HPR2958: Haskell modules
December 04, 2019 00:00 - 11.6 MBWith small programs it’s easy enough to have all code in single file. But as the program grows, you eventually want to organize things into separate files. In this episode I’ll talk a bit how to define modules and how to use them. Defining Each module is defined in separate file. In our example, we have file called multiplexer.hs, which contains our module definition. At the beginning of the file, we have following: module Multiplexer (mix, match, Plexer, Scooper(..)) where .... We’...

HPR2955: Machine Learning / Data Analysis Basics
November 29, 2019 00:00 - 10.2 MBIn this episode, I talk about different techniques that we can use to predict the outcome of some question depending on input features. The different techniques I will go through are the ZeroR and OneR that will create a baseline for the rest of the methods. Next up, we have the Naive Bayes classifier that is simple but powerful for some applications. Nearest neighbor and Decision trees are next up that requires more training but is very efficient when you infer results. Multi-layer perc...

November 22, 2019 00:00 - 7.58 MBWe previously looked at the NIST Security Framework, which lays out how organizations should manage their network security. That may have seemed a bit dry, so let’s look at this case study to put some flesh on those dry bones. Failing to manage your security risks properly can have significant consequences.

HPR2949: Grin and Beam: The 2 major mimblewimble blockchains
November 21, 2019 00:00 - 11.7 MBLast time we reviewed the mimblewimble protocol for blockchain networks. This is an innovative protocol focused on privacy and scalability. In this episode we take a closer look at the two major implementations of mimblewimble, called Grin and Beam. They are both interesting projects that take very different approaches, yet both have managed to launch working blockchains that preserve the core strengths of the protocol.
HPR2948: Testing with Haskell
November 20, 2019 00:00 - 20.5 MBIntro I have liked writing automated tests for a long time, so it’s not a surprise that I end up writing them in Haskell too. This is very broad topic, so this episode only scratches the surface. HSpec HSpec is testing framework that automatically detects tests, like most of the modern systems. It supports hierarchies, so one can organize tests by feature for example. spec :: Spec spec = do describe "Very important feature" $ do it "Execution should be error free" $ do ...
HPR2947: The Mimblewimble Protocol
November 19, 2019 00:00 - 10.7 MBFinancial privacy is critical for adoption of cryptocurrency as a means of exchange. Individuals worry about employers monitoring their spending details, insurers increasing rates based on purchases and landlords raising rents when they get a promotion.

At the same time, they need to selectively disclose financial data to governments and mig...

HPR2940: Better Social Media 05 - Mastodon
November 08, 2019 00:00 - 6.91 MBAs mentioned earlier, Diaspora was one of the earliest alternative, privacy-respecting social media platforms, but it was focused on being an alternative to Facebook (and it has done this fairly well). But that leaves the other big platform of the social world, Twitter. Mastodon is a nice federated alternative to Twitter and a nicer place to be. https://www.zwilnik.com/?page_id=1034 Links: https://joinmastodon.org/ https://en.wikipedia.org/wiki/Identi.ca http://pump.io/ https://en.wikip...

HPR2938: Naming pets in space game
November 06, 2019 00:00 - 10.4 MBIntro In the two previous episodes we built a weighted list and used that to build markov chains. This time we’re going to use them to generate some names based on examples. I’m skipping over a lot of uninteresting code in this episode, concentrating only the parts that deal with names. Idea Person in game might hear scurrying sounds inside walls of their quarters. Then they have option of getting a cat, taming a rat or letting someone else deal with the problem.

October 25, 2019 00:00 - 7.74 MBI don’t know if Diaspora was the first of the alternatives to come along, but it was certainly the first I was aware of. It got a lot of attention for the college students who first put it together (and remember that Facebook was originally created by a college student, Mark Zuckerberg). The four students, Ilya Zhitomirskiy, Dan Grippi, Max Salzberg, and Raphael Sofaer, were inspired by a speech Eben Moglen gave to the Internet society’s New York Chapter, where he described centralized socia...

It still wouldn't boot even with the repaired filesystem, but I was able to mount the drive and copy her files to a USB drive. Links Blog post Howto: Repair/Fix MAC HFS+ Partition Using ...

October 23, 2019 00:00 - 14.7 MBIntro Last time we built a weighted list, this time we’re using that to build markov chains. Wikipedia states that “A Markov chain is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event.” and that they’re named after the Russian mathematician Andrey Markov. Configuration We’re after generic system, hence parametrized data types. First part is Configuration a that lists possible startin...
