Uranium Resources, Inc. Begins Drilling at Its Los Finados Project

The first phase of the drilling program began on June 21 and is expected to be completed by the end of September at a cost of approximately $1 million. This phase of the exploratory core drilling will be done using a widely and evenly spaced program covering a grid designed to test the potential for uranium mineralization over the entire area. Specifically, the objective is to identify oxidation-reduction interfaces within the wide-spaced drilling.

 “The Los Finados project allows URI to explore for uranium in one of the largest contiguous untested land blocks in the prolific south Texas uranium district. URI’s water sampling results from our earlier testing, our analysis of local geologic trends, and the history of uranium production in the district suggest that the Los Finados property is highly prospective for the occurrence of one or more uranium deposits that can be produced by commercially viable ISR technology. Our three phase exploratory drilling will confirm what, if any, resources are present on this particular parcel in the district.

Prolific USB-to-serial on debian sid howto « All_about_network

As it happens over the time I came across a situation where I was using a Linux machine to connect to some networking boxes. Unfortunately the fact was that the only serial connection available was my personal usb-to-serial cable which I have bought quite some time ago and which was a major pain in the behind to make work under windows 7 64bit. Well long story short making it work under Debian was almost as “happy” and painful experience.

To start with there is enough information all around the Internet but the problems are as usually inconsistency and some Debian specifics. So let us have a look on the pre-requisities for this small exercise. My machine was running Debian Sid/Wheezy with 2.6.32 kernel but it works with the 2.6.38 as well and will probably work wit almost anything. The reason why I am mentioning this is that the first thing you need to find out is if you have the proper driver.  The way to see that is your driver type/make etc. you would need to plug it in and search in the dmessages (dunning the dmesg command) or in the messages file located in /var/log/messages.

As it happens in my case the usb-toserial reduction is the pl2303 and the driver included in the Debian stock kernel which is nice but not sufficient for anything to work. Now there are two possible things that might have happened when you plug the USB connector in. Either the module has been recognized an loaded automatically or you would need to load it manually (it depends on your udev configuration). The command to find out if the module is loaded already is this:

If the result is satisfactory and the module is loaded the next step is to verify that the proper device in the /dev directory has been created. This is a point where various tutorials will claim different things as this is one of the distribution-and-version-specific things. Anyway in the system I’ve described above the file is under /dev/ttyUSB0 Again this might and probably will be different on different systems. You can find what device has been created by the same means as you’ve used for finding out of the driver options – with dmesg command or in the /var/log/messages file

Once you find out the what is the device created by udev you’ll need to change two things. If you want to use the console as unprivileged user you need to add this user to the group “dialout” the second and actually more important thing is to change the group ownership of the device file in /dev The reason behind this is that all hardware is by default owned by root and the group root unless specified otherwise. that is fairly good point as normal users don’t normally have the need to access the hardware directly except for few cases and this i exactly one of those.
