Ask HN: Website with graph based knowledge management
A while ago I saw an online learning resource. Topic, IIRC, something around maths/computer science, maybe machine learning.

The cool thing about it was, that it was organized through a graph: Basically, a visual, more abstract version of wikipedia-like linking. You could see where you are and decide where to go next, along links, to related topics.

Anybody knows such a website? I could not find it anymore.

With a Cuckoo’s Journey from China, a Mystery Is Solved, and Cheers Go Up
"QC in some countries appears impervious to consumer feedback; they couldn't produce a decent set of pliers 20 years ago and they cannot today. They may never succeed due to their unique social and political histories."

Would you provide some examples of the countries you're thinking of? My inclination is that it's more a function of demand for cheap products and unwillingness to pay more for better quality even while complaining about the quality of what some are willing to pay for. Also, the generalization that all (or most) products coming out of a country are of equal in quality. Two counter examples come to mind as well. Japan and China have both been a source of cheap, low-quality goods during the last century, and both also produce some very high quality goods as well. I've also purchased very low-quality "Made in USA" products.

And things change, including "unique social and political histories". Is it more accurate and useful to think of differences in QC in a general way or to look more closely at the incentives and circumstances at work?

If I've mischaracterized your views, please do point it out, as that's not my intent. Thanks!
That makes sense. But then I guess my question becomes: at what point are you spending so much time and effort learning advanced features of spreadsheets that you could have become proficient in one of the tools with a higher ceiling?
This is what I was going to say as well. Don't jump into "boot camp", start taking night classes at your local community college (or if you have flexible hours) day classes. Even MOOC/online classes during the evenings will be a path to adding coding skills to your resume.
Yes and no. My question is, what do you want to achieve by going through a boot camp? Using the certification as a pivot for career change? Having an short period of time where you can focus and intensely study the subject? I think it's important to consider what specifically about the boot camp route is important to you, because there are a lot of other ways to be proficient in coding.

Tutorials on various common "patterns" (RoR web apps, iOS apps etc.) are of good quality and easily available these days. As a PM in big tech, you can try to find little ways to contribute into the product's code base, which will teach you both programming and engineering practices. In my experience (disclaimer: was a PM), engineers are delighted when PMs show interest in code, and at least a few would be excited to hand hold you through the process of setting up your dev box, building the product etc. It's not a bad way to get better while making hand and fist full of money.

That said, like any other craft and practice, programming is layered and specializes. It takes 5-10 years to be "good", and it takes equals amount of time to be good in a specialization (say machine learning for example). Even for a good ol' engineer to move from building web apps to building machine learning systems, the barriers are still non-trivial. Furthermore, consider that a career in software engineering is perhaps more akin to spending 20% of your time building somewhat sexy* new thing, and 80% of your time doing boring boiler plate work, trying to pull your hair out digging through other people's APIs and code, and wondering why the build and CI system is so broken. If that's what you want to do, then go for it.

* most likely it's just a boring CRUD app using somewhat unfashionable technology.

Can you provide evidence of this? I know a lot of Democrats, and I don't remember any of them ever saying a positive word about the PATRIOT Act. Certainly, those actually in power are always reluctant to give it up. But I haven't seen that applying to their supporters in the particular example you cite.
Thanks, I didn't know that!
5 Programming Languages to Learn?
"That's not the way the law works though. You don't get to decide which ones are worth following."

You do. See: civil disobedience.[1]

Also, just because something is illegal doesn't mean it's wrong. A simple example were the laws against helping runaway slaves in the US. Many today would agree that helping runaway slaves was the right thing to do, but yet it was illegal. There were similar laws against helping Jews in Nazi Germany. Once again, just because you broke the law by helping a Jew wouldn't mean you did the wrong thing.

That's not to say there's any sort of moral equivalence between people (allegedly) breaking laws by participating in Uber or AirBnb and those who helped runaway slaves or Jews in Nazi Germany. They're just examples to show that breaking a law need not automatically be wrong, and that doing the right thing can be more important than obeying the law.

Finally, there are plenty of examples of stupid laws and outdated laws. Laws against sodomy or against dildos over a certain length spring to mind. Both of these existed relatively recently in the US (and possibly still exist), but they were pretty much ignored, and few people would have considered themselves to be in the wrong if they broke those laws.

I agree. But regarding privilege, I'd argue that not having to fear for one's freedom is part of 'privilege'.
Sounds like the second amendment...
Point taken. But I'm not sure that liberals (myself included) embraced centralized government for its own sake. It could have been a simple matter of opportunism: If your state won't budge on rights, and the central government will, then the central government becomes the way to expand rights.

Likewise, I'm not sure conservatives really care so much about decentralized government, but are opportunistic about the effectiveness of influencing state and local governments.

An interesting aside is that in my state, the (nominally) conservative state government is enacting laws saying what kinds of ordinances the cities are not allowed to pass. A piece of land not far from my house was declared by the state to be exempt from local zoning.

So I think the preference for central or local government power is a matter of opportunism that is chosen on a situational basis.

This is the best comment so far. Bootcamps make sense if you have spare time and spare money and want to ramp up very very quickly, but they don't provide anything you can't learn on your own. This is doubly so if you are already working in tech and interact with working programmers who can help sanity check what you're doing and help you along in your studies.

I understand how having some social structure helps one learn, but I've often seen this misapprehension from PMs and MBAs that you either "know code" or you don't, and if one can just cross this chasm then all of a sudden you can be the one building things and realize your own vision. But in reality you won't be a good coder unless you have the tenacity to keep learning continuously over years and decades. Self-learning is not only free, but it's a good litmus test for this tenacity, and there's a huge amount of resources out there that make it trivially easy to get started.
Reasons to use Uber:

- I take out my phone, enter an address, and five minutes later a car picks me up.

- I take out my phone, enter a time and an address and right at that time a car arrives and picks me up.

It isn't that complicated. Could taxi companies adopt these innovations? Sure, and now they are. Why didn't they before? Because they are government protected and didn't need to.

If we all just accepted the economic structures the government licenses and supports France's minitel would still be the coolest network on the planet.

This article has all of the hallmarks of something cranked out as fast as possible to ride the WTF wave, with little to show and mostly a collection of anecdote and refs to the work of others.

NVIDIA's Drive PX 2 has too high power consumption and too low perf/W for the moment. They're winning this space because they are there more than that they are the best possible solution.

And they may continue to win because successful execution of an 80% product is worth far more than a 90+% powerpoint processor cough TenSilica et al. cough, or because this is such a huge potential market, it might actually go to a successful competitor. 2018 and beyond will be very interesting.

For while it's really desirable have the deep learning equivalent of x86 assembly language (CUDA) across a full stack from training to inference, in the end, IMO cost will be king. I'm not a big fan of $150K high-end servers filled with $5000 GPUs that can be bested with clever code on a $25K server fill with $1200 consumer GPUs. But I am a huge fan of charging what you can while you are unopposed. It's just that I think that state is temporary.

> Uber plans to do away with human cab drivers.
It would be easy for a non-plutocratic government to prohibit this, and that's what every country ought to do, unless/until every person gets an adequate basic income so people don't need to be employed.

This looks like complete Luddite statement - i.e. Uber must employ humans as drivers and government must prohibit driverless cars until there's no need to work for anybody at all. For me this sounds insane. Why don't ban bulldozers then or ATMs or factory automation or, for that matter, power looms? Until everybody gets basic income and nobody needs to be employed?

I mean I know it's Stallman, but I didn't expect him to also be a technophobe...
I've been informed that crashes+corruption indicate either lack of memory or hardware faults. Bitcoin needs to do an awful lot of cryptography, and it all needs to come out perfectly for it to work, so it tends to be sensitive to hardware faults.

> just try a load of stuff and pick the one that works best

Well, yeah, that's easier to say than "read this entire book to understand how machine learning models work". The truth is that different models work with different success for different kinds of data.

How many predictors do I have? How many observations vs how many predictors? How much data overall? Do I care about interpretability? Am I doing classification or regression? If doing regression, what is my tolerance for error? How much time am I willing to spend training and predicting? If doing classification, are my classes balanced or imbalanced? How are the classes spread? Do I care more about overall errors or false positives / false negatives (think of a cancer screening test - you might rather have false positives than miss something with false negatives).

All of these factors, and more, go into play when selecting a model. There's other bits too. Selecting variables: including unneeded or highly correlated variables can actually worsen the result. Feature engineering: Turns out you might be able to process your variables in such a way that the algorithm picks up on the details you need much more easily. Cross validation: You don't want to "overfit" your training data, i.e. get a model that is super specific to your training data such that when encountering actual data points, it has worse accuracy because it's not general enough. Hyperparameter tuning: Usually a lot of these models have tuning parameters that you can tweak, that are hard to know what the values should be from the get go, and you have to try a bunch and look at the response curve of how the accuracy changes.

So yeah, machine learning is not magic. Turns out there are different tools for different problems. We do have some models like Random Forests and SVMs that work fairly well out of the box on a wide variety of problems, and some kinds of neural networks also do well but often need more data and processing time to get decent results. It's all a tradeoff :)

If you can come up with a profitable strategy then you can still be hired or just trade yourself. Without this there is no point being a quant. Besides quants still need developers - those integrals will not help building maintainable trading apps.

I would say those questions are for recent graduates who want a junior quant role.

Totally agree. His personal/family life is a shambles which is a real litmus test of character and integrity.

He has achieved great financial, business, and technology successes and is a visionary, but let's not confuse that with being a role model or hero to be emulated.

Stallman on the other hand gets nothing but respect from me for his personal integrity and values.
There's a difference between bragging and actually doing something. Trump brag that he's so rich, women would let him grab their pussy. Women would LET him grab their pussy.

If you want to become a dev via this route, right now that is a risky move and a long road to real expertise that would carry you through an economic downturn where very junior people are let go. If it is your passion to be a dev, maybe, but expect it to be difficult. Maybe just consider going back to a proper university for that CS degree you probably should have gotten to begin with?

If you want to become a much better PM and have the tools to start building apps on your own, then yes DO IT! Right now the economy is great, if in 3mo you are back on the job market saying "I'm an awesome PM and I did a coding bootcamp to increase my understanding of the products I manage so I can be an even better collaborator" you will just have increased your value significantly. Probably you could just go back to your old job with a promotion.
Looks like an interesting idea, but I have a suggestion.

I'm not a CS'ist, nor even a professional developer, but I know that CS pays a lot of attention to methods for how to write good code that can be reviewed and maintained. And I make an effort to study and apply those methods myself.

I wonder if it would be an interesting line of research in CS, and within this training, to think about how some of those methodologies can be applied to the lowly spreadsheet which, for so many people, is their main if not only programming tool.
This is an excellent article. It opens up the minds of people who many on the coasts have struggled to empathize with in light of Tuesday.

In talking about economic policies, and free trade deals that supposedly shipped jobs off to China, I wish the article (and more importantly politicans) would emphasize the importance of technology being the driver behind manufacturing job loss.

It's only a matter of time before robots replace most manufacturing jobs. The only reason they haven't full-scale yet is that wages in China are still too low to make it cost effective (but that's changing).

Otto just delivered the first self-driving truck shipment. In a few short years, the most common job in what was it, 30 or so states? It'll be all but gone.

The article hit the nail on the head with having working class economic policy being front and center on the campaign, not bathrooms. But a tariff on Chinese exports ain't it. Nobody is bringing steel back to Youngstown, and though Clinton touched on this a little bit (the renewable energy jobs for example), creating new jobs that are actually here to stay for a while -- whatever they may be (while unfortunately not seeming elite and professional) -- is the only message the Democrats can deliver if they want to win office again.

Building better government, Seneca Systems (S16) is hiring
I'm partway through the ML class on Coursera and have only recently rekindled my interest in Math. However, my background is in Accounting (undergrad and did a full years as an accountant), and Software Engineering (masters in SE and full time now for some years). Is there a path to actually move into a Quant Job given a software background, to someone who's mathematically inclined? My fear is that I load up on extra "free" math classes, teach myself through MOOC's and self study, and won't have the required degree or connections to break into the field. Is there a recommended path (or is it even possible) to make the major switch from Web Dev to Quant?
The domain move which protonmail did looks quite risky: Country TLD to generic domain, new domain parked at Godaddy before and the first owner of this domain run an email server which maybe did unexpectedly closed shop. The domain move happened at the same time when protonmail vanished from the search results.

Instead of publicly looking for a scapegoat for their mistake they should tell readers of their blog the one lesson to be learned from this story: Never use a country TLD for something targeting more then this country!

Except, some of that regulation is important. If you're in a hotel, and there's a fire, you know to follow the signs out. There are exit signs, emergency lights, and maps showing you where to go. In someone's house, they don't have any of that, which isn't an issue for the person living there, because of course they know how to get out of their own house. But when it's being rented out, there are certain regulations to make sure that someone unfamiliar with a building can still exit in a fire.

Driving up rent is something that's probably unavoidable, but safety is something AirBNB could try to enforce if they wanted to.
