Serious question, how would we charge these new high density batteries? Just to charge our current EV's, we need to run dedicated circuits at max capacity and it still takes a couple hours. Are we going be running 1000v circuits in our homes? How do we upgrade the local grids to have this amperage in each home? I'm not an EE, but are our current batteries just poor at "absorbing" this energy while our chargers just waste tons? While these new solid state batteries will hold it all? There's high power fast chargers, but I want to come home and plug in my car after work.

It just seems like batteries aren't the bottle neck. It's our efficiency to produce and distribute this electricity.

ICE isn't perfect, but it's an extreme dense form of energy and the output of it rotational energy. Which is exactly what our end goal is.

In electricity production we outsource it, then store it. Basically the same concept as winding up a spring loaded toy then letting it go when we want to use it. The spring isn't the source of power, it's just the energy storage. Just because we made the spring bigger and output more doesn't make it more efficient. Simply mean we need to spin it more, and with more energy.

We cannot even make the electric motors more efficient, we already run at 80-90% efficiency. What will we see? 1% more? 2% more?

It really depends where your energy comes from. If your energy comes from dams/solar/wind, those have low impacts and can be an efficient way to "wind up your spring" but they generally aren't extremely reliable and cannot power an entire city of EVs. If your energy is from coal, those are horribly inefficient. They run around 33% efficency [0].

All this electricity needs to transported but the power lines waste power, the charger wastes power, the AC-DC converters waste power, the EV motor wastes power. It's so many little losses outsourced to someone else.

I like the idea of EV. There's many pros, but far too many cons still. And it's not the cars fault. It's already maximizing what it can do with what it can get.

Personally, the battery pack prices are the biggest killer for me. I drive a 90s Toyota pickup. It's been problem free. I've driven it for years. Unless it rots to the ground, I'll never see a surprise bill in 10-20 years saying I need a new battery pack. My motor could entirely fail and it would be a $500 fix. Not to mention, it's entirely recyclable. People will give me money just for the metal.

It seems like EV is a nice option for rich people at the moment but if the majority switch over, the concept really falls on its face.

Although, high capacity cell phone/laptop batteries would be pretty sweet. However, we already have problems with phones being pretty dangerous.

From what I understand gluten intolerance (including Celiac disease) is not at all like allergies where even a small amount of cross contamination can be harmful (or even deadly). Gluten intolerance really needs a solid amount (which many foods provide) to trigger problems, and the worry is really the long-term damage that can be done.

So I think that the "gluten-free" labels on things that obviously would not have gluten in them (e.g.: bottled water) is absolutely about advertisement to people who have been trained to think that "gluten-free" is always a good thing.
I have been in the software industry for 30 years as of this month. I have never had a gap of longer then 6 months and the shortest time with a company was 4 years 8 months and the longest time was 16 years. I have worked on the following technoclogies. Companies range from on of the Big 3 consulting firms to startups. Here are the technologies I have worked on

- C/C++ on Win16/Win32

- Assembly language development with Z80/8051/ARM on embedded microcontrollers

- Java (core java, Servlets, J2EE)

- Ruby on Rails

- NodeJS / Javascript

- Worked with AWS tech (the full stack)

- Relational DB (MsSQL, PostGres, MySql), NoSQL db (MonoDB)

- Coded for Linux/Unix, MacOS, Windows 16/32, PalmOS, iOS

I can provide reference for each of those skillsets form my past colleagues.

You know what - I probably couldn't pass half of the insane coding puzzles these interviewers throw out. Not because I can't solve them, I just don't remember enough of the syntax or library semantics of the top of my head.

At my experience can we just assume that I am a competent coder (maybe not the top 1%, but at least in the top %20) and talk about the job and how I can contribute ? I mean its almost insulting if you ask me to make a linked list/reverse a binary tree or other such nonsense looking over my shoulder me with a time limit.
I just watched this a few weeks ago. It is fantastic. Belafonte was a producer as well as the star. He’s playing a man trying balance being a father and musician with a giant gambling problem. His character is only good at being a musician and failing at everything else. He pairs up with a racist criminal to try and relieve a debt. The movie is firing on all cylinders.

I bought a bunch of his vintage albums afterwards and really enjoy them.
BJJ worked in the early UFCs because the Gracies were among the very few competitors who had participated in MMA matches previously (having trained for Vale Tudo matches). A pure BJJ fighter today would get demolished by anyone training for MMA, but arguably Royce wasn't a pure BJJ fighter at the beginning of the UFC.

On top of that Severn, Frye, and Coleman all came from western wrestling backgrounds and they did pretty well in UFC...
> Over the last few years, Tesla has been investing a lot in cybersecurity and working closely with whitehat hackers. The automaker has been participating in the Pwn2Own hacking competition by offering large prizes and its electric cars for hacking challengers.

Tesla literally paid people 100k to pentest their car so they could fix any bugs/issues found, so that you don't get hacked.

To add to this, I've liked the Room & Board furniture I've purchased as well. It's pretty simple design-wise, but solid wood, American-made (if you care about things like that), and broadly available. But honestly, the nicest piece of furniture I have is something I commissioned a local cabinet maker to make. It was only marginally more expensive than what a comparable piece at R&B would cost, but was completely custom in a way that R&B could not be, and it was also nice to support local woodworkers.

Before using any function of the strcpy family, try to think about why you are using them.

The first question is: do I need a copy? Obviously, often, you do, but maybe you can avoid it. Copying data can be costly in terms of performance, and of course, without copying, no need to allocate memory or deal with buffers sizes.

Now, that you are sure that you indeed need a copy, maybe you should consider using memcpy() instead. If you already know the sizes of your strings, then it is a no-brainer. If you don't, maybe doing strlen()/strnlen() first on your input data is a good idea, and if it is too big, handle the error appropriately, and if it is not, then do a memcpy() now that you have the size.

The default behavior of "safe" variants of strcpy() it to truncate the string to the maximum size. It is certainly better than a buffer overflow, but it may not be what you want, just ask your ass

Errrr. Journalism. Yikes. This happens to be precisely one of the research topics I study, sea ice energy feedbacks and constraints. Two prominent sea ice physicists have gone through the effort to directly debunk this because it's such a bad idea[1]. One is my friend and we talked about it at length. The initial white paper outlining their geoengineering plan has very basic flaws in their physical assumptions and spectral response.

This is an astonishingly bad idea. I'm disappointed in the lack of background+context provided by the New Yorker here...

Depends on how supply performs relative to demand… price is just a function of the balance between these two. Fossil fuel consumption is still growing globally, and faster than production.

So prices currently look set to rise. Higher oil prices make renewables look relatively more attractive though, so its a bit reflexive

Quick math:

When viewed from the moon, the earth's diameter subtends an angle of about 0.033 radians. On the other hand, if the photo was taken from an orbital altitude of 100km, then the lunar horizon is about 600km away from the viewpoint (using Pythagoras' theorem).

So at the horizon, a crater the same apparent size as the earth would be roughly 0.033 * 600 = 20 km across.
UV from sunlight degrades fiberglass/FRP over time. I believe that boats are painted to protect them from this, and need to be recoated periodically because the uv sunlight will degrade the paint eventually, also.
We can support today's amount of industry and consumption on 100% renewable clean energy. (And we'd actually only need half the energy to do it.)
It's a good thought, but the wrong solution.

The US should do what other civilized countries do and send you a tax bill. They can give you a simple form to tell them a few things that a lot of people have (donations, change in marital status, new dependent, other income like rent, etc) and then you can either pay the bill or file the regular return because your situation is complicated.

90% of taxpayers only have income the government already knows about, and with some simple data about donations and dependents, most people's tax bills can be calculated and billed.

The only people who would need to prep forms would have such complicated situations that they need a professional.

> The best way to reduce piracy of copyrighted works is to cut the copyright period by 75% relative to current standards.

Personally, I believe this would have a negligible effect on piracy or even online arguments around copyright. I believe that, because I think the most piracy concerns recent works, e.g., computer games and movies of the last few years.
I said that there is no "talent scarcity" and anyone claiming that there is can count themselves among the rank of bad management. If management can't attract and retain talent, it's by definition bad management.

Generally, a low profit margin amongst the entire industry indicates that business operations are going about as efficiently as possible given current technology and knowledge.

Grocery stores have long had ~2% or even less profit margins. The people working at Costco, Walmart, Kroger, Albertsons, Target, Aldi, Lidl, Tesco, Amazon, etc. are pretty good at what they do, and those managers are not known for getting lavish pay. After all, how could they, since their competition would steal their customers in their extremely price sensitive business.

In general, it's true compared to other metals. Compared to other materials in general (e.g., glass) it's certainly not true.

Semantically our data model is an infinitely nested hierarchical tree of lists, although the UI might not look or feel like "just a list".

Our editor is more like an "outliner" than a traditional word processor, and before January 2022, you could't even select text across multiple blocks. We rebuilt the editor to work like both an outliner and a traditional word processor at the same time. You can still "feel" the tree/list structure when you select and drag multiple blocks around, or use indent/dedent - you can't indent a block multiple times within another block because that doesn't make sense in the tree structure.

I wrote a bit about turning our outliner into a word processor here: https://twitter.com/jitl/status/1483918085384028163

And also about the data model itself here: https://www.notion.so/blog/data-model-behind-notion
As was said by the parent commenter (drewcoo) just before you placed your bet, because no measure is established, each evaluator is bound to have a different opinion of how to measure a developer, and as a result most developers are likely to fall below the median (according to someone's measure).

There is no mathematical contradiction. Perhaps a misunderstanding on your part? Either way, the bet was lost. Time for drewcoo to reap the rewards.
> A lot of managers are both highly paid and truly bad. I think a lot of businesses don’t do as good of a job vetting EM hires as they do SWEs the EM will manage.

From my vantage point as an engineer it also seems like what qualifies as "good management" is hard to pin down because not only is it difficult to quantify in the first place, but it also varies between teams and organizations… a management style that worked in one team and company might fly like a rock elsewhere. If that's true, it'd make vetting managers challenging even if the business in question is trying to vet them as well as they do engineers.

Yep, that sounds about right. O&G being O&G and American politicians being American politicians.

Rant: I'm so sick of the phrase "what the average citizen pays at the pump" and it's relatives. How about making public transport viable? Nope, everyone's got to have big cars and cheap fuel.
Right, it uses other, similar flourosurfactants.
People aren’t divided into “most likely to be tricked” and “least likely to be tricked”.

When you generate “photos” of Big Ben burning and throw it on Twitter, you will grab the attention of many more Londoners than you could with a random image of a burning house or whatever, many of which would at least take the time to verify. Just look at the Balenciaga Pope images.

By grabbing the attention of those you are essentially stepping into the realms of “historical alternations”.

Honestly, I haven't noticed any real difference in Ikea flat-pack vs Walmart Target Wayfair (or even random Amazon listings). It is all mostly cheap junk. If you are willing to pay for the most expensive items, then you start to get real wood, but that's not their bread-and-butter.
Having shopped at Ikea for 20 years now there is one pattern I noticed: In general Ikea won‘t increase the price of an article, instead they would produce it cheaper and cheaper.
I tune out opinions like yours because I know they're extremely unlikely to lead to anything real.
The contrast between your link and the original article are interesting.

The article specifically addresses the point of customer/client expectations in light of the cost, and the response from the guides questioned is "expedition logistics are expensive. You're not buying a lift ticket to the summit, you are paying for food, oxygen, tents, salaries, and insurance. I feel no extra obligation to take you to the summit because you paid more" Granted, that's from someone whose livelihood depends on projecting an air of competence that supersedes any greed.

I became eventually of a mind that certain places must be sacrificial zones to whatever impulse drives people to go to these places. That's not to say that we should abandon Everest to the crowds and the trash and the corpses, but rather that we must develop these places to support the crowds that come. That means building infrastructure like composting toilets and designated camp sites. That means (as Anker proposes in your link) dedicated climbing rangers and climber IDs. That's not to say that every trail should be paved and made accessible to all. But rather that failure to adapt to greater numbers out of concern for "preserving the experience" ultimately destroys what's left of the experience (consider the impact idiots throwing stuff into geysers has had on Yellowstone [0]). It is true that the more developed a place is, the more people want to go there, which is why, when you start down the road to development, you have to over-build it. The upshot is that it will divert people away from areas that cannot support any more interest.
Hum... The morality here is certainly not simple.
Absolutely, this misses the forest for the trees and mistakes a political problem as an economic or technical one.

The problem isn't a lack of FOSS tax prep software. The issue is the need for it, and the cause is Intuit bribing politicians to keep it that way.

I grew up listening to Harry Belafonte at Carnegie Hall on my parent's old record player. He was my first favorite singer and my earliest exposure to folk music’s ability to educate and enlighten. From a young age I understood some of what discrimination must feel like from the characters in his songs, and still know every word to “Darlin’ Cora”. It built a basis of empathy for me to grow from and I’ll forever be thankful.

What an incredible 96 years of art and leadership in the pursuit of civil rights and equality.
All I asked was for you to show why you were saying what you originally said.

Try pricing a 3 year OEM same day replacement warranty for any memory product in your country.

So price it and link it. This isn't difficult, but for some reason you say 'go prove me right' instead of just proving it yourself.

It seems like you'll do anything to not back up what you say. Just link something, link anything to illustrate what you originally said.
>Is the market acting like infinite growth is baked in,

It's this. America has decided that:

1. The most important retirement/wealth vehicle is your home.

2. Home prices must only go up or your wealth will be destroyed.

3. The government should use it's power to uphold (1) and (2), which results in NIMBYism, all the tax breaks you see around mortgages, and of course the 2008 bailouts.

w.r.t stocks I largely think that was a ZIRP phenomenon, but stocks are allowed to correct somewhat.
Something like "Ibn Khaldun cycles" might be a more accurate descriptor with Asabiyyah being the identified driving force. I think the two are pretty close, though the meme is vague enough to allow for a fair bit of projection.

Asabiyyah is strongest in the nomadic phase, and decreases as the civilization advances as the ruling class begins to focus more on maintaining their wealth/power individually at the expense of the group, which covers the Strong Men and Good Times phase. As decadence increases group solidarity decreases Weak men and bad times occurs, which readies the cycle to start anew with additional strong men, which matches with Khaldun's period of 3 generations per cycle.

It's a pretty bare bones social cycle theory by modern standards but the core idea common to both seems to be that history is a cycle of barbarians conquering decadent civilizations, only to eventually become fragmented, self serving and vulnerable themselves at some point. The applicability to the modern world seems to depend on whether the underlying causes have been eliminated, in a "The End of History and the Last Man" sort of sense.
I would love to revisit MM myself, but I don't have the expertise to actually setup the experiment. I might be able to resolve that gap, but I definitely don't have the funding either, and that is a gap I don't know how to solve.
