Ask HN: What's a better way to digest regular/tech news?
You can read HN/reddit/others and see news others think is good. There are many services and apps like Flipboard which try and find the best news for you. Then we can just stick to one or a few news sources and go with that or possibly use RSS where you just become so overwhelmed you stop reading it.

Sometimes I see stuff on facebook news that I don't see on reddit. HN is mostly tech. Apps like Flipboard and Smartnews, while nice tend to gravitate to buzzfeed and businessinsider articles. Google and Yahoo news aren't much different. In fact the google news android app can leave you in the dark on some events and you wouldn't even know it. RSS is just too much to keep up with. Specific news sources like the NYT tend to be too broad.

There's an app named Flipboard Briefing which is actually decent but regular Flipboard just has too much content. Briefing has too little.

Is there a better way? There must be. I should say I am mostly interested in big events and tech news.
Henry Ford wasn't a founder of Exxon.

That would have been some trick, given that Exxon didn't exist until 25 years after Ford died. ;)
Going along with the metaphor of the submission: sure, in the same way you can plant a solar cell on your roof and get "free energy" from the light pollution during the night if you live in a city.

Or, literally, the energy is way too low to benefit from it. Sure, the TV might blanket space with a few watts of interference, but going by the law of quadratic decay that's not worth much at distance.

All this noise does is prevent observation of low-energy signals. It does not contribute to a high-energy signal itself. (Goes for both light pollution and RF noise.)

Edit: unless, of course, you mean we can "harvest" this free energy by making our appliances conform to regulations, in which case it's an obvious yes.
It would seem to me that the ones blocking nuclear power are a small subset of those concerned with humanity-induced climate change.
European countries used food stamps during WW2. It implies that country does not have enough food, if it has to ration its food supplies. I know it is social assistance, but it has really bad name.

NHS is paid health insurance, sometimes pretty expensive, not much relevant.
Tesla Linux, of course. Duh.
Google Nexus EOL
Yep, it's that easy.
My two main arguments against nuclear:
1. Have we solved the waste problem satisfactorily yet? This includes accounting for war, tectonic movements, water safety and a host of other factors.
2. Are fines and punishment for not building nuclear facilities high enough as to be effective in enforcing regulations?

Iff those two are satisfied, go nuclear. Before, nope.

But even if they are satisfied: nuclear is a stopgap. Solar and wind are solutions. So I emotionally welcome everything which pushes those forward
If you think that just because all their editors are on CIA payroll, I think you have to much faith in CIA security.
"With nuclear incidents people are persistently reminded whether through apocalyptic movies or people going into the exclusion zones to photograph the ruins that are left behind."

We could make movies about dams that collapse, too and we have. I'm not even sure there are more about nuclear accidents (nuclear war, yes, but accidents?). Even if there are, I think the movies are a symptom of the problem, not its cause. The invisible danger of radiation being held back by walls of concrete just looks more dangerous to us than the visible danger of a wall of water being held back by walls of concrete.

And Chernobyl? A nature reserve. I can see someone writing a SF story about cultures that protect existing nature by the controlled disposal of radio-active material.
TV detector vans, despite being theoretically possible to build, are a myth and just propaganda spread by the TV license collection agency. At most they drove around in vans with some random gear in it as PR stunt.
There will be naysayers when a second or third world country achieves a milestone. Inspite of similar feats done before by developed nations, this is huge for developing economies. Similar thing happened when the earlier Prime Minister of India announced that India will launch a Mars mission within a year at a fraction of cost at what NASA or ESA would do it.
Most people laughed at it, and said it's impossible and what not. But guess what, India did send a successful Mars mission that's orbiting the red planet right now. Since then I take 'Expert' HN comments with a pinch of salt. Sometimes HN acknowledges a feat only when done by Elon Musk, NASA or ESA.

Yes you could probably mine our dumps for metals, but if England is anything to go you will run out of forests as an energy source very early in an industrial revolution. If England had not been sitting on a large amount of easily accessed coal we would almost certainly not be having this conversation - in English anyway.
Frankly, no; I've used all of Postgres, MySQL, MSSQL, and SQLite, and MySQL is the worst of the lot. No, PostgreSQL isn't a holy grain, but any user of MySQL would overall be better served by PostgreSQL; especially on AWS where the replication is so simple to set up, which IMO is the only good argument I've heard in favor of MySQL (but I hear even that is fraught with peril).

MySQL is so completely riddled with bugs and utterly baffling behavior — it is the PHP of relational DBs. What I remember off the top of my head includes attempting to subtract datetimes causing the punctuation to be removed from the datetimes and the resulting "integers" to be subtracted, FK integrity being violated in a number of easy-to-hit corner cases, the "utf8" encoding not being able to encode UTF-8 (and the default being latin1…), GROUP BY allowing obviously (i.e., catchable to the parser) broken queries, `SELECT * FROM table` on <10k row tables taking minutes in some cases, the SQL dialect swapping the words "key" and "index" inappropriately; Read [1] if you want more.

Thus far the only other tool I've seen come close to this level of insanity is MongoDB. The thing about a tool so willfully discards any sort of reasoned approach to its topic area is that the people who use it — who inevitably are not well versed in how a relational database works "in theory" — cannot derive from its behavior its rules, because its behavior is irrational, bordering on psychotic, and the people using it tweak query after query while having no understanding of why one query might work better until some abomination that someone usually works is crafted; `-- Don't touch`. A good tool — I believe, somewhere deep inside me — will teach the novice user. MySQL will not; it will drive you insane.

When did you try 23? It recently also got kernel 4.5, so there might be no differences.
A small subset? They've effectively won the policy debate. Nuclear is either banned or being phased out in most of the West.
The crypto involved in U2F is extremely hard to do in an AVR. There are issues with sources of randomness (I'm currently playing with implementing entropy via Watchdog Timer jitter on the ATTiny85, which appears suitably random but is slow), and the capabilities of the devices themselves to produce output at reasonable speeds.

A slower Cortex M0 might not be sufficient to get decent speeds, but I suspect an M3, something like an AT91 could do the job.

I'm curious about the following statement in the README:

> The token is durable enough to survive on a key chain for years, even after going through the wash.

On the other hand, the token is shown as "naked electronics", without a husk.

Is that really sufficient for such a device? Does it really withstand (mineral) water, mechanical stress (key chain), let alone the combination of both (washing)?

> Because I'm human and can't maintain 30+ passwords?

The original question was about GoToMyPC providing more details so someone could "estimate the risk".

If you're already reusing passwords, that becomes rather easy: Your risk is dominated by the fact that you reuse passwords across services. No amount of details from GoToMyPC is going to affect that very much--whether you even used their service or not.

Seriously, just start using a password manager. It's not that much effort, even just for the peace of mind that you're finally setting passwords with the desired strength that you already know is necessary, but couldn't afford to maintain / memorize.

The hardest part for me was trying to decide which one to use :) I settled on KeePassX, because it's free and open source, has an Android app, doesn't store your stuff on their servers (just one encrypted database-file you can safely keep synced between devices via whatever method/cloud storage you prefer). I've been keeping an eye on the pro's and cons between various password manager options, and as far as I've seen the biggest downside to KeepassX was that one security researcher didn't like the user interface (it's fine, IMO) whereas the others either keep your stuff on a server somewhere, are not open source, or both.
I would recommend Chapter 8 of `Common Lisp: A Gentle Introduction` by David T. [1]

It is the most lucid explanation of recursion using the story-telling format.

After working through this chapter, I have never failed to write/understand programs using recursion.

Can teenagers survive without social media?
Well when your top engineers get paid 25k sure you can do it for a fraction of the cost. Why couldn't you. Indian military already has tons of tech that if they bring to the civil sector they could use to compete with whatever. The problem is usually corruption and funding. The intelligence is there, in a billion people there are a few million outliers.

Heck most of American Fortune 500's are leveraging Indian brains to increase profits. Google is run by an Indian and so is Microsoft. There are Vikram Musks that are already captains of industry in America. Born and raised in India.

India is a country of disparity. Both intellectual and economic. That problem is not going to be solved any time soon. But if Indians want to create companies to compete on the global stage there is not much stopping them other than their own government and financial systems.
That's certainly an improvement from 20-30 cents/kWh.

However for solar PV with storage to replace natural gas their combined cost is going to need to be less than 6 cents/kWh.

The combined cost of solar PV and storage is currently 20-50 cents/kWh.

Do you really see a 10x performance/cost improvement right around the corner?
Yes, I think I mention that in the lesson. You have a trade off.

1. Instantiate the dict each time, make the code super readable and the choices right next to where they are used.

2. Make the code efficient, move the dict to a static / instance level variable away from the use case at the cost of clarity and maintainability.

My slide chose clarity and I would recommend you write clear code over fast code until you profile it and see it's too slow.

That was my motivation for the slide and demo.
>> the typical indian isn't any more healthier than say the typical american if we're just looking at diet alone.

but is eating tasty non-meat food that is lot less destructive to the environment.

that cuts to the meat of the argument against non meat( which in the West means fake meat or vegan foods) being non tasty..
For static pages that is kind of irrelevant though.
I'd flip this argument around. Have we adequately solved energy storage and base power load problems with renewables yet? That is, can they feasibly serve as a primary power source or do renewables have to be coupled with sources like goal and gas?

If that's the case, sure, go full-tilt renewables. If not, then we have to weigh nuclear waste is a bigger problem than contributing to CO2 levels. I'm inclined to say no -- if only because nuclear waste can be a reasonably localized problem, whereas climate change from CO2 is global.

AFAIK PayPal only do this if they have internal proof that laws are already being broken on the according websites. I don't know Seafile, but the same happened to other file hosters in the past which silently and willingly accepted that copyrighted material is exchanged by using their services.
Unless there are people in the "crowd" who work in machine learning / data mining in totally different sector (let's say genomics/biostatistics as this is the example in the article) but have no access to the hedge fund world.

The "crowd" could very well have a long list of very intelligent people who are "experts" in some other sector and who have fresh insights and want to get some anonymous extra income on top of their salary.

This said, I think their compensation seems really low.
The Growing Risk of a War in Space
Which means they could have put out twice the clean energy in ten years time if they didn't have to shut down the nuclear plant.
There is nothing wrong with the idea per se. It's just implemented badly in Python. Instead of allowing unlimited abstraction, which is the only way to unlock this desired simplicity on all possible levels, they're limiting the abstraction and therefore increasing the complexity needlessly.
> And yet, PG&E has said they'll be able to replace the displaced generation with renewables, energy efficiency, and battery storage.

And I'm sure that's exactly what the regulators and the politicians controlling the regulators want to hear. Smart business sense, given the political climate in a state that sees its insurance commissioner trying to strongarm insurance companies doing business in the state into not owning anything related to coal.

PayPal Dumped Cloud Company After It Refused to Monitor Customers' Files
Thanks for writing this up, I'm just at the tail end of having re-architected the CloudFlare billing system, also a subscription system written in Java with a MySQL back-end, but fronted by a Go API that insulates the rest of the business from the internals of the billing system.

The blog post covers a lot of the high level stuff really well, but I'm interested to learn whether you experienced any issues along the way, what they were, how you dealt with them.

In CloudFlare's case our migration was made more complex by also adding PayPal, and changing our processing gateway. Both of which created risk that we've had to work hard to understand and mitigate, i.e. how different gateways may, with the same card, return different results, etc.
Big Data Analytics – Overcoming Its Gestational Hiccups
OK, I presumed that wikipedia article would be better. Anyway, there's dissenting opinions within the NRC that disagree with PG&E and allegations that the safety reports were done poorly.

Under renewed scrutiny, PG&E is due to release ground-shaking safety reports in 2017 for the renewal of its lease in 2024 after some newish (last 7 year) USGS surveys suggested there may be more threats and that the fault lines may have not been properly characterized.

Also there was a whistleblower case against PG&E in the early 2000s claiming that safety concerns were routinely minimized (think deep water horizon) and expressing great concern for the accuracy of the claims of safety. (http://www.greenspun.com/bboard/q-and-a-fetch-msg.tcl?msg_id...)

Anyway, there's serious safety concerns regarding this particular plant and that it could be the US Fukushima given its location and the fault line proximity.
it is not. Atleast as per this UK study[1]

Yeah, sure, hire a Ruby/Python programmer ... and try to trick them about the language they're going to be using by being vague about it in the job posting and initial conversations until they got really interested?

Been there, done that. It was a stopgap measure that sort of worked and it wasn't that much fun.
I wonder if functions, or their equivalent, is what makes programming complicated for many. Because now you have one set of code that crops up in multiple places, and have different states depending on how it gets used in those locations.

The reason people reach for spreadsheets seems to be because they are visual. much like the register panel "blinkenlights" on early computers, spreadsheets allows someone to glance across and check the state of things.

And in an earlier discussion about this, someone pointed me to Apple's Numbers spreadsheet. There you can have multiple freely moveable and expandable sheets on screen at the same time, each addressable via its own name.
I am living in southern Germany, about 1000km west of Chernobyl. It is not safe to eat mushrooms from the local forests and every wild animal shot has to be scanned for radioactivity before being allowed to be eaten (and often enough they have to be destroyed). This is not going to change in my lifetime and beyond.

As a physicist, I am certainly not afraid of "nuclear" and "radiation" in the abstract. But seeing the country you live in to be contaminated for so long just because a single operator error is quite sobering. Solar has its challenges on the technical level, as the power output depends on the daytime and weather, but that is not killing anyone. "And who say that batteries can't explode?" - well even if they would, you would have a ruined battery, perhaps a building. That can be rebuild. The damage done by Chernobyl cannot be fixed for centuries.

The good news in all of this is: by now solar has become cheaper than building new, safe and modern nuclear reactors. And as a lot of the grid load in California comes from air conditioning, I fail to see how solar would not be the perfect solution for these kind of loads.

1. It's out-of-the-ordinary. Nobody would pay attention to the monthly news report that coal burning has, yet again, damaged the environment to the same degree as a meltdown.

2. Our monkey brains are incredibly bad at realizing that gases can be more dangerous than those scary barrels with scary warning symbols. Instead of being hidden away underground, gasses conveniently "disappear" into the air.

> 1. Have we solved the waste problem satisfactorily yet?

Technically speaking? Yes, for sure.
Politically speaking? Hahahahahahahaha no, nowhere close.
Yes, which raises one possible way of fighting it: Make electronics manufacturers adhere to power efficiency ratings. The moment they have to care about how power efficient their gear is, they'll look at everywhere power's being wasted by, I don't know, being broadcast into the air for absolutely no good reason.
Quant fund insider here.

The data is pretty pure, in the sense of not telling you any metadata at all. It's literally just a bunch of numbers and 0/1 labels.

It's hard to implement a strategy without knowing what exactly you're looking at. I get the feeling this "pure dataset" is part of some framework that Numerai thinks will beat the market, given good predictors.

That's not necessarily the case. Say I assume the 0/1 means up/down over some period. Well, being able to guess 0/1 correctly would obviously help. Say I'm right 70% of the time, then I can equal weight my bets and it will be just swell. But say I'm right about 51% of the time. Then it's going to take quite a while longer for the law of large numbers to work in my favour. Remember your ML algo will only be able to give you good predictions if some of the 21 features are actually meaningful, and we have no reason to think they are actually meaningful.

Now, let's say I have some domain knowledge in finance. I want to predict over/underachievement relatively. I would be able to guess which shares go up relative to others, but not the market factor. That would require a different framework to the one I'm supposing is presented here. Is there flexibility for that?

The secrecy thing makes me wonder, too. If it's just a matter of not showing your work, why don't you just have a website where people submit their daily/weekly/monthly portfolios and you keep track of the tally?
