That's incredible.

Normally I walk into these wunderbattery threads expecting to heap reproducibility scorn (we're still waiting for solid state glass batteries, and will in all likelihood be waiting forever) but pathways to reproducibility aren't something I'm used to in battery vaporware.

I'm actually excited for battery tech, which seems weird given all the disappointment over the previous decade or two. Feels like being excited for another cancer cure in mice.
Cooking spray is just oil in a spray can, usually Canola.
The elephant's foot is quite deep under the reactor in a lower level of the complex. So I don't think it specifically is any more or less safe since you have to go to a lot of effort to get near enough for it to hurt you.

The New Safe Confinement has a different purpose - to stop radioactive dust and debris from the reactor itself (a bit higher up) from spreading into the nearby area and being spread by the wind in case the hastily constructed original containment structure collapses (they are going to remove that old structure now the NSC is finished so that doesn't happen, I believe).
I took the bus to work from marin to san Francisco. I did so even though driving is faster because (a) in the morning, i could do work the moment i got on the bus (free WiFi) instead of shouting at the driver in front of me, (b) because i started work earlier, I could leave earlier and (c) in the evening i could browse the internet and watch Netflix on my way home. The extra 15 minutes i spent because I took the bus instead of drive was spent in luxury essentially.

A lot of applications would be a lot better if all their functionality could be covered in one page with a bunch of buttons.
As I see it, the expectations I'd have towards a mobile note-taking tool (like Google Keep) are different enough that I think it should be a separate program. Folder structure would be fairly cumbersome to navigate on a cellphone, and few keyboards make it particularly easy to type the symbols that control Markdown styling; on the other hand, you'd probably really want solid support for shopping/TODO lists and the like, for which Google's tiling organisation paradigm seems very useful.
Maxwell's book on electromagnetism, it shows his hindsight perspective on interpreting the phenomena. One can look at the papers and works he wrote that led up to it, but they are full of detours and unbalanced attention with small dead ends. When he writes his book he tries to convince the audience of his time in one comprehensive work.

What I love especially, is that he is very careful and systematic about his conclusions, splitting up in cases, instead of simply producing the solution and then proving it is a valid solution.

For example he does not assume that every point in space has a single value for total potential. First he describes how it is at least theoretically conceivable to follow a path and observe the total potential to vary continuously, and arrive back at the point of departure but end up with a different value of the total potential. He is effectively describing the possibility of wormholes (which didn't bear the name "wormhole" yet back then), or "charge without charge" (think Wheeler). But after this part of the book he assumes that the total potential is singlevalued (not because he proved so, but because describing physics in spaces with complicated topologies is far from straightforward, even today).
Hookers make good money too.
He was never convicted of trafficking.

And there are no public records that indicate attendees of his events were aware that women were being paid or forced to have sex with attendees.

Without guessing the mass cannot be "just as lethal" now as at any point in the past. Its lethality comes from decay of unstable isotopes. Radioactive decay has a half life so radiation inexorably falls with time and lethality necessarily falls with it.
"Organic" with respect to agricultural goods is a term of art defined by law.

"Inorganic" is not a legally defined term with respect to agricultural goods, nor is it a scientifically meaningful term because carrots are made of organic materials (as "organic" is used scientifically). Thus, calling a food product "inorganic carrot" would either be fraudulent or deceptive under US and EU laws.

On the other hand, it is possible to have a "meat carrot" like Arby's did this summer, which consisted of carrot-shaped meat.

And it's certainly possible to have an iron carrot or a plastic carrot. Just not as a food product.

Context matters.

The Lemote Yeeloong rang a bell, since it's one of the few computers that's "built on free software from the BIOS up" that was recommended by Richard Stallman [2]. Glad the effort to run this is still going strong and supporting the latest version of OpenBSD, released in May!

Was wondering about if you could put a liquid coolant loop from the battery to the charging socket on the car, then have a heat exchanger in the plug and run water to and from it using a jacket round the cable, so you can have a rapid charge that also helps heat your bath water.
Why not rotate conductors throughout different busses? A conductor gets on at one stop, checks everyone's tickets (so they may end up covering a lot of their cost initially in fines), then get off a few stops later and catch a bus going the other way.
I bet there are a few good businesses around building type hinting for large rails codebases, both for use for profiling, bug detection, and as an editor-agnostic backend. Ditto for large React codebases. I don't think these are large businesses, but look at eg Sidekiq. There's probably a very nice living for a handful of people who get to do interesting work.

NB: people on HN are oddly cheap. From the perspective of someone who makes payroll for 10 engineers, I can spend $1k on something like that basically because a senior engineer asked nicely or thought it might be useful. $5-$10k is definitely in scope for useful tooling. (Prices per year because I understand that if the authors can't make a working business, they stop offering me the X that I'm buying). Also, please make it work with vim. Pretty pretty please.

And there are probably good industry jobs eg at Dropbox for python or rust, etc. Basically, find a large company with a big investment in a slightly-off-the-beaten-path programming language, and there will be very interesting work.
Yep the 400 bus does! It goes via Mascot Station and then via UNSW and Randwick to Bondi Junction.

A good hack is getting off the train at Mascot, walking across the road and catching the 400 one stop. They come every few minutes and you save the airport train station fee!
I don’t know, but does it matter? If an employee group understands how much they are worth, and can get more benefits commensurate with that worth, then I applaud them.
I didn't grow up rich or culturally connected in New York. I went to one of the few universities in the US where you can pursue a dual degree in a conservatory level music curriculum and a top level engineering program simultaneously. While I now largely play music recreationally, it was absolutely my favorite experience in college and I cherish that life experience.

Her points are mostly sour grapes and throwing shade at the broader industry/community imho. Does it have diversity(?) - it tends to be very, white, asian, and jewish. Does it have a diversity problem? Perhaps, but at the same time, I don't think diversity will some how 'save' classical music. Ultimately, I think classical music more generally in at least the US is more diverse, has much broader engagement and diversity and gas more appreciated/exposure as it pertains to marching bands and football programs. It's a bit lame admittedly, that music can be so dependent upon sports for it's relevance but I also think one of the most fundamental issues with classical music is it's notion of performer/audience. Many people love to play music as it's a satisfying and communal endeavor, but so much of the classical world is focused on aspirations of getting paid to play for audiences. I hope that one day there will be a bit of a mental shift that reconsiders what about playing in a band or orchestra is so magical and recenters the whole thing on the participation in making art collectively instead of trying to exist merely for the pleasure of an audience. I think it would be a welcome realization that would allow the classical realm to refocus and reengage with society in a more relevant way.
I think this lunch may have been eaten – Via now has a contract to do routing and location reporting for the NYC school bus system.
Dang, this looks so close to being what I’ve been looking for (and failing) in terms of an “organizational” manager. I find that not a lot of tools let you go from macro to micro planning and back very easily and efficiently and are either long term focused or daily/weekly focused.

If I purchase lifetime access will that include future updates? Will I be able to retrieve all my data if you stop offering the product?
Of course, that begs the question

Begging the question is a logical fallacy.

If you can do your job on a train on your laptop, why the hell are you traveling to an office in the first place?

Potentially there are some, but not all, parts of the job that can be done without face-to-face interaction. Or potentially there are parts of the job that can be done without face-to-face interaction but would still benefit from being in the office.
TFA does note:

> Born of human error, continually generating copious heat, the Elephant’s Foot is still melting into the base of the Chernobyl nuclear power plant. If it hits ground water, it could trigger another catastrophic explosion or leach radioactive material into the water nearby residents drink.

I had never heard that it was "still melting into the base of the Chernobyl nuclear power plant". Given that it's only 10% as radioactive as it was initially, that seems unlikely.
If no one is driving, it makes citizens do more of the work.. in a crowded bus, a group of normal people could throw the asshole off. Eventually, the assholes won't ride the bus.
I’ve never tried pure, I’ll give that a shot.
You are completely correct, thank you.
Express bus lines can also work in a similar role: You end up taking a feeder route for 10-15 minutes that is barely faster than cycling[0], the switch to an express route where you have one or two stops and is equivalent in speed to driving. Obviously capacity is lower, but it's a lot cheaper to setup a bus route than rail route.

[0] Even in London where buses stop every few hundred meters they are faster than walking (unless there is a lot of traffic). How badly designed is GPs system?
This doesn’t raise the smoke point. The solids in the butter will still burn at the same temperature regardless of what it’s mixed with.
But why rewrite a 4M LOC system that works in a new language, just because of a new shiny? How do you justify that from a business standpoint? Especially when your current engineering staff are already experts in the currently used technology, but likely novices or mediocre in Rust? Do you freeze new features during the rewrite? Do you develop new features in parallel? Rewriting, just because, Rust, is a waste.

Sure, you can hire new talent that knows Rust, but how long for them to pick up the relevant domain knowledge? How long for the existing talent that has the domain knowledge to become equivalently proficient in their current tech stack?

Plus, with a rewrite, you risk falling ill to second system syndrome.

Economically and from a practical engineering standpoint, it seems to me that Dropbox is taking a very pragmatic approach. Gradually make working with the exist code easier rather than throwing the baby out with the bath water.

I'm not hating on Rust, but this fervor to rewrite everything in Rust is obnoxious and often short sighted, in my opinion. If you're talking brand new, green field development, by all means, it should be considered.
I read a little bit about this a while ago. Is there still a way to buy these? I've heard great things about systems development on the MIPS platform but haven't had a great reason to invest myself in learning the architecture. Any opinions from others on that subject would be appreciated too.

But for everyone to believe it, it has to be an at least reasonable belief. Luckily, that's a low-ish bar with fairies being a somewhat common belief too (I have no numbers but want them...). So those engineers for those same good faith reasons install redundancies. Heh, it's a balance that may or may not tip positive (everything working) or neutral (nothing happens) or negative (everything sabotaged by an enemy actor) and we'll only know after the trigger has been pulled.
That is an extremely unconvincing article.

> Not even close. We used an infrared thermometer to measure the temperature of food (here, Brussels sprouts and garlic) being sauteed in extra virgin olive oil. ... As you can see in the video below, the oil and the food did not exceed 180⁰ F.

I watched the video. Indeed, the Brussels sprouts cooking in oil did not exceed 180F. No kidding — wet food, e.g. Brussels sprouts, won’t exceed the boiling point of water until it’s quite dry. But this is entirely missing the point — the oil in the pan is considerably hotter, hence the sizzling.

I'm not sure you're actually reading my message. A bluff at the rear of the car is terrible for aerodynamics, but having a rounded shape is inconvenient for the interior and storage. A compromise is made where you have a slope and then a bluff. The prius has this slope and then bluff. The flat surface is still bad for aerodynamics, it is not there to benefit them.

Also stop just googling for wikipedia links then coming back with information you've only just learned. It's ok not to know everything.
What do you mean by "sub-channel"?
Second bullet point: recommend using “strong opinions weakly held” (https://medium.com/@ameet/strong-opinions-weakly-held-a-fram...).

Always be ready to review any opinion you have in the face of new evidence. In fact, seek out information that will challenge your opinions. But until the burden of evidence favours another opinion over yours, be prepared to hold and defend your opinions stridently.
Just for reference vegetarians are generally "allowed" to eat butter, it's vegans who disavow all animal products.

This isn't as inflammatory as you think it is, software engineering is just a subset of engineering... just like all other engineering fields.

OP is just happy that this can be applied more generally.

In my opinion, engineer is just a term for people who solve practical problems. Which is a huge community of people these days.
How neat! Lovely project. I applied it to a gif, an excerpt from the new Joker trailer, and it created what I think is a neat effect.

Bravo! Ensuring the foundations are solid (and in this instance, going back and doing this despite the product's success) is a great sign that you believe in the product's long-term development. Not just milking it while the sun shines. As a customer, that encourages my faith in the vendor.

EDITED: formatting.
Do you add the butter right away, or do you wait until the pan is hot?

I tend to get the best results if I let the pan heat up and then add butter. That said, I use “earth balance”, which is really oil and not butter.

I cook eggs almost exclusively on my stainless steel pan.

One reason why only licensed taxis can use those lanes is to prevent regular people using them.

If you just needed to sign up to be an Uber driver, and you could use the HOV lane, everyone would do it. Even if you had to do that and pay a fee of $5000/year, there would be plenty of people who could justify that over the time saved in traffic (but probably not Uber drivers).
One way popcount is useful not mentioned in the OP is in the graph analysis. For example, you can use the following

std::bitset<N>* graph = new std::bitset<N> [N];

to store the adjacency matrix for a graph with up to N vertices in N^2 bits of memory. The nice thing is that std::bitset::count uses popcount to compute the number of bits set to one.
This makes some graph operations extremely fast even for a pretty large N. For example, graph[i].count() will produce a degree of a vertex and (graph[i] & graph[j]).count() will produce a number of vertices adjacent to both i and j.
Has this changed on Android in recent years? I remember building a Camera app with a smaller-than-fullscreen viewfinder. I believe I got to set the dimensions of the viewfinder myself, making it as arbitrarily small as I wanted (or even optional?). Perhaps I remember incorrectly. I wonder if things changed.
I think (and may be wrong) they meant conversion of lanes to HOV, but not actually increase lanes.
Anyone know the environmental impact on the rise in vinyl?
Probably so small it's nearly inconsequential but still (to me) a shame to see an increased focus on consuming physical items ultimately destined for the trash bin.
Marin to San Francisco is an interesting example because Marin Transit has next to no idea what the fuck they're doing. My experience over a few decades is that getting to/from Marin-SF on public transit typically takes 2-3 hours depending on how far away from downtown SF and 3rd/Hetherton you're going. If the delta between driving and taking the bus is only 15 minutes you either get stuck in awful traffic or live very close to a 30/70/101 bus stop.

Grievances:

The 101 is a great idea, a limited stop bus from SF to Santa Rosa that can basically camp out in the carpool lane. Except that in their infinite wisdom, Marin Transit doesn't actually time transfers in San Rafael. Unless you live within walking distance of a 101 stop you're often just wasting your time.

Real-time predictions sound great, except that Marin Transit is pairing with the Transit app. For a while was providing completely fabricated predictions. Sorry, you're only going to leave me stranded in the middle of the night once before I dump your app. NextBus has its share of problems too, but the difference is that Muni runs such frequent service you're more concerned with predictions and headways than with schedules. Marin Transit runs such sparse service that you absolutely need to adhere to a schedule.

A zone based fare system sounds reasonable to most people. Unfortunately Marin Transit is not set up to refund overcharges when you can't tag off as you exit the vehicle (e.g. when their own equipment doesn't work). Zone based fares also complicate cash payments wildly slowing down the boarding process. Unfortunately Marin Transit refuses to let people alight from or board with RFID payment via the rear doors slowing down the whole process even more.

The Golden Gate Bridge District (one of the folks Marin Transit contracts out to) leased another ferry knowing that the engine wasn't compliant with California emissions requirements. In their due diligence they never realized that it is physically impossible to retrofit a compliant engine into that heap. It's still not in revenue service.

Historically there have been very few feeder routes because people tend to like to keep the poors out (Tiburon is notoriously bad). So to get from Marin to San Francisco you're often walking all the way out to the highway, sometimes along roads with no sidewalks (I'm looking at you Sleepy Hollow). SMART also suffers because of this. Getting to a SMART station can easily be a 30 minute walk along a route with no bus service.

That said, things don't actually have to be this way. But Marin likes its privilege[1].

What does this comment add to the conversation here?
It would be really interesting to know what the actual profits are and what percentage currently goes to the pilots versus executives and operational costs etc.

Google says they reported $2 billion in profit. Say $300 million was given to 1000 pilots. That would be $300,000 each.

They probably got something like a few thousand pounds pay increase and are feeling like it's not adding up.

I'm routing for the pilots.
