  • Upstart: best way for shutdown hook?

    - by Binarus
    Hi, since Ubuntu relies on upstart for some time now, I would like to use an upstart job to gracefully shutdown certain applications on system shutdown or reboot. It is essential that the system's shutdown or reboot is stalled until these applications are shut down. The applications will be started manually on occasion, and on system shutdown should automatically be ended by a script (which I already have). Since the applications can't be ended reliably without (nearly all) other services running, ending the applications has to be done before the rest of the shutdown begins. I think I can solve this by an upstart job which will be triggered on shutdown, but I am unsure which events I should use in which manner. So far, I have read the following (partly contradicting) statements: There is no general shutdown event in upstart Use a stanza like "start on starting shutdown" in the job definition Use a stanza like "start on runlevel [06S]" in the job definition Use a stanza like "start on starting runlevel [06S]" in the job definition Use a stanza like "start on stopping runlevel [!06S]" in the job definition From these recommendations, the following questions arise: Is there or is there not a general shutdown event in Ubuntu's upstart? What is the recommended way to implement a "shutdown hook"? When are the events runlevel [x] triggered; is this when having entered the runlevel or when entering the runlevel? Can we use something like "start on starting runlevel [x]" or "start on stopping runlevel [x]"? What would be the best solution for my problem? Thank you very much, Binarus

  • Tips for switching jobs and moving into web based programming?

    - by JerryC
    I graduated in 2006 with a computer science degree and got solid grades (3.5 overall 3.8 in my major) For the past 4.5 years I've been working as a Software Engineer doing primarily rich client development. Most of my experience is with Java, Swing and C++. I've done a lot of network programming and I have acquired some skill working & debugging in distributed environments. I would like to switch jobs and move into a role where I can get exposure to some new technologies and frameworks. I would like to move into a more web development role but I find my lack of web development experience is hurting me. 90% of the jobs I see advertised are looking for one of two skill sets: 1) Stereotypical server side Java web developer. Experience with Spring, Hibernate, J2EE, etc. 2) Stereotypical front end web developer. Experience with Javascript, jQuery, HTML5, GWT, CSS, etc I find most of these companies are looking really specifically for this experience and they are not willing to take on good programmers/ CS fundamental guys who lack experience with this stuff. I would love to get a job doing stuff like this, but have my skills become out of date and unmarketable? Any opinions on ways to sell myself to help get a new position?

  • Any Practical Alternative to the Signals + Slots model for GUI Programming?

    - by IntermediateHacker
    The majority of GUI Toolkits nowadays use the Signals + Slots model. It was Qt and GTK+, if I am not wrong, who pioneered it. You know, the widgets or graphical objects (sometimes even ones that aren't displayed) send signals to the main-loop handler. The main-loop handler then calls the events, callbacks or slots assigned for that widget / graphical object. There are usually default (and in most cases virtual) event-handlers already provided by the toolkit for handling all pre-defined signals, therefore, unlike previous designs where the developer had to write the entire main-loop and handler for each and every message himself (think WINAPI), the developer only has to worry about the signals he needs to implement new functionality on. Now this design is being used in most modern toolkits as far as I know. There are Qt, GTK+, FLTK etc. There is Java Swing. C# even has a language feature for it ( events and delegates ), and Windows Forms has been developed on this design. In fact, over the last decade, this design for GUI programming has become a kind of an unwritten standard. Since it increases productivity and provides greater abstraction. However, my question is: Is there any alternative design, that is parallel or practical for modern GUI programming? i.e Is the Signals + Slots design, the only practical one in town? Is it feasible to do GUI Programming with any other design? Are any modern (preferably successful and popular) GUI toolkits built on an alternative design?

  • Experience vs. versatility

    - by Florin Bombeanu
    Let's say a .NET programmer works at a company which provides software on demand, not as a product. The programmer works in WPF for a period of time and he/she invests lots of time in it. He/she get very good at WPF and Windows Forms and desktop development in general. But the company has to provide a web application now, so the developer has to learn MVC or Web Forms. He/she is not experienced in web development so he/she starts investing time in this new technology and in time they get good at it. But this time the company has to provide a Sharepoint solution, and so on. What is more important: Being very very good at a certain technology, Or be as versatile as possible knowing less in each technology but covering a greater area of expertise? Should the programmer keep studying and working in WPF until he/she reaches a guru level or is it a good thing that they had to learn other technologies as well? I agree with those of you who will say that when learning different technologies you will also learn things which are useful no matter the technology you're programming in. But eventually, when the programmer will want to change jobs, will it matter more that he/she knows some WPF, MVC or Sharepoint than the fact that he/she is insanely good at one of them? I would think the second one is more important since most companies are looking for a developer for a certain technology. I don't think there are many companies looking for technical know-it-all people. What do you think?

  • Inheriting projects - General Rules?

    - by pspahn
    This is an area of discussion I have long been curious about, but overall, I generally lack the experience to give myself an answer that I would fully trust. We've all been there, a new client shows up with a half-complete project they are looking to finish and launch. For whatever reason, they fired their previous developer, and it's now up to you to save the day. I am just finishing up a code review for a new client, and in my estimation is would be better to scrap what the previous developers built since and start from scratch. There's a ton of reasons why I am leaning toward this way, but it still makes me nervous since the client isn't going to want to hear "those last guys built you a big turd, and I can either polish it, or throw it in the trash". What are your general rules for accepting these projects? How do you determine whether it will be better to start from scratch or continue with the existing code base? What other extra steps might you take to help control client expectations, since the previous developer may have inflated those expectations beyond a reasonable level? Any other general advice?

  • One of my most frequently used commands

    - by Kevin Smith
    On a Linux or UNIX server this is one of my most frequently used commands. find . -name "*.htm" -exec grep -iH "alter session" {} \; It is an easy way to find a string you know is in a group of files, but don't know or can't remember which file it is in. For the example above, I knew that WebCenter Content sends a bunch of alter session commands to the database when it opens a new database connection. I wanted to find where these were defined and what all the alter session commands were. So, I ran these commands: cd /opt/oracle/middleware/Oracle_ECM1/ucm/idc/resources/core find . -name "*.htm" -exec grep -iH "alter session" {} \; And the results were: ./tables/query.htm: ALTER SESSION SET optimizer_mode = ?./tables/query.htm: ALTER SESSION SET NLS_LENGTH_SEMANTICS = ?./tables/query.htm: ALTER SESSION SET NLS_SORT = ?./tables/query.htm: ALTER SESSION SET NLS_COMP = ?./tables/query.htm: ALTER SESSION SET CURSOR_SHARING = ?./tables/query.htm: ALTER SESSION SET EVENTS '30579 trace name context forever, level 2'./tables/query.htm: ALTER SESSION SET NLS_DATE_FORMAT = ?./tables/query.htm: alter session set events '30579 trace name context forever, level 2' I could then go edit the query.htm file and find the include that contained all the ALTER SESSION commands.

  • Lessons From OpenId, Cardspace and Facebook Connect

    - by mark.wilcox
    (c) denise carbonell I think Johannes Ernst summarized pretty well what happened in a broad sense in regards to OpenId, Cardspace and Facebook Connect. However, I'm more interested in the lessons we can take away from this. First  - "Apple Lesson" - If user-centric identity is going to happen it's going to require not only technology but also a strong marketing campaign. I'm calling this the "Apple Lesson" because it's very similar to how Apple iPad saw success vs the tablet market. The iPad is not only a very good technology product but it was backed by a very good marketing plan. I know most people do not want to think about marketing here - but the fact is that nobody could really articulate why user-centric identity mattered in a way that the average person cared about. Second - "Facebook Lesson" - Facebook Connect solves a number of interesting problems that is easy for both consumer and service providers. For a consumer it's simple to log-in without any redirects. And while Facebook isn't perfect on privacy - no other major consumer-focused service on the Internet provides as much control about sharing identity information. From a developer perspective it is very easy to implement the SSO and fetch other identity information (if the user has given permission). This could only happen because a major company just decided to make a singular focus to make it happen. Third - "Developers Lesson" -  Facebook Social Graph API is by far the simplest API for accessing identity information which also is another reason why you're seeing such rapid growth in Facebook enabled Websites. By using a combination of URL and Javascript - the power a single HTML page now gives a developer writing Web applications is simply amazing. For example It doesn't get much simpler than this "http://api.facebook.com/mewilcox" for accessing identity. And while I can't yet share too much publicly about the specifics - the social graph API had a profound impact on me in designing our next generation APIs.  Posted via email from Virtual Identity Dialogue

  • Inheriting projects - General Rules? [closed]

    Possible Duplicate: When is a BIG Rewrite the answer? Software rewriting alternatives Are there any actual case studies on rewrites of software success/failure rates? When should you rewrite?

The competition is strong: roughly 18% of entries are accepted each year from more than 3,000 submissions. Review panels are made up of experts both internal and external to Oracle. Successful submissions often (but not exclusively) focus on customer successes, how-tos, or best practices. http://www.oracle.com/openworld/call-for-papers/information/index.html What is in it for you? Recognition, for one thing. Accepted sessions are publicized in the content catalog, which goes live in mid-June, and sessions given by external speakers often prove the most popular. Plus, accepted speakers get a complimentary pass to Oracle OpenWorld with access to all sessions and networking events- that could save you up to $2,595! Be sure designate your session for inclusion in the correct track by selecting  “APPLICATIONS: Product Lifecycle Management from the Primary Track drop down menu. Looking forward to seeing you at this year's OpenWorld!

  • .NET Reflector Pro T-shirt contest - and the winner is...

    - by Laila
    Three weeks ago, I kicked off a T-shirt design contest. We've been eagerly poring over the results and today, it's finally announcement time! Although many of you raced to design some great t-shirts for us, we ended up with a clear winner who came up with a nice design and an original slogan that accurately represents what .NET Reflector Pro lets you do: decompile and debug C# and VB.NET code. So, the winner is... Mandeep Sangha! Mandeep sent us the following awesome design via the Twitter account, mss_10: We liked the combination of detective and superhero elements through the magnifying glass and the slogan. Batman (possibly the most eminent of detective-superheroes?) would be proud to wear this under his suit. Mandeep will become the happy owner of a free copy of .NET Reflector Pro and an exciting box of Red Gate goodies... as well as a copy of their very own t-shirt once it's been brought to life by our printing shop! The t-shirts will bear the name of their designer, and will be made available at .NET developer events around the world, such as conferences, tradeshows and user group events. Congratulations, Mandeep! We'll be in touch to sort out the details of your prizes. But that wasn't the only great design we received. We chose three runners-up as well: Sam Beauvois: http://twitpic.com/1vvsi9 Sherwin Rice: http://www.greenwaytechno.com/img/tee-1.png Mathieu Grétry: http://blog.section9.be/public/tshirt_reflector_01.png Thanks to you all for taking part in the contest. You'll all receive a free license for .NET Reflector Pro! We'll get in touch with you individually through twitter, so that we can get you your prizes. Keep an eye out for this T-shirt - it'll soon be making its way to an event near you!

  • Spotlight on an ACE: Edwin Biemond

    - by jeckels
    Edwin Biemond is an active member of the ACE community, having worked with Oracle's development tooling and database technologies since 1997. Since then, Edwin has become an expert in many of Oracle's middleware technologies as well, including WebLogic and SOA. In fact, Edwin has become so prolfic that he was named the Java Developer of the Year in 2009. Edwin hails from the Netherlands, where he is an architect at the company Amis, and is also a co-author of the OSB Development Cookbook. He's a proven expert in ADF, JSF, messaging (Edifact / ebXML), Enterprise Service Bus, web services and tuning of application servers and databases. Recently, Edwin posted a blog on the road map of WebLogic 12c, going over salient features and what the future looks like for Fusion Middleware and the Application Server areas - it's well worth a read, so give it a look. A snippet: WebLogic 12.1.3 will be the first version for many FMW 12c products like Oracle SOA Suite 12c and probably come in one big jar. 12.1.3 & 12.1.4 will add extra features and improvements to Elastic JMS & Dynamic Clusters. Elastic JMS in 12.1.3 will support Server Migration so you can’t lose any JMS messages. In 12.1.4, Dynamic Clusters will have support for auto-scaling based on thresholds based on user-defined metrics. WebLogic 12.1.4 will also have an API to control the Dynamic Clusters, this way we can easily program when to stop, start or remove nodes from a dynamic cluster. Further, Edwin is hosting a session on getting your FMW environment up and running in less than 10 minutes using popular tooling to configure and manage the many FMW components you have in your technology stack. Register now for this virtual developer day to see more. We thank Edwin for his commitment to being an ACE, his work on his blog, his social media publishing and his overall commitment to helping other technologists be even more successful with Oracle products. Follow Edwin on his blog, Twitter, Facebook, LinkedIn, or read his ACE Profile

  • As an indie game dev, what processes are the best for soliciting feedback on my design/spec/idea? [closed]

    - by Jess Telford
    Background I have worked in a professional environment where the process usually goes like the following: Brain storm idea Solidify the game mechanics / design Iterate on design/idea to create a more solid experience Spec out the details of the design/idea Build it Step 3. is generally done with the stakeholders of the game (developers, designers, investors, publishers, etc) to reach an 'agreement' which meets the goals of all involved. Due to this process involving a series of often opposing and unique view points, creative solutions can surface through discussion / iteration. This is backed up by a process for collating the changes / new ideas, as well as structured time for discussion. As a (now) indie developer, I have to play the role of all the stakeholders (developers, designers, investors, publishers, etc), and often find myself too close to the idea / design to do more than minor changes, which I feel to be local maxima when it comes to the best result (I'm looking for the global maxima, of course). I have read that ideas / game designs / unique mechanics are merely multipliers of execution, and that keeping them secret is just silly. In sharing the idea with others outside the realm of my own thinking, I hope to replicate the influence other stakeholders have. I am struggling with the collation of changes / new ideas, and any kind of structured method of receiving feedback. My question: As an indie game developer, how and where can I share my ideas/designs to receive meaningful / constructive feedback? How can I successfully collate the feedback into a new iteration of the design? Are there any specialized websites, etc?

  • My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

    - by Dominic Bou-Samra
    So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

  • Where is the line drawn with domain names which include a trademark?

    - by Thomas Clayson
    A search on google for "iphone developer" turns up loads of websites which have "iphone" in them, a trademarked name by Apple. So I'm led to believe that having a domain such as iphonedeveloper.com is ok? Well, you're still using Apple's trademark, but it would be hard to brand yourself otherwise. You're an IPHONE DEVELOPER... right? Well, what if I want to provide a website where users pay to get a list of the best offers from Ebay? I might have a domain like ebaydeals.com (I don't... i'm just speculating!). Now I've heard that places like Ebay are really hot on the trigger and fire out emails to people who register domains like that straight away. But whats the difference? In both cases I'm making money from the trademark, effectively, so is it just down to how lenient the company who owns the trademark is? Or are there rules? Is there a specific "line" you don't cross? Thanks

  • Improve Customer Experience with Real-Time Scheduling

    - by ruth.donohue
    Recently, my husband rearranged his busy work schedule so that he could stay home an entire afternoon to wait for the alarm company to reset the password to our alarm system, only to discover at the end of the afternoon that the field service rep wasn’t going to be able to make the appointment after all. And, the company asked him to reschedule and block off time for another afternoon. Needless to say, my husband wasn’t happy with that experience. Unfortunately, customer experiences like this happen every day. As a business, you can’t afford these types of encounters. It’s too easy for your customers to turn to one of your competitors once they’ve reached the point of frustration. Customer experience and customer loyalty are more important than ever. So how can you prevent something like this from occurring? With the newly available Siebel Field Service Integration with Oracle Real-Time Scheduler, your service organization can: Create cost-optimized plans and schedules to improve operating efficiencies Deliver more accurate ETA’s and shorten appointment windows Minimize the impact of in-day events such as delays on site, sickness, poor weather conditions, and vehicle breakdowns Rather than requiring them to wait for an entire afternoon, imagine asking customers to be available for only an hour. And being able to commit to that time by working around unforeseen events and understanding the impact of delays or re-routings before they become customer issues. What would your customer experience and customer satisfaction be like then? Learn more about the Siebel Field Service Integration with Oracle Real-Time Scheduler: Register for and attend the upcoming webcast on Thursday, March 10th at 8:30 AM Pacific Time Read the press release, data sheet, and solution brief Visit the Siebel Field Service webpage

  • Links to C++ AMP and other content

    - by Daniel Moth
    A few links you may be interested in. This week was a big week for Microsoft with the unveiling of the developer story for Windows 8 Metro-style apps. The recorded sessions are available on channel9. Note that you can use C++ AMP in both Metro and desktop apps, and in fact even on Windows 7. Visual Studio 11 Developer Preview is now available. To download it, here is a link to a link plus context. As I previously shared, I was also speaking at BUILD on C++ AMP, and here is a direct link to that recording. Kate Gregory has started a book on C++ AMP and she has graciously shared the first 1-2 draft chapters for free online – get the link from her blog post which is also where you can leave her feedback. As Yossi Levanoni (the architect of C++ AMP), posted on our team blog, the C++ AMP article that he and I co-authored is now available at Dr Dobbs. Important reminder: Questions on C++ AMP should be posted at http://social.msdn.microsoft.com/Forums/en/parallelcppnative/threads Comments about this post by Daniel Moth welcome at the original blog.

  • Software design of a browser-based strategic MMO game

    - by Mehran
    I wonder if there are any known tested software designs for Travian-like browser-based strategic MMO games? I mean how would they implement the server of such games or what is stored in database and what is stored in RAM? Is the state of the world stored in one piece or is it distributed among a number of storage? Does anyone know a resource to study the problems and solutions of creating such games? [UPDATE] Suggested in comments, I'm going to give an example how would I design such a project. Even though I'm not sure if I'm proposing the right one. Having stored the world state in a MongoDB, I would implement an event collection in which all the changes to the world will register. Changes that are meant to happen in the future will come with an action date set to the future and those that are to be carried out immediately will be set to now. Having this datastore as the central point of the system, players will issue their actions as events inserted in datastore. At the other end of the system, I'll have a constant-running software taking out events out of the datastore which are due to be carried out and not done yet. Executing an event means apply some update on the world's state and thus the datastore. As scalable as this design sounds, I'm not sure if it will be worth implementing. For one, it is pointless to cache the datastore as most of updates happen once without any follow ups. For instance if you have the growth of resources in your game, you'll be updating the whole world state periodically in which case, having incorporated a cache, you are keeping the whole world in RAM (which most likely is impossible). So can someone come up with a better design?

  • Pushing complete notifications to client

    - by ton.yeung
    So with cqrs, we accept that consistency is eventual. However, that doesn't mean that the user has to continually poll, or that eventual means an update has to take more then 500ms to sync. For the sake of UX, we want to at least give the illusion of consistency, or if not possible, be as transparent as possible. With that in mind, I have this setup: angularjs web client, consumes webapi restful services, sends commands to nservicebus command handlers, saves to neventstore, dispatches events to nservicebus event handlers, sends message to signalr hub, sends notifications to angularjs web client so with that setup, theoretically some initiates a request the server validates the request sends out the necessary commands In the mean time the client gets a 200 response updates the view: working on it gets message sometime later: done, here's the updated data Here's where things get interesting, each command could spawn multiple events. Not sure if this is a serious no, no, or not, but that's how it is currently. For example, a new customer spawns CustomerIDCreated, CustomerNameUpdated, CustomerAddressUpdated, etc... Which event handler needs to notify the client? Should all of them in a progress bar style update?

  • Be aware of the difference between CURRENT_DATE and SYSDATE

    - by Kevin Smith
    I was running some queries in SQL Developer against the WebCenter Content (WCC) schema that included date fields such as dInDate. I was comparing the dates against CURRENT_DATE. I was not getting the expected results. I did some googlng and didn’t find a solution, but I did run across a reference to SYSDATE. I tried SYSDATE in my queries and got the expected results. I did a TO_CHAR on the two date fields and found they returned different times. CURRENT_DATE returned the time from my laptop which was  in the EDT time zone. SYSDATE returned the time from the database server which happened to be in the PDT time zone. I guess if both the database server and my laptop were in the same time zone I would not have seen any problem. Here is the query I ran to display the two fields. select to_char(current_date,'DD-MON-YY HH:MI:SS'), to_char(sysdate,'DD-MON-YY HH:MI:SS') from dual; As you can see from the screen shot from SQL Developer they definitely returned different times. I’m sure there is some command or setting you can use to prevent this problem, but for me the take away is to use SYSDATE in your queries when you want to do any date comparison.

  • 1136: Incorrect number of arguments. Expected 0 AS3 Flash CS5.5 [on hold]

    how do I solve this error? I've been trying to get the answer online but have not been successful. I'm trying to learn As3 for flash so I decided to try making a preloader for a game.

  • What is the best type of c# timer to use with an Unity game that uses many timers simultaneously?

    - by Kyle Seidlitz
    I am developing a stand-alone 3d game in Unity that will have anywhere from 1 to 200 timers running simultaneously. For this game timer durations will range from 5 minutes to 4 days. There will not be any countdown displays or any UI for the timers. An object will be selected, a menu choice will then be selected, and the timer will start. Several events will occur at different intervals during the duration of the timer. The events will be confined to changing the material of the selected object, and calling a 1 second sound effect like a chime or a bell. If the user wants to save or end the game before all the timers are done, the start of the still running timers is to be saved to an XML file such that when the game is started again, any still running timers will have a calculation done to see if the timer is then done, where the game will change the materials appropriately. I am still trying to figure out what type of timer to use, and see also if there are any suggestions for saving and calculating times over several days. What class(es) of timers should I use? Are there any special issues I should look out for in terms of performance?
