Yeah, there certainly are a few more tricks with regards to scaling RDBMS than the author covered. Depending on what your demands are there are different techniques and protocols which best suite you and can go very far to solving your problem. But with that in mind there may be better ways to solve your problem, and we should not forget about those.

If You start sharding you may get write gains, but you have to work very hard to keep things consistent (depending) and you may have to duplicate shards to make them highly available ($$$). Oh - and later down the track your schema might change in ways which your sharding scheme is just not flexible enough to deal with and depending on who you are that may be too much of a risk.

Besides the issue is really with availability, consistency and performance. It is very hard to scale all three of these together and even your cashcow solutions will hit their limits (although some of their limits are quite high :))
Does anyone else think that trusting Microsoft (or any other corporation/business for that matter) with a PROMISE is a bad idea?
You can push anything, server notification, facebook notification, twitter replies or push mail.. as it is based on Growl. Pretty clever!

Wrong. Longest lived groups in the USA are vegetarians. These vegetarians also rank on the longest lived groups in the world!

"For recent example why your theory of parity of exposure is not valid, see Microsoft vs. Alcatel-Lucent."

And what, pray tell, do you want me to take away from that?

My point is simply this: big companies know they can't avoid the possibility of patent trolls. The next best thing, then, is ensuring that your competitors in a given market are at least as screwed as you are if someone starts slinging lawsuits.

Having other people implement Theora first while they sit back and watch to see what happens gives Apple (and Nokia, which everybody still seems to forget) that position: if nobody sues immediately, they can choose to implement Theora and know they're no worse off than the competition. If somebody does sue immediately, they (Apple and Nokia) will just issue an "I told you so" and stay away from Theora.

Similarly, right now if somebody starts suing over submarine claims on H.264, Apple's not really any worse off than some of the other players.

This has nothing whatsoever to do with law or lawyers or courtrooms, and everything to do with managing risk.

He seems to distort Linux a little by focusing on Redhat derived distributions.

The guy is as close to an expert in this field as it gets right now. If he says lots of meat is bad, I tend to believe him. One day we'll know exactly how and why, but right now I trust him.

And a bit of speculation: lots of heavy metals accumulate up the food chain. If you eat an onion, that's one onion's worth of heavy metals extracted from the ground. But if you eat a chicken leg, it's a few kilograms worth of plant that accumulated in it. And when you feed them animal protein it concentrates even further. Over a lifetime it's probably a difference of an order of magnitude between a meat-eater and a vegetarian.

"Again, how do you know you have a talent for something unless you actually do it?"

You do a little of it, then compare yourself against statistical norms.

For instance, I have a talent at playing the piano. I took lessons for around 10 years. At the end, I was able to compete against other people who took the same amount of lessons and win a scholarship. Now -- I did not continue developing that talent, so compared to say, a concert pianist, I'm a complete musical idiot. I know enough to be dangerous. But of course, looking at some guy on the street playing the kazoo, he's the idiot compared to me, etc.

Same goes with languages. Usually there are standard ways of teaching language concepts. You apply the teaching for a small amount of time (say an hour or a few days) and then compare with statistical averages.

It's not foolproof, but it's more right than wrong. That's how statistics work.

This work-vs-talent equation works at all levels. I knew a guy who became a supervisor for around 30 employees. Smart guy, knew his stuff, but he couldn't spell. He, quite frankly, looked stupid compared to most of the people who worked for him. So he took the time and boned up on his spelling. He was no more stupid than I am -- smarter in a lot of ways -- but he just didn't see the point in emphasizing spelling until later in life.

You're always stupid compared to something else. The word "stupid" doesn't exist in a vacuum. There's always some subtext involved when you use it.
Thank you very much for being the only person in this sub-thread to attempt to source.
I've seen the term artificial scarcity used a few times in this context. Could you elaborate on what you mean by that?

When I think artifical scarcity, I think something like DeBeers who has warehouses full of diamonds they are hoarding. Whereas with software, there actually is a scarcity of great programmers. There are only so many of them.

With software, you know... it takes time and energy to support it. It costs money to write help documentation, pay for servers where people can download it. All that stuff costs money.

Is open source anti-capitalism?

Is the artificial scarcity coming from the thought that because software is just 1's and 0's that it can be copied almost infinitely? It takes a lot of time and energy to build something that is worth copying. What about all that research and development and risk that was taken to build it. How are those risk takers and R&D staffs going to generate a return on that investment without charging for the product they create?
Well, Safari supports it today including on the iPhone as of verison 3.0. If YouTube rolls out HTML5 support in the next six months, that covers what, a third of all the video on the web (on YouTube itself and embedded on blogs)?
I hate do do it (no, not really), but I told you so. :-)

Mono _is_ a patent minefield and trusting Microsoft not to sue based on a promise of good behaviour is ludicrously optimistic, at best.
Maybe... Are these sort of "promises" legally binding?
Like Microsoft being anti-anything-non-Microsoft?
A nice feature, but it's too bad there is not a full instance metaclass for precisely controlling how each instance is stored. Perl and Common Lisp have this.

People who tweet what they eat. I don't mind the occasional 'those berries were nice' but some people go over the top. The exception to this rule is if they post a picture (twitpic) with it. You could analyze "eat", "lunch", "dinner" keywords.

People who RT everything someone says. For example I follow several web designers and programmers as well as Nettuts. Nettuts just RTs everything the other people tweet. Very annoying.

As other people have mentioned #moonfruit and #squarespace. Very annoying when they do it every single day. (Mayby analyse frequent hashtags in a certain period of time?)

LOL. I fixed the chair before takeoff, so it was pre-alcohol. I was trying to work a MacGruber comment in there somehow though, so thanks for that.
Does anyone here know if their promise will cover future versions? Or if they can sue an implementation of an older version of ECMA 334 and 335 if they chose to extend it?

And how much ECMA standards are worth if Microsoft decides to extend them in their implementations? It seems to me whatever comes with the latest Visual Studio is the de-facto standard, not whatever ECMA publishes.

Server Side Form Validation using Regular Expressions
Some days back I had posted " Perfect Javascript Form Validation using RegularExpressions ", one of the reader commented like this "If I disable Javascript?". So in this post I given a simple example about "Server Side Form Validation using Regular Expressions ". Take a look at live demo.
It was a different era. Smart, diligent, well-meaning people, chosen through the best mechanisms of election and promotion available, did things we now understand were awful.

It's easy to judge from here and now, but in a similar position of responsibility, are you sure you would not make equivalent mistakes either way -- too much aggression, or too much passivity? WW2, Hitler, Stalin were still the kinds of threats on people's minds -- where less than 20 years earlier failure to engage and deter early had resulted in the death of tens of millions.

Communism loudly claimed it was the irresistible wave of the future and was showing the military power to make the claim credible. Soviet H-Bombs. A brutal and bloody stalemate in Korea. Tanks rolling into eastern Europe; Soviet satellites crashing into Wisconsin; nuclear missiles in Cuba!

And if it hadn't been Kennedy at the helm -- it would have been Nixon! And if not LBJ -- it would have been Barry "lob a [nuke] into the bathroom of the Kremlin" Goldwater!

We can chuckle at the "sorry" "mistakes" of the "domino-theorists" with as many "scare-quotes" as we like from our "comfortable" "decades-later" "safe" perspective, but the fact that there was a large consensus of smart, non-evil, "right-thinking" people behind most U.S. cold-war military actions should prompt a little humility in passing judgment.

Finally, peace requires some measure of forgiveness. To imply there's still some score to settle 40 years later -- some punishment McNamara (if he were alive) and peers still deserve -- is the attitude behind never-ending war and strife.

Remember when Microsoft promised an open document standard for the next Office -- and it was many thousands of pages that was less than trivial to implement?

(Without looking, I assume that to add maiming to injury, the standard allowed variations, so non-Microsoft documents could be made incompatible between versions of Office?)

I haven't played the game, but the idiom these days seems to be "the cake is a lie".
It's somewhat amusing that it's Apple holding out hardware implementations as the key when for years they've included chipsets in their desktops and laptops with decoding ability that they've simply not used.

This has now changed with Snow Leopard, but even then it's only one video card:

""While Apple has previously included graphics cards that have contained hardware support for H.264 decoding, the company has only recently taken advantage of this hardware acceleration. Mac OS X Snow Leopard's specs officially acknowledge this support but it appears to be limted to the NVIDIA 9400M graphics processors found in recent Apple laptops and desktops," Kim reports.

"Unfortunately, it does not appear that this support will extend to older video cards," Kim reports. "Hardware decoding of H.264 video improves the performance of video playback while leaving your computer's CPU free for other tasks."

If you prefer a desktop app for offline use (not just for privacy) then it can be done using something like Gears or Air. The app might save some or all notes locally and sync them when necessary. With a web app you can work from other computers/ platforms and mobile devices (android, iphone, netbooks). Don't you think that's important?
Arch Linux provides a hierarchy of build scripts that were used to build the binary packages you download using the standard package manager (pacman). Like BSD ports, the actual source is not contained, but each build script instead points to the source tarbal upstream. You can of course apply your own patches or change the sources the builds scripts uses.
The point of the lawsuit I referenced is to clearly demonstrate, that:

"Similarly, right now if somebody starts suing over submarine claims on H.264, Apple's not really any worse off than some of the other players."

is simply not true. Microsoft properly licensed MP3 format. So did other companies. Lucent sued only Microsoft and not other companies. Patent holders can pick and choose who, when and where they will be suing for infringement. There is no duty to sue all known infringements.
Safari supports HTML5 video element, but not HTML5 per se. It is not finished yet.

Interestingly, when YouTube supported only Sorenson, Apple didn't care for that and went on ignoring YouTube. Why it is suddenly a problem?
Can anyone give me the context? I don't believe in absolutes. I only believe in "it depends on the application/budget/knowledge/etc"
I used Gentoo as my main desktop OS for a year. The system will not get much faster because of the CFLAGS one uses (this is especially true for x86_64), but you can customize the packages you build to contain exactly the functionality you need (through the use of USE flags).

In the end, I switched over to Arch Linux (got tired of waiting for compiles), then switched to Debian testing (needed loads of LaTeX packages not found in Arch Linux), before I switched back to Arch a couple of weeks ago.

Oh, everything in moderation. But personally, I don't buy stuff from criminal monopolists.

In some situations, I assume I might buy from criminals -- but I avoid monopolists like the plague.

The problem with monopolists is that they have business reasons to not be compatible. That means they have to keep their systems so complex that they can't easily be cloned -- and also to be a bit incompatible between versions.

That damages my life quality, if I worked with their stuff.

That was a logical argument. After someone damaged my life quality, I will be pissed off. That is human nature.

Edit: The ending was too harsh, I do believe you didn't intend an ad hominem... you just think that it is meaningless to be upset about Microsoft. I hope you're right.

Here's a planning discussion from a few months ago on Fennec (aka Firefox Mobile) and it's support of the Video tag

http://archive.netbsd.se/?ml=mozilla-dev-planning&a=2009...

There's a summary post at the very end which says, Theora on portable hardware with DSP acceleration is very doable, and that they have a suitably qualified volunteer to do it.

"On performance:

* Right now we're getting 1-2fps with decoding video (wasn't sure what
size, though?)

* Some people on the call had done testing and it's possible to do
24fps at VGA resolution of Theora decoding, not including YUV -> RGB
conversion and without the painting overhead. This was on a 200mhz
ARM chip. So we know it can go fast.

* It's very possible to port that decoding code to a DSP chip -
someone did it at broadcom and was able to get 720p decoding at full
speed on a 125mhz DSP chip. So we know this is possible.

* In theory because of the design of Theora we should be able to do
better than H.264 in terms of performance and be able to match on
power consumption as well.
"

Here is a mail confirming that the work is underway:

Well, you're right in the sense that Newton was right about gravity. It works perfectly down here on earth, but breaks down out in the universe. In a distributed system you'll want to take into account caching, replication, atomicity, security, etc. In other words, that's either going to be a hell of a complex API or an API that gives you too little control to build a high-performance system. There's no telling what works best, every computer system is a set of trade-offs and it always depends on the application.
I'm the author of Redis so I should be biased the other way around, but the Redis and KV experience taught me that to be exposed to the KV parading was for me a similar experience as learning the Scheme language, I started to write code in imperative languages in a new way. In the same way once you start thinking at scalability of your data in a new way, from the point of view of partitioning the data, organizing this data in away that is easy to access for your usage pattern, make judicious use of serialization, SQL databases can be a good pick. Simply you need to abandon the paradigm of let's design our nice tables and run our multiple joins and group by against.

But of course designing DBs in this new way makes most of the SQL features not needed in most scenarios... and you still have the overhead. And there are a number of other limits now that complex designs are not a good idea, for instance there is no way to get back the data in the natural ordering (the order you pushed this data, or the reverse)...

This is where KV stores start to be interesting as real world alternative, not just in order to learn the paradigm of scalability. But again, if you don't trust KV stores it is truly possible to use an SQL database in a more conservative and scalable way.
Microsoft takes Gazelle secure browser on road trip
"Patent holders can pick and choose who, when and where they will be suing for infringement."

But if you're the only company implementing the infringing technology, the risk is entirely yours. If lots of companies implement it, it's more of a game of Russian roulette; maybe they pick you, maybe not.

And historically, patent trolls don't seem to be quite so picky, and they're the ones to worry about. The Lucent suit demonstrates why it's so rare for bigger players to sue each other -- you end up with $BIGNUM suits and countersuits seeking damages which exceed the GDP of Switzerland, and that's not good for anyone involved.
The open source community needs more writing like this: conversational but not dumbed-down, informative but not dense. This was aimed directly at my level of familiarity, and hit it straight on.

Did you really expect the document standard to be 10 (or even 100) pages long and trivial to implement?

How long is the full spec for HTML, or PDF? Are either of those "trivial" to implement? Both of those formats are, IMNSHO, inherently simpler than the sum total of complexity of all the Office document formats. (Even if you just include Word and Excel)

Microsoft can't win here. Either they document the simple middle-of-the-road, 90% of Word docs conform, case, and get skewered for not being open enough. Or they release the full spec and get skewered for "Wow, writing a competitor to the most common word processing and spreadsheet application is actually harder than creating hotornot or million-dollar-homepage."
That's a very curious statement, especially for HN. Why would you consider needing good, experienced people to be a disadvantage?
A competing standard, which didn't have to do dirty tricks to get ISO certified, was a fraction (tenth?) of the size.
