Computer Science

I am a beginner in the field and I don't know whether it is too silly to ask. What is the physical location(if any) of the four layers in TCP/IP model? Suppose I am using the application gmail, and has pressed the send button after typing in the mail when does application layer come into play and where is it located?Is it a part of the software and what of the other three layers?

I've had an idea where I want to have a series of nested if and else statements for decision making. The idea is that if I clone myself I will have two thinking units and two people working on the same task. Though the idea didn't go through because to construct the validity of a thought takes analysis and there really isn't an efficient way for computer to process it. Then I thought of a bot, a bot of myself that could possibly replace me at work that would automatically answer Skype and create programs. My boss probably wouldn't be happy to hear that but, imagine having an extra working unit of yourself. You can potentially earning money without having to be there, all …

I am looking for the program. Not the name of it. It would be nice to see the program behind some app that is simple yet useful. (Also please help me figure out how to thank replies to queries on this forum).

hello everyone, i dont know if im in the right place to ask this. perhaps im still on the very first forum im trying to seek help for this. so as the title says, im a beginner in PHP and im really having a hard time trying to create this system that is LAN-based. ive been working on this for more than a month but im really getting desperate to finally sought help from forums like this cause this project of mine has a deadline. i need this done by the end of july. the system has two users: students and admin the students are the ones of course who are going to evaluate the teachers on each of their subjects their teaching the admin only has the authorizat…

For P = NP I must prove that a Non-Deterministic algorithm can be the same as a deterministic algorithm. A Non-Deterministic algorithm may use random variables to change the algorithm based on different inputs. For this I am using the current time which is just a counter to generate a random variable in a deterministic manner. We will assume that the non_deterministic is truly random yet the deterministic algorithm is pseudo random. It equals the exact same thing though. <script> function deterministic(input){ var d = new Date(); var n = d.getTime(); var n =""+n+""; var rand = n.slice(n.length-1,n.length); document.write…

So I have a custom built computer, about 3 years old...stowed under my desk. I'm trying to extend its life as long as possible (no issues right now..just good prevention), so I have it at an angle away from the wall and slightly sticking out from under the desk so the air exiting the computer doesn't get too hot. I also have a fan blowing on high at the exit vent, so it pushes the air coming out of the computer faster. Is htis the best i can do too make sure it doesn't overheat? I also has coolant too. Here's a diagram of the set up.

what needs more time and resources to design between hotspot design and internet usage control?

Hello. I am studying turing machines. I know that a turing machine can read/write a symbol, move to left to right, and enter into a serie of states. But i don't know how the transition function works. I don't know how the turing machine can reference values when it only performs sequentialy operations. Please, give me an example explaining the addition of two binary numbers using it. Explain me also more about states. Thanks.

Do you know of an A/B testing tool that can compare my old website to my new one? The two websites have a completely different design. I'm not talking about running experiments on the same website by altering something on the website. I searched on Google but I couldn't find anything. Please let me know if you know of some tool that does this. Thank you!

Don't worry, this isn't intended as an open thread for what the best language is. Specifically im looking for a language that has easy to build GUI's but also crunches numbers, ALOT of them. I'm somewhat loathed to pick up any .net language, and i guess there arent many with numerical advantage. Cant use Java purely because theres too much effort with compatibility of DLL's that i require. I was using C# because its very easy to get started with but im thinking perhaps a c++ framework would be best with QT or such for graphical needs. c is what i've programmed in most but its too low level, c++ seems pretty strong but i dont know of any other languages that …

I use MySQL database for couple of weeks. Today I have worked in my database I saved it. Then I tried to open the database and saw - Index file is crashed. I checked backup copy it disappeared. Can someone suggest what can I do?

If you're wondering what, you can see: https://www.youtube.com/watch?v=rCHX8QU3cLI Intros like this, are highly compressed. The first loader is called, which is decompressing the real intro code. Then executed. Typically code is generating procedural fractals, and procedural textures, which are used to generate 3D image. Best Regards!

Hi guys, just doin some number crunching on some "data sets" that im creating using the random function (in scilab), now the values vary from 1000 to 1100 and im using some basic logic on these values. Now whats striking me as odd is that although ive done exstensive tests the results always give a similar mean, not a single run has thrown out say numbers over 1050 even 20 times in a row, i know its the law of probability but should i not see some freak results atleast once? I would prefer not to apply my own logic to get irregularities if possible but thus far the "randomness" is pretty predictable.

I am a computer science major. Actually, I just recently decided to pursue this field. The subject matter has grown so much on me that I'm very drawn to it, but I'm still a newb to computers and the field of computation and I haven't even got into the computer science part of the program. I will be attending my state's flagship school after graduating from my current community college. I definitely plan to go to graduate school and am looking to immerse myself into the study. My question is what are some good publications (magazines, etc.) on computer science? I want to read frequently on the topic and learn about the research being done in the field. I'm also int…

Currently making a bejeweled like tile matching game. However I can't seem to make matches in more than one direction for some reason. The checklink function is checking the matches up at the moment and it should work for down if I change the minus to plus it should work but it isn't. function setCookie(cname, cvalue, exdays) { "use strict"; var d = new Date(), expires = ""; d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000)); expires = "expires=" + d.toGMTString(); document.cookie = cname + "=" + cvalue + "; " + expires; } function getCookie(cname) { "use strict"; var name = cname + "=", ca = document.cookie.split(';'), c = "", i = ""; …

Trying to update text in canvas saving the background. So far I haven't been able to not use clear rect. I can do it using a framework but I would rather be able to do it without one. Here I can save the background data and then redraw it but that isn't a good solution. Is there a way to update already filled text??

Hello! I made paid application for Android. Published it. And noticed weird message "application is not compatible with your device" after going to Google Play Store website of my application, from either desktop computer and devices. They used to work with application when I was sending them through HTTP/FTP. There is plentiful of threads about "android application is not compatible with your device" on stackexchange etc. websites for programmers. But nothing what they wrote, worked in my case. (one of the most interesting was that some devices have partitions, and have to have application .apk file size smaller than f.e. 32 MB, otherwise devices (men…

Hey all, First off, I apologize if this isn't the correct spot to ask about career advice. I'm looking to transition mid career into the cybersecurity/network security field of computer science. I have a bachelor's degree in an unrelated field, no IT experience or education, and have been employed in the public service sector for a number of years. Always had an interest in IT, however my first career choice had me go in another direction. So I was wondering what would be the best path to take in starting this transition. What have some of you done? My thought to get started is to get a computer science certificate from a community college or state university …

hai, I am a programming student and I been asked to do a mini project using 68k microprocessor. I really want help to find reliable source code for pomodoro timer or at least simple timer with limit time. Can somebody help me with the website or something else to find the source code. Please help me as soon as possible.

I am currently trying to learn the Phaser framework and am having trouble with the procedural generation of platforms. It just isn't as smooth as I would like it to be. The source code is available here https://github.com/davidmather/Phaser var accelerationY; window.ondevicemotion = function(event) { accelerationY = event.accelerationIncludingGravity.y; } var jump; window.onclick = function(event) { jump = true; } var game = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.CANVAS, 'game'); var PhaserGame = function () { this.player = null; this.platforms = null; this…

Perhaps some of you could give me some feedback on your experience with screen recorders. I've not recorded any of my live games but would like to for personal reflection and to improve my strategy. I know Fraps is a popular software for capturing video but it's only available for Windows XP, Vista, and Windows 7. A friend has recommended Movavi and it seems that it has some extra features too such as video editing and recording live streams. Does anyone have experience with Movavi or any other video and screen recorders for Mac? I'm inexperienced with such software and would appreciate some preliminary advice before downloading.

I am student and i was asked to do a project about microprocessor. Can anybody suggest me about what kind of project can be done with microprocessor and how to do it. I hoping kindly please help me.

http://www.telegraph.co.uk/technology/2016/03/24/microsofts-teen-girl-ai-turns-into-a-hitler-loving-sex-robot-wit/ Big news Big news for me because I'm a programmer that's trying to branch his science skills too. Let me know if you find anymore like this. I want to be able to talk to these A.I.s and try to "hack" their thinking process. I can't believe I missed this opportunity. It was amazing. I am doing everything in my ability to creating something like this myself. The clock is counting down... 2020

Hi.. i want to submit my assignment next week so their for i need an android Project "Book Reader" or "Ebook Reader" not apk.. project folder of that. kindly if any one able to find share the links thank you.
