Hello,

Blogs are a familiar feature on the internet - where users post content in an accumulating manner, with comments, and search options, etc. They facilitate expression and exploration, and via attached comments, also debate and synthesis.


Reading and
Navigating Blogs

Our blogs are quite powerful. Each writer can post, as is typically the case. Sustainers who have the option can also post, however. All Blogs appear in the blog system, and sometimes also in content boxes the top page of ZNet - and always via the left menu of the top page - and can be found via searches, etc.

Commenting on blogs follows the blogs, attached at the bottom, and blog comments, like all others, are also visible in many places that show comments including in the forum system. In addition, the entire blog system gathers content for everyone - but one can look at the accumulating content in many ways.

  • For example one can look at one writer's efforts - so one is seeing what is effectively a blog system for that one writer, or Sustainer.
  • One can also look at the content by topic, seeing blogs that are tagged as being about a certain topic - or place, as well. Thus, when doing that, it is a blog system about a topic, or a place, with many contributors.
  • One can look at only writer blogs, or only sustainer blogs, as well.
  • One can look at blogs for particular Groups, too.

All this is easily done using the left menu. Searches allow even more variables and refinements.


Creating Blog Posts

If you are a Sustainer with permission, and are logged in, you will see a link in the left menu for you to post a blog - and you can use that to post one, and then tag it various ways (such as with a topic or place, or a group tag), and once you do, it is in the system with you as the author.

You can also use the console button to the left to post a blog - anytime and from anywhere in the site, as long as you are logged in.

Meanwhile, enjoy the blogs - and, by the way, if you are a Free Member or a Sustainer with a ZSpace page, of course you can put one or more content boxes on it, pulling blog links of any sort you may want to filter for, for example, by you or by your friends or by others - and by topic, about places, for groups, etc.

Super Bowl XLV and Texas Power Outages

By Michael McGehee at Feb 02, 2011

People throughout the state of Texas are experiencing periodical rolling blackouts. Oncor, the largest energy provider in Texas, has been telling the local television stations that due to the massive winter storm that has hit much of the country this past few days there is not enough energy to meet everyone’s needs. But it looks like the blackouts have more to do with ensuring there is enough electricity to satisfy Super Bowl XLV.

 

Two people embrace, right, as another walks by ...I woke up shortly after our first blackout and the temperature inside the house was climbing up from 66°. I woke my wife up saying, “The power was out.” Yesterday we stayed home because of the winter storm. Amy tried going in to work but was unable to so she has been working from home and since the girl’s school have closed I have had to stay home to watch them. We turned on the television this morning and that’s when we started hearing about the rolling blackouts. An Oncor representative told channel 8 that the blackouts would be no more than 15 to 20 minutes. Shortly after saying this, the news station reported that they have taken many calls from residents across that Metroplex that this isn’t true. Many have been without electricity for one to two hours or more. Families huddled together under several layers of blankets trying to stay warm. After incidents like this was reported Oncor said this is probably due to other power issues and provided a phone number for people to call to report other issues. It wasn’t long after this that channel 8 began reporting complaints from residents that these extended power outages are more wide spread and that the telephone number provided gives folks the run around with no ability to report their problems. They say they are unable to reach a live person. I was pleased to hear the news anchors call Oncor out by saying they “need to step up.”

 

With temperatures currently—I am writing this around 10:30 am—around 12° and a wind chill below zero, and with roads unsafe to use, and many workers like myself having to stay in, and most schools and daycares closed families are finding themselves freezing in their own homes.

 

My wife’s grandmother just recently experienced one of these blackouts around 8:00 am (this was her second blackout). It triggered her alarm system, which went off and when the Arlington police officer responded he informed her that these blackouts are to preserve enough energy to satisfy the week long events going on for this weekend’s Super Bowl at Cowboys Stadium/Jerry World in Arlington, Texas. ESPN is reporting live from Sundance Square in Fort Worth. My wife works in downtown Fort Worth and she has told me about how crazy it is downtown. The Super Bowl . . .

 

. . . I hate to interrupt my own blog post but it’s 11:07 am and the power just went out. We are at my wife’s grandmothers. We left out home because the power went out again, and now the power is out here, which had a power outage only three hours ago.

 

Pittsburgh Steelers Dennis Dixon records teammate ...Anyway, the Super Bowl has taken over not only the Metroplex but the entire state. So far the local news stations are not reporting that homes and business going without electricity—which is necessary to have heat—so as not to interrupt the Super Bowl by the inconveniences the rest of us are enduring. All week long there are events going on at Jerry World. Think about all the energy that is needed to accomodate this and the other events throughout the Metroplex. One estimate is that all the events from the Dallas Convention Center to the media events at Cowboys Stadium to hotel costs and transportation (though I am not sure if it includes the ESPN setup in downtown Fort Worth) will be the equivalent of what one home could use for 1,500 years, or 1,500 homes for a year!

 

It seems the NFL and Jerry Jones has said about Texans: “Let them eat cake!”

 

If you’re a Texan and are reading this then you are lucky to have electricity right now. We need to do what we can to get the media to report that we are going without to accommodate the energy-slurping going on called Super Bowl XLV.

 

Since the power is out here we are going to try our luck at my wife’s mom’s home. She is working remote and finding it hard to get work done with the power outages. Hopefully I can publish this when we get there.

 

Trying to stay warm in North Texas,

Michael McGehee

 

PS: If it gets bad enough perhaps I will take my family to Jerry World since apparently they are not experiencing the same problems . . .

 

PS: It’s 11:41 and the electricity has come back on. My wife went to her mothers but the kids and I stayed at her grandmothers. I am going to publish this now.

PS: I just found this article on WFAA, channel 8: Planned outages won't affect site of Super Bowl

Decaying Network

By Andrews, John at Feb 03, 2011 14:51 PM

Sorry to hear about the bad weather, I would not have expected that in Texas! Everything grinds to a halt pretty quickly here in London once the snow starts falling.

It sounds to me that you are suffering from a decaying electrical distribution system. Under normal conditions there is probably 10% spare capacity in the network but when it gets really cold more electrical power is needed for heating purposes. The underground cable and overhead line infrastructure is probably +50 years old in places - old, rotten cables utilising oil or gas as insulation. The cables cope with normal current flow but start to fault when carrying higher currents as, over the years, the gas or oil has leaked from the cables. Old overhead lines are notoriously prone to mechanical failure as a result of carrying the additional weight of snow and ice. To save costs, the utility company will have cut back on maintenance and renewal as they impact on profit margins. Why renew for the future when we only care about now?

Such faults in the distribution system can lead to a domino effect whereby a primary substation overloads and shuts down which, in turn, overloads other primary substations connected to the shut-down sub and the next thing you know you have a cascading fault coursing through the state and into the adjacent states. This happened on the east coast of Canada and the US back in 2003 (I had just entered Toronto Airport when all the lights went out!). 

To put it crudely, your utility company will be crapping themselves at this moment in time - freak weather conditions, a shot distribution system and the Super Bowl coming up. To avoid the cascading fault syndrome, I reckon they are load shedding as the demand peaks and non-essential consumers are being cut off for shortish periods of time. A major cascading fault could take weeks or months to put right as each substation has to be disconnected from the network / grid and re-energised in 'island mode' and these 'islands' are slowly reintegrated with the transmission and distribution networks.

Sorry to be a purveyor of doom and gloom. I wish I could say everything would be okay but I cannot as the cables, lines and substations will not automatically replace themselves and the utilities do not seem to be too keen on doing it. Methinks things can only get worse.

Best wishes
