This is silly. Energy and momentum are preserved. m g h = 1/2 m v² is tested over and over again in ballistics experiments in intro physics labs. https://www.youtube.com/watch?v=QkzbLMQMFck . A wrong factor of 2 would stand out.

> it hides the ease with which we can derive E = mc² from classical physics without using Einstein’s relativity

Einstein's full equation is:

E² = (p c)² + (mc²)²

The (p c) term is the kinetic energy term comparable to Young's "product of the momentum and velocity" (quoting Young), not the mc² rest-mass term.

> E = mc² is the maximum kinetic energy a particle can have.

Thus setting an upper limit to the speed any non-massless particle might have (and incidentally disproving special relativity).

The Large Hadron Collider runs at 6.5 TeV per proton - https://en.wikipedia.org/wiki/Large_Hadron_Collider .

The proton has a rest mass of 938.3 MeV/c² - https://en.wikipedia.org/wiki/Proton .

The 6.5 TeV of kinetic energy is some 7,000 times larger than the supposed maximum of 938.3 MeV.

Ergo, this quoted 'maximum kinetic energy' claim is wrong.

> The original derivation of kinetic energy in 1807 by British physicist Thomas Young was correct and should not have been changed

Young didn't derive kinetic energy in "A course of lectures on natural philosophy and the mechanical arts", he defined energy as "the product of the mass or weight of a body, into the square of the number expressing its velocity." Page 78 of "A course of lectures on natural philosophy and the mechanical arts" at https://archive.org/details/lecturescourseof01younrich/page/... .

While he points out that doubling the speed of a dropped object requires four times the height, I wasn't able to find where he calculates potential energy and makes the equivalence between K.E. and P.E.

Dota has an interesting approach. They collect tons of statistics, but ultimately the game design comes down to one person, and they complement the stats with a lot of interviews with top ranked players to get their subjective perspective.

The end result is the game has gotten better balanced continuously with time. There were a handful of patches that were a regression, but usually are on top of it pretty fast.

One of the more pernicious problems they've faced is the team that holds the base on the bottom half of the map has consistently had an advantage, as much as 5%. This appears to be related to the perspective being 3d in the shape of top down, vs a literal 2d top down view. They've tried a few different ways to balance this, but what's ended up working best is trading it off vs first pick in the lineup drafting phase of the game start.

Zynga was infamous for a stats driven approach, but there it was all about tricking people into maxing out the micro transactions :(
But that applies to anywhere though. As a man you can sit alone in a bar and nobody will bother you, as a woman lots of people will come up and start to speak with you and possibly get angry if you don't want to speak with them. The fact that the same happens in games isn't evidence that there is something particularly wrong about gamers, rather it is the exact same social game that happens in all leisure spaces.

Of course it would be better if women didn't have to deal with it, but you can't just blame this on gamers since men everywhere does the same thing.
Yeah we have fixed usage so scaling or easy failover is not something we need.
You and I certainly do not need to see any more Coca-Cola advertisements to remember that the brand exists when we are choosing what drink to buy. But there are hundreds of thousands of people born every day. If Coca-Cola stops advertising it may not impact their sales for years, but eventually they could fade away.
> How often are you going on road trips?

Over the last 18 months or so, between remote work and lockdown, journeys of 350+ miles with minimal stops (< 30 minutes total) probably make up about ¾ of the trips and 90%+ of the miles on my vehicle. A typical pre-COVID year would see about half a dozen trips like that (one way) mixed with commuting and trips around town—with the longer trips still making up a majority of the total miles driven. As I see it, at least in my situation, the ability to handle a 350+ mile trip smoothly and efficiently with at most one stop of 30 minutes or less is a basic requirement for any vehicle I would be willing to consider. Anything short of that would be a significant downgrade in practical terms from my current vehicle—an inexpensive, decade-old non-hybrid Honda Fit Sport which still manages 35 MPG on the highway.

Ecologically speaking, if I'm not using the EV for these longer trips then the environmental benefit of switching would be practically nil. Most of the miles driven would still be in a gas-burning vehicle. The same goes for a PHEV. We need to acknowledge that the shorter range and longer "refueling" times of EVs are significant practical issues standing in the way of EV adoption, and not ignore or downplay them. Fortunately we're finally starting to see some pure EVs with the necessary range, and also making some progress on building out suitable charging infrastructure. Now if we could just address the proliferation of brand-specific and member-only charging networks…

The ketchup industry stopped advertising, and over the next 50 years their market share went down. Nobody knows for sure how much was stopping advertising, but nobody wants to take a chance.
Also Tesla does not 'need' to advertise, yet.

It is effectively advertised by everyone for Elon for near 0 dollars. Launch a rocket (different company) the article will mention Tesla for them. Talk about saving the environment guess who gets mentioned. Talk about power needs, Tesla comes up as cars are becoming a large consumer of electricity, solar, coal, nuke, etc.

His advertising is basically being done for free by companies who do not even really realize it.

I mean, Germany is not void of issues, or the UK, where I currently reside, or any other country really...

But comparing my example with the NSU makes no sense to me, the NSU is comparable with Aum Shinrikyo (the Japanese cult that caused the sarin attack back in the 90s) in the sense that they both have/had negligible memberships compared to the countries population, i.e., a few hundreds or couple thousands members, so I don't think in either case you can generalise the behaviour of German or Japanese citizens from the existence of 100 or 1000 pieces of shit human beings.

Japan's immigration percentage is also massively different (~2%) from that of Germany, Spain, UK, or USA (each ~15%) and I'm sure that has an impact on the attitude towards foreigners too.

I completely agree though that the issues I may run into in Japan are probably going to be different and possibly less severe than those that eastern/southeastern asian people or dark-skinned people may face.

Contrast that with the quote from the article:

"Shares in Tencent plunged 9.0% in Hong Kong on Tuesday amid widespread market jitters over Chinese regulatory crackdowns on high-growth sectors, including online platforms and, most recently, private tutoring. Hong Kong's benchmark Hang Seng Index (.HSI) fell 4.2%."

The stock price may not correlate with short-term budgets, but it absolutely has an impact on long-term budgets. So what the investors will be asking themselves now is: "Is this disruption just a short blip on the radar, or did we just witness a long-term change of the Big Tech landscape in China?" Getting on the shit list of the Chinese government sounds like a long-term problem to me.

That would turn off a lot of buyers because it would bring undue attention. Buyers may not know the exact origin of stuff they're buying. A car for instance could formerly have belonged to a person you might not want to run into. A public record of that purchase however would make it a possible target not just for the original owner, but also any rivals he/she may have.
>The experience was not that my program became more safe in the sense that I could ship it without sweat on my brow. No, it was that it just worked, and I could completely skip the entire debugging process that is core to the development experience of Julia, because I had gotten all the errors at compile time.

>And this was for small scripts. I can only imagine the productivity boots that static analysis gives you for larger projects when you can safely refactor, because you know immediately if you do something wrong.

Getting the program right the first time can't _possibly_ apply to programs larger than a small script. Type errors are only 2% of all bugs in large programs with companies behind them. When a big Rust program fails, then you have to contend with the fact that you can't even set a debugger checkpoint where an error occurs:

https://github.com/rust-lang/rust/issues/54144

Obviously people wouldn't be asking for that if the type and borrow checkers caught all the bugs at compile time. Not even close!

And not only can't you debug errors, you also can't change the program at all. All you can do is terminate the program, generate a new one from modified source code, and run the new program. I hope that bug you were working on is simple enough that you can reproduce it with a unit test!

LOL Rust problems!

Now if only Rust had resumable exception handling, could be incrementally compiled, allowed function and type redefinitions at runtime, and wasn't designed as if we were still in the punched card era but with files instead of cards. That would give you far more of a productivity boost than a type checker.

Not a new release, but I've been enjoying Supreme Commander 2 on a modern gaming PC! The game is pretty cheap on Steam ($13)[1] but it scales very well with modern hardware, and the gameplay is far improved (IMHO) over SC1.

I can't see the whole article, but if they don't mention advertising for brand recognition then they are missing half the puzzle (i.e. indirect effectiveness, which is almost impossible to measure).

Coca Cola doesn't shower 16-25 year males with ads because they think they'll walk out the door and go buy a can of Coke. They do it because when they have discretionary income (age 22+), they recognize the brand. This is impossible to measure precisely.

That is false. It is impossible to measure exactly, but statistics can put a range on it, confidence intervals, and other such things (which I've mostly forgotten since school). We can measure all this to close enough.
There's always a logical fallacy in this sort of argument-

a) There are loads of extremely specific laws for various very specific problems. e.g. Taking obsidian from an obsidian flow federal park, for instance.

b) Ergo everyone commits crimes!. We're all criminals, they just selectively choose what to enforce!

b) doesn't follow at all. The vast majority of people will never even be in a situation where it was possible to commit the overwhelming bulk of laws on the book. And that never would regardless.

FWIW, criminals think everyone is a criminal. Tax evaders think it's just normal. Thieves think everyone steals. Etc.

We've been using Sleuth at LaunchDarkly as a single pane of glass for all changes going out into production. The addition of DORA metrics is exciting-- as an engineering leader, Accelerate (https://itrevolution.com/accelerate-book/) is one of the few books I've read where the practices described meet reality. Having a tool track those metrics is a welcome addition.

One thing I'm curious about is Sleuth's approach to the "garbage in, garbage out" problem-- if I'm tracking (e.g.) MTTR, I've found that our teams aren't always perfect about tracking the start / end times of an incident. If the data's incorrect, can I modify it in manually?

The balance sheet is typically abbreviated as BS, so a BS account is a balance sheet account.

It's been a while since I've had anything to do with goodwill, but if I remember correctly it's most commonly the difference in the assets net market value and the purchase price of a company. So if company A buys company B, which has assets of $50 for $100, then they'll add $50 in goodwill to account for the difference.

This is, of course, a simplification as I'm sure goodwill is regulated under GAAP/IFRS. But it does mean that you can't use goodwill to accurately estimate the effects of brand advertising as there could reasons other than brand marketing for a company being traded above its assets' fair market value at the time of the sale.

Yep, we're a small server (~2700) that just randomly had it turned on. We've currently got about 10, just from random members thinking to test if they can create them. 10 that we can't delete. Thankfully nobody has tried to abuse it by naming any anything offensive, or mass creating them yet. Hopefully they won't before the admin gets back on when he wakes up.
We hit a few various issues. One of the worst was the instances becoming totally unavailable for random periods of time, and not being able to do anything really to debug or adjust them. We hacked some code to be able to eventually get into a shell on the machine, but that still didn't give us a ton of control.

Generally we've found that having basic control over the hosting infrastructure is important. We still depend on Azure's LB's and other infra for keeping things available, but having the actual instances our code are running on accessible makes a lot of things easier.

"we completed an assessment of the useful lives of our servers and network equipment and adjusted the estimated useful life of our servers from three years to four years and the estimated useful life of certain network equipment from three years to five years. This change in accounting estimate was effective beginning in fiscal year 2021 and the effect was a reduction in depreciation expense of $721 million and $1.6 billion and an increase in net income of $561 million and $1.2 billion, or $0.84 and $1.81 per basic and $0.83 and $1.78 per diluted share, for the three and six months ended June 30, 2021, respectively."

Think of this way:
You have $2 profit. You can take it paying 0.4 in taxes, leaving 1.6 after taxes.

OR

You have $2, reinvest an extra $1 on marketing with 80% return.
You now have 1.8 total profit. You pay 0.36 in taxes, leaving 1.46

You will always loose money if the marketing ROI is less than 100%

This is a great point, and the authors don't take it into account. Expensing advertising certainly provides tax shield and it will make a significant difference at the margin.

Edit: The taxation become relevant while considering expensing vs capitalizing advertising. I am not an accountant but from what I understand, at least in the US, advertising is commonly expensed.

XMPP failed for normal users. When I switched to matrix years ago it was because the XMPP ecosystem was totally inconsistent. The best client was on android but no desktop clients integrated properly with it (send files, encryption, roaming) especially across multi OSs. I moved to matrix in the early days and all those problems went way.

"Boring" utilitarian cars have gotten much, much better over time, and can easily match acceleration times of previous "pony" cars of the 90s and earlier — cars that were once considered fast, sporty, and fun to drive.

They can do it while being much larger and achieving much better MPG, as well as being a lot safer.

Utilitarian electric vehicles are even better, but not quite commonplace yet.
The "financial crimes" seem to have no victims since none of his investors actually sued him. If he really defrauded them, as the government claims in their successful lawsuit and conviction, then I'm pretty sure they would have sued him also. Why haven't his allegedly defrauded investors sued him?

BTW, let me quote one of his investors, Lindsay Rosenwald:

Rosenwald testified that in 2012, Shkreli told him he was winding down MSMB Capital. And Shkreli offered Rosenwald the opportunity to roll over what Shkreli purported was by then Rosenwald’s $200,000 stake in MSMB Capital into Retrophin, a new drug company he was creating.

"I was given the option of taking the cash or taking the stock, I wanted the cash, I didn’t get the cash.”

Rosenwald testified that he later, over time, sold off his shares of Retrophin. He said that, taking into account his original stake of $100,000 in MSMB Capital, he did make a profit on those stock sales.

Asked how much, Rosenwald said, “Somewhere between $400,000 and $600,000, I think.”[1]

Another investor "realized a profit of almost $1.3 million after selling Retrophin shares it had acquired as a result of a $125,000 initial investment by that fund, Hassan testified."[2]

In short, Shkreli did lie to his investors because he lost their money in the failed hedge fund. However, when he made another business, he rolled their accounts into shares of that business which actually made them a pretty sizable profit.

I guess in this Cancel Culture era, the pious feel justified in the destruction of anybody they don't like.
