Wow - that's a lot of bits (at least for me) :)

Finally going to start soldering up one of my pcbs...

davidr, 10 months ago to castiron

Is there, like, peer-reviewed #castiron seasoning instructions out there? Science-based?

I'm sick of "this is what my grandfather taught me" or "I've always found that" info. I want F A C T S.

This is "making clear ice", "guaranteed peelable hardboiled eggs" or "how to stop hiccups" all over again.

(In all seriousness, if you @ me with anecdata, I will block you.)

Pre-covid, I had a very structured life. Every day had a pattern. I knew at the time that I was storing critical data in those patterns, but I didn't know how much.

I have lost my earbuds more in the last 3 months than in all of pre-2020 combined.

I have no clue this time. Case is empty. No idea when I saw them last, but it must be over a week. Searched the whole house and car, plus all my pants and shirts pocke...no wait! Last week's pockets!

To the laundry!

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.

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.

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...

davidr, 3 months ago to geopolitics

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.

Recent #cocktails have been

⭐Cuba Libre
⭐Long Island Ice Tea
⭐White Russian
⭐Kamikaze
⭐Sidecar

✅Between the Sheets
✅El Presidente
✅Gin Rickey

❌Bacardi Cocktail
❌Blue Lagoon

What I've learned so far is that I like a long, strong cocktail, probably with fruity flavors, especially citrus.

(I suspect the Blue Lagoon was a misfire. I like Cointreau and Triple Sec, so I should like Blue Curacao. But I felt yucky afterwards.)

#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, 8 months ago to music

So....first of all, they still sell Official Sheet #Music of popular songs. I bet it's a huge business for tribute and cover and school jazz bands, etc, but it's still funny to me

And second of all the "official" sheet music is in at least one case in a different key than the release itself.

why. why would you do that.

Ride by Twenty One Pilots (yes, I'm going to attempt to make and play my own #guitar lead sheet based on this) is F# on the radio but F on paper.

davidr, 9 months ago to Engineering

Been aiming towards a technical accomplishment for months that isn't on any statement-of-work. Getting mostly polite nods and agreements from coworkers.

Yesterday I got it working. Nodders were suddenly excited. "Hey, this is giving me ideas!"

No kidding.

Even in an R&D context, too many are project-focused instead of tool-focused. It isn't about delivering a result, it's about ending up with a capability!

#Weekend #Projects

Make my own #guitar lead sheet(s) instead of the stupid chord sheets/tabs available everywhere.

#MuseScore seems really great for this.

The only problem is that while I know about #music than a chord sheet assumes I know less than I probably need to, for instance, line the lyrics up with the beat.

But it's all a #learning process! It's OK to be terrible! Everyone starts somewhere! (he snarled through gritted teeth)

davidr, 4 months ago to OSINT

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.

I've got two recent grads in my group under my de facto...mentorship? Command?

They are both very smart. One is very confident he can do things but is less effective, one is less confident and more effective.

I'm very unused to constructive criticism and other #leadership skills so I'm not sure how to turn down the confidence and turn up the effectiveness.

I mean, I know what to do. "Test. Be skeptical of your own work/ideas."

I don't know how to say that.

I installed a #hummingbird feeder. I thought these things were unhealthy, but the gods of #birds say go ahead

Anyway, we've had 4-5 sightings from two different people, so I think it's working.

davidr, 9 months ago to blender

Why are there no #3d #visualization tools (for #python) that work like a #gamedev engine? I want to do more than rotate and zoom. I want to translate my rotation point. I want to walk around inside my #data. Let me explore parameter space directly.

If it doesn't already exist, maybe I'll have to make my own #fps style plotting tool.

** input works great! **

I like saying "set a 10 minute timer", "remind me at noon on Tuesday" or "play Song X" because I can do it NOW without have to fumble through my phone or clean my hands if I'm cooking

** output does not work well **

Alexa, what's the weather?

Today's forecast is already stopped listening

Ugh. ALEXA. What's the weather?

Today's foregone

A L E X A what is the high temperature today?

67

That's all I need!

davidr, 9 months ago to Software

I knew he was smart albeit cocky.

I stopped him on everything he was doing to concentrate on a branch he's been "this week for sure"ing for months. (Those other things weren't moving either)

I suggested that we pair-program it to get it optimized

He turned me down on Thursday

Today he changed his mind

As a parent of 5, I know how to be gentle but firm. I've been told I'm good at teaching. I love fixing things

I feel like tomorrow will be fun.

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"?

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?

davidr, 10 days ago to Finance

I'm no #finance or #stockmarket genius, but.

As an #engineer, if I had any other #data series that was pretty smooth for several years and then started getting very spiky month to month, I'd look for some underlying malfunction.
