One of the great things about Linux, OS X, and other operating systems that are UNIX based is that you can use a lot of the same command prompt commands to do a lot of interesting stuff. Here are 10 of the most useful commands that you can use whether you're in a Linux terminal, OS X terminal, etc. Most of them will work straight out of the box, but some like apt-get, yum, etc. will only work with specific distributions or add-ons for operating systems that don't normally support the command.

The Transfluent API for Apps is the world’s first professional language translation service that can be embedded directly into the application build process. This means that every time the developer makes changes to the application, all of the different language versions also get updated at the same time.

Mobile applications are a truly global market, and localizing an application typically increases sales significantly. Despite the growing need for app localization, there has not been an efficient method of translating the apps into multiple languages until now.

The Transfluent API makes it possible to develop applications directly in multiple languages (as opposed to translating once the development has been completed). This shortens the time-to-market, increases the quality of the localized versions and lowers the cost of maintaining the multiple language versions.

Transfluent’s backend is powered by a network of more than 15,000 professional translators in over 60 languages. Each translation task is assigned to two independent translators – one does the translation and another proofreads the text. The API helps the developer specify context for the translation task, including screenshots taken from the application.

“For the best results, we recommend starting the translation process early on in the development of the app. Developing the app and testing it in multiple languages throughout the process guarantees that the localized versions work and feel as native as the original. Loyal users who are native speakers of various languages can be a great resource in making sure all the terminology is spot-on!” comments Jani Penttinen, founder and CEO of Transfluent.

Transfluent keeps track of the previous translations so that only changes and additions are translated. If required, the text can be sent to translation dozens of times a day, but translation will only performed where needed.

Transfluent has quickly become a trusted partner for prominent application developers, such as DocScanner developer Haave Inc., Recoil, NonStop Games and Kapu Toys.

Tommy Incrosnatu, CEO of Kapu Toys commented on Transfluent: "Kapu Toys is developing new kinds of mobile games for children. Transfluent has supplied us with comprehensive translation solutions which have helped us in production and marketing. Our co-operation with Transfluent has worked well; the service is quick and knowledgeable. Now, with the new API, updating new translation versions is even easier and more trouble-free."

Today Transfluent also published a white paper, detailing the typical problems and suggested solutions when localizing mobile applications. The white paper can be downloaded from Transfluent for Apps website in English, Spanish, Chinese and Japanese.
