start the Replicator Click the dark blue WebStart button to the left to start the Replicator and download the complete mindprod.com website, or update your local downloaded copy. To learn in detail how the Replicator works, read the manual.

If, replicator, the above The Replicator signed Java Web Start application does not work…

  2. This signed Java Web Start application needs Java 1.6 or later, version 1.6.0_07 recommended and a recent browser.
  3. You should see an Java Web Start above looking much like the screenshot. If you don’t, the following should help you get it working:
  4. If you are using Microsoft Internet Explorer, try another browser. Seriously. Microsoft has taken great pains, over and over, to screw up Java and every other multi-platform standardisation.
  5. If you are using Internet Explorer 7 or 8, you must allow blocked content permission for Active X to run. This also gives permission to Java to run. Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java. Don’t put up with it! Use a different browser.
  6. For this Java Web Start to work, you must click grant/accept to give it permission to write the downloaded files to your hard disk.
  7. Optionally, you may permanently install the Canadian Mind Products code-signing certificate so you don’t have to grant each time.
  8. If the above Java Web Start appears to freeze-up, click Alt-Esc repeatedly to check for any buried permission dialog box.
  9. If you have certificate troubles, check the installed certificates and remove or update any obsolete or suspected defective certificates. The only certificate used by this program is mindprodcert2008dsa.
  10. Even if JWS (Java Web Start) complains that the certificate used to sign this application is “invalid”, please click grant/accept anyway.
  11. If the above Java Web Start does not work, or if it fails to automatically install the latest versions, try running:
    javaws.exe -viewer
    on the command line, then click show resources and delete any of the resources that you want refreshed, and try launching the application again.
  12. If the above Java Web Start does not work, or if it fails to automatically install the latest versions, try uninstalling the JWS application in the control panel or uninstall it with:
    javaws.exe -viewer
    on the command line, and try launching the application again.
  13. If reinstalling does not work, especially if JWS appears to be using an obsolete *.jnlp file stuck in cache, try bulk uninstalling all JWS apps with:
    javaws.exe -uninstall
    on the command line, and try launching the application again.
  14. If the error message says “program not found” the problem is likely a damaged association between *.jnlp files and the javaws.exe program. To learn how to repair the association, click the Repair button below.
  15. For Firefox, select open with: Java(TM) web start launcher.
  16. To ensure your Java is up to date, check with Wassup. First, download it and run it as an application independent of your browser, then run it online as an Applet to add the complication of your browser.
  17. If the above Java Web Start does not work, check the Java console for error messages.
  18. If the above Java Web Start does not work, you might have better luck with the downloadable version.
  19. If you still can’t get the program working click HELP for more detail.
  20. If you can’t get the above Java Web Start working after trying the advice above and from the HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email atemail Roedy Green.

You can safely abort at any time. The Replicator will pick up where you left off the next time you download. If the Replicator fails, try again in half an hour or so. There may have been a glitch in uploading the files.

To read more about how the Replicator works, read the Replicator Manual.

The download covers definitions of Java terminology, essays on various Java related topics and pointers to where you can get more information about Java related problems. It also covers the entire mindprod.com website which discusses political, environmental and religious issues. It includes the gay glossary, the Computer Hardware Buyers’ Glossary, all the sound and image files.

I update the website many times a day and post the changes to the Replicator. You can stay as up to date as you want. You can run the Replicator to update your local mirror copy as frequently or as infrequently as you like. Whenever you run the Replicator, you will get just the net changes since your last visit.

You must run the Replicator every time you want to get the recent updates. It will not automatically schedule itself. After the first time, it will be very quick unless there has been a massive update to all the headers and footers.

Google Desktop will then let you find anything in the local mirror with indexes that are only seconds out of date.

The Replicator downloads the website is in ~1 MB zipped chunks, and automatically unpacks and decompresses them. On subsequent visits, The Replicator automatically downloads just new zips containing files that have net changed since your last visit.

To disable the ads during off-line browsing, turn off JavaScript.

If you have trouble with the download button, try starting Java Web Start manually with:

javaws.exe http://mindprod.com/webstart/replicator.jnlp

If the Replicator just sits there and does nothing, and you are using Version 1.5.0 (build 1.5.0_07-b03). Fedora Core 5 Linux, if you upgrade to JDK 1.6 it will work.

If you have trouble, email me atemail feedback to Roedy Green or Canadian Mind Productsor arrange a phone call and I will talk you through the setup. This software has been working fine for years.

It will take a long time (still under 10 minutes for ADSL) for your first download (~85 MB broken into 1 MB pieces) but subsequent ones should be rapid.

You can safely abort at any time. The Replicator will automatically pick up where you left off the next time you download.

Why download with the Replicator instead of browse online?

  1. If mindprod.com goes down temporarily or permanently, you will still have a copy.
  2. You can browse your local copy more quickly than the web copy. You will find the Google AdSense ads will drive you nuts off-line trying to fetch an ad from the the unreachable Google server. I have not yet figured out how to suppress the ads automatically when you are viewing off-line. However, you can suppress them by turning off JavaScript support in your browser. You can turn off the ads while you are online this way too.
  3. You can use your local search tools to find things.
  4. You are providing yet another level of backup to foil those who would destroy the mindprod.com site. Because the material is constantly changing, and won’t stay up to date, please don’t repost pages from my website unless my site disappears completely. The web is littered with out-of-date copies of my material that people stumble on. If you want to host a complete mirror site that I will keep up to the minute, please send me an email at email feedback to Roedy Green or Canadian Mind Products so we can work out the details.
  5. With the Replicator, your local copy can now be just as up-to-date at the uncompressed website HTML with very little overhead.

See the manual to learn how the Replicator works and how you might use it for your own websites or bulk file distribution problems.

To get best performance from the Replicator, you should tweak/tune/configure/adjust your TCP/IP downloading. This will speed up all your internet connections and downloads, not just the Replicator, perhaps by as much as 100 times. Try any or all of these tuning tools to see which works best for you: TCP Optimizer, TweakMaster or TweakDUN.

Beware. The Google web accelerator proxy drastically slows down Java Web start unless you configure jawaws.exe to use a direct network connection.

Because of a limit inherited from MSDOS, and the PKZIP format that the Replicator uses to distribute files, the reconstituted files will have timestamps accurate only to within 2 seconds of the original. The timestamps reflect local time on the source, not UTC time. This will cause no problems with the mindprod.com files since the timestamps are only used to give you an idea of when a file was last changed.
