• How to Architect a system on AWS for scaling (with a MySQL back-end)

  - by Edan Maor

  I'm trying to understand how to architect an Amazon Web Services application. As I understand it, the whole point of using something like AWS is to make the eventual scaling easier, so I'm trying to understand how to do that. I have an instance, running off of EBS (EBS-based instance, not a regular instance). My application (a Django app) uses MySQL as a back-end. So the question is, where am I supposed to install the MySQL? Do I install it on the same instance? In which case, as far as I can tell, I can't simply create more server instances from that image. Or am I supposed to simply spin up another server as a DB server, and run off of that? Thanks for any help!

• Different Servers for incoming mails

  - by André

  Hi everybody, not sure if what I want is possible so I´d appreciate any pointers. I have full control over the infrastructure (DNS and servers) Currently I receive mails for domain.tld. MX record for domain.tld is gw.domain.tld. gw then does some spam and virus checking and forwards the mails to the internal exchange server. GW is a Proxmox Mail Gateway Box (Free license) Now what I want is to distribute mails for different recipients to other mail servers. Basicly I only want [email protected] and [email protected] to go to the exchange as before, but all others go to a different mail server (based on linux). Any idea how I could achieve this?

• SOA: Simplifying Cloud, Mobile, and On-premise Integration–Webcast October 24th 2013

  - by JuergenKress

  Proliferation of mobile devices, data explosion, and cloud enablement has caused a dramatic shift in IT. Organizations need to rethink their application infrastructures to accommodate increased processing speeds, heightened security and availability concerns for their applications, all while meeting lowered total cost of ownership. Traditional infrastructures may not be sufficient to accommodate the diversity and complexity of integrations in this new era. Many of today’s IT organizations rely on a Service Oriented Architecture (SOA) backbone to keep their businesses running. SOA adoption and acceptance across industries have led to platform maturity at the application layer level. However, we are at the start of an era where there is a new modus operandi for organizations to thrive and deliver continuously on competitive differentiation. This change is a result of market globalization, explosion in the number of mobile devices, unparalleled growth in voluminous data and innovation that crosses organizational boundaries. Social, mobile, cloud are terms that are revolutionizing the way organizations operate. Oracle SOA Suite is a hot-pluggable software suite to build, deploy and manage Service-Oriented Architectures (SOA).Oracle SOA transforms complex application integration into agile and reusable service-based connectivity by mediating, routing, and managing interactions between services and applications in the enterprise and in the cloud. Oracle SOA Suite's hot-pluggable architecture helps businesses lower upfront costs by allowing maximum re-use of existing IT investments and assets. Join us on this webcast to find out how you can optimize the use of Oracle SOA Suite, simplifying integration, and what does the next generation of SOA has to offer to you. Agenda: What's new in Oracle SOA Simplifying integration Application Integration and SOA Cloud integration with SOA Mobile Integration leveraging Oracle SOA Suite Oracle Delivers on Next Generation SOA Customer Examples Summary and Q&A Webcast Thursday October 24th, 2013 10am CET (8am UTC / 11am EEST)Details at the Registration Page SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• Resume on 30 Days of SharePoint

  Dear readers, as you might have noticed... It was an organisational desaster on my end! Even though I continued my studies and research on Microsoft SharePoint 2013 during the last 30 days, I wasn't able to write an article a day to keep you posted on my progress. Nonetheless, I gathered a good number of additional blogs, mainly SharePoint MVP sites, and online forums which will be helpful in the next couple of weeks while I'm actually going to develop a C#-based client which will enable an existing 'legacy' application to SharePoint as a document management system (DMS) besides other already existing solutions. Finding excuses Well, no. Not really. I simply didn't block any or enough time every day to write down my progress during my own challenge. My log book on learning about SharePoint stands at 41 hours and 15 minutes during this month. Which means that I spent an average of more than 1 hour per day on getting into SharePoint. I know that might sound a little bit low but also keep in mind that I went for the challenge on top of my daily job and private responsibilities. During the same period there had been two priority 0 incidents from clients - external root cause - which took presedence over this leisure project. More to come Anyway, it was a first trial and despite the low level of reporting on my blog, I'm confident about what I learned during the last 30 days, and I'm ready to implement the client's requirements. At least, I would say that I have a better understanding about the road map or the path to walk during the next month. As time and secrecy allows I'm going to note down some bits and pieces... During the process of development, I'm going to 'cheat' on the challenge summary article and add links to those new entries. Just for the sake of completeness. Next challenge? Hmm, there had been ideas during the last meetup of the Mauritius Software Craftsmanship Community (MSCC) regarding certifications in IT and eventually we might organise some kind of a study group for specific exams, most probably Microsoft exams towards MCSD Web Developer or Windows Developer.

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• touch detection of non-rectangular sprites (cocos2d)

  - by hogni89

  What is the correct way to implement a non-rectangular sprite in Cocos2d? I am working on a jigsaw puzzle. And therefor do our sprites have some strange forms (Jigsaw puzzle bricks). As of now, we have implemented the "detect" this way: - (void)selectSpriteForTouch:(CGPoint)touchLocation { CCSprite * newSprite = nil; // Loop array of sprites for (CCSprite *sprite in movableSprites) { // Check if sprite is hit. // TODO: Swap if with something better. if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) { newSprite = sprite; break; } } if (newSprite != selSprite) { // Move along, nothing to see here // Not the problem } } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; [self selectSpriteForTouch:touchLocation]; return TRUE; } I know that the problem is in the keyword "sprite.boundingBox". Is there a better way of implementing this, OR is it a limit when using sprites based on .png's? If so, how should I proceed? I'm new to iPhone and game development :D

• Recommend a Rackspace Cloud Server API Language Binding?

  - by Alex R

  Rackspace publishes only a hard-to-use HTTP and JSON/XML based "API" (they call it an API but it's really a non-standard Web Service without a WSDL). There are dozens of open-source language bindings to choose from. I have tried three of them so far and they're all horrible (incomplete, buggy, and/or undocumented). Can anybody recommend a language binding which is reasonably complete, well documented, and bug-free? I can use Perl, Python, PHP, or Java. My ultimate objective is to create a script/program that will provision a server, launch a process inside it, wait for the process to finish, copy the results to the local server, and destroy the remote server. What's the best choice for that? Thanks

• Rendering artifact when using Eclipse (FlashBuilder)

  - by Demian Brecht

  Once in a while when using FlashBuilder, I'll get a rendering artifact that doesn't go away until I do a full reboot. This artifact seems to be caused by a popup triggered by code documentation popups (hovering over keywords) that linger after the popup has been dismissed: This behavior is seemingly random and incredibly annoying. It only happens when using Eclipse (although I don't run many Java-based programs) and run an NVidia Quadro 2000M (with the latest drivers - figured I'd try that before posting). Has anyone else encountered this issue? Any known solutions?

• How can I make Bash (or Zsh) run a particular command before each entered command?

  - by Peeja

  I'd like to configure Bash to run a particular command before running each command line I enter at the prompt. Specifically, I'd like to tell Vim (which is running in another terminal) to write all open buffers, because in my workflow if anything's unsaved when I leave Vim it's a mistake. Is there an option for this in Bash? If not, is there an option in Zsh? (There is a readline-based solution that somewhat fits this problem on another question, but it feels a bit hacky. It'll take it as a last resort.)

• Good practices when optimizing HTML5/Javascript Game Developement [closed]

  - by hustlerinc

  I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

• How to pass an interface to Java from Unity code?

  - by nickbadal

  First, let me say that this is my first experience with Unity, so the answer may be right under my nose. I've also posted this question on Unity's answers site, but plugin questions don't seem to be as frequently answered there. I'm trying to create a plugin that allows me to access an SDK from my game. I can call SDK methods just fine using AndroidJavaObject and I can pass data to them with no issue. But there are some SDK methods that require an interface to be passed. For example, my Java function: public void attemptLogin(String username, String password, LoginListener listener); Where listener; is a callback interface. I would normally run this code from Java as such: attemptLogin("username", "password", new LoginListener() { @Override public void onSuccess() { //Yay! do some stuff in the game } @Override public void onFailure(int error) { //Uh oh, find out what happened based on error } }); Is there a way to pass a C# interface through JNI/Unity to my attemptLogin function? Or is there a way to create a mimic-ing interface in C# that I can call from inside the Java code (and pass in any kind of parameter)? Thanks in advance! :)

• Find keyword values from PDF [closed]

  - by JukkaA

  I have a lot of PDF reports I'd need to index. They're mostly "text-based PDFs", not images. I know they all have account number in certain format, 123456AAAAA and some other keyword info like addresses, customer names etc. needed in indexing these files. Basically if the file is ab.pdf, I need to create ab.txt that contains: ACC=123456AAAA Customer=John Doe Date=20120808 What would be the best software/solution to generate indexing information for these? I know there's pdftotext, but piping it to different grep/awk commands is a hack... It would be nice to specify an area in PDF to search for the account number, and specify the format it is in.

• How can we tell what driven the Private bytes spiking.

  - by ronin

  I have websites running on .Net Framework 2.0 environment. For recent every day my website becomes slow at certain time and I need to recycle my app pool. I checked the log file found that the private bytes will spike during that time slot. Through some research I already know that the managed code and unmanaged code consists of Privates and we can identify which one cause the spike based on "Bytes in all heaps" counter. But I can't find a way to dig deeper. Is there any way that I can find out what driven my private bytes spike? How can we see what the private bytes are being used for? Thanks, Ronin

• Windows Server Backup 2008 - Language Incompatibilities?

  - by Chris Walters

  I have 2 Windows 2008 Server R2 machines - one is Japanese language based and the other English. When I try to connect from the English language server using Windows Server Backup (snap-in) I get the following message: "An internal error has occurred in the backup engine or the computer that you are connected to remotely is running a version of backup application that is not compatible with the version on your local computer" Both claim to be running Version 1 of Windows Server Backup. Is remote connection to non-identical language server OSs a known problem? Specifically this is seen when attempting the "Connect To Another Server" in the action pane of Windows Server Backup.

• How to change color of a cell in one sheet if its value increases or decreases from another cell value in a different sheet

  - by Sean Coffey

  I am putting together a workbook with 52 sheets for the weeks in the year. In this workbook there are multiple columns for percentages on each sheet. I want to be able to change the color of each cell based on whethernit increases (green) or decreases (red) from the same cell in the previous sheet. I have the formula i.e. =IF(ISERROR(B4/D4),"0", B4/D4) to calculate my percentages but I don't know how to put the reference in for this change. Any help?

• What to do if you were scammed by a web hosting company? [on hold]

  - by Cain Nuke

  I was recently scammed by a web hosting company. Is there anything i can do about it? I would like to sue them but that doesn't sound realistic to me since they are not based on the same country as me. I would like to at least be able to have them blacklisted or something so other people don't get scammed too. I would appreciate if you can tell me how to proceed in these cases. They promise 24/7 support which is not true because its only one guy managing the whole thing and your server can go down for days and he doesn't do anything, he wont even reply your tickets. My server is been offline for over a week now and he only ignores me. I paid for this month and shortly after that my server went offline. I used Paypal to pay. He is in Bulgaria (that's what he says) i'm in Japan. I paid $55 USD.

• virsh console and tty size

  - by pehrs

  I have a virtualization server to which I connect over ssh. If I now change the size of the window it will automatically propagate to the server. It's most easily seen using stty -a, checking the columns and row values. I then use virsh console to connect to the serial interface on a KVM based virtual machine. When I now change the size of the window it does not propagate to the virtual server. This is most easily seen by checking stty -a, which is not updated on the virtual machine when I change window size. This means that line breaks does not work correctly in the terminal and any application that relies on window size for formatting (emacs, man, etc) gets messed up unless the window size on the client matches the default size on the server. A workaround is to manually set the window size to match the client window using stty, but I wonder if there is any way to get this information to propagate and set the window size in the virtual machine automatically.

• What are people using as Login scripts in large enterprises

  - by beakersoft

  Hi, We have recently been tasked with looking after the user login side of things in our enterprise (windows clients in active directory). We have a system at the moment that uses a vbscript login/loggof script to call a couple of DLL written in vb 6. The DLL's actions are controled by some config files based on users/groups witch is administrated from a central app. This is quite a good system, but kind of want to come away from vb6 for the dll's (maybe port them to c++ but them you have to make them com+ to call them from vbscripts etc) and possibly away from vbscript for the actual login scripts themselves. Just wondered what other people are using, what people can suggest etc Thanks Luke

• How to convert non key, value java arguments to applet params? (args like -Xmx64m)

  - by bwizzy

  I'm trying to use xvpviewer (based on TightVNC) to VNC into my VMs running on Citirx XenServer. There are a couple of caveats required with trusting the certificate from XenServer which I've got working. Essentially I'm trying to convert the java command below (which works on the command line to launch VncViewer) for use in an applet that can be accessed via HTML page. java -Djavax.net.ssl.trustStore=/tmp/kimo.jks -Xmx64m -jar VncViewer.jar HOST "/console?ref=OpaqueRef:141f4204-2240-4627-69c6-a0c7d9898e6a&session_id=OpaqueRef:91a483c4-bc40-3bb0-121c-93f2f89acc3c" PORT 443 PROXYHOST1 192.168.0.5 PROXYPORT1 443 SocketFactory "HTTPSConnectSocketFactory" I know I can put the HOST, PORT etc arguments into param tags for the applet but I'm not sure how to apply the two initial argments.

• Debian 6 or CentOS 6 - which one is easiest for latest versions of Ruby and Postgres?

  - by A4J

  I am getting a new server as I've messed up my current box, while trying to install Postgres 9 (on my CentOS 5.8 box). To cut a long story short, I removed postgres but yum decided to remove virtualmin-base as well, which broke my virtualmin install (postfix/dovcot stopped working). Virtualmin advise a fresh install once virtualmin-base has been removed/reinstalled. So I'll probably make a decision based on this simple criteria: which distro out of the two makes it easiest for installing the latest versions of Ruby and Postgres? They are both equally respected as web servers, so I really don't mind either way - I just want to use the one that will work best with the software I need.

• Jumbo Frames on DIR-655

  - by Spookyone

  I am trying to set up jumbo frames on my gigabit home LAN but no luck so far. My setup is: D-Link DIR-655 router, HW Revision A3, Firmware 1.21 EU Synology DS107+, Firmware 3.0-1337 Laptop w/ Win7 x64, external PCIx NIC managed by "Generic Marvel Yukon 88E8053 based Ethernet Controller" The router is supposed to support jumbo frames but doesn't feature any relevant setting. I set the Jumbo Packet value to 9000 on both the NIC and the Synobox but it doesn't work, ping -f -l 8972 says "Packet needs to be fragmented but DF set". Is there any other setting I overlooked, the DIR-655 doesn't actually support jumbo frames, or what else could be the problem?

• Access Control Service: Programmatically Accessing Identity Provider Information and Redirect URLs

  - by Your DisplayName here!

  In my last post I showed you that different redirect URLs trigger different response behaviors in ACS. Where did I actually get these URLs from? The answer is simple – I asked ACS ;) ACS publishes a JSON encoded feed that contains information about all registered identity providers, their display names, logos and URLs. With that information you can easily write a discovery client which, at the very heart, does this: public void GetAsync(string protocol) {     var url = string.Format( "https://{0}.{1}/v2/metadata/IdentityProviders.js?protocol={2}&realm={3}&version=1.0",         AcsNamespace,         "accesscontrol.windows.net",         protocol,         Realm);     _client.DownloadStringAsync(new Uri(url)); } The protocol can be one of these two values: wsfederation or javascriptnotify. Based on that value, the returned JSON will contain the URLs for either the redirect or notify method. Now with the help of some JSON serializer you can turn that information into CLR objects and display them in some sort of selection dialog. The next post will have a demo and source code.

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do. Thanks!

• Computer Says No: Mobile Apps Connectivity Messages

  - by ultan o'broin

  Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".
