A superesportiva YZF-R1, icone em motocicleta superesportiva, chega em sua versão 2010 a rede de concessionarios autorizados

 

Se não fosse pelos faróis, retrovisores e outros equipamentos exigidos por lei para que o modelo 2010 da consagrada Yamaha YZF-R1 possa rodar nas ruas, poderia facilmente ser confundida com a Yamaha YZR-M1 pilotada por Valentino Rossi na MotoGP.

 

Pode parecer que você já leu essa história antes, mas realmente essa nova R1 traz para as ruas inovações e tecnologias antes vistos somente em motos de corrida. Nova dos "pés a cabeça", a nova R1 traz um motor ainda mais potente com diversas inovações mecânicas, três mapas eletrônicos de desempenho, embreagem deslizante e um novo quadro de alumínio.

 

Mas sem dúvida a grande novidade da R1 2010 é o propulsor de quatro cilindros em linha, DOHC, com refrigeração líquida que manteve a mesma capacidade cúbica do anterior: 998 cc. Mas as semelhanças com o motor que equipa sua antecessora param por aí. Tudo - do virabrequim ao cabeçote - é novo.

 

Aliás, o virabrequim do tipo "crossplane", como os utilizados nos motores V8, é a grande novidade desta R1. Originário do motor da YZR M1 de Rossi, nesse tipo de virabrequim cada biela está posicionada a 90°. Dessa forma, o intervalo de ignição não sequencial (270°-180°-90°-180°) proporciona um torque ainda mais linear e controlável. Um sentimento único nunca antes experimentado pelos motociclistas. Esse virabrequim crossplane e cada cilindro "explodindo" individualmente são novidades mecânicas inéditas em motos de rua. Com essa tecnologia o torque inercial do motor que compõe o torque máximo da moto é minimizado. Isso faz com que o torque transferido à roda traseira tenha uma relação muito próxima de 1:1 com o torque proveniente da câmara de combustão, controlado pela mão do piloto no acelerador. Isso significa uma entrega de torque mais linear. Proporcionando um controle mais preciso da aceleração.

 

O torque da nova R1 está ligeiramente superior, porém mais constante: agora são 11,8 kgf.m a 10.000 rpm, contra os 11,5 kgf.m do modelo anterior - isso sem a indução direta de ar que atua em altas velocidades. A potência também aumentou timidamente sem a indução de ar. Subiu dos 180 cv anteriores para 182 cv a 12.500 rpm.

 

Outras novidades do modelo 2010 são a adoção de uma embreagem deslizante, bastante útil nas reduções bruscas de marcha antes de contornar curvas, e três mapas de ignição do motor. Utilizado pela primeira vez em uma moto de série da Yamaha, o sistema de escolha de mapeamento do motor, chamado de D-mode Map da Yamaha, oferece três diferentes modos: standard para diversos tipos de pilotagem; modo A para respostas mais esportivas; e o modo B para respostas mais "gentis" do acelerador.

 

Claro que as qualidades do modelo anterior, tais como acelerador eletrônico e dutos de admissão variáveis, também equipam a YZF-R1 2010. Tudo controlado por um moderno módulo eletrônico.

 

Mas as alterações não ficaram apenas no motor. O quadro Deltabox em alumínio também é totalmente diferente do anterior. Além de apresentar um equilíbrio ainda melhor entre rigidez e flexibilidade, ficou mais compacto. Centralizando as massas e reduzindo o centro de gravidade de toda a motocicleta.

 

Suspensões, freios, um pneu traseiro com nova medida 190/55-17 e o até então inédito amortecedor de direção eletrônico foram projetados para melhorar ainda mais essa superesportiva de 1.000cc.

 

Quanto ao design, a Yamaha não houveram mudanças radicais, mas estas são facilmente perceptíveis. A carenagem frontal está mais "pontuda" e com dois canhões de luz. Na traseira, os escapamentos ganharam formas triangulares e a lanterna de LED também tem novo desenho. Além de ela parecer mais compacta.

 

As mudanças no chassi e no motor são as mais significativas nos últimos 11 anos de história da motocicleta - a Yamaha YZF-R1 foi lançada em 1998.

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

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

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

Década de 1980

 

Neste início de década só eram disponíveis os modelos LTD e Landau. Por causa da crise do petróleo, foi lançada a versão movida a álcool, que passou a partir daí a reponder pela maioria das vendas. Neste ano também surge a famosa cor Azul Clássico para o Landau, que dava um toque de classe a mais no carro. Os refletores vermelhos na extremidade das laterais traseiras mudavam e passavam a ser iluminados quando se acendiam as lanternas. Ganhou escapamento duplo e porta-malas com abertura interna.

 

Em 1981 as luzes de marcha-à-ré voltam a ser integradas às lanternas traseiras, desta vez ocupando o lugar aonde até 1980 acendia o terceiro par da meia-luz traseira. O Landau continuou fazendo sucesso, sendo o carro oficial da presidência, de muitas personalidades e da elite brasileira.

Ford Landau 1982

 

No ano de 1982 o LTD deixava de ser fabricado. A única versão disponível é a topo de linha Galaxie Landau.

 

Em 1983 o Galaxie saiu de linha, totalizando 77.850 unidades produzidas em seus 16 anos de luxo. Neste último ano somente 125 unidades foram produzidas. Nesta época, com o agravamento da crise do petróleo, diminuiu a procura pelos sedãs grandes, o que levou a Ford a encerrar a produção deste que foi o mais luxuoso automóvel produzido no Brasil.

 

Em seu lugar foi introduzido o Ford Del Rey, que também fez sucesso, mas nada comparado ao luxo e imponência de um Ford Galaxie.

The C41 chemicals were more depleted than I expected and when I exposed the paper to light it was done while the paper was in the MOD45; you can see the imprints where the 'teeth' held the paper top and bottom of the frame.

 

The frame colours haven't been inverted, this is how it looks.

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
