• Snow Leopard - Dock icons randomly disappear

  - by lostInTransit

  Snow Leopard works great! My mac's really fast after this. But sometimes the dock icons just disappear! I see the blue dot beneath when I click the empty space. So I know the item's there. But there are no icons! This happened for Safari and Downloads. Some people responded on the Apple forums that I should try and remove the dock's plist file. But this just restores the dock to its original settings! I don't want to lose my settings. Anyone else facing this issue with SL? Or is it a problem only I am facing? Thanks

• Solving &ldquo;XmlSchemaException: The global element '&lt;elementName&gt;' has already been declare

  - by ChrisD

  I recently encountered this error when I attempted to consume a new hosted WCF service.  The service used the Request/Response model and had been properly decorated.  The response and request objects were marked as DataContracts and had a specified namespace.   My WCF service interface was marked as a ServiceContract and shared the namespace attribute value.   Everything should have been fine, right? [ServiceContract(Namespace = "http://schemas.myclient.com/09/12")] public interface IProductActivationService { [OperationContract] ActivateSoftwareResponse ActivateSoftware(ActivateSoftwareRequest request); } well, not exactly.  Apparently the WSDL generator was having an issue: System.Xml.Schema.XmlSchemaException: The global element 'http://schemas.myclient.com/09/12:ActivateSoftwareResponse' has already been declared. After digging I’ve found the problem; the WSDL generator has some reserved suffixes for its entities, including Response, Request, Solicit (see http://msdn.microsoft.com/en-us/library/ms731045.aspx).  The error message is actually the result of a naming conflict.  The WSDL generator uses the namespace of the service to build its reserved types.  The service contract and data contract share a namespace, which coupled with the response/request name suffixes I was using in my class names, resulted in the SchemaException. The Fix: Two options: Rename my data contract entities to use a non-reserved keyword suffix (i.e.  change ActivateSoftwareResponse to ActivateSoftwareResp). or; Change the namespace of the data contracts to differ from the service contract namespace. I chose option 2 and changed all my data contracts to use a “http://schemas.myclient.com/09/12/data” namespace value. This avoided a name collision and I was able to produce my WSDL and consume my service.

• Problem opening password encrypted .docx file on Word 2003

  - by molecule

  Hi all, I am having a problem opening a .docx file on my Word 2003. I have installed the Compatibility pack for 2007 but when i try to open this particular file, I receive the error "Word experienced an error trying to open the file. Try these suggestions. 1. Check the file permissions for the document, 2. Make sure there is sufficient free memory and disk space, 3. Open the file with the Text Recovery converter. I do not think it is any of the errors as I am able to open it on a different PC with Word 2003 as well. I also do not have any issues opening any non-password encrypted .docx files. Has anyone experienced the same issue? Most posts on the internet relate to "open and repair" but as mentioned, I am able to open this file on another PC without any problems. Any advice is greatly appreciated. Thanks, George

• How much does the geographical location of DNS servers matter?

  - by GreatFire

  We have started to run our own DNS servers located in Asia since that's where our main audience is. However, it seems that some users in the US are having difficulties accessing our website sometimes. I've noticed myself that DNS lookups of our domain from the US are relatively slow (500 msec+). Maybe the problems some users are having are due to other DNS configuration errors, but in general, how much of an issue is the geographical location of DNS servers? Should we have an additional server in the US?

• Limit number of simultaneous connections squid makes to a single server

  - by Ben Voigt

  Note: I am asking about outbound concurrent connection limits, not inbound, which is sufficiently covered on existing questions Modern browsers typically open a large number of simultaneous connections, to take advantage of the fact that TCP fairly shares bandwidth between connections. Of course, this doesn't result in fair sharing between users, so some servers have started penalizing hosts which open too many connections. This limit can be configured client-side (e.g. IE MaxConnectionsPerServer, Firefox network.http.max-connections-per-server), but the method differs for each browser and version, and many users aren't competent to adjust it themselves. So we turn to a squid transparent HTTP proxy for central management of HTTP download. How can the number of simultaneous connections from squid to a remote webserver be limited, so the webserver doesn't perceive it as abuse of concurrent connections? Ideally the limit would be per source address. Squid should accept virtually unlimited concurrent requests from the client browser, and issue them sequentially to the remote server, only N at a time, delaying (but not dropping) the others.

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• Unable to set NTFS permissions for ApplicationPoolIdentity on Windows 2008 SP2

  - by Kev

  On Windows 2008 R2 I am able to set NTFS permissions for an application pool's synthesised ApplicationPoolIdentity account thus: ICACLS d:\websites\site1\www /grant "IIS AppPool\site1":(CI)(OI)(M) The website's application pool is named site1 and is configured to run as ApplicationPoolIdentity. The site's authentication is also configured to authenticate as ApplicationPoolIdentity. I've done this a thousand times on Windows 2008 Standard Edition R2 with never a hitch. However if I try to do the same in Windows 2008 Standard Edition SP2 I get the error: IIS AppPool\site1: No mapping between account names and security IDs was done. Successfully processed 0 files; Failed processing 1 files I also notice that this fails if I try to set permissions for the application pool identity via the security GUI as well. I've seen this before and a reboot has cleared this issue but I'd like to know why this happens periodically. Googling around suggests other folks have hit this problem but there's never a satisfactory explanation. Why would this be?

• How can I VPN into a domain and act as if it is local?

  - by Duall

  I've looked and looked and the internet seems to have finally failed me, there's no information on my specific issue. I have two locations, and one server (sbs 2008); I need them to act like one physical LAN. I know it's possible, I just know how to set it up, or anything about VPNs, etc. So, just to clarify a bit more: 1 Small Business Server 2008 ~30 Computers with varying systems from Windows XP to 7 2 Physical Locations I use redirected folders, but since that would consume a lot of bandwith over VPN, I have a machine over there that can be the workhorse for storage. Users need to access e-mail and shared databases from this server (or possibly some form of DFS with aforementioned workhorse) from the other building. Is there a nice tutorial (or I nice person that wants to write it) online that can explain how to set up computers from an external network to act like they were in the LAN?

• Breaking up classes and methods into smaller units

  - by micahhoover

  During code reviews a couple devs have recommended I break up my methods into smaller methods. Their justification was (1) increased readability and (2) the back trace that comes back from production showing the method name is more specific to the line of code that failed. There may have also been some colorful words about functional programming. Additionally I think I may have failed an interview a while back because I didn't give an acceptable answer about when to break things up. My inclination is that when I see a bunch of methods in a class or across a bunch of files, it isn't clear to me how they flow together, and how many times each one gets called. I don't really have a good feel for the linearity of it as quickly just by eye-balling it. The other thing is a lot of people seem to place a premium of organization over content (e.g. 'Look at how organized my sock drawer is!' Me: 'Overall, I think I can get to my socks faster if you count the time it took to organize them'). Our business requirements are not very stable. I'm afraid that if the classes/methods are very granular it will take longer to refactor to requirement changes. I'm not sure how much of a factor this should be. Anyway, computer science is part art / part science, but I'm not sure how much this applies to this issue.

• To PHP or Not to PHP? [closed]

  - by Vad

  Should I learn PHP in depth for my smaller projects or not? My main knowledge is Java/JavaScript for the web. My old small projects were written in classic ASP. However, ASP had its days. Now I am looking into going deeper with another scripting language which I can use for small website projects. Though I know PHP on a basic level I never liked PHP. But I have to admit it is so widely used that I better start liking it. And all hosting services offer mostly PHP solutions. However, there is quite a number of issues with PHP when I google for it. Developers seem to not like it a lot. I wish I would use server-side JavaScript for all my needs, but hosting is an issue plus many small businesses already want to improve their existing PHP sites. And lastly, say I want to create a web app for distribution. PHP sounds like the best bet. Or am I wrong?

• Offset Forward vector of object based on Rotation

  - by Taylor

  I'm using the Bullet 3D physics engine in a iOS application running openGL ES 1.1 Currently I'm accepting info from the gyroscope to allow the user to "look around" a 3d world that follows a bouncing ball (note: it only takes in the yaw to look around 360 degrees). Im also accepting information from the accelerometer based on the tilt to push the ball. As of right now, to move forward, the user tilts the devise forward (using the accelerometer); to move to the right, the user tilts the devise to the right and so on. The forward vector is currently along it's local Z-axis. The problem is that I want to change the ball bounce based on where the user has changed the view. If I change the view, the ball bounces in the fixed direction. I want to change the forward facing direction so that when a user changes the view (say to the look at the right of the world, the user rotates the device), tilting the devise forward will result in a forward force in that direction. Basically, I want the forward vector to take the rotation into consideration. Sorry if I didn't explain the issue well enough, its kind of confusing to write down.

• Commit charge peak higher than system limit

  - by Grubsnik

  We are seeing some very strange behaviour on our servers and google didn't turn up anything usefull, so I'm tossing it out here. A standard server is configured with 4GB Ram, 2 4GB pagefiles and running windows server 2003. The servers are running 50-120 vb6/.net applications which normally consume no more than 100mb of memory, but will occasionally run up to 300 mb. The issue with a single process spending way too much memory is being traced down somewhere else, but the thing that is baffling us is that the reported peak charge is vastly higher than what we have available. As the image above shows, we are getting reported peaks that are way higher than what the system is actually capable of delivering. This number has been seen as high as 29GB, which makes no sense at all for a system with a limit of 12GB. Does anyone have an idea what is going on?

• Unknown/unsupported storage engine: InnoDB | Mysql Ubuntu

  I recently upgraded from the previous LTS Ubuntu to Precise and now mysql refuses to start. It complains of the following when I attempt to start it: ?$ sudo service mysql restart stop: Unknown instance: start: Job failed to start And this shows in "/var/log/mysql/error.log": 120415 23:01:09 [Note] Plugin 'InnoDB' is disabled. 120415 23:01:09 [Note] Plugin 'FEDERATED' is disabled. 120415 23:01:09 [ERROR] Unknown/unsupported storage engine: InnoDB 120415 23:01:09 [ERROR] Aborting 120415 23:01:09 [Note] /usr/sbin/mysqld: Shutdown complete I've checked permissions on all the mysql directories to make sure it had ownership and I also renamed the previou ib_logs so that it could remake them. I'm just getting no where with this issue right now, after looking at google results for 2 hours.

• Apache Tomcat 6.0.29 startup causing Win XP SP3 reboot

  - by Liam

  Some of our Windows XP Developer machines die (black screen - no ping) when starting up Tomcat from a console. This only happens if the Tomcat debug console window is displayed (not minimised). When minimised, the startup / run is successful. I've checked for Tomcat logs and the crash sessions produce empty (zero bytes) tomcat log files. No system logs exist and no crash dump is created even though this is enabled in the Windows settings. The machine is dual screen and another machine with the same image has the same issue. The only clue is just before the crash, one of the monitors the system reports "Cannot display video mode 1280x1024" (approximate error, didn't write it down). Is there a way I can get Windows to produce log files of this crash session? Beyond running Tomcat as a service / minimised window, how can I fix (or even investigate)?

• How to make a text search template?

  - by Flipper

  I am not really sure what to call this, but I am looking for a way to have a "template" for my code to go by when searching for text. I am working on a project where a summary for a piece of text is supplied to the user. I want to allow the user to select a piece of text on the page so that the next time they come across a similar page I can find the text. For instance, lets say somebody goes to foxnews.com and selects the article like in the image below. Then whenever they go to any other foxnews.com article I would be able to identify the text for the article and summarize it for them. But an issue I see with this is for a site like Stack Exchange where you have multiple comments to be selected (like below) which means that I would have to be able to recursively search for all separate pieces of text. Requirements Be able to keep pieces of text separate from each other. Possible Issues DIV's may not contain ids, classes, or names. A piece of text may span across multiple DIVs How to recognize where an old piece of text ends and a new begins. How to store this information for later searching?

• Saving Photoshop workspace doesn't remember docked panel state

  - by johnh

  A friend of mine has recently setup his computer with a fresh install of Windows 7 and Photoshop CS5. He's having a strange issue with saved workspaces not remembering the state of docked panels. As an example, he's docked several panels on the right of the screen. The Layers panel is docked but is open, showing all layers in the document. If he saves this as a workspace, closes and reopens Photoshop and loads the workspace, the Layers panel is docked but is closed. It's not the only panel this is happening with. It's not a big problem but he's having to open 4 panels and drag them to the appropriate height each time he starts Photoshop. Does anyone know of a possible fix for this? Any insight would be great.

• Intermittent USB 3.0 access - How do I troubleshoot?

  - by Billy ONeal

  I've got a WD Passport hard disk with "superspeed" USB 3.0 support. When I use my USB 3.0 flash drive (this is a Lenovo X220 laptop), USB 3.0 consistently works. But when I use the passport drive, almost without fail the connection drops to USB 2.0. Touching the cable seems to immediately trigger the problem, but it seems to happen on its own though. I've got another cable on order right now... but is it likely the cable's the issue here? Is there anything else I can check?

• Inexplicable low ranking [closed]

  - by Mick

  I have created two similar websites relating to monetary systems. So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. The successful one is fullreservebanking.com. If you type in "full reserve banking" into Google, my site appears 2nd in the list behind Wikipedia. The unsuccessful one is fractionalreserves.com. If you type in "fractional reserve banking" into Google, it's nowhere to be seen. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for fullreservebanking, but fractionalreserves is just an "add-on" which sits on a subdirectory of fullreservebanking. I wonder if Google somehow detects this and treats it as a less significant website?

• Finding Buried Controls

  - by Bunch

  This post is pretty specific to an issue I had but still has some ideas that could be applied in other scenarios. The problem I had was updating a few buttons so their Text values could be set in the code behind which had a method to grab the proper value from an external source. This was so that if the application needed to be installed by a customer using a language other than English or needed a different notation for the button's Text they could simply update the database. Most of the time this was no big deal. However I had one instance where the button was part of a control, the button had no set ID and that control was only found in a dll. So there was no markup to edit for the Button. Also updating the dll was not an option so I had to make the best of what I had to work with. In the cs file for the aspx file with the control on it I added the Page_LoadComplete. The problem button was within a GridView so I added a foreach to go through each GridViewRow and find the button I needed. Since I did not have an ID to work with besides a random ctl00$main$DllControl$gvStuff$ctl03$ctl05 using the GridView's FindControl was out. I ended up looping through each GridViewRow, then if a RowState equaled Edit loop through the Cells, each control in the Cell and check each control to see if it held a Panel that contained the button. If the control was a Panel I could then loop through the controls in the Panel, find the Button that had text of "Update" (that was the hard coded part) and change it using the method to return the proper value from the database. if (rowState.Contains("Edit")){  foreach (DataControlFieldCell rowCell in gvr.Cells)  {   foreach (Control ctrl in rowCell.Controls)   {    if (ctrl.GetType() == typeof(Panel))     {     foreach (Control childCtrl in ctrl.Controls)     {      if (childCtrl.GetType() == typeof(Button))      {       Button update = (Button)childCtrl;       if (update.Text == "Update")       {        update.Text = method to return the external value for the button's text;       }      }     }    }   }  }} Tags: ASP.Net, CSharp

• Code execution time out occationally

  - by Athul k Surendran

  I am working on an e-commerce website. There is a case where I need to fetch the whole data in database through third-party API and send it to an indexing engine. This third-party API has many functions like getproducts, getproductprice, etc., and each of that functions will return the data in XML format. From there I will take charge, I will use various API calls and will handle the XML data with XSLT. And will write to a CSV file. This file will be uploaded to an Indexing engine. Right now I have details of 8000 products to feed the engine, and almost all time the this process takes about 15 min to complete, and sometimes fails. I can't find a better solution for this. I am thinking about handling the XML data in C# itself and get rid of XSLT. As I think, XSLT is far slower than C#. Is it a good Idea? Or what else I can do to solve this issue?

• How do you price your work?

  - by Dr.Kameleon

  Well, let me explain : This has really been an issue for me, for such a long time. And what is worse - since coding is something I simply ADORE (I would definitely do it, even if there was no payment involved whatsoever..) - is that I always end up feeling somewhat awkward... Anyway... So, here's the deal : You start working on a project, you may have something in your mind, and even if you're lucky enough and the client needs no "cost estimates" beforehand, sooner or later you'll face the ultimate dilemma of pricing your own work. So, how do YOU do it? By estimating the time you put into it? (obviously, this is not exact, 'coz perhaps a more capable coder will need much less time for the very same thing than a not-so-competent coder + even the very same coder may not "perform" equally at all times) By the Lines of code you've written? (obviously, this is not a measure either : a 10-line script that does exactly the same with a 1000-line script is, at least for me, "better") By taking into account the level of complexity of the project and, perhaps, how specialised the subject is? By taking into account other factors? (e.g. the value of the project for your customer)

• Slow website load with CNAME, fast when using IP

  - by Nate Strandberg

  I setup two DNS servers on my network: ns1.byte-werx.com && ns2.byte-werx.com I can ping the DNS servers and get a fairly good response time, when I dig them I also get a fairly reasonable response, but any website I filter through them is painfully slow (an upwards of 20+ seconds) -- verifiable by performing a tracert or attempting to access the URL in a browser. The DNS servers are running CentOS 6.3 and BIND9 with 500MB of memory (I figure that should be more than enough?). I have a reverse look-up zone (1.168.192) along with two website zones (www.byte-werx.com and www.stayhomedental.com) If I access the websites using their IP the page loads nearly instantly so I do not believe the issue is with the hosting server, but that is running Ubuntu Server 12.04 and Apache2 with 12GB memory. Any thoughts? I do not have the named.conf file in front of me but I can edit this post to include it if you feel it would be useful. Thanks for any advice!

• Cisco Aironet 1200 Series AP Configuration

  - by nonterrorist

  I am attempting to configure a new CISCO Aironet 1200 Series Access Point to have a fixed IP. I have been searching online and I have come to the conclusion that the default IP address of this device is 10.0.0.1. These are the steps I have taken: My machine is plugged directly into the Ethernet port (not the Console port) of the AP. My Ethernet adapter is set to 10.0.0.2. I have reset the AP by holding the Mode button while powering up the device. The issue remains that I can not access 10.0.0.1 through the web, nor can I ping that address.
