Comparison of Video Performance: Microsoft (WMV) , Apple (QT) and Adobe (FLV)


I've had a bad attitude about Flash (Adobe) performance, especially because it doesn't seem to be supported by 64-bit browsers. I've used WMV (Microsoft) as my default video player because I have a windows machine, but I do play games  that use Quicktime (Apple) and Flash (Adobe) so have some experience with all three video players.

This ZD blogpost tests these three players on three machines:
  • Thinkpad X200, a newer Windows machine
  • MacBook Pro 13, a newer Mac
  • Thinkpad T60, an older Windows machine
Here's an excerpt of the results
Average usage rate for Firefox.

Older Thinkpads and MacBooks




Results are fairly close. For newer machines (chart on right), Wave wins by having the lowest percentage CPU usage while Quicktime edges ahead of Wave in remaining battery by 2%. For older machines (chart above), Flash wins in both categories. Quicktime couldn't finish playing the test movie before its battery ran out. 

Adobe has improved Flash a great deal on the Windows platform rendering invalid most of the arguments against it.


The ZD blogpost has good comments on how the various players do or do not support hardware acceleration and the authoring companies' reasons. Might be too geeky for my readers.

Another Giant Leap for Mankind: Synthetic Life Achieved May 20, 2010

J. Craig Venter is not known for charm, but he is undoubtedly one of the most effective scientists of all time, certainly on a par with Isaac Newton, though they both stood on the shoulders of giants. Dr. Venter decoded the human genome; in fact, his own genome. He personally dived the Sargasso Sea to collect hundreds of yet-to-fore unknown organisms and will decode their genomes thereby enriching our knowledge and likely opening new opportunities to enrich our lives.

Do take the time to view Dr. Venter's May 20, 2010, 18:18 minute video explaining the synthetic life project.


So, why haven't the news channels been yammering about it 24/7 like they do for comparatively trivial events? I am unencumbered by any real knowledge so this is pure speculation, but I suggest that the reason for relative disinterest is Dr. Venter has already set up the scaffolding for a commercial venture to exploit this achievement and therefore it is too crass. News people might say that they don't want to be unwitting (or unpaid) advertisers for Dr. Venter. Or maybe the science necessary to explain the project well is too esoteric and the ramifications too mind-boggling for journalists to capture?

I believe that Dr. Venter has already convened a legal entity that has filed patents for his truly innovative processes. I believe that license terms have already been drafted and funding and partnership deals are already underway for joint research, etc. therefore the traditional route for reporting scientific breakthroughs, namely publish in Nature, has already been rejected. So is this a case of a highly structured marketing plan negating the free publicity of a news frenzy?
-----------------------
The Science Channel has already broadcasted two one-hour programs on synthetic life -- one about the project itself and another with bio-ethicist and a priest, hosted by Paula Zahn who did everything she can to sensationalize and sound the alarm about the dangers and threats this discovery may pose.

Feedback from a MicroBiologist
Talked to a microbiologist who I trust today. She said she had read some of the discussion in the science community about Venter's announcement.   They seem to feel that what he and his team did was a proof of concept, putting a puzzle together, not a big step forward. The pro-Venter faction say that people scoffed at the Wright brothers as well.

I can't help thinking that Venter's personality probably did not win him many supporters. Politics pervade all endeavors.

Your Online Reputation

A few weeks ago, I was in a breakfast talk with Zia Yusuf. One of the topics was about online privacy. Zia said that he has given up on trying to maintain any privacy online. I completely understand what he meant, yet I was shocked that he had ‘given up.’ There is a lot of finger pointing about how especially social networks like Linkedin and Facebook betray our privacy, but the information about us that exists online, putting aside things that are uncontrollable by us such as what others say about us or being tagged in a photo or note, is derived from what WE post online about ourselves. So I believe that we are responsible for online content about us. It is up to us to pay attention, be thoughtful, and actively manage our online profiles and reputation.

Most online profile forms ask for a lot of information such as home towns, profession, affiliations such as alma mater, religious practices, volunteer activities, friends and family. People post voluminously about their opinions, products that they use and services that they patronize. Some such information would seem to be harmless. Whether or not I like broccoli won’t seem to have any consequences until the day I bid for a job to market broccoli. Merchandisers are already mining social networks for consumers and advocates ("influencers"). On the other end of the ‘innocuousness’ spectrum is information about our political activities. It is the duty of citizens to be politically engaged, to vote and support candidates, but many decision makers who can significantly affect our lives would penalize those who disagree with their politics. One company offers a tool to monitor employees' activities on social networks! Now, one’s political donations are searchable on the web!

So far, I've only talked about the public web. There is a huge, perhaps even larger body of content on 'private' webs. Most social networks claim that their sites are protected from search spiders, as are many databases such as voter logs, employment databases, criminal records, phone logs... but that information is accessible, ultimately with a court order.

What recourse or remedy do we have, if we’ve already blabbed too much, or the ‘wrong’ stuff about ourselves, online? Some obvious steps are:
  • Do a web search for oneself to see what’s out there.
  • Revise our online profiles
  • Delete material that we no longer want known about us
  • Tell our social media contacts not to tag us
  • Start posting information that we want known about us. There are few and fuzzy grey lines between ‘being positive’ and shameless self-promotion, or uber-political correctness.
More drastic steps to 'fix' over-exposure can be to end affiliations. There are already services to repair and promote one’s online reputation! One example, and I am not at all endorsing this service, is Reputation Defender. I have only read a few pages of their web site but their service indeed resonates. Building a brand online, and everywhere else, is recommended by everyone, including our Moms. One is indeed known more by reputation than by facts.

Use Domain Names for Business and Personal Purposes

I own domain names mainly to promote my business. I have one domain name that is the 'primary,' as well as several others. These are the reasons why I have several domain names:
  • It's worthwhile to own domain names that relate to my business because if someone's search keywords are similar to keywords on my sites, they will still find my primary site. The purpose is to optimize my business web site's search rank, a search engine optimization (SEO) strategy.
  • I own domain names that might be used against my business so that competitors cannot buy those names. For example, if my primary web site were "RevGen Group," I also bought the domain names "RevGen_sucks" and "I_hate_RevGen".
  • I bought several similar or related domain names such as "RevGen_Consulting" and "Web_Marketing_Strategy" for feeder-sites. These clumsy domain names are useful because they are keyword 'farms.' I put content there that are full of key words and phrases that relate to my business, as well as links to my primary site. In-bound links  improve the web site's SEO. These feeder sites increase traffic and improve my main web site's visibility in search results.
  • I redirect all traffic to my business blog to my primary domain name. The benefits of doing this are:
       1. My business blog has an easier to remember URL
       2. A text link on my primary web site to my blog helps visitors get to my blog
       3. I can manage my blog with a blogging applications without having to log into the ISP that hosts my primary web site.

Some families buy domain names for web sites with family news. The global Tseng family has such a web site! (It's in Chinese.) It has news, photos and a forum for members to interact.

Many people are very passionate about certain causes so they buy domain names for a web presence where they promote their causes. A very well-known one is MoveOn.org.

Still others buy domain names from Registrars who are also ISPs because they get a bundled deal where the ISP gives you free email forwarding with your domain name. For example, if I bought the domain "mariatseng" I could have mail addressed to 'maria@mariatseng.com' forwarded to me.

Domain names are very inexpensive and can be very useful.

Digital mobile sensors can save your life, and reduce healthcare costs

This is a very interesting and informative 17-minute video that gives an overview of some of the wireless medical sensing devices that are available to consumers today. The speaker (Eric Topol) gives statistics on chronic diseases (diabetes, heart failure, sleep apnea), and their cost impact in money and quality of life. He cites Wired magazine articles that show the consumer acceptance of continuous monitoring of physiological processes.


Please take the 17 minutes to view this video.
