  • Changing default REST routes in Rails 3

    - by Vincent
    I need to add one parameter to the default REST route for the show action for SEO purposes: resources :neighborhoods, :only => [:index, :show] neighborhood_url(neighborhood) # => /neighborhoods/lower-east-side I want something like the following: neighborhood_url(city, neighborhood) # => /neighborhoods/manhattan/lower-east-side What would be the easiest way to do this without using nested routes and without breaking Rails REST conventions?

  • Is it possible to access JSON properties with relative syntax when using JSON defined functions?

    - by Justin Vincent
    // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(this.message); } }; myCode.helloWorld(); The above JavaScript code will alert 'undefined'. To make it work for real the code would need to look like the following... (note the literal path to myCode.message) // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(myCode.message); } }; myCode.helloWorld(); My question is... if I declare functions using json in this way, is there some "relative" way to get access to myCode.message or is it only possible to do so using the literal namespace path myCode.message?

  • Implicit constructor available for all types derived from Base excepted the current type?

    - by Vincent
    The following code sum up my problem : template<class Parameter> class Base {}; template<class Parameter1, class Parameter2, class Parameter> class Derived1 : public Base<Parameter> { }; template<class Parameter1, class Parameter2, class Parameter> class Derived2 : public Base<Parameter> { public : // Copy constructor Derived2(const Derived2& x); // An EXPLICIT constructor that does a special conversion for a Derived2 // with other template parameters template<class OtherParameter1, class OtherParameter2, class OtherParameter> explicit Derived2( const Derived2<OtherParameter1, OtherParameter2, OtherParameter>& x ); // Now the problem : I want an IMPLICIT constructor that will work for every // type derived from Base EXCEPT // Derived2<OtherParameter1, OtherParameter2, OtherParameter> template<class Type, class = typename std::enable_if</* SOMETHING */>::type> Derived2(const Type& x); }; How to restrict an implicit constructor to all classes derived from the parent class excepted the current class whatever its template parameters, considering that I already have an explicit constructor as in the example code ? EDIT : For the implicit constructor from Base, I can obviously write : template<class OtherParameter> Derived2(const Base<OtherParameter>& x); But in that case, do I have the guaranty that the compiler will not use this constructor as an implicit constructor for Derived2<OtherParameter1, OtherParameter2, OtherParameter> ? EDIT2: Here I have a test : (LWS here : http://liveworkspace.org/code/cd423fb44fb4c97bc3b843732d837abc) #include <iostream> template<typename Type> class Base {}; template<typename Type> class Other : public Base<Type> {}; template<typename Type> class Derived : public Base<Type> { public: Derived() {std::cout<<"empty"<<std::endl;} Derived(const Derived<Type>& x) {std::cout<<"copy"<<std::endl;} template<typename OtherType> explicit Derived(const Derived<OtherType>& x) {std::cout<<"explicit"<<std::endl;} template<typename OtherType> Derived(const Base<OtherType>& x) {std::cout<<"implicit"<<std::endl;} }; int main() { Other<int> other0; Other<double> other1; std::cout<<"1 = "; Derived<int> dint1; // <- empty std::cout<<"2 = "; Derived<int> dint2; // <- empty std::cout<<"3 = "; Derived<double> ddouble; // <- empty std::cout<<"4 = "; Derived<double> ddouble1(ddouble); // <- copy std::cout<<"5 = "; Derived<double> ddouble2(dint1); // <- explicit std::cout<<"6 = "; ddouble = other0; // <- implicit std::cout<<"7 = "; ddouble = other1; // <- implicit std::cout<<"8 = "; ddouble = ddouble2; // <- nothing (normal : default assignment) std::cout<<"\n9 = "; ddouble = Derived<double>(dint1); // <- explicit std::cout<<"10 = "; ddouble = dint2; // <- implicit : WHY ?!?! return 0; } The last line worry me. Is it ok with the C++ standard ? Is it a bug of g++ ?

  • How to ReHash a password stored into my Database ? (PHP)

    - by Vincent Roye
    Hi! I have some passwords encrypted in my database and I would like to find a way to display them. Here is how they are saved into my mysql database: function generateHash($plainText, $salt = null){ if ($salt === null) { $salt = substr(md5(uniqid(rand(), true)), 0, 25); } else { $salt = substr($salt, 0, 25); } return $salt . sha1($salt . $plainText); } $secure_pass = generateHash($this->clean_password); Then $secure_pass is saved into my database. Anyone would have an idea ?? Thank you very much ;)

  • undo or reverse argsort(), python

    - by Vincent
    Given an array 'a' I would like to sort the array by columns "a.sort(axis=0)" do some stuff to the array and then undo the sort. By that I don't mean re sort but basically reversing how each element was moved. I assume argsort() is what I need but it is not clear to me how to sort an array with the results of argsort() or more importantly apply the reverse/inverse of argsort() Here is a little more detail I have an array a, shape(a) = rXc I need to sort each column aargsort = a.argsort(axis=0) # May use this later aSort = a.sort(axis=0) now average each row aSortRM = asort.mean(axis=1) now replace each col in a row with the row mean. is there a better way than this aWithMeans = ones_like(a) for ind in range(r) # r = number of rows aWithMeans[ind]* aSortRM[ind] Now I need to undo the sort I did in the first step. ????

  • Joomla Site Templates: Architecture Advise

    - by Vincent
    Our client provided us with html templates to turn into a Joomla template, problem is their designs are not Joomla Template friendly where a lot of the html design are not consistent with structure. Currently the only solution we have is applying a template structure pattern that fits the most amount of their design and have seperate joomla templates to take care of the ones that doesn't fit. We have the generic Joomla Template configured with different positions for each div and assign each article to its respective position in the template. Some articles though have menu modules within them so our solution is to split the article into two position and define positions for each menu module. Is this method better than defining module positions within an article content to render menus within an article? Is there a better way of showing articles in specific div positions than having each article be represented by a module to render in a specific div (position) in a template? Right now our current way of rendering an article(s) content to a specific position is to create a module (moduleAsArticle) and define that module a position. Create An Article - Assign A Module To It (moduleAsArticle) - Define that module a position

  • How to check whether iterators form a contiguous memory zone?

    - by Vincent
    I currently have the following function to read an array or a vector of raw data (_readStream is a std::ifstream) : template<typename IteratorType> inline bool MyClass::readRawData( const IteratorType& first, const IteratorType& last, typename std::iterator_traits<IteratorType>::iterator_category* = nullptr ) { _readStream.read(reinterpret_cast<char*>(&*first), (last-first)*sizeof(*first)); return _readStream.good(); } First question : does this function seem ok for you ? As we read directly a block of memory, it will only work if the memory block from first to last is contiguous in memory. How to check that ?

  • List.clear() followed by List.add() not working.

    - by Vincent
    I have the following C# Class/Function: class Hand { private List<Card> myCards = new List<Card>(); public void sortBySuitValue() { IEnumerable<Card> query = from s in myCards orderby (int)s.suit, (int)s.value select s; myCards = new List<Card>(); myCards.AddRange(query); } } On a card Game. This works fine, however, I had trouble at first, instead of using myCards = new List(); to 'reset' myCards, I would use myCards.clear(), however, once I called the clear function, I would not be able to call myCards.add() or myCards.addRange(). The count would stay at zero. Is my current approach good? Is using LINQ to sort my cards good/bad?

  • 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 !!!" ?

  • Google Updates Google Pack – Pushes Firefox and Skype Away

    - by Gopinath
    Google Pack is a must to install software package on every new Windows PC. With a single installer Google Pack delivers all the useful Google applications like Gtalk, Google Earth, Picasa, etc. and third party applications Firefox, Skype, Adobe Reader. Today Google updated Google Pack collection and removed competitor products like Firefox and Skype from main page and pushed them to background. The main page of Google Pack now showcases the following software: Google Apps, Google Picasa, Adobe Reader, Google Toolbar for IE, Google Desktop, avast free antivirus, Google Chrome and Google Earth. It’s still possible to install Firefox and Skype through Google Pack by clicking on the link “All Applicatoins” available on the right side menu and selecting the required installers.  As most of the users use the main page to pick the showcased software, Firefox and Skype are going to loose much of Google Pack love. Thanks labnol This article titled,Google Updates Google Pack – Pushes Firefox and Skype Away, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

  • Putty: Send EOF

    - by joshhendo
    Hi, I'm running Windows 7, and am connecting to a Linux server using Putty. For some programs I'm writing, I need to be able to pass EOF to the input. On Linux I'd normally type Ctrl-Z, but in Putty that seems to exit the program. Ctrl-D doesn't seem to work either. I have had a look at: http://the.earth.li/~sgtatham/putty/0.58/htmldoc/Chapter3.html#using-sysmenu , which suggests looking at http://the.earth.li/~sgtatham/putty/0.58/htmldoc/Chapter4.html#config-telnetkey , though it seems to be if I'm connecting to a Telnet server, which I'm not. Any suggestions on what I could do? Thanks.

  • Wine / PlayOnLinux dependency issues when trying to install

    - by Glutanimate
    I am curious as to why installing PlayOnLinux entails removing seemingly unrelated packages like google-earth-stable. Is this the expected behaviour? This is the output I get when trying to install playonlinux through apt-get: The following packages were automatically installed and are no longer required: python-scour pax ncurses-term Use 'apt-get autoremove' to remove them.

  • See the Lord of the Rings Epic from the Perspective of Mordor [eBook]

    - by ETC
    Much like the wildly popular book “Wicked” mixed up the good/bad dichotomy in the Wizard of Oz, “The Last Ring-Bearer” shows us the Mordor’s take on the Lord of the Rings. The work of a Russian paleontologist, Kirill Yeskov, “The Last Ring-Bearer” frames the conflict in the Lord of the Rings from the perspective of the citizens of Mordor. Salon magazine offers this summary, as part of their larger review: In Yeskov’s retelling, the wizard Gandalf is a war-monger intent on crushing the scientific and technological initiative of Mordor and its southern allies because science “destroys the harmony of the world and dries up the souls of men!” He’s in cahoots with the elves, who aim to become “masters of the world,” and turn Middle-earth into a “bad copy” of their magical homeland across the sea. Barad-dur, also known as the Dark Tower and Sauron’s citadel, is, by contrast, described as “that amazing city of alchemists and poets, mechanics and astronomers, philosophers and physicians, the heart of the only civilization in Middle-earth to bet on rational knowledge and bravely pitch its barely adolescent technology against ancient magic.” Hit up the link below to grab a PDF of the official English translation of Yeskov’s work.

  • What is up with the Joy of Clojure 2nd edition?

    - by kurofune
    Manning just released the second edition of the beloved Joy of Clojure book, and while I share that love I get the feeling that many of the examples are already outdated. In particular, in the chapter on optimization the recommended type-hinting seems not to be allowed by the compiler. I don't know if this was allowable for older versions of Clojure. For example: (defn factorial-f [^long original-x] (loop [x original-x, acc 1] (if (>= 1 x) acc (recur (dec x) (*' x acc))))) returns: clojure.lang.Compiler$CompilerException: java.lang.UnsupportedOperationException: Can't type hint a primitive local, compiling:(null:3:1) Likewise, the chapter on core.logic seems be using an old API and I have to find workarounds for each example to accommodate the recent changes. For example, I had to turn this: (logic/defrel orbits orbital body) (logic/fact orbits :mercury :sun) (logic/fact orbits :venus :sun) (logic/fact orbits :earth :sun) (logic/fact orbits :mars :sun) (logic/fact orbits :jupiter :sun) (logic/fact orbits :saturn :sun) (logic/fact orbits :uranus :sun) (logic/fact orbits :neptune :sun) (logic/run* [q] (logic/fresh [orbital body] (orbits orbital body) (logic/== q orbital))) into this, leveraging the pldb lib: (pldb/db-rel orbits orbital body) (def facts (pldb/db [orbits :mercury :sun] [orbits :venus :sun] [orbits :earth :sun] [orbits :mars :sun] [orbits :jupiter :sun] [orbits :saturn :sun] [orbits :uranus :sun] [orbits :neptune :sun])) (pldb/with-db facts (logic/run* [q] (logic/fresh [orbital body] (orbits orbital body) (logic/== q orbital)))) I am still pulling teeth to get the later examples to work. I am relatively new programming, myself, so I wonder if I am naively looking over something here, or are if these points I'm making legitimate concerns? I really want to get good at this stuff like type-hinting and core.logic, but wanna make sure I am studying up to date materials. Any illuminating facts to help clear up my confusion would be most welcome.

  • What to do about "system running in low-graphics mode"?

    - by ubuntubabe
    My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.

  • Web map services displaying poorly

    - by user29261
    Web map services no longer display correctly in ArcGIS and Google Earth - no one else on network is experiencing these. Using windows 7 OS. These problem began abruptly (1 day they were working, the next they were not). Specific problems include not displaying at all; correct display on 10% of the monitor and repeating lines of coloured squiggles and text on the remaining 90%; and small, widely spaced, pixels in place of colour fill. Links where this occurs: arcgis http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en Google earth http://openmaps.gov.bc.ca/kml/BCGov_Web_Map_Library.kml I can't pinpoint any changes to the computer setup which may have prompted this, however, adding arcgis 10.1 SP 1 occured around the same time. Probably just a coincidence. Anyone had similar problems? or solutions to these? Thanks for any thoughts. Jim

  • OEG11gR2 integration with OES11gR2 Authorization with condition

    - by pgoutin
    Introduction This OES use-case has been defined originally by Subbu Devulapalli (http://accessmanagement.wordpress.com/).  Based on this OES museum use-case, I have developed the OEG11gR2 policy able to deal with the OES authorization with condition. From an OEG point of view, the way to deal with OES condition is to provide with the OES request some Environmental / Context Attributes.   Museum Use-Case  All painting in the museum have security sensors, an alarm goes off when a person comes too close a painting. The employee designated for maintenance needs to use their ID and disable the alarm before maintenance. You are the Security Administrator for the museum and you have been tasked with creating authorization policies to manage authorization for different paintings. Your first task is to understand how paintings are organized. Asking around, you are surprised to see that there isno formal process in place, so you need to start from scratch. the museum tracks the following attributes for each painting 1. Name of the work 2. Painter 3. Condition (good/poor) 4. Cost You compile the list of paintings  Name of Painting  Painter  Paint Condition  Cost  Mona Lisa  Leonardo da Vinci  Good  100  Magi  Leonardo da Vinci  Poor  40  Starry Night  Vincent Van Gogh  Poor  75  Still Life  Vincent Van Gogh  Good  25 Being a software geek who doesn’t (yet) understand art, you feel that price(or insurance price) of a painting is the most important criteria. So you feel that based on years-of-experience employees can be tasked with maintaining different paintings. You decide that paintings worth over 50 cost should be only handled by employees with over 20 years of experience and employees with less than 10 years of experience should not handle any painting. Lets us start with policy modeling. All paintings have a common set of attributes and actions, so it will be good to have them under a single Resource Type. Based on this resource type we will create the actual resources. So our high level model is: 1) Resource Type: Painting which has action manage and the following four attributes a) Name of the work b) Painter c) Condition (good/poor) d) Cost 2) To keep things simple lets use painting name for Resource name (in real world you will try to use some identifier which is unique, because in future we may end up with more than one painting which has the same name.) 3) Create Resources based on the previous table 4) Create an identity attribute Experience (Integer) 5) Create the following authorization policies a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience OES Authorization Configuration We do need to create 2 authorization policies with specific conditions a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience We don’t need an explicit policy for Deny access to all paintings for employees with less than 10 year of experience, because Oracle Entitlements Server will automatically deny if there is no matching policy. OEG Policy The OEG policy looks like the following The 11g Authorization filter configuration is similar to :  The ${PAINTING_NAME} and ${USER_EXPERIENCE} variables are initialized by the "Retrieve from the HTTP header" filters for testing purpose. That's to say, under Service Explorer, we need to provide 2 attributes "Experience" & "Painting" following the OES 11g Authorization filter described above.

  • How to convert many-to-one XML data to DataSet?

    - by TruMan1
    I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value. What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML: <responses> <response> <properties id="1" Form="Account Request" Date="Tuesday, March 16, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain1.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="2" Form="Account Request" Date="Tuesday, March 17, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John2</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain2.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="3" Form="Account Request" Date="Tuesday, March 18, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John3</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain3.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="4" Form="Account Request" Date="Tuesday, March 19, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain4.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> </responses> How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms? Then row 1 would be: John, [email protected], http://domain1.com, 999-999-9999, Earth, Misc, , True How can I do this with the XML provided?

  • calculating a gps coordinate given a point, bearing and distance

    - by user530509
    Hello, I have a problem which draws my back in some project for some time now. Im basically looking to trap a polygon using x,y points drawn by some script ive written. lat1,lon1 are the center gps cords of the polygon and im looking for its surrounding polygon. here is a part of my code in python: def getcords(lat1,lon1,dr,bearing): lat2=asin(sin(lat1)*cos(dr)+cos(lat1)*sin(dr)*cos(bearing)) lon2=lon1+atan2(sin(bearing)*sin(dr)*cos(lat1),cos(dr)-sin(lat1)*sin(lat2)) return [lat2,lon2] my input goes like this: lat1,lon1 - are given in decimal degrees. -dr is the angular computed by dividing the distance in miles by the earth's -raiuds(=3958.82) -bearing between 0-360 degrees. however for the input getcorsds1(42.189275,-76.85823,0.5/3958.82,30) i get [-1.3485899508698462, -76.8576637627568], however [42.2516666666667,-76.8097222222222] is the right answer. as for the angular distance i calculate it simply by dividing the distance in miles by the earth's raiuds(=3958.82). anybody?

  • Is there an algorithm for determining how much daylight there is?

    - by Pharaun
    Is there a function/algorithm that allows me to input the latitude and the approximate orbital position of the earth in so that I can determine how long the sun is up? IE during the winter it would show that the sun is only up a few hours in the far north hemisphere. I did some basic Google search and didn't find much so I was thinking that I might have to do some trigonometry that would allow me to calculate how much the earth is inclined or not toward the sun then use that information along with the latitude to figure out how much sunshine a site would be getting.

  • A basic animation not showing up

    - by Rilakkuma
    I still try different basics with android, and now I'm stuck with animation. I'm trying to implement a simple animation. I've defined animation in xml file like this: alpha android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" duration="3000" repeatCount="infinite" In my main view group I have an ImageView defined like this: <ImageView android:id="@+id/someb" android:src="@drawable/earth_normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5dip"/> And this is from my starting activity class: public class Ohayou extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView earth = (ImageView)findViewById(R.id.someb); Animation earthFadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fade_in); earth.startAnimation(earthFadeInAnimation); } It finds ImageView successfuly and creates animation. but when I start emulator ImageView just shows the original src image, not an animation. What am I doing wrong? Thanks
