Ooh, that's an interesting project, definitely lots there for me to learn about. Thanks!

Yeah, I had an LSI-11/23 when I was a student, with dual 8 inch drives and a Fujitsu drive (not an Eagle, it was 160Mb if I remember). This was all cobbled together equipment, but lots of fun trying to get it to work. My bootstrap code

Lovely work - i'm wondering if you now have enough info to build a VHDL model from this? It would be very cool to run an emulation on an FPGA. My interest in these instruments goes back a long way - I reverse engineered my DX7 to buil

Yeah, I think you're right, keeping people motivated vs maximising productivity is key to get right. There's also the angle of keeping your eye in with other languages, e.g learning or keeping your python skills up to date if you

Agreed. I remember reading his autobiography back in 2005 or so, and thinking what a weird self-centred individual he was. I certainly don't agree with his politics. However, I think there's no doubt that Dyson make great vacuum c

We have a 100 year old grand piano, and our piano tech commented that the lid had previously been removed. He knew this because on this brand of piano, the screws would have been aligned horizontally when they left the factory, and the ones

Indeed. As a driver in the UK, I use the horn so rarely that i've forgotten how to make it work when I need it.

A quick question for you peeps working in larger organisations with 1:1s (i've been out of that game for a number of years). How have you adapted your 1:1s for remote working? It's always felt to me that moving out of the usual wo

I think the point is that this theory was first proposed in the 20th century, and given the structures were designed and built something like 1000 years earlier, it is at this point speculation, and there is no evidence to support the asser

I would be interested to know how Microsoft is justifying this - what does the Edge browser do that others don't? I presume they can't argue the old 'it's an integral part of the OS' type stuff following the previou

I'm guessing late 50s onwards, as stereo was introduced, what, 1958? I'm a fan of the quad stuff from that era, ESL57s and Quad IIs as well as Tannoy speakers. I imagine you're more US centric in your appreciation, but it was

It's an interesting subject, and i've some experience of photographic preservation having printed in darkrooms for 20 years or so. When considering archiving old photographs, there's quite a bit of difference between colour a

Yeah! I went ZX-81 to C64, then Amiga, but the MSX machines were always interesting, especially the ones with built in MIDI interfaces. This was such a creative period for computer design, primitive though it appears from our modern perspec

The international banking system is coordinated by the SWIFT network, and all inter-bank messages are encoded in EBCDIC. If you transfer money between countries, or get statements from a broker, chances are it lived in EBCDIC at one point i

Indeed, I don't think the UK government has any problem hacking phones if they believe this is required, but it's likely to involve disclosure to the courts, and hence in some way be accountable. It's therefore easier to get

I think that's taking things a little too far. How I see it, Darrell Huff was a writer, not an academic, and he wrote a number of books over the years about all sorts of stuff. I presume he got a bee in his bonnet about statistics at s

Agreed. It's wrong to think though that the way that digital photos are taken would imply very large costs for film. From experience, you take shots in a different way, and are forced to be more contemplative with large format, and it&

I think you're missing the point. floating point isn't madness, but people thinking it represents the real numbers without stopping to consider how it works is madness. For example, just consider the number of bugs that come down

The other side of the coin though is that when you are too close to your code, you can't see some of the refactoring patterns which will simplify it. Fresh eyes bring this to the party. So as ever, a mix of approaches, competencies and

It's not clear from the article, but I think what they are doing is delaying part of the frequency range of a signal. All this talk of negative delays is really confusing, it's just that they are delaying frequencies outside the r

I remember i860 accelerator cards being used with Fortran compilers, not really sure if this went anywhere, it's all a bit hazy exactly what happened, but the i860 was VLIW, so the compiler tech required for Itanium was already being e

A good book to read on the subject is Jane Jacob's The Death and Life of Great American Cities. It's 60 years old now, and is concentrating on cities rather than towns, but you can see the points she is making play out in scenes l

I think this is the key. My understanding is the FMADD on arm64 does what the spec says it should do, so there's nothing broken. Next up though is whether fused multiply add is part of the IEEE floating point standards, and whether the

Well that's an amazing instrument, i presume it's straight strung? I didn't see any clear images of the inside of the piano, how the harp was constructed etc. For the rest of us who want to play around with piano lengths, the

You'll only hear one side of the coin. I would also want to hear from people who understand AI/ML and have decided not to use it in an application domain. That's probably the most valuable info, knowing when not to use a to

It's true that interruptions are a source of significant cost for programmers, but the other side of the coin is that talking through problems and design decisions with other programmers can generate a massive gain in productivity. Let

Back in '87, we're talking 386 territory for cutting edge compute, so I think we were limited to 25Mhz. As has been pointed out, those machines were expensive. Pulling out an old PC World magazine from '89 I see that a 386&#x
