Emmabuntüs makes the promo video

You may know that Linux notes from DarkDuck is a long-lasting good relationships with the Emmabuntüs project. I reviewed their operating system multiple times. There was an interview with Patrick, the project leader. There was a report from the Cote-d-Ivoire journey of the project.

Emmabuntüs recently released a video where they explain the goals and reasons of the project, current achievements and show people who really use this operating system. You can also see the members of the project live.



DarkDuck also made a little contribution to that video. I translated the subtitles to Russian, so Russian-speaking community can also enjoy watching it. To select a subtitle language, please click on the gearwheel located at the bottom right of the window and pick the language you want.

Video: How to configure keyboard layouts in Cinnamon 2 and 3

I have recently written an article where I described the process of configuration of changing the default keyboard layout in Cinnamon Desktop Environment versions 2 and 3.

Some people prefer to see the video with the same steps rather than read them. That is why I created a video for you.

You can watch it below or visiting the link https://youtu.be/cOEwNDmAYzs

How to create list for LibreOffice Calc cell (video)

Spreadsheet is a convenient tool to make calculations. But that's the not the only use the spreadsheets have now.

Many people use spreadsheets as a tool to exchange information. For example, you can get a spreadsheet from your supplier with request to list your order details there. On another side, you can create a similar spreadsheet to your customer, or even for household needs: keeping budget, or inviting friends to the party. The range of spreadsheets' use is large.

There are many cases when you want to help either yourself or another people with working with the spreadsheet you composed. For example, you want to advise that certain cells can only contain a pre-defined set of values and nothing else. The best way to do so is to give users a drop-down list to choose from.

How-to video: Removing old kernels in Ubuntu

Once new kernel passes the test system, Ubuntu offers you to install it through its update system.
At the same time, old kernel remains in the system. It means that after some time of using Ubuntu, you may have a number of old kernels. They take your disk space and also may clutter the GRUB menu, although the latter issue is resolved in newer versions of Ubuntu.

This video shows you the way to remove old obsolete kernels from your Ubuntu installation.

The same approach is valid for whole Ubuntu family and derivatives: Xubuntu, Edubuntu, Kubuntu, Zorin OS, Linux Mint and so on.


Please remember that the "best practice" is to keep at least two kernels in the system: the current and the previous one. This is to ensure the fallback solution if current kernel fails for whatever reason.

How many old kernels do you have in your system? How often do you remove the obsolete kernels?

Linux for beginners (video)

Hi DarkDuck blog readers!

My name is Steve Barth, and I am a video producer for IT training company: CBT Nuggets. Part of my job is to produce a video podcast, with the goal of taking difficult IT concepts and making them easy to understand and entertaining to learn about. I write, film and edit the show with the help of our amazing CBT Nuggets trainers. But, I have a confession to make: My passion is video production.. so I'm not an IT or Linux guru.

When DarkDuck asked me to guest write a blog post, due to our recent Linux show, I scratched my head and then immediately enlisted the help of Shawn Powers, our own Linux trainer. Here's what he had to say about our Linux themed show.

How To Video Record Your Desktop

Screencasting software has sprung up all over the place in recent years, and there are a number of good reasons why you might want to use it to record your desktop.

Firstly, it’s a great way to create software tutorials that you can share with others. There are thousands of them on Youtube to date already, and companies use them to display clear instructions for their own products, as well as putting them to use for marketing purposes.

Screencasting is also useful if you’re having PC issues and need tech support – by recording your screen as you step through a problem, you can show the techie exactly what goes wrong where, and you’ll give them the best chance of helping you resolve the issue.

Here are some of the best tools currently available for recording your desktop. Some of them are OpenSource.

Four Top Open Source Screencast Applications

When you want to show people how to accomplish something on their computers, nothing works better than video. You can capture all the action on any desktop using any of several open source alternatives. We picked four applications that cover a range of users' needs. FFmpeg, recordMyDesktop, VLC, and CamStudio, between them, offer GUI and command-line usage, run on Linux and Windows, and provide basic or advanced functionality. The one thing they have in common is that they're all free and open source software.

Host Your Own Video with Flowplayer

Video can be a powerful tool to deliver information over the Internet for marketing, corporate training, or social media purposes. Most people who think of Internet video probably think of YouTube first, but sometimes public hosting is not the best option for your video. What do you do, for example, if you want to upload a confidential interview, or training material for your employees to use on the corporate intranet? You might want to incorporate marketing video on your site without any YouTube branding, or your corporate policy might block YouTube at your firewall. In these cases you can self-host videos with Flowplayer and make them available on web pages to anyone with a browser.

Record your desktop!

There is a good Russian saying: it is better to see once than to hear a hundred times.

That’s why screencasts are so important when you want to explain something.

I have written an article which was published by Wazi , and later on this blog, which compares four different options to record your screencast.

Feel free to read, share and recommend!

Today great resource Wazi published my post about Flowplayer, open source flash player for self-hosted videos.
Please welcome to read!

VideoJS - The Open Source HTML 5 Video Player

If you are like me then you were very excited about HTML 5's video tag. Simplistic, great functionality, and now it is even supported by all of the latest browsers. Video is just a source away, and easier than ever to portray high quality videos right on your website. HTML 5, like anything else, doesn't have everything we want. For example the biggest problem is a "full screen command." Even though you are able to specify the dimensions appropriately, you still want to be able to save space, and provide that option. Early on there were a number of options available to have a deluxe video player. There seems to be a frontrunner in this battle, and that is VideoJS.

VideoJS is a free open source player that includes everything you need for your HTML 5 video. It features a lightweight, easy to use design complete with controls you would like, including volume and fullscreen options. It is supported by the latest browsers including IE9, and Opera. It even supports devices like iPad, iPhone, and Android. Another great feature is the automatic fallback to Flash that it features that will give you the same quality video for IE6,7, and 8. This is essential if you want everyone to be readily available to see your video. You also have the option to chose from various "skins" to get your video looking just the way you want it. If you have enough talent you can even create your own skin using CSS. Lets take a look at how all of this works.

The first thing that you need to do is go to www.videojs.com. VideoJS acts in the same manner that jQuery does for Javascript, so if you have any experience using jQuery then this should be a familiar process. You have to download the latest version of VideoJS, unzip it, and then upload it to your server. Then they have simple code, on their homepage that you will need to copy and paste in order to have it working correctly. First you need to copy the script, and css links, and place them in the head of your HTML document appropriately. Next you need to add some Javascript that has already been coded, that just lets the browser know to trigger the VideoJS once the page has been loaded. Then the video for everybody just needs to be appropriately placed in your HTML, change the sources, and you can optionally include a Flash fallback if you want to. That's it! now you have perfectly operating video, that everyone can see. Just make sure you have the correct sources for your video, and for your references of Javascript and CSS.

Even with the ease the VideoJS has provided, some may not see the need to use this. There are a few important reasons why you should be using an HTML 5 video player like VideoJS. First, you are able to reach a wide audience through the dynamic compatibility the HTML 5 video player has to offer. This will ensure that you are reaching mobile users, and users of various web browsers. Another reason is this video player offers the great features of an HTML 5 video tag, with the options of customizable skins, and full screen options. Then you can also add a fallback Flash player for browsers that do not support the HTML 5 video tag. This is done automatically, so there is no need to create a browser detector with corresponding hack. Finally VideoJS will be great for SEO. Google has a pretty big problem segmenting Flash videos, which makes it harder for you to be seen in the SERP's. You used to have to make extensive site maps, but now the video tag is easily identified, and you can even add a title to describe the media. If you combine this with a white hat link building service, you will defiantly have a boost in traffic.

The VideoJS HTML 5 video play is an all in one solution to your video problems. You have cross browser compatibility, both with your videos, and with the look and feel. This allows you to reach a wider audience, and allows you to easily be seen by the search engines. This is the simplest way to have a fully function video player on your website, and even with the additional fullscreen option. VideoJS lets you incorporate fallback options for older browsers in the form of a complimentary Flash player. Try VideoJS once, and you will not be disappointed.
