  What is Hystrix and How does Hystrix work

Background In distributed systems, there is one effect where the unavailability of one service or some services will lead to the service unavailability of the whole system, this is called service avalanche effect. A common way to prevent service avalanche is do manual service fallback, in fact Hystrix also provides another option beside this. Definition of Service Avalanche Effect Service avalanche effect is a kind of effect where the service provider fails to provide service which causes t...

  India: The World's Secret Silicon Valley

You might not know it, but a key cog in the global innovation machine is hiding in plain sight in the world's largest democracyReutersFor many firms, developing new products for consumers around the world is the most visible manifestation of innovation - the "real deal." But many people still see India as a place where other people's ideas are made or executed and not where innovation begins. (After all, you don't hear about an Indian equivalent to Google, iPod or Viagra.) Bu they're wrong. In m...

  Functional Programming Is Hard, That's Why It's Good

Odds are, you don’t use a functional programming language every day. You probably aren’t getting paid to write code in Scala, Haskell, Erlang, F#, or a Lisp Dialect. The vast majority of people in the industry use OO languages like Python, Ruby, Java or C#–and they’re happy with them. Sure, they might occasionally use a “functional feature” like “blocks” now and then, but they aren’t writing functional code.And yet, for years we’v...

  Why developer-friendliness is central to API design

Today, APIs play a bigger role in software development than ever before. The evolution of computing has been dominated by ever-increasing levels of abstraction; the use of higher-level languages, of course, but also the development of platforms, libraries, and frameworks. Professor Douglass C. Smith claims the progression of this second category far outpaced the development of programming languages.  Developers are also noticing that difficulty has shifted from designing algorithms a...

  10 Points about Java heap memory

When I started java programming I didn't know what is java heap or what is heap space in Java, I was even not aware of where does object in Java gets created, it’s when I started doing professional programming I came across error java.lang.outofmemoryerror then I realized What is Heap in Java or Java Heap Space. Its happens with most of programmer because learning language is easy but learning basics is difficult since there is no formal process which can teach you every basics of pro...

  Valid JavaScript variable names

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them. Reserved words The ECMAScript 5.1 spec says: An Identifier is an IdentifierName that is not a ReservedWord. The spec describes four groups of reserved words: keywords, future reserved words, null literals and boolean lite...

  How Integers Should Work (In Systems Programming Languages)

My last post outlined some of the possibilities for integer semantics in programming languages, and asked which option was correct. This post contains my answers. Just to be clear: I want practical solutions, but I’m not very interested by historical issues or backwards compatibility with any existing language, and particularly not with C and C++. We’ll start with: Premise 1: Operations on default integer types return the mathematically correct result or else trap. This is th...

  If PHP Were British

When Rasmus Lerdorf first put PHP together, he - quite sensibly, despite his heritage - chose not to write it in Greenlandic or Danish. Good job too - that would have been rather unpleasant to work with. He opted instead, being in Canada at the time, for the local tongue. No, not French - that bastard dialect of the Queen's English commonly referred to as "US English"1. PHP developers in Britain have been grumpy about this ever since. What was he thinking? And more importantly, how do we ...
