Kicking around in technology since 2002. I like to write about technology products and ideas, but at the consumer level understanding. Some tech, but not too techie.
Revi Charger is a creative form factor. The Revi power station is a cordless device which will accommodate either USB or microUSB sockets.

One of the most classic and – yet still perversely prevalent – issues IT staff face is resetting Windows passwords for users who have forgotten them (again). While remote administration has reduced the need to physically reactivate and reset passwords in most scenarios, a copy of L0phtcrack still remains in every experienced admins ‘toolbox’. Of course, having to reboot the system and use a copy of Bart PE or other portable OS’ to run L0phtcrack has a PITA factor all its own.
Well, it seems that entrepreneur Jonty Lovell has done something about it as the all new – and fully funded – Password Reset Key has been designed to take the hassle out of this common issue. In fact, as long as you have physical access to the system even home owners can now reset their forgotten password within mere moments.
The secret to the Password Reset Key is the fact that it combines a key shaped 1GB flash drive – available in black, stainless steel, or ‘gold’ – with a simple OS that auto-loads his custom software upon startup. Just as with L0phtcrack, with a simple click or three, you can scan, reset and even test how secure a given systems login passwords are. Because of its ‘key’ form factor, it will be hard to lose as you can simply stick on your keychain and always have it close at hand. However, be warned that this $15 – $50 device (depending on which option to choose) may get you in trouble with your IT staff as resetting the ‘administrator’ password will greatly ‘annoy’ them if they find out.

Corsair continues their reputation for high speed, high quality USB products. This year at the CES 2014 show Corsair is showing off their new Voyager Go USB drive.
Two improvements with this device:
1) The USB includes a standard USB connector and a microUSB connector. This addition makes it easier to store files from a portable device directly to the flash memory.
2) The USB cap and USB body include a loop so when connected with a lanyard you no longer have the option to lose the cap. This is the first that I’ve seen with a cap/body configuration like this…and it should have happened years ago.
The Corsair Voyager Go USB is available as a 3.0 device in 16, 32 and 64GB capacity. USB 3.0 can boost transfer speeds in excess of 135MB/s however we must realize this spec is not real-world environment.

It is all over the internet, the universal USB connector; however, it is difficult to find the physical design or look of the connector. Most websites are posting old style 2.0 or 3.0 connectors. From reading through the USB.org documentation, we have the following physical design specs.
From the notes in the document, these designs could change, but at least we have an idea.

Is Checksum or CRC better for checking data written to USB flash drives?
This post is to give the general user an idea of what verification method is better for writing data to a flash drive. There are reference links at the bottom of this post which dive much deeper into the two methods of verification if this simple overview is not enough.
The short answer is Cyclical Redundancy Check or CRC is the best method for checking data written to a USB flash drive.
Many believe a checksum is the best method to verify data written to a flash drive (most popular is MD5). I believe this is favored because it is easier to understand how the verification works, and also easier to implement. However, there are flaws in checksum verification and therefore not suitable for verification of data written to a flash drive.
What is the difference between Checksum and CRC verification? The checksum method uses addition in its math calculations to check whether all data was written correctly. CRC uses long division in its math calculations to check whether all data was written correctly. It is worth noting I am talking about binary long division, not the school-yard long division you so fondly remember.
Checksum methods will calculate the total bits in a packet of data and include that total checksum amount when the data is sent over communication lines. The receiver will then look at the packet, read the checksum value and then perform the same calculation to make sure everything adds up. If the calculation on the receiver’s end matches the value passed in the packet, all is good. The problem is a high probability that somewhere between the sender and receiver the bits of data are changed, corrupted or swapped yet still turn a correct checksum value after calculation on the receiving end.
Alaska Airlines passengers will now be able to use their tablets, book readers, and cellphones all the way from the gate to thousands of feet in the air.
Starting Nov. 9, passengers will be able to use their electronic devices on board the plane, and even use WiFi, at 10,000 feet in the air. Alaska Airlines will start flying its first aircraft with 110-volt and USB power outlets at every seat next month. Most of the fleet will be equipped by the end of 2014.

The Universal Serial Buss Implementers Forum or USB-IF has released their new specification, USB 3.1. The full spec will be available for download off the USB-IF website on Friday Aug 2, 2013. The new specification allows for 10Gb/s transfer rate. Of course this is optimal transfer speed without the incurrence of operating system resources trying to regulate bandwidth for multi device transfers, but none-the-less it’s a huge jump in speed for USB.
USB 3.1 cable
USB is the most versatile connector type in the computer market. Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
Originally USB was specific to connect computer peripherals such as keyboards, pointing devices, digital cameras, printers and network adapters. With the increased need for bandwidth with digital content and the faster speeds of portable storage devices and smartphones the need to increase the speed of USB has been significant.
In addition the USB specification incorporated a Power Delivery or PD protocol which can deliver up to 100watts of power over a USB cable. The PD technology must use a certified cable with the Power Delivery wiring so not all USB cables will have the PD ability. The intent is to permit uniformly charging laptops, tablets, USB-powered disks and similarly higher power consumer electronics, as a natural extension of existing European and Chinese mobile telephone charging standards.
With the increased 3.1 speeds and the power ability of 100watts per cable it appears USB has made a substantial gain in the cable of choice for manufacturers and consumers a like for connecting their peripherals to their host computers.
The USB 3.1 specification is just now in development and products should come to market in the next 8-10 months.

Planon is known for having pen-sized scanners for mobile scanning of business cards, documents, lecture notes and more. What Planon continues to do is develop the scanning technology year after year.
The company has just released it’s latest pen scanner, the ScanStik SK600V. The V is for Voice Notes. It’s now possible to scan from a device the size of a writing pen and include voice memos for the scanned document. Nice.
They have also added bluetooth connectivity, but apparently the “b” didn’t make it into the updated part number.
You can scan at 600dpi (dots per inch) and save the file to a microSD card. Once you are ready for download, you can connect to a host computer via USB and off-load all those trade show business cards (or competitors spec sheets of that product not yet released).
