| Posted: 14 Oct 2018 09:45 PM PDT I cut my teeth on coding as a high schooler banging out class/HW exercises in turbo PASCAL. After taking your typical 3 semester lower division intro CS classes in college, I never really touched any code at all unless you count some scripting-type stuff in MATLAB. The main threads of what I remember in broad strokes from my c/c++ based programming I,II, III consisted of string operations, data structures, and object oriented principles and practices. It's all a blur. Everything I'd used to work on, including the IDE itself (such as they were in the pre-graphic days), fitted on a floppy. (<1.44 MB for those not in my target audience.) I lost a lot of sleep back in the day, but I confess I regard Borland fondly and with nostalgia. Fast forward to today, I am completely overwhelmed by what I see. Python seems to be the teaching language of choice for many structured courses. not too scary. However, the IDEs in use, such as MS Visual Studio, appear absolutely monstrous compared to text based and command line environment I used to work on. People now talk about "code refactoring"(?) and it isn't rare for collaborative project assignments involving the use of CVS code management tools, which I was aware of as a young student but was never required to learn. Similarly, competency with debugging tools/techniques appear to be a must. I feel like I'm functionally starting from scratch, as the total mentality and attitude in writing code and software development has evolved beyond what I experienced as a young student. (edit: Or maybe I just received a REALLY bad education without the real world experience to realize it.) The rise of mobile devices appear to have made languages like Objective-C & Swift popular for aspiring developers in the Apple camp. In that vein, I've been given lots of "advice" from those with specific goal-oriented motivations in acquiring programming skills/experience. I don't necessarily want to help build the next release of "Call of Duty" or engage in commercial work. I'd like to think I'm seeking to be a well-rounded generalist with a good set of core skills. But it would be nice to become proficient enough with parallel programming techniques/methods to use today's modern hardware to crunch pattern matching problems. Until I realized how rusty I'd become on the basics, I foolishly believed I could pick up OpenCL, CUDA, and OpenMPI without too much trouble. Such as things are, I need to spend some time "learning to walk" again, so to speak. But it sure feels like I'm an Earth-born Terran navigating an alien planet with toxic atmosphere and a different gravity, lol. I have no idea how much effort is really involved ahead of me at the moment. But if there is anything you can offer that can help me get a lay of the land to better get from here to there, it would be much appreciated. tl;dr: Trying to brush up after taking classes but never using programming skills since the 2000s. Not a complete N00b, but feel like one given the changes in the last 20-ish years. seeking advice. [link] [comments]  |

| Is CMake + Visual Studio + CLang possible? Posted: 14 Oct 2018 10:54 PM PDT Hello! I'm currently using CMake to build my project in Visual Studio. This gives me the best of both worlds [when Visual Studio doesn't crash/bug], but I'd like to really get the best of everything by adding CLang into the mix. Using CLang as my compiler would allow me to use clang-tidy to do some linting and static analysis on my project. Is using CLang with Visual Studio and CMake possible? How can I do that? Here's my CMakeLists https://github.com/Pierre-vh/Moonshot/blob/master/CMakeLists.txt Thank you! [link] [comments]  |

| Can't figure out how to find smallest Index our of three IndexOf [Java] Posted: 14 Oct 2018 09:21 PM PDT hopefully that code is enough, I am working on an assignment but cant seem to work this bit out, basically i want smallestIndex to take the value of the true smallestIndex but as they return as -1 I believe this is causing some issues. Suggestions please! Edit: before anyone says yes i know it's poorly laid out and done this is a introductory class please go easy on me :) [link] [comments]  |
| Why Is there a base64 size difference between a generated UIImage, and a referenced local image? Posted: 14 Oct 2018 08:58 PM PDT I have two base64 strings, that are generated from the same image. One is generated after the initial capture of an image (relevant conversion code below) and then it is saved to the user's disk, and the other is generated through an Ionic plugin called "Image-Picker". Now when I went to compare the two images, I noticed that the "picked" one was almost 2.5 times smaller than the one that I originally captured. The only thing I can think of is that the originally captured image is converted into a UIImage, and then converted into a base64 generated image, but I'm not sure why that would add so much extra overhead to the base64 size.

| Any tips or programs that can help organize a growing pdf library? Posted: 14 Oct 2018 07:05 PM PDT I'm not sure if this is the right place for this or not, but I'll ask anyways. I find that as I develop my programming skills, I've accumulated more and more pdf files of documentation and e-books that are growing more and more disorganized. Right now, I just have one big folder with a few subfolders. But, I was wondering if anyone knew of any programs that are helpful for maintaining a pdf library? [link] [comments]  |

| Posted: 14 Oct 2018 05:43 AM PDT I've seen many websites, blogs and even here on Reddit where people new to programming languages are told to learn Python. About 15 yrs ago when I was in university, we were taught Java as a part of curriculum. I believe this is bad. These languages do not have any semblance of the computer that it's actually running on. Eventually, I've heard veteran programmers telling things like, "I don't care, I'll create as many threads and let Java do what's needed" or "Why do I have to know about dependencies, Maven will handle it" and so on. Maybe it's just me or has others come across these kinds of "veterans" because they lack understanding of computers? Why are so many advised to learn basics using unrealistic languages that focus purely on algorithms and not the hardware it runs on? Edit: Lots of people have commented about things that are beyond the scope of this discussion. About 10 yrs ago I came across a piece of code that kept track of power states on various lines. When there were voltage fluctuations this would send out a block showing the reason for such fluctuation or even power failure. It worked for 99% times, but when it came to the last power source it failed. Developers blamed hardware team, hardware team blamed the poor manufacturing quality and so on. This feature wasn't important, at least no spec or standards mandated this feature. But this feature could've helped those field operators a lot. They didn't have to walk/drive in desert sun for several kilometers to pull out the sensors from pits. They could've sat in their cozy air-conditioned rooms monitoring status. When I dug inside, I found it was tracking power states as bit fields stuffed inside a This humane responsibility is something that's missing in modern developers who only strictly focus on absolute business needs. Note, again, this has nothing to do with optimisation, but efficient and correct programming. I felt this is likely because of the way people are learning programming and I asked this question. But somehow the discussion seems to have diverged far off. [link] [comments]  |
| How to beat junior dev salary by going self employed? Posted: 14 Oct 2018 02:27 PM PDT hello. I wonder how to, or better said, how likely it is that junior software dev can beat his salary by going self employed? Of course one way is to develop a product and sell it, but hey, that's way harder and less likely to achieve in comparison to..... finding clients and work for them, or in other words, contracting your ass out. So lets take a look at working for clients. The math. Average salary for junior dev in US is 70kUSD, after tax that's about 54kUSD. The point is that junior software engineer is one greedy mofo and wants to earn one fold more as in 9-5 employment. Therefore target net income becomes 108kUSD. As self employment taxes and health insurance eats half of income, this means that we need to earn 216kUSD. Yayks. Further, in a year one would probably have 1 month for vacation and sickness, and 3 months of gaps when searching for clients. Therefore there is 8 months of productive time. At 160 work hours per month, that's 8x160=1280 of work hours per year. If we divide 216kUSD by 1280 hours, we get hourly rate which is 168,75 bucks/hour.... Seriously? Who is going to pay you that amount of money? I think that's a hourly rate that sw dev agencies charge, and those are some serious mofos with decade of experience. In fact, I've googled what's the hourly rate for junior contractors - it ranges between 40 to 60 bucks. Way less than we need. Further, if we take 50bucks per hour and assume 1280hours of work per year (same as before), that's 64kUSD per year or about 32kUSD after tax and health insurance. Is moral of the story don't contract your ass out because it's totally not worth it? [link] [comments]  |
| Help converting to binary in VB multiple times Posted: 14 Oct 2018 01:51 PM PDT Hey everyone, this is my first post on this sub.

| Do students own their homework / project code? Can I push my school work to public repos? Posted: 14 Oct 2018 01:49 PM PDT Assuming the code is not largely based on a skeleton code given by school, I see no reason to deny students ownership of their work, which means they should be able to upload and showcase their work on github public repos. Some of the school projects at my school are rather complicated and are worth showcasing, some of them are even drivers for specific sensors / boards and can be developed into an open source project later. However my professor said multiple times not to push code to public git repos, even after semester ends. Is there any legal basis to their statement? What kind of trouble will I get into if I use public repos anyways? [link] [comments]  |

| How differently are pointers and array represented in memory in C? Posted: 14 Oct 2018 12:21 PM PDT I'd like to know how differently pointer and arrays are treated in C. I know this is not part of the C standard and is implementation defined, so I'll give an example in my Linux computer. If I create and assign an array as While It seems that a pointer involves less operations, which makes sense, but I'd like to know in plain language what's happening here. [link] [comments]  |
| Question about loose coupling with data objects Posted: 14 Oct 2018 11:54 AM PDT I'm working on a project where I find myself reaching through (active record) data objects frequently to maintain a normalized data model: and the like. I realize this tightly couples my various data models (Organization, Place, and ImageObject in this example). Is this okay in the context of a normalized data model? Is there a good alternative? Is this just inherent in AR ORMs, and something I'd avoid using a data mapper ORM? Denormalizing the model is a separate issue and I understand various trade-offs with doing so. My question is more about coupling when denormalizing isn't appropriate. [link] [comments]  |

| Is it safe to unpickle this in python? (spoilers for python challenge) Posted: 14 Oct 2018 05:54 AM PDT I'm just starting to learn a little bit of python, and I'm doing the puzzles on pythonchallenge.com. I've got to one about pickling/unpickling, and I think I'm meant to unpickle the characters I found here: pythonchallenge.com/pc/def/banner.p . However, when I was reading about pickling/unpickling, it said to never unpickle from a source you don't trust. I don't know/trust the guy who made the puzzles, but I think maybe it is okay to unpickle these characters because there are so few of them, he couldn't harm my computer by me unpickling it? ps. I only want to know if it is safe to try to unpickle those characters, not if I am on the right track with the puzzle :) Edit: also here is the page for this puzzle: http://www.pythonchallenge.com/pc/def/peak.html inspect element for the clues [link] [comments]  |

| mDNS for resolving a .local hostname (Windows Embedded Compact 2013) Posted: 14 Oct 2018 03:49 AM PDT Hello All, I'm tyring to use mDNS on a Windows Embedded Compact 2013 device to resolve a .local hostname from a DNS server from the same subnetwork. I used the code below on a test program (4.7.1 .NetFramework Application) and it succesfully received an answer with the SRV record. But my code does not work on my Windows Embedded Compact device, as the server does not receive my query. So my question is as following: is this code not valid for a Windows Embedded Compact 2013 device or am i missing something? Other solutions for my problem are very welcome and i'm thanking you in advance. [link] [comments]  |
