Joe Liau: Dumb is Dead: Snappy is the New Smart
Once thought to be a “smart” device, the dumb telephone is now a thing of the past. But, if we look closely we might see a hero arise from the ashes:
Ubuntu could truly save our phones, and it’s up to us to make sure that it happens. It’s fun to dream up ideas, and it’s even more fun to contribute towards seeing those ideas in action. We can then start to see these dreams become a reality. We can make things better, and we may even see some truly smart devices. Or, is “smart” now a thing of a the past as well?
I must say that “snappy” was never part of my personal lexicon, but I think that’s why it will be effective. There’s no baggage attached to the word. Just like we have seen a departure from “loco“, we can start to move away from other concepts of the old world and begin to create something fresh. Ubuntu has always about being a positive change rather than another flavor of the past.
Let’s continue to make Ubuntu this way. Stay snappy, my friends.

Ronnie Tucker: Dota 2 Runs Natively on Mir with the Same Performance as X11
Canonical has been working on the Mir display server for some time, although most of their efforts have been made towards the mobile platform. They are now looking to optimize it for desktop use and nothing reflects the progress made more than a famous game running on Mir.
Mir is already working on the desktop, but users need to have the open source video drivers in order to make it work. Canonical has recently built a new flavor called Ubuntu Next which features Unity 8 and the Mir display server. The new desktop environment needs Mir, so it stands to reason that the updated DE will arrive for regular users when Mir is also ready. It’s not there yet, but it’s taking great strides.

Colin King: Controlling data flow using sluice
Earlier this year I was instrumenting wifi power consumption and needed a way to produce and also consume data at a specific rate to pipe over netcat for my measurements. I had some older crufty code around to do this but it needed some polishing up so I eventually got around to turning this into a more usable tool called "sluice". (A sluice gate controls flow of water, the sluice tool controls rate of data though a pipe).
The sluice package is currently available in PPA:colin-king/white and is built for Ubuntu Trusty, Utopic and Vivid, but there the git repository and tarballs are available too if one wants to build this from source.
The following starts a netcat 'server' to send largefile at a rate of 1MB a second using 1K buffers and reports the transfer stats to stderr with the -v verbose mode enabled:
cat largefile | sluice -r 1MB -i 1K -v | nc -l 127.0.0.1 1234
Sluice also allows one to adjust the read/write buffer sizes dynamically to try to avoid buffer underflow or overflows while trying to match the specified transfer rate.
Sluice can be used as a data sink on the receiving side and also has an option to throw the data away if one just wants to stream data and test the data link rates, e.g., get data from somehost.com on port 1234 and throw it away at 2MB a second:
nc somehost.com 1234 | sluice -d -r 2MB -i 8K
And finally, sluice as a "tee" mode, where data is copied to stdout and to a specified output file using the -t option.
For more details, refer to the sluice project page.
Riccardo Padovani: Ubuntu Phone seen by my friends
Some days ago OMG!Ubuntu announced the date of the release of first Ubuntu
Phone. That night I was in a pub with some friends, so I told them about the
release and the price of the phone.
All my friends present that night study in universities not related to tech, or
technologies. They know about Ubuntu only because I’m involved.
So, they wanted to try the system, and I was more than happy to show them my
phone. It’s a Nexus 4 with RTM #12, and I use it as everyday phone, so it has
lot of apps and stuffs on it.
All feedback were more than positive, mainly on two topics:
- Fluidity: compared to a phone with Android 2.x (yes, there are some phones out of there with this old version of Android, sometimes it’s very interesting how is technology out in real world)
Ubuntu on Nexus 4 is very very fast, and the same speed is on the BQ phone
that will be sold in February (I tested it a couple of months ago, and it is
- Multitask: the right to left swype gesture was greeted by applause. It
is fast, cleaver, simple, and everyone wants it on every phone. Also other
gestures were appreciated: after some minutes to understand how to go back
(our brains are used to a physical button at the bottom) all guys seemed
accustomed. But multitask was the most acclamate gesture, seriously
Not all is so good, there are also two negative feedback:
- Unlock screen: all my friends tried to unlock the phone doing a circle
with the thumb, and all were disappointend to find that is needed a swype.
There is a circle in the center of the screen, why do a swype?
- Whatsapp: unfortunately, all them said won’t consider to buy it until
Whatsapp arrives. I know it isn’t an Ubuntu fail, but Whatsapp was the most
Anyway, I’m more than happy with the results: Ubuntu Phone seems ready for all,
and this is a good point where we could start to build. We have simply to
continue on that way, and we will change the world, bit by bit, mind by mind.
Here my friends try Ubuntu on Nexus 4:
