Comment Re:More history (Score 1) 81

Another tip, completely unrelated, but if I change ANY system configuration file, I first cp -a FILE FILE.org. That way I can search the system very quickly and know what things I touched. And, of course, I comment the changes in the file and include my name so I know WHY I changed it. Has saved me so many countless times.

If you are using that workflow a better option would be to use RCS. Replace your `cp -a ..` with a co / ci (check in checkout) combo and you can get way better metadata for what you have done.

You can progress up the revision control chain through cvs/svn -> git (or others) but they can be quite complex.

For manageing simple files under something like /etc on a single host though ... RCS is great

Comment Re:Hydrogen is difficult (Score 2) 130

The plan is to not transporting molecular hydrogen (H2) but rather produce liquid ammonia (NH3) and ship that. This can use our existing industrial ammonia infrastructure, or even the exisiting petroleum distribution networks.

The other half of the solution, which CSIRO has been working on for a few years now and demonstrated last year, is to develop an efficient ammonia cracking system for use at filling stations.

Comment Algorithms cannot be "closed source" (Score 1) 196

We are talking about Law, so pedantry and precision is the way to go[*] ......

By definition an algorithm cannot be "open source" or "closed source". It might be proprietary ... but that is a different thing.

Personally, I think that using some sort of Big Data / AI / Machine Learning thing to abdicate a Judge's responsibilities would seem to be the wrong way to go, particularily if you are using them to predict somone's future behaviour -- why have a Judge at all if you are going to do that?

Furthermore, prediction is really hard, particularily about the future.

It all sounds a bit Minority Report / Pre-crime to me, and so does Frank Pasquale it seems.

Comment Re:Fingerprint are not passwords (Score 2) 242

Actually, no the article does not say biometrics are "something you know" ie. a password. It spends its entire time pointing out that biometrics make very poor passwords.

Let me quote one sentence from the article for you:
        "For them [Customs] your fingerprint is only really used to verify that you are you ..."
That was in the context of biometric passports.

That is actually the correct use of biometrics ... they are something you are -- the same as your username. They are not a substitute for a pasword

Oh ... hang on ... the article even states that in its conclusion:
"Don’t use fingerprints as if they were passwords. Being permanent and relatively-easily verified and obtained makes them great for criminal investigations or for certifying that you are who you say you are. But they’re not passwords because they’re not secret, they’re not revocable, and they’re very difficult to store securely."

Let me state that again .... fingerprints (biometrics in general) are who you are. The other two pieces are how you prove it to someone who doesn't know you and possibly can't see you.

Playing devils advocate here .... but ......

If you use the GPL as your distribution license for a book.......you would have to give away the Word ... LaTex ...(pick format).... for your book and you can't stop me distibuting derivative works as long as I give you, or make available, my derivations. That's gotta suck for your income! Selling a support contact for a book has gotta be hard work!

Unless, of course, a bibliography counts as 'source' for a textbook.

Comment Re:National ID again? (Score 1) 116

australia doesn't have a string identifier per citizen yet then(soc sec number or whatever, something assigned at birth to separate you as you)?

Australia has a Tax File Number which you apply for when you start work -- or rather start paying tax. TFN is supposed to be confidential between you and the Tax Office, though in practice any organisation that has some effect on your taxable income will ask for it. Not having/providing a TFN means you'll be paying the highest tax rate.

There were plans to create the Australia Card, back in the day, but it didn't get passed by the Senate and hence the TFN was born
