  • Frame rate on one of two machines running same code seems to be capped at 60 for no reason

    - by dennmat
    ISSUE I recently moved a project from my laptop to my desktop(machine info below). On my laptop the exact same code displays the fps(and ms/f) correctly. On my desktop it does not. What I mean by this is on the laptop it will display 300 fps(for example) where on my desktop it will show only up to 60. If I add 100 objects to the game on the laptop I'll see my frame rate drop accordingly; the same test on the desktop results in no change and the frames stay at 60. It takes a lot(~300) entities before I'll see a frame drop on the desktop, then it will descend. It seems as though its "theoretical" frames would be 400 or 500 but will never actually get to that and only do 60 until there's too much to handle at 60. This 60 frame cap is coming from no where. I'm not doing any frame limiting myself. It seems like something external is limiting my loop iterations on the desktop, but for the last couple days I've been scratching my head trying to figure out how to debug this. SETUPS Desktop: Visual Studio Express 2012 Windows 7 Ultimate 64-bit Laptop: Visual Studio Express 2010 Windows 7 Ultimate 64-bit The libraries(allegro, box2d) are the same versions on both setups. CODE Main Loop: while(!abort) { frameTime = al_get_time(); if (frameTime - lastTime >= 1.0) { lastFps = fps/(frameTime - lastTime); lastTime = frameTime; avgMspf = cumMspf/fps; cumMspf = 0.0; fps = 0; } /** DRAWING/UPDATE CODE **/ fps++; cumMspf += al_get_time() - frameTime; } Note: There is no blocking code in the loop at any point. Where I'm at My understanding of al_get_time() is that it can return different resolutions depending on the system. However the resolution is never worse than seconds, and the double is represented as [seconds].[finer-resolution] and seeing as I'm only checking for a whole second al_get_time() shouldn't be responsible. My project settings and compiler options are the same. And I promise its the same code on both machines. My googling really didn't help me much, and although technically it's not that big of a deal. I'd really like to figure this out or perhaps have it explained, whichever comes first. Even just an idea of how to go about figuring out possible causes, because I'm out of ideas. Any help at all is greatly appreciated.

  • What components have you built that you are reusing over and over again for your desktop application

    - by Jason
    We are building our internal library of components up, and was wondering what everybody has in their library of reusable components for your organization, for desktop applications. Our list currently includes only a couple of components: Logon, Security and User Group functionality System Tray / Service Framework Component for Internet Communications (to handle proxies, security, etc...) Billing What else do you have, that we should add to our list? If you have reusable web components, save your answers... I will open a different question if this one is successful.

  • Friday Tips #3

    - by Chris Kawalek
    Even though yesterday was Thanksgiving here in the US, we still have a Friday tip for those of you around your computers today. In fact, we have two! The first one came in last week via our #AskOracleVirtualization Twitter hashtag. The tweet has disappeared into the ether now, but we remember the gist, so here it is: Question: Will there be an Oracle Virtual Desktop Client for Android? Answer by our desktop virtualization product development team: We are looking at Android as a supported platform for future releases. Question: How can I make a Sun Ray Client automatically connect to a virtual machine? Answer by Rick Butland, Principal Sales Consultant, Oracle Desktop Virtualization: Someone recently asked how they can assign VM’s to specific Sun Ray Desktop Units (“DTU’s”) without any user interfaction being required, without the “Desktop Selector” being displayed, or any User Directory.  That is, they wanted each Sun Ray to power on and immediately connect to a pre-assigned Solaris VM.   This can be achieved by using “tokens” for user assignment – that is, the tokens found on Smart Cards, DTU’s, or OVDC clients can be used in place of user credentials.  Note, however, that mixing “token-only” assignments and “User Directories” in the same VDI Center won’t work.   Much of this procedure is covered in the documentation, particularly here. But it can useful to have everything in one place, “cookbook-style”:  1. Create the “token-only” directory type: From the VDI administration interface, select:  “Settings”, “Company”, “New”, select the “None” radio button, and click “Next.” Enter a name for the new “Company”, and click “Next”, then “Finish.” 2. Create Desktop Providers, Pools, and VM’s as appropriate. 3. Access the Sun Ray administration interface at http://servername:1660 and login using “root” credentials, and access the token-id’s you wish to use for assignment.  If you’re using DTU tokens rather than Smart Card tokens, these can be found under the “Tokens” tab, and “Search-ing” using the “Currently Used Tokens” tab.  DTU’s can be identified by the prefix “psuedo.”   For example: 4. Copy/paste this token into the VDI administrative interface, by selecting “Users”, “New”, and pasting in the token ID, and click “OK” - for example: 5. Assign the token (DTU) to a desktop, that is, in the VDI Admin Gui, select “Pool”, “Desktop”, select the VM, and click "Assign" and select the token you want, for example: In addition to assigning tokens to desktops, you'll need to bypass the login screen.  To do this, you need to do two things:  1.  Disable VDI client authentication with:  /opt/SUNWvda/sbin/vda settings-setprops -p clientauthentication=Disabled 2. Disable the VDI login screen – to do this,  add a kiosk argument of "-n" to the Sun Ray kiosk arguments screen.   You set this on the Sun Ray administration page - "Advanced", "Kiosk Mode", "Edit", and add the “-n” option to the arguments screen, for example: 3.  Restart both the Sun Ray and VDI services: # /opt/SUNWut/sbin/utstart –c # /opt/SUNWvda/sbin/vda-service restart Remember, if you have a question for us, please post on Twitter with our hashtag (again, it's #AskOracleVirtualization), and we'll try to answer it if we can. See you next time!

  • BizTalk host throttling &ndash; Singleton pattern and High database size

    - by S.E.R.
    Originally posted on: http://geekswithblogs.net/SERivas/archive/2013/06/30/biztalk-host-throttling-ndash-singleton-pattern-and-high-database-size.aspxI have worked for some days around the singleton pattern (for those unfamiliar with it, read this post by Victor Fehlberg) and have come across a few very interesting posts, among which one dealt with performance issues (here, also by Victor Fehlberg). Simply put: if you have an orchestration which implements the singleton pattern, then performances will continuously decrease as the orchestration receives and consumes messages, and that behavior is more obvious when the orchestration never ends (ie : it keeps looping and never terminates or completes). As I experienced the same kind of problem (actually I was alerted by SCOM, which told me that the host was being throttled because of High database size), I thought it would be a good idea to dig a little bit a see what happens deep inside BizTalk and thus understand the reasons for this behavior. NOTE: in this article, I will focus on this High database size throttling condition. I will try and work on the other conditions in some not too distant future… Test conditions The singleton orchestration For the purpose of this study, I have created the following orchestration, which is a very basic implementation of a singleton that piles up incoming messages, then does something else when a certain timeout has been reached without receiving another message: Throttling settings I have two distinct hosts : one that hosts the receive port (basic FILE port) : Ports_ReceiveHostone that hosts the orchestration : ProcessingHost In order to emphasize the throttling mechanism, I have modified the throttling settings for each of these hosts are as follows (all other parameters are set to the default value): [Throttling thresholds] Message count in database: 500 (default value : 50000) Evolution of performance counters when submitting messages Since we are investigating the High database size throttling condition, here are the performance counter that we should take a look at (all of them are in the BizTalk:Message Agent performance object): Database sizeHigh database sizeMessage delivery throttling stateMessage publishing throttling stateMessage delivery delay (ms)Message publishing delay (ms)Message delivery throttling state durationMessage publishing throttling state duration (If you are not used to Perfmon, I strongly recommend that you start using it right now: it is a wonderful tool that allows you to open the hood and see what is going on inside BizTalk – and other systems) Database size It is quite obvious that we will start by watching the database size and high database size counters, just to see when the first reaches the configured threshold (500) and when the second rings the alarm. NOTE : During this test I submitted 600 messages, one message at a time every 10ms to see the evolution of the counters we have previously selected. It might not show very well on this screenshot, but here is what happened: From 15:46:50 to 15:47:50, the database size for the Ports_ReceiveHost host (blue line) kept growing until it reached a maximum of 504.At 15:47:50, the high database size alert fires At first I was surprised by this result: why is it the database size of the receiving host that keeps growing since it is the processing host that piles up messages? Actually, it makes total sense. This counter measures the size of the database queue that is being filled by the host, not consumed. Therefore, the high database size alert is raised on the host that fills the queue: Ports_ReceiveHost. More information is available on the Public MPWiki page. Now, looking at the Message publishing throttling state for the receiving host (green line), we can see that a throttling condition has been reached at 15:47:50: We can also see that the Message publishing delay(ms) (blue line) has begun growing slowly from this point. All of this explains why performances keep decreasing when a singleton keeps processing new messages: the database size grows and when it has exceeded the Message count in database threshold, the host is throttled and the publishing delay keeps increasing. Digging further So, what happens to the database queue then? Is it flushed some day or does it keep growing and growing indefinitely? The real question being: will the host be throttled forever because of this singleton? To answer this question, I set the Message count in database threshold to 20 (this value is very low in order not to wait for too long, otherwise I certainly would have fallen asleep in front of my screen) and I submitted 30 messages. The test was started at 18:26. At 18:56 (ie : exactly 30min later) the throttling was stopped and the database size was divided by 2. 30 min later again, the database size had dropped to almost zero: I guess I’ll have to find some documentation and do some more testing before I sort this out! My guess is that some maintenance job is at work here, though I cannot tell which one Digging even further If we take a look at the Message delivery throttling state counter for the processing host, we can see that this host was also throttled during the submission of the 600 documents: The value for the counter was 1, meaning that Message delivery incoming rate for the host instance exceeds the Message delivery outgoing rate * the specified Rate overdrive factor (percent) value. We will see this another day… :) A last word Let’s end this article with a warning: DO NOT CHANGE THE THROTTLING SETTINGS LIGHTLY! The temptation can be great to just bypass throttling by setting very high values for each parameter (or zero in some cases, which simply disables throttling). Nevertheless, always keep in mind that this mechanism is here for a very good reason: prevent your BizTalk infrastructure from exploding!! So whatever you do with those settings, do a lot of testing and benchmarking!

  • Plan your SharePoint 2010 Content Type Hub carefully

    - by Wayne
    Currently setting up a new environment on SharePoint 2010 (which was made available for download yesterday if anyone missed that :-). One of the new features of SharePoint 2010 is to set up a Content Type Hub (which is a part of the Metadata Service Application), which is a hub for all Content Types that other Site Collections can subscribe to. That is you only need to manage your content types in one location. Setting up the Content Type Hub is not that difficult but you must make it very careful to avoid a lot of work and troubleshooting. Here is a short tutorial with a few tips and tricks to make it easy for you to get started. Determine location of Content Type Hub First of all you need to decide in which Site Collection to place your Content Type Hub; in the root site collection or a specific one. I think using a specific Site Collection that only acts as a Content Type Hub is the best way, there are no best practice as of now. So I create a new Site Collection, at for instance http://server/sites/CTH/. The top-level site of this site collection should be for instance a Team Site. You cannot use Blank Site by default, which would have been the best option IMHO, since that site does not have the Taxonomy feature stapled upon it (check the TaxonomyFeatureStapler feature for which site templates that can be used). Configure Managed Metadata Service Application Next you need to create your Managed Metadata Service Application or configure the existing one, Central Administration > Application Management > Manage Service Applications. Select the Managed Metadata service application and click Properties if you already have created it. In the bottom of the dialog window when you are creating the service application or when you are editing the properties is a section to fill in the Content Type Hub. In this text box fill in the URL of the Content Type Hub. It is essential that you have decided where your Content Type Hub will reside, since once this is set you cannot change it. The only way to change it is to rebuild the whole managed metadata service application! Also make sure that you enter the URL correctly. I did copy and paste the URL once and got the /default.aspx in the URL which funked the whole service up. Make sure that you only use the URL to the Site Collection of the hub. Now you have to set up so that other Site Collections can consume the content types from the hub. This is done by selecting the connection for the managed metadata service application and clicking properties. A new dialog window opens and there you need to click the Consumes content types from the Content Type Gallery at nnnn. Now you are free to syndicate your Content Types from the Hub. Publish Content Types To publish a Content Type from the hub you need to go to Site Settings > Content Types and select the content type that you would like to publish. Then select Manage publishing for this content type. This takes you to a page from where you can Publish, Unpublish or Republish the content type. Once the content type is published it can take up to an hour for the subscribing Site Collections to get it. This is controlled by the Content Type Subscriber job that is scheduled to run once an hour. To speed up your publishing just go to Central Administration > Monitoring > Review Job Definitions > Content Type Subscriber and click Run now and you content type is very soon available for use. Published Content Type status You can check the status of the content type publishing in your destination site collections by selecting Site Settings > Content Type Publishing. From here you can force a refresh of all subscribed content types, see which ones that are subscribed and finally check the publishing error log. This error log is very useful for detecting errors during the publishing. For instance if you use any features such as ratings, metadata, document ids in your content type hub and your destination site collection does not have those features available this will be reported here.

  • User Productivity Kit - Powerful Packages (Part 2)

    - by [email protected]
    In my first post on packages I described what a package is and how it can be used. I also started explaining some of the considerations that should be taken into account when determining how to arrange your packages. The first is when the files are interrelated and depend on one another such as an HTML file and it's graphics. A second consideration is how the files are used in your outlines. Let's say you're using a dozen Word doc files. You could place them all in a single package or put each Word doc file in a separate package but what's the right thing to do? There are several factors that will influence your decision. To understand the first, let me explain a function of UPK publishing. Take an outline in UPK that has an attachment (concept, frame link, or hyperlink) that points to a file in a package. When you publish this outline, the publishing engine will determine that there is a link to a file in the package and copy the contents of the package to the publishing destination directory. This is done to ensure that any interrelated files are kept together. For the situation where you have an HTML file with links to number of graphics files, this is a good thing. If, however, the package has a dozen unrelated Word doc files and you link to only one of them, all dozen Word documents will be copied to the publishing destination directory.  Whether or not this is a good thing is dependent on two things. First, are all of the files in the package used in the outline that you're publishing? Take an outline that includes links to all of the Word documents in that dozen document package I described earlier. For this situation, you may choose to keep all the files in a single package for convenience. A second consideration is how your organization leverages reuse in UPK. In this context, I'm referring to the link style of reuse such as when you link to the same topic from multiple UPK outlines and changes to the topic appear in both places. Take an example where you have the earlier mentioned dozen Word document package and an outline with a dozen topics in it. Each topic has an attachment pointing to one of the Word documents in the package (frame link, concept, etc.) If you're only publishing this outline, the single package probably works fine but what if you're reusing one of these topics in another outline? As I explained earlier, linking to one file in the package will result in all files in the package being copied to your published output. In this example, linking to one topic in the first outline will result in all dozen Word documents being copied to the published output. This may result in files in the output that you don't want there for business or size reasons. This is a situation in which you should consider placing each of the Word documents in it's own separate package. With each document in it's own package, that link to a single document will result in only that single package and single Word document being copied to the published output. In my last post I had described that packages are documents in the UPK library. When using the multi-user version of the UPK Developer you can leverage standard library capabilities for managing the files in these packages during the development process - capabilities such as check in / check out, history, etc. When structuring your packages take into consideration how the authors are going to be adding, modifying and deleting files from the packages. A single package is a single document in the UPK library. Like any other document in the library, a single user can check out the package and edit it at a time. If you have a large number of files in a single package and these must be modified by many users, you need to consider whether this will cause problems as multiple users compete to update the same package. If the files don't depend on each other consider placing the files in separate packages to reduce contention. I hope you've enjoyed these two posts on how you can leverage the power of packages in your content. In summary, consider the following when structuring your packages: Is the asset a single, standalone file or a set of files that depend on each other? Will all the files always be used together in a single outline or may only some of the files be needed based on how the content is reused across multiple outlines? Will multiple developers need to update the files in a single package or should you break it into multiple packages to reduce contention when checking out the document? We'd like to hear from you on how you're using packages in your content. Please add your comments below! Thank you and I hope these two posts have given you additional insights into how to use packages in your content and structure them for efficient use.

  • Prevent anonymous access to form and application pages in SharePoint 2010

    - by shehan
    When you create a Publishing site that has anonymous access enabled, you will notice that anonymous users will not be able to access pages that reside in the “_layouts” virtual directory (e.g. http://siteX/_layouts/viewlsts.aspx). This is because the publishing infrastructure activates a hidden feature that prevents anonymous users from accessing these types of pages. However, if you were to create a site collection based of  Blank Site Template, you would notice that these pages are accessible by anonymous users. The fix is quite simple. There is a hidden feature that you would need to manually activate via stsadm. The feature is called “ViewFormPagesLockDown” (and is available in the Features folders in the 14 hive) To activate it: stsadm -o activatefeature -filename ViewFormPagesLockDown\feature.xml -url http://ServerName Once activated anonymous users will be promoted to enter credentials when they try to access form and application pages. The feature can also be deactivated for publishing sites that have it automatically turned on.   Technorati Tags: SharePoint 2010,anonymous,lockdown,pages,security

  • Some Early Considerations

    - by Chris Massey
    Following on from my previous post, I want to say "thank you" to everyone who has got in touch and got involved – you are pioneers! An update on where we are right now: paper prototypes v1 To be more specific, we’ve picked two of the ideas that seem to have more pros than cons, turned them into Balsamiq mockups, and are getting them fleshed out with realistic content. We’ll initially make these available to the aforementioned pioneers (thank you again), roll in the feedback, and then open up to get more data on what works and what doesn’t. If you’ve got any questions about this (or what we’re working on right now), feel free to ask me in the comments below. I’ve had a few people express an interest in the process we’re going through, and I’m more than happy to share details more frequently as we go along – not least because you, dear reader, will help us stay on target and create something Good. To start with, here’s a quick flashback to bring you all up to speed. A Brief Retrospective As you may already know, we’re creating a new publishing asset specifically focused on providing great content for web developers. We don’t yet know exactly what this thing will look like, or exactly how it will work, but we know we want to create something that is useful different. For my part, I’m seriously excited at the prospect of building a genuinely digital publishing system (as opposed to what most publishing is these days, which is print-style publishing which just happens to be on the web). The main challenge at this point is working out our build-measure-assess loop to speed up our experimental turn-around, and that’ll get better as we run more trials. Of course, there are a few things we’ve been pondering at this early conceptual stage: Do we publishing about heterogeneous technology stacks from day 1, or do we start with ASP.NET (which we’re familiar with) & branch out later? There are challenges with either approach. What publishing "modes" are already being well-handled? For example, the likes of Pluralsight, TekPub, and Treehouse have pretty much nailed video training (debate about price, if you like), and unless we think we can do it faster / better / cheaper (unlikely, for the record), we should leave them to it. Where should we base whatever we create? Should we create a completely new asset under a new name, graft something onto Simple-Talk (like the labs), or just build something directly into Simple-Talk? It sounds trivial, but it does have at least some impact on infrastructure and what how we manage the different types of content we (will) have. Are there any obvious problems or niches that we think could address really well, or should we just throw ideas out and see what readers respond to? What kind of users do we want to provide for? This actually deserves a little bit of unpacking… Why are you here? We currently divide readers into (broadly) the categories: Category 1: I know nothing about X, and I’d like to learn about it. Category 2: I know something about X, but I’d like to learn how to do something specific with it. Category 3: Ah man, I have a problem with X, and I need to fix it now. Now that I think about it, I might also include a 4th class of reader: Category 4: I’m looking for something interesting to engage my brain. These are clearly task-based categorizations, and depending on which task you’re performing when you arrive here, you’re going to need different types of content, or will have specific discovery needs. One of the questions that’s at the back of my mind whenever I consider a new idea is “How many of the categories will this satisfy?” As an example, typical video training is very well suited to categories 1, 2, and 4. StackOverflow is very well suited to category 3, and serves as a sign-posting system to the rest. Clearly it’s not necessary to satisfy every category need to be useful and popular, but being aware of what behavior readers might be exhibiting when they arrive will help us tune our ideas appropriately. < / Flashback > We don’t have clean answers to most of these considerations – they’re things we’re aware of, and each idea we look at is going to be best suited to a different mix of the options I’ve described. Our first experimental loop will be coming full circle in the next few days, so we should start to see how the different possibilities vary between ideas. Free to chime in with questions and suggestions about anything I’ve just brain-dumped, or at any stage as we go along. If you see anything that intrigued or enrages you, or just have an idea you’d like to share, I’d love to hear from you.

  • Prevent Cisco VPN from interrupting home networking

    - by jkohlhepp
    I just got a new laptop, and for the most part have left its settings alone. Today I was trying to get some sharing going between my desktop and the laptop. Both machines are connected to the same wireless network and both machines consider that network to be a Home network. Both are running Win7 Home Premium. It seems like my laptop is aware of my desktop on the network. It can ping it by IP or by computer name. When I go to Network from the laptop, I can see the desktop in the list of computers. However, my desktop cannot ping the laptop, nor can it see it within Network. My desktop has a Homegroup set up, but my laptop says "There is currently no homegroup on the network". I do have network discovery turned on for both machines. Why can my desktop not "talk" to my laptop but it works the other way around? Update: Disabling the Windows Firewall on the laptop somewhat fixes the problem. With it disabled, my desktop can ping my laptop, but still my laptop can't see the homegroup. Also, it can ping via hostname, which resolves to IPv6, but can't ping via the IPv4 address. Obviously I'd rather not leave my firewall disabled, so I need a more specific fix. Update 2: Aha! It is the Cisco VPN software I was running to connect to work computers. Once I disconnected and exited from that, the two PCs seemed to be talking normally and the homegroup was visible to the laptop. So now my question has morphed: how can I prevent Cisco VPN from interrupting my home networking?

  • can't ssh within LAN, but can connect from outside

    - by Patrick B.
    A strange issue: I have a desktop running Ubuntu 10.04 behind a Netgear WNR1000 router performing NAT. I would like to be able to ssh into the desktop from my laptop (running Windows 7 and Cygwin). When at home, both the desktop and the laptop are connected by wireless (the desktop is in a different room from the router). sshd seems to be running fine, since ssh localhost from the desktop works without trouble. Also, ssh my.ip.address from my laptop when it is not behind the router works fine (I am forwarding port 22 on the router to my desktop). However, ssh same.ip.address from within the LAN fails with "Connection refused". ssh 192.168.local.ip.address fails with a different message, "Connection timed out". I can connect if I first ssh to a machine outside the LAN. So far I haven't found anything with Google because with the search terms that seem like they would be relevant, the vast majority of people have the opposite problem - i.e., they can't connect from outside the LAN but can connect within it. I can port forward through a remote server when I'm at home, but this seems like a totally absurd way to connect two computers on the same home LAN. I have already tried stopping and starting sshd on the desktop. Any thoughts?

  • Using a Linksys Wireless- G Broadband Router for a Wireless Antenna/Adapter?

    - by Alex
    (Warning: I'm not too computer-smart). Just moved fm a home where I used ATT DSL to a home w/ Comcast Cable for internet. Old home had the DSL ethernet wired to my only desktop w/ a 2Wire router for my wireless signal for the laptops. In the new home the signal comes fm cable via a Netgear(300) wireless router (remotely located) & works fine for my laptops. After searching with the network software, my desktop (can't be ethernet wired cuz of location) detects no wireless signal. Desktop is a 2 yr old HP p6311f Pavilion (Windows 7). Can't seem to detect any wireless hardware (ant/adaptr). Maybe I don't have the ability & need to buy a USB wireless antenna? Would the Pavilion come w/ wireless capability out of the box, maybe something inside the tower? No antenna on back. I happen to have a Linksys Wireless router which I plugged in to the desktop (trying both internet & shared ports) & noticed signal action on the router front panel. No internet on desktop though. Can I use this as an antenna for the desktop? Thanks & sorry if my solution is an easy one I'm just missing. Just want internet on the desktop.

  • Administrative shares in Windows 7 Pro not visible

    - by Chris Tybur
    My desktop machine has a clean install of Windows 7 Professional. For some reason the standard administrative shares Admin$, C$, D$, etc are not visible, either in Computer Management - Shared Folders - Shares or via net share. I also have a laptop with a clean install of Windows 7 Professional, and I can see the admin shares in both places. As such, I can map to \\laptop\c$ from the desktop, but I can't map to \\desktop\c$ from the laptop. I pretty much took the defaults during the Windows 7 installations. I've tried adding LocalAccountTokenFilterPolicy to the registry on the desktop, but that didn't work. On the desktop I've also disabled UAC, turned off Windows firewall, removed it from a homegroup, made sure file and printer sharing is turned on, but nothing has worked. There is some subtle difference between the two machines that I can't seem to find. I'm logging into both machines using a local account that is in the Administrators group. Both accounts have the same name and password. I really don't want to have to create a new share for the desktop's C drive, especially since C$ is visible and working on the laptop and therefore I should be able to make it work on the desktop. Any idea why the admin shares would work on one machine and not another? Or why LocalAccountTokenFilterPolicy would fail?

  • Western Digital HDD disappears and reappears in BIOS

    - by tbkn23
    I know many people asked about similar problems, but I have a very specific case where I can't understand what's going on... I have a 3TB Western Digital Caviar Green disk connected in my Desktop, that also has a seagate 1.5TB disk and 2 SSD drives (OCZ and Sandisk). After working fine for quite some time (probably more than a year), suddenly my Caviar Green drive disappeared from windows. I checked the BIOS, and it wasn't there either. I opened my PC, played with the connectors, power, etc, but nothing helped. Even tried switching connectors with those of the 1.5TB disk, and nothing changed, the 1.5TB seagate was there, but the 3TB WD was not. Ok, now for the strange part. I have another desktop at home, so I took out my 3TB drive, connected it there, and it worked fine! I copied the most important files out of it, and then made another attempt in the original desktop. Surprise! It now appeared in the BIOS and worked fine! I even ran the SMART test with the WD tools and it said everything was intact. It doesn't end here. After leaving it overnight in the original desktop, it disappeared again in the morning. I repeated the entire process, connecting it to the second desktop, and there it is again working fine. Now for my question... Whats going on? The disk seems to be appearing on/off in my original Desktop, while other drives there work fine. SMART test says the disk is fine. Any ideas? Is the disk defective and should be replaced? Or maybe there's a problem with the controller in the desktop? I'm using a Gigabyte GA-880GA-UD3H motherboard and tried connecting the drive to both bridges (SATA2 and SATA3 bridges). Thanks EDIT: Power options are set never to turn off hard drives:

  • How to use Windows login for single-sign-on and for Active Directory entries for Desktop Java applic

    - by Touko
    I'd like to have my desktop Java application to have single sign on related to Active Directory users. In two steps, I'd like to : Be sure that the particular user has logged in to Windows with some user entry. Check out some setup information for that user from the Active Directory With http://stackoverflow.com/questions/31394/java-programatic-way-to-determine-current-windows-user I can get the name of the current Windows user but can I rely to that? I think the System.getProperty("user.name") won't be secure enough? ("user.name" seems to be got from environment variables, so I can't rely on that, I think?) Question http://stackoverflow.com/questions/390150/authenticating-against-active-directory-with-java-on-linux provides me the authentication for given name+pass but I'd like to authenticate based on the Windows logon? For the Active Directory access, the LDAP would probably be the choise? I'm not totally sure if I'm asking the right questions but hopefully somebody has some ideas to forward me on.

  • Which language/framework to use for this desktop internet application?

    - by Karsten
    I'd like to experiment with a new language/framework to work on some desktop tools for myself, which will do tasks related to internet services. I.e. i'd like to to monitor some of my servers for http or icmp response, also parse xml responses. I have experience with php, lua, mysql, and basic knowledge of java and c++. I'm also interested in exploring multithreading for this, background tasks and a responsive gui do need that as i have read. Being a private project, i certainly want to learn something new, but i don't have that much free time. The question for you would be which language and what framework to choose that could help me with this tasks: lightweight + fast gui (windows only would be ok, platform-independent even better) network/socket support, html module would be appreciated htmlview support xml "parsing" support (xpath or something like the phpish DOMDocument class) threading support Free software would be nice, but paying some bucks won't hurt me if it really helps the case.
