Palm Digitizer Problems

Palm stylus

Does the following scenario sound familiar?

I have a T3 and whenever I have to re-digitize the pen (ie, reboot), it sometimes takes 30 to 40 cycles of ‘upper left’, ‘center’, ‘lower right’ before it stops.

(source: nttp://alt.comp.sys.palmtops.pilot — July 19th, 2005)

This situation often gets worse. I used to go through hundreds of such cycles at some stage. The number of necessary repetitions seemed to have gone up progressively and, at one point, I had my 8-year-old sister do it for me. I told her it was a game. I finally decided to ask the Palm community and got some suggestions. The problem turned out to have been far more wide-spread than I had anticipated.

Steve confessed about his bad experiences yesterday:

…I have had my Clié for 2 years now and never had to reset the digitizer. My two Palm T3 needed a reset at least 2-3 times each time I was powering it on. That drove me crazy and Palm didn’t acknowledged the problem while thousands of customers were complaining.

Finally, some possible solutions were offered by Aaron last night:

The mad digitizer syndrome is a mechanical defect just like a broken switch. There is software that will compensate (like DigiFix) but the only real solution is to repair the unit. Some have found that cleaning and reseating the internal cables solved the problem. If all else fails, and you’re handy the digitizer can be replaced for US$40.

So, it turns out that digitizers are easily replaceable, although soldering work is involved. Over the years, I gave up on the damaged unit and handed it over to my brother. Sadly, the issue never resolved itself. On the other hand, somebody has fewer reasons to be bitter:

I had a T2 fail on me last year with the same symptoms and Palm replaced it under warranty with a new T3! Others were not so fortunate.

Palm Anti Virus – The Scam

It 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.

Plastic troopsIn 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.

WiFi Linux PDA

Aeronix ZipitLinuxDevices.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.

Palm and Password Management

Like 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?

Palm TungstenNo 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.

Free Emulators

Sonic

I discovered this long-standing site with a large number of links to just about any emulator type for a variety of operating systems. The ones of interest to me were Palm, Super Nintendo and Megadrive emulators for Linux.

I then took screenshots of some favourite old games: Mario, Street Fighter and Sonic.

The Demise of the Desktop

Palm userSeveral sites are running an article on the recent statistical figure: laptops sales surpassed desktop sales in the States.

Will it take another 5-10 years until PDA‘s outsell laptops? Hardware is becoming smaller and cheaper; CPU speed increases rather slowly; RAM matters very little at this point where the O/S just doesn’t require it. So, smaller units might be equally good. To get a convenient workspace, one can attach an external monitor and other peripherals to the PDA while having the choice to just pull the PDA out of the pocket.

Replacing your Broken Palm

Palm M100A hardware fault in outdated Palm devices is now forcing PalmOne to pay. An enormous number of people are entitled for a replacement. The wording in Slashdot:

After years of denying the problem with bad backup capacitors, Palm is settling a class action suit. If you have a dead Palm m100, m105, or m125, fill out the paperwork, and send it in, Palm will replace it with a new unit

You can get all the necessary papers as PDF‘s from this site. Does that open to doors to similar exchange policies? Ones involving other Palm models with other known defects?
