Why is Magento so slow? [closed]
...ely want to try. If you have a EE version, you can get the Full page up in order to get the best of the beast.
A reverse proxy will also help a lot. It'll cache the static ressources, significantly lowering the pressure on the php interpretation stack of your front servers.

Creating a config file in PHP
...rge PHP applications. However you will likely need to solve the problem in order to find the PHP code which gets incorporated / re-used at runtime.
Common approaches to this are to always use relative directories, or to search from the current directory upwards to find a file exclusively named in t...
Postgres DB Size Command
...g_size_pretty(pg_database_size(t1.datname)) as db_size
from pg_database t1
order by pg_database_size(t1.datname) desc;
If you intend the output to be consumed by a machine instead of a human, you can cut the pg_size_pretty() function.

What is the difference between a var and val definition in Scala?
...a number out of them. For example, if I have a queue with 2, 1, 3, in that order, I want to get back the number 213. Let's first solve it with a mutable.Queue:
def toNum(q: scala.collection.mutable.Queue[Int]) = {
var num = 0
while (!q.isEmpty) {
num *= 10
num += q.dequeue
}
num
}

Do you (really) write exception safe code? [closed]
... of analysis in mind.
The lowest guarantee offered is basic, but then, the ordering of each instruction makes the whole function "none", because if 3. throws, x will leak.
The first thing to do would be to make the function "basic", that is putting x in a smart pointer until it is safely owned by th...
How do I force Postgres to use a particular index?
...
I even had to set random_page_cost = 0.1 in order to make index scan work on large (~600M rows table) in Pg 10.1 on Ubuntu. Without the tweak, seq scan (despite being parallel) was taking 12 mins (Note that Analyze table was performed!). Drive is SSD. After the tweak,...
How to make modal dialog in WPF?
...wDialog()!". But that is the method (not .Show()) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.
First, you need 2 WPF windows. (One will be calling the other.)
From the first window, let's say that was c...
how to File.listFiles in alphabetical order?
...
The listFiles method, with or without a filter does not guarantee any order.
It does, however, return an array, which you can sort with Arrays.sort().
File[] files = XMLDirectory.listFiles(filter_xml_files);
Arrays.sort(files);
for(File _xml_file : files) {
...
}
This works because File...
Adding multiple columns AFTER a specific column in MySQL
...pend to the table.
E.g: if you want to add count, log, status in the exact order after lastname, then the syntax would actually be:
ALTER TABLE users
ADD COLUMN log VARCHAR(12) NOT NULL AFTER lastname,
ADD COLUMN status INT(10) UNSIGNED NOT NULL AFTER lastname,
ADD COLUMN count SMALLINT(...
What is the preferred syntax for defining enums in JavaScript?
... some assumptions can no longer be made (that value represents the correct order for the size for example).
Remember, in JavaScript an object is just like a map or hash table. A set of name-value pairs. You can loop through them or otherwise manipulate them without knowing much about them in advan...
