No plank configuration file

I want to manually customize my plank dock, but when I go to the plank directory looking for the settings file, I find only only the launchers directory, and not what I’m looking for. I already searched on some forums, but everybody recommend to use docky or others dock, which are not available for ubuntu 19.04, the version I’m actually using. Does somebody knows how to solve this?

P.S. sorry for the english

Customization mistakes and changing the layout type of a core page configuration xml

In the official M2 docs we have this quote

Changing handle inheritance. For example, you should not change the page type parent handle.

Pulled from here M2 Frontend Dev Docs

By this I understand you should not make changes like 1column -> 3columns. If this means something else please correct me. If I’m right, what are the reasons for which this is bad practice?

What is the recommended way to change the layout of a page? If this is considered a bad practice?

Telling Probability of Point Configurations being in Convex Configuration from Vertex Degree in Planar Euclidean MSTs


Question:

what is the probability that four distinct points in general position in the Euclidean plane are in convex configuration, depending on the number of leaf nodes in their MST?

I assume that a quadruplet of points has a higher probability of being in convex configuration if its MST has two leaf nodes than if it has three, but that that probability is less than 1.

OpenRCT2 cmake configuration failed on Debian Stretch: cmake isn’t desired version

I was trying to build OpenRCT2 on Debian Stretch (9.9.0 amd64) with cmake, following the guide on https://github.com/OpenRCT2/OpenRCT2/wiki/Building-OpenRCT2-on-Linux, but unfortunately I have an invalid cmake version. After running the command sudo cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo, the terminal spits out:

  CMake 3.9 or higher is required.  You are running version 3.7.2   -- Configuring incomplete, errors occurred! 

I have tried to reinstall cmake, but I still have ver. 3.7.2. How do I update cmake’s version in Stretch?

MySQL 8 installation fail – dpkg: dependency problems prevent configuration of mysql-server:

I wasn’t able yet to install MySQL 8 in Ubuntu.

Linux : Ubuntu 18.04.2 LTS (running on windows using WSL) Kernel : 4.4.0-17134-Microsoft Mysql-server : 8.0.16-2ubuntu18.04 amd64

I am following those instructions – Steps for a fresh installation of MySQL : https://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/#apt-repo-fresh-install

Deb Package downloaded : (mysql-apt-config_0.8.13-1_all.deb)

I have tried some suggestions that I found at the internet, based on similar cases, but none of them worked. Example : sudo apt -f install -> In order to fix the dependency problem.

After the installation, I run the command to start the mysql server, but the service isn’t recognized, so the installation fail.

Based on my experience, it’s very hard to evaluate exactly the root cause of the problem, any suggestion recommendation and suggestion would be really appreciated.

I am planning to follow this installation process My SQL Community Server, https://dev.mysql.com/downloads/mysql/, where I can select the packages to be installed.

Preconditions (*)

  1. Magento 2.3.1

Working in dev environment and and enabled few optimization parameters which made admin panel inaccessible and buttons were don’t appear correct with proper text , appears shrinked. Admin panels don’t draw out even if does then none of the buttons registers a click and hence I’m not able to change the configurations back. Steps to reproduce (*)

but no avail.

Is it practical to have several subnets under a ethernet port for a dhcp configuration?

Does it make any sense to set several subnets on a ethernet port of DHCP server. The configuration on dhcpd.conf is listed below and the server has no complain, but it is doubtful:

subnet 192.168.10.0 netmask 255.255.255.0 { #ethernet port enp5s0; range 192.168.10.100 192.168.10.120; range 192.168.10.200 192.168.10.220; option domain-name-servers 1.1.1.1, 2.2.2.2; option routers 192.168.10.1; default-lease-time 86400; max-lease-time 259200; } subnet 192.168.30.0 netmask 255.255.255.0 { #ethernet port enp5s0; range 192.168.30.100 192.168.30.120; range 192.168.30.200 192.168.30.220; option domain-name-servers 1.1.1.1, 2.2.2.2; option routers 192.168.30.1; default-lease-time 86400; max-lease-time 259200; } subnet 192.168.40.0 netmask 255.255.255.0 { #ethernet port enp7s0; range 192.168.40.100 192.168.40.120; range 192.168.40.200 192.168.40.220; option domain-name-servers 1.1.1.1, 2.2.2.2; option routers 192.168.40.1; default-lease-time 86400; max-lease-time 259200; }

How do you fix an Apple Hardware Test (AHT) configuration?

I have two MacBookPros on which I run 10.6.8. One has a Core i5 (MacBookPro6,1), the other a Core i7 (MacBookPro8,3). I move the SSD from one to other as occasion or whim demands. On the Core i5, AHT runs successfully. On the Core i7, AHT fails to launch. Before the machine shuts down, it briefly displays a window with the error: “Apple Hardware Test had trouble reading env file Configs\AHT_default.env”.

Where is this file located? (note the “\” in the file name). How do I repair it?
