4 Ways to Collaborate Online on Group Documents

Posted on 21:40 by Unknown
One of the great things about writing group documents today, as opposed to writing group documents 5 years ago is the advent of online "colloborative editing environments". Instead of sending files back and forth through email, here are few services you can take advantage of to make collaboration with your team on written documents much easier.
1. Google Docs
If you haven't heard of Google Docs yet, then you've probably been living under a rock for the last few years. But if you have heard of google docs and still resort to using email to send files back and forth, then you should really think about using a better system. Simply create a document on Google docs and share it with all your friends. 

Some great features that Google Docs offers are:
  1. True colloborative editing - Multiple people can edit the file at the same time
  2. Version control - You can view multiple versions of the document
  3. Works for Word, PowerPoint and Excel documents, but doesn't really support things like captions, references and so on.
  4. No registration required if you make the document public.
Some disadvantages:
  1. No support for editing documents offline
  2. Support for .docx/.xlsx/.pptx files is sketchy and features such as table of contents, captions and bibliographies are not available
  3. Doesn't have as many features as Microsoft Office, or even iWork and some other competitors like SlideRocket

2. Microsoft Office Live Sky Drive

This alternative is great if you are planning on using Microsoft Word to write up your report or document. While Sky Drive acts as a great way to store you're documents to avoid emailing it every time there is an update, it doesn't work so well for collaborating in real time.
Advantages:

  1. Can upload .docx type newer file formats, and save features such as references, table captions and so on.
  2. Can do some basic editing in browser, but open it up in Word/Excel/PowerPoint to do more editing
  3. Supports versioning and ability to share files
Disadvantages:
  1. Need to have a windows live account to use the service
  2. Can't edit the document at the same time. In fact, only one person can edit the document at the same time, so if one of your team members have the document open, you'll have to tell them to close the document.
3. Git
While Git is really meant for programmers, I think that it works great if you plan on using it to keep track of text based documents like LaTeX documents or plain old text files. While getting used to Git may take a while as it is built mostly for programmers who deal with tons of code and like to stare at terminal windows, it should provide a great way of keeping track of progress and merging changes to text based documents.

4. Dropbox

While Dropbox may not be the best alternative if a lot of editing is required, it can be a great way to share files between teams as long as only one person works on the file at one time. If two people upload changes to the same file, Dropbox will just create two versions of the file, which will then have to be merged manually. Nevertheless, Dropbox has some great versioning features, is easy to use and provides quite a bit of storage for free. Plus, it's great for sharing files that won't be edited like pictures and videos, and syncs with the latest versions of the folders automatically instead of you having to get the content yourself.

Watch Cricket Online for Free

Posted on 20:12 by Unknown
So if you live in any country that is not a test-cricket playing nation, chances are good that international cricket games are not shown on your local sports channel. But fear not, thanks to the advent of the internet, there seem to be plenty of places where you can watch cricket online, for free that too!

Here's a list of three websites that seem to be working for the ICC Cricket World Cup 2011 that seems to be going on now:

  1. Cric365.info and Cric365.us -- Seems like this website has several channels so you can watch the same game on different channels and watch it on one that you prefer. I find the ads on this website a little annoying, especially since it often refreshes the page so it starts showing the ads again.
  2. Cricvid.com -- This seems to be the best site to watch a particular game, since it only shows one game at a time as far as I know. But the ads on it are far less annoying than the ones on cric365
  3. ESPNStar site -- Doesn't seem to work in North America though,  but if you're elsewhere (in a test cricket playing nation) then it may probably work

How to Stop Yourself From Getting Distracted/Procrastination

Posted on 18:25 by Unknown
For me, procrastination often occurs as a result of distraction. Although, the distraction is often a byproduct of the difficulty of a task (such as homework/projects), distraction is still the main reason why a lot of work is often left undone. If you're like me and need a little help to keep yourself away from lifesucking websites such as digg.com, xkcd.com and so on... you'll love these little apps which I'm about to mention here. What they do is fairly basic: block the internet. Of course, you could just disable your internet connection yourself, but who has the will power to do that?


Selfcontrol (free; Mac only, Linux alternative here): This app pretty much only does one thing. Prevent you from accessing the internet for a set period of time without allowing you to overrider the disconnect. Essentially, if you have to reconnect before the timer runs out you'll have to change around some system config files. While I've only tried this a handful of times, I'm surprised to say that it does work... but it takes a lot of willpower to click on the start button. Also, it might be a good idea to turn off the iPhone/BlackBerry/other Smart Phone as well, incase you get tempted to use that instead.


Freedom ($10; Mac and Windows): Like Selfcontrol Freedom offers similar abilities of being able to disconnect yourself without an option to reconnect before the timer is done.


While I think that these applications alone may not help you get rid of your habit of browsing youtube videos or checking Facebook videos, they may prove to be helpful when you're really under a deadline and can't afford getting side tracked even for a few minutes.

Using Google Squared to shop online

Posted on 17:36 by Unknown

Google squared is a service that has been online for the past few years. The service allows you to compare several different alternatives for a particular product by showing you the prices and details for a particular product or a range of products.


I find this service to be quite helpful when searching for a particular class of products.  For instance, if I want to check out the latest Android phones all I need to do is visit the site and search for Android phones. Like so: http://www.google.com/squared/search?q=android+phone

Google Squared showing a list of 3 android phones.

The site then shows options for three different phones and allows you to search for more phones that are similar.  You can also add different criteria to the colums and Google would try to find the information for you. For example you can add carriers, or colours or other attributes of the phones you would like to compare like battery life.

While the search feature is not perfect, it serves as a great starting point to get an idea of the different alternatives available to you. Next time you're in the market for new product, particularly a technological product, I suggest you try out Google Squared and see if it can you with helpful information.

Fixing Time Machine Backup Errors

Posted on 20:43 by Unknown
Recently, I had been getting an error from my Mac's Time Machine as follows:

The backup was not performed because an error occurred while copying files to the backup disk. The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk.
That pretty much kept telling me that it couldn't perform the back up.

At first I thought it was a problem with my back up disk as Time Machine had mentioned. So I did the following:
  1. Deleted the Time Machine partition on my back up disk through Disk Utility
  2. Repaired the back up disk
I tried the process again, but it still gave me an error. 

After searching for similar problem, I came across some posts that advised to disable spotlight indexing, but that didn't seem to help. Finally, I stumbled across a post that mentioned the use of the OS X console application to see what was wrong. 

Through the help of the Console application (which can be found in Applications > Utilities > Console), I was able to determine that what happened whenever I started a back up was that it would give me a error message whenever it tried to back up a particular file. Turns out that the file was locked, and could not be copied by Time Machine, so it kept saying that there was a problem with the back up disk.  Deleting this file fixed the problem, and it seems like Time Machine is backing up things just fine right now.

Dvorak typing tutors for Programmers

Posted on 19:52 by Unknown
So, chances are that you have been trying to learn the wonderful dvorak layout, and have found your way to this page. Great!

This "tutor" does not teach you how to type English using the dvorak layout, but rather focus on special characters instead. The sort of special characters that come up often during programming. If you want to get started with typing normal words and letters, you're better off with ABCD or some of the other websites/applications out there. If you don't happen to know what (or who) Dvorak (the scientist, not the composer or ) or the Dvorak layout is, head over to the Dvorak Zine site to find out.

Why use a tutorial when you can learn this by doing some actual programming/designing?
Good question. The answer is because this reduces unavoidable frustration.

Often times when you are programming, its no so much a matter of syntax but rather a matter of algorithms. As a programmer, you tend to focus more on the results rather than the way you get there, and typing then (like syntax) just becomes an intermediary step on the way to the final program (or web-page).



But switching from one keyboard layout to another means that the certain special characters (particularly the semi-colon and the dash) will not be in the same place that they used to be, a problematic side effect for programmers. And when you are trying to program, your fingers will tend to reach for the old locations. Then, you'll have to press the backspace key (or some other key if you happen to be a vi or emacs user) and try again. Needless to say, this whole process gets annoying very quickly, not to mention the fact that it results in a huge productivity drop.

And hence is my reason for creating a dvorak tutorial for programmers. So, it would be wise to only completely switch to dvorak, after you are certain that your hands will go to the right place when you need to type a curly brace.

About the "tutor":
This tutor thing, in reality, nothing but plain ol' HTML page. You can download it to your hard drive and start typing till your get the hang of it. All I have really done is tried to formulate some patterns that come up often, to help your hands get used to reaching the right keys.

Download DVtutor.html (or view it in your browser).

Why should you switch to OpenOffice?

Posted on 19:33 by Unknown
I have always been a Microsoft Word user for a long time, and have used it for almost all assignments and projects (except for the longer ones where using LaTeX was more helpful). But I think now is probably a good time to switch to OpenOffice for personal projects and smaller collaborative projects.

Why so? Recently, I was mailing out some .xlsx files (that is Microsoft Excel 2007 files) to a few people, and wanted them to give me some feedback regarding the contents of the file (the file had nothing special in it, just some numbers and text). But, I soon started getting replies from people saying: "I can't seem to open the file, can you please send me the older version?" Of course! How could I forget that some people were actually still using Excel 2003, and that the 2007 version files won't work for them?

This made me think about the reasons why Microsoft decided to switch file formats. The main reason, I suppose, was to improve the way information was stored in a file. Instead of dumping all the things in one file, it makes sense to separate textual data from graphical data. To see what I mean, rename a .docx file as a .zip file and have a look at its contents. This allows for smaller file sizes, faster loading times and perhaps some other things. The more recent 2010 format is also different from the 2007 one, possibly due to the lawsuit by i4i against some IP infringement.

Another just as important reason for a corporation like Microsoft is revenue. If Microsoft stops innovating, well then they'll go broke pretty soon. More importantly though, with no way of convincing consumers (more so than corporations) to purchase the newer version of the software, profits would slowly, but surely, decrease. One effective way to convince consumers, it seems to me, is forcing file format changes.

One little problem while adding these features is compatibility. First off, if you happen to be using, say, Ubuntu, you won't be able to open any doc/docx files. Sure, OpenOffice tries to open docx files, but the support for this is sketchy at best, after all, only Microsoft (and the Office team specifically) knows how to read the .doc and .docx format. Others can only reverse engineer the format, and figure out a few parts of the puzzle. A bigger problem is compatibility between versions. If I have some conditional formatting (say if the text meets a specific condition it gets highlighted in a specific colour) in an excel spreadsheet on Office 2008 (the latest version available), and I send it over to someone who is using Windows 2007, the conditionally formatting doesn't always work! Sometimes the colours don't work correctly, and sometimes there are other problems.

On the contrary, cross OS compatibility seems to be much less of a problem in OpenOffice, and most bugs (as well as features) are usually well documented. If you need help, or have an issue, you're usually a quick google search away (or sometimes may be a forum question) away from finding the solution. Compatibility isn't much of an issue, because most people running OO.o will likely have the latest software installed (all upgrades/updates are free!), and be able to access the latest file formats. Plus, the files look and work the same regardless of which platform you use!

It seems to me like OpenOffice tries to accommodate users of all operating systems, and has a great community and user base to help you out if you run into problems. Of course, it isn't as full featured as Microsoft Office, or even Apple's iWork, yet, but if many start caring about the software they use I'm sure the project will get there sooner.
