  • Best practice for Exchange 2010 HA topology considering 6 x Exchange licenses and TMG 2010

    - by MadBoy
    What would be best topology considering that: 6 x Exchange 2010 Standard Licenses 2 x Separate locations that are supposed to support redundancy in case of link problems 4 x Forefront TMG 2010 with Forefront Security and Forefront Protection/Security Multiple locations worldwide using those Exchange. Most locations will be connected with VPN Tunnel (the ones hosting Exchange for sure). I was thinking something like this: Location MAIN (about 70-100 people): 2x TMG 2010 in NLB 1x Exchange 2010 CAS/HUB Role 2x Exchange 2010 Mailbox Role (Active + Passive) Location SUPPORT (about 20 people): 2x TMG 2010 in NLB 1x Exchange 2010 CAS/HUB Role 2x Exchange 2010 Mailbox Role (Active + Passive) Management wants to make sure that in case of problems in main location (power failure, link loss etc) second location can support all traffic from around the world and vice-versa. We have 6-7 locations and more comming up (not big ones but like 10+ people per each location). I do know that CAS/HUB is single point of failure (and no NLB), but i simply lack more licenses to do some redundancy on that. What do you think about this approach? What would be better approach according to you?

  • Is there a pattern or best practice for passing a reference type to multiple classes vs a static class?

    - by Dave
    My .NET application creates HTML files, and as such, the structure looks like variable myData BuildHomePage() variable graph = new BuildGraphPage(myData) variable table = BuildTablePage(myData) BuildGraphPage and BuildTablePage both require access data, the myData object. In the above example, I've passed the myData object to 2 constructors. This is what I'm doing now, in my current project. The myData object, and it's properties are all readonly. The problem is, the number of pages which will require this object has grown. In the real project, there are currently 4, but the new spec is to have about 20. Passing this object to the constructor of each new object and assigning it to a field is a little time consuming, but not a hardship! This poses the question whether it's better practice to continue as I have, or to refactor and create a new static class for myData which can be referenced from any where in my project. I guess my abilities to use Google are poor, because I did try and find an appropriate pattern as I am sure this type of design must be common place but my results returned nothing. Is there a pattern which is suited, or do best practices lean towards one implementation over another.

  • What is the best approach for inline code comments?

    - by d1egoaz
    We are doing some refactoring to a 20 years old legacy codebase, and I'm having a discussion with my colleague about the comments format in the code (plsql, java). There is no a default format for comments, but in most cases people do something like this in the comment: // date (year, year-month, yyyy-mm-dd, dd/mm/yyyy), (author id, author name, author nickname) and comment the proposed format for future and past comments that I want is: // {yyyy-mm-dd}, unique_author_company_id, comment My colleague says that we only need the comment, and must reformat all past and future comments to this format: // comment My arguments: I say for maintenance reasons, it's important to know when and who did a change (even this information is in the SCM). The code is living, and for that reason has a history. Because without the change dates it's impossible to know when a change was introduced without open the SCM tool and search in the long object history. because the author is very important, a change of authors is more credible than a change of authory Agility reasons, no need to open and navigate through the SCM tool people would be more afraid to change something that someone did 15 years ago, than something that was recently created or changed. etc. My colleague's arguments: The history is in the SCM Developers must not be aware of the history of the code directly in the code Packages gets 15k lines long and unstructured comments make these packages harder to understand What do you think is the best approach? Or do you have a better approach to solve this problem?

  • What is the best way to track / record the current programming project you work on? [duplicate]

    - by user2424160
    This question already has an answer here: Methodology for Documenting Existing Code Base 6 answers When do you start documenting the code? 13 answers Where should a programmer explain the extended logic behind the code? 5 answers I have been in this problem for long time and I want to know how it's done in real / big companies project? Suppose I have the project to build a website. Now I divide the project into sub tasks and do it. But you know that suppose I have task1 in hand like export the page to pdf. Now I spend 3 days to do that , came across various problems, many Stack Overflow questions and in the end I solve it. Now 4 months after someone told me that there is some error in the code. Now by that I completely forgot about (60%) of how I did it and why I do this way. I document the code but I can't write the whole story of that in the code. Then I have to spend much time on code to find what was the problem so that I added this line etc. I want to know that is there any way that i can log steps in completing the project. So that I can see how I end up with code, what errors I got, what questions I asked on SO and etc. How people do it in real time? Which software to use? I know in our project management software called JIRA we have tasks but that does not cover what steps I took to solve that tasks. What is the best way so that when I look back at my 2 year old project, I know how I solve particular task?

  • How to organize a large number of objects

    - by shane
    We have a large number of documents and metadata (xml files) associated with these documents. What is the best way to organize them? Currently we put them into a series of nested folders: /repository/category/date(when they were loaded into our db)/document_number.pdf and .xml We use the path as a unique identifier for the document in our system. This is more versatile than putting them all in a single flat folder. also it is independent from our database/application, so we can reload them in case of failure. Yet, it introduces some limitations. for example we can't move the files once they've been placed in this structure, also it takes work to put them this way. What is the best practice? How websites such as Scribd deal with this problem?

  • Best approach for coding ?

    - by ahmed
    What should or how should I decide the best approach for coding as a smart programmer. I have just started programming last year in VB, and I keep on listening this statement. But I never could find by myself to choose the best approach for coding. When I search for a coding example on internet I find different types of approach to achieve the same target. So help me finding the best approach. (asp.net,vb.net)

  • Best way to handle global state

    - by David
    Hi there, I was wondering if anyone could offer some advice on 'best practices' for using global state in a web application - specifically PHP, although im looking for generic best practices i.e. design patterns etc. At the moment I just use a static class, calling it Configs. I suppose this is similar to using the registry pattern but surely there is a more elegant way of handling global data within an application - i just cant think of a better way though.

  • best practice to removing DC from Site that no longer connects via vpn in another city

    - by dasko
    hi i am looking for a recap of what i have done already to see if i missed anything. i had two cities connected by wan using a ipsec persistent tunnel between gateways. i had one DC (DOMAIN CONTROLLER) in each city that was a global catalog server (GC) they were set up to replicate and i had them configured under Sites and Servers with their own subnet etc... about 6 months ago the one city was removed and i was not able to gracefully remove, through dcpromo, the server that was there. it is no longer used and cannot be brought back. the company went from two sites down to single site. Problem is i had a whole bunch of kcc errors and replication bugs in the event viewer. i wanted to clean up my active directory and decided to use the ntdsutil metadata cleanup commands. i removed the server from the specifed site based on a procedure from petri website. I then removed the instances of the old DC and site from Sites and Servers. Then i went and cleaned up the DNS by removing Host A records, NS server name from both the local DNS forward lookup zone and the _msdcs i also removed the reverse lookup zone for the subnet that no longer exists. is there anything i missed? thanks in advance for any help. gd

  • Best way to override 1024 process ulimit

    - by CamelBlues
    On CentOS distros, there is an /etc/security/limits.d/90-noproc.conf that sets a process limit for all users: # Default limit for number of user's processes to prevent # accidental fork bombs. # See rhbz #432903 for reasoning. * soft nproc 1024 I'd like to keep this limit in there, but allow one user to have more than 1024 processes. Because of how the server is puppetized, I'm unable to use the built-in bash ulimit command.

  • automated email downloading and treading similar messages

    - by Michael
    Okay here it is : I have built an c# console app that downloads email, save attachments , and stores the subject, from, to, body to a MS SQL Database. I use aspNetPOP3 Component to do this. I have build a front end ASP.NET application to search and view the messages. Works great. Next Steps (this is where I need help ): Now I want my users (of the asp.net app) to reply to this message send the email to the originator, and tread any additional replies back and forth on from that original message(like basecamp). This would allow my end user not to have to log-in to a system, they just continue using email (our users can as well). The question is what should I use to determine if messages are related? Subject line I think is a bad approach. I believe the best method i've seen so far is way basecamp does it, but I'm not sure how that is done, here is a real example of the reply to address from a basecamp email (I've changed the host name): [email protected] Basecamp obviously are prefixing the pre-pending a tracking id to the email address, however , when I try this with my mail service, it's rejected. Is this the best approach, is there a way I can accomplish this, is there a better approach, or even a better email component tool? Thanks, Mike

  • Leveraging Microsoft Patterns and Practices

    - by Tim Murphy
    I want to bring the Patterns and Practices group to the attention of those who have not already been exposed.  I have been a fan of the P&P team since they came out with the original Application Blocks which eventually turned into the Enterprise Library.  Their main purpose is to assemble guidance and tools that make it easier for all of us to build amazing solutions.  I would simply suggest you spend some time exploring the information and code libraries that they have produced.  Free resources are always a great find and I have used a number of the P&P solutions over the years with success.  If nothing else you may find some new ideas.  Enjoy. http://msdn.microsoft.com/en-us/practices/                           del.icio.us Tags: Patterns and Practices,Microsoft,Architecture,software development

  • [Principles] Concrete Type or Interface for method return type?

    - by SDReyes
    In general terms, whats the better election for a method's return type: a concrete type or an interface? In most cases, I tend to use concrete types as the return type for methods. because I believe that an concrete type is more flexible for further use and exposes more functionality. The dark side of this: Coupling. The angelic one: A concrete type contains per-se the interface you would going to return initially, and extra functionality. What's your thumb's rule? Is there any programming principle for this? BONUS: This is an example of what I mean http://stackoverflow.com/questions/491375/readonlycollection-or-ienumerable-for-exposing-member-collections

  • What is the python "with" statement designed for?

    - by fmark
    I came across the Python with statement for the first time today. I've been using Python lightly for several months and didn't even of its existence! Given its somewhat obscure status, I thought it would be worth asking: What is the Python with statement designed to be used for? What do you use it for? Are their any gotchas I need to be aware of, or common anti-patterns associated with its use?
