Gotta Love This! The Search for “DeathStar”-like Objects!

Dyson SphereIf the Emperor has one out there, we aim to find it! Or, Dyson spheres, or ringed systems, whatever!

Hunting for Alien Megastructures

“It’s a big galaxy out there. Even the most skeptical scientist has to accept that if a civilisation like our own exists, then there’s a good chance we’re not the only one to have ever done so. When most people think about SETI (the search for extraterrestrial intellgence), they imagine someone like Ellie Arroway searching the skies for radio transmissions. But what about looking in other ways? Perhaps a highly advanced alien civilisation might build structures large enough for us to see.
Vast structures, constructed on astronomical scales by advanced civilisations, is what the field of astroengineering is all about. This, admittedly, sounds audacious – and for the human race right now, it is. For us, astroengineering is still very much the realm of thought experiments, theoretical calculations, and science fiction. So it may be surprising to know that certain astronomers have made some quite serious attempts to look for astroengineered artifacts around other stars. With telescopes becoming ever more sensitive, and images being taken of exoplanets, the idea is starting to captivate imaginations once more.

“In 1960, Freeman Dyson published a paper entitled Search for Artificial Stellar Sources of Infrared Radiation. His suggestion was that any megastructure constructed around a star should show itself by emitting more infrared light than it should. The solution was, simply, to look for any sources of infrared which appeared artificial.

Dyson put forward the ideas that any potentially advanced civilisation may need a tremendous amount of power to sustain itself. A method he proposed was to build a vast array of satellites which would enclose an entire star to harvest its energy – a concept which later came to be known as a Dyson sphere. While the concept wasn’t taken too seriously by Dyson himself, it was a powerful enough notion that it garnered a lot of attention.

Unfortunately, it isn’t as simple as looking for infrared light. Many stars, our own included, are surrounded by a disk of dust, and that dust emits plenty of infrared. To find a Dyson sphere, you need to look for a specific signature of infrared light, emitted at just the right set of wavelengths.
And that’s just what an ongoing project, headed by Dick Carrigan at Fermilab, has been doing. Astronomers regularly survey the sky to see what they might find, and Carrigan has been hunting through infrared data to search for Dyson spheres. To date, the project has a handful of candidates, but nothing definitive. Not yet.

But infrared isn’t the only way to spot Dyson spheres. In 2012 Geoff Marcy, an exoplanet researcher, was given a grant to hunt for evidence of Dyson spheres in data recorded by Kepler. In principle, any large artificial objects in orbit around other stars should be detectable in exactly the same way exoplanets are.”

Google to Deliver WiFi to Developing Countries via Blimps!

Google has a plan to get WiFi to developing countries, and it involves satellites, blimps, and ubiquitous WiFi! Can WE be a developing country too? Sigh.

Report: Google developing fund for wireless networks in emerging markets

“Google has already demonstrated its interest in making high-speed Internet across the United States with through the Fiber project, but it looks like the tech giant has a global plan too.

The Wall Street Journal reported on Friday that the Mountain View, Calif.-based company is working on a monetary fund to build wireless networks in emerging markets.

Google hasn’t commented publicly on the report or the fund yet.

But according to the WSJ story, based on unnamed sources, these are the main points to know.

The fund is expected to fuel wireless infrastructures primarily in rural areas where wired Internet connections aren’t available, especially in Southeast Asia and Sub-Saharan Africa.

It still remains to be seen how Google plans to go about this project, either by building the networks itself or partnering with local wireless companies — or some balance of both, depending on the market.

Such an initiative does fall in line with some of Google’s more philanthropic schemes and rhetoric, much of which CEO Larry Page reiterated at Google I/O in San Francisco last week.

But getting more people online and enabling them with wireless connectivity also has possibility to boost the mobile user base in these regions, outfitting them as prime consumers for low-cost Android smartphones, featurephones, and even tablets.”

Geek Software of the Week: Zentyal!

Zentyal LogoDon’t spend your hard earned money on the Evil Empire (Microsoft’s) Small Business Server! Get all those capabilities and more for FREE! This was recommended by one of our faithful viewers that just installed it, and loves it!

Zentyal – Linux-based FREE Small Business Server!

“Zentyal is a Linux small business server that can be configured as a Gateway, Unified Threat Manager, Office Server, Infrastructure Manager, Unified Communications Server or a combination of them. The development of Zentyal started in 2004 and currently it is the open source alternative to Microsoft network infrastructure products aimed at small and medium businesses (Windows Small Business Server, Windows Server, Microsoft Exchange, Microsoft Forefront…)

Highlights:

  • New distribution base: Ubuntu 12.04, providing new versions of all the packages and services managed by Zentyal.
  • Improved performance: there is now a global cache to speed up all the requests to the Redis configuration backend. Also, the MVC framework uses now a new model load system to save some CPU processing and to reduce memory usage.
  • Improved reliability: new locking and transactions systems have been developed to avoid any risk of data incoherences or corruptions.
  • Samba 4 integration: a full replacement of the Windows Server Active Directory, which allows Zentyal to join as additional controller of an existing AD Domain.
  • Kerberos integration: single authentication for HTTP Proxy, Mail and Zarafa groupware, in addition to File Sharing which is already provided by Samba
  • New look & feel for the Web interface along with usability improvements.
  • New Master-Slave architecture: now it’s easier than ever to synchronize your users between several Zentyal servers.
  • New UPS module:it helps to keep your server always up and running in case power outages.
  • New Thin Clients module using the popular LTSP software.
  • Reviewed HTTP Proxy with a simpler interface and improved filtering by time period.
  • Zarafa 7.1: a new version of the groupware suite featuring a new web interface, multi-domain support and web chat integration.
  • Support for advanced NAT rules in Firewall module”

Today is Geek Pride Day!

So, I am ALWAYS proud to be a geek! But, today, we are reminded to indulge in our geekiness!

Wikipedia: “Geek Pride Day (Spanish: Día del orgullo friki ) is an initiative to promote geek culture, celebrated annually on 25 May. The date was chosen as to commemorate the release of the first Star Wars film, A New Hope on 25 May 1977 (see Star Wars Day), but shares the same date as two other similar fan “holidays”: Towel Day, for fans of The Hitchhiker’s Guide to the Galaxy trilogy by Douglas Adams, and the Glorious 25th of May for fans of Terry Pratchett’s Discworld.

The initiative originated in Spain in 2006 as “Día del Orgullo Friki” and spread around the world via the internet.”
