• Patenting a Web Application before launch?

  - by SoreThumb

  While discussing a website idea I had with friends and worked on it, they told me to be wary of theft regarding the website. Since the code I'd be working on would be mostly Javascript and HTML, the likelihood of theft is quite high. Furthermore, if I'm lucky, the idea I have would be a breakthrough when it comes to being useful. So, you can see the problem here-- I would be developing an application that's easily stolen, and unfortunately an application that companies larger than myself would want to provide. I'm also unsure if this idea has already been patented. I realize patent law is murky as in you can create a vague patent and still claim others are violating it. So, I'd like to search existing patents for one that may be relevant to my idea, and I'd like to patent it in the meantime. Does anyone have any experience regarding this? Should I invite a lawyer into the mix? As a note, I was going to add tags like, "Patents", but nobody has asked such a question yet and I just joined this StackOverflow...

• Messaging with KnockoutJs

  - by Aligned

  MVVM Light has Messaging that helps keep View Models decoupled, isolated, and keep the separation of concerns, while allowing them to communicate with each other. This is a very helpful feature. One View Model can send off a message and if anyone is listening for it, they will react, otherwise nothing will happen. I now want to do the same with KnockoutJs View Models. Here are some links on how to do this: http://stackoverflow.com/questions/9892124/whats-the-best-way-of-linking-synchronising-view-models-in-knockout http://www.knockmeout.net/2012/05/using-ko-native-pubsub.html ~ this is a great article describing the ko.subscribable type. http://jsfiddle.net/rniemeyer/z7KgM/ ~ shows how to do the subscription https://github.com/rniemeyer/knockout-postbox will be used to help with the PubSub (described in the blog post above) through the Nuget package. http://jsfiddle.net/rniemeyer/mg3hj/ of knockout-postbox   Implementation: Use syncWith for two-way synchronization. MainVM: self.selectedElement= ko.observable().syncWith (“selectedElement”); ElementListComponentVM example: self.selectedElement= ko.observable().syncWith(“selectedElement”); ko.selectedElement.subscribe(function(){ // do something with the seletion change }); ElementVMTwo: self.selectedElement= ko.observable().syncWith (“selectedElement”); // subscribe example ko.postbox.subscribe(“changeMessage”, function(newValue){ }); // or use subscribeTo this.visible = ko.observable().subscribeTo("section", function(newValue) { // do something here }); · Use ko.toJS to avoid both sides having the same reference (see the blog post). · unsubscribeFrom should be called when the dialog is hidden or closed · Use publishOn to automatically send out messages when an observable changes o ko.observable().publishOn(“section”);

• In Windows XP, is it possible to disable user credential caching for particular users

  - by kdt

  I understand that when windows caches user credentials, these can sometimes be used by malicious parties to access other machines once a machine containing cached credentials is compromised, a method known as "pass the hash"[1]. For this reason I would like to get control over what's cached to reduce the risk of cached credentials being used maliciously. It is possible to prevent all caching by zeroing HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\CachedLogonsCount, but this is too indiscriminate: laptops users need to be able to login when away from the network. What I would like to do is prevent the caching of credentials of certain users, such as administrators -- is there any way to do that in Windows XP? http://www.lbl.gov/cyber/systems/pass-the-hash.html

  I made a website on which i need to be able to upload video files and it has worked for quite a while. However after a while it just stopped working and now it will give me the following IIS error message when i upload a video. Images do work (possibly due to their smaller size).

If you have any idea what it could be PLEASE tell me, have been trying to fix this for weeks now. Thanks in advance!

• How do you determine whether a website is a scam [closed]

  - by Tom

  What's the best way to determine if a website is a scam. For example, at first sight (no pun intended) the following website seems to be legitimate. But the price of the product is suspiciously low (all the reviews point to an RRP of approximately £1000). http://www.maxiargos.com/index.php/asus-zenbook-ux31e-dh72-13-3-inch-thin-and-light-ultrabook-silver-aluminum.html Another indication is the lack of SSL for the checkout page, and lack of useful information in the WHOIS record.

• Nginx + PHP-FPM on Centos 6.5 gives me 502 Bad Gateway (fpm error: unable to read what child say: Bad file descriptor)

• What do you need to know to get a job as a web developer [closed]

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.

• Moving from a static site to a CMS with new URLs and meta-data for pages

  - by Chris J

  Hi I am in the process of rebuilding a site from static pages to a CMS which will be using mod_rewrite to generate new page URLs. In this process our marketing people and myself have decided to tidy up the descriptions, keywords and titles. Eg: a page which who's URL is currently "website-name/about_us.html" and has a title of "website-name - something not quite page specific" will change to "website-name/about-us/" and title: "about us - website-name" and may have a few keywords and the description changed. Our goal with updating the meta data is to improve our page rankings and try to keep in line with some best practices for SEO. Though our current page rankings are quite good in many aspects, there is room for improvement. All of the pages will also have content changes (like rearranging heading tags, new menu on all pages, new content in footer, extra pieces of dynamic content relating to other pages). In this new site process I plan to use 301 redirects for all the old URLs pointing to the new URLs. My question is what can I expect to happen to the page rankings in Google, in the sort term and long term? Will this be like kicking off a new site which will have to build up trust over time or will the original page rankings have affect?

• Website visitors are still being redirected after "fixing" the damage from a conditional redirect website attack

  - by Shannon

  BACKGROUND A website of mine was recently the target of a conditional redirect attack. PHP code was added to my pages to redirect visitors. The .htaccess file was edited to redirect visitors. I've re-uploaded my website so the compromised PHP and .htaccess code have both been removed. My site is mostly handwritten php and static HTML content. I don't use page comments or any third party libraries. THE PROBLEM After removing the compromised php and htaccess files, visitors are still being re-directed. What could be the reason that visitors are still being redirected? Are there any tools to check where/how redirects are taking place so I can debug the problem? UPDATE - PROBLEM FIXED As suggested in the comments, I cleared my Firefox cache and that fixed the problem (for me anyway). Visitors with old cache data will obviously still be re-directed.

• How to indicate to a web server the language of a resource

  - by Nik M

  I'm writing an HTTP API to a publishing server, and I want resources with representations in multiple languages. A user whose client GETs a resource which has Korean, Japanese and Trad. Chinese representations, and sends Accept-Language: en, ja;q=0.7 should get the Japanese. One resource, identified by one URI, will therefore have a number of different language representations. This seems to me like a totally orthodox use of content negotiation and multiple resource representations. But when each translator comes to provide these alternate language representations to the server, what's the correct way to instruct the server which language to store the representation under? I'm having the translators PUT the representation in its entirety to the same URI, but I can't find out how to do this elegantly. Content-Language is a response header, and none of the request headers seem to fit the bill. It seems my options are Invent a new request header Supply additional metadata in a multipart/related document Provide language as a parameter to the Content-Type of the request, like Content-Type: text/html;language=en I don't want to get into the business of extending HTTP, and I don't feel great about bundling extra metadata into the representation. Neither approach seems friendly to HTTP caches either. So option 3 seems like the best way that I can think of, but even then it's decidedly non-standard to put my own specific parameters on a very well established content type. Is there any by-the-book way of achieving this?

• How to enable Jetty to support cometd/reverse ajax while let it listen to port 80?

  - by janetsmith

  I would like to use cometd / reverse ajax capability of Jetty 7. I tried to configure it so it listen to port 80, instead of 8080. However, according to http://jetty.mortbay.org/jetty5/faq/faq%5Fs%5F200-General%5Ft%5Fapache.html , Apache can be configured as a HTTP/1.1 proxy to pass selected request to the Jetty using the HTTP/1.1 protocol. This is simple to configure and use, but current versions of the apache mod_proxy do not support persistent connections. As far as I know, the reverse ajax in jetty is depending on continuation (I guess it is persistent connection). So how to let jetty support reverse ajax, while coexist with apache server? Thanks.

• How do I start silverlight on netflix in full screen automatically?

  - by KronoS

  I know that there this great big button that I can click for full screen on the bottom left of the screen. What I'm doing though is launching the direct movie/tv episode in chrome from XBMC using XBMCflicks. It's like pasting the video html address in the address bar and going directly to the video feed. Here's my dilemma, I want a fully working, no need for a keyboard/mouse HTPC, which means I don't want to have to click on the 'full screen' button. Is there a way to run chrome and silverlight automatically in full screen mode when launched?

• LVM mirroring VS RAID1

  - by syrenity

  Hi. Having learned a bit about LVM mirroring, I thought about replacing the current RAID-1 scheme I'm using to gain some flexibility. Problem is that according to what I found on the Internet, LVM is: 1) Slower then RAID-1, at least in reading (as only single volume being used for reading). 2) Non-reliable on power interrupts, and requires disk cache disabling for prevention of data loss. http://www.joshbryan.com/blog/2008/01/02/lvm2-mirrors-vs-md-raid-1/ Also it seems, at least to several setup guides I read (http://www.tcpdump.com/kb/os/linux/lvm-mirroring/intro.html), that one actually requires a 3rd disk for storing the LVM log. This makes the setup completely unusable on 2 disks installations, and lowers the amount of used mirror disks on higher amount of disks. Can anyone comment the above facts, and let me know his experience of using LVM mirroring? Thanks.

• Unable to deactivate windows xp by modifying the license in the registry

  - by ConorWalsh

  I need to deactivate windows xp so I can set it up with a new license. Every tutorial I've visited follow the same steps. (Example http://www.ehow.com/how_6665848_deactivate-windows-xp-pro.html) The tutorials state that the 00BE timer file located in the registry needs to be modified. It is found by going to the registry and navigating through "HKEY_LOCAL_MACHINE," "Software," "Microsoft," "WindowsNT," "CurrentVersion" and "WPAEvents." After the file is modified Windows should be deactivated. However it never does. The value changes but when I run the command to add a new license key it states "windows is already activated". I've done this before on other machines at it worked fine. I can't find any other methods to change the license in XP. Has anyone ever had this issue or knows of another way of deactivating windows?

• Cached css/javascript files on Sun Java System Web Server

  - by Derp

  I'm doing front-end web development in a Solaris 10 / Sun Java System Web Server 7.0U2 environment. I have noticed that changes to static css or javascript files often do not take effect immediately, whereas changes to static html files always do. My best guess is that a default setting in the web server causes it to cache certain file types in order to provide reasonable performance out of the box. I don't have the admin server running--I'll need to edit the config files by hand. What change(s) can I make so that all of my css and javascript edits take effect immediately? Thanks!

• How to set up www cname for free dyndns subdomain

  - by Mk12

  I have a free dyndns domain mk12.gotdns.com How can I set up a cname for www.mk12.gotdns.com to point to mk12.gotdns.com? And how can I force the www one, so that if you navigate to mk12.gotdns.com, it will go to the www one? Note: I don't mean html redirecting, but I think you can do it with url rewriting somehow, something like described here. I've seen many tutorials, but they just vaguely say that you have to enter a cname record, I have no clue what file I need to put it in. Also, please see my question http://stackoverflow.com/questions/1618998/apache-url-rewriting-wont-work about getting url rewriting to work.

• Generate a Word document from list data

  - by PeterBrunone

  This came up on a discussion list lately, so I threw together some code to meet the need.  In short, a colleague needed to take the results of an InfoPath form survey and give them to the user in Word format.  The form data was already in a list item, so it was a simple matter of using the SharePoint API to get the list item, formatting the data appropriately, and using response headers to make the client machine treat the response as MS Word content.  The following rudimentary code can be run in an ASPX (or an assembly) in the 12 hive.  When you link to the page, send the list name and item ID in the querystring and use them to grab the appropriate data. // Clear the current response headers and set them up to look like a word doc.HttpContext.Current.Response.Clear();HttpContext.Current.Response.Charset ="";HttpContext.Current.Response.ContentType ="application/msword";string strFileName = "ThatWordFileYouWanted"+ ".doc";HttpContext.Current.Response.AddHeader("Content-Disposition", "inline;filename=" + strFileName);// Using the current site, get the List by name and then the Item by ID (from the URL).string myListName = HttpContext.Current.Request.Querystring["listName"];int myID = Convert.ToInt32(HttpContext.Current.Request.Querystring["itemID"]);SPSite oSite = SPContext.Current.Site;SPWeb oWeb = oSite.OpenWeb();SPList oList = oWeb.Lists["MyListName"];SPListItem oListItem = oList.Items.GetItemById(myID);// Build a string with the data -- format it with HTML if you like. StringBuilder strHTMLContent = newStringBuilder();// *// Here's where you pull individual fields out of the list item.// *// Once everything is ready, spit it out to the client machine.HttpContext.Current.Response.Write(strHTMLContent);HttpContext.Current.Response.End();HttpContext.Current.Response.Flush();

• Issue with image lightbox and enlargement / Jquery Mobile

  - by Matt

  I'm working on a redesign of my weather website using Jquery Mobile. I have it set up so that you drill down through a series of content containers to get to the weather info (each group of info opens in a dialog display). Everything's worked well, but I've run into an issue with my images. I have them sized so that they fit a mobile device's screen nicely, but because of that, when you look at them in a desktop browser, you can't really make out what the image is. I've tried several image lightbox / enlargement solutions, but for some reason, none of them have worked. Either nothing happens or the images open in a new window. I thought that this might be caused by Jquery Mobile somehow overwriting the scripts and css of the lightbox / enlargements I've tried. I'm not completely sure though that this is the case, and if it is, how I can get around it to be able to enlarge the images to their original size, preferably onclick. Here is a working (for the most part - still some kinks to work out) example. If you look under the "Tropical" section at the "Satellite-Derived Products", you'll see what I mean. http://www.suncoaststormwatch.com/Beta/Index.html

• Dead drive in LVM/XFS configuration

  - by Freddie Witherden

  I had three drives in LVM: a 2 TB drive and two 1 TB drives (added later). One of the 1 TB drives -- I believe the third one -- has died. Spanning all three drives was an XFS partition. Reading: http://www.novell.com/coolsolutions/appnote/19386.html I see that one way of handling this is to replace the dead drive and copy the metadata over. However, I am currently not in possession of a 1 TB drive and can not readily acquire one. Given this, what are my options? There was nothing important on the drives (if there was I would have them in RAID 1) but I would not mind attempting a recovery. Is there a simple way of forcing LVM to go with just two drives and NUL out anything else? (So that fsck can do its thing.)

• Is there a real code-free webpage design tool ?

  - by Sefler

  Recently I was doing web design. I found that the current web design tool (like Expression Web, Dreamweaver) is terribly coupled with code. Though I managed to use HTML, CSS and many others, I found those tool not free enough when came to design. What I want is a totaly code-free design tool with which I can use to draw the layout, paste pictures, add texts and so on. It doesn't need to have functionality to covert the design into code because I can do it myself. That is to say, I need the software to create a blueprint for me. I'm currently using Photoshop to do this. However it is too stupid in displying the layout (It can't show the width and many other attributes, I had to draw them by myself). Can you find one for me? Thanks in advance.

• Hosting and scaling a Facebook application in the cloud? [migrated]

  - by DhruvPathak

  We would be building a Facebook application in Django (Python), but still not sure of where to host it economically, and with a good provision to scale in case the app gets viral. Some details about the app: Would be HTML based like a website,using django as a framework. 100K is the number of expected pageviews in a day, if the app is viral. The users will not generate any media content, only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on Google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment, cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. (Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

• How to copy text out of a PDF without losing formatting?
