• Cisco ASA 5505 site to site IPSEC VPN won't route from multiple LANs

  - by franklundy

  Hi I've set up a standard site to site VPN between 2 ASA 5505s (using the wizard in ASDM) and have the VPN working fine for traffic between Site A and Site B on the directly connected LANs. But this VPN is actually to be used for data originating on LAN subnets that are one hop away from the directly connected LANs. So actually there is another router connected to each ASA (LAN side) that then route to two completely different LAN ranges, where the clients and servers reside. At the moment, any traffic that gets to the ASA that has not originated from the directly connected LAN gets sent straight to the default gateway, and not through the VPN. I've tried adding the additional subnets to the "Protected Networks" on the VPN, but that has no effect. I have also tried adding a static route to each ASA trying to point the traffic to the other side, but again this hasn't worked. Here is the config for one of the sites. This works for traffic to/from the 192.168.144.x subnets perfectly. What I need is to be able to route traffic from 10.1.0.0/24 to 10.2.0.0/24 for example.

• Configuring CESoPSN using Cisco MWR 2941

  - by Rayne

  I'm trying to configure CESoPSN on two Cisco MWR 2941 routers, but the alarm LED lights are always lit. My configuration is modeled after this sample configuration. My setup is as follows: On the Cisco MWRs, E1 0/5 is configured to be CESoPSN, E1 0/9 is configured to be CESoPSN (CAS mode), and E1 0/7 is configured to be SAToP. The two MWRs are connected to each other via the GigabitEthernet port 0/2. The GigE ports are configured as a vlan because the ports are L2 ports and cannot be assigned an IP address directly. The two Cisco MWRs are connected to a traffic simulator, i.e. the traffic simulator will play out E1 traffic to MWR 1 and record the output traffic from MWR 2. On my traffic simulator, when it's connected to the E1 ports 0/5 and 0/9 (both CESoPSN configurations), the "Remote" alarm is on. However, when connected to the E1 ports 0/7 (SAToP configuration), no alarms were on. The GigE connection seems to be working fine (both LED lights on the 2 ports are green). The SAToP configuration seems to be fine too (Left LED is green, right LED is off on both E1 0/7 ports). However, both CESoPSN configurations seem to be not working (Left LED is green, right LED is yellow on both E1 0/5 and 0/9 ports). I don't know if there's anything wrong with my configuration for the CESoPSN, as I'm very new to this. The relevant portions of the configuration are as follows: MWR 1: controller E1 0/5 clock source internal cem-group 5 timeslots 1-31 description E1 CESoPSN example ! controller E1 0/7 clock source internal cem-group 7 unframed description E1 SATOP example ! controller E1 0/9 mode cas clock source internal cem-group 9 timeslots 1-24 description E1 CESoPSN CAS example ! interface Loopback0 ip address 30.30.30.1 255.255.255.255 ! interface GigabitEthernet0/2 switchport access vlan 100 mpls ip ! interface CEM0/5 no ip address cem 5 xconnect 30.30.30.2 305 encapsulation mpls ! ! interface CEM0/7 no ip address cem 7 xconnect 30.30.30.2 307 encapsulation mpls ! ! interface CEM0/9 no ip address cem 9 signaling inband-cas xconnect 30.30.30.2 309 encapsulation mpls ! ! interface Vlan100 ip address 50.50.50.1 255.255.255.0 no ptp enable mpls ip ! no ip classless ip forward-protocol nd ip route 30.30.30.2 255.255.255.255 50.50.50.2 !

• Troubleshooting sudoers via ldap

  - by dafydd

  The good news is that I got sudoers via ldap working on Red Hat Directory Server. The package is sudo-1.7.2p1. I have some LDAP/Kerberos users in an LDAP group called wheel, and I have this entry in LDAP: # %wheel, SUDOers, example.com dn: cn=%wheel,ou=SUDOers,dc=example,dc=com cn: %wheel description: Members of group wheel have access to all privileges. objectClass: sudoRole objectClass: top sudoCommand: ALL sudoHost: ALL sudoUser: %wheel So, members of group wheel have administrative privileges via sudo. This has been tested and works fine. Now, I have this other sudo privilege set up to allow members of a group called Administrators to perform two commands as the non-root owner of those commands. # %Administrators, SUDOers, example.com dn: cn=%Administrators,ou=SUDOers,dc=example,dc=com sudoRunAsGroup: appGroup sudoRunAsUser: appOwner cn: %Administrators description: Allow members of the group Administrators to run various commands . objectClass: sudoRole objectClass: top sudoCommand: appStop sudoCommand: appStart sudoCommand: /path/to/appStop sudoCommand: /path/to/appStart sudoUser: %Administrators Unfortunately, members of Administrators are still refused permission to run appStart or appStop: -bash-3.2$ sudo /path/to/appStop [sudo] password for Aaron: Sorry, user Aaron is not allowed to execute '/path/to/appStop' as root on host.example.com. -bash-3.2$ sudo -u appOwner /path/to/appStop [sudo] password for Aaron: Sorry, user Aaron is not allowed to execute '/path/to/appStop' as appOwner on host.example.com. /var/log/secure shows me these two sets of messages for the two attempts: Oct 31 15:02:36 host sudo: pam_unix(sudo:auth): authentication failure; logname=Aaron uid=0 euid=0 tty=/dev/pts/3 ruser= rhost= user=Aaron Oct 31 15:02:37 host sudo: pam_krb5[1508]: TGT verified using key for 'host/[email protected]' Oct 31 15:02:37 host sudo: pam_krb5[1508]: authentication succeeds for 'Aaron' ([email protected]) Oct 31 15:02:37 host sudo: Aaron : command not allowed ; TTY=pts/3 ; PWD=/auto/home/Aaron ; USER=root ; COMMAND=/path/to/appStop Oct 31 15:02:52 host sudo: pam_unix(sudo:auth): authentication failure; logname=Aaron uid=0 euid=0 tty=/dev/pts/3 ruser= rhost= user=Aaron Oct 31 15:02:52 host sudo: pam_krb5[1547]: TGT verified using key for 'host/[email protected]' Oct 31 15:02:52 host sudo: pam_krb5[1547]: authentication succeeds for 'Aaron' ([email protected]) Oct 31 15:02:52 host sudo: Aaron : command not allowed ; TTY=pts/3 ; PWD=/auto/home/Aaron ; USER=appOwner; COMMAND=/path/to/appStop The questions: Does sudo have some sort of verbose or debug mode where I can actually watch it capture the sudoers privilege list and determine whether or not Aaron should have the privilege to run this command? (This question is probably independent of where the sudoers database is kept.) Does sudo work with some background mechanism that might have a log level I could turn up? Right now, I can't fix a problem I can't identify. Is this an LDAP search failure? Is this a group member matching failure? Identifying why the command fails will help me identify the fix... Next step: Recreate the privilege in /etc/sudoers, and see if it works locally... Cheers!

• How can I recover an ext4 filesystem corrupted after a fsck?

  - by Regan

  I have an ext4 filesystem on luks over software raid5. The filesystem was operating "just fine" for several years when I was beginning to run out of space. I had a 9T volume on 6x2T drives. I began upgrading to 3T drives by doing the mdadm fail, remove, add, rebuild, repeat process until I had a larger array. I then grew the luks container, and then when I unmounted and tried to resize2fs I was given the message the filesystem was dirty and needed e2fsck. Without thinking I just did e2fsck -y /dev/mapper/candybox and it began spewing all kinds of inode being removed type messages (can't remember exactly) I killed e2fsck and tried to remount the filesystem to backup data I was concerned about. When trying to mount at this point I get: # mount /dev/mapper/candybox /candybox mount: wrong fs type, bad option, bad superblock on /dev/mapper/candybox, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Looking back at my older logs I noticed the filesystem was giving this error each time the machine booted: kernel: [79137.275531] EXT4-fs (dm-2): warning: mounting fs with errors, running e2fsck is recommended So shame on me for not paying attention :( I then tried to mount using every backup superblock (one after another) and each attempt left this in my log: EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 0 failed (26534!=65440) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 1 failed (38021!=36729) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 2 failed (18336!=39845) ... EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 11911 failed (28743!=44098) BUG: soft lockup - CPU#0 stuck for 23s! [mount:2939] Attempts to restart e2fsck results in: # e2fsck /dev/mapper/candybox e2fsck 1.41.14 (22-Dec-2010) e2fsck: Group descriptors look bad... trying backup blocks... candy: recovering journal e2fsck: unable to set superblock flags on candy At this point, I decided it best to order some more drives and make an image using ddrescue Now two weeks later I have an image of the luks partition in a .img file. # ls -lh total 14T -rw-r--r-- 1 root root 14T Oct 25 01:57 candybox.img -rw-r--r-- 1 root root 271 Oct 20 14:32 candybox.logfile After numerous attempts using everything I could find online I could not coerce e2fsck to do anything on the image, so I used mkfs.ext4 -L candy candybox.img -m 0 -S and I was able to mount the dirty filesystem readonly without the journal and recover 960G of data. It gave all kinds of errors of various directories not existing and so forth but I was able to get some stuff. Which gave me some hope! I then ran e2fsck again and it had to recreate the root inode and gave a massive list of correcting group counts, I accepted the root inode creation and said no to everything else, leaving a completely empty filesystem. Re-ran again and said yes to all questions with the same result but now a "clean" but empty filesystem. extundelete gives me 0 recoverable inodes found. And now I'm stuck again, I can't come up with any other methods other than dropping to something like photorec which will give me an absolute mess with how large the filesystem was. I'm willing to re-copy the image from the original array and start over, if I can get any suggestions or ideas on a way to get more of my files back. I wish I could give more detailed logs of the commands that have run, but the output is long scrolled passed except for what gets logged to syslog and my memory is not as detailed due to the timeframe this has occurred over. Any help is greatly appreciated!

• Microsoft, please help me diagnose TFS Administration permission issues!

  - by Martin Hinshelwood

  I recently had a fun time trying to debug a permission issue I ran into using TFS 2010’s TfsConfig. Update 5th March 2010 – In its style of true excellence my company has added rant to its “Suggestions for Better TFS”. <rant> I was trying to run the TfsConfig tool and I kept getting the message: “TF55038: You don't have sufficient privileges to run this tool. Contact your Team Foundation system administrator." This message made me think that it was something to do with the Install permissions as it is always recommended to use a single account to do every install of TFS. I did not install the original TFS on our network and my account was not used to do the TFS2010 install. But I did do the upgrade from 2010 beta 2 to 2010 RC with my current account. So I proceeded to do some checking: Am I in the administrators group on the server? Figure: Yes, I am in the administrators group on the server Am I in the Administration Console users list? Figure: Yes, I am in the Administration Console users list Have I reapplied the permissions in the Administration Console users list ticking all the options? Figure: Make sure you check all of the boxed if you want to have all the admin options Figure: Yes, I have made sure that all my options are correct. Am I in the Team Foundation administrators group? Figure: Yes, I am in the Team Foundation Administrators group Is my account explicitly SysAdmin on the Database server? Figure: Yes, I do have explicit SysAdmin on the database Can you guess what the problem was? The command line window was not running as the administrator! As with most other applications there should be an explicit error message that states: "You are not currently running in administrator mode; please restart the command line with elevated privileges!" This would have saved me 30 minutes, although I agree that I should change my name to Muppet and just be done with it. </rant>   Technorati Tags: Visual Studio ALM,Administration,Team Foundation Server Admin Console,TFS Admin Console

• Sending Messages to SignalR Hubs from the Outside

  - by Ricardo Peres

  Introduction You are by now probably familiarized with SignalR, Microsoft’s API for real-time web functionality. This is, in my opinion, one of the greatest products Microsoft has released in recent time. Usually, people login to a site and enter some page which is connected to a SignalR hub. Then they can send and receive messages – not just text messages, mind you – to other users in the same hub. Also, the server can also take the initiative to send messages to all or a specified subset of users on its own, this is known as server push. The normal flow is pretty straightforward, Microsoft has done a great job with the API, it’s clean and quite simple to use. And for the latter – the server taking the initiative – it’s also quite simple, just involves a little more work. The Problem The API for sending messages can be achieved from inside a hub – an instance of the Hub class – which is something that we don’t have if we are the server and we want to send a message to some user or group of users: the Hub instance is only instantiated in response to a client message. The Solution It is possible to acquire a hub’s context from outside of an actual Hub instance, by calling GlobalHost.ConnectionManager.GetHubContext<T>(). This API allows us to: Broadcast messages to all connected clients (possibly excluding some); Send messages to a specific client; Send messages to a group of clients. So, we have groups and clients, each is identified by a string. Client strings are called connection ids and group names are free-form, given by us. The problem with client strings is, we do not know how these map to actual users. One way to achieve this mapping is by overriding the Hub’s OnConnected and OnDisconnected methods and managing the association there. Here’s an example: 1: public class MyHub : Hub 2: { 3: private static readonly IDictionary<String, ISet<String>> users = new ConcurrentDictionary<String, ISet<String>>(); 4:  5: public static IEnumerable<String> GetUserConnections(String username) 6: { 7: ISet<String> connections; 8:  9: users.TryGetValue(username, out connections); 10:  11: return (connections ?? Enumerable.Empty<String>()); 12: } 13:  14: private static void AddUser(String username, String connectionId) 15: { 16: ISet<String> connections; 17:  18: if (users.TryGetValue(username, out connections) == false) 19: { 20: connections = users[username] = new HashSet<String>(); 21: } 22:  23: connections.Add(connectionId); 24: } 25:  26: private static void RemoveUser(String username, String connectionId) 27: { 28: users[username].Remove(connectionId); 29: } 30:  31: public override Task OnConnected() 32: { 33: AddUser(this.Context.Request.User.Identity.Name, this.Context.ConnectionId); 34: return (base.OnConnected()); 35: } 36:  37: public override Task OnDisconnected() 38: { 39: RemoveUser(this.Context.Request.User.Identity.Name, this.Context.ConnectionId); 40: return (base.OnDisconnected()); 41: } 42: } As you can see, I am using a static field to store the mapping between a user and its possibly many connections – for example, multiple open browser tabs or even multiple browsers accessing the same page with the same login credentials. The user identity, as is normal in .NET, is obtained from the IPrincipal which in SignalR hubs case is stored in Context.Request.User. Of course, this property will only have a meaningful value if we enforce authentication. Another way to go is by creating a group for each user that connects: 1: public class MyHub : Hub 2: { 3: public override Task OnConnected() 4: { 5: this.Groups.Add(this.Context.ConnectionId, this.Context.Request.User.Identity.Name); 6: return (base.OnConnected()); 7: } 8:  9: public override Task OnDisconnected() 10: { 11: this.Groups.Remove(this.Context.ConnectionId, this.Context.Request.User.Identity.Name); 12: return (base.OnDisconnected()); 13: } 14: } In this case, we will have a one-to-one equivalence between users and groups. All connections belonging to the same user will fall in the same group. So, if we want to send messages to a user from outside an instance of the Hub class, we can do something like this, for the first option – user mappings stored in a static field: 1: public void SendUserMessage(String username, String message) 2: { 3: var context = GlobalHost.ConnectionManager.GetHubContext<MyHub>(); 4: 5: foreach (String connectionId in HelloHub.GetUserConnections(username)) 6: { 7: context.Clients.Client(connectionId).sendUserMessage(message); 8: } 9: } And for using groups, its even simpler: 1: public void SendUserMessage(String username, String message) 2: { 3: var context = GlobalHost.ConnectionManager.GetHubContext<MyHub>(); 4:  5: context.Clients.Group(username).sendUserMessage(message); 6: } Using groups has the advantage that the IHubContext interface returned from GetHubContext has direct support for groups, no need to send messages to individual connections. Of course, you can wrap both mapping options in a common API, perhaps exposed through IoC. One example of its interface might be: 1: public interface IUserToConnectionMappingService 2: { 3: //associate and dissociate connections to users 4:  5: void AddUserConnection(String username, String connectionId); 6:  7: void RemoveUserConnection(String username, String connectionId); 8: } SignalR has built-in dependency resolution, by means of the static GlobalHost.DependencyResolver property: 1: //for using groups (in the Global class) 2: GlobalHost.DependencyResolver.Register(typeof(IUserToConnectionMappingService), () => new GroupsMappingService()); 3:  4: //for using a static field (in the Global class) 5: GlobalHost.DependencyResolver.Register(typeof(IUserToConnectionMappingService), () => new StaticMappingService()); 6:  7: //retrieving the current service (in the Hub class) 8: var mapping = GlobalHost.DependencyResolver.Resolve<IUserToConnectionMappingService>(); Now all you have to do is implement GroupsMappingService and StaticMappingService with the code I shown here and change SendUserMessage method to rely in the dependency resolver for the actual implementation. Stay tuned for more SignalR posts!

• How to Disable Access to the Registry in Windows 7

  - by Mysticgeek

  If you don’t know what your doing in the Registry, you can mess up your computer pretty good. Today we show you how to prevent users from accessing the Registry and making any changes to it. Using Local Group Policy Editor Note: This method uses Group Policy Editor which is not available in Home versions of Windows. First type gpedit.msc into the Search box in the Start menu. When Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select System. Under Setting in the right panel double-click on Prevent access to registry editing tools. Select the radio button next to Enabled, click OK, then close out of Group Policy Editor. Now if a user tries to access the Registry… They will get the following message advising they cannot access it.   Using Registry Enabler & Disabler 3 If you’re using Home or Starter version of Windows 7, you can use a neat utility called Registry Enabler & Disabler (link below). This app works on XP and Vista as well. There is no installation involved so you can run it from a flash drive, disable the registry, then take the flash drive with you while a the user is on the machine.   Again, if the user tries to access the Registry they will get the following error… Using one of these options will stop users from gaining access to the Registry or running any registry hacks. Of course if you have a shared computer, you may want to set up other users with a Standard Account, as they won’t be able to make changes to the Registry anyway.

• where on disk is space allocated for new files inside LVM lv with ext4 file system?

  - by Jost

  I run a multi-disk server with LVM2. Several large disks serve as LVM2 physical volumes for one volume group, containing one logical volume formatted with ext4. Nothing fancy, just your standard linear setup. Recently an additional, very small disk was added as physical volume to that volume group and I expanded both the logical volume, and the ext4 file system therein onto that disk. This lv is used to store incremental backups using rsync and is only about 30% full, there have rarely been any files deleted from it, only incremental writes. Now this new HDD I added to the pre-existing volume group has unexpectedly died on me, and the volume group won't come up because it is missing one physical volume. As fate will have it, this WAS the "in an event of catastrophic failure on the primary server"-backup, the event happened, the boss is not happy, so this kinda has to work... According to this (Part 3): http://www.novell.com/coolsolutions/appnote/19386.html it is possible to trick LVM into starting anyway by creating a new pv with identical metadata to the failed disk, which will make the volume accessible, but of course leave giant holes in the file system. I have'n tried it yet, because it involves repairing (writing to) the file system which eliminates the possibility of trying other things if it fails. Now my question is: How does this setup actually allocate disk space for new data? Is it allocated linearly from beginning to end of PVs, in the order they were added to the vg? Is it striped somehow in order to increase performance/balance load? since this defective disk was added only later to an existing lvm2 vg and lv, containing a half-empty ext4, what are the chances that there was never any data written to the defective disk? In other words: what are the chances of recovering all my data, even without the defective disk, by just starting the volume group as-is? Am I about to go spend $1500 on having 250GB of empty space recovered when I send the defective disk in for repair? Is there a way to check without mounting the file system and opening the files, hoping they contain something other than zeros? (comparing addresses of used data blocks inside ext4 to address ranges that were on the missing pv, something like that, preferably easy to automate) I know bitwise-copying the entire lv into an image file before trying to repair the ext4 would probably be a good idea, but since this lv is very large and I just suffered major file system failure on several systems it is probably a luxury I don't have... Any suggestions?

• Count a row VS Save the Row count after each update

  - by SAFAD

  I want to know whether saving row count in a table is better than counting it each time of the proccess. Quick Example : A visitor goes to Group Clan, the page displays clan information and Members who have joined the group,Should the page look for all the users who joined the clan and count them, or just display the number of members already saved in table ? I think the first one is not possible to get manipulated with but IT MIGHT cost performance Your Ideas ?

• Service Broker, not ETL

  - by jamiet

  I have been very quiet on this blog of late and one reason for that is I have been very busy on a client project that I would like to talk about a little here. The client that I have been working for has a website that runs on a distributed architecture utilising a messaging infrastructure for communication between different endpoints. My brief was to build a system that could consume these messages and produce analytical information in near-real-time. More specifically I basically had to deliver a data warehouse however it was the real-time aspect of the project that really intrigued me. This real-time requirement meant that using an Extract transformation, Load (ETL) tool was out of the question and so I had no choice but to write T-SQL code (i.e. stored-procedures) to process the incoming messages and load the data into the data warehouse. This concerned me though – I had no way to control the rate at which data would arrive into the system yet we were going to have end-users querying the system at the same time that those messages were arriving; the potential for contention in such a scenario was pretty high and and was something I wanted to minimise as much as possible. Moreover I did not want the processing of data inside the data warehouse to have any impact on the customer-facing website. As you have probably guessed from the title of this blog post this is where Service Broker stepped in! For those that have not heard of it Service Broker is a queuing technology that has been built into SQL Server since SQL Server 2005. It provides a number of features however the one that was of interest to me was the fact that it facilitates asynchronous data processing which, in layman’s terms, means the ability to process some data without requiring the system that supplied the data having to wait for the response. That was a crucial feature because on this project the customer-facing website (in effect an OLTP system) would be calling one of our stored procedures with each message – we did not want to cause the OLTP system to wait on us every time we processed one of those messages. This asynchronous nature also helps to alleviate the contention problem because the asynchronous processing activity is handled just like any other task in the database engine and hence can wait on another task (such as an end-user query). Service Broker it was then! The stored procedure called by the OLTP system would simply put the message onto a queue and we would use a feature called activation to pick each message off the queue in turn and process it into the warehouse. At the time of writing the system is not yet up to full capacity but so far everything seems to be working OK (touch wood) and crucially our users are seeing data in near-real-time. By near-real-time I am talking about latencies of a few minutes at most and to someone like me who is used to building systems that have overnight latencies that is a huge step forward! So then, am I advocating that you all go out and dump your ETL tools? Of course not, no! What this project has taught me though is that in certain scenarios there may be better ways to implement a data warehouse system then the traditional “load data in overnight” approach that we are all used to. Moreover I have really enjoyed getting to grips with a new technology and even if you don’t want to use Service Broker you might want to consider asynchronous messaging architectures for your BI/data warehousing solutions in the future. This has been a very high level overview of my use of Service Broker and I have deliberately left out much of the minutiae of what has been a very challenging implementation. Nonetheless I hope I have caused you to reflect upon your own approaches to BI and question whether other approaches may be more tenable. All comments and questions gratefully received! Lastly, if you have never used Service Broker before and want to kick the tyres I have provided below a very simple “Service Broker Hello World” script that will create all of the objects required to facilitate Service Broker communications and then send the message “Hello World” from one place to anther! This doesn’t represent a “proper” implementation per se because it doesn’t close down down conversation objects (which you should always do in a real-world scenario) but its enough to demonstrate the capabilities! @Jamiet ----------------------------------------------------------------------------------------------- /*This is a basic Service Broker Hello World app. Have fun! -Jamie */ USE MASTER GO CREATE DATABASE SBTest GO --Turn Service Broker on! ALTER DATABASE SBTest SET ENABLE_BROKER GO USE SBTest GO -- 1) we need to create a message type. Note that our message type is -- very simple and allowed any type of content CREATE MESSAGE TYPE HelloMessage VALIDATION = NONE GO -- 2) Once the message type has been created, we need to create a contract -- that specifies who can send what types of messages CREATE CONTRACT HelloContract (HelloMessage SENT BY INITIATOR) GO --We can query the metadata of the objects we just created SELECT * FROM   sys.service_message_types WHERE name = 'HelloMessage'; SELECT * FROM   sys.service_contracts WHERE name = 'HelloContract'; SELECT * FROM   sys.service_contract_message_usages WHERE  service_contract_id IN (SELECT service_contract_id FROM sys.service_contracts WHERE name = 'HelloContract') AND        message_type_id IN (SELECT message_type_id FROM sys.service_message_types WHERE name = 'HelloMessage'); -- 3) The communication is between two endpoints.

• Thank you Geeks With Blogs for letting me join your community!

  - by GreeNTUG

  First, a link to the blog I can no longer edit because Office Live blew away my digital identity and so I can no longer log into it (the source of a loooong blog about protecting your digital identity sometime when I have more time and after it has played out to the end) http://greentug.spaces.live.com/ The following are the communities I participate in: Green & Sustainability.  I run a virtual user group on Green and Sustainability as it relates to developers and software architects.  It was located at greentug.groups.live.com, and we will need to find a new digital location for it, because I am locked out of that site as well. BizSpark Tampa Bay:  I run a BizSpark group for Microsoft technologists (meetup.com, search for BizSpark Tampa Bay) and speak at Code Camps about "No Better Time to Start Your Own Tech Business".  The meetup group facilitates a balanced presentation that is respectful to anyone wanting to start their own business, whether part-time or full-time, whether micro (just you), sustainable (grow to 2-25-ish, self-funded), high growth (get venture capital or other funding, grow it, sell it within 5 years, do it again), or hybrid (the new model going forward).  It is an "action" group, with assignments and homework if you want to get the most out of it.   At the end of a year you will either have your business on the path to where you want it to be, or you will know the steps you need to do to get it there. Women in Technology Have been participating in the Women in Technology community since 2008, my main interests in this area are mentoring women in the workplace to have them believe they can become geeks and double their income, and to mentor them with respect to starting and running their own business. Access 2010/SharePoint 2010.  This is a game-changer with respect to the Access community (the ap both devs and IT Pros love to hate, the other a-word that's not a fruit).  I conducted Lunch n Learns and Brunch n Learns around this topic before the Office 2010/SharePoint 2010 launch, and spoke on the topic at SharePoint Saturday Tampa in Nov 2009. Interested in learning more about: Using Silverlight HD Streaming out in the non-technical world (horses and equestrian sport).  Migrating to Access Web Services and VB .Net from VBA (see the Access 2010/SharePoint 2010 interest above) Windows Phone 7!  Exciting opportunities both for Green and Sustainability and for my "day job" of Environmental, Health & Safety (EHS). My day job is Environmental, Health & Safetey (EHS) consulting and software solutions, where that interfaces with the developer world is with respect to opportunities around Green and Sustainability, The SmartGrid and Juval Lowy's EnergyNet, both of which will require a lot of technology and software to make them work, The new Microsoft Partner competency for "Digital Home", and The Y2K kind of deadline around how managing chemicals in ERP systems is changing because of Global Harmonization, which hits the EU with a hard deadline on 11/30/10 (yes, this year), and hits the USA about 15 months later. Hope you enjoy my contributions to the digital geek community, and feel free to email me, [email protected] (the email leftover after my digital identity was blown away), and [email protected] (this one could go away at some future point) Best, Kathy Malone

• Hello From South Florida

  - by Sam Abraham

  Fellow Blog Readers: I figured I use my first blog post on GeeksWithBlogs to introduce myself.   I recently relocated from Long Island, NY to South Florida where I joined a local company as Software Engineer specializing in technologies such as C#, ASP.Net 3.5, WCF, Silverlight, SQL Server 2008 and LINQ, to name a few. I am an MCP and MCTS ASP.Net 3.5, looking to get my .Net 4.0 certification soon.   Having been in industry for a few years so far, I figured I would share with you my take on the importance of being involved(at least attending) in local user groups.   I am a firm believer that besides using a certain technology, the best way to expand one’s knowledge is by sharing it with others and being equally open to learn from others just as much as you are willing to share what you know.   In my opinion, an important factor that makes a good developer stand-out is his/her ability to keep abreast with the latest and greatest even in areas outside his/her direct expertise.   Additionally, having spoken to various recruiters, technical user group attendees are always favorably looked upon as genuinely interested in their field and willing to take the initiative to expand their knowledge which offers job candidates good leverage when competing for jobs.   I believe I am very blessed to be in an area with a very strong and vibrant developer community. I found in the local .Net community leadership a genuine interest in constantly extending the opportunity to all developers to get more involved and encouraging those who are willing to take that initiative achieve their goal: Speak in meetings, volunteer at events or write and publish articles/blogs about latest and greatest technologies.   With Vishal Shukla (Site director for the West Palm Beach .Net User Group) traveling overseas, I have been extended the opportunity to come on board as site coordinator for FladotNet's WPB .Net User Group along with Venkata Subramanian, an opportunity which I gratefully accepted.   Being involved in running a .Net User Group will surely help me personally and professionally, but my real hope is to use this opportunity to assist in delivering the ultimate common-goal: spread the word about new .Net Technologies, help everybody get more involved and simply have fun learning new things.   With my introduction out of the way, in the next few days I will be posting some notes on an upcoming talk I will be giving about MVC2 and VS2010 in mid-April.   Environment.Exit(0); --Sam

• PASS: Election Changes for 2011

  - by Bill Graziano

  Last year after the election, the PASS Board created an Election Review Committee.  This group was charged with reviewing our election procedures and making suggestions to improve the process.  You can read about the formation of the group and review some of the intermediate work on the site – especially in the forums. I was one of the members of the group along with Joe Webb (Chair), Lori Edwards, Brian Kelley, Wendy Pastrick, Andy Warren and Allen White.  This group worked from October to April on our election process.  Along the way we: Interviewed interested parties including former NomCom members, Board candidates and anyone else that came forward. Held a session at the Summit to allow interested parties to discuss the issues Had numerous conference calls and worked through the various topics I can’t thank these people enough for the work they did.  They invested a tremendous number of hours thinking, talking and writing about our elections.  I’m proud to say I was a member of this group and thoroughly enjoyed working with everyone (even if I did finally get tired of all the calls.) The ERC delivered their recommendations to the PASS Board prior to our May Board meeting.  We reviewed those and made a few modifications.  I took their recommendations and rewrote them as procedures while incorporating those changes.  Their original recommendations as well as our final document are posted at the ERC documents page.  Please take a second and read them BEFORE we start the elections.  If you have any questions please post them in the forums on the ERC site. (My final document includes a change log at the end that I decided to leave in.  If you want to know which areas to pay special attention to that’s a good start.) Many of those recommendations were already posted in the forums or in the blogs of individual ERC members.  Hopefully nothing in the ERC document is too surprising. In this post I’m going to walk through some of the key changes and talk about what I remember from both ERC and Board discussions.  I’ll pay a little extra attention to things the Board changed from the ERC.  I’d also encourage any of the Board or ERC members to blog their thoughts on this. The Nominating Committee will continue to exist.  Personally, I was curious to see what the non-Board ERC members would think about the NomCom.  There was broad agreement that a group to vet candidates had value to the organization. The NomCom will be composed of five members.  Two will be Board members and three will be from the membership at large.  The only requirement for the three community members is that you’ve volunteered in some way (and volunteering is defined very broadly).  We expect potential at-large NomCom members to participate in a forum on the PASS site to answer questions from the other PASS members. We’re going to hold an election to determine the three community members.  It will be closer to voting for Summit sessions than voting for Board members.  That means there won’t be multiple dedicated emails.  If you’re at all paying attention it will be easy to participate.  Personally I wanted it easy for those that cared to participate but not overwhelm those that didn’t care.  I think this strikes a good balance. There’s also a clause that in order to be considered a winner in this NomCom election, you must receive 10 votes.  This is something I suggested.  I have no idea how popular the NomCom election is going to be.  I just wanted a fallback that if no one participated and some random person got in with one or two votes.  Any open slots will be filled by the NomCom chair (usually the PASS Immediate Past President).  My assumption is that they would probably take the next highest vote getters unless they were throwing flames in the forums or clearly unqualified.  As a final check, the Board still approves the final NomCom. The NomCom is going to rank candidates instead of rating them.  This has interesting implications.  This was championed by another ERC member and I’m hoping they write something about it.  This will really force the NomCom to make decisions between candidates.  You can’t just rate everyone a 3 and be done with it.  It may also make candidates appear further apart than they actually are.  I’m looking forward talking with the NomCom after this election and getting their feedback on this. The PASS Board added an option to remove a candidate with a unanimous vote of the NomCom.  This was primarily put in place to handle people that lied on their application or had a criminal background or some other unusual situation and we figured it out. We list an explicit goal of three candidate per open slot. We also wanted an easy way to find the NomCom candidate rankings from the ballot.  Hopefully this will satisfy those that want a broad candidate pool and those that want the NomCom to identify the most qualified candidates. The primary spokesperson for the NomCom is the committee chair.  After the issues around the election last year we didn’t have a good communication plan in place.  We should have and that was a failure on the part of the Board.  If there is criticism of the election this year I hope that falls squarely on the Board.  The community members of the NomCom shouldn’t be fielding complaints over the election process.  That said, the NomCom is ranking candidates and we are forcing them to rank some lower than others.  I’m sure you’ll each find someone that you think should have been ranked differently.  I also want to highlight one other change to the process that we started last year and isn’t included in these documents.  I think the candidate forums on the PASS site were tremendously helpful last year in helping people to find out more about candidates.  That gives our members a way to ask hard questions of the candidates and publicly see their answers. This year we have two important groups to fill.  The first is the NomCom.  We need three people from our membership to step up and fill this role.  It won’t be easy.  You will have to make subjective rankings of your fellow community members.  Your actions will be important in deciding who the future leaders of PASS will be.  There’s a 50/50 chance that one of the people you interview will be the President of PASS someday.  This is not a responsibility to be taken lightly. The second is the slate of candidates.  If you’ve ever thought about running for the Board this is the year.  We’ve never had nine candidates on the ballot before.  Your chance of making it through the NomCom are higher than in any previous year.  Unfortunately the more of you that run, the more of you that will lose in the election.  And hopefully that competition will mean more community involvement and better Board members for PASS. Is this the end of changes to the election process?  It isn’t.  Every year that I’ve been on the Board the election process has changed.  Some years there have been small changes and some years there have been large changes.  After this election we’ll look at how the process worked and decide what steps to take – just like we do every year.
