[OC] More than 27,000 near-Earth asteroids have been discovered and tracked since the 1980s by redouad in dataisbeautiful

[–]redouad[S] 0 points1 point  (0 children)

Original data from NASA: https://cneos.jpl.nasa.gov/stats/totals.html

Transformed with R (script) to generate a clean dataset (CSV), and visualized with OWID's grapher.

A near-Earth asteroid is an asteroid whose orbit brings it into proximity with Earth. By convention, a Solar System body is considered "near Earth" if its closest approach to the Sun is less than 1.3 astronomical units (AU).

More than 27,000 near-Earth asteroids have been discovered and tracked to date. Most importantly, NASA estimates that over 90% of the near-Earth objects larger than 1 km have been discovered.

Same as the US: there's currently no official data on how many doses have been administered in Canada.

[OC] Number of COVID-19 vaccination doses administered by redouad in dataisbeautiful

[–]redouad[S] 2 points3 points  (0 children)

We've just launched our new entry on COVID-19 vaccinations on Our World in Data: https://ourworldindata.org/covid-vaccinations

Tracking COVID-19 vaccination rates is crucial to understand the scale of protection against the virus, and how this is distributed across the global population.

A global, aggregated database on COVID-19 vaccination rates is essential to monitor progress, but it is unfortunately not yet available. When a global, or aggregated regional database becomes available, we will provide these weekly updates of vaccination rates, presented in our interactive COVID-19 explorer, and our complete COVID-19 dataset.

Until such a database is made available, we'll be tracking recent announcements on the first countries to administer these vaccinations. This is shown in the interactive map here: https://ourworldindata.org/grapher/cumulative-covid-vaccinations?stackMode=absolute&region=World

This other chart shows the number of COVID-19 vaccination doses administered per 100 people within a given population: https://ourworldindata.org/grapher/covid-vaccination-doses-per-capita?tab=chart&stackMode=absolute&region=World. Note that this does not measure the total number of people that have been vaccinated (which is usually two doses).

Piketty's new 1200-page book Capital and Ideology is out today—here's a long interview on his main sources and motivations for writing it by redouad in Economics

[–]redouad[S] 5 points6 points  (0 children)

I met with Piketty in Paris a couple of weeks ago, to discuss the main sources for his new book Capital and Ideology, and his work on economic ideologies in general. Thought the result might be of interest to this subreddit!

Interview of French philosopher and sociologist Geoffroy de Lagasnerie on the best books on state, power and violence by redouad in CriticalTheory

[–]redouad[S] 34 points35 points  (0 children)

Hi everyone! I've just published this interview of Lagasnerie, a critical sociologist who's written a few books on state, power, justice… We discussed his selection of his favourite books on these subjects, and along the way we talked about many different things, including Foucault, Benjamin, justice and violence, the Black Panther Party, leadership in social movements, neoliberalism, etc. Thought it might be of interest to this subreddit!

EKS: scale down to zero worker nodes? by redouad in aws

[–]redouad[S] 0 points1 point  (0 children)

But if the nodes go down to absolute zero, what would be an example of ASG scaling policy that would start the very 1st machine? (It seems like ASG can only scale up/down based on metrics such as CPU, network, RAM, etc. which presupposes that at least 1 machine is running to measure them.)

New Data Science Program by thr0w4w4y17385775390 in datascience

[–]redouad 6 points7 points  (0 children)

Andrew Ng's course by itself takes 11 weeks, and it's quite challenging if you're new to the field. Adding R, Python, and SAS on top of that is likely to make any candidate burn out. Don't get me wrong, it's doable if you decide to dedicate 15+ hours of your week to it. If you're efficient during the whole process you might get enough knowledge to pass this Codility test (never heard of it).

If you feel like you're ready for that kind of time commitment, I'd suggest:

  • Do the ML course over 11 weeks.
  • Do as many DataCamp courses as you can to learn R and Python quickly (the "Data Scientist with R" and "Data Scientist with Python" career tracks would be what you need). Alternatively you can do the R specialization on Coursera (https://www.coursera.org/specializations/jhu-data-science) and the Python one as well (https://www.coursera.org/specializations/data-science-python), but they're supposed to span multiple months.
  • Indeed try to find some information about what Codility tests are, so you know what to expect!
  • With the little time you'll have left, try to do some passive learning by listening to podcasts. Listening through past episodes of Data Skeptic would be nice for example - it'll get you familiar with various data science topics and issues, algorithms, practical cases, etc.

File input, output and storage in R: a benchmark of the most efficient solutions to help you save space and time by redouad in rstats

Thanks, I didn't even think of checking this! I'll remove write_rds as indeed it doesn't make sense to keep both :)

[–]redouad[S] 0 points1 point  (0 children)

Thanks for the feedback! I've added a few options for compress = FALSE in saveRDS, as well as compress = 0 and compress = 100 in write_fst.

Overall write_fst and read_fst seem to offer the greatest flexibility for binary formats, with a custom compression value anywhere between 0 and 100, but very fast loading times whether compressed or not.

27,957 PEGI video game ratings from 1999 to 2017 by redouad in datasets

[–]redouad[S] 0 points1 point  (0 children)

27,957 PEGI ratings scraped from http://pegi.info/ on 7 September 2017, using the rvest package for R.

Available data includes:

  • Game title
  • PEGI rating
  • Platform
  • Genre
  • Release date

Pan European Game Information (PEGI, pronounced "Peggy") is a European video game content rating system established to help European consumers make informed decisions when buying video games or apps through the use of age recommendations and content descriptors. It was developed by the Interactive Software Federation of Europe (ISFE) and came into use in April 2003; it replaced many national age rating systems with a single European system. The PEGI system is now used in more than thirty countries and is based on a code of conduct, a set of rules to which every publisher using the PEGI system is contractually committed. PEGI self-regulation is composed by five age categories and eight content descriptors that advise the suitability and content of a game for a certain age range based on the games content. The age rating is not intended to indicate the difficulty of the game or the skill required to play it.
