prompted network devices are identified by its mac address, which is 6 byte / 12 hex characters (1234abcd5678 for example). a restful api exists to check the status of a network device (http://localhost:8000/device/check/1234abcd5678, another example.) assume a large dataset exists that contains a large set of device identifiers in the form of mac addresses (over 10,000 ). also assume that the device identifiers (mac addresses) come from a data source / stream that separates each mac address by a newline. the restful api can take around 5 seconds to complete a single status check, checking device status is a relatively long running task which makes this an i/o-bound problem. write a python solution that processes mac address with the goal of: minimizing runtime, minimizing resource usage and generalizing methods and procedures.
Answers
An efficient solution is to use concurrent processing with the asyncio and aiohttp libraries.
The solution involves reading the large dataset of MAC addresses, separating them by newline, and then utilizing asynchronous programming to concurrently send multiple requests to the RESTful API to check the status of each device. By leveraging the asyncio and aiohttp libraries, the solution efficiently handles the I/O-bound nature of the task.
Using concurrent processing allows for parallel execution of multiple requests, significantly reducing the total runtime. The asyncio library manages the event loop, scheduling and executing tasks asynchronously, while the aiohttp library serves as an asynchronous HTTP client to make requests to the API. This approach optimizes resource usage by avoiding blocking operations and efficiently managing I/O operations.
By implementing this solution, the Python program can process a large dataset of MAC addresses, perform status checks on each device via the RESTful API, and accomplish the goal of minimizing runtime and resource usage. Additionally, the generalized approach allows for scalability and adaptability to handle large sets of MAC addresses in a variety of scenarios.

Some products are biased against left-handed people. Which is more difficult to use for a left handed person?
Answers
Answer:
Bias against left-handed people is a bias or design that is usually unfavorable against people who are left-handed. Handwriting is one of the biggest sources of disadvantage for left-handed people, other than for those forced to work with certain machinery. About 90 percent of the world's population is right-handed, and many common articles are designed for efficient use by right-handed people and may be inconvenient, painful, or even dangerous for left-handed people to use. These may include school desks, kitchen implements, and tools ranging from simple scissors to hazardous machinery such as power saws.
Because most people are right-handed, most everyday items are mass-produced for ease of use with the right hand. Tools, game equipment, musical instruments, and other items must be specially ordered for left-handed use if they are even produced and are usually more expensive than their right-handed counterparts. At least one specialty store sells only left-handed items.
Here is a list of products that are hard to use against left-handed people:
1. School Desks
Remember those desks we sat in at school? Guess who they were made for? Yep. Right-handed people. If we didn’t pass all our exams, it was probably because of the awkward way we had to sit and write in those desks.
2. Three-Ring Binders And Notebooks
Ever try using a three-ring binder or a spiral notebook as a left-handed person? Not easy, is it? Spirals making indentations in our left hand?! No thank you! Believe us, we feel your pain!
3. Cameras
If you think about your camera’s photo-taking button, where is it? Yep. On the right! In fact, a lot of the most-used buttons are on that side!
4. Car Cup Holders
Unless you’re sitting in the passenger seat, cup holders are generally not made for left-handed drivers. Though more and more cars have cup holders throughout the vehicle these days. Still, this should become standard for every vehicle, just to make it fair for the left-handed population.
5. Credit Card Swipers
We know—when will they make a credit card swiper for left-handed people?!
6. Coffee Mugs
Do you know those mugs with the messages written inside that become revealed once you start sipping? Good luck reading them if you’re left-handed.
7. Can Opener
Think about it. If you’re left-handed, when’s the last time you successfully used a can opener (which was made for right-handed people)? Exactly!
8. Scissors
Especially when you were a kid, how hard was it to cut things out at school when the teacher distributed right-handed scissors to everyone? Or when your parents were buying you school supplies and couldn’t find you a pair of left-handed scissors anywhere? Thankfully, they’re easier to get your hands on now, but that doesn’t mean many a leftie didn’t struggle for years prior.
9. Ice Cream Scooper
We left the sweetest for last, since it may make you want to grab a scoop (or two…or three) of ice cream when you’re done reading this. After all, you deserve it! But seriously, why are so many ice cream scoopers made only for right-handed people?

A set of data with a correlation coefficient of -0.855 has a weak negative linear correlation.
Thus, A correlation coefficient gauges how closely two variables are related to one another. The Pearson coefficient, which has a range of -1.0 to +1.0, is the correlation coefficient that is most frequently employed.
Two variables that have a positive correlation tend to move in the same direction. Two variables with a negative correlation tend to move in the opposing directions.
While a correlation value of -0.3 or lower shows a very weak association, one of -0.8 or lower suggests a strong negative relationship.

Answers
To find the maximum and minimum value in a 2D array, such as milesTracker, you can use nested for loops to iterate through each element in the array.
Here's an example code snippet that assigns the maximum value to maxMiles and the minimum value to minMiles:
```
int maxMiles = milesTracker[0][0]; // Assign with first element in milesTracker before loop
int minMiles = milesTracker[0][0];
for (int i = 0; i < NUM_ROWS; i++) {
for (int j = 0; j < NUM_COLS; j++) {
if (milesTracker[i][j] > maxMiles) {
maxMiles = milesTracker[i][j];
}
if (milesTracker[i][j] < minMiles) {
minMiles = milesTracker[i][j];
}
}
}
System.out.println("Min miles: " + minMiles);
System.out.println("Max miles: " + maxMiles);
```
In this example, we first assign maxMiles and minMiles with the first element in the milesTracker array. Then, we use nested for loops to iterate through each element in the array. For each element, we compare it with the current maxMiles and minMiles values, and update them if necessary. Finally, we print out the values of maxMiles and minMiles.
The sample output for this program might look like:
```
Min miles: 10
Max miles: 40
