• Should I list this work experience on my resume? [closed]

  - by Phoenix

  I am currently working at a company. I did an internship before this job with a prestigious company and project itself was challenging but it was in the initial phases and hence there were no tight schedules and we ended up doing brainstorming for the first month and the 2nd month actually setting up our hardware, which is linux servers in lab and a cluster administrator for the servers. And then i wrote an addin task which runs on the server and uses existing API to collect some statistics from the the servers in the cluster and feeding them into another entity which is basically an algorithm that calculates how the load on the servers should be automatically balanced. Neither of these things went into production by the time I left the company and I'm not even sure of their current state. Does it make sense to include it in my resume then? I also worked as a software engineer right out of school at another prestigious company for 9 months. I was involved in some bug fixes before the product launched and I don't even recollect the exact fixes I made to the product. So, will it make sense to have these experiences on my resume ? Will people question me about them and will saying it was bug fixes and mentioning what kind of fixes suffice as enough to justify my work ex there ?

• Can I use a project code which has New BSD license but uses a GPL license library?

  - by Alok Kulkarni

  I want to use the ICSOpenVpn project source code in my commercial application. If we see the ICSOpenVpn project, it states that its license is New BSD but the libopenvpn.so library it uses is under GNU GPLv2 license. As per FAQ for version 2 of GNU GPL "If a library is released under the GPL (not the LGPL), does that mean that any program which uses it has to be under the GPL?" The answer says: "Yes, because the program as it is actually run includes the library." Also, how could ICSOpenVpn change the license to New BSD?

• Best way to use GIT to maintain web application template

  - by Darren

  I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

• What reasons are there for not using a third party version control service?

  - by Earlz

  I've recently noticed a bit of a trend for my projects as of late. I use to run my own SVN server on my VPS, but recently the nail went in the coffin for that when I got my last project migrated from my server to a Mercurial repo on Bitbucket. What are some of the ramifications to this? (disregarding the change in version control systems) It seems like there has been a huge explosion in version control hosting, and companies like Bitbucket even offer private repos for free, and Github and other such services are extremely cheap now. Also, by using them you get the benefit of their infrastructure's speed and stability. What reasons are there these days to host your own version control? The only real reason I can think of is if your source code is super top secret.

• Is shipping a Clojure desktop app realistic?

  - by Cedric Martin

  I'm currently shipping a desktop Java application. It is a plain old Java 5 Java / Swing app and so far everything worked nicely. Java 5 was targetted because some users were on OS X version / computers that shall never have Java 6 (we may lift this limitation soon and switch to a newer Java and simply abandoning my users stuck with Java 5). I'm quickly getting up to speed with Clojure but I haven't really done lots of Clojure-to-Java and Java-to-Clojure yet and I was wondering if it was realistic to ship a Clojure desktop application instead of a Java application? The application I'm shipping is currently about 12 MB with all the .jar so adding Clojure doesn't seen to be too much of an issue. My plan would be to have Clojure call Java APIs: my application is already divided in several independent jars. If I understand correctly calling Clojure from Java is harder than calling Java code from Clojure which is why I'd basically rewrite all the UI (part of the UI, mixing Swing components and self-made BufferedImages needs to be rewritten anyway due to the rise of retina display), and do all the 'wiring' from Clojure. So that's the problem I'm facing: is it realistic to ship a Clojure desktop app? (it certainly doesn't seem to be very widespread but then shipping plain Java desktop apps ain't that common either and I'm doing it anyway) Technically, what would need to be done? (compared to shipping a Java app)

• Improving grepping over a huge file performance

  - by rogerio_marcio

  I have FILE_A which has over 300K lines and FILE_B which has over 30M lines. I created a bash script that greps each line in FILE_A over in FILE_B and writes the result of the grep to a new file. This whole process is taking over 5+ hours. I'm looking for suggestions on whether you see any way of improving the performance of my script. I'm using grep -F -m 1 as the grep command. FILE_A looks like this: 123456789 123455321 and FILE_B is like this: 123456789,123456789,730025400149993, 123455321,123455321,730025400126097, So with bash I have a while loop that picks the next line in FILE_A and greps it over in FILE_B. When the pattern is found in FILE_B i write it to result.txt. while read -r line; do grep -F -m1 $line 30MFile done < 300KFile Thanks a lot in advance for your help.

• Design patterns and multiple programming languages

  - by Eduard Florinescu

  I am referring here to the design patterns found in the GOF book. First, how I see it, there are a few peculiarities to design pattern and knowing multiple languages, for example in Java you really need a singleton but in Python you can do without it you write a module, I saw somewhere a wiki trying to write all GOF patterns for JavaScript and all the entries were empty, I guess because it might be a daunting task to do that adaptation. If there is someone who is using design patterns and is programming multiple languages supporting the OOP paradigm and can give me a hint on how should I approach design patterns. An approach that might help me in all languages I use(Java, JavaScript, Python, Ruby): Can I write good application without knowing exactly the GOF design patterns or I might need just some of them which might be crucial and if yes which one, are there alternatives to GOF for specific languages, and should a programmer or a team make their own design patterns set?

• Empirical evidence for choice of programming paradigm to address a problem

  - by Graham Lee

  The C2 wiki has a discussion of Empirical Evidence for Object-Oriented Programming that basically concludes there is none beyond appeal to authority. This was last edited in 2008. Discussion here seems to bear this out: questions on whether OO is outdated, when functional programming is a bad choice and the advantages and disadvantages of AOP are all answered with contributors' opinions without reliance on evidence. Of course, opinions of established and reputed practitioners are welcome and valuable things to have, but they're more plausible when they're consistent with experimental data. Does this evidence exist? Is evidence-based software engineering a thing? Specifically, if I have a particular problem P that I want to solve by writing software, does there exist a body of knowledge, studies and research that would let me see how the outcome of solving problems like P has depended on the choice of programming paradigm? I know that which paradigm comes out as "the right answer" can depend on what metrics a particular study pays attention to, on what conditions the study holds constant or varies, and doubtless on other factors too. That doesn't affect my desire to find this information and critically appraise it. It becomes clear that some people think I'm looking for a "turn the crank" solution - some sausage machine into which I put information about my problem and out of which comes a word like "functional" or "structured". This is not my intention. What I'm looking for is research into how - with a lot of caveats and assumptions that I'm not going into here but good literature on the matter would - certain properties of software vary depending on the problem and the choice of paradigm. In other words: some people say "OO gives better flexibility" or "functional programs have fewer bugs" - (part of) what I'm asking for is the evidence of this. The rest is asking for evidence against this, or the assumptions under which these statements are true, or evidence showing that these considerations aren't important. There are plenty of opinions on why one paradigm is better than another; is there anything objective behind any of these?

• Concerns on first ASP.NET cloud application

  - by RPK

  I am writing a small ASP.NET Web Application. My worries are that I want to keep the architecture same giving me the option to install it on an Intranet or on a Cloud Platform. I am not using MVC but lately learned that Azure only supports ASP.NET MVC applications. I want to know whether ASP.NET Web Forms application work on Azure/AppHarbor or not. Do I need to convert this application to MVC if Web Forms is not supported? Will the same application run on Intranet as well?

• When to use abstract classes instead of interfaces and extension methods in C#?

  - by Gulshan

  "Abstract class" and "interface" are similar type of ideas, while interface being more abstract. One need of abstract classes was to provide method implementations for the derived classes. But in C#, that need has also been reduced by lately introduced extension methods. So, in C#, when should we use abstract classes instead of using interfaces and extension methods associated with the interface? And now, we can use 'Properties' in interfaces also. A notable example of interface+ extension methods is the Heavily used IEnumerable and it's helper methods. You use Linq and it's all by this extension methods!

• How can I boost my C# learning curve?

  - by MSU

  I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

• Communication between WCF service [library] and Self-host [Winform]

  - by Mur Haf Soz

  Introduction: I have a WCF service library and a self-host Winform. Service features is File explorer including (copy, move, delete, new folder, delete... etc) and Task Manager (run, kill, update list). Then now I want to add other features like chatting between self-host and client, send an image from client to self-host so when it received, it is shown in a pictureBox in a new form. Till now I have two endpoints for (Task Manager, File Manager) that runs under one service "MainService". And I set up all the connections using DotNet 4.0 WCF Configuration and Wizards, and I'm using netTcpBinding. Problem: I need to know how to communicate with between WCF service lib and self-host, so I can append a received chat from client on self-host form's textbox TextBoxChat. And also call a client callback from self-host when Send button clicked, to send the message from self-host textbox TextBoxMessage. Let's say this's self-host ChatForm So is it possible to do that in WCF? I would prefer to run ChatEndpoint under MainService, so all Endpoints use one port.

• Looking for a simple to use email server that can be programmatically (preferably remotely) used

  - by sr2222

  I've been poking around the internet for much of the day, but I can't seem to find a good server to fit my needs. What I need is a simple to use and deploy (pref open source) lightweight email server that I can create users on programmaticly that has IMAP or POP support. I'd prefer something with an existing service interface, but if I have to write a REST API on top of an easy to use API, that's acceptable. The purpose of this tool will be to allow a test automation framework to create new email accounts and retrieve email sent to those addresses. I need text, html, and possibly attachment support as well. Perhaps it's my noobishness, but I can't really suss out the details from the documentation on the servers available out there to figure out which fit my needs.

• Introducing Programming To a Mathematician

  - by ell

  I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

• Iphone/Android app – chatroom development – what framework & hosting needs?

  - by MikaelW

  I have some experience regarding IPhone and Android development but I am now struggling to solve a new class of problem: apps that involve a client/server chatroom feature. That is, an app when people can exchange text over the internet, and without having the app to constantly “pull” content from the server. So that problem can’t be solved with a normal php/mysql website, there must be some kind of application running on a server that is able to send message from the server to the phone, rather than having the phone to check for new messages every 10 seconds… So I’m looking for ways to solve the different problems here: What framework should I use on the two sides (phone / server)? It should be some kind of library that doesn’t prevent me to write paid apps. It should also be possible to have the same server for the Iphone and android version of the app. What server / hosting solution do I need with what sort of features, I just have no experience regarding server application that can handle and initiate multiple connections and are hosted on hardware that is always online I tried to find resources online but couldn’t so far, either the libraries had the wrong kind of license/language or I just didn’t understand… Sometimes there were nice tutorial but for different needs such as peer2peer chat over local network… Same with the server and the hosting problem, not sure where to start really, I’m calling for help and I promise I will complete this page with notes about the experience I will get :-) Obviously the ideal would be to find a tutorial I missed that include client code, server code and a free scalable server… That being said, If I see something as good, it probably means that I have eaten the wrong kind of mushroom again… So, failing that, any pointer which might help me toward that quest, would be greatly appreciated. Thanks in advance. Mikael

• Removing hard-coded values and defensive design vs YAGNI

  - by Ben Scott

  First a bit of background. I'm coding a lookup from Age - Rate. There are 7 age brackets so the lookup table is 3 columns (From|To|Rate) with 7 rows. The values rarely change - they are legislated rates (first and third columns) that have stayed the same for 3 years. I figured that the easiest way to store this table without hard-coding it is in the database in a global configuration table, as a single text value containing a CSV (so "65,69,0.05,70,74,0.06" is how the 65-69 and 70-74 tiers would be stored). Relatively easy to parse then use. Then I realised that to implement this I would have to create a new table, a repository to wrap around it, data layer tests for the repo, unit tests around the code that unflattens the CSV into the table, and tests around the lookup itself. The only benefit of all this work is avoiding hard-coding the lookup table. When talking to the users (who currently use the lookup table directly - by looking at a hard copy) the opinion is pretty much that "the rates never change." Obviously that isn't actually correct - the rates were only created three years ago and in the past things that "never change" have had a habit of changing - so for me to defensively program this I definitely shouldn't store the lookup table in the application. Except when I think YAGNI. The feature I am implementing doesn't specify that the rates will change. If the rates do change, they will still change so rarely that maintenance isn't even a consideration, and the feature isn't actually critical enough that anything would be affected if there was a delay between the rate change and the updated application. I've pretty much decided that nothing of value will be lost if I hard-code the lookup, and I'm not too concerned about my approach to this particular feature. My question is, as a professional have I properly justified that decision? Hard-coding values is bad design, but going to the trouble of removing the values from the application seems to violate the YAGNI principle. EDIT To clarify the question, I'm not concerned about the actual implementation. I'm concerned that I can either do a quick, bad thing, and justify it by saying YAGNI, or I can take a more defensive, high-effort approach, that even in the best case ultimately has low benefits. As a professional programmer does my decision to implement a design that I know is flawed simply come down to a cost/benefit analysis?

• Somewhere to get inspiration - Pair up the creative with the tech

  - by Morten Bergfall

  I am a somewhat green developer; some work experience, last year of school. As most of you, I am constantly working on an assortment of personal projects. Since my mind often has a somewhat drifting characteristic; I am not always able to keep the projects in check. After some time they all exhibit the moral fiber of Vikings, harlots and chain-letter-knitters. This includes constant forking, round-abouting, eating of school assignments of rather mundane, and hence pretty yawn-inducing, specifications, and of course quite a bit of gathering of folder dust. Well, on to my question....is there a place, forum... or something with the purpose of linking people with ideas to the people actually being able to bring said ideas to life? Of course, I know of the professional ones, like rent-a-coder and such. And there seem to be a lot of open source projects available for participation. What I'm looking for doesn't really fit into any of those categories....the form would be somewhat like rent-a-coder, but this is ideas&inspiration, not bubble-sort-my-quarterly-for-a-buck. The possibilities for developing bonds, spicy code, and plain old fun seem quite possible.As I see it, the main benefit would be that we (that is the tech-flipside of the proverbial eCoin) get something worthwhile to do, rather than squeeze the last creative grain out of our code-heavy brains.To give it some perspective...: My last project consists of an absurd jQuery-plugin that includes animated png-robots migrating from Google Earth to drag a html-element of your choosing onto the map, where it gets color, for so to be dragged back by this poorly animated robot.... Often, the line between the creative and the tech is blurred, to say the least. I wouldn't think that would be a problem. Think someone who has developed a nifty little windows application, then sees possibility for a broader use, perhaps some sort of networking functionality. This fellow sadly lacks the skill to implememet this. So he, she or it would then seek a developer with the know-how and they could complete this project together. So, do any of you know of such a place, or can nudge in the right direction? And yes, I understand completely that I should be dedicating myself to doing school work, or applying for mundane developer positions, so please.... :-) UPDATE Sadly, I'm situated in Oslo, Norway, and the number of developers are somewhat limited...and I have had quite some ahem personality issues with the ones who are available ;-) So I feel I must go deeper; search the multitude of the web...

• C/C++: Who uses the logical operator macros from iso646.h and why?

  - by Jaime Soto

  There has been some debate at work about using the merits of using the alternative spellings for C/C++ logical operators in iso646.h: and && and_eq &= bitand & bitor | compl ~ not ! not_eq != or || or_eq |= xor ^ xor_eq ^= According to Wikipedia, these macros facilitate typing logical operators in international (non-US English?) and non-QWERTY keyboards. All of our development team is in the same office in Orlando, FL, USA and from what I have seen we all use the US English QWERTY keyboard layout; even Dvorak provides all the necessary characters. Supporters of using the iso646.h macros claim we should them because they are part of the C and C++ standards. I think this argument is moot since digraphs and trigraphs are also part of these standards and they are not even supported by default in many compilers. My rationale for opposing these macros in our team is that we do not need them since: Everybody on our team uses the US English QWERTY keyboard layout; C and C++ programming books from the US barely mention iso646.h, if at all; and new developers may not be familiar with iso646.h (this is expected if they are from the US). /rant Finally, to my set of questions: Does anyone in this site use the iso646.h logical operator macros? Why? What is your opinion about using the iso646.h logical operator macros in code written and maintained on US English QWERTY keyboards? Is my digraph and trigraph analogy a valid argument against using iso646.h with US English QWERTY keyboard layouts? EDIT: I missed two similar questions in StackOverflow: Is anybody using the named boolean operators? Which C++ logical operators do you use: and, or, not and the ilk or C style operators? why?

• Syntactic sugar in PHP with static functions

  - by Anna

  The dilemma I'm facing is: should I use static classes for the components of an application just to get nicer looking API? Example - the "normal" way: // example component class Cache{ abstract function get($k); abstract function set($k, $v); } class APCCache extends Cache{ ... } class application{ function __construct() $this->cache = new APCCache(); } function whatever(){ $this->cache->add('blabla'); print $this->cache->get('blablabla'); } } Notice how ugly is this->cache->.... But it gets waay uglier when you try to make the application extensible trough plugins, because then you have to pass the application instance to its plugins, and you get $this->application->cache->... With static functions: interface CacheAdapter{ abstract function get($k); abstract function set($k, $v); } class Cache{ public static $ad; public function setAdapter(CacheAdapter $a){ static::$ad = $ad; } public static function get($k){ return static::$ad->get($k); } ... } class APCCache implements CacheAdapter{ ... } class application{ function __construct(){ cache::setAdapter(new APCCache); } function whatever() cache::add('blabla', 5); print cache::get('blabla'); } } Here it looks nicer because you just call cache::get() everywhere. The disadvantage is that I loose the possibility to extend this class easily. But I've added a setAdapter method to make the class extensible to some point. I'm relying on the fact that I won't need to rewrite to replace the cache wrapper, ever, and that I won't need to run multiple application instances simultaneously (it's basically a site - and nobody works with two sites at the same time) So, am doing it wrong?

• Is comparing an OO compiler to a SQL compiler/optimizer valid?

  - by Brad

  I'm now doing a lot of SQL development at my new job where as before I was doing Object Oriented desktop app stuff. I keep running across very large scripts (thousands of lines) and wanting to refactor in some way. I am seeing that SQL is a different sort of beast and it's probably fine to have these big scripts for the most part but while explaining this to me people are also insisting that the whole idea of refactoring is bad. That stuff like the .NET compiler are actually burdened by refactored code and that a big wall of code is more efficient and better design than code designed for reuse, readability and scalability. The other argument is that OO compilers are almost dangerously inefficient and don't have efficient memory management or runs too many CPU instructions compared to older "simpler" compilers and compared to SQL. Are these valid complaints? Even if some compiler like a C compiler is modestly more "efficient" (whatever that means on this high of a level without seeing code) would you want to write applications in C over C# or Java? Is comparing an OO compiler to a SQL compiler/optimizer even valid?
