Open Kosmaczewski

I’ve just uploaded a new project on Github called delicious_wp: it’s a small Ruby script that simply fetches the items stored in del.icio.us the previous week and creates a blog post with them. You can set up a small cron job to execute this script every week, which is what I’ve done for this blog [...]

There are basically two things you can do to earn a living when you write code:

Consulting
Products

When doing consulting, you write code, and somebody else owns it; you are blamed for its bugs, rarely praised for its benefits, and usually you only sell one copy of your work. When working on products, you write code, and [...]

When you are a kid in Argentina, there are invariably three questions that you’ll always get asked whenever you meet a grown up person:

How old are you?
What’s your favorite football team?
What do you want to be when you grow up?

The answer to the first question depends on the moment, of course, and it’s simply a [...]

This is something I should have done much earlier, but hey, better late than never: akosma software has a new website and I’m happy to invite you to take a look at it.
Open Kosmaczewski will slowly become a more personal platform, as most of my future iPhone-related material will appear in the new akosma blog. [...]

Historically, we can distinguish really big software companies for providing, at least, four major kinds of products: an operating system (sometimes open sourced at a certain level), a web browser (with various degrees of standard compliance), a suite of office applications (slightly compatible with everyone else’s), and a programming language with curly brackets (generally incompatible [...]

Today it’s the 5th anniversary of the article that would eventually become the first post of this blog. I was leaving Buenos Aires, again, and I wrote that on my old G3 iBook in the airport of Ezeiza, right before boarding. That trip was very important, for many reasons that don’t fit on a single [...]

I found today that Mobile Safari, the browser bundled with the iPhone, has a very strange and annoying behaviour when it comes to web apps. In fact, when you “install” web applications with the <meta name="apple-mobile-web-app-capable" content="yes" /> tag in the “Home Screen”, the USER_AGENT header sent to the server is different to the [...]

Yes, it’s possible. Even if Objective-C is one of my preferred programming languages, in any case I think it’s worth mentioning that, 2 years after the official iPhone SDK has been announced, the iPhone development landscape has really grown up, and many, many different options are available today. This article provides a very high-level enumeration [...]

Nailing down the idea, the navigation and the UI of your next killer iPhone application is as important (if not more) as writing good code. This is why this post will showcase some recent iPhone designer products, all providing a paper-based, iPhone-shaped and iPhone-sized support for sketching out iPhone apps with your client (or just [...]

This paper will highlight the results of an extensive research conducted since the mid 90’s, on the effects of the consumption of beverages based in the plant known as Ilex paraguariensis, in the framework of software development process activities in South America and some small parts of Europe.
This paper will provide an introduction to the [...]
