As referenced in my previous post I’m a pretty big fan of TTYtter.  I won’t go into it’s advantages here you can find that information in my previous post.  I follow quite a few people so one of the first things I did when I started using TTYtter was to write a group add on library for it.  The previous post and the TTYtter site have good information on how to enable these libraries and also how to write them.  This library is pretty good size and performs quite a few operations that I thought would be a good example for someone else looking to extend TTYtter for their own use.

Operations:

1. Custom commands for handling groups
2. Bookmark of tweet id for place tracking what already was evaluated
3. Filtering based on dynamic lists of users
4. Add users to groups from inside TTYtter
5. Remove users from groups inside TTYtter
6. Add users to multiple groups

The easiest way to get started is to install this and get it going.  Download the library from svn and modify the one configuration item at the top of the library to set the group file storage path.  Reference the library from your .ttytterc file or use the library command line switch.

Once loaded you might want to have a look at the command set supported out of the library, there is built in help accessible from within TTYtter

/grouphelp
Group commands are as follows.

/group [groupname]
display stored tweets from group

/groups
list the current groups on the filesystem

/grouplist [groupname]
list the members of group [groupname]

/groupadd [groupname] [username]
add [username] to group [groupname]

/groupdel [groupname] [username]
delete [username] from group [groupname]

At this point you can add some users to a group via something like the following command which adds myself to a group called coders.

TTYtter> /groupadd coders vkoser
User vkoser added to group coders
TTYtter>

Once you have some groups built up it’s really easy to view them in TTYtter by using the /group coders command to list the last 20 tweets from that group.  That’s reasonable if your activly using TTYtter but it’s much more useful to use something like GNU Screen to view multiple groups and assign one screen section per group.  I typically set mine up with split windows and a large scrollback buffer configuration which lets me scroll back through pages of information.

I hope someone can get some value out of this as a learning tool and possibly expand it for your own use.  It’s not overly error proof as an add on for my own use but it works pretty well.  If anyone would like to submit changes or enhancements to the library just send them over to me or contact me on twitter and I’ll see about getting them migrated into the library.

The current release can be gotten here [TTYtterGroups.pl] from the svn repository.

One of my favorite twitter apps is @TTYtter and you can download it from floodgap.com.  It’s written by Cameron Kaiser aka @doctorlinguist on twitter.  Now before we get all crazy and discount TTYtter because it’s not a fancy graphical application with sliding panels and lots of things you can click you need to understand why this is a great tool.

• Scriptable (make your own search/harvesting tool)
• Schedulable (run it, grab search output dump to a file etc…)
• Automate posting information (use it to tweet your coffee pot status etc…)
• Extensible
• Open Source
• Easily runs on almost all varieties of Unix

There are many other features but if your prone to requiring a mouse to interact with a computer this might not be a good fit for you.  It’s the idea of extensibility that I’m going to discuss in this post.  TTYtter has a really nice way to extend it’s functionality or override it’s default behaviors.  One of the things I like most is the ability to just change how it behaves.  If your using an open source client you could just modify the source but then your stuck with what to do when there is an upgrade you have to integrate your changes into the new version if they weren’t something that was accepted back into the project distribution.  TTYtter uses a user defined library that is loaded from your own file.  You can specify a library at runtime that will be loaded with TTYtter that gives a user the opportunity through the use of a little perl to extend or alter the default behaviors.  The big win for this architecture is if a new version of TTYtter comes out it still just loads your custom user library and you get all your customizations with the new version.

I’ve recently fallen back in love with iChat on the mac after finding a nice plug-in that allowed a unified contacts list and I’ve grown used to the time stamp format.  I wanted to add this time stamp format into TTYtter.  There is a default provided time stamp option on TTYtter but it places the time stamp on each tweet which really adds to the width of the displayed line.  I had the idea to create a time stamp that inserted itself every 5 minutes or so that would give me an indication of 5 minute blocks of tweets and also let me find my place if I’m away from my desktop for a meeting or something so I can scroll back to unread items.

You can see in the above screen shot there are two displayed timestamps in the form of “–Mon Jun..”.  The small library I’m going to discuss here inserts those time stamps into the listing of tweets.  This probably isn’t the most elegant way to handle this but it does give you a preview of the type of alterations you can do to TTYtter with your own libraries.

Lets take a look at the code:

$handle = sub {

my $delayInSeconds = 60 * 5;

#load the Lib_past with current time on first run
if(!$Lib_firstrun){
     $Lib_firstrun = true;
     print "Seeding timestamp generator\n";
     $Lib_past = time;
}

#if we have elapsed $delayInSeconds then print a time stamp
if($Lib_past < (time - ($delayInSeconds))){
     $Lib_past = time;
     print "--" . localtime time . "\n\n";
     print "\n";
}

#this allows TTYtter to handle displaying the tweet normally
my $ref = shift;
&defaulthandle($ref);

return 1;

};

The above code is fairly self explanitory but lets take a look at whats happening.  You want to save this code into a file, ichat.pl for instance might be a nice logical choice.  Then when launching TTYtter you need to specify -lib=ichat.pl and this will load your library along with TTYtter.  The above code will be called every time a tweet is received allowing you to customize and extend what happens at that time during code execution.  The last two lines of code are of interest because those two lines allow TTYtter to handle the tweet display as it normally would.  If you want to modify how the tweet is displayed you have full access to do so and override the default behavior.  This is useful for modifying how details are shown, for instance you could add the source client information if you like.  For this library we just want to display our custom time stamp so we’ll let TTYtter handle the tweet display.

You can read all about this advanced use of TTYtter at the website where it is documented.  I encourage you to play around with it it really is quite fun to get things working just the way you like.  I have a much more complicated library that allows me to group users and filter those users tweets into files.  It also allows for group management within TTYtter via custom /commands.  I’ll post details on that in the coming days and add it to the software download page.

I have seen tons of malcontent floating around the internet about the lack of any upgrade pricing for current iPhone 3G users to get an iPhone 3GS without paying non subsidized pricing. This seems ok to me as I understand how the pricing works and It’s been the same for every phone I’ve owned. If I sign up for a 2 year agreement I don’t expect to get a “deal” on another phone until I reach the end of that contract period.  I can tell you from first hand experience though it’s hard waiting when that OMGAWESOME phone you have been waiting on finally comes out and your a year away from an upgrade price.

A friend @thejesse brought up a very valid point today that came across my shared greader items as a comment that I had never considered. If your getting a deal on a phone for a 2 year contract why isn’t your monthly fee lower if you pay up front full price for the phone instead of getting a subsidized phone?  I mean if I pay $800 up front for a phone and the carrier isn’t subsidizing me for a 2 year contract then it only seems fair to get a lower monthly fee since I’m not paying off my phone over the course of the contract.

That being said I do like the looks of the 3GS and my wife will probably upgrade in September when she is able but I’ll probably skip this round due to cost and lack of being able to take advantage of contract pricing.

On a somewhat related note I am rather annoyed at AT&T over not having MMS and tethering ready at os 3.0 launch though.  AT&T has tons of phones already doing MMS and many other carriers will be ready at launch time.  Don’t even get me started on the slingbox working over 3g on windows mobile and blackberry but not iPhone.  It’s inexcusable to not have this ready to go when the 3.0 software launches.  I hope Apple will allow some other carriers in the future in the US to force AT&T to get their act together a bit more.

I work for NCR as my day job.  My division which is an exciting technical mashup of Linux servers using postgresql / apache / php and a large central host technology built around Microsoft technologies like .NET and MSSQL server is hiring.

We just opened 5 jobs and I thought I’d post about them here and try to get the word out.  We are looking for some quality people that have a strong drive to contribute to our product.  While we are part of a large company our solution is somewhat sequestered and feels much more like a startup.  We are in direct contact with our clients, our schedules are aggressive and we get to make our own decisions on our methodologies and architecture.  We are located in the Purdue research park in West Lafayette, IN.  The research park is located just a few miles from campus where there is plenty of entertainment and some decent restaurants.

We normally have one staff meeting a week and then some breakout meetings so typically you’ll have time to focus on development, documentation or testing depending on your job area.  There is a really nice gym across the street that several of us belong to and go to over lunch or before work.  Our solution involves providing a management system for large retailers to create and distribute promotions to customers.  We have a web based tool to create the content and then it’s distributed to the appropriate channels.  There is an official page about us here but it’s not very detailed.
