nospam@example.com (Gavin Henry) — Sun, 13 Jul 2008 20:53:05 +0100

Shh. Don't tell anybody, but you can download RT 3.8.0...RIGHT NOW

RT 3.8.0 will be officially released on Monday, but a careless release
engineer seems to have uploaded the final release of RT 3.8.0 somewhat
in advance of the announcement. Now's your chance to be the first
person on your block to deploy the new RT.

On Monday, you'll likely see email and a blog post about all the great
new
features in RT 3.8 - including:

- a redesigned visual style.
- the ability to "star" your favorite tickets, just like
Firefox 3's bookmarks
- comprehensive support for signing, verifying, encrypting
and decrypting email with the Gnu Privacy Guard
- dashboards built out of saved searches, graphs and charts,
which you can share on the web and subscribe to by email
- new saved settings to control how often RT emails you
- pretty visual charts showing the relationships between
sets of tickets
- a WYSIWYG editor for composing replies to tickets
- calendar feeds of task due dates
- per-user timezone settings

...and a whole bunch more neat stuff.

You can download RT 3.8.0 at:

Flexi Time Manager Shortlisted for National Business Award

nospam@example.com (Suretec) — Fri, 13 Jun 2008 13:59:56 +0100

Flexi Time Manager "in the pink" after shortlisting for National Business Award

Entrepreneur Louise Wreathall has been shortlisted for the ‘Best Mumpreneur’ award at the National mother@work awards 2008. Louise, creator of Flexi Time Manager, which offers an online flexi time recording service, launched her business last year and has seen it go from strength to strength. She will attend a reception at 11 Downing Street on 18th June, where the winners will be announced.

Louise says, “Being shortlisted for this award means so much to me. Of course I’d be thrilled to win, but reaching the final stage itself shows that my work in getting the business where it is today has paid off.”

As a working mother who returned to work after a career break, Louise knows how important flexi time can be. Working in the HR department of a charitable organisation, she was responsible for administering a time consuming flexi time system for 30 staff, using scraps of paper and mental arithmetic to calculate hours worked. When staff numbers doubled, she knew something had to change, and set about creating an electronic timesheet system. By 2005, Louise had set up the business and set about trialling her own online time management system. With the help of Enterprise North East Trust, and local networks Women Into Business and Aberdeen Entrepreneurs, she learned the fundamentals of business management, finally launching the fully tested web application in November 2007.

Suretec designed and implemented the Flexi Time Manager Solution.

Spring 2008 - a UKUUG Conference Review

nospam@example.com (Gavin Henry) — Thu, 03 Apr 2008 13:37:12 +0100

I got back last night, after a somewhat hectic Flybe.com flight (long story).

I really enjoyed the conference, my first time speaking at one, bit nervous, but it can only get better

Tuesday:

As I arrived around 10.30am on Tuesday, I just caught the end of Testing with Selenium, very handy bit of kit.

- System Configuration : An end to hacky scripts? This was very good and showed an alternative (IMHO, much better) to things like Cfengine and Puppet
- An Introduction to DBIx::Class - Tom Hukins is an excellent speaker and a very nice guy to boot. Had some good chat in the pub afterwards, mainly Perl related. He knows his stuff.
- Building a new model for account management - I've meet Simon a few times before, he's another great guy. His talk was about a completely new way to manage accounts (and much more) that they are using at Edinburgh uni.
- Software patents and open standards - This was one hour of very interesting, worrying and intelligent discussion.

It was good to see so much Catalyst usage too.

The rest of the day was spent chatting with Matt and Mike, meeting lots of very clever people, drinking, eating and generally have brilliant discussions over dinner and in the pubs

Wednesday:

I sat in the PostgreSQL talks all day.

Simon did an excellent job being the event host. Dave gave us an insight into how the Postgres project works..pretty much like other well organised Open Source projects of this size. Chris fewtrell talk was interesting to see how Postgres is used at the core of a business.

Explaining the Explain was very technical, but also fun. I think some useful things for Postgres will come out of the HA talk.

Mark Cave-Ayland was another excellent speaker and his talk on Integrating Map Data with PostGIS was well worth attending.

A real eye-opener was Simons talk on PostgreSQL Performance Features in 8.3. Well worth an upgrade!

Simon has written his thoughts on the event up too.

Catalyst Book Review Out

nospam@example.com (Gavin Henry) — Mon, 25 Feb 2008 09:43:17 +0000

Dave Cross has published a Catalyst Book Review that was written by Jonathan Rockway and published by Packt Publishing.

...I knew that Catalyst was something that I should take the time to learn, but it always seemed like such a daunting task.

For that reason, I was really looking forward to reading this book. I'm the kind of person who learns best from reading a book and I hoped that with a few tube rides reading this book, coupled with a few practical sessions in front of the computer, I'd soon have Catalyst. I'm sorry to report that having read the book, Catalyst is almost as confusing to me now as it was before.

I don't think that much of the blame can be laid at the feet of the author. Jonathan Rockway is a member of the core Catalyst development team. I've read his blog and his contributions to various mailing lists. He obviously knows his stuff. I think he's been badly let down by his editors.

I have not read it so I can't really comment.

Thanks,

Gavin.

Amanda 2.6 Beta Released

nospam@example.com (Suretec) — Tue, 22 Jan 2008 10:27:27 +0000

The Amanda 2.6.0 beta release offers some excellent new features. Ones that appeal to Suretec are:

A Perl Interface

Encryption methods (various techniques have been available previously) - Simple and GPG

There of course many other excellent additions and fixes.

So, why is the Perl Interface so cool? Well, a while ago we asked about using the Perl interface for use with an LDAP^[?] Configuration Backend, but at that time Amanda wasn't ready.

The Perl interface is a great addition and easy to understand why it was needed.

We'll keep you updated on how the betas progress and when we start hacking up an LDAP interface

Binaries and source can be downloaded from Zmanda.

A Catalyst Appliance?

nospam@example.com (Gavin Henry) — Tue, 22 Jan 2008 10:21:30 +0000

We have had some interesting discussions about offering a locally hosted version of a Catalyst Web Application called Flexi Time Manager.

The question was also raised on the Catalyst Mailinglist, with no replies...so we raised it on the PerlMonks forums at Offering a locally hosted solution?

A very interesting response about doing an appliance:

Gavin,

I've been pondering these questions in anticipation of some stuff i'm working on. Some corporations prefer to have the stuff in-house for a few reasons. These come up alot:
1. Security - they may feel unconfortable having their data outside the company. it may even be policy
2. Network outages - if its internal, your site or their network connection going down won't affect the in-house application (unless you use the light frontend that goes back to your servers)

Thoughts to consider:
1. How much control do you want to give them in terms of access to the source code and the ability to break things even if well meaning. Will they need to sign an NDA?
2. How is the application maintained? Do you have a tunnel into their environment to fix things? (will they consider this a security risk?)
3. How are updates applied? Onsite cdrom/flash drive? Downloads (like IPCop), automatically downloaded and installed? How do you deal with a failed update.
4. What happens when they want to connect some other system to your database to pull the timesheet data?
5. Security. What liability is involved if the appliance is the mechanism for the breach. And would the appliance provide a method for securiy breach (see #2 and #3).
6. Legality - if you have gpl code, you're ok when its a service, when leasing hardware/software youre approaching a greyer area the RMS wanted to kill with GPLv3 (it didn't make it into the final cut)
7. If your model is based on usage, how do you guarantee you're sending back the appropriate data and a firewall isn't getting in the way.

I'm personally leaning towards the leased appliance model. You "lease" a box with the software installed on it. Providing in that fee is an "update" subscription service, where the software will poll the update server and pull the encrypted & signed updates down. Perhaps with a web interface for the company admin to decide whne to apply the updates. Of course the leasing is noticably more expensive that the web version (for the updates and support).

Applications that do some of that I was talking about:
1. IPCop - downloadable signed updates
2. Tivo - ideal model in my mind (at least for the hardware end result)
3. Google search appliance (to they offer the google office apps as an appliance yet?)
4. Vigilant Minds security appliance - (was originally nessus with a rockin web interface)
5. Salesforce.com and SugarCRM i think also have appliance versions as well.

You want the corporate types to think of the box you provide like a Tivo, not like software they purchased. In the latter you end up with the companies wanting you (or themselves) to make customizations to the app. Enough of those and you become a development shop and not a service provider.

Now all that said, the Xen/Vmware image idea might work well. I've dabbled with using a single Xen image on a piece of hardware just to cope with the fact that hardware continually improves and unless you're buying in bulk from Taiwan you're guaranteed to not hav ethe same platform to install on year after year. It will also offer greater flexibility for larger companies who have migrated to a Vmware setup. The downside is that if they stop paying, they can effectively keep the Vmware image and get into it whereas an appliance can be reasonably locked down to make it less likely. (Downloads are something people put little weight WRT to stealing.)

How does this relate to perl? There are dozens of modules out on cpan that can help with accomplishing the task of remote updates, package signing, etc...

Food for thought.....

Flexi Time Manager - A Cost Effective and Time Efficient Solution for SMEs to administer flexible working

nospam@example.com (Suretec) — Wed, 31 Oct 2007 14:12:38 +0000

Flexi Time Manager is a web application that provides a cost effective and self-contained administration system for recording and calculating flexitime. Designed to help small and medium sized businesses introduce or extend flexible working for staff, the system can be accessed at a mere 54 pence per employee per week (£30 per employee, per year) and does not require specialist software or hardware, just an internet connection. For firms that already operate flexible working, Flexi Time Manager will ease the administrative burden associated with calculating employee flexi time. Employee hours are input by the user at any time and their data is then automatically calculated, totalling the working time, flexi credit or debit and flexi carry forward.

Louise Wreathall, creator of Flexi Time Manager explains,

“Due to the changes in legislation, employers have to seriously consider how to put the necessary procedures and protocols in place for effectively managing flexible working. Smaller firms often don’t have the money, resources, or expertise to put flexible working into practice. Flexi Time Manager offers these organisations the means to efficiently administer flexi time at considerably lower cost than by manual calculation. The database includes all of the features of a sophisticated flexi system and can be used on any PC. This makes it ideal for those who work remotely. As it is web-based there is no expensive hardware or software needed, only an internet connection and web browser.”

Flexible working has been the hot topic of many government announcements this year. Both Tory leader David Cameron and the Labour Minister for Children, Young People and Families, Beverley Hughes, have called for an extension to the right to request flexible working. Changes in legislation and the Government drive to promote better work life balance has led to almost 95% of requests for flexible working being granted by employers*.

Flexi Time Manager is suitable for users from a wide range of industry sectors from University departments, medical surgeries and voluntary organisations, to accountancy firms and solicitors. The versatility of the system allows it to be tailored to individual user needs, as Louise explains,

“Each person can set up their own unique profile on the database, inputting basic weekly hours, limits to the working day, minimum lunch times, core working times and minimum daily hours. All subscribers are provided with a unique username and password, so that each time they use Flexi Time Manager their settings will remain. Individuals can log into the system at any time to view their total hours and flexi balance ‘as they go’. Flexi Time Manager can also record holidays, sick leave or any other form of absence.

“The system is beneficial for organisations that employ a high percentage of part time (often female) staff. With the new laws granting carers with children under six or disabled children under 18 the right to request flexible working, it is necessary for all employers to plan and prepare for the introduction of dynamic patterns of work for some or all staff.”
