I learned that the calendar with this written in Hatena Anonymous Diary was deleted, but apparently there are other calendars that have been deleted. I looked it up.
The Advent Calendar page does not have a link to the deleted calendar, so I can't look it up from here, but fortunately there is a list of calendar URLs. I used this because there was a post.
I tried to find out on what day the person who set up the Advent Calendar would enter --Qiita
There are 499 Advent Calendars open to Qiita around 22:00 on Thursday, December 3rd.
That's right.
If you access the URL listed here and it is 404 Not Found, it means that the calendar has been deleted.
I can't check about 500 manually, so I wrote it in Python.
deleted_calendar.py
import re
import requests
import time
def main():
url = "http://qiita.com/sudoyu/items/0a51593b257f419aeb20.md"
print(url)
res = requests.get(url)
print("status code: {}".format(res.status_code))
if res.status_code != 200:
return
r = re.compile("^\* (.+)$")
calendar_urls = [m.group(1) for m in map(r.match, res.text.split("\n")) if m]
deleted_url = []
for idx, url in enumerate(calendar_urls):
time.sleep(0.2)
while True:
print("({:3d}/{:3d}) {} ... ".format(idx, len(calendar_urls), url), end="", flush=True)
status_code = requests.head(url).status_code
print(status_code, flush=True)
if status_code == 404:
deleted_url.append(url)
if status_code in [200, 404]:
break
print("retry...")
time.sleep(30)
print("--------\ndeleted calendars")
for url in deleted_url:
print(url)
if __name__ == "__main__":
main()
18 deleted calendars were found. I looked up the calendar name from the cache of Google search.
--Engineer who can't girlfriend (advent-calendar / 2016 / give_me_kareshi)
If you do a Google search for the character string in parentheses, it will appear at the top, so you can check the contents before deletion in the cache of ▼. Even if the calendar is deleted, the linked posts and blogs seem to remain as they are.
mainly
Qiita is a service for recording and sharing programming knowledge.
It seems that the calendar that does not meet the policy has been deleted.
Neta-types such as "Muscle" and "Kareshi Kanojo" were popular in the subscription ranking, but most of the posts are irrelevant to programming, so it is natural that they will be deleted.
In addition, it seems that the calendars related to engineers such as "Freelance Cruel Story" and "Change of Job" that were judged not to be related to programming were deleted. However, the judgment criteria around here seem to be about, and there are many similar themes that remain without being deleted.
There is also a calendar of the company that caused the problem, but I wonder if this was deleted voluntarily.
