  • SSRS2008R2 report times out, but the underlying query executes in the Management Studio

    - by Matthew Belk
    A customer of mine recently moved servers and the new server has SQL2008R2. His old server was SQL2005. The new server has substantially better CPU, RAM, and disk performance than the old, but several reports time out while executing. When I run the underlying query in the SQL Management Studio, the query executes in sub-second time. The exact error message returned via the Report Manager UI is: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It must be noted that this database is not just analytical; it's also fairly transactional, although the transaction volume is not exceptionally high. What can I do to improve the performance of the SSRS query engine? Are there settings in the data source I can adjust, or in the SSRS config files?

  • Microsoft SQL Server Management Studio causing system freeze

    - by CRoshanLG
    I'm experiencing very slow response from MSSMS and it causes other applications to slow down. Specially Skype crashes after few seconds from opening MSSMS, showing an error called "Disk I/O Error". I'm regularly using few applications (Sublime text, MS Word, Firefox, Outlook, Skype and one or two other apps) simultaneously. The system works fine when MSSMS is not in use! But as soon as MSSMS is opened, all the apps start to freeze (MSSMS also responds very slow). This problem has been there for about a week now (I haven't installed any apps or haven't made any changes to the system during that time). -- System Specifications -- Processor: Core i3 (3.1 GHz) RAM: 4 GB OS: Windows 7 Professional (64 bit) Free space in C drive: ~ 100 GB MS SQL Server 2008 R2 Microsoft SQL Server Management Studio version - 10.50.1600.1 I've tried to find a reason for this but there are no helpful information in the web! There are some solutions suggested (in forums and in Skype Support pages) for the Skypes' "Disk I/O Error", all of which I tried but does not solve the problem. Has anyone faced the same senario? (and hopefully) knows a solution? Systems Log I don't have much knowledge in interpreting the System Log, but I think the Critical and Warnings are not helpful. But there are lots of Error logs which might be useful. In source Kernal-General there are few similar errors saying "An I/O operation initiated by the Registry failed unrecoverably.The Registry could not flush hive (file): <some file>" In source atapi also there are few similar errors -- "The driver detected a controller error on \Device\Ide\IdePort0." (all errors has occurred in 'IdePort0') In Application Error, there are several errors logged, and following is the latest one. Both the Errors which has occurred today is similar (to this one). As it is from Ssms.exe, I guess this is relevant to the cause of problem. But as I said above I can't understand what it means!

  • Change Windows Authentication user for Sql Server Management Studio

    - by Asmor
    We're using Sql Server 2005 with Windows Authentication setup. So normally, when you log in using e.g. Sql Server Management Studio, it forces you to log in at MACHINE_NAME\Username. Anyways, on this one particular computer, the person said they had to make a new account called User01 to do something and showed me where she'd created it under security in the "master" system database. And so now when she logs in, it's listed as MACHINE_NAME\User01 (not the actual Windows user name). It's still set to Windows Authentication, though, and I'm unable to change the login name. Now here's where the real problem comes in... I didn't realize that she was being logged in under this user name at the time, and I disabled it to see what would happen. Now I can't log into the server under her account. I created a new account in Windows called test, and as expected SSMS had the username as MACHINE_NAME\test, and I was able to log in fine. However, the area where the User01 account was listed is not visible to me as far as I can tell and so I can't reenable it. I also tried running the following query: alter login User01 ENABLE And got this error: Msg 15151, Level 16, State 1, Line 1 Cannot alter the login 'User01', because it does not exist or you do not have permission. So in a nutshell, ideally I'd like to reenable User01 somehow, just to get things back to where they used to be. Failing that, how can I force SSMS to log in using the Windows account name as it should be, rather than trying to use User01?

  • SharePoint, Exchange and Incoming Emails Without Directory Management Services

    - by Nariman
    Trying to keep this as simple as possible. We've already created the email accounts that we need (e.g. account[1-20]@domain.com) on Exchange/AD. We'd like to now enable incoming emails on SharePoint 2007 lists corresponding to these accounts. My thinking is we don’t need to configure Directory Management Services [2] – the architecture will be simpler without it and the application doesn’t require these services. However, we still need to route messages from Exchange to either local SMTP services (via the connector described in the articles below) or by user-specific drop-folder settings (if permitted by Exchange). So the question is: can we instruct Exchange to use a drop folder just for accounts account[1-20]@domain.com? or do we need to change the accounts to account[1-20]@sharepointsmtp.domain.com and re-route those message to the local SMTP service that will drop them on disk? I've read the material below.

  • VirtualBox management interface unreliability

    - by Arlen Cuss
    I'm using VirtualBox 3.2.8_OSE with 20 VMs running, and everything's going fine. I find that if I hammer the VBoxManage interface, all sorts of interesting things happen, usually necessitating either a restart of the VM in question, or of all VMs. For instance, if I use VBoxManage guestcontrol execute to run processes, after a few hours of using it maybe once or twice a minute on any given VM, it'll mysteriously start reporting VERR_NOT_IMPLEMENTED and refusing to do anything—sometimes trying to restart /usr/sbin/VBoxService on the VM itself will get it back in working order, but often it won't, and in the meantime, no data can be collected using VBoxManage. Such data includes the VM's IP, so if I hadn't recorded it earlier, I'm usually in trouble and have no option but to portscan the network for it, or kill the VM's process on the host manually and restart it. This one I haven't narrowed down yet, but it seems that even using VBoxManage guestproperty get (to retrieve a machine's IP) frequently and rapidly is enough to cause all VMs' management interfaces to die. The processes are still running fine, but VBoxManage reports them all as "powered off". In the meantime, another process somewhere in the system seems to have decided that their being powered off means they need to be powered on again, and suddenly I have 2x the number of VBoxHeadless processes running than I used to. Has anyone else seen behaviour like this? Is there any workaround? This is a serious impediment to my work, as I've had to resort to a lot of (hacky) caching of data and rate-limiting how often I call VBoxManage, just in case I accidentally bring 20 VMs to their knees.

  • Patch management on multiple systems

    - by Pierre
    I'm in charge of auditing the security configuration of an important farm of Unix servers. So far, I came up with a way to assess the basic configuration but not the installed updates. The very problem here is that I just can't trust the package management tools on those machine. Indeed some of them did not sync with the repository for a long time (So I can't do a "yum check-updates" on Redhat for example). Some of those servers are not even connected to the internet and use an company repository. Another problem is that I have multiple target systems: AIX, Debian, Centos/Redhat, etc... So the version could be different (AIX) and the tools available will be different. And, last but not least, I can't install anything on the target system. So I need to use a script to retrieve the information and either: process it directly or save the information to be able to process it later on a server (Which may happen to run a different distribution than the one on which the information have been retrieved). The best ideas I could come up with were: either retrieve the list of installed packages on the machine (dpkg -l for example on debian) and process it on a dedicated server (Directly parsing the "Packages" file of debian repositories). Still, the problem remains the same for AIX and Redhat... or use Nessus' scripts to assess vulnerability on the installed packages, but I find this a bit dirty. Does anyone know any better/efficient way of doing this ? P.S: I already took time to review some answers to similar problems. Unfortunately Chef, puppet, ... don't meet the requirements I have to meet. Edit: Long story short. I need to have the list of missing updates on a Unix system just like MBSA on Windows. I'm not authorized to install anything on this system as it's not mine. All I have are scripts languages. Thanks.

  • Drowning in documents - recommend doc management solutions?

    - by Martin Day
    I've been researching document management lately. I want to organise my docs at home and also at the office. Finding affordable solutions one can actually test drive is quite hard. Some that I've downloaded just don't seem to work (testing on brand new Vista PC). I've seen some software on Amazon like Paperport but not really sure what they're like. For home I'd like something to organise files, full text search, good scanner integration, nice interface etc. But for the office it seems harder. I need something that does proper workflow and keeps versions. It will have an audit trail. Documents can be approved, checked in/out etc. I know a few clients who would like something similar. It would be great just to import thousands of documents from a shared drive and get them indexed with dupes killed. I'd like to be super clear about how/where the documents are being stored so that maintenance and backups are clear. My Google/twitter searches lead back to the same tired and vague webpages pushing what look like expensive and custom made solutions. Some might be very good I suppose but it's darn hard to tell. I don't mind a hosted package but all in all I don't think something like Google Docs, as good as it is now, will work. There are too many quirks and missing features (as compared to Office). Being able to work directly with the common Office file formats is important. I've noted a similar sounding question asked here back in August but it didn't seem to turn up too many solutions that I could easily and quickly apply. Also there could have been some changes since then so I feel it's worth asking.

  • CMSs & ERPs for hospital management system

    - by Akshey
    Hi, What are the best free CMSs or CMS plugins or ERPs or any other free tools available for developing a hospital management system? I want to develop it for a children's hospital run by my father. The hospital is small with two doctors. Currently, everything is done manually on paper. The main entities who will be using the system are: Receptionist, the two doctors, chemist and the medical laboratorist. They will use it majorly for keeping the records of the patient. The patients would not be interacting with the system directly. The system needs to be user friendly and should be easy to learn. I was thinking to develop such a system using a CMS or an ERP or any other free tool. I have used wordpress/drupal in past but never used an ERP. Can you please guide me to make such a system using free, and preferably open source, tools? Update: I think it will be mostly a form driven system. What would be easy and better: creating the forms in drupal or using a php framework like symphony or cakePHP? Thanks, Akshey

  • Spring Security session-management setting and IllegalStateException

    - by JayL
    I'm trying to add <session-management> in my Spring Security namespace configuration so that I can provide a different message than the login page when the session times out. As soon as I add it to my configuration it starts throwing "IllegalStateException: Cannot create a session after the response has been committed" when I access the app. I'm using Spring Security 3 and Tomcat 6. Here's my configuration: <http> <intercept-url pattern="/go.htm" access="ROLE_RESPONDENT" /> <intercept-url pattern="/complete.htm" access="ROLE_RESPONDENT" /> <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" /> <form-login login-processing-url="/j_spring_security_check" login-page="/login.htm" authentication-failure-url="/login.htm?error=true" default-target-url="/go.htm" /> <anonymous/> <logout logout-success-url="/logout_message.htm"/> <session-management invalid-session-url="/login.htm" /> </http> Everything works great until I add in the <session-management> line. What am I missing?

  • SQL SERVER – Discard Results After Query Execution – SSMS

    - by pinaldave
    The first thing I do any day is to turn on the computer. Today I woke up and as soon as I turned on the computer I saw a chat message from a friend. He was a bit confused and wanted me to help him. Just as usual I am keeping the relevant conversation in focus and documenting our conversation as chat. Let us call him Ajit. Ajit: Pinal, every time I run a query there is no result displayed in the SSMS but when I run the query in my application it works and returns an appropriate result. Pinal:  Have you tried with different parameters? Ajit: Same thing. However, it works from another computer when I connect to the same server with the same query parameters? Pinal: What? That is new and I believe it is something to do with SSMS and not with the server. Send me screenshot please. Ajit: I believe so, let me send you a screenshot, Pinal: (looking at the screenshot) Oh man, there is no result-tab at all. Ajit: That is what the problem is. It does not have the tab which displays the result. This works just fine from another computer. Pinal: Have you referred Nakul’s blog post – SSMS – Query result options – Discard result after query executes, that talks about setting which can discard the query results after execution. (After a while) Ajit: I think it seems like on the computer where I am running the query my SSMS seems to have the option enabled related to discarding results. I fixed it by following Nakul’s blog post. Pinal: Great! Quite often I get the question what is the importance of the feature. Let us first see how to turn on or turn off this feature in SQL Server Management Studio 2012. In SSMS 2012 go to Tools >> Options >> Query Results > SQL Server >> Results to Grid >> Discard Results After Query Execution. When enabled this option will discard results after the execution. The advantage of disabling the option is that it will improve the performance by using less memory. However the real question is why would someone enable or disable the option. What are the cases when someone wants to run the query but do not care about the result? Matter of the fact, it does not make sense at all to run query and not care about the result. The matter of the fact, I can see quite a few reasons for using this option. I often enable this option when I am doing performance tuning exercise. During performance tuning exercise when I am working with execution plans and do not need results to verify every time or when I am tuning Indexes and its effect on execution plan I do not need the results. In this kind of situations I do keep this option on and discard the results. It always helps me big time as in most of the performance tuning exercise I am dealing with huge amount of the data and dealing with this data can be expensive. Nakul’s has done the experiment here already but I am going to repeat the same again using AdventureWorks Database. Run following T-SQL Script with and without enabling the option to discard the results. USE AdventureWorks2012 GO SELECT * FROM Sales.SalesOrderDetail GO 10 After enabling Discard Results After Query Execution After disabling Discard Results After Query Execution Well, this is indeed a good option when someone is debugging the execution plan or does not want the result to be displayed. Please note that this option does not reduce IO or CPU usage for SQL Server. It just discards the results after execution and a good help for debugging on the development server.

  • Oracle Announces Release of PeopleSoft HCM 9.1 Feature Pack 2

    - by Jay Zuckert
    Big things sometimes come in small packages.  Today Oracle announced the availability of PeopleSoft HCM 9.1 Feature Pack 2 which delivers a new HR self service user experience that fundamentally changes the way managers and employees interact with the HCM system.  Earlier this year we reviewed a number of new concept designs with our Customer Advisory Boards.  With the accelerated feature pack development cycle we have adopted, these innovations are  now available to all 9.1 customers without the need for an upgrade.   There are no new products that need to be licensed for the capabilities below. For more details on Feature Pack 2, please see the Oracle press release. Included in Feature Pack 2 is a new search-based menu-free navigation that allows managers to search for employees by name and take actions directly from the secure search results.  For example, a manager can now simply type in part of an employee’s first or last name and receive meaningful results from documents related to performance, compensation, learning, recruiting, career planning and more.   Delivered actions can be initiated directly from these search results and the actions are securely tied to HCM security and user role.  The feature pack also includes new pages that will enable managers to be more productive by aggregating key employee data into a single page.  The new Manager Dashboard and Talent Summary provide a consolidated view of data related to a manager’s team and individual team members, respectively.   The Manager Dashboard displays information relevant to their direct reports including team learning, objective alignment, alerts, and pending approvals requiring their attention.  The Talent Summary provides managers with an aggregated view of talent management-related data for an individual employee including performance history, salary history, succession options, total rewards, and competencies.   The information displayed in both the Manager Dashboard and Talent Summary is configurable by system administrators and can be personalized by each of your managers. Other Feature Pack 2 enhancements allow organizations to administer Matrix or Dotted-Line Relationship Management, which addresses the challenge of tracking and maintaining project-based organizations that cut across the enterprise and geographic regions.  From within the Company Directory and Org Viewer organization charts, managers now have access to manager self-service transactions from related actions.  More than 70 manager and employee self-service transactions have been tied into the related action framework accessible from Org Viewer, Manager Dashboard, Talent Summary and Secure Enterprise Search (SES) results.  In addition to making it easier to access manager self-service transactions, the feature pack delivers streamlined transaction pages making everyday tasks such as promoting an employee faster and more efficient. With the delivery of PeopleSoft HCM 9.1 Feature Pack 2, Oracle continues to deliver on its commitment to our PeopleSoft customers.  With this feature pack, HCM 9.1 customers will be able to deploy the newest functionality quickly, without a major release upgrade, and realize added value from their existing PeopleSoft investment.    For customers newly deploying 9.1, a new download with all of Feature Pack 2  will be available early next year.   This will aslo include recertified upgrade paths from 8.8, 8.9 and 9.0, for customers in the upgrade process.

  • PowerShell Script To Find Where SharePoint 2007 Features Are Activated

    - by Brian T. Jackett
    Recently I posted a script to find where SharePoint 2010 Features Are Activated.  I built the original version to use SharePoint 2010 PowerShell commandlets as that saved me a number of steps for filtering and gathering features at each level.  If there was ever demand for a 2007 version I could modify the script to handle that by using the object model instead of commandlets.  Just the other week a fellow SharePoint PFE Jason Gallicchio had a customer asking about a version for SharePoint 2007.  With a little bit of work I was able to convert the script to work against SharePoint 2007.   Solution    Below is the converted script that works against a SharePoint 2007 farm.  Note: There appears to be a bug with the 2007 version that does not give accurate results against a SharePoint 2010 farm.  I ran the 2007 version against a 2010 farm and got fewer results than my 2010 version of the script.  Discussing with some fellow PFEs I think the discrepancy may be due to sandboxed features, a new concept in SharePoint 2010.  I have not had enough time to test or confirm.  For the time being only use the 2007 version script against SharePoint 2007 farms and the 2010 version against SharePoint 2010 farms.    Note: This script is not optimized for medium to large farms.  In my testing it took 1-3 minutes to recurse through my demo environment.  This script is provided as-is with no warranty.  Run this in a smaller dev / test environment first. 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 function Get-SPFeatureActivated { # see full script for help info, removed for formatting [CmdletBinding()] param(     [Parameter(position = 1, valueFromPipeline=$true)]     [string]     $Identity )#end param     Begin     {         # load SharePoint assembly to access object model         [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")             # declare empty array to hold results.

  • Oracle Executive Strategy Brief: Enterprise-Grade Cloud Applications

    - by B Shashikumar
    Cloud Computing has clearly evolved into one of the dominant secular trends in the industry. Organizations are looking to the cloud to change how they buy and consume IT. And its no longer about just lower up-front costs. The cloud promises to deliver greater agility and free up resources to focus on innovation versus running and maintaining systems. But are organizations actually realizing these benefits? The full promise of cloud is not being realized by customers who entrust their business to multiple niche cloud providers. While almost 9 out of 10 companies  expect more IT agility with cloud, only 47% are actually getting it (Source: 2011 State of Cloud Survey by Symantec). These niche cloud customers have also seen the promises of lower costs, efficiency gains, improved security, and compliance go unfulfilled. Having one cloud provider for customer relationship management (CRM) and another for human capital management (HCM), and then trying to glue these proprietary systems together while integrating to a back-office financial system can add to complexity and long-term costs. Completing a business process or generating an integrated report is cumbersome, and leverages incomplete data. Why can’t niche cloud providers deliver on the full promise of cloud? It’s simple: you still need to complete business processes. You still need reporting that enables you to take action using data from multiple systems. You still have to comply with SOX and other industry regulations. These requirements don’t go away just because you deploy in the cloud. Delivering lower up-front costs by enabling customers to buy software as a service (SaaS) is the easy part. To get real value that lasts longer than your quarterly report, it’s important to realize the benefits of cloud without compromising on functionality and while having the right level of control and flexibility. This is the true promise of cloud. Oracle’s cloud strategy centers around delivering the benefits of cloud—without compromise. We uniquely empower our customers with complete solutions and choice. From the richest functionality to integrated reporting and great user experience. It’s all available in the cloud. And it works not just with other Oracle cloud applications, but with your existing Oracle and third-party systems as well. This helps protect your current investments and extend their value as you journey to the cloud. We’ve made the necessary investments not only in our applications but also in the underlying technology that makes it all run—from the platform down to the hardware and operating system. We make it all. And we’ve engineered it to work together and be highly optimized for our customers, in the cloud. With Oracle enterprise-grade cloud applications, you get the benefits of cloud plus more power, more choice, and more confidence. Read more about how you can realize the true advantage of Cloud with Oracle Enterprise-grade Cloud applications in the Oracle Executive Strategy Brief here.  You can also attend an Oracle Cloud Conference event at a city near you.

  • A programmer who doesn't get to program - where to turn? [closed]

    - by Just an Anon
    I'm in my mid 20's, and have been working as a full time programmer / developer for the last ~6 years, with several years of part-time freelancing before this, and three straight years of freelancing in the middle of this short career. I work mostly with PHP and the Drupal framework. By and large, I focus on programming custom pieces of functionality; these, of course, vary greatly from project to project. I've got years of solid experience with OOP (have done some Java & C# years ago, too) including intensive experience with front-end development, and even some design work. I've lead small teams (2-4 people) of developers. And of course, given the large amount of freelancing, I've got decent project- & client-management skills. My problem is staying motivated at any place of employment. In the time mentioned I've worked (full-time) at six local companies. The longest I've stayed at any company was just over a year. I find that I'll get hired and be very excited and motivated for the first few months, but the work quickly gets "stale." By that I mean that the interesting components (ie. the programming) get done, and the rest of the work turns into boring cleanup (move a button, add text, change colours, add a field). I don't get challenged, and I don't feel like I'm learning anything new. This happens repeatedly time and time again, and I always end up leaving for either a new opportunity, or to freelance. I'm wondering if perhaps I've painted myself into a corner with the rather niche work market (although with very high demand and good compensation) and need to explore other career choices. Another possibility is that I may be choosing the wrong places of employment, mostly small agencies, and need to look into working for a larger, more established firm. I find programming, writing code, and architecting solutions very rewarding. When I'm working on an interesting problem I lose all sense of time and 14-16 hours can fly by like minutes. I get the same exciting feeling when I'm doing high-level planning of a complex system, breaking up the work and figuring out how everything will tie-in together. I absolutely hate doing small, "stupid" changes that pose no challenge, yet seem to make up more and more of my work. I want to find a workplace where I will get to work on such tasks, be challenged, and improve in all areas of product development. This maybe a programming job, management, architecture of desktop apps, or may be managing a taco stand on a beach in Mexico - I don't know, and I need some advice and real-world feedback. What are some job areas worth exploring? The requirements are fairly simple: working with computers interacting with others challenging decent pay (I'm making just short of 90k / year with a month of vacation & some benefits, and would like to stay in this range, but am willing to take a temporary cut in pay for a more interesting position) Any advice would be much appreciated!

  • SCCM SP2 - OOB Management Certificates Problems

  • How I understood monads, part 1/2: sleepless and self-loathing in Seattle

    - by Bertrand Le Roy
    For some time now, I had been noticing some interest for monads, mostly in the form of unintelligible (to me) blog posts and comments saying “oh, yeah, that’s a monad” about random stuff as if it were absolutely obvious and if I didn’t know what they were talking about, I was probably an uneducated idiot, ignorant about the simplest and most fundamental concepts of functional programming. Fair enough, I am pretty much exactly that. Being the kind of guy who can spend eight years in college just to understand a few interesting concepts about the universe, I had to check it out and try to understand monads so that I too can say “oh, yeah, that’s a monad”. Man, was I hit hard in the face with the limitations of my own abstract thinking abilities. All the articles I could find about the subject seemed to be vaguely understandable at first but very quickly overloaded the very few concept slots I have available in my brain. They also seemed to be consistently using arcane notation that I was entirely unfamiliar with. It finally all clicked together one Friday afternoon during the team’s beer symposium when Louis was patient enough to break it down for me in a language I could understand (C#). I don’t know if being intoxicated helped. Feel free to read this with or without a drink in hand. So here it is in a nutshell: a monad allows you to manipulate stuff in interesting ways. Oh, OK, you might say. Yeah. Exactly. Let’s start with a trivial case: public static class Trivial { public static TResult Execute<T, TResult>( this T argument, Func<T, TResult> operation) { return operation(argument); } } This is not a monad. I removed most concepts here to start with something very simple. There is only one concept here: the idea of executing an operation on an object. This is of course trivial and it would actually be simpler to just apply that operation directly on the object. But please bear with me, this is our first baby step. Here’s how you use that thing: "some string" .Execute(s => s + " processed by trivial proto-monad.") .Execute(s => s + " And it's chainable!"); What we’re doing here is analogous to having an assembly chain in a factory: you can feed it raw material (the string here) and a number of machines that each implement a step in the manufacturing process and you can start building stuff. The Trivial class here represents the empty assembly chain, the conveyor belt if you will, but it doesn’t care what kind of raw material gets in, what gets out or what each machine is doing. It is pure process. A real monad will need a couple of additional concepts. Let’s say the conveyor belt needs the material to be processed to be contained in standardized boxes, just so that it can safely and efficiently be transported from machine to machine or so that tracking information can be attached to it. Each machine knows how to treat raw material or partly processed material, but it doesn’t know how to treat the boxes so the conveyor belt will have to extract the material from the box before feeding it into each machine, and it will have to box it back afterwards. This conveyor belt with boxes is essentially what a monad is. It has one method to box stuff, one to extract stuff from its box and one to feed stuff into a machine. So let’s reformulate the previous example but this time with the boxes, which will do nothing for the moment except containing stuff. public class Identity<T> { public Identity(T value) { Value = value; } public T Value { get; private set;} public static Identity<T> Unit(T value) { return new Identity<T>(value); } public static Identity<U> Bind<U>( Identity<T> argument, Func<T, Identity<U>> operation) { return operation(argument.Value); } } Now this is a true to the definition Monad, including the weird naming of the methods. It is the simplest monad, called the identity monad and of course it does nothing useful. Here’s how you use it: Identity<string>.Bind( Identity<string>.Unit("some string"), s => Identity<string>.Unit( s + " was processed by identity monad.")).Value That of course is seriously ugly. Note that the operation is responsible for re-boxing its result. That is a part of strict monads that I don’t quite get and I’ll take the liberty to lift that strange constraint in the next examples. To make this more readable and easier to use, let’s build a few extension methods: public static class IdentityExtensions { public static Identity<T> ToIdentity<T>(this T value) { return new Identity<T>(value); } public static Identity<U> Bind<T, U>( this Identity<T> argument, Func<T, U> operation) { return operation(argument.Value).ToIdentity(); } } With those, we can rewrite our code as follows: "some string".ToIdentity() .Bind(s => s + " was processed by monad extensions.") .Bind(s => s + " And it's chainable...") .Value; This is considerably simpler but still retains the qualities of a monad. But it is still pointless. Let’s look at a more useful example, the state monad, which is basically a monad where the boxes have a label. It’s useful to perform operations on arbitrary objects that have been enriched with an attached state object. public class Stateful<TValue, TState> { public Stateful(TValue value, TState state) { Value = value; State = state; } public TValue Value { get; private set; } public TState State { get; set; } } public static class StateExtensions { public static Stateful<TValue, TState> ToStateful<TValue, TState>( this TValue value, TState state) { return new Stateful<TValue, TState>(value, state); } public static Stateful<TResult, TState> Execute<TValue, TState, TResult>( this Stateful<TValue, TState> argument, Func<TValue, TResult> operation) { return operation(argument.Value) .ToStateful(argument.State); } } You can get a stateful version of any object by calling the ToStateful extension method, passing the state object in. You can then execute ordinary operations on the values while retaining the state: var statefulInt = 3.ToStateful("This is the state"); var processedStatefulInt = statefulInt .Execute(i => ++i) .Execute(i => i * 10) .Execute(i => i + 2); Console.WriteLine("Value: {0}; state: {1}", processedStatefulInt.Value, processedStatefulInt.State); This monad differs from the identity by enriching the boxes. There is another way to give value to the monad, which is to enrich the processing. An example of that is the writer monad, which can be typically used to log the operations that are being performed by the monad. Of course, the richest monads enrich both the boxes and the processing. That’s all for today. I hope with this you won’t have to go through the same process that I did to understand monads and that you haven’t gone into concept overload like I did. Next time, we’ll examine some examples that you already know but we will shine the monadic light, hopefully illuminating them in a whole new way. Realizing that this pattern is actually in many places but mostly unnoticed is what will enable the truly casual “oh, yes, that’s a monad” comments. Here’s the code for this article: http://weblogs.asp.net/blogs/bleroy/Samples/Monads.zip The Wikipedia article on monads: http://en.wikipedia.org/wiki/Monads_in_functional_programming This article was invaluable for me in understanding how to express the canonical monads in C# (interesting Linq stuff in there): http://blogs.msdn.com/b/wesdyer/archive/2008/01/11/the-marvels-of-monads.aspx

  • Why does 12.04 try but fail to hibernate, even after I enabled hibernation?

    - by Roger Davis
    Regarding the below (-----) info from another post, my system will try (as is said below) to hibernate, but it won't get all the way there. Hard drive activity stops, but it does not shut down. If I turn the power off, then back on, it will start, but I have to "restore previous session" in the browser and other open apps don't restart, with the accompanying hassle. So because it tries, will the suggested fix then cause it to work correctly, or is the literal "try" not really what he means?!? PLEASE NOTE - this is a desktop system, not a laptop. Before enabling hibernation, please try to test whether it works correctly by running pm-hibernate in a terminal. The system will try to hibernate. If you are able to start the system again then you are more or less safe to add an override. To do so, start editing sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla Fill it with this [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes Save by pressing Ctrl-O and exit nano by pressing Ctrl-X Restart and hibernation is back!

  • Two views of Federation: inside out, and outside in

    - by Darin Pendergraft
    IDM customers that I speak to have spent a lot of time thinking about enterprise SSO - asking your employees to log in to multiple systems, each with distinct hard to guess (translation: hard to remember) passwords that fit the corporate security policy for length and complexity is a strategy that is just begging for a lot of help-desk password reset calls. So forward thinking organizations have implemented SSO for as many systems as possible. With the mix of Enterprise Apps moving to the cloud, it makes sense to continue this SSO strategy by Federating with those cloud apps and services.  Organizations maintain control, since employee access to the externally hosted apps is provided via the enterprise account.  If the employee leaves, their access to the cloud app is terminated when their enterprise account is disabled.  The employees don't have to remember another username and password - so life is good. From the outside in - I am excited about the increasing use of Social Sign-on - or BYOI (Bring your own Identity).  The convenience of single-sign on is extended to customers/users/prospects when organizations enable access to business services using a social ID.  The last thing I want when visiting a website or blog is to create another account.  So using my Google or Twitter ID is a very nice quick way to get access without having to go through a registration process that creates another username/password that I have to try to remember. The convenience of not having to maintain multiple passwords is obvious, whether you are an employee or customer - and the security benefit of not having lots of passwords to lose or forget is there as well. Are enterprises allowing employees to use their personal (social) IDs for enterprise apps?  Not yet, but we are moving in the right direction, and we will get there some day.
