  • Which Single Source Publishing tools and strategies are available?

    - by Another Registered User
    I'm about to write a 1000-Pages Documentation about a huge programming framework. The goal is to bring this documentation online into an web platform, so that online users can search through it and read it online. At the same time, the text has to be made public in PDF format for download. And at the same time, the whole thing needs to go into a printed book as well (print on demand, they want a giant PDF file with the whole book). The PDF files: The whole content is divided into several chapters. Every chapter will be available as a standalone PDF eBook. And finally, all chapters will be available in one huge printed book. Is LaTeX capable for something like that? Can it be used for Single Source Publishing? Or would I have to take a look at other technologies like DocBook, etc.?

  • How to force Chrome to make bookmarks the priority for auto-complete in the address bar?

    - by NoCatharsis
    As it is right now, if I start typing, for instance, "dictionary" into the address bar, Chrome immediately returns a list of bookmarks, history, and related sites. However, the first and highlighted option is to search Google for "dictionary". I want Chrome to immediately recognize that I have a bookmark specifically named "Dictionary" that links to the site www.dictionary.com. But, that's the second choice, not the first. So I have to type a few letters, get auto-complete to suggest some sites, then key down to my bookmark item before pressing Enter. How annoying. Any way to cut the middle man and make my bookmark the top result?

  • Tools of the Trade

    - by Ajarn Mark Caldwell
    I got pretty excited a couple of days ago when my new laptop arrived. “The new phone books are here!  The new phone books are here!  I’m a somebody!” - Steve Martin in The Jerk It is a Dell Precision M4500 with an Intel i7 Core 2.8 GHZ running 64-bit Windows 7 with a 15.6” widescreen, 8 GB RAM, 256 GB SSD.  For some of you high fliers, this may be nothing to write home about, but compared to the 32–bit Windows XP laptop with 2 GB of RAM and a regular hard disk that I’m coming from, it’s a really nice step forward.  I won’t even bore you with the details of the desktop PC I was first given when I started here 5 1/2 years ago.  Let’s just say that things have improved.  One really nice thing is that while we are definitely running a lean and mean department in terms of staffing, my boss believes in supporting that lean staff with good tools in order to stay lean instead of having to spend even more money on additional employees.  Of course, that only goes so far, and at some point you have to add more people in order to get more work done, which is why we are bringing on-board a new employee and a new contract developer next week.  But that’s a different story for a different time. But the main topic for this post is to highlight the variety of tools that I use in my job and that you might find useful, too.  This is easy to do right now because the process of building up my new laptop from scratch has forced me to assemble a list of software that had to be installed and configured.  Keep in mind as you look through this list that I play many roles in our company.  My official title is Software Engineering Manager, but in addition to managing the team, I am also an active ASP.NET and SQL developer, the Database Administrator, and 50% of the SAN Administrator team.  So, without further ado, here are the tools and some comments about why I use them: Tool Purpose Virtual Clone Drive Easily mount an ISO image as a DVD Drive.  This is particularly handy when you are downloading disk images from Microsoft for your tools. SQL Server 2008 R2 Developer Edition We are migrating all of our active systems to SQL 2008 R2.  Developer Edition has all the features of Enterprise Edition, but intended for development use. SQL Server 2005 Developer Edition (BIDS ONLY) The migration to SSRS 2008 R2 is just getting started, and in the meantime, maintenance work still has to be done on the reports on our SQL 2005 server.  For some reason, you can’t use BIDS from 2008 to write reports for a 2005 server.  There is some different format and when you open 2005 reports in 2008 BIDS, it forces you to upgrade, and they can no longer be uploaded to a 2005 server.  Hopefully Microsoft will fix this soon in some manner similar to Visual Studio now allows you to pick which version of the .NET Framework you are coding against. Visual Studio 2010 Premium All of our application development is in ASP.NET, and we might as well use the tool designed for it. I’ve used a version of Visual Studio going all the way back to VB 6.0 and Visual Interdev. Vault Professional Client Several years ago we replaced Visual Source Safe with SourceGear Vault (then Fortress, and now Vault Pro), and I love it.  It is very reliable with low overhead - perfect for a small to medium size development team.  And being a small ISV, their support is exceptional. Red-Gate Developer Bundle with the SQL Source Control update for Vault I first used, and fell in love with, SQL Prompt shortly before Red-Gate bought it, and then Red-Gate’s first release made me love it even more.  SQL Refactor (which has since been rolled into the latest version of SQL Prompt) has saved me many hours and migraine’s trying to understand somebody else’s code when their indenting was nonexistant, or worse, irrational.  SQL Compare has been awesome for troubleshooting potential schema issues between different instances of system databases.  SQL Data Compare helped us identify the cause behind a bug which appeared in PROD but could not be reproduced in a nearly (but not quite exactly) identical copy in UAT.  And the newest tool we are embracing: SQL Source Control.  I blogged about it here (and here, and here) last December.  This is really going to help us keep each developer’s copy of the database in sync with one another. Fiddler Helps you watch the whole traffic stream on web visits.  Haven’t used it a lot, but it did help me track down some odd 404 errors we were finding in our own application logs.  Has some other JavaScript troubleshooting capabilities, but some of its usefulness has been supplanted by the Developer Tools option in IE8. Funduc Search & Replace Find any string anywhere in a mound of source code really, really fast.  Does RegEx searches, if you understand that foreign language.  Has really helped with some refactoring work to pinpoint, for example, everywhere a particular stored procedure is referenced, whether in .NET code or other SQL procedures (which we have in script files).  Provides in-context preview of the search results.  Fantastic tool, and a bargain price. SciTE SciTE is a Scintilla based Text Editor and it is a fantastic, light-weight tool for quickly reviewing (or writing) program code, SQL scripts, and extract files.  It has language-specific syntax highlighting.  I used it to write several batch and CMD programs a year ago, and to examine data extract files for exchanging information with other systems.  Extremely handy are the options to View End of Line and View Whitespace.  Ever receive a file that is supposed to use CRLF as an end-of-line marker, but really only has CRs?  SciTE will quickly make that visible. Infragistics Controls We do a lot of ASP.NET development, and frequently use the WebGrid, WebTab, and date picker controls.  We will likely be implementing the Hierarchical Data Grid soon.  Infragistics has control suites for WebForms, WinForms, Silverlight, and coming soon MVC/JQuery. WinZip - WITH Command-Line add-in The classic compression program with a great command-line interface that allows me to build those CMD (and soon PowerShell) programs for automated compression jobs.  Our versioned Build packages are zip files. XML Notepad Haven’t used this a lot myself, but one of my team really likes it for examining large XML files. LINQPad Again, haven’t used this one a lot, but it was recommended to me for learning and practicing my LINQ skills which will come in handy as we implement Entity Framework. SQL Sentry Plan Explorer SQL Server Show Plan on steroids.  Great for helping you focus on the parts of a large query that are of most importance.  Also great for just compressing the graphical plan into more readable layout. Araxis Merge A great DIFF and Merge tool.  SourceGear provides a great tool called DiffMerge that we use all the time, but occasionally, I like the cross-edit capabilities of Araxis Merge.  For a while, we also produced DIFF reports in HTML that showed all the changes that occurred between two releases.  This was most important when we were putting out very small, but very important hot fixes on a very politically hot system.  The reports produced by Araxis Merge gave the Director of IS assurance that we were not accidentally introducing ripples throughout the system with our releases. Idera SQL Admin Toolset A great collection of tools including a password checker to help analyze your SQL Server for weak user passwords, a Backup Status tool to quickly scan a large list of servers and databases to identify any that are overdue for backups.  Particularly helpful for highlighting new databases that have been deployed without getting included in your backup processing.  I also like Space Analyzer to keep an eye on disk space consumed by database files. Idera SQL Job Manager This free tool provides a nice calendar view of SQL Server Job Schedules, but to a degree, you also get what you pay for.  We will be purchasing SQL Sentry Event Manager later this year as an even better job schedule reviewer/manager.  But in the meantime, this at least gives me a good view on potential resource conflicts across multiple instances of SQL Server. DBFViewer 2000 I inherited a couple of FoxPro databases that I have to keep an eye on occasionally and have not yet been able to migrate them to SQL Server. Balsamiq Mockups We are still in evaluation-mode on this tool, but I really like it as a quick UI mockup tool that does not require Visual Studio, so someone other than a programmer can do UI design.  The interface looks hand-drawn which definitely has some psychological benefits when communicating to users, too. FeedDemon I have to stay on top of my WAY TOO MANY blog subscriptions somehow.  I may read blogs on a couple of different computers, and FeedDemon’s integration with Google Reader allows me to keep them all in sync.  I don’t particularly like the Google Reader interface, or the fact that it always wanted to mark articles as read just because I scrolled past them.  FeedDemon solves this problem for me, and provides a multi-tabbed interface which is good because fairly frequently one blog will link to something else I want to read, and I can end up with a half-dozen open tabs all from one article. Synergy+ In my office, I run four monitors across two computers all with one mouse and keyboard.  Synergy is the magic software that makes this work. TweetDeck I’m not the most active Tweeter in the world, but when I want to check-in with the Twitterverse, this really helps.  I have found the #sqlhelp and #PoshHelp hash tags particularly useful, and I also have columns setup to make it easy to monitor #sqlpass, #PASSProfDev, and short term events like #sqlsat68.   Whew!  That’s a lot.  No wonder it took me a couple of days to get everything setup the way I wanted it.  Oh, that and actually getting some work accomplished at the same time.  Anyway, I know that is a huge dump of info, and most people never make it here to the end, so for those who did, let me say, CONGRATULATIONS, you made it! I hope you’ll find a new tool or two to make your work life a little easier.

    - by Manish
    I have a Server.exe file which I use to connect to a mac.(I am fairly confident that server.exe is not buggy ).When i try to do this I get this often cited error "No connection could be made because the target machine actively refused it " I did search some existing questions about this on the forum and it looked like this might be a firewall issue.FWIW I dont have any firewall set on my mac (client) and on my server machine (Windows 7 64 bit ) under the firewall settings I have :- Incoming connections : Block all connections to programs that are not on the list of allowed programs. Active Domain Networks: Same domain as the one which my client is on. Windows Firewire State: Off. Do you think i need to change something here?Can someone help me with next steps?

  • How to solve package issues/dependencies

    - by Wolfgang Kuehne
    Background info I am trying to install Veins simulation environment by following the tutorial provided by the author. In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal: sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev When I execute this command, I immediately get: E: Package 'proj' has no installation candidate Then I remove the proj from the command and execute it again without proj in it, next I get: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages. To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager. libgdal1-dev I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further? proj What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this What should I do to make sure that this simulation tool works fine?

  • What is the best memory supported by Asus Rampage Formula (1) motherboard

    - by James
    I'm rebuilding a PC from old components I have and I want to know what are the best ram sticks for the Asus Rampage Formula (The first motherboard in the Rampage Formula range) According to the Asus website (HERE) the maximum supported memory is 8GB but when I search through the memory compatibility list there's nothing above 2046mb and the motherboard only supports single or dual-channel memory. Can anyone point me in the direction of a more comprehensive list of compatible memory? Or does anyone know where I can ask about memory compatibility? Note: As far as I know, this model motherboard is no longer in production.

  • No device file for partition on logical volume (Linux LVM)

    - by Brian
    I created a logical volume (scandata) containing a single ext3 partition. It is the only logical volume in its volume group (case4t). Said volume group is comprised by 3 physical volumes, which are three primary partitions on a single block device (/dev/sdb). When I created it, I could mount the partition via the block device /dev/mapper/case4t-scandatap1. Since last reboot the aforementioned block device file has disappeared. It may be of note -- I'm not sure -- that my superior (a college professor) had prompted this reboot by running sudo chmod -R [his name] /usr/bin, which obliterated all suid in its path, preventing the both of us from sudo-ing. That issue has been (temporarily) rectified via this operation. Now I'll cut the chatter and get started with the terminal dumps: $ sudo pvs; sudo vgs; sudo lvs Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Scanning for physical volume names PV VG Fmt Attr PSize PFree /dev/sdb1 case4t lvm2 a- 819.32G 0 /dev/sdb2 case4t lvm2 a- 866.40G 0 /dev/sdb3 case4t lvm2 a- 47.09G 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" VG #PV #LV #SN Attr VSize VFree case4t 3 1 0 wz--n- 1.69T 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all logical volumes LV VG Attr LSize Origin Snap% Move Log Copy% Convert scandata case4t -wi-a- 1.69T Wiping internal VG cache $ sudo vgchange -a y Logging initialised at Sat Jan 8 11:43:14 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" 1 logical volume(s) in volume group "case4t" already active 1 existing logical volume(s) in volume group "case4t" monitored Found volume group "case4t" Activated logical volumes in volume group "case4t" 1 logical volume(s) in volume group "case4t" now active Wiping internal VG cache $ ls /dev | grep case4t case4t $ ls /dev/mapper case4t-scandata control $ sudo fdisk -l /dev/case4t/scandata Disk /dev/case4t/scandata: 1860.5 GB, 1860584865792 bytes 255 heads, 63 sectors/track, 226203 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00049bf5 Device Boot Start End Blocks Id System /dev/case4t/scandata1 1 226203 1816975566 83 Linux $ sudo parted /dev/case4t/scandata print Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/case4t-scandata: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1861GB 1861GB primary ext3 $ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1860.5 GB, 1860593254400 bytes 255 heads, 63 sectors/track, 226204 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000081 Device Boot Start End Blocks Id System /dev/sdb1 1 106955 859116006 83 Linux /dev/sdb2 113103 226204 908491815 83 Linux /dev/sdb3 106956 113102 49375777+ 83 Linux Partition table entries are not in disk order $ sudo parted /dev/sdb print Model: DELL PERC 6/i (scsi) Disk /dev/sdb: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 880GB 880GB primary reiserfs 3 880GB 930GB 50.6GB primary 2 930GB 1861GB 930GB primary I find it a bit strange that partition one above is said to be reiserfs, or if it matters -- it was previously reiserfs, but LVM recognizes it as a PV. To reiterate, neither /dev/mapper/case4t-scandatap1 (which I had used previously) nor /dev/case4t/scandata1 (as printed by fdisk) exists. And /dev/case4t/scandata (no partition number) cannot be mounted: $sudo mount -t ext3 /dev/case4t/scandata /mnt/new mount: wrong fs type, bad option, bad superblock on /dev/mapper/case4t-scandata, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so All I get on syslog is: [170059.538137] VFS: Can't find ext3 filesystem on dev dm-0. Thanks in advance for any help you can offer, Brian P.S. I am on Ubuntu GNU/Linux 2.6.28-11-server (Jaunty) (out of date, I know -- that's on the laundry list).

  • NetBSD as VMware workstation guest: `startx` hangs and maxes all CPUs utilization

    - by Howard Guo
    I am using VMware workstation 8. I have attempted to install and run NetBSD 5.1.2 and 6.0. Installations all went OK and the system was usable until I install a window manager. After installed xfce4, in NetBSD 5.1.2, I could startx and used xfce4 two times, however consecutive startx will hang and max all CPU to 100%. In NetBSD 6.0 RC2, I could not even start xfce4 once, startx hangs and max all CPU to 100%. I have tried to use both vmwlegacy and vmware device drivers, they don't help. I have also tried both 32bit and 64bit NetBSD, they behave in the same way. I also tried to catch the output of startx, however system was already hanging before the output gets flushed. Apparently no one else has encountered these troubles on Google search, did I miss any configuration piece? Any other suggestions please?

  • Finding the A Record for a Home Server [closed]

    - by Ryan Allred
    I have a hosted website that allows me to add subdomains and point them to different locations on the server. I also know that I can change the 'A Record' to point it to a different IP address. Now, here's the question, I have a home server that I need to access though this hosted website's domain name. How would I go about setting up the 'A Record' on the server to point to my home server. I'm usually pretty good about keyword searches but on this one, I'm pretty lost as to what to search for.

  • Running ADF Essentials in Tomcat

    - by Rodrigues, Raphael
    Oracle released a few days ago ADF Essentials, which is a free version of its Oracle ADF Framework. Oracle ADF Essentials can run on the Glassfish Application Server, well explained by Shay here  . Glassfish is also certified to run ADF Essentials Application. However, It could be possible to run ADF Essentials Applications in a Java EE Container. So, I’ll describe the steps to run the ADF Faces Rich Client demo application into a Tomcat 7. Before we start, you should download the files: • Apache Tomcat 7 : http://tomcat.apache.org/download-70.cgi • Oracle ADF Essentials 11.1.2.3 : http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html • Oracle ADF Faces Components Demo 11.1.2.3: http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html Steps: 1. Extract your tomcat 7. In my case, I choose D:\ apache-tomcat-7.0.29 2. Extract ADF Essentials zip file inside the %TOMCAT_HOME%\lib 3. Put the rcf-dvt-demo.war file inside the %TOMCAT_HOME%\webapps 4. Open the file %TOMCAT_HOME%\bin\catalina.bat (or .sh if you’re in linux environment) and add in the end of the line ‘set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%’ this -Xms1024m -Xmx1024m If you don’t do this, probably when you start you’ll see a OutOfMemory error. 5. Here is the little trick, tomcat does not come with jsf jar’s, so you have to put there. So, I went to the Oracle Jdeveloper 11.1.2 instalation and search for this files: • jsf-api.jar • jsf-impl.jar • glassfish.jstl_1.2.0.1.jar 6. You’re ready to start tomcat in %TOMCAT_HOME%\bin\startup.bat If everything is fine, you will be able to open your favourite browser and type http://localhost:8080/rcf-dvt-demo/faces/index.jspx

  • C#: Does an IDisposable in a Halted Iterator Dispose?

    - by James Michael Hare
    If that sounds confusing, let me give you an example. Let's say you expose a method to read a database of products, and instead of returning a List<Product> you return an IEnumerable<Product> in iterator form (yield return). This accomplishes several good things: The IDataReader is not passed out of the Data Access Layer which prevents abstraction leak and resource leak potentials. You don't need to construct a full List<Product> in memory (which could be very big) if you just want to forward iterate once. If you only want to consume up to a certain point in the list, you won't incur the database cost of looking up the other items. This could give us an example like: 1: // a sample data access object class to do standard CRUD operations. 2: public class ProductDao 3: { 4: private DbProviderFactory _factory = SqlClientFactory.Instance 5:  6: // a method that would retrieve all available products 7: public IEnumerable<Product> GetAvailableProducts() 8: { 9: // must create the connection 10: using (var con = _factory.CreateConnection()) 11: { 12: con.ConnectionString = _productsConnectionString; 13: con.Open(); 14:  15: // create the command 16: using (var cmd = _factory.CreateCommand()) 17: { 18: cmd.Connection = con; 19: cmd.CommandText = _getAllProductsStoredProc; 20: cmd.CommandType = CommandType.StoredProcedure; 21:  22: // get a reader and pass back all results 23: using (var reader = cmd.ExecuteReader()) 24: { 25: while(reader.Read()) 26: { 27: yield return new Product 28: { 29: Name = reader["product_name"].ToString(), 30: ... 31: }; 32: } 33: } 34: } 35: } 36: } 37: } The database details themselves are irrelevant. I will say, though, that I'm a big fan of using the System.Data.Common classes instead of your provider specific counterparts directly (SqlCommand, OracleCommand, etc). This lets you mock your data sources easily in unit testing and also allows you to swap out your provider in one line of code. In fact, one of the shared components I'm most proud of implementing was our group's DatabaseUtility library that simplifies all the database access above into one line of code in a thread-safe and provider-neutral way. I went with my own flavor instead of the EL due to the fact I didn't want to force internal company consumers to use the EL if they didn't want to, and it made it easy to allow them to mock their database for unit testing by providing a MockCommand, MockConnection, etc that followed the System.Data.Common model. One of these days I'll blog on that if anyone's interested. Regardless, you often have situations like the above where you are consuming and iterating through a resource that must be closed once you are finished iterating. For the reasons stated above, I didn't want to return IDataReader (that would force them to remember to Dispose it), and I didn't want to return List<Product> (that would force them to hold all products in memory) -- but the first time I wrote this, I was worried. What if you never consume the last item and exit the loop? Are the reader, command, and connection all disposed correctly? Of course, I was 99.999999% sure the creators of C# had already thought of this and taken care of it, but inspection in Reflector was difficult due to the nature of the state machines yield return generates, so I decided to try a quick example program to verify whether or not Dispose() will be called when an iterator is broken from outside the iterator itself -- i.e. before the iterator reports there are no more items. So I wrote a quick Sequencer class with a Dispose() method and an iterator for it. Yes, it is COMPLETELY contrived: 1: // A disposable sequence of int -- yes this is completely contrived... 2: internal class Sequencer : IDisposable 3: { 4: private int _i = 0; 5: private readonly object _mutex = new object(); 6:  7: // Constructs an int sequence. 8: public Sequencer(int start) 9: { 10: _i = start; 11: } 12:  13: // Gets the next integer 14: public int GetNext() 15: { 16: lock (_mutex) 17: { 18: return _i++; 19: } 20: } 21:  22: // Dispose the sequence of integers. 23: public void Dispose() 24: { 25: // force output immediately (flush the buffer) 26: Console.WriteLine("Disposed with last sequence number of {0}!", _i); 27: Console.Out.Flush(); 28: } 29: } And then I created a generator (infinite-loop iterator) that did the using block for auto-Disposal: 1: // simply defines an extension method off of an int to start a sequence 2: public static class SequencerExtensions 3: { 4: // generates an infinite sequence starting at the specified number 5: public static IEnumerable<int> GetSequence(this int starter) 6: { 7: // note the using here, will call Dispose() when block terminated. 8: using (var seq = new Sequencer(starter)) 9: { 10: // infinite loop on this generator, means must be bounded by caller! 11: while(true) 12: { 13: yield return seq.GetNext(); 14: } 15: } 16: } 17: } This is really the same conundrum as the database problem originally posed. Here we are using iteration (yield return) over a large collection (infinite sequence of integers). If we cut the sequence short by breaking iteration, will that using block exit and hence, Dispose be called? Well, let's see: 1: // The test program class 2: public class IteratorTest 3: { 4: // The main test method. 5: public static void Main() 6: { 7: Console.WriteLine("Going to consume 10 of infinite items"); 8: Console.Out.Flush(); 9:  10: foreach(var i in 0.GetSequence()) 11: { 12: // could use TakeWhile, but wanted to output right at break... 13: if(i >= 10) 14: { 15: Console.WriteLine("Breaking now!"); 16: Console.Out.Flush(); 17: break; 18: } 19:  20: Console.WriteLine(i); 21: Console.Out.Flush(); 22: } 23:  24: Console.WriteLine("Done with loop."); 25: Console.Out.Flush(); 26: } 27: } So, what do we see? Do we see the "Disposed" message from our dispose, or did the Dispose get skipped because from an "eyeball" perspective we should be locked in that infinite generator loop? Here's the results: 1: Going to consume 10 of infinite items 2: 0 3: 1 4: 2 5: 3 6: 4 7: 5 8: 6 9: 7 10: 8 11: 9 12: Breaking now! 13: Disposed with last sequence number of 11! 14: Done with loop. Yes indeed, when we break the loop, the state machine that C# generates for yield iterate exits the iteration through the using blocks and auto-disposes the IDisposable correctly. I must admit, though, the first time I wrote one, I began to wonder and that led to this test. If you've never seen iterators before (I wrote a previous entry here) the infinite loop may throw you, but you have to keep in mind it is not a linear piece of code, that every time you hit a "yield return" it cedes control back to the state machine generated for the iterator. And this state machine, I'm happy to say, is smart enough to clean up the using blocks correctly. I suspected those wily guys and gals at Microsoft engineered it well, and I wasn't disappointed. But, I've been bitten by assumptions before, so it's good to test and see. Yes, maybe you knew it would or figured it would, but isn't it nice to know? And as those campy 80s G.I. Joe cartoon public service reminders always taught us, "Knowing is half the battle...". Technorati Tags: C#,.NET

  • Ask the Readers: How Fast is Your Internet Connection?

    - by Mysticgeek
    The federal government recently announced a broadband initiative that calls for 260 million homes to have 100Mbps Internet connections by the year 2020. This got us wondering, how fast is your current Internet connection? Photo by roland When it comes to the speed of our Internet connection, we all want the maximum possible. The FCC recently announced their National Broadband Plan, which is an initiative to improve the Internet infrastructure in the United States and provide higher speeds to everyone. You’ve also undoubtedly heard the news about Google getting into the mix with their program to bring ultra high-speed fiber broadband to 50,000 users in select cities. While we wait for those programs to come into fruition, we thought it would be cool to check out what kinds of speeds you’re getting now. Test Your Internet Connection Speed There are several sites out there you can use to test your Internet speeds, but probably the best site is Speedtest.net. It’s easy to use, and allows you test download and upload speeds to and from various locations in the US and throughout the world. If you already know the speeds you’re getting leave a comment and let us know. If you use Speedtest.com, just keep in mind that our comment system won’t allow you to copy their result links, but you can simply tell us what you get in the results. We’re especially interested in the results of those of you who have Verizon FIOS or Comcast’s “Ultra” service. Leave a comment and join in the discussion!

  • MBSA: failed to create empty document

    - by Scott
    We just purchased a Windows-based VPS that I've been tasked to set up as a web server. It's running Windows 2003 Server Datacenter Edition. I downloaded the latest version of Microsoft Baseline Security Analyzer and installed it, but when I try to run it I'm given an error message "Failed to create empty document." A search on Google gave the suggestion to change the path of the TEMP and TMP environment variables, which I tried but it made no difference. I also saw suggestions that this problem is caused by MMC, but I was just in MMC setting up a user account. What am I missing?

  • SVN Export or Recursively Remove .SVN Folders

    - by Ben Griswold
    I shared this script with a coworker yesterday. It doesn’t do much; it recursively deletes .svn folders from a source tree.  It comes in handy if you want to share your codebase or you get in a terrible spot with SVN and you just want to start all over. Just blow away all svn artifacts and use your mulligan. It’s true. You can nearly get the same result using the SVN export command which copies your source sans the .svn folders to an alternate location.  The catch is an export only includes those files/folders which exist under version control.  If you want a clean copy of your source – versioned or not – export just might not do. The contents of the .cmd file include the following: for /f "tokens=* delims=" %%i in (’dir /s /b /a:d *.svn’) do ( rd /s /q "%%i" ) Just download and drop the unzipped “SVN Cleanup.cmd” file into the root of the project, execute and away you go.  If you search around enough, I know you can find similar scripts and approaches elsewhere, but I’m still uploading my script for completeness and future reference.

  • Fix Icon Display Problems by Rebuilding the Windows 7 Thumbnail Cache

    - by The Geek
    Have you ever been browsing through photos or videos on your PC, and noticed that the thumbnails weren’t showing up properly? Sometimes they get corrupted, and you can quickly rebuild them to fix the problem. Just for some background, let’s walk through what we’re talking about. Normally, when you’re browsing around your files, you’ll see thumbnails for pictures and videos that you are viewing. These thumbnails are all generated, and stored in a cache to make browsing files faster. But sometimes… the cache gets corrupted, and we need to rebuild them. Here’s an example of what happens when it goes out of whack… Rebuilding the Windows 7 Thumbnail Cache All you have to do is open up Disk Cleanup through the start menu search box (just type in disk cleanup to find it) Just make sure that Thumbnails is checked, and then click OK to run through the cleaning process.

  • Major Google not follow increase since introducing 301 to site

    - by jakob
    Recently we implemented Varnish in front of our web nodes so that the backend would get some rest from time to time. Since varnish is case sensitive and our app was not we implemented a 301 in varnish to redirect to small case. Example: You search for PlumBer StockHOLM you will get a 301 redirect to plumber stockholm and then plumber stockholm will be cached. This worked as a charm, but when checking the Google webmaster tools we suddenly got a crazy amount of Status - Not able to follow errors. As you can see in the image below: This of course stirred up some panic and I started to read up on the documentation once again. If I pressed on one of the links I got to the help section where i found this: Well this is strange, but as the day progressed more and more errors were thrown by Google. We took the decision to make varnish return 200 instead of the 301. Now when testing the links that appears in the Not able to follow section I get a 200 back. I have tested with Chrome, curl and lynx reader and everything looks ok but the amount of errors are still increasing. What is a little bit comforting is that the links that appears in the Not able to follow section are dated before the 200 change in varnish. Why do I get these errors and why do they keep increasing? Did google release something new on October 31? Maybe I do not understand the docs correctly?

  • Unable to remove broken Exchange 2003 installation (SBS 2003)

    - by Austin ''Danger'' Powers
    We have a non-functional Exchange 2003 installation on our SBS 2003 server that I am trying to uninstall. So far we have never used, and will never use, Exchange on this server- all we need is to remove it from the system (as it is installed on a partition which we want to merge with the main data partition to increase network storage capacity). Attempting to remove it using Add/Remove Programs produces the following error: When doing a search in ADUC to see which users still have a mailbox associated with them, it seems to only be the domain administrator account: As the Exchange installation is broken, it is not possible to run either System Manager or Exchange 5.5 Administrator to make mailbox changes. How can I forcibly remove a mailbox (which does not need to be salvaged or backed up), to allow the uninstall of Exchange to proceed? Any ideas would be appreciated!

  • SQL Server Windows Auth Login not working

    - by Mr Shoubs
    I've had someone set up a domain controller on windows 2008 on one server, and sql server 2008 on another. The domain seems to be working fine, I'm logged on as a domain user on both servers, nothing seems to be a problem there. However, when I try to add a domain user/group to SQL Server Security (e.g. clicking ok from the create login screen) it says it can't find it (even though I've used the search to find the correct account in the first place), when I try to logon (even though I haven't added it yet) it says something about the account being part of an untrusted domain instead of saying I don't have permission to log on. Anyone have any ideas on what is set up incorrectly?

  • How to Disable the Animations on the Windows 8 Start Screen

    - by Usman
    Who doesn’t love animations? They make everything look so cool. But in some cases, animations are a distraction, and the same is true for Windows 8′s start screen (the “Modern UI”). Fortunately, there’s a very simple way to disable all those animations. Keep reading to find out how it’s done. The animations are especially noticeable when you switch from the good ol’ peaceful desktop to the start screen by pressing the winkey. I don’t know about you, but it feels like I’m getting dizzy by watching all those crazy animations over and over again. People have found out ways to enhance the start screen animations, add delay to various elements and stuff like that. But we’re going the other way, disabling the animations completely. To do so, log in, and when the start screen appears, type “Computer” (it will pop up in the search results before you’ve even finished typing).

  • What's the difference between a wifi access point and station?

    - by Earlz
    I noticed that my (rooted) modem has some hidden modes for wifi. It has the default(and only setting without rooting) wireless access point, but it also has the settings repeater, ad-hoc, and station. What I'm really curious about is this station mode and how it differs from access point. I did a cursory search and didn't come up with any significant differences, other than that they are two distinct modes on many wireless chipsets. What is this station mode and how does it differ from access point?

  • Newly registered domain name still doesn't show up after 72 hours.

    - by BioGeek
    Seven days ago I ordered a domain name with a local (Belgian) domain name agent. I have already webspace at a shared host in the US, so I filled in their nameservers on the form. I immediately payed with my credit card. Three days ago I received an e-mail from the domain name agent, saying that my domain name was registered with the external nameservers I provided, and that the site would be visible within 24 hours. However, 72 hours after that mail I still can't see my domain name. A whois search shows indeed that my domain is registered on my name,but a ping to the domain returns unknown host and a traceroute gives the similar Name or service not known. What can have gone wrong, and which (Linux) commands can I use to find out. Or should I just be patient and will the domain name eventually be propagated?

  • Wire Framing WP7 Apps With Cacoo

    - by Tim Murphy
    While looking for a free alternative to Sketchflow I landed on the Cacoo web site.  Any developer who decides to use the free Visual Studio tools may find themselves doing the same search.  The base functionality of Cacoo is free although there are certain features that have fees attached to them such as extended stencils and templates. Cacoo doesn’t seem to have a template for WP7.  It does have templates for iOS and Android development so I started with the Android template and started modidfying it for WP7.  Funny thing is since Android has the same hardware vendors as Windows Phone the basic frame looks just right (I would swear I was looking at my Samsung Focus). Below is the start of a new mockup for the user group that I help run. I found that while Cacoo doesn’t have all the icons I need I am able to insert them from the Windows Phone Toolkit folder.  If I put them off to the side as you can see above.  I can simply copy and paste them into the appropriate place as needed.  Beyond that I have customized the main frame frame so I can have my base to work from.  In the future I intend to create this as a stencil and if it looks good enough I would consider making it public. My use of this product is still in it’s early phase, but it seems like a great way to start.  Maybe if you use this to get going you can earn enough from your resulting apps to pay for something with more bells and whistles in the future. del.icio.us Tags: WP7,Windows Phone 7 development,design,Cacoo,wire frame
