This is good to keep in mind although should you ever find yourself in such a situation know that you can still put your feet in a bucket of water. We usually get water from rivers our underground reservoirs so it tends to be cool enough even during heatwaves. It’s perhaps not the most convenient way to cool down but beats death.

Ask HN: Has anyone created a books' bibliography/dependency manager site?
Hi HN,

I would build books' bibliography manager website but more like software package manager (e.g: NPM, crates.io). So people can browse book dependencies either as a bibliography or as an idea dependency of the book.

I wonder. Has anyone created that kind of web app? If not, I want go on that the idea. Is my idea bad?

Thank you.
Maybe google needs a 'downvote' option... but that would suck for anything politics-related, and boots would soon take over that too.
That requires effort. A seize order doesn't, and the cops have already adapted at using third parties like Google [1] to get access to data they should not have in any decent legal system.

A dated claim. They are the same price and not much more to run. In fact, at current gasoline/diesel prices, they are cheaper than conventional cars to run.
Why are Java devs allegedly more prone to this than, say C# devs?

Is it just snark? Or maybe the legacy of using a metric butt ton of reflective magic where interfaces with only one concrete implementation were common, cos Spring?
Because their productivity hasn’t increased as much as that of people with higher incomes. The productivity of surgeons and software developers increased significantly, and so their incomes, while cleaners and factory workers are not much more productive than 60 years ago.
You're misjudging the differences between uranium and gas. Transporting and building a uranium reserve would be relatively easy; maintaining a 10 year stockpile and importing from Canada, Australia or Kazakhstan via a circuitous route are all feasible.

This doesn't work with natural gas because they needed a lot of it and moving it around is capital intensive. The situations are completely different. The energy densities here are wildly dissimilar, and that matters a lot for the economic of building a stockpile.
Tail can do this, too:

This pretty much sums up my experience too. It's been downhill since all the subreddit bans a couple years ago. I miss r/consumeproduct.
The article mainly discusses the (IMO much more interesting) question whether chariots had a similar function on the battlefield to what tanks do today - and comes to the conclusion that no, they did not.
This is like the nerdiest freaking thing. Love it.
All printers suck. I've tried every range and type of printer imaginable over the last 35 years and every single one has made me hate my life.

I just threw a laser out of the window because it got to the point where it would only print one page before jamming. I bought a Canon inkjet and that has lasted a couple of months, but now you have to push each piece of paper in to get it started, and a couple of weeks ago it stopped printing the left side of the paper, so I have to make sure everything I print is only on the right. So, this printer is going out the window as soon as the cartridge runs dry.
And it would result in people not sticking around till the end of the season -> less views.
The general idea is that Reddit has small communities that care about niche topics. If you want to know about mechanical keyboards or looking after a rare pet, you'll find a community there that talks about it. They'll probably ban you if you talk about anything other than the specific topic, you regularly see stern warnings added whenever a topic escapes the niche area and gets exposed to the wider Reddit audience, but that's why they are useful.

Why startup founders should always pay themselves a fair market salary
I don’t know about stark naked - in the northern climes where the fairer complexioned folk roam(ed), furs and wool were a matter of survival.

Anyway, UV sucks, nobody is hurt by minimizing it and supplementing via diet. Hell, in the north the sun doesn’t even rise high enough to be a source of vit D for months on end. You have to get it from diet or not at all.

After this episode, I strongly believe Fed should be ended. They have established a very poor track record on managing monetary policy and consequences and at this point basically have zero public trust. Since Greenspan Fed has been an absolute disaster. They hiked too little, too late. Now there is no such thing as soft landing as they are espousing just as their messaging around the whole transitory inflation thing.

Institutions such as Fed are now completely detached from their mandate and instead under bureaucratic capture devoid of any meritocracy. There is a revolving door between Fed officials and Banks/capital management firms. Bernanke, Powell, Kashkari, Yellen, Brainard - these are poster children of corrupt kleptocracy with revolving door arrangements between Fed and firms like Citadel, Goldman, Pimco. At least Bernanke had economic background. Powell doesn’t even have so. And his messaging has been super confusing with very little forward guidance which constantly confuses the market. I am not sure what qualifications even they attach to these utterly detestable individuals working for Goldman, Citadel, Pimco, and Brooking when they hire them. Oh let me guess, they work for the same people that fund our executive and legislative branch officials.
In Linux, raw disk devices like /dev/sda1 are cached by kernel (unless opened with O_DIRECT flag).

In FreeBSD (and presumably other UNIX implementations) they aren't: https://docs.freebsd.org/en/books/arch-handbook/driverbasics...

So, in FreeBSD "dd if=/dev/ada0p1 of=/dev/null bs=1 count=1" will fail: disk driver will return EINVAL from read(2) because I/O size (1) is not divisible by physical sector size (usually 512). "cat" with buffer size X (which depends on the implementation) will either work or not depending on divisibility of X by physical sector size, and other random factors, like short file I/O caused by delivery of a signal.

Summary: dd(1) still has its place and author of original article is getting it wrong.
A major issue is the cache coherency. If you dont have coherency, effectively you have an architecture that just multiple distinct servers.
The solution for consumers are product/price comparison sites like gh.de and idealo.de (german). I don't know the US equivalents of those, but here they get the prices from many sellers and you can compare including shipping, filter by many spec criteria and even find the cheapest solution for a basket of items, split by seller and including shipping which I believe is a NP hard problem (knapsack or traveling salesman?).

Ask HN: Which virtual phone number service do you recommend?
For security reasons I want to add a second phone number (for Telegram, signing up for services etc.)

Which service do you recommend? I know Twilio, but they are doing way more now than just phone numbers and I am afraid they cancel my account for no reason or not enough traffic.
Still my fav way to create a linux-boot-usb and a poorman's disk-benchmark tool :)
ICE is just the negotiation that happens over a side channel, usually as part your application server (since it needs to know which clients want to talk to each other). It doesn't really make sense to have separate ICE infra.
That's odd. What options? I can’t reproduce the issue on my end.
> Pkpass appears to be an Apple defined spec that isn't owned by a neutral party like a standards organisation. Yes they've published the definition ( https://developer.apple.com/library/archive/documentation/Us... ) but why would other companies embrace a definition and then entrench that when Apple could change it at any time or lock them out of future revisions?

That's overly paranoid, and the defensiveness leads to self-defeat.

There's no incentive for Apple to change the spec confrontationally like that, especially if more people use it. People will stop buying or using their products.

From my perspective, no-one's using this ticketing spec any more because of this fear. You have to download apps for all the services you want and view your tickets/passes/cards in those apps. Very view companies export just the card/ticket without an app (when some of them started out doing this), and increasingly they just keep the ticket in their app. The only thing that seems to consistently work for more than a couple of years are my bank cards - presumably because I can pay with contactless.

Those services which have given up using Wallet are now harder to use and less appealing. They create friction and dissatisfaction with every transaction. And now I don't trust Apple Wallet any more (in terms of being useful). I actually feel freer to leave the Apple ecosystem now than I ever have done because nothing works as well as promised. (The two things keeping me with Apple are not Apple benefits, but Google's failings: surveillance based business model and that their ecosystem looks worse still).
That sounds more like a red herring, food is not a service, it's a product.

Administration bloat is a problem everywhere, however I don't think that is the reason for or against national Healthcare.
At least in California, just touching holster is considered brandishing. Not sure it's the same in Texas though.
No i'm not sure, that's just what i understood from reading the article, which only mentions race conditions and something looking like a deadlock. You think it could be a deadlock in the memory allocator ?
I wouldn't mind to have that option. Issue is that in sake of optimization, there are hardly any options in majority of categories. Even 1/3 of small fintech startups are tied strictly to unrooted android/ iOS.
Just because my phone is rooted, I cannot use them as they don't even have browser option.

Same with supermarkets pushing card and having 1 tile (out of 10) for cash.
GPS as a technology is incredibly accurate and precise. The problem in narrow waterways is that even with the modern chartplotters of today, the fix lags behind – sometimes even twenty seconds or so. GPS is a very important aid in determining the rough position of a vessel, but the micro-scale navigation is just so much easier to do with navigational aids (buoys, lighthouses, glitters, leading marks, etc.)

> But doesn't virtually anyone have a smartphone now?

Perhaps one tool amongst the others, but they have several disadvantages

* You have to hold them -> one hand less available to anything useful

* Even if you can figure out a way to mount a phone so that you can read it (remember to somehow accommodate charging!), the screen is still quite small -> can't be viewed at a distance

Even if you somehow get all of the physical problems sorted, software problems still persist:

* Where are you going to get your charts from? Certainly do not expect to not have to pay for them (a couple of hundred of dollars is not uncommon)

* How are you going to view them? The solutions of the big players are quite expensive (couple hundred quid per season). Sure, the play store and such are full of some random dude's chart viewers, but are you going to trust that some random ass guy got the projection and datum conversions right? Even if they mostly did, even an error of ten meters or so could be critical.

tl;dr: a good phone-based solution costs at least as much as a basic chartplotter. In addition, you have to make multiple compromises.
It is important to carefully look into the functional context where that abstraction is used.

If you are looking for example into System Integration, Data Integration, ETL and so on, not using a canonical format from the beginning, will get you into the type of almost exponential grow in mappings between sources and targets.

The size is not the same though. Not really comparable. You can have cheaper apartments for same sq in US outside of middle of the main cities which are bloated due to speculation and cheap mortgage.
This is totally awesome and hopefully "mainstream debuggers" will learn from this.

Here's another example how memory visualization is useful, this time in an 8-bit home computer emulator (where such things are very trivial to do in realtime, because the performance difference between an 80's home computer and a modern machine is so big).

You can see how a visual effect in a scene demo works by looking at the memory access "heat map":

https://twitter.com/FlohOfWoe/status/1075083521193062401

I also found the "execution heatmap" very useful for debugging, this just "paints the map" where the instruction pointer is reading memory, with the current location extra highlighted. One can understand a lot of things about a given program by just watching execution jump around in memory (such as, where are the "hot loops" versus what is one-time code, what memory regions are code, and what are data, etc...

There are digital presses in B2 size using dry toner indirect (“laser”), liquid toner indirect (also “laser”), and inkjet processes. They are available in both sheet-fed and web-fed (“rolls”) configuration. (B2 sheet is 514x728mm, ~20x29”, or think “home/small poster size”; it’s sometimes called “half sheet”)

I work in this space (as a consumer of this equipment); all opinions here are my own, not my employer’s. For that reason, I’m reluctant to link to any specific vendor products, but if you’re interested, googling/YouTubing “b2 digital press” will give you some cool “how it works” videos.
> If you have a ship that hasn't paid its docking fees, what can you do?

You can sue the owner. If they don't show up that doesn't mean that they automatically win the case - if anything, it's the opposite. If you can't identify the owner you can make the case against John Doe and still have a state appointed defender represent the owner's rights. You can get a court-ordered injunction to detain the ship until the case is resolved.

I don't see why you need to invent a new legal concept here at all - other that it makes things easier for the state to seize things when they don't need to worry about such pesky things as rights.
I didn't look into the source code, but I wonder how it handles animations when an element moves in the DOM? How does it know that if I remove and add a new element, that it is in fact the same element that has moved? Probably need to have a unique id attribute?
USA exclusive
When I'm asked "what if it changes?", I usually answer with something like "we'll solve it when, and if, it happens". I'm a fan of solving the task at hand, not more, not less. If I know for sure that we're going to add feature X in a future version, sure I'll prepare my code for its addition in advance. But if I don't know for certain whether something will happen, I act as if it won't. It's fine to refactor your code as the problem it solves evolves. You can't predict future, and you'll have to be able to deal with mispredictions if you try, too.

I think this guy has the right idea but may be confused about how `git` works: every repo you `git clone` is an entire copy of the repo and all of its history, completely stand alone.

You can never lose your work as long as you retain a copy of the repo. You can never lose other people's work as long as you retain a copy of their repo. `cargo` does not require crates.io, can use other registries when they come into being, and can refer to modules by file path or by `http` uri.

However, he is trying the tact of talking about how crates.io uses GH's oauth; this is a clever thing to do since it ties explicit ownership of the repo to the user. There is nothing stopping crates.io to also use other ouaths the same way, as all of the major GH alternatives also support oauth and can be used for this purpose.

Crates.io most likely doesn't want to handle internal auth, as this becomes a maintenace nightmare for a 3? person team. Since the team is also small, adding other oauth->proof of repo onwership backends is presumably on their todo list but something they can't commit to.

Good news, though: https://github.com/rust-lang/crates.io (and they accept PRs)

“There is a basic distinction between life expectancy and life span,” says Stanford University historian Walter Scheidel, a leading scholar of ancient Roman demography. “The life span of humans – opposed to life expectancy, which is a statistical construct – hasn’t really changed much at all, as far as I can tell.

Life expectancy is an average. If you have two children, and one dies before their first birthday but the other lives to the age of 70, their average life expectancy is 35.

That’s mathematically correct – and it certainly tells us something about the circumstances in which the children were raised. But it doesn’t give us the full picture. It also becomes especially problematic when looking at eras, or in regions, where there are high levels of infant mortality. Most of human history has been blighted by poor survival rates among children, and that continues in various countries today.”

Adjust for infant mortality, war, etc., humans are still humans.
Altavista (AskJeeves, Yahoo, pick your poison) existed in a market space where there was real competition to be had. The Google of today does not.

The sad reality is that there's no incentive for Google to "fix" searches like this, and indeed it's not even their stated goal to do so anymore. They've been more focused on creating searches that take in "natural language" and provide results based on what they think you're looking for.

You insist, vociferously, that renewable energy storage infrastructure has not been built out yet. But we all knew that already.

It has already been explained to you numerous times that spending on storage would be foolish until we have enough renewables built out to charge it while also meeting demand; for now, money is much better spent on generation capacity. When it does become useful, storage will be radically cheaper to build out than now, as its cost is falling very, very fast.

The gating condition has not been met since the last time it was explained to you. Be assured, you will know when it comes about. We will not require further such reminders in the meantime.
