I want to buy a mi notebook 14. In the spec sheet it says it has a Nvidia graphics card. I know a few friends who bought a laptop with dedicated graphics card, but they cant change the graphics card system wide. There is a way to change the graphics card for a specific applications, but I don't want that. So I want to ask, Is there a way to change graphics cards system wide?
There is a way to add a graphics card to a laptop, but it's not for gaming purposes. Strange as it might sound, you can plug one in to a USB port. Doing this gives you an extra graphics output so you can drive an external monitor as well as your laptop's built-in screen. If your laptop already has a VGA, DisplayPort or HDMI output, adding a USB graphics card means you can drive a third screen: you're not limited to two displays.
For example, this StarTech adapter gives your laptop an HDMI output: https://www.amazon.co.uk/StarTech-com-External-Video-Monitor-Adapter/dp/B00H91BRZU/ref=sr_1_fkmr0_2?tag=pcagenius-21&ie=UTF8&qid=1521109083&sr=8-2-fkmr0&keywords=Startek%20USB%20graphics%20card&ascsubtag=06-3364133-11-0000000&geniuslink=true

Please apart from the 7" LCD touch screen, which other lcd screen can work with raspberry pi using windows iot core operating system
It is recommended to use the screen device which is listed in the Hardware compatibility list. As mentioned in the document, this list is not exhaustive. There are many other peripherals not listed on this page that are compatible with Windows 10 IoT Core. You may try with other screen, maybe it is also compatible. If you just want to use a display screen without touch input, in general the screen with HDMI interface is usable.
I'm working with beaglebones black always with Debian, more time with "Debian 7.9 2015-11-12 4GB SD LXDE" but in the current time i start working with "Debian 9.2 2017-10-10 4GB SD IoT".
I would like to know if it is possible, and if so, how to do it. So my objetive is when i flash the eMMC of the BeagleBone Black with a new Debian image disk, this image already contains some modifications that I always do after installing a new image, like for example:
-set up a static ip on /etc/network/interfaces
- and other little things
So the goal, is to know the best away (in Windows or Linux) open the image, do the modifications and build the image again, and ofcourse the programs to use.
Best regards,
David
Either mount and modify the SD card.
Or boot from SD and modify the SD card.
Or if you want to flash the same image to multiple devices, then flash to one and modify it to your liking. Once done use the appropriate script in /opt to turn it back into a SD card /flasher.
1) Boot your Beaglebone from the SD card enabling EMMC flashing
Plug the SD card and hold the boot button on the top right (near the SD card slot) and, while holding this button, insert the USB/power lead to connect the power. Keep holding the button until the LEDs start to flash.
(Complete info on http://derekmolloy.ie/write-a-new-image-to-the-beaglebone-black/)
2) Make your modifications to the image on EMMC
For example remove some packages, download updates, configure network interfaces, etc.
3) Dump EMMC content to SD
There are many ways to do this, but the easiest is to use the beaglebone-black-make-microSD-flasher-from-eMMC.sh script that should be already installed on the beaglebone or downloading it from Github.
4) Remove SD card and repeat from Step 1) on another beaglebone
The task:
OS: Mac OS X 10.9 +
Description:
There is web-camera connected to a Mac via USB. I need to discover a way of getting access to its' brightness, pan, color temperature, focus, etc.
I also need a way to apply image filters against camera's video stream.
I need to be able to control the camera while it is being used by other programs like Skype, so I can transmit for example video stream with increased contrast at Skype video call.

Solution:
This is the question.
As far as I understood I must to find custom kext (driver) in order to perform all this magic.
Could you please show me right direction, libraries, drivers, etc.
You can use opencv library to capture camera frames, apply filters, etc.
http://docs.opencv.org/2.4/doc/tutorials/introduction/display_image/display_image.html
Then you can feed a virtual cam that can feed into Skype, etc.

There also many open source virtual webcam available.
I hope this helps.
I have an AVerMedia card connecting the TV to laptop by PCI and USB. I want every time I save a screenshot from TV, the image will be auto-sent to PC.
The problem is, I have no clue where to start. I read all posts related to AVerMedia card like this in Python or this in C# or this in C++, but still no clue where to start.
Any advice is appreciated.
I am looking for some advice/input on writing a device driver. I have never written one for windows before, let alone for bluetooth.
Can you recommend a book or website or something to get me started? I have the windows driver kit, and the examples therein but with out some place to start I am dead in the water.
The specifics: My friend gave me his mac Magic Mouse. I have a windows 7 machine. With the mouse set up as just a generic HID device it works ok as a two button mouse with no scroll, the motion is smooth and the acceleration what you expect in a windows mouse.
The mouse actually has a fairly good lpi resolution, making it pretty sensitive. There are mac drivers available, extracted from bootcamp. They kind of work. The cursor will randomly freeze or stop responding to the mouse's movement, which is buffered, and then leap once whatever has caused the stall stops. As an added touch the mac drivers make the cursor move like it would on a mac, with that logarithmic acceleration, that will completely throw off any windows user. With the driers you get vertical and horizontal scroll, but that's it. There is no multi touch functionality, and you can't change any of the behaviors, like acceleration. There isn't multiclutch for windows, or other 3rd party software for a multi touch mouse.
So I figured I would endeavor to make my own drivers and multi touch functionality in windows for this thing. I know mac will never support it properly under windows and windows won't write there own drivers until there is a reason.
Also if any one knows of any one else trying to do the same or similar things, point me to them.
