I'm by no means an expert at machine learning, but, given how organized the scikit learn libraries are, building a simple classifier as show in the example would be a few days of work at the max. In fact, an initial first version can b

1. People don't store such large amounts of data in a conventional database (especially relational DB). Depending on the exact requirements, the popular choices are HBase, Cassadra or even flat files in HDFS. 2. To analyze the data, Ha

Maybe this is the norm in big enterprises, but I have not actually come across any company which hosts a local package repository for commonly available packages.

Well done I guess :) I worked briefly at ThoughtWorks, but definitely don't have any vested interests. ThoughtWorks produces not-so-great products too (like Mingle), but Go CI is definitely a great piece of software. And, I say that as

I have worked with many open and proprietary CI tools, and find GoCD to be the best in this space right now. It supports both Continuous Integration and Continuous Delivery. They also made it open source last year: https://www.go

On the other hand, as your system gets more complex, you will start missing tried and test libraries from some of the more mature languages you have mentioned. Maybe the extra time you have to spend writing that code will compensate for the

You can't reverse the trend if you don't know why exactly it's happening. First talk to those who are cancelling to find out why. For e.g. add a mandatory field on the cancellation form that asks them to describe why they are

Here's another way to look at it: Facebook, Google & Twitter sell their software to advertisers that allows them to reach their target audience. Here "selling" is actually a service. Uber is mostly a software company - th

1) Once the training is done, the prediction part is simply matrix multiplications - I would think that's probably faster and far easier to parallelize than any other advance feature extraction algorithm you will be performing real tim

What task are you learning the features for? If it's classification, instead of treating it as a two step (feature generation followed by classification) problem, I suggest that you just use a multi-layer neural network with a sigmoid

Practically speaking, someone looking for a job change does not have 10 hours to spend on every company's coding challenge. So, you will have only a few people who would go out-of-the-way to do something like that. And, that's not

This has been an area of interest for me as well. I have spoken to a lot of engineers and hiring managers on this subject, and my takeaway is that no two engineers seem to agree on what's the best way to hire people. Some think that co

This also explains why VCs look to fund billion dollar opportunities even if they look a little risky. VCs are in the game for big exits and that's how the math works out. Something to keep in mind when you're planning to raise mo

Being on AWS does not necessarily mean that you don't need a devops person - especially at the scale where not being on AWS actually makes a difference to your margins. I have seen quite a few people move off AWS successfully onto bare

What would your ideal interview process be like? I often hear about horrible interview processes on HN, but it would be interesting to hear how it can be improved.

For a very long time, I did not want to use ad blockers. I have used ads in the past to monetize some of my own projects, and I really did not want to stab the creators of quality content. However, last week I finally reversed my decision a

I want to give you an alternate perspective. Sometimes it's far more liberating to accept and move on. There is this book called "Dip" by Seth Godin. I recommend that you read it (it's just 70 odd pages). In that book, S

I'm saddened to read such dismissive comments on HN. I think it takes someone to have been in a similar position to understand the plight of the OP. The CEO had a chance to fix this and do the right thing, but firing her was the easy t
