• How to get experience in large scale databases?

  - by Justin

  I have written applications that are very small scale and the code I write works fine for them. But I have often wondered how the server side code I write would scale up from 100s of queries per day to millions. Also when looking at possible jobs/projects, people are often looking for developers with experience in this sort of high traffic database design so I would at least like to be able to say, I havent gotten to work on a project that was this popular, but I at least have tried to simulate it. Are there tools or frameworks that can generate a lot of traffic or at least simulate what would happen with traffic on different orders of magnitude so I could get some practice writing optimized code for higher traffic applicaitons?

• What is the standard way of delivering HTML5 games to portals and such?

  - by Bane

  Let me explain what I mean by "standard way of delivering"... Think about Flash games sites. Flash games can be delivered as a single file, either hosted by the site, or, I guess, provided by someone else. HTML5 games, on the other hand, don't have something so standard. Usually, they have their own page, and portals just link to that page. I think that it greatly hinders the purpose of that portal, because, well, you want people to stay on your site and look for other games. Now, I think that a some kind of iframe way of delivering games would help solve this problem greatly. I saw some games doing that, and they were often included on tutorial sites to show a live example, which is obviously a great thing. So, is there a standard at all? Any suggestions? Can you create a game that just preloads itself in an iframe (I heard something about a "single document" or something)?

• What is the Best Way to Incentivize a Team of Developers?

  - by Seth P.

  I know in advance that people are going to see this question and think "free Red Bull." But I am actually looking for the best way to tie rewards for developers to the company's long-term goals. For example, assuming a team is working on the same software product, would it be best to reward each developer based on the condition of the final product? They are a team after all, and this will ensure that they are all working towards the common goal of getting the product out. However, this ignores the fact that some developers are stronger than others and some work harder than others. In your experience, what is the best way to incentivize a team of developers?

• Steps to manage a large project [closed]

  - by l46kok

  Software development is an area where parallel development to its fullest form is very difficult to achieve, although you could get reasonably close with the right design. This is especially true for game development. That being said, if you are designing a game from scratch from engine to front end, what steps should be taken in order? How would you efficiently manage your project and your team? I'm asking because several people and I are interested in working on a relatively large project for learning purposes. Initially, we were going to use a proprietary engine like Unity, but since we wanted to learn how the engine works, we're going to start from bottom. I'd appreciate any suggestions that you guys can provide me.

• Programming Interview : How to debug a program?

  - by Jake

  I was recently asked the following question in an interview : How do you debug a C++ program ? I started by explaining that programs may have syntax and semantic errors. Compiler reports the syntax errors which can be corrected. For semantic errors, various debuggers are available. I specifically talked about gdb, which is command line, and Visual Studio IDE's debugger, which has a GUI, and common commands. I also talked about debug and release version of code, how assertions should be used for debug build, how exceptions helps in automatic cleanup & putting the program in valid state, and how logging can be useful (e.g. using std::clog). I want to know if this answer is complete or not. Also, I want to hear how other people will go about answering this question in a structured manner ? Thanks.

• Storing E-mail addresses more efficiently in SQL Server

  A lot of people are storing large quantities of e-mail addresses in their systems. Since a large percentage of any system's user base is going to be supplying e-mail addresses from a few of the vastly popular providers (such as GMail and Hotmail), we are storing the "@gmail.com" and "@hotmail.com" parts of those addresses on disk over and over and over again.

• Is it common in companies that non-techs are doing analyzes

  - by Kubi

  It's been 2 months since I started working at an international big consulting company. I like my colleagues personally but it's like a joke since my first day. Analysts (people who has no idea about the tech. background) are planning the workflow and functions. In my case, none of my friends here even wrote even a single line of html. When I say Html, I doubt if they know what I mean. But they are deciding about really key decisions in a web system implementation project. Is this always like this?

• when should a database table be broken into multiple tables with relations?

  - by GSto

  I have an application that needs to store client data, and part of that is some data about their employer as well. Assuming that a client can only have one employer, and that the chance of people having identical employer data is slim to none, which schema would make more sense to use? Schema 1 Client Table: ------------------- id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), employer_name varchar(255), employer_phone varchar(255), employer_address varchar(255), employer_city varchar(255), employer_state char(2), employer_zip varchar(16) **Schema 2** Client Table ------------------ id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), Employer Table --------------------- id int name varchar(255), phone varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16) patient_id int Part of me thinks that since are clearly two different 'objects' in the real world, seperating them out into two different tables makes sense. However, since a client will always have an employer, I'm also not seeing any real benefits to seperating them out, and it would make querying data about clients more complex. Is there any benefit / reason for creating two tables in a situation like this one instead of one?

• Ops Center and Oracle Solaris 11

  - by user12609425

  There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

• How should one deal with egotistic cowokers? [closed]

  - by Anonymous

  One of my fellow coworkers, who is older than me, is very egotistic. (He is senior while I am junior.) He is always over confident in what he is doing, but most of the time he does not think things through. When I suggest that he does something else or ask him what he is doing, he will not answer but tells me to do as he says. I always end up being the person who cleans up his mess. I want to know how to deal with egotistic people?

• Does a person's day-to-day neatness (outside of programming) relate to quality and organization in programming?

  - by jiceo

  Before anyone jumps into any conclusion, I had a discussion with a friend (who's not a programmer at all) about the relationship between a person's neatness habit and the degree of neatness generally shown in works by the same person. This led me to think about this situation: Let's imagine you knew a programmer whose house was very messy. This person's lifestyle is messy by nature. On his desk there are books, papers, STUFF, piled everywhere including on the floor, mixed with dirty clothing, with no obvious organization at all. If you asked him to find a book he hasn't touched for at least a week from the cluster of chaos, he would take at least an hour to do so. How likely is it that he will produce very clean, consistent, and organized code that other people can use? Are there CS legends that are/were notoriously messy in day-to-day habits?

• Best way to redirect in IIS

  - by stephmoreland

  We have a website that has two URLs (one for the US side and another for the Canadian side which is then broken into Canadian English and Canadian French). For the purposes of my question, I will write as: www.us_url.com (US) www.canada_url.ca/ca_en/ (Canadian English) www.canada_url.ca/ca_fr/ (Canadian French) To make sure people are on the correct site, what do I do if they go to the US URL with Canadian English content (e.g. www.us_url.com/ca_en/canada.asp) but I want to make sure the URL is the Canadian one (e.g. www.canada_url.ca/ca_en/canada.asp) so it shows up properly in Google Analytics. We're using IIS 7 and classic ASP.

• Does e-commerce platform matter for branding

  - by c s h

  The place I work is now looking into developing a new e-commerce site on the Magento platform. Magento will fill all of our needs. I was just wondering if it is in anyway unprofessional doing it this way (Impression is something we are really worried about), will people who visit the site look at our business different knowing we used Magento or any other e-commerce platform. There are ways to find out. I use Chrome Sniffer to find out what platforms are used to develop each site, there are other tools available for different browsers. Bottom-line: Will an e-commerce platform affect the trust in my brand?

• Anyone know about AppDynamics? Does Microsoft already have something similiar? Event viewer? Im confused

  - by punkouter

  We have a big collection of java (80%) and .Net (20%) apps.. And the people in charge want a way to monitor the applications somehow. So they told me they are interested in AppDynamics? I have spent a bit looking into it but I still don't get it. Can someone tell me what its about ? From my understanding it seems like you would someone inject the AppDynamics API in your code to tell about differnt events that occur? So sounds like Event Viewer ? I am on the .NET side of this and seems to me we can just write data to a log and report off of that data.. I don't get what the additional complexity of using'AppDynamics' does. Maybe it is overkill ??

• Theme sometimes fails to load on some UI elements

  - by Neil

  I have no idea if this error as been seen before or not, I have looked around and found people saying they have errors that sound the same but none of the fixes work, my issue is that sometimes the theme does not load some parts of the UI, (the buttons and icons in this case) but the rest is just fine (window bars e.t.c) so I have no idea what the issue is, it works just fine for the most part but sometimes has this bug, if you restart the system it tends to fix it for some time so its hard to see how it could be a graphic card error, however I am very new to linux systems so I may be missing someting very fundamental here. Thank-you in advance. This image shows my problem

• How to deal with readers requesting free advice / support on my blog? [closed]

  - by russau

  I have a handful of popular articles on my blog (nothing huge), and they attract the occasional developer who wants help implementing some code grabbed from my blog. Now I'm getting people who haven't made any attempt to learn the code, email me their code, and expect me to trace it through for them. I'm sure anyone with a half-popular blog gets similar requests. What's the best way to deal with this scenario? I want to put together a boilerplate response including these points: How far have you gone with this on your own? (is it any benefit for anyone if I say they are being imposing) I'm happy to help with any problems you find in my code Point them to other forms of help such as stackoverflow, diagnostic tools relevant to the topic.

• Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

  - by xref

  Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

• Language-independent sources on 2D collision detection [on hold]

  - by Phazyck

  While making a Pong clone with a friend, we had to implement some 2D collision detection. For research purposes, my friend dug up a book called "AdvancED Game Design with Flash" by Rex Van Der Spuy. This book was clearly targeted at implementing 2D collision detection in ActionScript, and I also have some problems with how the concepts are presented, e.g. presenting one method as better than another, without explaining that decision. Can anyone recommend some good material on 2D collision detection? I'd prefer it if it kept the implementation details as language-independent as possible, e.g. by implementing the concepts in pseudo-code. Language-specific materials are not completely unwelcome though, though I'd prefer those to be in either Java, C#, F# or Python or similar languages, as those are the ones I'm most familiar with. :-) Lastly, is there perhaps widely known and used book on collision detection that most people should know about, like a 'the book on 2D collision detection'?

• Should I work for free while applying for a job?

  - by Jevgeni Bogatyrjov

  An employer usually asks a candidate to do a small project at home ("homework") as a part of applying for a job. Last time I applied for a job (as a web developer), there were aproximately 10 applicants who were all given different tasks. Despite the fact that there was only one vacancy, the company used the work of all of the candidates in one of its projects. Actually, it is quite reasonable for a company to create these "vacancies" just to make people work for free - I estimate, that aproximately 2 weeks of programmer's work was saved with all of the job applications that company had on one vacancy. Is this a common practice and how can you protect yourself from working for free in the future? Have you seen this during your career?

  Accept credit card Allow me to automatically credit a customers' account. We're not selling e-book. We're selling a credit to our account. So it's important that customers do not get credited twice. Easy to program and integrate with our sites. Have affiliate programs.

  - by Aldo

  i have a dell N4110 laptop, and i want to know if the driver is installed and working well, something like the device manager in windows , or another way to know if a device is driverless or if the device might have a better driver, like my mousepad, in windows it have multi-touch gestures , that scrolls or zoom with two fingers (like an ipod) but in ubuntu it just works the right part as a scroll bar, so maybe it is installed one driver, but i need other one that uses well my devices. and the grphics card, i have not idea if it is well installed or isn't. i have a Intel 3000hd graphics card. thank you for your time. have a nice day people! =D

• Should I be using a game engine?

  - by Kyle

  I'm an experienced programmer, but I'm completely new to making games. I'm thinking of making an iPhone game that is similar to a 2d tower defense type game. In the web programming world, it would be a big waste of time to make a website without using some sort of web framework (eg ruby on rails). Is that the same for making games? Do people mostly use some sort of framework/game engine for making a game? If so, what are the popular ones for iOS?

  I've a content website that presents ads. Now, my team want to optimize it for a better experience for the users. (we really believe our ads are good for our users.) We are sure that every website deals with this issue and there must be some known ways and methods to deal with it, that smart people thought of before. so what i'm looking is a tested, working method to optimize ads. for example: if i was asking about optimizing my website in Google, I would expect you to answer me: learn SEO if i was asking about optimizing the use of my website: usability testing. navigation: information architecture what is the field that deals with optimizing ads?
