• Linux reboot() system call: why it calls do_exit(0) after kernel_halt()?

  - by axeoth

  This is related to: http://stackoverflow.com/a/13413099/1284631 Now, the question is: Why the reboot() system call, when called with LINUX_REBOOT_CMD_HALT parameter (see here: http://lxr.linux.no/linux+v3.6.6/kernel/sys.c#L480) is calling do_exit(0) after having already called kernel_halt(), as calling kernel_halt() boils down to calling stop_this_cpu() (see here: http://lxr.linux.no/linux+v3.6.6/arch/x86/kernel/process.c#L519), as part of native_machine_halt() (see here: http://lxr.linux.no/linux+v3.6.6/arch/x86/kernel/reboot.c#L680). Or, it seems to me that stop_this_cpu() is never returning (it ends with an infinite loop). So, it is do_exit(0) called just in case that kernel_halt() doesn't do its job and it return? Why not panic() directly instead, then?

• What's void *userData exactly?

  - by mystify

  In a C function declaration, I have seen this parameter definition: void *userData so, what exactly is that? My guess: the void says it can be anything arbitrary, or even nothing. Almost similar to id of objective-c. It just allows to pass in whatever data structure you like. The star in front of userData says, that the argument must be passed in by reference. So when using this stuff in the function body, typically it must be casted and dereferenced. So if I pass in an pointer to SomeClass instance, I would get that like this: SomeClass *myObj = (SomeClass*)userData; In the case I had nothing special to pass along, I would provide NULL as argument. Are my assumptions correct? Or did I get something wrong?

• How to change FPU context in signal handler (C++/Linux)

  - by Henry Fané

  I wrote a signal handler to catch FPE errors. I need to continue execution even if this happens. I receive a ucontext_t as parameter, I can change the bad operand from 0 to another value but the FPU context is still bad and I run into an infinite loop ? Does someone already manupulate the ucontext_t structure on Linux ? I finally found a way to handle these situations by clearing the status flag of ucontext_t like this: ... const long int cFPUStatusFlag = 0x3F; aContext->uc_mcontext.fpregs->sw &= ~cFPUStatusFlag; ... 0x3F is negated to put 0 in the 6 bits of the status register of the FPU (x87). Doing this implies to check for FPE exceptions after calculation.

• What is XcvPort (used in OpenPrinter function)

  - by RiskX

  I'm usin the OpenPrinter function and the first parameter the function gets called "pPrinterName" and that's it's MSDN description: [in] Pointer to a null-terminated string that specifies the name of the printer or print server, the printer object, the XcvMonitor, or the XcvPort. For a printer object use: PrinterName,Job xxxx. For an XcvMonitor, use: ServerName,XcvMonitor MonitorName. For an XcvPort, use: ServerName,XcvPort PortName. Obviously I'm interested in the bold part. What exactly is XcvPort? I know it seems like a question of lazy person but I really couldn't find info abou this concept. If I would like to open a printer on port ABC I should write: "\\MySrever,XcvPort ABC"? Thank you for your answers!

• PHP Value Object auto create

  - by JonoB

  Assume that I have a class value object defined in php, where each variable in the class is defined. Something like: class UserVO { public $id; public $name; } I now have a function in another class, which is expecting an array ($data). function save_user($data) { //run code to save the user } How do I tell php that the $data parameter should be typed as a UserVO? I could then have code completion to do something like: $something = $data->id; //typed as UserVO.id $else = $data->name; //typed as UserVO.name I'm guessing something like the following, but this obviously doesnt work $my_var = $data as new userVO();

• Generating a random displacement on the unit sphere

  - by becko

  Given a unit vector n, I need to generate, as fast as possible, another random unit vector m. The deviation of m from n should be on the order of a positive parameter sigma, and the distribution of m on the unit sphere should be symmetrical around n. I have no specific requirements on the representation of unit vectors, so you can use spherical angles, Cartesian coordinates, or whatever turns out to be convenient. Also, there are no precise requirements on the probability distributions used, as long as it decays when m deviates more than sigma from n. I am working with gsl and C. I have come up with a somewhat convoluted method using Cartesian coordinates. I will post it later if it is useful, but I would like to see people's ideas.

• Can a rake task know about the other tasks in the invocation chain?

  - by andrewdotnich

  Rake (like make) is able to have many targets/tasks specified on invocation. Is it possible for a rake task to access the list of tasks the user invoked, in order to do its job? Scenario: Consider a Rake-based build tool. A help task would like to know what tasks were also specified in order to print their usage and halt the build process. The benefit of this as opposed to rake-style parameter passing are cleaner syntax (rake help build instead of rake help task=build) and chaining (rake help build run_tests would print usage for both).

• Dynamically update Font Size of application with a single trigger in WPF

  - by Sukan

  I have an application which has different font sizes for different controls say Button: 10, TextBlock : 12 etc. I want to give options to the user where he can select any one of the below say Normal , Small, Big, Bigger. Suppose one selects "small" I would want to decrease every distinct font size by 2. If "Big", I would want to increase every font size by 2. I hope we can do this using converter sending actual font size as parameter and render as per the selected choice if I am not wrong. What will be the best option. Sorry if my doubt is absurd or silly. Thank you.

• Do I have to use Stored Procedures to get query level security or can I still do this with Dynamic S

  - by Peter Smith

  I'm developing an application where I'm concerned about locking down access to the database. I know I can develop stored procedures (and with proper parameter checking) limit a database user to an exact set of queries to execute. It's imperative that no other queries other then the ones I created in the stored procedures be allowed to execute under that user. Ideally even if a hacker gained access to the database connection (which only accepts connections from certain computers) they would only be able to execute the predefined stored procedures. Must I choose stored procedures for this or can I use Dynamic Sql with these fine grain permissions?

• Run batch file when argument contains quotes and spaces (from .NET framework)

  - by turtle

  I have a bat file which sets some environment variables, and then executes a command on the command line. I want to replace the hard coded command with one passed in via a parameter. So: :: Set up the required environment SET some_var=a SET another_var=b CALL some.bat :: Now call the command passed into this batch file %1 The problem is that the command is complex, and doesn't escape cleanly. It looks like this: an.exe -p="path with spaces" -t="some text" -f="another path with spaces" I'm trying to call the .bat from a .NET framework app, using: Dim cmd as String = "the cmd" System.Diagnostics.Process.Start( thebat.exe, cmd ) but I can't seem to get the escapes to work correctly. Can someone tell me how the string cmd should be entetered to get the command passed into the bat file as an argument correctly?

• Nhibernate Complex Type binding

  - by user329983

  I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

• What should I read to improve my C++ style

  - by Victor Ronin

  I was developing for quite long time already on C/C++ (mostly C, which makes style poorer). So, I know how to use it. However, quite often I stuck with style decisions like: - should I return error code here, throw exceptions, return error through a parameter - should I have all this stuff in constructor or should I create separate init function for that. and so on. Any solutions WILL work. However, each of them has cons and pros, which I know and most importantly which I don't know. It would be very nice to read something regarding overall C++ development style, coding practices and so forth. What do you recommend?

• How to pass an asp.net control to a jQuery ajax call?

  - by Abe Miessler

  I have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a textbox called "tb_name") as one of the parameters, in addition to the "target" parameter i'm already passing? <script type="text/javascript"> $(document).ready(function() { $("a").click(function(event) { $.ajax({ type: "POST", url: "Default.aspx/Click", data: "{target:'" + event.target + "'}", contentType: "application/json; charset=utf-8", dataType: "json", error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); $("#myContent").html(xhr.statusText); //alert(xhr.responseText); }, success: function(msg) { alert(msg.d); } }); return false; }) }) </script>

• Interesting Row_Number() bug

  - by Joel Coehoorn

  I was playing with the Stack Exchange Data Explorer and ran this query: http://odata.stackexchange.com/stackoverflow/q/2828/rising-stars-top-50-users-ordered-on-rep-per-day Notice down in the results, rows 11 and 12 have the same value and so are mis-numbered, even though the row_number() function takes the same order by parameter as the query. I know the correct fix here is to specify an additional tie-breaker column in the order by clauses, but I'm more curious as to why/how the row_number() function returned different results on the same data? If it makes a difference anywhere, this runs on Azure.

• Identifying idle state on a windows machine

  - by SaM

  I know about the GetLastInputInfo method but that would only give me the duration since last user input - keyboard or mouse. If a user input was last received 10 minutes ago, that wouldn't mean the system has been idle for 10 minutes - scans, downloads, movies - lots of reasons. So how can we identify whether the system is truly idle or not? Does anyone know what Window's definition of "idle" is? Must be a combination of thresholds - like less than 5% cpu util, less than 3% disk util etc. - along with the user input parameter...anyone knows the exact definition?
