As described in sort documentation it's supposed to return a sorted sequence of the items in collection.
Why it properly sorts [3 1 2 4] but is unable to sort [2010 2014 2018] in ascending order?

UPDATE: it was a typo (1014 instead of 2014) as was pointed in answer.
Looks like you have a typo:
(sort [2010 2014 2018])
2014 instead of 1014.

This is somewhat of a continuation of a previous post but I am trying to forecast weekly revenues. My program seems to hang on the adfuller test. It has run before and appears stationary via p-value but not consistently. I have added SARIMAX in as well and the code just hangs. If I cancel out I get a message towards the bottom (periodically) that says the problem is unconstrained.
Data:
Week | Week_Start_Date |Amount |year
Week 1 2018-01-01 42920 2018
Week 2 2018-01-08 37772 2018
Week 3 2018-01-15 41076 2018
Week 4 2018-01-22 38431 2018
Week 5 2018-01-29 101676 2018
Code:
x = organic_search.groupby('Week_Start_Date').Amount.sum()
# Augmented Dickey-Fuller test
ad_fuller_result = adfuller(x)
print(f'ADF Statistic: {ad_fuller_result[0]}')
print(f'p-value: {ad_fuller_result[1]}')
# SARIMA Model
plt.figure(2)
best_model = SARIMAX(x, order=(2, 1, 1), seasonal_order=(2, 1, 1, 52)).fit(dis=1)
print(best_model.summary())
best_model.plot_diagnostics(figsize=(15,12))
I am only working with 185 or so rows. I don't understand why code is just hanging. Any optimization suggestions welcome (for adfuller and SARIMAX).
Fixed via passing organic_search['Amount'] instead of organic_search.groupby('Week_Start_Date').Amount.sum()
I am new to ETL and I was assigned with a task on sanitizing some sensitive information before giving the data to a client.
I am using HUE web client with Impala.
What I want to do is:
For example, a column info like '京客隆（三里屯店）', then I need to transform it into something like '京XXX店）' .
My query is:
select '京客隆（三里屯店）', concat(substr('京客隆（三里屯店）', 1, 3), 'XXX', substr('京客隆（三里屯店）', char_length('京客隆（三里屯店）') -6, 6));
But I get gibberish in the output:
'京客隆（三里屯店）' | concat(substr('京客隆（三里屯店）', 1, 3), 'xxx', substr('京客隆（三里屯店）', char_length('京客隆（三里屯店）') - 6, 6))
京客隆（三里屯店） | 京XXX�店�
The problem is that :
select '京客隆（三里屯店）', substr('京客隆（三里屯店）', char_length('京客隆（三里屯店）') -3 , 3);
output: 京客隆（三里屯店） ��
doesn't get the correct characaters. Why is that? I pasted the string in python shell and I can get the correct characters if I only take the last 3 bytes.
It turns out that I misunderstood the function substr.
substr(STRING a, INT start [, INT len]) :
It takes characters starting from (including) INT start. So for example my string '京客隆（三里屯店）' is 27 bytes long in total, and each utf8 char takes 3 bytes here. I need to take the last 3 bytes, which is the ） , then I need to write:
substr('京客隆（三里屯店）, 27 - 2 ,3 ) .
It then gets the 25, 26, 27 3 bytes and display the char ） correctly.
Updated:
I was told to use :
SELECT regexp_replace('京客隆（三里屯店）', '(.)(.*)(.{2})', '\\1***\\3');
works like an charm :P.
I´m just running the following example from GGEBiplotGUI package and of course, it works properly.
library(GGEBiplotGUI)
data("Ontario")
Ontario
GGEBiplot(Data = Ontario)
But when I download "Ontario" data and I want to run the above cited script on my PC. See the example below.
Ontario <- read.csv("Book.csv")
library(GGEBiplotGUI)
GGEBiplot(Data = Ontario)
The result is the following table (from column 0 to 10) taking numbers (From 1 to 17) as genotypes and "X" as another location.
See the result below please.

How can I fix this problem? I mean, in order to avoid "rownames" and "x" as a variables in the GGEBiplotGUI analysis.
I have also tried with these codes and they didn´t work:
attributes(Ontario)$row.names <- NULL
print(Ontario, row.names = F)
row.names(Ontario) <- NULL
Ontario[, -1] ## It deletes the first column not the 0 one.
Many thanks in advance!
This code worked properly.
Ontario <- read.csv("Libro.csv")
rownames(Ontario)<-Ontario$X
Ontario1<-Ontario[,-1]
library(GGEBiplotGUI)
GGEBiplot(Data = Ontario)
I am using Ruby v2.2.3 on Windows 10.
I want to find out who created and who last modified a given file. Is there a way to do this using Ruby?
I don't have access to Windows, but at least on OSX (and I'd assume unix-lik OS's) File.stat and Etc.getpwuid will get you what you want.

I have an object Report that contains two integer fields: Month and Year.
I need to sort it by "date"
Report.desc(:year).desc(:month).each do |a|
puts a.year.to_s + " " + a.month.to_s
end
results:
2011 12
2011 11
2012 7
2012 6
2012 5
2012 4
2012 3
2012 2
2012 1
While I would think to get
2012 7
2012 6
2012 5
2012 4
2012 3
2012 2
2012 1
2011 12
2011 11
What am I doing wrong?
The Mongoid Criteria looks like:
irb(main):043:0> Report.desc(:year).desc(:month)
=> #<Mongoid::Criteria
selector: {},
options: {:sort=>{"year"=>-1, "month"=>-1}},
class: Report,
embedded: true>
The result you get is only sorted by month not by the whole date(thus the result you get). Maybe use the sort_by method with a body that takes into account both the year and the month?
Something like:
Report.sort_by{|t| [-t.year, -t.month]}
EDIT: I am using the negatives of both the year and the month to achieve decreasing order.
