• rewrite map (prg:) never finishes

  - by SooDesuNe

  using Apache and a prg type rewrite map. My map looks like: #!/usr/bin/perl $| = 1; # Turn off buffering while (<STDIN>) { print "someothersite.com"; } the rewrite rule declared in httpd.conf is: RewriteMap app_map prg:/file/path/test.pl RewriteRule (\/[\w]+)(\/[^\#\s]+)?$ http://${app_map:$1}$2 [P,L] And the log files show: init rewrite engine with requested uri /a/testlink.html applying pattern '(\/[\w]+)(\/[^\#\s]+)?$' to uri '/a/testlink.html' It appears like test.pl is never giving control back to apache, when the map is successfully found I expect to see this output in the log file: map lookup OK: map=app_map key=/a -> val=someothersite.com Why is my map not returning control back to apache?

• htaccess filesMatch exclusion

  - by Hikari

  I have the following directive in my htaccess <filesMatch "\.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml|html?)$"> FileETag None <ifModule mod_headers.c> Header unset ETag Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" </ifModule> </filesMatch> I copied that regex from someplace in Web months ago. It should add those headers to any HTTP Response that does NOT have those extensions. But it's not working, it's adding them to any Response. I also need to create another directive to add Header set Cache-Control "max-age=3600, public" to Responses of files that DOES have them. Could anybody help me make proper fileMatch regexes?

• How can I get non-programmer colleagues on board with bespoke software rather than Dynamics CRM + Sharepoint?

  - by Bendos

  I am working with a company which designs and builds one-off machines. They have been 'dabbling' with hosted Dynamics CRM and Sharepoint (on different servers!) in an attempt to centralise their data and help colleagues collaborate more effectively across projects. They haven't used either system to their potential. Now we are looking at the engineering department who already use a form of version control software for the various CAD files (Autodesk Vault) however it is becoming increasingly necessary to implement more of a generic file version control system as they use many more files than can be managed in Vault (sometimes just photos or scans of paper documents), hence why they were looking at using Sharepoint. However... as the 'programmer' of the bunch, I can see several scenarios which don't seem to fit well with the Dynamics + Sharepoint approach; simple reports based on cross-table queries, exporting certain metrics as a spreadsheet, defining project hierarchies and many-many relationships, and as such I have been pushing for an in-house developed 'ECM' / 'ERP' software package (perhaps in .NET or php). Some colleagues seem to attach a greater value to the MS software (perhaps becuase it has a logo!) but don't see that it's just a framework, not a solution. Can anyone provide a good example of when custom software would actually be better than using Dynamics + Sharepoint and how do I relate that to non-technical staff?

• Can anyone point me to some open source directX rendering engines or frameworks? [on hold]

  - by Jim

  I'm completely new to graphics API programmming, but not at all new to the theory and principle operation of game engines and rendering engines. That being said, I want to do some experiments of rendering very dense geometry scenes in a basic rendering engine or game engine. I don't need a lot of bells and whistles. What I need is enough control that I can implement my own scene graph algorithms and control the rendering pipeline very specifically. My ideal candidate engine would be either a rendering engine or game engine with a modular design that might be ready to go out of the box but would be simple enough in case I need to rip out some of the guts in the rendering management and implement my own. It's a tough call because I'm right at the level where it's almost better to go from scratch, but there's no sense in having to build every single basic thing such as heirarchical transforms, etc. I just want to work with rendering optimization to push dense geometry for maximum FPS. Does anyone have a suggestion for an engine or basic framework to use? I requested DirectX in my title because I figured it would likely be better supported and less likely for me to run into some obscure less-documented problem. But OpenGL might be acceptable if the recommended framework was definitely better than my other options. EDIT: I should add that I really want GPU tessellation support (part of adding to the density of geometry detail).

• Disable IPv6 on Debian VPS

  - by chris_l

  I have a Debian Lenny VPS, that's running virtualized by Parallels/Virtuozzo. Currently, the network interface doesn't have an IPv6 address - and that's good, because I don't have an ip6tables configuration. But I assume, that I could wake up one day, and ifconfig will show me an ipv6 address for the interface - because I have no control over the kernel or its modules - they're under the control of the hosting company. That would leave the server completely vulnerable to attacks from IPv6 addresses. What would be the best way to disable IPv6 (for the interface or maybe for the entire host)? Usually I would simply disable the kernel module, but that's not possible in this case.

• Is NTFS-3G safe for writing?

  - by katrmr

  These days, I have to use the NTFS-3G driver to write to an NTFS drive (which will later be used in Windows). But I still remember the olde times of Linux ntfs driver which clearly said in the docs: 'If you write to an ntfs volume, run our special program afterwards which will clean up the damage done.' So, I read through the man, the docs, the Tuxera site and Askubuntu and found no discussion of the write-safety of NTFS-3G. The only thing that was mentioned somewhere is that the driver doesn't support the NTFS journal. So, the question is, can I use NTFS-3G and be sure that I will later read what I have written to the files? Won't, for example, Windows find the journal entries missing and 'clean up' the data according to its own faulty understanding?

• Certain Keyboard shortcuts not working

  - by user968808

  I have the logitech k800 keyboard but can't seem to get certain shortcuts working. I change in the keyboard shortcut settings volume up and down and it actually takes the key assignment but does not take effect when trying to use. After trying for a while I also tried to create a custom shortcut after with the command amixer -q sset Master 10%- Finally I tried changing the command to touch a file to see if it is actually responding but nothing. How can it take the key as an assignment in the shortcut settings but not to actually respond when pressing it. FYI other keys work like mute, next track etc. There is just 3 keys shortcuts not currently working. Thanks

• Is there any Ubuntu translation indicator?

  - by Oyibo

  For more precision: I'm runnning Ubuntu 12.04 I'd like an indicator which shows up to the left of the date/volume/wifi icons If possible I'd like to be able to change the translation language The indicator could use internet based translators (google translate etc.) or have a complete library come with it so translations can be obtained offline. Relating to usability: I'd like to have it work in a way where you click on the indicator icon and you can start typing either directly or once a window has opened and it instantly shows the translation you need (with your target languages pre-set or determined in options).

• Windows 7 PATH not expanding

  - by trinithis

  I am using the following to create and edit environment variables for Windows 7. Control Panel\All Control Panel Items\System -> Advanced system settings -> Environment Variables Under System variables I have the following pertinant variables: PROG32=C:\Program Files (x86) REALDWG_SDK_DIR=%PROG32%\Autodesk\RealDWG 2011 Path=%REALDWG_SDK_DIR%;%PROG32%\Haskell\bin However, the following happens: C:\>echo %PROG32% C:\Program Files (x86) C:\>echo %Path% %REALDWG_SDK_DIR%;C:\Program Files (x86)\Haskell\bin Is it possible to have a chain of variables expand? If I rename Path to something else, I sometimes get the problem, and sometimes I don't.

• Is it possible to allow the User Account to access the 'Volumes' without asking the Administrator's password?

  - by Tom

  Am the administrator of my Ubuntu system. Recently I added a new user account. But when ever the user tries to access or open the 'Volumes'(Drives where movies, songs and other files are stored) it asks for the Administrator's password. I created the user account to my other family members and I don't want to tell them my password. So is it possible to allow them to access the Volumes without asking Administrator's password ? UPDATE : Ubuntu was installed alongside Windows in my system. I will provide a screenshot of the Volume details -

• The device is not ready

  - by hmloo

  When you retrieve the drive info using the DriveInfo class, if you don't use the IsReady property to test whether a drive is ready, it will throw error as "The device is not ready". so you must use IsReady property to determines if the drive is ready to be queried, written to, or read from. The following code example demonstrates querying information for all drives on current system. using System; using System.IO; class Test { public static void Main() { DriveInfo[] allDrives = DriveInfo.GetDrives(); foreach (DriveInfo d in allDrives) { Console.WriteLine("Drive {0}", d.Name); Console.WriteLine(" File type: {0}", d.DriveType); if (d.IsReady == true) { Console.WriteLine(" Volume label: {0}", d.VolumeLabel); Console.WriteLine(" File system: {0}", d.DriveFormat); Console.WriteLine( " Available space to current user:{0, 15} bytes", d.AvailableFreeSpace); Console.WriteLine( " Total available space: {0, 15} bytes", d.TotalFreeSpace); Console.WriteLine( " Total size of drive: {0, 15} bytes ", d.TotalSize); } } } }

• Enable [command] key to register as something other than just [ctrl]?

  - by gojomo

  I'm running 10.04LTS inside VMWare Fusion on a Mac. The [command] key (aka [windows] on many keyboards) is almost always behaving as if it was [ctrl], even though I done anything explicit to request that behavior. In fact, in SystemPreferencesKeyboardLayoutsOptionsAlt/Win key behavior, 'default' is chosen (rather than the 'Control is mapped to Win keys' option). However, choosing other options there do not seem to change the handling of [command], at least not as tested in the SystemPreferenceKeyboard Shortcuts app. (No matter what I've tried, [command]-x is always detected as [Ctrl]-x in that app.) I've tried: various options under SystemPreferencesKeyboardLayoutsOptionsAlt/Win key behavior toggling the VMWare Fusion Preferences KKeyboard & Mouse Key Mappings setup which claims to map '[command]' to '[windows]', and restarting the VM in each position the xmodmap lines suggested at https://help.ubuntu.com/community/MappingWindowsKey And yet, it's clear that all Ubuntu apps aren't merging [ctrl] and [command], because in 'Terminal', [shift]-[ctrl]-c will Copy, but [shift]-[command]-c will not. If the [command]/[windows] key was recognized as anything else ('Super', 'Meta', 'Hyper'? I don't care as long as it's not 'Control'), then I could achieve my real goal (which happens to be enabling CMD-based cut/copy/paste in PyCharm, while leaving CTRL-X/etc available for emacs-like bindings). I think any solution which manages to make [command]-x appear as something other than [ctrl]-x in PreferencesKeyboard Shortcuts will probably do the trick.

• Domain Specific Software Engineering (DSSE)

  Domain Specific Software Engineering (DSSE) believes that creating every application from nothing is not advantageous when existing systems can be leveraged to create the same application in less time and with less cost.  This belief is founded in the idea that forcing applications to recreate exiting functionality is unnecessary. Why would we build a better wheel when we already have four really good and proven wheels? DSSE suggest that we take an existing wheel and just modify it to fit an existing need of a system. This allows developers to leverage existing codebases so that more time and expense are focused on creating more usable functionality compared to just creating more functionality. As an example, how many functions do we need to create to send an email when one can be created and used by all other applications within the existing domain? Key Factors of DSSE Domain Technology Business A Domain in DSSE is used to control the problem space for a project. This control allows for applications to be developed within specific constrains that focus development is to a specific direction.Technology in DSSE offers a variety of technological solutions to be applied within a domain. Technology Examples: Tools Patterns Architectures & Styles Legacy Systems Business is the motivator for any originations to use DSSE in there software development process. Business reason to use DSSE: Minimize Costs Maximize market and Profits When these factors are used in combination additional factors and benefits can be found. Result of combining Key Factors of DSSE Domain + Business  = Corporate Core Competencies Domain expertise improved by market and business expertise Domain + Technology = Application Family Architectures All possible technological solutions to problems in a domain without any business constraints.  Business + Technology =  Domain independent infrastructure Tools and techniques for building systems  independent of all domains  Domain + Business + Technology = Domain-specific software engineering Applies technology to domain related goals in the context of business and market expertise

• HTTP resource bundling/streaming practice

  - by icelava

  Our SPA (plain HTML and Javascript) makes use of huge volume of javascript and other resources that are downloaded via XHR. Given the sheer number of components and browser simultaneous request limits, we're thinking for ways to deliver our resources in a more efficient manner. A method we're considering is bundling several resources that logically form a coherent group into a single file; thus reducing down to only one XHR (per group). Furthermore to make it more responsive, we'd like to constantly inspect the partial responseText during the LOADING state, determining if a usable chunk (atomic resource) has already been downloaded, and make it available for deserialization/processing even before the XHR is DONE. (a stream-like experience) We're thinking surely somebody else would've considered roughly the same approach before, but haven't really come across any library/framework or container file format that is suitable for our scenario. Anybody else know of something similar?

• Alternating links and slide down content on a list of sub sections

  - by user27291

  I have a page for a doctor's practice. In the summary page for the practice there is a list of subsections such as Women's, Men's, Children, Sport, etc. Some of these sub sections are very large, others can be a paragraph or more with a short unordered list. In terms of content volume, the large subsections warrant their own separate page, the smaller one's not so much. I created a little plugin which enables me to use the list of subsections in 2 ways. When clicking on the title of a larger section, you'll be sent through to it's own page. For the smaller sections, a slide down box will open with the information. Is this a good way to handle my information architecture? Should I be giving the smaller sub sections their own page for SEO purposes?

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.

• How to add entries to combobox in Word XP

• Role based access to resources for a RESTful service

  - by mutex

  I'm still wrapping my head around REST, but I wonder if someone can help with any suggestions or approaches to role based access control for a RESTful service, particularly from the point of view of securing the data and how the URLs might look. It's probably best to consider an example: Say I have a REST service for Customers, and want to split the users of this REST service into Admin, Editor and Reader roles: Admins can change all attributes of a Customer resource Editors can change only some Readers can only view them. Access control rights are assigned to the Customers entities individually. So for example a user of the service might have admin rights to Customers 1,2 and 3 but Editor access to 4,5 and Reader access to 7,8,9. Now consider the user calling the service. What is a good way to seperate the list of Customers for the current User? GET /Customer - this might get a list of all customers that the current user has Admin\Editor\Reader access to. But then on each Customer the consumer would need an indication of what role they have. Or would it be "better" having something like GET /Customer/Admin - return all customers the current user has Admin access to. Just looking for some high level pointers or reading on a decent way to secure\filter the resources based on roles of the current user.

• Windows 7: How to boot up in normal mode after improper shut down?

  - by Level1Coder

  I work in two different locations and whenever there is a power outage at one of the locations, Windows 7 detects that the system was improperly shutdown. Once the power is up, the PC powers on and Windows 7 enters REPAIR/SAFE mode where only someone physically in front of the PC can control it. (Networking is all disabled in this mode) Now before it enters REPAIR/SAFE mode, there is an option for a NORMAL boot. But the catch is that REPAIR/SAFE mode is selected by default with a 30 second timer. Once it automatically enters REPAIR/SAFE mode and if nobody is at the other location, I have no way to remote control it anymore. And then I have to drive over to the other location and reboot it and select boot into NORMAL mode. Where can I change this setting so that Windows 7 always boots into NORMAL mode no matter how many times it is improperly shut down?

• Are there any reliable solutions for annotations/reflection/code-metadata in C?

  - by dukeofgaming

  Not all languages support java-like annotations or C#-like attributes or code metadata in general, however that doesn't mean it is not possible to have in languages that don't have this. An example is PHP with Stubbles and the Doctrine annotation library. My question is, is there anything like this for C?, or are there any reliable ways of doing reflection with extended code metadata in C? Ideally, I'm looking for something that reads javadoc-like comments. Edit: The reason for me *needing* as opposed to just wanting, is that I need to generate C code and code-metadata from a database, as well as being able to edit that metadada and update the database. The volume of the work (~15,000 variables/structures/functions to generate from this database) justifies the solution.

• Hosting woes

  Unfortunately quite a few people have noticed our recent hosting problems, but if you are reading this they should all be over, so please accept our apologies. Our former web host decided migrate to a new platform, it had all sorts or great features, but on reflection hosting wasn’t one of them. We knew it was coming, and had even been proactive and requested several dates on their migration control panel so I could be around to check it afterwards. The dates came and went without anything happening, so we sat back and carried on on for a couple of months thinking they’d get back to us when they were ready. Then out of the blue I get an email saying it has happened! Now this is what I call timing, I had client work to complete, a 50 minute presentation to write and there was a little conference called SQLBits that I help organise at the end of the week, and then our hosting provider decides to migrate our sites. Unfortunately they only migrated parts of the sites, they forgot things like the database for SQLDTS. The database eventually appeared, but the data didn’t. Then the data pitched up but without the stored procedures. I was even asked if I could perform a backup and send it to them, as they were getting timeout errors. Never mind the issues of performing a native backup on a hosted server, whilst I could have done something, the question actually left me speechless. So you cannot access your own SQL server and you expect me to be able to help? This site was there, but hadn’t been set as an IIS application so all path references were wrong which meant no CSS and all the internal navigation and links were wrong. The new improved hosting platform Control Panel didn't appear to like setting applications. It said it would, you’d have to wait 2 hours of course, then just decided not to bother after all. So needless to say after a very successful SQLBits I focused my attention on finding a new web host, and here we are again. Sorry it took so long.

• Does programmable hardware exist to allow hardware to be programmed by computers?

  - by agentbanks217

  I am a programmer and I have never really dealt with the hardware of anything, only software. I want to start building things that I can control from my computer using programming. My question is are there such devices on the market that have a programmable interface or API? For example, I want to build a automated window blinds opening/closing device, and I would like to be able to control it from my computer e.g. writing an app or some code to schedule them when to open and close. I would like to know if there are any devices that can be programmed to do that (the computer part)? Thanks!
