  Programming Languages for Machine Learning Implementations

Machine learning algorithms have a much better chance of being widely adopted if they are implemented in some easy-to-use code. There are several important concerns associated with machine learning which stress programming languages on the ease-of-use vs. speed frontier.Speed The rate at which data sources are growing seems to be outstripping the rate at which computational power is growing, so it is important that we be able to eak out every bit of computational power. Garbage collected la...

  Redesigning the Technical Hiring Process

Since my last post on technical interviews, I’ve been fairly involved in hiring at Pulse as we grew our team from 6 people when I joined last November to 14 full-timers. In my previous post, I suggested that technical interviews, in the conventional sense, are not especially effective (by technical interviews, I mean the traditional 45 minute coding-at-a-whiteboard and algorithm puzzlers interviews). Those do a great job of telling you how well a candidate is at acing those types o...

  SOME LESSONS LEARNED

Note: Google was kind enough to invite me to give a short talk at their Zeitgeist conference earlier this week. It was a really interesting conference and I got a chance to meet a lot of people I admire. For my talk, I decided to use material from some of my blog posts over the years that I thought might appeal to a broader audience. Unfortunately, I was still recovering from a nastly cold/flu so I didn’t deliver the talk as well as I’d like.  Below is the text.Today, I wanted...

  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 ...

  Why isn't all internet traffic encrypted?

The biggest problem is that you must be able to verify that you're encrypting to the correct key. Without it, encryption would be practically useless, as anyone could perform a man-in-the-middle attack on the connection and remain undetected.In typical SSL/TLS, as well as other protocols using X.509, this verification is performed by "certification authorities", which are explicitly marked as "trusted" by web browsers and operating systems. Unfortunately, these CAs usual...

  Big file transfer in Linux

It's very common that we need to transfer files between two different hosts such as backups. It is also an very simple task, we can use scp or rsync to complete the task well. But what if the file is very big, it may take some time to transfer it. How can we transfer a big file with high speed? Here we propose one solution. Copy file If we copy one uncompressed file, then we should follow below steps: Compress data Send it to another host Uncompress the data Verify the data integrity This will...

  A Different Kind of Technical Interview

Everyone who's been programming professionally for a while knows the standard format of the technical interview. You go in, there's a whiteboard in the room, and you write code on it to answer questions.Everyone also has the same basic complaints about these interviews. In a normal work environment, you have access to an API or search engine, but at a whiteboard you don't. Whiteboard questions generally don't include much in the way of overall design, and they're typically limited to simple algo...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...

  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...

  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...
