QUESTION
and I appreciate in advance for your help on this. I have a VPS with the following specs:
OS: Centos 7.x CPU Model: Common KVM processor CPU Details: 6 Core(2200 MHz) Distro Name: CentOS Linux release 7.9.2009 (Core) Kernel Version: 3.10.0-1160.25.1.el7.x86_64 Database: Server type: MariaDB Server version: 10.2.38-MariaDB - MariaDB Server
And here is mu sqltuner output from letting it run after 48 hours and uptime.
...ANSWER
Answered 2021-May-24 at 18:37Rules for memory allocation.
- Do not allocate so much RAM that swapping will occur. Swapping is terrible for MySQL/MariaDB performance.
- Do adjust
innodb_buffer_pool_sizesuch that most of RAM is in use during normal time and even for spikes in activity. (I often say "set it to 70% of available RAM", but you are asking for more details.) - Do not bother changing other settings; they add to the complexity of "getting it right".
There are 3 situations (based on innodb_buffer_pool_size and dataset size):
- Tiny dataset -- buffer_pool is bigger than necessary --> wasting some of RAM, but so what; it is not useful for anything else. And it give you some room for growth.
- Medium-sized dataset -- Most activity is done in RAM; the system will run nicely.
- Big dataset -- The system may be I/O-bound. Adding RAM is a costly and brute force solution. However, some software techniques (eg, better indexes) may help, such as this for WordPress and WooCommerce.
QUESTION
The time.sleep is at the end but somehow it the code starts with time.sleep first. I want it to pick a random name then wait for 30 seconds. After 30 secounds i want it to pick a random number from 0 to 100. This is for two players. I want it too display the 2 names first then wait for 30 secs then show 2 random numbers bellow the player 1 and player 2 text
...ANSWER
Answered 2021-May-10 at 00:51You have the program sleeping before the call to display.update. Things are only displayed when this is called, so it waits 20 seconds. Move display.update above the sleep call.

following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.
You can use the trim function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I am working on assigning random priorities (i.e. high, medium, low) to a list for a ServiceDesk assignment.
Before that, I was wondering how to go about storing (and printing) an array in said priority queue. This is currently what I have.
*UPDATED CODE
...ANSWER
Answered 2021-Apr-18 at 02:33Sounds like you are asking for help on how to get started. You are asking for help on learning to learn. Here is how I would approach your problem:
Apparently you are supposed to use a priority queue.
- Write a tiny program that makes a priority queue and stores strings into it, then prints them out.
- Define a class and store instances of that class into the priority queue instead of strings.
- Modify the sort criteria on the priority queue and notice that the printed sequence changes according to the sort criteria.
- Write a function that creates one class instance with random values.
- Write a function that creates all 100 class instances.
- Declare victory.

My problem is that I have a header that is supposed to take up the whole top of the page but for some reason, there is a margin on both sides.I tried * margin :0 padding :0 but doesn't work.

QUESTION
In my django template I want to access the bio prop of an instance of my Creator class. This bio is set up as a QuillField in the Creator model class. When I try to access creator.bio, all that renders to the page is the following:
What I want is the actual paragraph of formatted text (ie. the bio) that I typed into the form and saved. As of now, the QuillField is only accessible through the form in the Django admin page. The problem has nothing to do with the Quill UI, but rather being able to access the text I wrote into that form field and render it to the page in a readable format.

QUESTION
We recently upgraded from mysql 5.6 to mysql 8.0 on a few servers, one of the servers was fine, and has had no problems, but it has significantly less load than one of our other servers which has been running out of memory.
Our server launches, then grabs 300 connections, and keeps them open with a C3P0 pool to the mysql server.
We were running these servers on AWS on MySQL 5.6 with the same overridden parameters on 8GB of RAM, when we upgraded to MySQL 8.0.21 we started running out of RAM in about 1 day. We grew the server to 32Gb but didn't change the parameters. It's gone over 15 GB used and still going up.
We're pretty sure it's related to the per connection thread memory, but not sure why. From looking at MySQL tuner it looks like the variables that control per thread memory are:
...ANSWER
Answered 2021-Jan-18 at 19:41You're calculating the per-thread memory usage wrong. Those variables (and tmp_table_size which you didn't include) are not all used at the same time. Don't add them up. And even if you were to add them up, at least two might be allocated multiple times for a single query, so you can't just sum them anyway.
Basically, the memory usage calculated by MySQLTuner is totally misleading, and you shouldn't believe it. I have written about this before: What does "MySQL's maximum memory usage is dangerously high" mean by mysqltuner?
If you want to understand actual memory usage, use the PERFORMANCE_SCHEMA, or the slightly easier to read views on it, in the SYS schema.
The documentation for PS or SYS is pretty dense, so instead I'd look for better examples in blogs like this one:

QUESTION
I’m using a-frame and trying to accomplish this task - force the canvas to be rendered as “landscape” when a mobile device is in portrait orientation (ie. device-width = 414px and device-height = 736px).
I have successfully accomplished this with the following steps
...ANSWER
Answered 2021-Jan-15 at 02:33A-Frame uses a Raycaster internally to determine if the spot you clicked has hit an object. You can see in the Three.js documentation the raycaster needs the mouse x&y coordinates to determine where you clicked. Here's a working demo of that concept. However with your setup, x, y turns into -y, x.
I think you'll have to write your own Raycaster function to trigger on the click event instead of relying on the built-in AFrame functionality, and then swap the x&y values:
