Having switched from a desktop to a notebook as my primary computing device (not considering the PS3), being conscious about the added vulnerability of personal data is now imperative. It would be terrible if the laptop was lost or stolen, of course, but there is now the more probable risk of accidentally damaging the portable machine (not that I am sloppy, but it is reassuring to know that I am protected from hard drive damage due to dropping the laptop, or from accidentally yanking it off the coffee table).

Some habits are really worth adopting in order to minimize the pain of going through data loss and/or recovery - even more so in the case of theft (fact: about 97% of stolen computers are never recovered). There are scores of data recovery services available, but they generally seem to take advantage of the customers’ cornered situations and charge a heavy premium for fetching data from a damaged laptop (often more than the cost of a new computer). Of course, there are some pre-emptive solutions available such as PCPhoneHome or LaptopLocate.net, which can help track down machines by monitoring their location. With the iAlertU freeware application, you can even add “car alarm” or security camera protection for an iSight-equipped Apple notebook.

The first and most vital thing to do for any computer user, is to use a backup storage device. The simplest form of this would be to connect an external hard drive. Hard drives with encryption features allow locking down of personal information as all data stored on the drive is inaccessible without a master password. While it is possible to back up data on optical media like DVDs, this is a cumbersome repetitive chore and requires a lot of sorting and organization for the backed up information to be easily accessible.

External drives can play well with automated backup software, thus making what would otherwise be a daily chore an invisible background task for the computer. My external hard drive is network-attached, which eliminates the need to constantly plug it into a laptop, and additionally allows moving all media files to the external drive so they are accessible from all shared computers on the home network. On the flip side, this does have the disadvantage of not being able to access your media outside the home (unless you open up the drive for internet access).

I often find myself minimizing the kind of personal data that is stored on the notebook’s hard drive. I typically use my Gmail account as a network archive as this makes my files retrievable from any computer with an internet connection (more on how to make this process more convenient in a future tutorial). This benefits both security and accessibility, and prevents losing years of data and pictures along with the laptop. There are new web services cropping up now, that recognize this activity and endeavor to help organize data tucked away in your email attachments. Xoopit is one such service that ties in with a Gmail account.

What is your favorite strategy?

When my wireless router started faltering with alarming regularity in the past month, I realized the little device had probably reached the end of its life cycle. The Netgear router has been pretty much running 24/7 over the past two years, and while routers typically last much longer than that, everyones mileage varies.

Therefore, instead of shopping around for an alternative el-cheapo router that would get the job of letting all of my wireless-capable devices talk over the internet done, I decided to take this opportunity to upgrade all the way up - to an Apple Time Capsule.

If you’re familiar with Apple hardware, you will realize that the Time Capsule breaks no new ground - it is simply an 802.11n Airport Extreme base station with a built-in hard drive, which is also its biggest plus point. Having switched from a desktop to using just a notebook computer, a new Macbook Pro, I quickly found the need to have a wireless network hard drive solution quite imperative. It is tedious having a backup drive that constantly needs to be plugged in, to be of any benefit. The Time Capsule steps in with network-attached storage (with choices of 500GB and 1TB), and also integrates seamlessly with the one-click Time Machine backup feature built into Mac OS X Leopard. Additionally, the Time Capsule can also connect (and extend wireless capabilities) to a USB printer or external hard drive. I picked up a 500GB Time Capsule, because the storage capacity should meet my needs for now. There are also web tutorials that prove it is quite simple to upgrade the internal hard drive yourself.

I was a little concerned about rushing out and buying a Time Capsule, simply because initial reviews of the hardware have not been excellent on the Apple website. People have voiced concerns about Time Machine backups taking exceptionally long durations to complete, impact on wireless browsing performance while backups are running (forcing them to turn this off while actively using their computers), and other issues such as unusually high heat generation and wireless device incompatibilities. Having read through all these reviews, I was prepared to purchase the Time Capsule in test-drive mode, ready to return it within the 14-day period if any such issues would raise their ugly heads. Thankfully, I am extremely happy with my Time Capsule.

I have not run into any speed or wireless bandwidth issues while running Time Machine backups or generally accessing the wireless drive (I did use an ethernet connection to perform the first backup, as most would recommend). The router functions excellently, plays well with all my devices, and efficiently utilizes my high-speed connection. I have not experienced overheating issues either, although a higher heat profile is not very unusual for a NAS/router appliance.

The Time Capsule also interfaces very well with my Playstation 3. This was a very important requirement for me, as the PS3 is used heavily as my media center and not just a gaming console. Speaking of games, the console has not seen any connection issues (that I had started experiencing on my earlier router) while playing online first-person shooter games. Additionally, media streaming from my computer to the TV via the PS3 has been excellent (I use MediaLink ($20/free demo) and Mediatomb (free, open-source) for wireless streaming from Mac OS X to the PS3). One thing to note, is that the PS3 does not recognize a NAS - it only supports the DLNA protocol, and would require a computer that is running a media server application in order to access media files. The Time Capsule does not support direct Universal Plug-and-Play (UPnP), so if any of your devices require this protocol the Time Capsule is not an option for you.

The Time Capsule only requires a couple of screens of configuring the first time it is used - this is done via the Mac OS X Airport Utility. Once this is done, the router is ready to serve Mac, Linux and Windows machines. The Time Capsule hard drive is also directly accessible by Windows machines, which see it appear as an encrypted, password-protected drive on the network. There is an Airport Admin Utility available for Windows that should allow configuring the Time Capsule using a Windows machine, although I have not attempted this (yet).

As it supports the 802.11n standard, the Time Capsule also allows me to fully utilize the wireless-N capabilities of my notebook. While this does not mean much for casual browsing, it does allow better local networking and is future-proof as far as wireless standards are concerned (at least for a good while).

American Express is one of the major global financial service providers and is best known for its credit card and traveler’s cheque businesses. Naturally, I was shocked to learn that the 74th largest company (Fortune 500, 2007) has such poor focus on enhancing user security for its financial account portal.

The AMEX website permits users to only set passwords with a maximum of 8 characters, with no non-alphanumeric characters supported. This is very strange for a corporation the size of American Express, and especially so for a financial services company. I figure that with these constraints, any kind of password set up on the AMEX site will only qualify as having “weak” strength.

However, I’m sure most people would not even encounter these constraints while selecting their passwords. In a study on password security conducted with undergraduate and graduate students, it was found that over half of reporting users (52.70%) never change their passwords if not required by the system. These numbers drop with increasing frequency, with about 12% users changing their password every three months.

Furthermore, some common practices have been observed to be followed by users when choosing a password. Most users only use a combination of lower case letters and numbers, where the number is usually a personally meaningful one (such as birth dates or phone numbers). Over half of all users also reported using the same password for multiple accounts (around 33% use some variation of the password).

With most websites (AMEX, for example) not enforcing stricter rules for generating passwords, user tendencies are not going to see much change. Passwords are generally considered a pretty basic form of security themselves, and therefore one should be very careful in selecting a password that effectively appears as random as possible to a potential intruder.

Password strength is the amount of security that a password can provide against password-guessing attacks, and is measured in bits of entropy.

Common guidelines for choosing good passwords, as listed on Wikipedia are:

* Include numbers, punctuation, and upper and lower case letters
* Use passwords with at least 8 characters
* Avoid passwords based on repetition, dictionary words, letter or number sequences, usernames, or biographical information like names or dates.

Wikipedia also lists some examples of weak and strong passwords (which are probably already included in password-cracking databases, so please don’t choose one of them for your own).

General alertness is also of extreme importance while using online portals, as even the strongest passwords are of no use when it comes to protecting users against certain forms of attacks like phishing or keystroke logging.

A very special event took form this past week, in celebration of Valentine’s Day. Some guy grabbed credit for making the first ever lolcats proposal (propozlol?).

Oh, and she said yes, lolcats style. =^-^=

A dear friend just emailed me an excellent (and very creative) slideshow, which chronicles some capers his fiance and he have shared in recent years. This presentation also doubles as an invitation - they are getting married by the end of this month (congratulations!!). Sadly, I won’t be able to make it to the wedding that will be taking place halfway around the planet (I’ll get my dinner treat later for sure!). I’d have loved to post this awesome presentation here online, but I’m pretty certain it comes to me accompanied by limited copyright.

Onto the technical part of this blog post (oh yeah, there is always one, isn’t there!)- the slideshow file that I received (in the PowerPoint Show, or .pps format) is not natively playable by StarOffice. While it is one of the better open source application suites available today, StarOffice does fall short in cases such as this one. Fortunately, Microsoft has been graceful enough to offer standalone viewer programs (on Windows) that can handle Microsoft Office formats - not only for PowerPoint (2007), but also for Word (2003) and Excel (2003). There is also a compatibility pack available, which enables MSO 2003 viewer programs to handle MSO 2007 file formats.

By the way, if you have not heard of (or recently taken a look at) Sun’s StarOffice or its parent, OpenOffice, please do. They are excellent substitutes for Microsoft’s commercial Office suite, and have equivalent programs that look and feel almost the same. They can also handle about ninety percent of the functions that the average user requires from their productivity applications suite. Of course, both come at the low, low price of $0.00. StarOffice is also offered via the Google Pack, a convenient package manager tool. For the Mac platform, there is a derivative of OpenOffice available in the form of NeoOffice (with a full Aqua interface).

Now, if only Microsoft gratuitously extended this service for Microsoft Project files, I’d be a happy camper (sigh).

I just signed up for Jaman, a service that brings people access to movies from around the world, including Bollywood. The website attempts to build an online community around its large library of independent and international feature films and documentaries. Jaman was founded and is currently led by Gaurav Dhillon, the former CEO of Informatica Corporation - a company that provides data integration and delivery services. The name Jaman has been derived from the Hindi word Jamun, a tree and the purple plum fruit of the same name that it bears.

My first impression of Jaman’s website has been very favorable - it sports a polished, yet lean interface that is careful not to over-indulge in cliched Web 2.0 design elements. The movie catalog is easy to browse and is neatly categorized by genre, geographical regions, and ratings. Jaman also has a neat movie discovery feature that allows you to tune your preferences in order to find a movie to watch - complete with an ‘I’m Feeling Lucky’ button, as made famous by Google.

Jaman is however, primarily a movie rental service that employs its own DRM and P2P network platform that enables users to rent and watch movies in high definition on their Mac OS X or Windows computers. While the site is free to browse, the Jaman player needs to be installed in order to watch licensed movie titles (which come in at $1.99 for a 7-day rental, or to purchase for $4.99). New users get three free ‘movie tickets’ when they sign up, which can be applied towards rentals. You also get two free tickets for every friend that you introduce to Jaman (so please do let me know in the comments if you intend to sign up after reading this, and I’ll email you an invite :P)

The Jaman team has also developed an unofficial AppleTV plugin that lets you stream content from your computer to the TV (if you own an AppleTV, of course). While the AppleTV has received a tepid response thus far, that scene has been predicted to change come January, once Apple announces their much-anticipated movie rental service via iTunes.

I previously mentioned that Jaman has built a social network around its media collection - this network enables users to get in touch with other movie buffs who may share common interests, fans, as well as filmmakers. People can also submit and share their original professional-quality content for distribution via this channel.

I have to mention Bollywood too - while Indian filmmakers and movie studios are waking up to the command that Internet audiences have in terms of bringing in revenue, Jaman is perhaps the first to offer audiences access to (a few) Bollywood movies on the Web. Zeroing in on the Bollywood section on Jaman, I see about 48 movies currently available - these range from the 70s (like Sharmilee) to contemporary releases (like Black and Paheli). Hopefully, this section will grow over time as more people start using the service.

Unlike other free and commercial offerings on the Internet for video consumption (such as Babelgum, Hulu, Joost, and a slew of others), Jaman is focused on providing a Web-based alternative to the Hollywood-dominated mainstream, and simultaneously improve the meager percentage of world cinema that is available to movie enthusiasts in the US.

I think I shall use my first free Jaman movie ticket to watch Inside Iraq: The Untold Stories, a film by citizen journalist Mike Shiley.

Especially motivated by the recent firmware update rolled out by Sony, I spent most of my available time this past week trying to get a robust media server running on my home network, and it was not quite the simple task as I had hoped it would be. Hence, I felt the need to document some of my learnings and findings here (so someone else trying this setup can hopefully save a few minutes).

All of my photo, audio and video media files live on an external hard drive connected to a Macintosh, which is not in the same room as the TV and PS3 - hence the primary need for a wireless media server. The Mac has yet to be graced with a single full-function UPnP server utility that is easy to setup and configure - this is just a matter of time, however, as I hear that Nullriver is working on developing a PS3 version of their very popular Connect360 program (which plays excellently with the XBox 360).

I have tried pretty much every available Mac/PS3 interconnect solution out there, at least the ones I could try first before buying (which ruled out EyeConnect). I did find reasonable success with Twonky Media Server (30-day demo, $40 license), although this (rather detailed) post is all about MediaTomb - a free, open-source UPnP server application that meets most (if not all) of my needs as far as a wireless media server are concerned.

Sony rolled out a firmware update for the Playstation 3 this week, which added enhanced media playback capabilities (specifically, DivX and VC-1/WMV support), and Profile 1.1 support for Blu-ray discs. An interesting feature that was thrown into the mix, is one that enables players to change the tone of their voice during online multiplayer gameplay. It seems like there will be a few more Darth Vaders joining the network now.

I have been trying to get a home media server set up and running to take advantage of these new features (and the media capabilities of the PS3 in general), but that task has been not so straightforward as I first believed (since I am looking to stream from the Mac platform). I will try and document my findings on that soon.

I came across an interesting feature while reinstalling Skype on my notebook computer - one called Skype Prime. This program is a (relatively) new addition to Skype’s family of services, and like most things Web 2.0, is still in beta. Apparently, the feature has been available since March this year, although I didn’t hear or see anything about it until today. This service uses the tag phrase, “Get paid for sharing your skills, or learn something new”. If you guessed paid phone services, you were quite right.

Skype presents you with an opportunity to earn (big bucks?) by letting you create your own personal ‘call center’. Anything that can be taught over the phone, is up for the offering. You could teach people a new language or narrate horoscopes, while charging them a fee (either per-minute, or a one-off charge). People who call in to avail of your services, will need to use their Skype credit to make payments - the minimum per-minute fee for any service is €0.10 (although that could possibly drop further in the future, as people start seeing greater value in having or providing such a service online, instead of setting up toll-access lines the conventional way).

Just a little online investigation regarding the marketability of this program has me convinced of its value. People are already familiar with the concept of being charged for receiving answers to their questions and problems online (through the popular Yahoo! Answers marketplace). I can easily see someone add the sentence “Call me on Skype if you need additional help with installing your new router (for example)” to their Yahoo! answer.

All this has me thinking.. how clichéd would it be to set up my own personal tech support line as an experiment? Riiight, an Indian guy on the line here on Skype too? At least I’d be charging less than your ‘friendly neighborhood‘ Geek Squad. Thank you, come again.

I snapped this picture at a local grocery store, where a kiosk’s sole function of displaying catchy ads for coupons and new products was marred by a familiar Windows error, although not quite as attention-grabbing this time as the other one I had blogged about.

(click for larger image)

Interestingly, the command line reveals that the kiosk runs Laplink Everywhere, commercial software that allows remote access to a PC from anywhere. I guess all the kiosks from the store (and across the country) connect to a central machine that selects the advertisements to be run by the store, and thus rely on 24/7 internet connectivity for their operation. Given that the kiosk is using a capable machine with a complete Windows XP installation, I would have guessed that a better design would be to run local custom software and just provide daily (or even hourly) updates via the internet connection - which is also the way most Windows spyware work.

Of course, capital costs could have been cut significantly if the kiosk ran cheaper x86 hardware with a basic Linux installation - although I wonder if that was even an option considered by the company that designed the kiosk.
