**RAM Doubler 2 Coming** -- Connectix has announced that it
  expects to ship RAM Doubler 2 in time for Macworld Boston this
  August. Among other changes, RAM Doubler 2 will offer a control
  panel interface, a faster compression engine, and allow users to
  triple the amount of memory your Macintosh thinks it has
  available. Rebates on RAM Doubler 2 will be available for current
  users; free upgrades will be available for recent purchasers. [GD]

<http://www.connectix.com/connect/RPM.html>


**Retrospect 3.0A Updater** -- Dantz has finally released the 3.0A
  update to its popular backup program Retrospect. The new version
  adds support for Windows Remotes, so you can now back up Windows
  machines on your network using Retrospect. Since these Windows
  machines probably aren't running AppleTalk, Retrospect 3.0A uses
  TCP/IP and Open Transport to communicate with them. The new
  version adds a few specific features including support for Sony
  DAT drives with older firmware and the ability to format 8mm
  Exabyte tapes. The update also corrects problems including
  troubles relating to RAM; better support for Arabic, Hebrew, and
  Chinese characters; and a fix to seeing spurious volumes on Novell
  servers. RAM Doubler users should note that 3.0A improves
  compatibility with RAM Doubler, and that Dantz recommends that you
  use version 1.6.2 or later with System 7.5.3. You can download the
  1.6 MB updater file from Dantz's Web or FTP site, but be aware
  that both sites are pretty busy right now. [ACE]

Web Updates and Utilities
-------------------------
  by Adam C. Engst <[e-mail]>

  With the Mactivity conference happening this week, there has been
  a ton of Web-related activity in the Macintosh world. Here are a
  few of the early announcements along with some news about security
  issues in MacHTTP and WebSTAR. Look for more new product
  announcements next week after we've had a chance to sort through
  all the press releases, announcements, and gossip for the
  interesting stuff.


**MacHTTP Mandatory Update** -- Chuck Shotton <[e-mail]>,
  author of the shareware MacHTTP and its commercial version,
  WebSTAR, has released what he calls an "important, mandatory
  update" to correct a potential security problem with MacHTTP 2.2
  and earlier versions. In certain rare circumstances, this problem
  could allow unauthorized access to files on your server. If you're
  running a previous version of MacHTTP or WebSTAR PS (the version
  of MacHTTP distributed with the WebMaster Mac book) you should
  download the complete MacHTTP 2.2 distribution from StarNine's Web
  site and then update it with the patch application.

<http://www.starnine.com/machttp/machttpsoft.html/>


**WebSTAR Updated** -- Along with the update to MacHTTP, StarNine
  also released WebSTAR 1.3.1, a minor update to the just-released
  WebSTAR 1.3 (which supports custom plug-ins for increased
  performance over similar CGIs). It turns out that Chuck Shotton
  had at one time added a custom URL to MacHTTP to display the
  copyright information to satisfy lawyers, and he expanded the
  results of that custom URL to include the basic server statistics
  that the program reports in its application window. Apparently,
  Chuck simply didn't get around to removing that custom URL while
  it was MacHTTP or during the move to WebSTAR, but did so for
  WebSTAR 1.3.1 when knowledge of the URL became public. Even though
  the URL didn't affect file security at all, many WebSTAR users
  didn't want just anyone to be able to view the statistics.

<http://www.starnine.com/webstar/webstarupdates.html>
<ftp://ftp.starnine.com/pub/updates/webstar/webstar_version_history>


**Maxum Ships NetForms 2.0 & Phantom 1.1** -- Maxum Development
  has shipped a faster and Open Transport-native NetForms 2.0, its
  popular back-end Web server tool, which enables Mac Webmasters to
  do sophisticated forms processing on their Web sites. Current
  NetForms licensees can just drop their key on the demo
  application. Also, Maxum recently shipped version 1.1 of Phantom,
  a Mac-based Web robot which builds searchable HTML indexes of Web
  sites and performs mirroring and updating of sites. Phantom is
  compatible with robots exclusion standards, and provides keyword,
  boolean, and phonetic searching among other features. Phantom 1.1
  is an upgrade to AKTIV Software's Duppies 1.0 and is free for
  Duppies licensees; new users can buy Phantom for $295 through
  31-Jul-96.

<http://www.maxum.com/>


**Lumbering in the Pacific Northwest** -- Two new applications
  from Pacific Northwest developers, Open Door Networks in Oregon
  and ComVista Internet in Washington, should help Webmasters work
  with logs. Open Door Networks' $249 LogDoor (with a $179
  introductory price from the anticipated ship date of 01-Sep-96 to
  01-Nov-96 - an evaluation version is available now) provides
  real-time logs for multiple sites on a single server that uses
  Open Door Networks' HomeDoor, and it breaks single monolithic log
  files into smaller, more manageable files. LogDoor can also
  display its real-time logs via the Web. Although LogDoor 1.0
  currently has only a basic feature set, future plans include
  things like file level logging and real-time graphing. ComVista's
  free LogRoller fills a more simple need - it works with WebSTAR to
  create a new log, rename the old one, and move the old one into a
  user specified folder. No more manual editing of huge log files to
  make them cover the correct time period! LogRoller can roll over
  your logs hourly, daily, weekly, or monthly.

Power to the Masses from Microsoft
----------------------------------
  by Tonya Engst <[e-mail]>

  Registered users of Microsoft's Excel 5, PowerPoint 4, Word 6, or
  Office 4 should keep an eye on their mail for a free CD-ROM,
  called the Microsoft Empowerment Pack for the Macintosh. The CD
  includes both the System 7.5 Update 2.0 (which updates System 7.5,
  7.5.1, or 7.5.2 to version 7.5.3; see TidBITS-318_) and System
  7.5.3 Revision 2 (which should be used on some computers running
  System 7.5; see TidBITS-332_). According to Microsoft, System
  7.5.3 makes Office applications launch faster.

  The CD also offers the Word 6.0.1a update, Internet Explorer
  2.0.1, a collection of cached Web sites, Internet Assistant for
  Word and Excel, an offer for a discount on RAM from Kingston, and
  more. Apparently, at a periodic business review, Bill Gates was
  wondering what could be done to make Mac customers happier, and
  this CD comes as the result of that discussion.

  Registered Microsoft Office 3 users (or people owning individual
  applications that comprise Office 3) will receive a mail-in card
  that they can send in order to acquire the CD, or they can call
  800/469-6520, department MCA. Unfortunately, the CD only contains
  English language versions of Microsoft software, and Microsoft
  does not currently have plans to offer it outside the United
  States or to create non-English language versions.

<http://www.microsoft.com/corpinfo/press/1996/jul96/macpckpr.htm>

  The CDs packaging oddly notes on its cover that it "may not change
  your world," a statement that confused and amused Adam to no end,
  because after opening the pack, I had rearranged its complex
  series of folds so the punch line, "it just might expand it," had
  been buried beneath several layers of cardboard. After you pry the
  CD out of its packaging, but before you use it, you may wish to
  learn from the experiences that TidBITS reader Corl Riblet
  reported. When Corl launched the Microsoft Empowerment Pack, he
  was so startled to find Microsoft Internet Explorer launching that
  - in a state of some alarm - he aborted the launch. Indeed, the
  Empowerment Pack uses Internet Explorer to run its installation
  system, so don't be startled!

  The Empowerment Pack also fails to make an important distinction
  between who needs to run the Word 6.0.1a updater and who does not.
  If you are using Word 6.0, you almost certainly want to run the
  updater in order to take advantage of the many fixes version 6.01
  offers. The Word Update/Product Info section of the Empowerment
  Pack describes some of the fixes in a general sort of way, but
  fails to provide a Web link or reference to the real scoop, which
  you can find online at:

<http://www.microsoft.com/kb/deskapps/word/q129242.htm>

  For users of Word 6.01, version 6.0.1a adds one thing, and one
  thing only - it incorporates as part of the application the Word-
  related functionality also available through the Office 4.2x
  Update for Power Mac, which corrects some crashing problems on
  Power Macintoshes (see TidBITS-289_). Installing 6.0.1a on any
  Macintosh makes sense as a replacement to 6.0; it does not make
  sense as a replacement to 6.0.1 on a 68K Mac.

  I have been unable to confirm which version of the Office 4.2x
  Update for Power Mac was rolled into Word 6.0.1a. Versions n/a and
  1.0 of the updater conflicted with the Global Village Toolbox
  extension and STF Technologies FAXstf software. Microsoft fixed
  the problem with version 1.01. According to Ric Ford's MacInTouch
  News Archive for 11-Jul-96, early versions of the Office 4.2x
  Update for Power Mac also conflict with System 7.5.3's Apple Menu
  Options control panel.

<http://www.macintouch.com/newsarch1996q3.html>

  The Empowerment Pack installer does not permit you to choose
  whether to install 68K, fat, or PowerPC version of Word 6.0.1a,
  and according to Corl (who discussed this with a Microsoft Support
  engineer), the Empowerment Pack installs a fat version, so watch
  out if your hard disk is almost full. Reports from Corl and also
  on Usenet indicate that the fat version will add approximately 4
  MB to the size of the Word application, if you didn't previously
  have the fat version installed.

  Oddly, the pack fails to include additional document converters
  available for Word, or to make any sort of reference to such
  updates. You can find out more through Microsoft's online
  knowledge base:

<http://www.microsoft.com/kb/deskapps/word/q119859.htm>

  I'd like to see Microsoft make such a CD an annual shipment. I'd
  also like to see it routinely include all the little updates
  associated with Office software, and include a rich and
  intelligent set of information and links to Microsoft's Web-based
  knowledge base.


Claris OfficeMail Debuts
------------------------
  by Adam C. Engst <[e-mail]>

  Claris OfficeMail is an interesting solution to the email problems
  of many small offices and schools. These groups want and need to
  use email to communicate within their organizations and, given the
  undeniable utility of Internet email, they also want to be able to
  send and receive mail from the Internet. For the most part, they
  generally don't have large budgets, nor do they have dedicated
  computer support people who know how to run mail servers. And,
  despite the ever-increasing popularity of the Web, many may not
  yet have dedicated Internet connections of any sort.

<http://www.claris.com/products/ClarisOfficeMail/>

  The $299 OfficeMail is a LAN email server that supports SMTP and
  POP, the main ways of sending and receiving Internet email, and
  claims to be easy to set up, with three steps for internal use and
  an additional three steps if you want to send and receive Internet
  email. I walked through the steps, and I have to admit, it's dead
  simple; Claris deserves credit for making the setup so easy. You
  can even get your own subdomain name within the clrs.com domain.

  OfficeMail comes with a 5-pack of Claris Emailer for reading
  email, which is another good move, since Emailer is a powerful
  email client with some compelling features, most notably the
  capability to send and receive email from America Online and
  CompuServe as well as the Internet. Emailer's glaring flaw (the
  way it creates an individual file for each email message you
  receive) is due to be fixed in the next version and probably
  wouldn't seriously affect the low-volume use from most users of
  OfficeMail. You can also use the free Eudora Light or any other
  POP-based Internet email program to send and receive mail from a
  Claris OfficeMail server.

  OfficeMail has reasonable system requirements, which is important
  because small offices and schools are likely to want to run the
  program on an old Mac that's sitting around. OfficeMail requires a
  68020 or higher, with 4 MB of RAM for a 68K Mac and 8 MB for a
  Power Mac. You'll want a fair amount of disk space since
  OfficeMail has to store all the incoming email on disk until the
  user checks mail - a couple of large attachments will make a small
  hard disk struggle under the load. Of course, you need an
  AppleTalk or TCP/IP network, but it need not be connected to the
  Internet because OfficeMail requires a modem (preferably a fast
  one) to send and receive Internet email.

  OfficeMail uses the modem to connect to ClarisLink, a service run
  by HoloNet using CompuServe Packet Network dialup numbers
  (presumably around the world). The fee is $39.95 per month for 10
  hours and about $5.95 per hour after that (plus a $25 registration
  fee), which is probably reasonable for the normal email
  requirements of a small office. The trick is that OfficeMail uses
  UUCP (Unix to Unix CoPy), an older protocol used primarily for
  transferring email and Usenet news.

  If you're at all new to the Internet you may not have even heard
  of UUCP. UUCP programs aren't high-profile, nor are they
  frequently updated, since UUCP hasn't changed much in a long time.
  But, you can still get UUCP accounts from some Internet providers,
  and for inexpensive email using an offline model (where your
  computer connects, sends and receives mail, and disconnects,
  preferably in an automated fashion), UUCP still works fine. We at
  TidBITS used UUCP for years until finally getting a dedicated
  Internet connection toward the end of 1994, and I wrote about UUCP
  extensively in the first two editions of Internet Starter Kit for
  Macintosh (the chapter was pulled from the print version of the
  third edition, but appears in the online version.)

<http://www.mcp.com/hayden/iskm/iskm3/pt3/ch15/ch15a.html>

  The main UUCP program for the Mac, uAccess, was marketed for a
  while by InterCon Systems as UUCP/Connect, but rights reportedly
  reverted back to Tim Endres, the developer, some time ago, and
  I've heard nothing about it since. There are two other free
  implementations of UUCP, Mac/gnuucp and uupc (which is reportedly
  slated for an upgrade soon). Check the URL below for the Mac UUCP
  software that's generally available.

<ftp://ftp.tidbits.com/pub/tidbits/tisk/inet/uucp/>

  By using UUCP and tying OfficeMail to a specific Internet
  provider, Claris removed the complexity of dealing with TCP and
  potentially PPP, both of which can prove troublesome for novices
  to set up, particularly without sufficient documentation. (There's
  a reason why the fourth edition of Internet Starter Kit for
  Macintosh devotes an entire chapter to troubleshooting advice
  related to connections.)

  In the process, Claris also opted _against_ making OfficeMail a
  full SMTP server, something that's not clear from Claris's
  propaganda about the program. Although an email client program
  like Eudora can use SMTP to connect to OfficeMail, OfficeMail
  cannot send mail out to the Internet via SMTP, as do full SMTP
  servers like the free Apple Internet Mail Server and Stalker
  Software's flexible CommuniGate system, which is available for
  free evaluation. So, if you have a dedicated Internet connection,
  you can use OfficeMail, but it must still use a modem to connect
  to ClarisLink to send and receive email.

<http://cybertech.apple.com/AIMS.html>
<http://www.stalker.com/CommuniGate/CommuniGate.html>

  Actually, that's not entirely true - you don't have to connect to
  ClarisLink. OfficeMail seems to work only with ClarisLink, but in
  an undocumented feature, you can use, or at least try to use, any
  UUCP account with any Internet provider. Claris doesn't advertise
  or document this feature because setting up a UUCP email
  connection isn't easy, but with a bit of work it should be
  possible. OfficeMail uses the Apple Modem Tool to control the
  modem, so you can change its settings to dial your Internet
  provider. Then, in the Claris OfficeMail folder, there's another
  folder called Claris OfficeMail Files. In it is a file called Mail
  Connect Script, which is a text file of the connect script
  OfficeMail uses to login and retrieve email. It's not a task for
  the faint of heart, but you could edit that script (keep backups!)
  to connect to your Internet provider instead of ClarisLink. The
  script language is unusual, but simple and documented briefly at
  the top of the Mail Connect Script file. Needless to say, don't
  expect Claris to provide any help whatsoever if you attempt this
  hack, but if you're experienced with UUCP and are helping someone
  else set up a UUCP account, it might be a good solution.

  So, if you have no dedicated Internet connection and want email,
  Claris OfficeMail is worth investigating. If you have a dedicated
  Internet connection via modem to a single Mac, but not to your
  entire network, check out CommuniGate or the combination of Apple
  Internet Mail Server and the shareware AIMS LocalTalk Bridge,
  which enables you to distribute mail internally to Macs on your
  network running Eudora Light. Finally, if you have a dedicated
  Internet connection for your entire network, try Apple Internet
  Mail Server or CommuniGate.

<ftp://ftp.tidbits.com/pub/tidbits/tisk/inet/mail/aims-localtalk-bridge-13.hqx>

  As a postscript, I wrote the first draft of this article as a rant
  after receiving and installing Claris OfficeMail partly because I
  was irritated by Claris's silly spelling of OfficeMail as
  "OfficeM@il" (same with "Em@iler"), but mostly because all the
  OfficeMail information claimed that OfficeMail supported a number
  of Internet standards, including SMTP. However, I couldn't get it
  to work as an SMTP server, nor could I see any SMTP setup options.
  I decided to check all this with Claris, and I had to talk to the
  developer before I was able to confirm that OfficeMail can't talk
  to SMTP servers, that OfficeMail uses standard UUCP, and that it
  was theoretically possible to use other UUCP accounts. The
  propaganda didn't even include UUCP as one of the Internet
  standards that OfficeMail supports - the only mention of UUCP on
  Claris's Web site is in a pricing comparison note. Those seem like
  fairly major points to me, and they deserve mention somewhere in
  OfficeMail's documentation and reviewer's guide. OfficeMail may be
  great for novices, but if it confuses sophisticated users and
  writers through incomplete documentation, it's in serious danger
  of receiving undeserved bad press.


Keeping Robots Out of Your Corner of the Net
--------------------------------------------
  by Tonya Engst <[e-mail]>

  Search engines and searching tools have become ubiquitous on the
  Internet. People flock to search engine sites in order to find
  information quickly, and the information available comes with
  startling breadth and depth. (See Kirk McElhearn's article in
  TidITS-333_).

  For instance, I just searched AltaVista for "watermelon." I've
  barely scratched the surface of my search results, but I've
  already read about the status of the Texas watermelon crop,
  scanned an article about preparing watermelon (along with
  nutritional information), and visited a Web page devoted to
  Cezanne's painting, "Still Life with Watermelon and Pomegranates."


**Indexing Robots** -- Search engines acquire much of their
  information through robots. Also known as spiders or crawlers,
  robots traverse the Web, looking for and recording information.
  Robots typically start with URLs that seem like a reasonable
  starting spot, such as a URL submitted by a user, a page having
  lots of links, or the top level of a site. A robot accesses the
  initial page and then recursively accesses all pages linked to
  from that page. The robot might also check out all pages that it
  can find on a particular server. After accessing a page, the robot
  works with the search engine to index portions of the page,
  perhaps the title, some or all of the text, specific keywords, or
  other tagged elements.

  One topic that deserves attention, however, is how to prevent
  search engines from indexing individual Web pages or Usenet news
  postings. Conventions exist to keep robots out of specially-marked
  Web pages or news postings, though whether individual robots
  comply to these standards is purely voluntary. So far, mainstream
  searching engines appear to respect these conventions.


**Hey You, Get Out of My Site** -- Using the Robots Exclusion
  Protocol, you can ask robots to ignore Web pages that you don't
  want indexed. For example, you might want to store club meeting
  minutes on the Web without having those minutes show up in search
  engines. You could, of course, set up a password system, but that
  might be a more complicated solution than you wish to implement.
  You might also have a site whose pages change so frequently that
  there's no point in a robot attempting to index them.

  To tell robots to go away, you place a robots.txt file on the
  local root level of a Web site. Using a specific syntax, this file
  tells robots that they should keep out of certain (or all)
  sections of the server. If you want to set up such a file, I
  recommend reading the World Wide Web Robots, Wanderers, and
  Spiders page:

<http://info.webcrawler.com/mak/projects/robots/robots.html>

  As a brief example, though, to ask all robots to keep out of a
  directory called watermelon, your robots.txt file might look like
  this.

 User-agent: *
 Disallow: watermelon/

  If you don't have enough control over your server to set up a
  robots.txt file, you can try adding a META tag to the head section
  of an HTML document. For instance, a tag like this:

<META NAME="ROBOTS" CONTENT="NOINDEX">

  tells robots not to index that particular page. Or, a tag like
  this:

<META NAME="ROBOTS" CONTENT="NOFOLLOW">

  tells robots not to follow links on the page. Support for the META
  tag among robots is more sporadic than the Robots Exclusion
  Protocol, although most of major Web indexes currently support it.
  Information on the robot META tag can be found in the Spidering
  BOF (Birds of a Feather) Report:

<http://www.w3.org/pub/WWW/Search/9605-Indexing-Workshop/
ReportOutcomes/Spidering.txt>


**Private News** -- To keep the fingers of search engines out of
  your Usenet news postings, you can create an "X-no-archive" line
  in of your postings' headers:

X-no-archive: yes

  Although common news clients, such as NewsWatcher, permit you to
  add an X-no-archive line to the headers of your news postings, you
  aren't completely out of luck if your client doesn't permit you to
  do so. At least one engine, Deja News, will ignore your posting if
  you make the following text the first line of text in the body of
  your message:

X-no-archive: yes

  In addition, if you inquire personally, Deja News will remove your
  posts from their archive; to ask, send email to
  <[e-mail]>.


**Assumption of Non-Privacy** -- The source of confusion regarding
  privacy and Internet indexing systems usually stems from the
  assumption (made by most search engines) that _all_ information
  they find is public unless marked otherwise.

  Many Internet veterans have no problem with the search engines'
  assumption that all information is public, since much of the
  material has always been available one way or another. However,
  some new Internet users find the practice startlingly invasive.
  For these Internet users, it's like being told every phone call
  they made during the last year was recorded by a private company,
  who's now giving away those conversations to anyone who asks.

  The long-term memory of these search engines makes the
  ramifications of their behavior larger than ever. Though Digital's
  AltaVista search engine currently only remembers the last few
  months of Usenet, Deja News has archives going back to early 1995,
  and repeatedly claims that it wants to index all the way back to
  Usenet's inception in 1979, where possible. In 1979, how many
  Usenet users could have known about the X-no-archive tag?
  Furthermore, though the robot and archive exclusion standards may
  help keep your material out of major, high-profile indexes, there
  are indexing and archiving systems out there that respect no such
  rules.

  If you're highly concerned about the privacy of your email and
  Usenet postings, check out anonymous remailers and PGP, a
  controversial strong encryption program from Phil Zimmerman. Both
  topics are beyond the scope of this article.

<http://www.well.com/user/abacard/remail.html>
<http://www.io.com/~combs/htmls/crypto.html>
<http://world.std.com/~franl/pgp/>

  If you're not particularly concerned about privacy, still remember
  that your words on the Internet may become immortal - anything you
  write on Usenet will be archived somewhere for eternity, anything
  you publish on the Web will be indexed somewhere. Choose your
  words with care - you may have to stand behind them in a future
  situation that you cannot currently imagine.

  In the future, as privacy becomes a larger issue on the Internet
  horizon, we can probably expect commercial and consumer
  newsreaders and publishing tools to tout "privacy compatibility"
  as a feature. No doubt newsreaders will soon come pre-configured
  to insert X-no-archive headers by default, and Web authoring
  programs will come with preferences to insert robot META tags and
  create robots.txt files automatically. However, these features
  will not alter the fundamental assumptions of Internet indexing
  tools: everything is public.
