Sometimes, beeing a GNU compiler manufacturer is difficult! People blame you for stuff that actually is implemented correctly. A popular mistake involves multiple pointer declarations!


char a;
char b;
char c;

The statement above can be merged into a single instruction easily:

char a, b, c;

Now take a look at this:

char* a;
char* b;
char* c;

Simplifying this with common sense leads to:

char* a, b, c;

But be careful-this does not do what you want it to. The star operator ties to the variable name and not to the type. So, you would end up with a char pointer a and two char variables b and c.

The correct way of simplification looks like this:

char *a, *b, *c;

This mistake happens often. It gets even more complicated when macros/typedefs are involved. Thus, if you ever see multiple pointers defined in a single instruction-be careful!
Did you ever have such a problem?

What do you think? Will you run Linux on your Palm when it will work well?

When the in-ear headsets were first launched, people began bickering about how they would damage people’s ears very fast. Dean Garstecki, a Northwestern University audiologist and professor just announced the he beleives In-ear headphones are very dangerous for the user’s hearing capabilities.

In short, he says that people usually turn those headsets up way too far. He reccomends wearing “big” headphones instead of the tiny in-ear ones. They are not only healthier, but also have a better bass response according to him. Read the full story here:

This column went a long way! We started at the beta tester’s shacks, moved on to your lab-and now, it will go right into your mind. Just in case you are joining in now-here are the old parts:
The art of beta testing-On unprotected betas and beta fraud
The Art of beta testing-On testers
The Art of beta testing-Completely outsourcing tests is dangerous
The Art of beta testing-Random testing is useless-structured testing rules
Releases are final-gungho coding hurts
Imagine this situation: all of your beta testers gave your final release candidate an o.k.. You could release the software right now-but then you still have that tiny idea. This feature takes just five lines of code-you go ahead and implement it quickly. Then, you test it and release the convolute created. Having the testers go over it is pointless, as:
Stuff that works+Stuff that works=Stuff that works
While this method can work well, you always risk inserting a bug. A single line of code can cause a race condition in another module. Since you dont test the program as whole, this bug can move into the released version.
My method here is simple. I disable the running configuration of the program in PODS until it is released. This way, should ‘the inner kid’ take control, the program simply desnt build-and the alert reminds me of the release candidate.

That feels better. My mind is dumped, and thus I overcame an old problem of mine. However, the ball is now in front of your feet. Tell us about your strategies!

Recently I saw an old article (2003) at PalmInfoCenter. They wrote “SoftMaker did confirm a Palm OS version is in the works, and is reported to be making “good progress”, but does not have a release date at this time”. Then, nothing happened – for two years now.

I think that TextMaker would be the best word processor for Palm OS. According to PalmInfoCenter/Softmaker it supports TrueType fonts, native reading and writing of MS Word, RTF and HTML files, images, drawings, tables, frames, forms, etc. And it would be the first word processor for Palm OS with DTP (desktop publishing) capabilities (but can we say ‘desktop’ here ;-) ?)! Just have a look at the screenshot:

So many of you should have an interest of a Palm OS version of TextMaker.

I used Google and found a poll running at SoftMaker’s homepage. There you can submit on which platform you would like to see TextMaker. So, if you are interested in TextMaker, please, vote for PalmOS !!!

Reading CNET can be fun sometimes! Anyways, I found a really impressive comment in the Nintendo revolution preview. Before you say that I went all bonkers and should retire, visit it over here:

http://reviews.cnet.com/Nintendo_Revolution/4864-6464_7-31355104.html?ctype=msgid&messageSiteID=7&messageID=1203503&cval=1203503&tag=uolst

The core points made are:

  • Expensive systems are not the way to go for the masses
  • Gamers should not be the only audience of your console
  • Hardcore gamers are not the only market
  • People like multiplayer games that can be learned easily

I beleive that this is sensible. What do you think?

Its finally out! Version 1.0 of PalmPDF has been released, and can now be found on Metaview’s website.

For those who have been in the dark lately, PalmPDF is the only free native PDF viewer for the Palm OS. Other available viewers are Docs To Go, which is alot slower, and less feature filled, and PicselViewer (or Picsel ProViewer), which also really arent available on a wide scale. I should mention ProViewer is definitely not free, but quite expensive.

Many people like the idea of firmly integrating a pen into their handhelds. However, the high price for such gadgets made many people think twice. StylusCentral is currently selling the Cross MicroPen for just 4.99$-and we review it for you!

This stylus needs to be assembled before use-it consists of the pen part and an exchangeable nib that carries the screen part AND also connects to the stylus silo. The nib needs to be pressed onto the pen firmly and also in the right direction. My hands lacked the strength for the assembly, and a small gap stayed between pen and nib. However, using a table helped!
front Cross MicroPen review

This is the thinnest stylus I ever faced in my life. I gathered a few styli in this comparison photo(Cross, Brando TT 3in1, E2 PalmOne, Vii PalmOne):
styli Cross MicroPen review
When using the stylus on a touchscreen, you actually use the rubber cone on the connector of the stylus. This is bad, as the cone will likely be damaged when carrying the handheld around. Using a rubber cone for touch screen input is a new thing for me-but it works well. You have a bit more ‘feedback’ from the Digitizer surface, and writing feels more paperlike. The thinness of the stylus is annoying though-my thumb starts to hurt a tiny bit faster than with a T3 stylus. Also, the stylus lacks a reset pin. A T3 and a TE2 could be reset with the pen tip, but a Vii was not resettable.
stylus Cross MicroPen review
Writing on paper always was a domain of Cross-and this stylus makes no difference. You ‘expose’ the pen’s tip by turning the back:
pen Cross MicroPen review
Don’t ask why, but writing with this thing almost feels better than writing with a regular ball pen. The output looks a bit better than the Brando 3-in-1 stylus, here is a comparison photo.
paper Cross MicroPen review
One can use one nib with multiple kinds of handheld-dont ask me how this works. Cross says that the pen is compatible with quite a few handhelds, StylusCentral lists additional models. I tried fitting the stylus into a Tungsten E2. The stylus fits in, but doesn’t completely disappear into the silo:
te2fit Cross MicroPen review
A Vii prototype exhibited problems with locking onto the stylus-but the configuration was useable nevertheless.

Getting the nib off the pen is hard work though.

Overall, this item is difficult to rate. It does a good job as pen and stylus! It doesnt look or feel bad either. However, the stylus has major constructively deficiencies-the universal concept has a price. The stylus tip is exposed to damages, and the fit is not perfect either. But: 4.99$ is a good argument that compensates those difficulties. And-last but not least-this still is one of the nicest styli on the market…

Some of you may still remember the Newton line of PDA’s produced by Apple(yeah, those guys). Anyways, a few people recently managed to port a Newton emulator over to the Sharp Zaurus family of Linux powered PDA’s.

The speed still is rather mediocre apperently, but the OS is said to be working. Maybe we will see this on our Linux powered LifeDrives/etc soon!

The two Boxwave screen protectors

There are two varieties of screen protectors:

First, there is the soft, film-like variety that are typically not reusable and must be replaced within 3-6 months. Their advantage is that they only add a thin, flexible barrier between the stylus and digitizer which allows for a better response.
Secondly, we come to the harder, plastic protectors. They are less flexible and provide a better protective barrier for your digitizer. The typical downside is that the user may have to adjust to pushing harder when tapping to get a response. However, many of them are reusable and often enhance the color of the screen (or lack of color for you loyal old-timers).

BoxWave allowed us to test two of their most popular screen protectors: ClearTouch Anti-Glare and ClearTouch Crystal. Both of them are from the hard variety.

Now, I would humbly call myself a “soft tapper” when it comes to using my Palm. But, both ClearTouch protectors allowed for great response for both handwriting recognition and tapping. I did have to make a small adjustment, but it took only a day or two to get used to them. I was successfully converted from being a soft protector user to a hard protector user!

The ClearTouch Anti-Glare and the ClearTouch Crystal are also both reusable. I was skeptical when I read this on the package. How could a sticky, adhesive protector be washed with soap and water and still stick to my Palm? I don’t have an answer for you, but I know that it works. I washed them both reasonably vigorously to prove BoxWave wrong, but after I dried them I found them both to be sticky again. Just be careful to dry them in an area with as little dust as possible. If you live somewhere that happens to be warm this season, then it’d be a great idea to dry them outside.
Washing one of the products

Lastly, the two products do have their differences:

The Anti-Glare protector, if examined carefully, has a bunch of micro-scratches on it. These are barely noticeable and do not degrade the transparency of the screen. The surface virtually eliminates fingerprints and minimizes glare. I found this feature very impressive.

The Crystal protector’s major feature is that it is 99% transparent. It has a glossy finish which brings out color and enhances brightness. However, I could not tell much of a difference in clarity between the two when I had them each covering half of my screen. Both do an excellent job at not dulling the brilliance of the screen.

In conclusion, both products impressed me significantly. They converted me away from using the softer, film-like protectors. I really enjoyed the unique features of each which help diversify themselves from other screen protectors. My personal preference is the Anti-Glare protector, because I am very impressed with how it handles glare and fingerprints and still maintains a smooth writing surface. Both are great products, and you won’t be disappointed in either of them.

The anti-glare protector handles the flash well
