  • Should we persist with an employee still writing bad code after many years?

    - by user94986
    I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

  • Error when updating enumerated value?

    - by igrad
    Once upon a time, there was a Player class (simplified version) enum animState{RUNNING,JUMPING,FALLING,IDLING}; class Player { public: Player(int x, int y); void handle(); void show(); ~Player(); private: int m_x; int m_y; animState playerAnimState; } There was also a "handle" function-member, which took care of all movement and collisions for the player: #include "player.h" void Player::handle() { if(/*Player presses 'D' key*/) { m_x++; playerAnimState = RUNNING; } //Other stuff that is just there to look nice Through lots of experimentation with "//" and "/**/", I've found that I consistently get an error at "playerAnimState = RUNNING." Have I broken some enumeration rule? Does my laptop really suck that bad? I hate to post a "fix my code for me" question, but I'm not very seasoned with enums.

  • Where would a senior PHP developer locate the method getActiveEntries()?

    - by darga33
    I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

  • Any patent issue if I want to call my classes "signal/slot" as in Qt?

    - by user129506
    I need to code a signal-like mechanism and I was thinking of using the same "slot" and "signal" terms to indicate the signal and the function that needs to be called. Since this is a commercial application I'd like to know if there might be any issue with using these names, e.g. if Qt has some sort of patent on them (I searched around but couldn't find it). I believe this is a stupid question since patenting a class name would be moronic, to say the least.. but anyway... To add some detail: my code is ENTIRELY different and has NOTHING TO DO with Qt except the above. I don't use moc or any Qt class.

  • How to make this design closer to proper DDD?

    - by Seralize
    I've read about DDD for days now and need help with this sample design. All the rules of DDD make me very confused to how I'm supposed to build anything at all when domain objects are not allowed to show methods to the application layer; where else to orchestrate behaviour? Repositories are not allowed to be injected into entities and entities themselves must thus work on state. Then an entity needs to know something else from the domain, but other entity objects are not allowed to be injected either? Some of these things makes sense to me but some don't. I've yet to find good examples of how to build a whole feature as every example is about Orders and Products, repeating the other examples over and over. I learn best by reading examples and have tried to build a feature using the information I've gained about DDD this far. I need your help to point out what I do wrong and how to fix it, most preferably with code as "I would not recomment doing X and Y" is very hard to understand in a context where everything is just vaguely defined already. If I can't inject an entity into another it would be easier to see how to do it properly. In my example there are users and moderators. A moderator can ban users, but with a business rule: only 3 per day. I did an attempt at setting up a class diagram to show the relationships (code below): interface iUser { public function getUserId(); public function getUsername(); } class User implements iUser { protected $_id; protected $_username; public function __construct(UserId $user_id, Username $username) { $this->_id = $user_id; $this->_username = $username; } public function getUserId() { return $this->_id; } public function getUsername() { return $this->_username; } } class Moderator extends User { protected $_ban_count; protected $_last_ban_date; public function __construct(UserBanCount $ban_count, SimpleDate $last_ban_date) { $this->_ban_count = $ban_count; $this->_last_ban_date = $last_ban_date; } public function banUser(iUser &$user, iBannedUser &$banned_user) { if (! $this->_isAllowedToBan()) { throw new DomainException('You are not allowed to ban more users today.'); } if (date('d.m.Y') != $this->_last_ban_date->getValue()) { $this->_ban_count = 0; } $this->_ban_count++; $date_banned = date('d.m.Y'); $expiration_date = date('d.m.Y', strtotime('+1 week')); $banned_user->add($user->getUserId(), new SimpleDate($date_banned), new SimpleDate($expiration_date)); } protected function _isAllowedToBan() { if ($this->_ban_count >= 3 AND date('d.m.Y') == $this->_last_ban_date->getValue()) { return false; } return true; } } interface iBannedUser { public function add(UserId $user_id, SimpleDate $date_banned, SimpleDate $expiration_date); public function remove(); } class BannedUser implements iBannedUser { protected $_user_id; protected $_date_banned; protected $_expiration_date; public function __construct(UserId $user_id, SimpleDate $date_banned, SimpleDate $expiration_date) { $this->_user_id = $user_id; $this->_date_banned = $date_banned; $this->_expiration_date = $expiration_date; } public function add(UserId $user_id, SimpleDate $date_banned, SimpleDate $expiration_date) { $this->_user_id = $user_id; $this->_date_banned = $date_banned; $this->_expiration_date = $expiration_date; } public function remove() { $this->_user_id = ''; $this->_date_banned = ''; $this->_expiration_date = ''; } } // Gathers objects $user_repo = new UserRepository(); $evil_user = $user_repo->findById(123); $moderator_repo = new ModeratorRepository(); $moderator = $moderator_repo->findById(1337); $banned_user_factory = new BannedUserFactory(); $banned_user = $banned_user_factory->build(); // Performs ban $moderator->banUser($evil_user, $banned_user); // Saves objects to database $user_repo->store($evil_user); $moderator_repo->store($moderator); $banned_user_repo = new BannedUserRepository(); $banned_user_repo->store($banned_user); Should the User entitity have a 'is_banned' field which can be checked with $user->isBanned();? How to remove a ban? I have no idea.

  • Css clicking problem [migrated]

    - by Shyghar
    I'm building a strange div shaped structure and I need a hint to resolve a clicking problem. This is a jsfiddle to show you the issue. The structure for each element is: <div class="views-row"> <div class="diamonds-container"> CONTENT </div> </div> I have a onclick() event on .diamonds-container but the .views-row div of the next element [with red or blue background..] go over the container and stop the click event on it. I tryed to play with the z-index but I didn't have the expected result. How can I achieve this structure with a correct click event on diamonds-containers ? I think I can track the .views-row click with javascript and trigger manually a click on the previous diamonds-container but this will be my final option. How can I achieve this without javascript?

  • Do ALL your variables need to be declared private?

    - by shovonr
    I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly loose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

  • What happens if we serialize and deserialize two objects which references to each other?

    - by Seregwethrin
    To make it more clear, this is a quick example: class A implements Serializable { public B b; } class B implements Serializable { public A a; } A a = new A(); B b = new B(); a.b = b; b.a = a; So what happens if we serialize a and b objects into a file and deserialize from that file? I thought we get 4 objects, 2 of each. Identical objects but different instances. But I'm not sure if there's anything else or is it right or wrong. If any technology needed to answer, please think based on Java. Thank you.

  • What does ^+Z do to a process

    - by Kifsif
    In command line I wrote: michael@ubuntu:~$ firefox Firefox launched. Command prompt ($) disappeared. Then I pressed ^+z. The result was: [1]+ Stopped firefox Well, Firefox really stopped. It did not react anyhow. So, I could not close it by pressing the cross of the window. By the way, the menu items 'Tools', and 'Help' somehow showed some signs of life. They showed drop-down lists, but nothing more (no reaction to inner menu items). Well, I could not end Firefox through System Monitor. Could you comment on this case: what happened after pressing ^+z?

  • Blank lines between sourcecode [closed]

    - by manix
    I'm so confused with a strange behaviour. Actually I have edited some php files remotely with my PhpDesigner8 (a php editor). Everything goes right, but when my teammates reopen the files that I have edited the source code have blank lines like below: class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Instead of class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Did you have experience these kinds of problems?

  • Multiple parameters vs single parameter(object with multiple properties)

    - by Shwetanka
    I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

  • Color based collision detection

    - by user1486826
    I am making a game where you fly a ship around some randomly generated planets. Since I am using a for loop to draw over 5000 planets, using the rectangle class or an oval-type class for this is not an option, since creating many objects will severely affect performance. Bitmasking each planet will likely result in performance issues too, so the only candidate is color based collision detection, because I don't need to apply some sort of object to everything I want to check for collisions. Is any way to check the perimeter around the ship for a certain color?

  • Using <strong> for introductory paragraph to a post - a bad idea?

    - by user1515699
    I have a news website and on most posts the first paragraph is in bold. Currently the authors are just using <strong> to bold the paragraph, would it be better from an SEO point of view to rather use a paragraph class that is styled with p.bold {font-weight:bold;} <p class="bold">. Does <strong> on the first paragraph send the wrong message to search engines? The text is important but the main reason it is in bold is because it is the opening paragraph. I realise <strong> is used to emphasise certain words on a page

  • How to prevent a search engines from indexing a section of a page?

    - by BrunoLM
    I have many pages with lots of text in it. But I will always have two sections of text and I want to prevent one section from appearing in search results, the other section must be indexed. <p class="please-index-me">text</p> <p class="get-out">never index me please</p> I thought that maybe if I load the "please don't index me text" with Javascript maybe search engines wouldn't look for it. But I am not sure it would work and this is not really nice. I was wondering if there is a way to tell search engines "hey, this text you can't grab, move on". So, is there a way to do it?

  • Repainting a window with a new scene with winapi (beginner question)

    - by user90760
    I'm following theForger's win32 API tutorial in order to create a GUI for a project. I've successfully made simple, one window applications, but I can't figure out how to repaint an entire window with new information. As an example: I have five buttons corresponding to five colors on the main application window. When a user clicks a color button, the entire window is repainted such that: 1. all five buttons are removed and a new "back" button is replaced, 2. the background is colored the color that was picked. I'm able to change the background color by trapping the button pressed message in my wndproc, but I can't figure out how to change the entire window with a new "scene" (removing the color buttons and adding a back button). This seems like a trivial task, but I can't find a solution in tutorials. Do I need to declare a new windows class with the back button and then have my button trap create a window of this class?
