Several weeks ago in comp sci

We have taken a quiz on the old topic and moved onto the new topic of ands/ors. this new topic is just like finding values to a matrix in math; easy, but rather tedious and takes a while when the problems get bigger. The most annoying thing that happens relating to these is when you get one part of the order wrong in a problem and then have to do basically the exact same problem repeatedly but with a slightly different answer. An example was a&&b||c&&d where did and then or then and instead of and then and then or. On some problems this messes up the outputs and becomes really annoying. Otherwise nothing else is new and I mostly get the content.I have noticed that we are doing some review recently, and I think it would be good to step up the review amount in order to get ready for the midterm, because there is nothing like test corrections or retakes for that.

Cool new blog technology

This week on Engadget I read an article about how different tv companies have blocked their video content from being shown on google TV. This has been done apparently because they do not want people to just use their internet in order to view tv shows and not pay for cable. TV companies want to show you as little as possible in order to make you buy a product and thus they do not like to have people watch their videos for free on TV. I think that it is sill that TV companies literally put a block on their website in order for it not to be shown on TV. If people really wanted to watch online shows on their TV, I am pretty sure that they could use their TV as a monitor. The whole debate seems rather silly to me and I think it will annoy some of my peers to see how wrapped up the companies are in profit, rather then the actual product and future of the industry.

Weekly Compsci Update

Last week in Comp Sci, we learned a fair bit. We reinforced the idea of if else if, and started to use loops. We only used for loops to start, which probably simplified the process and made it much easier to understand. The one thing that I made repeated mistakes on though was where to put the semicolons in on for loops. I would always miss one here or there, so I would have errors come up in my programs. This is little more then an annoyance, because it takes little time to fix, but I kinda hope that it will become habit to put the semicolons in the right place soon. Another thing which took me a while to get was right were the for loop stopped. I did not know whether or not you apply the multiplier before or after the Boolean check, but this was resolved by doing several practice problems and having the small portion of the concept re-explained. We also now have a new system of powerpoint presentations which I prefer. Now our screens just have a small bubble which the teacher controls, so that we can work at the same time as we listen and learn, which streamlines the process. That is all for last week cya.

Cool new Blog Tech

This week on Engadget, I read a post about how someone managed to make a gameboy emulator using JAVA. Apparently the only reason that they made the emulator, was in order to prove that java could be useful for such a device. He wanted to show that java was not only useful for creating games, but whole systems. I found this to be pretty cool because up until this point I think that my class mates and I have seen little real world application to what we have been doing, so seeing such a post could remind us that there is more to what we are learning then the ability to find the letter m in compsci. This blog post seemed to show a possible future project for us which made me more excited then ever to be able to do such a thing.

This week in Compsci

Well actually it would be last week, but whatever. It was rather uneventful due to my absence two of the three days of class. On the day that I was there though, I learned about if else if statements and cases. These seemed to be fairly simple, due to their similarities to previous concepts. The only slightly confusing thing about cases, was the need for breaks after every line. One problem I had with the labs that we were supposed to work on was that I did not realize how to use if else ifs at first so I just us if elses. This makes your code really long and complicated with a whole bunch of brackets, so I managed to confuse myself and just make the whole code more complicated then it needed to be. I do not think that these concepts are very difficult so I am glad that we are working on labs a lot more and doing a lot more individual work. A quick explanation of how to use if else ifs and viewing a power point cleared the situation up. Otherwise nothing else happened and the week was uneventful

Today I read on engadget about how the ISS (international space station) is marking its tenth anniversary of continuous habitation. This means that there has been someone living in the ISS at all times for the last ten years. I think this is fairly incredible due to the amount of resources which it takes to keep someone alive. It is about 10000 dollars a pound to send matter to the ISS so just getting food up to the ISS is expensive enough. Getting oxygen and keeping sanitary conditions on board are also of concern, so to have been running for 10 years strait, is quite an achievement. I thought this was interesting because it proves that space hotels and residences are not just possible, but quite creatable for those rich enough to afford this. I have recently heard many people talking about a want to go into space or experience 0 gravity, and I thought that it would be neat to see this commercially happen for extended periods of time.

Weekly Comp Sci Update

This week has just been a lot of catch up work for me, so I got little in the way of labs done. Of the labs which I did get to though, I found them to be fairly easy. This week I worked on if else statements, and I seem to have gotten them down fairly well, aside from putting a semicolon where it does not belong, or creating weird syntax, this concept seems fairly self explanatory. Like I mentioned earlier, the one thing I had trouble with was the syntax and punctuation, but a quick tutorial from one of my peers quickly alleviated the situation. Other then that, this week was pretty bland and little else happened.
