I tried to add comments to your code, essentially your error means you are not defining query in all the possible code paths. Your code is confusing, I would just force the user to login before accessing your mainpage instead of trying to have the mainpage login your user.

Your also storing plain-text passwords which is a very bad practice.

Ros_posible_python_mistake

Asked 2022-Jan-12 at 21:21

guys I am making basic run and stop program for ROS simulation and I found a problem. I don't know why, when the call back function runs the self.l_scan = scan_data -> updates like it should. But when the is_obstacle member function runs. The self.l_scan is empty. I have probably some spell mistake, but I tried to look for it like for hour and I can not find the mistake. The topic /scan is from Turtlebot and it runs like it should. I tried via echo.

Your issue is because you're immediately calling move after finishing the constructor; where you setup the subscriber. This means there is relatively 0 chance that any data has been received. Instead, you should be validating that you have enough data before trying to slice the list and other operations on the data; because these operations assume you do have data. Something like this:

You were very close with your use of STRFTIME. It will convert the value it gets to a datetime, but since you were using integer math, then it didn't get the fractional time.

ANSWER

Answered 2021-Oct-16 at 21:17

All three MFC functions for which you have shown the source code (COleDateTime::SetDateTime, COleDateTime::ConvertSystemTimeToVariantTime and AtlConvertSystemTimeToVariantTime) have – according to their declarations – the potential to throw exceptions (because they have no specification to the contrary, such as noexcept).

However, that doesn't mean that they will (or are even likely to). Digging a bit further into the MFC source code, the only place I can see, in those three functions, where an exception could be thrown is in the ATLENSURE(pVarDtTm!=NULL); line (in the third function).

The ATLENSURE macro is defined as follows:

IMU Client responce values are all zero when runing ROS services

Asked 2021-Sep-13 at 18:11

I create ROS services that pass the IMU sensors values from the Server to Client. Im able to build the package but some how the Client values are all zeros.

So I would like to create IMU ROS services. I have a Server(in my case is a microcontroller ESC32) that can obtain IMU reading and should pass to the Client (in my case is Raspberry PI 4B) the IMU data when requested for further processing.So I just need to pass the raw IMU data. This is my .srv file

ANSWER

Answered 2021-Sep-13 at 14:45

The server is just returning the values of req which in the above code is a default service message passed in from main(). You need to cache the IMU values when them come in on a topic(in the server code). Then when the service is called it needs to pulled from the last IMU value. Your server needs to include something like this:

I would heavily suggest checking out the ros wiki tutorials. They have a lot of info that can also save you some time. That being said, you would just set it up like any other service call. You will probably also have to create your own message that might look something like this:

how to measure the cost of context switching more precisely

Asked 2021-Sep-09 at 16:16

I am writing some code to roughly measure the cost of context switching. The basic idea is inside the textbook OSTEP. And based on the idea, I wrote some code as below:

ANSWER

Answered 2021-Sep-09 at 16:16

#define BILLION 1e9 //not 10e9
The code is OK. read() does not return 0 if there's no data in the pipe—it blocks.

That's why the ping pong you're doing effectively measures the cost of context switches (+IO overhead).

read() returns 0 for the read end of a pipe only when all OS-counted references (created via dup* functions or forking in conjuction with fd inheritance) to the corresponding write end are closed.
You're effectively measuring context switches + the pipe's IO overhead. You can measure approximate IO overhead of the pipe separately by adapting the code to use just one pipe on a >=2 core system (so there's almost no context switch per an io call) and making one process a permanent reader and the other a permanent writer (https://pastebin.com/cGDWFdgQ). I'm getting about 2*0.55µs overhead + about 5.5µs for the whole thing so about 4.4µs per context switch).

QUESTION

Check if all goroutines have finished without using wg.Wait()

Asked 2021-Aug-26 at 16:23

Let's say I have a function IsAPrimaryColour() which works by calling three other functions IsRed(), IsGreen() and IsBlue(). Since the three functions are quite independent of one another, they can run concurrently. The return conditions are:

If any of the three functions returns true, IsAPrimaryColour() should also return true. There is no need to wait for the other functions to finish. That is: IsPrimaryColour() is true if IsRed() is true OR IsGreen() is true OR IsBlue() is true
If all functions return false, IsAPrimaryColour() should also return false. That is: IsPrimaryColour() is false if IsRed() is false AND IsGreen() is false AND IsBlue() is false
If any of the three functions returns an error, IsAPrimaryColour() should also return the error. There is no need to wait for the other functions to finish, or to collect any other errors.

The thing I'm struggling with is how to exit the function if any other three functions return true, but also to wait for all three to finish if they all return false. If I use a sync.WaitGroup object, I will need to wait for all 3 go routines to finish before I can return from the calling function.

Therefore, I'm using a loop counter to keep track of how many times I have received a message on a channel and existing the program once I have received all 3 messages.

You don't have to block the main goroutine on the Wait, you could block something else, for example:
