I think these are great for people with experience using embedded electronics and comfortabke with soldering and low level programming (I.e probably a significant portion of HN readers).

However for those that don't have a background other than simple programming experience, I strongly recommend paying g more for a platform with good infrastructure. For example , I'm really impressed with particle.io.

Board costs are <$20 but come with cloud infrastructure and lots of examples and documentation. For those that value time over money I recommend them.
It's an intellectually dishonest way to de-emphasise how much it costs in total by showing you the smaller monthly amount. You are basically using a marketing trick on yourself to justify the money spent.
The ESP chips are not trivial to hook up, unless you get something like a NodeMCU. The original breakouts are not breadboard friendly, and they have (comparatively) weird requirements for programming (e.g. some pins need to be pulled up, which means you need to breakout the breakout boards). They're also not 5V tolerant, which means you normally need a regulator and have to worry about interfacing. The documentation is OK, but it's a warren of official documentation, Wikis, Github and forum posts.

I would say that the Arduino advantage is that it's truly out of the box. ESP8266 is close, but it's not that easy.

If you want an easy IoT dev board, I will always recommend the Particle Photon (no affiliation). It's $20 and has really great documentation. It will do OTA updates out of the box once you've set it up on your network using a smartphone. It's a separate IDE (cloud based, or you can get an offline one), but you still use Wiring and they've retained the setup() / loop() constructs. I have had some issues with devices not connecting to networks using the chip antenna, so you probably need the external one.

Other minor issues - most ESP boards are not FCC/CE compliant. They're just fake stamps on the EM shield. Some of the boards are, but you need to be careful if you're trying to build a product or worry about interference. The Photon, on the other hand, is certified (and they also certified it with a suitable external antenna).

Seems like an old man is having trouble with change. I'm sure that similar things have been said about cars, telephones, televisions, and computers in general.
And I honestly don't see what's wrong with wanting the status part of it either. When I started web contracting 5 years ago, the first thing I bought with my money was a MacBook Pro to replace my ancient ThinkPad T40. Makes client meetings go that much smoother when you're using the same thing as everyone else.

Geeks always seem to want to erase the human factor out of everything.
Can you link to this? I don’t think this deal happened because Apple doesn’t discount this heavily. Some of their partners might but only in exchange for phone service or something. The SE is $350/$450 USD new, not $250 like the above poster said.
Really? Nobody is paid per month? Coming from the UK that is unexpected. Are jobs wages advertised per week? What are the real advantages? Surely it's a bit harder to pay for larger purchases as it requires more controlled saving and spending?
If I want a low-light camera, I will buy a DSLR/mirrorless, and no smartphone comes even close to something like Sony A7s (~$1100 used). I used to do commercial portrait photography, so I know.

I also dislike the fake background blur / bokeh trend. I understand why the companies are doing it, but it's insanely hard to implement it right, and no phone has achieved it. Every time there's hair involved, they all fail.
I think people are drawn to ML because they've heard they do not need to pick features because the algorithms will find the features for them.
In all fairness, business would be wise to dispense with much of the pointlessly low-level technology it uses. You want to automate a business process? Then formalize the business process itself, not the tool that you think could help you automate it. And do it in a programming language, of course.
The biggest advantage of a truly decentralized system is the lack of corporate control. Take the lowly todo app. If as a regular person you want to keep a todo list and share it with others in editable form, you need to get in bed with a corporate taskmaster. There’s no technological reason why that needs to be the case.
I've often wondered why the us does not have any exit passport controls. It is the only country I've been to that only checks incoming and not outgoing.

I'm not saying they should or shouldn't, just observing.
Okay, so then who will be remembered above all of the other noise in our heads in a thousand years?

Mental real estate is very expensive, and our ability to forget is what allows us to remember the things that are important to us.
$5m is too much for me for a house with no hookup to district heating, running water, dried cow poop as heat insulation, and proper sewage... This is what I don't get about Beijingers or Shanghaites
Where are the people going to come from? UK is already 83% urbanized: https://data.worldbank.org/indicator/SP.URB.TOTL.IN.ZS?year_...

It also hides the opportunity cost. $10/month doesn't sound like much, but $400 could buy something else nice.
In the US, in USD.

An iphone X will be worth around $500 in two years. Your total cost (ignoring service costs obviously) of ownership would be $20-$25 a month (depending upon depreciation and interest costs).

Buying an iphone 8 for $650, and having it worth 50% in two years costs you around $13 per month. Hence iphone X costs only about $10 a month extra.

If you buy a super cheap android phone for $200, it essentially going to be nearly worthless in 2 years. Your cost of ownership is around $6-$8 a month.

And these are devices we use heavily every day. If the benefits of s particular device are useful at all to you, it’s trivial to get the right one. Your monthly service costs are far higher than any specific phone costs.
Netbooting is one of these problems that turns out to be much more difficult than it's inherent complexity warrants. Setting up DHCP and TFTP doesn't cause a full psychosis yet, but then we enter the "no win zone" of NFS and filesystems. One of the persistent frustrations with any sort of Linux filesystem is that their makers feel you would only ever want to use them with a full-blown Linux kernel, too. No libext, the only userland tool you get is a bunch of 10000 LoC C monsters that an autoconf behemoth ensures can only be built on a modern Linux glibc system. When at the end of the day we are talking about an abstraction that should work perfectly fine with just read(), write() and seek().

My ideal "netbooting" setup is a faux SD card that translates block IO to UDP packets on a GBit link and has a little software on my computer reading/writing from a binary blob. I can still mount it if theres something mountable in the blob. Being a SD card it solves the other big problem with netbooting, which is that it's not transparent. The bootloader needs to know it's netbooting. The kernel needs to have support for NFS. init needs to know you are netbooting to mount the differently-named FS. And then when a service decides on startup to reset the network connection (hello Android), you're still fucked.
I've done nursing work, and my brother is an EMT in paramedic training. From the discussions we've had, you can always leave nursing/hospital care if physically able to express that desire and mentally stable, and the only EMT care you can't decline is if you tell them you're going to kill yourself or are physically unable to decline.
this is a bit misleading in that it's not necessarily about netbooting (which per linked article just works).

As someone who's played with raspberry pi's on "real" networks I can tell you that netbooting one is not as reliable as you think. It may work on a small home network, but once you have 50+ devices tftp-ing something will show it's limits.

The firmware that netboots is also not as reliable as one would think. If it fails it just hangs. A proper netboot/PXE client will retry forever.

The approach I followed was to build a minimum ramdisk image which I've placed on the SD card. When that starts, it creates a in-memory file system and downloads the actual image to this file system. The SD card is in read-only mode after that.
To truly benefit from this theoretical advantage, reversible computing requires reversibility at all levels, including the electronics and the program itself. Simply retransmitting a bit requires fan-out which is itself forbidden in reversible circuits, so it doesn't buy you anything.
I'm okay with this aspect of the iPhone X. People buying $1,000 iPhone X's subsidize the technology that goes into a $350 iPhone SE.
Its a luxury, disposable income signalling device. I don't know many tech savvy people with iphones of any kind anymore. Its clearly image and exclusivity driving sales, not features.

I think many people see apple as a luxury brand more than a technology company now. Which might be better than the alternative. 'Anyone' can create tech, it takes years and billions to create a valuable brand.

Dear Golang...
No, as usual the GOP doesn't remove anything, they just make it as difficult as possible for anything to receive the funding it needs, and then go on TV and moan about how nothing the Government runs works properly.
I bought a huawei 4g mobile wifi device off ebay for about 25 quid earlier this year, and have a 3 sim card (the huawei device is branded 3 anyway, but they don't lock them) with 20Gb/mo data for 15/mo but you can get cheaper contracts since you don't need that much data. I run it from 12v, pretty sure you could mount it on an electric weelchair..
Many places don't have them, but many people who do have access to them are unaware and don't understand the advantage. OP sounded like someone who thought the only option available was going to a hospital and rolling the dice on insurance. I'm trying to encourage people to learn about urgent care. It can handle a lot of common problems and the price is super predictable. Usually it's listed on the web site. (Come see us with a UTI? $125). It's worth learning about as an option. Google urgent care near you! It doesn't solve everyone's problem, but it solves a lot of people's -- and I want the industry to thrive and expand and hence bring down the cost of urgent medical care for everyone.

Absolutely you still need to get there. Absolutely Uber is a good option when you shouldn't be driving.

Don't take an ambulence unless getting medical care on the way could be lifesaving. Don't go to an ER unless getting medical care in the next couple hours could be lifesaving.
> > Key vs Secret

> An AWS_Access_Key is basically just a random username. If you understand how userids work in your system, you don't have to worry about this.

The big difference is actually that the aws secret key is never sent to the server, but rather used as the secret in an HMAC.

That means that if I make a request to S3 with a given secret key, S3 never has access to that secret key (rather it takes my HMAC'd signature, passes it on to the IAM service internally, and gets back a 'yes' or 'no' for if it's correct).

That means that S3's logs can't contain sensitive information (the HMAC includes a time, so it can't even be replayed after a short while), any networking dumping I do doens't contain the secret key, etc.

This is a useful property in general.
I think you meant HODL.

I agree that Google is evil regarding data collection. I have no illusions about Google. But I am dealing with it through blocking Google calling home mostly via DNS, firewall and some custom extensions in Chrome or using Firefox Focus and on the go via Raspberry Pi router and my private VPN.

Apple however is calling home no less then Google and is quite secretive about why and what information is transferred so I am blocking most of it same as Google.
Micropython also exists, and works pretty well across a variety of microcontrollers, this one included. The big thing it lost was good tracebacks, but it seems reasonably performant.

There are also lua implementations that run on a variety of microcontrollers.

Maybe give ~anything else~ one of those a try instead.
There are no hutongs in Shanghai. The guy is obviously an anti China shill spreadign lies with his 2 hour old shill account.

There are longtangs, but there are very few of them left. Most got torn down to make space, some were preserved and turned into tourist attractions like Tianzifang.
Awesome!! No advs!!
I hope you won’t stay complacent about the battery issue. I would have 70-80% left in your scenario. Is it possible that sweat was leaking into your pocket and keeping the screen active?
>> then you look at a Pixel 2 XL, that's about $200 cheaper than the iPhone X

And that's where the iPhone 8+ comes in.
I didn’t mean from Apple or an authorized reseller. Check Swappa - that’s where I got the above price.
Excuse me, I've seen many dead bodies in shanghai, lying out on the streets for everyone to see. One of the most memorable one is there was a guy laying face down lifeless, his legs covered in gangrene, about a block away from a busy metro station construction. He must have been there for days.
Is my 20 year old (clean) legal entity worth something in the US?
(US entity) in France (where I'm from), older clean companies (legal entities) are worth a bit of money: larger corporations buy it for tax optimizations purposes. Where can I find similar information for the US? I can't find it anywhere. Thanks!

I have been using a Xaiomi Mi4i for a couple of months and at the beginning it was great. The camera was awesome and it was worth the 200$ I paid for it. But after few months it became slow and the storage became a bottleneck. After that I've switch to an iPhone SE and never looked back. I've been using if for almost a year and it is smooth and perfect for my day-to-day work and not to mention it is worth every penny I've paid for it. I think I'm gonna stick with it for a couple of years.
Cleaning data eliminates the driving force to develop truly autonomous algorithms.
Ignoring false positives for a second, isn't this easily fooled by putting on a prosthetic nose or something? Or plastic surgery? Hollywood makeup is pretty good at drastically altering someone's appearance in a few hours at the most. I don't know why a motivated terrorist can't just change their appearance before bombing a plane.

Who is this really going to stop?
Don't work with closing prices for statistical analysis. Work with returns (really log returns). This would have simplified some of the code, and made the plots in the same units rather than requiring separate axes.

I use the count-it-as-a-rental for several items, not often seen as such, like cars and phones. Yet I still own an S3mini, so not exactly a trick to spend much ;)

Edit: oh and I just bought a 20 y.o. car. My way of seeing it is useful in this case because I add the (very high) assurance rate, repairs and gas to get a realistic price. I predicted a reasonable car life and compared it with the numbers for a brand new car.
As noted earlier, the names first and rest date from the 70s and were already around in Lisp Machine Lisp. Also, to nitpick: in Racket, first (car) will sometimes throw when used on lists, too, if the list happens to be the empty list (which has been true for decades in Scheme). It's more correct to say that it throws when used on non-pairs/conses (aka atoms).

He has no proof of that
I agree with what you are saying, but making visitors confused needs a bit more than just a misspelled domain name. People have brains... Ok, not all of them (brains) are so well developed, but I refuse to believe that landing on that website will fool anybody. Sometimes we try too much to be "fair" for the sake of being the "good guys" and we don't see things in context. Of course we don't know for sure that he will not try to sell anything or try to fool people that he's actually Google, but I'm only talking about the present. I don't think his act looks cool and I also don't think it's an evil act. And I don't even think his content is that good, but his content definitely doesn't try to fool anybody.

Anyway, because English is not my native language, it's a bit hard for me to explain why I don't think is fair to flag it up.
My semi-budget android phone has 1.5mb of L2 cache.
Sure thing bro, you seem to have unpleasant dreams.
I’m sure you got yours because you genuinely like the product. That doesn’t make the assertion that lots of people’s motivations for owning one because it’s a status symbol childish. And I’m sure those people would deny that’s the reason, too. Would lots of people admit that they bought BMWs to impress other people?

What I saw on launch were lots and lots of people Tweeting and posting about having placed orders and then posting pictures of the box. Forgive me, but that’s not something you do if you just bought the phone for utilitarian reasons.

Well, let's let the author try to convince you that NPS is a harmful, horrible number to summarize a company's performance on.

He would tell you that NPS is only like earnings or revenues if we allowed either to have 50% or more of their data filled with arbitrary numbers, not audited data collected from state-licensed specialists who would lose their job if it was discovered the data was manufactured whole cloth.

The author would also tell you that NPS is easily gamed and there's no checking on whether that is or not. He wrote extensively in the article the various techniques that folks can game the numbers. If this is a number reported to shareholders, shareholders should insist (No, Demand!) that the numbers be corroborated by a neutral third party that will accept liability for any errors. (No surety insurer will guarantee such a liability, for the risk of error or misrepresentation is way too high.)

As you stated, most use follow-up questions to get a richer understanding of the customer. What the author would tell you is that it's clear the NPS recommendation question taints those followup questions and diminishes their validity and inherent value. If the true goal is to learn a richer understanding of customer experience, there are many better ways to achieve it.

In other words, the author believes if executives want a simple metric that is better than NPS, a random number generator is the fastest and cheapest way to achieve it. Why bother with customers at all, if all you're going to do is squander your interaction with them on such a foolish metric.

— The author.
Everyone would... who could afford to. Now ask yourself what the majority who couldn’t afford it would do to protect and advantage their offspring. Gattaca is probably a fairly tale, and a nuclear wasteland the reality.
This is true of lots of API secret schemes that don't have an opaque random key ID.

If your secrets are opaque random tokens that only have meaning as an assertion to your servers, it's worth asking yourself what value you'd derive by trying to hide them from server components. And, obviously, something on the serverside will need enough information (almost always: the secret itself) to verify the message.
Ah, ok! Yes, I’ve bought five iPhones on Swappa and Gazelle. I don’t think a used or third party refurb is an apples-to-apples comparison with a new X, though I prefer the SE. I’m hoping the SE 2 in the spring will have iPhone 8 internals.
>It is a phone beset by compromises, the only thing it does reliably is broadcast that you are rich enough to buy a $1000 phone.

I think most of us with engineering backgrounds have a very hard time accepting that social capital is a valid reason to buy a device. It may just not be valid for me personally.

Who am I suppose to believe "analysts" or Apple who gave revenue estimates that if they met, would be a record breaking quarter for them?

By the time they gave those estimates, they were already about a month in the first calendar quarter.
An $800 graphics card has an immediate use case: high FPS for games at high resolutions and high settings. Which is very important in competitive gaming, for instance.

I don't see such a use case for a $1000 smartphone. What important task does it solve that a $300-400 phone doesn't? A slightly better camera, slightly smoother scrolling, slightly faster web page rendering. None of that impresses me in the slightest, these improvements are marginal.

The big difference relies on the fan, he will be able to pick which artist they give their monetary contribution to. Think about it like a big music festival in which at the entrance you receive an electronic wristband with some currency you have to spend. You go around checking out different shows, then you tap your wristband and decide how much you will give to each artist. It is a small difference but this will foster the creation of better music.
