Book Review: CoffeeScript: Accelerated JavaScript Development Screenshot-sm 100

Michael J. Ross writes "For decades, programmers have written computer code in one language, and then programmatically translated that code into another, lower-level form (typically machine code that can be run directly by a microprocessor, or some sort of bytecode that can be interpreted by a virtual machine). For instance, source code written in C or C++ is compiled and assembled into machine code. In web programming, there are emerging languages and other tools for translating code into JavaScript. For instance, Google Web Toolkit allows the programmer to create web apps in Java. The latest addition to this category is CoffeeScript, a language that can be compiled into JavaScript, and is intended to reduce source code size and clutter by incorporating some of the best operators from other Web scripting languages, particularly Ruby. It is also the topic of a new tutorial, CoffeeScript: Accelerated JavaScript Development." Read on to learn what Michael thinks of this book.

Which is why, when you do use tantalums, you use ones that are specced at twice the voltage you expect over them.

We've used tantalums in some telecom equipment we make, and except for about 5 spectacular failures (explosions, fireballs) on some early prototypes (because of wrong part numbers and such), we've never seen a failure in almost 7 years.

We could not have used electrolytic caps as they would not have survived as long.

BTW: reverse voltage an electrolyte, and witness the explosion (and foul smell) also.... Used to do that to scare people in electronics class.....
Of course, if we redesigned now, I'd probably change out some of the tantalums with ceramic caps.

My family has diesels in Norway (German Fords, 1.8L TDI). Latitude approximately Anchorage AK.
The cars have a secondary heat turbine that is used as a engine heater to get the engine to starting temperature in the morning, and to INCREASE the coolant temperature if it is too low.

The cool thing is that this turbine has its own timer so you basically have a mobile block heater with you at all times...

We have a product with about 15 fairly expensive BGA's on it.
Before RoHS, we had little to no problems with the board. After we switched, we have a lot of problems with cracked solder joints/BGA balls under the BGA's, and they usually doesn't show up right away, but waits for a few thermal cycles.

The ironic thing is htat since we're making telecom equipment, we're excempt from using unleaded solder, but we cannot get the BGA's with anything except unleaded balls.

Netflix Extends "Watch Instantly" To Mac Users 205

CNet is reporting that Netflix has opened up its "Watch Instantly" feature to Mac users (here is Netflix's blog entry). They accomplished this by using Microsoft's Silverlight technology on both platforms, abandoning the Windows Media Player solution that had been employed in the first, Windows-only, version. Silverlight's DRM capabilities meet Netflix's needs, apparently. Netflix warns that this is beta software. Mac users can opt in here, then watch instantly with Safari or Firefox 2+, with the Silverlight plugin in place. Movie selection is somewhat limited.
