Technology and You

I had to get a folder out of my father's old computer. The constraints were:

• Windows 95
• No USB ports 
• No Internet connection (the modem refused to connect to the dialup connection due to disturbance in the phone)

It's been quite some time that I posted an entry, and a LOT has changed - so I thought I'll update you on what has:

• I have shifted completely to Google Chrome - a move that surprised me most of all. Firefox has a lot of features, but the toll that the extensions take on speed make the breezy Chrome a winner. You can shift to a developer version of Chrome (brand new features, but a little unstable at times), by downloading this. Now if only Chrome would do a better job at handling PDFs
• I have an HTC Magic - my first Android phone (yay!). Again, being a die-hard Nokia fan for the last 10 years, this paradigm change was not without trepidation. However, Android is where all the action is. And with the Google's own Nexus One now available, things are getting very interesting.
• I don't play the Wii as often as I thought I would. It still pops up into my head once in a while, but then its too much of an effort to set it up. I'm still intrigued by Super Mario Galaxy 2.
• Similarly, I've stopped spending time with Linux and Ubuntu - something I regret, but have no time for - thanks to my desk job :(
• I now use a Blackberry and am disgusted with the quality of the handsets. There is no <3 in BB handsets, and its sad. It doesn't even excel in being utilitarian 
• I'm off Facebook (good riddance, I say) and on Twitter (follow me @rohan_dayal) posting pictures from my phone. 140 chars is more than I need to express myself (haha!)

Yet, some things remain the same:

• I'm still wary of the iPhone and all things Mac (though it is gaining mass acceptance all around me)
• I still support open source (VLC, I'm looking at you)
• Google continues to be the company I admire the most (no surprises there :D)

What's up with you? Leave a comment.

I was quite surprised to read about an Easter Egg cheat code in Minesweeper - the game I thought to be the most simplistic and innocent ever made. TechRadar has an interesting post on the history and success of Minesweeper.

The cheat code is as follows (and I quote):

Load the game, type 'xyzzy' and press the left shift key. Now, watch the very top left of your screen. When your mouse cursor hovers over a safe square, you'll see one single white pixel. Move over a mined square, and it becomes black. It's an eyesight-killer of an easter egg, but an excellent way to impress your friends.

Reminds me of the good ol' Konami code. If "up-up-down-down-left-right-left-right-A-B-A-B-Start" holds a special place in your heart - leave a comment :)

Announcement of Samsung's I7500 Android-based phone  led me to pen down what's been on my mind for quite some time. I was disappointed to see that a QWERTY keyboard was missing. 

And over the last few months, I was disappointed to see Nokia's attempts at catching up with Apple - the Nokia 5800 Xpress Music and the E75 - choosing to go with no QWERTY and a numpad+flip QWERTY keyboard combo, respectively. E75 would have been the phone to replace my E61 had it not wasted precious front face space in the numpad, which can easily be enabled through a virtual keyboard on the touch screen.

So what am I getting at? The perfect mobile phone form factor (IMHO) is out there but refuses to catch on. The Android-based HTC, T-Mobile G1 has not really picked up - most hardware reviews say that the phone is great, but it is not a 'finished' product yet. The recent 'cupcake' update should enable a virtual keyboard for quick 'one-hand' use and the G1 already has a QWERTY keyboard for when you want to write a complete email.

Sadly, I still have not seen/used a G1 in real life. I have a feeling that a thin fully capable (preferably multi-touch) touchscreen phone with a slide-out horizontal QWERTY keypad will be the form factor that everyone settles down with. Is anyone at Apple/HTC/Nokia/Samsung listening? When will I get my dream phone?

I have lost count of the number of times I have been asked for advice on buying a phone. Unfortunately, a phone is something very personal. For example, I can't stand typing on a touchscreen with a stylus, whereas I have seen a friend tap away an entire business mail with her stylus. I would rather not have a camera in my phone - it just increases the cost and is of no use when you really need it, I'd rather have a full featured camera. Others (are you one of them?) swear by their tinny (sic) phone cameras.

Of course, this does not mean I send my friends away without any advice. Here is my 6 point phone buying howto:

1. Make a list of the features you must have (examples are camera, mp3 player, etc., if you are a mail user, a QWERTY keypad is highly advised)
2. Make a list of features that you do NOT need (does anyone use GPS for any other thing apart from showing friends how cool it is to know exactly where you are - something that can be done quite accurately by Google Maps for Mobile for free)
3. Decide on your budget - Something above which you will not go even if you find the phone of your dreams. The iPhone is NOT the phone of my dreams, but I still will not spend the tonne they demand for an unlocked phone
4. Go over to your neighborhood phone seller. I find that visiting the same guy can get you a discount. Don't go to too many places - there is little variation in phone prices. Don't look for phones online - you might miss the great phone that is meant for you, you may not get the best deal or the phone may not be available immediately
5. Ask the dealer to show you the most popular phones. Start giving feedback - I like this feature/Is there something that does not have this feature/Is there something that has these things but is cheaper? - refer to the lists you made earlier. You should soon converge to the phone that best suits your criteria
6. See if you can use the phone once and test its user interface before you take the plunge. If I had known the amount of trouble the switched options and exit keys would have caused me, I would never have bought the Motorola Razr

I have found the Nokia phone selector to be useful in the past. You can shortlist phones based on the features that you want. Of course, that's because I'm a Nokia fan and don't look beyond that.

Been on the receiving end of this advice from me (or not)? How useful do you think it is? Let me know by leaving a comment.

Its no big secret that I have been a big fan of Firefox. I have been using Firefox 3.0 beta 5 ever since it got included as the default browser with Ubuntu 8.04 (Hardy Heron). Needless to say, I was quite impressed with the new avatar. Ars has a great series of articles that cover the new features introduced in Firefox betas. However, the Linux interface had not changed much from Firefox 2.0.

Today, I was forced into trying the beta in Windows (yes, it's been that long since I've had to use a Windows maching on a regular basis). On one side, I'm disappointed by why a major interface overhaul was not included in the Linux release. On the other hand, I'm practically smiling with joy looking at the pure aesthetics of this release in Windows. The Forward/Backward button integration, the enhanced address bar, the default navigation buttons, the screen preview of text/graphics selected and dragged - wow! (Read this article for a summary of the changes)

The browser is said to be using significantly lower memory than previously releases, and is really fast. And the browser has not crashed on me even once (though, I have to admit, I have not exactly stress tested it yet).

You can download the beta here. As always, the normal warning of beta releases apply - don't use it for anything critical (like share trading, bank transactions, etc.), and don't blame me if anything goes wrong.

Scientists in UK claim to have effectively solved the traffic jam problem. Their simulations show situations where traffic slows to a crawl with their being no real obstructions in the road. From this press release from the University of Exeter:

The team developed a mathematical model to show the impact of unexpected events such as a lorry pulling out of its lane on a dual carriageway. Their model revealed that slowing down below a critical speed when reacting to such an event, a driver would force the car behind to slow down further and the next car back to reduce its speed further still. The result of this is that several miles back, cars would finally grind to a halt, with drivers oblivious to the reason for their delay.

More importantly:

When you tap your brake, the traffic may come to a full stand-still several miles behind you. It really matters how hard you brake - a slight braking from a driver who has identified a problem early will allow the traffic flow to remain smooth. Heavier braking, usually caused by a driver reacting late to a problem, can affect traffic flow for many miles.

What's surprising is that UK which has such a well-managed transport system has researchers optimizing it. I wish someone in India could do the same. I don't even need Google Map Traffic to know that most of Delhi's (only for example, the situation is the same across most metros) roads are clogged everyday during rush hours.

Bear with me as I offload some of my frustration after another endevour across Delhi roads. Now, I know that driving home after a hard day's job is a daunting task. If possible, try practicing these trips the next time you are in a traffic jam:

• Prepare ahead - You know how much time it takes going down that road every day. Compensate for the time. Try leaving before or after the rush hour. Let people at home know that you are going to be late so that you don't have to rush.
• Choose your car wisely - You spend up to four hours in it every day. Go the extra mile and choose one that you love and enjoy being in.
• Make it comfortable - Dish out the moolah to get comfortable seat covers (and a neck support if you like it). Find the angle that you are comfortable sitting in. Spring for a state-of-the-art music system. Buy/burn music that you like and keep a collection of feelgood music handy. This will ensure that you remain entertained along the way and are not quick to loose temper. Trust me, it's worth the extra money. I'll be glad to offer suggestions.
• Try forming a car pool - And not just because you'll save petrol. Hopefully, you'll find someone interesting to speak to during the way.
• Try different ways of going home - Maybe, you'll enjoy a change in the scenery/buildings.
• Keep your cool - Feeling too tired? Stop at a coffee shop on the way and reload on caffiene.
• Don't make sudden changes in your driving pattern - Comes directly from the advice of the scientists in UK. Makes for a better drive and avoids traffic jams. Also, try to anticipate changes that others make and gradually adjust your driving.Be compassionate - Let ambulances and police cars through.
• DRIVE IN YOUR LANE - If there is one thing that you should take home, it's this. Changing lanes does not help. Movement of traffic is usually cyclical. Unless you are stuck in a lane for a long time while other lanes keep on moving (implying that there is an obstruction in your lane) try being patriotic to your lane for a change. More often than not, you will notice that just after changing your lane, traffic appears to advance in the lane you were in. Also, if the person in front of you stops to take a turn - wait! It's easier, and less disrupting than forcing yourself into another lane and becoming a public nuisance.
• Smile - Last but not the least. Smile condescendingly at people becoming public nuisances. Smile at someone who gave you a chance to enter a lane to know that they are appreciated. Even smile at the cabbie who butted into your lane. He might be having a bad day.

Another gadget that has caught my fancy of late. Digital photo frames let you display slideshows of your digital photographs. You can just pop-in your camera's SD card, store photos in the internal memory - some models even let you connect to your Picasa/Flickr account through WiFi and stream your photo-album. You can even play movies and MP3 songs. NYTimes created a comprehensive feature comparison chart here that you can choose to select which one is best for you.



Very convenient, very stylish - they look just like contemporary photo-frames. They're available on Ebay India now, though I have not seen it at any retailer. I think it'll make for a great gift too.

So my prediction does come true, albeit, not entirely. Almost two years back I had written about why Google should acquire Goowy. According to TechCrunch, AOL acquired Goowy on Monday, February 4, 2007. It seems that Microsoft's bid to takeover Yahoo has caused some stirring in the market, as a lagging AOL seeks to add some bling to its suite of services.

Goowy is a flash-based "online operating system" if you will - giving you access to basic apps (like email, messaging, online storage, etc.) with a personalized interface wherever and however you login. This basically meant that as long as you had a Flash player installed, you could login from whatever browser and platform, and you'd always get a familiar interface. The webmail is not a pushover either. Goowy's email app provides features that were similar to Yahoo's beta interface (drag-and-drop, etc.) and was launched much before the latter.

Back then when I reviewed it, I was quite impressed with Goowy. Will Goowy die a slow death just like Netscape, which was acquired by AOL and subsequently axed? Or will Goowy bring AOL back into the limelight? Only time will tell. What do you think?

EDIT: Thanks to David for pointing out that Winamp is alive and kicking. It went through a slump in 2003-2004 (as reported in these articles), but since the release of version 5 has regained its share in the limelight. I'm happy - Winamp was my first music player too :)

Finally, something to be excited about. One of the essential requirements in any analysts job is to create charts. However, I find manipulating Excel charts a bit too tedious (most options are hidden inside too many menus). Here's a simple solution: Google Charts API. All you need to do is create an image url that includes the chart options and your data, paste it into the address bar of your browser, and your chart is ready. This means that you can embed charts that are created on the fly directly into a webpage/document/presentation. Here are some examples of the charts that you can generate and the corresponding URLs in green(note that these are not static images, they are created along with this webpage):

chs=150x100&chd=t:100,80,60,30,30,30,10&chtt=Sample Chart


Of course, numerous tools for creating charts using this API have already sprung up. Amongst the official list, I found the Visual Google Chart URL Generator to be the most intuitive (though it does not support Venn diagrams). Another good interface is provided by the Online Chart Builder. You can plot basic mathematical functions using Plot Function Google. For the security junkies, the FAQ states all data used for generating the chart is purged within two weeks.

The icing on the cake: The default color pallette is pleasing to the eyes. So you can worry about getting the data right and leaving the aesthetics to the API.

Another freeware solution to creating charts on the fly is JFreeChart, an open-source Java based library. A good paid and very flexible alternative I have used is Tableau (thanks to Pratik for pointing that out).

Is it time to say goodbye to Excel charts? What do you think - leave a comment.
