"This is first of the three blog posts talking about how we build scalable, feature-rich, front-end apps for LinkedIn with an emphasis on site speed, performance, and developer productivity. Today, we'll tell you about our move from server-side templates, such as JSPs, ERBs, and GSPs, to client-side JavaScript templates powered by dust.js." - imabonehead from Bookmarklet

"It turns out that there are many client-side templating solutions to choose from. Some are based on Resig's microtemplating (e.g. underscore.js), some are logic-less (e.g. mustache), some use a Haml syntax (e.g. Jade), and some are Java friendly (e.g. Google Closure). All told, we evaluated 26 different templating technologies, scoring them on a variety of factors: DRY, JS library... more... - imabonehead

Mongo veritabanı üzerinde tasarımını tıpkı sql veritabanı tasarımı gibi yapıyorsun. Bu da sana bir kolaylık sağlamak yerine koca bir yük getirir. Mongoda (örn:) Post.Owner gibi bişey yapacaksan Post tablosu ve owner tablosu yapmak yerine Post{ prop1, prop2, Owner{ propx,propy}} şeklinde entity tasarladığın için foreign, primary vb key ilişkileriyle değil entity yi doğrudan yekpare tasarlayarak ilerliyorsun. En azından tavsiyeler bu yönde. - AdemC

"Netflix has been rolling out the Apache Cassandra NoSQL data store for production use over the last six months. As part of our benchmarking we recently decided to run a test designed to validate our tooling and automation scalability as well as the performance characteristics of Cassandra. Adrian presented these results at the High Performance Transaction Systems workshop last week." - imabonehead from Bookmarklet

"With more than 25 photos & 90 likes every second, we store a lot of data here at Instagram. To make sure all of our important data fits into memory and is available quickly for our users, we’ve begun to shard our data—in other words, place the data in many smaller buckets, each holding a part of the data." - imabonehead from Bookmarklet

"Our application servers run Django with PostgreSQL as our back-end database. Our first question after deciding to shard out our data was whether PostgreSQL should remain our primary data-store, or whether we should switch to something else. We evaluated a few different NoSQL solutions, but ultimately decided that the solution that best suited our needs would be to shard our data across a set of PostgreSQL servers." - imabonehead

"Wackamole is an application which manages a bunch of IPs which should be accessible from outside all the time. Given a set of machines and a IPs, wackamole will ensure that if any machine goes down, other machine will take up its IP almost instantly and outside world will see no impact. It tries to balance the number of IPs across the number of machines available. Wackamole uses Spread network messaging system." - imabonehead from Bookmarklet

"Graylog2 is an open source log management solution that stores your logs in MongoDB. It consists of a server written in Java that accepts your syslog messages via TCP, UDP or AMQP and stores it in the database. The second part is a web interface that allows you to manage the log messages from your web browser. Take a look at the screenshots or the latest release info page to get a feeling of what you can do with Graylog2." - imabonehead from Bookmarklet

"Hazelcast and GridGain are the best choice for an easily-parallelized, low-data, CPU-intensive tasks. Moreover, they are even better choice, when some unexpected node failures can happen." - İnanç Gümüş

Deferred Deletes is a technique where deleted items are marked as deleted but not garbage collected until some days or preferably weeks later. James Hamilton talks describes this strategy in his classic On Designing and Deploying Internet-Scale Services: Never delete anything. Just mark it deleted. When new data comes in, record the requests on the way. Keep a rolling two week (or more) history of all changes to help recover from software or administrative errors. If someone makes a mistake ...

This is a guest a post by Alvaro Videla describing their architecture for Poppen.de, a popular German dating site. This site is very much NSFW, so be careful before clicking on the link. What I found most interesting is how they manage to sucessfully blend a little of the old with a little of the new, using technologies like Nginx, MySQL, CouchDB, and Erlang, Memcached, RabbitMQ, PHP, Graphite, Red5, and Tsung. What is Poppen.de? Poppen.de (NSFW) is the top dating ...

The 2009 presidential election was the most closely monitored election in US history, thanks in part to the efforts of tech entrepreneurs like David Troy. Troy speaks at the 2009 Emerging Communications Conference about how he and his teams were able to create the Twitter Vote Report, which allowed people to report on poll conditions, and the Inauguration Report 09, a first hand documentation of peoples experiences at the 2009 presidential election.

If you were pestered with a dozen or more phone calls a day from people in your locality asking what was on your menu for the day, or inquiring about the delivery of their order, and you were definitely not the local Thai Kitchen but just an innocent guy or gal, what would you do? Well, youd listen to Danny Sullivan in this program. Danny discusses why local search is such a difficult task, and what some of the major ...

PowerPivot, a new add-in for Excel, can absorb and analyze vast quantities of data. And it can ingest that data from sources that support that Atom-based OData protocol. John Hancock, who led the charge to create PowerPivot, tells host Jon Udell how it works, why it supports OData, and what this will mean not only for corporate business intelligence but also for the analysis of open public data.

Some pundits have declared the iPad a “toy”, or suited only for content consumption. I disagreed with the latter a few days ago, and I think it will have some very interesting business uses. If I come up with a sufficiently novel one, Oasis Digital might implement it. But sadly I must mostly agree, for at [...]

Like 300,000 other people, I have a shiny new iPad in hand. Here is my very short review: Apple is going to sell a huge pile of these things. Expanding on that Lots of other companies are going to sell an enormous pile of apps for the iPad. From the point of view of a maker of software, [...]

In A Brief History of the Internet it was revealed that the Internet was based on the idea that there would be multiple independent networks of rather arbitrary design. The Internet as we now know it embodies a key underlying technical idea, namely that of open architecture networking. In this approach, the choice of any individual network technology was not dictated by a particular network architecture but rather could be selected freely by a provider and made to interwork with ...

In this presentation from eComm 2009, LiMos Open Source Committee Chairman, David Lefty Schlesinger discusses the meaning of governance, and the advantage of LiMos approach over those of Google and Apple for their Android and iPhone application development platforms, before opening the floor to questions.

Today Amazon Web Services takes another big step in making it easier to migrate legacy storage systems to the cloud through AWS Import/Export support for ingesting Punch Cards. AWS Import/Export accelerates moving large amounts of data into and out of AWS using portable storage media for transport. Punch cards are paper-based storage media that represent data using the presence or absence of holes in specific positions. With AWS Import/Export for Punch Cards, enterprises can begin using the service to preserve ...
