• What GC parameters is a JVM running with?

  - by skaffman

  I'm still investigating issues I have with GC tuning (see prior question), which involves lots of reading and experimentation. Sun Java5+ JVMs attempt to automatically select the optimal GC strategy and parameters based on their environment, which is great, but I can't figure out how to query the running JVM to find out what those parameters are. Ideally, I'd like to see what values of the various GC-related -XX options are being used, as selected automatically by the VM. If I had that, I could have a baseline to begin tweaking. Anyone know to recover these values from a running VM?

• Getting the image URL without the HTML in Rails

  - by tesmar

  Hi, In Rails is there a way to get the URL to the image (going through the assets_host) and just return the URL of the image? I want to use assets_host data in my Javascript, but I just need to insert the URL into the JS, not the whole image_tag. Thank you in advance!

• Absolute URL Generation with Subdirectory in Rails

  - by Hulihan Applications

  Hey Guys - I'm trying to find an easy way(without having to write any plugins or overrides to Rails) to generate an absolute url to a rails application being in a subdirectory. This url is going to be generated for theme images, not links, so I can't url link_to or url_for. Here's an example of what I want to do: <%= theme_image("delete_icon.png", :theme => "my_theme") %> If my app is running at http://localhost, This would return: <img src="/themes/my_theme/images/delete_icon.png"> but If my app is running at http://localhost/myapp, This would return: <img src="/myapp/themes/my_theme/images/delete_icon.png"> Can anyone point me in the right direction to generate a dynamic, absolute url to a non-routed resource?

• Using YQL and Jquery to check URL validity

  - by user102533

  The answer in this post http://stackoverflow.com/questions/2119680/use-jquery-to-check-if-a-url-on-another-domain-is-404-or-not shows how to use YQL in Jquery to check if URL is valid or not. However, I can't get this to work for me. The only difference I can think of is that my URL is a text file (http://mycrossdomain.com/sometext.txt) and not HTML.I think the YQL query needs to be adjusted accordingly. Any help is appreciated.

• Template or function arguments as implementation details in doxygen?

  - by Vincent

  In doxygen is there any common way to specify that some C++ template parameters of function parameters are implementation details and should not be specified by the user ? For example, a template parameter used as recursion level counter in metaprogramming technique or a SFINAE parameter in a function ? For example : /// \brief Do something /// \tparam MyFlag A flag... /// \tparam Limit Recursion limit /// \tparam Current Recursion level counter. SHOULD NOT BE EXPLICITELY SPECIFIED !!! template<bool MyFlag, unsigned int Limit, unsigned int Current = 0> myFunction(); Is there any doxygen normalized option equivalent to "SHOULD NOT BE EXPLICITELY SPECIFIED !!!" ?

• Is there a way to look up the Publishers URL using the linkshare.com API

  - by steve

  I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

• Get URL parameter function that gets value of url part or returns true if it's there but with no val

  - by LLer

  I'm using the following function to get a URL parameter. function gup(name, url) { name = name.replace(/[\[]/, '\\\[').replace(/[\]]/, '\\\]'); var results = new RegExp('[\\?&]'+name+'=?([^&#]*)').exec(url || window.location.href); return results == null ? null : results[1]; } It works only if the parameter has a value, for example. gup('a', 'http://example.com/page.php?a=1&b=2'); will return 1. But if I try gup('a', 'http://example.com/page.php?a&b=2'); It returns null. I want it to return true because parameter "a" exists in that url, even though it has no value it's still there and gup() should return true. Could I get a bit of help rewriting this? I'm not that good with regex.

• How to pass multiple params to function in python?

  - by user1322731

  I am implementing 8bit adder in python. Here is the adder function definition: def add8(a0,a1,a2,a3,a4,a5,a6,a7,b0,b1,b2,b3,b4,b5,b6,b7,c0): All function parameters are boolean. I have implemented function that converts int into binary: def intTObin8(num): bits = [False]*8 i = 7 while num >= 1: if num % 2 == 1: bits[i] = True else: bits[i] = False i = i - 1 num /= 2 print bits return [bits[x] for x in range(0,8)] I want this function to return 8 bits. And to use this two functions as follows: add8(intTObin8(1),intTObin8(1),0) So the question is: How to pass 8 parameters using one function?

• How can I represent URL (possibly including query string) as a filename in Java without obscuring the original URL?

  - by jerluc

  Is there any real way to represent a URL (which more than likely will also have a query string) as a filename in Java without obscuring the original URL completely? My first approach was to simply escape invalid characters with arbitrary replacements (for example, replacing "/" with "_", etc). The problem is, as in the example of replacing with underscores is that a URL such as "app/my_app" would become "app_my_app" thus obscuring the original URL completely. I have also attempted to encode all the special characters, however again, seeing crazy %3e %20 etc is really not clear. Thank you for any suggestions.

• Helicon ISAPI_REWRITE for masking folder

  - by Brian

  Hello, I would like to use the ISAPI_REWRITE module to rewrite a url: www.site.com/app/ to www.site.com So that the user doesn't see the folder where the application is... the reason why isn't important, but essentially I need to mask this folder due to an IIS structure change. Any help would be appreciated. I need to remap any requested file in the app directory and any related subdirectory to the main URL. Thanks.

• Is there a way to have a virtual directory in iis 7 point to another domain?

  - by Dan Appleyard

  Let us say I have two subdomains: http://content.mydomain.com and http://app.mydomain.com. http://content.mydomain.com is pointing at a different server than http://app.mydomain.com is. Is there a way to get a url of http://app.domain/content to point to http://content.mydomain.com without the url in the browser changing to the subdomain? I am trying to get this to work in IIS 7 / 6 and am having issues. Any advice would be greatly appreciated!

• Chrome Equivalent of %s address bar trick in Firefox

  - by notbrain

  I was curious if there was an equivalent technique in Chrome to do address bar param string replacement like you can do in Firefox. If you create a bookmark and put a %s in the bookmark URL/address part, and set a keyword for the bookmark, you can do things like URL: http://php.net/%s Keyword: php Type in browser: php fopen End up at: http://php.net/fopen Is this making its way into Chrome or is there a way to do it?

• Do browsers change URLs of saved bookmarks in response to 301 redirection?

  - by elliot100

  HTTP status code 301 is used to indicate that content has moved permanently, and that the returned URL should be used to access the requested content in future. RFC 2616 says Clients with link editing capabilities ought to automatically re-link references to the request-URI to one or more of the new references returned by the server, where possible. Do any browsers actually implement this and change a bookmark's URL?

• Need to open links in new tab in ie8 !

  - by BHOdevelopper

  I have a sidebar (right sided iframe) and when i click on a link in it, it opens a new window in IE8, (in firefox it open a new tab). What do i need to do to open links in IE8 in a new tab. I already set the Tools-Internet Options-Settings- 'Always open pop-ups in a new tab' and 'A new tab in the current window' open in new tab but still doesn't work. My links are pretty simple, what am i missing ? exemple: text. Also some site are saying to register Regsvr32 actxprxy.dll to fix this problem, still doesn't work. And i want this to work with a simple click, no 'right-click-open in new tab' option. I also hope i won't get the 'can't change how ie8 works' answer. ;)

• Preventing access to files if a user types the full url on the address bar

  - by bogha

  i have a website, some folders on the websites contains images and files like .pdf , .doc and .docx . the user can easly just type the address in the url to get the file or display the photo http://site/folder1/img/pic1.jpg then boom.. he can see the image or just download the file my question is: how to prevent this kind of action, how can i guarantee a secure access of the files. any suggestions UPDATE TO CLARIFY MY IDEA i don't want any user who is browsing the website to get access to these files normally by just writing the URL of the file. those files are a CV files, they are being uploaded by the users to a specific folder on the server which we host outside the company. those files are only being viewed by the HR people through a special system. that's the scenario we want. i don't want a WEB GEEK who just wants to see what files has been uploaded to this folder to download them easly to his/her computer and view them or publish them on the internet. i hope you got my idea

• Looking for a comprehensive/"expert" guide to BCD parameters

  - by Stilez

  I'm interested in educating myself about BCD on Windows 8. There are many, many "walkthrough" guides" and "howtos", but I can't find any guides at typical "enthusiast" level covering what each option or argument in a BCD /ENUM dump might mean, and the principles governing how these all work together. Imagine trying to rebuild or debug BCD (including EFI/BIOS variants and recovery/hibernate/memtest sections, and perhaps multiple boot Windows/WinPE/WinRE) from scratch using just BCDedit + DiskPart, and trying to understand rather than just copy/pasting commands. That's roughly the knowledge I'm after. Example questions might be: How is a BCD /ENUM dump to be read, item by item? How do its sections work together? (A lot of guides only show a specific example rather than explaining all the all common args that can exist and what they mean, they don't actually explain how sections work together, or they assume MBR/BIOS/Vista/7 and omit info needed for EFI/GPT/Dynamic disks/8) Partitions are specified by volume letter or as a \Device\HarddiskVolumeNNN. Why does it sometimes show these items as a letter and sometimes as a GUID? What are the practical differences if any? What exactly is syntax like "ramdisk=[C:]\Images\winpe.wim,{ramdiskoptions}" saying, and how will the drive letter "C" be interpreted at runtime in a line like this? Is the drive in such a line always "C:" (most examples assume so) and if not, when wouldn't it be? Many websites state that an sdi device and path may be needed in some sections of BCD, but what is sdi and what are these args doing when they appear? How does the GUID to HDD volume/partition mapping work under EFI/GPT? So that if disks or partitions/volumes change it's clear how one can confirm from basic principles whether data shown in BCD /ENUM ALL is still correct or not. Does anyone know of a suitable reference source for this kind of raw BCD data and structures? Thanks!

• Getting around url block for game

  - by Josh T

  So I play a game called Battlefield Play4Free (www.battlefield.play4free.com). Its essentially a giant browser plugin. The admin on my computer used to have the url battlefield.play4free.com/en/playnow.html blocked which only blocked the page that launches the game (i found a way to launch the game without going to that page and the game worked fine). Now it blocks battlefield.play4free.com which thus blocks all subpages. However, I have found that if I change it to an https and go to https://battlefield.play4free.com/en/login.html to login and then https://battlefield.play4free.com/en/playnow.html I can launch the game. However, when the game launches the borders and everything show but the window content is just a giant blockpage (the same one that shows up when I go to battlefield.play4free.com in the browser) and the blocked page is battlefield.play4free.com (main page). Is there any way I can get around this? I need a way to make the game access the server without going through the browser i.e. make the game use a proxy to get the data or somehow get past the besafe block. I was thinking perhaps you could get around it if you could get the game to make a direct request to the server and not through the url/browser, I know this works because I have a torrenting app that even tho torrent sites are blocked in the browser, the app makes a direct request and thus is not blocked. By the way, the program that blocks everything is besafe or besecure something like that. I do have access to an admin account (on the computer not the besafe program) as well as router access and pretty much anything else. Thanks so much!

• Embedding a WMV file on the web via URL in a Powerpoint presentation

  - by Dave

  I've got a situation where I want to distribute a Powerpoint presentation to several people. I want to be able to embed several large videos in this presentation by linking to a URL, for the following specific reasons: the videos are highly confidential, and I would like to be able to delete them at some later date, but still allow them to see it in the presentation while it is online. I want to send the presentation via email (so it should be small), and put the links on a server with a faster upload speed Maybe I'd like to change the video at some point without changing the presentation One option that addresses #1 is to hook up a webcam and allow them to see video stream from the office, but our upload rate is too slow for this to be a viable option. I've tried embedding a video and giving Powerpoint the URL. It seems to work initially, because the first frame appears in my slideshow. However, when I play the slideshow, nothing happens. I looked at the network traffic on my computer, and nothing was getting downloaded from the remote server. Any suggestions on how to make this work, or how to at least satisfy the criteria listed above would be great!
