Journal Journal: Improving my math skills

As a high school drop-out, here on Spain,I never made too much into maths. I began early to work (at 16 years old), and now, 12 years later, I'm an amateur photographer, I'm a 'nice' sysadmin and a good IT technician, I can survive speaking english and a pair more of languages, but I'm entering a new field I would love to master: medical and scientific imaging. The thing is, as soon as you begin studying image analysis or magnetic resonance you see that the basic arithmetic you learnt isn't e

I think that a partially correct translation would be "public broadcasting".

In spanish law, if you're going to play or broadcast for a certain number of people, highr than 5 or 10 I think, it becomes "public broadcasting", so you need to pay a license to the RIAA equivalent for the use of protected intelectual property, proportional to the actual or potential number of audience. This is valid both for radios as for bars/restaurants/_insert-any-other-kind-of-business_ (for the background music) or concert venues for the music played, and it's the owner, not the player, who has to pay.

You can always take groups of photos on the longer exposition available without trailing, and stack them in a specialized software...

Not exactly the same result, but it can be nice, due to the low light contamination and thinner atmosphere (so I presume, less aberration, sharper images...)

Also, the cold temperatures there would allow more shoots to the sensor without heating up, and then, less noise on the images...

I feel that's scary anyway :

"While not deadly like other Australian spiders, the eastern tarantulas are venomous and can grow up to 6cm (2.4in) long with a leg span of 16cm (6.3in). Despite their common name, they do not eat birds, but can kill a dog with one bite, and make a human very sick.

They are also known as whistling or barking spiders for the hissing noise they emit when they are disturbed or aggravated at close range."

Sun Microsystems

Submission + - ZFS will offer a new level of Data Protection

widhalmt writes: "According to a blog posting by Richard Elling, a further release of Suns ZFS Filesystem will introduce a technique called "ditto blocks" which will allow to automatically copy data within one storage device or meta device.

As you can set this per filesystem one can create one large metadevice out of e.g. many Raid devices and create "low security" filesystems without ditto blocks and and "high security" filesystems with instant copies spread over the different raid arrays. Even if one whole Raid Array fails, the filesystem with ditto blocks enabled will still work as normal.

This adds further levels of data protection to really important data as well as more granularity to chose how "secure" your data should be.

Some Maths about what combination of raidlevels and copy levels is best suited for your needs can be found within the posting linked above."
OS X

Submission + - Finally, procfs for Mac OS X

An anonymous reader writes: Have a burning desire to browse processes as files on your Mac like you can on most UNIX type systems? Amit Singh over at the Mac OS X Internals site has released an open source procfs filesystem for OS X. The implementation uses Google's MacFUSE which brought all the goodness of user filesystems to Mac earlier this year. In addition to things like Mach task and thread info, virtual memory, ports etc... The procfs also shows motionsensor and lightsensor data so you can simply cat these files to get sensor readings. Just like on Linux. There's also code to show TPM chip info. Cool! PS: didn't know kernel is pid 0 :)
