“Go Faster” Websites – Introducing Minify

We’ve been minifying and bundling CSS and JS for years to ensure quick page loads of the applications we build. We’ve now generalised, documented and packaged the tool we use for this and released it under a BSD license so others can benefit.

Most web developers know that including lots of JS and CSS files in their sites slow page load times down. Most also know that these files should be minified and bundled into one file on production sites. Most developers don’t do this though. It’s a lot of extra steps in putting your new changes live.

Also, using CDNs or setting expiry times into the future for mostly static files such as CSS and JS also significantly improves page load as clients will grab these files once and use their local cache until their expire. This also poses issues for web developers that is easily overcome by versioning these files – literally adding a version number to the bundles – for example min.bundle-v6.css would be version 6 of the CSS minified and bundled file.

We’ve been doing both of these for a long time with the sites we build. We’ve now generalised, documented and packaged the tool we use for this and released it under a BSD license so others can benefit. See our page on GitHub to download this tool and for examples of its use:

https://github.com/opensolutions/Minify

This tool will:

  • automatically find all CSS/JS files in a given directory named xxx-blah.css where xxx is a three digit ordering / sequence number;
  • minify these files and create a single file bundle including them in the correct order;
  • automatically generate template include files allowing production / development mode (i.e. use individual CSS/JS or bundles based on an application option);
  • versioning for those using CDNs, future expiry dates, etc to ensure clients load fresh JS/CSS bundles.

If you use it, please drop us a note to let us know how you get on! 

ViMbAdmin :: New Release 2.0.6

Today, we’re pleased to announce the immediate availability of 2.0.6 which has a number of incremental fixes and improvements.

Just over a week ago, we released V2 of ViMbAdmin which was a complete UI refresh.

Thanks for all the feedback and bug reports since then.

Today, we’re pleased to announce the immediate availability of 2.0.6 which has a number of incremental fixes and improvements including:

  • Domain is now ‘sticky’ when moving between mailboxes, aliases and logs making it much easier to browse a single domain;
  • A cookie is now used to remember the page length for individual users;
  • We now use grouped icons with tooltips rather than labelled buttons throughout;
  • The horrible your IP address has changed message is gone.

As usual, a full change log is available here and the packaged release can be downloaded directly here.

ViMbAdmin :: Major New Release :: V2

We’ve put some time aside over the last week to do a major UI overhaul on ViMbAdmin – specifically incorporating Twitter’s superb Bootstrap framework. The before an after’s tell a lot about this.

Over a Open Solutions, we’ve put some time aside over the last week to do a major UI overhaul on ViMbAdmin – specifically incorporating Twitter’s superb Bootstrap framework. The before an after’s tell a lot about this. Here’s how it was:

And here’s the new improved look:

ViMbAdmin - New

We’ve also closed a lot of bugs, improved the functionality and navigation and added a couple of small features.

Let us know what you think!

 

We’ve Just Launched TallyStick

TallyStick allows you to focus on what you love to do while it takes care of tracking and accumulating the time you spend on projects. As of today, TallyStick is live and open for business. Please sign up, take advantage of the one month’s free trial (with no credit card details required) and tell us what you think.

[TallyStick Logo]

Overt at Open Solutions, we manage networks, build Internet infrastructure, consult and develop web applications for many customers. Tracking the time our engineers spent on different projects – especially those on the front line hopping from customer to customer – was becoming an issue.

And we had enough. So we built TallyStick. Necessity, as the saying goes, is the mother of invention.

We believe in web applications that are simple, beautiful and functional. And after an exhaustive search, we couldn’t find one to fit our needs… so we built it. And who better to build a time tracking application for IT and other consulting professionals than those same professionals!

TallyStick allows you to focus on what you love to do while it takes care of tracking and accumulating the time you spend on projects. We believe it’s simple, efficient and quick. And we hope you agree.

As of today, TallyStick is live and open for business. Please sign up, take advantage of the one month’s free trial (with no credit card details required) and tell us what you think.

Also, all users signing up during the beta period will receive a lifetime discount of 10% on that account!

We’ve Released Some of our Nagios Plugins

We create a lot of Nagios installations for our own systems over, for customer systems which we manage and as a service over at Open Solutions. We’ve written a lot of custom Nagios plugins over the years as part of this process.

We are now making a concerted effort to find them, clean them, maintain them centrally and release them for the good of others.

To that end, we have created a repository on GitHub for the task with a detailed readme file:

They main goal of Nagios plugins that we write and release are:

  • BSD (or BSD like) license so you can hack away to wield into something that may be more suitable for your own environment;
  • scalable in that if we are polling power supply units (PSUs) in a Cisco switch then it should not matter if there is one or a hundred – the script should handle them all;
  • WARNINGs are designed for email notifications during working hours; CRITICAL means an out of hours text / SMS message;
  • each script should be an independant unit with no dependancies on each other or unusual Perl module requirements;
  • the scripts should all be run with the --verbose on new kit. This will provide an inventory of what it finds as well as show anything that is being skipped. OIDs searched for by the script but reported as not supported on the target device should really be skipped via various --skip-xxx options.
  • useful help available via --help or -?

ViMbAdmin – Migrating to github

I have recently been converted from and SVN user to a Git user. You can read about my road to Damascus moment over in my personal blog.

As such I have converted my co-workers and we have migrated ViMbAdmin to GitHub. We feel that the project is in an early enough stage to not cause too much annoyance with the current user base. We do sincerely apologise for all and any inconvenience caused.

Do you want to continue with your SVN installation?

Feel free to svn switch your base from Google Code to the following which tracks our master (i.e. stable / production / release) branch:

http://svn.github.com/opensolutions/ViMbAdmin.git

Migrating to Git

Just follow the instructions at:

https://github.com/opensolutions/ViMbAdmin/wiki/Install-using-git

and skip the database setup. Just copy over your application/configs/application.ini file to the new Git clone.

Using Official Packaged Releases?

No problem – you’ll now find new versions at:

https://github.com/opensolutions/ViMbAdmin/archives/master

 

Data Centre Technical Services

We’ve added a new service to our website: Data Centre Services. In reality, this is a service we have been providing since our inception in 2007 and our employees have been doing for other companies long before that.

ViMbAdmin – We Have a Logo!

As an example of open source in action, we had a note on our Google Code page for ViMbAdmin with a wanted section asking for a logo. Yesterday morning I received a mail from Robert Bell, self professed Head Nerd of Limeworks Australia offering some of his designers time to create one.

24 hours later, we proudly present the new face of ViMbAdmin:

ViMbAdmin Logo

With a cool new logo, we decided we needed to overhaul the login page. You can see the new face of ViMbAdmin at our updated live public demonstration page: http://www.opensolutions.ie/vimbadmin/. This has also been incorporated in a new release version, 0.2.4, which can be downloaded from here.

A sincere thanks to Robert Bell and his team Limeworks Australia for the logo.

 

We’re IPv6 Ready! Are you?

IPv6 ReadyOpen Solutions has been certified by INEX to their Platinum standard. This means both our website and our DNS name servers are IPv6 enabled.

We should of course disclose that not only do we contract services to INEX, we also developed the website and web application that powers IPv6Ready.ie!

It is vital that content owners and businesses that generate even a small proportion of their revenue through an online presence become IPv6 Ready.

To this end, IPv6 Ready is an initiative by INEX to promote the uptake of IPv6 in the Internet and broader business communities. While IPv6 has been available and in active use for over 10 years, its take up has been stunted by the continued, but increasingly limited, availability of IPv4 address space. INEX, with the IPv6 Ready initiative is encouraging businesses to delay no longer and invest in IPv6 to ensure the future of their Internet related activity.

Even if you’re not IPv6 Ready just yet, you can still make your users and customers aware that you realise the importance of this by displaying the IPv6 Pending badge which you receive by signing up at IPv6Ready.ie.

Test your site now: www.ipv6ready.ie.

Open Solutions has been a part of INEX’s operations team since April 2008, working with the expanding number of INEX Members and ensuring the smooth running of the exchange. We assist with the administration of the switching frabic, provide member support, and develop INEX’s provisioning and management systems.

IPv6 Ready is a PHP application using our standard application framework of Zend, Doctrine ORM and Smarty running on a FAMP stack.

Using Doctrine ORM with Zend Application

In this first of a serious of articles where we delve into some of the hidden treasures in our ViMbAdmin application, we look at how to integrate Doctrine ORM with Zend – and specifically Zend_Application and Zend_Controller.

In this article we delve into our ViMbAdmin application and we look at how to integrate Doctrine ORM with Zend – and specifically Zend_Application and Zend_Controller.

The first assumption (and requirement) we are going to make is that you are using Zend_Application. If you want to see a working application set up and configured for this, please checkout or browse our ViMbAdmin source code – which we’ll reference throughout this document.

Zend Application has a resource framework which allows us to bootstrap various resources on demand. We have created a Doctrine resource for this very purpose which you can download from here (and you may need to edit the class name and change the plugin path in the config code below to match your setup). Our implementation does many things:

  • instantiates the Doctrine object;
  • sets up an autoloader for Doctrine models;
  • instantiates the Doctrine manager;
  • opens the connection to the database;
  • sets all collations and character sets to UTF8 (this is hard coded but can easily be changed);
  • sets various hard coded Doctrine attributes which can also be changed.

We the add various configuration parameters to the application.ini file:

 

Or the following where $application is the instance of Zend_Application:

$application->getBootstrap()->bootstrap( 'doctrine' );

From that, you can use Doctrine to your hearts content!

We also have a Doctrine CLI script which works from the same resource. See:
