| What are other really good places for high quality programming discussion? Posted: 24 Feb 2021 02:44 PM PST This sub is phenomenal. It's a shame covid drove everyone to reddit.com and now programming discussion is kind of drowned out on Reddit more generally. Are there any places that kept that old Reddit spirit of meming XKCD and cracking nerdy jokes, while also posting genuinely insightful and groundbreaking links about software news?

| Have you ever experienced panic attacks caused by work issues too? Posted: 24 Feb 2021 08:12 PM PST I'm thinking on mental health lately. I've suffered this before, not always work related, but my mind was a mess and it indirectly affected my work as software developer. What techniques do you recommend to prevent or even solve a panic attack on spot? I would recommend to practice breathing techniques, but maybe you have better tools. [link] [comments] |
| What is it called when I use an integer to describe multiple options? Posted: 24 Feb 2021 06:27 PM PST I have no clue how to describe that search engine friendly. What I am referring to is something I found with permissions on Linux on my workstation and also in one of the old Quake3 server settings. What is that *thing* called, and if it doesn't have a proper name, how would I go about implementing this is pseudocode? (The examples below got longer than expected so my second question right away here: My guess is that this makes it a lot faster for low level languages to check an 'array of booleans'. Is that assumption correct?) Thanks in advance! The *thing*: Lets say I want to invite my friends to a party after Covid (lets just pretend I had enough friends to make this example (: ) My (imaginary) friends: (1) Ada If I want my program to send out invites but I am also pretty lazy, I could give it an integer which is the sum of the 2^(number) for all my options. As I understand, I can imagine a byte and simply put a 1 for the peeps I want to hang out with a 0 for the ones I want to avoid: Ada, Alan and John: [00000111] -> integer: 7 (=1+2+4) On linux I saw this being done with permissions: (1) exec So to give permissions you can use 0 -> nothing [link] [comments] |
| Extracting a .DAT file from a game. Posted: 24 Feb 2021 10:36 PM PST Hello, to begin, I'll give a bit of context, I know barely ANYTHING about programming, but I do know how universal .dat files and the .dat file associated with said game, (It's the DOS/Win 95 port) Is the biggest file in the directory, at 506 MB, the folder being about 512. I know finding the original program would be a stroke of dumb luck, but I'm hoping I can somewhat find a program that is able to extract the files successfully, At the moment I've got a Hex editor open, and I don't want to post any of the numbers here yet, in case they end up being the wrong ones.

| Can't seem to figure out how to approach this question Posted: 25 Feb 2021 01:29 AM PST Can someone help me break this down and which commands to use? I am really new at r coding and don't really understand how to do this. Suppose that the current stock price of CompanyX is $100. Assume that each day, the stock price of CompanyX could go up $1, or go down by $1, or stay constant, all with equal probability. In other words, each day, the change to the stock price is a random draw from c(1,0,-1). You are asked to analyze the returns of your investment in 60 days under different trading strategies using R simulations.

| Posted: 25 Feb 2021 01:11 AM PST I'm still a newbie when it comes to computer software, and I had 2 goals/apps in mind that I imagine should be simple enough to complete as my first official projects 1) basic block-based notes app (refer to Google keep) 2) simple tic tac toe game/website I'm assuming both can be done fully, and well with the same language (integration is different?) If so which one(s) Thanks for your time, attention, & efforts :) [link] [comments] |

| Which of these Tenancy models is better? Posted: 24 Feb 2021 06:33 PM PST I'm architecting a tenancy model and I'd love to here your thoughts. In one version, I have separate folders that represent each tenant, and each folder\tenant has it's own SQLite database. In the other version, all tenants use the same MSSQL or Postgres Database. From a schema perspective, it's easier much easier to keep each tenants data separate, because they will ultimately have unique schemas. My really question is what are your thoughts on what would perform better under the same stress? [link] [comments] |
| Minecraft nether fortress/bastion remnant generation Posted: 25 Feb 2021 12:23 AM PST You might or might not have heard that minecraft speedrunning is quite popular these days. And I was wondering since nothing is truly random, if there is a way to determine rough estimation for possible nether fortress generation with the knowledge of the exact location of bastion remnant. It is known that these two structures affect each other, since only one can spawn per "quadrant (roughly a 400 block area with a small divider between each "quadrant")". I should mention one rule that is important: you cannot know the seed of the world during the run. Here is the code - this is not an official minecraft code, but it is pretty close to the original (it is a finder for all sorts of minecraft features). This is quite a school project of an question, so I understand if no one wants to do it, but I would greatly appreciate your help. [link] [comments] |

| [Android] How to save a text file with chooser? Posted: 25 Feb 2021 12:03 AM PST I'm trying to save a text file to a directory the user chooses. I can save a file with Intent.createChooser() but can't find out how to save the data to the file after it's created. Any help would be much appreciated.

| about IHP and Redwood JS stickers Posted: 25 Feb 2021 12:00 AM PST Do IHP and Redwood send stickers to our address for free actually?? Like, are the delivery and rest charges also zero?? I want to confirm whether the entire thing is fully free or not. [link] [comments] |
| How to stay healthy as a programmer? Posted: 24 Feb 2021 02:51 AM PST I've started working remotely as a full time programmer for some weeks now, and noticed that I haven't being paying as much attention to my health as I did before. How do you think I can achieve a healthier work-life balance? EDIT: Thank you all for your comments, they are really helpful! [link] [comments] |
| Updating user data via PUT API call Posted: 24 Feb 2021 11:03 PM PST I am new to working with API and am not sure how to handle the following: I want to implement a PUT call to update user data(firstname, lastname, ..) Currently i call the GET call to get the users data. After that i check the user input and if it is not null than i set that value for the user i got via the GET API call. And here is what i am not sure if there maybe is another way to do this? Because i check all user inputs != null since the user maybe updates only one field. If it is null i take the value which the user already has. Is there any other way to do this? I am using a Java Springboot application with feign. [link] [comments] |
| Counting Operations - How many operators in a nested loop? Posted: 24 Feb 2021 10:05 PM PST I am currently doing a personal project on Big O, and how we can classify different algorithms using linear equations and so on. And since for this school project I want to put a heavy emphasis on what we learnt during class to bump my mark (quadratics and so on), finding how I can use math to find the Big O might be nice. From what I learnt, I start by counting the number of operators in our code. Then, depending on its time complexity, I would have to create an equation which satisfies our algorithm; for instance, if I had an algorithm that was O(n), my equation would be similar to y = mx+b. That's really easy, but with quadratics or algorithms with nested loops, it's harder... Let's say I have the following code... I know this algorithm is O(n^2) and I also know it's bad practice to notate O(n^2) as O(n^2+ax+b) or O(n) as O(mx+b), but how can I represent this algorithm with a quadratic equation (ex x^2 + ax + b)? I know for a fact that I have two constants (the two assignment operators in line 3 and 5), but would the operator found in "int j = 0" also be considered constant or not? Since this is a nested loop, j = 0 would have to be run again everytime the second loop is being run, right? With O(n) equations, it's pretty simple since I can easily recongnize what operators are constants and coefficients, a.k.a. what operators are or not affected by n. Any help on how I can notate the printAllPairs() algorithm as a quadratic equation? Sorry if it seem may seem easy for y'all, but a fellow high schooler needs help here. [link] [comments] |
| Posted: 24 Feb 2021 09:59 PM PST Hi can someone help me how to do MAC address multicasting just like UDP multicasting and i am using RAW socket with MAC address and interface name for communication. I have already programmed a MAC address communication using RAW and able to send a string of charecters and structure between 2 different PC's but now i need help in how to do multicast using the same idea.

| How would you build this? (Mobile app) Posted: 24 Feb 2021 09:33 PM PST I'm curious like technology wise/fastest implementation/economical. I come from the web dev side and trying to make something "for mobile" seems hacky if it's not coming directly from an app store whether by native or through something like React Native. I usually do PWA that works for me but to a "lay person" that's not technical/just expects it to work... seems off to be like "go to this site and add this to your home screen". These are the requirements pretty basic. This is not a job or something just something someone posted in a forum that they wished they had.

| Do SAAS companies offer early access to new features? Posted: 24 Feb 2021 02:05 PM PST Do you generally see that SAAS Companies allow early access to a redesigned feature? Or do companies just provide documentation, then switch features for all users at the same time? I have definitely seen both scenarios, but with the large number of companies, I'm curious on what others have seen. [link] [comments] |

| Posted: 24 Feb 2021 01:50 PM PST I've been learning about CRC-32 and understand both the naive and Sarwate algorithms. But I'm confused about endianness here. I mean, I see how endianness is relevant and all. But the polynomials 0x04c11db7 (BE) and 0xedb88320 (LE) of the IEEE 802.3 standard are opposites if you reverse them bit-by-bit. On the other hand, I keep reading (fig1, fig2) that endianness only applies to bytes within a word and that bits don't really have endianness. So shouldn't the LE version of 0x04c11db7 be 0xb71dc104 (byte order changed, bytes themselves the same) instead of 0xedb88320? [link] [comments] |
| How do I compile this CPP program (Kinect Azure) Posted: 24 Feb 2021 02:14 PM PST Hi, I have a kinect azure and I want to try out a few programs to make modifications. I am primarily a python programmer and I have worked with C several years back, but I need something simple to get this program working: https://github.com/microsoft/Azure-Kinect-Sensor-SDK/tree/master/tests/Calibration The SDK that has the header files is here: http://download.microsoft.com/download/1/9/8/198048e8-63f2-45c6-8f96-1fd541d1b4bc/Azure%20Kinect%20SDK%201.2.0.msi What I have done so far: Downloaded the SDK, installed MinGW and tried to compile the program. I am having issues with the path to the header files in the SDK. What do I need to do to compile this? I would really appreciate some help. [link] [comments] |

| Career advice - feeling stagnant Posted: 24 Feb 2021 07:57 AM PST I graduated with a bachelor's in computer science two years ago and have been at the same job ever since. My concern is that this job has consistently, actively pushed me away from programming (despite my title being "programmer") to a degree where I know I've become a worse programmer over time. I want to go elsewhere but no longer have much confidence in the skills I developed as an undergrad. What would you recommend to help me rebuild confidence as a programmer? What would make me a desirable candidate for hire as a programmer? I'm looking for any suggestions: classes, certifications, general skills that are highly sought after, etc. Thank you in advance for your help! [link] [comments] |
