Home NAS – Turn your old PC into Network Storage Attached Server

Home NAS – Turn your old PC into Network Storage Attached Server

PC lovers tend to collect a lot of hardware as the years roll by. Instead of leaving it to collect dust, why not repurpose it as a file-slinging server? Several free and open-source operating systems run extremely well on a wide array of older hardware. One in particular, FreeNAS, is extremely stable, easy to set up, and laser-focused on storing and sharing files across your home network. All you need is a working system with a reliable hard drive (or three) and a little time to configure everything.

What is FreeNAS?

FreeNAS is based on FreeBSD, itself born of BSD, a version of Unix developed at the University of California, Berkeley. FreeBSD is a full-fledged server operating system, but FreeNAS has been optimized strictly for file serving and storage. It supports SMB/CIFS (Windows file shares), NFS (Unix file shares) and AFP (Apple File Shares), plus FTP and iSCSI. FreeNAS also works with an array of plug-ins for things like automated network backups, BitTorrent downloading, a Plex Media Server, MiniDLNA and much more. The FreeNAS website has an extensive FAQ and community section  that's definitely worth checking out. Read more at PCWORLD - 

LockedUSB MK2 Charge Only Adapter Aimed To Protect You From Malicious Chargers And USB Hacks

LM Engineering Designs LLC, an Atlanta-based Startup, is introducing a new version of their very successful charge only USB Adapter, LockedUSB MK2.  LockedUSB MK2 Adapter provides peace-of-mind while charging your device at Public Charging Stations or Computer USB Ports. LockedUSB Adapter MK2 allows portable devices to fast-charge at their maximum rated current, while keeping the data lines safe and  completely isolated. To cover production costs, the company is launching its new device on the popular crowdfunding site Kickstarter on November 13th, 2014. Supportus_Kickstarter2014 LockedUSB Adapter MK2 is much smaller than it predecessor, it's only 1.5'' long by 0.7'' wide, making it the smallest USB Charger firewall in the market; while still keeping its internal dedicated controller. LockedUSB Adapter MK2 will fully comply with FCC Part 15 (On the US) & CE (in EU), you will have the peace of mind that the adapter will be thoroughly tested by a certified 3rd Party Certification House. It will not interfere with any of your other devices. It will ship in a fully retail ready package, sealed and protected with a 1 Year Limited Warranty.   Last year, LM Engineering Designs,  successfully ran a campaign that raised more than 200% of its initial funding goal.  They kept their backers well informed during the entire process, and the feedback was positive.   Last year researchers from Georgia Institute of Technology produced fake chargers, they’ve named “Mactans”, that do more than just charge your phone.  They install custom, malicious applications onto iPhones and gain access to all of your personal data. Last month Security Experts said, “There is no quick fix for BadUSB Hack”.  BadUSB, a critical security USB flaw identified earlier this year, can be exploited by hackers using practically any USB device. Recently experts published it’s code online, and the issue is spreading like wildfire.  LockedUSB Charger Firewall was designed specifically to protect you from this alarming development.


LockedUSB MK2 can keep your devices protected.  It allows charging of your devices at the maximum rated current while no data communication is exchanged, this mean that no possible hack can infect your host device (Laptop), and also no information can leave your mobile device. LockedUSB MK2 have no internal firmware, everything is handled by hardware so it is not vulnerable to any programing hacks.   Most smartphone users like to charge their phones at work, or on school computers.  Oftentimes at much slower rates than expected. In most cases, they are exposing their personal information, photos, contacts, emails and messages when the computer tries to sync with the device.   Public charging stations are becoming more and more popular everywhere you go.  Unfortunately, Identity Theft, Government surveillance, “rogue” and unstable chargers, are also on the rise. To combat this problem, LockedUSB MK2 completely isolate the data lines from the charger and keep intruders away from your personal information.   Leonardo Matute, founder and Vice-President of Hardware Development at LM Engineering Designs, said the adapter will bring peace of mind to millions of people that charge their device on the go. “Many people don’t think about their information being compromised by a charger,” Leo said. “LockedUSB will not only secure privacy, but it will also allow the devices to charge at their maximum rated current reducing charging times considerable”   Dave Graham, Supporter and Beta Tester from their original campaign, said “Used it in several airports and it passes charge and blocks data. does the job efficiently. I have it attached to the end of my primary charging cable for my phone. Love it.”


LockedUSB MK2 will be available through a 30-day Kickstarter campaign at Interested backers can receive a LockedUSB Adapter MK2 for as low as $16 USD. People who depend on their phones can rest assured LockedUSB MK2 will keep them safe and provide fast charging.   You can get your hands on the original LockedUSB Adapter for a limited time for just $14.99, head over to Kickstarter campaign

Meet the new, reversible USB, Type-C, it can Support up to 100W of power!!!!

The USB 3.0 Promoter Group has announced that it has finalized its redesign of the USB. Called USB Type-C, the specification -- which was announced last December -- aims to solve several problems with current USB design; possibly the most exciting of which is the eradication of "right way up" with a reversible plug. Like Apple's Lightning connector, it can be plugged into its port either way. The new USB is also designed both to be small enough to fit mobile devices, yet robust enough for laptops and tablets. "Interest in the USB Type-C connector has not only been global, but cross-industry as well," said USB 3.0 Promoter Group chairman Brad Saunders. "Representatives from the PC, mobile, automotive and IoT industries have been knocking down our door anticipating this new standard. This specification is the culmination of an extensive, cooperative effort among industry leaders to standardize the next generation USB connector as a long-lasting, robust solution." LockedUSB Adapter USB Charger Firewall The USB is comparable in size with micro USB 2.0 Type-B connectors, with a port size of 8.4 by 2.6mm, yet will be compatible with SuperSpeed USB at 10Gbps (USB 3.1). It will also support USB Power Delivery up to 100W, with additional support for scalable power charging and future USB performance needs. It won't, of course, be compatible with existing USB plugs and receptacles. While the industry begins the slow transition, USB Type-C ports will coexist with other USB ports on devices, and new-to-existing cables and adapters will be made available so that consumers will be able to use the new connector with their existing tech. usb-3-type-c-final
Enable ART runtime

Get a small performance bump on Android by enabling ART runtime (Work on Galaxy S5)

Google on Wednesday announced an update to the Android operating system at its I/O developer conference in San Francisco. The latest version, code-named Android L, includes a revamped notification system, an updated user interface, smarter unlock features, and a new battery-saving mode. One of the performance improvement promise by Android L is by moving away from the old Dalvik runtime to the newer and faster ART. Google introduced ART in 2013 with the Nexus 5 and Android 4.4 KitKat, which means your device must be running KitKat for this process, I tried this on my Galaxy S5 (AT&T) and it worked like a charm.

First: Enable Developers Options 

Go to Settings> About Phone > and click on build number seven times. This will enable your device's Developer options, which will give you access to more advanced settings

Second: Switch your runtime from Dalvik to ART 

Go to Settings > Developer options >  Select runtime > Switch to ART. (Make sure you have more than 50% battery, the switching process take a lot of processing power, you phone will not only suck about 20% of your current battery but it will get really hot)

After rebooting, your device will begin to optimize your apps for the new runtime. This should take a few minutes, but when complete you will notice a considerable performance boost on most devices.

I should warn you, though, that some (and I mean very few) apps may be incompatible with the ART runtime. If one of the apps you use is unable to open or you are having trouble receiving a software update, simply switch back to Dalvik mode using the same process

Galaxy S5 AT&T Finally rooted “towelroot” – Hoping for CyanogenMod next!

You may know the name George Hotz, also known as Geohot. He gained notoriety for his work in jailbreaking and otherwise hacking the aforementioned devices. Well, he is back with a root for the Galaxy S5 on Verizon and AT&T. 

Using a recently discovered Linux kernel vulnerability, geohot has managed to root the Verizon Samsung Galaxy S 5.

The root exploit itself is built around Linux kernel CVE-2014-3153, which was recently discovered by hacker Pinkie Pie, and it involves an issue in the Futex subsystem that in turn allows for privilege escalation. Although expressly released for the Verizon Galaxy S5, the root exploit will realistically be compatible with practically every device with an unpatched kernel–which at this point should be nearly every device not running a recent nightly build of a custom ROM with a patched kernel. As such, it has also already been tested and found to work with the AT&T Galaxy S5, Nexus 5, Galaxy S4 Active, and AT&T and Verizon variants of the Note 3.

As a site note, this method should work with any Android device with a kernel date before June 3, 2014. Certain HTC and Motorola devices are exempt because of the way they mount the system partition, though. If anything, it might be worth trying on your phone if you've been dying for root and are willing to accept the responsibility for anything that might go wrong.

More AT&T Solar-Charging Stations Coming to NYC

More AT&T Solar-Charging Stations Coming to NYC - Stay Protected while Charging on the go with

This summer, New Yorkers can Instagram as many photos of brunch or beach-ready bodies as they want with the help of AT&T's solar mobile charging stations.

The AT&T Street Charge project is expanding with nearly double the number of stations previously available throughout the five boroughs.

Inspired by 2012's Hurricane Sandy, which left many city residents and network providers without a personal power source, AT&T launched its eco-friendly solution last June. Its aim was to keep local folks connected even on the go.

Featuring a modern design (thanks to studio Pensa) and the latest in solar panel and battery technology (provided by Goal Zero), the stations allow users to charge any handheld device with a Micro USB, USB, 30-pin connector, or Lightning port.

"AT&T Street Charge grew out of a need for a sustainable power source during Superstorm Sandy and took on a life of its own when we deployed more than two dozen solar-powered units around the city last summer," AT&T New York state president Marissa Shorenstein said in a statement.
