Hitchhiker’s Guide to the Galaxy has arrived
October 14th, 2009 under Fun, Gadgtes, Hardware, rvincoletto. [ Comments: 1 ]

The Wikimedia Foundation has just launched the first release of the Hitchhiker’s Guide to the Galaxy. I hope the next version they’ll use sub-etha to update the contents automatically. It could also come with a babel fish or a Federation tricorder…


Wireless pains
July 7th, 2009 under Computers, Gadgtes, Hardware, Life, rengolin. [ Comments: none ]

One of the good characteristics of human beings is to be able to understand other people’s pains. To impersonate them, feel what they feel and know how bad/good to them was something you did. But this post has nothing to do with it, it’s just about the pains I had, and why I abandoned having a wireless connection on my desktop.

Freedom

The first benefit of having wireless is freedom to move around. Not a particular strong one with desktops, though, but still appealing if you like to move furniture (as we do). To the desktop, the best benefit is not laying cables around the house, which for a family with kids is a big deal.

Nevertheless, you still have other cables, like USB, video, sound and especially electric cables all around, probably the same length as a network cable would be. And the benefits stop right there…

Configuration

Wireless configuration is not as easy as it should be. Most boards require driver installation on Linux and Windows (although Linux has been particular strong in wireless drivers, just not to my board). That alone makes your installation of the OS a pain, as you have to install it locally, install the drivers and then update it.

Another problem is that you have to set up passwords and keys, which nowadays is more a user configuration. You can’t just start up all stuff (like sshd or web servers) before you actually log in. It means, before you say it’s a geek thing, that you can’t turn on your computer and log in remotely without logging in locally, if you don’t fiddle with the wireless/network configuration of your “easy-to-use” desktop.

Not to mention that, if you have a home server and want to mount the filesystem over the network, you can’t. Once you fiddle with the configuration and manage to allow it, it still disconnects on log-off and blocks your mount points to unmount themselves cleanly. All in all, the wireless network was designed specifically to laptops on-the-go and not to any other kind of device.

It is true that this issues are being resolved in Linux (drivers, global configuration) but it’s still a good source of problems for the day to day use.

Reliability

Wired networks have a very stable communication channel. If no one is cutting your cables or laying it around NMRs you’re very likely safe from interferences. Once the connection is established, the likelihood of it falling down is very, very low and if something do happen, it’s probably server related (i.e. it crashed) than any cable/card issue.

On the other hand, wireless connections are completely unreliable, prone to errors in transmissions, channel overuse (especially problematic on overcrowded areas like most cities) and walls. Most programs are not ready to accept huge delays on transmission.

I’ve put my router on top of the printer and bought an antenna booster, changed to a channel far away from all others in the area. The speed has increased a bit, but the reliability is still bad. It often lags, slow down and the latency is just not the same with cables.

Conclusion

Obvious as it is, wireless desktops are not rare. Many of my tech savvy friends (and me), have opted for wireless connection on their desktops in favour of a safer bet, mostly because of cabling issues. I’ve been using wireless for all my needs (desktops, laptops, mobile phones) for over three years now and I can say that I’m more dissatisfied than happy about it. This is why I’ve decided to have a long white cable around my sofas and TV set. Luckily, my power cable is also white, and as I can’t get rid of it (yet), it blends nicely.

Even my boot efficiency (boot and login) increased a lot (about 2/3 of the time), I have no more mount issues, using the server’s shared drives is easy and fast, gaming issues are over and browsing has lost a source of problems.

It’s not all roses, though. When I had the drive mounted via USB, things were a bit faster (my router is 100mbps, unfortunately), but still way better than wireless. Besides, I now have a printer and scanner server!


How green can you get?
April 9th, 2009 under Gadgtes, Life, Technology, World, rengolin. [ Comments: 1 ]

Recently the whole family has been engaged in a complete greenification and organification. We prefer regional organic food (fruits, vegetables, meat, dairy products) than regular ones. We recycle everything we can, even if that means a car trip to the recycling centre every now and then.

But the recent trip to Scotland made us to want a new car, and the new car we wanted wasn’t green at all: the Toyota’s Rav4. It took me a while to have courage to actually buy one, but in the week I was listing them to get one on the local Toyota dealer, I saw a talk by Prof. David MacKay at ARM and changed my mind…

Besides being one of the key world figures on information theory, inference and learning, he’s also pushing hard on sustainable energy. His talk was great and it was then I figured out how much difference you can make with little things. Not getting planes unless you really have no other choice, changing your car to something greener and buying food from local markets does make a big difference.

It was then that we bought a Toyota Prius. I have to say that I’m impressed. Not only it runs on battery for quite a while, but the petrol engine is super effective, only turns on when needed and doing 60mpg (21 km/l) at constant speeds. Not only that, but the amount of gadgets and technology they put in those cars is amazing.

I’m not saving the world, I know, but does help a lot. If those cars were more common, if the globalization used more internet and less aeroplanes, and if people ate more local food, maybe we could reduce the energy footprint and than sustainable energy could be viable.

One thing is for sure, people do need to change their attitude towards life and comfort and be prepared to live more and complaint less.

Geeks United! It’s time to recycle!
June 7th, 2007 under Computers, Fun, Gadgtes, Technology, rvincoletto. [ Comments: 6 ]

It’s time to recycle using your hand craft abilities!

Computer Chip Trivet

Don’t you know what to do with those old computer chips laying around? What do you think about a stylish trivet? Instructions are simple to follow: all you need are some computer chips , grout, adhesive, and a tile square.

Once you’re all finished, you’ll have a nicely geekified trivet for all your hot stuff.

You’ll really impress your geeky friends with this genuinely useful kitchen tool that you can make: a trivet built out of old computer chips.

Follow this link for full instructions.

Hard Drive Wind Chimes

The drive platters themselves are also quite remarkable: precisely made aluminium patters with a surface not unlike recording tape. The disks make a lovely clear note if you strike them, so it was only natural to make them into a set of wind chimes.

An interesting side effect is that the shiny shiny platters reflected little spots of light into the house. Naturally, if you have cats, they’ll love it too.


Follow this link for full instructions.


Hard Drive Picture Frames

So, you’ve disassembled hard drives, taken the magnets out, made wind chimes out of the platters, and so on. One thing that you might have left over is a set of printed circuit boards. Funny shaped printed circuit boards, with holes in them.

Here’s how to turn those leftover PCBs into fabulous geek-chic picture frames.

It’s done! Hang it on something ferromagnetic!

Here’s a completed picture frame, hanging on a wire bookshelf.
