Cumulus | ☁️ A SoundCloud player that lives in your menubar | Menu library

So I was working on a hackerrank easy problem. It was actually pretty easy but I'm caught on something that I'm sure is very small but I can't find it and I was hoping you guys could help pinpoint the problem.

The name of the problem is "Jumping on The Clouds" and a paraphrased summary is this:

"The player can jump on any cumulus cloud having a number that is equal to the number of the current cloud plus 1 or 2

. The player must avoid the thunderheads. Determine the minimum number of jumps it will take to jump from the starting postion to the last cloud. It is always possible to win the game.

For each game, you will get an array of clouds numbered 0 if they are safe or 1 if they must be avoided. "

To simplify, you get an array of 0's and 1's and you must find the minimum amount of jumps it takes to get to the end of the array. You can only jump 1 or 2 spots at a time and you are guaranteed that the last cloud is "safe".

I immediately saw that this could be solved two ways, 1. as a graph theory problem, 2. as a tree implementation.

I chose to use the tree implementation.

Here is my code:

I am using ubuntu 18.04 with virtual machine for running my program in remote GPU server. I ran my program in docker and I want to transfer plot files in docker container to local file directory in my virtual machine. I used scp to transfer local files from virtual machine to docker container, but now I want to transfer result of my program, plot file back to local file directory in my virtual machine. How can I do this in ubuntu? any idea?

here is what I did previously:

I am trying OSPF Unnumberd and i have a VM (CentOs) and a Switch (Cumulus-Vx). When i try to ping from the Switch interface 1 to the Vm the Vm-Interface recieves the ICMP echo request but doesnt answer. When i look into the forward routing table i dont see the other router but with vtysh i see it. THe Target Router is the 10.1.0.1

So im solving a hackerrank challenge called "Jumping on the clouds" and it involves taking the least amount of steps to get to the end. Ill summarize the problem:

Emma is playing a new mobile game that starts with consecutively numbered clouds. Some of the clouds are thunderheads and others are cumulus. She can jump on any cumulus cloud having a number that is equal to the number of the current cloud plus 1 or 2 . She must avoid the thunderheads. Determine the minimum number of jumps it will take Emma to jump from her starting postion to the last cloud. It is always possible to win the game.

The "list" of clouds is given in a vector of 0's and 1's. 0's are "safe" 1's Emma can not jump to.

The function we receive is a vector of 0's and 1's like so:

I am trying to make sure javascript displays the image title for every image on the screen. I seem to have found out how to convert the title as text node but I have no idea how to make sure the text only shows when the image is on-screen and goes away when the image goes off-screen.

Plain javascript only please. Thank you.

I have a angularJS list that I would like to implement several filters, one will be a custom filter.

Based on Dynamic orderBy in AngularJS I try to implement a dynamic sort function with parameters. It's not working properly because the default sort is being called. How can I make it not calling the default sort by name?

I have 2 buttons to call the function and send the parameter.

When I insert a date from a file that has it formatted "dd/mm/yy" into my database table with the date formatted "yy/mm/dd" the date is wrong:

Instead of getting 2019:04:11 I get 2011:04:19.

I want to keep the database format ("yy/mm/dd")

I have tried:

actualdate = DATE_FORMAT(j[0], '%y-%m-%d')

cursor.execute(actualdate)

but it tells me error: name 'DATE_FORMAT' is not defined

I don't know how to insert a list of info into a mysql database.

I'm trying to insert rows data into a database but it is simply inserting the last row three times. The list is named "t" and it is a tuple .

Data:

11/04/19,17:33,33.4,55

11/04/19,17:34,22.9,57

11/04/19,17:35,11.9,81
