• SharePoint 2010 MySites - Simple explanation needed!

  - by Chris W

  I've been playing around with the 2010 beta for a couple of weeks, experimenting with topology options etc. I think I've got myself totally confused as to how it works hence if there's any SP experts out there that can explain things in simple terms for me I'd appreciate it! I want to setup a farm with 3 servers providing the content & MySites. I presume that the way to do this is to load balance or DNS round robin traffic between the 3 servers. The bit where I'm confused is that My Site Settings page asks for a specific My Site Host hence all my site traffic will be pushed to a single server even though we have 3 in the farm. If this hosts fails I presume MySites will be unavailable. Is this right? How do I configure it so that access to MySites is load balanced across the 3 servers in the farm?

• Which iPhone ad API has produced the highest revenue for you?

  - by Kyle Humfeld

  This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

• Is there a schematic overview of Ubuntu's architecture?

  - by joebuntu

  Hi there, as enthusiastic, advanced Linux learner, I'd love to get an overview about Linux' architecure/structure in general. You know, like "the big picture". I'm thinking of a large schematic graphic showing what is what, who is who, what system (e.g. X) comprises which subsystems (GDM/Gnome/Compiz) on the way from a to z, from boot to interactive desktop, including the most important background services (auth, network, cron, ...). Maybe a bit like this: http://www.flickr.com/photos/pgc/140859386/ but way more detailed. There's bootchart, which produces very comprehensive charts, but they again are too detailed and difficult to get the "big picture" from. Is there such a thing? Possibly not for the whole System, but maybe for single subsystems? I had trouble searching for this, because using search terms like "scheme" or "architecture" pointed to the wrong direction (a tool called "scheme" or CAD software for linux). I appreciate any links. If there's interest in those schematic overviews and links, maybe someone could turn this post into a wiki post? Cheers, joebuntu

• How can I deal with a difficult developer that is holding back the project? [migrated]

  - by ILovePaperTowels

  Our entire project is being held up because of one piece which is being handled by a single developer. When we did finally got the latest version of his code and started reviewing it, we found the code was horrendous! Its a relatively simply workflow, however the code is so complex that it's very difficult to step through and review/debug. The developer responsible has a hard time accepting any kind of criticism, and feels he is more knowledgeable than others members of the team. It's difficult to even talk to him about his development work because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but management is not doing anything. This is probably because devs are in short supply where we are, and this is a corporation has a lot of office drama. I'm just one of the developers, not the project manager, however I really want to see this project succeed. What can I do in this sort of situation to try and keep the project on track?

• Business Forces: SOA Adoption

  The only constant in today’s business environment is change. Businesses that continuously foresee change and adapt quickly will gain market share and increased growth. In our ever growing global business environment change is driven by data in regards to collecting, maintaining, verifying and distributing data.  Companies today are made and broken over data. Would anyone still use Google if they did not have one of the most accurate search indexes on the internet? No, because their value is in their data and the quality of their data. Due to the increasing focus on data, companies have been adopting new methodologies for gaining more control over their data while attempting to reduce the costs of maintaining it. In addition, companies are also trying to reduce the time it takes to analyze data in regards to various market forces to foresee changes prior to them actually occurring.   Benefits of Adopting SOA Services can be maintained separately from other services and applications so that a change in one service will only affect itself and client services or applications. The advent of services allows for system functionality to be distributed across a network or multiple networks. The costs associated with maintain business functionality is much higher in standard application development over SOA due to the fact that one Services can be maintained and shared to other applications instead of multiple instances of business functionality being duplicated via hard coding in to several applications. When multiple applications use a single service for a specific business function then the all of the data being processed will be consistent in terms of quality and accuracy through the applications. Disadvantages of Adopting SOA Increased initial costs and timelines are associated with SOA due to the fact that services need to be created as well as applications need to be modified to call the services In order for an SOA project to be successful the project must obtain company and management support in order to gain the proper exposure, funding, and attention. If SOA is new to a company they must also support the proper training in order for the project to be designed, and implemented correctly. References: Tews, R. (2007).

• IIS not using available memory?

  - by Herb Caudill

  Recently launched an ASP.NET site running on a single 32-bit WS2003 box (SQL on a separate server). The server has 4GB intalled, 3GB available. According to task manager, the w3wp.exe process is only using between 200-600MB. The site has tens of thousands of pages and makes heavy use of page output caching, so I would expect it to use a lot more of the available memory. The app pool isn't set to throttle memory usage. Is there anything else that might be limiting the amount of memory that IIS takes?

• Updating wordpress in a multi-node environment

  - by Peter

  I'm finding this very tricky in a multi node environment, with code under revision control. AKA. multiple frontends and single database. I have a deployment process that pushes a git repo to the servers, but obviously if I update Wordpress from within the admin panel, it will update the files to one FE. Then I would need to copy over the new files to the other FE nodes. Plus, whenever these changes are written when Wordpress updates on a node, it writes code into the git repo. As such, it then breaks the auto deploys that perform 'git pulls', as it then has untracked changes and refuses to pull in new deploys unless manually intervened. How does one easily keep Wordpress updated in a multi node (load balanced) environment?

• Joining H264 *without* re-encoding

  - by jdmuys

  I have two halves of a single show in two .MP4 files, encoded in H264. I would like to join them without re-encoding. Is this possible? I managed to create a joined video as a Quicktime file (.mov) using Quicktime Pro, but then Quicktime Pro will not convert it back to .MP4 without re-encoding. This may be because looking inside the .mov file, the two H264 videos are in there still separated as individual "objects". I am also struggling with MPEG StreamClip without reaching a real solution. But I may have missed something. Note that I do not have the same issue with MPEG2 files. I can export them to a .MPEG container or a .TS file for example, and then I can join them without re-encoding using MPEG Streamclip. Any suggestion welcome, preferably using Mac software.

• How do I change the canvas size of a PNG with ImageMagick (GraphicsMagick)? (How to pad with transparency?)

  - by Pistos

  Alternatively: How do I take a non-square PNG and "fill out" the "rest" of the image with transparency so that the resulting square image has the original image centered in the square? ULTIMATELY, what I want is to take any image of any GM-supported format of any size, and create a scaled-down PNG (say, 40 pixels maximum for either dimension), with aspect ratio maintained, transparency-padded for non-square original images, AND with an already-prepared 40x40 PNG transparency mask applied. I already know how to scale down and keep aspect ratio; I already have the command for applying my composite. My only missing piece is square-alizing non-square images (padding with transparency). Single command preferred; multi-command chain acceptable. (edit) Extra info: Here's the composite command I'm using: gm composite -compose copyopacity mask.png source-and-target.png source-and-target.png where mask.png has white pixels for what I want to keep of source-and-target.png and transparent pixels for what I want to remove (and become transparent) of source-and-target.png.

• How to execute a command on multiple hosts using IPv6 only?

  - by math

  First of all there is pdsh which is essentially a parallel distributed shell which may execute commands on a list of given hosts. However, I find myself in an IPv6 only problem setting. It seems that pdsh is not able to use IPv6, as I am getting error messages: pdsh -w ^hostnames my_command pdsh@myhost: gethostbyname("foobar") failed I also tried to use IPv6 addresses only, which also didn't work. So how do you run a single shell script for administrative purpose (no SGE stuff, or similar) on a bunch of hosts that is IPv6 reachable only?

• Combine OS partion with data partition on NAS4Free/FreeNAS

  - by Pak

  I recently built a NAS4Free (formerly FreeNAS) machine using a 256MB (yes, MB) USB drive for the OS. When I did the original install, I had the bright idea of making the OS partition just big enough for the OS and a then creating a second partition using the remainder of the drive to store stuff pertaining to the OS. I never really found a use for the data partition and I ended up running out of space on the OS partition, so now I'd like to combine the partitions into a single partition. Is this something that is possible to do while everything is up and running? If it comes down to it, I can take down the machine and do a fresh install of the OS using the entire space of the USB drive, but I'd like to use this as an opportunity to better familiarize myself with FreeBSD/UNIX type systems. If this is possible, will it interfere with the NAS4Free things? The data partition shows up in the web interface under the disks section. If I end up manually changing the partitions, I'd be concerned with NAS4Free getting confused by the missing partition.

• Managing PHP processes on Windows 7 (with WAMP)

  - by Andrea

  Is there a way to manage (especially list and kill) long-running PHP processes on a Windows 7 system set up with WAMP? Every once in a while, I'll accidentally throw an infinite loop into a PHP process and want to kill it. Right now, all I can think to do is to restart all my WAMP services but sometimes the PHP processes manage to survive right through the restart, i.e., I still see them outputting to logs even after WAMP's restarted. And if the process isn't logging, then I have no way at all to know when/if it's been killed. Not to mention, this will wipe out everything I'm doing with WAMP, not just a single process. I don't seem to see anything relevant in the Windows Task Manager, but maybe I'm missing something.

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• Why are my downloads up to ~1500KByte/sec only, when the ADSL connection locks at 13611Kbit/s?

  - by leladax

  No uploading is going on other than the overhead of downloading which appears to be not high for the abilities of the connection: Only about 30-40KByte/s when the router locks at 1012Kb/s and other direct uploads or uploading overheads can reach more than 100KByte/sec so I don't think it's a congestion at uploading that is doing it. Is there something I miss? Because I assume 13611Kbit/s should be ~1701Kbyte/sec. Is it an overheard at the ADSL level I don't understand? Could it be the ISP doing it? If it's active throttling it can't be on single connections since 2 high speed connections still go up to ~1500KByte/sec. It's not an example on torrents or other complex situations. The tests were on Ethernet, but I doubt the results would be different on wireless. I wonder if the settings of those connections at my end could be doing it, e.g. MTU settings, though I haven't touched the defaults of a common Realtek NIC.

• Kill xserver from command line (init 3/5 does not work)

  - by Richard Martinez

  I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

• Using a random string to authenticate HMAC?

  - by mrwooster

  I am designing a simple webservice and want to use HMAC for authentication to the service. For the purpose of this question we have: a web service at example.com a secret key shared between a user and the server [K] a consumer ID which is known to the user and the server (but is not necessarily secret) [D] a message which we wish to send to the server [M] The standard HMAC implementation would involve using the secret key [K] and the message [M] to create the hash [H], but I am running into issues with this. The message [M] can be quite long and tends to be read from a file. I have found its very difficult to produce a correct hash consistently across multiple operating systems and programming languages because of hidden characters which make it into various file formats. This is of course bad implementation on the client side (100%), but I would like this webservice to be easily accessible and not have trouble with different file formats. I was thinking of an alternative, which would allow the use a short (5-10 char) random string [R] rather than the message for autentication, e.g. H = HMAC(K,R) The user then passes the random string to the server and the server checks the HMAC server side (using random string + shared secret). As far as I can see, this produces the following issues: There is no message integrity - this is ok message integrity is not important for this service A user could re-use the hash with a different message - I can see 2 ways around this Combine the random string with a timestamp so the hash is only valid for a set period of time Only allow each random string to be used once Since the client is in control of the random string, it is easier to look for collisions I should point out that the principle reason for authentication is to implement rate limiting on the API service. There is zero need for message integrity, and its not a big deal if someone can forge a single request (but it is if they can forge a very large number very quickly). I know that the correct answer is to make sure the message [M] is the same on all platforms/languages before hashing it. But, taking that out of the equation, is the above proposal an acceptable 2nd best?

• Upgrade no raid server to raid

  - by AZee

  I have just learned that our PDC has a single drive with 2 partitions. I also know that this drive has bad blocks as recorded in the event log. What I would like to do is to convert this to a RAID solution with a nice balance between economy and performance. I will admit that I have only configured servers with RAID from scratch, and have no experience upgrading an existing system into a RAID system. In fact, I'm not sure it is even possible. Since this is the PDC for 350+ workstations downtime is important. I'd like to hear from other System Administators how they would tackle this and their recommendations for all devices. At this time it seems to me that I can replace the existing drive and then restore from backup or install a controller, drives, configure the RAID an basically start from scratch. Thank you for taking your time. ~AZee

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• Extract Certs from Apache

  - by user271619

  Recently I've had to uninstall a single Self-Signed SSL Certificate from one of my Apache boxes, specifically for an outside party. That's not really a problem for me, since it was easy. What confuses me is how they knew I had a self-signed certificate. The domain I provided them was not related to the domain with the self-signed certificate. Does this mean Apache publicizes the Virtual hosts in the httpd.conf file? I asked the outside party what software they used to extract information from my server, and they provided this GitHub link: https://gist.github.com/4ndrej/4547029 I figured I'd ask the community first, before I attempt installing the Java program.

• Starting VMs with an executable with as low overhead as possible

  - by Robert Koritnik

  Is there a solution to create a virtual machine and start it by having an executable file, that will start the machine? If possible to start as quickly as possible. Strange situation? Not at all. Read on... Real life scenario Since we can't have domain controller on a non-server OS it would be nice to have domain controller in an as thin as possible machine (possibly Samba or similar because we'd like to make it startup as quickly as possible - in a matter of a few seconds) packed in a single executable. We could then configure our non-server OS to run the executable when it starts and before user logs in. This would make it possible to login into a domain.

• Is the Entity Component System architecture object oriented by definition?

  - by tieTYT

  Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

• How do I know if my Xeon Processor supports hardware virtualisation?

  - by gshankar

  I've been scouring the net (mainly the wikipaedia lists and intel's site. I even pulled out the datasheet for my processor) but I can't seem to answer this question. Does my Xeon support hardware virtualisation? The processor in question is a: "Nocona" (standard-voltage, 90 nm) 2800MHz. Other details can be found here: http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Nocona.22_.28standard-voltage.2C_90_nm.29 I'm pretty sure the answer is no as it's a pretty old server but I can't find a single place which has a definitive yes/no answer so I'm still looking...

• In an online questionnaire, what is a best way to design a database for keeping track of users all attempts?

  - by user1990525

  We have a web app where users can take online exams. Exam admin will create a questionnaire. A questionnaire can have many Questions. Each question is a multiple choice question (MCQ). Lets say an admin creates a questionnaire with 10 questions. Users attempt those questions. Now, unlike real exams users can attempt single questionnaire multiple times. And we have to keep track of his all attempts. e.g. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 1 June 2013 1 1 1 2 b 1 June 2013 1 1 1 1 c 2 June 2013 2 1 1 2 d 2 June 2013 2 Now it can also happen that after user has attempted same questionnare twice, admin can delete a question from same questionnaire, but users attempt history should still have reference to that so that user can see his that question in his attempt history in spite of admin deleting that question. If user now attempts this changed questionnaire he should see only 1 question. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 3 June 2013 3 Also, after this user modified some part of question, users attempt history should show question before modification while any new attempt should show modified question. How do we manage this at the database level? My first gut feeling was that, For deletes, do not do physical delete, just make a question inactive so that history can still keep track of users attempt. For modifications, create versions for questions and each new attempt refres to latest version of each question and history keeping reference to version of question at attempt time.

• How far do I take Composition?

  - by whiterook6

  (Although I'm sure this is a common problem I really don't know what to search for. Composition is the only thing I could come up with.) I've read over and over that multiple inheritance and subclassing is really, really bad, especially for game entities. If I have three types of motions, five types of guns, and three types of armoring, I don't want to have to make 45 different classes to get all the possible combinations; I'm going to add a motion behavior, gun behavior, and armor behavior to a single generic object. That makes sense. But how far do I take this? I can have as many different types of behaviors as I can imagine: DamageBehavior, MotionBehavior, TargetableBehavior, etc. If I add a new class of behaviors then I need to update all the other classes that use them. But what happens when I have functionality that doesn't really fit into one class of behaviors? For example, my armor needs to be damageable but also updateable. And should I be able to have use more than one type of behavior on an entity at a time, such as two motion behaviors? Can anyone offer any wisdom or point me in the direction of some useful articles? Thanks!

• Set 802.1Q tagged port on VLAN1 on Dell PowerConnect switch

  - by Javier

  I'm having big troubles when adding this Dell switch to my network. Here we use several VLANs to segment traffic. All switches (3com and DLink mostly) have configured the same VLANs, most ports are 'untagged' and belong to a single VLAN, except for the ports used to join together the switches (in a star topology), these ports belong to all VLANs and use 802.1Q tags. So far, it works really well. But on this new switch (a Dell PowerConnect 5448), the settings are very different (and confusing). I have configured the same VLANs, an the uplink ports are set in 'general' mode (supposed to be fully 802.1Q compliant), I can set the VLAN membership as 'T' on these ports for all VLANs except VLAN 1. It always stay as 'U' on VLAN 1. Any ideas?
