> Not to pick on you specifically, but I've really grown to hate this type of response to this very common question.

what question? this isn't an Ask HN, and partycoder didn't ask a question.
What about all the hops your signal has to take to make the round trip? Couldn’t those be optimized or sped up? Is copper latency really equivalent to fiber?
Ask HN: Living with seriously limited Internet?
Got some family struggling with very limited Internet service in the Caribbean. Recent storms and financial challenges mean living with only mobile access at home and relying on the Wifi generosity of local businesses. Appears to make life increasingly difficult as OS updates become impossible monsters, huge page loads crawl, and gaming even on consoles won't accept entirely offline lifestyles.

Sending a few portable HDDs hasn't really helped much since so much must be downloaded directly by devices themselves. Offline installers appear to be an endangered species.

Are there other tools, ideas, or free/low cost solutions I can pass along?
> For one thing we have not been spending much money on infrastructure.

Or houses. Californians live in wooden shacks.

Or windows.

Or doors.

Or company interiors.

Or heating systems.

Or hotels (and let's not discuss motels).

(But there's many things much better about the US too)

You should try living in Western Europe and compare the small things. The difference is staggering.
"The storyline was plausible for about two minutes and then veered into a couple of off-kilter details ... then wandered into stranger and fantastical details..."

In the Dark was broadcast weekly (Saturday nights, IIRC) by KQED in San Francisco, and I had the same reaction to essentially all episodes: great production values, compelling initial narrative... then devolution into annoyingly unlikely twists, as if he had navigated a bunch of one-way streets into a dead end. And kept driving anyway. The sheer waste would anger me; I had to stop listening altogether.
the linked article (500k in one year...) is really good too.
But how do they receive the credit card payments? What company is the one that actually receives the credit card payments from the consumer? Is it the "authorized distributors"? Or is the bank account that receives the CC payment linked to the parent company? It seems that states could go after the location that actually receives the credit card payment (if it's not a Caribbean corporation).
> Unlike CarPlay, iDrive has a well-resolved, tactile and customisable physical interface.

Several manufacturers (Audi for example) offer tactile, context-sensitive clickwheel and touchpad controls for CarPlay and Android Auto. Those function as well or better than iDrive, and have the long-term advantage of Apple and Google supporting them, against which BMW can't hope to compete. (CarPlay restricting third-party apps is definitely a huge problem though.)

> Tesla doesn't support CarPlay at all, but you don't hear about hoards of people boycotting Telsa: because their system is also better than CarPlay.

Tesla's system is not better than CarPlay with tactile controls. The reason people are not boycotting Tesla is that they are overlooking the enormous issues with their interface due to superior EV technology.
Nation states only attack companies they care about. That's the point. Once you have your info on slack, you share the fate with the million other companies that nation states might care about.

Thanks. Yes. I said this very thing in my top comment. It takes a lot of users (many more than 10!) in any modern web server framework to get noticeable slowdowns, unless you've done something horribly wrong. So the question on the table -- still -- is what web applications might actually require a C++ web server, in practice?
Or just place a consumption tax at the local level - doesn’t matter where it came from.
Counterintuitively, it's actually the other way around -- at rest, more variability in your heart rate (over a roughly 20 second period) is correlated with lower levels of stress. Deep, slow, regular breathing tends to increase HRV, since heart rate is linked to respiration -- your heart beats a little faster when you inhale, a little slower when you exhale. It's desirable to have big, regular swings in heart rate, synchronized with your respiration.

Thankfully, biofeedback protocols will typically hide these details, and just calculate a single metric for you to attempt to optimize.
Honest question - Why would one want to monitor CO₂ in their office?
When ffmpeg came along nearly 20 years ago, it seemed to be the absolute video toolbox I was looking for.

It was, but you needed what seemed to be 'dark arts' to use it. And that took a long long time.

I owe years of my career to working out how to use this.
Californians live in wooden shacks.

Compare post-earthquake images from China to post-earthquake images from California, and those "shacks" look a bit better.
No, it's not advocating a conspiracy theory.

It's pointing out that you aren't very secure when you are operating in a model where it's even possible to leak all of your client records without even noticing.

Compare slack to something with actual end-to-end encryption and you'll start to see the difference.
Yes. That is what they are known for. $42K is just the upfront fee. Consider the next $10K in maintenance to be 'subscription' as well.
My first thought, seeing the title, was about Swiss banks caving to IRS/FBI over secret bank accounts. So why would anyone trust them? But then, I get that this has nothing to do with privacy.
Isn't this a pricing problem then?
Ask HN: At what point do bootstrapped/pre-seed founders need to pay themselves?
If I form a C-Corp with a co-founder, at what point do we legally have to pay ourselves?

We want to set up a corp for IP assignment while working on it part time, and are still weighing how long we want to try and bootstrap before getting outside funding.

Do we need to pay ourselves minimum wage? At what point do we need to?
I just spent 5 minutes (on my Samsung phone) trying to download the app from the link you provided. I clicked on the Chrome icon, the Android icon, and one or two others. The only one that seemed to work was the Firefox icon. But I don't use Firefox, so I gave up.
A fun read, though quite fanciful. I'll defer to posts about this on Civil War forums ( https://civilwartalk.com/threads/winston-churchill-if-lee-ha... ) where forumgoers find the idea that Lee would have ever been in a position to free the slaves somewhat ludicrous.
I was thinking it would be nice to have this insert operation pushed down into the NVM/SSD. If there could be an MMU with lookup tables attached to virtual address space regions inside the NVM, it would effectively be this.

The older I get, the more I realize that the world runs on slop. The techies are optimizing everything and removing slop, but this slop has allowed systems to be resilient. A little "waste" goes a long way.
yep, they even did some fixes for Yosemite
I know a bit of stats, can you explain why MLE is intuitive?
It’s not as hard as you think. Sales tax is mostly automated, with maybe 100 people in a large state running the program, with a few hundred more auditors.

Administration costs are not really a factor - tax people are able to statistically estimate their loss ratio and can pretty accurately model the ROI on investments in enforcement. If a state was spending 3.5% of collections on enforcement, there would literally be a guy at the door to inspect your receipt.
On the other hand, will you decide to not buy that 428 (and take your business to... whatever competitor) over $80/year?

Btw it's not like the BMW is the only one charging for the mobile connection in the car... it's basically another cell phone + monthly plan, they are not free.
In the long run, explosion in demand for GPUs will help lower prices and push the technical envelope for enveryone, including the gamers complaining in this article.
McFly's right, if a bit sensational (ehhh, it's his style.)

However, as poorly as they treat their vendors, it's nothing compared to what they do to their employees and sadly large segments of their first line and middle management not only buy into that but have spent time making that into an art form.
Constraint satisfaction is NP-complete and for optimization it’s NP-hard. In theory that means it’s going to be equally hard to determine how many steps solving the problem takes as it is to simply solve the problem.

Local search is always going to outperform global search but there’s no guarantee of a solution or an optimal one. So it really depends on your needs and how long you’re prepared to wait. Modern CSP solvers can handle impressively large problems with multiple thousands of clauses (1m+ for SAT), but it really depends on what your constraints look like.
Sorry the error seems to be on my phone. I seem to be having trouble with it right now. Including the fact that I can't delete my previous comment

True but we don't hear such atrocities committed in producing electricity. I am talking of large scale human exploitation not just the environment. Though I must admit the coal mining is heavily exploited in poorer countries.
I'm not going to argue that, but this reads like a hit piece.

I lost count of how many times this article co-mingles Meltdown (an Intel flaw) with Spectre (which affects all high-performance CPUs), and uses that confusion to imply that Spectre is an Intel problem instead of an industry problem. Then it quotes Intel making that distinction and implies that's disingenuous on the part of Intel.

Either the author doesn't understand Meltdown and Spectre or they're intentionally making misleading claims.
The Linux Programming Interface is my favorite software book of all time. I had a problem that I think a lot of other people had, where I learned C the language pretty in depth, but didn't really know what to do with it until I read this.
No surprise that this falls before the reforms brought forth by the church committee in 1975. They were presidents spanning from 1960-1976
If anything, the Pyongyang Metro is even more ideological: AFAIK, it's the only metro in the world where all stations are named after concepts (Comrade, Red Star, Glory, Complete Victory), not nearby places, although there are occasional overlaps (eg. Kaeson/Triumph is near the Arch of Triumph).

http://www.earthnutshell.com/stopping-all-stations-the-pyong...

Broadly speaking, though, virtually all older Communist-era metros were inspired by Moscow and look similar: trains, deep underground platforms, triangle network layouts, revolutionary art, etc. Newer lines are more utilitarian and there is the odd delightful exception, like Prague's weird and wonderful Line A from the 1970s:

Correction: While Nvidia is a member of the OpenCAPI Consortium and thus doing work on OpenCAPI, at present the interface between the Nvidia Teslas and POWER9 chip is NVLink 2.0.

On POWER9, both NVLink 2.0 and OpenCAPI are implemented using the same PHY. However, above that level they're completely separate protocols.

(I work on OpenCAPI drivers and firmware at IBM)
It's (unsurprisingly) pushing the used market up. I'm selling a 1070 I don't need anymore, and it's already at more than I originally paid for it, despite being over a year old at this point.

To add to this mix, I do t wear glasses but get them for a small child. First pair was at about age 1.

They are extremely handy for preventing eye injuries. Small children are pretty good at getting things in their eyes and having a pair of +9s in the way makes the eyes basically bullet proof. The cost is alarming though, US$725 approximately. While reasonably child proof, they do break and it sucks having to tell them to be more careful when they are trying to put glasses on.
this is actually worse than the source. for whatever reason, the chart appears super zoomed out for me, so the text is tiny. but even if there wasn't a font issue, the source is already clear as it is that a flowchart style diagram isn't going to help.
I am former resident of Moscow and a current resident of New York. If I could take one thing out of Moscow and bring to NYC it would be the subway. An impossible dream, but what we actually can have though is expanding our NYC subway at a rate anywhere near Moscows. Moscow added 80 stations to its subway since 2000, including 26 stations on a new circular line [0]. New York added 5 in that time [1].

Conventional wisdom such as:

// it is impossible to read past the end

x = array[i];
I wouldn't be so sure about that. Increased demand for RAM due to smartphones usage has led the prices upwards, not downwards.
I think that's only likely if the demand is sustained though another development cycle / generation of GPU products, though. If demand collapses soon, it'll just be yet another story about how the market was really weird for a bit.
I doubt that would be lower latency. Even forgetting the physics and curvature issues, you'll end up with many more hops which is going slow it down due to processing and retransmission delays.

I read the MoviePass subreddits a lot and some people have had your issue. It seems like customer service was eventually able to resolve it for people who persisted. Annoying but I don’t think it’s a scam; that connotates an unlikely intention.

And forgot to add these: https://beej.us/guide/

Beej's guides to networking and IPC are excellent.
The two points where clever heuristics can be applied are in make_choice (i.e., which variable to set such that the search space is maximally reduced) and in rewind (i.e., which variable to unset to make the problem hopefully satisfiable again).

Different heuristics work best for different workloads, so you get solvers that are specialized for a single domain.

The shortage is not entirely because of miners. Nvidia manufacturers switched to using slower RAM in some of their cards. This was actually a very smart move (they should expand it to all their cards IMO). If you want the fast RAM, you have to buy the "mining" version of the cards. So in theory, it should have no impact on the gaming market.

For some of the popular mining cards (e.g. RX 470/80), well they simply haven't been available in many places for over a year now. Their successors aren't that great for mining either because of the increased power usage and RAM "lottery" (you don't really know what type of RAM you're getting when you buy a card). But most gamers don't generally care about RAM speed. This is also why the 5 series is generally cheaper than the 4 series (where you can find them).

However, the biggest problem is that there simply isn't enough RAM. The RAM shortage is being driven by smart phone and GPU production, and suspected price fixing. Samsung said they plan on increasing production (apparently they don't like it their competitors who make inferior RAM are making similar profits), but we will probably only see the effect mid-2018.

To gather something that seems like a reasonable answer, you’d have to consider that while Earth’s magnetic field deflects charged particles from the solar wind, the atmosphere is also an important deflector and buffer for the absorption of other forms ionizing radiation, so even if the magnetic field deflects charged particles, like free protons, free electrons and alpha particles, there’s still the occasional burst of X-rays, neutrinos and the constant UV radiation and probably even some neutrons, which mostly gets caught by the air and distributed into the environment as heat.

So, the comparatively thin Martian atmosphere is probably a bigger deal than the magnetic field, generally speaking.

Anyway, to approximate how big a deal this all is, you’d have to consider the inverse square law, to account for how much weaker the intensity of the radiation is, given that Mars is farther from the sun than Earth is. If Earth is roughly one astronomical unit from the sun, Mars is about 1.52 units away. The inverse square law says that as the distance doubles, the signal strength is four times weaker, triple distance weakens strength by nine times. So, 1.52^2 is ~2.3104 times weaker intensity, which is partly a correlation to the disk of the sun being visibly smaller, farther away.

If the general, overall radiation is at least twice as weak, or more than 50% weaker on Mars, the strength of the Martian magnetic field being 98% weaker than on Earth, probably means it’d still need to be 49 times stronger than it is to effectively deflect an amount proportional to the solar wind which is deflected by Earth. This means that on the surface of Mars, 50 times the amount of solar wind still rains down into the thin atmosphere, and much of it is still probably scattered by the air as heat, instead of forming into a Martian Van Allen belt.

During solar storms, however, when solar radiation is emitted at higher levels, it could be a bigger deal. I think much of the particles falling onto Mars would simply ionize in the air overhead before reaching the surface (as static electrical effects, like lightning or aurora plasma), but flare-ups of sun weather could easily be a real problem, since they still are problems even here on Earth.

The fact that you can see a sky on Mars during the day means that the air overhead is doing some work scattering the inbound sunlight, even if the sky isn’t blue. The atmosphere is about 10 kilometers thick, and air pressure is weak enough to boil water at room temperature (less than 1% of standard good-weather air pressure on earth). So, the barely-there atmosphere ensures that skin cancer and penetrating rays aren’t a super big deal, because moreso than providing natural barriers itself, the Martian environment ensures people will pretty much always be in thick suits and behind thick windows and walls as a pervasive fact of life.
Breaking the rules with Meta Programming
If it helps; I agree with your assessment that someone could totally screw others over as long as they were sure wouldn't personally get in trouble for it. That is pretty much at the core of the argument.

I recall a case in Australia where someone mailed seniors saying 'you own shares valued at $X. I will buy them off you for half that. Please respond' and made a substantial profit from the scheme. Objectivism accepts that as a moral situation.

I can't see any elements of the No True Scotsman fallacy here however hard I look - the philosophy is that when someone is truthful and follows through with what they say they will do then they are being moral. There isn't even an objection to people being altruistic; the only objection is forced altruism.

It isn't a friendly philosophy but it is quite clear as far as moralities go. Nothing escapes from shades of grey.
Worlds first warming and cooling blanket
For anyone wondering what this is: it's tool to build flows like "git push to X". I've built a few internal tools that use this package, mostly for deployment purposes similar to Heroku (but based on Docker).

The toolkit consists of 2 pieces: the server (http/ssh based) and push receiver. The server component provides the git repository endpoint and permission handling, and the receiver piece allows to setup the logic flow, like what to do with the push and ability to read the push tree structure and run some commands against it.

I've created this package some time ago, but decided to post just now, maybe someone will find it useful.

Thanks!

Its bad. Its never been this bad before. Just go on pcpartspicker and realize that there are GTX 1080 Tis selling on third party websites for over $1500, and that's the only place you can get them beyond getting lucky.

Nvidia isn't going to ramp up production significantly because crypto could crash any day, simultaneously destroying their new sales and flooding the used market with old mining hardware. Combine it with the industry-wide RAM shortage... What a disaster.

The funny thing is, I remember back when ASICs first started coming out for Bitcoin, and a whole bunch of new cryptos came out saying "we're specifically designed to thwart ASICs so everyone can mine on the cards they have!" Well, here's what you've created. No one can afford cards anymore, and you made making more efficient hardware harder. Thanks for destroying the planet.
Exactly, it's overconfidence that gets customers, bettors, investors, etc., into real trouble.

Will recommending my own project get me hell-voted? Cixl is a straight forward 3-stage (parse/compile/eval) interpreter that is designed to be as fast as possible without compromising on simplicity, transparency and flexibility. The codebase has no external dependencies and is currently hovering around 7 kloc including tests and standard library. There are some articles explaining design decisions, but I've been mostly busy with code. The code should be perfectly readable though, and contains plenty of good ideas distilled from 32 years of daily practice.
