Que sera, sera, whatever will be, will be, but first I need more coffee.

Social Media

I really don’t know what the term means, but I do know this. It is a mistake to have your friends using all of the same social media that you do. I’ve offended someone on one of them, but I can’t go to the other social media to vent because they are on it as well. Fortunately, they are not here. I should probably apologize, but what I posted wasn’t that bad… in the grand scheme of things.

I recently posted on Facebook about it’s fine grain control of what your FB friends see and what you see. I hide most people from my status feed, because for the most part I don’t know them or haven’t had that much contact with them online. I’ve also created groups that only certain people can see what I post.  If I post something a little off color, I don’t want my father-in-law seeing it. Although I mostly group people into ultraconservative, conservative, and normal. I’ll occasionally make political posts to the conservative group. Normal sees everything.

I know that I’ve offended my conservative friends from time to time (and deliberately so). What I don’t understand is why they either don’t unfriend on Facebook me and maintain contact via email or hide me from their feed.  I’ve even explained in so many words how they can control what they see and who sees what they post.

Cabin in the Woods

 Before Facebook and Twitter there was LiveJournal. I rarely used it. And still I don’t post much here. It doesn’t feel as active a community as those others. And that’s the way I like it. It’s my cabin in the woods, my retreat. There are occasional visitors, but for the most part. It’s just me and the journal. There’s more room to spread out. And there’s not as much shouting as there is on Facebook. Facebook are places in the city you hang out with friends and Twitter is like the streets where you can chat with your friends but strangers can join in too.

It’s nice to come here and visit from time to time and post my thoughts.

BOINC

Yeah, I don’t know what it stands for either*. It’s the acronym for the Berkeley distributed computing project. Back in the late 90’s I participated in the SETI@Home project. You let the software use idle CPU cycles to search for artificial signals from deep space. I participated for a few years and ended up earning 2000 credits. I printed out my certificate and it’s laying about someplace. Anyway the distributed computing project was so popular Berkeley created a platform called BOINC and now there are dozens of projects. Tens of thousands of computers have participated creating vast networks of supercomputing power very cheaply.

I’ve got two old laptops I’m using as home servers (one is for web development work). Originally the laptops were used to play around with Linux and also to do development work for clients. I ended up turning the first one into a print server on our home network. Now we don’t have to take our laptops into my office to print. Since this server is on all the time heating up the room (slightly), my mind harkened back to SETI@Home. I knew there were other projects so I looked at the list to see what struck my fancy. I found two. MilkyWay@Home and climateprediction.net.

MilkyWay@Home uses data from the Digital Sloan Sky Survey to help generate an accurate 3D model of our own galaxy. The other climatepredition.net is to run climate models and test the accuracy of climate models up to the year 2100. I chose the latter first as it seemed to be more practical. Actually I ended up choosing both, and I’m running each on their own laptop.

Although I accept the science for global warming, if I discuss it I don’t need to base my arguments on climate models. There’s plenty of hard evidence that humans have altered the climate. However, we do need to be able to predict the climate if people (mostly Americans) do not change the way they live to stop climate change. Computer climate modeling got underway in the 1970’s and those models have gotten more accurate and computers have gotten immensely more powerful since them. It would be useful to test to verify how accurate those models are. And if they are off then they can be improved.

If it turns out the climate models predict less serious consequences of human activity and those models have been made more accurate then that would be a good thing. I think it’s unlikely but we won’t know until we look. I suspect (and computer models have already predicted) that human caused climate change is going to be very bad for us. But we still have a window of opportunity to mitigate the worst consequences. We can’t stop it, but can slow it and eventually reverse it, but that will take centuries. However, that window is closing, and I don’t know how much time we’ve got.

Whether it’s for fun or serious reasons these distributed computing projects allow citizens to participate in large projects. And as computing power continues to improve these projects will help to solve pressing problems.

Since this server is on all the time heating up the room (slightly), my mind harkened back to SETI@Home. I knew there were other projects so I looked at the list to see what struck my fancy. I was hoping there’d be a distributed project studying Parkinsons’ disease. There are a few medical projects that tackle neurodegenerative diseases and study protein folding.  I thought what would be the next most interesting. I found two. MilkyWay@Home and climateprediction.net.

 
MilkyWay@Home uses data from the Digital Sloan Sky Survey to help generate an accurate 3D model of our own galaxy. The other climatepredition.net is to run climate models and test the accuracy of climate models up to the year 2100. I chose the latter first as it seemed more practical. Also, I’m annoyed at a friend of mine who is a climate denier. He spouts talking points from the climate denial industry how climate modeling sucks. And isn’t useful. Eventually, he will come around and realize he was wrong. He used to be a Creationist and now understand evolution pretty well. Instead of letting religion blind him to science. He’s letting his politics do that.
 
I am actually running both projects on both computers. They are sharing resources. I had an issue with getting climatepredictions.net going on the print server laptop. Turns out they’d only let you download one data set per day. So I grabbed the MilkyWay@Home project as well.

However, that window is closing. I don’t know how much time we’ve got. We flagrantly wasted the last 10 years and I suspect we only have at best another 10 years to address it. Certainly not more than 20.

2011 The Year of Destruction 2.0

"These goes to 11" — Nigel, Spinal Tap

2011 has been one heckuva year so far. From Tunisa to Egypt to Lybia to Wisconsin to Japan. From protests to topping governments, to violence, to stripping unions of their power and now a big honking earthquake in Japan. The video the tsunami rolling up in Sendai will stay with me. I’ve never seen anything like it. I saw snippets of stuff like that with the Boxing Day Earthquake Tsunami, but this was from the air. Watching hundreds of acres of water roiling and filled with debris wiping out anything in its path.

I think I want to call 2011 The Year The Shit Hits the Fan. It didn’t take long for Republican victories in the House and state governments to see the destruction they are causing. Arizona has gone insane, allowing guns in schools (after Rep Giffords was shot in the head at point blank range in the head and a 6 others gunned down), and more anti-immigrant legislation being passed. Wisconsin just illegally stripped public unions of their rights and several other states are working feverishly at it. Why? It’s not to fix their budget gaps. It’s the last defense against privatizing the government. That was an avoidable disaster. Alas, those people who voted against their own interest will blame the resulting mess on the Democrats. I hope the protests in Wisconsin has finally woken the public and turn things around.

With so much turmoil in the world it won’t be long before the fundies to go crazy. Nobody send an unblemished red heifer to Israel or you won’t be able to turn the crazy off.
