            geom_isopycnal in ggoce returning error when used as standalone layer
            Asked 2022-Mar-20 at 21:03

            I would like to draw temperature salinity diagrams with isopycnals. I've been trying to use the ggoce::geom_isopycnal layer for ggplot2 but encounter an error when using it as a standalone layer, i.e using it with a data frame containing CTD data in the ggplot instead of using a ctd object created by the package oce. I was not able to find why the assert_has_lonlat() internal function of geom_isopycnal is returning this error when I did not specify any latitude or longitude in the call.

            According to the docs you need to add a ref_longitude and ref_latitude if eos is set to "gsw", as it is by default. You could set these to 0 without affecting the plot.

            The need for two tokens in .NET 6 Parallel.ForEachAsync?
            Asked 2021-Dec-01 at 22:16

            I was experimenting with how to break out of a ForEachAsync loop. break doesn't work, but I can call Cancel on the CancellationTokenSource. The signature for ForEachAsync has two tokens - one as a stand-alone argument and one in the Func body signature.

            I took note that when cts.Cancel() is called, both the token and t variables have IsCancellationRequested set to true. So, my question is: what is the purpose for the two separate token arguments? Is there a distinction worth noting?

            ...

            ANSWER

            Answered 2021-Dec-01 at 22:16

            Token passed to the body of the method invoked by ForEachAsync is a different one and comes from a internal CancellationTokenSource which will be canceled:

            So the purpose of cancellationToken CancellationToken argument passed to the Parallel.ForEachAsync is to support cancellation by caller and the one passed to the asynchronous delegate invoked by it - to support cancelation both by external (i.e. caller) and internal sources (see the P.S.).

            P.S.

            Also note that usually it is a good idea to pass and check the token state in your methods (i.e. await someConditionAsync(t) with corresponding implementation inside) since CancelationToken is used for so called cooperative cancelation.

            How to buffer and batch REST get queries with asp.net web API 2 (using TPL/Reactive)?
            Asked 2021-Nov-18 at 23:08

            I am runnning a public front facing api that hardly scale for now. This API is built upon Asp.Net web API 2 (.Net 4.7.2). This

            The problem that I have is that from this entry point the service have to make multiple calls to others internal services exposing their Rest interface. We have made some optimisation :

            • to make all those call asynchronous (async/await).
            • All the services (public facing one as well as internal) are load balanced and we have put in place 4 servers with hight memory ram/cpu (64 gb, 8cpu each)

            But when we have sudden burst of load , or when we make some stress tests we see that we have a pain to scale up : the response time start to increase and we could not achieve more than 150 req/s and average of response is 2.5 sec while all the time seem to been spend in the network latency wainting each internal service to respond.... So I was thinking if it was possible to buffer a bunch of requests and make a batch call to the internal apis to get the details to combine and then answer the callers.

            My idea would be to have a special kind of static httpClient with an async method that would bufferize the calls and will make a request when either there is a special count of calls bufferized or when a limit of few ms have elapsed : that way when we are under load our API could make few network calls and be more responsive... I know that somes are also using a mom/bus for that like Kafka for example , but it seems to me that going this way will only let us have eaven more paralell calls to handle but no real gain on the speed.. (I may be wrong on that)

            To illustrate what I have in mind :

            Do you think that this could be done using Reactive (for observe either the delay spent, or the count of messages bufferized)/TPL Dataflow (in order to fill a block and then make a batch call) ? I have this idea in mind but I do not know if it is a good idea, and how to make it work...

            Answered 2020-Nov-20 at 21:03

            After messing with this all day I finally figured out the missing piece.

            First, some quick notes on the original question (already touched on in the updates):

            • To do RSA signatures with PSS padding ("PS256") you will need a third-party library, because the OpenSSL functions in PHP don't support this. A common recommendation is phpseclib
            • The 32 magic bytes I had to add to the key were only a quirk of PHP's OpenSSL functions and don't need to be utilized with phpseclib

            With that said, my final problem (with the signature being "invalid") was:

            JWT signatures are base64URL encoded, not base64 encoded

            I wasn't even aware there was an RFC specification for base64URL encoding. It turns out you just replace every + with a - and every / with an _. So instead of:

            This isn't a leak. You are reading uninitialized memory. As @PaulMcKenzie says in the comments, time is not standard C++, rather it is a GCC extension that comes from C99.

            You could use memset to ensure that time is initialized. Alternatively, you could use std::vector, for instance
