jonatron··on Blue Peter discovers the Internet (1995) [video]
Blue Peter bury time capsules and dig them up occasionally. I think I remember watching one getting buried. I just looked up one being dug up, it was much less interesting than I could've imagined.
jonatron··on Electric heat storage (Night Storage Heaters) (2019)
I was thinking about a similar idea. I couldn't find a suitable DC immersion heater to connect directly. An off the shelf on-grid or off-grid inverter wouldn't have made sense either. A massive variac wouldn't be cheap. A purpose built inverter/mppt would be good but I'm not an electrical engineer so I don't know how to make one.

Water can't really go above 100c without being under high pressure though.
jonatron··on Electric heat storage (Night Storage Heaters) (2019)
My electric only house used to have storage heaters. Just had a mini split air conditioner installed. It's much more efficient [COP], so should pay for itself pretty quickly.
jonatron··on Ask HN: Which is your favourite instant noodle?
Baijia Sour and Hot Sichuan Broad Noodle
jonatron··on Ask HN: Good resource on writing web app with plain JavaScript/HTML/CSS?
The Django Girls tutorial is supposed to be good for beginners. It takes you through everything up to Django Forms: https://tutorial.djangogirls.org/en/django_forms/ . I don't think there's any javascript in that tutorial. That combined with the Django Documentation: https://docs.djangoproject.com/en/4.1/topics/forms/ should be fine.
jonatron··on Mild autumn weather has sent European gas prices plummeting
I'm on a time of use electricity tariff, and last night it was around £0.02/kWh between 3AM-5AM. The standard price cap rate is £0.34/kWh
jonatron··on A sand battery could transform clean energy
Storage heaters might make comeback if gas prices remain high, because intermittent wind power and smart meters make it possible to use electricity when it's windy and cheap.
jonatron··on Wiring my home with fiber
That conduit would look terrible. Most people care about how their houses look. Decorative trunking exists: https://www.d-line-it.com/wp-content/uploads/2021/02/1240-x-... , I've used it, and it blends in well enough.
jonatron··on Wiring my home with fiber
I'm guessing you're in the UK. Even in my relatively new house (80's), almost all cables are chased in, no conduit anywhere. Standard construction in the UK could be improved by just doing basic obvious things that other countries do.
jonatron··on Wiring my home with fiber
You'd think simplex short boot LC would be able to get through small conduit. Although you can always stick the fusion splicer on eBay, it's not like it's worthless now.
jonatron··on Facebook Down?
Doesn't load for me in the UK
jonatron··on Python 3.11.0 final
Is there any chance of making Octopus's vendor.bundle.js less than 15MB? It takes time to load on any device, and the size makes the site unusable on mobile.
jonatron··on Python 3.11.0 final
Do you know if BAML Quartz is similar (size and Python 2)?
jonatron··on AWS buys 100 diesel generators and that's just for Irish datacenters
The price of gas and electricity is so high that diesel looks relatively cheap.
jonatron··on A global house-price slump is coming?
France also does long term fixed mortgages. No idea why.
jonatron··on Simple, Fast, and Scalable Reverse Image Search
I used ORB descriptors and Hamming Distance for a fuzzy/partial/inexact reverse image search at my last job. While it didn't scale like the OP does, it found some really interesting fuzzy matches.
jonatron··on Fake Men on Hinge
The autocomplete for googling "hinge only" is "hinge only showing fat" and "hinge only showing ugly". There's pages and pages of people saying they get shown nothing but the least attractive people on hinge, which would cause real people to just delete it.
jonatron··on Ask HN: Which boring technology do you still use?
Django 1.0 was released in 2008! If old is boring, then Django is.
jonatron··on UK banks and lenders suspend offering new mortgages amid market turmoil
They're probably avoiding an immediate kneejerk emergency raise, which would look like they're panicking. If they wait a little bit before they raise, it'll look more calm and considered which should give the market more confidence.
jonatron··on LXC and LXD: a different container story
Back in 2016, I thought it'd be nice if LXC/D had something like a Dockerfile. It would just be a small layer or tool to do it, proved with a little python script: https://github.com/jonatron/lxf
jonatron··on Debugging the Postgres query planner (2018)
Postgres is the odd one out. MySQL [1] has plenty of index hints, including FORCE. In the proprietary world, MS SQL Server and Oracle also have query hints. I don't know if there's anything other than a wiki page [2] that hasn't been updated since 2015 that justifies it.

jonatron··on Ask HN: Where are the good platforms for contract work?
Someone I know has recommended YunoJuno. Edit: It looks like it's UK only.
jonatron··on The dumbest way to solve a maze [video]
There is unfortunately a dumber way to solve a maze: https://youtu.be/v2uAipnt2nw
jonatron··on Shortest URLs on the Internet
Although it's nowhere near as short as ai , I like bl.uk
jonatron··on Ask HN: Work Culture Canary?
In a small growing company, when someone starts leaving the toilets in a mess, there is a bad hire. Knowing you work with at least one uncivilized person changes the feel of the company.
jonatron··on Our screwdriver took three years [video]
It's a Canadian thing.
jonatron··on The toll of dating app burnout

jonatron··on What would a “good” WebMD look like?
To take the example of Aspirin and Essential Oils, NHS has no ads and has information on Aspirin https://www.nhs.uk/medicines/aspirin-for-pain-relief/ , but doesn't have information on Essential Oils. It probably doesn't list supporting evidence because most people don't want to read it and wouldn't understand it.
jonatron··on WireGuard Servers Running from RAM
Remember when Reddit removed the warrant canary?
