• latex page number position

  - by anton

  I am working on a long document in latex with documentclass book. I need the page number to always be in the upper right corner of each page, even if that page is the first page of a chapter (right now on 1st pages of chatpers, the page number is bottom-centered, on all other pages it's top-right). I control the position of the page number with fancyheader: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{} \chead{} \rhead{\thepage} \lfoot{} \cfoot{} \rfoot{} \renewcommand{\headrulewidth}{0pt} Also, I don;t know if the problem is realted but my chapters do not start from the top of the page. There is a white area, then comes chapter X, then a newline with the chapter line. What I also want is the chapter to start from the top of the page. The main question here is how I can get the page number to always appear in the upper right corner, I mention the thing with the chapter title position only in case that might be related. Thanks.

• How to obtain printed page count if no web-gui or driver-gui is available to show it

  - by Macgreggor at your service

  I am curious if windows print servers can keep a count of the printed pages sent to it? Can an individual PC (WinXP+)? Is there some secret command you can send it (with telnet, dos, etc)? I searched & couldn't find any questions similar to this here so lets keep this open-ended for future people who are curious. Is this more suited towards server fault? Maybe, but this is more about printers & local PC's have print servers now-a-days. Anyhow in my situation I have the following printers (yes old) I am curious on page-counts: HP Laserjet 1300 (using some kind of PC-card to LPT/Parallel adapter, then a network adapter on top of that [Netgear PS101 print server]) Canon Faxphone L80 Epson LX-300+

• 640 enterprise library caching threads - how?

  - by JohnW

  We have an application that is undergoing performance testing. Today, I decided to take a dump of w3wp & load it in windbg to see what is going on underneath the covers. Imagine my surprise when I ran !threads and saw that there are 640 background threads, almost all of which seem to say the following: OS Thread Id: 0x1c38 (651) Child-SP RetAddr Call Site 0000000023a9d290 000007ff002320e2 Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.WaitUntilInterrupted() 0000000023a9d2d0 000007ff00231f7e Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.Dequeue() 0000000023a9d330 000007fef727c978 Microsoft.Practices.EnterpriseLibrary.Caching.BackgroundScheduler.QueueReader() 0000000023a9d380 000007fef9001552 System.Threading.ExecutionContext.runTryCode(System.Object) 0000000023a9dc30 000007fef72f95fd System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object) 0000000023a9dc80 000007fef9001552 System.Threading.ThreadHelper.ThreadStart() If i had to give a guess, I'm thinkign that one of these threads are getting spawned for each run of our app - we have 2 app servers, 20 concurrent users, and ran the test approximately 30 times...it's in the neighborhood. Is this 'expected behavior', or perhaps have we implemented something improperly? The test ran hours ago, so i would have expected any timeouts to have occurred already.

• How to handle BL cache for multiple web applications?

  - by Eran Betzalel

  I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application). I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.

• When should I use a UserControl instead of a Page?

  - by dthrasher

  I notice that many of the WPF MVVM frameworks seem to avoid using the NavigationWindow and Page controls in favor of composing pages using nested UserControls. The NavigationWindow and Page provide easy ways to enable back and forward navigation in the journal as well as providing an easy way to pass data among pages. Most MVVM frameworks I've seen re-implement these features in various ways. Is there a specific reason to avoid using NavigationWindow and Page?

• How to stop page refresh when hit enter button from rich:inputNumberSpinner field?

  - by eswaramoorthy-nec

  Hi, I use rich:inputNumberSpinner tag. The problem is : I set cursor focus to inside of rich:inputNumberSpinner field, then i hit the enter button from my keyboard, that time page will be automatically refresh. But i don't need page refresh when i hit the enter button from my keyboard. The code : spinnerTagTest.jsp <%@page contentType="text/html" pageEncoding="UTF-8"%> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://richfaces.org/a4j" prefix="a4j" %> <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <f:view> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Spinner Tag Test</title> </head> <body> <h:form id="SpinnerForm"> <rich:panel id="SpinnerPanel"> <h:outputText value="Input Spinner Tag : "/> <rich:inputNumberSpinner id="spinnerField" value="" maxValue="23" inputSize="2"/> </rich:panel> </h:form> </body> I also use rich:hotKey for that inputNumberSpinner field.

• Access container page of a component in .net based CT

  - by Huston Lopes

  We are developing a .net based CT based on Broker query Mechanism (filter): ComponentPresentationAssembler cpAssembler = new ComponentPresentationAssembler(Page ID,Page object); In order to pass the page ID, I need to get the access of page on which the component is present. How can I access the page from package? Since this a CT, a component object would be available in page and not a page object. Tried the following piece of code, but without success: string pageURI = _package.GetValue("Page.ID"); Page objPage = (Page)_engine.GetSession().GetObject(pageURI); This is not working as there is no page object. What are the alternatives so that we can access the parent page of component from CT?

• How do I apply a ViewModel to the UserControl inside of a Page?

  - by Mike

  Doing something like this: <DataTemplate DataType="{x:Type vm:AllCustomersViewModel}"> <vw:AllCustomersView /> </DataTemplate> works in a ResourceDictionary for when I want to apply a ViewModel to a UserControl as root, but how do I the same thing when I have a UserControl inside of a Page? Would I create a ResourceDictionary for all my Pages then at the top of each Page do something like: <Page.Resources> <ResourceDictionary Source="../MainWindowResources.xaml"/> </Page.Resources> Any help is greatly appreciated, thanks!

• Caching issues with TDBadgedCell

  - by Wolfgang Schreurs

  This post is closely related to my previous post: http://stackoverflow.com/questions/2201256/tdbadgedcell-keeps-caching-the-badgenumber The "badge" from TDBadgedCell keeps caching the numbers. A very simple example is shown here: - (UITableViewCell *)tableView:(UITableView *)_tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; TDBadgedCell *cell = (TDBadgedCell *)[_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[TDBadgedCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; } [cell setBadgeColor:[UIColor blackColor]]; [cell setBadgeNumber:[indexPath row]]; [[cell textLabel] setText:[NSString stringWithFormat:%@"%d", [indexPath row]]]; return cell; } Anyone has any clue why this happens? The textLabel and detailTextLabel don't cache the data. Any additonal info would be welcome as well, as I seem to have a lot of issues with the caching of graphics in UITableViewCells. Any best practices or other useful information would be most welcome.

• Jquery / PHP - pre-loading next page before navigating to it.

  - by Tim

  Hey all Using jQuery, is there a way to prevent going to the next page until the animation has finished AND the next page has completely loaded (including images)? The code below works but it is a bit clunky. You can see what I am trying to achieve here: http://bit.ly/aOeYgE The first three or so pages work. But when you click to go to the homepage a few times (after it's cached) you will see that it jumps, and the animation isn't very smooth. As you can see with the code below, the height is immediately set to 0, then when the page has loaded the height is set to 500px. When users navigate to a new page, the height should go back to 0, the next page content should load, and then upon loading the new window, the first bit of code will run again to set the width back to 500px. $(".content-center").css({"height": "0px"}); $(window).load(function() { if($('.content-center').is(':not(:animated)')) { $('.content-center').animate({height: "500px"}, 450); } }); $("a").click(function(event){ $(".content-center").animate({height: "0px"}, 500); if($('.content-center').is(':not(:animated)')) { navigate($(this).attr('href')); event.preventDefault(); } }); If anyone has any suggestions or alternative ideas to this code then it would be hugely appreciated. Many thanks Tim

• Is there a way to detect when a WSS default.aspx page is updated?

  - by Alan

  That is detect when the user makes web part changes and selects to exit editing the page. I want to be able to capture a page event, then create a SharePoint task to instruct a user to translate that page to another language (note that MOSS and variations is not an option because the client wants to use the free version of SharePoint). So the customer wants essentially the same WSS site in multiple languages.

• Database triggers / referential integrity and in-memory caching

  - by Ran Biron

  Do you see database triggers / referential integrity rules being used in a way that changes actual data in the database (changing row w in table x causes a change in row y in table z)? If yes, How does this tie-in with the increasing popularity of in-memory caching (memcache and friends)? After all, these actions occur inside the database but the caching system must be aware of them in order to reflect to correct state (or at least invalidate the possibly changed state). I find it hard to believe that callbacks are implemented for such cases. Does anyone have real-world experience with such a setup / real-world experience with considering such a setup and abandoning it (which way did you go? if caching, how do you enforce integrity?)

• static images aren't caching with php-generated page

  - by scootklein

  Our website was just converted to being generated by mod_rewrite and php scripts. Images aren't caching in browsers when they seemingly should be. All images follow format: <img src="/images/header.png" /> I must avoid the script completely caching because the PHP parser needs to handle each page dynamically on each request; however, the download overhead of the large images is cumbersome on every single page load. I would ideally provide headers for "Cache-Control: no-cache, must-revalidate" and "Expires: some_date_in_the_past" to force revalidation of the PHP script. Why isn't the browser caching static images with consistent href values across all pages?

• Performance-optimizing Oracle 10g on a server that is also a Tomcat JSP app server?

  - by PKHunter

  I have inherited a simple RedHat 5 - 64bit platform. It has SCSI disks on RAID1, with 16GB of RAM. Double Core CPU. Oracle 10g, Release 2. This would be a decent platform for running the DB only, perhaps, but the same server in an "A-A mode" clustering (very simple) also runs Tomcat and there are several Java servlets running on this. Sadly there is no caching platform etc. We only use an external CDN for some html caching. I am personally more familiar with web environments on the LAMPP platform (apache, php, mysql, postgresql). PROBLEM: Because the server has both Tomcat JSP/Java and Oracle 10g running on the same server, with no caching, I have some issues of the server going down. Often, sadly. QUESTION: What are my options in terms of improving performance of all these different apps? Connection Pooling? Example, in Postgresql world we have PgBouncer, which really helps things. Does Oracle have something similar? Or is there a famous Java-based external pooler that people use in production environments? (I'm not familiar with Java) Any "SQL cache" as in the MySQL and Postgresql world? Any other kind of application cache, as "APC" or "eAccelarator" in the PHP world? The "OSCache" stuff from the Java world (JSP thingie I found on Google: http://onjava.com/pub/a/onjava/2005/01/05/jspcache.html?page=2) ... What else? Sorry if this is a noob question. I have googled and googled, but problem is I don't know what to google for, other than the broad general concepts above. So if not full answers, I would even appreciate basic pointers and I am happy to JFGI myself. Thanks!

• How to display a page in my browser with python code that is run locally on my computer with "GAE" S

  - by brilliant

  When I run this code on my computer with the help of "Google App Engine SDK", it displays (in my browser) the HTML code of the Google home page: from google.appengine.api import urlfetch url = "http://www.google.com/" result = urlfetch.fetch(url) print result.content How can I make it display the page itself? I mean I want to see that page in my browser the way it would normally be seen by any user of the internet.

• What conditions cause a web browser to display the "Page Expired" message?

  - by RichardHowells

  I assumed that sending a page out with an expiry (a la)... Response.Cache.SetExpires(System.DateTime.Now.AddSeconds(5)); Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetValidUntilExpires(true); ...would mean that if the user hit the back button they would see the expired page. It does not seem to work that way. I found that using the back button would simply show the old (IMO expired) page. In fact in experimenting with different combinations of caching/not caching and expiry times I NEVER managed to get the "Page Expired" message out of the browser. What conditions provoke that message? Server Environment ASP .Net. I've only tested in IE8 - I'm assuming that other browsers are consistent here.

• test php disabled caching

  - by user1691389

  My site had a problem in that certain browsers (especially opera and gecko) were "over-caching" (caching far too much for my taste). I've just added the following PHP snippet to hopefully disable caching in all browsers: <?php header("Expires: Tue, 01 Jan 2000 00:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); ?> Question: How would you test this out, to make sure it actually works?

• Consolidating multiple domain names

  - by Mike

  I have a client that has three separately hosted copies of their website, each on a separate domain name. The websites are all essentially the same, bar a few discrepancies caused by badly managed updates in the past. I will soon be launching a completely new website for them, at which point, all three domain names are to resolve to the same web server. One domain name will become the default domain name that they refer to in all their literature, and the other two will simply be used as catch-alls for old links, bookmarks, and so on. I would like to know what people consider the best route to achieve this. My plan so far is: Get the new site up and running on the new webserver. Change the relevant A record of the default domain name to point to the new webserver. a) Keep the existing hosting accounts in operation. Create a list of 301 redirects from old page names on the old site to new page names on the new site. or b) Configure CNAME records for the non-default domain names, each pointing to the new webserver. Create a list of 301 redirects on the new site that redirect from old page names to new page names. If my understanding is correct, 3a will help to maintain whatever search engine rankings the sites already have (I know it's not going to be perfect), while at the same time informing search engines that the old domain names are no longer in use. What's a good approach to take here?

• Stop squid caching 302 and 307 with deny_info

  - by 0xception

  TLDR: 302, 307 and Error pages are being cached. Need to force a refresh of the content. Long version: I've setup a very minimal squid instance running on a gateway which shouldn't not cache ANYTHING but needs to be solely used as a domain based web filter. I'm using another application which redirects un-authenticated users to the proxy which then uses the deny_info option redirects any non-whitelisted request to the login page. After the user has authenticated the firewall rule gets placed so they no longer get sent to the proxy. The problem is that when a user hits a website (xkcd.com) they are unauthenticated so they get redirected via the firewall: iptables -A unknown-user -t nat -p tcp --dport 80 -j REDIRECT --to-port 39135 to the proxy at this point squid redirects the user to the login page using a 302 (i've also tried 307, and i've also make sure the headers are set to no-cache and/or no-store for Cache-Control and Pragma). Then when the user logs into the system they get firewall rule which no longer directs them to the squid proxy. But if they go to xkcd.com again they will have the original redirection page cached and will once again get the login page. Any idea how to force these redirects to NOT be cached by the browser? Perhaps this is a problem w/ the browsers and not squid, but not sure how to get around it. Full squid config below. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 192.168.182.0/23 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl https port 443 acl http port 80 acl CONNECT method CONNECT # # Disable Cache # cache deny all via off negative_ttl 0 seconds refresh_all_ims on #error_default_language en # Allow manager access only from localhost http_access allow manager localhost http_access deny manager # Deny access to anything other then http http_access deny !http # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !https visible_hostname gate.ovatn.net # Disable memory pooling memory_pools off # Never use neigh cache objects for cgi-bin scripts hierarchy_stoplist cgi-bin ? # # URL rewrite Test Settings # #acl whitelist dstdomain "/etc/squid/domains-pre.lst" #url_rewrite_program /usr/lib/squid/redirector #url_rewrite_access allow !whitelist #url_rewrite_children 5 startup=0 idle=1 concurrency=0 #http_access allow all # # Deny Info Error Test # acl whitelist dstdomain "/etc/squid/domains-pre.lst" deny_info http://login.domain.com/ whitelist #deny_info ERR_ACCESS_DENIED whitelist http_access deny !whitelist http_access allow whitelist http_port 39135 transparent ## Debug Values access_log /var/log/squid/access-pre.log cache_log /var/log/squid/cache-pre.log # Production Values #access_log /dev/null #cache_log /dev/null # Set PID file pid_filename /var/run/gatekeeper-pre.pid SOLUTION: I believe I might have found a solution to this. After days and days trying to figure it out, only through a random stumble I found client_persistent_connections off server_persistent_connections off This did the trick. So it wasn't so much cache as it was a single persistent connection messing things up. W000T!

• How to enable caching on Apache2 (using as load balancer)

  - by csl

  I'm using Apache 2 as my load balancer (mod_jk). I've 2 Tomcat servers behind my load balancer. What I'm trying to do is to enable caching of my static pages in my load balancer using mod_cache but nothing seems to be working. I confirmed this by creating a simple JSP page that prints out current date time and I always get the latest date time (indicating that the JSP page is not cached). OS: Ubuntu
