Our productivity tremendously depends on the tools we use. One of the fundamental tools for the software developers, researchers and analysts is the programming language. There are no silver bullets, each language fits the best for the specific purpose. Sometime it’s critical to prototype fast and we often use Python, but when it comes to the performance then C/C++ is the standard choice.
The Open Source movement significantly accelerated evolution and capabilities of the software ecosystems. It was literally impossible to build a full-fledged operational system within one-two yeas no so long ago. You can argue that Linux did it, but Linux was only a kernel that uses GNU ecosystem being developed many years before. In contrary, Redox OS appeared in the end of 2015 being developed using Rust language ecosystem and become probably the most secure existing OS. This is an excellent example of how the language selection impacts the project destiny (execution speed, reliability, security, development community, etc.).

First article: Adafruit 32×32 RGB LED Matrix Panel unboxing

I’m starting a series of articles about how to render real time 2D/3D graphics on RGB LED matrix panels with a Raspberry Pi. Even if the resolution of graphics is very low (32×32 pixels for a 32×32 LED display), drawing 3D stuff on that kind of display is very cool!

3D-Tech News Around The Web / globjects 1.0.0 released
« on: November 21, 2016, 04:52:25 PM »
CG Internals releasedglobjects version 1.0.0. globjects is a cross-platform, object-oriented open source library for the OpenGL API. It facilitates a modern, less cluttered, and less error-prone use of the OpenGL API: e.g., it reduces the amount of OpenGL code required for rendering and facilitates coherent OpenGL use by means of a type-safe abstraction layer based on glbinding and OpenGL Mathematics (GLM). Common rendering processes are automated and missing features of specific OpenGL drivers are partially simulated or emulated at run-time.

OpenGL uses the concept of states (e.g., point size, rasterization state) and objects (e.g., textures and shaders) by design. Since OpenGL is a C API, objects are referenced classically using handles. globjects replaces these handles with classes for each object and exposes their associated OpenGL functions and provides additional tools for convenience. For example, a globjects texture encapsulates OpenGL texture creation, initialization, modification, and deletion, as well as a default texture setup.

Code snippet:
Code: [Select]
auto program = new globjects::Program();

program->attach(
  globjects::Shader::fromString(GL_VERTEX_SHADER, vertexShaderSource),
  globjects::Shader::fromString(GL_FRAGMENT_SHADER, fragmentShaderSource));

program->setUniform("extent", glm::vec2(1.0f, 0.5f)));

globjects can be used in rendering frameworks and engines as a rendering API wrapper for ease of use. Furthermore, it is well suited for learning OpenGL and its concepts as it communicates modern OpenGL (and automatically uses fallback implementations within unified interfaces).

actually, nvflash utility is NVIDIA software or third party software?

Good question! According to the number of occurrences of "NVIDIA" or "NVIDIA Corp" in the exe, nvflash is likely developed by NVIDIA. This link says that nvflash is written by NVIDIA.

Change log for October 25, 2016 Vulkan 1.0.32 spec update:

  * Bump API patch number and header version number to 32 for this update.

Github Issues:

  * Add automatic visibility operations to the presentation engineE when
    doing a queue present in flink:vkAcquireNextImageKHR. Removed all
    references to MEMORY_READ that referenced WSI - they no longer make
    sense (some aspects of public issues 128, 131, 132, 261, and 298).
  * Document valid non-boolean +externsync+ attribute values for <param>
    tags in +vk.xml+ (public issue 265).
  * Add valid usage to slink:VkImageCreateInfo requiring that
    pname:arrayLayers be 1 for images of type ename:VK_IMAGE_TYPE_3D
    (public issue 319).
  * Add missing captions to figures in the <<textures,Image Operations>>
    chapter (public issue 334).
  * Clarify WSI interaction with exclusive sharing mode (public issue
    344).
  * Added explicit language clarifying the allowed queue usage of
    resources created with ename:VK_SHARING_MODE_CONCURRENT (public
    issue 386).
  * Require that the
    slink:VkDescriptorSetLayoutCreateInfo::pname:binding members of the
    pname:pBindings array passed to
    flink:vkDescriptorSetLayoutCreateInfo all be distinct (public issue
    391).

Internal Issues:

  * Remove empty validity blocks from +vk.xml+ and suppressed broken
    validity statements and added missing statements to explicit
    validity. Doesn't affect output, other than some statements
    appearing in another block now (internal issue 513).

3D-Tech News Around The Web / EVGA GTX 1070/1080 Overheating Issues
« on: October 24, 2016, 06:54:13 PM »

So it seems like the EVGA series have got a hotspot, which reaches over 100 °C around the VRAM/VRM area (micron vram only allows up to~95°C). This leads to either the weird black screen bug or to combustion of certain modules around the area.

- Word of warning: The EVGA 1080 blackscreen/fan bug is based on a hotspot, which pretty much affects their whole pascal line @ reddit
- EVGA 1080 FTW Thermal imaging might explain black screen issues @ reddit
- Caution: EVGA 1070 and 1080 series cards may have a hardware fault  @ reddit

- Tom's Hardware test of the GTX 1080 FTW with FurMark


- EVGA reply on EVGA forums

“The test used in the referenced review from Toms Hardware (Germany) is running under Furmark, an extreme usage case, as most overclockers know. We believe this is a good approach to have some idea about the graphics card limit, and the thermal performance under the worst case scenario. EVGA has performed a similar qualification test during the design process, at a higher ambient temperature (30C in chamber) with a thermal coupler probe directly contacting the key components and after the Toms Hardware (Germany) review, we have retested this again. The results in both tests show the temperature of PWM and memory is within the spec tolerance under the same stress test, and is working as originally designed with no issues.
 
With this being said, EVGA understands that lower temperatures are preferred by reviewers and customers.
 
During our recent testing, we have applied additional thermal pads between the backplate and the PCB and between the baseplate and the heatsink fins, with the results shown below. We will offer these optional thermal pads free of charge to EVGA owners who want to have a lower temperature. These thermal pads will be ready soon; and customers can request them on Monday, October 24th, 2016.  Also, we will work with Toms Hardware to do a retest.”
 
Thanks,
EVGA
