On demand data in Python, Part 3: Coroutines and asyncio
Much of the data in modern big data applications comes from the web or databases. You need to write code to process this at scale, but you don't want everything to grind to a halt in the process. Python 3 introduced a system for cooperative multitasking, which alleviates this problem, using asynchronous coroutines. Asynchronous coroutines build on similar concepts to generators. They are objects created from special functions which can be suspended and resumed. They make it possible to break down complex and inefficient processing into simple tasks that cooperate to maximize trade-offs between CPU and input/output. Learn these core techniques following a simple sequence of examples.

On demand data in Python, Part 2: The magic of itertools
Python's motto has always been "Batteries included," to highlight its extensive standard library. There are many well-kept secrets among the standard modules, including itertools, which is less well known in part because iterators and generators are less well known. This is a shame because the routines in itertools and related modules such as functools and operators can save developers many hours in developing big data operators. Learn by copious examples how to use itertools to address the most common MapReduce-style data science tasks.

On demand data in Python, Part 1: Python iterators and generators
The oldest known way to process data in Python is building up data in lists, dictionaries and other such data structures. Though such techniques work well in many cases, they cause major problems when dealing with large quantities of data. It's easy to find that your code is running painfully slowly or running out of memory. Generators and iterators help address this problem. These techniques have been around in Python for a while but are not well understood. Used properly, they can bring big data tasks down to size so that they don't require a huge hardware investment to complete.

Learn how to bootstrap Hydra
The basic idea of OAuth 2.0 and OpenID is when a user wants to do something with an application ("Application X"). Access to the application requires access to an account of a company or business ("Service Z") that would require authorization on the user's behalf. To allow authorization in a good and secure way (without violating the users' trust to ask for the their credentials directly), you can integrate something like Hydra into Service Z so that Application X can make authorized requests on the users' behalf.

Monitor network bandwidth usage and analyze network traffic in the IBM AIX server using ProbeVue
This article helps users to monitor network bandwidth and analyze network traffic in an IBM AIX server using ProbeVue. This provides users with a near real time view of what is happening in their network for a user-specified time interval or when a user specified event occurs. This takes very less time to diagnose certain network issues compared to traditional tools such as IPTRACE and TCPDUMP. This is because ProbeVue provides only the data requested by the user instead of providing the entire data, which requires a lot of time to analyze and diagnose a specific problem.

Validating CSRF vulnerabilities reported by automated scanners
This tutorial covers how to manually validate cross-site request forgery (CSRF) vulnerabilities that can be reported by an automated security scanner, such as IBM AppScan. Most automated scanners, including IBM AppScan, do not accurately report CSRF vulnerabilities, as they are built on predefined rules and cannot completely determine the legitimacy of certain types of vulnerabilities like CSRF. To validate such issues, one needs to manually reproduce the vulnerability and decide whether it is indeed true or a false alarm. This tutorial is a step-by-step guide to reproduce and validate the reported CSRF vulnerabilities by using a custom-made flow chart and also provides guidance on using the open source tool "CSRF Tester" that provides a rich functionality to validate such vulnerabilities.

Think your apps are secure in the cloud?
The cloud is not secure. Developers know through experience that software and servers get hacked thanks to bad code and insecure Internet connections to remote servers and data centers. You can compare using the cloud to having valuables that are locked up in a suitcase in a parking lot. By nature, both are susceptible to attacks. In this article, we explain the reasons why the cloud is not secure, but we also examine ways to mitigate any insecurities by illustrating some Django examples through the inception of BugHeist.
