• controlling bluetooth connection in matlab

  - by Mehreen Shahid

  we have a project in which we have to pick randomly generated numbers from a remote device, say mobile. there is a simple java application to generate numbers. next, we have to recieve those numbers in our matlab program via bluetooth connection with the device. assuming those numbers are temperature readings, we want to recieve a new number after every 10 sec and display the number on our matlab GUI program. the problem is do we implement bluetooth protocol through our programming? or use the matlab templates? because otherwise whenever we want to transfer file from a mobile to computer, we have to manually click "recieve a file" in blutooth wizard , just like we normally do to transfer a file. we want to enable the connection once, and then recieve text files after every 10 seconds to be read in our matlab program. can anyone please tell is it even possible in matlab? if yes, how do we establish such an automatic real time connection?

• Caching the repository index in m2eclipse

  - by Titi Wangsa bin Damhore

  everytime i start with a fresh new workspace, m2eclipse downloads nexus-maven-repository-index.gz from the maven central repository. this is good. but, some times, i just want to start a new workspace, and not wait for it to download, it tried copying the whole .metadata directory from an old workspace to the new one, but the list of maven artifacts are still empty. is there a way i can cache it? or at least download the file once, and the copy/extract/repackage it so that m2eclipse thinks it has already downloaded it and allows me to search for maven artifacts. or a short version of the question where and in what format is the "nexus-maven-repository-index.gz" file stored in the workspace?

• Move websites from IIS7 to IIS 7.5

  - by Adam Winter

  Can anyone suggest the best way of moving websites on server1 with IIS7 to server2 with IIS 7.5 on it? I've read some articles which suggest copying the applicationHost.config file while preserving the configProtectedData node, but I'm concerned there may be settings in the IIS 7.5 config that don't exist in the current IIS7 config which would be lost. I've also seen suggestions of moving each site individually by using a command like this: AppCmd.exe LIST SITE "My Site" /config /XML mysite.xml This method just takes too long to do this for dozens of sites. There must be a better way of moving all the sites at once to the new platform.

• MasterPage Page_Load hits before Grid_ItemCommand

  - by Raheel Khan

  I am using the session object to store success/error messages based on user actions. On each postback, the message is set on ItemCommend and retrieved on the Page_Load of the master page. Once retrieved, the message is deleted from the session. The problem is that the master page's Page_Load gets called before the ItemCommand gets called so the message does not show up until the next refresh or postback. How is this situation normally handled? Is there some other event we can code against?

• Analyzing Python Code: Modulus Operator

  - by Bhubhu Hbuhdbus

  I was looking at some code in Python (I know nothing about Python) and I came across this portion: def do_req(body): global host, req data = "" s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, 80)) s.sendall(req % (len(body), body)) tmpdata = s.recv(8192) while len(tmpdata) > 0: data += tmpdata tmpdata = s.recv(8192) s.close() return data This is then called later on with body of huge size, as in over 500,000 bytes. This is sent to an Apache server that has the max request size on the default 8190 bytes. My question is what is happening at the "s.sendall()" part? Obviously the entire body cannot be sent at once and I'm guessing it is reduced by way of the modulus operator. I don't know how it works in Python, though. Can anyone explain? Thanks.

• How Flask loads blueprint internaly?

  - by Ignas B.

  I'm just interested how Flask's blueprints gets imported. It still imports the python module at the end of all the stuff done by Flask and if I'm right python does two things when importing: registers the module name in the namespace and then initialize it if needed. So if Flask blueprint is initialized when it gets registered, so all the module then is in memory and if there are lots of blueprints to register, the memory just gets wasted, because in one request basically you use one blueprint. Not a big loss but still... But if it is only registered in the namespace and initialized only when needed (when the real request reaches it), then it make sense to register them all at once (as is the recommended way I understood). This is I guess the case here :) But just wanted to ask and understand a bit deeper.

• PostgreSQL - select only when specific multiple apperance in column

  - by Horse SMith

  I'm using PostgreSQL. I have a table with 3 fields person, recipe and ingredient person = creator of the recipe recipe = the recipe ingredient = one of the ingredients in the recipe I want to create a query which results in every person who whenever has added carrot to a recipe, the person must also have added salt to the same recipe. More than one person can have created the recipe, in which case the person who added the ingredient will be credited for adding the ingredient. Sometimes the ingredient is used more than once, even by the same person. If this the table: person1, rec1, carrot person1, rec1, salt person1, rec1, salt person1, rec2, salt person1, rec2, pepper person2, rec1, carrot person2, rec1, salt person2, rec2, carrot person2, rec2, pepper person3, rec1, sugar person3, rec1, carrot Then I want this result: person1 Because this person is the only one who whenever has added carrot also have added salt.

• Database Partitioning and Multiple Data Source Considerations

  - by Jeffrey McDaniel

  With the release of P6 Reporting Database 3.0 partitioning was added as a feature to help with performance and data management.  Careful investigation of requirements should be conducting prior to installation to help improve overall performance throughout the lifecycle of the data warehouse, preventing future maintenance that would result in data loss. Before installation try to determine how many data sources and partitions will be required along with the ranges.  In P6 Reporting Database 3.0 any adjustments outside of defaults must be made in the scripts and changes will require new ETL runs for each data source.  Considerations: 1. Standard Edition or Enterprise Edition of Oracle Database.   If you aren't using Oracle Enterprise Edition Database; the partitioning feature is not available. Multiple Data sources are only supported on Enterprise Edition of Oracle   Database. 2. Number of Data source Ids for partitioning during configuration.   This setting will specify how many partitions will be allocated for tables containing data source information.  This setting requires some evaluation prior to installation as       there are repercussions if you don't estimate correctly.   For example, if you configured the software for only 2 data sources and the partition setting was set to 2, however along came a 3rd data source.  The necessary steps to  accommodate this change are as follows: a) By default, 3 partitions are configured in the Reporting Database scripts. Edit the create_star_tables_part.sql script located in <installation directory>\star\scripts   and search for partition.  You’ll see P1, P2, P3.  Add additional partitions and sub-partitions for P4 and so on. These will appear in several areas.  (See P6 Reporting Database 3.0 Installation and Configuration guide for more information on this and how to adjust partition ranges). b) Run starETL -r.  This will recreate each table with the new partition key.  The effect of this step is that all tables data will be lost except for history related tables.   c) Run starETL for each of the 3 data sources (with the data source # (starETL.bat "-s2" -as defined in P6 Reporting Database 3.0 Installation and Configuration guide) The best strategy for this setting is to overestimate based on possible growth.  If during implementation it is deemed that there are atleast 2 data sources with possibility for growth, it is a better idea to set this setting to 4 or 5, allowing room for the future and preventing a ‘start over’ scenario. 3. The Number of Partitions and the Number of Months per Partitions are not specific to multi-data source.  These settings work in accordance to a sub partition of larger tables with regard to time related data.  These settings are dataset specific for optimization.  The number of months per partition is self explanatory, optimally the smaller the partition, the better query performance so if the dataset has an extremely large number of spread/history records, a lower number of months is optimal.  Working in accordance with this setting is the number of partitions, this will determine how many "buckets" will be created per the number of months setting.  For example, if you kept the default for # of partitions of 3, and select 2 months for each partitions you would end up with: -1st partition, 2 months -2nd partition, 2 months -3rd partition, all the remaining records Therefore with records to this setting, it is important to analyze your source db spread ranges and history settings when determining the proper number of months per partition and number of partitions to optimize performance.  Also be aware the DBA will need to monitor when these partition ranges will fill up and when additional partitions will need to be added.  If you get to the final range partition and there are no additional range partitions all data will be included into the last partition.

• Best practice for using web services (ASP.MVC)

  - by eqiz

  Basically what I have is web services returning data in xml format. Once I do a call to a webservice to retrive data from web service function (GetUserList) i want to take that data and then dymaically display (no postback) the resulting information. I know several ways of doing this: webservice sends data back to javascript, javascript then parses, replaces strings or text inside a div or child, or take the information retrieved and then put it into html table format through javascript. Those are some of the idea's i've came up with, does anyone know the best practice to do this? Using ASP.MVC (.Net)

• PHP getting blank pages after submit a form + signal Segmentation fault (11)

  - by Ole Media

  I few days ago I update my macbook pro to snow leopard, and since then some php files are not showing. This is what happens: I created a php form, when going to 'http://localhost/webform.php' I can see the form just fine. Then, once I submit the form, I just get a blank page. I enable error and warnings reporting under php.ini to make sure I'm not missing something, but still I'm not getting anything, just the blank page. Then I checked under apache log files, and what I notice is that every time I submit the form I see the following line coming up under the apache logs: [Wed Apr 07 21:40:28 2010] [notice] child pid 70223 exit signal Segmentation fault (11) I'm clueless on this one. Any ideas on how to fix it?

• Read binary data from a MDB-file running under LAMP

  - by BusterX

  I need to be able to connect to an MDB-file in a LAMP-environment (running on Linux) and ultimately insert converted data into a Mysql db. The data I need to access is stored as a BLOB (Long Binary Data according to Access) in the MDB file. I have not yet been able to actually have a look at the data but I have been told that the BLOB consists of byte strings. Something along the lines of: 0x1c 0x10 0x27 0x00 0x00 I need to parse the byte strings and convert these to a format that is human readable. I do have access to the documentation that explains the various byte strings. So this is really two questions: How do a get access to the MDB file via PHP* (running under LAMP) and read the BLOB (I do not have access to a Windows-platform)? What would be the best way to parse the binary data (in PHP*) once I am able to connect to the MDB-file? *Or are there other methods/languages that are more appropriate?

• jquery document.ready multiple declaration

  - by Hendry H.

  I realized that I can specify $(document).ready(function(){}); more than once. Suppose like this $(document).ready(function(){ var abc = "1122"; //do something.. }); $(document).ready(function(){ var abc = "def"; //do something.. }); Is this standard ? Those codes work on my FF (16.0.2). I just a little afraid that other browser may not. What actually happen ? How jQuery handle those code ? Thanks.

• Best approch for building link in JQuery with paramaters

  - by MrW

  Hi, Very new to JQuery and MVC and webdevelopment over all. I'm now trying to accomplish this and is asking for a bit of advise: I'm basically trying to build a filter with 4 input elements, and 1 output. I have 4 select (drop down) elements in my page. As soon as one of them is changed, I need to build a href and get the partial view with the return values. My questionis now if I should try to build the href in the select element or if I can do it once in jquery, and don't have to have duplicated code. How would I accomplish this?

• How to call an event when the user "finally" selects an item in a list?

  - by herzmeister der welten

  When a user clicks once on an item in a Grid or a ListBox, that item is usually selected, hence most UI frameworks have a onSelected event or the like for that. However, how can we generally call the next step when a user "finally" selects an item by e.g. double clicking an entry? You know when some popup might appear in the context of the selected item and the user can do further stuff. Strangely enough, I think I have never seen a word for that in any UI framework. onPicked, onAccepted, onChosen, onFinallySelected, onResult? All kinda awkward or too special. Any other ideas?

• Windows Workflows - While Activity for creating multiple tasks not working

  - by Georgil Mathew

  I am using a while activity for creating multiple tasks for a workflow. The code is executed fine and the task is created when the loop runs only once. But when the loop runs twice or more, only one task is getting created. Also the WF status shows as Error Occured. All I want to do here is create multiple tasks (no of tasks depends on an entered column value) for the same user. Is it posible to use 'while' in this scenario? Or is there any other way to go ahead? NB: I am using state machine workflow.

• Launching browser within CherryPy

  - by Alan Harris-Reid

  I have a html page displayed using... cherrypy.quickstart(ShowHTML(htmlfile), config=configfile) Once the page is loaded (eg. initiated via. the command 'python mypage.py'), I would like to automatically launch the browser to display the page (eg. via. http://localhost/8000). Is there any way I can achieve this (eg. via. a hook within CherryPy), or do I have to call-up the browser manually (eg. by double-clicking an icon)? TIA Alan

• Database Abstraction & Factory Methods

  - by pws5068

  I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a common-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? Can PEAR interface with the MySqli prepared statements I currently use? Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) Will it slow down my site once I have a significantly large member base?

• Flex chart ItemRollOver behavior

  - by DannyC

  Hi Guys, I'm trying to prevent a default chart item roll over highlight in a Spark column chart. If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent. So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either. Does anyone have any idea what I am missing here? Thanks for reading guys

• n-grams from text in PostgreSQL

  - by harshsinghal

  I am looking to create n-grams from text column in PostgreSQL. I currently split(on white-space) data(sentences) in a text column to an array. select regexp_split_to_array(sentenceData,E'\s+') from tableName Once I have this array, how do I go about: Creating a loop to find n-grams, and write each to a row in another table Using unnest I can obtain all the elements of all the arrays on separate rows, and maybe I can then think of a way to get n-grams from a single column, but I'd loose the sentence boundaries which I wise to preserve. Sample SQL code for PostgreSQL to emulate the above scenario create table tableName(sentenceData text); INSERT INTO tableName(sentenceData) VALUES('This is a long sentence'); INSERT INTO tableName(sentenceData) VALUES('I am currently doing grammar, hitting this monster book btw!'); INSERT INTO tableName(sentenceData) VALUES('Just tonnes of grammar, problem is I bought it in TAIWAN, and so there aint any englihs, just chinese and japanese'); select regexp_split_to_array(sentenceData,E'\s+') from tableName; select unnest(regexp_split_to_array(sentenceData,E'\s+')) from tableName;

• Ruby on Rails: How do you do HTTP auth over multiple controllers?

  - by DerNalia

  So, Here are the relevant routes map.namespace "admin" do |admin| admin.root :controller => :site_prefs, :action => :index admin.resources :site_prefs admin.resources :link_pages admin.resources :menu_bars admin.resources :services admin.resources :users end And I have this for one controller: before_filter :authenticate protected def authenticate authenticate_or_request_with_http_basic do |username, password| username == "1234" && password == "1234" end end How do I set up my admin controllers to authenticate no matter what page within any of those controllers is navigated to, yet only have it authenticate once among all the admin controllers, and have the code all in one spot. Right now, the only I can think of to authenticate is to copy the auth code into each controller, and I hate having duplicate code... so.... yeah

• HTA value update freezes when file copy starts

  Creating an HTA that will automate the installation of several applications it starts by checking for the existence of certain files then copies a large folder to local from a flash drive if it doesn't exist, I have a textbox I'm using to update the current status of the script, but it just seems to freeze and never updates, I haven't had any luck with any of the artificial sleep functions either. here's the segment If Not objFSO.FileExists(Office10Dir) Then MsgBox("Excel is missing") BasicTextBox.Value = "Office14 Not Detected, Copying Source Files to Local" Dim objFS, objFolder Dim OfficeTemp OfficeTemp = "C:\OfficeTemp" Set objFS = CreateObject("Scripting.FileSystemObject") Set objFolder = objFS.CreateFolder(OfficeTemp) objFS.CopyFolder "OfficeTemp", "C:\OfficeTemp" BasicTextBox.Value = "Local Temp Directory Created" ELSE MsgBox("Excel is Installed") END IF All i see is the "Local Temp Directory Created" message once file copy is complete

• Is there a way to allow a property of a user control to be modified only during design time?

  - by Dan

  I've looked into the DesignOnly attribute, but that doesn't seem to accomplish what I want*. Basically, I'm looking for some way to indicate that some property of a user control (let's say Text) can be modified during design time -- i.e., from the Windows Forms designer in VS (or presumably from any GUI designer that can be used to modify a Windows Forms GUI) -- but not during run time. Once the application is running, the property should effectively be readonly. Is this possible? * When I add the DesignOnly attribute to a property, the value I select for that property from design mode doesn't seem to stick; the property just ends up being whatever I have it set to by default in code.

• Can I create a dataset XSD without using the designer?

  - by Per Åkerberg

  Hi everyone, I want to be able to create the XSD file for my typed dataset without using the visual studio dataset designer. Is there a way to do this using for instance a command-line tool? There is some magic happening when a table is dragged from the server explorer to the design surface, but where does that magic come from? To add some flavour to the mix, I am using DB2 LUW 9.1, but I am guessing that the process is similar using other database vendors. Once I have the XSD I can use XSD.exe to create my .CS class, no problem. Thanks for any help or suggestion! /Per

• Getting Started with Fluent NHibernate

  - by Andy

  I'm trying to get into using Fluent NHibernate, and I have a couple questions. I'm finding the documentation to be lacking. I understand that Fluent NHibernate / NHibernate allows you to auto-generate a database schema. Do people usually only do this for Test/Dev databases? Or is that OK to do for a production database? If it's ok for production, how do you make sure that you're not blowing away production data every time you run your app? Once the database schema is already created, and you have production data, when new tables/columns/etc. need to be added to the Test and/or Production database, do people allow NHibernate to do this, or should this be done manually? Is there any REALLY GOOD documentation on Fluent NHibernate? (Please don't point me to the wiki because in following along with the "Your first project" code building it myself, I was getting run-time errors because they forget to tell you to add a reference. Not cool.) Thanks, Andy
