I love the morning!

Yeah, mornings rock when I don't have to work.

Wednesday night we had a few tornados in the area, I lost power at about 7pm that night. Nothing big really, a few trees down and the usual. The damage from this was nothing compared to what is currently going on in the gulf. This is really about how I lost my last mornings of joy.

Thursday came around, and I get a call at 7am from my boss, he told me they do not have power yet and I should wait by my phone. I kindly informed him that I have today off, but thanked him for the information. I had to bring my girlfriend into work because bla bla bla early in the morning, at this time there were about 110,000 people in my area w/o power. So 1 out of 3 people are unshowered and looking for coffee, the local gas station was closed and all the ones I drove by were packed full. I was one of the unshowered in need of a pack of smokes and a cup of joe. Not that interisting, I know. Just getting to the point, I left home a little after 7am and arrived home around 10am, it took like 3 hours to get coffee and smokes. I tried to call my family to see if anyone needed help with some cleaning up, didn't get a hold of any of them. I decide to move my computer desk now that it's off, and I can't turn it on. It was fun, and I am happy that I have it where it is now, but I ended up sitting at home with no power until about 5pm. Then I had a serious game session, yay.

Friday morning, I am scheduled to work at 9:30 am, I get another call around 7am telling me the same thing, and to keep my phone near by in case the situation changes. Woohoo! Free day off! I headed off to the super market to get a bag of coffee and something for lunch. I was all comfortable in my new setup, playing around with ADO.NET when I got another call, "we expect to have phones soon, so head in". That call came in at around 10 am, I took 30 minuets to get ready and headed into work for the day. I live near a major highway, and take it to work. I had to cross the highway to get my coffee this morning, and there were no problems, power was on all over the area. My work was on the other side of the river, so I just expected the general area was all back up. Not true, I have not gone south on the highway since going to work on Wednesday, three stop lights were out, so they were reduced to 4-way stops, it only took like 20-25 minuets to go the 4 miles I have to drive to get to work. When I get there, they don't really have power, just partial power. We had some 30 extention cords running around powering up CS workstations. They told us tech-support people that we would not have power to our workstations, that we would have to take notes on paper and just do all the support by memory and asking tons of questions. Good grief! We stood around for about 1 hour before we actually started taking calls. I understand that they want to be back in operation ASAP as a company, if customers can't call in orders as normal, they are losing money. However I also think they should have waited until they could say "ok, we are ready for you, come in now". Tomorrow I will see what time they clocked me in at, I think I should be getting paid for all the time I stood there being ready to goto work. I work until 6:30 pm, one of the other guys who works until 7 asked about breaks for the day, the first thing out of my bosses mouth was "well, we started late today..." and ended with no breaks. We were like WTF?! He came back about a minuet later and said, just make sure you only go one at a time. Thats more like it buddy, thank you! Shit, no breaks after starting only 1 hour late in a 9 hour day (normally minus 30 for lunch, but not today). Since I got there around 11, I was there for 7.5 hours, don't try to tell us we don't get a break. After that the day was pretty much ok, they brought in about 12 pizzas for us, so we didn't have to take a lunch. Because they were down for a day, they asked if some of us would work early/late on Saturday to help take calls, in hopes that customers who didn't get to order Thursday would try to call and our company might be able to pickup some "lost" orders. I work Saturday every week anyway, so I said I would work the extra hours late, because I don't like getting up on Saturday for work, my start time is 1.5 hours sooner than in the week, no way I was going to make it in 1 hour earlier than that.

Saturday we had a generator and air compressor rented, the power company said since we have partial power and other places have none, we were on the bottom of the list. They said it would be 3-5 days (from Thursday) before power would be restored fully. Saturday was actually nothing to complain about really, we had a lot of extra people. I usualy get stuck on CS calls all the time and have to clear thoes before it will send in the TS queue. With all the extra people, it was really slow and I was able to poke around online when I was not on a call. Plus we only stayed 1 hour later than normal, insted of 3. The call volume was not as high as they had anticipated. My friends are having a baby, and I went to my first baby shower after work. It was boring.

Sunday, this is soo much better. In my favorite spot, I have a nice playlist put together, just started drinking my 2nd pot, just finished putting summaries on two classes I made for my GTR File project, I couldn't be happier. I added support for multiple input files when importing to archive, and also a new file button. Infact I just found out about how to add summaries to my code. For all of you who don't know already, if you type three slashes "///" above a function or variable like you are going to comment it, it will fill in the "" tags for you. Makes it nice so you can comment for intellisense.

I doubt many people are interested in this, but here are the two C# classes I made. They are not really finished, I am working on getting the DataBlock to be a MemoryStream insted of a byte array, so keep that in mind if you actually read the code.
