The internet used to eat away a large portion of my day, especially social networking sites, forums, blogs or information-dense sites where the amount of “interesting” information is so much, you never actually get to the point where you find the information you were looking for in order to work productively. Same goes for sites like Linkedin where you are supposedly networking amongst business people, yet very few people actually stick to using it as a networking tool and before you know it, you’ll be browsing and browsing and browsing Linkedin profiles the whole day instead of actively networking amongst real business people to get some real business done.

The same principle applies to instant messaging; even though it’s a very useful tool to stay in touch, how much does your productivity suffer when you have all 600+ myspace contacts, 400+ facebook contacts, 150+ GTalk contacts, 50+ YIM contacts, 50+ MSN contacts and 50+ Skype contacts loaded into Pidgin at the same time and one of those people decides to start a conversation every now and again. Pretty soon, you’ll have your whole desktop full of chat windows and any form of productivity will cease to exist. I find that MSN and YIM contacts are the biggest chatters (statistically proven – anyone has a 100 Million to waste in researching to why this is the case?) as well as facebook contacts who assume you’re available for chat since you’re always displaying online (thanks to the facebook plugin for Pidgin). I used to have a custom developed MXIT plugin for Pidgin as well, but removed it within the first few days after realizing that a permanent online presence on MXIT means a gazillion “howzit” popups a day. (haven’t used my account in years, wonder if it still exist, lol) Eventually I decided to just use Skype and ONLY open Pidgin (with all the IM protocols enabled) when I really don’t have anything better to do (which hardly happens).

Those who complain that they can’t get hold of me, I have told to send an email or use the good ol’ telephone. It actually reminds me of an infamous computer science lecturer who gave up on email and placed a permanent auto-responder on his email account telling people to fax him if it’s important while asking his secretary to choose the three most important faxes each day and to throw the rest away. He only responded to the three most important faxes and then continued his research – guess why he received over a thousand faxes day …

One tool which will time your online presence is called TimeTracker, a Firefox plugin which will simply display a clock on your status bar telling you that you have spent x amount of time inside Firefox in the last 24 hours.

Even though this might motivate some people to waste less time online, it’s hardly effective if a lot of the work you’re doing, requires an open browser.

The solution is LeechBlock, limit your time per group of sites to x amount of minutes a day (or per any time period you want) and let Firefox physically block your access to these sites after you run out of time credits. I’ve allocated a whooping total of ten minutes to all social networking sites during a 24 hour day, that means once I access one of the social networking sites on the list, the timer starts running for all of them and after ten minutes, all of them are blocked.

LeechBlockLeechBlock is a simple productivity tool: an extension for the Firefox web browser designed to block those time-wasting sites that can suck the life out of your working day. (You know: the ones that rhyme with ‘Blue Cube’, ‘Pie Face’, ‘Space Hook’, ‘Hash Pot’, ‘Sticky Media’, and the like.) All you need to do is specify which sites to block and when to block them.

You can specify up to six sets of sites to block, with different times and days for each set. You can block sites within fixed time periods (e.g., between 9am and 5pm), after a time limit (e.g., 10 minutes in every hour), or with a combination of time periods and time limit (e.g., 10 minutes in every hour between 9am and 5pm). With the ‘lockdown’ feature, you can block sites immediately for a specified duration. You can also set a password or random access code for LeechBlock’s options, just to slow you down in moments of weakness!

The sites to block can be specified using wildcards (e.g., *.somesite.com) and exceptions (e.g., +allowme.somesite.com).

LeechBlock also keeps track of the total amount of time you have spent browsing the sites in each block set.

Back at varsity, a buddy used to disassemble his computer when it was exam time, very extreme, but it seemed to have worked for him. My current setup of productivity boosting tools are (and have been) working wonders for me (combined with the fact that I don’t sleep nearly as much as the average person which gives me even more time). Uninstalling useless, time-consuming social networking applications will also free a lot of your time, especially applications like humanpets, farmville and the tons of other garbage / useless applications people get sucked into.

Feel free to share what productivity boosting methods and tools work for you.

An interesting question which I’ve read somewhere on a forum was “What is the formula for the human body?” After a bit of reading, I’ve compiled an answer that might make you wonder, “why would anyone actually want to acquire such information?”. Since I stumbled upon it and read the question somewhere, here is a possible answer.

Chemical Abstracts arranges its formulae according to a system known as the Hill Order, developed by Edwin A. Hill and published in 1900. A compound’s Hill Order formula may be different from its empirical formula. There are some basic rules to follow to put your molecular formula in Hill Order:

  1. For carbon-containing compounds, carbon (C) appears first.
  2. Carbon is followed immediately by hydrogen (H), if present.
  3. Compounds are listed by increasing number of atoms.
  4. All non-carbon element symbols follow in alphabetical order, and within alphabetical order are listed by increasing atom count.

For example, the empirical formula for Sodium Chloride is NaCl. The Hill Order for Sodium Chloride is ClNa. For Sodium Biocarbonate, the empirical formula in NaHCO3, and the Hill Order is CHNaO3.

C(E28)H(E28)N(E27)O(E27)P(E25)
S(E25)Ca(E25)K(E24)Cl(E24)
Na(E24)Mg(E24)Se(E24)Fe(E23)
Co(E23) Cu(E23)F(E23)I(E23)
Zn(E22)Si(E22)Mn(E20)B(E20)
Cr(E20)V(E20)Sn(E19)Mo(E18)
Ni(E16)

In defining ourselves in this manner, we see that: We are water-based molecules (more so than being carbon-based); by weight we are 65% water in composition.

Using this format, we will smartly subdivide these human molecules into three groups:

Mx = Male Human Molecule
Fy = Female Human Molecule
Bc = Immature Human Molecule [i.e. a Baby/Child aged -9 mo. to 15 yrs]

basic human chemical reaction is (is a ‘couple’ forming reaction):
CE28HE28NE27OE27PE25SE25CaE25KE24ClE24… CuE23FE23IE23ZnE22SiE22MnE20BE20CrE20VE2…

To build on this, we also need to add in the formation of a child (human molecule). In doing this, it would be nice to simply use: [M] for the Male molecule, [F] for the Female molecule, and [B] for the Baby/Child molecule. However, these symbols are already assigned: M=Mega (or 10E6), F=Fluorine, and B=Boron.

Next in line, we might smartly choose the standard procedure for symbolically labeling elements, which is to use the initial letter as a capital, and the second letter as the lower case. This would give us [Ma], [Fe], and [Ba]; but as we know ‘Ma’ is short for Mama, Fe=iron, and Ba=Barium.

At this point, we would be wise to keep the initial letter as: M, F, and B, but to choose new (second) lowercase letters. And since the letters ‘x’ and ‘y’ seem to intuitively feel correct, owing to the fact that the 23rd human chromosome determines the sex of the individual, according to the rules: XY=Male and XX=Female; then we will lean towards the letters ‘x’, ‘y’, and ‘c’ (child) for the choice of our (second) lower case letters. However, for our final decision, we will use the letters in a sort of ‘reverse manner’ so to allow the ‘feel’ of the situation to prevail. Such that, throughout Human Thermodynamics we will adhere to the symbol choices of:

Mx = Male molecule (analogous to Extreme-Sports)
Fy = Female molecule (analogous to Gynecology)
Bc = Baby/child molecule (or a person aged 0-15yrs)

This, in conclusion, is owing to the fact that it seems to ‘feel’ sort of strange, or unnatural, to use the symbol choices of: ‘My’ (for the male molecule), and ‘Fx’ (for female molecule), as would be the case if we let the 23rd chromosome rule dictate [i.e. XY=Male and XX=Female].

I’m not even going to attempt to give a better explanation, Brian Greene, who is currently specializing in theoretical physics, particle string theory and also doing work on the unified theory does a fantastic job explaining the concepts so that everyone can understand it.

Problems With Energy Saving Light BulbsEnergy saving light bulbs are the typical type of thing governments usually do; when things go wrong, they patch it and then patch it some more until eventually it falls apart. It’s like painting rust; the same goes for energy saving light bulbs, it’s a quick fix to spending money on decent alternatives to energy.

The idea of an energy saving light bulb is good, until you look a little closer. Besides the concerns of these bulbs increasing your risk of skin cancer, causing migraines, possibly triggering epileptic seizers in people with photosensitive epilepsy, increase skin rashes if a person has a light sensitive skin, cause discomfort for people suffering from lupus (a condition which causes swelling and pain as the body attacks its own tissue) and so forth, the light bulb itself contains enough mercury to be a cause for concern.

The EPA (Environmental Protection Agency) suggests the following: if one of these bulbs break in your home, don’t vacuum the shards up; rather sweep them away wearing rubber gloves or pick up the shards using sticky tape as protection from the mercury. Also make sure no one inhales any dust, and seal the broken pieces in a plastic bag, to dispose of at a council dump and NOT in a normal household bin!

The mercury content in an average energy saving light bulb is no more than 5 milligrams – and would fit on the tip of a ballpoint pen – but it’s still a hazardous material that could poison landfills (meaning it will eventually end up in our drinking water) or directly cause health problems in the event that one of these are broken. For this reason, used energy saving light bulbs need to be recycled rather than going in the bin and since this is a temporary solution to a much bigger problem, we need to continue looking for alternative sources of energy and keep on pushing for funding to further develop alternatives that are not more harmful to the environment than the current ones are.

Stuck in Windows (have only tested it on an XP Virtual machine) and need to do development work, but constantly have to associate files (.php, .pl, .htaccess, .css, …) as Windows doesn’t support them by default?

Write a script on your webserver to get a list of all the extensions being used and write a bash script in Windows to associate them all with whichever program you need it associated with (Post a comment if you need help).

How do you associate files via command line?

Type: assoc <.extension>=<filetype>

assoc-command

Let’s say you need to add new types or want to change the program being used to open txtfiles or phpfiles or whatever filetype you want to reassign to a different program.

In Windows Explorer go to Tools -> Folder Options -> File Types

folder_options

Here you can reassociate the txtfile or any other file type with whatever program you want and add other file types.

Hope this saves a couple of Windows victims a bit of time ;-)
