BarCamp Kerala 5 took place at Technopark, Trivandrum. I attended and even managed to handle a session at the event – here are the slides…

Unfortunately, the slides make little to no sense without me in front of them, yapping away. But still, try and enjoy the pretty pictures.

Nexty is an easy to use To Do list manager created using GTD principles. The core idea behind this software is simplicity. I wanted to make a GTD tool that is the most easy to use. So far, I have released this two times – first when Nexty was created – and then when it was available as a online service. Now, I am giving Nexty its own domain.

Features

Some features that make nexty special…

Easy to Use

Using Nexty is very simple – you can start using it without any trouble

FREE!

Its ‘gratis’ – you don’t have to pay to use it.

Open Source

Its ‘libera’. Since Nexty is published under the BSD License, you can download and modify the code to fit your need.

Calendar

See all your tasks, reminders and due dates in one centralized location.

Next Actions

Focus on one single task at a time using this feature.

Search

For Projects, Tasks and Reminders that you have created.

And the Usual Stuff…

Nexty has everything you would expect in a GTD system – Projects, Contexts, Reminders – you know – the works.

Free Software

If you are using Nexty as a locally installed application, there is no need to worry – the source is available for download – and its still in the BSD license. That will not change.

But if you are looking for a free online GTD tool, try Nexty.

Support

Further development details and announcements of Nexty will appear on its own development blog.

If you need any support for using Nexty, post a query on the Nexty Support Forum.

You can also post your suggestions there as well.

Publicity

I am trying to get some publicity for Nexty and its launch – if anyone has any suggestions about this, your comments are welcome.

Following the release of Firefox 3, I have updated my URL Lister firefox Add-on. Now it works in Firefox 3 – and I have added a new feature.

For those unfamiliar with URL Lister, its a firefox add-on that shows the URLs of all the open tabs in a textarea so that it can be copied easily. It is my first firefox add-on.

Unfortunately, there is a problem with the mozilla add-ons listing page – I cannot install the extensions using that page. I am getting this error…

Firefox could not install the file at 

https://addons.mozilla.org/en-US/firefox/downloads/file/32487/url_lister-1.1-fx.xpi

because: Invalid file hash (possible download corruption)
-261

However, you can right click the ‘Add to Firefox’ button and choose ‘Save Target As’ and download the file without any issues. Then you can install the extension by dragging the downloaded file into a firefox window. That works perfectly – but not the direct install method.

As a linux user, I have come to expect the fact that servers will collapse when a new version of a distro is released. But those are big files that are transferred(the linux images will be anywhere between 600 MB to 4 GB). But in case of firefox, a 8 MB file managed to bring top servers to their knees. A testament to the popularity of firefox – although I wish mozilla had more mirrors.

If you cannot wait to get the latest version, get it from their FTP servers – they are functioning normally. But, those downloads will NOT BE COUNTED in the final tally for the world record.

I am one of the geeks behind Alertle. Its a web based RSS Reader. I am responsible for a good amount of the JavaScript areas of this app

Features

Single Page Application

The entire application is contained in a single page – everything is done through Ajax. I will not advice that you make something like this(its a maintenance nightmare) but I can say one thing about it – its Cool. With a capital ‘C’.

Keyboard Shortcuts

I got the idea of creating a Keyboard Shortcut Library for JavaScript when I was working on this feature.

Autoplay

You can view articles as you are viewing a slideshow if you enable this.

Feedpacks

You can bunch a group of feeds together into a feedpack – and see all the posts from such a group together.

Sharing

You can share your feedpacks with other users

Perfect for High Volume Feeds

There is one major feature that sets Alertle appart from other RSS readers – it does not tell you if a post is read or not. Yeah, first you will think its a missing feature – but its not. I have used a lot of feed readers – once you subscribe to a couple of high volume feed – like say, BoingBoing or Slashdot or something, you can say goodbye to your sanity. It creates so many new items that the only way of staying away the mess is to click on the ‘Mark all as read’ button once every four seconds. You know what I mean – I am sure you have unsubscribed from many feeds for this reason.

With alertle, you can subscribe all these high volume feeds. And there is no pressure to view all the posts.

If you are an info junkie, I can guaranty that your will get lost for hours in Alertle.

Problems

IE is not Supported

We are still working on this – and due to deadline constraints, we decided to release Alertle without IE support. So if you are an IE user, I am sorry – but What in the World are you Doing? Ditch that terrible browser and get a real browser right now!

If we can get a few people to switch to firefox before we add support for IE, I will say that Alertle gone beyond and above the call of duty to make the web a better place!

Posts don’t have a Read Flag (pun unintended)

Um., yeah, I know – this is both an advantage and a disadvantage. This will prevent me from using Alertle for all my feeds. For my must-read feeds, I will still be using Google Reader. For the high volume stuff, I will use Alertle.

Getting to Know Alertle

So, what are you waiting for? Head over to Alertle and sign up for an account. Its FREE!

But if you are still unconvinced, here is a demo…

Until next time…

AGPL or Affero General Public License Version is a new License released by FSF. This is aimed at Web Applications.

The GNU GPL allows people to modify the software they receive, and share those modified versions with others, as long as they make source available to the recipients when they do so. However, a user can modify the software and run the modified version on a network server without releasing it. Since use of the server does not imply that people can download a copy of the program, this means the modifications may never be released. Many programmers choose to use the GNU GPL to cultivate community development; if many of the modifications developed by the programs users are never released, this can be discouraging for them. The GNU AGPL addresses their concerns. The FSF recommends that people consider using the GNU AGPL for any software which will commonly be run over a network. (Emphasis mine)

Say I used AGPL for Nexty. You decide that it is a nice program – so you download it and use it. Then you make some changes to the code. So far so good.

Then you decide that you can put the modified version on your web server. The visitors can use the modified version of nexty – that is, you are not ‘distributing’ the software. If I used GPL, you could have gotten away with it – but if I use AGPL, you have to publish the code you modified as well.

The end result is that the end user is in a lot of confusion about what they should do with respect to the license. If they are not lawyers, they will not be able to understand what the license says. I have opted to use the BSD license due to factors like this – BSD license basically gives you the right to do anything with it – except claim that you wrote it.
