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!


Convergence
August 7th, 2008 under Hardware, Technology, rengolin. [ Comments: 2 ]

I’m not into writing generic posts about buzzwords but I have to admit that I’m astonished. We just got a Nokia N95 8GB last week and I’ve been playing with it since then.

It’s amazing! I’ve never used my laptop since I bought it… It has a decent web browser with Flash Lite support. All websites work perfectly: Gmail, Google, Youtube, BBC, The Register, Slashdot. Even the Google calendar works well. But the best thing is that it has wireless 802.11g support, so I don’t even have to pay a penny to browse the internet! And all major websites have their mobile versions as well automatically chosen by user agent.

Games? It supports the n-gage engine (as all new Nokia do) and has some decent games for it’s small screen. The best thing about the games is that they use a OpenGL 1.1 ES GPU on the thing. Skype, messenger, GPS, step counter etc are also available. Can it get better?

Yet, the best thing is that you can develop in C++, Java and Python! Not on the move, though… I guess I’ll have to wait a few more iterations to get a terminal and a (free as in speech) compiler and a good processor to be able to compile code while I browse the web and listen to podcasts…


A Pause for Advertising

Our long time sponsor 123 CCTV Security Camera Surveillance, that you can see under Links at our right bar, has a new website.

With a range of clients that can go from The Pentagon to the home user, they have everything for security surveillance, since External and Internal security cameras, CCTV cameras to PC security systems.

We wish luck with their new website!


DRM in external drives?
December 10th, 2007 under Digital Rights, Hardware, rengolin. [ Comments: none ]

Western Digital thinks that bundling the external hard drive with a crappy software that won’t allow you to share your own videos, music and photos is security.

A friend of mine have this disk, he uses for everything, including legal music bought over the internet and other mp3 (like my band’s songs) without DRM. It works a charm on his Mac and on my Linux, I didn’t even know that drive had restrictions.

It’s quite easy for the newbie geek to avoid DRM (especially if he/she uses Linux or Mac which is common) but the non-geek consumer will probably give up the whole thing and by a new one. If only the hardware industry would just stop and think for a second…

I wonder if the same security consultant WD used is the one behind biometric passwords… or probably they just did the same security course at Microsoft…

UPDATE: a very good article by BBC.
