Replicate GAE Datastore On A Server LAN in Java

- by Franz Noel

There may be instances wherein one Company Client may not have internet connection on their vicinity. Either their Internet Service Provider currently experience a down time or there are some other problems involving the network, but not their LAN. GAE seems to be needing a connection at all times in the internet. I only need GAE Datastore. I'm thinking about a different application. Creating a Java Swing Client, for instance, and connecting to the Office Server via HRD of GAE Datastore. When I tried to check on the solutions for Java, it does not say anything about uploading all data and I do not need the App. I just need the GAE Datastore. In Java GAE, only indexes can be able to be manipulated. So, is there any tricks/ideas that you can use HRD with GAE Datastore on Java with an Internal Office Server combined? This way, it may provide service even during network down times. (Can somebody create me a tag of gae-datastore, please.)

PASS Location fixed for the next 2 years - Are they listening?

- by simonsabin

I've just received the PASS connector newsletter with details of the decision of where to locate the next summits. To me it shows you how you can spin statistics they way you want to. I am very suprised by the numbers 81% said that they would like an east coast event. The spin is that "When we look at responses from only 2008 and 2009 Summit attendees (our most successful ones by far), the number who want a future Summit outside of Seattle drops to 69%." Wow the number drops thats bad. We must stay in Seattle then. My take however is that 69% of those willing to travel to Seattle want an event NOT in Seattle. Doesn't that suggest that people would like an event not in Seattle. I appreciate the comment about the launch years however 2012 isn't going to be a launch year because they need to get SQL out of the door before then to meet the 3 year software assurance cycle. So sticking 2012 in Seattle is IMHO a bad decision. It might keep the cost down for the PASS org, Microsoft and the attendees that live near Seattle but does it keep the cost down for the rest of the SQL Community? They do mention a possibility of an event on the East Coast and I do hope that its not just lip service. Flights for me to the East coast look ~30% cheaper than to Seattle and I've never been to the East Coast. Come on PASS show you are listening to the community.

Automatic Appointment Conflict Resolution

- by Thomas

I'm trying to figure out an algorithm for resolving appointment times. I currently have a naive algorithm that pushes down conflicting appointments repeatedly, until there are no more appointments. # The appointment list is always sorted on start time appointment_list = [ <Appointment: 10:00 -> 12:00>, <Appointment: 11:00 -> 12:30>, <Appointment: 13:00 -> 14:00>, <Appointment: 13:30 -> 14:30>, ] Constraints are that appointments: cannot be after 15:00 cannot be before 9:00 This is the naive algorithm for i, app in enumerate(appointment_list): for possible_conflict in appointment_list[i+1:]: if possible_conflict.start < app.end: difference = app.end - possible_conflict.start possible_conflict.end += difference possible_conflict.start += difference else: break This results in the following resolution, which obviously breaks those constraints, and the last appointment will have to be pushed to the following day. appointment_list = [ <Appointment: 10:00 -> 12:00>, <Appointment: 12:00 -> 13:30>, <Appointment: 13:30 -> 14:30>, <Appointment: 14:30 -> 15:30>, ] Obviously this is sub-optimal, It performs 3 appointment moves when the confict could have been resolved with one: if we were able to push the first appointment backwards, we could avoid moving all the subsequent appointments down. I'm thinking that there should be a sort of edit-distance approach that would calculate the least number of appointments that should be moved in order to resolve the scheduling conflict, but I can't get the a handle on the methodology. Should it be breadth-first or depth first solution search. When do I know if the solution is "good enough"?

apt-get update very slow, stuck at "Waiting for headers"

- by Liam

I have looked at similar questions: Stuck at 0% [waiting for headers] (apt) apt-get update stuck on "Waiting for Headers" However neither one of them answer my problem. I am running 12.04 AMD64 and have recently started getting an issue that when I update my repos from my connection at home through a terminal, using sudo apt-get update, it takes forever (literally after 2 hours it was at 28%), however when I run from a different location it takes less than 5 minutes to complete. I have attempted changing which mirror I use but that does not solve the issue. I have also cut down what is in my sources list but this also makes no difference. There are no faults on my ADSL line as I have already contacted my ISP to check this. It also makes no difference if I use a WiFi or network cable connection. What could be my issue? A speed test (www.speedtest.net) comes out at about 0.9 Mbps down and 0.42 Mbps up (which is a shade under the advertised line speed), I reside in South Africa and use the UCT LEG server. But I have also tried the other mirrors available in SA....none of them make a difference.

SQL SERVER – Finding Different ColumnName From Almost Identitical Tables

- by pinaldave

I have mentioned earlier on this blog that I love social media – Facebook and Twitter. I receive so many interesting questions that sometimes I wonder how come I never faced them in my real life scenario. Well, let us see one of the similar situation. Here is one of the questions which I received on my social media handle. “Pinal, I have a large database. I did not develop this database but I have inherited this database. In our database we have many tables but all the tables are in pairs. We have one archive table and one current table. Now here is interesting situation. For a while due to some reason our organization has stopped paying attention to archive data. We did not archive anything for a while. If this was not enough we even changed the schema of current table but did not change the corresponding archive table. This is now becoming a huge huge problem. We know for sure that in current table we have added few column but we do not know which ones. Is there any way we can figure out what are the new column added in the current table and does not exist in the archive tables? We cannot use any third party tool. Would you please guide us?” Well here is the interesting example of how we can use sys.column catalogue views and get the details of the newly added column. I have previously written about EXCEPT over here which is very similar to MINUS of Oracle. In following example we are going to create two tables. One of the tables has extra column. In our resultset we will get the name of the extra column as we are comparing the catalogue view of the column name. USE AdventureWorks2012 GO CREATE TABLE ArchiveTable (ID INT, Col1 VARCHAR(10), Col2 VARCHAR(100), Col3 VARCHAR(100)); CREATE TABLE CurrentTable (ID INT, Col1 VARCHAR(10), Col2 VARCHAR(100), Col3 VARCHAR(100), ExtraCol INT); GO -- Columns in ArchiveTable but not in CurrentTable SELECT name ColumnName FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'ArchiveTable' EXCEPT SELECT name ColumnName FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'CurrentTable' GO -- Columns in CurrentTable but not in ArchiveTable SELECT name ColumnName FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'CurrentTable' EXCEPT SELECT name ColumnName FROM sys.columns WHERE OBJECT_NAME(OBJECT_ID) = 'ArchiveTable' GO DROP TABLE ArchiveTable; DROP TABLE CurrentTable; GO The above query will return us following result. I hope this solves the problems. It is not the most elegant solution ever possible but it works. Here is the puzzle back to you – what native T-SQL solution would you have provided in this situation?

XNA RenderTarget2D Sample

- by Michael B. McLaughlin

I remember being scared of render targets when I first started with XNA. They seemed like weird magic and I didn’t understand them at all. There’s nothing to be frightened of, though, and they are pretty easy to learn how to use. The first thing you need to know is that when you’re drawing in XNA, you aren’t actually drawing to the screen. Instead you’re drawing to this thing called the “back buffer”. Internally, XNA maintains two sections of graphics memory. Each one is exactly the same size as the other and has all the same properties (such as surface format, whether there’s a depth buffer and/or a stencil buffer, and so on). XNA flips between these two sections of memory every update-draw cycle. So while you are drawing to one, it’s busy drawing the other one on the screen. Then the current update-draw cycle ends, it flips, and the section you were just drawing to gets drawn to the screen while the one that was being drawn to the screen before is now the one you’ll be drawing on. This is what’s meant by “double buffering”. If you drew directly to the screen, the player would see all of those draws taking place as they happened and that would look odd and not very good at all. Those two sections of graphics memory are render targets. All a render target is, is a section of graphics memory to which things can be drawn. In addition to the two that XNA maintains automatically, you can also create and set your own using RenderTarget2D and GraphicsDevice.SetRenderTarget. Using render targets lets you do all sorts of neat post-processing effects (like bloom) to make your game look cooler. It also just lets you do things like motion blur and lets you create mirrors in 3D games. There are quite a lot of things that render targets let you do. To go along with this post, I wrote up a simple sample for how to create and use a RenderTarget2D. It’s available under the terms of the Microsoft Public License and is available for download on my website here: http://www.bobtacoindustries.com/developers/utils/RenderTarget2DSample.zip . Other than the ‘using’ statements, every line is commented in detail so that it should (hopefully) be easy to follow along with and understand. If you have any questions, leave a comment here or drop me a line on Twitter. One last note. While creating the sample I came across an interesting quirk. If you start by creating a Windows Game, and then make a copy for Windows Phone 7, the drop-down that lets you choose between drawing to a WP7 device and the WP7 emulator stays grayed-out. To resolve this, you need to right click on the Windows Phone 7 version in the Solution Explorer, and choose “Set as StartUp Project”. The bar will then become active, letting you change the target you which to deploy to. If you want another version to be the one that starts up when you press F5 to start debugging, just go and right-click on that version and choose “Set as StartUp Project” for it once you’ve set the WP7 target (device or emulator) that you want.

SQL Server Date Comparison Functions

- by HighAltitudeCoder

A few months ago, I found myself working with a repetitive cursor that looped until the data had been manipulated enough times that it was finally correct. The cursor was heavily dependent upon dates, every time requiring the earlier of two (or several) dates in one stored procedure, while requiring the later of two dates in another stored procedure. In short what I needed was a function that would allow me to perform the following evaluation: WHERE MAX(Date1, Date2) < @SomeDate The problem is, the MAX() function in SQL Server does not perform this functionality. So, I set out to put these functions together. They are titled: EarlierOf() and LaterOf(). /********************************************************** EarlierOf.sql **********************************************************/ /********************************************************** Return the later of two DATETIME variables. Parameter 1: DATETIME1 Parameter 2: DATETIME2 Works for a variety of DATETIME or NULL values. Even though comparisons with NULL are actually indeterminate, we know conceptually that NULL is not earlier or later than any other date provided. SYNTAX: SELECT dbo.EarlierOf('1/1/2000','12/1/2009') SELECT dbo.EarlierOf('2009-12-01 00:00:00.000','2009-12-01 00:00:00.521') SELECT dbo.EarlierOf('11/15/2000',NULL) SELECT dbo.EarlierOf(NULL,'1/15/2004') SELECT dbo.EarlierOf(NULL,NULL) **********************************************************/ USE AdventureWorks GO IF EXISTS (SELECT * FROM sysobjects WHERE name = 'EarlierOf' AND xtype = 'FN' ) BEGIN DROP FUNCTION EarlierOf END GO CREATE FUNCTION EarlierOf ( @Date1 DATETIME, @Date2 DATETIME ) RETURNS DATETIME AS BEGIN DECLARE @ReturnDate DATETIME IF (@Date1 IS NULL AND @Date2 IS NULL) BEGIN SET @ReturnDate = NULL GOTO EndOfFunction END ELSE IF (@Date1 IS NULL AND @Date2 IS NOT NULL) BEGIN SET @ReturnDate = @Date2 GOTO EndOfFunction END ELSE IF (@Date1 IS NOT NULL AND @Date2 IS NULL) BEGIN SET @ReturnDate = @Date1 GOTO EndOfFunction END ELSE BEGIN SET @ReturnDate = @Date1 IF @Date2 < @Date1 SET @ReturnDate = @Date2 GOTO EndOfFunction END EndOfFunction: RETURN @ReturnDate END -- End Function GO ---- Set Permissions --GRANT SELECT ON EarlierOf TO UserRole1 --GRANT SELECT ON EarlierOf TO UserRole2 --GO The inverse of this function is only slightly different. /********************************************************** LaterOf.sql **********************************************************/ /********************************************************** Return the later of two DATETIME variables. Parameter 1: DATETIME1 Parameter 2: DATETIME2 Works for a variety of DATETIME or NULL values. Even though comparisons with NULL are actually indeterminate, we know conceptually that NULL is not earlier or later than any other date provided.

Its interesting, because it seems like something should already exist in SQL Server that does this. From a different vantage point, if you create this functionality and it is easy to use (ideally, intuitively self-explanatory), you have made a successful contribution. Interesting is good. Self-explanatory, or intuitive is FAR better. Happy coding! Graeme

Git pull with unstaged changes

- by Peter

Attempting a git pull when you have unstaged changes will fail, saying you can commit or stash then. I suppose a workaround is to git stash, git pull, then git stash pop. However, is there an alternative way to do this? I would like to forcefully git pull if there are unstaged changes, but only if the files being brought down do not override the modified files? AKA. if I have a repo with the files "derp1", "derp2", "derp3" and modify "derp1" locally, a git pull will bring down and overwrite everything except the "derp1" file. I assume a git stash + pull + stash pop achieves this already? And is there a better way? I suppose this could also work differently if it occurs on a submodule.

Jump handling and gravity

- by sprawl

I'm new to game development and am looking for some help on improving my jump handling for a simple side scrolling game I've made. I would like to make the jump last longer if the key is held down for the full length of the jump, otherwise if the key is tapped, make the jump not as long. Currently, how I'm handling the jumping is the following: Player.prototype.jump = function () { // Player pressed jump key if (this.isJumping === true) { // Set sprite to jump state this.settings.slice = 250; if (this.isFalling === true) { // Player let go of jump key, increase rate of fall this.settings.y -= this.velocity; this.velocity -= this.settings.gravity * 2; } else { // Player is holding down jump key this.settings.y -= this.velocity; this.velocity -= this.settings.gravity; } } if (this.settings.y >= 240) { // Player is on the ground this.isJumping = false; this.isFalling = false; this.velocity = this.settings.maxVelocity; this.settings.y = 240; } } I'm setting isJumping on keydown and isFalling on keyup. While it works okay for simple use, I'm looking for a better way handle jumping and gravity. It's a bit buggy if the gravity is increased (which is why I had to put the last y setting in the last if condition in there) on keyup, so I'd like to know a better way to do it. Where are some resources I could look at that would help me better understand how to handle jumping and gravity? What's a better approach to handling this? Like I said, I'm new to game development so I could be doing it completely wrong. Any help would be appreciated.

Transferring websites from x64 to x86 server

- by Ke

Hi, I run a x64 staging server here along with the following: Solr Java etc. However, I am about to get a linode vps for production and quickly realising that x86 is the way to go for their lowest RAM package (thinking to upgrade later). My staging server is x64 with 12gb ram, so going down to 300mb ram is going to feel devilishly slow ;/ Here are my questions: 1) Will I have problems transferring my scripts, dbs etc from a x64 to x86 server? e.g. solr indexes 2) Is it worth going for the x86 package? I am probably going to upgrade later down the line and x64 might be better for the servers with more RAM? should I stick with x64 instead as there isnt much difference when using with low RAM? Cheers Ke

Input signal out of range; Change settings to 1600 x 900

- by Clayton

I recently installed Ubuntu 12.04 onto my HP Pavilion, in an attempt to make the desktop able to dual-boot Windows 7 and Ubuntu. I managed to get down to the last step, and finished the installation process. After it prompted me to remove what I used to install Ubuntu, I did so, removing my SanDisk 8GB flash drive, and allowed the system to reboot. Like usual, the desktop booted with the HP image, with the options at the bottom(Boot Menu, System Recovery, etc). However, when it should have started up with Ubuntu(like I'm certain it should have done), I received the following error: Input signal out of range Change settings to 1600 x 900 From the time I installed the operating system, back in late August, till now, I've been trying to figure out how I would go about fixing this issue. My mom is also starting to get frustrated with my not having resolved the issue, as its the only desktop that has a printer installed. Is there any possible way to resolve this? To summarize the problem: -Successful boot -Screen brings up error -Screen goes to standby -Nothing else possible until desktop is rebooted, which will initiate the above three steps A few notes: -I did not back up my computer before I installed Ubuntu. I didn't have anything to write to, and basically just forgot to. : -I don't have a Recovery Disk. -I don't have the Windows 7 disk that is supposed to come with the computer. -It has been narrowed down by a friend on Skype that the problem lies with the display, and that the vga= boot command does have something to do with fixing the problem Thank you in advance for resolving this problem. I greatly appreciate it. ^^

Using Groovy Aggregate Functions in ADF BC

- by Sireesha Pinninti

This article explains how groovy aggregate functions(sum, count, min, max and avg) can be used in ADF Business components and demonstrates how these can be used at entity and view level Let's consider EMP and DEPT tables and an usecase to track number of employees in each department Entity-Level To use aggregate functions at entity level, we need to have association between entities representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <Accessor>.count(Groovyexpression) - Note down the destination accessor name(EMP) in the association or AccessorAttribute name in source entity - Add a transient attribute in source entity with persistent property set to false and provide the groovy expression in the syntax provided above - Finally, Add newly added attribute to view object View-Level To use aggregate functions at view level, we need to have a view link between viewobjects representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <ViewLinkAccessor>.count(Groovyexpression) - Note down the destination accessor name(EmpView) in the view link or viewLinkAccessor name in source view - Add a transient attribute in view object and provide a groovy aggregate function count as a value to it in the syntax provided above Now, If you run application module tester and execute DeptView / ViewLink, you should see employee count in EmpCount field In similar way, one can use other groovy aggregate functions sum, avg, min and max.

SQL Server Replication Agent priority

- by Wikser

Every hour a server replicates SQL server data with some external web server. During this time, which takes about 2-5minutes, the database seriously slows down. Colleagues, which work with the front end applications of that on another terminal server, even regularly start complaining. The databases are also synchroniously mirrored (via SQLServer mirroring, no replication) to a third server. Note that 99% of the data is replicated outgoing, so the server should rarely need to update its data. As the (merge and transactional) replication tasks are not time-critical, I would like to reduce their priority or somehow slow them down, so they don't affect the database performance that much. How would you implement that?

The Differences between MAC Address and Network Layer Address

A Mac address is a fixed number associated with a NICs onboard memory. It is initially assigned at the factory. The MAC address is broken up into 2 parts. The first part is the Block id which is six digit sequences that is unique to each vender. The second section is the device id which is created and assigned by the manufacture. A Network layer address is different because there format based on the type of protocol and network used. Also, there unique id is based on a hierarchal addressing theme on subsets of data and narrowing it down. Just like in an address you can narrow down your house, for example: Florida, Boca Raton, 33428, SW 53th street states that you live in Florida. You also live in the area located in Florida called Boca Raton and you are also in the area of 33428 which is located in Boca Raton. Finally you live on SW 8th street which is in the area of 33428 which is located in Boca Raton which is also located in Florida.

I need a relatively cheap host, which will be able to handle sudden peaks in traffic?

- by Morten K

Hello, We're launching a product in a few months, which will obviously have a website. Judging from our current traffic, we believe that overall traffic will probably not be that much, but we are aiming at promoting the site heavily using social media. This has the typical problem, that IF we get suddenly get picked up by a large tech blog, we will see a sudden burst: A very heavy increase in traffic all of the sudden. If we use a cheap charlie host as our current host is (www.unoeuro.com) or something similar like GoDaddy, I'm afraid that the site will go down under the load. If that happens, then we might as well have thrown our social media marketing dollars out of the window. Our site will be relatively lightweight, all videos hosted at Youtube or Vimeo and other than that mainly just a standard webpage (ie nothing too heavy). I am hoping for recommendations for a good hosting company, which has some form of scalable hosting, so if / when a traffic surge hits, the site will not go down.

Problem with Ogre::Camera lookAt function when target is directly below.

- by PigBen

I am trying to make a class which controls a camera. It's pretty basic right now, it looks like this: class HoveringCameraController { public: void init(Ogre::Camera & camera, AnimatedBody & target, Ogre::Real height); void update(Ogre::Real time_delta); private: Ogre::Camera * camera_; AnimatedBody * target_; Ogre::Real height_; }; HoveringCameraController.cpp void HoveringCameraController::init(Ogre::Camera & camera, AnimatedBody & target, Ogre::Real height) { camera_ = &camera; target_ = &target; height_ = height; update(0.0); } void HoveringCameraController::update(Ogre::Real time_delta) { auto position = target_->getPosition(); position.y += height_; camera_->setPosition(position); camera_->lookAt(target_->getPosition()); } AnimatedBody is just a class that encapsulates an entity, it's animations and a scene node. The getPosition function is simply forwarded to it's scene node. What I want(for now) is for the camera to simply follow the AnimatedBody overhead at the distance given(the height parameter), and look down at it. It follows the object around, but it doesn't look straight down, it's tilted quite a bit in the positive Z direction. Does anybody have any idea why it would do that? If I change this line: position.y += height_; to this: position.x += height_; or this: position.z += height_; it does exactly what I would expect. It follows the object from the side or front, and looks directly at it.

Virtual Desktop Provisioning - Vmware View 5.2 Maintenance Questions

- by Lee J. DeAngelis

Currently running an environment of about 400 VMware View 5.2 virtual Desktops. The environment runs pretty efficiently but we sometimes run into problems with certain pools from time to time. Just recently we had a pool that was causing high write latency when users logged in. It just happened all of a sudden and had been working fine for weeks. On a hunch we completely broke down the pool and re-provisioned it from a new image. This corrected the problem. In fact every real issue we've had so far was fixed by a recompose or complete break down and re-provisioning of one pool or another.Our environment consists of Cisco UCS and Netapp 3240s using flashcache running VMware View 5.2. My questions are: What are some maintenance best practices other VDI admins are using? How often are you recomposing? rebalancing? re-provisioning? How long should you keep base image snapshots around?

How to Detect Sprites in a SpriteSheet?

- by IAE

I'm currently writing a Sprite Sheet Unpacker such as Alferds Spritesheet Unpacker. Now, before this is sent to gamedev, this isn't necessarily about games. I would like to know how to detect a sprite within a spriitesheet, or more abstactly, a shape inside of an image. Given this sprite sheet: I want to detect and extract all individual sprites. I've followed the algorithm detailed in Alferd's Blog Post which goes like: Determine predominant color and dub it the BackgroundColor Iterate over each pixel and check ColorAtXY == BackgroundColor If false, we've found a sprite. Keep going right until we find a BackgroundColor again, backtrack one, go down and repeat until a BackgroundColor is reached. Create a box from location to ending location. Repeat this until all sprites are boxed up. Combined overlapping boxes (or within a very short distance) The resulting non-overlapping boxes should contain the sprite. This implementation is fine, especially for small sprite sheets. However, I find the performance too poor for larger sprite sheets and I would like to know what algorithms or techniques can be leveraged to increase the finding of sprites. A second implementation I considered, but have not tested yet, is to find the first pixel, then use a backtracking algorithm to find every connected pixel. This should find a contiguous sprite (breaks down if the sprite is something like an explosion where particles are no longer part of the main sprite). The cool thing is that I can immediately remove a detected sprite from the sprite sheet. Any other suggestions?

Sending an Email from 2 Mail Servers

- by Ted Smith

We are currently attempting to move away from using a "local" mail(exchange) server to an cloud based offering for all our automated emails. The problem is that we send and receive thousands for emails a day and its uptime is quite critical so the business do not want to put all their eggs in one basket, so if we would like to use a cloud based offering(mailgun) they would like a backup if this goes down. So my question is: Would it be possible to set multpile A, TXT and CNAME records to multiple IP address so if one mail server goes down we can automatically start sending emails from the fallover(without them being blocked doing a reverse DNS lookup)? I know we will still need to adjust the MX record for incoming emails but that is acceptable to not receive emails for a short(1-2 hours) of time. Does this make sense?

Website not available everywhere

- by Cedric Reichenbach

Today I noticed my website http://mint-nachhilfe.ch/ was down, but other people (located in different networks) said it looks up from there. When I came home, I double-checked, and I can really reach it from here. Also, this website considers it down. Some facts: It's a Tomcat webapp, connected to an Apache2 server. I restarted both, no change. Another (ruby on rails) application is connected to this Apache2, which I couldn't reach either, but is considered online by above check website. At any point, I could directly connect to the Tomcat over http://mint-nachhilfe.ch:8080! I don't know how to go on searching for the root error. I assume it's related to the Apache2 server, but how could that be?

How to create a password-less service account in AD?

- by Andrew White

Is it possible to create domain accounts that can only be accessed via a domain administrator or similar access? The goal is to create domain users that have certain network access based on their task but these users are only meant for automated jobs. As such, they don't need passwords and a domain admin can always do a run-as to drop down to the correct user to run the job. No password means no chance of someone guessing it or it being written down or lost. This may belong on SuperUser ServerFault but I am going to try here first since it's on the fuzzy border to me. I am also open to constructive alternatives.

Desktop switcher appears to be broken for quick double-switches

- by Jon Blackburn

I'm wondering if anyone else has seen this. I have three virtual desktops aligned in a horizontal row. In the middle desktop I have only a single application window. I have keyboard shortcuts mapping to navigate between the desktops. Obviously, I never use the up/down arrows because I only have one row of workspaces. Here's the problem, which only started to happen after I installed 12.04.1: When I rapidly hit to go from workspace 1 to workspace 3, the window on workspace 2 gets moved to workspace 1. I have checked using both Unity and Gnome3, and the behavior is the same under both. If I change back to the default workspace setup (a 2x2 grid of desktops) things seem to settle down (i.e., no wandering windows). Not every type of application window behaves the same way. I couldn't get a Chrome browser to jump from 2 to 1, but both Terminal and Terminator exhibit the behavior. Any thoughts? Better workarounds? Thanks in advance.

ASA and cisco vs NSA sonic firewall

Currently I’m trying to structure our network to fully support and be redundant with BGP/Multi homing. Our current company size is 40 employees but the major part of that is our Development department. We are a software company and continued connection to the internet is a requirement as 90% of work stops when the net goes down. The only thing hosted on site (that needs to remain up) is our exchange server. Right now i'm faced with 2 different directions and was wondering if I could get your opinions on this. We will have 2 ISPs that are both 20meg up/down and dedicated fiber (so 40megs combined). This is handed off as an Ethernet cable into our server room. ISP#1 first digital ISP#2 CenturyLink we currently have 2x ASA5505s but the 2nd one is not in use. It was there to be a failover and it just needs the security+ license to be matched with the primary device. But this depends on the network structure. I have been looking into the hardware that would be required to be fully redundant and I found that we will either of the following. 2x Cisco 2921+ series routers with failover licenses. They will go in front of the ASAs and either connects in a failover state or 1 ISP into each of the 2921 series routers and then 1 line into each of the ASAs (thus all 4 hardware components will be used actively). So 2x Cisco 2921+ series routers 2x Cisco ASA5505 firewalls The other route 2x SonicWalls NSA2400MX series. 1 primary and the secondary will be in a failover state. This will remove the ASAs from the network and be about 2k cheaper than the cisco route. This also brings down the points of failure because it’s just the 2x sonicwalls It will also allow us to scale all the way up to 200-400 users (depending on their configuration). This also makes so the Sonic walls. So the real question is with the added functionality ect of the sonicwall is there a point in paying so much more to stay the cisco route? Thanks!

Diablo 3 "freezes" periodically

- by Shauna

I'm running Diablo 3 (start edition, digital download) on the following: Ubuntu 12.04 64-bit (stock Unity, Gnome, etc; kernel version 3.2.0-29-generic) Wine version 1.5.11 (base, from Wine's PPA, game started with setarch i386 -3) Intel i7 920 CPU nVidia GTX260 with driver version 295.49 ("post-release updates" entry within the proprietary drivers tool), dual monitors 6GB RAM Every so often (and what appears to be at random), the game video will freeze up. I can still move the mouse, and it reacts to ctrl+alt+f2 to drop into text mode, but I can't get back to the desktop (which means I can check terminal to see what's going on after launching from terminal, especially since even in windowed mode, the secondary screen gets shut off by the game), and I can't continue to play the game. In order to get it running again, I have to restart lightdm, then relaunch the game (or, in a couple of rare cases, I had to restart the computer entirely, because running sudo service lightdmn [stop/start] doesn't appear to react). Turning down the video settings seems to have helped in some cases, but not all of them. Times it's frozen on me: The beginning of The Fallen Start quest part 6 - kill the Wretched Mother, right as you walk out of New Tristram and engage in the monsters on the northern path (repeatedly froze here until I adjusted the graphics down) Within the cinematic/event upon finding Deckard Cain While fighting the skeletons to protect Deckard Cain When about to enter Leoric's passage after Cain sends you back to where you found him That's as far as I've gotten through the game so far. Additionally, this doesn't happen on other games I play and seems to only occur with Diablo 3. Has anyone else run into this issue and know a possible cause or fix, or at least know where I can look (and what to look for) to figure out why this is happening?

What are the necessary periodic checks for server?

- by Edmund

Hi all, I have some server which my team use for hosting internal applications for development purpose. I thinking of setting up some periodic checks but do now know how to go about it. Can advise on the following? Preferably windows bat file or linux script How to write a script that will check the content of a webpage to verify if it is down. How to write a script that will check if the website is down by pinging it How to write a script that will check the diskspace of the server is running out of diskspace. How to write a script that will email back to system administrator if either of the above tasks are not fulfilled?
