OLINUXINO is Open Source software and Open Source Hardware, low cost starting from EUR 24 Linux Industrial grade single board computer with GPIOs capable to operate -25+85C.
People keep comparing OLINUXINO with Raspberry Pi and BeagleBone project, so we would like to state the differences here:
New WiFi protocol boosts congested wireless network throughput by 700%
To solve this problem, NC State University has devised a scheme called WiFox. In essence, WiFox is some software that runs on a WiFi access point (i.e. it’s part of the firmware) and keeps track of the congestion level. If WiFox detects a backlog of data due to congestion, it kicks in and enables high-priority mode. In this mode, the access point gains complete control of the wireless network channel, allowing it to clear its backlog of data. Then, with the backlog clear, the network returns to normal.

Big Switch Girds for SDN Battle
As expected, the company is promoting a network architecture that uses OpenFlow to program Ethernet switches. As has been fashionable in SDN circles lately, Big Switch is also espousing the idea of a hybrid network — one where OpenFlow-enabled gear is installed next to traditional routers and switches.

Service providers would prefer to see the northbound and southbound interfaces be open, Griliches says. That’s because a groundswell of applications is expected to emerge now that SDN has become a hot and venture-fundable area, and no carrier wants to suddenly find out its applications don’t work on a particular vendor’s gear.
Africa’s Wireless Gold Rush
It’s no surprise to find multiple network expansion investments, given the rate of mobile growth in the region: According to a new report issued by the GSM Association (GSMA) , sub-Saharan Africa is “the fastest-growing mobile market in the world,” with an average annual growth rate of 44 percent since 2000. The region now has 475 million mobile connections, compared with 12.3 million fixed lines.

Mark Cuban: Facebook Is Driving Away Brands – Starting With Mine
“We are moving far more aggressively into Twitter and reducing any and all emphasis on Facebook,” Cuban says, via email. “We won’t abandon Facebook, we will still use it, but our priority is to add followers that our brands can reach on non-Facebook platforms first.”

“The big negative for Facebook is that we will no longer push for likes or subscribers because we can’t reach them all. Why would we invest in extending our Facebook audience size if we have to pay to reach them? That’s crazy.

Finding Rootkits By Monitoring For ‘Black Sheep’
Blacksheep compares memory dumps from each monitored system, first creating lists of kernel memory modules that are then sorted and compared, calculating the distance that each list of modules is from the others. The system then compares each byte of a modules’ code with other systems to find differences that could indicate changes inserted by a rootkit. Blacksheep also conduct memory crawling to catch changes to kernel data and checks five different kernel entry points for signs of changes.

Vint Cerf and NASA’s BP and DTN Protocol: How It Works
The big difference between BP and IP is that, while IP assumes a more or less smooth pathway for packets going from start to end point, BP allows for disconnections, glitches and other problems you see commonly in deep space, Younes said. Basically, a BP network — the one that will the Interplanetary Internet possible — moves data packets in bursts from node to node, so that it can check when the next node is available or up.

Toshiba laptop service manuals and the sorry state of copyright law
As you would be no doubt already aware, I run a section of my blog here devoted to the free sharing of laptop service manuals. This is a side project I have run for the last three years, gathering as many repair manuals as I could find on the internet and rehosting them on my website for anybody to download and use.
I have unhappy news for you all. Since I was first contacted by Toshiba Australia’s legal department, I have been attempting to discuss with them the potential for me to continue to share their laptop service manuals on my site. Their flat and final response was “You do not have permission [to disseminate Toshiba copyright material] nor will it be granted to you in the foreseeable future.” As a result, all Toshiba material that was on my website is now gone, permanently.

Building a wisp
This guide shows the basic requirements and steps to build a WISP (Wireless Internet Service Provider) using Ubiquiti AirMax devices; suggested equipments and examples are intended for a system of up to 400 subscribers based on a single Base Station and “centrally managed” from the principal router. It covers the following themes: basic legal and commercial requirements, required equipments and basic services on the Base Station, clients’ configuration and general recommendations for starters.
