• How do I uninstall a ruby version installed via source?

  - by Aaron McIver

  I installed a version (1.9.3-p194) of ruby via source using make install and realized this may have been the wrong route to take. Upon doing this, I realized this was a mistake and I should be using a solution such as rvm to address my ruby versions within the OS. I looked to see if an uninstall existed to be ran in conjunction with make and it didn't. I then proceeded to install rvm and add the aforementioned version in to my list of managed rubies within rvm which is not listed as ext-ruby-1.9.3-p194. rvm rubies ext-ruby-1.9.3-p194 [ x86_64 ] =* ruby-1.9.3-p194 [ x86_64 ] # => - current # =* - current && default # * - default** When I perform an rvm remove, it simply removes it from the rubies list however it still exists within /usr/local/bin. I am not concerned with the system install ruby version residing in /usr/bin as I understand that is tied to the OS and should simply be ignored. How can I safely uninstall/remove the aforementioned version and all the places in which it was installed, short of looking at the install script?

• Folder cannot be deleted

  - by Aaron

  I am using Windows XP Home Edition. When I try to delete a folder I have named cygwin. When I try to delete it or any file or folder within it, there is a long pause, and then an error pops up, saying: Cannot delete Cygwin: Access is denied. Make sure the disk is not full or read-write protected and that the file is not currently in use. I have tried deleting the folder and the files it contains with FileAssassin, and unlocking it with LockHunter. Neither report any errors unless I try to have them delete the file or folder, then I get an error message saying Access Denied. I have rebooted into Safe Mode to change the ownership, but I get Access Denied when I click OK or Apply. How can I delete this folder?

• Ruby installed on Ubuntu 10.10 slow on one machine but not other

  - by Aaron Jensen

  I have a machine that was provisioned several months ago. RVM was used to install ruby 1.9.3-p125 as well as 1.9.3-p125-perf. When I compared raw ruby performance to another identical machine the older machine smoked them. For example: ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 3.790000 0.000000 3.790000 ( 3.800895) each 2.410000 0.000000 2.410000 ( 2.420860) any 3.960000 0.000000 3.960000 ( 3.972099) include 1.440000 0.000000 1.440000 ( 1.442862) ------------------------------------ total: 11.600000sec vs ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 10.740000 0.000000 10.740000 ( 10.769366) each 6.080000 0.010000 6.090000 ( 6.106323) any 10.600000 0.000000 10.600000 ( 10.641606) include 4.160000 0.000000 4.160000 ( 4.171530) ------------------------------------ total: 31.590000sec I attempted to reinstall 1.9.3-p125 with rvm on the fast machine and that ruby is now slow. It's as if something changed in RVM, or I installed some package that made compiled versions of ruby perform significantly worse. I know this is a tough question to answer, but what things should I look into in order to track down why the performance has suffered so much? edit I just attempted to install with ruby-build and the version installed was fast. Something rvm is doing to build it in my environment is slow.

• Alt+click-drag window resizing on a Mac? (Similar to X-Windows)

  - by Aaron F.

  Is there a way I can get this behavior on Mac OS? alt + right-click-drag will resize the window, relative to where you've clicked within the window and the window's center alt + left-click-drag will move the window, regardless of where you've clicked within the window. There's a Windows port of this behavior as well: http://www.codeproject.com/KB/DLL/wm.aspx

• Enterprise Redirection Services?

  - by Aaron Alton

  This is probably a case of "if I new what it was called, I could google it in 5 minutes" - but I don't know what it's called. It's probably best to explain the requirement using an example. We have a number of services (vpn, owa, etc) which we host from one of our datacenters. We have a number of datacenters, and we technically have the infrastructure already in place to support these services at a number of our datacenters. To provide access to these "services", I would create an external DNS entry (ex. VPN.MyCompany.com Gateway IP for one of my DCs), and clients will connect to it via the DNS entry. Since I have multiple datacenters that can support this service, I could theoretically offer a "highly available, geographically dispersed" solution if I could point this DNS entry to some sort of third party who offers highly available "redirection" services. If my primary site goes down, I could just make a change via some management console and configure the redirector to point to a different DC. Of course, it would be fairly straightforward to set this sort of thing up on one of our servers, but that would kinda defeat the purpose of a highly available third party. Is anyone familiar with a service like this? I'm thinking something like DynDNS, but with Enterprise availability guarantees.

• How to find the process(es) which are hogging the machine

  - by Aaron Digulla

  Scenario: All of a sudden, my computer feels sluggish. Mouse moves but windows take ages to open, etc. uptime says the load is 7.69 and raising. What is the fastest way to find out which process(es) are the cause of the load? Now, "top" and similar tools isn't the answer because they either show CPU or memory usage but not both at the same time. What I need is the single command which I might be able to type as it happens - something that will figure out any of System is trying to swap 8GB of RAM to disk because process X ... or process X seeks all over the disk or process X uses 400% CPU" So what I'm looking for is iostat, htop/atop and similar tools run into one with an output like this: 1235 cp - Disk trashing 87 chrome - Uses 2&nbsp;GB of RAM 137 nfs_bench - Uses 95% of the network bandwidth I don't want a tool that gives me some numbers which I can analyze but a tool that tells me exactly which process causes the current load. Assume that the user in front of the keyboard barely knows how to write "process", but the user is quickly overwhelmed when it comes to "resident size", "virtual memory" or "process life cycle". My argument goes like this: A user notices a problem. There can be thousands of reasons ... well, almost :-) The user wants to know the source of the problem. The current solutions give me lots of numbers, and I need to know what these numbers mean. What I'm looking for is a meta tool. 99% of the data is irrelevant to the problem. So what the tool should do is look for processes which hog some resource and list only those along with "this process needs a lot of CPU, this produces many IRQs, this process allocates a lot of RAM (and it's still growing)". This will be a relatively short list. It will be much more simple for someone new to this to locate the culprit from this list than from the output of, say, htop which gives me about 5000 numbers but requires me to fold multi-threaded processes myself (I have 50 lines which say VIRT 2750M but only 16 GB of RAM - the machine ought to swap itself to death but of course, this is a misinterpretation of the data that can happen quickly).

• SQL Server 2005 Replication Subscription Expiring Warning

  - by Aaron

  This week one of my replication subscriptions expired because I wasn't getting any alerts saying that there was a login error (I've fixed those alerts and the error). What I'd like now is, in the case that this happens again, to be able to send an alert saying that a subscription is about to expire (ie, it will expire in 1 or 2 days). I have an alert set up for when a subscription expires, but this is after the fact. I've looked through sys.messages for any text that has "Expir" in it, but I haven't found an appropriate error code yet. Would anyone be able to point me in the right direction? Thanks.

• Morris.JS X-Axis Label Height

  - by Aaron

  I have a chart generated with Morris.JS but the labels on the x-axis are to long and being cut off due to the limited height of the area showing the labels. The code below would render a graph that only shows the partial label for "COUNTY PARK ROAD ELEM.". How can I adjust the height of the label area to show the entire text? The code is as follow if ($('#IP1').length){ Morris.Bar({ element: 'IP1', data: [ {x: 'COUNTY PARK ROAD ELEM.', yIndex: 376.92} ], xkey: 'x', ykeys: ['yIndex'], labels: ['Index Points'], ymax: 500, barRatio: 0.2, xLabelAngle: 45, hideHover: 'auto' }); }

• C# WebBrowser Control System.AccessViolationException

• Intermittent PolicyException: Execution permission cannot be acquired.

  We are intermittently seeing the following exception shortly after an App Pool recycle in an ASP.NET application: System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

We're running on ASP.NET 3.5 on Windows Server 2008. This seems to happen in batches affecting some but not all of sites on the same App Pool. We have a large number of sites all running the same code. Once a site has failed to load a DLL it throws up a Yellow Screen of Death until the next App Pool recycle. We haven't been able to reproduce this behavior and the sites seem to work fine for days or weeks at a time (and many App Pool recycles) before failing. Has anybody else seen similar behavior? Update: We've tried reproducing the failure by setting up a few hundred sites and writing a script to hit them repeatedly while recycling the App Pool once every couple of minutes and were unable to accomplish much other than loading down the server's CPU for a few days straight. We then tried messing (locking one of the DLLs, changing the file permissions) with the copies of the DLLs that ASP.NET makes and managed to reproduce similar behavior but not the same exception. Does anybody have any ideas on how to adjust the security policy to get it to throw a System.Security.Policy.PolicyException: Execution permission cannot be acquired. when loading a specific DLL?

• Resizing QT's QTextEdit to Match Text Height: maximumViewportSize()

  - by Aaron

  I am trying to use a QTextEdit widget inside of a form containing several QT widgets. The form itself sits inside a QScrollArea that is the central widget for a window. My intent is that any necessary scrolling will take place in the main QScrollArea (rather than inside any widgets), and any widgets inside will automatically resize their height to hold their contents. I have tried to implement the automatic resizing of height with a QTextEdit, but have run into an odd issue. I created a sub-class of QTextEdit and reimplemented sizeHint() like this: QSize OperationEditor::sizeHint() const { QSize sizehint = QTextBrowser::sizeHint(); sizehint.setHeight(this->fitted_height); return sizehint; } this-fitted_height is kept up-to-date via this slot that is wired to the QTextEdit's "contentsChanged()" signal: void OperationEditor::fitHeightToDocument() { this->document()->setTextWidth(this->viewport()->width()); QSize document_size(this->document()->size().toSize()); this->fitted_height = document_size.height(); this->updateGeometry(); } The size policy of the QTextEdit sub-class is: this->setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::Preferred); I took this approach after reading this post. Here is my problem: As the QTextEdit gradually resizes to fill the window, it stops getting larger and starts scrolling within the QTextEdit, no matter what height is returned from sizeHint(). If I initially have sizeHint() return some large constant number, then the QTextEdit is very big and is contained nicely within the outer QScrollArea, as one would expect. However, if sizeHint gradually adjusts the size of the QTextEdit rather than just making it really big to start, then it tops out when it fills the current window and starts scrolling instead of growing. I have traced this problem to be that, no matter what my sizeHint() returns, it will never resize the QTextEdit larger than the value returned from maximumViewportSize(), which is inherited from QAbstractScrollArea. Note that this is not the same number as viewport()-maximumSize(). I am unable to figure out how to set that value. Looking at QT's source code, maximumViewportSize() is returning "the size of the viewport as if the scroll bars had no valid scrolling range." This value is basically computed as the current size of the widget minus (2 * frameWidth + margins) plus any scrollbar widths/heights. This does not make a lot of sense to me, and it's not clear to me why that number would be used anywhere in a way that supercede's the sub-class's sizeHint() implementation. Also, it does seem odd that the single "frameWidth" integer is used in computing both the width and the height. Can anyone please shed some light on this? I suspect that my poor understanding of QT's layout engine is to blame here.

• javascript - multiple dependent/cascading/chained select boxes on same form

  - by Aaron

  I'm populating select box options via jquery and json but I'm not sure how to address multiple instances of the same chained select boxes within my form. Because the select boxes are only rendered when needed some records will have ten sets of chained select boxes and others will only need one. How does one generate unique selects to support the auto population of secondary select options? Here's the code I'm using, and I thank you in advance for any insight you may provide. <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function populateACD() { $.getJSON('/acd/acd2json.php', {acdSelect:$('#acdSelect').val()}, function(data) { var select = $('#acd2'); var options = select.attr('options'); $('option', select).remove(); $.each(data, function(index, array) { options[options.length] = new Option(array['ACD2']); }); }); } $(document).ready(function() { populateACD(); $('#acdSelect').change(function() { populateACD(); }); }); </script> <?php require_once('connectvars.php'); $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); $squery = "SELECT ACD1ID, ACD1 from ACD1"; $sdata = mysqli_query($dbc, $squery); // Loop through the array of ACD1s, placing them into an option of a select echo '<select name="acdSelect" id="acdSelect">'; while ($row = mysqli_fetch_array($sdata)) { echo "<option value=" . $row['ACD1ID'] .

• script running very slow in IE with Jquery quickflip plug-in

  - by Aaron Carlino

  I have a jQuery plugin running on my site that is executing very, very slowly in IE7/8 to the point that it throws a slow script warning to the user. It doesn't happen in any other browser, and I can't figure out what might be going on. If you go to this page: http://dev.xeetic.org/projects You'll see that there are 16 results on each page, and each one has a "flip" behavior attached, using the jQuery plugin "quickflip." Attaching this behavior is very slow in IE. If I reduce the result set to 8 or 4 per page, it's faster, but still very bogged down. I have contacted the author of the script with no success. I am willing to pay for a solution, if I'm allowed to offer such a thing on this site.

• How to refactor large projects in visual studio

  - by Aaron

  I always run into a problem where my projects in Visual Studio (2008) become huge monstrosities and everything is generally thrown into a Web Application project. I know from checking out some open source stuff that they tend to have multiple projects within a solution, each with their own responsibilities. Does anyone have any advice for how to refactor this out? What should be in a separate project vs. part of the web project? Can you point me to any reference materials on the subject, or is it just something you become accustomed to with time?

• jQuery Cycle plugin IE6/7 issues

  - by Aaron Moodie

  I've implemented a slideshow using the Cycle plugin, which is working in all browsers except IE6&7, where the images just show up in a list, and the #page_copy div is not hiding. I've been going through the code all day without any luck, and not exactly sure how or what I should be looking for. What would be the best way to go about debugging this issue? I know that the #page_copy div is hiding when I remove the rest of the code, and I've tried the reverse (which had no result) <script type="text/javascript" charset="utf-8"> jQuery.fn.fadeToggle = function(speed, easing, callback) { return this.animate({opacity: 'toggle'}, speed, easing, callback); }; $(document).ready(function() { $('#page_copy').hide(); $('a#info_close_button').click(function() { $('#page_copy').fadeOut(200); return false; }); $('a#info_button').click(function() { $('#page_copy').fadeToggle(200); return false; }); }); $(window).load(function() { // vertically center single image var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } }); // wait until images have loaded before starting cycle $(window).load(function() { // front image rotator $('#images').cycle({ fx: 'fade', speed: 300, next: '.next', prev: '.prev', containerResize: 0, timeout: 0, delay: -2000, before: onBefore }); }); // hide all but the first image when page loads $(document).ready(function() { $('#images img:gt(0)').hide(); }); // callback fired when each slide transition begins function onBefore(curr,next,opts) { var $slide = $(next); var w = $slide.width(); var h = $slide.height(); $slide.css({ marginTop: (620 - h) / 2, marginLeft: (650 - w) / 2 }); }; </script>

• JavaBeans and DSLs

  - by Aaron Digulla

  It's 2009 and we still all hold on the JavaBeans despite all their flaws, mostly because of the tooling support which we wrote in our own blood. But now we have method chaining and internal DSLs and some pressure to replace or extend JavaBeans with DSL classes. Has anyone an implementation that implements PropertyDescriptor for a DSL (where the getters and setter use the exact same name as the property) and a way to hook that into the Java RT so I don't need to create them all by myself?

• Twitter Bootstrap 3 top nav dropdown covered by subnav bar

• Arrrg! MovieClip object refuses to moved in any rational way in as3?

  - by Aaron H.

  I have a MovieClip object, which is exported for actionscript (AS3) in an .swc file. When I place an instance of the clip on the stage without any modifications, it appears in the upper left corner, about half off stage (i.e. only the lower right quadrant of the object is visible). I understand that this is because the clip has a registration point which is not the upper left corner. If you call getBounds() on the movieclip you can get the bounds of the clip (presumably from the "point" that it's aligned on) which looks something like (left: -303, top: -100, right: 303, bottom: 100), you can subtract the left and top values from the clip x and y: clip.x -= bounds.left; clip.y -= bounds.top; This seems to properly align the clip fully on stage with the top left of the clip squarely in the corner of the stage. But! Following that logic doesn't seem to work when aligning it on the center of the stage! clip.x = (stage.stageWidth / 2); etc... This creates the crazy parallel universe where the clip is now down in the lower right corner of the stage. The only clue I have is that looking at: clip.transform.matrix and clip.transform.concatenatedMatrix matrix has a tx value of 748 (half of stage height) ty value of 426 (Half of stage height) concatenatedMatrix has a tx value of 1699.5 and ty value of 967.75 That's also obviously where the movieclip is getting positioned, but why? Where is this additional translation coming from?
