It really doesn't make it clear how this works, and I can't find a consumer facing help article. Does this just email me a code or what?
sf_rob··on Federal Reserve pledges asset purchases with no limit to support markets
The most recent episode of the Neoliberal Podcast covered this in layperson's terms. Despite being pro-helicopter money, they point out that the bureaucracy to do so isn't in place and that there isn't precedent/procedure for FED action of this kind. So for now the FED is using all of the tools it's used to and waiting on congress to act, hopefully with helicopter money but it will be slow even if the current arguments around constraints are resolved.
sf_rob··on Man's 'experiments' with explosives were lawful, court rules
We used to do this in high school and bought a single large bag of potassium nitrate from a local commercial agriculture shop. We even called ahead to make sure that it had specific chemical designations on the bag because it was far enough away to be a pain to get to. Looking back it was very dumb in a legal sense (and a lung health sense haha).
sf_rob··on New flaw in Intel chips lets attackers slip their own data into secure enclave
[Ignorant tangent] Is core hardware more exploited these days or are vulnerabilities just more reported in tech news? I'd assume the former, but I'm not a hardware person. If so is this just due to increasing complexity/optimization going on in chip design or better tooling/methods of exploitation?
sf_rob··on Robinhood goes down again, during another historic trading day
Agree that heads should role, but it may very well be management decisions that brought them to this point. We don't know if engineering was resource/strategically limited (seems unlikely at a well funded startup but it may have been). Having worked places where terminations were the result of failures, it's not always the party most responsible that is let go.
sf_rob··on Stock Futures Were Halted Sunday Night After 5% Drop
Here’s some actual analysis of rolling puts as a hedge: https://movement.capital/the-true-cost-of-hedging-sp-downsid...
sf_rob··on Reddit has become a guide to personal finance
r/financialindependence is the bigger FIRE subreddit
sf_rob··on Google Chrome's fear of Microsoft Edge is revealing its bad side
I agree. While I'm primarily a Firefox user, Edge Beta is the best experience on my Windows machine. I'm surprised that it seems faster than Chrome when they're utilizing the same rendering engine (probably the built-in tracker blocking?).
sf_rob··on Single-payer healthcare would save $450B and 68k lives a year: study
My SO has insurance through/at her med school and has to dispute bills every time she goes in because they bill them as non-covered. Oh and imaging in the same building / under the same hospital wasn't covered. It's crazy that even medical professionals can't get good/clear services.
sf_rob··on Radical hydrogen-boron reactor leapfrogs current nuclear fusion tech?
Tangent, but assuming fusion energy generation will be a reality in the next 30 years, what do you believe the price/KWH will be? I am not knowledgeable enough to parse the estimates I've seen and want to believe in the post-energy-scarcity future.
sf_rob··on Even with a $199 Laptop, Clear Linux Can Offer Superior Performance
I have quite a few more tabs open at any point in time including some large spreadsheets so 8GB tends to be my minimum before I start noticing on Windows/Firefox even with an M2 SSD. Firefox alone is at 4GB for me. This is also my fault for not snoozing/bookmarking aggressively.
sf_rob··on Twitter says an attacker used its API to match usernames to phone numbers
My account was locked, I never sent a single tweet or even followed anyone, just refused to provide them more information about myself.
sf_rob··on The missing semester of CS education
I graduated high in my CS class from a top school, but it turns out that I'm just good at tests/abstract thinking/hacking things together with duct tape. I'm terrible at software engineering, and really glad to see this kind of stuff being emphasized at the university level.
sf_rob··on Alphabet announces fourth quarter and fiscal year 2019 results [pdf]
MS included Office in Azure revenue so it's fairly inflated.
sf_rob··on Tesla Financial Results 2019 Q4
>Worst of all the Bolt's infotainment system is horrible.

It has Carplay/Android Auto; you'd never look at that UI if you didn't want to.

sf_rob··on Tesla Financial Results 2019 Q4
As you mentioned that's marginal profit. You'd have to include estimates of their other costs/liabilities before estimating future market cap.
sf_rob··on Tesla Financial Results 2019 Q4
When buying call options the max loss is the purchase price. There's not a symmetric return as there is with owning stocks directly.

The reason you can make so much with so little capital is that the probability of the stock price moving above strike price of the call option is low assuming that the strike price is much higher than the current price and the expiration date is soon

sf_rob··on Tesla races past $100B in market valuation
I'd add shorting is expensive (borrowing fees or volatility premium on options) and more complex (margin/option approval etc). Plus the old adage that the market can remain irrational longer than you can remain solvent.
sf_rob··on IRS budget cuts cost $34.3B in lost revenue from big business
This is the broken window fallacy. If our goal is to increase employment rates then we should support policies that do so where human productivity is most efficient.
sf_rob··on Google Will Soon Let Users Automatically Scrub Location and Web History
I'll chime in here (like I do in all these threads until it's fixed) but Google Home and Android Auto require all of these settings to be enabled last time I checked.
sf_rob··on Ford to put $500M into electric vehicle startup Rivian
I'm really curious how their upcoming PHEV F150 does. It is planned to act as a 110v AC generator for job-sites, which is a really cool application.
sf_rob··on Beyond Meat S-1
If they find this compelling then I have some Doterra to heal their telomeres.
sf_rob··on Beyond Meat S-1
The vast majority of meat is not 100% grazed. You have a point, but it's largely a theoretical one. If one can find a source of meat that is 100% naturally grazed then they could probably go through similar effort to eat non-meat products produced in minimally destructive ways.
sf_rob··on Its butterfly keyboard design has failed, but Apple has yet to admit its mistake
I damaged my company 2017 MBP by dropping it ~24" when I caught the cord on my foot. The Genius Bar wanted me to pre-authorize $800 of charges before they would even look at it. I was a bit appalled that I couldn't pay any kind of diagnostic fee.
sf_rob··on The Healing Power of Gardens
I come to gardening with the same attitude. Basically if it doesn't grow well in my temperate climate then I just grow something else next year. Tomatoes, mint, and squash all grow like weeds and are super easy, peppers are finicky, and leafy greens are a battle against aphids.

That said, I know plenty of other hobby gardeners who treat their gardens as an exercise in optimization. Heck, I even know one engineer with a grid of (legal) marijuana plants who varies the nutrient composition of the soil in each planter to play with his quality/yield.

sf_rob··on Chinese tech firms are throwing out applicants over the age of 30
Wow, I've received frighteningly little interviewer training, but the "things to not say/consider" talking point has been reiterated strongly. That said, I can't say I'm surprised.
sf_rob··on The Weird World of Vegan YouTube Stars
Ah yes, I'm showing my US bias :). I was just surprised to learn this from a (US) doctor friend!
sf_rob··on The Weird World of Vegan YouTube Stars
MDs get very little instruction on nutrition FWIW, although they would be helpful in terms of longitudinal monitoring.
sf_rob··on Yield Curve Is More Inverted Than at This Point in Run-Up to Financial Crisis
You'll only be able to refinance if a bank is willing. If a recession is the driver of a fed rate reduction, that seems less plausible.
