Cameron’s Confused Plans for a “Cleaner Internet”

Sign me up for the perv’s list … I won’t trust a politician to come up with a sensible method of censorship, and neither should you.

Ignoring the civil liberties thing: That politicians with a censorship weapon will tend to over use it, to the eventual detriment of legitimate debate.

How is Cameron’s censorship thing supposed to work? It appears nobody has a clear idea. Probably not even Cameron himself.

It seems to be two separate measures :-

  1. Completely block “extreme” porn: child abuse images, and “rape porn”. Oddly enough, he also claimed that “50 Shades of Grey” would not be banned although there are those who categorise it as rape porn. Interestingly this is nothing new as child abuse images have been blocked for years ineffectively.
  2. An “optional” mechanism for blocking some other mysterious category of porn – the “family filter” mechanism.

Now it all sounds quite reasonable, but firstly let’s take a look at the first measure. Blocking child abuse images sounds like a great idea … and indeed it is something that is already done by the Internet Watch Foundation. Whilst their work is undoubtedly valuable – at the very least it prevents accidental exposure to child abuse images – it probably doesn’t stop anyone who is serious about obtaining access to such porn. There are just too many ways around even a country-wide block.

Onto the second measure.

This means that anyone with an Internet connection has to decide when signing up whether they want to be “family friendly” or if they want to be added to the government’s list of perverts … or possibly the ISP’s list of perverts. Of course, how quickly do you think that list will be extracted and leaked? I’m sure the gutter press is salivating at the thought of getting hold of those lists to see what famous people opt to get all the porn; the same gutter press that won’t be blocked despite publishing pictures that some might say meet the criteria for being classified as porn (see Page 3).

And who decides what gets onto the “naughty list” of stuff that you have to sign up as a perv to see? What is the betting that there will be lots of mistakes?

As we already block access by default to “adult sites” on mobile networks, I have already encountered this problem. Not as you might imagine, but whilst away on a course I used an “app” to locate hostelries around my location. On clicking on the link to take me to a local pub’s web site to see a few more details, I was blocked. The interesting thing here is that the app had no problems telling me where the pub was, but the pub’s web site was blocked. Two standards for some reason?

And there are plenty of other examples of misclassification such as Facebook’s long running problem with blocking access to breast feeding information, hospitals having to remove censorship products so that surgeons could get to breast cancer information sites, etc. I happen to work in a field where sales critters are desperate to sell censorship products, and I’m aware that many places that do install such products have the endless fun of re-classifying sites.

And finally, given this is all for the sake of the children, who thinks that children will come up with ways to get around the “family filter” anyway? It is almost impossible to completely censor Internet access without extreme measures such as pulling the entire country off the Internet – even China with it’s Great Firewall is unable to completely censor Internet activity. Solutions such as proxies, VPN access, and Tor all make censorship impossible to make totally effective. If you are thinking that this is all too technical for children, you are sorely mistaken … for a start it does not take many children able to figure this stuff out as they will distribute their knowledge.

This not to say that a censorship mechanism that you control is not a sensible idea. You can select what to censor – prevent the children getting access to information about the Flying Spaghetti Monster, but block access to other religious sites, etc. And such a product has to be network-wide, to prevent someone plugging in an uncensored device; such as using the OpenDNS FamilyShield (although I have never used it, I believe it to be a good product from independent reports). Of course even DNS blocking can be worked around, but it’s a reasonable effort.

Don’t Write Off British Manufacturing and Engineering …

It sometimes seems fashionable to put down British manufacturing and engineering such as when the well known idiot Jeremy Clarkson announced: “We don’t manufacture anything any more”.

Whilst it is true that Britain no longer makes more goods than the rest of the world combined, if you take the trouble to look you will find a surprisingly big industry. The trouble is that we all too often look backwards and compare today with the 19th century. Time to stop doing that, and actually look at today’s industry.

To quote the Wikipedia article (which has some other quite dated figures): “manufacturing output has increased in 35 of the 50 years between 1958 and 2007” and “output in 2007 was at record levels, approximately double that in 1958”. And: “In 2008, the UK was the sixth-largest manufacturer in the world measured by value of output.”

We may not make as much stuff as we used to, but what we do make is a lot more valuable.

A few points that illustrate just how well Britain is doing :-

  1. Of 11 constructors within Formula-1, 8 are based in the UK. Including teams such as Mercedes which you would quite reasonably assume were based in another country.
  2. Despite a series of governments that believe that spending money on space is a waste of time, the UK space industry is still worth £9 billion a year.
  3. BAE Systems is the third largest defence company in the world.
  4. GlaxoSmithKline is the fourth largest pharmaceutical company in the world.
  5. Of the 100 companies in the FTSE-100, around 33 can be regarded as manufacturing companies of one kind or another.
  6. A lesser known company (ARM) designs what is probably the most successful family of computer processors ever – ARM-based processors are found in 95% of all smartphones.

 

Should We Allow Ian Brady To Commit Suicide?

To ordinary people, the odious Ian Brady is as mad as a hatter. Nobody who commits the kind of crimes he is responsible for can be “all there”. Whether he is mentally ill, or legally insane is only relevant as far as deciding whether he should be kept in prison or in a secure hospital.

According to the reports on his mental health hearing, he wanted to be declared sane so he could return to prison where he would not face enforced feeding. He claims to be on hunger strike as he no longer wishes to live. For whatever reason, secure mental hospitals will force someone refusing to eat whereas prisons will not.

In terms of deciding whether he was well enough to be returned to prison, it is probable that the right decision was made. Whilst we should not blindly trust mental health care professionals, when they say he is too ill to be returned to prison, we need a very good reason to disagree.

However if Ian Brady had asked a different question; to be allowed to starve himself to death without being force fed, we would have a very different question to answer.

Normally there are very good reasons to force feed someone who is mentally ill and attempting to starve themselves. Some mental illnesses result in depression so severe that suicide seems like the only way out. But after appropriate treatment, the patient can be quite different.

Is Ian Brady suffering from this sort of mental illness? Apparently he is diagnosed as a paranoid schizophrenic, so the answer without additional information is perhaps. If he is not subject to episodes of clinical depression then there may be grounds for stopping the force feeding.

Now of course there is another question to answer here: Should we allow him to commit suicide before he has owned up to his crimes and detailed where the last undiscovered body of known victims is buried?

If we decide that Ian Brady should not be allowed to starve himself to death, it seems reasonable that we let him know the reason why and how he can work towards changing our minds.

What’s Missing From The New Mac Pro

Apple’s teaser of their replacement for the venerable Mac Pro has raised quite a few hackles “out there” amongst a certain kind of Mac Pro prospective customer. They’re wrong.

It is quite possible that Apple has done some extensive research on whether internal expansion with storage and PCIe cards is necessary or not. And it is quite possible that most of the old Mac Pros had not been expanded in this way.

But Apple are wrong too (and of course I’m right whilst everyone else is wrong  :-P): Internal expansion is important for some people, and they are quite possibly the sort of people that you don’t want to antagonise. Specifically the enthusiasts who would rather keep their storage internal, who want to add accelerator cards of one kind or another, etc.

Whilst the enthusiasts may not be the majority of Apple’s customers, they do have a certain amount of influence. People asking the enthusiasts at the moment may well get told to get an old Mac Pro right now so they are not limited by the expansion capabilities of the new Mac Pro.

And there’s a way that Apple could have done both; kept the neat design of the new Mac Pro, and allow the enthusiasts to have “internal” expansion. And it could be done by simply allowing the new form factor to expand the case through the base – allow it to “click” onto a PCIe expansion cage, or a two-drive enclosure.

Sure that would require some sort of special bus in the base, and a sensible way of attaching cases to the base in a secure enough manner. But it would also mean that the new Mac Pro was as expandable as the old without the use of the cable tangle that most external devices require.

Take a look behind most large tower PC’s and you’ll find a tangle of cables attaching screens, keyboards, mice, external drives, and odder devices. Apple’s new Mac Pro will just make this worse when they could have done something even more radical and showed the industry how to improve the situation.
