Thoughts on countries like Japan with a super-aged population but with low fatality ratio?


Culture of discipline. If government says you to wear masks, you don't run a rally because not wearing a mask is your "human right". You wear a mask.


They just announced there will be live streamed game(s) after Mana's series.


Does Stripe (presumably where they work) still allow full-time remote work? I looked at their job board and it seems like none of the job posts are for remote positions.


I can't speak for the job board, but there are dozens of full-time remote developers (including me, obviously), and I see remotes devs being hired frequently.


I've never used Go, but would you write your customer facing REST service using Go? Or would it only be used for back-end microservices? What's a recommended library for writing a customer facing REST API?


My data structure wish list:

- heapq to support max heap better. (you can invert the value or use heapq._heapify_max, neither is ideal.)

- Tree map.


This resonates a lot with me. Whenever I participate in a social gathering there are already long-established "cliques" and they just talk among themselves. I feel this especially at wedding receptions -- I find myself awkwardly walking around while everyone is chatting, and I'm just wasting time until I feel ready to make my irish exit.


Any hints of which states you invest houses in that are cash flow positive? California seems to require ridiculous capital to even get started.


Second and third tier cities and areas in the Midwest are usually better. Sometimes you can do OK in suburbs as well.


Based on my research, you would look for areas that have a strong work environment, geographical limitations that help (a river restricting how many units there are or can be), and so on.

But based on my experience, I would recommend you just keep looking. We have a fourplex in California, it cashflows about $200 per unit, but part of that is due to the healthy down payment we put up. And this is in an economically depressed county, the work environment is so-so, _contrary_ to my research mentioned above.

Due diligence is the key for us. I optimized on "most income potential for the down payment," then ended up paying extra because the previous owner had a firm line in the sand and someone else was also interested in the same property.

Thanks to phantom cashflow (depreciation) and the repairs we make here or there, we put money in our pockets but are able to show the IRS a loss during _some_ years, based on the US tax code (conservatively legal).

I have been corrected before on HN about "too good to be true" numbers, so I do need to point out YMMV. We were beneficiaries of being in the right place at the right time, but we also spent the previous years getting ready: reading books on residential rental real estate investing (note the specific angle there - many ways to make - and lose - money on real estate, be specific), cleaning up our credit reports, building up a down payment, learning the local markets so we could buy something local and keep an eye on our first property, learning about property management and being landlords, meeting and interviewing prospective property managers, meeting and interviewing prospective real estate agents, and then setting up the correct legal entity to hold the property in. We hired a coach after the first purchase, and had much of the same learning material, but far more compressed - We went over in 6 months what it took me 3 years of research to get on my own. And that does not include the invaluable tips one can get from someone who already walks the talk.

We also evaluated at least 10 properties in person that did not pass muster, and that was after weeding out scores of properties that we did not even bother to visit.

We had a few deals fall through, but usually because something was not good enough, usually not enough return on investment, or too much deferred maintenance (requires deeper pockets to get in, but can be more profitable in the end - IF you know what you are doing. And have a good team.).

This specific deal earned us %13 - Not great, but definitely better than other deals. I have a friend who would not look at deals unless they had %28 ROI or more in them, but then he also talks a big game :)

But it IS possible. In fact, thanks to the elastic property of real estate negotiations, it is a place where you can still get in with nothing down every once in awhile, but one really has to be prepared for those deals when they come through.

Besides location, location, location, I think the bigger catchphrase should be financing, financing, financing. There is a lot to be said about the art of negotiation, when it comes to a buy/sell agreement.

But again, YMMV, and I only got out of it what I put into it in sweat equity, as well as capital.

And, we are still learning...

We also own a rental in Florida, but that is a whole other story...


> So the biggest barriers to doing it on your own aren't source material (there is lots of that) it's a good source of correction.

Does anyone have any recommendations for where I can find a "good source of correction" (private tutor) online or locally for discrete math/algorithms/college-level mathematics? I looked at WyzAnt which gave me no results for my area -- most of the tutors seem to be for SAT/high school prep.


I fail to see the benefits of using this over keyboard shortcuts, mouse, and a wacom tablet (many keyboards and tablets also have programmable buttons.) My setup is currently keboard + mouse on a keyboard tray and wacom tablet on the table and I have never felt a need to turn a dial for lack of precision. I guess it's an alternative though?


Just curious, but any chance of Khan Academy adding Discrete Mathematics? Correct me if I am wrong but I don't think coursera/udemy have a course either. The only free online course I am aware of for Discrete Mathematics is MIT OCW 6.042J.


I don't think we have any immediate plans for Discrete math - we are still filling in gaps in our K-12 curriculum. We'll see, maybe someday!


For what it's worth I would absolutely love a discrete math course from Khan academy.


It seems like Khan Academy initially covered whatever Sal Khan found interesting, so there is Calculus, Linear Algebra and Differential Equations. Now that it's become more focused, a side effect is that there's a bigger concentration on grade school-level stuff.

It is a pity though. It would have been great to see KA covering Theoretical CS as well as Discrete Math.


Descrete Math is so important to understand the analysis of the algorithms (esp. a new problem). However, I did not find any useful course except the one you mentioned.


Berkley's Discrete Math class is solid. Lectures on Youtube: http://www.youtube.com/playlist?list=PL-XXv-cvA_iDTidF2dnVq_...


This looks latest (fall 2014). Thanks :) Will try it out, I was looking for descrete mathematics course almost 2 years back and could find only MIT one. Good to see some options now.


MIT also has a pretty solid discrete math course on OCW (I admit, I only watched the lectures, but they were a good refresher for me going into interviews).
