DDoS of Social Media

August 8, 2009 in Interweb, Social, Social / IM / Chat by Ezra S F | 1 comment

Twitter, Facebook, LiveJournal and other sites all admitted to suffering from a DDoS attack. It seem to me the purpose of a Denial-of-Service attack (DoS) against a web site is to flood it with so much traffic the site becomes unusable. The DDoS is where multiple other computers are coordinated into launching the attack.

All three of the above mentioned sites have had recent issues keeping up with growing usage. The USA inauguration and Iran demonstrations peaked traffic so much the sites seemed like they suffered from a DoS. Already at the edge, an attack tipped the barely making it social media sites over it. Some users abandon them for less popular (so more stable sites). Those who stick around suffer from learned helplessness.

Causing all this hullabaloo over a single user seems odd to me. I don’t speak Russian, so I don’t know if this guy from Georgia (the country) deserved it. Also, it is almost the one year anniversary since Russia invaded Georgia. During the invasion, DDoS attacks disabled Georgian web sites. So, maybe this is to show Georgia the Russians are still capable of causing problems? This is why security evangelists want us to be able to deal with threats.

Various computer viruses over the years have turned millions of computers into zombies for botnets. So… If you are upset about your favorite social media site getting taken down, then maybe you should act on ensuring your computer and others in your social network were not enlisted into a botnet?

Turnitin.com

August 6, 2009 in University by Ezra S F | No comments

I’m surprised I have not blogged here about the student lawsuit against Turnitin.com? An anti-plagiarism service, Turnitin has students or faculty members upload papers into the database. By comparing new papers to the database, it gives ratings as to whether it is likely a student plagiarized.

Now the search goes out for any student who has a paper that’s being held by TurnItIn that they did not upload themselves. Students Settle with TurnItIn

In theory I could be someone in this situation. Back in 2005, a coworker asked my mother if someone by my name was related to her. This coworker was taking some classes at the university I attended. Turnitin had threw up a cautionary flag on the Originality Report because it was somewhat similar to something with my name on it. The problem is this product came into use at the university after the time I was a student. So I never submitted anything to it. The department from which I got my degree kept a copy of my papers (many submitted by email) and used this product at the time.

Another possibility is this tidbit about the product: Over 11 Billion Web Pages Crawled & Archived. I was actively blogging before and at the time of the incident. Assuming it could identify my name out of all that content, this match could have come from my blogging.

When I contacted Turnitin about this back in 2005, they told me I would have to remove my paper. I re-explained that I didn’t submit the paper. So Turnitin explained that whoever did put the paper in the system would have to remove it. The guy acknowledged the difficulty of the situation in identifying who posted it.

Dangers of Serotonin

July 16, 2009 in Psychology by Ezra S F | No comments

He’s associated damage to the temporal lobe with psychopathic killers. The epigenetic effects, brain damage, and environments appears to be an MAOA variant on the X chromosome with experiencing violence around 3 years old.

Males only get the X from their mother. Men are much more likely. Girls get one X from mother and one from father which dilutes. Bathing the brain in serotonin too early makes the brain insensitive to the calming serotonin later.

Interesting.

I’m blogging this.

July 5, 2009 in Athens GA, Photography by Ezra S F | 3 comments

Elizabeth For about eight months I have participated in a group called the Brunch Bunch here in Athens. We get together to eat and talk. Many conversations drift into the nerdy (my forté?). The locations vary so I have gotten to try new (to me) restaurants. Elizabeth (pictured right) vouched that I am a great guy. Well, these are great people.
:)

Elizabeth also brought a friend of hers from out of town, Claudia. Claudia, smartly has a newer version of my Canon Rebel. I have the XT. She has the XSi (two models newer). The newest is the T1i.

Downtown Athens is a great place to shoot photos. So, we walked around for an hour or so looking in stores to get out of the heat. This is the hat Elizabeth bought from Helix who also had some cool stone candle holders. Native American Gallery had some interesting petroglyph jewelry and gray flower pottery. I’ve got some ideas for gifts to give for upcoming birthdays, holidays, etc.

One of the employees at Helix and Claudia both asked if I had a blog. I’m sure it was because of my shirt! I only admitted to this one and blogging about Blackboard. Though, I guess I have diversified somewhat here. I probably should blog more about local stuff as well. That would mean getting out more as well.

I'm blogging this.For years, I have been collecting teeshirts from thinkgeek.com. At present the collection consists of:

Some others are on my wishlist. I do have some shirts from other places. By far the most popular is the xkcd sudo comic. I’ve added a few others from xkcd to my wishlist as well.

Voting Rights Act

June 25, 2009 in Gov't / Law / Politics by Ezra S F | No comments

The Voting Rights Act of 1965 protects people from malicious actions by state and local governments to prevent people from voting. Yes, we have a president of African-American descent. Yes, the United States Supreme Court took no action. However, the majority opinion statement that, “We are a very different nation,” suggests it could be repealed. The argument against maintaining the law seems to be since governments are behaving now no law is needed.

Are they? The DOJ disallowed a Georgia program to cull voters from the databases who might not be citizens. This strikes me as just like the Florida Central Voter File program in 1998-2006 to cull ex-felons from voter lists. Since they just used names, it was highly inaccurate and wrongly disenfranchised thousands in 2000… in Florida… the state which made international headlines as the place unable to count ballots. When Congress renewed it in 2006, “It held extensive hearings and produced voluminous evidence that minority voters continue to face significant obstacles.” [NYT] I may have to go looking for this in the Congressional Record.

With the protests happening in Iran right now about voter irregularities, is this the time to repeal one of the few deterrents against future abuses to erode the significant improvements over the past 40 years?

Cosmological Constants

June 15, 2009 in Science by Ezra S F | No comments

Guess I am pretty dense. As many books and TV shows as I have read or seen about Einstein, physics, and cosmology, I just understood something for the first time since it was extremely plainly laid out for me. An ever expanding universe requires one or more forces to push matter further apart: cosmological constant. Forces attract or repel. Gravity attracts matter. Yet there is something, still unknown, repelling matter.

2nd Blackboard Blog

June 11, 2009 in Blackboard Vista, Corporations by Ezra S F | No comments

A blog without comments to me isn’t a blog. Blog posts are about stimulating discussion, so the comments are most important feature. Content without feedback is a publicity or news story not a blog. So Blackboard Blogs at educateinnovate.com isn’t really a blog.

Steve Feldman, Bb performance engineer, had the first Blackboard Inc blog with Seven Seconds. He mysteriously stopped last fall. :(

Ray Henderson, new Bb President for Learn, has a blog. Read this introduction post. He specifically wants discussion and dialog. Someone at Blackboard who understands The Cluetrain Manifesto? I am hopeful this is a sign of positive change.

Loving Day

June 7, 2009 in Movies / Films / TV, Race / Racism by Ezra S F | No comments

guess_whos_coming_to_dinnerLast year, I blogged about Loving Day. To recap:

Loving Day is an educational community project. The name comes from Loving v. Virginia (1967), the landmark Supreme Court decision that legalized interracial marriage in the United States. Loving Day celebrations commemorate the anniversary of the Loving decision every year on or around June 12th.

There is a list of Loving Day celebrations around the world. The Georgia one happened last month? Oh, well.

Do you have any plans? Maybe I can find a copy of Guess Who’s Coming to Dinner by then?

Feedback Loops

May 17, 2009 in Movies / Films / TV by Ezra S F | No comments

Remakes don’t scare me. Some are good. Some are bad. 

The thing to remember is, “Its just a movie.” The world won’t end over a poor movie. There’s always another one in a few weeks to either like or hate. If it stands up to the test of time, then you’ll buy the Blue-ray and next three formats over the next 30 years. If not, then just ignore it ever existed… Much like I’ve done with Superman III, Superman IV, Star Trek The Final Frontier, and hundreds of other movies.

Getting worked up over change? Not worth it.

Quibblers would have kept “Star Trek” more like its old self. Quibblers inhibit revolution. Quibblers would deny the basic law of forward motion in pop culture:

If you love something, they will remake it.

But if you really love it, you will set it free, and let them.

The Trouble With Quibbles

Film makers should keep in mind, the types of people involved in  fads: connectors, mavens, salesperson. Fans are mavens. People are going to trust the opinion of these fans. So if the fans’ concerns are just a few quibbles but still an endorsement, then the general public will flock to the movie. If these quibbles amount to wide rejection of the movie by the existing fans, then the general public will mostly stay away from it.

Quibbles are not really the issue. Endorsements are. 

I think you missed that there is a life-cycle to most such endeavors, and feedback is very useful at specific times, and disruptive (in a bad way) at others.

So, the problem with “fan feedback” non-stop is that they tend to fall into a mob mentality, off being “trolls” about any innovation. But, that said, remember that early forms of the Batman movie with the Heath L Joker was shown to fans (at a Comic Con) to get feedback on the style and whether too over the top. The feedback was used to find the balance and deal with the nature of the ending. Fans were given leaks and teasers (semi-trailers) along the way as well, but the mob rule was not allowed not hound the people making it.

That said, what makes a movie work or not is very different from what made its source material work. The reason the Spiderman movies worked for a large audience who knew nothing about the comics had a lot to do with the simpler nature of the comics. Batman has always been more complex in the psychology of its heroes and villains, as much by what does not happen as what does. Watchman is trickier given its narrative model and how much it connected with its time (Cold War, etc).

— PaulK
The Downside of Feedback

Design by committee sucks. So fans should not take over the process. However, total rejection of fan criticisms probably will result in rejection by the fans and slow sales.

Smart Boys

April 23, 2009 in Psychology, Science by Ezra S F | No comments

George and I talked about this some last night.

Nature vs Nurture… I tend to think of both as bottlenecks for human development. The debate about which does more to me makes as much sense as debating which is better for a web application: Apache or MySQL? Both are involved and affect the end results. The debate should be about how to leverage the synergy of both, but that is another blog post.

We humans have 46 chromosomes. 23 from each parent which come in pairs. Males have an XY pair. Females have an XX pair. Brain Rules was the first I’ve read that ~1500 brain-related genes are on the X and ~100 on the Y (and losing ~5 every million years). So the X chromosome is quite important for determining brain development.

For boys, the one X they have comes from the mother. Girls inherit an X chromosome from both her mother or father. To set up the strong potential of great genes for boys, look to women who are really intelligent. That tells you there is a 50% shot for the boy to get a good X. If both of the woman’s parents are intellectuals, even better.

Be smart about it though… Don’t make an IQ score for the parents part of a prenuptual agreement.

My mother has occasionally said things I enjoy remind her of her father. That’s a biased sample. 
:)
