  In praise of impractical programming

Although it’s become a cultural mainstay now, I still remember when I first saw that thick book — the one with the wizard on the cover — about a school for magic where wonders are easily conjured by those who know the proper spells. Of course, I’m talking about the Structure and Interpretation of Computer Programs. There was that other book with the spells, but the “Wizard Book” sincerely claimed to teach magic. For the past few years, I’ve been ...

  What programming languages should I learn?

Since I started this blog, I have gotten quite a few emails asking me “What programming languages do you recommend for X?” I often finding myself writing something along the lines ofI would honestly recommend python. Something about me being biased because I know and love it.  Usually say something about the competing technology with a back handed insult. Also if they are starting out I would recommend a language that enforces better OO (Object Orientated) practic...

  12 Things A Programmer Really Needs To Know

How do you answer the question, “what do I need to learn to be a good programmer?” I have written posts trying to answer that question, typically focusing on the languages that you should learn or the algorithms and other techniques you need to know. What about the rest of a programmer’s life? This is a less serious look at the life of a programmer. So, what does a programmer really need to know?Caffeine â€“ You need to find your preferred caffeine delivery system. M...

  How To Make The Most of Your Least Productive Time

Everybody talks about mastering the art of staying productive. Not many people willingly accept that such efforts are futile. It’s impossible to stay productive 100% of the time, and this will never change. Something that I believe to be just as important, if not more so, is what we make of our least productive time. We all have the capacity to be extremely productive for some part of the day. Even the world’s grandest underachievers. But I believe that to be successful runni...

  Tips of Drafting an R Markdown Document

When presenting the data summary and exploratory analysis, we used to copy a lot of tables, charts from Rstudio to PowerPoint, which makes the presentation preparation painful. It becomes essential for data scientists to make use of better reporting tools, such as R markdown, Jupyter notebook to prepare the analysis presentation in a more efficient and organized way. Of course, we want this to be reproducible! In this post, I would like to share some tips of using the right tools to draw tables,...

  Our Go Cache Library Choices

In Build a Go KV Cache from Scratch in 20 minutes, I walked you through what matters when writing a local cache, and eventually implemented one, whose performance was beaten badly by that of the popular go-cache on Github though. However, the bright side is that we can learn a lot from those excellent Github Go cache products, studying their features, applicable scenarios, and implementations, and extracting what we need. In this article, I will mainly analyze and compare the four...

  What's Wrong with the For Loop

Closures in Java are a hot topic of late. A few really smart people are drafting a proposal to add closures to a future version of the language. However, the proposed syntax and the linguistic addition are getting a lot of push back from many Java programmers. Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to...

  The Wasteful Legacy of Programming as Language

A few years ago I visited a friend who is a graduate student in linguistics. After some time he asked me if I was aware of the work by Chomsky on formal languages. I told him that yes, Chomsky work was a basis for much of the developments in theoretical computer science. More than that, I was glad to learn that there was something technical that I could share and discuss with other people in linguistics. At the time I found this was just a great coincidence. It was only recently, though, t...

  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.  ...

  What makes a great IT project manager

Since IT project management is a field in constant flux, there's no one universal definition of a great IT project manager. Still, there are some skills and features that can be easily adapted to any working environment, meeting new organizational needs and consequent challenges. A significant problem is the fact that project manager will mean different things to different people (even within the same organization!). Some say that the greatest IT project managers are those who are able to balanc...
