execution - Crontab keeps running -


i have following cronjob (crontab) running on amazon ec2 server linux ami:

*/20 8-22 * * * php -q /var/www/html/xxx.php

unfortunately, script keeps executing every 20 minutes after 23.00 hour. explain i'm doing wrong?

there's nothing wrong syntax. wrote it, job should execute 45 times every day, first being @ 8:00 , last being @ 22:40.

i have hunch problem timezone-related: when job runs @ 23:00, cron thinks local time 22:00. if i'm right, job won't running @ 8:00 start @ 9:00 or later time.

you might able confirm setting job like

* * * * * date >> /tmp/cron.date.test

wait minute see if date in file agrees idea of time is. isn't perfect test because date making own determination of timezone separately cron, inherit environment cron they'll agree each other.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
