  • How do you avoid being a "blowhard"?

    - by Conrad Frix
    When I'm passionate about something (particularly programming) I find it really easy come off like the guy Peter G. was talking about in Dealing with the “programming blowhard”. So what techniques do you use to 1) Identify when you are indeed a blowhard? 2) Communicate something "important" without seeming self important? Specific example help like When giving criticism ask "have you considered what happens when XXX changes" instead of "never take dependencies on implementation details" When giving advice "showing with code is better than talking" or use a reference.

  • How does a web browser save passwords?

    - by marcus
    How do current web browsers (or mobile mail clients and any software in general) save user passwords? All answers about storing passwords say we should store only hashes, not the password themselves. But I'm having a hard time searching the web trying to find the best techniques to store passwords when we know we will need them in plain text later on — without storing them in plain text, without using a weak encryption (known key) and without asking the user for a master password. Any ideas?

  • Selectively Exposing Functionallity in .Net

    - by David V. Corbin
    Any developer should be aware of the principles of encapsulation, cross-tier isolation, and cross-functional separation of concerns. However, it seems the few take the time to consider the adage of "minimal yet complete"1 when developing the software. Consider the exposure of "business objects" to the user interface. Some common situations occur: Accessing a given element requires a compound set of calls that do not "make sense" to the User Interface. More information than absolutely required is exposed to the user interface It would be much cleaner if a custom interface was provided that exposed exactly (and only) the information that is required by the consumer. Achieving this using conventional techniques would require the creation (and maintenance!) of custom classes to filter and transpose the information into the ideal format. Determining the ROI on this approach can be very difficult to ascertain, and as a result it is often ignored completely. There is another approach, which is largely made practical by virtual of the Action and Func delegates. From a callers point of view, the following two samples can be used interchangeably:     interface ISomeInterface     {         void SampleMethod1(string param);         string SamepleMethod2(string param);     }       class ISomeInterface     {         public Action<string> SampleMethod1 {get; }         public Func<string,string> SamepleMethod2 {get; }     }   The capabilities this simple changes enable are significant (and remember it does not cange the syntax at the call site): The delegates can be initialized to directly call the proper method of any target class. The delegates can be dynamically updated based on the current state. The "interface" can NOT be cast to the concrete class (which often exposes more functionallity). This patterns By limiting the interface to the exact functionallity required, the reduced surface area will typically result in lower development, testing and maintenance costs. We are currently in the process of posting a project on CodePlex which illustrates this (and many other) techniques which have proven helpful in creating robust yet flexible solutions that are highly efficient2 and maintainable. This post will be updated as soon as the project is published. 1) Credit: Scott  Meyers, Effective C++, Addison-Wesley 1992 2) For those who read my previous post on performance it should be noted that the use of delegates is on the same order of magnitude (actually a tiny amount faster) as conventional interfaces.

  • Dealing with state problems in functional programming

    - by Andrew Martin
    I've learned how to program primarily from an OOP standpoint (like most of us, I'm sure), but I've spent a lot of time trying to learn how to solve problems the functional way. I have a good grasp on how to solve calculational problems with FP, but when it comes to more complicated problems I always find myself reverting to needing mutable objects. For example, if I'm writing a particle simulator, I will want particle "objects" with a mutable position to update. How are inherently "stateful" problems typically solved using functional programming techniques?

  • Preferred way to render text in OpenGL

    - by dukeofgaming
    Hi, I'm about tu pick up computer graphics once again for an university project. For a previous project I used a library called ftgl that didn't leave me quite satisfied as it felt kind of heavy (I tried all rendering techniques, text rendering didn't scale very well). My question is, is there a good and efficient library for this?, if not, what would be the way to implement fast but nice looking text?. Some intended uses are: Floating object/character labels Dialogues Menus HUD Regards and thanks in advance. EDIT: Preferrably that it can load fonts

  • Guiding Management to the Correct Decision

    - by Blumer
    My supervisor (also a developer) and I have a running joke about writing a book called "Managing From Beneath: Subversively Guiding Management to the Right Decision" and including a number of "techniques" we've developed for helping those who make the decisions to make the right ones. So far, we've got (cynicism warning!): BIC It! BIC stands for "Bury In Committee." When a bad idea comes up that someone wants to champion, we try to get it deferred to a committee for input. Typically it will either get killed outright (especially if other members of the committee are competing for you as a resource), or it will be hung up long enough that the proponent forgets about it. Smart, Stupid, or Expensive? When someone gets a visionary idea, offer them three ways to do it: a smart way, a stupid way, and an expensive way. The hope is that you've at least got a 2/3 shot of not having to do it the way that makes a piece of your soul die. All-Pro. It's a preemptive pro/con list in which you get into the mind of the (pr)opponent and think what would be cons against doing it your way. Twist them into pros and present them in your pro list before they have a chance to present them as cons. Dependicitis. Link pending decisions together, ideally with the proponent's pet project as the final link in the chain. Use this leverage to force action on those that have been put off. Preemptive Acceptance. Sometimes it's clear that management is going to go a particular direction regardless of advice to the contrary, and it's time to make the best of it. Take the opportunity to get something else you need, though. Approach the sponsor out of the blue and take the first step: "You know, I've been thinking about it, and while it's not the route I would advise, as long as we can get the schedule and budget for Project Awesome loosened up, I can work some magic to make your project fly." So ... what techniques have you come up with to try to head off the problem projects or make the best of what may come?
