Equality for the able now please

“OUTRAGE OVER DISABLED PARKING FEE”

That was the headline of a recent BBC News article. It concerns a decision by a Derby hospital to charge disabled patients for parking. I ask, why haven’t they been doing so already? I am outraged too!

Disabled people have the benefit of convenient reserved parking spaces but still don’t want to pay for them. Well hard luck! I commend this hospital for doing away with the unjust favour for the disabled community. Being disabled gives you the ‘right’ to the cleanest toilets and closest parking spaces, but you want it all to be free as well? What makes you so privileged? Perhaps you should be tax exempt and have butlers paid for by the goverment too?

The Disability Rights Commission says: “This is a monstrous tax on the sick as it’s more than likely that disabled blue badge holders will have to attend hospital more often.

So the DRC admits that the disabled are already a disproportionate burden to the National Health Service, but believe that the free ride should extend to incidental living expenses now too!

By all means strive for equality, but don’t lose sight of what that actually means and damage your cause in the process. Don’t confuse a disability with just being a tightwad. You want equality? Well be careful what you wish for as you might just get it!

Stamp recycling?

What do blind people and donkeys have in common? Used stamps apparently.

I recently witnessed a usually sane friend carefully cut out and save a used stamp from an envelope, he said that he was saving them for “some woman at work who gives them to donkeys”.

Don’t get me wrong, I am an active recycler and would gladly support any scheme to reduce our waste, but how do donkeys benefit from stamps? I mentioned this riddle to a few people and was told that blind people collect them too. Time to investigate further! My early ‘research’ unearthed some other people asking the same question on Internet forums. They had been collecting away out of some halcyon notion that they were doing something worthwhile and were now desperately searching for someone to actually send them to.

First stop was the RNIB, who say:

“Stamps are sorted by volunteers and then sold to dealers and collectors. They are mostly sold by weight, if we can identify any valuable stamps they can be sold for a higher price. As a general guideline RNIB can expect to receive 90p or £1 for a pound weight of stamps.”

So it is true! In fact there are a number of charities vying for your stamp collection:

The Guide Dogs for the Blind Association say:

“… stamps can also be recycled to make money for Guide Dogs as these can be sold to collectors.”

Help the Aged are in on the act, quoting the same worth as RNIB:

“On average Help the Aged receives 90p or £1 for a pound weight of stamps.”

So my friend was not so mad after all… or was he?

All these charities conveniently supply an address to post your stamps to, but have they calculated how much it costs to send 1 pound (454 grams) of stamps? Well I will tell you. Due to it’s size your consignment will be classified as a ‘packet’ by Royal Mail and costs £1.39 to send by Second Class post.

So it actually costs more to send your stamps to the charity than they will earn back! All your diligent and painstaking collecting would amount to a nett loss of nearly 50p per pound weight of stamps.

Ignoring the postage costs and estimating that a stamp weighs 100mg, you would need to collect over 4,500 stamps to earn that £1. This values your collected stamps at just 0.02p each (i.e. collect fifty to make a penny). Perhaps this is all just a clever ruse to export our waste abroad? 😉

Please stop this ridiculous nonsense, do us all a favour and just send them the quid!

Oh, and nothing from The Donkey Santuary. Perhaps donkeys just like the taste? 😛

Silence your PC

After a bit of trial and error I have built what I consider to be an almost silent PC server. I quickly identified that most of the noise comes from fans, these are a necessary evil to cool your PC, but there are quieter alternatives. By removing the chipset fans altogether and replacing them with larger and more efficient heatsinks, I was able to cut down noise while keeping the components adequately cooled.

I chose the quietest hard disks I could find, the Seagate Barracuda 7200.7 ST380011A. Seagate claim “idle accoustics of 2.5 bels – the industry’s best” and I do agree that they are remarkably quiet.

Next was the PSU. I initially tried a Zalman AM300B-APS “ultra-quiet” PSU but this was still too noisy for my delicate ears. Instead I opted for an Etasis EFN-300 300W 0db fanless ATX PSU. As the name implies, this has no fans at all and relies on dissipating heat through metal fins exposed at the back of the unit. I was initially concerned that the fins would run hot, but it has been surprisingly cool to the touch – and reliable!

Finally I tackled the CPU (AMD Athlon XP 2200+ 1.8GHz SoA). This is the one component that runs very hot and cannot generally be cooled by passive convection. I installed a Zalman CNPS7000B-AlCu Super Flower Cooler which has a silent mode by adjusting the fan speed using the ‘FAN MATE 2’ accessory. It is not totally silent, but at low speeds is probably as good as you could expect.

Overall, my silent PC server has been a roaring 😉 success. It has been running continuously since September 2004 and none of the modified components have showed any signs of failing. The CPU and twin Seagate disk drives run at a constant 48°C, both well within normal operating temperatures.

Give me wires any day

Is it just me or is the current obsession with wirelessly enabling everything that isn’t screwed down causing a problem when you try to get all these devices to work at the same time?

In our house we have the following wireless products:

  • 802.11g Wi-Fi (2.412GHz to 2.472GHz)
  • DigiSender AV (choice of 2.414GHz/2.432GHz/2.450GHz/2.468GHz)
  • Bluetooth mobile handsets (2.402GHz to 2.480GHz)
  • Home monitoring: 868.95MHz
  • Sky Gnome audio: (choice of 863.4MHz/863.8MHz/864.2MHz/864.6MHz)
  • Sky Gnome control channel: 433.92MHz
  • DigiSender IR relay: 433.92MHz
  • Drayton Digistat: 433.92MHz
  • OneForAll remote control extender: 418MHz

As you can see, there is a lot of radio frequency conflict in the 433MHz band (designated for Industrial, Scientific and Medical applications) and my list is far from exhaustive, not including interference from neighbouring equipment such as garage door openers, CCTV and home security.

I only succeeded in making a remote control extender work after I found an ancient OneForAll device that uses 418MHz (instead of the already cluttered 433MHz) and my video sender fails every time I use the microwave! There is now a desperate need for additional unlicensed spectrum for low-power wireless home automation devices, to provide customers with an opportunity to manage their local equipment with minimal conflicts.

It is a common debate, but what are the health risks of all this localised radio energy, not to mention the combined effect of GSM and UMTS? How long before radio based denial-of-service attacks become more prevalent? Perhaps remotely tampering with your gadgets will replace knock down ginger as the preferred domestic disturbance method for today’s disaffected youth?

Like it says in the subject, give me the safety and security of wires any day!
