Modern operating systems do do memory compression as claimed by the original SoftRAM. In the case of Windows it was added in Windows 10. I wonder if it would ever have been economical, in performance terms, back in the day.

It’s a long read, but it covers the period from the original IBM through to the 386 in impressive technical detail.

The spec for data analytics doesn't list Rust. Instead it requires "excellent C++ ability". Are you actually using Rust?

It might be a bug on my side, but FYI. The last bullet point in the "Desired" section of the job spec shows as blank in my Firefox Nightly on Ubuntu.


We don't have a role for pure Rust development but I'd be interested to meet somebody with C++ plus Rust, or Python plus Rust. Maven primarily uses C++, C# and Python, but we've recently started using Rust on a couple of projects.


thanks for your reply - i noticed you reworked the job spec as well.

Would be cool to hear about your Rust project, however, I realise you might have an NDA on this.

Sounds like a great role


Because PS/2 is interrupt driven whereas USB relies on the CPU polling for events.

https://en.wikipedia.org/wiki/PS/2_port#Legacy_port_status_a...


It's mostly irrelevant. USB uses polling internally, but the polling frequency is high and an interrupt is generated on the bus side when something has happened. I have taken latency measurements on PC hardware for a serial communication situation, and USB latency was a very small part of the problem. 1-2 milliseconds typically.


It isn't irrelevant because USB packets still have to wend their way through the host stack after reception. Interrupt driven IO is always lowest latency.


There is no separate interrupt line that devices can use to interrupt the host. All USB traffic is started by the host.


Yes, but with sufficiently high polling frequency it doesn't matter very much. (It is true that each hub may add latency, as your sibling comment noted.) Regarding the "interrupt on the bus side", I may have expressed myself badly - I meant PCI(e) bus.


Transport for London did this for one week on the Tube last year - https://blog.tfl.gov.uk/2016/11/23/wifi-data-trial-understan...


It's absolutely not. Everything I've seen has been 64-bit double. If you need to, you round either intermediate or final calcs to a set precision.

I once worked on replicating a particular index, and the engine used fixed point internally. In order to get the values to match with the ones published officially, we had to emulate Excel floating point: our fixed point values wouldn't line up with theirs.
