Electric vehicles are 6 times more efficient than internal combustion, so even using coal fired electricity to charge them is a win https://evquotient.substack.com/p/how-evs-are-by-far-the-mos...

It also allows for a transition to more renewables in the grid over time.
What other device? If I'm out and about and my phone gets stolen, broken, or even the battery just runs out, how do I pay for my transit ride home, where I -- maybe -- have a backup device?

This is the -- pretty common -- failure case I worry about. And yes, I know it's also possible for physical wallets to be stolen. But cash doesn't "break" or run low on charge. Software bugs or internet access issues don't cause paying with cash to fail.

Example of stupidity: I can pay for transit in my city with my phone. However, there are newer payment readers on a small percentage of trains here that just don't like my phone, and insist "Invalid Card". The company that manages support for the readers has been unable to help me. The older readers on older trains work fine. The older readers on all the buses work fine. But I have to carry a physical transit card with me all the time anyway, and -- amusingly enough -- it's more convenient to tap the card than to unlock my phone and hope it works.
Turns out the white wigs they wear are actually clown wigs.

Yes, the question is how much of a boon it needs to be.

The fact of the matter is that people with capital want to invest and grow that capital. It is absolutely false that if that activity is taxed, it will disappear. Just as obviously, if all capital gains are taxed at 100%, it will disappear. The question is the balance - how much to tax it so that the wealthy don't merely get wealthier at everyone elses' expense.

It may also be a good idea to tax underutilized capital, as land is taxed.
> I've found that unless I write code in golang in a way that was intentionally written to be unit tested, it is very hard to bolt on unit testing after the fact.

Absolutely. This is true in most, if not all, languages. But when you're in the driver's seat, able to make choices like whether or not to use fx, why would you bolt on testing after the fact?

Not much you can do about legacy code, if that's what you have to deal with, but when dealing with legacy code it is unlikely the authors used fx, so...
I don't know if its state specific but there were some lawsuits in the past that removed this restriction and a cash discount is okay or a surcharge for credit card should be disclosed before you pay.
Do they use it because it's "just fine", or because there's no alternative? How many people have daily problems with it (problems they might not have if cash were an option), but we just don't hear about it.
Scientists used to believe in phlogiston, so who can really say if oxygen is real? /s
The difference is even more than I expected.

On my hardware, a simple Set->Get scenario takes TBKV 1500 ns/op where sync.Map takes only ~80 ns/op to perform the same task.

That's a 20x difference in duration :(

Yeah typically around 1.5% in Australia. Which is often passed on to the consumer at the point of sale.

We do have a non-Visa/MC payment system here in 'eftpos', which is ubiquitous. AFAIK this is exclusively debit not credit, but this isn't my area, I'm just a consumer.

European Union solved big part of the problem many years ago in 2015 with a new law. They capped the fees of Visa and Mastercard at max. 0.3% of the transaction volume on private consumer cards.

It has many upsides (especially increased acceptance). The only downside: There are no real or good cashback programs (like getting 1-2% back) in Europe because of this.
So you read general news only and not their blog.
> even if it does save me time today when I'm typing in the code

IMO this is the strength of Ruby/Rails. You can have something up and running incredibly quickly, but for complex applications it can easily become a mess. It's not easy to know where something is defined, what type it is, if it can be nil, if you're unknowingly calling the database one or one hundred times with your fancy one-liner, etc.

Of course you CAN structure it all nicely beforehand, and even use type systems, but that's hard to get right, and at that point, you might as well use something else.
I don't. Neither does my voting jurisdiction. The electronic counts are only used for early estimates and everything is officially counted by hand.
CoD. How did that even work? I mean how was fraud prevented? Did money get counted and balanced every night? How did they prevent drivers from getting robbed or inadvertently losing money (miscounting etc?$
A big new concept in Go is that methods can have value receivers or pointer receivers. In C++ and Java, there is no distinction. Plus, method calls automatically deref pointers.

I think it took me a day to realize this when my code wasn't compiling.

That, and goroutines + channels (especially blocking behavior).
Agreed, compilers do now. In 1978, they did not. (although maybe even then things like BLISS, on minis, did?)

The machine I learned C with maxed out at 64K data. Needless to say, the compiler was not doing much beyond peephole optimization.

Looks like this requires Docker to be available?

Personally I've been making OCI images using Nix, just by running tar, sha256sum and jq:

- We can get a Nix derivation's dependencies using `writeDependenciesToFile`

- We can put these dependencies (alongside anything else we like) into an OCI "layer" using GNU tar: the `--hard-dereference` and `--mode=755` options work well, and we can include directories using `-C /foo --filesFrom=foo.txt` where foo.txt comes from `cd /foo && find . -maxdepth 1`, with the leading `./` removed.

- A "digest" is just a JSON file like `{size: 123, digest: "abc"}`, e.g. generated using `stat` and `sha256sum`

- Those sha256sums can be referenced in a config.json, like `{"rootfs": {"type": "layers", "diff_ids": [...]}}`; along with the application-specific config (EntryPoint, WorkingDir, etc.)

- Finally, a "manifest" is just another JSON file; with `{"mediaType": "application/vnd.oci.image.config.v1+json"}` for the config digest, and `{"mediaType": "application/vnd.oci.image.layer.v1.tar+gzip"}` for each layer digest.

Unlike Docker, these commands can all be run directly (from the "host", although it's not really hosting anything, since we don't need any containers or VMs to run the above); their contents are completely declarative (since we're just zipping up pre-existing files, e.g. built/fetched by Nix; rather than mutating a filesystem in-place); we can do it on any OS (e.g. no need for a Linux VM on macOS); etc.
Processed meats usually have preservatives like nitrates or nitrites in them. It doesn't matter what bacteria is detectable when the meat leaves the factory. The bacteria are not going to propagate in the meat.
To note, all of these work on PayPal, with a bank account.

PayPal are a dick on fraudulent merchant account detection and it’s well know assets can be frozen on a whim, but at this point it’s the one of the few other options.
Apple is just building a front for credit cards, so that they can take over the payment space once the customer has shifted their way of doing things.
I read, at one of those companies hundreds of people are working on crypto/blockchain.
>I'm no fan of crypto, but the one place where I can see real utility for blockchain is as a backend settlement service for banks.

So... what does the crypto provide there that a simple authenticated communication protocol with a few redundant centralized servers doesn't?
Crap. When did that happen? I swear I bought like two or three not that long ago and they were like 40 or 50 apiece.
Nobody really has rewards.

We don't have them in Europe, and some people in the USA think they have them.

What they have is crazy high credit card fees and the need to juggle a bunch around to get a few things credit card companies decided to buy for you en masse.

When I buy a $5 latte, I give Visa $0.01. When you do the same, you pay $0.15.

Come the hell on. "REWARDS". Smh.
It's exactly the opposite.

Mercado Pago, from the article, represents a merchant processor, and certain consumer services. However I think the big change in Brazil is Pix, offered by the central bank. It allows instantaneous bank transfers for most cash accounts. The fees are 0 or nearly 0.

As far as I understand, Mercado Pago's big thing is installment plans. You can buy almost anything in Brazil "em ate 12x sem juros" or up to 12 installments without fees.

> Much of the original hardware bring-up was done by Ubuntu Touch. Mobian developers built the telephony stack via their eg25-manager project. And in my role for the postmarketOS distribution, I developed the camera stack.

> Manjaro Linux has been largely absent from these efforts.

> In some cases the Manjaro involvement actually causes extra workload for the developers by shipping known broken versions of software and pointing to the developers for support. Which is why https://dont-ship.it/ was started.

Other distributions like Mobian and Ubuntu Touch are miles ahead that broken thing that Pine chose to adopt as their default distro.

When I got my PinePhone, nothing was working, not even the home screen! So I looked for help on the forums and people were like "LOL no one uses that, just install Mobian or Ubuntu Touch". I tried both, and they were actually pretty OK, I could more or less daily drive the PinePhone!

I think the main reason people repeat that the PinePhone is not ready for use as a daily driver, is that the default distro is completely broken. Pine64 are shooting themselves in the foot in a spectacular way.
"ally" in this case means something like "marriage of convenience"...
As far as I can tell, largely they are trusted when they result is the desired one and distrusted when the result is not the desired one, since people mostly care about making sure that they get the result they want, not with making sure that the process is "fair".
However, the legal systems can still be wildly different. The ounce of marijuana that anyone over 21 can buy from a state-licensed shop and possess in Colorado could mean a $2000 fine and up to 6 months in jail in Texas.
The majority of the world is not "tech people".

And even with backups, you still need to buy a new (minimum $100?) device if yours gets lost, stolen, or broken. Should it really cost $100 to replace a payment card? For many of us here, $100 isn't a big deal, but for a lot of people, that amount determines whether or not they eat this week, or manage to pay rent this month.
We produce lots of chips now, and soon we're going to be producing enough for ourselves.

Dr Pepper is often bottled and distributed by Pepsi or Coke, especially outside of the US. Coke has a competing "pepper" drink (Mr Pibb), but mostly markets it in areas where the Coke distributor doesn't have rights to Dr Pepper.
I presume instant payments don't have the chargeback feature of credit card? That is the main benefit I care about credit cards.
Just wait until staking is merged, 67% of the pools are run by centralized companies wanting to do business in the US, and they start filtering at the transaction level, including or not in blocks based on these same dirty metrics.

>The unavoidable Tesla comparison sorry, I am not convinced. What functionality is better?

I never said the functionality was better. My post says "The functionality here isn’t materially different from what Tesla offered." 5 year old Teslas, today, do not have laggy interfaces.

Your claim that it will be "easily" fixed will remain to be seen. Ford isn't new to touch screen interfaces. Every consumer has been opining for Android Auto/Carplay because they know stock interfaces will be laggy, unresponsive and unintuitive. This has been an issue for years, before EVs, and it takes a very healthy amount of optimism to believe it will just be fixed next year.

The iPhone was able to have smooth, responsive interfaces on a battery powered device in 2008. That was 14 years ago. How much more powerful of a device do you need than the iPhone 3GS to open a touch screen menu at 30fps? Only a handful of auto manufacturers care about software, and it's been that way for years. This isn't new.

That link doesn't show that housing was not an investment for centuries, does it?

As your post illustrates credit cards are really a solution developped for the deficiencies in the US banking system which have been exported to the rest of the world due to the dominance of the US market. 20 years when I was still living in Germany, hardly anyone had a credit card, while everyone was using automatic payments and electronic wiretransfers. I was very surprised when later (about 13 years ago) a US friend told me that they were still using cheques for most things. I had only touched a cheque maybe 2 or 3 times in my life.

Even today many people in Germany still don't have a credit card or if they have one largely use it for travel. Of the people (in Germany) I know, they also never use charge backs on the cards (I suspect many don't even know that you can do it) and instead rely on the court system to get refunds etc..
I think we have different definitions of the term "concrete solution".

I get a minimum 2.6% cash back on everything I purchase, but most things I get 3.5% to 5.25% cash back.

There are a bunch of free 2% cash back credit cards, so people would at least break even if they wanted to.
I don't understand how this is possible:

"Merchants hand over some $138bn in fees each year; according to the National Retail Federation, a lobby group, it is their second-biggest cost after wages."

Unless they're talking about more than just credit card fees? From the same article:

"But credit-card fees are unregulated and meatier, usually sitting at about 2% of the transaction and rising to 3.5% for some premium-reward cards."

Are they saying that retailers pay less than 4% of the retail price to acquire their goods? They pay more for credit cards than rent?

> If I move a shovel full of dirt to the same place in my backyard every day for 20 years, I'm going to have a big pile of dirt there.

Not that I disagree with your general point, But this is why prediction is tricky, because unexpected flooding and your prediction is false.
Looking at the tweets in question linked from that article [1], many of those are statements of blowing up airports or making death/rape threats. I, for one, appreciate the idea that making death threats online have consequences. Often these are the only signs you get before mentally ill people act on them, and in most cases police can do nothing until an actual crime is committed...usually that crime is murder.

There's a difference between getting arrested for tweeting for social change and for, well, calling for deaths. There's certainly a grey area about "jokes" here, but you haven't been able to joke about "the bomb in your pants" in airport security lines for the entire history of airport security, so it's hardly a new global trend. It's also different when someone with millions of followers "jokes" about something. Before Twitter, this woman would've still been arrested for what she was advocating, and that's what makes her situation awful...not that she got arrested for tweeting.

We should be compassionate when applying the law and continue to figure it out, but let's not throw the baby out with the bathwater.

Shamefully, a few YouTubers I have subscribed to for a while started shilling this bullshit as video sponsorships.

Needless to say, as soon as I looked up the company (it smelled more like bullshit than a cattle farm) - I saw on a rudimentary Google Search that; of course you can’t buy a square foot of land and be a ‘Lord’.

Needless to say, I got rid of those subscriptions right after.

It’s unfortunate how some YouTubers who get sponsored either don’t even Google the companies they shill for, or in the case of someone like AVGN shilling ‘Raid Shadow Legends’ - they know what they’re shilling is complete shit.
What you are describing is not a Ponzi scheme at all. It's just regular unsustainable growth.
Yep. Also one of the reasons crypto will never work (as-is) for online, digital currency/payments. Customers don't want irreversible transactions.

I picked up an HP ENVY Inspire yesterday to do some experiments to see if I can create images of modern tech but produce something that reminds me of the nostalgia of the 80’s CRT’s using the CGA palette (cyan, magenta, black, and white).

As a long, long time user of React (from back in the days before they even had a decent state management system and we were using libraries like "MartyJS" to handle state) I do feel like React has lost its way a little bit for regular users.

What benefits are the hooks providing over class based components to the average user?. I understand Facebook probably has very unique requirements around performance but 99% of people using the framework probably don't suffer from these problems but have to put up with the downsides of the occasional weirdness that hooks introduce.

Example, the way you have to handle useCallback is something that bit me very recently. I had a parent component tracking deleted gallery items as a map of ids and a boolean indicating if the image had been deleted. For some reason I couldn't figure out why the deletion map was always stale in the callback. Sure I had a useCallback around it but I'd correctly added the state variable in the dependency array of the useCallback hook.

Well, it turns out I need to pass the deletion map down to the child <Image /> components of the gallery where the deletion was called from because they also had a useCallback in them. The child image components have to know about all the images that have been deleted so that the parent component has the correct up to date state. Crazy!

I get that it's Facebooks project and they can do what they want with it, but I have 6+ years sunk into using the framework now, it's a lot to throw away. That said, I have high hopes for the combination of LiveView and Web Component based libraries like https://shoelace.style/
