• Regarding BMA-150 Acceleration sensor

  - by vinaykumar

  Hi all, At present i am working on hal part of sensors in android sdk, we are using 3- Axis BMA-150 Accelerometer sensor to get acceleration values with respect to X,y,Z Axis, I want to know whether this sensor will give o/p directly in SI units by using some calibration techniques or what ? , and i noticed that in sensor.c file they mentioned 720.0 LSG = 1G(9.8 m/s2), what is the relation between LSG and acceleration due to gravity? what is meant by LSG why they are multiplying the o/p of accelerometer x,y,z valuse with 9.8/720.0f . please help on this part . Thanks Vinay

• Using Silverlight 4 with ODBC

  - by user1384831

  I'm completely new to Silverlight and I want to connect to a Netezza database with an ODBC connection and pull records to display nicely in Silverlight. What's the easiest way to do this? From some research, it seems creating a WCF RIA service is what most people do ( http://www.codeproject.com/Articles/354715/Creating-a-WCF-RIA-Services-Class-Library-for-a-Si ) but the process seems a bit convoluted. Coming from an ASP.net background, could I do something simpler like creating an ODBC connection in the code-behind (using System.Data.ODBC functionality), executing a query, storing the returned records in a Datatable and then binding that to some Silverlight control?

• Ideas for web development practical jokes?

  - by Ellie P.

  I am a web developer for a Django-based site for a student organization, and I have the opportunity to make the website temporarily absurd for a day of general campus-wide debauchery and chaos (long story, doesn't matter.) What are your best ideas for web development practical jokes (that you could never use in the real world)? For example, one idea we had was to use a client-side script to convert each character to its upside down equivalent in Unicode, si?? ??i? ?ui????os. I'm not necessarily looking for Django-specific solutions. I imagine most of these things would happen on the front-end. I am also quite aware that usability will suffer considerably--the point is to be fun for a day, and there will always be a link to the normal version of the site. Also, everything must be relatively cosmetic and easily reversible--I'm happy to swap out static CSS/JS/HTML/templates/images, and even temporarily add a django view, but no messing with the data level!

• Problem with HTML Parser in IE

  - by Luis Armando

  I am trying to create a dialog box that will appear only if the browser selected is IE (any version) however I get this error: Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) That's all in "Line/Char/Code" 0 so I do not know where is the error. The code I'm using is this: <script type="text/javascript"> <!-- if(BrowserDetect.browser.contains("Explorer")) { var Nachricht = 'Hemos detectado que está utilizando ' + BrowserDetect.browser + ' ' + BrowserDetect.version + '. Puede que algunas funciones no estén habilitadas. <p></p> Si desea experimentar todo el potencial del portal, por favor intente desde otro navegador (browser). <p></p>Gracias showDialog('¡Aviso Importante!',Nachricht,'warning',10); } </script> I've noticed if I remove the "BrowserDetect.browser" and .version it removes the error, but I need those to check =/...any ideas will be appreciated =).

I get mission of to try to recover the database, migrating to another database, and create a cool program to my friend. Now I need to discover wich database was used by the developers.

• How can I set a field to null in a Pre-Update Plugin

  - by Juergen

  I developed a Pre-Update Plugin for the Case entity. In this plugin I want to set a string field to a new value. It works smoothly if the new value is not null. But if the new value si null, it is just ignored. This works: Incident caseTarget = ((Entity) localContext.PluginExecutionContext.InputParameters["Target"]).ToEntity<Incident>(); caseTarget.ProductSerialNumber = "new value"; After the execution of the plugin, the ProductSerialNumber field has value "new value". This doesn't work: Incident caseTarget = ((Entity) localContext.PluginExecutionContext.InputParameters["Target"]).ToEntity<Incident>(); caseTarget.ProductSerialNumber = null; After the execution of the plugin, the ProductSerialNumber field has still its old value. How can I set the target's field to null?

• Read tab delimited text file into MySQL table with PHP

  - by Simon S

  I am trying to read in a series of tab delimited text files into existing MySQL tables. The code I have is quite simple: $lines = file("import/file_to_import.txt"); foreach ($lines as $line_num => $line) { if($line_num > 1) { $arr = explode("\t", $line); $sql = sprintf("INSERT INTO my_table VALUES('%s', '%s', '%s', %s, %s);", trim((string)$arr[0]), trim((string)$arr[1]), trim((string)$arr[2]), trim((string)$arr[3]), trim((string)$arr[4])); mysql_query($sql, $database) or die(mysql_error()); } } But no matter what I do (hence the casting before each variable in the sprintf statement) I get the "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1" error. I echo out the code, paste it into a MySQL editor and it runs fine, it just won't execute from the PHP script. What am I doing wrong?? Si

• Regex for recursive "wiki-style" lists

  - by Syd Miller

  I'm trying to create a Regular Expression to match "wiki style" lists as in (using preg_replace_callback() ): * List Item 1 * List Item 2 *# List Item 2.1 *# List Item 2.2 * List Item 3 Asterisks denote Unordered Lists while Number-Signs denote Ordered Lists. I'm trying to get this so it can match infinite depth and so that * and # can be mixed. I tried the following expression (and variations of it): /\s([*#]{1,}) ([\S ]+)\s/si But it doesn't seem to want to work. What am I doing wrong? Or is there a better way of accomplishing this?

• Visual Studio Symbols stored/loaded from wrong place

  - by werty0u

  Hello, I'm rather new to symbol servers and I've been experimenting with them and Visual Studio 2008 running Windows XP(SP3). I've encountered a wierd problem as my symbols are not being cached locally in the directory I've specified all the time. The possible reasons I have found for this si that the symbols(.pdb's) are being written to VS's IDE directory and/or the symbols are somehow being written in with the .exe, which I find odd since it should be read only. The symbols are being sent to the "server" I've specified so that part of the system shouldn't be the problem. Has anyone else had this type of issue before and/or maybe a solution to this problem? Thanks :)

• JSR 275 - Units, Percent per second

  - by I82Much

  Hi all, I need to represent the unit of Percent per second using the JScience.org's JSR 275 units and measures implementation. I am trying to do to the following: Unit<Dimensionless> PERCENT_PER_SECOND = NonSI.PERCENT.divide(Si.SECOND).asType(Dimensionless.class) but I am getting a ClassCastException when I try to do that. The following works, but I'm not sure if there's a better way: public interface PercentOverTime extends Quantity {} public static Unit<PercentOverTime> PERCENT_PER_SECOND = new BaseUnit<PercentOverTime>("%/s"); Any thoughts? The closest I could find to this is the question on Cooking Measurements (which is how I saw how to define your own units).

• Add links to specific words within span tag in PHP

  - by dazhall

  I have a list of words that I'd like to add a link to, I can do this fairly easily using preg_match_all and preg_replace: $str = "<span class=\"cz\">Dám si jedno pivo prosím.</span> = I'll have a beer please."; preg_match_all('/[a-ztúuýžácdéeínórš]+/i',$str,$matches); $matches = array_unique($matches[0]); foreach ($matches as $match) { if(!empty($words[$match])) { $str = preg_replace("/(^|[^\w]){1}(".preg_quote($match,"/").")($|[^\w]){1}/i", '\\1<a href="#">\\2</a>\\3', $str); } } echo $str; What I'd like to do is restrict the linking to only within the span tag. My brain is all regex-ed out, so any help would be appreciated! Thanks! Darren.

• Practical Python-based visual programming environment?

  - by Who8MyLunch

  I am looking for a practical visual programming environment based on Python. My primary application is algorithm development for processing remote-sensing imagery. I was initially inspired by LabVIEW from National Instruments, but that is more geared towards laboratory measurements and simulations. I write a lot of prototype code in Python and do a lot of interactive analysis with IPython. Does there exist a visual framework where a "program" is represented by connected nodes which each read data, do some work, and output data to the next node? I would like to use Python to write the code residing in each node. So far the best I've seen is Orange http://www.ailab.si/orange/, but it does not have the ability to start/stop individual nodes.

• How to enable/create elements on the fly

  - by Simon S

  Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

• Wordpress database query running slow - one of the columns doesn't exist!

  - by Pavel

  Hi there. I'm having some problems with the query that wordpress runs. That's the one: SELECT DISTINCT ID,post_title,post_date,post_content,MATCH(post_title,post_content) AGAINST ('S') AS score FROM wp_posts WHERE MATCH (post_title,post_content) AGAINST ('S') AND post_date <= 'S' AND post_status = 'S' AND id != N AND post_type = 'S' ORDER BY score DESC When I'm running this query in phpmyadmin it says that N column doesn't exist so clause "AND id != N" si not making any sense. I ran the query again without this clause and db behaved like fully optimized one. Please can someone give me a hint on that? My questions are: What this clause is used for? What wordpress is trying to find by running this and Can I modify core wordpress files to get rid of this clause? Any response or help greatly appreciated!!
