How do you turn a WEBP file Into JPG, PNG, GIF and BMP files. Those 3 are accepted on most websites but there is this one site that only does WEBP file and its very hard to convert. I generally save it in MSpaint to convert it but that does not always work. Is there another way to do it?

So, I am working as an Embedded software Engineer. Embedded systems typically are seen as a small computer that can programmed to do a specific task just like a router for example or a smart phone but many universities put Embedded systems under Electrical Engineering because of the hardware part. What do you think?

So, the idea comes down to developing an MMORPG that educates people about how hacking really works. It isn't like a regular MMORPG, but it copy's elements in some ways. In this case, the way this "game" works is the world you are navigating in, the webpages, is only explored through by finding bugs within the webpages to get to the next webpage. This could mean breaking into a password-protected admin page or finding ways to exploit the system to get passwords that allow you to access other parts of the website. The more websites you are able to access, the more "points" you get for doing so. There would also be a ranking system based on how long it takes you to ent…

today my pc was acting up(now on old laptop), I could not get into my emails, in the end tried to get in touch with yahoo by phone i got number online, there where 3 numbers each gave an engaged tone then cut me off, i then tried next number 08002796226 (yahoo email support?) this was answered straight away by indian "gentleman" within a minute he had control of my computer, said i had been hacked from canada, for security he wanted date of birth telephone number, then he started flicking through my systems, after 10 minutes he said they could sort it for 380pound, which i refused then he asked for 200 which i refused he dropped to 70quid, i told him he is yahoo support…

Hello! Android and entering floating point numbers. With inputType=numericDecimal Has anybody found any sensible solution to this madness.. ? Google has not done anything since at least 2009 AFAIK. This for instance http://stackoverflow.com/questions/12780125/soft-keyboard-with-comma-instead-of-dot-for-decimal-separator-in-android doesn't work on my Samsung Galaxy S5.. Tried input.setKeyListener(DigitsKeyListener.getInstance("0123456789.,")); and the only thing it did, changed "." (dot) key on keyboard, to ".-,+", but it's just visual (!), not having any impact on entered characters in text view field.. (still not able to enter comma character o…

Overview In this walkthrough you will build pieces of a blogging application. The walkthrough will not result in a fully functional blogging application, but instead it will use the blog classes to demonstrate code first’s features. You will: Define a set of classes to represent the entities for a blog — Blog, Post and Comment. Reference the Entity Framework code first assembly. Create a DbContext to manage the Blog classes and data access. Build a simple ASP.NET MVC 3 application that will let you view, add, edit and delete blogs. Creating the MVC ApplicationFor this demo, all of the code will live inside of an MVC 3 project so the first step will be to create that pr…

I know that Computer Science is challenging in college, but how challenging or difficult is it when you start working. For example I know medical school is brutal, but being a doctor is very easy. Is this true with Computer science,? ex. Computer Programer, Software developer, Software engineer etc. I don't have much experience with Computer Science, Im thinking about majoring in it. Is it something you learn very fast? And do the schools train you and prepare you well for the workforce. PLEASE ANSWER

So I applied to a job recently and was told I had to write a string calculator in php which would take as input a string "//[delimeter][delimeter2]\n" followed by a load of numbers separated by the delimeters for example //[***][,,,]\n1***3,,,2 The person I applied to claimed to be able to solve this by just adding all the numbers. But I don't think this is correct because the delimeter could contain numbers for instance //[*1*][,2,]\n*1*3,2,2 . Then I thought I don't actually know what the delimeter is because the string can take 1 delimeter too ie //[delimeter]\n so the above //[*1*][,2,]\n*1*3,2,2 delimeter could actually be *1*][,2, with the number being 1322. Is th…

Hi, I will start to the department of computer engineering. And i want to do something about my department before starting the school. Now i've almost finished c programming book. What should i do after that? Note: My school will start on 13th September. Thank you in advance

I saw this video online recently about building a radar respiratory rate monitor. Counting respirations in hospitals is a pain because there isn't anything on most dynamaps to measure respirations and it is normally done by eye which is no good if the patient breathes through their nose.

I am currently running windows 7 on my pc. However a lot of employers are looking for knowledge of the Linux command line. Considering buying a second pc is out of the question I was told it might be possible to partition my hard drive and install Linux on the partition. But I am scared of doing it because if it didn't work properly I would lose my copy of windows 7 and any files I have. Does anybody know how to do this?

This seems like a genuinely stupid idea to me, but I can't help but pose the question: could an algorithm be written to beat the game 2048? Remember, computer science is definitely not my area of expertise, so try not to be too hard on the n00b.

Hello everyone! I've written an article about the dangers of artificial intelligence. No, not the danger of intelligent robots rising up and killing us, but the way more real danger of countless humans getting unemployed. As i elaborate in the article, that could ruin our society and even our species, one way or another. And it could be way worse than it sounds given the problem of human overpopulation and the need to be solved. It is a four-part article. Whoever is aware of what artificial intelligence is can avoid reading the second one. At some points, what i write seems like a conspiracy theory. They are not; the more the research on artificial intelligence…

Please have a look at my proposal to use CSV as lightweight data-interchange format compared to JSON and XML. Multi-level nested CSV TDV.pdf (or) http://siara.cc/csv_ml Screenshot of reference implementation: The demo application (Java) can be download from: http://siara.cc/csv_ml/csv_ml_swing_demo-1.0.0.jar The proposed format is expected to: save storage space (about 50% compared to JSON and 60-70% compared to XML) increase data transfer speeds be faster to parse compared to XML and JSON allow full schema definition and validation make schema definition simple, lightweight and in-line compared to DTD or XML Schema allow database binding be used in E…

I have my server installed with a self-signed ssl certificate. But this throws up a warning message on my browser when I try to access https. How do I generate a trusted cert?

So, I am beginning to apply for internships, and I was wondering what the difference between unpaid and paid internships in regards to environment and how effective they are on internships. Just give a general explanation, in those regards, of the differences between unpaid and paid internships.

It came with 6 cell battery. Battery was giving backup of maximum 2 hours. It worked fine for me until I was charging followed by fully discharging when I started always plugging and only discharging one time per day. Battery reduced backup time so much that I have to purchase new one. I wanted to purchase 12 cell battery but only 9 cell was available for this model so I went with that. I purchased in March 2015. When brought home, battery was working fine and giving backup of 3+ hours but battery used to show problem of "Caliberate" after some time and my fully discharging solved it but now this problem is not being solved. Please see recently checked status of the batte…

So, I began working on assignment recently, and it came to me how much information is on Wikipedia. Vast amounts of it are there and viewable by any user. However, the problem I find is there is information, but too much information. I want to find out something about a particular topic and want to see the information that relates to the question I have or simply want to satisfy curiosity. Another problem is Wikipedia is not always up-to-date. It relies on people being willing to go to the article and edit with proper information. Therefore, I propose a new type of Wikipedia software that solves those two major problems, in my opinion. The one idea involves using…

I'm new to computer programming but I thought I'd have a summer project now exams are finished. Which language is the best to develop a data input program for work. Which language would be the best to have a tick box for people people to click and submit once they've made an equipment check. The time gets logged on a database with time and date and there is an interface so other people at work can look and see what equipment has to be checked for that day. There is a computer system with multiple computers on the same account so it will have to support multiple users. I guess there should be a refresh button everytime someone wants to check. It also needs to have an input…

Hey there everyone. I want to know if there is any good software for animation. I would prefer the model which let me both edit drawings from MS paint or else had similar type of paint tools, as well as did it in the flash motion style where you do it frame by frame by frame. I know it takes longer but its way less complicated than trying to do the bone structure model type set up. I need something cheap that is not hundreds of dollars, however preferably not a torrent off the internet. Thanks to anyone who offers any assistance.

So I made a simple slot machine game. But I was wondering normally when you press spin you get the moving wheel what would be the best approach for that? I was thinking maybe a random gif. <?php $num1 = rand(1, 5);$num2 = rand(1, 5);$num3 = rand(1, 5); $num4 = rand(1, 5);$num5 = rand(1, 5);$num6 = rand(1, 5); $num7 = rand(1, 5);$num8 = rand(1, 5);$num9 = rand(1, 5); $result1 = $num1.' | '.$num2.' | '.$num3; $result2 = $num4.' | '.$num5.' | '.$num6; $result3 = $num7.' | '.$num8.' | '.$num9; // Read points from file $filename = 'points.txt'; $handle = fopen($filename, 'r'); $current = fread($handle, filesize($filename)); fclose($handle); if ( ($num1 == $num2 &amp…

Can anyone help me out with the basics of transactional memory and which kind of architecture supports it?

I was looking at a book called The Filter Bubble: What the Internet is Hiding From You, but it seems more opinion oriented rather than factual. The author said, "an engineer told me there are 57 signals that the site uses to figure out who you are." That's great, but I want to know more about how they do it. Let me talk to the engineer. I want something that will build up my knowledge from the basics. If you took classes, please recommend the textbooks used in your computer classes. I like buying the slightly outdated or international editions of textbooks for cheap. I'll just read the introductory chapters and anything that pertains to my interest. I can print out …

Sometimes when I am bored I write games like this one.
