how can i rank my keyword on Amazon Search engine
I’ve a Debian GNU/Linux 9 (4GB, 2 CPUs) on Digitalocean. Tonight (I’ve done nothing) my DB (mariaDB) crashed with this errors. I ran a wordpress with InnoDB and myISAM tables:

Here my first page of htop
Could not export/copy htop result.
I would be happy if you could help me out!!
Thanks a lot
So,i’m having a bit of an issue with instantiating my gameobjects into to universe(My Scene object).
I can create an empty object from scratch and populate it from there with ease,my problem starts when i try to clone the gameobject which i just created.
My steps are
It seems when i try to clone components,it returns only the base class pointer.There i try to recreate the derived class and add it to new gameobject’s component list but obviously i fail.
This is my GameObject AKA RGameElement
This is my Component AKA RElementComponent
and this my Instantiate via gameobject ref function
I want to decentralize my databases and upload it to Sia Skynet to give the users the ability to search on front-end. It is important to be able to deal with large amounts of data, but the RAM-based in-browser SQL engines (MiniSearch, AlaSQL, etc) are limited.
Yeaterday I made a demo: I sorted and partitioned my key-value database into 1000 line files and I made an index for the files also. You can try out my demo here, or check it out on GitHub
So my question is that are there any better solutions for large-in-browser databases? (I don’t really want to reinvent the wheel 😆)
I’m trying to get the physics of a retractable object in unity,
So I will be able to “launch” an elastic cable (similar to rope physics) out of an object (e.g. A gun),
And the cable will gradually/exponentially “roll back” into the object.
A good reference would be Batman’s grapple gun.
I thought of utilizing it using a spring joint, but I can’t really get the exact mechanics I’m trying to achieve.
Thank you in advance.
I am trying to find a really good animation tutorial for Unreal Engine 4 that covers how to do things like have the character react to where objects are and what is happening like when falling, picking items up, uneven ground, and other more complicated aspects to animations in games. I mostly make shooters and have I think a good grasp of animation blueprints. I’ve looked all over for tutorials on YouTube and Udemy but all of them simply cover blend spaces, anim offsets, and the event graph and animation blueprint. I have all of this down and have created a fully fledged blueprint that works for a third person shooter, it looks decent but looks really basic and not dynamic. Here’s an example of what I want to learn to do: Example. It looks dynamic with things like the body bending as he runs, grabbing ledges, vaulting, and ragdoll physics when he fell into a truck. It all looks fluid and not like a bunch of free looping animations from the marketplace which is what my game looks like. The feel of a game I’m going for is something like Squad incase that helps with any answers but I mostly just want to learn more about animation in UE4 so if you could recommend a tutorial to help with this that would be awesome, thanks!
I am trying to use the Minimum Translation Vector (MTV) returned from the SAT algorithm for simple collision response. Please see the example below.
By separating the colliding boxes by moving the black box along the MTV, the box is now colliding with the other green box below. Moving the black box along the MTV for the collision with this new box then brings the box back to colliding with the first box, and an infinite cycle of trying to separate the boxes begins.
Am I missing something, or is collision response not possible using the MTV?
The compute instances I’m running is a Debian Buster. Normally there’s exists a
/etc/bash_completion file. However for GCE, it’s missing. There’s even a section they’ve added in the default
~/.bashrc to refer to the bash completion files which none of them exists.
if ! shopt -oq posix; then if [ -f /usr/share/bash-completion/bash_completion ]; then . /usr/share/bash-completion/bash_completion elif [ -f /etc/bash_completion ]; then . /etc/bash_completion fi fi
I have a domain, andrasnovoszath.com which previously I redirected to another one bcdataanalytics.com. About a month ago I stopped the redirect and started to write posts on it as on a separate site.
Google does not index the pages, save a few early ones, and only one later one. Even more, in the search results, it shows a page from bcdataanalytics.com, that is, from the page to where I redirected this page previously.
I checked and the google search console seems to believe that the canonical page is the one I was redirecting to (even though there is no overlapping content at all):
User-declared canonical: https://andrasnovoszath.com/andrasnovoszath.com/
Google-selected canonical: https://www.bcdataanalytics.com/
I requested reindex multiple times but that did not help.
I reviewed this StackExchange for similar issues but most of the canonical problems were about actual duplicate content or slight variations of the same URL (e.g. translations). The closest thing I found was this but there is no solution.
I would appreciate any tips, ideas on how to approach the problem. Thanks!
The sites who moved up in the rankings may have gotten quality links that boosted their relevancy (as opposed to you losing relevancy).
You may have lost quality links
The sites that leaped ahead of you made big improvements in their SEO and now are reaping the rewards
There was a small algorithm change that played to the other sites’ strengths
There was a small algorithm change that played against your weaknesses
Also keep in mind that rankings naturally fluctuate. It’s very possible you will return to your previous rankings soon without having to change anything on your site.
One thing you should do is check to see if any of the sites that moved ahead of you are new or if they made any changes (if you don’t check out the competition regularly you may not be able to do this). If so, you may want to make similar changes and see if it helps you. Be prepared to roll the changes back if they do not help or hurt your rankings.
My advice whenever someone has this occur is always don’t panic and don’t change anything. This is a perfect opportunity for you to make changes that you really don’t need to make and they end up hurting you in the end.
If your content is still strong then wait it out. Keep getting links to your pages. Don’t panic. Be patient.
To diagnose a drop you need to:
Undo any recent changes and wait to see if your rankings revert back.
Make sure you are up to date on Google’s latest changes to their algorithm and see if any of them apply to you. If so, make changes that should affect that algorithm change and wait to see what happens. If nothing changes then rollback your content as that was the last known well-ranking format for your content.
That’s about it. If you didn’t change anything and Google hasn’t made any announced changes then you have to assume your competitors got better either through better content/SEO or minor tweaks at Google that were unannounced and difficult to test for. In this case just keep plugging away. If your content is strong, you will regain your old positioning at some point.
