The only reason why Linux isn't ready for prime time desktop

Okay, so this title's probably a bit misleading as there are probably a few reasons but as far as I'm concerned there's only one thing stopping my final transition to desktop Linux for complete every day usage.

Presenting

In my job I do a lot of presenting. I give major milestone presentations on projects, I present to the business on things that are going on, I present in pitches where we are attempting to win new business and recently I've started presenting at conferences.

I would not use my Linux desktop (and I have combinations of Ubuntu and KUbuntu 9.04, CentOS) to present with at all - even if someone paid me.

Before I say why I'll also lay out my Linux credentials. I use RHEL, Ubuntu and Centos EVERY day. All of my home computers are Linux based, I have a Linux PDA, I prefer my Ubuntu desktop for work and I administer numerous Linux (CentOS and RHEL) servers - via command line - all of the time. I've used it for over a decade and am more than happy with it and more than happy to hack on it to get stuff working.

However, there comes a point where I am not going to entrust a complete presentation that our business or my reputation relies upon to Linux's extremely flaky graphics system.

Yes, I know laptop Linux is problematic (but if the rest of the desktop is stable why not my second video out?)

Yes, I know that graphics card support (particularly from ATI) is very closed so there's lots of reverse engineering going on (but again if I can have one video out working why not two?).

I'm not sure why this is the case - I think it's a combination of X.org config and poor tools for configuring multiple screens with different resolutions but it definitely needs a lot of work to go ready for prime time.

I was at a conference this week and I had built my entire presentation in my Gnome desktop using FLOSS tools like Open Office Impress, had a great looking presentation and was legitimately keen on presenting using either my Ubuntu or Centos desktop. After hours of mucking around however I didn't feel supremely confident in just walking up to the podium, plugging in my laptop and "It Just Works"^TM. It's just too hit and miss.

I don't generally experience this with Linux in general and Ubuntu specifically although I am aware of other people saying it. For me 99% of the time it does actually just work.

So I defaulted back to my dual-boot Windows partition and presented from that instead. This was the partition that I had considered nuking because I hadn't used it in about 6 months. In this instance though I didn't have any other choice - and sure enough it did just plug in and go.

I still presented from Open Office Impress though (which is a fantastic bit of software I might add!) and I think I was the only one at WDS09 that presented with it (and I'm sure no one could tell I wasn't using PowerPoint or Keynote).

Desktop experience is exactly that - an experience and our experience, particularly when we are doing something social with a computer can affect our mental state quite substantially.

If I'd have taken the decision to present using Ubuntu I would have felt worried about whether my laptop would work and I would have been nervous and probably would have delivered a terrible presentation. In contrast because I knew I wasn't going to have any support issues I felt confident, in control and delivered what I hope was a good presentation to the audience.

Ubuntu are trying to address many of these issues with the Paper Cuts project but that's really aimed at business. Apple have addressed similar issues (hardware compatibility) by having a presenter's kit (which you buy) which provides all kinds of adapters to go from Mac to just about every video input type. Microsoft addressed this years ago from Windows 2000 with a great set of dual head tools that made it simple and a standardised way for vendors to incorporate them and it is extremely rare for it to fail.

Business use is one of the areas that Linux (and especially Ubuntu) has got a real opportunity to shif users across as there are so many other business benefits but users want a single consistent desktop so they aren't going to build on one desktop and present on another - it's too inconsistent.

For me this issue on presenting and graphics support isn't so much a paper cut as it is a gaping flesh wound and it really needs to be addressed.

EEEPC's power is in the network not the machine

Over here at Technology Treason we lurve ASUS' EEEPC. We liked the idea when they first came out and specifically trawled around Hong Kong computer markets to find one not long after they were launched. It's not the Apple Air or iPhone kind of aesthetic lust, we're talking about true "in sickness and in health" type love when it comes to the EEEPC.

Indeed for someone to now take this device off me it really would have to be from my cold, dead, rigamortis set fingers - and then only with a saw.

Go online and look at reviews. They fall into two camps - those who think it's great as a second machine that just happens to do a lot of funky things (see latest Linux Format June edition for a classic example) or those that just don't "get it" any wonder why the hell anyone would want a tiny-weenie machine when you can get a low spec dell for a few hundred quid now.

There is third camp however who are starting to realise that a linux based UMPC is truly a brilliant bit of kit and it's really because of the network it sits on not the thing plugged into it.

I've had mine for about 5 months and realistically I've installed about half a dozen bits of software - 10 at a push. I can do docs, review spreadsheets, skype, web browse hell even play games if I want and when hooked to a network I can do all of these things with all of the files I could possibly want.

My machine comes home and it auto connects to my home network, synchs to my media server and can play all my media files out of the box. I can check my mail and actually read it without squinting without firing up the laptop. I can connect from home to work via a VPN and mod some files for a client without leaving the sofa or the garden and be doing wht I want before the laptop has finished booting to a desktop.

At work I can use it for presentations and taking notes on projects without printing stupid amounts of documentation and hefting my laptop along with me.

It's not a replacement computer - it's a tool. A finely shaped, infinitely configurable tool. All the things I want in my phone but will never get because of the lack of keyboard,mouse and processing power and without it being much bigger.

The thing is I'm a techie, if I'm talking a walk down the street phone and wallet are it. If I'm going somewhere then it's satchel with camera, book, PSP and now EEEPC in place of a laptop.

ASUS have released details recently of a new version designed to hit off the people who think the other is too small. I don't know myself. Small is beautiful and in this case perfectly formed.

Ubuntu 8.04 - truly desktop Linux

I'm quite an Ubuntu fan, having followed the project since more or less it's original inception. Given the general lack of problems with it thus far you'll notice very few entries on this blog about it.

Indeed various clients of mine are running Ubuntu servers that are easily maintained, easily managed and just generally easy and have been for several years. It's not necessarily an industrial strength OS - see Fedora for example - but for quick deployment, great security and stability and a modifiable tool (thanks to its Debian base) that just gets the job done you don't really need to look much further.

But I think that's about to change. You see Ubuntu 8.04 (the latest version that also happens to be a Long Term Support version) has markedly shifted the goalposts of what I expect from a Linux distribution.

I've been wanting to be convinced to move to a complete Linux desktop for the better part of 10 years but there's always something holding it back - lack of support for a media type, lack of drivers for particular bit of hardware, issues to do with wireless, no power management for my laptop, I can't run some third party apps like Skype... but that has all now changed - and changed in a massive way.

As I'm want to do, every time a new version of Ubuntu comes out it is duly installed on my Acer Travelmate notebook - a very good test of whether an upstart OS "just works" or not. The machine is about 2 years old but it has some quirks such as it has an ATI 3D card embedded on it's motherboard that was difficult to get working properly even on XP, it also has an inbuilt webcam - again with proprietary Acer drivers and it has gigabit Ethernet. Oh and it's widescreen.

About 9 times in 10 I don't even get to a working desktop without some hackery of graphics drivers, x.org files and I've even had a couple of "bomb-proof" distros just not even boot up to a command line.

I've been around Linux for a long time and I know what to expect, I'm an enthusiast and advocate so none of this surprises me at all and I'm prepared to work through the issuses. Most of the time I get to a working desktop with some sort of graphical interface that is mostly not widescreen, with no 3d support, sometimes wireless and without the use of the webcam. Linux isn't aimed at desktop use - it's just a side effect of people using it for development who wanted some creature comforts whilst working - notably the Gnome and KDE bods.

Imagine my surprise when I booted Ubuntu 8.04 and I logged into a graphical desktop that detected wireless and gigabit ethernet, properly displayed my screen in widescreen mode, gave me the option to run my ATI drivers easily and then configured the 3D in a few seconds and on top of that gave me a working webcam that I'd never had running under Linux and you could tell from the whoops of joy that here was something worth formatting my hard drive for.

Every device I threw at it was auto detected and installed in moments, flash drives, USB devices, a weather station, even an old MP3 player than needed proprietary Sony software to synch on XP. All handled with aplomb and with scarcely a pause by the processor.

What the hell was going on? How did we go from solid and okay 7.10 to this awe inspiring 8.04 in just six months? Had Mark Shuttleworth finally given his soul to Beelzebub in exchange for the most promising distro to date?

Then the answer came to me in a word: Vista.

Vista - that problematic and misbegotten child of Redmond that has been causing havoc in the IT world for nearly a year now. I haven't installed it on a work machine, neither has any other techie I know that wants to "Get Things Done". My dad had it and tried it daily for 6 months - he's now back on XP. I know corporate users who've had it on new machines and reverted to XP in order to decrease the amount of support required for users.

Shuttleworth and his cabal of Elite Ubuntu coders have recognised a change is in the air - particularly in Europe that is Linux's stronghold - we have an opportunity to put Linux on the desktop of millions of users who might upgrade to Vista but are worried about its impact. Couple this with a slight economic downturn and people are worried their existing hardware just won't work with Vista thus leading to a higher upgrade cost.

This latest LTS version gives novice and power users alike the ability to do anything they want with their desktop and it just works. It gives corporate users the knowledge that they have the security of support for 5 years without the rug being pulled out from under them.

We bit the bullet this week and put all our support team onto this version exclusively - WinXP was nuked off their machines. The development team are all dual booting but the number of XP desktops seem to be fading from view at a very fast rate as the requirement to just "drop in" on Windows becomes less necessary.

We've been saying it for nearly a decade but "this year is the year for desktop Linux" and with 8.04 Ubuntu the excuses for moving OS can now be left at the door thanks.

The state of Oz technology

Well rarely does an entire country entice me to start ranting (and at this point I'll point out I am in fact Australian) but by crikey Australian technology hasn't really moved in the last 5 years.

Now I appreciate this is a sweeping statement and I'll point out that the technology I'm talking about primarily is media based - mobile / web / internet. I have also had the benefit of living in London for the better part of 10 years so I've been at the hub of what is going on.

What I don't understand is why is it that for a nation that was at the forefront of new media ten years ago are we now in a position where nothing has shifted for the last 5. SMS is still massively underutilised and the idea of an SMS shortcode in Australia is a joke - 8 digits is only 2 shorter than a mobile number so is hardly short! Indeed everything to do with mobile is still more expensive, slower and less polished than we are used to in Europe. I went to Vodafone when I got here and asked for a pay as you go sim card for my phone that had pay as you go data on it... I was met with blank stares - Telstra and Optus were both the same.

General Internet access is similarly expensive and slow compared to what we are used to in Europe. Given a relatively modern telecommunications infrastructure, why telcos are flogging the ADSL route instead of fibre / cable begs the question of why so many roads were dug up in the capital cities to facilitate this in the late 80s and early 90s.

What is also interesting is the lack of FOSS out here. Linux is relatively popular but no where like it is in Europe. Indeed corporate America has it's laser telescopic sight firmly trained on the Australian market and even getting Linux hosting is no where as simple as getting a site hosted on a windows server. Linux certification and knowledge is still seen as a specialist skill.

Overall I'm disappointed that Australia hasn't maintained it's lead in internet technologies. In part people like me are to blame for starting our careers here and then being drawn to the brighter lights of the UK and the US where visas are easily come by, pay levels are higher and the ability to work on cutting edge technologies are plentiful.

Perhaps we are on the verge of a change in Australia and I hope that some of the ground lost can be regained over the next five years.

Adding Cron Jobs to a QNAP server

If you haven't come across them yet QNAP make these amazing little NAS boxes that are perfect for home or SME use. I've got mine running as a home server but might get one for the office as our old server is on it's last legs and a fully tricked out 1U dell server is a bit of overkill for a glorified file server.

The best thing about these devices though it that they run Linux OS utilising Debian Essential and as such they can be configured to do almost anything you want. Out of the box they already come with file serving, media serving, database and web servers.

One slight problem though is that the boot up process is not disimilar to that of a live CD. This is great in that it makes the system highly robust and it boots to a known state each time. The problem is that short of rewriting the firmware you can't introduce things into the boot process. What I don't want to do is have to re-run a load of scripts to configure the server how I want it after a power failure or forced reboot.

The boys over on the QNAP forums are really on the case and one of the chaps has created a nice little framework script which hooks into the boot process and allows the execution of a series of scripts. You can see his work here.

After installing this workaround you can add scripts to the scripts folder and take control of your server.

One of the things I wanted to do was add items to my cron list and this process is explained below.

1. SSH into your QNAP box

2. Install the custom scripts files at http://www.qnap.box.cx/ as per the directions there.

3. CD to your scripts directory in custom and make a file called joblist.txt in VI (Vi is the only editor you have on the QNAP drive).

# vi joblist.txt

When in vi make your list of cron jobs using the standard CRON syntax.

Mine was the following:

25 1 * * * /share/backup/script.sh

This will run a backup script I had written at 1:25am everyday. You can add as many or as few as you want. Save your document and exit from Vi.

4. Make your script that will fire on start up. I called mine cron_update.sh

# vi cron_update.sh

In there put the following code:

#!/bin/sh
# this script apprends a job list to the existing crontab
echo "Reconfigure CRON list:"
cronpath=/share/MD0_DATA/custom/scripts
#list the cron tab and put in a temp file
crontab -l > $cronpath/cron_jobs.txt
#append the items we want to the master cron jobs list
cat $cronpath/joblist.txt >> $cronpath/cron_jobs.txt
# replace the existing crontab with the new one
crontab $cronpath/cron_jobs.txt

Save and quite out of Vi.

You'll notice I've used a variable in here to specify where to find the files. This is because the autorunmaster script is a folder higher so we need to be explicit about where to find things.

5. Go back up a directory to your custom folder. In there edit your autorunmaster.sh file with vi.

# vi autorunmaster.sh

At the end of the file append:

/share/MD0_data/custom/scripts/cron_update.sh

Then save and close the file.

Now when you reboot you should have your newly added cron jobs appended to the crontab without removing all the old ones.
