"The world's biggest lithium-ion battery — built by tech billionaire Elon Musk's company Tesla last year — has survived its first summer in South Australia's mid-north."

"And according to a new report by the Australian Energy Market Operator (AEMO), it's outperforming coal and gas generators on some key measures."

"AEMO says the Hornsdale Power Reserve is capable of charging at a rate of 80 megawatts and discharging at 100 megawatts."

"It has a storage capacity of 129 megawatt hours."

"That means it could operate for about 75 minutes at full capacity."
Cloud computing gets cheaper all the time, why should you commit to spending a certain amount of money? This seems like just another way for AWS to increase vendor lock-in and profits through making complicated payment structures that make people believe they're better off.
Based on whether or not they happened in the UK, which is the subject of this discussion. Perhaps I missed some, but as far as I can tell only 4 of them happened in the UK.

Sounds like too many places are willing to pay young developers too much. Why pay a third what they pay you for an order of magnitude less value?
You're correct, that's not how most flows are implemented. But it is the new flow enabled by this device.

For your AWS sign in obviously it won't need a fingerprint and so it'd be kind of silly for the demo to be "this more expensive product works like the older cheaper product you already have" they wanted to show off the new feature which is the "resident credential" user verification mode.

It would be neat to see a more in-depth analysis on the success of these X for Y startups vs non.

A big reason for X for Y, besides simplicity of explanation is...

X is usually a novel NEW process -- or way of doing things -- that either became only recently possible , or was recently demonstrated as successful.

Suddenly it becomes clear that this NOVEL new process can be applied in other areas.

Uber and AirBnB opened up efficient sharing of expensive resources that were underutilized prior.

Now, the natural next step is:

"What other expensive resources are underutilized?"

Boats?
Commercial retail or wharehouse space?
Tractors and heavy equipment?

So, in the early stages of rolling out a newly realized novel process, it seems impossible that the process should not expand to a number of similar problems.

Until the low hanging fruit is all gathered.

Uber for Y, for example, seems to be only in its VERY EARLY stages.

No doubt there are MANY Y's out there to roll out the Uber model to.
Yubico has released open source programs to manage YubiKeys.

https://github.com/Yubico/yubikey-manager/

For example, it is possible to configure whether user interaction is necessary before encrypting:

ykman openpgp set-touch enc off

The program will probably gain support for fingerprint configuration when the new YubiKeys are released.
Question: what happens to the solar energy when PVs are disconnected? I presume reflected or absorbed as heat, but is a PV under load cooler/less reflective?
In this case, the behavior of the former Twitter employee makes him appear unlikely to be innocent.

He tried to forge an invoice while an FBI agent was in his home:

“ According to the complaint, Abouammo created a false receipt using his home computer during the interview to show a $100,000 payment received from Asaker to disguise the payments as media strategy work.”
And what happens when a solar farm goes bankrupt? Its major operating overhead is servicing the loans for the initial capital cost. So all that will happen is that the bank will take possession of the solar farm. It will still be producing cheap power, and it will now be owned by an organisation with very deep pockets!
Do i remember correctly that Chrome wanted to deprecate HSTS about a year ago?

What happened with that?

Also from what I can tell their argument is actually about replacing all uses of `=` with something else, and there's no reason the something else couldn't be `:=` (which has plenty of prior art, even if it has fallen out of favour recently).
You really want to rely on such assumptions for security?
To counter balance your point : the original Volvo emergency braking system in the car saw the crash and wanted to brake 1,3 seconds before it happened.

So Volvo engineers didn't think at all like you do / say. Their system was 0,1 second faster than Uber at detecting it, 1,1 seconds faster if you factor in Uber active suppression, and it would have braked 2,1 seconds sooner than the Uber did.

Why didn't it? Because Uber deactivated it's braking ability.
> pretty easy to use statistics to determine a common food or infection source.

It's getting harder. Privacy protections mean this type of analysis across hundreds of millions of records isn't really possible anymore. Without hundreds of millions of records, identifying "people who drank milk from Mr Smiths farm in 1969 were 200% more likely to get parkinsons 45 years later" couldn't be done.

Yet if Mr Smiths farm had cows with some as-yet unidentified prion disease, this is the only way we'd find it.
Well if your work contract allows "not asking for permissions", why not.

What you're describing is known as a smart grid in the industry (https://en.wikipedia.org/wiki/Smart_grid).

I can't speak for other countries but Australia has quite a few initiatives for progressing toward a smart grid but it simply takes time.

Here is some info:

> Anyone who underpays their property taxes ends up with a lien on their property.

Not in the age of Prop 13, sadly.

> When you describe the rise in property prices as a result of the tech boom as an ‘unearned windfall’, it sounds like you are opposed to the appreciation of assets altogether.

It's not a question of opposed or not. Sometimes some people get lucky and others don't, that's a fact of life. Houses appreciating at a normal rate is one thing, but SF has gone up massively, and the vast majority of those who benefited from that didn't do anything smart or virtuous to earn it, they just happened to pick a city that happened to become a lot more valuable. (Maybe some people genuinely did economic analysis and decided that SF was a smart place to invest in, but realistically they're a tiny minority).

All of which is fine. Some people picked one city and their houses have gone up 4x, others picked another city and their houses have gone up 10x, even though neither group of people worked more or less hard or are more or less deserving. That's life, that's fine. But we shouldn't be giving a tax subsidy to the people who were already lucky enough to have their houses go up 10x. (Indeed, if anyone should get a discount on their property taxes, it should be people whose land values haven't gone up much - the ones who've been unlucky).

> What would count as ‘earned’ in your estimation?

Labour income. Things that require active involvement. It's fairly standard terminology, no?
Oh many, so many times in my life I wished I could explain my gripe using such a simple term.

It can be but often it’s not, particularly when people are into cars.

Things like handling, the interior quality, noise makes a big difference to some.

Would I replace my BMW with a Toyota if it handled as well, had as good engine, had a better screen and computer system and such a well calibrated gear box - of course. And Lexus IS getting close.
> What Amazon is doing sounds more like stopping to be an open marketplace, depending on how hard it is to get approved. That's a solution, but at that point they are just another Target or Wal-Mart.

Good. If I buy from Amazon I want to buy from Amazon and Amazon alone. I'd never have considered buying Apple products via Amazon until Amazon recently became the exclusive seller of Apple products on their platform.

Don't get me wrong - I'm happy to buy from other reliable non-Amazon shops. However a seller that relies on Amazon or eBay but doesn't own/offer a trustworthy first-party store under their own domain, often feels cheap and like a someone willing to cut corners.
These are the most stable countries in the region because they are the only countries in the region allowed to be stable. Iran is by almost any measure a better country to live in than Saudi Arabia, except that it does not do the bidding of the US, so it is getting illegal sanctions imposed upon it, almost officially recognized industrial sabotage, it is cut off from world banking etc.

Note: I'm not claiming Iran is some tortured paradise. It is still a brutal regime, with horrible regressive views and which is acting tyranically towards its own population. It is much worse than Israel in that regard (though at least Iran is not waging a war of aggression on a neighbor sattelite state, and defying UN resolutions and international law in doing so). But it is still significantly better than Saudi Arabia in almost everything to do with human rights.
>(i.e. users were already heading to that site, the ad was just there as google tax)?

I saw research which indicates that it is a good idea to pay the google tax. Users heading to your site may get distracted by your competitors or other stuff. The more ads are shown the less organic results (which are not easy to control) are visible without scrolling. In best case, the search results are showing your ad immadiately followed by your organic result, making up the whole screen real estate. Wherever the user clicks, he ends up on your site. Also, cost per click tends to be lower for brand search terms.

I've always taken this approach. Before I wrote KSCrash [1], I didn't have a CLUE how crash managers worked. In fact, here's my first implementation of a crash handler [2], which did EVERYTHING wrong. I ended up innovating a number of things that were thought impossible at the time, but are commonplace today (such as tapping into the Mach error handlers).

It was the same for the Musashi 68000 emulator [3]. Before I wrote this, I had no experience with emulation other than playing one of the Pac Man emulators in the 90s, and yet the first iteration outperformed the x86 assembler core in Mame by 15%, and thus replaced it in the next version.

6 months ago, I didn't have a CLUE how ieee754 floating point worked. Now I've developed a floating point compression algorithm [4], which is being used in Concise Binary Encoding [5], also something I've never tried before.

You absolutely should try diving into things before you know what you're getting into. Even if it doesn't turn out the way you wanted, you're in for one hell of a ride, and what you'll learn is priceless.

I can definitely make the results public as it is a server we purchased to test before a bigger purchase.

I will try to do some basic perf tests as well along with our workload specific tests.

I plan to share the results as. Blog post here - https://aravindh.net
Not sure if that's still the case, but a while ago as an AWS customer with premium support you got a very extensive list of phone numbers of AWS representatives to escalate issues to in case your technical account manager or his supervisor were not available in emergencies. While I believe the list didn't include somebody from AWS' C-level, it went pretty high up. As I customer that felt very good, because it gave us the confidence that there is always somebody available in case of emergencies.
But the intuitive meaning of = and the actual Python meaning of = are completely different. Which is the entire point here.

Indeed, there's no intuitive of "the box that is referred to by the name on the left shall now contain the value that is the result of the computation on the right" since serious humans have had no need to express the concept.

Most people who code in Python have no idea what they're doing. It's all magical incantations that they fiddle with until it gives the output they want. That's why python prohibits

if x = some_computation()

since if it permitted it, everyone would be all wtf. But the number of people who can gather that "sequence of symbols taken as a unit" has some arbitrary new meaning almost certainly significantly exceeds the number of people who can gather that "symbol traditionally used for signifying equality" has some arbitrary new meaning.

And, at the very least, if you see some incredible incomprehensible sequence of symbols you can ask what they mean. It is, however, necessary that you have not unknowingly misunderstood what the symbols mean before you can seek clarification, since no-one ever asks for clarification for something they fully but incorrectly understand.
When I write stuff that's not in my native language I really do want feedback to help make the article better, and to improve my language skills. On that basis I offer the following observations:

==========================================

"It's July 20, 1969 ..." The rules for apostrophe or not apostrophe in "its" versus "it's" are something I need to run through my head every time.

"Michael Collins" ... it's a bad thing to misspell someone's name.

"Over there" (although this sentence doesn't really make sense in its current structure ... it feels like a translation that's too "word-for-word")

"Apollo 11 was the first moon lander to carry humans to the moon." This is not technically true without qualification. Apollo 10 had a manned moon lander and went to the moon, although it did not land.

"1,45,000 lines of code were written" ... I don't know how many lines that's supposed to be.

"Margaret Hamilton" ... again, spelling names correctly is important.

==========================================

There's a lot more,but let me say that this was a reasonable summary of a fascinating event, and I thought it was an enjoyable quick read.

If the author keeps writing, I'm sure they'll improve, and stories like this always have a place.

Same, I've never worked anywhere (other companies, or my own after the first couple of years) where you could really be "done". There was always more to do if you finished the critical path tasks.

One of the most important changes for me, going from normal employment to self-employed, was no longer being paid by the hour. I don't know what it is about it but when I'm on the clock, all I can think about is the clock. I love being rewarded financially for being more efficient than expected and finishing early, and I love having the liberty to take a bit longer (and accept that it's not going to earn me more money) to get the job done right to my own satisfaction.
> Take an audience of X people. Divide them in two. Show ads to your test group, don't show to control. Watch your business grow and gauge the lift between the two audiences.

So advertising industries use people as guinea pigs to study the "real effect of their ad dollars". No ethics committee, no informed consent, nothing.

Yet another reason to block all ads.
First time hearing about Shadow. Their site doesn't mention anything about usage limits, so it sounds a bit too good to be true. Do they have any usage limits in practice?

Agree with that, but that's better represented by modelling poor agents as systematically transferring small portions of their wealth to the rich rather than randomly losing or winning large portions of wealth.
> There are accusations that a teacher sexually molested somebody, but the investigations never went anywhere; do you hire that teacher? I don't think parents are about to blame you for not hiring that teacher.

That has bad externalities. In particular, you'd be creating perverse incentives for people to make accusations against those they dislike (or threaten to do so), a very asymmetric weapon that benefits liars more than anyone else.
Can you point out where Microsoft recommends that you do nothing besides if the user is using "Azure SQL Database and Data Warehouse" (and that's because mitigations are already deployed on their cloud services)?

Microsoft has deployed mitigations across all our cloud services.

Those giant cooling towers are pretty expensive and the water to run them can cause significant damage to the local ecosystem if it raises the temperature of whatever water body they draw from. It's a lot easier to just turn off the energy sources (such as solar) that can be turned off without ill effect.
Are you implying that the BDS movement is anti-semitic? That would be an extreme claim, which would require some kind of evidence. Being against Israel's actions towards Palestine, which is far and away the most important topic covered by the BDS movement, is in no way an anti-semitic sentiment.
They are true in a sense that they come from the natural state, not inflicted by external substance.
I don't understand how your conclusions were reached from my post.

My blog's content is natively shown inline with other content on Pleroma. To a Pleroma user, it and responses seem like all other native posts and interactions. They can click its ID to go through to my original blog. There, everyone sees my blog and its style, as well as the same responses as native comments. Back on Pleroma, those users can boost it and share it with others (their followers). Virality achieved. No further engineering needed from me to enable that.

That's federated social networking. Imagine writing a YouTube comment from Twitter's interface and your Twitter account. In this case, my blog's content -- not just links -- natively pops up in followers' feeds when I publish something. And since ActivityPub is built on and compatible with RDF, this could be extended to all sorts of domains and interactions.

AWS has redundancy built in with health monitoring and auto scaling groups etc. The training covers all this.

Women in power: Why the glass ceiling still exists?
I haven't looked into WiFi, since this was about static magnetic fields rather than fluctuating magnetic fields, although I have read about the increased incidence of gliomas (a type of brain tumor) caused by cell phone usage. Of course, that only happens when you hold a wifi source up to your head constantly. For this reason, I don't think that wireless headphones are a good idea.

One odd thing I've come across lately are accounts of the effect of MRI magnetic fields on depression. https://www.scientificamerican.com/article/do-mris-treat-dep....

Since ECT and other forms of brain damage have been shown to offer temporary relief from depression when endorphins are released in response to the damage, I wonder if MRIs have a similar effect.
Jobs (e.g. uptime checks, payment processing, sending emails) are added to the job queue (Redis) and background workers pick it up from there, and churn through them asynchronously. Most of the work happens in the background, so in my case, Redis is a critical piece of infrastructure.

Ugh. This upsets me so much, humans are the worst of the animal kingdom :(
It's inevitable and a direct consequence of the labor system that we live in. The internet makes it worse but its not the problem of the internet, its a problem of the system.

In our labor system, a small number of individuals are by definition going to be payed, as employees, a small amount of the value that they add in order to make their boss wealthier.

Over time, the employees get paid a constant amount of money that they need to spend for living expenses, but the employer wealth will compound and accumulate over generations.

It's a system that comes directly from medieval serventry, designed to concentrate the wealth in the hands of the noble.

Take for example a large surface supermarket, with 100 employees making minimal wage. If those same persons would each own their small family shops and serve the same amount of customers, you would have 100 families well off making way more than minimal wage.

Serve those same customers through a supermarket, and most of the wealth will be concentrated in the hands of the supermarket owner, while the employees make only scraps.

Horses (and other animals in training) are problem-solving agents. To teach it something, you pose problems to it that it can figure out.

Especially for dogs, you pose a problem in the form of "How do I get a reward from this Hooman?" And by adjusting the difficulty of the required solution a dog understands what you want.
