• Exchange 2003 mailbox migrated to 2010 not showing up in Address book

  - by TJ

  I have migrated about 45 mailboxes at this point from our single instance of Exchange 2003 to a High Availability Exchange 2010 environment successfully. However one mailbox moved successfully and the user is able to send and receive e-mail internally and externally with no problems but they do not show up in the Global Address List. The OAB is owned by an Exchange 2010 mailbox server. What am I missing?

• Including email, IMs, configs, etc. in documentation or notes

  - by Jason Antman

  The shop I work in is pretty laid-back. We're on a documentation kick, only because historically we've been very bad with it. We do a lot of our brainstorming in face-to-face meetings, and also do a lot of communication via IM in addition to email. While I'm usually pretty good about documentation and keeping copious lab notes, I just finished a build of a host and spent hours searching through IMs, emails, files on my workstation, etc. to pull out anything I missed in my lab notes, which formed a large amount of the basis for the internal documentation. Does anyone have any thoughts on, aside from manually saving things to a project directory, managing various data sources (especially email and IM) and tracking them on project basis? Ideally, I'd like an easy way to put copies of emails, IM logs, etc. into a project-specific directory on my workstation and then just have a cron job that syncs that up with a shared folder. This isn't really a candidate for anything more advanced, as the bulk of the data will be copies of configs, code, etc. Here are the big restrictions: Email is via a centralized Zimbra install, so nothing can happen server-side. My workstation is Linux. Aside from writing Pidgin and Thunderbird plugins that let me tag chats and emails as belonging to a project, and then copy them to the appropriate place... any thoughts? Suggestions? Thanks, Jason

• Server 2008 Print Server vs Network printer

  - by cpgascho

  I have a SBS 2008 Server/Windows 7 environment. We have approx 25 users & 6 Networked printers. What is the recommended way/what are the advantages disadvantages of having all the printers shared through the Server 2008 Print server vs having workstations connect directly to the workstation printers. Off the top of my head using the server 2008 print server is a single point of failure but Should make it easier to deploy/manage the printers.

• Web server HW requirements [closed]

  - by Kimo

  Hello, I am trying to search for a book that would teach me how to choose web server HW requirements (hard disk space/technology, ram, internet connection) based on web site statistics (requests per second, etc...), how to scale webservers in case my website is getter higher traffic, etc All I get from the internet is software-related articles. Does anyone know how I can dig in for this kind of information? May be I am just searching using the wrong keywords. Thanks

• mysql with DRBD on rackspace

  - by Richard Castle

  I am trying to set up a failover secondary MySQL server that is a mirror of my primary MySQL server using DRBD. The problem is that I am on a rackspace cloud server and I need a second partition on both the primary and secondary servers that I will replicate with DRBD. Rackspace does not allow me to create a second partition. I am left with the default single partition. How can I mirror using DRBD?

• How does Amazon EC2 operating system licensing work?

  - by JP

  Hello, I'm new to the cloud and EC2 and am wondering how licensing of operating systems works. Specifically, i spent some time looking at amazon machine images (ami's) and some contain windows and sql server. My question is how does the licensing work: a) Do I install my own licenses once the boxes are available? b) Are these licenses covered by my Amazon bill c) what are any costs associated with this software? Thank in advance, JP

• Our company has 100,000s+ photos, how to store and browse/find these efficiently?

  - by tobefound

  We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

• Amazon EBS root volume persistence

  - by hipplar

  When I launch a new Windows EC2 instance I am given a 30 gig root EBS volume. I'm trying to make sure I understand the EBS terminology and want to make sure I understand this correctly: Q: What happens to my data when a system terminates? The data stored on a local instance store will persist only as long as that instance is alive. However, data that is stored on an Amazon EBS volume will persist independently of the life of the instance. What exactly does "instance is alive" mean? If I write files to the root volume and reboot the instance will the files remain? Or do I physically have to terminate (delete) the instance for the root volume to go away? Thanks

• Gmail: Received an email intended for another person. [closed]

  - by jonescb

  I'm not really sure how email routing works, but someone ordered something on Amazon and I received the email instead of them. Or maybe we both got it, I don't know. The order doesn't show up in my account, so I'm certain I wasn't charged for it, but I shouldn't be getting other peoples' emails. We'll say that my email is [email protected], and somebody who's email is [email protected] places an order on Amazon. The confirmation email is sent to me at [email protected]. I checked the email header, and it did say To: [email protected] which is not my email address. At first I thought that Google ignores periods in email addresses, but I tested the account setup and it doesn't give any error when you put a period in the address. I didn't create the account; I just used the "check availability" function and the address I chose with a period was fine. Maybe someone with knowledge about how Email works could tell me why this happened. Is this a bug in the way Amazon sends emails? Or is it a bug in how Google receives them? Who should I report this issue to?

• fstab line for auto mount drive that all users can read/write

  - by evilblender

  I have installed a cable that connects from the CPU's SATA motherboard connection to a removable drives' ESATA connection. I would like to be able to swap drives on the ESATA connection and have all users be able to read and write to these drives. I have created the directory /archive/ where I would like the drive(s) to mount. The drives are all formatted Fat 32 - but in the future I may use HFS for formatting. When I used the command (as root): mount /dev/sdc1 /archive the drive was mounted (but read only) What can I use in my /etc/fstab file that will allow drives to be mounted and unmounted by all users on the system? (both reading and writing) Also, will I be able to mount and unmount these drives without shutting down? or will I need to reboot every time I want to change drives? Thank you. Jeff

• Migrate to SSD - NTFS mount point for Program Files

  - by Icode4food

  Here is my thought. I have a new computer that I just built and am considering migrating to a SSD. I have Windows all setup and my Development environment configured so I want to avoid having to re-install a bunch of stuff. My thought is to clone my OS (win7) to the SSD and then mount a HDD partion to C:\Program Files (x86)\ with C being my SSD. This way as far as the programs are concerned they still live on the C drive but in reality they are physically located on the HDD. This seems to me like a good idea but after searching around a bit and not having found anyone else that had the same idea, I'm wondering why not. Maybe I am missing something that is obvious to everyone but me. Why is this a good or a bad idea?

• How stressful can be a paid side project?

  - by systempuntoout

  I have developed several side projects for my pleasure at home after my daily job hours and I have never been under pressure with them because you know, if it does not work I can fix it tomorrow with no rush. I'm tempted to start a paid side project with a contractor and I would like to know, from your experience, if it could be bearable or too stressful. I can decide the total amount of hours work in a week and my daily job has peeks of stressful weeks but also quiet days. How stressful can be a paid side project?

• How can you remove Unity?

  - by Brad

  In previous versions of Netbook Remix I was able to disable the netbook-launcher and just have a blank desktop. I liked the speed of the Netbook version but not the interface, this worked well for me. However, now with 10.10 and Unity I'm having trouble doing a similar thing. I tried removing netbook-launcher from the startup and tried uninstalling unity. The best result I got was a black desktop with a panel and a non configurable blank white background. Is Unity soo integrated into this version that I will have to just go with the default ubuntu installation?? In the past the default version has been slower then the Netbook version without the interface. Thanks.

• Why is a menu item disabled when using SWTBot?

  - by reprogrammer

  I've written up a GUI test using SWTBot to test the Extract Method refactoring. I use editor.selectRange() to select a statement to extract into a method. But, when I run the unit test, the Extract Method refactoring menu item is disabled. Thus, SWTBot fails to invoke the refactoring. When we change org.eclipse.jdt.ui.actions.ExtractMethodAction so that the "Extract Method..." menu item is always enabled, our SWTBot passes. But, SWTBot should let us select the menu item without hacking the org.eclipse.jdt.ui plugin. The whole project containing the above unit test is available at github. I've also reported the problem on the Eclipse forum for SWTBot. But, we haven't received a solution from the forum.

• UITableViewRowAnimationBottom doesn't work for last row

  - by GendoIkari

  I've come across a very similar question here: Inserting row to end of table with UITableViewRowAnimationBottom doesn't animate., though no answers have been given. His code was also a little different than mine. I have an extremely simple example, built from the Navigation application template. NSMutableArray *items; - (void)viewDidLoad { [super viewDidLoad]; items = [[NSMutableArray array] retain]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addItem)] autorelease]; } - (void)addItem{ [items insertObject:@"new" atIndex:0]; [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:0]] withRowAnimation:UITableViewRowAnimationBottom]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return items.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [items objectAtIndex:indexPath.row]; return cell; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [items removeObjectAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom]; } } The problem is, when I either insert or delete the very last row in the table, the animation doesn't work at all; the row just appears or disappears instantly. This only happens with UITableViewRowAnimationBottom, but that's the animation that makes the most sense for creating or deleting table cells in this way. Is this a bug in Apple's framework? Or does it do this on purpose? Would it make sense to add an extra cell to the count, and then setup this cell so that it looks like it's not there at all, just to get around this behavior?

• SVN: Create a dump file of a folder

  - by DarkJaff

  I'm trying to create a dump file of a folder in my SVN repository.(My goal is to import this dump on another repository, but that's another story). I've read like 20 pages about this and they all tell me to use svndumpfilter but I can't seem to make it work. Here is my command: C:\>svnadmin dump d:/SvnData/TestingSVN/ | svndumpfilter include /TestingSVN/Trunk/Fms/ > d:\FMS.txt The output in the command line is this strange thing: Including prefixes: '/TestingSVN/Trunk/Fms' * Dumped revision 0.

Persons that have both hobby A and B, and persons that have hobby A but not B. How can I write these two queries? Can't figure out how to do this with joining and all...

• is this aes encryption wrapper safe ? - yet another take...

  - by user393087

  After taking into accound answers for my questions here and here I created (well may-be) improved version of my wrapper. The key issue was what if an attacker is knowing what is encoded - he might then find the key and encode another messages. So I added XOR before encryption. I also in this version prepend IV to the data as was suggested. sha256 on key is only for making sure the key is as long as needed for the aes alg, but I know that key should not be plain text but calculated with many iterations to prevent dictionary attack function aes192ctr_en($data,$key) { $iv = mcrypt_create_iv(24,MCRYPT_DEV_URANDOM); $xor = mcrypt_create_iv(24,MCRYPT_DEV_URANDOM); $key = hash_hmac('sha256',$key,$iv,true); $data = $xor.((string)$data ^ (string)str_repeat($xor,(strlen($data)/24)+1)); $data = hash('md5',$data,true).$data; return $iv.mcrypt_encrypt('rijndael-192',$key,$data,'ctr',$iv); } function aes192ctr_de($data,$key) { $iv = substr($data,0,24); $data = substr($data,24); $key = hash_hmac('sha256',$key,$iv,true); $data = mcrypt_decrypt('rijndael-192',$key,$data,'ctr',$iv); $md5 = substr($data,0,16); $data = substr($data,16); if (hash('md5',$data,true)!==$md5) return false; $xor = substr($data,0,24); $data = substr($data,24); $data = ((string)$data ^ (string)str_repeat($xor,(strlen($data)/24)+1)); return $data; } $encrypted = aes192ctr_en('secret text','password'); echo $encrypted; echo aes192ctr_de($encrypted,'password'); another question is if ctr mode is ok in this context, would it be better if I use cbc mode ? Again, by safe I mean if an attacter could guess password if he knows exact text that was encrypted and knows above method. I assume random and long password here. Maybe instead of XOR will be safer to random initial data with another run of aes or other simpler alg like TEA or trivium ?

• URL conventions for Maps on Windows Phone 7

  What is the best practice for opening a map from the mobile internet explorer on windows phone 7? On BlackBerry you use a JavaScript method and on Android/iOS you simply link to a google maps URL. I am planning to integrate the different ways of opening maps into my mobile geo javascript library and don't have a windows phone device. http://code.google.com/p/geo-location-javascript/ Thanks, Stan Wiechers

• Boost Property_Tree iterators, how to handle them?

  - by Andry

  Hello... I am sorry but I asked a question about the same argument before, but my problem concerns another aspect of the one described in that question (How to iterate a boost...). My problem is this, take a look at the following code: #include <iostream> #include <string> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> #include <boost/algorithm/string/trim.hpp> int main(int argc, char** argv) { using boost::property_tree::ptree; ptree pt; read_xml("try.xml", pt); ptree::const_iterator end = pt.end(); for (ptree::const_iterator it = pt.begin(); it != end; it++) std::cout << "Here " << it->? << std::endl; } Well, as told me in the previous question, there is the possibility to use iterators on property_tree in Boost, but I do not know what type it is... and what methods or properties I can use... Well, I assume that it must be another ptree or something representing another xml hierarchy to be browsed again (if I want) but documentation about this is very bad... I do not know why, but in boost docs I cannot find nothing good about this... just something about a macro to browse nodes, but this approach is one I would really like to avoid... Well, the question is so... Once getting the iterator on a ptree, how can I access node name, value, parameters (a node in a xml file)? Thankyou

• Conditionals in Antlr String Templates

  - by Pat Long - Munkii Yebee

  We are using Antlr StringTemplates to give control over how a Entity's Name is output. The basic Stringtemplate is $FirstName$ $Initial$ $LastName$, $Suffix$, $Degree$ I want to add some smarts to that template so that the commas are only output when necessary i.e. The first comma is only output when there is a Suffix or Degree and the second commas is only output if there is a suffix. I tried the following template string bit it does not work. I guess I have misunderstood $FirstName$ $Initial$ $LastName$ <if(Suffix|Degree)>,<endif>, $Suffix$ <if(Suffix)>,<endif> $Degree$ If it helps we process the templates using this C# StringTemplate stringtemplate = new Antlr.StringTemplate.StringTemplate(template.Data); foreach (Pair<string, string> pair in dictionary) { if (pair.First != null && pair.Second != null) { stringtemplate.SetAttribute(pair.First, pair.Second); } } return stringtemplate.ToString();
