Tilera preps many-cored Gx chips for March launch (link)

Upstart multicore RISC chip maker Tilera is timing the launch of its third generation of Tile processors to rain a little on Intel's forthcoming parade, and to try to blunt all of the excitement that is building for ARM-based alternatives for servers. Read more...

Howto: resize VirtualBox image

How would your resize VirtualBox image? The answer is simple:
Usage:

VBoxManage modifyhd         |
                            [--type normal|writethrough|immutable|shareable|
                                    readonly|multiattach]
                            [--autoreset on|off]
                            [--compact]
                            [--resize |--resizebyte ]


Example
C:\Program Files\Oracle\VirtualBox>VBoxManage.exe modifyhd YourImageFile.vdi --resize 20480
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

PUT or POST: The REST of the Story (link)

Web service designers have tried for some time now to correlate CRUD (Create, Retrieve, Update and Delete) semantics with the Representational State Transfer (REST) verbs defined by the HTTP specification–GET, PUT, POST, DELETE, HEAD, etc. So often, developers will try to correlate these two concepts–CRUD and REST–using a one-to-one mapping of verbs from the two spaces, like this:
  • Create = PUT
  • Retrieve = GET
  • Update = POST
  • Delete = DELETE

The free lunch is over now welcome to the hardware jungle (link)

The good news is that Moore’s “local scale-in” transistor mine isn’t empty yet; it appears the transistor bonanza will continue for about another decade, give or take a half decade or so, which should be long enough to exploit the lower-cost side of the Law to get us to parity between desktops and pocket tablets. The bad news is that we can clearly observe the diminishing returns as the transistors are decreasingly exploitable – with each new generation of processors, software developers have to work harder and the chips get more difficult to power. And with each new crank of the diminishing-returns wheel, there’s less time forimage hardware and software designers to come up with ways to overcome the next hurdle; the motherlode free lunch lasted 30 years, but the homogeneous multicore era lasted only about six years, and we are now already overlapping the next two eras of hetero-core and cloud-core.

Javascript Best Practices (link)

This document is a list of best practices and preferred ways of developing JavaScript code, based on opinions and experience from many developers in the JavaScript community. Since this is a list of recommendations rather than a list of absolute rules, experienced developers may have slightly differing opinions from those expressed below. Read more...

JavaScript on the server: Growing the Node.js Community (link)

While we all know and love JavaScript as a language for browser-based scripting, few remember that, early on, it was destined to be used as a server-side language as well. Only about a year after JavaScript’s original release in Netscape Navigator 2.0 (1995), Netscape released Netscape Enterprise Server 2.0: Read more...

Node.js case study: The Trello at Fog Creek

Building a Modern Web Stack for the Real-time Web (link)

The web is evolving. After a few years of iteration the WebSockets spec is finally here (RFC 6455), and as of late 2011 both Chrome and Firefox are SPDY capable. These additions are much more than just "enhancing AJAX", as we now have true real-time communication in the browser: stream multiplexing, flow control, framing, and significant latency and performance improvements. Now, we just need to drag our "back office" - our web frontends, app servers, and everything in between into this century to enable us to take advantage of these new capabilities. Read more...

Case study: How & why to build a consumer app with Node.js (link)

node.js GitHub API search repositories by keyword example

Not long time ago I started learning JavaScript and node.js. Today I found this node.js module called node-github. I had fun while played with it. And here it goes one little sniped for searching GitHub source repositories by keywords.

var GitHubApi = require('github').GitHubApi;

var github = new GitHubApi(true);
var repoApi = github.getRepoApi();

repoApi.search('node github', function(err, repos){
    if (repos){
        var i;
        for(i = 0; i < repos.length; i++){
            console.log(repos[i].name);
        }
    } else {
        console.log('Not found any repos!\n');
    }
});
How to run
  • download and install node.js from here
  • run 'npm install github' in your source directory
  • create new file 'example.js' and paste code sniped into it and save changes
  • run 'node example.js'
Output you should see the following output to console:
C:\code\node\npm-index>node scripts\example_github.js
The "sys" module is now called "util". It should have a similar interface.
get:  post
send GET request: /api/v2/json/repos/search/node%20github

node-github-receiver

Richard Stallman Was Right All Along (link)

Late last year, president Obama signed a law that makes it possible to indefinitely detain terrorist suspects without any form of trial or due process. Peaceful protesters in Occupy movements all over the world have been labelled as terrorists by the authorities. Initiatives like SOPA promote diligent monitoring of communication channels. Thirty years ago, when Richard Stallman launched the GNU project, and during the three decades that followed, his sometimes extreme views and peculiar antics were ridiculed and disregarded as paranoia - but here we are, 2012, and his once paranoid what-ifs have become reality.

The Coming War on General Purpose Computation By Cory Doctorow (link)

"As a member of the Walkman generation, I have made peace with the fact that I will require a hearing aid long before I die, and of course, it won't be a hearing aid, it will be a computer I put in my body, so when I get into a car - a computer I put my body into - with my hearing aid - a computer I put inside my body - I want to know that these technologies are not designed to keep secrets from me, and to prevent me from terminating processes on them that work against my interests."

Reducing Code Nesting (link)

"This guy’s code sucks!" It’s something we’ve all said or thought when we run into code we don’t like. Sometimes it’s because it’s buggy, sometimes it’s because it conforms to a style we don’t like, and sometimes it’s because it just feels wrong. Recently I found myself thinking this, and automatically jumping to the conclusion that the developer who wrote it was a novice. The code had a distinct property that I dislike: lots of nesting. But the more I think about it, the more I realized that it’s not really something I’ve heard discussed much. Read more on Reducing Code Nesting here...
