Infinite Improbability

I presume the caffeine is best administered as a fresh cup of really hot tea.

Have we reached the point yet where over-reliance on LLMs has become a bigger waste of terawatt hours than bitcoin mining?

Scientists trace tiny moonquakes to Apollo 17 lander – left over from 1972

Re: "craters at the Moon's south pole"

Apparently the Apollo 17 service module did actually carry a ground penetrating radar.

There’s one in South Lanarkshire, Scotland, which probably doesn’t get so hot if that’s more to your liking.

Although as it’s a large industrial estate, probably not!

Re: Booting DOS?

Interestingly the NEC V20 could emulate an 8080 in hardware, as well as being a slightly enhanced 8088. In theory it could run CP/M programs natively, as CP/M was written for the 8080, although in practice after the Z80 came out later versions of CP/M and its applications started to use the Z80 extensions to the 8080 instruction set, which the V20 didn’t have.

Bombshell biography: Fearing nuclear war, Musk blocked Starlink to stymie Ukraine attack on Russia

Simon Harris

Re: The report is not completely accurate

In the ideal case you might expect your drones to have fall-back modes if one method of communication is blocked.

I wonder if the case here is that rather than being conventional military equipment, they might be a quick and dirty lash-up using off-the-shelf commercial equipment without all the backups to see if they can get it done on the cheap to rapidly fill a hole in their arsenal.

WFH mandates bad for staff morale and stunt innovation

Simon Harris

Re: Some people work better WFH

I find it depends what I’m doing - if I want to motor through something, WFH can let me get on without as many interruptions as when I’m in the office.

On the other hand, working in the office reminds me that the people I promised some work for still exist and that I should actually do something for them instead of just the other projects that are more interesting.

Simon Harris

“Bad for staff morale and stunt innovation”

Very true - I think up my most innovative stunts while I’m in the office.

Metaverse? Apple thinks $3,500 AR ski goggles are the betterverse

Simon Harris

A bit over 20 years ago I started using Minolta SLR cameras, followed by DSLRs. My current camera from Sony (which has a compatible lens system) replaced the optical viewfinder with an electronic one. While being able to overlay graphics into the eyepiece is useful, it did take a bit of getting used to its electronic version of reality, and I still like the purity of my earlier cameras’ optical systems.

Simon Harris

I’m normally fine with any mode of transport, but the day we got an Oculus at work I spent rather too long playing with the demos and felt really sick on the bus home.

Admittedly it was a first generation device so the resolution was pretty low and it was quite laggy.

Simon Harris

Re: No additional computer required

We’re looking at applications right now that present virtual cutting guides and CT/MRI imaging overlaid directly onto a patient’s anatomy during surgery.

Simon Harris

I don’t know how easy it is to take off and put on Apple’s ski mask, but in such a situation HoloLens’s flip-up/down type screen might be preferable to give a clear view of your surroundings if you need to be aware of hazards while moving around on the job.

Re: 8080 and 8086

That’s the one!

Simon Harris

Re: 8080 and 8086

I remember the 68000 did the same thing. As well as the standard clock signal there was a slow clock output at 1/10 the CPU clock speed, typically 0.8MHz for an 8MHz CPU, which was used to feed the E input of 6800 family IO devices as Motorola were a bit slow getting 68000 IO devices out. If I remember correctly, there were a few 68000 opcodes specifically designed to access 8 bit 6800 family devices that only used half the data bus.

Simon Harris

Re: 8080 and 8086

Interestingly NECs V20/V30 drop in replacement for the 8088/8086, as well as slightly enhancing the 8086 instruction set also included an 8080 mode to run 8080 code natively.

Encoded 'alien message' will reach Earth today, but relax: It's just a drill

Just a drill

But what if the aliens attempt to contact us at the exact same moment with a vital message for the planet and we ignore it because we thought it was just part of the drill?

Sci-fi author 'writes' 97 AI-generated tales in nine months

Simon Harris

Re: each hour’s earnings is about $2.95.

You have a good point - I was trying to find out about the economics of self publishing, and came across an article suggesting many authors make more from talking about what they’re writing about than they do actually writing about it, and the books are more a way-in to doing the talks.

Simon Harris

“Impressive returns”, or not.

Running the numbers, if I’ve understood it correctly:

97 ‘books’, each of which takes 6-8 hours to write (call it 7) means 679 hours of work.

$2000 income from that means each hour’s earnings is about $2.95.

At that productivity rate I might question whether it’s actually worth it!

Large language models' surprise emergent behavior written off as 'a mirage'

Simon Harris

That, detective, is the right question.

It seems that the only real intelligence in LLM AI comes from the user knowing how to prompt it to give the answer you want. Everything after that is just a souped up word association game.

Re: AI, AI, AI!

I think there are some AI (or rather ‘applied statistics’, I don’t believe there is any actual intelligence) that are yielding good results in some fields, and wouldn’t dismiss it all - for example the pancreatic cancer finding AI.

But that I think is the problem - the more reliable AIs are trained on a limited dataset set specific to the problem. When you have a very large language model of everything and have something that can answer general questions on anything, I think the noise in the system is going to make it unreliable.

Maybe what we need instead of general AI are multiple independent AIs trained for specific tasks - e.g. software development assistants trained on good software, medical assistants trained on medical sources, etc. without them also being trained on the complete works of Shakespeare, all the nonsense on Reddit, etc. so what they produce is focussed on their ‘expertise’ without the noise of all the other stuff. Yes, it probably means they will have more limited conversational abilities and users will have to think more in how they query them, but I’d rather that if it ‘knows its stuff’ rather than giving plausible but wrong answers some of the time.

Dell reneges on remote work promise, tells staff to wear pants at least 3 days a week

Simon Harris

Re: wear pants

Crosses Brisbane off the places to visit list - obviously the food is a bit dodgy there!

Simon Harris

Re: It's not for everyone...

Sure not everyone can, not everyone wants to (I prefer to go in to work).

But talking about Dell, yes they produce physical products, but many of their production lines are outsourced to Asia, with some in Europe and South America too. Not everyone involved in the process of creating a physical product will actually need to be there to actually make the thing.

DEF CON to set thousands of hackers loose on LLMs

Simon Harris

Re: Better than hackers for red teaming an LLM

If, as other articles in this esteemed journal suggest, ChatGPT had mostly been taught using works of science fiction, possibly a bunch of hackers might be more familiar with the source material than academic linguistic professors.

Not suggesting of course that we’re all a bunch of nerds who prefer a rollicking space opera to the complete works of Jane Austen!

OpenAI's ChatGPT may face a copyright quagmire after 'memorizing' these books

Simon Harris

Re: Stop anthropomorphizing computers. They hate that.

If it read everything known to humankind only once (and there were no quotations of other works within those, which excludes a lot of works) then it might be that it doesn’t have an internal representation of any one work.

However, if it has had the same document as input multiple times (e.g. it’s crawled the web and found multiple copies, or multiple copies of extracts) or there is something that is often quoted in other works, wouldn’t the model parameters be biased towards reproducing sequences found in those works?

Could that reinforcement then be considered ‘memorising’?

Here's how the data we feed AI determines the results

Simon Harris

Suspension of disbelief.

When watching a movie (particularly if it’s a historical drama where there are known facts) and they get something very wrong about something I have a particular interest in, my suspension of disbelief vanishes as it sets me wondering what else they’ve got wrong in subjects I don’t know so much about.

I get a similar feeling with ChatGPT - I’ve seen enough examples of things I know about that it’s got wrong that I have trouble believing anything it comes out with.

Ok, so it may be ok to use it as a springboard for ideas, but I wouldn’t trust it with facts.

Or a companion probe that flies alongside whose one job is to squirt a bit of WD40 at the main probe when necessary.

Simon Harris

Re: I often wonder...

If you’ve got a giant rocket to get you there faster, does it make the orbit insertion that much more demanding when you arrive?

Is there a tradeoff that says you can’t go that fast because for the size of the probe it makes the orbital insertion burn infeasible?

“The only washers I buy don't contain a computer”

I’d be surprised if they don’t even contain microcontrollers, which still count as computers in my opinion. Certainly you can buy replacement microcontroller modules for their laundromat versions.

ChatGPT creates mostly insecure code, but won't tell you unless you ask

Simon Harris

Re: This is totally expected - it doesn't know what you're trying to do

I do actually think that ChatGPT might be beneficial, not because it produces (or doesn’t produce) any reasonable code, but that the ‘conversation’ you have with it along the way, correcting it and providing more information, might clarify in your own mind how to solve a particular problem.

Simon Harris

“down to the training data”

With current AI generations, as I understand it, the training data was frozen at about 3 years ago.

However, if future generations are continually learning, how ring-fenced will the training data be, and how easy would it be to deliberately introduce extra vulnerabilities into AI generated code by poisoning the training data by posting multiple copies of intentionally vulnerable code and associated keywords?

Simon Harris

Re: What a future

“and ideally, we used to write and unit test our own code”

I thought the ideal was that someone else would write the unit tests based on the specification and interface of the unit. That way the test writer is less likely to make the same assumptions as the unit writer and more likely to pick up obscure fault conditions.

Firmware is on shaky ground – let's see what it's made of

Simon Harris

Firmware used to have a consumer market.

I remember back in the late 70s/early 80s RAM was one of the more expensive components in a computer (more so than ROM), and backing storage was slow or expensive, so various computers were sold back then with the ability for the end user to buy extra firmware either in the form of a ROM to plug into the motherboard (e.g. the various word processors, spreadsheets, graphics extension ROMs for the BBC Micro), or in the form of cartridges, so whole applications were there instantly and didn’t eat valuable RAM.

I say ‘buy’, but probably more likely buy a blank EPROM, and borrow someone else’s firmware and a EPROM programmer.

Plagiarism-sniffing Turnitin tries to find AI writing by students – with mixed grades

Simon Harris

Re: Fail

I will insist on nothing less than illuminated manuscript from my students, to include humorous satire. I will, of course, take care not to lick my fingers while turning the pages.

Simon Harris


“the features now integrated into its existing anti-plagiarism products can detect AI-generated text with "98 percent confidence" – but has failed to provide any evidence of this.”

As someone who will soon be receiving a pile of student dissertations in his inbox to mark (which, incidentally, are screened by TurnItIn), if such a statement appeared in their dissertations without supporting evidence, that would be a fail from me.

Can ChatGPT bash together some data-stealing code? With the right prompts, sure

Simon Harris

Easily fooled

I saw another article yesterday about ChatGPT being asked to generate Windows licence keys (which it did with a low success rate).

Ask it directly and it tells you it’s illegal and you should pay for it (actually as the demo was for Windows 95, it said to buy a newer one). Reformulate the question and it has a go.

If it’s so easy to hoodwink ChatGPT into doing things it’s specifically not supposed to do, I have an inheritance from a Nigerian Prince it might be interested in.
