• How to convert a url to a browser like url? ( ...%20... )

  - by Kaoukkos

  I want to get data using CURL but I have a problem. When I set the url like this $url = "https://graph.facebook.com/fql?q=SELECT name FROM page"; // continues I do not have anything returned. When I copy the browser url, this is $url = "https://graph.facebook.com/fql?q=SELECT%20name%20FROM%20page"; I get the results through CURL. I tried htmlentities and htmlspecialchars without luck. What am I missing here? $ch = curl_init($url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); $content = curl_exec($ch);

• FFT in MATLAB: wrong 0Hz frequency

  - by roujhan

  Hello I want to use fft in MATLAB to analize some exprimental data saved as an excell file. my code: A=xlsread('Book.xls'); G=A'; x=G(2, : ); N=length(x); F=[-N/2:N/2-1]/N; X = abs(fft(x-mean(x),N)) X = fftshift(X); plot(F,X) But it plots a graph with a large 0Hz wrong component, my true frequency is about 395Hz and it is not shown in the plotted graph. Please tell me what is wrong. Any help would be appreciated.

• Interpolation on Cubism graphs

  - by Abe Stanway

  Cubism was designed, by mbostock's own words, for maximum information density - which means it generally wants to display one datapoint per pixel. While this is useful in many cases, it doesn't help when your data itself is not that dense. In these cases, you get ugly, staccato-style graphs like so: Is there a way to interpolate my data/graph within Cubism to show a nice, smoothed graph? EDIT: After adding keepLastValue to the metric, I get this: Here is the same data as shown in Graphite: I would like to smooth the Cubism view to look more like Graphite (with the added awesomeness of the horizon overplotting)

• Is there a transformation matrix that can scale the x and/or y axis logarithmically?

  - by Dave M

  I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a prefab matrix for flipping). I want to be able to graph these waveforms on a log scale as well (either x axis or y axis or both), but I'm not sure if this is even possible to do with a matrix transformation. Does anyone know if this is possible, and if it is, what is the matrix?

• Purely functional equivalent of weakhashmap?

  - by Jon Harrop

  Weak hash tables like Java's weak hash map use weak references to track the collection of unreachable keys by the garbage collector and remove bindings with that key from the collection. Weak hash tables are typically used to implement indirections from one vertex or edge in a graph to another because they allow the garbage collector to collect unreachable portions of the graph. Is there a purely functional equivalent of this data structure? If not, how might one be created? This seems like an interesting challenge. The internal implementation cannot be pure because it must collect (i.e. mutate) the data structure in order to remove unreachable parts but I believe it could present a pure interface to the user, who could never observe the impurities because they only affect portions of the data structure that the user can, by definition, no longer reach.

• Deadlock Problem because of an Update Lock.

  - by Randy Minder

  We have a deadlock issue we're trying to track down. I have an deadlock graph (xdl) generated from Profiler. It shows the losing SQL statement as a simple Select statement, not an Update, Delete or Insert statement. The graph shows the losing Select statement as requesting a Shared lock on a resource **but also owning an Update lock on a resource**. This is what is baffling me. Why would a Select statement that is not part of an Insert, Update or Delete ever hold an Update lock on a resource? I should add that the Update lock it owns is on the table being selected against by the losing Select statement.

• I think I don't understand git branches

  - by Hans

  Salutations everyone, I have been working on a bash script as a small summer project to learn more about UNIX scripting and on using git. This has been the first time that I have used branches in git, normally I just stick to master. I was viewing the git log with the graph (git log --graph) when I noticed that my 'develop' branch seemed to have merged with 'master'. Something like this: master ----1--------3----4----5----6----HEAD develop \---2---/ but commits 3 onwards were done within the develop branch. Doing git checkout master and git checkout develop showed this to be true. What exactly is going on? Is this what is known as fast-forwarding? P.S.: Commits 1 and 2 are also a mystery to me being that commit 2 is actually an amendment of commit 1 (as far I thought, I used this advice)

• linq with Include and criteria

  - by JMarsch

  How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

• Split a sting array into a number array in javascript

  - by Wesley Skeen

  I am reading a value from a dropdown list depending on what option is selected. I am using jqPlot to graph the values. jqPlot expects an array of values like [91, 6, 2, 57, 29, 40, 95] but when I read the value in from the dropdown box it is coming in as a whole string "[91, 6, 2, 57, 29, 40, 95]" I tried splitting it but I got ["91", "6", "2", "57", "29", "40", "95"] which wont display the graph correctly. Is there anybody that has encountered something like this before and what can I do to make my values convert into a number array. Thanks for any help

• openvpn and selective routing

  - by mx2323

  hi everyone, whats the best way to configure openvpn clients to go selectively go about using an openvpn connection? i want to setup a vpn server for friends in china, but i dont want them to use it for everything, just so they can access sites like youtube, facebook, cnn, etc. while they are in china through the vpn (these are blocked). it would be nice if the vpn was a backup, so for instance if they are trying to go to facebook (which is blocked), it would go through the vpn connection once finding that the normal connection does not work. this would save a lot of bandwidth cost actually, and give them a better browsing experience. is this a iptable route thing? or a dns server that i push to my clients?

• How can I duplicate, or copy a Core Data Managed Object?

  - by 106480833665852483906

  I have a managed object ("A") that contains various attributes and types of relationships, and its relationships also have their own attributes & relationships. What I would like to do is to "copy" or "duplicate" the entire object graph rooted at object "A", and thus creating a new object "B" that is very similar to "A". To be more specific, none of the relationships contained by "B" (or its children) should point to objects related to "A". There should be an entirely new object graph with similar relationships intact, and all objects having the same attributes, but of course different id's. There is the obvious manual way to do this, but I was hoping to learn of a simpler means of doing so which was not totally apparent from the Core Data documentation. TIA!

• Generate page dynamically & insert body into another page - is this realistic?

  - by DaveDev

  I have the requirement to create a page which contains a graph at the top, and for each item in the graph there's a fact sheet below. I already produce the fact sheets as stand-alone pages. Now, rather than recreating the fact sheet to include in the page I have to create, I'd like to use the work that already exists. Is it realistic that I dynamically generate each fact sheet as needed, strip out the body and insert that into the new page? If so, does anyone have any pointers or suggestions? Thanks

• Haskell - generating all paths between nodes

  - by user1460863

  I need to build a function, which return all paths between certain nodes. connect :: Int -> Int-> [[(Int,Int)]] Data.Graph library gives me usefull function 'buildG' which builds graph for me. If I call let g = buildG (1,5) [(1,2),(2,3),(3,4),(4,5),(2,5)], I will get an array where every node is mapped to his neighbours. An example: g!1 = [2] g!2 = [3,5] .. g!5 = [] I was trying to do it using list comprehensions, but I am not very good in haskell and I am getting typing error which I can't repair. connect x y g | x == y = [] | otherwise = [(x,z) | z <- (g!x), connect z y g] I don't need to worry at this moment about cycles. Here is what I want to get: connect 1 5 g = [[(1,2),(2,3),(3,4),(4,5)],[(1,2),(2,5)]]

• Inventory Management OOP design

  - by rgamber

  This was an OOP design and implementation interview question, which I came across on glassdoor.com. Design and implement a inventory management system to minimize the number of missed delivery dates while keeping costs to the company low. Of course there is no right answer to this, but I am not sure I understand the question correctly and am wondering what would be a good answer. Is this as simple as creating an undirected graph with nodes as the delivery points, and edges having weights as the cost of the delivery, and then use a single-source-shortest-path algorithm (like Dijkstras, or Bellman-Ford) on the graph? Not sure if this type of question should be asked here,so let me know and I will delete it.

• Microsoft launches IE9 preview – No support for XP

  - by samsudeen

  Microsoft launched the developer preview version of Internet Explorer 9 (IE9) at MIX 10 web conference yesterday.This release is aimed getting the feedback from website designers , developers and other community to make IE9 development better from its previous versions. Microsoft will update the developer preview every eight weeks and the next update is expected on mid of march.So what is new and interesting  about IE9 Chakra Chakra (The new scripting engine of IE9) renders the Java script much faster compared to IE8 and other browsers thus improving the performance significantly.According to Microsoft Chakra renders the java script in background with a separate thread parallel to the main engine which is complete new way of rendering from the current browser technologies Standards Microsoft is desperate to make ( surprisingly!!!) IE9 compliance to  web standards by supporting the open standards such as Accelerated support for HTML5 video support for new web technologies such as CSS3 and SVG2. ACID3 Test IE9 scores (55/100) in its latest ACID3 test which is much better compared to the IE8 score (22/100) but not even  nearer to their rivals Chrome, Opera, and Safari which scores 100/100 in ACID3 testing I am little disappointed over not able to download the  developer preview on my XP machine. The early comments looks much positive for IE9.If you want to explore IE9,check the Microsoft Test drive site  at Microsoft IE9 Test-drive You can also download the IE9 developer preview at Download Preview Join us on Facebook to read all our stories right inside your Facebook news feed.

• How To Restore Firefox Options To Default Without Uninstalling

  - by Gopinath

  Firefox plugins are awesome and they are the pillars for the huge success of Firefox browser. Plugins vary from simple ones like changing color scheme of the browser to powerful ones likes changing the behavior of the browser itself. Recently I installed one of the powerful Firefox plugins and played around to tweak the behavior of the browser. At the end of my half an hour play, Firefox has completely become useless and stopped rending web pages properly. To continue using Firefox I had to restore it to default settings. But I don’t like to uninstall and then install it again as it’s a time consuming process and also I’ll loose all the plugins I’m using. How did I restore the default settings in a single click? Default Settings Restore Through Safe Mode Options It’s very easy to restore default settings of Firefox with the safe mode options. All we need to do is 1.  Close all the Firefox browser windows that are open 2. Launch Firefox in safe mode 3. Choose the option Reset all user preferences to Firefox defaults 4. Click on Make Changes and Restart button. Note: When Firefox restore the default settings, it erases all the stored passwords, browser history and other settings you have done. That’s all. This excellent feature of Firefox saved me from great pain and hope it’s going to help you too. Join us on Facebook to read all our stories right inside your Facebook news feed.

  - by samsudeen

  Sputnik the JavaScript 3 conformance test suite launched by Google last year is now available as Google Labs (Sputnik Test)product. You can browse it like any other  website and run over 5000 java script function tests to check your browser compatibility This product allows you do the following options Run :  You can run the complete test suite on your browser to check the compliance to  ECMA-262 standards.You can also browse trough  the failed test case. Compare : You can compare java script conformance of the various leading browsers in the market. Now web developers can be more cautious while designing websites to make them compatible with multiple browsers. Google is committed to review and release multiple version periodically with updated test cases. According to the latest sputnik test  result released by Google, Opera 10.5 leads the race with only 78 failures. Microsoft IE 8 performed the worst (463 failures) . Next to Opera,  Apple’s Safari (159 failures), Google’s Chrome (218 failures) and Mozilla’s Firefox (259 failures) leads respectively Though the test are about conformance, not performance, the top 3 leading browsers are among the last three in conformance which is something they have to improve Join us on Facebook to read all our stories right inside your Facebook news feed.

• SQL SERVER – A Puzzle – Illusion – Confusion – April Fools’ Day

  - by pinaldave

  Today is April 1st and just like every other year, I like to bring something interesting and light for the day. Atleast there should be days in every one’s life when they should feel easy. Here is a quick puzzle for you and I believe it will make you feel extremely smart if you can figure out the result behind the same. Run following in SQL Server Management Studio and observe the output: SELECT 30.0/(-2.0)/5.0; SELECT 30.0/-2.0/5.0; Here are few questions for you: 1) What will be the result of above two queries? 2) Why? If you think you can figure out the result without executing them – I encourage you to execute BOTH of them in SSMS and see if they give you same result or different result. Well, now I am waiting for your answer here – why? I often post similar things on my facebook page http://facebook.com/SQLAuth – you are welcome to play with me there.

• Learning HTML5 - Sample Sites

  - by Albers

  Part of the challenge with HTML5 is understanding the range of different technologies and finding good samples. The following are some of the sites I have found most useful. IE TestDrive http://ie.microsoft.com/testdrive/ A good set of demos using touch, appcache, IndexDB, etc. Some of these only work with IE10. Be sure to click the "More Demos" link at the bottom for a longer list of Demos in a nicely organized list form. Chrome Experiments http://www.chromeexperiments.com/ Chrome browser-oriented sumbitted sites with a heavy emphasis on display technologies (WebGL & Canvas) Adobe Expressive Web http://beta.theexpressiveweb.com/ Adobe provides a dozen HTML5 & CSS3 samples. I seem to end up playing the "Breakout" style Canvas demo every time I visit the site. Mozilla Demo Studio https://developer.mozilla.org/en-US/demos/tag/tech:html5/ About 100 varied HTML5-related submitted web sites. If you click the "Browse By Technology" button there are other samples for File API, IndexedDB, etc. Introducing HTML5 samples http://html5demos.com/ Specific Tech examples related to the "Introducing HTML5" book by Bruce Lawson & Remy Sharp HTML5 Gallery http://html5gallery.com/ HTML5 Gallery focuses on "real" sites - sites that were not specifically intended to showcase a particular HTML5 feature.
