Python 2.7 + PyQt5
Python
The script scans the storage on the subject of video-delices (video with an animated 3D scene).
It sorts by dates of the render and displays their list in the Qt window.
You can choose certain videos. Through #ffmpeg, one role will be created on their basis. Between the videos are inserts with information about the video. And also on the video itself are set titles with service information. The video is then placed on the #DLNA server (also, it was also set by itself). As a result, we just choose the necessary films, include a 3D TV and watch the work done on the "big screen".

Linux by network (PXE + NFS)
Linux & Unix
Start #linux on the workstations from #net by #PXE+#NFS. What releases the convenience of installing the OS on each machine, this scheme allows you to have one image of the system on the #server. And, for example, the installation of any software or adjustment of the library occurs at the same time on all machines. And also convenient #set and #management, for example, adding a new user, he can log in to any machine from the network and work, and even without a dedicated #LDAP server. Workstations can be used without disks, or only users’ files are stored on the local disk. And you can also make a network "home" on a separate network storage, which will allow employees to work on any computer and always have access to all their documents.

WinAPI + C
C & C++
To view the video, click on the work headline.
The essence of the task was in that to create a simple interface with a config in one text file. And the main thing that with the help of WinAPI you can create only the main window, well and get only the main events, exactly I don't remember what, like would only the focus of the window and the move of the mouse. Everything else needs to be done by yourself, that is. window, cursor, inscription, button, pressure effect, mouse focus, window focus loss, etc. This all needed to be drawn by itself through "Device Context" and WM_PAINT.
He did for the weekend, on Friday he received a task, all Saturday he broke his head how to make, on Sunday from morning he settled for the "studio" and in the morning he didn't lie down the way to open the work). More precisely even to say to understand how it works, not from scratch of the end, ballowed after schools yet with WinAPI, but at that time it was already possible to let 10 was engaged in the basic "Railways", invented how to realize and write.

Dynamic Redirect Request
System & Network Administration
#nginx receives the request, makes the request in #redis, by the domain key and sends the request further to the internal_net/virtual/#docker_containers to the corresponding #server.
The keys in the "domain" format: "ip-address backend" can be changed by sending the #traffic to the active at the moment #server.
For example, you can lift the #server/#containers/#virtual with a new version and redirect the entire #traffic to it without ceasing the work of the #site.

Online shop at OpenCart
System & Network Administration
Start the online store on the OpenCart engine. Basically collected on ready modules, but not a little effort went on that all these modules would combine one with another and correct them under the needs of the contractor (read to write the missing functions). Also implemented on #php 5.6 synchronization c #Microsoft #SQL, through #unixODBC. The work also used #javascript+#jQuery. The server is also uploaded by me (#nginx+#php-fpm+#mysql). Basic SEO is yours too, more precisely on your mistakes)

Plugin for Foundry Nuke
C & C++
Who doesn't know, this is a professional software for #visual effects, the specification of which is #processing #images and #squentions.
Plugin is written on #S. "Cayer" removes "#chromocay" (the technique of dividing the image into layers (using green or blue background)
They put the right background in place. The #Plugin works better than the #KeyLight is built. More soft boundaries, better processing small details, less artefacts.
The algorithm is not mine, but the realization is mine. It is not just the use of mathematical functions. A realization of some specific functions, such as #transformation between different #colored #spaces. When writing I had to remember #logorithm, #vectornu #algebru et al.

Temperature Controller Server
Embedded Systems & Microcontrollers
It is made on #Arduino. He picked up himself, so he wrote PO, not just "copy-paste". Available on the network, a simple WEB server is lifted, and http gives current temperature on all sensors. It can scan the "net" to the presence of new sensors and gathers infout from all. Almost ready was the GSM module with sending SMS at the alert, but connects not succeeded, went away)
