Can't understand why there doesn't seem to be much wider excitement at all, around "our Apollo 8", that I've been waiting decades for (late 40s here).

Apparently here in the UK our schools are hardly even hyping it.

I'm watching it rapt, but also wondering which KIND of leaky will result in a scrub..

Thanks, though I think part of longhard feeling labourious these days is RSI sadly. I did try to correct my scrawl for effort and legibility a while ago, but it just wouldn't stick!

I got PT Mono in the game, but this gave me the kick I needed to remember about ProggyClean[1] and track it down. Used to love it many years ago, time to give it another spin and see if it holds its own.

There's a vector version[2] now too!

I love taking notes by hand for better retention, but (my) longhand is just too slow. It's also an inconvenient format for representing a hierachy or graph of connections.

Anyone else into what my high school biology teacher loved referring to as "pseudo-arachnomorphic diagrams" (Mind Maps[1] / Spider Diagrams)?

They're still my primary paper-based realtime note taking method. They seemed to get a lot of attention a couple of decades ago, but I don't hear them mentioned much recently.

Lots of online/local Mind Map tools available, but I've never really gelled with them (though you do get self-organisation of the nodes!). Once in the digital realm I'm more likely to make notes in Markdown.

That's very helpful and clear, thank you

This is lovely. I'd hoped to see The Coral Beach on the Isle of Skye[1] featured. In retrospect the bits are maybe a bit large[2] to be called "sand".

I'm sure it's very much frowned upon these days but somewhere I have a 35mm film canister full of the coral fragments.

Bit twitchy indeed but still fun. Instantly took me back to "rubber glenz vectors" in classic Amiga prods[1]

Really cool idea, will try to have a play later.

The concept reminds me a little of some books available in the 1980s that combined a story with little BASIC type-in programs[1].

More modern alternatives along a similar line are also available[2] but kiddo here is more interested in learning Lua for Roblox :)

Great point, thanks.

If you just see the conclusion I think it's hard to immediately grok how rotation can arise from this.

This is a great technique for cheaply doing 3D starfields etc on 8-bit machines.

Look ma, no sine table!

I've been thinking about this since [1] the other day, but I still love how rotation by small angles lets you drop trig entirely.

Let α represent a roll rotation, and β a pitch rotation.

Let R(α) be:

    ( cos α   sin α   0)
    (-sin α   cos α   0)
    (   0       0     1)

Let R(β) be:

    (1     0       0   )
    (0   cos β   -sin β)
    (0   sin β    cos β)

Combine them:

    R(β).R(α) = (    cos α           sin α          0   )
                ((-sin α*cos β)   (cos α*cos β)   -sin β)
                ((-sin α*sin β)   (cos α*sin β)    cos β)

But! For small α and β, just approximate:

    ( 1   α   0)
    (-α   1  -β)
    ( 0   β   1)

So now:

    x' = x + αy
    y' = y - αx - βz
    z' = z + βy

Yay!

Oh no

This is fantastic. I have a TUF-3 but to use one to tune an acoustic was a real trip :)

Instructions unclear, gimbal locked

"hey why'd you make that bid?" is a valid question that must be answered during a game of bridge..

Good article, but I really really enjoyed the (non-deterministic!) falling objects with physics engine at the top of the page.

Looks super cool, nice job!

Twisted and great.

Looks really cool, I'll try it later.

Just wanted to let you know that for me, on FF and Chrome, your blog is rendering rgba(235, 235, 235, 0.64) text on white BG, and I'd really like to be able to read it.

Edit: Also immediately reminds me a bit of UnReal World[1], in a good way

There's a whole open challenge[1] - but you might be thinking of this[2] prod.

Possibly unhelpful for OP, but for MSVC try /NODEFAULTLIB for specific libraries, or IgnoreAllDefaultLibraries to remove everything not explicitly specified to the linker.

On x86 only, if you need to cast floats, try /QIfist (deprecated) to avoid hitting _ftol. Doesn't work for x64 or ARM.

in bitcoin terminology it is actually called policy rather than consensus, meaning you can choose your own config and still meet consensus rules.
