Linux is proven as the dominant operating system used by the most popular social networking sites and now experts are saying that the ‘Social Media Phase Of The Internet’ Is Over. That messaging is the new social media. Messaging and mobile moved into the enterprise in a big way.[1. The ‘Social Media Phase Of The Internet’ Is Over.] If their predictions are correct then Linux is will be the main player again with 81 percent of world smartphone market which isn’t surprising since Linux won the social web.
I’ve played around with gphoto2 quite a lot and I knew there was a simple way to get my DSLR camera to take a photo every 10 seconds and copy it to anywhere I’d like. When googling how to do this I found a really nice application with a gui call gTimelapse. It amazes me that programmers just decide to write these programs and share them openly on their websites including the source code. gTimelapse is written by Tim Nugent, its a really nice program for doing timelapse, really simple to set up and easy to use. I like the preview and thumbnail preview of all the images it captures as it goes along in real time. Big thanks to Tim for this awesome program.
I thought I’d document the extra packages I needed to install to make it easy for other Ubuntu users to compile the program. Basically download it from the link on the page at Tims site then extract it somewhere and run the following commands.
$ sudo apt-get install build-essential libgphoto2-2-dev libwxbase2.8-dev libwxgtk2.8-dev gphoto2
$ configure;make;sudo make install
The program will start and the rest is fairly straight forward. You probably want to change the max frames to 0 so that it records till you press stop. The other tip I would suggest that if you stop and start capturing make sure you set a new “Working Directory” in-between otherwise you will just overwrite the images you just captured.
I was pretty lazy and left a comment asking Tim for his mencoder command to put together the images at the end, his response was really quick which was nice.
Hi Chris, I think there should be a script in the src directory with some decent mencoder settings? Ah here we go, will make a 720p HD vid for Vimeo etc:
mencoder mf://*JPG -vc ijpg -mf fps=8 -vf scale=1280:720 -ovc x264 -x264encopts bitrate=5000:keyint=30 -o timelapse_1280x720_x264_8fps_5000.avi
Though I found that too jerky for my needs, Im sure its fine for his party video but I wanted moving clouds in mine so I changed the fps=8 to fps=25 and it was fine.
The other thing was that I shot in jpg normal which is 2144x1424px and I wanted my video to be 720p so I used David’s Batch Processor Gimp plugin to resize, crop and sharpen them a little before using mencoder. That gimp plugin worked really fast, its great.
It seems time consuming to capture the images, when I captured every 5 seconds for 30 minutes then encoded at 25 fps it only gave me around 14 seconds of video. So be prepared to spend a few hours to get a decent video. I think with my eeepc and nikon d90 with battery grip going outdoors I can capture for around 6 or 7 hrs.
When I went out to try this the weather was really crappy but it didnt turn out too bad, you can watch my video below or watch Brisbane Morning Time-lapse Test on youtube.

A common question by photographers who shoot in RAW is how to get a jpg the same as the one the RAW image file produces from the camera by using the RAW image file and a software package. In the screencast I talk about how to do that. Watch it above and you can also watch GNU/Linux Extract JPG from RAW NEF CRW using terminal, Nautilus, Digikam on youtube.
I haven’t made a screencast in a long time but I decided to share some info mostly about geotagging. I own a Nikon D90 and plan to buy a GPS unit that will write the global position system data to the exif metadata of my photographs and make them more manageable for me and allow me to do some cool things for visualising a map of my photographs.
A platform independent program to geotag images(use GPS data to store location information with the image).Uses external maps to fine-tune locations.
Anyone can use geotag to tag their photos very easily. Watch my video below.
Google is phasing out the internal use of Microsoft’s Windows operating system because of security concerns, according to several Google employees. The Financial Times reports that since early January, new hires were still being allowed to install Windows on their laptops, but it was not an option for their desktop computers. Google would not comment on its current policy.
Windows is known for being more vulnerable to attacks by hackers and more susceptible to computer viruses than other operating systems. The greater number of attacks on Windows has much to do with its prevalence, which has made it a bigger target for attackers.
Employees wanting to stay on Windows required clearance from “quite senior levels”, one employee said. “Getting a new Windows machine now requires CIO approval,” said another employee.
New hires are now given the option of using Apple’s Mac computers or PCs running the Linux operating system. “Linux is open source and we feel good about it,” said one employee. “Microsoft we don’t feel so good about.”
As usual I was reading planet TALO aka superuser network and read the post “Top Tools for Learning 2009” by Kerrie Smith.
It’s interesting to see that “educators” on the web are doing most of their computing using “Linux” and an “open source” web browser.
Lets look a bit closer at the top 10 software tools:
- Twitter – Linux
- del.icio.us – FreeBSD
- youtube – Linux
- google docs – Linux
- google reader – Linux
- wordpress – Linux
- slideshare – Linux
- google search – Linux
- Audacity – Free and Open Source
- Firefox – Free and Open Source
I know a secondary school student is more than capable of learning to build and run a web server but the way its taught in schools using IIS is really pathetic. The student doesn’t learn much and does it really empower them? No not all, it cripples them. I remember chatting to a young friend of mine about his early days in high school, he likes computers and studied ICT thinking it would be different in high school but it was the microsoft word training again, he told me he’d previously gone through the word training twice already in primary school. They are taught that pressing the “export as web-page” button is Web development so people should think about how much they can learn about word processing and word processor software on Ubuntu using open source software and compare it to what they learn and do now because obviously they aren’t learning anything useful about web development.
I don’t understand why there isn’t a government policy to have a preference for free and open source software yet or at least equity for students wanting to learn and use GNU/Linux. Imagine you work in a school as a computer/library assistant and there’s 40 or so pentium 3 computers in the store room and you want to use one to add a diskless web kiosk to the library, the computers are in the store room because they were replaced by newer computers with even bigger hard disks (the most expensive component?) and you wonder why they didn’t buy smaller cheaper hard disks if only 5gb of the 80Gb will ever be used, it would probably be worse these days.
Meanwhile the teachers are fighting for disk space on the server. Imagine asking a simple question; “May I use one of the computers in storage to add another computer to the library?”, obviously the first thing is the fact that those computers don’t work with the current version of windows, to cut a long story short if they’ve never heard of GNU/Linux then its likely they will reject the idea and sometimes give ridiculous reasons.
Its also a power issue, proprietary software users know all to well that you can gain power over people using software, its common in things like LMS’s and if you’re the guy who setup the school website then you can give people access to publish. There’s a lot of social politics involved in these things, whoever gets the better computer is not always the person who needs it.
Will the student wanting to use FOSS and GNU/Linux to learn about technology and software be allowed to do that in Australian schools? Choosing an operating system and software is part of the “Information Technology Systems Syllabus”, read the “Sample assessment task 1”. I wonder if the students have any rights or choice, perhaps it falls back to teacher preference.
If the general public knew about Ubuntu and the fact that unlimited copies are available for free, would they want a fair share of the systems running ubuntu in state funded education. Learning about technology shouldn’t be reduced to training kids to use proprietary products.
Most teachers Ive met say they’ve used “Linux” with their students but usually its just for a single day in the year.
So hows your favorite operating system do on the list of the top 500 supercomputers.
I’ve talked about Tux Paint on this blog over the years and produced an informative and slightly humorous Tux Paint demonstration video back in 2006. The video has been downloaded 1,066 times from internet archive.org and viewed 31500 times not including the 14000 views from the version with low quality audio which Ive deleted.
The most common question I get asked is “how do I get the stamps?“. All of the people who have asked are on the windows platform, I believe this is probably because on Debian/Ubuntu systems the stamp packages are installed with Tux Paint. So rather than continue to reply to all the email and comments I decided to write this howto and perhaps someone will do the screencast version.
Getting Tux Paint stamps for windows and mac osx
The steps are the same, visit the Tux Paint website, chose your operating system then download and install the optional stamps package.
Some of the people that asked me about the stamps must have been too excited at the time they downloaded Tux Paint and didn’t notice the optional stamps package or perhaps they didn’t install Tux Paint. If you’re having trouble you might need to ask an adult for help, if that fails just go colour.
Tux Paint stamps on Ubuntu
On Ubuntu we have advanced packaging tools, software management programs and remote software package repositories. Pretty much all the software on my system has been installed this way, its easier and more user friendly then installing software on other systems and the amount of top quality software you can install is amazing. Using search its easy to find cool new programs, for example if you’re a social media guru you might search for twitter, facebook or blog software, if you need a web server running a wiki you might simply install mediawiki and enjoy watching all the system dependencies get met. The two programs I’ll mention are the Ubuntu Software Center and Synaptic.
Ubuntu Software Center
The Ubuntu Software Center is new in Ubuntu 9.10, some people may not have upgraded so we will also look at Synaptic. Synaptic is usually installed on most versions of Ubuntu.
The Ubuntu Software Center is available from the Applications menu.
Simply use search, type tuxpaint and click the arrow and your done.
Synaptic is available through System Administration menu.
Again simply use Quick Search and type tuxpaint, Synaptic gives us more information about the packages, to install/uninstall software you tick the box and hit apply.
Tux Paint still reigns as the best educational paint software. Usually people are having too much fun with Tux Paint to think of it as an intelligent tutoring system within a highly interactive learning environment.
Tux Paint is available for free and as free software and you can also purchase the CD. It makes a great gift.
Unixmen.com report that almost the entire public sector in France, 96 percent, is using open source, according to a market survey. The most used applications are database management systems and content management systems.
A research firm, Markness, presented a summary of its report on the use of open source in France on 17 September in Paris. It is based on an on-line survey during in the summer months followed-up by interviews with 160 IT project directors, heads of procurement and other IT decision makers, half of which are employed in the private sector and the other half representing the public sector. Another fifty interviews were held with IT vendors.
Using open source requires firms and organisations to seek technical assistance and support, said 54 and 44 percent of the respondents. It also requires changes to their IT maintenance, said 38 percent. The research firm says that half of the respondents say that the current financial crisis is not a reason to switch to open source. However, to 39 percent this did make it more of an option. In 2011, open source will take up less than 20 percent of the IT budget of public sector institutes. Markness expects the French open source IT market to grow by more than 16 percent in 2011.
New users often feel overwhelmed by all of the new information they need to digest in order to confidently use Linux, and Hackett and Bankwell provides them a quicker way to get familiar with using Linux-based operating systems and master the material.
The publication is available to purchase here or you can make a donation which will help them to publish futher material, the comic is also available with Ubuntu on cd. This comic is suitable for all ages and has real educational value so by all means download the pdf and pass it on to younger readers, the illustrations are really fun.
Hackett and Bankwell can be instrumental in helping new users understand the various elements that comprise the operating system and how they work together.
