• Launch Apple's Stocks app, with a particular stock selected

  - by Vincent Gable

  I would like to launch Apple's Stocks app to show information for a particular stock, on a non-jailbroken phone. I'm not interesting in how to get a quote or graph a stock myself, just opening Stocks.app. I was hoping that the Stocks app would have a custom URL format, so opening a URL like stocks://AAPL would do the trick. But I haven't found anything documenting such a scheme, and suspect it doesn't exist. Any other ideas, or is it impossible to integrate with the native Stocks app?

• Radio buttons: Replacing the stock round ones with built in android buttons

  - by Aaron Kapitsk

  Hi all, how do I create a group of radio buttons where the buttons look like nice stock android buttons? This is what I have found so far: * The look of radio button can be replaced with 4 drawables. * There is an example of ^^ on the web. This does not work for me. So I have figured out two bad choices: A) Use stock buttons -do the radio logic in java. //Gross B) Render the buttons to drawables set them at runtime //Blah Any ideas are very appreciated. (This is my first question here. Hope it is well formulated.)

• E-Business Suite Technology Stack Roadmap (April 2010) Now Available

  - by Steven Chan

  Keeping up with our E-Business Suite technology stack roadmap can be challenging.  Regular readers of this blog know that we certify new combinations and versions of Oracle products with the E-Business Suite every few weeks.  We also update our certification plans and roadmap as new third-party products like Microsoft Office 2010 and Firefox are announced or released.  Complicating matters further, various Oracle products leave Premier Support or are superceded by more-recent versions.This constant state of change means that any static representation of our roadmap is really a snapshot in time, and a snapshot that might begin to yellow and fade fairly quickly.  With that caveat in mind, here's this month's snapshot that I presented at the OAUG/Collaborate 2010 conference in Las Vegas last week:EBS Technology Stack Roadmap (April 2010)

• clear explanation sought: throw() and stack unwinding

  - by Jerry Gagelman

  I'm not a programmer but have learned a lot watching others. I am writing wrapper classes to simplify things with a really technical API that I'm working with. Its routines return error codes, and I have a function that converts those to strings: static const char* LibErrString(int errno); For uniformity I decided to have member of my classes throw an exception when an error is encountered. I created a class: struct MyExcept : public std::exception { const char* errstr_; const char* what() const throw() {return errstr_;} MyExcept(const char* errstr) : errstr_(errstr) {} }; Then, in one of my classes: class Foo { public: void bar() { int err = SomeAPIRoutine(...); if (err != SUCCESS) throw MyExcept(LibErrString(err)); // otherwise... } }; The whole thing works perfectly: if SomeAPIRoutine returns an error, a try-catch block around the call to Foo::bar catches a standard exception with the correct error string in what(). Then I wanted the member to give more information: void Foo::bar() { char adieu[128]; int err = SomeAPIRoutine(...); if (err != SUCCESS) { std::strcpy(adieu,"In Foo::bar... "); std::strcat(adieu,LibErrString(err)); throw MyExcept((const char*)adieu); } // otherwise... } However, when SomeAPIRoutine returns an error, the what() string returned by the exception contains only garbage. It occurred to me that the problem could be due to adieu going out of scope once the throw is called. I changed the code by moving adieu out of the member definition and making it an attribute of the class Foo. After this, the whole thing worked perfectly: a try-call block around a call to Foo::bar that catches an exception has the correct (expanded) string in what(). Finally, my question: what exactly is popped off the stack (in sequence) when the exception is thrown in the if-block when the stack "unwinds?" As I mentioned above, I'm a mathematician, not a programmer. I could use a really lucid explanation of what goes onto the stack (in sequence) when this C++ gets converted into running machine code.

• Best development architecture for a small team of programmers ( WAMP Stack )

  - by Tio

  Hi all.. I'm in the first month of work in a new company.. and after I met the two programmer's and asked how things are organized in terms of projects inside the company, they simply shrug their shoulders, and said that nothing is organized.. I think my jaw hit the ground that same time.. ( I know some, of you think I should quit, but I'm on a privileged position, I'm the most experienced there, so there's room for me to grow inside the company, and I'm taking the high road ).. So I talked to the IT guy, and one of the programmers, and maybe this week I'm going to get a server all to myself to start organizing things. I've used various architectures in my previous work experiences, on one I was developing in a server on the network ( no source control of course ).. another experience I had was developing in my local computer, with no server on the network, just source control. And at home, I have a mix of the two, everything I code is on a server on the network, and I have those folders under source control, and I also have a no-ip account configured on that server so I can access it everywhere and I can show the clients anything. For me I think this last solution ( the one I have at home ) is the best: Network server with WAMP stack. The server as a public IP so we can access it by domain name. And use subdomains for each project. Everybody works directly on the network server. I think the problem arises, when two or more people want to work on the same project, in this case the only way to do this is by using source control and local repositories, this is great, but I think this turns development a lot more complicated. In the example I gave, to make a change to the code, I would simply need to open the file in my favorite editor, make the change, alter the database, check in the changes into source control and presto all done. Using local repositories, I would have to get the latest version, run the scripts on the local database to update it, alter the file, alter the database, check in the changes to the network server, update the database on the network server, see if everything is running well on the network server, and presto all done, to me this seems overcomplicated for a change on a simple php page. I could share the database for the local development and for the network server, that sure would help. Maybe the best way to do this is just simply: Network server with WAMP stack ( test server so to speak ), public server accessible trough the web. LAMP stack on every developer computer ( minus the database ) We develop locally, test, then check in the changes into the server test and presto. What do you think? Maybe I should start doing this at home.. Thanks and best regards... Edit: I'm sorry I made a mistake and switched WAMP with LAMP, sorry about that..

• Preloading Winforms using a Stack and Hidden Form

  - by msarchet

  I am currently working on a project where we have a couple very control heavy user controls that are being used inside a MDI Controller. This is a Line of Business app and it is very data driven. The problem that we were facing was the aforementioned controls would load very very slowly, we dipped our toes into the waters of multi-threading for the control loading but that was not a solution for a plethora of reasons. Our solution to increasing the performance of the controls ended up being to 'pre-load' the forms onto a hidden window, create a stack of the existing forms, and pop off of the stack as the user requested a form. Now the current issue that I'm seeing that will arise as we push this 'fix' out to our testers, and the ultimately our users is this: Currently the 'hidden' window that contains the preloaded forms is visible in task manager, and can be shut down thus causing all of the controls to be lost. Then you have to create them on the fly losing the performance increase. Secondly, when the user uses up the stack we lose the performance increase (current solution to this is discussed below). For the first problem, is there a way to hide this window from task manager, perhaps by creating a parent form that encapsulates both the main form for the program and the hidden form? Our current solution to the second problem is to have an inactivity timer that when it fires checks the stacks for the forms, and loads a new form onto the stack if it isn't full. However this still has the potential of causing a hang in the UI while it creates the forms. A possible solutions for this would be to put 'used' forms back onto the stack, but I feel like there may be a better way. EDIT: For control design clarification From the comments I have realized there is a lack of clarity on what exactly the control is doing. Here is a detailed explanation of one of the controls. I have defined for this control loading time as the time it takes from when a user performs an action that would open a control, until the time a control is accessible to be edited. The control is for entering Prescriptions for a patient in the system, it has about 5 tabbed groups with a total of about 180 controls. The user selects to open a new Prescription control from inside the main program, this control is loaded into the MDI Child area of the Main Form (which is a DevExpress Ribbon Control). From the time the user clicks New (or loads an existing record) until the control is visible. The list of actions that happens in the program is this: The stack is checked for the existence of a control. If the control exists it is popped off of the stack. The control is rendered on screen. This is what takes 2 seconds The control then is populated with a blank object, or with existing data. The control is ready to use. The average percentage of loading time, across about 10 different machines, with different hardware the control rendering takes about 85 - 95 percent of the control loading time. Without using the stack the control takes about 2 seconds to load, with the stack it takes about .8 seconds, this second time is acceptable. I have looked at Henry's link and I had previously already implemented the applicable suggestions. Again I re-iterate my question as What is the best method to move controls to and from the stack with as little UI interruption as possible?

• Fields of class, are they stored in the stack or heap?

  - by Mirek

  I saw a question yesterday which raised (for me) another question. Please look at the following code: public class Class1 { int A; //as I uderstand, int is value type and therefore lives in the stack } class Class2 { Run() { Class1 instance1 = new Class1(); instance1.A = 10; //it points to value type, but isnt this reference (on heap)? } } Or while creating the instance of Class1, its field types are created on the heap as well? But then I do not understand when it would really be on the stack as almost always you need to create an instance of object in order to use it fields.

• What is the relationship between recursion functions and memory stack?

  - by Eslam

  is there's a direct relationship between recursive functions and the memory stack, for more explanation consider that code: public static int triangle(int n) { System.out.println(“Entering: n = ” + n); if (n == 1) { System.out.println(“Returning 1”); return 1; } else { int temp = n + triangle(n - 1); System.out.println(“Returning“ + temp); return temp; } }? in this example where will the values 2,3,4,5 be stored until the function returns ? note that they will be returned in LIFO(LastInFirstOut) is these a special case of recursion that deals with the memory stack or they always goes together?

• IA-32: Pushing a byte onto a stack isn't possible on Pentium, why?

  - by Tim Green

  Hi, I've come to learn that you cannot push a byte directly onto the Intel Pentium's stack, can anyone explain this to me please? The reason that I've been given is because the esp register is word-addressable (or, that is the assumption in our model) and it must be an "even address". I would have assumed decrementing the value of some 32-bit binary number wouldn't mess with the alignment of the register, but apparently I don't understand enough. I have tried some NASM tests and come up that if I declare a variable (bite db 123) and push it on to the stack, esp is decremented by 4 (indicating that it pushed 32-bits?). But, "push byte bite" (sorry for my choice of variable names) will result in a kind error: test.asm:10: error: Unsupported non-32-bit ELF relocation Any words of wisdom would be greatly appreciated during this troubled time. I am first year undergraduate so sorry for my naivety in any of this. Tim

• What stack would you use for a new web Java project if you started today?

  - by Joelio

  If you were to start a brand new java project today with the following requirements: high scale (20k + users) you want to use something that is fairly mature (not changing dramatically) & wont be dead technology in 3 years you want something very productive (no server restarts in dev, save the code and its automatically compiled and deployed), productivity and time to market are key. some amount of ajax on front end no scripting language, jruby, groovy, php etc , has to be java has to support i8n What stack would you use & Why? (when I say stack, I mean, everything soup to nuts, so app server, mvc framework, bean framework, ORM framework, javascript framework etc...)

• Accessing Yahoo realtime stock quotes

  - by DVK

  There's a fairly easy way of retrieving 15-minute delayed quotes off of Yahoo! Finance web site ("quotes.csv" API). However, so far I was unable to find any info on how to access real-time quotes. The hang-ups with real-time quotes are: Only available to logged-in user No API Non-obvious how to scrape the info - I'm somewhat convinced they are placed on the page by some weird Ajax call. So I was wondering if anyone had managed to develop a publically available solution to retrieve real-time quotes for a stock from Yahoo! Finance. Notes: Implementation language/framework need is flexible but Perl or Excel is highly preferred. Assume that security is not an issue - I'm willing to supply yahoo userid and pasword, even in cleartext. I'm not 100% hung up on Yahoo - they are merely the only provider of free realtime stock quotes I'm familiar with. if the same thing can be done with Google Finance, I'd be just as happy. This is for a personal project, so scalability/fault tolerance/etc... are not important. I'm looking for a "do the whole retrieval" library ideally, but if I'm pointed to partial solutions (e.g. how to retrieve info from Yahoo's user-logged-in pages; how to scrape realtime quotes from Yahoo's page) I can fill in the blanks. I saw Finance::YahooQuote but it does not seem to allow you to supply log-in information and appears to use the lagging quotes.csv API Thanks!

• 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?

• Indexed view deadlocking

  - by Dave Ballantyne

  Deadlocks can be a really tricky thing to track down the root cause of.  There are lots of articles on the subject of tracking down deadlocks, but seldom do I find that in a production system that the cause is as straightforward.  That being said,  deadlocks are always caused by process A needs a resource that process B has locked and process B has a resource that process A needs.  There may be a longer chain of processes involved, but that is the basic premise. Here is one such (much simplified) scenario that was at first non-obvious to its cause: The system has two tables,  Products and Stock.  The Products table holds the description and prices of a product whilst Stock records the current stock level. USE tempdb GO CREATE TABLE Product ( ProductID INTEGER IDENTITY PRIMARY KEY, ProductName VARCHAR(255) NOT NULL, Price MONEY NOT NULL ) GO CREATE TABLE Stock ( ProductId INTEGER PRIMARY KEY, StockLevel INTEGER NOT NULL ) GO INSERT INTO Product SELECT TOP(1000) CAST(NEWID() AS VARCHAR(255)), ABS(CAST(CAST(NEWID() AS VARBINARY(255)) AS INTEGER))%100 FROM sys.columns a CROSS JOIN sys.columns b GO INSERT INTO Stock SELECT ProductID,ABS(CAST(CAST(NEWID() AS VARBINARY(255)) AS INTEGER))%100 FROM Product There is a single stored procedure of GetStock: Create Procedure GetStock as SELECT Product.ProductID,Product.ProductName FROM dbo.Product join dbo.Stock on Stock.ProductId = Product.ProductID where Stock.StockLevel <> 0 Analysis of the system showed that this procedure was causing a performance overhead and as reads of this data was many times more than writes,  an indexed view was created to lower the overhead. CREATE VIEW vwActiveStock With schemabinding AS SELECT Product.ProductID,Product.ProductName FROM dbo.Product join dbo.Stock on Stock.ProductId = Product.ProductID where Stock.StockLevel <> 0 go CREATE UNIQUE CLUSTERED INDEX PKvwActiveStock on vwActiveStock(ProductID) This worked perfectly, performance was improved, the team name was cheered to the rafters and beers all round.  Then, after a while, something else happened… The system updating the data changed,  The update pattern of both the Stock update and the Product update used to be: BEGIN TRAN UPDATE... COMMIT BEGIN TRAN UPDATE... COMMIT BEGIN TRAN UPDATE... COMMIT It changed to: BEGIN TRAN UPDATE... UPDATE... UPDATE... COMMIT Nothing that would raise an eyebrow in even the closest of code reviews.  But after this change we saw deadlocks occuring. You can reproduce this by opening two sessions. In session 1 begin transaction Update Product set ProductName ='Test' where ProductID = 998 Then in session 2 begin transaction Update Stock set Stocklevel = 5 where ProductID = 999 Update Stock set Stocklevel = 5 where ProductID = 998 Hop back to session 1 and.. Update Product set ProductName ='Test' where ProductID = 999 Looking at the deadlock graphs we could see the contention was between two processes, one updating stock and the other updating product, but we knew that all the processes do to the tables is update them.  Period.  There are separate processes that handle the update of stock and product and never the twain shall meet, no reason why one should be requiring data from the other.  Then it struck us,  AH the indexed view. Naturally, when you make an update to any table involved in a indexed view, the view has to be updated.  When this happens, the data in all the tables have to be read, so that explains our deadlocks.  The data from stock is read when you update product and vice-versa. The fix, once you understand the problem fully, is pretty simple, the apps did not guarantee the order in which data was updated.  Luckily it was a relatively simple fix to order the updates and deadlocks went away.  Note, that there is still a *slight* risk of a deadlock occurring, if both a stock update and product update occur at *exactly* the same time.

• performing simple stack overflow on Mac os 10.6

  - by REALFREE

  I'm trying to learn about stack base overflow and write a simple code to exploit stack. But somehow it doesn't work at all but showing only Abort trap on my machine (mac os leopard) I guess Mac os treats overflow differently, it won't allow me to overwrite memory through c code. for example, strcpy(buffer, input) // lets say char buffer[6] but input is 7 bytes on Linux machine, this code successfully overwrite next stack, but prevented on mac os (Abort trap) Anyone know how to perform a simple stack-base overflow on mac machine?

• Where my memory is alloced, Stack or Heap, Can I find it at Run-time?

  - by AKN

  I know that memory alloced using new, gets its space in heap, and so we need to delete it before program ends, to avoid memory leak. Let's look at this program... Case 1: char *MyData = new char[20]; _tcscpy(MyData,"Value"); . . . delete[] MyData; MyData = NULL; Case 2: char *MyData = new char[20]; MyData = "Value"; . . . delete[] MyData; MyData = NULL; In case 2, instead of allocating value to the heap memory, it is pointing to a string literal. Now when we do a delete it would crash, AS EXPECTED, since it is not trying to delete a heap memory. Is there a way to know where the pointer is pointing to heap or stack? By this the programmer Will not try to delete any stack memory He can investigate why does this ponter, that was pointing to a heap memory initially, is made to refer local literals? What happened to the heap memory in the middle? Is it being made to point by another pointer and delete elsewhere and all that?

• LAMP Stack Versioning -- Is there a website or version tracker source to help suggest the right versions of each part of a platform stack?

  - by Chris Adragna

  Taken singly, it's easy to research versions and compatibility. Version information is readily available on each single part of a platform stack, such as MySQL. You can find out the latest version, stable version, and sometimes even the percentage of people adopting it by version (personally, I like seeing numbers on adoption rates). However, when trying to find the best possible mix of versions, I have a harder time. For example, "if you're using MySQL 5.5, you'll need PHP version XX or higher." It gets even more difficult to mitigate when you throw higher level platforms into the mix such as Drupal, Joomla, etc. I do consider "wizard" like installers to be beneficial, such as the Bitnami installers. However, I always wonder if those solutions cater more to the least common denominator -- be all to many -- and as such, I think I'd be better to install things on my own. Such solutions do seem kind of slow to adopt new versions, slower than necessary, I suspect. Is there a website or tool that consolidates versioning data in order to help a webmaster choose which versions to deploy or which upgrades to install, in consideration of all the other parts of the stack?

• Podcasting vs Stack Overflow vs Geekswithblogs

  - by MarkPearl

  For a few years now I have been looking for effective ways to be involved in the “community”. While there are a few community programming events in my area (Johannesberg), there isn’t too much face to face stuff – which has caused me to turn to the internet. My internet attempts have been varied – at first I took the passive approach of listening to tech podcasts. This was great for a while, but soon the content became semi-repetitive and a little boring. It seemed that the podcasts I was listening to all went round the same themes and speakers and while I am still a keen listener to several tech podcasts – it didn’t quench my thirst. So I began to be a bit more active – starting with stack overflow – where I would scan the site for questions that were in the realm of my ability to answer. It worked for a while but soon it began to be discouraging – there seems to be so many people that know so much more than me and are quicker at typing that I felt fairly ineffective. So while I still use Stack Overflow when I am in a pickle and need some help – it feels more like me taking from the community than giving anything. Which brought me to Geeks with blogs. Till I found GWB I hadn’t felt like I was an active part of a community. I had blogged before on Blogspot and Wordpress but hadn’t felt associated to the community. Now when I get a comment from someone on one of my GWB posts either thanking me or adding a bit more or correcting me, it makes me feel like I am contributing to a community. So well done GWB. Thanks for making a spot that makes me feel at home!

• Caching in the .NET Stack: Inside-Out

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/06/28/caching-in-the-.net-stack-inside-out.aspxI'm delighted to have my first course published on Pluralsight - Caching in the .NET Stack: Inside-out.   It's a pretty comprehensive look at caching in .NET solutions. The first half covers using local, remote and persistent cache stores inside the solution, including the .NET MemoryCache, NCache Express, AppFabric Caching, memcached, Azure Table Storage and local disk stores. The second half covers caching outside the solution in HTTP clients and proxies, and how to set up ASP.NET WebForms, MVC, Web API and WCF projects to use HTTP validation and expiration caching.   The course takes a hands-on approach, starting with a distributed solution that has no caching, analysing key points which can benefit from caching, and adding different types of cache. At the end of the course I run through a set of before and after performance tests, stressing the solution under load. Without caching and with 60 concurrent users the page response time maxes out at 18 seconds - with caching that falls to 2 seconds, so it's a huge improvement from very little effort. I’d be glad to hear feedback if you watch the course, especially if it’s as positive as my editor’s.

• How to implement a stack of game states in C++

  - by Lisandro Vaccaro

  I'm new to C++ and as a college proyect I'm building a 2D platformer with some classmates, I recently read that it's a good idea to have a stack of gamestates instead of a single global variable with the game state (which is what I have now) but I'm not sure how to do it. Currently this is my implementation: class GameState { public: virtual ~GameState(){}; virtual void handle_events() = 0; virtual void logic() = 0; virtual void render() = 0; }; class Menu : public GameState { public: Menu(); ~Menu(); void handle_events(); void logic(); void render(); }; Then I have a global variable of type GameState: GameState *currentState = NULL; And in my Main I define the currentState and call it's methods: int main(){ currentState = new Menu(); currentState.handle_events(); } How can I implement a stack or something similar to go from that to something like this: int main(){ statesStack.push(new Menu()); statesStack.getTop().handle_events(); }
