It generates some data, based on a parameter. I want the compiler to optimize the data generation for all invocations, where the parameter is known at compile-time. The problem is that I can't force the compiler to put the optimized data out of the stack to a static constant, since marking the data <code>static</code> would break the case when parameter is not a compile-time constant.

Unfortunately, they aren't working. I'm trying to make a simple Java program that can run a compiled Objective-C program (Unix Executable file) with an input parameter. Below are the attempts at Java I have tried that don't seem to be working:</p><br /><br /><pre><code>String[] cmd = {"/bin/bash", fullFilePath, Param};<br />Runtime.getRuntime().exec(cmd);<br /></code></pre><br /><br /><p>This is generating a Processor error of 126 for "Command invoked cannot execute". I've tried other variations that don't work as well such as:</p><br /><br /><pre><code>String[] cmd = {"/bin/bash fullFilePath \"Param\""};<br />String[] cmd = {"/usr/bin/open fullFilePath \"Param\""};<br /></code></pre><br /><br /><p>Any suggestions or ideas on how I can get this to work? I just need to run the compiled Objective-C program in Java with the parameter. I figured it wouldn't be this hard. Thanks in advance, and if you need more information just ask.</p><br/><br/><a rel='nofollow' href='http://stackoverflow.com/questions/4997096/running-a-unix-executable-objective-c-file-in-java-os-x'>Find the answer here</a></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/9204548932714363053-5288796086437753729?l=need-programmer.blogspot.com' alt='' /></div> <p><a href="http://feedads.g.doubleclick.net/~a/cvc5vit8-LWUtJzBe30Gf4_2a6Y/0/da"><img src="http://feedads.g.doubleclick.net/~a/cvc5vit8-LWUtJzBe30Gf4_2a6Y/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/cvc5vit8-LWUtJzBe30Gf4_2a6Y/1/da"><img src="http://feedads.g.doubleclick.net/~a/cvc5vit8-LWUtJzBe30Gf4_2a6Y/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/NeedAProgrammer/~4/A0FKnii8bPM" height="1" width="1"/>The Onehttp://www.blogger.com/profile/15913951498183670546noreply@blogger.com0http://need-programmer.blogspot.com/2011/02/running-unix-executable-objective-c.htmltag:blogger.com,1999:blog-9204548932714363053.post-3610524692414133102011-02-14T12:52:00.003-08:002011-02-14T12:52:31.916-08:002011-02-14T12:52:31.916-08:00<div><h3>Programmer Question</h3> <p>I've done a couple of years of large-scale game server development in PHP. A load balancer delegates incoming requests to one server in a cluster. In the name of better performance, we began caching all static data (essentially the game world's model objects) on each of the instances in that cluster, directly in Apache shared memory, using <code>apc_store</code> and <code>apc_fetch</code>.</p><br /><br /><p>For a number of reasons, we're now beginning to develop a similar game framework in Python, using the Flask microframework. At first glance, this instance's memory store is the one piece that doesn't appear to translate directly to Python/Flask. We're presently considering running Memcached locally on each instance (to avoid streaming fairly large model objects over-the-wire from our main Memcached cluster.)</p><br /><br /><p>What can we use instead?</p><br/><br/><a rel='nofollow' href='http://stackoverflow.com/questions/4964944/whats-a-good-flask-python-wsgi-analog-to-the-php-apache-shared-memory-stores-lik'>Find the answer here</a></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/9204548932714363053-361052469241413310?l=need-programmer.blogspot.com' alt='' /></div> <p><a href="http://feedads.g.doubleclick.net/~a/uE9muZhCDhcIvHkQtavCy21G3Nc/0/da"><img src="http://feedads.g.doubleclick.net/~a/uE9muZhCDhcIvHkQtavCy21G3Nc/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/uE9muZhCDhcIvHkQtavCy21G3Nc/1/da"><img src="http://feedads.g.doubleclick.net/~a/uE9muZhCDhcIvHkQtavCy21G3Nc/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/NeedAProgrammer/~4/3HqpBP1YRkY" height="1" width="1"/>The Onehttp://www.blogger.com/profile/15913951498183670546noreply@blogger.com0http://need-programmer.blogspot.com/2011/02/what-good-flaskpythonwsgi-analog-to-php.htmltag:blogger.com,1999:blog-9204548932714363053.post-87460000911527494952011-02-14T12:52:00.001-08:002011-02-14T12:52:29.731-08:002011-02-14T12:52:29.731-08:00<div><h3>Programmer Question</h3> <p>Trying to match a strings in notepad++ with a regular expression.</p><br /><br /><p>The string I'm trying to match is formatted like this:</p><br /><br /><pre><code>^*^1st Choice Housing.

I will try my best to provide as much information as I can regarding what I am trying to do. </p><br /><br /><p>The simplest thougt is that there are some specified patterns and we want to know whic of these patterns match completely or partially to a given request. The specified patterns hardly change. The amount of requests are about 10K per day but the results have to pe provided ASAP and thus runtime performance is the highest priority.</p><br /><br /><p>I have been thinking of using Assembly Compiled Regular Expression in C# for this, but I am not sure if I am headed in the right direction. </p><br /><br /><p>Scenario:<br/><br />Data File:<br/><br /> Let's assume that data is provided as an XML request in a known schema format. It has anywehere between 5-20 rows of data. Each row has 10-30 columns. Each of the columns also can only have data in a pre-defined pattern. For example: </p><br /><br /><ol><br /><li>A1- Will be "3 digits" followed by a<br />"." follwed by "2 digits" -<br />[0-9]{3}.[0-9]{2} </li><br /><li><p>A2- Will be "1<br />character" follwoed by "digits" -<br />[A-Z][0-9]{4}</p><br /><br /><p>The sample would be something like:</p></li><br /></ol><br /><br /><blockquote><br /><pre><code><Data> <br /> <R1> <br /> <A1>123.45</A1> <br /> <A2>A5567</A2> <br /> <A4>456EV</A4> <br /> <An>xxx</An> <br /> </R1><br /></Data><br /></code></pre><br /></blockquote><br /><br /><p>Rule File: </p><br /><br /><pre><code>Rule ID A1 A2 <br />1001 [0-9]{3}.45 A55[0-8]{2} <br />2002 12[0-9].55 [X-Z][0-9]{4} <br />3055 [0-9]{3}.45 [X-Z][0-9]{4}<br /></code></pre><br /><br /><p>Rule Location - I am planning to store the Rule IDs in some sort of bit mask.<br/><br />So the rule IDs are then listed as location on a string </p><br /><br /><pre><code>Rule ID Location (from left to right) <br />1001 1 <br />2002 2 <br />3055 3<br /></code></pre><br /><br /><p>Pattern file: (This is not the final structure, but just a thought) </p><br /><br /><pre><code>Column Pattern Rule Location<br />A1 [0-9]{3}.45 101<br />A1 12[0-9].55 010 <br />A2 A55[0-8]{2} 100<br />A2 [X-Z][0-9]{4} 011<br /></code></pre><br /><br /><p>Now let's assume that I run the <strong>SOMEHOW</strong> (not sure how I am going to limit the search to save time) I run the regex and make sure that A1 column is only matched aginst A1 patterns and A2 column against A2 patterns. I would end up with the follwoing reults for "Rule Location" </p><br /><br /><pre><code>Column Pattern Rule Location<br />A1 [0-9]{3}.45 101<br />A2 A55[0-8]{2} 100<br /></code></pre><br /><br /><ul><br /><li>Doing AND on each of the loctions<br />gives me the location 1 - 1001 -<br />Complete match.</li><br /><li>Doing XOR on each of the loctions<br />gives me the location 3 - 3055 -<br />Partial match. (I am purposely not<br />doing an OR, because that would have<br />returned 1001 and 3055 as the result<br />which would be wrong for partial<br />match)</li><br /></ul><br /><br /><p>The final reulsts I am looking for are:<br/><br />1001 - Complete Match<br/><br />3055 - Partial Match </p><br /><br /><p>Input:<br/><br />The data will be provided in some sort of XML request. It can be one big request with 100K Data nodes or 100K requests with one data node only.<br/><br />Rules:<br/><br />The matching values have to be intially saved as some sort of pattern to make it easier to write and edit. Let's assume that there are approximately 100K rules. </p><br /><br /><p>Output:<br/><br />Need to know which rules matched completely and partially. </p><br /><br /><p>Preferences:<br/><br />I would prefer doing as much of the coding as I can in C#. However if there is a major performnace boost, I can use a different language. </p><br /><br /><p>The "Input" and "Output" are my requirements, how I manage to get the "Output" does not matter. It has to be fast, lets say each Data node has to be processed in approximately 1 second. </p><br /><br /><p>Questions: </p><br /><br /><ol><br /><li>Are there any existing pattern or<br />framewroks to do this?</li><br /><li>Is using Regex the right path<br />specifically Assembly Compiled<br />Regex?</li><br /><li>If I end up using Regex how can I<br />specify for A1 patterns to only<br />match against A1 column?</li><br /><li>If I do specify rule locations in a<br />bit type pattern. How do I process<br />ANDs and XORs when it grows to be<br />100K charcter long?</li><br /></ol><br /><br /><p>I am looking for any suggestions or options that I should consider. </p><br /><br /><p>Thanks..</p><br/><br/><a rel='nofollow' href='http://stackoverflow.com/questions/4950310/what-would-be-the-best-runtime-performance-application-or-pattern-or-code-or-li'>Find the answer here</a></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/9204548932714363053-1238339106618854750?l=need-programmer.blogspot.com' alt='' /></div> <p><a href="http://feedads.g.doubleclick.net/~a/e8nfoPaWK9wc5RDj04wvCpCNao4/0/da"><img src="http://feedads.g.doubleclick.net/~a/e8nfoPaWK9wc5RDj04wvCpCNao4/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/e8nfoPaWK9wc5RDj04wvCpCNao4/1/da"><img src="http://feedads.g.doubleclick.net/~a/e8nfoPaWK9wc5RDj04wvCpCNao4/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/NeedAProgrammer/~4/8DqQRRcwyng" height="1" width="1"/>The Onehttp://www.blogger.com/profile/15913951498183670546noreply@blogger.com0http://need-programmer.blogspot.com/2011/02/what-would-be-best-runtime-performance.html
