C++ Little Wonders: The C++11 auto keyword redux

AddThis Social Bookmark Button
I’ve decided to create a sub-series of my Little Wonders posts to focus on C++.  Just like their C# counterparts, these posts will focus on those features of the C++ language that can help improve code by making it easier to write and maintain.  The index of the C# Little Wonders can be found here. This has been a busy week with a rollout of some new website features here at my work, so I don’t have a big post for this week.  But I wanted to write something up, and since lately I’ve been
renewing my C++ skills in a separate project, it seemed like a good opportunity to start a C++ Little Wonders series.  Most of my development work still tends to focus on C#, but it was great to get back into the saddle and renew my C++ knowledge.  Today I’m going to focus on a new feature in C++11 (formerly known as C++0x, which is a major move forward in the C++ language standard).  While this small keyword can seem so trivial, I feel it is a big step forward in improving readability in C++ programs.

Monitoring and Service Management for Distributed Environments

Event Lobby (EVENT: 403172):



The Consumerization of IT at end points and within data centers is being driven by a raft of technology and market changes - Cloud, virtualization, exploding mobile end points (tablets, smartphones, etc.) and proliferating service providers. These changes are fundamentally shifting the role of IT organizations and CIOs. IT is stepping up to become a driver for positive change in the business – forging and managing relationships
with cloud and other service providers to provide higher levels of service at lower costs for “non-core” services, and using freed resource to deliver key differentiation that drives business growth. 

In this session we’ll briefly cover the key elements of these trends, how they drive new roles within IT, and the changes from traditional Monitoring and Service Management needed to set and keep SLAs within these new, distributed environments.

  Learning Outcomes Discuss the physical characteristics of magnetic disks Describe how data is organized and accessed on a magnetic disk Discuss the parameters that play a role in the performance of magnetic disks Describe different optical memory devices Magnetic Disk The way data is stored on and retried from magnetic disks Data is recorded on and later retrieved form the disk via a conducting coil named the head (in many systems there are two heads)
The writ mechanism exploits the fact that electricity flowing through a coil produces a magnetic field. Electric pulses are sent to the write head, and the resulting magnetic patterns are recorded on the surface below with different patterns for positive and negative currents The physical characteristics of a magnetic disk   Summarize from book   The factors that play a role in the performance of a disk Seek time – the time it takes to position the head at the track Rotational delay / latency – the...(Read whole news on source site)

Available memory and Background agents in Windows Phone 7

AddThis Social Bookmark Button
source: blogs.ugidotnet.org When you create a background agent for Windows Phone 7 there are a couple of important details you must be aware of: The total scheduled time for the agent to execute is 25 seconds, if you exceed it the agent will be killed by the scheduler. The max amount of memory available is 6 MB, if the agent allocates more the agent will be, again, killed. With Visual Studio debugger attached these limits are disabled. An agent is killed silently
and after two killing operations the scheduler will automatically disable it and your user probably will start wondering why your wonderful tile doesn't work as expected. The common problem I face when dealing with agents is that 6 MB of memory are a very strict constraint especially when you realize that the agent alone consumes more than 3 MB (in real cases I got more than 5 MB allocated at startup) . So what can you do do live in a such restrict space? along with optimizations (in some cases I ended up duplicating code in order to avoid...(Read whole news on source site)

Using RAD Studio XE2 Update 4? Make sure you get VCL subscription 11.2.5!

AddThis Social Bookmark Button
A couple of weeks ago we released 11.2.4 of our VCL Subscription and, wouldn’t you know it, the very next day Embarcadero released Update 4 for RAD Studio XE2. Much merriment was heard in the halls of DevExpress Towers, I can tell you… We’ve now completed our tweaks and tuning and we’re happy to announce that we released 11.2.5 this morning. Go download it now! I hope that John Thomas’ promised hotfix for Update 4 doesn’t get released tomorrow, otherwise I might just have to make a visit to Scotts Valley with Mario and Luigi. You can
read what’s changed in this release here. I will also note that although this release will install in XE2 Update 3 or earlier, the evaluation version will require XE2 Update 4 to be installed. I, of course, exhort you to install Update 4 anyway....(Read whole news on source site)
