mintyc··on 5G and Shannon’s Law
5G access (non mobile) deliberately supports 'non-terrestrial networks' of which satellites, floating balloons, repeaters on planes etc are part.

Seamless access/mobility and accessibility to maritime, airline, remote satellite phones etc is one of the ways 5G is hoping to sell 'access anywhere' and diversify from just mobile.

Most NTN access is via a terrestrial satellite basestation acting as a gateway into the mobile networks.

I think one day the communication 'transport' will be a worldwide mesh and operator profitability will be solely about business services on top of that.

Already seeing that to some extent with multiple operators sharing towers, radio front haul and spectrum. At the moment its early days of course.

Hmmm, It will. If 800MHz bandwidth is considered UWB

Think video delivery kiosk - I'd like to rent a movie please or I'd like today's daily news videos/VR. Downloaded in 3 secs from a vending machine?

mintyc··on Can 1/3 and 1/3 = 2/6? It seemed so
The and operation could be logical so the result of anding with one self is a mop
mintyc··on The EARN IT act is an attack on end-to-end encryption
Such a shame that this conversation is always so one sided because the 'other' side is not vocal or portrayed clearly in the media.

There is a controlled middle ground where the alternative to end to end encryption isn't a full surveillance state but gives safety and protection to society at the expense of trusting the other side with some of our information.

The majority?? of people want govts/intelligence to monitor, detect and pre-emptively manage: Terrorism plots Paedophiles Large scale criminals - drugs, human trafficking etc. Kidnapping Lost person location Rescue coordination

If that cannot be done without viewing content (and I'm not sure that statement is true) then personally I'm ok to trade some of my theoretical privacy for the security. Let's face it, how likely is it that the other side would be interested in my cat video content? But also don't be fooled that encrypted content means your privacy is secure. Just knowing when and to whom messages are sent is a powerful tool already and not something easily protected. App providers already use this in surveillance capitalism used by the likes of Facebook, Google etc.

mintyc··on Blake3 is 10 times faster than SHA-2
Do the runtime tests decouple from I/O times e.g. file and memory caching aren't affecting the results?

Surprised because I'd expect a big file like that to be I/o bound in practice

mintyc··on UK Government Selects OpenAPI v3
One of the criticisms of OpenAPI is the verbosity of the schema definition.

I've seen a couple of meta generator projects that generate OpenAPI specs from a meta description.

Is anything being done 'officially' to provide an abbreviated form for simpler use cases?

mintyc··on The ReMarkable Tablet: A Review
Any support for Microsoft office apps (even if via third party)? docx, pptx and xlsx?
mintyc··on Show HN: PowerPoint slide builder with handwriting
How different is this from the Nebo technology?

Sounded great but in practice was too fiddly.

Why not allow scanned documents to be OCR'ed to diagram + text. Thats the killer app!!!

mintyc··on TimescaleDB vs. InfluxDB: built differently for time-series data
Nice article but is it deliberate that you don't mention getting data into the database (line protocol or similar) or analysing the results and displaying them.

Input = use postGres Output = Grafana has a postGres data source which I assume works and mention in timescales b's issues of a Grafana query helper.

Also lack of analysis, consolidation (continuous queries) and retention policies.

I am however intrigued as it does seem to hit my sweet spot of 100's of servers each with 5 to 10 different series of 10 metrics each, every 10 sec.

Database size might be an issue, as would the complexity of deployment (a big win for Prometheus rather than influxdb though).

Final thoughts Can't help feeling this looks like a few input scripts running on postGres rather than a system solution for metrics and annotations.
