QUESTION
I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.
Let's say I have these instructions:
...ANSWER
Answered 2021-Jun-15 at 16:34It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.
QUESTION
I am developing an automated document preparation process within our Office365 environment (Word Template, SharePoint etc.) and are using Power Apps and Power Automate to prepare and send the document for authenticated signatures via Docusign. I do not want to use the 'out of the box' Docusign Power Automate connectors as I am need to invoke some of the more advanced Docusign capabilities within my Power Apps solution.
I have successfully developed my own Custom Connectors in Power Apps and Power Automate using the REST API capabilities with Docusign and successfully accomplished Oauth2 user authentication and been able to create envelopes and send documents for signature to a single recipient.
My problem is that I am wanting to send a document to multiple recipients using the V2.1 document REST API standards however, it seems I am bumping into an issue with the custom connector in Power Apps/Power Automate.
To ensure I had a correctly constructed JSON list, I used the built in Docusign API development environment sending the document to multiple recipients along with a document anchortag. It functioned correctly and resulted in the following JSON code:
...ANSWER
Answered 2021-Apr-12 at 17:20Ok, so after crafting the question and issue above, it got me thinking about maybe importing JSON payload directly into the test page (using RAW Body display) and then tested the connector. I was surprised that the JSON code ran with MULTIPLE recipients yet, when I selected back from RAW Body mode), the test page only showed one recipient. This is very misleading.
I then thought that perhaps the connector was configured correctly and it was just a limitation in the connector test process.
I went back to Power Automate and used the multi recipient connector in my flow and was surprised to see that I now had the ability to add multiple recipients and each recipient could be set up with multiple anchor tags.
In summary, the custom connector test is a basic test environment. Going forward, I would use my full JSON payload in the RAW Body view and test it that way. Also, you need to configure the JSON payload to show multiple components to enable Power Automate to configure the use of the connector with these multiple elements.
I think this issue is worth doing a video tutorial on as I am sure many other people will bump into the same issue.
QUESTION
Preface - please, before marking as duplicate, I realize this general question has been asked and answered many times. I'm posing a very specific use case, which couldn't reasonably be conveyed in the question title, and looking for an answer specific to this case. With all due respect, please don't bother with speculative answers. I've speculated plenty, I'm looking for a definitive answer backed by specific knowledge or documentation of the PostgreSQL query planner.
Given this table and this query,

Answered 2021-Mar-27 at 15:49I think the comments so far have summed it up, thanks.
This is just a result of having no data, so no statistics, and probably is just an arbitrary choice.
I'll update and maybe change the title accordingly once I've verified with data.

What would be the best way to achieve this in Laravel? I'm mentioning Laravel specifically because I'm still rather new to Laravel. I'm trying to implement it therein, and I'm sure there's an aspect of Laravel that I'm not familiar with yet that will solve this elegantly.

QUESTION
I would like to enforce a filesystem check on my bitbake
'd image. If I understand correctly I need to add fsck=force
and fsck.repair=yes
to /proc/cmdline
. Is this approach correct? What is the right way to do modify /proc/cmdline
?
EDIT: I ran oe-pkgdata-util find-path /proc/cmdline
which exited with ERROR: Unable to find any package producing path /proc/cmdline
. Thus, I speculate it is generated during kernel compilation. Is that correct?
ANSWER
Answered 2021-Jan-19 at 10:02;tldr add your stuff to bootargs
variable in U-Boot
First of all, yes, your approach is correct - you need to pass two arguments fsck=force
and fsck.repair=yes
as boot arguments to your kernel while booting. But you are looking in the wrong direction. All this stuff is about booting and Linux kernel, not actually about Yocto or bitbake.
There are several ways to pass boot arguments to kernel, like
- hardcode into kernel code (brute-force option, you'll have to dig sources:) )
- use
CONFIG_CMDLINE
kernel config (docs say bootloader args would be appended to it) - pass arguments via bootloader (the most flexible and usable way)
- pass arguments by
.dtb
-file (Device Tree Binary file, more of this here) - invent something else, as Linux kernel is a DIY swiss-army-knife
Using CONFIG_CMDLINE
is easy - just append your to this variable like
QUESTION
I'm trying to create a browser extension popup (in JS) that creates a number of buttons with links that open up different webpages. The function takes a number of parameters, the main one being b_link which is an array of URL's to the website. For some reason, only the last URL in array is applied to all of the buttons that are created.
I'm not entirely sure what the problem is, I could speculate but I don't think that would be productive. One thing I did notice and had to compensate for was using b_link
in the lambda function. Just using b_link[i]
, the lambda function only saw undefined so no webpage opened, but using var tmpLink = b_link[i];
at least gets the link into the function and allows a webpage to open.
How should I make these buttons so that they all have their own links, rather than only the last one in the array?
The function in question:
...ANSWER
Answered 2021-Jan-11 at 19:19I found a way to do this via creating an a
element, setting href via a.href = tmpLink
and appending the button to the a
element as a child. The final function is:

...ANSWER
Answered 2020-Nov-22 at 16:40All elements of my problem result from:
- bug in gnuplot 5.4.0
- make invokes /bin/sh (linux bash) instead of the windows shell.
I submitted a bug report on gnuplot 5.4.0 in cygwin distribution to the gnuplot development group (https://sourceforge.net/p/gnuplot/bugs/2368/). The developer says it will be fixed in 5.4.1.
The bug results from deprecated $0, $1, $2 etc symbols being erroneously enabled and assigned to gnuplot (5.4.0) to command line arguments.
The bugged Gnuplot 5.4.0 is “gnuplot-base.exe” and the “obsolete” gnuplot 5.2.8 appears in the cygwin distribution as “gnuplot.exe”.
I observe command “gnuplot”:
- from a windows cmd shell runs “gnuplot.exe” (5.2.8).
- whereas from /bin/sh links to gnuplot point to “gnuplot-base.exe”(5.4.0).
The “make” utility submits rules through /bin/sh explaining why gnuplot fails in “make” but not from the command shell.
I’m working around by calling “gnuplot.exe” instead of “gnuplot” in "make" rules. “gnuplot.exe is the obsolete version 5.2.8.
Thank you. I love you all.
