How to

(nice title, isn’t it?) 😉 Although AJAX techniques are now widespread among the web-developers community, there’s still something that can’t be done using pure AJAX techiques (whatever that means): file uploads. There’s no way to grab a file using JavaScript and send it to the server using an asynchronous request. I guess the main reason […]

I finally moved to an Intel machine. Despite the dramatic speed improvement in everything Java-related, namely Eclipse, there’s another big advantage: being able to run IE on Windows using a virtual machine. Unfortunately, that’s something every web developer must do to ensure his or her application will work on the most used (and crappy) browser

Or How I learned to stop worrying and lock the EOObjectStoreCoordinator So those of you who read the WebObjects Developer mailing list know I’m a bit obsessed about concurrency issues. Namely concurrent data write operations, specially when you have lots of derived data on the database due to performance issues. A few months ago, I

This was it. I spent the weekend migrating GAEL‘s Xserve to Leopard Server. It all went well, although some more or less serious issues poped up. Our server is used mainly for hosting web content and applications (php, perl, and of course, WebObjects). It also handles some Subversion repositories and some other minor stuff. I

Alphabet Inc. is not pleased with Google Fiber’s performance, and has ordered cost-cutting measures to be enforced. Google Fiber aims to deliver high-speed Internet by laying down fiber optic cables to provide the kind of Internet speeds it wants to deliver. The project has rolled out very slowly, and only seven metropolitan areas are currently

I use Retrospect to backup most of the machines at GAEL. You may wonder why do I use a commercial tool that still shows it’s OS 9 roots, instead of open source alternatives. Well, Retrospect has some cool advantages (namely the very good support of laptops that may be disconnected abruptely from the network while

It’s becoming more and more common on the web to create pages that, on some situations, display some object over the page content. This could be a photo (using LightBox), a movie (like Apple does on their trailers site for non-HD trailers), a dialog, a color-picker, etc. In that situation, you often want to make

Well, WWDC is almost done, I’m waiting for the last session on Level 3 of Moscone, near one of these really big windows. It’s a really big pain to not being able to write here all that I have learned about WebObjects (for those of you who don’t know, WWDC sessions are covered by NDAs).

I found out the hard way the recently released third main version of Firefox has a serious issue related to the order in which the Javascript code is executed in a page. The bug is somehow related to the files being, or not, cached on the browser. Wonder Ajax framework adds a lot of Ajax

I still didn’t have time to investigate this deeply, but here goes anyway, as I didn’t find the answer to this anywhere. I had the problem described in the Apache 2.2 adaptor: SSL fails on FreeBSD amd64 thread in the WebObjects-Deploy mailing list. As the thread suggests, the problem is not related to 64 bits
