I think operating temperature is important, so I'd imagine outside or garage is a no go? (My garage gets down to 40F at night, not sure if that's typical).

But maybe with enough insulation you could put it anywhere?
Interesting tidbit: the barrier to legally registering a custom automobile in the US appears to be pretty low: http://www.dmv.org/other-types-of-vehicles.php

The ones I browsed call out a safety inspection, which is probably the highest hurdle to jump. I strongly suspect this is just basic safety, e.g. turn signals and brakes work.
Ask HN: First tech talk I give, any tips?
I am giving my first tech talk with Frontenders Valencia ( http://valencia.frontenders.me/ ) about a project that I made and debuted here in HN, Picnic CSS ( http://picnicss.com/ ).

Mainly, I'm really nervous and insecure right now and would love to boost my confidence. HN looks like the proper place for me to ask: any tips? I know to:

1. Review, review, review the presentation
2. Arrive early to get to know the people

“NoSQL injection” – what 40000 unsecured MongoDB databases mean for our industry
I have a friend from high school who, at 40 years old, had an amicable divorce with his wife so he could go do something similar to Christopher's adventure, but here in the backwoods of Georgia. His philosophy is that we're all going to die sometime, so we should live the life we always wanted to live on this "ball of dirt and water hurtling around a ball of fire" as he puts it. I envy him, as I'm also an avid outdoorsman who never gets to go outdoors anymore (from the house to the car to work and back does not count as "outdoors"). My friend studied flora and fauna for years, both because he loves nature and in preparation for the rest of his life on his own.

So far he's been out there for the better part of a year, sleeping in a bivy sack, eating what nature provides, riding his mountain bike and towing his trailer with his few worldly possessions, a backwoods hobo by choice. He's documenting the entire adventure and plans to write about it. He is fully aware of successful adventurers before him, as well as those who died to soon like McCandless. Who knows how long he'll live this life, but he looks to McCandless as an inspiration, not a "clueless kid", and he's doing just fine.
I said "it sounds...", not that it was from a throwaway account. The "nasty" bugs you referred were never a problem for me, and the way you wrote sounded sensationalist.
Amen. One of the best things a college career counselor can do is make sure kids know they aren’t special little snowflakes, or super rock-star A+++ awesome. It should not be a shock that an entry-level position is doing entry-level work.
Yeah, this sounds more like CrunchPad-level PR. Someone without experience making a car is going to make one. Notable because of the country only.

There are not a lot of roads in Sri Lanka where you can drive that kind of car, either. But electric car range is perfect for the country — you can drive from the west coast to the east on one charge.

Five Reasons Not to Vaccinate Your Child
One of the biggest issues is that a FPGA design running at 50-100 MHz (compare to the contemporaneous Cray-1 80MHz), with little memory that can be used as cache, gets blown out of the water by a +3GHz CPU with megabytes of on die cache. In terms of just being a "Lisp Machine", it only makes sense as retro-computing. Even a CADR, 3600 etc. simulator running on a fast x86-64 CPU would be (a lot) faster.

> Immutability has benefits in terms of correctness, but not in terms of scalability to more processors or total throughput.

Wrong. Immutability can (and often does) increase scalability. It does that mainly by making this situation harmless:

> With modern memory hierarchies a lot revolves around never letting two threads touch the same cache line and this happens at all you lose at least an order of magnitude in performance.

I specifically referred to C++11. And I believe your example with the T{val} is C++14 so I don't know much about it.

My experience is working on video game engines with other people. As a senior developer a large part of my job is jumping through a wide range of systems written by other people to debug problems, identify ways to increase performance, add features, etc. There's also a lot of code written by people who have moved on to other jobs.

We've had quite a bit of code that was full of autos. In my experience thus far auto has never made code more significantly readable or easier to understand than not using auto. (excluding iterators/lambdas) Not only has auto not made code easier to comprehend the use of auto has made it significantly more difficult to understand on more than a few contexts. If deducing a type as a human reader of text requires backtracing a half dozen calls of code across who knows how many lines of code, and even files, then I'm gonna be justifiably grumpy. It's a huge burden. And for what benefit? Damn near nothing in my experience so far.

Full Title (that was too long): Miami Cops Flood Waze With Bogus Speed Trap Data, Don't Understand How Crowd Sourcing Works

I disagree that they don't understand how Crowd Sourcing works. CS is a double edge sword and the hope is that the many will sample out the few. We've seen gaming in Amazon & Yelp Reviews and wholesale cottage industries have been created to "help" (positively) review your product and, perhaps, (negatively) review your competitors.

People are incentivized to better their position and make corrective action when it goes the other way.
I like the article, but on the other side - I hate how he wants a student to complaint.
Why he puts his own student in a situation where he suggest he should complaint?
Why he tell student how much money does he make?
I find this non-professional.
If he have a problem with this - him and other contractors should do something about it, not looking for others to find a solution.
This is very socialist way of looking at solution.

I am not agreeing about how schooling system works as imo it should be all results based - eg. minimum wage + results based bonus. As an addition any sick days/pension would be calculated on average yearly wages adjusted by days off. This way universities would get rid of teachers that cannot deliver the results, scientists that do everything to stay on payroll without doing anything and more.

System like that would promote teachers to spend occasionally overtime teaching students to maintain good results.
And since testing would be done independently - it would be fool proof system. As close to capitalism as you can get in a schooling system.
Hey,

I am the founder of the company providing the pluginless peer-to-peer video streaming service the article is talking about (www.streamroot.io).

>-- residential/mobile internet service has asymmetric upload/download speeds.

Indeed, but it is not so much of an issue: 1. the average video stream bitrate today is 1.5 Mbps, which is closer to the upstream limits than the downstream limits. 2. Our solution is hybrid, so if you can't get all the data from other peers, you just get the rest from the CDN, so even if someone has a 100 kbps uplink, he still contributes to the swarm. 3. With fiber there are more and more people having 100+ Mbps uplink, and these people can serve dozens of others peers, and this balances the asymmetry partially.

>-- ISPs are suspicious of heavy uploads originating from residential homes and could be flagged as "servers" in violation of ISP's TOS or reclassified as "business" thereby increasing the billing amount.

This must be different depending your country and ISP, but the upside comparing to some full P2P service like Bittorent is that you share video segments only while you are on the streamer webpage (as soon as you close your tab the p2p stops), and also all the communications are encrypted with DTLS provided by WebRTC, so it is not so easy for ISPs to figure out what is exchanged.
And finally, we actually help the ISPs by connecting the peers that use the same ISPs, and are on the same sub-networks first, so they have less peering issues.

>-- too much latency for live mega events (World Cup, etc) because of asymmetry mentioned above. (Your neighbor tweets that Spain scored the winning goal before your P2P stream received the last packets showing that it happened.) Latency for bittorrent is ok, but for live megaevents, no.

I think that this where our technology really differentiates with the old peer-to-peer systems : we don't add any additional latency to the stream, but just use the latency already generated by HTTP streaming protocols like HLS or MPEG-DASH. So with or without our system, you will still have a 20-30 seconds latency with the encoder, as it is already the case with all the professional live streams like the ones used during Superbowl or the World Cup.

As for CDNs cooperating to broadcast a live stream, it is not really the spirit of the CDN market right now, instead what happens is that the Broadcaster can contract one or several backup CDNs for their biggest events, and use them in case the primary CDNs breaks down. This is what happened for the Superbowl stream : NBC had Akamai as their primary CDN, and Level3 as a backup. In the end they didn't have to use the backup, but still paid both CDNs for the event !
We actually joke about it! Take a 'bitfield' for example, in french it becomes a 'field of cocks' :)
The Black Magic of Java Method Dispatch
Some companies have battery technology they believe is good for 10,000 [1] or even 16,000 [2] cycles until it reaches 80% of its initial capacity.

On the other hand, some batteries on the market show substantial capacity loss after just 300 cycles [3].

Needless to say, the product that lasts 50 times longer costs quite a bit more - and they're bigger and heavier to boot. For stationary power storage, you don't care if they're big and heavy, but for transport applications you do.

I think this analysis is an oversimplification. It is clear on the graphic that the revenue is growing at a fast pace, and the net income is also growing, but a slower pace.

What that means, is that Google is reinvesting a lot of its revenue in growing other lines of business and creating new lines of business, like Amazon does, not that it generates more money in revenue every year and their costs are also higher each year.

Think Android, and many other lines of business, and one in special which is almost ready to start making money, and it will probably dwarf the ad revenue: Self driving cars, specially now that they're creating an Uber competitor. I know, Tesla, BMW, Mercedes-Benz et al are also working on self-driving cars, but still...

Also, Google is always innovating with new products, some of them can be a success or a fail, or maybe they're ahead of their time (like Google Glass, I'd say)

Google is also making huge investments and research in deep learning (as is also doing Microsoft, and IBM)

Finally there's Google Ventures, which is always investing in promising companies, some of which can be the next billion dollar company.

So I'd say that the analysis is quite inaccurate.

I'm glad to hear you didn't have trouble with those bugs. They actually prevented new packages from building in Debian and Fedora, due to our unit tests catching the bugs, and we had to do a double-release on one day to fix them -- quite stressful for us. Anyway, it's a nice thing you weren't directly affected.

Utilities won't be happy about thus. They are already upset about having people with rooftop solar selling to the grid (taking their revenue); this will only make it worse.

Elon definitely sells solar panels as well. Tesla has already started providing a few battery packs to solar city [0] (which Elon helped his cousin's start) for storing energy from solar panels.

I am wondering where you are that the electrical power allows you to have real time pricing. I think in California some of the utilities have already banned people from using battery packs to help smooth out the grid while gaining money from it.

[0]: http://www.solarcity.com/residential/energy-storage
Losing power from snowstorms (well ice storms really) is quite common in New England and many family members have dropped $5k on propane generators. If you can bring this battery down to that price you will catch all those customers as well as have distributed off peak storage capacity. Right now the best way to store power is to pump water uphill, seriously.
The problem is, selling it back to the grid only works when it's a fairly small fraction of the customer base that's doing it. We can't _all_ sell power back to the grid.

EDIT: Why the downvotes? This is a real issue... The current model of 'buy solar panels and pay for them by selling power back to the grid' will not scale forever...
Load Balancer in the Application Layer: Results Are Impressive
I hate that. The half page of code is not Lisp. Not even close, and I'm not talking about a standard library. There is no parser in there. Eval is operating on Lisp data, not lisp source code. There is no support for efficient math, or strings, or anything really.

If that is lisp, then a byte code interpreter loop is every interpreted language: read_opcode, inc_pc, call a function indexed from a list indexed by opcode. It can be written in one line of C. This BTW translates to hardware a lot easier than the half page of Lisp. That one line of code by itself is also just as useless as the half page of Lisp.

It's still interesting, but people need to stop claiming it's Lisp defined in this tiny little block of code.
Well, depends on location ... I think mine was down around -10F last night and I don't have room for one in a heated space.

I suspect it will be a while longer before battery technology is as useful above the 49th parallel.
I don't really buy this for higher education in general, there's too much diversity in funding and ownership, and it's much cheaper to build and pay for your own school (which the Kochs have done).

Public education I think there is much more evidence of systematic undermining. But that could be more about misguided ideological libertarianism rather than an actual desire to undermine the country. That's the trouble with ideology - empirical evidence can't sway you until it's too late.

I also have had a much better experience with ex-military types than not, in terms of their management abilities, and a fairly representative mix of political ideology too (they're not all conservatives).
Batteries for transport applications have to trade off size and weight as well as the constraints of price, capacity and cycle life.

Stationary power storage applications can use larger batteries with worse power density, if they offer a longer life per $.
This can only accelerate linkedin becoming (more) irrelevant which is not a bad thing in my opinion. I keep a linkedin (basic) profile because it's handy to stay in touch with work acquaintances and keep doors open. But for the love of God, no, I will not grant you access to my address book. No, Mr. Headhunter, you may not have my resume before showing me an actual opportunity.

Linkedin is now eerily similar to Facebook (which I shun) with work anniversaries, timelines, "You may know" and "you may be interested in" lists and all this other nonsense. It's nothing more than a trolling site for headhunters and large corps to pick off low-hanging fruit.

No big loss.
That can be cached if there's only one system. And BitTorrent DHT takes about 30s to start finding peers. That's a very old type of DHT, a new protocol could prioritize finding closer neighbors.

I wonder if they should also market this to the whole house backup generator market? Those run 2,000-4,000 $ at least, I think.

I'd imagine a lot of houses would pay $1500 for a battery to operate their whole house during an outage.

Another product I'd like to see is a plug in battery to operate the sump pump for a few hours during an outage? Apparently a UPS can't handle the high load, and the battery backup ones you make require an expensive plumbing visit to install the special DC powered pump.
From the headline I thought it would be about using your electric car as a gigantic powerbank for the house.

...which is not such a bad idea (e.g. power outages), until you realise that you might need that power for driving too.
I was referring to Mithril and Mercury. I work on a huge React app :)
They should be, but they won't be. Because it makes people less dependent upon them.

If you bought one of these and enough solar panels you could go completely off-grid. Which the power companies desperately don't want. It's to the point where they're charging people for being hooked up at all, lest everyone think about putting in solar and only buying power when the sun isn't shining.

The utilities would be happy about this if they controlled it, but they won't because the capital expense would be way too high. They'll only be happy about it if they somehow are the only ones who have control and get to use it for free. Somehow I doubt that'll happen.
'Pumping water uphill' will likely always be a very good way to store power at those scales. I would take a pretty spectacular number of batteries to match the stored energy potential of a small lake with a couple hundred feet of head.
Some universities have started teaching-track positions: "lecturer" or "teaching professor." These folks teach a lot, are not hired for research in physics, may do research or publish in physics education, take care of training TAs and setting lower-level curricula, etc. These folks also have a somewhat permanent position with benefits, aka a "real job." I think it's a possible appropriate response to a world in which, as you say, the career of a normal prof is a function of their research contribution and grant-writing is increasingly time-consuming. There is no reason that we should allow a situation in which students pay a lot of money to go learn and then are taught by poorly-paid temp workers without an office for office hours or grad students who have less experience than a seven-year-old who lectures to her dolls.

(Not slamming the grad students here -- I've been one. Started teaching on a Tuesday, started grad classes the next day, had 3 hours of instruction on teaching the previous week to prepare me.)

Also, I resent your insinuation that profs have to teach well! ;) Maybe in Canada...
I think that line may mean that people could charge up with the company supplied charger then go home and use it there. It's an expensive way to get your employer to pay your power bill.

In any case, I agree that it's a confusing statement.
