    right... if you cannot even discuss basic flags or basic concepts, but can google, that's all that's needed to be a good competent programmer, right? Because good enough is good enough.

    no wonder USA is losing its edge, with this kind of thinking.

    Open book tests are terribly difficult. When I took my legal courses they were all open book, my POA(provincial offences) tests? All open book, same with traffic law, again all open book. The very best of all these tests are written by instructors who know their material and write their own questions based on the material that they've taught through the year.

    That means you not only need the book, but you need to understand it, and have attended the classes to make it through the exam. People think they sweat bullets on a 80 page exam? Hah. Try 13 pages, where it's all open book and you're required to break down a full construct question that's worth 10% of the exam mark.

    The thing about cheating is people assume it wont happen in offline courses. Cheating is possible whenever an entire class of students is given the same series of questions. In our world of today we don't have to do it like that anymore. We can mix things up by giving each student some exclusive questions so that they cannot get an A by cheating. The professor could simply prepare some questions specifically to be exclusive and then sprinkle these questions around so that every student has a slightly different exam.

    If students cheat they'll eventually hit the roadblock.

    I see where the GP was going. It's better to ask more complex questions where it tests the person understands concepts than that they can memorize. Problem is that it means the grader has to do more work when grading

    Let a computer artificial intelligence generate both the test and then do the grading. This way the Professor can focus entirely on teaching.

    Good programming tests ask about concepts and show code and you have to pick an answer to describe what the code is doing. These sorts of tests even I would have trouble with, but these sorts of tests cannot be cheated on if the questions and code is randomly presented.

    more tests need to be open book / open Google.

    Why should people who can cram but don't know what they are doing get better marks then people who know what they are doing but are not good at craning.

    What the point of craning command line flags when you don't want why you want to use them that way vs say looking at MSDN / look at the build in help ECT?

    I agree but for certain tests such as tests you probably do need to do multiple choice. Simply randomize the questions and it becomes very difficult to cheat. With randomized questions then online tests become harder to cheat on than offline tests because offline tests there still might be transmissions of some sort going on because when you got 50 students in a room all taking the same test or similar test this can happen. Make the questions randomly generated and make them take the test online and from home or at a special test taking center and now it's much harder to cheat.

    The problem here is that the Public University they went to sucked. It's not a problem with online courses, it's a problem with poorly designed tests. If you've taken an online course before you'll know some courses have tests which are as easy as they describe but you also know some courses have tests which are generated on the fly by some algorithm so that it's harder to cheat the test than to pass it from studying.

    That is the solution, make it harder to cheat than not to cheat.

  5. Offline degrees are suspect as well on Students Looking For Easy A Target Online Courses, Where Cheating Is Easier · · Score: 1

    That's one of the biggest reasons why online degrees are suspect.

    Of course cheating has always occurred in bricks and mortar schools, too, but it's supposed to be harder. For STEM courses, exams usually make up the majority of the grade, and are held in proctored halls. At the best schools, cheaters who are caught are dealt with harshly; usually they fail the course (which goes on the official transscript) and sometimes they are expelled.

    If you want to cheat offline it's not like the professor can see everything students do while taking an exam. Most exams in college are given in a classroom where students can visually see one another, hear one another, electronics can often be in that room and can emit or transmit. Basically if you really want to make a room cheat proof it has to also be emissions proof, sound proof, and each desk has to be isolated.

    This is possible but it's not something you see any of the public schools doing. I never cheated and I have the grades to prove it, but I've always been intelligent enough to know how to cheat if I really wanted to and from the perspective of a hacker it's easy. At the end of the day it's better to actually know your subjects because you'll actually make use of that knowledge in the real world and college is just training for that. If your goal is just to get into an ivy league school and rely on name brand value then cheating is a route to doing that but if your goal is to actually be good at a particular job or have the knowledge cheating isn't worth it.

    And on some exams cheating can be made entirely impossible. If we want to make it impossible just put each student in a faraday cage isolated room. One room per student, and 20 rooms to allow 20 students at a time to take the exam. Let a private corporation handle the exam instead of public institutions and you'll see it's a lot harder to cheat. Finally make the test questions completely randomized so that it's impossible for the students to know in advance what will be on the exam.

    Randomly generated questions could be used to stop cheating online. I've personally taken exams like this and it's impossible to rely on a doc of any sort when you don't know what questions you'll be facing.

  6. Generate new questions for each exam on Students Looking For Easy A Target Online Courses, Where Cheating Is Easier · · Score: 1

    Simply take a course where you were already familiar with the subject matter. (I really suspect a lot of the students in the language classes I took were already fluent in the language. Boy did that suck for me.)

    One of the ways I've seen online exams prevent cheating is to generate the questions on the fly and then time limit the exam so that there wont be enough time to try and find all the answers through cheating.

    That being said if someone is determined to cheat and puts in enough effort it's just as easy to cheat right in the teachers face as it is to cheat online. It's not like the schools have high tech surveillance so chances are anyone who really wants to cheat already is cheating. If they receive all As in classes which rely on multiple choice exams then there is a possibility of cheating.

    If the class is big enough the probability of cheating rises. One way to minimize cheating is to make each student take the exam in a sound proof fully shielded faraday cage cubical. This way they cannot see who is sitting next to them or behind them, they cannot hear, and no EMF can emit or transmit.

    It's pretty common to believe that no central source can control the internet - and it's true for the most part - with one major exception: IANA ultimately answers to the US Department of Commerce.

    In order for the internet to function, there has to be a central authority who determines who gets what IP addresses and domain names. That authority is under the control of the US. Sure you could create your own internets (yes, plural) with your own name and number rules, however if you can't all agree upon who gets what IP address blocks and domain names, you aren't going to have a very cohesive and universal network like the one we have today.

    Honestly, I am perfectly fine with the US having control over that, and in fact would much rather they hold the keys rather than the UN. If the UN had their way, that would mean countries who have heavy influence of the UN (e.g. China) would have their way.

    So far, the US has done a great job. Sure, we've had talks about filtering the internet (e.g. SOPA) many times, but unlike 90% of the other countries out there (Australia, UK, Germany, China, Iran, just to name a few,) we haven't acted upon any of them. Granted, we have taken extraordinary and unnecessary if not unethical measures, such as taking down megaupload, we didn't do so by ordering IANA to break the infrastructure.

    The best thing about the US having control, is that we've never done anything to dismantle the infrastructure in the name of politics. The UN wants control because they plan on doing exactly that.

    More governments arguing for control over the internet is better than just having one government and fewer people deciding,

    Each police officer could in theory operate thousands of drones all around the city. The drones could go from being large UAV's to toy airplane size, to insect size, to the size of dust particles, depending on how much money the police have and how drone is defined.

    In practice the smallest drone would be nano-dust which is about the size of a flake of rice. This would be too expensive today but if mass produced by the police all around the country the price would go down to the point where we'd have a police officer practically everywhere without any way to stop it.

    The main thing I could see them making sense for is replacing helicopters for following suspects if on a chase (a drone would be a lot cheaper and you could have a few engaged). But there are of other valid peaceful governmental uses of drones:

    * Surveying the city. You could use them to get an idea of what areas of town needed more work than others. You could do weekly flyovers just to see if streetlights were out in an area. You could build up a highly detailed aerial map of your city/county/state and then let the people make use of that data to make cool mapping products.

    * Work in tandem with other sensors to get video on an area where needed ASAP. Video of traffic accidents moments after they occur (or any sudden drop in traffic speed). Video of an area where gunshot detectors picked up shots.

    I don't at all understand the concern over drones, they are simply cameras that are more mobile than traditional surveillance cameras. Are people concerned with drones also concerned that police cars have cameras in them?

    Obviously if you included weapons on the drones that's a whole different matter, but I've not heard anyone say they are considering weaponizing them.
