Comment Re:Can somebody explain NoSQLers to me? (Score 1) 194

Relational databases do not work well for storing hierarchical data like a file system or an object-oriented data store. They do not work well for large blobs like movie files or for unstructured documents like medical records.

Emphasis added.

This is part of the problem I have with NoSQL. It is a great solution to certain types of problem, but a lot of data is structured. Medical records are extraordinarily structured and should be stored as such. Structured medical records means portability, easy epidemiological research, better use by consumers, finer control of authorities...

Structuring medical data is hard, no doubt. But that doesn't make it unstructured data. The benefits of structure are significant. Use NoSQL for things it's good at - like storing Facebook messages - but please don't restructure your problems to fit it. Structure is good!

Submission + - Ask Slashdot: Is steganography dead?

Mjec writes: "Out of personal interest I was looking around for modern steganography tools. I remember having used steghide years ago and outguess seems popular, but neither has seen any development since 2003-2004 and they're both broken. Are there any worthwhile steganography tools out there? Is there even a maintained project?"

I am not a lawyer, but I am just about to finish law school, so should be in the next eighteen months at the outside, in Australia no less. But you still shouldn't trust me ;).

If the police are questioning you with the intent of using the information as evidence in court, they do warn you along the same lines as the Miranda rights. (in any case, Miranda was more about the fact of police having to inform about rights than the rights themselves.) You get two calls - one to family or a friend, and another to a lawyer. I don't know where you get the no-right-to-our-homes, and there's certainly a concept of illegal search, seizure and inadmissable illegally obtained evidence.

All true. The problem is none of these rights are constitutional. Whereas the government can never take away these rights in the US, thanks to the 4th amendment, they can be removed in Australia. All that's needed is for Parliament to pass a law. As we know, when it comes to law-and-order stuff, that's stupidly easy. All that's protecting us from tyranny is the goodwill of our leaders. That's why we need to complain about reform like this.

We might not have a Bill of Rights enshrined in the constitution, but we have 800 years of common law to draw on, given the courts recognise British court decisions as being relevant to Australian laws. Many of the rights you cry poor over have been ruled on in past legal cases.

Also true. But the rulings are always on the basis of interpreting legislation to be consistent with those rights where possible. We have supremacy of Parliament: if they pass a law changing the rules of evidence, the courts can't stop them. The big exception to this is political speech (and voting); these rights are guaranteed by the constitution. Limits on these can (and have been!) struck down by the courts: the Communist Party Case and just last year in Rowe v Electoral Commission. Search and seizure though are absolutely at the discretion of Parliament.

This supremacy of Parliament is why it's so important to be careful about who we elect, and to stop them from pulling shit like this.

He must have lived in a parallel universe. In the 90s it was IRC.

It probably depends what country and what age you were. In the 90s for teenagers in Britain, it was ICQ, then MSN Messenger (released 1999), with the latter being much more popular. "What's your email?" meant "What's your MSN messenger ID?". I visited some distant teenage relatives in the USA several times around this time, and remember being as surprised that they didn't know what MSN Messenger was as they were that I didn't have AIM.

Identical flow in Australia. IRC - ICQ - MSN - Facebook.

Desktop Linux Is Dead 1348

digitaldc writes with this quote from PCWorld: "It kills me to say this: The dream of Linux as a major desktop OS is now pretty much dead. Despite phenomenal security and stability — and amazing strides in usability, performance, and compatibility — Linux simply isn't catching on with desktop users. And if there ever was a chance for desktop Linux to succeed, that ship has long since sunk. ... Ultimately, Linux is doomed on the desktop because of a critical lack of content. And that lack of content owes its existence to two key factors: the fragmentation of the Linux platform, and the fierce ideology of the open-source community at large."

The step up is, as was originally identified, that RSVPs and event information are centralised. Instead of sending out updates to everyone, you place the information in a central location and people choose how they use it.

For example, when I'm invited to a facebook event it sends me an email (because I've asked it to). When I put myself down as attending, the event then appears on my calendar (because I've asked it to). If the time changes, it sends me an email but it also automatically changes on my calendar. If I decide not to go, I say "not attending" and it removes itself from my calendar. The organiser has a list of "yes", "no" and "maybe" attendees that can be used for a door list. The organiser can send a message just to the "maybes" a week out and say "hey, in or out, I need to know." All of this without having to duplicate information or use a data source that might be out of date. Sounds like an advance to me.
