Error Handling 

Error Handling –  Even if you write the neatest, tidiest code in the history of computing and test it to within an inch of its sorry life, there may well come a time when a programme user comes across a bug or an error that you didn’t foresee.

Remember that because you already have the advantage of having written such fabulously neat code, it should be relatively easy to follow the paths to find the glitch. Plus, an error will be in one of three categories: it’s either a syntax error, a run-time error, or it’s a logic error.

Let’s walk through these one at a time.

A syntax error is simply a mistake in the way the code has been written. Imagine that in an essay you write “there is five locations” by mistake. The error in syntax is the singular “is” when it should be the plural “are” to match the plural noun. You’ve made an error in the rules of grammar, just as a syntax error in computing is an error in the rules of computer language grammar. Maybe there’s a lower case letter where it should be an upper case, or a bracket hasn’t been closed. Yup, it can be something as annoyingly small as that.

Then we have run-time errors. These occur while a programme is running, and is usually due either to programmer error, or perhaps some of the code is shared with another programme running at the same time and they decide they don’t like working together. It might even be malware if the programme has been infected by a virus or a Trojan has managed to sneak in.

Lastly there are logic errors. Remember we talked about logical data structures being based on yes/no or true/false? These really are down to you and you can’t blame the dog or alien invasion because it’s you who sets up the yes/no true/false dialogues. Unfortunately these are usually the trickiest to fix if you haven’t understood that what you wrote was an error.

So what can you do to prevent errors as much as possible? Prevention is always better than cure, right, so thorough testing is crucial during the design stage and while you’re writing the coding. Errors can creep in if you’re getting tired and bored, so develop the eyes of an eagle, give yourself breaks from the screen to refocus, and concentrate while you’re writing code.

How Big Is A Petabyte, Exabyte, Zettabyte, Or A Yottabyte?

This is an intuitive look at large data sizes By Julian Bunn in Globally Interconnected Object Databases.

• 100 Gigabytes: A floor of academic journals OR A large ID-1 digital tape
• 200 Gigabytes: 50 Exabyte tapes

Terabyte (1 000 000 000 000 Bytes)

• 1 Terabyte: An automated tape robot OR All the X-ray films in a large technological hospital OR 50000 trees made into paper and printed OR Daily rate of EOS data (1998)
• 2 Terabytes: An academic research library OR A cabinet full of Exabyte tapes
• 10 Terabytes: The printed collection of the US Library of Congress
• 50 Terabytes: The contents of a large Mass Storage System

Petabyte (1 000 000 000 000 000 Bytes)

• 1 Petabyte: 5 years of EOS data (at 46 mbps)
• 2 Petabytes: All US academic research libraries
• 20 Petabytes: Production of hard-disk drives in 1995
• 200 Petabytes: All printed material OR Production of digital magnetic tape in 1995

Exabyte (1 000 000 000 000 000 000 Bytes)

• 5 Exabytes: All words ever spoken by human beings.
• From wikipedia:
  • The world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes in 1986 to 15.8 in 1993, over 54.5 in 2000, and to 295 (optimally compressed) exabytes in 2007. This is equivalent to less than one 730-MB CD-ROM per person in 1986 (539 MB per person), roughly 4 CD-ROM per person of 1993, 12 CD-ROM per person in the year 2000, and almost 61 CD-ROM per person in 2007. Piling up the imagined 404 billion CD-ROM from 2007 would create a stack from the earth to the moon and a quarter of this distance beyond (with 1.2 mm thickness per CD).
  • The world’s technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986, 715 (optimally compressed) exabytes in 1993, 1,200 (optimally compressed) exabytes in 2000, and 1,900 in 2007.
  • According to the CSIRO, in the next decade, astronomers expect to be processing 10 petabytes of data every hour from the Square Kilometre Array (SKA) telescope.[11] The array is thus expected to generate approximately one exabyte every four days of operation. According to IBM, the new SKA telescope initiative will generate over an exabyte of data every day. IBM is designing hardware to process this information.

Zettabyte (1 000 000 000 000 000 000 000 Bytes)

• From wikipedia:
  • The world’s technological capacity to receive information through one-way broadcast networks was 0.432 zettabytes of (optimally compressed) information in 1986, 0.715 in 1993, 1.2 in 2000, and 1.9 (optimally compressed) zettabytes in 2007 (this is the informational equivalent to every person on earth receiving 174 newspapers per day).[9][10]
  • According to International Data Corporation, the total amount of global data is expected to grow to 2.7 zettabytes during 2012. This is 48% up from 2011.[11]
  • Mark Liberman calculated the storage requirements for all human speech ever spoken at 42 zettabytes if digitized as 16 kHz 16-bit audio. This was done in response to a popular expression that states "all words ever spoken by human beings" could be stored in approximately 5 exabytes of data (see exabyte for details). Liberman did "freely confess that maybe the authors [of the exabyte estimate] were thinking about text."[12]
  • Research from the University of Southern California reports that in 2007, humankind successfully sent 1.9 zettabytes of information through broadcast technology such as televisions and GPS.[13]
  • Research from the University of California, San Diego reports that in 2008, Americans consumed 3.6 zettabytes of information.
• Internet Traffic to Reach 1.3 Zettabytes by 2016

Yottabyte (1 000 000 000 000 000 000 000 000 Bytes)

• Named after Yoda.
