River of the light-
When park-goers swarm Walt Disney World's Animal Kingdom later this month, Joe Rohde will be paying close attention.
The executive designer and vice president of Walt Disney Imagineering Creative has spent the last eight years overseeing the expansion of Disney's Animal Kingdom park, including its soon-to-be unveiled evening spectacle, "Rivers of Light." Rohde, a Disney veteran who said he started “at the bottom of the design ladder” in 1980, has also been leading the charge on Disney's "Avatar"-themed land, based on James Cameron's 2009 top-grossing film, which is slated to debut in 2017. The first of four planned sequels to Cameron's movie based on the fantastical world of Pandora will hit theaters a year later.
Rohde has overseen the development of Disney's "Avatar"-inspired land, seen in this illustration, which is scheduled to open at Animal Kingdom in 2017.-
Rohde likened the process of developing and constructing a major attraction to filming a major blockbuster film. The whole investment -- from "the morning of conceptualization to opening day" can take anywhere from four to five years, Rohde told ABC News. And in the case of Animal Kingdom, incorporating live animals can lead to other challenges.
"The inclusion of live animals changes design standards ... but it brings realism to design," he said in a phone interview. "Nature is a supreme, immutable value."
The millions of visitors who travel to Disney’s theme parks around the world -- more than 134 million in 2014, according to the Themed Entertainment Association (TEA), an industry trade group -- are not privy to the trials and tribulations of what it takes to bring an idea to fruition at Disney. Imagineers, as they're referred to at Disney, prefer it that way.
"We try to be invisible," Theron Skees, executive creative director for Walt Disney Imagineering, said in an interview.-
Skees started his Disney career painting artificial grottos and tunnels at Disneyland Paris' Pirates of the Caribbean attraction. Skees, who previously worked as a sculptor and set designer in film and commercials, has lived on three continents as a Disney imagineer, tasked with bringing the visions and interpretations of Disney characters and stories to life. The imagineering division, one of the most competitive and challenging practices within the Disney universe, has the sole responsibility of delivering "the magic" that visitors seek year after year. There are at least 1,500 imagineers currently in the company, according to a Disney spokesperson, with 140 disciplines within the group.
"There's the technical know-how, the creative vision, the planners and the operators," Skees said. "Imagineering is a pretty specialized group that requires a specialized mindset."-
And loners need not apply.
"You have to communicate and get an idea out there, whether that's painting, building or drawing models," Rohde added. "The ability to collaborate as a group is a must."
Skees reiterates that every imagineer is encouraged to submit ideas -- whether that’s for a new roller coaster, a live performance or costume design at one of the theme parks, hotels or Disney cruises.
“All ideas go through a process and it’s not exclusive to one person,” he noted.
Ideas can come from anywhere. Rohde immerses himself in books -- non-fiction, art history, neurology -- and vows to plow through the 35 stacked next to his bed, soon-to-be additions to his personal library of 5,000 books.
To be successful in this career “you need to find smart people to work under you and to read a lot,” he explained. Traveling the world? A necessity.
“We’re not making two-dimensional products. You need to know what places are really like,” he added.
Disney is the parent company of ABC News.
Hope you can get your work in on time.

Choose an efficient method of saving electricity. Briefly present the advantages and disadvantages of applying the chosen method in everyday life.
Answers
One method of saving electricity that is both efficient and easy to implement in everyday life is using energy-efficient light bulbs.
Advantages:
Energy-efficient light bulbs use significantly less energy compared to traditional incandescent bulbs, resulting in lower electricity bills.
They have a much longer lifespan, which means they need to be replaced less frequently, leading to additional savings and reduced waste.
Energy-efficient light bulbs come in a variety of styles and colors, making it easy to find one that fits your needs and preferences.
Disadvantages:
Energy-efficient light bulbs can be more expensive to purchase initially compared to traditional incandescent bulbs.
Some energy-efficient light bulbs, such as compact fluorescent bulbs, contain small amounts of mercury, which can be harmful to the environment if not disposed of properly.
Energy-efficient light bulbs may not work with certain types of dimmer switches, so it's important to check compatibility before purchasing.
Overall, switching to energy-efficient light bulbs is a simple and effective way to save electricity and reduce your carbon footprint. While there may be some initial costs and limitations, the long-term benefits of reduced energy consumption and reduced waste make it a smart choice for those looking to be more environmentally conscious.
An efficient method of saving electricity is by using LED light bulbs instead of traditional incandescent or fluorescent bulbs. LED stands for Light Emitting Diode and they are designed to be highly energy-efficient.
Advantages of using LED light bulbs:
1. Energy Efficiency: LED bulbs consume significantly less energy compared to traditional bulbs. They convert a higher percentage of electrical energy into light and produce less heat as a byproduct, making them more efficient and cost-effective in the long run.
2. Long Lifespan: LED bulbs have a much longer lifespan than traditional bulbs. They can last up to 25 times longer, reducing the frequency of replacement and saving money on replacement costs.
3. Environmental Friendly: LED bulbs do not contain harmful substances like mercury, which is commonly found in fluorescent bulbs. By using LED bulbs, you can contribute to reducing hazardous waste in landfills.
4. Durability: LED bulbs are more durable and resistant to shocks, vibrations, and temperature changes compared to traditional bulbs. This makes them suitable for various environments, including outdoor lighting.
Disadvantages of using LED light bulbs:
1. Higher Initial Cost: LED bulbs are generally more expensive to purchase upfront compared to traditional bulbs. However, the cost is offset by their longer lifespan and lower energy consumption over time.
2. Limited Color Options: While LED bulbs offer a wide range of color options, the selection might not be as extensive as traditional bulbs. However, advancements in LED technology have expanded the available color choices.
3. Sensitivity to Temperature: Extreme temperatures can affect the performance of LED bulbs. In very cold temperatures, LED lights might take longer to reach their full brightness, and in very hot temperatures, their lifespan might be reduced.
Overall, using LED light bulbs is an efficient method of saving electricity due to their energy efficiency, long lifespan, environmental friendliness, and durability. Though they may have a higher initial cost and limited color options, these drawbacks are outweighed by the long-term benefits they provide. By adopting LED bulbs, individuals can contribute to energy conservation and reduce their electricity bills.

what are some basic commands to remember in terminal? windows 10
please help if you know
Answers
Answer:
If you just need a few, maybe this can help.
Explanation:
Cat - The cat command means 'Concatenate'. It prints the contents of a file or files to stdout. It's frequently used in Linux commands.
Touch - Using the 'Touch' command, you can create a file, or possibly just modify or generate a timestamp.
Move - The 'mv' command stands for 'Move'. As the name says, we can use this command to move files and directories from one place to another.
Chsh - The chsh command changes a user's login shell attribute. If you want to change the shell of another user, execute the command with root permissions.
Sudo - 'Sudo', or 'super user do', is a command that allows you to elevate your user privileges while executing the command to administrator privileges.
Most files in Windows are associated with a specific program that is assigned to open the file by default. At times, remembering these associations can become confusing. You can remind yourself by entering the command assoc to display a full list of filename extensions and program associations. You can also extend the command to change file associations. For example, assoc .txt= will change the file association for text files to whatever program you enter after the equal sign. The assoc command itself will reveal both the extension names and program names, which will help you properly use this command.
In Windows 10, you can view a more user-friendly interface that also lets you change file type associations on the spot. Head to Settings (Windows + I) > Apps > Default apps > Choose default app by file type
2.Cipher
Deleting files on a mechanical hard drive doesn't really delete them at all. Instead, it marks the files as no longer accessible and the space they took up as free. The files remain recoverable until the system overwrites them with new data, which can take some time. The cipher command, however, lets you wipe a directory on an NTFS-formatted volume by writing random data to it. To wipe your C drive, for example, you'd use the cipher /w:d command, which will wipe free space on the drive. The command does not overwrite undeleted data, so you will not wipe out the files you need by running this command.
When you run the cipher command by itself, it returns the encryption state of the current directory and the files it contains. Use cipher /e: to encrypt a file, cipher /c: to retrieve information about encrypted files, and cipher /d: to decrypt the selected file. Most of these commands are redundant with the Windows encryption tool BitLocker.
3.file Compare
You can use this command to identify differences in text between two files. It's particularly useful for writers and programmers trying to find small changes between two versions of a file. Simply type fc and then the directory path and file name of the two files you want to compare.
You can also extend the command in several ways. Typing /b compares only binary output, /c disregards the case of text in the comparison, and /l only compares ASCII text.
So, for example, you could use the following:
fc /l "C:\Program Files (x86)
The above command compares ASCII text in two Word documents.
4.Ipconfig
This command relays the IP address that your computer is currently using. However, if you're behind a router (like most computers today), you'll instead receive the local network address of the router.
Still, ipconfig is useful because of its extensions. ipconfig /release followed by ipconfig /renew can force your Windows PC into asking for a new IP address, which is useful if your computer claims one isn't available. You can also use ipconfig /flushdns to refresh your DNS address. These commands are great if the Windows network troubleshooter chokes, which does happen on occasion.
5.Netstat
Entering the command netstat -an will provide you with a list of currently open ports and related IP addresses. This command will also tell you what state the port is in; listening, established, or closed.
This is a great command for when you're trying to troubleshoot devices connected to your PC or when you fear a Trojan infected your system and you're trying to locate a malicious connection.
6.Ping
Sometimes, you need to know whether or not packets are making it to a specific networked device. That's where ping comes in handy.
Typing ping followed by an IP address or web domain will send a series of test packets to the specified address. If they arrive and are returned, you know the device is capable of communicating with your PC; if it fails, you know that there's something blocking communication between the device and your computer. This can help you decide if the root of the issue is an improper configuration or a failure of network hardware.
7.PathPing
This is a more advanced version of ping that's useful if there are multiple routers between your PC and the device you're testing. Like ping, you use this command by typing pathping followed by the IP address, but unlike ping, pathping also relays some information about the route the test packets take.

In a minimum of 250 words, discuss the technological problems that can occur when consumers emphasize on speed over security.
Answers
1. Vulnerabilities and Breaches: Emphasizing speed often means sacrificing robust security measures. This can lead to vulnerabilities in software, applications, or systems that attackers can exploit. Without adequate security measures, data breaches become more likely, exposing sensitive information such as personal data, financial records, or trade secrets. The aftermath of a breach can be detrimental, including reputational damage, legal consequences, and financial losses.
2. Malware and Phishing Attacks: When speed takes precedence, consumers may overlook potential malware or phishing attacks. By rushing through security checks or bypassing cautionary measures, they inadvertently expose themselves to malicious software or fraudulent schemes. These attacks can compromise personal information, hijack devices, or gain unauthorized access to networks, resulting in financial losses and privacy violations.
3. Inadequate Authentication and Authorization: Speed-centric approaches might lead to weak or simplified authentication and authorization mechanisms. For instance, consumers may choose easy-to-guess passwords or reuse them across multiple platforms, making it easier for attackers to gain unauthorized access. Additionally, authorization processes may be rushed, granting excessive privileges or overlooking necessary access controls, creating opportunities for unauthorized users to exploit system vulnerabilities.
4. Neglected Updates and Patches: Prioritizing speed often means neglecting regular updates and patches for software and systems. By delaying or avoiding updates, consumers miss out on critical security fixes and vulnerability patches. Hackers actively exploit known vulnerabilities, and without timely updates, devices and systems remain exposed to these threats, making them easy targets.
5. Lack of Secure Development Practices: When speed becomes the primary concern, secure development practices might take a backseat. Security testing, code reviews, and quality assurance measures may be rushed or ignored, leading to the inclusion of vulnerabilities in the software or application itself. These vulnerabilities can be exploited by attackers to gain unauthorized access or execute malicious activities.
To mitigate these problems, it is essential to strike a balance between speed and security. Consumers should prioritize security measures such as using strong passwords, enabling multi-factor authentication, regularly updating software, and being cautious of suspicious links or emails. Service providers and developers must also prioritize security in their products and services by implementing secure coding practices, conducting thorough security assessments, and promptly addressing vulnerabilities. Ultimately, a comprehensive approach that values both speed and security is crucial for maintaining a safe and efficient technological ecosystem.

What is Hardware?
The physical components of a computer, such as its chassis, CPU, RAM, monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers, and motherboard, are referred to as computer hardware.
Software, on the other hand, is a collection of instructions that may be stored and executed by hardware. Software is referred to as "soft" because it is flexible, but hardware is referred to as "hard" because it is rigid in terms of modifications.
Software often instructs hardware to carry out any command or instruction. A useful computer system is one that combines hardware and software, while there are also systems that use simply hardware.
