| Posted: 28 Jun 2020 08:36 AM PDT Sorry if this is the wrong sub for this. But yeah, do cars have brand-name CPUs from Intel or AMD? I just got curious, because I was thinking about it, and when it comes to futureproofing for vehicle-to-vehicle communications, they would want some decent hardware in there. But then again, I'm sure cars in the 80s and 90s had some Atari-grade CPUs to handle whatever KBs of data they had to process. [link] [comments]  |

| How do you ensure your team know about existing codebases and projects? Posted: 28 Jun 2020 05:52 AM PDT We have a lot of functionality, built over multiple languages and targeting different environments. There's a discovery problem where things that have already been made are often rewritten as people don't know there's a class that does it that can be ripped from elsewhere. How do you handle this situation in your teams? [link] [comments]  |
| Extratcing files through CMD, tell it to create and name a folder? Posted: 28 Jun 2020 02:35 PM PDT So I'm currently extracting all the game files for Detroit Become Human, I'm having to do it one by one by telling it to extract the model, then creating a new folder, naming the folder, and moving the files into it. Is there any way to possibly tell the CMD to create a folder with the name of the command, and to place the files in there? [link] [comments]  |

| If you were to start over, what route would you take? Posted: 28 Jun 2020 02:18 PM PDT If you were to start over, what language/framework/IDE would you use? So I grew up a programmer. Java, C++, PHP, and Python mainly. Been out of it for ~10 years. But I've missed it every day and am starting to get back into it as my daily hobby - specifically, for mobile app development. My natural inclination is to pick back up with Python and use one of the couple of packages out there, like Django, to make it friendly for mobile app development. However, the more I poke around, the more I see how many robust frameworks, IDEs, drag and drop "app creators", and everything in between there are, so perhaps just "sticking with why I knew" is not the best course of action. So my question to you all is, if you forgot all that you already knew and had to start over, what route would you take?? [link] [comments]  |
| node "nodeMailer" bot issue, bad logic I can't find is causing madness..looking for debug help Posted: 28 Jun 2020 10:16 PM PDT Hi all, I have a issue with a project I am working on.... it uses node.js and it updates a LED bar based on emails(by content in body atm, I plan on using it to light up LED's incrementally and color will reflect the content, so if i have a new work email it will pop up, and later I plan on making it so it only cares about unread emails..) and my only remaining issue is that the email bot is just losing its mind.... this is a copy of the terminal log I had : https://github.com/dylanpoll/EmailLightBar/blob/master/emailLEDbot/emailConnectTerminalLog ....if anyone can help me figure out why it keeps going through the loop despite satisfying the conditions I would appreciate it X/ node and .js aren't my strongest skill sets... The code for the email portion is : https://github.com/dylanpoll/EmailLightBar/blob/master/emailLEDbot/emailConnect.js if you find my stupidity X/ aside from that, everything else is done, the embedded system portion and the rest api portion and I left potential for hooking it up to a DB A link to the full repo is : https://github.com/dylanpoll/EmailLightBar [link] [comments]  |
| How would you debug a problem where network requests aren't reaching your Herokup app? Posted: 28 Jun 2020 04:36 PM PDT I built a device with an ESP8266 that sends small data packets to a Heroku server on command and checks for updates every ~5 seconds. This device worked fine for ~1.5 years, until it suddenly stopped working last week. Since the ESP8266 is basically a wifi chip, it is difficult to debug. That said, I don't believe the problem lies in the chip - I actually had two devices, and they were both stopped working at the same time. However, I updated my Heroku app with some basic code that shows when the last ping was, and it's clear that the ESP8266's requests are not reaching the server. But from the outside, the server seems to be working normally - testing ESP8266 endpoints with Postman result in anticipated behavior. I have not changed the environment recently (wifi password is unchanged, Herokup app is unchanged (except for the change noted above), the Heroku requests use a ****.herokuapp.com url so it's not an IP issue, router firmware is unchanged)... Any thoughts on how I could proceed to debug this? I anticipate that it could be something as simple as Heroku / Amazon recently having changed their firewall rules and blocking pings from my devices. Thanks in advance! [link] [comments]  |

| Generating Formatted Word Documents in C++ Posted: 28 Jun 2020 03:38 PM PDT This is my first time posting on reddit and might be the wrong sub; if so sorry in advance. I have been working on a program that generates word documents that takes user input for various names, dates and adresses and inserts those into word reports and forms. Using fstream, I have been able to write generate the reports but I can't make the words bold,add boxes around certain sections or change font. Is it possible to do this? [link] [comments]  |
| Posted: 28 Jun 2020 05:10 AM PDT Raspberry Pi 4 with 4Gb Ram is definitely best raspberry pi, but I am limited in terms of money, so I can't exactly afford one. So out of these 3 options: 1) Raspberry Pi 4 2Gb Ram 2) Raspberry Pi 3B+ 3) Raspberry Pi 3B Which one is the best? I will probably try to use it for ethical hacking, but other uses are also important. Which one should I buy? [link] [comments]  |
| What's the best source for learning about GIT/version control? Posted: 28 Jun 2020 02:04 PM PDT I'm having a hard time understanding different concepts (branches, master/slave, head, etc.) and it's getting awkward because of my job. Is there a good source that breaks down these things and explain them in detail? [link] [comments]  |
| Any good books/resources on clickstream analytics? Posted: 28 Jun 2020 02:03 PM PDT I'm trying to design an architecture at work revolving around clickstream. In particular tracking the journey of a user through different engagements to determine what things yield the most successful results. In particular, I want to learn more about how systems like these are designed. I assume it involves a lot with data warehousing, sessionization, cookies, etc. I want to learn! Thanks.

| Implementing sloped floors in a raycaster engine Posted: 28 Jun 2020 10:13 AM PDT So, I have finished implementing pretty standard raycaster engine. There are quite a few good tutorials online and piecing it all together I was able to understand the technique relatively well to build my own engine. Now, there is one thing that is not covered by any of the tutorials - just how to make sloped floors :) There is "Build Engine" which does support sloped floors and a few other interesting features, but as far as I know it isn't strictly a raycaster engine. So, I was wondering if there are any techniques or even "hacks" that can be used to implement actual sloped floors or some kind of imitation that would look relatively realistic. One solution I found (which doesn't work for me unfortunately) is the way sloped floors / stairs were implemented in Zero Tolerance on Sega Genesis. They simply draw both floor and ceiling in solid color and only draw the walls in a sloped manner to create the illusion. Given low resolution of the system and lack of texturing (just solid colors) it looks quite convincing. But it doesn't work for me because I use properly textured floors and ceilings, so it has to be rendered correctly with texture mapping. I would appreciate any ideas! :) [link] [comments]  |
| What is the difference between CI and Test Automation? Posted: 28 Jun 2020 05:08 AM PDT Those terms are confusing to me:
Is test automation just one part of a continuous integration pipeline, meaning in practice that before a branch is merged you can see if all tests succeeded / which went wrong? Some simple questions:

| Posted: 28 Jun 2020 01:23 PM PDT I am looking for an alternate revenue stream to Ads. If I know certain user's topics of interest, I think providing relevant news/blogs in the feed could be a potentially revenue stream. I know many blog/news sites profit from Ads. Do any offer payment for publicity/referral? E.g. Ads but for sponsored news/blogs/headlines. You know how Robinhood has that relevant news section? Is there an API I can use for this? Does it pay?

| Android Studio, Java - Options menu only opens in MainActivity Posted: 28 Jun 2020 12:03 PM PDT Hey everyone. Sorry for the text dump, but I'm having a really hard time figuring out what I might be doing wrong here... I hope this is the place to find out! I'm having an issue trying to open a drop down menu in any activity other than my main activity right now. The three dots in the top right corner that I can click to open the menu in MainActivity still show up in PieChartActivity, but clicking them does nothing. Also, it might be important to note that I'm using the drop down menu in the first activity to navigate to the second activity. Then in that second activity, clicking the three dots in the corner doesn't open that activity's menu. Typing out the code would take forever, and pasting it here makes it almost unreadable, so here's a Stack Overflow link where I've pasted the important code. https://stackoverflow.com/questions/62601735/android-studio-options-menu-only-opens-in-main-activity [link] [comments]  |
| What is the best language to learn foe mobile application development (preferably iOS) Posted: 28 Jun 2020 11:38 AM PDT What is the best language to learn for mobile app development (preferably ios) Over the past 5 years i've studied through courses touching on C# and C++ however, i've completely stopped any kinds of programming and want to get back into it. I want to start developing basic applications and hopefully work my way to basic game applications (card games). What language should I start learning? I don't own a mac so I can't develop in Swift [link] [comments]  |
| Questions about JavaScript as a language Posted: 28 Jun 2020 11:05 AM PDT I have a few questions about JavaScript. Over the years, I've read possibly hundreds of different web pages (plus textbook pages) on JavaScript itself, why | why not, good | bad of JS, JS compared to whatever, and etc., so I know general stuff around JS; what I want to know instead of the information readily available online is:
If this has been answered already, links to previously published material are welcome. Edited slightly to clarify point of question. [link] [comments]  |
| Finding memory leak in native lib Posted: 28 Jun 2020 06:28 AM PDT I'm upgrading the version of a vendor-provided Java / JNI library we use. The new version seems to have a pretty terrible memory leak (over the course of a day it'll eat up all the RAM on the box, ~30gb). The vendor isn't being particularly useful and I need to do some more investigation as to where this is coming from. I've run the app with jemalloc as per here https://technology.blog.gov.uk/2015/12/11/using-jemalloc-to-get-to-the-bottom-of-a-memory-leak/ , and this showed growth in one method from the lib. I also tried async-profiler to produce a flame graph and while the same method showed up, its % on there was much less significant than on the graph produced by jemalloc/jeprof. As might be apparent, I'm not entirely sure what either of the graphs show. Do they represent memory usage, or just the number of calls to 'malloc'? Does a particularly high % (~40-50, and growing over time) on the jemalloc graph necessarily mean that's where the leak is coming from? Since I know that if I leave the app running for 6+ hours and there'll be a significant amount of bad memory allocated, is there a better way to analyze the memory allocation of the app and see where it's going? And final question, we run our app with -Xmx8192, so if it's is showing up as using far in excess of 8GB does that mean this is an 'off-heap' memory leak? Any other tips greatly appreciated. Thanks [link] [comments]  |
| Unable to fetch from local database Posted: 28 Jun 2020 09:10 AM PDT Hope you all are doing well and are safe. So I was working on an application where I had to use the sign in functionality using standard procedure..., now I am a bit stuck on how do I continue my path... Basically what has happened is that I have created one User for an application but now I am having trouble to fetch is using my local database.. but now that I am trying to send it back to the front-end it is not getting fetched. Here are my codes for it.. Config Files.... //config.js // .env Now What I feel is happening is that my database is getting saved, but somehow its not getting fetched. This is the message I get when I tried to re-create the user And when I try to login this is what happens.. enter image description here Also when I am trying to fetch API to the router following errors were seen Null- when I tried to print the User User {Model} when I tried the print the whole User Database... Here are my user Files //userModel //userRoutes //userActions //userConstants //userReducers //store //server Once again I feel that somehow that User is getting saved to the localdb but the problem has been in fetching the API the reason being I am not able to fetch it. Thanks to the Kind Soul in Advance :) [link] [comments]  |
