  • Caching all files in varnish

    - by csgwro
    I want my varnish servers to cache all files. At backend there is lighttpd hosting only static files, and there is an md5 in the url in case of file change, ex. /gfx/Bird.b6e0bc2d6cbb7dfe1a52bc45dd2b05c4.swf). However my hit ratio is very poorly (about 0.18) My config: sub vcl_recv { set req.backend=default; ### passing health to backend if (req.url ~ "^/health.html$") { return (pass); } remove req.http.If-None-Match; remove req.http.cookie; remove req.http.authenticate; if (req.request == "GET") { return (lookup); } } sub vcl_fetch { ### do not cache wrong codes if (beresp.status == 404 || beresp.status >= 500) { set beresp.ttl = 0s; } remove beresp.http.Etag; remove beresp.http.Last-Modified; } sub vcl_deliver { set resp.http.expires = "Thu, 31 Dec 2037 23:55:55 GMT"; } I have made an performance tuning: DAEMON_OPTS="${DAEMON_OPTS} -p thread_pool_min=200 -p thread_pool_max=4000 -p thread_pool_add_delay=2 -p session_linger=100" The main url which is missed is... /health.html. Is that forward to backend correctly configured? Disabling health checking hit ratio increases to 0.45. Now mostly "/crossdomain.xml" is missed (from many domains, as it is wildcard). How can I avoid that? Should I carry on other headers like User-Agent or Accept-Encoding? I thing that default hashing mechanism is using url + host/IP. Compression is used at the backend. What else can improve performance?

  • Displaying a list of objects with Views - Drupal

    - by RadiantHex
    Hi folks, I'll briefly explain what I'm trying to do: I need to sort a set of content-types within a paginated page. Also I need to add filtering to the page, for example each content-type should have a set of tags and the filter needs to filter through these tags. This is a basic mockup of what this page consists of: I'm finding it quite hard figuring out the best way to do it, and if this can be done. Help would be very much appreciated!!

  • advanced python autovivification

    - by Zhang18
    This question is about implementing the full PERL autovivification in python. I know similary questions were asked before and so far the best answre is http://stackoverflow.com/questions/635483/what-is-the-best-way-to-implement-nested-dictionaries-in-python/652284#652284. However, I'm looking to do this: a['x']['y'].append('z') without declaring a['x']['y'] = [] first, or rather, not declaring a['x'] = {} either. I know dict and list classes sorta don't mix so this is hard, but I'm interested in seeing if someone has an ingenius solution probably involving creating an inherited class from dict but defined a new append method on it? I also know this might throw off some python purists who will ask me to stick with Perl. But even just for a challenge, I'd like to see something. thx!

  • How to measure a canvas that has auto height and width

    - by Wymmeroo
    Hi Folks, I'm a beginner in silverlight so i hope i can get an answer that brings me some more light in the measure process of silverlight. I found an interessting flap out control from silverlight slide control and now I try to use it in my project. So that the slide out is working proper, I have to place the user control on a canvas. The user control then uses for itself the height of its content. I just wanna change that behavior so that the height is set to the available space from the parent canvas. You see the uxBorder where the height is set. How can I measure the actual height and set it to the border? I tried it with Height={Binding ElementName=notificationCanvas, Path=ActualHeight} but this dependency property has no callback, so the actualHeight is never set. What I want to achieve is a usercontrol like the tweetboard per example on Jesse Liberty's blog Sorry for my English writing, I hope you understand my question. <Canvas x:Name="notificationCanvas" Background="Red"> <SlideEffectEx:SimpleSlideControl GripWidth="20" GripTitle="Task" GripHeight="100"> <Border x:Name="uxBorder" BorderThickness="2" CornerRadius="5" BorderBrush="DarkGray" Background="DarkGray" Padding="5" Width="300" Height="700" > <StackPanel> <TextBlock Text="Tasks"></TextBlock> <Button x:Name="btn1" Margin="5" Content="{Binding ElementName=MainBorder, Path=Height}"></Button> <Button x:Name="btn2" Margin="5" Content="Second Button"></Button> <Button x:Name="btn3" Margin="5" Content="Third Button"></Button> <Button x:Name="btn1_Copy" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy1" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy2" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy3" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy4" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy5" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy6" Margin="5" Content="First Button"/> </StackPanel> </Border> </SlideEffectEx:SimpleSlideControl>

  • Are "proxy properties" good style?

    - by erlando
    I have a class with a string property that's actually several strings joined with a separator. I'm wondering if it is good form to have a proxy property like this: public string ActualProperty { get { return actualProperty; } set { actualProperty = value; } } public string[] IndividualStrings { get { return ActualProperty.Split(.....); } set { // join strings from array in propval .... ; ActualProperty = propval; } } Is there any risks I have overlooked?

  • Having two IP Routes/Gateways of last Resort on an HP Switch

    - by SteadH
    We have an HP Layer 3 Switch that is doing IP routing between vlans. The general set up is that the switch has an IP address on each VLAN and IP routing is enabled. On our servers VLAN, we have a firewall that has a connection to the outside world. To set a IP route on the HP router, we use IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.1 where 192.168.2.1 is the address of our firewall, and the zeros essentially mean to route all traffic that the switch doesn't know what to do with out the firewall as a gateway. We're in the middle of an ISP and firewall change. I set up the new firewall and ran the IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.254 (the address of the new firewall). Things started working nicely. When I reviewed the configuration of the switch though, I noticed that it did not replace the previous ip route command, but just added another route. Now, I know how to remove the old firewall route (no ip route 0.0.0.0 0.0.0.0 192.168.2.1), but what is the effect of having these two 0.0.0.0 routes? Is it switch implosion? Will a server just respond back over the route it receives the request from? I've read elsewhere that having two default gateways is an impossibility by definition, but I'm curious about this situation that our switch allowed. Thanks!

  • bloated jquery xml requests

    - by Tim Joyce
    Hi, I was wondering if anyone had an alternative to this. $(xml).find("a").each(function(){ $(this).find('b').each(function(){ $(this).find('c').each(function(){ $(this).find('d1').each(function(){ sectionValidation.RegisterTerms.setRegisterTermsArray(this); }); $(this).find('d2').each(function(){ sectionValidation.RegisterTerms.checkValidVariations(this, val); }); }); }); }); It seems really bloated and there has to be a more elegant approach to getting nested xml data. Thank you

  • Strange compilation error - GAS3 generated class

    I am pretty new to GraniteDS..So far I have been able to successfully configure it to work with my remote java services as well as generate the equivalent AS3 files from my POJO's. But I am getting this strange error while building one of the classes using GAS3 [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[77,29] Syntax error: expecting identifier before use. public function set use(value:String):void { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[77,52] Syntax error: expecting leftparen before leftbrace. public function set use(value:String):void { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[77,52] Syntax error: expecting identifier before leftbrace. public function set use(value:String):void { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[77,52] Syntax error: expecting rightparen before leftbrace. public function set use(value:String):void { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[80,29] Syntax error: expecting identifier before use. public function get use():String { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[80,42] Syntax error: expecting leftparen before leftbrace. public function get use():String { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[80,42] Syntax error: expecting identifier before leftbrace. public function get use():String { [ERROR] C:\TestGDS_All\TestGDS-flex-remoteobjects\target\generated-sources\com\mycompany\TestGDS\masterdata\model\TankGradesMlBas e.as:[80,42] Syntax error: expecting rightparen before leftbrace. public function get use():String { The java class appears like this @Entity` @Table(name = "mmd_tank_grades_ml") @SuppressWarnings("serial") public class TankGradesMl implements Serializable { .... private String use; @Basic @Column(name = "USE", length = 45) public String getUse() { return use; } public void setUse(String use) { this.use = use; } What am I doing wrong?

  • Adding business logic to a domain class using a getter style method name

    - by Richard Paul
    I'm attempting to add a method to a grails domain class, e.g. class Item { String name String getReversedName() { name.reverse() } } When I attempt to load the application using grails console I get the following error: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory':Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property reversedName in class Item ... 18 more It looks like Hibernate is interpreting getReversedName() as a getter for a property, however in this case it is a derived field and hence should not be persisted. Obviously in my actual code the business logic I'm exposing is more complex but it isn't relevant to this question. I want to be able to call item.reversedName in my code/gsps. How can I provide property (getter) access to a method in a Grails domain class without Grails attempting to map it with Hibernate?

  • mysqli_stmt_bind_param SQL Injection

    - by profitphp
    Is there still an injection risk when using prepared statements and mysqli_stmt_bind_param? For example: $malicious_input = 'bob"; drop table users'; mysqli_stmt_bind_param($stmt, 's', $malicious_input); Behind the scenes does mysqli_stmt_bind_param pass this query string to mysql: SET @username = "bob"; drop table users"; Or does it perform the SET command through the API, or use some type of protection to keep this from happening?

  • Multiple Settings for One Monitor

    - by Lynda
    I have my monitor set to the way I like it, it shows colors accurately and not overly bright (white doesn't blind me). However I edit photos for the web and this is great for my screen but I have noticed when looking at other screens my photos will at times looked washed out and not a good presentation. If I manually change my monitor settings to be brighter (and a few other tweaks) I can replicate the look of other monitors close enough to help prevent washed out/blown out photos. Here is the issue, I need to be able to change settings between the two fairly easily. To manually set my monitor for one then back to the other can be time consuming and a pain to set right every time. I would like to be able to preset certain settings (in software) that I can quickly switch between by pressing hotkeys or clicking shortcut on my desktop. I have an AMD video card and have attempted to use the AMD VISION Engine Control Center to add presets then tweak the settings for each. However when I switch between the presets the settings are the same. How do I build presets using the VISION Engine Control Center that actually works (maybe I misunderstand what it is saving?) or is there a way to do this in Windows 7 or free software that actually works decently for this purpose?

  • prevent race condition without using locks C++

    - by Hristo
    How do I prevent a race condition with locking or using mutexes/semaphors in C++? I'm dealing with a nested for loop in which I will be setting a value in an array: for (int i = 0; i < m; ++i) for (int j = 0; j < n; ++j) for (int k = 0; k < o; ++k) array[k] += foo(...); More or less, I want to deal with this so that I can ensure different threads running at the same time don't write to array[k] at the same time. Any suggestions on how to approach this? Thanks, Hristo

  • File paths with XSLT includes

    - by Andrew Parisi
    Hi again everyone. I'm working on a website with a large number of pages, and each one has this in it: <xsl:include href="team-menu.xsl" /> This xsl file is stored in the root directory. Essentially including my "team menu" on each page. My problem is when I include this on nested pages, e.g. "/teammembers/smith.xsl", the links in the menu are broken because they refer to pages that aren't in the same directory as the page i'm viewing. This is probably really easy, but I just don't know how to fix it. Is there a way to tell the XSL the root directory and/or set some sort of global directory? Thanks for your help!

  • How do i handle a heavy page?

    - by Ulhas Tuscano
    I have been asked to design & develop a page in asp.net which contains 7 tabs.Each table contains 2 Editable gridview & clicking on gridview cell should open a popup & that popup will open a new popup ( I would say nested popup). even when i switch from one tab to another. It should hold the griddata & whenever user will finish all the operations he/she will click on save button which will save all the data contained in the tabs. The page is really too too too heavy. It will definitely take a long time to load as it contains gridview operations , popup related jobs, tab data & tab switching. I am finding the best way i can achieve this with an acceptable speed of operation. Any suggestions or help would be greatly appreciated.
