  • What FPGAs (Field-Programmable Gate Arrays) can one buy to experiment with at home?

    - by Joe Blow
    What the heck is an FPGA -- where can I buy one? What sort of system do you need to experiment with them? How to program them? Can you "load" if that's the right terms an FPGA using an ordinary mac or perhaps other *nix or windoze computer? Where can I buy some FPGAs today to experiment with ??! Are they expensive this only available to industry or can I buy one today? Does anyone know about this? Thanks! I have become interested in FPGAs after reading this question... Holistic Word Recognition algorithm in detail

  • Changing all CSS styles with a property via Jquery

    - by Joe
    On a page I include some css eg: <style type='test/css'> .myBox{ color:#000000; border:#FFFFFF; padding:4px; } .myBox2{ color:#000000; border:#FFFFFF; padding:4px; } </style> I want to then change the "color" property set within both myBox and myBox2 in jquery, without knowing the actual name (myBox, myBox2) of the css style. In otherwords, I want to update ALL css styles on the page where color = certain value, and then also update border where = certain value. An example (not valid code) might be: $("all css [color:#000000]").html("#FF0000"); How could this be possible using jquery?

  • DrawRect on the iPhone vs. the Mac

    - by Joe Cannatti
    I am an experienced iPhone dev beginning to work on my first Mac app. One thing that is really throwing me off is the differences between UIView and NSView. It seems that I cannot set the background color of a NSView via interface builder as I can with a UIView. It also seems that I cannot do it by simply sending a setBackgroundColor: message to it. All the examples I have seen are overriding drawRect: in a subclass of NSView. Is that really the only way to do it? What is the conceptual difference here, and why is it this way? NOTE: I am only trying to set the background color to the default grey.

  • How can I detect endianness on a system where all primitive integer sizes are the same?

    - by Joe Wreschnig
    (This question came out of explaining the details of CHAR_BIT, sizeof, and endianness to someone yesterday. It's entirely hypothetical.) Let's say I'm on a platform where CHAR_BIT is 32, so sizeof(char) == sizeof(short) == sizeof(int) == sizeof(long). I believe this is still a standards-conformant environment. The usual way to detect endianness at runtime (because there is no reliable way to do it at compile time) is to make a union { int i, char c[sizeof(int)] } x; x.i = 1 and see whether x.c[0] or x.c[sizeof(int)-1] got set. But that doesn't work on this platform, as I end up with a char[1]. Is there a way to detect whether such a platform is big-endian or little-endian, at runtime? Obviously it doesn't matter inside this hypothetical system, but one can imagine it is writing to a file, or some kind of memory-mapped area, which another machine reads and reconstructs it according to its (saner) memory model.

  • problem using the xsl method for-each

    - by joe
    Using XSL I am trying to turn this XML: <book><title>This is a <b>great</b> book</title></book> into this XML: <book>This is a <bold>great</bold> book</book> using this xsl: <xsl:for-each select="book/title/*"> <xsl:choose> <xsl:when test="name() = 'b'"> <bold> <xsl:value-of select="text()"/> </bold> </xsl:when> <xsl:otherwise> <xsl:value-of select="text()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each> but my output is looking like this: <book><bold>great</bold></bold> Can anyone explain why the root text of <title> is getting lost? I believe my for-each select statement may need to be modified but I can't figure out what is should be. Keep in mind that I cannot use an <xsl:template match> because of the complexity of my style sheet. Thanks!

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

  • PHP - file uploads and ways to prevent viruses from being uploaded in zip/rar archives

    - by Joe
    I am trying to provide a service on my website to allow users to upload files so others can download them. The issue is, since some of these files I will allow to upload will be .zip/.rar files, I am curious as to what ideas exist to help prevent the uploading of archives with Viruses/trojans etc. included. Some .zip files will include legitimate .exe files,though I am not sure what options I have. I thought about it and I don't have a method for verifying with a virus scanner on the server, since I am on shared hosting w/o the option to run a service like that... nor do I have the knowledge on how to do that. I am also aware there is no php class or database to scan the files for viruses. This means, my only options are to rely on: a). manual approval <-- not an acceptable option for me as it might become a busy site with thousands of uploads b). get the users to somehow point out it if has viruses through voting or "flagging", etc.... anyway, regarding "b" - what ideas would you suggest?

  • Database design efficiency with 1 to many relationships limited 1 to 3

    - by Joe
    This is in mysql, but its a database design issue. If you have a one to many relationship, like a bank customer to bank-accounts, typically you would have the table that records the bank-account information have a foreign key that keeps track of the relationship between account and customer. Now this follows the 3rd normal form thing and is a widely accepted way of doing it. Now lets say that you are going to limit a user to only having 3 accounts. The current database implementation will support this and nothing would need to change. But another way to do this would have 3 coloms in the account table that have the id of the 3 respective accounts in them. By the way this violates 1st normal form of db design. The question is what would be the advantage and disadvantages of having the user account relationship recored in this way over the traditional?

  • PHP - Can you help change this function slightly?

    - by Joe
    I have the following function I modified based off someone elses function: function showCombinations($string, $nameString, $linkParts, $i){ $wordDivider = "/"; //the divider between the words/values if ($i >= count($linkParts)){ echo "<a href='".trim($string)."'>".trim($nameString)."</a>, "; } else { foreach ($linkParts[$i] as $currentTrait){ if ($currentTrait['name']=="urltext"){ $currentNameStringName=""; //ignore } else { $currentNameStringName=$currentTrait['name']; } if ($nameString!=""){ $currentNameString=$nameString." - ".$currentNameStringName; } else { $currentNameString=$nameString.$currentNameStringName; } showCombinations($string.$currentTrait['value'].$wordDivider, $currentNameString, $linkParts, $i + 1); } } } showCombinations('', '', $linkParts, 0); All I need to change this to do is, instead of "ECHO", I want it to build up the combination and so I can do: $result = showCombinations('', '', $linkParts, 0); echo $result; I need it this way because I have to modify that $result, not just echo it.

  • Alter top and bottom borders of Dojo/Dijit Dialog and ContentPane

    - by Joe Zitzelberger
    I have a Dojo/Dijit Dialog that contains a FORM. There is a top border between the title bar and the content, and a bottom border below the content. Both are about 19 or 20 pixels high and colored #eeeeee. I can't find these borders in the CSS anywhere -- actually, neither can the IE Developer Toolbar -- they just don't seem to exist as elements. I suspect that Dijit is adding these programatically. Is there any way to just remove these borders? I just want my content to consume all of the dialog area below the title bar. TIA

  • Move the position in JEditorPane

    - by Joe
    Hi, I've a JEditorPane inside a JDialog. I'm loading a web page when this JDialog is loading. This web page is larger then the JEditorPane size. So I want to display a certain position in the web page by default. For example, I've a 175x200 size jdialog and JEditorPane. I want to display the web page sontent around 150 pixels down. Is there any solutions for this? Or is there any other component which I can used to display web pages and can move to a certain position of the web page at loading time.

  • What's a good FOSS java servlet session replication solution

    - by Bossy Joe
    I work on a very high volume public website running on Tomcat 5.5. Currently we require stickiness to a particular server in order to maintain session. I'd like to start replicating session, but have had trouble finding a good FOSS solution. I've written my own Manager (using memcached as the store) but am having trouble dealing with race conditions if more than one server is handling the requests for the same user. Is there a solution out there I should be looking at? I'm looking for not just something that works as a fallback if stickiness fails, but that would work if user requests are regularly spread to multiple servers.

  • How do I pull `static final` constants from a Java class into a Clojure namespace?

    - by Joe Holloway
    I am trying to wrap a Java library with a Clojure binding. One particular class in the Java library defines a bunch of static final constants, for example: class Foo { public static final int BAR = 0; public static final int SOME_CONSTANT = 1; ... } I had a thought that I might be able to inspect the class and pull these constants into my Clojure namespace without explicitly def-ing each one. For example, instead of explicitly wiring it up like this: (def *foo-bar* Foo/BAR) (def *foo-some-constant* Foo/SOME_CONSTANT) I'd be able to inspect the Foo class and dynamically wire up *foo-bar* and *foo-some-constant* in my Clojure namespace when the module is loaded. I see two reasons for doing this: A) Automatically pull in new constants as they are added to the Foo class. In other words, I wouldn't have to modify my Clojure wrapper in the case that the Java interface added a new constant. B) I can guarantee the constants follow a more Clojure-esque naming convention I'm not really sold on doing this, but it seems like a good question to ask to expand my knowledge of Clojure/Java interop. Thanks

  • Amazon S3 permissions

    - by Joe
    Trying to understand S3...How do you limit access to a file you upload to S3? For example, from a web application, each user has files they can upload, but how do you limit access so only that user has access to that file? It seems like the query string authentication requires an expiration date and that won't work for me, is there another way to do this?

  • Javascript function with PHP throwing a "Illegally Formed XML Syntax" error

    - by Joe
    I'm trying to learn some javascript and i'm having trouble figuring out why my code is incorrect (i'm sure i'm doing something wrong lol), but anyways I am trying to create a login page so that when the form is submitted javascript will call a function that checks if the login is in a mysql database and then checks the validity of the password for the user if they exist. however I am getting an error (Illegally Formed XML Syntax) i cannot resolve. I'm really confused, mostly because netbeans is saying it is a xml syntax error and i'm not using xml. here is the code in question: function validateLogin(login){ login.addEventListener("input", function() { $value = login.value; if (<?php //connect to mysql mysql_connect(host, user, pass) or die(mysql_error()); echo("<script type='text/javascript'>"); echo("alert('MYSQL Connected.');"); echo("</script>"); //select db mysql_select_db() or die(mysql_error()); echo("<script type='text/javascript'>"); echo("alert('MYSQL Database Selected.');"); echo("</script>"); //query $result = mysql_query("SELECT * FROM logins") or die(mysql_error()); //check results against given login while($row = mysql_fetch_array($result)){ if($row[login] == $value){ echo("true"); exit(0); } } echo("false"); exit(0); ?>) { login.setCustomValidity("Invalid Login. Please Click 'Register' Below.") } else { login.setCustomValidity("") } }); } the code is in an external js file and the error throws on the last line. Also from reading i understand best practices is to not mix js and php so how would i got about separating them but maintaining the functionality i need? thanks!

  • Does deleting temporary symlinks interrupt current downloads/access to that symlink?

    - by Joe
    I am using symlinks generated in PHP. They are generated when someone requests a download, and I want them to expire at the end of each day. The problem is, what if someone starts downloading a symlink 1 minute before the end of the day and then I delete the symlink while they are downloading it... My question is, to your knowledge will that individual downloading the symlink, right before I delete it, still be able to "download" the file? I am not worried about "resumable download" capability.. but will it make their download stop or break in some way?

  • Check if a GtkEntryCompletion is currently visible

    - by Joe
    I have a GtkEntry with a GtkEntryCompletion attached to it. The Entry does something fairly expensive if the user hasn't changed the text in it for a second (to preview search results). However it's very common for the user to stop typing in order to select the correct autocompletion. So I'd like to delay the preview until the user has stopped typing and the GtkEntryCompletion is not currently suggesting anything. GtkEntryCompletion is not a real widget however, and doesn't seem to have any way to get to whatever widget does own the CellRenderers it uses. Is there a way I can detect if it's visible or not?
