Database Application with U of Helinski
This material is intended as a material for Database Application (4 ECTS) of the University of Helsinki practical work course. Course Database Application Prerequisite Courses are Programming Basics (TKT-10002), Advanced Programming Course (TKT-10003), and Database Introduction (TKT-10004).

The course assumes a significant effort in self-study of additional information, and the material is far from covering everything relevant to the course.

Serverless Machine Learning with Tensorflow on GCP
This one-week accelerated on-demand course provides participants a a hands-on introduction to designing and building machine learning models on Google Cloud Platform. Through a combination of presentations, demos, and hand-on labs, participants will learn machine learning (ML) and TensorFlow concepts, and develop hands-on skills in developing, evaluating, and productionizing ML models.

GAN Dissection by CSAIL
The #GANpaint app works by directly activating and deactivating sets of neurons in a deep network trained to generate images. Each button on the left ("door", "brick", etc) corresponds to a set of 20 neurons. The app demonstrates that, by learning to draw, the network also learns about objects such as trees and doors and rooftops. By switching neurons directly, you can observe the structure of the visual world that the network has learned to model. (Try it here.)

Write your own virtual machine
In this tutorial, I will teach you how to write your own virtual machine (VM) that can run assembly language programs, such as my friend's 2048 or my Roguelike. If you know how to program, but would like to gain a deeper understanding of what is going on inside a computer and better understand how programming languages work, then this project is for you. Writing your own VM may sound a little scary, but I promise that you will find it to be surprisingly simple and enlightening.

Bytecode compilers and interpreters
Two fun things happened recently and the proximity of the two made something go click in my head and now I think I understand how bytecode interpreters work.

I went to a class at work called “Interpreters 101” or something of the sort. In it, the presenter walked through creating a dead-simple tree-walking Lisp interpreter. Then he ended by suggesting we go out and re-implement it as a bytecode interpreter or even a JIT.
I joined a new team at work that is working on something Python related. Because of my new job responsibilities, I have had to become rather closely acquainted with CPython 3.6 bytecode.
Since learning by writing seems to be something I do frequently, here is a blog post about writing a small bytecode compiler and interpreter in small pieces. We’ll go through it in the same manner as my lisp interpreter: start with the simplest pices and build up the rest of the stack as we need other components.

Network Protocols: For Anyone Who Knows a Programming Language
The network stack does several seemingly-impossible things. It does reliable transmission over our unreliable networks, usually without any detectable hiccups. It adapts smoothly to network congestion. It provides addressing to billions of active nodes. It routes packets around damaged network infrastructure, reassembling them in the correct order on the other side even if they arrived out of order. It accommodates esoteric analog hardware needs, like balancing the charge on the two ends of an Ethernet cable. This all works so well that users never hear of it, and even most programmers don't know how it works.

On lists, cache, algorithms, and microarchitecture
I’ve been writing a small library of intrusive data structures recently. Singly-linked and doubly-linked lists, being the simplest were also the first ones I implemented. Once I considered the potential for container-specific optimisations by specialising generic algorithms like for_each, transform, and accumulate I’ve realised that there is more to it than just the fact that “lists are slow” and a closer look at them can be quite an educational experience. After all, there’s a lot of code that is not a vectorised loop working with a structure of arrays that fits entirely in the cache and achieves 4 instructions per cycle.

Style-based GANs – Generating and Tuning Realistic Artificial Faces9
Generative Adversarial Networks (GAN) are a relatively new concept in Machine Learning, introduced for the first time in 2014. Their goal is to synthesize artificial samples, such as images, that are indistinguishable from authentic images. A common example of a GAN application is to generate artificial face images by learning from a dataset of celebrity faces. While GAN images became more realistic over time, one of their main challenges is controlling their output, i.e. changing specific features such pose, face shape and hair style in an image of a face.

Computer Graphics in Scratch
TL;DR: This book will not teach you how to use OpenGL or DirectX; instead, it can teach you how OpenGL and DirectX work. In practice you won’t write a software renderer for production use, but understanding how and why a renderer works will let you use OpenGL and DirectX more effectively.

Computer Graphics is a fascinating topic - how do you make Toy Story out of algorithms and some geometric data? Interestingly enough, it’s a mysterious topic not only for the average cinema fan, but also for world-class engineers who just haven’t been exposed to it.

Startup Idea Checklist
I’ve been tinkering with different startup ideas and needed a good checklist to think through them. There are great templates for this already: The YC application, Amazon’s internal press release, and Sequoia’s Writing a Business Plan. I found myself mixing and tweaking these templates because they don’t exactly match my model of the world, so I wrote up my own list.

I use this list both to develop ideas and filter them. If you adopt it, be careful about using it as a filter. Remember that in the early stages, good ideas are very easy to kill.

Think in Math, Write in Code
Programmers love to discuss programming languages. Besides debating their own merits, we integrate them into our identities and even infer things about others who use them. Some even defend a form of Linguistic Determinism that thinking is limited to what is typable.

Since we spend so much time using languages, an interest in making them better is justified. However, the character of these debates suggests that we think of them as something more. Perhaps we have forgotten their primary role. Programming languages are implementation tools, not thinking tools. They are strict formal languages invented to instruct machines in a human-friendly way. In contrast, thoughts are best expressed through a medium which is free and flexible.
