QUESTION

Concurrent Counter Struct with Type Argument in Rust

Asked 2021-Jun-15 at 23:55

I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).

Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?

I thought that I could do this with generic type arguments:

ANSWER

Answered 2021-Jun-15 at 23:55

I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.

Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:

Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

How to thread a generator

Asked 2021-Jun-15 at 16:02

I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?

For example I'd guess it is possible to run the simplified code below in 11 seconds.

Send your data to separate processes. I used concurrent.futures because I like the simple interface.

XCUITest - interacting with notification from lock screen

Asked 2021-Jun-15 at 14:49

I am attempting to write a a UI test that taps on a delivered local notification after the device has been locked. I have been successful so far in tapping on a notification that was delivered on the springboard (when the device is already unlocked) but not from the lock screen. Does anyone know if this is possible?

Please note that this is different from questions such as this one, which merely hit the home button to leave the app under test and wait for the notification.

Here is the relevant portion of my test code:

I have similar issues, and I was able to resolve them by Adding a press lock Again. Here is the working code. I am using https://github.com/pterodactyl for Notifications. I wrote this code a couple of years back and still passing.

I do the same thing twice and able to validate notifications. Once the device is locked. You will see a black screen like it is turned off, and the second time when you will send the same code, it will turn on the device, and you can get notifications element for tests

// Lock the screen
XCUIDevice.shared.perform(NSSelectorFromString("pressLockButton"))
sleep(1)

// same command second time ,it will wake the screen
XCUIDevice.shared.perform(NSSelectorFromString("pressLockButton"))

How is this code snippet an example of incorrect synchronization?

Asked 2021-Jun-15 at 12:46

I am trying to understand the example with incorrect sync code from The Go Memory Model.

Double-checked locking is an attempt to avoid the overhead of synchronization. For example, the twoprint program might be incorrectly written as:

ANSWER

Answered 2021-Jun-14 at 19:18

According to the Go memory model:

https://golang.org/ref/mem

There are no guarantees that one goroutine will see the operations performed by another goroutine unless there is an explicit synchronization between the two using channels, mutex. etc.

In your example: the fact that a goroutines sees done=true does not imply it will see a set. This is only guaranteed if there is explicit synchronization between the goroutines.

The sync.Once probably offers such synchronization, so that's why you have not observed this behavior. There is still a memory race, and on a different platform with a different implementation of sync.Once, things may change.

How to properly use Executer In Room Android

Asked 2021-Jun-15 at 11:44

So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :

You need to quote the *: nodemon -e "*" src/server.js.

Unlike Windows' cmd, Linux shells expand wildcards (as you can see in the command actually run, above the error). In Windows it's up to the program you are calling to expand wildcards. Since that is what you want in case of nodemon, it worked "by chance" on Windows without escaping the asterisk because it doesn't have any special meaning to cmd, but in Linux it will get expanded and that's not what you want.
