Ask HN: Expert Connect for school students?
Hi, we are a new startup helping school students in choosing their field, tell them about your field and how you got there so that when they choose a career it's an informed decision. We are looking for enthusiastic people to come on board as experts, get in touch if you'd like to help(based in New Delhi, India) goo.gl/T6RLmR

We are planning to host workshops in schools for student expert sessions. The problem is when getting out of school most students have no idea how to choose and what to do? Some sure have some idea but most of them are lost and choose engineering and figure it out later we want them to take this decision in an informed way.
After a month of trying out things, I mostly use Echo as a voice controlled music player - kids love it for that too. so this is more a Dash competitor than an Echo competitor.
Yahoo Cuts $4.8B Deal to Sell Core Business to Verizon
> If you, or anyone else can be more rational, and predict the market's errors

You can't rationally predict irrational errors. At best you could have spotted the trend early and jumped off at the right time, but that is still speculating on the degree of irrationality.
Jeff, I've used a recent RetroPie (v3.3 afaik) and Pi2, which is only slightly slower that Pi3. I've also attempted to overclock it - it helped a bit, but not much.
I've never purchased anything using my Echo, but find it invaluable as a home assistant for all the things it does besides shopping. Shopping via text interface, if we're still at the stage of "personalized to your tastes" being a laughable claim, is a terrible experience.

Q- why does this Alfie device exist at all? It appears to just be a button + microphone that starts a chat session on your phone. There's no point in making that exclusive to the device. If you can't already, I'd be amazed if in a year you can't do this through the Kenmore app/website.
Perhaps the above should have said "then don't make such a claim" instead.
Thank you for the thoughtful comment. I believe I read that John D. bought up smaller companies because he was obsessed with the extractive commodity boom-bust cycle. His intention was to raise prices.

I'm really interested in this comment: "oil prices are set low by the market" Do you mean when externalities are included?

Re: consortia, and cabals - restricting output and raising prices will bring new entrants into the market. Eventually the cartel loses control.
With HTTPS you are protected against this, the EFF is saying, that a "full protection is only a VPN or Tor", because you have no control over whether the website offers HTTPS or not.

In each of these cases the traffic is encrypted, Verizon can read only gibberish and cannot know where to insert its tracking code, while with HTTP it sees exactly where the HTTP headers end and can add another to them.
More tech hubs. I'll admit that I don't know enough about housing, but the bay area and Manhattan are both water-restricted in terms of room for housing development and DC has political restrictions on land developmentment as well.
Anecdata?
Can you show an example of "lowest common denominator" being misused? I've never noticed it so fear I may be guilty of misusing it.
I'd argue purist gamers aren't emulating at all. The super accurate emulators really target a very small audience. If you're really into old games, then nothing can replace the actual hardware. And nowadays you can easily use an SD based flash cart to get the main plus of emulation: download any game you want off the internet.
I find the `Printer + Scanner ~= Copier` example poorly designed.

Sure, the Copier has both Printer and Scanner, however, in practice, the "Start" function on a Copier differ from either -- it starts the scanner and forwards it to the printer. It might also print multiple copies.

Point being, the `start` functionality here differ from both Printer and Scanner hence, the `start` method shouldn't be inherited.
Haskell has something even cooler. Automatic program synthesis through examples: http://nautilus.cs.miyazaki-u.ac.jp/~skata/MagicHaskeller.ht...

For example:

f "hi" == "HI"

Gives:

f = (map toUpper)
First thing I thought was: let's download that and make a game out of it; maybe use location data to start of easy with birds from the region, but I'm afraid it can't be used for commercial purposes (all mobile apps are classified as such by their documentation) without acquiring a license (which is understandable, but regrettable at the same time).;
I think Sivers can make the distinction between commenting on some draft wirh feedback welcome and a demo of some feature about to be released.
How much latency does one of these add? It might be fine on a modern cinematic console shooter, but a large amount of the appeal of some old arcade games is their frame-perfect timing. I can't imagine that's helped by adding a round trip over the network, not to mention streaming the video back. That's gotta add 2-3 frames' latency at the very least.
India's reverse Brexit: Passing the GST Bill will create formal sector jobs
Retail stores don't pay their employees either, if you count the people who manufacture the actual goods. Nor do they pay the truckers who actually get the goods to the store.

They pay janitorial staff and retail assistants. I guess a metric shit-ton.

Yes, it's an imperfect metaphor, but it's showing that you can still provide value without being the origin of the object.
I personally prefer video courses, like those on Udemy:

Something a very smart person advised me was to "Tell people what you want, not what to do"

It sounds so simple yet is surprisingly hard to practice. It really puts the onus on you to think carefully about outcomes you desire and explain it clearly.
> bought all those robotics companies and ran them into the ground

Did this actually happen? I know there have been cultural issues with Boston Dynamics, but the other acquisitions seem to have gone fine. Folks from Redwood, Meka, Bot & Dolly, and Holomni are still working at Google and many of the founders are director-level in the robotics groups.
Copypasta's are not usually appreciated on this website, in my experience.
Funny choice of exmple, the algorithms I am aware of for finding shortest paths require mutable vertices that store the scores and pointers (edges) for the best part found so far.

No doubt there ways to do it in a pure functional language -- but that requires a bit of thought. Compared to that difficulty, this business of return values seems trivial.

Worse, a language that forces people to Do The Right thing, might be acceptable for experienced programmers who want to work within that limitation. But when given to student, it just encourages closed minded rule-following.
Amazon is a much better example of a moonshot than Google search. The key idea is easy to state: an easy-to-use online store for almost anything, with fast and cheap delivery. But how on earth do you make that work in practice? You need a ton of business deals with various manufacturers and brands, you need warehouses everywhere, you need a massive delivery network... the investment required is just staggering. And indeed, for many years they were criticised for not making a profit, but the investment is clearly paying off.
Exactly. If this article annoys you, read it again carefully, it does _not_ argue against feedback in general.
Was it in trouble before?
I think your subtle focus on the semantics of the reply highlight a common block to agile feedback loops, small batches and generally getting things done. Sorry if that's harsh but you either missed the point of the article entirely or just overlooked it, the latter possibly being worse.

The primary point IMO is "don't squash ownership" because the cost of doing so is often not fully realised.
The secondary point is "don't sweat the details". You've kinda proven you don't get this yet.
I like the way Joel Spolsky describes managers taking this even further at Microsoft back in the day.

They wanted to make sure the engineers knew that they were the ones designing the software, to the point where they would refuse to even step in and resolve a conflict between two engineers about the design. Even when those two engineers came up and asked for help resolving said conflict.

Now you've got three people in the room: a designer, a developer, and a manager. Who's the person who knows least about the problem?

Solve it yourself, guys. Perfect.

If you can't predict them except in hindsight, well then how can you say it's irrational? If you can't tell me whether or not investing in Nintendo stocks has negative expected value, you shouldn't call people doing it irrational.
The correct version is greatest common denominator. The lowest common denominator is usually 1.
Amazon Picking Challenge
I assume GP was refering to the "great work" part, but even then it's just matter of style; the point was only to show approval without nitpicking, not emphatic congratulations.
As an independent contributor I don't want my manager weighing in on my choices. I see them as out of the loop on the more technical aspects of my job and they should leave those decisions to me.

If I come to a more technically senior member of the team who is more knowledgeable, it is to _precisely_ ask for their opinion.

So in my mind: if you're a manager, don't bother; if you're a more senior IC, do, with the explanation of why your approach is better. You're more of a mentor at that point than a manager.

Oh, and if your approach isn't really better, just different, keep it to yourself.
So everyone understands that the short term downloads/revenue would NOT justify the crazy increase in market cap of Nintendo so far.

However, what distressed investor is not the fact that Nintendo didn't adjust quarterly earnings, but the conservative management team refused to signal that they acknowledge the potential of their IP + mobile + new technology such as AR and change their future strategy to be beyond in-house consoles + first party games.

It almost seems to me that their management is embarrassed by the meteoric success of Pokemon Go, considering that they have traditionally been very reluctant of creating contents for smartphones. Now despite their pride, the biggest value jump in their company's history was not lead by any in-house product, but literally a 3rd party American startup writing an app on a platform they traditionally ignored.

I wouldn't be surprised if they are trying to downplay the impact of Pokemon Go just to save face.

Investors, on the other hand, just want to see them acknowledge this potential gold mine and commit a strategy in the future.
Let someone who is pedantic about language, be pedantic. It's not like this is a feature unique to the reddit user base, it abounds on all corners of the internet.
Can't upvote this enough.
So, since the authors are here, I have a couple questions.

How is this correlated with legalization? From an intuitive standpoint, it seems like someone who thinks they have "less to lose" would try illegal drugs which carry risk of incarceration, and that same kind of person might consider suicide.

To me, the fact that the effects happen in reverse order (whether suicidal ideation precedes cannabis use or vice versa) indicates that there could be some kind of common cause for the two effects, and that it just manifests differently for men and women. Unfortunately the full paper is paywalled.

Moreover, this 5th annual anniversary of packersmoverspunerates.in was successful and very effective in terms of business development idea development.
Ah yes, it's too easy to think that a comment is addressing one point when it is addressing another.
You can view a programming language like a fighting weapon ( although I don't promote violence ). If the enemy is right in front of you, you may kill it easier with a sword then with a nunchaku. But if he is around the corner, you may have better chances with the nunchaku. Or if he's at a distance you may use shuriken. One weapon can't offer all benefits, because it becomes impractical or dangerous.

The reason why an OOP language doesn't let you have functions outside a class, may be the same with why you don't have blades on a nunchaku. You may hurt yourself.

One needs to understand the strenghts and weaknesess of each weapon, and when it's better to use it.
They practically operate their own business incubator.
> but my next upgrade will probably be a separate router and WiFi AP

Personally I go the "other" way. Router + WiFi (I use an Airport, but pick your poison), and then the most basic modem possible for the location - this might be a provider-supplied DOCSIS Modem/Router in bridge mode, right now it's a provider-supplied "1 port" ADSL2+ modem/router in bridge mode. With an ADSL setup, you'll probably need to use PPPoE from the router, with a DOCSIS setup, the auth is usually on the MAC address so your router doesn't need to know anything, it just connects via IP to the bridged cable modem.

If the modem ever gives me issues, I'll just replace it with a plain-jane ADSL2+ modem. If the ISP's expand their docsis/fibre network past our new house, I'll just swap the ADSL modem for a DOCSIS modem/router in bridge mode.

This setup has given me the least headaches in every scenario across several houses in both Australia and Thailand. The only hard part really has been trying to express "I want a DOCSIS router that i can turn off the router" in a way that a Thai-speaking technician or my non-technical english&thai speaking wife can all understand.
Illegality is indeed one of the possible mediators of the association. A recent study has demonstrated decreased suicidality in states where cannabis was legalized
The very interesting thing is the degree of denial - of ANY negative side effect -- of using pot among any user. The vast majority of smokers would laugh it off if they were told "there's a notable correlation between suicide and pot use."

I smoked it for about 3 years as a teen, between 1976 and 1978. In those days about zero 'horticultural engineering' was done to the stuff -- the potency was low.

But the effects were dramatic. And negative.

Now? The stuff out there now simply MUST be highly 'engineered' after 40 years of time from when I used it recreationally. The odor is so overwhelming, so strong. The 'skunk' odor.

Back in my day the stuff consisted of stems, leaves, and a bud here and there. The buds had seeds. The seeds would sometimes explode like popcorn. All the pictures of the stuff I see nowadays -- it looks like all buds, and seedless.

In the 1970s, what made me stop it was this. Recall that if you're riding a bike on the right side of the road, cars pass by. Okay, imagine a huge truck passing you and suddenly it swerves to the right -- the huge truck almost hits you but you escape being hit/run over by steering your bike into a ditch.

You are quite shaken, lots of anxiety.

It's NORMAL to feel anxiety at a time like that.

The "I'm in trouble" indicator is -- feeling anxiety for no such reason. No imminent threat, no "I'm late for my final exam", etc. Just smoking the stuff and then feeling anxiety.

You know you're in trouble with that stuff when you cannot seem to shake off the anxiety.

Contrary to what 99.99% of pot users say, the drug -- like most drugs -- HAS SIDE EFFECTS.

I stopped because I felt anxiety and could not shake it.

Stopping the recreational use solved that problem.

Suicidal tendencies from pot use? I had friends back then going to psyche wards and rehab to try getting off that stuff. In the 1970s. When it was FAR LESS potent than today. I don't know if any of my friends/acquaintances back then ever got low enough to off themselves.

I never argue with anyone these days when they discuss how 'wonderful' pot is. My only wish would be -- remember, it's a drug and drugs have side effects.

You'll know you're in trouble when you have anxiety for no reason -- other than the pot use -- and you cannot shake it.
The share price exploded from a single free game because it became a social phenomenon.

There wasn't any sort of serious financial analysis going on, just hype.
It was so big not many people wanted to review it properly. There weren't many steps of implementation (essentially a single-patch dump) and it had some high level features which don't necessarily belong to the kernel. Developers of kdbus also brought up performance gains a few times, even though it's been pointed out the userland is not the problem. It was the actual implementation that was bad.

It's being reworked into bus1 which is a slim, generic bus implementation. Full dbus can be implemented over it, but it's not forced on people who just want a nice, light bus interface with some security guarantees.
Apparently a lot of people thought this: http://www.theverge.com/2016/7/25/12269466/nintendo-stock-pl...
Eh, it should be highlighted that the Google Authenticator app on the Play Store is NOT the one on GitHub, which is a much older version. The current version is closed source, and cannot be assumed to keep working if a Google account is banned.

(I strongly recommend people compile and switch back to the old open source version.)
What you describe as 'more pressing issues' can be defined as stressors and it's a person's defense mechanisms or active coping skills for dealing with them that determine their success in life. It's why kids are on psychotropic medicines and can be triggered as adult-aged college students. Teaching people how to actively deal with reality in a healthy productive manner is what we need in common core.
This comment doesn't make sense. Parent is commenting that it's _not_ a law enforcement issue since writing is generally protected speech.
One point I see unaddressed are efficiency gains. Couldn't we increase efficiency and effectively make that finite supply infinite?
I think the issue I have is that the author is taking an all or nothing approach. Either something is all wrong and a larger discussion must be had or nothing is worth noting. There is a huge range of things in between there, many of which may be small opinions.

After reading the article a few more times and the comments here, I'm getting the impression the author meant "don't add pointless opinions or suggestions to things." The use of the phrase "my two cents" beguiles the author's intent, as in many cases that phrase is not used when one has a pointless opinion.
Thanks, sounds like it's just what I need!
And http://ioccc.org/2015/yang/spoiler.html contains a Javascript-based replay of the author writing the program. From an empty editor window to non-obfuscated code to the ASCII art face.
Even more dangerous if your attention is on the phone mounted on the handlebars running Pokemon, as I saw on the weekend.
There are a serious amount of people users, many from a new audience. It is the first breakthrough "Augmented Reality" application, paving the way for a new type of game that everyone can enjoy.

How can you definitively say it is hype or not?
You're better off funding research and startups directly. We need more DARPA and similar research investment funds.
The problem I've found is that a few of the ISP supplied devices no longer allow bridge mode, or you lose access to features ("free" city wifi).
Why only for a few weeks?
That's the big thing that stuns me every time Google does this. For people dependent on their services, Google is effectively giving them an online death sentence. Without access to your email, you may have a lot of difficulty regaining control of accounts of yours all over the Internet as well, depending on their email change policies. If you've been using Gmail for as long as a lot of us have, ten years of your online correspondence is just... gone. And if there was a clear avenue of appeal or communication, this wouldn't even be so bad, but when Google gets rid of you, they won't even give you a chance to talk to them about why they did.
Yup what a stupid, stupid, company. If only they had the wisdom of Silicon Valley Startups. Then they would be a real company and be able to create innovative and disruptive products that changed the world! \s
> Cares and knows about DNC and specific candidates. Guessing they are following the election process, so probably live in US or Canada.

For this you underestimate the global interest in the US elections. It is so influential on the rest of world many take keen interest. This can easily be lunch-break talk in Australia. Not sure about the other points.
Ask HN: Blockbain-based, global distribution system for space (big) data
Hi all,

I'm starting a large, multi-disciplinary project (as part of ISU SSP16 [1]) to develop an architecture for a global distribution system for big data from space. Currently, most remote-sensing data, astronomical data, etc. is stored in data silos around the world. A lot of the data remains unprocessed unfortunately.

With the wealth of data being downlinked from space every day, there's a pressing need for a new, global system for acquisition, storage, processing and distribution. We're aiming to develop a system that is replicated, resilient (i.e., no single points of failure) and verified.

One of the ideas we want to explore is using the blockchain to distribute data globally; an idea that others seem to be looking into [2]. It's quite an attractive prospect to have a fully decentralized system that is independent of any centralized clearinghouse for data distribution. The main objections for space data seem to be related to privacy and national security. The data is also highly varied/unstructured.

Since my knowledge of blockchain technology is limited to a cursory overview, I was wondering if the HN community could help me get insight into the following questions:

1. What are potential technology limitations that would restrict use of the blockchain for management and distribution of big data?

2. Since I assume that the data can't be stored directly in the blockchain, is there a way to store the data reliably elsewhere and utilize the blockchain for decentralized registration/lookup?

And finally, as part of our survey:

3. What would you use space data for?

Thanks in advance!

Part of that may be Japanese culture; part of that may simply be Nintendo not caring. They do what they want and most of the time they do an excellent job. Their games are so good that too many mobile games might serve more to dilute their brands than to make them long-term profit.
