.... Postgres may need to consider more rows than the limit anyway (like with ORDER BY something while it can't use an index, or with aggregate functions). Apart from that, only the limited number of rows from the subquery is processed. – Erwin Brandstetter Jun 17...

... I read a whole article looking for an answer to the init order of initializers vs. their constructors. I didn't find it, so I wrote some code to check my understanding. I thought I would add this little demonstration as a comment. To test your understanding, see if you can predi...

... and it might have the following methods (parameters are not shown): BuildOrderHeaderRow() BuildLineItemSubHeaderRow() BuildOrderRow() BuildLineItemSubRow() This builder would then spit out the HTML for me. This is much easier to read than walking through a large procedural method. Check out Bui...

...entation, directives are structures you can write that angularjs parses in order to create objects and behaviors.In other words it's a template in which you use mix of any arbitrary nodes and pseudo-javascript and placeholders for data to express intentions of how your widget (component) is structur...

...ating over them backwards (so deleting elements doesn't screw up iteration order). To get the indices you need to access the input array by name, which can be done via bash variable indirection x=1; varname=x; echo ${!varname} # prints "1". You can't access arrays by name like aryname=a; echo "${$a...

I work with Series and DataFrames on the terminal a lot. The default __repr__ for a Series returns a reduced sample, with some head and tail values, but the rest missing. ...

... In C++11, you can do std::is_pod<MyType>() to tell whether MyType is POD. – allyourcode Mar 31 '14 at 21:24 7 ...

... You need to count the number of rows: row_count = sum(1 for row in fileObject) # fileObject is your csv.reader Using sum() with a generator expression makes for an efficient counter, avoiding storing the whole file in memory. If you already read 2 rows to start ...
