• VBScript Multiple folder check if then statement

  - by user2868186

  I had this working before just fine with the exception of getting an error if one of the folders was not there, so I tried to fix it. Searched for a while (as much as I can at work) for a solution and tried different methods, still no luck and my IT tickets are stacking up at work, lol, woohoo. Thanks for any help provided. Getting syntax error on line 60 character 60, thanks again.

• PowerShell Script to Deploy Multiple VM on Azure in Parallel #azure #powershell

  - by Marco Russo (SQLBI)

  This blog is usually dedicated to Business Intelligence and SQL Server, but I didn’t found easily on the web simple PowerShell scripts to help me deploying a number of virtual machines on Azure that I use for testing and development. Since I need to deploy, start, stop and remove many virtual machines created from a common image I created (you know, Tabular is not part of the standard images provided by Microsoft…), I wanted to minimize the time required to execute every operation from my Windows Azure PowerShell console (but I suggest you using Windows PowerShell ISE), so I also wanted to fire the commands as soon as possible in parallel, without losing the result in the console. In order to execute multiple commands in parallel, I used the Start-Job cmdlet, and using Get-Job and Receive-Job I wait for job completion and display the messages generated during background command execution. This technique allows me to reduce execution time when I have to deploy, start, stop or remove virtual machines. Please note that a few operations on Azure acquire an exclusive lock and cannot be really executed in parallel, but only one part of their execution time is subject to this lock. Thus, you obtain a better response time also in these scenarios (this is the case of the provisioning of a new VM). Finally, when you remove the VMs you still have the disk containing the virtual machine to remove. This cannot be done just after the VM removal, because you have to wait that the removal operation is completed on Azure. So I wrote a script that you have to run a few minutes after VMs removal and delete disks (and VHD) no longer related to a VM. I just check that the disk were associated to the original image name used to provision the VMs (so I don’t remove other disks deployed by other batches that I might want to preserve). These examples are specific for my scenario, if you need more complex configurations you have to change and adapt the code. But if your need is to create multiple instances of the same VM running in a workgroup, these scripts should be good enough. I prepared the following PowerShell scripts: ProvisionVMs: Provision many VMs in parallel starting from the same image. It creates one service for each VM. RemoveVMs: Remove all the VMs in parallel – it also remove the service created for the VM StartVMs: Starts all the VMs in parallel StopVMs: Stops all the VMs in parallel RemoveOrphanDisks: Remove all the disks no longer used by any VMs. Run this script a few minutes after RemoveVMs script. ProvisionVMs # Name of subscription $SubscriptionName = "Copy the SubscriptionName property you get from Get-AzureSubscription"   # Name of storage account (where VMs will be deployed) $StorageAccount = "Copy the Label property you get from Get-AzureStorageAccount"   function ProvisionVM( [string]$VmName ) {     Start-Job -ArgumentList $VmName {         param($VmName) $Location = "Copy the Location property you get from Get-AzureStorageAccount" $InstanceSize = "A5" # You can use any other instance, such as Large, A6, and so on $AdminUsername = "UserName" # Write the name of the administrator account in the new VM $Password = "Password"      # Write the password of the administrator account in the new VM $Image = "Copy the ImageName property you get from Get-AzureVMImage" # You can list your own images using the following command: # Get-AzureVMImage | Where-Object {$_.PublisherName -eq "User" }         New-AzureVMConfig -Name $VmName -ImageName $Image -InstanceSize $InstanceSize |             Add-AzureProvisioningConfig -Windows -Password $Password -AdminUsername $AdminUsername|             New-AzureVM -Location $Location -ServiceName "$VmName" -Verbose     } }   # Set the proper storage -

• Dim an Overly Bright Alarm Clock with a Binder Divider

  - by ETC

  Love your alarm clock but hate how eye-searingly bright it is? Slice up a plastic binder divider to dim your alarm clock (or any other aggressively bright monochromatic display). At DIY site Curbly Chris Job shares a simple alarm clock hack. For years he had an alarm clock with a nice dim display. When it broke he went in search of a replacement but failed to find one that wasn’t . His solution came in form of a sliced up binder divider (the clear, usually tinted, plastic tabs you put in between paper in a binder). He sliced to fit the display, spritzed it with a little water to help it cling to the plastic, and pressed it in place. The plastic dims the display enough–as seen in the before/after picture above–that he doesn’t need to cover it up to get a good night’s sleep.

• Mission 26 Captures Endeavour’s Last Trip in Stop Motion

  - by Jason Fitzpatrick

  On September 21, 2012 the Space Shuttle Endeavour was delivered to the Los Angeles International Airport and spent the next three days being slowly transported 12 miles to the California Science Center. One dedicated team of photographers captured the whole thing. Lead by Matthew Givot, the group followed the shuttle for three straight days, photographing it around the clock. The Endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town. No matter how many times I would see the Shuttle it would never get old. This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy. The end result of their labor is the above video, a beautiful time-lapse video of Endeavour’s journey from the airport to its hanger at the California Science Center.

• Multithreading in Windows Phone 7 emulator: A bug

  - by Laurent Bugnion

  Multithreading is supported in Windows Phone 7 Silverlight applications, however the emulator has a bug (which I discovered and was confirmed to me by the dev lead of the emulator team): If you attempt to start a background thread in the MainPage constructor, the thread never starts. The reason is a problem with the emulator UI thread which doesn’t leave any time to the background thread to start. Thankfully there is a workaround (see code below). Also, the bug should be corrected in a future release, so it’s not a big deal, even though it is really confusing when you try to understand why the *%&^$£% thread is not &$%&%$£ starting (that was me in the plane the other day ;) This code does not work: public partial class MainPage : PhoneApplicationPage { public MainPage() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape; var counter = 0; ThreadPool.QueueUserWorkItem(o => { while (true) { Dispatcher.BeginInvoke(() => { textBlockListTitle.Text = (counter++).ToString(); }); } }); } } This code does work: public MainPage() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape; var counter = 0; ThreadPool.QueueUserWorkItem(o => { while (true) { Dispatcher.BeginInvoke(() => { textBlockListTitle.Text = (counter++).ToString(); }); // NOTICE THIS LINE!!! Thread.Sleep(0); } }); } Note that even if the thread is started in a later event (for example Click of a Button), the behavior without the Thread.Sleep(0) is not good in the emulator. As of now, i would recommend always sleeping when starting a new thread. Happy coding: Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Cluster Nodes as RAID Drives

  - by BuckWoody

  I'm unable to sleep tonight so I thought I would push this post out VERY early. When you don't sleep your mind takes interesting turns, which can be a good thing. I was watching a briefing today by a couple of friends as they were talking about various ways to arrange a Windows Server Cluster for SQL Server. I often see an "active" node of a cluster with a "passive" node backing it up. That means one node is working and accepting transactions, and the other is not doing any work but simply "standing by" waiting for the first to fail over. The configuration in the demonstration I saw was a bit different. In this example, there were three nodes that were actively working, and a fourth standing by for all three. I've put configurations like this one into place before, but as I was looking at their architecture diagram, it looked familar - it looked like a RAID drive setup! And that's not a bad way to think about your cluster arrangements. The same concerns you might think about for a particular RAID configuration provides a good way to think about protecting your systems in general. So even if you're not staying awake all night thinking about SQL Server clusters, take this post as an opportunity for "lateral thinking" - a way of combining in your mind the concepts from one piece of knowledge to another. You might find a new way of making your technical environment a little better. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• How to Handle frame rates and synchronizing screen repaints

  - by David Kroukamp

  I would first off say sorry if the title is worded incorrectly. Okay now let me give the scenario I'm creating a 2 player fighting game, An average battle will include a Map (moving/still) and 2 characters (which are rendered by redrawing a varying amount of sprites one after the other). Now at the moment I have a single game loop limiting me to a set number of frames per second (using Java): Timer timer = new Timer(0, new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { long beginTime; //The time when the cycle begun long timeDiff; //The time it took for the cycle to execute int sleepTime; //ms to sleep (< 0 if we're behind) int fps = 1000 / 40; beginTime = System.nanoTime() / 1000000; //execute loop to update check collisions and draw gameLoop(); //Calculate how long did the cycle take timeDiff = System.nanoTime() / 1000000 - beginTime; //Calculate sleep time sleepTime = fps - (int) (timeDiff); if (sleepTime > 0) {//If sleepTime > 0 we're OK ((Timer)e.getSource()).setDelay(sleepTime); } } }); timer.start(); in gameLoop() characters are drawn to the screen ( a character holds an array of images which consists of their current sprites) every gameLoop() call will change the characters current sprite to the next and loop if the end is reached. But as you can imagine if a sprite is only 3 images in length than calling gameLoop() 40 times will cause the characters movement to be drawn 40/3=13 times. This causes a few minor anomilies in the sprited for some charcters So my question is how would I go about delivering a set amount of frames per second in when I have 2 characters on screen with varying amount of sprites?

Then goes the lunch, but the IS session over shoot for 15 minutes so our idea of taking a nap in lunch was not working out, but anyway we did our lunch and tried to sleep for 10-15 minutes. We got back and session on International Business started. Frankly, it’s a great topic, but we had tough time to be attentive, and it was hard to keep ourselves awake :P Anyhow the session came to an end, and we went to Library, and roamed around campus. Got back, had dinner, and went for a night walk, and ice-cream party. Lastly we did went to the platform inside the lake, and had a gag session, got back and  did “ITC eChaupal” case study. We have planned to visit Kali Mandir tomorrow, so I’ve to sleep for few hours…GN! Stay tuned for more… ram :)

• Launching php script through comman line - keeping terminal window open after execution

  - by somethis

  Oh, my girlfriend really likes it when I launch php scripts! There's something special about them, she says ... Thus, I coded this script to run throught the CLI (Command Line Interface) - so it's running locally, not on a web server. It launches just fine through right click open run in terminal but closes right after execution. **Is there a way to keep the terminal window open? Of course I can launch it through a terminal window - which would stay open - but I'm looking for a one click action. With bash scripts I use $SHELL but that didn't work (see code below). So far, the only thing I came up with is sleep(10); which gives me 10 seconds for my girl to check the output. I'd rather close the terminal window manually, though. #!/usr/bin/php -q <?php echo "Hello World \n"; # wait before closing terminal window sleep(10); # the following line doesn't work $SHELL; ?> (PHP 5.4.6-1ubuntu1.2 (cli) (built: Mar 11 2013 14:57:54) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies )

• 12.10 upgrade broke brightness keys [closed]

  - by Chris Morgan

  I have been running Ubuntu (64-bit) on my HP 6710b laptop (Core 2 Duo with integrated graphics) for several years, and the backlight brightness keys have always worked. Since I upgraded to Ubuntu 12.10 earlier today, those keys do not work any more. The secondary function keys: Fn+F3: sleep; still works (and considerably faster than ever before!) Fn+F8: battery info; still works Fn+F9: reduce brightness; stopped working in 12.10 Fn+F10: increase brightness; stopped working in 12.10 It may also be worth while mentioning that X does not appear to be receiving the brightness events at all, or at least not sending them out further. (This I detected with a key logger I wrote for a Uni project, which uses X's Record extension; it is informed of the sleep and battery info keystrokes, but doesn't receive the brightness ones at all.) In the mean time, I know that I can use the Brightness & Lock settings screen to alter the brightness. (Wow! I can suddenly make my backlight darker than I could before—I can go right down to turning the backlight off, something I couldn't do before... but this model has a fairly dim screen, so I don't expect to use that much, if ever.) How can I get the brightness keys working again? This question is probably strongly related to I can't control my Brightness in HP Compaq 6710s.

• It could be worse....

  - by Darryl Gove

  As "guest" pointed out, in my file I/O test I didn't open the file with O_SYNC, so in fact the time was spent in OS code rather than in disk I/O. It's a straightforward change to add O_SYNC to the open() call, but it's also useful to reduce the iteration count - since the cost per write is much higher: ... #define SIZE 1024 void test_write() { starttime(); int file = open("./test.dat",O_WRONLY|O_CREAT|O_SYNC,S_IWGRP|S_IWOTH|S_IWUSR); ... Running this gave the following results: Time per iteration 0.000065606310 MB/s Time per iteration 2.709711563906 MB/s Time per iteration 0.178590114758 MB/s Yup, disk I/O is way slower than the original I/O calls. However, it's not a very fair comparison since disks get written in large blocks of data and we're deliberately sending a single byte. A fairer result would be to look at the I/O operations per second; which is about 65 - pretty much what I'd expect for this system. It's also interesting to examine at the profiles for the two cases. When the write() was trapping into the OS the profile indicated that all the time was being spent in system. When the data was being written to disk, the time got attributed to sleep. This gives us an indication how to interpret profiles from apps doing I/O. It's the sleep time that indicates disk activity.

• How exactly to implement multiple threads in a game

  - by xerwin

  So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Problems after installing a plethora of updates

  - by box

  yesterday I decided to install 32-bit Ubuntu on my 64-bit desktop, first of all, is that a problem? After installing, i had around 270 updates to install, according to the update manager. I was having trouble launching a game with WINE, so I thought updating might help. After updating, I restarted my computer, and after a long while it showed me my desktop and the icon's on it, but I didn't get anything else. I didn't have the "taskbar" (not sure what it's called, sue me) on the left side, nor the bar at the top. I also received an error message saying some program had stopped working. I decided to restart my computer again, and that was when it told me that i have to re-configure my drivers, or run in "Low Graphics" mode for one session, amongst other options. Well, I decided to try to revert to the "basic video drivers", which was an option it gave. Restarting the computer gave me the same problem as in the second paragraph. After a few more restarts and a night of restless sleep, here I am trying to start my computer again, only to receive a black screen, and my monitor "going to sleep". I'm sort of stumped here, being new to Ubuntu (desktop, at least) and I really hope this gets fixed without me having to install Ubuntu on yet another partition (I have three other partitions for various things already) tl;dr: Black screen on boot after installing updates.

• About output of vga_switcher

  - by zhangjie

  When IGD and DIS both exist in my pc,and I want to disable DIS,so I create a service to switch on and off the DIS.It works.Finally,I decide to add the service command into /etc/rc.local so that DIS will be powered off automatically.Unfortunately,it fails.There's only one command added by myself in the file /etc/rc.local,so I can affirm failure is caused by that added command. Before,I directly added the command "echo OFF /sys/kernel/debug..." into /etc/rc.local,and when I restarted,the system startup fails.So I thought maybe when the command is executed,the DIS hasn't been powered on or ready for work.So conflict occurs!It's just my prediction.Then I added one line command "sleep 1s" before the "echo OFF ...",it works nearly everytime when I start or restart pc,while fails sometimes. The output result of "cat /sys/kernel/debug..." is as following: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 I want know 0000:00:02.0 means what?Time of first power on? If it was really time,I can set the command "sleep 2s" to wait for DIS powered on then "echo OFF ..." Thanks for your advice!

• C++/CLI HTTP Proxy problems...

  - by darkantimatter

  Hi, I'm trying(very hard) to make a small HTTP Proxy server which I can use to save all communications to a file. Seeing as I dont really have any experience in the area, I used a class from codeproject.com and some associated code to get started (It was made in the old CLI syntax, so I converted it). I couldn't get it working, so I added lots more code to make it work (threads etc), and now it sort of works. Basically, it recieves something from a client (I just configured Mozilla Firefox to route its connections through this proxy) and then routes it to google.com. After it sends Mozilla's data to google, recieves a responce, and sends that to Mozilla. This works fine, but then the proxy fails to recieve any data from Mozilla. It just loops in the Sleep(50) section. Anyway, heres the code: ProxyTest.cpp: #include "stdafx.h" #include "windows.h" #include "CHTTPProxy.h" public ref class ClientThread { public: System::Net::Sockets::TcpClient ^ pClient; CHttpProxy ^ pProxy; System::Int32 ^ pRecieveBufferSize; System::Threading::Thread ^ Thread; ClientThread(System::Net::Sockets::TcpClient ^ sClient, CHttpProxy ^ sProxy, System::Int32 ^ sRecieveBufferSize) { pClient = sClient; pProxy = sProxy; pRecieveBufferSize = sRecieveBufferSize; }; void StartReading() { Thread = gcnew System::Threading::Thread(gcnew System::Threading::ThreadStart(this,&ClientThread::ThreadEntryPoint)); Thread->Start(); }; void ThreadEntryPoint() { char * bytess; bytess = new char[(int)pRecieveBufferSize]; memset(bytess, 0, (int)pRecieveBufferSize); array<unsigned char> ^ bytes = gcnew array<unsigned char>((int)pRecieveBufferSize); array<unsigned char> ^ sendbytes; do { if (pClient->GetStream()->DataAvailable) { try { do { Sleep(100); //Lets wait for whole packet to get cached (If it even does...) unsigned int k = pClient->GetStream()->Read(bytes, 0, (int)pRecieveBufferSize); //Read it for(unsigned int i=0; i<(int)pRecieveBufferSize; i++) bytess[i] = bytes[i]; Console::WriteLine("Packet Received:\n"+gcnew System::String(bytess)); pProxy->SendToServer(bytes,pClient->GetStream()); //Now send it to google! pClient->GetStream()->Flush(); } while(pClient->GetStream()->DataAvailable); } catch (Exception ^ e) { break; } } else { Sleep(50); //It just loops here because it thinks mozilla isnt sending anything if (!(pClient->Connected)) break; }; } while (pClient->GetStream()->CanRead); delete [] bytess; pClient->Close(); }; }; int main(array<System::String ^> ^args) { System::Collections::Generic::Stack<ClientThread ^> ^ Clients = gcnew System::Collections::Generic::Stack<ClientThread ^>(); System::Net::Sockets::TcpListener ^ pTcpListener = gcnew System::Net::Sockets::TcpListener(8080); pTcpListener->Start(); System::Net::Sockets::TcpClient ^ pTcpClient; while (1) { pTcpClient = pTcpListener->AcceptTcpClient(); //Wait for client ClientThread ^ Client = gcnew ClientThread(pTcpClient, gcnew CHttpProxy("www.google.com.au", 80), pTcpClient->ReceiveBufferSize); //Make a new object for this client Client->StartReading(); //Start the thread Clients->Push(Client); //Add it to the list }; pTcpListener->Stop(); return 0; } CHTTPProxy.h, from http://www.codeproject.com/KB/IP/howtoproxy.aspx with a lot of modifications: //THIS FILE IS FROM http://www.codeproject.com/KB/IP/howtoproxy.aspx. I DID NOT MAKE THIS! BUT I HAVE MADE SEVERAL MODIFICATIONS! #using <mscorlib.dll> #using <SYSTEM.DLL> using namespace System; using System::Net::Sockets::TcpClient; using System::String; using System::Exception; using System::Net::Sockets::NetworkStream; #include <stdio.h> ref class CHttpProxy { public: CHttpProxy(System::String ^ szHost, int port); System::String ^ m_host; int m_port; void SendToServer(array<unsigned char> ^ Packet, System::Net::Sockets::NetworkStream ^ sendstr); }; CHttpProxy::CHttpProxy(System::String ^ szHost, int port) { m_host = gcnew System::String(szHost); m_port = port; } void CHttpProxy::SendToServer(array<unsigned char> ^ Packet, System::Net::Sockets::NetworkStream ^ sendstr) { TcpClient ^ tcpclnt = gcnew TcpClient(); try { tcpclnt->Connect(m_host,m_port); } catch (Exception ^ e ) { Console::WriteLine(e->ToString()); return; } // Send it if ( tcpclnt ) { NetworkStream ^ networkStream; networkStream = tcpclnt->GetStream(); int size = Packet->Length; networkStream->Write(Packet, 0, size); array<unsigned char> ^ bytes = gcnew array<unsigned char>(tcpclnt->ReceiveBufferSize); char * bytess = new char[tcpclnt->ReceiveBufferSize]; Sleep(500); //Wait for responce do { unsigned int k = networkStream->Read(bytes, 0, (int)tcpclnt->ReceiveBufferSize); //Read from google for(unsigned int i=0; i<k; i++) { bytess[i] = bytes[i]; if (bytess[i] == 0) bytess[i] = ' '; //Dont terminate the string if (bytess[i] < 8) bytess[i] = ' '; //Somethings making the computer beep, and its not 7?!?! }; Console::WriteLine("\n\nAbove packet sent to google. Google Packet Received:\n"+gcnew System::String(bytess)); sendstr->Write(bytes,0,k); //Send it to mozilla Console::WriteLine("\n\nAbove packet sent to client..."); //Sleep(1000); } while(networkStream->DataAvailable); delete [] bytess; } return; } Any help would be much appreciated, I've tried for hours.

• What must one know when approaching web development?

  - by Tal Koren

  I just started working as a novice Web Developer. I know PHP pretty well, as well as some basic jQuery. Anyway, my boss told me I should explore and learn about MVC, Memcache, Design Patterns, how Apache servers work and how to set one up etc. What I want to ask is actually this: What should I learn further? Web Development is a big area and most odds are that I'll never stop learning, but what are the basics I should learn about? What are the fundamentals? Currently I'm focusing on Server Side Development, but a very big part of me also wants to become a front-end ninja, so please consider that in your comments. Thanks in advance, you rock. :)

• Install ubuntu-11.10-desktop-amd64 with Logitech diNovo Edge

  - by MyGGaN

  I know there are problems (and have been for quite some time) with the diNovo Edge keyboard. The solution could be found easily and often you can use the on-screen keyboard to fix it. Now I'm installing Ubuntu from scratch and the only keyboard I have is my diNovo, am I screwed? You are able to get to System Config during the install process and from there to Accessibility menu where you usually can start the on-screen keyboard. This doesn't work, no keyboard in sight... What if I can do some ninja copy-paste with the mouse?? Nope, no pasting allowed in the feilds: username, password, etc. Is there a chance I can fix this somehow within the .iso file before I create the bootable USB drive I use to install from? Or do I have to buy a keyboard to be able to install Ubuntu?
