Trying out this Go thing...

Sat, 25 May 2013 02:32:25 -0400

Go was initially very attractive to us. The language felt very natural coming from Python backgrounds, and the performance approaches C levels. The goroutine model and channels are very easy to work and immensely powerful to manage concurrency.

Is This Google X's Plan to Wire the World? - Businessweek:

Google (GOOG) Chairman Eric Schmidt’s April 13 tweet was bold, ambitious, and a bit inexplicable. “For every person online, there are two that are not,” wrote the co-author of the book The New Digital Age. “By the end of the decade, everyone on Earth will be connected.”

The Daily Dot - The real origins of Tumblr:

Tumblr took the best of what Projectionist and anarchaia had to offer and combined it in one platform: anarchaia’s simplicity met Projectionist’s design appeal.

Only Spacetime - John A. Macken:

How many component parts are required to construct the universe? The standard model has so many component parts that it is difficult to state a specific number. String theory has vibrating strings, branes, exchange particles and 11 dimensions. This book makes the case that everything in the universe can be formed from the single building block of 4 dimensional spacetime. However, this is not the quiet, smoothly curving spacetime envisioned by Albert Einstein. Instead, it is the composite of Einstein’s spacetime and the quantum mechanical spacetime filled with a tremendous energy density of quantum fluctuations. This book shows how all fundamental particles, forces and cosmology can be derived from this energetic 4 dimensional spacetime.

7 Python Libraries you should know about

7 Python Libraries you should know about:

watchdog is a Python API and shell utilities to monitor file system events. This means you can watch some directory and define a “push-based” system. Watchdog supports all kinds of problems. A solid piece of engineering that does it much better than the 5 or so libraries I tried before finding out about it.

On the JVM: Java GC tuning for High Frequency Trading apps

On the JVM: Java GC tuning for High Frequency Trading apps:

In a nutshell heaptrasher is an application which is used to generate a lot of garbage to GC operate on. In addition it contains some code to generate histogram with latency statistics. Mentioned statistics data can be collected in two different ways. Worth mentioning is that the first one (array) allocate a lot of memory in Old Generation space and the second does not. I was later to find, it has a considerable impact on GC performance.

Cryptography: The solace of quantum | The Economist:

CRYPTOGRAPHY is an arms race between Alice and Bob, and Eve. These are the names cryptographers give to two people who are trying to communicate privily, and to a third who is trying to intercept and decrypt their conversation. Currently, Alice and Bob are ahead—just. But Eve is catching up. Alice and Bob are therefore looking for a whole new way of keeping things secret. And they may soon have one, courtesy of quantum mechanics.

Researchers forward quest for quantum computing:

Results of the team’s latest research, which shows that the unique properties of a TI can be modified by intrinsic defects present in Bi2Se3 films when grown on graphene/silicon carbide (SiC), were featured on the front cover of a recent issue of the journal Physical Review Letters.

Lessons Learned: A Year with a Large AngularJS Project - @jhooks:

I’m of the opinion now that Directives are the killer feature of AngularJS. They are wonderful little packages of contained UI/Presentation logic. They present so much flexibility and power with their ability to extend the grammar of HTML. We definitely use directives, but perhaps not as much as we could.

Open source Clustering software

Open source Clustering software:

The open source clustering software available here implement the most commonly used clustering methods for gene expression data analysis. The clustering methods can be used in several ways. Cluster 3.0 provides a Graphical User Interface to access to the clustering routines. It is available for Windows, Mac OS X, and Linux/Unix. Python users can access the clustering routines by using Pycluster, which is an extension module to Python. People that want to make use of the clustering algorithms in their own C, C , or Fortran programs can download the source code of the C Clustering Library.

The Go Programming Language Blog: Advanced Go Concurrency Patterns:

At Google I/O a year ago Rob Pike presented Go Concurrency Patterns, an introduction to Go’s concurrency model. Last week, at I/O 2013, Go team member Sameer Ajmani continued the story with Advanced Go Concurrency Patterns, an in-depth look at a real concurrent programming problem. The talk shows how to detect and avoid deadlocks and race conditions, and demonstrates the implementation of deadlines, cancellation, and more. For those who want to take their Go programming to the next level, this is a must-see.
