  • Hacker News
  • That one job was to process "sensitive" intelligence intercepts and break codes, if you're not grabbed by the clickbait headline. It's a good read.
  • What's clickbaity about it? Breaking codes and using that to process intercepts (or other encrypted text) is the definition of cryptanalysis.
  • What happened to IBM?
  • They became NSC, no such company.
  • They royally screwed up by signing an exclusive deal with the back-then no-name Microsoft company. IBM created the 3 trillion behemoth that Microsoft is while killing themselves in the process.

    It's really sad but also infuriating: had IBM not fucked up and not signed Microsoft, that mediocre company that Microsoft is would have gone nowhere and we wouldn't have to suffer their turds since decades.

    P.S: in their dying breath (and I know IBM still exists), they did commit one billion dollar to Linux early on (which back then was a big deal). When we see the tens of billions of devices that now run Linux, IBM at least partially participated in Linux taking over the world. So there's that.

  • Sometime in the 90s they decided that becoming a services and consultancy provider was more important than being involved in large-scale commodity hardware or really anything else.

    Over three decades they've exited commodity hardware (x-series and thinkpads), retreated from a lot of software stuff and generally gone as hard as they can for large-scale business contracts. They seem to keep a decent amount of cutting-edge hardware research going, Power is still broadly competitive with x86 AFAICT, but the volumes have got to be pretty low these days and I half suspect that some of it is just a "Hey look at us we're still here" play rather than actually feeding into products, because services are the profit-centre.

    They're still huge and have a lot of money, and they own Redhat. But IMHO it's in a long, slow decline, and it has stepped back from the public eye and most public-facing markets.

    Context - I've worked for them in a few places. Obvs my opinons are my own, especially as I've been 'out' for over a decade at this point.

  • They had vertical integration and made bank. Then each layer got more complex as computing became mainstream, and IBM got out-competed on everyone of them by specialized companies. And then they sold them off. The only layer that remains is the most strategic: the customer relationship.

    IBM is now just a consultancy.

  • sometimes I wish I was born a few decades earlier. it would have been fun to work on things like this when they were new
  • Cold War era computing is fascinating. The scale they achieved with 1960s technology is impressive.
  • You'll want to read about SAGE

  • Wow... so many blinkenlights! Love it.

    "IBM's Fred Brooks Jr. (..)"

    Yes, that guy from "The Mythical Man-Month" fame.

  • Has anything ever been written up about the chips that the was (is) NSA fabbing?
  • Every time I read an article like this, I get depressed about all the hours of my life I've spent waiting for computers. I'm 64 now, and I've been using computers since I was 14. (Batch mode, using punched cards on an IBM 370 was the first computer I programmed, while I was in high school.)
  • One of the big features of the Harvest was the so called POPCOUNT which was supposedly added the machine at the NSA's request. (This is the number of bits in a word that are on.) I've always wondered how this might be used. Some suggest computing the Hamming distance. Others suggest some kind of statistical test like chi-squared. But are there other more algebraic solutions that can benefit from it?
  • As the article belatedly mentions, the ~40 GB automated tape library for HARVEST was the bee's knees... and possibly the inspiration for "harvest now, encrypt later".

    PS – Primary sources for the IBM 7950/HARVEST on Bitsavers, excellent as always:

  • Decrypt later, I suppose.
