Not necessarily.

According to philosopher Paavo Pylkkänen, Bohm's suggestion of the quantum mind "leads naturally to the assumption that the physical correlate of the logical thinking process is at the classically describable level of the brain, while the basic thinking process is at the quantum-theoretically describable level". [1]

Factoring integers is a logic operation (thus not performed at the quantum level). But an operation like identifying an object or a smell (as it is what the article here is about) could be performed at a more deep level using quantum mechanics.

There are theories [1] that part of the brain's function might work at the quantum level. If true, we probably won't be able to really understand what happens by measuring it this way...

> I just don't understand why so many trillions of dollars around the world are being spent on military power that just sits by and watches dictatorships kidnap protestors from other countries and execute them.

We make wars to control energy sources, trade routes, etc. The west as happily puts a dictator in place of a democratic government when it's in their interest (or the best interest of the men in power and their supports).

> So why are there ads on websites? There is only one purpose they serve: to make money.

If there are things that could make Lichess way better but require resource they don't have, they should weight the pros and cons.

The cost is a worst user experience. The benefit is money.

For a non-profit, money is a mean and not an end. Resource will be used to achieve a purpose. Maybe in some cases the benefit can outweigth the cost.

A friend of mine, from Romania, has fond memories of his youth under the communist rule of Nicolae Ceaușescu, being always reminded how great the leader was and how he admired him as a kid.

He discovered later he was only manipulated into that, but still classified this as good memories.

It's a little bit like those old adverts, it doesn't mean it is a good thing to perpetuate.

On a mac I can't live without "Magnet" [1]. It lets you do organize your windows in half/thirds of screens with simple keystrokes. That should be part of the OS.

After years of struggling with config file in heterogenous production environments, I'll argue the opposite: environment variables are the BEST option to manage your configuration.

Nocebo effect is proven for vaccines. Even if we inject salted water: many will develop fevers, arm pain, headaches, nausea, ... (because they expect such symptoms). In some cases, as many as 90% of observed side effects are nocebo. i.e. if 100 people get the real vaccine and 100 people get salted water, 10 will get side effects on the first group, 9 will get the same side effects on the control group.

Great achievement. One remark though, it sounds like the author does a lot of assumptions that something is better without actually benchmarking before and after. On those kind of projects, one should measure the impact of each step. Maybe the new version is only faster because it uses WebGL, maybe the WASM code is actually slower... Or is it the opposite?

In my youth, I did a lot of x86 assembly programming. It's very easy to end up with a code slower that compiled high level languages. Here's an example: aligning memory buffers made a piece of code 50% faster (the bottleneck was memory bandwidth). That's a sort of optimization a compiler might (or might not) do for you. With ASM languages you have the control, so you're responsible for doing it.

Michael Abrash's Black Book is a bible in term of approach to software optimization. It's old but a nice read. Out of print, a free ebook is maintained here: https://github.com/jagregory/abrash-black-book

I never run it manually.

I plug this tool in my scripts that import transactions from banks (and stripe).

The scripts extract transaction details (amount, payee, currency), then they use `ledger-guesser` to create ledger entries and add them to the journal.

The generated entries are "uncleared". Then I manually "clear" the entries. Review. Commit. (You can also use a tag for reviewed transactions if you already use ledger's "cleared" indicator for something else).

For the best results, I have 1 journal per bank account. So I have different training data for each bank account.

There's no confidence threshold. When there is a new type of transaction is encountered, the guesser will chose the account with the highest probability.

The guesses are made based on the words found in the payee (and date). Unknown transaction have generally a few known tokens. Example: "INCOMING TRANSFER FROM NEW_CLIENT"... The classifier will probably classify that entry as "Incomes:OurLargestClient". In that case I have just to fix that entry to change the client, all the rest is good, it still saves a good amount of typing.

I use ledger-cli + ledger-guesser [1], which uses use machine learning (brain.js) to classify entries automatically.

I've been relying on this for the last 3 years, it works very well.

Funny how "lottery" is the word that comes out the most when we talk about making games for a living.

Big studios solve this by publishing games by the hundreds.

Game publishing is a numbers game. Most games go unnoticed, very few will break even, only "lottery winners" will make real money. The stores are full of well executed games with original ideas that you/we never heard about and never will. Games in page 1 of each category will make money, then there is those from page 2 to 10000.

We've spend a year and a half building a game that made us just over $1000. You increase your odds by having a name in the industry: known game designer, known franchise, known publisher, something that will put you in the front page of gaming websites for a few hours, but even that is just a push, no guarantees. You can also go for a quantitative strategy: build lot of small simple games. This last strategy worked better for us.

Make sure you take this decision knowing that failing is by far the most likely outcome. That's the hard truth about the game industry.

Sorry if those are not the encouraging words you hoped.
