The Next Secrets of the Web
HERE’S THE GIST:
- A secret is at the core of every big innovation.
- Entrepreneurs should focus on discovering secrets about human behavior, which are cheap to discover but can have a massive impact.
- Behavioral secrets are plentiful whenever major changes in interface occur.
- For startups, secrets need to quickly turn behavioral insights into network effects to sustain competitive advantage.
Great idea and great design!

You'd "need" (in the handwaviest sense, because nobody had designed a crypto token based on one-time pads here) OTP content for every authentication attempt.

I just got back from Aruba, and would have loved to have a map (no international data plan). Could definitely see the draw.
I see a lot of Chinese brand tablets in China. That and the Galaxy note are crazy as hell here.
Microsoft didn't make the same claims, but they showed the same lax attitude toward security for years. Apple only needed to see a few malware outbreaks to come to terms with reality.
I used it and it's not bad at all for a "playtime".

But since I've no idea how to write code in Closure, it's not useful for me.

What I want is a Python version. A Python enabled Light Table would definitely replace Python's REPL for me.
Apple won big in smartphones, but Android has a bigger marketshare. Competition between all smartphone vendors have made the customer the biggest winner in any case.
So like he said, over a decade ago.
To reply to the post you deleted about downvotes...

I didn't downvote you, because I appreciate you bringing up a relevant technical concern.

But sometimes people bring food over to my house and I just eat it. At the alpha stage of development, I think it's reasonable that your option is to not download.
Particularly the power connection (capable of carrying 17 to 95 watts for laptop-class and desktop-class chips).
If it was intended to prefer the author's title, even "It's playtime - Light Table Playground released" is far better.
Inside The MIT Media Lab Where Technology Can Sense Emotions
While Apple's install base is steadily growing, I still think they have a significant advantage in obscurity that grants them security.

i.e. Why do virus-writers target Windows? Sure, it has the largest install base, but Windows also runs a lot of servers and embedded systems. These two things are the real jackpots. What's taking control of one person's computer compared to taking control of a server with credit card information or a system running a billboard in Times square? Apple doesn't do embedded systems and their servers, while some do exist, are exceedingly rare.

Is security through obscurity enough though? That depends on who you are and how interesting your data is.

Beam-twisting "phase holograms"
I think that Angry Birds and World of Goo only work because of their freedom. Chess, Tetris and DROD work because they are beautifully simple and discrete. Minecraft took a "mathy" world to the extreme while AAA games seem to explode in organic freedom. Cut the Rope uses a physics engine but enforces "one right way" through its level design.

Maybe it's not so black and white, but rather designers make parts of a game discrete until it becomes simple enough to be fun. Whatever it is, the complexity of this game concept feels overwhelming to me. It's a bit like this physics-based Tetris, I would try it for fun but only for free and for five minutes.
Looks great.
A couple of questions:

1) Are the maps route-able? Can I use this for turn-by-turn?

2) Can I download the entire world OpenStreetMap and use it with this app? For a round-the-world I'm planning, I'd like to get maps of everywhere.
(For example, last time I drove from Alaska to Argentina, and I'd like to be able to use the OpenStreetMaps of everywhere in between)

Thanks!

I did my senior design project on an infrared related area. Things look really weird in the infrared.

http://imgur.com/SLGvT,y79tC
First image - can you guess which one is diet coke, and which one is water?
Second image - I was shining a 940 nm IR LED through my hand, you can see veins.

I can make this more interesting!

So webcams generally always respond to IR light. If you look at the front of your remote with our camera phone and press a button, you will see a bluish whitish light. Well, that seems a little weird at first. The light that's coming out of the LED should be closest to red... Well, when CMOS camera companies make their cameras, they heavily rely on the blocking abilities of the IR filter. They want to get amazing signal to noise ratios for the visible spectrum, and the combination of materials that does this is also absorb IR light as well. They can just use a coverall filter to get rid of the infrared light.

Here's the spectral response for the D200 - http://www.maxmax.com/images/Cameras/Technical/NikonD200_Spe...

This has got to stop. I don't know if the rewriting is getting especially bad lately, or if it's just happening more to the articles I'm reading.

He's already altered the page title to "It's playtime - Light Table Playground released"...can we at least get someone to include the subtitle on HN?
The people at Google have and are continuing to attempt significant "outlier" levels of financial and software technological success.

Should they expect to work a 9-5 schedule?

If achieving success at a level that might require that you to sacrifice a bunch of your family life is your thing, then I guess that Google might be a place for you. If it isn't, then you don't really have to work there.

So much vitriol in this thread toward a person who made the choice to work hard and be a part of a company that expects its people to produce. It's not like there are Google slave camps where they put you on an island, take away your passport, and won't let you leave.
Moreover, the legend of the über-productive employee who never sleeps is a double-edged sword and can demotivate the employees that person touches in ways that far outweigh the direct positive impact to the company that person has. As stated above, it's one thing to work 12-16hr days during start-up phase, but if you're doing it as a matter of fact when you're a 30,000 person company, frankly you're doing it wrong -- even if you're the founder, owner, board member or C-level executive. Leading via exemplary personal performance and ethics is one thing; driving those values throughout the organization is far more important.

the BBC piece is one of those tawdry - hype up a new conspiracy - pieces that 'journalists' use to try and add some interest to story where everybody has the same news. It was the same with all the new 'theories' around the Titanic sinking a few months ago.

ESR's point is perhaps best made by Einstein's quote:

"If I am proved correct,the Germans will call me a German, the Swiss will call me a Swiss citizen, and the French will call me a great scientist.

If relativity is proved wrong, the French will call me a Swiss, the Swiss will call me a German and the Germans will call me a Jew."

People who don't know an Entscheidungsproblem from a hole in the ground will latch onto this to claim Turing for their own team that: "He was great and English", "He was great and from Cambridge", "He was great and worked at Manchester", "He was great and at King's" , "He was great and gay:, "He was great and a marathon runner" ..etc...

This is a very interesting heatsink design. That said, having a finned heatsink spinning at 2000+ RPM seems potentially dangerous, especially if someone were to touch it with their bare fingers while it's operating.
> I strongly suspect that the "feature phone" market is going to largely evaporate outside developing nations within the next few years.

I strongly suspect that's going to happen in developing nations as well.

You can get an unlocked 3G Huawei android 2.1 phone for $80 in the US. The cheapest usable unlocked feature phone you can get in the US is $15-$20. (You can occasionally get a $10 2-band GSM phone that has no screen and can't do texts -- I'm ignoring that)

Feature phones are going away. Developing nations will just have less capable smartphones, with lower resolution screens, slower processors and old operating systems. But they'll be almost entirely smartphones.

"If failures are totally independent"...that's sometimes a big if, especially on cloud providers.

Glad I'm not the only one who thought this. I'd appreciate either signed packages or SSL, otherwise this is very, very insecure.
Clojure still generates a lot more garbage, especially during bootstrap. This can be seen easily with VisualVM on the desktop, comparing hello world in the two languages.
You need to be really careful when using object pooling and carefully consider two things: synchrony and lifecycle issues.

Synchrony issues occur when sharing an object pool among multiple threads. If you're sharing an object pool and using an unsafe data structure you will run into concurrent modification exceptions. Another issue could also be that using a thread safe data structure (or more simply a syncrhonized method) will lead to huge performance degradations because it is a central point of contention. A third issue with object pools is that if you have multiple threads using an object pool it might fill up your entire heap with cached objects.

The lifecycle issues come into play when you ask the question, "Who returns the object to the pool?" For example you could have 1 thread passing an object to another thread and then returning the object to the pool. If not considered you could run into a possibility where 2 different threads are operating on an object as if they are the sole owners leading to unexpected results.
I started picking up Perl (as my first programming language) in 2003 while working in a genetics lab. I used it for years on a number of bioinformatics projects due to its strengths in tackling disparate sources of often irregular information. Recently I've been using it for the Kaggle Facebook competition simply because I can iterate my designs faster than in any other language. I'm looking forward to learning a few of these more newfangled modern appurtenances of Perl.
I've been reading back and forth between this post and the docs and I'm still not really getting it.

Is this just a way of registering a single callback to respond to error events that could be emitted by different operations? What are some examples when this would be better than handling error events individually?

Is it sort of like a try/catch for error events?
Most vulnerabilities are unrelated to the actual OS stack and exploit other stuff. In that particular case is even wrong to say it was a "Mac virus", since it was a Java exploit and could have affected any system with Java installed. The point is that it remained unpatched for too long on Apple's Software Update.
DSL and dial-tone are completely separate services, that only share a copper line. Verizon doesn't require you to purchase dial-tone in order to get DSL. The only reason I can think of for AT&T to do so is to prop up their telephone business.

Ask HN: what is the best screen protection for my retina macbook?
I will be getting my new retina macbook this week. My old macbook is a white 2008, which now has the imprints of most key corners and one chip from a piece of sand. What are the best products to protect this new screen?

Also, what have been the best skins for the previous generation macbook pro?

I'm looking at the Moshi and Bodyguardz clear skin.

Also, what are the best sleeves? Any experiences with either the Rickshaw or Saddleback Leather sleeves?

Why does the quality of a news site like slashdot, digg, reddit, or Hacker News deteriorate until it reaches annoying levels? Because if it didn't, then more and more people would join, reducing the average quality of the participant pool.
If anyone is going to update their software manually, surely it's going to be HN/code editor users (I know I do). And anyway, it's a preview release that people won't be using as their main editor anyway. Install, play around, uninstall.

Reading through the reviews on iTunes (which are generally positive), I noticed that there were a number of mentions of how their city/region was not on the map, and after they contacted the developer, that area was downloadable.

Theoretically, why isn't all of the geography downloadable when given certain parameters? I'm unfamiliar with how OpenStreetMaps works, so was just curious what kind of manual tweaking/map-downloading that you, the developer, have to do.
All the noise the media is doing around this case is to actually drive a demand for antivirus software for Mac. You don't see any article mentioning installing software from trusted sources (like Mac App Store), digital signing, configuring firewall, keeping software up to date, etc. Their whole point is to compare the Mac platform to the Windows one, so they can conclude that installing antivirus software is the obvious choice.
This is what I do for Android games -- design things to be mutable and pre-allocate however many I'll need during a level. You also have to avoid foreach because it creates objects.

This is an area where C# is better. You can create classes or structs and structs go on the stack. Structs are a lot more appropriate for objects like rects.
If you were the director at a heritage language Asian school (whatever that is) who just wants a website that represents the school well, you might find it more compelling. Not everybody is as cynical as you or I. Because of this, pointing out "This wouldn't work on me" isn't particularly illuminating unless you are the target audience (and maybe not even then).
I'm the primary person behind this, and will answer questions here.

Since it's a donation campaign I wasn't sure if it was kosher to self-post it to HN, but raising funds isn't why I did it. I know there are a lot of people here with finance experience, and I'd be interested in engaging with you if you have something to say.
When I was getting started out I had a lot of success going to local tech meetups for the technologies I worked with. After showing up to enough meetings that I was a familiar face I did a few presentations. Afterward I was approached by group members and a couple small local dev shops looking to sub out overflow work.
It's early and we honestly didn't think down those lines. Ultimately, the deployment mechanism will look different than this, but this was the path of least resistance. At the very least though we can do a few of these things to remove some of the danger - we'll get on it.
I will have to agree with point #1. I don't care about the UI, period, the end.

Many of the questions in this comments thread (e.g. safety, e.g. vertical mounting, e.g. cost associated with the bearings, e.g. the basis of the 7% figure) are already answered directly or indirectly in a year-old Q&A article that was linked from TFA.

Very interesting - we applied to YC W11 with the idea for OpenRent (http://www.openrent.co.uk), which is surprisingly similar, but failed at the interview stage.

We launched a couple of months ago in the UK, and it's going well so far. The only problem, which I'm sure you will also face, is reaching out to landlords in an effective/targeted manner.

Very happy to see people attempting to improve the rental market though, and I wish you all the best. If you guys ever wanted to get in touch, feel free to at [redacted] - would be happy to share our experiences.

Good luck with the rest of the launch!

> 4. The article also likes to try to downplay everything negative. For example, "It is often repeated that the chemicals caused him to grow breasts, though Turing is only known to have mentioned this once." The second clause seems to be the most important.

Well, thank goodness, maybe he didn't actually grow breasts. Must not have actually have been that bad being forced to take hormones for no good reason.

There's also a very, uhm, disheartening tone that a lot of commenters on that blog post are taking -- what sort of people is ESR attracting? People are suggesting that Turing's castigation was a preventable result of his homosexuality he should have predicted and avoided. "Just stay in the closet and shut your mouth."

Gross. Really, really gross. ESR should be ashamed.
It's a bit strange to me that one of the recommended optimizations is to create fewer objects in a programming language that is heavily object oriented.

Tell your friends, I'm sure you will be able to get some small clients to start off with that way. You can't expect to be getting big clients from day 1, unless you're exceptionally lucky, you just have to grow bit by bit. Build a portfolio, advertise online for free for your local area. Last but not least, under promise, over deliver. It will give your clients a more positive feeling about you and will help with word of mouth. Make sure you give yourself enough time to make deadlines.

I missed the article last time, but I had this thought too, on reading it this time around.

The challenge, obviously, is moving data on and off of the spinning element. I assume one would stack the CPU, the GPU, the mobo, the RAM, etc, up along the axis of rotation. It's certainly easy enough to get keyboard and mouse and audio get on and off the spindle via wireless... but what are the costs (in money and in latency) to get higher-bandwidth signals on and off, like video, and like main storage?
