Today, the 18th January UTC, my various web sites, including the surprisingly popular ITS site, joined thousands around the globe and went on strike, now, some of you may be wondering why, since I'm not in the U.S., and we only have two hosts, hosted there, the answer is rather simple.
True SOPA/PIPA will not directly affect anyone outside of the United States of America, however, when you take into account the likes of Youtube, Twitter, Wikipedia, Yahoo, Hotmail, Google and even that hopeless site that has total disregard and utter contempt for everyone's privacy - yes, facebook, are all registered entities in the U.S. and are mostly located in the U.S., therefor, SOPA/PIPA will indirectly affect all non Americans, at least in the interim, because if this does become law in the U.S. it likely wont take too long before the U.S. is bypassed for most things Internet based, remember how quickly Youtube and Google took off? It wont take long before they are replaced, so the only harm will be to themselves in the long run.
The European Court of Justice gave a preliminary opinion that will have far-reaching implications in the fight against overaggressive copyright monopoly abusers. It is not a final verdict, but the Advocate General’s position; the Court generally follows this. The Advocate General says that no ISP can be required to filter the Internet, and particularly not to enforce the copyright monopoly.
Cloud computing is nothing more than a marketing term for technologies that provide computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. (Source - Wikipedia)
Cloud computing is nothing new, it has been around for decades. Email or Web Hosting anyone? The term Cloud is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents, but in recent times, some marketing hero decided to come up with a new hype, and like all techno weenies, the media picks up on it, these stormy cloud times are rather funny, but sad.
Richard Stallman of the Open Source Software Foundation summed it up nicely in an interview with The Guardian “It’s a trap… It’s worse than stupidity, it’s a marketing-hype campaign.”
Here at home in Australia, organisations investing in off-shore cloud services could find themselves on the pointy end of legal action should the privacy of Australians be breached as a result, Victoria's acting Privacy Commissioner has warned
It might surprise you to know that making your own ethernet patch leads, cabling up ethernet sockets, in-wall or not, if, any part of it is, or can be, used on a telecommunications network, including accessing the Internet via any means at all - inclding any RF means, such as WiFi, 3G etc, is, in our wonderfully over-regulated nanny-state country, illegal.
This was however once legal, until changes were pushed (likely by industry), and the Cabling Provider Rules were introduced, previous to the CPR, there existed the Digital Data Exemption, which amongst many things made it legal for anyone to carry out such activities, paid, or hobbyist, and had been in place since 1989.
The biggest problems with getting your Email to someone is getting through the receiving ends mail servers defences.
Sadly, long gone are the days of the early 90's where spam was really only something that was heard of in a supermarket, although it had been around for years, even on ARPANET and it was not of plague proportions like it reached in the mid-late 90's through to the problem it is today.
So, in light of Murdoch's staffs criminal actions, the worlds media have been filling our airwaves with the term Phone Hacking, why, I'll never know, as it is really incorrect, no phones were actually hacked at all, no conversations were monitored in real time, no phones contacts list or stored emails or photos were ever compromised in this latest scandal.
What is actually occurring is illegal access to peoples voicemail boxes. Most of us, and yes, I bet *you*, are still using the default PIN number for voicemail. Now, most of the time we don't need to know it, since the phone networks know who we are and just give us access, but, you do know that you can access your mobiles voicemail from any phone, anywhere, at any time.
Usually when your voicemail is first activated you will or at least should be, asked for a PIN, if you did not get asked for whatever reason, your voicemail box will be using the default PIN, in 99% of the time, that is simply the last four digits of your mobile number
For decades most Data Centre's utilised raised floors to inject cool air from underneath up to the racks in a back to back arrangement, this is called the Hot aisle Cold aisle method, but for some years now this method is considered outdated and rather inefficient for Data Centre cooling.
inefficient hot aisle - cold aisle approach
This method, as seen at left, involves hot air from hardware released from the rear door of a rack into the general Data Centre airspace, to assist with some form of hot air containment, most rows of racks will be so two rows are back to back, but, this still allows for hot air mixing with cold air as they are not truly contained for exhaust.
Many modern Data Centre builders have got it right in what makes far more sense using the all Cold aisle method, which involves an overhead plenum for the hot air to be expelled into, this means only cold air in your DC, and no mixing of cold and hot air, since the idea is to keep everything cool so your valuable hardware stays at a safe operating temperate.
