CyanLite2··on Ask HN: With recent layoffs, how would you advise new grads entering the market?
1. Lower your asking price. The days of 6 figure boot camp grads are over, at least temporarily.

2. Get as much professional experience as possible. There's an entire world outside of the startup/HN crowd where you can thrive in a great career at an enterprise company doing .NET/Java. These are your name brand mega insurance companies or health care organizations that are just trying to get line-of-business apps created for internal use. It's not the brand name cachet as a popular SaaS. These mega corps often don't go out of their way to advertise for new positions, so just checkout linkedin or look at their job boards on their corporate website. These companies often have the large internal development team to pair you with a senior developer and train you up.

3. Bide your time until the market "re-opens". The market will come back, but in the meantime now is the time to build up your CV. If you still are having problems getting a foot in the door, then take on open source projects. Create a side-project. There's nothing worse as a hiring manager seeing a new grad with zero experience asking for $150,000.

BNPL is just a non-asset-backed sub-prime loan. We've seen this movie before and how it ends. BNPL firms can't survive a recession or higher consumer delinquencies.
CyanLite2··on Emergency measures needed to rescue Great Salt Lake from ongoing collapse
Dumb question: could we build a big pipeline from the Pacific Coast and just pump billions (trillions?) of gallons of ocean water to the Great Salt Lake?
CyanLite2··on Ask HN: How do you protect your eyes while coding for long hours?
Blue Blocker lenses.

Also, I get "Plus One". Talk to your eye doctor. They can do "ADD +1.00" to your prescription to make things larger but still in focus. You won't have to hunch forward either.

Then I make all of my IDE font settings larger. I see less on the screen, but I have less eye strain.

CyanLite2··on Ask HN: How do you protect your eyes while coding for long hours?
They work great, but are terrible for video calls as they reflect the light back so your eyeglasses look like "mirrors" to others on the video call.

Is HN doing so bad these days that we now have to link to clickbait YouTube videos?
CyanLite2··on Activision’s faulty anti-cheat software
I'm a stock Xbox Series X console player in DMZ mode. I also sometimes get the random crashes and "DEV ERROR" messages after being removed from the game. I also have been removed from games several times with the "Player kicked" message. I can share my userId with any Activision employee here who's looking into the matter where you can see my K/D ratio is far too poor to be a "cheater".
CyanLite2··on CATL's Sodium-Ion Battery
Same article from Dec of 2020. Lots of promises, but no tangible product.
CyanLite2··on Key staff driving Apple search engine leave to rejoin Google
Sort of the anti-Google.

Whereas Google will release something, get user traction and then try to make it 'best in the world'. If it doesn't get to world class status, then it cancels it and moves on, pissing off the early adopters in the process.

The problem is that this becomes counter-productive just like serial dramas in the TV world. If people think you're going to cancel something, they're not going to get emotionally invested in your product. Then it almost certainly gets canceled because it doesn't get enough user traction. Rinse. Repeat.

The 75% number was a trial balloon to make the real number (50%) less shocking.
CyanLite2··on Ask HN: How do I find my “purpose”?
If you don't yet have a purpose, your purpose is to find your purpose.
CyanLite2··on Ask HN: Examples of Top C# Code?
Follow @davidfowl on Twitter/Github and look at "Minimal API" code for beautiful C# code and examples for specific scenarios.

C# is VERY different from even just what things were 2 years ago. You can now build a full-on app with the same number of lines that a Node/Express/Flask app. Except the .NET runtime is about 5-10x faster than those runtimes.

And this is the problem OP is talking about. Outdated thinking from a 15 years ago is how cargo cults hold onto all the power.
CyanLite2··on Ask HN: 10k hours rule to master anything. Could I switch career when I am 43?
You can do anything you put your mind to. But if you have doubts or not fully committed, then you're more likely to fail.

In other words, just do it. Don't look back. You only have so many years of your life left. Make it worth it.

CyanLite2··on Ask HN: How can I start a business to generate electricity?
The regulations here are prohibitively expensive.

Your state probably has a public service commission that won't allow you to compete with the local power company. Competition in the utilities business is illegal.

CyanLite2··on Ask HN: Are you using .NET to write cross-platform desktop or mobile apps?
Xamarin is now called MAUI. You'll find better search results using the MAUI term.
CyanLite2··on Why is solar more expensive in the U.S. than in other countries?
In the U.S., the National Electric Code requires UL-listed components. The inverters, the panels, wires, even the racking must be UL-listed and not simply "UL tested". The manufacturer has to pay UL a few million dollars to list their products on their database in order to pass inspection. An inverter that costs $500 on Amazon costs about $5000 and available only through certain distributors.

Australia has no such requirement, and so they can use the cheapest inverters from China/Amazon.

>Now that solar panels are trending down in price it seems IMHO the real disruption will be when batteries similarly become cheap enough that homeowners may disconnect completely from the grid or at least make solar the majority of their energy supply.

I think we're there now. You can get "server-rack" LiFePO4 batteries for about $1500 for a 5kWh battery. You can probably get solar, inverters, and 30kWh of batteries for about $25,000 and this should last maybe a few days for most homes. Mini-splits instead of central HVACs reduce power consumption a good bit, and have better energy efficiencies.

CyanLite2··on Solar canopies on parking lots
That already exists. It's called SREC credits. Large corporations pay SREC credits to homeowners and others to reduce carbon. Those credits can be cashed out, and many just use the money to buy more solar panels and batteries.

For one, very sunny places like California are getting very close to the "too much solar" on their energy production. Until microgrids take off, this is going to be a very serious problem in the next 12-24 months. California will probably have one of the lowest kWh/$ rates in the country during summer daylight hours. But off-peak hours will be much more expensive. Adding more solar would not help in these places because it would interfere with the economics of mass power production. The investment to build power plants (nuclear or gas-fired) is too high when you can only run that plant during night-time hours but sit idle during the day. Texas has been in a similar situation, before the Feb 2021 disaster, they were giving away free power at night because of too much wind production. All of that energy production has to go somewhere and grid-scale energy storage isn't feasible just yet. If it's not consumed, then it's just wasted.

Two, the tech is just forming to help solve some things, such as "floatovoltaics". Covering Lake Mead will help, or the Great Salt Lake in Utah. But water is very corrosive. Engineers have also stayed away from putting power lines in water for good reason. The tech for floatovoltaics is just now emerging, and even the national electric code has just put something in it for 2023.

Three, raw materials shortages. Solar requires a lot of silicon, aluminum, glass, and steel. Batteries require a lot of rare earth metals from harmful mining practices. You need billions of tons of copper just to handle the wiring and distribution side of things. Almost all lithium battery and solar manufacturing is overseas in China. There are some in the U.S., but not enough to make a serious dent in solving the overall problem. EV batteries have secured over 140% of the available lithium mines in the world. Alternative batteries like sodium-ion are exclusively produced at scale in China, but startups like Natron Energy are trying to change that (again, not enough to make a dent). But the main point is that there isn't enough lithium, cobalt, nickel, copper, silicon in the world to go around without having some serious inflation and supply chain issues along the way. The tech doesn't yet exist for grid-scale energy storage that doesn't rely on lithium and its closest cousin sodium-ion doesn't have the manufacturing scale to produce the billions of cells annually needed to tackle this problem.

Four, the U.S. lacks political will. Republican states are actively damaging companies who are reducing their carbon emissions. Fox News labels climate change as "woke politics". Thus, you have 40-50% of Americans believing solar panels and EVs as "bad" things. It then trickles down to local politics like where the article shows that Southern states should be accounting for 33% of solar production, but due to poor politics/laws they only account for 7%.

Bad installations make for ugly looks and can ruin the value of the entire neighborhood (who wants to live next to the guy with the odd-shaped panels on his roof?).

In the USA, most HOAs have the ability to place a lien on your house. When you try to sell your property, you have to pay that fine or your house can't be sold. They can also file a lawsuit against you in court which the court can force you to take down whatever objectionable material you have outside your own and/or require you to pay the fine and penalties.

Problem these days are 90% or more of the residential solar sold in the U.S. is only AC-coupled and nowadays only use micro-inverters. Meaning, when the grid goes down your solar is shut down as well. Modern inverters following standard UL1741 also will de-sync from the grid just from a signal from the PowerCo through frequency shifting to shut down your solar and require your house to go in grid-only mode (when the grid has too much solar production).

Isolated DC-coupled solar is mostly done by DIY folks with inverters like Sol-Ark that can do AC or DC-coupling and can work when the grid is shutdown. Your solar constantly charges your batteries and powers your house as a microgrid. Any excess power COULD be sold back to the grid, but to avoid the added hassle of interconnection agreements, most just store it into a larger battery bank for rainy days. The goal here is to fully zero out your monthly power bill AND be self-sustaining.

Easier option is a Reliance Generator Transfer switch. Low-tech, but easy to install and can individually select which circuits are powered via solar or grid.
CyanLite2··on Solar canopies on parking lots
As of February 2022, in the northeast USA alone, there was more than 136GW of backlogged solar capacity awaiting to be connected to the grid. This is the rough equivalent of 80-100 natural gas fired power plants

The power co's have a legal monopoly and in the vast majority of states the commission that regulates these utilities have members that are open bought-and-paid for by the utilities. Thus, they'll never realistically stand a chance unless someone came along with a bigger checkbook. There aren't many companies that want to get into the power business these days that have billions of dollars and the know-how to operate power plants and all the distribution to reach nearly every home.

However, this is ripe for disrupting like Uber did by skirting laws in many areas. Could it possibly be legal to 'provide' power and create a residential subdivision with a microgrid and the price is part of the sale of the house?

CyanLite2··on Ask HN: Why do companies not list your weaknesses in rejection emails?
Just be glad you at least got a rejection letter. Most employers nowadays just ghost people after the final interview process.
