Vote count: 0 Consider the following code public class myClass{ myClass instanceOfNotYetDefinedClass; ... //etc code } I don't understand how the compiler manages to understand that: I'm telling it to create a class, and then it says: "OK! Let me see what this myClass class has. Oh, its a myClass, let me see whats this has..." etc. It may be a pretty noobish question, but I really don't understand how this could be handled. asked 2 mins agoYoTengoUnLCD Let's block ads! بخوانید...

Vote count: 0 right now im using Processing IDE to some image processing and im using Visual Studios 2013 to do some speech analysis and the idea is that when a image gets process it will send a string to visual studios and when visual studios hears a specific word it will send a string to Processing. The biggest problem i face is the fact that Processing dont like to share serial, i mean i can't have processing open while Arduino's serial monitor open to read what's being sent from Processing and the same thing will happen if i have Processing serial ruing in a sketch and then i open visual studios and if i say something the program is made to transmit a string and when that sending starts ...

Vote count: 0 I'm using Flow Router and Blaze Renderer for a simple website (think blog / brochureware). I'm using FlowRouter.path() to create links on my menu elements. The url changes as expected when these links are clicked and the action() method on the route is fired. However the templates don't seem to be refreshed and the template helpers aren't fired. The route in my /lib/route.js file is const about = FlowRouter.group({ prefix: '/about' }); about.route('/:pageSlug/:subSectionSlug', { action: (params) => { console.log('action() fired :' + params.pageSlug + ' :' + params.subSectionSlug); BlazeLayout.render( 'applicationLayout', { main: 'basicPage', }); }, name: 'pageSubsection', }); T...

Vote count: 0 I am indexing PDF documents in elasticsearch without using the official plugin, I am using a PHP library to parse PDF content into plain text. This PHP library allows me to get the document content by pages so I would like my search page would retrieve some highlight similar to: [Page 1] ... Highlighted text from the search ... [Page 4] ... Highlighted text from page 4 that match with the search ... The mapping they gave to me is like this, I just converted text from string to array: properties: { highlight:{ text: [ "Page1Content...", "Page2Content...", "Page3Content...", ...], other_fields: {} }, other_fields: {} } But I caot find a way to get the array indexes when getting t...

Vote count: 0 I'm developing an application that requires some initial configuration when first deploying(initial params, server adress,...etc). This application is written in a different language than python, but I'm using python because it's the language that's the most commonly pre-installed on linux machines. I'm thinking of installing the prerequisites at the top of the script like so: import os os.system("python setup.py install ") from import But then I'm installing a package on a computer that belongs to a user, only to use it just once. Should I just uninstall it when my script ends? How do I go about this? asked 1 min agoJelle Criel Let's block ads! بخوانید...

Vote count: 0 SQLite only has a few data types: NULL, INTEGER, REAL, TEXT, BLOB Meanwhile, the JDBC has: -7 BIT, -6 TINYINT, -5 BIGINT, -4 LONGVARBINARY, -3 VARBINARY, -2 BINARY, -1 LONGVARCHAR, 0 NULL, 1 CHAR, 2 NUMERIC, 3 DECIMAL, 4 INTEGER, 5 SMALLINT, 6 FLOAT, 7 REAL, 8 DOUBLE, 12 VARCHAR, 91 DATE, 92 TIME, 93 TIMESTAMP, 1111 OTHER. (possibly more) I can't find any documentation anywhere for the SQLite-specific JDBC driver, and I need to know how the driver maps the types. Obviously null is null,integer is integer (probably),real is real (probably),but what do text and blob map to? asked 2 mins agoEric the Red Let's block ads! بخوانید...

Vote count: 0 I have this assignment where I'm supposed to use a custom array list. I am quite confused about lists and generics. In the template for our code we're given "private myObj[] objects;", which is from the class myObj.java which only contains attribute of type T called "data". "private myObj[] objects;" looks a lot like an array to me. I thought generics didn't get along with arrays. I tried casting to be able to create enough "space" for 10 elements of type T(generic), but I couldn't do this without compiler errors which only go away when I comment out the casting of an array of type myObj of size 10 as "myObj[]". Help me please. My TA's have not answered my questions. asked 1 mi...

Vote count: 0 I'm trying to create a cesar cipher in Javascript and having trouble figuring out how to do the shift.

Vote count: 0 Context: Bower is cool. It is downloading the configured things with all their dependencies to my wwwroot/lib folder. However it is required to have those files also be the part of the Visual Studio solution for multiple reasons, just to name some: intellisense, Resharper, publish. Question: How to include the downloaded files to the VS solution automatically? (Note, this must be automated, as the upgrades/updates can contain new/removed files, so if I had to check this after every time when bower looks for updates than I am in big trouble...) Related Question: Bower downloads many things related to a dependency (I mean src, less, etc). This is cool, but obviously a big impact ...

However, I understand that to create dynamic websites, other languages are required. Would it be better to lea PHP or Java? Are there alteatives? I'm really interested in how social networking platforms work and would like to explore it for my EPQ (extended project qualification) for my A-Levels as well as taking CS.
