I think it's more likely that more people are becoming obese because of exactly one factor: age. They are living artificially prolonged lifetimes due to access to adequate food and to medicine. It's easier to get fat when you are 50 than when you are 30 because of the natural changes in your metabolism.

:-)

You make it sound like starving people are getting fat too.

If they are becoming obese, the particular individual has a surplus of caloric intake, if only for this year or month. This is not to say that they have proper nutrition. So I am not at all clear that the fact that there is obesity in the third world is confounding evidence.

For most of the existence of mankind and indeed all of mankind's progenitors, having too much food was a rare problem and being hungry all of the time was a fact of life. We are not necessarily well-evolved to handle it. So, no surprise that we eat to repletion and are still hungry. You don't really have any reason to look at it as an illness caused by anything other than too much food.

Martin,

The last time I had a professional video produced, I paid $5000 for a one-minute commercial, and those were rock-bottom prices from hungry people who wanted it for their own portfolio. I doubt I could get that today. $8000 for the entire conference is really volunteer work on Gary's part.

Someone's got to pay for it. One alternative would be to get a corporate sponsor and give them a keynote, which is what so many conferences do, but that would be abandoning our editorial independence. Having Gary fund his own operation through Kickstarter without burdening the conference is what we're doing. We're really lucky we could get that.

We do charge entry to the convention. We get really nice facilities for the people who actually travel there and for the speakers. Last year's location was subperb. But I don't see why they should actually subsidize the folks who do not attend.

I think TAPR's policy is that the presentations be freely redistributable, but I don't know what they and Gary have discussed. I am one of the speakers and have always made sure that my own talk would be freely redistributable. I wouldn't really want it to be modifiable except for translation and quotes, since it's a work of opinion. Nobody should get the right to modify the video in such a way as to make my opinion seem like it's anything other than what it is.

If I remember correctly, it was 4 video channels last year: tracking on presenter, proscenium, audience, projector.

Yes. I put in $100, and I am asking other people to put in money to sponsor these programs so that everyone, including people who did not put in any money at all, can see them for free. If you look at the 150+ videos, you can see that Gary's pretty good at this (and he brought a really professional-seeming cameraman to Hamvention, too) and the programs are interesting. Even if at least four of them feature yours truly :-) He filmed every one of the talks at the TAPR DCC last year (and has filmed for the past 5 years) and it costs him about $8000 to drive there from North Carolina to Austin, Texas; to bring his equipment and to keep it maintained, to stay in a motel, to run a multi-camera shoot for every talk in the conference, and to get some fair compensation for his time in editing (and he does a really good job at that).

I am interested in watches.

Whether or not a smart watch is worth it is an open question. If they can provide me something that I think I need with it, then sure. I've outlined a list in comments on previous stories, for quasi-trolls that were about to lash into me for being so general.

But I wear an automatic mechanical beater right now—specifically because it's virtually indestructible, represents only a minor investment (and thus financial risk), and requires no maintenance, attention, or battery-swapping. It's accurate to about 2 minutes per year, which means that about once a year I tune the time on it.

Most of the stuff that smartwatches are currently being said to do I either don't care about (fitness tracking, health monitoring) or currently use a smartphone for with far less hassle (bigger screen, more natural UI) so it'll be a stretch. But I'm open.

Journals aren't arbiters of Truth (capital T), they're just what they say they are: JOURNALS of the ongoing work of science.

Someone records that they have done X in a journal. Because said journal is available to other scientists, other scientists get to try to make use of the same notes/information/processes. If they are able to do so, they journal it as well. Get enough mentions in enough journals that something works, and we can begin to presume that it does.

If only one mention in one journal is ever made, then it is just another record in another journal of another thing that one scientist (or group of scientists) claim to have done.

Peer review is just to keep journals from expanding to the point that there is too much for anyone to keep track of or read. It is emphatically NOT the place at which the factuality or truthfulness of notes/information/processes are established once and for all. That happens AFTER publication as other scientists get ahold of things and put them through their paces.

Seriously, this is all exactly as it is supposed to work. I have no idea why there is such hoopla about this. There is nothing to see here. One group journaled something, other groups couldn't replicate it, they no doubt will reference this failure in future articles, and "what happened" is recorded out in the open for all of science, thereby expanding our pool of knowledge, both about what consistently works in many situations and of what someone claims has worked once in one situation but appears either not to work in the general case or requires more understanding and research.

Again, there is nothing to see here. Let's move on.

this would seem to be moot to me. Humans have only been here for the briefest of very *recent* moments, but we do have a particular interest in keeping earth habitable for *human* life.

Assuming your numbers are correct, it still doesn't do us any good to say that gosh, a few million years ago there was a lot more carbon dioxide, if for the purposes of *human* life a particular (and lower) level is necessary.

The goal is for us, not for the earth itself, to survive.

1) Monitor and keep and continuous chart of blood glucose, sleep cycles, blood pressure and pulse rate, blood oxygenation. Don't even know if the tech is viable for these, but they'd interest me.
2) Be part of a payments system that actually gets traction out there. Let me import all of my cards of various kinds and then provide them wirelessly to others without having to pull out a card (and/or a phone with a specialized app).
3) Same thing, but hold all of my tickets for entry into events.
4) Connect to a voice-to-text service to enable personal logging/journal-keeping just by talking at it.
5) Find a way to operate clearly and reliably using gestures and voice recognition rather than touch input when desired.
6) Have built-in GPS and voice navigation.
7) Have a built-in high-resolution camera to enable convenient visual capture of information.
8) Do all of this in a cloud-based manner so that everything that the watch did/tracked was available from all of my other tech devices.
9) Have a between-recharges time measured in weeks.

I don't know, it would have to be pretty freaking fabulous. But there are some basic things that I *don't* care if a smartwatch does, and those are probably more telling. I absolutely do not care about doing these things on a smartwatch:

1) Calls
2) Web
3) Email
4) Facebook
5) SMS
6) Linking it to my phone via bluetooth
7) Telling time

Number 6 in particular is a non-starter for me. Battery life on phones is already too short. And phones are the devices that I use for web, email, and other informational tasks on the go because they (not a smartwatch) have the screens suitable for reading/editing. I need them to last as long as possible, and I have no interest in duplicating their functions on a smartwatch. So I refuse to enable bluetooth on my phone all the time just to get some additional "watch" features.

It needs to be a "standalone" device in the sense of no other devices needed for it to operate normally, but a completely cloud-integrated device in the sense of "but I can access everything it does and it can access everything I do on my other devices over the network."

Number 7 is also pointedly interesting. I don't care if something on my wrist can tell time. Social "time" as a concept is more ambient than ever. Everything has a clock on it. Your computer. Your phone. Your thermostat. Your radio. Your car dash. Every ticket machine of every kind, from movies to transit to events. Public spaces and the sides of buildings and billboards and retail shop signs. I don't look at my wrist or my phone to know what time it is. I do a quick visual 360 and in general, I find what I'm looking for, wherever I happen to be. A "time-telling device" is frankly a bit 19th/early-20th century a this point.

Remember when we had a Debian system on the biosciences mission? They scrubbed the whole mission after they were already in space due to a fuel-cell issue that I think turned out to be a faulty sensor, and flew the entire mission a second time.

maintainability and "correctness" from the CS class perspective aren't important. Are the data and data processing valid, and did the job get done as quickly and as cheaply as possible—that's all that matters.
