KDE 2.0 Development, Which Is Directly Supported

The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development. -
Using the GNU Debugger (Gdb) a Debugger Is a Very Useful Tool for Finding Bugs in a Program
Using the GNU debugger (gdb) A debugger is a very useful tool for finding bugs in a program. You can interact with a program while it is running, start and stop it whenever, inspect the current values of variables and modify them, etc. If your program runs and crashes, it will produce a ‘core dump’. You can also use a debugger to look at the core dump and give you extra information about where the crash happened and what triggered it. Some debuggers (including recent versions of gdb) can also go backwards through your code: you run your code forwards in time to the point of an error, and then go backwards looking at the values of the key variables until you get to the start of the error. This can be slow but useful sometimes! To use a debugger effectively, you need to get the compiler to put extra ‘symbol’ information into the binary, otherwise all it will contain is machine code level – it is much more useful to have the actual variable names you used. To do this, you use: gfortran –g –O0 mycode.f90 –o mybinary where ‘-g’ is the compiler option to include extra symbols, -O0 is no optimization so the code is compiled exactly as written, and the output binary is called ’mybinary’. If the source files and executable file is in the same directory, then you can run the binary through the debugger by simply doing: gdb ./mybinary This will then put you into an interactive debugging session. Most commands can be shortened (eg ‘b’ instead of ‘break’) and pressing ‘enter’ will repeat the last command. -

Simple Scenario with Jenkins Advanced Jenkins : Plug-ins , APIs & Pipelines Toolchain concept Q/A Digital Transformation – Modernization As stated by a As established enterprises in all industries begin to evolve themselves into the successful Digital Organizations of the future they need to begin with the realization that the road to becoming a Digital Business goes through their IT functions. However, many of these incumbents are saddled with IT that has organizational structures, management models, operational processes, workforces and systems that were built to solve “turn of the century” problems of the past. Many analysts and industry experts have recognized the need for a new model to manage IT in their Businesses and have proposed approaches to understand and manage a hybrid IT environment that includes slower legacy applications and infrastructure in combination with today’s rapidly evolving Digital-first, mobile- first and analytics-enabled applications. http://www.ntti3.com/wp-content/uploads/Agile-IT-v1.3.pdf Digital Transformation requires building an ecosystem • Digital transformation is a strategic approach to IT that treats IT infrastructure and data as a potential product for customers. • Digital transformation requires shifting perspectives and by looking at new ways to use data and data sources and looking at new ways to engage with customers. -
