tsomctl··on World’s Shortest Wavelength Laser Diode Emits Deep UV Light at Room Temperature
Because if you have an actual filter that is a small enough micron to capture pathogens, it's also going to capture all of the really fine sediment and plug up quickly.
tsomctl··on DDSP: Differentiable Digital Signal Processing
http://dspguide.com/ is a practical, not too mathematical guide. Really, I recommend it to anyone that knows math and computer science. Understanding linearity, what an impulse response is, and convolution is really useful, and intuitive.
tsomctl··on Audio pre-processing for Machine Learning: Getting things right
I spent some time using the synchrosqueeze transform to preproccess audio files before feeding it into the network. Basically, you do a cwt, and then feed the output of that into the synchrosqueeze. It basically sharpens up the cwt, so that a signal isn't spread out into so many bins. The output of the cwt is complex, and normally you through the imaginary data away. The synchrosqueeze transform uses the imaginary data to work it's magic. Figures 5 and 6 of the below pdf are good examples.

I believe I based my code of this matlab code: https://github.com/ebrevdo/synchrosqueezing/tree/master/sync...

The above matlab code is ridiculously slow, I rewrote it using sse intrinsics, and got it several orders of magnitude faster.

I hope this helps out someone. I never really produced anything with it, but I still feel it is promising.

tsomctl··on 'Megafire' in Australia Engulfs 1.5M Acres
Not sure where you are, but controlled burns are common in California. And it's expected that a small portion of them get out of control. Source: my neighbor, who's a retired wildland firefighter.
tsomctl··on 'Megafire' in Australia Engulfs 1.5M Acres
I don't know about Australia, but here in Northern California, that's not how it works. 500 years ago, forest fires were common, cool burning, and did more good than harm. Today, it's been so long since the previous fire that there's a huge amount of underbrush and dead material. When a fire comes through, it's so hot that it kills everything, including huge, old growth doug fir trees. However, it's not hot enough to actually incinerate the old growth trees, so you get left with a bunch of standing deads, and plenty of dead wood for another fire.

Brave, or smart. She lives in Kazakhstan, which doesn't have an extradition agreement with the US. All she has to do is stay there, which is harder that it sounds. We've nabbed a number of people from former USSR countries when they've gone on vacation someplace warm.

tsomctl··on How Microbiomes Affect Fear
> The team speculated that the microbiome might produce certain substances in abundance, with some molecules making their way into the brain.

I thought this was already well established with sodium butyrate. Eating hi maize resistant starch is a guaranteed way to give me super vivid, movie like dreams.

Small doses of shrooms, I'd like to add.
tsomctl··on The case for working with your hands (2009)
To each his own. I took it as him admitting his failure at "doing a good job," and his son's mental health struggles as just being a kid. Riding a motorcycle, camping in a tent, and hiking in the mountains are exhausting. I'm 29, in reasonably good health, and after a week of hiking even I am glad to take a shower and sleep in a proper bed.
tsomctl··on The case for working with your hands (2009)
He made a joke. And in the likely chance you haven't read it, I strongly recommend Zen and the Art of Motorcycle Maintenance.
tsomctl··on How Complex Modern Headlights Can Be
My daily driver has extremely low-output headlights (old school sealed beam headlights). They work great, my eyes adjust to them just fine, except when I'm around other drivers with modern headlights.

lol.

> "what you think of Oracle is even truer than you think it is. There has been no entity in human history with less complexity or nuance to it than Oracle"

> You need to think of Larry Ellison the way you think of a lawnmower. You don't anthropomorphize your lawnmower, the lawnmower just mows the lawn, you stick your hand in there and it'll chop it off, the end. You don't think 'oh, the lawnmower hates me' -- lawnmower doesn't give a shit about you, lawnmower can't hate you. Don't anthropomorphize the lawnmower. Don't fall into that trap about Oracle.

tsomctl··on Rich Californians Are Shelling Out $30k to Ease Blackout Pain
And poor Californians are shelling out $1k for small Hondas. Our local Craigslist is full of them.
tsomctl··on Things I learned when I worked at LAX
No, but I was expecting that. I believe Ublock Origin was hiding it.
tsomctl··on Things I learned when I worked at LAX
Thanks. I'm so used to uBlock Origin just working that I didn't even think of it.

So, is it only two paragraphs, or do I not understand how to use their website?

Capitalism isn't necessarily a good thing, it's just better than any other economic system.
tsomctl··on ‘This Did Not Go Well’: Inside PG&E’s Blackout Control Room
> The company, which is facing $30 billion in liabilities from recent wildfires started by its equipment

Conspiracy theory (which is shared by everyone I've talked to): PG&E turned off the power to make a political statement that they shouldn't be liable for wildfires.

Edit: by "not be liable", I mean passing legislation to achieve this.

tsomctl··on During the Renaissance, the beard was the defining feature of a man
I had the same problem. A double edged razor is better than a safety razor, but still problematic. I finally said fuck it and keep it trimmed to about 1/8 inch. As an added bonus, several women have complimented me on it.
tsomctl··on From Mac to Linux – the setup I've grown to love
T5x0 (Avoid the T540, the touchpad buttons are supposedly shit.)

I'm running a T530. Max out the ram, get a ssd, it's great. I'm probably on my third one, I keep buying junkers for $50 from eBay for the parts. I majorly abuse it. The magnesium frame likes to crack near the heatsink, the steel frame around the screen likes to crack 1 inch above the hinges, don't spill water on the table it's sitting on.

Or go to the library and photocopy the questions. I had a math instructor literally tell us to buy the old edition and photocopy the questions from the library.

tsomctl··on “Roman Biro”, complete with joke, found at London building site
> The inscription was exceptionally difficult to read, partly due to corrosion, and is only legible now following work by conservators.

The article says it is made out of iron, but wrought iron is much more likely. The Romans would have been able to make a punch out of hardened wrought iron to mark this stylus.

tsomctl··on Why we don't use Galileo's last name (2009)
When you're a small business owner, and you have potential customers calling your cell, it's polite and professional to state who you are.
