• XML DB Content Connector unable to accept binary content due to Invalid argument(s) in call oracle.sql.BLOB.setBinaryStream(0L)

  - by sthieme

  Dear Readers, I am working on implementing a custom Document Management System using the Oracle XML DB Content Connector. See the following documentation link for details Oracle XML DB Developer's Guide 11g Release 2 (11.2)Chapter 31 Using Oracle XML DB Content Connectorhttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm especially the following example gave me some trouble to run it successfully Sample Code to Upload Filehttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm#ADXDB5627 I had already succeeded to set some of the properties successfully, i.e. jcr:encoding, jcr:mimeType, ojcr:displayName and ojcr:language. However setting the jcr:data property as described in the example failed consistently, both with the documented input FileStream or with a fixed string. contentNode.setProperty("jcr:data", "mystringvalue"); After some research I found the following Support Note which describes the cause for the issue in the JDBC driver version 11.2.0.1. Error "ORA-17068: Invalid argument(s) in call" Using Method setBinaryStream(0L) in JDBC 11.2.0.1 (Doc ID 1234235.1)https://support.oracle.com/epmos/faces/DocContentDisplay?id=1234235.1It can easily be solved by upgrading to JDBC 11.2.0.2 or worked around using the following property setting: java -Doracle.jdbc.LobStreamPosStandardCompliant=false ...

• Prefilling an SMS on Mobile Devices with the sms: Uri Scheme

  - by Rick Strahl

  Popping up the native SMS app from a mobile HTML Web page is a nice feature that allows you to pre-fill info into a text for sending by a user of your mobile site. The syntax is a bit tricky due to some device inconsistencies (and quite a bit of wrong/incomplete info on the Web), but it's definitely something that's fairly easy to do.In one of my Mobile HTML Web apps I need to share a current location via SMS. While browsing around a page I want to select a geo location, then share it by texting it to somebody. Basically I want to pre-fill an SMS message with some text, but no name or number, which instead will be filled in by the user.What worksThe syntax that seems to work fairly consistently except for iOS is this:sms:phonenumber?body=messageFor iOS instead of the ? use a ';' (because Apple is always right, standards be damned, right?):sms:phonenumber;body=messageand that works to pop up a new SMS message on the mobile device. I've only marginally tested this with a few devices: an iPhone running iOS 6, an iPad running iOS 7, Windows Phone 8 and a Nexus S in the Android Emulator. All four devices managed to pop up the SMS with the data prefilled.You can use this in a link:<a href="sms:1-111-1111;body=I made it!">Send location via SMS</a>or you can set it on the window.location in JavaScript:window.location ="sms:1-111-1111;body=" + encodeURIComponent("I made it!");to make the window pop up directly from code. Notice that the content should be URL encoded - HTML links automatically encode, but when you assign the URL directly in code the text value should be encoded.Body onlyI suspect in most applications you won't know who to text, so you only want to fill the text body, not the number. That works as you'd expect by just leaving out the number - here's what the URLs look like in that case:sms:?body=messageFor iOS same thing except with the ;sms:;body=messageHere's an example of the code I use to set up the SMS:var ua = navigator.userAgent.toLowerCase(); var url; if (ua.indexOf("iphone") > -1 || ua.indexOf("ipad") > -1) url = "sms:;body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); else url = "sms:?body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); location.href = url;and that also works for all the devices mentioned above.It's pretty cool that URL schemes exist to access device functionality and the SMS one will come in pretty handy for a number of things. Now if only all of the URI schemes were a bit more consistent (damn you Apple!) across devices...© Rick Strahl, West Wind Technologies, 2005-2013Posted in IOS  JavaScript  HTML5   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Lessons Building KeyRef (a .NET developer learning Rails)

  - by Liam McLennan

  Just because I like to build things, and I like to learn, I have been working on a keyboard shortcut reference site. I am using this as an opportunity to improve my ruby and rails skills. The first few days were frustrating. Perhaps the learning curve of all the fun new toys was a bit excessive. Finally tonight things have really started to come together. I still don’t understand the rails built-in testing support but I will get there. Interesting Things I Learned Tonight RubyMine IDE Tonight I switched to RubyMine instead of my usual Notepad++. I suspect RubyMine is a powerful tool if you know how to use it – but I don’t. At the moment it gives me errors about some gems not being activated. This is another one of those things that I will get to. I have also noticed that the editor functions significantly differently to the editors I am used to. For example, in visual studio and notepad++ if you place the cursor at the start of a line and press left arrow the cursor is sent to the end of the previous line. In RubyMine nothing happens. Haml Haml is my favourite view engine. For my .NET work I have been using its non-union Mexican CLR equivalent – nHaml. Multiple CSS Classes To define a div with more than one css class haml lets you chain them together with a ‘.’, such as: .span-6.search_result contents of the div go here Indent Consistency I also learnt tonight that both haml and nhaml complain if you are not consistent about indenting. As a consequence of the move from notepad++ to RubyMine my haml views ended up with some tab indenting and some space indenting. For the view to render all of the indents within a view must be consistent. Sorting Arrays I guessed that ruby would be able to sort an array alphabetically by a property of the elements so my first attempt was: Application.all.sort {|app| app.name} which does not work. You have to supply a comparer (much like .NET). The correct sort is: Application.all.sort {|a,b| a.name.downcase <=> b.name.downcase} MongoMapper Find by Id Since document databases are just fancy key-value stores it is essential to be able to easily search for a document by its id. This functionality is so intrinsic that it seems that the MongoMapper author did not bother to document it. To search by id simply pass the id to the find method: Application.find(‘4c19e8facfbfb01794000002’) Rails And CoffeeScript I am a big fan of CoffeeScript so integrating it into this application is high on my priorities. My first thought was to copy Dr Nic’s strategy. Unfortunately, I did not get past step 1. Install Node.js. I am doing my development on Windows and node is unix only. I looked around for a solution but eventually had to concede defeat… for now. Quicksearch The front page of the application I am building displays a list of applications. When the user types in the search box I want to reduce the list of applications to match their search. A quick googlebing turned up quicksearch, a jquery plugin. You simply tell quicksearch where to get its input (the search textbox) and the list of items to filter (the divs containing the names of applications) and it just works. Here is the code: $('#app_search').quicksearch('.search_result'); Summary I have had a productive evening. The app now displays a list of applications, allows them to be sorted and links through to an application page when an application is selected. Next on the list is to display the set of keyboard shortcuts for an application.

• Ajax Autocomplete Extender

  - by Jason Ulloa

  El objetivo de este post es preparar un ejemplo sobre un tema que es planteado muy frecuentemente en los Foros de MSDN, como realizar un Autocomplete contra una base de datos. Qué requerimos? Antes de poder realizar un Autocomplete debemos tener en cuenta los elementos principales que requerimos para poder hacerlo funcionar, descritos de la siguiente manera: 1. Textbox: Nuestro grandioso amigo Textbox, que será donde el usuario ingresará los datos a buscar. 2. Un Webservice: que contendrá el método que se conectara a la base de datos y devolverá una lista con la información encontrada. 3. Ajax Autocomplete Extender: este es por decirlo así, el elemento más importante. Nos servirá como medio de enlace entre el webservice que expone el método y el textbox recuperando y mostrando los datos en forma de lista desplegable. La implementación Si bien parecierá complicado, crear un autocomplete extender es bastante sencillo. Empezaremos creando un nuevo sitio asp.net, en este sitio agregaremos un textbox y dos controles muy importantes de Ajax el ToolkitScriptManager para controlar el rende rizado de los script de ajax y el AutocompleteExtender que, como mencione anteriormente, será el medio de enlace. Antes de mostrar como quedará el código de lo anterior, explicaré algunas propiedades del AutocompleteExtender para que se entienda de mejor manera: 1. El ServicePath: contiene la ruta relativa al webservice que utilizaremos. 2. MinimumPrefixLength: se refiere al número de caracteres que deben ser digitados antes de iniciar la búsqueda. 3. ServiceMethod: el nombre del metodo de nuestro webservice que se encargará de devolver los datos. 4. EnableCaching: para mantener en cache los datos consultados, obteniendo mayor velocidad. 5. TargetControlID: una de las propiedades más importantes, acá se coloca el nombre del textbox al cual se unirá el Autocomplete 6. CompletionInterval: tiempo que debe transcurrir antes de iniciar con el trabajo de los datos. Una vez, explicadas las propiedades básicas, veamos como queda implementada la primer parte de nuestro autocomplete: <form id="form1" runat="server"> <div> <asp:ToolkitScriptManager ID="manager" runat="server" /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" ServicePath="WebService.asmx" MinimumPrefixLength="1" ServiceMethod="PersonasInfo " EnableCaching="true" TargetControlID="TextBox1" UseContextKey="True" CompletionSetCount="10" CompletionInterval="0"> </asp:AutoCompleteExtender> </div> </form>   Ahora que nuestro código html está completo, es hora de trabajar directamente con nuestro webservice, este deberá contener un método que devuelva una lista o arreglo de datos, los cuales por supuesto, serán traídos desde la base de datos. Antes de implementar este método, debemos asegurarnos de que nuestra clase del webservice tiene habilitados los espacios para ser utilizada [System.Web.Script.Services.ScriptService()] [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class WebService : System.Web.Services.WebService {}   Ahora si, nuestro metodo principal [WebMethod()] [System.Web.Script.Services.ScriptMethod()] public string[] PersonasInfo(string prefixText, int count) { string connstring = ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString;   using (SqlConnection conn = new SqlConnection(connstring)) { SqlCommand comando = new SqlCommand("select nombre from personas where nombre LIKE '%' + @param + '%' ", conn); comando.Parameters.AddWithValue("@param", prefixText); SqlDataReader dr = default(SqlDataReader); comando.Connection.Open(); dr = comando.ExecuteReader(); List<string> items = new List<string>();   while (dr.Read()) { items.Add(dr["nombre"].ToString()); } comando.Connection.Close(); return items.ToArray(); } }   Del método anterior no explicaré en profundidad, pues es bastante sencillo. Una consulta a la base de datos utilizando un datareader y devolviendo los datos en una lista como arreglo. Lo más importante serían las 2 primeras líneas [WebMethod()] y el [ScriptMethod()] las cuales habilitan nuestro método para poder ser accedido y utilizado. Por último, el código de ejemplo en C# (VB Autcomplete):

• SQL SERVER – Asynchronous Update and Timestamp – Check if Row Values are Changed Since Last Retrieve

  - by pinaldave

  Here is the question received just this morning. “Pinal, Our application is much different than other application you might have come across. In simple words, I would like to call it Asynchronous Updated Application. We need your quick opinion about one of the situation which we are facing. From business side: We have bidding system (similar to eBay but not exactly) and where multiple parties bid on one item, during the last few minutes of bidding many parties try to bid at the same time with the same price. When they hit submit, we would like to check if the original data which they retrieved is changed or not. If the original data which they have retrieved is the same, we will accept their new proposed price. If original data are changed, they will have to resubmit the data with new price. From technical side: We have a row which we retrieve in our application. Multiple users are retrieving the same row. Some of the users will update the value of the row and submit. However, only the very first user should be allowed to update the row and remaining all the users will have to re-fetch the row and updated it once again. We do not want to lock any record as that will create other problems. Do you have any solution for this kind of situation?” Fantastic Question. I believe there is good chance that we can use timestamp datatype in this kind of application. Before we continue let us see following simple example. USE tempdb GO CREATE TABLE SampleTable (ID INT, Col1 VARCHAR(100), TimeStampCol TIMESTAMP) GO INSERT INTO SampleTable (ID, Col1) VALUES (1, 'FirstVal') GO SELECT ID, Col1, TimeStampCol FROM SampleTable st GO UPDATE SampleTable SET Col1 = 'NextValue' GO SELECT ID, Col1, TimeStampCol FROM SampleTable st GO DROP TABLE SampleTable GO Now let us see the resultset. Here is the simple explanation of the scenario. We created a table with simple column with TIMESTAMP datatype. When we inserted a very first value the timestamp was generated. When we updated any value in that row, the timestamp was updated with the new value. Every single time when we update any value in the row, it will generate new timestamp value. Now let us apply this in an original question’s scenario. In that case multiple users are retrieving the same row. Everybody will have the same now same TimeStamp with them. Before any user update any value they should once again retrieve the timestamp from the table and compare with the timestamp they have with them. If both of the timestamp have the same value – the original row has not been updated and we can safely update the row with the new value. After initial update, now the row will contain a new timestamp. Any subsequent update to the same row should also go to the same process of checking the value of the timestamp they have in their memory. In this case, the timestamp from memory will be different from the timestamp in the row. This indicates that row in the table has changed and new updates should not be allowed. I believe timestamp can be very very useful in this kind of scenario. Is there any better alternative? Please leave a comment with the suggestion and I will post on the blog with due credit.

• Rewriting Apache URLs to use only paths and set response headers

  - by jabley

  I have apache httpd in front of an application running in Tomcat. The application exposes URLs of the form: /path/to/images?id={an-image-id} The entities returned by such URLs are images (even though URIs are opaque, I find human-friendly ones are easier to work with!). The application does not set caching directives on the image response, so I've added that via Apache. # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> Note that I can't use ExpiresByType since not all images served by the app have versioned URIs. I know that ones served by the /path/to/images resource handler are versioned URIs though, which don't perform any sort of content negotiation, and thus are ripe for Far Future Expires management. This is working well for us. Now a requirement has come up to put something else in front of the app (in this case, Amazon CloudFront) to further distribute and cache some of the content. Amazon CloudFront will not pass query string parameters through to my origin server. I thought I would be able to work around this, by changing my apache config appropriately: # Rewrite to map new Amazon CloudFront friendly URIs to the application resources RewriteRule ^/new/path/to/images/([0-9]+) /path/to/images?id=$1 [PT] # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> This works fine in terms of serving the content, but there are no longer caching directives with the response. I've tried playing around with [PT], [P] for the RewriteRule, and adding a new LocationMatch directive: # Rewrite to map new Amazon CloudFront friendly URIs to the application resources # /new/path/to/images/12345 -> /path/to/images?id=12345 RewriteRule ^/new/path/to/images/([0-9]+) /path/to/images?id=$1 [PT] # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> <LocationMatch "^/new/path/to/images/"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> Unfortunately, I'm still unable to get the Cache-Control header added to the response with the new URL format. Please point out what I'm missing to get /new/path/to/images/12345 returning a 200 response with a Cache-Control: max-age=8640000 header. Pointers as to how to debug apache like this would be appreciated as well!

• Internet Explorer and margins

  - by Hailwood

  Hi there. I have some pretty simple html which is meant to make a layout as below. To push the tabs down from the userbar I am using margin-top: 35px; However in internet explorer the tabs are completly misaligned(the top of the tabs is where the bottom should be). So I need to use margin-top: -50px; for internet explorer. Why is this and how can I fix it without using a ie specific stylesheet <div id="pageHead"> <div id="userBar"> <span class="bold">Hi Matthew Hailwood | <a href="#">Logout</a> </div> <a href="http://localhost/buzz/" id="pageLogo"></a> <div id="pageTabs" class="clearfix"> <ul> <li><a href="http://localhost/buzzil/templates">Templates</a></li> <li><a href="http://localhost/buzzil/messaging">Messaging</a></li> <li><a href="http://localhost/buzzil/contacts">Contacts</a></li> </ul> </div> </div> With the css being #pageHead { height: 100px; } #pageLogo { float: left; width: 149px; height: 77px; margin-top: 11px; background: transparent url('../images/logo.png') no-repeat; } #userBar { text-align: right; color: #fff; margin-top: 10px; } #userBar a:link, #userBar a:visited, #userBar a:active { font-weight: normal; color: #E0B343; text-decoration: none; } .clearfix:after { content: "."; display: block; clear: both; visibility: hidden; line-height: 0; height: 0; } .clearfix { display: inline-block; } html[xmlns] .clearfix { display: block; } * html .clearfix { height: 1%; } #pageTabs { float: right; margin-top: 35px; } #pageTabs ul { position: relative; width: 100%; list-style: none; margin: 0; padding: 0; border-left: 1px solid #000; } #pageTabs ul li { float: right; background: url(../images/tabsBg.png) no-repeat 0% 0%; border-left: 1px solid #000; margin-left: -1px; } #pageTabs ul li a:link, #pageTabs ul li a:visited, #pageTabs ul li a:active { color: #fff; background: url(../images/tabsBg.png) no-repeat 100% 0%; display: block; font-size: 14px; font-weight: bold; line-height: 42px; text-transform: uppercase; padding: 4px 32px; text-decoration: none; } #pageTabs ul li a:hover, #pageTabs ul li a:focus { text-decoration: underline; }

• Design pattern for logging changes in parent/child objects saved to database

  - by andrew

  I’ve got a 2 database tables in parent/child relationship as one-many. I’ve got three classes representing the data in these two tables: Parent Class { Public int ID {get; set;} .. other properties } Child Class { Public int ID {get;set;} Public int ParentID {get; set;} .. other properties } TogetherClass { Public Parent Parent; Public List<Child> ChildList; } Lastly I’ve got a client and server application – I’m in control of both ends so can make changes to both programs as I need to. Client makes a request for ParentID and receives a Together Class for the matching parent, and all of the child records. The client app may make changes to the children – add new children, remove or modify existing ones. Client app then sends the Together Class back to the server app. Server app needs to update the parent and child records in the database. In addition I would like to be able to log the changes – I’m doing this by having 2 separate tables one for Parent, one for child; each containing the same columns as the original plus date time modified, by whom and a list of the changes. I’m unsure as to the best approach to detect the changes in records – new records, records to be deleted, records with no fields changed, records with some fields changed. I figure I need to read the parent & children records and compare those to the ones in the Together Class. Strategy A: If Together class’s child record has an ID of say 0, that indicates a new record; insert. Any deleted child records are no longer in the Together Class; see if any of the comparison child records are not found in the Together class and delete if not found (Compare using ID). Check each child record for changes and if changed log. Strategy B: Make a new Updated TogetherClass UpdatedClass { Public Parent Parent {get; set} Public List<Child> ListNewChild {get;set;} Public List<Child> DeletedChild {get;set;} Public List<Child> ExistingChild {get;set;} // used for no changes and modified rows } And then process as per the list. The reason why I’m asking for ideas is that both of these solutions don’t seem optimal to me and I suspect this problem has been solved already – some kind of design pattern ? I am aware of one potential problem in this general approach – that where Client App A requests a record; App B requests same record; A then saves changes; B then saves changes which may overwrite changes A made. This is a separate locking issue which I’ll raise a separate question for if I’ve got trouble implementing. The actual implementation is c#, SQL Server and WCF between client and server - sharing a library containing the class implementations. Apologies if this is a duplicate post – I tried searching various terms without finding a match though.

• How do I configure WakeOnUSB properly?

  - by wishi

  How do I configure Wake-On-USB properly on a 10.04 or 10.10 Ubuntu (2.6.36 and higher if needed)? (Wake-on-USB is when the computer is asleep and for example a USB Keyboard event wakes up the machine!) The notebook is an Acer Aspire Timeline X 1830T. I don't know in which way the Linux Kernel supports the controllers. There are different ways to approach this, for example /proc/acpi/wakeup... or UDEV... or something with HAL? /proc/acpi/wakeup shows every device in S4, but I need S3. Device S-state Status Sysfs node P0P2 S4 *disabled PEGP S4 *disabled P0P1 S0 *disabled pci:0000:00:1e.0 EHC1 S4 *disabled pci:0000:00:1d.0 USB1 S4 *enabled USB2 S4 *disabled USB3 S4 *disabled USB4 S4 *disabled EHC2 S4 *disabled pci:0000:00:1a.0 USB5 S4 *disabled USB6 S4 *disabled USB7 S4 *disabled HDEF S0 *disabled pci:0000:00:1b.0 RP01 S5 *disabled pci:0000:00:1c.0 PXSX S5 *disabled pci:0000:01:00.0 RP02 S0 *disabled pci:0000:00:1c.1 PXSX S5 *disabled pci:0000:02:00.0 RP03 S0 *disabled PXSX S5 *disabled RP04 S0 *disabled PXSX S5 *disabled RP05 S0 *disabled PXSX S5 *disabled RP07 S0 *disabled PXSX S5 *disabled RP08 S0 *disabled PXSX S5 *disabled GLAN S0 *disabled PEG3 S4 *disabled PEG5 S4 *disabled PEG6 S4 *disabled SLPB S3 *enabled S4, which is Suspend-To-Disk afaik... doesn't seem to work either if I echo USB1 into the wakeup table. It just sets an S4 flag. can I get the USB ports in S3? I want to make the machine wakeup from Suspend-To-Ram (S3, ACPI standard) in case a key on my external keyboard is pressed. It only wakes up if a key on the internal Laptop keyboard is pressed... from Suspend To Ram. It seems if I plug in a USB mouse, that the USB port isn't even powered. I have no BIOS option to change this.

Any hints for good information here? I hope it's possible... I'm just looking for any solution. edit: this, waking up on USB, works on Windows! Thanks a lot, Marius

• PowerShell Script To Find Where SharePoint 2007 Features Are Activated

  - by Brian T. Jackett

  Recently I posted a script to find where SharePoint 2010 Features Are Activated.  I built the original version to use SharePoint 2010 PowerShell commandlets as that saved me a number of steps for filtering and gathering features at each level.  If there was ever demand for a 2007 version I could modify the script to handle that by using the object model instead of commandlets.  Just the other week a fellow SharePoint PFE Jason Gallicchio had a customer asking about a version for SharePoint 2007.  With a little bit of work I was able to convert the script to work against SharePoint 2007.   Solution    Below is the converted script that works against a SharePoint 2007 farm.  Note: There appears to be a bug with the 2007 version that does not give accurate results against a SharePoint 2010 farm.  I ran the 2007 version against a 2010 farm and got fewer results than my 2010 version of the script.  Discussing with some fellow PFEs I think the discrepancy may be due to sandboxed features, a new concept in SharePoint 2010.  I have not had enough time to test or confirm.  For the time being only use the 2007 version script against SharePoint 2007 farms and the 2010 version against SharePoint 2010 farms.    Note: This script is not optimized for medium to large farms.  In my testing it took 1-3 minutes to recurse through my demo environment.  This script is provided as-is with no warranty.  Run this in a smaller dev / test environment first. 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 function Get-SPFeatureActivated { # see full script for help info, removed for formatting [CmdletBinding()] param(     [Parameter(position = 1, valueFromPipeline=$true)]     [string]     $Identity )#end param     Begin     {         # load SharePoint assembly to access object model         [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")             # declare empty array to hold results.

• lvm disappeared after disc replacement on raid10

  - by user142295

  here my problem: I am running ubuntu 12.04 on a raid10 (4 disks), on top of which I installed an lvm with two volume groups (one for /, one for /home). The layout of the disks are as follows: Disk /dev/sda: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0003f3b6 Device Boot Start End Blocks Id System /dev/sda1 * 63 481949 240943+ 83 Linux /dev/sda2 481950 2910640634 1455079342+ fd Linux raid autodetect /dev/sda3 2910640635 2930272064 9815715 82 Linux swap / Solaris Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00069785 Device Boot Start End Blocks Id System /dev/sdb1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdb2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdc2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdd: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f14de Device Boot Start End Blocks Id System /dev/sdd1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdd2 2910158685 2930272064 10056690 82 Linux swap / Solaris The first disk (/dev/sda) contains the /boot partition on /dev/sda1. I use grub2 to boot the system off this partition. On top of this raid10 I installed two volume groups, one for /, one for /home. This system worked well, I even exchanged two disks during the last two years. It always worked. But not this time. For the first time, /dev/sda broke. I do not know if this is an issue – I know I would have struggled anyways to overcome the problem with /boot installed on that disk and grub2 installed on the mbr of /dev/sda. Anyways, I did what I always did: start knoppix fire up the raid sudo mdadm --examine -scan which returns ARRAY /dev/md127 UUID=0dbf4558:1a943464:132783e8:19cdff95 start it up sudo mdadm --assemble /dev/md127 fail the failing disk (smart event) sudo mdadm /dev/md127 --fail /dev/sda2 remove the failing disk sudo mdadm /dev/md127 --remove /dev/sda2 stop the raid sudo mdadm -S /dev/md127 take out the disk replace it with a new one create the same partitions as on the failling one add it to the raid sudo mdadm --assemble /dev/md127 sudo mdadm /dev/md127 --add /dev/sda2 wait 4 hours All looks fine: cat /proc/mdstat returns: Personalities : [raid10] md127 : active raid10 sda2[0] sdd1[3] sdc1[2] sdb1[1] 2910158464 blocks 64K chunks 2 near-copies [4/4] [UUUU] unused devices: <none> and sudo mdadm --detail /dev/md127 returns /dev/md127: Version : 0.90 Creation Time : Wed Jun 10 13:08:46 2009 Raid Level : raid10 Array Size : 2910158464 (2775.34 GiB 2980.00 GB) Used Dev Size : 1455079232 (1387.67 GiB 1490.00 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 127 Persistence : Superblock is persistent Update Time : Thu Mar 21 16:27:40 2013 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 64K UUID : 0dbf4558:1a943464:132783e8:19cdff95 (local to host Microknoppix) Events : 0.4824680 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 8 17 1 active sync /dev/sdb1 2 8 33 2 active sync /dev/sdc1 3 8 49 3 active sync /dev/sdd1 However, there is no trace of the volume groups. Rebooting into knoppix does not help Restarting the old system (I actually replugged and re-added the failing disk for that – the system begins to start, but then fails to see the / partition – no wonder if the volume group is gone) does not help. sudo vgscan, sudo vgdisplay, sudo lvs, sudo lvdisplay, sudo vgscan –mknodes all returned No volume groups found. I am completely at a loss. Can anyone tell me if and how I can recover my data? Thanks in advance!

• How to deal with overly aggressive "Link Take Down Demands"?

  - by Eoin

  I've been receiving a large number of emails recently requesting I clean from link spam from my forum. Initially the emails were very polite and professional, and I was happy to remove the links. Recently the email have gotten very abrasive, here is a particularly rude example: From: [email protected] To: [email protected] Hi, This is the second time we are reaching out to you regarding your link to our site hxxp://www.company-two.com from hxxp://www.my-forum.com/some-topic-id. We really do need to remove this link. We have to report to Google any link we were unable to remove, and I wouldn't want to have to include your site in the list. Could you please remove our link from this page and any other page on your site? Thank You, Name Changed Behind the superficial pleasantries I feel there is some very real maliciousness. Note the email address, DMCA Violations, I don't see how the DMCA is involved here, except as a word which tends to strike fear in many people. Also relating to the email address, it doesn't match the company being linked to at all. How am I to trust they are truely operating on behalf of company-two when they don't even use one of it's email addresses. My email is hidden by privacypost. While a service with legitimate uses, I feel it's highly unprofessional for communications between to companies. The claim "This is the second time..." Every email I've received has started like this, but a check of my spam filters has never revealed a 1st mail. Initially I gave them the benefit of the doubt, by now though it's clear this is a cheap ploy to start me off on the defensive. And finally worst of all- the threats of reporting me to Google if I don't do everything they ask. I sent a polite reply asking for more information. I have no idea if the email address was even valid but I never received any response. Much later I got this followup mail From: [email protected] To: [email protected] Hi, This is the final time we are reaching out to you regarding your link to our site hxxp://www.company-two.com from hxxp://www.my-forum.com/some-topic-id. We will soon be reporting to Google any link we were unable to remove, and currently your site will have to be on the list. Could you please remove our link from this page and any other page on your site? I appreciate your urgent attention to this matter. Thank You, Name Changed This time the from address was more personal, though still not obviously connected to the spammed company. Lets be honest, I don't for one second believe that the companies were the victim of a 3rd party spammer as they claim. The links in questions were generated well over a year ago, and I firmly believe the companies were directly responsible for the spam links in question, a type of spam that has plagued my forum. Now they have the audacity to demand I spend my time cleaning up their mess, using threats to ensure they get their way. Have recent changes in Googles algorithms meant all the cash they spent spamming the web has now turned into a liability? If so I can see why these companies are all of a sudden running scared. Frankly, cleaning up my forum is a good things, but the threats they are using sickens me. So my question here is specifically about the threats: Are they vaild, and would such reports to Google destroy my page rankings? Is there a way I can report this abusive behaviour to Google?

• Patterns for a tree of persistent data with multiple storage options?

  - by Robin Winslow

  I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

• Can anybody help me in designing my UITableView into MVC Pattern ?

  - by user2877880

  I have written a ViewController in which i get data from the internet and display it in a UItableview using a json parser which uses object for key to identify its objects. What i would like your help in is to convert it into MVC pattern to make it less clumsy instead of including everything in the same controller class.

• Failed to unmount partitions

  - by msknapp

  I'm trying to install ubuntu from a pen drive. I have windows 7 installed already and want to keep that installation. I have a 3TB drive that has one 2TB partition on it, so the last 1TB is completely unused, which is where I want to install ubuntu. I started ubuntu in "try ubuntu" mode and then opened gparted, and then deleted the unused partition for the last third of my drive, then tried to install ubuntu. During the install, it asked me if I wanted to unmount the drives I already have The installer has detected that the following disks have mounted partitions: /dev/sda, /dev/sdb Do you want the installer to try to unmount the partitions on these disks before continuing? If you leave them mounted, you will not be able to create, delete, or resize partitions on these disks, but you may be able to install to existing partitions there. No, Yes I said no because I don't want to lose my windows 7 installation, nor any of that data. I wonder, if I had said yes above, would I have lost all the data on those drives? Anyways, I hit no and continued. I chose to install ubuntu alongside windows 7, and hit continue. A few minutes passed when this popup appeared: Failed to unmount partitions The installer needs to commit changes to partition tables, but cannot do so because the partitions on the following mount points could not be unmounted: /media/ubuntu/Three\ Terabyte Drive Terabyte\ DriveDrive Please close any applications using these mount points. Would you like the installer to try to unmount these partitions again? Go Back, Continue Why is this not working? What am I supposed to do? ========== Update: I went ahead and said yes, it can unmount those partitions. It finished installing Ubuntu, but now when i start my machine it just takes me to the grub rescue prompt. Seems like it broke something.

• Instead of the specified Texture, black circles on a green background are getting rendered. Why?

  - by vinzBad

  I'm trying to render a Texture via OpenGL. But instead of the texture black circles on a green background are rendered. (They scale, depending what the rotation of the texture is) Example: The texture I'm trying to render is the following: This is the code I use to render the texture, it's located in my Sprite-class. public void Render() { Matrix4 matrix = Matrix4.CreateTranslation(-OriginX, -OriginY, 0) * Matrix4.CreateRotationZ(Rotation) * Matrix4.CreateTranslation(X, Y, 0); Vector2[] corners = { new Vector2(0,0), //top left new Vector2(Width ,0),//top right new Vector2(Width,Height),//bottom rigth new Vector2(0,Height)//bottom left }; //copy the corners to the uv coordinates Vector2[] uv = corners.ToArray<Vector2>(); //transform the coordinates for (int i = 0; i < 4; i++) corners[i] = new Vector2(Vector3.Transform(new Vector3(corners[i]), matrix)); //GL.Color3(TintColor); GL.BindTexture(TextureTarget.Texture2D, _ID); GL.Begin(BeginMode.Quads); { for (int i = 0; i < 4; i++) { GL.TexCoord2(uv[i]); GL.Vertex3(corners[i].X, corners[i].Y, _layerDepth); } } GL.End(); if (EnableDebugDraw) { GL.Color3(Color.Violet); GL.PointSize(3); GL.Begin(BeginMode.Points); { for (int i = 0; i < 4; i++) GL.Vertex2(corners[i]); } GL.End(); GL.Color3(Color.Green); GL.Begin(BeginMode.Points); GL.Vertex2(X, Y); GL.End(); } } This is how I setup OpenGL. public static void SetupGL() { GL.Enable(EnableCap.AlphaTest); GL.AlphaFunc(AlphaFunction.Greater, 0.1f); GL.Enable(EnableCap.Texture2D); GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest); } With this function I load the texture: public static uint LoadTexture(string path) { uint id; GL.GenTextures(1, out id); GL.BindTexture(TextureTarget.Texture2D, id); Bitmap bitmap = new Bitmap(path); BitmapData data = bitmap.LockBits(new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format32bppArgb); GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, data.Width, data.Height, 0, OpenTK.Graphics.OpenGL.PixelFormat.Bgra, PixelType.UnsignedByte, data.Scan0); bitmap.UnlockBits(data); GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, (int)TextureMinFilter.Linear); GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMagFilter, (int)TextureMagFilter.Linear); return id; } And here I call Sprite.Render() protected override void OnRenderFrame(FrameEventArgs e) { GL.ClearColor(Color.MidnightBlue); GL.Clear(ClearBufferMask.ColorBufferBit); _sprite.Render(); SwapBuffers(); base.OnRenderFrame(e); } As I stole this code from the Textures-Example from OpenTK, I don't understand why this doesn't work.

• Is this over-abstraction? (And is there a name for it?)

  - by mwhite

  I work on a large Django application that uses CouchDB as a database and couchdbkit for mapping CouchDB documents to objects in Python, similar to Django's default ORM. It has dozens of model classes and a hundred or two CouchDB views. The application allows users to register a "domain", which gives them a unique URL containing the domain name that gives them access to a project whose data has no overlap with the data of other domains. Each document that is part of a domain has its domain property set to that domain's name. As far as relationships between the documents go, all domains are effectively mutually exclusive subsets of the data, except for a few edge cases (some users can be members of more than one domain, and there are some administrative reports that include all domains, etc.). The code is full of explicit references to the domain name, and I'm wondering if it would be worth the added complexity to abstract this out. I'd also like to know if there's a name for the sort of bound property approach I'm taking here. Basically, I have something like this in mind: Before in models.py class User(Document): domain = StringProperty() class Group(Document): domain = StringProperty() name = StringProperty() user_ids = StringListProperty() # method that returns related document set def users(self): return [User.get(id) for id in self.user_ids] # method that queries a couch view optimized for a specific lookup @classmethod def by_name(cls, domain, name): # the view method is provided by couchdbkit and handles # wrapping json CouchDB results as Python objects, and # can take various parameters modifying behavior return cls.view('groups/by_name', key=[domain, name]) # method that creates a related document def get_new_user(self): user = User(domain=self.domain) user.save() self.user_ids.append(user._id) return user in views.py: from models import User, Group # there are tons of views like this, (request, domain, ...) def create_new_user_in_group(request, domain, group_name): group = Group.by_name(domain, group_name)[0] user = User(domain=domain) user.save() group.user_ids.append(user._id) group.save() in group/by_name/map.js: function (doc) { if (doc.doc_type == "Group") { emit([doc.domain, doc.name], null); } } After models.py class DomainDocument(Document): domain = StringProperty() @classmethod def domain_view(cls, *args, **kwargs): kwargs['key'] = [cls.domain.default] + kwargs['key'] return super(DomainDocument, cls).view(*args, **kwargs) @classmethod def get(cls, *args, **kwargs, validate_domain=True): ret = super(DomainDocument, cls).get(*args, **kwargs) if validate_domain and ret.domain != cls.domain.default: raise Exception() return ret def models(self): # a mapping of all models in the application. accessing one returns the equivalent of class BoundUser(User): domain = StringProperty(default=self.domain) class User(DomainDocument): pass class Group(DomainDocument): name = StringProperty() user_ids = StringListProperty() def users(self): return [self.models.User.get(id) for id in self.user_ids] @classmethod def by_name(cls, name): return cls.domain_view('groups/by_name', key=[name]) def get_new_user(self): user = self.models.User() user.save() views.py @domain_view # decorator that sets request.models to the same sort of object that is returned by DomainDocument.models and removes the domain argument from the URL router def create_new_user_in_group(request, group_name): group = request.models.Group.by_name(group_name) user = request.models.User() user.save() group.user_ids.append(user._id) group.save() (Might be better to leave the abstraction leaky here in order to avoid having to deal with a couchapp-style //! include of a wrapper for emit that prepends doc.domain to the key or some other similar solution.) function (doc) { if (doc.doc_type == "Group") { emit([doc.name], null); } } Pros and Cons So what are the pros and cons of this? Pros: DRYer prevents you from creating related documents but forgetting to set the domain. prevents you from accidentally writing a django view - couch view execution path that leads to a security breach doesn't prevent you from accessing underlying self.domain and normal Document.view() method potentially gets rid of the need for a lot of sanity checks verifying whether two documents whose domains we expect to be equal are. Cons: adds some complexity hides what's really happening requires no model modules to have classes with the same name, or you would need to add sub-attributes to self.models for modules. However, requiring project-wide unique class names for models should actually be fine because they correspond to the doc_type property couchdbkit uses to decide which class to instantiate them as, which should be unique. removes explicit dependency documentation (from group.models import Group)

• iphone - direct link to iPhone review form from inside iphone

  - by Mike

  I am trying to link directly to the review link of one of my Apps. I know that it is possible because Appirater did it in the past, but some change in iTunes turned the API down. Appirater uses this URL NSString *templateReviewURL = @"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=APP_ID&onlyLatestVersion=true&pageNumber=0&sortOrdering=1&type=Purple+Software"; where APP_ID is the ID of an application. running this from inside the APP gives me the message Cannot Connect to iTunes Store. This Page talks about another kind of link https://userpub.itunes.apple.com/WebObjects/MZUserPublishing.woa/wa/addUserReview?id=APP_ID&type=Purple+Software and also itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=APP_ID The first one works, but just from the desktop mac. The second gives me the same error as the first... Cannot Connect to iTunes Store. iTunes link maker is not helping too, because it has no tools for iPad links... Do you guys know how to link to an app's review form from inside an app? In case you don't know, what kind of package should I use to dig this? a package sniffer? thanks for any help.

• jQuery live draggable / live droppable?

  - by Henk

  Hi all, Basically there are two tables: Companies and visitors. Currently it's possible to drag visitors to companies. Works great. As soon as the drop function occurs, there are two $.post's. The first one saves the drag to the database. The second one updates the visitors, because the information constantly changes. The problem, however is that as soon as the second $.post finishes, Firebug keeps popping the following error: d(this).data("draggable") is null Which occurs in the jQuery UI file. On line 56. about 400 times or so. So basically I'm looking for a way to do live() with draggable and droppable. The .draggables are in #visitors (an ul). The droppables are in #companies (a table). Thanks! $(".draggable").draggable({ revert:true }); $(".droppable").droppable({ drop: function(ev, ui) { $(this).text($(ui.draggable).text()); $.post('planning/save_visit', {user_id: $(ui.draggable).attr('id'), company_id: $(this).attr('id'), period: $('ul.periods li.active').attr('id')}); $.post('planning/' + $('ul.periods li.active').attr('id'), {visitors:true}, function(data){ $('#visitors').html(data); }); }, hoverClass: 'drophover' });

• Avoid richfaces to send back javascript libraries in the ajax responses

  - by pakore

  I'm using JSF 1.2 with Richfaces, and for every ajax request, the server is sending back the response, whichi is good, but it also contains all the links to the javascript files. I want to improve the performance so I just want the <body> to be returned, because all the javascript files are already loaded in the browser when the user logs in (my app is not restful). How can i do that? Thanks This is an example of a response to reRender an image when clicking a button. <?xml version="1.0"?> <html lang="nl_NL" xmlns="http://www.w3.org/1999/xhtml"><head><title></title><link

• jQuery FullCalendar JSON date issue

  - by durilai

  I am integrating jQuery plugin FullCalendar, overall it has been really straightforward. I however have ran into a problem with adding events to the calendar. I am using ASP.NET MVC 1.0 and have found and followed this post. I am returning JSON to the FullCalendar and the events are getting bound, but they all show up as all day events. I am formatting the dates as ISO8601 format. Calendar Javascript $('#calendar').fullCalendar({ events: "/Calendar/GetEvents/" }); JsonResult public JsonResult GetEvents(double start, double end) { var fromDate = Utility.Dates.ConvertFromUnixTimestamp(start); var toDate = Utility.Dates.ConvertFromUnixTimestamp(end); List<GenericEventList> events = GETGENERICLISTOFEVENTS(); return Json(events.ToArray()); } JSON Result Value [{"id":2,"title":"Test Event","start":"2010-03-14T11:00:00","end":"2010-03-14T16:00:00"}, {"id":3,"title":"Test Event1asasas","start":"2010-03-14T10:00:00","end":"2010-03-14T14:00:00"}, {"id":4,"title":"Test Event12","start":"2010-03-14T16:00:00","end":"2010-03-14T17:00:00"}, {"id":6,"title":"Test Event1aaa","start":"2010-03-14T10:00:00","end":"2010-03-14T14:00:00"}] Any help is truly appreciated!
