web site

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?

From a January 13, 2009 email from Michael Chasen to the customers:

Please share any feedback with me directly at a Web site created for just that purpose called Tell Michael Chasen.  I will personally read every message I get, so please let me know what you think.

That page in the email is no longer available.

I guess it was moved in the web site redesign for the launch for Learn 9 (Jan 27), then this page lasted at its original location all of 14 days. The new page is Tell the CEO.

A redirect to get those of us who refer to the emails we have received to the right page would be nice.

Flipping channels, I ran across Deep Impact during a speech given by the president (played by Morgan Freeman).

The black president didn’t amaze me. Hollywood figured out how to portray them a decade before the US figured out how to elect one.

What amazed me is that with all the really cool forward looking technology for the time, instructions for how to communicate the evacuation was sent by fax to news agencies. Yeah, it wasn’t emailed. The White House didn’t post it on a web site. No mention of Facebook. :D

Is NASA powering landing craft with nuclear drives?

At least since this movie aired we have implemented programs to discover both the large and medium objects capable of regional to global catastrophes.

We still need a plan to do something about the ones we anticipate will hit us. Or how about a plan to save our legacies? (The children, art, history)

The claims Blackboard’s Learn 9 provides a Web 2.0 experience has bothered me for a while now. First, it was the drag-n-drop. While cool, that isn’t Web 2.0 in my opinion. A little more on track is the claim:

The all-new Web 2.0 experience in Release 9 makes it easy to meaningfully combine information from different sources. The Challenges Are Real, But So Are the Solutions

Integrating with a social network like Facebook is a start, but again, in my opinion, it still isn’t Web 2.0.

So, what is Web 2.0? I did some digging. I think the Tim O’Reilly approach meets my expectation best. He quotes Eric Schmidt’s ”Don’t fight the Internet.” as well as provide his own more in depth.

Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform. Chief among those rules is this: Build applications that harness network effects to get better the more people use them. (This is what I’ve elsewhere called “harnessing collective intelligence.”) Web 2.0 Compact Definition: Trying Again

Users expect a site on the Internet to meet their needs or they eventually move on to a site which does. There are so many web sites out there providing equivalent features to those commonly found in an LMS. There is the danger of irrelevance. This is why every LMS company or group strives to continually add new features (aka innovating). The bar continually gets raised, so LMS software continually needs to meet this higher standard.

Tim additionally provides some other rules which you can see at the above link.

When an LMS reachs the point where the resources of the Internet helps people learn, then it will be a Web 2.0. As long as an expert or leader imparts knowledge on students, the LMS is still something different than Web 2.0. Sorry…. The irony? This is exactly what Michael Wesch and PLE advocates preach.

Ev said, “To those asking: Site slowness today had nothing to do with @Oprah.” Social networks are amusing and fun at times. I’m just a fan of moderation. Too much of anything will ruin it. Ever since Twitter became the new Golden Tool of PR, I knew it would be a matter of time.

Friends and coworkers bring up Twitter as though they have nothing else to say. Apparently the web sites we use define who we are just like fashion did in the 1980s and 1990s. Well, I am a black teeshirt and shorts guy.

:)

So… I’m spent on < 140 characters.

Update: Maybe not… I’ve culled the list of people I am following from 96 down to 37. Maybe more if I look at it anymore. (Even the 10 most extraordinary tweets couldn’t diswade me.)

This morning there was a flurry of effort to locate an article called “Hacking WebCT.” My coworker was able to locate it. We were disappointed. 

The main points of the article were:

  1. Lazy administrators make compromising user accounts easy.
  2. Lazy instructors make getting questions for assessments easy.

These apply to any LMS. So, here is some advice to counter the issues raised in this article.

 

Accounts

Default passwords are the bane of any system. Make users change them. (Yes, this increases support tickets.) This usually comes about because the administrators did not integrate the LMS authentication with LDAP, Kerberos, or CAS  which allows for central management of accounts. Central management of accounts means fewer accounts are likely to sit around with easily guessed intially imposed credentials. 

Linking many services together also raises the exposure should one account account me compromised. Enforce decently strong passwords. Too strong and frequently changed password will encourage users to employ means of remembering passwords which defeat the point. Passwords probably should not ever be just birthdays.

Not sure what advice to provide about the potential of a student installing a keylogger on a computer in a classroom?

 

Assessment Cheating

A long availability period (like a week) provides opportunities for enterprising students to exploit the issues with passwords to see and research questions in advance. Instead, a quiz with a short availability period like an hour means less time to go look at the other account, record the questions, research them, then go back into the proper account and take the assessment.

Instructors should use custome questions. Students can obtain questionss provided by publishers in ePacks or with textbooks from previous students, the same textbooks the instructor received, or even web sites online which sell the information. 

High stakes testing ensures students are looking to cheat. When the value of questions is high, these easier methods than knowing the material ensures a war between students and instructors over cheating. Of course, lowering the value of the questions increases the workload of the instructor.

The Long Tail claims consumers, given more options, will reflect their widely varied interests. Physical stores cannot fill all of the demand, so bytes stored on disk are the fastest, cheapest method for getting stuff to consumers. We see a mostly example of this shift in the shift to digital music.

Vinyl records were the first physical music media form I used. Later, cassette tapes (1980s) and compact disc (1990s) achieved dominance. In 2001, I started the transition to digital music. There were some stumbles along the way because of technology changes and trusting vendors saying Digital Rights Management is good for consumers. At present, I only listen to digital music when using my own collection.

Digital video seems more complicated. Web sites streaming and on-demand television have the potential to fit the Long Tail model where consumers have access to insanely varied content when they want it. DVRs neither fix the when (just shift the airing to another time) or the insanely varied content. Movie rental distributors like Blockbuster and Netflix are moving toward distributing digital movies and TV shows in setups similar to on-demand. Nothing has even come close to winning.

Digital books may yet get some traction. Computers screens cause eye strain. Laptops don’t feel like a book. PDAs, Blackberrys, and other handhelds with small screens require a ton of scrolling. A recent solution to this is “epaper” which doesn’t constantly refresh. The Amazon Kindle and Sony Reader are the biggest players. (The Long Tail is not available for the Kindle but is for the Reader. WTH?)

Remaining issues for me:

  1. Ownership is dying.
    • I really like the idea of playing music on my iPod or from CDs. I play DVDs on my computer because I can’t play my DVR stuff in a hotel. So streaming and on-demand only solutions bother me as long-term solutions. If it is easy for distributors to store it because it is just bytes, then it is easy for me to do so as well.
    • I have books from 20 years ago I can still read. Technology changes too much to depend on something I buy today working tomorrow. So maybe “renting” is a way better approach for digital media?
  2. The black markets for music and movies prove consumers want everything any time. Companies must embrace consumer demand and make it easier for consumers or suffer. I think companies changing to accommodate consumer demand is the only reason the music companies have survived. Litigation cannot solve it.
  3. Hardware investment gets expensive every few years.

My solution? Wait and see.

Digital Legacy

A book on time management in talking about long-term goal planning suggests we define the legacy we wish to leave. Coming from academia, I typically think of a legacy as a name on a building, an applicant with an alum for a parent, or a scholarship. However, the artifacts left behind by previous cultures are also a legacy.

Our digital footprints both could be part of this legacy or easily lost. I lean toward all this data we spew about the Internet will be lost eventually. I have seen floppy disks and hard drives die, taking with them the only copy of critical data. I have seen companies report their hard drives stolen from their machines in co-location as why customers lost their data. I have seen companies close web sites because they ran out of money. Let’s not forget natural disasters like earthquakes and floods.

So we keep backups.

Who will preserve these backups once we are gone? Are you able to read the data from computers 40 years ago? Maybe we’ll be better about being able to read the data from past when we reach 40 years into the future?

Not likely.

American politics frustrates me. Little of it is genuine. People are being tricked into believing obvious lies. Positions are veiled in marketing speak to make them sound better than the reality. Maybe there is an honest candidate? I just don’t have faith in the integrity in the American political system. In any case, I have already voted. I recommend that if you can, then get it done ASAP and prior to the actual election day.

Apparently there are lots of car accidents on Election Day? I’ll hopefully be teleworking that day.

I turned down an offer to work a web site called Real World Painting. The kid doing the web site let it get suspended (back up now). So the owner wanted my advice. He really needs the most help with search engine optimization. He’s interested in reading up on it. Anyone have suggestions?

A friend has turned up with lymphoma. So I will probably set up a web site to accept donations to help this family with the expenses.

Been talking with Mom about the economy. I did a quick calculation. Add $700 billion to the $10.3 trillion national debt to get $11 trillion. The employed U.S. work force is about 145,255,000. That puts the burden of this debt at 75,728.89 per worker. Add in those on employment or not in the labor force to get 234 million people. We share a $46,936.33 burden. Last I did this calculation it was only around $30 thousand.

That is enough for now.

A few weeks ago, NPR aired a piece where McCain and Obama advisors about technology expressed the policy intentions of each candidate. Also, Obama was described as being a Crackberry addict. McCain was described as personally being technology illiterate, but he looked forward to someone showing him some web sites.

So now, Google purports to allow you to “track the news sites and blogs Barack Obama and John McCain read”. If McCain doesn’t use the Internet (including the World Wide Web), then how is he reading these news sites and blogs? Someone prints them out for him?
