• What USB key would you recommend using for running a Windows 7 VM off of?

  - by Darryl Hein

  Because I can't find a good PHP editor for OSX, I develop in Windows with PhpEd. At the moment, my development time is split between a desktop and a laptop. To partially solve the problem of having 2 different environments, I have installed a virtual machine (through Virtual Box) and put the hard drive file on an external hard drive. At the moment, I've been connecting it through Firewire 800. I have 2 problems with this setup: (1) The hard drive is fairly large so to carry the laptop and hard drive I pretty much require a backpack. (2) The hard drive requires quite a bit of power and therefore reduces the battery life (by about 40%). My thought is to move the VM hard drive onto a USB key. I realize it will be slower, but as I'm just using it for PHP development, there isn't a lot of disk activity in the VM. The only really intense time is boot up, otherwise, it just about sits idle. Do anyone have any suggestions on a USB key to use for the VM? It would need to a minimum of 32GB.

• Windows desktop virutalization instead of replacing work stations

  - by Chris Marisic

  I'm head of the IT department at the small business I work for, however I am primarily a software architect and all of my system administration experience and knowledge is ancillary to software development. At some point this year or next we will be looking at upgrading our workstation environment to a uniform Windows 7 / Office 2010 environment as opposed to the hodge podge collection of various OEM licensed editions of software that are on each different machine. It occurred to me that it is probably possible to forgo upgrading each workstation and instead have it be a dumb terminal to access a virutalization server and have their entire virtual workstation hosted on the server. Now I know basically anything is possible but is this a feasible solution for a small business (25-50 work stations)? Assuming that this is feasible, what type of rough guidelines exist for calculating the required server resources needed for this. How exactly do solutions handle a user accessing their VM, do they log on normally to their physical workstation and then use remote desktop to access their VM, or is it usually done with a client piece of software to negotiate this? What types of software available for administering and monitoring these VM's, can this functionality be achieved out of box with Microsoft Server 2008? I'm mostly interested in these questions relating to Server 2008 with Hyper-V but fell free to offer insight with VMware's product line up, especially if there's any compelling reasons to choose them over Hyper-V in a Microsoft shop. Edit: Just to add some more information on implementation goals would be to upgrade our platform from a Win2k3 / XP environment to a full Windows 2008 / Win7 platform without having to perform any of that associated work with our each differently configured workstation. Also could anyone offer any realistic guidelines for how big of hardware is needed to support 25-50 workstations virtually? The majority the workstations do nothing except Office, Outlook and web. The only high demand workstations are the development workstations which would keep everything local.

• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• Parallels 6 - Is It Just Me or Does It Run Really Slowly?

  - by 5arx

  I've been running Parallels since version 2 with great success. I use it as my .Net development environment and over the last few years have converted so many others to the Parallels/Mac way of doing Windows/.Net development that I feel I should be getting perks/gifts and/or freebies from Parallels Corporation ;-) A month or so ago I upgraded to version 6 and ... immediately wished I hadn't. I'm currently running it on a laptop - a 2009 MacBook Pro (13"/2.53Ghz/4GB) while my MacPros at work and home are still running v5. I have seen nothing in v6 that makes me want to upgrade the install on those. The general problem is performance - upon starting or suspending a vm (always Windows 7 Ultimate), OS X slows down, quite often freezing for a minute or two at a time. The performance of the vms themselves are fine, but for me the point of this set-up is to be able to do web-browsing, email checking etc. on the OS X side of things while doing the stuff that can only be done on Windows (Visual Studio, SQL Server tools) on Windows. I have been using Parallels for a while so at least feel like I know what I'm doing so at the moment I am heading towards forming an opinion that its Parallels thats to blame. I've tweaked and tweaked all the vm configuration properties but to no avail. Support emails to the company have all received replies - there are no documented case of the issue you mention. Has anyone else seen this problem and if so, have you found a fix?

• pcfg_openfile: unable to check htaccess file, ensure it is readable

  - by rxt

  After moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however. The setup is a bit complex, as follows: I have Ubuntu 10.4 as development machine, trying to mimic the server as much as possible We use Eclipse + SVN and I create all projects in a local folder under my user account In /var/www-vhosts I create folders for each vhost, like this one: test.localhost test.local/index.php: includes the index file of the project test.local/.htaccess is a dynamic link to the htaccess file in a project subfolder I get the following error in the apache error log: [Thu Jul 08 15:55:56 2010] [crit] [client 127.0.0.1] (13)Permission denied: /var/www-vhosts/test.localhost/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable The problem seems to be the .htaccess file, or the link to it. When I empty the htaccess, nothing changes When I remove the link, the index-include produces some output (in the apache error log) When I remove the link and replace it with the actual file, I get another error: [Thu Jul 08 16:47:54 2010] [error] [client 127.0.0.1] Symbolic link not allowed or link target not accessible: /var/www-vhosts/test.localhost/test I'm lost here, don't know what to do next. Do you have any ideas what I can try? This setup has worked before, but I don't know what is different now.

• Are ZFS snapshots + S3 a viable backup system for several VMs and general fileserver storage?

  - by AllanA

  I've been tasked with setting up a backup system for my small office (around 12 people). Most of our production stuff is on the AWS cloud, so what I need to back up are some small office/development files (under 100G right now), plus our operational VMs and development, which round out to a bit under 1T. I just need something reliable, convenient, and straightforward. I'm comfortable with Linux, FreeBSD, and to some extent Solaris 10, so I'm leaning toward a full server rather than an appliance system ala Openfiler or FreeNAS. What I'm contemplating is a small fileserver for general storage and nightly backups of the virtual machines, followed up by an offsite backup to Amazon's S3 storage service. It'd be the usual incremental backups nightly and full backup weekly. My question is if using ZFS snapshots, both locally and dumped to S3 via 'zfs send [-i]', is a viable backup tool? Or should I stick to using Duplicity, or some other method entirely? ZFS snapshots on the internal fileserver/backup machine sound like a perfect way to provide quick and convenient data recovery, so I'm likely to go with that for local redundancy. (If you folks see scenarios where relying on ZFS snapshots would be worse than a more traditional archiving backup, feel free to convince me.) But are snapshots flexible enough to lean on for recovery from the loss of my backup server? Or am I better off with something more traditional? (feel free to recommend free or commercial backup solutions you favor.)

• Website hosted on my virtualbox web server not displaying images or applying css when viewed through phone

  - by WebweaverD

  I would really appreciate it if someone could help me. Please let me know if you need more info in the comments. My Set Up I have a windows 7 pc. On it I run a virtual box VM with a ubuntu 12 guest os and LAMP setup. I share files between the two machines using samba from linux to windows and using windows file sharing (Workgroup) the other way round. The vm is set up with a bridged network adapter and can happily serve web pages to my host machine. I use DHCP reservations on my home wireless router/modem to reserve an ip for the vm and give it a sitename.dev in my windows host file so I can access it at sitename.dev through the browser. The Problem So far so good but I have a dev project which needs a lot of mobile template development, now obviously I can use a browser plugin to simulate a mobile device but I would like to be able to see the real thing easily on my phone during development. So ideally I would like a similar setup on my iphone to my windows setup Now I'm not great on networking and dont have much experience with web server set up. So when I typed the ip of my virtual box into my iphone i wasnt expecting to see anything. I was pleasantly surprised when my site loaded up. The javascript even seems to be running but the images and css are not happening. My Question 1) What is happening here, is it something to do with the bridged set up on the vm network? 2)How do I make the sites load properly through my phone Notes I've also tried another phone. The same sites viewed on live servers work fine.

• Error at the end of APC install

  - by cinqoTimo

  I need to get APC running for a Drupal install of mine. I found a fairly concise guide at http://blog.4rev.net/2009-09/installing-apc-accelerator-into-php5-fedora-core-11/ for installing on FC11, only, I am using FC12. I figured I would give it a shot. I was able to run the following commands successfully - and yum installed fc12 versions of everything in the FC11 guide. yum install php-pear yum install php-devel httpd-devel yum groupinstall ‘Development Tools’ yum groupinstall ‘Development Libraries’ Then, I tried pecl install apc. Everything looked good until to got to the end, where it outputted the following error. /var/tmp/APC/php_apc.c: In function ‘zif_apc_compile_file’: /var/tmp/APC/php_apc.c:881: warning: unused variable ‘eg_class_table’ /var/tmp/APC/php_apc.c:881: warning: unused variable ‘eg_function_table’ /var/tmp/APC/php_apc.c: At top level: /var/tmp/APC/php_apc.c:959: error: duplicate ‘static’ make: *** [php_apc.lo] Error 1 ERROR: `make' failed Some people have had success with installing apc-beta, but that didn't work for me.. Any suggestions? Is there something I missed that is critical in the FC12 version?

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• SQL Server: Network pauses after installing cheap SATA card: Is there a solution?

  - by samsmith

  At the risk of being assigned to the "bad DBA" club... I did something desperate, and may have to undo it. Problem: After installing a low cost eSATA board, my SQL Server is intermittently unresponsive (seemingly when there is a lot of IO to the eSATA drive). Questions: 1) Is there a solution to the intermittent unresponsiveness that allows me to keep the eSATA in place? 2) Whether or not (1==true): What is a decent, low cost way to add 1-3 TB storage to SQL for non-critical SQL DBs? Detail: Our SAN is full, and expanding it is costly and will take a month. I have a pressing need to add 1-3 TB for some development DBs (e.g. not mission critical; data loss is OK). As a bandaid, I threw a $20 eSATA PCI board in the Dell 1950 server, and attached an external 2TB eSATA drive. This seemed to work fine, but I notice that our production SQL DBs, and even remote desktop, now experience network "pauses" that they never did before (with both SQL client apps and remote desktop throwing "networking problem" errors). This SQL Server has lots of memory, and runs an instance of SQL 2005 (where all line of business apps reside) and an instance SQL 2008 (for development db's). SQL Server RAM has been appropriately configured, and this setup has run great for years. The server is: Dell 1950 Win2003 x64 14GB RAM PERC controller, 2 mirrored hd's internal Dell SAN over gbit ethernet, dual homed 2 PCIx slots (1 used by NIC for SAN, 1 now in use for eSATA board) Thank you for suggestions!

• solution for an offline server

  - by dashmug

  I'm trying to setup a development server at work that will ideally be able to test drive a couple of projects in PHP, Rails, or Django (not always running at the same time). I develop the apps locally on a Mac and then I'll put the projects up on this server for testing with my actual users (non-techies) before deploying to a production server. My problem is that we have a very poor internet connection (almost negligible) at work and doing the usual apt-get/yum/ports (make, clean, install) processes for setting up servers always get their packages from online repositories somewhere. I know I could probably download the source and then compile them myself but that's going to be too much of a hassle for me. I'm thinking about two solutions: Plan A: Run a server VM on my Mac and then use this VM as the source repository for the offline server. I've read about Ubuntu's apt-proxy and it seems to be good enough though I haven't tried it yet. I'm not sure if this is possible but can I simply do apt-get install nginx --downloadonly so that the package and its dependencies will be downloaded into my VM and my server can use the VM as the source repo for apt-get? Plan B: Run a server VM on my Mac (which I can setup/update easily when I'm home) and then clone the VM to the offline development server. Maybe I should simply make the server a VM host so I can simply copy the VM over. I think this is okay for the first-time setup but subsequent updates will take too long (cloning the VM image). If I was working on Windows, I imagine it'd be easier because most services have an installer file that I can download and then run at the server. If you could suggest another way, it would be much appreciated. Update: From Michael Hampton's answer, I found a possible solution which is apt-cacher. I also found this page on Ubuntu's website. I wonder if there is a better tool than this one.

• IIS no longer saving session variables

  - by John

  I'm running IIS v7 on a Win7 development machine. I have PHP code that saves session variables and calls them back later. This has been working on this machine for some time. For some reason now, the session variables dissapear immediatly after saving. Code that used to work fine on http://localhost/, suddenly now does not. I have tested different browsers - the vars dissapear regardless of browser. I have tested identical code on different servers. The problem exists only on this development machine. I tried some code that saves a session var, then reads it back and displays it, then shows a link to click on to read it back and display again. What happens is the session var DOES get written and read back and displayed ok. But when you click the link to view it again, it's gone. I don't recall making any changes to IIS. But I did run several malware scanners and clean-up tools. Is anyone aware of any setting in IIS that disallows session vars? Any other throughts?

• Apache: Setting up local test server with subdomains

  - by RC

  Hi everyone, I have XAMPP running on my desktop machine, and I do all my work on it with no issue. http://localhost ---> points to public_html http://site1.localhost ---> points to site 1 http://site2.localhost ---> points to site 2 http://site3.localhost ---> points to site 3 Entering the above URLs in my web browser on the machine with Apache works great, and I can work on multiple sites within distinct subdomains. But what I want to do now is to transfer Apache and all the files to another Windows 7 machine within the LAN, but still be able to view the subdomains from my main development machine. With a vanilla XAMPP installation on the new hosting machine, entering the IP address of that machine (e.g. 192.168.1.10) into my development computer would send me to the main public_html folder. But how do I set up subdomains such that I can access it externally? For example, http://site1.devmachine Thanks for any help.

• Huh? JDK not found? (on Windows 7 64-bit)

  - by Android Eve

  I am setting up a development environment for the latest Android 2.3 on a fresh install of Windows 7 64-bit. I first installed the 64-bit JDK 6 (jdk-6u23-windows-x64.exe). Then, I installed 64-bit Eclipse Classic 3.6 (eclipse-SDK-3.6.1-win32-x86_64.zip). Then, I proceed to install the Android SDK Starter Package: installer_r08-windows.exe. But... upon start it says: "Java SE Development Kit (JDK) not found." Why? I just installed it. Is this a mismatch between 32-bit and 64-bit? How do I solve this? Update (1): I tried setting the %JAVA_HOME% environment variable, as well as setting the Installed JREs in Eclipse, as suggested below. None of these solved the problem. It appears that I am not the only experiencing the problem, as this thread suggests: http://stackoverflow.com/questions/1919340/android-sdk-setup-under-windows-7-pro-64-bit I wonder whether there is a 64-bit version of the Android SDK. Update (2): I used the zip version instead (android-sdk_r08-windows.zip), ran android.bat, updated all SDK packages, and installed the ADT plugin (8.0.1), not before having to check: 'Contact all update sites during install to find required software'. We'll see how this goes... Update (3): It worked! (going to accept @bubu's answer shortly) -- but why doesn't the emulator include the HelloAndroid app when I run it (Ctrl+F11) from Eclipse?

• What would prevent the same ActiveX control from downloading on one internal website but not another?

  - by ProfessionalAmateur

  We have two internal webservers for an application at my company, one is the development server and the other is production. This application server will deploy and install and ActiveX control to allow the use of specific functionality. The ActiveX control is the exact same on both servers. Last week suddenly when trying to install and run this ActiveX control from the development server stopped working. IE will still prompt the user to install it, but when select "Install this Add-on for all users on this computer", nothing happens. Another IE window pops open and immediately closes and that is it. It is almost as if a pop-up blocker is running (but it is not enabled). The kicker which has me completely stumped is that if we try the same thing on the Production server, everything works as we would expect. Items of interest: Both servers are in the 'Trusted Sites' No pop-up blocker in IE is activated ActiveX controls for Trusted and Intranet Sites are all enabled. Has anyone experienced something similar? I'm not a Windows administrator so please feel free to explain things as elementary as you see fit.

• My system is always disk-bound (the disk light is always on). Why is this?

  - by Scoobie

  I have been given a laptop by the good folks at my company on which to do my work (Java development). I usually use eclipse as my primary development platform. The laptop is a Dell D830 and runs Windows 7 - 32 bit. Although the processor supports a 64 bit instruction-set, licensing limits me to running the 32 bit OS. The HDD is a WD1600BEVT (Western Digital). I have noticed that my disk is always very slow. Windows start up is usually pretty quick, however as soon as I log on, my disk light stays on and usually, the laptop takes about 4 minutes (after logging in -- immediately upon getting the prompt to press Ctrl + Alt + Del to log in) before it's usable. Questions: Is this expected behavior? What can I do to examine the disk and determine the cause of the problem? What can I do to improve my disk's performance? Any optimizations you may be able to suggest? Other Questions: Some have suggested running Process Monitor (from sysinternals), but how would i get the log since start up? Instead of trying to fix this myself, should I simply push this onto the system administrator? Thanks all.

• Sourcecode for Paymentroll example in Robert C. Martin book

  - by bitbonk

  Throughout the book "Agile Principles, Patterns, and Practices in C#" by Robert C. Martin a small Paymentroll application is build. While most of the source code is printed in place, some classes are missing and some are incomplete. The book says on the firest page: The book includes many source code examples that are also available for download from the authors' Web site. Unfortunately this seems to be a lie. Unless either this is not the author's website (the book forgets to mention the authors website adress) or I am blind. Does anyone have the comlete source code for that book preferably in form of a Visual Studio project or knows where I can find it.

• ruby on rails named scope implementation

  - by Engwan

  From the book Agile Web Development With Rails class Order < ActiveRecord::Base named_scope :last_n_days, lambda { |days| {:conditions => ['updated < ?' , days] } } named_scope :checks, :conditions => {:pay_type => :check} end The statement orders = Orders.checks.last_n_days(7) will result to only one query to the database. How does rails implement this? I'm new to Ruby and I'm wondering if there's a special construct that allows this to happen. To be able to chain methods like that, the functions generated by named_scope must be returning themselves or an object than can be scoped further. But how does Ruby know that it is the last function call and that it should query the database now? I ask this because the statement above actually queries the database and not just returns an SQL statement that results from chaining.

• TFS and Project portal sync

  - by Tigran

  Just installed TFS 2008. Created a project with portal site. When I create a bug in TFS from Visual Studio I'd like to see that bug in the web portal. And the other way around. When I add a task in the web portal I'd like to see that in Visual Studio. It's as if the web portal is not connected to TFS. I'm using the MSF for Agile Software Development template. I just saw Team System Web Access. That's what I want in addition to the other pages Sharepoint portal provides. For example the Wiki page and calendar view. So one place to see all tasks lists and assign task and see other project related pages. Maybe be able to has the tasks due dates come up on the calendar. Many thanks

• implicit argument passing of super from method defined by define_method() is not supported. Specify

  - by jaycode

  Most of you should already know Pragmatic book's "Agile web dev with rails" (third edition). On page 537 - 541 it has "Custom Form Builders" code as follows: class TaggedBuilder < ActionView::Helpers::FormBuilder # <p> # <label for="product_description">Description</label><br/> # <%= form.text_area 'description' %> #</p> def self.create_tagged_field(method_name) define_method(method_name) do |label, *args| @template.content_tag("p" , @template.content_tag("label" , label.to_s.humanize, :for => "#{@object_name}_#{label}") + "<br/>" + super) end end field_helpers.each do |name| create_tagged_field(name) end end This code doesn't work with Ruby 1.9.1. It returns error as follows: implicit argument passing of super from method defined by define_method() is not supported. Specify all arguments explicitly. (ActionView::TemplateError) My question is: What should I change in the code to fix this? Thank you

• Whats the significance of named scope in rails?

  Before going for details. Question 1:-- Whats the meaning of scope here (ie named scope)? whats the benefits of using named scope? Now:- from agile development with rails book:-- class Order < ActiveRecord::Base named_scope :last_n_days, lambda { |days| {:conditions => ['updated < ?' , days] } } named_scope :checks, :conditions => {:pay_type => :check} end Such a named scope would make finding the last weeks worth of orders a snap. orders = Orders.last_n_days(7) Scopes can also be combined orders = Orders.checks.last_n_days(7) why we are using named_scope here. We can do the same using methods. Whats special thing we got using named_scope.

• What some good books on software testing/quality?

  - by mjh2007

  I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

• Getting started with modern software architecture and design using a book

  - by bitbonk

  I am a rather oldschool developer with some basic knowledge of software design principles and a good background on classic (gof) design patterns. While I continue my life as such I see lots of strange buzzwords emerge: Aspectoriented Design, Componentoriented Design, Domain Driven Design, Domain Specific Languages, Serviceoriented (SOA) Design, Test Driven Design, Extreme Programming, Agile Development, Continuous Integration, Dependency Injection, Software Factories ... Is there good book around that I can take with me on a roadtrip while it is taking me on a trip through all (most) of the above, delivering an 10,000 foot view on modern software archiceture and desing principles and approaches.
