So ... can anyone comment on the assertions in there that LDAP replication is easier/better than RDBMS replication?

The data backend is not my area of expertise but in working with a competitor stack with an LDAP datastore lately the fact that the backend store was not a database, does not seem to be that performant and is not really transactional has been a pain point. Effectively having to mimic relational structures using embedded JSON in sub-attributes seems like a terrible way to carry on - I have no idea if Gluu makes you work this way, but again, the competitor seemed to.
Also most top loading combined models are like this.
So how does having more realistic grades (i.e. not everyone gets B or above) feel when it comes to graduate admissions?

I went to the university with the hardest admissions score for EE, some of the brightest people I've met, graded on a curve, and yet for graduate admissions I'm competing with people who took much easier classes and ALL have much better marks. The GPA system is just insane really.

How to Hide AWS EC2 Instances from Network Scanning Bots Using IPv6

Good weight distribution in ICE cars is pretty exotic. Only fairly performance optimized ICE cars like a Porsche Cayman, BMW m3, and similar performance oriented cars get the ideal 50/50 distribution.

Changing that weight distribution is very expensive from a R&D perspective. Sometimes the battery is moved, or the engine is moved a few inches relative to the front axle. This is one of the reasons performance oriented cars are often rather large compared to their usable interior volumes.

Battery operated cars do have a weight penalty, but you can put that weight wherever you want. You could relatively trivially make a 50/50 distributor of significantly front or rear biased with no substantial R&D overhead or loss of efficiency.

For instance the Tesla model 3 not only has a very low center of gravity, but also a very low polar momentum. In an ice car that would require a mid engine design (like a Ferrari, Lamborghini, or the newest Corvette. While having an large usable volume, more like a bmw 5 series than a 3).

So basically weight distribution is easy to tweak with batteries, and even with the weight penalty have a substantial lead in efficiency.

You are spouting nonsense. Use of oil and gas isn't a matter of "belief". It's a function of demographic, developmental and economic variables. Pretty much the energy use for the next decade or two is nearly set in stone barring fusion energy.

Also, if you think going from gas cars to EV is a greater jump than horse buggy to automobiles, then you simply don't have a clue. As for china and india, EVs account for 0.0001% of cars.

If you think we are going to be using "all electric aircraft" at the end of this decade and that it will dent the need for oil for air travel, once again, you haven't a clue what you are talking about.

If you think natural gas growth is going to slow anytime soon, once again you haven't a clue what you are talking about. The bigger growth in energy has been in natural gas. It has solely been responsible for the collapse of the coal industry in the US. And there are tremendous room for growth in natural gas production in the US, Russia, etc.

> Your peak oil will be in the past once you see entire areas of housing in BRIC countries running on Solar/batteries. Goodbye. Oil.

Dumbest thing I've ever read. It much more likely that these countries are going to increase coal production to keep up with energy demand needs than going "solar/battery" route.

> War profiteers say the same thing. They never come out on the right side of the history book.

Nope. This is the dumbest thing I've ever read. War profiteers are some of the biggest winners we have.

> Oil and Gas will NOT have growth for a long time.

If you say so. But then again, people like you were claiming the end of oil a decade ago.
The “disrupters” are usually “pulled out” disproportionately if they are poor or minorities while kids who do the same thing but have more influential families get a “counseling”.

I think that there is relatively little weighting to food science here and relatively high weighting towards technocratic administration, which predicts (correctly) that neither Krispy Kreme franchisees nor donut couriers have done a risk assessment and therefore is extremely prescriptive about the paper trail you need to have to exempt you from broadly applicable practices.

Grocery stores are an example. They're professionalized infrastructure! The regulator knows their safety record individually, as a class, and feels regulatory-warm-fuzzies over knowing that there is a named individual at the store responsible for food safety and who files a report weekly saying "Story this week same as the last week; we checked everything you want checked and there were no anomalies, because we made it so."

Actually worse than other cryptocurrencies. Because Tether can collapse if (when) they are found guilty. The "normal" cryptocurrencies can collapse only when the market as a whole says so.
I'm also not sure, and values are always population dependent, but simply the fact that land (and nature on it) is one of the most scarce resource nowadays, it seems straightforward to say that if we price in land use compact wins over sprawl.

I agree that there's enough energy and stuff in theory to be green and live anywhere, but currently in practice there isn't. (For example just now with the PG&E blackouts the very real cost of living spread out shows itself.) At the same time you are correct that if some pandemic strikes it might be better in a log cabin, but ... for how long? Are you ready to hunt? Grow your own wheat, and so on? And HongKong seems to be doing fine, after SARS they are doing a lot of proactive stuff.
For instance Ottawa to Montreal is a "17 minute flight" that takes an hour of block time, and an hour on either end, for a total of 3h, or you could take the 1h 30m train ride along standard-speed rail for $20 USD.

The even better comparison, while not in America, is the route from Tokyo to Osaka. The distance (506km) is almost the same as from LA to San Francisco.

The Shinkansen takes between 135 and 153 minutes. Granted, you have to get from Shin Osaka to the city center; an additional 4 minute train ride or you take the subway.

Let's not even get into the comparison of the travel experience between gliding in a quiet, serene manner on spacious seat past Fuji San with the experience you get in a middle seat with a 29" seat pitch in economy class of a domestic flight in the US.

Also, if you invest a few hundred yen into a bento at Tokyo station let's not even think about the comparison of the culinary delights awaiting you for the trip.
How do we know?

I mean if they increased their prices by 10%, their sales quantity would certainly decrease. So to make that 10% revenue increase would take potentially a significantly greater price increase, substantially changing their value proposition.

Granted most studies show that demand for ridesharing is inelastic at current prices, it says nothing about switching to Lyft etc...
> Patents are helpful when you are small, and cannot win the scale war

That's a very naive view of things.

Big companies will be happy to license your stuff if they actually got something with it (an actual developed product or component) but they won't be much compelled to license if you just wave a patent in front of them.

"Oh but then you sue", yea, it's not that simple.

Here's a foolish idea: can we patent patent trolling?

Parhaps a patent on some electronics means for discovery of targets for specious patent claims. Or a patent on some 'novel' business process that patent trolls could be argued to rely on. Something sufficiently broad that might be weaponised against patent trolls.

Have I just ruined the patent trolling patent by creating prior art?

Train stations tend to be located right downtown whereas airports, for various reasons, far outside. You can't exclude that delta.

SFO is in San Mateo, the next county over -- almost 15 miles away. Oakland airport is closer to 20 miles away. A minimum of 30 minutes by car, 40 minutes by Bart from downtown SF. On the other hand, the high-speed rail link would pick up at the Salesforce Transit Center (Embarcadero Station) at the corner Howard and Fremont, stopping at San Jose Diridon station.

Yes plaines are fast in the air, that's not a surprise. However, they're epically slow when parked at the gate while you clear security, epically slow as they taxi, dead stopped as they wait to take off due to ATC hold and weather issues, and similarly dead stopped when they're waiting for the previous plane to clear the gate at the destination airport, while you wait in line to get off, and while you wait for your bags, and while you wait for your taxi.

C'mon now. "Plane go fast" is just a small part of the story, and I'm an AA EXP.

Again, I think the infrastructure costs in the US tend to be massively overinflated due to graft instead of actual cost.
I agree.

One thing that strikes me is how many go undocumented - including mutations that cause HIV immunity.

Probably not. Nobody knows the full story, but given that the pattern is one of responding to market movements rather than looking like money flowing in to a market from investors, it seems unlikely.

Further, given their outright lies about auditing and the recent admission that only 75% of tether is backed by cash or cash-like instruments, it looks a lot like a huge fraud to me.

Make your own mind up I guess, but if you're going to tell me "See, nobody actually knows!", then that's true. But we can analyse what looks likely, and what looks likely is that it's been issued out of thin air to prop up the market price of BTC and fleece market participants for the benefit of owners of the Tether corp and Bitfinex.

I guess we'll see more as the various lawsuits shake themselves out.

The degree you get certainly matters for graduate admissions though. For example, at both MacGill and U of Montreal they don't take any account of industry experience when you are applying for grad school. And they assume grade inflation, so unless you scored A average you can give up.

“Growth is only good if widely shared” is a meme that has led to immiseration every time it is implemented. If capitalism has to own child labor, then redistributionists have to own the violent mass scale enslavement of the peasants under Mao/Stalin.
It does require scaling at 4K, no misunderstanding there. The system is unable to scale the UI itself like Windows does and is unusable at either base resolution or 2x - unless you find (and want) an odd 20in 4K monitor.
Great example! Similar thing probably holds for moving main limbs. A good EEG should be able to pick up when you think about moving your hand or leg. I doubt a good EEG could distinguish more than a few dozen patterns. Most experiments have trouble with even a handful of patterns. Still could be useful, but just very limited.
And what are the chances that influential, well connected parents will be sure that their kid ends up in the highest level whether they deserve it or not? I saw this all of the time in school.

On a related metric, if you look at the top 10 students in my public low rated high school in the south, the top 10 students (which I was one) were made up of kids whose parents were in the school system, one kid of a prominent lawyer, one was the daughter of a plant manager, and only one came from a poor background.
"A well intentioned" is a complete miss of a description. The bill is doing exactly what intended. It's evident a bigger corp. can pay bills easier than smaller.
Are those cities or counties populated by more than a few hundred souls? They are too big. This is not 'local' in my book, whatever the denomination (city, county...).

Moreover some/many underlying principles of many "local" laws are induced by higher level governments, either by direct or indirect pressure (no funds granted without such and such law), or by "culture" (local public servants being, or willing to be/resemble, like the big guns).
I hear you. TBH, most popular Linux distros feels very bloated nowadays. The other day I created a VM and there I installed FreeBSD for the first time. The process was really quick. It felt like a breath of fresh air. Much much simpler than what I had imagined. Everything felt very logical. I have thought about this before but since I already knew Linux I was hesitant to take the time to learn another Unix-like OS. But now I feel that I want to carve out some more free time to get more acquainted with FreeBSD. I’m quite sure it will pay off in the end.
Thank you, I will try to read them when time permits. I forgot to mention evolution in my post, but that's part of the point. Our genes seem like a very long-term memory, trough them species (including ours) can learn new strategies over millennia.

I'm not sure what API they are using. The cheapest Places SDK API call is a plain autocomplete and it's still $2.27 per thousand requests. https://cloud.google.com/maps-platform/pricing/sheet/. They say it would cost $1000/mo, but then there are 2.3 million requests in the past 30 days, which would be $5221/mo using the $2.27 price. I guess there could be a volume discount but they don't mention it.

Lowkey.gg (YC S18) is hiring a full-stack engineer (remote possible)
Lowkey.gg is a startup for amateur esports out of Y Combinator, backed by 2 NBA teams and the founders of Plaid + Tinder. Our mission is to provide high-quality esports to the mass of casual players and communities built around gaming.

We just started working with some pro teams (e.g. NRG, 100Thieves, etc) to build out amateur leagues for them, and we're looking for some engineers to help out. We're a very small + technical team out of Harvard, so if you're interested in joining and excited about esports, we'd love to chat.

The setup would be like a part-time remote sort of deal (we'll pay pretty well). Our stack is React/Node/GraphQL/Postgres; there's a ton of stuff to build so you should be reasonably experienced in React at least. If you'd like to know more, please feel free to ping jessetanzhang@gmail.com!
1/3 sounds crazy high.

Most would consider the Tesla Model 3 a luxury car. The BMW 3 series and Telsa model 3 are positioned similarly. Both are $40k-$80k, optionally AWD, sold as performance luxury sedans in a range of different performances. If you want to pick two particular models I'd say the model 3 AWD and the BMW 330i xdrive are very similar.

The BMW weights 3,763 pounds, so the Model 3P weight 4,072, which is just over 8% heavier.

> IMHO, ubiquity, especially when traveling, will ultimately be the winning move.

Many of Uber’s customers are price sensitive. The minority who are not price sensitive are more likely to (be able to afford frequent) travel, but I fail to see how loyalty from this segment will translate into profits over the long term, especially since their international presence in multiple but not homogenous markets is a bet that economies of scale will yield a handsome pay off, where it clearly hasn’t as they had to pull out from direct competition in China for instance.
Short TTLs are bad, but I confess using them in some small scale projects in anticipation of this kind of worst case scenario :)

Prices are pretty flat in eg most of Germany. People mostly buy to consume housing services, ie save on rent.
That’s the point I was trying to make: that the difference between Scorsese’s classics and Marvel blockbusters doesn’t seem to be anything remotely objective (or even subjectively quantifiable) like “level of talent required” or “amount of detail.”
And you have wifi/mobile-net, comfortable seating, a table, power socket.

Now, that said, if the stations are not connected to the cities they are in, then that's a problem. And maybe this is a near unsolvable one, due to costs.
Well users imply trust towards a platform when they hand them their location data in the first place, right?

I imagine that even if you trust the platform holder to handle the data responsibly, you might still worry what someone could do to you if it fell into the wrong hands due to a hack, or some future government that might abuse it.
Well, there's also value as jewelry. But that doesn't distract too much from the point.
This sounds like The Monkey's Paw. They granted you your wish of tracking no personal data, now they can't even verify your account's identity, and their inactive account cleanup job has scheduled you for deletion. Very interesting! The line between necessary data and personal data is a finer one than I thought.
Above all other sites, HN's who's hiring thread is the best way to find devs. Something about the kind of people who read this site is just right.

I've used both HN and various distribution sites, and somehow when you look at where people found us, it's clear HN users seem the best qualified.

It's also kinda interesting that traditional recruiters don't seem to know that HN is a bit of a treasure trove of CVs. At least the financial ones I meet in London are quite surprised I can find someone on some site that only has a hiring thread once a month.
Then he was an idiot, because at the time email was already in heavy use and had been for years, and had had a massive effect on business communication and the economy. Unless for some reason you don't count email as part of 'the internet'?

I was working back then, in 2003. The view on the ground was that SV had blown its head, but the rest of the world was just getting on with it. In fact most of the tech industry didn't even notice or care.

If you want to talk about whether web-based commerce was looking feasible, well even that was healthy enough - amazon was there and people were using it more and more, though clearly it wasn't as big as it is today.

So no, there was no feeling that 'the internet' wasn't going to be such a huge thing. There was a pessimism about some aspects of web commerce.

But I guess that's not as catchy a tagline as "It's like the early internet!"
About a decade ago when I was still in school, I did some work in brain machine interfaces as well as a friend. I made an EEG from scratch, worked on the DSP and amplifications to make it all work, and also had access to a much more expensive state-of-the-art machine. While I didn't work directly on the project with my friend, at the time they came to the conclusion that non-invasive neural processing (so something topical like an EEG, no surgical implants) could process about 1 bit per second of useful information - the noise to signal ratio was about 1000:1. When most people read the raw data from an EEG they don't realize they can't even see the actual data - they're seeing eye movements, facial muscle twitches, and other noise artifacts that overwhelm the actual signal. I'm guessing the technology has improved a lot since then (I'm in another field now), but it's hard to imagine it gaining however many orders of magnitude in resolution necessary for this to be viable.
AFAIK, GDI acceleration came back in Windows 7 (with WDDM 1.1 and later GPU drivers).

Uber & Lyft are in the best position to take advantage of robo-drivers.

I don't think they are. The cost savings on using driveless cars for taxis are huge. Any operator will be able to massively undercut the competition. Consequently the most sensible thing for whichever company gets a level 5 driverless car first would be to run their own ride company and not sell or license the tech to anyone else. That's what Waymo is all about and why Uber are trying to invent their own driverless tech.

Any brand loyalty will evaporate literally overnight as soon as someone launches a driverless ride service simply because it'll be half the price of all the other human-operated services, far more reliable (no more cancellations for a better fare), and probably have many more cars available 24/7.
