Re: The Raspberry Pi Foundation is an official charity
I think the trading part of the Foundation is a limited company. They may though be able to get small business rate relief.

Thanks for the tip about searching for images displayed in Chrome.
I note ElReg's article is on the first google page! ElReg must be crawled at least hourly.
On more than one occasion I've googled a subject mention in an ElReg article, and the ElReg article itself was top of the results!
This is an area I know nothing about but I can't see how you can have a negative output unless it is a comparison?
If it is a comparison, what to?
"...peak transmitter conducted output power of +10 dBm, rather than -10 dBm..."
I had a brief look at the (Section 15.255(c)(3)) link but it goes way over the top of my head.
"Each A76 has 128KB of L1 cache (64KB four-way instruction cache with four-cycle load-use latency, 64KB for data), 256 or 512KB of 1280-entry five-way L2 cache, and shares up to 4MB of L3."
I've often wondered why the L1 cache size on modern CPU's are so small. ARM3 back in 1989 had a 4K cache I'd have expected more than a 32 fold increase in nearly thirty years. Later CPU's now have two extra levels of cache and I understand a little bit about cache coherency. I'm sure there must be a good reason. Anyone know what it is?
How much slower is L2 and L3 I wonder?
"You've behaved ethically, putting long-term consumer concerns first"
If they were ethical they'd make them easier to repair and whilst they may support their obsolete products better than most, they don't support them long enough to entice me, I would call it "Mid-term consumer concerns first" at best
"They USED to invert the left & top with bottom & right to visually indicate clicked or held down. "
I've heard that being called 'Slab in' i.e. trying to visually show that the button has been pressed in. The strange thing is I sometimes find Windows does change the icon to 'Slabed in' but doesn't do the action!
Currently many companies won't talk to you even about non specific account questions without asking three or more security questions including your full address. I keep telling them that asking so many questions is I believe a breach of the law! One company even insists on the full address saying that postcode and house number is not enough adding the road name still doesn't satisfy them.
"Downvoted for being behind the times."
Maybe in your area, but around here it is still very effective. In the past year nearly everything I've offered (A dozen or more items) have been collected, mostly with little hassle. I've also picked up a few things. Last week I picked up an EPROM eraser I needed!
Quite a bit of our sales are 20-35 year old BBC/RISC OS etc kit. Just sold yesterday a BBC micro with no disc interface! I'm on the lookout for old network hubs with 10b2 (BNC) and RJ45. Network intetfaces for some early RISC OS kit are now rare but I have some old but unused 10base2 interfaces that could be used if I can track down some suitable hubs to allow connection to a modern network.
"if only the file system knew a list of all the files it has stored...."
But a database could massively speed up finding a file that I can't remember where it is.
I just did a test on an SSD drive with only 167GB of data on it, it tool over 2 minutes to search for a file.
I hope a database would be two orders of magnitude quicker.
I don't understand, surely it only needs to scan the whole disc once to create a database. Then it would update it as files are added, removed or moved. The initial scan could take quite a while but the updating should be hardly noticeable.
I must be missing something!
The Titanium was designed with RISC OS in mind.
rcomp's ARMX6 uses the iMX6
and 4Ds RapidO Ig uses an IGEPv5 motherboard
Whilst the Raspberry Pi wasn't designed with RISC OS as its sole OS. I know one of the key Broadcom BCM2835 designers was a RISC OS fan and did the initial porting of RISC OS to the Broadcom chip. Thanks Adrian!
Theoretically yes. I've certain seen copies of Arthur (RISC OS 1 by another name) and RISC OS 2 in EPROM. They only needed 2 x 500K or 1MB ROMS/EPROMS. I'm not sure if they ever made any 16bit wide 2MB EPROMS that RISC OS 3 and 4 needed.
RISC OS 5 is available in one time PROMs.
RISC OS 4 was available in FLASH using chips on a carrier PCB but as they couldn't be flashed in situ (No read/write connected on the 40 pin socket) PROMs were a cheaper/easier solution.
"Pretty much everyone got rich off the breakup of Acorn... except the community of enthusiasts and developers that had bought into and supported Acorn products for a decade or more."
Dealers also lost out. My company which specialised exclusively in the RISC OS market had just invested significantly when Acorn canned the desktop division:-(
Great news about the licensing and a very good informative article!
Car manufacturers expect their products to be in use for a much longer time and they also have the revenue stream from spare parts which can be more profitable than the initial sale.
Now if only technology companies could get involved in 'The Circular Economy' Where things are designed for longevity and repairability! www.wrap.org.uk/about-us/about/wrap-and-circular-economy
"... he is also worried about how GANs can be used maliciously. “It's part of why I chose to focus on more general image modelling rather than faces - it's a lot harder to use images of Dogball for political or unethical purposes than it is to use an image of another person.”
It won't take long for the unethical to start using this sort of technique and whilst experts may be able to detect unreal images it will become harder and harder to do so as the technique improves.
 I now try and avoid using the word 'fake' as its use by certain people means it is to me a discredited term.
IIRC years I read a suggestion that an OS could be set so that if you enter one password you'd have access to just some files with the other files hidden and have another password that would give access to everything. I wonder if any OS's have that now?
If you tried 'hiding' most files then it would be fairly easy to detect but if you only 'hide' say 10-20% it might be difficult to spot.
Yes that was the first breach, but everyone in the chain are in breach. Ignorance of the law is no defence.
If you buy any second hand storage, the first thing you should do is wipe all data and when I say wipe I mean so it can't be recovered. Remember in the UK possessing certain types of pornographic images is illegal and IIRC people have been convicted even when the courts accepted that they didn't know they had them.
I can't remember the example
Over the last four or five years https://xkcd.com/936/ has been quoted in these forums three or four times most years. Each time I've tried to remember the example password, but can't. Horse and Staple I can remember, was another of the words Door... No and what order are they?
I know if I had to use the password more often I might remember it but there are quite of few passwords I only need to use three or four times a year!
One password I use about monthly is something like sH68*452aX2 I can just about remember that. Some peoples brains seem to wired differently and can remember different things easier than other people.
I write them down physically but in an obfuscated way and don't carry the copy around.
My recommendation to friends and family is to use as a complex a password system as they find challenging but manageable.
Having throw away passwords for sites you don't worry about, but not 123456.
Capitalise say third or fourth character...
When patches are issued they normally give quite detailed information about the problem they are fixing. Why are so much details given at this stage?
Many patches I read of seem to have not yet been exploited so why give the hackers many of the details they need?
I would have thought those details would not be released for say a month, though reading this article makes me think three months would be better!
If the cat is out of the bag and the issue is being exploited already then I understand there is no point in delaying things.
Knowing the full service history of a car can be very useful. I bought a car a few years ago and the paper service history showed it had been regularly maintained but didn't mention that the cam belt had been changed when it should have been. I tried contacting the garage the previous owner had used and they were going to get back to me but never did. I crossed my fingers but a few months latter one broken cam belt and I had to write the car off.
I often do the Sunday Times 'Very Hard' Sudoku and most weeks I can work it out by reasoning, but about 30% of the time I get stuck (The on line solvers I've tried also can't solve them) I then look for an 'X' must be 'here or there'' and try that.
I do wonder if sometimes they are only solvable by brute force. This paper doesn't seem to answer that question.
Great article and good to read the correct original etymology of ARM
"the original Acorn RISC Machine (better known as the ARM chip)".
When they set up ARM PLC this was changed to "Advanced RISC Machine" though I think it has for many years been just plain ARM.
Their website I see "arm, ARM and Arm" on the same page!
I recall hearing from Acorn that when Larry Ellison visited them about the NC reference design they showed him the NEWSPad he was impressed and he wanted to take one back to the states, when they said they couldn't give him one he replied but I might buy the company! They then explained that they only had two prototypes.
I wonder why is Blue is associated with Intelligence?
https://www.colorpsychology.org/blue/ tells me:
"Dark blue is the shade that is associated with intelligence and lack of emotion. Blue is an almost universally liked color. It's positive aspects are that it is a calming and safe color. It can lower the heart rate, improve mental clarity and inspire creativity."
For me an Intelligent blue would be bright, mid to light (Electric blue?)
Welcome back Alistair you were missed!
