I miss the good ol’ days of Minitel. Imagine an internet made up almost exclusively of French people.

How expensive was it to participate in message boards. My parents used it so sparingly and with the idea that any minute was addding up. I read 60 francs l'heure, so about 10 euros or more like 17 with inflation. Even spending an hour a day would be a costly hobby.

If you have the skills, you should definitely try it.

We have a full team working on this for about 7 years. Constant improvements to our algorithms, new challenges, new technologies. A ton of other functionalities besides counting (e.g. forms, reports, integration). A lot of work on the backend, UX. Also, a lot of sales and marketing involved.

It is impressive you do it so fast. In case you have not thinked about it, some people will be interested by it in life sciences. Best I could do with the picture available on your website https://imgur.com/a/FKEkiFz compared to https://countthingsqanda.com/wp-content/uploads/2021/01/5-17... I got some wrong counts but the picture is really tiny to work with.

Hi, there! I'm one of the project managers at CountThings, I'll try to respond to comments here but I guess you can AMA.

Is not it something anyone can do for free using image J with a bit of scripting.

False positive rate of some antibody tests is 9%, which makes any effect size below that invisible.

It would be the test using QPCR to amplify the virus genomic material from samples collection. That test is a lot more specific though there can be issues with how the samples were obtained.

I am not in any way qualified in the medical domain but these methods look similar to the other Study that was viewed as flawed that showed it did work. Seems there is no solid data either way.

malpighien · 6 years ago

Well this one seems more rigorous. They monitored concentration in blood for 4 days, they checked viral presence two following days at the end. They don't mention viral load though and I don't know if they have a threshold for cycles in QPCR to estimate that. This kind of paper is not here to say here is the proof it works or it does not work, it is meant to say: this what we had with us, this how we did it, this is the results we observed and whether or not it validates the hypothesis stated.

Storage doesn't have to mean batteries. I'd have thought approaches like pumped hydro [1] could scale pretty well. I vaguely recall a similar story from a couple of years back that basically involved lifting giant concrete blocks.

If those solutions were viable at scale then countries like germany or england using lot of renewables and coal (gas or gb) would have been using them already.

You still need storage when you go 80% renewable, so any extra production by renewables can be used to generate hydrogen or charge batteries or something so that the nuclear plants can still sell their energy. It's not like they don't get any subsidies today, there is no reason why they shouldn't get any in the future.

It's just a question of what is cheaper or faster to achieve. I don't know enough details to say either way.

malpighien · 6 years ago

I don't think here are available storage solution for renewables and even if there was it would need to be a solution scalable without a risk of running out of resources to make the batteries. Renewables are great but they work on the shoulders of nuclear/coal which need to pick up the load when there is no sun/wind. Renewables feel like paying more for getting less with different but not necessarily less pollution issues.

quickthrower2 · 6 years ago

This could be placebo. Anything related to sleep or headaches there could be a psychological factor ie because you “know” blue light is bad it becomes a self fulfilling prophecy.

malpighien · 6 years ago

Is it possible or ethical to offer a research option to f.lux? Like you would let the user pick that option and have the software dim the luminosity with or without cutting more specifically blue light then have them report and if they felt any difference after a week/month or a month, repeating the process for a few months/week while either alternating or changing the mode.

Maybe it is a dumb idea as it is too easy to tell whether the software is in full effect or not.

Hi, author here! Didn't intend for this to wind up on HN quite yet, but I'm excited to answer the good questions coming up here.

malpighien · 6 years ago

Question from a completely clueless perspective. The points you mention I always have and I have been wondering where to simulate it and get numerical answers to all those behaviors that can be infuriating. In your seattle full map you say you heuristically got the time for the lights, but where is that coming from exactly, like would it be possible to infer that for another city from some kind of public data. Is it in the domain of science fiction, there are so many parameters to take in account so it probably is impossible, that you could model the usual behavior of commuters in a city and then simulate whether the current traffic lights are set for the right length of time. I suppose some are updated live to react to traffic jams but in these circumstances there could also be way to simulate how shifting times would be the best to refluidify the traffic, instead of just going with brute force and empirical intuition which I assume is how it works most of the time.

Wow. That was a remarkably balanced article on climate change.

malpighien · 6 years ago

Is it, he constantly mixes aspect of climate change that are unrelated to each other and claims they are the same to say that concerns about the long term effect of climate change are overblown.
