Just as the gravitational attraction of large gas clouds isn't typically enough to bring them together in intergalactic space gravitational repulsion wouldn't be enough to keep them apart. Instead, ordinary kinetic gas dynamics is what governs a lot of their behavior. Which means that the intergalactic gas clouds from a matter galaxy cluster would definitely end up intermingling with other intergalactic gas clouds from a nearby anti-matter galaxy cluster. And when that happens, the electrostratic attraction of oppositely charged particles would result in a high rate of annihilations, enough to shine brighter than even many billions of stars.

Also, it wouldn't matter if the gravitational attraction between matter and anti-matter were negative, that would mean that instead of being pulled toward the most massive nearby collection of matter an anti-matter galaxy (or cluster) would be repulsed. But that would simply drive the anti-matter galaxy into another region filled with matter galaxies, just at a lower density. Your theory really only works if there are enormous divisions between matter and anti-matter sections across the entire visible Universe, which there's no evidence of whatsoever. Even an anti-matter galaxy hiding in a massive intergalactic void doesn't help much because even such voids are filled with low density gas and dust clouds.
Many garages have such a timber across the top of the door (you can't see it under the siding and paint). Those things are expensive.
It's not a larger population, it's a larger population of people who can afford to be idle. (Or at least, not spend all of their time working on their day-to-day survival.)

It doesn't matter how smart he is, if Einstein grew up to be a subsistence farmer, in a society with low social mobility, he'd die as one.

I do not see why extremely pure water would leach metals any more than tapwater would. Chemically it should not matter. All species will reach equilibrium between the surface of the container and the liquid and if dilute they will not care about one another. That equilibrium will be reached faster if the temperature is higher.

What is true is that you should not drink hot water from pipes because hot water does leach metals, tapwater or otherwise.
I'm a pretty heavy RESTful API user (feels like what I spend most of my day doing a lot of times), a pretty heavy Paw user and pretty well versed with its feature set, and on the CLI side, curl | jq. So I think I can actually probably answer this pretty well.

Paw helps me compose arbitrary calls faster. It also helps me just keep track of and search API calls really easily, just by searching the request list. I have an API call right there, with the JSON body, and I don't have to pull up the API docs. It's just way better than having a bunch of little shell scripts for these API calls, and better than having a big, ugly, stupid text file full of API calls, because I can execute them, and it really helps in composing them.

It just helps with a lot of little random stuff. Like, if you tell it you're doing a JSON-body form post, and you've got quote marks in there, it'll get those quotes escaped right to get it embedded in the JSON.

If you're a heavy RESTful API user, I'd say just give it a try for a month and see if you feel like it's worth it. I thought it was.

There's command history, and if you're executing calls multiple times in a row and might want to see what changed between them later, the history is great. You can scroll back in your terminal, sure, but you tend to close terminal windows and lose the output. It just keeps everything glued together, it's really much more coherent than trying to throw around a lot of disparate API calls in a terminal with curl (or httpie.)

That being said, I do find it to be complementary to curl | jq. For one, the "keypath" filter in the http exchange pane of Paw doesn't take anything close to a full jq-like syntax. I pretty frequently use the "curl" code generator (it's got an httpie code generator as well, but it doesn't seem that one is as good at shell-quoting edge cases. Not sure who maintains that extension and if it's open-source, but if you love it, you might be able to help fix it if it interferes with your workflow) to copy out the call I composed, and even executed in Paw, so that I can do some jq mangling. (Or i could just copy out the json body if I didn't want to re-execute the call.)

If slinging RESTful API calls is a significant part of your day, you're almost certainly going to find value in something like Paw. It's got a 1 month free trial. I tried it, and didn't really plan to buy it, but a month ended, and I was using it and liked it.
That makes setup super easy! :)
Bug Bounty 5 years in
Thanks but I only wanted to point out that there is a real dichotomy between an implementation and its proof of correctness, even up to isomorphism. But I maybe misunderstood what was being discussed!
Ask, but don't expect a very honest answer. Check them out on Glassdoor.
Sweet the spreads are reduced. Thanks HFT! I've been up all night worrying about them.

Everyone profiting from HFT are trying desperately to convince everyone else that they provide a service and benefit and they just can't understand why normal folks aren't buying it.

The amount of power of HFT to move markets is frightening. Like, for example bogus assassination tweet sending the stock markets plunging $136 billion in two minutes*

Well yes, provided those smart people have the opportunity to pursue their intellect.

If the vast majority of the people are serfs barely scraping by, and the only people with "idle time" are inbred dunces hanging out at various courts, progress will be very slow (see Europe during the dark ages..).
The browser has always been the one of the easiest ways of tinkering with programming, but these days our browsers come with sophisticated developer tools unlike anything else installed on an average person's PC.

Back when I didn't know anything about compilers I wanted to write 'C++' but didn't understand how I could produce an executable, I instead saved html and js into folder and loaded them up in the browser -- and any changes were visible on refresh.

And actually, these days this tinkering doesn't even have to take place locally. With sites like jsfiddle, anyone can develop remotely while still being able to debug the execution from the browser.
As someone who just spent 30 minutes setting Paw up for my needs, here is my review. Unfortunately, it is not worth $50. It's not the price point itself, it's the fact that the app is too unpolished to pay any amount. After the first 30 minutes, I won't be continuing - and would not even if it were free.

The application hijacks mouse events for custom widgets that don't function as expected. It takes far too much pointer precision to manage the request list and the groups. Half the time the drag-and-drop glitches so that you are highlighting rows without actually having the item with the cursor. You also cannot drop a group to the end of the list. Similar problem in the environments config window: add a second environment for a variable; the column widths are too short to see the variable's value, so you try to resize the columns and it doesn't work even though the resize icon appears on hover.

The "JSON" response format is hideous and for some reason the default. The "JSON Text" format is what I want and switch to, but this fact is not remembered and every single new response resets back to the ugly xml-tree-like format.

By the way, trying to click the help icon for dynamic values opens the documentation to a page[1] that doesn't load due to an encoded '#' symbol (%23). Again, a sign of a final product with very little QA, being sold at a fairly premium price for which one expects quality.

The UI and interactions are far from seamless. The constant harassment of a popup trying to get me to upgrade is the last straw. When a user is on trial, you don't interrupt their workflow every few minutes.

Working in scala and enjoying it a lot ! You have a library for every thing and syntax express functional code elegantly. The mix of object and functional programming make all seems a little bit confusing. A problem haskell doesn't have.
There was work to make nix work in Cygwin, it's been paused, but there was partial functionality. I remember one of the problems was Windows symlinks.
When prices rise, the result is that the poor have less. The poor will have less water and less food, and those that are already on the edge will dip below what they really need. "People" won't eat less meat; poor people will eat less meat. As the share of income spent on food is much higher for the poor to begin with, they will feel the worst of it. You really don't want to go back to the days when class differences manifested in basic nutrition.
In general, it's a foolish idea for regions to give up agricultural capability because the fickle nature of international politics and economics means it is next to impossible to always guarantee food supply through trade.

What if your current comparative advantage gets lost due to development elsewhere? Your exports will no longer earn you the foreign currency you require to import food (look at Venuzvela for a recent example or the disaster of Haiti where IMF prescribed food imports or India's famines of the 1960s)

This is the reason nations heavily subsidize agriculture even when they can rely purely on imports.
Yep, currently the maintainers are the ones doing resolution in order to achieve package set harmoniousness.
ml languages (sml, ocaml) support side effects through mutable references, and sequences in case you need it. Haskell aims for purity so you encode side effects as threaded state variables through functions (State and IO monad); other kind of side effects possible with this pattern too (Continuations, ...).
Maybe the destitute don't yet have the language to argue the disenfranchisement, but one day they will, and unless someone makes it (Indian) society's problem to address, it will become everyone's problem and a drain on the economy and prosperity. I can understand the new middle class wanting to enjoy their newfound comfort by themselves, but, for their own sake, they should be worried for those in their own society --they are not scoundrel invaders, after all, because if they don't it will be to their own detriment.
I have never seen a clean taxi except once, and also 80% of drivers had broken machines and took me to ATMs instead. One guy even had his own square reader, which I thought was nifty. But the best part was discovering that our new home address was blacklisted by taxis due to previous occupants shenanigans. Thank god Uber came and smashed them into the ground.

I agree, before I buy software or start using something I will search on HN for threads like this to see what criticisms others have and what alternatives other people use. Many times I will find something with the same features but cheaper or open source.

If people stopped making comments recommending alternatives, similar things, and criticisms I probably wouldn't even look at the comments. I don't know if other people use HN like this, but it's the main reason the comments on here are valuable for me.

Most systems have package managers with versions and a central repo and dependency tracking.

Problems with fetching builds are rare but if you care package managers frequently have some not exactly recommended plugin to allow vendoring.

Plus with the package manager you can update the optionally vendored dependencies quickly.

Central repos are less likely to be deleted then github repos and some like Crates.io have a policy not to remove crates(or allow authors to remove crates) unless there are legal issues.

A better solution (then vendoring) for larger organizations that is also usually available in the form of mirroring or partial mirroring of the central repository(and pulling from that instead).

"increasing the size of (pie)"

this is relatively vague as if u do read the article, there are more and more adjunct and temp faculty positions at universities, not more tenure-track positions. besides, the pie of r&d grants in term of nih or nsf budgets did not grow much in the past decade. also i dont see there is major possibility for anothe UC system or ivy league to be duplicated in the next decade or so - it takes much longer time to build an oven for a bigger pie.
The rule (betteridge's law) says more about the journalists who craft headlines, than it does about news articles ending in question marks.

99% of journalists using interrogative headlines are not being scrupulous, when they do so. This is especially true, if the question seems shocking, or even slightly surprising, in some way.

Free WordPress hosting – Launching promo
Hey Guys,

I have started a hosting company a month ago and I'm giving out $30 dollars worth of hosting for everyone registering in the next few hours.

In the most basic plan that means 3 months worth of free hosting! The basic plan is ideal for anyone with less than 20.000 unique visitors a month, but really there's no limits, we just say that so you can take the best performance out of it.

Here's the link to the website:
https://thathostingforword.press/

And here's the link to join:
https://cloud.thathostingforword.press/register

I just need to say, THERE'S NO CATCH! You go there, you register, you get the 30 dollars worth of hosting. You're gonna need to put your credit card there, but we will only charge you after the 30 dollars have ended. If you opt out before the 30 dollars (AND YOU CAN DO IT AT ANY TIME), we won't charge you at all.

For any people suspicious: I'm doing this as a test, I wanna test the servers and I want to hear people's feedback about the service. It's a new service, it's a new way of doing things so I'm looking to collect feedback.

ALL RIGHT, GOGOGOGOGO, as I'll have to end the promo after a certain amount of people (I'll post it here when it's over):

I've said this for years here in Australia, when people talk about a "water shortage" - there's no such thing. What there is, here at least, is a cheap power shortage and a water infrastructure shortage.

Yup, it is exactly that.
I agree with the general sentiment that we shouldn't hound on this thing for not being very accurate - professionals are using professional equipment, and this is more likely aimed at preppers.

I am surprised to see that they list the operating temperature from 10 to 40c - I wonder why it stops working outside those bounds or how off those bounds are. It would love to see someone to order a few of these and review them in all sorts of different tests.
Hmm this made me wonder: what would happen if you made a system that supported multiple architectures (ARC, PPC, x86, FPGA, ...) at the same time ?
Not equivalent but comparable in certain ways. The claim I am responding to is that the entire concept of "expertise" is equivalent to a dictatorship.

More than one taxi is clean. Fewer than 80% of taxi card readers are broken. No one will believe your claim of being blacklisted unless you give proof, and taxi services have hardly been "smashed into the ground" by Uber. I continue to enjoy using taxis in every urban area I travel to, and look forward to the way taxis keep competition pressure high for Uber by adopting various changes to make their level of service indistinguishable in the new ways that customers have enjoyed using Uber.
one or two publications without repeatable results might be acceptable - maybe he or she is just out of luck or some how choose the wrong hypothesis. but if there are five or six non-repeatable papers in the publication laundry list, esp some used for degrees, promotions to tenured positions, or grant applications, this makes him or her looks like fraud with a track record of publishing "personal opinions."

Checking food with a gamma radiation detector is not too useful. [1][2] Some "preppers" are into this, and get excited if they count for an hour and get 20% higher than usual. They're probably seeing ordinary variation in background radiation, which varies over the course of a day.

A tester called LANFOS has been developed in Japan, to deal with possibly-contaminated food from Fukishima. It's a round pot-like device with shielding and plastic scintillation detectors into which a sample can be inserted. This has been tested against other methods and the results agree with standard laboratory tests.[3] That's a practical solution in an area where you really do have to test.

If you're worried about suddenly encountering a big gamma emitter or X-ray beam, get one of these.[4]

Just to kind of mirror what the poster you're replying to said, it is "unlikely" you could use this to accurately detect radon. This article[0] talks about some of the difficulties you may face and how much data you'd need to collect.

Considering how inexpensive and reliable radon test kits are, it may be advisable to stick to that.

Always nice to learn new things about your own country :] Though I'm kinda surprised by point 2 (people dying at home) and 4 (road workers dying). I saw 2 in the past (like 20 years ago or so) in the news but does it realy still happen every single year? And I don't recall ever hearing about 4: might be me (I don't read news on a regular basis) or does it not happen often or with only minor injuries or is it deliberatly kept out of the national news?
GIMP is an icon of open-source software, but do any professional designers use it full-time over Photoshop?

For what it's worth, I've been using this app for over a year and I haven't been noticing the issues you're talking about. My request list probably contains hundreds of requests from different projects grouped into folders.

I've tried using postman but it just isn't the same. Paw is much more efficient with screen space, and I love being able to copy any request from Chrome directly into paw and being able to tinker with it right away.
Fresh water is very easy to store for prolonged amounts of time, that makes it easier to run a desal plant on intermittent (solar/wind) power than many other high-energy industries.

(However, in practice the capital costs of a plant are such that it usually makes sense to use non-renewable power to let them run 24/7 instead of having them idle when there is no renewable power)
If the amount of computation that can be done is finite, then subjective time is also finite. (And vice-versa if the amount of computation is infinite.)

What does infinite time mean in a universe where nothing happens?

I hope I live to see a grand unified theory of physics which explains how space-time emerges from the quantum scale, but also how consciousness emerges from computation. Maybe in the future, when these theories are developed, we can have infinite consciousness, infinite subjective time.

I also acknowledge that I may be confused entirely and the previous paragraph has no meaning.
Unfortunately the idea that a new language meant for widespread use can ship without its own package management systems is even more broken.

Generally languages need a good tool to allow (nested) dependencies that has a simple (preferably declarative) dependency file.

Would it be nice to be able to have a cross language platform tool(jvm tools do generally play nice across languages in my understanding) like nix that also allows setting up other non language specific dependencies? Yes. But I'm not sure any are good enough/simple enough yet. Also language ecosystems tend to avoid non language dependencies (unless they're so common theyre typically installed with the language like lxml/libxml2) or have crappy ways to try to build c dependencies. So this is if not solved partially worked around.

These package managers are mostly for development, not deployment although frequently they are also used to build or even deploy code.

It would be nice for each language package manager to have plugins to generate self contained deb/rpm/ect. for deployment or even fancier to allow some dependencies to be (assuming it's not a language that prefers static linking/bundling) satisfied by system packages. But these take time and effort to write.
Love it. Been using for a while now.
