  A plugin to update last_error in Delayed Job

delayed_job is a process based asynchronous task processing gem which can be ran at background. It will fork the specified number of processes to execute the tasks asynchronously. The task status is usually stored in the database so that it can be easily integrated into a Rails application where asynchronous job execution is desired. Normally when a job fails to execute or error occurs, it would save the error into the database with the column last_error. Ideally all these will be handled b...

  Small team? Fix your life with a non-virtual assistant

Like many others, I tried “outsourcing my life” using a digital assistant. A year and a thousand bucks later, I’ve received one department store recommendation and an admittedly adequate spreadsheet of competitive research.I have since cancelled. Why didn’t it work for me?I think I just didn’t trust it/them/him/her (that I even have this ambiguity is indicative of the issues).Most of my mindless time-sinks involve at least a credit card number and are often a con...

  Obviously Correct

What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

  A Solution to CPU-intensive Tasks in IO Loops

Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer.  A provocative title to a provocative article.  The only thing it didn’t really provoke in the commentary was much thought ;)  Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or  thread per request; same difference) model as superior.  Yet we all remember where the blocking-IO forking model got Apache in the early days.  ...

  How to Seem (and Be) Deep

I recently attended a discussion group whose topic, at that session, was Death.  It brought out deep emotions.  I think that of all the Silicon Valley lunches I've ever attended, this one was the most honest; people talked about the death of family, the death of friends, what they thought about their own deaths.  People really listened to each other.  I wish I knew how to reproduce those conditions reliably.I was the only transhumanist present, and I was extremely careful not...

  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...

In general The following are the basic operations that almost every Kubernetes user takes. Check ðŸ‘...

  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...
