• Has anyone seen an HTTP 500 error when HTTPS traffic going through Pound Proxy forwards to an HTTP page?

  - by scientastic

  We have Varnish as our load balancer and reverse proxy cache for normal HTTP traffic. For HTTPS traffic, we use Pound proxy to unwrap the SSL and forward to Varnish, which then forwards to the back-end servers. This is used for our "checkout" process to encrypt credit card info in transition. However, on the last stage of checkout, users are always getting an HTTP 500 (Internal Server) error. It doesn't seem to be due to our back-end app server, by all tests I've tried. Does anyone know anything about how that transition works-- the transition back from HTTPS to HTTP and the interaction between Pound and Varnish-- and why it might cause 500 errors?

• how can a web page change my mouse speed?

  - by Tekaholic

  I usually have many tabs open in Firefox and I haven't been able to find one specific website that causes this because I don't seem to notice it right away. I'm going to click on something on my desktop and I am lifting up the mouse several times to get across the screen. It doesn't seem to matter what program I might be using because this happens on all desktops and in Firefox, too. So I go in my settings and I turn up the mouse speed all the way and it's still not really acceptable. It doesn't matter if I click on different tabs but when I close the browser, my mouse is way too sensitive, like I'd expect at the max setting. Then I go back to Control Center and return my mouse speed and acceleration to normal. When I restart my browser, the mouse remains normal. So is there something to this before I start wasting my time hunting through my history to discover which website or sites are having this effect? ...and if it is a specific site and I locate it, what can I change to stop it's effect on my mouse besides not visiting it? I am using Linux Mint 13 on a box with an AMD Athlon processor and 2gigs of ram. I never installed another browser because everything works for me.

• How can we compute the LAST page with JPA?

  - by Kevin

  I would like to implement pagination in my Servlet/EJB/JPA-Hibernate project, but I can't figure out how only one page from the query and know the number of pages I must display I use setFirstResult(int first) ; setMaxResults(int max) ; and that's working alright, but how can I know how many pages I will have in total? (Hibernate is my JPA provider, but I would prefer using only JPA if possible) UPDATE: COUNT() seems to be the better/easiest solution; but what can be the cost of SELECT COUNT(*) FROM ... in comparison with executeQuery("SELECT * FROM ...).getListResult().size() ?

• Program for scanning, saving and restoring window position?

  - by hellbell.myopenid.com

  Is there some program for scanning, saving and restoring last window position? For example at this moment i have opened five window first is google chrome which is not opened at full screean but at half of display, second is notepad which is on right side, and third is cmd which is under notepad. So I want to use this combination of "layout" when primary using google chrome (surfing at internet), but if working primary at other program let's say word (writting text) i want to use other program and at different position (cause is effectivly). So the point is to easy switching from one "layout" to another. (Like in many program that support more modes, for example visual studio - debug layout, - coding layout, etc ...)

• Is there a way to get a reference to all the paragraphs or headings in a web page in JavaScript?

  - by mattbd

  I'm writing a simple Greasemonkey script to strip out all the images, headings and paragraphs from a web page (it's because someone wants to use images of several popular websites with the images and text removed in a presentation about branding of websites). I've figured out how to do so with images by using a for loop and the document.images array like this: var i = 0; var imglngth = document.images.length; for(i=0;i<imglngth;i++) { document.images[i].style.display="none"; } However, I don't believe there's an object representing paragraphs or headers. Any suggestions as to how I could implement this?

• how to call functions/methods within CMS block or page?

  - by latvian

  Hi, We are trying to make all our blocks and pages static so that designer or anyone else can easily change the content or design of the website, however. There is a feature that uses our own custom module. So, the template that we want to make static is calling methods out of our custom block, for example, <!--some html code--> ..... <?php $this->helpMeBePartOfCMS(); ?> ..... <!--some html code--> How do i incorporate these method calls inside cms block or page? Thank you

• Silverlight "Out of browser application" vs. "Install from page"

  - by Matt McMinn

  I’ve been working on integrating some controls which call in to COM classes in to a Silverlight client. Since my controls use COM, they only work out of browser. The client does have out of browser installation options turned on, and when I launch the client from visual studio, I can right click it, and install it to the desktop. That all seems to be working fine. The strange part though is that my controls don’t work when they’re out of browser – I get an error that the COM server can’t be started. The stranger part is that if I go in to the clientproperties, and set the Start Action from “Dynamically generate a test page” to “Out of browser application”, my controls work fine, and I get no COM errors. So I guess I don’t understand the difference between installing the application to the desktop through the right click menu and setting the application to start as an out of browser application. Any idea what's going on here?

• web-development: how do you usually handle the "under costruction" page"?

  - by Patrick

  hi, I was wondering what's the best way to switch a website to a temporary "under costruction" page and switch it back to the new version. For example, in a website, my customer decided to switch from Joomla to Drupal and I had to create a subfolder for the new CMS, and then move all the content to the root folder. 1) Moving all the content back to the root folder always create some problems with file permissions, links, etc... 2) Creating a rewrite rule in .htaccess or forward with php is not a solution because another url is shown including the top folder. 3) Many host services do not allow to change the root directory, so this is not an option since I don't have access to apache config file. Thanks

• How do I add events to nested server controls? (ASP.Net)

  - by bert

  I am building a custom master page type control i.e. sort of like a datagrid but should be easier to add custom functionality into it. It's going great but part of the desired functionality is to have a paging control that switches on and off and part of that control would be a textbox that displays the current page number and on TextChanged redirects to the new page of the dataset. The problem I'm having is that technically the textbox which has its event fired is embedded in a control that is embedded in the control you actually put on the page sort of like Page  | Display Control  | Paging Control  | Textbox Buried all the way down there the event is not firing. Worse the postback javascript isn't even being written onto the page (Nothing on the page posts back so far this is the only bit that really needs to). I've been trawling around Google for quite a while now and picked up that I need to implement INamingContainer (done) and I need to add the control into the page's control tree (is Pre_Init too late for that? When's a good time to Add the Control to the page?) then the event should fire, apparently. But I've been unable to find an example of best practice on this there are quite a few near misses where people are having button angst but this isn't a button. So can anyone point me in the direction of getting a control embedded in a control embedded in a control added to a page to behave properly?

• Throw blank even-numbered/left pages

  - by TimGJ

  I am trying to typeset a large document using ReportLab and Python 2.7. It has a number of sections (about 6 in a 1,000 page document) and I would like each to start on odd-numbered/right-hand page. I have no idea though whether the preceding page will be odd or even and so need the ability to optionally throw an additional blank page before a particular paragraph style (like you sometimes get in manuals where some pages are "intentionally left blank"). Can anyone suggest how this could be done, as the only conditional page break I can find works on the basis of the amount of text on the page not a page number. I also need to make sure that the blank page is included in the PDF so that double-sided printing works.

• How to access web page hierarchy inside a application.

  - by Hazior

  Trying to figure out how to programmatically access the web pages in the application. Just something simple like a list of them would be awesome. I know I can create a list but I was wondering if there was something that could 'look' at the pages and add a new one to the list if you make a new page for the application. Example with 7 pages: Error Default Login Content Users ContactUs Admin I am half awake so I may be a little unclear. Maybe puting it all in a single question will be easier. How do you autogenerate a list of all webpages in your current application?

• Can the Browser 'Forward' Button be Set from HTML?

  - by John C

  Example: At the bottom of the StackOver Questions page are a bunch of page numbers (1,2,3...), enclosed in a set of prev and next buttons. Clicking next repeatedly will bring me to, say page 5, at which point I will have: The page's prev button will be set to 'http://stackoverflow.com/questions?page=4' The Back button on my Browser will have the same value. The page's next button will be set to 'http://stackoverflow.com/questions?page=6' The Forward button on my Browser - won't be set to anything. Obviously, if I hit the Back button on the Browser, then Forward will have a value, pointing to the URL for page 5 - but not otherwise. Is there any way, from HTML (plus Javascript), to set the value of the Browser's Forward button? Or is this one of those things that HTML is simply forbidden to do?

• How to refer to the true 'body' of a page? [NOT iFrame body]

  - by Jim

  I have a script that create a new div element. Then, I want to append the div to the body of the page using appendChild method. The script is look like this : var div = document.createElement('div'); div.id = 'newdiv'; document.body.appendChild(div); Unfortunately, the div also appended to the body of iframes. So, my question is, how to refer to the true body of the document, not including the body of the iframes? That way, the div just appended once, to the "true body" of the document. Thanks before, and sorry if my english is bad. :-D

• How to create a snapshot or clone of PHP, MySQL page... Inspiration needed

  - by jimbo

  Hi, We have a web application that creates a dynamic PHP page with all the MySQL stored details a user has entered via a number a forms. So far so good, but we want this information stored some how to be refereed to at a later date, as an administrator can make changes to the data, which reflects on calculations that are worked out from this saved data. When going back over this saved data we need to be able to see all the information submitted for that particular calculation, so if that data has changed we will see what is was relating to that calculation. Now we have thought about maybe a snapshot when the calculation is done, pdf of the webpage or something similar would do, but is this simple to do? I hope this makes sense...

• How to determine page generation time with Struts 2 ?

  - by Samuel_xL

  I'm using Struts 2 and I'd like to determine the page generation time without an external profiler. I can easily profile the actions execute() method, but I don't know how to include the time spent before (in dispatchers, interceptors...) and after (time taken by the servlet corresponding to the view ("jsp time")). Is there simple way to do this ? And if there isn't, how could I, at least, profile the "jsp time" (maybe a tag I'm not aware of ?) ? I think it would be accurate enough to just take in account action time + jsp time. Thanks.

• How to make bottom half of a page take up remaining height?

  - by RobVious

  I've searched and tried a bunch of different things. I have a variable-height tophalf, and the bottom half should fill up the remaining space. A JSfiddle: http://jsfiddle.net/UCJmQ/ CSS: .top { background-color: lightblue; height: 300px; } .bottom { background-color: green; min-height: 100px; overflow: hidden; height: 100%; } html, body { height: 100%; } HTML: <div class="top"></div> <div class="bottom"> </div> What I'm seeing now is the green page taking up the entire window's height, not the remaining height. How can I make it take the remaining height instead?

• Passing multiple Vertex Attributes in GLSL 130

  - by Roy T.

  (note this question is closely related to this one however I didn't fully understand the accepted answer) To support videocards in laptops I have to rewrite my GLSL 330 shaders to GLSL 130. I'm trying to do this but somehow I don't get vertex attributes to work properly. My 330 shaders look like this: #version 330 layout(location = 0) in vec4 position; layout(location = 3) in vec4 color; smooth out vec4 theColor; void main() { gl_Position = position; theColor = color; } Now this explicit layout is not allowed in GLSL 130 so I referenced this page to see what the default layouts for some values would be. As you can see position should be the 0th vertex attribute and color should be the 3rd vertex attribute. Because this is a test case I had already configured my explicit layouts in the same way, which worked, so I now simply rewrote my shader to this and expected it to work: #version 130 smooth out vec4 theColor; void main() { gl_Position = gl_Vertex; theColor = gl_Color; } However this doesn't work, the value of gl_Color is always (1,1,1,1). So how should I pass multiple vertex attributes to my GLSL 130 shaders? For reference, this is how I set my vertex buffer object and attributes (I've just adapted this tutorial to JAVA+JOGL) gl.glBindBuffer(GL3.GL_ARRAY_BUFFER, vertex_buffer_id); gl.glEnableVertexAttribArray(0); gl.glEnableVertexAttribArray(3); gl.glVertexAttribPointer(0, 4 , GL3.GL_FLOAT, false, 0, 0); gl.glVertexAttribPointer(3, 4, GL3.GL_FLOAT, false, 0, 4*4*4); gl.glDrawArrays(GL3.GL_TRIANGLE_STRIP, 0, 4); gl.glDisableVertexAttribArray(0); gl.glDisableVertexAttribArray(3); EDIT I solved the problem by querying for the layout locations of position an color using glGetAttribLocation however I still don't understand why the 'hardcoded' values like gl_Color didn't work, can't I upload data in there as normal? Shouldn't they be used?

• ADF Bounded Taskflow Activation

  - by Vijay Mohan

  hey guys, It's really been a while since I last blogged. Just came across a hard-to-debug scenario, so thought of sharing it for the benefit of ADF developers.I had a page fragment(jsff) wrapped inside a  bounded taskflow, for which the activation was conditional and was based on a requestScope property (be it a requestScope variable or a property coming from a requestScope bean). As soon as the taskflow activates and page renders the requestScope parameters life span ends. After that, when you raise an event inside the page (click of commandLink, moseHover, valueChange event etc) then for the first time the event gets fired but it fails to affect the change in the page, moreover, for the subsequent times the event itself doesn't get fired. Any guesses as to what could be the culprit..?I guess, I already gave the reason in the initial paragraph. For the first time when the event gets fired, the fwk sees that the page is already lying in inactivate state, so it fails to affect the change and for subsequent times it doesn't even fire the event because it already knew that the page/region is inactive. So, in such a scenario we must use either a pageFlowScope property or transientVO property which could exist till the page's life span.

• Understand how the TLB (Translation Lookaside buffer) works and interacts with pagetable and addresses

  - by Darxval

  So I am trying to understand this TLB (Translation Lookaside Buffer). But I am having a hard time grasping it. in context of having two streams of addresses, tlb and pagetable. I don't understand the association of the TLB to the streamed addresses/tags and page tables. a. 4669, 2227, 13916, 34587, 48870, 12608, 49225 b. 12948, 49419, 46814, 13975, 40004, 12707 TLB Valid Tag Physical Page Number 1 11 12 1 7 4 1 3 6 0 4 9 Page Table Valid Physical Page or in Disk 1 5 0 Disk 0 Disk 1 6 1 9 1 11 0 Disk 1 4 0 Disk 0 Disk 1 3 1 12 How does the TLB work with the pagetable and addresses? The homework question given is: Given the address stream in the table, and the initial TLB and page table states shown above, show the final state of the system also list for each reference if it is a hit in the TLB, a hit in the page table or a page fault. But I think first i just need to know how does the TLB work with these other elements and how to determine things. How do I even start to answer this question?
