sytelus··on Hertz to sell 20k EVs in shift back to gas-powered cars
Someone told me if butterfly door gets jammed (and it would in rainy weather), it costs $20 to fix just one door! This person has sweared that he will never ever buy another Tesla again. l How did Tesla didn’t got this right?

Also, Hertz models are watered down low range ones.
sytelus··on Hertz to sell 20k EVs in shift back to gas-powered cars
Every time I wanted to rest car, I wanted Tesla but I always ended up getting gas vehicle because price difference was usually more than 2X. Hertz simply couldn’t beat price proposition of Kia, Toyota etc.
sytelus··on Hertz to sell 20k EVs in shift back to gas-powered cars
Article says that the reason was huge mainly costs which I don’t understand. I thought EVs should have fundamentally much lower maintenance costs given dramatically reduced moving parts. Teslas need far less often oil changes and other services. Also, Tesla should theoretically lasts for million miles while gas vehicles rarely go beyond 2k. So, average TOC per mile should be very small for EVs. Where does math go wrong?
sytelus··on Google lays off hundreds working on its voice-activated assistant
Wow... What is going on it tech? We are just 10 days in the new year and every day there has been surprise layoffs!

Unity

Twitch

Several startups

And now.. Google!

This is at the same time when stocks are almost all time high :).

sytelus··on Twitch to Cut 500 Employees, About 35% of Staff
Unity is doing 25% layoff. Some other company laid off all 200 employees.

What’s going on suddenly? Did the holiday earnings sucked for tech? Is it new tax laws?

This is about the worst written "beginner's companion". Not sure what the purpose is here.
sytelus··on My 3-year experiment as a digital nomad
That's what I was thinking... Car and trailer pulls you down to local places and too cumbersome. A much better option is just fly to some place, rent something for 1+ month (or even a hostel if you want to go really cheap) and live there like a local. Staying in one place for at least a month (ideally 3-4 months) is very important so you don't have urge to checkout everything in short period and get distracted from the work. The idea is to be local and live like local.

For computer setup, I would highly recommend 17" laptop + portable monitor (for example, https://www.amazon.com/UPERFECT-Resolution-2560x1600-Raspber...). I also get beefy laptop with GPU with 4k display. I usually add iPad as my 3rd display for music or whatever.

sytelus··on Moore vs. United States: Tax Unrealized Income Case
No, you should not. Taking loan is very different than paying taxes. If you house goes up in value by 10% every year, you shouldn't have to pony up that much tax each year. But you should be able t take loan against your house because it's a commitment for returning that money.

Imagine, I have $1000 unrealized gain in year1. Next year market tanks and I now have -$2000 in year2. Year after that market goes backup and now I have $0 gain in year3. If I hadn't sold my investment for 3 years, I have net gain $0 and I should pay $0 tax. However, taxing unrealized gains means I will have to pay tax on additional $1000 that I never had.

sytelus··on Moore vs. United States: Tax Unrealized Income Case
This sounds terrible. The whole idea is that you don't realize gains unless you have to. That is, don't sell your long investments! If gains are unrealized, how do you even pay? You must sell your assets to feed hugry monster called government.

There are real experts on AI safety. the way to distinguish between them and the others is simply ask where is the code for your research?

sytelus··on Simplifying Transformer Blocks
There are rarely any design "decisions". Typically, you throw many things at wall and something sticks which becomes paper. Transformer paper has approximately zero "design decisions" apart from attention block. I can imagine they just tried out various combinations, kept adding projections and went with what worked the best.

Wow... I have heard this story so many times. Question is how do you get $300M debt which probably everyone involved knew that it would be written off in short order?

sytelus··on Why AutoGPT engineers ditched vector databases
Is there any implementation of open source vector db that is fast enough to say create embedding of 100M documents locally within few hours and find ranked matches in under a second? I tried ChromaDb and it is super slow, basically unusable.
sytelus··on USB inventor explains why the connector was not designed to be reversible (2019)
More interesting question for me is what exactly made USB possible? I understand that parallel communication wasn't possible because even for small differences in wire length, data on each wire will arrive at different times and that limits speed. So, people went with serial communication. But what exactly enabled high speed bit transfer? Why wasn't it possible before? Similarly, why USB2 speeds weren't possible before? What technical advances made it possible?

In the times when so many people are up in arms against covid vaccines, we keep forgetting how things were and how these vaccines allowed to open up en-mass. Yes, there were problems but number of lives saved is just awe inspiring.

sytelus··on iPhone 15 and iPhone 15 Plus
There is NO dirth of ideas. I was hoping for duel screen, full satellite communication, 48hr battery, 3D audio/video/photos etc. These are the things that are very challenging to get right and I think only Apple can make it happen in a way to make mainstream. But nothing came through.
sytelus··on iPhone 15 and iPhone 15 Plus
This felt like really let down release. I am usually the first one to upgrade iPhone no matter what but this year I felt no attachment to any of these "new" things. Just didn't cared at all.

The things I would have cared:

- Dual screen

- AR/3D photo/video features in phone

- Much better battery life

- Full satellite communication

- OS-wide AI features, massively upgraded Siri, AI-first mobile browser, auto-complete, spell+grammer check, rewrites

- Even more AI features: Better reader-mode, PDF mode, maps infused with AI, super-res videos with structure from motion, flower/bird/food/tree/everything ID, so on and on.

What's going on with Apple?

The 2020s were "Internet in your pocket" and 2030s should be "Super smart AI in your pocket". Apple product managers feel so completely out of touch.

This is very nicely done and much more clear to follow than the paper. One question: Does LLM get to evaluate the code using tool or guess the return value of f(x)?
sytelus··on Scientists use quantum device to slow chemical process by factor of 100B
What does this mean? Can you slow down time? I would assume you must also slow down physics in order to slow down chemistry. No?
sytelus··on Scientists use quantum device to slow chemical process by factor of 100B
This is really a bad idea to study anything. Actually this is what sets aside naïve hobbyist interested in Physics vs someone studying Physics systematically and efficiently as part of PhD program. I did this mistake repeatedly. I started with annotated version of Newton's Principia, spent about a year just pulling my hair and gave up to realize how much time I had lost in all kind of minutia, noise and random things that were completely useless to develop good understanding of core principles. I repeated this mistake yet again by buying Maxwell's original publications and wasting yet another year. And then again with Einstein's original papers and wasting yet another year.

I thought I would do differently and everyone else was doing wrong. I was the one doing wrong. I didn't learned much from all these original manuscript. I also lost precious years which I could have obtained real Masters degree. It is super important to understand that original manuscripts have tons of noise and baggage that only make sense in historical context. They also have unbacked goods which are super hard to digest, if you can digest at all. A ton of experts have already spent their lives distilling these original writings that fits with everything else, easy to digest and doesn't have all that noise. So, get a good textbook and follow that. Stop chasing original manuscripts.
