• Absolute Top Programming Tips [closed]

  - by Eric

  I'm very intersted in the stuff that REALLY makes a critical difference to career in programming, other than intrinsic stuff like how smart your are, where you were born, etc... Some ideas: 1) Best approach to managing small, medium, and large teams. 2) Most important books to read. 3) Most important skills to know. 4) Correct balance of learning theory vs. just writing code. 5) A good approach to estimating time and cost of a project. 6) Etc... Please limit your answers. If you see somebody has already written your idea, please just vote for their response. I'd like to see what the community thinks are the true indicators of a successful career in our field.

• Where can I find accessible bug/issue databases with complete revision history

  - by namenlos

  I'm performing some research and analysis on bug/issue tracking databases and more specifically on how programmers and teams of programmers actually interact with them. What I'm looking for involves understanding how those databases change over time. So what I don't need for example: is a database of all the bugs of some open source project as the bugs exist today. What I do need is a complete set of revision history for every issue/bug in the database. This would enable me to pick a specific datetime and say here were the list of all the issues/bugs that existed at that moment in time. Anyway know of some publicly accessible issue/bug databases that expose this revision data? Ideally, the revision would look something like this (shown for a single bug, with two revisions) ISSUEID PRI SEV ASSIGNEDTO MODIFIEDON VALIDUNTIL 1 2 2 mel apr-1-2010:5pm apr-1-2010:6pm 1 2 3 steve apr-1-2010:6pm NULL

• Using EPEL repos with Oracle Linux

  - by wcoekaer

  There's a Fedora project called EPEL which hosts a set of additional packages that can be installed on top of various distributions such as Red Hat Enterprise Linux, CentOS, Scientific Linux and of course also Oracle Linux. These packages are not distributed by the distribution vendor and as such also not supported by the vendors (including Oracle) however for users that want to pick up some extras that are useful, it's very easy to do this. All you need to do is download the EPEL RPM from the website, install it on Oracle Linux 5 or Oracle Linux 6 and run yum install or yum search to get the packages. example : # wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm # rpm -ivh epel-release-6-5.noarch.rpm # yum repolist Loaded plugins: refresh-packagekit, rhnplugin repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 7,124 The folks that build these repositories are doing a great job at adding very useful packages. They are free, but also unsupported of course.

• How much should I charge for a web app

  - by Kostas

  I am a freelance web developer and I am working on a PHP/MySQL/Javascript based project. It's a web app that uses a custom CMS with user types, followers system, search forms, blogs, social integration. It will take about 3 months to finish, according to a roadmap I make (based on current development stage) and about a month after that for bug fixing and testing. So I have to tell them a price. What price range you think it's appropriate?? (It's a good regular client, so I want something reasonable) Can you give me some ideas?? Thanks.

• Having a generic data type for a database table column, is it "good" practice?

  - by Yanick Rochon

  I'm working on a PHP project where some object (class member) may contain different data type. For example : class Property { private $_id; // (PK) private $_ref_id; // the object reference id (FK) private $_name; // the name of the property private $_type; // 'string', 'int', 'float(n,m)', 'datetime', etc. private $_data; // ... // ..snip.. public getters/setters } Now, I need to perform some persistence on these objects. Some properties may be a text data type, but nothing bigger than what a varchar may hold. Also, later on, I need to be able to perform searches and sorting. Is it a good practice to use a single database table for this (ie. is there a non negligible performance impact)? If it's "acceptable", then what could be the data type for the data column?

• How does one handle sensitive data when using Github and Heroku?

  - by Jonas

  I am not yet accustomed with the way Git works (And wonder if someone besides Linus is ;)). If you use Heroku to host you application, you need to have your code checked in a Git repo. If you work on an open-source project, you are more likely going to share this repo on Github or other Git hosts. Some things should not be checked in the public repo; database passwords, API keys, certificates, etc... But these things still need to be part of the Git repo since you use it to push your code to Heroku. How to work with this use case? Note: I know that Heroku or PHPFog can use server variables to circumvent this problem. My question is more about how to "hide" parts of the code.

• How do you remember where in your code you want to continue next time?

  - by bitbonk

  When you interrupt the work on some code (be it because you have to work on something else or go on vacation or simply because it is the end of the day), once you close that Visual Studio project, what is your preferred way to remember what you want to do next when you start working on that code again. Do you set a Visual Studio bookmark or do write down something like // TODO: continue here next time? Maybe you have a special tag like // NEXT:? Do you put a sticky note on your monitor? Do you use a cool tool or Visual Studio plugin I should know? Do you have any personal trick that helps you find the place in your code where you left off the last time you worked on your code?

• Resources for Virtual Machine programming

  - by good_computer

  I am a beginner (a little more than that) programmer of C. I am really interested in the field of Virtual Machines. When I read about the Python VM, the PyPy project, the advancements in JVM technology, Google V8, the Erlang VM, I really get excited about these amazing pieces of technology, and really want to get my hands dirty building them or contributing to one of these projects. I need to know.. what are the things (language, concepts, algorithms, math, etc?) I need to know/learn to be able to build a virtual machine any books or other resources that will be helpful career prospects for a virtual machine engineer (but this is least important for me for now) (one more side question: somewhere I'd read something like JVM is on the cutting edge of virtual machine technology -- that it is the most advanced VM so far -- is that true?) Please give me a LONG answer detailing all that you know.

• ISO, Six Sigma, SEI-CMM, etc., in Fortune 500 companies

  - by CMR

  Do large corporations and product companies follow any standard quality models/processes at all? For example, I have seen that many large organizations have proprietary processes in IT and software development. Back in the days (even before Motorola's Iridium project,) I remember many IT companies scampering for SEI-CMM certification. Do any of the Fortune 500 company try to adopt these quality processes? In my limited experience I have not seen them undergoing audits for adherence to processes. Most of the audits are either financial, or issues pertaining to legalities. Am I just being ignorant, or is this true? If true, how stringently do the companies adhere to the processes?

• Track those visitors who come through a particular link

  - by busybee235

  I want to track visitors who come to my site through a particular link. For example, those visitors coming from http://www.domain.com/abc123, I can get their pageviews, time on site, bounce rate, referrer pages per visit etc. After that I can store that info into by database on daily basis. Can anyone suggest any service or api or any software for the same? I have used Google Analytics utm tags that work straight well for my requirement but I don't know how many links I can track with it. I have around 80-100 links to track a day and the number of links will be increasing. I couldn't find any documentation regarding limit of campaigns in GA. If there's no such limit, I can start this project. Thanks

• Create association between informations

  - by Andrea Girardi

  I deployed a project some days ago that allow to extract some medical articles using the results of a questionnaire completed by a user. For instance, if I reply on questionnaire I'm affected by Diabetes type 2 and I'm a smoker, my algorithm extracts all articles related to diabetes bubbling up all articles contains information about Diabetes type 2 and smoking. Basically we created a list of topic and, for every topic we define a kind of "guideline" that allows to extract and order informations for a user. I'm quite sure there are some better way to put on relationship two content but I was not able to find them on network. Could you suggest my a model, algorithm or paper to better understand this kind of problem and that helps me to find a faster, and more accurate way to extract information for an user?

• Recommended solutions for integrating iOS with .NET, at the service tier

  - by George

  I'm developing an application, in iOS, that is required to connect to my Windows Server to poll for new data, update, etc. As a seasoned C# developer, my first instinct is to start a new project in Visual Studio and select Web Service, letting my bias (and comfort level) dictate the service layer of my application. However, I don't want to be biased, and I don't base my decision on a service which I am very familiar with, at the cost of performance. I would like to know what other developers have had success using, and if there is a default standard for iOS service layer development? Are there protocols that are easier to consume than others within iOS? Better ones for the size and/or compression of data? Is there anything wrong with using SOAP? I know it's "big" in comparison to protocols like JSON.

• How can I optimize my development machines files/dirs?

  - by LuxuryMode

  Like any programmer, I've got a lot of stuff on my machine. Some of that stuff is projects of my own, some are projects I'm working on for my employer, others are open-source tools and projects, etc. Currently, I have my files organized as follows: /Code --/development (things I'm sort of hacking on plus maybe libraries used in other projects) --/scala (organized by language...why? I don't know!) --/android --/ruby --/employer_name -- /mobile --/android --/ios --/open-source (basically my forks that I'm pushing commits back upstream from) --/some-awesome-oss-project --/another-awesome-one --/tools random IDE settings sprinkled in here plus some other apps As you can see, things are kind of a mess here. How can I keep things organized in some sort of coherent fashion?

• Automation at GUI or API Level in Scrum

  - by Sani Parwani

  I am a Automation Engineer. I use QTP for Automation. I wanted to know couple of things. In a scrum Project which has 2 weeks of work, how can complete automation be done in that time frame (talking only about the GUI Level)? Similarly, how can API Level of automated testing be accomplished, especially inside a single sprint? And what exactly is API level testing? How to begin with API Testing? I assume QTP is not the tool here certainly.

• Where to draw the line between front end and back end

  - by Twincascos

  I was recently contracted to develop a smarty theme for an automated SOHO phone answering service. The team who had built the backend wouldn't allow me access to any of the back end nor tell me anything about it, their smarty set up, smarty plugins, data base interface api, server set-up, nothing. Nor could I have access to the server nor a beta domain, basically zero co-operation. So I set up a local server with Smarty and built the template based on what I guessed would be their best practice, commented my code like crazy, wrote all the needed javascript, css, and template files. Then I sent them packaged to the backend team and hoped for the best. With half of a project team failing to cooperate or even communicate I am now concerned that they may reply saying that everything is wrong and they may refuse to implement the new front end. I'm curious to know if others encounter this type of situation and what you may have done to protect yourselves.

• Skills for RAD developer.

  - by Janis Peisenieks

  I am about to embark on an exquisite journey. I have applied for an event, where in span of 48 straight hours, strangers meet, throw around some great ideas, decide on teams, and make a working prototype of IT project. All within 48 hours. I anticipate, that this will be very skill and ability intensive experience, and I want to be prepared. Since i will need to develop my part of the code quickly, I have a following question: What would be the most needed skills for these 48 hours? I do know, that things like proper documentation, version control and such are pretty important for a full fledged application/program/web development, but for this span of frantic coding? Background: I am a web developer, so answers applicable to web development would be more appreciated than others.

• How do I morph between meshes that have different vertex counts?

  - by elijaheac

  I am using MeshMorpher from the Unify wiki in my Unity project, and I want to be able to transform between arbitrary meshes. This utility works best when there are an equal number of vertices between the two meshes. Is there some way to equalize the vertex count between a set of meshes? I don't mean that this would reduce the vertex count of a mesh, but would rather add redundant vertices to any meshes with smaller counts. However, if there is an alternate method of handling this (other than increasing vertices), I would like to know.

• What are cons of usage only non-member functions and POD?

  - by Miro

  I'm creating my own game engine. I've read these articles and this question about DOD and there was written to not use member functions and classes. I also heard some criticism to this idea. I can write it using member functions or non-member functions it would be similar. So what are benefits/cons of that approach or when project grows, does any of these approaches give clearer and better manageable code? With POD & non-member functions I don't have to make struct members public I can still use object id outside of engine like OpenGL does with all it's stuff, so It's not about encapsulation. POD - plain old data DOD - data oriented design

• Windows 7 Virtual PC - &ldquo;RPC server unavailable&rdquo;

  - by Kelly Jones

  I use Windows 7 Virtual PC on my current project and I often bring home the files, so I can work some in the evenings.  Since my VHDs are large, I’ll only copy the undo disks, saved state, and virtual machine config files from my external drive.  I copy them to a small portable drive and once I get home, I’ll copy them to a large external drive. I’ve done this for over a year, but recently I started getting an error when I tried to start the VPC after the copying was finished.  It would open the initial window with the progress bar, but eventually the bar would stop, turn red, and then the error “RPC server unavailable” would appear.  When I first started seeing these, I’d try again, but no luck. After some testing, it turns out that my small portable drive is apparently going bad, so it was corrupting the files.  Lucky for me, that I never overwrote my good copies with corrupted copies, at least not at both the office and at home.

• Bug once in a while,but high priority

  - by Shirish11

  I am working on a CNC (computer numerical control) project which cuts shapes into metal with help of laser. Now my problem is once in a while (1-2 times in 20 odd days) the cutting goes wrong or not according to what is set. But this causes loss so the client is not very happy about it. I tried to find out the the cause of it by Including log files Debugging Repeating the same environment. But it wont repeat. A pause and continue operation will again make it to run smoothly with the bug reappearing. How do I tackle this issue? Should I state it as a Hardware Problem?

• Developing a DVR software using a hardware KIT

  - by Leron

  I'm currently thinking about a project for my masters degree graduation. I start researching for options to make my own video streaming software based on a premade hardware kit having not much knowledge about what I'll exactly need that will match my needs. My search led me to the DVR (Digital Video Recorder) cards which seems to be the closest to what I need, but still I can't find out a few basic things so I decide to ask for them here. Currently I haven't find a lot of manufacturers that offers such kits so where I can look and have some options to choose from? There are a lot of DVR products on the market but they already have a software written for them and even if I buy one they just don't give any documentation or sdk's so buying such is not an option I need a DVR card made exactly for software programers and not end users. Are there a preferred manufacturers that provide such kind of devices with good and developer-friendly documentation? Also - I prefer to do all this with Java, is this an option (I think I will make it with .NET too but really prefer Java as a language of choice)
