Speaking about C, since I never went too deep into C++.

The original assertion was:

> ...gives a developer more insight into the actual machine...

For better or worse, Rust feels like a reference is a proper abstraction over a memory location whereas C drives home that it really is just a number. Perhaps I don't know Rust well enough but, without unsafe, I'm not sure how I would refer to an arbitrary memory location or use pointer arithmetic to access memory locations relative to a known memory location in Rust. Vector indexes in Rust appear to be more than just syntax sugar for addition whereas C allows both array[2] and 2[array]. And I know that Rust will prevent me from accessing memory that's already been freed since it's one of the selling points of the language.

Now you can argue that Rust is mostly saving you from unpleasant consequences, and you'd be right. But the fact that C forces you to understand those unpleasant consequences teaches you something about the nature of the underlying machine. C makes you realize just how much of a "wild west" situation exists at that level. It would be very easy for someone to learn Rust without being confronted with that fact.

That's what 802.11ad is for, which can transmit over 60GHz (which limits it to basically one room, as it's quite readily attenuated by even air).

That said, at 60GHz of course bandwidth is awesome. TP-Link has a router:

http://www.theverge.com/2016/1/5/10721550/tp-link-talon-ad72...
Also to note is that a potential hacker doesn't need to be within the visible range of the home WiFi network with the increase in coverage.
I don't believe we really use cordless phones in the 900MHz anymore and I believe the consortiums determine which spectrums are sufficiently unused before targeting them.

Verizon and T-Mobile have some LTE spectrum in the 700MHz range for building penetration and range so I expect to see great things at the 900MHz range for lower power devices.
>Our direction of time is defined by the observation that entropy (or "chaoticness") always increases with time. If you mix orange juice with water, you will not see the result unmix itself again, even though the interactions between the individual molecules are perfectly reversible.

Perhaps in zero-g, under the effect of no acceleration and/or gravity. But I've seen all (most of) the non-water bits settle in the bottom of a bottle left alone for a long time.

That doesn't detract from your overall point about entropy, but it's probably to use an example based on the quality of energy (try to generate electricity from the heat that leeches from the walls of your cabin in winter).
When can I buy wireless headphones based on this standard? I hate the short range of 2.54 and 5 GHz headphones.
First of all, this is not "free internet" they are trying to provide.
Second point - if they were trying to genuinely provide a free internet service, nothing is stoping them from doing it without all the legalise TOS that surrounds it at the moment.
Third point - Free 200MB or 500MB data per month for each person is the best way to do it(no video streaming/big files download), if "helping" was the actual intention. If the only services that is accessible through it will be the ones approved by facebook, stop calling it "free internet".

Also the cost of providing the service is on the ISP/carrier that FB ties up with.

The key factor that is glossed over is:

> Though the programme is promoted by Facebook, its costs are borne by the mobile-telecoms operators.

I was all for facebook basics when I thought Facebook was paying for poor people to access at least some restricted internet access. But its actually the operators that are paying for this. Giving away free access to some sites in a walled garden, hoping those same users will pay to access other sites at some points.

So Facebook is just a beneficiary in all of this. Getting new users at no cost. Taking the credit for it, while operators are actually paying the bills.

Ask HN: Curved Monitor for Designers?
I'm contemplating spending good cash on a large curved monitor as opposed to 2 flat ones.

Is it Rad or Fad - and any observations from UI designers / artists / matte painters?

What about devs? Obviously rotating the screen vertically is, uh, interesting. Any one code on large curved monitors? I'm guessing it's fine since it's IPS.

cheers!
Both Boltzmann's idea of fluctuation and Feynman's argument against it are unfortunately devoid of meaning, because we do not know how highly organized and thermal death universe look like. We never saw and probably never will see another state of the universe and there is no way to experiment with it.
Or you could just look at the amount of bandwidth transferred during that connection is using and if it goes >5MB, start throttling.

Well, I remember a time when it "felt" like everyone with an ounce of ambition, a computer, and the most rudimentary know-how should feel entitled to spin up something with an impact.

I don't know if that was every really the case. But it's clear that it's certainly not the case now.

Also, the Internet (remember when you used to capitalize it?) is not the end-all of technology. And when it came out, most folks didn't realize how powerful it would be until much after. So what's next? Maybe we just have to try harder to define our own success - find something you care about contributing to. It's not "disruption" in the way it's portrayed in the tech-tabloids, but in the end it's about how you choose to spend your time and energy before you die.
Why not call it a "POC" (proof of concept) round, or "concept round", or "dice round"?
60GHz also limits you to direct line of sight. 60GHz propagates similar to a spotlight.
Your hypothetical isn't useful; you'll have to give a probabilities instead of certainties.

"created by observation of cyclical systems". Can you elaborate on that? I'm not sure what you mean, but it sounds interesting. It seems to me we believe time "exists" because of causality; things that happen at "this moment" affect things that happen "in the future" but not things that happen "in the past". We've also predicted and measured certain weird things about time, such as how it can go faster or slower.
At that router - LOL. "7gbps wireless throughput". Great. "1gbps ethernet port"... err?

Assuming your device can support 802.11ad, too, of course.
They say 900MHz but that's really just a rough ballpark, presumably it will use the 915MHz ISM band in America and 868MHz in Europe.
> Also the last time I saw a video about a low level language discussion, only Rust had a dev there nobody really knows. C++, D and Go had prominent people speaking for them.

They were each represented by a prominent member of their language design team. Its tragic that more people don't know of Niko Matsakis, but his blog is one of the best resources on the design of the Rust language: http://smallcultfollowing.com/babysteps/
Great, but it's not clear how this is different from several other Python packagers like Pyinstaller.
Any clues?
That's already the case with directional antennas.

"That much nuclear material" as in "enough to visit nearby star systems". Perhaps you've underestimated the literally astronomical distances involved, and how much power is required to get there in anything close to a reasonable time-frame. It would be required to accelerate at full speed for centuries, then turn around and decelerate for centuries more. It's easy to imagine that taking enough nuclear material to be able to cause a non-negligible nuclear disaster on a scale that meets or exceeds past nuclear disasters. Fukushima and Chernobyl weren't exactly trying to travel to another star system, after all.

Then again I might be completely wrong, but seeing as it's literally rocket science, I think you can forgive my ignorance and I can forgive your condescending tone.
The cryptography in this system does not appear to be safe. Apart from the fact that it's browser Javascript, which can only be as secure as the server's verified TLS key anyways (and thus doesn't add any security TLS doesn't), it's also using outdated RSA crypto constructions that are vulnerable to attacks.

I think you should find an expert to work on this project with you and provide the cryptographic design for you. Cryptography in a social network is like cryptography in a messaging application: it has to work. It's irresponsible to offer someone a solution for sharing secrets (with peers or with their network of close friends) if you can't keep those secrets.

Thankfully, you're not doing that yet; I think it was good judgement for you to include the "NOT SECURE" warning in the Readme.

Good luck!
Hopefully nowhere and never. These are bands unsuitable for high bandwidth applications and we certainly don't need more of the public spectrum polluted by things like cheap chinese RF headphones.

Thats actually OK. Advertised wifi speeds usually manage 20% of that in real life so sounds about right.
When you help people you should make it clear to them that they need to meet you half-way. If they ask for your help, it should be obvious that if they aren't willing to meet you half way then you aren't responsible for them and are probably hurting them by trying to help.
>If you mix oil and water, you will see the result does unmix itself again. Does this mean entropy decreased and time direction got reversed? Nah.

Moving an object to higher gravitational potential decreases the entropy of the system (and thus requires work, unsurprisingly).

Mixing oil into water means you displace some volume of water which were closer to Earth with oil bubbles (which are lighter than equivalent volume of water) while you force the displaced water volume higher/further from Earth. Thus by mixing lighter oil with heavier water you decrease the entropy of the gravitational system consisting of the oil, water and Earth. Left to its own devices, the system evolves along the entropy increasing gradient - heavy water goes down displacing lighter oil up, thus decreasing the gravitational potential of the system (the friction during that "unmixing" is the work of the gravitational force that ultimately results in the heat that is lost away into the environment).
Interesting study, but the article is incorrect when it says it has "proven effective at treating tenacious gut infections". If you click on the link you'll see it is an open-label trial. Results from placebo controlled trials weren't quite so good:

> interacting with the hardware is easy, speaking to a web API becomes a huge pain.

Particle (particle.io) does a pretty nice job of bridging this gap in my experience. You still write code in C-like Wiring, but they have built-in APIs for storing data in the cloud and calling webhooks. It's not as simple as interacting with web apis from JS, and the fact that it relies on their cloud service would make me hesitate to use it in a commercial product. But for my home play projects, it provides a really nice balance of using C for the hardware stuff without making the networking stuff a major pain.

In California:

CVC 21654:

(a) Notwithstanding the prima facie speed limits, any
vehicle proceeding upon a highway at a speed less than the normal
speed of traffic moving in the same direction at such time shall be
driven in the right-hand lane for traffic or as close as practicable
to the right-hand edge or curb, except when overtaking and passing
another vehicle proceeding in the same direction or when preparing
for a left turn at an intersection or into a private road or
driveway.

(b) If a vehicle is being driven at a speed less than the normal
speed of traffic moving in the same direction at such time, and is
not being driven in the right-hand lane for traffic or as close as
practicable to the right-hand edge or curb, it shall constitute prima

> "The problem is those full clones then needed to be patched."

As would the VM's you said you ran previously. Sadly patching is one of the biggest problems in IT. Which is where tools like Puppet come into their own (which I think you did say you run?).

> "The sparse zones were not usable because then you could not install or update software in isolation. I see the same thing on the ez-jail page:

> > "Because the basejail's copy of the userland is shared by the other jails, updating the basejail automatically updates all of the other jails. Either source or binary updates can be used."

I think that's a little deceptive. You can still install packages in the containers separate from the basejail. ez-jails would be completely useless if you couldn't. basejail is essentially just the FreeBSD core (ie it excludes /usr/local).

> "So, if an update to basejail breaks something, it breaks every jail linked to it? What if I want to test my software on FreeBSD+1?"

Then you'd have that as a container without basejails inheritance. Nobody says you have to create every jail using the same templates (though you did earlier complain about having to patch everything in isolation :P)

Personally, I tend to just take a ZFS snapshot and then rollback if I ever run into issues. It's a little lazy but works well enough for planned maintenance windows.

-----

Those arguments aside you do raise some interesting points; and I hadn't heard of Triton either. So I've definitely learned something new today. I can't really say I've had the same requirements to spin up and destroy new containers with the same frequency that you have, which would explain the differences between our experiences. For what it's worth, ez-jail does have a solution to those kinds of usages via "flavours" (loosely like VMWare VM templates). However I suspect this might still fall a little short of your specific requirements.

There's a difference between wanting the keep developer salaries low and wanting to capture all the developers to deprive competitors of them.
I must admit this is the first I hear of ad standard so I'm a little concerned that by the time I've got the tech in hand my internet options are already at the next level. (I should add that its all relative - 100mbps is just fine for my needs to be honest & will be for a long time)

Its a touch ironic. In my previous country it was the opposite way round - nobody could imagine a situation where the internet link could saturate the wifi. No I've got the opposite problem...
60GHz (which limits it to basically one room, as it's quite readily attenuated by even air).

Living in a condo tower where I can see -- and have my network interfered with by -- 70 other wifi networks, I consider this to be a feature rather than a disadvantage.
Are there wifi-based headphones for any standard? Seems like a terribly complicated approach.
Precisely. I worked for a water utility, in Australia, and this was the issue.

"What's in waste water?" People would answer, "E coli, food scraps, garbage".

Okay, so here's tap water. Show them lab samples.

Do the same with our 'grey water' (after processing). Lower impurities.

People still wouldn't touch it. We could use it for things like golf courses, etc, which lessened the load, to be sure. But still.
200 people a year die from nuts and peanuts in the US, therefore eating nuts and bringing them to social situations is "quantifiably [risky] (to themselves, others, and the claims department) behavior."

There is a subtlety here in correlation and causation.

>I'm sure there's people out there that drive like maniacs 90%+ of the time and haven't had an accident, but that doesn't mean they aren't significantly more likely to do so in the future.

It's not 'they', it's 'their cohort', and the apparent risk can be very sensitive to the level of detail and factors accounted for - such as nut allergies.

As long as we know the ruler IS bent - because we need some way to charge people appropriately for insurance.
I wonder if its too late though, perhaps the licensing is easier than Zigbee?
Transferring a domain costs money (although not much); more importantly, it causes the domain to be renewed for an extra year. If the owner of the trademark doesn't want the domain to exist (e.g, if it's some off-brand use of their mark), having the domain transferred to them is counterproductive.
I know that Goodyear was resistant to tags for many years - they cost too much. Margin on tires is razor thin.
At 60GHz it's almost more appropriate to compare to a laser pointer. The wall will probably be a problem.

Think of the role that an "Advance Man" played for traveling circuses in days gone by...they were on the road keeping a couple of towns ahead of the circus' itinerary and drummed up interest with posters, flyers, and sales puffing, so that the circus would be profitable once it arrived...

Spending VC money on "advertising", or attempting to generate the same "buzz" for free on social media probably amounts to about the same thing...

Is the "circus" (startup) being advertised to investors the "real deal"...ah, the risk of the bet...will it scale, or will it fail...?

It seems that the savvy are becoming a bit wary of relying on the hype of an Advance Man (advertising)...when marketing is required to establish a product as opposed to the product establishing itself, through proven utility, the ground is certainly shaky...
Thanks btw. I use your library and love it.

I recently bought an 802.11ac wifi adapter promising a nice theoretical 600Mbs in the 5Ghz band and all I was able to get from it was a practical 65-70Mbs (at 2 meters from an 802.11ac router) using the best drivers under Windows. Under Linux the (5Ghz)AC mode didn't work (buggy driver; no vendor support) so I was back in 802.11n mode. Quite underwhelming after spending 200 euros on router and adapter. I will definitely not "early adopt" wifi 802.11ah whenever it appears..

How much they (NRA-ILA) spend on lobbying is transparent, duly reported like any other interest group.

ILA is just one facet of what the NRA does; the rest is generally ignored by major media.

(ILA = Institute for Legislative Action, the lobbying arm)

BTW, I'm not saying that the rest of NRA isn't also financially transparent, I just haven't researched that in years.
Bullshit, your device is at fault and not the protocol. I bought a 802.11ac dongle with external 10dbi gain antennas and have been enjoying extreme speeds and connection strenght throughout the house, not to mention to the routers of 30 of my neighbours.. And that's only 5GHz. For comparison, at my desk three walls away I used to get about 40-50nW signal level off my built-in adapter and antenna in my Lenovo laptop. With the new setup - 60mW... The router sends at 100mW. We're talking pushing 90MB/s+ constantly no matter where in the house with absolutely no connection drops.
I love that this comes with an apt-get line telling you exactly what you need to install to get running. Every project should do this.
