  • A Trip to the Moon (Le Voyage dans la Lune) [Super Retro Classic Sci-Fi Video]

    - by Asian Angel
    If you are into retro sci-fi movies, then you will definitely want to have a look at this French classic from 1902. This silent movie is only 10.5 minutes long, but is well worth watching and makes for a fun romp through the early days of sci-fi. From YouTube: A Trip to the Moon (French: Le Voyage dans la lune) is a 1902 French black and white silent science fiction film. It is loosely based on two popular novels of the time: From the Earth to the Moon by Jules Verne and The First Men in the Moon by H. G. Wells. The film was written and directed by Georges Melies, assisted by his brother Gaston. The film runs 14 minutes if projected at 16 frames per second, which was the standard frame rate at the time the film was produced. It was extremely popular at the time of its release and is the best-known of the hundreds of fantasy films made by Melies. A Trip to the Moon is the first science fiction film, and utilizes innovative animation and special effects, including the iconic shot of the rocketship landing in the Moon’s eye.

  • Distribute Sort Sample Service

    - by kaleidoscope
    How it works? Using the front-end of the service, a user can specify a size in MB for the input data set to sort. Algorithm CreateAndSplit The CreateAndSplit task generates the input data and stores them as 10 blobs in the utility storage. The URLs to these blobs are packaged as Separate work items and written to the queue. · Separate The Separate task reads the blobs with the random numbers created in the CreateAndSplit task and places the random numbers into buckets. The interval of the numbers that go into one bucket is chosen so that the expected amount of numbers (assuming a uniform distribution of the numbers in the original data set) is around 100 kB. Each bucket is represented as a blob container in utility storage. Whenever there are 10 blobs in one bucket (i.e., the placement in this bucket is complete because we had 10 original splits), the separate task will generate a new Sort task and write the task into the queue. · Sort The Sort task merges all blobs in a single bucket and sorts them using a standard sort algorithm. The result is stored as a blob in utility storage. · Concat The concat task merges the results of all Sort tasks into a single blob. This blob can be downloaded as a text file using this Web page. As the resulting file is presented in text format, the size of the file is likely to be larger than the specified input file. Anish

  • Different Flavors of Leases Back On

    - by Theresa Hickman
    Given the continued interest regarding the proposed changes to Lease Accounting, I decided to write another entry on this controversial topic with colorful commentary from our resident accounting expert, Seamus Moran. Background (A History Lesson) Back in 1976, the FASB issued FAS 13, “Accounting for Leases” that permitted leases to be either an operating lease or capital (finance) lease. In substance, operating leases are a form of off-balance sheet financing. According to Seamus, operating leases date back to the launch of the Boeing 707 in the 1950s.  Because the aircraft was so much more expensive than previous aircrafts, the industry came up with the operating lease concept to accommodate these jet liners that dominated air transport.  How it worked was the bank would buy the plane and lease it to the airline.  Because the bank never controlled or flew the plane, they never placed the asset on their balance sheet, and because the airline never owned the plane, they didn’t place it on their balance sheet either. They simply treated the monthly lease payments as rental expenses on the P&L.   August 2010 Original Lease Accounting Changes In August 2010, FASB and IASB decided to overhaul lease accounting as part of their joint commitment “to insure that investors and other users of financial statements are provided useful, transparent, and complete information about leasing transactions in the financial statements.”  Some say that the current lease accounting standards are broken because it keeps assets off the balance sheet, hidden from investors’ view. The original proposal abolished operating leases and only permitted capital leases where all leases would be recorded on the balance sheet as assets and liabilities. The asset side would reflect the right to use the asset for the leased term, and the liability side would reflect the obligation to make lease payments.   Why Companies Were Freaking Out According to the SEC, the financial impact of the aforementioned lease changes was estimated to add more than $1.3 trillion of operating lease obligations to corporate balance sheets. Many companies in various industries, especially retail, are concerned because the changes are significant and will impact existing leases with no grandfather clause for existing operating leases. Of course, the banks and airlines I mentioned earlier really hate this because neither wants to report the airplane (now costing around $60 M) as an asset. Regular companies were concerned that they would have to report routine short term leases of real estate or equipment as fixed assets, even though they were really just longer term rentals.  One company we spoke to leased roadside billboards, and really did not consider them to be fixed assets in any way. Obviously, these changes would have had a profound and lasting effect on a company’s financial and real estate strategies and significantly impact its financial statements.  Financial statements would show higher depreciation and interest expense with significantly higher total assets and debt. In terms of financial metrics, they’re negatively impacted. It would raise a company’s debt-to-capital ratio to reflect the higher debt compared to equity, it would negatively impact their return-on-assets because now companies will appear more asset intensive, and it will decrease EPS, lowering shareholder ROI. Feb. 2011 Recent Update The comment period on leases closed in December 2010. The FASB and the IASB have met several times since then and published their initial responses to the input they received from the various interested parties.  They are “redeliberating” the principles involved in Lease Accounting.  Some of the issues they are looking at include: The core definition of a lease.  This will articulate principles on what is a lease and what is “not-a-lease.” One theory or supposition is that they might define a lease as the transfer of certain but not all major ownership attributes for a certain period of time.  So a year’s lease of an aircraft might be a “lease,” but a year’s lease of half a floor in an office building would be “not-a-lease.”  The ownership attributes transferred from the core owner to the user are different; the airline must maintain, paint, and do whatever it needs to do on the aircraft. However, the office renter will have strictly limited rights in respect to the rented space. The differences between a lease contract and service contract.  Even if they call them “leases” for the purpose of commercial law, a service contract might not be accounted for as a lease. The accounting to be done by the lessee.  They would define when the bank or landlord would retain the asset on their balance sheet, and perhaps by implication, when the lessor would not need to include the asset on theirs.  So if the finance house keeps the airplane or office on their balance sheet, the tenant doesn’t need to.  I’m not sure that I can draw the opposite conclusion where the finance house doesn’t report but the tenant must. The difference, if any, between a financing lease and other leases, and the implications to the accounting. The present value calculation when renewable terms exist. They have reduced the circumstances in which one must look at the renewable terms of a lease in calculating the present value.  In most circumstances, you will use the lease term rather than the potential renewable term. Their latest discussion this past week with the contents of the discussion was not available at the time of me writing this entry.  For more details, the results of the discussions are posted on both the FASB and the IASB websites. Implied Software Changes Whatever the final rules turn out to be, all ERP systems, such as Oracle E-Business Suite, PeopleSoft Enterprise, JD Edwards, and Oracle Hyperion will need to change their software to accommodate the new rules. The following lists some changes that might have to be made to accounting software depending on what the final standards will be in June 2011: Lease tracking may require modifications with tracking of additional lease details that might require a centralized repository to maintain Accounting may need to be modified as there are many changes to how capital leases and the new “other than finance” leases are accounted for both on the lessee and lessor side.  For example, valuation, amortization, and disclosure will be considerably different requiring different types of data to be captured. Companies may need to modify their chart of accounts depending on how they want to track leases, which could then impact financial reporting and consolidation Business processes may require changes which could then impact internal controls Software applications may need to perform more advanced computations on leases Reports and KPIs may need to reflect new operating metrics Hold Onto Your Seats           Before you redo all your lease agreements and call your software vendors asking when the changes to the software will be made, remember that the rules are not finalized yet, and from appearances, will not reflect the proposals in the exposure draft.  Not only are there objections to putting the operating lease assets on anyone’s balance sheet, there are lots of objections to subjectivity and the data required for the valuation.  According to Seamus, there is huge opposition from New York bankers, the airlines, the EU, the Communist Party of China (since it impacts their exporting business), and Republicans (hearing complaints from small and large businesses). Even if everyone can agree on the proposed changes, 2013 might be the earliest that companies would need to change how they report leases. The Boards will finish their deliberations in April, May or June 2011.  As we’ve seen with other Exposure Drafts, if the changes are minor and the principles met the General Acceptance consensus criteria, the Standard could be finalized at that time.  However, if substantial changes are made, a fresh exposure draft, comment period, and review period might be involved, too. Seamus added an interesting perspective. Even if the proposed changes do pass, don’t you think our customers, such as Boeing, GE Capital, United Airlines, etc. will be clever enough to come up with a new kind of financing arrangement that complies with the new accounting? How about the large retail customers, such as Best Buy and Macerich? Don’t you think they might simply cut deals around retail locations with new contracts that prevent their leases from being capital leases? Instead of blindly adapting the software to meet the principles outlined in the final standard, our software needs to accommodate how businesses will respond to the new rules. We cannot know our customers’ responses until the rules are finalized. Oracle is aware of the potential changes and is staying abreast of the developments through our domain expertise staff, our relationship with customers, our market awareness, and, of course, our relationships with the Big 4. This is part of our normal process with respect to worldwide regulatory compliance. Oracle products have been IFRS and GAAP compliant for years and we will continue to maintain those standards going forward.

  • How to talk a client out of a Flash website?

    - by bunglestink
    I have recently been doing a bunch of web side projects through word of mouth recommendations only. Although I am much more a of a programmer than a designer by any means, my design skills are not terrible, and do not hate dealing with UI like many programmers. As a result, I find myself lured into a bunch of side projects where aside from a minimal back end for content administration, most of the programming is on front end interfaces (read javascript/css). By far the biggest frustration I have had is convincing clients that they do not want Flash. Aside the fact that I really do not enjoy Flash "development", there are many practical reasons why Flash is not desirable (lack of compatibility across devices, decreased client accessibility, plug-in requirements, increased development time, etc.). Instead of just flat out telling the clients "I will not build you a flash website", I would much rather use tactics to convince/explain to them that this is not what they actually want, ie: meet their requirements any better than standard html/css/js and distract users from their content. What kind of first hand experience do others have with this? How do you explain to someone that javascript/css/AJAX is usually a better option for most websites? Why do people want to use Flash so bad to begin with? This question pertains to clients who do not have any technical reasons for wanting flash, but just want it because they think it makes pretty websites.

  • I want to build a Virtual Machine, are there any good references?

    - by Michael Stum
    I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

  • Is 12.10 ready from prime time?

    - by Mikey
    I recently installed 12.10 - dual boot using Wubi. I had numerous stability problems: many sporadic, unaccounted for system errors, software that was installed and then seemed to disappear from App Launcher, etc. Machine is new HP quad with 4 gig memory - wonderful piece of hardware - definitely no hardware problems there. I went back to 12.04 (installed from ISO image, not Wubi) and it's rock solid - never any issues at all. Is 12.10 not ready for prime time? Are there fixes-updates in the pipe? Should I get a DVD disc and install 12.10 from ISO instead of Wubi? New to Linux/Ubuntu after 20 years on MS/Windows and loving it - I develop in C++ and Python - maybe will try Lazarus since I know Delphi. Would like to use the latest and greatest Ubuntu but I will not sacrifice stabilty. Are there known problems with 12.10? Would using the standard install instead of Wubi help? Seems a lot of users are voting down this question - not sure why since other users have confirmed problems.

  • What are the advantages of Maven when it comes to single man, educational projects

    - by Leron
    I've spend a few hours playing around with Maven + reading some stuff on the apache official site and also a few random googled articles. By this I mean that I really tried to find the answers myself - both by reading and by doing things on my own. Also maybe worth to mention that I installed the m2e plugin so most of the time I've tried things out from Eclipse and not using the command line too much. However aside from the generated project that for example prevent me from using the default package I didn't see that much of a difference with the standard way I've created my projects before try Maven. In fact I've almost decided to skip Maven for now and move on to the other technology I wanted to learn more in-depth - Hibernate, but when I start with opening the official page the first thing I've read was the recommendation to use Hibernate with Maven. That get me confused and made me taking a step back and trying once more to find what I'm obviously missing right now. As it's said in the maven.apache.. site, the true strength of Maven is shown when you work on large projects with other people, but I lack the option to see how Maven is really used in this scenario, still i think that there are maybe advantages even when it comes to working with small projects alone, but I really have difficulties to point them out. So what do you think are the advantages of Maven when it's used for small projects writing from a single person. What are the things that I should be aware of and try to exploit (I mean features offered by Maven) that can come in handy in this situations?

  • Entity Object Based on PL/SQL

    - by Manoj Madhusoodanan
    This blog describes how to create a PL/SQL based Entity Object.Oracle application has number of APIs and each API will perform numerous number of tasks.We can create PL/SQL based EO which will directly invoke the PL/SQL stored procedure from the EO. Here I am demonstrating using a standard API FND_USER_PKG.CREATEUSER.This API has x_user_name and x_owner as mandatory parameter.My task is to create a user through OAF page which will accept User Name and Password. Following steps needs to be performed to achieve the above scenario. 1) Create FndUserEO as follows Include all the API parameters and WHO columns in the EO. Make UserName and EncryptedUserPassword ( Here I am not using Encrypted Password. The column name is same as table column so I am keeping the same) column as mandatory. Generate VO. 2) Edit FndUserEOImpl and add the following 3) Attach FndUserVO to AM 4) Create the UI 5) Deploy following files to middle tier and restart the server.  Entity Object: xxcust.oracle.apps.fnd.user.schema.server.FndUserEO.xml xxcust.oracle.apps.fnd.user.schema.server.FndUserEOImpl.java View Object: xxcust.oracle.apps.fnd.user.server.FndUserVO.xml xxcust.oracle.apps.fnd.user.server.FndUserVOImpl.javaUser Interface: xxcust.oracle.apps.fnd.user.webui.CreateFndUserCO.java xxcust.oracle.apps.fnd.user.webui.CreateFndUserPG.xmlYou can test by giving User Name and Password.

  • Handling changes to data types and entries in a database migration

    - by jandjorgensen
    I'm fully redesigning a site that indexes a number of articles with basic search functionality. The previous site was written about a decade ago, and I'm salvaging about 30,000 entries with data stored in less-than-ideal formats. While I'm moving from MSSQL to MySQL, I don't need to make any "live" changes, so this is not a production-level migration issue so much as a redesign. For instance, dates are stored the same as tags/subjects about the articles, but in strings as "YYYYMMDDd" (the lowercase d stands for "date" in the string). Essentially, before or after I move from the previous database format to a new one, I'm going to need to do a lot of replacement of individual entries. While I understand how to do operations with regular expressions in non-database issues, my database experience isn't robust enough to know the best way to handle this. What is the best (or standard) way to handle major changes like this? Is there an SQL operation I should be looking into? Please let me know if the problem isn't clear--I'm not entirely sure what kind of answer I'm looking for.

  • Old programmer disappeared. About to hire another programmer. How do I approach this?

    - by pocto
    After spending over one year working on a social network project for me using WordPress and BuddyPress, my programmer has disappeared, even though he got paid every single week, for the whole period. Yes, he's not dead as I used an email tracker to confirm and see he opens my emails, but he doesn't respond. It seems he got another job. I wonder why he just couldn't say so. And I even paid him an advance salary for work he hasn't done. The problem is that I never asked for full documentation for most of the functions he coded in. And there were MANY functions for this 1+ year period, and some of them have bugs that he still didn't fix. Now it seems all confusing. What's the first thing I should do now? How do I proceed? I guess the first thing to do will be to get another programmer, but I want to start on the right foot by having all the current code documented so that any programmer can work on all the functions without issues. Is that the first thing I should do? If yes, how do I go about it? What's the standard type of documentation required for something like this? Can I get a programmer that will just do the documentation for all the codes and fix the bugs or is documentation not really important? Also, do you think getting another "individual" programmer is better or get a company that has programmers working for them, so that if the programmer assigned to my project disappears, another can replace him, without my involvement? I feel this is the approach I should have taken in the beginning.

  • Can Near Field Communications (NFC) Benefit your Supply Chain?

    - by Stephen Slade
    Leading firms continue to leverage the latest tools and technologies to drive performance especially around minimizing transaction costs. With razor thin margins in manufacturing and distribution, the leading producers are resorting to Near Field Communications to gain efficiencies.  In this week’s CIO magazine (Apr1, 2012, pg.30, see http://www.cio.com)  Lauren Brousell talks of the things you need to know to make a more informed decision with NFC.  Sandy Shen of Gartner says NFC appeals because "it supports any services that requires data transfer and authentication' 1. NFC is Cheap and Easy - short range transmitting technology connecting smartphones to data transfer. 2. Adoption Seems Inevitable - more merchants will use NCF for payments in the futures. Wallets are becoming obsolete. 3. It's a Hot Potato for Enterprise - Business with credit card companies and cell phone providers are debating who handles the billing process. 4. It's in use Overseas. Japan uses FeliCa to pay by smartphone. In the US, billing agreements are causing territorial conflict. 5. Security Risks Come Standard. As people lose HH devices, security will be an ongoing concern. Credentials and timeout features and alleviate to some extent. My prediction: In 5 years, we won't have wallets in our pockets.  Our secure and all-powerful smart phones will be our electronic portable banks and execute the transaction for us based on our preferences and propensities and electronically execute the transaction for the supply chain.

  • 12.10 visual performance using nvidia driver

    - by user100485
    My fresh ubuntu 12.10 install is slow, not something extreme but dragging windows, switching workspaces and things like that are just slow and look horrible. it feels like the fps is dropping in a game. Doing some photoshop work in windows was even a relief! This effect gets worse if I connect my external monitor. My system is an intel pentium dual core T4500 with 4gb memory and a GeForce 8200M G/integrated/SSE2 graphics chip. Nothing fancy but should be able to run ok. My "experience" in ubuntu is set to standard. (MSI cr500 laptop) I've installed the nvidia drivers, tried current and experimental and the experimental drivers seem to perform a bit better but overall bad anyway. I set the mode to adaptive in the nvidia-settings tool and it goes to maximum setting directly and doesn't come back. Using htop I found out that compiz or the X server always use a few percent of my cpu, more than I think it should and the time consumed is 5:18 for compiz, 4:33 for /usr/bin/X and 2:41 for google chrome(about 30 tabs open so not too strange I think.) What can I do to increase the visual performance cause this makes me not want to use ubuntu in public!

  • How should I share variables between instances/classes?

    - by tesselode
    I'm making a game using LOVE, so everything is programmed in Lua. I've been experimenting with using classes and object orientation recently. I've found out that a nice system to use is having most of the game's code in different classes, and having a table of instances with all of the instances of any class in it. This way, I can go through every instance of every class and update and draw it by calling the same function. There is a problem, though. Let's say I have an instance of a player with variables for health and recharge time of a weapon. I also have a master instance which is responsible for drawing the HUD. How can I tell the master instance what the player's health is? Bad solutions: Assuming that the player instance will always have the same position in the table - that can be easily changed. Using global variables. Global variables are evil. Have the master instance outside of the instances table, and have the player set variables inside the master instance, which it then uses for HUD drawing. This is really bad because now I have to make a duplicate of every variable the master instance needs. What is the proper, standard way of sharing variables between instances? Do I need to change the way I keep track of instances?

  • Developing an internet-enabled application as a Kiosk on Windows 7

    - by maple_shaft
    I am finalizing development of a desktop Java application that communicates with an outside web server, and now I need to start seriously considering deployment. This application will run on a large touchscreen all-in-one workstation running Windows 7. It will be located in a public-area and thus must be LOCKED-DOWN Hanibal Lecter style. Early in the project nobody really concerned themselves with this fact just assuming that we can buy some magical software for Windows 7 that will automatically take care of all this, however I am finding now that this looks to be a LOT more complicated than my manager ever thought. I need to: - Lock down the standard hot-keys (ALT+TAB, ALT+CTRL+DEL, etc...) Prevent the user from opening ANY programs other than the kiosk application and its spawned executables Prevent the user from closing the application Start the kiosk application on startup (this can be done without kiosk software) Auto-login to Windows on reboot (Windows Updates, power failure, bratty kid pressing the power button, etc...) Administrator passcode escape sequence for routine maintenance by desktop support professionals. To my dismay I am having a really hard time finding software that contains the whole package and am finding numerous swaths of competing information on the best way to do this. I am not necessarily looking for free or open source software and am willing to pay for software that can help me achieve this. Have any of you ever wrote kiosk software before and if so what approaches have you taken to do this?

  • CLR 4.0: Corrupted State Exceptions

    - by Scott Dorman
    Corrupted state exceptions are designed to help you have fewer bugs in your code by making it harder to make common mistakes around exception handling. A very common pattern is code like this: public void FileSave(String name) { try { FileStream fs = new FileStream(name, FileMode.Create); } catch (Exception e) { MessageBox.Show("File Open Error"); throw new Exception(IOException); } The standard recommendation is not to catch System.Exception but rather catch the more specific exceptions (in this case, IOException). While this is a somewhat contrived example, what would happen if Exception were really an AccessViolationException or some other exception indicating that the process state has been corrupted? What you really want to do is get out fast before persistent data is corrupted or more work is lost. To help solve this problem and minimize the chance that you will catch exceptions like this, CLR 4.0 introduces Corrupted State Exceptions, which cannot be caught by normal catch statements. There are still places where you do want to catch these types of exceptions, particularly in your application’s “main” function or when you are loading add-ins.  There are also rare circumstances when you know code that throws an exception isn’t dangerous, such as when calling native code. In order to support these scenarios, a new HandleProcessCorruptedStateExceptions attribute has been added. This attribute is added to the function that catches these exceptions. There is also a process wide compatibility switch named legacyCorruptedStateExceptionsPolicy which when set to true will cause the code to operate under the older exception handling behavior.

  • Implementing a post-notification function to perform custom validation

    - by Alejandro Sosa
    Introduction Oracle Workflow Notification System can be extended to perform extra validation or processing via PLSQL procedures when the notification is being responded to. These PLSQL procedures are called post-notification functions since they are executed after a notification action such as Approve, Reject, Reassign or Request Information is performed. The standard signature for the post-notification function is     procedure <procedure_name> (itemtype  in varchar2,                                itemkey   in varchar2,                                actid     in varchar2,                                funcmode  in varchar2,                                resultout in out nocopy varchar2); Modes The post-notification function provides the parameter 'funcmode' which will have the following values: 'RESPOND', 'VALIDATE, and 'RUN' for a notification is responded to (Approve, Reject, etc) 'FORWARD' for a notification being forwarded to another user 'TRANSFER' for a notification being transferred to another user 'QUESTION' for a request of more information from one user to another 'QUESTION' for a response to a request of more information 'TIMEOUT' for a timed-out notification 'CANCEL' when the notification is being re-executed in a loop. Context Variables Oracle Workflow provides different context information that corresponds to the current notification being acted upon to the post-notification function. WF_ENGINE.context_nid - The notification ID  WF_ENGINE.context_new_role - The new role to which the action on the notification is directed WF_ENGINE.context_user_comment - Comments appended to the notification   WF_ENGINE.context_user - The user who is responsible for taking the action that updated the notification's state WF_ENGINE.context_recipient_role - The role currently designated as the recipient of the notification. This value may be the same as the value of WF_ENGINE.context_user variable, or it may be a group role of which the context user is a member. WF_ENGINE.context_original_recipient - The role that has ownership of and responsibility for the notification. This value may differ from the value of the WF_ENGINE.context_recipient_role variable if the notification has previously been reassigned.  Example Let us assume there is an EBS transaction that can only be approved by a certain people thus any attempt to transfer or delegate such notification should be allowed only to users SPIERSON or CBAKER. The way to implement this functionality would be as follows: Edit the corresponding workflow definition in Workflow Builder and open the notification. In the Function Name enter the name of the procedure where the custom code is handled, for instance, TEST_PACKAGE.Post_Notification In PLSQL create the corresponding package TEST_PACKAGE with a procedure named Post_Notification, as follows:     procedure Post_Notification (itemtype  in varchar2,                                  itemkey   in varchar2,                                  actid     in varchar2,                                  funcmode  in varchar2,                                  resultout in out nocopy varchar2) is     l_count number;     begin       if funcmode in ('TRANSFER','FORWARD') then         select count(1) into l_count         from WF_ROLES         where WF_ENGINE.context_new_role in ('SPIERSON','CBAKER');               --and/or any other conditions         if l_count<1 then           WF_CORE.TOKEN('ROLE', WF_ENGINE.context_new_role);           WF_CORE.RAISE('WFNTF_TRANSFER_FAIL');         end if;       end if;     end Post_Notification; Launch the workflow process with the changed notification and attempt to reassign or transfer it. When trying to reassign the notification to user CBROWN the screen would like like below: Check the Workflow API Reference Guide, section Post-Notification Functions, to see all the standard, seeded WF_ENGINE variables available for extending notifications processing.

  • SSIS Dashboard v0.4

    - by Davide Mauri
    Following the post on SSISDB script on Gist, I’ve been working on a HTML5 SSIS Dashboard, in order to have a nice looking, user friendly and, most of all, useful, SSIS Dashboard. Since this is a “spare-time” project, I’ve decided to develop it using Python since it’s THE data language (R aside), it’s a beautiful & powerful, well established and well documented and with a rich ecosystem around. Plus it has full support in Visual Studio, through the amazing Python Tools For Visual Studio plugin, I decided also to use Flask, a very good micro-framework to create websites, and use the SB Admin 2.0 Bootstrap admin template, since I’m all but a Web Designer. The result is here: https://github.com/yorek/ssis-dashboard and I can say I’m pretty satisfied with the work done so far (I’ve worked on it for probably less than 24 hours). Though there’s some features I’d like to add in t future (historical execution time, some charts, connection with AzureML to do prediction on expected execution times) it’s already usable. Of course I’ve tested it only on my development machine, so check twice before putting it in production but, give the fact that, virtually, there is not installation needed (you only need to install Python), and that all queries are based on standard SSISDB objects, I expect no big problems. If you want to test, contribute and/or give feedback please fell free to do it…I would really love to see this little project become a community project! Enjoy!

  • intel atom getting too hot

    - by user59565
    I own an Asus 1215N which is getting very hot Intel Atom 525D dual core ION 2 (geforce 220 + GMA 3150) 4 GB RAM Ubuntu 12.04 it hits 86 C at idle. Some times (at load or turned on 1 hour) it shuts down due to heat, in Windows 7 it runs idle at 49 C. I tried an acpi call to shut down the nVidia chip which is cooled together with the Atom chip. That didn't solve the problem. To check up to see if it really turned off I checked how much power the laptop consumed, it only went from using 1400 mW to 860 mW, no changes in heat. I also tried reapply the standard heat adhesive, the old heat adhesive made it run at 97 (it couldn't even put up a useful install of Ubuntu). This really annoys me, as Ubuntu is the OS of choice to me. Should I try compile the kernel? Is it true that compile for a P4 is the better choice to the atom, when compiling the kernel for this processor architecture? Now I tried compiling the kernel for atom. Now temperature is 83 C (think the drop has more to do with ambient temp than the customized kernel) help appreciated

  • Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)

    - by Stefan Armbruster
    My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device. Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001. Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches. Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work. When connecting the headset, /var/log/syslog shows: Aug 25 21:32:47 x230 bluetoothd[735]: Badly formated or unrecognized command: AT+CSRSF=1,1,1,1,1,7 Aug 25 21:32:49 x230 rtkit-daemon[1879]: Successfully made thread 17091 of process 14713 (n/a) owned by '1000' RT at priority 5.

  • Hidden web standards behind Google "custom searchEngines"?

    - by Hoàng Long
    Today while playing with Google Chrome Omnibox, I notice a strange behavior. I guess there's some "hidden" web standard behind it, but can't figure it out. Here's how to reproduce: Go to http://edition.cnn.com/ Use the search function at the higher right corner, Search a random keyword, for example: "abc" Close the tabs. Open a new tab, type until Chrome reminds you about http://edition.cnn.com/, then press "Tab" The Omnibox now shows "Search CNN.com"! And when you type "abc" and press Enter, it uses the CNN search function to do the job, not Google! I also tried it for several different sites. To some it won't work. But to some sites, like CNN, vnexpress.net, it works after I use the search function of that site once. I also learnt about chrome://settings/searchEngines (type it in your chrome box and you will see), and learnt about you can add custom search engine in chrome. But the question is, why Chrome can realize the search URL automatically to some pages, and not others? It's not because some site subscribe to Google service, because I can do the same method for my site (http://ledohoanglong.wordpress.com), and I'm sure that there's no subscription. So I guess there's a method to "expose" the search function of a site, so that Google Chrome can catch it (after I call the search function of that site once, of courses). Does anyone know about how it works behind the scene?
