arichard123··on On Being an Engineer in 2026
It's all about trust
arichard123··on Patrick Stewart has died
I'm not sure a medieval king would take that swap. Maybe for EU poor.
arichard123··on Shopify replaced Redis with MySQL for inventory reservations–and it scaled
I had a client and they weren't to bothered if they sold the last item twice, they would call the customer, apologise, and offer a discount on an alternative and keep the sale.
arichard123··on How to Start a Ruby Meetup
I've built a site https://www clublaunchpad.com/

It's a Kickstarter for groups that want to feel like they are a club. This helps with the chicken and egg problem.

UK only at the moment but that's easily changed if anyone asked interest elsewhere.

arichard123··on Britannica11.org – a structured edition of the 1911 Encyclopædia Britannica
This is good. I picked up a copy of the encyclopedia britannica from 1973 and quite enjoy browsing that rather than the internet. The articles seem well written, and as mentioned here, you have the fact and the history and everything all mixed in to some articles, and it's super interesting.

I highly recommend getting an old set of volumes.

arichard123··on Children and Helical Time
We were discussing this last night. The solution seems to be we need to do very boring things each day, like stare at paint, watch grapes grow, etc, but then do that with different people in different places. In this way, each day seems very long, and retrospectively the changing of place and boring thing means there's a lot to remember.

I think it does mean though that optimising for this is probably not the thing to do.

arichard123··on Go ahead, self-host Postgres
I've been self hosting it for 20 years. Best technical decision I ever made. Rock solid
arichard123··on The Walt Disney Company and OpenAI Partner on Sora
Is this some kind of pre-AI crash long game? Does that make any sense?
arichard123··on Ask HN: My family business runs on a 1993-era text-based-UI (TUI). Anybody else?
I remember using a TUI for a Bank in the UK, and them switching to a web-based javascript system. Because the TUI forced keyboard interaction everyone was quick, and we could all fly through the screens finding what we wanted. One benefit was each screen was a fixed size and there was no scroll, so when you pressed the right incantation the answer you wanted appeared in the same portion of the screen every time. You didn't have to hunt for the right place to look. You pressed the keys, which were buffered, looked to the appropriate part of the screen and more often than not the information you required appeared as you looked.

Moving to a web based system meant we all had to use mice and spend our days moving them to the correct button on the page all the time. It added hours and hours to the processing.

Bring back the TUI!

arichard123··on A classic graphic reveals nature's most efficient traveler
I don't think the average horse is heavier than the average cow.
arichard123··on The cost of turning down wind turbines in Britain
I'm on the octopus agile tariff that has 30 minute pricing and an API to query it. Prices for tomorrow published at 4pm today. So the pricing bit is sorted. Just need to make the devices understand it now.
arichard123··on Bots are getting good at mimicking engagement
But if you're the only one doing it because the competition haven't figured it out, then you win in until they do. You can outbid on each ad.
arichard123··on What if I don't want videos of my hobby time available to the world?
Airsoft is probably played in a private woodland.
arichard123··on How can England possibly be running out of water?
But "investment" as the water companies define it is every penny not taken as profit. Staffing costs? Investment! Fixing leaks? Investment! So that figure sounds like money above and beyond, but I don't think it is.
arichard123··on UK government states that 'safety' act is about influence over public discourse
The claim was a pub doesn't track your identity. I think I proved mine did.
arichard123··on UK government states that 'safety' act is about influence over public discourse
My local knows exactly who I am, that I'm over 18, where I live, who my kids are, how old they are, what I like to drink etc.
arichard123··on The $25k car is going extinct?
Americans have complex post tax rules. I think their normal is a pre-tax figure. Also, it helps if you are comparing across territories I guess.
arichard123··on Mozilla Firefox – Official GitHub repo
Hang on. If they are deterred, then by definition they are not valuable contributors. They have not contributed. If they have contributed, they were not deterred.
arichard123··on My sourdough starter has twins
How surprising to find this here. I've just started making sourdough bread. It turns out that I can't make it like the local bakery, but actually, that's fine. I had to really think? Do I like open crumb? Actually no! I want sandwich bread.

I've been exploring what I can get away with. Leaving the bread to rise overnight on the counter? Yep. It's fine. Leaving the starter for 2 days instead of feeding every day when it lives on the counter. Sure - no problem. Knock it back or just quickly shape. Doesn't matter. Bake at 1.5 or 2 or 2.5 the size. It doesn't matter enough.

Things that are not fine, shaping the bread, leaving it to rise in the oven which is on a timer and then the oven turns off but I'm not back for an hour to take it out. Crust too dry!

Your mileage may vary of course. But sourdough just seems so much more forgiving than a fast acting yeast.

I've yet to see if I care about a difference between a proper knead after the first rise or just a quick shaping. It's quite fun trying the different possibilities.

arichard123··on Git without a forge
I ran a ssh server for a while to store git repositories. We had some with secrets in and I didn't want them on github. I needed to provide read only access and read write access for only some of the repos. I ended up with a bash script that configure system users and groups and permissions to do the job. It's here:

https://github.com/artumi-richard/ssh-git-hosting

I stopped using it years ago. It had the additional advantage of no artificial limits (file sizes etc).

arichard123··on Scientists are learning why ultra-processed foods are bad
Ultra processed people by Dr Chris van tulliken and for for life by Dr Tim Spector are good reading on this. The first is more focused on this issue.
arichard123··on Laptop Ports: Is USB-C only fine, or should I get HDMI,USB,Audio if I need them?
I'm using the AMD version of the framework 13" laptop with a usb dock which cost £30. The dock has power display port usb A and c ports ethernet headphone jack and card readers. It all plugs into the framework laptop with one cable and it all works well. It's small and light. It gets warm to the touch.
arichard123··on Sleep duration, chronotype, health and lifestyle factors affect cognition [pdf]
I had a similar thing until I stopped eating a certain brand of muesli. A different brand with seemingly the same ingredients was fine. I think it's something to do with processing of dried fruit. I believe there was some reaction between that and the alcohol I consumed later in the day. I only realised it was breakfast related on holiday and my breakfast habits changed. I found drinking to be consequence free as opposed to 1/2 a pint causing a certain headache the next afternoon. I experimented when I got home and completely solved my problem.

I was also in my early 40s when this happened for what that's worth.

arichard123··on Ask HN: What are you working on (August 2024)?
I'm trying to solve loneliness and improve civilisation.
arichard123··on Foliate: Read e-books in style, navigate with ease
If notes are stored as json maybe it would be easy to write a program to transfer notes from the old hash to the new one
arichard123··on The UK can go back to being the richest country in the world
This is how I feel actually. I live in the UK and the new government has started doing very sensible things. They are actually dealing with a lot of points made in the comments here. I look at the weakness of the 2 presidential candidates in the US, the rise of the far-right in the two European powerhouses of France and Germany, and the risk of deflation in China and I think, gosh! Maybe this is right? We are looking like the stable sensible choice, at least for now.

Maybe, we have, as a country all agreed the Brexit was terrible, and things can be done better and maybe we've handed power to the right people.

Let me start with the Eton/Posh thing, the new cabinet is not that. The new parliament is not that. 80% of the cabinet are comprehensive educated:

https://www.telegraph.co.uk/politics/2024/07/05/most-state-e...

The head of health had Kidney cancer and was saved by the NHS. The head of housing grew up in a council house, the head of prisons is a well known employer of ex-prisoners, the head of science used to be the head of R&D at GSK. The list could go on. As Starmer would say, it's people with "skin in the game" having the power.

And the fact they are bringing in non-politicians to get jobs done, superb.

Specifically on the splitting of the country between north and south to do an analysis, I do think that is valid, and instructional. We have seen various countries over the last 150 years achieve high growth when they have got focused on catching up to the better countries. The US grew quickly when it was catching up to the UK after the industrial revolution, and the UK grew quickly when we were catching up after WWII. China grew quickly when it was catching up to the west. Then, once it's done, growth goes back to a normal 1-2%. Well, perhaps, the UK can have the North catch up to the south and provide the growth. I look at what Manchester was 15 years ago, what Leeds was 15 years ago, and I think, sure, that's completely do-able.

arichard123··on The best way to have complex discussions?
I built a pseudo anonymous forum system for a client. He would give out logins, so he could monitor behaviour and participation. It was used when two large UK charities merged. Be then produced a report based on the ideas that came from it. I don't know if he took the idea further.
arichard123··on Setting up PostgreSQL for running integration tests
The article mentions copying databases using templates. Once your database has got big enough, that might not make sense.

You could use a zfs fs for your cluster, snapshot it, then mount it in a new cluster. This would prevent copying the data, as zfs would do copy on write. So you get your isolation, and speed on large DB's. You do need to run a new postgres cluster though.

arichard123··on Keep your phone number private with Signal usernames
Well I don't think I should be told what apps they use
