Ever since I discovered Opera Mini, I had installed it on my first mobile (K300i) and now the latest Opera Mini 5 beta is present on my Nokia E51. Few months ago a new browser came up for S60 3rd Edition Mobiles named Skyfire. The main selling point of this browser was almost full support for javascript and Adobe Flash with near desktop experience; which enabled us to watch YouTube videos on the mobile!

I had been using both browsers side by side for a few months now & came to feel that Opera Mini is a lot better for daily use and Skyfire is better for those one off toughie websites that must work with javascript and other stuff enabled.

Here’s an example: Recently, I started accessing my twitter account through Dabr from Opera Mini. The mobile UI rocks and zoom in and zoom out is instant. It happens in the client side. Opera Mini has an intelligent mix of client side and server side operations, whereas, all operations from Skyfire require an active internet connection. At best, internet access from mobiles through GPRS still remains patchy & hence, Skyfire should have that intelligent mix of operations and where possible, operations should be done at the client rather than server.

Opera desktop’s goodness of Speed Dial has arrived on Opera Mini 5. It’s awesome and saves you tons of clickety-clicks, which are irritating on a mobile. The whole menu system has been completely revamped. UI is smooth and fast (which is a downside with Skyfire)!

The best feature of Opera Mini of all is tabbed browsing. That blows away any other mobile browser on the planet. Being fast and loading heavy pages on separate tabs is a pretty awesome thing. By long pressing on a link, you can open them in new tabs inside Opera Mini. Hence, the Dabr + Opera Mini seems to beat any other twitter competition. Saved pages are really saved pages. They can be accessed even when there’s no connectivity.

Recently we had to book tickets to watch a movie at Mayajaal and Skyfire displayed the website amazingly well. Opera Mini suffered there. Similarly, Opera Mini rocks in opening popup windows (when clicked explicitly), whereas Skyfire fails. All in all, if you are going on a long journey with conservative power, Opera Mini is the way to go. Or if you want near desktop experience on your mobile for all websites, then Skyfire is the way to go.

Skyfire Gripes:

1. No tabbed browsing.
2. No landscape view of web pages and videos.
3. Phone heats up after about 15 minutes of usage. Doesn’t ever happen with Opera Mini.
4. Compared to Opera Mini, it is very heavy on battery.
5. No option to logout from your Skyfire account. You have to manually delete the “Preferences” file to logout.
6. The assumption that an active internet connection is always available.
7. Proxy server support and proxy authentication i.e. HTTP code 407. I have been asking this for so long that I’m beginning to feel that this feature won’t come at all.

Opera Mini Gripes:

1. No flash support.
2. Javascript should be supported better.
3. Zoom in to images is dismal. I hope this issue will be corrected when Opera Mini 5 comes out beta.
4. This browser also doesn’t have support for proxy servers and proxy authentication.

What are your opinions on these two browsers? What browser are you using on your mobile phone?

Hey guys, I will be switching hosts today and in the time that the DNS propogates, you may experience a slight downtime. Kindly bear the same. Thanks.

I’m a big fan of Dev Opera Articles. They have some excellent articles on HTML, javascript and all things web.

The biggest problem is that, their RSS feed doesn’t give the full content. Everytime new articles show up, I have to visit the website by clicking the link on the RSS feed. It soon got very frustrating.

So, here’s the result – http://feeds2.feedburner.com/DevOperaFullFeed. That link contains the RSS feed for Dev Opera Articles in full. That is, there are no one liners any more. This feed will give you the full content of the articles present on the Dev Opera’s original feed. Subscribe to this feed and live happily ever after

Skyfire 1.0 is the new kid on the block in the mobile browser war. Its not a kid per se but there are some big boys like Opera Mini and Opera Mobile who don’t give up all too easily. I have been a beta user of it from India since 0.6 and it was fun all this while to keep track of this superb browser. Their main aim is to bring desktop like browsing experience to the mobile browser and they are almost there. So near, yet so far.

Like all other reviews about this browser until now, its safe to tell that it is able to play flash videos pretty well inside the small screen. Here are some notable differences between the earlier betas and this 1.0 version:

1. While watching any videos on youtube, my Nokia E51’s rear would just heat up quickly & few minutes down, it would be difficult to hold the phone. This problem has been nearly solved in 1.0. That’s possibly due to power optimization techniques.
2. When you scroll very quickly on long web pages, Skyfire usually shows a checkered screen with gray squares (screenshot below), which disappear as and when content appears. Pre 1.0, this checkered screen would take a long time to disappear. With 1.0, this problem has been solved. Same problem used to occur during zoom in/out. Now zoom happens at blazing speed. Neat!
3. 
4. Its able to handle basic javascript very well. For e.g. its able to display the hover menus that are present on top of my blog. Its also able to show alert boxes.
5. Video quality is maintained even during zoom in and zoom out. This was a major drawback in pre 1.0 versions.
6. The initial loading and shutdown of the browser would take a long time in pre 1.0 releases. Not so in this current release. This has been drastically improved.
7. File downloads happens excellently. Kudos for this. This is a major drawback with the E51’s native browser.

This one could save you lot of time In short, the answer is to “return false;”. That’s it. If you want to know more details, read ahead.

Say, you have an awesome page where you want to disable right click and also disable Ctrl+C (copy), Ctrl+S (save page). The process is simple. Just register an event for right click and when the event fires, just return false. Since false is being returned, the browser will cancel the event.

Same goes with keyboard. ‘onkeypress’ event is fired whenever a key is pressed. To reject any key, just capture that event and return false. If you want to do anything special, just do it before returning false. Ctrl+S is interesting. In most web browsers (notably google chrome), it brings up the default Save Dialog. Most web apps have keyboard shortcuts these days & oh! 99% of them don’t return false, only to find the user experience irritating when the save dialog pops up; when something else should occur. Hence, if you wish to customize the functionality of the default browser specific keyboard shortcuts, do the following:

1. Create an event handler and capture the event.
2. Do something.
3. “return false;”

That’s all. Have fun!

Here’s the trick below to open multiple gmail accounts with the same version of firefox.

1. Open the Run dialog. In linux, press Alt+F2. On Windows, press WinKey+R.
2. In the dialog box, type “firefox -p -no-remote”. This will bring up firefox’s profiles dialog box.
3. Click on “Create Profile” and follow the wizard. Lets assume you named the profile as “gmail2“.
4. Now close the dialogs and return to desktop.

Now, open the Run dialog again. In the dialog box, type “firefox -p gmail2 -no-remote“.

“-no-remote” option is very important because it creates an isolated session that is different from the currently open firefox windows of other profiles. If -no-remote option is not given, then a new window of the currently running profile or the default profile is opened, where session sharing happens (which we don’t want).

Now, since sessions aren’t shared between different profiles, you can open two accounts and happily have them.

Suggested Improvement for Firefox:

Internet Explorer 8 has this amazing option in the File menu where you can open a completely new session of IE. Sessions are completly isolated and gives lot of relief. Its available at File->New Session. Hope this feature is brought into Firefox as well. Or if this feature is already available as a plugin, please let me know in the comments. Actually speaking, this feature was available in IE since IE 6 (AFAIK). In IE6/7, you can open a completely new session by clicking the IE icon on the desktop.

Ever since Gmail launched its Gmail Lab, I have been its fan. Some of its features are so awesome I use them day in and day out. Mentioned below are my favourite lab features:

1. Go to Label

If I were asked to pick one best lab feature from all of them, this would be it. I have set up filters extensively to mark labels to most of my emails. I’m also a keyboard shortcut junkie & expect web apps to have keyboard shortcuts. Retrieving emails based on a given label had never been this easier. Just type ‘g‘ followed by ‘l‘. A small dialog opens and offers suggestions as you type the label names. This is an awesome feature that saves loads of scrolling and clicking.

2. Search Autocomplete

This is an Excellent lab feature that was announced yesterday. I have enabled it and searching mail using its operators has been made very easy. This also offers suggestions from your contacts as you type. For each letter that you type, if there’s an available search operator, it lists that as well; neatly separating the operators from the contacts with a black line.

3. Tasks

Less is more. This tasks features offers very little features, almost mimicking it to a paper to-do list. Just list the tasks and strike them as you are done with it. There are of course some advanced features tucked in. But they don’t appear at first sight. This is a well executed Labs Feature. There are times when you do not need a full blown task manager & this feature comes in handy. I hope they bring this feature to their gmail mobile app.

4. Youtube, Picasa, Flickr Previews

Recently, I have been trekking/touring a lot. People from the trekking gang send emails with links to Picasa/Flickr albums. They also add youtube video links to the email because there’s no way to actually embed a video inside an email. With this labs feature, I’m able to enjoy all the related photos/videos in one place. Really cool.

5. Quick Links

This is one awesome feature. Many months ago, I posted a question on a mailing list asking for suggestions for buying wireless routers. After a week since the discussion, I was searching high and low for that email but couldn’t find it. Lots of people had given valuable suggestions and how can I lose them all? As soon as I found the email, I activated this quick links feature and clicked on “Add Quick Link” button in its dialog box. Voila! Now I can reach this email directly with a mouse click. 

There are also times when I search for “in:inbox is:unread“. This search operator retrieves all mails in your inbox that have not been read yet. I didn’t want to type this operator every time to check for unread messages that are buried somewhere. I just added a Quick Link for this operator and now its just a click away. Happy times!

Two days ago, as I switched on my computer, I got this error message; “A disk read error occurred. Press Ctrl + Alt + Del to restart”. It is the dreaded Black Screen of Death. The most probable reason for this message is that the hard disk on which the computer is booting would have crashed or its in the process of crashing.

The best you *must* do at this point is that, remove the faulty hard disk, connect it as a slave to another computer and take backup of all data. After data is safe, you can try and find out the point of failure. After all, that error message doesn’t necessarily mean that your disk has crashed.

Probable Points of Failure

1. The bus connecting the hard disk to the mother board is faulty.
2. The master boot record (MBR) on the hard disk got corrupted.
3. SMPS (Switch Mode Power Supply) failure. In this case, your computer may not boot at all. But there are times when only one of the power plugs may fail.

If anyone has encountered any other points of failure, please let me know in comments and I will add them here.

Answers

1. For the faulty bus, you can grab another bus cable from the secondary drives, connect it to the mother board with the faulty hard disk and try booting. If it works properly, head straight to the electronic store to get a new cable.
2. To replace the corrupted MBR, pop in your operating system’s installation CD/DVD and follow the on-screen instructions. For Windows, boot in from the installation CD, press ‘R’ for recovery console, give your administrator password, and type the following the commands: fixboot, fixmbr. For linux, you must reinstall the boot loader (grub). Restart the computer now. If all is well, it should reboot properly.
3. Remove the power plug connected to the faulty hard disk and connect one of the other plugs that are attached to the SMPS. Reboot the computer now and try.

In my case, my hard disk had crashed. But thankfully, I had proper backup of all data.
