Create a database from a large CSV file In this example, I will use a CSV file, available on France government opendata web site, containing information about all the French Gas Stations GasStationsDatabase. As Convertigo provides a step to read CSV files, it is very easy to create a project that reads a CSV file, and then write each record into a database. The weak point of this method is the speed. Indeed, writing into a database takes a while and dealing with large CSV files could take “for ever”. I will show you in this article how to create an 11000 records database out of the corresponding CSV file with minimizing the bottleneck of writing. Creating a Microservice? Answer these 10 Questions First This post was originally published on the Datawire blog. Microservices appear simple to build on the surface, but there’s more to creating them than just launching some code running in containers and making HTTP requests between them. Here are 10 important questions that you should answer about any new microservice before development begins on it – and certainly before it gets deployed into production. 1. How will it be tested? Microservices have an interesting set of benefits and drawbacks when it comes to testing.
The_Future_Of_The_Appleseed_Platform 0. Introduction After determining the direction that I feel social networking should follow (in the essay, "The Future Of Social Networking"), I think it's necessary to lay out where I see Appleseed itself going as a software project. Although the project stands incomplete (with very few resources available for further development), I feel as though this project has a certain perspective and approach to social networking that has not been explored by other social networking projects, whether open source or proprietary. It also acts as a preliminary proof-of-concept for that approach as well. The basic idea of this roadmap is to turn Appleseed into more than just a drop-in social networking solution, but to construct it as a distributed social networking application platform.
Build a Kubernetes cloud with Raspberry Pi Ever wanted to make your very own cloud? Now you can! All it takes is some cheap open source hardware and open source software. For about $200, I was able to set up four Raspberry Pi 2s with the Kubernetes cloud operating system using Fabric8. A Reference Architecture for the Internet of Things This is the first article of a two article series in which we try to work from the abstract level of IoT reference architectures towards the concrete architecture and implementation for selected use cases. This first article will cover the definition of a more concrete and comprehensible architecture whereas the second part will then apply this architecture to actual use cases. We are at the edge of a new interconnected world. Under the name “Internet of Things” (IoT) or “Industry 4.0” companies are developing a new network of intercommunicating objects of our everyday life. The IoT interconnects the Things in order to exchange information to fulfill tasks for the users.
MonoDevelop The latest stable release is Cycle 5 Service Release 1 (126.96.36.199). See the Release Notes. Source code is available on GitHub or as a Tarball. For Mac and Windows, you can download Xamarin Studio which is a bundle of MonoDevelop along with Xamarin iOS/Android plugins and branding. Note that a Xamarin license is only required if you develop iOS/Android projects, all other project types are free without restrictions. Mac OS X What is Docker? What is Docker? Docker is all about making it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code.
AppFog Makes 12 Factor Apps Easier. But What Are 12 Factor Apps? - CenturyLink Cloud Businesses have a mandate to gain a competitive advantage from IT. Invariably, this discussion turns to cloud-native apps. Leaders ponder questions like “How can we create, run, and scale new applications quickly and easily?” “How do we experiment, get to market faster, and reduce the cost of trying new things?” GNU Linux-libre project Download | News | How | SVN | Other downloads | Artwork Linux, the kernel developed and distributed by Linus Torvalds et al, contains non-Free Software, i.e., software that does not respect your essential freedoms, and it induces you to install additional non-Free Software that it doesn't contain. GNU Linux-libre is a project to maintain and publish 100% Free distributions of Linux, suitable for use in Free System Distributions, removing software that is included without source code, with obfuscated or obscured source code, under non-Free Software licenses, that do not permit you to change the software so that it does what you wish, and that induces or requires you to install additional pieces of non-Free Software. Our releases can be easily adopted by 100% Free GNU/Linux distros, as well as by their users, by distros that want to enable their users to choose freedom, and by users of those that don't.
What is Kubernetes? Container technologies like Docker are allowing for a new approach to the way developers write and deploy applications. With containers, a developer can easily package up an application with all of the parts it needs, including libraries and other dependencies, and ship it all out as one package, but without the overhead of a traditional virtual machine. But containers themselves, and the developer toolchain which make them easy to use, aren’t the full story. In order to build complex applications requiring different components spanning multiple containers on multiple machines, you need tools to manage and orchestrate your containers. One tool which is helping to solve the orchestration needs of containerized applications is Kubernetes. What is Kubernetes?
Synology RT1900ac review - Page 2 View full gallery The best thing about SRM is Package Center, which is basically an app store. Using Package Center and an external hard drive or SD card, you can add applications to the router, increasing the its functionality and features. Making the Netflix API More Resilient by Ben Schmaus The API brokers catalog and subscriber metadata between internal services and Netflix applications on hundreds of device types. If any of these internal services fail there is a risk that the failure could propagate to the API and break the user experience for members. To provide the best possible streaming experience for our members, it is critical for us to keep the API online and serving traffic at all times. Maintaining high availability and resiliency for a system that handles a billion requests a day is one of the goals of the API team, and we have made great progress toward achieving this goal over the last few months. Principles of Resiliency
Linux Standard Base The Linux Standard Base (LSB) is a joint project by several Linux distributions under the organizational structure of the Linux Foundation to standardize the software system structure, including the filesystem hierarchy used in the GNU/Linux operating system. The LSB is based on the POSIX specification, the Single UNIX Specification, and several other open standards, but extends them in certain areas. According to the LSB:
