  • How to configure LAMP server for iOS social/chat app?

    - by andufo
    I'm on the last developing phase of a social networking app for iOS that has a chat module. Right now I'm trying to figure out the best way to achieve these features: Send message instantly to another user. If other user is online, delivery should be instantly. If user reads the message, the remitent should be notified of that action. If a user visits my profile, I should be notified instantly. What would be, in your opinion, the best approach to achieve that experience? The server is CentOS 5.6. I've previously reviewed XMPP, sockets, but I'm still unsure on what the best approach is. Any opinions and resources will be much appreciated.

  • Using LDAP/Active Directory with PIN based authentication

    - by nishantjr
    We'd like to integrate our service with LDAP, but because of hardware constraints, we're only allow 4 digit user ids and passwords. What would be the best practice for performing such an authetication? We've considered adding User ID and PIN attributes to the LDAP user schema, but we're not sure how happy people would be with modifying their schema to interact with our service. The PIN attribute would have to have the same support that native user passwords have. (hashing and salting etc.) UPDATE Another consideration is how ldap_bind works with this scenario. How do we get it to use an alternate authentication method? Can this even be done without affecting other services that use the same LDAP server?

  • What sysadmin must do to run OS with damaged /lib/libc.so file ? / rsyslogd daemon logrotation / deny checking list of running processes

    - by Virtual_Lotos
    What sysadmin must do to run OS with damaged /lib/libc.so file ? In other words, how command interpreter should be configured to be able to run system with corrupted /lib/libc.so file ? Do I have to move it to /var catalog ? Does the command interpreter must be statically compiled or have setuid attribute or perhaps must be a symbolic link to /bin/sh or must be no larger than 2MB ? How to prevent a user from checking list of processes started by another user ? How do I forbid a user to see which processes are running by another user ? What do I have to keep in mind when I want to make rsyslogd daemon logrotation ?

  • Apache: Use requested directory as a parameter

    - by friendlycello
    Here's what I'd like to do: If a user goes to www.example.com/thislocation, I'd like to redirect to a particular script and give it "thislocation" as a parameter. So if a user navigated to www.example.com/thislocation, I'd like to redirect to www.example.com/cgi-bin/test.pl?parameter=thislocation, and similarily, if the user navigated to www.example.com/thatlocation, I'd like to redirect to www.example.com/cgi-bin/test.pl?parameter=thatlocation. Is this possible with Apache?

  • How to deploy new instances of the same application (on 1 server) automatically?

    - by Intru
    I'm working on a SaaS application where each customer runs its own version of the application. All the application instances currently run on a single server. This works quite well for us (we need less resources in total). The application doesn't use a lot of resources, so even a small VPS would be overkill (and more expensive). Adding a new customer is currently quite a bit of work: Create a user that is allowed to ssh Create a new MySQL database and user Create a virtual host for the application Log in with the new user, do a git checkout of the application (in the right location) Create tables in the new database, and add some init data Add some cron jobs Create a first user that can log in Add this new instance to capistrano What would be the best way to automate these tasks? Are the applications that can (given proper configuration) do this? Ideally this should be usable for a sales-person (so something web-based). I could write a (bash) script that does most of these tasks, and then maybe add a small web-based wrapper where someone could provider the domain/default user information. Of course, this would also require a delete-script, since some customers will eventually leave, which means that you need a list of all existing customers/instances.

  • Winodws server 2003 Setup

    - by Barracksbuilder
    I work at a university maintaining the computer science department server. I am looking for a more economical way to stream line the set up of student accounts. CS students are granted a Username and password an IIS virtual directory, FTP virtual directory, and a mysql database. Server is running windows server 2003R2 (Possibly migrating to 2008R2) The server is running a domain though no students physically log a terminal into it (No computers are part of my domain.) Creating the account is a manual process. I did right a PHP script to query the Universities AD and copy the information and write it to my AD. I then have to create basically the users home directory. I tried having AD do it but since the user never physically logs in it never creates the directory. Permissions on this folder are set to User - full, Instructors (group) - full, Users (group) - read, IUSER - read. Inside of the users folder their is a "Private" folder with permissions User - full, instructors (group) - full. Next step is IIS I create a virtual directory in the default web site pointed to the users home directory so they have a website. Same goes for FTP virtual directory in the default ftp configuration to allow the users to upload files to their website. Mysql I have to create a user and password then create a mysql scheme (database) full access for the user and full access to the instructors account to be able to access the students database. All of this is done manually and takes me a week to do. The closest description is maybe a shared hosting environment. Is there a better way to do this? Scripting wise, or better structure setup?

  • Windows 7 : access denied to ONE server from ONE computer

    - by Gregory MOUSSAT
    We have a domain served by some Windows 2003 servers. We have several Windows 7 Pro clients. ONE client computer can't acces ONE member Windows 2003 server. The other computers can acces every servers. And the same computer can access other servers. With explorer, the message says the account is no activated. With the command line, the message says the account is locked. With commande line : net use X: \\server\share --> several seconds delay, then error (says the account is locked) net use X: \\server\share /USER:current_username --> okay net use X: \\server\share /USER:domain_name\current_username --> okay From the same computer, the user can access other servers. From another computer, the same user can access any server, including the one denied from the original computer. Aleady done : unjoin then join the cilent from the domain. check the logs on the server : nothing about the failed attempts (?!) Is their any user mapping I'm not aware of ?

  • PHP CPU utilization limit

    - by knightrider
    I have done some research on the net regarding the problem. My questions is NOT how to reduce cpu utilization by improving algorithm or improving the performance by using multitasking or limiting CPU per system user. I have a website where user logs in does some processing and logout. The site uses linux server, php and apache. The problem is that I cant control the amount of CPU allocated to each user. ie I want give a guarantee that a user will get say atleast 5% of CPU (assume total number of users is less than 20). How can I do this? Any solution (A php code, apache server settings, or any out of box soln) is welcomed. Thankyou very much for reading this :)

  • Is there any script to do accounting for the proftpd's xferlog?

    - by Aseques
    I would like to convert from the xferlog format that proftpd uses into per user in/out bytes, to have a summary on how much traffic does each user use per month. The exact format is this: Thu Oct 17 12:47:05 2013 1 123.123.123.123 74852 /home/vftp/doc1.txt b _ i r user ftp 0 * c Thu Oct 17 12:47:06 2013 2 123.123.123.123 86321 /home/vftp/doc2.txt b _ i r user ftp 0 * c So far I only found a script that makes a nice report but not exactly what I needed, that one can be found here I might create a fork of this one and place it somewhere but it probably has been done a lot of times already. Just found a well hidden page in proftpd site with some more examples here

  • sticky bit on NFS file system

    - by Kris_R
    I have a system where to the main server (homes, nfs, ntp, queue...) can log-in only root – all the other users use front-end host with NFS-mounted home directories (RW) and all other software directories (read-only). My problem is, that time to time, if root or normal user with sudo makes some administrative works on front-end some homes of normal users getting sticky bits (drwsr-sr-x). If it happens usually the user can't log-in (as long as permission for his home are not changed to drwxr-xr-x). The last time I saw it after compiling some new software (normal user configure;make) and installation from the same directory as root (su and make install or direct as normal user sudo make install). Can somebody explain me why it happens and what should I do to get rid of this problem? p.s. I'm using CentOS 5.7

  • Ubuntu 10.04 Apache Configuration for Websites

    - by completenoob
    Looking at a basic Ubuntu 10.04 server setup, Apache points to /var/www for where to it looks for files to serve up. The default apache user is www. I'm just trying to set up a plain old WordPress blog. Should I just dump the files into /var/www/ as root or www? User www seems inconvenient since I won't log in as the user, but I guess I can chown the files in /var/www to www. Not that I would log in as root either, but what is the recommended user who should own the /var/www files? Thanks for the help.

  • Old network login passed to IIS

    - by 300 baud
    Let me start by saying that I am not a server guy - I am a developer. But I develop and manage an ASP.NET application that uses Windows authentication. I've run into the problem I am about to describe before, and I would just like to understand how to remedy it since I am the one who always gets the original support request. A user, let's call her JaneDoe, has just gotten married and her login has been changed to JaneJones. We have an application that uses Windows authentication to store the user's login name to a table and then redirects the user to another non-Windows authenticated site with a GUID which points to the table entry we just made. When the user reaches the second site, we read in the login name from the database using the GUID that was passed. Then, we look up the login name in another database where we track application permissions. The problem is that the user is logging into her workstation as JaneJones, but the Windows authenticated site is still receiving a login name of JaneDoe. Is this a domain controller issue? Is it a workstation issue? What's the best way to resolve this?

  • How to disable multiple form submit (POST) in IIS

    - by user1209640
    We had a major SharePoint outage a few months back because a user wedged their keyboard in such a way as to cause the Enter button to be pressed indefinitely. The user was on a customized people search page and hundreds of POSTs by the same user were submitted asynchronously, which overloaded the server. Because I work in a large organization, I am looking for a more global way to prevent this from happening. Is there a way to prevent multiple web form submissions by a common user within a short period of time within IIS? I am aware we can write javascript to disable the button after it is clicked, but we are hoping to prevent this issue from occurring on other pages where a similar possibility may exist. Update: It appears looking at the source code, the javascript is performing a document.location = url, whenever keycode 13 (Enter) is pressed. Again, we can write JS to prevent this in this location, but we also want to be able to guard against this kind of issue more generally... preferably at the IIS level.

  • Intermittent 403 errors when using allow to limit access to url with both explicit IP and SetEnvIf

    - by rbieber
    We are running Apache 2.2.22 on a Solaris 10 environment. We have a specific URL that we want to limit access to by IP. We recently implemented a CDN and now have the added complexity that the IP's that a request are shown to be coming from are actually the CDN servers and not the ultimate end user. In the case that we need to back the CDN out, we want to handle the case where either the CDN is forwarding the request, or the ultimate client is sending the request directly. The CDN sends the end user IP address in an HTTP header (for this scenario that header is called "User-IP"). Here is the configuration that we have put in place: SetEnvIf User-IP (\d+\.\d+\.\d+\.\d+) REAL_USER_IP=$1 SetEnvIf REAL_USER_IP "(10\.1\.2\.3|192\.168\..+)" access_allowed=1 <Location /uri/> Order deny,allow Allow from 10.1.2.3 192.168. allow from env=access_allowed Deny from all </Location> This seems to work fine for a time, however at some point the web server starts serving 403 errors to the end user - so for some reason it is restricting access. The odd thing is that a bounce of the web server seems to resolve the issue, but only for a time - then the behavior comes back. It might be worthwhile to note as well that this URL is delegated to a JBoss server via mod_jk. The denial of access is, however; confirmed to be at the Apache layer and the issue only seems to happen after the server has been running for some time.

  • permissions on upload folder not working

    - by Camran
    I have a php script which uploads images to a folder. I have these permissions on the upload folder: drwxrwxr-- 4 user user 4096 2010-06-02 16:20 temp_images Shouldn't these permissions be enough for files to be uploaded to the folder? But this doesn't work. It only works when I set the permissions to 777. "user" is added to the www-data group, still no luck. Any ideas why?

  • Creating a multi-tenant application using PostgreSQL's schemas and Rails

    - by ramon.tayag
    Stuff I've already figured out I'm learning how to create a multi-tenant application in Rails that serves data from different schemas based on what domain or subdomain is used to view the application. I already have a few concerns answered: How can you get subdomain-fu to work with domains as well? Here's someone that asked the same question which leads you to this blog. What database, and how will it be structured? Here's an excellent talk by Guy Naor, and good question about PostgreSQL and schemas. I already know my schemas will all have the same structure. They will differ in the data they hold. So, how can you run migrations for all schemas? Here's an answer. Those three points cover a lot of the general stuff I need to know. However, in the next steps I seem to have many ways of implementing things. I'm hoping that there's a better, easier way. Finally, to my question When a new user signs up, I can easily create the schema. However, what would be the best and easiest way to load the structure that the rest of the schemas already have? Here are some questions/scenarios that might give you a better idea. Should I pass it on to a shell script that dumps the public schema into a temporary one, and imports it back to my main database (pretty much like what Guy Naor says in his video)? Here's a quick summary/script I got from the helpful #postgres on freenode. While this will probably work, I'm gonna have to do a lot of stuff outside of Rails, which makes me a bit uncomfortable.. which also brings me to the next question. Is there a way to do this straight from Ruby on Rails? Like create a PostgreSQL schema, then just load the Rails database schema (schema.rb - I know, it's confusing) into that PostgreSQL schema. Is there a gem/plugin that has these things already? Methods like "create_pg_schema_and_load_rails_schema(the_new_schema_name)". If there's none, I'll probably work at making one, but I'm doubtful about how well tested it'll be with all the moving parts (especially if I end up using a shell script to create and manage new PostgreSQL schemas). Thanks, and I hope that wasn't too long! UPDATE May 11, 2010 11:26 GMT+8 Since last night I've been able to get a method to work that creates a new schema and loads schema.rb into it. Not sure if what I'm doing is correct (seems to work fine, so far) but it's a step closer at least. If there's a better way please let me know. module SchemaUtils def self.add_schema_to_path(schema) conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{schema}, #{conn.schema_search_path}" end def self.reset_search_path conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{conn.schema_search_path}" end def self.create_and_migrate_schema(schema_name) conn = ActiveRecord::Base.connection schemas = conn.select_values("select * from pg_namespace where nspname != 'information_schema' AND nspname NOT LIKE 'pg%'") if schemas.include?(schema_name) tables = conn.tables Rails.logger.info "#{schema_name} exists already with these tables #{tables.inspect}" else Rails.logger.info "About to create #{schema_name}" conn.execute "create schema #{schema_name}" end # Save the old search path so we can set it back at the end of this method old_search_path = conn.schema_search_path # Tried to set the search path like in the methods above (from Guy Naor) # conn.execute "SET search_path TO #{schema_name}" # But the connection itself seems to remember the old search path. # If set this way, it works. conn.schema_search_path = schema_name # Directly from databases.rake. # In Rails 2.3.5 databases.rake can be found in railties/lib/tasks/databases.rake file = "#{Rails.root}/db/schema.rb" if File.exists?(file) Rails.logger.info "About to load the schema #{file}" load(file) else abort %{#{file} doesn't exist yet. It's possible that you just ran a migration!} end Rails.logger.info "About to set search path back to #{old_search_path}." conn.schema_search_path = old_search_path end end

  • Using xsl:variable in a xsl:foreach select statment

    - by Nefariousity
    I'm trying to iterate through an xml document using xsl:foreach but I need the select=" " to be dynamic so I'm using a variable as the source. Here's what I've tried: ... <xsl:template name="SetDataPath"> <xsl:param name="Type" /> <xsl:variable name="Path_1">/Rating/Path1/*</xsl:variable> <xsl:variable name="Path_2">/Rating/Path2/*</xsl:variable> <xsl:if test="$Type='1'"> <xsl:value-of select="$Path_1"/> </xsl:if> <xsl:if test="$Type='2'"> <xsl:value-of select="$Path_2"/> </xsl:if> <xsl:template> ... <!-- Set Data Path according to Type --> <xsl:variable name="DataPath"> <xsl:call-template name="SetDataPath"> <xsl:with-param name="Type" select="/Rating/Type" /> </xsl:call-template> </xsl:variable> ... <xsl:for-each select="$DataPath"> ... The foreach threw an error stating: "XslTransformException - To use a result tree fragment in a path expression, first convert it to a node-set using the msxsl:node-set() function." When I use the msxsl:node-set() function though, my results are blank. I'm aware that I'm setting $DataPath to a string, but shouldn't the node-set() function be creating a node set from it? Am I missing something? When I don't use a variable: <xsl:for-each select="/Rating/Path1/*"> I get the proper results. Here's the XML data file I'm using: <Rating> <Type>1</Type> <Path1> <sarah> <dob>1-3-86</dob> <user>Sarah</user> </sarah> <joe> <dob>11-12-85</dob> <user>Joe</user> </joe> </Path1> <Path2> <jeff> <dob>11-3-84</dob> <user>Jeff</user> </jeff> <shawn> <dob>3-5-81</dob> <user>Shawn</user> </shawn> </Path2> </Rating> My question is simple, how do you run a foreach on 2 different paths?

  • FOSUserBundle override mapping to remove need for username

    - by musoNic80
    I want to remove the need for a username in the FOSUserBundle. My users will login using an email address only and I've added real name fields as part of the user entity. I realised that I needed to redo the entire mapping as described here. I think I've done it correctly but when I try to submit the registration form I get the error: "Only field names mapped by Doctrine can be validated for uniqueness." The strange thing is that I haven't tried to assert a unique constraint to anything in the user entity. Here is my full user entity file: <?php // src/MyApp/UserBundle/Entity/User.php namespace MyApp\UserBundle\Entity; use FOS\UserBundle\Model\User as BaseUser; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; /** * @ORM\Entity * @ORM\Table(name="depbook_user") */ class User extends BaseUser { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; /** * @ORM\Column(type="string", length=255) * * @Assert\NotBlank(message="Please enter your first name.", groups={"Registration", "Profile"}) * @Assert\MaxLength(limit="255", message="The name is too long.", groups={"Registration", "Profile"}) */ protected $firstName; /** * @ORM\Column(type="string", length=255) * * @Assert\NotBlank(message="Please enter your last name.", groups={"Registration", "Profile"}) * @Assert\MaxLength(limit="255", message="The name is too long.", groups={"Registration", "Profile"}) */ protected $lastName; /** * @ORM\Column(type="string", length=255) * * @Assert\NotBlank(message="Please enter your email address.", groups={"Registration", "Profile"}) * @Assert\MaxLength(limit="255", message="The name is too long.", groups={"Registration", "Profile"}) * @Assert\Email(groups={"Registration"}) */ protected $email; /** * @ORM\Column(type="string", length=255, name="email_canonical", unique=true) */ protected $emailCanonical; /** * @ORM\Column(type="boolean") */ protected $enabled; /** * @ORM\Column(type="string") */ protected $salt; /** * @ORM\Column(type="string") */ protected $password; /** * @ORM\Column(type="datetime", nullable=true, name="last_login") */ protected $lastLogin; /** * @ORM\Column(type="boolean") */ protected $locked; /** * @ORM\Column(type="boolean") */ protected $expired; /** * @ORM\Column(type="datetime", nullable=true, name="expires_at") */ protected $expiresAt; /** * @ORM\Column(type="string", nullable=true, name="confirmation_token") */ protected $confirmationToken; /** * @ORM\Column(type="datetime", nullable=true, name="password_requested_at") */ protected $passwordRequestedAt; /** * @ORM\Column(type="array") */ protected $roles; /** * @ORM\Column(type="boolean", name="credentials_expired") */ protected $credentialsExpired; /** * @ORM\Column(type="datetime", nullable=true, name="credentials_expired_at") */ protected $credentialsExpiredAt; public function __construct() { parent::__construct(); // your own logic } /** * @return string */ public function getFirstName() { return $this->firstName; } /** * @return string */ public function getLastName() { return $this->lastName; } /** * Sets the first name. * * @param string $firstname * * @return User */ public function setFirstName($firstname) { $this->firstName = $firstname; return $this; } /** * Sets the last name. * * @param string $lastname * * @return User */ public function setLastName($lastname) { $this->lastName = $lastname; return $this; } } I've seen various suggestions about this but none of the suggestions seem to work for me. The FOSUserBundle docs are very sparse about what must be a very common request.

  • how get validation messages from mangomapper using rails console ?

    - by Alex
    Hi, I am basically teaching myself how to use RoR and MongoDB at the same time. I am following the very good book / tutorial : http://railstutorial.org/ I decided to replace Sqlite3 by MongoDB using the mongomapper gem. Everything works out about alright, but I am having some non-blocking little issues that I truly wish I could get rid of. In chapter 6, when working with validation I got 2 issues: - I don't know how to get the validations messages back like with Sqlite3. The "standard" code is: $ rails console --sandbox >> user = User.new(:name => "", :email => "[email protected]") >> user.save => false >> user.valid? => false >> user.errors.full_messages => ["Name can't be blank"] but if I try to do the same with MongoMapper, it throws an error saying that errors is undefined function. So does it mean that this is simply not implemented in mongomapper / mongo driver ? Or is there some other clever way to do this that I could not figure ? Additional, 2 things here: - I following the exemple in the book to the line, so I was expecting to be able to use the console in sandbox mode, but apparently that does not work either: (...)ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/console/sandbox.rb:1:in `<top (required)>': uninitialized constant ActiveRecord (NameError) from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:226:in `initialize_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:153:in `load_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:26:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:8:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands.rb:23:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' Also, in the book they call "user" but I need to call "User" (note the capital U) why is that ? Is it like mangomapper does not follow the Ruby naming convention or something ? And finally, I am trying to validate the field email with a regex as shown in the tutorial. It does not throws any errors at the code, but whenever I try to insert it just won't ever accept it unless I comment out the :format option... class User include MongoMapper::Document key :name, String, :required => true, :length => { :maximum => 50 } key :email, String, :required => true, # :format => { :with => email_regex }, :uniqueness => { :case_sentitive => false} timestamps! end Any advices you can provide on those topics would help me a lot ! Thanks, Alex

  • ASP.net roles and Projects

    - by Zyphrax
    EDIT - Rewrote my original question to give a bit more information Background info At my work I'm working on a ASP.Net web application for our customers. In our implementation we use technologies like Forms authentication with MembershipProviders and RoleProviders. All went well until I ran into some difficulties with configuring the roles, because the roles aren't system-wide, but related to the customer accounts and projects. I can't name our exact setup/formula, because I think our company wouldn't approve that... What's a customer / project? Our company provides management information for our customers on a yearly (or other interval) basis. In our systems a customer/contract consists of: one Account: information about the Company per Account, one or more Products: the bundle of management information we'll provide per Product, one or more Measurements: a period of time, in which we gather and report the data Extranet site setup Eventually we want all customers to be able to access their management information with our online system. The extranet consists of two sites: Company site: provides an overview of Account information and the Products Measurement site: after selecting a Measurement, detailed information on that period of time The measurement site is the most interesting part of the extranet. We will create submodules for new overviews, reports, managing and maintaining resources that are important for the research. Our Visual Studio solution consists of a number of projects. One web application named Portal for the basis. The sites and modules are virtual directories within that application (makes it easier to share MasterPages among things). What kind of roles? The following users (read: roles) will be using the system: Admins: development users :) (not customer related, full access) Employees: employees of our company (not customer related, full access) Customer SuperUser: top level managers (full access to their account/measurement) Customer ContactPerson: primary contact (full access to their measurement(s)) Customer Manager: a department manager (limited access, specific data of a measurement) What about ASP.Net users? The system will have many ASP.Net users, let's focus on the customer users: Users are not shared between Accounts SuperUser X automatically has access to all (and new) measurements User Y could be Primary contact for Measurement 1, but have no role for Measurement 2 User Y could be Primary contact for Measurement 1, but have a Manager role for Measurement 2 The department managers are many individual users (per Measurement), if Manager Z had a login for Measurement 1, we would like to use that login again if he participates in Measurement 2. URL structure These are typical urls in our application: http://host/login - the login screen http://host/project - the account/product overview screen (measurement selection) http://host/project/1000 - measurement (id:1000) details http://host/project/1000/planning - planning overview (for primary contact/superuser) http://host/project/1000/reports - report downloads (manager department X can only access report X) We will also create a document url, where you can request a specific document by it's GUID. The system will have to check if the user has rights to the document. The document is related to a Measurement, the User or specific roles have specific rights to the document. What's the problem? (finally ;)) Roles aren't enough to determine what a user is allowed to see/access/download a specific item. It's not enough to say that a certain navigation item is accessible to Managers. When the user requests Measurement 1000, we have to check that the user not only has a Manager role, but a Manager role for Measurement 1000. Summarized: How can we limit users to their accounts/measurements? (remember superusers see all measurements, some managers only specific measurements) How can we apply roles at a product/measurement level? (user X could be primarycontact for measurement 1, but just a manager for measurement 2) How can we limit manager access to the reports screen and only to their department's reports? All with the magic of asp.net classes, perhaps with a custom roleprovider implementation.

  • image processing algorithm in MATLAB

    - by user261002
    I am trying to reconstruct an algorithm belong to this paper: Decomposition of biospeckle images in temporary spectral bands Here is an explanation of the algorithm: We recorded a sequence of N successive speckle images with a sampling frequency fs. In this way it was possible to observe how a pixel evolves through the N images. That evolution can be treated as a time series and can be processed in the following way: Each signal corresponding to the evolution of every pixel was used as input to a bank of filters. The intensity values were previously divided by their temporal mean value to minimize local differences in reflectivity or illumination of the object. The maximum frequency that can be adequately analyzed is determined by the sampling theorem and s half of sampling frequency fs. The latter is set by the CCD camera, the size of the image, and the frame grabber. The bank of filters is outlined in Fig. 1. In our case, ten 5° order Butterworth11 filters were used, but this number can be varied according to the required discrimination. The bank was implemented in a computer using MATLAB software. We chose the Butter-worth filter because, in addition to its simplicity, it is maximally flat. Other filters, an infinite impulse response, or a finite impulse response could be used. By means of this bank of filters, ten corresponding signals of each filter of each temporary pixel evolution were obtained as output. Average energy Eb in each signal was then calculated: where pb(n) is the intensity of the filtered pixel in the nth image for filter b divided by its mean value and N is the total number of images. In this way, en values of energy for each pixel were obtained, each of hem belonging to one of the frequency bands in Fig. 1. With these values it is possible to build ten images of the active object, each one of which shows how much energy of time-varying speckle there is in a certain frequency band. False color assignment to the gray levels in the results would help in discrimination. and here is my MATLAB code base on that : clear all for i=0:39 str = num2str(i); str1 = strcat(str,'.mat'); load(str1); D{i+1}=A; end new_max = max(max(A)); new_min = min(min(A)); for i=20:180 for j=20:140 ts = []; for k=1:40 ts = [ts D{k}(i,j)]; %%% kth image pixel i,j --- ts is time series end ts = double(ts); temp = mean(ts); ts = ts-temp; ts = ts/temp; N = 5; % filter order W = [0.00001 0.05;0.05 0.1;0.1 0.15;0.15 0.20;0.20 0.25;0.25 0.30;0.30 0.35;0.35 0.40;0.40 0.45;0.45 0.50]; N1 = 5; for ind = 1:10 Wn = W(ind,:); [B,A] = butter(N1,Wn); ts_f(ind,:) = filter(B,A,ts); end for ind=1:10 imag_test1{ind}(i,j) =sum((ts_f(ind,:)./mean(ts_f(ind,:))).^2); end end end for i=1:10 temp_imag = imag_test1{i}(:,:); x=isnan(temp_imag); temp_imag(x)=0; temp_imag=medfilt2(temp_imag); t_max = max(max(temp_imag)); t_min = min(min(temp_imag)); temp_imag = (temp_imag-t_min).*(double(new_max-new_min)/double(t_max-t_min))+double(new_min); imag_test2{i}(:,:) = temp_imag; end for i=1:10 A=imag_test2{i}(:,:); B=A/max(max(A)); B=histeq(B); figure,imshow(B) colorbar end but I am not getting the same result as paper. has anybody has aby idea why? or where I have gone wrong?

  • Access 2007 VBA & SQL - Update a Subform pointed at a dynamically created query

    - by Lucretius
    Abstract: I'm using VB to recreate a query each time a user selects one of 3 options from a drop down menu, which appends the WHERE clause If they've selected anything from the combo boxes. I then am attempting to get the information displayed on the form to refresh thereby filtering what is displayed in the table based on user input. 1) Dynamically created query using VB. Private Sub BuildQuery() ' This sub routine will redefine the subQryAllJobsQuery based on input from ' the user on the Management tab. Dim strQryName As String Dim strSql As String ' Main SQL SELECT statement Dim strWhere As String ' Optional WHERE clause Dim qryDef As DAO.QueryDef Dim dbs As DAO.Database strQryName = "qryAllOpenJobs" strSql = "SELECT * FROM tblOpenJobs" Set dbs = CurrentDb ' In case the query already exists we should deleted it ' so that we can rebuild it. The ObjectExists() function ' calls a public function in GlobalVariables module. If ObjectExists("Query", strQryName) Then DoCmd.DeleteObject acQuery, strQryName End If ' Check to see if anything was selected from the Shift ' Drop down menu. If so, begin the where clause. If Not IsNull(Me.cboShift.Value) Then strWhere = "WHERE tblOpenJobs.[Shift] = '" & Me.cboShift.Value & "'" End If ' Check to see if anything was selected from the Department ' drop down menu. If so, append or begin the where clause. If Not IsNull(Me.cboDepartment.Value) Then If IsNull(strWhere) Then strWhere = strWhere & " AND tblOpenJobs.[Department] = '" & Me.cboDepartment.Value & "'" Else strWhere = "WHERE tblOpenJobs.[Department] = '" & Me.cboDepartment.Value & "'" End If End If ' Check to see if anything was selected from the Date ' field. If so, append or begin the Where clause. If Not IsNull(Me.txtDate.Value) Then If Not IsNull(strWhere) Then strWhere = strWhere & " AND tblOpenJobs.[Date] = '" & Me.txtDate.Value & "'" Else strWhere = "WHERE tblOpenJobs.[Date] = '" & Me.txtDate.Value & "'" End If End If ' Concatenate the Select and the Where clause together ' unless all three parameters are null, in which case return ' just the plain select statement. If IsNull(Me.cboShift.Value) And IsNull(Me.cboDepartment.Value) And IsNull(Me.txtDate.Value) Then Set qryDef = dbs.CreateQueryDef(strQryName, strSql) Else strSql = strSql & " " & strWhere Set qryDef = dbs.CreateQueryDef(strQryName, strSql) End If End Sub 2) Main Form where the user selects items from combo boxes. picture of the main form and sub form http://i48.tinypic.com/25pjw2a.png 3) Subform pointed at the query created in step 1. Chain of events: 1) User selects item from drop down list on the main form. 2) Old query is deleted, new query is generated (same name). 3) Subform pointed at query does not update, but if you open the query by itself the correct results are displayed. Name of the Query: qryAllOpenJobs name of the subform: subQryAllOpenJobs Also, the Row Source of subQryAllOpenJobs = qryAllOpenJobs Name of the main form: frmManagement
