On Cyber Monday Eve, Jeff Bezos revealed that Amazon may have intentions to one day deliver many of its goods by unmanned aerial vehicles through a service called Amazon Prime Air as part of an segment for the television show 60 Minutes. This notebook explores ~125k tweets from Twitter’s firehose that were captured shortly after the announcement and teaches you how you can be equipped to capture interesting data within moments of announcements for your own analysis.
A consensus algorithm is: a cluster of servers should record a series of records (“log entries”) in response to requests from clients of the cluster. (It may also take action based on those entries.) It does so in a way that guarantees that the responses seen by clients of the cluster will be consistent EVEN in the face of servers crashing in unpredictable ways (but not loosing data that was synched to disk), and networks introducing unpredictable delays or communication blockages.
It turns out that a “data-only” container is one of those concepts that’s really, really simple…once you get it. Perhaps it’s so simple that those who already understand it don’t even see the need to explain it. (Or, perhaps I’m just a little slow…)
Last week, the UK government announced that it is investing £270 million toward quantum computing research as part of the government’s long-term economic plan. The funds will be divided among five quantum technology centers over the next five years.
Cloud computing provider DigitalOcean is now growing faster than Amazon Web Services. Our December 2013 Web Server Survey showed a month-on-month gain of 6,514 web-facing computers at DigitalOcean; Amazon, meanwhile, grew by an almost as huge 6,269 web-facing computers. Together, the two companies accounted for more than two-thirds of the internet-wide growth in web-facing computers in December.
Telegraphy provides real time events for WSGI Python applications with additional features such as event filtering, subscription persistence and authorization/authentication. It’s initially intended for Django but you can extend it to any WSGI framework.
Physicists reported this week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.
This information is available in most operating systems, but each OS has their own way(s) providing it. SIGAR provides developers with one API to access this information regardless of the underlying platform. The core API is implemented in pure C with bindings currently implemented for Java, Perl, Ruby, Python, Erlang, PHP and C#.
Pay by the hour model - Most cloud hosting companies bill customers by the hour (even if you kill the instance after 15 minutes of use), which is lot better compared to old ways of buying physical dedicated hardware in advance. But, its still not pay for what you use. With a shared resources environment like docker, new hosting companies can emerge that charges only for the CPU cycles and memory actually used by the customers.
With last week’s release of Docker 0.7.1, OpenShift’s road to adopting Docker has had a few minor obstacles removed - clearing the way for Docker support to arrive in the not-too-distant future. You may recall, just a few short months ago, Red Hat announced our intention to leverage Docker in OpenShift, delivering a more flexible model for assembling full application stacks.
For the first time, scientists at IBM Research have demonstrated a complex quantum mechanical phenomenon known as Bose-Einstein condensation (BEC), using a luminescent polymer (plastic) similar to the materials in light emitting displays used in many of today’s smartphones.
For sure a few months of exposure will not make you able to provide work like Raft or Paxos, but the basics can be used in order to try to design practical systems, that can be improved over time.
