• How to create Raid 10 with megacli

  - by Henno

  I have OpenFiler storage server. Without installing Windows and MSM, I want to create raid10 array from disks 2 to 21. I have already successfully installed MegaCli to OpenFiler but I'm stuck in figuring out the correct command line for creating a raid 10 array. The documentations says that the syntax for creating a raid 10 is: MegaCli -CfgSpanAdd -r10 -Array0[E:S,E:S] -Array1[E:S,E:S] -aN My enclosure ID is 25, so: [root@linux-h5ut ~]# MegaCli -CfgSpanAdd -r10 -Array0[E25:S02,E25:S21] -Array1[E25:S02,E25:S21] WB Cached NoCachedBadBBU -a0 Invalid input at or near token E I have googled high and low but there doesn't seem to be any example doing raid10 with megaraid (only the syntax). Can anyone explain what is wrong?

• Rough estimate for speed advantage of SAN-via-fibre to san-via-iSCSI when using VMware vSphere

  - by Dirk Paessler

  We are in the process of setting up two virtualization servers (DELL R710, Dual Quadcore Xeon CPUs at 2.3 Ghz, 48 GB RAM) for VMware VSphere with storage on a SAN (DELL Powervault MD3000i, 10x 500 GB SAS drives, RAID 5) which will be attached via iSCSI on a Gbit Ethernet Switch (DELL Powerconnect 5424, they call it "iSCSI-optimized"). Can anyone give an estimate how much faster a fiber channel based solution would be (or better "feel")? I don't mean the nominal speed advantage, I mean how much faster will virtual machines effectively work? Are we talking twice the speed, five times, 10 times faster? Does it justify the price? PS: We are not talking about heavily used database servers or exchange servers. Most of the virtualized servers run below 3-5% average CPU load.

• Python Django Global Variables

  - by Joe J

  Hi all, I'm looking for simple but recommended way in Django to store a variable in memory only. When Apache restarts or the Django development server restarts, the variable is reset back to 0. More specifically, I want to count how many times a particular action takes place on each model instance (database record), but for performance reasons, I don't want to store these counts in the database. I don't care if the counts disappear after a server restart. But as long as the server is up, I want these counts to be consistent between the Django shell and the web interface, and I want to be able to return how many times the action has taken place on each model instance. I don't want the variables to be associated with a user or session because I might want to return these counts without being logged in (and I want the counts to be consistent no matter what user is logged in). Am I describing a global variable? If so, how do I use one in Django? I've noticed the files like the urls.py, settings.py and models.py seems to be parsed only once per server startup (by contrast to the views.py which seems to be parsed eache time a request is made). Does this mean I should declare my variables in one of those files? Or should I store it in a model attribute somehow (as long as it sticks around for as long as the server is running)? This is probably an easy question, but I'm just not sure how it's done in Django. Any comments or advice is much appreciated. Thanks, Joe

• DataTable vs. Collection in .Net

  - by B Pete

  I am writing a program that needs to read a set of records that describe the register map of a device I need to communicate with. Each record will have a handfull of fields that describe the properties of each register. I don't really need to edit or modify the data in my VB or C# program, though I would like to be able to display the data on a grid. I would like to store the data in a CSV file, or perhaps an XML file. I need to enable users to edit the data off-line, preferably in excel. I am considering using a DataTable or a Collection of "Register" objects (which I would define). I prototyped a DataTable, and found I can read/write XML easily using the built in methods and I can easily bind to a DataGridView. I was not able to find a way to retreive info on a single register without using a query that returns a collection of rows, even though I defined a unique primaty key column. The syntax to get a value from a column is also complex, though I could be missing something on both counts. I'm tempted to use a collection of "Register" objects that I can access via a unique key. It would be a little more coding up front, but seems like a cleaner solution overall. I should still be able to use LINQ to dataset to query subsets of registers when I need them, but would also be able to grab a single field using a the key value, something like this: Registers(keyValue).fieldName). Which would be a cleaner approach to the problem? Is there a way to read/write XML into a Collection without needing custom code? Could this be accomplished using String for a key?

• Recycle Bin for Windows Server 2003 File Shares

  - by Joseph Sturtevant

  One of the networks I administrate uses Windows Server 2003 File Shares to provide network storage for users. To prevent against accidental deletion, I use Shadow Copies to create snapshots twice a day. This method is only effective, however, for files which were on the share during the last snapshot. When users accidentally deleted files recently placed on the share, I have no recourse except to remote desktop into the server and attempt retrieval with an undelete utility (this is only effective if the file has not been overwritten). Is there a feature like the Windows Recycle Bin for Windows Server 2003 File Shares? What is the best way to protect my users against accidental file deletion in this scenario?

• proper way to dynamically assign backbone.js view el

  - by kikuchiyo

  I would like to create two ( or more ) view instances, each with different el attributes, and have events bound to them via backbone.js view's events hash ( not through jQuery ). Getting events to trigger when all instantiations have the same el is easy: someView = Backbone.View.extend({ el: '#someDiv', events: { 'click': 'someFunction' }, someFunction: function(){ //Do something here } }); So far, if I assign el in the initialize function, and set events normally as follows, events do not trigger: someView = Backbone.View.extend({ events: { 'click': 'someFunction' }, initialize: function( options ){ this.el = options.el }, someFunction: function(){ //Do something here } }); My first instinct was to have el be a function that returns the string representation of the dom element of interest: someView = Backbone.View.extend({ el: function(){ return '#someDiv-' + this.someNumber }, events: { 'click': 'someFunction' }, initialize: function( options ){ this.someNumber = options.someNumber }, someFunction: function(){ //Do something here } }); However, this triggers someFunction x times if I have x instantiations of someView. Next I tried setting both the el and events attributes in initialize: someView = Backbone.View.extend({ initialize: function( options ){ this.el = options.el this.events = { 'click': 'someFunction' } }, someFunction: function(){ //Do something here } }); but this does not trigger events. At this point I'm pretty much fishing. Does anyone know how instantiate a backbone.js view with an el specific to that instance that has events that only trigger for that instance, and not other instances of the View?

• Script throwing unexpected operator when using mysqldump

  - by Astron

  A portion of a script I use to backup MySQL databases has stopped working correctly after upgrading a Debian box to 6.0 Squeeze. I have tested the backup code via CLI and it works fine. I believe it is in the selection of the databases before the backup occurs, possibly something to do with the $skipdb variable. If there is a better way to perform the function then I'm will to try something new. Any insight would be greatly appreciated. $ sudo ./script.sh [: 138: information_schema: unexpected operator [: 138: -1: unexpected operator [: 138: mysql: unexpected operator [: 138: -1: unexpected operator Using bash -x script here is one of the iterations: + for db in '$DBS' + skipdb=-1 + '[' test '!=' '' ']' + for i in '$IGGY' + '[' mysql == test ']' + : + '[' -1 == -1 ']' ++ /bin/date +%F + FILE=/backups/hostname.2011-03-20.mysql.mysql.tar.gz + '[' no = yes ']' + /usr/bin/mysqldump --single-transaction -u root -h localhost '-ppassword' mysql + /bin/tar -czvf /backups/hostname.2011-03-20.mysql.mysql.tar.gz mysql.sql mysql.sql + rm -f mysql.sql Here is the code. if [ $MYSQL_UP = "yes" ]; then echo "MySQL DUMP" >> /tmp/update.log echo "--------------------------------" >> /tmp/update.log DBS="$($MYSQL -u $MyUSER -h $MyHOST -p"$MyPASS" -Bse 'show databases')" for db in $DBS do skipdb=-1 if [ "$IGGY" != "" ] ; then for i in $IGGY do [ "$db" == "$i" ] && skipdb=1 || : done fi if [ "$skipdb" == "-1" ] ; then FILE="$DEST$HOST.`$DATE +"%F"`.$db.mysql.tar.gz" if [ $ENCRYPT = "yes" ]; then $MYSQLDUMP -u $MyUSER -h $MyHOST -p"$MyPASS" $db > $db.sql && $TAR -czvf - $db.sql | $OPENSSL enc -aes-256-cbc -salt -out $FILE.enc -k $ENC_PASS && rm -f $db.sql else $MYSQLDUMP --single-transaction -u $MyUSER -h $MyHOST -p"$MyPASS" $db > $db.sql && $TAR -czvf $FILE $db.sql && rm -f $db.sql fi fi done fi

• How can I load a view based on how long I hold a UIButton?

  - by Thomas

  Hello all, I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the button press? The tutorial switched the number of taps. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: // Single touch { // Get the first touch. UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; switch ([touch tapCount]) { case 1: // Single Tap. { // Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(showAlertView:) userInfo:nil repeats:NO]; [timer retain]; } break; case 2: // Double tap. break; } } break; case 2: // Double touch { } break; default: break; } } Any suggestions? Thanks! Thomas

• Allow image upload - most efficient way?

  - by K-P

  Hey everyone, In my site, I currently only allow users to import images from other sites rather than uploading it themselves. The main reason for this is because I don't have much storage space on my host (relatively speaking). The host charges quite a bit for additional space. What are the alternatives to hosting images users upload (max 1mb size). Would it be a good idea to purchase separate cheap hosting with "unlimited space" (I know that's not true, but I'm guessing it's more than 1gb)? Or are there some caveats with this approach (e.g. security since the site should not be browsable, but accessed via another server)? Are there alternative ideas that I could employ? Thanks for any suggestions

• Python byte per byte XOR decryption

  - by neurino

  I have an XOR encypted file by a VB.net program using this function to scramble: Public Class Crypter ... 'This Will convert String to bytes, then call the other function. Public Function Crypt(ByVal Data As String) As String Return Encoding.Default.GetString(Crypt(Encoding.Default.GetBytes(Data))) End Function 'This calls XorCrypt giving Key converted to bytes Public Function Crypt(ByVal Data() As Byte) As Byte() Return XorCrypt(Data, Encoding.Default.GetBytes(Me.Key)) End Function 'Xor Encryption. Private Function XorCrypt(ByVal Data() As Byte, ByVal Key() As Byte) As Byte() Dim i As Integer If Key.Length <> 0 Then For i = 0 To Data.Length - 1 Data(i) = Data(i) Xor Key(i Mod Key.Length) Next End If Return Data End Function End Class and saved this way: Dim Crypter As New Cryptic(Key) 'open destination file Dim objWriter As New StreamWriter(fileName) 'write crypted content objWriter.Write(Crypter.Crypt(data)) Now I have to reopen the file with Python but I have troubles getting single bytes, this is the XOR function in python: def crypto(self, data): 'crypto(self, data) -> str' return ''.join(chr((ord(x) ^ ord(y)) % 256) \ for (x, y) in izip(data.decode('utf-8'), cycle(self.key)) I had to add the % 256 since sometimes x is 256 i.e. not a single byte. This thing of two bytes being passed does not break the decryption because the key keeps "paired" with the following data. The problem is some decrypted character in the conversion is wrong. These chars are all accented letters like à, è, ì but just a few of the overall accented letters. The others are all correctly restored. I guess it could be due to the 256 mod but without it I of course get a chr exception... Thanks for your support

• How to fluent-map this (using fluent nhibernate)?

  - by vikasde

  I have two tables in my database "Styles" and "BannedStyles". They have a reference via the ItemNo. Now styles can be banned per store. So if style x is banned at store Y then its very possible that its not banned at store Z or vice verse. What is the best way now to map this to a single entity? Should I be mapping this to a single entity? My Style entity looks like this: public class Style { public virtual int ItemNo { get; set;} public virtual string SKU { get; set; } public virtual string StyleName { get; set; } public virtual string Description { get; set; } public virtual Store Store { get; set; } public virtual bool IsEntireStyleBanned { get; set; } }

• Need some help/advice on WCF Per-Call Service and NServiceBus interop.

  - by Alexey

  I have WCF Per-Call service wich provides data for clients and at the same time is integrated with NServiceBus. All statefull objects are stored in UnityContainer wich is integrated into custom service host. NServiceBus is configured in service host and uses same container as service instances. Every client has its own instance context(described by Juval Lowy in his book in chapter about Durable Services). If i need to send request over bus I just use some kind of dispatcher and wait response using Thread.Sleep().Since services are per-call this is ok afaik. But I am confused a bit about messages from bus, that service must handle and provide them to clients. For some data like stock quotes I just update some kind of statefull object and and then, when clients invoke GetQuotesData() just provide data from this object. But there are numerous service messages like new quote added and etc. At this moment I have an idea to implement something like "Postman daemon" =)) and store this type of messages in instance context. Then client will invoke "GetMail()",recieve those messages and parse them. Problem is that NServiceBus messages are "Interface based" and I cant pass them over WCF, so I need to convert them to types derieved from some abstract class. Dunno what is best way to handle this situation. Will be very gratefull for any advice on this. Thanks in advance.

• how to manage a "resource" array efficiently

  - by Haiyuan Zhang

  The senario of my question is that one need to use a fixed size of array to keep track of certain number of "objects" . The object here can be as simply as a integer or as complex as very fancy data structure. And "keep track" here means to allocate one object when other part of the app need one instance of object and recyle it for future allocation when one instance of the object is returned .Finally ,let me use c++ to put my problme in a more descriptive way . #define MAX 65535 /* 65535 just indicate that many items should be handled . performance demanding! */ typedef struct { int item ; }Item_t; Item_t items[MAX] ; class itemManager { private : /* up to you.... */ public : int get() ; /* get one index to a free Item_t in items */ bool put(int index) ; /* recyle one Item_t indicate by one index in items */ } how will you implement the two public functions of itemManager ? it's up to you to add any private member .

• How to route tree-structured URLs with ASP.NET Routing?

  - by Venemo

  Hello Everyone, I would like to achieve something very similar to this question, with some enhancements. There is an ASP.NET MVC web application. I have a tree of entities. For example, a Page class which has a property called Children, which is of type IList<Page>. (An instance of the Page class corresponds to a row in a database.) I would like to assign a unique URL to every Page in the database. I handle Page objects with a Controller called PageController. Example URLs: http://mysite.com/Page1/ http://mysite.com/Page1/SubPage/ http://mysite.com/Page/ChildPage/GrandChildPage/ You get the picture. So, I'd like every single Page object to have its own URL that is equal to its parent's URL plus its own name. In addition to that, I also would like the ability to map a single Page to the / (root) URL. I would like to apply these rules: If a URL can be handled with any other route, or a file exists in the filesystem in the specified URL, let the default URL mapping happen If a URL can be handled by the virtual path provider, let that handle it If there is no other, map the other URLs to the PageController class I also found this question, and also this one and this one, but they weren't of much help, since they don't provide an explanation about my first two points. I see the following possible soutions: Map a route for each page invidually. This requires me to go over the entire tree when the application starts, and adding an exact match route to the end of the route table. I could add a route with {*path} and write a custom IRouteHandler that handles it, but I can't see how could I deal with the first two rules then, since this handler would get to handle everything. So far, the first solution seems to be the right one, because it is also the simplest. I would really appreciate your thoughts on this. Thank you in advance!

• How to minimize total cost of shortest path tree

  - by Michael

  I have a directed acyclic graph with positive edge-weights. It has a single source and a set of targets (vertices furthest from the source). I find the shortest paths from the source to each target. Some of these paths overlap. What I want is a shortest path tree which minimizes the total sum of weights over all edges. For example, consider two of the targets. Given all edge weights equal, if they share a single shortest path for most of their length, then that is preferable to two mostly non-overlapping shortest paths (fewer edges in the tree equals lower overall cost). Another example: two paths are non-overlapping for a small part of their length, with high cost for the non-overlapping paths, but low cost for the long shared path (low combined cost). On the other hand, two paths are non-overlapping for most of their length, with low costs for the non-overlapping paths, but high cost for the short shared path (also, low combined cost). There are many combinations. I want to find solutions with the lowest overall cost, given all the shortest paths from source to target. Does this ring any bells with anyone? Can anyone point me to relevant algorithms or analogous applications? Cheers!

• What's the best way to read a UDT from a database with Java?

  - by Lukas Eder

  I thought I knew everything about UDTs and JDBC until someone on SO pointed out some details of the Javadoc of java.sql.SQLInput and java.sql.SQLData JavaDoc to me. The essence of that hint was (from SQLInput): An input stream that contains a stream of values representing an instance of an SQL structured type or an SQL distinct type. This interface, used only for custom mapping, is used by the driver behind the scenes, and a programmer never directly invokes SQLInput methods. This is quite the opposite of what I am used to do (which is also used and stable in productive systems, when used with the Oracle JDBC driver): Implement SQLData and provide this implementation in a custom mapping to ResultSet.getObject(int index, Map mapping) The JDBC driver will then call-back on my custom type using the SQLData.readSQL(SQLInput stream, String typeName) method. I implement this method and read each field from the SQLInput stream. In the end, getObject() will return a correctly initialised instance of my SQLData implementation holding all data from the UDT. To me, this seems like the perfect way to implement such a custom mapping. Good reasons for going this way: I can use the standard API, instead of using vendor-specific classes such as oracle.sql.STRUCT, etc. I can generate source code from my UDTs, with appropriate getters/setters and other properties My questions: What do you think about my approach, implementing SQLData? Is it viable, even if the Javadoc states otherwise? What other ways of reading UDT's in Java do you know of? E.g. what does Spring do? what does Hibernate do? What does JPA do? What do you do? Addendum: UDT support and integration with stored procedures is one of the major features of jOOQ. jOOQ aims at hiding the more complex "JDBC facts" from client code, without hiding the underlying database architecture. If you have similar questions like the above, jOOQ might provide an answer to you.

• Execute code on assembly load

  - by Dmitriy Matveev

  I'm working on wrapper for some huge unmanaged library. Almost every of it's functions can call some error handler deeply inside. The default error handler writes error to console and calls abort() function. This behavior is undesirable for managed library, so I want to replace the default error handler with my own which will just throw some exception and let program continue normal execution after handling of this exception. The error handler must be changed before any of the wrapped functions will be called. The wrapper library is written in managed c++ with static linkage to wrapped library, so nothing like "a type with hundreds of dll imports" is present. I also can't find a single type which is used by everything inside wrapper library. So I can't solve that problem by defining static constructor in one single type which will execute code I need. I currently see two ways of solving that problem: Define some static method like Library.Initialize() which must be called one time by client before his code will use any part of the wrapper library. Find the most minimal subset of types which is used by every top-level function (I think the size of this subset will be something like 25-50 types) and add static constructors calling Library.Initialize (which will be internal in that scenario) to every of these types. I've read this and this questions, but they didn't helped me. Is there any proper ways of solving that problem? Maybe some nice hacks available?

• Back up of Streaming server

  - by Maxwell

  I want to take a new streaming server for my website which generally holds videos and audio files. But how do we maintain backup of the streaming server if storage size is increasing day by day. Generally on Database servers, like Sql Server, backups can be easily taken and restored very easily as they do not occupy much space for medium range applications. On the other hand how can we take backup of streaming server? If the server fails, the there should be an alternative server / solution that should decrease downtime of the server. How is the back-end architecture of YouTube built to handle this?

• GWT serialization issue

  - by Eddy

  I am having a heck of a time returning an ArrayList of objects that implement IsSerializable via RPC. The IsSerializable pojo contains one variable, a String, and has a 0 parameter constructor. I have removed the .gwt.rpc file from my war and still I get: com.google.gwt.user.client.rpc.SerializationException: Type 'com.test.myApp.client.model.Test' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = com.test.myApp.client.model.Test@17a9692 at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java:610) I am using GWT 2.0.2 with jdk 1.6.0_18. Any ideas on what might be going on or what I am doing wrong? Here is the code for the Test class and the remote method is returning ArrayList. I even modified the code for it to just return one instance of Test with the same result: the exception above. package com.test.myApp.client.model; import com.google.gwt.user.client.rpc.IsSerializable; public class Test implements IsSerializable{ private String s; public Test() {} public Test(String s) { this.s = s; } public String getS() { return s; } public void setS(String s) { this.s = s; } } Greatly appreciate the help!

• What's the best way to mitigate NFS and sudo?

  - by user225874

  Quick background: We have 40 workstations running Linux. NFS is used extensively for bulk data storage and home directories. This allows users to roam freely will relatively transparent file systems. This is an educational environment where postdocs and students have successfully pulled off a coup of sorts. All have gained root on their individual workstations by grooming a technophobic PI who thinks IT people are evil. If I so much as suggest chroot or sudo restrictions, I'll find myself working out of a broom closet. With that in mind, what's the best way to mitigate something like this below? $ hostname workstation1 $ whoami john $ sudo su jane $ whoami jane $ cp -R /home/nfs/jane /mnt/thumbdrive/

• what might cause a print error in perl?

  - by Mark J Seger

  I have a long running script that every hour opens a file, prints to it and closes the file. I've recently found very rarely, the print is failing, not because I'm testing the status of the print itself but rather due to the fact of missing entries in the file until the system is actually rebooted! I do trap for file open failures and write a message to syslog when that happens and I'm not seeing any open failures so I'm now guessing it may be the print that is failing. I'm not trapping the print failures, which I suspect most people don't but am now going to update that one print. Meanwhile, my question is does anyone know what types of situations could cause a print statement to fail when there is plenty of disk storage and no contention for a file which has been successfully opened in append mode?

• Advice on designing and building distributed application to track vehicles

  - by dario-g

  I'm working on application for tracking vehicles. There will be about 10k or more vehicles. Each will be sending ~250bytes in each minute. Data contains gps location and everything from CAN Bus (every data that we can read from vehicle computer and dashboard). Data are sent by GSM/GPRS (using UDP protocol). Estimated rows with this data per day is ~2000k. I see there 3 main blocks. 1. Multithreaded Socket Server (MSS) - I have it. MSS stores received data to the queue (using NServiceBus). 2. Rule Processor Server (RPS) - this is core of this system. This block is responsible for parsing received data, storing in the database, processing rules, sending messages to Notifier Server (this will be sending e-mails/sms texts). Rule example. As I said between received bytes there will be information about current speed. When speed will be above 120 then: show alert in web application for specified users, send e-mail, send sms text. (There can be more than one instance of RPS). 3. Web application - allows reporting and defining rules by users, monitoring alerts, etc. I'm looking for advice how to design communication between RPS and Web application. Some questions: - Should Web application and RPS have separated databases or one central database will be enough? I have one domain model in web application. If there will be one central database then can I use the same model (objects) on RPS? So, how to send changed rules to RPS? I try to decouple this blocks as much as possible. I'm planning to create different instance of application for each client (each client will have separated database). One client will be have 10k vehicles, others only 100 vehicles.

• Performing text processing on flatpage content to include handling of custom tag

  - by Dzejkob

  Hi. I'm using flatpages app in my project to manage some html content. That content will include images, so I've made a ContentImage model allowing user to upload images using admin panel. The user should then be able to include those images in content of the flatpages. He can of course do that by manually typing image url into <img> tag, but that's not what I'm looking for. To make including images more convenient, I'm thinking about something like this: User edits an additional, let's say pre_content field of CustomFlatPage model (I'm using custom flatpage model already) instead of defining <img> tags directly, he uses a custom tag, something like [img=...] where ... is name of the ContentImage instance now the hardest part: before CustomFlatPage is saved, pre_content field is checked for all [img=...] occurences and they are processed like this: ContentImage model is searched if there's image instance with given name and if so, [img=...] is replaced with proper <img> tag. flatpage actual content is filled with processed pre_content and then flatpage is saved (pre_content is leaved unchanged, as edited by user) The part that I can't cope with is text processing. Should I use regular expressions? Apparently they can be slow for large strings. And how to organize logic? I assume it's rather algorithmic question, but I'm not familliar with text processing in Python enough, to do it myself. Can somebody give me any clues?

• Does Team Foundation support cross-app workitem groups?

  - by drachenstern

  We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?
