Totally agree cars are not the right mode of transport for cities. I'm a big fan of park and ride solutions for this - drive to the outskirts, dump the car and ride the train/bus in. I don't think it is really fair however to ask people who live in rural areas to move to cities. In general rural areas are more deprived so I would hazard a guess that many of them couldn't afford to live in the city even if they wanted to. Plus we do need people in rural areas - agriculture and tourism are both important industries.
Apple's A13 – Desktop Performance
What about using a fine screener/mesh on drained water in the wash machine (ie similar specs to that wash bag) to filter out all outgoing water? This would add a mandatory step to clean it up regularly (and ideally not with water in the sink so all of it just ends up in waterways anyway).

Or some replaceable filter in style of vacuum cleaners, that could last a year or two and wash machine would indicate the replacement time. This doesn't seem unsolvable with proper regulation.
Isn't it the idea behind some other kinds of blockchain ? computing things other than hashes so that you get currency and results ?
Yup. London was actually fine, although still too many vehicles parked outside the City. One can set delivery times in the morning at 5 or 6 to 7 or 8. Pedestrian areas also need access for the fire departement, since they cannot carry the water/foam in buckets.
Can "using the wrong equations" explain gravitational lensing effects appearing apparently out of the void? The Bullet Cluster is a famous example referred to in this comment thread, but it's far from the only example.

As a non-physicist, observed dark matter gravitational lensing really points to "there's more gravity than we expect" rather than "gravity works differently than we thought" for me.
"Dark matter is a form of matter..." is a definitive statement, but you can't point to a single example of a direct detection of dark matter. It's quite possible the hypothesis is wrong.

The article, and the OPs aren't saying we shouldn't explore these hypotheses. They're just pointing out that they are, well, hypothetical. We should be cautious of talking about these things definitively as though we know they exist.
For the environment it certainly is.
I just cannot comprehend how there are thousands of predatory apps on the store and these apps get banned.

Aside from that it should highlight problems with app stores as a model for software distriubtion in general, although I don't have much hope that this will happen in the immediate future.

That there even exists such a rule is ridiculous and unacceptable in my opinion.
"inordinate amount of energy"

It's comparable to what a single hydro dam like the Three Gorges Dam can produce. Don't fall prey to the scary comparisons BECI employs to mislead its readers.

Global warming is critical, but there are other energy wasters much, much bigger than Bitcoin miners.

Besides, as it's been said many times, miners tend to use renewables since they have become cheaper than fossil fuel power plants. A recent paper by Stoll et al. estimated CO2 emissions as being comparable to what a single city like Las Vegas emits: https://mobile.twitter.com/zorinaq/status/113943906857019392...

It's not a "waste" if the result is a decentralized, trustless, robust digital currency.

And the global warming argument is a many times debunked hoax - if anyone has better use of that electricity, they are welcome to use it, which will make mining cryptocurrency unprofitable. Except in the other cases, the benefits go to the single entity that owns the business, whereas with cryptocurrency every participant benefits from the stronger network. Global warming is caused by using fossil fuels to make electricity, mining crypto doesn't require fossil fuels. There are other ways to make electricity, let's focus on them.
So supercomputers produce nothing useful but the bitcoin network does? In the long term I'm not sure we gained anything so far by all the energy spent on bitcoins. Some people got richer, some got poorer but I've yet to see any benefits for society from bitcoin.
But just thinking of the electromagnetic forces in terms of what is required from them to keep matter together in the context of that same matter effectively expanding faster than the speed of light is... at best weird.
Whoops I apologize, looks like it's only the console prompt! I get that Ctrl+V might be disabled for security reasons, but is there a config flag to enable it anyway?

And yeah for some reason Ctrl+Left/Right to jump around words, Ctrl+Shift+Left/Right to select words, and Ctrl+Backspace to delete a word, are disabled in the console prompt as well (they do seem to work in all the other DevTools input fields I can see). These are pretty ingrained in my muscle memory so I constantly bump into them.

Also I'm on Linux, in case that matters.

> I'm saying when something is open sourced, -the work is done-. You are not necessarily volunteering to work any more. The act of open sourcing something involves no volunteering; it involves giving something away. Likewise any patches you choose to release.

Open sourcing something is also not equal to distributing something for free. I'm sorry for nitpicking, but there's a lot of genuine confusion about this out there.

You can release something with an open source license without distributing it yourself.

The free software movement regards it as a moral imperative to license all software with free / open source licenses, even if you just give the software to your client and never upload it to Github or release it publicly online.

Even if you distribute it, you don't even have to have a bug tracking interface.

Open sourcing is simply attaching a free/open source license to a piece of software. Nothing more nothing less. Not participation in the community, not Github, not issue tracking, not upstream or downstream patch contributions, or volunteering or zero-price distribution or anything else.
It's going to be tricky.

I did some of the "listen" exercises to validate how people pronounced some sentences, and I got a few people who spoke with very strong (Indian, Nigerian, UK, ...) accents. How would you take these things into account? Just average all of them and hope for the best? Not sure how to approach that. I don't think it's very straight-forward. Interesting problem though.

However, you can't do anything if you don't even have the data, so props to Mozilla for starting this.
What we can observe in large cities is that there is a constant stream of new buildings and construction works. The "build once" model works for one building and over one lifetime, but at the scale of a large city, construction work is a constant process.
It's disturbing that people are still praising Bitcoin in spite of that fact that it can only handle at most 4 transactions per second and consumes as much energy as Austria.

Same goes for Ethereum at 15 TPS...
Ethereum is an over-engineered mess of technical debt. It's been stretched way past its original design goals.

All these valuable cryptocurrencies are a symptom of a failing capitalist system. The only reason that they had value in the first place was because the rest of the economy was so inefficient and speculative that they started to look like a wise investment in comparison (especially as a hedge).

The rise of useless jobs is real, this is especially true in the cryptocurrency industry. The amount of human effort and talent which has been wasted on Bitcoin, Ethereum and other overhyped, poorly engineered cryptocurrencies is staggering.

Not only is it wasteful, but this industry is producing a new wave of engineers and scientists who are gullible (hype-driven), unskilled and complacent; a dangerous combination.

Most cryptocurrency projects were created by juniors who had limited understanding of distributed systems and scalability at the time. If Vitalik Buterin had to start Ethereum from scratch today (knowing what he knows now), I think he would design it very differently. But instead, he is forced to support the existing network and protocol even though the only real way to fix the project is by starting from scratch with a new foundation.

It's like if you start building a 1-storey apartment and after you finish, you realize that you actually needed a skyscraper; but instead of starting again from scratch, you decide to re-use the existing building foundation with the same investors, same architects, same engineers, same builders. You even allow the existing tenants continue to live inside the house while you continue building on top. It's probably not going to work because you don't have the right foundation, your team doesn't have experience building tall structures and you don't have any experience leading projects of such complexity - The fact is that your odds of success are extremely low; your foundation is probably not strong enough, your team is probably not smart enough and not adaptable enough and you, the leader, are probably not humble enough to accept reality; so you will fail to take the necessary steps to fix the problems.

Not only that, but YAML as configuration has some pretty significant drawbacks in that the natural (but disastrous) trend is towards using text templating systems to generate YAML files. It’s also a bit difficult to parse or write correctly.

Yes, you “shouldn’t” use text templating systems for YAML and you “should” use well-tested YAML parsers and emitters. But I am very skeptical here, especially given that this wonky format is supposed to be the interface between teams that aren’t talking to each other.

Yep, taxi drivers are strangers, which is not desirable for people who need to be chaperoned, and in worse cases it puts those passengers at a risk of being taken advantage of (like being charged an unnecessarily higher fare, or not getting their forgotten belongings back.)
- Children love to ride bikes when it is safe to do so, from personal experience.

- If you keep some (inverse of most) streets open to a small amount of traffic (Like Barcelona's superblocks [1]), the elderly and those with disabilities are still mobile.

- Why is privacy needed when travelling? Do you require a private enclosure around you when you are walking? I've met many interesting people from all walks of life while cycling and on public transport that I wouldn't have had the chance to meet otherwise, just like I meet people when on foot. Car free streets provide many more interesting street restaurants/businesses for such activities you describe.

- Travelling with the whole family on a train or cycling is pretty good. For example, in Sydney the seats of most of our trains flip so you can have up to 6 people facing each other.

Though I am excited for self driving cars because we won't need so much parking!

I "believe" in global warming, but I wonder if we had a season like 1886 again if it would be trotted out as sure proof of global warming?
For sure. Study the literature of your subject. The point is, what do you think about automatically when you don't focus on a specific task? My expectation is, that people who are great at what they do continue to think and daydream about their work. When I read about philosophy (or related subjects), I'm continuing to think about it for days or weeks. That doesn't happen with tech, although that's my daily business.
Ask Google, Facebook, RedHat, Canonical, SchedMD (who produce Slurm).

Tons of open source software is being created by professional employees of companies today. It's not some hypothetical, this is today's reality.

And it's mostly about profiting from related services, paid support, training, consulting etc.

I realize it cannot work the same way for some minor app by a tiny company and it does create wrong incentives sometimes (you need to make things just complicated enough so they need to hire you for support and training, but not so complicated that it's unusable).

(By the way, nothing forbids you from charging for the software, source or binaries, even if you license it under a free software / open source license. "Free" is a catastrophic naming choice, as it doesn't refer to zero price. It is true, though, that anyone who buys it once can then redistribute the software for zero price, so you'd only get money from people who buy directly from you, instead of obtaining a copy at zero cost from somewhere else.)
Science. I can't take any study seriously until it's been replicated at least once, preferably twice. Does anybody know if there's a search engine for replicated studies?

How do you do time tracking in your team?
The number of stops is probably less important than the distance traveled by food. Towns or small cities can have food produces locally. In large cities, food has to travel across the city, and on top of that it has to travel across the space required for farming.

This is a non-concern now of course, but in a world where we want to reduce transportation at scales serious enough to fight climate change, large cities will be a liability.

Cars are expensive. Cars are extremely expensive to park in the city.

I don't think anyone is arguing to ban cars in outer suburbs without sufficient buses to the local station.

I imagine most inner city drivers are quite wealthy if they can afford parking there.
I think my comment is reasonably clear as it stands, if you don't intentional try to distort it.

Your style of argument (including the ad hominems) suggest to me you're neither interested in an exchange of ideas nor in a civilized conversation, so I don't think there's a point for me in engaging any further.

> The cost of energy is minuscule compared to alternative means of achieving the same: vaults, guards, banks, lawyers, etc.

Is it though? Gold in vaults easily outstrips the value assigned to all bitcoins and I doubt these vaults use even 1 Twh/year. Vaults are only environmentally expensive in construction. And since we have a surplus of vaults and bunkers (from digitization of stock trading and the end of the cold war, respectively), the only cost is protection. A few guards and some cameras and high security doors can protect >$10mio worth of gold, probably not using more energy than a few households. Managing a farm of ASICs for Bitcoin generating that amount is probably more labor intensive.

Good to hear a sane voice here. It's weird how people are able to convince themselves and others they can just not take a position. As if that is not an position in itself, usually supporting the status quo and conventional morally of the time.

Space does get bigger, but that's separate. What eternal inflation is claiming is that some fourteen billion years ago there was a false vacuum collapse, and we're living inside the bubble that resulted, but said bubble is itself still expanding.

It won't ever get anywhere, since space outside the bubble is inflating much, much faster than inside. It means there's a border to our universe, which is expending at lightspeed, but it's far outside the Hubble horizon and thus entirely unreachable.

Huh? Am I missing something obvious here? Plenty of databases support ACID guarantees across multiple machines in a cluster. FoundationDB and CockroachDB come to mind, but I’m sure there are others. What you’ve built is cool, but I’m still confused why existing tools aren’t good enough.

From the Cockroach documentation (source: https://www.cockroachlabs.com/docs/stable/transactions.html )

> CockroachDB supports bundling multiple SQL statements into a single all-or-nothing transaction. Each transaction guarantees ACID semantics spanning arbitrary tables and rows, even when data is distributed.

I don't know the history of the U.S well enough, but McCarthyism ended in the 50s, the cold war started immediately after the world war II against communism, so I can't really say U.S. was radically different from now.

One thing worth noting is that fascism (and neo-fascist/nazi groups) was anti capitalist, but not (of course) marxist-socialist.

They have some common ideas, the nationalization of the means of production for example, but it ends there, they aren't against social classes, they aren't against private property, they are simply against free market.

If for Marx communism was the goal, for fascists the goal is complete autarchy.

I would add neo-fascism to the list of anti capitalist movements, even though I sincerely hope they'll disappear ASAP.
Ask HN: How much time do you spend on deploying your ML model?
Hi. How much time do you spend on deployment of your ML models (e.g. to web as an API, to Android, iOS, etc.)?

I recently had to deploy a rather simple NN to web and Android and it looked to me like a boring, repetitive activity. For web, it was somewhat okay with copy-paste input preparation, create Flask endpoint, containerise, create instance, etc. -- I just wanted the damn model to be accessible from the outside of my computer, but it took around an hour. For Android it was a complete nightmare, since Keras transformations I've done on my input image are not ported (or I'm not aware of it).

Right now the share of the world economy running on Bitcoin is negligible, yet its energy consumption is relevant. If that share became consistent, the price of Bitcoin would increase by many orders of magnitude, and mining bitcoin would become more and more competitive in relation to other uses of energy, and would increase in tune - that's why I say inordinate. PoW is just unsustainable by design.

Even better, Malware can (popular malware doesn't so far as I can see today, but could if other methods stopped working) straight up lie in SNI and in the old TLS 1.2 plaintext Certificate message, and produce plausible yet entirely misleading results in your inspection apparatus.

A real client expects the encrypted parts that follow Certificate to match up and should abort if they don't, but malware is under no obligation to do that, and a 3rd party which can't decrypt the rest of the handshake won't know e.g.

Malware client: SNI for bigbank.example (knowing bigbank will have been excluded from snooping rules at the target)

Malware C&C server: 100% Legitimate Certificate copied from bigbank.example

Malware client: Cool, let's continue with encrypted setup (ignores the pretence that this is bigbank.example and now communicates with the C&C server undetected and encrypted knowing the logs will just show "bigbank.example")

"Security" products can't protect against this without snooping each and every single transaction, but many will be deployed by ignorant/ well-meaning people who don't understand how this works and thus that the products can't actually do what they appear to offer to do.
