  • load data from grid row into (pop up) form for editing

    - by user1495457
    I read in Ext JS in Action ( by J. Garcia) that if we have an instance of Ext.data.Record, we can use the form's loadRecord method to set the form's values. However, he does not give a working example of this (in the example that he uses data is loaded into a form through a file called data.php). I have searched many forums and found the following entry helpful as it gave me an idea on how to solve my problem by using form's loadRecord method: load data from grid to form Now the code for my store and grid is as follows: var userstore = Ext.create('Ext.data.Store', { storeId: 'viewUsersStore', model: 'Configs', autoLoad: true, proxy: { type: 'ajax', url: '/user/getuserviewdata.castle', reader: { type: 'json', root: 'users' }, listeners: { exception: function (proxy, response, operation, eOpts) { Ext.MessageBox.alert("Error", "Session has timed-out. Please re-login and try again."); } } } }); var grid = Ext.create('Ext.grid.Panel', { id: 'viewUsersGrid', title: 'List of all users', store: Ext.data.StoreManager.lookup('viewUsersStore'), columns: [ { header: 'Username', dataIndex: 'username' }, { header: 'Full Name', dataIndex: 'fullName' }, { header: 'Company', dataIndex: 'companyName' }, { header: 'Latest Time Login', dataIndex: 'lastLogin' }, { header: 'Current Status', dataIndex: 'status' }, { header: 'Edit', menuDisabled: true, sortable: false, xtype: 'actioncolumn', width: 50, items: [{ icon: '../../../Content/ext/img/icons/fam/user_edit.png', tooltip: 'Edit user', handler: function (grid, rowIndex, colIndex) { var rec = userstore.getAt(rowIndex); alert("Edit " + rec.get('username')+ "?"); EditUser(rec.get('id')); } }] }, ] }); function EditUser(id) { //I think I need to have this code here - I don't think it's complete/correct though var formpanel = Ext.getCmp('CreateUserForm'); formpanel.getForm().loadRecord(rec); } 'CreateUserForm' is the ID of a form that already exists and which should appear when user clicks on Edit icon. That pop-up form should then automatically be populated with the correct data from the grid row. However my code is not working. I get an error at the line 'formpanel.getForm().loadRecord(rec)' - it says 'Microsoft JScript runtime error: 'undefined' is null or not an object'. Any tips on how to solve this?

  • My Rails session is getting reset when I have concurrent requests

    - by alex_c
    I think I might be misunderstanding something about Rails sessions, so please bear with me, I might not be phrasing my question the best way. I'm working on an iPhone app with a Ruby on Rails backend. I have a web view which by default goes to the index action of one controller (and uses sessions), and in the background a bunch of API calls going to a different controller (and which don't need to use sessions). The problem is, the sessions set by my web view seem to be overwitten by the API calls. My staging server is pretty slow, so there's lots of time for the requests to overlap each other - what I see in the logs is basically this: Request A (first controller) starts. Session is empty. Request B (second controller) starts. Session is empty. Request A finishes. Request A has done authentication, and stored the user ID in the session. Session contains user ID. Request B finishes. Session is empty. Request C starts. Session is empty - not what I want. Now, the strange thing is that request B should NOT be writing anything to the session. I do have before and after filters which READ from the session - things like: user = User.find_by_id(session[:id]) or logger.debug session.inspect and if I remove all of those, then everything works as expected - session contents get set by request A, and they're still there when request C starts. So. I think I'm missing something about how sessions work. Why would reading from the session overwrite it? Should I be accessing it some other way? Am I completely on the wrong track and the problem is elsewhere? Thank you for any insights!

  • How to force my method to accept objects from external software?

    - by Roman
    I have a method which needs to take a callback object as an argument and then (at the moment when it's needed) my method will call a specific method of the callback object. I wrote a class called Manager which has a method called addListener. As the argument for this method I need to use a callback object which is defined by the external software. So, I define the addListener in the following way: public void addListener(Listener listener). Of course Eclipse complains because it does not know what Listener is (because the Listener is defined by the external software). The only think that I know (should know) about the Listener is that it has a method called doSomething. So, to pleasure Eclipse I add an interface before my Manager class: interface Listener { void doSomething(); } public class CTManager { ... The problem seems to be solved but then I try to test my software. So, I create a class called test. In this class I create an instance of the Manager class and try to use addListener method of this instance. I also create a class Listener, instantiate it and give the instance to the addListener. And it's the place where the problem appears. Eclipse writes that addListener is not applicable to the given argument. I think it's because it expect something from my Listenr interface but gets something from the Listener class. How can I solve this problem?

  • C++: IDE Code assistance (Linux)

    - by Martijn Courteaux
    Hi, My IDE (NetBeans) thinks this is wrong code, but it compiles correct: std::cout << "i = " << i << std::endl; std::cout << add(5, 7) << std::endl; std::string test = "Boe"; std::cout << test << std::endl; He always says: unable to resolve identifier .... (.... = cout, endl, string); So I think it has something to do with the code assistance. I think I have to change/add/remove some folders. Currently, I have this include folders: C compiler: /usr/local/include /usr/lib/gcc/i486-linux-gnu/4.4.3/include /usr/lib/gcc/i486-linux-gnu/4.4.3/include-fixed /usr/include C++ compiler: /usr/include/c++/4.4.3 /usr/include/c++/4.4.3/i486-linux-gnu /usr/include/c++/4.4.3/backward /usr/local/include /usr/lib/gcc/i486-linux-gnu/4.4.3/include /usr/include Thanks

  • Why can't we just use a hash of passphrase as the encryption key (and IV) with symmetric encryption algorithms?

    - by TX_
    Inspired by my previous question, now I have a very interesting idea: Do you really ever need to use Rfc2898DeriveBytes or similar classes to "securely derive" the encryption key and initialization vector from the passphrase string, or will just a simple hash of that string work equally well as a key/IV, when encrypting the data with symmetric algorithm (e.g. AES, DES, etc.)? I see tons of AES encryption code snippets, where Rfc2898DeriveBytes class is used to derive the encryption key and initialization vector (IV) from the password string. It is assumed that one should use a random salt and a shitload of iterations to derive secure enough key/IV for the encryption. While deriving bytes from password string using this method is quite useful in some scenarios, I think that's not applicable when encrypting data with symmetric algorithms! Here is why: using salt makes sense when there is a possibility to build precalculated rainbow tables, and when attacker gets his hands on hash he looks up the original password as a result. But... with symmetric data encryption, I think this is not required, as the hash of password string, or the encryption key, is never stored anywhere. So, if we just get the SHA1 hash of password, and use it as the encryption key/IV, isn't that going to be equally secure? What is the purpose of using Rfc2898DeriveBytes class to generate key/IV from password string (which is a very very performance-intensive operation), when we could just use a SHA1 (or any other) hash of that password? Hash would result in random bit distribution in a key (as opposed to using string bytes directly). And attacker would have to brute-force the whole range of key (e.g. if key length is 256bit he would have to try 2^256 combinations) anyway. So either I'm wrong in a dangerous way, or all those samples of AES encryption (including many upvoted answers here at SO), etc. that use Rfc2898DeriveBytes method to generate encryption key and IV are just wrong.

  • C++ MACRO that will execute a block of code and a certain command after that block.

    - by Poni
    void main() { int xyz = 123; // original value { // code block starts xyz++; if(xyz < 1000) xyz = 1; } // code block ends int original_value = xyz; // should be 123 } void main() { int xyz = 123; // original value MACRO_NAME(xyz = 123) // the macro takes the code code that should be executed at the end of the block. { // code block starts xyz++; if(xyz < 1000) xyz = 1; } // code block ends << how to make the macro execute the "xyz = 123" statement? int original_value = xyz; // should be 123 } Only the first main() works. I think the comments explain the issue. It doesn't need to be a macro but to me it just sounds like a classical "macro-needed" case. By the way, there's the BOOST_FOREACH macro/library and I think it does the exact same thing I'm trying to achieve but it's too complex for me to find the essence of what I need. From its introductory manual page, an example: #include <string> #include <iostream> #include <boost/foreach.hpp> int main() { std::string hello( "Hello, world!" ); BOOST_FOREACH( char ch, hello ) { std::cout << ch; } return 0; }

  • Timestamps and Intervals: NUMTOYMINTERVAL SYSTDATE CALCULATION SQL QUERY

    - by MeachamRob
    I am working on a homework problem, I'm close but need some help with a data conversion I think. Or sysdate - start_date calculation The question is: Using the EX schema, write a SELECT statement that retrieves the date_id and start_date from the Date_Sample table (format below), followed by a column named Years_and_Months_Since_Start that uses an interval function to retrieve the number of years and months that have elapsed between the start_date and the sysdate. (Your values will vary based on the date you do this lab.) Display only the records with start dates having the month and day equal to Feb 28 (of any year). DATE_ID START_DATE YEARS_AND_MONTHS_SINCE_START 2 Sunday , February 28, 1999 13-8 4 Monday , February 28, 2005 7-8 5 Tuesday , February 28, 2006 6-8 Our EX schema that refers to this question is simply a Date_Sample Table with two columns: DATE_ID NUMBER NOT Null START_DATE DATE I Have written this code: SELECT date_id, TO_CHAR(start_date, 'Day, MONTH DD, YYYY') AS start_date , NUMTOYMINTERVAL((SYSDATE - start_date), 'YEAR') AS years_and_months_since_start FROM date_sample WHERE TO_CHAR(start_date, 'MM/DD') = '02/28'; But my Years and months since start column is not working properly. It's getting very high numbers for years and months when the date calculated is from 1999-ish. ie, it should be 13-8 and I'm getting 5027-2 so I know it's not correct. I used NUMTOYMINTERVAL, which should be correct, but don't think the sysdate-start_date is working. Data Type for start_date is simply date. I tried ROUND but maybe need some help to get it right. Something is wrong with my calculation and trying to figure out how to get the correct interval there. Not sure if I have provided enough information to everyone but I will let you know if I figure it out before you do. It's a question from Murach's Oracle and SQL/PL book, chapter 17 if anyone else is trying to learn that chapter. Page 559.

  • Can you do this with Hudson?

    - by damian
    I want to create a hudson job, that takes an id as a parameter. And use that id to calculate the svn-repo path. Where I work you have a svn path for every issue that you resolve. And then all the issues are joined into a single svn-path. What I want to do is to run static code analysis on the partial issues. So I think maybe having an Ant build.xml that I use for every issue, then, parametrize the job with the issue id. I have tried to achieve that but the svn path doesn't replace the parameter. I have tried with #issueId, %issueId%, ${issueId} and ${env.issueId} without success. Jump error like: Location 'http://svn-path:8181/svn/devSet/issues/${env.chuid}' does not exist Checking out a fresh workspace because C:\Documents and Settings\dnoseda\.hudson\jobs\test\workspace\${env.chuid} doesn't exist Checking out http://svn-path:8181/svn/devSet/issues/${env.chuid} ERROR: Failed to check out http://svn-path:8181/svn/devSet/issues/${env.chuid} org.tmatesoft.svn.core.SVNException: svn: '/svn/!svn/bc/46190/devSet/issues/$%7Benv.chuid%7D' path not found: 404 Not Found (http://svn-path:8181) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:64) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:51) at I am think that I can not do what I want.

  • CDN for Images in ASP.NET

    - by Chris
    I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN. An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup: <img src='<%= GetImagePath()/image.png' /> I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work. Any thoughts or ideas on how to implement this?

  • Work with AJAX response with DOM methods

    - by Stomped
    I'm retrieving an entire HTML document via AJAX - and that works fine. But I need to extract certain parts of that document and do things with them. Using a framework (jquery, mootools, etc) is not an option. The only solution I can think of is to grab the body of the HTML document with a regex (yes, I know, terrible) ie. <body>(.*)</body> put that into the current page's DOM in a hidden element, and work with it from there. Is there an easier/better way? Update I've done some testing, and inserting an entire HTML document into a created element behaves a bit differently across browsers I've tested. For example: FF3.5: keeps the contents of the HEAD and BODY tags IE7 / Safari4: Only includes what's between ... Opera 10.10: Keeps HEAD and everything inside it, Keeps contents of BODY The behavior of IE7 and Safari are ideal, but different browsers are doing this differently. Since I'm loading a predetermined HTML document I think I'm going to use the regEx to grab what I want and insert it into a DOM element - unless someone has other suggestions.

  • Building an array out of values from another array

    - by George
    This is a follow up from a question of mine that was just answered concerning parsing numbers in an array. I have an array, data[], with numbers that I'd like to use in a calculation and then put the resulting values into another array. So say data[0] = 100. I'd like to find a percentage using the calculatin, (data[0]/dataSum*100).toFixed(2) where dataSum is the sum of all the numbers in data[]. I've tried: dataPercentage = []; for (var i=0; i < data.length; i++) { data[i] = parseFloat(data[i]); dataSum += data[i]; // looping through data[i] and setting it equal to dataPercentage. dataPercentage[] = (data[i]/dataSum*100).toFixed(2); // thought maybe I was overriding dataPercentage everytime I looped? dataPercentage[] += (data[i]/dataSum*100).toFixed(2); } I also tried just setting dataPercentage = [(data/dataSum*100).toFixed(2)], but I think this creates a nested array, which I don't think is what I need.

  • .net printing multiple reports in one document (architecture question)

    - by LawsonM
    I understand how to print a single document via the PrintDocument class. However, I want to print multiple reports in one document. Each "report" will consist of charts, tables, etc. I want to have two reports per page. I've studied the few examples I can find on how to combine multiple documents into one; however, they always seem to work by creating a collection of objects (e.g. customer or order) that are then iterated over and drawn in the OnPrintPage method. My problem and hence the "architecture" question is that I don't want to cache the objects required to produce the report since they are very large and memory intensive. I'd simply like the resulting "report". One thought I had was to print the report to a metafile, cache that instead in a "MultiplePrintDocument" class and then position those images appropriately two to a page in the OnPrintPage method. I think this would be a lot more efficient and scalable in my case. But I'm not a professional programmer and can't figure out if I'm barking up the wrong tree here. I think the Graphics.BeginContainer and Graphics.Save methods might be relevant, but can't figure out how to implement or if there is a better way. Any pointers would be greatly appreciated.

  • Programatically adding,changing and removing controls bound to model objects (MVVM)

    - by Ittai
    I have the following scenario and I'm trying to decide how it can and should be implemented in silverlight and c# via MVVM. Scenario: I have the following objects in my scenario: MyModel, MyModelControl, MyView and MyViewModel. MyModelcontrol is a custom UserControl of mine and the rest I think are pretty much self explanatory. MyViewModel is a Subscriber of a message which hands it a Collection<MyModel> newCol and let's mark curCol as the current Collection<MyModel> that MyViewModel holds. I then want to programatically add MyModelControl controls for each MyModel instance which belongs to newCol and not to curCol. I also want to bind the MyModelControl instance to the corresponding MyModel instance. In a similar manner I want to remove the controls which don't belong now to the collection and I want to update a property for those which belong to both. I do not want to remove all controls which belong to curCol and then add all controls for newCol as the creation of MyModelControl is "expensive". I'd appreciate help with how this should be implemented in SL as I'm new to it and to the MVVM pattern. Comments regarding the design would also be welcomed. B.T.W This will run on Windows Phone 7 so I think there are some limitations on versions, if this is an issue please comment and I'll verify which versions exactly I can use on the phone.

  • What collection object is appropriate for fixed ordering of values?

    - by makerofthings7
    Scenario: I am tracking several performance counters and have a CounterDescription[] correlate to DataSnapshot[]... where CounterDescription[n] describes the data loaded within DataSnapshot[n]. I want to expose an easy to use API within C# that will allow for the easy and efficient expansion of the arrays. For example CounterDescription[0] = Humidity; DataSnapshot[0] = .9; CounterDescription[1] = Temp; DataSnapshot[1] = 63; My upload object is defined like this: Note how my intent is to correlate many Datasnapshots with a dattime reference, and using the offset of the data to refer to its meaning. This was determined to be the most efficient way to store the data on the back-end, and has now reflected itself into the following structure: public class myDataObject { [DataMember] public SortedDictionary<DateTime, float[]> Pages { get; set; } /// <summary> /// An array that identifies what each position in the array is supposed to be /// </summary> [DataMember] public CounterDescription[] Counters { get; set; } } I will need to expand each of these arrays (float[] and CounterDescription[] ), but whatever data already exists must stay in that relative offset. Which .NET objects support this? I think Array[] , LinkedList<t>, and List<t> Are able to keep the data fixed in the right locations. What do you think?

  • Understanding C++ pointers (when they point to a pointer)

    - by Stephano
    I think I understand references and pointers pretty well. Here is what I (think I) know: int i = 5; //i is a primitive type, the value is 5, i do not know the address. int *ptr; //a pointer to an int. i have no way if knowing the value yet. ptr = &i; //now i have an address for the value of i (called ptr) *ptr = 10; //go get the value stored at ptr and change it to 10 Please feel free to comment or correct these statements. Now I'm trying to make the jump to arrays of pointers. Here is what I do not know: char **char_ptrs = new char *[50]; Node **node_ptrs = new Node *[50]; My understanding is that I have 2 arrays of pointers, one set of pointers to chars and one to nodes. So if I wanted to set the values, I would do something like this: char_ptrs[0] = new char[20]; node_ptrs[0] = new Node; Now I have a pointer, in the 0 position of my array, in each respective array. Again, feel free to comment here if I'm confused. So, what does the ** operator do? Likewise, what is putting a single * next to the instantiation doing (*[50])? (what is that called exactly, instantiation?)

  • Why is Log4Net not creating log file in production?

    - by uriDium
    I am using VS2005, a website project, a web deployment project and Log4Net. I can use logging when I am developing locally. I can see the log files and everything is fine. When I build my website, (using the web deployment project), I use the deploy as a single DLL option. When I then check the locations of where my log files should be I cannot see any files. Is there a way to troubleshoot this. I don't think adding the debug value to the App Settings will help because I don't have a console because it is a website. EDIT I don't want the 150 rep to go to waste so one last time. I compared the internal trace from my dev environment to the trace from the production. My dev environment trace shows the call the Xml Configurator where the production one does not. I have code in the global.asax on application_start() method. I put debug code in there and it is getting called in dev but not in production. I think this is where the web deployment project is causing some issues. Does the global.asax get compiled into the single DLL? When I do a build in the deployment directory I see a global.compiled file. Must this go into the bin folder in production? Or is the global.asax code in the single DLL? Having both in the bin folder or the just the DLL didn't change anything.

  • UDP packets are dropped when its size is less than 12 byte in a certain PC. how do i figure it out the reason?

    - by waan
    Hi. i've stuck in a problem that is never heard about before. i'm making an online game which uses UDP packets in a certain character action. after i developed the udp module, it seems to work fine. though most of our team members have no problem, but a man, who is my boss, told me something is wrong for that module. i have investigated the problem, and finally i found the fact that... on his PC, if udp packet size is less than 12, the packet is never have been delivered to the other host. the following is some additional information: 1~11 bytes udp packets are dropped, 12 bytes and over 12 bytes packets are OK. O/S: Microsoft Windows Vista Business NIC: Attansic L1 Gigabit Ethernet 10/100/1000Base-T Controller WSASendTo returns TRUE. loopback udp packet works fine. how do you think of this problem? and what do you think... what causes this problem? what should i do for the next step for the cause? PS. i don't want to padding which makes length of all the packets up to 12 bytes.

  • What is a good use case for static import of methods?

    - by Miserable Variable
    Just got a review comment that my static import of the method was not a good idea. The static import was of a method from a DA class, which has mostly static methods. So in middle of the business logic I had a da activity that apparently seemed to belong to the current class: import static some.package.DA.*; class BusinessObject { void someMethod() { .... save(this); } } The reviewer was not keen that I change the code and I didn't but I do kind of agree with him. One reason given for not static-importing was it was confusing where the method was defined, it wasn't in the current class and not in any superclass so it too some time to identify its definition (the web based review system does not have clickable links like IDE :-) I don't really think this matters, static-imports are still quite new and soon we will all get used to locating them. But the other reason, the one I agree with, is that an unqualified method call seems to belong to current object and should not jump contexts. But if it really did belong, it would make sense to extend that super class. So, when does it make sense to static import methods? When have you done it? Did/do you like the way the unqualified calls look? EDIT: The popular opinion seems to be that static-import methods if nobody is going to confuse them as methods of the current class. For example methods from java.lang.Math and java.awt.Color. But if abs and getAlpha are not ambiguous I don't see why readEmployee is. As in lot of programming choices, I think this too is a personal preference thing. Thanks for your response guys, I am closing the question.

  • How can I make hundreds of simultaneously running processes communicate with a database through one

    - by Olfan
    Long speech short: How can I make hundreds of simultaneously running processes communicate with a database through one or few permanent sessions? The whole story: I once built a number crunching engine that handles vast amounts of large data files by forking off one child after another giving each a small number of files to work on. File locking, progress monitoring and result propagation happen in an Oracle database which all (sub-)processes access at various times using an application-specific module which encapsulates DBI. This worked well at first, but now with higher volumes of input data, the number of database sessions (one per child, and they can be very short-lived) constantly being opened and closed is becoming an issue. I now want to centralise database access so that there are only one or few fixed database sessions which handle all database access for all the (sub-)processes. The presence of the database abstraction module should make the changes easy because the function calls in the worker instances can stay the same. My problem is that I cannot think of a suitable way to enhance said module in order to establish communication between all the processes and the database connector(s). I thought of message queueing, but couldn't come up with a way of connecting a large herd of requestors with one or few database connectors in a way so that bidirectional communication is possible (for collecting the query result). An asynchronous approach could help here in that all requests are written to the same queue and the database connector servicing the request will "call back" to submit the result. But my mind fails me in generating an image clear enough so that I can paint into code. Threading instead of forking might have given me an easier start, but this would now require massive changes to the code base that I'm not prepared to do to a live system. The more I think of it, the more the base idea looks like a pre-forked web server to me only that it doesn't serve web pages but database queries. Any ideas on what to dig into, and where? Sample (pseudo) code to inspire me, links to possibly related articles, ready solutions on CPAN maybe?

  • Apache crashes, probably because of this piece of php code. Can you have a look?

    - by Munim
    I am working on the development of a web based application on codeigniter. I wrote this function to get the timezone data for any city or address. function gettimezone($address) { $_url = 'http://api.local.yahoo.com/MapsService/V1/geocode'; $_url .= sprintf('?appid=%s&location=%s',"phpclasses",rawurlencode($address)); $_result = false; if($_result = file_get_contents($_url)) { preg_match('!<Latitude>(.*)</Latitude><Longitude>(.*)</Longitude>!U', $_result, $_match); $lng = $_match[2]; $lat = $_match[1]; $url = "http://ws.geonames.org/timezone?lat={$lat}&lng={$lng}"; $timedata = file_get_contents($url); $sxml = simplexml_load_string($timedata); return $sxml->timezone; } else return false; } I am working on Windows 7 and xampp 1.7 (php 5.2.8). Is there any possible scenario where this piece of code would crash Apache? The application runs fine almost everytime, but I think running this piece of code when there is no internet connectivity or very poor internet connectivity (thereby no access to either of the webservices I have used) brings down the server. Something like this happened a few times and I think it was due to loss of internet connectivity but I am not sure what exactly is going on. [ By the way, feel free to use this piece of code. Makes 2 web service calls so don't use to too often in your application. Consider storing the results in a database.]

  • Just 2 free months to learn or improve my skills

    On the 30 of June I will leave my every day work to start as freelance developer. I'd like to set a period of 2 months apart to improve my dev skills. At work I code in C# and during my spare time I enjoyed building Ruby on Rails web applications and creating some Arduino prototypes. I'm something more than junior but I don't feel really a senior developer because I never had a big corporate project built and designed by me with help of other juniors (although I don't think this is really a good definiton of a "senior", It helps describing my feelings). Using a scale from 0 (ignorant) to 10 (proficient like a "samurai") the list below describes my skills that I would like to improve with just 2 months. I've already bought some nice and updated books on all the subjects hereunder: The order doesn't matter C = 1 C# & .Net = 6 Arduino & Processing = 2 Ruby = 5 Rails = 5 HTML/XHTML/CSS = 9 Javascript = 6 Objective-C/iPhone dev = 2 Python = 4 Django = 4 Desing Patterns = 3 Algorythms = 3 Git = 5 I haven't included SQL or Databases in general nor Networking because I spent 10 years working in the past with them and I feel pretty solid for now. As an aside, I've made up some interest in Redis, Node.js, HTML5 reading about them on the web. After two months, since I have to pay my bills, I could go searching for some new job. If learning and developing were really good maybe I could also invest on something I gave birth during them. Can You give me some piece of advice on which you think It's better to improve or develop a learning project on (something like a "summer of code" thing)? The all point Is to see my weaknesses and work on them.

  • Android Facebook RequestListener

    - by Marcus King
    I'm new to Java, but have been a .NET developer for years now and I am a bit confused about the point of the RequestListener object as I can't retrieve the results of my asynchronous calls on the UI thread from what I can tell. My research has told me I should not use singletons or the application context object for getting and storing data. I could use sqlLite, but the data I need is too transient to bother. I would like to know how to have the asyncfacebookrunner object report back it's responses to the UI thread so I can proceed to make decisions between my own api and the objects returned to me from the facebook calls I am making in the async calls. Am I missing something? I can't seem to find a way to get data out. I can pass a Bundle in, but I'm not too sure how to get data out. I would think I would pass it an Intent object to retrieve, but I am not seeing it. I think my eyes are crossed from lack of sleep at this point. Any help here?

  • Sending a password securely using gwt and app engine?

    - by user246114
    Hi, I set up session handling on a google app project. This is supposed to allow my users to login and maintain state across pages. I just dumped it into the default greeting service to try it out: public class GreetingServiceImpl extends RemoteServiceServlet implements GreetingService { public void sessionTest(String username) { HttpSession session = getThreadLocalRequest().getSession(false); session.setAttribute("username", username); } } then attempting to pull it out in my landing project.jsp page: <% String username = null; HttpSession mysession = request.getSession(false); if (mysession.getAttribute("username") != null) { username = (String)mysession.getAttribute("username"); } else { username = "(not logged in yet)"; } <p>You are: <%= username %> </p> %> It works, but I don't know how to send the data in sessionTest() securely. If I were sending the user's password in there too, it would be in the clear. This would be ok (I think) if I was using https, but google app engine does not allow you to use https under custom domains (like www.mysite.com), they have to be under the (mysite.appspot.com) domain. I'm kind of stuck here - how do we send passwords securely? If I was using php, I think I could use digest authentication (I'm not too experienced here) - can we do something like that with gwt + gae? Thanks

  • Why aren't variables declared in "try" in scope in "catch" or "finally"?

    - by Jon Schneider
    In C# and in Java (and possibly other languages as well), variables declared in a "try" block are not in scope in the corresponding "catch" or "finally" blocks. For example, the following code does not compile: try { String s = "test"; // (more code...) } catch { Console.Out.WriteLine(s); //Java fans: think "System.out.println" here instead } In this code, a compile-time error occurs on the reference to s in the catch block, because s is only in scope in the try block. (In Java, the compile error is "s cannot be resolved"; in C#, it's "The name 's' does not exist in the current context".) The general solution to this issue seems to be to instead declare variables just before the try block, instead of within the try block: String s; try { s = "test"; // (more code...) } catch { Console.Out.WriteLine(s); //Java fans: think "System.out.println" here instead } However, at least to me, (1) this feels like a clunky solution, and (2) it results in the variables having a larger scope than the programmer intended (the entire remainder of the method, instead of only in the context of the try-catch-finally). My question is, what were/are the rationale(s) behind this language design decision (in Java, in C#, and/or in any other applicable languages)?

  • HTML columns or rows for form layout?

    - by Valera
    I'm building a bunch of forms that have labels and corresponding fields (input element or more complex elements). Labels go on the left, fields go on the right. Labels in a given form should all be a specific width so that the fields all line up vertically. There are two ways (maybe more?) of achieving this: Rows: Float each label and each field left. Put each label and field in a field-row div/container. Set label width to some specific number. With this approach labels on different forms will have different widths, because they'll depend on the width of the text in the longest label. Columns: Put all labels in one div/container that's floated left, put all fields in another floated left container with padding-left set. This way the labels and even the label container don't need to have their widths set, because the column layout and the padding-left will uniformly take care of vertically lining up all the fields. So approach #2 seems to be easier to implement (because the widths don't need to be set all the time), but I think it's also less object oriented, because a label and a field that goes with that label are not grouped together, as they are in approach #1. Also, if building forms dynamically, approach #2 doesn't work as well with functions like addRow(label, field), since it would have to know about the label and the field containers, instead of just creating/adding one field-row element. Which approach do you think is better? Is there another, better approach than these two?
