A guy called Derek posted photos from a personal project to nntp://uk.tech.home-automation. His work is inspiring and a lot of DIY was involved. Posted below are some specs and features, explained in his own words.

…

• Monitor mounted
• Fan and vent installed in cupboard
• Benchtop drilled
• Test fire of PC!

Some of the uses of this system:

• Recipe database (incl barcode scanning of ingredients for online supermarket ordering)
• Entertainment (MP3s, videos, TV etc from the LAN and internet)
• Web browsing
• VoIP calls
• Security (four cams around the house + alarm)
• Lighting control (possibly power down the track)

Awaiting additions:

• Globetech keyboard/trackball
• Install/config of Meedio

Looking a decade back, only a small proportion of homes had a computer. Nowadays, with costs that continue to fall and functionality that is on the rise, computers are lavishly bought, much like TV sets in the previous decade.

t has come to my attention that a few people purchase anti-virus software for Palm-powered devices. Buying virus defence for the Palm is much like buying premium insurance for a boy’s 50 watt toy motorcycle. Even free software, which claims to offer strong virus protection, will most likely hog resources for no justified reason.

In practical terms, anti virus software for Palm handhelds is utterly unnecessary. There are two known Palm viruses, which are “proof of concept”; nothing has been shown to be malicious beyond this fabricated illusion. Such viruses are created by anti-virus developers and vendors in order to create a scare and prove that Palm handhelds are potentially penetrable. The viruses have not been found “in the wild” yet and this state is unlikely to change any time soon. Remember that Palm handhelds have remote access capabilities (SSH, telnet, VNC etc.) but do not yet allow access and control from the outside. It is simply not practical because they are mobile — it is their nature to be the controlling device (master), not the controlled device (slave). You can use your remote control to affect your TV, but not the TV to affect your remote control.

There are a couple of Trojans which depend on naivety of the users. Most experienced users, however, are wise enough avoid downloading, installing, and running software which was acquired from some obscure Web site. If such applications are run, they can wreak their havoc but cannot spread from one handheld to another. Therefore, they are not infectious like the most devastating viruses which Windows users have become familiar with.

Similar selling tactics were used on the PC in the older days. Viruses like “Pong” scared users who would then purchase protection from the same people that introduced the illness in the first place. The bottom line is: do not bother with anti virus software for Palm.

LinuxDevices.com have put together a detailed review of the Aeronix Zipit instant messenger appliance which runs atop Linux and in many senses is a fully-functional PDA with WiFi built-in. The extremely low cost of $99 proves how advantageous free operating systems can be in terms of affordability. Hackers are already in the process of manipulting this device for other, more general purposes.

…priced at $99, in colors that include white, silver, blue, red, and pink. It includes an 802.11b WiFi radio, 16-color greyscale LCD with QVGA (320×240) resolution, and a thumb keyboard with rubber buttons. Also included is a stereo DAC (digital audio converter) connected to a speaker and headphone jack.

There is a growing trend which involves installing Linux on mobile devices, Palm handhelds included. It has already been determined that Palm O/S will migrate to sit in tandem with Linux if not be replaced by Linux.

t is relatively simple to incorporate valid printer-friendly versions into WordPress (see above for example). I coded up the feature early this morning; it did not require much time or effort. This involved little more than stripping of styles as well as other heavy features which contributed to clutter. More details and code at the hacks and themes page.

uch a suggestion will be best addressed to everyone in possession of a single mail account. It is nothing beyond a trivial E-mail management tip. The problem in question: When an E-mail account gets checked frequently in order to detect important incoming messages, false alarms or recurring E-mail distractions lead to disturbance and interfere with persistent work.

This is where the Urgent E-mail Account becomes of great value. By creating a new account, which is designated solely for important mail, notifications about urgent messages can be raised within just minutes. If the urgent account resides on the same domain as the normal/casual mail account, a filter can easily be created. This filter can be based on the name of sender/s or rely on a special word like ‘urgent‘ embedded in the subject line. Whenever such a filter test passes for a given messages, the message should automatically be re-directed to the Urgent E-mail Account.

Using a mail checker program, E-mail accounts which contain important messages can also be checked without consuming much computer power. By setting up a vocal/musical alarm, important messages can be configured to wake up their recipient. This type of solution is valuable if, for example, server problems occur late at night. Computer systems can automatically generate an urgent E-mail message once catastrophic events get detected. Unlike human, they are unable to make a telephone call.

Separating boxes to discern important message from the mundane

Fujitsu have introduced the bendable electronic paper. It has plenty of advantages over thin displays in existence:

• No electricity is required for continuous display
• Minimal power consumption when changing screen image
• High-level display performance
• Flexible film substrate

…electronic paper can be conveniently used in conjunction with mobile devices as an easy-to-read and portable display device.

…

Text or images from mobile phones or other mobile devices can be transferred wirelessly to larger displays for easy viewing.

Use in the home can offer more convenient digital-media devices that can be carried from room to room.

Overall, it is a very exciting innovation. On the downside, it makes the dream of a paperless office slip away.

ike many others, I keep every password stored in my Palm. Virtually any username, password and network address which I must remember will be located under one category or another in electronic form.

Quite a long time ago I discovered, much to my surprise, that others use the exact same methods as me for storing passwords. This was not the case since they were influenced by somebody else, but simply because it seemed like the right thing to do; it came naturally. Most recently, it was a technologically-oriented lady whom I noticed ended up storing her passwords in the exact same fashion as me. This begs the questions: does every Palm user adopt the same habits? And if so, was it self-taught?

No doubt there is a certain pattern — a certain adaptable method. Many start off by entering various scattered password into a single password-protected memo (the ‘piece of paper in the drawer’ equivalent). As experience develops, time takes its toll and scale becomes an issue. Passwords begin to migrate to the address book, possibly to be laid in an organic form like password under the field called ‘other‘ or ‘address‘ while the account name becomes just ‘name‘. In due time, even a single category in the address book does not suffice because of the ever-increasing number of accounts. Then, different categories for different passwords get created. This establishes layering, or a shallow hierarchy.

There is a huge advantage to this approach: when each and every record containing a password is marked ‘private‘, there is essentially one ‘master password’, much like a master key. The method rids you from the need to remember passwords. One password will unlock all others. It enables you to use a variety of different passwords without ever needing to memorise them.

Yet, as a final word of caution, records are not entirely safe on your computer (the PC-side). When you HotSync your data, this data is transfered and then stored unencrypted (in readable form) on your filesystem. Access to your hard-drive enabled access to your passwords, especially by a Palm-proficient intruder, perhaps an overly curious colleague. Having said that, the method fully protects your password in cases of PDA theft. I once came across all passwords of an MIT system administrator (while searching the Web for Tasks conversion tools) and informed him immediately so that he could empty corresponding Google cache. Needless to mention, he was frustrated and puzzled.

In summary, read the suggestions carefully and internalise what other people have learned from their mistakes. Be aware of the pitfalls and sensitivities of the method to intrusion. Lastly, never let your brain be consumed by a collection of crypic passwords. Remember just one master password.
