I am trying to use "MTNL 3G Jadoo" data card (Teracom LW272) with Ubuntu 12.04. On connecting, it gets mounted as a drive containing the client installation .deb file. I opened the .deb file in Ubuntu Software Center and installed it. I searched for "MTNL" in Ubuntu search and found "MTNL 3G Modem" application. But it won't run. I found it is installed in /opt/MTNL-3GModem. I tried running it from the terminal as: sudo /opt/MTNL-3GModem/ModemClient, but no luck.
Any idea how to get it working?
I am executing a simple query/stored procedure from my application against a large table and it's taking a long time to execute. The column I'm using in my WHERE clause is indexed and it's very selective. The search column is not wrapped in a function so that's not the issue. What could be going wrong?

In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser.
The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server.
Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations.
Anyone had similiar experience and wants to share their tricks/suggestion ?
Do I need to tell my boss 'there is no future without a web server'?

The Search Contract feature helps improve the accessibility of your application. When a user is trying to search for something through the charms, you see a bunch of apps that get listed below. You see that Store, Howzzat Book and Live Reader apps have implemented this feature. So a user types in some text and clicks on one of these apps and this text is passed to the app where you can show the results of this search directly. Let’s see how to get this implemented. I have created a Blank App named...(read more)

Hi all.
I have an app that works with a list of objects so has one central keyed list.
The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading.
Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit.
I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way.
I can also do it lazily and repopulate the tree each time or periodically (very hackish).
Does anyone have any better thoughts on how to structure this?
This is being done in C# 2.0 but the concepts apply to any environment.
Thanks
I am building a small social web application. I am developing it with rails. I want some cheap or free image hosting which I can use as my image repository for my website because I can't afford Amazon cloud store or something like that. Can I use flickr, imageshack or service something like that? Do they allow me to store images for my website? Suppose I wanna use pics for blogpost and I will be extracting pics from their api and show on my blog post. Is that possible? Sorry I'm beginner.
I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems.
I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own.
Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out?
Thank you!
*LE: * I want to cache DB information in POJOs just like JPA or Eclipselink
When you launch an instance and explicitly name it using:
juju deploy lamp website1
Is there a way on the newly created instance to get the data that tells the machine that its:
called website1
or even better:
a unit number such as website1/0, website1/1 etc etc
The reason for doing this is that in my charm I wish to set the hostname to this value.
I did wonder if it was set via ec2metadata but it doesn't seem to list this information.
Many of us went through a scenario like, can us pass a full of C# type/class to the javascript?
Modify from there and again return back to C#? The difficulty is that JavaScript only knows string format comared to C# which has many data types. So how we can pass an entires class to JavaScript? Here we need to handle with JSON serialization techniques.

There are numerous databases housing the same information and it's getting quite difficult to keep everything in line. I've heard from a number of departments who want a more centralized approach to handling customer data, but I don't know where to begin. Can you steer me in the right direction?
SQL is a powerful tool for querying data, and for aggregating it. However, you can't easily use it to draw inferences, to make predictions, or to tease out subtle correlations. To provide ever more sophisticated inferences to businesses, the race is on to combine the power of the relational model with advanced statistical packages. Both IBM and PostGres are ready with solutions. And SQL Server? Hmm...
At times I often want to know what is happening inside my SQL Servers, there are of course a multitude of ways I could "peek" into the activity that has been happening, Sometimes I just need to get a quick summary of those facts, maybe just to know if anything unusal has happened I'm not yet aware of, an easy way I can do that is to query the DMV sys.dm_os_performance_counters, As t here are tons of blog posts already out there on using the data from this DMV, I'm not going to focus...(read more)

Question about Byte-Pairing for data compression. If byte pairing converts two byte values to a single byte value, splitting the file in half, then taking a gig file and recusing it 16 times shrinks it to 62,500,000. My question is, is byte-pairing really efficient? Is the creation of a 5,000,000 iteration loop, to be conservative, efficient? I would like some feed back on and some incisive opinions please.
Best Regards.
