• shrink ext4 partition

  - by user276851

  My question is similar to Move ext4 partition, but the challenge I couldn't figure out is how to shrink a partition from the start. So suppose originally the partition (with raid) is like this. (************** /dev/md127 ***************) After resizing, I want to achieve like this. (*** unallocated ***)(**** /dev/md127 ****) Note, I cannot use gparted, and parted does not support ext4. The commands I have tried so far, % resize2fs -p /dev/md127 1676G # <== This is good. % lvreduce -L 1676G /dev/md127 Path required for Logical Volume "md127" Please provide a volume group name Run `lvreduce --help' for more information. Failed here, I guess it may be because the underlying partition is primary and the lvreduce only works on logical? Anyway, no idea. Then after that, I am thinking to create another partition right after this one, copy the data to that partition, and remove this one, like. 1. (************** /dev/md127 ***************) 2. (**** /dev/md127 ****)(*** new partition **) 3. (*** unallocated ****)(**** /dev/md127 ****) Thanks for the help.

• Informing GUI objects about screen size - Designing

  - by Mosquito

  I have a problem with designing classes for my game which I create. In my app, there is: class CGame which contains all the information about game itself, e.g. screen width, screen height, etc. In the main() function I create a pointer to CGame instance. class CGUIObject which includes fields specifying it's position and draw() method, which should know how to draw an object according to screen size. class CGUIManager which is a singleton and it includes a list of CGUIObject's. For each object in a list it just calls draw() method. For clarity's sake, I'll put some simple code: class CGame { int screenWidth; int screenHeight; }; class CGUIObject { CPoint position; void draw(); // this one needs to know what is a screen's width and height }; class CGUIManager // it's a singleton { vector<CGUIObject*> guiObjects; void drawObjects(); }; And the main.cpp: CGame* g; int main() { g = new CGame(); while(1) { CGUIManager::Instance().drawObjects(); } return 0; } Now the problem is, that each CGUIObject needs to know the screen size which is held by CGame, but I find it very dumb to include pointer to CGame instance in every object. Could anyone, please, tell me what would be the best approach to achieve this?

• Inventory Consignment Flow

  - by ipohfly

  Not sure whether this is the right place to ask this question, but here goes.. Currently I have requirement to add support for consignment transaction in our inventory module. I have a very limited understanding of what consignment means in inventory, i.e. Customer get stocks/products from Seller without actually buying them, the product just resides in the Customer's inventory and it's still owned by the Seller. Only when the Customer actually buy the stocks then only will the ownership of the stock is transferred. The issue is i can't imagine how the data will be presented to both the Customer and the Seller. What i know is that i would need to deduct the stock from the Seller's inventory when the Customer raise a request to get the stock through consignment, but what about the 'ownership' of the stocks/products? Does that mean i would need to create another column in my table to state that for each inventory it is owned by who? Anywhere i can get information on how i should work out an inventory module like this? Thanks.

• How is it possible for SSD's drives to have such a good latency?

  - by tigrou

  First time i read some information about SSD's, i was surprised to learn they internally use NAND flash chips. This kind of memory is generally slow (low bandwidth) and have high latency while SSD's are just the opposite. But here is how it works : SSD drives increase their bandwidth by using several NAND flash chips in parallel. In other words, they do some data striping (aka RAID0) across several chips (done by the controller). What i don't understand is how SSD's drives have such a low latency, whereas they are using NAND chips? (or at least lot better than what a typical single NAND chip would do) EDIT: I think under-estimate NAND chip capabilities. USB drives, while powered by NAND's are mostly limited by USB protocol (which have a pretty high latency) and the USB controller. That explain their poor performance in some cases.

• How to reduce 3rd party repository priority in apt

  - by carlosz

  I'm using Debian Testing together with the Deb Multimedia (previously Debian Multimedia) repository for testing. I want to reduce the priority of the deb-multimedia packages so it only installs certain packages. I've tried with: Package: * Pin: release o="Unofficial Multimedia Packages" Pin-Priority: 10 and Package: * Pin: origin "mirror.home-dn.net" Pin-Priority: 10 But neither works, the packages still have the default priority (500). The Release file from the repository looks like this: Archive: testing Version: None Component: main Origin: Unofficial Multimedia Packages Label: Unofficial Multimedia Packages Architecture: amd64 What am I doing wrong? Edit: It worked when I used the Version information instead: Package: * Pin: release v=None Pin-Priority: 10 But I still don't know the reason the other filters didn't work.

• Server Running but unable to log in to it

  - by Funky Si

  I have a Windows Server 2003 server that is running sql server. Users can access the databases running on it fine, but I am unable to log on to it by remote desktop or directly at the machine. I am able to view the event logs remotely and I can't see anything that shouts out as being a problem. What options can people think of for regaining access to this server or finding out more information about the problem? I am able to reinstall the operating system but would like to leave that as a last resort.

• Hyper V cluster - one VM won't migrate

  - by Chris W

  We have a Failover Cluster built up on 6 blades, each running Hyper V. Each box is running Server 2008 R2. We've got a number of VMs running that all have the same basic config: VHD stored on a cluster shared volume. 2 virtual NICs (1 for LAN connection and 1 for SAN connection). All of our VMs will happily migrate between any other blade apart from one single VM which is running fine on it's current blade but will not migrate to any other location. What could be the cause of it or where should I look to get a detailed error message as I can't seem to find much information logged in any of the logs. Edit: I know the usual culprit is mis-matching resource names. We've already been there with the NICs named differently on some of the blades. As far as we can tell now everything looks to be identical on each bit of metal.

• I'm trying to set up a LAMP server so it's totally anonymous, any suggestions?

  - by flexterra

  I'm going to set up a web service which will use the LAMP stack. One of the most important features of the site is that it should be anonymous. We thought that a cool thing will be if the server didn't made any logs that could potentially identify a user. I'm working on a web app for a news organization. They want a site to allow people to sumbit news leads and tips (text / files) to journalists. We think if we can provide good anonymity people will be more inclined to provide information. We will also teach how to use stuff like TOR as an extra precaution for whistleblowers Is this even possible? Any suggestions of obscure things we should look into?

• CMS and Databases vs. DIY

  - by hozza

  I have been programming for many years now, primarily in PHP and the like and would consider myself an intermediate programmer. Some of my online projects have now gone global and very widely used, i am now in deep thought about scalability etc. All of my systems so far are written in PHP, no known database structure such as MySQL etc. Instead our databases use an 'operating system style' method of storing information, files and folders if you will. We also do not use any outside/third-party software or CMS, so far this has work out extremely well. Most people, when they hear about the way we do things, criticize and say that is an idiotic idea but normally after seeing our systems in more dept are converted to our way of doing things. Is it really that bad to not use a standard databasing systems and only using the one (slightly heavier than others) language of PHP? How well on the face of it will this kind of setup scale? N.B. Our systems include things such as account and user management, documentation development and task/project managing.

• Cannot access an application folder in Program files

  - by GiddyUpHorsey

  I recently installed Windows 7 Professional 64bit on a new machine. I installed an application using a ClickOnce installer. The application runs fine, but I cannot access the application folder it created in c:\Program files (x86). It bombs with access denied. I try to view the properties on the folder and it takes about 1 minute to display (other folders take 1 second). It says I cannot view any information because I'm not the owner. It doesn't say who the current owner is (instead - Unable to display current owner.) but says I can take ownership. When I try it fails again with Access Denied, even though I have administrative permissions. Why can't I access this folder nor take ownership?

• Single CAS web application in a cluster

  - by Dolf Dijkstra

  Recently a customer wanted to set up a cluster of CAS nodes to be used together with WebCenter Sites. In the process of setting this up they realized that they needed to create a web application per managed server. They did not want to have this management burden but would like to have one web application deployed to multiple nodes. The reason that there is a need for a unique application per node is that the web-application contains information that needs to be unique per node, the postfix for the ticket id.  My customer would like to externalize the node specific configuration to either a specific classpath per managed server or to system properties set at startup.It turns out that the postfix for ticket ids is managed through a property host.name and that this property can be externalized.The host.name property is used in: /webapps/cas/WEB-INF/spring-configuration/uniqueIdGenerators.xmlIt is set in /webapps/cas/WEB-INF/spring-configuration/propertyFileConfigurer.xmlin a PropertyPlaceholderConfigurer.The documentation for PropertyPlaceholderConfigurer:http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.htmlThis indicates that the properties defined through the PropertyPlaceHolderConfigurer can be externalized.To enable this externalization you would need to change host.properties so it is generic for all the managed servers and thus can be reused for all the managed servers: host.name=${cluster.node.id}Next step is to change the startup scripts for the managed servers and add a system property for -Dcluster.node.id=<something unique and stable>.Viola, the postfix is externalized and the web application can be shared amongst the cluster nodes.

• How to enable the flash player plugin in IE8?

  - by Nik Reiman

  I updated to IE8 the other day on my Vista laptop, mostly because Windows Update kept bugging me about it. As a Chrome user, I don't really care so much about IE8, but I do have to use it occaisionally to test website compatibility. At any rate, flash seems to be completely deactivated, and I don't see a place to re-enable it anywhere in the preferences. I've done a bit of googling on the issue, but only found information about how to disable flash, not how to actually enable it. I have the flash 10 debug player installed, and it works fine with Chrome and Firefox. What could be the matter?

• Take a snapshot with JavaFX!

  - by user12610255

  JavaFX 2.2 has a "snapshot" feature that enables you to take a picture of any node or scene. Take a look at the API Documentation and you will find new snapshot methods in the javafx.scene.Scene class. The most basic version has the following signature: public WritableImage snapshot(WritableImage image) The WritableImage class (also introduced in JavaFX 2.2) lives in the javafx.scene.image package, and represents a custom graphical image that is constructed from pixels supplied by the application. In fact, there are 5 new classes in javafx.scene.image: PixelFormat: Defines the layout of data for a pixel of a given format. WritablePixelFormat: Represents a pixel format that can store full colors and so can be used as a destination format to write pixel data from an arbitrary image. PixelReader: Defines methods for retrieving the pixel data from an Image or other surface containing pixels. PixelWriter: Defines methods for writing the pixel data of a WritableImage or other surface containing writable pixels. WritableImage: Represents a custom graphical image that is constructed from pixels supplied by the application, and possibly from PixelReader objects from any number of sources, including images read from a file or URL. The API documentation contains lots of information, so go investigate and have fun with these useful new classes! -- Scott Hommel

• What is an Acer Converter Port?

  - by ShadowHero

  What is this port "Acer Converter Port"? Very little information can be found on the internet. It's basically the same as miniDP? Can I connect a monitor like Dell U2713H on this one? EDIT From this page: http://acer.custhelp.com/app/answers/detail/a_id/30837/~/frequently-asked-questions-on-the-aspire-r7-series 9. Can I connect a DisplayPort monitor to the Acer Converter Port? The Acer Converter Port uses the same physical port as a Mini DisplayPort, but is designed to connect to an Acer proprietary cable. If you connect a DisplayPort monitor, Acer cannot guarantee the functionality of the monitor. No damage should occur to either monitor or notebook by connecting a Mini DisplayPort cable. So, the question is, can someone confirm this will work for sure?

• Windows Server 2003 stops sharing a folder when the server reboots [closed]

  - by evolvd

  I have a file server that will stop sharing a particular folder once the server is rebooted. This problem happened after the server went through a p2v migration. There are no events that seem to correlate to this issue. I was reading http://support.microsoft.com/default.aspx/kb/870964 but I don't think this applies and there are other shares on the same drive that are still there after a reboot. To be clear about the issue; When the server reboots share x is no longer shared any more but share y and z are still there. This has nothing to do with users not being able to see the share. On the server its self the folder that was shared is no longer shared. I wish I had more information to post but after hours on this issue I can't find a way to move forward.

• Intermittent HTTP 401 errors

  - by forthrin

  I am using an Intranet solution which requires basic HTTP login. However, there is an intermittent error which requires me to log in again, and then the server says "Forbidden" whether I give the correct login information or not. To add insult to injury, Safari (and Chrome) seems to show the login dialog for every included resource in the HTML, and it's impossible to cancel this modal dialog sequence, so the whole browser is blocked until I've pressed Esc some 30 odd times. After an hour, I may gain access again, without having really done anything. My questions: What could cause temporal 401 errors? Why do the browsers show the login dialog 30 times per page load (assumedly for every included resource in the HTML from the same domain)?

• When RDP as a Domain User, Smart Card Requested

  - by Paul

  My W8 machine is connected to domain zen. If I rdp to the W8 machine, I can log in as a local user without problems. If I try to log in as a domain user, I am prompted for a smart card instead of a password. Any ideas why? Note that Interactive login: require smart card is disabled in group policy: And here is the output from rsop.msc: Some additional information on this one. If my connecting machine is on the same domain/network as the W8 machine, then I am prompted for a password as usual. If the machine is remote, on a different domain, then I am prompted for a smart card. In addition, the machine I am connecting from that gets the smartcard prompt is an XP box. I haven't isolated exactly which of these factors triggers the different response.

• A tip: Updating Data in SharePoint 2010 using REST API

  - by Sahil Malik

  SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

• Creating deterministic key pairs in javascript for use in encrypting/decrypting/signing messages

  - by SlickTheNick

  So I have been searching everywhere and havn't been able to find anything with the sufficient information I need.. so Im a bit stumped on this one at the moment What I am trying to do is create a public/private key pair (like PGP) upon a users account creation, based on their passphrase and a random seed. The public key would be saved on the server, and ideally the private key would never be seen by the server whatsoever. The user could then sign in, and send a message to another user. Before the message is sent, the senders key pair would be re-generated on the fly based on their credentials (and maybe a password prompt) and used to encrypt the message. The receiver would then use their own re-generated private key to decrypt said message. The server itself should never see any plaintext passwords, private keys or readable messages. Bit unsure how on how I could go about implementing this. Iv been looking into PGP, specifically openPGP.js. The main trouble I am having is being able to regenerate the key-pair based off a specific seed. PGP seems to have a random output even if the inputs are the same. Storing the private key in a cookie or in HTML5 storage or something also isnt really an option, too unreliable. Can anyone point me in the right direction?

• How do I securely buy a domain from a private party?

  - by Matt

  I have a domain I want. I found the owners contact information, and negotiated a price. Is there a domain brokerage service out there that would help me with the exchange. I don't want to send off money, and never hear from him again, and I'm sure it's likewise. I've found a lot of sites that carry collections of domains for sale, but I've already found mine, and contacted the owner. I just want a service to facilitate the hand-off. Has anyone used a service like this that they could recommend?

• Migrating Gmail to Office 365

  - by user218699

  Good Morning, I have been setting up Office 365 for my organization. We are currently using Gmail. I have synced our local Active Directory server w/ Office 365, as well as our domains. The problem I am having has to do with migrating mailboxes from Gmail to Office 365. I have been using this article to walk me through the process: http://technet.microsoft.com/en-us/library/dn568114.aspx The issue arises when I begin to sync the mailboxes. Currently I have been trying to sync my own mailbox as a test. The synchronization process has been going on for about 15 hours (for just one mailbox) with no errors or any information given by Office 365, other than the "Syncing" status on the migration page in the Exchange Admin Center. Is syncing a single mailbox supposed to take this long, or have I missed a step? Thanks!

• Hostname confusion (Ubuntu Server 10.04)

  - by letseatfood

  I have just setup Ubuntu 10.04 Server Edition. I have been following this tutorial. The DNS information seems to be setup correctly now, but I am confused about the hostname. Currently it is laughingbuddha.home. That is a name I created. Now, I am mainly not sure how to connect from another computer on my network. I basically want to be able to put PHP files on the server box and then test them via a web browser on my other computer. So, I think I digressed from my first question, but would somebody please help me figure out if the hostname is okay for doing what I need to do? Thank-you!

• Query Performance Degrades with High Number of Logical Reads

  - by electricsk8

  I'm using Confio Ignite8 to derive this information, and monitor waits. I have one query that runs frequently, and I notice that on some days there is an extremely high number of logical reads incurred, +300,000,000 for 91,000 executions. On a good day, the logical reads are much lower, 18,000,000 for 94,000 executions. The execution plan for the query utilizes clustered index seeks, and is below.

Table 'Folder'. Scan count 0, logical reads 4, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Any ideas on how to troubleshoot where these high logical reads come from on certain days, and others nothing?
