Back in the 80s, as the home computer revolution got going, computers were typically wired up to small, cheap, portable TVs as a display device. These TVs used shadow masks, and the computer video output was typically modulated to a TV sign

There are exceptions - here in the UK we have the RI: https://www.rigb.org/ The Christmas lectures are probably the most famous thing they do, and these have definitely moved in a more 'child' focussed direction.

They are vitamin C to the mixture, which is actually what is developing the film. There's a commercial developer (Xtol) made by Kodak which is I believe vitamin C based, and it's a very good developer. It would be interesting to k

>so how do you get a privately owned train car and get it to the tracks or etc? I think you wait in a remote bit of Nevada for a train to pass, and trigger a rock fall which causes the driver to slam on the brakes and bring the train to

Yeah, with those early machines it was inevitably about lookup tables, and producing the illusion of doing work which was otherwise impossible in the number of cpu cycles you had available. I did lots of this sort of thing for the C64, wher

This situation happens with plenty of compilers for plenty of languages. It's just software after all, we don't expect any software to be perfect, so why expect compilers to be perfect? As for deprecating old C++, yes, I can see t

And yes, people being able to use your code for whatever they want is absolutely more open than having restrictions on how/who gets to use it. One other model that can also work well is to dual license as GPL + commercial, so people wh

The problem as I see it is that LLMs behave like bratty teenagers, believing any old rubbish they are told or read. However, their voice is that of a friendly and well meaning adult. If their voice was more in line with their 'age&#x27

I was involved in writing ATC software in the 90s for a European country (the FATMI system for Finland), and they were definitely using paper strips at the time, and I believe the design did not change this. I wasn't involved in the fl

Generally speaking, the db scale is very useful for many practical situations, and this is overlooked in this critique. As have been pointed out, it's just a power ratio on a logarithmic scale, but this has many benefits, the main one

If you look at professional distributed audio systems (Dante, AES67 etc) you'll find that they all require PTP support on the hardware to achieve the required timing accuracy, so yes, you need <1ms to get to the point of being consi

The problem is that electrolytic capacitors can leak, even if not used. So, you can store a perfectly good computer and retrieve a ruined motherboard a number of years later. SMD capacitors are bad for this, the MZ80K predates all of that t

Sounds like you are either very unlucky, or have a useage pattern (or install problem) that is triggering issues. I'd definitely try and work out why they failed before pulling the trigger on another machine, no matter what the make, u

Here in europe we have Miele who make various white goods, and their washing machines are designed to actually last, rather than fail once the guarantee has run out. I think they plan for 20+ years lifetime. Our one is getting on for 18 yea

The question is about classical (newtonian) physics, which is a mathematical model, rather than the real world. The question is asking when is there non-determinism in the newton mathematical model. In the model, you have perfect spheres...

There's also the confusion as to whether people mean 'Greater London' or 'The City of London'. For the centre of the City, i've generally thought that Leadenhall Market is the centre, given it is built on the o

I can certainly relate to this experience. I remember when it was introduced, I was very wary of getting too much 'auto' into the codebase, certainly as the team could be a bit 'gung-ho' adopting stuff just because it wa

Let's consider the original list. It starts with DSLs. Are we saying that using SQL 'almost never works'? Shader languages? BPF? If I squint a bit i'd say that all the inference engines are either DSLs or APIs which wrap

It's a bad example. Lots of finance firms use AI to manage their financial affairs - go and investigate what is currently considered state of the art for trading algorithms. Now if you substituted something safety critical instead, say

Sounds like CS is not for them, and they find something else to do which is more applicable to their skills and interest. This is good. I don't think you should see a high drop out rate from a course as necessarily indicating a problem

Agreed, there needs to be trust, and how this used to work was that the photographer would gain a reputation for their accurate portrayal and would be picked up by an agency (e.g. magnum). They would supply the picture editors for the newsp

The problem is broader than this. There is a tradition of using photography to record real world events (photojournalism) which has been quite broadly adopted within our cultures - we believe a photograph as reflecting events that have happ

You mean, would it be possible to oversample the algorithm, run it effectively at a much higher sample rate and reduce the audibility of the aliases? Yes, it'll definitely help, but no, it's not possible to eliminate this effect,

On the subject of the DAC used, and why it was 'only' 12 bit. I believe the instrument actually runs all of the voices through a single DAC, so it is basically 16x oversampled, and the voices are held by a sample and hold circuit

There was mention of the sound becoming 'dull' at the higher octaves. This is not a limitation of the DAC as was suggested, but caused by the phase modulation algorithm aliasing badly at the top of the range. Basically the modulat

Yeah, if resolution is your thing, then you have unfortunately little option without spending proper money for medium format digital. It's worth it though, if you find yourself with the budget for a phase one or a fuji system!
