• How to highlight non-rectengular hotspots?

  - by HuseyinUslu

  So my question is highly related to Creating non-rectangular hotspots and detecting clicks. Yet again, I've irregular hot-spots (think the game Risk). So basically, we can detect clicks on these hot-spots easily using color key mapping as discussed in above question which I don't have any problems implementing (which is also covered here in details). The problem is about highlighting these irreguar hotspots. So let me explain the question a bit more - the above color key mapping guide uses this as a world map; then the author color-maps the imaginary countries; which we can now detect the country the pointer is over. In the same article author mentions outlining countries on mouse-over; though to get the effect, he creates unique border assets for each country - like; So for the game I'm working on I'm using the same color-key mapping idea to detect hot-spots, but I didn't like the way of highlighting hot-spots. Coloring all the hot-spots is already a great work for me - as I've 25+ hot-spots for each map - further more the need to have 25 unique border/highlight asset per hot-spot doesn't sound right. Anyone have a better idea/suggestion on highlighting these hot-spots?

• Contractor - Mispaid again - Walked out

  - by MeshMan

  Hi all, I'm wondering whether or not I've done the right thing as a contractor. Basically I'm in to my 3rd month, and my current client messed up the payment in the first month, and I just found out that they are again late in paying me for my 2nd month. It wouldn't be so bad if I wasn't in a bit of a financial situation due to this being my first contract experience. But as a matter of principal, I walked out on them and will be telling them that I will not be going back in until they resolve the pay. Part of me feels as though this was not a very professional thing to do, but I also don't feel that it was very professional for them to mess my payments up, twice in a row. Did I make the right decision? I still want to work for these guys and enjoy the job, but I have a life to attend to that requires finances and I can't afford to keep getting messed up with pay like this. I attempted to phrase the question to be oriented around contractors behaviour around clients that mis-treat them, and as some of the answers that have been posted so far, it's a good discussion. The answers coming in are great around different subjective situations.

• Is Akka a good solution for a concurrent pipeline/workflow problem?

  - by herpylderp

  Disclaimer: I am brand new to Akka and the concept of Actors/Event-Driven Architectures in general. I have to implement a fairly complex problem where users can configure a "concurrent pipeline": Pipeline: consists of 1+ Stages; all Stages execute sequentially Stage: consists of 1+ Tasks; all Tasks execute in parallel Task: essentially a Java Runnable As you can see above, a Task is a Runnable that does some unit of work. Tasks are organized into Stages, which execute their Tasks in parallel. Stages are organized into the Pipeline, which executes its Stages sequentially. Hence if a user specifies the following Pipeline: CrossTheRoadSafelyPipeline Stage 1: Look Left Task 1: Turn your head to the left and look for cars Task 2: Listen for cars Stage 2: Look right Task 1: Turn your head to the right and look for cars Task 2: Listen for cars Then, Stage 1 will execute, and then Stage 2 will execute. However, while each Stage is executing, it's individual Tasks are executing in parallel/at the same time. In reality Pipelines will become very complicated, and with hundreds of Stages, dozens of Tasks per Stage (again, executing at the same time). To implement this Pipeline I can only think of several solutions: ESB/Apache Camel Guava Event Bus Java 5 Concurrency Actors/Akka Camel doesn't seem right because its core competency is integration not synchrony and orchestration across worker threads. Guava is great, but this doesn't really feel like a subscriber/publisher-type of problem. And Java 5 Concurrency (ExecutorService, etc.) just feels too low-level and painful. So I ask: is Akka a strong candidate for this type of problem? If so, how? If not, then why, and what is a good candidate?

• Bash: Quotes getting stripped when a command is passed as argument to a function

  - by Shoaibi

  I am trying to implement a dry run kind of mechanism for my script and facing the issue of quotes getting stripped off when a command is passed as an argument to a function and resulting in unexpected behavior. dry_run () { echo "$@" #printf '%q ' "$@" if [ "$DRY_RUN" ]; then return 0 fi "$@" } email_admin() { echo " Emailing admin" dry_run su - $target_username -c "cd $GIT_WORK_TREE && git log -1 -p|mail -s '$mail_subject' $admin_email" echo " Emailed" } Output is: su - webuser1 -c cd /home/webuser1/public_html && git log -1 -p|mail -s 'Git deployment on webuser1' [email protected] Expected: su - webuser1 -c "cd /home/webuser1/public_html && git log -1 -p|mail -s 'Git deployment on webuser1' [email protected]" With printf enabled instead of echo: su - webuser1 -c cd\ /home/webuser1/public_html\ \&\&\ git\ log\ -1\ -p\|mail\ -s\ \'Git\ deployment\ on\ webuser1\'\ [email protected] Result: su: invalid option -- 1 That shouldn't be the case if quotes remained where they were inserted. I have also tried using "eval", not much difference. If i remove the dry_run call in email_admin and then run script, it work great.

• Squid url rewrites https>>http

  - by bobfran

  I'm exploring some uses with Squid proxy 2.7 and I have seen a good number of examples for url rewrites that take urls such as: http: //somesitename.com and then the rewriter can change the url to: https: //somesitename.com And those examples work great. What I'm wondering though, is if its possible to do the reverse with a squid url rewriter. that is, to go from https: //somesitename.com to http: //somesitename.com ? Simply trying to edit the script file that handles the rewrites doesn't seem to do the trick. So I was wondering if there are some certain things I have to configure squid to do first, if its even possible to do what I am asking. I have my browser manually set up to have squid as a proxy for all requests and I can see https requests showing up in my squid access.log file (via the CONNECT method).

• Is it worth moving from Microsoft tech to Linux, NodeJS & other open source frameworks to save money for a start-up?

  - by dormisher

  I am currently getting involved in a startup, I am the only developer involved at the moment, and the other guys are leaving all the tech decisions up to me at the moment. For my day job I work at a software house that uses Microsoft tech on a day to day basis, we utilise .NET, SqlServer, Windows Server etc. However, I realise that as a startup we need to keep costs down, and after having a brief look at the cost of hosting for Windows I was shocked to see some of the prices for a dedicated server. The cheapest I found was £100 a month. Also if the business needs to scale in the future and we end up needing multiple servers, we could end up shelling out £10's of £000's a year in SQL Server / Windows Server licenses etc. I then had a quick look at the price of Linux hosting for a dedicated server and saw the price was waaaaaay lower than windows hosting. One place was offering a machine with 2 cores for less than £20 a month. This got me thinking maybe the way to go is open source on Linux. As I write a lot of Javascript at work (I'm working on a single page backbone app at the moment), I thought maybe NodeJS and a web framework like Express would be cool to use. I then thought that instead of using SQL why not use an open source NoSQL database like MongoDB, which has great support on NodeJS? My only concern is that some of the work the application is going to do is going to be dynamically building images and various other image related stuff, i.e. stuff that is quite CPU heavy - so I'm thinking of maybe writing anything CPU heavy in C++ and consuming it as a module in Node. That's the background - but basically is Linux a good match for: Hosting a NodeJS/Express site? Compiling C++ node modules? Using a NoSQL DB like MongoDB? And is it a good idea to move to these unfamiliar technologies to save money?

• Recoomend company to take care or webserver and wordpress management?

  - by javipas

  I'm interested in setting up a professional WordPress site but I'd like to explore the pssibilities to leave the management of the webserver and even WordPress' management to a company that guarantees great availability, performance of the site (load times, security) and even SEO. My site is currently running on other platform but I plan on a migration on the next 4 weeks. I've done this usually, but I'd like to focus on the content, so I don't have to mess with webserver/mysql/php configs in order to get nice performance. Is there some (maybe hosting) company that is dedicated to this? Would it be better to hire a sysadmin with experience in those matters?

• Consultations with ATG Development at OpenWorld 2014

  - by Steven Chan (Oracle Development)

  Our OpenWorld 2014 San Francisco conference is about six weeks away.  We have a great lineup of sessions this year.  Our EBS Applications Technology track sessions are listed here, and we'll have a more-detailed article about those soon. One of the advantages of attending OpenWorld is that you can meet face-to-face with senior staff in ATG Development.  You can use these meetings to discusss your questions, requirements, plans, and deployment architectures with us. There are several options for doing this: At general sessions: collar the speaker of your choice after his or her presentation. At the Meet The Experts sessions:  these are first-come first-served round-table discussions Setting up private meetings via your Oracle account manager The last option is best if you have lots of in-depth questions or confidential details about your implementation that cannot be discussed in front of other customers.  Many of this blog's experts, including me, will be attending OpenWorld this year.  If you'd like to meet with us privately, please contact your Oracle account manager to arrange that as soon as possible.  My calendar, in particular, is already starting to fill up.  It is often completely full by the time OpenWorld starts. See you there!

• Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

  - by Johnnylight

  After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?

• Messaging with KnockoutJs

  - by Aligned

  MVVM Light has Messaging that helps keep View Models decoupled, isolated, and keep the separation of concerns, while allowing them to communicate with each other. This is a very helpful feature. One View Model can send off a message and if anyone is listening for it, they will react, otherwise nothing will happen. I now want to do the same with KnockoutJs View Models. Here are some links on how to do this: http://stackoverflow.com/questions/9892124/whats-the-best-way-of-linking-synchronising-view-models-in-knockout http://www.knockmeout.net/2012/05/using-ko-native-pubsub.html ~ this is a great article describing the ko.subscribable type. http://jsfiddle.net/rniemeyer/z7KgM/ ~ shows how to do the subscription https://github.com/rniemeyer/knockout-postbox will be used to help with the PubSub (described in the blog post above) through the Nuget package. http://jsfiddle.net/rniemeyer/mg3hj/ of knockout-postbox   Implementation: Use syncWith for two-way synchronization. MainVM: self.selectedElement= ko.observable().syncWith (“selectedElement”); ElementListComponentVM example: self.selectedElement= ko.observable().syncWith(“selectedElement”); ko.selectedElement.subscribe(function(){ // do something with the seletion change }); ElementVMTwo: self.selectedElement= ko.observable().syncWith (“selectedElement”); // subscribe example ko.postbox.subscribe(“changeMessage”, function(newValue){ }); // or use subscribeTo this.visible = ko.observable().subscribeTo("section", function(newValue) { // do something here }); · Use ko.toJS to avoid both sides having the same reference (see the blog post). · unsubscribeFrom should be called when the dialog is hidden or closed · Use publishOn to automatically send out messages when an observable changes o ko.observable().publishOn(“section”);

• What is the R Language?

  - by TATWORTH

  I encountered the R Language recently with O'Reilly books and while from the context I knew it was a language for dealing with statistics, doing a web search for the support web site was futile. However I have now located the web site and it is at http://www.r-project.org/R is a free language available for a number of platforms including windows. CRAN mirrors are available at a number of locations worldwide.Here is the official description:"R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS."

• Javascript widgets: do links count as SEO backlinks? [closed]

  - by j0nes

  Possible Duplicate: How good is it for SEO if you have a widget that lives on other sites? On my website I offer an option to let users embed information from my site with some kind of "homepage widget". If a user wants to embed it in his website, he basically has to add one line of Javascript to his HTML files like this: <script src="http://mysite.com/myscript.php?some_options_here"></script> Inside the widget, I export some content from my website and of course create a link back to my website. This is done in Javascript with document.write. document.writeln("My great exported content"); document.writeln('<a href="http://mysite.com?ref=widget>Check mysite.com</a>'); I have Google Analytics set up to track whether the links in there get clicked, and they do. Now I am asking myself if Google recognizes these links as valid backlinks from the embedding domain. I know that Googlebot can parse and execute Javascript, but I have not found any references whether these links also count as "normal" backlinks.

• How To Export/Import a Website in IIS 7.x

  - by Tray Harrison

  IIS 6 had a great feature called ‘Save Configuration to a File’ which would allow you to easily export a website’s configuration, to be later used to import either on the same server or another box.  This came in handy anytime you wanted to duplicate a site in order to do some testing without impacting the existing application.  So naturally, Microsoft decided to do away with this feature in IIS 7. The process to export/import a site is still fairly simple, though not as obvious as it was in previous versions.  Here are the steps: 1. Open a command prompt and navigate to C:\Windows\System32\inetsrv and run the following command: appcmd list site /name:<sitename> /config /xml > C:\output.xml So if you were wanting to export a website named EAC, you would run the following: If you’ll be setting up another copy of the site on the same server, you’ll now need to edit the output.xml file before importing it.  This is necessary in order to avoid conflicts such as bindings, Site ID, etc.  To do this, edit the XML and change the values.  Go ahead and make a copy of the home directory, and rename it to whatever folder name you specified in the output – /EAC2 in this example.  If you decide to change the app pool, make sure you go ahead and create the new app pool as well. Once these edits have been made, we are now ready to import the site.  To do that run: appcmd add sites /in < c:\output.xml So for our example it would look like this: That’s it.  You should now see your site listed when opening up Inet Manager.  If for some reason the site fails to start, that’s probably because you forgot to create the new app pool or there is a problem with one of the other parameters you changed.  Look at the System log to identify any issues like this.

• backup, sync and search files over internet and intranet

  - by Cawas

  There are many online backup options out there. Dropbox, Sugarsync, Mozy, Carbonite, Jungledisk and my favorite so far, Crashplan. Some of them allow searching, all of them sync with their online servers, none of those (or many many others I didn't listed here) have what I want. I'm _not_ looking for an online backup service in here. Sure, some people might say "use rsync", "linux" and/or "set up apache" and so on... But that's just too much for maintenance, if it's even viable of building up. It needs to be simple. So, anyone knows of a really good solution out there? Picture mostly Google Desktop Search (or quick search) awesome searching, mixed with Crashplan Desktop, which is able to do everything by itself, and something like Dropbox's file versioning, along with dropbox the ability to seamless sync over intranet and internet like crashplan, switching between them when needed. I bet there's nothing like this yet, but well, I'm not sure. It would be great!

• RESTful applications logic and cross resource operations

  - by Gaz_Edge

  I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

• Microsoft Lowers Cloud Barrier To Entry

  - by Herve Roggero

  Once in a while, the technology stack changes enough to create a disturbance in the IT industry. Microsoft did just that today and has officially closed the gap with its #1 competitor: Amazon. What is remarkable is that Microsoft is no longer an alternative to Amazon, it is becoming a clear leader in that space. Some of the new features include official support for durable Virtual Machines with high availability (cross-geographic replication), free WebSites to try Azure, MySQL database at no charge, a new distributed low-latency cache feature, Linux support, support with existing VPN hardware for seamless on-premise integration, a new partner ecosystem and much, much more. Amazon had an edge against Windows Azure in the IaaS (Infrastructure as a Service) space, until now. With the latest release from Microsoft Azure, the gap has been filled. In fact, it seems Amazon may now have a gap to fill… This is great news to everyone; it seems that cloud offerings are becoming more standardized with the more mature cloud providers, and the management stack and quality of service of each cloud provider is increasingly becoming the differentiator. With today’s announcements, it is becoming clear that cloud providers are pushing hard to increase their service footprint and lowering typical barriers to entry such as support for open-source operating systems, free trial offers, higher availability, faster deployment times and simpler enterprise integration.

• Make Exchange 2007 use the correct SSL certificate

  - by Neil

  I have an SBS 2008 server contososerver.contosodomain.local which is externally accessible with the domain remote.contoso.com and an SSL certificate for the external domain which we installed using the SBS 2008 wizard. This works great for OWA because IIS serves the remote.contoso.com certificate. I also want to turn on external POP3/IMAP4/SMTP however when I try, I get served the internal certificate that SBS generated automatically (using its internal CA) which has the alternate names remote.contoso.com, contososerver.contosodomain.local and contososerver. I tried removing this certificate from Exchange but it won't let me because it needs it for its internal receive connector. So how do I tell Exchange 2007 to use the real certificate for external POP3/IMAP4/SMTP?

• What could be wrong with my CD drive and how do you fix it?

  - by Jamie

  My CD drive hasn't worked in about 8 months. I was burning CDs in a hurry and pulled it out because it was taking too long (probably an average amount of time). Im running a laptop (Toshiba Satellite A505-6965) that uses a slot drive. Now my computer doesn't accept CDs. It used to pull them in but it doesn't anymore. Ive heard it make odd noises a few times but thats it. The slot is these spongey things and Ive managed to peek into the drive with a flashlight and theres nothing in the way, really. Could someone explain the mechanics of what happened and if it would be possible to fix it? If itd be possible to fix it through Linux that would be great since I keep getting the BSOD (0x0000007B) and am going to try reinstalling Windows 7. But I can't really do that since I don't have a USB drive larger than 2 GB (Windows is about 4 GB) so Im relying on Linux ATM.

• Necessary Infrastructure for large project with many components communicating through IPCs

  - by jluzwick

  I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

• JEditorPane on Steroids with Nashorn

  - by Geertjan

  Continuing from Embedded Nashorn in JEditorPane, here is the same JEditorPane on steroids with Nashorn, in the context of some kind of CMS backend system: Above, you see heavy reusage of NetBeans IDE editor infrastructure. Parts of it are with thanks to Steven Yi, who has done some great research in this area. Code completion, right-click popup menu, line numbering, editor toolbar, find/replace features, block selection, comment/uncomment features, etc, etc, etc, all the rich editor features from NetBeans IDE are there, within a plain old JEditorPane. And everything is externally extensible, e.g., new actions can be registered by external modules into the right-click popup menu or the editor toolbar or the sidebar, etc. For example, here's code completion (Ctrl-Space): It even has the cool new feature where if you select a closing brace and the opening brace isn't in the visible area, a rectangular popup appears at the top of the editor, to show how the current piece of code begins: The only thing I am missing is code folding! I wish that would work too, still figuring it out. What's also cool is that this is a Maven project.

• Content delivery: Alternatives to SHOUTcast

  - by polemon

  I've been using Icecast and SHOUTcast for several years now, to deliver audio and Video content. I wonder what kind of alternatives do I have to those two, especially when streaming video. On the client side, what software can I choose from to stream to those servers live? Making the streams available with Flash would be great, but that's maybe another story. We're still using EdCast, which is kinda dead by now, Shoutcast DSP plugin is not an option, as this tends to crash, etc. Are there any alternatives to that, when livestreaming video? I'm using Liquidsoap for content generation, mixing, etc. It should work with Icecast, Liquidsoap and if possible SHOUTcast.

• MS Word 2007 Mail Merge fails on ZIP codes with leading Zeros (eg. 01234)

  - by Pretzel

  I have an Excel Spreadsheet with a ZIP code column. For some dumb reason the original spreadsheet I got had all the zip codes stored as numbers, so a ZIP code like 01234 was stored as 1234. Easy to fix with "Format Column" as "Special = ZIP Code". All values like 1234, show up as 01234. Great! When I import it into Word via Mail Merge (to print address labels), the ZIP codes on all the addresses starting with a leading zero (like 01234) revert to their old form (1234). How do I fix this?

• 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!

• Haproxy Slow Reload in DB Mode

  - by com

  Recently I started using great tool for load balancing - Haproxy. There is only one disturbing thing that I cannot figure out how to deal with it. We use haproxy for load balancing mysql traffic. When there is a lot of traffic and many connection it takes ages for haproxy to reload (~ 30 min), with less traffic it doest reload within 1 min. I do reload with: service haproxy reload Of course if I need to do an urgent change in configuration I expect haproxy to do reload very fast. Killing haproxy instances waiting for disconnection causes to disconnection of msyql connections. It looks like that I made mistake in settings of haproxy or in settings of application. If you know how to solve this please help me. Thanks!
