Writing code intended to fail… improves performance? In this non-intuitive paradigm, chaotic fault injection forces developers to write more robust code. This results in a product that is more resistant to small faults and ultimately better performing.

Here is a good discussion of the various factors that affect page speed. From perception of speed to importance of outliers, this discussion touches on the top aspects of page speed as well as improvements.

Owning a Ruby on Rails blog site hosted on Heroku that was performing adequately was no reason to not improve performance! Alex Browne set to see how fast he could get on a tight budget. In all tests and metrics the new static site running on Jekyll on Octopress is much faster and capable than the old version. For only pennies a month, this is a consideration for anyone with a blog that is starting to cost too much.

This technical article explores TCP congestion operation and settings, ultimately creating a case for upgrading the linux kernel. Updates in the 2.6.38.x kernel and more in 3.2.x provide enhanced and additional algorithms to tune congestion-affecting settings. There is no one best fit solution, and an approach of monitoring and adjusting is advised.

Performance on a datacentre’s TCP network can sometimes be significantly worse than expected. TCP Throughput Collapse, also known as TCP Incast, affects many-to-one TCP links resulting in severe underutilisation of capacity. This is seen particularly in clusters where simultaneous requests are made of many nodes. While this article has a focus on erlang, anyone dealing with similar situations will be interested, particularly cluster storage, web search and MapReduce operations.

Conventional wisdom is that scaling out to a cluster is the way to grow into larger data. This paper by Microsoft researchers demonstrate that with realistic, sub-petabyte, operations it is in fact better to scale up to a larger server. Included are recommendations for Hadoop tuning for scaling up as it is designed to work for scale out. Their results imply that future software infrastructures need to be designed both for good scale up and scale out.

By applying performance improvement tools used on external facing websites and products to intranet sites used internally, teams can become more productive and have a better experience at work. When thinking of customer satisfaction, don’t forget about employee satisfaction. The same rules and tools apply. “By creating a culture of data collecting and sharing, you will be able to better examine the data flows inside your organization, and find the cause of many unexpected problems.”Share Now:

The Open Compute Project is a collective effort by Facebook and a number of players in the datacenter industry to bring lessons learned from the social media giant's giant IT deployment to the rest of the world. Datacenters account for 3% of global electricity consumption – about the same as all of Switzerland or the Czech Republic -- according to people I met at the recent Open Compute Summit in San Jose. With increasing mobility at the edge of the cloud and vast new dataflows being predicted with the growth of the Internet of Things (and The Coming Age of Many Zettabytes) in the near...

Wearable technology was dominant at this year’s International Consumer Electronics Show (CES) , and MWC was no exception to this trend. New versions of favorites, such as the Samsung Gear (three new products were released: the Gear 2, the Gear 2 Neo and the Gear Fit), shared the limelight with new wearables like Pebble Time Steel (the new premium version of the company’s previously released smartwatch) and the LG Watch Urbane. The most dramatic difference at MWC was an emphasis on presenting wearables as fashion accessories and moving away from the original clunky technology associated with t...

The list of ‘new paradigm’ technologies that now surrounds us appears to be at an all time high. From cloud computing and Big Data analytics to Bring Your Own Device (BYOD) and the Internet of Things (IoT), today we have to deal with what the industry likes to call ‘paradigm shifts’ at every level of IT. This is disruption; of course, we understand that – change is almost always disruptive.

WebRTC is an up-and-coming standard that enables real-time voice and video to be directly embedded into browsers making the browser a primary user interface for communications and collaboration. WebRTC runs in a number of browsers today and is currently supported in over a billion installed browsers globally, across a range of platform OS and devices. Today, organizations that choose to deploy WebRTC applications and use a host machine that supports audio through USB or Bluetooth can use Plantronics products to connect and transit or receive the audio associated with the WebRTC session.
