• Altering the Windows 7 grouping thumbnail preview

  - by russ

  I like the windows 7 grouping behaviour for multiple similar windows, except when I have multiple Explorer windows open. In this case, showing thumbnails of each open explorer window is next to useless, and I would like to know how to either: Disable thumbnail display completely (but preserve the grouping behaviour) Disable thumbnail display for a subset of programs (all explorer.exe instances) Change the number of similar programs that are open before the grouping behaviour falls back on a more sensible text preview when hovering over the taskbar icon (currently 14 or over) I don't particularly want to disable any other features of windows to get this behaviour, so disabling the theme compleletely isn't what I want to do. I definitely want to keep the grouping behaviour. Its just those thumbnail previews I would like to alter. Here are some screen shots of what I don't want, and what I do want: http://dl.dropbox.com/u/13184372/StackOverflow/BadGrouping.png http://dl.dropbox.com/u/13184372/StackOverflow/GoodGrouping.png

• Dynamic authentication realms in Apache

  - by Cogsy

  I have a front end server acting as a gateway proxy for many (a dynamic 'many') building monitors with embedded webservers. They are accessed with a URL like: http://www.example.com/monitor1/ http://www.example.com/monitor2/ ... I'm trying to restrict access to these monitors to only the users that own them. So what I need is a way of specifying rights to users or groups for specific directories. The standard auth mechanisms I see in Apache won't work because I need to specify every location. I'd prefer some dynamic map or script. Any suggestions?

• Best CMS for review-type sites

  - by Pru

  Is there an ideal CMS for making a review site? By review site, I mean like a restaurant review site where you have each entry belonging to different major categories like Cuisine and City. Then users can browse and filter by each or by combination (Chinese Food in Los Angeles, with suggestions of other Chinese restaurants in LA, etc). Furthermore, I'd want it to support other fields like price, parking, kid-friendliness, etc. And to have users be able to filter by those criteria. I've been told that with a combination of custom taxonomies, plug-ins and many clever little queries, that Wordpress 3.x can handle this. But I'm having a heck of a time with it getting into the nitty gritty, and that's where I find the community support is lacking. The sort of stuff you'd think would work in WP, like making one parent category for Cuisine and one for City, don't really work once you get further in and start trying to pull it all together. Then you find these blog posts where people say, "This example shows that one could create a huge movie review site using custom taxonomies..." but when you go and try it you hit all sorts of challenges and oddities that point a big long finger at Wordpress being in fact a blogging platform. The best I came up with was one category for the cuisine and one tag for the city, then I created a couple of custom tag-like taxonomies for the other features. It's quite a mess to try to figure out how to assemble all of that into a natural, intuitive site. I expect a few versions down the road WP will be able to do these sorts of sites out of the box. So I thought I'd take a step back before I run back into the Wordpress fray and find out if maybe there is another platform better suited to this sort of relational content site. Directory scripts in some ways offer many of the features I'm looking for, but I need something more flexible and, hopefully, interactive (comments, reviews). I'm especially looking for feedback from people who've crafted sites like this. Thanks!

• Introducing RedPatch

  - by timhill

  The Ksplice team is happy to announce the public availability of one of our git repositories, RedPatch. RedPatch contains the source for all of the changes Red Hat makes to their kernel, one commit per fix and we've published it on oss.oracle.com/git. With RedPatch, you can access the broken-out patches using git, browse them online via gitweb, and freely redistribute the source under the terms of the GPL. This is the same policy we provide for Oracle Linux and the Unbreakable Enterprise Kernel (UEK). Users can freely access the source, view the commit logs and easily identify the changes that are relevant to their environments. To understand why we've created this project we'll need a little history. In early 2011, Red Hat changed how they released their kernel source, going from a tarball that had individual patch files to shipping the kernel source as one giant tarball with a single patch for all Red Hat-introduced changes. For most people who work in the kernel this is merely an inconvenience; driver developers and other out-of-kernel module developers can see the end result to make sure their module still performs as expected. For Ksplice, we build individual updates for each change and rely on source patches that are broken-out, not a giant tarball. Otherwise, we wouldn’t be able to take the right patches to create individual updates for each fix, and to skip over the noise — like a change that speeds up bootup — which is unnecessary for an already-running system. We’ve been taking the monolithic Red Hat patch tarball and breaking it into smaller commits internally ever since they introduced this change. At Oracle, we feel everyone in the Linux community can benefit from the work we already do to get our jobs done, so now we’re sharing these broken-out patches publicly. In addition to RedPatch, the complete source code for Oracle Linux and the Oracle Unbreakable Enterprise Kernel (UEK) is available from both ULN and our public yum server, including all security errata. Check out RedPatch and subscribe to [email protected] for discussion about the project. Also, drop us a line and let us know how you're using RedPatch!

• Windows 7: How to stop/start service from commandline (like services.msc does it)?

  - by john

  I have developed a program in Java that uses on a local SQL Server instance to store its data. On some installations the SQL Server instance is not running sometimes. Users can fix this problem by manually starting the SQL Server instance (via services.msc). I am thinking about automating this task: the software would check if the database server is reachable, if not try to (re)start it. The problem is that on the same user account the Services can be stopped /started via services.msc (without any UAC prompt), but not via (non-elevated) command line. The operating system seems to treat services.msc differently: c:\>sc start mssql$db1 [SC] StartService: OpenService FEHLER 5: Zugriff verweigert (Access denied) c:\>net start mssql$db1 Systemfehler 5 aufgetreten. Zugriff verweigert (Access denied) So the question is: how can I stop/start the service from a java-program/command line without having my users to use services.msc (preferrably via on-board-tools)

• What TLDs should I use for my NS records for redundancy? (DNSSEC support required)

  - by makerofthings7

  Question As a general practice, is it a good idea to use multiple TLDs for the name servers? How should I choose between which TLD would be a good candidate for being the root server for my NS name? More Info I am switching over 800 DNS zones to an outsourced DNS provider. I originally planned on setting the zone names to nsX.company.com, but think it would be best to have multiple TLDs such as .net , .org and .info Since I plan on supporting DNSSec at company.com I think all the 1st tier Name servers must support it as well. Part of the inspiration for this question came from our provider UltraDNS. In their configuration screen for our domains, they actively verify and alert us if our name servers aren't exactly: pdns1.ultradns.net pdns2.ultradns.net pdns3.ultradns.org pdns4.ultradns.org pdns5.ultradna.info pdns6.ultradns.co.uk

• Automatic switching between monitor configurations

  - by Michael Aquilina

  I have a laptop and an external monitor and i was wondering if there was a simple approach to switching between multiple monitor configurations based on the detected available displays. For example: When i am at home and i plug in my external monitor i would like this to automatically become enabled and the laptop screen to become disabled. As soon as i pull out the display cable for the external monitor, i would like the laptop screen to automatically become enabled. I was expecting this to just "work" just like it does in windows - but it seems to be much harder than that. I am aware of the xrandr command to turn displays on and off but i cannot seem to find a way to get this to work the way i describe above. I had also found this post about switching between multiple monitor configurations and the results seem a bit inconclusive. However i was hoping that with xrandr there would be a simpler solution. For me, the fact that when i pull out my external monitor the screen just goes black and i get an error message is a big issue holding me back from making the complete switch to linux as i move around alot as a student. My OS of choice is currently Kubuntu 12.04 but i am willing to change to something else if it provides a better way of setting up the described setup.

• Mysql Encryption and Key managment

  - by microchasm

  I am developing a local intranet system in PHP/MySQL to manage our client data. It seems that the best practice would be to encrypt the sensitive data on the MYSQL server as it is being entered. I am not clear, though, on what would be the best way to do this while still having the data readily accessible. It seems like a tough question to answer: where is the key(s) stored? How to best protect the key? If the key is stored on each users' machine, how to protect it if the machine is exploited? If the key is exploited, how to change the key? If the key is to be stored in the db, how to protect it there? How would users access it? If anyone could point me in the right direction, or give some tips I'd be very grateful. Thanks.

• Graphing per-user CPU usage on a Linux machine

  - by mart1n

  I want to graph (graphical output would be great, i.e. a .png file) the following situation: I have users A, B, and C. I limit their resources so that when all users run a CPU intensive task at the same time, those processes will use 25%, 25%, and 50% of CPU. I know I can get the real-time stats using top but have no idea what to do with them. I've searched through the huge top man page but haven't found much on the subject of outputting data that can be graphed. Ideally, the graph would show a span of maybe 30 seconds. Any ideas how to achieve this?

• cookie not being sent when requesting JS

  - by Mala

  I host a webservice, and provide my members with a Javascript bookmarklet, which loads a JS sript from my server. However, clients must be logged in, in order to receive the JS script. This works for almost everybody. However, some users on setups (i.e. browser/OS) that are known to work for other people have the following problem: when they request the script via the javascript bookmarklet from my server, their cookie from my server does not get included with the request, and as such they are always "not authenticated". I'm making the request in the following way: var myScript = eltCreate('script'); myScript.setAttribute('src','http://myserver.com/script'); document.body.appendChild(myScript); In a fit of confused desperation, I changed the script page to simply output "My cookie has [x] elements" where [x] is count($_COOKIE). If this extremely small subset of users requests the script via the normal method, the message reads "My cookie has 0 elements". When they access the URL directly in their browser, the message reads "My cookie has 7 elements". What on earth could be going on?!

• Group Policy for Setting Passwords: Server 2003 Domain

  - by user1236435

  In my 2003 domain, I am being requested to set a password policy to require passwords to expire every 4 months, and also require users to change their password on their next login, due to a security issue. In my domain, my OU's are setup by location, then drilled down to city, then the users and computers are in separate sub-domains. My question is, how do I set this up for my domain? Will I need to set the policy up for loop back? Can I configure this for just a specific OU? Any suggestions on how to move forward? Any advise is much appreciated, and thanks in advance!

• Need to include Calendar and Email in own CRM system. Whose?

  - by PurplePilot

  I am writing a web based application that needs to have some elements of CRM in it but I cannot use an of-the-shelf CRM to do what I want. (Honestly we have been through it all and it will not work). Now while Tasks, Calls, Meetings and Notes are straightforward the idea of reinventing Mail and Calendars seems a waste of time and effort and also unproductive as most users already have their own and it simply adds to the complexity of my application and hacks users off. My thoughts are going around using Outlook and or GMail/iCal and or Mac Mail/iCal and or Thunderbird and importing the relevant data or if possible integrating it into the application. Any thoughts? Anyone got any experience of this can point me in a few directions. N.B. Not looking for an answer as too complex just some pointers and thoughts. Thanks. p.s. We did look at Sugar CRM as the basis for our project and it is useful to get best practice from but as I say it was not useable due to how we are structuring our software, not Sugar's fault.

• Programmatic, script-based, or command line method to change starting program for user on Windows Server 2000/2003?

  - by Joe Majsterski

  I have written an app that we want to distribute to a large number of customers to be used as the shell program when they log onto their server with a particular admin account. I have figured out how to change the starting program by going to Administrative Tools->Computer Management->System Tools->Local Users and Groups->Users, selecting the properties for the user, going to the Environment tab, and changing the program file name under "Starting program" to my new app. But is there a way I could do this with some code that could be sent out and run on all these servers?

• Disable address bar in Internet Explorer 9

  - by token

  I'm trying to disable the address bar in IE9. I've done a significant amount of searching on this and just can't seem to find a way to make it happen. A lot of web resources discuss how to do it in IE8, but not IE9. The reason you might ask? I have an application being hosted in a remote desktop farm that links to web pages outside of the application into Internet Explorer. I need to ensure users are limited to just going to the pages the program pushes them to. I realize I could use a proxy server to limit where they can go, but I'm trying to find a really simple way to just disable the address bar instead. I can't use Kiosk mode because it puts the browser into full screen mode. This won't work for my situation as I need to give users what appears to be a regular browsing experience without an address bar.

• pscp: how to copy a file from a windows machine to a non-home location on another windows machine?

  - by help

  I want to copy a file from C:\temp on MachineA to C:\final on MachineB. I tried to use the following command, but it gave me an error (permission denied): C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:C:\final\test.txt C:\temp\test.txt It turned out I can only access C:\users\direcpc in my source computer. So if I put the file in C:\users\direcpc\text.txt, then it would work: C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:/test.txt C:\temp\test.txt But I want to access any location on my source computer instead of just my user home directory, is there a way to do this?

• Which programming language should I choose I want to build this website ...? [closed]

  - by Goma

  Assuming that I will start with just phot sharing website. Every user can add comments to any photo. After that the site will contain news (general news), the admin can add any news and the moderators as well while the users can also add comments on this news. The website will aslo provide photos uploader, so every user will have up to 20 MB ti upload any photos they want. Other users can see these photos or can not depending on the option that the main user chose(if he wants to publish his photos or not). The site should have a small type of forum which provide the ability for admin to ad categories and for user to add topics and replies for each topic in these categoris. These are the things that I can think of now, but the website will add other features as well and services later on. Can you tell me now which programming language can help me to do all that? I need a programming language that provdies the follwing: 1- speed load for pages of the site. 2- easy to add more functions quickly and easy to edit code for any reason. 3- Secure 4- fast in displaying infromation from database.

• Oracle Virtual Desktop Infrastructure

  - by Fat Bloke

  A lot of the recent blog entries here have been about Oracle VM VirtualBox, possibly the coolest personal desktop virtualization product known to man. Deploying VirtualBox on your PC or Mac lets you run many virtual desktops at the same time to one user, you. But did you know that VirtualBox can also power an Enterprise-scale virtual desktop deployment too, delivering many desktops to many users?  As part of another Oracle product, Oracle Virtual Desktop Infrastructure (VDI), VirtualBox can run your Windows, Linux or Solaris desktops on servers located in the datacenter. Oracle VDI orchestrates the whole deal by looking after : creating or cloning the virtual desktops from a master template; managing the lifecycle of the desktops (create, start, suspend, resume, stop, delete); assigning which users get which desktops;  delivering easy and fast access to these virtual desktops from almost any device, such as existing PCs or Macs, iPads, or specially designed Sun Ray client devices too; load balancing and session management of all of this.  Architecturally the solution looks something like this: This is an increasingly hot area of the IT landscape, so the Fat Bloke has decided to create a new blog category (VDI) and dedicate a few blog entries to look into this in a bit more detail over the next few weeks. Watch this space... - FB

• How do I know if 'hg clone' is doing the work remotely?

  - by jjfine

  I've got a very simple windows install of Mercurial on my machine. The 'central' repository is located at //mymachine/hg-repos/central. I want remote (VPN) users to be able to create clones of this repository in the hg-repos directory because it gets daily backups. I have given these users full control of the hg-repos directory. My question is this: If I'm on a remote machine, and I run the command: hg clone //mymachine/hg-repos/central //mymachine/hg-repos/central-copy ...is the remote machine doing most of the work? I don't want the client to have to download all of the central repository and then upload it all back because people are going to be using this from across the country. But I suspect this is what's happening here since it works so easily.

• How do I start a cloud9 service

  - by Lord Loh.

  Cloud9 is a free IDE available from https://github.com/ajaxorg/cloud9/ under GPLv3. I would like to use this to set up a service like https://c9.io/. The Cloud9 documentations do not mention anything about it. The Cloud9 documentation assume a sing user on localhost or bind to another address without one hard set username and hard set password. How do I run cloud9 IDE on my computer allowing multiple users? Are there any documentations? This is the closest to what I found - https://github.com/avgp/cloud9hub (for multiple workspaces)

• Server 2003 Filter mobile devices via MAC

  At one of my client's sites I need to keep my users unauthorized devices off the wireless. They all know the SSID and Password because many of them have laptops that need the wireless. I'm running out of IP address's and we have sent out numerous emails asking them to stay off, but like most users they ignore IT's email. I'm currently running Server 2003 as the GC/DC (but have 2008 servers in place) and 2 Netgear WNAP320. I've seen several posts similar to what I'm looking for but they seem to deal with Linux. My question is how do I go about doing this without migrating (scheduled for the end of the year) to a new server and is it possible to do this within Server 2003? Thanks msindle

• Automated VLAN creation with residential Wireless devices

  - by Zephyr Pellerin

  We've got a few WRT devices from Linksys here, and the issue has arisen to deploy them in a relatively small environment, However, in the interest of manageability we'd like to be able to automatically VLAN (ideally NOT subnet) every user from one another. It seems obvious to me that the default firmware isn't capable of this - can OpenWRT/Tomato/DD-WRT support any sort of functionality such that new users are automatically VLANed or otherwise logically separated from other users? It seems like there's an easy IPtables or PF solution here, but I've been wrong before. (If that seemed a little ambiguous, heres an example) User 1 sends DHCP request to server, new VLAN (We'll call VLAN 1) is created, user is placed in that VLAN. Then, user 2 sends a DHCP request and is placed in VLAN 2 etc. etc.

• Need some critique on .NET/WCF SOA architecture plan

  - by user998101

  I am working on a refactoring of some services and would appreciate some critique on my general approach. I am working with three back-end data systems and need to expose an authenticated front-end API over http binding, JSON, and REST for internal apps as well as 3rd party integration. I've got a rough idea below that's a hybrid of what I have and where I intend to wind up. I intend to build guidance extensions to support this architecture so that devs can build this out quickly. Here's the current idea for our structure: Front-end WCF routing service (spread across multiple IIS servers via hardware load balancer) Load balancing of services behind routing is handled within routing service, probably round-robin One of the services will be a token Multiple bindings per-service exposed to address JSON, REST, and whatever else comes up later All in/out is handled via POCO DTOs Use unity to scan for what services are available and expose them The front-end services behind the routing service do nothing more than expose the API and do conversion of DTO<-Entity Unity inject service implementation to allow mocking automapper for DTO/Entity conversion Invoke WF services where response required immediately Queue to ESB for async WF -- ESB will invoke WF later Business logic WF layer Expose same api as front-end services Implement business logic Wrap transaction context where needed Call out to composite/atomic services Composite/Atomic Services Exposed as WCF One service per back-end system Standard atomic CRUD operations plus composite operations Supports transaction context The questions I have are: Are the separation of concerns outlined above beneficial? Current thought is each layer below is its own project, except the backend stuff, where each system gets one project. The project has a servicehost and all the services are under a services folder. Interfaces live in a separate project at each layer. DTO and Entities are in two separate projects under a shared folder. I am currently planning to build dedicated services for shared functionality such as logging and overload things like tracelistener to call those services. Is this a valid approach? Any other suggestions/comments?
