This Week’s Program

            Let’s take a look at Windows XP.

 

RegCleaner

            The program that Steve demonstrated last week – named RegCleaner – can be downloaded from this site.  It is a free program.

http://www.webattack.com/get/regcleaner.shtml

            With this program you can get rid of old and obsolete registry entries created by software that you have deleted or uninstalled.

It will remove various unused file types – entries of old software that you no longer have on your computer – remove unused DLL files – it has an automatic backup feature.

            This program is written by a 19 year old named Jouni Vuorio who lives in Finland.

 

            Zdnet has the Microsoft version of this program called RegClean – it is free to download.  The comments are that it works well – is easy to use – but documentation is very poor.  But, the strange thing is – Microsoft does not have it on their site.

Problems Printing the Handouts Lately??

            If you have been having problems printing the handouts in the past couple of weeks – it is probably because you are running Internet Explorer 5.5.  We have done many tests now – and this is what we have discovered.  We cannot print (or do a print preview) from Internet Explorer 5.5 on the handouts starting with March 13, 2002.  This handouts were all created using Word XP (Word 10).  The handouts will print out fine using any version of Netscape and they will print out when using Internet Explorer 5 or Internet Explorer 6.

            If you are using Yahoo email, you may have already discovered that Internet Explorer 5.5 has caused a problem with downloading your attachments.  This seems to be only when Internet Explorer 5.5 has been upgraded with Service Pack 1.  Possibly if you upgrade it with Service Pack 2, it will work okay.

 

File Extensions --- .DWG

            A question was raised last week about what program would create a file with an extension of .DWG. 

            When you receive a file that you can’t open, you can discover what type of program created it by visiting

                        http://www.whatis.com and choosing file extensions.

            In the case of the extension .DWG, it would have been created in AutoCad.  So, in order to open it, you would need a program that was capable of reading AutoCad files.

 


Viruses (w32.klez.E@mm  -- and --  w32.Magistr.39921@mm)

W32.KLEZ.E@MM

            We receive this virus in our email this week.  Luckily, our virus program caught it and deleted it.  But we thought we would explain about this one, since it is circulating now.

This worm exploits a vulnerability in Microsoft Outlook and Outlook Express in an attempt to execute itself when you open or even preview the message in which it is contained. Information and a patch for this vulnerability are available at

 http://www.microsoft.com/technet/security/bulletin/MS01-020.asp

This worm attempts to disable some common antivirus products.  It does large scale e-mailing using  email addresses found in local files, and Outlook and ICQ address books

It is a random subject and randomly named file (with a .bat, .exe, .pif or .scr extension) for the attachment.

The from address is randomly chosen from email addresses that the worm finds on the infected computer.  Because this worm does use a randomly chosen address that it finds on an infected computer  as the "From:" address, numerous cases have been reported in which users of uninfected computers receive complaints that they have sent an infected message to someone else.

            For information on how to remove this virus, follow the instructions found at

W32.MAGISTR.24876@MM

W32.MAGISTR.39921@MM

These viruses produce “dancing icons” on your desktop.  If the computer has been infected for two months, then the desktop icons are repositioned whenever the mouse pointer approaches, giving the

impression that the icons are "running away" from the mouse.

The first one adds an entry in the Win.ini file, while the second one adds an entry to the system.ini file.   It may add one or more registry entries also.

Five Digital Cameras

(Info from PcPhoto – February, 2002)

NIKON COOLPIX 5000

            This camera has 5-megapixel resolution.  It includes a “vari-angle” or swivel LCD panel – or you can use the large optical viewfinder.  It has a newly designed lens that incorporates three aspherical lens elements into a design that offers a 3x zoom (28-85mm in 35mm terms).  The camera offers a full range of controls from all-auto to full manual, a builtin flash and an accessory shoe for an external flash.  You can focus to .8 inch with no added accessories.

            It uses a CompactFlash card and has a list price of $1099.

OLYMPUS C-700

            This camera has a 10x zoom range.  With a 35mm equivalent focal range of 38-380mm, there are few subjects this camera can’t handle – it’s great for sports and outdoor subjects.  Zoom out and the 38mm perspective is wide enough to take storytelling scenics.

            The viewfinder is electronic, and you are actually seeing the same image that the camera’s 2.1 megapixel CCD is recording.  The electronic viewfinder is especially useful when shooting in Macro mode because it gives you an accurate view of your composition.  (The optical viewfinder on most digital cameras don’t do this – instead they force you to use the LCD when in Macro mode).

            This camera uses a Smart Media card and has a list price of $699.

CANON POWERSHOT G2

            This camera has external flash capabilities.  It has a 4-megapixel resolution.  The new chip and processing circuitry is designed to give better color and less CCD noise.  It has a 34 to 102mm in 35mm equivalent zoom lens.

            This camera uses a CompactFlash card and has a list price of $999

MINOLTA DIMAGE S304

            This camera has a 35 to 140mm lens in 35 mm equivalent.  It doesn’t include all of the advanced capabilities of Minolta’s upscale DiMage 5 and 7 cameras, but it does incorporate the most significant technology developed for them.  This model is easy to use. 

            This camera uses a CompactFlash card and has a list price of $499.

PENTAX OPTIO 330

            With a 3.34 megapixel resolution and a 3x optical zoom (equivalent to 37 – 111 mm in 35 mm terms).  It features two dual-sided aspherical elements. 

            This camera uses a CompactFlash card and has a list price of $699.

 

Inkjet Papers

(Info from PcPhoto – February, 2002)

            There are four important qualities to consider when comparing papers:  whiteness, weight, base and surface.

WHITENESS:

            Whiteness will affect the colors in your prints, and whiter isn’t necessarily better.

            For a photo with eye-popping colors that you want to jump off the page, try a “cooler”, very white paper – the extreme whiteness of the paper will make the colors in your photo appear brighter by contrast.  For older, faded images, a less-white paper often works well because it “warms” the colors in the photo.  There is no hard and fast rule on which “white” to choose.  It really all comes down to personal preference.

WEIGHT AND THICKNESS:

            Some papers are extremely thin and could suffer ink bleed-through; this is especially a concern when printing on both sides of the page.  Also consider your end use.  A more durable, heavy-weight paper will definitely give you longer life on projects like brochures that are intended to be handled.

BASE:

            Base, in regard to paper, is the actual makeup of the paper.  The range of possibilities runs from photo papers to canvas to film.  The base of your paper will affect the feel of your print and can affect color vibrancy and saturation as well as details in the image.

SURFACE:

            The surface of the paper will have the most dramatic ability to change the look of your print.  Coated papers designed for use with inkjet printers will give you the best results.  Glossy surfaces are very good for bright colors, but like traditional photographs, they are easily marred by fingerprints.  Matte papers are less susceptible to fingerprints, but don’t have the same vibrancy as glossy-surfaced papers.  Additionally, there are many archival papers with varying “finishes” – such as velvet, satin or pearl. 

            Another consideration is print longevity.  Most inkjet prints won’t last more than a few years when made using standard papers, and inks, especially if they are exposed to lots of sunlight.  If this is a concern for you, look into papers like Epson’s new Colorlife and HP’s Colorfast, both of which promise extended print longevity and fade resistance.  Be aware, that some of the long-life papers require extra drying time and may be subject to color shift during drying.
