The WORST argument in support of internet filtering

There are many arguments that Senator Conroy has pulled out in support of implementing nationwide internet censorship on every Australian's internet connection — all of them bad. But the WORST, in my opinion, is that the previous government's "NetAlert" program, which provided government-funded PC software which filtered a home internet connection, was an abject failure due to low take-up.

In the last week or so I've noticed active participation in online forums with clearly pro-Conroy comments (such as one from "BTDT", who I assume works for DBCDE in some capacity, but doesn't declare it.) He makes the argument above.

The thing is, NetAlert was only an abject failure if your measure of success is widespread implementation of filtering onto people's internet connections.

Why assume this is what the public wants? The NetAlert program was extensively marketed at a cost of millions of dollars to the government, with mailouts to every household in Australia, and so on. The fact that takeup was low doesn't mean the program was a failure — it simply indicates that only a very tiny minority of people want their home internet connections filtered. Which is still the case now, given opposition to the government's planned mandatory internet filter by literally everyone except christian lobby groups. I'm yet to hear from anyone who's not affiliated with a christian lobby group who is in favour of the plan.

HOW TO: set disk spindown time for hard drives in a Mac

I've recently installed an MCE Optibay with 750GB WD HDD into my new MacBook Pro, alongside the 512GB SSD I got from Apple, providing me with a beautiful 1.25TB of total storage in a slim MacBook Pro. (The MCE Optibay replaces the optical drive in the MacBook Pro, allowing you to install a second 2.5" hard drive of your choice securely in its place.)

I'm planning to use the 750GB Optibay drive for storing music and video files, since they don't need high performance, and the drive can be allowed to spin down when I'm not listening to music or watching videos, which seems like an ideal arrangement from a power efficiency perspective.

However, by default OS X seems to take about 10 minutes to spin down the drive after it was last accessed. I found a great tip on MacOSXHints.com which describes how to set the system spindown time — you just open up a Terminal shell and type:

sudo pmset -a spindown 1

(where 1 is 1 minute; 0 disables entirely).

So now, my Optibay drive spins down one minute after it was last used — perfect! (Especially good since my MBP is near-silent with the SSD just in use, thanks to Apple's really quiet fans when running at their default 2000rpm, and the WD hard drive in the Optibay is actually quite noisy — it's an audial relief when it spins down!)

The same tip above can be used to disable spindown if you don't want it to happen.

The only thing I'm wondering is what effect a spindown has on an SSD, if any. The value set using this tip is system-wide, affecting all hard drives, so if a spindown did happen to put the SSD into some sort of powersaving mode that might not be ideal, however, I haven't noticed anything yet.

HOW TO: plug a compact flash card into the MacBook Pro SD card slot

Like other MacBook Pro owners, I find Apple's choice of SD card slot for their sole card reader in the MacBook Pro annoying — basically all Digital SLR cameras except for the dinky low-end ones still use the larger Compact Flash cards. As a result, I still have to dig out a USB card reader every time I want to download pics from my D700.

It occurred to me today, though, that since SD cards are smaller than CF cards, perhaps someone has made an SD-to-CF adaptor. Lo and behold, a little Google searching turned up several immediately.

FACFSD2 HOW TO: plug a compact flash card into the MacBook Pro SD card slotHowever, it's not quite as simple as clicking 'buy'. The ones on the market at present are either Type II (which are 5mm thick, rather than the 3.3mm of Type I, and therefore not compatible with my D700, which only supports Type I), or are Type 1 cards in thickness, but generally have the SD card poking out the back of the card a bit (e.g. 16mm) so in most cases, the camera door won't shut over it — not really an option for me.

There's a good article on SD-to-CF adaptors at CameraHacker, and a thread on Whirlpool about it, but no sign of a Type I SD-to-CF card adaptor to fit in my D700, disappointingly.

Anyone seen one that will?
