The 48 V DC "sweet spot" is mostly safety / regulatory. As soon as you get to 50 V, the safety requirements (NEC) change. You can hold on to bare conductors with a 48 V potential across them just fine, even though 120 V AC will kill you and make it hurt the entire time you are dying.

48 V devices can require connections that are inconvenient and large, depending on what you want to power with them. Try running an air conditioner off 48 V and measuring the peak current draw.

Oh man, Slack really is a beast isn't it? I do like the multiple network nature of it (even though everything is saved to Slack's servers) but I find it hard to believe it does so little for it's footprint.

They too though made a Google-like transition and went from an open protocol (IRC/XMPP) to a closed/custom API. At least here, the server admin can enable those protocols if they want and the API seems to offer enough features that someone could probably integrate Slack into another IRC-like client.

The facebooks and googles can afford to follow GDPR. If you know some people that work there, you'll realize there have been multi-year efforts to become GDPR compliant in those companies.

It's the small companies who literally can't afford the staff to properly implement the GDPR. It looks like it's turning into a regulatory barrier that protects the big guys and scares the small guys away.

There is nothing in the GDPR that says: "if your a small < 5 person corp not in europe that isn't a subsidary of another corporation, then the GDPR does not apply (ie: Joe's blog, Sue's landscaping)". Or "If your revenues & employee counts are within this band, then the maximum fine can only be applied on a percentage basis and not millions.". IF these regulators really didn't want to scare away the small guys, they would of put that into the law.

"Don't worry, the european courts are nice people" is not a strong enough guarantee for most people and corporations.

Alternatively, I may want to own shares because I'm a buy-and-hold investor. An out-of-the-money call solves the FOMO problem.

> "But skeptics may wonder why engineers are devoting so much effort to developing the mild hybrid systems that could be seen as stopgap measures on the path to a fully electric vehicle fleet."

Let's do some napkin math.

Assumptions:

1. Gasoline will never exceed $10/gallon. (assumes eventual plant/algae sourcing/some kind of magic). 1a. Vehicles achieve 50 mpg (2 gallons/ 100 miles) via tricks like 48-volt.

Thus future gasoline MHEV vehicles cost 20 cents/mile to power, so $20 per 100 miles

2. Batteries get stuck at about $100/kWh. (maybe lithium etc never scales) 2a. Consumers are satisfied with 60 kWh batteries.

Thus BEVs cost $6000 more than comparable MHEVs (napkin math)

4. Electricity costs $0.20/kWh (assume some surcharge for the charging station). 4a. Your BEV gets 34 kWh / 100 miles (99 MPGe)

Thus to power your BEV costs $6.8 / 100 miles.

5. The difference between 20 and 6.8 is 13.2 - so you are paying off your battery at $13.2 / 100 miles. 6000/13.2 is about 450

---

Conclusion: It will take 45,000 miles to pay off your battery, assuming the competition is a 50 mpg vehicle and gasoline is $10/gallon.

Additionally, the initial cost for a BEV is $6000 higher, which is quite significant for entry-level buyers.

---

With 33 mpg and $5/g you have $15/100 mile, thus a 80-90,000 mile payoff.

With 33 mpg and $3/g you have $9/100 mile, thus 270,000 mile payoff

With 33 mpg and $2/g you have $6/100 mile, and you will never pay off the battery investment.

With 20 mpg and $3/g you also have $15/100 mile = 90,000

---

Home Solar: add $10,000 to your battery = $16,000

50 mpg and $10/g you have $20/100 mile = 80,000 mile payoff

33 mpg and $ 5/g you have $15/100 mile = 107,000 mile payoff

33 mpg and $ 3/g you have $ 9/100 mile = 179,000 mile payoff

33 mpg and $ 2/g you have $ 6/100 mile = 267,000 mile payoff

20 mpg and $ 3/g you have $15/100 mile = 80,000 mile payoff again

Ask HN: Does anyone have experience with ICANN deletions?
I've been checking up on a domain every once in a while I've wanted that's been squatted on, and noticed this week that it's been put into "pendingDelete" and "redemptionPeriod" status.

Is there any way to check when it'll be open again? The redemptionPeriod status description says that the domain will be deleted 30 days after the redemptionPeriod is set, but doesn't tell when it was set. I'd rather not wake up to find it's been squatted on by a different person after it's deleted, so is there any way to be notified when it's been cleared, or see when statuses for domains were set?

South Korea has this brain-dead law that prohibits any map data on South Korea from being exported: the data must physically remain in a server located in South Korea.

Obviously, this is a huge problem for Google, who wants to keep the world's map data in multiple data centers across the world. So... imagine what kind of horrible kludges some unfortunate developers had to write just to comply with that law.
I never understood why social security counts as “spending”. We all are forced to put money into a fund that mathematically cannot lose money unless life expectancy shoots way up. When we withdraw the money according to plan, the government is not “spending” it.

The fact that congress borrows from the fund and doesn’t pay it back is a problem with the rest of the budget, not social security.

I agree that jbuilder (dune) more or less solved the fragmentation problem for build systems, and is nice to use. I switched most of my projects to it.

On the other hand I'm more pessimistic about the stdlib situation because Base breaks compat with the stdlib, thus making the migration impossible (or really painful) for a lot of projects. I'll therefore stick to my own extension of the stdlib (containers) in the foreseeable future…
I think there are a lot of things susceptible to this kind of analysis.

I also believe that the major jump is not this analysis per se, but the fact that Mr. Musk has access to capital and the ability to follow through beyond the average.
you guys want to talk about frustration and pain from hangouts? pffff, try this:

an important new client calls you on your google voice number, which routs to hangouts. You don't yet have their number as it isn't in your Google Contacts or your Phone Contacts.

You answer, but are busy, or need to look up something for them, and you tell them you'll call them right back.

You get the info you need and you look to your recent calls for the call THAT JUST CAME IN LITERALLY A MINUTE AGO. It's not there. Hangouts does not save incoming calls. (or at least it didn't a year ago)

Why? Who the fuck knows??!

Google has the talent and the flexibility to make the very best instant message client that would be useful for everyone... but they fucked it up somehow.

It means they really don't care, which shows in their product. My chats often get lost or delayed. I can't control my "contact" list, and there is no reason why I shouldn't be able to except they don't want to allow it. I see my friends who have died 3 years ago still on it, and I can't remove them unless I block them. If my contact is "Off the Record" they don't even show up in the list, which is infuriating.

I would love to know the reason why they let Gmail and Gchat go. My killer app for the Mac is iMessage, mainly because it integrates my text messages and Gchat into a single client. It's so convenient throughout the day for me.
Spot on. I strongly recommend Russell's History of Western Philosophy to get a wider perspective and understanding of how and why thought systems evolved, much more insightful than knowing any particular philosophy in a vacuum, and to understand stoicisms place and how it primed the West for Christianity.

It is often claimed that the ancient greeks experimented with every possible philosophical system, of which stoicism is one of many. To me this ultimate freedom of thought, this willingness to challenge and explore ideas without fear of tradition and authority, and to create new ones and following them wherever they may lead, this open mindedness is one of their great contributions.

Of all these, Epicureism is possibly the one that has ultimately triumphed, via Lucrecius' De Rerum Natura. This point of view is wonderfully explained in The Swerve: How the World Became Modern. Absolutely fascinating how by starting by speculating that everyting that exists has an exclusively material substance and is made of atoms (he wasn't the first to speculate this though), Epicureus, via a long chain of reasoning, deducted an ethic that is essentially modern (albeit often misunderstood due to its suppression and distorsion by the christian tradition). 2300 years ago.

I wonder if A Man in Full novel by Tom Wolfe is a precursor of this stoicism trend.

I'm not convinced that Base will solve our problems.
It's not, afaik, more portable, more lightweight, more performant, or more feature-full than [containers](https://github.com/c-cube/ocaml-containers) (which has reached 1.0 and also does a bit of IO and Unix, as a stdlib extension). In addition to that it's not compatible with programs that use the stdlib right now, so the fragmentation will stay for a long time (unlike for build systems where you "only" have to change the build scripts, not the code itself).

(Of course I'm biased too, I wrote containers ^^)
Those are if you are using the APIs directly.

But you can always go straight to the files themselves for cases like Photos and Calendars and also to the SQLite databases that back a lot of user data.

And current location is easy to get on OSX. You can simply look up the user's IP address and WiFi networks to triangulate the user's location with about the same accuracy as Apple can do.

With webcam you can easily switch the camera on, take the photo and switch it off. Could easily trick people into thinking it was a hardware fault rather than something nefarious with the app.

The fact is that none of what I listed above is possible on iOS.
The OpenGL compute shader feature is not needed for doing GPU compute. It's just another type of shader that is not connected to other GL rendering that may be happening at the same time. People have been going GPGPU with the traditional types shaders for a long time. And WebGL 2.0 is a huge upgrade from 1.0 from a GPGPU point of view.

Also, a compute shader extension may be coming[1] for WebGL 2.0, it's mentioned in some meeting slides at least: https://www.khronos.org/assets/uploads/developers/library/20...

The GDPR strikes me as an urexample of regulations gone wrong. If you read some of the later posts in this series, one thing they say is that "the regulation can't be that onerous because this is all best practices anyways." But the reason the regulations are onerous are because what qualifies as falling under the purview is indefinite, and the regulators don't want to clarify so they can use the ambiguities to punch the punching bags when the opportunity arises. So the risk-averse have to assume that the requirements stretch to the truly insane (e.g., requiring an email for anti-spam blog commenting purposes triggering these provisions) with the only guidance really being "we're not really targeting you; we just care about the punching bags."

Replying to myself: One thing the above does not take into account is the feeling of a BEV, which internal combustion and weak hybrids simply cannot match. I deeply feel that luxury customers will demand strong electrified powertrains after experiencing them.

Strong hybrids could match the feeling of a BEV, at a similar per-unit cost.

One issue is engineering and certification costs - manufacturers can only do so much at once or else shareholders get anxious.

Also not included are warranty reserves (how much to set aside per vehicle for warranty costs). More complicated vehicles call for more reserves.

Ask HN: Sentiment analysis on SaaS support tickets?
I'm trying to cover the tickets in our internal support inbox and analyze the sentiments of initial messages to get a general score.

We use Help Scout, and at first their reporting system wouldn't export the body messages because the nature of the threaded conversations. I've written a Ruby script with this gem (https://github.com/hramos/helpscout) to export our conversations. Moving forward I'll run the script at the end of each month and append the deltas to a running sheet.

My question is, now that I have the data, what is the best way to complete sentiment analysis on our support tickets? I want to gauge a better idea of where users have a problem and improve the help resources for those particular topics. Benjamin Brandall analyzed tweets to find how the top Saas companies were using their support twitter channels. I'm looking for some articles to read up on, as I'm more versed to writing my own script to complete the sentiment over a service like Aylien's Text API (cost purposes).
I agree China does not yet surpass all other nations regarding creating innovations in AI, although they have come close to the top of the league.

As shown by PISA and other international tests, the percentage of AI-capable people varies wildly among the populations in that 7.4 billion global pool. China performs very well, esp relative to their development level, and above most OECD countries.

http://ncee.org/2016/12/pisa-2015-results/

If China can hold onto most of its talent, it would be a relatively large percentage (say 4-5%) of 1.4 billion vs a smaller percentage (2.0-2.5%) of 1.3 billion (OECD country populations) and a very small percentage (say 0.2-0.5%) from 4.9 billion (the rest of the world) who can potentially work productively in AI. This assumes the Gaussian distribution of education quality, skills, and perserverance and a fairly high bar (2+ SD above OECD average) for a lower threshold to work competently in AI.

It is obvious that not all talent in the latter two would like to immigrate to the US, so it is unclear if the US will continue to have a quantitative advantage despite a more global talent pool. Chinese government's deliberate policy in nurturing and developing AI talent will also add to the number of local practitioners. There is also clear evidence that more Chinese nationals are moving back home after graduating from abroad.

The rough estimates above are relevant for AI optimizations and applications in many real-world settings since a sufficient quantity of R&D practitioners is necessary for that.

For breakthroughs, other factors might come into play and it is not clear if cultural factors and upbringing would affect the potentials of people to create paradigm-shifting ideas, which means quantitative analysis in isolation is not nearly as predictive.
Funny that. I use Linux because it just works, macs are a pain and windows is just laughable.

What annoys me about the last decadeish of Mac developers is the terrible prevalence of things like "curl|bash", custom pacakage managers, unversioned software etc.

This could just be the company I work for, but as far as I'm concerned software is not released unless there is a collection of software and instructions on installing. Deb, rpm, even a rat all is fine. Anything that downloads something from a random website is not.

Now obviously Mac developers don't enforce this attitude, but it does seem to correlate.

This is so true and I'm certain it's related to the noticeable downgrade in web performance and usability over the past five years. So many sites are flabby and slow now because they're retrieving countless packages from CDN's, each time of course with a ssh handshake, etc etc. You can see endless retrievals flashing on the bottom bar, sometimes literally never stopping, as the site keeps doing one thing after another to anticipate what you might want to do, load new content, or whatever. I find the web only barely enjoyable to use anymore. Even the simplest things seem to blow up now, e.g. very often I get "not found" for the Google homepage. Huh? That one's probably on me somehow, but I'm not doing anything different that I know of, but what has changed that I know of is the extreme increase in complexity of internet delivery and programming. And I will just vent one more pet peeve. Not EVERY part of a web page needs to pop something up in your face when you put the mouse over it. Thank you.
