  • pretty print makefiles

    - by wickedchicken
    The linux kernel (and various other projects including git) have very nice makefiles that hide the giant cc calls into nice little acronyms. For example: gcc -O2 -o cool.o cool.c -llib gcc -O2 -o neat.o neat.c -llib would become: CC cool.c CC neat.c Which is really nice if you have a project with a large number of files and long compiler flags. I recall that this had to do with suppressing the default output and making a custom one. How do you do it?

  • Which's the best way to protect primary key on ASP.NET MVC?

    - by Junior Mayhé
    I'm creating a ASP.NET MVC website and I was wandering which techniques do you guys use to protect primary key on these mvc urls. Actually ASP.NET MVC generates this syntax for its urls: /Controller/Action/Id Last week I was trying to encrypt it using SHA-1 Encryption, but this encrypter generates some special symbols like + (plus), / (slash), and other annoying chars which difficult the decryption. Perhaps creating a custom encryption should solve the problem. But I wanna here from you guys, do you have some ideas to protect mvc urls?

  • Cables for building a computer

    - by Faken
    I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

  • Confusing .gitignore syntax

    - by tmslnz
    I was reading http://www.kernel.org/pub/software/scm/git/docs/gitignore.html and the 6 points used to explain the ignore patterns seem to be describing a custom variant of a glob search syntax. I am more familiar with Mercurial, which allows to explicitly ignore via glob or regex patterns, no questions asked. Is there anything similar functionality in Git? Can anyone point me to some more exhaustive reference than the Git man page? Best, t

  • What is the difference between moveBackward: and moveLeft: when using NSResponder -interpretKeyEvent

    - by nciagra
    I'm implementing a custom text box using -interpretKeyEvents: and am trying to figure out what the difference is between moveBackward: vs moveLeft: and moveForward: vs moveRight:. moveLeft: is bound to the left arrow and moveBackward: is bound to Ctrl + B. The documentation describes them almost identically and they seem to behave identically in practice. I'm assuming this is just a holdover from Vim? Does anyone know what the real difference is? Should moveBackward: just call my moveLeft: implementation? Thanks a lot, Nick

  • Forcing a transaction to rollback on validation errors in Seam

    - by Chris Williams
    Quick version: We're looking for a way to force a transaction to rollback when specific situations occur during the execution of a method on a backing bean but we'd like the rollback to happen without having to show the user a generic 500 error page. Instead, we'd like the user to see the form she just submitted and a FacesMessage that indicates what the problem was. Long version: We've got a few backing beans that use components to perform a few related operations in the database (using JPA/Hibernate). During the process, an error can occur after some of the database operations have happened. This could be for a few different reasons but for this question, let's assume there's been a validation error that is detected after some DB writes have happened that weren't detectible before the writes occurred. When this happens, we'd like to make sure all of the db changes up to this point will be rolled back. Seam can deal with this because if you throw a RuntimeException out of the current FacesRequest, Seam will rollback the current transaction. The problem with this is that the user is shown a generic error page. In our case, we'd actually like the user to be shown the page she was on with a descriptive message about what went wrong, and have the opportunity to correct the bad input that caused the problem. The solution we've come up with is to throw an Exception from the component that discovers the validation problem with the annotation: @ApplicationException( rollback = true ) Then our backing bean can catch this exception, assume the component that threw it has published the appropriate FacesMessage, and simply return null to take the user back to the input page with the error displayed. The ApplicationException annotation tells Seam to rollback the transaction and we're not showing the user a generic error page. This worked well for the first place we used it that happened to only be doing inserts. The second place we tried to use it, we have to delete something during the process. In this second case, everything works if there's no validation error. If a validation error does happen, the rollback Exception is thrown and the transaction is marked for rollback. Even if no database modifications have happened to be rolled back, when the user fixes the bad data and re-submits the page, we're getting: java.lang.IllegalArgumentException: Removing a detached instance The detached instance is lazily loaded from another object (there's a many to one relationship). That parent object is loaded when the backing bean is instantiated. Because the transaction was rolled back after the validation error, the object is now detached. Our next step was to change this page from conversation scope to page scope. When we did this, Seam can't even render the page after the validation error because our page has to hit the DB to render and the transaction has been marked for rollback. So my question is: how are other people dealing with handling errors cleanly and properly managing transactions at the same time? Better yet, I'd love to be able to use everything we have now if someone can spot something I'm doing wrong that would be relatively easy to fix. I've read the Seam Framework article on Unified error page and exception handling but this is geared more towards more generic errors your application might encounter.

  • Position of builtInZoomControls in WebView and MapView

    - by Mathias Lin
    I noticed that the position of the builtInZoomControls in WebView (bottom, horizontal right) is not consistent with the default position in the MapView (bottom, horizontal center). 1) Why is that not consistent? (Probably a question to be asked to Google) 2) Is there a way to horizontal center the builtInZoomControls of the WebView without applying custom Zoom controls? Or is that the only way?

  • CSS Calendar Display

    - by Steven
    I created my own custom date picker consisting of an ASP TextBox, Button, and Calendar complete with CSS styles, javascript code, and event handling vb code. I want to use this date picker multiple times on my form. I know the wrong way to do this would be to copy all the code and just adjust each name accordingly. How can I put those controls, styles, and code into a single entity?

  • Run SQL scripts on windows mobile installer

    - by Guillermo Vasconcelos
    Hi, We are working on a Windows Mobile 6.5 application. The application is already installed in some devices, and we need to distribute a new version with changes in the database schema (we added a few tables). Is there a way to make a "patch" windows mobile installer that will replace the application and update the embedded SQL database with some scripts? In a normal windows installer we would create a custom action in the installation process to apply the changes in the database, but I'm not sure how to do that for Windows Mobile Thanks.

Even if yes, I couldn't find how to convert .resx to .resources to feed it to al.exe. And if no, where to put the .resx. and how to name it?

  • Spring to understand properties in YAML

    - by litius
    Did Spring abandon YAML to use as an alternative to .properties / .xml because of: [Spring Developer]: ...YAML was considered, but we thought that counting whitespace significant was a support nightmare in the making... [reference from spring forum] I am confident YAML makes a lot of sense for properties, and I am using it currently on the project, but have difficulties to inject properties in a <property name="productName" value="${client.product.name}" /> fashion. Anything I am missing, or I should create a custom YamlPropertyPlaceholderConfigurer ? Thank you, /Anatoly
