I too am a huge fan of SQL, what mysql and postgres has given to the world and how it has inspired and set seeds in many of us to use open source, contribute to open source.

I am dipping my toes into couchdb, just to see what all the noise is about.

Still getting my head around map,reduce and the fact im writing in javascript. All that aside the biggest exciting factor for me.

It is so much easier to write custom functions for it than SQL. ( Mysql, and yes I only tried via phpmyadmin )
The problem with this article is that he is testing as ONE ACTIVE USER, as if only one person was ever using digg at any given time. Of course the queries are going to return thousands of times faster. Try replicating digg's actual environment, which I know nothing of, but I know the site gets a ton of traffic and probably has between 10-50,000 users online at any given time.

Now run the same queries you were doing again on your test machine, but simulating 50K users online at once. Oh, and don't forget about thousands of writes per second, which was conveniently not part of this test. What's that you say? The performance is suddenly complete shit? Color me shocked.
There's something of an HN meetup in the works in Tokyo either April 2nd or April 9th but details are still getting hammered out by email.
FCC approval is actually quite easy and affordable (less than 10k), as long as your equipment passes first time.

The best way out is to buy a dongle or module from a 3rd party who has already got approval for it. If the RF module has approval then you don't have an issue. You still need a different kind of approval for your electronic device, but they are just reselling a 3rd party device so no issue there either.

I haven't made a mobile phone - instead I have worked on other RF devices. Perhaps there are issues I am not aware of (a public mobile network probably has a lot of checks and balances that are much more expensive)
Are there actually any cases in which laches had been successfully invoked in a patent dispute?

For what I understand, unlike trademarks, patents don't have a provision that you should protect them or enforce them. In fact that's why defensive patent portfolios work, isn't it?
Lens flare is kind of nice sometimes. I like how CG movies add it in to make it look more realistic.
Given the number of people paid full-time to work on open source, I don't think the "you shouldn't need to be paid to work on open source" argument works at all.

Again, they need to be paid to learn this stuff?

Yes. You could think of it as sort of an internship. Most colleges do not cover the sort of stuff you need in the real world -- I know mine doesn't, so GSoC was invaluable for me.

I don't think direct response is the only way to go (I assume you're referring to informercials), especially with all the online marketing you can do. I'm sure there are also resellers which would let you drop-ship and not actually distribute product.

Another option is to get a patent and license it to someone.

I thought this Jan cover article on Wired was really good about production:
http://www.wired.com/magazine/2010/01/ff_newrevolution/
I don't quite follow, but I'm also new to mini-Kanren. They're called lists in the article and said "to group values or variables so that the collection may referred to as a unit", which sounds like a generic list to me. He compares them to Lisp lists just a couple paragraphs lower. Could you elaborate please?

These examples always end up being "we moved from MySQL to NoSQL" rather than "We moved from Sybase ASE to NoSQL"

That's because there's a zillion MySQL installs out there, with users that talk about them. On the contrary, there are a lot less Sybase installs out there and their (corporate) users don't talk about them. Go figure that you only hear about MySQL. But please, keep on spreading the FUD; that just gives us the edge of using a free, OSS, system.

DISCLAIMER: This is not a high-fidelity reproduction of Digg's situation

And it's probably not even a low-fidelity reproduction. The article gives us no reason to suppose he actually knew or understood the problem Digg had. He just shows that it was not a trivial one, as that would've been easy to solve.
There's been a few sites which brought this up..

On a totally unrelated note, anyone know if VOIP is working better on the nexus one's these days?

I think the parent author's main point is they used a defective RDBMS as a representative example of all.

MySQL does not do certain things well. However many mature RDBMS's have solved these problems and its worth pointing that out before you drop the entire class of tools for the next shiny tech.

25 Little Known Ways Everyday Technologies Are Affecting Your Health
Did you know that workers were hospitalized while making mobile phones? Additionally, did you realize that you are at increased risk of dying from surgery fire created by increased technology usage in hospitals?
Great point. The thing I'm interested in on these new data storage technologies is at the low level, rapid development, early stage (low traffic) portion of a project since thats where I'm at.

I'd rather be able to remove barriers like having to design a schema, and get some early efficiencies to develop my app fast and iterate.

Though, my experience in scaling every site that needed to be scaled has concluded with sharding. So MongoDB sort of fits there as well with its autosharding capabilities.
Is this company legit? Has anyone here ordered one?
Sounds like PR at best, bullshit at worst.

Sorry, but I don't buy it. Military encryption is designed to resist attacks done by enemy governmental agency.

They say thank you for all the $/CPU but lately I've read they were in dire need of cash to continue running the website, yet, they spent that money on cracking some alleged secret material...

Oh, and I'm pretty sure that cracking governmental material is considered an act of war, that would be pretty stupid to admit that publicly.

Sorry, but all of this sounds like kids living in a paranoid delirium or people trying to get attention (to raise money?).

ANU. I was talking about overall rankings. Not really sure how they calculate it.

> which is direct disregard for the law

The law which they didn't agree to abide by in the first place. Born into a country with a law you don't agree on enforced upon you, why should you stick to it if you both disagree with it and agree to take the consequences?

You seem to be arguing that it's bad simply because it's illegal, which is both circular (it's bad because it's bad), and annoyingly naive (respect authority for no other reason than it's authoritative).

> The ramifications of doing so with respect to hacking the encryption algorithm could possibly cause far greater damage that the release of the video itself

You have a better argument here, but one I disagree with - did you miss the last decade of XP security holes? Security by obscurity isn't a strong defense. If it's weak enough for ordinary people to break, the intelligence agencies of the world who care would make mincemeat of it.

> The point I'm really trying to make is that they are actively trying to acquire and release classified information, which is direct disregard for the law. If they were to "go away"

The hypocritical point you are trying to make is that you respect the law like a good citizen, and because they don't respect the law in the same way as you do that makes them scum who are unworthy of compassion, and as a result you'll happily become like them and disgregard your support for equality and human rights laws so they can suffer, while still feeling superior to them because you abide the law, while at the same time you are not doing so.

> What kind of society have we come to where it is revered to break the law in order to exact some change on our government?

What kind of society have we come to where people are unable to consider that 'law' and 'doing the right thing' might not the same thing?

By changing its position in the sentence, you alter the meaning of “sufficient” (this “sufficiently” and this “insufficiently” are not opposites), and the primary implications of the two sentences are thus not contrapositives.

Laches doesn't invalidate a patent; it simply allows you to defend yourself in the particular case you raise it in.

Laches is a form of estoppel, which is geared around the basic idea that if you do something I could sue you over, and you can show that:

1. I did something which gave you a reasonable belief that I wouldn't sue you, and

2. That was the only reason you went ahead and did it, then

3. I don't get to turn around and go after you, because it was really my actions which created the situation.

In a laches defense, you show that the person suing you for patent infringement knew you were doing or were going to do something which infringed, and deliberately waited to come forward with their claims so as to do the most possible damage to you. You argue that, had you known about their claims earlier, you would have done something different, and so it was their inaction which led to the current situation.

This doesn't stop the patent holder from going after other people, so long as they do it in a timely manner; the patent is still valid and can still be enforced. It also doesn't automatically stop future claims against you; it's expected, now that you're aware of their patent, that you'll work out some licensing deal to avoid future infringement. But it can throw out their current case against you, or at least throw out the massive back damages you'd owe from infringement over the period when the patent holder didn't bother doing anything.

The Co-Founder Matching Problem - 5 Articles on the Topic
It really depends on where your at, and honestly how pivotal you are to what the team is doing. As the boss, it would be nearly impossible for me to achieve this.

I do run a results-oriented shop. We have some guys who essentially work a 4 day work week (I have no idea how many hours they put in). They do try to make themselves available on fridays to answer questions or give quick input into problems we're having. Something like 5-15 minutes on an average Friday.

I, on the other hand, work a solid 5 day week. I do have a hard(ish) cap on my time at 8 hours every day however. I find that if I'm managing myself and my team properly that a 40 hour work week is plenty. Even at a boot-strapped startup like ours.
Don't miss the rainbow picture on page 3, it's a pretty cool hack:

"I then developed a far more nefarious test of color fringing: an algorithm that would take an arbitrary full-color image and generate a pure grayscale stipple pattern that appears colored on the N1 screen. The interesting thing about these images is if you display them at anything other than 100% zoom, the colors disappear and you only see the grayscale stipple pattern."
That's exactly how I feel, and so far I haven't read a single thing that would clear this things up for me. And I read pretty much everything about this topic that I get my hands on. I'm really egger to learn this stuff, to know where to use it, so I could use it in my projects where appropriate.
Somebody who truly gets NoSQL and has use it, should really really write something on this subject.
IANAL, but a quick googling turned up a couple of cases. http://www.patentlyo.com/patent/2008/10/laches-and-equi.html
http://www.patentlyo.com/patent/2008/08/inventorship-di.html

Apparently cases called Aukerman and Scimed established a precedent of 6 year for invoking a patent claim.
"[A] delay of more than six years after the omitted inventor knew or should have
known of the issuance of the patent will produce a rebuttable presumption of laches."
Key quote- "What's so exciting is that virtually any gene can be targeted now," he says. "Every protein now is druggable."
I have an iPod Touch and a Nexus One in front of me now. When looked at side by side, the Touch seems drab and fuzzy and the grid layout of the pixels stands out; while the N1 is crisp, and the white background of text is solid.

The thing it reminds me of most is a comparison between a CRT and an LCD. Apple seems to like applying more anti-aliasing to their fonts, certainly more than is customary on Windows, and it really shows on the Touch - whatever about the N1 having slightly fuzzy text when zoomed well out, the Touch's text is plainly fuzzy when zoomed to normal reading size.

Things other folks have brought up, like 18-bit with dithering vs 16-bit, I'm less concerned with. There's more contrast range in that 16 bits (by itself enough to make banding more obvious), while dithering doesn't strictly relate to the pixels displayed on screen and can be done in software. I expect updates can improve this.

The Cooliris Gallery browser the N1 ships with certainly does scale down photos before drawing them on screen; the browser is similar. This is annoying, especially if you want to zoom into a section on the photo, but again it's not related to the actual display. It looks more like an optimization designed to fit the image into a texture for hardware acceleration. Other photo gallery apps don't necessarily have the same implementation (e.g. B&B Gallery).

One actual aspect of the OLED display that does bother me somewhat is the way it "fizzes". When using the screen in the dark with the brightness at the lowest setting, all lit areas of the screen can be seen to be constantly flickering and alternating between different brightness levels at very high speed, a bit like the way the head of a freshly poured Coke's froth is constantly dissipating and getting renewed. But this is a very minor quibble.

As to contrast ratio with bright ambient light, I haven't found it to be a practical problem. I don't use my phone much outside during the day - even if I'm using the map, I'm more likely to be doing that in an evening - but even then, it seldom gets sunny enough in the UK to make the screen hard to read when it's at full brightness.
I dunno about the part about it being inborn or not though - I had been taking things apart for as long as I can remember, and the fact that I was 'different' didn't not bother me AT ALL - until puberty.
As a general rule, unless you're willing to shell out dollars and buy facebook ads (which many developers do), you need to really optimize your virals, especially the feed.

For more specific advice, what have you done for viral features? It would also help if you explained what your app is as well. Games work differently than say a quiz app.
Transaction Monitoring Enhancements
Monitis, the leading provider of 100% Cloud-based network and systems monitoring solutions, today announced significant enhancements to its transaction-monitoring tool, enabling important new features and reports.
Monitis’ suite of all-in-one internal and external monitoring tools, already the category standard for feature robustness and ease-of-use, is adding to its transaction monitoring capabilities with:
•	The ability to show all resources downloaded during the test flow using detailed information like DNS lookup time, first bite download time, and full-content download-time.<p>•	The ability to add transaction-step reporting for different periods and see the average time for each step to discover transaction flow bottlenecks.<p>•	The ability to monitor from a new European location – the Netherlands.<p>Hovhannes Avoyan, Monitis’ Founder and CEO, commented, “For e-commerce businesses across the Web, there is no better, all-in-one system than Monitis. Our transaction-monitoring continues to break new ground and innovate faster than the rest.”

Using guided demos in software prototyping
This is scarily misguided. Reminds me of an essay that a friend of a friend (who I do not know personally and would probably have long arguments with if I did) wrote about how Facebook was bringing us a better world because when your life is public you are forced to discover your "true self" as opposed to adapting your personality to whoever you communicate with. The devious man who happens to know both of us sent me that essay and sent him (the author of the essay) my essay about the evils of Facebook from the point of view of a non-user (http://everything2.com/title/Facebook+destroys+real+relation...) and then attempted to synthesize the two views, with what I consider insufficient success.

Sleep or Study?
I'm a college student. I always cram the night before an exam. Is it better to spend those extra few hours before the exam asleep or to use them to study more? On one hand sleeping allows you to be more alert during the exam but less prepared than if you had studied more. (I understand it's best not to put yourself in this position.)

The issues with getting the normals to use your apps, is that the generally won't search your product, neither listen or read about it because they don't read blogs, techcrunch, etc...

They end up using products when some friends tell them about it. You should focus on getting early adopters, without adding function that would fear normals. I think it makes sense. (I read that somewhere, but can't remember where - if someone had a link ? )
