## Add/assign same Five Star rating to author while adding to Article using Rules

I Need to achieve this functionality only with Rules or combinations with any other module(s).

Structure

FiveStar field is attached to the node type Article and another with the User profile.

Requirement

When an user add rating for the Article it should apply the same rating for its author. The rating of the author on his profile must be functional as a regular rating i.e. the user can receive multiple ratings and an average is shown.

I have tried with the below Rules:

{ "rules_author_rating" : {   "LABEL" : "Author Rating",   "PLUGIN" : "reaction rule",   "OWNER" : "rules",   "REQUIRES" : [ "rules", "voting_rules" ],   "ON" : { "voting_rules_insert_node" : [] },   "IF" : [     { "node_is_of_type" : { "node" : [ "node" ], "type" : { "value" : { "article" : "article" } } } }   ],   "DO" : [     { "data_set" : {         "data" : [ "node:author:field-author-rating" ],         "value" : [ "node:field-node-rating" ]       }     }   ] } 

}

But it logs an error

Unable to modify data “node:author:field-my-rating”: Invalid data value given. Be sure it matches the required data type and format. Value at node(3)->author->field_author_rating: 80.

## [ Safety ] Open Question : Now that this is the second Boeing 737 Max 8 jetliner crash shortly after take off in five months, is there a design flaw or no?

And should all Boeing 737 Max 8 jetliners be grounded ? The Ethiopian Airlines jet that crashed shortly after takeoff on Sunday, killing all 157 people aboard, is the same make and model as the plane that crashed off Indonesia last year with 189 deaths Officials lost contact with Flight 302, a Boeing 737 Max 8 jetliner flying from Addis Ababa, the Ethiopian capital, to Nairobi, the Kenyan capital, at 8:44 a.m. (1:44 a.m. ET), authorities said. That was about six minutes after the plane took off from Bole International Airport, they said. Tewolde GebreMariam, the airline’s chief executive, said that the captain reported “difficulties” and asked to return to the airport but that then the plane “was lost from the radar — it disappeared.” The Ethiopian Airlines jet had been in service for only four months and had no known technical issues, GebreMariam said. In late October, Lion Air Flight JT610 — also a Boeing 737 Max 8, which had been in service for only 2½ months — crashed into the sea shortly after takeoff from Jakarta, the Indonesian capital. Indonesian authorities said that contact with Flight JT610 was lost after 13 minutes and that the captain reported a “flight control problem.” Pilots flying the same plane a day earlier had experienced a similar problem, authorities said.

## Why can’t I have more than five browsers and/or apps up on my phone at once?

On my LG phone, if I try to bring up a sixth app/browser/whatever, it automatically deletes one that is already up. But other people on my plan, with the exact same phone, can have more things up, often many more. Why is that?

## Envelope Question: Five letters addressed to individuals 1,2,3,4 and 5 are randomly placed in five addressed envelopes, one letter in each envelope.

I’m trying to find the probability of:

1. Exactly three letters go in the correct envelopes.
2. Exactly two letters go in the correct envelopes
3. No letters go in the correct envelopes

Here is my approach:

So there is clearly a total of 5! distinct ways of arranging the letters.

1. If exactly three letters go in the correct envelopes, then there are $$5 \choose 3$$ ways of choosing the positions for the three correct envelopes, and for the remaining two letters, there are 2! ways of organizing them. Thus, probability = $$\frac{{5 \choose 3} * 2!}{5!}$$.

2. If exactly two letters go in the correct envelopes, then there are $$5 \choose 2$$ ways of choosing the positions for the two correct envelopes, and for the remaining three letters, there are 3! ways of organizing them. Thus, probability = $$\frac{{5 \choose 2} * 3!}{5!}$$.

3. I’m not really sure how to approach this problem.

Any input would be great.

## Five functions to get the digits of a number

I’m writing a simple function: given a number, it will return a sequence or a collection of the digits in the number (in the correct order). i.e (get-digits-fn 1234567) => (1 2 3 4 5 6 7) / [1 2 3 4 5 6 7]

Below are five attempts at the same function:

(defn get-digits-1 [num]   (->> [num '()]        (iterate (fn [[num digits]]                   (when (> num 0)                     [(quot num 10) (conj digits (rem num 10))])))        (take-while some?)        (last)        (second)))  (defn get-digits-2 [num]   (when (> num 0)     (lazy-seq (concat (get-digits-2 (quot num 10)) '((rem num 10))))))  ;; Suggested by Carcigenate (defn get-digits-3 [num]   (->> (str)        (map str)        (map int)        (into '())))  (defn get-digits-4 [num]   (loop [n num          res '()]     (if (= n 0)       res       (recur (quot n 10) (conj res (rem n 10))))))  (defn get-digits-5 [num]   (->>    (iterate (fn [[n digits]]               [(quot n 10) (conj digits (rem n 10))])             [num '()])    (drop-while #(not= 0 (first %)))    (first)    (second))) 

A helper function for testing performance:

(defn quick-bench-get-digits [fn range]   (quick-bench (->> range                     (map fn)                     (map (partial apply vector))                     (into [])))) 

The perf results (output truncated to only show execution time mean):

eul> (quick-bench-get-digits get-digits-1 (range 1 100000)) Execution time mean : 129.516521 ms  eul> (quick-bench-get-digits get-digits-2 (range 1 100000)) Execution time mean : 128.637055 ms  eul> (quick-bench-get-digits get-digits-3 (range 1 100000)) Execution time mean : 24.267716 ms  eul> (quick-bench-get-digits get-digits-4 (range 1 100000)) Execution time mean : 25.083393 ms  eul> (quick-bench-get-digits get-digits-5 (range 1 100000)) Execution time mean : 145.430443 ms 

It looks like get-digits-3 is the fastest while get-digits-4 is closely behind. (As the numbers increase, get-digits-3 outperforms get-digits-4. i.e try (range 1000000 2000000)`)

1. Any way to increase performance more without leaving Clojure land?
2. If mutability and Java inter-op is allowed, is there a way to increase performance?

p.s. functions 1 and 5 are almost identical. This was incremental exploration.

## AWS Autoscaling Group won’t honor five minute draining policy of the Target Group when scaling down

We have an Autoscaling Group in AWS that we manually scale up and down at the time being. Our ASG is currently attached to one Target Group, which has all of our prod servers in it.

Before using the ASG, we would add and remove servers to the Target Groups manually from the Target Group console, and the nodes would deregister after draining properly. We have a very stateful application so the deregistration delay is really important for us.

Yesterday when scaling down through the ASG interface (specifically by asking for a lower number of desired instances), all the connections dropped instantly, which dropped hundreds of connections instantly instead of honoring the five minute draining policy of the target group.

How do I make my ASG honor my draining policy?

I have tried this: AWS ASG With Application LB and Connection Draining but it does not set the connections to “draining”, but just “terminating: waiting”, and my health checks are healthy so I don’t think it is actually stopping new connections/draining.
