• "PHP: Good Parts"-ish book / reference

  - by julkiewicz

  Before I had my first proper contact with Javascript I read an excellent book "Javascript: The Good Parts" by Douglas Crockford. I was hoping for something similar in case of PHP. My first thought was this book: "PHP: The Good Parts" from O'Reilly However after I read the reviews it seems it totally misses the point. I am looking for a resource that would: concentrate on known shortcommings of PHP, give concrete examples, be as exhaustive as possible I already see that things can go wrong. If you want to close this question: Please consider this, I looked through SO, and Programmers for materials. I obviously found this question: http://stackoverflow.com/questions/90924/what-is-the-best-php-programming-book It's general, mine is specific. Moreover I'm reading the top recommendation "PHP Objects, Patterns, and Practice" right now. I find it insufficient -- it doesn't address the bad practices as much as I would like it to. tl;dr My question is NOT a general PHP book request.

• Powershell Active Directory Account Attribute to a variable

  - by Bill Garrett

  Sorry for the newbie question. I am using Powershell 3 to get a list of all user accounts. I am trying to generate an output for accounts, either "Enabled" or "Disabled". I am able to get the account status code from active directory using: $rc = $Rech.PropertiesToLoad.Add("userAccountControl"); That will display the correct account status code. When I try to use an if statement on the value, I dont get any result. How do I put this value into a variable to use some logic with it? In the end, my requirements are to have the output to an CSV file that I can send to HR and have them examin it and instead of a code I would like to have it say "Enabled" or "Disabled". Thank you.

• Is it a bad practice to register sntsh.com if my name is Santosh?

  - by Santosh

  My name is Santosh but I can't register a santosh.com because it is already taken. Most extensions for Santosh are already taken. I was trying to register a domain with .sh extension but santo.sh would cost me very high and I can't afford ~$100 for just a personal domain and that's only for one year only. Now I am thinking that I should register a sntsh.com. But there is a problem, will sntsh.com over my name Santosh don't create a SEO problem? One more thing, that totally different from above topic. If I register a santosh.name domain which is not registered, won't it create copyright and any legal problems with other santosh domains?

• Investigating a big C++ project from its source code [closed]

  - by user827992

  Possible Duplicate: What is the best method to start understanding BIG project source code? I have a project that I would like to dissect to learn something new from it. This project is about 200 megabytes. For me, it is just impossible to open every cpp and hpp file and read each and every one. I also don't know what is the best approach in this case. Many people on the internet are looking for an UML tool to generate some kind of graph. I think that UML works well when you are starting a project and you want to express the business logic of your classes and methods. In my opinion UML is totally useless when studying a project only from its source code. Also UML is an OO language, in a large sized C++ project I find a lot of stuff that is not an object and can express some other kind of paradigm. Can you name a tool or a class of software that can help with this?

• Website Stopped Showing From Google Search Results Sunddenly

  - by Aman Virk

  I have a design and development blog http://www.thetutlage.com (1.5 years old), which was doing really well in Google search as I was getting over 70% of my traffic from Google. Now suddenly from last two days it reduced the amount of traffic from 70% to 20% and also when I am trying to search for the exact posts that I can created even after appending my website name to it does not show any results for that. Sample Search Text: JQuery Game Programming Creating A Ping Pong Game Part 1 I have post with exact same title and it does not show it on Google search anywhere. I am totally shocked, I write my own unique content and follow Google guide lines like bible. Also there is no message under my webmasters account stating any problem or error.

• How many developers actually have private offices?

  - by Prof Plum

  So I know everyone here is all about private offices, how many developers actually have them. I am sort of half skeptical. I can believe that lead developers have them, but thats normally just one person in your average office. If it would not be to much to ask: Do you work in a totally awesome office or a nasty old cube? (or somewhere in between) What's your relative rank in the office? (junior, programmer II, senior, lead, etc.) are you doing internal software, or are you in a software-centric environment? (the general thought seems to be that internal developers get cubes while others live in "Joel-Spolsky-Programmer-Candyland")

• Android Loading Screen: How do I use a stack to load elements?

  - by tom_mai78101

  I have some problems with figuring out what value I should put in the function: int value_needed_to_figure_out = X; ProgressBar.incrementProgressBy(value_needed_to_figure_out); I've been researching about loading screens and how to use them. Some examples I've seen have implemented Thread.sleep() in a Handler.post(new Runnable()) function. To me, I got most of that concept of using the Handler to update the ProgressBar, while pretending to do some heavy crunching work. So, I kept looking. I have read this thread here: How do I load chunks of data from an assest manager during a loading screen? It said that I can try using a stack it needs to load, and adding a size counter as I add elements to the stack. What does it mean? This is the part where I'm totally stumped. If anyone would provide some hints, I'll gladly appreciate it. Thanks in advance.

• How to link subprograms to a main program's game loop?

  - by Jim

  I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is roughly : how does it work ? It seems that each robot's code is compiled by the main program and then used in a way I cannot understand. I thought it could yields a thread for each robot, but I have not any proof of this and it seems a bit complicated to achieve it. Any idea how it could work, someone ?

• GLIBC_2.8 not found

  - by Thomas Nilsson

  As a newbie I seem to have messed up my upgrade leaving my system in a very unstable state. I attempted an upgrade from 8.04LTS which ended in an error about libc and kernel upgrades. I tried to upgrade the kernel but am now unsure if that worked, because when I retried my dist-upgrade there was a lot of errors about pre-dependencies and leaving packages un-configured. Now I have a system that answers almost every command with: /lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) I probably should try a complete re-installation, but I'm investigating if there is any possibility of getting a working glibc so that I at least can have some commands working to ensure that my backups are recent etc. before doing the clean install. not even 'ls' works without saying "glibc_2.8 not found".

• How to run applications as root?

  - by ????? ????????

  I am having some strange issue with Kate and Kwrite. When I click on Open File, it crashes with segmentation fault. I am a complete newbie to Linux, and I think the issue is that I am not running the application as root. How do I run applications as root in Ubuntu? Is it bad practice to do this? What is the purpose of the whole root thing, where even though we need to use root so frequently, it is not utilized as default?

• Are flag variables an absolute evil?

  - by dukeofgaming

  I remember doing a couple of projects where I totally neglected using flags and ended up with better architecture/code; however, it is a common practice in other projects I work at, and when code grows and flags are added, IMHO code-spaghetti also grows. Would you say there are any cases where using flags is a good practice or even necessary?, or would you agree that using flags in code are... red flags and should be avoided/refactored; me, I just get by with doing functions/methods that check for states in real time instead. Edit: Not talking about compiler flags

• Is the wireless driver from Live USB different from the standard install?

  - by Rafael Magalhães

  Linux newbie here. I've been trying to use Ubuntu (x64) as my main OS since 11.10, but my wireless connection on it has been very unstable, droping every other 5-10 mins. For this reason I see myself forced to use Windows 7 (dual booting), where connection works flawlessly -- which really bothers me. My card is an Atheros 9k, which claims a reasonable amount of wireless complaints on Ubuntu forums. I've tried every suggestion given on past questions to this site but to no avail. However, while running Ubuntu Live USB for some of the tests, I noticed that my wireless connection never failed on it and wondered if its network configuration differs from the one on the default Ubuntu install. If this is the case, how could I reproduce the Live USB network environment on my hard drive install?

• Can an app in opt/extras install themeable icons in /usr/share

  - by Peter Levi

  My application Variety Wallpaper Changer runs from /opt/extras and uses an indicator icon. I would like to make this indicator icon theme-specific. As far as I understand the standard way is to install named icons into /usr/share/icons with xdg-icon-resource at installation time (Am I right about this?). I have two questions regarding this: Variety installs and runs from /opt/extras.ubuntu.com. Is it acceptable for it to install icons in /usr/share using xdg-icon-resource or is there something else I can do to have theme-specific icons without special-casing themes and dynamically selecting the icon in the code? Variety is packaged using Quickly (and I'm myself a newbie at packaging) - how can I configure it to install theme-specific named icons at installation time?

• Understanding Data Binding for Windows Phone 7

  - by nikhil

  I want to develop a simple app for the Windows Phone 7 platform. It's basically a vocabulary based game that involves the user moving word tiles from one area to another to score points. I want to know what is the best way of tying the UI to the game's backend? I saw the Windows Phone 7 jumpstart videos, there they touch up on Data Binding but don't really go into any depth. I'm a newbie and don't have any experience with designing the architecture for a phone app, It'd be great if someone could explain what steps I should be taking or guide me to a resource from where I could learn more.

• What is the best way to find a python google app engine coach?

  - by David Haddad

  i'm a software engineer and have been building Google App Engine apps with Python for about a year. I have a pretty good familiarity with the main concepts: web app framework, modeling, queues, memcache, django templates, etc. Where I think I'm lacking is in methodology. Architecting the app, using git for versioning, designing an writing unit tests. I'm totally convinced to incorporate these practices in my development style, and have started reading up on them. However I've learned that I'm a much faster learner when I have someone experienced to ask questions to and interact with. IRC channels and forums like stack overflow are great. But sometimes you want something more dynamic that produces results faster. So my question is how can a person find an experienced engineer that is familiar with the technologies he uses and that is willing to give them a couple of hours of Skype coaching sessions per week in return for an hourly fee...

• ubuntu 12.04 refuses to install with windows 7

  - by Amitabh Pandey

  I have a desktop computer with windows 7 installed on it . Recently I downloaded ubuntu 12.04 and burned the iso image on a new blank DVD . After successfully burning DVD , I booted from the DVD. Ubutu interface appeared asking me to either choose try ubuntu or install ubuntu . I chose to install ubuntu. Again on next screen I choose to install ubuntu inside windows 7. After pressing continue button the following message appeared : " checking battery state .............. ok checking for running unattended upgrades : acpid : exiting speech dispatcher disabled ; edit /etc/default/ speech -dispatcher Asking all remaining processes to terminate ............. ok Please remove installation media and close the tray (if any) then press enter : " Now the problem is that when I remove the installation media ( ie the DVD ) and press enter then instead of installing ubuntu the computer reboots into windows 7 !!! I am a newbie to ubuntu and therefore do not know much about it . What should I do?

• Pattern for performing game actions

  - by Arkiliknam

  Is there a generally accepted pattern for performing various actions within a game? A way a player can perform actions and also that an AI might perform actions, such as move, attack, self-destruct, etc. I currently have an abstract BaseAction which uses .NET generics to specify the different objects that get returned by the various actions. This is all implemented in a pattern similar to the Command, where each action is responsible for itself and does all that it needs. My reasoning for being abstract is so that I may have a single ActionHandler, and AI can just queue up different action implementing the baseAction. And the reason it is generic is so that the different actions can return result information relevant to the action (as different actions can have totally different outcomes in the game), along with some common beforeAction and afterAction implementations. So... is there a more accepted way of doing this, or does this sound alright?

• What is the simplest human readable configuration file format?

  - by Juha

  Current configuration file is as follows: mainwindow.title = 'test' mainwindow.position.x = 100 mainwindow.position.y = 200 mainwindow.button.label = 'apply' mainwindow.button.size.x = 100 mainwindow.button.size.y = 30 logger.datarate = 100 logger.enable = True logger.filename = './test.log' This is read with python to a nested dictionary: { 'mainwindow':{ 'button':{ 'label': {'value':'apply'}, ... }, 'logger':{ datarate: {'value': 100}, enable: {'value': True}, filename: {'value': './test.log'} }, ... } Is there a better way of doing this? The idea is to get XML type of behavior and avoid XML as long as possible. The end user is assumed almost totally computer illiterate and basically uses notepad and copy-paste. Thus the python standard "header + variables" type is considered too difficult. The dummy user edits the config file, able programmers handle the dictionaries. Nested dictionary is chosen for easy splitting (logger does not need or even cannot have/edit mainwindow parameters).

• Inspecting the model in a Rails application

  - by Matt Sherman

  I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?
