Yep, for decades. They used to be much larger consuming the space of a large table. Now they are small units like this:

Just search for “surface mount rework” or the nickname “hot air pencil”.

I always thought the “fix” to a traditional soldiering iron was a hot air pencil.

“To understand recursion, you must first understand recursion.”

In modern parlance, this has been my working understanding too:

But yeah since computing came along disk has also been used more for magnetic media (hard disk) while disc has been used more for optical media (compact disc).

Optical:

• compact disc
• laser disc

Magnetic:

• 3.5" diskette
• 800GB hard disk drive

…and just to point out there is some disagreement

Magneto-Optical , such as Sony MiniDisc, is sometimes referred to Disc for its optical properties and sometimes as a MO Disk for its magnetic properties.

Only 4% of marketers overall think X ads provide “brand safety” — certainty that their ads won’t appear alongside extreme content —

The 4% may represent lumpy pillow manufacturers, sellers of freeze dried survival food, random cryptocurrency products, and Trump 2024 flag/tshirt providers.

The spokesperson added that X’s “brand safety rate is on average 99%, as validated by DoubleVerify and Integral Ad Science,” companies that analyze the value of digital advertising placements.

“But that 1% remaining will have your products featured next to ads denying the holocaust, hate speech against LGBTQ+ communities, and ads discrediting proven science in favor of, oh I don’t know, phrenology or something” -the spokesperson probably

I thought exactly the same thing. If they’re not a 3D printed rocket company then they’re just another of a field of rocket companies? Why would a customer choose them. The article enlightened me to who:

In a private letter to “investors, advisors, and friends” summarizing the company’s operations after the first half of 2024, Relativity said it currently has a backlog of $2.6 billion in commercial launches and is in discussion or has signed a contract with many major megaconstellation providers (but not SpaceX). Ellis would not confirm this, but multiple people have told Ars that Relativity recently signed a deal for multiple launches with Amazon’s Project Kuiper constellation.

There is at least $2.6 billion worth of customer that wants a SpaceX like launch product, but is unwilling to buy from an Elon Musk company. With how toxic Musk’s behavior is these days, I could see that customer market growing. The US government is putting LOTS of payloads into orbit in SpaceX’s Falcon 9 because there’s nothing even close to it in price and performance. If Relativity can even get close to Falcon 9, they’ll almost certainly pick up a large chunk of US payload contracts as the government doesn’t like to have a single supplier for nation security reasons.

Finally a way to experience the “center fold” in the original authentic format.

To people joining this thread later asking where a commercial product of this is, or pointing out that 10% solar efficiency is way below other existing products, you’re missing the point.

This is basic research to prove one single aspect of solar panel construction. That question apparently was: “We currently know that PET backsheets work for solar panels, but can we use a different material which may have less CO2 impact and still produce a working solar panel?” The answer being “yes”. That is a big step that other people doing other research and product development can build on. It may be years (or never!) that a product comes to market with sisal fiber backsheets, but the answers from the work done here are integrated into the body of knowledge that will produce the next improvement in solar panels.

twelve fingers and three tits.

I can’t tell if that was generated with a weak and lazy prompt or an incredibly detailed prompt asking for that exact configuration.

They lose points for not fully adopting mixer tap technology.

Here’s another one: In the last 10 years the UK has made the largest change in time freight waits to enter the nation.

It’s soo ridiculous the hoops a person would go through to avoid a slight bitter taste.

I figured out a fix for the avoidance of horrible tasting medicine:

The simplest and easiest way to use it is with an ice cube or two. Get the pill/liquid medicine you have to get down your throat ready, your ice cubes, a cup of water and stand in front of a sink. Put the ice in your mouth and let it sit on your tongue for 15 to 60 seconds. Yes, its going to be cold and slightly uncomfortable. The longer you can stand it the better your result. After this time has passed with the ice in your mouth your tongue will be numb. Spit out the ice in the sink, you’ll have 5-15 seconds where you can’t taste a goddamn thing which is plenty of time. At this point you could put the most disgusting flavored thing (sour, bitter, etc) and you won’t be able to taste it. Quickly get the medicine in your mouth and chug that full glass of water. Taste will start to return within about 3 or 5 seconds of chugging water, so make sure you drink enough to clear your mouth of whatever bad flavor you’re trying to avoid.

This whole process adds perhaps 2 minutes tops to taking medicine. For those that have difficulty this is a tiny fraction of time usually spent avoiding taking it, or the recovery process for taking it normally.

If you need more incentive (especially for kids) instead of using ice cubes and spitting that out. You can use ice cream or milk shakes and just swallow those. Same rules apply: put the ice cream in your mouth and let it sit on your tongue as long as its frozen. Its a little more involved than ice cubes because you might have to have two or three spoonfuls to get your tongue numb.

California announces that the policy is going to expire. People who paid more and had an expectation of never-ending special road access are angry.

This is the step where your comparison to solar (at least in California) breaks down. I’m not a California resident, but from what I understand under the NEM 1 and NEM 2 rules there is NO expectation the preferential net metering will last forever. Solar customers were specifically told that putting in solar during NEM 1 would guarantee those terms for 20 years from install date. Same thing for NEM 2, the rules would apply for 20 years from the install date. After the 20 year period, you’d be subject to whatever net meter would be offered to new customers, which could be none. source

What this proposition proposes is cutting that 20 years to 10 years from install date:

"Convert NEM 1.0 and 2.0 accounts to the NBT either upon sale of a home or after 10 years of interconnection. " source

So customers that took a large financial risk installing solar that are coming out ahead may now have the deal shifted out of their favor. How is that fair to the solar customers? Worse, the knock on effect will destroy the trust in state government incentives in the future. Why would any citizen risk a long term outlay based on policy if the state government may decide one day they don’t want to hold up their end of the deal anymore?

I’ll be the first to say de-carbonizing a home isn’t cheap to do (or the home ownership for that matter). I’m doing what I can by buying and implementing the de-carbonized solutions today to increase market demands driving the technology and solutions lower for everyone else.

I’m in Utah, and people here push back against nuclear, but we literally live next to a massive desert. Nobody cares if we dig a big hole in W. Utah or E. Nevada, we can bury it however deep we need and it’s not going to impact the water table at all (we don’t really have a water table here anyway…)

If you don’t have water nearby, you’re not going to be able to use nuclear power in any utility grade scale there.

Which is why hydrogen is so interesting to me, especially solar-generated hydrogen. It’s a pain to store, but if it’s used relatively quickly, the losses should be small enough to make it worthwhile.

The pain with hydrogen storage isn’t just leakage (which is a huge problem because of how small the molecule is), but energy density. Gaseous hydrogen needs either extremely large containers or really extreme pressures (meaning thick, heavy, expensive) and even then its not very much energy storage. To get even higher density requires liquification, which means which is only reached at −253°C (−423°F), and that also requires large expensive machinery and energy to run it.

Unless you’re changing hydrogen into something else (like ammonia), hydrogen isn’t a great solution for energy storage or transportation.

We put in 10kwh of batteries in Feb of this year with our solar panel installation. So I suppose I might be part that headline’s statistic. April was the last time we had a monthly electrical bill. Last month we ripped out our aging gas furnace and put in a cold climate heat pump. One week after we had the natural gas disconnected permanently from the house. Our cars are charged on sunlight. We’re doing what we can do de-carbonize.

Gone in favor of a less useful interface Powershell commands. Fantastic!

I remember when I was growing up, tech industry has so many people that were admirable

Perhaps you were too young to understand who these people were:

• Bill Gates dominated the PC world with aggressive business tactics and vendor lock in.
• Larry Ellison bought up his competitors and jack up prices on databsae products owning the industry for more than a decade.
• Steve Jobs lied and cheated his investors, his family, and his closest friends to benefit himself.

Tom was a good guy, but possibly because he took his fortune and left tech. There were very few admirable leaders.
