CyanLite2··on ‘Things are going to break’: Texas power plants are running nonstop
That's DC power not AC needed to power homes, and even then only 2 minor junction points.

The power plants and substations are still needed to act as a giant DC-to-AC inverter. So if the plants are offline then the grid is effectively down, as it was in the Feb 2021 blizzard.

CyanLite2··on Microsoft begins “Extinguish” phase of dealing with Open Source
Did anybody actually read the article? It is clear FUD.

It's just a minor policy change on the Microsoft Store which says you can't create an "app" for a free open source product as if it's your own. So, you can't create an app of Ubuntu Linux and charge $5 for every download on the Microsoft Store.

Reasonable. Sound.

CyanLite2··on Wasting time in tech interviews
I think OP is saying that 99.9999% of the other companies aren't FAANG even though they pretend to be. Their use case is displaying JPG images, not creating a new JPG algorithm. You don't need multi-dimensional array manipulation leetcode hard problems to do that. Yet their interview process is geared around that, and the recruiters/management don't know enough to know to make a useful decision. And then everybody complains "Oh, we can't find competent talent. Give us more visa openings!". But the free market eventually is taking care of those companies. You're seeing major layoffs in the crypto industry because they overhired on leetcoders and apparently not enough people who could help them turn a profit.
CyanLite2··on US Supreme Court Overturns Roe vs. Wade [pdf]
Clarence Thomas said the quiet part out loud. He publicly challenged anyone to send them a case on gay marriage or birth control and they would happily oblige and overturn those rulings as well.
CyanLite2··on It's Good to Bet on .NET
use the free VSCode. Or pay the $7 a month and use JetBrain's Rider (which is quickly rivaling Visual Studio in terms of productivity)
CyanLite2··on US Navy wirelessly beams 1.6 kW of power a kilometer using microwaves
Yea, seems like easier technology is out there for real battle zones. I think this wireless power idea would be best in disaster scenario areas on the US mainland after weather events.

They could pre-ship out the dishes to EMA agencies around the country. Quickly deploy in a few hours and re-power areas that have been destroyed by hurricanes/tornadoes/wildfires until the electrical grid is re-established or a ISO container can be sent.

CyanLite2··on Where in the galaxy will we mine lithium?
Wouldn't it be easier just to smash hydrogen atoms into helium atoms to produce Lithium?

Nuclear fusion seems much more achievable than interstellar space travel.

CyanLite2··on Ask HN: Shouldn't we be turning an eye to power consumption?
Nope, still does AC-to-DC conversion
CyanLite2··on Ask HN: Shouldn't we be turning an eye to power consumption?
Those outlets have an internal AC-DC converter in them.

I can't find the link/product, but Matt Reiseinger (youtube superstar home builder) showcased a distribution box where he ran USB-like cables in the bedroom/living areas. There was a main DC distribution box that delivered power to those places. You could plug in a standard Macbook Pro USB-C cable directly into the wall and get DC power. No conversion (except what was done by the distribution box). The AC-DC converter in the distribution box could be directly bypassed if you were running on solar/battery/wind sources.

CyanLite2··on Ask HN: Shouldn't we be turning an eye to power consumption?
You're probably off by an order of magnitude. But your point is valid nonetheless.

Average Tesla can do nearly 300 miles per charge. A gallon of gas can do about 30 miles per gallon in a similar sedan.

CyanLite2··on Ask HN: Shouldn't we be turning an eye to power consumption?
I think an easier answer for all of this with a more direct impact to consumers wallets and carbon consumption is to use more DC wiring inside homes.

Those big ugly power supply bricks that we all carry around for our laptops... it converts AC power to DC power that's used by your device. Your cell phone adapter, your Xbox/PS5, etc..etc.. Nearly every one of our electronic devices require converting AC input to DC so you can plug into a standard wall outlet.

You can expect about a 5-20% on average power loss just to do the conversion. With alternative energies coming online from DC sources, the power loss is starting to get pretty bad.

DC Input (solar/wind) -> High-Voltage AC (for transmission lines) -> Low-Voltage AC (240v coming into your home) -> Power Brick -> DC Output (just so you can charge your phone).

5-20% power loss each time that's converted just to pull 5 volts @ 3 amps just to charge a cell phone.

CyanLite2··on Evaluating Graviton 2 for data-intensive applications: Arm vs. Intel comparison
cliff notes?

CyanLite2··on Latvia wants permanent U.S. troops, foreign minister tells Blinken
Who's going to pay for all of this?
CyanLite2··on Ask HN: Should HN require/encourage job postings to have a salary range?
Yes. Next question?
CyanLite2··on Slack is down for some users
The desktop app is Electron, or something similar.
CyanLite2··on Amazon more than doubles max base pay to $350k
You work there 3 years and you'll earn a million bucks. Plenty of life to live after that and a lot of money to do whatever it is you want. Many people are willing to make that tradeoff, perhaps not you though.
CyanLite2··on Amazon more than doubles max base pay to $350k
It's a start. Many other companies haven't gotten the weird idea that people like to be paid more money or they go elsewhere to find more money.

At the end of the day, it's a job. And jobs that pay the most usually recruits the best.

If they're looking at $350k base salary plus incentives, I may give them another look, especially if I can still do WFH.

That and going all-in on Hashicorp.
CyanLite2··on Grocery store shortages are back
Sounds like there's going to be a glut of over-production in March.
CyanLite2··on Ask HN: Why is there a chip shortage?
Tesla, for the most part, is skipping that validation and just shipping cars. The warranty issues from Tesla have been notorious, but their business model is to ship cars as fast as possible and deal with warranty issues later. They were able to side-step much of the chip supply issues by either shipping cars without certain features (no adjustable seats, no USB-C ports, etc.) and also switching to newer 7nm+ parts, like the AMD Ryzen x86 chips that they've started shipping in the past few weeks. Their direct sales model allows them to easily change the price on the website, and so far, they still have unbelievable demand.
CyanLite2··on There's been a big rise in monitoring workers at home
Big legal issues for the video/audio monitoring. That's essentially wiretapping. Also other data privacy issue if your housemate also works from home in an industry like financial or healthcare and has to routinely discuss customer/patient information.
CyanLite2··on Former Ubiquiti employee charged with stealing data and extorting company
Police often give the line, "It'll go better for you if you just tell me the truth now" or "You'll get a better deal if we don't get lawyers involved". This often spooks people into cooperating without lawyers and they end up taking the first deal they get. I'd like see some real legal experts weigh in on the legality of these pre-lawyer offers.
CyanLite2··on Electric vehicles could fully recharge in 5 minutes with new cable design
Two of the biggest crypto miners are in Texas, where (until very recently) power was essentially free at night. The winter storm this past February changed the economics a little bit, but for the most part, the Texas Power Grid creates more power than can be consumed at night. And supposedly if the power grid (ERCOT) has enough consumption, they will pay the miners to shut down.
CyanLite2··on Lead time for new Intel NIC orders is quoted around 52 weeks
Informed people care about freedoms as much as you do. But all the conspiracy theory junk about ivermectin, lizard people, and microchipping in the vaccine is the modern day equivalent of yelling 'fire!' in a crowded theater.
CyanLite2··on Microsoft and an army of tiny telecoms are part of a plan to wire rural America
So much apparent bias in this article (from telecom vendors).

>Bowles says a fiber-to-the-home alternative would’ve cost $5.5 million, taken at least four months longer to construct, and covered just over 600 homes.

This is the problem. If it was a wealthy neighborhood, no one would blink an eye at spending $5.5 million of government funding to string fiber to 600+ homes. But if it's rural people, especially the black or brown ones, then it's a questionable decision, and they should just get shoddy CBRS-based Internet instead at a $2m cost instead.

CyanLite2··on It's tough being an Azure fan
Am I the only one who thinks it's incredibly suspicious that the folks that "discovered" the Azure security issues were the same guys who were responsible for Cloud Security at Azure? https://www.wiz.io/press-releases/wiz-emerges-from-stealth-w...
CyanLite2··on The Big Escape: How the Ultra-Wealthy Avoid Paying Taxes and How to Fix It [pdf]
The rich invest in hard assets that produce income. Whether that's dividend from stocks, or rental income from commercial buildings. That recurring income is usually enough to service the loan.

And remember the ultra-rich themselves own the bank. Warren Buffet has huge multi-billion dollar positions in Goldman Sachs and Wells Fargo, in addition to owning the real-estate arm of Berkshire Hathaway itself. And the ones that don't own the banks, still get favorable personal treatment from banks in order to get their M&A or underwriting business.

CyanLite2··on The Big Escape: How the Ultra-Wealthy Avoid Paying Taxes and How to Fix It [pdf]
Ultra-Wealthy secured loans don't work like mortgages you and I deal with. On a $1 billion dollar asset, they can borrow like 40% of that, with no monthly payments, just one big balloon payment at the end of the 10+ year term with a little bit of accrued interest. They simply refinance in 10 years, and now the asset is worth $3 billion and then they take out an even bigger loan. Because it's a loan, it's not considered taxable income. And the interest payments on this loan are tax deductible. And usually these assets (like real estate, or stocks) often pay out dividends or rental income. So they can borrow on these assets ad infinitum and use the proceeds to continue to reinvest in more hard assets and to fund their lavish lifestyle. They won't directly own a super-yacht, their company will own it and rent it back to them, with the maintenance expenses considered business expenses since it's a rental business. Same with their vacation houses. Along the way they may pay a modicum of capital gains taxes on the stock dividends, but it's usually offset by the tax-deductible interest on the loan itself. Rinse and repeat for a few decades.

At the end of it all, they have enough dividends/rental income, that's paying for lavish lifestyles, and they still own all of the hard assets that they can then pass down to their heirs with minimal taxable events.

CyanLite2··on Microsoft Azure silently install management agents with vulns on your Linux VMs
The basic firewall (Network Security Groups) blocks network access by default. So you have to grant the attacker access to the port and IP.
CyanLite2··on Vaccine experts: Covid-19 booster shots aren't needed now
It's to flatten the curve. Approx 10% of vaccinated still require oxygen and other medical measures. And with hospitals currently at full capacity, boosters are a short-term way to keep the hospitalization numbers low until kids can get vaccinated and every one else has had their chance before we fully open everything up once and for all.
