Tributary - live and responsive visual coding

2012-05-09T08:19:00.001+02:00

As in the blog post: http://enja.org/2012/05/07/floating-down-a-tributary/

Tributary is a web interface for live and responsive visual coding. It includes a code editor and provides some popular javascript libraries for visual programming. The core concept of tributary comes from the inspirational Bret Victor video and the implementation is derived from Gabriel Florit’s water project.

See video for yourself:

Project is new but worth a try :)

http://enjalot.com/

To start playing with it just visit one of examples eg. http://enjalot.com/tributary/2271952/squarecircle.js click on value in source code and see how canvas is changing :)

How to design a good API

2012-05-06T12:36:00.000+02:00

Joshua Bloch presentation about designing API and why this is important.

http://lcsd05.cs.tamu.edu/slides/keynote.pdf

I've read only slides but I think that most of talk content is in them, but if you have time try to watch video (or listen to it) and read slides at the same time.

This isn't only about API but much more than that, API is just the beginning.

Cross Browser Extensions

2012-04-25T10:30:00.000+02:00

http://babelext.com/

Project thanks to which creating cross browser extensions can be much easier :)

Thanks to it I've found new project in Mozilla: https://addons.mozilla.org/en-US/developers/builder
With builder extension are similar to Chrome extensions. At least! :-)

There is also another project that tries to do the same thing in different way: http://kangoextensions.com/
Kango is commercial but is free for open-source and non-commercial projects.

WEBSHIMS LIB.

2012-04-10T13:37:00.000+02:00

Interesting project for shim all HTML5 features for old browsers!

This could be for shims like jQuery for JS libraries :) But this is really hard to have both speed and support and in some cases it is just better to prompt user for better browser than trying to display things that will probably slow website to point it can't be used.

This really interests me how long it will take to start and shim especially in old browsers when there is much more to shim.

Node.js Uncanny Lessons

2012-04-04T11:33:00.000+02:00

Interesting presentation about Node.js in practice:

Online REPL

2012-04-04T09:15:00.001+02:00

Repl.it is application that can be used as repl for many languages, especially when you don't have one for that language installed in OS.
Left panel can be used to run multiline code - this is big advantage over standard repl, in that situation usually you need to create file for it or write it in repl that can be tricky.

Kickstrap

2012-04-04T06:42:00.001+02:00

Kickstrap is a project that aim to be more powerful version of Twitter Bootsrap. Something like Bootstrap++ :)

From start it has themes, many JS libraries, h5bp build script...

http://ajkochanowicz.github.com/Kickstrap/index.html

Kickstrap is not yet stable so beware until 1.0!

Schema.org vs. Microformats

2012-04-04T06:38:00.002+02:00

Pretty good FAQ about this standards:

http://www.seomoz.org/blog/the-lowdown-on-structured-data-and-schemaorg-your-questions-answered

Short answer: Schema.org has support of search engines so It has more chances to be de facto standard.

Repair GRUB2 Boot

2012-03-27T20:09:00.002+02:00

After installing Ubuntu next to Linux Mint, Ubuntu started to be default option.

It was annoying :)

I started to search how to deal with GRUB2, but the problem was about installing grub from Mint partition.

The easiest solution is to install Boot Repair: http://sourceforge.net/p/boot-repair/home/Home/

I've found it on Ubuntu forum: http://ubuntuforums.org/showthread.php?t=1769482

I can recommend it, really worked from first try :)

Install in Ubuntu:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update && sudo apt-get install -y boot-repair && boot-repair

My Meet.JS Presentation

2012-03-26T09:01:00.000+02:00

How to Test? Is unit testing really helpful?

My presentation form last Meet.JS: http://goo.gl/u7w61 (in Polish)

Presentation is about Testing, not only about JavaScript, but in general.
I must admit that I was influenced by inventing-on-principle by Bret Victor

Hopefully this presentation encourage people to think about testing as a way to speed up development, not as a cost :-)

If you attended last Meet.JS let me know what you think, I wasn't as good as Bret so I will be glad for comments how to be better :-)

PHP Package Managers

2012-03-26T08:34:00.001+02:00

Today morning I read post about conference 4Developers at: http://blog.kamilbrenk.pl/konferencja-4developers/

What makes me curious are PHP package managers.

I use npm in Node.JS and I'm happy that in PHP exists alternatives.

Packagist is much more like npm and has much more packages.

netbeans.conf - How to make NetBeans faster

2012-03-21T13:37:00.001+01:00

I've started to experimenting with NetBeans again, but for that I need to make NetBeans faster...

Consider adding to your /etc/netbeans.conf minimal and maximal Heap sizes (larger than default).
-J-Xms256m start level
-J-Xmx1024m maximum
Adjust it to your RAM, and current memory usage.

on Windows 7:
netbeans_default_options="-J-client -J-Xss2m -J-Xms128m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Xverify:none -J-Xmx512m -J-XX:CompileThreshold=100 -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled "

Ideas from: http://performance.netbeans.org/howto/jvmswitches/

Beware that on LinuxMint I used only

-J-Xms512 -J-Xmx2048m
without GC and CompileTreshold due to slowdown of IDE and whole system (100% CPU without reason).

The best idea is to experiment and try on your machine.

Furthermore consider disabling as much Plugins as You can. If you are not using svn/hudson/bugzilla just remove it (or at least disable). Disabling Spellcheckers should also gain speed.

Learn WebGL with Erik Moller

2012-03-21T13:22:00.001+01:00

A WebGL instructional video by Erik Moller.

I think that this is awesome opportunity to learn WebGL! Watching video is really easy, and with just that you can learn basics of WebGL.

Of course WebGL is supposed to be low-level API and I suggest to use Library like THREE.js or J3D, but ability to know what this libraries are doing can be really helpful.
