dll··on Monitor your security cameras with locally processed AI
Two cameras, CPU usage is very low (NPU spikes when there’s movement). I suspect I could add more without too many problems.
dll··on Monitor your security cameras with locally processed AI
I have it running on an Orange Pi 5 with the Rockchip NPU, very impressed with that being supported and working so well for object detection.
dll··on Htmx, Rust and Shuttle: A New Rapid Prototyping Stack
You'd use the hx-delete attribute and have a server side handler that responded to that by deleting the item & returning a new list of items. You can see an example of that approach (with Rust + Actix Web) here that I'm currently working on (the partial to list todo items is in templates, and you can follow the delete link to the relevant handler in routes/todo/delete.rs):

dll··on Fire extinguished at Ukraine nuclear power plant, Europe's largest
It appears that EURDEP (European Radiological Data Exchange Platform) data isn't being shared with the public at the moment. I'm not sure if this is because of the war, this attack in particular, or if they're having problems with their infrastructure due to people like me wondering what's going on.

Their simple map (https://remap.jrc.ec.europa.eu/Simple.aspx) shows the last update as being 03/03/22 22:00 UTC, but selecting a station doesn't give any current or historic readings.

The advanced map (https://remap.jrc.ec.europa.eu/Advanced.aspx) doesn't display any data for me.

dll··on Time to run or time to walk? Your body knows the answer
I didn't follow any training plans to get up to the half marathon distance. Once I'd finished the C25K plan I decided to see what 10K felt like and it was ok... did a few of those and then tried 15K. At that point I figured I could do a half and entered one. Although I didn't follow a plan I do keep an eye on my GPS watch to see what pace I'm doing - if I'm planning a long run I'll hold back the pace from what I know I can run so I don't tire myself out.

I think training plans depend a lot on what you're wanting to do - I just wanted to complete the distance; I could probably do it faster with a proper training plan but I've found running without worrying about time (too much) to be enjoyable (and I have still got respectable results for my age).

dll··on Time to run or time to walk? Your body knows the answer
Couch to 5K (C25K) is another run/walk training program, which is very popular here in the UK. Even the NHS (https://www.nhs.uk/live-well/exercise/couch-to-5k-week-by-we...) promotes it.

I started with a C25K plan in November 2020 and ran my first half marathon in October 2021. I'm looking at marathons now, it's changed my level of fitness far more than I could imagine.

dll··on Cave-Link: Underground text communication system
I wonder how the licensing issue referenced in the Wikipedia article is handled in the UK. I imagine Ofcom will have had to approve and license these installations, or will they have made these exempt (I can't find any evidence of this)?
dll··on Cave-Link: Underground text communication system
This was used in the recent rescue in Wales [0]. I seem to recall a colleague telling me years ago (in about 2000) that he got stuck in a cave once (somewhere in South Wales I think) due to unexpected rain causing flooding and there was a phone available that could be used to request rescue (or to tell people you were going to sit it out).

dll··on In 1783, an English rector predicted black holes using classical mechanics
It's quite often used this way in Wales. It makes a lot more sense when you realise that borrow and lend both translate to "benthyg" in Welsh.
dll··on Do political stickers work? (2020)
In Wales you can't go anywhere without seeing Yes Cymru stickers, to the point that unionist politicians complain about them; I'd say they're working here.
dll··on Universal basic income to be tested in Wales
There's some interesting post election anaylsis that picks up on this (in Wales at least). There's a view [0][1] that while results are bad for Plaid, they're getting a lot of what they want, and shifting the window on the most important issue (independence). In addition to UBI, it's interesting that Welsh Labour have started the push for "home rule" [2], something that is likely to win them a lot more votes from traditional Plaid Cymru supporters.

dll··on Virgin Orbit has succeeded in putting its first satellites in space
One of the satellites launched was for amateur radio; at the time of this comment it doesn't look like anybody's heard anything from it:

dll··on Wide-Band WebSDR – Shortwave Radio on the Internet
I joined a university club to do the test even though I'm not a student. It might be worth seeing if a local university has a club that would be happy to help you?
dll··on [dead]
Agree. Clicked on a couple of books and these are clearly pirated.
dll··on Has There Been a Nuclear Incident in the Arctic?
Many European countries share radiological monitoring data with each other, and this is made available to the public through the Joint Research Council: https://remon.jrc.ec.europa.eu/

I'm not sure if it's possible to get historical data, but if so it could be interesting to have a look at data from January.

dll··on Culturalism, Gladwell, and Airplane Crashes
I totally agree with you here. Culture != race, and to ignore culture means that you are not seeing the whole picture. Anybody who works internationally and ignores cultural issues is going to have a bad time. Acknowledging cultural differences does not have to be negative, and it certainly does not make someone racist.
dll··on EDL leader Stephen Lennon jailed for false passport offence
How is it that somebody using a false passport can get out of a US airport once the use of such a passport has been identified?
dll··on Live air traffic of the world
The orange planes you see are from the FAA ASDI Data. That feed is delayed by 5 minutes. I would guess the site is meant to ignore the FAA data where ADS-B data is available, but in this case it looks like the call sign is incomplete in the ADS-B data.
dll··on Need a PhD Topic? How about cops in traffic
Surely this depends a lot on where in the world you are? I regularly break the speed limit while overtaking police cars in the UK and have never been pulled over (but never by much - I figure there's too much work involved to give me a ticket for only going 5 miles an hour over the limit). In fact, I've unintentionally overtaken police while going over the limit in Qatar and the US as well without being pulled over - both places where I'm more fearful of the police than when in the UK.
dll··on Netflix live in the UK
I also do this and couldn't use any of my credit cards. My UK Debit card (Lloyds TSB) worked fine though.
dll··on Show HN: Smozzy (for Android/T-Mobile) - browse the web without a data plan
I remember getting an Ericsson (A2618?) phone in around 2000 that was advertised as a WAP phone and being very disappointed that it only supported WAP over SMS (UK networks didn't allow that - I think the closest network with support was in Greece).
dll··on KLM pushes to resume passenger flights after tests
Profit is nothing to be ashamed of, but saying the skies are free of ash and safe to fly in because of a couple of test flights? It seems to me that the airlines are more scared of losing money than they are of losing planes.

Flying done properly is safer than crossing the street and I'm happy to take that risk. Flying through an ash cloud is not something that generally turns out good for aircraft engines; even if an initial inspection shows that all appears fine with the aircraft and first stage fan blades, a borescope inspection may reveal clogged turbine cooling air passages (see Grindle, T., J., and Burcham, Jr., F. W., 2002, Even Minor Volcanic Ash Encounters Can Cause Major Damage to Aircraft).

If once all this is done airlines feel the need to charge more for tickets then so be it - I'm happy to pay more if it's because of safety concerns.

dll··on KLM pushes to resume passenger flights after tests
The longer restrictions are in place, the more airlines will push to be allowed to fly. I was due to fly from the UK to Qatar today, and I would much rather delay further than take any chances. Safety should be more important than profit.
dll··on German family granted political asylum in U.S. over home schooling
Why did they go to the US? As EU citizens they could have moved to a country that does allow home schooling quite easily. I'm in the UK and home schooling is legal here. I guess that the immigration judge didn't understand that as Germans the Romeikes have freedom of movement in the EU and so could easily have avoided persecution.
