It's a fantastic use of a great resource. It works because Lake Ontario gets pretty deep pretty quickly near Toronto [1]. The drinking water they bring in is extremely cold year-round:

> Three intake pipes run up to 83 m (272') deep and out to 5 km (3 miles) from the shore. The physics of cold water are factored into the design. Water is most dense at 4 degrees Celsius (39.2 degrees Fahrenheit), ensuring that the cooling water removed from the lake bottom will have a consistent year-round temperature at the system’s intake points. The cooling water to be used by the Deep Lake Water Cooling system first goes through Toronto’s standard water treatment process to become regular drinking water.

I'm not sure that there is any other large city in the world that has deep enough fresh water so close that this would work. Such a system would be welcome here in Chicago, but it isn't feasible. You'd need to go 30-40 km into the lake before it got deep enough [2].

Some conflicting studies have found subtle cognitive deficits in users who were abstinent for ~28 days (see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3037578/).

In my anecdotal experience, I definitely notice difficulty with conversations, deep reading, etc for ~2 weeks after stopping. It takes about 1 month of sobriety for me to feel 95% back to normal and 2-3 months for 100%.

Not significantly cheaper, in fact renting would always include the cost of finance, that is borne by the battery OEM.

However, renting allows for lower income earning sections of the society better access to EVs
It kills me that people keep not factoring in long term damage to the earth when they figure out how much energy costs.
Like many people, I worked retail. I never got angry at the security guy trying to let me out the door, but it was frustrating to wait 5 minutes here and there unpaid.

I agree that people should be paid for that time.. but I'm also curious where the line is drawn? I left the city to work on a small town because my commute 5 miles/day was 15-20 hours/week. I suppose you can argue many jobs pay well enough to cover that... But people also work retail in those areas.

An ideal solution would be to spread out the cities -- encourage more remote working (though not like we currently see)... But in lieu of that, where is the limit?

Is employee parking, which is a 5 minute walk to the back of the lot, covered? I had a friend that works at a car factory... If you don't drive that manufacturers car, you park in lot B, an extra minute or three away. Is that any different then being forced to stand at the for to leave a few minutes now and then? (It's not always 5-15 minutes, where this example is a constant).

Please accept this as a thought experiment... Not a criticism against better pay for retail. Everyone deserves the pursuit of happiness.

Corbyn got invited to a Jewdas passover party - it's in literally no dispute that he was against anti-semitism. Labour's systematic problems were under investigation at the time and it was fair of him to not say anything until that investigation completed, however that itself was turned by the press into being viewed as an avoidant strategy, rather than an act of prudence. And as far as anti-semitism goes, the Tories have a much longer and much deeper history of islamaphobia. But at no point did it recieve the same 24/7 press attention, even though many of the incidents were happening concurrently. It was generally only ever mentioned as a sidenote to the Labour anti-semitism scandal. Hell, for a practical sample, just look at this article by the bbc[1], chosen at random (keywords: tory party islamaphobia general election), it is about Tory islamaphobia but the majority of the content present, per paragraph, is devoted to the anti-semitism accusations against Labour.

Even at the end of the year, the Tory party had failed to address it in any meaningful sense[2]

In no way did he get an easy ride. Every single tabloid and media outlet was, on the whole, against him from the start. There was a London School of Economics study a number of years back, showing definively that press coverage of Corbyn was nowhere near balanced[3]. That's not even to take into account that during the election debate, the BBC edited out laughs, by the audience, directed at Johnson's comments[4]. The bbc committed a number of "editorial mistakes" that represented themselves as Tory bias.

This is nice, if the battery spec is standardised and 3rd party battery makers can directly supply to the end users; not just to the OEMs. Barriers to entry for power delivery systems should be brought down as well incl. Smart Power Grids so that startups can enter the space in order to improve power delivery to the end users, at the end of the day economics of owning an EV in India should be favourable for the consumer to invest in it.
Better place, An Israeli startup tried electric cars with battery swapping and failed miserably.

So, decoupling battery from the car and allowing better competition in the battery space might fly. Car makers need not be bothered by the battery tech and can just focus on making good electric motors, since most of the car parts are from other vendors anyways.

However, the decoupling might not be all that rosy as Musk has demonstrated that safety is best achieved with total vertical integration. Even Tesla tried battery swapping but gave up.

This might work really well in 2 wheelers though. The existing bike manufacturers won't have to retool their factories by much to replace the engine with a motor and the batteries can be probably swapped in and out of the under seat space or something like that.
Ask HN: Ratio of “More Complexity” to “Simpler Vulnerabilities”
I seem to recall a rule or law in programming theory (Simmilar to Moore's Law) that states this but I can't seem to find it.

An example would be:

King James I wrote a book about witches and demons: Daemonologie (1597).

http://www.gutenberg.org/files/25929/25929-h/25929-h.html

King James is more famous for the Bible he commissioned. And his treatise on True Law and the divine right of kings. This work of his is somewhat less well-known, I think.

Anyway, it's an amusing read.
So COBOL has no array concept, you have to name every input feature FEAT1, FEAT2 etc? Ouch. I can see why the language is dying out.
I had idiopathic post viral hypersomnia in graduate school, from a bad respiratory infection. For more than entire semester, I could do nothing but sleep for 12+ hours a day. On one occasion, I slept through an entire day. I even fell asleep in the student union once with my laptop in front of me. Needless to say, it wasn't there when I woke up.

No treatment was really able to help me. I was already on adderall, and, while it could keep me upright, I felt like a zombie the whole time. I ended up consulting a sleep neurologist, who basically said they could try "activating" antidepressants (I was already on one), or stimulants, which I was also already on. I don't know if modafinil was a thing yet, but I never heard them mention it.

I thought my life was over. What could I even do with my life, if I always had to sleep 12-14+ hours a day? No doctor seemed to be able to do anything, there was no specific cause, and it's such a rare condition that most people don't know it exists. That, along with the stigma that comes with invisible disabilities (and, believe me, this certainly was disabling) almost made me want to give up.

Then, I started getting better. I didn't know why I got better, but, at that point, I didn't care. I had my life back.

All in all, it was an awful experience, which I wouldn't even wish on someone I hated.

In your example you keep saying 5m as though thats the industry standard sla for security. Thats probably fine. The problem is that if the time is unpaid, theres no balancing force to get people through the queue. If you have to spend more on security guards to get the median time to check someone down to 5m, why would you do it if you dont have to?
There are "tables" in COBOL. My COBOL is rusty, but I know that it can be done.

This is cool nonetheless.

Here in Seattle, when they took down the viaduct along the waterfront, they also decommissioned a tunnel that the viaduct connected to. The decommissioning consisted of leaving the tunnel intact and filling it with ground up concrete from the viaduct.
The limit, legally, is pretty cut and dry: commute time is not paid, anything on site is. If you have to wait in line for security, that's paid. If it takes 10 minutes to count out your till at the end of a cashier shift, that's paid. If you're sent to another location in the middle of the day, time getting there from your normal place of work is paid.

There are a small handful of edge cases that vary by state (e.g., if you have to change into a uniform when you get to work, that's considered on-the-clock in California, but not federally), but not many.
yeah, please don't take this code like is good COBOL code, haha, I learned it just for this experiment.

Boss inadvertantly starts tech-war in donor comments with 'Go Tim'
It is very well thought out on many levels and will also enable electric car markers to enter the market without the burden costs in battery investment. That with competition for battery market thru choice, ability to repair/replace the batteries alone a big thing. So many things going for this, kudos to India, I hope other countries follow suit.

>Also, by incentivizing vehicle designs with removable (and thus swappable) batteries, it makes taxis and other high demand use cases more practical without needing widespread fast charging infrastructure.

That is a big plus as allows more control when batteries are topped up, so enables the ability to shift demand to off-peak usage and equally add grid storage/supply for grid stability thruout the day in a battery form factor that's competition driven price-wise. Lot's of potential here and the first step in that direction has been made.

There's a great deal that can be criticized about the journalism provided by mainstream media outlets (which news is considered newsworthy, which experts are consulted, etc.), but I don't know of any evidence suggesting that the standards for factual reporting have slipped any. The question of who can be trusted to provide analysis is as relevant as it's ever been.

But Australia is not making it easy too. I studied and graduated UQ (but only for a year, so no work for me), and a number of my friends did too and continued to work in Australia. But it's not easy. Most job openings prefer PR/citizens. My friends who got a job can only stay for maximum 2/3 years, with uncertainty related to the point and visa grant system.

If there's a way for me to work in Australia or even get into the work visa stream without spending AUD100k+ on a 2 yr masters + living costs, I'd definitely consider it.

There is a very clear line in that you chose that commute. You can find housing near your employer. You have a laundry list of personal reasons why that housing is not right for you but the fact remains you chose to have those things and commute instead of living nearby and sacrificing those things.

The employer requiring you to do something as a condition of continued employment is clearly, well obviously not, an act that should be compensated for. They could let you leave 15 minutes early to go through security check, they just don’t want to because, apparently, they don’t have to.

I have no doubt that you will find a group of people on the other side of the line there who think employers should have to pay for commuting time and obviously this case proves there are people on the other side of this line who think they shouldn’t have to compensate you for going through security time. However I would guess that the majority of people will agree that hardships you impose on yourself are your responsibility while hardships the employer imposes on you should be their responsibility.

You can use memcpy or unions. No C programmer that knows the language should be casting and dereferencing void* to anything other than char* for portable code.
I think a line can be pretty cleanly drawn at "employer explicitly makes you do it in order to receive your paycheck". Like I wouldn't expect to be paid for my walk from the parking lot any more than be paid for the rest of my commute as that's not actually related to the job site, it's just a consequence of my transport method - what if I was catching the bus, or walking, or I lived in an apartment building across the road?

Conversely - mandatory security screening is something that the company makes all employees go through every day as part of their job - it's no different from any other job task.

Although having a separate further away carpark for people that don't eat and presumably pay for the company dog food is shitty for other reasons. Similar to some clothing stores forcing their minimum wage workers to buy and wear on brand clothing (yes this is a thing).
> The people who keep complaining about it seem more and more like children who just refuse to learn something new and better because they've already stumbled through all the holes it fills.

Systemd apologists always seems to think that anyone not completely in love with systemd, is just refusing to learn something new. Please stop with the stupidity, people have real reasons to hate that shit.

I had no problem with switching to WireGuard, after learning about it, because this is so much better in both use and design than OpenVPN that I have used for 20 years. I had no problem with learning about systemd either, but that is just badly designed software to me.

"Teach Yourself C in 24 Hours" by Tony Zhang (1997) seems interesting as well:

A previous HN discussion on that book:

EDIT: That earlier discussion has an excellent first post. Quoting:

"It bothers me so much that very few books (Kernighan) talk about WHY. WHY. WHY is a variable needed? WHY is a function needed? WHY do we use OOP? Every single book out there jumps straight into explaining objects, how to create them, constructors, blah blah blah. No one fricking talks about what's the point of all this?

Teaching syntax is like muscle memory for learning Guitar. It is trivial and simply takes time. Syntax - everyone can learn and it is only one part of learning how to code. Concepts are explained on their own without building upon it.

[... A list with learning resources the poster finds great ...]

This is learning how to produce music. Not learning the F chord. Teaching how to code is fundamentally broken and very few books/courses do it well."
Portable air conditioners with a hot air vent to the outside are common, but a mini-split like in the post needs a licensed installer or you can face EPA fines.
I've had this same thought before, but where do you draw the line? Should employers compensate employees for time spend showering? Can employees sue for wrongful termination if they refuse to maintain personal hygiene for free? It's a ridiculous example, but somewhere between there and being compensated for performing a function lies the answer.
Exactly!

There is a reason why factories put their punch clock AT THE DOOR.

Workers leave their assigned areas, pass through security, proceed to the punch clock and exit the facility.

Apple is one of the wealthiest companies in the world. The cost of adding an additional security guard and letting their employees exit from the rear of each store is negligible.
Each containment, vessel which produces 50MW of electric power, can fit on a truck. Each site might contain up to 12 separate reactors. That was basically the design constraint so the can be manufactured off site and shipped as one unit.

A regional power company might seek permitting at 10-20 locations. If some locations didn't get a permit or if other locations proved to be uneconomical to produce power at the time of construction, they could just build at the sites they chose. Basically takes the two phase pre-construction permitting and post-construction operating permit which has been killing nuclear power and streamlines it. Because the designs are standard and modular they will be pre-approved to operate.
If someone was peaceful all day and then commits murder, maybe the murder only takes 5 minutes, or 30 seconds ... would you proceed to characterize their day as mostly peaceful?

I mean, mathematically yes, but it points to how this word ‘mostly’ is what journalism teaches is a weasel-word. It renders the statement meaningless.
