On "New MIT Code Makes Web Pages Load 34 Percent Faster in Any Browser"

I would like to share some server side solutions that can speed up page and resource loading

https://github.com/galan/packtag - Have used this in Struts before and it does make a big difference

https://jawr.java.net/ -  Has Spring integration and seems really nice. A good starting point is showned on : http://memorynotfound.com/jawr-combine-minify-compress-javascript-css/

For .Net

With Apache/NGINX it is possible to develop a similar approach

RPCS3 + Ubuntu

This weekend i had some time to play around with a emulator ( RPCS3)  on my Ubuntu box.
After installing bison and libedit-dev and fiddling around with LD_LIBRARY_PATH i got it to build

What i don't understand is why i had to do"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu/" considering on "/etc/ld.so.conf.d/"   when there was already a conf file with that path. Permissions issue perhaps? Can someone with more Ubuntu experience shed some light?
Now to the fun part of fidding with Asmjit and LLVM.

Quartz Scheduler

A while back i had to work with Quartz (the scheduler) - Quartz - not to be confused with - Quartz (graphics_layer)  and i would like to share a website that helped me CronMaker.
Thanks to who had the work of making my life easier :)

Struts 2 and TLD issues.

According to TLD or attribute directive in tag file, attribute value does not accept any expressions

I have been rather plagued by this error on the last few days when using Struts2 till. By chance i came across https://almeidamike.wordpress.com/2010/03/12/struts-solving-according-to-tld-or-attribute-directive-in-tag-file-attribute-value-does-not-accept-any-expressions/ .
So if you are having some difficulties accessing parameters of the request or other values be sure to enable debug as specified in https://struts.apache.org/docs/debugging-struts.html and find the correct path to your value.

Examples:
${someField} becomes %{#attr.someField}. Acessing request parameters would be for instance  %{#parameters.someField}.

New job new life new projects.

It seems i have left this place a bit scarse on news for a while now. Starting a new job and getting used to new routines made me neglect this place a bit.
That does not mean i have not been busy :) :

• Working on Spring + JPA + AOP and learning how to deal with some strange errors (if you follow this blog and wish some tutorials and/or to get around common errors please let me know)
• A project i have started in between jobs, leveraging odoo to implement tracking of e-procurement contracts (adapted to the Portuguese reality as that is the one i am more familiarized with) . Connecting those with Odoo projects allows for some really nice features ( https://www.odoo.com/page/project-management. ). 
• Working with my good friends at https://www.linkedin.com/company/good-omens-webstudio (if you do work in Morocco do check them out, they are great at what they do).
• Uploading "Templo dos Jogos" to the Youtube (https://www.youtube.com/channel/UC3QNejga3cw69-NvmFvjyWA/videos )

On a side topic, are there any UK citizens following this blog? I have received some jobs offers from the U.K and i do have a passion for that country, more than for my own country Portugal sometimes (and god knows how it is decreasing), so moving to the  U.K would be a long time project with hopefully citizenship involved. How is it like to be an UK citizen?

Sometimes it is better to have less.

My friends at Good Omens WebStudio shared with me a project that came across them for the Quercus organization. I did a quick analysis of the slow points for them. It didn't take long to do an "oh god".

 The worst is not even shown on that picture:- A 1.6 megabytes ttf font used by one of the css files.
To make matters worse the way Apache is configured the font is never cached by the browser, and it can only start working when it has the font.

One of those things

After installing Odoo like said on the link (http://www.theopensourcerer.com/2014/09/how-to-install-openerp-odoo-8-on-ubuntu-server-14-04-lts/ ) i posted a few messages back.
I noticed a strange behaviour, , massive memory comsuption and cpu usage, on accounts-daemon on my ubuntu 15.04 instalation.
You can attach gdb to a running process by using --pid. So by using

1	sudo gdb --pid=597

I could debug the running process, and then i saw :
