• 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?

• Is chess-like AI really inapplicable in turn-based strategy games?

  - by Joh

  Obviously, trying to apply the min-max algorithm on the complete tree of moves works only for small games (I apologize to all chess enthusiasts, by "small" I do not mean "simplistic"). For typical turn-based strategy games where the board is often wider than 100 tiles and all pieces in a side can move simultaneously, the min-max algorithm is inapplicable. I was wondering if a partial min-max algorithm which limits itself to N board configurations at each depth couldn't be good enough? Using a genetic algorithm, it might be possible to find a number of board configurations that are good wrt to the evaluation function. Hopefully, these configurations might also be good wrt to long-term goals. I would be surprised if this hasn't been thought of before and tried. Has it? How does it work?

• Web technologies on GUI apps

  - by Apalala

  I developed many GUI applications for the Windows platform during my early professional career, and saw several GUI frameworks come, have whole magazines devoted to them, and then fade away. MFC is iconic. Tasked with writing yet another GUI application, I starter researching cross-platform frameworks like Qt and WxWindows. I found the same steep learning curves I knew from before, and tooling doesn't help much in building a functional and elegant user interface because its clumsy and complicated. But people are building beautiful and functional UIs on the Web all the time (look at this site!). The standards, the libraries, and the tools are certainly there. My thought and my question: Why not write a GUI in which most of the UI is handled by an embedded browser? I already know that the Qt widgets support a large part of CSS and JavaScript, and programmers with good knowledge about web development are relatively easy to find, ..., so... Have you done something like that before? What's your experience/advise?

• Where is a good spot to start when writing a LWJGL game engine?

  - by Alcionic

  I'm starting work on a huge game and somewhere along my train of thought I decided it would be a good idea to write my own engine for the game. I was originally going to use JMonkeyEngine but there were some things about it that just didn't work well with me. I wanted full control over every aspect of the entire process. Where would a good place to start be when writing your own engine? I have no experience with LWJGL but I learn quick. Either advice or some place where there is good advice would be nice. Thanks!

• What do I need to do, to get placed in any software company?

  - by Anto Aravinth

  I'm doing my 3rd year CSE Engineering. I guess this is the right time to ask this question! As in the next year, I'm going to do projects, "get my hands dirty". And there is only few days left out, as I know many people in Stack Overflow are working in Software field, I thought to ask these question. Does the project that I'm doing in my final year need to be excellent? If so, what kind of project to do? And how do you say that the project is excellent or not? Writing the code is very fun and serious at times. But the code should have a good algorithm? And mostly in any software companies interview, what kind of question they ask? Not but not the least, mastering in any particular language speaks in interviews?

• Silverlight Goes Mobile!

  - by PeterTweed

  The most exciting announcements from Mix 2010 last week for me were the release of the Windows Phone 7 Series SDK and the news that the platform utilizes Silverlight for the application development technology. From the press and exposure that the platform is being given and the experience that is promised it looks like the Windows Phone 7 Series could eventually compete with the iPhone. For me this is exciting as Silverlight can now be used to develop RIA apps, easily deployed desktop apps and mobile apps. As someone who delivers enterprise technology solutions this equates to a whole bunch of opportunity knocking at the door and asking to join the party. Watch this space for future posts on developing apps on the Windows Phone 7 Series platform!

• How does the "Fourth Dimension" work with arrays?

  - by Questionmark

  Abstract: So, as I understand it (although I have a very limited understanding), there are three dimensions that we (usually) work with physically: The 1st would be represented by a line. The 2nd would be represented by a square. The 3rd would be represented by a cube. Simple enough until we get to the 4th -- It is kinda hard to draw in a 3D space, if you know what I mean... Some people say that it has something to do with time. The Question: Now, that is all great with me. My question isn't about this, or I'd be asking it on MathSO or PhysicsSO. My question is: How does the computer handle this with arrays? I know that you can create 4D, 5D, 6D, etc... arrays in many different programming languages, but I want to know how that works.

• User eXperience

  - by Daniel Moth

  The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

• Directing from a 1und1 hosting solution, with urls intact

  - by Jelmar

  Hi, I have done this before on GoDaddy without a hitch, but I cannot seem to figure out this particular case. I have a domain space with temporary url http://yogainun.mysubname.com/ and am hosting the domain name that is to be applied to it at 1und1.de. Right now I have set it up so that from the 1und1 domain name hosting the address http://www.yoga-in-unternehmen.de/ is frame redirected to the subdomain that I just referred to. But this is not what I want. http://www.yoga-in-unternehmen.de/ is to be the domain. With the frame redirect, url's like http://www.yoga-in-unternehmen.de/example-article do not show up. But this is what I want. With godaddy in a similar case, I just turned on DNS and changed the name servers. That worked without problem, but with 1und1 not. Is there something I am missing?

• Yandex frequently replaces page names with ampersands

  - by Guy

  The Yandex spider is a frequent visitor to one of the sites I manage. On ocassion it replaces the page name with two ampersands and a space. So if the page is: /mypage.aspx?param=value then it will try and crawl it as: /&& ?param=value Any idea why it is doing this? [EDIT] If I remember correctly the IP that this "mistake" is coming from is based in California and not Russia. I believe that they crawl US sites from a US based IP address. Not sure if that helps. More Info about request: IP: 199.21.99.82 City: Palo Alto State: California Country: United States ISP: Yandex Inc. User-Agent: Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)

• ReportViewer configuration

  Some of my team member was facing configuring report viewer.Most of the post are confusing or not able to understand properly. This is what we concluded and thought to put a quick note on it. No 1 Section : This is the report name No 2 Section : ReportServer make the default name on URL sometime even if you don’t see on browser you still need to try with “Reportserver” on url. In our case the DB/report team did not mentioned nothing about “ReprtServer” on URL but it was needed. No 3. “Adventure Works...(read more)

• IIS 6 405 error when POSTing through I-Frame

  - by Angelo R.

  Before I begin, I must add that I am more of a programmer, so please be patient :p I have a 2003 server running IIS 6. I am trying to create a Facebook application that accesses a url on my server through an I-Frame. However, Facebook is trying to send some data via POST to my page. I assumed it wouldn't be a problem since the page is .html, but I keep receiving 405 errors (Incorrect Verbs) when trying to access it. Since these are generated by IIS, I had hoped there would be a way for me to allow html files to accept POST. However, after a lot of Googling, it seems like that isn't possible, so instead I figure I can convert the page to an aspx one, and that should work... however I am running in to the same issue. I thought that simply adding POST to the .aspx entry in Application Extension Mapping would work, but it still doesn't. Does anyone know what the problem could potentially be?

  - by Duy Nguyen

  Ubuntu 12.04 was functioning properly . Then after an update, some graphic elements stop working properly. I could not launch programs that has 3D elements. Work space switcher's window displays 2D window instead of a 3D like usual. In Details menu, the Graphic row is blank. I am using Intel GMA 4500MHD graphic card. I am guessing that the driver is not properly installed? Anyone has the same issue? Please help!

• How can I test if a point lies between two parallel lines?

  - by Harold

  In the game I'm designing there is a blast that shoots out from an origin point towards the direction of the mouse. The width of this blast is always going to be the same. Along the bottom of the screen (what's currently) squares move about which should be effected by the blast that the player controls. Currently I am trying to work out a way to discover if the corners of these squares are within the blast's two bounding lines. I thought the best way to do this would be to rotate the corners of the square around an origin point as if the blast were completely horizontal and see if the Y values of the corners were less than or equal to the width of the blast which would mean that they lie within the effected region, but I can't work out

• Page load speeds effect on crawl rate

  - by Sam Pegler

  We've noticed a big drop in the total pages crawled per day on our site, we have no control over the crawl rate in google webmaster tools so it's possible this has been changed by google. However it's a fairly large site and I wouldn't of thought that the crawl rate would've been decreased. What we have noticed though is a sizeable increase in page load times, in my mind this would be the cause. Can anyone else confirm if the crawl rate is directly correlated to page load time? Seems logical, longer page load time, less pages crawled. Any decent documentation on this would be appreciated, I don't normally have any input on SEO so this is new to me.

• How do I hire testers by giving them a buggy app for testing their efficiency?

  - by Jay

  My boss wants to recruit testers based on their testing efficiency (number of bugs identified). So, he's shortlisted 5 people and I need to give them an app full of bugs and see how they fare in reporting obvious bugs, and hidden bugs. I know.... it kind of sounds weird. I guess, this is just like the coding world, where you hire a programmer by assessing his/her programming ability (which is a little easier). Once hired, these testers would be testing a java swing app, so their familiarity of testing frameworks/tools is not really required. So, my question here is - How do I go about finding buggy apps (web/non-web), preferably java ones, that I can have the shortlisted testers have a go at? How would you go about this task if your boss asks you to do so? I am kind of clueless at this point - I googled a bit, thought about finding new apps on sourceforge with lots of bugs, but both approaches didn't work for me.

• ScreenManagement how do I had different controls?

  - by DiasFrancisco

  I saw a question here using DataTemplates with WPF for ScreenManagement, I was curious and I gave it a try I think the ideia is amazing and very clean. Though I'm new to WPF and I read a lot of times that almost everything should be made in XAML and very little should be "coded behind". My questions resolves about using the datatemplate ideia, WHERE should the code that calls the transitions be? where should I define which commands are avaiable in which screens. For example: [ScreenA] Commands: Pressing B - Goes to state B Pressing ESC - Exits [ScreenB] Commands: Pressing A - Goes to state A Pressing SPACE - Exits where do I define the keyEventHandlers? and where do I call the next screen? I'm doing this as an hobby for learning and "if you are learning, better learn it right" :) Thank you for your time.

• Finally found a replacement for my.live.com&hellip;

  - by eddraper

  As I had alluded to before, the transition of http://my.live.com/ to http://my.msn.com/ caused me serious grief. I've been an RSS addict for many, many years and I found the my.live.com UI to be the ultimate RSS reader and gateway to the web. It had been my home page for a long time.  My.msn has a LONG way to go before it matches the elegance and performance of my.live. The site I ended up going with is http://www.netvibes.com/ .   It’s the closest thing I could find that could do four column tiles with a reasonable amount of information density .  I’d still prefer a lot less “chrome” and better use of space, but it’s as close as I’m going to get… One feature I really do like about netvibes, is the pagination feature.  The built in feed reader is also quite nice… All-in-all, I’d recommend netvibes…

• Problem with the keyboard layout in Emacs (ubuntu 12.04)

  - by user61648

  I've got some problems with the keyboard layout. I have a french AZERTY keyboard. When I switch to another layout (I tested both programmer DVORAK and Greek) everything seems fine. However, in emacs, I have a more unexpected (at least for me) behavior. For example, in DVORAK, I thought to obtain: On my french Keyboard - DVORAK X - Q Alt-X - Alt-Q But I have: X - Q Alt-X - Alt-X When I press the Alt key, the layout change seems to be inactivated. I precise I didn't activated any shortcut containing the Alt key for the layout switching. Moreover, I'm not sure this behavior is restricted to Emacs, but I don't use shortcuts like Alt-... in another application. Is a such behavior normal ? And in this case, how can I use a shortcut like Alt-Q when I switch to DVORAK ?

• ssrs: the report execution has expired or cannot be found

  Today I got an exception in a report using SQL Server Reporting Services 2008 R2, but only when attempting to go to the last page of a large report: The report execution sgjahs45wg5vkmi05lq4zaee has expired or cannot be found.;Digging into the logs I found this:library!ReportServer_0-47!149c!12/06/2012-12:37:58:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerStorageException: , An error occurred within the report server database.  This may be due to a connection failure, timeout or low disk condition within the database.;I knew it wasn't a network problem or timeout because I could repeat the problem at will.  I checked the disk space and that seemed fine as well.  The real issue was a lack of memory on the database server that had the ReportServer database.  Restarting the SQL Server engine freed up plenty of RAM and the problem immediately went away.

• Designing an API on top with Java RMI and Rest APIs

  - by user1303881

  I'm working on the backend of a java web application. We have a document repository (Fedora Commons specifically) where we house xml files. I want to abstract the API of the repository internally so that we aren't tightly coupled to one product. I'd also like to give the flexibility of connecting to to a repository via Java RMI or REST APIs. I was hoping to get advice or resources on how to implement something like this. My thought it that I'd have some abstract repository class that had methods like getRecord, updateRecord, and deleteRecord. In the constructor I would pass the URI for the repository and the API method and port. This would allow some flexibility in the future so that if the REST api became more practical, but allow the flexibility or using RMI which could (should?) have better performance. Am I over thinking this or am I on the right path?
