• Web Hosting Checklist

  - by Chris

  Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

• Stacks in C++

  - by MarkPearl

  So some more basics… One of the things you will be taught at any college after conquering arrays is different derivatives of collections. Stack is one of the simplest of those and very useful… A stack is a LIFO (last in first out) data structure and has at least two basic method calls – push & pop. Push, “pushes” an item on the top of the stack. Pop, removes the top most item off the stack. Because all elements on a stack are of the same type, one can use an array to implement a stack or a linked list. With the array based approach, the first element in a stack would be the first element in the array, the second on the stack would be the second on the array, etc. One limitation with an array implementation of a stack is that unless the array is dynamic, one would have to have a preset max stack size (based on the bounds of the array). Linked lists is another approach that gets past this boundary by allowing you to dynamically grow or shrink a collection of data. Stacks have many applications… a typical computer science example would be Postfix Expression Calculator, where the LIFO principle is maintained.

• Find meeting point of 2 objects in 2D, knowing (constant) speed and slope

  - by Axonn

  I have a gun which fires a projectile which has to hit an enemy. The problem is that the gun has to be automatic, i.e. - choose the angle in which it has to shoot so that the projectile hits the enemy dead in the center. It's been a looooong time since school, and my physics skills are a bit rusty, but they're there. I've been thinking to somehow apply the v = d/t formula to find the time needed for the projectile or enemy to reach a certain point. But the problem is that I can't find the common point for both the projectile and enemy. Yes, I can find a certain point for the projectile, and another for the enemy, but I would need lots of tries to find where the point coincides, which is stupid. There has to be a way to link them together but I can't figure it out. I prepared some drawings and samples: A simple version of my Flash game, dumbed down to the basics, just some shapes: http://axonnsd.org/W/P001/MathSandBox.swf - click the mouse anywhere to fire a projectile. Or, here is an image which describes my problem: So... who has any ideas about how to find x3/y3 - thus leading me to find the angle in which the weapon has to tilt in order to fire a projectile to meet the enemy? EDIT I think it would be clearer if I also mention that I know: the speed of both Enemy and Projectile and the Enemy travels on a straight vertical line.

• Beginning with shell scripting

  - by Kevin Wyman

  I am fresh into Ubuntu and one of my goals is shell scripting for personal (and maybe public) use. I'm a novice, though I do understand some of the basics (e.g. what a variable, string, loop, etc... is) but to get the most of scripting I need to learn in-depth. I figure the best way to do that is to jump right into scripting and ask questions only pertinent to the stage I am at in my attempted script. Scenario: I have edited my sudoers file to allow my non-root user to run sudo commands without being prompted for a password. Question: In vim, what would be the best code to use for a function that checks whether this condition is [true], If not, prompt the user if they want the script to edit and save the sudoers file to make this condition [true]? Layout - If condition is true, carry-on with rest of script. If condition is not true, the script silently edits/adds the line: %sudo ALL=(ALL:ALL) NOPASSWD: ALL in the sudoers file, saves and then continues on with the next part of the script. Any help with this would be greatly appreciated and assist me in my journey to writing shell scripts.

• First Installation

  - by Dj Zia

  I had windows xp on my desktop originally. Yesterday we were able to replace this with Ubuntu 12.04 from a thumb drive. The live CD did not work. I am more familiar with the system they introduced me to in School recently. Linux pretty much has similarity all around so I am finding the differences not as much of an issue. So, there were a few issues with the installation and getting Grub to start working. There is the low graphics issue which brings us to the command line basics. I am a little familiar with linux so it isn't too intimidating; I am really good with step by step instructions in simple order. My question is Ubuntu installed with out any basic driver's or generic header's. It also is not connecting my computer to the internet. My system is older not new. For the time it had above average parts. How do I solve the problem of Getting the header's, making sure the right configurations are set, and where do I get the driver's for my white box desktop to run Ubuntu properly? Thank you

• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• where to start and lack of motivation

  - by anoguy

  I have a few questions that have been bothering me for quite a while, maybe you guys can give me some tips. So let me give a very brief explanation about what I am doing at the moment (like someone cares lol). At the moment I am a last year student on computer science. And like most of you already know is that you won't learn deep programming there, you need to learn it yourself. So at the moment I know like the basics of c++, java, html, php. But it's all bits of this and bits of that. I seriously want to dive deeper in the programming world but there are so many programming languages on the web and there is so much information that i don't know where to start any more.. And that's not the biggest issue, I also lost a bit of my motivation for programming and I like to get more motivation for it so that I love what I do (I am also a very lazy person btw, that's also a problem playing here). So can you guys give me some tips for helping me, because I really want to get pumped up and make cool stuff. (sry for my bad english XD)

• Advice on developing a social network [on hold]

  - by Siraj Mansour

  I am doing research on assembling a team, using the right tools, and the cost to develop a highly responsive social network that is capable of dealing with a lot of users. Similar to the Facebook concept but using the basics package for now. Profile, friends, posts, updates, media upload/download, streaming, chat and Inbox messaging are all in the package. We certainly do not expect it to be as popular as Facebook or handle the same number of users and requests, but in its own game it has to be a monster, and expandable for later on. Neglecting the hosting, and servers part, i am looking for technical advise and opinions, on what kind of team i need ? how many developers ? their expertise ? What are the right tools ? languages ? frameworks ? environments ? Any random ideas about the infrastructure ? Quick thoughts on the development process ? Please use references, if you have any to support your ideas. Development cost mere estimation ? NEGLECTING THE COST OF SERVERS I know my question is too broad but my knowledge is very limited and i need detailed help, for any help you can offer i thank you in advance.

• Advanced PHP book [closed]

  - by Aaditi Sharma

  I've gone and stumbled across a lot of recommendations for PHP books, including on SO, however could not find a reasonable & convincible answer for this. Is there a really good advanced book for PHP. Background: I've done almost 8 months in PHP. I know the basics. I go through php.net very often. I've played around with Codeigniter, amongst other frameworks. I've been doing JavaScript for almost 2 years, and specifically thank Douglas Crockford for this, I completely changed the way I code JavaScript. I spend a lot of time travelling, and would love to read a book about PHP, that includes the awesome parts and even when something doesn't quite work in PHP. (As a note a lot of previous answers on SO and programmers give varied results.) I have to place an order through a library which has it's limitations. One book that some of experienced PHP programmers could recommend would be helpful. I have gone through http://stackoverflow.com/questions/1711/what-is-the-single-most-influential-book-every-programmer-should-read and http://stackoverflow.com/questions/194812/list-of-freely-available-programming-books, which do NOT have books related to PHP.

• Deferred rendering order?

  - by Nick Wiggill

  There are some effects for which I must do multi-pass rendering. I've got the basics set up (FBO rendering etc.), but I'm trying to get my head around the most suitable setup. Here's what I'm thinking... The framebuffer objects: FBO 1 has a color attachment and a depth attachment. FBO 2 has a color attachment. The render passes: Render g-buffer: normals and depth (used by outline & DoF blur shaders); output to FBO no. 1. Render solid geometry, bold outlines (as in toon shader), and fog; output to FBO no. 2. (can all render via a single fragment shader -- I think.) (optional) DoF blur the scene; output to the default frame buffer OR ELSE render FBO2 directly to default frame buffer. (optional) Mesh wireframes; composite over what's already in the default framebuffer. Does this order seem viable? Any obvious mistakes?

• NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

  - by Big Daddy

  Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

• Deciding on a company-wide javascript strategy [on hold]

  - by drogon

  Our company is moving most of its software from thick-client winforms apps to web apps. We are using asp.net mvc on the server side. Most of the developers are brand new to the web and need to become efficient and knowledgeable at writing client-side web code (javascript). We are deciding on a number of things and would appreciate feedback on the following: Angular.js or Backbone.js? Backbone (w/ Underscore) is certainly more light weight, but requires more custom development. Angular seems to be a full-fledged framework, but would require everyone to embrace it and probably a longer learning curve(??). (Note: I know nothing about Angular at this point) Require.js or script includes w/ MVC bundleconfig? Require.js makes development "feel like" c# (importing namespaces). But, integrating the build/minification process can be a pain (especially the configuration). Bundling via mvc requires developers to worry more about which scripts to include but has less overall development friction. Typescript vs Javascript Regardless of frameworks, our developers are going to need to learn the basics. Typescript is more like c# and MAY be easier for c# developers to understand. However, learning TypeScript before javascript may hinder their mastery of javascript at the expense of efficiency.

• The Start of a Blog

  - by dbradley

  So, here's my new blog up and running, who am I and what am I planning to write here?First off - here's a little about me:I'm a recent graduate from university (coming up to a year ago since I finished) studying Software Engineering on a four year course where the third year was an industrial placement. During the industrial placement I went to work for a company called Adfero in a "Technical Consultant" role as well as a junior "Information Systems Developer". Once I completed my placement I went back to complete my final year but also continued in my developer role 2/3 days a week with the company.Working part time while at uni always seems like a great idea until you get half way through the year. For me the problem was not so much having a lack of time, but rather a lack of interest in the course content having got a chance at working on real projects in a live environment. Most people who have been graduated a little while also find this - when looking back at uni work, it seem to be much more trivial from a problem solving point of view which I found to be true and I found key to uni work to actually be your ability to prove though how you talk about something that you comprehensively understand the basics.After completing uni I then returned full time to Adfero purely in the developer role which is where I've now been for almost a year and have now also taken on the title of "Information Systems Architect" where I'm working on some of the more high level design problems within the products.What I'm wanting to share on this blog is some of the interesting things I've learnt myself over the last year, the things they don't teach you in uni and pretty much anything else I find interesting! My personal favorite areas are text indexing, search and particularly good software engineering design - good design combined with good code makes the first step towards a well-written, maintainable piece of software.Hopefully I'll also be able to share a few of the products I've worked on, the mistake I've made and the software problems I've inherited from previous developers and had to heavily re-factor.

• Cookie access within a HTTP Class

  - by James Jeffery

  I have a HTTP class that has a Get, and Post, method. It's a simple class I created to encapsulate Post and Get requests so I don't have to repeat the get/post code throughout the application. In C#: class HTTP { private CookieContainer cookieJar; private String userAgent = "..."; public HTTP() { this.cookieJar = new CookieContainer(); } public String get(String url) { // Make get request. Return the JSON } public String post(String url, String postData) { // Make post request. Return the JSON } } I've made the CookieJar a property because I want to preserve the cookie values throughout the session. If the user is logged into Twitter with my application, each request I make (be it get or post) I want to use the cookies so they remain logged in. That's the basics of it anyway. But, I don't want to return a string in all instances. Sometimes I may want the cookie, or a header value, or something else from the request. Ideally I'd like to be able to do this in my code: Cookie cookie = http.get("http://google.com").cookie("g_user"); String g_user = cookie.value; or String source = http.get("http://google.com").body; My question - To do this, would I need to have a Get class, and a Post class, that are included within the HTTP class and are accessible via accessors? Within the Get and Post class I would then have the Cookie method, and the body property, and whatever else is needed. Should I also use an interface, or create a Request class and have Post and Get extend it so that common methods and properties are available to both classes? Or, am I thinking totally wrong?

• What am I missing about PHP?

  - by Aerovistae

  It's like this mythical thing that a dominating portion of developers say is just the best option for back-end development, a part of development about which I know virtually nothing beyond the absolute basics. So I've looked up PHP tutorials a bunch of times, trying to figure out why it's so powerful and common, but it's annoying as hell-- all the tutorials treat you like a new programmer. You know, this is how you make an If Else statement, here's a for loop, etc. The "Advanced Topics" show you how to make POST and GET statements and whatnot. But there must be more to it! I don't get it! That's practically no different from JavaScript. What am I missing about this language? What else can it do? Where's the power and versatility? I've heard it called a function soup; where are all the functions? Please chide me. I'm clearly missing something.

• Start a new project. Where is the inspiration ?

  - by Kakawait

  The question may seem strange at first glance ... And I may be alone in this situation. But currently I want to improve my skill through learning new framework. however, do a simple "HelloWorld" application does not satisfy me. I think a practical project is required to apprehend the basics of a framework. I know there is many scholar-like project like design a library manager or CMS. But I have recently planned to learn ~3 differents frameworks and I can't find any motivations through "unexciting" project. In the end I have not started any framework ... I'm aware of I do not develop the project of the year ... I'm just looking for something a bit exciting. I do not expect any project subject, anyway stimulation provided by a project is something subjective. But I want to know your inspiration ! (or method to learn framework ^^) I'm talking about web-dev framework but I'm open to any kind information ! Kind regards.

• No sound after upgrading to Ubuntu 11.10 from win7

• Commands in Task-It - Part 1

  Download Source Code NOTE: To run the source code provided your will need to update to the RC (release candidate) versions of Silverlight 4 and VisualStudio 2010. In recent blog posts, like my MVVM post, I used Commands to invoke actions, like Saving a record. In this rather simplistic sample I will talk about the basics of Commands, and in my next post will get deeper into it. What is a Command? I remember the first time a UI designer used the word "command" I wasn't really sure what she was referring to. I later realized that it is just a term that is used to represent some UI control that can invoke an action, like a Button, HyperlinkButton, RadMenuItem, RadRadioButton, etc. Why should we use Commands? I'm sure you're familiar with the code behind approach of handling events. For example, if you had a Button and a RadMenuItem that ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Learning a new concept - write from scratch or use frameworks?

  - by Stu

  I have recently been trying to learn about MVVM and all of the associated concepts such as repositories, mediators, data access. I made a decision that I would not use any frameworks for this so that I could gain a better understanding of how everything worked. I’m beginning to wonder if that was the best idea because I have hit some problems which I am not able to solve, even with the help of Stack Overflow! Writing from scratch I still feel that you have a much better understanding of something when you have been in the guts of it than if you were at a higher level. The other side of that coin is that you are in the guts of something that you don't fully understand which will lead to bad design decisions. This then makes it hard to get help because you will create unusual scenarios which are less likely to occur when you working within the confines of a framework. I have found that there are plenty of tutorials on the basics of a concept but very few that take you all the way from novice to expert. Maybe I should be looking at a book for this? Using frameworks The biggest motivation for me to use frameworks is that they are much more likely to be used in the workplace than a custom rolled solution. This can be quite a benefit when starting a new job if it's one less thing you have to learn. I feel that there is much better support for a framework than a custom solution which makes sense; many more people are using the framework than the solution that you created. The level of help is much wider as well, from basic questions to really specific, detailed questions. I would be interested to hear other people's views on this. When you are learning something new, should you/do you use frameworks or not? Why? If it's a combination of both, when do you stop one and move on to the other?

• How to tackle an experienced C# Programmer?

  - by nandu.com

  I am a noob in c# and asp.net developing. I have spent 6 months in design and another 6 in sql and asp.net programming. I just know the basics of asp.net and C#. I was programming as per the instruction of my tech leads and all good things changed in a day. :( All my tech leads (2+ experienced) left the company complaining about salary. And instead of those, company has recruited a 5+ experienced programmer cum tech lead (who is very strict), he is expecting me to code anything he says. Previous seniors of me, would say 'use ajax for this, use query for this instead of coding' and so on. I will do it exactly. I am not experienced enough to perform it myself. Now I am in a dilemma. I want to stay in the company and learn some more, but this new tech lead is expecting me to learn everything myself (he is telling me to learn jquery, javascript menus, session and chart in .Net, and so on and do things myself without asking him anything...I mean anything) :(((( PLease suggest to me some good tips to handle him. I think all programmers world wide would have faced a similar problem atleast once in the big programming life. So please..help .. 911

• Poor backlink profile - search rankings not updated for 2+ months

  - by fistameeny

  I am carrying out some work on a website that is a PR2 with a few good quality, relevant backlinks (PR4-6). It has a presence on Twitter that is updated regularly, a Google Places listing, and listings on some decent directories (Qype etc). The site was rebuilt into Drupal 7 two months ago, with all the basics done - URL rewriting, XML Sitemap submitted to Google, and most importantly, good quality, structured content. I've noticed that Google is still showing "old" URL's from the previous version of the site that was ditched 8 weeks ago. I think the site may be penalised under the Penguin update, as a previous SEO company created many low quality links from link farms/directories. My question is what the correct way to deal with this is. Bing Webmaster Tools can "disavow" links, and I guess I can attempt to contact the link farms to have them removed. I've already submitted a request to Google to request that we have the penalty removed as we're trying to tidy up a bad history. We submit updated sitemaps to Google and Bing daily, and have built some further decent quality, relevant links. Is there anything further I can do?

• Finding the best practice for a game simulating tool

  - by Tougheart

  I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

• Python Web Applications: What is the way and the method to handle Registrations, Login-Logouts and Cookies? [on hold]

  - by Phil

  I am working on a simple Python web application for learning purposes. I have chosen a very minimalistic and simple framework. I have done a significant amount of research but I couldn't find a source clearly explaining what I need, which is as follows: I would like to learn more about: User registration User Log-ins User Log-outs User auto-logins I have successfully handled items 1 and 3 due to their simple nature. However, I am confused with item 2 (log-ins) and item 4 (auto-logins). When a user enters username and password, and after hashing with salts and matching it in the DB; What information should I store in the cookies in order to keep the user logged in during the session? Do I keep username+password but encrypt them? Both or just password? Do I keep username and a generated key matching their password? If I want the user to be able to auto-login (when they leave and come back to the web page), what information then is kept in the cookies? I don't want to use modules or libraries that handle these things automatically. I want to learn basics and why something is the way it is. I would also like to point out that I do not mind reading anything you might offer on the topic that explains hows and whys. Possibly with algorithm diagrams to show the process. Some information: I know about setting headers, cookies, encryption (up to some level, obviously not an expert!), request objects, SQLAlchemy etc. I don't want any data kept in a single web application server's store. I want multiple app-servers to be handle a user, and whatever needs to be kept on the server to be done with a Postgres/MySQL via SQLAlchemy (I think, this is called stateless?) Thank you.
