  • Windows XP to remote server 2008 R2 shares - awful response times

    - by nick3216
    I have a network infrastructure of Windows XP clients (a mix of XP and 64-bit XP), that are accessing a network share on a Windows 2008 R2 server. Whenever users type the address of a folder into the address bar of Windows Explorer it's as snappy at determining the contents of the current folder and presenting them to you in the address bar as if you're working on a local drive. But if you open one of the subfolders users get the animated red torch and 'Searching for items...' dialog, typically for 45 seconds. Similarly when using the open folder dialog to try and select a subfolder on this share it takes, on average, 45 seconds for the dialog to expand each node and show the subfolders of each node. Also, while the Explorer instance accsesing the network share is running slowly users notice that the performance of all other Explorer windows suffers. So while Explorer is searching for files on the network share they can't switch to another task and navigate around their local drive using Explorer because it's now as slow as a dead dog at accessing anything. Are there any settings we can change which will improve the performance accessing network shares?

  • File gone or altered after MySQL[HY000][2002] error [on hold]

    - by Psyberion
    I'm working on a rather small project, and today I got an SQLSTATE[HY000][2002]:Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' error. After a bit of googling and a few attempts to restart the mysqld service, I gave up and tried rebooting the computer. This did the trick, MySQL was now running fine. I did, however, get a more serious issue: Some files were missing, others were altered. Also, a few posts in the MySQL was gone. It's really strange, it's like the whole project has been reset two or three days, and I have no clue why. Some additional details about this: I save my files after every line of code. I'm religious about this. So I haven't lost the files that way. I was accessing the server via SSH when the error occurred, so I did the programming and the reboot over SSH. The server is a Raspberry Pi, model B, with Raspian on which I run Apache2. I was viewing the site and had an active session when I rebooted the system. The pages I lost did work just before this all happened. The MySQL fault occurred when I tried to add a text NOT NULL column to a table which had entries. Now, the amount of lost work isn't really that much, so I'm not really looking for help recovering the files. The reason I'm posting this is because I wonder how did this happen, and why?

  • Need recommendation: which USB card (PCMCIA) works with external hard drive?

    - by Carl
    I have an HT-Link Cardbus/PCMCIA USB 2.0 2-port card (NEC / 32-bit). My external hard drive w/USB adapter won't work with it, and it will work plugged directly into a USB port on a different laptop. (My USB ports got fried.) I got the card off E-Bay. My MP3 player works plugged into that card. The drivers for the card say "Known limitations: High Speed Isochronus, USB Composite Devices." (No other details provided.) I don't know if the hard drive adapter is "isochronous" or "composite." I've read there are problems with too little power being supplied to the drive. The cable to the drive has two USB plugs on one end, and it doesn't make any difference if I plug both of them into the Cardbus card. What card should I get? I see many different brands on E-Bay. I need one that supplies sufficient power for an external hard drive, and doesn't have any "known limitations" in the way.

  • [deb-5.0] Setup DNS on my server so I can put my IPs in as nameservers of my domain provider

    - by Maurycy Zarzycki
    Basically, my unmanaged VPS provider doesn't supply me with nameserver which I can use with my domain provider to route domain to my server. As I've been told: You need to configure the custom DNS server in your VPS, to setup the custom nameservers. Please refer the following article that would help: http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch18_:_Configuring_DNS Once you configure the nameserver records, please update the domain registrar panel with the custom nameserver details. I tried to follow this guide but it seems to be a bit outdated, and I am complete newb with non-windows systems. I also scanned the google for other articles which could help me with this problem but, alas, nothing I found was of any value for someone who doesn't know this stuff better than his own pockets. I realize this is quite a complex thing to do, but maybe there is some way to automate it? Or a better solution, like a paid service which would act as my nameservers (this one would be interesting), or even hoped to find some company which "rents" people to do stuff like that. Blah, any help will be appreciated, I am at a complete loss here. I can follow some of these steps, but then I soon find that half of the files which are mentioned in the article are somehow not existing anywhere on the server which confuses me, and once we get to the point of creating Zone I can't really decipher all the things written there :/. As per title, my system is Debian 5.0.

  • Windows 7 Upgrade Fail from Home Premium to Ultimate Professional

    - by Michael S-B
    I had a hard drive crash, which meant I had to install a new HDD in my Dell 64-Bit XPS 1350 (lovely computer). I had previously been running Windows 7 Ultimate Professional which I had upgraded from the OEM Win 7 Home Premium by means of a disk I purchased from my university. Using the Recovery disk from Dell I installed Windows 7 Home Premium successfully on the new hard drive, but when I have tried to upgrade via my disk to Ultimate it installs the whole thing, says its complete, but when I reboot, tells me: "This version of Windows could not be installed. Your previous version of Windows has been restored, and you can continue to use it." I've installed the drivers from Dell's driver disk, but still to no avail. I've also used Driver Robot to update all my drivers. I can't find a .dmp file anywhere under C:\$WINDOWS.~BT\Sources but I did find this file under C:\$WINDOWS.~BT\Sources\Panther. setupact.log https://www.dropbox.com/s/yzy7fhkxlzc235y/setupact.log If anyone could please advise me what I need to do to fix Windows so it will upgrade properly, I would greatly appreciate it.

  • Redirect traffic from 127.0.0.1 to 127.0.0.1 on port 53 to port 5300 with iptables

    - by Zagorax
    I'm running a local dns server on port 5300 to develop a software. I need my machine to use that dns but I wasn't able to tell /etc/resolv.conf to check on a different port. I searched a bit on google and I didn't find a solution. I set 127.0.0.1 as nameserver on /etc/resolv.conf. This is my whole /etc/resolv.conf: nameserver 127.0.0.1 Could you please tell me how can I redirect outbound traffic on port 53 to another port? I tried the following but it didn't work: iptables -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to 127.0.0.1:5300 iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 127.0.0.1:5300 Here is the output of iptables -t nat -L -v -n (with suggested rules): Chain PREROUTING (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 REDIRECT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 redir ports 5300 0 0 REDIRECT udp -- * * 0.0.0.0/0 0.0.0.0/0 udp dpt:53 redir ports 5300 Chain POSTROUTING (policy ACCEPT 302 packets, 19213 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 302 packets, 19213 bytes) pkts bytes target prot opt in out source destination

  • Windows Server 2008 (x64): Wont boot past bios page

    - by WebSolProv
    Happy New Year, Since a month or so ago I inherited responsibility for small network administration for my sins. The domain controller (yes there is only one, and yes I know it is best practice to have two even in a small domain setup) went down overnight and I have been trying all day to get it back up and running. Unfortunately this machine also administers our entire ActiveDirectory setup: 1) It goes thru the BIOS without any errors, nothing whatsoever 2) It gets into the “select safe mode, safe mode with networking, normal” etc and if you select either of the safe mode options it loads a few files then reboots. If you select normal it just runs for a bit (doesn’t get to the windows splash screen) and then reboots again. 3) If you select windows repair, it asks for an image to repair too: however it would appear that none was taken that can be used (!!) or one is not being shown. 4) I have tried repairing the boot sector and the boot configuration using Bootrec.exe, both which it says were completed successfully but still it doesn’t work. 5) I have tried swapping the drives into another server to rule out hardware and that didn’t work either so clearly it’s the OS. 6) I have tried running chkdsk which ran fine, and also memory check which was also fine. We do have another machine on the network that was installed as a DC so when we decommission the current infrastructure but when I try and "promote" this to the lead DC then I get “you cannot modify domain or trust information because a PDC emulator cannot be contacted" so I am unable to replicare the ActiveDirectory details. If anyone can think of any direction I should follow it would be greatly appreciated, Thanks, Alex

  • Reporting SQL Vulnerability [migrated]

    - by Ciaran87Bel
    My first post here so i'll hopefully keep it simple. I have just finished building a CMS targeted at a certain industry and built a test site to see how everything works. Anyway I wrote a program to check for sql injection vulnerabilities and the program followed a blog link to an external website. The program discovered that the external site had a massive vulnerability that left it open to practically anyone who could then access every bit of data on their MYSQL Server and run queries etc. The thing is this external site is the brand leader in their industry and do millions upon millions of sales per annum. I have tried contacting them to let them know and even went as far as contacting the company that built their platform but I was pretty much brushed off and haven't heard back from them. Their database would contain the details of hundreds of thousands of customers and all their data. I could easily make myself site admin etc in a few seconds but they won't listen to me even though I have offered to share the vulnerability with them and help in anyway I can. Is there anything else I can do because it is one of the biggest security risks I have ever personally come across. Is there any other steps I should take to report this? Thanks

  • why does my dl380 G3 crank the fan up so high (and how do i stop it?)

    - by smoofra
    I've got a HP DL380 and after I leave it on for a while it decides it needs to run the fans at a much higher speed than it did before. It's really loud and annoying. Is there any way to manually control the fan speed? Or otherwise get it to stop doing that? Thanks. edit: I guess i should have made it clear that this is a bit of a jury-rigged situation. I know the ideal solution is to put the thing in a server room with nice cool air. Unfortunately, that isn't happening. This is the sort of problem that calls for a jury rigged solution like manually setting the fan speed and accepting the fact that it's going to run hot shutting down a CPU (can i do that?) spinning down the disks when they're not in use (is that possible?) solution: Install HP's system health monitoring daemon, hpasmd. I installed it to try to figure out what was going on, and just running it fixed the problem.

  • Windows 7 constantly accessing hard drive [duplicate]

    - by Zohar
    Possible Duplicate: Tool which finds which process is causing the heavy hard drive activity? Did you notice that on Windows 7 (I use 64-bit) the hard drive LED is constantly blinking, which means that the OS is constantly wearing the hard drive by accessing it? It's something related to the system process, and it even occurs in safe mode, so I don't think it's a third party software problem. Has anyone experienced this problem as well, and is it a Windows problem, or caused by something else? Edit: My indexing service is reduced to indexing only the Start Menu. Even if it was set for the whole computer, it would eventually stop; that's not it. My friends also suffer from the same problem. Please answer my first question: have any of you have seen a Windows 7 machine whose hard drive LED is at rest? I'm also trying to track down the offending process using procmon and Resource Monitor, and it actually seems like a system process. It could also be svchost.exe, and I'm not sure which file they are accessing since I see a lot of activity which I can't make sense of. It's loading system DLLs, accessing registry keys, and other nonsense.

  • VMWare server: virtual machine start-up reaches 95% and hangs

    - by Magsol
    This problem cropped up today, after updating my eVGA motherboard's chipset in order to try and fix an unrelated issue. After installing the chipset update (contained SATA and Ethernet drivers), every time I've tried to start my Ubuntu VM, it reaches 95% in the web interface and then just hangs. I'm using VMWare Server 2.0.2, running it within Windows 7 64-bit. I haven't had any issues up until now, and I suspect it has something to do with the chipset update. I've already tried reinstalling VMWare itself, removing the VM from the inventory and re-adding it, and neither has proved successful. I'm also not sure how to kill the VMware server process itself once the start-up hangs; I've only been able to try again by rebooting (as none of the VMWare Services listed kill the server process itself). Any insights? Edit: Uhhh...as an addendum: I have a cron job set up on my Ubuntu VM that runs every 20 minutes. The VM is still listed in the VMWare web interface as at 95% of startup, and the start/stop buttons are still disabled, but the cronjob just ran. I also tested SSH, and I was able to tunnel into the Ubuntu VM as well. Now I'm really confused. Edit #2: I just started a thread on the VMWare Server support forums on this same topic. Hopefully between the two communities, we can come up with an answer: http://communities.vmware.com/thread/251033 Edit #3: In lieu of a specific fix, I've switched over to VirtualBox, and all is working just fine.

  • Perfmon % Processor Time vs. task manager's CPU usage

    - by nat
    I'm new to using Perfmon and performance monitoring in general (so go easy on me please ;) I know that Perfmon doesn't have anything exactly like Task Manager's CPU usage display, but I'm trying to figure out how to monitor user's CPU usage via Perfmon in a similar way, and trying to understand the measurements (or how to convert the numbers to get a similar understanding) For example, if in Task Manager, a particular user is consistently using more than 5% CPU, I would want to contact the user about it. I learn best by example, so here is exactly what I'm trying to do, with a specific example: This is for a 32-bit Dual Quad Core Windows 2003 web server (8 CPUs), there are many web sites on the server, each running within their own application pool/worker process ID. Through other research here I learned of a registry change that I made so that the PID shows up with the w3wp process so I can easily identify the site later by cross-referencing it. I set up a counter with the following settings: Process -> % Processor Time -> all instances Here is an example. Say I'm interested in "black line" user in this graph below, as his process is spiking quite high compared to all the other users: (I wasn't allowed to post the image as I'm a new user on this site.. I've uploaded the image to:) http://i35.tinypic.com/106yn8k.jpg So... using this as an example, I see that they have an AVERAGE % PROCESSOR TIME of 23.264 , and have spiked as high as 103.124 So what exactly does this 23.264 number mean to me? Is it similar to an average of Task Manager's CPU reading for this user? Or, since this server has 8 CPUs, should I divide this number by 8? (23.264/8 = 2.9% AVERAGE CPU LOAD?) Thanks in advance.

  • ActiveDirectoryMembershipProvider and ADAM (or AD LDS) and SetPassword

    - by Iulian
    By the subject line it seems to be a rather broad subject and I need some help here. Basically what I want is to use ActiveDirectoryMembershipProvider with an ADAM instance to authenticate users in an ASP.NET web application. My development environment is a windows 7 machine with an AD LDS instance on it whilst the QA server is a Windows 2003 server with an ADAM instance on it. I have all the required users on both instances plus one with adminsitrator role (CN=Admin,CN=xxx,DC=xxx,C=xx) which I want to use as the connection user. Using connectonProtecton="None" connectionUsername="CN=Admin,CN=xxx,DC=xxx,C=xx" connectionPassword="xxx" I am able to authenticate on both environments (dev & qa). If I change to the connectionProtection to "Secure" I am not able to authenticate anymore; the error I get is "Parser Error Message: Unable to establish secure connection with the server" To me it sounds wrong to use connectionProtection="None" although I found on the net a lot of samples using this setting. Can I use connectionProtection="Secure" to connect to an ADAM instance using an account defined on that instance having Administrator role? What other choices do I have (like using an domain account)? What if my machine where I am to deploy the application is not a part of the domain, will this affect in any way the behavior? I am novice in the respect so I would really appreciate some clear answers or some directions as where to look? Now beside the "signing in" feature of the ActiveDirectoryMembershipProvider I also want to add an extra one, which is setting the password without knowing the old one (something that will be used by a "reset password" feature). So I added a couple of extension methods to the provider, and used System.DirectoryServices classes like DirectoryEntry and the like. When creating a directory entry I use the same credentials provided in web.config for the provider minus the AuthenticationType as I don't know what is right combination of the flags that corresponds to None/Secure. I am able to use Invoke "SetPassword" with ADS_OPTION_PASSWORD_METHOD option as ADS_PASSWORD_ENCODE_CLEAR on my dev machine (w/ AD LDS instance); nevertheless on qa environment (w/ ADAM instance) I am getting an error like "Exception Details: System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred. (Exception from HRESULT: 0x80072020)" I am quite sure it is not about AD LDS vs ADAM but probably another configuration / permission issue. So can anyone help me with some hints on how to use this SetPassword feature? And as a general question what are the best practices when it comes to using ADAM regarding security, programming etc? Thanks in advance Iulian

  • Revisiting .NET, but what should I focus on?

    - by Wayne M
    After about a two-year hiatus, I'm brushing up on my .NET skills to find a .NET job (my previous two positions have very little development, or development using legacy technologies, so apart from a few very minor apps I have not touched .NET in close to two years). I'm aware of things like ASP.NET MVC, and I have previously read on things like NHibernate and DI/IOC, albeit I have yet to use them apart from very trivial "Hello World" type applications. I have a subscription to Rob Conery's Tekpub website and occasionally watch these videos when I have free time. My concern is this: I don't live in a very technical area. I would be surprised if any but the most tech-savvy companies have heard of, let alone use, ASP.NET MVC, NHibernate (or even LINQ/EF), or know about IoC. I would be willing to bet a large sum of money that 95% of the possible jobs I could obtain will use the following: Visual Source Safe, if any VCS at all ASP.NET 2.0 Webforms (3.5 if lucky) Raw ADO.NET on top of a very thin implementation of the Gateway pattern Stored Procedures in the database for most CRUD operations Gratuitous use of code-behind, with a Service layer if I'm lucky If I were extremely lucky, I might find a shop that has heard of ORMs and either uses one, or has wrote their own data abstraction. Also if I were lucky, the company would be using Model-View-Presenter. In light of this I'm not sure what I should focus on learning. Personally, I would prefer to be using the latest stuff - ASP.NET MVC, NHibernate, jQuery, WCF etc. Reality says I should go back to the basics, since it looks like most potential opportunities aren't going to be anywhere near the cutting edge, or anywhere close to it. And, as much as I would like to find a position and start to show the other developers the benefits, in my past experience this has usually resulted in my being fired for "not being a team player" and doing things the bad old way. So, I am curious how you would approach a situation like this? What should I focus on, in order to A) Reaquaint myself with .NET, and B) Prepare myself to obtain a .NET job again that is more than likely going to use techniques that I and most other knowledgeable developers will scoff at?

  • android spinning image

    - by user270811
    hi, i am trying to create two spinning wheels, as in pulleys, so everytime the attached rope moves, the two pulleys will rotate. i have tried two approaches: 1) use Matrix.postRotate within the onDraw() method of the View class, which calls the following: private void drawSpinningWheel(Canvas canvas) { try { canvas.save(); Bitmap bitmapOrg = null; int iDrawable = R.drawable.spinning_button; bitmapOrg = BitmapFactory.decodeResource(getResources(), iDrawable); if(bitmapOrg != null) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 24; int newHeight = 24; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); matrix.postRotate((float) mDegrees++); Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); canvas.drawBitmap(resizedBitmap, matrix, null); } canvas.restore(); } catch(Exception e) { Log.e(TAG + "drawSpinningWheel", e.getMessage()); } } but it seems like the image not only spins but rotates around another axis 2) use SurfaceView and a separate thread, in the run() call this: private void doDraw(Canvas canvas) { // Draw the background image. Operations on the Canvas accumulate // so this is like clearing the screen. canvas.drawBitmap(mBackgroundImage, 0, 0, null); int yTop = mCanvasHeight - ((int) mY + mSpinningWheelImageHeight / 2); int xLeft = (int) mX - mSpinningWheelImageWidth / 2; ... // Draw the ship with its current rotation canvas.save(); canvas.rotate((float) mHeading++, (float) mX, mCanvasHeight - (float) mY); mSpinningWheelImage.setBounds(xLeft, yTop, xLeft + mSpinningWheelImageWidth, yTop + mSpinningWheelImageHeight); mSpinningWheelImage.draw(canvas); canvas.restore(); } i get the spinning to work but i can't add another spinning wheel. i even tried to create another thread for the second spinning wheel, only one shows up. can someone point me in the right direction? thanks.

  • How to serialize parameters in Web Service method

    - by Georgi
    Hi, I have this problem. I have WCF .Net C# web service with this method: public interface IMyService { // TODO: Add your service operations here [OperationContract] ListOfRequests GetListOfRequests(string par1, string par2, string par3, DateTime par4, DateTime par5, string par6, string par7); } public class MyService : IMyService { public ListOfRequests GetListOfRequests(string par1, string par2, string par3, DateTime par4, DateTime par5, string par6, string par7) { // .... web method code here; } } The problem is that when I generate the web service the wsdl schema return this: <xs:element name="GetListOfRequests"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="par1" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par2" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par3" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par4" type="xs:dateTime" /> <xs:element minOccurs="0" name="par5" type="xs:dateTime" /> <xs:element minOccurs="0" name="par6" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par7" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> and I want my parameters to be not null like this: <xs:element name="GetListOfRequests"> <xs:complexType> <xs:sequence> <xs:element minOccurs="1" name="par1" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par2" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par3" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par4" type="xs:dateTime" /> <xs:element minOccurs="1" name="par5" type="xs:dateTime" /> <xs:element minOccurs="1" name="par6" nillable="false" type="xs:string" /> <xs:element minOccurs="0" name="par7" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> How can I serizalize parameters to achieve this?

  • java.lang.Error: "Not enough storage is available to process this command" when generating images

    - by jhericks
    I am running a web application on BEA Weblogic 9.2. Until recently, we were using JDK 1.5.0_04, with JAI 1.1.2_01 and Image IO 1.1. In some circumstances (we never figured out exactly why), when we were processing large images (but not that large - a few MB), the JVM would crash without any error message or stack trace or anything. This didn't happen much in production, but enough to be a nuisance and eventually we were able to reproduce it. We decided to switch to JRockit90 1.5.0_04 and we were no longer able to reproduce the problem in our test environment, so we thought we had it licked. Now, however, after the application server has been up for a while, we start getting the error message, "Not enough storage is available to process this command" during image operations. For example: java.lang.Error: Error starting thread: Not enough storage is available to process this command. at java.lang.Thread.start()V(Unknown Source) at sun.awt.image.ImageFetcher$1.run(ImageFetcher.java:279) at sun.awt.image.ImageFetcher.createFetchers(ImageFetcher.java:272) at sun.awt.image.ImageFetcher.add(ImageFetcher.java:55) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:149) at sun.awt.image.InputStreamImageSource.addConsumer(InputStreamImageSource.java:106) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:144) at sun.awt.image.ImageRepresentation.startProduction(ImageRepresentation.java:647) at sun.awt.image.ImageRepresentation.prepare(ImageRepresentation.java:684) at sun.awt.SunToolkit.prepareImage(SunToolkit.java:734) at java.awt.Component.prepareImage(Component.java:3073) at java.awt.ImageMediaEntry.startLoad(MediaTracker.java:906) at java.awt.MediaEntry.getStatus(MediaTracker.java:851) at java.awt.ImageMediaEntry.getStatus(MediaTracker.java:902) at java.awt.MediaTracker.statusAll(MediaTracker.java:454) at java.awt.MediaTracker.waitForAll(MediaTracker.java:405) at java.awt.MediaTracker.waitForAll(MediaTracker.java:375) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.awt.Image;)Ljava.awt.image.BufferedImage;(Unknown Source) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.net.URL;)Ljava.awt.image.BufferedImage;(Unknown Source) at Resources.Tools.Commands.W$zw(Ljava.lang.ClassLoader;)V(Unknown Source) at Resources.Tools.Commands.getContents()[[Ljava.lang.Object;(Unknown Source) at SfxNET.sfxUtils.SfxResourceBundle.handleGetObject(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at java.util.ResourceBundle.getObject(ResourceBundle.java:320) at SoftwareFX.internal.ChartFX.wxvw.yxWW(Ljava.lang.String;Z)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.wxvw.vxWW(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.CommandBar.YWww(LSoftwareFX.internal.ChartFX.wxvw;IIII)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.YzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;Z)LSoftwareFX.internal.ChartFX.CommandBar;(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.XzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.OnDeserialization(Ljava.lang.Object;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.Zvvz(LSoftwareFX.internal.ChartFX.Base.wzzy;)V(Unknown Source) Has anyone seen something like this before?

  • How to best design a date/geographic proximity query on GAE?

    - by Dane
    Hi all, I'm building a directory for finding athletic tournaments on GAE with web2py and a Flex front end. The user selects a location, a radius, and a maximum date from a set of choices. I have a basic version of this query implemented, but it's inefficient and slow. One way I know I can improve it is by condensing the many individual queries I'm using to assemble the objects into bulk queries. I just learned that was possible. But I'm also thinking about a more extensive redesign that utilizes memcache. The main problem is that I can't query the datastore by location because GAE won't allow multiple numerical comparison statements (<,<=,=,) in one query. I'm already using one for date, and I'd need TWO to check both latitude and longitude, so it's a no go. Currently, my algorithm looks like this: 1.) Query by date and select 2.) Use destination function from geopy's distance module to find the max and min latitude and longitudes for supplied distance 3.) Loop through results and remove all with lat/lng outside max/min 4.) Loop through again and use distance function to check exact distance, because step 2 will include some areas outside the radius. Remove results outside supplied distance (is this 2/3/4 combination inefficent?) 5.) Assemble many-to-many lists and attach to objects (this is where I need to switch to bulk operations) 6.) Return to client Here's my plan for using memcache.. let me know if I'm way out in left field on this as I have no prior experience with memcache or server caching in general. -Keep a list in the cache filled with "geo objects" that represent all my data. These have five properties: latitude, longitude, event_id, event_type (in anticipation of expanding beyond tournaments), and start_date. This list will be sorted by date. -Also keep a dict of pointers in the cache which represent the start and end indices in the cache for all the date ranges my app uses (next week, 2 weeks, month, 3 months, 6 months, year, 2 years). -Have a scheduled task that updates the pointers daily at 12am. -Add new inserts to the cache as well as the datastore; update pointers. Using this design, the algorithm would now look like: 1.) Use pointers to slice off appropriate chunk of list based on supplied date. 2-4.) Same as above algorithm, except with geo objects 5.) Use bulk operation to select full tournaments using remaining geo objects' event_ids 6.) Assemble many-to-manys 7.) Return to client Thoughts on this approach? Many thanks for reading and any advice you can give. -Dane

  • WCF Duplex net.tcp issues on win7

    - by Tom
    We have a WCF service with multiple clients to schedule operations amongst clients. It worked great on XP. Moving to win7, I can only connect a client to the server on the same machine. At this point, I'm thinking it's something to do with IPv6, but I'm stumped as to how to proceed. Client trying to connect to a remote server gives the following exception: System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://10.7.11.14:18297/zetec/Service/SchedulerService/Scheduler. The connection attempt lasted for a time span of 00:00:21.0042014. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297. --- System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297 The service is configured like so: <system.serviceModel> <services> <service name="SchedulerService" behaviorConfiguration="SchedulerServiceBehavior"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost/zetec/Service/SchedulerService"/> </baseAddresses> </host> <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler" binding="netTcpBinding" bindingConfiguration = "ConfigBindingNetTcp" contract="IScheduler" /> <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler" binding="netTcpBinding" bindingConfiguration = "ConfigBindingNetTcp" contract="IProcessingNodeControl" /> </service> </services> <bindings> <netTcpBinding> <binding name = "ConfigBindingNetTcp" portSharingEnabled="True"> <security mode="None"/> </binding> </netTcpBinding > </bindings> <behaviors> <serviceBehaviors> <behavior name="SchedulerServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceThrottling maxConcurrentSessions="100"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> I've checked my firewall about a dozen times, but I guess there could be something I'm missing. Tried disabling windows firewall. I tried changing localhost to my ipv4 address to try to keep away from ipv6, I've tried removing any anti-ipv6 code.

  • html widget communicating with server

    - by Nikita Rybak
    I'm making html widget for websites. Let's say, it will display current stock indexes. In short, arbitrary website owner takes code snippet from me and includes it on his webpage http://website.com/index.html. When arbitrary user opens http://website.com/index.html, my code sends request to my server (provider.com), which performs necessary operations and returns information to user's browser. When response has arrived, user will see relevant stock value on http://website.com/index.html. In index.html service could be called like this <script type="text/javascript" src="provider.com/service.js"> </script> <div id="target_area"></div> <script type="text/javascript"> service.show("target_area", options); </script> Now, the problem is in the same origin policy: I can't just send ajax request from website.com to provided.com and return html to embed in client's webpage. I see several solutions, which I list below, but none quite satisfy me. I wonder, if you could suggest something, especially if you had some relevant experience. 1) iframe, plain and simple. Disadvantage: must have fixed dimensions + stupid scroll bars appearing in some browsers. Can be fixed with javascript, but all this browser-specific tinkering doesn't sound good to me. 2) JSONP. Problem: can't return whole chunk of html, must return only data. Then, on browser side, I'll have to use javascript to embed data into html snippet placed statically in index.html. Doesn't sound nice, because data format is not very simple and may even change later. 3) Use hidden iframe to do ajax requests. A bit tricky, but sounds like a way to go. Well, that's my thoughts on the subject. Are there any better ways? BTW, I tried to check some existing widgets too, but didn't find much useful information. All domain names used in this text are fictional and any resemblance is purely coincidental :)

  • Subversion vision and roadmap

    - by gbjbaanb
    Recently C Michael Pilato of the core subversion team posted a mail to the subversion dev mailing list suggesting a vision and roadmap for the future of Subversion. Naturally, he wanted as much feedback and response as possible which is why I'm posting this here - to elicit some suggestions and contributions from you, the users of Subversion. Any comments are welcome, and I shall feedback a synopsis with a link to this question to the dev mailing list. Similarly, I've created a post on ServerFault to get feedback from the administator side of things too. So, without further ado: Vision The first thing on his "vision statement" is: Subversion has no future as a DVCS tool. Let's just get that out there. At least two very successful such tools exist already, and to squeeze another horse into that race would be a poor investment of energy and talent. There's no need to suggest distributed features for subversion. If you want a DVCS, there should be no ill-feeling if you migrate to Git, Mercurial or Bazaar. As he says, its pointless trying to make SVN like them when they already exist, especially when there are different usage patterns that SVN should be targetting. The vision for Subversion is: Subversion exists to be universally recognized and adopted as an open-source, centralized version control system characterized by its reliability as a safe haven for valuable data; the simplicity of its model and usage; and its ability to support the needs of a wide variety of users and projects, from individuals to large-scale enterprise operations. Roadmap Several ideas were suggested as being "very nice to have" and are offered as the starting point of a future roadmap. These are: Obliterate Shelve/Checkpoint Repository-dictated Configuration Rename Tracking Improved Merging Improved Tree Conflict Handling Enterprise Authentication Mechanisms Forward History Searching Log Message Templates If anyone has suggestions to add, or comments on these, the subversion community would welcome all of them. Community And lastly, there was a call for more people to become involved with Subversion development. As with most OSS projects it can be daunting to join, but there is now a push for more to be done to help. If you feel like you can contribute, please do so.

  • How to make custom WCF error handler return JSON response with non-OK http code?

    - by John
    I'm implementing a RESTful web service using WCF and the WebHttpBinding. Currently I'm working on the error handling logic, implementing a custom error handler (IErrorHandler); the aim is to have it catch any uncaught exceptions thrown by operations and then return a JSON error object (including say an error code and error message - e.g. { "errorCode": 123, "errorMessage": "bla" }) back to the browser user along with an an HTTP code such as BadRequest, InteralServerError or whatever (anything other than 'OK' really). Here is the code I am using inside the ProvideFault method of my error handler: fault = Message.CreateMessage(version, "", errorObject, new DataContractJsonSerializer(typeof(ErrorMessage))); var wbf = new WebBodyFormatMessageProperty(WebContentFormat.Json); fault.Properties.Add(WebBodyFormatMessageProperty.Name, wbf); var rmp = new HttpResponseMessageProperty(); rmp.StatusCode = System.Net.HttpStatusCode.InternalServerError; rmp.Headers.Add(HttpRequestHeader.ContentType, "application/json"); fault.Properties.Add(HttpResponseMessageProperty.Name, rmp); -- This returns with Content-Type: application/json, however the status code is 'OK' instead of 'InternalServerError'. fault = Message.CreateMessage(version, "", errorObject, new DataContractJsonSerializer(typeof(ErrorMessage))); var wbf = new WebBodyFormatMessageProperty(WebContentFormat.Json); fault.Properties.Add(WebBodyFormatMessageProperty.Name, wbf); var rmp = new HttpResponseMessageProperty(); rmp.StatusCode = System.Net.HttpStatusCode.InternalServerError; //rmp.Headers.Add(HttpRequestHeader.ContentType, "application/json"); fault.Properties.Add(HttpResponseMessageProperty.Name, rmp); -- This returns with the correct status code, however the content-type is now XML. fault = Message.CreateMessage(version, "", errorObject, new DataContractJsonSerializer(typeof(ErrorMessage))); var wbf = new WebBodyFormatMessageProperty(WebContentFormat.Json); fault.Properties.Add(WebBodyFormatMessageProperty.Name, wbf); var response = WebOperationContext.Current.OutgoingResponse; response.ContentType = "application/json"; response.StatusCode = HttpStatusCode.InternalServerError; -- This returns with the correct status code and the correct content-type! The problem is that the http body now has the text 'Failed to load source for: http://localhost:7000/bla..' instead of the actual JSON data.. Any ideas? I'm considering using the last approach and just sticking the JSON in the HTTP StatusMessage header field instead of in the body, but this doesn't seem quite as nice?
