The C in ACID is consistent, not serializable (i.e. it's not ASID). Consistency means that declared consistency constraints are enforce -- no dirty writes, no violations of unique indexes, referential integrity, and anything else that the bells and whistles supports.

Let me give a simpler example: Database with one table of one field, a number. One transaction: count the number of records and store that number.

A serializable system will force one zero, one one, one two, etc. But a consistent system can have two zeros and no ones. Why? Because that's what each concurrent transaction saw? Nothing wrong with that. But if application semantics dictate that each value must be distinct, then put a unique index on the number and the system will enforce uniqueness. Automatically enforcing "auto-magic" constraints that nobody cares about is why serializability destroys scalability of distributed system.

In NuoDB all messaging is asynchronous and batched, making it very fast and efficient.

Good point. I'd agree that the real innovation in both the iPhone and iPad was touch. It seems obvious now that touch is a completely different experience from the stylus, but it wasn't obvious enough that anybody else made the big investment to make it work, before Jobs.
I have strong knowledge and some good experience with MongoDB, and now, on my new job, we will use Riak (it's a new project that just starts) as primary server. And while user-friendliness of it is a bit horrifying sometimes (hope I can help to change that) in comparision to MongoDB, Riak's real beauty is it's architecture and main ideas.

And yes, these are just different databases. MongoDB is much more RDBMS-like (in terms of consistency, B-Tree indexes and queries), while Riak is what you think of when you think "auto-scalable". So now I love them both :-)

I couldn't tell if you were being sarcastic since you didn't offer any explanation, but it is true and wuster is wrong.

Hoarders/speculators help by smoothing the scarcity and resulting price increases over time. By buying things up early, they increase the price and scarcity early, which gets people motivated to switch to alternatives when they can (and warns people who weren't paying attention to whatever caused the shortage, the floods in this case, of the problem). When they resell later, their stock keeps the shortage and price increases from being as extreme as they would otherwise get without the hoarders.
I love the design! I especially like that the Now Playing functionality is so prominent. While I like iTunes as a media database and sync tool, it's bloat-tastic as a music player, and I've wanted something faster and cleaner for years now.

I have a question, though: Does this perpetually read or write from the iTunes library XML, or is the import a one-time affair? I use the hell out of ratings and smart playlists, and I want Enqueue to run side-by-side with iTunes rather than replacing it. (i.e., iTunes to manage music, Enqueue to play it back.)

Regardless, this is fantastic work, and I look forward to the finished version. This app is something I would definitely be happy to pay for.
Perhaps, that stems from the fact that Java's starter package implementation was the earliest to be developed and is still today the most mature (besides Python's anyway).
That's an interesting idea. We could offer that as an option: "Convert this text to an image".
There are definitely problems with RFID tags, but I think QR codes are even worse. That's why I say it's a stopgap -- maybe RFID fixes its issues, or maybe something completely better comes out, but I don't see QR codes being around 10 years from now (outside of business applications at least).

I'll have to check out i-nigma's app, but this isn't going mainstream until it's integrated into the phone. I believe Android already does (Google Goggles?), but get iPhone on board and we will definitely see the market turn.

I think designer QR codes look better, but this is an issue of putting lipstick on a pig -- it looks better, but not that much better.

I am helping a friend learn to program. He was doing "Learn Python The Hard Way" but was loosing steam. I created a project for him to do, a simple ASCII game: https://github.com/antoinehersen/ASCII-Dungeon-of-DOOM.
Having a project with visual and interactive elements is far more motivating. Also it push you to learn the real skills needed for programing, not only knowing what a loop is or how to open a file, but figuring what to use when, and how to organize and connect it all.
This experience will create a reference frame for everything he might subsequently read in a book.

I strongly believe that accomplishing a small scale project that as some value is the best way to learn.

The real estate signs made sense to me, because if you're interested you'd probably snap a photo of the sign anyway to remember the address and agent. But I don't get why you'd make your customers scan a code in your store -- they're already IN YOUR STORE.

It's pretty easy to demonstrate data loss with MongoDB if you're doing replication, but it's the "normal" behaviour because MongoDB uses asynchronous replication and W=1 writes by default.

Set up a n=3 cluster and a client that writes data continously, like:

i = 0; while (true) { write(_id:i, data:i); getlastresult(); /* to make sure the client sends it */ printf(i); i++; }

Now kill the master. Another node will become the new master. Issue some more writes to make sure the logs of the new and the old master diverge. Now bring back the old master, which will become a secondary, and it will say something along the lines of "finding common oplog point", and it will discard the writes that it had that were not copied to the other nodes before it was killed.

You can verify all this by looking at the i's that were acknowledged by the old master and printed by the client. The last couple of them will be gone for good.

If this is unacceptable to you, then you can run MongoDB with W=majority mode, but with MongoDB W>=2 modes (so-called consistent replication modes) are very slow.
Nice idea. Seems like a no-brainer for one of the "More Options".

I think the idea is to find out more about a product. Some people research a product before they get to the store, but some people don't. That's especially true for impulse buys.

I see the value of QR Codes in stores as being a way to quickly give you more information about a product.

IPhone 4S: Speck PixelSkin Case is Solid
How did they break it? If you don't install ruby from apt, you won't get the debian version of ruby or rubygems, and nothing is broken.

Is it reasonable to expect the apt version of ruby + rubygems to play nicely with an arbitrary compiled version that is installed in PATH? It would be nice, but few packages work this way.
I think the top question in your FAQ should be "Why should I use this over iTunes?" Then clearly state what you do better (such as file support, interface, etc).
I don't consider this as "reading tea leaves":

Despite the bullish talk about levels of engagement on Google Plus, I continue to find it strange that Google won't tell us how many of the reported 40+ million users are active, daily users.

Frustrated at not getting a straight answer to that, I optimistically asked Gundotra if he would at least give me the percentage of active daily users to total. But he wouldn't be drawn into that question either.

So I asked: what kinds of things are people doing on Google Plus right now? Vic Gundotra pointed to photo sharing.

"Since we went to field trial on June 28," he remarked, "we've had 3.4 billion photos uploaded to Google Plus."

http://www.readwriteweb.com/archives/google_plus_engagement....

"I sincerely doubt the service will die in a "year, tops" with 40 million users"

Naive much? That translates to we have 40M rows in a database table, please be impressed and don't ask us for engagement.
We don't have an API yet, but we will soon.
IIRC, people got upset with Google Profiles that your Gmail address was exposed from the URL (eg. profiles.google.com/dave would lead to dave@gmail.com). The URLs are thus anonymized to stop that leakage.

Fist impressions can never be reproduced, so I'm typing this as I go along:

1) Welcome dialog is... out of place. The design is not consistent with Apple UI guidelines, I can't tell the three options are buttons.

2) The cancel button on the welcome dialog looks like an odd man out. It's just floating there in the center, and I think the caption (cancel) is also something you can improve.

3) I think the now-playing thing in the sidebar needs to be pushed down by ~60 pixels, basically starting under the main bar across the rest of the screen. It's not very symmetric the way it is now. You should also have a divider between the close buttons and the now playing section - see Chrome.app for a good example of doing it smoothly.

4) Playlists: now change when I hover over the entries, I was expecting them to go blue. Clicking on them has no effect, I must double-click. non-intuitive.

5) I love the statistics and charts in History, but I wonder if the name is accurate? I'm seeing a breakdown of my music collection, but the only "true" history tab is "Recently Played" which is also given the least prominence.

6) When starting the app, the whitespace stretching from under the now playing section to the bottom of the screen in the sidebar is jarring. It doesn't look nice empty, I'm assuming something will show up there at some point in my playing around with it.

7) Playlists uses an entirely different UI from Library. I like Library's detail view drilldown. I think something like that should be used for the playlists too. See point #4.

That's all for now. May update later with more feedback.

Good work. It looks very promising. I love that it's fast and not-bloated.

EDIT:

No way to turn off Growl messages? Oops.

EDIT:

Add Playlist -> then press esc. The playlist gets added anyway with the default name.

Playlist list needs right-click functionality, even if it's the same menu that shows up when clicking the cog. Don't disappoint your users expectations as to how an interface will act.

EDIT:

Playlist tab's "Add Playlist" pretends to be a tab but it's actually a button. Very confusing. Don't do that - buttons are buttons, tabs are tabs. Even if they're right-aligned.

EDIT:

I think you have a bug when you turn on repeat and shuffle in the middle of a song. When the song ends, it will be repeated immediately, then everything works out.
Yes, difference in ease of use is certainly there and not ignorable. But wouldn't the need to send URL and pass-phrase via two different channels would be rather difficult to communicate to 'grandfathers'? Not an impossible task but, as someone who built consumer security products in the past, it's not ignorable either.
The "Innovator's Dilemma" describes the common scenario where the successor to an incumbent product is, when it's introduce, inferior to the incumbent on important axes; for instance, it could have inadequate storage, or be too slow, or not be secure. But the new product has attributes that make it way more attractive to some new market; for instance, maybe it's game-changingly cheap, or portable.

As a result, the new product won't be adopted by the core market for the incumbent product. It's used by a different market, or at the margins.

The "dilemma" here is, over the long term, the new product improves as it captures more and more market share. The new product has room to evolve and isn't locked into a core market with fixed expectations. Eventually, the benefits of the new product exceed those of the incumbent product, even for the incumbent's core market, and the incumbent product loses.

This all plays out in slow motion, so that even if the incumbent sees this happening, they can't do much, because they're dependent on the revenue from their core market.

Put fossil fuel in the "incumbent" box, "solar" in the "new product" box, "the industrialized west" in the "core market" box, and "the developing world" in "the new market" box.

You raise some great usecases. We have an option to require a password to view the secret but that doesn't directly solve the cases you bring up.

We're considering changing the basic UX to require a click to display the secret (the click will send a POST to retreive the contents). That will include a much more visible disclaimer that it's only available one time.

Data shouldn't change on a GET for these very reasons.

Therefore, the secret shouldn't be obtained from a GET, but rather a POST. A button or jQuery.post on the 'shared' page, for example, that fetches and causes the deletion.

I like this idea though.

I agree that people don't think to themselves, "how can I show Google that I love them," but I think behavior on the Internet thus far would show that they do want to feel a connection to companies. Millions of Facebook fans and Twitter followers can't be wrong. Even if they only get you to fan/like/follow/add-to-circle for a deal, it creates that relationship, and it's a real person pushing the button.

I had a flashback to one of the coolest video games of the early 90s PC era, Aladdin based on the Disney movie. In place of a conventional "life bar", in the upper left corner there was an image of Genie, whose expression would change from happy to concerned to terrified as you lost health. I always thought that was innovative. At a glance -- in less time than it took for your eye to measure the actual length of a health bar and compare it to its potential full length -- you knew with remarkable precision how much more punishment you could take before dying.

AFAICT, most recruiters are essentially independent matchmakers. That is, they aren't working for the employer and they aren't working for the employee: they're trying to reach out in both directions and bring people together.

The incentive is to cut in on a share of the new employee's income. OK, book agents and talent agents do that too. The difference is that those agents have a contract with the employee. It is in their interests to take on exactly as much work as they can handle, and to do a good job on each transaction. They're looking for repeat business in both directions -- getting jobs for their clients, and addressing the needs of employers.

Recruiters, on the other hand, don't have a contractual relationship with the talent. They have no incentive to do a good job for any given prospective employee, and little or no hope of repeat business.

Meanwhile, the same network technologies that let you tell everyone what you had for lunch today and let you look up the difference between "deciduas" and "deciduous" in half a second will let you put your resume up and tell all your friends that you're looking for a new job.

Facebook and Google+ don't have employment features yet, but it's more or less certain that they'll be after LinkedIn's lunch in the next year or so.
