  • Did You Know? I'm doing 3 more online seminars with SSWUG!

    - by Kalen Delaney
    As I told you in April , I recorded two more seminars with Stephen Wynkoop, on aspects of Query Processing. The first one will be broadcast on June 30 and the second on August 27. In between, we'll broadcast my Index Internals seminar, on July 23. Workshops can be replayed for up to a week after the broadcast, and you can even buy a DVD of the workshop.

  • Optimizing data downloaded via 'link' media queries and asynchronous loading

    - by adam-asdf
    I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?

  • IE8 HTTPs Download Issue

    - by Jon Egerton
    I have a problem with a system I develop related to IE8 downloading over SSL (ie on sites using https://...) and is described on this MS kb article: http://support.microsoft.com/kb/323308 We use the HTTPCacheability.NoCache option as the data being downloaded is sensitive, and is downloaded from a secured site. I don't want that data to be cached on any of the proxies etc that the response passes through back to the client. The article describing the issue details a fix to the client side registry changing a BypassSSLNoCacheCheck setting. I don't want to loosen the system security just for IE8, as the system works fine on anything more upto date. Getting all the clients to apply the hotfix is difficult at best, and impossible at worst. We need to support IE8 in the system, at least for now. So: 1: Does the detailed hotfix have any implications for the security at the browser end in IE8 - does it mean the file will be cached? (in a place other than where the user saves the file). 2: Is there some way I can get these files downloadable with a change at the server end that doesn't break the security side of things?

  • How to specify expiration of cacheable resources?

    - by Richard
    I'm trying to speed up a wordpress site -- this site: http://richardclunan.net I'm following the observations here: http://gtmetrix.com/reports/richardclunan.net/9ps7Zc0j The first item says: "The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:" How do I specify expirations for those things? (I'm not very technically-minded, and likely won't know relevant terminology -- really appreciate baby-steps explanation if possible :)

  • Geek City: sp_cacheobjects for SQL Server 2012

    - by Kalen Delaney
    In a post about 4 1/2 years ago , I gave you my version of a replacement for the old pre-2005 pseudotable syscacheobjects . I called it sp_cacheobjects and created it as a view in the master database. With the sp _ prefix, the view can be accessed from any database. When testing this on SQL Server 2012, I noticed that I almost always got a lot more rows back than I was expecting. Even when I added a WHERE clause to limit the database to only the database I was working in, I STILL got way to many...(read more)

  • Non-dynamic CMS [closed]

    - by user20457
    Some of the web sites I visit every day (news, sports, etc..), although the content changes very often (several times per day), the URLs always have .html extension, what makes me thing that the content has been generated once, and then published as a static page, rather than generated in every call, or even cached in memory. For example, the fictitious site "mysports.com" have a "futbol.html" page, and then yesterday Messi gets injured and they have another thing to put in that page, then I presume they post the new item in their CMS system, and automatically a publishing action is triggered aftewards that recreates "futbol.html" in a CDN with the new item and probably discard the oldest one. Then the ETag changes and clients will get the new page if they try to access it. (the site is fictitious but this is what I believe happened yesterday in the sports site I read) This would fit in the CQRS approach, and I presume they have a huge performance. I know lots of CMS (WP, Drupal, BlogEngine.net, DNN, etc...), but I have never seen any able of doing this, or at least, I was not aware this feautre. How are called those distributed CMS? Which are the most well known? Cheers.

  • Cloudflare displaying cached CSS in-line?

    - by esqew
    I recently enabled CloudFlare on my domain, and when I make HTML statements like this: <link href="css/main.css" rel="stylesheet" /> The CSS gets displayed in-line, like this: <style>body{padding-top:40px}span.light{font-weight:lighter!important}span.title{font-size:60px;line-height:1;letter-spacing:-1px;color:inherit}</style> When I update the file via FTP, the changes are not reflected, which leads me to believe that this is a caching issue. Is this due to CloudFlare? If so, how do I disable the behavior? EDIT I also came to the conclusion that caching is behind the behavior after being able to see changes in the page after re-naming the CSS file.

  • IIS and content caching

    - by JayC
    I'm a web developer and administer of a Windows 2008R2 Could Instance with IIS 7. I recently made an update to our website, but when I revisited the website, the website was being viewed with old stylings. I did a refresh (shift + reload button in Firefox) and of course the website displayed as it should. I didn't worry about it, until my client had the same issue in Safari. So, my question, in general, is, how do I prevent this from happening again, and yet still afford some caching of our site? I noticed we did not have content expiration set up on our webserver sites, so I've set that up, but did I really need to? I've also looked at Etags, and, honestly, it's hard for me to know whether or not I should use them or not. One comment I read somewhere there isn't really any issue with Etags scenarios in IIS (even in webfarms)... but, I dunno. Anybody have any suggestions, links, info? Thanks.

  • NHibernate L2 Cache - fluent nHibernate configuration

    - by AWC
    I've managed to configure the L2 cache for Get\Load in FHN, but it's not working for queries configured using the ICriteria interface - it doesn't cache the results from these queries. Does anyone know why? The configurations are as follows: ICriteria: return unitOfWork .CurrentSession .CreateCriteria(typeof(Country)) .SetCacheable(true); Entity Mapping: public sealed class CountryMap : ClassMap<Country>, IMap { public CountryMap() { Table("Countries"); Not.LazyLoad(); Cache.ReadWrite().IncludeAll(); Id(x => x.Id); Map(x => x.TwoLetter); Map(x => x.ThreeLetter); Map(x => x.Name); } } And the session factory configuration for the database property: return () => MsSqlConfiguration.MsSql2005 .ConnectionString(BuildConnectionString()) .ShowSql() .Cache(c => c.UseQueryCache() .QueryCacheFactory<StandardQueryCacheFactory>() .ProviderClass(configuration.RepositoryCacheType) .UseMinimalPuts()) .FormatSql() .UseReflectionOptimizer(); Cheers AWC

  • How to cache L2E entity without attach/detach?

    - by Eran Betzalel
    The following code will select a key/value table in the DB and will save the result to the cache: using (var db = new TestEntities()) { if(Cache["locName_" + inventoryLocationName] != null) return Cache["locName_" + inventoryLocationName]; var location = db.InventoryLocationsSet.FirstOrDefault( i => i.InventoryLocationName.Equals( inventoryLocationName, StringComparison.CurrentCultureIgnoreCase)); db.Detach(location); // ???? Cache["locName_" + inventoryLocationName] = location; return location; } But it doesn't work well when I'm trying to use the cached object. Of course, the problem is the different ObjectContext, so I use Attach/Detach and then the problem solves but with a codding horror price: db.Attach(locationFromCache); // ???? try { // Use location as foreign key db.SaveChanges(); } finally { db.Detach(locationFromCache); // ???? } So, how can I use cached objects without using attach/detach methods? What happens if more than one user will have to use this cached object? Should I put the whole thing in a CriticalSection?!

  • IE: Undocumented "cache" attribute defined for input elements?

    - by aefxx
    Hi everybody. I've stumpled upon a strange behavior in IE(6/7/8) that drives me nuts. Given the following markup: <input type="text" value="foo" class="bar" cache="yes" send="no" /> Please note that the cache attribute is set to yes. However IE somehow manages to change the attributes value to cache="cache" when rendering the DOM. So, I wonder, is there an undocumented feature that I'm not aware of? I've googled about an hour now but couldn't find any info on this (not even on MSDN). NOTE I'm aware that adding custom attributes is non-standard compliant and that boolean attributes should be noted as attribute="attribute. Nevertheless I have to cope with these as they were introduced long before I joined the team. These custom attributes are used in conjunction with javascript to provide a more user friendly approach to form handling (and it works out quite well with Firefox/Safari/Opera/Chrome). I know that I could simply convert these custom attributes to x-data attributes that will be introduced with HTML5 but that would take me several hours of extra work - sigh. Hope, I made myself clear. Thanks in advance.

  • What does 'postMessage()' do when called on an object tag?

    - by Stephano
    I was recently searching for a way to call the print function on a PDF I was displaying in adobe air. I solved this problem with a little help from this fellow, and by calling postMessage on my PDF like so: //this is the HTML I use to view my PDF <object id="PDFObj" data="test.pdf" type="application/pdf"/> ... //this actionscript lives in my air app var pdfObj:Object = htmlLoader.window.document.getElementById("PDFObj"); pdfObj.postMessage([message]); I've tried this in JavaScript as well, just to be sure it wasn't adobe sneaking in and helping me out... var obj = document.getElementById("PDFObj"); obj.postMessage([message]); Works well in JavaScript and in ActionScript. I looked up what the MDC had to say about postMessage, but all I found was window.postMessage. Now, the code works like a charm, and postMessage magically sends my message to my PDF's embedded JavaScript. However, I'm still not sure how I'm doing this. Any ideas?

  • Trouble with object injection in Spring.Net

    - by Abdel Olakara
    Hi all, I have a issue with my Spring.Net configuration where its not injecting an object. I have a CommService to which an object named GeneralEmail is injected to. Here is the configuration: <!-- GeneralMail Object --> <object id="GeneralMailObject" type="CommUtil.Email.GeneralEmail, CommUtil"> <constructor-arg name="host" value="xxxxx.com"/> <constructor-arg name="port" value="25"/> <constructor-arg name="user" value="[email protected]"/> <constructor-arg name="password" value="xxxxx"/> <constructor-arg name="template" value="xxxxx"/> </object> <!-- Communication Service --> <object id="CommServiceObject" type="TApp.Code.Services.CommService, TApp"> <property name="emailService" ref="GeneralMailObject" /> </object> The communication service object is again injected to many other aspx pages & service. In one scenario, I need to call the commnucation service from an static WebMethod. I try doing: CommService cso = new CommService(); But when i try to get the emailService object, its null! why didn't the spring inject the GeneralMail object into my cso object? What am I doing wrong and how do I access the object from spring container. Thanks in advance for the suggestions and solutions. Reagrds, Abdel Olakara

  • For each <item> in CheckedListBox. <item> returns as Object and not as Control

    - by Tivie
    Hello there. I have a CheckedListBox previously populated. I want to loop with a "for each / next" through all items in the CheckedListBox and do a lot of "stuff" with each iteration element of the checkedlistbox. example code: For Each item In CheckedListBox1.Items If item.Checked = True Then 'do stuff like item.BackColor = Color.Blue Else 'do other stuff item.BackColor = Color.Brown End If Next the problem is that is an 'Object' type and not a 'Control' type. If I force the iteration var As CheckBox, it throws an InvalidCastException saying that type 'System.String' can't be associated with type 'System.Windows.Forms.CheckBox' I know I can easily work around using for i=0 to CheckedListBox.Items.Count - 1 but I want to use a for each /next loop since I have a lot of code in that loop (and With can't be used) and always poiting directly to the object is something I wish to avoid and I really need the code to be as simple as possible. I actually spent one afternoon looking for this but couldn't find any answer. If someone could be kind enough to enlight me in this, it would be extremely appreciated. Best regards

  • Rails runner command not saving to cache

    - by mark
    Hi I'm having a bit of a problem with a cron task generated by rails whenever plugin that should store remote data in the rails cache for display. What I have is this: schedule.rb set :path, '/var/www/apps/tuexplore/current' every 1.hour do runner "Weather.cache_remote", :environment => :production end calls this model class Weather def self.cache_remote Rails.cache.write('weather_data', Net::HTTP.get_response(URI.parse(WEATHER_URL)).body) end end Calling whenever returns this PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/deploy/.gem/ruby/1.8/bin 0 * * * * /var/www/apps/tuexplore/current/script/runner -e production "Weather.cache_remote" This doesn't work. Calling the weather model method from a controller works fine, but I need to schedule it hourly. The cron task causes a "Cache write: weather_data" entry to appear in the production log but data isn't stored nor output into the page. Additional information, I can log into production console and run Weather.cache_remote, then read the data from the rails cache. I'd be really appreciative if someone could point out the error of my ways. If further explanation is needed please ask. Thanks in advance for any pointers.

  • Require reasonably random results from an SQL SELECT query within a Joomla article (Cache enabled)

    - by Shrinivas
    Setup: Joomla website on LAMP stack I have a MySQL table containing some records, these are queried by a simple SELECT on the Joomla article, as pasted below. This specific Joomla website has Caching turned on in Joomla's Global Configuration. I need to randomize the order in which I display the resultset, each time the page is loaded. Regular php/mysql would offer me two approaches for this: 1. use 'order by RAND()' or any of a number of methods to allow a SELECT query to return reasonably random results. 2. once php gets the result from the SELECT into an array, shuffle the array to get a reasonably random order of array items. However, as this Joomla instance has Caching turned ON in its Global Configuration, either of the above approaches fails. The first time I load the page the order is randomized, however any further reloads do not cause the order to change, as the page is delivered from cache. The instant the Cache is disabled, both approaches (shuffle/order by rand) work perfectly. What am I missing? How do I override the Global Cache for this specific article? A very simple requirement, that is met by both php and mysql reasonably well, is blocked by the Joomla Cache that I cannot turn off. The php that returns results from the database. <pre> $db = JFactory::getDBO(); $select = "SELECT id FROM jos_mytable;"; //order by RAND() $db->setQuery($select); echo $db->getQuery(); //Show me the Query! $rows = $db->loadObjectList(); //shuffle($rows); foreach($rows as $row) { echo "$row->id"; }

  • Why junit ComparisonFailure is not used by assertEquals(Object, Object) ?

    - by Philippe Blayo
    In Junit 4, do you see any drawback to throw a ComparisonFailure instead of an AssertionError when assertEquals(Object, Object) fails ? assertEquals(Object, Object) throws a ComparisonFailure if both expected and actual are String an AssertionError if either is not a String @Test(expected=ComparisonFailure.class ) public void twoString() { assertEquals("a String", "another String"); } @Test(expected=AssertionError.class ) public void oneString() { assertEquals("a String", new Object()); } The two reasons why I ask the question: ComparisonFailure provide far more readable way to spot the differences in dialog box of eclipse or Intellij IDEA (FEST-Assert throws this exception) Junit 4 already use String.valueOf(Object) to build message "expected ... but was ..." (format method invoqued by Assert.assertEquals(message, Object, Object) in junit-4.8.2): static String format(String message, Object expected, Object actual) { ... String expectedString= String.valueOf(expected); String actualString= String.valueOf(actual); if (expectedString.equals(actualString)) return formatted + "expected: " + formatClassAndValue(expected, expectedString) +" but was: " + formatClassAndValue(actual, actualString); else return formatted +"expected:<"+ expectedString +"> but was:<"+ actualString +">"; Isn't it possible in assertEquals(message, Object, Object) to replace fail(format(message, expected, actual)); by throw new ComparisonFailure(message, formatClassAndValue(expectedObject, expectedString), formatClassAndValue(actualObject, actualString)); Do you see any compatibility issue with other tool, any algorithmic problem with that... ?

  • Refresh page using cache

    - by cbh
    I am trying to refresh a page, but WANT to use the cache and can't figure out how to do this. There are two situations: If I click in the URL bar and hit enter (or visit the page from somewhere else) it reloads the page/images from the cache. GREAT! If I click on the refresh button or use Javascript to refresh the page it grabs all the images again and takes forever. NOT GREAT! I've tried: top.location.reload(false); and top.location.reload(true); (I'm sending this from in an iFrame) and neither used the cache. I'm avoiding using location so it doesn't end up in the browser history twice. Question: How do I reload the page using the cached images? Is there a different javascript function or is this a mod_expires issue? Thanks for any help in advance! EDIT: (info from chrome: developer tools) When navigating to the page I get "From Cache" for all images When refreshing page I get "304 - Not Modified" for all images (and it takes the time to download each)

  • ruby rails loop causes server freeze

    - by Darkerstar
    Hi all: I am working on a Ruby on Rails project on Windows. I have Ruby 1.86 and Rails 2.35 installed. Everything is fine until I tried to implement a comet process. I have the following code written to respond to a long poll javascript request. But everytime this function is called, it will hang the whole rails server, no second request can get in, until the timeout. (I know there is juggernaut, but I like to implement one myself first :) Is this due to my server setup? The project will be deployed on a linux server with Ngix and Passenger setup, will it suffer the same problem? def comet_hook timeout(5) do while true do key = 'station_' + station_id.to_s + '_message_lastwrite' if Rails.cache.exist?(key) @cache_time = DateTime.parse(Rails.cache.read(key)) if @cache_time > hook_start @messages = @station.messages_posted_after(hook_start) hook_start = @cache_time break end end end ... end Also with Rails memory store cache, I keep getting "cannot modify frozen object" error, so the above script only worked for me when I switched to File cache. :(

  • How to implement Session timeout in Web Server Side?

    - by Morgan Cheng
    I beheld a web framework implementing in-memory session in this way. The session object is added to Cache with timeout. When the time is out, the session is removed from Cache automatically. To protect race condition, each request should acquire lock on given session object to proceed. Each request will "touch" the session in Cache to refresh the timeout. Everything looks fine, until this scenario is discovered. Say, one operation takes a long time, longer than timeout. Another request comes and wait on session lock which is currently hold by the long-time request. Finally, the long-time request is over, it releases the lock. But, since it already takes longer time than timeout, the session object is already removed from Cache. This is obvious because the only request holding the lock doesn't have a chance to "touch" the session object in cache. The second request gets the lock but cannot retrieve the expired Session object. Oops... To fix this issue, the second request has to re-create the Session object. But, this is just like digging a buried dead body from tomb and try to bring it back to life. It causes buggy code. I'm wondering what's the best way to implement timeout in session to handle such scenario. I know that current platform must have good session mechanism. I just want to know the under-the-hood how.
