electricityMap
A real-time visualisation of the CO2 emissions of electricity
...It should provide a breakdown by generation type. Often fossil fuel generation (coal/gas/oil) is combined under a single heading like 'thermal' or 'conventional', this is not a problem. Citizens should not be responsible for the emissions associated with all the products they export, but only for what they consume. Consumption-based accounting (CBA) is a very important aspect of climate policy and allows assigning responsibility to consumers instead of producers. Furthermore, this method is robust to governments relocating dirty production to neighboring countries in order to green their image while still importing from it. -

data-diff
Efficiently diff rows across two different databases
...Until now, there has not been any tooling to ensure that when the data is correctly copied. Replicating data at scale, across hundreds of tables, with low latency and at a reasonable infrastructure cost is a hard problem, and most data teams we’ve talked to, have faced data quality issues in their replication processes. The hard truth is that the quality of the replication is the quality of the data. Since copying entire datasets in batch is often infeasible at the modern data scale, businesses rely on the Change Data Capture (CDC) approach of replicating data using a continuous stream of updates. -

OmicSelector
Feature selection and deep learning modeling for omic biomarker study
OmicSelector is an environment, Docker-based web application, and R package for biomarker signature selection (feature selection) from high-throughput experiments and others. It was initially developed for miRNA-seq (small RNA, smRNA-seq; hence the name was miRNAselector), RNA-seq and qPCR, but can be applied for every problem where numeric features should be selected to counteract overfitting of the models. Using our tool, you can choose features, like miRNAs, with the most significant diagnostic potential (based on the results of miRNA-seq, for validation in qPCR experiments). -

FuzzyWuzzy
Fuzzy string matching in Python
We’ve made it our mission to pull in event tickets from every corner of the internet, showing you them all on the same screen so you can compare them and get to your game/concert/show as quickly as possible. Of course, a big problem with most corners of the internet is labeling. One of our most consistently frustrating issues is trying to figure out whether two ticket listings are for the same real-life event (that is, without enlisting the help of our army of interns). To pick an example completely at random, Cirque du Soleil has a show running in New York called “Zarkana”. ... -

"Circular Multilateral Barter" (CMB) is aimed at supplying entrepreneurs with a way to exchange goods and services within a p2p-network, without using money, overcoming the "double coincidence of wants" problem, inherent to traditional barter. Most importantly, CMB allows traders to issue their own currencies (called "products"), which others can redeem, trade, or make payments with. One thing that distinguishes CMB from other "credit commons" is that all debts in CMB are user-to-user debts. There is no central administrative authority to decide who deserves to be trusted and who does not. ...

RumbleDown
Unifying communication flows to one point
...Don not forget: in the future some sort of encryption will be called upon to protect user data and privacy. At that time we will have to address the necessary controls issues. For the start up that will not be a problem. The sooner we get to having to cross that bridge, the better.
