Jeżeli nie wiesz, gdzie udać się na kurs javascript - najlepszą decyzją będzie szkoła IT, Coders Lab. Wysoki poziom kształcenia, ciekawe zajęcia oparte głównie na praktyce, oraz wykwalifikowani wykładowcy, działający w fachu. To właśnie jest droga do sukcesu!

This is animated similar to a waterfall. The images fall down the page. This was programmed using the Prototype and Scriptaculous javascript libraries.

When running this test via Yeti on Windows multiple #stats and #report elements are added to the #mocha element.

This is based on the original game's "Level 9" battlefield layout.

On the TODO list: Upgrading the enemy AI to be tougher including firing heat-seeking missiles at your chopper, dropping infantry on your bunkers / super bunkers, and other offensive strategies.

So, I've been a bad flickr person. I take a long time to respond to comments, I rarely comment on other peoples streams. In general, I suck. However, I have been ruling my job lately.

This is the SproutCore team at MobileMe, to whom I am an engineering project manager (one of my teams). We just hosted our first day (of two) of company wide training where people were flown in from the far corners of the earth to learn our sweet-ass web platform framework. It went swimmingly, and I am super pleased. I'm in the back, because 'I got their backs, yo'.

I set up this shot, and Ramiro (who is awesome) pulled the trigger for me. Faruk (also lovely) was kind enough to play human light stand.

Strobist info: Nikon SB900 on 1/2 power, bouncing through a 43" umbrella, hand held by Faruk, in front of team in the middle, about 2ft above our heads and 2ft to the front.

Jeremy's presentation was a big hit. I really enjoyed it. Mark was kind enough to pull up the slide on his MacBook Pro for me, as I was not fast enough on the trigger to get it when it was on the big screen.

Talking to attendees before the talk. (Crockford on JavaScript, "Scene 6: Loopage"; Yahoo! HQ, Sunnyvale, CA, August 27, 2010.)

Screenshot of a javacript page I've been playing with. It shows the colors of the "named" colors (from css and/or "x11" colors) sorted by various methods.

No promises the math is correct. Or that the code is any good. I don't really know what I'm doing.

ZoomCharts at DevClub.lv: Developing a Javascript SDK

On January 15, 2015, ZoomCharts Co-Founder and CTO Viesturs Zariņš presented at DevClub.lv - a community of Latvian IT specialists that gather monthly and host free talks, presentations, and events to allow the local IT community to share knowledge, network, and communicate. Zariņš discussed the unique challenges faced in developing JavaScript SDK.

Here is a brief overview of his PowerPoint presentation on ZoomCharts, the world’s most interactive data visualization software that will support all your data presentation needs with incredible speed.

What is ZoomCharts?

What defines ZoomCharts advanced data visualization software? It is NOT another HTML5 charts library. It is:

- Interactive

- Fast

- Touch enabled

- Supports big data

A long time ago

DOS 6.2 allowed for:

- 320x240x8bpp

- Direct access to pixels on screen

- Assembler for performance

Today, the Web has finally caught up in the graphics department. Now, we have access to:

- Multiple browsers and rendering technologies

- Multiple resolutions

- Performance that varies by browser and device

Development setup:

- We write in JavaScript

- Commit to GitHub

- Build system in JavaScript

- Debug in Chrome

- Run automated tests

- Like WebStorm (and Vim)

Graphics:

Canvas (fast)

SVG (slow)

WebGL (>50%)

Interactive animations:

Zoom in and out of the graph, drag and drop data, all with your mouse or trackpad.

Graceful degradation:

High FPS (frames per second) lets you scale graphics with low image degradation.

Third party libraries:

- Raphael

- Hammer.js

- Leaflet

- Moment.js

Challenges:

- Responsive design: layouts can shift and look nice on desktop screens vs. not so nice on vertical, mobile screens

- Big screen resolutions: uses devicePixelRatio for sharp rendering, but no hardware acceleration beyond 2048x2048

- Safari compatibility: with 100% CPU, input events are blocked and browser locks up; strange code offers fixes

- HTML on canvas: DOM is slow; basic HTML markup must be parsed and rendered manually; text caching helps

Support:

- Process: TrialSupportBuy

- 1 day issue resolution

- #1 Tell me what I did wrong

- #2 Can you do…

Testing:

- Automated tests on every GIT push

Automatically:

- Compare images

- Record performance

- View errors in console

Interactive testing:

- Next step: record and playback

BrowserStack:

- Interactive mode

- Automated: Selenium API

Debugging:

Chrome Developer tools (F12)

- Debugging

- Profiling

- Timeline

Remote debugging available: developer.chrome.com/devtools/docs/remote-debugging

Future:

- More charts

- Extension API

- Memory allocation tracking

- WebGL

We are looking for statically-typed language:

- Error checking

- Performance

- Superior minification

- Easy to write and read

- Easy to call from JS

Building

Custom build script:

- Compile

- Minify

- Extract documentation

- Embed customer data

This type of annotations is called tag. These tags have 45° or 255° angle. Could be any. :)

Other people have created games in a canvas. This an extreme example where somebody wrote a JavaScript emulator for the original Space Invaders runtime engine.
