My SO had fMRI done before her first brain surgery for glioma that was located near speech center and motor cortex.

It wasn't a big deal, so I think they apply it routinely in some cases in their practice.

I'm not sure if they got much from it because it was really low res in comparison with standard MRI.

Although she made a full recovery after that surgery.
I'd say you'd have to launch at least one highly successful payment service first then move on to those other things.
> Physicists, on the other hand, didn't invent physics, so they know their current understanding of physics could be wrong.

Technically, yes. but not in the sense that the word "wrong" is generally used. Existing measurements confirm that the current theories are mostly correct to high degree of accuracy, and over a lot of measurements, in a wide range of circumstances.

Current understanding may be proven _incomplete_, but it won't be superseded by something completely different that contradicts those measurements. That would be a non-starter, but it's what people think of when they hear "x is wrong".

e.g. Newtonian mechanics is "wrong" or "incomplete", but it gives very good answers for everyday circumstances. Just not for very small or very fast.

Why did poetry die? Because it migrated away from rhyming metrical poems that sound good (eg William Blake, Robert Frost) to basically abstract prose with carriage returns. However demand for the good stuff did not vanish, it’s now just satisfied by pop music, with the academic poets publishing in irrelevant chapbooks.

Same exact thing happened with classical music. Stuff like Bach, Beethoven, Vivaldi, Debussy, Tchaikovsky... the stuff sounds good. That might be obvious... but nowadays sounding good is extremely passé and if you write stuff that sounds good you will never get tenure as a composition professor. But people still want orchestral music that sounds good, so the people get what they want in film music like John Williams, Hans Zimmer, and Howard Shore.

We have months because there is a big celestial body close to our planet that helped humans track long-scale time since before any formalized time system, so we had to fit it in, but on Mars? Even though there are Phobos & Deimos (which orbit too fast for any similar long-scale time tracking practical purpose), how visible are they to a martian surface observer with unaided aye? I guess that indeed there probably won't be anything, or at least not something local for that time-scale.
Hi all!

TL;DR

Walkability is an increasingly important aspect of our lives, so my friend and I built a tool to automatically measure it.

PROBLEM

* Walkability is important to people [0], and the planet [1]

* The existing solution, Walk Score, is flawed [2], seems to only operate as the crow-flies, and is missing key info, such as traffic safety [3]

SOLUTION

* My friend and I built an MVP to reflect recent academic literature [4] and provide a more detailed breakdown

* It’s an MVP to see what users think. The scores still need a lot of work.

EXAMPLES

1) 1000 Largo Center Dr, Largo, MD 20774, USA

Link: https://walkable.us/result/1000%20Largo%20Center%20Dr,%20Lar...

Image (in case site is down): https://i.imgur.com/cEik22U.png

2) Langley Park, MD, USA

Link: https://walkable.us/result/Langley%20Park,%20MD,%20USA

Image: https://i.imgur.com/6CiyFIa.png

IMPLEMENTATION

We reached a 100ms single CPU response time for any location within the US with the following:

* OSM data from GeoFabrik imported with imposm and pre-processed with osm4routing

* Data lives in a PostGIS DB with pgrouting and post_raster extensions

* Entirely route-network based walkability computation using OSM POIs, regions and edge data

* We achieved high speed in general by moving as much computation as possible to PostGIS - we were blown away by this toolchain!

* We use a PCA based model for the overall score, with range based breakdowns [5]

* Bing building footprints helped overcome OSM data paucity issues [6]

We hope you like it. Please let us know what you think!

Java has a new DateTime and related classes, that I believe solves every(?) problem with the old Date class.
Most people afraid of “math” only have exposure to the second kind. I figure it has more to do with finding those type of mechanical operations boring (they are), and hence all of maths must be equally boring. If you’re a software developer, enjoy abstractions, programming language theory, and solving problems there is no way you would find math of the first sort boring. Alas, in high school pretty much all the math is of the boring mechanical kind. At least mine was, anyway. Even the first exposure to non-rigorous calculus is of the shitty plug-and-chug variety.

as a proof of what I've written on the parent comment, I made the usual mistake yesterday: I commented on a thread about bitcoins writing that no, btc won't save the World and no, very few people got rich, btc are not making the general population rich.

Of course I received a couple downvotes, that rippled over my previous comments on completely unrelated topics, like this one, just because my other comments where more than 24 hours old and they couldn't be downvoted as per HN rules (the parent comment was already 15 hours old when received the only downvote - meaning nobody cared for it - at the same time of the btc thread that was fresh).

> You cannot downvote comments which are direct replies to your own comment, and you cannot downvote 24 hours after the original comment was made.

If downvotes where ided, it would be obvious that the downvotes on the comments on this thread were just retaliation from the frustrated owners of bitcoins whose propaganda was being questioned.

The id doesn't have to be the real useranme, it could be a random id that identifies a user for a brief period of time (48 hours) so that other users could report the issue, knowing that it's not their paranoia, but a real thing.
I'm not sure if you described usage or capabilities, but if the latter, these can be done in excel:

- named references - set a range name and you can use it in formulas

- functions - macros can export functions

- sql-like views - power query

It's still all pretty shit, but unless you need to support old versions or Mac Office, there are workarounds for some stuff.

Huh? Cython tries, but it's not exactly optimized hand-coded C. And it works better for some things (e.g. numerical typed code) than others.
Now it just needs to charge / run from solar and it can be dropped anywhere with signal. I wonder what sort of wattage this thing draws.

>"Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances.[1]"

[...]

>"In alchemy, calcination was believed to be one of the 12 vital processes required for the transformation of a substance."

[...]

>"In some cases, calcination of a metal results in oxidation of the metal to produce a metal oxide.

In the seventeenth century, Jean Rey noted that lead and tin when calcinated gained weight

, presumably as they were being oxidized."

PDS: Ah, but...

Were lead and tin in fact being oxidized -- as Calcination refers to "heating a solid to high temperatures in absence of air or oxygen" ?

(The Wikipedia editor's presumption of oxidation -- contradicts the definition of Calcination!)

Or did they gain weight anomalously, without air or oxygen present?

?

You see, this would be a great future research project...

The smaller, less important thing that we are looking for -- is if lead or tin actually gained weight when heated in a vacuum...

The larger, more important thing that we are looking for is:

are there any anomalies that are known in Chemistry, that is, where the actual results of a chemical reaction or reactions -- differ from what's expected?

In Chemistry (as well as any other science or system of logic!) -- always search for the proverbial "Minority Report"...

Then do your own testing, and see if it's true...

Then if it is, try to figure out WHY...

Actually no, if there are 10-20k people like me only driving a few thousand miles instead of 10-20k miles per year we'd be much better off! (which btw is the average in the US)

You aren't going to shame me over a few miles when I make a concerted effort to drive 1/10 of the average American, sorry.

But hey good news, Google is abandoning remote work and making its employees drive to and from work every day probably negating any benefit from this feature whatsoever.
And a solution that would require code change isn't nice either, as rekeying equipment and spreading the public keys around is a huge logistics ordeal. These problems are never as easy as "pulse some light with some crypto on top". Hell, the very existence of an active IFF signal is already something that distinguishes you as a military target, so the enemy could just use your IFF as a homing beacon.
If you want a city for enjoyment then realize that this is something only the rich can afford. The poor don't have enough money to afford an increasing level of luxury.

Next, Simple Promise VivaSlim has many amino acids in its ingredients list, which help build lean mass and lose fat. According to some studies, the branched-chain amino acids (BCAAs) used with vitamin B6 can affect fat breakdown, muscle growth, and lean mass gains. But for that, they need a higher amount of BCAAs, which is impossible to get from dietary sources alone. Hence taking help from a supplement may increase the amino acid intake, making it easier for the body to avail all these benefits.

I agree with what you said as one possible path to "why", but one look at the history of the Bradley Tank shows how meaningless time/money can be in large orgs. Especially political ones.

Couple this with big name/external validation, and the fact that the best and brightest techs don't flock to the military (too dogmatic)...

The F35 is the new Bradley tank, and how much was spent?

Anyhow, you're probably correct, but I take exception to the reasoning being how much the military spent, or how long they worked at it.

(note: In times of war, all the political jockeying ends, disappears, and the military becomes lean and efficient. In times of peace, politics exist, including funding games.)
