Review of Sugar (SOAS) Operating System

What is Sugar?
SOAS (Sugar on a stick) is the free easily accessible Operating System by Sugar Labs which is being used for the One Laptop Per Child initiative. SOAS is free under LGPL & GPL license. SOAS is downloadable from http://www.sugarlabs.org/

What have Sugar labs tried to do when creating sugar OS?
Simply put, create an operating system for learning. This may or may not be the correct way to introduce a child to computing. I cannot be the descision maker of that due to my lack of experience but I can give you an insight into the performance from a usability point of view.

The (Home page) for a pupil

How smooth is the OS?
Very smooth, everything is pretty obvious, within a few seconds you are up and running, browsing and/or learning. Websites such as Primary Games Arena (Flash) and School Email (Microsoft Exchange OWA) work great. The browser home page is a bit boring and maybe Primary School Safe Search should be used as an alternative.
Changing from one application to another is seamless, although you can’t keep many applications open. I couldn’t find the option to shut down, I guess it was hidden..
Come on John, you can’t convince us that an OS on 256 MB or ram runs “smooth”!
I didn’t think it would myself but it does, mostly due to the fact its a clean boot up every time and there is no ability to store lots of stuff in swap space to slow things down!
It can’t be all gravy and chips!
I found the scroll bars a little too small for young kids and I worry about the black and whiteness of the GUI. It’s clean but is that what kids want? From experience, no..
An activity.
Structured Learning..
One thing the Sugar OS tries to do and I’m not convinced that is succeeds is give the pupil some sort of structured learning, by providing reading materials then activity’s based on the material. I guess they think that teachers will create activity’s but something tells me this may be a pipe dream.. I may be wrong though.. These activity’s are also confusing me because some of them just don’t open anything, I get a grey screen. I guess this part of the OS is work in progress..
Applications such as Joke Machine just seem to lack any true obvious structure or examples (probably due to restrictive disk space) but seem to have a great deal of potential for more experienced Sugar users.
Overall review
A very good operating system for learning at school and away from school. Fulfils all the requirements for a great mobile OS and seems quite engaging. My only criticism is the lack of spark on the GUI, the GUI is just too flat for me and needs some funking up!
Would I use it over Windows 7 in a school?
Well, a Windows 7 powered Asus EEE device is going to set the school back £300+ where as a Sugar device should cost £160 (all maintenance taken into account on both OS’). If money weren’t an object I would stick with Windows 7 but if it means we can give 2 pupils a device instead of 1 then the One Laptop Per Child initiative wins hands down. Sugar’s educational focus puts it ahead of other open source OS projects and even hosted cloud OS’ as it provides always available learning.
Just don’t tell my Microsoft buddy’s about this post 😉

Installing Sugar (Soas) onto Windows Virtual PC 2007

Sugar won’t install by default. I have tried hitting tab and adding noreplace-paravirt to no avail 🙁


This is a screen dump of what I have..


Adding add vga=0x32D will boot me into the GUI but I have no mouse!

Adding i8042.noloop gives me a mouse!

How to do it:

  1. Create a Virtual PC
  2. Set RAM to 256MB
  3. Mount Sugar ISO image
  4. Start up your Virtual PC
  5. A message will pop up saying “Automatic boot up in 1 second” – Hit TAB!
  6. You will see a line saying “vmlinuz0 initrd=initrd0.img root=CDLABEL=Soas2-200906221314 rootfstype=auto ro liveimg quiet rhbg”. Remove the last 2 words (quiet and rhbg)
  7. Add “vga=0x32D i8042.noloop” to the end of the line
The line should read…

vmlinuz0 initrd=initrd0.img root=CDLABEL=Soas2-200906221314 rootfstype=auto ro liveimg vga=0x32D i8042.noloop

*Note the CDLABEL value may change dependant on the release you use!

**Note Files will not be saved in this version, there will be no persistence so updates will not be saved either. This is not the case if you boot from a USB Key

Congrats – Working Sugar on a virtual PC 🙂

How you can help the 1 laptop for every pupil scheme

Uruguay just give every primary school pupil a laptop. This was only possibly by kind donations of USB memory sticks to Sugar.

Sugar is the operating system that runs on the devices, it is bootable anywhere from a USB stick. The USB memory stick doesn’t need to be large, 512 megabytes is plenty!
Please send your used USB memory sticks to http://recycleusb.com and they will turn them into Sugar sticks ready to be used by children all over the world!
