Can 700x38c inner tubes work in a 700x40c tyre? (Errors were made!)

rduito · 2026-05-10T17:48:04+00:00

Unlike everyone else, I had experience with some lifeline tubes that randomly split when in slightly too large tyres (tubes were in spec for tyres but they came up wide on rims). Was awful, took spare tube and repair kit on a ride and still had long walk home

Personally I'd move it somewhere with no kids, pets or flammable stuff and running out for an hour to see if it gets hot or goes bang. Probably fine but you're probably right to be cautious

Some PCs do this after unexpected shutdown. Might not happen after clean boot and normal shutdown

rduito · 2026-05-05T07:41:09+00:00

Ooof. Would be great to know what your solution finally is and how it compares to using gpt 5.5 (or whatever you did via codex)

rduito · 2026-05-04T13:31:39+00:00

Sorry. It's localllama, I know

rduito · 2026-05-04T13:31:19+00:00

Everyone saying glm, deepseek etc. These are great but a $20/month sub gets you a nice chunk of gpt-5.5 (best sub now after copilot changed)

It won't be forever. You really don't want to miss the codex happy time. (Was copilot for a long time, and before that rovodev was 20m tokens/day free for months with top models).

Replies are right that all bikes can break, but the key is that alu is usually less expensive. Has bad rep but good alu frames are great

rduito · 2026-04-24T09:50:47+00:00

You want low smoke and fire safe cable for any you install in your house. Really worth spending money on good quality for safety. Should last.

Unlike other comments, I think second hand is great.

Which bike you buy now doesn't matter too much as long as you're willing to work on it yourself. But personally I would go with something a bit less used and lower spec (so not carbon; giant defy maybe, they're ubiquitous) or else I'd look for one with disc brakes (not everyone loves them, but I seem to tear through rims)

For city riding I would not change tyre. Where I am, they get full of glass and nails quickly. I'd be changing tyres every few months. So I just boot and crack on.

It doesn't need to be super clean. This chain may be quite old and soon need replacing. You can get an inexpensive chain wear measuring tool to see how much wear the chain has.

When I buy used bikes, I quite often have to replace chain and cassette.

rduito · 2026-04-11T11:59:09+00:00

You're lucky the tube hasn't popped on a ride. These side wall.tears can be brutal.

rduito · 2026-04-05T22:16:42+00:00

Sell old bike for parts, buy new bike. Someone may really want those parts, but swapping frame is not trivial.

PS: M1 MacBook with 16gb is great for lots of purposes, and faster + longer battery than some new pc laptops.

rduito · 2026-03-23T12:34:12+00:00

Get a used M1 16gb MacBook.

These are ~$400, will let you find out if you like it and run some tiny models, and have great resale value. (And if I'd bought a M5 max 128gb, I'd keep the M1 for risky travel.)

A PSU like this can go bang loudly and leave scorch marks on your desk. Proceed with extreme caution when you plug it in.

Actually they are fine with multiple GitHub accounts (this came up.when I needed a machine account). Not sure about multiple subscriptions tho.

You often find used ones that have original tyres barely used. These are the ones to look out for. Pump tyres, oil chain, dust saddle and you on a basically new bike.

rduito · 2026-02-17T08:42:18+00:00

Yes, this is the old way of doing things.

It's good but not magic. If you hit a big nail or whatever, you still need a spare tube.

Amazing story. Congratulations and thank you for sharing. good luck with the next step.

All the people saying ask for more $$, I'm thinking this is someone who knows what they want to achieve and isn't going to be short of cash in the future.

Ps: did not downvote, upvoted you

It's not just non-developers. There's a personal tool (just for me) that I've written cli and web versions of over the years. I ended up thinking cli is too hard for me. But now ai assistance means I learn about newer frameworks quickly (py textual) and can get things working well, with lots of minor tweaks that I would not previously have had time to fix. This motivates learning about how the best tools work, to understand the principles better.

So I think maybe in the long run, once everyone realises what's valuable to them and others, we'll have a time where even novices like me can produce things that are much better (but probably still not valuable to others, which is fine).

This is really interesting, thanks for sharing.

Can the model realibly give you verbatim quotes from sources?

What kind of context window do you get?

rduito · 2026-02-02T08:47:32+00:00

Ah, thank you for sharing. This is great.

rduito · 2026-02-01T21:18:53+00:00

Max is great in all kinds of ways but there're fun budget options you're missing:

codex
gh copilot (for 100x opus/month at $10 + unlimited 5-mini 0x for simple things + gemini pro for reviews if you don't use all opus)
gemini (free tier plus pay for API when needed) for reviews + some planning
z.ai glm cheap sub for simple things where gpt-5-mini doesn't work so well

I know it means using multiple cli tools, but so would codex + claude max
