I wrote a post about writing on Substack on my (tech-focused) Substack a few weeks ago [1]. TLDR it's helped cure my procrastination. Two further observations: - The fact that it is a newsletter service and articles land in people&#x27

Fair comment. I think it's fair to say though it was intended to be a move away from the main PC microprocessor line (which you can argue traced a path through 8080 to 8086 and beyond ) and ultimately replace it at the high end - so in

Indeed. I suspect the 'x86 always' mindset though led to the expensive failure in mobile - a huge miss. Easy to see this in hindsight though.

Probably iAPX 432 would be the third.

My first job in 1984 included 'selling' System/36s - I say 'selling' in inverted commas as I don't think we actually sold a single machine - the other part was selling PC/XTs which was much easier. Also cu

So not everyone, even in your chosen subset of the market.

I personally wouldn't say 30/70 = 42% is niche but accept that the term is up for debate.

Today not 'everyone' is using x86 - by a long margin - so it's a bit of a stretch to say that in a hypothetical alternative history an architecture that failed in the market would be utterly dominant.

You think Itanium was entirely successful then? My point is that it doesn't matter how good the architecture is or if a few firms follow you - you need it to be successful in the market. If you think Itanium was a cunning plan to take

> Had it not been the case, and everyone would be using Itanium no matter what. That's quite a strong statement.

The comment specified premium notebooks not overall market share.

You think Itanium was entirely successful? Really? Plus I think you've overlooked AMD if you think they killed off all the competition.

Largely agree. I'd be astonished of they don't have high performance RISC-V designs under development. Problem is that the endpoint is much less attractive (for them) than where they are now and the transition will be very, very m

What do you mean by 'RISC-V + full featured x86 option'?

I do and I'm giving them credit that they won't make the same mistakes again with a product that fails.

> That's a niche market even compared to premium notebooks running Windows. Do you have any evidence for this assertion?

I forgot to add that there is the risk of 'Osborning'[1] x86 on day 1 of announcing a move to a new architecture as they effectively declare it a 'legacy' product. [1] https://en.wikipedia.org/wiki/O

Lots of comment here about Intel adopting RISC-V or Arm and what this means for x86. I think it's worth considering the commercial issues from Intel's (and AMD's) perspective. Firstly, adopting Arm would mean giving their ble

Interesting piece but it's not clear to me whether there would be sufficient market demand to re-use a large portion of old datacenter hard drives - who will be buying these?

On the other side of the pond there is also Clarence Hatry https://en.wikipedia.org/wiki/Clarence_Hatry Economist John Kenneth Galbraith described Hatry as "one of those curiously un-English figures with whom the

The main thing I took away from this is how hard some things can seem to someone who has a casual acquaintance with the topic. This seems to be particularly true with regard to some acts of memorisation. Lots of classical musicians can play

In general you're absolutely right but there are some parts of the City where there is some activity over the weekend. For example, the area around St Paul's and Cheapside usually have quite a few shops open and it's quite a

To add a little colour to this. The resident population of the city is less than 10k - I’d guess around 3-4k in one development the Barbican Centre - but 500k work there. 10k is about one tenth of the population per Member of Parliament in

Thanks! The version in the article is based on Cocke's own comments but I'll add a note to clarify.

From memory I think Cocke lectured at Berkeley (and maybe at Stanford too?)

Absolutely. The familiarity makes it hard to appreciate the novelty. I've looked at the architecture of some of IBM's minis of the era (and some of the more ambitions microprocessors - eg iAPX432) and they just look so strange in

There is a funny quote from David Patterson in his Oral History > There was the 801 project was secretive. There is something called the 801, “What is it?” It was very hard to know even what they were doing. It was supposed to be very ex

by klelatti 4y ago
Rereading this again I think I may have omitted one interesting point. That the 801 was, I think, one of the first computers with a split L1 cache. Will add a footnote in the absence of evidence to the contrary!

Funnily enough, I worked for IBM marketing (my first job, for a short while) in 1984. One of our jobs was to demo System/36 - one of IBM's minis - which might have been replaced by an 801 system had they taken it up. One of my col
