• Would you consider using training/mentoring from LearnersParadise.com?

  - by HK1

  My initial question deserves some explanation. I signed up for an account at learnersparadise.com. After signing up I couldn't login so I opted to use their "send password" feature. Upon receiving my password in my email I confirmed two things A) They trimmed off 2 of the last digits of my 10-digit password without informing me and saved it that way in their database B) my password is not saved in their database using a one-way hash since they were able to email me my password. I'm quite certain that both of these are perfectly awful programming practices. I suspect that the mentors/trainers at learnersparadise are not necessarily affiliated with the website and it's design since they are basically people like you and me (hopefully more skill than me) who have signed up to become mentors. However, I'm still uncertain about signing up for training/mentoring at a site that uses such poor programming practices themselves? Would you let learnersparadise poor programming practices affect your opinion of their trainers/mentors?

• Stuff every programmer needs while working

  - by Desai Shukla

  I've been tasked with creating a fun and relaxing environment, one thing I know that I want is ergonomic mice and keyboards, others have suggested exercise balls and bands. What is it that every programmer needs while working? What might not be necessary but would be nice to have anyway? Note: this question was asked previously, but has been recommended to be posted here. See this link for the previous responses: http://stackoverflow.com/questions/3911911/stuff-every-programmer-needs-while-working-closed

• Reaching Intermediate Programming Status

  - by George Stocker

  I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

• Is a big name computer science degree worth the cost?

  - by Serplat

  I'm currently in High School and trying to look into what I want to do after I graduate. I know that I will be going to college, and that I want a degree in Computer Science, however, I'm not entirely sure where I want to go (I haven't started the application process yet). I already have built up a decent amount of experience in programming (over the summers I have been hired to program at a local university), and I'm pretty capable of teaching myself most of the material I've come across through either books or web documentation. I'm interested in whether it is worth it to get a degree from a major, big-name computer science university for $50,000 each year, as opposed to going to a local state school for only $20,000. For my Bachelor's degree alone, this would be $120,000 more than the state school. I've also heard that where you get your Bachelor's doesn't matter much if you plan to get a Master's degree. Many people recommend going somewhere like a state school for your Bachelor's, and then try to get into a more major school for your Master's. Has anybody found any truth in this? Basically, is going to a big name computer science school for a Bachelor's degree really worth the added expense?

• Should I forward the a call to .Equals onto .Equals<T>?

  - by Jaimal Chohan

  So, I've got you bog standard c# object, overriding Equalsand implementing IEquatable public override int GetHashCode() { return _name.GetHashCode(); } public override bool Equals(object obj) { return Equals(obj as Tag) } #region IEquatable<Tag> Members public bool Equals(Tag other) { if (other == null) return false; else return _name == other._name; } #endregion Now, for some reason, I used to think that forwarding the calls from Equals into Equals was bad, no idea why, perhaps I read it a long time ago, anyway I'd write separate (but logically same) code for each method. Now I think forwarding Equals to Equals is okay, for obvious reasons, but for the life me I can't remember why I thought it wasn't before. Any thoughts?

• Location of development solutions on disk - Common or upto the individual

  - by dreza

  In our team meeting today a senior member brought up the proposal that we should be having a common location/structure for our development solutions. A couple of his points were: Making it common meant when talking about projects and emailing stuff everyone is on the same wavelength and knows where to look. If there is ever the need to hard code a location path then it will work across all developers pc's. He had a more few points to back up his suggestion but I unfortunately got distracted during the discussion and so didn't hear all of them. I have no issue with the idea and can see it's merits but I was wondering if it is common or even recommended that all developers place their code in the same folder structure. Or do developers like to have the flexibility of location solutions where-ever they want? We currently use SVN for our version control. In this case his recommendation was to place all code in: c:\Work\Development\<Customer>\<project>\Code\<solution>\ the code I guess actual path is irrelevant for this question but added for completeness.

• Hobbyist programmer releasing software with a donate button

  - by espais

  I'd like to start this with a disclaimer that I realize that a full, clear-cut answer should be sought out by a lawyer. I am more so curious about what other users of this community have done Say that I had a small program that I had developed for fun, that I wished to release to the public. I'll drop it out there with one of the various open-source licenses, and probably put it up on SourceForge or Git in case if anybody should ever want to fork/maintain/check out code. Also say that I wanted to accept donations for the project, with absolutely 0 expectation that people will send any money. However, if somebody donated in order to buy me a beer or a pizza for the work that they liked, I would accept gladly. The question, then, is what are the general requirements of accepting donations? Can it go into a personal account with no questions asked as a "gift," or do I need to setup an LLC to avoid any taxation issues? (US citizen here). Again, yes this should be lawyer discussed, but I also know that many projects that I see have the ability to donate, and assume that the community probably has a decent amount of experience in this regard.

• What does "GPL with classpath exception" mean in practice?

  - by Thilo

  Oracle seems to license all their Java-related open source code under the GPL with a classpath exception. From what I understand, this seems to allow to combine these libraries with your own code into products that do not have to be covered by the GPL. How does this work? What are examples of how I can and cannot use these classes? Why was this new license used as opposed to the LGPL, which seems to allow for pretty much the same things, but is better established and understood? What are the differences to the LGPL?

• BDD: Getting started

  - by thom

  I'm starting with BDD and this is my story: Feature: Months and days to days In order to see months and days as days As a date conversion fan I need a webpage where users can enter days and months and convert them to days. I have some doubts ... Should I write my scenarios before coding anything or should I first write a scenario and then write code, write a scenario again and then write code, and so on ... ? If I should write my scenarios before, can my steps be approved and production code still does not get done? When should I do refactoring on my code? After the feature is done or after each scenario implementation?

• open source database project

  - by Jeff V

  What is the best way to build an open source database? I would like to build a database of all vehicles and the related maintenance information (i.e Oil Weight, Quantity, Tire Pressure, Windshield wipers etc). Currently this information is fragmented or just not put on line in an open way. Once collection began I would want to import into a DB and then be able to distribute freely. Is there a process (site or group) that I can start gathering this information in a reliable and verifiable way? Is there any issues that I should watch out for?

• Why is Cocoa using an old version of Unicode? [closed]

  - by Randy Marsh

  While I was searching for something in the Apple docs, I stumble on this: illegalCharacterSet Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard. On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework? My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?

• Changing Filename Case with TortoiseSVN on Windows [migrated]

  - by Brad Turner

  I've been working on a development project using a Windows machine as a test server. Eventually, I'd like the "live" version to end up on a Linux machine. While trying to test on the Linux machine, it became apparent that I needed to change the case of several file names as Windows was case insensitive but Linux wasn't. When I changed the file name case in Windows, TortoiseSVN recognized that the file hand changed and marked my folders appropriately. However, when I tried to commit my changes, not only did TortoiseSVN tell me that no changes had been made, but it had actually reverted all of the file name changes I had made back to their original case. My question is, is there a simple way to alter the file name case from a Windows PC and have the changes appear in my repository? I'd like to avoid any kind of delete, commit, replace, commit scenario to keep my commits tidy if possible. Thanks!

• Java and web pages

  - by Filippo

  Hello everyone and thank you in advance for the answers. I have a question concerning not how to do something, but with which instruments. Let's say, I want to write a simple application in Java that connects to a news website (e.g. CNN), parses the html document and prints on screen the news. Another example : my application retrieves and prints on screen soccer results from Eurosports. What do I need to do that? External libraries? Or maybe what I'm looking for is already included in JavaEE? Could this be helpful? http://jsoup.org/<< Thank you everyone again and have a nice day.

• Scrum Board for a distributed team

  - by Falcon

  I am looking for recommendations on a digital Scrum Board which can be shared over the internet. I imagine something like a big tablet on which you can draw and which remote users can access, too. I dislike Scrum software because I think one major benefit of a Scrum Board is its physical presence. It should be hard to ignore. The best solution would be two big tablets on which you can draw and which can be synchronized. Has anyone got product recommendations for something like this? Or would you rather use a software? Kind regards, Falcon

• How does PHP internally represent strings?

  - by Jim Thio

  UTF8? UTF16? Do strings in PHP also keep track of the encoding used? Let's look at this script for example. Say I run: $original = "??????????????"; What actually happens? Obviously I think $original will not contain just 7 characters. Those glyphs must each be represented by several bytes there. Then I do: $converted = mb_convert_encoding ($original , "UTF-8"); What will happen to $converted? How will $converted be different from $original? Will it be just the exact same byte sequence as $original but with a different encoding?

• How to keep a generic process unique?

  - by Steve Van Opstal

  I'm currently working on a project that makes connection between different banks which send us information on which that project replies. A part of that project configures the different protocols that are used (not every bank uses the same protocol), this runs on a separate server. These processes all have unique id's which are stored in a database. But to save time and money on configurations and new processes, we want to make a generic protocol that banks can use. Because of PCI requirements we have to make a separate process for every bank we connect to. But the generic process has only 1 unique identifier and therefor we cannot keep them apart. Giving every copy of that process a different identifier is as I see it impossible because they run entirely separate. So how do I keep my generic process unique?

• It's hard to judge your own product. Is there a name for this issue?

  - by Epicmaster

  I was just talking to my partner about how hard it is to personally judge how good your product is after a while because you use it so often. You literally spend hours on your computer doing nothing but work on this Consumer Facing application, and you start to feel a little fatigue of using it over and over and over, at least a hundred times a day. You get scared this fatigue may mean the product you are building may have the same effect on the users and might mean you are doing something wrong. Is there a name for this in product development? For the fact that as a designer+ programmer+everything else, your product might not suck as much as you think simply because you spend way too much time with it, or a variation of this?

• Using Interlocked.Exchange(ref Enum, 1) to prevent re-entrancy [migrated]

  - by makerofthings7

  What options do I have for pending work that can't acquire a lock via the following sample? System.Threading.Interlocked.CompareExchange<TrustPointStatusEnum> (ref tp.TrustPointStatus, TrustPointStatusEnum.NotInitalized,TrustPointStatusEnum.Loading); Based on my research think I have the following options: I can use Threading.SpinWait (for very quick IO tasks) at the cost of CPU I can use Sleep() which has an unreliable wake up time I'm not sure of any other option, but what I want to make sure of is that all these options work with the .NET 4 async and await keywords, especially if I use Task to run them on a background thread

• How can I convince my company to move to MVC?

  - by guanome

  I currently write web apps using asp.net web forms and getting my company to move to another technology is like [insert funny line here]. I would really like to start writing apps using MVC, but they fear any type of change. How is the best way to convince/ease them into using MVC? I guess this can go for moving to any new technology. Update Decided to go the rogue developer route and just started using it. I recreated a small app in MVC and learned the ropes that way, and moved up from there.

• Selling an open source project: some issues

  - by Sander

  I am the creator / main developer of a small sized open source (PHP) project (GPL3). Currently there is a development team of 3 people (me included). This team has been quite active for some time, but since almost 2 years not much has happened. I myself have decided I want to stop working on the project, but I can't just leave the project because I care about it and I know if I abandon it, it will just be a matter of time before the project completely dies. At this moment, there are still some users and the project is only slightly out-of-date. So I'm thinking about selling the whole project. Of course I'd need to get consent of the other developers, but for now I'm assuming that's not a big problem. So at this moment I have 2 questions: 1) If the project would be sold to a commercial party, would it be possible for them to convert the project to closed source? I would prefer to sell the project to a company/organization that would continue the development under an open source license. 2) Does anyone have any tips to find interested parties? I don't know if I just want to put up a "For Sale" sign on the website of the project. Maybe someone has experience with a comparable situation. Ok guys, thanks in advance!

• Application use on website

  - by Palmer

  Is there a good way to run a C# application on clientside in lieu of JavaScript? I have done some front end work with JavaScript and backend C# for web developing at an old job, but I am interested in hosting a website myself soon. I have a C# application I would like to be open source, but before people care to download I'd like them to be able to use it. At its basic level it's a simple text editor, but there's much more to it in the nitty gritty. I could write it in JavaScript, but it would require me to keep documentation and up to date changes on JavaScript and C# in that case. I was thinking of creating an AJAX panel and somehow loading my winform application into a frame, but I don't know how or what words to google because I've never done it before except AJAX.

• Why does working processors harder use more electrical power?

  - by GazTheDestroyer

  Back in the mists of time when I started coding, at least as far as I'm aware, processors all used a fixed amount of power. There was no such thing as a processor being "idle". These days there are all sorts of technologies for reducing power usage when the processor is not very busy, mostly by dynamically reducing the clock rate. My question is why does running at a lower clock rate use less power? My mental picture of a processor is of a reference voltage (say 5V) representing a binary 1, and 0V representing 0. Therefore I tend to think of of a constant 5V being applied across the entire chip, with the various logic gates disconnecting this voltage when "off", meaning a constant amount of power is being used. The rate at which these gates are turned on and off seems to have no relation to the power used. I have no doubt this is a hopelessly naive picture, but I am no electrical engineer. Can someone explain what's really going on with frequency scaling, and how it saves power. Are there any other ways that a processor uses more or less power depending on state? eg Does it use more power if more gates are open? How are mobile / low power processors different from their desktop cousins? Are they just simpler (less transistors?), or is there some other fundamental design difference?

• Functional programming compared to OOP with classes

  - by luckysmack

  I have been interested in some of the concepts of functional programming lately. I have used OOP for some time now. I can see how I would build a fairly complex app in OOP. Each object would know how to do things that object does. Or anything it's parents class does as well. So I can simply tell Person().speak() to make the person talk. But how do I do similar things in functional programming? I see how functions are first class items. But that function only does one specific thing. Would I simply have a say() method floating around and call it with an equivalent of Person() argument so I know what kind of thing is saying something? So I can see the simple things, just how would I do the comparable of OOP and objects in functional programming, so I can modularize and organize my code base? For reference, my primary experience with OOP is Python, PHP, and some C#. The languages that I am looking at that have functional features are Scala and Haskell. Though I am leaning towards Scala. Basic Example (Python): Animal(object): def say(self, what): print(what) Dog(Animal): def say(self, what): super().say('dog barks: {0}'.format(what)) Cat(Animal): def say(self, what): super().say('cat meows: {0}'.format(what)) dog = Dog() cat = Cat() dog.say('ruff') cat.say('purr')

• What is (are) the most useful technique/visualization for overall project status?

  - by Wayne Werner

  For reasons "above my pay grade", we're developing an issue/project tracking system where I work (similar to Trac, FogBugz, etc). The managers want a useful tool to be able to track the overall health of the project (e.g. How much time left, how are we performing vs estimates) and one of the features that has been requested is some type of critical path support and visualization. The logic explained to me is that they want to be sure that at least the most important pieces of the project are currently being worked on. The initial idea was that we would create task-based dependencies. My understanding of project management tells me that this kind of granular approach is unnecessary - having milestones with specific deadlines/dependencies is much more useful. I would like to know what are the most useful techniques and "pretty pictures" you've seen/used for project development. Having objective data would be best, but somewhat subjective data is helpful too.

• CS subjects that an undergraduate must know.

  - by Karl

  In college, I was never interested in theory. I never read it. No matter how much I tried, I was unable to read stuff and not know what was actually happening practically. Like for example, in my course on automata theory, my professor told me everything possibly related to the mathematical aspect of it, but not even once did he mention where it would be used practically. This is just an example. I managed to pass my college and interned with a company also, where I did a project and thankfully they didn't bother about my grades, as they were above average. Now, I am interested in knowing what subjects should a CS student must absolutely and positively be aware of? Subjects that can have relevance in the industry. This is because I have some free time on my hands and it would help me better to have a good understanding of them. What are your suggestions? Like for one, algorithms is one subject.
