    I have a new site just over 6 months old and after a month or so, it started ranking for some searches in Google.

  • calculating player experience

    - by user1765862
    very simple question, I'm trying to learn advanced principles of .net and c# and I'm in the middle of creating some simple manager game. Now I should implement some experience for players. I was thinking to implement some kind of enumerated values like this private enum ExperienceValues { FriendlyMatch = 0.1, Training = 0.15, LeagueMatch = 0.6, CupMatch = 0.85, Qualification = 1.4 } And to calculate experience by the time user spend on the field 90min * 0.6 = 54 Is this approach ok ? How can I abstract experience calculation for common sports (team sport). Thanks

  • SEO Mistakes to Be Avoided!

    As a beginner in search engine optimization, it is easy to make some of the most common mistakes people make. In short, search engines are designed to respond only to the websites and its pages, not to your lack of experience in creating them. This often leads to individuals who have the willingness to do really well and have all the right intentions but seem to be lacking in the actual ability to put together an effective website.

  • Win32 scrolling examples

    - by Christopher
    Could anyone point me to (or provide?) some nice, clear examples of how to implement scrolling in Win32? Google brings up a lot of stuff, obviously, but most examples seem either too simple or too complicated for me to be sure that they demonstrate the right way of doing things. I use LispWorks CAPI (cross-platform Common Lisp GUI lib) in my current project, and on Windows I have a hard-to-figure-out bug relating to scrolling; basically I want to do some tests directly via the Win32 API to see if I can shed some light on the situation. Many thanks, Christopher

  • Books about the philosophy of software development

    - by anon
    The first time I read The Mythical Man Month, I found the book utterly boring, a waste of my time, and thought it was written by some management guru that never wrote a line of code. A few years later, I realized Fred Brooks won the Turing award. Some years after that, after a few large development projects, I started understanding what he was talking about. Are there any other books about software development on a meta/philosophical level—not in the sense of design patterns, templates, or even lisp macros—but at a level where ideas are expressed without code?

  • Emacs - Error when calling (server-start)

    - by Jonas Gorauskas
    I am currently using GNU Emacs 23.0.93.1 in Windows Vista SP1. In my .emacs file I make a call to (server-start) and that is causing an error with the message The directory ~/.emacs.d/server is unsafe. Has anyone seen this and know a fix or workaround? ... other than leaving server turned off ;) Here is the stack trace: Debugger entered--Lisp error: (error "The directory ~/.emacs.d/server is unsafe") signal(error ("The directory ~/.emacs.d/server is unsafe")) error("The directory %s is unsafe" "~/.emacs.d/server") server-ensure-safe-dir("~\\.emacs.d\\server\\") server-start(nil) call-interactively(server-start t nil) execute-extended-command(nil) call-interactively(execute-extended-command nil nil)

  • Nginx A/B testing

    - by Alex
    Hey, I'm trying to do A/B testing and I'm using Nginx fo this purpose. My Nginx config file looks like this: events { worker_connections 1024; } error_log /usr/local/experiments/apps/reddit_test/error.log notice; http { rewrite_log on; server { listen 8081; access_log /usr/local/experiments/apps/reddit_test/access.log combined; location / { if ($remote_addr ~ "[02468]$") { rewrite ^(.+)$ /experiment$1 last; } rewrite ^(.+)$ /main$1 last; } location /main { internal; proxy_pass http://www.reddit.com/r/lisp; } location /experiment { internal; proxy_pass http://www.reddit.com/r/haskell; } } } This is kind of working, but css and js files woon't load. Can anyone tell me what's wrong with this config file or what would be the right way to do it? Thanks, Alex

  • Dynamically evaluating simple boolean logic in Python

    - by a paid nerd
    I've got some dynamically-generated boolean logic expressions, like: (A or B) and (C or D) A or (A and B) A empty - evaluates to True The placeholders get replaced with booleans. Should I, Convert this information to a Python expression like True or (True or False) and eval it? Create a binary tree where a node is either a bool or Conjunction/Disjunction object and recursively evaluate it? Convert it into nested S-expressions and use a Lisp parser? Something else? Suggestions welcome.

  • Decision Tree code golf

    In Google Code Jam 2009, Round 1B, there is a problem called Decision Tree that lent itself to rather creative solutions.

  • How to implement lambda as a function called "lambda" in Clojure?

    - by dirtyvagabond
    I'd like to be able to define lambdas using common Lisp syntax, in Clojure. For example: (lambda (myarg) (some-functions-that-refer-to myarg)) This needs to result in the same as: #(some-functions-that-refer-to %) In my case, I know I'll always have exactly one arg, so perhaps that simplifies things. (But it can be called anything -- "myarg" or whatever.) I suspect a workable solution is to "(defmacro lambda ...". If so, I'm not sure of the best way to proceed. How to cleanly translate the arg name to %? And how to end up with the correct function? Or, is there a simpler solution than writing my own macro that actually re-implements Clojure's... lambda?

  • How prevalent is the use of Emacs' eshell in multi-platform development?

    - by pajato0
    I've only recently become aware of Emacs' eshell tool. It looks quite powerful in that it is entirely written in Emacs Lisp and does not require native subshell support. The Emacs info documentation is a bit sparse but EmacsWiki has pretty decent information, at least on a first glance. Given the potential value of eshell as a scripting tool/programmer's aid that works equally well on multiple platforms I'm wondering how prevalent the use of eshell versus the normal (bash) shell is among software developers. Would those of you who have taken the time to learn it recommend it or is it one of those many interesting ideas that did not really pan out?
