>>>you mean we can't prevent people from bringing an AK47 in school, as long as they don't shoot anyone?

As a matter of General Law, no.

However if the property owner, in this case the school board, chooses on their own to disallow guns on their property then a person violating that would be guilty of criminal trespass.

This is true for a Starbucks, Walmart, your personal home or any other property.

That being said the issue gets a little more tricky when it comes to government run property, with government run property I tend to come down on what I think is a reasonable position of if you are not required by law to be there then the individual government agencies can restrict gun possession provided there is not a superior law preventing that.. an example would be many State governments preempt local parks depts from passing rules prohibiting carry in a public park.

>>>And one can drive as fast a she wants as long as there is no accident?

Generally speaking I believe in enforcement of Reckless Driving Laws and less on arbitrarily defined laws. For the most part speed limits are less about safety and more about revenue generation for local government. Even under todays law if you are driving the speed limit and a cops believes that is unsafe for the road conditions you can be ticketed and even arrested.

I do agree that the specs do not look enticing on paper, compared to say the Asus ones, but in my experience they last longer.

Whenever I visit my parents I usually bring replacement hardware for whatever is broken. When I first got them their Airport Extreme, I replaced it after 5 years. I got them an Asus router with a really impressive wifi range, but it broke after just 1 year. Now they're back with the latest Airport Extreme.

It's a bit pricey for the specs but it's very reliable. I use 2 at home, that are bridged via gigabit ethernet, and they're pretty good. My only complain is that they don't have VLAN support (IPTV) and their wifi range is really bad.
OpenBSD has had VirtIO (supported by KVM, VMWare and now virtualbox too) guest support for a while now.

AWS uses Xen and domU support is a lot more invasive - OpenBSD had supported it in the past but I believe it was dropped?

> The interesting part of the conversation to me is the plateau itself - according to many people, all people and especially individuals are the same, calories in minus exercise equals weight gained (or lost), there is no such thing as flux, every day is exactly the same, literally the only variable is your weight, and that hardly changes at all day to day.

I've never seen anyone claim that calories in / calories out will have an immediate impact and should be visible on the scales within days. On any given day your body might hold onto lots of water, so you don't lose weight. Later you might get really dehydrated on a hot day, so you appear to have lost weight, etc. etc. Times one million variations for why you won't see "results" "instantly".

Don't for one second think that any of this is measured on the scale of days, or weeks. You are completely deluding yourself if you think it is.

A scale of months hardly makes sense either. Do everything for a minimum of 3 months before you expect to see a difference, on the scales or in the mirror. Everything takes time, and you're in this for the rest of your life, so what's the difference anyway.

> Correct. However, you can absorb less than you eat! Eat 2000 calories, absorb 1500, poop out the rest, gee, I wonder if that might have any effect on weight loss?

It won't, because that's how your body has been functioning for a long time.

If you're trying to lose weight, you just have to feed it less, who cares how much it's extracting, it's completely irrelevant.

Like I said, it doesn't matter if you're in a car that gets 30mpg or one that gets 50mpg, as long as you put less gas in the tank than you are using, sooner or later the tank will run out!

Stop trying to make this harder than it needs to be, or more complicated that it needs to be.

Consume less calories than you burn, and in the long run you will lose weight.
Thanks for this. Time to go fix my code[1].

He definitely used his own experiences with epilepsy and pre-epileptic visions when writing The Idiot, but that was much later. I think The Double had more purely literary antecedents. Doppelgängers were an established trope by then, which Dostoevsky got from the German romantics—people like E.T.A. Hoffmann, who specialized in stories with weird phenomena that could have a natural explanation (e.g. the mentally ill hero's delusional imagination) but are uncanny and probably magical all the same.

The Double was only Dostoevsky's second novel but it was one of the best things he ever wrote. It's fabulous! And short.
>> "Go's new garbage collector is a concurrent, tri-color, mark-sweep collector"

So basically, it's the same GC that Mike Pall had planned to implement for LuaJIT 3.0. Too bad Mike recently announced he was transitioning away from doing daily LuaJIT work.

This looks comparable to Sequel and seems straightfoward enough. Still, when I need a full-featured tool, I prefer sqitch[1] - does what this does without requiring numbered migrations, treats database changes as commits (very similar to git), and includes the option of running tests to verify schema changes.

That said, this looks good for cases where you have a node project and want to keep your tooling on the same platform.

Why do you say this is quite different from symbolic differentiation? It seems every function (including addition, multiplication, etc.) is simply augmented with a description of its total derivative, and these derivatives are combined via the chain rule, which is just how symbolic differentiation would normally be carried out as well.
Because what everyone wants is more invisible closed-source software running on underpowered CPUs? Not to mention the limitations on performance, capacity, and reliability scaling that would be inherent in binding the database instance to a single disk device. Or were you suggesting that each of these tiny controllers running deeply proprietary software should also form a distributed database in concert with host software or HBA controller firmware?

To say that this is not a good idea would be putting it mildly. The existing efforts to build more functionality into disk drives, starting with FDE and now with some object-store-like interfaces, sounds real appealing at first. Less software to write, functionality everywhere, disks seem to Just Work today so wouldn't it be nice if they could Just Work in some more ways too. However, as soon as you start thinking about building something larger or more interesting than a toy, it becomes apparent that the disk drive is the wrong place for this. The knowledge of the problem is not present at that level of the system, and the interfaces and processing power are inadequate to express it. The problems of error recovery, scaling, and debuggability cannot be solved there. It might be useful for a few of the very smallest consumer-grade applications where none of these concerns are significant (nor likely to be solved by a higher-level vendor anyway), but it's not generally viable.
I agree - an entirely new architecture with nothing to speak for it (no FPGA code to try it out, no production chips, just paper this, paper that). I'm much more impressed by Risc-V - it exists in a format you can actually use.
Good GC is an open problem. Even though there has been much work done on the subject, there is still plenty of room for improvement!

Server GC, for example, typically tends to be less concurrent to improve throughput. Client GC is more responsive, but also sacrifices throughput. Since Go is positioned for server work, it is very interesting that they are choose what is typically seen as client-side priorities.
The average person (American, anyway) has no financial discipline and will spend every dime they make, and then some. If they simply "increase their income" without the fundamental ability to save / invest, they won't get anywhere long term.

BTW, I'm very good at increasing my income. I usually bring home an extra $2K to $3K a month on top of my day job, and am always looking at ways to grow this.
I don't know the technical details of this project, but it's well known that Hubble's basic design matches the spy satellites being manufactured at the same time. They changed the size of the mirror so they could source the part from the same manufacturing resources as the spy satellite program.

Another fun bit of trivia is that at one time the NRO (folks who operate the spy satellites) offered two they had in storage to NASA.

So in general I'd say it's a safe bet most of this technology is dual use. It's likely the secret squirrel folks are ahead of what open science projects can use however, given the resources available.

I suspect at this kind of resolution bandwidth getting the images down from space might be a big limitation.
It would have saved me a lot of time, that's for sure. And here I thought I was being responsible and informed by reading the man page.
In that case, the problem doesn't happen because we are minifying the files, but because this particular implementation of the minifier has a bug. I guess...

People misunderstand what open-source really is. There is a selfish reason to maintain open-source projects. Developers are above fixing their own problems when working on open-source. This is the only reason companies and developers invest in open-source.

Hence, the type of projects that become massively successful are components, frameworks or platforms... things that are re-usable for the solutions or apps these developers are creating for their companies. There is real economic value being unlocked there. Recent examples being Docker, AngularJS, etc that are supporting by lots of companies

Creating an app or solution is a whole different ballgame. They are usually side projects because there is little or no incentive for a company to take away resources from building their own apps/solutions, to save a few bucks.

The idea of needing a licence to run any business seems absurd to me. In Australia, you need to register for an Australian Business Number, but that's for tax purposes, and it's cheap and easy to do online. Even forming a corporation costs less than $500 and a few days waiting. (literally - it's 2 days after the government receives the application form)

There are restrictions around certain trades (electricians, doctors, etc), but they're the exception, not the rule.
Hi andybak, I work on the Sandstorm team and it seems pretty clear that you're not an idiot.

I'll see if there's something we can do to make this essential UI element more discoverable.

To some extent, it's a matter of learning about Sandstorm -- Sandstorm's role in the web app ecosystem is basically to add sharing & access control, so maybe everyone has to learn this. But hopefully we can help people figure it out more easily.
Schools have created this problem by meddling in the parenting process for the last few decades. Calling the police if the kid walks home by himself. Calling social services if they come to school without lunch. Involving juvenile justice authorities if two kids settle an argument with a bit of fighting.

Now after they have parents thinking that one false move and their kids will be placed in foster care, they complain about overparenting.
"What about melatonin?"

It's very safe in terms of its non-toxicity. But the jury is still out on long-term effects like daytime drowsiness, slowed reaction times, etc., resulting from taking melatonin on a regular and prolonged basis.
To be clear here: You can be a perl newbie even after you've been writing Perl for decades. I know this because i sometimes see code like that in companies that don't value their employee education, or heck, their employee. Period. You'll have a guy who's been writing Perl for 15 years and never got past the small 500 word tutorial he once read back then. He may be old and have the years, but he's still a newbie since he doesn't know shit.

That said, i've never met these people outside of said companies and especially not on the internet and most decidedly not anywhere near any sort of perl community. They've all been strict 9-5ers for whom the coding is a burden to bear to pay the bills and nothing else.

The people who're old and in the community? They're on the same Kwalitee train as everyone else.

I hope you don't stay embarrassed. We could improve parts of the interface, and we need feedback like this to know what people think is going on, so that we can decide how to change the interface to show people what is actually going on.

The problem is you're using "supernatural" as a semantic stop sign (http://lesswrong.com/lw/it/semantic_stopsigns/). Would it help if I rephrased it as: given this natural phenomenon reported by thousands of people in a wide array of circumstances, what is a possible scientific explanation?
There are reasons for business licenses. From a current HN story:

"Behind Deadly Tianjin Blast, Shortcuts and Lax Rules"

One partner was the son of a local police chief, the other an executive at a state-run chemicals firm. After meeting at a dinner party, they started a company here to handle the export of the most dangerous chemicals made in China, promising “outstanding service” and “good results.”
I'd honestly blame parental expectations more than the schools for this.
> They could ask her, "when you wake up, how likely will you think that the coin was heads?" and get the same (correct) response of 1/3.

Exactly. Let's stretch the example to the extreme, if you get heads you get woken once, if you get tails you get woken 1 million times. Now say you run this experiment 10 times and you happen to get 5 heads and 5 tails. You'd be woken up 5 million and 5 times. And with each wakening, the chance of the coin having been heads isn't 50%, if you'd say and guessed it was heads every time you wouldn't get half of them right, you'd be statistically wrong about 5 million times out of the 5m and 5 times. The correct answer is 1 in a million, and if you'd guessed tails on every awakening instead you'd be wrong on average only once in a million.

It's this chance to be correct or incorrect in your answer when waking that would inform the question that was posed 'When you are awakened, to what degree should you believe that the outcome of the coin toss was Heads', which then would be 1/3.

Actually he wanted to use a quad-color implementation, which AFAIK is a Mike Pall tweak of a tri-color collector.
Your assumptions seem pretty fair to me. We have to do a better job of teaching people that the topbar contains grain-related functionality -- specifically, functionality that is mediated by Sandstorm, like access control.

FWIW, the first version of Sandstorm let you copy/paste the URL from the address bar, and I'm definitely a fan of that model. But, a lot of people are uncomfortable with that. It "feels" insecure. So we're trying to find a happy middle ground, where the people who like URL sharing can use it, and those that don't can avoid it. It will take some experimentation to get right.

There was an interesting subthread on this, on another article entirely, a while back:

https://news.ycombinator.com/item?id=9280134

Meanwhile, I once answered a question from a person on Quora whose premise was that people can imagine "audio and visual" stimulus, but not "odor, taste, or touch". I suspect that was based on the asker's own peculiar dominant senses and style of memory, as I addressed in my answer:

Some general points/comments.

1. Most new developers/entrepreneurs always under price their product/service. If you are new to this and the price feels a little uncomfortable you are probably getting closer to its real value.

2. Discounting screams you don't know the value of your product/service. Try not to "discount" your product/service, instead A/B testing is smarter to set some parameters. Also, I'd second what taprun says on discounts too in his comment.

3. Set your pricing not based on what the service costs you to operate, develop, maintain etc. Set your pricing based on the value you provide to the client.

4. Don't immediately reach change the price when you are starting out. Evaluate everything equally to price, it may be who you are marketing to, product/market fit etc. And much of that is far more impactful than just price alone.

5. Try to keep you pricing scheme simple. The easier it is to understand the better. Ideally I like to see at most 3-4 "levels" of pricing, more than that and users start getting confused what to select and are more likely to bail and not try any of them.

6. Experiment with free trials to see if it may help your conversion rate. I can't say it is ideal in all situations nor does it work in all, but it is worth evaluating.
Thanks for the very useful tip!
The question is actually: "given that I have woken up, what is the probability of heads?"

This is the question that is disputed by sources in OP. Both sides are addressing the same question.
But is that agility good for consumers? In my world, it's not. I deal with a lot of seniors, and you know what they hate? How people in Silicon Valley feel obligated to move stuff around every six weeks.

In fact, most people not in Silicon Valley hate it. And something like Sandstorm puts the user in control of whether or not their stuff changes. Someone can have auto-update on, and have the latest everything, and someone else, even on the same server, can choose to keep a stable version that does what they need.
I'd be very interested in a hackpad demo on sandstorm. It's nice to see Etherpad and Wave though!
I think that the schools where kids show up without lunches and the schools where parents are doing their children's homework are very different places. The article even concedes that the issues that the authors are trying to fight against are very much "first world problems" at the end of the day.
Apple is reportedly planning to make its own movies and TV shows
>We have no information

We do, we know that we are now in the experiment. In the case where you don't wake up on heads at all, have you learned new information upon waking? If yes, why don't you learn something anytime the relative probabilities differ?
These kinds of projects really highlight how awesome embedded linux really is. It's the marriage of everything small embedded systems can do (gpio, analog inputs, low level communication protocols, ability to run on batteries, etc) with PC level specs, and the breadth of software that linux provides (every networking protocol under the sun, audio/video processing, countless languages to program with, etc). Best of all, the only thing you have to buy is the board, of which there are several offerings at $50 or less.
Unpredictable latency is a huge no-no in these days of responsive server applications. Long GC pauses are just not acceptable to many server developers, so I don't think it's correct to consider it only a client-side problem. If you look at the mechanical sympathy mailing list, you'll see a large group of Official Knob Turners for the Java garbage collectors discussing their trade.
Nope.

He works with the psychic to agree on a test of what the psychic claims to be able to do, with low enough probability that you can't pass by chance. (I believe the threshold is somewhere below 1/million.)

Doesn't matter what ability you think you have. A test can be set up and agreed to.

A number of psychics have wound up concluding that their abilities won't work under the influence of unbelievers. But nobody that I know of has complained that Randi was not willing to set up a fair test.

> Today 16 gigabytes of RAM costs $100 and CPUs come with many cores, each with multiple hardware threads. In a decade this hardware will seem quaint.

This is a potentially dangerous worldview. While it is true for the server/desktop/laptop segment, it is less of a surety for phones, and downright scary for smaller, low-power embedded/IoT devices.
The point is not that latency doesn't matter. It's that throughput and latency are more or less a fundamental tradeoff in GC, and latency isn't the only thing that matters.
