• SQLAuthority News – 5 days of SQL Server Reporting Service (SSRS) Summary

  - by Pinal Dave

  Earlier this week, I wrote five days series on SQL Server Reporting Service. The series is based on the book Beginning SSRS by Kathi Kellenberger. Supporting files are available with a free download from thewww.Joes2Pros.com web site. I just completed reading the book – it is a fantastic book and I am loving every bit of it. I new SSRS and I also knew how it is working however, I did not know was fine details of how I can get maximum out of the SSRS subject. This book has personally enabled me with the knowledge that I was missing in my knowledge back. Here is the question back to you – how many of you are working with SSRS and when you have a question you are left with no help online. There are not enough blogs or books available on this subject. The way Kathi has written this book is that it attempts to solve your day to day problem and make you think how you can take your daily problem and take it to the next level. Here is the article series which I have written on this subject and available to read: SQL SERVER – What is SSRS and Why SSRS is asked for in many Job Opening? Determine if SSRS 2012 is Installed on your SQL Server Installing SQL Server Data Tools and SSRS Create a Very First Report with the Report Wizard How to an Add Identity Column to Table in SQL Server Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL Tagged: Reporting Service, SSRS

• Generating Normal map from a Image with a given Albedo map

  - by snape

  I am working on a research problem part of which involves generating normal map from a given image of a rusted object. I searched the internet for techniques to achieve the above and apparently crazybump is mentioned a lot. I tried it but it didn't produce the desirable effects. Also I am looking for a method which draws inspiration from an existing research paper not some closed source software. I turned my attention to the technique described in the this paper. Results from this technique are satisfactory for normal objects because of bias in the training data but it doesn't work very well in the case of rusted objects. After this I focussed my attention on generating Albedo map (the above problem would become more solvable if Albedo map is obtained). Fortunately I am able to generate pretty good albedo maps for images of rusted objects. I used this paper's approach to generate Albedo maps. Now I want to know a good technique to get Normal map given an image and it's corresponding Albedo map. To give you an idea of what kind of images I am working with I am attaching a sample. Links to research material would be really appreciated. Thanks!

• Debugging .NET 2.0 assembly from unmanaged code in VS2010?

  - by Rick Strahl

  I’ve run into a serious snag trying to debug a .NET 2.0 assembly that is called from unmanaged code in Visual Studio 2010. I maintain a host of components that using COM interop and custom .NET runtime hosting and ever since installing Visual Studio 2010 I’ve been utterly blocked by VS 2010’s inability to apparently debug .NET 2.0 assemblies when launching through unmanaged code. Here’s what I’m actually doing (simplified scenario to demonstrate): I have a .NET 2.0 assembly that is compiled for COM Interop Compile project with .NET 2.0 target and register for COM Interop Set a breakpoint in the .NET component in one of the class methods Instantiate the .NET component via COM interop and call method The result is that the COM call works fine but the debugger never triggers on the breakpoint. If I now take that same assembly and target it at .NET 4.0 without any other changes everything works as expected – the breakpoint set in the assembly project triggers just fine. The easy answer to this problem seems to be “Just switch to .NET 4.0” but unfortunately the application and the way the runtime is actually hosted has a few complications. Specifically the runtime hosting uses .NET 2.0 hosting and apparently the only reliable way to host the .NET 4.0 runtime is to use the new hosting APIs that are provided only with .NET 4.0 (which all by itself is lame, lame, lame as once again the promise of backwards compatibility is broken once again by .NET). So for the moment I need to continue using the .NET 2.0 hosting APIs due to application requirements. I’ve been searching high and low and experimenting back and forth, posted a few questions on the MSDN forums but haven’t gotten any hints on what might be causing the apparent failure of Visual Studio 2010 to debug my .NET 2.0 assembly properly when called from un-managed code. Incidentally debugging .NET 2.0 targeted assemblies works fine when running with a managed startup application – it seems the issue is specific to the unmanaged code starting up. My particular issue is with custom runtime hosting which at first I thought was the problem. But the same issue manifests when using COM Interop against a .NET 2.0 assembly, so the hosting is probably not the issue. Curious if anybody has any ideas on what could be causing the lack of debugging in this scenario?© Rick Strahl, West Wind Technologies, 2005-2010

• How do I solve VirtualBox error 0x80004005?

  - by maria

  Hi I was trying to run Windows XP under Virtual Box (host system Ubuntu 10.04) and I've got an error message saying: Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. This is terminal output: maria@maria-laptop:~$ sudo /etc/init.d/vboxdrv setup * Stopping VirtualBox kernel modules * done. * Uninstalling old VirtualBox DKMS kernel modules * done. * Trying to register the VirtualBox kernel modules using DKMS * Failed, trying without DKMS * Recompiling VirtualBox kernel modules * done. * Starting VirtualBox kernel modules * done. After that I can run XP on Virtual Box, but when I try to log into user's account, I have the message that I have to register XP (I haven't done it yet, as each time I was cliking on pop-up window suggesting registration, nothing was happening). I click that I want to register it now and appears the message about error 0x80004005, which prevents Windows to check the license for that computer (the message is in Polish, so I don't post it here...). I forgot to install DKMS first, but I've done it after. What should I do to run virtual machine? It was using it already, the problem occured only today. Thanks for any suggestion

• Integrating different branches from external sources into a single Mercurial repository

  - by dukeofgaming

  I'm currently working in a company using Perforce and am making way for distributed version control with Mercurial. I've had success importing Perforce history using the perfarce (quite a suitable name, I laugh every time I see/say it) however, this only works with a single branch at a time. Here's how my P4 integration setup works: In perforce, create a "client", which is kind of a description of what you will be constantly updating/checking-out. This can only address one branch at a time (trunk or other). Once you do this, run hg clone p4://<server>/<client_name> Go to .hg/hgrc and put the perforce path line: perforce = p4://<server>/<client_name> Work normally with the code under mercurial, do hg pull perforce to sync up, hg push to export a changelist What I'd like to be able to do is have a perforce path per branch and have everything work in the same repository. Now, pushing is not a problem, however, if I pull the history from another branch it would end up at the default branch. I'd like to be able to do something like hg pull perforce-R5 and have it land in mercurial's R5 branch. Even if I have no merging history, it would be sweet enough to be able to preserve it. There are also other plugins for CVCSs that let you integrate mercurial, but AFAIK the subversion one has the same problem. I don't think there is a straight-through way of doing this, but as long as I could automate the process with some hooks and scripts in a single Mercurial machine, that would be good enough.

• Project Euler 14: (Iron)Python

  - by Ben Griswold

  In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 14.  As always, any feedback is welcome. # Euler 14 # http://projecteuler.net/index.php?section=problems&id=14 # The following iterative sequence is defined for the set # of positive integers: # n -> n/2 (n is even) # n -> 3n + 1 (n is odd) # Using the rule above and starting with 13, we generate # the following sequence: # 13 40 20 10 5 16 8 4 2 1 # It can be seen that this sequence (starting at 13 and # finishing at 1) contains 10 terms. Although it has not # been proved yet (Collatz Problem), it is thought that all # starting numbers finish at 1. Which starting number, # under one million, produces the longest chain? # NOTE: Once the chain starts the terms are allowed to go # above one million. import time start = time.time() def collatz_length(n): # 0 and 1 return self as length if n <= 1: return n length = 1 while (n != 1): if (n % 2 == 0): n /= 2 else: n = 3*n + 1 length += 1 return length starting_number, longest_chain = 1, 0 for x in xrange(1, 1000001): l = collatz_length(x) if l > longest_chain: starting_number, longest_chain = x, l print starting_number print longest_chain # Slow 31 seconds print "Elapsed Time:", (time.time() - start) * 1000, "millisecs" a=raw_input('Press return to continue')

• Scaling background without scaling foreground in platformer?

  - by David Xu

  I'm currently developing a platform game and I've run into a problem with scaling resolutions. I want a different resolution of the game to still display the foreground unscaled (characters, tiles, etc) but I want the background to be scaled to fit into the window. To explain this better, my viewport has 4 variables: (x, y, width, height) where x and y are the top left corner and width and height are the dimensions. These can be either 800x600, 1024x768 or 1280x960. When I design my levels, I design everything for the highest resolution (1280x960) and expect the game engine to scale it down if a user is running in a lower resolution. I have tried the following to make it work but nothing I've come up with solves it so far: scale = view->width/1280; drawX = x * scale; drawY = y * scale; (this makes the translation too small for low resolution) and scale = view->width/1280; bgWidth = background->width*scale; bgHeight = background->height*scale; drawX = x + background->width/2 - bgWidth/2; drawY = y + background->height/2 - bgHeight/2; (this makes the translation completely wrong at the edges of the map) The thing is, no matter what resolution the game is run at, the map remains the same size, and the foreground is unscaled. (With a lower resolution you just see less of the foreground in the viewport) I was wondering if anyone had any idea how to solve this problem? Thank you in advance!

• Circular dependency and object creation when attempting DDD

  - by Matthew

  I have a domain where an Organization has People. Organization Entity public class Organization { private readonly List<Person> _people = new List<Person>(); public Person CreatePerson(string name) { var person = new Person(organization, name); _people.Add(person); return person; } public IEnumerable<Person> People { get { return _people; } } } Person Entity public class Person { public Person(Organization organization, string name) { if (organization == null) { throw new ArgumentNullException("organization"); } Organization = organization; Name = name; } public Organization { get; private set; } public Name { get; private set; } } The rule for this relationship is that a Person must belong to exactly one Organization. The invariants I want to guarantee are: A person must have an organization this is enforced via the Person's constuctor An organization must know of its people this is why the Organization has a CreatePerson method A person must belong to only one organization this is why the organization's people list is not publicly mutable (ignoring the casting to List, maybe ToEnumerable can enforce that, not too concerned about it though) What I want out of this is that if a person is created, that the organization knows about its creation. However, the problem with the model currently is that you are able to create a person without ever adding it to the organizations collection. Here's a failing unit-test to describe my problem [Test] public void AnOrganizationMustKnowOfItsPeople() { var organization = new Organization(); var person = new Person(organization, "Steve McQueen"); CollectionAssert.Contains(organization.People, person); } What is the most idiomatic way to enforce the invariants and the circular relationship?

• Events and objects being skipped in GameMaker

  - by skeletalmonkey

  Update: Turns out it's not an issue with this code (or at least not entirely). Somehow the objects I use for keylogging and player automation (basic ai that plays the game) are being 'skipped' or not loaded about half the time. These are invisible objects in a room that have basic effects such are simulating button presses, or logging them. I don't know how to better explain this problem without putting up all my code, so unless someone has heard of this issue I guess I'll be banging my head against the desk for a bit /Update I've been continuing work on modifying Spelunky, but I've run into a pretty major issue with GameMaker, which I hope is me just doing something wrong. I have the code below, which is supposed to write log files named sequentially. It's placed in a End Room event such that when a player finishes a level, it'll write all their keypress's to file. The problem is that it randomly skips files, and when it reaches about 30 logs it stops creating any new files. var file_name; file_count = 4; file_name = file_find_first("logs/*.txt", 0); while (file_name != "") { file_count += 1; file_name = file_find_next(); } file_find_close(); file = file_text_open_write("logs/log" + string(file_count) + ".txt"); for(i = 0; i < ds_list_size(keyCodes); i += 1) { file_text_write_string(file, string(ds_list_find_value(keyCodes, i))); file_text_write_string(file, " "); file_text_write_string(file, string(ds_list_find_value(keyTimes, i))); file_text_writeln(file); } file_text_close(file); My best guess is that the first counting loop is taking too long and the whole thing is getting dropped? Also, if anyone can tell me of a better way to have sequentially numbered log files that would also be great. Log files have to continue counting over multiple start/stops of the game.

• Is Joel Test really a good gauging tool?

  - by henry

  I just learned about Joel Test. I have been computer programmer for 22 years, but somehow never heard about it before. I consider my best job so far to be this small investment managing company with 30 employees and only 3 people in IT department. I am no longer with them but I had being working there for 5 years – my longest streak with any given company. To my surprise they scored extremely poor on Joel Test. The only two questions I would answer “yes” are #4: Do you have a bug database? And #9: Do you use the best tools money can buy? Everything else is either “sometimes” or straight “no”. Here is what I liked about the company however: a) Good pay, they bragged about it to my face and I bragged about it to their face, so it was almost like a family environment. b) I always knew big picture. When writing a code to solve particular problem there were no ambiguity about the business nature of that problem. Even though we did not always had written specs we could ask business users a question anytime, often yelling it across the floor. I could even talk to executives any time I felt like doing it: no appointment necessary. c) Immediate feedback. Once we implement a solution and make business users happy they immediately let us know that, we (programmers) become heroes of the moment. d) No red tape. I could always buy any tools I deem necessary, and design solutions the way my professional judgment dictates. e) Flexibility. If I had mid-day dental appointment that is near my house rather than near the office, I would send email to the company: "FYI: I work from home today". As long as one of 3 IT guys was on the floor (to help traders in case their monitors go dark) they did not care where 2 others are. So the question thus becomes how valuable Joel Test is? Why bother with it?

• Configure WebCenter PS5 with WebCenter Content - Bad Example

  - by Vikram Kurma

  I opened JDeveloper, created a content repository connection with all the required fields. While testing the connection, the connection became successful. But while navigating to the Webcenter Content Connection, I am ( Always use past tense ) getting the following error. Notice the inconsistency in the image resolutions SEVERE: Could not list contents of folder with ID = dCollectionID:-1oracle.stellent.ridc.protocol.ServiceException: No service defined for COLLECTION_DISPLAY. To solve the issue, please find the following the steps in Webcenter Content. 1. Login into webcenter content : https://<hostname>:<port number>/cs 2. Click on 'Administration' and select 'Admin Server' 3. This will open a new window in browser, please select 'Component Manager'. 4. In the right side window, please click on 'Advanced component manager' 5. We can see all the enabled and disabled features. The main problem for this error is folders_g is not enabled and Framework folders might have enabled. But for creating a connection with webcenter portal framework or with webcenter spaces, we need folders_g, then only we will get Contribution folder. 6. come to the enabled feature session, select Framework folders and disable it. 7. Come to the disabled feature session, select folders_g in the list and enable it. 8. Restart the Webcenter content node. 9. Login into webcenter content system, go to 'Browse Content' menu. If we are able to see 'Contribution Folder' the problem is solved. ( Avoid dubious sentences ) We can configure webcenter content with Webcenter portal framework or with webcenter spaces.

• Is it possible to implement an infinite IEnumerable without using yield with only C# code?

  - by sinelaw

  This isn't a practical problem, it's more of a riddle. Problem I'm curious to know if there's a way to implement something equivalent to the following, but without using yield: IEnumerable<T> Infinite<T>() { while (true) { yield return default(T); } } Rules You can't use the yield keyword Use only C# itself directly - no IL code, no constructing dynamic assemblies etc. You can only use the basic .NET lib (only mscorlib.dll, System.Core.dll? not sure what else to include). However if you find a solution with some of the other .NET assemblies (WPF?!), I'm also interested. Don't implement IEnumerable or IEnumerator. Notes The closest I've come yet: IEnumerable<int> infinite = null; infinite = new int[1].SelectMany(x => new int[1].Concat(infinite)); This is "correct" but hits a StackOverflowException after 14399 iterations through the enumerable (not quite infinite). I'm thinking there might be no way to do this due to the CLR's lack of tail recursion optimization. A proof would be nice :)

• Unit testing ASP.NET Web API controllers that rely on the UrlHelper

  - by cibrax

  UrlHelper is the class you can use in ASP.NET Web API to automatically infer links from the routing table without hardcoding anything. For example, the following code uses the helper to infer the location url for a new resource,public HttpResponseMessage Post(User model) { var response = Request.CreateResponse(HttpStatusCode.Created, user); var link = Url.Link("DefaultApi", new { id = id, controller = "Users" }); response.Headers.Location = new Uri(link); return response; } That code uses a previously defined route “DefaultApi”, which you might configure in the HttpConfiguration object (This is the route generated by default when you create a new Web API project). The problem with UrlHelper is that it requires from some initialization code before you can invoking it from a unit test (for testing the Post method in this example). If you don’t initialize the HttpConfiguration and Request instances associated to the controller from the unit test, it will fail miserably. After digging into the ASP.NET Web API source code a little bit, I could figure out what the requirements for using the UrlHelper are. It relies on the routing table configuration, and a few properties you need to add to the HttpRequestMessage. The following code illustrates what’s needed,var controller = new UserController(); controller.Configuration = new HttpConfiguration(); var route = controller.Configuration.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "id", "1" }, { "controller", "Users" } } ); controller.Request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:9091/"); controller.Request.Properties.Add(HttpPropertyKeys.HttpConfigurationKey, controller.Configuration); controller.Request.Properties.Add(HttpPropertyKeys.HttpRouteDataKey, routeData);  The HttpRouteData instance should be initialized with the route values you will use in the controller method (“id” and “controller” in this example). Once you have correctly setup all those properties, you shouldn’t have any problem to use the UrlHelper. There is no need to mock anything else. Enjoy!!.

• Problems with both LightDM and GDM using DisplayLink USB monitor

  - by Austin

  When I use LightDM, it will auto-login to desktop just fine. The only problem is Compiz doesn't work, and menus don't work. I can't right-click the desktop, and I can't select program menus in the top bar (I.e clicking "File" does nothing). When I use GDM, I only get a blank blue screen and the mouse cursor. I can't Ctrl+Alt+Backspace to restart, but I can Ctrl+Alt+F1 and Ctrl+Alt+F7 to switch modes. I don't think it's auto-logging me in, but I'm not sure. It plays the login screen noise. Will update with more information when I get home! EDIT: Okay, so I did a fresh install, just to ensure I hadn't borked something playing in the console. I reconfigured my setup as I did before, with the same results. Here's what I followed. The only difference is that instead of setting "vga=normal nomodeset" I set "GRUB_GFXPAYLOAD_LINUX = text". Also I only have the DisplayLink monitor configured in my xorg.conf file. At this point I'm using the open radeon driver, although I used the proprietary ati driver before. I'm not sure if I'm having a problem with: - X configuration - Graphics driver - DisplayLink driver - Unity - LightDM - Compiz - Or something else The resolution of the monitor is 800x480, 16bit. I tried setting a larger virtual resolution of 1200x720 (because the real resolution is lower than the recommended resolution), but it causes Ubuntu to boot into low graphics mode. When I get home I'm going to install the fglrx driver and see if it enables virtual resolutions, which may further enable my window manager to function properly.

• If not gamedev, what do I do !

  - by brainydexter

  Hi, I am a game dev who was working in the game-industry and then..got laid off. Ever since then, life couldn't get less stressful! During this time, I have met so many other devs who have also been laid off irrespective of the number of years they have been in the game. Now, the problem really gets worse, since I am not a US citizen (yes, I am in US) , and am on an international visa here, I might have to soon pack my bags and go back to my native country. Going back is not bad at all, apart from the fact, that gamedev is still in a very nascent stage there. There just aren't many opportunities. So, employment is the key to maintain a valid visa status. After giving it a lot of thought, I am thinking of staying away from gamedev jobs for the time being, given its job unstablity. This brings me to my current problem. I can't think of a domain/place where I can use my game development skills. I know graphics/simulation/visualization is huge, but I can't think straight and am left clueless where to go from here. What are some of the domains/companies where I can use my skills ? I'd appreciate any insight on this (and I apologize if this is not the place to post this kind of a question).

• Which data structure should I use for dynamically generated platforms?

  - by Joey Green

  I'm creating a platform type of game with various types of platforms. Platforms that move, shake, rotate, etc. Multiple types and multiple of each type can be on the screen at once. The platforms will be procedural generated. I'm trying to figure out which of the following would be a better platform system: Pre-allocate all platforms when the scene loads, storing each platform type into different platform type arrays( i.e. regPlatformArray ), and just getting one when I need one. The other option is to allocate and load what I need when my code needs it. The problem with 1 is keeping up with the indices that are in use on screen and which aren't. The problem with 2 is I'm having a hard time wrapping my head around how I would store these platforms so that I can call the update/draw methods on them and managing that data structure that holds them. The data structure would constantly be growing and shrinking. It seems there could be too much complexity. I'm using the cocos2d iPhone game engine. Anyways, which option would be best or is there a better option?

• Unable to Connect to Internet with 3G USB Dongle for Particular ISP

  - by Kush

  I'm using USB 3G Dongle for Internet. Previously I was using Tata Docomo (India) as provider, and the Internet was working fine. Now I've changed to BSNL, but I'm unable to connect to the Internet on Ubuntu. However, I've checked access point settings and other configuration which are required for BSNL, and it is working fine with same Dongle on Windows 7. Also, I'm able to connect Internet with other providers on Ubuntu, but problem persists only with Ubuntu. The access point for BSNL in my region is bsnlnet. In fact I configure the Dongle with BSNL using default Network Configuration wizard that pops up when USB Dongle is attached. When Dongle is attached and configured with BSNL, I can see network strength in Messaging menu, in Mobile Broadband category, of Ubuntu (note: my network icon still shows "not connected" status). And when I try to use the connection that I've created, it fails to connect. So far, I tried using Sakis3g script that I came up with while wandering over this issue on other forums, it didn't worked either. I also made sure that there are no special configuration made for BSNL on my Windows 7 installation, and still it is working fine there, the problem is only with Ubuntu. How can I fix it?

• How do I enable sound with the "linux-virtual" kernel?

  - by Ola Tuvesson

  I've been trying to enable sound for the linux-virtual kernel as I want to run an ultra slim Ubuntu server under VirtualBox but need audio. The resource usage difference between virtual and generic/server is surprisingly large, with the virtual kernel system using 80Mb less RAM after a clean boot (130Mb vs 210Mb), and I really want to squeeze every clock cycle and available byte I can out of the system. Besides, the virtual kernel has some additional optimisations enabled specifically for virtual machines (or so I am told). Now I have compiled my own kernel a few times in the past, for example to include the Intel-PHC module (for improved power management on Thinkpads), so the concept is not entirely alien to me, but I've run into a strange problem which I'm hoping someone can help explain: When I do a diff between the config files for Linux-generic and Linux-virtual there are precious few differences, and certainly none which pertain to sound support; there are really only five or six lines which differ, and they're mainly to do with i/o timing, sleep state and priorities. What gives? I expected the differences to be extensive, and that I would be able to identify the options that enabled audio by looking at them, but my problem doesn't seem to be related to the config file at all (yes, I know about the sound drivers section - it is identical between the two kernel configs). Am I looking in the wrong place? Many thanks!

• Geometry Shader: distortions

  - by Christophe Lionet

  This is a cross-question from Stack Overflow, I thought it would be more appropriate here. There is a lot of code I could be posting. To avoid overloading the page with code, I will post any part of the code if requested. I am working from the ParticleGS DirectX10 sample, to build a geometry shader based particle system in DirectX 11. Using the sample code, and changing it to my liking, I am able to draw a single quad (which is essentially one particle constantly recreating itself). However, I noticed a problem which was similar to one I once had: the rendered shape is distorted. Here is a video showcasing what is happening. http://youtu.be/6NY_hxjMfwY Now, I used to have this issue when using several effects together, when I realised that I needed to explicitely set the geometry shader to null for the other effects. I solved this problem, as you can see in the video, as the rest of the scene is drawing properly. Note that some sides are being culled somehow, although I turned off culling in my main render state. The texturing is fine too, the texture draws with appropriate proportions relative to the quad. I really don't see what I could be doing wrong here... what would cause the geometry shader to behave in such a way? Again, I will post any piece code you will request.

• SQL Query for Determining SharePoint ACL Sizes

  - by Damon Armstrong

  When a SharePoint Access Control List (ACL) size exceeds more than 64kb for a particular URL, the contents under that URL become unsearchable due to limitations in the SharePoint search engine.  The error most often seen is The Parameter is Incorrect which really helps to pinpoint the problem (its difficult to convey extreme sarcasm here, please note that it is intended).  Exceeding this limit is not unheard of – it can happen when users brute force security into working by continually overriding inherited permissions and assigning user-level access to securable objects. Once you have this issue, determining where you need to focus to fix the problem can be difficult.  Fortunately, there is a query that you can run on a content database that can help identify the issue: SELECT [SiteId],      MIN([ScopeUrl]) AS URL,      SUM(DATALENGTH([Acl]))/1024 as AclSizeKB,      COUNT(*) AS AclEntries FROM [Perms] (NOLOCK) GROUP BY siteid ORDER BY AclSizeKB DESC This query results in a list of ACL sizes and entry counts on a site-by-site basis.  You can also remove grouping to see a more granular breakdown: SELECT [ScopeUrl] AS URL,       SUM(DATALENGTH([Acl]))/1024 as AclSizeKB,      COUNT(*) AS AclEntries FROM [Perms] (NOLOCK) GROUP BY ScopeUrl ORDER BY AclSizeKB DESC

• Connection timeout when accessing Github

  - by Felipe Micaroni Lalli

  I have exactly the same problem as described here: http://stackoverflow.com/questions/12849986/connection-timeout-when-accessing-github So I'll just copy & paste: I have some weird problems. When I try to log in my Github account, I get a "net::ERR_EMPTY_RESPONSE" error. I tried with Chrome, Firefox and Opera. In Firefox, if a clean the cache and offline data, it works for a while. Then I can log in, but I still can't create a Github repository, even if I clear the cache again. My friend, in the same network, with Windows, can do whatever he wants on Github's web site, but I can't. I tried many DNS servers, I tried not to set it (my friend doesn't), but it's still not working. My OS: Ubuntu x64 12.04 Ideas, please. And thanks. Also, I can clone any repo but I can't push. I had to change to https://codeplane.com/ due to this problem, but I want to understand why it happens. EDIT: I could clone one repo, but the other one just hangs at this point: felipelalli@felipelalli-Studio-XPS-8100:~/wa$ git clone [email protected]:felipelalli/micaroni.git Cloning into 'micaroni'... remote: Counting objects: 5238, done. remote: Compressing objects: 100% (3257/3257), done.

• How to diagnose and fix Kernel Panic Fatal Machine Check error?

  - by 0x4a6f4672

  I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. A fine machine comparable to a Macbook Pro. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following Machine Check Exception error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-( I also disabled the Execute Disable Bit (EDB) flag in the BIOS. EDB is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. Since I disabled it, the error did occur less frequently, but it still appears occasionally :-( It seems to be the same error as described here and here. Maybe a Samsung specific Kernel problem? A similar error also happens on a Samsung Ultrabook Series 9 (which seems to be kernel bugs 49161 and 47121). At my Samsung Series 7, it still occurs for instance during booting on battery after "Checking battery state". Perhaps anyone else has an idea? These Kernel Panic errors are reallly annoying..
