First install afraid-dyndns with the command:
sudo yum install afraid-dyndns
Now open the configuration file /etc/afraid-dyndns.cfg and we need to change the following:
Notify = root@localhost # leave empty to suppress notifications
CacheFile = /var/cache/afraid-dyndns/IP
AccountHash = <value>
For the Account hash, head over to http://freedns.afraid.org/api/ login and then click one of the XML or the ASCII links there. Once the page has loaded, look at the URL which is of form:
The number above that you see in the actual URL is the account hash that you need to configure in the config file. Though it is very simple but could never get this correctly 🙂 until today.
All of us use the keyboard to create symbols daily. Look at the thumbnail. That’s a simple symbol created with just four keys.
Symbols existed even before the alphabets. Over the years they have been part of folklore, myths and legends. Some have stayed on as indelible marks. Some, like the swastika, are better forgotten. Symbols have remained potent. If you doubt their visual power, then look no further than logos. People shell out millions for a three-pointed star on a sleek hood or a prancing horse. Puzzled? The first one is the Mercedes logo and the latter is Ferrari’s.
In this post we will take a look at some symbols or images that we can reproduce using just the keyboard. The superset of creating images using letters/symbols on the keyboard goes by the name of ASCII (American Standard Code for Information Interchange) art. You need two things to draw ASCII art anywhere online…a keyboard and lots of patience.
How Do We Create Cool Symbols Using The Keys On Our Keyboard?
Text art/ ASCII art can be drawn using any text editor, online or offline. The simplest is Notepad on Windows or TextEdit for Mac. More advanced word processors have features which are more adept at selection and alignment functions like Overtype and Insert.
Can text art be learned and are there any special techniques to create cool figures?
The answer to the first is yes, it’s fairly easy to learn. There are some basics of course that need to be kept in mind. The rest as they say is practice.
Some basic techniques for keyboard symbols are :
- Use a fixed width (Courier, Monaco, and Fixedsys) font, to draw your symbols because every type of computer has them. Also called as a monospaced font, they are fonts whose letters each occupy the same amount of space and thus they are also easier to align with one another.
- Experts speak about noticing the difference between serif (with a short line at the end of the character) and sans serif (without the line at the end) fonts for text art. The display may differ from one computer to the next depending on the default type of font. One advice usually is to use the vertical bar (|) instead of the capital I (I) to draw vertical lines with the sans serif font.
- Draw in the Overtype mode on your word processor. This makes it easier to put in another character without re-aligning the neighboring ones.
- Use the Space key instead of the Tab key.
- Draw a rough sketch of the figure on paper and then put in place keyboard symbols and letters that bests approximate the angles and curves of your figure. For instance, o or @ for eyes, “ for hair etc. The most common symbols used in ASCII art are: / | – _ ( )
- Start small with simple symbols or figures. Example – a rose or a face.
- Begin from a simple area of the figure which has a shape that’s easy to type in.
- Go for close approximation rather than pinpoint accuracy…after all, accuracy is more suited for line art.
- Correct your mistakes early because leaving them for later will mar the precision and placement of symbols.
- Free your imagination!
