  A Quick Look at the Services Offered by RDBMs vs. NoSQL

The world of IT has to deal with the issue of data storage. The reason for this is that there is plenty of data produced and created daily on the internet and on various business applications. In the past, RDBMs or Relational Database Management Systems were used for storage. Even though they are still used today, there are other offerings that present competition and anyone wishing to purchase data storage systems needs to make comparisons.  One such competing system is NoSQL or Not Only ...

  Using public key authentication in SSH

SSH is a popular cryptographic network protocol for secure network service operation. It is frequently used in remote server login. For a system administrator or software developer, SSH is frequently used to access remote servers or development servers or testing servers etc.  To login with SSH, there are different authentication mechanisms : password, public key and interactive etc. If a remote server needs to be accessed frequently, password authentication may be too troublesome as p...

  Why I love everything you hate about Java

If you’re one of those hipster programmers who loves Clojure, Ruby, Scala, Erlang, or whatever, you probably deeply loathe Java and all of its giant configuration files and bloated APIs of AbstractFactoryFactoryInterfaces. I used to hate all that stuff too. But you know what? After working for all these months on these huge pieces of Twitter infrastructure I’ve started to love the AbstractFactoryFactories. Let me explain why. Consider this little Scala program. It uses â€...

  Cross Browser HTML5 Drag and Drop

HTML5 Drag and Drop has been talked about a lot lately, but it’s hard to find really useful information about implementing it across multiple browsers.Mozilla, Apple and Microsoft all have pages describing how to use it, but their examples seem to work only in their particular browser (Apple’s example doesn’t even work in their own! Updated, Jan. 11, 2009: Although I have not been able to get this example working on Safari 2.0.4 and 3....

  Difference Engine: Luddite legacy

AN APOCRYPHAL tale is told about Henry Ford II showing Walter Reuther, the veteran leader of the United Automobile Workers, around a newly automated car plant. “Walter, how are you going to get those robots to pay your union dues,” gibed the boss of Ford Motor Company. Without skipping a beat, Reuther replied, “Henry, how are you going to get them to buy your cars?”Whether the exchange was true or not is irrelevant. The point was that any increase in productivity required...

  How the Internet is Changing Economics

I'm not an economist by training, but I've spent a long time observing markets, and I've often wondered what the great economic thinkers of centuries past (Marx, Smith, Keynes, others) would say if they were alive today and could witness the transformations that have been caused by mass media (radio, TV, print) and the Internet. The Internet, in particular, has had a transformative effect that will doubtless be studied for hundreds of years to come. One of the things that can be said abou...

  Dates in PHP and MySQL

I see a lot of people on forums and on my training courses asking about the best way (or any way) to manage dates stored in a MySQL database and used in PHP. Three options follow, but first the problem.PHP uses unix timestamps for all its date functionality. It has methods to convert these timestamps into pretty much any text format you could want but internally it uses the timestamp format. A timestamp is simply an integer. Specifically, it’s the number of seconds that have ela...

  The Death of .NET and the Power of Perception

One of my long-standing issues with Microsoft is its inability to control the perceptions surrounding its own products. One of the biggest examples was during the Windows Vista years when, even after the product had been fully patched and worked fine, Apple continued to do a better job to define the image of Windows (compilation of ads here) than Microsoft did, costing Microsoft billions in lost revenue for the millions it saved on a strong advertising campaign. The firm has a history of being p...

  Google engineer: What I learned in the war

Veteran's Day is an ideal time to hear from one of those rare folks who combine corporate and military careers. Dan Cross, a software engineer at Google (GOOG) and a 1st Lieutenant in the U.S. Marine Corps, took a leave to serve active duty in Afghanistan, came home a year ago, and brought back lessons that he couldn't have learned in business. While he had never seen himself as the military type until a personal tragedy made him reroute his career, he's a better man for it. Cross, 34, is now an...

  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...
