Pong

I don't think pong consoles used microprocessors, way too expensive at the time.

I have a rather knackered old Grandstand match of the day 2000 pong type console, with 4 games.

The switches and control pots all need replacing badly. (and probably the capacitors and other bits).

The way the screen flickers as the contacts make/break randomly gives the game away that internally there's just a bunch of registers, counters, comparators and other glue logic to make it work. There is no frame buffer, the video signal is created in real time with digital logic circuits, using digitised analogue paddle signal, game select/mode switches, and horizontal/vertical video counters as input.

I think it may be stretching things a little to describe speak&spell as being microprocessor based, but I don't know much about that. I do know it's somewhat inaccurate to say it had a speech synsthesis chip in it, it used audio compression with a very low data rate.

I agree they can be hard to decipher, but the posts in this thread made sense to me, although many don't. I'm mostly too lazy.

I'm not sure why dolphins need to communicate accurate directions, but bees can so it's not out of the question. More likely they can lead others to interesting places. They're certainly able to teach each other foraging tricks. The point of the comment was that different beings (human, animal or chatbot) don't have the same reference points on which to base effective communication.

"You have assumed that, since we can't understand their communications, it must include everything."

Err, I said everything they need to communicate. We may not know much of exactly what that is, but the species are still alive so must be doing something right.

"this bot's overdue for a shutdown."

Why would you think he's a bot?

I see him as someone who sees the world around him very differently from you or me.

Communication between parties depends on them having a common understanding of the world they inhabit. That's kind of what the article is about. It's also why we can't communicate with dolphins, they are more than capable of communicating amongst themselves everything that they need to to live in their world, but that world doesn't overlap our human world.

If someone has in their head a different model of the world to yours, that doesn't mean their opinions are any less worthy, it just means the communicating with them might be more difficult.

This is why social media's creation of bubbles around people is leading to increased political polarisation, I see this as extremely dangerous.

There's a point beyond which more talking is a hindrance to progress, not a help. I used to socialise on usenet, and saw plenty of discussions there descend into insults. It's all happened before.

Allowing the unwashed masses onto the internet is ruining it. That also happened before on usenet: https://en.wikipedia.org/wiki/Eternal_September

Boffins unveil SSD-Insider++, promise ransomware detection and recovery right in your storage

I can't trust this bit >

"For recent HDDs - e.g., SMR [Shingled Magnetic Recording] drives - based on append-only magnetic media, the same idea of SSD-Insider++ can be directly applied," Lee told us."

Some testing I did on a DM-SMR drive I own indicated that large writes went directly to the shingled tracks, because they can. Only small writes and probably the start and end of large writes (i.e. not a full set of shingled tracks) go to the buffer area. So this won't work on SMR HDD's.

In any case, even with SSD's this all depends on the disk not being too full, is there enough internal overcapacity to guarantee its function?

UK's National Cyber Security Centre recommends password generation idea suggested by El Reg commenter

brainwrong

Re: Strong like this?

"On the other hand, bork.badger.bork.badger would take 10000+ centuries!"

So that would take a million years on a typical home PC.

The last article I read mentioned a tianhe supercomputer that's still 4th in the top500 list of known computers. It has over 10 million cores, lets say it's a million times more powerfull than a typical PC. Given that password cracking is an embarrassingly parallel problem, this machine may be expected to take a year. You need to consider who you are defending yourself from and what resources they may use against you, both now and in the future.

"Unless bruteforcing doesn't mean what I think it means."

You don't just build up passphrases to test from individual characters, you create a list of characters and words in order of decreasing expected probability, and combine these into candidate passphrases to test based on their probability. The word 'rhythmic' is more likely to appear in a passphrase than the letter sequence 'cmyihtrh' or 'cihtyhmr' or 'tyrcimhh' or 'yihchtrm', so it's worth testing such passphrases earlier.

For strong passphrases I would suggest 4 (or 5!) random words, with some deliberate corruption, such as mis-spelling, extra inserted characters (a couple of numerals or punctuation marks ought to be good), some random capitalisation, maybe move any word-separating characters about. You don't need much of this, but avoid obvious substitutions such as '0' for 'o' etc. You should end up with non-dictionary words which are hopefully not too difficult to remember. Stick to common punctuation marks, there are pitfalls with different character encodings.

To remember passphrases, use them, use them, USE THEM.

Or write them down, but this creates new risks.

I'm no expert BTW.

Re: Its very easy to detect ground based broadcasts

"Your first instinct is correct, why let them in? you are not required to prove you don't have a TV, just send them on their way."

Dunno, just to see if it made them stop I think. It didn't matter either way, I genuinely don't receive TV broadcasts any more so there's no risk of me being caught out.

"If they want to waste money continually sending you threatening letters then that's their own problem."

That's my general attitude, I still get fed up opening the damn things.

Re: Its very easy to detect ground based broadcasts

"given that TV detector vans exist in the UK"

No they don't. I don't think they ever have.

That was a scare tactic used until sometime in the 90's. I saw one once in 1990 on the university campus, licensing officials walked round the halls of residence knocking on doors and asking if anyone had a television, that wouldn't have been necessary if the vans were real. I happened to be out when they knocked, my TV used for my CPC464 went undiscovered. I was outside, looking at an old panel van. There were 4 ordinary tv aerials fixed to the outside on top, one on each corner. Visible inside was an assortment of 1950's era tv production equipment. No-one was in it doing anything, such as detecting tv's.

The current scare tactic is for crapita to send scary looking letters out to everyone who hasn't bought a tv licence, threatening to open an investigation, or maybe send someone round. The letters can be safely ignored (I haven't received any since i burned the last batch). Someone once did come round whilst I was in. I let them in to show them the back of my telly, where I had removed the tuner head so it was unable to receive broadcasts. She wasn't interested, or didn't understand, and asked me to turn it on to see it not receiving a signal. The letters stopped for a couple of years after that, then started again. They seem to think I'm going to reply to them each year to declare that I don't have a telly, fuck that.

Boffins chill out with new temperature measurement

Marks deducted...

"The triple point is a definition rather than a measurement: the three states of water can be calculated to exist at 0.1°C and a partial vapour pressure of 611.73 pascals – in kelvin, 273.16K."

Err, you missed a zero, it's 0.01 celcius. Everyone knows that, yet even QI got it wrong once.

And I'm pretty sure it's not calculated to be anything, the triple point of any pure substance is just whatever it happens to be, but it is fixed and easily reproducible which makes it a very good reference point.

Here's a thought:

The newton is defined in terms of the kilogram, which is a problem unit to define. Triple points don't just have a precise temperature, they also have a precise pressure. Could that be used to define the newton, and hence the kilogram?

Brit boffins GANG-RESEARCH tiny LEDs for 1Gbps network

brainwrong

"And by making each LED a subtly different colour, they can all transmit separate data streams, which means 1,000 of them packed into a square millimetre can outperform existing techniques a million times over."

Given that current LED's are not monochromatic, I think someone's being a bit optimistic there.

To answer Norm DePlume, yes you could make proper white LED's by putting lots of small differently coloured LED chips in a single package.

<RANT>

Donkeys years ago there was an article in new scientist about the invention of the gallium nitride blue LED. They mentioned that it would be possible to combine the blue with orange light to make a white LED. I thought at the time that whilst it may appear white to look at directly, the colour rendering of such a beast would be terrible. Unfortunately that's pretty much what the manufacturers did. Now we have bright LED torches that are hard to see by, stupid flashing bike lights that cause loads of glare because of the blue content, and now the world is filling up with cars with over-bright daylight running lights! I fucking hate it all!

Chaos

The weather is a chaotic system.

Even if we know the precise differential equations to simulate it, the real weather will diverge from our calculated prediction simply because we can't measure the current state of the weather perfectly. Any error in our measurement of the current weather, however tiny, will be magnified with time. Predicting weather weeks/months in advance is foolish.

Meteorologist Edward Lorenz stumbled upon this phenomenon in 1961 while running computer simulations of convection cells.

Fujitsu busts K super through 10 petaflops

brainwrong
Thumb Up

@Steve 48

Excellent idea! Slow mode or Fast mode?

The ZX81 didn't do double precision, it used a 40 bit format (documented in the excellent manual).

I don't know the flops rating of a ZX81, and I should think that the difference between adds and multiplies (done in software) would be much larger than modern hardware, which may complicate comparisons.

For a rough idea, a mandelbrot renderer I wrote in BASIC on a CPC464 (same Z80 running at similar speed, also 40 bit FP) achieved about 166 iterations per second. That was 4 adds and 4 multiplies, giving a whopping 1333 Flops!

Re-writing it in PASCAL tripled the speed, at the expense of reduced precision of 32 bit.

That was still so dreadfully slow that I re-wrote it again in Z80 assembler, bumping the precision back to 40 bit with my own routines. That ran at double the speed again, 1000 iterations/sec. Here I was able to replace a multiply by 2 with a single INC instruction, so I'll only claim 7 ops per iteration for 7 KFlops. I was still running renders up to 2 days at 320x400 resolution.

I have no idea how fast double precision could be done on a Z80, which is what is needed for a true comparison, maybe someone has done it and knows?

Aluminium

"The most a failure of the latter (bicycle) can do is ruin one's crotch or day"

That's complete bollocks, as has already been mentioned elsewhere.

Anyone using an aluminium bicycle frame is nuts, and should be forced to take physics lessons to understand why. Steel only suffers metal fatigue when it is flexed more than a minimum amount, aluminium suffers metal fatigue when flexed by *any* amount. This was found out the hard way, when early alu aircraft fell out of the skies.

Aluminium is used for aircraft because weight is critical for performance and viability. Aircraft get lots of R&D to minimise the problems of aluminium, and regular thorough examinations to pick up the majority(*) of problems that still exist.

I doubt the same could be said for most bicycle frames.

(*) not all, i remember only this year a plane had a hole rip out of the fuselage skin, above the luggage racks IIRC. I don't think anybody was sucked out and torn limb from limb.
