| Could aliens reverse engineer TCP/IP? Posted: 12 May 2020 12:42 PM PDT Sorry for the off-the-wall question. It's for a story I'm writing. The aliens are about as advanced as we were the 50s. They know English but don't know our protocols, algorithms, etc. They receive a stream of data in TCP/IP format. How difficult would it be for them to make sense of it and decode it?

| How long did it take you to eventually not have as many bugs to fix on your programs? Posted: 12 May 2020 08:20 PM PDT I remember when I was interning I would constantly debug things the next day I came in and it would be the most annoying thing. Like I thought I would have gotten it down and each time the list of bugs I'd get from the QA would always stay the same. At the end of the internship I did get better though. But I'm just curious how long it took you to figure things out to where you don't have as many errors to debug? [link] [comments] | ||||||||
| Posted: 12 May 2020 08:38 PM PDT A very newbie question. I want to encrypt a password using 256 bit encryption and I was thinking if I can use the password as the private key to encrypt the password, that way we don't even know the private key to decrypt the password until the user enters it by themselves. Is the approach okay? and if it isn't please explain why. Thanks [link] [comments] | ||||||||
| Posted: 12 May 2020 07:52 PM PDT To make a long winded story short. Veteran with the GI Bill looking for colleges. I know California is the best for internships and job opportunities but only has a 22% chance for me to transfer from a community college to a UC 4 year. Where as Massachusetts has a garenteed transfer from community to UMass Amherst. Would going the Massachusetts route keep me from getting jobs? Could I still apply for jobs in California after I get my degree? Is there another option I haven't thought about? Highschool GPA was terrible (D student?) And I have no test scores.

| Need to build a cross platform app, but don't have MacOS Posted: 12 May 2020 06:42 AM PDT Hi. I'm building an application with flutter, since it needs to run on both Android and iOS. It does not require anything native, so I can also deploy it as a website. Unfortunately, I don't have a macbook. I can however get an iPhone on test on. I considered: 1) Making a responsive website and simply using a webview which will require minimal platform specific changes to the code. But what about performance? Will it still be the same experience as an app? However, the client (and I) feel that a website is not the most convenient way. The users of this app will be opening it daily, a website (in their browser, without using webview) will be just inconvenient enough for them to not want to use it. What are my options? 50% of the client base has an iPhone. Is finding a macbook the only way to make this happen? I use windows/manjaro. [link] [comments] | ||||||||
| Project Managers: Criteria for choosing a web tech stack? Posted: 12 May 2020 08:29 PM PDT TL;DRI'm curious to ask from those who have experience choosing the tech stacks for web projects. I'm not talking about personal or startup projects. If your priorities are to create a novel web application for a client (who doesn't specify the tech), how do you decide on your tech stack? More detailsI've read a lot of articles/discussions and they vary widely. It seems like a lot of people just base their choice on personal preference, or which technologies they're most familiar with. I'm more interested in a generalized approach of choosing the most appropriate stack that meets the project's needs. What questions guide your decision? Some that might come to mind are:

| Best place to discuss bugs about iOS safari? Posted: 12 May 2020 08:17 PM PDT I believe I have found a bug, but it could be intentional and I'm having a hard time finding more information on the topic, is there a decent place to discuss this kind of thing? I submitted the information to https://feedbackassistant.apple.com/ but it would be nice to have a discussion about it instead of just pushing feedback.

| How do you explain what code/functions are in terms of electricity Posted: 12 May 2020 08:06 PM PDT This is probably that thing where you say a word several times until it doesn't make sense anymore... I can see a rigid circuit or set of logic gates and it works, electricity flows from a to b. This is not about FPGAs Just a weird thought, like can an ML model just become an operating system by learning to fire the right events... but a model seems to be one-directional doesn't just sit/can wait for changes and "go" I guess maybe it's as simple as the CPU has a bunch of gates and you can dynamically run electricity through them from the program after it gets compiled down to machine code... I did take an intro CS class where we had to make our own ALU based on limits/expected operations eg. addition. [link] [comments] | ||||||||
| Need help getting started in the right direction Posted: 12 May 2020 07:16 PM PDT Hey, Guys new here to get right to it I just don't know where to start or looking so I think it would be a great spot to start off this journey. The basics of what I'm trying to do is Eventually have an (API?) developed from information either extracted or using the credential to "Website A" in order to use that information on a website that would be eventually developed. How can I come about this? (I have the information and logins to everything just refraining from mentioning specifics) So basically is there a way to have (API?) on a website where it can access "Website A" to use that information on "New Website" as a "Catalog" to search for "Items"? Is this something that's possible? I do know this will eventually require some type of SQL. Sorry this all Fairly new to me and just need help being pointed in the right direction... (If you want to get specifics you can PM me and I can be a little more detailed) [link] [comments] | ||||||||

| Looking for software to write code/normal text Posted: 12 May 2020 05:55 PM PDT I have an online exam next week which I need to submit my solutions in a single PDF document. The exam will have some questions which are essay questions and require normal text, and some questions which are code-based questions. I'm looking for a piece of software which will allow for standard word processing and also code blocks. Effectively, something like creating a post where I can have a code block but also type normally. I just want the output to be a PDF. Any suggestions? :) [link] [comments] | ||||||||
| Confused about worst and best case complexity Posted: 12 May 2020 04:20 PM PDT Hi! A question popped up on a worksheet I was doing on complexity. It asked if the following was true or false: Ω(lg N) ⊆ Ω(1000 · N) My initial thoughts was "true, " since (looking at a graph with both) lg N is always "under" (within) 1000N. The answer said false though. I tried changing the coefficients, but I still found that eventually, since were assuming large large inputs, lg N will come out on the bottom. I know my conceptual understanding of complexity is very weak, so Id really appreciate if someone could give me an explanation. Thank you so much! [link] [comments] | ||||||||
| C# programming on Linux: would be this problematic for a fairly new programmer? Posted: 12 May 2020 04:01 PM PDT I've been making a recent attempt to migrate over to GNU/Linux for non-gaming purposes. I'm not experienced with Linux, but I am taking a class on it that uses Ubuntu. My programming skill is at best intermediate, where advanced would be a step before professional. In other words, I'm still fairly new to the process, so a lot of the jargon is difficult for me to decipher (hence the reason googling this question only confused me more.) Is there any reason I would have problems learning to program (in C#) on Linux? Would apps I developed only be fit for Linux, or would they be cross-platform by virtue of .NET? Would I be able to go from Win machines to my Linux machine without issue while working on the same app? [link] [comments] | ||||||||

| The most stupid project idea you can think of Posted: 12 May 2020 02:01 PM PDT So I'm not the most original thinker so I thought of asking here for help. I'm basically interested in implementing something, which at its core would be quite trivial, in a stupidly complicated way. Esoteric languages or assembly are just examples. I'm really looking forward to what you guys can come up with. I would prefer it to be doable in under 10k lines of code so I don't waste my whole life on it lol. An idea that came to my mind some time ago was to implement TETRIS in MIPS assembly, but it didn't really click with me so I just let it go. [link] [comments] | ||||||||

| How to make node.js application work on a webpage Posted: 12 May 2020 12:12 PM PDT Hi everyone, I'm working on my first personal coding project. It is a simple webpage with a single textfield and a "Go" button. The functionality I am trying to program is that users can input a URL, hit the Go button, and then my website will return some data scraped from that URL. For the data scraping functionality, I followed a Youtube tutorial and programmed it on Node.js (works as expected when I hardcode the URL and run it from command prompt). How can I get my Node.js application running on my webpage so that it receives the URL that the user inputs and can then respond with the appropriate scraped data? Thank you in advance for your help.

| OAuth 2: Permissions of third party services, that act on behalf of a user Posted: 12 May 2020 01:08 AM PDT Hi, I have a scenario, where OAuth is mandatory. The OAuth flow will be provided by Azure AD. There are three layers. A frontend with some services, a layer with third party services and a layer with data storage. Users should login into the frontend with an account and access the the third party services. So far so good. That should work with the standard OAuth Authorization Flow. The users should also have access to the data stored in the data layer, but through the third party services they gave permission to. The services will do some analysis and so on. I, as the data provider, need to know whether a client is allowed to access data of a certain user. A coworker had the idea to demand the user token and the service token, when protected data is requested. This sounds a little odd to me. I think the user should somehow give the third party service his permission to request data in his name. So I can expect only the service token, which contains the users permission. My problem here is that I can't think of a concrete solution for the user to give his permission to a third party service, since these won't have a frontend of their own. Is it possible (and good practice) that the frontend asks the user for permissions on behalf of the third party service and update the service's permissions at the OAuth provider?
