QUESTION
Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).
Same contracts (different addresses), same function call.

Here's the code I use to call them in my tests

QUESTION
I am having trouble tracking down documentation on this, so hoping someone knows as I am not able to get application insights to capture telemetry on starttrackevent and stopstrackevent across pages. This is an asp.net mvc application, so SPA is not in play here.
I am worried I may be doing something incorrectly, however the likely case is it doesn't support it.
Flow:
- user hits site for the first time
- user does action that triggers startTrackEvent("eventName");
- user navigates to a new page
- user does action that triggers stopTrackEvent("eventName");
-- from the appInsights readme https://github.com/microsoft/ApplicationInsights-JS/blob/master/README.md
appInsights.startTrackEvent("event");
appInsights.stopTrackEvent("event", null, {customProp1: "some value"});
ANSWER
Answered 2021-Jun-15 at 22:35Not per documentation, but via testing, can confirm that when a new page loads, appInsights will not persist start/stoptrackevent.
QUESTION
I have trouble understanding the first line of code inside this implementation of the bsearch function in C. I understand the search algorithm itself and I have played around with this function to get a good grasp of it but I still do not get what
...ANSWER
Answered 2021-Jun-15 at 21:44Within the function you need to find each element in the passed array. However the type of the array is unknown. You only know the size of each element of the array and the starting address of the array that is passed through the parameter base0. of the type const void *
..
To access an element of the array you need to use the pointer arithmetic. But the type void is incomplete type. Its size is unknown/ So you may not use the pointer of the type (const) void *` in expressions with the pointer arithmetic.
Thus this declaration
QUESTION
In C++20, we got the capability to sleep on atomic variables, waiting for their value to change.
We do so by using the std::atomic::wait
method.
Unfortunately, while wait
has been standardized, wait_for
and wait_until
are not. Meaning that we cannot sleep on an atomic variable with a timeout.
Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.
Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic
to WaitOnAddress
on Windows and it will (kinda) work with no UB, as the function gets void*
as a parameter, and it's valid to cast std::atomic
to void*
On Linux, it is unclear whether it's ok to mix std::atomic
with futex
. futex
gets either a uint32_t*
or a int32_t*
(depending which manual you read), and casting std::atomic
to u/int*
is UB. On the other hand, the manual says
The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.
Hinting that alignas(4) std::atomic
should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.
Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.
So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?
(Solutions like mixing atomics and condition variables exist, but sub-optimal)
...ANSWER
Answered 2021-Jun-15 at 20:48You shouldn't necessarily have to implement a full custom atomic
API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic
and pass it to the system.
Since std::atomic
does not offer some equivalent of native_handle
like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.
For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T
type -- at least for integral values [1]. This is an assurance that will make it possible to extract out this value.
... and casting
std::atomic
tou/int*
is UB
This isn't actually the case.
std::atomic
is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast
a T
to a value or reference of the first sub-object (e.g. the first member of the std::atomic
).
As long as we can guarantee that the std::atomic
contains only the u/int
as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

I am currently trying to build OpenPose. First, I will try to describe the environment and then the error emerging from it. Caffe, being built from source, resides in its entirety in [/Users...]/openpose/3rdparty instead of the usual location (I redact some parts of the filepaths in this post for privacy).

Answered 2021-Jun-15 at 18:43You are using cmake. The makefiles generated by cmake don't conform to "standard" makefile conventions; in particular they don't use the CXXFLAGS
variable.
When you're using cmake, you're not expected to modify the compiler options by changing the invocation of make. Instead, you're expected to modify the compiler options by either editing the CMakeLists.txt file, or else by providing an overridden value to the cmake
command line that is used to generate your makefiles.

QUESTION
I'm using PDFDownloadLink
from the react-pdf
package to generate a PDF on the fly in my application and allow the user to download a report based on data being passed to the component that generates the PDF document. However, there are more than 400 pages that need to be rendered in this PDF, and this operation blocks the main thread for a few seconds. Is there any way to make this operation asynchronous, so the rest of the application will continue to function while the PDF is being generated? Also I would like to be able to cache the results, since the data being passed to the component can come from about 8 different arrays of data, which don't change very much, so switching between these arrays I would rather not to have to render the PDF all over again if the PDF for that given array has already been generated once before... I'm guessing the blob data needs to be stored somewhere, perhaps localStorage?
ANSWER
Answered 2021-Jun-15 at 13:58I finally found the answer to this in an issue on github which addresses this exact problem:
Is your feature request related to a problem? Please describe. It is an improvement. At the moment, if you use 'PDFDownloadLink' the PDF is being generated as the component loads.
Describe the solution you'd like It is not mandatory, but having multiple heavy PDFs ready to be downloaded wouldn't be the best approach since not every user will need it.

QUESTION
I've got a requirement to be able to copy a blob from a container in 1 storage account into a container in another storage account. Previously the source container had public access set to 'Container'. I was using the connection string to connect to the account and then get a reference to the blob.
I'm using StartCopyAsync(sourceBlob). This was originally working fine when the container had public access set to container. Now it throws a StorageException of 'The specified resource does not exist'. Is this a permissions thing? I would have expected an error message to say I didn't have permissions. I can see the resource is there in the container.
Assuming it is a permissions thing, is there a way to copy a blob from a container that has public access set to 'private'? The docs suggest it can be done by 'authorised request' but what how do you do that?
Update
I've tried Gaurav Mantri's suggestion but currently getting an error of "This request is not authorized to perform this operation". Here's my code:
...ANSWER
Answered 2021-Jun-11 at 23:55It is indeed a permission issue. For copy blob operation to work, the source blob must be publicly accessible. From this link
:
When your container's ACL was public, the source blob was publicly accessible i.e. anybody could directly access the blob by its URL. However once you changed the container's ACL to private, the source blob is no longer publicly accessible.
To solve your problem, what you need to do is create a SAS URL for the source blob with at least Read
permission and use that SAS URL in your StartCopyAsync
method.
QUESTION
I read through the Bootstrap 5 docs about typography and the files _variables.scss
and _reboot.scss
. I find that there is a SASS variable $font-family-sans-serif
to set the font stack for sans serif text, but no corresponding $font-family-serif
for serif text.
FWIW: It used to be present in _variables.scss
for Bootstrap 3, but seems to missing from Bootstrap 4 as well.
Do I just declare it myself in my _variables_custom.css
or is there a canonical way to do it?
Why was it omitted from the standard Bootstrap 5 set of varaibles?
...ANSWER
Answered 2021-Jun-15 at 09:29Bootstrap (in its SCSS source format) is a framework - a stating point if you will - so it's expected that you add your own variables & elements and/or modify the existing ones. There is no $font-family-serif
because its just not required for that core code.
As to how to customise - start with https://getbootstrap.com/docs/5.0/customize/sass
Why was it omitted? - Refactoring. Removing "dead code" (obsolete variables, parameters, fields, methods and/or class') is a very common "code cleaning" practice. A serif font is just not used, so it got deleted. (Not even in BS3 was it "used". It was declared, but not referenced in anything except the customizer.)
But that's the beauty of frameworks - you can just add/delete/change it yourself. :)
