ZDNet is reporting that: ‘…J.S. Wurzler Underwriting Managers, one of the first companies to offer hacker insurance, has begun charging its clients 5 percent to 15 percent more if they use Microsoft’s Windows NT software in their Internet operations. Although several larger insurers said they won’t increase their NT-related premiums, Wurzler’s announcement indicates growing frustration with the ongoing discoveries of vulnerabilities in Microsoft’s products…”We saw that our NT-based clients were having more downtime” due to hacking, says John Wurzler, founder and CEO of the Michigan company, which has been selling hacker insurance since 1998…’

Algorithms in Africa
Thanks to Karsten for this link: Algorithms in Africa is a thoughtful look at some of the ethical issues of computerization in 3rd world countries with emphasis on sustainability after 1st world installers have gone home. ‘…The center, located in a rural village of southern Uganda, provides food, medical care and education to about 600 children, most of whom have been orphaned by AIDS. The conditions are austere: one book for ten children, a tiny blackboard and a roof with holes. Bram found that his skills could help at Kibaale, his help made a difference. After a year spent working with the Centre, he wanted to find ways he could continue helping the project while also letting other people know of its existence. That’s when Bram hit on the idea of “charityware” for Vim. The license for Vim says simply: “Vim is Charityware. You can use and copy it as much as you like, but you are encouraged to make a donation to orphans in Uganda. Please read the file doc/uganda.txt for details.”…’
Review: Linux vs. Windows 98 Scanning
Updated 5/24/01: Read in the comments section on sharpening algorithms. I finally broke down and shelled out some dollars for a scanner, an Epson Perfection 1240U Photo in order to add a few pics to LinuxMedNews.com. Having plunked down my money I thought I might as well do a side by side test of the scanner on Linux and Windows. I was prepared to be disappointed in Linux due to previous experience with sound card and video configuration. Read on to see what happened.
The Epson Perfection 1240U Photo I bought was $217 from Computers4Sure. It is a USB device which includes a transparency adapter for scanning negatives and other films. The scans were done on the same machine dual-booted to Windows 98SE and RedHat Linux 7.1 using the defaults for all software.
Installation for both Linux and Windows receive a B+. It came down to two issues: both had annoying installation problems but Windows was somewhat easier to install. This was negated by the bundled manufacturers software NOT being as good as Linux! Xsane (“Scanner Access Now Easy”, the Linux scanner graphic user interface program) was more cleanly laid out and better suited to its purpose than the manufacturers bundled scanning software. Xsane supported every feature of the scanner, including the transparency unit. Along with GIMP, the combination was quite powerful. What’s more, I didn’t have to install it as RedHat 7.1 already had placed it on my machine. A major minus is that I had to surf the web to find out that xsane was the scanning software for Linux and I had to find and enter some magic incantations and edit /etc/sane.d/epson.conf to get it to work. Moreover, I found the included Adobe(TM) PhotoDeluxe(tm) software bundled on Windows to be clumsy, non-standard and had an excessive number of screen changes to get tasks done. It seemed like more of an advertisement than ‘serious’ software and it became intrusive. The FilmFactory photo organizing crippleware, er, software was also a disappointment.
After paying $217 for the scanner and bundled software, I found that you had to fork over $40 more to use the full version of FilmFactory which was virtually unusable in its ‘free’ bundled form. Not good. While one of its GNOME counterparts gAlbum looks somewhat deserted on Sourceforge it provided a fair amount of functionality without the absurd limits that the out-of-the-box FilmFactory had: 5 ‘roll’ limit, and file format export limited to GIF and BMP. That is unless you wished to shell out $40 for the full version.
I did not notice any appreciable difference between scanner speed on Windows and Linux. The scanned in photos both became blocky with greater than 200% Zoom of a picture. However, picture colors were more accurate with Linux.
This picture was scanned using the Epson bundled scanner software on Windows, while this one was scanned using the xsane 0.62 software on RedHat Linux 7.1 at identical 200 dpi originally TIF file format, but converted to JPEG for display on the web. I’ve put them in a large size so that a close comparison can be done and I used default settings on all software for an out-of-box experience. The flesh tones and colors are less vibrant on the Linux scanned picture, however, the Linux scan is much closer to what the actual photograph looks like. The blue chair is too blue and the flesh tone is more colorful than the actual photo in the Windows scan. Update 5/24/01: a reader has found that the Windows scan has been put through a ‘sharpening’ algorithm that is present in GIMP, but not default. Sharpening with GIMP results in a sharper scan on Linux which you can see here.
In conclusion, which is better? I call it a tie. Once the hardware was installed, scanning software on Linux was better than Windows. Linux lost a few points for having to figure out which software did scanning, and having to edit a configuration file. But, it gained it back with the ‘bundled’ xsane software for Linux which was more suited to task than its equivalents on Windows. Scanned picture colors were more accurate on Linux than Windows. Finally, you don’t have to put up with company logo’s and splash screens at every turn with the bundled Windows software which seemed to compromise the user interface.
FreePM Does Mainframe
Updated: 1/12/2003 FreePM is now TORCH. FreePM has its latest running on IBM’s big iron through IBM’s developer works program in which you can strut your stuff on a s390 ‘enterprise class’ mainframe running a huge number of instances of SuSE Linux. Response time appears quite snappy and truly demonstrates the scalability of a portable operating system like Linux. Score a big one for medical open source.
DigitalCoast: What’s Next for Epocrates?
DigitalCoast has an extensive article on the origins of ePocrates, the successful free prescription drug database for Palm. ePocrates is getting into other follow-on applications like e-prescriptions but surprise, surprise, they may not be free: ‘…In February, ePocrates began a small rollout of its own electronic prescription writing application. Working in conjunction with PBM Advance PCS, it has developed software that allows doctors to electronically renew prescriptions via their handheld devices. Each time a prescription is renewed, ePocrates will collect a transaction fee ranging from 25 cents to $1. Snyder said the product should be available on a larger scale by the year’s end…’ Seems kind of steep to me, but they are in a position to exploit their market position. The article is a good read for those interested in how they made the original ePocrates successful.
FreeMed: ‘Stable Enough for Production’
The FreeMed project is announcing that: ‘Version 0.2.1.2 (Thelonious/CVS) is now available on sourceforge and http://www.freemed.org/. It features a lot of bugfixes from last time, but also has Lucid’s nice calendar application integrated in by way of loadable calendar modules, thanks to Chris at Lucid. This is the second in a series of CVS releases of FreeMED. Even though it is a CVS release, several locations are using this version, and it should be stable enough for a production environment.
Digital Signature Debate Enters the Mainstream
Peter Waegemann,CEO of the Medical Records Institute is interviewed by the NY Times about digital signatures and the lack of a DS requirement in the HIPPA regulations: ‘…Mr. Waegemann, a businessman who is also chairman of an industry standards group, is pressing for the use of so-called electronic signatures that would add an authentication code to each document. His concern stems from a federal law that by October 2002 will require health care providers and insurers, as well as government programs like Medicare and Medicaid, to start conducting their administrative transactions electronically…’
FreePM Announces FishBowl
Updated: 1/12/2003 FreePM is now TORCH. In an attempt to make it easier for users to report problems and make suggestions to the Free Practice Management project (FreePM) we are copying Digital Creations’ lead with a FishBowl wiki. In this method of development, all communication, decisions, arguments, and progress are visible as if everyone were working “in a fishbowl”.
Based on the hugely successful Zope FishBowl design process (Zope’s introduction page to fishbowl development here) FreePM, Inc. has installed a
similar system on the demo site.
This is a place where you can easily report bugs and make
comments or suggestions. FreePM has been designed from the
beginning based on suggestions from the FreePM and Openhealth
mailing lists. We hope to extend this community involvement by
making it easier for people to report bugs and make suggestions
while trying out the demo.
You can also enter the FishBowl from a link on the demo main
menu. This link will open a new browser window for easy access
to the FishBowl topics while testing the demo.
Feedback about the usefulness of the FishBowl and any other
FreePM topics may be directed to the FreePM mailing list.
Review: Agenda VR3 Linux powered PDA
I recently got my hands on a developer edition of the Linux powered Agenda VR3 hand held PDA device and am quite excited about it. It runs on an NEC MIPS processor (designed originally for Windows CE devices) that runs the Linux 2.4.0 kernel, XFree86, RXVT, BASH and all your favorite Linux tools. It is available now in developer edition for only $179.
It runs the VR-Linux project’s 2.4.0 kernel and a full XFree86 display on a 160×240 16 level grayscale display. It also sports a serial cable that allows you to set up a TCP/IP connection using ppp to your desktop so you can interact with it with Telnet, ftp, rsync (the most popular way to synchronize files). It has BASH running in an RXVT terminal. There is a keyboard app. with very good handwriting recognition embedded into it. You can redirect it’s X display to your desktop and vice versa. The development environment includes a cross compiler for gcc that allows compiling most Linux apps for it – the MIPS lacks a floating point processor so some changes have to be made when compiling apps for it instead of the X86 architecture. It also has a modem and can send faxes. It has an infrared port for beaming to OBEX compliant devices.
The most exciting thing for me is that Tcl/Tk is ported already to it, as is a version of PERL, PYTHON, and RUBY. You can also use the FLTK – fast light toolkit when programming in C or C++.
Over 100 Linux applications are already ported to it by the Agenda community.
I am working on a Tcl version of a wildly popular drug database for the Palm. I have a college student who is home for the summer working on it. I’m hoping to develop some useful ways to use the Tcl socket library and http to connect to my Tcl data server and web server in the Tkfp EMR.
I already have all the drugs starting with the letter “a” ported to it. It has it’s own icon in the launch pad along with the default apps provided by Agenda computing.
More info on the VR3 Linux powered PDA at http://www.agendacomputing.com
The developer edition has 8mb of RAM and 8mb of flash RAM and costs only $179 with the cradle and serial cable. The Modem costs $99. There will soon be a consumer version released with a somewhat more polished interface and more applications.
My wish list for it includes a way to connect into an ethernet jack so you could use say DHCP and move from exam room to exam room with it and say connected to your network.
The display is sometimes a little hard to see in subdued lighting conditions. Maybe my cataracts have something to do with that, my kids don’t seem to have any problems with it.
The software that ships with the developer version is not the latest version. You have to carefully read the excellent instructions provided on the developer web site and reflash it with the newest kernel and romdisk image to get the latest handwriting recognition.
