Sending SMS from Website using GSM Modem »

There are a couple of times we are asked on how to send SMS from an ASP.NET web application using a GSM modem. Normally in this case the user will try to directly connect to the GSM modem from within the web application and perform the sending.

Normally this will not work as the web application is hosted under a web server, and sometimes this could cause a problem.

Scenario 1 – Web application and GSM modem is in the same machine

Instead you should develop a Windows service that listens to a database table for incoming message. The web application should inserts messages to be sent into an outgoing message table.

The Windows service should regularly check for incoming messages from the modem, and insert those messages into an incoming message table. The web application accesses the table to check for newly arrived messages.

Scenario 2 – Web application and GSM modem are on different machines

If your web application is hosted somewhere else under a web hosting company, the web application will still insert the outgoing messages into a database table. But now you will need to develop a web service to return those newly inserted messages.

On the machine that you have the GSM modem installed, invoke the web service to get the outgoing messages, connect to the modem and send out the messages. You could call another web service to update the status back to the database.

If you are looking for sample source, have a look at SmartGateway which is available at Google Code.

Versatile Log File Parsing with LogParser »

Log parser is a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows® operating system such as the Event Log, the Registry, the file system, and Active Directory®.

You tell Log Parser what information you need and how you want it processed. The results of your query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Most software is designed to accomplish a limited number of specific tasks. Log Parser is different… the number of ways it can be used is limited only by the needs and imagination of the user. The world is your database with Log Parser.

Optimize PNG Image Size »

PNGGauntlet is a .NET program that uses Ken Silverman’s PNGOUT command line utility to optimize PNG files. Many PNG files output by popular graphics software packages like Photoshop or Fireworks are not as small as they could be.

PNGGauntlet squeezes the last bit of size out of them. Furthermore, no information is lost during this process – the only thing that changes is the file size. Just select the files you want to optimize (or drag them onto the window), select where you want them to go, and click the button. PNGauntlet can also be used to convert JPG, GIF, TGA, PCX, and BMP files to PNG.

Glimpse for ASP.NET Website »

Glimpse is an amazing product that allows you to see exactly what’s going on in your web server. Currently, it works for any ASP.NET website and even has specific extensions for specific frameworks like (ASP.NET MVC, etc.).

Besides just supporting frameworks such as these out of the box, Glimpse has an architecture that fundamentally supports the future development of Server side implementations of Glimpse for other non-ASP.NET based system in the future.

Glimpse plugins, either built into Glimpse, or provided by third parties or yourself run on the server and collect all server side information that will aid in debugging (i.e. application settings, routes, session variables, trace data, etc.)

Before the response is send, the Glimpse formats the data collected by the plugins in accordance with the Glimpse Protocol and serializes it as JSON

Depending on whether it is an Ajax request or not, the server embeds the JSON in an HTTP Header or in the content of the page.

JavaScript on the clients picks up the JSON data sent by the server components and displays and dynamically renders a client side UI (similar to Firebug Lite) that lets you view this data.

Glimpse can be turned on or off by a series of different mechanistic, but at its core if the Glimpse cookie is present the server will provide the "debug" data – as a security measure, the request for debug data is "authenticated". Via the plugin model, this authentication check can have any logic that is required by the site to ensure that unauthorized users don’t have access to sensitive debug data.

Javascript Library for HTML5 and CSS4 WebSites »

Modernizr is an open-source JavaScript library that helps you build the next generation of HTML5 and CSS3-powered websites.

Modernizr is a small JavaScript library that detects the availability of native implementations for next-generation web technologies, i.e. features that stem from the HTML5 and CSS3 specifications. Many of these features are already implemented in at least one major browser (most of them in two or more), and what Modernizr does is, very simply, tell you whether the current browser has this feature natively implemented or not.

Unlike with the traditional—but highly unreliable—method of doing “UA sniffing,” which is detecting a browser by its (user-configurable) navigator.userAgent property, Modernizr does actual feature detection to reliably discern what the various browsers can and cannot do. After all, the same rendering engine may not necessarily support the same things, and some users change their userAgent string to get around poorly developed websites that don’t let them through otherwise.

Modernizr aims to bring an end to the UA sniffing practice. Using feature detection is a more reliable mechanic to establish what you can and cannot do in the current browser, and Modernizr makes it convenient for you in a variety of ways:

  1. It tests for over 40 next-generation features, all in a matter of milliseconds
  2. It creates a JavaScript object (named Modernizr) that contains the results of these tests as boolean properties
  3. It adds classes to the html element that explain precisely what features are and are not natively supported
  4. It provides a script loader so you can pull in polyfills to backfill functionality in old browsers

yepnope–Asynchronous Resource Loader »

yepnope is an asynchronous conditional resource loader that’s super-fast, and allows you to load only the scripts that your users need.

  • yepnope.js is only 1.6kb – smaller than most and certainly a good size for its functionality set.
  • yepnope.js is called a "resource loader" because it can work with both JavaScript and CSS.
  • yepnope.js has a full test suite in QUnit that you can run in your set of supported browsers to make sure it works. (We run it via TestSwarm in every browser we can get our hands on)
  • yepnope.js fully decouples preloading from execution. This means that you have ultimate control of when your resource is executedand you can change that order on the fly.
  • The yepnope.js api is friendly and encourages logical grouping of resources.
  • yepnope.js is modular. It has a whole system for adding your own functionality and a couple examples of how you might do that. (Prefixes and filters).
  • The yepnope.js api encourages you to only load the resources that you need. This means that even when it’s slower than another script loader, it still can come out on top, because you could avoid an entire resource.
  • yepnope.js is integrated into Modernizr.
  • yepnope.js always executes things in the order they are listed. This is a pro for some, and a con for others. We think it’s a friendly default.
  • yepnope.js has the capability to do resource fallbacks and still download dependent scripts in parallel with the first.

Mongoose–Easy to use Web Server »

Mongoose is easy to use web server. It also can be used as embedded web server library to provide web interface to applications.

Mongoose executable does not depend on any external library or configuration. If it is copied to any directory and launched from there, it starts to serve that directory on port 8080 (so to access files, go to http://localhost:8080). If some additional config is required – for example, different listening port or IP-based access control, then a mongoose.conf file with respective options can be created in the same directory where executable lives. This makes Mongoose perfect for all sorts of demos, quick tests, file sharing, and Web programming.

Features

  • Crossplatform – works on Windows, MacOS and most flavors of UNIX
  • CGI, SSL, SSI, Digest (MD5) authorization, resumed download, aliases
  • IP-based ACL, Windows service, GET, POST, HEAD, PUT, DELETE methods
  • Small footprint: executable size is 40 kB on Linux 2.6 i386 system
  • Embeddable with simple and clean API. Source is in single .c file to make things easy. Minimalistic embedding example is in hello.c.
  • Python bindings
