| Hello guys, I have a question about where this b came from (C#) Posted: 08 Oct 2020 06:33 PM PDT [RESOLVED] Here is the code: char a = 'a'; char b = 'b'; char c = '\r'; char d = 'd'; string e = ("" + a + b + c + d); Console.WriteLine(e); Console.ReadLine(); And it somehow prints out this : > db db!!!!!! What???? I am so confused. Shouldn't it be just 'd'? Can someone explain what the computer's thought process is? >I thought it'd be "Okay I'll print 'a'. Now I'll print 'b'. Ooooh \r, then I'll go to the very beginning of the line. Now I'll print 'd', and because I'm at the beginning of the line, that'll override the 'a' and 'b' I just wrote leaving just 'd'." The only thing I can think of is that /r only lets you override the first char, and not every subsequent thing Any input would be greatly appreciated... [link] [comments]  |
| Is implementing multi-processing going to save me time as a developer when debugging/testing? Posted: 08 Oct 2020 05:27 AM PDT We have some pretty massive datasets and it can take 5-10 minutes to run code outside a debugger, code inside a debugger a little longer. I was considering attempting to implement multi-processing. Splitting my dataset up into ~4 groups, and using multiprocessing to work on each at the same time. This only benefits me. In production, this code is run overnight/over weekends/ in the background. My question- Is this difficult to implement(Python)? Will I have new problems that you wouldn't run into without multiprocessing? Will this save me time in development? [link] [comments]  |

| Should I be using JavaScript or Python to make an Instagram scheduled upload program? Posted: 08 Oct 2020 07:10 PM PDT First of all I'm a complete newbie as it pertains to programming so excuse me if the question seems dumb. I currently manage 4 Instagram theme pages manually by myself. I'm looking to create a program that could be used to schedule uploads. I know this is against Instagrams terms of service, but I would just be trying to connect my program to my iPad and run it through that way. I have 2 questions. Is this even possible to do. I just want to schedule the post and then do all my engagement manually such as commenting and liking my followers comments. Could I do this with JavaScript or should I go about doing it with Python? I was planning on learning html, css, and JavaScript anyways. But if it's better to do in Python then I'd rather learn that first. I'm not trying to make money with it or anything. Just to help automate my process. I want to learn programming as a new skill and don't need it for work. [link] [comments]  |

| Posted: 08 Oct 2020 09:13 PM PDT I sometimes feel my life is a mess. I learnt programming in the first 2 years of my college and was average at it. However I was very motivated to do UI/UX and frontend. After trying to create UIs for a lot of apps and websites, I realised that I cannot create illustrations but only create screens using shapes, colors, typography, spacing etc. So I pivoted to writing HTML and CSS. At the penultimate year of my college companies start to hire and therefore I shifted back to programming. Since this was so asynchronous, I never truly learnt the fundamentals unlike my friends who dedicated their time to only programming. I however landed a job through programming. Now I am very much into frontend frameworks like angular, react and just creating sites out of them. That's my job too. Here's the problem. I have to pass a programming test in my organisation inorder to get myself promoted. I don't know how long will my life shift from programming to software development. I have no confidence and no motivation to learn programming now but I need to get promoted to learn from the best in my company. What is wrong with me? Also, I suffer from anxiety, depression if that helps. [link] [comments]  |
| Posted: 08 Oct 2020 09:04 PM PDT Hello everyone! I'm new at coding and would like some help on an assignment. I will post what I have so far in the comments section! I'm getting 5 errors but not sure why. Thank you! An accurate sales forecast is an important tool for companies to have. It helps managers gauge the demand for their products. It helps companies better manage inventory. It allows managers to financially plan for the company's growth. A sale team of XYZStartup wants to investigate the optimal price of their product to maximize their profit for the next several weeks of planning horizon, utilizing a simple formula provided below. 𝑆𝑎𝑙𝑒𝑠 = (𝑝𝑟𝑖𝑐𝑒) ∗ (𝑏𝑎𝑠𝑒 𝑑𝑒𝑚𝑎𝑛𝑑 − (1 + 𝑝𝑟𝑖𝑐𝑒 𝑠𝑒𝑛𝑠𝑖𝑡𝑖𝑣𝑖𝑡𝑦) ∗ 𝑝𝑟𝑖𝑐𝑒 + (𝑝𝑟𝑖𝑐𝑒 𝑠𝑒𝑛𝑠𝑖𝑡𝑖𝑣𝑖𝑡𝑦) ∗ 𝑐𝑜𝑚𝑝𝑒𝑡𝑖𝑡𝑜𝑟′𝑠 𝑝𝑟𝑖𝑐𝑒), where base demand is randomly drawn from 95 to 105 and price sensitivity is randomly drawn from 4 to 7. There is one competitor in the market. The competitor is vigilant enough to track your product price in real time using an AI tool so that they always copy your price strategy (e.g., the competitor's price is always the same as yours). You, as an IS professional, are required to develop a program that conducts the following process. (1) Reads a price from the user. The price must be in the range of $5 to $85. If the user provides a price out of the range, the program askes the user to provide a price again. (2) Calculate the sales (using the formula above) 30,000 times (3) Print out the average expected sales. [link] [comments]  |
| Wireshark: How can I use MAC addresses and TTLs to identify which interface a pcap was captured on? Posted: 08 Oct 2020 09:19 AM PDT Forgive me if this isn't appropriate for this subreddit, but I need some help regarding network security and I don't know where else to post this. I have a pcap and need to identify which interface it was captured on. In file properties, the interface is unknown. I have the MAC addresses and TTLs of each packet, but I don't know who captured the packets. Any help would be greatly appreciated. [link] [comments]  |

| Best practices/advice on going about programming projects / Getting things "done"? [N00B] Posted: 08 Oct 2020 03:40 AM PDT I'm not much of a programmer but run a business in which programming projects are regular - e.g get a landing page up, develop a web app etc. I'm looking to start outsourcing most of these projects to freelancers. I have used Upwork in past but inefficiently and it has cost more time than me doing alone. I operate alone and have never worked inside a business around programming so am not sure of the best practices when starting a project or getting basic things "done" through using one or multiple freelancers. For example, I have a landing page that requires a copywriter - I can get from Upwork - and a guy to code a quick static page for me to get domain and put on AWS. How do I go about this as efficiently as possible, any tutorials on outsourcing you can recommend, books, best practices or software to use to make group projects as quick and streamlined I apologize in advance for grammar errors or if what advice am asking for seems vague I am happy to elaborate as this was written quickly on phone [link] [comments]  |

| How to make _getche() only accept specific characters Posted: 08 Oct 2020 02:29 PM PDT I need input from the user to select and option (1 2 or 3) and want to make sure that they cant enter anything else than 1 2 or 3. It should not require the user to press the enter key, which is why I assumed you need to use getche(). I am a beginner by the way. The language is C++ [link] [comments]  |
| Posted: 08 Oct 2020 08:11 AM PDT It's mainly yes/no and integer user inputs. The decision tree for this process is massive and would be a gigantic flowchart. What if I create a table in excel that has every possible input field and make it so the output field generates every possible output scenario based on the combination of inputs? I just want to make it easier for the programmer to understand and implement the decision tree. [link] [comments]  |
| How would I build this? (Total beginner) Posted: 08 Oct 2020 01:51 PM PDT Hi all, Hoping this is the right place for a complete non-coder to ask about getting started. Basically, I run a small community scheme that matches random neighbours with each other every month to meet up for coffee. At the moment, the numbers are pretty small, so I just collect email addresses via a web form and match people manually, but as it grows it is becoming more labour intensive each month. So my question is, is it possible to create programme that will automate this process for me? If so, what do I need and where would I start? I thought that using a Macro in Excel would go some way to helping me, but I'm interested in learning how to code, so thought this would be a good project to try. Here's more info how the process works now, which I do on my MacBook: People sign up using a Google Form I would really love to be able to build something to automate this whole process. Hopefully this is simple enough to be achievable, but not so simple that it's meaningless to code something for… Many thanks! [link] [comments]  |
| Debugging serial communication Posted: 08 Oct 2020 01:10 PM PDT Hey All, I have loop back working on both computers, but when connected to each other, no joy. I used powershell to create and open a port and then did a $port.writeline("hello") and then $port.readexisting() with paperclip across pins 2 and 3 to get loopback. The connection is COM1 male connector on back of computer A. Then a female to female gender bender. Then a cable matters USB to rs232 serial Adapter with USB plugged into computer B, set as COM7. On both machines, at the gender bender, I can paperclip across 2 and 3 and loopback works. When I connect computer A to computer B, no data transmitted from A to B or from B to A. Both are set to 19200, none, 8, 1 Any ideas? I'm totally not desperate. [link] [comments]  |

| Possible error in Cracking the Coding interview textbook(6th edition)? Posted: 08 Oct 2020 08:34 AM PDT In the solutions section for the first chapter, in question 1.6 for string compression, it states that time complexity for concatenation of strings of length n each is O(n2) . But in question 1.9 for string rotation, it states that the time ccomplexity of the algorithm is O(n) despite containing concatenation.
But in question 1.9,

| What python libraries are useful for creating a price monitoring interface? Posted: 08 Oct 2020 06:02 AM PDT Hello, I'm currently working on a project in which I'm applying concepts from this book about trading and machine learning. I'm working in parallel on building some prototype trading system that has a simulator, and I'm not quite sure what would be an efficient clean way of live tracking prices for multiple stocks. What I mean by tracking prices is to have some app(possibly with an interface) that is constantly running which is connected to an api, and I'm expecting prices to reflect locally as soon as a price change happens in the same fashion as many trading applications have this already. Of course I'm not asking for code, I'm just asking for what tools / python libraries would be useful in creating such functionality. The non-clean way that I know is to scrape prices periodically using requests / scrapy or whatever every second/minute or so, but I don't think that's what happens in real life applications which is exactly what I'm asking for.

| Posted: 08 Oct 2020 11:55 AM PDT You are given an integer K and a string S that contains lowercase English alphabets of length N, where N is always a multiple of K. You are required to convert the given string to a special string. A special string is a string that follows a repeating pattern of K characters till the total length of the string is N. For example, if S = abedef and K = 2, then the special string can be ababab or bcbcbc or any other string that follows the mentioned criteria. In order to convert the string, you can perform an operation on the string. Considering lowercase English alphabet are set as circular, you can rotate the character of the string on either side in one operation. For example, for "a" you can rotate it to "b" or "z" You can perform this operation any number of times on any character of the string. Performing this operation once costs you 1 unit. The task is to convert the given string to a special string in the minimum cost. Input format: • The first line contains T denoting the number of test cases • Next T lines contain Two space separated integers K and S, where K is an integer and S is a string. Output format: For each test case, print the minimum cost in a new line. Constraints: 1<=T<=10 1<=K<=100 1<=S<=106 The string contains only lowercase English characters. Sample Input: 4 3 abcdefghi 3 abcabcabc 3 abcdefabc 1 azazaz Sample Output: 18 0 9 3 Explanation: abcdefghi is converted to a repeating pattern of defdefdef. Cost = 3+3+3+0+0+0+3+3+3=18. abcabcabc is already a repeating pattern. Cost = 0. abcdefabc is converted to abcabcabc. Cost= 0+0+0+3+3+3+0+0+0 = 9. azazaz is converted to aaaaaa. Cost = 0+1+0+1+0+1 = 3. [link] [comments]  |
