• Android page Curl animation

  - by Meymann

  Hi... Two questions: Is there a simple way to do the Curl page flipping animation? A Curl animation is animation of pages flipping, including the page above rolling and the shadows over the lower page. What is the recommended way to do a "gallery" that displays two pages at a time (just like a book)? Is it: Letting the adapter display a linear layout of two images at a time? (it won't let me show a page flipping over the other like a book) Using two pages, placing somehow one near the other, and then when it's time to animate -move the next two pages over? What is the better way that would enable displaying the left page flipping over the right page? Thanks Meymann

• How to analyze 'dbcc memorystatus' result in SQL Server 2008

• Use RegEx in Java to extract parameters in between parentheses

  - by lars_bx

  I'm writing a utility to extract the names of header files from JSPs. I have no problem reading the JSPs line by line and finding the lines I need. I am having a problem extracting the specific text needed using regex. After looking at many similar questions I'm hitting a brick wall. An example of the String I'll be matching from within is: <jsp:include page="<%=Pages.getString(\"MY_HEADER\")%>" flush="true"></jsp:include> All I need is MY_HEADER for this example. Any time I have this tag: <%=Pages.getString I need what comes between this: <%=Pages.getString(\" and this: )%> Here is what I have currently (which is not working, I might add) : String currentLine; while ((currentLine = fileReader.readLine()) != null) { Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\]*)"); Matcher matcher = pattern.matcher(currentLine); while(matcher.find()) { System.out.println(matcher.group(1).toString()); }} I need to be able to use the Java RegEx API and regex to extract those header names. Any help on this issue is greatly appreciated. Thanks! EDIT: Resolved this issue, thankfully. The tricky part was, after being given the right regex, it had to be taken into account that the String I was feeding to the regex was always going to have two " / " characters ( (/"MY_HEADER"/) ) that needed to be escaped in the pattern. Here is what worked (thanks to the help ;-)): Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\\"]*)");

• Sitewide 301 Redirect with a subset of different redirects

  - by Mike E.

  I am trying to make a sitewide 301 redirect for a site with around 400 pages but also have a subset of about 10 individual pages that don't follow the sitewide redirect and should point somewhere else. Any ideas how to format such redirect rules so the sitewide redirect doesnt conflict with the subset pages redirect? I am starting with the sitewide redirect rule as: Options +FollowSymLinks RewriteEngine on RewriteRule (.*) http://www.name.com/$1 [R=301,L]

• .htaccess allow from hostname?

  - by Mikey B

  Ubuntu 9.10 Apache2 Hi Guys, Long story short, I need to restrict access to a certain part of my web site based on a dynamic IP source address that changes every now and then. Historically, I've just added the following to htaccess... order deny,allow deny from all # allow my dynamic IP address allow from <dynamic ip> But the problem is that I'll have to manually make this change every time the IP changes. Ideally I'd like to specify a hostname instead... something like: order deny,allow deny from all # allow my host allow from hostname.whatever.local That doesn't seemed to have worked though. I get an error 403 - access forbidden. Does .htaccess not support hostnames?

• Django - How to do CSFR on public pages? Or, better yet, how should it be used period?

  - by orokusaki

  After reading this: http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#how-to-use-it I came to the conclusion that it is not valid to use this except for when you trust the person who is using the page which enlists it. Is this correct? I guess I don't really understand when it's safe to use this because of this statement: This should not be done for POST forms that target external URLs, since that would cause the CSRF token to be leaked, leading to a vulnerability. The reason it's confusing is that to me an "external URL" would be on that isn't part of my domain (ie, I own www.example.com and put a form that posts to www.spamfoo.com. This obviously can't be the case since people wouldn't use Django for generating forms that post to other people's websites, but how could it be true that you can't use CSRF protection on public forms (like a login form)?

• ASP.NET MVC OutputCache with POST Controller Actions

  - by Maxim Z.

  I'm fairly new to using the OutputCache attribute in ASP.NET MVC. Static Pages I've enabled it on static pages on my site with code such as the following: [OutputCache(Duration = 7200, VaryByParam = "None")] public class HomeController : Controller { public ActionResult Index() { //... If I understand correctly, I made the whole controller cache for 7200 seconds (2 hours). Dynamic Pages However, how does it work with dynamic pages? By dynamic, I mean where the user has to submit a form. As an example, I have a page with an email form. Here's what that code looks like: public class ContactController : Controller { // // GET: /Contact/ public ActionResult Index() { return RedirectToAction("SubmitEmail"); } public ActionResult SubmitEmail() { //In view for CAPTCHA: <%= Html.GenerateCaptcha() %> return View(); } [CaptchaValidator] [AcceptVerbs(HttpVerbs.Post)] public ActionResult SubmitEmail(FormCollection formValues, bool captchaValid) { //Validate form fields, send email if everything's good... if (isError) { return View(); } else { return RedirectToAction("Index", "Home"); } } public void SendEmail(string title, string name, string email, string message) { //Send an email... } } What would happen if I applied OutputCache to the whole controller here? Would the HTTP POST form submission work? Also, my form has a CAPTCHA; would that change anything in the equation? In other words, what's the best way to approach caching with dynamic pages? Thanks in advance.

• Easy way to observe user activity - how improve my database structure.

  - by Thomas

  Welcome, I need some advise to improve perfomence my web application. In the begin I had this structure of database: USER -id (Primary Key) -name -password -email .... PROFILE -user Primary Key, Foreign Key (USER) -birthday -region -photoFile ... PAGES -id (Primary Key) -user Foreign Key(USER) -page -date COMMENTS -id (Primary Key) -user Foreign Key(USER) -page Foreign Key(PAGE) -comment -date FAVOURITES_PAGES -id (Primary Key) -user Foreign Key(USER) -favourite_page Foreign Key(PAGE) -date but now one of the most important page of website is observatory, when everyone can observe activity others users. So I need select all pages, comments and favourites pages some users and display it in one list, sorted by date. For better perfomance (I think) I changed my structure to this: table USER and PROFILE without changes ACTIVITY (additional table- have common fields: user,date) -id (Primary Key) -user Foreign Key(USER) -date -page Foreign Key(PAGE) -comment Foreign Key(COMMENTS) -favourite_page Foreign Key(FAVOURITES_PAGES) PAGES -id (Primary Key) -page COMMENTS -id (Primary Key) -page Foreign Key(PAGE) -comment FAVOURITES_PAGES -id (Primary Key) -favourite_page Foreign Key(PAGE) So now it is very easy get sorted records from all tables. But I have no only foreign key to PAGES, COMMENTS and FAVOURITES_PAGES in ACTIVITY table - there is about ten Foreign Key fields and in one record only one have value, others have None: ACTIVITY id user date page comment ... 1 2 2010-02-23 None 1 2 1 2010-02-21 1 None .... It is corect solution. When I display about 40 records in one page (pagination) I must wait about one secound, but database is almost emty (a few users and about 100 records in others tables). It is depends on amount records per page - I have checked it, but why it takes too long time, becouse of relationships? The website is built in Python/Django. Any advices/opinion?

• Windows 2003 DNS updates from ISC DHCP server

  - by wolfgangsz

  We have a very mixed network, with most clients being Debian Lenny, the rest Windows XP/Vista/7. The network itself is split into two segments (for technical reasons) called "corporate" and "engineering". On the "corporate" side all clients get their IP addresses from a Windows DHCP server and the dynamic updates into the Windows DNS work just fine. On the "engineering" side, clients get their IP addresses from a linux machine running the standard ISC DHCP server. Although this server is configured to do dynamic DNS updates, they actually don't work. Anybody got any advice on how to fix this? Please note: dynamic updates from the clients directly into the DNS would work, but are not an option for us. So this is strictly on how make this work from an ISC DHCP server to a Windows DNS server.

• Relay thru external SMTP server on Exchange 2010

  - by MadBoy

  My client has dynamic IP on which he hosts Exchange 2010 with POP3 Connector running and gathering emails from his current hosting. Until he gets static IP he wants to send emails out. This will work most of the time but some servers won't accept such email sent by Exchange (from dynamic ip due to multiple reasons) so I would like to make a relay thru external SMTP server which hosts current mailboxes. Normally SMTP server could be set up to allow relay thru it but this would require static IP to be allowed on that server so it would know which IP is allowed to relay thru it. Or is there a way to setup relay in Exchange 2010 so it can use dynamic IP and kinda authenticates with user/password itself on the hosted server?

• Htaccess rewrite rule .aspx to .php

  - by Markus Ossi

  Background: I have a website that has been built with ASP.NET 2.0 and is on Windows hosting. I now have to rewrite my site in PHP and move it into Linux hosting. I have a lot of incoming links to my site from around the web that point directly into the old .aspx-pages. The site itself is very simple, one dynamic page and five static ones. I saved the static .aspx pages as .php-pages and rewrote the dynamic page in PHP. The dynamic page is called City.aspx and I have written it in PHP and it is now called City.php. On my old Windows hosting, I used ASP.NET's URL mapping for friendly URL. For example, incoming URL request for Laajakaista/Ypaja.aspx was mapped into City.aspx?CityID=981. My goal: To redirect all human visitors and search engines looking for the old .aspx pages into the new .php pages. I am thinking that the easiest way to redirect visitors into new pages will be by making a redirect, where all requests for .aspx-files will be redirected into .php filetypes. So, if someone asks for MYSITE/City.aspx?CityID=5, they will be taken into MYSITE/City.php?CityID=5 instead. However, I am having a lot of trouble getting this to work. So far this is what I have found: rewriterule ^([.]+)\.aspx$ http://www.example.com/$1.php [R=301,L] However, I think this can not handle the parameters after the filetype and I am also not quite sure what to put on front. To make things a bit more complicated, at my previous site I used friendly URL's so that I had a huge mapping file with mappings like this: <add url="~/Laajakaista/Ypaja.aspx" mappedUrl="~/City.aspx?CityID=981" /> <add url="~/Laajakaista/Aetsa.aspx" mappedUrl="~/City.aspx?CityID=988" /> <add url="~/Laajakaista/Ahtari.aspx" mappedUrl="~/City.aspx?CityID=989" /> <add url="~/Laajakaista/Aanekoski.aspx" mappedUrl="~/City.aspx?CityID=992" /> I tried to make a simple redirect like this: Redirect 301 Laajakaista/Aanekoski.aspx City.php?CityID=992 but was not able to get it to work. I ended up with an internal server error and a 50k .htaccess-file... Any help is greatly appreciated.

• "Mem Usage" higher than "VM Size" in WinXP Task Manager

  - by Frederick

  In my Windows XP Task Manager, some processes display a higher value in the Mem Usage column than the VMSize. My Firefox instance, for example shows 111544 K as mem usage and 100576 K as VMSize. According to the help file of Task Manager Mem Usage is the working set of the process and VMSize is the committed memory in the Virtual address space. My question is, if the number of committed pages for a process is A and the number of pages in physical memory for the same process is B, shouldn't it always be B = A? Isn't the number of pages in physical memory per process a subset of the committed pages? Or is this something to do with sharing of memory among processes? Please explain. (Perhaps my definition of 'Working Set' is off the mark). Thanks.

• How to Manage project in this scenario

  - by vijay.shad

  Hi All, I am working on a web application which has got good amount of static or pre-login pages. These pages can have some simple forms as well where we would like to capture the visitor's details. Post login, I have got my main application. I am confused about the development and deployment architecture of my application. Post login part of my application has a release cycle of 1-2 months while pre-login pages are to be updated on a weekly basis. It is difficult to make a release of pre-login pages as the overall war also contains post-login application & which sometimes is not release ready. Currently, I have got both these parts bundled in the single war project. Please help me by letting me know the best practices whereby I can achieve following: Manage the releases of these two parts independently. I am using Maven. So is there a way I can share the resources, such as CSS, images etc between these two parts. Header and footer of my application is going to be same on pre-login & post-login pages. I was thinking of deploying these apps as two war files in my tomcat container. But then how will I manage the common resources like Css, images etc. Rgds Vijay

• Assign two static IP addresses to one mac address

  - by Timo Ylikännö

  Can Isc-dhcp-server give two static ip addresses to one mac address? I have several home terminals in my network. Each terminal have two interfaces. One for public traffic and one for a management traffic. Both interfaces have same mac address. DHCP server can detect interfaces via dhcp option field and dhcp class declarations. Every terminal have to have static ip address instead of dynamic address. With dynamic address and dynamic pools this would be an easy task. Or is there any dhcp server that can do this?

• Filtering Wikipedia's XML dump: error on some accents

  - by streetpc

  I'm trying to index Wikpedia dumps. My SAX parser make Article objects for the XML with only the fields I care about, then send it to my ArticleSink, which produces Lucene Documents. I want to filter special/meta pages like those prefixed with Category: or Wikipedia:, so I made an array of those prefixes and test the title of each page against this array in my ArticleSink, using article.getTitle.startsWith(prefix). In English, everything works fine, I get a Lucene index with all the pages except for the matching prefixes. In French, the prefixes with no accent also work (i.e. filter the corresponding pages), some of the accented prefixes don't work at all (like Catégorie:), and some work most of the time but fail on some pages (like Wikipédia:) but I cannot see any difference between the corresponding lines (in less). I can't really inspect all the differences in the file because of its size (5 GB), but it looks like a correct UTF-8 XML. If I take a portion of the file using grep or head, the accents are correct (even on the incriminated pages, the <title>Catégorie:something</title> is correctly displayed by grep). On the other hand, when I rectreate a wiki XML by tail/head-cutting the original file, the same page (here Catégorie:Rock par ville) gets filtered in the small file, not in the original… Any idea ? Alternatives I tried: Getting the file (commented lines were tried wihtout success): FileInputStream fis = new FileInputStream(new File(xmlFileName)); //ReaderInputStream ris = ReaderInputStream.forceEncodingInputStream(fis, "UTF-8" ); //(custom function opening the stream, reading it as UFT-8 into a Reader and returning another byte stream) //InputSource is = new InputSource( fis ); is.setEncoding("UTF-8"); parser.parse(fis, handler); Filtered prefixes: ignoredPrefix = new String[] {"Catégorie:", "Modèle:", "Wikipédia:", "Cat\uFFFDgorie:", "Mod\uFFFDle:", "Wikip\uFFFDdia:", //invalid char "Catégorie:", "Modèle:", "Wikipédia:", // UTF-8 as ISO-8859-1 "Image:", "Portail:", "Fichier:", "Aide:", "Projet:"}; // those last always work

• HELP!!! Upgrading to windows 2008 R2 server has caused major issue with screen scraping remote serve

  - by bobsov534

  I have three servers. One is Windows 2003(A) and another is Windows 2008(B) and third one is also Windows 2008 (C). All of them are web servers. A and B contains classic asp pages and they are 32 bit servers and C contains asp.net pages and is 64 bit server. The asp pages of A and B use the screen scraping technology to render the asp.net pages from C. When A is ran, the asp.net page is rendered fine, meaning there are no broken images or file not found error. When B is ran, the images appears to be broken because its looking for those images in Server B instead of Server C itself. I believe this issue is caused by IIS 7 or 7.5 since IIS 6 has no problem scraping the remote server pages. Can you please help me with solution to this problem? This is sort of urgent since upgrading to windows server 2008 R2 now has been a major show stopper for us at the moment. Thanks in advance.

• Admin interface in Rails

  - by yuval

  I have an admin controller located in controllers/admin/admin_controller.rb I also have a pages controller located in controllers/admin/pages_controller.rb pages_controller.rb inherits from admin_controller.rb in routes.rb, I have an admin namespace as such: map.namespace :admin do |admin| admin.resources :pages end I want the admin have basic CRUD functionality in pages_controller.rb (I know how to do that) I want the index and show methods to be available to front-end users I would like the show and index actions to use separate views, but the same code. Questions: Should I create a new pages_controller for the front-end, or share the methods index and show? If share, how would I display separate views depending on whether the url is /admin/pages or /pages If share, should I place pages_controller in /controllers/admin (where it is now) or just in /controllers? Thank you very much.

• SQL Server Clustered Index: (Physical) Data Page Order

  - by scherand

  I am struggling understanding what a clustered index in SQL Server 2005 is. I read the MSDN article Clustered Index Structures (among other things) but I am still unsure if I understand it correctly. The (main) question is: what happens if I insert a row (with a "low" key) into a table with a clustered index? The above mentioned MSDN article states: The pages in the data chain and the rows in them are ordered on the value of the clustered index key. And Using Clustered Indexes for example states: For example, if a record is added to the table that is close to the beginning of the sequentially ordered list, any records in the table after that record will need to shift to allow the record to be inserted. Does this mean that if I insert a row with a very "low" key into a table that already contains a gazillion rows literally all rows are physically shifted on disk? I cannot believe that. This would take ages, no? Or is it rather (as I suspect) that there are two scenarios depending on how "full" the first data page is. A) If the page has enough free space to accommodate the record it is placed into the existing data page and data might be (physically) reordered within that page. B) If the page does not have enough free space for the record a new data page would be created (anywhere on the disk!) and "linked" to the front of the leaf level of the B-Tree? This would then mean the "physical order" of the data is restricted to the "page level" (i.e. within a data page) but not to the pages residing on consecutive blocks on the physical hard drive. The data pages are then just linked together in the correct order. Or formulated in an alternative way: if SQL Server needs to read the first N rows of a table that has a clustered index it can read data pages sequentially (following the links) but these pages are not (necessarily) block wise in sequence on disk (so the disk head has to move "randomly"). How close am I? :)

• Automatically render changed partials in webby

  - by Tomas Sedovic

  I have a webby page and I'm have a layout that all my pages are rendered to. That layout uses a partial for navigation (in HAML): = render(:partial => "navigation", :locals => {:some => "stuff"} ) The problem is that when I change the _navigation partial, neither webby nor webby autobuild recognize the change and they don't re-render the pages. I've solved this by setting the dirty: true flag in the layout, but that makes all the pages re-render every time -- even when nothing changed. I know that this is not that big a deal, but still: is there a way so that when you change partial, webby recognizes this and renders only the affected pages (as it does with everything else)?

• ASP.Net Response Filter Clashing with SharePoint 2010 Publishing Site Defaults

  - by Jason Weber

  Hello everyone, I'm debugging an HttpModule with an ASP.NET response filter. This dynamically rewrites portions of rendered SharePoint WCM pages. The publishing pages render fine in SP2007 on both Server 2003 and Server 2008. However the equivalent pages fail to render in SP2010 B2 on Server 2008 R2 / IIS7. The following error is returned by ASP.NET: Post cache substitution is not compatible with modules in the IIS integrated pipeline that modify the response buffers. Either a native module in the pipeline has modified an HTTP_DATA_CHUNK structure associated with a managed post cache substitution callback, or a managed filter has modified the response. This error is consistent with KB #2014472. However: Caching is disabled for anonymous & authenticated access at the site collection level There do not appear to be any Substitution controls on either the master or layout page The IIS 7 settings are all stock default This is happening e.g. on /pages/default.aspx. It seems likely I'm missing something cache related...but what?

• Can a memory page be moved by modifying the page table?

  - by Adam

  Is it possible (on any reasonable OS, preferably Linux) to swap the contents of two memory pages by only modifying the page table and not actually moving any data? The motivation is a dense matrix transpose. If the data were blocked by page size it would be possible to transpose the data within a page (fits in cache) then swap pages to move the blocks into their final place. A large matrix would have many many pages moved, so hopefully flushing the TLB wouldn't cause trouble.

• Codeigniter MVC controller architecture

  - by justinbach

  I'm building a site using CodeIgniter that largely consists of static content (although there will be a relatively small CMS backend, and there's code to handle localization/internationalization based on the domain used to access it). Typically, in a situation like this, I'd use a Pages controller that is in charge of rendering static content, but as there are a fair number of pages on the site (30+) it'd quickly end up containing lots of methods (assuming one per page). Should I break my Pages controller into multiple controllers (that perhaps inherit from it) according to different sections of the site? Should I organize methods differently in the Pages controller? What's the best practice here? Thanks! Justin
