• How to tackle a boss who thinks everybody in this world is wrong except him?

  - by anon

  I mean seriously, how do you tackle a guy who even changes our variable names (even though they are reasonable) and sends back the code (after review) like 4 times? I know for sure I'm not that bad a developer! So many times, he enforces his ideals, which are not even best practices in the industry! I point out to him whatever link I can find on the internet trying to prove my point, but in the end he uses his authority to shut us out. Sick and tired. Frustrated. Do I have any way out other than quitting the job?

• Customizing the NUnit GUI for data-driven testing

  - by rwong

  My test project consists of a set of input data files which is fed into a piece of legacy third-party software. Since the input data files for this software are difficult to construct (not something that can be done intentionally), I am not going to add new input data files. Each input data file will be subject to a set of "test functions". Some of the test functions can be invoked independently. Other test functions represent the stages of a sequential operation - if an earlier stage fails, the subsequent stages do not need to be executed. I have experimented with the NUnit parametrized test case (TestCaseAttribute and TestCaseSourceAttribute), passing in the list of data files as test cases. I am generally satisfied with the the ability to select the input data for testing. However, I would like to see if it is possible to customize its GUI's tree structure, so that the "test functions" become the children of the "input data". For example: File #1 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest File #2 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest This will be useful for identifying the stage that failed during the processing of a particular input file. Is there any tips and tricks that will enable the new tree layout? Do I need to customize NUnit to get this layout?

• Good library for search text tokenization

  - by Chris Dutrow

  Looking to tokenize some text in the same or similar way in which a search engine would do it. The reason we are doing this is so that we can run some statistical analysis on the tokens. The language we are using is python, so would prefer a library in that language, but could probably set something up to use another language if necessary. Example Original token: We have some great burritos! More simplified: (remove plurals and punctuation) We have some great burrito Even more simplified: (remove superfluous words) great burrito Best: (recognize positive and negative meaning): burrito -positive-

• OOP for unit testing : The good, the bad and the ugly

  - by Jeff

  I have recently read Miško Hevery's pdf guide to writing testable code in which its stated that you should limit your classes instanciations in your constructors. I understand that its what you should do because it allow you to easily mock you objects that are send as parameters to your class. But when it comes to writing actual code, i often end up with things like that (exemple is in PHP using Zend Framework but I think it's self explanatory) : class Some_class { private $_data; private $_options; private $_locale; public function __construct($data, $options = null) { $this->_data = $data; if ($options != null) { $this->_options = $options; } $this->_init(); } private function _init() { if(isset($this->_options['locale'])) { $locale = $this->_options['locale']; if ($locale instanceof Zend_Locale) { $this->_locale = $locale; } elseif (Zend_Locale::isLocale($locale)) { $this->_locale = new Zend_Locale($locale); } else { $this->_locale = new Zend_Locale(); } } } } Acording to my understanding of Miško Hevery's guide, i shouldn't instanciate the Zend_Local in my class but push it through the constructor (Which can be done through the options array in my example). I am wondering what would be the best practice to get the most flexibility for unittesing this code and aswell, if I want to move away from Zend Framework. Thanks in advance

• How could there still not be a mysqldb module for Python 3?

  - by itsadok

  This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• Are Java certifications important for an architect role?

  - by Tahir Akram

  My this question is career path related. I want to know how much Java Certifications (SCJP, SCWCD and others) are important for an architect position. If a person posses a good experience in Java development and want to pursue his career on architect level, do you guys think he need to have certification on his CV. If he has never worked on lead developer roles? If you conducting my interview for an architect position. And I have worked as a Java web developer in different teams having 5 years of exp. Never lead any. And I am having certification badges on my CV. How can a developer make his career path towards being an architect in a team?

• Can AfferoGPLv3 code be used in GPLv3 code?

  - by Karel Bílek

  Can software with AGPLv3 license be used with GPLv3 project? Can the resulting project be GPLv3, or must it have the special requirements of AGPLv3? I am not very smart from clause 13 of GLPv3 that mentions AGPLv3. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. Must the resulting, combined work be AGPLv3 or not?

• Domain Models (PHP)

  - by Calum Bulmer

  I have been programming in PHP for several years and have, in the past, adopted methods of my own to handle data within my applications. I have built my own MVC, in the past, and have a reasonable understanding of OOP within php but I know my implementation needs some serious work. In the past I have used an is-a relationship between a model and a database table. I now know after doing some research that this is not really the best way forward. As far as I understand it I should create models that don't really care about the underlying database (or whatever storage mechanism is to be used) but only care about their actions and their data. From this I have established that I can create models of lets say for example a Person an this person object could have some Children (human children) that are also Person objects held in an array (with addPerson and removePerson methods, accepting a Person object). I could then create a PersonMapper that I could use to get a Person with a specific 'id', or to save a Person. This could then lookup the relationship data in a lookup table and create the associated child objects for the Person that has been requested (if there are any) and likewise save the data in the lookup table on the save command. This is now pushing the limits to my knowledge..... What if I wanted to model a building with different levels and different rooms within those levels? What if I wanted to place some items in those rooms? Would I create a class for building, level, room and item with the following structure. building can have 1 or many level objects held in an array level can have 1 or many room objects held in an array room can have 1 or many item objects held in an array and mappers for each class with higher level mappers using the child mappers to populate the arrays (either on request of the top level object or lazy load on request) This seems to tightly couple the different objects albeit in one direction (ie. a floor does not need to be in a building but a building can have levels) Is this the correct way to go about things? Within the view I am wanting to show a building with an option to select a level and then show the level with an option to select a room etc.. but I may also want to show a tree like structure of items in the building and what level and room they are in. I hope this makes sense. I am just struggling with the concept of nesting objects within each other when the general concept of oop seems to be to separate things. If someone can help it would be really useful. Many thanks

• What are the advantages and disadvantages of having a subdomain for each user account?

  - by Sathish Manohar

  I notice two types of design used in web applications, some with a particular subdomain for users contents, and some with same URL structure for all the accounts. Ex: unique.domain.com and another_unique.domain.com for subdomains for sites like blogspot, wordpress, basecamp etc. while in the other approach domain.com/action1 and domain.com/action2 the content is shown according to the user logged in, but the URL is same for every user. What are main differences between both of these kind of design?

• Functional programming readability

  - by Jimmy Hoffa

  I'm curious about this because I recall before learning any functional languages, I thought them all horribly, awfully, terribly unreadable. Now that I know Haskell and f#, I find it takes a little longer to read less code, but that little code does far more than an equivalent amount would in an imperative language, so it feels like a net gain and I'm not extremely practiced in functional. Here's my question, I constantly hear from OOP folks that functional style is terribly unreadable. I'm curious if this is the case and I'm deluding myself, or if they took the time to learn a functional language, the whole style would no longer be more unreadable than OOP? Has anybody seen any evidence or got any anecdotes where they saw this go one way or another with frequency enough to possibly say? If writing functionally really is of lower readability than I don't want to keep using it, but I really don't know if that's the case or not..

• Overloading interface buttons, what are the best practices?

  - by XMLforDummies

  Imagine you'll have always a button labeled "Continue" in the same position in your app's GUI. Would you rather make a single button instance that takes different actions depending on the current state? private State currentState = State.Step1; private ContinueButton_Click() { switch(currentState) { case State.Step1: DoThis(); currentState = State.Step2; break; case State.Step2: DoThat(); break; } } Or would you rather have something like this? public Form() { this.ContinueStep2Button.Visible = false; } private ContinueStep1Button_Click() { DoThis(); this.ContinueStep1Button.Visible = false; this.ContinueStep2Button.Visible = true; } private ContinueStep2Button_Click() { DoThat(); }

• Efficient Trie implementation for unicode strings

  - by U Mad

  I have been looking for an efficient String trie implementation. Mostly I have found code like this: Referential implementation in Java (per wikipedia) I dislike these implementations for mostly two reasons: They support only 256 ASCII characters. I need to cover things like cyrillic. They are extremely memory inefficient. Each node contains an array of 256 references, which is 4096 bytes on a 64 bit machine in Java. Each of these nodes can have up to 256 subnodes with 4096 bytes of references each. So a full Trie for every ASCII 2 character string would require a bit over 1MB. Three character strings? 256MB just for arrays in nodes. And so on. Of course I don't intend to have all of 16 million three character strings in my Trie, so a lot of space is just wasted. Most of these arrays are just null references as their capacity far exceeds the actual number of inserted keys. And if I add unicode, the arrays get even larger (char has 64k values instead of 256 in Java). Is there any hope of making an efficient trie for strings? I have considered a couple of improvements over these types of implementations: Instead of using array of references, I could use an array of primitive integer type, which indexes into an array of references to nodes whose size is close to the number of actual nodes. I could break strings into 4 bit parts which would allow for node arrays of size 16 at the cost of a deeper tree.

• Why does it take so long to finalize the HTML 5 spec?

  - by EpsilonVector

  I was reading this and one sentence caught my eye (emphasis mine): So Ian Hickson, XHTML’s biggest critic, fathered HTML 5, an action-oriented toddler specification that won’t reach adulthood until 2022, although some of it can be used today. Is that true? Is that really the HTML 5 development cycle? Why is it taking so long? What makes it so difficult to get right that it won't be final until 11 years from now?

• Is there value in having technical authors in a software team?

  - by Desolate Planet

  During my 5 years in IT as a software developer, I've noticed that developers have a strong distaste towards doing any documentation. The act of taking screenshots and creating documentation seems to be a painful and time consuming experience. In one company I worked for, we had a technical documentation team with two technical authors and they developed all the user guides for our customers. In other companies where I've suggested hiring a technical author, I've been told they are not worth the money, but I'm a little unsure if that rings true. Is it better to have developers stop coding and take half a day to do screenshots and create the various guides or is it worth hiring someone who handles such tasks?

• What was the first consumer-oriented hardware/software solution?

  - by Maksee

  We all know the story of the personal computer as a consumer-oriented product. But I just thought that real end user solution should have appeared before that time. So a product that was probably expensive, but allowed using it as a service charging for it, for example computer-terminal for transport time-table access or game machine. On the other site, the video terminals as we know them appeared not so long ago. So if there was something like this, this could be hardware/software most likely offering no interactivity, but probably printing some information based on user actions.

• what is the Web development process efficiency judgment criteria

  - by Ahmed safan

  I'm working as a web developer and I want to be able to determine if I'm efficient. Does this include the how long it take to accomplish tasks such as: Server side code for the site logic with one language or multiple php,asp,asp.net. Client side code like javascript with jquery for ajax, menus and other interactivity Page layout, html, css (color, fonts (but I have no artistic sense!)) The needs of the site and how it will work (planning) How can i judge how long it will take to complete a website? The site has CMS for adding and editing news, products, articles on the experience of the company. Also, they can edit team work, add Recreational Activities and a logo gallery with compressed psd download, and send messages to cpanel and to email. You are starting from scratch except JQuery and PHPmailer. How can I estimate how long the job will take, and how can I calculate the required time to finish any new projects? I'm so sorry for many scattered questions, but I'm in my first experiment and I want to take benefits from the great experience of those who have it.

• Gödel, Escher, Bach - Gödel's string

  - by Brad Urani

  In the book Gödel, Escher, Bach: An Eternal Golden Braid by Douglas Hofstadter, the author gives us a representation of the precursor to Gödel's string (Gödel's string's uncle) as: ~Ea,a': (I don't have the book in front of me but I think that's right). All that remains to get Gödel's string is to plug the Gödel number for this string into the free variable a''. What I don't understand is how to get the Gödel number for the functions PROOF-PAIR and ARITHMOQUINE. I understand how to write these functions in a programming language like FlooP (from the book) and could even write them myself in C# or Java, but the scheme that Hofstadter defines for Gödel numbering only applies to TNT (which is just his own syntax for natural number theory) and I don't see any way to write a procedure in TNT since it doesn't have any loops, variable assignments etc. Am I missing the point? Perhaps Gödel's string is not something that can actually be printed, but rather a theoretical string that need not actually be defined? I thought it would be neat to write a computer program that actually prints Gödel's string, or Gödel's string encoded by Gödel numbering (yes, I realize it would have a gazillion digits) but it seems like doing so requires some kind of procedural language and a Gödel numbering system for that procedural language that isn't included in the book. Of course once you had that, you could write a program that plugs random numbers into variable "a" and run procedure PROOF-PAIR on it to test for theoromhood of Gödel's string. If you let it run for a trillion years you might find a derivation that proves Gödel's string.

• Possible for one developer to work on a site thats on another developer's server?

  - by cire4

  Sorry for the confusing title. Let me explain: I am currently trying to get a site developed. My current developer has taken the site about as far as I think they are capable of and I am planning on hiring another developer to put the finishing touches on it, debug it and upgrade some of the more technical details. The site is hosted on my current developer's server. They are scheduled to work on it until mid-April, at which point they will transfer the site to my server. I would like the new developer to get started on the upgrades to the site as soon as possible. So my question is this: Is it possible for the new developer to start working on upgrades to the site while it is still on the old developer's server (and without the old developer knowing about it)? Would the new developer have to create a mirror site and work on it that way? I'm having trouble imagining if this is possible so any advice you can offer would be much appreciated!

• How to publicize new Android's HTTP requests library

  - by Yaniv

  I don't know if this really belongs here, but I developed an open-source HTTP requests library for Android called Unite. This library was built mainly to significantly facilitate the work and coding time, and makes it easy to create and work with HTTP requests. I think a big advantage of this library is that it is open-source, so everyone can contribute to make it even better. I started this project for personal use, and I really like the result. What is the right and proper way to publicize the project, I do think it will be handy to Android developers. So how can I make developers know this library exist?

• I need advice on laptop purchase for university [closed]

  - by Systemic33

  I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)

• Are there web frameworks/tools that optimize for speed of development?

  - by Ahmet Yildirim

  I've been a PHP web developer for about 2 and a half years now. I have started using CodeIgniter framework to shorten development process a while ago. I developed 4 websites using CodeIgniter. It has been really tiring and boring due to code-repetition. Code repetition was vast on form handling functions in controllers.So in my last project , i developed a general form input handling function.This lead a realisation that it could get even faster by more automation. What i think i lack in my development is using CRUD & Code Generation tools. But i am wondering if there is any other utilities that shortens development process. Which web development language or framework more inclined towards code generation utilities?

• Avoid GPL violation by moving library out of process

  - by Andrey

  Assume there is a library that is licensed under GPL. I want to use it is closed source project. I do following: Create small wrapper application around that GPL library that listens to socket, parse messages and call GPL library. Then returns results back. Release it's sources (to comply with GPL) Create client for this wrapper in my main application and don't release sources. I know that this adds huge overhead compared to static/dynamic linking, but I am interested in theoretical way.

• When to start thinking about scalability?

  - by Rits

  I'm having a funny but also terrible problem. I'm about to launch a new (iPhone) app. It's a turn-based multiplayer game running on my own custom backend. But I'm afraid to launch. For some reason, I think it might become something big and that its popularity will kill my poor lonely single server + MySQL database. On one hand I'm thinking that if it's growing, I'd better be prepared and have a scalable infrastructure already in place. On the other hand I just feel like getting it out into the world and see what happens. I often read stuff like "premature optimization is the root of all evil" or people saying that you should just build your killer game now, with the tools at hand, and worry about other stuff like scalability later. I'd love to hear some opinions on this from experts or people with experience with this. Thanks!
