Doesn't OS X have any filesystem-level encryption like ecryptfs or encfs on Linux? Seems like a weird oversight.
Yes it does and it is built in. But it is not supported for the boot partition.
As the parent to your post said, you can easily create encrypted disk images that grow as they are used which you can mount by double-clicking on it. OS X will then ask for the key before the image is mounted.
The difficult questions are:
- How do you manage your encryption keys?
- What is your procedure for changing them?
- How many bits of entropy does your key really have? Did you say you used AES-256?
Encryption is easy. Proper key management is hard.
The same is true for Microsoft. So why did they join the cartel?
Do you think MS is able to re-license the patents to Nokia? If they can, why couldn't Google?
There's nothing wrong with goto.
Correct. It is the labels that mess things up.
{
a = 1;
a_label:
b = 2;
return a*b;
}
When reading code, the label messes up what you know about the state of the program. What are we returning here? You have to scan the entire function and find the gotos to know.
Why do we talk about power consumption in units of kWh/year. Why not simply measure average consumption in kW (kilowatts)?
And why do we pay by the kWh and not by the MJ (Megajoule)?
Don't they teach everyone stuff like this in school?
Please mod the parent up!
The referenced article says nothing since they never did a proper reset on the SSD.
Of course OS X needs TRIM. Unfortunately, I don't know of any way to reset an SSD on a Mac. You have to remove the drive and put it in a Linux or Windows machine to reset it properly.
But the Iranians insist the nuclear facilities are for research and civil uses. It is against islam to create nuclear weapons!
So why the secrecy? Why not be open about everything and build some trust?
Most people believe that a widescreen 20" monitor gives you "more/better screen" than a "non--widescreen" 20" monitor.
The opposite is true. The 20" measurement is the diagonal of the screen. You get the largest area when the height/width is equal.
The more you increase the width (and reduce the height), the smaller area you get.
The manufacturers benefit because they can sell a 20" screen with less pixels and make it sound more desirable.
Think of a circle where the radius is the screen size...
Do you read?
Books, magazines, etc print text in portrait mode.
Heck, the newspapers even print the text in several columns to avoid very long lines, as that makes text more difficult to read. (I hate programmers that create 200-character statements on one line.)
For people using computers for text (documents, programming, etc) rather than watching movies, the vertical resolution is valuable.
The problem with this is that if I decide to patent "Online Purchasing of Movies", then I will effectivly shut off all other people and get a monopoly on it
Well, a patent IS a monopoly granted by the state to individuals or corporations.
Patents == monopolies. Let that sink in.
I am a proponent of free markets where anyone can compete. I think monopolies should be abolished. Monopolies or guilds should not exist in a free market economy.

So why should authors of software have different rules than authors of (for example) film plots?
Why shouldn't we allow patents of film plots including (for example) a teleportation device as found in Star Trek?
I am a software author. Software patents interferes with my right to publish texts that i write myself.
I think that "430 child pornography sites" is a bluff. I'm calling it. What sites? Which countries? Did the Australian authorities contact the police in those countries? What happened? Did they give up and are calling for blankets?
It needs to be asked since international lobbying groups are exploiting "child pornography" to establish censorship as being normal on the internet.
Read this:
http://christianengstrom.wordpress.com/2010/04/27/ifpis-child-porn-strategy/
Do these lobbying groups operate in Australia?
What do Australian families think about commercial entities exploiting child pornography?
'According to the latest information I have here from the [Australian Communications and Media Authority], there are 430 child pornography sites on the [World Wide Web]
Maybe Conroy could explain to Australian families why hanging a blanket in front of the sites is better than shutting the sites down and prosecute the operators? Especially since it is so easy to peer behind the blanket by using a proxy, or alternate DNS resolver, etc, etc.
Are all those sites operating from countries where child pornography is legal? Which countries and sits are we talking about?
The "computer" is not only the hardware. In My experience, software failures cause more data loss, or loss of service, than hardware failures do.
Sometimes the software fails because it is too complex to use, and the operators don't quite understand it and use it wrongly. Or the software designers haven't tested it enough.
For example, I have seen more RAID systems lose data because of failures within the disk software, than I have seen disk crashes. (I'm not saying RAID is bad, but use quality products with care and don't let RAID replace backups.)
