Knowing what to count and how to communicate it can help you and your team track progress, identify problems, and communicate to those around you.

Many value-creating strategies, products, and processes rely on information systems. Yet enabling access to these vital information resources through the procurement, implementation, and use of proprietary software is often complicated and costly. Proponents of open source software (OSS) claim that robust and yet affordable solutions are available because software engineers and programs around the world are able to contribute to source code that is open for anyone to modify and maintain overtime. This production model has shifted the notion of software as the intellectual property of a vendor, to a resource for all. However, questions remain about the viability of OSS for businesses and non-profits. For example, organizations seeking software-based solutions require the security of knowing that the software will not compromise their larger information infrastructure and hurt their business. Some software vendors now provide stable versions of open source software, which they call “vendor driven open source” that combine the strengths of open source with the security of having a direct contract with a company to provide technical/user support and software documentation. Through an exploratory field study of OSS use within city and state government, the researcher seeks insight into its viability for work operations.

So often we’re solely focused on the performance of our production systems. When disaster strikes, your team needs to know when error conditions begin, where they’re coming from, frequency, and an indication of the last time they occurred. Parsing logs isn’t fast enough, and email can’t keep up or preserve metadata.

The initial implementation of Nextbus used a jQTouch-based web client talking to the Translink API via a server-side proxy written in PHP. I eventually added basic stop search history support using localStorage, and recently have re-factored the app significantly: * a less webkit-centric interface * completely new workflow based around Geolocation instead of stop number lookup

MongoDB is a popular new document-based non-relational database. Like all new technologies learning its strengths and weaknesses while trying to support a quickly growing dataset is trying.

Our production environment used an established, well-known Hybrid Cloud hosting company who offered the best IO bang for the buck., including all the bells and whistles: Web-based interface, Ubuntu support, good support and better performance than their competitors. The gotcha was that their massive lead in IO performance was due to their use of SAN storage mounted to each vm via iSCSI. As it turns out, once in a while this storage link would 'hiccup' every once in a while. The effect on MySQL was catastrophic, IOWAIT would go through the roof, and although the box was still up, it was dead as a doornail in terms of workload. It took us a day or tow to figure out what was happening, and then to also figure out that this was happening on the MongoDb replicas as well.

A lighthearted look at how technology can help you get your drink on, and why this actually matters

The pervasive utilization of the social and mobile web has dramatically shaped users’ expectations for where and how they access and share information. The explosive growth of social platforms is now pressuring IT departments to develop enterprise applications that function like Facebook and Twitter. Salesforce has already released Chatter, a “Facebook for the enterprise,” in which information is easily shared and proactively fed to users via a real-time news stream. As enterprises continue to incorporate Cloud-based collaboration, it will be critical to understand the influence of regulatory compliance, which ensures that all appropriate legal reporting and regulatory transparency demands are met. Unfortunately, little legal structure exists that clearly defines and regulates the liabilities and responsibilities of Cloud users. In the face of legislation such as Sarbanes-Oxley, the Health Insurance Portability and Accountability Act (HIPAA), and the Electronic Communications Privacy Act (ECPA), the potential for the myriad data privacy and security issues will undoubtedly grow.

Your brain is really good at surviving in neolithic Africa, but not because of our powers of higher levels of thought; they're much too slow. Humans are so successful as a species because we're champions at automating things, including our own thoughts and behaviours. What's fascinating is that we're profoundly unaware of just how much our own lives run on automatic, and just how much our own behaviour is influenced by external factors. Join internationally acclaimed speaker Paul Fenwick as we examine the fascinating world of the human mind.

The browser doesn't really allow JavaScript to access anything outside its sandbox, but by understanding how the browser works, and making a few approximations, there's a lot that we can measure using just JavaScript.

Optimize your productivity by keeping your body healthy. Learn how to prevent 'laptop back' and RSI; extend your workday by taking care of your body.

Lots of attention has been given to GPUs for speeding up certain types of computations. While GPUs are very well suited for vector operations, there are other things they are not so well suited for. FPGAs (Field Programmable Gate Arrays) are not used as widely yet, but they offer a much more flexible computing fabric than GPUs. You can implement a GPU in an FPGA, for example, or you could implement your own custom processor optimized for very specialized tasks. The barrier to entry can be high for FPGAs: how does a person with a software development background get started using them? And what about HDLs (Hardware Description Langauges) used to program FPGAs? What's the difference between simulation and synthesis? What kinds of tools are freely available? These are some of the questions that will be addressed in this session.
