  • Trusting invalid SSL certificates is wrong
    So let me put it clear from the first line: trusting invalid certificates is wrong. And now I will explain why it’s wrong and why there are few excuses for it. We are talking here about certificates for SSL encryption, which serves basically two purposes: Privacy — data is transferred encrypted and can only be decrypted by the intended recipient and not a third party wiretapping the line. Authentication — making sure the receiving end that will be able to decrypt the data is who they claim to be and data is not diverted to a different receiver by a third party with access to manipulating our transfers.
  • URL shortener returns
    Let's start with a bit of history. is a URL shortener developed by Nicolas Hoizey in PHP eleven years ago (stylized by then as with the intention of creating a light and simple URL shortener. About seven years ago, I installed it to create my own private URL shortener at and some other open and public ones with some modifications on Nicolas's project. Shortly after, I started contributing to the project with improvements and bugfixes and almost instantly Nicolas gave me direct write permission.
  • No, don't blame the user
    It is unusual to see a computer engineer defending users. Even more if the engineer is a system administrator. It is known that the relationship between system administrators and users is tense. But when somebody tries to fool me, I get even more tense. Let's go over the facts. The registrar I'm updating the administrative contact of some domain names registered with a well-known Spanish registrar. The company listed as the administrative contact no longer exists and now the domain names belong to another company, so I have to update all the data, but that's another story.
  • RapidShare premium download with Opera
    I must blame Fonso again, because he asks me about something like FlashGot but for Opera in Linux, i.e., a way to be able to select a block of RapidShare URLs to download them with a premium account with a download manager. So when I didn't find anything, I started with it. I finally got a bash script that receives a list of links as parameters and adds them to Aria with a RapidShare premium account.
  • How to get a domain name
    Some times visitors arrive here googling for how to get a domain name (yes, I told you, I spy you), so I'm finally going to say you how to get it, then you can stop searching.

  • Opera web browser with usage report tool for Gentoo
    Opera has just announced through its desktop team the releasing of a new developing version for betatesting that includes a tool that makes reports about browser usage and configuration and without private information to send it anonymously to the company to improve the browser. Someone named this Opera 'Spyware', though it's a feature not present in official releases, which can be deactivated, you can read reports before sending it and the browser warns you about this the first time it's run.

  • Browsers and standards
    Opera 9 Safari 2.0 Konqueror 3.5 Firefox 2 Internet Explorer 7 Those are the results of running the Acid2 test against the most popular browsers. The results are eloquent, but just in case, I'm going to clarify it: it should be a yellow smiley face over a white background that when you pass the mouse over or near the nose, it becomes blue. Opera 9 passes the Acid 2 test, making it the second browser to do so, and the first browser for Windows or Linux/UNIX to pass.
