Make your Ada code live up to the language's elegant name with AdaCore's new CodePeer, a source code analysis tool that detects runtime and logic errors in Ada programs. As a code reviewer, CodePeer identifies constructs that are likely to lead to runtime errors, such as buffer overflows, and flags legal but suspect code typical of logic errors. Additionally, AdaCore says that its tool goes “beyond the capabilities of typical static analysis tools”, producing a detailed analysis of each subprogram, including pre- and postconditions, which allows for early detection of potential bugs and vulnerabilities. CodePeer can be used both during system development or as part of a systematic code review process. Finally, it can be used either as a standalone tool or fully integrated into the GNAT Pro Ada development environment.
First there were seven brides for seven brothers, and now there are seven tech books for seven strains of security geek—all courtesy of Syngress. The publisher is promising a whopping seven books in the Seven Deadliest Attacks Series, each with its own focus on a specific type of security breach. The titles include: Seven Deadliest Microsoft Attacks by Rob Kraus, Brian Barber, Mike Borkin and Naomi Alpern; Seven Deadliest Network Attacks by Stacy Prowell, Rob Kraus and Mike Borkin; Seven Deadliest USB Attacks by Brian Anderson and Barbara Anderson; Seven Deadliest Wireless Technologies Attacks by Brad Haines; Seven Deadliest Social Network Attacks by Carl Timm and Richard Perez; Seven Deadliest Web Application Attacks by Mike Shema; and (almost there) Seven Deadliest Unified Communications Attacks by Dan York. Each book covers the anatomy of the seven respective attacks, as well as how to get rid of and defend against them.
Keep the burglars at bay with SoleraTec's new and improved Phoenix RSM, an overarching forensic video surveillance management system. The RSM part stands for Phoenix's Record, Store and Manage capabilities. Other product capabilities include searches in video surveillance environments; incrementally scalable three-medium (hard disk, digital computer tape and optical) on-line and off-line multitier storage; and unlimited retention and support for an unlimited number of cameras, servers and users. Furthermore, video from all connected cameras can be reviewed, investigated and exported with client tools that run on Windows, Linux and Mac OS. Features added to the new version include one-step centralized camera configuration, simplified camera policy management and support for QuickTime and VLC media players.
Waspmote from Libelium is a modular platform for wireless sensor networks that enables environmental monitoring in adverse conditions and remote locations with its radio range of up to 40km. The sensors are intended for deployment in fire and flood detection and other environmental monitoring applications. Waspmote networks can communicate to the external world via GPRS or in situations with very difficult wireless connectivity, such as mines. Each sensor device can store more than 21 million different sensor measurements in its internal memory. Waspmote's four power modes—on, sleep, deep sleep and hibernation—enable a device to function for up to three years without recharging the battery, while a small solar panel can allow it to run indefinitely. Special boards that enable detection of gases and physical events (such as pressure, impact, vibration, temperature and so on) can be integrated. Open-source API and programming environment are available.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
