I won’t claim to be a science expert, but found this article very interesting about a DNA Reader just a little larger than a USB drive.
For years, Illumina Technology has the lead in genome sequencing. Their gear is good and from what I understand their gear is expensive. The MinION (from Oxford Nanopore ) is an inexpensive alternative with some great upsides.
The DNA sequencer is just over $1,000 at the time of this post. Traditionally, a DNA sequencer could only read about 200 basis. A “basis” is a nucleobasis which is a collection of biologicial compounds that make up the basic building blocks of nucleic acid… or DNA.
The MinION is impressive with the ability to read 900,000 basis. Also called “long reads.” With the long reads you get a better idea of the compounds making up the DNA. Although the longer reads are not as accurate as short reads, the trade-off isn’t bad. The amount of time and effort to construct a long read from a collection of short reads is considerable. The less accurate long reads from MinION and not that far off base, thus a bit of a break through.
It is simply amazing that 15 years ago the human genome was a global effort, yet today it can be done in a device no larger than a flash drive.
It could be said the top five topics for CES 2018 were robots, driverless cars, virtual reality, internet of things and drones; however, we should keep our eye on less flashy topics like our beloved USB.
We learned at CES the USB Implementer Forum is looking at the capability to increase data transfer rates up to 40Gbits/second. Translated into a more common term, that is about 5,000 MB/second.
It was reported Jeff Ravencraft, president of the USB Implementers Forum, was said this is a real possibility and the wiring currently used, is capable of such speeds.
Those who favor Thunderbolt because it’s speed capability will no longer have a debatable advantage over USB, because once this new specification is released the speed between USB 3.x and Thunderbolt would be the same, maxing out at 40Gbps.
It’s always nice to appreciate our past before looking into the future. With that said, here is a chart of the USB ports currently available:
Question: Have you ever used a WiFi printer setup? It may sound like nothing special, but trust me, once you try it you’ll wonder why you waited so long. Some printers have WiFi built into them already [Brother for only $109 >] and some printers need a wireless print server. This is where the D-Link wireless print server comes into play.
The D-Link DP-301U allows you to connect those older laser and inkjet printers to the wireless print server. Meaning everyone in your office will have access to the printers without the cables. Consider I work off a laptop and so do most others, walking around and being to print on demand is insanely convenient. You may not think so now… but that means you don’t have a wireless printer connection [otherwise you’d agree].
You can buy it from Amazon.com and includes free shipping [limited time] if you use a free shipping Amazon coupon. The unit is not refurbished.
This is indeed a great deal for everyone and you should buy it while this price is still so low.
For those into home-brew programming projects, its easy to make a microcontroller spit out some Morse code with the post shown below. What makes [pavlin’s] take on this project interesting is that it resides on a tiny USB board with an ARM processor. The design for the board is available with single-sided artwork suitable for production using simple methods like toner transfer.
The STM device has a built-in USB bootloader. It can also act as a serial port, which makes the project very simple and a bit more flexible. The only external parts are a speaker and an opt-oisolator.
The program provides a command line interface over the serial port that you can use to program the message and set other options like speed and the delay between messages.
CES, 2016. Sony releases a USB turntable, named HX500. Sony will provide backup- software for the Mac and PC and it connects via USB. From there, you can send the DSD (Direct Stream Digital) copies to your computer or device. Of course Sony would prefer you to play them back on their Hi-Res-playing Sony Walkmans.
The DSD audio is a lossless audio quality that will sound more full and rich than your downloaded MP3 file. Andy why not, vinyl records have been making a big comeback the last couple of years.
USB write protected means the USB cannot be written to. But why?
There are really only two reasons why a USB stick is write protected.
#1 The USB is corrupted in some way and is no longer working properly. It’s actually very easy to destroy a USB stick and the most common way is sending multiple write threads to the device. So for example, you decide to copy a bunch of files form your computer to your USB stick. While that data transfer is going on, you give another request to write data to the flash drive. If the second request doesn’t write protect the USB, then try sending a third command, all at the same time of course, and this will certainly write protect the drive.
#2 The USB is write protected by design. Meaning the content owner (person who put data on the drive) made the stick read only. Read only is another way of saying write protected.
How you make a working USB stick write protected is sending a
