Tech innovation remains one of the greatest achievements of man to date. If you look around, almost everything is tech based, and it would be an entirely different world without technology. While this achievement continues to influence the way people live and conduct themselves, another challenge is threatening to wipe out the benefits of technology and that is - cyber-crime.

This is where tech savvy individuals try to manipulate technology to suit their selfish purposes. This is a very dangerous activity because it leads to data breaches, loss of money, denial of access to your own data and loss of valuable information among other negative effects.

The damage caused by cyber-crime is expected to hit $6 trillion by the year 2021 since it is one of the fastest growing forms of crime today globally. Those who suffer the most are businesses and institutions because they are the ones that are usually targeted by cyber criminals.


Common types of cyber attacks

When it comes to cybercrime, no operating system, application or hardware is immune. However, the security vulnerability is high among the applications followed by the operating systems and to smaller extent - the hardware. This is attributed to the increased development and use of applications compared to the others.


Cyber-attacks come in the form of malware which is malicious software that gets into your computer when you open an attachment or click on a link to download a file that contains such software. Another way is through phishing or pretending to be someone or something else to trick you into responding to something like an email that you wouldn’t do in normal circumstances.

Others include Denial of Service (DOS), SSL attacks, brute force attacks, DNS attacks, port scans and backdoor attacks among many others.



Cyber security vulnerabilities

  • Security misconfiguration
  • Misconfigured web servers and applications are the common ways of vulnerabilities that give entry to cyber-attacks. This is usually through the use of outdated software, using debugging modules, using default accounts, passwords and keys and running unnecessary programs on your system. All these actions can be very catastrophic because cyber criminals will easily take charge of your system.
  • Poor authentication and session management
  • Lack of proper authentication measures will expose the users’ passwords, session IDs, and even accounts. Cyber criminals will then use that information to impersonate other users or steal sensitive information that users have access to.
  • Encryption flaws
  • Lack of encryption of sensitive data, weak algorithm usage and poor key generation and management can be a paradise for cyber attackers as all this will expose your sensitive data whether it is at rest, in transit or backup. This can also happen to the user browsing data, and so you should encrypt your sensitive data with strong encryption algorithms to minimize the chances of attacker’s success.
  • Buffer overflows
  • Buffer overflow vulnerability occurs when your application puts more data in the buffer than it can handle. This will mean writing outside the buffer space where attackers will easily overwrite the content and cause program crashes, data corruption or execution of malicious code.
  • Injection flaws
  • This happens when an application sends untrusted data to the interpreter. When attackers carry out an injection attack, they can get access to sensitive data which might further lead to data loss or denial of service.

According to one of the cyber security firm Michigan based experts, cyber criminals always target systems that happen to have a particular tech flaw because it is easy for them to break in.

These are things that may be hard to detect on your own, and this is why businesses are investing in cyber security providers to shield their businesses from cyber-attacks.

Gnome desktop is being accepted again by Ubuntu community after the announcement of Unity-8 is going to be buried. I am not going to talk about this new again since we already did and this post is about theme. T4G-V2 theme is created by a guy from gnome-look named "paulxfce", this theme is heavily modified version of popular Arc theme but with transparency items. This theme is specifically targeting Gnome desktop and do not expect it to work on other desktops, if you are using Gnome 3.20 and up versions then you are lucky to have it on your desktop. It offers bigger header-bars, window-frameless, transparent elements (all gnome-3 window backgrounds have transparency), graphical elements redone (new option/check-buttons; switch-buttons), added shadows beneath the header-bars.
It is available in three variants for GTK, as well as for Gnome Shell, you can choose whatever you feel is fit for your desktop; Black-Dark: The black-colored windows with dark sidebar in the file-manager, Black-Light: The black-colored windows with light sidebar in the file-manager, Blue-Light: The dark-blue colored windows with light sidebar in the file-manager. Since this theme is in active development if you encounter any issues with the latest version of the theme then report it to developer and hopefully it will get fixed in the next update If you are using other distribution you can directly download theme from its page and install it manually. Obsidian icons used in the following screenshots. You can use Gnome-tweak-tool to change themes/icons.

Cinnamon is a GTK+-based desktop environment. It originally started as a fork of the GNOME Shell, which is a user interface and was initially developed by (and for) Linux Mint. Cinnamon provides many features, including: Desktop effects, including animations, Applets, Desklets, and transition effects; A movable panel equipped with a main menu, launchers, a window list and the system tray; Various extensions; Applets that appear on the panel; Overview with functions similar to that in GNOME Shell; and Settings editor for easy customization. It can customize: The panel, The calendar, Themes, Desktop effects, Applets, Extensions.
Mint team released new version 3.2 of Cinnamon with new features and bugs fixes, rich settings to enhance desktop using Cinnamon Control Center. In version 3.2, and similar to MATE or Xfce, Cinnamon is an entire desktop environment built on GNOME technologies. It still uses tool-kits and libraries such as GTK or Clutter and it is still compatible with all GNOME applications, but it no longer requires GNOME itself to be installed. It now communicates directly with its own backend services, libraries and daemons: cinnamon-desktop, cinnamon-session and cinnamon-settings-daemon.

There are few standard ways to manage sources in Linux operating system, from command-line which can be difficult for some new users and built-in GUI way doesn't offers much (beside add and remove PPA). Aptik application first introduced in 2014 which made its way in community fairly easily. If you use standard version of Ubuntu and have many PPAs added in your system and you want to upgrade then this tools comes very handy and let you upgrade your OS quite easily, once you upgrade the OS you can re-install all the packages which were removed before upgrade or you can choose your strategy for upgrade process. Not only for upgrade, if you have another system that run Linux and you want to transfer packages from one to another then in that case it can be very useful tool.
It lets you backup and re-add all PPAs, installed packages (PPA/system/manually installed Deb), application settings, icons, themes, users/groups, data of Home directory and schedule tasks with a single click. Further more you can back and restore packages individually.

Do you still think that to work with a certain USB device you have to have it physically attached to your computer? In this case you haven't heard of USB Network Gate yet! USB Network Gate is available for different platforms, which includes USB Network Gate for Linux. The latest version 4.0 allows working with any USB device even in those "seems impossible" situations when a USB device is oceans away from you.

With USB Network Gate for Linux one can share any USB device on a computer (server) and then access this device from a remote location (client machine) and use it as easily as if this device was plugged into client computer directly. The technology works over Internet/LAN/WAN types of networks.

This means that no matter how many office workers need to use the same device and how far they are from each other and the device itself, you won't need to invest in more devices - everyone can access and use the device and all of its properties.
In case you were wondering what server and client parts are, they are all combined in one application, you just choose which one to set up on every computer. Pretty convenient and no special knowledge is needed.

Here are a couple of examples when USB Network Gate for Linux can be used:


Access multi-function device from any part of your office space
Sharing a multi-function device is probably the most common case where many people may want to access it from different machines. And such device is too big to carry around the building. The solution USB Network Gate for Linux offers is simple and really convenient for everyone in the office. You just need to install the app on a computer with MFD plugged in (server) and on computers of all office workers (clients) who are going to need the device now and then. Share the multi-function device from the server computer with USB Network Gate for Linux.

Aurora Next:

Aurora-Next theme isn't new but it's initial release was back in early 2015 and it looked great at that time and looks even more better, there are three variants in this suite and support almost every desktop such as Unity, Gnome Shell, Xfce, Cinnamon, Mate and so on but not compatible with KDE. You can choose from Blue, Green and Red variant from this suite as per your requirements. There are three Gnome Shell themes and Cinnamon theme with every variant, the supported versions of GTK are 3.20 and up. Numix-White icons used in the following screenshots.

There aren't much theme development going on for Ubuntu 16.10 Yakkety but there are still people who are doing their jobs behind the scene for you to make your desktop as fancy as possible. Since in Ubuntu 16.10 changed a lot and it takes a lot of time to rewrite the theme from scratch. Dark Aurora theme isn't dark but it looks great and it is available for Gnome Shell, Unity, Cinnamon, Xfce and compatible also with other desktops. Dark Aurora theme is kind of grayish color theme and it's easy on eyes as developer mentioned on the theme page. There are four variants in this theme and we've added all versions to PPA and supports GTK 3.12/3.14/3.16/3.20/3.22 available for Ubuntu 17.04/16.10/16.04/14.04/Linux Mint 18/17 and Gnome Shell theme versions 3.14/3.16/3.20/3.22/3.24 available. If you encounter any issues with the latest version of the theme 3.20/3.22 then report it to developer and hopefully it will get fixed in the next update If you are using other distribution you can directly download theme from its page and install it manually. You can use Unity Tweak ToolGnome-tweak-tool to change themes/icons.

Now a days there are much themes are in development for Gnome Shell because every new release of Gnome Shell makes old theme highly incompatible and bit difficult for creators to manage their themes for newer version of Gnome Shell. But there are still some people who are working on Gnome Shell themes. Here is one of the theme called Mist, basically this theme is inspired by the appearance of the GDM3 login manager, the main goal of this theme is to make Gnome Shell fully transparent. This means a panel that blends right into the desktop, simple flat, transparent buttons, and the bare minimum when it comes to menus and elements that overlap the work-space. This theme is compatible with Gnome Shell 3.24/3.22/3.20/3.18/3.16 and 3.14 versions, you need to enable user-themes extension in Gnome-Tweak-Tool to change Shell theme.


MPV video player is forked from mplayer2 and MPlayer, MPV supports wide variety of audio and video file formats. It offers some of the features with the former project while introducing many more. It is an command-line video player as well as offers GUI, it is lightweight and cross-platform available for Linux, Mac and Windows. From command line MPlayer's options parser was improved to behave more like other CLI programs, and many option names and semantics were reworked to make them more intuitive and memorable.
High quality video output: MPV has a OpenGL based video output that is capable of many features loved by videophiles, such as video scaling with popular high quality algorithms, color management, frame timing, interpolation, and more. While mpv has no official GUI, it has a small controller that is triggered by mouse movement. mpv leverages the FFmpeg hwaccel APIs to support VDPAU, VAAPI, DXVA2, VDA and VideoToolbox video decode acceleration. In addition, it features better pause handling, VDPAU improvements, support for modifier keys, correct color reproduction, better handling of audio and video synchronization, high quality subtitles, as well as support for playing multiple files at the same time. Another interesting feature of mpv is the ability to play video files a higher quality than many other open source multimedia player applications, simply because it relies on the FFmpeg’s hwaccel APIs (supporting VAAPI, VDA and VDPAU video decode acceleration).
