• Issue with jQuery ajax post (working with get). error 12031

  - by jul

  hi, UPDATE: I didn't set the response mimetype to 'application/json'. It works now. In the website I'm working on (http://piem.org:8000/) I've got an issue with an ajax post request. Every time the search button is clicked or the google maps 'idle' is triggered I send a request to get some data. While the request works as expected in most cases, it returns an error when I click a result and come back to the search page. (type 'barcelona' in the search box to get the unique restaurant in the db). The server processes the request properly but it seems that the error occurs when the javascript receives it (it returns a "12031" error code). It works properly with FF 3.0.6, IE 8.0 and Chrome 5.0 with GET, and with FF with both POST and GET. Anybody can help? thanks jul

• Is it possible to disable a ScrollViewer from inside the ScrollViewer?

  - by gehho

  From a UserControl, I would like to disable a ScrollViewer which is defined one level higher. My scenario looks something like this: <!-- ... --> <ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled"> <custom:MyUserControl ... /> </ScrollViewer> Now, I would like to disable the ScrollViewer from within MyUserControl. Is this possible? Background: I have defined a custom TabControl style where I added a ScrollViewer for each item's content automatically. However, in one case, I do not want to use that ScrollViewer, but rather make the content size to the available space, whereas in all other cases I do want to use the ScrollViewer. Any ideas? Of course, I could add a ScrollViewer to every tab item manually, except for the one item, but that is not what I want.

• App engine datastore - query on Enum fields.

  - by Gopi

  I am using GAE(Java) with JDO for persistence. I have an entity with a Enum field which is marked as @Persistent and gets saved correctly into the datastore (As observed from the Datastore viewer in Development Console). But when I query these entities putting a filter based on the Enum value, it is always returning me all the entities whatever value I specify for the enum field. I know GAE java supports enums being persisted just like basic datatypes. But does it also allow retrieving/querying based on them? Google search could not point me to any such example code. Details: I have printed the Query just before being executed. So in two cases the query looks like - SELECT FROM com.xxx.yyy.User WHERE role == super ORDER BY key desc RANGE 0,50 SELECT FROM com.xxx.yyy.User WHERE role == admin ORDER BY key desc RANGE 0,50 Both above queries return me all the User entities from datastore in spite of datastore viewer showing some Users are of type 'admin' and some are of type 'super'.

• Is regex too slow? Real life examples where simple non-regex alternative is better

  - by polygenelubricants

  I've seen people here made comments like "regex is too slow!", or "why would you do something so simple using regex!" (and then present a 10+ lines alternative instead), etc. I haven't really used regex in industrial setting, so I'm curious if there are applications where regex is demonstratably just too slow, AND where a simple non-regex alternative exists that performs significantly (maybe even asymptotically!) better. Obviously many highly-specialized string manipulations with sophisticated string algorithms will outperform regex easily, but I'm talking about cases where a simple solution exists and significantly outperforms regex. What counts as simple is subjective, of course, but I think a reasonable standard is that if it uses only String, StringBuilder, etc, then it's probably simple.

• Guessing the time zone from an arbitrary "location" string?

  - by Thomas

  I'm trying to run some statistics over the Stack Overflow data dump, and for that I would like to know the time zone for each user. However, all I have to go on is the completely free-form "location" string. I'll stress that I'm only looking for an approximation of the time zone; of course, in general this is an unsolvable problem. However, many people fill out their country, state and/or city, which should give a pretty good indication. It's okay if it fails for other cases. It doesn't have to be reliable, it doesn't have to be accurate, it doesn't have to cover all bases. I don't want to waste too much time on this, so I'm wondering if there is some code out there that can make a reasonable guess. Any language, platform, API or library goes. Any ideas?

• Firebug not showing Javascript errors for Rails applications

  - by 99miles

  I have a Rails application, and when I have Javascript errors they are not showing in the Firebug console. I have 'Show javascript errors' and 'Show javascript warnings' selected. When I insert javascript errors in a basic html file, the errors show as expected. In the javascript of the Rails app, it only shows errors in rare cases. For example i can insert nonsense like: dfghaefb; and no error is shown in Firebug. But if i insert a space in there Firebug does show the error: dfgh aefb; Any ideas? This is driving me nuts.

• Automation of testing using JUnit

  - by Vijay Selvaraj

  Hi, i am trying to automate manual testing of modules in my project. We are dealing with IBM Websphere Message queue software. We have a trigger component written in core java which when executed polls for availability of message in the configured queue. Its an indefinite while loop that keeps the trigger component running. I have written test cases in JUnit to put message in the queue and now will i be able to start/stop the trigger component on demand? Invoking the trigger component keeps it running and i am not getting the control back to check the expected output. If i start it in thread then the log files to which the trigger component is supposed to update when processing the message is not getting updated. How can i resolve this situation. Your suggestion and directions is highly appreciated. Thanks, -Vijay

• Static analysis of multiple if statements (conditions)

  - by koppernickus

  I have code similar to: if conditionA(x, y, z) then doA() else if conditionB(x, y, z) then doB() ... else if conditionZ(x, y, z) then doZ() else throw ShouldNeverHappenException I would like to validate two things (using static analysis): If all conditions conditionA, conditionB, ..., conditionZ are mutually exclusive (i.e. it is not possible that two or more conditions are true in the same time). All possible cases are covered, i.e. "else throw" statement will never be called. Could you recommend me a tool and/or a way I could (easily) do this? I would appreciate more detailed informations than "use Prolog" or "use Mathematica"... ;-)

• Way to turn on keyboard's caps-lock light without actually turning on caps-lock?

  - by cksubs

  I'm writing a program that uses caps-lock as a toggle switch. It would be nice to set the LED of the key to show that my program is on or off, like the capslock key does naturally. I know that I could just SendInput('Capslock'); or whatever to actually turn caps-lock on and off. But my app is a typing program, and I don't want to have to deal with translating the all-caps keys that turning it on would give me into their lower/upper cases. I might go that route eventually, but not for this version. I would however be interested in just turning on the LED light WITHOUT actually turning on caps-lock. Is there any way to do that? Thank you.

• Skip sanitization for videos in html5lib

  - by pug

  I am using a wmd-editor in django, much like this one in which I am typing. I would like to allow the users to embed videos in it. For that I am using the Markdown video extension here. The problem is that I am also sanitizing user input using html5lib sanitization and it doesn't allow object tags which are required to embed the videos. One solution could be to check the input for urls of well-known video sites and skip the sanitization in those cases. Is there a better solution?

• store everything only once, smarter

  - by hsmit

  In the digital world a lot is stored multiple times. As a thought experiment or creative challenge I want you to think about making this more efficient and maybe reuse more. Think of the following cases: an mp3 track is downloaded multiple times, copied over various devices on website a login form is often rebuild many times, why not reuse more code? words themselves are used many times questions and answers are accidentally saved at many places in parallel images or photos often describe the same data (Eiffel tower, Golden gate, Taj Mahal) etc etc Are you aware of solutions? Or are you thinking about similar topics? Ideas? Blueprints? I'd love to hear from you!

• how big should your controllers be in asp.net-mvc

  - by ooo

  i see the new feature of areas in asp.net-mvc 2. it got me thinking. why would i need this? i did some reading on the use cases and it came down to a specific point to me around how big and how broad scope should my controllers should be? should i try to have many little controllers? one big controller? how do people determine the sweet spot for number of controllers? i think mine are maybe too large (which had me questioning areas in the first place as maybe my controller name should really be an area and have a number of smaller controllers)

• .NET SortedDictionary But Sorted By Values

  - by Michael Covelli

  I need a data structure that acts like a SortedDictionary<int, double> but is sorted based on the values rather than the keys. I need it to take about 1-2 microseconds to add and remove items when we have about 3000 items in the dictionary. My first thought was simply to switch the keys and values in my code. This very nearly works. I can add and remove elements in about 1.2 microseconds in my testing by doing this. But the keys have to be unique in a SortedDictionary so that means that values in my inverse dictionary would have to be unique. And there are some cases where they may not be. Any ideas of something in the .NET libraries already that would work for me?

• Visual Studio - "attach to particular instance of the process" macro

  - by Steve

  I guess prety much everyone who does a lot of debugging have a handy macro in Visual Studio (with shortcut to it on a toolbar) which when called automatically attaches to a particular process (identified by name). it saves a lot of time rather than clicking "Debug" - "Attach to the process ...", but it only works if one is running a single instance of the process one wants to attach to. If theres is more than one instance of particular process in memory - the first one (with a smaller PID?) is being choose by debugger. Does anyone have a macro which shows a dialog (if more that 1 process with a specified name running) and lets developer to select to one he/she really wants to attach to. I guess the selection could be made based on a windwow caption text (which would be suffice in most of cases) and when the particular instance is selected macro passes the PID of the process to the Debugger object? If someone has that macro or knows how to write it - please share. Thanks.

• Help needed inorder to avoid recursion

  - by Srivatsa

  Hello All I have a method, which gives me the required number of Boxes based on number of devices it can hold.Currently i have implemented this logic using recursion private uint PerformRecursiveDivision(uint m_oTotalDevices,uint m_oDevicesPerBox, ref uint BoxesRequired) { if (m_oTotalDevices< m_oDevicesPerBox) { BoxesRequired = 1; } else if ((m_oTotalDevices- m_oDevicesPerBox>= 0) && (m_oTotalDevices- m_oDevicesPerBox) < m_oDevicesPerBox) { //Terminating condition BoxesRequired++; return BoxesRequired; } else { //Call recursive function BoxesRequired++; return PerformRecursiveDivision((m_oTotalDevices- m_oDevicesPerBox), m_oDevicesPerBox, ref BoxesRequired); } return BoxesRequired; } Is there any better method to implement the same logic without using recursion. Cos this method is making my application very slow for cases when number of devices exceeds 50000. Thanks in advance for your support Constant learner

• Checking if date parsing is correct

  - by Javi

  Hello, I have this code for checking whether the Date is OK or not, but it's not ckecking all the cases. For example when text="03/13/2009" as this date doesn't exist in the format "dd/MM/yyyy" it parses the date as 03/01/2010. Is there any way to change this behaviour and getting an exception when I try to parse a Date which is not correct? What's the best way to do this validation? public static final String DATE_PATTERN = "dd/MM/yyyy"; public static boolean isDate(String text){ SimpleDateFormat formatter = new SimpleDateFormat(DATE_PATTERN); ParsePosition position = new ParsePosition(0); formatter.parse(text, position); if(position.getIndex() != text.length()){ return false; }else{ return true; } } Thanks.

• Antlr Lexer Quoted String Predicate

  - by Loki

  I'm trying to build a lexer to tokenize lone words and quoted strings. I got the following: STRING: QUOTE (options {greedy=false;} : . )* QUOTE ; WS : SPACE+ { $channel = HIDDEN; } ; WORD : ~(QUOTE|SPACE)+ ; For the corner cases, it needs to parse: "string" word1" word2 As three tokens: "string" as STRING and word1" and word2 as WORD. Basically, if there is a last quote, it needs to be part of the WORD were it is. If the quote is surrounded by white spaces, it should be a WORD. I tried this rule for WORD, without success: WORD: ~(QUOTE|SPACE)+ | (~(QUOTE|SPACE)* QUOTE ~QUOTE*)=> ~(QUOTE|SPACE)* QUOTE ~(QUOTE|SPACE)* ;

• FileWatcher fires change event after file deletion

  - by florin

  Hi all, I'm using a FileWatcher to trigger processing of files as soon as they are added to a folder. After the file it is processed it is deleted. My problem is that after the file is deleted I get another file change event which is so close to the deletion than in some cases checking for File.Exists it tells that the file still exists. But of course some milliseconds later when looking to process the file it does not really exists. The FileWatcher is set to notify on NotifyFilters.FileName | NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.Size | NotifyFilters.Attributes Thanks, florin

• Limitations in running Ruby/Rails on windows

  - by johnc

  In the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself? EDIT Thanks for the answer around installation and running on Linux, but I am really trying to understand the limitations in functionality as referenced in the installation documentation, and non-working libraries - I am trying to find a link to the comment, but it was referenced in an installation read me when I installed the msi package I think

• Python lazy property decorator

  - by detly

  Recently I've gone through an existing code base and refactored a lot of instance attributes to be lazy, ie. not be initialised in the constructor but only upon first read. These attributes do not change over the lifetime of the instance, but they're a real bottleneck to calculate that first time and only really accessed for special cases. I find myself typing the following snippet of code over and over again for various attributes across various classes: class testA(object): def __init__(self): self._a = None self._b = None @property def a(self): if self._a is None: # Calculate the attribute now self._a = 7 return self._a @property def b(self): #etc Is there an existing decorator to do this already in Python that I'm simply unaware of? Or, is there a reasonably simple way to define a decorator that does this? I'm working under Python 2.5, but 2.6 answers might still be interesting if they are significantly different.

• Avoiding accidentally catching KeyboardInterrupt and SystemExit in Python 2.4

  - by jrdioko

  In Python scripts, there are many cases where a keyboard interrupt (Ctrl-C) fails to kill the process because of a bare except clause somewhere in the code: try: foo() except: bar() The standard solution in Python 2.5 or higher is to catch Exception rather than using bare except clauses: try: foo() except Exception: bar() This works because, as of Python 2.5, KeyboardInterrupt and SystemExit inherit from BaseException, not Exception. However, some installations are still running Python 2.4. How can this problem be handled in versions prior to Python 2.5? (I'm going to answer this question myself, but putting it here so people searching for it can find a solution.)

• Is FastCGI still a right answer?

  - by Ted Henry

  FastCGI is old but it still seems like it must be the right answer in some cases. It seems like the preferred deployment of Perl/Catalyst web applications is with FastCGI. FastCGI was popular with Rails but seems to no longer be. (Why?) The Java world doesn't seem to have anything to do with FastCGI. Is something like Tomcat way better than Apache+FastCGI? Is choosing FastCGI still a good idea or just a lingering technology? Ted

• PDO and SQL IN statements

  Im using a sequel for search like this using PDOs $states = "'SC','SD'"; $sql = "select * from mytable where states in (:states)"; $params = array(':states'=>$states); and I use my function $result = $this->selectArrayAssoc($sql, $params); where my selectArrayAssoc function as following public function selectArrayAssoc($sql, $params = array()){ try{ $sth = $this->db->prepare($sql); $sth->execute($params); $result = $sth->setFetchMode(PDO::FETCH_ASSOC); return $sth->fetchAll(); }catch(PDOException $e){ print $e->getMessage(); //Log this to a file later when in production exit; } } it does not take the quoted variables, I think it is suppressing, in such cases how to deal with this.

• What some good books on software testing/quality?

  - by mjh2007

  I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

• C++, throw exception from initializer list

  - by aaa

  hello. what is the best way to throw exception from initializer list? for example: class C { T0 t0; // can be either valid or invalid, but does not throw directly T1 t1; // heavy object, do not construct if t0 is invalid, by throwing before C(int n) : t0(n), // throw exception if t0(n) is not valid t1() {} }; I thought maybe making wrapper, e.g. t0(throw_if_invalid(n)). What is the practice to handle such cases? Thanks
