Imagine if some advanced species decided to interfere with human reproduction, selecting
the most grossly fat males as the only suitable mates then later forbidding copulation altogether, managing all
reproduction with artificial insemination. Might we humans harbour a little resentment? It would be hypocritical of
us to complain since this is what we have done to pigs and cattle.

local browsing: Two ways of browsing HTML from local hard disk. The pitfalls.
double clicking: The problems with double clicking mice and various solutions.
digest: Various ways to compute Digests and hash functions. How to estimate the number of expected collisions.
mouse: I have updated the entry on mice, adding new sections.
indexes: I just noticed that the indexes were malformed. I did not notice the bug until now. I have corrected the problem. I have added a programming tip learned from analysing my error. I have been converting the website to HTML5. This required changes to the various programs I use to analyse and generate the website HTML.
batteries: All about batteries, the various types, polarity, recharging, testing, cleaning and corrosion
unlimited strength encryption: How remove the limit in Java on encryption strength. Without this fix, SSL is limited to a paltry 40 bit encryption.
acronyms: Acronyms now appear in a deep blue-green font throughout the site. If you hover your mouse over them, they will tell you what they stand for. In addition, the first time they are used on any given web page, they are expanded to see without hovering.
ClusterMaps: Every web page now tracks and displays a unique visitors cumulative count. If you click the icon, you can see where visitors are coming from. It will take a while to accumulate enough data to make the maps interesting.
JDK 1.8.0_05: Oracle has released a new JDK — version 1.8.0_05. At the same time, they upgraded version 1.7.0_45 to 1.7.0_55.
ClusterMaps: A counter you can put on your webpages that tracks hits to your site and where they came from.
Chrome: I have been experimenting with the Google Chrome browser. I have been tweaking the HTML/CSS markup on the mindprod website to make it render better under Chrome. It is quite a nice browser, fast, bug free, polished… I have avoided it in past because it stubbornly refuses to support an edit source button to let me use my own editor to edit web pages.
HTML5: The conversion of the website to HTML5 is nearing completion. There are only 5 (rather large) documents left to be converted. You probably will not notice anything other than slightly more consistent layout.
Applets: I have updated the entry on Applets to include problems with AppletContext.getApplets() and HTML5 <OBJECT tags
Hybrids: How to make your Applets and JApplets work from the comand line like ordinary applications.

schema.org: A way of marking up your HTML with tags to identify what sort of data it represents to help search engines and screen scrapers.
Timestamping: Timestamping jars so that they will continue to work after the certificate expires.
server farm: Difference between a server farm and a cloud.
Biorhythms: The Biorythm calculator is now working again. Oracle now insists tha programs using getResource be signed, but they did not tell me or give an error message as to the problem.
The Replicator: Oracle changed Java in a way that made the Replicator stop working. I have implemented a work-around. It should be working again.
HTML 5: The conversion of the Canadian Mind Products website to HTML 5 has begun. If you have trouble viewing the site, use a newer browser that has HTML5 support. The pages that have been converted to HTML 5 begin <!DOCTYPE HTML>. Everything has been converted except the Java glossary proper.

Bat/btm Properties: Options, Layout, Font and Colors properties an bat and btm batch files
Long Outage: About 2014-03-24 2AM there was a massive power surge in the building containing the servers that host mindprod.com. Computers and UPSes were fried. It has taken a while to get back on line.
JDK 1.8: JDK 1.8 has been released. I have converted the entire website and all utilities to use it. I have also migrated all utilities from 1.1..1.6 to 1.7+
The following essays and entries recently changed:
Dyson Vacuum Cleaner: Endorsement for Dyson DC51 vacuum cleaner, including an instruction manual to replace the one that does not come with it and is not posted on the Dyson website that explains what all its buttons are for.
I am in a bit of a pickle. My HIV (Human Imumuno-deficiency Virus) drugs have stopped working. My personal load of
viruses over the years have done an astounding job of evolving immunity to all the HIV
drugs that I can tolerate. A new drug was supposed to be
released 2013-03, but it still has not appeared. My energy level is dropping to a
distressing degree. I find I have to work myself up mentally with adrenalin to get anything done.

I accidentally discovered that avoiding wheat cleared up my problems with non-stop nausea and digestive
tract distress. Unfortunately, I just love baked goods, and find the wheat/gluten-free replacements insipid.
Further, getting serious about avoiding sugar in any form, especially fruit juice, is improving my energy
level. Last revised/verified: 2012-02-27

On 2013-01-19 on the CBC (Canadian Broadcasting Corporation)
radio show The House Lt.-Gen. (Retired) Andrew Leslie pointed out that the Harper government spends
$3.25 billion a year on the military. He also pointed out that the yearly budget for
consultants and professional services has increased by $450 million since
2010. Further, money spend on the army itself, such has training has dropped 22%, even after you discount the drop from the wind-down of the Afghan war.
Leslie is concerned about impaired readiness. I am concerned about corruption. The military is the ideal place
to hide kickbacks to political donors. The military is not required have to anything to show for its expenditures,
such a bridge or sewer system. Further, the government can invoke secrecy at any time to block investigation of its
criminal activity. We have seen how when the Americans over-used consultants in Iraq and Afghanistan, it
immediately lead to monumental corruption.
