thearn4··on By the end of 2017, Google hopes to prove quantum computers can beat classical
Interesting, I assumed they meant the term colloquially.
thearn4··on By the end of 2017, Google hopes to prove quantum computers can beat classical
It wasn't clear to me either. Demonstrated "supremacy" over conventional general-purpose CPUs, as described in the article, does certainly read like hyperbole.
thearn4··on Ask HN: What podcasts are you listening to?
In no specific order:

My brother my brother and me

Hardcore history

Science friday

Software engineering daily

Data skeptic

Linear digressions

Math mutation

Omega tau

I've listened to a ton more, but I tend to get tired of some and move onto others. I used to love radiolab and this american life, but find them kind of annoying now.

thearn4··on Advantages of Using R Notebooks for Data Analysis Instead of Jupyter Notebooks
Out of curiosity, what was the motivation for switching from Python to R for analysis, was there a particular R package that you were looking to use?
thearn4··on Teaching Pandas and Jupyter to Northwestern journalism students
I'll give this a shot, I like the idea of editing a file within a separate tab of the web interface.

Anything to help refactor things into and from file and the notebook is nice.

thearn4··on Teaching Pandas and Jupyter to Northwestern journalism students
I guess I could see that. Maybe I need to learn more of the keyboard shortcuts and magic methods.
thearn4··on Teaching Pandas and Jupyter to Northwestern journalism students
I really like Jupyter, but somehow I'm not in love with it. Like, every time I fire it up to use it for quick data analysis, I seem to inevitably end up back in sublime + bash, sending plots to disk. Am I the odd one out?
thearn4··on Why printers add secret tracking dots
Firing pins are pretty easy to swap out, though. Easy enough that this could be used to tamper with evidence or even frame someone. It doesn't really seem like a great idea.
thearn4··on The asymmetry in storytelling between math and the other sciences
It does seem strange that you have to typically "pay your dues" with 4-ish semesters of calculus (calc i, ii, ii, diffy-q, and maybe pre-calc) before you take anything else. It's very strange as a gate-keeper to the subject.
thearn4··on Many Colleges Fail to Improve Critical-Thinking Skills
I teach college occasionally, and definitely agree. It is a conveyer belt from freshman to senior, and those students who have not thought beyond their coursework may be in for a rude surprise post-graduation.
thearn4··on A list of practical projects that anyone can solve in any programming language
Thanks for sharing. I'm putting together materials for a course on data structures that I'm teaching this fall.

I have the theory part covered, but I'm always on the lookout for things that could make for decent practical assignment problems - reasonably attainable in scope, but without being too contrived.

thearn4··on GNU Shepherd
I'm not sure what their release process looks like, but the Github for supervisor seems reasonably active: https://github.com/Supervisor/supervisor

Sadly it doesn't seem to play well when run under Python 3. Not a big deal now, but hopefully one of these years, desktop Linux distributions will have a 3.x release of Python as the default.

thearn4··on GNU Shepherd
How does something become an official project under the umbrella of GNU, other than adopting a GPL? I'm guessing the FSF somehow curates and leads the individual efforts, before it can be called "GNU $THING"?
thearn4··on Too many people are buying cars using financial products they do not understand
Yep, my 2012 Civic was bought on 1% financing. Paid off now, still runs great, and I kept the would-be total payment in cash in retirement accounts.

Probably could have done better on a used car, but for once I wanted to be the one to run something into the ground. Still waiting on that.

thearn4··on Oh My Gosh, It’s Covered in Rule 30s
I agree, it does get old fairly quickly. I also don't think cellular automata has made the giant "new kind of science" impact that he proposed that it would.
thearn4··on Ask HN: Best current book to learn JavaScript?
Getting your hands dirty is definitely a good thing, but CodeAcademy is a bit dry. The best thing I've found is trying to get someone to make something that THEY want or need. For someone 100% new to programming, that can be a bit tough though. So books, classrooms and MOOCs do have their place I think.
thearn4··on Ohio Sues 5 Major Drug Companies For 'Fueling Opioid Epidemic'
It does seem like the AMA at least should answer for something.
thearn4··on Ohio Sues 5 Major Drug Companies For 'Fueling Opioid Epidemic'
It's an issue here on the outskirts of Cleveland as well. I wouldn't call it a blight per se, but I'm not sure why Ohio in particular is suffering this in greater amounts than other areas.
thearn4··on Paul Buchheit on Lessons Learned from Investing in 200 Startups
I remember discussions about how it seemed congruent to the "do no evil" unofficial motto.
thearn4··on Catching Up with Intel's Python and AI Work at PyCon [audio]
Sounds interesting, I'll have to give it a shot then!
thearn4··on Catching Up with Intel's Python and AI Work at PyCon [audio]
Is this an alternative to the cpython interpreter, or is it just a bundle with numpy-backed MKL? Not that it wouldn't be handy, but anaconda python does provide this too.
thearn4··on LibreOffice leverages Google’s OSS-Fuzz to improve quality of office suite
git + markdown could be an interesting combo for back and forth written revisions (we do it at work with latex and git for research papers). But to someone outside of the tech community, it looks 100% alien of a workflow.
thearn4··on First Science Results from NASA’s Juno Mission
The congressional politics of the districts where the development of human space flight systems are a major employer are, unfortunately, a huge factor in NASA's budget earmarks.

Also known as the "Alabama Space Mafia".

thearn4··on Why American Workers Now Dress So Casually
Where I'm at (NASA), there is a broad spectrum of dress formality. Generally I do the typical polo shirt and khaki or jeans. When giving a local presentation or low-level sight visit, business casual. When going to a conference or getting a visit from HQ/congress/president's staff, business suit.

I notice more academics having the same approach as well. I dress to match expectations, but generally I'm past the point where visually impressing someone would impact my upward mobility.

thearn4··on Why American Workers Now Dress So Casually
> Companies under French management

I'm curious about this one, how come?

thearn4··on Topics in Core Mathematics at Graterford Prison
That's a great read, thanks for linking it.
thearn4··on How army rations helped change food
I didn't trade, but Italian army rations looked pretty good.

U.S. MREs are obviously awful when compared to pretty much any prepared food, but when you're genuinely hungry you mind that a lot less.

thearn4··on Get Started with Kotlin on Android
Anything in particular stick out as bad in the API?

I haven't tinkered with mobile development in awhile, but I remember content providers feeling like an oddly thought-out concept at the time.

thearn4··on The Heroin Business Is Booming in America
I hadn't noticed that pattern, but it is an interesting one.
thearn4··on Whose Parents Pay for College?
I'm in that 45%, though I used military benefits to cover it. So really, American taxpayers as a whole paid for my bachelor degree.
