Change the URL: /2019" rel="nofollow">https://skyline.github.com/ /2019

It's a travesty that there's no UI for something so basic in 2021, that it can only be done by manually editing the URL like a barbarian. Truly a blast from the past, but not in a good way. Not the first time that GitHub has hidden features behind URL editing...

On the contrary: A simple, easily manipulable URL may be the best UI. It's standardized, understandable, and practical to use.

Also, it's mostly a toy, so whining about missing UI features is probably a little silly.

Runs at about 18fps in Firefox/Ubuntu 20 on a 4k monitor with Titan XP GPU. Seems a little slow for this scene. I would be interested to know what is slowing this down, unfortunately not proficient enough at WebGL profiling to find out.

It's probably just Firefox being Firefox again.

I think it can switch drill bits to make fine-passes, and sanding/deburring. I could also be wrong, but I'm lazy enough to want that automated, so CNC probably does it.

Deep pockets with fine corners are very tricky to machine, since it's hard to make an end mill that's all of long, narrow, and tough enough not to break. I'm sure it's possible, but it would be expensive, and that's before we even talk about the complex tool paths and consequent setup overhead that'd be involved. (And that's assuming there's nothing so deep it'd require EDM, in which case don't even bother asking, yo…

Related: I finally remembered enough of this to look it up successfully! While it's quite old - as I recall, I first saw it posted, in classic photocopier-samizdat style, on a wall of my grandfather's machine shop, when I was a tiny child and he nearing retirement age - I feel it may have new relevance, in these exciting days of computer-aided design and machining, and so post it here for the benefit of all and sundry.

"The Designer" - Author unknown.

    The designer sat at his drafting board
    A wealth of knowledge in his head was stored
    Of what can be done on a radial drill
    Or a turret lathe or a vertical mill.
    
    But above all things a knack he had
    Of driving gentle machinists mad.
    So he mused as he thoughtfully scratched his bean
    "Just how can I make this thing hard to machine?"
    
    If I make this body perfectly straight
    The job had ought to come out first rate
    But it'd be so easy to turn and to bore
    That it never would make a machinist sore.
    
    So I'll put a compound taper there
    And a couple of angles to make them swear
    And brass would serve for this little gear
    But its too damned easy to work, I fear.
    
    So just to make the machinist squeal
    I'll make him mill it from tungsten steel
    And I'll put these holes that hold the cap
    Down underneath where they can't be tapped.
    
    Now if they can make this it'll just be by luck
    Cause it can't be held by dog or by chuck
    And it can't be planed and it can't be ground
    So I feel my design is unusually sound.
    
    And he shouted in glee, "Success at last!
    This goddam thing can't even be cast."

what's the word: not feature creep but ... defocus? instead of fixing their completely broken search they are doing what now?

This thing looks like a toy project by a group of designers and frontend developers. Are you suggesting that their skills could have improved the search somehow?

Searching should be async and shouldn't block typing.
