    A request

    Posted: 26 Jul 2020 03:48 PM PDT

    Hi! This might not be the right place to come for this but I need any help I can get. My elder brother is well versed in javascript and for his birthday I wanted to sew a sleeping related code into a pillowcase for a present. I have my design planned out but I can't really code... I wanted the present to be a surprise so I figured I'd ask here. I need a couple lines of code that have commands such as "lie down", "dream of puppies", "get rickrolled by the sandman", "visit an alternate dimension", "you awaken feeling rested" & anything else you think you might wanna add. I don't know how demanding this would be so any help would be appreciated!

    TL;DR: I need a plausible code about sleeping/dreaming. Thanks!

    How big is the full installation of Cygwin?

    Posted: 26 Jul 2020 09:41 PM PDT

    I want to scale down from a full IDE to just VS Code. MinGW is giving me trouble and I want to make sure I have all of the possibly needed functionality until I get a better computer.

    When does your credit card bank returns your FName/LName to the merchant?

    Posted: 26 Jul 2020 09:37 PM PDT

    I ask this question in the programming forum because programmers exactly know what happens in each step, this question is precise/specific, please pay attention to my question
    When you put your info(credit number, expiration, and 3 digits), some merchants don't charge your card right away, they just send your info to Probably fedwire, and he says the card is valid, I don't know if it returns your FName, LName too at that step without charging your card or not? and that's my question, in that window that your card just being validated that exists(which again not all merchants delay the actual charge on your card!, some do it right away), till the actual charge happens, does Fedwire sends out my actual Fname and Lname to the merchant or not, or it waits until a request for payment come through?
    the reason I am asking this is because I was trying to mask my info by using privacy.com service, and I mistakenly put down my own credit card, the second I noticed I locked my card and then transaction happened after that, and it got denied, I want to know if the merchant has access to my personal info right now?

    Fact:
    No matter what you put for your Fname, and LName, I know for the fact, if the transaction happens your bank will return your real FName/LName to the merchant

    Is this the way? Copying front end ? Lol?

    Posted: 26 Jul 2020 09:02 PM PDT

    So I'm not a front end god and don't want to spend hours on each page. So I go online and get tutorials and copy their code, debug, and boom less than 5 min I got a beautiful front end. This is ok right?

    I'm trying to code a discord bot, and something came up

    Posted: 26 Jul 2020 08:37 PM PDT

    Here's my code:

    const Discord = require('discord.js');
    const Client = new Discord.Client();
    const prefix = 'm!';

    Client.once('ready', () => {
    console.log('Merlin is online!')
    console.log("start")
    });
    client.on('message', message =>{
    if(!message.content.startsWith(prefix) || message.author.bot) return;
    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();
    if(command == 'Hello'){
    message.channel.send('Ah, Hello.');
    }
    });
    Client.login('insert token here');

    Here's the problems:

    ReferenceError: client is not defined

    at Object.<anonymous> (C:\Users\li_gu\OneDrive\Merlin\main.js:14:1)

    Please help me understand Docker and GitLab

    Posted: 26 Jul 2020 08:06 PM PDT

    I am new to the above. I am used to Git but on as a team basis so my knowledge is quite limited and as for Docker it is completely alien, and so are node js and express js which I am learning now.

    My temp job requires me to know how to use this.

    I desperately need to have some resources or tutorial to guide me on the above.

    The Gitlab and Docker need to work with c#, Node.js and express.js

    Thanks a million.

    How to deal with trauma left by job

    Posted: 26 Jul 2020 04:13 PM PDT

    I used to really enjoy programming, but a job left a trauma of sorts. Now if i try to program again, the negative associations put me off immediately and i stop.

    It's been 4 months since i quit my job.

    I don't know if i should power through it and just code (but worried this might deepen the wound), or wait it out another year or so for the memories to fade (will they ever?) before attempting again.

    Thoughts?

    Optimal data design for a Note taking app

    Posted: 26 Jul 2020 07:41 PM PDT

    I have an app that users will use to write a lot on the front end and am worried that the database writes will get crazy (am using Firebase on the backend). I'm using a lodash debounce function so its technically a write after a user stops for a given interval (1200 ms) rather than on each character they type.

    This works but the experience can sometimes be a bit...laggy/janky. I was wondering if there is a more optimal/robust way to design this keeping costs down but also giving the user a smooth experience.

    How do you go about reinventing yourself as a developer?

    Posted: 25 Jul 2020 10:31 PM PDT

    Hoping this doesn't end up being too rambling - I've been in webdev for about 4 years now. Prior to that, I did a stint working on an ML platform for a couple years, which was basically my first professional gig. What I am learning is that while it's a reasonable sector to get comfortable in, I'm bored out of my mind and it just isn't the way I want to deploy my skillset.

    But, of course, you're pigeonholed basically the moment you step out of the classroom based on where you happen to have picked up an internship or where you managed to land that first job after a desperate few months where you'd basically take anything. So I'm many years deep into being a full-stack generalist and all lateral moves available to me must involve those skills. Let's say for the sake of argument that I don't really care about making a lateral move: I want to start over. Let's pretend that my passion is instead something in the realm of operating systems (it isn't), but I have very little experience and am minimally conversant in most of the tech involved. This is basically starting from scratch.

    So, is that even a thing? Are we talking about a 33 year old going back and doing an unpaid internship at Microsoft or something? Or do I just yield to the pigeonhole?

    What is it about Doom that allows it to run on pretty much everything?

    Posted: 26 Jul 2020 05:02 PM PDT

    After seeing this post and having seen many "Running Doom on (insert unexpected thing)" posts, I'm curious.

    Is there something special about Doom and/or id Software's engine that allows to run on pretty much everything, whereas most other game engines don't? I know Carmack is a highly respected and talented programmer, so is the idTech engine just THAT good?

    Or is it arbitrary and could be done with any game, it's just the meme to run Doom instead of other games?

    So where can I continue learning es6+?

    Posted: 26 Jul 2020 04:09 PM PDT

    I am 100% self taught from online resources and personal research. I taught myself all of Java 8 and most of Java 11 last year and have some decent personal experience using Spring Framework. I would like to learn JavaScript now. I have been using this course on udemy: https://www.udemy.com/share/101W9CAEEeeVhUQHQH/

    Im 14 sections in now, and while the course has been a great stepping stone into the world of JS, it's given me enough knowledge to know now that I'm learning extremely outdated content - the course is taught using es5 - no notions of classes or inheritance, everything is all still using the prototype chain. I need a good reference on the latest JavaScript version.

    Being as that I'm still a JS noob, I'm not sure how 'up to date' the material I learn should be ? Is ES6 enough? Seeing as how JS is up to ES9 now, where am I to begin?

    Any links to video courses would be appreciated. Free is great, but I'm willing to pay a reasonable amount for a resource with easy to understand information and up to date content. Most preferably a one-stop-stop for learning JS(ES6+) from beginner to advanced and some projects that can put me in real world frameworks and API integration.

    Hi there! I'm quite new to this entire App programming and i don't know how to manage the back end of my app. I'm using flutter and i can't find anything on how to make phones talk to each other, sending data back and forth. by that i don't mean talking to a cloud but litterally talking to each other. Can someone help me/give me a hint or a library or something? Any help would be appreciated, no matter if it's a swift tutorial link or whatever. Thank you very much!

    How do I interface with machines?

    Posted: 26 Jul 2020 07:57 AM PDT

    Hello,

    So I had a relatively quick question. You know how some people will "hack" airplane games or they'll make an ai play a game or whatever? My question is how do they actually access the controls in machines like this. If I made an ai to play super Mario I would need feedback from the Nintendo console as to where monsters are or where a staircase is (i.e. is there a block in front of me, if so I must jump). What are actual libraries used for this or how is interfacing with computer in machines (whether that's a console or just a computer in a digital clock) actually done? Thanks!

    Want to program a thing, what lenguage should I use?

    Posted: 26 Jul 2020 01:44 PM PDT

    I'm new to coding, but I want to program centran tools that would make my life so much easier. One of them is a tool who could sort pictures by their color (the most prominent in a picture) and put them in a discord chat (ie; the most prominent color is #000900 so it uploads it to a chat named 000900). I think phyton would be the best one, but I'm not sure.

    [PHP][MySQL] Would saving images to site directory without indexing in database 'bite' me back one day?

    Posted: 26 Jul 2020 12:02 PM PDT

    When it comes to filing in my web application,the hierarchy is only 2 levels. Each [client]-folder can have multiple [invoice]-folders and each invoice could have multiple images stored in it.

    Primary keys for the clients and invoices are stored in the database. So, accessing these folders is done very directly using the directory path.

    Whenever I upload new images, I use the following:

    if(!is_dir($file_path_client_invoice)){ mkdir($file_path_client_invoice,0777,true); }

    After creating the folders, images are compressed and uploaded in my target path. So far no issues.

    My issue or my doubts stem from that fact that I would like to keep track of the total size of the [clients] directory. As far as I know, the only way of computing the size of a directory along with all of the sub-directories within it, is to actually loop through the whole thing.

    I'm already using this piece:

    function folderSize ($dir) { $size = 0; foreach (glob(rtrim($dir, '/').'/*', GLOB_NOSORT) as $each) { $size += is_file($each) ? filesize($each) : folderSize($each); } return $size; }

    It does exactly what I described above. Currently with 50 demo-clients and 100 or so images it is doing just fine. But I'm afraid that this method would not be able to maintain its integrity with an expanding clients base. What are your concerns and expectations in regard to this method?

    Alternatively, I could create an [images] table in my db, and with every image uploaded, I could pass on the image name/address and size to the database. This way I could always query the sum() without the need to actually loop in my site directory. A shortcoming of this method is the need to play in both fields, site directory and db. Every time I delete an image, I would need to delete the respective row in my db.

    I appreciate your time and I'm very interested in your views on this topic.

    Is it possible to create a web page using an XML file?

    Posted: 26 Jul 2020 11:59 AM PDT

    Hey everyone, I apologize in advance if I'm posting this in the wrong subreddit, I have no idea how this stuff works.

    I have an XML file that's from a site that was closed (Real Life Villains Wiki) and I've been searching everywhere for a program where I could view an XML file coherently, but didn't found anything.

    So, I just wanna know if it's possible to create a web page or if I should give up and try to read what I have using Notepad++.

    Open Source Machine Learning Library. Team up.

    Posted: 26 Jul 2020 10:20 AM PDT

    Join Us ! Hey Everyone ! This is Faraz I am a 2nd Year computer science student and I am a Machine learning enthusiast. I am learning ML and also wanted to improve my python skills so I decided to start an Open-Source project along with a friend. I have started an open source project for building machine learning library in which we will code machine learning algorithms, evaluation metrics from scratch. But unfortunately we don't have friends who can join the project as a contributor and member. We are looking for coders, beginners/intermediate, like-minded people who want to contribute to a machine learning project and join us as a maintainer.

    We are beginners looking for beginners to join hands and work as a team. It's an open source project so obviously there is no glory in it but we will definitely get to learn something about ML,python packaging, testing. It will be a great experience to learn from like-minded people. The library is currently a private repository but we will make it public once we have have everything sorted.

    If you are interested please reply to this or you can email me at : farazkhan138@gmail.com.

    Problems programing my PB-110 in BASIC

    Posted: 26 Jul 2020 09:41 AM PDT

    Hi

    Since a few days I try to get a CASIO PB-110 working, that I found at a second-hand shop. This is a pocket calculator that can be programmed with BASIC (I tested all functions and they work, only when I try to program he crashes).

    I'm not new to coding but I never worked with something like this. I need to assign steps to a memory place, then choose a program slot and then can I write some code. The problem now is that every time when I write my first line of code the calculator crashes or freezes and I don't know what I am doing wrong. I searched for a long time on the internet but could not find any tutorials or manuals. I found the manual for the PB-100 which is a great help, it is not that big difference to the PB-110.

    Now my problem, as I said, I'm not used to that art of programing (steps, memory etc.) the calculator is way older than me, and now I hope that I find someone here that knows how to program it.

    ​

    My inputs:

    DEFM 1 (defines memory place and gives me a amount of steps to use)

    10 INPUT A,B (first line, wait for input A and B)

    When I hit EXE (enter key on the calculator) the screen goes blank and it stays that way.

    ​

    Does someone know how I need to do it, or does that mean that the calculator is damaged?

    Read flat file and swap values based on SQL table?

    Posted: 26 Jul 2020 09:24 AM PDT

    I have a folder where flat files are sent. They are basically CSVs, but delimited by ~. Example would be this...

    Job1 tilde Walmart AA battery tilde UPC tilde Code

    Job1 tilde Walmart AAA battery tilde UPC tilde Code

    Job2 tilde Walmart C battery tilde UPC tilde Code

    Code is a number that signifies equivalence. So if a job specifies needing a walmart AA, and there aren't any in stock, I want it to look at what's in stock that shared the equivalence code. So then i can replace the tool with another brand that is basically the same thing, and have the UPC changed to that equivalent thing.

    This is just an example using something easy to understand.

    So when a flat file comes in, I need to look in the flat file line by line...i need to grab the UPC, look to see if it's in an SQL table (could make it excel, but table not static), if it is in the table the line can be left alone and move onto next line.

    If the UPC is not in the table, I need to then grab the equivalence code from that line and search the SQL table for that. If I get a hit, I need to grab the UPC of that equal item and overwrite the UPC in that line of the flat file.

    After it makes the changes, if any, I'd like the file to go to another folder.

    I looked into doing in python but I don't know how to accomplish the replacement logic.

    I don't care if it is paid software, or some strange python module/tutorial, or an excel powerquery VBA thing... I just need some guidance because I haven't been able to piece together a plan.

    Thanks for your time

    EDIT: also, I need to log the lines that get swapped. Literally just have it copy a whole line if it was changed and dump somewhere. I don't need to capture the line as it was before it was changed. Whatever it is after is fine.

    I have found a partner who can help me with bringing a project which is 70% done, to life.

    Posted: 26 Jul 2020 01:53 AM PDT

    He is from another country and I am afraid he could leak code or steal the source code. He has a good public image, but still, the project I have is very important and took me three years to reach 70%. How can I safely start working with him? I am so afraid he will make the source code public or take it and make it his own, etc.

    Why is the NP graph like this? What’s NP-Hard? Why isn’t it inside the circle of NP?

    Posted: 25 Jul 2020 11:32 PM PDT

    Problem L is NP-complete if:

    1) L is in NP (Any given solution for NP-complete problems can be verified quickly, but there is no efficient known solution).

    2) Every problem in NP is reducible to L in polynomial time.

    Android Studio, java or kotlin is fine, Twitter Api Oauth1 authorization could not authenticate you, suspect oauth signature

    Posted: 26 Jul 2020 02:54 AM PDT

    I'm trying to use Twitter api, but I just can't bypass Twitter authorization Oauth1.0, the problem probably at oauth signature part

    The Twitter Api doc said to get oauth signature, I need to make base string which = (REST request) +(base url without query and hash parameters) +( all parameters) then percent encode it and I got the base string, and I compare it with example from doc format and it should be ok, then getting the key which is consumer key +"&" + token key, then use Hmac_sha1 algorithm to change the key and get the Hmac_sha1 byte[]

    After getting base string and byte array, use base64 to encode it into string and you get oauth signature, but I keep getting error 401 code 31 could not authenticate you

    I check it using postman restApi and postman can generate oauth signature automatically without issue, and if i copy the string authorization timestamp, nonce, and oauth signature from postman and hardcore it to my header authorization the request work fine without error, are there step that I miss? Or there are already automatic Oauth1.0 generator libraries that work?

    The oauth signature method are like this

    private String encryptUsingHmacSHA1(String input) {

     String secret = new StringBuilder().append(encode(consumerSecret)).append("&").append(encode(tokenSecret)).toString(); byte[] keyBytes = secret.getBytes(StandardCharsets.UTF_8); SecretKey key = new SecretKeySpec(keyBytes, HMAC_SHA1); Mac mac; try { mac = Mac.getInstance(HMAC_SHA1); mac.init(key); } catch (NoSuchAlgorithmException | InvalidKeyException e) { e.printStackTrace(); return null; } byte[] signatureBytes = mac.doFinal(input.getBytes(StandardCharsets.UTF_8)); return new String(Base64.getEncoder().encode(signatureBytes)); }
