      We are excited to announce our May Technical Talk. This time let's talk about Background Services in the browser!
      Agenda
      Time (UTC) Time (PDT) Topic 6:00 PM GMT+1 10:00 AM Welcome, Latest Samsung Internet News 6:20 PM GMT+1 10:20 AM Background Services in browsers by Maxim Salnikov, Microsoft 7: 00 PM GMT+1 11:00 AM Q&A Background Services in Browsers
      Is there an app life after closing a tab?
      The user closes the tab in the browser, and your wonderful front-end application evaporates. But, what if you could leave some parts of it to work a little more for the benefit of improving UX? To respond to some events, to complete the started communication with the network, in general - to execute some code with the tab closed and even the browser.
      We'll discuss interesting features of the APIs from the service workers family. Service Workers allow you to extend the life of the application so that you always have fresh data at hand, not be afraid of network problems, and be able to show notifications - all for the sake of a great user experience.

      Samsung has annnounced novel third-party compatiblity with TVs as part of its 2019 Developer Conference (SDC). This also involves the roll-out of new tools, so as to help developers generate fresh apps for this ecosystem. Therefore, more obsolete or perhaps less-used smart screens could become the face of interesting side projects or new insights into what this OEM's ecosystem could deliver.
      This year's SDC also debuted new tools that may make ends like this even easier in the future. They include EastST, which might replace self-contrived playback modules in order to check that content is running on a given TV as planned. Wits is the perhaps overly on-the-nose term for a new tool that allows immediate uploads of code edit to a Tizen-based TV, so that the developers can view said updates without delay. 
      However, the most important user-facing new facility here may be TIFA, or Tizen Identifier For Advertising. It allows advertisement opt-outs that may be more informative than ever before. It is less than super-clear why Samsung has taken such steps; however, a prime candidate rationale is to raise awareness of Tizen's open-source and cross-platform nature. Accordingly, it may pull target products into an ecosystem that also includes essentially Linux-based smartwatches, other wearables and pre-existing Samsung TVs.

      I am developing an alarm management application on a wearable device. It is a Web application (HTML and Javascript). When the alarm is triggered, in addition to sending the alarm status to the control panel, it should record the sound all around the device. This recording should arrive, in real time, in the operations center, publishing the audio stream on the reference Wowza server.
      Thanks in advance!

      Hi,

      I want to run a Smart TV application in Tizen Studio emulator. The application was not originally created using Tizen studio. The application is made using JavaScript library "TV Application Layer". 
      The application can be clonned from https://github.com/bbc/talexample .

      To run the application in web browser, do the following steps using cmd prompt or git bash:
      1) git clone [email protected]:bbc/talexample.git
      2) cd talexample
      3) npm install
      4) npm start
      then go to http://localhost:1337/

      I can run this app in web browser. I can also run any application in the Tizen emmulator, which was originally created in Tizen Studio. But I don't know how to run the above mentioned smart tv app in Tizen Studion Emmulator/ Simmulator. When I try to run in the emulator, it gives the following error:
      ""Launching New_Configuration" has encountered a problem. This is an error in the configuration file."



      Maybe, it needs some configuration in both the Tizen studio emulator and the smart tv application.
      Please, tell me any solutions to run the app in tizen studio emmulator.

      Thanks
      Sujan

      PVS-Studio team regularly checks different open projects and publishes articles on the results of these checks. This time, Andrey Karpov (CTO) accomplished the checking of some projects that are part of the Tizen operating system and has detected about 900 errors. The article is devoted to the review of many of these errors and will be useful both for beginners and experienced developers.
      The types of errors that will be discussed in the article:
      CWE-14: Compiler Removal of Code to Clear Buffers CWE-131: Incorrect Calculation of Buffer Size CWE-134 Use of Externally-Controlled Format String CWE-393 Return of Wrong Status Code CWE-457: Use of Uninitialized Variable CWE-476: NULL Pointer Dereference CWE-562: Return of Stack Variable Address CWE-563: Assignment to Variable without Use ('Unused Variable') CWE-570: Expression is Always False CWE-571: Expression is Always True CWE-690: Unchecked Return Value to NULL Pointer Dereference CWE-697: Insufficient Comparison CWE-762: Mismatched Memory Management Routines CWE-770: Allocation of Resources Without Limits or Throttling CWE-787: Out-of-bounds Write CWE-805: Buffer Access with Incorrect Length Value It is impossible to describe all the 900 errors, that is why most of them will be provided in a list. However, if you wish, you can examine each of the found defects, using the information provided about the location of the error.
      According to the results, there is a prediction in the article, that the PVS-Studio analyzer can identify about 27000 errors in this project. This article demonstrates that during the development of the large projects, static analysis is not just a useful, but an absolutely necessary part of the development process. Get some coffee and cookies, as there is a programmer thriller waiting for us.
