High school student makes own Google Wave client, Ruby on Sails

A New Jersey high school student took seriously Google’s open protocol of their new Wave product and has begun developing one of the first non-Google Wave-compliant products, called Sails.

Daniel Danopia is still a high school student in Landisville, New Jersey, but with a talented and promising future.

Danopia, as he goes by online, commenced Ruby on Sails – a pun on both Google Wave and his programming language of choice, Ruby – on the 19th October. Within this short timeframe he has already produced a federated Google Wave provider.

During his project, Danopia created a reusable ProtoBuffer class that can be used by any Ruby project needing to parse or encode Google ProtoBuffers and will no doubt be built upon by Wave-related Ruby projects to come.

Additionally, for testing and debugging, Danopia constructed a lightweight telnet server to dump the list of waves to the terminal along with history. As well as being useful for administration in its own right, the code shows how simple it can be to interact with his Sails server.

Danopia is particularly proud of his achievement in implementing Federation. To the best of his knowledge, he has developed the only non-Google-written server with semi-working federation. Federation essentially means two distinct systems can interoperate; in other words, users of different Wave providers can send messages to Sails and vice versa.

Danopia’s project is impressive on two fronts; firstly, it is the work of a high schooler in between homework and classes. Danopia has taken on a project which is topical and current and which may intimidate older and more experienced developers.

Secondly, Danopia’s code is concise. The main Ruby code file is 865 lines including whitespace. The telnet server is 50 lines.

You can inspect Danopia’s implementation and GitHub project via the links on his blog.

Hybrid cloud promises to bring together the best of both worlds enabling businesses to combine the scalability and cost-effectiveness of the cloud with the performance and control that you can get from your on-premise infrastructure.

Reducing WAN latency is one of the biggest issues with hybrid cloud performance. Taking advantage of compression and data deduplication can reduce your network latency.

Research firm, Markets and Markets, predicted that the hybrid cloud market size is expected to grow from US$38.27 billion in 2017 to US$97.64 billion by 2023.

Colocation facilities provide many of the benefits of having your servers in the cloud while still maintaining physical control of your systems.

Cloud adjacency provided by colocation facilities can enable you to leverage their low latency high bandwidth connections to the cloud as well as providing a solid connection back to your on-premises corporate network.

Download this white paper to find out what you need to know about enabling the hybrid cloud in your organisation.
