My 2016 BMW 118d has a navigation system and a built-in SIM card. It is used in multiple instances (the listed ones): locating/locking/unlocking your car remotely (all optional), start an emergency call, updating the firmware and talking to a messaging server
Portuguese license plates for a long time had the month/year of the car manufacture. This been discontinued because apparently no other country in EU does this and it was confused with expiry date.
There is no other indication on the license plate. just the numbers and letters.
I assume that expiry dates on US plates is related to either road tax or vehicle inspection
What people don't realize about cryptos and the current state (of crypto markets) is that the current downtrend is part of a larger cycle where for a period of time new players come into the ecosystem, launch lots of new projects, and then most of the get wiped out when people realize that the model behind the project isn't viable or just crashes.
First we had the shitcoins wave when everybody and their doge forked bitcoin. Few of them survived
Then came the ICO era.
Now it's NFTs and "not banks" like Celsius and other companies that move token custody from on-chain to a "trust me bro" agreement.
"Do i loose control of my tokens at any point ?" - on this Defi era, this is the most important question to ask before depositing your tokens in a contract
Not to mention the Orwellian proposition: "delete the pic we deemed wrong so we can unban you". Apparently it's hard to just delete the offending pic, it's better to teach you a lesson and make you do it.
I owned a mzr700 at the time cd/mp3 players started to come to the market. It looked like something from the future when compared with the cd/mp3 players at the time. audio quality was amazing and minidisks always worked, no skipping or disk damages, and longer battery life than the cd/mp3 readers
Google respects robots.txt. Allowing Google scraping is optional. In fact many websites serve more content to google bot than to you before you log in, google bots clip through paywalls
if the code for the web app is available (assuming a license that permits it) there is no need to use an extension to copy a component. you got the source code
if the code is not available, very likely you will not have permission to use it.
Don't see a legal usage of this kind of tool in a commercial context. Pretty useful as a learning too though
And the cert chain on those is valid. i took a peek when i got mine the certificates (at the time) were issued by a sub-ca which by the name seems to be a gov entity and issue id card certs only. don't remember which company owned the root cert of the signing chain (it was a one of the common root cert used by browsers)
The choice of rsa2048 is probably because of the card specs. it couldn't handle 4096 keys (this was maybe 10+ years ago) from what i've read at the time
A very similar system has been in place in Portugal for some time.
The Portuguese EU id card (probably like all other EU id cards) can be used access multiple government web services. There is also a mobile app to go along with it.
The card contains 2 tls certificates (rsa 2048 bits) and are pin protected (signing operations).
One is used for authentication (there is a public api available IIRC), the other is used for signing (that digital is considered a legally binding signature)
Not sure about the mobile app but i assume the same functionality without the inconvenience of owning a card reader
Vending machines that sell things for 18+ like smoking papers and lighter are required to have a card reader to verify the buyer age
the wallet in question is probably metamask, a browser extension. it injects a web3 provider in `window.ethereum`.
connecting the wallet is done by calling `window.ethereum.enable()`, this pops up a dialog asking you to connect an address to the website. it just tels the extension that the website is allowed to interact with the extension
This article is about phishing in the context of cryptos.
Silent signing doesn't happen (unless there is some kind of bug in metamask). the user is always presented with the contract address and call data (the args to the contract call)

Nobody is stopping you from building apps

Nothing. Plenty of companies use proprietary formats. You can choose to use the company's product or not. On the web3 ecosystem there is code available, at least for bigger and legit projects
Also what are the "core promises". Can you be more specific on that?
This can be either true or false depending on what is your understanding of how blockchains work and what benefits it brings.
Some people will understand it as "some data will be on-chain and all or most businesses will do it", other might understand it as "every bit of info will be on a public blockchain"
Blockchains are very inefficient "databases" in the general sense of a database (and also expensive). They are only used because of the security characteristics. Only data that needs to benefit from those characteristics should go there.
that is the wrong comparison IMHO. if you are talking about money laundering using NFT's as in pics of cartoon monkeys (an NFT is just a digital deed, the monkey pic is actually an extension), you should be comparing them to money laundering using art.
half agree with that. PoW is the most efficient method of converting raw energy into a digitally secure token. It would be much better if the work done was actually useful beyond that.
Some attempts have been done in the past, but with low success (Riecoin IIRC uses cpus to find sequences of primes, GridCoin used BOINC for the PoW, proof-of-boinc in that case).
There is still work to be done on EVM chains. Contract calls need to be processed and verified by every (full) node
1 kwh ranges from 0,15 to 0.16 €
25kwh * 0.16€ = 4€ (100 miles/160km)
My diesel ICE does ~5.5 l/100km (42.8 mpg) and diesel is at around 1.98€/l
8.8 l * 1.98€ = 17.43€
