• How can I create profiles for the windows that are open on my Mac?

  - by Kyle Hayes

  As a semi-dual monitor user on my MacBook, I run into a particular issue that drives me nuts. The scenario is at work I run my MacBook Pro's display as the secondary monitor to a dual-monitor setup. I primarily use the secondary view for my social network windows (Adium, Tweetie, Gabbble, and IRC). I position exactly as I want them to see all at the same time. However, when I disconnect my MBP to go home and reconnect to my other monitor at home, all the applications were shifted onto the main screen (since that is where they went when I disconnected the monitor before I left). With this, I have to go through the whole process again to move and position them on the secondary screen again. Is there a utility or application that will allow me to create screen/window profiles that will basically memorize the current position of all the windows and persist it to be re-instantiated later?

• sound clipping in windows 7 64bit

  - by Sonic Soul

  something is up with 64 bit version of windows 7. i have 2 (good pro-sumer) sound cards which i've used in other version of windows 7 w/out problems, but now it is causing severe clipping (noise, sound having little gaps surrounded by static).. the cards i am using is echo mia, and native instruments audio kontrol 1. the audio kontrol 1 is a external card, and would work ok for a few hours after rebooting, and than it would go back into clipping mode, to the point where you tube videos would not play from trying to process sound and it stopping for extended periods of time. echo mia is performing better, but there is still some clipping and distortion. the machine i use is newly built, with i7 920 64 bit cpu, 6 gigs of ram and an outdated nvidia video card (geforece 7950 gx2)

• Win2008 DC in a Windows 2000 domain: can I keep the old DC?

  - by gravyface

  Will be putting a new Windows 2008 SE Server into a single domain network with two domain controllers, both running Windows 2000 Server. The functional level of the domain is mixed mode/2000. Until a second 2008 DC can be purchased, I'd like to leave the current Win2k operational master DC as a backup DC as the other member servers running 2003 have either accounting/SQL or Exchange on them. Eventually all the w2k servers will be decommissioned, but until then, I need another DC for redundancy. Following the standard process for adding a new DC, can I leave the old operational master DC (or the other backup DC) running after I transfer the FSMO roles to the new server? Will this cause any issues?

• browser without gpu support

  - by manuzhang

  Google has an Easter egg that draws 3D graph but when I tried it out on chrome it complained about no WebGL support. I've also tested it on Firefox whose WebGL support was enabled but ended up with the same problem. Thus, I suspect it's an issue of my GPU. Some googling led me to chrome://gpu and here's what I got Graphics Feature Status Canvas: Software only, hardware acceleration unavailable HTML Rendering: Software only, hardware acceleration unavailable 3D CSS: Unavailable. Hardware acceleration unavailable WebGL: Unavailable. Hardware acceleration unavailable WebGL multisampling: Unavailable. Hardware acceleration unavailable Problems Detected GPU process was unable to boot. Access to GPU disallowed. GL driver is software rendered. Accelerated compositing is disabled.: 59302 Mesa drivers in linux older than 7.11 are assumed to be buggy. Accelerated 2d canvas is unstable in Linux at the moment.

• Standards Matter: The Battle For Interoperability Continues

  - by michael.rowell

  Great Article, although it is a little dated at this point. Information Week Article Standards Matter: The Battle for Interoperability goes on Summary If you're guilty of relegating standards support to a "nice to have" feature rather than a requirement, you're part of the problem. If you want products to interoperate, be prepared to walk away if a vendor can't prove compliance. Don't be brushed off with promises of standards support "on the road map." The alternative is vendor lock-in and higher costs, including the cost of maintaining systems that don't work together. Standards bodies are imperfect and must do better. The alternative: splintered networks and broken promises. The point: "The secret sauce to a successful 'working standard' isn't necessarily IETF or another longstanding body," says Jonathan Feldman, director of IT services for the city of Asheville, N.C., and an InformationWeek Analytics contributor. "Rather, an earnest and honest effort by a group that has governance outside of a single corporation's control is what's important." In order to have true interoperability vendors as well as customers must be actively engaged in the standards process. Vendors must be willing to truly work together and not be protecting an existing product. Customers must also be willing to truly to work together and not be demanding a solution that only meets their needs but instead meets the needs of all participants. Ultimately, customers must be willing to reward vendor compliance by requiring compliance in products and services that they purchase and deploy. Managers that deploy systems without compliance to standards are only hurting themselves. Standards do matter. When developed openly and deployed compliantly standards deliver interoperability which provides solid business value.

• Handy Tool for Code Cleanup: Automated Class Element Reordering

  - by Geertjan

  You're working on an application and this thought occurs to you: "Wouldn't it be cool if I could define rules specifying that all static members, initializers, and fields should always be at the top of the class? And then, whenever I wanted to, I'd start off a process that would actually do the reordering for me, moving class elements around, based on the rules I had defined, automatically, across one or more classes or packages or even complete code bases, all at the same time?" Well, here you go: That's where you can set rules for the ordering of your class members. A new hint (i.e., new in NetBeans IDE 7.3), which you need to enable yourself because by default it is disabled, let's the IDE show a hint in the Java Editor whenever there's code that isn't ordered according to the rules you defined: The first element in a file that the Java Editor identifies as not matching your rules gets a lightbulb hint shown in the left sidebar: Then, when you click the lightbulb, automatically the file is reordered according to your defined rules. However, it's not much fun going through each file individually to fix class elements as shown above. For that reason, you can go to "Refactor | Inspect and Transform". There, in the "Inspect and Transform" dialog, you can choose the hint shown above and then specify that you'd like it to be applied to a scope of your choice, which could be a file, a package, a project, combinations of these, or all of the open projects, as shown below: Then, when Inspect is clicked, the Refactoring window shows all the members that are ordered in ways that don't conform to your rules: Click "Do Refactoring" above and, in one fell swoop, all the class elements within the selected scope are ordered according to your rules.

• How to close all background processes in unix?

  - by Gabi Purcaru

  I have something like: cd project && python manage.py runserver & cd utilities && ./coffee_auto_compiler.py And I want both of them to close on Ctrl-C (or some other command). How can I accomplish that? EDIT: I tried using jobs -x kill and kill `jobs -p `, but it doesn't seem to kill what I need. Here is what I mean: moon 8119 0.0 0.0 7556 3008 pts/0 S 13:17 0:00 /bin/bash moon 8120 6.8 0.4 24568 18928 pts/0 S 13:17 0:00 python manage.py runserver jobs -p give me just process 8119, but I also need to close 8120, since it's the thing that the first command opened. If it helps, the commands are actually in a Makefile, and I want it to run two daemons at the same time (and somehow close them at the same time). And yes, I'm using ubuntu, with bash

• Bad archive mirror using PXE boot method

  - by user11566

  I'm trying to automatically install Ubuntu on a client PC by using the PXE BOOT method....my Objectives are below: I am following the steps given in this link installation using PXE BOOT the server will have a KICKSTART config file which contains the parameters for the OS installation and the files which are required for the OS installations. the client will have to detect this configuration along with the setup files and complete the installation without any input from the user. In my server I have installed DHCP3-server,Apache2 and TFTP to help me with the installation. I have nearly achieved my first objective, I am able to boot my client using the files stored in the server but during the installation stage it is asking me to CHOOSE A MIRROR OF UBUNTU ARCHIVE I gave the server's IP address and the path in the server where the files are located but then its giving me this error BAD ARCHIVE MIRROR So is it possible that instead of downloading all the files from the internet and storing them on my disk can I use the files which comes with the UBUNTU-CD, and how to store these files in what format (should I zip them) on the disk? secondly I am also generating the ks.cfg which I wanted to give to the client for automatic installation of the OS. So how should the configuration file be given to the installation process?

• Joomla 1.5 Media Manager sets incorrect file permissions when uploading

  - by Scott Mayfield

  Howdy all, I have a Joomla 1.5 installation running on Windows Server 2008, installed via the Web Platform Installer. When uploading images with the media manager (native uploader, not the flash bulk uploader), the files arrive on the server correctly, but are given incorrect permissions. Specifically, the IIS_IUSRS group is not given access to the file. I might be incorrect about what group/user is SUPPOSED to get access to the files, but so far, I've found that unless I give IIS_IUSRS access to the uploaded files, they won't appear on the site or in the media manager (appear as broken images). Once I give IIS_IUSRS permission to the files, they work fine. So far, all the research I've done has led me to linux specific fixes that involve either changing the umask on the server, or directly modifying the Joomla codebase to add an appropriate chmod command to the upload process, but I really don't want to modify Joomla directly. I have to believe there's a setting here somewhere that will do the job, either on the Joomla or Windows side of the equation. Any thoughts? Scott

• Should I Use PHP as FastCGI?

  - by Synetech inc.

  Hi, I am running an Apache webserver on my Windows machine. It is not generally a public server (most of the little bit of traffic comes from the machine itself, and most of the public traffic comes from crawlers). Basically, it is mostly just for use as a test-bed, development system. I have read about how running PHP as FastCGI is better (ie faster and more stable) than as an Apache module. However, I really don’t like the idea of multiple PHP.exe processes (I don’t like that Apache has two processes and I’m not even too thrilled with Chromium’s multi-process model). So I’m wondering if it would be worthwhile to change PHP to FastCGI for this scenario. If it is, how would I configure it? Pretty much all of the information I have seen has been either for non-Windows or for IIS. As I said, I’m running Windows+Apache. Thanks a lot.

• Cleaning your BizTalk Build Server

  Just a little note for myself this one.At one of my customers where it is still BizTalk 2006 one of the build servers is intermittently getting issues so I wanted to run a script periodically to clean things up a little.  The below script is an example of how you can stop cruise control and all of the biztalk services, then clean the biztalk databases and reset the backup process and then click everything off again.This should keep the server a little cleaner and reduce the number of builds that occasionally fail for adhoc environmental issues.REM Server Clean ScriptREM =================== REM This script is ran to move the build server back to a clean state echo Stop Cruise Controlnet stop CCService echo Stop IISiisreset /stop echo Stop BizTalk Servicesnet stop BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Stop SSOnet stop ENTSSO echo Stop SQL Job Agentnet stop SQLSERVERAGENT echo Clean Message Boxsqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_CleanupMsgbox"sqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_PurgeSubscriptions"  echo Clean Tracking Databasesqlcmd -E -d BizTalkDTADb -Q "Exec dtasp_CleanHMData" echo Reset TDDS Stream Statussqlcmd -E -d BizTalkDTADb -Q "Update TDDS_StreamStatus Set lastSeqNum = 0" echo Force Full Backupsqlcmd -E -d BizTalkMgmtDB -Q "Exec sp_ForceFullBackup" echo Clean Backup Directorydel E:\BtsBackups\*.* /q  echo Start SSOnet start ENTSSO echo Start SQL Job Agentnet start SQLSERVERAGENT echo Start BizTalk Servicesnet start BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Start IISiisreset /start echo Start Cruise Controlnet start CCService

• Copying photos from camera stalls - how to track down issue?

  - by Hamish Downer

  When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs). None of the programs at the top of the cpu list in top are related to copying photos. There is not much in the logs - from /var/log/syslog Dec 2 16:20:52 mishtop dbus[945]: [system] Activating service name='org.freedesktop.UDisks' (using servicehelper) Dec 2 16:20:52 mishtop dbus[945]: [system] Successfully activated service 'org.freedesktop.UDisks' Dec 2 16:21:24 mishtop kernel: [ 2297.180130] usb 2-2: new high-speed USB device number 4 using ehci_hcd Dec 2 16:21:24 mishtop kernel: [ 2297.314272] usb 2-2: New USB device found, idVendor=04a9, idProduct=3146 Dec 2 16:21:24 mishtop kernel: [ 2297.314278] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Dec 2 16:21:24 mishtop kernel: [ 2297.314283] usb 2-2: Product: Canon Digital Camera Dec 2 16:21:24 mishtop kernel: [ 2297.314287] usb 2-2: Manufacturer: Canon Inc.

• Wireless DHCP doesn't work until wired Ethernet plugged in

  - by MT_Head

  A client of mine has an Asus R1F tablet running Windows XP Tablet SP3. It has an Intel 3945ABG wireless card; wired Ethernet is a Realtek something-or-other. In the past few days, it's developed an odd problem: WiFi authenticates, but can't get an address via DHCP. plug in wired Ethernet - both interfaces get good addresses unplug cable, WiFi continues to work until shutdown. Next morning, repeat process. I've tried: turning WiFi off/on (there's a slider switch) disabling/re-enabling via Device Mangler uninstalling and reinstalling the driver for the 3945ABG... changing from Intel Pro/SET to Windows Wireless Zero Config (and back) restarting the router changing the static DHCP assignments at the router upgrading the router firmware, just on general principles The router/access point is pfSense 1.2.3RC1 (was 1.2.2); wireless card is Atheros-based. None of the 12 other users (5 with tablets) are having problems.

• How to build Visual Studio Setup projects (.vdproj) with TFS 2010 Build ?

  - by Vishal

  Out of the box, Team Foundation Server 2010 Build does not support building of setup projects (.vdproj). Although, you can modify DefaultTemplate.xaml or create your own in order to achieve this. I had to try bunch of different blog post's and finally got it working with a mixture of all those posts.   Since you don’t have to go through this pain again, I have uploaded the Template which you can use right away : https://skydrive.live.com/redir?resid=65B2671F6B93CDE9!310 Download and CheckIn this template into your source control. Modify your Build Definition to use this template. Unless you have CheckedIn the template, it wont show up in the template selection section in the process task of build definition. In your Visual Studio Solution Configuration Manager, make sure you specify to build the setup project also. You might get this warning in your build result: “The project file “*.vdproj” is not support by MSBuild and cannot be build. Hope it helps. Thanks, Vishal Mody Reference blog posts I had used: http://geekswithblogs.net/jakob/archive/2010/05/14/building-visual-studio-setup-projects-with-tfs-2010-team-build.aspx http://donovanbrown.com/post/I-need-to-build-a-project-that-is-not-supported-by-MSBuild.aspx http://lajak.wordpress.com/2011/02/19/build-biztalk-deployment-framework-projects-using-tfs2010/

• Showing content from pages at different URL's (masking), possibly with .htaccess

  - by zigojacko

  If I have URL's like:- domain.com/category/widgets/filter/blue domain.com/category/widgets/filter/red And it is pretty difficult to reconstruct them to something like:- domain.com/category/blue-widgets domain.com/category/red-widgets Is there any way at all that I can use URL rewrites or anything else with .htaccess or on the server to display the URL's as the domain.com/category/blue-widgets on the domain.com/category/widgets/filter/blue page? I've looked into masking URL's but got nowhere and this has been something bugging me for almost 6 months now. Is there any way to achieve what I want to do? FYI: This is a Magento website and the above process, I am wanting to implement for potentially hundreds of URL's. Edit To respond to @kkugelmann's answer:- I couldn't get your proposed RewriteRule to make a difference at all in the .htaccess file so I started testing a few things in this .htaccess tester:- The proposed RewriteRule didn't work in this tester:- However, the following did:- But adding any of these RewriteRule's into the website's .htaccess file did not rewrite the URL at all... Edit2 By the way, if I add [R=301,L] to the end of the URL rewrite rule, it does actually then rewrite the rule, but of course 301 redirects it as well which is unwanted behaviour. Edit3 I found another question with the same issue... And an accepted answer that solved the problem which seemed to be something to do with using mod_proxy and the [P] tag on the rule (if I try this, the page 404's).

• Get Started with JavaFX 2 and Scene Builder

  - by Janice J. Heiss

  Up on otn/java is a very useful article by Oracle Java/Middleware/Core Tech Engineer Mark Heckler, titled, “How to Get Started (FAST!) with JavaFX 2 and Scene Builder.”  Heckler, who has development experience in numerous environments, shows developers how to develop a JavaFX application using Scene Builder “in less time than it takes to drink a cup of coffee, while learning your way around in the process”. He begins with a warning and a reassurance: “JavaFX is a new paradigm and can seem a bit imposing when you first take a look at it. But remember, JavaFX is easy and fun. Let's give it a try.” Next, after showing readers how to download and install JDK/JavaFX and Scene Builder, he informs the reader that they will “create a simple JavaFX application, create and modify a window using Scene Builder, and successfully test it in under 15 minutes.” Then readers download some NetBeans files:“EasyJavaFX.java contains the main application class. We won't do anything with this class for our example, as its primary purpose in life is to load the window definition code contained in the FXML file and then show the main stage/scene. You'll keep the JavaFX terms straight with ease if you relate them to the theater: a platform holds a stage, which contains scenes. SampleController.java is our controller class that provides the ‘brains’ behind the graphical interface. If you open the SampleController, you'll see that it includes a property and a method tagged with @FXML. This tag enables the integration of the visual controls and elements you define using Scene Builder, which are stored in an FXML (FX Markup Language) file. Sample.fxml is the definition file for our sample window. You can right-click and Edit the filename in the tree to view the underlying FXML -- and you may need to do that if you change filenames or properties by hand - or you can double-click on it to open it (visually) in Scene Builder.” Then Scene Builder enters the picture and the task is soon done.

• How do you manage large web farms?

  - by Andrew Katz

  I have a quickly growing web farm running IIS 7 (30+ servers). All servers are identical copies of each other and all servers are physical. We update the software about once a month, and in the current process, we follow the following steps: Disable server from pool on F5 load balancer. Disable HTTP Keep-alives in IIS so connections drop quickly. Change default directory of website to new folder containing new binaries. Test server Enable HTTP Keep-alives. Enable server in F5 pool. Move to server 2 Microsoft used to have Application Center which was abandoned a while ago. They have made a second attempt with the Web Farm Framework, but this adds as much QA time testing the release package as it saves in the deployment. Has anyone seen a commercial off the shelf application that is tailored for managing and deploying to large web farms? Thanks!

• Should I start MCPD training now or wait for new exams?

  - by lunchmeat317

  i apologize if this question has been asked before, or if this is the wrong place to put it. I'm beginning my study track for the MCPD certification in Web Development. However, Microsoft plans to retire this certification on July 31st of 2013, along with two of the necessary tests to receive the certification. On MS's site, I can't find a newer certification path to take - I imagine that Microsoft will release new certification paths and new tests for their new software, but I don't know when that will happen. I don't really know anything about Microsoft's process, as this is the first Microsoft certification I'll be studying for. The bottom line is this - I don't want to lose six months waiting for a new test to appear that won't expire, but I don't want to rush to get a certification that will be invalid in six months (or have to reset any progress due to new study material). To those with experience in affairs like this - what is the best course to take, and can I maximize the time I have now (not wait for new testing material)? Is there any way to find material for the new tests that Microsoft will be rolling out? Thank you for your patience. If this is the wrong place to put this question, I would like to request that it be moved to the correct StackExchange site instead of being closed. Thanks for your help!

• Lubuntu Full Install on USB Drive with Full Disk Encryption and Grub2

  - by vivi

  I apologise for the wall of text, but I want you to scrutinize my thought-process to make sure there's no mistakes and no other way around it: I wish to have a full install of lubuntu with full disk encryption on one of my usb drives. The laptop I would be booting it from also has windows 7. I want to maintain that OS. From what I've read I must place grub2 on the usb drive so that: If I have the usb plugged in, the laptop would start lubuntu (having USB HD in the BIOS Boot options) If I don't have the usb plugged in, it would normally start windows 7. That's exactly what I want it to do. But: If I install from the normal .iso: Clicking "install lubuntu alongside them" would install it onto my normal HD. Clicking "Erase disk and install lunbuntu" would delete all the stuff I have in my HD and install lubuntu on it. Clicking "Something else" would allow me to choose to install lunbuntu and grub2 onto the usb drive, but would not provide it with encryption. So the normal .iso won't work for what I want. Then I found the alternate .iso and this tutorial: It allows me to install lubuntu with all the options I want and gives me the option to choose where to place the grub2! Hopefully there are no flaws in my train of thought. If there aren't, I have a few questions regarding that tutorial: The author says in his case choosing "Yes to install GRUB to your MBR" installed the grub to the usb drive's mbr. I can't have "in his case". I need to be sure that's what it will do, so that it doesn't mess up the windows boot loader. Choosing "no" would open this window and allow to choose where I want to install the grub. Unfortunately I don't understand which option I should type in the box to install it into the usb drive. Would removing my laptop's Hard Drive ensure that the grub is installed onto the usb drive if i picked first option, "yes"? I apologise once again for the wall of text and appreciate any help you guys can offer me.

• Does immutability entirely eliminate the need for locks in multi-processor programming?

  - by GlenPeterson

  Part 1 Clearly Immutability minimizes the need for locks in multi-processor programming, but does it eliminate that need, or are there instances where immutability alone is not enough? It seems to me that you can only defer processing and encapsulate state so long before most programs have to actually DO something. If a program performs actions on multiple processors, something needs to collect and aggregate the results. All this involves multi-process communication before, after, and possibly during some transformations. The start and end state of the machines are different. Can this always be done with no locks just by throwing out each object and creating a new one instead of changing the original (a crude view of immutability)? What cases still require locking? I'm interested in both the theoretical/academic answer and the practical/real-world answer. I know a lot of functional programmers like to talk about "no side effect" but in the "real world" everything has a side effect. Every processor click takes time and electricity and machine resources away from other processes. So I understand that there may be more than one perspective to answer this question from. If immutability is safe, given certain bounds or assumptions, I want to know what the borders of the "safety zone" are exactly. Some examples of possible boundaries: I/O Exceptions/errors Interfaces with programs written in other languages Interfaces with other machines (physical, virtual, or theoretical) Special thanks to @JimmaHoffa for his comment which started this question! Part 2 Multi-processor programming is often used as an optimization technique - to make some code run faster. When is it faster to use locks vs. immutable objects? Given the limits set out in Amdahl's Law, when can you achieve better over-all performance (with or without the garbage collector taken into account) with immutable objects vs. locking mutable ones? Summary I'm combining these two questions into one to try to get at where the bounding box is for Immutability as a solution to threading problems.

• What .NET objects should I use to create a cookie based session in MVC?

  - by makerofthings7

  I'm writing a custom password reset application that uses a validation technique that doesn't fit cleanly with ASP.NET Membership Provider's challenge questions. Namely I need to invoke a workflow and collect information from the end user (backup phone number, email address) after the user logs in using a custom form. The only way I know to create a cookie-based session (without too much "innovation" on my part) is to use WIF. What other standard objects can I use with ASP.NET MVC to create an authenticated session that works with non-windows user stores? Ideally I can store "role" or claim information in the session object such as "admin", "departmentXadmin", "normalUser", or "restrictedUser" The workflow would look like this: User logs in with username and password If the username and pw are correct a (stateless) cookie based session is created The user gets redirected to a HTML form that allows them to enter their backup phone number (for SMS dual factor), or validate it if already set. The user can then change their password using the form provided The "forgot password" would look like this User requests OTP code to be sent to the phone User logs in using username and OTP If the OTP is valid and not expired then create a cookie based session and redirect to a form that allows password reset Show password reset form, and process results.
