Getting a VPN account from some service like witopia.net is not rocket science. People just need to be educated that they need a VPN account if they want to use a publicly shared network without compromising their privacy.

(Of course, as boyter pointed out, a VPN connection doesn't protect you on the general internet, but it does protect you where you're most exposed.)
Automatically generating a concept index for freeform notes
Interesting article. But I'll wager this advice is harder to follow than it seems.

For example, he mentions that the founder should at some point concentrate on the business and not on the "grunt work". While this is obviously true, the point in your business's life at which you decide to stop coding is of critical importance. Another founder could well give the advice "don't be afraid to get stuck in", or "beware of retreating to your ivory tower", and their advice would be equally valid.

As always, the key is balance.

Possibly because there's a subtle but definite difference between an experiment carried out on 51 subjects from which 1 stopped before 300V and one on 50 subjects from which nobody stopped before 300V.

Timing your startup? Do it ASAP. If it fails, do it again.

I doubt very many startups at all have timed their run intentionally. More likely, they've been inspired, run to market before their motivation fizzled, and things have fallen into place (right timing, met the right people, etc).
Impressive stuff. I wish they didn't use stock photos. No matter how nice the web design is, stock photos make it all feel "cheap". Please either take a camera and make your own photos, pay a professional photographer to make them for you or create a design that doesn't need photos.

Once again, avoid using cheap stock photos. (Same goes for avoiding using cheap production library music for videos on your site.)

With usenet you did give permission, the inherent nature of usenet required messages be copied across large numbers of independent servers with different access policies (free, charging, etc) and mechanisms (nntp, email, web). Hence by posting to usenet you implicitly granted permission for your message to be copied (this was actually tested in court a few times in the 90s).
That git snippet is tremendously useful. Hat tip.
This is a concrete example of an intuitive fact. There is a limit to how much a government can tax the "rich." This limit will be the tax differential between locations, investment vehicles, or over time, plus the cost of moving the money.

An example of tax rate differences by location is Michael Arrington: California vs. Washington (http://news.ycombinator.com/item?id=1736265).

Ballmer's sale appears to be the result of a time-based tax rate differential. IRAs are also time-based tax rate differentials: the premise is that the investor defers paying taxes on the IRA investment until he retires and (he hopes) is taxed at a lower rate.

Examples of investment vehicle-based tax differentials are tax free (government) bonds, Roth IRA (interest is tax-free), special "economic investment zones", etc.

A 1000 times yes.

But, with one proviso:

It is ethical, right, and good to cut off all ties with people who actually do violate social rules and hurt others. It's better for everyone, including the person who did the deed, because they will learn fast that it is unacceptable.

There should, as the original post says, be no exceptions for skill or usefulness.

In my time, I've entirely cut off people who I've learned have hit or abused others in any way. I don't care if it's a man sticking his hand in a woman's pants or a guy hitting his boyfriend or a woman verbally abusing her man, or any parent mistreating their child. (All humans, of every gender, age and background, do evil and hurt each other equally.)

I've taken a lot of heat for this, and lost opportunities for money & fame, but you know what? I can sleep easy. I'm not losing my own sense of what's right by drips and drabs of attrition.

That said, you can't make it top-down. It'll never work. There's no way to dictate that others do this, no community "rules" that will work, unless people are willing to look hard at themselves and ask, "Is this the kind of behavior I want to condone? Do I want to even be in the same room with a person who'd act like that?"

That's trivially true.
Timing your startup? Do it ASAP. If it fails, do it again.

I think this is a bit too glib. If it is evident to you that the timing is not right for your startup, the prudent thing is not to launch blindly, praying for a miracle or a chance to try again after failure-- rather, to adjust your idea/product/service to fit the market conditions.

It seems to be one of those few places where people will be content to be absolutely miserable in their jobs for 20 years.

Somebody should tell the Chrome team that. A recent version of Chrome changed the mixed content warning indicator from a relatively innocuous "padlock with a cross" to an alarmist "skull and crossbones". We got a lot of complaints about that (due to not yet having built the "ridiculous image proxies" kneath complains about above).

It seems like they may have thought better of this change, since my current version of Chrome (6.0.472.63) seems to have gone back to the padlock-and-cross.

Show HN: Findsimilar.info - my weekend project
I’m often interested in buying some book, film or piece of music based on someone I already know I like. The logic goes something like – ‘if I like this I will like something similar’. Now it is already fairly easy to do this online by using one of many websites providing this information but it is a distraction to do so an requires navigating away from the work I am doing engage in some website for a couple of minutes.
I wanted something quick and easy that would allow me to send off a request in less than 10 seconds then get back to my work. The information is now waiting for me when I’m ready to disengage from what I’m doing.

Its also command line-esque which I prefer than clunky interfaces.

I use Tweetie for Twitter which is always open and in less than 10 seconds I can have it open with a quick command line style query written and being processed while I get back to work.

To give it a go have a look at http://www.findsimilar.info to see how it works and what you can search for.
I prefer it. So far it has been easy and somewhat more reliable. It is also very frequently updated.
Web browser pioneer backs new way to surf Internet
You are correct that these issues need to be addressed, the FAA already has a system in place to prevent aerial collisions of commercial and private planes. I'm sure the existing regulations can be modified to be more suitable for uavs and city-scale flight patterns. For example, stay at odd-hundred elevation for north and east travel and stay at even-hundred for south and west travel.
Why only mobile? We need something like SproutCore, but easy like Rails.

Backbone.js maybe?

Yes, this is why the concept of energy is given such a prominent position in physics. It is a great tool for predicting what might happen even when the detailed mechanism is unknown or seemingly impossible.

I haven't yet taken the time to understand the details of these explanations, but when I heard about this cart I immediately thought "hmm, the wind is blowing, there's energy all around, so some tricky person can probably figure out how to make use of that energy; hence, it's plausible".

Of course, the flip side of this principle is that physicists can be driven to spend years and years and years trying to extract energy that is obviously there, but that has no known mechanism for getting it out. The classic example is nuclear fusion. Everybody knows it's energetically favorable; nobody knows how to get over or under the activation barrier in any useful way, other than "build something the size of a star".
Great, thank you. I'm going to dive in and give homebrew a proper go.
> [Boats] can go faster than the wind when then wind comes from the front, not when it comes from the back.

True, but it may be worth of mentioning that no regular sailboat (i.e. without underwater propulsion) can go directly to upwind (0 degrees). For modern sailboats, the maximum upwind direction is roughly 45 degrees, the sidewind (90 degrees) being the most optimal.

I specifically said "amateur school of successful language design".

"Great" is subjective, but nearly all ground-breaking languages invented after Lisp are all Lisp-like (don't look at syntax.)

Industrial, imperative languages are nearly always "designed" on a whim. They're all incremental improvements over Algol, and they're probably what you're talking about if you're of the great majority of the programmers. As of late, they're more Lispy than you can imagine.

Except for a specific school of Lex & Yacc languages out of New Jersey, the great majority of professionally designed languages (i.e. by people with an appreciation for formal language design and semantics) have been Lispy and functional; characterized by clean minimal core, well specified semantics, even proven, and self-hosted implementation.

Just to throw the discussion a bone and offer some perspective; I consider ActionScript 3 "Lispy", but not AWK or C++.
The target seems very mobile-specific. HTML5 is better supported on mobile, and the proposed model sometimes fits "desktop" web apps, and almost always mobile web apps.

So yes, buzzword, but it fits.
> That's because the maths guys don't actually know about the applications.

That's often a big part of it: Someone who isn't a day-to-day user of something sees an issue in it and recognizes that it could be done in a cleaner way, but explains the solution in their own terms rather than in the local language.
I would say that "smarter over time" is the wrong conclusion of the Flynn effect.

1. I assume this is precise, not conservative GC?

2. How do these work with the new concurrency (threading) system that as I remember Team Parrot was going to write?

Ideally, for the multicore future that is now today, I'd like to see multiple simultaneous mutators and scavengers without a stop the world requirement. That said, stock HotSpot doesn't supply the latter, although Azul has done some neat stuff to extend it and apparently Do A Right Thing (their Pauseless mark and compact GC and their open source release of that in their Managed Runtime Initiative).

It would be nice if Parrot can someday do this without extreme pain.

They may have had Appel's "Garbage Collection Can Be Faster Than Stack Allocation" (http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.39.8...) in mind.

Also, the technique described in that comment (forking processes with finite lifetimes, allocating but not freeing, terminating and letting the OS clean up all at once) is also what Erlang does, and it seems to work pretty well in practice. Each process has its own arena, for allocation purposes.

As others noted, this is largely a CYA clause. I suspect the real reason is because UAVs are a legal grey area as far as the FAA regulations are concerned. It is generally accepted that regulations for R/C aircraft also apply to UAVs. The tricky point is that the FAA regs specifically state "for recreation". So you can legally fly an R/C plane and take aerial photos as a hobby. However, if you sell those photos then now you've broken the law. (R/C clubs recommend selling one ground photo and giving away the aerial ones to skirt the issue). The AR.Parrot folks know the regulations and are simply trying to distance themselves with boiler plate.
