• What to see in India as a developer and student

  - by lasseespeholt

  Hi, I'm planning a trip to India around July-August. And I want to hear Indian developers or developers traveled to India if there are something interesting to see in India (around Bombay) for developers in general. Maybe a conference etc. I have looked at http://www.conferencealerts.com/computing.htm I have studied computer science in a year now but have been a spare time and independent developer for some years now. Furthermore, I have tried finding summer courses but that is properly too late now and computer science summer courses is hard to find in India. Best regards, Lasse Espeholt

• Trying to make my leaflet map work on internet explorer

  - by user1270657

  I have been tearing my hair out of late trying to get my web map working on internet explorer. It's working flawlessly on every other major browser but none of the content will load in IE. Anyone out there who's good at browser testing that could help out? I know the leaflet javascript api, which I'm using for this project, supports IE in theory. In practice this isn't working out too well... Link to a live version of the web map: https://mywebspace.wisc.edu/axler/SLRE_Deep_Map/index2.html Let me know if there is anything else I could add that would help in deciphering this problem... Thanks!

• Performance implications of finalizers on JVM

  - by Alexey Romanov

  According to this post, in .Net, Finalizers are actually even worse than that. Besides that they run late (which is indeed a serious problem for many kinds of resources), they are also less powerful because they can only perform a subset of the operations allowed in a destructor (e.g., a finalizer cannot reliably use other objects, whereas a destructor can), and even when writing in that subset finalizers are extremely difficult to write correctly. And collecting finalizable objects is expensive: Each finalizable object, and the potentially huge graph of objects reachable from it, is promoted to the next GC generation, which makes it more expensive to collect by some large multiple. Does this also apply to JVMs in general and to HotSpot in particular?

• How do I handle editing of custom types in a C# datagridview?

  - by Ian Hopkinson

  I have a datagridview in which one column contains a custom class, which I have set using: dgvPeriods.Columns[1].ValueType = typeof(ExDateTime); It is rigged up to display correctly by handling the CellFormatting event, but I'm unsure what event to handle for cell editing. In the absence of doing anything I get a FormatException as the datagridview tries to convert String to ExDateTime as I try to move focus out of the edited cell. I tried adding type conversion to my ExDateTime custom class: public static implicit operator ExDateTime(string b) { return new ExDateTime(b); } But this this didn't work. I also tried handling the DataError event, but this seems to fire too late. The datagridview is not databound.

• Xcode 3.1.2 locks up when loading C++ project...?

  - by Stabledog

  I have a project which builds correctly from the command line. On one of my Macs (10.5) running Xcode 3.1.2, I can load it and build it in the Xcode IDE. On my other Mac (same configuration of software), Xcode sometimes loads the project, but always locks up with a spinning beach ball at some point before the build is done. Sometimes this occurs as the project is loaded, sometimes late in the build. I've tried doing a 'clean' on the project, I've tried pulling in the source code fresh from source control. So far, no luck -- I have to kill Xcode and in effect, cannot develop on this particular Mac. I've uninstalled and reinstalled Xcode. Any clues?

• Add code before initialization of units in Delphi

  - by Alan Clark

  Is there a place where I can add code that will be executed before unit initialization? The reason I want to do this is I need to change the DecimalSeparator, this has to be done before the initialization of some units. I have put it in the project source, before Application.Initialize but it is too late by then. As I see it the only choice I have is to put it in the initialization of the unit that needs the DecimalSeparator to be changed, is this the case? Thanks in advance for any advice.

• Designing a Chart that expands as more data is entered in Excel

  - by Matt Ridge

  I have a worksheet that pulls data from another, it is designed to only show late jobs, and it works perfectly. I have it where it is broken down into quarters, and it gathers all this data and does everything I want. Except this one last bit... I want to have it where it shows charts, if there is data in said area the chart would self populate, otherwise it would be blank. If more data is entered into the range expand the chart accordingly. Attached is a simplified workbook with what it does, and what I'd like to see it do. I don't even know if this is possible... I thought if I wrote a script to make it so that the data changes with each addition it may fix my problem, but I'm not sure if that is the best way in this situation. https://dl.dropbox.com/u/3327208/Excel/Charts.xlsx

• How can I most accurately calculate the execution time of an ASP.NET page while also displaying it o

  - by henningst

  I want to calculate the execution time of my ASP.NET pages and display it on the page. Currently I'm calculating the execution time using a System.Diagnostics.Stopwatch and then store the value in a log database. The stopwatch is started in OnInit and stopped in OnPreRenderComplete. This seems to be working quite fine, and it's giving a similar execution time as the one shown in the page trace. The problem now is that I'm not able to display the execution time on the page because the stopwatch is stopped too late in the life cycle. What is the best way to do this?

• Rails 2.3.5 table populated by fixtures at end of test run rather than at start

  - by rlandster

  I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

• Flow Based Programming

  - by Software Monkey

  I have been doing a little reading on Flow Based Programming over the last few days. There is a wiki which provides further detail. And wikipedia has a good overview on it too. My first thought was, "Great another proponent of lego-land pretend programming" - a concept harking back to the late 80's. But, as I read more, I must admit I have become intrigued. Have you used FBP for a real project? What is your opinion of FBP? Does FBP have a future? In some senses, it seems like the holy grail of reuse that our industry has pursued since the advent of procedural languages.

• Show facebook status stream of a dedicated person on a website

  - by Pascal

  Hi all, I've been stomping at this all day :( I want to display a status feed of both twitter and facebook on my website. For twitter, this is not a problem, as my account is public, I can easily get the feed. Facebook however, is a whole different story! I can't seem to find an easy way to just get my last status updates and display it on my website. The code I currently have, needs authentication of the visitor, and I don't want that! This is my current code: $facebook = new Facebook($api_key, $secret); $stream = $facebook->api_client->fql_query("SELECT message,source,time FROM status WHERE uid = $user_id LIMIT 6"); I've seen several possible solutions, including the RSS feed, but as Facebook keeps changing the way their site works, none of the previous methods I've seen (including those from as late as januari) currently work! Is there anybody who can provide me with a currently working solution to this (simple?) problem?

• what do i need to do now that I want to take programming hobby to next level ?

  - by hohog

  i've always wanted to make games but did not start actively learning programming by myself until 1st year of university. i kept going throughout university learning new languages, showing off things i had made, while neglecting my major in Biology. Anyways, i've ended up with an Economics degree, with a portfolio of SaaS and web apps i had created so i could eat during my final year. So far, I'm getting a few interviews here and there in web programming positions. When I get a logic pretest, I fail miserably. or job requires comp sci degree. I mean I can easily design and code an entire app which I emphasize through my portfolio.... but i dont know why I am so slow at logic puzzles on prescreening interview... So what should I do now ? get certificates in languages ? go back to school and learn CS ? is it too late to get into windows programming jobs than web programming ?

• StackOverflow WordPress Plugin: Sidebar Widget [closed]

  - by Fernando

  I used the idea from "StackOverflow badge to show in your blog" from here to develop a small WordPress plugin to show your SO reputation and badges on your WordPress weblog sidebar. It's awfully lacking some graphic design, style, color, etc. I also thought of adding the user avatar, and images for the different badges. But it's working so far, and it's pretty late and I have to get some sleep. But I'll add the stuff I mentioned tomorrow. That was quite an interesting PHP challenge. Hope someone finds it as usefull as me (already showing it off on my blog :P ). If you're interested: Download it here

• Calling this[int index] via reflection

  - by tkutter

  I try to implement a reflection-based late-bound library to Microsoft Office. The properties and methods of the Offce COM objects are called the following way: Type type = Type.GetTypeFromProgID("Word.Application"); object comObject = Activator.CreateInstance(type); type.InvokeMember(<METHOD NAME>, <BINDING FLAGS>, null, comObject, new object[] { <PARAMS>}); InvokeMember is the only possible way because Type.GetMethod / GetProperty works improperly with the COM objects. Methods and properties can be called using InvokeMember but now I have to solve the following problem: Method in the office-interop wrapper: Excel.Workbooks wb = excel.Workbooks; Excel.Workbook firstWb = wb[0]; respectively foreach(Excel.Workbook w in excel.Workbooks) // doSmth. How can I call the this[int index] operator of Excel.Workbooks via reflection?

• Proguard shrinks too much

  - by vRallev

  Since ADT 17 you can find in the gen folder a BuildConfig class with a DEBUG constant. I often use this constant in my code, since ADT changes the value automatically when you export the application. However with Proguard this doesn't work anymore. E.g. I have following snippet: if (!BuildConfig.DEBUG) { ACRA.init(this); } Proguard notices, that DEBUG is true, so it removes this snippet completely and shrinks the app. After that ADT changes DEBUG constant, but this is too late. The only solution I know is to create my own DEBUG constant and to change it manually again. But I really like the functionality of ADT. Do you know a better solution? Thanks in advance.

• Listen to HTML/CSS events of web page

  - by David Metcalfe

  I'm looking for a way to listen for an event in the HTML/CSS of a webpage. Basically, a website I use at work lists queues and appointments, which flag as yellow/red based on the amount of time late on taking said appointment. Other than this visual aide, there is no alert of any kind, which is a failing point if one is juggling multiple windows and doesn't notice. What I would like to do is put together a simple way to watch for the tag ID or perhaps the flag hex color, and then alert me in a way of my choosing. The work environment is on OS X, so I presume I'm looking at an Objective-C centric solution unless Applescript is capable of doing this. Any help would be greatly appreciated.

• Warning that users of the function must handle

  I am looking for a way to set warning that the user will have to respond. In a sense I would like to use late exception mechanize that occur after the function already finished executing.and returned the wanted value. SomeObject Foo(int input) { SomeObject result; // do something. oh, we need to warn the user. return result; } void Main() { SomeObject object; object = Foo(1); // after copy consturctor is done I would like an exception to be thrown } EDIT: The title to users of the function

• MSAccess Change Date Value Before Validation

  - by sisdog

  In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them. What event can I use? I've tried: LostFocus & BeforeUpdate: too late (validation fires before event) Dirty & OnChange: too early (they haven't left the cell yet) Or is there a way to turn off the native validation rule that is checking for date formats?

• How to protect against GHC7 compiled programs taking all memory?

  - by Petr Pudlák

  When playing with various algorithms in Haskell it often happens to me that I create a program with a memory leak, as it often happens with lazy evaluation. The program taking all the memory isn't really fun, I often have difficulty killing it if I realize it too late. When using GHC6 I simply had export GHCRTS='-M384m' in my .bashrc. But in GHC7 they added a security measure that unless a program is compiled with -rtsopts, it simply fails when it is given any RTS option either on a command line argument or in GHCRTS. Unfortunately, almost no Haskell programs are compiled with this flag, so setting this variable makes everything to fail (as I discovered in After upgrading to GHC7, all programs suddenly fail saying "Most RTS options are disabled. Link with -rtsopts to enable them."). Any ideas how to make any use of GHCRTS with GHC7, or another convenient way how to prevent my programs taking all memory?

• C++0x implementation guesstimates?

  - by dsimcha

  The C++0x standard is on its way to being complete. Until now, I've dabbled in C++, but avoided learning it thoroughly because it seems like it's missing a lot of modern features that I've been spoiled by in other languages. However, I'd be very interested in C++0x, which addresses a lot of my complaints. Any guesstimates, after the standard is ratified, as to how long it will take for major compiler vendors to provide reasonably complete, production-quality implementations? Will it happen soon enough to reverse the decline in C++'s popularity, or is it too little, too late? Do you believe that C++0x will become "the C++" within a few years, or do you believe that most people will stick to the earlier standard in practice and C++0x will be somewhat of a bastard stepchild, kind of like C99?

• SVN: How can I update an existing repository from an exported copy ?

  - by user206705

  Late one afternoon, I did an export of my project repository, and took home my work on my USB key. I've added many changes to the exported project, and now, having returned to the workplace, I want to update the repository with the project that I've now got. To complicate matters, I've made updates to the project in both the main trunk and a branch - and I'd like to update the repository to reflect all those changes. I'm new to SVN and have been relying on tortoise SVN, but I'm a bit lost now. Would I be best to delete the repository and recreate it from the copies/branches I now have? thanks

• problem with generating PDF and session_start()

  - by gillian

  Hi All, I've been using PDF class produced by R&OS successfully in a number of recent developments. I'd like to use it in a page that performs a database query before generating a PDF (it's basically a summary of the session, so I'm using session_id() as part of the query) All is fine if I run this in Firefox - not fine in IE. I think the loading of session_start() is doing something with headers that's upsetting IE as it appears unable to load the page (comment off session_start and the page loads fine). I'm getting a little concerned as, on further investigation, it appears that R&OS is not supported ... bad newbie learning experience and I really don't want to have to try adopt another class system this late in the day. Have you any thoughts as to what I could try next? Thankx G

• replace asp.net Response.Output with my own content

  - by WebDude

  I am trying to intercept a asp.net web request and based on a lookup replace the page thats going to be rendered to the client. example: is a request for "/about-us" comes to my web server, i will first see if i have a version of this in the database, otherwise i will revert to flat files. The version i will retrieve from the database will be a .aspx page that has to be rendered and containt web controls and inline serverside script. What is the best way to go about this? I have tried overriding the CreateHtmlTextWriter method but this seems too late in the process as the TextWriter passed to this method is already instantiated. I have also tried to Implement my own PageHandlerFactory but this seems to create an instance of Page of which i cannot seem to override its internal setting of the Response.Output stream. Amd i barking up the wrong tree here? what is the best approach to take here?

• Best way to utilise an include file which just includes an array in PHP

  - by alex

  Kohana's config files look like this.. here is an example of a database config file (simplified) return array( 'dbhost' => 'localhost', 'user' => 'Tom_Jones' ); I've also got a CMS which wants the connection details. Whilst the CMS uses a different user (with more rights), I'd like to know the best way to include this file and get the data out of it (so as to not repeat myself for hostname and dbname). I haven't thought up of any elegant solutions yet and have not yet dug around Kohana to see how it does it. It's late Friday here so it's probably really obvious to everyone except me. UPDATE My apologies, I forgot to include that this is using Kohana 3!
