  • Comment intégrer des chaines binaires dans un code source python en base64, par Jean-Paul Vidal

    On appellera ici ?chaine binaire? une chaine de caractères dans laquelle chaque caractère peut avoir une valeur de 0 à 255 (bornes comprises). Intégrer une chaine binaire dans le code source n'est pas facile, parce que la chaine binaire peut comporter a priori des octets de 0 à 255, mais les caractères intégrables dans le code source, donc affichables, devraient exclure au minimum les caractères de contrôles inférieurs à 32, certains caractères comme les guillemets ou les backslashs et se limiter à des octets inférieurs 128 (c'est-à-dire rester à 7 bits) pour échapper aux problèmes d'encodages. On va utiliser ici le module base64. Comment intégrer des chaines binaires dans le code source en base6...

  • Spotlight on a career path: Paul, Business Development Consultant

    - by Maria Sandu
    I came to work for Oracle in November 2012 as a Customer Intelligence Representative and since then I was promoted to a Business Development Consultant, for Commercial Industries in the UK, based in Dublin. My background was primarily in Logistics, working for such companies as Indaver Ireland, Wincanton and P&O. I spent 10 years working in this industry and gained experience in negotiating with customers and suppliers in order to meet the needs of both, monitoring the quality and quantity of goods as well as the efficiency and organisation of the movement and storage of products. I decided to move from my logistics career in 2009 to study Information Technology in D.I.T. This was a challenge for me to move my career path; however the lectures at the college helped me significantly with the ability to understand how IT can have an effect on how businesses operate. Following on from college I came to work for Oracle. This also presented challenges but the training I received and the encouragement from management helped me understand that the same business rules apply no matter what background you come from. I have also learnt that using my past experience in working with customers and suppliers in Logistics has helped me understand how to meet customer’s needs. Oracle has offered me excellent training such as Sandler Sales Techniques and John Costigan. I continue to get all the training that I need to develop my career.

  • Linq to SQL and concurrency with Rob Conery repository pattern

    - by David Hall
    I have implemented a DAL using Rob Conery's spin on the repository pattern (from the MVC Storefront project) where I map database objects to domain objects using Linq and use Linq to SQL to actually get the data. This is all working wonderfully giving me the full control over the shape of my domain objects that I want, but I have hit a problem with concurrency that I thought I'd ask about here. I have concurrency working but the solution feels like it might be wrong (just one of those gitchy feelings). The basic pattern is: private MyDataContext _datacontext private Table _tasks; public Repository(MyDataContext datacontext) { _dataContext = datacontext; } public void GetTasks() { _tasks = from t in _dataContext.Tasks; return from t in _tasks select new Domain.Task { Name = t.Name, Id = t.TaskId, Description = t.Description }; } public void SaveTask(Domain.Task task) { Task dbTask = null; // Logic for new tasks omitted... dbTask = (from t in _tasks where t.TaskId == task.Id select t).SingleOrDefault(); dbTask.Description = task.Description, dbTask.Name = task.Name, _dataContext.SubmitChanges(); } So with that implementation I've lost concurrency tracking because of the mapping to the domain task. I get it back by storing the private Table which is my datacontext list of tasks at the time of getting the original task. I then update the tasks from this stored Table and save what I've updated This is working - I get change conflict exceptions raised when there are concurrency violations, just as I want. However, it just screams to me that I've missed a trick. Is there a better way of doing this? I've looked at the .Attach method on the datacontext but that appears to require storing the original version in a similar way to what I'm already doing. I also know that I could avoid all this by doing away with the domain objects and letting the Linq to SQL generated objects all the way up my stack - but I dislike that just as much as I dislike the way I'm handling concurrency.

  • Asp.Net MVC - Rob Conery's LazyList - Count() or Count

    - by Adam
    I'm trying to create an html table for order logs for customers. A customer is defined as (I've left out a lot of stuff): public class Customer { public LazyList<Order> Orders { get; set; } } The LazyList is set when fetching a Customer: public Customer GetCustomer(int custID) { Customer c = ... c.Orders = new LazyList<Order>(_repository.GetOrders().ByOrderID(custID)); return c; } The order log model: public class OrderLogTableModel { public OrderLogTableModel(LazyList<Order> orders) { Orders = orders; Page = 0; PageSize = 25; } public LazyList<Order> Orders { get; set; } public int Page { get; set; } public int PageSize { get; set; } } and I pass in the customer.Orders after loading a customer. Now the log i'm trying to make, looks something like: <table> <tbody> <% int rowCount = ViewData.Model.Orders.Count(); int innerRows = rowCount - (ViewData.Model.Page * ViewData.Model.PageSize); foreach (Order order in ViewData.Model.Orders.OrderByDescending(x => x.StartDateTime) .Take(innerRows).OrderBy(x => x.StartDateTime) .Take(ViewData.Model.PageSize)) { %> <tr> <td> <%= order.ID %> </td> </tr> <% } %> </tbody> </table> Which works fine. But the problem is evaluating ViewData.Model.Orders.Count() literally takes about 10 minutes. I've tried with the ViewData.Model.Orders.Count property instead, and the results are the same - takes forever. I've also tried calling _repository.GetOrders().ByCustomerID(custID).Count() directly from the view and that executes perfectly within a few ms. Can anybody see any reason why using the LazyList to get a simple count would take so long? It seems like its trying to iterate through the list when getting a simple count.

  • An MCM exam, Rob? Really?

    - by Rob Farley
    I took the SQL 2008 MCM Knowledge exam while in Seattle for the PASS Summit ten days ago. I wasn’t planning to do it, but I got persuaded to try. I was meaning to write this post to explain myself before the result came out, but it seems I didn’t get typing quickly enough. Those of you who know me will know I’m a big fan of certification, to a point. I’ve been involved with Microsoft Learning to help create exams. I’ve kept my certifications current since I first took an exam back in 1998, sitting many in beta, across quite a variety of topics. I’ve probably become quite good at them – I know I’ve definitely passed some that I really should’ve failed. I’ve also written that I don’t think exams are worth studying for. (That’s probably not entirely true, but it depends on your motivation. If you’re doing learning, I would encourage you to focus on what you need to know to do your job better. That will help you pass an exam – but the two skills are very different. I can coach someone on how to pass an exam, but that’s a different kind of teaching when compared to coaching someone about how to do a job. For example, the real world includes a lot of “it depends”, where you develop a feel for what the influencing factors might be. In an exam, its better to be able to know some of the “Don’t use this technology if XYZ is true” concepts better.) As for the Microsoft Certified Master certification… I’m not opposed to the idea of having the MCM (or in the future, MCSM) cert. But the barrier to entry feels quite high for me. When it was first introduced, the nearest testing centres to me were in Kuala Lumpur and Manila. Now there’s one in Perth, but that’s still a big effort. I know there are options in the US – such as one about an hour’s drive away from downtown Seattle, but it all just seems too hard. Plus, these exams are more expensive, and all up – I wasn’t sure I wanted to try them, particularly with the fact that I don’t like to study. I used to study for exams. It would drive my wife crazy. I’d have some exam scheduled for some time in the future (like the time I had two booked for two consecutive days at TechEd Australia 2005), and I’d make sure I was ready. Every waking moment would be spent pouring over exam material, and it wasn’t healthy. I got shaken out of that, though, when I ended up taking four exams in those two days in 2005 and passed them all. I also worked out that if I had a Second Shot available, then failing wasn’t a bad thing at all. Even without Second Shot, I’m much more okay about failing. But even just trying an MCM exam is a big effort. I wouldn’t want to fail one of them. Plus there’s the illusion to maintain. People have told me for a long time that I should just take the MCM exams – that I’d pass no problem. I’ve never been so sure. It was almost becoming a pride-point. Perhaps I should fail just to demonstrate that I can fail these things. Anyway – boB Taylor (@sqlboBT) persuaded me to try the SQL 2008 MCM Knowledge exam at the PASS Summit. They set up a testing centre in one of the room there, so it wasn’t out of my way at all. I had to squeeze it in between other commitments, and I certainly didn’t have time to even see what was on the syllabus, let alone study. In fact, I was so exhausted from the week that I fell asleep at least once (just for a moment though) during the actual exam. Perhaps the questions need more jokes, I’m not sure. I knew if I failed, then I might disappoint some people, but that I wouldn’t’ve spent a great deal of effort in trying to pass. On the other hand, if I did pass I’d then be under pressure to investigate the MCM Lab exam, which can be taken remotely (therefore, a much smaller amount of effort to make happen). In some ways, passing could end up just putting a bunch more pressure on me. Oh, and I did.

  • PASS Summit Feedback

    - by Rob Farley
    PASS Feedback came in last week. I also saw my dentist for some fillings... At the PASS Summit this year, I delivered a couple of regular sessions and a Lightning Talk. People told me they enjoyed it, but when the rankings came out, they showed that I didn’t score particularly well. Brent Ozar was keen to discuss it with me. Brent: PASS speaker feedback is out. You did two sessions and a Lightning Talk. How did you go? Rob: Not so well actually, thanks for asking. Brent: Ha! Sorry. Of course you know that's why I wanted to discuss this with you. I was in one of your sessions at SQLBits in the UK a month before PASS, and I thought you rocked. You've got a really good and distinctive delivery style.  Then I noticed your talks were ranked in the bottom quarter of the Summit ratings and wanted to discuss it. Rob: Yeah, I know. You did ask me if we could do this...  I should explain – my presentation style is not the stereotypical IT conference one. I throw in jokes, and try to engage the audience thoroughly. I find many talks amazingly dry, and I guess I try to buck that trend. I also run training courses, and find that I get a lot of feedback from people thanking me for keeping things interesting. That said, I also get feedback criticising me for my style, and that’s basically what’s happened here. For the rest of this discussion, let’s focus on my talk about the Incredible Shrinking Execution Plan, which I considered to be my main talk. Brent: I thought that session title was the very best one at the entire Summit, and I had it on my recommended sessions list.  In four words, you managed to sum up the topic and your sense of humor.  I read that and immediately thought, "People need to be in this session," and then it didn't score well.  Tell me about your scores. Rob: The questions on the feedback form covered the usefulness of the information, the speaker’s presentation skills, their knowledge of the subject, how well the session was described, the amount of time allocated, and the quality of the presentation materials. Brent: Presentation materials? But you don’t do slides.  Did they rate your thong? Rob: No-one saw my flip-flops in this talk, Brent. I created a script in Management Studio, and published that afterwards, but I think people will have scored that question based on the lack of slides. I wasn’t expecting to do particularly well on that one. That was the only section that didn’t have 5/5 as the most popular score. Brent: See, that sucks, because cookbook-style scripts are often some of my favorites.  Adam Machanic's Service Broker workbench series helped me immensely when I was prepping for the MCM.  As an attendee, I'd rather have a commented script than a slide deck.  So how did you rank so low? Rob: When I look at the scores that you got (based on your blog post), you got very few scores below 3 – people that felt strong enough about your talk to post a negative score. In my scores, between 5% and 10% were below 3 (except on the question about whether I knew my stuff – I guess I came as knowledgeable). Brent: Wow – so quite a few people really didn’t like your talk then? Rob: Yeah. Mind you, based on the comments, some people really loved it. I’d like to think that there would be a certain portion of the room who may have rated the talk as one of the best of the conference. Some of my comments included “amazing!”, “Best presentation so far!”, “Wow, best session yet”, “fantastic” and “Outstanding!”. I think lots of talks can be “Great”, but not so many talks can be “Outstanding” without the word losing its meaning. One wrote “Pretty amazing presentation, considering it was completely extemporaneous.” Brent: Extemporaneous, eh? Rob: Yeah. I guess they don’t realise how much preparation goes into coming across as unprepared. In many ways it’s much easier to give a written speech than to deliver a presentation without slides as a prompt. Brent: That delivery style, the really relaxed, casual, college-professor approach was one of the things I really liked about your presentation at SQLbits.  As somebody who presents a lot, I "get" it - I know how hard it is to come off as relaxed and comfortable with your own material.  It's like improv done by jazz players and comedians - if you've never tried it, you don't realize how hard it is.  People also don't realize how hard it is to make a tough subject fun. Rob: Yeah well... There will be people writing comments on this post that say I wasn't trying to make the subject fun, and that I was making it all about me. Sometimes the style works, sometimes it doesn't. Most of the comments mentioned the fact that I tell jokes, some in a nice way, but some not so much (and it wasn't just a PASS thing - that's the mix of feedback I generally get). One comment at PASS was: “great stand up comedian - not what I'm looking for at pass”, and there were certainly a few that said “too many jokes”. I’m not trying to do stand-up – jokes are my way of engaging with the audience while I demonstrate some of the amazing things that the Query Optimizer can do if you write your queries the right way. Some people didn’t think it was technical enough, but I’ve also had some people tell me that the concepts I’m explaining are deep and profound. Brent: To me, that's a hallmark of a great explanation - when someone says, "But of course it has to work that way - how could it work any other way?  It seems so simple and logical."  Well, sure it does when it's explained correctly, but now pick up any number of thick SQL Server books and try to understand the Redundant Joins concept.  I guarantee it'll take more than 45 minutes. Rob: Some people in my audiences realise that, but definitely not everyone. There's only so much you can tell someone that something is profound. Generally it's something that they either have an epiphany on or not. I like to lull my audience into knowing what's going on, and do something that surprises them. Gain their trust, build a rapport, and then show them the deeper truth of what just happened. Brent: So you've learned your lesson about presentation scores, right?  From here on out, you're going to be dry, humorless, and all your presentations will consist of you reading bullet points off the screen. Rob: No Brent, I’m not. I'm also not going to suggest that most presentations at PASS are like that. No-one tries to present like that. There's a big space to occupy between what "dry and humourless" and me. My difference is to focus on the relationship I have with the crowd, rather than focussing on delivering the perfect session. I want to see people smiling and know they're relaxed. I think most presenters focus on the material, which is completely reasonable and safe. I remember once hearing someone talking about product creation. They talked about mediocrity. They said that one of the worst things that people can ever say about your product is that it’s “good”. What you want is for 10% of the world to love it enough to want to buy it. If 10% the world gave me a dollar, I’d have more money than I could ever use (assuming it wasn’t the SAME dollar they were giving me I guess). Brent: It's the Raving Fans theory.  It's better to have a small number of raving customers than a large number of almost-but-not-really customers who don't care that much about your product or service.  I know exactly how you feel - when I got survey feedback from my Quest video presentation when I was dressed up in a Richard Simmons costume, some of the attendees said I was unprofessional and distracting.  Some of the attendees couldn't get enough and Photoshopped all kinds of stuff into the screen captures.  On a whole, I probably didn't score that well, and I'm fine with that.  It sucks to look at the scores though - do those lower scores bother you? Rob: Of course they do. It hurts deeply. I open myself up and give presentations in a very personal way. All presenters do that, and we all feel the pain of negative feedback. I hate coming 146th & 162nd out of 185, but have to acknowledge that many sessions did worse still. Plus, once I feel the wounds have healed, I’ll be able to remember that there are people in the world that rave about my presentation style, and figure that people will hopefully talk about me. One day maybe those people that don’t like my presentation style will stay away and I might be able to score better. You don’t pay to hear country music if you prefer western... Lots of people find chili too spicy, but it’s still a popular food. Brent: But don’t you want to appeal to everyone? Rob: I do, but I don’t want to be lukewarm as in Revelation 3:16. I’d rather disgust and be discussed. Well, maybe not ‘disgust’, but I don’t want to conform. Conformity just isn’t the same any more. I’m not sure I’ve ever been one to do that. I try not to offend, but definitely like to be different. Brent: Count me among your raving fans, sir.  Where can we see you next? Rob: Considering I live in Adelaide in Australia, I’m not about to appear at anyone’s local SQL Saturday. I’m still trying to plan which events I’ll get to in 2011. I’ve submitted abstracts for TechEd North America, but won’t hold my breath. I’m also considering the SQLBits conferences in the UK in April, PASS in October, and I’m sure I’ll do some LiveMeeting presentations for user groups. Online, people download some of my recent SQLBits presentations at http://bit.ly/RFSarg and http://bit.ly/Simplification though. And they can download a 5-minute MP3 of my Lightning Talk at http://www.lobsterpot.com.au/files/Collation.mp3, in which I try to explain the idea behind collation, using thongs as an example. Brent: I was in the audience for http://bit.ly/RFSarg. That was a great presentation. Rob: Thanks, Brent. Now where’s my dollar?

  • "Sent on behalf" not appearing when delegates sending mails

    - by New Steve
    Ringo is a delegate of Paul's mailbox in Exchange, but when Ringo sends mail from Paul's mailbox, the recipient sees "Paul" in the sender field, rather than "Paul Sent On Behalf Of Ringo" Paul has set "Editor" permissions for Ringo to his mailbox, and Ringo has been granted "Send on behalf of" permissions in Exchange. Ringo did at one time have "Send As" permissions for Paul's mailbox in Exchange, but this has since been removed. This is also the case for all other delegates to Paul's mailbox. How do I make it so that emails sent by Paul's delegates show the "Sent On Behalf Of" information in the Sender field? Using Exchange Server 2007 and Microsoft Office Outlook 2007

  • Building a project in VS that depends on a static and dynamic library

    - by fg nu
    Noob noobin'. I would appreciate some very careful handholding in setting up an example in Visual Studio 2010 Professional where I am trying to build a project which links: a previously built static library, for which the VS project folder is "C:\libjohnpaul\" a previously built dynamic library, for which the VS project folder is "C:\libgeorgeringo\" These are listed as Recipes 1.11, 1.12 and 1.13 in the C++ Cookbook. The project fails to compile for me with unresolved dependencies (see details below), and I can't figure out why. Project 1: Static Library The following are the header and source files that were compiled in this project. I was able to compile this project fine in VS2010, to the named standard library "libjohnpaul.lib" which lives in the folder ("C:/libjohnpaul/Release/"). // libjohnpaul/john.hpp #ifndef JOHN_HPP_INCLUDED #define JOHN_HPP_INCLUDED void john( ); // Prints "John, " #endif // JOHN_HPP_INCLUDED // libjohnpaul/john.cpp #include <iostream> #include "john.hpp" void john( ) { std::cout << "John, "; } // libjohnpaul/paul.hpp #ifndef PAUL_HPP_INCLUDED #define PAUL_HPP_INCLUDED void paul( ); // Prints " Paul, " #endif // PAUL_HPP_INCLUDED // libjohnpaul/paul.cpp #include <iostream> #include "paul.hpp" void paul( ) { std::cout << "Paul, "; } // libjohnpaul/johnpaul.hpp #ifndef JOHNPAUL_HPP_INCLUDED #define JOHNPAUL_HPP_INCLUDED void johnpaul( ); // Prints "John, Paul, " #endif // JOHNPAUL_HPP_INCLUDED // libjohnpaul/johnpaul.cpp #include "john.hpp" #include "paul.hpp" #include "johnpaul.hpp" void johnpaul( ) { john( ); paul( ); Project 2: Dynamic Library Here are the header and source files for the second project, which also compiled fine with VS2010, and the "libgeorgeringo.dll" file lives in the directory "C:\libgeorgeringo\Debug". // libgeorgeringo/george.hpp #ifndef GEORGE_HPP_INCLUDED #define GEORGE_HPP_INCLUDED void george( ); // Prints "George, " #endif // GEORGE_HPP_INCLUDED // libgeorgeringo/george.cpp #include <iostream> #include "george.hpp" void george( ) { std::cout << "George, "; } // libgeorgeringo/ringo.hpp #ifndef RINGO_HPP_INCLUDED #define RINGO_HPP_INCLUDED void ringo( ); // Prints "and Ringo\n" #endif // RINGO_HPP_INCLUDED // libgeorgeringo/ringo.cpp #include <iostream> #include "ringo.hpp" void ringo( ) { std::cout << "and Ringo\n"; } // libgeorgeringo/georgeringo.hpp #ifndef GEORGERINGO_HPP_INCLUDED #define GEORGERINGO_HPP_INCLUDED // define GEORGERINGO_DLL when building libgerogreringo.dll # if defined(_WIN32) && !defined(__GNUC__) # ifdef GEORGERINGO_DLL # define GEORGERINGO_DECL _ _declspec(dllexport) # else # define GEORGERINGO_DECL _ _declspec(dllimport) # endif # endif // WIN32 #ifndef GEORGERINGO_DECL # define GEORGERINGO_DECL #endif // Prints "George, and Ringo\n" #ifdef __MWERKS__ # pragma export on #endif GEORGERINGO_DECL void georgeringo( ); #ifdef __MWERKS__ # pragma export off #endif #endif // GEORGERINGO_HPP_INCLUDED // libgeorgeringo/ georgeringo.cpp #include "george.hpp" #include "ringo.hpp" #include "georgeringo.hpp" void georgeringo( ) { george( ); ringo( ); } Project 3: Executable that depends on the previous libraries Lastly, I try to link the aforecompiled static and dynamic libraries into one project called "helloBeatlesII" which has the project directory "C:\helloBeatlesII" (note that this directory does not nest the other project directories). The linking process that I did is described below: To the "helloBeatlesII" solution, I added the solutions "libjohnpaul" and "libgeorgeringo"; then I changed the properties of the "helloBeatlesII" project to additionally point to the include directories of the other two projects on which it depends ("C:\libgeorgeringo\libgeorgeringo" & "C:\libjohnpaul\libjohnpaul"); added "libgeorgeringo" and "libjohnpaul" to the project dependencies of the "helloBeatlesII" project and made sure that the "helloBeatlesII" project was built last. Trying to compile this project gives me the following unsuccessful build: 1------ Build started: Project: helloBeatlesII, Configuration: Debug Win32 ------ 1Build started 10/13/2012 5:48:32 PM. 1InitializeBuildStatus: 1 Touching "Debug\helloBeatlesII.unsuccessfulbuild". 1ClCompile: 1 helloBeatles.cpp 1ManifestResourceCompile: 1 All outputs are up-to-date. 1helloBeatles.obj : error LNK2019: unresolved external symbol "void __cdecl georgeringo(void)" (?georgeringo@@YAXXZ) referenced in function _main 1helloBeatles.obj : error LNK2019: unresolved external symbol "void __cdecl johnpaul(void)" (?johnpaul@@YAXXZ) referenced in function _main 1E:\programming\cpp\vs-projects\cpp-cookbook\helloBeatlesII\Debug\helloBeatlesII.exe : fatal error LNK1120: 2 unresolved externals 1 1Build FAILED. 1 1Time Elapsed 00:00:01.34 ========== Build: 0 succeeded, 1 failed, 2 up-to-date, 0 skipped ========== At this point I decided to call in the cavalry. I am new to VS2010, so in all likelihood I am missing something straightforward.

  • Taking the Plunge - or Dipping Your Toe - into the Fluffy IAM Cloud by Paul Dhanjal (Simeio Solutions)

    - by Greg Jensen
    In our last three posts, we’ve examined the revolution that’s occurring today in identity and access management (IAM). We looked at the business drivers behind the growth of cloud-based IAM, the shortcomings of the old, last-century IAM models, and the new opportunities that federation, identity hubs and other new cloud capabilities can provide by changing the way you interact with everyone who does business with you. In this, our final post in the series, we’ll cover the key things you, the enterprise architect, should keep in mind when considering moving IAM to the cloud. Invariably, what starts the consideration process is a burning business need: a compliance requirement, security vulnerability or belt-tightening edict. Many on the business side view IAM as the “silver bullet” – and for good reason. You can almost always devise a solution using some aspect of IAM. The most critical question to ask first when using IAM to address the business need is, simply: is my solution complete? Typically, “business” is not focused on the big picture. Understandably, they’re focused instead on the need at hand: Can we be HIPAA compliant in 6 months? Can we tighten our new hire, employee transfer and termination processes? What can we do to prevent another password breach? Can we reduce our service center costs by the end of next quarter? The business may not be focused on the complete set of services offered by IAM but rather a single aspect or two. But it is the job – indeed the duty – of the enterprise architect to ensure that all aspects are being met. It’s like remodeling a house but failing to consider the impact on the foundation, the furnace or the zoning or setback requirements. While the homeowners may not be thinking of such things, the architect, of course, must. At Simeio Solutions, the way we ensure that all aspects are being taken into account – to expose any gaps or weaknesses – is to assess our client’s IAM capabilities against a five-step maturity model ranging from “ad hoc” to “optimized.” The model we use is similar to Capability Maturity Model Integration (CMMI) developed by the Software Engineering Institute (SEI) at Carnegie Mellon University. It’s based upon some simple criteria, which can provide a visual representation of how well our clients fair when evaluated against four core categories: ·         Program Governance ·         Access Management (e.g., Single Sign-On) ·         Identity and Access Governance (e.g., Identity Intelligence) ·         Enterprise Security (e.g., DLP and SIEM) Often our clients believe they have a solution with all the bases covered, but the model exposes the gaps or weaknesses. The gaps are ideal opportunities for the cloud to enter into the conversation. The complete process is straightforward: 1.    Look at the big picture, not just the immediate need – what is our roadmap and how does this solution fit? 2.    Determine where you stand with respect to the four core areas – what are the gaps? 3.    Decide how to cover the gaps – what role can the cloud play? Returning to our home remodeling analogy, at some point, if gaps or weaknesses are discovered when evaluating the complete impact of the proposed remodel – if the existing foundation wouldn’t support the new addition, for example – the owners need to decide if it’s time to move to a new house instead of trying to remodel the old one. However, with IAM it’s not an either-or proposition – i.e., either move to the cloud or fix the existing infrastructure. It’s possible to use new cloud technologies just to cover the gaps. Many of our clients start their migration to the cloud this way, dipping in their toe instead of taking the plunge all at once. Because our cloud services offering is based on the Oracle Identity and Access Management Suite, we can offer a tremendous amount of flexibility in this regard. The Oracle platform is not a collection of point solutions, but rather a complete, integrated, best-of-breed suite. Yet it’s not an all-or-nothing proposition. You can choose just the features and capabilities you need using a pay-as-you-go model, incrementally turning on and off services as needed. Better still, all the other capabilities are there, at the ready, whenever you need them. Spooling up these cloud-only services takes just a fraction of the time it would take a typical organization to deploy internally. SLAs in the cloud may be higher than on premise, too. And by using a suite of software that’s complete and integrated, you can dramatically lower cost and complexity. If your in-house solution cannot be migrated to the cloud, you might consider using hardware appliances such as Simeio’s Cloud Interceptor to extend your enterprise out into the network. You might also consider using Expert Managed Services. Cost is usually the key factor – not just development costs but also operational sustainment costs. Talent or resourcing issues often come into play when thinking about sustaining a program. Expert Managed Services such as those we offer at Simeio can address those concerns head on. In a cloud offering, identity and access services lend to the new paradigms described in my previous posts. Most importantly, it allows us all to focus on what we're meant to do – provide value, lower costs and increase security to our respective organizations. It’s that magic “silver bullet” that business knew you had all along. If you’d like to talk more, you can find us at simeiosolutions.com.

  • Grant a user access to directories shared by root (mod: 770)

    - by Paul Dinham
    I want to grant a user (username: paul) access to all directories shared by root with mod 770. I do it this way: groups root (here comes a list of groups in which root user is) usermod -a -G group1 paul usermod -a -G group2 paul usermod -a -G group3 paul ... All the 'group1', 'group2', 'group3' are seen in the group list of root user. However, after adding 'paul' to all groups above, he still can not write to directories shared by root user with mod 770. Did I do it wrongly?

  • SQL Server Master class winner

    - by Testas
     The winner of the SQL Server MasterClass competition courtesy of the UK SQL Server User Group and SQL Server Magazine!    Steve Hindmarsh     There is still time to register for the seminar yourself at:  www.regonline.co.uk/kimtrippsql     More information about the seminar     Where: Radisson Edwardian Heathrow Hotel, London  When: Thursday 17th June 2010  This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will: Debunk many of the ingrained misconceptions around SQL Server's behaviour    Show you disaster recovery techniques critical to preserving your company's life-blood - the data    Explain how a common application design pattern can wreak havoc in the database Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to change  Sessions Abstracts  KEYNOTE: Bridging the Gap Between Development and Production    Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong.   SESSION ONE: SQL Server Mythbusters  It's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained.   SESSION TWO: Database Recovery Techniques Demo-Fest  Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted!   SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward   Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys!   SESSION 4: Essential Database Maintenance  In this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies     Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor. Kimberly worked on the SQL Server team in the early 1990s as a tester and writer before leaving to found SQLskills and embrace her passion for teaching and consulting. Kimberly has been a staple at worldwide conferences since she first presented at TechEd in 1996, and she blogs at SQLskills.com/blogs/Kimberly. They have written Microsoft whitepapers and books for SQL Server 2000, 2005 and 2008, and are regular, top-rated presenters worldwide on database maintenance, high availability, disaster recovery, performance tuning, and SQL Server internals. Together they teach the SQL MCM certification and throughout Microsoft.In their spare time, they like to find frogfish in remote corners of the world.   Speaker Testimonials  "To call them good trainers is an epic understatement. They know how to deliver technical material in ways that illustrate it well. I had to stop Paul at one point and ask him how long it took to build a particular slide because the animations were so good at conveying a hard-to-describe process." "These are not beginner presenters, and they put an extreme amount of preparation and attention to detail into everything that they do. Completely, utterly professional." "When it comes to the instructors themselves, Kimberly and Paul simply have no equal. Not only are they both ultimate authorities, but they have endless enthusiasm about the material, and spot on delivery. If either ever got tired they never showed it, even after going all day and all week. We witnessed countless demos over the course of the week, some extremely involved, multi-step processes, and I can’t recall one that didn’t go the way it was supposed to." "You might think that with this extreme level of skill comes extreme levels of egotism and lack of patience. Nothing could be further from the truth. ... They simply know how to teach, and are approachable, humble, and patient." "The experience Paul and Kimberly have had with real live customers yields a lot more information and things to watch out for than you'd ever get from documentation alone." “Kimberly, I just wanted to send you an email to let you know how awesome you are! I have applied some of your indexing strategies to our website’s homegrown CMS and we are experiencing a significant performance increase. WOW....amazing tips delivered in an exciting way!  Thanks again”

  • How do I stop Python install on Mac OS X from putting things in my home directory?

    - by Rob
    Hi, I'm trying to install Python from source on my Mac. (OS X 10.6.2, Python-2.6.5.tar.bz2) I've done this before and it was easy, but for some reason, this time after ./configure, and make, the sudo make install puts things some things in my home directory instead of in /usr/local/... where I expect. The .py files are okay, but not the .so files... RobsMac Python-2.6.5 $ sudo make install [...] /usr/bin/install -c -m 644 ./Lib/anydbm.py /usr/local/lib/python2.6 /usr/bin/install -c -m 644 ./Lib/ast.py /usr/local/lib/python2.6 /usr/bin/install -c -m 644 ./Lib/asynchat.py /usr/local/lib/python2.6 [...] running build_scripts running install_lib creating /Users/rob/Library/Python creating /Users/rob/Library/Python/2.6 creating /Users/rob/Library/Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_AE.so - /Users/rob/Library/ Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_AH.so - /Users/rob/Library/ Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_App.so - /Users/rob/Library/ Python/2.6/site-packages [...] Later, this causes imports that require those .so files to fail. For example... RobsMac Python-2.6.5 $ python Python 2.6.5 (r265:79063, Apr 28 2010, 13:40:18) [GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import zlib Traceback (most recent call last):     File "", line 1, in ImportError: No module named zlib Any ideas what is wrong? thanks, Rob

  • Two network adapters on Ubuntu Server 9.10 - Can't have both working at once?

    - by Rob
    I'm trying to set up two network adapters in Ubuntu (server edition) 9.10. One for the public internet, the other a private LAN. During the install, I was asked to pick a primary network adapter (eth0 or eth1). I chose eth0, gave the installer the details listed below in the contents of /etc/network/interfaces, and carried on. I've been using this adapter with these setting for the last few days, and every thing's been fine. Today, I decide it's time to set up the local adapter. I edit the /etc/network/interfaces to add the details for eth1 (see below), and restart networking with sudo /etc/init.d/networking restart. After this, attempting to ping the machine using it's external IP address fails, but I can ping it's local IP address. If I bring eth1 down using sudo ifdown eth1, I can successfully ping the machine via it's external IP address again (but obviously not it's internal IP address). Bringing eth1 back up returns us to the original problem state: external IP not working, internal IP working. Here's my /etc/network/interfaces (I've removed the external IP information, but these settings are unchanged from when it worked) rob@rhea:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary (public) network interface auto eth0 iface eth0 inet static address xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx network xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx gateway xxx.xxx.xxx.xxx # The secondary (private) network interface auto eth1 iface eth1 inet static address 192.168.99.4 netmask 255.255.255.0 network 192.168.99.0 broadcast 192.168.99.255 gateway 192.168.99.254 I then do this: rob@rhea:~$ sudo /etc/init.d/networking restart * Reconfiguring network interfaces... [ OK ] rob@rhea:~$ sudo ifup eth0 ifup: interface eth0 already configured rob@rhea:~$ sudo ifup eth1 ifup: interface eth1 already configured Then, from another machine: C:\Documents and Settings\Rob>ping [external ip] Pinging [external ip] with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for [external ip]: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), Back on the Ubuntu server in question: rob@rhea:~$ sudo ifdown eth1 ... and again on the other machine: C:\Documents and Settings\Rob>ping [external ip] Pinging [external ip] with 32 bytes of data: Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Reply from [external ip]: bytes=32 time<1ms TTL=63 Ping statistics for [external ip]: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms So... what am I doing wrong?
