Dynamic Methods in Static-Typed Languages

One of the great benefits of dynamic-typed languages is that they are able to add functionality to an object on run-time. For example, you can create an object and then add functions to it, giving it the desired behavior, without a complex inheritance structure. Moreover, when calling the object’s methods, the client can determine whether the object supports a certain operation or not.

Static-typed languages do not come with this advantage. Creating objects that share some behavior can be done by inheritance, yet this restricts the combinations of behaviors an object can have (unless it relies on multiple-inheritance, which has some tricky effects).

Browsers. The Final Threshold

Have you ever wondered about the purpose of browsers? And why are there so many of them, when they all seem to do the same thing?

Browsers are actually an essential part of the Internet. Without them, the whole world wide web would be meaningless. They are the entities that interface the work of web developers with the user experience. This is why browsers are so important.

App Testing Is Fun

The Apps Team is growing! We are on the look-out for talented software developers with a passion for research and automation testing to join our team in Bucharest.

Many people associate the software testing process with the image of a robot clicking on different links in an attempt to spot issues. Can’t really blame them, as in some cases this is quite necessary. Still, generally speaking, software testing is anything but trivial. As a matter of fact, software testing is software development, with the difference that the output is a software product that tests another software product. On many occasions, developing such a product turns out to be more creative than developing the software that has to be tested.

Johnny Wants To Go Home

Johnny is drunk homesick. After having spent the past years on the Island of Despair, he has suddenly decided to sail home. For this, he managed to build a boat. During his sailing, he discovered that the boat is small and cannot withstand a storm. As if it wasn’t enough, Johnny drank too much rum and is afraid of getting lost. Definitely, not a good day for sailing.

Technical Support Expert Wanted, Better Than 007

4PSA is expanding the technical support team for its flagship product, VoipNow. If you’re up for interesting challenges, this is your best shot at it.

The title is an intended pun, of course :). Still, it’s not that far from the truth, because as a Technical Support Expert, you are going to perform lots of investigations. Some complex scenarios may take hours or even days to complete. It’s not so much about the technical challenge, but mostly about making the customer happy.

HP Moonshot 1500 And The ARM-On-Server Madness

There is no apparent connection between these two, but Moonshot is actually in the same trend, even though it uses Intel x86 (Atom). Many people advocate for ARM on servers, mainly because it is low-power, allowing a high CPU count per rack. But no one would mind I guess with a low-power CPU from Intel either.

Unfortunately, not many have a good overall picture on the cloud challenges, not to mention software engineering. And this is pretty complicated.
