I'd say that Caesar was a very successful warlord, but there were others before him, Sulla and Marius come to mind. The real revolutionary figure was Augustus, he made conscious choices not to reestablish decisionmaking in the senate.
A well done complex system, turns invisible, because complexity is severely reduced wherever you can.

I know we engineers are getting high on it, but if you remove complex components, everyone else is much happier.

Really good complex systems thus, are seemingly simple systems, that cover with stupid components a suprisingly big number of uses-cases.
> Namely, they wanted to make a straight shot from LA to San Francisco by running along the flat, government-owned I-5 corridor with spurs out to the eastern Central Valley, whereas the California High Speed Rail Authority (CHSRA) and state politicians wanted the main line to go through every little town in the Central Valley, directly.

For Germans, this is nothing new. Local/regional politicians always want to have the ICE (Intercity Express, our version of high-speed rail) stop in their more or less tiny village.

The problem is almost always that the villages lack adequate rail connections to the next hub, and I imagine that this problem is even more expressed in the US, given the near total lack of passenger rail...
Buying anything above, say, 100€? Smile, say 'discount?' and they will through in something for free or give a few percent off.

And that's before any kind of negotiation (unless you count asking nicely as negotiation). And I mean anything. I've done it in many places. Is there anywhere where that does not work?
Nice talking point. Locals actually use roads. They will never use this "bullet" train to go to cities hundreds of miles away from where they live and work.
While I agree with you that this demo is suspect, I think your comment would be more useful if you backed it up with some of the physics/engineering principles that support your point of view.
I think you may be confusing friend network and business network. After 10 years in the field, it is inacceptable that you don't have at least a dozen of past colleagues to call to get an internal referral. I personally don't use Facebook but it doesn't strike me as the best platform for that. Your buddies and college friends are one thing, your ex coworkers/reports/managers are another.

TBH, it should be easy to find a gig simply by applying to open positions that you find on interesting companies websites. However, I strongly recommend that you start working more seriously on your professional network in the future. Make sure you keep in touch with good colleagues, make sure you remain in good terms with everybody, etc.
Einstein(aka metamind.io) lets you to upload your own tagged dataset of images which are then automagically processed (automatic hyper parameter tuning?) into ready to use model.

AFAIK Google uses their own model to classify images and on AWS you'd have to setup your own learning infrastructure.

One interesting thing that Salesforce recently released is Einstein Discovery (https://trailhead.sdd.salesforce.com/) - it shows how your data relates and contributes to some sort of goal.

But yeah this is just wrapper for their REST API that's a few years old.
Yea, often when people say "cash" they're just referring to an instant asset transfer (cash, check, eft, etc). Usually I would expect a transaction in a dealership be a check or some kind of electric transaction.

Sounds fun to pull out a large stack of actual cash, though.
I tried to buy a Mazda car outright. I was told that it would be 2000 dollars more expensive unless I finance.

I then asked if I can get the loan and immediately pay it off, and the dealership became sad. Apparently, Mazda financing gives them the 2000 dollars, but if the customer pays off the loan in less than 6 months, the dealership losses the money (on other states, they'd probably have an early repayment fee on the loan, but that's illegal in California).

So, I took the loan, paid off all but a thousand dollars, and now feel silly paying off the remainder over 6 months.

Sigh. Another unique pleasure of HN.

Sometimes there's a difference between practical and possible. I did not say it was not possible. While you're technically correct, the worst kind of correct, very little content and few delivery systems actually utilize that capability -- look how much you had to type just to get there. Then how are you going to deliver that alternate colorspace content? To wit: I note you've overlooked ATSC and other delivery mechanisms, as well as HDMI being a specification designed to handle all cases including non-NTSC-legacy regions which had a different colorspace all along (notably PAL, which defined "blanking" and "black" as equivalent).

Practically speaking, pretty much no content you'll ever play makes use of wide gamut in North American contexts. If you're cooking a file for yourself, that's one thing, but once you're producing something that's mass consumed there's a lot of compatibility issues to worry about. We still have fractional frame rates and picture safe zones, for crying out loud, despite drop frames being pointless for decades and overscan being a word nobody under 30 has heard. What's the point of leveraging wide gamut in HDMI if all your capture equipment, editing tech, broadcast delivery, playback equipment, and displays cannot handle it? For the general case you're counting on Vizio adding that ability into a $200 TV and Comcast handling it in their CPE. Good luck.

Why does that matter? When producing video content handling a wide array of distribution media matters. Except for circumstances where you control the entire system end to end, such as a planetarium or some other kind of venue, you always have to plan for your content potentially being sent over lame, legacy-style HDTV broadcasting. That's the floor. Sometimes you even have to think about SDTV transmission; God help you, and have fun with chyrons...

Not even Rec. 2020, which is designed for UHD and is way better, changed this[0]. It's not a concept that's in dispute, despite whatever HDMI -- one standard of several hundred that are involved in delivering you a single TV broadcast -- can do.

For those interested, here is a rebuttal article, also from 2012: http://www.cahsrblog.com/2012/07/new-evidence-shows-flaws-in...
This kind of technically unfeasible product scam is surprisingly common. When I worked for a large Internet company years ago they were looking at an investment in a start-up that claimed to transmit gigabits through high voltage long distance power transmission lines. No amount of citing Shannon and pointing out that said transmission lines are built with fiber lashed to the ground wire would dissuade them. And these were technically educated people.
> The sensors + batteries in the box is an absurd claim.

No more absurd than that uBeam will deliver meaningful power using ultrasound. So if they are going to show a demo that does what they claimed originally then the contents of the box would definitely be subject to scrutiny.

I've had a really nice rigged demo tried on me during a tech DD once and that tech was a lot more believable than what is on display here so some skepticism is warranted.

Also note that the 'charging' indicator lighting up is mostly a function of applied voltage and not so much of the current flowing, even a tiny bit of current would do the trick.

I should measure with one of the phones here and a variable power supply what it takes to get that indicator to come on but I know it can't be much because a small solar cell will do it too.

Yeah, sorry about that, I've gotten hypersensitive from all the rust hate blogs. It isn't perfect but as you say, it is the best mix for my uses that has come along. My pain points are similar to the article author's. But in addition I have trouble with the way batteries included is implemented. It is still cumbersome to developed without internet access in rust, which is something I do often.
You are a smarty pants, and you know it. You're just not a billionaire with many, many, many subject matter experts in the field of rocketry working for you. No need to compare yourself to others :)
The idea of not paying cash for a car is insane to me. A could justify a loan for a house, or even an education. But a car?! I just don't even understand this mindset.
Yes, I mentioned phased arrays in my earlier comment. Even so that's a lot less focused than what you might believe it does, it's more like a directional wavefront than a focused beam. So you'll still lose lots of power due to the expanding wavefront (conveniently left out of the wikipedia drawings but I can see why they did that).
Think how happy locals will be then that the people traveling farther aren't clogging up the roads.

Bad title. For you, yes, Go makes sense. But for millions of other people, PHP is fine. The title of your post makes it sound like everyone should suddenly switch.

i.e., "For our company, and the extreme performance we need, Go beats PHP"

MySQL? Seriously? ha
I also think that people get way too hung up on the SF to LA bit. Where the California HSR is about a lot more than just that. The SF -> LA -> San Diego part is actually mostly about freeing up airports to handle longer distance national and international traffic.

The central valley part is to tie the central valley cities to the each other and to the coastal cities. I think another part to is try to reduce future sprawl of the central valley cities. Much as people in Bakersfield and Fresno may hate that, it's the right thing to do going forward.

Other part that is totally ignored is that most of the riders will be commuters similar to BART. They won't go from SF to LA, but from SF to San Jose, or Morgan Hill to San Jose, etc.
Zones was the logical conclusion to FreeBSD jail work. They added the full features jails now has finished. Each zone getting its own IP stack for instance. Jails didn't have that in the beginning. It was written by one guy to simply offer a basic but secure container for running multiple web servers in isolation from the host. Had he had the resources of sun Microsystems I'm sure he would have had all the features zones had from the start. But one man can only do so much with finite resources. And the main design goal was security and isolation. Which was accomplished. Separate network stacks was added later.

I'm glad to hear your using it. I really can't imagine using anything else. Open source or commercial. Nothing is as compelling or reliable and easy to use. Me personally, i am forever grateful for Sun open sourcing it. I remember pre zfs days, with volume managers, and how hard it was to grow a ufs/ffs anything, just an absolute nightmare. And backups? Ugh. Tapes. Hoping every bit was copied, but never really knowing for sure. Just ugh. The pain.

I've heard bcachefs talked about to. And as you originally stated I think these folks writing btrfs and bcachefs are talented and are doing the best they can but again FS's are hard. Look at all the garbage we've been stuck with from all the major commercial vendors until ZFS. Everything Microsoft puked up, or Apple, even the major UNIX vendors sucked at making file systems and volume management. Veritas? I'd rather stab my eyes with soldering irons than use any of that stuff ever again. Seriously ZFS compared to all of them is night and day. I'll never be able to thank the developers enough for helping me out of the pit of filesystem and volume management hell. I'll be interested to see how bcachefs ends up. But mostly I think everyone will be trying to play catch up to ZFS and more than likely doing it poorly. But I applaud their efforts to try!

Thanks for the links btw, I always enjoy reading up on various tech.
To the best of my knowledge there's not even any known mathematical theorem that would prevent such algorithms on regular computers. I don't see how this would be any different for quantum computers.
Look at the pace at which the battery is charging on the smartphones. That's not even possible with a wired connection. If they're pumping that much energy through the air I imagine they would be dead already?
I'd just like to reiterate how utterly amazing MusicBrainz is. It's so extremely useful that I decided to make it the backbone of a new playlist format I developed[1], one which (roughly) uses MusicBrainz IDs instead of filenames for playlists.

This makes playlists resistant to filename changes, moves, or even losing all the actual audio tracks and having to buy them again, all because MusicBrainz provides so accurate metadata.

The inverse square law generally applies for focused beams as well. Why wouldn't it?

ICO is just a few years old - it's typical for the disrupted to not feel threatened until it's too late. This, in my mind, is the real model going forward. Fuck pandering to Sand Hill road or SV at all - launch an ICO from anywhere in the world on your whitepaper and testnet (shaky???) dev...

ICO's may seem ridic, but this is just the beginning. We are now running at internet speed and there's gonna be a point (soon? who knows when) where this stuff is going to all be automated and 24 seconds will seem quaint.

The reporters didn't see a tear down of the sleeves, and wouldn't be able to identify a battery if they had. They showed sleeves and a charging indicator, rather than a simple wattmeter. This was a fraud—though like many inventors of perpetual motion machines, it is plausible Perry first fooled herself that the battery in the sleeve is just "to cover the initial surge" or "until we can fix this efficiency problem."

The important lesson here is that USA Today and similar papers can be fooled by a rigged demo and a sincere voice. Read the front page with similar skepticism!
Crime and Guilt is completely unlike either of the Feynman memoirs. It is a compilation of two separate short story collections that were originally published in German. The author is a German criminal defense attorney and the stories are fictionalized accounts of some of his cases. I probably should have listed it under Fiction. It is not an uplifting read and some of the stories are quite brutal. I recommended Crime and Guilt because it portrays the best and worst of human beings. You will read about a bank robber who starts a new life in Ethiopia. Another story is about the author defending a nameless assassin. A third is about a petty burglar who steals from the wrong victim.

If you are on MySQL RDS, the first thing you need to do is change the INNODB_LOG_FILE_SIZE to something reasonable, like 2 gigs. I have preemptively stopped at least 5 vertical scaling requests with this one change.

The default of 128mb is plain stupid. I get why Amazon chose it, because it directly eats 2x the value of your backing store - something that can be hard to explain to customers with 4gb disks attached and not really running any appreciable load through it.

But when you have 100+ gig disks allocated on a 2xlarge instance, the small value makes no sense whatsoever.
It was fun for me. The salesman didn't seem to enjoy it, but, in my defense, I had told him I didn't want to wait a weekend for the SEPA transfer to reach their bank before I could get my new car.
I noticed that the people saying this type of financing is a good deal, were comparing it against just buying a new car outright. But, you don't have to buy a new car.

Why would I need more than one credit card? (Is this some kind of betting game?) How about a card that holds all the cards in my wallet, credit or otherwise? Can Fuze do this?

This reminds me a startup that was at techcrunch disrupt a few years ago. Cota[1]

The tech seems to be the same whereas it tracks the position of the device then beams the power. Note however that Cota only sends one WATT of power per device.

How much does UBeam sends?

I've seen this book recommended many times. I read a few chapters and don't feel like it was useful. Some of the stuff is obvious common sense like smile don't criticize others, be a good listener etc. Then it tells you to be genuinely interested in someone. How can you force yourself to be interested in someone?

Does the book go into anything actually useful later on?

Taking a quick look at this it doesn't seem to offer much more over AWS. Device management and remote access might be nice. But its been my experience in B2B land that anything like this gets locked down by internal IT depts.

It might be a useful service for B2C devices though.
In Ireland, mortgage offers at least have to have plain-English warnings, illustrations of the numbers involved in paying it off, etc. Never got a PCP, but I assume it's similar. The problem is, people don't read them. To be useful, you'd arguably need to give the borrower an exam in what they're signing (which might be a good approach).

PCPs, in particular, are complex as far as consumer finance goes, and a lot of people seem to sign them thinking they're a normal loan. An analogy seem to be the (now thankfully almost obsolete) endowment mortgages, where you took out an interest-only mortgage coupled with an investment product which was theoretically meant to pay off the principal on maturity. These ran into difficulty when inflation dropped to practically zero for a decade, and lots of people who had them thought they just had repayment mortgages...
Their claims are even more suspect than uBeam's.
My explanation is that they've done the math on how more generous financing encourages more people to buy cars, and that the losses they take on the loans is less than the extra profit they make from the additional car sales.
So you're saying this whole paper could have been avoided if they just used clang. And it seems you're right.
Trading is not a zero sum game. It doesn't matter if nothing's being made, that's not the point. It's an important service providing pricing and liquidity which facilitates capital allocation, diversification, and risk management. Trading is an absolutely essential part of the economy.

As a simple example, a farmer hedges his wheat crop selling wheat futures. That allows him to reduce some of his risk, thereby allowing him to plant more (i.e. growing the economy). The market marker who bought the wheat futures may be trading multiple commodities. This trade diversifies his risk, allowing him to trade more of other commodities, allowing other farmers to offset more of their risks (i.e. growing the economy). Investment companies or hedge funds enter the market purchasing futures, to diversify their risks, allowing them to invest more in equity markets, which fund companies (i.e. growing the economy).

If my point isn't already clear, markets and trading facilitate the diversification and allocation of risk capital to market participants thereby growing the economy. It's the conduit for capital which does make something.

The picture shows a 32 x 32 array of small ultrasonic emitters. So that's 1024 emitters. The framed area is about 200mm square, so each emitter has a diameter of about 6mm. That's unusually small; typical diameters are 9mm to 20mm. I haven't been able to find the source of that transducer, but a similar one 9mm across is here.[1]

That one can deliver 112dB sound pressure at 30cm range. 1000 of those would deliver 142dB at 40KHz. (10x = 10dB). If they're all wired to one amp, you get a straight beam. The demo indicates they're only getting a straight beam; steering the beam requires electronics behind each transducer. Quite possible, but runs up the cost. If they wire up the transducers in rings and drive them with slightly different phases, they can tighten up the beam focus. Since the receiver is smaller than the transmitter, focusing would help.
Frequency is probably around 40KHz; if you go higher, losses in air go way up.

I haven't worked out the drive power for this thing, but it's probably a few watts per transducer, or a few kilowatts for the whole array.

So they have a 142dBA 40Khz beam about 200mm square. They ought to be able to do some
short-range charging with it.

Notes:

* That's a high-powered ultrasonic beam. Is it hazardous? Most of the literature on ultrasonic safety involves energy coupled directly to skin, as with ultrasonic scanning,
where there's a gel to improve transmission. Generating high energy in air is rarely done.
It's certainly going to heat up anything in the beam. The safety issue is a big deal. All that energy has to go somewhere.

* How far can they project this? At 40KHz, meters, maybe tens of meters.[2]
Attenuation gets much worse with frequency, so this thing probably works in the low ultrasonic range. Early PR from UBeam talked about megahertz ultrasound, but the range would be a few millimeters up there.

* Efficiency is terrible. Kilowatts in, watts out.

* That array of transducers isn't cheap. Those things are usually a few dollars each. But in quantity, that could come down.

So the demo they did, at under 1m range, is possible, but doesn't mean it's a useful technology.

I've given up on tex. I'm typesetting a book right now, and getting the epub going was a piece of cake. Then I tried using LibreOffice for the print version and it was a nightmare to control via the API and buggy as hell. So I decided now would be a good time to try tex. After 2 solid days of yak shaving, I threw in the towel. It's too fragmented, the documentation is terrible (complete - all 600 pages worth, but terrible for discovery or learning). It's basically rabbit hole after rabbit hole, with most, if not all, tutorials directed towards typesetting your homework assignments.

All of the CSS/HTML based solutions cost thousands per license, so that's out.

I'm now on to SILE, which fixes a lot of problems with tex. I can only hope that it's advanced enough to properly typeset a novel.
