Reading “First Spring” by Stefan Żeromski for my Polish literature classes. I’ve just finished reading the first part and - honestly - I still don’t know what to think about it, about Cezary.

He seems to have his own point of view about the world but doesn’t show it, so in final result - we don’t know exactly what he has in his mind.

But time will show… I hope 😛

Database performance

I created very simple M:N relation between batches and ISISNs. Each Batch could contain up to the 1000 ISISNs.

Here are some statistics:

Very fisrt run

SQL Server parse and compile time:
  CPU time = 0 ms, elapsed time = 6 ms.(2 rows affected) SQL Server Execution Times:
  CPU time = 10077 ms,  elapsed time = 4012 ms.
SQL Server parse and compile time:
  CPU time = 0 ms, elapsed time = 0 ms.

Next run

SQL Server parse and compile time:
  CPU time = 0 ms, elapsed time = 0 ms.(2 rows affected) SQL Server Execution Times:
  CPU time = 8921 ms,  elapsed time = 2428 ms.
SQL Server parse and compile time:
  CPU time = 0 ms, elapsed time = 0 ms.

Join with four batches


In this tutorial, I show how you can read multiple checked checkboxes values and save to MySQL database and fetch it with PHP.


In this tutorial, I show how you can send JavaScript Array as data in the AJAX request and handle it with jQuery and PHP.

[6/100] Deep stuff

Today and few days before, I tried to setup my environment on Linux. I had some problems … I tried to run Oracle DB, but I had too low swap area. There was necessary ~7GB and I had 4. And I really did not want to reinstall whole system for the 5th time this year. So I posted an article on Stack Overflow. I tagged it with hashtags Oracle, Linux, etc. First comment solved the issue, but few hours later some Oracle guy send me comment that it is not relevant to Oracle, but disk management. So I explained that I am opened to any advice e.g. that DB can be installed with some trick. He admitted that it is good argument and recommend to edit the text slightly - so I did. Next day 3 people from Oracle down voted the question that it is not relevant to development and my question was removed. What a mafia. Anyway that kind dude who replied at first place recommend to use booting tool gparted to extend swap partition. Seems it is working and resizing is in progress, so I will see. :-)

SSRS - How to Create Recursive Report

In Reporting Services paginated reports, a recursive hierarchy group organizes data from a single report dataset that includes multiple hierarchical levels, such as the report-to structure for manager-employee relationships in an organizational hierarchy.

I swear i need a work buddy to squee over my successes and commiserate my struggles. I’m so excited about finally figuring out what was wrong, but like it’s expected too. It’s my job to be able to do this. And when i hand it over to my boss, he won’t know the days of struggling that went into making it run.

I’m nearly finished writing a code to pick up membership, claims costs, and prescription counts for one line of business, but it won’t run! It’s a query made of 9 sub queries, 7 of which do run. I run out of spool space on the 8th query, and i don’t know how to fix it. I hate spool space errors!
