• Agile Data Book from O'Reilly Media

  - by Compudicted

  Originally posted on: http://geekswithblogs.net/Compudicted/archive/2013/07/01/153309.aspxAs part of my ongoing self-education and approaching of some free time, yeah, both is a must for every IT person and geek! I have carefully examined the latest trends in the Computersphere with whatever tools I had at my disposal (nothing really fancy was used) and came to a conclusion that for a database pro the *hottest* topic today is undoubtedly the #BigData and all the rapidly growing and spawning ecosystem around it. Having recently immersed myself into the NoSQL world (let me tell here right away NoSQL means Not Only SQL) one book really stood out of the crowd: Book site: http://shop.oreilly.com/product/0636920025054.doDespite being a new book I am sure it will end up on the tables of many Big Data Generalists.In a few dozen words, it is primarily for two reasons:1) The author understands that a  typical business today cannot wait for a Data Scientist for too long to deliver results demanding as usual a very quick turnaround on investments (ROI), and 2) The book covers all the needed and proven modern brick and mortar offerings to get the job done by a relatively newcomer to the Big Data World.It certainly enables such a professional to grow and expand based on the acquired knowledge, and one can truly do it very fast.

• Windows Server 2008 R2 DNS Server not working?

  - by wolfvilleian

  I have a server running Windows Server 2008 R2 hosting a DNS server, exchange 2010 and is a domain controller. One computer on the network (and domain) can ping the server 25% of the time, also when I try to ping it's own hostname it also does not work. However another computer that is on the domain can ping it fine, and another computer on the network but not domain can ping fine as well. The computer that cannot ping the server is setup to use the DNS server running on the server only (secondary dns points to nothing) and it will resolve the hostname of the server to the external IP not internal when the other two computers correctly resolve the internal All 3 computers and server are connected directly into the same switch. Does anyone have any ideas on how to fix this? Thanks

• Exchange ActiveSync does not work for one user

  - by jshin47

  One particular user in our system is unable to connect to Exchange ActiveSync via her iPhone. When I try to connect using my own credentials on her iPhone it works (everything begins syncing), but when I input her credentials, the Settings app verifies the credentials are correct but nothing syncs. For example, if I open Mail, no items are shown. When I attempt to force a sync, it says "Cannot connect to server." In Exchange 2010 Management Console the user is no different than the others. Exchange ActiveSync is set as "Enable" in Mailbox Features. EDIT: Alternatively, if there is some easy way to create a new useraccount/mailbox and copy all of the contents of the old one over, I bet it would work, and that would be fine as well. She is a Mac user so we do not have to worry about her Active Directory account.

• Dell 620 display is too bright to use

  - by keith

  I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

• Interview question: How would you implement Google Search?

  - by ripper234

  Supposed you were asked in an interview "How would you implement Google Search?" How would you answer such a question? There might be resources out there that explain how some pieces in Google are implemented (BigTable, MapReduce, PageRank, ...), but that doesn't exactly fit in an interview. What overall architecture would you use, and how would you explain this in a 15-30 minute time span? I would start with explaining how to build a search engine that handles ~ 100k documents, then expand this via sharding to around 50M docs, then perhaps another architectural/technical leap. This is the 20,000 feet view. What I'd like is the details - how you would actually answer that in an interview. Which data structures would you use. What services/machines is your architecture composed of. What would a typical query latency be? What about failover / split brain issues? Etc...

• More about JuJu cache

  - by koxon

  I would like to know more about JuJu cache. After I start a charm and JuJu provisions a machine for the first time, the charm will be downloaded and all dependencies installed (apt-get, etc). This process can be very long. Once the charm has been build, configured and deployed once, can JuJu provision more instances of the same charm pre-built and configured? I presume that's what the cache is for, but the documentation is not very explicit: https://juju.ubuntu.com/docs/charms-deploying.html How JuJu tracks the state of the charm if it works that way? Thanks Nic

• Recent update killed unity 3d launcher

  I am scratching my head on this one, a lot of things are still new to me.

• Static HTML to Wordpress Migration SEO Implications?

  - by Kayle

  Recently, I migrated a client's site to a new server and a new home within wordpress so they could more easily edit their website and start a blog section. The static site was 10 years old a was showing up at place #3 for it's primary keyword, consistently, according to my client, and has dropped to rank #6-8 following the migration. At launch, we made sure the urls were identical (save the removal of ".htm" which we used 301 redirects to compensate for) and we generated a new XML map and pinged google with the new site. We keep a 404 log to make sure we're not losing any incoming links. We also have Google Webmaster Tools on this site and have zero errors/suggestions, everything seems ok. I was told by numerous sources that Google would not penalize us for the use of 301s, but it's the only thing I can think of right now that is different about the site, other than the platform. Any ideas about what we could be getting docked for?

• Skype webcam not working in 12.04

  - by To Do

  I have a logitech quickcam messenger that was working fine until I upgraded to Ubuntu 12.04. I had to use preload v4l hack but since then it always worked for three consecutive ubuntu versions. Now, when I start the webcam during a call, it works for a few seconds, then it freezes, sortof resets and starts updating the image every 5 seconds, like a slide show. If I go to options and test the video it works fine. The webcam works fine as well with google talk. Does anybody have the same problem?

• Powershell SQL query--connection string

  - by sean

  I am trying to query several different SQL servers and run a command on each of them. I am unable to get the connection string right. Code, below. I receive the following error:Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. I thought if I passed it the credentials it wouldn't care about the domain. How do I get around this? Thanks in advance. $serverList = @(Get-Content "c:\AllServers.txt") $query = "SELECT COUNT(thing) AS [RowCount] FROM My_table" $Database = "My_DB" # Read a file foreach ( $svr in $serverList ) { $conn=new-object System.Data.SqlClient.SQLConnection $ConnectionString = "Server={0};Database={1};User ID=sa;Password=Password;Integrated Security=True" -f $svr, $Database $conn.ConnectionString=$ConnectionString $conn.Open() $cmd=new-object system.Data.SqlClient.SqlCommand($Query,$conn) $conn.Close() }

• How do they keep track of the NPCs in Left 4 Dead?

  - by f20k

  How do they keep track of the NPC zombies in Left 4 Dead? I am talking about the NPCs that just walk into walls or wander around aimlessly. Even though the players cannot see them, they are there (say inside rooms or behind doors). Let's say there's about 10 or so zombies in a hallway and inside rooms. Does the game keep all of those zombies in a list and iterate through giving them commands? Do they just spawn when the user is within a certain radius or reached a special location? Say you placed the 4 units (controlled by players) on completely different places throughout the map. Let's assume you aren't being swarmed and then you have not killed any of these aimless NPCs. Would the game be keeping track of 10 x 4 = 40 zombies in total? Or is my understanding completely off? The reason I ask is if I were to implement something similar on a mobile device, keeping track of 40 or more NPCs might not be such a great idea.

• reg delete gives me "access is denied" but regedit delete is ok

  - by Radek

  I need to delete a key from a command line. So I wanted to use reg delete "the key to be deleted" /f but I get ERROR: access is denied. From the same login session (the same user) I am able to delete the key without any troubles from regedit.exe that is not run as administrator. I cannot use runas command to execute reg that I believe would be to solution because in fact I want to use reg to delete registry entry for administrator profile so runas works again. More info in my other question Windows7 corrupted profile - prevention exists?

• RDS Replication across regions

  - by Bryan Migliorisi

  We are using Amazon AWS for our web services but given the recent instabilities in their infrastructure, we are trying to figure out how to run our application across multiple regions for additional redundancy. Ideally, we would run our entire app in a active-active configuration in multiple regions but our main concern is that we are using RDS, which I understand cannot replicate across regions. One possible solution (though we have not tried or proven it would work) would be to do mysqldump or EBS snapshots every hour or so but this would mean that we would be forced to run in an active-passive configuration. Our data would be at most an hour behind. This carries its own issues around data synchronization when we failover and the master comes back up, so its not the best solution. Are there any proven solutions for replicating RDS across regions?

• Break a hard link of a file in use

  - by Stebi

  I used hard links to merge duplicated files on my SSD (space is still precious) and now have a weird problem. Common files like msvcr110.dll got hard linked. Now I want to delete a program which has this file in its installation directory. But I cannot because this file (on another location) is used by a currently running application (don't know which) and windows doesn't allow me to delete this file because it's in use. I can rename the file but it still points to the same file, so not possible to delete it. Is there any way to break a the hard link of a file which is currently in use? I currently use a trash folder where I move those files to so I can delete the directory structure of program to be deleted. But I'd like to get rid of this leftover (although it doesn't take much space as it's a hard link).

• Remote Access to Owncloud Server

  - by John

  I'm currently trying to setup my own own-cloud server, and I've got it fully installed, configured, and accessible from within my own local network. I cannot figure out how to access it from the outside. So far I've: Successfully setup port-forwarding on my local router. I've done so via 'single port forwarding' and 'port range forwarding' Ports 80, 443, 3306 (Apache-Full and MySQL) Successfully obtained my external IP address. I've also tested this magic number from within the network at #insertIPhere/owncloud and it did work. Successfully setup the server using SQLite Successfully setup the server using MySQL Created the following exceptions in my firewall: Allow In Port 80 (Apache Full) Allow In Port 443 (Apache Full) Allow In Port 3306 (MySQL) Tried connecting from several different remote networks, as to troubleshoot something on their end As far as trying to access it, I'm doing so through Google-Chrome and Mozilla Firefox trying to reach the server through #insertIPhere/owncloud using the above public IP address. So what have I missed, and how do I access my server from outside? Thanks in advance for your help and time, and I apologize in advance for what will probably result in my noobish mistake in networking. I've looked at the official documentation. And also this question here.

• Virtualbox Ubuntu 10.04 on Windows 7: networking won't work

  - by Herbert Roitblat

  I have a virtualbox image that I created using libvirt from Ubuntu 10.04. It assigns a fixed IP address. I can start it up on my Windows 7 VirtualBox, but I cannot get networking to work. My colleague loaded the same image onto his Windows 7 and networking worked as a bridged connection. Therefore, I know that the image is good, it must be something about my Windows 7 installation. Any thoughts on where to look to get networking running in my virtual machine? Thanks, Herb

• How to deal with OpenGL and Fullscreen on OS X

  - by Armin Ronacher

  I do most of my development on OS X and for my current game project this is my target environment. However when I play games I play on Windows. As a windows gamer I am used to Alt+Tab switching from within the game to the last application that was open. On OS X I currently can't find either a game that supports that nor can I find a way to make it possible. My current project is based on SDL 1.3 and I can see that cmd+tab is a sequence that is sent directly to my application and not intercepted by the operating system. Now my first attempt was to hide the rendering window on cmd+tab which certainly works, but has the disadvantage that a hidden OpenGL window in SDL cannot be restored when the user tabs back to the application. First of all, there is no event fired for that or I can't find it, secondly the core problem is that when that application window is hidden, my game is still the active application, just that the window disappeared. That is incredible annoying. Any ideas how to approximate the windows / linux behavior for alt+tab?

• Profiling Startup Of VS2012 &ndash; YourKit Profiler

  - by Alois Kraus

  The YourKit (v7.0.5) profiler is interesting in terms of price (79€ single place license, 409€ + 1 year support and upgrades) and feature set. You do get a performance and memory profiler in one package for which you normally need also to pay extra from the other vendors. As an interesting side note the profiler UI is written in Java because they do also sell Java profilers with the same feature set. To get all methods of a VS startup you need first to configure it to include System* in the profiled methods and you need to configure * to measure wall clock time. By default it does record only CPU times which allows you to optimize CPU hungry operations. But you will never see a Thread.Sleep(10000) in the profiler blocking the UI in this mode. It can profile as all others processes started from within the profiler but it can also profile the next or all started processes. As usual it can profile in sampling and tracing mode. But since it is a memory profiler as well it does by default also record all object allocations > 1MB. With allocation recording enabled VS2012 did crash but without allocation recording there were no problems. The CPU tab contains the time line of the application and when you click in the graph you the call stacks of all threads at this time. This is really a nice feature. When you select a time region you the CPU Usage estimation for this time window. I have seen many applications consuming 100% CPU only because they did create garbage like crazy. For this is the Garbage Collection tab interesting in conjunction with a time range. This view is like the CPU table only that the CPU graph (green) is missing. All relevant information except for GCs/s is already visible in the CPU tab. Very handy to pinpoint excessive GC or CPU bound issues. The Threads tab does show the thread names and their lifetime. This is useful to see thread interactions or which thread is hottest in terms of CPU consumption. On the CPU tab the call tree does exist in a merged and thread specific view. When you click on a method you get below a list of all called methods. There you can sort for methods with a high own time which are worth optimizing. In the Method List you can select which scope you want to see. Back Traces are the methods which did call you. Callees ist the list of methods called directly or indirectly by your method as a flat list. This is not a call stack but still very useful to see which methods were slow so you can see the “root” cause quite quickly without the need to click trough long call stacks. The last view Merged Calles is a call stacked view of the previous view. This does help a lot to understand did call each method at run time. You would get the same view with a debugger for one call invocation but here you get the full statistics (invocation count) as well. Since YourKit is also a memory profiler you can directly see which objects you have on your managed heap and which objects do hold most of your precious memory. You can in in the Object Explorer view also examine the contents of your objects (strings or whatsoever) to get a better understanding which objects where potentially allocating this stuff.   YourKit is a very easy to use combined memory and performance profiler in one product. The unbeatable single license price makes it very attractive to straightly buy it. Although it is a Java UI it is very responsive and the memory consumption is considerably lower compared to dotTrace and ANTS profiler. What I do really like is to start the YourKit ui and then start the processes I want to profile as usual. There is no need to alter your own application code to be able to inject a profiler into your new started processes. For performance and memory profiling you can simply select the process you want to investigate from the list of started processes. That's the way I like to use profilers. Just get out of the way and let the application run without any special preparations.   Next: Telerik JustTrace

• Exchange Public Folders in Snow Leopard Mail.app

  - by W_P

  I am using Mail.app (running snow leopard) to connect to my email account on my school's Exchange 2007 server. I get my Inbox just fine, and iCal connects to my Outlook Calendar just fine, but I cannot seem to get any of the Exchange Public Folders that I can automatically see when I am using Outlook on a Windows box. The Account Type is shown as "Exchange 2007" I did not have any luck Googling this problem, in fact most of the results I saw were dealing with the opposite problem: Remove MS Exchange Public Folders I am aware that my question is a duplicate of this: http://superuser.com/questions/103115/apple-mail-app-all-exchange-folders-not-visible but since that question did not get any responses, I am reposting.

• Victory rewards in digital CCG

  - by Nils Munch

  I am currently polishing a digital CCG where people can play against friend and random opponents in a classical Magic the Gathering-like duel CCG. I plan to award the players with 20 ingame currency units (lets call them gold) for each hour they are playing, 50 for each day they are playing and X for each victory. Now, the X is what I am trying to calculate here, since I would prefer keeping the currency to a certain value, but also with to entice the players to battle. I could go with a solid figure, say 25, for beating up an opponent. But that would result in experienced players only beating up newly started players, making the experience lame for both. I could also make a laddered tier, where you start at level 1, and raise in level as you defeat your opponents, where winning over a player awards you his level x 2 in gold. Which would you prefer if you were playing a game like this. There is no gold-based scoreboard, but the gold is used to purchase new cards along the way.

• Permissions needed to read event log messages remotely?

  - by Neolisk

  When running under a limited account, local event log messages are displaying fine, for remote computer I am getting this error: The description for Event ID ( xxxxx ) in Source ( yyyyy ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: zzzzz. Same remote computer works fine under domain administrator. I am currently experimenting with just the Event Viewer, by using Run As. Original issue is a PowerShell script which does Get-EventLog. Are there any special permissions that need to be in place to able to read event log messages remotely? Supposedly there is a simple solution in Windows 2008 and higher, i.e. just add user to Event Log Readers group. Is there anything like that for Windows 2003?

• What technology should I concentrate on for mobile development? [closed]

  - by Rob2211

  Firstly, I have many years experience with C# & .NET and some with Java. But, rather than committing to Java and developing native applications for Andriod I have been researching cross-platform deployment technologies. Currently, the most powerful cross-platform technology seems to be Flash, using Adobe AIR to package software as native applications. But given Adobe's announcement that it will discontinue support for the Flash Player on mobile devices it seems foolish (at this late stage) to invest in Flash and ActionScript as a developer. There has been speculation that Microsoft are also planning their exit strategy for Silverlight in favour of HTML5. So, my questions are; What is the most appropriate technology to invest in and learn in order to build cross-platform mobile applications / games while future proofing my skills as a developer? Is HTML5 mature enough to fill the 'Flash void' and be used to start building cross-platform, rich, interactive, networked mobile applications / games now? N.B. For HTML5 read (HTML5/CSS3/JavaScript)
