• source of historical stock data

  - by rmeador

  I'm trying to make a stock market simulator (perhaps eventually growing into a predicting AI), but I'm having trouble finding data to use. I'm looking for a (hopefully free) source of historical stock market data. Ideally, it would be a very fine-grained (second or minute interval) data set with price and volume of every symbol on NASDAQ and NYSE (and perhaps others if I get adventurous). Does anyone know of a source for such info? I found this question which indicates Yahoo offers historical data in CSV format, but I've been unable to find out how to get it in a cursory examination of the site linked. I also don't like the idea of downloading the data piecemeal in CSV files... I imagine Yahoo would get upset and shut me off after the first few thousand requests. I also discovered another question that made me think I'd hit the jackpot, but unfortunately that OpenTick site seems to have closed its doors... too bad, since I think they were exactly what I wanted. I'd also be able to use data that's just open/close price and volume of every symbol every day, but I'd prefer all the data if I can get it. Any other suggestions?

• Installing Sphinx on App Engine - possible?

  - by Pekka

  Following up on my last year's question on documentation, I now want to get started and try out Python-based Sphinx for putting together the developer documentation for a PHP CMS I've been working on. Instead of setting up Python locally on my workstation, I would like to run it on a publicly accessible web server from the start. All the web hosting packages I have access to run on the LAMP stack, and I'm reluctant to buy Python-based hosting. I am very interested in the Google App Engine, the free quotas they provide will do for me a hundred times over, and even if not, their pricing looks very reasonable. Now I have zero knowledge of Python - getting Sphinx to work would be my first contact with it - and very little time. As far as I understand, the platform and python libraries the App Engine provides are very compatible to a standard Python library but not identical. So my question is: Can Sphinx run on App Engine at all? Is installing Sphinx on the App Engine as straightforward as if I would install it on top of a normal Python installation? Or will the App Engine's environment require tweaking of the source code that I can't perform in reasonable time with my current level of Python? Should I be installing Sphinx on a local server and a "normal" Python stack instead first? Does anybody know any helpful How-to's, tutorials or other resources for this?

• Mix Audio tracks with offset in SOX

  - by Laramie

  From ASP.Net, I am using FFMPEG to convert flv files on a Flash Media Server to wavs that I need to mix into a single MP3 file. I originally attempted this entirely with FFMPEG but eventually gave up on the mixing step because I don't believe it it possible to combine audio only tracks into a single result file. I would love to be wrong. I am now using FFMPEG to access the FLV files and extract the audio track to wav so that SOX can mix them. The problem is that I must offset one of the audio tracks by a few seconds so that they are synchronized. Each file is one half of a conversation between a student and a teacher. For example teacher.wav might need to begin 3.3 seconds after student.wav. I can only figure out how to mix the files with SOX where both tracks begin at the same time. My best attempt at this point is: ffmpeg -y -i rtmp://server/appName/instance/student.flv -ac 1 student.wav ffmpeg -y -i rtmp://server/appName/instance/teacher.flv -ac 1 teacher.wav sox -m student.wav teacher.wav combined.mp3 splice 3.3 These tools (FFMEG/SoX) were chosen based on my best research, but are not required. Any working solution would allow an ASP.Net service to input the two FMS flvs and create a combined MP3 using open-source or free tools.

• Java library class to handle scheduled execution of "callbacks"?

  - by Hanno Fietz

  My program has a component - dubbed the Scheduler - that lets other components register points in time at which they want to be called back. This should work much like the Unix cron service, i. e. you tell the Scheduler "notify me at ten minutes past every full hour". I realize there are no real callbacks in Java. Here's my approach, is there a library which already does this stuff? Feel free to suggest improvements, too. Register call to Scheduler passes: a time specification containing hour, minute, second, year month, dom, dow, where each item may be unspecified, meaning "execute it every hour / minute etc." (just like crontabs) an object containing data that will tell the calling object what to do when it is notified by the Scheduler. The Scheduler does not process this data, just stores it and passes it back upon notification. a reference to the calling object Upon startup, or after a new registration request, the Scheduler starts with a Calendar object of the current system time and checks if there are any entries in the database that match this point in time. If there are, they are executed and the process starts over. If there aren't, the time in the Calendar object is incremented by one second and the entreis are rechecked. This repeats until there is one entry or more that match(es). (Discrete Event Simulation) The Scheduler will then remember that timestamp, sleep and wake every second to check if it is already there. If it happens to wake up and the time has already passed, it starts over, likewise if the time has come and the jobs have been executed. Edit: Thanks for pointing me to Quartz. I'm looking for something much smaller, however.

• Log 2 N generic comparison tree

  - by Morano88

  Hey! I'm working on an algorithm for Redundant Binary Representation (RBR) where every two bits represent a digit. I designed the comparator that takes 4 bits and gives out 2 bits. I want to make the comparison in log 2 n so If I have X and Y .. I compare every 2 bits of X with every 2 bits of Y. This is smooth if the number of bits of X or Y equals n where (n = 2^X) i.e n = 2,4,8,16,32,... etc. Like this : However, If my input let us say is 6 or 10 .. then it becomes not smooth and I have to take into account some odd situations like this : I have a shallow experience in algorithms .. is there a generic way to do it .. so at the end I get only 2 bits no matter what the input is ? I just need hints or pseudo-code. If my question is not appropriate here .. so feel free to flag it or tell me to remove it. I'm using VHDL by the way!

• MySQL INJECTION Solution...

  - by Val

  I have been bothered for so long by the MySQL injections and was thinking of a way to eliminate this problem all together. I have came up with something below hope that many people will find this useful. The only Draw back I can think of this is the partial search: Jo =returns "John" by using the like %% statement. Here is a php solution: <?php function safeQ(){ $search= array('delete','select');//and every keyword... $replace= array(base64_encode('delete'),base64_encode('select')); foreach($_REQUEST as $k=>$v){ str_replace($search, $replace, $v); } } foo(); function html($str){ $search= array(base64_encode('delete'),base64_encode('select')); $replace= array('delete','select');//and every keyword... str_replace($search, $replace, $str); } //example 1 ... ... $result = mysql_fetch_array($query); echo html($result[0]['field_name']); //example 2 $select = 'SELECT * FROM safeQ($_GET['query']) '; //example 3 $insert = 'INSERT INTO .... value(safeQ($_GET['query']))'; ?> I know, I know that you still could inject using 1=1 or any other type of injections... but this I think could solve half of your problem so the right mysql query is executed. So my question is if anyone can find any draw backs on this then please feel free to comment here. PLEASE GIVE AN ANSWER only if you think that this is a very useful solution and no major drawbacks are found OR you think is a bad idea all together...

• Problems Using memset and memcpy

  - by user306557

  So I am trying to create a Memory Management System. In order to do this I have a set amount of space (allocated by malloc) and then I have a function myMalloc which will essentially return a pointer to the space allocated. Since we will then try and free it, we are trying to set a header of the allocated space to be the size of the allocated space, using memset. memset(memPtr,sizeBytes,sizeof(int)); We then need to be able to read this so we can see the size of it. We are attempting to do this by using memcpy and getting the first sizeof(int) bytes into a variable. For testing purposes we are just trying to do memset and then immediately get the size back. I've included the entire method below so that you can see all declarations. Any help would be greatly appreciated! Thanks! void* FirstFit::memMalloc(int sizeBytes){ node* listPtr = freelist; void* memPtr; // Cycle through each node in freelist while(listPtr != NULL) { if(listPtr->size >= sizeBytes) { // We found our space // This is where the new memory allocation begins memPtr = listPtr->head; memset(memPtr,sizeBytes,sizeof(int)); void *size; memcpy(size, memPtr, sizeof(memPtr)); // Now let's shrink freelist listPtr->size = listPtr->size - sizeBytes; int *temp = (int*)listPtr->head + (sizeBytes*sizeof(int)); listPtr->head = (int*) temp; return memPtr; } listPtr = listPtr->next; }

• howto distinguish composition and self-typing use-cases

  - by ayvango

  Scala has two instruments for expressing object composition: original self-type concept and well known trivial composition. I'm curios what situations I should use which in. There are obvious differences in their applicability. Self-type requires you to use traits. Object composition allows you to change extensions on run-time with var declaration. Leaving technical details behind I can figure two indicators to help with classification of use cases. If some object used as combinator for a complex structure such as tree or just have several similar typed parts (1 car to 4 wheels relation) than it should use composition. There is extreme opposite use case. Lets assume one trait become too big to clearly observe it and it got split. It is quite natural that you should use self-types for this case. That rules are not absolute. You may do extra work to convert code between this techniques. e.g. you may replace 4 wheels composition with self-typing over Product4. You may use Cake[T <: MyType] {part : MyType} instead of Cake { this : MyType => } for cake pattern dependencies. But both cases seem counterintuitive and give you extra work. There are plenty of boundary use cases although. One-to-one relations is very hard to decide with. Is there any simple rule to decide what kind of technique is preferable? self-type makes you classes abstract, composition makes your code verbose. self-type gives your problems with blending namespaces and also gives you extra typing for free (you got not just a cocktail of two elements but gasoline-motor oil cocktail known as a petrol bomb). How can I choose between them? What hints are there? Update: Let us discuss the following example: Adapter pattern. What benefits it has with both selt-typing and composition approaches?

• Do I need Response.End() in ASP.Net 2.0

  - by Hamish Grubijan

  Hi, I am just starting with ASP.Net. I copied a ex-co-worker's code (from .Net 1.1 era) and it has a Response.End(); in case of an error. There is also a: catch (Exception ex) { Response.Write(ex.Message); Response.End(); } at the end of Page_Load(object sender, System.EventArgs e) which always appends "Thread was aborted." or something like that at the end. I suspect that this worked differently before, or the error conditions were not tested very well. Anyhow, I was able to stop using Response.End(); in case when I do not like the GET parameters, and use return; instead. It seemed to do the right think in a simple case. Is this Ok in general? There are some problems with the code I copied, but I do not want to do a rewrite; I just want to get it running first and find wrinkles later. The Response.End(); caused a mental block for me, however, so I want to figure it out. I want to keep the catch all clause just in case, at least for now. I could also end the method with: catch (System.Threading.ThreadAbortException) { Response.End(); } catch (Exception ex) { Response.Write(ex.Message); Response.End(); } but that just seems extremely stupid, once you think about all of the exceptions being generated. Please give me a few words of wisdom. Feel free to ask if something is not clear. Thanks! P.S. Ex-coworker was not fired and is a good coder - one more reason to reuse his example.

• Can I use manifests to consume a COM server without specifying its version?

  - by sharptooth

  Two of our programs use the same COM server (also made by us) with the same class ids. Each program when installing copies the COM server files into its folder and regsvr32s the COM server. The problem is how to install the COM server so that the user can install either one or both of our programs into different folders in any order and likely of different versions. Clearly it's impossible without changing the class ids and that's lots of hassle with configurations. Ideally we would like to use manifests for that and go without regsvr32. The problem is every time I read about reg-free COM (for example, here) there's the version attribute in the assemblyIdentity. The version number should change every nightly build and I totally don't like the idea of (automatically) adjusting it. I understand why specifying dependency on a specific version is good, but it's completely useless in our scenarion. Is there a way to write manifests for both the COM server and the consumer so that they don't specify versions and just work with whatever version of the file happens to be in the folder? Also is there a way to restrict the search to the same folder as the consumer?

• Which CSS editor can give nested formatting like this in one shot automatically?

  - by jitendra

  Which free (offline) CSS tool can give formatting like this in one shot automatically? using any keyboard shortcut of from any command of IDE example This (it can be any type of formatting) #proceed_form ol, #demo_form ol { list-style:none; margin:0; padding:0} #proceed_form ol li, #demo_form ol li { padding:2px 0; margin:0; line-height:normal; height:18px} #proceed_form ol li label, #demo_form ol li label { display:inline-block; width:195px;} into like this #proceed_form ol, #demo_form ol { list-style: none; margin: 0; padding: 0 } #proceed_form ol li, #demo_form ol li { padding: 2px 0; margin: 0; line-height: normal; height: 18px } #proceed_form ol li label, #demo_form ol li label { display: inline-block; width: 195px; } Can we achieve this type of formatting in Dreamweaver? or it not possible in dreamweaver then in any other tool?

• Java many to many association map

  - by Raphael Jolivet

  Hi, I have to classes, ClassA and ClassB and a "many to many" AssociationClass. I want to use a structure to hold the associations between A and B such as I can know, for each instance of A or B, which are their counterparts. I thought of using a Hashmap, with pair keys: Hasmap<Pair<ClassA, ClassB>, AssociationClass> associations; This way, I can add and remove an association between two instances of ClassA and ClassB, and I can query a relation for two given instances. However, I miss the feature of getting all associations defined for a given instance of ClassA or ClassB. I could do it by brute force and loop over all keys of the map to search for associations between a given instance, but this is inefficient and not elegant. Do you know of any data structure / free library that enables this ? I don't want to reinvent the wheel. Thanks in advance for your help, Raphael NB: This is not a "database" question. These objects are pure POJO used for live computation, I don't need persistence stuff.

• Javascript Rich Display Component/Methodology

  - by Laramie

  quick back story-- I am working on ASP.Net based template editor that lets authors create text templates using Javascript inserted placeholder tags that will be filled in with dynamic text when the templates are used to display the final results. For example the author might create a template like The word [%12#add] was generated dynamically. The application would eventually replace the tag with a dynamic word down the road (though it's not specifically relevant to this post) The word foo was generated dynmamically. Depending on the circumstances, the template may be created in a text input, textarea or a modified version of the Ajax Control Toolkit HTML Editor. There might be 40 or more of these editable elements on the page, so using lots of stripped down or modified HTML editors would probably bog the page down too much. The problem is that the tags such as [%12#add] are displayed inline with the user text and the result is confusing and aesthetically gross. The goal is parse the contens of the source element and when a tags such as [%12#add] are encountered, display something prettier and less cryptic to the user such as a stylable element or image wherever tags such as [%12#add] occur. The application still needs the template text with the tags on postback. So the user might see The word tag placeholder was generated dynamically. but the original template would still be the value of the text input box The word [%12#add] was generated dynamically. It seems HTML editors like the ACT version and FckEditor accomplish this by rendering their output in an IFrame, but rather than kill myself trying to roll a lighter specialized version myself, I thought I'd ask if anyone knows of an existing free component or approach that has already tackled this. With good reason, I don't think S.O. allows HTML formatting, but the bold "tag placeholder" above would ideally be something like tag placeholder.

• When is someone else's code I use from the internet "mine"?

  - by robault

  I'm building a library from methods that I've found on the internet. Some are free to use or modify with no requirements, others say that if I leave a comment in the code it's okay to use, others say when I use the code I have to attribute the use of someone's code in my application (in the credits for my app I guess). What I've been doing is reorganizing classes, renaming methods, adding descriptions (code comments), renaming the parameters and names inside the methods to something meaningful, optimizing loops if applicable, changing return types, adding try/catch/throw blocks, adding parameter checks and cleaning up resources in the methods. For example; I didn't come up with the algorithm for blurring a Bitmap but I've taken the basic example of iterating through the pixels and turned it into a decent library method (applying the aforementioned modifications). I understand how to go about building it now myself but I didn't actually hit the keystrokes to make it and I couldn't have come up with it before learning from their example. What about code people get in answers on Stackoverflow or examples from Codeproject? At what point can I drop their requirements because at n% their code became mine? FWIW I intend on using the libraries to create products that I will sell.

• IMAP protocol support in different email servers

  - by raticulin

  Having to interact with several different email servers via IMAP (using javamail), I have found that there is a very different level of support for IMAP features among them. The lack of support of some features has resulted in more developing time, more complicated code to deal with different support, worse perforamance due to not being able to SEARCH etc. So I would like to get some info on other servers and what level of support they provide. So far I have dealt with Lotus Domino and Novell GroupWise (and to a lesser extend Exchange 2003 and 2007). I am particularly interested in most used one in unix/linux (Courier, Cyrus, Dovecot, UW IMAP) and also Zimbra, but feel free to add any you know. Also welcomed info about online services like gmail. Features that I consider (comment if you are interested in others and I'll add them. Custom flags Searching Custom flags Searching arbitrary headers Partial fetching Proxy authentication And what I have found so far (correct if I am wrong anywhere): Lotus Domino Custom flags yes Searching Custom flags yes Searching arbitrary headers yes Partial fetching ? Proxy authentication sort of, you can give some user permissions to access other users mailboxes and he will see them under his '\Other Users' folder Novell GroupWise Custom flags No Searching Custom flags No Searching arbitrary headers No Partial fetching ? Proxy authentication yes, you can use what is called a Trusted Application

• Nested namespaces, correct static library design issues

  - by PeterK

  Hello all, I'm currently in the process of developing a fairly large static library which will be used by some tools when it's finished. Now since this project is somewhat larger than anything i've been involved in so far, I realized its time to think of a good structure for the project. Using namespaces is one of those logical steps. My current approach is to divide the library into parts (which are not standalone, but their purpose calls for such a separation). I have a 'core' part which now just holds some very common typedefs and constants (used by many different parts of the library). Other parts are for example some 'utils' (hash etc.), file i/o and so on. Each of these parts has its own namespace. I have nearly finished the 'utils' part and realized that my approach probably is not the best. The problem (if we want to call it so) is that in the 'utils' namespace i need something from the 'core' namespace which results in including the core header files and many using directives. So i began to think that this probably is not a good thing and should be changed somehow. My first idea is to use nested namespaces as to have something like core::utils. Since this will require some heavy refactoring i want to ask here first. What do you think? How would you handle this? Or more generally: How to correctly design a static library in terms of namespaces and code organization? If there are some guidelines or articles about it, please mentoin them too. Thanks. Note: i'm quite sure that there are more good approaches than just one. Feel free to post your ideas, suggestions etc. Since i'm designing this library i want it to be really good. The goal is to make it as clean and FAST as possible. The only problem is that i will have to integrate a LOT of existing code and refactor it, which will really be a painful process (sigh) - thats why good structure is so important)

• How to debug PHP?

  - by NutMotion

  Anyone's been trying himself at object oriented programming ? Most probably every developer I guess:D I for one have never studied OO design patterns thoroughly, and trying to put it all together now does prove at times thrilling, and many times frustrating also. Even more so when trying to do it in : PHP! All-in-all, my boss asked me to add some Database persistence functions to her server, but most of all, she asked me to translate her already working procedural code into a working Object Oriented code. Here I am, still standing on my PHP OO project. I'm (already) fed up with this "file logging only" PHP capability. I believe there must be some (free or not too much expansive) PHP debugging utility ? I've heard about Zend Studio and PHPEd so far, which didn't quite do the trick for whatever reasons. WIRCW("Which I don't Remember Correctly Why" lol) What say yé? on debugging PHP ? Is there a tool that provides a good debug mode? what's more, don't forget I'm not speaking about the classical web Request/response model. Talking about a debugging facility which can enable you to trigger a web service (aka client request) and go into debug mode on the SOAP web service side. Thks for any input.

• Java Client .class File Protection

  - by Zac

  I am in the requirements phase of building a JEE application that will most likely run on a GlassFish/JBoss backend (doesn't matter for now). I know I shouldn't be thinking about architecture at requirements time, but one can't help but start to imagine how the components would all snap together :-) Here are some hard, non-flexible requirements on the client-side: (1) The client application will be a Swing box (2) The client is free to download, but will use a subscription model (thus requiring a login mechanism with server-side authentication/authorization, etc.) (3) Yes, Java is the best platform solution for the problem at hand for reasons outside the scope of this post (4) The client-side .class files need safeguarding against decompiling That last (4th) requirement is the basis of this post. I'm not really worried about someone actually decompiling and getting at my source code: in the end, it's just Swing controls driven by some lightweight business logic. I'm worried about a scenario where someone decompiles my code, modifies it to exploit/attack the server, re-compiles, and fires it up. I've envisioned all sorts of nasty solutions, but didn't know if this was a common problem with a common solution for JEE developers. Any thoughts? Not interested in "code obfuscation" techniques! Thanks for any input!

• Why does this data YYYY-MM-DD regex fail in Java?

  - by ProfessionalAmateur

  Hello StackOverFlow, My first question and Im excited... I've lurked since go-live and love the site, however I apologize for any newbie errors, formatting, etc... I'm attempting to validate the format of a string field that contains a date in Java. We will receive the date in a string, I will validate its format before parsing it into a real Date object. The format being passed in is in the YYYY-MM-DD format. However I'm stuck on one of my tests, if I pass in "1999-12-33" the test will fail (as it should with a day number 33) with this incomplete pattern: ((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-([12][0-9]|3[01]) However as soon as I add the characters in bold below it passes the test (but should not) ((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-(0[1-9]|[1-9]|[12][0-9]|3[01]) *additional note, I know I can change the 0[1-9]|[1-9] into 0?[1-9] but I wanted to break everything down to its most simple format to try and find why this isn't working. Here is the scrap test I've put together to run through all the different date scenarios: import java.util.regex.Matcher; import java.util.regex.Pattern; public class scrapTest { public scrapTest() { } public static void main(String[] args) { scrapTest a = new scrapTest(); boolean flag = a.verfiyDateFormat("1999-12-33"); } private boolean verfiyDateFormat(String dateStr){ Pattern datePattern = Pattern.compile("((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-(0[1-9]|[1-9]|[12][0-9]|3[01])"); Matcher dateMatcher = datePattern.matcher(dateStr); if(!dateMatcher.find()){ System.out.println("Invalid date format!!! -> " + dateStr); return false; } System.out.println("Valid date format."); return true; } } Ive been programming for ~10 years but extremely new to Java, so please feel free to explain anything as elementary as you see fit.

• tipfy for Google App Engine: Is it stable? Can auth/session components of tipfy be used with webapp?

  - by cv12

  I am building a web application on Google App Engine that requires users to register with the application and subsequently authenticate with it and maintain sessions. I don't want to force users to have Google accounts. Also, the target audience for the application is the average non-geek, so I'm not very keen on using OpenID or OAuth. I need something simple like: User registers with an e-mail and password, and then can log back in with those credentials. I understand that this approach does not provide the security benefits of Google or OpenID authentication, but I am prepared to trade foolproof security for end-user convenience and hassle-free experience. I explored Django, but decided that consecutive deprecations from appengine-helper to app-engine-patch to django-nonrel may signal that path may be a bit risky in the long-term. I'd like to use a code base that is likely to be maintained consistently. I also explored standalone session/auth packages like gaeutilities and suas. GAEUtilities looked a bit immature (e.g., the code wasn't pythonic in places, in my opinion) and SUAS did not give me a lot of comfort with the cookie-only sessions. I could be wrong with my assessment of these two, so I would appreciate input on those (or others that may serve my objective). Finally, I recently came across tipfy. It appears to be based on Werkzeug and Alex Martelli spoke highly of it here on stackoverflow. I have two primary questions related to tipfy: As a framework, is it as mature as webapp? Is it stable and likely to be maintained for some time? Since my primary interest is the auth/session components, can those components of the tipfy framework be used with webapp, independent of the broader tipfy framework? If yes, I would appreciate a few pointers to how I could go about doing that.

• How do I create a python module from a fortran program with f2py?

  - by Lars Hellemo

  I am trying to read some smps files with python, and found a fortran implementation, so I thought I would give f2py a shot. The problem is that I have no experience with fortran. I have successfully installed gfortran and f2py on my Linux box and ran the example on thew f2py page, but I have some trouble compiling and running the large program. There are two files, one with a file reader wrapper and one with all the logic. They seem to call each other, but when I compile and link or try f2py, I get errors that they somehow can't find each other: f95 -c FILEWR~1.F f95 -c SMPSREAD.F90 f95 -o smpsread SMPSREAD.o FILEWR~1.o FILEWR~1.o In function `file_wrapper_' FILEWR~1.F(.text+0x3d) undefined reference to `chopen_' usrlibgcci486-linux-gnu4.4.1libgfortranbegin.a(fmain.o) In function `main' (.text+0x27) undefined reference to `MAIN__' collect2 ld returned 1 exit status I also tried changing the name to FILE_WRAPPER.F but that did not help. With f2py I found out I had to include a comment to get it to accept free format, and saved this as a new file and tried: f2py -c -m smpsread smpsread.f90 I get a lot of output and warnings, but the error seems to be this one: getctype: No C-type found in "{'typespec': 'type', 'attrspec': ['allocatable'], 'typename': 'node', 'dimension': [':']}", assuming void. The fortran 90 spms reader can be found here. Any help or suggestions appreciated.

• Word-wrap grid cells in Ext JS

  - by richardtallent

  (This is not a question per se, I'm documenting a solution I found using Ext JS 3.1.0. But, feel free to answer if you know of a better solution!) The Column config for an Ext JS Grid object does not have a native way to allow word-wrapped text, but there is a css property to override the inline CSS of the TD elements created by the grid. Unfortunately, the TD elements contain a DIV element wrapping the content, and that DIV is set to white-space:nowrap by Ext JS's stylesheet, so overriding the TD CSS does no good. I added the following to my main CSS file, a simple fix that appears to not break any grid functionality, but allows any white-space setting I apply to the TD to pass through to the DIV. .x-grid3-cell { /* TD is defaulted to word-wrap. Turn it off so it can be turned on for specific columns. */ white-space:nowrap; } .x-grid3-cell-inner { /* Inherit DIV's white-space from TD parent, since DIV's inline style is not accessible in the column definition. */ white-space:inherit; } YMMV, but it works for me, wanted to get it out there as a solution since I couldn't find a working solution by searching the Interwebs.

• Limit iPhone in-app purchase by user's country

  - by Ryan

  Hello everyone. I'm a product manager who works for a small internet company that is developing an iPhone application for a social network. We monetize by offering limited and premium memberships to users (premium members get additional features not available to limited members). For billing on the web, we use a 3rd-party payment gateway that is nearing retirement, and will be replaced by an in-house solution. The business wants a global launch for our iPhone app using iTunes + in-app purchasing as a payment gateway. The problem with going global using this payment method is that for our web service membership level, available features, and subscription costs are defined by country. For example, in the US premium/limited memberships are available at 5 pricing tiers; in France premium/limited memberships are available at 5 different pricing tiers from the US; and in Chile the service is available for free and all features are available to users. Is it possible then to have the server-side, based on the user's country of registration, control the level of access, features, and payment options for users on the iPhone? I'd also note that since iTunes Connect does not allow variable pricing by currency and country, each "region" would need 5 in app purchase options. I argued for a US-only launch for iPhone using iTunes in app purchase until an in-house payment gateway is available. But you know...
