Use OpenOffice.org to Create an Image Gallery

I went on this hike on Christmas Eve – a steep trail down a ravine, with the most unusual people and the most unusual features. At the end, a gorgeous beach with surfers and pretty ladies with parasols waiting for them. Huge mansions staring down from lofty cliffs, and an amazing sunset that colored the cliffs a golden hue of honey.

I looked at the pictures, and they were pretty. Unfortunately, due to the unusual nature of the features and the number of different things you were looking at, it wasn’t quite clear how (or even if) they belonged together, and what the story behind them was. The pictures needed an explanation. A story had to be told.

The Live CD Web Server Project (Ongoing Series - Part I)

Imagine burning a CD with your latest and greatest in web sites, putting it into the computer’s CD drive, turning on, and magically you have your web server running? No installation, no configuration, no login – no viruses, no persistent hacking, no version conflicts?

The idea came to me when running a large computer cluster in a three-tier application. The front end web servers were always the worst problem: they handled all the load, they handled the majority of attacks, they were the entry point for vulnerabilities and denial-of-service abuses.

Creating an Encrypted Subversion Repository on Linux

Why?

I have my source code on a server in the cloud. That makes perfect sense – I want to have my code accessible from everywhere, even if the only person accessing the repository is my own self. Access is secured using SSH with PKI – only whoever has the private key can access the system, no passwords allowed.

While I feel pretty secure about access, it bugs me that the source code is not encrypted at rest. Whoever gains access to a copy of the repository (for instance, from a backup) has the code in cleartext. That’s absolutely not good. On the other hand, setting up an encrypted repository is too much of a hassle, and I couldn’t find anything online about how to do it.

The YouTube Conspiracy in Abby/CClive

There is a command line utility available on all Ubuntu derivatives called cclive. If you install it (sudo apt-get install cclive), you can give it a YouTube URL and it will download the video on it. I love using it for backup purposes – I upload a video from the camera, perform all my changes on YouTube, and then cclive the outcome for posterity. Just in case YouTube “forgets” about my latest cam ride.

BPM Detection in Linux

Doing a lot of cardio workouts, it is really good to have music that beats to your rhythm. The pulsating sound gives you energy and pace, both excellent ways to make a good workout, great, and to make time pass faster. When I get new music on my player (a Sansa Clip+ – the almost perfect player for a Sporty Spice) life is good. An hour of running is gone before I even know it, and when I look at the calorie count, I feel like Michael Phelps freshly crowned with Olympic gold.

The Rise and Fall of Internet Browsers

It amazes me how, since the very inception, Internet Browsers have been subject to periodic meteoric rise and subsequent fall. They do so a lot more than other pieces of software, like operating systems or word processors. It seems people are much more willing to throw out their browsers than virtually any other kind of software.

It all started with the venerable grandfather of them all, Mozilla Navigator. Marc Andreesen, the ur-type of the “smart kid with an idea brighter than even he thinks it is who goes on to think he’s the smartest person on the planet because he’s been lucky with his idea”, and his team created the software and threw it out. Instant success, huge company, enormous IPO. But a piece of software that was horrible, and got more and more horrible as time wore on.

Solar-friendly Gadgets

Living in San Diego, you spend a lot of time at the beach. There, it’s a tragedy to have no outlets to recharge things, while you have a lot of sun available. Ideally, you would use a solar charger to recharge all your devices while they are being used.

There are lots of chargers on the market. Solio makes very popular ones, but they are by far not the only vendor. Basically, all of them in one way or the other allow you to connect a variety of devices to a solar panel that outputs the correct power (voltage).

A Tale of Broken Packages

Now, you are probably going to think this is about mishaps with a shipping company. Boohoo! My UPS package arrived damaged… Sad Face… None of that: UPS is reliable as ever, as are the other shipping companies (FedEx, DHL, USPS, what have you). No, the packages I am talking about are Linux/Ubuntu packages.

One of the major advantages of using a distro like Ubuntu is that someone else figures out what works with what and makes packages available for you to download and install semi-automatically. It’s really easy and a lot more fun than the super-crappy way you install software on Windows. Instead of downloading an installer that tells you to shut down all applications before starting and then goes through a hundred screens of questions that you really don’t care about (Where do you want the software installed? Do you want the software to report usage statistics?), in Ubuntu you just say, “I want Amarok,” and there it is.

Rethinking Traditions

A confession: I don’t like signing emails. I find it stupid. You know the message is from me, after all your email client tells you that before you open it. What’s the point of salutation and signing? What does, Sincerely, Cinserely tell you that you didn’t already know?

Turns out there was a good reason for the signing. That’s from the days of snail mail and before there was such a thing as a typewriter: the presence of a signature was the only certain way to know who wrote you a letter. I remember the days when you’d get one, and you’d turn it over to read who sent it. If I had known I would feel old just for admitting I had ever read a hand-written letter, I would have believed everything science fiction told me.

Is USB the New Outlet?

I just got a refurbished Garmin Edge 705 (review to follow) along with a bunch of craptastic free sample gadget from China. The thing they had in common? Instead of having dedicated chargers, they all came with an AC/DC converter to USB.

It used to be that you were flooded with dozens of different chargers. After a while, you’d forget which charger belonged to which gadget and you had to label them. Every time you’d move, then, you’d have this monstrous mess of chargers that you couldn’t get rid of, because you had long forgotten what gadgets they belonged to.
