Before I can run my application code, the microcontroller needs to be initialized properly. Basically this means configuring the pin muxing and clock gates. As this is usually depending on the board or what is attached to the pins, this is named ‘board configuration’ too.
The first step was to transform the data so that I had a data frame where a row represented a day where a member joined the group. To turn that into a chart we can plug it into ggplot and use the cumsum function to generate a line showing the cumulative total:
Every week here and in our newsletter, we feature a new developer/blogger from the DZone community to catch up and find out what he or she is working on now and what's coming next. This week we're talking to Hebert Coelho De Oliveira, Senior Developer at M4U.
Unit testing is a set of skills, that rarely appears on a resume. When I saw a resume with unit testing on it, it rose up to the top of the interview queue. I understood the person who put it there understand what it means to the business.

If you missed anything on DZone this week, now's your chance to catch up! This week's best include the anatomy of Hibernate dirty checking, the similarities of Swift and Scala, the Agile version of Superman vs. Batman, and more.
OpenStack is an open source cloud and that makes it quite unique in comparison to many of the closed source public clouds generally available today. As with any open source project we have the option to contribute and influence how the OpenStack cloud ultimately shapes out.
There are plans to expand this demo project with various integration scenarios or use cases, but for now we start with just a single story around using a JBoss Fuse camel route to interact with a rules and process project deployed onto JBoss BPM Suite.
Batch processing is execution of series of "jobs" that is suitable for non-interactive, bulk-oriented and long-running tasks.Typical examples are end-of-month bank statement generation, end-of-day jobs such as interest calculation, and ETL (extract-transform-load) in a data warehouse.
In the forthcoming articles we consider traditional and state of the art debuggers, introduce some new methods make debugging easier and describe and efficient process of bug hunting. In this first article we shortly outlined the main methods of traditional debugging, and explain their advantages and disadvantages.
The moral of the story is that real options thinking, systems thinking and many other such concepts present or yet to come may be more appropriate in some cases than Lean/Kanban thinking. Lean/Kanban thinking is useful, but it isn’t all there is.
Monitoring is a big part of DevOps, but what’s the best way to get started? Infrastructure monitoring? Application monitoring? What should you monitor? Where should that data go? How can you turn data into information and monitoring into alerts? What about alert fatigue and humane monitoring?
Let’s start with #1 on the list, the simplest, but one of the most important things that you can do to secure your application: Parameterize Database Queries. One of the most dangerous and most common attacks on online applications is SQL Injection.
