• Improve the Quality of ePub eBooks with Sigil

  - by Matthew Guay

  Would you like to correct errors in your ePub formatted eBooks, or even split them into chapters and create a Table of Contents?  Here’s how you can with the free program Sigil. eBooks are increasingly popular with the rise of eBook readers and reading apps on mobile devices.  We recently showed you how to convert a PDF eBook to ePub format, but as you may have noticed, sometimes the converted file had some glitches or odd formatting.  Additionally, many of the many free ePub books available online from sources like the Project Guttenberg do not include a table of contents.  Sigil is a free application for Windows, OS X, and Linux that lets you edit ePub files, so let’s look at how you can use it to improve your eBooks. Note: Sigil took several moments to open files in our tests, and froze momentarily when we maximized the window.  Sigil is currently pre-release software in active development, so we would expect the bugs to be worked out in future versions.  As usual, only install if you’re comfortable testing pre-release software. Getting Started Download Sigil (link below), making sure to select the correct version for your computer.  Run the installer, and select your preferred setup language when prompted. After a moment the installer will appear; setup as normal. Launch Sigil when it’s finished installing.  It opens with a default blank ePub file, so you could actually start writing an eBook from scratch right here. Edit Your ePub eBooks Now you’re ready to edit your ePub books.  Click Open and browse to the file you want to edit. Now you can double-click any of the HTML or XHTML files on the left sidebar and edit them just like you would in Word. Or you can choose to view it in Code View and edit the actual HTML directly. The sidebar also gives you access to the other parts of the ePub file, such as Images and CSS styles. If your ePub file has a Table of Contents, you can edit it with Sigil as well.  Click Tools in the menu bar, and then select TOC Editor.  Strangely there is no way to create a new table of contents, but you can remove entries from existing one.   Convert TXT Files to ePub Many free eBooks online, especially older, out of copyright titles, are available in plain text format.  One problem with these files is that they usually use hard returns at the end of lines, so they don’t reflow to fill your screen efficiently. Sigil can easily convert these files to the more useful ePub format.  Open the text file in Sigil, and it will automatically reflow the text and convert it ePub.  As you can see in the screenshot below, the text in the eBook does not have hard line-breaks at the end of each line, and will be much more readable on mobile devices. Note that Sigil may take several moments opening the book, and may even become unresponsive while analyzing it.   Now you can edit your eBook, split it into chapters, or just save it as is.  Either way, make sure to select Save as to save your book as ePub format. Conclusion As mentioned before, Sigil seems to run slow at times, especially when editing large eBooks.  But it’s still a nice solution to edit and extend your ePub eBooks, and even convert plain text eBooks to the nicer ePub format.  Now you can make your eBooks work just like you want, and read them on your favorite device!

• How to familiarize myself with Python

  - by Zel

  I am Python beginner. Started Python 1.5 months back. I downloaded the Python docs and read some part of the tutorial. I have been programming on codechef.com and solving problems of projecteuler. I am thinking of reading Introduction to algorithms and following this course on MIT opencourse ware as I haven't been getting much improvement in programming and I am wasting much time thinking just what should I do when faced with any programming problem. But I think that I still don't know the correct way to learn the language itself. Should I start the library reference or continue with Python tutorial? Is learning algorithms useful for language such as C and not so much for Python as it has "batteries included"? Are there some other resources for familiarization with the language and in general for learning to solve programming problems? Or do I need to just devote some more time?

• Adding VFACE semantic causes overlapping output semantics error

  - by user1423893

  My pixel shader input is a follows struct VertexShaderOut { float4 Position : POSITION0; float2 TextureCoordinates : TEXCOORD0; float4 PositionClone : TEXCOORD1; // Final position values must be cloned to be used in PS calculations float3 Normal : TEXCOORD2; //float3x3 TBN : TEXCOORD3; float CullFace : VFACE; // A negative value faces backwards (-1), while a positive value (+1) faces the camera (requires ps_3_0) }; I'm using ps_3_0 and I wish to utilise the VFACE semantic for correct lighting of normals depending on the cull mode. If I add the VFACE semantic then I get the following errors: error X5639: dcl usage+index: position,0 has already been specified for an output register error X4504: overlapping output semantics Why would this occur? I can't see why there would be too much data.

• QT Creator 64-bit Snow Leopard

  - by quadelirus

  I have a bunch of libraries that I need to link against that I installed via macports. They are 64-bit libraries. I'm working on an application written with QT Creator and the .pro is set up. I downloaded the QT SDK for Mac OS X, but it is 32-bit and so the compiled code won't link against the 64-bit binaries that I got from macports. Ok. So I downloaded the QT SDK source and built from source using -arch x86_64. Now I have a 64-bit version of the SDK (I think) but it didn't build a QT Creator app. So. I need to know one of 4 things: Either, 1.) I'm guessing that a simple make command will convince the QT SDK to build the creator for me. If this is true, then what is the command (make creator?). barring that, I need to know 2.) The easiest way to get MacPorts to redownload the libraries that I installed with a 32-bit version (I keep seeing a "+universal" mentioned, but I haven't seen it on a line, and simply calling ports +universal install XYZ doesn't seem to work--perhaps I need to uninstall and reinstall the package?). Also, is this a stupid idea? or 3.) Someone who actually has a prebuilt 64-bit QT SDK installer so I don't have to mess with this. It is ridiculous that QT doesn't already have this available, in my opinion--SL has been out since, what, last August? 4--and this would take the cake.) I don't understand why I can't simply put a "compile-for-64-bit stupid" command directly into the QT pro file and have it build. There isn't really a reason why a compiler compiled in 32-bits couldn't compile to 64-bits is there? Thanks.

• Animations in FBX exported from Maya are anchored in the wrong place

  - by Simon P Stevens

  We are trying to export a model and animation from Maya into Unity3d. In Maya, the model is anchored (pivot point) at the feet (and the body moves up and down). However after we have performed the FBX export, and imported the file into Unity the model is now appears to be anchored by the waist/head and the feet move. These example videos probably help explain the problem more clearly: Example video - Maya - Correct Example video - Unity - Wrong We have also noticed that if we take the FBX file and import it back into Maya we have exactly the same problem. It seems to be that the constraints no longer work after the FBX is reimported back to Maya, which just kills the connection between the joints and the control objects. When we exported the FBX we have tried checking the 'bake animations' check box. The fact that the same problem exist when importing the FBX back into both Maya and Unity suggests that the source of the problem is most likely with the Maya FBX export. Has anyone encountered this problem before and have any ideas how to fix it?

• Flex SDK the right tool for this project

  - by RWAC

  A client wants a site similar to this one (but different purpose): http://www.spokeo.com/search?q=Samantha+Dawes,+&s7=t30 where the user searches by name and a map is displayed with the count over each state. When the user clicks the count the list is displayed. I am a PHP developer (and have experience with C, C++, etc). Would Flex SDK, Flash Builder 4.5 for PHP, or Flash be the best tool? The Flex SDK http://www.adobe.com/products/flex.html looks promising and it looks like I can download it free without having to purchase Flash or Flex. Is that correct? Do you think this kind of project can be done with the Flex SDK? Without purchasing Flex or Flash? Thank you for taking the time to read this.

• NTFS Issues in Windows 7 and 2008 R2 - 'Is it a Bug?'

  - by renewieldraaijer

  I have been using the various versions of the Microsoft Windows product line since NT4 and I really thought I knew the ins and outs about the NTFS filesystem by now. There were always a few rules of thumb to understand what happens if you move data around. These rules were: "If you copy data, the copied data will inherit the permissions of the location it is being copied to. The same goes for moving data between disk partitions. Only when you move data within the same partition, the permissions are kept."  Recently I was asked to assist in troubleshooting some NTFS related issues. This forced me to have another good look at this theory. To my surprise I found out that this theory does not completely stand anymore. Apparently some things have changed since the release of Windows Vista / Windows 2008. Since the release of these Operating Systems, a move within the same disk partition results in the data inheriting the permissions of the location it is being copied into. A major change in the NTFS filesystem you would think!  Not quite! The above only counts when the move operation is being performed by using Windows Explorer. A move by using the 'move' command from within a cmd prompt for example, retains the NTFS permissions, just like before in Windows XP and older systems. Conclusion: The Windows Explorer is responsible for changing the ACL's of the moved data. This is a remarkable change, but if you follow this theory, the resulting ACL after a move operation is still predictable.  We could say that since Windows Vista and Windows 2008, a new rule set applies: "If you copy data, the copied data will inherit the permissions of the location it is being copied to. Same goes for moving data between disk partitions and within disk partitions. Only when you move data within the same partition by using something else than the Windows Explorer, the permissions are kept." The above behavior should be unchanged in Windows 7 / Windows 2008 R2, compared to Windows Vista / 2008. But somehow the NTFS permissions are not so predictable in Windows 7 and Windows 2008 R2. Moving data within the same disk partition the one time results in the permissions being kept and the next time results in inherited permissions from the destination location. I will try to demonstrate this in a few examples: Example 1 (Incorrect behavior): Consider two folders, 'Folder A' and 'Folder B' with the following permissions configured.                    Now we create the test file 'test file 1.txt' in 'Folder A' and afterwards move this file to 'Folder B' using Windows Explorer.                       According to the new theory, the file should inherit the permissions of 'Folder B' and therefore 'Group B' should appear in the ACL of 'test file 1.txt'. In the screenshot below the resulting permissions are displayed. The permissions from the originating location are kept, while the permissions of 'Folder B' should be inherited.                   Example 2 (Correct behavior): Again, consider the same two folders. This time we make a small modification to the ACL of 'Folder A'. We add 'Group C' to the ACL and again we create a file in 'Folder A' which we name 'test file 2.txt'.                    Next, we move 'test file 2.txt' to 'Folder B'.                       Again, we check the permissions of 'test file 2.txt' at the target location. We can now see that the permissions are inherited. This is what should be happening, and can be considered 'correct behavior' for Windows Vista / 2008 / 7 / 2008 R2. It remains uncertain why this behavior is so inconsistent. At this time, this is under investigation with Microsoft Support. The investigation has been going for the last two weeks and it is beginning to look like there is no rational reason for this, other than a bug in the Windows Explorer in Windows 7 and 2008 R2. As soon as there is any certainty on this, I will note it here in this blog.                   The examples above are harmless tests, by using my own laptop. If you would create the same set of folders and groups, and configure exactly the same permissions, you will see exactly the same behavior. Be sure to use Windows 7 or Windows 2008 R2.   Initially the problem arose at a customer site where move operations on data on the fileserver by users would result in unpredictable results. This resulted in the wrong set of people having àccess permissions on data that they should not have permissions to. Off course this is something we want to prevent at all costs.   I have also done several tests with move operations by using the move command in a cmd prompt. This way the behavior is always consistent. The inconsistent behavior is only exposed when using the Windows Explorer to initiate the move operation, and only when using Windows 7 or Windows 2008 R2 systems. It is evident that this behavior changes when the ACL of a folder has been changed, for example by adding an extra entry. The reason for this remains uncertain though. To be continued….

• Starting a career with broad experience or specific experience

  - by TMP

  I am a senior in college going for a CS degree. I have an internship that works with a variety of languages and gives me a pretty good amount of responsibility. The only problem is that it is the only job experience I've had. My question is whether or not it might be a good idea to work another internship, keep the same internship, or in addition to the previous options, to get a masters degree so that i can extend my education and time to gather the usually necessary 2-3 years of industry experience. Obviously there's no outright correct way, but i just want to know if it is more accepted to get experience with different companies or to stick with one to show commitment.

• Where to go after Adobe Flex? [closed]

  - by jan halfar

  After this post http://blogs.adobe.com/flex/2011/11/your-questions-about-flex.html and especially this paragraph: ... Does Adobe recommend we use Flex or HTML5 for our enterprise application development? In the long-term, we believe HTML5 will be the best technology for enterprise application development. We also know that, currently, Flex has clear benefits for large-scale client projects typically associated with desktop application profiles. ... Make no mistake, the days of Flex are over. Thus a lot of people are asking themselves: Which technology(ies) will solve their and their customers problems in a future without flex? P.S.: Obviously the correct answer for adobe would have been " ...Since we believe, that HTML5 will be the best technology enterprise application development, we will ensure that it will be targeted by future releases of the Flex framework ..."

• Ardour won't rewind when jack time master

  - by Edward

  Using Ubuntu Studio 12.04, ardour will not rewind when it is set to the jack time master. I've read that this could be due to a jack/ardour version conflict, but I am not sure what the correct combo should be. The same thing happens with "ardour 2.8.14 (built from revision 13065)" and "ardour 2.8.12 (built from revision 10144)". The latter is the default installation with ubuntu studio 12.04 LTS. Linux "/proc/version" reports as Linux version 3.2.0-23-lowlatency-pae (buildd@vernadsky) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #31-Ubuntu SMP PREEMPT Wed Apr 11 04:07:36 UTC 2012 and "jackd --version" reports as: jackdmp 1.9.8 Copyright 2001-2005 Paul Davis and others.

• JQuery and the multiple date selector

  - by David Carter

  Overview I recently needed to build a web page that would allow a user to capture some information and most importantly select multiple dates. This functionality was core to the application and hence had to be easy and quick to do. This is a public facing website so it had to be intuitive and very responsive. On the face of it it didn't seem too hard, I know enough juery to know what it is capable of and I was pretty sure that there would be some plugins that would help speed things along the way. I'm using ASP.Net MVC for this project as I really like the control that it gives you over the generated html and javascript. After years of Web Forms development it makes me feel like a web developer again and puts a smile on my face, that can only be a good thing!   The Calendar The first item that I needed on this page was a calender and I wanted the ability to: have the calendar be always visible select/deselect multiple dates at the same time bind to the select/deselect event so that I could update a seperate listing of the selected dates allow the user to move to another month and still have the calender remember any dates in the previous month I was hoping that there was a jQuery plugin that would meet my requirements and luckily there was! The jQuery datepicker does everything I want and there is quite a bit of documentation on how to use it. It makes use of a javascript date library date.js which I had not come across before but has a number of very useful date utilities that I have used elsewhere in the project. As you can see from the image there still needs to be some styling done! But there will be plenty of time for that later. The calendar clearly shows which dates the user has selected in red and i also make use of an unordered list to show the the selected dates so the user can always clearly see what has been selected even if they move to another month on the calendar. The javascript code that is responsible for listening to events on the calendar and synchronising the list look as follows: <script type="text/javascript">     $(function () {         $('.datepicker').datePicker({ inline: true, selectMultiple: true })         .bind(             'dateSelected',             function (e, selectedDate, $td, state) {                                 var dateInMillisecs = selectedDate.valueOf();                 if (state) { //adding a date                     var newDate = new Date(selectedDate);                     //insert the new item into the correct place in the list                     var listitems = $('#dateList').children('li').get();                     var liToAdd = "<li id='" + dateInMillisecs + "' >" + newDate.toString('ddd dd MMM yyyy') + "</li>";                     var targetIndex = -1;                     for (var i = 0; i < listitems.length; i++) {                         if (dateInMillisecs <= listitems[i].id) {                             targetIndex = i;                             break;                         }                     }                     if (targetIndex < 0) {                         $('#dateList').append(liToAdd);                     }                     else {                         $($('#dateList').children("li")[targetIndex]).before(liToAdd);                     }                 }                 else {//removing a date                     $('ul #' + dateInMillisecs).remove();                 }             }         )     }); When a date is selected on the calendar a function is called with a number of parameters passed to it. The ones I am particularly interested in are selectedDate and state. State tells me whether the user has selected or deselected the date passed in the selectedDate parameter. The <ul> that I am using to show the date has an id of dateList and this is what I will be adding and removing <li> items from. To make things a little more logical for the user I decided that the date should be sorted in chronological order, this means that each time a new date is selected it need to be placed in the correct position in the list. One way to do this would be just to append a new <li> to the list and then sort the whole list. However the approach I took was to get an array of all the items in the list var listitems = ('#dateList').children('li').get(); and then check the value of each item in the array against my new date and as soon as I found the case where the new date was less than the current item remember that position in the list as this is where I would insert it later. To make this work easily I decided to store a numeric representation of each date in the list in the id attribute of each <li> element. Fortunately javascript natively stores dates as the number of milliseconds since 1 Jan 1970. var dateInMillisecs = selectedDate.valueOf(); Please note that this is the value of the date in UTC! I always like to store dates in UTC as I learnt a long time ago that it saves a lot of refactoring at a later date... When I convert the dates back to their original back on the server I will need the UTC offset that was used when calculating the dates, this and how to actually serialise the dates and get them posted back will be the subject of another post.

• How do I set up a virtual network interface with its own IP address?

  - by Stefano Palazzo

  I vaguely remember that it's possible to set up virtual network interfaces with their own IP addresses, using only one physical network connection. I can find a few guides on the internet that recommend setting these up in /etc/network/interfaces, but Ubuntu doesn't use this file. Therefore my question: What's the correct way of setting these up in recent versions of Ubuntu? As this is a laptop, and I need it to connect to all kinds of different networks, I want to keep the network manager and all its configuration. To be more clear: at the end of this, I want to have a new network interface (e.g. "eth42") with its own IP address, but using whatever is connected in network manager to send the actual packets. In NM, it should appear as if I just had a second ethernet adapter installed in my system.

• Apache directory structure with multiple hosted languages.

  - by anomareh

  I just got a new work machine up and running and I'm trying to decide on how to set everything up directory wise. I've done some digging around and really haven't been able to find anything conclusive. I know it's a question with a variety of answers but I'm hoping there's some sort of general guidelines or best practices to go by. With that said, here are a few things specific to my situation. I will be doing actual development and testing on the same machine as the server. It is a single user machine in the sense that I will be the only one working on the machine. There will be multiple hosted languages, specifically PHP and RoR while possibly expanding later. I'd like the setup to translate well to a production environment. With those 3 things in mind there are a couple of things I've had in the back of mind. Seeing as it's a single user machine I haven't been able to decide whether or not I should be working on things out of my home directory or if they should be located outside of it. I'm feeling that outside of a user directory would be better as it would translate better to a production environment, but I'm also not sure if that will come with any permission annoyances or concerns seeing as I'll be working on the same machine. Hosting multiple languages seems like it may be a bit quirky. With PHP I've found you're generally just dumping the project somewhere in the document root where as something like a Rails app you have the entire project and you only want the public directory in the document root. Thanks for any insight, opinion, or just personal preference from experience anyone can offer.

• Virtualbox: host only networking - proxy internet connection

  - by Russell

  I'll ask my question first, then give details about where I am coming from: Is it possible to use host only, then have ubuntu act as a proxy to provide internet access to windows? If so, how? I am trying to get the right combination of networking for my virtualbox windows client VM (win7). My host is ubuntu 10.10 (maverick). I believe I understand the basic network options (please correct me if I am incorrect): NAT - Host can't communicate with guest but guest has access to all host's adapters Host only - Separate adapter but guest has no net access Bridged - bridge an adapter in the host with the virtual adapter to give the host access to the host adapter I am trying to give my win guest internet access, but also access the host in a separate network. Bridged only works when the host is connected to the internet (this is a laptop) so when it's not connected the network is down. Thanks I appreciate your help.

• Internal Use Chat/Desktop Platform

  - by Malnizzle

  I did some looking, but I didn't see a SF question directly related to this. I need to find a platform for internal/LAN use only for chat and desktop sharing. We got a lot people having to get up and walk over to another person's office for simple items, and we could save a lot of time collectivity if we had a solution where we had a client app similar to gchat or AIM, where one could right click a name and request a desktop sharing session (to or from). This wouldn't be for product presentation or long training sessions, and wouldn't need more than 2 people in the session. We use GoToMeeting for this. I've looked at TeamViewer, and they got the features I want (plus a lot more features that wouldn't help) and seem more geared to large enterprise support, and it is not exactly cheap. Also looked at OCS some as well, but it seems heavy for what I am trying to do. I don't need anything relating to phone usage. If the general opinion says otherwise, I could talked back into OCS if I am wrong about weight of the product. We use GoToAssist for remote support of clients (which I am a fan of), and I don't it fits here, correct me if I am wrong. All the workstations are XP/7. Thanks!

• Uploading to a PPA using quickly

  - by Andres

  I am trying to participate in ubuntu showdown. I followed Jono's tutorial to do a browser using quickly. I did some modifications including choosing license (gpl v3), putting my name in copy right ( without special spanish charecters since quicky does not like it) $quickly run to make sure it worked I used bazaar to commit a change with a line of comment. I packaged it using quickly. Managed to install it ignoring some warnings but it would not run. I want to share code to get feedback. I have a launchpad account, signed terms and coditions, created a ppa. I got my commandline to talk to lauchpad using the encription key. But when I run $quickly release or $quickly share and it says the project does not exist. There seems to be another command $dput ... But i don't seem to get the wording right because it requests some sort of signed file that i cannot manage to add the correct way.

This is how my code looks like: echo "STEP 8: CREATE STOP SCRIPT" stopScriptContent="echo \"STOPING GLASSFISH PLEASE WAIT...\"\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n" ${stopScriptContent} > stop.sh chmod +x stop.sh But it is not being created correctly, this is how the output stop.sh looks like: "STOPING GLASSFISH PLEASE WAIT..."\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n As you see, lots of things are wrong: there is no echo command is taking the \n literaly so there is no new line My doubts are: What is the correct way of making an .sh script create another .sh script.

• Convert a Linksys WAG54GP2 ADSL router into Access point only to extend my Wifi range

  - by Preet Sangha

  I have a wireless lan running on my ASDL2 connection. The router (Seimens Gigaset sx763) is provided by the ISP and is generally good. However I have couple of dead spots at the far end of the house and since I have my old router sitting in the drawer I thought that I'd try to convert it into simple WAP. However downloading the manual from linksys it seems to be that the manual is from an earlier firmware, but the very first option on the very first page seems promising: Wan Mode: Router or ADSL However after this I'm a bit lost. I know that the wireless card on this box will need a mac address and it must get its address from the master router (I thought static might be best). However the again the manual is out of date I have the option of DHCP: ON or OFF or RELAY I've not even got to the more complex options yet. Question is can this device even work this way (seems like it but I cannot find any docs on it), and if so how? Edit: Having now fiddled around I'm of the opinion that this cannot be done.

• how to properly credit authors of MIT license program

  - by kon psych

  Although I have found similar questions on this site they were not what I was looking for. I have modified the source code of an MIT licensed project, and I have added new classes to it as well. Please correct me if I am wrong, but I think that it is legal to add my copyright notice above the license and remove the other one. But how should I attribute the contribution of the previous authors? Should I use a separate file? There are also some html files with no license or copyright notice in them which I also modified. Do I have to handle them differently? My question is different than this question in that I have also modified some of the files of the project I am extending.

• Advanced donut caching: using dynamically loaded controls

  - by DigiMortal

  Yesterday I solved one caching problem with local community portal. I enabled output cache on SharePoint Server 2007 to make site faster. Although caching works fine I needed to do some additional work because there are some controls that show different content to different users. In this example I will show you how to use “donut caching” with user controls – powerful way to drive some content around cache. About donut caching Donut caching means that although you are caching your content you have some holes in it so you can still affect the output that goes to user. By example you can cache front page on your site and still show welcome message that contains correct user name. To get better idea about donut caching I suggest you to read ScottGu posting Tip/Trick: Implement "Donut Caching" with the ASP.NET 2.0 Output Cache Substitution Feature. Basically donut caching uses ASP.NET substitution control. In output this control is replaced by string you return from static method bound to substitution control. Again, take a look at ScottGu blog posting I referred above. Problem If you look at Scott’s example it is pretty plain and easy by its output. All it does is it writes out current user name as string. Here are examples of my login area for anonymous and authenticated users:    It is clear that outputting mark-up for these views as string is pretty lame to implement in code at string level. Every little change in design will end up with new version of controls library because some parts of design “live” there. Solution: using user controls I worked out easy solution to my problem. I used cache substitution and user controls together. I have three user controls: LogInControl – this is the proxy control that checks which “real” control to load. AnonymousLogInControl – template and logic for anonymous users login area. AuthenticatedLogInControl – template and logic for authenticated users login area. This is the control we render for each user separately because it contains user name and user profile fill percent. Anonymous control is not very interesting because it is only about keeping mark-up in separate file. Interesting parts are LogInControl and AuthenticatedLogInControl. Creating proxy control The first thing was to create control that has substitution area where “real” control is loaded. This proxy control should also be available to decide which control to load. The definition of control is very primitive. <%@ Control EnableViewState="false" Inherits="MyPortal.Profiles.LogInControl" %> <asp:Substitution runat="server" MethodName="ShowLogInBox" /> But code is a little bit tricky. Based on current user instance we decide which login control to load. Then we create page instance and load our control through it. When control is loaded we will call DataBind() method. In this method we evaluate all fields in loaded control (it was best choice as Load and other events will not be fired). Take a look at the code. public static string ShowLogInBox(HttpContext context) {     var user = SPContext.Current.Web.CurrentUser;     string controlName;       if (user != null)         controlName = "AuthenticatedLogInControl.ascx";     else         controlName = "AnonymousLogInControl.ascx";       var path = "~/_controltemplates/" + controlName;     var output = new StringBuilder(10000);       using(var page = new Page())     using(var ctl = page.LoadControl(path))     using(var writer = new StringWriter(output))     using(var htmlWriter = new HtmlTextWriter(writer))     {         ctl.DataBind();         ctl.RenderControl(htmlWriter);     }     return output.ToString(); } When control is bound to data we ask to render it its contents to StringBuilder. Now we have the output of control as string and we can return it from our method. Of course, notice how correct I am with resources disposing. :) The method that returns contents for substitution control is static method that has no connection with control instance because hen page is read from cache there are no instances of controls available. Conclusion As you saw it was not very hard to use donut caching with user controls. Instead of writing mark-up of controls to static method that is bound to substitution control we can still use our user controls.

• Google Chrome user agent, wrong language

  - by B. Roland

  Hello! After some months, my Chrome(now 10.0.648.127 beta; but I tried with the lastest stable too) displayed some popular sites in English, instead of my Chrome & system language, which is Hungarian... I saw my User-Agent, which shows in Chrome: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.127 Safari/534.16 But in Firefox: Mozilla/5.0 (X11; U; Linux i686; hu-HU; rv:1.9.2.15) Gecko/20110303 Ubuntu/10.04 (lucid) Firefox/3.6.15, what is correct... My question is: How can I change my user-agent(maybe dynamically, by version)? I tried with google-chrome --user-agent "text", but it failed in the newest versions.

• How do I Fix SQL Server error: Order by items must appear in the select list if Select distinct is s

  - by Paula DiTallo 2007-2009 All Rights Reserved

  There's more than one reason why you may receive this error, but the most common reason is that your order by statement column list doesn't correlate with the values specified in your column list when you happen to be using DISTINCT. This is usually easy to spot and resolve. A more obscure reason may be that you are using a function around one of the selected columns --but omitting to use the same function around the same selected column name in the order by statement. Here's an example:   select distinct upper(columnA)   from [evaluate].[testTable]    order by columnA  asc   This statement will cause the "Order by items must appear in the select list if SELECT DISTINCT is specified."  error to appear not because distinct was used, but because the order by statement did not utilize the upper() fundtion around colunnA.  To correct this error, do this: select distinct upper(columnA)   from [evaluate].[testTable]    order by upper(columnA) asc

• HP Deskjet 720C USB printer doesn't finish

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the last page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. EDIT: It seems like the problem is with the last page. So if I am printing 3 pages, the first two work well but the last few lines in the last page are not printed. Any ideas?
