• Successful Common Code Libraries

  - by Adam Jenkin

  Are there any processes, guidelines or best practices that can be followed for the successful implementation of a common code libraries. Currently we are discussing the implementation of common code libraries within our dev team. In our instance, our common code libraries would compliment mainstream .net software packages we develop against. In particular, im interested in details and opinions on: Organic vs design first approach Version management Success stories (when the do work) Horror stories (when they dont work) Many Thanks

• Techniques to read code written by others?

  - by Simon

  Are there any techniques that you find useful or follow when it comes to reading and understanding code written by others when Direct Knowledge Transfer/meeting the person who wrote the code is not an option. One of the techniques that I follow when dealing with legacy code is by adding additional debugging statements and based on the values I figure out the flow/logic. This can be tedious at times. Hence the reason behind this question, Are there any other techniques being widely practiced or that you personally follow when it comes to dealing with code written by other people/colleagues/open-source team?

• How to write good code with new stuff?

  - by Reza M.

  I always try to write easily readable code that is well structured. I face a particular problem when I am messing around with something new. I keep changing the code, structure and so many other things. In the end, I look at the code and am annoyed at how complicated it became when I was trying to do something so simple. Once I've completed something, I refactor it heavily so that it's cleaner. This occurs after completion most of the time and it is annoying because the bigger the code the more annoying it is the rewrite it. I am curious to know how people deal with such agony, especially on big projects shared between many people ?

• Code Measuring and Metrics Tools?

  - by David

  I'm in the process of setting up a build server for personal projects. This server will handle all the normal CI stuff, including running large suites of tests (unit, integration, automated UI). While I'm working out the kinks for including code coverage output with MSTest, it occurs to me that there may be lots of tools out there which give me additional metrics other than just code coverage. FxCop comes to mind as an example. Though I'm sure there are others. Anything that can generate useful reportable data and metrics would be good. Whether it's class dependency charts (looking for Law of Demeter violations, for example), analyses of the uses of classes/functions (looking for a function that isn't used in the system other than just the tests, for example), and so on. I'm not sure the right way to formulate the question, since polling questions or "What's your favorite code analysis tool" aren't very good. But I'm essentially just looking for recommendations on what metrics to gather and the tools that can gather them. The eventual vision for something like this is to have the CI server run a bunch of automated tests and analysis tools and track performance metrics over time. Imagine a dashboard full of graphs plotting these metrics over time. The lines should all relatively be at an equilibrium, and if one starts to stray toward the negative then it's an early indication of problems with the code. In the age old struggle to quantify code quality with management, this sounds like a potentially helpful means of doing just that.

• What should my "code sample" look like?

  - by thesunneversets

  I've just had quite a good phone interview (for a CakePHP-related position, not that it's especially important to the question). The interviewer seemed to be impressed with my resume and personality. At the end, though, he asked me to email him a code sample from my existing work project, "to check you're not secretly a terrible programmer, ha ha!" I'm not too worried that my code can't stand on its own two feet, but I'm very much an intermediate programmer rather than an expert. What obvious pitfalls should I make sure my code sample doesn't fall into, in case they rule me out on the spot? Secondly, and this is probably the harder part of the question to answer, what features in a code sample would be so impressive that they would instantly make you much more favourably inclined towards the programmer? All ideas or suggestions welcomed!

• Questions about Code Reviews

  - by bamboocha

  My team plans to do Code Review and asked me to make a concept what and how we are going to make our Code Reviews. We are a little group of 6 team members. We use an SVN repository and write programs in different languages (mostly: VB.NET, Java, C#), but the reviews should be also possible for others, yet not defined. Basically I am asking you, how are you doing it, to be more precise I made a list of some questions I got: 1. Peer Meetings vs Ticket System? Would you tend to do meetings with all members, rather than something like a ticket system, where the developer can add a new code change and some or all need to check and approve it? 1. What tool? I made some researches on my own and it showed that Rietveld seems to be the program to use for non-git solutions. Do you agree/disagree and why? 2. A good workflow to follow? 3. Are there good ways to minimize the effort for those meetings even more? 4. What are good questions, every code reviewer should follow? I already made a list with some questions, what would you append/remove? are there any magic numbers in the code? do all variable and method names make sense and are easily understandable? are all querys using prepared statement? are all objects disposed/closed when they are not needed anymore? 5. What are your general experiences with it? What's important? Things to consider/prevent/watch out?

• What is the difference between Static code analysis and code review?

  - by Xander

  I just wanted to know what is the difference between static code analysis and code review. How these two are done? What are the tools available today for code review/ static analysis of PHP. I also like to know about good tools for any language code review. Thanks in Advance. Xander Cage Note: I am asking this because I was not able to understand the difference. Please, I expect some answers than "I am Mr.Geek and you asked an irrelevant bla bla..... this is closed". I know this sounds mean. But I am sorry.

• How to organize continuous code reviews?

  - by yegor256

  We develop in branches. Before a branch gets merged into the main stream (master branch) we review the changes made, by creating a new "code review" in Crucible. Reviewers add their comments to the code review and the ticket/branch gets bounced back to the author, if it needs to be improved. After the improvements are made we get this branch/ticket again back to the code review. We again create a new code review in Crucible, loosing all previously made comments. We simply start from scratch. It's a big waste of time. Do you know any tools that support a continuous mode for reviews, where we don't need to start from scratch every time, but can pick up the comments already made (re-start the review, so to speak).

• HedgeWar code confusion

  - by BluFire

  I looked at an open source project(HedgeWars) that was built using many programming languages such as C++ and Java. While I was looking through the code, I couldn't help noticing that all the math and physics were gone from the Java code. HedgeWars I imported the project file called "SDL-android-project" which was a sub folder to "android build" and project files. My question is where is all the math and physics inside the code? Do I have to look at the C++ code in order to see it? I think Hedgewars was originally programmed in C++ but the files are confusing be because of its size and the fact that it has several programming languages inside.

• Are flag variables an absolute evil?

  - by dukeofgaming

  I remember doing a couple of projects where I totally neglected using flags and ended up with better architecture/code; however, it is a common practice in other projects I work at, and when code grows and flags are added, IMHO code-spaghetti also grows. Would you say there are any cases where using flags is a good practice or even necessary?, or would you agree that using flags in code are... red flags and should be avoided/refactored; me, I just get by with doing functions/methods that check for states in real time instead. Edit: Not talking about compiler flags

• Logistics of code reuse (OOP)

  - by Ominus

  One of the driving points behind OOP is code reuse. I am curious about the actual logistics of this and how others both in team or solo handle it. For example lets say you have 5 projects you have worked on and between them you have a ton of classes that you think would be useful in other projects. How do you store them? Are they just in the normal project repository or do you break out the relevant classes and have them (as now copies) in another unique source repository that only houses code pieces that are intended to be reused? How do you go about finding or even knowing that there is a good piece of code out there that you should reuse? It's easier if your solo because you remember that you have coded something similar but even then it becomes kind of a stretch. If there is some way that you are storing these pieces of code do you then also have them indexed and searchable by tag or something. I fear that it just boils down to some tribal knowledge that you just know that for situation A i need solution B and we have a good piece of code that already can help here. A bit verbose but I hope you get what I am aiming at. If you think of a better way to make the question clearer please have at it :) TIA!

• How to keep unreachable code?

  - by Gabriel

  I'd like to write a function that would have some optional code to execute or not depending on user settings. The function is cpu-intensive and having ifs in it would be slow since the branch predictor is not that good. My idea is making a copy in memory of the function and replace NOPs with jumps when I don't want to execute some code. My working example goes like this: int Test() { int x = 2; for (int i=0 ; i<10 ; i++) { x *= 2; __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) x *= 2; // Op to skip or not x *= 2; } return x; } In my test's main, I copy this function into a newly allocated executable memory and replace the NOPs by a JMP 2 so that the following x *= 2 is not executed. The problem is that I would have to change the JMP operand every time I change the code to be skipped. An alternative that would fix this problem would be: __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) goto dont_do_it; x *= 2; // Op to skip or not dont_do_it: x *= 2; This way, as a goto uses 2 bytes of binary, I would be able to replace the NOPs by a fixed JMP of alway 2 in order to skip the goto. Unfortunately, in full optimization mode, the goto and the x*=2 are removed because they are unreachable at compilation time. Hence the need to keep that dead code.

• Can I have both Windows dynamic disk partition and some other non-Windows partition on the same disk?

  - by haimg

  When a basic Windows disk is converted to dynamic, Windows creates a partition that span the whole disk with the type of "Windows LVM" and manages its dynamic partitions within this space. So even if there is still free space on this disk, it is not visible to any other OS besides Windows. This happens with MBR and GPT disks both. I would like to share a Windows dynamic disk with some other OS. I have to have dynamic disks because I use Windows SoftRaid (mirrors). So, my questions are: Is there any way to "force" Windows to take up less then the whole disk when it converts a basic disk to dynamic? Will Windows tolerate having some other non-Windows partition on its dynamic disk?

• How to create an Intellij and Eclipse compatible code style and code formatting configuration (for j

  - by user141634

  Few weeks ago I tried Intellij and I found it really awesome. Now, at my project there's two programmers (including me) using Intellij and few other programmers gonna still be using Eclipse. Since this project is already very large and it gonna be growing a lot, we need to use compatible Code Style and Code Formatting between Intellij and Eclipse. We do not want to have problems when one user edit one file and reformat it before save. With Eclipse "alone" we used to have some exported configuration, and before anybody starts to work, the first step is just to import this configuration. We already tried to use External Code Formatter, but it didn't work on Intellij 9. So, I have a bunch of questions here: 1 - Is there any way to import eclipse formatting configuration on Intellij 9? 2 - Anybody could share their experience managing this kind of situation? Do you guys have any other suggestion to manage this situation?

• Example of code generator you made from scratch?

  - by rosscj2533

  What are some examples of code generators you have used? I think it's a cool idea, but I have trouble thinking of things they can do besides make a class based on an object's attributes/database schema (as described in The Pragmatic Programmer). What language did you write them in and what language did they output? Edit: Thanks for the responses so far. What I am really looking for is examples of code generators made from scratch for some certain purpose. I mentioned it in the title, but didn't make it very clear in my question. How did you go about making a code generator on your own and what specificly did it achieve?

• Is it customary for software companies to forbid code authors from taking credit for their work? do code authors have a say?

  - by J Smith

  The company I work for has decided that the source code for a set of tools they make available to customers is also going to be made available to those customers. Since I am the author of that source code, and since many source code files have my name written in them as part of class declaration documentation comments, I've been asked to remove author information from the source code files, even though the license headers at the beginning of each source file make it clear that the company is the owner of the code. Since I'm relatively new to this industry I was wondering whether it's considered typical for companies that decide to make their source code available to third parties to not allow the code authors to take some amount of credit for their work, even when it's clear that the code author is not the owner of the code. Am I right in assuming that I don't have a say on the matter?

• Dynamic DNS with Comcast

  - by colithium

  I've just recently moved across town. Previously, I had Dynamic DNS set up so I could remotely connect to my desktop (primarily to use TightVNC). My ISP was Comcast and I'm in the Denver, Colorado area. Currently, I'm still with Comcast and still in Denver. My router connects to the internet just fine and my Dynamic DNS record over at DynDNS did get updated with my router's current external IP address. So my router, DynDNS, and public DNS records all agree what my IP address is. However, I can't actually connect to anything from the outside world. My trace route to Google looks something like: Tracing route to google.com [74.125.19.147] 1 3 ms 1 ms 1 ms 192.168.1.1 (this is the internal IP address of my router) 2 * * * Request timed out. 3 9 ms 8 ms 10 ms te-8-2-ur02.wheatridge.co.denver.comcast.net [68.85.221.177] 4 12 ms 12 ms 19 ms te-0-8-0-2-ar02.aurora.co.denver.comcast.net [68.86.103.97] 5 16 ms 13 ms 11 ms pos-0-3-0-0-cr01.denver.co.ibone.comcast.net [68.86.91.1] 6 28 ms 28 ms 27 ms pos-0-9-0-0-cr01.dallas.tx.ibone.comcast.net [68.86.85.174] 7 29 ms 27 ms 28 ms pos-0-1-0-0-pe01.1950stemmons.tx.ibone.comcast.net [68.86.86.94] 8 66 ms 108 ms * 75.149.231.70 9 65 ms 68 ms 93 ms 72.14.233.77 10 67 ms 66 ms 66 ms 72.14.233.111 11 67 ms 67 ms 69 ms 216.239.43.144 12 68 ms 71 ms 73 ms 209.85.249.30 13 66 ms 66 ms 68 ms nuq04s01-in-f147.1e100.net [74.125.19.147] This is what the trace route looks like from an outside source to my DynDNS domain name: traceroute to 98.245.67.65 (98.245.67.65) 1 illuminati-130 138.67.130.61 2 138.67.63.253 138.67.63.253 3 vermiculite 138.67.253.20 4 csm-ct-gw 138.67.253.244 5 138.67.253.2 138.67.253.2 6 ge-7-24-ar01.denver.co.denver.comcast.net 68.86.128.17 7 te-0-4-0-0-ar02.denver.co.denver.comcast.net 68.86.179.21 8 te-9-3-ur01.wheatridge.co.denver.comcast.net 68.86.103.18 9 * * * {Times Out} Now my guess is, whatever is sitting just beyond my router (what the modem connects to) is gumming things up. Even though the routes aren't EXACTLY the same, that appears to be the spot that the trace route either stops or doesn't get a response. My question is, for Comcast networks (particularly in Denver), what would be the device that typically sits there? Is there anything I can do about it? That device seems to not respond to PING but does forward it along when I'm going outwards. But it looks like it eats it when the request is coming in. It's hard to prove that from these logs but I'm assuming that's the case because my router used to accept connections from the outside and I haven't changed anything on it.

• Using dynamic dns updater as Windows service

  - by Sami-L

  Currently I am using a dynamic dns updater software on Windows, but to keep it updating I have not to close it, also the software is not able to run at backgoud, I searched on google but the answer became complicated since there are many details to pay attention to, free, not free, installed on machine, configured on router, trusted, not trusted ... So please help me find a trusted free dns updater for Windows which can run as service, and maybe which can send email when update fails.

• Recover data from a Windows Dynamic Volume Spanned Disk

  - by iCe

  I have a dynamic volume created with two spanned partitions over two disk. Recently, one disk has started failing, and I want to copy the data inside that disk to another disk, before replacing it. However I don't know how to select only what is inside the failing disk, because the partitions spans across both disks. Maybe imaging the entire disk should do the work? Or I have to copy all the data from both disks? Thanks in advance!
