Which itch does a gravatar scratch?

- by WizardOfOdds

This is a very serious question: I've seen lots of threads here about gravatars but I couldn't find and answer to this question: what computer identification/authentication (?) problem, if any, are gravatars supposed to solve? Neither the Wikipedia entry nor the official website are very useful. The official website mentions a "globally unique" picture. Unique in what sense? As far as I can see it's only the hash that is unique: two persons can have two pictures looking very similar if not identical. Note that this question is not about which problems do gravatars unarguably cause (like leaking 10% of the stackoverflow.com accounts email addresses like discussed here : "gravatars can leak email adresses" ) but about which authentication (?) problems, if any, are gravatars supposed to solve? Is the goal just to have a cool/funny/cute icon and save bandwith by having it stored on a remote website or is there more to it, like serving a real authentication purpose which I'd be completely missing? Note that I've got nothing against them and find them rather cool, but I'm just having a hard time figuring out what their purpose is and if I should care or not about them in the webapps I'm developping.

Hi all, I am experiencing problems creating a connection pool in glassfish v3, just for reference i am using the Java EE glassfish bundle. my enviroment vars are as follows Url:

FindByIdentity in System.DirectoryServices.AccountManagment Memory Issues

- by MVC Fanatic

I'm working on an active directory managament application. In addition to the typical Create A New User, Enable/Disable an account, reset my password etc. it also managages application permissions for all of the clients web applications. Application management is handled by thousands of AD groups such as which are built from 3 letter codes for the application, section and site, there are also hundreds of AD groups which determine which applications and locations a coordinator can grant rights to. All of these groups in turn belong to other groups so I typically filter the groups list with the MemberOf property to find the groups that a user directly belongs to (or everyone has rights to do everything). I've made extensive use of the System.DirectoryServices.AccountManagment namespace using the FindByIdentity method in 31 places throughout the application. This method calls a private method FindPrincipalByIdentRefHelper on the internal ADStoreCtx class. A SearchResultCollection is created but not disposed so eventually typically once or twice a day the web server runs out of memory and all of the applications on the web server stop responsing until iis is reset because the resources used by the com objects aren't ever relased. There are places where I fall back to the underlying directory objects, but there are lot of places where I'm using the properties on the Principal - it's a vast improvement over using the esoteric ad property names in the .Net 2.0 Directory services code. I've contacted microsoft about the problem and it's been fixed in .Net 4.0 but they don't currently have plans to fix it in 3.5 unless there is intrest in the community about it. I only found information about it in a couple of places the MDSN documentation in the community content state's there is a memory leak at the bottom (guess I should have read that before using the the method) http://msdn.microsoft.com/en-us/library/bb345628.aspx And the class in question is internal and doesn't expose SearchResultsCollection outside the offending method so I can't get at the results to dispose them or inherit from the class and override the method. So my questions are Has anyone else encountered this problem? If so were you able to work around it? Do I have any option besides rewriting the application not using any of the .Net 3.5 active directory code? Thanks

Launch an arbitrary application with a specific icon

- by Camilo Martin

I'm thinking about customizing my Windows 7's application icons, so that they all follow a specific theme (Token-like icons). This would involve using Resource Hacker (or similar) to patch each .exe. Not only this would be tiresome, but also it would require doing it again at each update of each application (nevermind that some could break just because it was tampered with). Instead, is there any way to launch an application with a specific icon? Ideally it would be something from the command-line (so I can make a shortcut), like this: launchwithicon.exe --app C:\myapp.exe --icon C:\myicon.ico Note that while it is possible to do something similar by setting the taskbar to "always combine, hide labels", I do not like this approach and instead am looking for something that works without combining the taskbar icons.

CPU & Memory Usage Log & Performance

- by wittythotha

I want to have an idea of the amount of CPU and memory that is being used. I have a website hosted using IIS, and have clients connecting to it. I want to find out the amount of load that the CPU, RAM and the network has when multiple clients connect. I tried out using tools like Fiddler, the inbuilt Resource Manager, and also some other applications I found on the internet. I just want to keep track of all these data in a file, so I can plot out a graph and find out how the CPU, etc. is performing. I read a few other posts, but didn't find anything that solves the problem. Is there good CPU / Memory Logging tool available, just to plot a graph of the usage, etc.? EDIT : I want to know of some tool that can save the performance details in a log file, so that I can use it to plot a graph, etc.

Windows and Linux applications to show cumulative uploads/downloads for each app, at a glance

- by jontyc

I've read few quite a few other threads on SU, but they have been focused on instantaneous/average bandwidths (B/sec) rather than cumulative download/upload totals for a period. Either that or they don't drill down to application level. Resource Monitor in Windows 7 only shows bandwidth. I've just been trying NetLimiter and whereas it can show total uploaded/downloaded, it's a case of having one stats window open per application, as opposed to a table showing all applications at once. Looking for applications for both Windows and Linux (Ubuntu), but they don't need to be the same.

Is there a way to capture the "network user name" and the "host name" during a "login failed" alert

- by Jorge Rivera

I am a SQL Server 7 DBA and I would like to "improve" the default "Login failed" alert that brings SQL 7. I need a way to know what "user" (network user name) was trying to connect to the server (not only the SQL user account) and I would like to know from where the user was trying to connect (the hostname). Does someone know if this is possible? Using the SQL Profiler is not the best way since is a resource consuming task. Would be a way to setup an alert for doing this? Thanks in advance.

What's the difference between a Table and a Named Range in Excel 2007?

- by technomalogical

Can someone explain the difference between Tables and Named Ranges in Excel 2007? It seems that in addition to having the features of Named Ranges, they're somehow marked as Tables which gives them special formatting & filtering options in the ribbon. Other questions: Can I treat a table as a named range? Does a named range provide me any functionality not offered by a table, and vice versa? Should I use one over the other (assuming that consumers of the spreadsheet are using Excel 2007 or higher)? Google has not been helpful (excel difference between named range and table and excel 2007 difference between named range and table) and I've found one resource describing table functionality, but no reference to named ranges.

Scripting a Windows 2008 Cluster from Windows 2003

- by glancep

Our current environment is all Windows 2003. When we migrate a new version of our service to the cluster, we first stop the service with a command like: cluster.exe <clusterName> resource "<serviceName>" /offline We do similarly after the migrate to bring the service back online. Now, we are upgrading our environment to new Windows 2008 servers. However, our build/migrate machine will remain Windows 2003. When issuing the same command from Windwos 2003 to Windows 2008, we get: System error 1722 has occurred (0x000006ba). The RPC server is unavailable. We need to be able to remotely administer a Windows 2008 cluster from a Windows 2003 server in an automated fashion (such as the command-line cluster.exe utility). Is this possible? Thanks, Gideon

deleting HBITMAP causes an access violation at runtime.

- by Oliver

Hi, I have the following code to take a screenshot of a window, and get the colour of a specific pixel in it: void ProcessScreenshot(HWND hwnd){ HDC WinDC; HDC CopyDC; HBITMAP hBitmap; RECT rt; GetClientRect (hwnd, &rt); WinDC = GetDC (hwnd); CopyDC = CreateCompatibleDC (WinDC); //Create a bitmap compatible with the DC hBitmap = CreateCompatibleBitmap (WinDC, rt.right - rt.left, //width rt.bottom - rt.top);//height SelectObject (CopyDC, hBitmap); BitBlt (CopyDC, //destination 0,0, rt.right - rt.left, //width rt.bottom - rt.top, //height WinDC, //source 0, 0, SRCCOPY); COLORREF col = ::GetPixel(CopyDC,145,293); // Do some stuff with the pixel colour.... delete hBitmap; ReleaseDC(hwnd, WinDC); ReleaseDC(hwnd, CopyDC); } the line 'delete hBitmap;' causes a runtime error: an access violation. I guess I can't just delete it like that? Because bitmaps take up a lot of space, if I don't get rid of it I will end up with a huge memory leak. My question is: Does releasing the DC the HBITMAP is from deal with this, or does it stick around even after I have released the DC? If the later is the case, how do I correctly get rid of the HBITMAP?

Unable to logoff, disconnect, or reset terminal server user in production environment

- by l0c0b0x

I'm looking for some ideas on how to disconnect, logoff, or reset a user's session in a 2008 Terminal Server (unable to login as the user either as it is completely locked-up). This is a production environment, so rebooting the server or doing something system-wide is out of the question for now. Any Powershell tricks to help us with this? We've tried killing the session's processes too, directly from the same terminal server (from the task manager, Terminal Services Manager and the Resource Monitor) with no results. Help!

Where can I compare monitors with a given VESA mount?

- by Dan Rasmussen

I am looking into purchasing a dual-monitor setup, and need to purchase two monitors with VESA MIS-D mounts. My only problem is that that information doesn't seem to be readily available on most shopping websites. Neither Amazon nor Newegg seem to have the information searchable or filterable. I could shop for monitors, then Google around to see if they support VESA MIS-D, but is there a better way? Is there a resource (not necessarily a store - once I find a monitor I can shop elsewhere) where I can browse a variety of monitor specs and reviews while only looking at monitors with a certain VESA mount?

Problems with shutting down JBoss in Eclipse if I change JNDI port

Delphi 2009: How do I prevent network application from leaking critical section?

As part of Vista certification, Microsoft wants to make sure that an application exits without holding on to a lock (critical section): TEST CASE 31. Verify application does not break into a debugger with the specified AppVerifier checks (Req:3.2) As it turns out, network applications built using Delphi 2009 does break into the debugger, which displays unhelpful message as follows: (1214.1f10): Break instruction exception - code 80000003 (first chance) eax=00000001 ebx=07b64ff8 ecx=a6450000 edx=0007e578 esi=0017f7e0 edi=80000003 eip=77280004 esp=0017f780 ebp=0017f7ac iopl=0 nv up ei pl zr na pe nc cs=0023 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00000246 *** ERROR: Symbol file could not be found.

BES 5.0 and MAPI calls to exchange system

- by nysingh

We have been using BES 4.1(5) for a while now and it has been a resource hog on exchange due to high number of MAPI calls. I have heard that BES 5.0 is even worse. the comparison i heard is that BES 4.1 is makes MAPI calls equal to 5 outlook clients per BB user and BES 5.0 makes MAPI calls equal to 10 outlook clients per BB user. can someone confirm if it is true? is BES 5.0 is really that bad in MAPI calls and for exchange performance. ? thanks

What causes winsock 10055 errors? How should I troubleshoot?

- by Tom Kerr

I'm investigating some issues with winsock 10055 errors on a chain of custom applications (some of which we control, some not) and was hoping to get some advice on techniques to troubleshoot the problem. No buffer space available. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. From research, non-paged pool and ports seem to be the only resources which can cause this error. Is there another resource which might cause 10055 errors? Currently, we have perfmon counters setup on the applications and non-paged pool usage looks low in most circumstances. Open TCP connections looks low and I am unaware of another way to monitor ports. Since it only happens in production, we are unable to use more invasive counters. Is there some other tool or procedure you would recommend to diagnose which application is causing the issue?

Options to optimize lotus notes 8.5.X

- by Jakub

Has anyone found actually useful optimization methods for the bulky, fat, eclipse giant, nuissance that is Lotus Notes 8.5? I want it to be fast, and not eat up system resources like crazy while I run it ALL day (as it is my company's corporate mail / cal / scheduling solution). I've tried various hacks for the JVM heap size (if I recall correctly). None really bring a performance improvement. I have a dual core cpu, if that helps (I tried going the route of optimizing JAVA for 2 cores in hopes it would work, but seen no speed improvement). Notes is just sooo bloated, anyone have any suggestions to optimize/mod this thing so it is more responsive and less of a resource hog. Note: I don't want to switch to the web version, or the standard stripped down versions, I am aware of those, I just cannot since we don't run those internally for the company.

Where should I go to learn about networking? [closed]

- by Ollie Saunders

I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

All of ESX4 hosts not responding after rebooting vCenter server

Hello I'm constructing 5ESX+a vCenter serv. I'm testing FT on the system. Today vCenter OS (W2008) demanded system reboot. After rebooting vCenter Serv. All of ESX hosts have alert icon. end indicate "not responding" I tried to connect ESX (version 4) hosts to vCenter again. Once they came back normally, but after few seconds ,They turned red again. All of them have ping connection to vCenter serv. There are no red messages in Tusks and events. Two messages are found in Summary of Cluster ·There aren't sufficient resource for HA failover. ·Can't contact primary HA agent. I'm also not able to reset FT configuration because all of VMS aren't accessed from vCenter What should I do?

SSLCipherSuite - disable weak encryption, cbc cipher and md5 based algorithm

- by John

A developer recently ran a PCI Scan with TripWire against our LAMP server. They identified several issues and instructed the following to correct the issues: Problem: SSL Server Supports Weak Encryption for SSLv3, TLSv1, Solution: Add the following rule to httpd.conf SSLCipherSuite ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM Problem: SSL Server Supports CBC Ciphers for SSLv3, TLSv1 Solution: Disable any cipher suites using CBC ciphers Problem: SSL Server Supports Weak MAC Algorithm for SSLv3, TLSv1 Solution: Disable any cipher suites using MD5 based MAC algorithms I tried searching google for a comprehensive tutorial on how to construct an SSLCipherSuite directive to meet my requirements, but I didn't find anything I could understand. I see examples of SSLCipherSuite directives, but I need an explanation on what each component of the directive does. So even in the directive SSLCipherSuite ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM, I dont understand for example what the !LOW means. Can someone either a) tell me the SSLCipherSuite directive that will meet my needs or b) show me a resource that clearly explains each segment of a SSLCipherSuite is and how to construct one?

Setting up SSL on Glassfish V2 or V3

- by javanix

My employer recently purchased a Trustwave SSL certificate. Trustwave advertises support on their website, but they don't give an installation guide like they do for their other servers at all, and I am having a difficult time getting it configured correctly with GlassFish. I found this http://blogs.sun.com/enterprisetechtips/entry/using_ssl_with_glassfish_v2 blog post that is sort of helpful, but I'm still unable to get it working (I think the issue is that I don't fully understand the GlassFish keystore, so I am modifying it incorrectly and the server throws security exceptions on startup). Does anyone have any experience doing so, and can you point me to a decent resource? Thanks for any help.

IIS is overriding my response content, if i manually set the Response.StatusCode

- by Pure.Krome

Hi Folks, Problem when i manually set the HTTP Status of my Response stream to .. say 404 or 503, IIS renders up the stock IIS content/view, instead of my custom view. When I do this with the Web Development Server (aka. Casinni), it works correctly (ie. my content is displayed and the response.statuscode == my entered data. Is there anyway I can override this behaviour? How To Replicate Make a default ASP.NET MVC1 web app. Add the following route public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{*catchall}", new { controller = "Home", action = "Index" } ); } Now replace the the HomeController's Index method with... [HandleError] public class HomeController : Controller { public ActionResult Index() { Response.StatusCode = 404; return View(); } } :( Please help!
