Static Electricity Lab
The lab was quite interesting, and almost everyone got their share of discharges. The class went upstairs to another classroom, and took turns being electrocuted. Alyx had volumey hair, so what happened was not surprising.
Afterwards, I was chosen to be at the end of a chain of guys standing on Styrofoam, and I was near the sink. Mr. Brown told me to try to bend the water, but the splattering of the water caused electrical charges every 750ms or so,which shocked me and everyone in the line.

It was a great experience. Oh and I suppose I should mention that the Styrofoam is for insulation, allowing the person to act as a fleshy Leyden jar and storing the static charges instead of instantly depositing them into the ground.
And the hair stood up because the electrons, moving through the generator, through the hands, and to the hair, repelled each other, causing light things like hair to rise.

TYKTWD
My dad works at Polycom, where he does board bringup and drivers for office phone and teleconference hardware. He showed me how he gets latest code from CVS, and looks for causes of reported bugs or problems. An example was when after a USB host driver was unloaded, the device continued using a ton of power. It turns out the problem was someone forgot to deinitialize the driver after it unloaded, causing the power management to think the driver still needed a lot of power. Adding the deinit() function fixed it.
Afterwards we went to a sushi place where I saw Derek, and then I went with some of my dad's friends and former colleagues to the company where he used to work. There were only 3 people there, including me, so I got an office to myself. I was somewhat bored after a while, so they gave me a single-board computer, and gave me the assignment of getting Android to run on it. They had Linux running on all of the computers, which I haven't used too much before, but I was successful in the end. But then I learned that they accidentally gave me the wrong version of the x-load bootloader which caused the usb peripherals to not work. So while I got Google Android to run on it, I couldn't do any thing on it. Oh well, c'est la vie.

My favorite quote
Computer programming is tremendous fun. Like music, it is a skill that derives from an unknown blend of innate talent and constant practice. Like drawing, it can be shaped to a variety of ends – commercial, artistic, and pure entertainment. Programmers have a well-deserved reputation for working long hours, but are rarely credited with being driven by creative fevers. Programmers talk about software development on weekends, vacations, and over meals not because they lack imagination, but because their imagination reveals worlds that others cannot see.
- Larry O'Brien and Bruce Eckel in Thinking in C#
I like this quote because it shows how programming is an art, much like the well known Wordpress slogan, "Code is Poetry".
As a programmer, I agree. Code is poetry indeed.

Know Thyself
I am good with DNA/RNA, Cell Structure, and Tech, but I'm not too good with which the actions of each phase of Mitosis, and which order they go in.

Mitosis
Mitosis, the duplication of cells through splitting, is important because for single-cell organisms like bacteria, it's the only way for them to reproduce. It's also important for growth, as cells do not increase in size for a multi celled organism to grow; instead they split. The chromosomes duplicate, and each new cell gets half of the double amount, or the original amount, of chromosomes.

Comparison of the Five Major Browsers
Chrome
A browser developed by Google, built for speed, and based off the open-source project Chromium.
Pros: Executes JS, renders CSS, and caches pages faster than any of the other browsers. Extensions install instantly. Includes Developer Tools, which allow editing of HTML on pages.
Cons: Loads pages about 110 ms slower than Firefox. Extensions do not have as many permission.
Firefox
Open-Source browser developed by the Mozilla Foundation.
Pros: More extensions, and they have more control over the browser. Loads pages 110ms faster than Chrome.
Cons: To install extensions or themes, a browser restart is required. To edit HTML, you need to install Firebug.
Internet Explorer
Browser developed by Microsoft
Pros: Installed on Windows by default
Cons: No extensions, it’s the slowest browser, it breaks some CSS, it does not even support the latest version of CSS, it does not work with HTML5, and for me it constantly freezes on start-up. Also it uses ActiveX which is very vurnable to security attacks.
Safari
Browser developed by Apple, and is the Macintosh counterpart for Internet Explorer, but there is a version for Windows too.
Pros: Uses the WebKit engine, like Chrome. Cross-platform (except for linux). Has a debug menu like Chrome.
Cons: Images don’t have a context menu, tabs don’t have favicons, and no extensions.
Opera
An internet suite developed by Opera Software, that not only includes a browser, but a bittorent client, an email client, an IRC client, and a contact manager.
Pros: An Internet Suite, not a browser, containing lots of tools to use the web.
Cons: No extensions.
What I hope to learn in Digital Immersion.
In digital immersion, I am looking forward to learning biology, chemistry, and electricity.
I am nervous about trying to use LaTeX instead of a WYSIWYG editor such as Word, which will allow me to create better looking documents.
I know how to program using C#, a bit of Lua, some PHP and JS, and I'm trying to learn Java.
