• XAMPP pointing a file outside root folder

  - by Ravi

  I am using XAMPP for first time in Mac. Running out problems accessing other than root folder(htdocs).when I am placing my web application inside htdocs with default httpd.conf file it works when I try to point my web application url in httpd.conf it throws error I am aware that to modify the root folder I need to do changes to my XAMPP/etc/httpd.conf file With Default XAMPP MAC Settings, I am trying to change Server root,Document root and Directory in XAMPP/etc/httpd.conf file the following ServerRoot "/Users/ravi/Documents/Development/Backbone/backboneboilerplate" DocumentRoot "/Users/ravi/Documents/Development/Backbone/backboneboilerplate" <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Deny from all </Directory> <Directory "/Users/ravi/Documents/Development/Backbone/backboneboilerplate"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> its throwing error when trying to start XAMPP httpd: Syntax error on line 54 of /Applications/XAMPP/xamppfiles/etc/httpd.conf: Cannot load /Users/ravi/Documents/Development/Backbone/backboneboilerplate/modules/mod_authn_file.so into server: cannot create object file image or add library

• Programming as a minor

  - by Tomas Cokis

  Hello Everyone! I've never asked a question here at programmers, and for reasons which will become obvious later I've never answered one here, but I do poke around in short bursts. Anyway, I'm 15 right now, and I've been programming in C++ for 4 years, just working on my own projects that are aim so high as to never be finished. I've been working on a single project for the last year, and every 3 months, I add a new system into it. It might be a value tabling directory enabled log system, or a render system, or a class to load up xml files, whatever it is, I don't mind too much that the overall project (a 3d engine) isn't ever going to get finished, I just get some satisfaction from getting what I have done building and running. I don't know what I want to do when I grow up, although I suspect I'll go into some form of engineering, but I was interested in knowing if I do choose to go into a career as a developer, what kind of material I could look at to push myself up and get myself experience that might help my career later. I'm not talking about books in particular, I'm more interested in subjects areas that will get me access to good job opportunities, or that will give me a hand-up if I do computer science and software related courses at uni. One of the things I was thinking of doing was designing some of the logic gate components of a small computer - which I started briefly over the holidays, working out integer addition, subtraction and multiplication. That kind of stuff interests me, but is it really useful - or more useful then just more programming? But anyway, Any advice? Should I continue on my perpetual 3d engine? Are there any other projects or particular accomplishments that would help my education? Perhaps I should mention that I live in Perth, Australia, so local software companies are likely to be more scarce then usual.

• Deploying war files in tomcat6

  - by user3215

  I am using tomcat5.5 for a long on ubuntu servers 8.10 and 9.10 and '/usr/share/tomcat/webapps/' is the path where I place my .war files and access them on the browser over network. On a sytem I've installed tomcat6 and I'm failing to find that where do I place my .war file of tomcat6's webapps. I checked deploying war under /var/lib/tomcat6/webapps/ and the war file is extracted and I think this should be the location but I could not access the page when I tried http://serverip:8080/myapp. I could access the default page properly when I navigate to http://serverip:8080. The same war file is working fine on tomcat servers which were not installed from apt repository.

• Strategy for restoring state via URL in web apps

  - by JW01

  This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

• Why does my DVD drive spin up every minute or so, spin down, and repeat (new Dell Studio 15 with Win

  - by cybergibbons

  We have just got a new Dell Studio 15 laptop running Windows 7 home premium with slot load DVD drive. If there is a DVD drive in the drive, every minute or so, the drive will spin up, make a couple of noises like it is reading something and then spin down. I think this is ruining battery life. There is no software running that is obviously accessing the drive. Any ideas to what it could be? Are there any tools I could use to try and identify the problem? Thanks.

• OS specific network delay, why?

  - by Atilla Filiz

  Since my new ISP installed their own router to my house(I rented a room in a student house so don't have much control on these), I started having strange delays. Any outgoing connection I do, be it http or ssh, is delayed for several seconds, and once it is established, I have no further problems. I open several simultaneous tabs in my browser and after about 5 to 8 seconds, they all connect and load simultaneously and quiet fast. I can actually play online games once I connect.What's more interesting is, I experience this only with Linux distros, namely Arch and some versions of Ubuntu. Access with Windows installs are quiet normal. What might be wrong with my router? Everything was fine with my old router but I have to use this one now.

• conky stopped displaying after daul monitors setup -- works when I detect monitors

  - by synaptik

  I just recently installed Ubuntu 12.04 on a clean install. I previously was using 11.10. I am also using a new laptop with a Dell docking-station and two external monitors. When I try to use the .conkyrc file that I used previously, my conky display simply doesn't show up anywhere. However, after I went to System Settings Displays and made some slight change that caused the monitors to refresh, then conky appeared as it should. Here is my .conkyrc file: background yes use_xft yes xftfont DejaVu Sans Mono:size=8 xftalpha 0.8 out_to_console no update_interval 2.0 total_run_times 0 draw_shades no short_units yes # Create own window instead of using desktop (required in nautilus) own_window yes # If own_window is yes, you may use type normal, desktop or override own_window_type override # Use pseudo transparency with own_window? own_window_transparent yes double_buffer yes default_color f0e68c color1 white color2 AD0303 alignment bottom_left gap_x 2 gap_y 30 no_buffers yes use_spacer right pad_percents 3 xftfont Terminus:size=10 TEXT $stippled_hr cpu1: ${color1}${cpu cpu1}% ${color} cpu2: ${color1}${cpu cpu2}% ${color} load: ${color1}$loadavg ${color} hot proc: ${color1}${top cpu 1}% - ${top name 1}${color} $stippled_hr big proc: ${color1}${top_mem mem_res 1} - ${top_mem name 1}${color} memory: ${color1}$mem/$memmax $memperc%${color} $stippled_hr disk: ${color1}${fs_used /}/${fs_size /}${color} swap: ${color1}${swap}/${swapmax}${color} ${diskiograph_read 15,120 color1 0077ff 750} ${diskiograph_write 15,120 color1 0077ff 750} $stippled_hr download: ${color1}${downspeed wlan0} /s${color} ${downspeedgraph eth0 20,120 104E8B 0077ff} upload: ${color1}${upspeed wlan0} /s${color} ${upspeedgraph eth0 20,120 104E8B 0077ff} How can I fix it so that I don't have to tamper with the Displays settings in order for conky to show up?

• Is the motherboard the cause of these errors?

  - by ianfuture

  Motherboard is : ASUS A7N8X-E Deluxe, Rev1.01, On start up get: "cmos checksum error - defaults loaded" error BIOS is reset everytime and can't boot to Windows off HDD. POST report is ok once I tell it there is no Floppy drive attached and not to seek it. The boot sequence starts then just as get to load windows safe mode options whole PC shuts down. BIOS is reset to defaults again. I've checked the battery and jumpers. Tried a known working battery. Changed Graphics card, changed memory, changed HD to one without an OS. Disconnected DVD drive. PSU is known to be ok. IN BIOS CPU is recognised correctly and memory is also recognised ok. So is it likely to be a bad motherboard or corrupted BIOS or something else? Thanks :)

• PHP: Extensionless URLs in IIS7 (windows)? (for wordpress)

  - by smithym

  Hi there, I have recently installed wordpress but i would like to configure extensionless URLs .. I am using IIS7 but on a shared server. I presume i cna add something to web.config file?? I am little bit confused, in IIS7 and asp.net mvc it is done via code... but in PHP i don't think it is .... so the only alternative is to use a re-write module but i can't as I am on a shared server and can't install ISAPI stuff.. so I was wondering if there is a way to do the mapping i.e. when going to testme it would actually load testme.php Any advise really appreciated Thanks

• Select tool to minimize JavaScript and CSS size

  - by Michael Freidgeim

  There are multiple ways and techniques how to combine and minify JS and CSS files.The good number of links can be found in http://stackoverflow.com/questions/882937/asp-net-script-and-css-compression and in http://www.hanselman.com/blog/TheImportanceAndEaseOfMinifyingYourCSSAndJavaScriptAndOptimizingPNGsForYourBlogOrWebsite.aspx There are 2 major approaches- do it during build or at run-time.In our application there are multiple user-controls, each of them required different JS or CSS files, and they loaded dynamically in the different combinations. We decided that loading all JS or CSS files for each page is not a good idea, but for each page we need to load different set of files.Based on this combining files on the build stage does not looks feasible.After Reviewing  different links I’ve decided that squishit should fit to our needs. http://www.codethinked.com/squishit-the-friendly-aspnet-javascript-and-css-squisherDifferent limitations of using SquishIt.We had some browser specific CSS files, that loaded conditionally depending of browser type(i.e IE and all other browsers). We had to put them in separate bundles,For Resources and AXD files we decide to use HttpModule and HttpHandler created by Mads KristensenTo GZIP html we are using wwWebUtils.GZipEncodePage() http://www.west-wind.com/weblog/posts/2007/Feb/05/More-on-GZip-compression-with-ASPNET-Content Just swap the order of which encoding you apply to start by asking for deflate support and then GZip afterwards.Additional tips about SquishIt.Use CDN: https://groups.google.com/group/squishit/browse_thread/thread/99f3b61444da9ad1Support intellisense and generate bundle in codebehind http://tech.kipusoep.nl/2010/07/23/umbraco-45-visual-studio-2010-dotless-jquery-vsdoc-squishit-masterpages/Links about other Libraries that were consideredA few links from http://stackoverflow.com/questions/5288656/which-one-has-better-minification-between-squishit-and-combres2.Net 4.5 will have out-of-the-box tools for JS/CSS combining.http://weblogs.asp.net/scottgu/archive/2011/11/27/new-bundling-and-minification-support-asp-net-4-5-series.aspx .

• How to fix bad Collada produced by FBX?

  - by David

  I tried to use the FBX SDK (2011.3.1) to load FBX files and save them as Collada files in order to be able to import FBX files in Panda3D. Unfortunately the resulting Collada files are not usable for several reasons, among them: There's a Maya specific extra technique diffuse <diffuse> <texture texture="Map__2-image" texcoord="CHANNEL0"> <extra> <technique profile="MAYA"> <wrapU sid="wrapU0">TRUE</wrapU> <wrapV sid="wrapV0">TRUE</wrapV> <blend_mode>ADD</blend_mode> </technique> </extra> </texture> </diffuse> It assigns a texcoord channel name that isn't referenced anywhere else in the file (in the previous code sample, no geometry uses "CHANNEL0"...) Every polygon is exported twice, a first time with a basic material (only diffuse color, specular color, etc.) and a second time with a textured material -- this doubles the number of polygons of each model without any valuable reason Anyway, the resulting Collada file cannot be opened correctly either with OpenCOLLADA or Panda3D's "dae2egg". Anyone has any experience on how to "fix" it and make it understandable by common and well-reputed Collada importers such as OpenCOLLADA?

• XAMPP - Unable to serve files larger than ~30MB [on hold]

  - by Sparx401

  I'm developing a site locally with XAMPP on Windows 7, and as far as media is concerned, I'm unable to play media files that are larger than 30MB or so. Both video and audio files (MP4 and MP3 respectively) generate this error in Chrome (and show similar errors in other browsers such as IE9 and Opera): No data received Unable to load the webpage because the server sent no data. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. It seems that the exact number of MB somewhat varies between browsers though. One video in question is 34MB and actually plays in Opera and IE9, but gives the aforementioned error in Chrome. I've checked to make sure the file paths were typed correctly and ensured that the directive for .htaccess is there to serve MP4s: AddType video/mp4 mp4 Also, I have these directives set as well in the same .htaccess file: php_value upload_max_filesize "80M" php_value post_max_size "80M" php_value max_input_time 60 php_value max_execution_time 60 And memory_limit is set in php.ini as "128M" so I'm left wondering: what is causing my files to not play, and what, if any, directives I have to change on the server-side? Perhaps something to do with limitations with the GET method (the method I'm seeing on Chrome's network tab among other header request/response info)?

• How low-power can a home server get?

  - by Halik

  I've got quite simple question actually. How green, low-power and efficient x86 home server can I build using consumer parts with rather constrained budget. After looking through some Google hits I've found out that system based on dual-core atom, some modest mITX board (gigabit lan, integrated audio and gfx etc), one RAM module and one 'green' WD HDD, powered by picoITX PSU uses about 30W at idle up to 40 at load. Can you get lower (or how much lower) then that? Maybe some VIA nano chips, or single core atom? My home server would take care of some back-upping mixed with little ftp/http traffic.

• Moving from windows to linux

  - by rincewind

  I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

• Why do you hate Java? Is it the language or the framework? [closed]

  - by zneak

  According to you all, Java is the third most-hated language here. The two other most hated languages are PHP and VBScript. (It's quite funny how they stand together on the podium.) I'd like to make it known that the question mostly addresses people who don't like Java. I assume here a number of subjective opinions as facts because they're usually considered true among people who don't like Java, and I don't want to be convinced otherwise here. If you're a Java enthusiast, you might find this question frustrating. It's never been made clear if people hate Java itself, or if they hate it because of the framework, or if it's a mixture of the two. On a side you have the language, where you have: the "everything should be an object" philosophy, even in instances where it should obviously be something else (event handlers I'm pointing you); checked exceptions; the idea that all logic should be presented as methods and properties is a big no-no; the fact that "closures" created by anonymous types only include final variables and arguments, but will allow write access to any member of the parent class; a few more. On the other side, you have the JDK, with... its load of inconsistencies and overengineering; monolithic class hierarchies; meaningless base exceptions like IOException (though other frameworks have similar exception hierarchies); sluggish responsiveness even with Swing; a few more. My question is, do you think that, if either one (Java or the JDK) was taken alone, and the other was dropped in favor of something else, the new combination would be better? For instance, if you could use the C# syntax with the JDK (adapting get*/set* methods into properties, and interfaces with only one method into delegates), or the Java syntax with the .NET Framework (doing the inverse transformations), would things get better in your opinion?

• Which dbghelp.dll do I use for debugging?

  - by Coldblackice

  I'm trying to configure symbols in Process Explorer. I have the Windows SDK installed (and thus, Debugging Tools). However, there are two versions of dbghelp.dll -- x86 and x64. Which one do I use? Other sources on the net say to just point to the dbghelp.dll that's in the base directory of the Debugging Tools. But there's no such dbghelp.dll -- they're in their respect 32 and 64 bit folders (i.e., C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x64). I'm using a Windows 7 x64 operating system, so does that mean I should load the x64 .dll? Or is it a matter of what I'm debugging? If it is a matter of what I'm debugging, does that mean that I have to switch this .dll depending what process I want to get symbol information on in Process Explorer?

• mod_jk fails to detect error state because JBoss gives 404, not 500

  - by Ilya Sher

  Configuration: Apache + mod_jk, several workers on other machines (load balancing). When JBoss fails to deploy an application for example because of failed connection to the database, requests to /myapp/somepage generate 404. How do I configure JBoss to return 500 for everything under /myapp when the application failed to deploy? Additional info: Since 404 is not an "error state" code, mod_jk does not mark the worker as failed and continues to route the traffic there. Since there might be valid requests to this application also generating 404, I can not configure mod_jk to treat 404 as an "error state"

• File saving disabled 'Saving has been disabled by system admin'

  - by Gubuntu

  I have coded my own html website recently, and today wished to add a Google calender object to it. I have not put this website on the web because it is for my own personal use and I can't buy a domain. So I just have a folder on my pc that I load the index.html from now and then. As I was saying, today I got an error while trying to save the Google calender object in. I am system admin on my PC, in fact no one else uses but me, except when I have friends round, but for once my PC seems to think I'm some standard account user, because I couldn't save. I thought of clicking close and seeing if it came up with save as, but it didn't, it said 'Are you sure you want to close without saving?' or something along the lines of that, and 'Saving has been disabled by your system admin.' I couldn't do anything. I tried looking at the settings of the file, and it had me as read only in one of the selections, so I changed that to read & write, but to no avail. I did not save as root when I last edited the file, so I don't get what's going on. Help! P.S. This is on Ask Ubuntu not Superuser because it is on my Ubuntu PC and it appears to be a problem with Ubuntu not root or hardware.

• How to teach Exception Handling for New Programmers?

  - by Kanini

  How do you go about teaching Exception Handling to Programmers. All other things are taught easily - Data Structures, ASP.NET, WinForms, WPF, WCF - you name it, everything can be taught easily. With Exception Handling, teaching them try-catch-finally is just the syntactic nature of Exception Handling. What should be taught however is - What part of your code do you put in the try block? What do you do in the catch block? Let me illustrate it with an example. You are working on a Windows Forms Project (a small utility) and you have designed it as below with 3 different projects. UILayer BusinessLayer DataLayer If an Exception (let us say of loading an XDocument throws an exception) is raised at DataLayer (the UILayer calls BusinessLayer which in turns calls the DataLayer), do you just do the following //In DataLayer try { XDocument xd_XmlDocument = XDocument.Load("systems.xml"); } catch(Exception ex) { throw ex; } which gets thrown again in the BusinessLayer and which is caught in UILayer where I write it to the log file? Is this how you go about Exception Handling?

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.
