appscale -

Google Code: "AppScale is an open-source implementation of the Google AppEngine (GAE) cloud computing interface. AppScale enables execution of GAE applications on virtualized cluster systems. In particular, AppScale enables users to execute GAE applications using their own clusters with greater scalability and reliability than the GAE SDK provides. Moreover, AppScale executes automatically and transparently over cloud infrastructures such as the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) and Eucalyptus, the open-source implementation of the AWS interfaces"

Recreating the button | stopdesign

Recreating the button | stopdesign: "Until some future version of HTML gives us new native controls to use in a browser, at Google, we’ve been playing and experimenting with controls we call “custom buttons” in our apps (among other custom controls). These buttons just launched in Gmail yesterday, and they’ve been in Google Reader for two months now. The buttons are designed to look very similar to basic HTML input buttons. But they can handle multiple interactions with one basic design. The buttons we’re using are imageless, and they’re created entirely using HTML and CSS, plus some JavaScript to manage the behavior. They’re also easily skinnable with a few lines of CSS, which was a key factor now that Gmail has themes."

Paul Buchheit: Communicating with code

Paul Buchheit: Communicating with code

Some people can sell their ideas with a brilliant speech or a slick powerpoint presentation.

I can't.

Maybe that's why I'm skeptical of ideas that are sold via brilliant speeches and slick powerpoints. Or maybe it's because it's too easy to overlook the messy details, or to get caught up in details that seem very important, but aren't. I also get very bored by endless debate.

We did a lot of things wrong during the 2.5 years of pre-launch Gmail development, but one thing we did very right was to always have live code. The first version of Gmail was literally written in a day. It wasn't very impressive -- all I did was take the Google Groups (Usenet search) code (my previous project) and stuff my email into it -- but it was live and people could use it (to search my mail...). From that day until launch, every new feature went live immediately, and most new ideas were implemented as soon as possible. This resulted in a lot of churn -- we re-wrote the frontend about six times and the backend three times by launch -- but it meant that we had direct experience with all of the features. A lot of features seemed like great ideas, until we tried them. Other things seemed like they would be big problems or very confusing, but once they were in we forgot all about the theoretical problems.

The great thing about this process was that I didn't need to sell anyone on my ideas. I would just write the code, release the feature, and watch the response. Usually, everyone (including me) would end up hating whatever it was (especially my ideas), but we always learned something from the experience, and we were able to quickly move on to other ideas.

Google Bails On Print Ads (And Newspapers)

Google Bails On Print Ads (And Newspapers): "While we hoped that Print Ads would create a new revenue stream for newspapers and produce more relevant advertising for consumers, the product has not created the impact that we — or our partners — wanted. As a result, we will stop offering Print Ads on February 28. For advertisers who have campaigns already booked, we will place their ads through March 31."

Official Google Data APIs Blog: Bringing OpenID and OAuth Together

We are happy to announce an important enhancement to our recently launched OpenID endpoint. Google now supports the "Hybrid Protocol", combining OpenID federated login together with OAuth access authorization. Websites can now ask Google to sign-in a user using their Google Account, and at the same time request access to information available via OAuth-enabled APIs such as the Google Data APIs.

VSDB

VSDB: "VSDB is an experimental database based on atomic updates of constant databases. Unlike other lightweight databases, VSDB supports full transactional semantics when reading and writing to the database. A VSDB database consists of several hash tables (with plans for other data structures). Transaction conflicts are detected and rolled back and the system maintains full ACID semantics. VSDB may be used across distributed filesystems such as NFS without problems."

Finding The Memristor

IEEE Spectrum: How We Found the Missing Memristor: "Memristor is a contraction of “memory resistor,” because that is exactly its function: to remember its history. A memristor is a two-terminal device whose resistance depends on the magnitude and polarity of the voltage applied to it and the length of time that voltage has been applied. When you turn off the voltage, the memristor remembers its most recent resistance until the next time you turn it on, whether that happens a day later or a year later."

High on Evernote: Cloud Storage for Consumers

High on Evernote: Cloud Storage for Consumers

What is so great about Evernote?
Evernote covers all the bases of Cloud storage:

• It doesn’t care what kind of data you put in it, it supports any file type as well as raw text.
• It is storage online and an automatic backup of local files.
• It is available online and offline.
• It allows you to edit your from “within” the application (even files, when opened from the interface).
• It is a bookmarking system that allows you to organize all your data with tags and retrieve it via search or browsing.
• It keeps a full copy of any data you find interesting on the web that you can capture through a bookmarklet.
• It allows you to structure your data in a free form way, and keep meta data about the data with the data.
• It allows you to share your data with others, either in bulk (through public notebooks) or in batches (exporting notes).
• It is accessible from clients on platforms that people interact with almost constantly which makes it available to gather your created data from wherever you are and whatever format the data is in.
• It is extendable through it’s developer API so that third-party clients can be written against it to manipulate your data from even more platforms and combine it with other services that you already use to collect, create or modify data (with the ability to auto sync with those services).

This is the promise of the Cloud - being able to access and store any data you have from wherever you are whenever you want.

Anti-RDBMS: A list of distributed key-value stores | Richard Jones, Esq.

Anti-RDBMS: A list of distributed key-value stores | Richard Jones, Esq.: Perhaps you’re considering using a dedicated key-value or document store instead of a traditional relational database. Reasons for this might include:

1. You’re suffering from Cloud-computing Mania.
2. You need an excuse to ‘get your Erlang on’
3. You heard CouchDB was cool.
4. You hate MySQL, and although PostgreSQL is much better, it still doesn’t have decent replication. There’s no chance you’re buying Oracle licenses.
5. Your data is stored and retrieved mainly by primary key, without complex joins.
6. You have a non-trivial amount of data, and the thought of managing lots of RDBMS shards and replication failure scenarios gives you the fear.

Whatever your reasons, there are a lot of options to chose from.

about:cmlenz - CouchDB "Joins"

about:cmlenz - CouchDB "Joins": "Despite all that activity (and past experience with the conceptually similar Lotus Notes), the correct approach to designing applications “the CouchDB way” isn't always obvious to me at this point. Just today, there was a discussion on IRC how you'd go about modeling a simple blogging system with “post” and “comment” entities, where any blog post might have N comments. If you'd be using an SQL database, you'd obviously have two tables with foreign keys and you'd be using joins. (At least until you needed to add some denormalization.)

But what would the “obvious” approach in CouchDB look like?"

8 Definitive Web Font Stacks [Design Tips & Tricks]

8 Definitive Web Font Stacks [Design Tips & Tricks]

Over the last few months, I’ve spent more time than I intended on exploring the whole idea of fonts and typography for the Web. (My friend, typography expert Simon Pascal Klein, writes, “The former is a stylized set of glyphs of characters,” while “the other [is] the whole art of creating type and setting it into the written word.” For more clarification and illumination, consult Jon Tanand Mark Simonson.)

In the process, I’ve been considering the idea of font stacks—using the well-known font-family CSS property—to list as many different fonts as possible in order to optimize the web site experience for a maximum number of users.

...

As noted above, the general ordering is: the less widespread Windows fonts, then Mac fonts, then Linux varieties, then universal fonts, and finally, the generic family name.

Four Reasons to Love CouchDB, Part 2 | A.J. Brown's Blog

Four Reasons to Love CouchDB, Part 2 | A.J. Brown's Blog: 

"Reason #2: It’s not a RDBMS"

RDMS’s are powerful, but sometimes they’re overkill for our applications. I’ve seen some hypothesis suggesting that CouchDB’s document oriented strategy would work for 90% of web applications today. Who knows how accurate that is, but it definitely makes you think. After all, you can’t get any more cutting edge than a database engine asking us to rethink how we model data which is written in a language that asks us to rethink parallel processing.
