canonical-kubernetes disappeared?

I’m following the instructions at The charmed distribution of kubernetes

But seems that the kubernetes spell doesn’t exist

sysop@kvmnode1:~$   sudo snap install conjure-up --classic [sudo] password di sysop:  conjure-up 2.6.7-20190521.1305 from Canonical✓ installed sysop@kvmnode1:~$   conjure-up canonical-kubernetes [error] Can't find a spell matching 'canonical-kubernetes' 

How can I install kubernetes using conjure-up?

Find All Numbers Disappeared in an Array

The task is taken from leetcode

Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once.

Find all the elements of [1, n] inclusive that do not appear in this array.

Could you do it without extra space and in O(n) runtime? You may assume the returned list does not count as extra space.






My solution

/**  * @param {number[]} nums  * @return {number[]}  */ var findDisappearedNumbers = function(nums) {   return nums     .reduce((arr, x) => {       arr[x - 1] = null;       return arr;     }, Array.from({length: nums.length}, (v, k) => k+1))     .filter(Boolean); }; 

There has to be a more elegant solution to that.

Frequent contacts disappeared

I have a Moto G5 with Android 7.0 and Phone 3.00.00.

It used to be the case that when I called one of my contacts, they would appear in the “Speed dial” tab of the phone app, just after my favorite contacts. For some reason, my phone app’s speed dial tab doesn’t show any frequent contacts any more. Only favorite contacts appear. The call history tab still shows these calls, so I am using that for now.

Do NOT ask me to look for a “Show frequently contacted” setting. I have checked both the phone app’s settings and the contact app’s settings and I don’t see a setting for “Show frequently contacted” which seems to be a Samsung setting.

Desktop Icons disappeared

I have already searched among many posts but I have not been able to solve, my problem is that since I updated to 18.04 I no longer see the icons on the desktop.

Through Gnome Tweaks if I try to enable the “Show icons” option a strange thing happens: the icons do not appear, but instead the Home folder opens By the way, the Home folder opens automatically whenever I start the PC, I think there could be a correlation but I don’t know how.

Following another thread I downloaded the “Desktop icons” extension (that was missing) and with that I can finally see the icons, I can open the files but I can’t move them or delete them, so I guess it’s not the correct solution. In addition, even with Desktop icons, the Desktop settings in Tweak Tools have no effect.

Can anyone help me?

Settings app disappeared

I’ve had this happen before and I did a refresh installation to fix it the first time but I don’t want to go through that again if I don’t have to. I have no settings app (pop_OS 19). I used to get to it by hitting super then typing settings. It no longer shows up. I also cannot find it if I click “All Applications”. Is there a way to get it back without reinstalling?

SharePoint 2010 Search crawl gatherer’s temp folder got disappeared

I have 1 application server with SharePoint 2010 SP1 installed and another for Database SQL server 2008 R2. Suddenly the Temp folder for search crawl got disappeared and due to this search crawling got failed. It was fixed by manually creating those temp folders.

But after few months temp folders again got disappeared. We are not able to find root cause and permanent fix for this issue. It seems search service got corrupted and need to rebuild again. Does anyone has faced this issue. I don’t prefer rebuilding the search application as this issue is on Production server. Please let me know your views.
