this related another question here . i want create series of cron scripts, cron scripts can have 1 instance each. need implement lock files each script. decided create abstract cron class create lockfile on __init__ , destroy on __del__ . approach has proven incorrect getting unpredictable results __del__ method. it has been requested open new question asking how implement this. best approach here? 1 cron script check email, checks database, , forth. my reasoning behind using cron don't trust myself build monolithic daemon 1 script. can't afford have entire daemon breakdown if 1 unrelated part stops working. perhaps unwarranted fear proper implementation?

using stock android examples httpurlconnection , httpresponsecache, have created bare bones app calls 2 urls, twice. first 1 without content-length , second 1 content-length . i can see in charles endpoint without content-length not cached. removed content-length caching url , confirmed prevents caching well. unfortunately there no way have gzipping , content-length in restify according gzip plugin docs . is there way force httpresponsecache cache url when content-length missing? logic behind not caching urls without content-length? (ios caches without content-length) *using volly or restify last resort due large existing codebase. ended moving retrofit had no issues caching without content-length header.

i'd 'anonymize' or 'recode' column in pandas dataframe. what's efficient way so? wrote following, seems there's built-in function or better way. dataset = dataset.sample(frac=1).reset_index(drop=false) # reorders dataframe randomly (helps anonymization, since order have meaning) # make dictionary of old , new values value_replacer = 1 values_dict = {} unique_val in dataset[var].unique(): values_dict[unique_val] = value_replacer value_replacer += 1 # replace old values new k, v in values_dict.items(): dataset[var].replace(to_replace=k, value=v, inplace=true) iiuc want factorize values: dataset[var] = pd.factorize(dataset[var])[0] + 1 demo: in [2]: df out[2]: col 0 aaa 1 aaa 2 bbb 3 ccc 4 ddd 5 bbb in [3]: df['col'] = pd.factorize(df['col'])[0] + 1 in [4]: df out[4]: col 0 1 1 1 2 2 3 3 4 4 5 2
