This article talks about the two criteria a technology buyer can apply to determine if the 'open standard' they are intended to rely on is really open at all. Those criteria are – licensing and change control.
Licensing controls who gets to implement the standard and what price they have to pay to do it. Open standards are licensed under 'royalty free' terms which means that anyone can implement the standard any time they want without having to pay any money or ask anyone's permission. Closed standards are almost universally RAND or RAND-Z based.
Change control identifies who has the right to say what the standard is and change it as time goes on. Open standards are owned by open standards organizations which have reasonably open membership and voting procedures to approve standards that can not be hijacked by a small group of people/companies. Closed standards either haven't been submitted to any open standards organization, have been submitted under dubious circumstances or have been submitted to pseudo-open standards organizations created to provide the veneer of openness.
Of these two criteria licensing is the most critical. If you check nothing else, check the license because if it isn't royalty free it isn't open.

My job requires me to give endless numbers of presentations to everyone from highly technical audiences to just general folks. Over the years I have developed a few heuristics that I share in my presentation Tips on Presentations [PDF] [PPT].
I want to thank the folks at http://www.cs.kuleuven.ac.be/system/services/e-mail/spam.shtml for reminding me of a very old trick. In most mail systems if you send yourself mail of the form firstname.lastname@example.org it will be delivered to email@example.com. This is great for signing up to e-mail lists (that you honestly want to get mail from) because you can trivially filter on the + and you can keep track of which e-mail list is sharing your name with whom. This is just a rehash of the old 'fake middle name' trick that was used to track snail mail mailing lists. It's the really obvious ideas that are the most useful. In my case I own my own domain so I can actually just use alternate e-mail address (e.g. firstname.lastname@example.org).
I also decided to get a mail filter to check for spam. I literally receive over 50 pieces of spam a day. That's what I get for having a 10 year old e-mail address. The winner was Mail Washer ($20 donation). It has a nice interface, automatically hooks into the major spam black lists, the heuristics seem to work well, the mail preview works great and it's free. The only downside is that it only supports POP. This is probably a show stopper for most folks but in my case it's fine. BTW honorable mentions go to Spam Detective,SpamEater Pro and PocoMail.
This web page is available via http://www.goland.geek. IANA's incompetence and bad faith has reached legendary status in the Internet community and we desperately need an alternative. I don't claim that OpenNic has the solution but we have to do something. I now point my PC's DNS resolution to http://www.opennic.unrated.net/personal.html. Yes, this has obvious privacy ramifications but I'm willing to live with it. Thanks to Simkin for hosting my .geek DNS record.
How can something be a de jure standard and still not be open and freely available? When it's license isn't Royalty Free/Reciprocal.
If I were XML king for a day and could make any change I wanted to XML it would be to add length encoding. Length encoding would provide an order of magnitude better performance in handling XML messages, make XML proxies practical and finally rid us of MIME.
