  • How to extract frequency information from samples from PortAudio using FFTW in C

    - by houbysoft
    Hi all, I want to make a program that would record audio data using PortAudio (I have this part done) and then display the frequency information of that recorded audio (for now, I'd like to display the average frequency of each of the group of samples as they come in). From some research I've done, I know that I need to do an FFT. So I googled for a library to do that, in C, and found FFTW. However, now I am a little lost. What exactly am I supposed to do with the samples I recorded to extract some frequency information from them? What kind of FFT should I use (I assume I'd need a real data 1D?)? And once I'd do the FFT, how do I get the frequency information from the data it gives me? Thanks a lot in advance.

  • saving information in file in php

    - by Mac Taylor
    hey guys i want to write a tracking system and now i can save in my Mysql database . but saving information about each ip that visits is a huge work for mysql so i think if i could save the information in a file , then there is no discussion about database and its problems . but to begin this : i realy dont know how to save in a file in a way that i can read it with no problem and show the details this is what is used to insert into my database sql_query("insert into tracking (date_time, ip_address, hostname,referer, page , page_title) values ('".sql_quote($dt)."', '".sql_quote($ipaddr)."', '".sql_quote($hostnm)."','$referer', '".sql_quote($pg)."', '".sql_quote($pagetitle)."')", $dbi); i need to show information about all ips in rows , after saving in a file what should i do to save and show in row order ( table ) php/mysql

  • IIS log analysis - how to retrieve referer information

    - by balalakshmi
    Per this documentation http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/676400bc-8969-4aa7-851a-9319490a9bbb.mspx?mfr=true , it says cs(Referrer) contains the referer information that can be read from the IIS log I am trying to display the log information using a asp.net repeater control: <asp:Repeater ID="rptlIISLogEntries" runat="server"> ... ... <ItemTemplate> <tr> <td><%# Eval("time")%></td> <td><%# Eval("cs(Referrer)")%></td> Eval("cs(Referrer)" throws an error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'cs'. my Question: how to display the referer information in the repeater

  • Get Hardware Information for HWs that is not installed

    - by Isaac
    I am pretty sure how to retrieve hardware information with WMI classes. but WMIs have a big limitation: They Just can get information for installed hardwares. I need to retrieve information about CPU (model,speed,etc..),Video Card, Sound Card, USB Ports, etc. I found a really good software (HWiNFO) that can do this even the drivers for hardware parts is not installed. It seems that HWiNFO uses a internal database to give a name for each hardware part. So is there any free library/DLL/component that can do this in Windows XP or higher Note: Although HWiNFO SDK seems good, it's not free. So it doesn't exist! ;) I need a free library.

  • Android 2.3.3 - Messages: Wrong Status Information in the Conversation Overview

    - by Thomas Hoffmann
    On my HTC Desire Z with Android 2.3.3 I get from time to time the problem, that the status information ist wrong. That means status information says, that there is an unread, unsent or failed SMS, but this SMS is already deleted. Does anybody know, where I can reset this information? It must be stored anywhere in ContentResolver of content://mms-sms/conversations or content://sms/conversations on the thread-level, but I have no idea. Example: After I deleted a number of failed SMS in the non delivered SMS overview, the status of non delivered SMS was not reset in the Messages conversation overview though in each conversation there wasn't any undelivered SMS left.

  • Accepting bank account information in a form

    - by jeffthink
    What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

  • How to get site context/information during the PreapplicationStartMethod

    - by Mike
    When you run the same web based application as a multi-tenant application for different clients is there a way during the PreapplicationStartMethod to gain some kind of context to the site that is being started? More specifically I'd like to get the host header information (the "bindingInformation" attribute value from the applicationHost.config); I have found ways to get this information at the time of a specific request long after the application has started. Is there a way to get the information during the application startup process? This is an MVC 3 application and IIS 7.5.

  • Information sent in an HTML form

    - by dedalo
    Hi, I've a HTML file that shows to the user the contents of a database (it is shown as a table). The user can choose one of the rows.When this is done the selection made by the user is sent to a servlet that will work with that information. Imagine that this servlet is going to look for files related to the information chosen by the user. What I'd like to do is to provide the user with the option of also choosing the number of files that are going to be looked for by the servlet. That way the user should be able to choose one of the rows shown in the table and should also be able of typing the numers of files that are to be looked for. So far I'm able to send to the servlet what the user chooses in the table, but I'd like to know if it is possible to attach to this information the number of files requested. Thanks

  • does it make sense to send password information during email communication from websites

    - by Samuel
    Most of the online sites on registration do send a link to activate the site and on any further correspondence with the end user they provide information about the site and also provide the login credentials with password in clear text (as given below) Username - [email protected] Password - mysecretpassword What would you do in such a case? From a usability perspective does it make sense to send the password information in clear text or should you just avoid sending this information. I was under the impression that most of the passwords are MD5 hashed before storing in the database and hence the service provider will not have any access to clear text passwords, is this a security violation?

  • Pass information back from an iframe?

    - by ThinkBohemian
    Right now i'm building a firefox plugin that duplicates some functionality on my website. It takes in an email address and then returns information to the user. The easiest way to do this in the plugin is to use an Iframe and render that super simple form on my website. All of this works great, but to make the plugin really useful, i would like the plugin to have access to the information that the iframe renders, so it can use it in the current window that the user is in. Is it possible to pass information back through an Iframe in this manner? I know there are quite a few domain access restrictions with Iframes, so any help or insight is appreciated!!

  • Automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? Let me know if any more information is needed.

  • Can an XML prolog contain custom information?

    - by DaveJohnston
    Is it legal to add additional custom information somewhere in an XML prolog? For example, in my case, I would like to add an indicator of which serialiser version was used to create the XML, so that clients receiving the XML could automatically select the correct corresponding de-serialiser. I could add the information as an attribute of the root tag, but I thought it would be cleaner to add the information in the prolog, like the standard XML version: <?xml version="1.0"?> something like: <?serialiser version="1.0"?> or is the prolog reserved purely for those things specified by W3C?

  • Where do you hang your semantic information, html?

    - by bobobobo
    Well, I keep putting semantic information about what an element means for the page logically in the class attribute <li class="phone-number">555-5555</li> It seems to work for this dual purpose of hanging semantic information and a pointer to how to style it. I'm not sure if this is the best idea, I'm trying to see if others have other ways of doing it. I also started to use a hidden input: <li>555-5555 <input class="semantics" type="hidden" value="phone-number" /></li> inside an element, so with jQuery, I can retrieve additional information about the element using li.find( '.semantics' ).val() To get an element's semantics from JavaScript

  • php/mysql question, retrieving information

    - by chance
    Hey SO, I have a question, pretty new at PHP and MySql but was curious is it possible to display only the most recent column to a table, from a database? I know it is possible to display a list of all information, or if you have just one column of information in your table to display that using the Here is my code for my basic script (just loads 1 column of information) I would like it to only print out the recent column i added to the table $con = mysql_connect ("localhost","username","password"); if (!$con) { die ('Could not connect:' . mysql_error()0; } mysql_select_db("db_name", $con); $result = mysql_query(Select column FROM table"); while($row = mysql_fetch_array($result)) { echo $row['column']; } mysql_close($con); * keep in mind, im not looking for someone to shoot me my code with it completed, though it would be handy, however just giving me the options of what I have to do, or what the script is called would be plentiful enough for my research, thanks!

  • Authority Information Access local path being ignored

    - by Kevin
    I have a CA set up in Server 2008 R2, and generally it is working, but I can't control the local path/filename it writes its own certificate to for the Authority Information Access publishing. Here's a screen shot of the dialog I'm trying to set this on: From these settings I would expect to get the file: C:\Windows\system32\CertSrv\CertEnroll\DAMNIT.crt But instead I get: C:\Windows\system32\CertSrv\CertEnroll\SERVER.domain.com_My Issuing Authority(1).crt Of course, the actual change shown wouldn't be very useful, but it's illustrative; no matter what path/filename I use, it always lands up in the same place and with the same name. I actually wanted to change the name from <ServerDNSName>_<CaName><CertificateName>.crt to <CaName><CertificateName>.crt, since the latter corresponds to the HTTP URL whereas the former does not. Admittedly, I haven't set up many CAs so perhaps I'm just deluded as to what this dialog is supposed to be setting, but if so this is notoriously bad UI design. (Incidentally, I have a couple other complaints with the same dialog.) What's going on here and is there some way to get the filename pattern I want?

  • Need a place to store a few bytes of meta information on storage media

    - by Jason C
    I'm working on an embedded project. I need a place to store some filesystem-independent meta information on a storage device. The device has an MSDOS partition table. The device also may have unallocated space (depending on its size) but it will be TRIMmed (and also may be blown away by new partitions in the future). I need a location on the device that is not unallocated and that has a low risk of being touched (outside of completely erasing the device). The device is only guaranteed to have an MBR at the point the meta data needs to first be written; meaning there are no EBRs/VBRs present that I could use. There are 446 bytes at the very start of the device available for MBR bootstrap code. Currently my only idea is to store data at the end of this block. However, the device is bootable and I have no way of knowing if I'd be blowing away bootstrap code or not. The sector size is 512 bytes and the MBR is the first sector, I'm pretty sure (correct me if I'm wrong) that that means the second sector is available for use by partition data, so I can't use that either. Does anybody have any ideas? I need 4 bytes of space.

  • Attempting to ping RPC endpoint 6001/6004 (Exchange Information Store) on server on Exchange2010

    - by MadBoy
    I have Exchange 2010 in hosting setup like: TMG 2010 as load balancer Exchange 2010 x 2 (CAS,MAILBOX,HUB on each server) AD1, AD2 machines File witness All people currently connect thru OWA or POP3/SMTP and that works fine. The problem is autodiscovery doesn't work and RPC in terms of setting up Outlook doesn't work too. It doesn't work if I am connected with VPN or not. The thing is it used to work. Before reinstall of my machine 2 days ago I was able to get mails successfully thru Outlook that was set up using autodiscovery (but I was getting reports setting up of new clients wasn't working - so not sure why my outlook continued to work). I used https://www.testexchangeconnectivity.com to track it down and basically the message is more or less this: Attempting to ping RPC endpoint 6004 (NSPI Proxy Interface) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. I tried different solutions like disabling IP v6, followed couple of links and did all they proposed and it's still at the very same point: C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" I followed (and few others): http://helewix.com/blog/index.php/Microsoft-Solutions/2011/02/10/exchange-2010-how-to-open-ports-6001-6002-and-6004-on-your-server-for-telnet-to-work-and-rpc-to-be-able-to-connect-2 http://blogs.technet.com/b/exchange/archive/2008/06/20/3405633.aspx http://messagexchange.blogspot.com/2008/12/outlook-anywhere-failing-rpc-end-points.html Although most relate to Exchange 2007 and I have Exchange 2010 but there's not much things I can find on Exchange 2010 for the current problem. After applying all of those solutions error 6004 changed into error 6001 which doesn't bring me to my problems any closer. At this point even thou error was 6001 and 6004 was no more the 6004 port was still closed while 6001 stayed open. Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" So I reverted back to square one. I suspect it's a problem with TMG but really can't be sure. I tried multiple combinations but all fail.

  • Database users in the Oracle Utilities Application Framework

    - by Anthony Shorten
    I mentioned the product database users fleetingly in the last blog post and they deserve a better mention. This applies to all versions of the Oracle Utilities Application Framework. The Oracle Utilities Application Framework uses up to three users initially as part of the base operations of the product. The type of database supported (the framework supports Oracle, IBM DB2 and Microsoft SQL Server) dictates the number of users used and their permissions. For publishing brevity I will outline what is available for the Oracle database and, in summary, mention where it differs for the other database supported. For Oracle database customers we ship three distinct database users: Administration User (SPLADM or CISADM by default) - This is the database user that actually owns the schema. This user is not used by the product to do any DML (Data Manipulation Language) SQL other than that is necessary for maintenance of the database. This database user performs all the DCL (Data Control Language) and DDL (Data Definition Language) against the database. It is typically reserved for Database Administration use only. Product Read Write User (SPLUSER or CISUSER by default) - This is the database user used by the product itself to execute DML (Data Manipulation Language) statements against the schema owned by the Administration user. This user has the appropriate read and write permission to objects within the schema owned by the Administration user. For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. Product Read User (SPLREAD or CISREAD by default) - This is the database that has read only permission to the schema owned by the Administration user. It is used for reporting or any part of the product or interface that requires read permissions to the database (for example, products that have ConfigLab and Archiving use this user for remote access). For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. You may notice the words by default in the list above. The values supplied with the installer are the default and can be changed to what the site standard or implementation wants to use (as long as they conform to the standards supported by the underlying database). You can even create multiples of each within the same database and pointing to same schema. To manage the permissions for the users, there is a utility provided with the installation (oragensec (Oracle), db2gensec (DB2) or msqlgensec (SQL Server)) that generates the security definitions for the above users. That can be executed a number of times for each schema to give users appropriate permissions. For example, it is possible to define more than one read/write User to access the database. This is a common technique used by implementations to have a different user per access mode (to separate online and batch). In fact you can also allocate additional security (such as resource profiles in Oracle) to limit the impact of specific users at the database. To facilitate users and permissions, in Oracle for example, we create a CISREAD role (read only role) and a CISUSER role (read write role) that can be allocated to the appropriate database user. When the security permissions utility, oragensec in this case, is executed it uses the role to determine the permissions. To give you a case study, my underpowered laptop has multiple installations on it of multiple products but I have one database. I create a different schema for each product and each version (with my own naming convention to help me manage the databases). I create individual users on each schema and run oragensec to maintain the permissions for each appropriately. It works fine as long I have setup the userids appropriately. This means: Creating the users with the appropriate roles. I use the common CISUSER and CISREAD role across versions and across Oracle Utilities Application Framework products. Just remember to associate the CISUSER role with the database user you want to use for read/write operations and the CISREAD role with the user you wish to use for the read only operations. The role is treated as a tag to indicate the oragensec utility which appropriate permissions to assign to the user. The utilities for the other database types essentially do the same, obviously using the technology available within those databases. Run oragensec against the read write user and read only user against the appropriate administration user (I will abbreviate the user to ADM user). This ensures the right permissions are allocated to the right users for the right products. To help me there, I use the same prefix on the user name for the same product. For example, my Oracle Utilities Application Framework V4 environment has the administration user set to FW4ADM and the associated FW4USER and FW4READ as the users for the product to use. For my MWM environment I used MWMADM for the administration user and MWMUSER and MWMREAD for my associated users. You get the picture. When I run oragensec (once for each ADM user), I know what other users to associate with it. Remember to rerun oragensec against the users if I run upgrades, service packs or database based single fixes. This assures that the users are in synchronization with the ADM user. As a side note, for those who do not understand the difference between DML, DCL and DDL: DDL (Data Definition Language) - These are SQL statements that define the database schema and the structures within. SQL Statements such as CREATE and DROP are examples of DDL SQL statements. DCL (Data Control Language) - These are the SQL statements that define the database level permissions to DDL maintained objects within the database. SQL Statements such as GRANT and REVOKE are examples of DCL SQL statements. DML (Database Manipulation Language) - These are SQL statements that alter the data within the tables. SQL Statements such as SELECT, INSERT, UPDATE and DELETE are examples of DML SQL statements. Hope this has clarified the database user support. Remember in Oracle Utilities Application Framework V4 we enhanced this by also supporting CLIENT_IDENTIFIER to allow the database to still use the administration user for the main processing but make the database session more traceable.

  • Is your team is a high-performing team?

    As a child I can remember looking out of the car window as my father drove along the Interstate in Florida while seeing prisoners wearing bright orange jump suits and prison guards keeping a watchful eye on them. The prisoners were taking part in a prison road gang. These road gangs were formed to help the state maintain the state highway infrastructure. The prisoner’s primary responsibilities are to pick up trash and debris from the roadway. This is a prime example of a work group or working group used by most prison systems in the United States. Work groups or working groups can be defined as a collection of individuals or entities working together to achieve a specific goal or accomplish a specific set of tasks. Typically these groups are only established for a short period of time and are dissolved once the desired outcome has been achieved. More often than not group members usually feel as though they are expendable to the group and some even dread that they are even in the group. "A team is a small number of people with complementary skills who are committed to a common purpose, performance goals, and approach for which they are mutually accountable." (Katzenbach and Smith, 1993) So how do you determine that a team is a high-performing team?  This can be determined by three base line criteria that include: consistently high quality output, the promotion of personal growth and well being of all team members, and most importantly the ability to learn and grow as a unit. Initially, a team can successfully create high-performing output without meeting all three criteria, however this will erode over time because team members will feel detached from the group or that they are not growing then the quality of the output will decline. High performing teams are similar to work groups because they both utilize a collection of individuals or entities to accomplish tasks. What distinguish a high-performing team from a work group are its characteristics. High-performing teams contain five core characteristics. These characteristics are what separate a group from a team. The five characteristics of a high-performing team include: Purpose, Performance Measures, People with Tasks and Relationship Skills, Process, and Preparation and Practice. A high-performing team is much more than a work group, and typically has a life cycle that can vary from team to team. The standard team lifecycle consists of five states and is comparable to a human life cycle. The five states of a high-performing team lifecycle include: Formulating, Storming, Normalizing, Performing, and Adjourning. The Formulating State of a team is first realized when the team members are first defined and roles are assigned to all members. This initial stage is very important because it can set the tone for the team and can ultimately determine its success or failure. In addition, this stage requires the team to have a strong leader because team members are normally unclear about specific roles, specific obstacles and goals that my lay ahead of them.  Finally, this stage is where most team members initially meet one another prior to working as a team unless the team members already know each other. The Storming State normally arrives directly after the formulation of a new team because there are still a lot of unknowns amongst the newly formed assembly. As a general rule most of the parties involved in the team are still getting used to the workload, pace of work, deadlines and the validity of various tasks that need to be performed by the group.  In this state everything is questioned because there are so many unknowns. Items commonly questioned include the credentials of others on the team, the actual validity of a project, and the leadership abilities of the team leader.  This can be exemplified by looking at the interactions between animals when they first meet.  If we look at a scenario where two people are walking directly toward each other with their dogs. The dogs will automatically enter the Storming State because they do not know the other dog. Typically in this situation, they attempt to define which is more dominating via play or fighting depending on how the dogs interact with each other. Once dominance has been defined and accepted by both dogs then they will either want to play or leave depending on how the dogs interacted and other environmental variables. Once the Storming State has been realized then the Normalizing State takes over. This state is entered by a team once all the questions of the Storming State have been answered and the team has been tested by a few tasks or projects.  Typically, participants in the team are filled with energy, and comradery, and a strong alliance with team goals and objectives.  A high school football team is a perfect example of the Normalizing State when they start their season.  The player positions have been assigned, the depth chart has been filled and everyone is focused on winning each game. All of the players encourage and expect each other to perform at the best of their abilities and are united by competition from other teams. The Performing State is achieved by a team when its history, working habits, and culture solidify the team as one working unit. In this state team members can anticipate specific behaviors, attitudes, reactions, and challenges are seen as opportunities and not problems. Additionally, each team member knows their role in the team’s success, and the roles of others. This is the most productive state of a group and is where all the time invested working together really pays off. If you look at an Olympic figure skating team skate you can easily see how the time spent working together benefits their performance. They skate as one unit even though it is comprised of two skaters. Each skater has their routine completely memorized as well as their partners. This allows them to anticipate each other’s moves on the ice makes their skating look effortless. The final state of a team is the Adjourning State. This state is where accomplishments by the team and each individual team member are recognized. Additionally, this state also allows for reflection of the interactions between team members, work accomplished and challenges that were faced. Finally, the team celebrates the challenges they have faced and overcome as a unit. Currently in the workplace teams are divided into two different types: Co-located and Distributed Teams. Co-located teams defined as the traditional group of people working together in an office, according to Andy Singleton of Assembla. This traditional type of a team has dominated business in the past due to inadequate technology, which forced workers to primarily interact with one another via face to face meetings.  Team meetings are primarily lead by the person with the highest status in the company. Having personally, participated in meetings of this type, usually a select few of the team members dominate the flow of communication which reduces the input of others in group discussions. Since discussions are dominated by a select few individuals the discussions and group discussion are skewed in favor of the individuals who communicate the most in meetings. In addition, Team members might not give their full opinions on a topic of discussion in part not to offend or create controversy amongst the team and can alter decision made in meetings towards those of the opinions of the dominating team members. Distributed teams are by definition spread across an area or subdivided into separate sections. That is exactly what distributed teams when compared to a more traditional team. It is common place for distributed teams to have team members across town, in the next state, across the country and even with the advances in technology over the last 20 year across the world. These teams allow for more diversity compared to the other type of teams because they allow for more flexibility regarding location. A team could consist of a 30 year old male Italian project manager from New York, a 50 year old female Hispanic from California and a collection of programmers from India because technology allows them to communicate as if they were standing next to one another.  In addition, distributed team members consult with more team members prior to making decisions compared to traditional teams, and take longer to come to decisions due to the changes in time zones and cultural events. However, team members feel more empowered to speak out when they do not agree with the team and to notify others of potential issues regarding the work that the team is doing. Virtual teams which are a subset of the distributed team type is changing organizational strategies due to the fact that a team can now in essence be working 24 hrs a day because of utilizing employees in various time zones and locations.  A primary example of this is with customer services departments, a company can have multiple call centers spread across multiple time zones allowing them to appear to be open 24 hours a day while all a employees work from 9AM to 5 PM every day. Virtual teams also allow human resources departments to go after the best talent for the company regardless of where the potential employee works because they will be a part of a virtual team all that is need is the proper technology to be setup to allow everyone to communicate. In addition to allowing employees to work from home, the company can save space and resources by not having to provide a desk for every team member. In fact, those team members that randomly come into the office can actually share one desk amongst multiple people. This is definitely a cost cutting plus given the current state of the economy. One thing that can turn a team into a high-performing team is leadership. High-performing team leaders need to focus on investing in ongoing personal development, provide team members with direction, structure, and resources needed to accomplish their work, make the right interventions at the right time, and help the team manage boundaries between the team and various external parties involved in the teams work. A team leader needs to invest in ongoing personal development in order to effectively manage their team. People have said that attitude is everything; this is very true about leaders and leadership. A team takes on the attitudes and behaviors of its leaders. This can potentially harm the team and the team’s output. Leaders must concentrate on self-awareness, and understanding their team’s group dynamics to fully understand how to lead them. In addition, always learning new leadership techniques from other effective leaders is also very beneficial. Providing team members with direction, structure, and resources that they need to accomplish their work collectively sounds easy, but it is not.  Leaders need to be able to effectively communicate with their team on how their work helps the company reach for its organizational vision. Conversely, the leader needs to allow his team to work autonomously within specific guidelines to turn the company’s vision into a reality.  This being said the team must be appropriately staffed according to the size of the team’s tasks and their complexity. These tasks should be clear, and be meaningful to the company’s objectives and allow for feedback to be exchanged with the leader and the team member and the leader and upper management. Now if the team is properly staffed, and has a clear and full understanding of what is to be done; the company also must supply the workers with the proper tools to achieve the tasks that they are asked to do. No one should be asked to dig a hole without being given a shovel.  Finally, leaders must reward their team members for accomplishments that they achieve. Awards could range from just a simple congratulatory email, a party to close the completion of a large project, or other monetary rewards. Managing boundaries is very important for team leaders because it can alter attitudes of team members and can add undue stress to the team which will force them to loose focus on the tasks at hand for the group. Team leaders should promote communication between team members so that burdens are shared amongst the team and solutions can be derived from hearing the opinions of multiple sources. This also reinforces team camaraderie and working as a unit. Team leaders must manage the type and timing of interventions as to not create an even bigger mess within the team. Poorly timed interventions can really deflate team members and make them question themselves. This could really increase further and undue interventions by the team leader. Typically, the best time for interventions is when the team is just starting to form so that all unproductive behaviors are removed from the team and that it can retain focus on its agenda. If an intervention is effectively executed the team will feel energized about the work that they are doing, promote communication and interaction amongst the group and improve moral overall. High-performing teams are very import to organizations because they consistently produce high quality output and develop a collective purpose for their work. This drive to succeed allows team members to utilize specific talents allowing for growth in these areas.  In addition, these team members usually take on a sense of ownership with their projects and feel that the other team members are irreplaceable.
