Configuring Primefaces application with glassfish and nginx

July 21, 2016 in Programming, Source Code, Tips & Tricks, Tutorial by admin

primefaces-logoOne of the issues I had these days was installing an Primefaces application in Glassfish application server  running in a container with no external IP address and configuring a nginx front-end for it. While making the two servers work together is just a matter of right configuration files, issues start to pile up when we want to have the context path removed from the nginx. Tried couple of approaches, using URL rewrite, proxy pass, etc, but in the end all of them ended up with links and resource files (ex. CSS files for the themes) not being found. Eventually after many tries ended up with this solution, which (so far) seems to work without any issue. Read the rest of this entry →

Supercharging Android Apps With TensorFlow

May 28, 2016 in Android, Java by Adrian Marius

android-logoIn November 2015, Google announced and open sourced TensorFlow, its latest and greatest machine learning library. This is a big deal for three reasons:

  1. Machine Learning expertise: Google is a dominant force in machine learning. Its prominence in search owes a lot to the strides it achieved in machine learning.
  2. Scalability: the announcement noted that TensorFlow was initially designed for internal use and that it’s already in production for some live product features.
  3. Ability to run on Mobile.

This last reason is the operating reason for this post since we’ll be focusing on Android. If you examine the tensorflow repo on GitHub, you’ll find a little tensorflow/examples/android directory. I’ll try to shed some light on the Android TensorFlow example and some of the things going on under the hood.

Android-X86 Nightly builds are back

May 18, 2016 in Android, News, Tips & Tricks by admin

android-logoThe nightly builds for Android x86 (Marshmallow) are back for a while now and it seems they’re working as expected.

The bootable ISOs can be downloaded from this link for both 32bit and 64bit architectures. The build is made each night, freshly from the repository and unless the build fails, the ISO-s are updated.

It should boot either from USB or any other media. The page contains information about how to test it.

Step by step debugging firmware on the Aliexpress / EBay STM32 boards

May 9, 2016 in ARM, C, C++, Hardware, Linux, Microcontroller, Programming, STM32, Tips & Tricks, Tutorial by admin

arm_cortex_logoIn some previous topics (here and here) I wrote about some cheap development boards which can be acquired from EBay or Aliexpress. Since System Workbench for STM32 is freely available for a while now, let’s see how can we use it to generate a project, compile it, upload it to a board and debugging it step by step. We’ll use for this the board I got from EBay, but it works the same with the any STM32 other board I have and also with some self-made ones.

For being able to install firmware on the board and debug it, first we need to have a hardware part which will sit between the computer and the board. There are various models and versions of these jtag debugers and they can be ordered online or found pretty cheap on ebay (clones). Another way to get hold of one of these is to have a development board which comes equiped with JTAG adapters, like the STM32 discovery series of boards. Some of these JTAG debuggers allow even breaking apart the JTAG debugger from the development board itself (LPCXpresso series, the nucleo boards).
Regardless of which JTAG interface is used, it should be one which is known to work with OpenOCD, as we’ll use OpenOCD for debugging. In our case we’ll use the stm32f4 discovery board’s stlink2 side. However, Before using it as a JTAG debugger, we need to disconnect the STLink part from the discovery board, by removing two jumpers. Once that is done, the STLink itself won’t be connected to the discovery board and it’s SWD header can be connected to any other board. Read the rest of this entry →

Five free plugins hit the Ureal Engine marketplace

May 7, 2016 in Game Engines, News, Programming, Unreal Engine by admin

unreal-logo-smallUnreal Engine marketplace started to release code plug-ins. For start, 5 free plug-ins will assist you in gathering analytics on player data, provide support for REST server communications, allow you to load MODO material .xml files for 3D meshes and more.

MODO material importer by The Foundry

The Unreal Material Importer is a plug-in for Unreal Engine 4 that you can use to load MODO material .xml files and apply them to 3D meshes of a game level in the Unreal Engine 4 editor.
If you have a MODO scene, you can export 3D meshes in the form of .fbx files, and materials and textures as .xml files.
You can then apply the exported materials to the .fbx 3D meshes in Unreal Engine, using the Unreal Material Importer plug-in.

Skookum Script by Agog Labs Inc.

SkookumScript’s cutting-edge command console turbocharges your workflow (at any stage of development) by enabling you to query and manipulate any UE4 game as it runs on any platform—without disrupting your existing tools, C++ code or BP graphs. So even if you aren’t looking for a scripting solution now, try our console. You’ll love it. We promise.

Then there’s SkookumScript itself—a text-based, compiled language that is made for games. With key game concepts such as concurrency built-in, SkookumScript empowers the entire team—from light coders to C++ veterans—to create sophisticated gameplay with surprisingly few lines of code. Its addictively useful IDE features live code changes with instant turnaround, context-sharing with the UE4 editor, and remote debugging. It painlessly scales with team size and content, and benevolently bridges between C++ and Blueprints—changes in SkookumScript are reflected live in Blueprint graphs and vice versa. Wow!

Lovingly crafted by veteran game developers, battle-tested on the hit AAA titles “Sleeping Dogs” and “Sleeping Dogs: Definitive Edition”, and now in use on several upcoming AAA and indie games, SkookumScript fills your game development experience with cackles of megalomaniacal glee. Better coding through mad science!

Logitech gaming SDKs by Logitech

This runtime plugin links to our .libs which find and load our SDK .dlls shipped with Logitech Gaming Software. LGS and the SDK .dlls are responsible for all the work done to communicate to each of the devices. We designed this loading scheme to allow for older versions of our .lib to have support for newer devices by upgrading LGS. This takes the burden off the game developer by shipping a smaller .lib and also ensures future support.

This plugin enables the control of Logitech Gaming products by porting these SDKs to the UE4 engine:

• Logitech|G ARX Control SDK
• Logitech|G LED Illumination SDK
• Logitech|G G-Key Macro SDK
• Logitech|G LCD Gamepanel SDK
• Logitech|G Steering Wheel SDK

Small and cheap STM32F103 boards from aliexpress

May 3, 2016 in ARM, Hardware, Microcontroller, STM32, Tips & Tricks by admin

arm_cortex_logoRecently I was looking for some cheap boards which would allow me to play with the STM32F103 microcontroller and I’ve found that Aliexpress has couple of versions of them sold quite cheap by various sellers, with a very affordable price tag. There are various incarnations of these boards, and with difference in the price range, so I went with these two in the end:
