Fixing Ubuntu 14.04 Menus after 13.10 Fiddling Around

Dear Reader,

If you had used Ubuntu 13.10 and fiddled around with the menu settings you may have found that when you upgrade to 14.04 some of the menus appear odd.  Two things I noticed:

  • In Nautilus I found that the silly icons that replaced file menus were still there after the update but were not there in a fresh install of 14.04.
  • In firefox the menus were absent no matter what menu position that you selected in All Settings -> Appearance in the System Settings.

I traced the problem (after a lot of going around in circles) to the fact that I had tweaked things in Ubuntu 13.10 and this had unintended consequences during the upgrade.

So in 13.10 I had used this web-page: www.webupd8.org (or similar) to remove the appmenu-gtk appmenu-gtk3 appmenu-qt indicator-appmenu packages.

When you search in 14.04 they have been replaced with other packages – I searched and installed these manually and solved all my problems!

A quicker solution would be re-install indicator-appmenu and this should pull in all the dependencies that you need:

sudo apt-get install indicator-appmenu

Finding files by date using the GNU Find Command

So I have now acquired so many photographs (~20k) that Shotwell chokes a bit when I try to import more.  This is partly as I tend to let my memory cards fill up so it has to compare 2,000 photographs with the database of 20,000 to see if it already has any of them.  Still with my reluctance to delete anything means I need some GNU magic. 

find -mtime -7 -exec cp {} ~/Desktop/photoimport/ \;

Will find files in the current directory modified in the last seven days and copy them to the Desktop.  You can then copy them into the Shotwell directory and it is much quicker. 

 

Ubuntu 13.10 Review

So in order to get mdframed working in pdflatex I decided it was time to upgrade from the trusty 12.04 to something else.  So far this has turned out to be a mistake 😦  Let’s look at the pluses and minuses of the new distribution.  The plus points:

  • mdframed works as the Tex Live installation is much more up-to-date.  This does mean I have some of the world’s most pretentious handouts now:Screenshot from 2014-01-29 00:09:12
  • The Font problems I have been having with LibreOffice have disappeared and my Open Document documents look better!
  • the log-out boxes are larger

The negative points are longer:

  • Printers now magically appear – how do I know which is which?  I now have a list of every printer on the network….  Printing also seems much slower – but that might just be subjective bias on my part.  It also seems to be more flaky.
  • The menus have moved on a random selection of applications.  So Evince and Nautlius (now called files) have icons in the top right of the screen with a confusing array of icons from to click on like a monkey  whilst you search for things that have been in the same place since the 1980s!  I am not a fan.  This is Evince, what exactly is the difference between the spanner and the gears?  You have to click to find out!!!evince Screenshot from 2014-01-22 13:04:05
  • Nautlius has been renamed files and has a much poorer user interface.  The “Connect to Server” dialogue has been gutted and you now basically have to type in a command to connect to the server.  There is no longer support for the nice tick icon which shows you whether your files have been synchronised with Ubuntu One or not.  Finally the menus have moved to a selection of gears and arrows like Evince – expect they are are different so again you have to guess and click to see what they mean!nautlius Screenshot from 2014-01-22 13:03:36
  • The new interface is not particular consistent however – as gedit for example still has menus.  So as a user you are a bit confused about where to look for things.  Why this is an advance is a mystery for me – but I’ve never had much of a desktop vision.
  • Multiple desktops have disappeared.  This may not be a bad thing as the previous implementation in 12.04 was a bit buggy.  You can enable them quite easily and the when you do the bling factor has improved the desktop quite a bit.
  • I’ve also had problems with Ubuntu One synchronisation – but that might well be unrelated to the 13.10 upgrade.  There is now a much more meaningful widget thing that sits near the clock to control Ubuntu One.

Overall my impression is that the focus of Ubuntu has moved away from the traditional desktop onto touch interfaces.  I think that is pretty exciting but it does mean that there isn’t very much exciting going on in the latest release of Ubuntu and the current release lacks polish.  This is of course not an LTS release so I am looking forward to 14.04 where hopefully some of the rough edges will be knocked off.

Youtube Channel

Over the past few months I’ve put a few videos up on YouTube to complement the courses I am teaching at the small and well formed University where I work.  The following are my observations about this process:

  • The number of views of these videos exceeds the registration on the course by a considerable margin.  However speaking to the folk on these courses it is clear that they have not all watched the videos three or four times each, or if they did they don’t seem to have absorbed much of the material.
  • My production process is a bit cumbersome.  I basically use a microphone and record the screen as I talk.  I have an Ubuntu 12.04 setup at home and I use recordMyDesktop via gtk-recordMyDesktop 0.3.8 to well record my desktop and PiTiVi 0.15.2 to edit the videos.  recordMyDesktop is quite a mature tool (despite the version number) but PiTiVi appears to be progressing faster.  By cumbersome I mean dropped audio and being very awkward to chop off the bit at the beginning and end when you are reaching for the off button on screen.
  • The process is a real time suck – it takes a whole evening to produce a single five minute video.  This is because you end up doing it again and again to try and avoid making mistakes in your exposition.  I find you don’t make fewer mistakes as you go along at some point your standards just drop as you want to go to bed.
  • I’ve no idea if this helps or hinders student learning.  It seems to be popular but I think we need more this sort of thing in Higher Education.  Students like being given things – they like copies of slides, numerical answers, worked solutions, audio of the lectures etc. etc.  My personal view is that this is largely a waste of everyone’s time but without evidence either way this is just an opinion.
  • It does however provide a different sort of educational material.  I think it would be great to show worked solutions as you can add a live commentary to it and students can see how the solutions develops in a way you cannot with a static handout.  Of course I haven’t actually made a video like this yet – but it is on my list…..

I’ve Missed My Laptop

DSC_2062So after my laptop going technical I was left for three weeks without my computer!

Of course your laptop screen chooses to break on the day that you are giving four open day talks and you’ve lost the keys to your office….

O.k. so I took my annual leave right after that so I took my trusty Tablet S from Sony with me instead, thinking that this should probably be the future anyway. However I like the past for a few reasons:

  • I really missed my keyboard and my mouse.  I found the virtual keyboard slow and error prone and I missed the mouse as there is a clear distinction between position and action with my fat fingers I seem to often click buttons when I am simply trying to navigate around a page.  This can cause the odd outburst of swearing over slow internet connections when trying to enter complex data…
  • The Android Tablet pretends not to be a computer. This means the filesystem is abstracted away from the user.  This means it is much harder than it should be to do things like back up photographs from your camera.   To be fair a lot of software is doing this I often spend as much time looking for my boarding card download on PC as I did getting the PDF of the boarding card from the airline.
  • The Android Tablet doesn’t play DVDs.  When abroad I quite like to catch up with the DVDs that I have bought in shops but the stupidity that is region encoding means having a DVD player with an HDMI output is quite handy.  Messages like the one on the hotel supplied DVD player make me wonder when I don’t just pirate the stuff… DSC_2386
  • You need an app for everything.  Like navigating the file system to create a folder to backup your photographs…. but also for the stuff you do everyday like making notes, storing on-line passwords, creating a budget for the holiday, managing and uploading photographs.  Some of this could be solved by planning an preparation but as time goes on I want my IT to be simpler and simpler and only want to learn one program ever!
  • The Sony Tablet S has a really stupid custom power supply connector so you have to lug around a power brick and adaptor. Everything should be a standard supply in this day and age.  tabletspowersupply
  • Once you get back to mission control and want to copy files back to your computer your problems continue!  You connect the tablet via USB but then nothing happens…. This is down to the whole MTP thingy but still I had to had to check out OMG Ubuntu to get it done.

On the plus side my tablet is very easy to use on trains, planes and automobiles and comes with a game called angry birds where for no good reason I could determine a series of small birds (who looked angry) conducted suicidal attacks on pigs using a catapult and their own body weight.  Surprisingly fun.

Perhaps the future is actually in these touchscreen laptops which combine the best of both worlds…

DLNA Servers for Android and Ubuntu

When the family came to visit it would have be nice to see a few photographs displayed on the PS3. I still haven’t worked out how to get photographs from youface displayed in any meaningful way on the PS3. The web-browser is simply awful but the DNLA functionality seems relatively organised. Servers for various devices I have tried are:

  • For Ubuntu 12.04 MiniDLNA.  I pretty much followed the instructions at Dennis Conrad’s Blog but I kept the default installation file much more like the default.
  • For Android on a Sony Tablet S I used Pixel DMS.  To be honest I was pretty disappointed that a Sony Tablet can’t communicate with a Sony Games Console by default.  Especially when the Tablet is “Playstation Certified” whatever that means – clearly it doesn’t mean it supports a 10 year old standard (pioneered by Sony!!) for media sharing out of the box!  I’m sure that the fine people who make Pixel DMS are great and good but I don’t like installing random 3rd party binaries to get basic functionality sorted out.  However Pixel DMS appears to do the job just fine.

Whilst I am ranting on a bit here – one thing I really hate about Android is how it hides the whole concept of a file hierarchy from the user – this works great when stuff is auto-discovered but when you want to sort out backups or use a DLNA server that requires you to tell it which directory to serve up you then have to scrabble around trying to work out if you are or are not in the root file-system.
