• Developing a live video-streaming website

  - by cawecoy

  I'm a computer science student and know a little about some technology to start developing my website, like PHP, RubyOnRails and Python, and MySQL and PostgreSQL for Database. I need to know what are the best (secure, stable, low-price, etc) to get started, based on my business information: My website will be a live video-streaming one, similar to livestream.com We need to provide a secure service for our customers. They need to have a page to create and configure their own Live-Streaming-Videos, get statistics, etc. We work with Wowza Media Server ruuning on an Apache Server In addition, I would like to know some good practices for this kind of website development, as I am new to this. Thanks in advance!

• How much help should I give during technical interviews?

  - by kojiro

  I'm asked to perform or sit in during many technical interviews. We ask logic questions and simple programming problems that the interviewee is expected to be able to solve on paper. (I would rather they have access to a keyboard, but that is a problem for another time.) Sometimes I sense that people do know how to approach a problem, but they are hung up by nervousness or some second-guessing of the question (they aren't intended to be trick questions). I've never heard my boss give any help or hints. He just thanks the interviewee for the response (no matter how good or bad it is) and moves on to the next question or problem. But I know something about the rabbit hole that defeat and nerves can lead you down, and how it disables your mind, and I can't help wondering if providing a little help now and then would ultimately help us end up with more capable programmers instead of more failed interviews. Should I provide hints and assistance for befuddled interviewees (and if so, how far should I go while still being fair to the more prepared candidates)?

• How do I deal with code of bad quality contributed by a third party?

  - by lindelof

  I've recently been promoted into managing one of our most important projects. Most of the code in this project has been written by a partner of ours, not by ourselves. The code in question is of very questionable quality. Code duplication, global variables, 6-page long functions, hungarian notation, you name it. And it's in C. I want to do something about this problem, but I have very little leverage on our partner, especially since the code, for all its problems, "just works, doesn't it?". To make things worse, we're now nearing the end of this project and must ship soon. Our partner has committed a certain number of person-hours to this project and will not put in more hours. I would very much appreciate any advice or pointers you could give me on how to deal with this situation.

• Black Hat Hackers vs Programmers?

  - by Matt Ridge

  This came up with another question I had here, I have decided on a programming verification system that requires a hardware verification system, a software key, and a name/password system. Now people are saying that hackers will bypass any new security, which may be true, but I have a few questions. There has to be a balance between programmers programming and hackers stealing software, otherwise programs wouldn’t be made, and we wouldn’t be where we are today. What is that balance? 5%, 10%, 20%, 50%? What is too much security for the end user? What is too little security so the hacker can just push through without issue? If your software becomes popular, what should you expect or accept as acceptable loss? Why should we accept black hat hackers as a way of life?

• Where to find clients who are willing to pay top dollar for highly reliable code?

  - by Robin Green

  I'm looking to find clients who are willing to pay a premium above usual contractor rates, for software that is developed with advanced tools and techniques to eliminate certain classes of bugs. However, I have little experience of contracting, and relatively few contacts. It's important to state that the kind of tools and techniques I'm thinking of (e.g. formal verification) are used commercially extremely rarely, as far as I'm aware. There is kind of a continuum of approaches to higher reliability, with basic testing and basic static typing at one end and full-blown formal verification at the other, but the methods I'm thinking of are towards the latter end of the spectrum.

• Build a LEGO Creation without Leaving Your Cube

  - by Jason Fitzpatrick

  Just because you’re stuck at your desk doesn’t mean you can’t sneak in a little fun. At BuildWithChrome you can slap together virtual LEGO bricks with ease. The site, a collaboration between Google and LEGO, shows you a massive map of Australia and New Zealand covered in thousands of LEGO base plates. Zoom in, select a base plate, and get building. The block selection is fairly limited (you can work with the kind of blocks you’d find in a generic LEGO brick pack) but it’s still quite a bit of fun. When I took it for a test drive, I started simple by building a house-like structure: With the addition of a few more pieces it would be possible to pull off the wizard shop my wife and daughter just built: How to Banish Duplicate Photos with VisiPic How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

• Community Day at SOS Kinderdorf Bambous

  Easter is not only an occassion of public holidays but an opportunity to share and celebrate with your neighborhood. The team of IOS Indian Ocean Software Ltd. spent Easter Monday with the children and "mothers" of SOS Children's Village in Bambous. Together with the employees' family members we enjoyed some wonderful hours together. Starting the community day with a common lunch, IOS contributed mainly stationery, educational gifts and games like Scrabble or Sudoku. And of course, a little give-away with chocolate eggs... The kids are aged between 5 and 18 years. They live together with their village mothers in so-called family houses. The SOS Kinderdorf in Bambous is quite new and started their operations back in 2003, with an official inauguration in May 2005. Actually, I'm really happy about this event and I am looking forward to IOS next community activity. Community off-line and for real people, not only virtual!   PS: Article in L'Express of 09.04.2010

• Are there any good reasons to intentionally serve a new web site in Quirks mode?

  - by wsanville

  I was a little surprised that Amazon's site doesn't specify a doctype, and is rendered in quirks mode. What could possibly be the reason for this? I understand what quirks mode is and why doctypes were introduced, but I can't understand why this would be intentionally left off. I guess it might simplify markup if they're trying to support ancient browsers, but isn't that like shooting yourself in the foot when it comes to modern browsers, especially when their site is so Javascript rich? Does this level the playing field when it comes to supporting really old browsers? Is there something else I'm missing?

• Artist, Looking to lean how to program games, where do I start? [on hold]

  - by Christopher Hindson

  I have bean an artist for many years now I am very comfortable with using Photoshop and Flash but I want to learn how to but together my own games, I bean doing my own research into this and at the moment I am at little bit stuck on witch direction to go down. So my question is witch programming language should I learn? I have already bean looking into this what i understand is that Gamemaker with its built in language (GML) is one of the most friendly to people who are new to the game making world. I have played around with this program and was pretty happy with it but I want more also you can use Unity with language such as C and javascript and then games built with Java witch looks interesting. One more thing before you send your answer in at this moment in time I would only be able to make 2D game but 3D isn't out of the picture.

• Microsoft Interview Attire

  - by Michael

  Hi all, I have an interview with Microsoft in a week and am wondering what to wear. The recruiter said Business Casual but that means very little to me. I'm sure some people here have already had interviews at MS. Anyone care to share what the interviewers were wearing? Would I be out of place with jeans and a polo shirt? Honestly, I feel more comfortable with casual clothes (some people are the opposite) but I don't want to look under dressed either. Thanks for the tips.

• Is writing software in the absence of requirements a skill to possess or a situation I should avoid?

  - by Brian Reindel

  I find that some software developers are very adept at this, and often times are praised for their ability to deliver a working concept with abstract requirements. Frankly, this drives me crazy, and I don't like "making it up" as I go. I used to think this was problematic, but I've started to sense a shift, and I'm wondering if I need to adjust my thought (and programming) process when given very little direction. Should I begin to acquire this ability as a skill, or stick to the idea that requirement's gathering and business rules are the first priority?

• Getting started with ClojureScript and Google Closure

  - by Andrea

  I would like to investigate whether ClojureScript, with the associated Google Closure library is a reasonable tool to build modern, in-browser, Javascript applications. My current Javascript stack consists of jQuery, Backbone and RequireJS with the possible additions of some widgets libraries like jQueryUI or KendoUI. So it will be quite a big leap (I already know how to work in Clojure, although I have little experience). What is a good roadmap to do so? Should I learn the Google Closure library first, or can I grasp it together with ClojureScript? One thing I am concerned about is the overall application structure. Backbone is rather opinionated on how to organize your application. I am not sure whether Google Closure also includes some components to help with the design of the application. And, if this is the case, I do not know how to tell whether this structure will port to ClojureScript or a ClojureScript application will require a different organization anyway, and only use - say - the widgets and DOM manipulation features of Closure.

• Building a website, want to use java

  - by Robb

  I'd like to make a simple-ish website that is essentially a small game. Key strokes are to be processed and sent to a server (already acquired and should support SQL and JSP, I believe) which then translate to a location and written to the DB. SQL queries are to be used to retrieve these locations and written to other clients connected to the website. Their page is to be updated with these locations. I have working knowledge of Java, jQuery/Ajax, SQL and JavaScript but I'm unfamiliar with JSP and how everything hooks up. I'm aware of the MVC paradigm as well. For my little game idea, would these technologies work? Am I over thinking this and can make it much easier to implement? What might be a good tutorial or example to study?

• Is it convenient to use a XML/JSON generated based system? [closed]

  - by Marcelo de Assis

  One of my clients insists that we missed a requisite for the project(a little social network, using PHP + MySql), is that all queries are made from XML / JSON static files (using AJAX) and not directly from the database. Edit: The main reason, stated by client, is a way to economize bandwith. Even the file loading, has to be using AJAX, to avoid server side processing. We will still use a database to store and insert data. These XML / JSON files will be (re) generated whenever any data is changed by CMS or users. As the project was developed without this "technique", we'll have a lot of work ahead, so I would like to avoid that. I'm asking if it's convenient to use a XML generated based system, because I think a database is already "optimized" and secure to deal with a lot of data traffic. Other issue I'm afraid of, is a chance of conflict when a user is trying to read a XML/JSON which is being just generated.

• Is it any good to use binary arithmetic in a C++ code like "C style"?

  - by user827992

  I like the fact that the C language lets you use binary arithmetic in an explicit way in your code, sometimes the use of the binary arithmetic can also give you a little edge in terms of performance; but since I started studying C++ i can't really tell how much i have seen the explicit use of something like that in a C++ code, something like a pointer to pointer structure or an instruction for jumping to a specific index value through the binary arithmetic. Is the binary arithmetic still important and relevant in the C++ world? How i can optimize my arithmetic and/or an access to a specific index? What about the C++ and the way in which the bits are arranged according to the standard? ... or i have taken a look at the wrong coding conventions ... ?

• Adding included columns to indexes using SMO

  A question came up on the SQL Down Under mailing list today about how to add an included column to an index using SMO. A quick search of the documentatio didn't seem to reveal any clues but a little investigation turned up what's needed: the IndexedColumn class has an IsIncluded property. Index i = new Index (); IndexedColumn ic = new IndexedColumn (i, "somecolumn" ); ic.IsIncluded = true ; Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!...(read more)

• Starting my first project and have no idea about it. Guide please.

  - by Chankey Pathak

  I am a Computer Science student (6th semester). I want to make a project and I have a team of 4 people (My friends). So we are 5 people and we have decided to make a "Web based file explorer". The project will be similar to THIS one. How should we start with this project? We guys don't know much about programming. I know Java a little and I am a RHCE so can handle the server and all such administrative stuffs. Since this is our first project so we guys have no idea how we'll make it? I know Java and other guys in the group knows C#, ASP.NET, PHP, SQL and Joomla. Please guide and give your suggestions. Thank you. PS : Perhaps my question is not complete, if you want more information then leave a comment I will edit the question.

• Android/Java AI agent framework/middleware

  - by corneliu

  I am looking for an AI agent framework to use as a starting point in an Android game I have to create for a university research project. It has been suggested to me to use JADE, but, as far as I can tell, it's not a suitable framework for games (at least for my game idea) because it runs in a split-execution mode, and it needs an always-active network connection to a main host. What I want is just a little something to give me a headstart. I am willing to adjust the game's features to the framework because it's more of a mockup game, and the purpose is to compare the performance of a couple of agents in the game world. The game will be very simplistic, with a minimal UI that displays various stats about the characters in the game (so no graphics, no pathfinding). Thank you.

• Manual bootstrapping with Juju on VPS

  - by aaronfc

  I recently bought a VPS (OpenVZ) with Ubuntu 13.04. Lately I've read about Juju and I thought it would match my needs on my brand new VPS as I want to easily configure Hadoop, Wordpress, Graphite and other services. I tried the juju-local approach but I got an error while installing it: http://paste.ubuntu.com/6373143/ So I got to #juju IRC channel and I was told to use "Manual bootstrapping" and create a question here in order to get more info as it seems is something under development. Could anybody help me getting Juju to work on my VPS? Did any had the same problem? Thanks in advance! EDIT: After some more research (and after reading my own question) I think I should clarify a little more the situation. What I want is a manual provider to allow me manage my VPS from Juju. I know there might be a work in progress and I would appreciate any info regarding it's state and any possible solution :)

• Has programming ruined your perception of round numbers?

  - by Jon Purdy

  Most of the world works in base 10 nowadays, but as programmers working on binary systems, we constantly find ourselves working with powers of 2. While most people consider integer multiples of powers of 10 "nice and round" and somehow aesthetically superior, I found early on in my programming adventures that multiples of powers of 2 feel much more intuitively round to me: fewer factors, of course. I'm much more likely to lay out a Web site using, say, 8- or 16-pixel margins rather than 10 or 20, and when someone remarks that 128 is an insanely arbitrary number of ounces to be in a gallon, I have to smile a little inside at how, just perhaps, the U.S. system might be superior to metric in one small way. I'm just curious: has programming ruined (read: altered) your perception of the roundness of a number?

• Trying not to get ahead of myself but it is hard!

  - by Andrew

  Well I made a 5 year plan for myself (11years-16years) I am pretty good at Java, HTML, and PHP. I have already done some end projects: Small Java Platform Game A Small Polynomial Solver A Small Image Sharing Site A Chess Website: chesslounge.net I am currently doing some Android Development and so far I have made a program that Vibrates, Blinks the Light, or Creates a custom status message based on the user input. And a program that rotates a pyramid with a texture. My question is: Should I stick to what I am doing or Learn something a little new? I am itching to do C++, but what is your advice?

• .NET Libraries Cost More Than Windows?

  - by Kevin Mark

  When looking into libraries to make my programming life a little bit easier I've (almost) always been disappointed by the prices offered. For instance, Actipro's WPF Studio is $650. I suppose that's worth it if you plan to make money from the use of those controls. But take a look at, say, Windows. Windows 7 Ultimate is just about $220. I consider Windows to be a far more complex and "worth-it" product/purchase than a library that runs on it. Why the significant difference in pricing? Do libraries really need to be so expensive, or do they need to charge more in order to make a decent some of money?
