Heinlein is problematic for a lot of reasons, but I've always been inspired by this:

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."

Mark Rober is at it again.👍🏿

Either he's the single greatest detective and criminal justice mind on earth or... SFPD is incentivized to not reduce these car break-ins.🤷🏿‍♂️

Everyone knows:

  • which vehicles are targeted
  • what streets they're targeted on
  • about the stolen licence plates
  • where the stolen goods are fenced

We all pretend not to know these things though.🤷🏿‍♂️

He didn't name the neighbourhood that ultimately fenced his laptop, but the Dim Sum there is lit! 👍🏿😋

I live in the US. I'll be visiting the UK this summer. What do I need to know/do, technologically-speaking?

I know the plugs are different. Phone service? WiFi standards? Uh...keyboard layouts should be OK.

What have I not even thought to ask?

How much an insane dinosaur will I be if I ask my junior #developer to use 2 space indents in #python vs the PEP-8 4 space waste-of-whitespace?

Actually, I think I might prefer 3, but I'm pretty sure everyone will hate me if I pick an odd prime...

@alecthegeek Oh, I have no problem looking insane to the junior dev.

This is more of an "other parents" situation. How does feel about people who use 2 space indents?

I have literally one step left on my #python #pyqtgraph "measurement distance #simulator" #data vis project and I'm suddenly like...ugh, can I even go on

Meanwhile, I woke up at literally 2am with an idea for a scheduling algorithm based around a spring network #physics model that I'm excited to try instead

(Obviously neither of these gets the trash emptied, the kitchen organized, the TV movie folder fixed or the plumber called)

#ADHD and #kinetic brains - do you have any good tricks for getting yourself to do mental or intellectual work when your brain is hyperfocused on something else?

Last few days, my brain is completely interested and trying to pull me towards certain entertainment content, but I have a lot of work I need to do for my dayjob that requires my brain to be able to focus and flow, at least a bit. And I am STRUGGLING to get my brain to stop interrupting my work focus every five seconds to tell me to play a game or read a comic.

My usual coping skills ain't working (e.g. basic mindfulness, using music to change the emotional context of work, trying to grab onto the tasks that interest me, etc.), and I'd love new ideas!

@JoscelynTransient Loud music...oh, you tried that.

How about panicking that you'll be discovered as an imposter who has been slacking off and they will chop your body into tiny bits and then fire the bits?

For me, the main impediment is not a different hyper focus (bc my work is mostly fun and interesting to me, how lucky). The main impediment is overwhelm at the hugeness of effort or a Big Boring First Step.

Finding some route around that initial hurdle often breaks the dam.

So nice to see how @rougier used Shiffman's Flocking example as inspiration for the spatial vectorization techniques on https://www.labri.fr/perso/nrougier/from-python-to-numpy/#spatial-vectorization

Such a pity that the Processing Foundation has in all these years abandoned Python... but... now we have and + + has a future!

I'll see if I can remove the matplotlib dependecy and use py5 for boids in the next weeks. I have both a bio-simulation educational demo and a "hey, I'm learning numpy in the context of creative coding" presentation in the coming weeks.

@davidr@hachyderm.io avatar

@villares derp, I've been thinking of 3D vectors so I was like...you aren't using all the components.

I agree about the shape apparently meaning it's just the normalization. I wonder if the linalg is doing the wrong direction or something.

numpy makes this hard for no reason, but I usually take row-wise magnitudes like this:

mag = np.sqrt(np.sum(v**2, axis=1))

davidr,
@davidr@hachyderm.io avatar

@villares Oh, it worked? Great!

I've only scratched the surface as well. I just happened to have been working with lots o' rows of data this summer needing to do similar vector ops.

davidr,
@davidr@hachyderm.io avatar

@villares Oh yeah, this is tricksy as well. You need to tell numpy where the broadcastable dimensions are

norm = v/mag[:,None]

The Thruway has an incredibly archaic speeding ticket system

The "ticket" they give you is actually a plea request. You can plead guilty or not-guilty. Either way, you have to mail a physical letter to do it

That's just the plea, you understand. You haven't paid or even seen the fine amt yet.

Then they MAIL back a letter with your fine in it.

Then you mail back the money (handwritten CC deets on a form)

You can get a receipt mailed back via SASE

What year is this?

I've been following @andybaio links to cool stuff on the for probably over a decade. Very frequently awesome stuff in there

However, the top item I see today is the " off-the-shelf parts ". Ooh, neat, perhaps a fun project!

2x ViperX 300 Robot Arm 6DOF: $5,695.95 ea
2x WidowX 250 Robot Arm 6DOF: $3,295.95 ea
1x Tracer AGV: $8,999.95 ea

$27k for the basic equipment + another $4k for incidentals.

"DIY" is doing a lot of work here

I came across a meme that showed someone putting oats into a greasy pan to dispose of the grease and then feed .

Since the kids have moved out, we don't go through enough jars to put meat fat into (the drain is out of the question). Win win!

Trying to confirm, google was only giving me garbage, but I found a pretty trustworthy link that specifically called out grease, rendered fat, seeds and oats.

I thought I knew that calls lemonade "lemon squash".

However, the has referred at various times (sometimes in a single episode) to "squash" (as a drink), "lemonade", "juice" and "orange juice". So now I don't know what to believe.

WTF is "squash"?

These nitwits still don't get it.

Maybe the economic metrics you've chosen to measure and maximize don't address the actual kitchen table that affect the 99%.

How are homelessness, low wages, unavailable housing, lack of union protection, terror over medical debt, etc captured? They aren't!

"The economy grew" could be like a person building muscle or like a cancer metastasizing.

Measure the right variables.

I was doing some extremely basic this weekend. Just going through pipe bomber info released by the

One task I set myself was to find the camera each video/photo was taken from. I found them all except this famous shot:

Location: https://maps.app.goo.gl/j9dddxVZSfQQZXL66

Reverse angle shows that the lightpole has to be the camera. Those exist nowadays, but except for a paintjob this light has been here since at least 2007.
