101 | A modern JS utility library

kandi X-RAY | 101 Summary
101 utils are made to work well with vanilla JS methods. 101 will only duplicate vanilla JS to provide Functional Programming paradigms, or if the method is not available in a widely supported JS version (currently ES5). Other libraries often duplicate a lot of ES5: forEach, map, reduce, filter, sort, and more.

QUESTION
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 23:55I 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:

I had to ask two questions to be able to solve it. If you are dealing with this kind of questions a lot, you are required to learn igraph
package which is primarily used for network analysis. There maybe a more simple way of doing it but for now I think it will do. Let's walk you through it:
QUESTION
I have to formulate SQL Query to display total success and failed device processing. Suppose User selects 2 devices and runs some process. Each Process which user triggers will spawn 4 jobs (1 devices has 2 jobs to run). Since here user select 2 devices so 4 records comes in db. Now based on ParentTaskId I need to display total successfull,failed jobs with total devices.
We count a job on a device as success only when both jobs(Type 1,Type 2) are success.
Note : If jobtype 1 fails , jobtype 2 will not trigger
...ANSWER
Answered 2021-Jun-15 at 15:47You can use two levels of aggregation -- the inner one to get the status per parent and device. For this, you can actually use min(taskStatus)
to get the status:

I am having problems restarting the emulator after turning it off. Restarting android studio - doesn't help. Restarting my computer helps. I also cannot find and [stop this process] through the task manager. So that I can not reboot. By the way, the error is displayed with a typo. Help. Who faced such a problem, how to solve it?

Answered 2021-Jun-15 at 14:21On Windows, the software that runs the Android Emulator is called "qemu-system-x86_64.exe".
Try to kill this software. You can use the built-in taskkill
utility from within the Command Prompt:
- Open the Command Prompt (Type in CMD into the Windows search)
- Enter:
taskkill /F /IM "qemu-system-x86_64.exe" /T

I want to filter a TableA, taking into account only those rows whose "TotalInvoice" field is within the minimum and maximum values expressed in a ViewB, based on month and year values and RepairShopId (the sample data only has one RepairShopId, but all the data has multiple IDs).
In the view I have minimum and maximum values for each business and each month and year.

Answered 2021-Jun-15 at 01:11The problem is that the kv

Keep class names capitalized to avoid syntax errors
I think your code will work if you change all your class names to meet that requirement.
