• Links for Getting Started with PowerShell for Office 365 and Exchange Online

  - by Brian Jackett

  This past week I worked with some customers who were getting started with using PowerShell against Exchange Online as part of their new Office 365 solution.  As you may know Exchange is not my primary focus area but since these customers’ needs centered around PowerShell I thought this would be a good opportunity to learn more.  What soon became apparent to me was a few things: The output / objects returned from Exchange Online vs. on-premises commandlets sometimes differ (mainly due to Exchange Online output needing to be serialized across the wire) Some of the community scripts posted on TechNet Script Center or PoSH Code Repository that work for on-premises won’t work against Exchange Online due to the above I went to multiple resources to get an introduction of using the Exchange Online commandlets      In light of the last item I would like to share some resources I gathered for getting started with the Exchange Online commandlets.  I will address the first two items in a follow up post that shows one sample script that I helped a customer fix.   Links Using PowerShell with Office365 http://blah.winsmarts.com/2011-4-Using_PowerShell_with_Office365.aspx   Administering Microsoft Office 365 using WIndows PowerShell http://blog.powershell.no/2011/05/09/administering-microsoft-office-365-using-windows-powershell/   Reference to Available PowerShell Cmdlets in Exchange Online http://help.outlook.com/en-us/140/dd575549.aspx   Windows PowerShell cmdlets for Office 365 http://onlinehelp.microsoft.com/en-us/office365-enterprises/hh125002.aspx   Role Based Access Control in Exchange Online http://help.outlook.com/en-us/140/dd207274.aspx   Exchange Online and RBAC http://blogs.technet.com/b/ilvancri/archive/2011/05/16/exchange-online-office365-and-rbac.aspx   Conclusion    Office 365 is being integrated into more and more customers’ environments.  While your PowerShell skills can still be used to manage certain portions of Office 365 (Exchange Online as of the time of this writing) there are a few differences in how data is passed back and forth.  Hopefully the links above will get you started on scripting against  cloud based services.         -Frog Out

• Why does my browser take me to Scour.com? (redirect virus)

  - by Paula DiTallo

  The "scour" or Rootkit.Win32.TDSS virus has a long history which can be found here: http://en.wikipedia.org/wiki/Scour Here is the primary symptom: after searching for something in your web browser using google, one of the results that you click on redirects you to scour.com. If you've executed ClamWin, Malwarebytes, McAfee, Norton, etc. to find and isolate the virus without any luck--this isn't really a surprise, since this virus attaches to existing system drivers. I only know of one reliable package that will remove this without ill effects--like adding new spyware. This package is called TDSSKiller. I have seen multiple websites that claim to have this software available, but the one that I know is reliable is located here: http://support.kaspersky.com/viruses/solutions?qid=208280684 Once you go to Kaspersky's tech support site, the TDSSKiller zip file is available for downloading. When you execute this software, you will be able to "cure" or repair the infected driver. Remember to jot down the name of the driver for future reference--should you need to reinstall the driver from a "same-as" working computer, or your install disk if the repair is ineffective. The driver that happened to get infected on my computer was the tcpip.sys driver. This caused my win sockets to loose their ip addresses. In most other instances, less critical drivers such as HDAudBus.sys are infected. In my case, I was not through correcting my computer problems until I corrected the broken WinSock issue and loaded an earlier version of the tcpip.sys driver from: C:\WINDOWS\ServicePackFiles\i386 which I placed in: C:\WINDOWS\system32\drivers Don't forget to reboot your computer after your repair! Once you download TDSSKiller and cure/repair your infected driver(s), the redirect on google searches should disappear .

• Message Queue: Which one is the best scenario?

  - by pandaforme

  I write a web crawler. The crawler has 2 steps: get a html page then parse the page I want to use message queue to improve performance and throughput. I think 2 scenarios: scenario 1: structure: urlProducer -> queue1 -> urlConsumer -> queue2 -> parserConsumer urlProducer: get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and add it to queue2 parserConsumer: according to the job info, parse the page scenario 2: structure: urlProducer -> queue1 -> urlConsumer parserProducer-> queue2 -> parserConsumer urlProducer : get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and write it to db parserProducer: get the html page from db and add it to queue2 parserConsumer: according to the job info, parse the page There are multiple producers or consumers in each structure. scenario1 likes a chaining call. It's difficult to find the point of problem, when occurring errors. scenario2 decouples queue1 and queue2. It's easy to find the point of problem, when occurring errors. I'm not sure the notion is correct. Which one is the best scenario? Or other scenarios? Thanks~

• What is a Data Warehouse?

  Typically Data Warehouses are considered to be non-volatile in comparison to traditional databasesdue to the fact that data within the warehouse does not change that often.  In addition, Data Warehouses typically represent data through the use of Multidimensional Conceptual Views that allow data to be extracted based on the view and the current position within the view. Common Data Warehouse Traits Relatively Non-volatile Data Supports Data Extraction and Analysis Optimized for Data Retrieval and Analysis Multidimensional Views of Data Flexible Reporting Multi User Support Generic Dimensionality Transparent Accessible Unlimited Dimensions of Data Unlimited Aggregation levels of Data Normally, Data Warehouses are much larger then there traditional database counterparts due to the fact that they store the basis data along with derived data via Multidimensional Conceptual Views. As companies store larger and larger amounts of data, they will need a way to effectively and accurately extract analysis information that can be used to aide in formulating current and future business decisions. This process can be done currently through data mining within a Data Warehouse. Data Warehouses provide access to data derived through complex analysis, knowledge discovery and decision making. Secondly, they support the demands for high performance in regards to analyzing an organization’s existing and current data. Data Warehouses provide support for an organization’s data and acquired business knowledge.  Within a Data Warehouse multiple types of operations/sub systems are supported. Common Data Warehouse Sub Systems Online Analytical Processing (OLAP) Decision –Support Systems (DSS) Online Transaction Processing (OLTP)

• Design pattern for client/server sessions?

  - by nonot1

  Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.

• Getting MSExchange transport Error on Server 2003 SP2

  - by Scott

  I am getting the following Error messages and do not know how to fix it. Event Type: Error Event Source: MSExchangeTransport Event Category: (8) Event ID: 3017 Date: 4/29/2010 Time: 1:21:12 PM User: N/A Computer: NETSRV Description: A non-delivery report with a status code of 5.3.5 was generated for recipient rfc822;[email protected] (Message-ID <19104335.51321272561635734.JavaMail.SYSTEM@PARROT).

• Help with Rewrite rules.

  - by Kyle

  I was wondering what a rewrite statement that looks for this situation. I want to have multiple users on my server. Each user can have 'VirtualDocumentRoot' like sites in his directory. For example, they just make a directory like 'example.com' in their home directory, and it's hosted. The problem is I don't know if VirtualDocumentRoot can do this, or if it would take a rewrite rule that looks in all the users folders for a domain. Can anybody help me?

• How do I choose the scaling factor of a 3D game world?

  - by concept3d

  I am making a 3D tank game prototype with some physics simulation, am using C++. One of the decisions I need to make is the scale of the game world in relation to reality. For example, I could consider 1 in-game unit of measurement to correspond to 1 meter in reality. This feels intuitive, but I feel like I might be missing something. I can think of the following as potential problems: 3D modelling program compatibility. (?) Numerical accuracy. (Does this matter?) Especially at large scales, how games like Battlefield have huge maps: How don't they lose numerical accuracy if they use 1:1 mapping with real world scale, since floating point representation tend to lose more precision with larger numbers (e.g. with ray casting, physics simulation)? Gameplay. I don't want the movement of units to feel slow or fast while using almost real world values like -9.8 m/s^2 for gravity. (This might be subjective.) Is it ok to scale up/down imported assets or it's best fit with a world with its original scale? Rendering performance. Are large meshes with the same vertex count slower to render? I'm wondering if I should split this into multiple questions...

• Recommended website performance monitoring services? [closed]

  - by Dennis G.

  I'm looking for a good performance monitoring service for websites. I know about some of the available general monitoring services that check for uptime and notify you about unavailable services. But I'm specifically looking for a service with an emphasis on performance. I.e., I would like to see reports with detailed performance statistics from multiple locations world-wide, with a break-down on how long it took to fetch the different website resources, including third-party scripts such as Google Analytics and so on (the report should contain similar details such as the FireBug Net tab). Are there any such services and if so, which one is the best?

• How do I prevent missing network from slowing down boot-up?

• One bigger Virtual Machine distributed across many OpenStack nodes [duplicate]

  - by flyer

  This question already has an answer here: Can a virtualized machine have the CPU and RAM resources of multiple underlying physical machines? 2 answers I just setup virtual machines on one hardware with Vagrant. I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM with OS | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- More details: In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes. If we imagine this Nodes(Novas) are placed on a separate machines (e.g. every has 4 cores) can I run one Virtual Machine across many OpenStack Nodes? Is it possible to aggregate the computation power of OpenStack in one virtual distributed operating system?

• How to switch users without entering password

  - by torbengb

  I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

• What is a technique for 2D ray-box intersection that is suitable for old console hardware?

  - by DJCouchyCouch

  I'm working on a Sega Genesis homebrew game (it has a 7mhz 68000 CPU). I'm looking for a way to find the intersection between a particle sprite and a background tile. Particles are represented as a point with a movement vector. Background tiles are 8 x 8 pixels, with an (X,Y) position that is always located at a multiple of 8. So, really, I need to find the intersection point for a ray-box collision; I need to find out where along the edge of the tile the ray/particle hits. I have these two hard constraints: I'm working with pixel locations (integers). Floating point is too expensive. It doesn't have to be super exact, just close enough. Multiplications, divisions, dot products, et cetera, are incredibly expensive and are to be avoided. So I'm looking for an efficient algorithm that would fit those constraints. Any ideas? I'm writing it in C, so that would work, but assembly should be good as well.

• Video for an ads-driven web-site

  - by AntonAL

  I have a website, wich i will fill with a bunch of useful videos. I've implemented an ads rotation engine for articles and will do so for videos. The next milestone is to decide, how video will be integrated. They are two ways: To host videos myself. Pros: complete freedom. Cons: need tens of gigabytes of storage; support for multiple formats to be crossbrowser and crossdevice. Use Youtube. Pros: Very simple to use; nothing to do. What are pros and cons for each way ? Some questions for YouTube: Will i be able to control playback of YouTube-embedded video to make post-rolls ? What is ranking impact on my web-site, when most of pages will refer to YouTube ? Will, say, iPad play video, embedded via YouTube's iframe ? Does relying entirely on YouTube have a long-term perspective for a web-site, that should bring money ?

• Software for video subscription service

  - by Clinton Blackmore

  I'd like to sell instructional videos over the web. Primarily, I'd like uses to subscribe to the site and be allowed access to videos over the internet. Secondarily, I might sell DVDs for those who have poor internet connections or would like a physical copy, or possibly I'd sell eBooks and the like in the future. Regarding the subscriptions: I'd like a system that automatically sends out e-mails when it is time to renew I'd like to be able to offer free trials Users without a free trial or subscription should not be able to access the content Incidentally, I plan to host videos on my current web host and move them to a CDN when volume (and capital) make this a good idea. While I have no intention to go crazy with the DRM, it seems expedient not to directly link to the files -- how can I link to them indirectly? It would be nice to support multiple payment processors -- specifically, I'd like to avoid a PayPal only approach. Are there any web applications (or plugins) you'd recommend for something like this? While I've set up and administered several web technologies, I've never done anything with e-commerce. I see there are possibilities like osCommerce, one friend recommends using WordPress with plugins, and it really appears that for any given CMS, you can graft on components like this, although I imagine that not all are created equal. As I'm not tied to a particular web application (and, while open source software that can run on a LAMP [p=perl, python, php] stack is preferable), I'd like to make a good choice at the beginning.

• Management Reporter Installation – Lessons Learned

  - by Ryan McBee

  After successfully completing several installations of Management Reporter this year, I wanted to share a few lessons learned that should help you. First, you will want to make sure that you install Management Reporter under a domain account as opposed to a local system or network service account. Management Reporter gives you the option to install under these accounts, but it is a be a best practice approach to use a domain account. Upon installation of Management Report, you will want to make sure that Directory Browsing is enabled within the IIS server of your site or you will have problems when you go to use Management Reporter. By default, it will be disabled in Server 2008 R2 and you will need to make the setting change under the Actions pane shown below. Lastly, you will want to make sure that SQL Server is running under a domain account. I have had multiple situations where reports have been stuck in the Queued status rather than Processing status of Management Reporter. After reviewing resolution 5 of KB 2298248, it was determined that running SQL Server under a domain account is the way to go.

• How to change CapsLock key to produce "a"?

  - by Pit

  While typing I often hit the CapsLock key instead of the a key. (QWERTZU keyboard) This is quite annoying because the moment I realise that I hit the wrong key, I will have to delete multiple character/lines of text an rewrite them in the right form. I am searching for a way to prevent this. I have found a possibility to disable the CapsLock key in Keyboard Layout Options. But this would in my case mean that instead of writing an a I would write nothing. Positive - I don't have to rewrite a whole line, but only one character Negative - It's not that obvious that I hit the wrong key, as a missing character is not perceivable as an upper-case line of text. I would therefore prefer a possibility to map CapsLock to a . Thus when hitting CapsLock an a character would be written. Positive - If I hit CapsLock instead of a I get the output I actually wanted to type. Negative - If I hit CapsLock in any other context I will get an a character. As I don't ever intentionally use the CapsLock key this would not really pose a problem. (I think, or does it?) My Question: So how do I change to a ? And is there any case where this could be dangerous/provoke unwanted behaviour?

• Ubuntu Server Read-Only Filesystem Issue

  - by Scott Deutsch

  We are running a virtual machine server with multiple virtual machines with ubuntu server edition 12.04 and every so often (usually after updates via webmin it seems), the hard-drive turns into read-only filesystem. Only two of the virtual machines get affected by this problem (that I noticed so far). What could be causing this issue? What could we try to fix this problem? Has anyone else had this problem before? If so, what did you do to fix it? If I use Aptitude instead of webmin, it will not turn into into a read-only filesystem. Though this could be a coincidence. Could it be a webmin issue? Thanks. UPDATE 1 Looks like this is not an update/webmin issue at all. How I know this is because one of the virtual servers is a git server and it turned into a read-only filesystem out of the blue today. With this new info provided to you, what should I try? Thanks.

• Problems with Adobe Flash

  - by Georg Scholz

  I'm running Windows 7, 64-Bit on a Core-i5 HP Notebook. For approximately the last 3 months, I've had major problems with Adobe Flash. Flash has been uninstalled and installed again multiple times. No changes. Here is what happens in different browsers: (All browsers are in the latest version as of this post) Firefox: Doesn't work at all. This bothers me most, since FF is my favorite browser; I'm using a lot of Plugins. Have tried to de-activate all Plugins, but no change. IE and Chrome: Works, but most pages with Flash are stuck during page load for ~30 seconds. After that, everything is fine. Opera: No problems, everything working as it should. Strange, eh? Any help is highly appreciated!

• The Oldest Big Data Problem: Parsing Human Language

  - by dan.mcclary

  There's a new whitepaper up on Oracle Technology Network which details the use of Digital Reasoning Systems' Synthesys software on Oracle Big Data Appliance.  Digital Reasoning's approach is inherently "big data friendly," as it leverages multiple components of the Hadoop ecosystem.  Moreover, the paper addresses the oldest big data problem of them all: extracting knowledge from human text.   You can find the paper here.   From the Executive Summary: There is a wealth of information to be extracted from natural language, but that extraction is challenging. The volume of human language we generate constitutes a natural Big Data problem, while its complexity and nuance requires a particular expertise to model and mine. In this paper we illustrate the impressive combination of Oracle Big Data Appliance and Digital Reasoning Synthesys software. The combination of Synthesys and Big Data Appliance makes it possible to analyze tens of millions of documents in a matter of hours. Moreover, this powerful combination achieves four times greater throughput than conducting the equivalent analysis on a much larger cloud-deployed Hadoop cluster.

• How to learn the math behind the code?

  - by Solomon Wise

  I am a 12 year old who has recently gotten into programming. (Although I know that the number of books you have read does not determine your programming competency or ability, just to paint a "map" of where I am in terms of the content I know...) I've finished the books: Python 3 For Absolute Beginners Pro Python Python Standard Library by Example Beautiful Code Agile Web Development With Rails and am about halfway into Programming Ruby. I have written many small programs (One that finds which files have been updated and deleted in a directory, one that compares multiple players' fantasy baseball value, and some text based games, and many more). Obviously, as I'm not some sort of child prodigy, I can't take a formal Computer Science course until high school. I really want to learn computer science to increase my knowledge about the code, and the how the code runs. I've really become interested in the math part after reading the source code for Python's random module. Is there a place where I can learn CS, or programming math online for free, at a level that would be at least partially understandable to a person my age?

• Does ssh key need to be named id_rsa?

  - by dustyprogrammer

  I have come across this problem a couple of times when creating build servers with keyed authentication. I was wondering if anyone else has experience this. I have a couple of keys for my current user that may connect to different machines. Let say machine1 and machine2. I have pasted my public key into their respective authorized_keys file. The first one I have named the first key id_rsa and the second key bender. When I try to connect to bender I get the following output with my verbose ssh connection debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/bozo/.ssh/.ssh/identity debug1: Trying private key: /home/bozo/.ssh/.ssh/id_rsa debug1: Trying private key: /home/bozo/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). It only offers the id_rsa key, as you can see above. Is this correct? If so why? How do I get it to offer more keys? I know it is a problem I see intermittently, because I at home I have multiple keys without much trouble. I would also appreciate a overview on how the pub and private keys interact with the client and server. I thought I had a pretty decent idea, but apparently I am missing something. Please and thank you.
