  • C: Pointers to any type?

    - by dragme
    I hear that C isn't so type-safe and I think that I could use that as an advantage for my current project. I'm designing an interpreter with the goal for the VM to be extremely fast, much faster than Ruby and Python, for example. Now I know that premature optimization "is the root of all evil" but this is rather a conceptual problem. I have to use some sort of struct to represent all values in my language (from number over string to list and map) Would the following be possible? struct Value { ValueType type; void* value; } I would store the actual values elsewhere, e.g: a separate array for strings and integers, value* would then point to some member in this table. I would always know the type of the value via the type variable, so there wouldn't be any problems with type errors. Now: Is this even possible in terms of syntax and typing?

  • Pure functional bottom up tree algorithm

    - by Axel Gneiting
    Say I wanted to write an algorithm working on an immutable tree data structure that has a list of leaves as its input. It needs to return a new tree with changes made to the old tree going upwards from those leaves. My problem is that there seems to be no way to do this purely functional without reconstructing the entire tree checking at leaves if they are in the list, because you always need to return a complete new tree as the result of an operation and you can't mutate the existing tree. Is this a basic problem in functional programming that only can be avoided by using a better suited algorithm or am I missing something?

  • Floating point comparison in STL, BOOST

    - by Paul
    Is there in the STL or in Boost a set of generic simple comparison functions? The one I found are always requiring template parameters, and/or instantiation of a struct template. I'm looking for something with a syntax like : if ( is_greater(x,y) ) { ... } Which could be implemented as : template <typename T> bool is_greater(const T& x, const T& y) { return x > y + Precision<T>::eps; }

  • Hudson jobs won't call javac?

    - by Dissonant
    Hi, I have just set up Hudson on my server. For some reason, my build will not call javac to compile my builds...? I have set the path to the JDK in the Manage Hudson area, and it seems to recognise it (doesn't give me a warning). Is there something else I'm supposed to do? Here's a sample console output of one of my jobs (note how javac isn't called at all): Started by user admin Checking out svn+ssh://myhost.com/Project1 A /src/Program.java A build.xml U At revision 119 no change for svn+ssh://myhost.com/Project1 since the previous build Finished: SUCCESS

  • help, stuck with logic variable comparison loop, javascript

    - by Jamex
    I have an input text box for search of input, the id of the text box is: id="search". if a user enters 'cat' at first and hit search. In the function, I get the value 'cat' by using the syntax: var input = document.getElementById("search").value; After that, the user enter 'dog' in the search box and hit search using the same function. The function would assign 'dog' to the input variable. How would I compare the current value (dog) to the previously entered value (cat)? I have tried to assign the original input with a statement, something like var orig = input; but that would only overwrite the original input with the new input. What is the logical approach to this problem.

  • Can I stop ASP.NET from returning 'The resource cannot be found.'?

    - by mackenir
    I have installed an HttpModule into my web app that will handle all requests with a given file extension. I want ASP.NET to handle all requests with the extension, regardless of whether there is an underlying file on disk. So, when I added the extension to the 'Application Extension Mappings', I unchecked the 'Verify that file exists' checkbox. However, this just transfers the file check to ASP.NET rather IIS, so I just get a different error page when requesting URLs with the file extension. Is there a way to preempt this ASP.NET file checking and intercept the requests?

  • Problem with parsing SQL into table variable

    - by Stanley Ross
    I'm using the following code to read a SQL XML Variable into a table variable. I am getting the following error. " Incorrect syntax near '.'. " Can't quite Figure it out DECLARE @LOBS Table ( LineGUID varchar(40) ) DECLARE @lg xml SET @lg = '<?xml version="1.0" encoding="utf-16" standalone="yes"?> <Table> <LOB> <LineGuid>d6e3adad-8c53-4768-91a3-745c0dae0e08</LineGuid> </LOB> <LOB> <LineGuid>4406db8f-0d19-47da-953b-afc1db38b124</LineGuid> </LOB> </Table>' INSERT INTO @LOBS(LineGUID) SELECT ParamValues.ID.value('.','VARCHAR(40)') FROM @lg.nodes('/Table/LOB/LineGuid') AS ParamValues(ID)

  • Exploring search options for PHP

    - by Joshua
    I have innoDB table using numerous foreign keys, but we just want to look up some basic info out of it. I've done some research but still lost. 1) How can I tell if my host has Sphinx installed already? I don't see it as an option for table storage method (i.e. innodb, myisam). 2) Zend_Search_Lucene, responsive enough for AJAX functionality of millions of records? 3) Mirror my innoDB with a myisam? Make every innodb transaction end with a write to the myisam, then use 1:1 lookups? How would I do this automagically? This should make MyISAM ACID-compliant and free(er) from corruption no? 4) PostgreSQL fulltext queries don't even look like SQL to me wtf, I don't have time to learn a new SQL syntax I need noob options 5) ???????????????????? This is high volume site on a decently-equipped VPS Thanks very much for any ideas.

  • Commit SVN working copy into Git repository

    - by mchr
    I am currently working on a checked out SVN project along with some plugins for that project. I want to keep all of this work - including the current version of my SVN checkout within a single git repository. I thought I had achieved this by checking in the SVN working copy to git. However, when I did a pull on a new computer the SVN working copy had been corrupted. In particular it seemed that git had not checked it any of the .svn/tmp/ and .svn/props/ folders. I have now made a fresh checkout of the SVN project. Is there a way for me to add the ignored folders to my git repo (git status ignores them even though my .gitignore is empty) or force SVN to regenerate them?

  • Is there a function that can read a php function post-parsing?

    - by Rob
    I've got a php file echoing hashes from a MySQL database. This is necessary for a remote program I'm using, but at the same time I need my other php script opening and checking it for specified strings POST parsing. If it checks for the string pre-parsing, it'll just get the MySQL query rather than the strings to look for. I'm not sure if any functions do this. Does fopen() read the file prior to parsing? or file_get_contents()? If so, is there a function that'll read the file after the php and mysql code runs? The file with the hashes query and echo is in the same directory as the php file reading it, if that makes a difference. Perhaps fopen reads it post-parse, and I've done something wrong, but at first I was storing the hashes directly in the file, and it was working fine. After I changed it to echo the contents of the MySQL table, it bugged out.

  • mysql replace matching but not changing

    - by alex
    I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work-it matches the rows, but doesn't replace. Here's what I'm trying to do: mysql> update contained_widgets set preference_values = replace(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

  • Need a good way to share iPhone source code on the Web.

    - by CJCraft.com
    Hi, I'm looking for a way to share some iPhone SDK source code I have with others. Goals: Share iPhone SDK source code, Objective C written in XCode. I have a good bit of source code I want to share. I'd like for it to be easy. I'd like for it to have syntax highlighting, by this I mean coloring and formatting Ideally it would allow me some room to make it "fit" into my site. I want it to look like basically another page on my site where the content is the code. It shouldn't be just a text file in other words. Here's an example where someone was able to do this for C#: http://www.opennetcf.com/library/sdf/ I guess what I want is the ability to create html documentation for all the classes, etc.

  • Is it possible to find out what FlashBuilder is doing during compilation?

    - by justkevin
    I've found that Flash Builder 4 (formerly Flex Builder) has trouble working with large projects. After a certain point, builds seem to take longer and longer. I've tried many different ways of improving build time including: Moving embedded resources into externally linked projects. Using -incremental. Tweaking the .ini jvm settings including memory and -server. Turning off automatic build (I'd prefer not to have to do this, because one of the main reasons for using an IDE is to be told about errors as you make them). Deleting the project and re-checking out from the repository. While some of these may help a bit, the performance is still annoyingly slow. I feel if I knew what was taking so long I could refactor my projects to build faster. Is there some setting that tells FlashBuilder to let me see what parts of the build process take so much time?

  • Extracting property names from a c# source file

    - by Pete
    I want to parse a c# file. The only thing I want is to determine if it contains a property with a specific name; just a simple true/false response. Or rather, since I'd checking for more than one property in each run, extracting a list of property names could be helpful I thought that I could create an elegant solution using the CodeDomProvider functionality (f# example): use reader = new StreamReader(existingFile) let codeProvider = new CSharpCodeProvider() let codeUnit = codeProvider.Parse(reader) Unfortunately, the Parse function is not implemented for the CSharpCodeProvider. Is there a way to get a CodeCompileUnit from a source file? Or is there another elegant way? (I had hoped to avoid regular expressions on this)?

  • NSArray vs. SQLite for Complex Queries on iPhone

    - by GingerBreadMane
    Developing for iPhone, I have a collection of points that I need to make complex queries on. For example: "How many points have a y-coordinate of 10" and "Return all points with an X-coordinate between 3 and 5 and a y-coordinate of 7". Currently, I am just cycling through each element of an NSArray and checking to see if each element matches my query. It's a pain to write the queries though. SQLite would be much nicer. I'm not sure which would be more efficient though since a SQLite database resides on disk and not in memory (to my understanding). Would SQLite be as efficient or more efficient here? Or is there a better way to do it other than these methods that I haven't thought of? I would need to perform the multiple queries with multiple sets of points thousands of times, so the best performance is important.

  • very weird problem concerning date and time in silverlight + ria services

    - by Patrick LHM
    Hello Friends i'm facing a very weird problem in sliverlight 4 + RIA Services, or maybe it's not weird and i'm just a newbie anyway i hope someone here can help, the problem is the following i've created a function on the server side inside the domain service this function is very simple and has a line in it that adds the server current date and time to the database (it's an HR application and employees should sign in and out thrue it each from it's own pc ) Emp.TimeOut = system.DateTime.now (C# syntax) the weird part is that for some users it always adds 3 hours to the current time(exp if he signes out at 5 it shows 8) and for others it works perfectly. the server and all the stations in the company have exactly the same time settings and the same time zone, and anyway my fucntion is on the server side so it should no be realted to the users time. any ideas why this is happening ? i've bin trying to find out why for days now but with no luck

  • script to dynamically fix ophaned users after db restore

    After performing a database restore, I want to run a dynamic script to fix ophaned users. My script below loops through all users that are displayed after executing sp_change_users_login 'report' and apply "alter user [username] with login = [username]" to fix SID conflicts verses static go statements.

  • get entire line with java.util.scanner.hasNext(regex)

    - by Hussain
    I'm doing something in Java that requires input to be matched against the pattern ^[1-5]$. I should have a while loop looping through each line of input, checking it against the pattern, and outputting an error message if it does not. Sudo code: while (regex_match(/^[^1-5]$/,inputLine)) { print ("Please enter a number between 1 and 5! "); getNextInputLine(); } I can use java.util.Scanner.hasMatch("^[^1-5]$"), but that will only match a single token, not the entire line. Any idea on how to make hasMatch match against the entire line? (Setting the delimiter to "\n" or "\0" doesn't work.)

  • Mod_rewrite with multiple variables

    - by Andrei
    Hello, I'm using a PHP script that dynamically generates transparent PNGs for use as CSS backgrounds from a query string that takes RGBa and HSLa values. The original script can be found here, I've only added HSLa support. Because background URLs with PHP query strings aren't very pretty, and because it seems to break the IE 6 transparent PNG hack, I thought of using mod_rewrite to allow the script to be called when a .png with this syntax is called : /assets/colors/h[0-360 value]_s[0-100 value]_l[0-100 value]_a[0-100 value].png which would be rewritten to : /assets/colors.php?h=[0-360 value]&s=[0-100 value]&l=[0-100 value]&a=[0-100 value] Here's the issues I'm encountering : passing multiple variables with mod_rewrite using an underscore as a delimiter I know this could be done by passing a single variable and then exploding it in the PHP script, however I would prefer it to be done by Apache. Thanks in advance and if anyone wants my HSLa enabled version of the script just ask. Anyway I recommend you check it out on it's author's website.

  • Get Average Using LINQ

    - by obautista
    Hoping someone can help me with the LINQ syntax to calculate an average. For example, I have the following LINQ query: var rates = from rating in ctx.Rates where rating.Id == Id select new { UserId = rating.UserId, Rating = rating.Rating }; If 10 records are returned, I need to calculate average on the Rating field. It is defined as as a Double in my DB. I am using LINQ to EF. So I would be assigning the UserId, MiscId, and the Rating would be the average on the records returned. I am passing one object back to the client code.

  • Why are cookies only sent to http://www.example.com and NOT http://example.com?

    - by Axel
    I have a PHP login which sets 2 cookies once someone login. The problem is that if you login from http://www.example.com and you go to http://example.com, you will find yourself not logged in. I think that is because the browser only send the cookies to the first syntax. It is only one domain, the difference is the www. before the domain name, so how to set cookies to the whole domain whatever there is www. or not? <?php setcookie('username',$username,time()+3600); ?>
