The efficiency gained by stepping up AC to higher voltage (and correspondingly lower current) is far greater than that lost to skin effect. Since there is no way to efficiently step up DC (modern DC-DC converters are still horribly lossy), AC transmission ends up being more efficient, by a long shot.
We are using RocksDB as well for something. Although based on LevelDB, but its pretty different now. So can be added as a separate entry.

Trivium: a friend on G+ shared with me a story about having a Geniac kit as a kid -- an educational "computer" sold from 1955 through the 1960s by Edmund Berkeley. Included with was a copy of Claude Shannon's "A Symbolic Analysis of Relay and Switching Circuits".

For a kid's game.

Contrast that with today's "deep analysis" articles in which VirtualBox VMs are referred to as "Russian dolls" (to reference an earlier comment of mine).

Am I the only one deeply disappointed by SNI? Having the domain going out over plaintext is a major step down in privacy from the way it was before.

(Yes, there's an additional leak in the form of a DNS lookup that has to happen, but as a client that's usually easy to address if you care.)
If that helps them be less reliant on Google, I'm not too upset about it, as long as they leave the option for not being tracked by those ads, and they aren't too annoying. Also, we've learned NSA takes advantage of ad networks to inject malicious code into people's PCs, so I hope they would try to make them as safe as possible against that (only encrypted ad networks?)

I have plenty of people I believe in. In the sense that almost whatever they say, I'd think really really hard before disagreeing. Even then, if I find them unconvincing, I'll eventually disagree.

I personally don't hold Rob to be such a figure. I believe he's quite ignorant when it comes to many important topics in computer science (e.g: he made some comments that make it clear he does not understand parametric polymorphism). I find his work on Go to be a minor variant of Algol69 (and not necessarily an improvement, at that!), throwing away 40 years of real improvements in PLT.
From my limited experience, once you are aware you are in a nightmare it relieves you somewhat, and then you try to reverse/ward off the 'bad things' in various ways or wake yourself up, depending on how much control/lucidity you got.

So it's still stressful but not nearly as much as a full-blown nightmare with no insight whatsoever.

The future of domain names
About five years ago, when browsers added url search, I noticed something weird in my web statistics. I started to get a ton of traffic from Google. Soon I realized that instead of typing myhomepage.com many people just typed "myhomepage" and google would redirect them.

Today, anyone barely types the domain name ... If you want to go to facebook you just type Fa... and Facebook comes up.

So what is the need of domain names more then search engine optimizations?

The British critic probably was thinking in pounds, shillings and pence, not USD. Therefore, that $1600, at exchange rates of 1960 was £560.

Divide by two, how does £280 compare to salaries of 1960?

http://hansard.millbanksystems.com/written_answers/1960/nov/...

Manual workers were paid ~£14 a week which is £700 a year. Clerical workers in the governments employ get just shy of £800 a year.

Your musician is earning approximately a third of your manual labourer.

Let's put that into modern day money, where £25K is the rate for a person that shuffles paper across a desk for some government. Would some musician really be earning all of ~£8.5K a year for their role in an orchestra?

The answer is probably yes!!!
Well, that's a viable commentary on a possible communication channel. Much more than what I was expecting. But the one thing that it does not do is store bandwidth, that's a bad title.

It does store "bandwidth" specifically of the quantum channel, and only because there is no information going through it.

Anyway, the idea of storing qbits is quite interesting, but I don't think even that would make quantum cryptography useful.
I'd love for the possibility to start paying for stuff again. Adds bore me.
I wonder how much one would reasonably have to pay to make adds go away completely from Google and friends.

It would also be in their interest to have customers pay a base fee as then It would be much easier for them to sell extended services like music, movies and privacy.

or, at the very least, avoid making deprecating comments about those who know more than yourself?

Can someone explain the point of having EXPORT_SYMBOL_GPL() and EXPORT_SYMBOL()? Is it trying to protect the user from accidentally violating the GPL?

If I were designing that system that's what I would have done.

I can't think of an actual need for that ability, only the fact it could be used for novelty, abused to annoy people, or just flat out cause problems (i.e. what if my ringback tone is a busy signal?)
There are scenarios where HVDC can be more suitable than AC, in particular, very long distance links (e.g. to a remote hydraulic station). All of the substation equipment is much more expensive in HVDC but the benefit of eliminating line reactance can outweigh this if you're doing 1000+ km without any interconnections.

Also, interconnection between neighbouring AC grids is an important HVDC application since we don't have to worry about transient stability.

Neither AC or DC are superior. Different technologies for different applications.

You can't get a website from them, but Square + iPad is a pretty popular POS setup for local joints in my area (food trucks, non-franchise restaurants, carts, etc). For a website + online orders, you might check out Wordpress, there are a lot of high-quality restaurant themes; there's also the WPPizza[1] plugin which looks promising. If you need something more flexible and are willing to build, I'd recommend using Stripe[2] to process orders through your website (they also support coupons[3]).

Finally, if all that sounds like too much work, I'm a designer and developer and I'd love to set up a chat and see what I could do for you[4].

Hope this helps!

[4] hello at duncanmsmith.com
As I've explained on an earlier piece: the value of online discussions is the dissemination of that information. Not just to others, but to both those asking and answering questions.

From very early in my online experience, I've found the two best ways to learn things are to answer questions, and to ask them. In that order.

By asking a question, you hear from others. By answering questions you're submitting a testable hypothesis and baseline which others can respond to, and which ultimately can only be improved upon. If I'm right, then others may either respond with less-correct solutions or misinterpretations of my comments. If I'm wrong (or not as correct as I might be), others can improve on my response.

And that's highly useful.

By restricting the availability of the responses to Quora questions, you're hurting that dynamic. And there are plenty of places (reddit, StackExchange, Wikipedia, HN, MediaFilter) in which those questions can be asked, answered, and extended.

I'll draw particular attention to MF: it's a pay-to-play system for responders. If you want an account, you've got to pay a $5 fee. Which is among the reasons I don't participate (at least not under this identity -- I've generally tried to maintain an isolation of this from my real-life ID), though if I found the site sufficiently useful I wouldn't object in principle. However I don't need to pay that fee to view the responses, and I'm more than free to refer to MF posts and extend answers on other sites.

Quora does not (readily) allow for this.

Add that they gratuitously block The Internet Archive and I'm done with them entirely.
And salespeople.
"People can waste your time through any media."

That's true, but it's much easier to cut your losses with an e-mail than with a face to face conversation. If, after reading the first couple of sentences of an e-mail, you decide that the sender is an idiot and reading his message is a waste of time, you can just hit delete (or reply, "Sorry, not interested") and move on to the next thing. However, if you've agreed to meet with somebody, and thirty seconds into the meeting you've come to the same conclusion, most people would be too polite to ruthlessly tell the person to their face that the meeting is pointless, and then get up and leave. (Also, if the meeting is not in your own office, you'll have expended time just to get there.) This is even true of a phone call: most people are too polite to hang up on someone, except maybe a telemarketer.

If someone wants me to make time to meet with them in person, they should be able to clearly express the purpose of the meeting in a few lines of text beforehand.
Tom Wheeler is 66. Before becoming FCC chairman, he was managing director at a VC fund that funded early stage companies. He has also founded several companies. He was also on the board of directors of EarthLink, which is a competitive ISP with interests adverse to the entrenched cable companies. Aside from a stint at NCTA in the 80's, long before they were in the IsP business, his business background is far more skewed in favor of Internet companies.
Yes. The criteria for avoiding SNI is one IP per cert, not necessarily one IP per domain. If you can consolidate subdomains under one cert, you only need one IP. The issue that SNI deals with is with cert switching on a single ip:port... not anything inherently related to multiple domains on an IP.
> But why? I understand the rationale for websites that are political or educational non-profits. They need the public to protect them.

By the way, to what extent? Here's a hypothetical to imagine: there's a next-generation Wikipedia which is all video-based, and is, say, responsible for 100x the bandwidth usage of Netflix. Does it still need to be protected?

Secondly, why does it need to be protected? Non-profits still have to pay for the buildings they buy, the equipment they buy, etc., why should they be treated as being special in the internet space? Why shouldn't they pay more just like Netflix, if they're eating just as much resources as Netflix (or more)?
I see no inconsistency. Few people in the 1950s would have purchased such a game, despite its novelty.

Yes. It's deliberately gimped because the author of the function decided Freedom™ is more important than functionality and so they hid it behind a license check.

Go-to-Market Strategy
Because The Internet is not primarily a commercial platform, it is primarily a communications platform.

One absolutely magical aspect of the internet as it is today, is that I can stand up a server - on my desktop, on a VM in the cloud, on a physical server, wherever - and my friends can access it from all over the world.
Poor indian farmers with smartphones can use my server to get data about the local market for rubber, rich financiers can use my server to educate themselves about the likely effect of new financial laws, Strip Club workers can access my server and learn about new health risks.

All of that goes away once I need to pay Comcast a bribe to persuade them to provide access to my server for their customers.

This has nothing to do with whatever commercial opportunities the Internet may or may not provide for Big Business, and I really dont care much about those.

In time my little server may start to make a profit, maybe that is my motivation when I begin or maybe not, but regardless of my original motivations The Internet is magical technology that lets people from all over the world communicate.

that is the functionality I care about, and that is the functionality that anti-Net Neutrality laws massively threaten.
Scored as an "Artistic Thinker", but there are no artistic endeavors listed! Here's a quote from the synopsis of my test: "You might enjoy coming up with original music lyrics - or with new mathematical theories." However there aren't any musical or mathematical kind of jobs listed - half of them have to do with psychology/psychiatry and another quarter have to deal with tutoring/therapy. About the closest thing to what I actually do for a living, software engineering, is Industrial Engineer - listed at the very bottom. I think you need a little more diversity in the career choices you pull especially for something qualitative like "artistic thinker."

We were invited for an interview a few weeks ago. We didn't get in; the feedback we received was that we should get 10 customers, and reapply in the future.

I was always under the impression that YC was an accelerator that funds ideas. We were further along, had a website up with a handful of beta testers and hundreds of early signups. It wasn't enough apparently.

My hypothesis is that it makes sense from YC's perspective to be more selective, and pick companies that are more established. They are in a position to do this, given the ever-increasing number of applicants.. alas, the rationale of every investor is to pick companies that will have the highest expected returns..

> Anything that wanted to pretend to be one of the various daemons can simply speak the dbus protocol.

The internal DBus API that these components use is not stable and will not be stable for the foreseeable future; according to the systemd developers, parts of systemd cannot be re-implemented independently [1]. That effectively makes systemd a monolithic system--its components are tightly-coupled and cannot be readily swapped out.

Note that a system can be both monolithic and modular--systemd, X.org, and the Linux kernel being examples. Systemd gets a bad rap about it because the components that make up systemd were once loosely-coupled, and the need for the new coupling is unjustified.

Unless policy has changed in 5 years, you don't need to pull strings to make the police visit somebody who made tweets you don't like. You just need to make the right noises and be sufficiently offended such that the police will check whether there is a genuine problem or not.

It's pretty scary getting a phone call or visit from the police, but they make it quite clear you're not in trouble, at which point it's mostly infuriating that someone got butthurt enough to trouble you in this manner.

Please, let us get the framing of the problem right.

Netflix already pays for the bandwidth they consume.

I, as a netflix customer and a customer of Comcast, already pay for the bandwidth that I consume.

Comcast, for some reason I cannot fathom, wants the right to force Netflix to pay additional money for the bandwidth that I, as a paying customer of Comcast, consume on Comcast's network.
Very long story short, the overhead in maintaining the link state information in meshed networks swamps the available bandwidth for even modest (think 20-40) numbers of nodes. Basically, as nodes are constantly moving/coming on- and off-line, nodes have to know which nodes are in the connection graph, so they exchange that information. But that eats up all of the bandwidth amazingly quickly, leaving no room for actual traffic.

There are some other issues with meshed networks (latency, battery usage when you're just a client node, etc.), but especially for those of the kind described/dreamed about here (which are also known as MANETS -- mobile ad-hoc networks), the routing issue is a huge one.

Finally, I should note the above isn't just academic; several companies have tried to build products based on these kinds of networks -- military contractors being one of note -- and have pretty much come up short.

So until the really fundamental issues are worked out, which is in the realm of academic research, not implementation, we probably aren't going to see anything like this.
