  • Is it better to comment out unneeded code or delete it?

    - by Matt Connolly
    For web applications under maintenance, assuming you have source control, when you need to remove part of the UI and the associated code, do you delete the code and check in, or do you comment out the old code? Arguments in favor of deleting: cleaner code, can still see deleted code in source control history, no worrying about refactoring code that might be uncommented some day. Arguments in favor of commenting: sometimes you need to add the feature back in and the developer adding it back in may not know to check source control history, sometimes the code represents unique functionality that can be a handy reference, seeing it all in one place can help provide clues to deciphering the active code.

  • Why is autorelease especially dangerous/expensive for iPhone applications?

    - by e.James
    I'm looking for a primary source (or a really good explanation) to back up the claim that the use of autorelease is dangerous or overly expensive when writing software for the iPhone. Several developers make this claim, and I have even heard that Apple does not recommend it, but I have not been able to turn up any concrete sources to back it up. SO references: autorelease-iphone Why does this create a memory leak (iPhone)? Note: I can see, from a conceptual point of view, that autorelease is slightly more expensive than a simple call to release, but I don't think that small penalty is enough to make Apple recommend against it. What's the real story?

  • Direct web URL to PayPal transaction

    - by tags2k
    Having implemented PayPal's Website Payments Standard, I'd like to link to the details view of a transaction from my site's back end - just a simple direct web URL to the PayPal side. I don't know why this is tricky but when I try to get it from being logged in to the PayPal system it seems very obfuscated, in this form: history.paypal.com/uk/cgi-bin/webscr?cmd=_history-details&info=[looks like some kind of GUID]&ptype=4&history_cache=[huge encoded string] I'm guessing it's by design but it's not very helpful if you want a quick way to jump to a transaction's details. I've tried the https://www.paypal.com/vst/id=1234 form (also with co.uk as I am UK-based) recommended on a few sites I saw in my search, but I am told that: The transaction ID in your link is invalid. This happens even when copying the transaction ID directly from PayPal's back-end order listing. Is there a reliable way to directly link to an order / transaction details page in PayPal?

  • jquery ajax vs browser url

    - by danwoods
    Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

  • The best way to separate admin functionality from a public site?

    - by AndrewO
    I'm working on a site that's grown both in terms of user-base and functionality to the point where it's becoming evident that some of the admin tasks should be separate from the public website. I was wondering what the best way to do this would be. For example, the site has a large social component to it, and a public sales interface. But at the same time, there's back office tasks, bulk upload processing, dashboards (with long running queries), and customer relations tools in the admin section that I would like to not be effected by spikes in public traffic (or effect the public-facing response time). The site is running on a fairly standard Rails/MySQL/Linux stack, but I think this is more of an architecture problem than an implementation one: mainly, how does one keep the data and business logic in sync between these different applications? Some strategies that I'm evaluating: 1) Create a slave database of the public facing database on another machine. Extract out all of the model and library code so that it can be shared between the applications. Create new controllers and views for the admin interfaces. I have limited experience with replication and am not even sure that it's supposed to be used this way (most of the time I've seen it, it's been for scaling out the read capabilities of the same application, rather than having multiple different ones). I'm also worried about the potential for latency issues if the slave is not on the same network. 2) Create new more task/department-specific applications and use a message oriented middleware to integrate them. I read Enterprise Integration Patterns awhile back and they seemed to advocate this for distributed systems. (Alternatively, in some cases the basic Rails-style RESTful API functionality might suffice.) But, I have nightmares about data synchronization issues and the massive re-architecting that this would entail. 3) Some mixture of the two. For example, the only public information necessary for some of the back office tasks is a read-only completion time or status. Would it make sense to have that on a completely separate system and send the data to public? Meanwhile, the user/group admin functionality would be run on a separate system sharing the database? The downside is, this seems to keep many of the concerns I have with the first two, especially the re-architecting. I'm sure the answers are going to be highly dependent on a site's specific needs, but I'd love to hear success (or failure) stories.

  • innodb lock wait timeout

    - by shantanuo
    As per the documentation link given below: When a lock wait timeout occurs, the current statement is not executed. The current transaction is not rolled back. (Until MySQL 5.0.13 InnoDB rolled back the entire transaction if a lock wait timeout happened. You can restore this behavior by starting the server with the --innodb_rollback_on_timeout option, available as of MySQL 5.0.32. http://dev.mysql.com/doc/refman/5.0/en/innodb-parameters.html#sysvar_innodb_lock_wait_timeout Does it mean that when a lock wait timeout occurs, it compromises the transactional integrity? "roollback on timeout" was the default behaviour till 5.0.13 and I guess that was the correct way to handle such situations. Does anyone think that this should be the default behaviour and the user should not be asked to add a parameter for a functionality that is taken for granted?

  • Cookie access within a HTTP Class

    - by James Jeffery
    I have a HTTP class that has a Get, and Post, method. It's a simple class I created to encapsulate Post and Get requests so I don't have to repeat the get/post code throughout the application. In C#: class HTTP { private CookieContainer cookieJar; private String userAgent = "..."; public HTTP() { this.cookieJar = new CookieContainer(); } public String get(String url) { // Make get request. Return the JSON } public String post(String url, String postData) { // Make post request. Return the JSON } } I've made the CookieJar a property because I want to preserve the cookie values throughout the session. If the user is logged into Twitter with my application, each request I make (be it get or post) I want to use the cookies so they remain logged in. That's the basics of it anyway. But, I don't want to return a string in all instances. Sometimes I may want the cookie, or a header value, or something else from the request. Ideally I'd like to be able to do this in my code: Cookie cookie = http.get("http://google.com").cookie("g_user"); String g_user = cookie.value; or String source = http.get("http://google.com").body; My question - To do this, would I need to have a Get class, and a Post class, that are included within the HTTP class and are accessible via accessors? Within the Get and Post class I would then have the Cookie method, and the body property, and whatever else is needed. Should I also use an interface, or create a Request class and have Post and Get extend it so that common methods and properties are available to both classes? Or, am I thinking totally wrong?

  • Java app makes screen display unresponsive after 10 minutes of user idle time

    - by Ross
    I've written a Java app that allows users to script mouse/keyboard input (JMacro, link not important, only for the curious). I personally use the application to automate character actions in an online game overnight while I sleep. Unfortunately, I keep coming back to the computer in the morning to find it unresponsive. Upon further testing, I'm finding that my application causes the computer to become unresponsive after about 10 minutes of user idle time (even if the application itself it simulating user activity). I can't seem to pin-point the issue, so I'm hoping somebody else might have a suggestion of where to look or what might be causing the issue. The relevant symptoms and characteristics: Unresponsiveness occurs after user is idle for 10 minutes User can still move the mouse pointer around the screen Everything but the mouse appears frozen... mouse clicks have no effect and no applications update their displays, including the Windows 7 desktop I left the task manager up along the with the app overnight so I could see the last task manager image before the screen freezes... the Java app is at normal CPU/Memory usage and total CPU usage is only ~1% After moving the mouse (in other words, the user comes back from being idle), the screen image starts updating again within 30 minutes (this is very hit and miss... sometimes 10 minutes, sometimes no results after two hours) User can CTRL-ALT-DEL to get to Windows 7's CTRL-ALT-DEL screen (after a 30 second pause). User is still able to move mouse pointer, but clicking any of the button options causes the screen to appear to freeze again On some very rare occasions, the system never freezes, and I come back to it in the morning with full responsiveness The Java app automatically stops input scripting in the middle of the night, so Windows 7 detects "real" idleness and turns the monitors into Standby mode... which they successfully come out of upon manually moving the mouse in the morning when I wake up, even though the desktop display still appears frozen Given the symptoms and characteristics of the issue, it's as if the Java app is causing the desktop display of the logged in user to stop updating, including any running applications. Programming concepts and Java packages used: Multi-threading Standard out and err are rerouted to a javax.swing.JTextArea The application uses a Swing GUI awt.Robot (very heavily used) awt.PointerInfo awt.MouseInfo System Specs: Windows 7 Professional Java 1.6.0 u17 In conclusion, I should stress that I'm not looking for any specific solutions, as I'm not asking a very specific question. I'm just wondering if anybody has run into a similar problem when using the Java libraries that I'm using. I would also gladly appreciate any suggestions for things to try to attempt to further pinpoint what is causing my problem. Thanks! Ross PS, I'll post an update/answer if I manage to stumble across anything else while I continue to debug this.

  • Making form submissions unique using PHP and HTML

    - by canadiancreed
    Hello all I'm currently developing a page where the user fills out a form, and when submitted they are taken to the next page. When on the next page, I want to have it so that if the user went back to the previous page using the back button, or hit refresh, the submission will not be saved into the DB. Now I recall reading somewhere that if you had a way to make each submission unique, this issue is averted, but after screwing around for hours on end, for the life of me I cannot recall how this could be done (using PHP), so long story short has anyone ran into this, and if so, what was your solution?

  • how to copy char * into a string and visa versa

    - by user295030
    If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

  • Basic Android Layout Question

    - by jonhobbs
    Hi, I'm new to android but I've been working my way through the tutoials. Still trying to get my head round layouts in a non-html world and was wondering how to achieve the following.... 1) I'd like to set a tiled background to fill the screen behind the whole activity 2) I'd like to place a graphic and a button underneath it centred in the middle of the screen. 3) When the user clicks the button I'd like to start a new activity and presumably I have to do something to the current activity so the user can use the back button to get back to it. Sorry for the newbie question. Jon

  • What are the correct steps to capture data with uploadify?

    - by Curtis
    Does anyone have a demo of using uploadify with additional fields and saving to database? The site's examples don't explain the process in depth and I am not familiar with jquery. I don't know why but I can't get my head around how too integrate the two. I have the demo working and I have my app which uses traditional php/html forms working. I need to conduct basic form collection with uploadify in the mix. Collect data and check data with feedback and then process into database and post back a confirmation. How do I feed information back to the uploadify form if there is a problem from the upload.php file? How do I access my data in the upload.php file? how do I redirect the upload page to a confirmation page after a succeeful upload?

    Hi there I have a regular dll with the followign fucntion exported. extern "C" __declspec(dllexport) int FindNearestStuff(double _latitude, double _longitude , LocationStruct * locations[]) LocationStruct is very simple struct LocationStruct { long positionIndex; long item; }; I'm tryign to call it from c# using [DllImport("myclever.dll", CharSet = CharSet.None)] private static extern int FindNearestStuff(double _latitude, double _longitude, ref LocationStruct [] locations); Its all cool and funky and i can step into the dll function from the debugger. Inside the dll the LocationStruct array is populated correctly and all is very good. the problem i have is when it returns back from the dll, the LocationStruct array is not coming back with the data - just empty values... what am i missing? cheers Buzz

  • Deciding on a company-wide javascript strategy [on hold]

    - by drogon
    Our company is moving most of its software from thick-client winforms apps to web apps. We are using asp.net mvc on the server side. Most of the developers are brand new to the web and need to become efficient and knowledgeable at writing client-side web code (javascript). We are deciding on a number of things and would appreciate feedback on the following: Angular.js or Backbone.js? Backbone (w/ Underscore) is certainly more light weight, but requires more custom development. Angular seems to be a full-fledged framework, but would require everyone to embrace it and probably a longer learning curve(??). (Note: I know nothing about Angular at this point) Require.js or script includes w/ MVC bundleconfig? Require.js makes development "feel like" c# (importing namespaces). But, integrating the build/minification process can be a pain (especially the configuration). Bundling via mvc requires developers to worry more about which scripts to include but has less overall development friction. Typescript vs Javascript Regardless of frameworks, our developers are going to need to learn the basics. Typescript is more like c# and MAY be easier for c# developers to understand. However, learning TypeScript before javascript may hinder their mastery of javascript at the expense of efficiency.

    Hi everyone, I am writing a simple android application with a class that extends activity, that plays a video from a url on the web. There is a button on top that on click takes the user to a web page. What I want to do is when the user is browsing the web page, if he hits the back button, I want him to come back to the main activity and restart the video. Is there a way to do this? Also, is there a way the video can be resumed from where it left off? Thank you. Chris

  • Single click to activate last tab in windows 7 internet explorer (like FF)

    - by Kirk Hings
    Windows 7 annoyance: the jump lists are fine for hovering over the taskbar items, great go ahead and show me previews of all the open instances and maybe I'll pick the exact one I want. However this works different between IE and FF. Hovering over the FF icon just shows me the single FF window, not any of the tabs I have open. Clicking it means my FF window opens and I'm at the last tab I was on. Great, normal behavior, one click and I'm in. Hovering over the IE icon shows me all the tabs in my single IE window. Ok, but I just want to go back to my last active IE tab. I can't! I am forced to click twice to go back to any IE tab. Sure it's a minor annoyance, but as I'm developing throughout the day I find it more and more annoying. Any ideas to fix so I can just click the IE taskbar icon once and it pulls up the last tab I was on?

  • File IO, Handling CRLF

    - by aCuria
    Hi, i am writing a program that takes a file and splits it up into multiple small files of a user specified size, then join the multiple small files back again. 1) the code must work for c, c++ 2) i am compiling with multiple compilers. I am reading and writing to the files by using the stl functions fread() and fwrite() The problem I am having pertains to CRLF. If the file I am reading from contains CRLF, then I want to retain it when i split and join the files back together. If the file contains LF, then i want to retain LF. Unfortunately, fread() seems to store CRLF as \n (I think), and whatever is written by fwrite() is compiler-dependent. How do i approach this problem? Thanks.

  • Passing Auth to API calls with Web Service References

    - by coffeeaddict
    I am new to web services. The last time I dealt with SOAP was when I created a bunch of wrapper classes that sent requests and received responses back per some response objects/classes I had created. So I had an object to send certain API requests and likewise a set of objects to hold the response back as an object so I could utilize that 3rd party API. Then someone came to me and said why not just use the wsdl and a web service. Ok, so today I went and created a "Service Reference". I see that this is what's called a "Proxy Class". You just instantiate an instance of this and then walla you have access to all the methods from the wsdl. But this leaves me with auth questions. Back when I created my own classes manually, I had a class which exposed properties that I would set then access for things like signature, username, password that got sent along with the Http request that were required by whatever 3rd party API I was using to make API calls. But then with using a Service Reference, how then would I pass this information just like I had done in my custom classes? For instance I'm going to be working with the PayPal API. It requires you to send a signature and a few other pieces of information like username and password. // Determins if API call needs to use a session based URI string requestURI = UseAuthURI == true ? _requestURIAuthBased + aSessionID : _requestURI; byte[] data = XmlUtil.DocumentToBytes(doc); // Create the atual Request instance HttpWebRequest request = CreateWebRequest(requestURI, data.Length); So how do I pass username, password, signature, etc. when using web service references for each method call? Is it as simple as specifying it as a param to the method or do you use the .Credentials and .URL methods of your proxy class object? It seems to me Credentials means windows credentials but I could be wrong. Is it limited to that or can you use that to specify those required header values that PayPal expects with each method call/API request?

  • I need data structure for effective handling with dates

    - by ante.sabo
    What I need is something like Hashtable which I will fill with prices that were actual at desired days. For example: I will put two prices: January 1st: 100USD, March 5th: 89USD. If I search my hashtable for price: hashtable.get(February 14th) I need it to give me back actual price which was entered at Jan. 1st because this is the last actual price. Normal hashtable implementation won't give me back anything, since there is nothing put on that dat. I need to see if there is such implementation which can find quickly object based on range of dates.

  • How to stop an Android Service ONLY when there are no other activities in my app running?

    - by johnrock
    Is there a way I can test if there are any other activities in my app still alive? I am looking to stop a service in an onDestroy method, but only want to do this if there are no other activities from my app still alive on the stack. I have the call stop the service in the main activity's onDestroy() method. This works perfect EXCEPT that if a user launches my app, then launches a few activities in my app, then hits the home screen and RELAUNCHES my app, they will subvert my order and the main activity will now be above other activities of my app. From this state, if they hit the back button and 'back out' of my home screen they will trigger the onDestroy() method and kill the service even though there are other activities open on the stack. I want to avoid this by stopping the service ONLY if I am sure there are no other activities of mine open on the stack. Possible?

  • Why does this script work in the current directory but fail when placed in the path?

    - by kiloseven
    I wish to replace my failing memory with a very small shell script. #!/bin/sh if ! [ –a $1.sav ]; then mv $1 $1.sav cp $1.sav $1 fi nano $1 is intended to save the original version of a script. If the original has been preserved before, it skips the move-and-copy-back (and I use move-and-copy-back to preserve the original timestamp). This works as intended if, after I make it executable with chmod I launch it from within the directory where I am editing, e.g. with ./safe.sh filename However, when I move it into /usr/bin and then I try to run it in a different directory (without the leading ./) it fails with: *-bash: /usr/bin/safe.sh: /bin/sh: bad interpreter: Text file busy* My question is, when I move this script into the path (verified by echo $PATH) why does it then fail? D'oh? Inquiring minds want to know how to make this work.
