| Starting a job as a junior C developer Posted: 28 Jul 2020 06:17 AM PDT This is my first programming job and I would like to know on what things should I put emphasis on. I'll code hardware but I've never done anything like that. My knowledge of C theoretical mostly. I've done many puzzles though. Is there anything more specific about C developement, other than the general differences compared to other languages, which should I know or start learning before starting? Thanks for your time!

| Keeping an updated tally of changing records Posted: 28 Jul 2020 07:58 PM PDT I have a list of students and their subjects:
And I create a tally from the above list aggregating how many students are there in each subject:
The student list will keep on expanding and this aggregation will be done at regular intervals. The reason I'm keeping the Tally in a separate table in the first place is because the original table is supposed to be massive (this is just a simplification of my original problem) and so querying the original table for a current tally on-the-fly is unfeasible to do quickly enough. Anyways, so the aggregating is pretty straight forward as long as the students don't change their subject. But now I want to add a feature to allow students to change their subject. My previous approach was this: while updating the Tally, I keep a Also the reason why I keep a It works fine if all students are unique and no one changes their subject. But it breaks apart now because I can no longer account for rows that come before the counter and were updated. My second approach was using a But still I don't know how to actually update the Tally accurately. Say, Erik changes his subject from "math" to "english" in the above scenario. When I run the script to update the Tally, while it does finds the newly updated row but it simply says Is there a way this can be solved? To summarize my question again, I want to find a way to be able to update the Tally table accurately (a process that runs at regular interval) with the updated/modified rows in the Student table. I'm using NodeJS and PostgreSQL if it matters. [link] [comments]  | |||||||||||||||||||||||||||
| Best European Grad schools for MS in Computer Science with an emphasis on 3D graphics Posted: 28 Jul 2020 01:37 PM PDT Looking for grad schools out in Europe that offer a similar MS program to DigiPen's MS in Computer Science. Does anyone know of any? I love DigiPen's program, but I also want to study abroad. Does not have to be the exact same thing. Just sort of looking for something around image processing, 3D engine development, graphics processing, etc. Anything parallel to that realm. [link] [comments]  | |||||||||||||||||||||||||||
| Anyone try ditching their multi-monitor setup? Posted: 28 Jul 2020 06:13 PM PDT I am sure many of us are now working from. At work I had two large monitors and thought I could never program on a just a laptop. I've been programming on just my laptop at home for several months now. I originally planned on setting up a multi-monitor workstation, but found that after a couple of weeks getting used to it I am actually more productive on my 13in laptop. I find I can get in the zone a bit more easily. Anyone else find this to be true? [link] [comments]  | |||||||||||||||||||||||||||

| Posted: 28 Jul 2020 02:03 PM PDT As a hobby project, I'm trying to grow my programming skills by making a versioning system. Something similar to how Git works, or the edit history of a Wikipedia page: detecting changes to a document and saving them for a historical record of how that document changed over time. I've got most of it figured out, but I'm struggling with what exactly to save in the data model. I've got kind of a Catch-22 in my understanding: 1) If I only save the diff for each step (e.g. the two lines that changed out of a 10,000-line document), it's very efficient for storage. But then if I wanted to see the full document at any particular point in its history, the system would have to go aaaaaaaaaaall the way back through every change in the history and apply them recursively to "compile" the document to that point, which is wildly inefficient. 2) Conversely, I could save the full document in each step and just recalculate the diffs between any two version in the history as needed. This would improve the performance a lot, but also seems wildly inefficient to save an entire new copy of the file if you only changed one line. Can someone describe how this kind of thing is handled? I don't need specific code samples, just a conceptual understanding of how these systems store and retrieve their historical versions most efficiently.

| Need help reformatting/rearranging copy/pasted text string Posted: 28 Jul 2020 02:00 PM PDT I lack the vocabulary to Google what I'm trying to accomplish. In Windows, if I copy a string of text like this: LUV 2020-08-21 34.0 Calls I want it to be arranged in the following format, replacing the contents of the clipboard with this: BUY +100 LUV 100 21 AUG 20 34.0 CALL @ LMT Thats the basic idea. I dont know what tools I need to make it happen. Here's the actual nitty gritty. The input text will change but always be in this structure, with a single space between data: Input: "LUV 2020-08-21 34.0 Calls" is arranged as: [Ticker] [Date] [Strike] [Side] or [LUV] [2020-08-21] [34.0] [Calls] The output I want will always be the following static text, with the data from Input replacing the bracketed text after some reformatting Output: "BUY +100 LUV 100 21 AUG 20 34.0 CALL @ LMT" Brackets added to illustrate BUY +100 [Ticker] 100 [Date] [Strike] [Side] @ LMT or BUY +100 [LUV] 100 [21 AUG 20] [34.0] [CALL] @ LMT the "BUY +100, 100, @ LMT" will always be there in the base output string. Lastly here are the rough parameters for each input data, uh, section. [Ticker] can be used as is, whatever it is, move it to the new output string. [Date] needs to be reformatted from "2020-08-21" (year-month-day) to "21 AUG 20", thats day, 3 letter month, 2 digit year, space instead of dash. [Strike] can be used as is, moved to the new output string. [Side] input will either be "Calls" or "Puts", replace with "CALL" or "PUT" when moving to the output string. In my head I can sort of plan out how I'd have to script the rules, I started putting together an excel document that would parse a text file and kind of apply some rule based formatting but that was a whole other rabit hole. In reality I need a solution thats streamlined. I copy the text, hit a hotkey, the copied text gets processed and placed back in the clipboard ready for me to paste where ever. Can anybody point me in the right direction for this sort of action? I'm willing to learn and do the work I'm just not sure where to begin [link] [comments]  | |||||||||||||||||||||||||||
| What's the best web platform to blog in python and jupyter notebooks? Posted: 28 Jul 2020 04:45 PM PDT I'm trying to learn coding and advertising myself through blogging.

| Quickest Way to Make Python Script Communicating with G-Sheets Available to whole Team? Posted: 28 Jul 2020 04:26 PM PDT Hi all! Sorry for the vague description. In shortest terms, I wrote a little Python script which pulls a large chunk of Google Sheets data (~7000 rows with maybe 30-35 columns) goes through some operations based on predetermined variables and writes the edited range back into the sheet. However, as I have no programming background, I have no idea where to start with making this user-friendly and available to the whole team, as many people will have the need to write this script and ideally, more of the scripts of the same kind. Just the background of how little I know about how I would do this - I currently only know how to run this script myself from the terminal, so yeah :D Any suggestion is welcome. Ideally, I would love to make it as user-friendly as possible so that anyone from the team could just access it at any time and run it. I'm talking about real simple stuff - I just need two drop-downs and the run button, ideally accessible online. Background for anyone curious: I got in some kind of technical position without any prior experience or education in anything of the sort and I'm there for maybe year, year and a half. So far, I've been doing everything in Google Sheets - yes, I know it's far from ideal, but there's a huge number of reasons why Google Sheets are a must, not the least because boss very much prefer that we stay within Google ecosystem, so to speak. So, that explains why perhaps a very noob question and why Google Sheets. Also, and this might be a personal rant - Google officially offers 6 minutes runtime for the most basic G Suite solution. Unofficially, experience proves without any doubt (measured the time until timeout three times today) that in reality we get only 4 minutes of runtime. Why it takes more than 4 minutes for Google Apps Script to go through an array of ~7000 elements, I am really not sure. I know whole of the internet keeps on insisting that this shouldn't be happening, but again, experience proves otherwise. And yes, all the best practices have been followed, I literally have three getRange calls and one setValues at the very end. My Python script which is beyond basic does this in couple of seconds, so really not sure what's the issue. [link] [comments]  | |||||||||||||||||||||||||||
| Possible new RNG method, but how good is it? Posted: 28 Jul 2020 02:56 PM PDT I was playing around with number sequences and I think a certain kind will be non-repeating. I'm not certain how to double check nor how to test it's ability as an rng, but it does seem like it'd possibly be a fast one using only additions and modulos and a division to make the output into a float between 0-1. Basically, the sequences are where you take the tribonacci concept but modulo it. So you'd have A, B, and C (the three previous results), add them up and modulo the result. I did this with several number bases (the modulo number) and both 12 and 60 seemed non-repeating. Of course, with my limits I was only able to check the first 100 or so (at least till I can hit up a real computer). I figured that maybe a modulo of a few bytes or a touch less might have a similar case of long periods. Not sure how good a quality you could get out of it, but it seems simpler than a bunch of multiplication, divisions, and other more advanced operations. I think bitshifts are cheaper but I don't know much about those. What do you guys think? [link] [comments]  | |||||||||||||||||||||||||||

| How to shift my current IT career more toward programming Posted: 28 Jul 2020 12:20 PM PDT I have worked in IT for 10 years (since age 16) and my current job consists of general IT service for a rapidly expanding enterprise (we've hired consistently through the pandemic, even). It's a good position and a relatively good company, but I'm not positive I'm being paid as much as I should be based on my responsibilities. I was hired do relatively entry level/intermediate IT stuff, but due to circumstance, I am now (in addition to my other duties) in charge of programming, testing, and supporting the ACD/IVR for a multisite call center including remote employees and I'm consistently told I'm doing a fantastic job of it. I make about $48k. With that in mind, I have a couple of questions. 1: Am I being underpaid? I am doing semi-object based programming in the vendor's proprietary language which I learned of my own volition for a system which receives several thousand calls a day. And 2: is this experience enough to transition into a more programming focused job? I have basic experience with C++ and Java, and I'm working on an indie game in my spare time in GML. That said, I do not have an especially impressive or full portfolio of completed works (just a few jam-style games). [link] [comments]  | |||||||||||||||||||||||||||

| Strategy for updating a Tally table with changing rows in another table Posted: 28 Jul 2020 10:30 AM PDT I'm developing a reddit-like site where votes are stored per-user (instead of per-post). I have 2 tables (among others):
Tally table basically serves as a quick look-up table to get all aggregated upvotes and downvotes because I'm expecting the Votes table to get quite large and it wouldn't be feasible to retrieve and calculate each post's votes on-the-fly quickly enough. When I periodically update this Tally table I don't want to have to go though the entire Votes table each time as it'll get quite large and it won't scale well. It seemed all quite simple until I considered the user ability to change or withdraw their vote. My initial approach for a cron job logic was something like this:
But what if the user changes their vote? Second approach:
Ok, so I'll be able to get the record that was changed. Let's consider such a record:
But how do I now know what its previous value was, so as to update the I could go back to the counter approach, and instead of updating the This has two problems: First, I have to query the ID of the previous vote, which increases the overall operation time. Second, this complicates other things that I have to do with Votes that I won't bother you with, but it does. I'd really like it to not go this way, it seems unnecessarily complicated. Is there any other way that I'm not able to think? [link] [comments]  | |||||||||||||||||||||||||||

| Posted: 28 Jul 2020 08:45 AM PDT Hello! Im a third year computer engineering student who is gonna write his bachelor thesis starting January. Im looking for some insight in how to tackle this project, and have an idea myself that i want feedback on. Scenario Im working with a company that places out electric scooters in a city, which are rentable through a mobile application. There is planning involved every day to pick where to place these electric scooters where they will be used the most. I would like to automate the decision making of where to place the scooters, instead of them being placed in mostly fixed locations. Goal Through analyzing the available data, i want an algorithm to recognize patterns of use based on the conditions, and suggest the best places to park scooters for each day. The algorithm should also suggest the amount of bikes to place at each location. Data available About one years worth of data is available for the project. The data is the GPS location and timestamp for when a ride starts and ends. There are about 600 scooters available in the city at all times, and anything from 10 - 70 scooters are in use at any time. Each ride last for on average 15 minutes. With the GPS location and timestamps as data, i also want to retrieve weather data for each timestamp, as usage also is dependant on the weather. Examples of usage based on conditions Good vs bad weather will determine if the scooters are used for reaching indoors facilities such as indoors waterparks, city exploration, beach going etc. Time of day and day of week determines if the scooters are used for transportation to work/school, leisure activites, tours of landmarks, religious gatherings and more. Initial idea for solving My initial idea is to compact all the data into heatmaps that describe usage based based on each condition. For example there might be multiple heatmaps for usage based on temperature where there is one heatmap for each range of temperature (For example one heatmap for 15-17.5 °C , one for 17.5-20 °C ...). In the same way, there would be heatmaps based on ranges of time and each day of the week... To retrieve the suggested spots to place scooters at any given day, heatmaps are chosen that are the closest to the conditions for that day. With each heatmap contributing and being weighted differently, they are combined into a final heatmap that describes the most optimal locations to place for that day. Challenges A problem could be if the data is more random than anticipated, with patterns being hard to recognize. There is also the issue of creating heatmaps for each separate condition. For example, 1 pm on one day and 1 pm for another day will probably have different weather conditions, and so separating usage based on the time each day from weather conditions may prove difficult. I would really appreciate any suggestions on the challenges i might face, or if there are any other ideas to solve such a task. Thank you! [link] [comments]  | |||||||||||||||||||||||||||
| Where to start for building web applications? Posted: 28 Jul 2020 03:20 AM PDT Hello! I have some very basic understanding of programming (learned some C++ in school, know the syntax of HTML and CSS, some very basic JS), but nothing more than that. I have a couple of ideas about web applications, one of which is basically a location-based hub for events around you, and my idea is to first make it accessible for browsers - both desktop and mobile, then make a mobile app. Obviously this is not a one man job, but I really want to know where to start in order to build like a simple prototype and I also want to know how to make applications that display the same information both to the web and to the mobile app. Any help will be much appreciated!
