, even on the stock audio output.

Your persona is almostly certainly still in there (unless you were naughty enough to get blotted). The Telecom Gold gateway was way better than the Prestel one; more gome users on the Prestel (Micronet) side though. What killed both Prestel

That'd be 'coder' to you, Sir! Sorry about the bills - I always felt bad about them.

I strongly suspect the interactive (mostly adult) services were the bulk of the bandwidth; the rest of it was relatively short, infrequent and low-bandwidth sessions like looking up phone numbers, catalogue ordering or paying the odd bill.

Block graphics and text at 1200/75 baud - say 1 million people online and all busy typing, that's 75 x 1E6 x 8 upstream so it wouldn't trouble a single 1Gb ethernet link. Downstream would be 16 times that, so 10Gb would handl
