Beware these engineering mistakes for your early stage software startupIn 2016, I gave technical advice to a first-time entrepreneur building a seed-funded food delivery marketplace. In my view, every tech choice the company had made was wrong.The CEO believed in “empowering the engineer.” They then let their first engineer choose the framework (Scala/Play) because it was what the engineer wanted to use, not because it made sense for the company, their use case, or the recruiting pool. Much of the early technical work had been outsourced. Their product roadmap was widely optimistic (web and mobile concurrently) despite the fact that most of the business was still unvalidated. It was a recipe for disaster.Startup engineering is different from any other type of software engineering. It (...)

I want to go fastI haven’t been #programming for long, but I’ve gotten to the point where I’m a little bored working in Ruby, Python, Scala, PHP, C#, and JavaScript (to name a few). New languages feel like old languages, remixed. The concerns are more or less similar and the challenges feel the same. I need a new challenge.(source: memeshappen.com)But what does that mean? For me that has meant learning C++ and, well, building things that go really fast. This means learning a new domain and taking #software craftsmanship to a new level. Keep reading and I’ll explain.Wanting To Go Fast (in C++)The ability to go fast has always been there in the form of C or C++. But I had always heard ugly rumors, seen ugly code, and had the general notion that it was really easy to shoot yourself in the (...)

Previously, we have discussed some of the advantages and features accompanying MapR-DB. However, this time we are going to get our hand dirty while using this enterprise-grade database.When using MapR-DB, it is a common practice to serialize and deserialize our business objects (commonly known as POJO) from/to JSON all the time since MapR-DB data is stored using JSON format. These operations are very common and frequent so we will take a look at them from Scala’s point of view.MapR-DB Document APIThere are a series of steps to be followed to create new objects and to insert them into MapR-DB. Let’s look at the typical workflow.▻https://medium.com/media/e33ad01ea3ab9948ecff3c2b4e26e11b/hrefThis is the basic steps to insert into MapR-DB.

We are #java shop, and we use #lightbend Lagom Framework. Based on this context, I asked today:Am I not still be able to create a new service in Scala?Roberto (@RobbieTweetsJr) gets back to me:You can do whatever you want. Whether it gets approved is out of my hands. :joy:…. Roberto is typing for long long time so I close Slack until I get notified….It has nothing to do with complicated or easy. No one’s going to argue that it’s not simpler to do it in #scala, but in a project this size, it’s not that simple. It’s easy for you because you’ve got the knowledge. But there are at least 40 other Java developers on this project, not all of which have Scala experience. This is not your traditional software development company.I said:Let’s teach them.Roberto, very polite says back:Now you’re asking a (...)

“How to take over the computer of any Java (or Clojure or Scala) developer

Unless you take very careful steps that involve paying someone $10, JARs you download can be man-in-the-middled, and code you execute on your system can be replaced by malware.

When can this happen? If you ever use a public wifi network in a coffee shop, or are on a wifi network that someone took over you can be man-in-the-middled. Your ISP can man-in-the-middle you at will, and some do so in order to serve you ads. Or, perhaps you are subject to a man-in-the-middle attack from a state actor.”

Slender Means

So what’s below is a somewhat tongue-in-cheek list of suggestions for facilitating productive and interesting discussions comparing languages. Many of them are not specific to our little R/Python/Matlab/Julia skirmishes, but apply to lots of different language wars (C++ vs. Java, Python vs. Perl, Ruby vs. Python, Clojure vs. Scala, Haskell vs., I dunno, everybody?) The last section is comprised of a couple of very general notes about civility. I’m strongly in favor everyone’s right to be a smug prick on the Internet. But, you know, you should probably try not to be a smug prick on the Internet.
