  • Mod Rewrite - directing HTTP/HTTPS traffic to the appropriate virtual hosts

    - by kce
    I have an Apache2 web server (v. 2.2.16) running on Debian hosting three virtual hosts. The first two hosts are HTTP only (server1 and server2). The last host is HTTPS only (server3). My virtual host configuration files can be found at pastebin. I would like to use mod rewrite to get the following behavior: Any request for http://server3 is re-directed to https://server3 Any request for either https://server1 or https://server2 is re-directed to http://server1 or http://server2 as appropriate. Currently, requesting http://server3 gives you a 403 because indexing is disabled for that host and a request for https://server1 or https://server2 will resolve as https://server3 (as its the only virtual host running SSL). This behavior is not desirable. So far I have added a rewrite rule to the central configuration file (myServerWideConfs.conf), with unfortunately no effect. I was under the impression that this rule (or something similar) should rewrite all https:// requests for server1 and server2 to the proper http:// request. RewriteEngine On RewriteCond %{HTTP_HOST} !^server3 [NC] RewriteRule (.*) http://%{HTTP_HOST} My question is two-fold: What mod rewrite rules should I use to accomplish this? And where should they go? Debian's packaging of Apache has a pretty granular (i.e., fractured) configuration file layout; should my rewrite rules go in /etc/apache2/apache2.conf, /etc/apache2/conf.d/myServerWideConfs.conf, or the individual virtual host files? Is mod rewrite the right tool to accomplish this or am I missing something in my greater apache configuration?

  • Sprite and Physics components or sub-components?

    - by ashes999
    I'm taking my first dive into creating a very simple entity framework. The key concepts (classes) are: Entity (has 0+ components, can return components by type) SpriteEntity (everything you need to draw on screen, including lighting info) PhysicsEntity (velocity, acceleration, collision detection) I started out with physics notions in my sprite component, and then later removed them to a sub-component. The separation of concerns makes sense; a sprite is enough information to draw anything (X, Y, width, height, lighting, etc.) and physics piggybacks (uses the parent sprite to get X/Y/W/H) while adding physics notions of velocity and collisions. The problem is that I would like collisions to be on an entity level -- meaning "no matter what your representation is (be it sprites, text, or something else), collide against this entity." So I refactored and redirected collision handling from entities to sprite.physics, while mapping and returning the right entity on physics collisions. The problem is that writing code like this.GetComponent<SpriteComponent>().physics is a violation of abstraction. Which made me think (this is the TLDR): should I keep physics as a separate component from sprites, or a sub-component, or something else? How should I share data and separate concerns?

  • Should I swap from WCF to NserviceBus

    - by Matt Roberts
    We have a central server that sends and recieves messages from a number of PCs that are located on client networks in various locations. To facilitate this, currently I'm using WCF with TCPNetBindings, using duplex communication secured with certificates. Now, we have a number of issues with this - mainly that we are being asked to support "disconnected mode" (we need to be fault tolerant). From what I know, there is no simple way to do this using the WCF stack - we'd need to implement something and perhaps use msmq. I've been looking at NServiceBus lately, and from I can see it seems to fit the bill well - fault tolerance, messages can be sent over the internet via a simple http gateway, etc. I know it's well respected in the community, and I can see why from looking into it. So, my question is...Does employing NServiceBus sound like a sensible idea, or does anyone have any other suggestions / real world experience that relate to this? I guess I'm worried of introducing a new tech that I know relatively little about, and facing problems with things like securing it, setting everything up in a reliable way, gotchas along the way.. I'm also wary of "gold-plating" the architecture, and choosing something shiny that will end up bogging me down in implementation versus sticking with WCF and just making it work for me.. Thanks!

  • Trouble installing Rabbit VCS for nautilus

    - by Ranhiru Cooray
    I am using Ubuntu 11.10 and following instructions mentioned here to install Rabbit VCS. I added the PPA properly, did a sudo apt-get update and ran sudo apt-get install rabbitvcs-core rabbitvcs-nautilus rabbitvcs-thunar rabbitvcs-gedit rabbitvcs-cli There were dependency issues and I googled a bit and found out that I need to install RabbitVCS only for nautilus as that is the default file manager for Ubuntu. So I ran the install commands separately for rabbitvcs-core, rabbitvcs-gedit and rabbitvcs-cli. Now my understanding is that those are installed properly. However when I run the install command for rabbitvcs-nautilus, I still get a dependency issue. ranhiru@ranhiru-HP-HDX16-NoteBook-PC:~$ sudo apt-get install rabbitvcs-nautilus Reading package lists...

  • SQLAuthority News – Resolution for New Year 2011

    - by pinaldave
    Today is the first day of the year so I want to write something very light. Last Year: 2010 Last Year was a blast; really traveled a lot. My family and I went on vacation. There I enjoyed being father, rolling on the floor and playing with my daughter. Here is the list of the countries I visited throughout 2010: Singapore (twice) Malaysia (twice) Sri Lanka (thrice) Nepal (once) United States of America (twice) United Arab Emirates (UAE) (once) My daughter who just completed 1 year on September 1, 2010 has so far visited three countries: Singapore, Malaysia and Sri Lanka, where I have done lots of community activities. The list containing all my activities can be found at Pinal Dave’s Community Events. I have written nearly 380 blog posts last year. It would be difficult for me to pick a few. However, I keep a running list of all of my articles over here: All Articles on SQLAuthority.com. I have so far received more than 10,000 email questions during the year and consequently I have done my best to answer most of them. I strongly believe if one would Search SQLAuthority.com blog, they would have found the answer quickly. The best part of 2010 for me was working on SQL Server Health Check and SQL Server Performance Tuning. This Year: 2011 This year, I came up with two simple goals: 1. Personal Goal: Reduce Weight 2. Professional Goal: Stay busy for the entire year with SQL Server Performance Tuning Projects. (Currently January 2011 is booked with performance tuning projects and 40 other days are already booked throughout the year). Future The future is something one cannot exactly guess and one cannot see. I just want to wish all of you the very best for this coming New Year.

  • Annotate source code with diagrams as comments

    - by Steven Lu
    I write a lot of (primarily c++ and javascript) code that touches upon computational geometry and graphics and those kinds of topics, so I have found that visual diagrams have been an indispensable part of the process of solving problems. I have determined just now that "oh, wouldn't it just be fantastic if I could somehow attach a hand-drawn diagram to a piece of code as a comment", and this would allow me to come back to something I worked on, days, weeks, months earlier and far more quickly re-grok my algorithms. As a visual learner, I feel like this has the potential to improve my productivity with almost every type of programming because simple diagrams can help with understanding and reasoning about any type of non-trivial data structure. Graphs for example. During graph theory class at university I had only ever been able to truly comprehend the graph relationships that I could actually draw diagrammatical representations of. So... No IDE to my knowledge lets you save a picture as a comment to code. My thinking was that I or someone else could come up with some reasonably easy-to-use tool that can convert an image into a base64 binary string which I can then insert into my code. If the conversion/insertion process can be streamlined enough it would allow a far better connection between the diagram and the actual code, so I no longer need to chronographically search through my notebooks. Even more awesome: plugins for the IDEs to automatically parse out and display the image. There is absolutely nothing difficult about this from a theoretical point of view. My guess is that it would take some extra time for me to actually figure out how to extend my favorite IDEs and maintain these plugins, so I'd be totally happy with a sort of code post-processor which would do the same parsing out and rendering of the images and show them side by side with the code, inside of a browser or something. Since I'm a javascript programmer by trade. What do people think? Would anyone pay for this? I would.

  • How to Skip the Start Screen and Boot to the Desktop in Windows 8.1

    - by Mark Wilson
    For almost everyone who made the upgrade, Windows 8 proved to be something of a disappointment for one reason or another. Windows 8.1 (or Windows Blue) was released to address many of the issues users had complained about including reintroducing the ability to boot straight to the desktop. Being able to boot to the desktop rather than the Start screen is something that people have been clammering for ever since the first preview versions of Windows 8 were unveiled. There have been various third-party tools released as numerous workarounds used to get around the problem, but now it is an option that is built directly into the operating system. You’ll need to have downloaded and installed the update in order to proceed, but once you have done this, things are very simple. When you have Windows up and running after the upgrade, right click an empty section of the taskbar and select properties to bring up the newly named “Taskbar and Navigation properties” dialog.  Move to the Navigation tab and look in the “Start screen” section in the lower half of the dialog. Check the box labelled ‘Go to the desktop instead of Start when I sign in” and click OK.

  • Why use try … finally without a catch clause?

    - by Nick Rosencrantz
    The classical way to program is with try / catch but when is it appropriate to use try without catch? In Python the following appears legal and can make sense: try: #do work finally: #do something unconditional But we didn't catch anything. Similarly one could think in Java it would be try { //for example try to get a database connection } finally { //closeConnection(connection) } It looks good and suddenly I don't have to worry about exception types etc. But if this is good practice, when is it good practice? Or reasons why this is not good practice or not legal (I didn't compile the source I'm asking about and it could be a syntax error for Java but I checked that the Python surely compiles.) A related problem I've run into is that I continue writing the function / method and at the end I must return something and I'm in a place which should not be reached and it must be a return point so even if I handle the exceptions above I'm still returning null or an empty string at some point in the code which should not be reached, often the end of the method / function. I've always managed to restructure to code so that I don't have to return null since that absolutely appears to look like less than good practice.

  • Synaptic won't launch from menu in panel in fresh Lubuntu minimal desktop 12.04 install

    - by ven42
    I performed a fresh install of Lubuntu 12.04 with minimal desktop, as described here: https://help.ubuntu.com/community/Lubuntu/Documentation/MinimalInstall. To clarify, I did a command-line install from the Lubuntu alternative install disc, then I did an "apt-get install --no-install-recommends lubuntu-desktop". Everything is working fine, except that Synaptic will not run from the menu entry in the panel. I am not prompted for a password, and no window of any sort appears after clicking the menu entry. I installed lxshortcut to see what the shortcut was running, and the command is "synaptic-pkexec". If I type this command into the "Run" menu, I get the same behavior (or lack thereof). I can get Synaptic to open up just fine by typing "gksudo synaptic" at the "Run" menu. Also, if I run "synaptic-pkexec" from the terminal, then I am prompted for my password within the terminal, and after that Synaptic opens normally. Can someone please suggest the right way to get Synaptic working? I could just change the menu entry to "gksudo synaptic", but I'm guessing that it's set to "synaptic-pkexec" for a reason. I have a vague understanding that this pkexec business has something to do with PolicyKit, but I don't really know what PolicyKit is or how to tell if something is broken with it. Thanks.

  • Running & Managing Concurrent Queries in SQL Developer

    - by thatjeffsmith
    We’ve all been there – you’ve managed to write a query that takes longer than a few seconds to execute. Tuning aside, sometimes it takes longer than you want for a query to run. So what’s a SQL Developer user to do? I say, keep going! While you’re waiting for your query to finish, there’s no reason why you can’t continue on with your work. If you need to execute something else in a worksheet, there’s no reason to launch a 2nd or 3rd copy of SQL Developer. Just open an un-shared worksheet. Now while you’ve got 1 or more queries running, you can easily get yourself into a situation where you’re not sure what’s running where. Or maybe you want to cancel a query or just check how long something’s been running. Just open the Task Progress Panel If a query or task in SQL Developer takes more than 3-5 seconds, it will appear in the Task Progress panel. You can then watch the throbbers go back and forth while you sip your coffee/soda/Red Bull. Run a query, spawn a new worksheet, run another query, watch them in the Task Progress panel. Kudos and thanks to @leight0nn for helping me get the title of this post right If you’re looking for help in managing and monitoring sessions in general, check out this post.

  • How Do Nautilus Album Art Thumbnails work?

    - by Amir Adar
    There's something for which I've been searching an answer for a while now, but to no avail, and it's strange to me, as it seems like a thing that people would talk about: one of those nice little nonsense that enhance the computing experience a little bit. Anyway. I have a fair music collection. I save all the songs as ogg files. All is fine, and I can listen to the files, but there's something weird with the files in Nautilus: some have icons displaying their album art, while others don't, and I just can't understand WHY. I read on this site today that it's a matter of embedding the album art to the file, but that's not true, as I embedded the album art to the files I wanted several times, to no avail. Furthermore, removing an embedded album art from a file didn't have any effect on those that ARE displaying the icons. So my question is: How does it work? Where does Nautilus (or Ubuntu, I don't know) get the picture from? How do I edit it? Thanks in advance! -Amir

  • What do you call an obfuscator that isn't an obfuscator?

    - by Alex.Davies
    SmartAssembly, formerly {smartassembly}, version 5 is now available as an Early Access Build. You can get it here: http://www.red-gate.com/MessageBoard/viewforum.php?f=116 We're having second thoughts about the name change though. It isn't that we like the curly brackets, far from it. The trouble is that the first rule of product naming is to name a product by what it does. SmartAssembly may make an assembly smarter, but that's not something people really google for. The trouble is, I can't think of a better name for it. That's because SmartAssembly really does two completely separate things: Obfuscates Sets up your assembly for the awesome exception reports which get sent to you whenever your application crashes. You may have been (un?)lucky enough to see one in reflector if you use it. This is what those exception reports look like when they arrive back with the developer: Look at all those local variables! If you ask me, this is much cooler than the obfuscation. So obviously we don't want to call it just "Red Gate Obfuscator" or something, because it doesn't do justice to the exception reporting. What would you call it?

  • create a simple game board android

    - by user2819446
    I am a beginner in Android and I want to create a very simple 2D game. I've already programmed a Tic-Tac-Toe game. The drawing of the game board and connecting it with my game and input logic was quite difficult (as it was done separately, canvas drawing, calculating positions, etc). By now I figured out that there must be a simpler way. All I want is a simple grid; something like this: http://www.blelb.com/deutsch/blelbspots/spot29/images/hermannneg.gif. The edges should be visible and black, and each cell editable, containing either an image or nothing, so I can detect if the player is on that cell or not, move it... Think of it as Chess or something similar. Searching the internet during the last days, I am a bit overwhelmed of all the different options. After all, I think Gridview or Gridlayout is what I am searching for, but I'm still stuck. I hope you can help me with some good advice or maybe a link to a nice tutorial. I have checked several already, and none were exactly what I was searching for.

  • DNS and VPN issues

    - by Lewis
    I recently purchased a year contract for a KVM 512MB VPS running Ubuntu 11.04. I'm having some issues setting up some things on it though - two in particular that I just can't for the life of me figure out. Okay, so I'm trying to setup pptpd as my VPN for my iPhone and my Mac when I'm out on wireless networks. I'm able to login and the chap authenticates but that's as far as I get, no domains will resolve and end up loading forever, I uncommented ms-dns lines as someone had recommended to me and changed the DNS servers to Googles public ones with no luck, is there something I'm missing? (It's probably staring me in the face.) My second issue is that I have managed to setup LAMP but am having a problem with my domain, I have pointed the DNS at 123-reg to my VPS's IP and the 'www .' resolves properly, but when I try to go to the domain without the 'www .' I get the apache landing page ("The web server software is running but no content has been added, yet.") I'm pretty sure there's something I've gotta configure in Apache for the virtual host but I'm missing it. Apart from these minor set-backs I'm enjoying the low-level configuration options of having a VPS and love managing my own server. Thanks!

  • ubuntu one syncronizing problems

    - by user72249
    I am a user of Ubuntu and Ubuntu One. First: I had a serious problem with ubuntu one. I have a windows and several Ubuntu machine and they all sync one account. My first problem is that i can't really delete files. Whenever I delete something Ubu One resync it, so it appears again in my folder. Furthermore, when i move something to another dir it synconize the new location and resync the old one, so i got doubled my files. I can't reorganize my files. So i tried to delete the duplicated files through the web dash, but i cant reorder and select multiple files by extension. For example i wanted to move all PDF to another location... Second: I can't configure in the ubuntu one app the loacation of the main One folder. For example i want my One folder to be on another partition than my HOME folder. It is a main problem in linux and windows also. I tried to move that folder in windows with the hardlink method. So i uninstalled the U1, then i created a folder link to another drive, than installed the U1. THEN i lost all my files in my U1. Lucky thing that i have a backup, but i thought U1 is a stable solution for me, and i planned to extend my space, but these bugs are major problems! It's worth to pay for it if it's working perfectly. I think it's more important than releasing a new version in every month.

  • After force-installing a 32-bit deb failed, how can I install the 64-bit version?

    - by TryTryAgain
    I tried to dpkg -i --force-architecture google-earth-stable_i386.deb and it failed. But now when I try to install the amd64.deb it fails saying dpkg: error processing google-earth-stable_current_amd64.deb (--install): google-earth-stable: 6.2.2.6613-r0 (Multi-Arch: no) is not co-installable with google-earth-stable:i386 6.2.2.6613-r0 (Multi-Arch: no) which is currently installed Errors were encountered while processing: google-earth-stable_current_amd64.deb somehow it thinks the i386 version is installed. No google-earth files or directories even exist. sudo dpkg --configure -a outputs: dpkg: dependency problems prevent configuration of google-earth-stable:i386: google-earth-stable:i386 depends on lsb-core (= 3.2). dpkg: error processing google-earth-stable:i386 (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: google-earth-stable:i386 so it does exist in some capacity. sudo apt-get -f install does nothing out of the ordinary: Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded. The weird thing is that synaptic doesn't show any google earth package available let alone installed, nothing under the broken filter either. I have also tried sudo apt-get autoremove and sudo apt-get autoclean So, my question: How can I get rid of this issue?

  • The lifecycle of "cool"

    - by Dori
    I've been thinking lately about how some programming projects/products become "cool," and in particular, how that trend can later reverse. Here are two examples that might better explain my context: Textmate Whenever someone asks about text editors on OS X, the answer on the SE sites is an automatic "Textmate!" But looked at objectively: Textmate 1.0 shipped October 2004 Textmate 1.5 shipped January 2006 Textmate 2 was announced February 2006 As of September 2010, the currently shipping version is 1.5.9 In all of 2010, there have been a total of three posts on the Textmate blog At what point (if ever) do Textmate fans start thinking about switching to another text editor? When it breaks after some future Apple update? When alpha geeks they respect start recommending something else? Or? jQuery Whenever a JavaScript-related question is asked on the SE sites, the knee-jerk response is "jQuery!" I've seen it happen even when the question itself only required a single line of JavaScript. Or when the question could be better answered by using CSS. Do the answerers understand they're suggesting a blowtorch to light a candle? That they're recommending adding 70K or so of code to do something trivial? Or is it a symptom of "When you have a hammer, everything looks like a nail"—that is, jQuery is all they know how to do, so that's their recommendation? And do they understand that while they may know jQuery well, that doesn't necessarily mean that they know JavaScript? Is there a way to explain that learning JavaScript would make them better jQuery programmers? My bigger-picture questions: Is this niche focus primarily a trait of programmers? How do you get programmers to not immediately jump to recommending their personal favorites? What can motivate programmers to review their initial selection criteria and possibly modify their choice? Your thoughts?

  • What would you do to improve the working of a small Development team?

    - by Omar Kooheji
    My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

  • Tips for debugging Samba performance?

    - by j-g-faustus
    Samba gives me 24 MB/s read and 44 MB/s write, while ftp gives 97 and 112 MB/s under the same circumstances. The documentation says that Generally, you should find that Samba performs similarly to ftp at raw transfer speed. In my case it clearly doesn't. Where can I find tips on how to debug Samba performance? Or alternatively tips for replacing Samba with something else? (I can't use ftp, unfortunately, as I need something that can be used with rsync/rsnapshot.) More details: Both computers are running Ubuntu 10.10 (using Samba because I have a Mac as well) The Samba share is on a local home network, mounted as $ mount ... //server.local/share/ on /mnt/share type cifs (rw,mand) Samba performance was tested by copying (cp) a single file of ~4GB to and from the share, using time for timing and calculating transfer speed by hand. ftp performance are the numbers from the ftp client for get/put of the same file. iperf gives network speed ~900 Mbits/s bonnie++ gives disk speeds 200 MB/s on both sides for block reads as well as block writes Tried changing the parameters suggested in the performance tuning HOWTO (read/write raw, read size, socket options), most of them made little to no difference. (The one that made a difference caused write speed to drop 50%.)
