Text-Image generation - VirtualPathProvider for EPiServer (and ASP.NET in general) – Part 1

The module code is already available on Epicode SVN, the relevant wiki pages will be following as soon as documentation is complete.

The use case is as follows:

• The client wants the site to look exactly as in a template provided as a image,
• the text is using a non standard font that is not available on 60% of Windows machines,
• the site does not use flash.
• the site needs to be equally good looking in IE6 (more about it later)

The solution was to generate images, but how to do it the right way? This has presented us with a once-in-a-lifetime :) opportunity to create a virtual path provider, do something good and learn something new & cool in the process.

CogniScale - virtual hosting made easy

We’ve not been talking much about it and that’s partially my fault as well (busy with other projects), but Cognifide has a really cool initiative called Cognifide Labs that we intend to grow over time. The plan is to devote up to 10% company time into side projects that help us grow expertise and allow our devs to dwell into interesting technologies, methodologies and languages and develop their skills.

One of the first projects (that I took part in) is CogniScale - an app that allows FlexiScale users to manage their servers. Here’s the story…

Is it Yeti? Is it a magazine? I sense disturbance in The Force

There’s been a great link to an article forwarded to me today to a Newsweek’s Apple PR division Technology columnist Steven Levy. Where he claimed that he has lost (although he is not sure (LOL) ) his MacBook Air. blogosphere is throwing their hands up in the Air ;), but really… it’s so funny on so many levels that people are all about the story (ironically so am I with this post). The article is such a great example of the Apple hype machine at its best. Let me elaborate

Episerver's brand new blogger

I’m really glad to notice that Marek is getting into blogging about EPiServer. Marek is a really bright developer and a colleague at Cognifide with a number of successful EPiServer projects in his portfolio, we’ve worked together on Faceted Navigation (he’s the brain behind all the nifty editors in it) that I’m working on open sourcing of currently, and on the Setanta Sports Portal and the Setanta corporate site projects. Now he’s out in the wild writing about it. Go ahead and read his analysis on the performance of Episerver 4.x versus CMS 5. It appears that the CMS is getting… nah… I won’t spoil it for you… Read all about it on Marek’s brand new blog!

Faceted Service Structure

This article is a part of the series describing the faceted navigation system for EPiServer that we have developed in Cognifide and that’s already proven to be a robust solution for delivering tagged content a heavy traffic site. The engine will be released shortly as an open source project.

So how is the faceted engine structured?

Content provider

As you can see the driving force behind the engine is the Facet Tagged Content Provider. If you know EPiServer, the basic functionality of the module is roughly an an equivalent of find page with criteria for categories, which allows for searching pages tagged with facets with exclusion of some other facets and tagged some optional data, the module however is paging and and allows you to plug a feedback event handler so that your controls can accept or deny a story before they are sent to is and take part in the paging. The stories are provided to you in reverse order of publishing so you always get the latest stories first, (pretty much what any blog and any news site wants).

Faceted Navigation Engine Nomenclature

This article is the second of a series describing the faceted navigation system for EPiServer that we have internally developed in Cognifide, that’s already proven to be a robust solution for delivering tagged content a heavy traffic site, which will be released shortly as an open source project.

First of all we have to explain the nomenclature as it is going to be used quite a bit. A few terms we use pretty extensively are:

The challenges of a high traffic site with EPiServer

…with an unconventional approach to data fetching.

This article is a first of a series describing the faceted navigation system for EPiServer that we have internally developed in Cognifide and that’s already proven to be a robust solution for delivering tagged content a heavy traffic site, which will be released shortly as an open source project. The article outlines some pitfalls of EPiServer that we’ve run into and the nature of the project in which the module was used first and which influenced a lot of our design decisions.

We are The EPiServer, you will be assimilated. Resistance is futile!

This is a slightly dated post (written around November last year), that I forgot to post some time ago, so bare in mind, we’ve already started working on the faceted navigation getting open source status and I’ve updated the first sentece to include Adam Matusiak joining our team - Welcome Adam!

Over the last month or two  our hive mind has assimilated two new voices, our thoughts have become one with Greg’s, and Adam’s.

Silicon Valley says: Do what Cognifide does!

There is a really heartwarming article (if you’re from Poland) on Silicon Valley Watcher about the skills of Polish engineers, the low turnover and the general satisfaction from Polish employees by international companies something that UK as a country discovered and Cognifide in particular have noticed quite a while ago. And I really can fully relate to that, I would bet any money to stand the competency of any person in my crew against any of the top professionals out there. It definitely is a good time to be in the IT business in here. A small excerpt - worth noting:

EPiServer property getter cleaner-upper

Just a daily time saver, for reuse at another time. Any old time windows developer, will remember the fun of using the ini files with GetPrivateProfileString. As much as ini files sucked there is one nice aspect of that call - you can setup a default value it is to return in case a value is not specified in the file. Similarly in a daily episerver programming you usually want to read a value but if one is not epcified you will usually want to use another value and just move along with the progress, and not really care to have an if there to do the filling in. Not to limit the property to any specific type - the task can be nicely solved with generics to handle pretty much any type of property.
