Living With A Robot Cleaner (Roomba)

Well, I have been using a robot vacuum cleaner for a few months now and it’s brilliant. No need to push around a vacuum cleaner once a week; you can set the robot going in the morning just before heading off to work and it gets going.

Of course there are a few “issues” involved :

  • If you have anything that is just the wrong height, the robot can get stuck underneath. It is short enough to vacuum under sofas and the like, but gets stuck under my coffee table, and my storage heaters. I can move the coffee table, but the storage heaters need to be blocked somehow.
  • It has not happened to me, but if you have something a little on the wobbly side it is possible that the robot could knock something off when it nudges around. In fact it is a bit more of a knock than a nudge.
  • You cannot really leave things lying around. Of course that is really good if somewhat tedious. And of course you’ll find things you thought you lost during the first week whilst it nudges all those hidden things into the light.
  • Cables need to be tied up out of the way of the robot. You may think that seating them carefully against the wall will be fine, but the robot will try and drag that cable into the middle of the room. I’m sure it found more usb cables than I’m supposed to have 🙂

Lastly, it may be worth thinking more carefully about whether you need a clock and a scheduler on the robot. I do, but have only used it once to make sure it works. It is easy enough to hit the ‘start’ button that scheduling seems unnecessary. Besides it is always an idea to give a room a quick scan to check that the robot isn’t going to try to do something you don’t want.

Now all I need is a robot that will go up and down the stairs!

Rampant EU Phobia at the Sun/EU Legislation on Horse Meat

Of course anyone who has ever kept up with the Sun (a UK newspaper famous for thinking that topless woman is news, and for being keen on the “frothing at the mouth” school of journalism) will not be surprised in the least that they are jumping up and down and screaming at the thought that the EU is daring to interfere with our right to chomp through Rebecca’s pony after it has eaten it’s last bit of grass.

The news article is here (at least for now … newspapers are notorious for moving things around). But I dare say it is more of a waste of your time than reading this blog entry.

What has gotten the Sun so excited is that the EU is proposing European-wide legislation requiring the owners of working horses (which includes “pets”, riding horses, and racing horses) to sign a declaration that they will not allow the deceased horse to enter the human food chain.

What has gotten everyone involved so excited about being asked to promise something they would not do anyway ?

Well … perhaps. It turns out the British are not quite as horrified by the idea of eating horse meat as might appear. Seems that we will quite happily tuck into Rebecca’s dead horse if there isn’t any other kind of meat available. During WWII, horse meat was regularly supplied and eaten, and quite a few people have fond memories of certain dishes.

Before judging this latest EU proposed legislation, it is worth looking into why it is proposed. The idea behind it, is to stop the carcasses of horses that have been treated during their lifetimes with drugs inappropriate for food animals from entering the food chain. In other words if we do not stop such animals entering the food chain, there are many medicines that cannot be used.

So the people protesting at this EU legislation being imposed are essentially saying that they’re happy for horses across Europe to receive less than ideal health care because they do not want to make a declaration that they won’t eat their favourite horse. Ridiculous isn’t it ?

Of course there are those who say that this is all an indication of how useless the EU is that a law that is required for mainland Europe (where horse meat is widely eaten) has to be applied in the UK where allegedly it isn’t needed. But are we sure that it isn’t needed in the UK now ? Or in the future ?

It is essentially a sensible law, and the EU is being condemned for applying it over here! Anyone would suspect that in fact all this fuss was brought about by a newspaper proprietor with an axe to grind. The thing to remember about newspapers like the Sun is that they lie … they have been caught lying many times in the past, and they are not above trying to slant news to suit their own agenda. In this case a hatred of the European Union.

Inappropriate Use Of The “Paedophile” Word

One of my pet hates is the inappropriate use of the word paedophile. If you look up the proper definition of the word it is someone who is sexually interested in children specifically prepubescent children. That means children who have not been through puberty.

Is that the same as someone who is sexually interested in post-puberty “children” ? No it is not. Yet people assume that anyone who has sex with someone under the age of consent is a paedophile. However wrong it is to have sex with someone under the age of consent, it is a different order of magnitude with a child under the age of puberty.

Even more ridiculously, people have even used paedophile to refer to anyone who expresses an interest in anyone a great deal younger than themselves. The “victims” of such “paedophiles” are well over the age of consent.

By misusing the word paedophile, we trivialise the ofense. Sex with an “adult” under the age of consent may be bad, but it is ridiculous to compare it to abusing a 2 year old.

Iranian Islamic Republic In Crisis

The BBC today is saying that that the Iranian Islamic republic is in crisis, although that probably has been the case for days now (or even years if you are interested in human rights as I am). The thing is that nobody seems to have picked up on what seems obvious to me – just how stupid the current leadership of Iran is.

If you are going to ignore the results of an election, don’t have one. Come up with some sort of fake crisis that makes one impossible. If people feel they have a say in their government and it is ignored they get a bit more annoyed than if they don’t feel they have a say.

If you are going to rig an election to come out the way you want, you should at least try to make it look honest. Doing such daft things as causing 150% (or whatever) of the electorate vote for you is not going to keep the electorate on your side. Give the electorate at least some choice in believing the results.

If people are rioting in the streets because of your rigged election, don’t say that you’ll review some suspicious bits but the result still stands. That will just make them riot harder.

At a certain level of violence in the streets, it is no longer sensible to send the thugs in. It is time to start thinking of a sensible solution.

If all this were to occur some place other than Iran, it might be more understandable – still stupid. But when the leadership of Iran acquired power in almost exactly the same circumstances ? You could almost believe that they want to destroy the Islamic republic – the protesters were not originally calling for the end of the republic, but the actions of the leadership have pushed them towards it.

Domestic Routers – Do They All Suck ?

Since upgrading my ADSL limk to the Internet, I have been hunting for a decent router to do the job. And have failed completely.

Personally I don’t think my requirements are that extreme :-

  • Dual WAN links – ADSL and Ethernet (not to be used simultaneously; just allowing users to switch between different providers).
  • 8 port gigabit switch
  • 802.11n wireless
  • Reasonably robust construction including an integrated power unit.
  • Reliability; capable of running 24×7
  • A decent command line interface connected to via ssh with the ability to upload an ssh key.
  • The ability to save and load the configuration over tftp so the configuration can be kept in a subversion repository.
  • A simple web interface.
  • A decent on/off switch on the front. Actually I don’t need this myself, but I can think of a few people who would very much like them.

Anyone know of something like this ?

Probably not.

Oh, and it should be open source to allow third-parties to “fix” the firmware along the lines of what DD-WRT, OpenWRT, and Tomato all do for certain routers. In fact the manufacturers could do a lot worse than to contract someone to add their routers to the list of routers these alternative firmwares support and ship their produce with that firmware.

Just as long as certain people in the alternative firmware world get over the weird notion that “routers” does not include anything that allows connection to an ADSL WAN link. Routers are not limited to just shuffling packets between different Ethernet segments. In fact if you look at a list of interface modules for a Cisco 7600 router (definitely not “domestic”), the Ethernet modules are outnumbered by other network interfaces.
