I always wonder where this belief comes from. The stuff we buy from China doesn't take that much energy to create compared to, say, driving 10 miles to the grocery store a few times a week.

Consumption-based CO2 inventories, that allocate emissions based on the country of the final end-user, are remarkably close to production-based inventories.

For the US, highly geographically resolved, consumption-based CO2 estimates show that most of our energy goes to suburban land use patterns: tons of transport fuel for lots of driving, and high heating/cooling costs due to detached, poorly insulated buildings. The typical city dweller has a carbon footprint 1/3 of the surrounding suburbanites, and the difference in consumption isn't about the things they buy from China:

Politicization threw a wrench into COVID and it’s doing the same to climate change. Years of media gaslighting, fear mongering, and authoritarian tactics have left us in a social reality where nobody cares any longer what the talking heads in the media or shouting on social media have to say.
Ive been meaning to try out the MAME version that the MAME devs added a few years ago. Not sure the speed is there but that could have changed, have not followed it too closely. Think they also added SGI Iris so you can say 'hey I know this'.
I think you should spend some time plotting throws of the last 20 years using performances from top athletes the worldathletics website. You'll discover that you are mistaken.

This suggestion is related to to for why the claim matters, which is familiarity with the sport (as represented by the ability to name its participants). As a longtime participant in track and field, athlete, coach, and fan, I have invariably found that people reduce perceived phenomena to doping usually have no idea what's actually going on in the sport and aren't involved in it in any substantive way. So, "show your familiarity" is a jabby heuristic to prove the point.
How are rocket launches "ultra low efficiency"? Compared to what? I mean, no one is putting stuff into orbit with any other technology.

Rocket engines are the most efficient heat engines in existence, and the energy efficiency of a rocket (in the sense of fraction of jet kinetic energy that ends up in the kinetic + change in potential energy of the thing put in orbit) can be very high.

It takes a lot of propellant to get to orbit. That isn't because rockets are ultra low efficiency, it's because it takes a lot of energy to get to orbit.
I believe that what happened in the latest 20 years actually shows that multiplexing, for very short-lived requests, won: multithreading is, very often, only used at this point only to scale the single multiplexed approach to multiple cores. Now on disk databases still use one thread per query models, but hardly anything that serves small objects uses the operating system paging as a cache, including on-disk stores that have their own paging mechanism and never trust the OS to do so.

The 256 byte thing was an old story, pre-memcached, that I recounted at some point, that has nothing to do with Redis. I implemented an on-disk cache for slow SQL queries: since the filesystem had issues with inodes, I created a 256 directories, each nested with 256 (so 256*256) in order to lower the number of files for every directory. This used to play a lot better with filesystems of 20 years ago.

Btw here the main point is: nobody is using, at this point, the OS paging as a caching layer in databases, and that was my point back then, and I don't see how it is not true. And, to serve small objects, multiplexing won and threading serves as a way to scale multiplexing itself (see memcached, for instance).

IMHO it is more interesting to provide arguments than to attack single persons you may not like :)
I did not say that. I wrote "Wind pushes the propeller."

The vehicle is basically extracting energy from the difference in velocity between the ground and the air.

The wind pushes the propeller forward, the ground pushes the wheels backwards.

You can set IFS='' globally, which disables splitting. (And you have to make sure it stays that way, since there are some idioms which modify IFS)

Although there is the "empty elision" case related to splitting: if x='', then $x is different than "$x", even if IFS=''.

You could also use zsh which doesn't do word splitting, but does "empty elision". (I'd say zsh is a better interactive shell than a scripting language, but I've seen it used on occasion.)

Or you can use OSH, which will run your bash script as is. And then you can opt into shopt -s simple_word_eval or the group shopt -s oil:basic, and EVERYTHING will be "unmolested", quotes or not:

To offset our entire current greenhouse gas emissions with trees alone, we would have to increase earth's total plant biomass by 10% each year.

Given how slow most types of trees grow that seems completely unfeasible unless we give up most meat (taking space that we now use for growing animal feed).

(Yes, we have a lot of space in the desert, but studies show limited effect on global warming from planting anything there once you account for how well sand reflects heat back into space).
The smarter, if potentially less ethical solution is to encode such images and make memes with them. One of them going viral is likely to flag an enormous number of people along the way.
Presumably because the employer wants to intimidate the workers to extract more. Once an employee is surveilled, an unscrupulous boss gains all sorts of leverage that can be applied in all sorts of ways.

A bit off topic but notice you have a golang version of your JSON parser lib as well.

Not saying that is not true. Yet living in one of the few direct democracies it is the very best we have in terms of democracy. On a bigger scale liquid democracy may is more interesting.

This is not substantive. Please read the HN guidelines.
Different sort of runtime, but fair point.
It's not at all counterintuitive. It's just poorly explained.

Energy is 1/2mv^2, and momentum (related to force) is mv. Anytime you have different speeds, you can arbitrage.

If I am pushing against still air, I can generate nearly-infinite force for arbitrarily little energy.

That's why you use wings instead of pointing jet engines downwards. You push a lot of air by a little bit (lots of mv, not a lot of 1/2mv^2, since v is small).

If I am going an epsilon faster than the wind, with very little energy, I can push hard on the air.

If you think all cryptocurrencies are scams or think blockchains do nothing useful, please skip this comment.

If you think things like decentralized finance, storage and identity have the potential to improve our lives and offer some of the only genuine alternatives to an increasingly privacy-hostile status quo, please look into the shambolic legislative process that threatens the entire blockchain industry in the United States. This is the time to act and ensure that cryptocurrency provisions are debated meaningfully in Congress before any relevant legislation is passed. What the Senate is doing right now reeks of both outright incompetence and malice. There are many, many companies and builders active on HN who are about to have their existence challenged.
My claim about the Lua C API was that, being a stack-based API, it is hard to use. It's a tradeoff between simplicity and usability from C. Please show me the code I wrote that shows how my ideas about lack of usability of the Lua C interface is due to me not reading the documentation.

Note: interpreters are not entirely out of my specialization, I wrote a Tcl interpreter that is still in use in embedded systems, participated in the Tcl community for a long time, reimplemented the Joy concatenative language extending it, and so forth.
The angle of attack of the propeller blades and the gearing relative to the wheels cause the blades to be seen by the wind as moving upwind relative to the ground.

Alternatively, think of it as merely harvesting energy from the velocity difference between the ground and the air. It's connected to the ground by wheels, and to the air by a big prop.

It doesn't matter how fast the vehicle itself is moving as long as the gearing is right.

Ultimately, the top speed is limited to when the friction the vehicle encounters from drivetrain losses and aero drag exceeds the power it can extract from the wind/ground speed difference.
Yes, I think the point still stands. A carbon tax is an efficient measure that will reduce emissions and not harm poor demographics.

However there are other things we can do as well to reduce emissions as well as increase life quality at the same time (improve public transport and bicycle infrastructure) where poor people benefit especially.
> No, the problem will never be dealt with for as long as we focus on attempts to brow-beat everyone into self-sacrifice - to which people naturally react by ignoring the beating and resenting the beaters.

"Not mainstream" is key here. Once those become mainstream, they get shut down by the provider of the original service.

The original provider wants to make money off this, so they use the UI to provide you with ads and a bunch of tricks to keep engagement up. No way they let you off the hook to use what's costly without being exposed to what drives the income stream.

Open APIs, that's what you need. Obviously Facebook, Twitter, Instagram, Google Chat, etc don't have any, for the above reasons.

I'm honestly surprised that email is still a thing. It's the last somewhat open API around. (Unless you count HTTP..)
Probably doing MITM SSL inspection. Basically, a corporate security appliance with trusted certs on the endpoint sits in the middle of everything to inspect for malware/viruses/blocked content.

As I understand it (and I've not spent too long on this, just picking at various articles) - there are two separate things at play here.

Firstly - CASM scanning is done via fingerprinting - the image is fingerprinted on device and when uploaded to iCloud that fingerprint is compared with the "dodgy images" fingerprints and an alert raised if a threshold of matches is reached (what's the threshold and with whom?)

Secondly - there is on-device AI image recognition - when you send an image to someone else (via iMessage or the share sheet) it is checked for nudity and if the iCloud account in question is registered to a 13-year old or younger, their parents are alerted.

In both cases the fingerprinting/scanning is on-device and is triggered by the images leaving the device.

Why doesn't anyone ever question their intent to protect children? There is no such intent. When they do protect children, these are the sorts of observations of what happens when the state has 100% control over children:

https://www.kansascity.com/news/special-reports/article23820...

Why does the state, when they treat children like this, get to proceed on "more" child protection to protect children? Are we totally mad? Any effort to protect children is always a de facto effort to deliver more children into this system, and the state system is much worse than being abused in society (never mind that someone found there's actually more abuse in foster care than with abusive parents! Therefore even if you assume social services is always right ... they never protect kids against social services itself. Therefore you can reasonably assume that a kid that is getting abused will be forced into a worse situation by state "help")?

I mean if you want to protect children, obviously the first step is to fix the child protection system that everybody knows is badly broken (you constantly hear stories about schools sabotaging research into abusive parents to protect the child against social services, covering for the child, lying about attendance or even wounds, ..., because they know social services will be much worse for the child).

There's states where the corrections department provides better care (and definitely better educational instruction) for children than social services do. And yes: that is most definitely NOT because the corrections department provides quality instruction. It's just MUCH worse with social services.

They cover themselves by showing the worst possible situations in society "demonstrating the need to intervene". And you won't hear them talk about how they treat children ... because frankly everyone knows.

Reality is that research keeps finding the same thing: a child that gets abused at home ... is being treated better (gets a better future, better schools, better treatment, yes really, more to read, ...) than children "protected" from abuse by the state:

https://www.aeaweb.org/articles?id=10.1257/aer.97.5.1583

(and that's ignoring that reasons for placement are almost never that the child is unsafe. The number 1 reason is non-cooperation with mental health and/or social care by either one of the parents or the child themselves. There is not even an allegation that the child is unsafe and needs protection. Proof is never provided, because for child protection there is no required standard of proof in law)

And we're to believe that people who refuse to fix child services ... want extra power "to protect children"? How is this reasonable at all? They have proven they have no interest whatsoever in protecting children, as the cost cutting proves time and time again.

Yes but it probably took additional code to only scan pictures that are synced to iCloud.

Various European countries are mandating vaccination or face the following consequences:

- unable to shop/buy food

- unable to use public transport

- no concerts/movies

- no restaurants

- unable to go to hospital

Along with bankrupting fines and jail time for businesses that do not comply.

France, Italy, Germany, Greece, the UK and others are experiencing widespread protest - some in the millions - and unilaterally across some of those countries, in many cities and small towns, as a result. Protestors are unified as vaccinated and unvaccinated - scenes have emerged of vaccinated burning their vaccine passports en masse in solidarity for example.

Most of this is barely reported in world or US news, along with radio silence on the extreme police brutality that often meets such protests.

Search on odysee or other uncensored video platforms, and you'll find countless examples of massive protest and egregious police-instigated violence even just from over the past few weeks.

Figure out the language-specific hashtags for them, and you can find many threads with live video etc on social media in the weekends.

Several organisations and unions are also striking/walking-out against such measures, and this is also not being widely reported, though they can be found in regional, language-specific news.

Most people outside of Europe have no idea what is happening within it right now regarding these issues, because of widespread big-tech and government-supported censorship. This of course also fuels more protest as protestors can see they are not being reported on despite their huge numbers - which then causes more to join as they agree with the injustice.

These protests have apparently only increased in numbers since beginning many months ago, and continue to do so despite increased police violence against them.

One of the central claims of protestors is "medical apartheid", forced segregation etc. Typically, those enforcing such measures are denounced as "Nazi's", and this opinion appears to be widespread and volatile.

It's unsurprising given the history of many of those countries that they would react strongly to what they perceive as a recreation of prior national shame.

>Your individual effect is a rounding error.

Correct, but now imagine you have a large number of individuals not only 1 .

Have you seen just this last week the Blizard/Activision responding to just individual action??? If just a random dude would have protested they would have done nothing, but when "influencers" and communities got involved shit happened, those bastards lost money and they had to do something.
That's fine. My privacy has a price and I'm happy to sell it when I think it's convenient for me.

What's happening here is that a state actor is forcing providers to let the state spy on me.

That's an authoritarian policy which I strongly oppose.
Just like WhatsApp 'conveniently' integrated Google Drive backups by default. That is why it's funny to see the fake outrage of WhatsApp's team over this.
For Facebook to be selling my data, it isn't necessary that they email a data broker some spreadsheet of my personal data. Selling advertisers access to an incredibly intimate and private picture of my personal life so that they can best exploit my specific life circumstances to unduly influence me is exactly what bothers me about Facebook "selling my data."

To claim that Facebook isn't selling my data is a semantic distinction without a difference at best, and just downright dishonest at worst.

If you're talking about the Green Party site, there is explanation at the bottom of the GitHub issue.

Ah, "Reputation" and "Threat Intelligence". One of the things I didn't expect but should have after BeyondCorp and Zero Trust is that some people would decide they need to go the exact opposite direction.

Instead of designing our systems as though they all face the hostile public Internet like Google, why not instead police all of the public Internet as though it's our internal network? That way we don't need to adopt any actual security practices. What could go wrong?
