  • how to souce a csh script in bash to set the enviroment

    - by Daniel
    We have oracle running on Solaris, and the shell is by default CSH. So the login script set the oracle_home,oracle_sid in csh also. But I don't like csh and want to use bash to do my work. So how to source the csh login script in bash? e.g, the following is what in the .cshrc file. And when use bash, I'd like use these variables. One way is to copy the variables again and use bash command, such as export ORACLE_SID=TEST. But doing so will let us to maintain two copy of the files. And when we change the database name, or upgrade the database, I need to maintian the bash login file seperately. It's nice to just use something like source .cshr in bash, but it doesn't work. setenv ORACLE_SID TEST setenv ORACLE_HOME /oracle/TEST/home/products/10204 setenv EPC_DISABLED TRUE setenv MANPATH /usr/local/man:/usr/share/man setenv EDITOR vi setenv LD_LIBRARY_PATH $ORACLE_HOME/lib:/usr/sfw/lib/64 setenv NLS_LANG AMERICAN_AMERICA.UTF8 setenv NLS_DATE_FORMAT "DD-MON-RR"

  • Video Synthesis - Making waves, patterns, gradients...

    - by Nathan
    I'm writing a program to generate some wild visuals. So far I can paint each pixel with a random blue value: for (y = 0; y < YMAX; y++) { for (x = 0; x < XMAX; x++) { b = rand() % 255; setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise, but I'm not sure where to start (Google isn't helping me much today), so it would be great if you could share anything you know on the subject or some links to related resources.

  • Paypal adaptive payment API call with C# .NET? Preferably with WebServices

    - by Phil
    Okay I might be entirely off track now but here goes: Our "webshop" offers two functions, buying a specific product and selling it back to us. Back-end handles if the user can sell or not. I've decided to use Paypal's adaptive payments for this one as it seems the way to go doing these kinds of transactions. I've never implemented any kind of shop so I'm totally green with this one. I only recently learned ASP.NET and have mainly developed games before moving to this kind of development. HTTP is still some level of magic to me hehe.. I might be confused but I think paypal offers a webservice with their adaptive payment API. My humble request: A nice soul who wants to share an example of implementing an adaptive payment API call with C# .NET. If they don't offer it as a webservice I'll probably find it as a custom .dll or something. Any tips and examples are highly appreciated! Thanks for reading

  • DRY programming dilemma

    - by fayer
    the situation is like this: im creating a Logger class that can write to a file but the write_to_file() function is in a helper class as a static function. i could call that function but then the Log class would be dependent to the helper class. isn't dependency bad? but if i can let it use a helper function then what is the point of having helper functions? what should one prioritize here: using helper functions and have to include this helper class everywhere (but the other 99 methods wont be useful) or just copy and paste into the Log class (but then if i have done this 100 times and then make a change i have to change in 100 places). share your thoughts and experience!

  • Is it worthwhile to implement observer pattern in PHP?

    - by Extrakun
    I have been meaning to make use of design pattern in PHP, such as the observer pattern, but that I have to recreate the observers' relationship each time the page is loaded pains me. As references are saved as a new concrete objects in session, there is no way to preserve relationships between subscribers and their observers unless you use a GUID or some other properties to form a lookup, and store that property instead. With the cost of recreating the relationships each time a page is loaded, is it worthwhile to use design patterns such as observers in PHP, compared to having a clean design? Any real-world experience to share?

  • MSSQL Efficiently dropping a group of rows with millions and millions of rows

    - by Net Citizen
    I recently asked this question: http://stackoverflow.com/questions/2519183/ms-sql-share-identity-seed-amongst-tables (Many people wondered why) I have the following layout of a table: Table: Stars starId bigint categoryId bigint starname varchar(200) But my problem is that I have millions and millions of rows. So when I want to delete stars from the table Stars it is too intense on MS SQL. I cannot use built in partitioning for 2005+ because I do not have an enterprise license. When I do delete though, I always delete a whole category Id at a time. I thought of doing a design like this: Table: Star_1 starId bigint CategoryId bigint constaint rock=1 starname varchar(200) Table: Star_2 starId bigint CategoryId bigint constaint rock=2 starname varchar(200) In this way I can delete a whole category and hence millions of rows in O(1) by doing a simple drop table. My question is, is it a problem to have thousands of tables in your MS SQL? The drop in O(1) is extremely desirable to me. Maybe there's a completely different solution I'm not thinking of?

  • Ideas on collaborating with small number of people

    - by Mark Szymanski
    Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

  • Need Users to Re-authenticate with NTLM

    - by Trey Carroll
    I'm NTLM (authenication="windows" in the web.config) with an asp.net mvc 2.0 site. Right now once a user logs in it keeps them logged in for weeks at a time. The use of the application is being opened up to users who share computers that use logged in service accounts. I need the site to reprompt each user for their AD credentials each time in order to handle these users. (Activity on the site must be linked to a uniquely identified user.) Thanks for any help that you can provide. Trey Carroll

I can share measurement data to other people.

  • How to handle BL cache for multiple web applications?

    - by Eran Betzalel
    I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application). I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.

  • T-SQL How To: Compare and List Duplicate Entries in a Table

    - by Dan7el
    SQL Server 2000. Single table has a list of users that includes a unique user ID and a non-unique user name. I want to search the table and list out any users that share the same non-unique user name. For example, my table looks like this: ID User Name Name == ========= ==== 0 parker Peter Parker 1 parker Mary Jane Parker 2 heroman Joseph (Joey) Carter Jones 3 thehulk Bruce Banner What I want to do is do a SELECT and have the result set be: ID User Name Name == ========= ==== 0 parker Peter Parker 1 parker Mary Jane Parker from my table. I'm not a T-SQL guru. I can do the basic joins and such, but I'm thinking there must be an elegant way of doing this. Barring elegance, there must be ANY way of doing this. I appreciate any methods that you can help me with on this topic. Thanks! ---Dan---

  • Which is the better approach in custom pages ?

    - by Mina Samy
    Hi all I want to create a custom new item page for sharepoint but there are two approached that I can use and I want to share your experience in determining which is better. The first: is to create a page in a library then create a C# library project to handle the events of the controls on the page. The second: is to define a feature of the content type of my list and specify the new item form to be my custom form, then create a website containing the custom form and put this site at the layouts folder. for me the first approach is fine but the problem is that a user may access the default sharepoint new item form which I don't want to happen. but I don't like the idea of placing the form in a library on the site. so which is better in your opinion ? thanks

  • Are government programming jobs good?

    - by Absolute0
    I am a passionate software developer and greatly enjoy programming. However I was recently contacted regarding a developer lead position for a government job at NYC for the fire department. The pay is pretty good, and I would assume the position has good job security and stability. But I am hesitant to even go for an interview as it seems like an exaggerated version of Office Space with a lot of Bureaucracy and mindless paper work. The description is as follows: The Lead Applications Developer, supporting the Programming Group, will be responsible for all phases of the system development life cycle including performing system analysis, requirements definition, database design, preparation of scopes of work, and development of project plans. Supervise programming staff and manage projects involving the design, implementation, maintenance, and enhancement of complex Oracle based user applications using Oracle Development tools. Applications will be deployed using Oracle Application Server utilizing programming languages such as JAVA, JSF, JSP, Oracle ADF, PL/SQL, and XML with J2EE and EJB technology. Anyone with previous government experience can share their two cents on this? Thank you.

  • JPA @TableGenerator shared between multiple entities

    - by Mauricio
    Hi Guys, I have a 'dog' Entitiy with an @Id and a @TableGenerator ... @TableGenerator(table = "seq", name = "dog_gen", pkColumnName = "seq_name", valueColumnName="seq_val") @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "dog_gen") private Long id; ... Is there a way to reuse the same table generator (dog_gen) in other entity? I want to keep the same id sequence in two independent Entities, say dog=1, dog=2, dog=3, cat=4, cat=5, dog=6 and so on... Both entities don't share a common superclass to implement some kind of inheritance with the id property. If I add the @GeneratedValue( generator="dog_gen") on my cat entity, omitting the @TableGenerator declaration throws an Exception saying it can't find the generator when starting the context. Caused by: org.hibernate.AnnotationException: Unknown Id.generator: dog_gen at org.hibernate.cfg.BinderHelper.makeIdGenerator(BinderHelper.java:413) at org.hibernate.cfg.AnnotationBinder.bindId(AnnotationBinder.java:1795) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1229) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:733) at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:498) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:277)

Say i have to work with two tables "Customer Master" and "Indian Customer" in ideal situation both tables are compleatly different, and are not interrelated in anyways. however they share the same database Content of "Customer Master": CustomerName (colomn): a, b, c, d, e Branchlocation (colomn): IN, AU, IN, IN, UK Content of "Indian Customer": customerID (colomn): 1, 2, 3 CustomerName (colomn): a, c, d customer details (colomn): details1, details, details . . . In Table "Indian Customer" i want to put a constraint so that the users entring data in this table should not be able to enter customers that dont exist in "Customer Master" or whose branch location is not IN. also the tables are in the same project but are not directly related.

  • Where can I find free WPF controls and control templates?

    - by Geoffrey Chetwood
    Duplicate: Where can I find free WPF controls and control templates? I am looking for some recommendations on good places to find libraries of controls/templates/styles for WPF. I know about the usual places like Infragistics, but it seems to me that there should be some kind of community effort by now to share nice, clean, well written controls for WPF controls. I am not big on the design side, and it would be nice to fill out my personal libraries with some nice examples from people who are better at design. Any ideas/recommendations?

  • Which open source social networking platform to use?

    - by vrao
    I want to build a highly secure social networking portal. Like other portals, subscriber users should be able to create a topic, discuss topic, share information about them, and have the ability for notifications/alerts. The added feature, I would like to have is to moderate users. Based on the topic of discussion, users will be asked automated questions and their responses will be processed to provide recommendations. I have no knowledge of social networking portal requirements. I will be coding alone and want to have something up and running in about six months. Which is the easiest open source platform that I should use to develop? I know some.net and sql, but I am open to use other platforms. Please give me your recommendations

  • Application Context in Rails

    - by Sean McMains
    Rails comes with a handy session hash into which we can cram stuff to our heart's content. I would, however, like something like ASP's application context, which instead of sharing data only within a single session, will share it with all sessions in the same application. I'm writing a simple dashboard app, and would like to pull data every 5 minutes, rather than every 5 minutes for each session. I could, of course, store the cache update times in a database, but so far haven't needed to set up a database for this app, and would love to avoid that dependency if possible. So, is there any way to get (or simulate) this sort of thing? If there's no way to do it without a database, is there any kind of "fake" database engine that comes with Rails, runs in memory, but doesn't bother persisting data between restarts?

  • Visual Studio - "attach to particular instance of the process" macro

    - by Steve
    I guess prety much everyone who does a lot of debugging have a handy macro in Visual Studio (with shortcut to it on a toolbar) which when called automatically attaches to a particular process (identified by name). it saves a lot of time rather than clicking "Debug" - "Attach to the process ...", but it only works if one is running a single instance of the process one wants to attach to. If theres is more than one instance of particular process in memory - the first one (with a smaller PID?) is being choose by debugger. Does anyone have a macro which shows a dialog (if more that 1 process with a specified name running) and lets developer to select to one he/she really wants to attach to. I guess the selection could be made based on a windwow caption text (which would be suffice in most of cases) and when the particular instance is selected macro passes the PID of the process to the Debugger object? If someone has that macro or knows how to write it - please share. Thanks.

  • zen of Python vs with statement - philosophical pondering

    - by NeuronQ
    I don't intend to simply waste your time, but: has it occurred to you too, while using Python's with statement that it really is contrary to the 5th line of "The Zen of Python" that goes "Flat is better than nested"? Can any enlightened Python guru share me some of their insights on this? (I always find that one more level of indentation pops up in my code every time I use with instead of f.close()... and it's not like I'm not gonna use try: ... finally: ... anyways and thus the benefits of with still elude me, even as I grow to like and understand Python more and more...)
