            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:



            Answered 2021-Jun-15 at 23:55

            I haven't come across such a ConcurrentCounter library, but 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:

            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:



            Answered 2021-Jun-14 at 19:18

            According to the Go memory model:


            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.



            webforms all children performing async postback even when updatemode set to conditional
            Asked 2021-Jun-15 at 07:07

            I have an update panel with UpdateMode set to conditional, and childrenastriggers set to false, but all the controls in the panel are performing async postbacks...



            Answered 2021-Jun-15 at 04:47

            AsyncPostBackTrigger only sets controls that are outside of the panel.

            Controls on the page outside of an update panel can refresh an UpdatePanel control by defining them as triggers. Triggers are defined by using the AsyncPostBackTrigger element.

            Controls that postback will always postback. I think the ChildrenAsTriggers="false" won't stop the postbacks - it will just stop the content from updating.



            TokenAware policy Cassandra and several node in one query
            Asked 2021-Jun-15 at 06:07

            What happens if our query contains several tokens that finally there on different nodes? Are possible that the client runs multiple queries Sync or Async on nodes?




            Answered 2021-Jun-15 at 04:46

            For Sample 1, just query for single partition and merge results at the client end. This will be much faster. Datastax driver has token aware policy but it will only work when query refers to single partition.

            You can refer this link.

            For Sample 2, it is an anti pattern query and you cannot expect the client to do all the work for you. If you want to read complete table then you can use spark. Datastax provides spark-cassandra-connector which can provide somewhat same functionality which you have given. Here you can find description of spark-cassandra-connector.



            Golang Concurrency Code Review of Codewalk
            Asked 2021-Jun-15 at 06:03

            I'm trying to understand best practices for Golang concurrency. I read O'Reilly's book on Go's concurrency and then came back to the Golang Codewalks, specifically this example:


            This is the code I was hoping to review with you in order to learn a little bit more about Go. My first impression is that this code is breaking some best practices. This is of course my (very) unexperienced opinion and I wanted to discuss and gain some insight on the process. This isn't about who's right or wrong, please be nice, I just want to share my views and get some feedback on them. Maybe this discussion will help other people see why I'm wrong and teach them something.

            I'm fully aware that the purpose of this code is to teach beginners, not to be perfect code.

            Issue 1 - No Goroutine cleanup logic



            Answered 2021-Jun-15 at 02:48
            1. It is the main method, so there is no need to cleanup. When main returns, the program exits. If this wasn't the main, then you would be correct.

            2. There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.

            3. Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.

            To pass in a map[interface{}]interface{}, it will need to be defined as such.

            You can convert a map[string]string to a map[interface{}]interface{} using something like the following:



            Error: "Driver [default] not supported." in laravel 8
            Asked 2021-Jun-14 at 23:09

            I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:



            Answered 2021-Jun-12 at 01:50

            Your problem is that you have set SESSION_CONNECTION=session, but your SESSION_DRIVER=default, so you have to use SESSION_DRIVER=database in your .env. See the config/session.php:



            Move Google Contacts from One Group to Another

            I am trying to write a Google Script that I can run regularly to move contacts added to a custom group by a third party tool and move them to My Contacts so they sync on iOS.

            I am able to write a script to do it with a single contact as a test:



            Answered 2021-Jun-14 at 16:34


            addContact(contact) accepts a single contact, so you would need to use for loop to add the contacts one by one.



            pg_wal folder on standby node not removing files (postgresql-11)
            Asked 2021-Jun-14 at 15:00

            I have master-slave (primary-standby) streaming replication set up on 2 physical nodes. Although the replication is working correctly and walsender and walreceiver both work fine, the files in the pg_wal folder on the slave node are not getting removed. This is a problem I have been facing every time I try to bring the slave node back after a crash. Here are the details of the problem:

            postgresql.conf on master and slave/standby node



            Answered 2021-Jun-14 at 15:00

            You didn't describe omitting pg_replslot during your rsync, as the docs recommend. If you didn't omit it, then now your replica has a replication slot which is a clone of the one on the master. But if nothing ever connects to that slot on the replica and advances the cutoff, then the WAL never gets released to recycling. To fix you just need to shutdown the replica, remove that directory, restart it, (and wait for the next restart point to finish).

            Do they need to go to wal_archive folder on the disk just like they go to wal_archive folder on the master node?

            No, that is optional not necessary. It is set by archive_mode = always if you want it to happen.
