I’ve been recommending this talk a lot lately to people new to the art of speaking, who find themselves all of a sudden boosted to the front stage of an event and in dire need of help.

During the preparation of my “Learning OpenShift” course for LinkedIn Learning, I used OpenShift Local (formerly known as “CodeReady Containers” or CRC) to demonstrate the various features of the platform from a developer’s point of view.

In the past few months I’ve been writing about my software archeology experiments, including how to convert old HTML code from 1999 to run in today’s browsers, how to run Macromedia Flash movies with Ruffle, or even how to run Java applets now that they aren’t supported anymore.

As I’ve said in the past, producing videos in Linux isn’t very straightforward or stable; it can be a bit of bumpy ride. But I’m stubborn, and Linux is the platform I want to use, so when I was tasked with the creation of “Getting Started” video guides for our products at VSHN, I used Linux to create them.

My colleague Tobru recently pointed me to demo-magic, and I now seriously wonder how could I ever do a live demo without this.

At some point in your professional speaking life you will have to hold a dynamic microphone in your hands in front of an audience, just like a rock star. Not only should you be aware that it’s not a pepper mill, there’s a few more things to keep in mind while using them.

Writing a programming book is not very complicated, to be honest: it just consists of putting one word after another.

I was born in Argentina. This fact, all by itself, provides a rather unlimited amount of smiles in every person I meet.

Very often, when you work with UITableViewControllers driven by NSFetchedResultsControllers, that you want to get the “previous” or the “next” elements in the results controller.

This is a guest post + code, wrote together with Joe D’Andrea from LiquidJoe LLC!

One of my most popular answers in StackOverflow is the one I gave to the following question: “What is the best architecture for an iOS application that makes many network requests?

While learning how to write iOS applications, you will often encounter the phrase “learn C first”.

Right now, creating Universal Applications for the iPod touch, the iPhone and the iPad is not really a straightforward task.

It is very important that iPhone and iPad applications use visual styles in a coherent way.

So you flew and bought an iPad, you live outside of the US, and you would like to buy iBooks, Pages, Numbers and Keynote (as well as many other amazing apps) from your own country, huh?

Design is a fundamental part of iPhone app development. It is, without any doubt, the difference between a crappy and a great application.

Xcode does not impose any structure to your source code tree.

Memory management in the iPhone is a hot topic. And since I’m talking about it on tonight’s monthly meetup of the French-speaking Swiss iPhone Developers group, I might as well share some tips here from my own experience.

I am a big LaTeX fan, mostly thanks to my friend Cedric who introduced me to it ;) And I don’t regret it at all; there is simply no better way to create long, beautiful PDF documents, particularly during these times of dissertation writing!

Howard and LeBlanc give a very complete answer to this question in their classic “Writing Secure Code” book:

Well, you’re pretty much on your own for that :)

Lately I got curious to know how could I grab the entire desktop of my computer, and save it into a file, or display it into an NSImageView component.

After upgrading my good ol’ PC to Dapper, I proceeded to download and burn a copy of it for PowerPC systems, and I have managed to install it in my old faithful G3 iBook in dual boot, with Mac OS X 10.

“Dapper”, the new version of Ubuntu has been released yesterday! So I downloaded the ISO file, burn the CD down and proceeded to install it over my old Breezy Kubuntu installation.

Well, that was a long title. My mother recently changed her 4-year old Dell Inspiron 4100 for a brand new iMac G5, so I took that old laptop (20 GB hard disk, 256 MB RAM) and, after backing up her data, wiped it completely and reinstalled it with the following configuration:

Great day; my first full Ruby on Rails application is up and running in production environment.
