As someone who recently jailbroke his iPad2, its one of the best things to ever happen to my iPad!

I bought a WiFi only model - as for my purposes, the onboard GPS is *very* substandard. When then trying to use a normal bluetooth GPS, I find out that you need a GPS that speaks "Apple" at $99USD + shipping to your country. After the jailbreak, a $5 donation to the guy who wrote a part of a bluetooth driver and bingo, now it works with ANY bluetooth GPS.

Theres also this awesome extension called "Mail Extender" that adds all the features that mail clients have developed over the last 10 years when Apple decided that you shall not send anything but plain text emails.

Thankfully, I live in a country where console modchips and other methods for device compatibility are 100% legal - and tested in court.

I wonder how this will affect radio propagation... From the brief bits that I learnt many years ago, a charged atmosphere reflects HF radio much better making low powered communications across the globe possible.

Someone who understands more about this than I do able to enlighten me a little?

Its interesting how TFA says most disabled IPv6 support after the day - however:

host www.v6.facebook.com
www.v6.facebook.com has IPv6 address 2620:0:1cfe:face:b00c::3

# host ipv6.google.com
ipv6.google.com is an alias for ipv6.l.google.com.
ipv6.l.google.com has IPv6 address 2404:6800:4006:800::1011

Looks like of the 3 listed, only 1 backed out - Bing.

Has anyone stopped to think about piracy for a second? The BIOS loaders just about make Win7/Vista/Server2008 anti-piracy a joke. It circumvents it completely.

I figure if this actually does what it sounds, the main aim is to close the door on the bios loaders that prevent any kind of effective copy protection on Windows... If they could do it for x86, they would.

Its been a long time since I've posted here on Slashdot - and I agree with the idea of your post - however I would not recommend ANYONE currently doing any new rollout to use CentOS. After just getting a heap of updates pushed through for CentOS 5.x that are mostly security and bugfixes that are mostly a few months old, I would highly recommend using Scientific Linux instead.

You can find more details on Scientific Linux on their site.

In a nutshell, its still RHEL (with a few minor changes), however updates seem to be delivered on time and with minimal delay. The project also doesn't seem to have the infighting that has infested the CentOS world.

It doesn't quite work like this. A gyroscope is set to a point in space and will always track that point. An artificial horizon will always show relative to the horizon. Angle of attack however is different as it has no bearing on the actual angle to the horizon. To explain this a little better, I shall go into a bit of detail and mention a little bit of aerodynamic theory.

Usually, a wing generates the most like with the least drag at about a 4 degree angle of attack (AoA). This is handy to know. When an aircraft starts its takeoff roll, the wing will usually be about 4 degrees above the horizon. As you are rolling along the ground (assuming its perfectly flat), this 4 degrees is perfect for maximum lift.

This changes when the aircraft raises its nose. The AoA increases (usually to 10-14 degrees) at rotation, but as the relative airflow changes to the aircraft climbing, the AoA will drop back to about 4 degrees. At this point, the aircraft nose will *still* be 10-14 degrees nose up. As the airflow is not parallel to the earth (as the aircraft is now climbing) it is quite different to the pitch of the aircraft.

For this reason, it is impossible to get an AoA from a gyro - you need to measure exactly where the air is coming from - not the pitch of the aircraft.

Exactly - and isn't this the whole idea on how this is supposed to work?

I think you're probably the majority. When I decided to take the leap out of IT nearly 3 years ago now, I was on roughly the same wage as I first started in IT nearly 10 years earlier. Yes, it was a little better, but nowhere near what I would expect.

My positions were:
1) Desktop support / network admin - first ever IT job - ~$40k AUD
2) 3 months contracting - much more than $40k when averaged over the 3 months.
3) 3rd level network support for a telco - about 300,000 users or so - ~$48k AUD
4) VoIP design / rollout - ~$41kAUD
5) Network Operations - mid-size ISP covering AU/SG - ~$45k AUD
6) Call centre team leader - ~$41k AUD.

Then I left IT to go fly planes. Less stress. Less bullshit to deal with. More enjoyable. Go Figure.
