RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data ... has interfaces in all the usual open source scripting languages
Expect is an extension to the Tcl scripting language to create an automation and testing tool for CLI applications such as telnet, ftp, passwd, fsck, rlogin, tip, ssh, et., and because it wraps the standard command-line interface, it can be used to automate any arbitrary applications that are accessed over a terminal.
I can't imagine building a user interface intensive application through this technique. It would be extremely cool if they could integrate Interface Builder,
This Smalltalk company seems to have reified the Cocoa UI toolkit beautifully. Judging by the Ambrai website, there don't seem to be any retail Smalltalk compilers in the pipeline.
However this could be a great lesson in how to reify John McIntosh's new Objective-C bridge for Squeak, or Etoile's Smalltalk library, if it hasn't been done already.
A feature-complete fluent .net library for the Twitter API.
A simple, discoverable, fluent interface for building Twitter queries, as well as additional features like asynchronous processing, server-side caching, url shortening, and rate throttling. Now go, create.
The industry stewards have countered Apple's move with their own application stores, so there's a huge opportunity to write the "killer app" for one of several smartphone platforms.
40 MB to less than 4 MB of free RAM
one-app-at-a-time requirement complicates any implementation of a copy-and-paste mechanism.
As a security sandbox, the iPhone OS permits only one third-party application to run at a time, and not in the background.
adding some useful Bluetooth profiles that supported stereo headsets, data synchronization, or the ability to implement multiplayer games would be usefu
iPhone OS 3, that provides some of the missing features mentioned here, such as the A2DP profile for Bluetooth, voice recording, and copy-and-paste.
Have to learn Objective-C; is only smartphone platform that uses it.
Competitors will soon catch up on the UI.
embed navigation and GPS plotting into applications.
provide their own map content
The OS now supports the use of accessories connected to the iPhone either through its 30-pin docking connector or wirelessly via Bluetooth. Now that the device has been "opened", you can expect an entire ecosystem to build up around the device, much like the iPod has.
peer-to-peer connectivity using Bonjour
developers can now allow users, from within the application, to purchase and obtain new content
No voice dial.
A client-server mechanism provides access to low-level system resources, and in fact the kernel itself is a server that parcels out resources to those applications that need them. This transaction scheme allows applications to exchange data without requiring direct access to the OS space.
C/C++ for porting existing UNIX applications, and Java to port Java ME MIDlets. As mentioned previously, the software stack offers several run-times that offer application development using WRT widgets, Flash, and Python.
The primary programming language for the platform is Symbian C++,
Handango has managed the wide-scale distribution of Nokia applications. In February, Nokia announced plans to launch its Ovi Store, which sells applications, videos, games, pod-casts and other content, similar to Apple's App Store. The store will be accessible by Nokia S60 smartphones in May.
Non-standard Symbian C++ has steep learning curve, with special idioms to master.
Large number of Symbian APIs to learn, since it contains hundreds of classes and thousands of member functions.
Manages multiple e-mail Exchange e-mail accounts, along with support for POP3 and SMTP, and e-mails can have file attachments
FIPS 140-2 compliant, and supports AES or Triple DES encryption sessions via BlackBerry Enterprise Servers
BlackBerry Device Software has enhanced the capabilities of the platform with its own Java virtual machine (JVM), along with new Java classes that offer multitasking capabilities and UI enhancements to go beyond the capabilities of Java ME.
You can also take existing Java ME code and add specific BlackBerry classes to make a hybrid Java ME application
don't intermix MIDP 2.0 and BlackBerry API calls that perform either screen drawing or application management.
The catch to writing an application that uses BlackBerry API extensions is that it ties the application this smartphone. However, this is no worse than using the unique Java classes found in Google's Android.
Apple promotes the design goal that applications should accomplish one purpose.
no Flash support, and you can't download files.
For non-Exchange users, Apple's MobileMe online service, after some fits and starts in 2008, now supports the push of e-mails and changes to the calendar and contacts.
The iPhone 3G can work in tandem with Microsoft Exhange Server 2003 and 2007 to support enterprise operations.
Cocoa Touch is a subset of Apple's Cocoa,
Cocoa Touch components manage most of the writing to the screen and playing media, yet there are APIs exposed that let you access the accelerometer and camera.
Quartz engine is identical to the one found in Mac OS X
Only a select few higher-level frameworks have access to the kernel and drivers. If necessary, an application can indirectly access some of these services through C-based interfaces provided in a LibSystem library.
the SDK provides Dashcode, which is a framework based on a Web page composed of HTML and Javascript. You can use DashCode's simulator to write and test your web application. You can also use several other third-party frameworks to write web applications, and debug these with Aptanna Studio's tools.
Made by HTC, the G1 is the first smartphone using the Android platform.
e-mail program (which makes use of Google's Gmail), a mapping program (using the company's Google Maps), and a browser that uses WebKit, not Google's Chrome web browser
Android is not Java ME, nor does it support such applications
ability to both browse and manage multiple IM conversations. On the other hand, such heavy use of the smartphone's CPU shortens battery life significantly. Maybe Apple is on to something in limiting the number of applications that the platform can run.
On the positive side, the Android APIs support a touch interface (and the G1 has a capacitive touch screen), but not any multi-touch gestures.
copying text from the web pages is the browser isn't allowed
The advantage to Android's use of a different bytecode interpreter is that the DVM was designed so that multiple instances of it can run, each in their own protected memory space, and each executing an application. While this approach offers stability and a robust environment for running multiple applications, it does so at the expense of compatibility with Java ME applications.
Seasoned Java programmers will find the Android SDK an amalgam of Java SE and Java ME methods and classes, along with unique new ones
compile the Java code to generate Dalvik bytecode files, with an extension of .dex. These files, along with the manifest, graphics files, and XML files, are packaged into an .apk file that is similar to a Java JAR file.
The certificate that you use to generate the private key does not require a signing authority, and you can use self-signed certificates for this purpose.
The Developer Phone provides access to a shipping Android device without the cash outlay or contract contortions required when developing for the other platforms.
in February the site began supporting priced applications. Google allows developers to take seventy percent of the proceeds.
it's possible that you might pick up a malicious application before it is detected by the user community.
Open source, open platform: if you hate the mail program, some third-party is writing a better one.
Lengthy developer's overview of Symbian, Mac OS X iPhone, Blackberry, Android. This talks about the leading app platforms except Java ME and Windows Mobile, though it does explain how Blackberry and Symbian support Java ME.

Dasher is an information-efficient text-entry interface, driven by natural continuous pointing gestures without requiring a mouse. Would work great on PDAs...
JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be used as a tool for cleaning up malformed and faulty HTML. In addition, JTidy provides a DOM interface to the document that is being processed, which effectively makes you able to use JTidy as a DOM parser for real-world HTML.
The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java or ECMA 335 virtual machine. It is up to 50 times faster than local RPC via SOAP, requires less resources on the web-server side. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java.
« CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content ― computer programs, HTML markup, and similar. »
Conceptual and task-oriented information. Guides include overviews, tutorials, programming guides, server administration guides, and, for developer tools, user guides.
« Writing efficient user interfaces is the main maxim, here at Vimperator labs. We often follow the Vim way of doing things, but extend its principles when necessary.
Towards this end, we've created the liberator library for Mozilla based applications, to encapsulate as many of these generic principles as possible, and liberate developers from the tedium of reinventing the wheel. »
RMagick is an interface between the Ruby programming language and the ImageMagick® and GraphicsMagick image processing libraries.
RMagick can be more difficult to install than the typical Ruby extension. First you have to install ImageMagick or GraphicsMagick, and those libraries require a lot of other libraries. Nevertheless, the process can be made easier with a bit of planning. On this page I'll try to answer the most common questions about installing RMagick. Give it a quick scan before you start downloading files.
