Jono Bacon has announcedthat LUGRadio Live 2009 is happening and the basic website is now up and available. So for all that have not heard about LUGRadio Live before, let me give you a brief overview.

LUGRadio Live was a spin-off of the successful LUGRadio podcast, the guys decided that there was no decent open source conferences in the UK so decided to setup their own. The conference is in its fourth year, even though the podcast has finished. LUGRadio Live is described as a “rock conference”, everything is light-hearted and easy going but it attracts some big speakers right across the open source community.

If it sounds interesting, checkout the website, register your interest on Upcoming or Facebook, and follow the Twitter or Identi.ca users.

My name is Andrew Williams, and I used to be a Webmin user.

During the last year or so, I’ve used Webmin and Virtualmin to manage my VPS hosting. For those who don’t know, Webmin is a web based server management console built on Perl, it allows each service to be managed by the use of modules, which you can install/uninstall to create a customised interface for your machine. With the addition of Virtualmin, the Webmin interface becomes a virtual hosting console much the same as Plesk or CPanel.

Webmin has a murky past, several high profile exploits existed for the system and it’s been advised for the last 10 years or so not to install it unless you really need to. Giving world access to Webmin was generally advised as stupid and silly. While Webmin is now up to date with it’s security it still leaves a bitter taste in the mouth of the administrator world and people who use it are usually noted as “newbies”.

I originally went with Webmin/Virtualmin as I was still hosting the few remaining customers of Blueshift Media. While I have the technical skills to work without it, the customers didn’t. The system gave a simple interface for the users and allowed them to add in basic stuff like new email addresses and aliases. To work around the security issue I only allowed access via SSH and port tunnelling, that way the user would have to be authenticated with the server before accessing the system. 

Over the next year or two I started using Webmin to do my daily administration tasks, as working outside of Webmin once it’s installed can open you to a world of pain, Webmin keeps track of some configuration in it’s internal database, not in the external configuration files. Over time I become comfortable with the system and my technical skills slowly slip away from me, why do I need to know the in and outs of a program if Webmin can do it all for me?

Today, I learnt the hard way. I had a issue with Postfix content filters and I spent 10 minutes faffing in the Webmin console only for it to be a five second fix in the main.cf file. In a further similar fault I had to read up on Postfix Virtual file format as I’ve totally forgot how it’s supposed to be formatted, somehow the file had got munged and I had to reconstruct what I could.

Then it clicked.

Since I’ve installed Webmin I have been wrapped up in cotton wool, not actually touching the underlying the system and just using this fluffy interface to do my work. This is all well and good in the desktop world but in the server world your risking security and your knowledge of the underlying system.

So, today, I’ve officially removed Webmin, and I’ll never to return again. It’s time to actually learn my trade again and start using the distributions as they’re meant to be.

A month or so ago, Phillip Newbrough of the CrunchBang Linux project made me a IRC Operator in the offical support channel, #crunchbang on Freenode. During the last few weeks the IRC channel has exploded with popularity, from a low average of 5-10 at the start of January, the channel now idles at around 35-45 users.  This is a massive improvement over the course of a month.

With the influx of new users come a influx of new trolls, every channel has them, every channel loathes them. Unfortunately #! has not been exempt from this. It came to great shame when within the first few weeks of the channel getting popular we had to ban our first user. Banning is a last resort in my eyes, and in the case of this user he was disrupting the channel and offending numerous other users. Action had to be took, and now that user is serving a one week temporary ban.

So, what can we do to avoid this horrible situation? The times when it’s the trolls vs. the operators, the back and forth can alienate new users and turn other users against the established operators. This provides a very difficult situation for anyone to handle, and something we want to avoid in the channel. So, In response to the rapid growth of the channel we’ve picked a few new operators, people who we trust, and while they’re not seasoned IRC users they show the level head required to take on this role. In addition to that we’ve took on a new rule set to clearly define the boundaries of the channel, Now the users and operators will understand where the buck stops and know clearly between right and wrong on the channel.

So, what next? Well, we’re still in the process of guiding our new operators in the way of IRC moderating, this will take time but hopefully we’ll come out with excellent results. An addition to the logging bot (Scribbler) will allow for “incidents”, that is, kicks and bans from the IRC channel, to be reported to the correct people. We are clarifying our complaints procedure, for people who think they’ve been kick/banned unfairly. I’m sure you’ll get to hear more details as times go on, and I’ll even post some specifics in the near future.

It’s that time of the month again, Liverpool LUG has snuck up again and it’s time for me to post the details.

Liverpool LUG Meeting
4th February 2009 @ 7:00pm
Liverpool Social Centre, 96 Bold St, Liverpool, L1

This month is a little different, thanks to the Liverpool Social Centre we have a meeting space available to use for this and future meetings.

This months talk will be given by Vladimir Jakubovskij and is regarding his recent research paper “Open Source perspective: The current situation with online music piracy and the future of free music distribution”. Vladimir will be discussing the topics in his paper at the talk. The paper will be published under the CC license at a later date.

If Vladimir is unable to give the talk for some reason or another, Then Joanne Roberts will (hopefully) have a quick talk devised on Open Street Map.

This will be our first meeting at the Liverpool Social Centre on Bold Street. Access is currently through the door next to the News From Nowhere bookshop entrance. Ring the doorbell (the small white one to the left of the main buzzer) for admittance. If you have any difficulties finding the event, please call 07530 709 263. I’ll be in Liverpool quite early to make arrangements and organise things.

Afterwards, we’ll head to a local drinking hole for a few off topic drinks and banter.

The Liverpool Social Centre is a non-profit volunteer ran operation who usually charge for their space, but they’ve offered this location on a free basis in return of support for their compute cluster. For the first month it would be good to give a small donation of £5-£10 from the group to cover costs, so if you could bring 50p or so to donate they would appreciate it. For more details about the location check the website.

Hope to see you all there

On an additional note, I’ll be there with my Tikitag reader and related software to show off my pyTikitag stack for reading the tags in Python and also to generally fool around with them.

Over the last week or so I’ve become quite involved in the CrunchBang Linux project, I got picked up as a forum moderator and it has spiralled out of control since. I’m now a forum moderator, IRC channel operator, and a administrator on the CrunchBang Launchpad groups.

Crunchbang is quite an interesting project. A small distribution created by one man, Phillip Newborough, which gained almost overnight fame and is now ranked quite highly on Distrowatch. The speed of the success of CrunchBang is a massive achievement, especially when you take in the “youth” of the project. While i’m not the official biographer of the project I can see a few key stages that helped it gain such a strong following in a short time.

In the recent history of the project, fabsh, also known as Fabian Scherschel of Linux Outlaws fame, decided to give the distribution a go. It seems he instantly fell in love with it and recommended it to everyone via his identi.ca feed. During the next episode of Linux Outlaws, Fabian mentioned the distribution and how he has been trying it out. The result was a large spike in people downloading the install image and signing up to the forums, this was the time where I toddled along and discovered it myself.

Fast forward two weeks or so, and Distrowatch adds CrunchBang to their listing, a minor but important win in the expansion of the distribution, the DistroWatch listing brings in more and more people over time. Just after Christmas the 8.10.02 release was let lose and Distrowatch was one of the first sites to get the news out there. As the release was done over the relative quiet time of Christmas, the release note spent a good few days on the front page of Distrowatch. Over the Christmas period the forums saw a large boost in signups, which are usually a good indicator of how many people have downloaded the distribution.

So, the combination of a major Linux podcaster and reputable distribution news source gave Crunchbang it’s push into the limelight. What the last few weeks prove is that a few key figures could boost the popularity of a good product and take it from small time to the big time in a matter of weeks.

So, how is this applied to other projects?

First of all I think the key success on CrunchBang’s part is the product itself, a lightweight desktop environment, based on Openbox, designed for the power user crowd. A few people had mentioned that this was the type of area that Arch excelled in, but now the user had the convenience of Ubuntu to their Openbox desktop.

Second, the recommendation of trusted peers can only boost the popularity. With the “social media” that exists today a few trusted people could push a project from a bedroom to the stage, so to speak. With tools like identi.ca and Twitter, people have rapid methods of posting their thoughts. The social media can be a double edge sword, as quickly as your software is recommended it could be bashed and ridiculed just as easy. So, in my opinion, this can make or break your project.

Third and final item is the existing “web media”. Blogs and sites like Distrowatch, Slashdot, Engadget and other tech sites allow, again, for trusted people to review and make judgement of the project, a good recommendation will boost your users and a major site such as Slashdot will kill your server if your not careful.

So how does this all relate to the big bang? It doesn’t really; I thought the title would be snappy.

It’s a rare occurrence that I post about Liverpool LUG and the meetings, as I thought a few people are not signed up to the mailing list it’ll only help to post it elsewhere. So to save rewriting what has already been posted, here is the original notification email.

Liverpool LUG Meeting
7th January 2009 @ 7:00pm
The Bar, 1st Floor, FACT, 88 Wood St, Liverpool, L1 4DQ

It’s coming up to that time of the month again, as it’s so damn close to new year I think we’ll keep it as a social night, unless someone wants to step up and give a talk.

As per usual, we’ll start at FACT and move on to another place if we feel the need to. We’ll be located in the Bar on the 1st Floor outside Gallery 2, keep an eye out for UMPCs, beards, and a plushie Tux. If a talk is on we’ll usually move from the bar to the conference room at about 7:15pm, if you arrive late you can get to the conference room via the lift (head to the 3rd floor) or if the lift is disabled ask a security guard.

Hope to see you all there

 If you’re thinking of heading down and not sure of the location then drop me a email, I’ll be getting into Liverpool at about 6:30pm at Liverpool Lime Street.

A while ago I spotted a post about a new Ubuntu based distribution that had been released, called CrunchBang Linux, as i’m not a great fan of Ubuntu distros anymore I passed this one up and never look at it again. A few weeks had passed until I heard mention of it again, Dan from Linux Outlaws, mentioned that he is trying out the recent version for a review on the show and that Fab is a massive fan. I decided to take a second look at it, trying my hardest not to be critical due to it’s Ubuntu base.

I’ve now got CrunchBang installed on my main desktop machine and I’ve been using it for a day, Maybe it’s a short length of time to review a distribution but I feel with my past experiences with numerous distros will help me get to grips with a new one quite quickly. Some of you may know, after being a Ubuntu user for well over a year I decided to move back to Debian and became quite critical of Ubuntu for its rash decisions regarding design and key choices. My dislike is not centred purely on Ubuntu, I remember one time where I had a near fit at using a OpenSUSE KDE 4.0 Live CD as I couldn’t switch off the default sound scheme, but that’s for another post. Back to the review…

CrunchBang Linux promotes itself as a lightweight version of Ubuntu, unlike Xubuntu’s XFCE desktop they’ve decided on using OpenBox and a few key programs from other desktop environments, like Thunar and Lxpanel.

My previous experience of the *box window managers have been with Blackbox during the very early days, when Enlightenment was all the rage and most distros used FVWM95, so checking out Openbox will hopefully be a refreshing blast to the past. My main concern was compatability, a lot of applications out there depend on certain features of the desktop environment. I left all my expectations at the door and decided to grab the Live CD and have a 10-15 minute play to see if everything works as expected and that it actually works on my slightly quirky setup.

The Live CD / Installation media is mirrored on a few sites, as it’s only a “baby” distro it’s not been picked up by the mainstream mirrors, thankfully, a few people in the community had offered some space up to the project and finding a local, fast mirror isn’t that difficult. As with all Ubuntu style Live CDs, it was a simple case of burning the ISO to a disc and rebooting the machine. I’m not sure if this is a feature of all new Ubuntu discs now, but the ISOLINUX menu had a option to check the installation media for errors, this would save you quite a bit of time if you suspect dodgy media.

The boot was quick, quicker than I expected. Usually with Ubuntu CDs I pop the disc into the drive the slip off to make a cup of tea and head back in time to get the last second or so of the desktop booting. This wasn’t the case with CrunchBang, after returning from a delightful brew making trip I noticed that the desktop was loaded and the default conky panel on the right side informed me that it’s been booted for about 5 minutes. So, boot speed, even from the CD it’s nice and quick.

To a user who has been brought up on the GNOME or KDE environments the initial desktop may take a second to sink in, by default it comes with a minimal panel and system information pane on the right side of the screen and nothing more, no desktop icons or fluffy applications menu, just a basic desktop. Right clicking anywhere on the desktop brings up the system menu and the list of applications. The default install gives you a nice range of applications, some you’ll never use, others are dire essentials.The default includes a few keynote applications:

• Firefox 3.0.4
• Pidgin 2.5.2
• Rhythmbox 0.11.3
• Skype 2.0
• Gwibber 0.7.2
• GIMP 2.6

A few more are available, and a full list can be found on the CrunchBang wiki. Needless to say I was impressed, not only had they selected reasonable defaults but as the distribution is based off Intrepid it had the latest and greatest versions available. Skype is a interesting nugget in my opinion, possibly being the only QT application in the default installation. I do understand that lots of people use Skype for VOIP, but maybe they should consider including another application like Ekiga.

So, I have my desktop running as a Live CD, time to see how it fayred in real world usage. I can happly say, after a good hour or so usage I didn’t feel restricted by the choice of desktop environment, Openbox is low key but quick and powerful. I decided after just a few hours usage to commit to this distro, ditching my current Debian Lenny install.

The installation of CrunchBang was nothing really spectacular, It’s a standard Ubiquity installer which does it’s job very quickly. A few quick selections and the dreaded disc paritioner screens and you on your way. Installation took about 10 minutes on my machine and felt a little quicker than previous Ubuntu installs, but I put this down to a little bias on my part. Rebooting the machine brought up a standard GRUB menu and I happly noticed that it detected my existing Windows installation and put the relative entry in. Again, the boot was quick and my machine boots to the desktop in under a minute.

So, here comes the negatives. A few minor issues have bugged me since i’ve started using CrunchBang, but nothing show stopping. So to save time I’ll just put them down as bullet points:

• xcompmgr seems to have a “dicky-fit” after a few hours use, making all window focus go out of the window. Disable/enable of Compositing fixes that.
• Tray Icons are hit and miss to what actual colour they use for their background. In my case with the “Fawn” gtk theme you get either a brown or beige background, which looks a little messy. Not really a distribution problem but still annoying.
• Restarting Conky seems to paint over the entire desktop for no reason, causing the Windows-esq issue when you have to use an existing window to get the desktop to repaint.
• By default, the xserver won’t detect 1280×1024. Simple fix of modifying the Xorg configuration but initial boot of the Live CD can be annoying with a mishmash resolution.

As I said, the negatives are MINOR. Really, really minor. CrunchBang was designed as a “2nd - 3rd” distribution for users, so it targets the section that are more than happy to have a twiddle with the system configuration and the thought of text only configuration doesn’t phase them. If you fall into this category and you’re looking for a lightweight desktop distribution then i’d suggest you grab a copy of CrunchBang and give it a whirl.

So, I finally got round to giving a talk at LivLUG, anyone who knows me will know i’m not the best public speaker in the world and I get quite nervous at the thought. It was time to grab the bull by the horns and actually do it!

My first talk was on the usage of the Wiimote within Linux, The Wiimote are very simple Bluetooth devices that can be accessed over the standard APIs with an additional library called CWiid. This allows the device to be used as a input device or as a general I/O device.

It’s quite hard to explain it in just text alone, So i’ve put my presentation on the LivLUG wiki everyone to have a look at. I recommend you grab it and give it a try yourself.

EDIT: Yes, It’s on the wiki now, but heres the direct link.

A little late, but still interesting. Google has announced that the source for Android is now available. Google have kept up their end of the bargain and the source is out there for all to view, it’s a interesting prospect with the G1 release just around the corner. I know that quite a few hackers out where will be tinkering with Android for the next couple of weeks, maybe even have some interesting developments for the G1 launch.

Now that the source is out there, I wonder what the response the other platform developers will have. I suspect Nokia/Symbian to play down Android’s place in the market and RIM to wave away the benefits of open source. I have to wonder, HTC are releasing the G1 and now Google has released the source. Will users be able to flash update their version of Android? Or will they be bound to the operators/HTCs distribution of the software? If users are allow to keep up with the latest and greatest developments for the platform I suspect the big players will start to sweat a little. Only time will tell, but it’s starting to look good.

People who use their Huawei E160G on Three will know that in the Windows client you can send and receive SMS, this will come at some minor cost of £0.10 per SMS, and you can add bundles onto your mobile broadband account to make this cheaper.

Similar functionality can be achieved in Linux, and it’s very useful if your like me and want to drop someone a message when you don’t have your phone around.

For this we’ll be using Gammu, which is a toolset for managing phones via the AT GSM command set. It was originally forked from Gnokii, which was a similar toolset for Nokia handsets. As the E160G opens a serial port with access to the AT command set this is a relatively easy tool to setup.

First of all, we need to grab the packages. As these are standard Debian packages you should have no issues.

# sudo apt-get install gammu

Next, we need to configure Gammu to pickup the correct device. Check your dmesg for the serial port:

$ dmesg|grep tty
[12321.308078] usb 5-3: GSM modem (1-port) converter now attached to ttyUSB0
[12321.308275] usb 5-3: GSM modem (1-port) converter now attached to ttyUSB1

Edit ~/.gammurc, or run gammu-config to change the device settings. Your ~/.gammurc file should look similar to:

[gammu]
port = /dev/ttyUSB0
model =
connection = at19200
synchronizetime = yes
logfile =
logformat = nothing
use_locking =
gammuloc =

Give it a test by getting all the SMS from the device:

# gammu getallsms

This should bring back all the SMS currently stored on the stick, which should include your login details for the Three website (unless you’ve deleted them). To send a SMS use the “sendsms” command:

$ gammu sendsms text 07874454543
Enter message text and press ^D:
Test Message!!!!!1!
Sending SMS 1/1....waiting for network answer..OK, message reference=2

Gammu has a lot more tools and options to explore, now you have the basic config you can setup a SMSD, which can expose the ability to send SMS to a network. Also, Gammu has a python interface so you can possibly build your own frontend client for sending SMS. For more details explore the Gammu Wiki.
