Python continues to be the ideal language for scripts.
JWTs are good for API tokens, not end users. If you use JWTs for your cookies/session state, then you'll still need to maintain a table of valid JWTs and expire them when the user logs out, and thus you will not be able to use JWTs as they were intended to be used, which is as stateless tokens.

Most security auditors/certifications/compliance requirements do not consider even a 5 minute lag acceptable for user driven logout. The definition of logout is that when the user presses the logout button, all the session data is invalidated server-side during roughly the time it takes for a request/response roundtrip.

Thus there is no benefit to using a non-opaque high entropy string for user sessions, even though there is a good benefit to using JWTs as API tokens for back-end services (esp. microservices) that do not have browser logout requirements.

Bitcoin is essentially dead development wise, virtually all exciting development is happening on ETH.
"figurehead" is a word with a meaning. "Head" and "face" have different meanings.
As far as pump and dumps go, this would make a very tiny amount of money for a company of Tesla's market cap. In another post someone said they made $270MM from selling bitcoin in Q1. On a market cap of close to $590B. And they can only really do that trick a few times at most.

I have no idea what the true motivation for Tesla accepting bitcoin was. But I would be surprised if a publicly traded company took this much risk for such a relatively small amount
Maintainability I suppose.
Don't think they have to disclosing ANYTHING until next quarterly results.
> The Pyramid shows biased behaviors, growing in complexity from the bottom to the top. Although the behaviors at each level negatively impact individuals and groups, as one moves up the pyramid, the behaviors have more life-threatening consequences. Like a pyramid, the upper levels are supported by the lower levels. If people or institutions treat behaviors on the lower levels as being acceptable or “normal,” it results in the behaviors at the next level becoming more accepted. In response to the questions of the world community about where the hate of genocide comes from, the Pyramid of Hate demonstrates that the hate of genocide is built upon the acceptance of behaviors described in the lower levels of the pyramid.

The point being made was that this is really bad because it’s a step on the way to genocide.

That’s what DHH said I believe.

And it would be in the context of trying to get the employee fired who made it.

Also the other co-founder is Jewish. So having someone bring up something like that is probably insulting.

no such thing exists.

Velveeta can't even be called “cheese spread” despite having more similarity to any reasonable definition of that term than any non-dairy simulant has to yogurt. If people want to sell and buy plant-based yogurt-style products, that’s fine, but sellers of sich goods shouldn’t expect to be allowed to call them “yogurt”.

A good open-source example of this type of problem is CodeMirror (a code-editing widget for the web). To achieve syntax highlighting and everything else, it basically fakes every single aspect of text editing in a browser context - even the cursor and text highlighting - replacing the native versions with pixel-placed DOM elements driven by JS. It receives raw events from an invisible textarea and does everything else itself.

This is just about the worst possible use-case for the DOM: you get almost none of the benefits, and still get most of the costs.

>US taxes global individual income...

Always wondered why US citizens do not make a bigger deal out of this. If I understand correctly, if you are a US citizen, but live somewhere else in the world, IRS still expects to be paid tax from your individual income in that foreign country (possibly in addition to the tax you pay in your country of residence) right? I assume there are minimum income thresholds but still...

Are there even any other countries that do this?

I'm not sure what buying a Tesla with cryptocurrency looks like, but I realized if they're not careful, they could get run over during market swings and find they made $2,000 less on a sale. Today is a bad example, but the value is down 12% in 24 hours, some undoubtedly from this news. You can't afford spreads like that with Tesla's margins.

I think something like this is the real reason for this move. Bitcoin is inefficient when it comes to energy use, so it's a bad choice for small transactions, but for a single, large transaction, the environmental costs aren't that bad compared to making a car.
That content can easily be moved in bulk though. It is true that you have to use git-annex command to do so, but this is different from LFS where the complete set of historical files is only stored on the server and can't be moved at all.

edit: The article claims it's a "one-way door" because you can't move to an altogether different system without rewriting history, which is true of git-annex. My bad.

Since Day 1 - Bitcoin was worth 1000+ Bitcoins to 1 USD. Yesterday it took $59,000 USD to buy 1 Bitcoin.

It's had a few sharp downs. It's had a few long plateaus of a year or so.

But - from the perspective of yesterday going back a few months - it certainly seemed to only go up.

If the S&P was up over 59,000,000x in 12 years, people would say the S&P only goes up... I mean, they already say "stonks only go up".
Gell-Mann amnesia effect[1] by Michael Crichton.

“Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them.
In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.”

It would be a huge problem if you're an aspiring mechanic or anything related, but that's an increasingly niche role so we aren't worried about kids not having mechanical literacy. Many kids are aspiring to work in roles where computer literacy is vital and becoming more so every day. The one's that lack the fluency to do things like automate the repetitive parts of their jobs will gradually not be adding enough value to be gainfully employed.

Not being computer literate will have a huge impact on their careers, not being car literate won't (for most).

The issue is not deleting the cookie. The issue is that the JWT can still be used as a valid session unless you have some sort of blocklist. Once you introduce a blocklist, you might as well ditch the JWT and use some opaque token stored in a table.

Wow. Sorry for op. But it is a wow.
As someone who used to scrub more than brush teeth:

According to my dentist brushing too strongly can cause your gums to recede. And apparently they don't recover so damage is permanent. You are meant to use about 80 grams of pressure, which is pretty much none at all.

A decent electric toothbrush like a Sonicare feels like it cleans much better with hardly using any pressure. The base models are fine, all the additional options are unnecessary if you just want to brush your teeth. Personally, switching to an electric toothbrush has been the best thing.

Because a user could simply provide the cookie again on the next request. If you still see the JWT as valid even though you deleted the cookie, the user could stay logged in during that time.

Cookies are managed by the browser, hence they are ultimately controlled by the user.
This is a reasonable criticism. Let me try to counter.

PoW doesn't protect you from a large enough cabal of power (in Eth's case, developers and whale bag holders) controlling the direction of the chain, or censoring entities they don't like from continuing to contribute.

What it does do is ensure that this large cabal can't erase history that happened. The only reason Ethereum was able to fork was because it was still young, they moved very fast, and there was enough external incentive from all parties to ignore the lost mining costs. And even with all that, Ethereum Classic still exists with all the PoW post DAO hack preserved.

On the other hand, PoS has no cost associated with writing the blockchain as far back as you want. If a majority cabal of stakers agree to rewrite history, they just do it. They can rewrite the chain from the dawn of proof of stake with whatever changes they want and it looks equally valid as the "true chain". No energy intensive hashes needed.

With PoS, you have to compromise a large enough number of stakers to mutate the chain. Very little cost after that.

With PoW, you not only have to compromise the miners, but you need to force them to burn tons of real world energy to catch up to the current block to rewrite the chain. Insanely expensive and effectively impossible the farther back in time you go.
Nobody was complaining in 1982 when that very same court system ruled that they had the right to live on the property as tenants. The people who are being evicted did not dispute the court's ruling at the time and agreed, in writing, to the terms of that ruling. Now, after 40 years of not paying the rent they agreed to pay, they are facing eviction -- and suddenly that same court system is too biased to give a fair ruling? Seriously?

It's not illegal to buy a stock and tell people you bought it. There are entire businesses whose model is "make an investment, and then tell other people why you made it hoping they will make the same one". This isn't criminal, it's good business practice.

The thing he got in trouble for with Tesla was for lying about about a takeover offer, which is criminal, basically because it's a type of fraud. This isn't that.

Not a lawyer, not legal advice, etc.

Wait, hold on though. You just jumped from reading to writing.

You are literate if you can read an arbitrarily chosen book. You are an author if you can write a book. Similarly, you are computer-literate if you can accomplish tasks in an arbitrarily chosen program and maintain a system. You are a computer-author if you can write a program.

We use literacy to describe understanding, not creation. What you're claiming is the equivalent of saying that modern generations can't be book-literate unless they're writing fan-fiction.

I would argue tech-literacy means understanding the common language of tech/UX today and being able to use common technology. Someone is tech-literate if they can "read" technology and are comfortable with common interface conventions, terminology, system maintenance, etc... Anyone who sets up a streaming platform using OBS, who manages a community using admin tools on tech platforms, who figures out how to tune games that they're playing to accommodate recording without dropping frames or de-syncing audio, who sets up microphones and figures out how to balance audio using mixers, who edits the result and uploads it to Youtube -- they would fall very squarely into that category of literacy. They clearly know how to "read" software, even complicated programs like video editing tools.

Because the session material could be compromised. How do you revoke tokens on lost laptops? What if you accidentally checked the token into Github and realized your mistake? What if malware captured the token? You have to be able to revoke access on the server side.

You can use JWTs and have a "revoked_sessions" table that works like a normal "sessions" table. At the start of the request, check if the token is in the "revoked_sessions" table and deny access if it is. But there simply isn't a point; this has the same performance and latency considerations that a normal sessions table has ... but with many more possible ways to screw it up. "Sessions with extra steps."
Battery Breakthrough for Electric Cars
Shell companies are just companies without offices. You can use corporate entities to organize assets, create trusts, hold certain obligations, create joint ventures, provide equity to align interests, etc.

All of these things are beneficial.

If you treat this like a game and try to win it, though, the 'building block' of legal personhood can be broken. The mechanics aren't perfect.

You can book profits to one entity, then losses to another by creating 'fake' intercompany transactions, despite the fact that your organization as a whole is net even. We have rules that attempt to deal with these problems in arms-length transactions - regulators get to check if the contract payment amounts make sense.

If you do this with IP, which is hard to value, tax offices have significant issues disputing the value of the inter-company contracts. You use this issue to toss losses between various national corporations to take advantage of problems with individual tax regimes. The double irish/dutch sandwich technique is a great example.

But eventually the chickens need to come home to roost, right? Well, not really. Tax haven jurisdictions basically allow you to park money which you've obtained via your tax avoidance system in an account nearly indefinitely. You'll generally need to pay for a resident or residents to sit on the board of your tax haven jurisdiction corporation board, which lets them scalp 50-250k a year from you, but if you're hoarding billions, it's irrelevant. IF you're a normal joe, however, the accounting, legal and director fees kill you. Oddly, if you look at the leadership structures in place in most tax havens, they look a lot like a bunch of banker expatriates from various financial hubs (hi London!) took over a country that has good weather and nothing else going for it.

The locals receive the windfall of money via directorships and other ancillary financial services, the rich get to hide their money, the companies get to defer tax payments for as long as they want. The only people who don't benefit are the people left holding the tax bag.

Oh wait, that's most of us.
