ljcn commented on PDF: Still unfit for human consumption, 20 years later   nngroup.com/articles/pdf-... · Posted by u/ciprian_craciun

If we used html instead of pdf the whole society would collapse.

Didn't anyone notice that it's basically impossible to save an html page today and have it load and render correctly and offline tomorrow?

ljcn · 5 years ago
Not all html pages - what about hackernews? It's mostly tables with minimal CSS (a bit of padding and font*/color), I bet it continues to be perfectly rendered practically indefinitely. At least snapshots on archive.org from 2007 still look perfect.

Was reserving lawns for humans and all of the countryside for bees not already a pretty sweet deal? How are we being out-negotiated by insects?

Wouldn't you rather share a garden with insects? I would.

This maybe a rudimentary question, but if someone was going to study this at a university level, what would they study?

I ask because I'm starting my masters in CS, but I've also been going to workshops/events at a local citizen bio lab and really enjoying it. I'd really like to go deeper into the cross-section of CS and Bio, specifically the kinds of things listed in this repo (modeling biological phenomenon as formal systems, using computation to simulate those systems, etc.)

But when I look at potential programs to pursue after my CS course, I get a bit lost in all the different titles—bioinformatics, systems biology, computational biology, etc. It's hard for an outsider in the field to discern any meaningful delineation. Does anyone with experience in the field know what category of study these resources would fall under, from a university perspective?

> bioinformatics, systems biology, computational biology

Of those bioinformatics is more specific (usually genomics data); the other two are overlapping and pretty non-specific terms.

For example I started a Sys Bio PhD and ended up in a Comp Bio research group. A friend started the same way but ended up in control theory/microbiology.

The title and even the department are somewhat arbitrary and more to do with the organisation at the university than anything else (e.g. I was in CS but my friend was Engineering I think).

If you can find a good interdisciplinary course they will be familiar with people moving around depending on their interests.

Earth’s radius is 6371 km, not ~6 km.

Radius of 6 km is comparable to the size of Halley's comet :-)

(Wasn't able to read the article through the paywall) Does Price is Right use MSRP or what? Because I'll usually just look at my options and choose my lowest one - I have no idea what I should be paying for something.

OnACoffeeBreak · 6 years ago
Something I just realized while reading this article is that the Earth is only about 100 solar diameters from the Sun. This was completely out of proportion with my gut feel.

Edit: change "radii" to "diameters"

ljcn · 6 years ago
About 200 actually (you mistook the diameter for the radius).

*the difference between science and mathematics.

Physicists normally care little whether their mathematical tools are formally proven correct. See: the Feynman path integral. It makes sense and gives correct answers, but as far as I know, it has no rigorous mathematical basis.

ljcn · 6 years ago
Indeed, natural science deals in models, not 'the truth'.

In most cases 'correct' isn't an option, rather a degree of accuracy. If it's consistent with the measurements, or even better if it has predictive power, then it's useful.

If you're using something like "CorrectHorseBatteryStaple6" and consider it a secure password, I have some bad news for you.
ljcn · 6 years ago
It's got 80-120 ish bits of entropy, why is it not secure?

(Assuming you're not referring to it literally being a well known password from a web comic.)

> STOP USING google SEARCH! USE DUCKDUCKGO!

I want to stop using Google, but please realize that DuckDuckGo is only competitive with Google if English is your only language (maybe even only if you're American?). There are loads and loads of people on HN for whom DDG is a poor experience.

In my experience DDG is extremely poor for localized results, especially those in other languages than English. Previously I recommended StartPage.com for my fellow Europeans, but StartPage has been bought by a shady company [1] and should not be used anymore either. I have no recommendation anymore.

Works fine in UK English too, although the "r:uk" modifier is often needed.

My point was that using an inflation calculator defers to someone's idea of what a basket was, and that may obscure the lack of data, so it might be better to study a few different things that people used both then and now and come up with your own reference point.

I'm not saying there's any alternative, ultimately, to the concept of an average consumption basket, just that methods of determining it might be different. When you have really limited data, you can look at it more closely, and you probably need to, to leverage the context because it's not going to be an unbiased sample.

> using an inflation calculator defers to someone's idea of what a basket was

In this case that someone is Greg Clark (Professor of Economics at UC Davis). The link goes direct to a .xlsx which reveals the "basket" and all the figures - it's a mixture of several (presumably average) wages and a "cost of living".

This is probably the research paper (2009) http://faculty.econ.ucdavis.edu/faculty/gclark/papers/Macroa...
