  • Bing brings Twitter aggregation to search results

    - by jamiet
    I read with interest today a post on the Bing blog Get the Latest on Twitter with Bing Social Search which describes how tweets are soon going to show up in Bing search results. On the surface that isn’t very interesting, Google has been doing this for a while, but of particular interest to myself was the following screenshot: We can see at the bottom of a search result for “TMZ” that Bing is showing us the most popular TMZ stories as determined by the number of tweets that contain links to them. This is great. Bing are applying a principle that those of us in the Business Intelligence (BI) trade have known for ages: a piece of data in isolation is not very interesting but when you aggregate a lot of that data you find the trends that actually matter and when you surface that data in a meaningful way then people can derive real value from it. That sounds obvious but this new Bing feature is the first time I have seen the principle applied in a useful way to tweets and I applaud them for that; its certainly a lot more useful than the pointless constant tweet scroll that you see on Google. What a shame its going to be, yet again from Bing, a US-only feature. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • VirtualBox 4.1.20 (Windows 7 / Ubuntu 12.04 (32 bit)) copy/paste is broken

    - by user1628257
    I have a Windows 7 Pro host, and Ubuntu 12.04 LTS guest. I cannot get the shared clipboard working. I have installed Guest Additions 4.1.20 on VirtualBox 4.1.20, have restarted, followed instructions found at http://www.virtualbox.org/manual/ch04.html#idp18411760, and have enabled bidirectional clipboard sharing within VirtualBox options. However, I still cannot copy and paste between the host and guest. Copy/paste works great within the host, and within the guest, but not between the two. I'm out of ideas.

  • Problem running mercurial against symlinked .hgrc file under Cygwin/Windows 7

    - by emptyset
    This is not a question about handling symlinks in the mercurial repository. I have this setup at work where I keep my dotfiles in a separate directory (.configuration) that I can use to synch my dotfiles between cygwin/windows and linux, then use symlinks instead of dotfiles in the home directory. So, I have the symlink ~/.hgrc -> .configuration/.hgrc in my home directory. After setting this up, mercurial complains thus: $ hg st hg: config error at C:\Users\aaf\.hgrc:1: '!<symlink>ÿþ.configuration/.hgrc' Removing the symlink and replacing it with the actual file works, so the contents of the .hgrc file are not at fault. I can live with that, I suppose, but I'd like to know why this happens. All other tools I've configured the same way work great with symlinked dotfiles.

  • Average SPA weight [on hold]

    - by Emmanuel Istace
    First, sorry my noobs questions, but I'm mainly Windows Developer and not Web Developer :) I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA ? As this is the whole website, do you think it's acceptable ? Is lazy load (for images) a solution ? What will be impact for SEO ? Is the "200kb rule" of google still relevant ? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs ? Can a caching strategy be an answer ? Thank you in advance for you help ! Best regards

  • Windows 7 Connection Sharing unable to access some sites

    - by Kristopher Ives
    I have a pretty sad networking situation that involves connecting to an open Wireless network and sharing that connection to an Ethernet that is plugged into a Linksys router. This has been done with XP and Windows 7, and it works great with XP. The problem with Windows 7 is that only some DNS will work. I don't know if it's been poisoned on the network above us (which we have no control over), but we've tried clearing the DNS cache as well as moving to using Google's DNS servers (8.8.8.8, 8.8.4.4). Here is a really quick list of sites that won't respond to DNS requests at all via dig, although if I get the IP address I can ping them: facebook.com yuilibrary.com twitter.com A lot of sites do work though. Anyone have an idea? It may be a subnet problem? If anyone wants more info let me know.

  • Local network cache of PHP and Apache2 on Win Server 2008 R2

    - by Ahmed Benlahsen
    Software configuration : I have a new server with Windows Server 2008 R2 installed via VMWare. I have installed Apache2.2, PHP5.2 and MySQL5.5 as separate packages. Issue : On my first installation of my application, all works great. When I updated some JS and CSS files and accessed my application again from a PC on local network, I got the old JS and CSS versions. When I access the same application on local server I got the latest versions of those files. Link of my application on local server is : http://localhost/BADIL Link of my application from local network is : http://LOCAL_SERVER_IP/BADIL I think that must be some cache but I don't know where. Maybe on Win Server 2008 R2 or on VMWare? The question is: Why, when I access my application on the server, everything works fine, but when I access the same application from a local network, I do not see the updated versions of JS and CSS files?

  • What You Said: Your Favorite Co-Op Games

    - by Jason Fitzpatrick
    While competitive gaming is fun, reader response to this week’s Ask the Readers question shows that good old beat-the-bad-guys-together cooperative gaming is as popular as ever. Read on to see what your fellow readers are playing. By far the most popular nomination for favorite co-op game was an outright classic: 1987′s smash hit Contra. Originally released as an arcade game, it was ported to the Nintendo Entertainment System in 1988. Contra was groundbreaking for the time as it featured simultaneous play for the two players–you and a friend could play side by side without waiting to take your turn. Clearly that kind of side-by-side play resonated with readers. RJ writes: When my fiance and I played and beat Contra on the NES. I knew she was the one and we got married and its been great. That’s no small feat; Contra was voted “Toughest Game to Beat” by IGN.com readers. Even readers who had moved on to newer games still recall Contra fondly; Jami writes: The Gears of War trilogy on 360 is my favorite co-op currently, although I do have fond memories of bonding with my brother playing some co-op Contra on the NES.

  • jQuery dialog open causes page to continuously lengthen in IE [closed]

    - by Michael
    I made my first dialog and AJAX work in jQuery and finally got everything working great - the dialog has a few buttons, cancel, save, and generate to get a new random string from the server. The problem is when I make the dialog modal (graying out the rest of the window), then in IE the scrollbars appear and sometimes keep moving as the page continuously extends down. This happens whenever the dialog is opened (it's not initially set to open) but not everytime. I can't think of any part of my code that would do this as I don't even have a JS loop anywhere. Googling for this didn't help. It seems like an IE vs jQuery quirk but any ideas?

  • How should I configure TRIM Support for LVM logical volumes?

    - by Zack Perry
    I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space. I plan to use the remaining for logical volumes for KVM guests, all run Ubuntu 12.04 Server I would like to ensure that the SSD is utilized optimally. Although on this site, there are some great info about setting up TRIM support for file system setups that do not involve LVM, I have not found explicit guide regarding my planned setup. I did found this page which talks about adding issue_discards in /etc/lvm/lvm.conf. But in said file on my machine, I didn't find the cited content. I double-checked man lvm.conf(5), didn't see any mentioning of this option either. Thus, I'm not sure what to do. Furthermore, even say adding the option is the right thing to do, should I in my machine's /etc/fstab still add mount options such as noatime etc? Any tips, pointers, and/or further guidance are greatly appreciated.

    I have recently distributed my WiFi network with highpseed antennas to my area which covers almost 300-400 peoples. I am not charging them anything but i would like to generate some revenue through Advertisements placed on the websites that they visit. Is it possible to display ads from Google (I know i can do redirect the Advertisements, using some cache server or firewall) . Its just like a free vpn but i would like to have my advertisements above the websites they visit so i can take out the cost for the WiFi that i offer. Any suggestions would be great!

  • How to obtain flow while pair programming in agile development?

    - by bizso09
    Flow is is concept introduced by Mihaly Csikszentmihalyi In short, it means what most to get into the "zone". You feel immeresed in the task you are doing, you are in deep focus and concentration and the task difficulty is just right for you, but challenging at the same time. When people acquire flow their prodctivity shoots up. Programming requires great deal of mental focus and programmers need to juggle several things in their mind at once. Many like to work in a quite environment where they can direct their full attention to the task. If they are interreupted, it may take several minutes, sometimes hours to get back into flow. I understand that agile way of doing software development is called pair prograaming. This is pormoted in Extreme programming too. It means you put the whole software development team in one room so that communication is seamless. You do programming with your pair because this way you get instant code reviews and fix bugs sooner. However, I alwys had problem obtaining flow while doing pair programming because of the contant stream of interrupts. I'm thinking deep about an issue then all of sudden someone asks me a question from another pair. My train of thought is all lost. How can you obtain and keep flow while doing agile pair programming?

  • how do I match movement of an object from 2d video into a 3d package ?

    - by George Profenza
    I'm trying to add objects in a 3d package(Blender) using recorded footage. I've played with Icarus and it's great to capture the camera movement. Also the Blender 2.41 importer script works in Blender 2.49 as well. The problem is I can't seem to get 3d coordinates for objects. I have tried Autodesk(RealVIZ) MatchMover 2011 and gone through the tutorials. Tutorial 3 shows how to link a vertex from a 3d mesh to a 2d trackpoint, but the setup is for camera movement. Tutorial 4 goes into Motion capture, but it uses 2 videos of the same motion taken with 2 cameras from different viewpoints. I've tried to bypass that using the same footage twice, but that failed, as the 3d coordinate system ends up messed up. What software do you recommend for this (mapping 3d coordinates to 2d tracked points and importing them into a 3d package) ? What is the recommended technique ? Any good examples out there ? Thanks, George

  • IPSEC tunnel Fortinet Transparent Mode to inside Fortinet firewall in NAT Mode does not respond to i

    - by TrevJen
    I have 2 fortinet firewalls (fully patched); fw1 is providing an IPSEC tunnel in transparent mode. beneath this firewall is a fw2, a NAT firewall with a VIP address that has been confirmed to work. This configuration is required for my customers who want to connect to a public address space inside of the tunnel, in order to prevent cross over in IP space. This configuration works great for traffic going outbound to the remote side of the tunnel, but not inbound. While sniffing the traffic, I can see the inbound traffic going out of the fw1, but it is never seen at the fw2.

  • nginx + php-fpm “504 Gateway Time-out” after compiling with curl support

    - by Brian
    We recently switched to managing php with php-fpm. It was working great, but is now giving me issues. The most recent change was to install libcurl-devel and re-compile php (5.3.3) using --with-curl. Now I'm getting 504 timeouts with nginx and the pages won't load. HTML pages load fine, phpinfo() loads as well. Tried backing out the changes and re-compiling without curl support, but still not having any luck. Also tried adjusting request_terminate_timeout per some of the other posts here on SF without change. This is on a test machine that has no other clients hitting it. I also tried switching to unix socket instead of tcp--same result. What am I missing here? Am I barking up the wrong tree with curl?

  • Yes WinRT Devices Have a Desktop&hellip;But Not For Us

    - by D'Arcy Lussier
    So tonight this convo happened: Intrigued, I viewed the video Lee mentions and found that its the now infamous Brent Ozar video which shows a bug in Word on the Surface RT (you can read this article which talks about the tempest in a teacup that ensued). But Lee is correct – in the video, when Brent starts up Word 2013, we see this: That sure does look like a desktop doesn’t it! But…aren’t Windows RT devices *not* supposed to come with a desktop? Actually, it does. However, it’s not a *full* desktop. From Seth Rosenblatt’s fantastic Windows RT FAQ article: Windows RT will have a Desktop mode, but it will be restricted to pre-installed, Microsoft-produced software. This will include touch-optimized versions of Microsoft Word, Excel, PowerPoint, and OneNote as the new Microsoft Office So yes, there’s a desktop mode in Windows RT but no, you won’t be able to install apps to it. Confused yet? Read the rest of the Seth’s FAQ – it does a great job clearing the haze of confusion that Microsoft Marketing Merlins have cast upon all of us. D

  • Going Paperless

    - by Jesse
    One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

  • Consolidate SQL Server Reporting Services

    - by Eric C. Singer
    I've been a big fan of consolidating as many DB's to a few SQL servers for a while and I've had great success with it. However, I've never had to deal with SQL reporting services. Has anyone migrated SSRS from a bunch of random SQL servers into a consolidated SQL server? I don't exactly know a whole lot about SSRS which is part of the problem. To my knowlege, it's one DB per SSRS instance, so it sounds like i'd need to find a way of exporting data and merging it. Basically the process used to look like: Move DB from SQL Express to shared SQL server Change point in APP to point at new SQL server With reporting services, how do I move the reporting service compenent of the DB as well? I realize I may need to tweak the app, but my question is on the SQL side.

  • Mac OS X: easiest (free, non-QuickTime Pro) application for converting numbered folder of images to

    - by Jared Updike
    I'd like to convert a folder of PNGs into a quicktime .mov with PNG compression (it's a folder of fractals in an animation; PNG compression works great here and the losslessness is important). What programs will do this with minimal fuss? (I don't have or want to pay for a full license of QuickTime Pro.) UPDATE: Let me make this more clear: minimal fuss means: I download some EncoderMagic.app (for example), I double click it to launch it. I select the folder with my numbered images, and out pops my movie. No mess. No resizing. ... Perhaps this doesn't exist (or is called QuickTime Pro?)

  • Using NDMP as an alternative to CIFS mount

    - by user138922
    I have a weird but interesting use-case. I use CIFS to mount shares from a File Server (NetApp, EMC etc) to an application server (win/linux server where my application runs). My application needs to process each of the file from the shares that I mount via CIFS. My application also needs access to the meta-data of these files such as Name, Size, ACLs etc. I would like to see if I can achieve the same via NDMP. I have some very basic questions regarding this use-case. It would be great if you guys can help me out here. Is this even something which is achievable? Can I just transfer share that interest me instead of entire volume?

  • How to Make Sure Your Company Doesn't Go Underwater If Your Programmers Are Hit by a Bus

    - by Graviton
    I have a few programmers under me, they are all doing very great and very smart obviously. Thank you very much. But the problem is that each and every one of them is responsible for one core area, which no one else on the team have foggiest idea on what it is. This means that if anyone of them is taken out, my company as a business is dead because they aren't replaceable. I'm thinking about bringing in new programmers to cover them, just in case they are hit by a bus, or resign or whatever. But I afraid that The old programmers might actively resist the idea of knowledge transfer, fearing that a backup might reduce their value. I don't have a system to facilitate technology transfer between different developers, so even if I ask them to do it, I've no assurance that they will do it properly. My question is, How to put it to the old programmers in such they would agree What are systems that you use, in order to facilitate this kind of "backup"? I can understand that you can do code review, but is there a simple way to conduct this? I think we are not ready for a full blown, check-in by check-in code review.

It is the foundation stone on which all other products (Exchange, update services, office communicator, the system center family, etc) rely on to get their information. And that is just looking at it from an infrastructure perspective. A well designed and implemented Active Directory implementation makes life for IT personnel and user alike a lot easier. Centralised management and the abilities opened up  by having it in place are ample.  But what is Active Directory Domain Services? We can look at ADDS as a centralised directory containing all objects your infrastructure runs on in one way or another. Since it is a Microsoft product you'll obviously not be seeing linux or mac clients listed in here (exceptions exist) but in general we can say it contains everything your company has in place in one form or another.  The domain name services. The domain naming service (or DNS for short) is a service which translates IP address (the identifiers for each computer in your domain) into readable and easy to understand names. This service is a prequisite for ADDA to work and having wrong record in a DNS server will make any ADDS service fail. Generally speaking a DNS service will be run on the same server as the ADDS service but it is worth wile to remember that this is not necessary. You could, for example, run your DNS services on a linux box (which would need special preparing to host an ADDS integrated DNS zone) and run the ADDS service of another box… Where to start? If the aim is to put in place a first time implementation of ADDS in your enterprise there are plenty of things to consider depending on what you are going to do in the long run. Great care has to be taken when first designing and implementing as having it set up wrong will cause a headache down the line. It is for that reason that I like to start building from the bottom up and start with a generic installation of ADDS (which will still differ for every client) and make it adaptable for future services which can hook in to the existing environment. Adapting existing environments is out of scope for this document (and series) although it is possible to take the pointers and change your existing environment to run in a smoother manor. Take great care when changing things as one small slip of the hand can give you a forest wide failure… Whenever starting with an ADDS deployment I ask the client the following questions:  What are your long term plans and goals?  How flexible do you want it? Are you currently linux heavy and want to keep this or can we go for an all Microsoft design? Those three questions should give some sort of indicator what direction can be taken and if the client has thought about some things themselves :).  The technical side of things  What is next to consider is what kind of infrastructure is already in place. For these series I'll keep it simple and introduce some general concepts without going in to depth on integrating ADDS with other DNS services.  Building from the ground up means we need to consider our layers on which our infrastructure will rely. In my view that goes as follows:  Network (WAN/LAN links and physical sites DNS Namespacing All in one domain or split up in different domains/forests? Security (both for ADDS and physical sites) The network side of things  Looking at how the network is currently set up can potentially teach us a large deal about the client. Do they have multiple physical site? What network speeds exist between these sites, etc… Depending on this information we will design our site links (which controls replication) in future stages. DNS Namespacing Maybe the single most intresting thing to know is what the domain will be named (ADDS will need a DNS domain with the same name) and where this will be hosted. Note that active directory can be set up with a singe name (aka contoso instead of contoso.com) but it is highly recommended to never do this. If you do end up with a domain like that for some reason there will be a lot of services that are going to give you good grief in the future (exchange being one of them). So one of the best practises would be always to use a double name (contoso.com or contoso.lan for example). Internal namespace A single namespace is just what it sounds like. You have a DNS domain which is different internally from what the client has as an external namespace. f.e. contoso.com as an external name (out on the internet) and contoso.lan on the internal network. his setup is has its advantages in that you have more obscurity from the internet in the DNS side of this but it will require additional work to publish services to the web. External namespace Quite like the internal namespace only here you do not differ the internal namespace of the company from what is known on the internet. In this implementation you would host your own DNS servers for the external domain inside the network. Or in other words, any external computer doing a DNS lookup would contact your internal DNS server for the resolution. Generally speaking this set up is a bad idea from the security side of things. Split DNS Whilst using an external namespace design is fairly easy it involves a lot of security risks. Opening up you ADDS DSN servers for lookups exposes your entire network to the internet and should be avoided at any cost. And that is where the "split DNS" design comes in. In this setup up would still have the same namespace internally and externally but you would be using different DNS servers for lookups on the external network who have no records of your internal resources unless you explicitly publish them. All in one or not? In determining your active directory design you can look at the following possibilities:  Single forest, Single domain Single forest, multiple domains Multiple forests, multiple domains I've listed the possibilities for design in increasing order of administrative magnitude. Microsoft recommends trying to use a single forest, single domain in as much situations as possible. It is, however, always possible that you require your services to be seperated from your users in a resource forest with trusts set up between the different forests. To start out I would go with the single forest design to avoid complexity unless there are strict requirements to have multiple forests. Security What kind of security is required on the domain and does this reflect the physical security on the sites? Not every client can afford to have a domain controller in a secluded server room on every site and it is exactly for that reason that Microsoft introduced the RODC (read only domain controller). A RODC is a domain controller that has been limited in functionality, in essence it will only cache the data you explicitly tell it to cache and in the case of a DC compromise (it being stolen) only a limited number of accounts will need to be affected. Th- Th- Th- That’s all folks! Well at least for now! In future editions of this series we’ll be walking through the different task that need to be done and the thought which needs to be put in to it. But for all editions we’ll be going from the concept of running a single forest, single domain with a split DNS setup… See you next time!

  • IIM Calcutta &ndash; EPBM 14 &ndash; Campus Visit &ndash; Day 4 &ndash; Managing Self, SDCC and Gari

    - by Ram Shankar Yadav
    …I’m becoming more of an addict of writing about my experiences, here in Kolkata! Today we started a bit of late at around 8 AM, did our breakfast and reached in class a bit late at around 9:50 AM, and here goes the surprise…. Today we had two lectures on “Managing Self” and two lectures on “Sustainable Development and Climate Change” (SDCC). Some of us got few self discipline lessons the moment they entered class and asked to “get out” :D So frankly speaking it was a nostalgic moment, which reminded us of Collage ;) We did a FIRO-B test as and got very good tips on managing ourselves and differentiate between “manager” and “leader” After the lunch we had our session on SDCC, in which the prof started by explaining “Credit Crisis”, and moved on to Sustainable Development and few great examples from industry and life~! After the class we went for shopping at Garihat Market, we ate Pani Puri and Moodi :P ..one more surprise…my room got flooded with lot of my new ePBM friends to take the copy of the pictures and we did lot of chit chat around anything and everything :D …so far so good…it’s an amazing experience for me and hopefully for others….who came out of their daily chores and went back to the nostalgic lanes of friendship, learning and most importantly “Happyness” ~~~ Cheers, ram :) EPBM 14 pics : http://epbm14.shutterfly.com/pictures
