The difference between moving money in your situation and in Apple's, where there's no correspondence between where engineers are located and where IP is licensed from.

By forcing all revenue to go through a single point (the headquarters) it's much harder to establish fake licensing like Apple Ireland's.
> The idea that you can see from somebody’s face what they are feeling is deeply flawed. I don’t think that’s possible.

I agree with most of the article but this point I disagree with. Non verbal communication is a huge component in how we interact with each other.

Covid example: When on calls where no cameras are on I get far less feedback when presenting to a 'room' compared to if I was to present in person or have cams on, even if the room stay silent in both situations.

By looking at faces I can see who is distracted, who looks confused and whether what I am saying is being received well or poorly. Did that joke get smiles (polite or genuine ones?) or eye rolls?

Now - do I think the current SOTA algorithms are at this level of nuance? No, definitely not. But to say it isn't at all possible is ridiculous in my opinion
I publish all my code these days as Open Source.
Nah, IMO. Lots of people have independently invented them, and I would be surprised if Merkle was actually the first.
what time period did you backdate over?

i’m curious what the backdated return would be for different time periods

He said it was a mistake to think the app store review process was good. How is that blaming Samsung?
Linux also doesn't constantly stream telemetry from devices that are being used in a HIPAA-bound setting unlike Windows which is going be sending everything from operational metadata to memory dumps back to Microsoft who will mine, selling and eventually leak it all.
I hear (read) what you’re saying, but I don’t understand the relevance. What does the author’s location have to do with the point she’s making?
I don't know the answer to your question, but that's not how you do this with current over sensitive employees.

Usually you pay a company to take care of your startup social presence and if it happens that the followers are bought, the CEO will say "my bad, did not do enough due diligence on our provider, will fire them effective immediately". All happy.

My greatest wish, now that I am retired and learned a few new things, is that my fellow Americans (I can't speak to other cultures) would stop putting the focus on money. Money and the things it can buy are not that important in the larger scheme of things. If Americans didn't make life a competitive sport, then more would realize this. Near the end, it's all about what you do with time and doing what it takes to remain healthy to live longer and enjoy this time.

When Tesla first introduced the cyber truck they were unsure about the demand and also unsure about the 4680 cell manufacturing. Both of these are now settled. It's not impossible that Tesla will drop the prices substantially when they finally go on sale.
> 2) “The System” can incentivise corporations to maximise transfer of wealth towards the top brass without incentivising it to raise wages any more than only to keep people from leaving.

And they can do that without being exploitative. People go to their bosses and ask for more money. Some percentage of the time they get it.

If you were in business for yourself you would have to negotiate your own prices. Being employed isn't really different, just the risk is much less. You're trading something away for the security of a regular paycheck.
And shorting is not free.
At first I wondered why bother. If there's a famine or a meat shortage, wouldn't people turn to other foods on their own? So it seemed unnecessary and superfluous.

But I suppose there's another possible reason. If you can't give people what they want (meat), give them something else (fish) and try to convince them they do want it. If you can actually pull that off, then maybe it makes you look better and/or makes them feel better.
I don't get it, either. I laugh when schools complain their textbooks are "old and outdated". So what? Has there been a revolution in algebra I didn't hear about?

I also laugh when teachers say they expend all this effort making "lesson plans". There are 3.7 million teachers just in the U.S. You'd think they could share them?
> "Most of the heavy lifting in accessibility is in the ARIA attributes"

Best practice is use to use HTML semantic tags and only add ARIA attributes if it is relevant. For example, HTML5 has a <nav> tag, therefore it is not necessary to add the ARIA attribute "role=navigation". Even the Accessibility section on MDN (Mozilla Developer Network) states: "developers should prefer using the correct semantic HTML element over using ARIA if such an element exists" (Source: https://developer.mozilla.org/en-US/docs/Web/Accessibility/A...)

> "The problem faced by semantic tags is...the information that they carry is of very limited use for a screen reader."

That's precisely why those semantic HTML tags are important - so that screen readers navigate the page more easily (among other reasons).

> "...semantic is just a distraction"

Accessibility is not difficult if you follow HTML5 semantic markup. Compared to CSS, HTML5 semantic tags are easy. If you use HTML5 semantic tags, accessibility comes built-in - you get it for free.

Where accessibility fails is when you're using a JavasScript framework that generates non-semantic markup. Or you're using a CSS framework and your HTML markup is littered with endless <divs> rather than HTML semantic tags.

I recently posted this video playlist of quick accessibility tips for websites (each tip is just 1 minute). Many websites don't follow these best practices. However, I think people might be surprised by how simple and low-effort it is to incorporate these tips into any website.

Apple added requirements for their store to publish extensions, yes. They also added more privacy prompts. If you don’t test on MacOS in Safari, how would you know if your extension works correctly?

Why not ask Apple to release macOS for any computer like Windows on x86? Why not ask for Safari to be published for and API compatible with Windows as on macOS? Why not ask Apple to ship Windows since mac-only APIs would be problematic?

Fact is, Apple requiring a Mac to publish for a Mac-only browser is not a problem. It’s not even true. You can code sign for Mac from Linux[1], as I understand it. Worst case, a third-party service will step in to handle packaging and publishing the way we already do for cross-platform native apps and yet Apple will continue to expect devs to test on their Apple devices.

I can run Firefox or Chrome on my Mac so it’s not like I’m missing out if you choose to not develop an extension for Safari and test it in Safari. I feel like you’re arguing that testing isn’t required if you have the right web standards, which is pretty much always false when there are privacy or other implementation details that vary by browser…

Many books/websites let you view the Latex code, despite not technically being open source. If a website uses MathJax, you can change the renderer to "plain source" by opening the context menu on any math equation. "Paul's Math notes"[1] is a good example, and a really great free website for college-level math.

If you're a screen reader user, the context menu may not open for reasons unknown. Try routing your mouse to the equation and simulate a right mouse click, that should do it. Moving your focus to the equation with the tab key may also be an option. Alternatively, you can just use Voice Over for MacOS, it can do it just fine.
Still is the case. But here they take that job very seriously.

I even saw a higher up personally helping once, I was in an open source tech conference, and a colonel was present to show the air force work using Ubuntu and Debian, while chatting with him he got a phone call about a radar issue, he immediately picked up a laptop and started to fire up some domestic made tech and started helping the operators directly.

If the timing wasn't seemly so random I would think they did it on purpose just to show off the cool tech.
I see prototypal inheritance in communication. When I communicate that I fried an egg you automatically make a number of assumptions about the properties of that event. If we generally hold the same assumptions then I've transmitted the concept with high fidelity.

However, if I believe that your assumptions about the event won't reify the event in a way that mirrors my own then I will want to override your assumption by communicating extra properties about the event. You can dive a bit into this by way of semantics.

For example, the semantic frame 'cooking'[1] lists 'fry' as a member. What are the salient differences between the parent frame 'cooking' and its member 'fry'? A quick way to explore this is by examining the propositional differences between the frame and member roles. You can imagine the differences between the Instrument and Result roles and how their assumptions differ.

How does this relate back to programming? One way to examine programming languages is through their ontological semantics. As much as we write programs for computers, we also write them for other people. Prototypical inheritance mirrors the structure of languages we already find in nature.

I think you nailed it in your last sentence. Hobbies are our chance to create without the baggage of external requirements or external validation.

Being in that creative flow state is the best feeling. If someone else appreciates what you made, that's just the icing on an already tasty cake.

I post my silly art projects on Instagram for 30 or 40 likes. Would I love more? Well, yeah. Endorphins and all that. But I can't stop making this stuff because I just really, really enjoy the moments of making it.
“And best of all, it’s 100% free”
Right. My point is that I'm not convinced that hands-on projects and workshops, when force-fed to students within the context of a course taken at an educational institution, is inherently more effective than any other teaching method. As someone whose career is in software engineering, and who never had much interest in any of the sciences outside software engineering, I certainly remember having to do hands-on projects in required chemistry, biology, and physics courses... not that I remember much, if any, of it at all. The vast majority of true academic learning is self-directed, and the value of experience is in making mistakes that you are forced to bear the consequences of. "Consequences" do not really exist in a classroom (almost by definition), and grades (particularly in an era of grade inflation that renders them largely meaningless) do not count.
Biking in the rain is such a laughable idea to me. I wear glasses, walking in the rain is a pain in the ass as I can't see shit, it would be impossible for me to ride a bike in the rain.

That's just a first order problem for me. Drainage in a lot of city roads is pretty awful so bicyclists have a pretty good chance of getting swamped at intersections or knocked over if a bus or truck sends a wall of rain water their way.

I guess if you don't need glasses and live in the suburbs biking in the rain might not be too terrible. I couldn't imagine it in the city center of any city I've ever been to though.
I don't care about making money in board games. If I did I wouldn't bother, there's not a whole lot of money in there unless you make multiple mega-hits or you one of a handful of publishers, and that's getting harder and harder to do with so many games being put out there every year (I think it's 700+ that debut each year at Gen Con alone).

But I would like to find an audience that enjoys playing my designs, and pretty much the only way to find an audience is to get your game published via Kickstarter or a publisher (there are other methods, like Print and Play and The Game Crafter, but the potential audience is a tiny fraction of other methods, especially since there's already too many board games released every year by publishers to keep up with. I myself have slowed way down in my game acquisitions and the number of games I try every year, I've run out of room in the house and what I do have don't get played enough to warrant keeping anyway).

Otherwise I'm just designing games purely for the hell of it, and I almost might as well be solving Sudoku puzzles or playing Chess instead.

Also despite it being easier to develop and test board games, I've had a super hard time getting any luck in the industry. I've had a meetings with several publishers, but only got one game signed in about 5 years of trying.

But It's a lot easier if you're a known personality. Like I'm friends with a few people that have made more progress in less time because they volunteer a lot of time in the industry and are pretty well known...one woman has a podcast, works for a game manufacturer, has helped run a few board game conventions, and has three games in the pipeline after in less than half the time I've been trying, but she is fully immersed in the world so it's easier, whereas I'm juggling it with other interests and a job that has nothing to do with the industry. I could be putting myself out there more, but I just don't have the energy for it.

Whereas back when I used to only make video games, I was usually knocking out one or two web games a year, just on my own, and some were getting played millions of times, no publisher needed. If you played Flash games back in the day, there's a chance you played something I made. I still run into random people that have played my Flash games. Two coworkers at my current job alone played them over a decade ago. It has gotten harder to get back into that now that I'm older, slower, and have a wife and two dogs that need my attention, though.

I've considered using Twine for some story-based games before. How are you using it for playtesting?

Congrats. While it can be exciting to come up with a profitable algorithm, publicizing a mean reversion algorithm is counterproductive if you intended to make any money with it. The returns here are low enough that it could stay under the radar for a while, but all the same.

Some other metrics to measure your performance are drawdown, best month/worst month (to see if a small number of events account for the majority of returns), and Sharpe ratio. As other commenters said, try backtesting with fees/slippage. Even if there aren't fees now, you should include fees at points in history when there were higher fees. HFT's have been forced to tighten their spreads as retail traders have become more liquid with lower/nonexistent fees, so that will affect any mean reversion strategy being tested across fee change periods.

I do like the idea of spot mean reverting on large indices. Takes a lot of risk out of it (while a company can tank overnight, any decently weighted index will lack that volatility).
I'd argue that all I really want them to compete on is customer service. All in all this sounds pretty perfect to me. We get quality care, but some element of competition. I've lived under three different types of systems - this seems by far the best.

For what it's worth the original tech singularity idea was from John von Neumann in the 1950s:

“The ever accelerating progress of technology and changes in the mode of human life give the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue.”

Which I guess is kind of in the eye of the beholder.

That said he misrepresents Kurzweil a bit with "if you're Kurzweil all the curves are exponential and they're going up. And right now is a special time." Kurzweil has already said the singularity will be about 2045 and now is not a special time in that way.
Short selling, though, incurs an additional borrowing cost. That's been going up for ETFs since 2020. "The price of short-selling U.S. exchange-traded funds has jumped dramatically since the beginning of March as investors seek to stem heavy losses in the wake of the coronavirus epidemic, according to data from S3 Partners."[1]

This needs to be re-run with the borrowing costs added.

The fact that EFT short selling costs have gone up indicates that others are active in this space, which means the profit opportunities for a simple algorithm have probably been already taken.

"All that the corporation tax adds to this picture is the creation of work in tax avoidance services, and an unjust inequality between those firms that can afford those services and are structured to take advantage of the rules, and those that can not and are not."

This already exists in the United States.

An "S-Corp" is a passthrough corporate entity wherein the corporation (or partnership) is not taxed at all and all profits flow to the owners of the entity who are then bound to pay the taxes on their personal returns.

Almost all small businesses incorporated in the US are such entities. It is not exotic in any way and is totally accepted and normal.

The trick is ...

With some minor exceptions, all of the profits need to flush out of these passthrough entities every year. You can't just keep piling up untaxed profits in the company bank account. The corporation is required to disburse the profits and create taxable income for the owners.

Big coporations which are not passthrough entities can keep the money and do not have to disburse it ... but they have to pay taxes on it.

So there are pros and cons to these structures.

I personally feel that passthrough corporate entities are much simpler, much more comprehensible and do not have the societal inefficiencies (pursuing tax avoidance strategies, for instance) that you mention. But at the same time I think we're asking for trouble if we let (big multinationals) just pile up bigger and bigger mountains of cash in their bank accounts, untaxed.

So, in absence of a better solution, taxing non-passthrough entities seems like the least worse solution ...
First, Nuclear is more than 10c/kWh unsubsidized at 90% capacity factor, which only gets worse as you try and scale up. France got into the 70% range and they had countries to export to. Nuclear is not even vaguely competitive even without energy storage involved. Just the fuel rod lifecycle alone costs almost as much per kWh as solar. 24/7/365 security is only the tip of the iceberg when you look into why Nuclear is so stupidly expensive. Maintenance for example takes up roughly 1 month per year of operation and you can’t send the guards home.

Anyway, it’s the same in that their all indirectly producing CO2. In a full accounting all of those things that make nuclear expensive actually produce CO2 because construction equipment, mining to produce the parts to build a reactor, etc etc all produce CO2 in the current economy.

In fact if you do the full breakdown for all activities related to Nuclear Reactor Construction, Operation, and Decommissioning their a very significant CO2 source in large part because all economic activity is and their really expensive. Regardless of how easy to draw arbitrary lines that ignore say CO2 emissions from workers daily commutes etc.

The only way to move past that is to have serious energy storage that’s used for all equipment and thus very widespread adoption of cheap battery technology. At which point Nuclear costs become an even larger issue because cheap batteries tank the cost of battery backed up wind/solar. In the end far northern countries can make some use of Nuclear, but it’s a dead end technology without a significant role in actually solving climate change.

The thing to remember is people are nearly always motivated by selfish impulses, not altruism. (Even the most dedicated communists in the USSR still participated in the black market.)

Any system that relies on people being selfless is doomed to failure.

(Even charity work is selfishly motivated - people like the status they get from donating to charity, praise from their social circle, and feeling good from doing it.)
