• TDC: The Developer's Conference Day One

  - by Tori Wieldt

  The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!New this year at TDC is the Java University track, sponsored by Oracle.  It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!" At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.Brazilian developers that cannot attend TDC can watch live streaming.

• Checking who is connected to your server, with PowerShell.

  - by Fatherjack

  There are many occasions when, as a DBA, you want to see who is connected to your SQL Server, along with how they are connecting and what sort of activities they are carrying out. I’m going to look at a couple of ways of getting this information and compare the effort required and the results achieved of each. SQL Server comes with a couple of stored procedures to help with this sort of task – sp_who and its undocumented counterpart sp_who2. There is also the pumped up version of these called sp_whoisactive, written by Adam Machanic which does way more than these procedures. I wholly recommend you try it out if you don’t already know how it works. When it comes to serious interrogation of your SQL Server activity then it is absolutely indispensable. Anyway, back to the point of this blog, we are going to look at getting the information from sp_who2 for a remote server. I wrote this Powershell script a week or so ago and was quietly happy with it for a while. I’m relatively new to Powershell so forgive both my rather low threshold for entertainment and the fact that something so simple is a moderate achievement for me. $Server = 'SERVERNAME' $SMOServer = New-Object Microsoft.SQLServer.Management.SMO.Server $Server # connection and query stuff         $ConnectionStr = "Server=$Server;Database=Master;Integrated Security=True" $Query = "EXEC sp_who2" $Connection = new-object system.Data.SQLClient.SQLConnection $Table = new-object "System.Data.DataTable" $Connection.connectionstring = $ConnectionStr try{ $Connection.open() $Command = $Connection.CreateCommand() $Command.commandtext = $Query $result = $Command.ExecuteReader() $Table.Load($result) } catch{ # Show error $error[0] | format-list -Force } $Title = "Data access processes (" + $Table.Rows.Count + ")" $Table | Out-GridView -Title $Title $Connection.close() So this is pretty straightforward, create an SMO object that represents our chosen server, define a connection to the database and a table object for the results when we get them, execute our query over the connection, load the results into our table object and then, if everything is error free display these results to the PowerShell grid viewer. The query simply gets the results of ‘EXEC sp_who2′ for us. Depending on how many connections there are will influence how long the query runs. The grid viewer lets me sort and search the results so it can be a pretty handy way to locate troublesome connections. Like I say, I was quite pleased with this, it seems a pretty simple script and was working well for me, I have added a few parameters to control the output and give me more specific details but then I see a script that uses the $SMOServer object itself to provide the process information and saves having to define the connection object and query specifications. $Server = 'SERVERNAME' $SMOServer = New-Object Microsoft.SQLServer.Management.SMO.Server $Server $Processes = $SMOServer.EnumProcesses() $Title = "SMO processes (" + $Processes.Rows.Count + ")" $Processes | Out-GridView -Title $Title Create the SMO object of our server and then call the EnumProcesses method to get all the process information from the server. Staggeringly simple! The results are a little different though. Some columns are the same and we can see the same basic information so my first thought was to which runs faster – so that I can get my results more quickly and also so that I place less stress on my server(s). PowerShell comes with a great way of testing this – the Measure-Command function. All you have to do is wrap your piece of code in Measure-Command {[your code here]} and it will spit out the time taken to execute the code. So, I placed both of the above methods of getting SQL Server process connections in two Measure-Command wrappers and pressed F5! The Powershell console goes blank for a while as the code is executed internally when Measure-Command is used but the grid viewer windows appear and the console shows this. You can take the output from Measure-Command and format it for easier reading but in a simple comparison like this we can simply cross refer the TotalMilliseconds values from the two result sets to see how the two methods performed. The query execution method (running EXEC sp_who2 ) is the first set of timings and the SMO EnumProcesses is the second. I have run these on a variety of servers and while the results vary from execution to execution I have never seen the SMO version slower than the other. The difference has varied and the time for both has ranged from sub-second as we see above to almost 5 seconds on other systems. This difference, I would suggest is partly due to the cost overhead of having to construct the data connection and so on where as the SMO EnumProcesses method has the connection to the server already in place and just needs to call back the process information. There is also the difference in the data sets to consider. Let’s take a look at what we get and where the two methods differ Query execution method (sp_who2) SMO EnumProcesses Description - Urn What looks like an XML or JSON representation of the server name and the process ID SPID Spid The process ID Status Status The status of the process Login Login The login name of the user executing the command HostName Host The name of the computer where the  process originated BlkBy BlockingSpid The SPID of a process that is blocking this one DBName Database The database that this process is connected to Command Command The type of command that is executing CPUTime Cpu The CPU activity related to this process DiskIO - The Disk IO activity related to this process LastBatch - The time the last batch was executed from this process. ProgramName Program The application that is facilitating the process connection to the SQL Server. SPID1 - In my experience this is always the same value as SPID. REQUESTID - In my experience this is always 0 - Name In my experience this is always the same value as SPID and so could be seen as analogous to SPID1 from sp_who2 - MemUsage An indication of the memory used by this process but I don’t know what it is measured in (bytes, Kb, Mb…) - IsSystem True or False depending on whether the process is internal to the SQL Server instance or has been created by an external connection requesting data. - ExecutionContextID In my experience this is always 0 so could be analogous to REQUESTID from sp_who2. Please note, these are my own very brief descriptions of these columns, detail can be found from MSDN for columns in the sp_who results here http://msdn.microsoft.com/en-GB/library/ms174313.aspx. Where the columns are common then I would use that description, in other cases then the information returned is purely for interpretation by the reader. Rather annoyingly both result sets have useful information that the other doesn’t. sp_who2 returns Disk IO and LastBatch information which is really useful but the SMO processes method give you IsSystem and MemUsage which have their place in fault diagnosis methods too. So which is better? On reflection I think I prefer to use the sp_who2 method primarily but knowing that the SMO Enumprocesses method is there when I need it is really useful and I’m sure I’ll use it regularly. I’m OK with the fact that it is the slower method because Measure-Command has shown me how close it is to the other option and that it really isn’t a large enough margin to matter.

• List of fonts containing selected character

  - by ShreevatsaR

  On Mac OS X, the Character Viewer (equivalent to Character Map on Ubuntu) has a feature where, when looking at a certain character, it can show a list of all fonts that contain that character. Is there something equivalent on Ubuntu? The use case is that, for instance, I could click on a Kannada character and see all fonts that cover that character (and presumably, the rest of the Kannada language range).

  - by techno

  I have found certain shareware software products have large number of downloads. My question is if there are some 20,000 free downloads, how many of the downloaders would have actually bought and paid for this software? For Conversion sake consider the FastStone Image viewer which is actually free http://www.faststone.org/FSResizerDetail.htm but what could it earn if it was charged 30$ and about 10,000 downloads.

• Syntax error in Maya Python Script [on hold]

  - by Enchanter

  Ok this error is immensly frustrating as it is obviously a simple syntax issue. Basically I've written two lines of maya script in python designed to create a list of the names of all the joints of a model currently selected in the model viewer. Here are the two lines of script: import maya.cmds joints = ls(selection = true, type = 'joint') Upon compiling the code the script editor is saying there is a syntax error in the second line, but I do not see any reason why this code should not execute?

• Trash Destination Adapter

  The Trash Destination and this article came from early experiences of using SSIS and community feedback at the time. When developing a package it is very useful to have a destination adapter that does nothing but consume rows with no setup requirement. You often want run a package part way through development, or just add a path so you can set a Data Viewer. There are stock tasks that can be used, but with the Trash Destination all columns are treated as selected automatically (usage type of read-only), so the pipeline knows they are required.

• view switcher in window

  - by RhZ

  I used to have button in my file viewer window that allowed me to easily change from list to compact to icons, which was really convenient. Now, in 12.04 (running gnome fallback mode to mostly keep my original layout) I don't have that anymore, I have to go to 'view' and then at the bottom of the menu choose the way I want to display the files. Any way to get this switcher back? In its place I just have a search function and buttons that I don't need and never use.

• Ubuntu Server running VNC

  - by xwapilot

  I have access to four computers: 1 Ubuntu Server desktop (Version 10.04) 1 Mac Mini (Snow Leopard) 1 Windows desktop (Windows 7) 1 Windows laptop (Windows Vista) The first three will always be on the home network. My goal is to SSH from the laptop into the server and be able, through VNC (or another remote desktop software), to control the windows and mac computers. The goal of this would be a slightly heightened network security over using VNC to directly access the mac or windows desktop. I have successfully used SSH to connect to the server, but have not been able to successfully implement the remote desktop connection. I would appreciate help doing so. Here's what I've done so far: As per instructions here: http://www.stuartellis.eu/articles/vnc-on-linux/ I installed the following: vnc4server – the main VNC server software vnc-java – enables access from Web browsers with Java support xvnc4viewer – a basic VNC viewer I then set up a password using the vncpasswd command. To attempt to connect to the mac, I followed directions I found in a thread at superuser. com and went to "System PreferencesSharing" and enabled "Screen Sharing". Subsequently, I tried entering the following commands into Ubuntu: vncviewer mac_ip_address::5904 vncviewer mac_ip_address:0 vncviewer mac_ip_address:1 They all returned the following: VNC Viewer Free Edition 4.1.1 for X - built Apr 9 2010 18:41:55 Copyright (C) 2002-2005 RealVNC Ltd. See http ://www .realvnc. com for information on VNC. vncviewer: unable to open display "" I'm sure I'm missing something important, but I'm not sure what it is. Do I need to have a GUI installed, or did that come with the vnc packages I installed?

• VPN Error 691 but server says authenticated on server

  - by Andy

  Hello all, I have a problem with a vpn connection on Windows XP SP3 that appears to be related to an account (maybe privilleges or an option that I have missed). When connecting using my account, which is a domain administrator account it will connect to through the vpn fine. However, using an account created for another person they receive Error 691: Username or Password is not valid for this domain. On the domain controller (windows 2003) I see a logon successful message: User DOMAIN\user was granted access. Fully-Qualified-User-Name = int.company.net.au/People/Management/User NAS-IP-Address = 10.30.0.3 NAS-Identifier = not present Client-Friendly-Name = MelbourneCore Client-IP-Address = Router-ip Calling-Station-Identifier = not present NAS-Port-Type = Virtual NAS-Port = 77 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = undetermined Policy-Name = Remote VPN Access Authentication-Type = MS-CHAPv1 EAP-Type = Does anyone have any ideas as to where else I should look for finding a solution? If i use the wrong password it gives a logon failure error in the event viewer. Also removing them from the remote access group gives a logon failure error. Nothing appears in the event viewer on the local machine. In the past all that is required is to add them into our Remote Access Users group. Any help?

• Does Windows 7 Authenticate Cached Credentials on Startup

  - by Farray

  Problem I have a Windows domain user account that gets automatically locked-out semi-regularly. Troubleshooting Thus Far The only rule on the domain that should automatically lock an account is too many failed login attempts. I do not think anyone nefarious is trying to access my account. The problem started occurring after changing my password so I think it's a stored credential problem. Further to that, in the Event Viewer's System log I found Warnings from Security-Kerberos that says: The password stored in Credential Manager is invalid. This might be caused by the user changing the password from this computer or a different computer. To resolve this error, open Credential Manager in Control Panel, and reenter the password for the credential mydomain\myuser. I checked the Credential Manager and all it has are a few TERMSRV/servername credentials stored by Remote Desktop. I know which stored credential was incorrect, but it was stored for Remote Desktop access to a specific machine and was not being used (at least not by me) at the time of the warnings. The Security-Kerberos warning appears when the system was starting up (after a Windows Update reboot) and also appeared earlier this morning when nobody was logged into the machine. Clarification after SnOrfus answer: There was 1 set of invalid credentials that was stored for a terminal server. The rest of the credentials are known to be valid (used often & recently without issues). I logged on to the domain this morning without issue. I then ran windows update which rebooted the computer. After the restart, I couldn't log in (due to account being locked out). After unlocking & logging on to the domain, I checked Event Viewer which showed a problem with credentials after restarting. Since the only stored credentials (according to Credential Manager) are for terminal servers, why would there be a Credential problem on restart when remote desktop was not being used? Question Does anyone know if Windows 7 "randomly" checks the authentication of cached credentials?
