*Sighs in Relief*

     So that's it. My presentation is finished! I'll be the first to say that I give a massive sigh of relief after I present something. I am seriously looking forward to sitting back, relaxing, and watching other people present their fantastic work. Based on what I've seen so far, I'm quite excited for what's coming next!

     Anyway, on to the point of this blog post. We've been assigned to grade ourselves. I've always been baffled by the effectiveness of this system. When I heard about it in elementary school, I always thought "So I can just give myself 100%?! Awesome!" But I quickly realized that there were underlying conundrums such as etiquette and honesty. On the TED Talk requirement sheet, there are 5 categories, so I will assign each of them 6 out of the 30 total points. So here I go. I'll attempt to do my best here.

      The first thing on the list of requirements for the TED Talk is "Four to Five Minutes". I believe that this one is fairly self-explanatory. The presentation should have been between 4 and 5 minutes. In all of my practice runs, I was between 4-and-a-half minutes and 5 minutes. I obviously didn't have the opportunity to time myself on stage, but I think I can safely give myself the benefit of the doubt that I either spoke slightly faster than normal, or was spot-on. I'll give myself a full 6/6 on that one.

     The next object on the list is "Visual Component". Now, this is broken up into two subcategories which, for the sake of fairness, I'll break into 3 points each. The first of these is "PPT, Prezi, Other?" I had a PowerPoint-like presentation for mine (I say "-like" because Linux comes with its own Office software called Libre Office, but I think you get the point). Now, I worked on this presentation all throughout Spring break, and during the weekend I got back. I made sure that it was tailored so that the titles, pictures, transitions, and everything else matched up with what I was saying during the presentation itself. I made quite a large effort to use as little text as possible because that is what we've been taught is good throughout our experience with PowerPoint presentations. I confidently grant myself a 2.5/3 in that aspect, granted that it certainly was not a perfect presentation, and should not be treated as such. The next subcategory is "Creative and Supplemental: You drive the presentation, not the visual." Now I think that I could have done a bit better in this aspect. I think that my visual did drive the presentation. Sure, I didn't have any real text-queues on the screen, but the pictures were the things telling me what to say. Does that not entail the visual "driving the presentation"? Thus, I'd say a 2/3 is an applicable grade.

     Moving on, the next category is "Content". Now, as this is broken into 4 parts, I don't think I'd be doing any justice by trying to break it up, so I'll just bring all of the subcategories together into one grade. The first subcategory is "Inspire through passion". As not many people are interested in computers, I find it to be quite difficult to do this. I tried to find a way to hook the audience and make the presentation apply to everyone by saying "everyone uses computers" in my first slide. However, I still doubt that I actually inspired anyone. However (again), I did hear quite a few "ooh"s and "aah"s as I set up my computer to present, so I will take that into consideration while grading. The next aspect of "Content" is "Show your product". I immodestly grant myself full credit on this category because... well... I built a computer. I showed my product by presenting from it. I find that to be quite an impressive accomplishment. Next up is "Explain your process". Now, granted that there was only a 5-minute time slot into which we had to try to cram everything, I still think I could have done a better job explaining my process. I probably wouldn't have been able to even get into a little bit of what I did, but I get the feeling I could have done a little more. Finally is "What is your purpose? What should the audience take away from your project?" I think I addressed this pretty well. Near the end of my presentation, I stated that my purpose was to explain that "You need to know what you want/need and how to get it. That way, you'll always have a chance to get it." Judging by the explicit nature of my statement, I think that I got the message across. I'd give myself a 5/6 on the "Content" section because, although I think I got a lot of content in, I certainly could have polished and altered it a little so that I could fit in some more.

     Next is "Organization". This entails the presentation having a logical order, from beginning to middle to end. My parents and I spent quite a lot of time editing my presentation so that it actually had a logical story-like order. I started with a (what I hope was a) hook, then I proceeded to talk about my life experience with computers, then on to my experience with the project itself, then on to the application of the project to my life and to others, then finally on to the message that I wanted the audience to take away from it. Then, at the very end, I displayed my final product. I believe that that is a relatively logical order, so I feel confident that a 5/6 is a reasonable grade in this category.

     The final category is "Delivery". This entails the presenter being "refined, poised, and enthusiastic". Was I refined? Ehhh... Maybe not so much. I heard the nervous cracks in my voice a couple of times, and I stumbled on my words a little. Next, was I poised? I think that this fits hand-in-hand with the refinement aspect of this category. So, yes and no. I was a bit nervous, so that got in the way of poise a few times. Finally, was I enthusiastic. As many know, I absolutely love computers. I research them day and night on my own time. I don't think of the research as work. It's just fun to me. I think that that love and enthusiasm did carry over into the presentation, even over my monotone voice! Overall, I did know my content from top to bottom, I knew how I wanted to present it, and I tried my best to do so. Nerves just got in the way a little. Thus, I give myself a 4.5/6 in this category.


Summary

"Four to Five Minutes":                         6/6
"Visual Component":                           4.5/6
"Content":                                               5/6
"Organization":                                       5/6
"Delivery":                                           4.5/6
                                                                       
Total Self-Assessment:                        25/30

The End is Near!

So it is the end of spring break, and presentation week is upon us! I believe I'm presenting this Tuesday, and I'm confident that I'll be able to present well. Also, I managed to build my computer! I'm so excited that I could finally get it built, AND IT WORKS! As it turns out, none of the parts came damaged, broken, or non-functional. I got up this morning at around 11:00 and went straight to work on it. By about 12:30, it was finished. I hooked it up to my TV in the basement, and it just... worked.So I'm quite thankful for this lucky turn of events! The only real disappointment regarding the build is the fact that the wireless adapter is not functioning. It seems that it is not compatible with Linux (which I'm running because a copy of Windows 7 costs like $90) but it's not that big of a deal because there's really nothing that I need on this computer that I can't just copy onto a flash drive from another computer and drag onto it. So, all in all, everything's great! I have a new, tiny computer that works and has my presentation on it! Here are a few pictures for your viewing pleasure:





P.S. - Good luck to everyone on finalizing their own projects, and also good luck to everyone on their presentations! I'm sincerely excited to see what everyone came up with! :)

Parts Are Ordered!

So this post should be quite a bit less "history lesson"-ish than the others. I have officially ordered the parts for my little computer from both Newegg and Amazon. I'm a little nervous, though, because the order confirmations said that the shipping might take between 5 and 8 days. Hopefully they get here by next Saturday! I will be sure to take lots of pictures so that everyone can see the progress being made. Have a great Spring break, everyone!

RAM. That's it, just RAM...

     So this week, I'm moving on to the next major part of my little computer build. As it turns out, my parents and I have been discussing the likelihood of actually building this system. It's still leaning towards the "likely" side, but I think I'll have to keep using my virtually non-existent powers of persuasion to keep them on my side. Anyway, on to the long, tedious post! Yay!

This week's part is RAM. RAM generally looks like this:


However, most modern models have heat-spreaders like this:



 
 
 
 
 
Now for the wonderful history lesson: The original way to store information in computers was vacuum tubes. These tubes stored information for use at a later time. In 1945, the ENIAC, the first commercially used computer, used thousands of vacuum tubes to store its information. Later, in 1952, Jay Forrester from MIT invented "Core Memory". This is what you are hearing when you hear things like "dual-core processor". Finally, in 1969, Intel released their first product, the 3101 Schottky. This was also the first step in the direction of modern RAM.
Intel 3101 Schottky
 

     Like all other computer components, RAM runs on a "clock", or a certain rate at which it processes information. In RAM, the clock has two pulses that happen every cycle. There is a positive pulse of electricity, and a negative pulse of electricity. The first type of RAM that utilized this capability was SDR (Single Data Rate) RAM. It was only capable of sending data during the positive pulse of each cycle. However, it was quickly replaced by DDR (Double Data Rate) RAM, which was able to send data during both pulses of the cycle, which made it twice as fast. After this major step, RAM began to evolve. DDR2 RAM, the evolution of DDR RAM, had larger bandwidth, faster clock rates, and allowed for higher voltages. These improvements made DDR2 much faster than its predecessor. Today, we are at the third step in the evolution of RAM, DDR3. Finalized in 2007, the architecture and specifications for DDR3 RAM increased clock rates while, at the same time, reducing voltage. This allowed for faster speeds that took less power to reach, therefore creating a more eco-friendly computer.
     Finally, on to the concept of "clock speeds". As I stated earlier, RAM runs on a constant clock, which allows it to run at a certain speed. However, different RAM modules are designed to handle faster speeds. These data rates for RAM are measured in mega-transfers (or megahertz) per second. For example, the lowest common RAM standard is DDR3-1066. That means that it makes 1066 mega-transfers every second. The fastest, which was just introduced by Corsair last week, is clocked at 3000mHz.



As for my project build, I have chosen Mushkin's Silverline 4gb kit. It consists of two 2gb sticks that run at DDR3-1333 speeds (as my motherboard can't handle anything higher. Surely this RAM will be able to do anything I could possibly need it to. I feel that it's a great cheap, effective solution for my system!






So, toodles to all, and have a wonderful time doing whatever it is you do. :)
