• Do Url shorteners such as bit.ly serve any purpose in web development?

  - by gath

  I might be missing something here but am unable to understand the true purpose of link shortener services like bit.ly or is it just a lot of hype! Truly if you type nyti.ms on your URL bar on the browser it takes you to www.nytimes.com, but still what is so hard in typing "nytimes.com! which is far much comprehensible to read and understand leave alone to remember! Does shortening URL serve any purpose in web development? Why should someone want use obscure shortened URL?

• How to dynamically insert text from an external file in a Powerpoint slide?

  - by Xavier Nodet

  My goal is to ensure that the C++ code I insert in my presentation compiles correctly. I therefore thought I'd have each example in a separate file (so that I can compile it), and include the text from those files in the Powerpoint slides... I want this 'inclusion' to be dynamic, so that if I change the code in a file, the slides are automatically updated. Is it possible? Will I have to use LaTeX instead of Powerpoint? Any other suggestion about how to solve this problem? Thanks.

• web spidering/crawling, can i do it or just search engines?

  - by bboyreason

  i already had a question answered about web-scraping with wget. but as i read a little more, i realize i may be looking for a web-crawling program. particularly the part about web-crawlers being able to get specific data like links or, in my case, products. all of the products on my site have the following naming convention, website.com/uniqueAlphaNumericID.html as far as i know, no dynamic content generation is being used and only one page per one item in the above format. should i just be thinking about: wget website.com | grep *.html or should i be looking into spiders/crawlers?

• Thunderbird is unable to find server in DHCP controlled network.

  - by Skizz

  I have a network which consists of linux server and a combination of WinXP, Win7 and linux clients. All the systems are given dynamic IP addresses by the router which connects them all together. The server hosts an IMAP mail server. On Win7 and WinXP Thunderbird can access the IMAP server without any problems. On the linux client, using the same IMAP parameters, Thunderbird is unable to connect to the server. How do I get Thunderbird to find the server? I'm not sure if this is a linux system configuration problem or a Thunderbird issue. Additional note: The linux client is running Gnome, the server has a series of Samba shares defined. In the client, doing Places-Connect to Server and selecting Windows Share and specifying the server name, the Samba share is mounted OK.

• How to push text from one UITextfield to another UITextfield in the next View? And back!?

  - by Chrizzz

  an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

  - by user984621

  I bought new router - this one: http://www.tp-link.com/en/products/details/?model=TL-WR841ND and the problem is, that the loading pages is so slow, even sometimes the pages aren't loaded at all. Is the same, when I have on the Mac OS or Windows. Below are the informations from the router-admin section: LAN IP Address: 192.168.2.1 Subnet Mask: 255.255.255.0 WAN IP Address: 192.168.1.100 Dynamic IP Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.254 DNS Server: 89.203.178.2 , 10.14.2.1 How can I fix this problem? Is almost impossible to use the internet this way.

• Why bother to limit the types imported from a python package?

  - by Fast Fish

  When using many IDEs that support autocompletion with Python, things like this will show warnings, which I find annoying: from eventlet.green.httplib import BadStatusLine When switching to: rom eventlet.green.httplib * The warnings go away. What's the benefit to limiting imports to a specific set of types you'll use? Is the parsing faster? Reduces collisions? What other point is there? It seems the state of python IDEs and the nature of the typing system makes it hard for many IDEs to fully get right when a type import works and when it doesn't.

• Nginx proxy to Apache - resolve HTTP ORIGIN

  - by Fratyr

  I have a server setup with nginx serving static content and proxy all PHP/dynamic requests to apache on 127.0.0.1 I'm building an API for my databases, and I need to allow clients by their origin (domain name), rather than just IP. Based on CORS rules. So when I send an HTTP header header("Access-Control-Allow-Origin: www.client-requesting.myapi.com"); from my API server, I have to tell it which origin I allow, otherwise client side requests won't work to my API due to same-origin policy. The question is how can I know which domain name (if any) called my API? What should be the nginx and apache configuration to pass the origin parameter? I tried to google, and all I found is some possible solution with mod_rpaf, but I wanted to be sure. Thanks!

• Two routers, one off-site, same ISP-assigned static IP. A recipe for conflict?

  - by boost

  This is the situation I've inherited: There are two routers, one off-site. Both are connected to the ISP. The ISP assigns both of them the same static IP (or so it seems). Presumably, the network problems we're having are related to the idea that you can't have two instances of the same IP. So we rang up the folk off-site and told them to turn off the router. Now everything's working okay here. How do I get around this? Get another static IP? Figure out how to get the router to ask for a dynamic IP (as we're not using the static IP for anything)?

• Tunneling HTTPS traffic via a PUTTY/SSL tunnel with SOCKS

  - by ripper234

  I have configured a SOCKS ssh tunnel to a remote proxy, and set my Firefox to use localhost:<port> as a SOCKS proxy. My intention is to tunnel outgoing HTTP/S connections from my machine via a specific 3rd party server I own (on AWS). In my testing, HTTP UTLs are forwarded properly (e.g. when I access http://jsonip.com/ from my computer I do get the server's IP) However, whenever I try to reach an HTTPS address, I get this error: The proxy server is refusing connections How do I debug/fix it? My PUTTY tunnel config is simply (some random source port number + dynamic checked): P.S. I'm aware I might need to manually accept SSL certificates. The reason I'm doing this is to resolve problems using gmail as an outbound SMTP service.

• Automatically hide toolbar when it is not in use.

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I am creating a Cocoa Application for Mac OS 10.6 , and I want to hide the toolbar of an NSWindow automatically when it is not in use for at least 30 seconds. I think this can be done with NSTimers, but I'm not familiar with them and I don't know how I can implement this. Another problem is that both the NSToolbarDelegate and NSWindowDelegate protocols don't have delegate methods like toolbarDidShow: Can anyone point me in the right direction? Thanks. PS. This is not to punish the user, but rather give the user a cleaner window (the window consist of only a toolbar for color and font and a text-view). PPS. Can the hide-toolbar-animation lead into a problem with the cursor while the user is typing?

• AsyncTask Threading Rule - Can it really only be used once?

  - by stormin986

  In the documentation on AsyncTask it gives the following as a rule related to threading: The task can be executed only once (an exception will be thrown if a second execution is attempted.) All this means is that you have to create a new instance of the class every time you want to use it, right? In other words, it must be done like this: new DownloadFilesTask().execute(url1, url2, url3); new DownloadFilesTask().execute(url4, url5, url6); Or conversely, you can NOT do the following: DownloadFilesTask dfTask = new DownloadFilesTask(); dfTask().execute(url1, url2, url3); dfTask().execute(url4, url5, url6); Can someone verify this is an accurate interpretation? I realize I pretty much just answered this for myself as I was typing this out... But it wasn't immediately obvious to me so I think this would be useful to have posted nonetheless.

• How to launch a mac application without a terminal window.

  - by KPexEA

  I've written an open-source c++ application and it works fine on Windows and Linux, I finally got a Mac Mini (with 10.5.8) so I've just been testing the Mac version. My application works fine when running it from inside a terminal window and typing ./appname , but if instead I double click on it from the finder, then it opens a termnial window first and then runs my app but it doesn't seem to set the working directory to the correct location so my app dies. How do I make my app so when it launches by being double clicked on it doesn't open a terminal window first and how can I have the current directory set to the apps location automatically?

• Have a doubt on uritemplates in WCF Services

  - by Debby

  I have a webservice with following operation contract and my service is hosted at //localhost:9002/Service.svc/ (I did not put http: before the localhost, as new user can post only one hyperlink) [OperationContract] [WebGet ( UriTemplate = "/Files/{Filepath}" ) ] Stream DownloadFile(string Filepath); This webservice would let users download file, if the proper filepath is provided (assuming, i somehow findout proper filepath). Now, I can access this service from a browser by typing, //localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but i want to send the location of the file. Lets us say users want to download file "C:\Test.mp3" on the server. But how can I pass "C:\Test.mp3" as {Filepath}. I get an error when i type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to webservices and find that quickest way to clear doubts is in this community.

• Accented character replacement for search then reinserted afterwards

  - by user314573

  Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted. My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was. This seems a little brute force to me and I was wondering if anyone had a better alternative? I'm using Visual Studio 2005 with this app. Any advice would be much appreciated! Thanks

• How to make a server check it's own availability on the web?

  - by Javawag

  Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

• automated printouts from a wireless printer

  - by Piotr

  I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

• How to change hybrid disk to basic disk in windows 7?

  - by Marco

  I created a partition E and then deleted the partition. After that I extended my partition C (where OS was installed) to take the space. My partition C became hybrid drive. My hp notebook does not have DVD rom and the notebook only came with an recovery image (I also have a paragon disc image). My computer has some problems now and I want to recover it by either the factory format or the paragon disc image. However, none of them works. I know it is because my disc has become hybrid disk. My question is how to fix the dynamic disk problem?

• How to get a Javascript routine to NOT act if it's in a text box?

  - by talkingnews

  I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test). And in that page is a form, which can have numbers entered as part of a postcode. http://find.talking-newspapers.co.uk/result.php?addressInput=kingston Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good. I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

• Is there a way to automate testing for a GNS3 network topology?

  - by Chedy2149

  I'm working on an MPLS backbone topology using GNS3, this topology includes configuration of several networking technologies such as IPv6, BGP, OSPF, IPv6 to IPv4 dynamic tunneling, MPLS based VPNs, MPLS based traffic engineering... So I'm a beginner with basic knowledge in networking (Ipv4 addressing, basic routing and switching) and I can't just easly test if my topology works or not, moreover fiddling with configuration I've noticed that sometimes when getting MPLS config right and missing BGP config all my topology is messed up. Given that I use Cisco 7200 series routers, is there any way to build a test harness for my topology in order to guarentee correctness with a single push button automated process?

• Reverse Proxy (mod_rewrite) and Rails (absolute paths)

  - by SooDesuNe

  I have front end rails app, that reverse proxies to any of a number of backend rails apps depending on URL, for example http://www.my_host.com/app_one reverse proxies to http://www.remote_host_running_app_one.com such that a URL like http://www.my_host.com/app_one/users will display the contents of http://www.remote_host_running_app_one.com/users I have a large, and ever expanding number of backends, so they can not be explicitly listed anywhere other than a database. This is no problem for mod_rewrite using a prg:/ rewrite map reverse proxy. The question is, the urls returned by rails helpers have the form /controller/action making them absolute to the root. This is a problem for the page served by mod_rewrite because links on the proxied page appear as absolute to the domain. i.e.: http://www.my_host.com/app_one/controller/action has links that end up looking like /controller/action/ when they need to look like /app_one/controller/action mod_proxy_html seems like the right idea, but it doesn't seem to be as dynamic as I would need, since the rules need to be hard coded into the config files. Is there a way to fix this server-side, so that the links will be routed correctly?

• How do I turn off caching in IIS7?

  - by jammus

  Hello. I'm developing an ASP classic site under Windows 7 (form a queue ladies). The problem is IIS seems to be heavily making use of its cache for both static and dynamic content which really conflicts with my 'make a small change, alt-tab, hit ctrl-F5' development style. Changes made to .asp files may take two or three refreshes to show up where as changes to .js files can take 20 times as many. How do I go about turning the caching off on my development machine? Cheers. in b4 stop using asp classic
