Encryption

cyberpunk desk.1920x1280

That’s the entry screen to my encryption program i developed some time ago. Every time you start it, it displays a new screen with thousands of random numbers. In order to get in you need to enter a code based on what you see on the screen, but you have to know exactly what to look for. This is a good example of a keylogger safe procedure. It doesn’t matter if some spy program registers your keystrokes. The same keystrokes will probably never be used again.

If you could study the source code of the program, maybe you could unveil the secret of the whole procedure. But to make the challenge a bit more interesting, the source code of the program has been encrypted by the program itself.

Counting the days after Christmas

Does the Twelfth Night fall on January 5 or 6? And why is it called the Thirteenth Night (Trettondagsafton) in Sweden? The traditional answer is that it falls on the 5th and here is why?

Here you can see why the Twelfth Day is not among the so called Twelve Days of Christmas.

Having spent some time during the holidays discussing this on Facebook I felt the need to clarify this.

The discrepancy between the English and Swedish way of naming the days after Christmas can easily lead to so called fence post errors, a common issue in computer programming.

Reducing image display size by changing width and height parameters in the HTML code

As most people know that is almost always a really stupid way of reducing the display size of an image. The recommended way is of course downscaling the image using an image editor program, thus creating a completely new file containing less data.

But can there ever be a point in reducing image display size using the HTML width- and height-parameters?

The answer is yes.

The main use for downscaling images by html-parameters would be on a web page where users are expected to zoom in. The nice thing with images downscaled like this, is that they wont become blurry when the users zoom in (like normal images will). In most web browsers you can zoom in pressing the keys Ctrl+Plus.

WordPress doesn’t allow me to display images downscaled like that but you check out such an image I published in another blog.

You see the point?

The wise and foolish virgins giggle with their bodies glowing bright

The Carpet Crawlers is one of my favorite Genesis songs from their album The Lamb Lies Down on Broadway recorded in 1974. Right now I’m completely spellbound by this excellent arrangement and performance by Ray Wilson.

Touched by the songs enigmatic words I created a new video of the song today where I added the lyrics. I published it on Youtube today.

Assamwise Gamgee and Snowdo Baggins

Maybe the two most important people during 2013

Mr Snowdo Baggins is of course the ringbearer. The ring is a keyring. The key is an encryption key to an encrypted hard drive with information oh so coveted by the burning Eye of Barad Dûr.

So why is Assamwise Gamgee – mr Snowdos loyal helper – important?

Let me quote the science fiction author Bruce Sterling:

It’s incredible to me that, among the eight zillion civil society groups on the planet that hate and fear spooks and police spies, not one of them could offer Snowden one shred of practical help, except for Wikileaks. This valiant service came from Julian Assange, a dude who can’t even pack his own suitcase without having a fit.
