eclipse can not detect the wrong functions

Today, when I use php function "fputs" and I made a typo as "fput", and did not get an red cross for this wrongly usage, I thought I hit a bug in the eclipse php error detection plug-in. After searching for 30 mins, I found no people talking about this. And after a test, I found, seems misspelling standard functions in php is actually not an "error", though I thought it should be. I think that is because functions can be customized, like class. Thought seems it is simple, but I still think it is a good idea to add the typo error to the standards functions.

install ipython in Cloudera VM using pip

I am practicing pyspark in Cloudera VM, and pyspack need be launched by ipython. In all the old Cloudera VM guide, it use easy_install to install ipython, but it does not work in Virtualbox 5.2.0 r118431 and later. And will get the error : $sudo easy_install ipython==1.2.1 ... error: Could not find suitable distribution for Requirement.parse('ipython==1.2.1') The solution for this is to use pip to install ipython. But by default, pip is not installed in cloudera VM, and pip can not be installed by eacy_install as well. And after some search, I  noticed cloudera has yum installed, and yum can install pip: $sudo yum install python-pip ... $which pip /usr/bin/pip Now ipython can be installed b pip: $sudo pip install ipython=1.2.1 ... Succesfully installled ipython-1.2.1 After that, launch spack by ipython: $PYSPARK_DRIVER_PYTHON=ipython pyspark ...

When following the Install PostgreSQL in Ubuntu  in Ubuntu 16.04, got error as below: $ apt-get install postgresql-9.6 Reading package lists...

timestamp with 16, 13 and 10 digits to Qlik date

Sometimes, we need to convert the Linux timestamps to Qlik date, it can be done in the SQL script, and can also be done in the Qlik Load/expression. Linux timestamps with 16 digits are microseconds timestamps, and 13 digits are milliseconds, and 10 digits are second timestamps. To convert to a Qlik date, hour or time as following: As the timestamps starts from "19700101 00:00:00",  then this start timestamps needs be added: For 16 digits: Date(Date#('19700101', 'YYYYMMDD')+(SynchronousQuery_ Event_Time/1000000/86400) or  Date(25569+Round(SynchronousQuery_ Event_Time/1000000/86400),'YYYYMMDD') 25569 is the number format for date '19700101' For 13 digits: Date(Date#('19700101', 'YYYYMMDD')+(SynchronousQuery_ Event_Time/1000/86400) or  Date(25569+Round(SynchronousQuery_ Event_Time/1000/86400),'YYYYMMDD') For 10 digits: Date(Date#('19700101', 'YYYYMMDD')+(SynchronousQuery_ Event_T
