Any question answered...

Arcsin(1/3) is roughly a third (it's 0.339 and lots of other numbers) so I'd you only need an approximate result you could just use that figure. It simplifies things a bit.

Can anyone with better googling skills than me, find these little plastic boulders? About 10mm in diameter.

Like this but with no hole, and 10mm?

In the limit, a random walk on the lattice is a Wiener process whose probability distribution after time t is normal and rotationally symmetric. So for the discrete case if each block moves for n steps picking a direction uniformly at random at each step then you would end up with an approximately circular "pile"

They’d be perfect! Link?

I’ve found loads of options on eBay. Thanks a lot! The construction site play set will not run out of raw materials now :)

Further to my search for a nice quality trekking bar (the world really needs to settle on a name for these things) I may try the Nitto KT; it's a little longer than my spec but at 720mm I'll give it a go and there's enough grip space to trim it back if need be.

Is there a "standard" 1 1/8 internal headset bearing size?

Is there a "standard"

There are two main standards, 41.0mm OD with 36° internal chamfer, and 41.8mm OD with 45° internal chamfer, sometimes called Campagnolo or Italian pattern. Both have 45° external chamfer. Bearing thickness ranges from 6.5mm to 8.5mm, a correct match being more important for the lower bearing. There are other patterns, but they are rare and considered obsolete.

Ah cool! I thought it was an exam question or something with the result being in terms of pi.

Looks like you found your answer though! Also, not sure if it'll be useful for this case, but have you seen this sort of thing?

Sound. I'm 99% sure its 45/45 and I've ordered more batteries for my verniers so i can properly check instead of just guessing. Thanks!

It’s called salt creep, if nobody’s responded yet (only did a cursory check). Happens in salt water fish tanks too.

Are the numbers on the bearings?

Thanks @mmccarthy and @wence. I think I will play around with some basic graphics code. My maths isn't great though (e.g. I found Bresenham's circle drawing algorithm, but couldn't really read it) so needs to be fairly simple algorithms.

Years ago someone posted amazingly bad American food YouTube videos. Some were frightening in terms of how badly food was handled from a hygiene perspective others were people just assembling various packet foodstuffs.

Can anyone point to where they are?

Thanks. Don't have a photo at the moment, but I can see the top of a crystal peeping through the solution now.

This is infinitely more successful than our last attempt.

Thanks. That's really handy as my first hits all have quite large ODs

Isn't this all American food videos.

Chefreactions is good for shit American "recipe" videos and a funny guy talking about it.

i've been talking to a company about a job in the Humberside area. I must admit that of all the places in the uk i have considered as possible locations, this wasn't one of them, until now.

but i like the sound of the job.

anyone know this area - north Lincolnshire, Humber etc? any advice welcome....

somewhere with a train station with London connection obviously a bonus!

what's the go to small but good laser printer for at home b&w only.

(fuck another inkjet and their cartridge nonsense is what i believe is the opinion on here)

Talk to me?
In laws live near grimsby.
Trains are a dilemma. Humberside is east. Not North. that's different. that'll help for a start.

Manchester - Sheffield - Grimsby on the TPE is a nightmare for regularity.
Getting to London from Grimsby requires changing at sunny Doncaster.

let me know what you want to know.

Brother. They're all much of a muchness in terms of models. You've got the right idea with laser b&w.

Hi - thanks for the response.

Yeah, i can see that train connections aren't the best. it looks to be an area where people mainly drive to wherever they need to go.

i guess at this point i'm just interested in where would be an ok place to live, where i could get to Humberside ports area within say 30 mins to get to work, but still not have a default 3 hours plus drive as the only sensible way to get back to London. so either an ok town or a nice part of the countryside.

Likely we would have a flat in London if this move ends up going ahead as there is no way that my OH would agree to completely moving out of London, which I kind of agree with.

Keelby would be my choice.

Immingham where I left at 18 is not somewhere I would return to.
