Barack Obama just became the first US president to write a line of computer code (assuming George W. Bush never secretly indulged in PHP). At the White House yesterday, Obama sat down with students who were learning the fundamentals of JavaScript, the popular programming language used to create most web pages.
The line he wrote was:
moveForward(100);
“So I make the F in higher case?” Obama asked, correctly observing that JavaScript is case sensitive. “Semicolon?” (That semicolon is optional, but Obama apparently has a knack for recognizing JavaScript best practices.)
Obama was playing with a Code.org tutorial based on the popular Disney movie Frozen. In his line of code, the President called a function-moveForward-pre-defined by Code.org for the exercise.
Calling a function in JavaScript is simple: write its name exactly as it has been defined, followed by parentheses that contain its “arguments.” In this case, a single argument tells the program how many pixels to move a Frozen character forward. Because it’s measured in pixels, the argument has to be a number. If Obama had written moveForward(“three steps”), the program would have failed, offering only a cryptic error message and exposing the president to the near-perpetual state of frustration most software developers live in.
“This is Elsa?” Obama asked, referring to the movie’s main character.
Obama was promoting Computer Science Education Week and Code.org’s Hour of Code campaign, which encourages kids to try programming for at least one hour. “It turns out the concepts are not that complicated,” Obama told the students at the White House, though his attempt to explain it suggested otherwise:
“The basic concept behind coding is that you take zeros and ones, you take two numbers, yes or no, and those can be translated into electrical messages that then run through the computer…. So all it’s doing is it’s saying yes or no over and over again, and the computer’s powerful enough that it can read a really long set of instructions really quickly.”
Something like that.

I. The disadvantage OF working as an actor is that you can’t find a steady job.
II. We have just received an invitation TO her wedding.
III. The greatest difference BETWEEN both restaurants is their prices.
IV. Would you like to come FOR a walk? V. She lost weight after she went ON a severe diet.
Choose the only correct option, considering the use of correct prepositions:
I- Do you know I’m working at Macy’s now?
Oh, really? What do you do there?
I work part-time as a cashier.
II- Are you studying French this semester?
Yes, I am enjoying the course so much!
How often do you have classes?
Twice a week.
III- Where are you having lunch today?
At Laguna’s. Are you usually going there?
Yes, almost every day.
IV- What do you do in your free time?
I often go to the seaside.
Are you going there this weekend?
No, because I think it’s raining on Saturday.
Choose the only possible option, according to the correct use of simple present and/or present continuous tense in the dialogues above:
The Naval Nuclear Propulsion Program (NNPP) started in 1948. Since that time, the NNPP has provided safe and effective propulsion systems to power submarines, surface combatants, and aircraft carriers. Today, nuclear propulsion enables virtually undetectable US Navy submarines, including the sea-based leg of the strategic triad, and provides essentially inexhaustible propulsion power independent of forward logistical support to both our submarines and aircraft carriers. Over forty percent of the Navy's major combatant ships are nuclear-powered, and because of their demonstrated safety and reliability, these ships have access to seaports throughout the world. The NNPP has consistently sought the best way to affordably meet Navy requirements by evaluating, developing, and delivering a variety of reactor types, fuel systems, and structural materials. The Program has investigated many different fuel systems and reactor design features, and has designed, built, and operated over thirty different reactor designs in over twenty plant types to employ the most promising of these developments in practical applications. Improvements in naval reactor design have allowed increased power and energy to keep pace with the operational requirements of the modern nuclear fleet, while maintaining a conservative design approach that ensures reliability and safety to the crew, the public, and the environment. As just one example of the progress that has been made, the earliest reactor core designs in the NAUTILUS required refueling after about two years while modern reactor cores can last the life of a submarine, or over thirty years without refueling. These improvements have been the result of prudent, conservative engineering, backed by analysis, testing, and prototyping. The NNPP was also a pioneer in developing basic technologies and transferring technology to the civilian nuclear electric power industry. For example, the Program demonstrated the feasibility of commercial nuclear power generation in this country by designing, constructing and operating the Shipping port Atomic Power Station in Pennsylvania and showing the feasibility of a thorium-based breeder reactor.
