| Is it possible to limit the amount of variations a user can do with woocommerce Posted: 30 Oct 2021 07:07 AM PDT A lot of the Q&A I'm finding online is about increasing the amount of variations you can make on a woocommerce variable product but I'm trying to limit the amount to 30. The reason being on some client sites I have done, they have like over 1000 variations which makes the product take an age to load. I'm creating a multivendor site so I'm trying to prevent problematic products from the get go. Some of the functions I have tried are: add_filter( 'woocommerce_ajax_variation_threshold', 'ww_ajax_variation_threshold', 10, 2 ); function ww_ajax_variation_threshold( $default, $product ) { return 30; }
and also function wpse_rest_batch_items_limit( $limit ) { $limit = 30; return $limit; } add_filter( 'woocommerce_rest_batch_items_limit', 'wpse_rest_batch_items_limit' );
These don't seem to work for me unfortunately. I also want to try and replicate this in the variation popup message. (see below) 
Does anyone know if something like this is possible?  |

| I would like to divide it into command, key, and value through input split and enter it in the dictionary Posted: 30 Oct 2021 07:07 AM PDT database = {} while True: print("Pleas type like Command,textA,textB") Command, textA, textB = input().split(',') if Command == 'PUT': // ex: PUT,a,c PUT is command to a is key, c is value database[textA] = textB print("Success!") elif Command == 'GET': // ex: GET,a GET is command to get a's value if "textA" in database: print(database.get('textA')) else: print("Not exist!") elif Command == 'DELETE': // ex: DELETE,a DELETE is command to delete a's key&value if "textA" in database: del database['textA'] print("Success!") else: print("Not exist!") elif Command == 'LIST': if "textA" in database: for KEY, VALUE in database.items(): print(KEY, VALUE) else: print("Not exist!")
I would like to receive a command and key value in the dictionary and operate the if statement according to each command. However, if statement works only when three values are received unconditionally, so GET, DELETE, and LIST cannot be used. I'm trying to use TRY and EXCEPT, but I don't understand well. Also, if you enter textA and textB exactly like that, I wonder if Key and Value will continue to be stored in the Dictionary Database. There are many restrictions because the input format is Command, textA, and textB unconditionally. I think I have to organize it with a repeat sentence, but I wonder if there is another way.  |

the basic way it works is that it gets each pixel color data of an image and prepares a correct ANSI code for the color; ESC[38;2;{R};{G};{B}m
then in a later stage printing it i have been looking into a way to speed up the printing process IE, using stdout, using a separate loop to generate the data and to print it, i even tried to use multiple threads (i know how stupid that sounds...), using alternative buffer, but in the end i got mostly fractions of a speed increase. is there any way, even a crazy one, that would significantly speed up this process?  |
| What is the real-time memory performance of modern server CPU's? Posted: 30 Oct 2021 07:08 AM PDT At time of writing, high-end CPUs support 8-channel DDR4 at 3200 speed. This gives a theoretical memory bandwidth of 204 GByte/s. With "real-time memory performance" I mean that a device reads / writes a certain amount of data over PCIe and the requests are serviced in the microsecond range or better. The transfer should be able to run for minutes, without experiencing larger delays even once. This is the background of my question: My device writes about 12 GByte/sec over PCIe 3.0 x16. At the same time, the data is stored on a NVME drive array over PCIe 4.0 x16. My current CPU is marketed to support 204 GB/s memory bandwidth. According to my (naive?) calculation, this bandwidth is used to (12+12)/204= 12 %. Therefore I expected it to run smoothly. In reality, the DMA is sometimes delayed for up to 100 us. Not very often, but it happens several times a second. The CPU cores aren't doing much, by the way. And I know for sure that the delay is not caused by interrupts and such. (My DMA engine runs without any software intervention.) Prioritizing this PCIe connection in BIOS didn't help. Am I asking too much? Are these chips just not built for real-time performance? Does DDR4 need some kind of periodic recalibration / housekeeping? Are there CPUs available that can handle this traffic? [Edit] The write DMA itself is working fine, for several minutes. But as soon as I start accessing the disk at the same time (e.g. CrystalDiskMark) the write DMA starts to stutter.  |

| How to make sure the email is logged in only once? Posted: 30 Oct 2021 07:07 AM PDT I created a small chrome extension for a specific scope of users. How can I make sure that a user is logged in only on one machine to avoid sharing the Extension without users paying for it? Is there any way to do so? With other apps I check the UUID and compare it against my list of users. I struggle to understand the identify API tbh. This is my way currently but it only tracks if the user is in my list. It is inside my popup.JS file so it gets triggered when the users click on the extension icon.

| Slow rollup.js bundling after copying in a 3rd-party library Posted: 30 Oct 2021 07:07 AM PDT I'm using https://shoelace.style (in my Svelte project), and following the example config in shoelace docs, I added a copy() plugin to my rollup.config.js, copying it to public/vendor/shoelace: export default { // SNIP plugins: [ // SNIP copy({ targets: [ { src: path.resolve( __dirname, "node_modules/@shoelace-style/shoelace/dist/assets" ), dest: path.resolve(__dirname, "public/vendor/shoelace"), }, ], }), // SNIP ], };
It works, but now the build takes really really long - upwards of 40s, including incremental rebuilds on file change. I am fairly sure the time loss isn't because it's accidentally copied every time, as the asset folder is just 6M. So, I suppose there's some tree-shaking and/or optimizations going on? Is there way to exclude the folder from rollup processing - or to troubleshoot/profile the bundling process anyhow? (If necessary, I can also post the rest of the config; but it's otherwise standard new app template obtained by npx degit sveltejs/template and adding/removing the copy plugin made all the difference.)  |

I also notice that 3 files are created in the software directory: Snap*****.trc, javacore*****.txt, and core*****.dmp In the text file, I have the following: NULL ------------------------------------------------------------------------ 0SECTION TITLE subcomponent dump routine NULL =============================== 1TISIGINFO Dump Event "gpf" (00002000) received 1TIDATETIME Date: 2014/12/10 at 18:17:57 1TIFILENAME Javacore filename: C:\IBM\InformationServer\Clients\Classic\javacore.20141210.181756.4956.0002.txt 1TIREQFLAGS Request Flags: 0x81 (exclusive+preempt) 1TIPREPSTATE Prep State: 0x100 () 1TIPREPINFO Exclusive VM access not taken: data may not be consistent across javacore sections NULL ------------------------------------------------------------------------ 0SECTION GPINFO subcomponent dump routine NULL ================================ 2XHOSLEVEL OS Level : Windows XP 5.1 build 2600 Service Pack 2 2XHCPUS Processors - 3XHCPUARCH Architecture : x86 3XHNUMCPUS How Many : 4 3XHNUMASUP NUMA is either not supported or has been disabled by user NULL 1XHEXCPCODE J9Generic_Signal_Number: 00000004 1XHEXCPCODE ExceptionCode: C0000005 1XHEXCPCODE ExceptionAddress: 09C40340 1XHEXCPCODE ContextFlags: 0001007F 1XHEXCPCODE Handler1: 0846A120 1XHEXCPCODE Handler2: 084CC0E0 1XHEXCPCODE InaccessibleAddress: DD55B4BF NULL 1XHEXCPMODULE Module: C:\IBM\InformationServer\ASBNode\apps\jre\bin\j9ute24.dll 1XHEXCPMODULE Module_base_address: 09C30000 1XHEXCPMODULE Offset_in_DLL: 00010340 NULL 1XHREGISTERS Registers: 2XHREGISTER EDI: DD55B4BF 2XHREGISTER ESI: 0853F2E0 2XHREGISTER EAX: DD55B4BF 2XHREGISTER EBX: 08FD96F0 2XHREGISTER ECX: 08FDAB28 2XHREGISTER EDX: DD55B4C0 2XHREGISTER EIP: 09C40340 2XHREGISTER ESP: 0028CA9C 2XHREGISTER EBP: 08EA5D00 2XHREGISTER EFLAGS: 00010216 2XHREGISTER GS: 002B 2XHREGISTER FS: 0053 2XHREGISTER ES: 002B 2XHREGISTER DS: 002B NULL 1XHFLAGS VM flags:00000000 NULL NULL ------------------------------------------------------------------------ 0SECTION ENVINFO subcomponent dump routine NULL ================================= 1CIJAVAVERSION 1INTERNAL An exception occurred attempting to access in-flight data.

| AngularJS: Using css media query for screen resize Posted: 30 Oct 2021 07:07 AM PDT I have an existing CSS, it does media query and displays a message box when the screen is resize to a certain size. I want the message box to disappear after 5 seconds. Any idea how to do it in AngluarJs? CSS: @media all and (max-width: 1024px), all and (max-height: 760px) { div#bestview { display: block; position:fixed; z-index: 9999; /* above everything else */ top:0; left:0; bottom:0; right:0; background-image: url(../img/transpBlack75.png); } }

| Is it a bad practice to use a ThreadLocal Object for storing web request metadata? Posted: 30 Oct 2021 07:07 AM PDT I am working on a j2ee webapp divided in several modules. I have some metadata such as user name and preferences that I would like to access from everywhere in the app, and maybe also gather data similar to logging information but specific to a request and store it in those metadata so that I could optionally send it back as debug information to the user. Aside from passing a generic context object throughout every method from the upper presentation classes to the downer daos or using AOP, the only solution that came in mind was using a threadlocal "Context" object very similar to a session BTW, and add a filter for binding it on ongoing request and unbinding it on response. But such thing feels a little hacky since this breaks several patterns and could possibly make things complicated when it comes to testing and debugging so I wanted to ask if from your experience it is ok to proceed like this?  |
| Floats, Decimals, or Integers Posted: 30 Oct 2021 07:08 AM PDT I have a rails app that process some data, and some of these data include numbers with decimals such as 1.9943, and division between these numbers and other integers. I wanted to know what the best way to store this was. I thought of storing the numbers that would retain integers as integers and numbers that could become decimals as decimals. Although it was in a weird format like #<BigDecimal:7fda470aa9f0,'0.197757E1',18(18)>
it seems to perform the correct arithmetic when I divide two decimal numbers or a decimal with an integer. When I try to divide integers with integers, it doesn't work correctly. I thought rails would automatically convert the result into a proper decimal, but it seems to keep it as integer and strip the remainders. Is there anything I can do about this? And what would be the best way to store this type of information? Should I store it all as decimals, or maybe floats?  |
