• As a developer, how do I learn sales? [closed]

  - by Dan Abramov

  I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

• "Opportunity" to take over maintenance of a small internal website. What should I do?

  - by Dan

  I have been offered an "opportunity" to take over maintenance of a small internal website run by my group that provides information about schedules and photos of events the groups done. My manager sent me the link to the site and checked it out. The site looked clean and neat but loaded in ~5 seconds. I thought this was a little long considering the site really didn't contain a lot of content. This prompted me to take a look under the hood at the pages source code. To my horror it'd been totally hacked together using nested tables! I'm new so I really can't say no to this "opportunity" so what should I do with it? Every fiber of my being feels that the only correct thing to do is over hall the site using CSS, Div's, Span's and any other appropriate tags that a sane/good web developer would used to begin with instead of depending on the render incentive magic of tables. But I'd like to ask programmers with more experienced then me, who have been in this situation. What should I do? Is my only realistic option to leave the horror as is and only adjusting the content as requested? I'm really torn between good development and the corporate reality I'm part of. Is there some kind of middle ground where things can be made better even if they're not perfect? Thanks ahead of time.

• Is there a Source Insight alternative?

  - by hansioux

  I am not a developer, but for my work I trace a lot of codes. It is actually rather difficult reading other people's code, especially for bigger projects. Source Insight is a great application that stores all the symbols in a data base, so you can see a new function being called, click on it and see how the function is written. You can see all the referrer of a object or jump to a caller. You don't need to break the train of thought and think up shell commands just to find these things every time you ran into a new variable/structure/function from some other files. I have it running on WINE, but there are little glitches that sometimes gets in the way. I know people will mention C-scope, I've tried it, but it really isn't the same. So, with so many huge open source projects out there for Ubuntu, are there native tools to help read them efficiently? EDIT: Thanks for the suggestions, but does CODE::BLOCKS or CodeLite provide abilities to see the function that the mouse clicked on without jumping to it, so I can see the caller and callee at the same time?

• Do you know how to move the Team Foundation Server cache

  - by Martin Hinshelwood

  There are a number of reasons why you may want to change the folder that you store the TFS Cache. It can take up “some” amount of room so moving it to another drive can be beneficial. This is the source control Cache that TFS uses to cache data from the database. Moving the Cache is pretty easy and should allow you to organise your server space a little more efficiently. You may also get a performance improvement (although small) by putting it on another drive.. Create a new directory to store the Cache. e.g. “d:\TfsCache\” Figure: Create a new folder Give the local TFS WPG group full control of the directory   Figure: You need to use the App Tier Service WPG In the application tier web.config (~\Application Tier\Web Services\web.config) add the following setting (to the appSettings section). Figure: The web.config for TFS is stored in the application folder <appsettings> ... <add value="D:\" key="dataDirectory" /> ... </appsettings> Figure: Adding this to the web.config will trigger a restart of the app pool Figure: Your web.config should look something like this The app pool will automatically recycle and Team Web Access will start using the new location.  If you then download a file (not via a proxy) a folder with a GUID should be created immediately in the folder from #1.  If the folder doesn’t appear, then you probably don’t have permissions set up properly.

• How to cover the widest range of computers when publishing?

  - by DevilWithin

  When you plan a game, or even when you already made a game, and its time to publish, you wonder how much of your audience is covered by the game technology demands. I'm directing this essentialy to casual games, as I constantly see people having old laptops and being unable to replace them. Laptops with integrated cards whose OpenGL version doesn't even support textures larger than 1024x1024. These people may be avid gamers as well, and a reasonable share of the audience to consider giving them the chance to play casual games, once they cannot play any blockbusters. As I've seen happening, a very "noticeable" example is Angry Birds. It's gameplay is merely casual (I think nobody disagrees here) and still, it uses so high resolution textures that at least OpenGL 2.0 or around is needed, which blocks away a lot of people. So, the actual question is: what is a good tradeoff for this issue? Would it be better to just sacrifice the texture resolution for everyone, but have more supported hardware? Would it be better to keep the high quality and just slice the textures into smaller ones, sacrificing the performance a little bit? What else? Any ideas about this topic are welcome for discussion.

• What is the point of dynamic allocation in C++?

  - by Aerovistae

  I really have never understood it at all. I can do it, but I just don't get why I would want to. For instance, I was programming a game yesterday, and I set up an array of pointers to dynamically allocated little enemies in the game, then passed it to a function which updates their positions. When I ran the game, I got one of those nondescript assertion errors, something about a memory block not existing, I don't know. It was a run-time error, so it didn't say where the problem was. So I just said screw it and rewrote it with static instantiation, i.e.: while(n<4) { Enemy tempEnemy = Enemy(3, 4); enemyVector.push_back(tempEnemy); n++; } updatePositions(&enemyVector); And it immediately worked perfectly. Now sure, some of you may be thinking something to the effect of "Maybe if you knew what you were doing," or perhaps "n00b can't use pointers L0L," but frankly, you really can't deny that they make things way overcomplicated, hence most modern languages have done away with them entirely. But please-- someone -- What IS the point of dynamic allocation? What advantage does it afford? Why would I ever not do what I just did in the above example?

• How do you structure your shared code so that it is "re-findable" for new developers?

  - by awmckinley

  I started working at my current job about 8 months ago, and its been one of the best experiences I've had as a young programmer. It's a small company, and both my co-developers are brilliant guys. One of the practices that they both have been encouraging is lots of code-reuse. Our code base is mainly C#, and we're using a centralized revision control system. The way the repository is currently structured, there is a single folder in which all shared class libraries are placed (along with unit tests for each library), and our revision control system allows for sharing or linking those libraries out to other projects. What I'm trying to understand at this point is how the current structure of the folder can be made more conducive for finding those libraries again. I've talked to the other developers about this, and they agree that it's gotten a little messy. I find that I am sometimes "reinventing the wheel" because I didn't realize that there was an existing piece of code that solved a particular problem. The issue is complicated further by the fact that we're sharing some code between ASP.NET MVC2, WinForms, and Windows CE projects, and sharing code between applications built against multiple versions of .NET. How do other people approach this? Is the answer in naming the libraries in a certain way or is it preferable to invest in some code-search software? Is the answer in doc comments? Should we be sharing libraries at all or should we simply branch the class libraries for re-use? Thanks for any and all help!

• Modelling work-flow plus interaction with a database - quick and accessible options

  - by cjmUK

  I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

• Repeat use of Schema / Rich Snippets Markup i.e LocalBusiness Data

  - by bybe

  I am unable to find official wording and I'm hoping that some Rich Snippets/Schema Guru can give me some insight into proper usage of repeated content when it comes to using markup. I'm building a site that wants to use Schema as the markup type and the owner would like as much usage as possible. The business name, telephone and address will appear on every page now is it valid or even useful to use Rich Snippets on every page where this information is displayed. For example this information appears in the header, and footer of every page of the site and too give you an example of my current markup see below: <body itemscope itemtype="http://schema.org/LocalBusiness"> <header> <a itemprop="url" href="http://www.domain.co.uk/"> <img itemprop="logo" src="image.png" alt="Company Name Logo" /> </a> <span itemprop="telephone">01202 000 000</span> </header> <div> This is where the content will go</div> <footer> <span itemprop="name">Company Name</span> <span itemprop="description"> A small little bit about this company</span> <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <span itemprop="streetAddress">Address Goes here</span> <span itemprop="addressLocality">Area Here</span>, <span itemprop="addressRegion">Region Here</span> </div> </footer> </body> !-- Local Business Schema Now Closed --> So as you can see above this information will be displayed on every single page.... Is this valid or bad to repeat usage of this information in schema format...

• Player sprite moving slower on iPhone 4

  - by nvillec

  I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

• Tree Surgeon 2.0 - The future on the T4 Express

  - by Malcolm Anderson

  If you've never been a fan of TreeSurgeon (http://treesurgeon.codeplex.com/) then skip this post.However, if have been there have been some interesting developments over the last couple of years.The biggest one is T4Recently Bill Simser wrote a detailed post about the potential future of tree surgeon, called "Tree Surgeon - Alive and Kicking or Dead and Buried" He raised the question:Times have changed. Since that last release in 2008 so much has changed for .NET developers. The question is, today is the project still viable? Do we still need a tool to generate a project tree given that we have things like scaffolding systems, NuGet, and T4 templates. Or should we just give the project its rightful and respectful send off as its had a good life and has outlived its usefulness.For myself, the answer is, keep it.I've spent the last couple of years doing agile engineering coaching and architecture and from my experience, I can tell you, there are a lot of shops out there that would benefit from having Tree Surgeon as a viable product.  Many would benefit simply from having the software engineering information that is embedded in the tree surgeon site be floating around their conversation.Little things like, keep all of your software needed to run the build, with the build in the version control system.Have your developers and the build system using the same build.Have a one-touch buildSeparate your code from your interfacePut unit tests in first, not lastI've seen companies with great developers suffer from the problems that naturally come from builds taking 3 and 4 hours to run.  It takes work to get that build down to 10 minutes, but the benefits are always worth it.  Tree Surgeon gives you a leg up, by starting you off with a project that you can drop into your Continuous Integration system, right out of the box.Well, it used to be right out of the box.  Today, you have to play with the project to make it work for you, but even with the issues (it hasn't been updated since 2008) it still gives you a framework, with logical separations that you can build from.If you have used Tree Surgeon in the past, take a few minutes and drop a comment about what difference it made in your development style, and what you are doing differently today because of it.

• Applications: Some more marble fun!

  - by TechTwaddle

  Well, yesterday night I was watching a tutorial on XNA when I came across this neat little trick. It was a simple XNA application with a Windows Phone logo in it and whenever the user clicked on the device the logo would move towards the click point, and I couldn't resist experimenting with the marble (; The code is written in C# using CF3.5. Here is a video of the demo,   You probably noticed that the motion of the marble towards the click point (destination) is not linear. The marble starts off with a high velocity and slows down as it reaches its destination. This is achieved by making the speed of the marble a function of the distance between marble's current position and the destination, so as the marble approaches the destination point, the distance between them reduces and so does the speed, until it becomes zero. More on the code and the logic behind it in the next post. What I'd like to do next is, instead of making the marble stop at the click point, it should continue to move beyond it, bounce around the screen a few times and eventually come to a stop after a while. Let's see how that goes.

• PHP Battle System for RPG game

  - by Jay

  I posted this a while ago on stackoverflow, they thought it would be better place here, I agree. Essentially I know what I want to accomplish, and I have something to the effect of what I want but I am not satisfied with it. Here's the problem. Each user has some states: STR (how hard they hit), DEF (dodging/blocking attacks), SPD (when they can strike), and STAMINA (basically their endurance in game, if this runs out they can no longer fight and lose) What I need is something like this: UserA Stats: STR: 1,000 DEF: 2500 SPD: 2000 (HP: 1000/1000) UserB Stats: STR: 1,500 DEF: 500 SPD: 4000 (HP: 1000/1000) Because the second user has double the speed, he lands twice the amount of hits on the first user, before he gets hit. Because he has less strength than the first users defence, he will do no, to little damage. This is how the battle would theoretically go: UserB strikes UserA for 0 damage UserB strikes UserA for 0 damage UserA strikes UserB for 500 damage UserB strikes UserA for 0 damage UserB strikes UserA for 0 damage UserA strikes UserB for 500 damage, and sends him to the hospital! I was using this code, which is buggy, and not efficient, I just need a better way to do this: http://pastebin.com/15LiQQuJ Oh, and if anyone has some good ideas on how to improve the concept that would be cool too! It's not that elaborate so I'll be thinking of all sorts of things to make it more dynamic. Thanks.

• Geekswithblogs.net Influencer Programm

  - by Staff of Geeks

  Recently, @StaffOfGeeks announced to a select group of bloggers, the Geekswithblogs.net Influencer Program.  Here is a little detail about the program. Description (from Influencer Page): Geekswithblogs.net is a community of bloggers passionate about contributing information to the world of developers and IT professionals. Our bloggers are some of the best in the world and receive honors on a regular basis for outside companies (such as the Microsoft© MVP Program). The Geekswithblogs.net Influencer Program is our way as Staff of Geeks to show our appreciation for those bloggers who have the greatest influence on the site. Each influencer in the program is awarded by the amount of posts, views, and comments they receive on their posts in the previous quarter. Each quarter, we select the top 25 bloggers of influence and give them special access to products and services we have obtained through our network of partners. Here is how it works.  Each quarter we select the top 25 bloggers bases on the amount of posts that created in that quarter, and apply points to the views and comments those posts receive.  The selection is purely off of the numbers, we do not select any based on any other basis.  In fact in the first round, several of our key bloggers did not qualify in the top 25.  Though they are still loved dearly, we wanted a program that anyone could be a part of if they put in the hard work. This said, the first quarter ends at the end of March and we will have another round of influencers joining us.  Keep the posts rolling and maybe you will be selected as an influencer! Visit the influencers page to see who has the greatest influence on Geekswithblogs right now.   Technorati Tags: Geekswithblogs

• Does Agile force developers to work more?

  - by Shooshpanchick

  Looking at common Agile practices it seems to me that they (intentionally or unintentionally?) force developer to spend more time actually working as opposed to reading blogs/articles, chatting, coffee breaks and just plain procrastinating. In particular: 1) Pair programming - the biggest work-forcer, just because it is inconvenient to do all that procrastination when there are two of you sitting together. 2) Short stories - when you have a HUGE chunk of work that must be done in e.g. a month, it is pretty common to slack off in the first three weeks and switch to OMG DEADLINE mode for the last one. And with the little chunks (that must be done in a day or less) it is exact opposite - you feel that time is tight, there is no space for maneuvering, and you will be held accountable for the task pretty soon, so you start working immediately. 3) Team communication and cohesion - when you underperform in a slow, distanced and silent environment it may feel ok, but when at the end of the day at Scrum meeting everyone boasts what they have accomplished and you have nothing to say you may actually feel ashamed. 4) Testing and feedback - again, it prevents you from keeping tasks "99% ready" (when it's actually around 20%) until the deadline suddenly happens. Do you feel that under Agile you work more than under "conventional" methodologies? Is this pressure compensated by the more comfortable environment and by the feeling of actually getting right things done quickly?

• Office arangement - comfort vs. teamwork?

  - by finrod

  Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

• Distributed Rendering in the UDK and Unity

  - by N0xus

  At the moment I'm looking at getting a game engine to run in a CAVE environment. So far, during my research I've seen a lot of people being able to get both Unity and the Unreal engine up and running in a CAVE (someone did get CryEngine to work in one, but there is little research data about it). As of yet, I have not cemented my final choice of engine for use in the next stage of my project. I've experience in both, so the learning curve will be gentle on both. And both of the engines offer stereoscopic rendering, either already inbuilt with ReadD (Unreal) or by doing it yourself (Unity). Both can also make use of other input devices as well, such as the kinect or other devices. So again, both engines are still on the table. For the last bit of my preliminary research, I was advised to see if either, or both engines could do distributed rendering. I was advised this, as the final game we make could go into a variety of differently sized CAVEs. The one I have access to is roughly 2.4m x 3m cubed, and have been duly informed that this one is a "baby" compared to others. So, finally onto my question: Can either the Unreal Engine, or Unity Engine make it possible for developers to allow distributed rendering? Either through in built devices, or by creating my own plugin / script?

• How to really master ASP.NET MVC?

  - by user1620696

  Some years ago I've worked with web development just using PHP without focus on object orientation and so on. When I knew a little bit about it, and the benefits it brings, I've started moving to ASP.NET MVC. First, I've studied C# in the book Visual C# Step by Step. I've found it a good book for a beginner, and I could learn a lot of this new language with it. Now, when I've came to study ASP.NET MVC, I hadn't so much luck. I've studied on some books that explained MVC well and so on, but then started just saying: "do that, and now that, and then that", and I feel I couldn't really master ASP.NET MVC. I feel this, because when I was reading, I knew how to do the things the book taught, like implementing DI with Ninject and so on, but some time later, without looking at it for some time, I couldn't do it by myself. What I'm trying to say, is that usually I don't know where to start, how to do things in this framework and so on. How can I really master ASP.NET MVC? There is some book, some tutorial series, anything, that can really help with that? I'm pretty happy with the .NET framework, my problem isn't it, my only problem is working with the MVC framework, and applying the techniques from object orientation there. I don't know if this question is on-topic here, but I'm really just looking for some good references, to become better with this framework.

• How do I give Ubuntu 10.10 more space (when installed inside Windows 7 (via wubi))?

  - by Pavitar

  I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7. EDIT1: I used Wubi for the same. I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition. At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification. I have surfed through a lot of similar questions but this is not a duplicate. Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk? Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function. EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

• How to write a blog for SEO purpose

  - by Mathieu Imbert

  I have a photo sharing website, which provides very little textual content. Users can add tags to photos and a description, but it creates a lot of duplicate content, because most of the descriptions will be 'wow', 'lol', ... I don't think I should rely on users to build my SEO. I think it would be a great idea to write a blog, and use it to describe the best photos, start contests, explain themes, in short: create original content that search engines will love. Our website's main URL is like www.domain.com, and our new blog is hosted on blog.domain.com. From a SEO perspective, is it a good idea to keep the blog separate from the main site? This has the advantage to leave the original site unchanged, but will it add any page rank to the www.domain.com? If the blog ranks well it will obviously pass some page rank to the original through links. What do you think is the best option from a SEO perspective? Include the blog in www.domain.com? Or leave it in blog.domain.com?

• How to analyze data

  - by Subhash Dike

  We are working on an application that allows user to search/read some content in a particular domain. We wanted to add some capability in the app which can suggest user some content based on the usage pattern (analyze data based on frequency and relevance). Currently every time user search or read something we do store that information in backend database. We would like to use this data to present some additional content to user. Could someone explain what kind of tools will be required for such a job and any example? And what this concept is called, data analysis? data mining? business intelligence? or something else? Update: Sorry for being too broad, here is an example SQL Database (Just to give an idea, actual db is little different with normalization and stuff) Table: UserArticles Fields: UserName | ArticleId | ArticleTitle | DateVisited | ArticleCategory Table: CategoryArticles Fields: Category | Article Title | Author etc. One Category may have one more articles. One user may have read the same article multiple times (in this case we place additional entry in the user article table. Task: Use the information availabel in UserArticle table and rank categories in order which would be presented to user automatically in other part of application. Factors to be considered are frequency and recency. This might be possible through simple queries or may require specialized tools. Either way, the task is what mention above. I am not too sure which route to take, hence the question. Thoughts??

  What is a reasonable goal in terms of traffic for my Flex 3 site: www.brainpinata.com Since I began a couple of months ago, I've gotten roughly 5500 ad views and 280 ad clicks. And the ad revenue is a whopping $4.80. (I don't use Google Adsense). I advertise my site using Google Adwords to try to build traffic. My budget is $10/day. What should I do? a) Push the marketing. Add a blog. Try to get backlinks, contact blogs, start a Facebook page, tweet, etc. b) Google is only indexing the static content in the SWF. The questions/answers are pulled from a mySQL database. So, Google doesn't index 99% of the content. Should I re-do the site in HTML/Javascript and hard-code the questions for each puzzle? (This would be a challenge as I don't know javascript worth squat.) Or should I hard-code the questions in XML and put them in the Flex app? If I put the questions in an XML file it's roughly 500 KB. Other ideas? c) Should I switch ad networks? (I currently get about 100 visitors a day). My ad network pays so little that if I were to make even $500/month, I would need 550,000 ad views/month, which seems impossible. If I go ahead and switch ad networks, I need to find one that allows iFrames as I've got a Flex website. Which ad networks permit their ads to be shown in iFrames? d) Should I cut and run? I put a lot of work into this project and it would really stink to get nothing out of it. I'm looking for some good advice. Looking forward to your suggestions. Thank you. -Laxmidi

• What kind of language will replace C++ as C++ replaced C ? [closed]

  - by jokoon

  I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.

• PowerShell a constant in a changing world

  - by Rob Addis

  I've been programming for about 20 years now some of my friends have been at it for over 30. I have read many, many manuals and yes it's not my favourite past time. So 10 years ago I made a promise to myself to try and only learn about products which have long life times. I immediately gave up programming GUIs and concentrated on back end development as I decided that these products (Oracle, MQ Series, SQL Server, BizTalk and later WCF, WF) have longer life times and smaller incremental changes than front end products.10 years ago I had no idea how good a decision that would turn out to be. There have been so many different Microsoft products for the front end in that time; multiple versions of Windows Forms, FrontPage, Html, Javascript, ASP.net, Silverlight, SharePoint, WPF and now hopefully a stayer Metro.I remember being at a Microsoft conference in 2006 when Martin Fowler told a crowd of developers (I'm paraphrasing) "If you don't like change then you're in the wrong business!". Well I've been in the business for 20 years and yes I'm a little resistant to change. I like my investment in reading manuals and getting certified to be time well spent!Over the last 2 years I have been writing A LOT of PowerShell script, I think there is a good chance this product will still be around and be used for new development in 10 years, learning it is a good investment.
