Earth's atmosphere is annoying, yes, but for huge swathes of observational science it's not a deal-breaker. Not having massive telescopes on the ground where you can fiddle with your instrumentation and take advantage of apertures

So, for sleeping I'd go for softer plugs like those made by Howard Leight for shooting (Laser Leights) or Moldex Spark Plugs. Hearing protection always talks about attenuation in terms of dB(A) (A-weighting being a sensible thing to do

This is the worst thing - they have a pretty good API and sensible terms to use it for personal use at least. Garmin by comparison is an omnishambles - no API unless you're a megacorp.

"unable to avoid existing satellites in orbit being entered into" is, in my book, worse than "we just cba"

You really can't do PTP over the internet, at least not meaningfully. Anyone who needs PTP is going to have their own grandmasters, reference sources, etc - and then a distribution network. Most telecoms applications use an ePRTC sourc

There's a dedicated device, Kardia, which does this; it's fairly low-cost and claims to be able to reliably diagnose AFib. There's also another wearable heart monitor I can't remember the name of, but I had major issues

6 is useful for non-dense high-bandwidth environments where you might need to get 10G-BASET a little further than 5e will manage, but 6 doesn't address enhanced alien crosstalk. This means in dense environments it may struggle. 6A does

There are practical issues there. Liquid helium is relatively expensive and scarce, magnetic fields from the machine by definition need to be high to get good results, and to throw more fun into the mix you need to stop external radio inter

The frustrating thing with Neo4j is that they have two modes - a fairly neutered open source version, and a ~$35k/node enterprise version, with absolutely nothing inbetween. They're apparently doing a cloudy hosted enterprise vers

This topic is also the theme of a rather good collection of essays on Singapore's politics by Cherian George - there's some available online here https://www.airconditionednation.com/

Not sure what IMUs you're using, but we've been using civilian MEMS and FOG IMUs for years now. You still can't make anything purely inertial good enough to keep position accurately enough to be a GPS replacement for more tha

Fascinating. A lot of the on-chip photonics stuff has the potential to make huge impacts on other research areas, too - but the potential for significant architectural changes in HPC and even hypervisor workloads with improvements to in-mac

Certainly a huge improvement over Slack in that it's federated. It's not quite there yet, but certainly usable today - it needs to mature a little yet.

Very old audio equipment is in a similar boat - I know archivists who are prioritizing stuff for digitization based on the number of tape head hours they think they've got left in older machines.

For some media, this is absolutely the case. Particularly films that are slightly damaged, or seriously damaged, it's well worth holding onto the material in order to wait for better techniques to become available. Case in point, this
