Confused About Map/Reduce?

 

 I was working on some Hadoop stuff recently, and as a total beginner, I found that the Map/Reduce concept was not easy to understand, despite the huge number of tutorials.
The Wordcount example is the ‘Hello World’ of Hadoop, but when I prepared a small presentation for my team, I realized it was not clear enough to explain Map/Reduce in 5 minutes.

As you may already know, the Map/Reduce pattern is a pattern that is very good for embarrassingly parallel algorithms.

Creating Rich Interactive Web Apps With KnockoutJS – Part 1

With the advent of online games, social apps, Flash/AIR apps, and rich instant-feedback sites
like Google Search and GMail, consumers are demanding more and more interactivity.

While interacting with your app customer now expect:

  • Browser-side processing (calculation, business rules, …)
  • Instant validation
  • Instant visual feedback: animation/effect while making changes (add/remove/update)
  • Dynamic clues on what to do next
  • More same / on page functionality (without the need to refresh or navigate to other pages)

For a while adding a sprinkling of AJAX and localized visual refresh using jQuery UI was sufficient.

Zanata is an open source translation platform written in Java that offers translation memory, an online translation editor, and workflow integration with REST APIs and command-line tools. For translators, it is a web browser-based translation environment where previous translations provide context for their work. For software developers, it’s an integration tool that provides a centralized localization repository along with translation tools that save time and resources.

Product Manager, Runa Bhattacharjee and Lead Developer, Sean Flanigan, have more to say in this interview.

Why is Zanata needed and who is it for?

Runa Bhattacharjee (RB): The primary motivation for this project was to set up a tool that would provide a uniform translation platform with rich features and takes out the hassles of having to learn a million tools to work with. Translation, especially technical translation, can be extremely tricky because of the new kind of content and technology involved and may sometimes require a lot of research by the translators. In these situations, translators often do not like to have to work with tools that take their concentration away from the core part of their work. Translation tools like Zanata provide that abstraction…Read more at OpenSource.com

Index 2: F Grade és ami utána van 

Whereas most designers start with mock-ups, Sharp developed and coded 50 working versions of the site, experimenting with various column widths, layouts, and ways of presenting the pictures. “From the beginning, we were aware that if we were going to get somebody to spend all this time putting together a collection, at the very least, the collection had to be beautiful,” Silbermann says. As Sharp puts it, “The grid was everything.” His final version displayed interlocking images of a fixed width–192 pixels–and varying heights. When new images were pinned, the entire site would rearrange itself, meaning that users rarely saw the exact same home page twice. ( Can Ben Silbermann Turn Pinterest Into The World’s Greatest Shopfront?)

Hétfőn hajnalban az első benyomásaimat írtam le az indexes változásokról. Most egy kicsit részletezőbben, egyszersmind unalmasabban szeretném összefoglalni egy nap használata után még egy körben az észrevételeimet. 

Mindenekelőtt a hétfő reggeli állapothoz képest (8 megabájtos nyitóoldal) valamelyes javult a helyzet. Sikerült optimalizálni a nyitóoldalon 2 megabájtot. Ez még így is négyszer-hatszor olyan nehéz oldal, mint egy átlag médiaszájté. Mert ugye az Index eredeti, valamint az “Index 2” oldala egyszerre töltődik be, ami azt idézi elő, hogy eszement mennyiségű kép, javascript töltődik le, és ráadásul nem is mindig a legoptimálisabban.
