In UK companies list typical allergens in bold on the packet.

They also list whether the production line is shared with other products that might contain allergens.

This is pretty important, since food allergies can kill. (Not many, only about 150 - 200 per year die form peanut allergies in the US.)

CBC article I recall hearing a few years ago on that subject: http://www.cbc.ca/news/business/cricket-farmer-says-crop-cou...

The ratio that they give is 2:1 for feed to "meat" (hogs need 5:1, cows are 10-15:1) and for water consumption its 1/10th of traditional meats.

Glancing at the prices on Amazon for cricket flour however, its still _way_ above other protein sources in terms of cost.

Here's a crazy thought that's illegal to think nowadays. If you want to avoid crazy, illegal thoughts, please stop reading.

Maybe - just maybe - we're not all equal cyphers at birth like we learned in school. Maybe genes are part of the reason a successful person's daughter is successful. Maybe important character traits are heritable. Maybe the 20+ years we spend being raised is less consequential to our character and intelligence than who mom and dad chose as partners.

For example: IQ is highly heritable, and IQ is positively correlated with income, employment status, military rank, having a "socially desirable" job, etc. [1] Perhaps other traits are similarly heritable and correlated with the attainment of traditional markers of success.

Studies like this one on inequality are common - and useless. They ignore the genetic confound, the possibility of genetic influence on the object of study. In this case, why not look at identical twins of rich and poor parents who were raised apart in different environments?

My own suspicion is that our social rules play some role in inequality, but genes play a much larger role than is commonly accepted.

Exercising equanimity is a possible state while meditating. However, apart from equanimity, most Zen Buddhist meditations involve knowing and exercising the mind in different ways, such as applying (right) concentration and disentangling thought processes.
It's not only genetics. Parents who do well know how the system works and pass that knowledge on to their children. Children who come from poverty have a lot of learning to do and it's hard to do this without role models.
I'm talking generally about "removing the incentive", using the estate tax as an example of removing an incentive that may nevertheless be desirable for efficient market outcomes.

I'm not saying that it maps out 1:1 with this situation. Just observing that the fact that something being a positive incentive isn't sufficient to justify its persistence.

I'd recommend he read the "structure and interpretation of computer programs". It's written for audience who would, at the time, have found programming novel, but would be at home with math. Hence it's written in a language that allows you to expand out the program by pencil and paper, much the same way you would simplify an equation, to see if it works.

Thanks, I later found this paper that claims something different. Can you explain where this logic has gone wrong, they seem to start out with a similar error rate (~10^-9 per site per division):

"For example, the intestinal epithelium contains approximately 10^6 independent stem cells, each of which generates transient daughter cells every week or two. Thus, the intestinal epithelium of a 60-y-old is expected to harbor >10^9 independent mutations. This implies that, not far beyond the age of 60 y, nearly every genomic site is likely to have acquired a mutation in at least one cell in this single organ."
http://www.pnas.org/content/107/3/961.full

Edit:

>"A reasonable error rate of DNA replication (not under stress) is about 1 write error in 1 billion reads"

I think it is that you are using the 10^-9 value to be per genome while that reference uses it as per basepair

Ask HN: Connect your app to the world's networks? Is this a hard problem?
Hey,

Just wondering, how difficult is the problem of connecting a mobile app to networks so it can call normal cellphone numbers? I would imagine it could be a huge problem, due to different implementations and regulations, but I also remember there was a startup which aimed to solve this problem. Any ideas ?
Cool - that's TV on RGB. There may be improvements on the channel selection in the literature in terms of "selectivity" for real images - i.e. HSV or something else. That might be an easy change that would bump your performance.

Also you could apply some nonlinear function to calculated TV to reflect your rejection penalties - i.e. if it's greater than x make the energy arbitrarily high. The thing is you would like to then reject the whole family of solutions that had that adjacency in your annealing, which doesn't seem super straightforward to me.

The other thing I see at the end is that it hits a local optima of multiple subsets of correct adjacencies (up to reflection) but there's no way to permute those subsets to get a better solution, as the temperature is too low. You'd almost want to "group" those subsets and then rerun on the 8 or so segments just over permutation and reflection. On the other hand, it does suggest that a "greedy" approach gets you pretty close - finding a locally optimal solution solves part of the global optimization. Then you can reduce the final problem to an exhaustive search of a much smaller space.

I have no idea about prison security and how things work, but are there programmable gadgets that are allowed inside? Ie. something that is really a computer inside but doesn't qualify as a proper computer when it comes to the rules. Some pocket tetris or similar game that could be hacked to run some kind of programming environment? Some old computing gadget that runs a basic interpreter? Edit: TI calculator mentioned by someone is an excellent idea if it passes the rules.

Apart from that... reading books and solving programming puzzles might be a good way. Something that has a feedback loop, which you won't have in the normal way without a computer at hand.

Our hiring process uses only homework. We give you a problem to solve, a single Java file to do code review on and some database problems that you have to solve with MongoDB. Based on how well you do we go for a phone interview and if it goes well we bring you in for an onsite interview. I tried HackerRank a while back but it does not give us too much value. The competition going on it can be fun for programmers who like challenges like that but it has almost zero indication how well you are going to do in a production environment working on a mission critical system with a team and where your code is running on any infrastructure. Using it as a hiring tool is fundamentally flawed in my opinion.

What insanely great founders have in common
@OP: You sound almost exactly like me. I have not done any interviews for a bit more than 5 years.
I think the what really can be improved is to test us in a more familiar and friendly environment. I have to spend time on handling time-pressure, and fix/adapt with my thinking habits.

## Coding Problems:

I do think coding challenges(algorithmic) has merits, but I think there are two factor that really hinders a interviewee's performances:

- time limit

- require an unfamiliar algorithm

Time limit is obviously needed in a test, but problem solving in real life is never instant unless it's done before. Nevertheless everyone have their own pace. I have to dedicate hours each day to train myself to adjust my brain to act quicker yet calm for these algorithmic questions. Sometimes my initial solution in my mind turns out to be the best, but I discard it. Nevertheless if one is stuck, the time limit just makes it worst. I'm also known to be the slowest in turn-based board game -- I have high win rates though!

## Possible Solution?

* Allow interviewee pick from a pool of equally-difficult-challenges to solve (within a minute or two). This can solves the "obscure algorithm" or "trick" question. This also helps the time-limit problem as the interviewee WILL interpret the question twice in two different VIBES (with and without time pressure)

Even choosing 1 out of 2 would dramatically reduce nervousness and time pressure.
GCC 4.9 was a pretty big step forward.. well, atleast `g++` was.

And yet in 2016, in the face of massive blatant inequality in living standards between races, and provable systemic obstacles, you still have tons of nerdy LessWrong types talking about how it's time to own up to genetics.

Eloraam (the mod author) is working on a full game based on the mod. She claims to have started work on it, so knowing her it will be done by 2029.
Edit: I should first thank you for stating so clearly an ostensibly controversial opinion.

Collateral damage. What an interesting concept. In a sense, using technical sites for political purposes is a lot like blocking highway traffic for political purposes. Or blocking buses. Or blocking cafés.

If your basic social contract is being violated — let alone your basic human rights — no channel is superordinate to addressing that violation.

All concerns, rituals, laws, roles, rules or other social constructs must be seen as subordinate to the most foundational societal structures.

Technology is inherently political, whether it's in swords or plowshares. Trying to separate them will only deprive legitimate socio-political efforts of the network effect.

Soylent set the bar that high during their kickstarter by saying it would put you in perfect health, and was suitable for everyone.
why does the article never consider IQ to be a factor in success? in almost every success story that i come across, the story is about someone who is obviously very smart. and rags to riches stories, stories where a successful person bootstraps him or herself out of an impoverished family, almost always begin with accounts of their gifted childhood.

also, is it not obvious that social mobility is fucked? without unskilled labor, you need capital to get a nice job or start a business.
Food products suspected of food poisoning should be reported to the FDA.[1] If it involved an emergency room visit or a serious health event, call the FDA's emergency line: 866-300-4374 or 301-796-8240. Even if it's a false alarm, they want to know. If they get multiple reports, it's clear there's a problem.

There's no recall for a Soylent product listed on the FDA's recall page.[2] So this hasn't been properly recalled.

This is correct. This is also a false dichotomy, unfortunately.

Both Democrats and Republicans are for large, strong, overarching government.

Probably a Libertarian president might make a difference and actually try to reduce the powers (and expenditures) of Washington, DC, and lower the burden of regulations. Try voting for Johnson. Unfortunately, chances to elect a candidate from outside the two big parties are about zero; Trump had to basically hijack the Republican party at its all-time weakest to become a real candidate.
As I said, knowing Eloraam, it'll be done by 2029.

Mod looks cool, though.

I'm going to defend the issue raised by the (deleted) slide:

> Why do you fund ... companies ... which have no clear (to me) business model?

It's a great question and I used to wonder it myself.

Consider it in the engineering domain: companies get investment to do development. Some may have only an idea, some may have a prototype, some may have a product and need money for growth (these get the highest valuation as they have the lowest risk, but also tend to have the lowest returns). I don't think any of that should surprise anyone.

Well; companies appear in the same distribution of states in the business domain. Some, like Google, have no business model in mind and almost fail because of it. Some have a business model which does't look well baked but the entrepreneurs seem to understand it, so can probably develop it into something worthwhile.

And of course there are there ones where the investors want to know more about the sector. Open Source <insert XXX here> was like that back in the late 90s.
I find this curious. How do typical flight sims respond to trim wheel and how does that differ from what you expect?

When I do flight sims, I rely on the pitch trim wheel a lot but I've had very little time at the controls of real aircraft so I don't know how should it feel.
Fermi estimates require at least some knowledge of the quantities you're using as inputs. Are the students expected to know these, and tested on that, or are they allowed to state any values they like for the inputs? Do the teachers and the test-writers think only the process is important, or the results as well?

For example:

> How many molecules from Socrates’s last breath are in the room?

We can estimate the number of air molecules in the room by using Avogadro's number (6.022e23), the rough chemical composition of the air (roughly 80% nitrogen, element 7, and 21% oxygen, element 8), and the room's volume (which can be hard to estimate by eye unless it's a very small room).

We also need the total mass of the atmosphere; we can estimate it from the Earth's surface are and atmospheric pressure, but we need to convert 1 atm to kilos per square meter. Would an average student remember that conversion rate? I certainly don't. (Turns out that 1 atm ~ 10,330 kg/m^2).

That's quite a few constants to remember from physics and chemistry.

(I'm aware that Fermi estimates are only one of many kinds of example questions in the post.)
It's popular to embed a prolog in Lisp languages. For example Picolisp and Shen. I wrote a post comparing Shen's Prolog support to SWI Prolog recently: https://bluishcoder.co.nz/2016/08/30/kicking-the-tires-of-sh...
Had no idea this was the culture inside Snapchat. Bad sign that he models himself after Jobs - Jobs anihilated product after product for 25 years until he finnaly got it right. He did that by assembling a team of people who would argue with him and win (his words). He needed people around him to curb on his own worst impulses, and he needed decades to figure out who, why and how to do that. And the only reason he succeeded at even trying to do that was because he met Woz and they built a computer together, which made them both millionaires very quickly.

Yes he was very sucessful. But it took him decades to learn how to do that, and he "learned by doing" by screwing up the original Macintosh launch, NeXT, even Pixar in the beggining . It was Catmull, not Jobs who made the difference there, and Jobs learned from Catmull
Is your software open source or available, it looks like it's python from the video. I want to buy your kit, but I'd like to build a robot that drives around my house while we are out, with a camera. So I would want to be the only one with access to the camera, turn it on when the alarm goes on. I a dev, I can hack python just fine. The reason I haven't done this myself is all the work to get to the hardware, and basic software.

Guessing the software arch, you encode the video on the robot and then send it to your backend site. Then you have a separate listener on the pi, that just takes single commands from the website. I imagine not running a webserver on the pi makes the response much faster and doesn't run down the battery. So for a private webcam in my house, a kind of alarm system, i need a system there to capture the video stream and act as a remote host that I can access from outside. I don't want to copy your webserver stack, I'd prefer something lighter weight, that I could run as a service on a linux or windows pc.
Currently he's wanting to learn everything he can and specialize later, but we have discussed him building a web based platform for an idea he has. But generally he sees everything moving toward software and he wants to be prepared, which isn't wrong. Thanks!
