When you have linux there are some times you must find a way to do some things differently.

That time is one of those. Nikon firmwares are coming in exe files (windows) or mac files. But not linux.

But that doesn't mean you can't upgrade your firmware in your camera.

You need to do the following steps:

1. Download your firmware from the official link: https://downloadcenter.nikonimglib.com/en/index.html.
   
2. Download the Windows Firmware.
3. Copy the file to a new folder.
   
4. Open the terminal.
   
5. Go to the folder you put the folder (i.e. cd Desktop, cd Firmware).
6. Unpack the file with unrar e file.exe ( change "file" to what is the name of your filename of the firmware).
7. Format your SD card as per Nikon instructions within your camera.
   
8. Take out the sd card and put it into your PC.
9. Copy the two files that have been extracted (firmware.bin and gpsfirm.bin) to your sd card.
   
10. Then open your camera (with your sd card) and go to menu --> settings --> firmware.
    
11. And you will see the message to upgrade your firmware.
12. Don't close your camera until the upgrade is finished.
13. That's it how you do it from ubuntu.

Lately i have started to upload more often photos on my account on instagram. But because i have dslr and underwater compact camera, it was annoying to have to move on my smartphone or on google photos and later to download them on my smartphone so i can be able to upload them on instagram, since instagram doesn't have native app for ubuntu.

I tried many ways to do it directly from my computer, but only 2 ways had success.

The first was from google chrome to press right click on my mouse and select "inspect" and then press the small button on top-left which says "Toggle device toolbar" and choose from the console tab "Android Browser" so it can transform it into a mobile browser.

And the second it is the Ramme app from Github. It has an issue with javascript, and it shows a message but still it works perfect like to be inside the original instagram app on my phone. You can see the screenshot, where the last 2 photos have been uploaded with Ramme app on my ubuntu laptop.

And now finally i can upload easy all my photos directly from my computer.

Step 1: Install browser add-on

• For Google Chrome, Chromium, and Vivaldi: Chrome web store.
• For Firefox: Mozilla Addons.
• For Opera: Opera Addons

Step 2: Install native connector

​sudo apt install chrome-gnome-shell

One of the greatest alternatives to Photoshop is Pixeluvo.

It's easier than photoshop and with the most features of it. Let's see if it will improve in the future! (i hope it will improve) 
And the best is, that is available for Windows and for Linux (Ubuntu and Fedora).
It is not free but the price is very good (about $32).

I installed it on ubuntu 17.10 (with gnome shell):

• sudo apt-get install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0 gir1.2-clutter-1.0
• Download the ZIP/Tarball, extract the archive
• make install
• mkdir ~/git_projects
• cd ~/git_projects
• git clone git://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git
• mkdir -p ~/.local/share/gnome-shell/extensions
• cd ~/.local/share/gnome-shell/extensions
• ln -s ~/git_projects/gnome-shell-system-monitor-applet/system-monitor@paradoxxx.zero.gmail.com
• gnome-shell-extension-tool --enable-extension=system-monitor@paradoxxx.zero.gmail.com
• REBOOT the computer!

I was fixing a laptop with lubuntu and i didn't know the system password that the user has set. So after research i found an easy way and not that askubuntu and other sites were suggesting.

• The easy step is open a terminal.
• Write "sh"
• And then write "passwd username" .... Change the username with what is your username on the pc you want to change the password (e.x. George)
• And then you type the new password.

If you want to have access to your smartphone on ubuntu you have first to mount it by installing mtp-tools.
Copy the following command and put it on the terminal:
​
sudo apt-get install mtp-tools

First of all thanks to WineHQ for give instructions how to make windows programs work on ubuntu!

I downloaded 32bit trial photoshop cc and followed the instructions from winehq.

I didn't have to install something because i was using photoshop cs6 portable and already have installed the following.

sudo add-apt-repository ppa:ubuntu-wine/ppa 
sudo apt-get update 
sudo apt-get install wine1.7 winetricks

winetricks atmlib gdiplus msxml3 msxml6 vcrun2005 vcrun2005sp1 vcrun2008 ie6 fontsmooth-rgb gecko

So, i followed the instructions by changing the winecfg on Windows 2008, disabled internet, and installed photoshop. Then i changed again winecfg on windows 8, replaced atmlib (following file) so can photoshop be activated and voila is running perfect.

The system load indicator shows you graphs of your system performance on your panel – like the old GNOME System Monitor applet used to. It shows a graph of your CPU activity by default, but it can show graphs for more than one type of resource at a time – from its preferences, you can enable graphs for network activity, memory, and other system resources.

Install it via terminal:

sudo apt install indicator-multiload

Ένα απίθανο προγραμματάκι που μετατρέπει τα δισδιάστατα βίντεο (2D) σε τρισδιάστατα (3D) και όχι μόνο.

Έχει επιλογές κιόλας σε τι τρισδιάστατα βίντεο να τα μετατρέψει. π.χ. Κόκκινο-μπλε ή μια οθόνη δίπλα στην άλλη.
