**FileMaker Pro 4.1 Does ODBC for a Price** -- FileMaker, Inc. has
 shipped FileMaker Pro 4.1 for Macintosh and Windows, the latest
 version of its flagship database product. The most important new
 feature in version 4.1 is the capability to import information
 from industry standard ODBC (Open Database Connectivity) data
 sources, enabling FileMaker users to use information served via
 products like Microsoft Access 97, Microsoft Excel, Microsoft SQL
 Server, or Oracle 7. Users can create SQL queries by pointing and
 clicking through FileMaker's ODBC SQL Query Dialog, and
 experienced SQL users can enter SQL commands directly. Data from
 ODBC sources can be incorporated into an existing FileMaker
 database or used to create a new database on the fly. ODBC imports
 should be particularly useful for applying FileMaker's extensive
 reporting and printing capabilities to information stored in
 high-end database systems. FileMaker Pro 4.1 also supports special
 features of database solutions created with the FileMaker Pro
 Developer Edition (including Kiosk mode, custom Help and About
 items, and renamed Script menus) and recognizes the currency
 symbol for the euro (ECU).

 FileMaker Pro 4.1 for Macintosh requires System 7.1 or higher, a
 CD-ROM drive, and at least 8 MB of RAM (16 MB or more strongly
 recommended). FileMaker Pro 4.1 costs $199, upgrades from previous
 versions of FileMaker (and a host of competing products including
 versions of Microsoft Access, 4th Dimension, and Corel Paradox)
 cost $149. Although FileMaker is still inexpensive as database
 products go, the upgrade price for version 4.1 is $50 higher than
 Claris charged for upgrades to FileMaker Pro 4.0. Also note that
 FileMaker Pro 4.1 requires ODBC drivers to import information from
 ODBC databases; it ships with 30-day trial versions of ODBC
 drivers from Intersolv, which are certified for use with FileMaker
 Pro 4.1. These drivers must be purchased separately to be used
 beyond the 30-day trial period; pricing is not clear, but
 Intersolv charges in the neighborhood of $750 apiece for its
 DataDirect drivers. Another option would be to use ODBC drivers
 from a different vendor, which should work in many cases even
 though they aren't certified for use with FileMaker Pro 4.1.
 Frankly, unless you need ODBC access from FileMaker (and can't use
 a third-party SQL plug-in with FileMaker Pro 4.0), the primary
 reason to upgrade to FileMaker Pro 4.1 is for bug fixes, and for
 those I'd just wait for the free 4.0v2 update FileMaker reps say
 should be available in a few weeks. [GD]

**Web Confidential 1.0.2 Released** -- Alco Blom has released a
 new version of his useful password storage program Web
 Confidential, reviewed in "Web Confidential: Securing Information
 of All Sorts" in TidBITS-441_. Version 1.0.2 addresses some of our
 minor concerns, including support for arrow keys in the Note field
 and some confusing category labels. It also groups the categories
 for easier visual parsing, fixes a crash related to the Platinum
 appearance being off, and fixes a bug that sometimes caused
 changes to be lost on save. To update from a previous version,
 download the new 384K package, install just the application, and
 replace your previous application. [ACE]

<http://db.tidbits.com/getbits.acgi?tbart=05020>


**Virtual PC 2.1.1 Update Available** -- Connectix has released a
 free updater for Virtual PC that upgrades Virtual PC 2.0, 2.0.1,
 or 2.1 to version 2.1.1. (See "Virtual PC 2.0: Not Just a Minor
 Update" in TidBITS-433_ for an overview of Virtual PC.) Version
 2.1.1 fixes a problem in Virtual PC's emulated clock chip so that
 it now correctly understands leap years, and it corrects a problem
 that sent extraneous data to the COM ports when sharing Macintosh
 folders or using drag & drop. The Virtual PC 2.1.1 updater is a
 740K download; users of Windows 95 or 98 also need a separate 770K
 Windows updater. [GD]

**Symantec Ships Norton Utilities 4.0** -- After a lengthy period
 of public beta testing, Symantec Corporation has released Norton
 Utilities for Macintosh 4.0, featuring support for both Mac OS 8.5
 and the HFS+ disk format introduced more than six months ago with
 Mac OS 8.1. (See "All About Macintosh Extended Format (HFS Plus)"
 in TidBITS-414_.) Along with a revised user interface, Norton
 Utilities components are now PowerPC-native for improved
 performance, and Norton Unerase can attempt to recover entire
 folders as well as individual files. Of course, Norton Utilities
 still features the widely used Disk Doctor and Speed Disk
 utilities for disk repair and optimization, and a bootable data
 recovery CD-ROM. Norton Utilities for Macintosh 4.0 should be
 priced around $100, and requires System 7.5.5 or greater and 16 MB
 of RAM. Although Symantec's initial press release claimed the new
 version would work with 68040-based Macs, Norton Utilities 4.0 is
 available only for PowerPC-based Macs. Symantec says owners of
 previous versions will be able to upgrade for $50. [GD]

**More USB Support from Keyspan** -- Keyspan has announced the
 expansion of its USB product line with the addition of a USB hub
 and a USB serial adapter. USB hubs enable iMac users to attach
 more USB devices to their iMacs - although the iMac has two USB
 ports, one must be used by the keyboard and mouse, and daisy-
 chaining too many USB devices can cause problems. The Keyspan USB
 hub will provide four additional USB ports for a list price of $69
 in late September of 1998. Keyspan's USB serial adapter, which is
 scheduled to ship in October of 1998 for a list price of $79,
 makes it possible for iMac users to connect serial devices like
 graphics tablets, PalmPilots, and some printers. [ACE]

**Macintosh Mailing List Directory** -- Apple Computer's Mail List
 Gnome and noted List Mom, Chuq Von Rospach, recently announced the
 availability of a totally revamped list of mailing lists related
 to Apple and the Macintosh. The Apple Mailing Lists site includes
 both lists that Apple operates and those that are independent and
 should prove a useful resource for anyone trying to find a list
 related to a Macintosh topic. If you have a list that's not
 currently included (Chuq's trying to make this a canonical
 directory), take a look at some of the currently included lists,
 then send your entry to <[email protected]>. [ACE]

**Aladdin's Desktop Magician Saws Desktops in Half** -- Is your
 Mac's desktop as cluttered as your real desktop? If so, check out
 the new Aladdin Desktop Magician from Aladdin Systems. It enables
 you to create project-based sets of files and folders that can be
 moved to or from the desktop at any time. Plus, Aladdin Desktop
 Magician can restore the positions of icons on your desktop, which
 is handy if you change resolutions, fiddle with a video card, or
 boot from a hard disk that doesn't know about your monitor setup.
 Other uses of Aladdin Desktop Magician include different desktops
 for multiple users and improved privacy by hiding sensitive items.
 Aladdin Desktop Magician costs $20; a free 30-day demo is
 available as a 476K download. [ACE]

More Ethernet Network Details
-----------------------------
 by Adam C. Engst <[email protected]>

 Not surprisingly, readers deluged us with additional comments,
 questions, and details surrounding my article "Creating a Simple
 Ethernet Network" in TidBITS-446_. Much of the discussion has
 taken place on TidBITS Talk, so to review more than I've
 summarized here, look at recent posts in the TidBITS Talk archive.

<http://db.tidbits.com/getbits.acgi?tbart=05085>
<http://www.tidbits.com/search/talk.html>


**Additional Resources** -- We received a number of pointers to
 sites containing additional information on Ethernet networks,
 including Robert Woodhead's tips-filled tale of installing an
 Ethernet network, a site containing information on structured
 cabling, the Three Macs & a Printer site, Ambrosia's Networkable
 Mac Games Networking 101 page, and John's Closet. All are worth
 investigating.

<http://www.animeigo.com/WEIRD/NETWORK.html>
<http://www.combsnet.com/networks/cable.html>
<http://come.to/three.macs/>
<http://cafe.AmbrosiaSW.com/netgames/network101.html>
<http://www.digitalmx.com/wires/>


**Fast Ethernet Backups** -- Kudos to Peter Jones
 <[email protected]> for suggesting a great reason for choosing
 Ethernet instead of LocalTalk. If you back up a several-gigabyte
 hard disk over the network, LocalTalk may prove too slow. Add
 several Macs with large hard disks to your network backup system,
 and backups may take too long to complete overnight. This is
 probably more of a problem in a small office situation than a
 home, where backup speed matters less. For more information on
 backups, see my series on the subject.

<http://db.tidbits.com/getbits.acgi?tbser=1041>


**Did We Need Hubs?** A number of people argued with our choice of
 10Base-2 in our home, saying that we wouldn't really have needed
 hubs since we could just have run more 10Base-T cable, which is
 cheap. That's generically true, but our specific situation
 involved long cable runs that utilize three holes in the outer
 walls. Running more than one or two wires simply wouldn't have
 worked physically, which is why I commented that we would have
 needed a hub at each location. If you're in a situation where the
 wire is exposed or easily strung over a drop ceiling, say, then
 you could avoid multiple hubs.


**Sharing an ISDN Connection** -- Several readers noted that the
 Sagem Planet ISDN GeoPort Adapter can provide Internet services to
 all the Macs on your network, much like Vicomsoft Internet
 Gateway, Vicomsoft SurfDoubler, and Sustainable Softworks'
 IPNetRouter. Also, Sagem has announced a USB-based ISDN terminal
 adapter for iMac users. However, Erik Buelinckx
 <[email protected]> commented that he'd found the performance to
 be slower for the other Macs on the network.

<http://www.sagem.com/en/produit2-en/spiga2.htm>


**LocalTalk Printers on Ethernet** -- In our recent iMac coverage,
 we looked closely at putting LocalTalk printers on an Ethernet
 network, so I didn't think to revisit the topic again. Even so,
 the topic confuses many people, so here are the possibilities.

* Download and install Apple's free LaserWriter Bridge software on
 a Macintosh that is connected to both your old LocalTalk network
 (which might be just the printer and that Mac) and your new
 Ethernet network. LaserWriter Bridge takes the print traffic from
 the Ethernet network and sends it out via LocalTalk to the
 printer. Remember that you won't see any speed increases in
 printing because the LocalTalk network is still a bottleneck. Some
 people have had problems with LaserWriter Bridge, although it's
 worked fine for us. Since it's free, there's no harm in testing
 it. Note that the file linked below also contains an updater for
 Apple's LocalTalk Bridge, which enables you to share all LocalTalk
 devices on an Ethernet network. However, LocalTalk Bridge isn't
 free, and I doubt you can find it for sale.

<ftp://ftp.info.apple.com/Apple_Support_Area/Apple_Software_Updates/US/
Macintosh/Networking-Communications/Other_N-C/LT_and_LW_Bridge_2.1.sea.bin>

* Buy a hardware LocalTalk-to-Ethernet bridge. A number of
 companies make these bridges - including networking vendors like
 Asante, Farallon, and Sonic Systems - and they're often used to
 make LocalTalk printers accessible to an Ethernet network. Look
 for Asante's Micro AsantePrint; Farallon's EtherMac iPrint
 Adapter, EtherWave Printer Adapter, and EtherWave MultiPrinter
 Adapter; and Sonic Systems' microPrint/2, microPrint/12, and
 microBridge TCP/IP. Prices and availability vary, but these
 devices should be in the $100 to $400 range, and some are
 available from TidBITS sponsors Small Dog Electronics and Cyberian
 Outpost.

<http://www.asante.com/Products/microprint.html>
<http://www.farallon.com/ether/adapters/iprintadapter.html>
<http://www.sonicsys.com/Products/Ethernet&Fast_Ethernet/microprint.html>

* Finally, Stephen Peilschmidt <[email protected]>
 recommended free print server software that accepts print jobs
 from a Mac on the network, then sends them on to the printer,
 freeing the Mac doing the printing from processing the print job.
 Print servers offer other capabilities as well; if you're
 interested in off-loading print job spooling to another Mac, check
 out the 1.6 MB Printdesk Lite 1.5.6 from Nine Bits.

<ftp://mirrors.aol.com/pub/info-mac/cfg/printdesk-15-lite.hqx>
<http://www.ninebits.com/>


**Dayna's Dead** -- In my list of well-known Macintosh networking
 companies, I included Dayna Communications, which is unfortunately
 now owned by Intel. Worse, Dayna officially closed its doors last
 month for future product sales. Intel has left Dayna's Web site
 active (which is misleading, since there's no disclaimer on any of
 the pages about how Dayna no longer exists) and promises to
 provide technical and warranty support. You might be able to find
 some cheap prices on new Dayna hardware for a while, but if the
 prices are the same, I encourage you to support companies that are
 active players in the Macintosh market.

<http://www.dayna.com/dayna/techsup/eoljune98.html>


**Crossover Cable Conundrum** -- Several folks observed that
 crossover cables can be a pain for regular usage. The problem is
 that unless one Mac is on when you turn on the other, AppleTalk
 won't
sense the existence of the network. The problem is primarily
 annoying, and Travis Butler <[email protected]> informed us that you
 can work around it by switching the AppleTalk control panels on
 both Macs to something other than Ethernet, closing them, and then
 switching them back to Ethernet. Travis recommended Tim Kelly's $3
 shareware FruitSpeak control strip module to simplify this
 switching. You could also use Apple's Location Manager (which
 ships with Mac OS 8.1, and is available for PowerBooks running
 earlier systems) to accomplish the same thing.

<http://www.madison-web.com/tkelly/#fs>


**Network Security** -- When I wrote about sharing files between
 computers, I should have mentioned that if you're also connecting
 your network to the Internet, you should be careful to use
 passwords. Although it's a bit less likely to affect Mac-only
 networks, I've heard of situations where PC users with cable
 modems can access their neighbors' files over the Internet
 connection.


**Long Cable Runs** -- 10Base-2 networks can have a maximum of 185
 meters (607 feet) per segment, whereas 10Base-T networks max out
 at 100 meters (328 feet) per segment. These limitations seldom
 come into play, but they're worth keeping in mind if you want to
 network multiple buildings (something we've considered doing with
 our neighbors). Data Comm Warehouse has a decent chart showing the
 variables.

<http://www.warehouse.com/datacomm/techref/chart.htm>


**Grades of Twisted Pair Wiring** -- When you buy cable for a
 10Base-T network, pay attention to the grade of the cable and the
 components. High-speed networks require higher grades of cable and
 components than voice or low-speed networks (Kee Nethery of Kagi
 once ran a LocalTalk network on hot and cold water pipes).
 Category 3 is the minimum for 10Base-T networks, and Category 5
 (called "Cat5") is the minimum for 100Base-T networks. If you're
 installing new wire, you should use Cat5 cabling, since it's the
 most likely to work for any future networks.


**Multiple Operating Systems** -- Peter Wood
 <[email protected]> asked if there's any problem
 networking Macs running different versions of the Mac OS? The
 simple answer is no, there's no problem at all. You might run into
 a situation where creating the network engenders a situation
 requiring a new version of the Mac OS, though. For instance,
 installing LetterRip Pro on our SE/30 was the only reason we
 bothered to upgrade to Mac OS 7.5.5 and Open Transport (which
 LetterRip Pro requires).


**PC Cards, Older System Versions** -- Peter Adams offered two
 minor points. First, PowerBooks using PC Cards (and possibly Macs
 using other less common Ethernet devices) to gain access to an
 Ethernet network may have "Alternate Ethernet" in their AppleTalk
 and TCP/IP control panels rather than "Ethernet." Don't be
 confused - if you have only one choice that mentions Ethernet,
 that's the right one. Second, Peter commented that if you run an
 older version of the Mac OS, you may need to install Ethernet
 drivers for your Ethernet card. Those drivers should be included,
 but if not, download and run Apple's Network Software Installer
 1.5.1 (note that it's a disk image and requires either Apple's
 DiskCopy or Aladdin's ShrinkWrap to mount). If that doesn't work,
 you'll need to call tech support.

<ftp://ftp.info.apple.com/Apple_Support_Area/Apple_Software_Updates/US/
Macintosh/Networking-Communications/Network_Software_Installer/
ZM-NSI_1.5.1.sea.bin>


**Wireless Ethernet** -- Finally, although no one mentioned it,
 I'd like to throw in a quick comment about wireless Ethernet. A
 company called Digital Ocean makes several wireless networking
 products for the Macintosh, but the products have suffered from
 high prices and poor performance. Digital Ocean's Web site doesn't
 respond, and I can't find anyone selling these products (Manta and
 Starfish for Ethernet, Grouper for LocalTalk). However, on the
 bright side, Henry Norr's MacWEEK news report for this year's WWDC
 contained a comment that Apple might be working on wireless
 Ethernet modules for a new Comms Module slot in future Macs.
 There's no telling if and when this product will come to pass, but
 in the meantime I'd like to register my vote for an inexpensive
 wireless Ethernet solution for home networking. I wouldn't even
 object to seeing it in Bondi blue.

The Race for Bandwidth
----------------------
 by Adam C. Engst <[email protected]>

 Almost a year ago, Cary Lu, noted technologist and Macintosh
 author, died after a nine-month bout with cancer. In "Cary Lu
 Remembered" (TidBITS-399_), I tried to convey who Cary was and a
 feeling for the memories he'd left for many of us.

<http://db.tidbits.com/getbits.acgi?tbart=04169>

 In that article, however, I didn't mention one final gift Cary
 left behind - a partially completed book about bandwidth that he
 was writing for Microsoft Press. He had completed much of it
 before his cancer was diagnosed, and although the radiation
 treatment and chemotherapy sapped his strength, Cary clung to the
 idea of finishing. His energy level visibly increased when he
 discussed the book, but despite valiant attempts, even Cary
 couldn't finish a book while battling cancer.

 Toward the end, I and Cary's friend Steve Manes, then writing for
 the New York Times and now for Forbes, volunteered to finish the
 book. Although we harbored no illusions of being as qualified as
 Cary, we figured that between us we could tie together the final
 pieces. Steve spent hours talking with Cary and going over the
 notes for the chapter about Internet bandwidth, and Cary explained
 some of the finer points of audio and video bandwidth to me. In
 the end, though, we were on our own with a manuscript that might
 have been 80 percent done for Cary and his original schedule, but
 which was closer to 60 percent done for us, coming in as we did
 over a year after Cary had set down some of the chapters.

 But Steve and I persevered, and digging deep within the Internet,
 we ferreted out details surrounding the history of bandwidth,
 satellite radio, and the many standards for television around the
 world. We merged and moved, edited and extended, and eventually we
 turned a manuscript into a book - The Race for Bandwidth ($19.99,
 Microsoft Press, ISBN 1-57231-513-X). Our editors at Microsoft
 Press came up with illustrations and summaries. And Cary's wife
 Ellen W. Chu provided a humorous and touching foreword along with
 acknowledgments for all those who had helped not only with the
 book, but also with keeping Cary company during his illness.

<http://www.amazon.com/exec/obidos/ISBN=157231513X/tidbitselectro00A/>


**About Bandwidth** -- The book itself contains eight chapters,
 the first four of which are essentially devoted to background
 information. It starts by describing what bandwidth is and why
 it's crucial to our information age, then steps back to trace the
 history of bandwidth. The "Thinking about Bandwidth" chapter then
 looks at common misconceptions surrounding bandwidth, such as the
 fact that a slow boat has a higher raw bandwidth than a fast wire.
 That's because bandwidth is the measure of the amount of
 information that flows from one place to another in a given amount
 of time, and sending a cargo ship with CD-ROMs from New York to
 London provides far greater bandwidth than the best Internet
 connection, even though the ship may take more than a week to make
 the crossing. The fourth of these background chapters delves into
 analog and digital bandwidth, looking at the advantages and
 disadvantages of each. In today's increasingly digital world, many
 people think that digital is "better," whereas in fact, it's
 difficult even to compare the two. For example, it's easy to say
 that an audio CD sounds better than an analog cassette tape, but
 that comparison looks not at digital and analog but instead at
 examples of high and low bandwidth methods of carrying audio
 information.

 Broadcast bandwidth, both audio and video, occupies the next two
 chapters, and coming at this from an Internet background, I found
 researching, editing, and updating these chapters to be
 fascinating. Cary covered existing types of broadcast bandwidth,
 as well as those that we're likely to see in the future. For
 instance, digital satellite radio will start supplanting standard
 analog AM and FM radio in the next few years. In the United
 States, the FCC foresees perhaps 4 percent of the population being
 able to receive digital satellite radio broadcasts in the S band
 (2310-2360 MHz) by the year 2005. Just north of the U.S. border,
 however, Canada also plans to move to digital satellite radio but
 in the L band (1452-1492 MHz), with _all_ existing analog AM and
 FM stations moving to digital satellite radio by the year 2010.
 Interestingly, Canada uses the S band for aeronautical telemetry
 applications, whereas the United States uses the L band for that
 purpose. It remains to be seen how this conflict will play out,
 but future radios may not work across the border.

 Those interested in the Internet may find the final two chapters
 the most compelling. First, Cary looks at point-to-point bandwidth
 - standard telephone lines, dedicated Internet connections,
 cellular telephones, pagers, and faxes. Perhaps the most important
 lesson in this chapter is the difference between circuit-switched
 and packet-switched communications. In circuit-switched
 communications, such as a standard telephone call, you "own" the
 virtual circuit the telephone company creates for you: the full
 bandwidth of the call is devoted to your call. That ownership is
 important, because with voice communications, silence in the form
 of, say, a pregnant pause, has meaning. But when you're
 transmitting and receiving digital data, the communications are
 inherently bursty: you receive a Web page, spend some time reading
 it, and then move on to the next one. In this situation, silence
 has no meaning, so it makes much more sense to share the bandwidth
 to even out the usage patterns. Such equality is achieved by
 breaking all communications into packets and sending each packet
 separately. The problem comes when you attempt to piggyback a
 packet-switched network like the Internet onto a circuit-switched
 network like the public telephone network.

 Having described the background of how the wires work, Cary looks
 at how bandwidth works on the Internet itself. In many ways, this
 chapter is the linchpin of the entire book, since it seems that
 everyone wants to know more about how the Internet works. That
 said, I suspect that many Internet aficionados among the TidBITS
 audience may already know most of the good points Cary makes in
 this chapter, such as the numerous places in a standard Internet
 communication transaction that can act as bottlenecks.


**Legacies** -- Steve and I volunteered to finish Cary's book not
 just because of our friendship with him but also because we both
 felt strongly that the information in the book was too valuable to
 fade away into a dusty legal estate. My suspicion is that everyone
 will come to the book with some small amount of expertise -
 perhaps thanks to an interest in shortwave radio or the Internet.
 My hope is that everyone will leave the book having acquired at
 least a deeper appreciation for the issues surrounding information
 transfer in today's world. I know I did: at times while
 researching some topic I'd stumble into Tonya's office and quote a
 classic Far Side cartoon: "Mrs. Johnson, may I be excused? My
 brain is full."

 Finally, as a gift for Cary's children - Nathaniel Chu and
 Meredith Lu - some of us set up a Web site last year so that those
 whose lives had been touched by Cary could contribute their
 thoughts and remembrances. Our plan is to print the collection on
 acid-free paper for the kids. After a year, the time has come to
 work on the final output, but we want to give everyone a last
 chance to contribute before we commit to paper. The database
 itself will remain accessible as long as we can reasonably serve
 it and as long as Ellen desires, since, along with The Race for
 Bandwidth, his other books, editorial work, short films, and
 research, it has become yet another addition to Cary's legacy.
