you select a cloud solution, you need to ensure that the service runs on a dedicated Linux server. Most public cloud Services, such as Amazon Web Services (AWS), Azure, and RackSpace, provide Linux server solutions. If this type of solution is used, you can avoid a lot of technical difficulties during server setup. For example, Amazon provides Amazon device images (AMI) for all the Linux distributions mentioned above in Amazon Elastic Cloud (AE2 ), t

cross-platform development. The logical part is naturally needless to say, the key is how to use the platform features. Nativescript is to get all the platform APIs by reflection, precompile them, then inject these APIs into the JavaScript runtime, then intercept the call after the JavaScript call and run the native code. Nativescript is the use of a lot of web development techniques for app development, as the toolchain and language are very familiar and are popular with many front-end develop

AboutSource codeOnly the XMPP server is used to implement openfire and swift. Think about the stagnation of swift learning during this period, and feel that "if you want to learn the principle of something, you must first use it ", this will increase the understanding of the function processing process to a certain extent and resonate with the source code reading. For Swift API learning, because you have not found any reference system, there is no link on the official document homepage, theref

Background and overviewSwift was originally a highly available distributed object Storage service developed by Rackspace, and in 2010 contributed to the OpenStack open source community as one of its initial core sub-projects, providing virtual machine image storage services for its Nova subproject. Swift is built on a less expensive standard hardware storage infrastructure, eliminating the need for RAID (redundant array of disks), enabling high availa

, tracking, reporting, and so on. Patching systems are similar to fire extinguishing, where users should isolate worms or viruses on the network segment before initiating the patching process. Rackspace's CTO, Mr. Engates, believes that patching routers and firewalls are very similar to the version of the upgrade software. The company is staffed by a network engineer to track vulnerabilities in firewalls and routers. After a patch is identified, the engineer notifies the IT director that if the
