#kdtree and ball trees seem cool, but require full knowledge of the thing I'm searching for. What if it's 7 dimensional and I only know 4 of the values?

I feel like a "parallel kd tree" with a separate binary index on each dimension would work better here.

Reduce depth. Allow unspecified values. It'd also be a snap to create and search each dim in parallel.

This must already exist...

And speaking of #MuseScore

I paid for a subscription. And they are now effectively blocking #Firefox, at least on #Linux. Every fetch requires me to "verify I'm a human" so none of the images or #javascript load. It works in #chromium (for now...?)

#Web #developers, just say "no" to this kind of garbage.

davidr, 1 month ago to Cat

We got a new-to-us #cat on Thursday afternoon.

Thurs aft: It was under the bed
Fri noon: Under the couch
Fri evening: Spotted briefly coming out from under the couch

It is now Saturday evening and we haven't seen the cat in almost 24h. It's a big house with LOTS of places to hide.

Negligible chance it's gotten out. The other 3 #cats seemed to trigger on it a couple times but we still couldn't find it.

I just hope it isn't stuck somewhere...

omg omg omg omg

18yo started learning #guitar a couple weeks ago and doesn't object to being guitar buddies! I've never played with anyone!

Also 16yo is in chorus and was willing to sing the gospel song the class has been practicing!

So we just had a 3 member family #music #band

We sound awful! But we had fun! And I think maybe intrigued the 23yo...

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 #economy 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.

The #NewYork 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?

It's really incredible (and I mean very predictable, but still nice to see) how the economic sanctions against #Putin are showing up as #GOP funding problems at every level. The #NRA, state parties, etc.

If we can just freeze out the #fascists for a few years, we might recover and even gain ground.

I was doing some extremely basic #osint this weekend. Just going through #J6 pipe bomber info released by the #fbi

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.

davidr, 4 months ago to web

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

However, the top item I see today is the "#DIY off-the-shelf parts #robot". Ooh, neat, perhaps a fun #electronics 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

(also, it's a waldo, not a robot)

davidr, 5 months ago to Birds

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

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 #AI garbage, but I found a pretty trustworthy link that specifically called out grease, rendered fat, seeds and oats.

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

However, the #OffMenu #food #podcast 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"?

davidr, 5 months ago to python

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)

oh jesus, #python, please stop breaking things like this

https://blog.miguelgrinberg.com/post/it-s-time-for-a-change-datetime-utcnow-is-now-deprecated

I want naive datetime objects. I want them to be unknowable because I want them to be unalterable.

I don't want some silent function in the middle of something somewhere to "help" me by changing my datetime objects to the timezone I "obviously" mean.

I want to be in charge of my own data representations.

Here's a hot take

Irish Whiskey is kinda gross.

Even hotter take

I think I just don't like whiskey. It tastes like licking a dead branch.

davidr, 6 months ago to cocktails

Over the next couple of weeks, I'm going to try all my favorite Cointreau-containing #cocktails with limoncello instead.

Like...why is Lemon Drop made with orange liquer?

(Unrelated sidenote: While buying another amaretto, I noticed a hazelnut liquer. We'd already tallied >$100 so that intriguing item goes onto a future list.)

davidr, 6 months ago to food

Almost all crunchy plant-based food is based on rigid, fluid-filled cells. Celery. Apple. Lettuce.

Almost all crunchy human-made food is based on brittleness. Chips. Crackers.

My fellow #food madscientists, I propose a new field of satisfyingly crisp food built on the principle of the plant cell. A taut, bursty, fluid-packed membrane.

We made gushers, but we can go farther, reach higher, chew louder.

davidr, 6 months ago to ADHD

Was it stupidity, denial or just obtuseness that made me not recognize #executivedysfunction for 50 years? Not even an "oh, it's that feeling again where I'll do anything I can to avoid this simple 5m task, maybe listening to music will help".

Or #RSD. Prooooobably most people aren't assuming that everyone not currently actively praising them is deeply angry at them for unspecified reasons.

Anyway, talk to your doctor and try some medication. It's pretty great.

Got yet another #meeting request that ignored my #outlook calendar but listed me as "required".

This time I declined and "proposed a new time". Politely but tersely noted if I was truly required I wouldn't be available at that time but that "my calendar is up to date".

My proposed new time is in a slot their calendar says busy. Huh!

#data #datascience peeps, hear my cry!

Let's say there's a periodic process that I'm sampling. The period is changing slowly (<1% per cycle). I get a sample on a lot of the cycles, but not necessarily every one.

I'm sure I can bodge together an #algorithm to figure out the "fundamental period" and how it is changing over time, but I also bet something already exists.

What's my #search keyword?

davidr, 7 months ago to guitar

Having a heck of a time figuring out what #guitar chord #GregDavies is playing here. The intro is G Em Am D. "although she will concede" looks like a C. "the cold rather gets to her knees" is ???

https://www.youtube.com/watch?v=zPRxSi79scA

Ultimate Guitar thinks the C is Am (by ear maybe, by eye no way) but worse thinks the unknown chord is a D7. That's definitely wrong both by ear and eye.
