Dans un précédent article, j’ai présenté ASP.NET Web API, la nouveauté phare de ASP.NET MVC 4, qui a pour objectif principal de permettre aux développeurs d’exposer leurs applications, données et services sur le web directement à travers HTTP. Le support d’ASP.NET Web API permet de créer facilement des API Web puissantes, qui peuvent être consultées à partir d’un large éventail de client (réseaux sociaux, navigateurs, terminaux mobiles, etc.).

Pour améliorer les performances de leur application, les développeurs ont couramment recours à l’optimisation côté client et côté serveur. L’optimisation d’une application Web regroupe l’ensemble des techniques qui peuvent aider à accélérer le temps de téléchargement d’une page Web. Parmi ces techniques, on retrouve la minification et la compression du CSS et JavaScript, la mise en cache, l’utilisation des CDN, etc.

Ce billet est le second d’une série sur les techniques d’optimisation du temps de chargement d’une application ASP.NET MVC. Le premier article sur la compression et la minification du CSS et JavaScript peut être consulté sur cette page.

Infinite redirect loop when using CakePHP

You will sometimes run into this issue when using CakePHP, I did  a few times, and randomly or so it seemed and the reason is in my case, and I want to bet in most cases, is that you are using the Auth Component, and added a new action to your controller, and simply forgot to add it to the allowed functions in the Auth Component. Make sure you add the action name that you want to be made available to anyone to the Auth.allow() call in your beforeFilter() function body in the controller where the action is defined.

Here is what has been happening in the world of African Tech this week:

  • An interview with Jason Njoku, founder ofIrokoTV, known as the “netflix of Africa”. Some good insight in a young business that makes sense because the demand is there on it. On the challenges of growth in Africa, this particular nugget stood out to me:  “At present, more people watch iROKOtv in London than they do in the whole of Nigeria.”..

dotAfricaA lot happening and since my schedule cleared up a bit, let’s do a quick round of what’s been happening in the world of AfricaTech

  • First, this is a must read by Prof. Chukwuma Charles Soludo, titled “Will Europe Underdevelop Africa Again?“, on the inequities of the new Economic Partnership Agreements or EPAs being negotiated right now between between the EU and African Countries. The first two or three paragraphs are a summary of policy talk, it might discourage you but keep on because when Soludo comes around to his own thorough and “meticulate”(meticulous and articulate) analysis of why EPAs are a bad deal for African countries, you will most certainly find a lot of gems. It is my Pick of the Week.

A REPORT ON THE TRIP TO UGUNJA This took place between 30th March 2012 and 2nd April 2012. At first I can say this way the longest road trip I have ever had (9 hours) to Ugunja. We left Nairobi at 8.00 pm and arrived at 5.30 am in the morning. On arrival we had to wait for another 30 minutes for the arranged transport to arrive, then another 30 minutes to arrive at our arranged accommodation at Ukwala. I was too tired and had to take a one hour nap so that I can start my day....

In an interesting reflection,Dinfin Mulupi over at HowWeMadeItInAfrica brings up a worry from investors in Kenya that the emphasis on social impact technology is distracting entrepreneurs from building real tech businesses. That’s a  good question to ask I believe, and legitimate from an investor point of view. As argued by Nikolai Barnwell of 88mph, an investment fund:

I was going through Dzone and bumped into this article by Bozhidar Bozhanovexplaining his frustration with the interview process at Facebook after being rejected after 3 phone interviews.

In the article Bozhanov explains that the interview process consisted of algorithmic skills and general computer science test (recursion, binary search, basic data structures), basically “easy” stuff that any computer science grad should be able to solve and that is the rub that I personally have with those types of interviews. As Bhozanov puts it (better than I could have):
