Composer is very useful tool or better dependency manager for PHP. Matthieu Moquet wrote excellent blog post about 5 features to know, and I am sure there is more about Composer on his blog posts.
Here is summary of the command line examples, learn to know, what they do:

$ composer update foo/bar
$ composer update nothing
$ composer update --lock
$ composer require "foo/bar:1.0.0"
$ composer init --require=foo/bar:1.0.0 -n
$ composer create-project doctrine/orm path 2.2.0
$ composer init --require="twig/twig:1.*" -n --profile
$ composer update symfony/yaml --prefer-source
$ composer status -v
$ composer update
$ composer dump-autoload --optimize

Hibernate is great piece of java software, which utilize concept ORM – Object Relational Mapping. If application needs to store data into relational database, it simplifies development tremendously. One don’t need to use SQL queries, unless needs to do something very special. Hibernate has drivers supporting all major databases, so it’s easy to switch database. There are plenty of resources, including youtube tutorials, like JavaBrains. There is also Hibernate OGM (Object/Grid Mapper), which provides Java Persistence (JPA) for NoSQL data.

Playing with nette php framework, here is www/.htaccess file, which is working on 1and1 linux platform:
AddType x-mapp-php5 .php
Options +MultiViews

# enable gzip compression
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript text/javascript application/javascript application/json

Here are steps to create bootable USB Flash disk with Windows7.

1. 4GB or bigger USB Flash Disk needed

2. Put your Window 7 Instalation DVD into your computer DVD mechanics. If DVD is not readily available, you may download ISO image, for example, Windows 7 Home Premium x64 with SP1 (bootable) from http://msft.digitalrivercontent.net/win/X17-24209.iso and burn new DVD.

3. On your Windows 7 computer (with DVD in D: and USB Flash in E:) do:

C:> DISKPART
DISKPART>list disk
DISKPART>select disk N
DISKPART>clean
DISKPART>create partition primary
DISKPART>active
DISKPART>format fs=ntfs
DISKPART>assign //letter drive e.g. E:
DISKPART>exit
C:>D:
D:>cd boot
D:>bootsect /nt60 E:
D:>xcopy D:\* E: /E

4. May sure in BIOS, that computer is able to boot from USB Flash drive. It’s also handy to have picture of computer MS Windows certificate.

I was having once a while connection problem with two computers, both with Windows 7 operating system. I found possible explanation and solution, maybe: Windows 7 itself, or more precise Computer Browser Service. Detail description is in excellent article Wireless network drop connection or at Tom’s Hardware forum Randomly losing internet connection.

One should studied more often logs under Administrative Tools -> Event Viewer -> Windows Logs -> System
Solution involves disabling  Computer Browser Service.

Performance of nowadays personal computers is more, than one would expect. They can even run two or more computers in the same time, actually virtual computers, which can share resources of real physical computer. For users of Windows there are several options, one of them is VM VirtualBox from Oracle, under GNU General Public License (GPL) version 2.
For example for small work, it’s possible to create 8GB virtual hard drive, to place ISO image, let’s say Ubuntu Desktop 13.04 (Raring Ringtail) into DVD virtual drive, and install it into virtual hard drive. Don’t forget about sudo -s for root session. With Guests Applications it can even share (network) folders. Command could be for example like
mount -t vboxsf   S_DRIVE /home/joedoe/sdrive/ , if you share network drive S:. Thus is very easy to cooperate and share data between Windows and Linux.
