.Net Core 1.0 Released! Or installing .Net Core on Debian

This was a great news to me that .Net Core 1.0 was released. I already was trying .Net Core RC2 on my Debian 8.x so I prepared to go through the installation process of new release. Surprisingly installation of .Net Core 1.0 described in Install for Debian 8 on Microsoft site was very smooth in comparison to beta versions. All I had to do is to clean up my previous install from ~/.dotnet go through the instructions on install page and "Hello World!" programs runs. Very pleased to see that improvement.

So here I am going to provide some links to what to do next once you get your install done too.

Recording Music CDs under Win 7

From days of Windows 95, Windows 98, Windows XP CD/DVD burners and writers were only coming out on the market and computer users were required to install additional software, which will allow them to burn CD and DVD disks. Disk writing software like Nero was included for free with the CD/DVD burner you could buy for your desktop computer or included on new laptop. Modern Windows operating system like Windows 7, Vista, Windows 8 and Windows 10 already have built in support for burning CD / DVD music, data and video disks. Users can use included Windows Media Player to rip and burn music CDs.

Under Windows 7 to burn audio CDs insert CD disk in disk drive and in Windows Media Player open Burn tab, drag music files you want to burn. The blue bar shows how much space left on the disk. Once files are selected click Start burn to start recording on the disk.

Data CDs / DVDs can be burned directly from Windows Explorer. Disk image files with ISO extension can be burned using right mouse click on the file and selecting "Burn disk image".

If you still require more features than the basic functions to burn disks look through available free and commercial applications available on sites like filehippo

Install NVidia Graphic Drivers on ASUS ROG G750JW

ASUS ROG G750JW comes with GEFORCE GTX NVidia 2GB graphic card. To get a full power of this card on Debian we need to install nvidia drivers for it. Debian Wiki NvidiaGraphicsDrivers article describes several ways to do it. Here I am going to summarise the steps that worked for me.
  1. Add SteamOS repository to /etc/apt/sources.list.d/steamos.list, for example:
  2. deb http://repo.steampowered.com/steamos brewmaster main contrib non-free
  3. Update the list of available packages. Install the appropriate nvidia driver and related packages from SteamOS repository:
  4. # aptitude update
    # aptitude install -t brewmaster libegl1-nvidia:amd64 libgl1-nvidia-glx:amd64 libgl1-nvidia-glx:i386 libgl1-nvidia-glx-i386 libgles1-nvidia:amd64 libgles2-nvidia:amd64 libnvidia-eglcore:amd64 libnvidia-ml1:amd64 libxnvctrl0 nvidia-alternative nvidia-driver nvidia-driver-bin nvidia-kernel-dkms nvidia-modprobe nvidia-settings nvidia-vdpau-driver:amd64 xserver-xorg-video-nvidia
This will also install the recommended nvidia-driver package. DKMS will build the nvidia module for your system. Restart your system to enable the nouveau blacklist.

Debian 8 – Jessie - Enabling Wifi on ASUS ROG G750JW

Debian Jessie installer managed to detect most of hardware during install like LAN, sound and video, but WIFI had to be configured separately.
  1. Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:
    # Debian 8 "Jessie"
    deb http://http.debian.net/debian/ jessie main contrib non-free
  2. Update the list of available packages. Install the relevant linux-headers.
    # apt-get update
    # apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms
  3. Unload conflicting modules:
    # modprobe -r b44 b43 b43legacy ssb brcmsmac
  4. Load wl module:
    # modprobe wl
  5. Edit /etc/network/interfaces and comment out or remove allow-hotplug eth0

Setup Lexmark X8350 printer under Debian Linux using Virtualbox and Win XP

After installing Debian 8.0 Jessie I failed to locate drivers for my multifunctional Lexmark x8350 printer. The Windows printer driver support was available only up to Vista, there were no drivers for Windows 7 and above.  So I decided to try to setup Windows under Vrtualbox with pass-through USB device. First I tried with Windows 7 Virtualbox client (Under normal Win 7 install printer drivers for Vista worked fine), which was very very slow to install and I did not get it to print, only to scan. So the best option left is to install Win XP. This article will describe installation of Lexmark printer on Win XP Virtualbox client.

Step 1: Install and configure latest Virtualbox package and extensions

I am not going to go describing installation of Virtualbox and extensions. www.virtualbox.org download page has clear instructions on what to download and install. After installation is done make sure that your /etc/fstab has the following line:

none /proc/bus/usb usbfs devgid=500,devmode=664 0 0

The devgid has to match your gid of your vboxusers group. Also make sure that user you logged in as is member of the vboxusers group. Please log out and log back in after adding it to a group.

Step 2: Setup Win XP client and configure USP pass-through

Make sure that Lexmark printer is connected to USB. There is no need to turn it on yet.

Start Oracle VM Virtual Box Manager. Click New. If you have already setup Win XP client just click on it and scroll down to USB section in Options. Click on USB link. Select USB 2.0 (EHCI) Controller, click on icon with green cross and select your printer from list. Click OK.

Now you can start Virtualbox client and complete Windows XP and printer setup. You can use your disc that comes with printer or download drivers from Lexmark support site.
