It is quite hard to make a "Pro" machine targeted at professionals with a product line up of 4 laptop (and maybe 4 laptop total in the whole Mac line) with very little configuration options.

That's the most obvious conclusion of all those MBP review and comment. Apple just serve a small slice of the consumer market that intersect a narrow slice of the professional market. That narrow slice just gets smaller with each major iteration and Apple is not sad about it.
Which ones have you tried?

If you want to have something to talk about when people are talking about female authors and Austen inevitably comes up, I'd recommend Persuasion, and maybe Emma provided you are OK with imagining your own ending to make it the slow-motion soul-crushing tragedy it so clearly wanted to be.

Persuasion wasn't given her final punch-up editing pass before she died, and so it lacks much of the "gosh I, the author, am so clever and my remarks so cutting!" tone that I've been unable to get past in her other books (save Emma) while still actually being reasonably clever. It's also quite short. Emma is kind of a take-down of that exact tendency in Austen herself, so it worked OK for me.

Mind: if you're not OK with the prose, tone, and topics of 19th century English literature in general, you'll hate any of it regardless.

Anyway, it can be a good thing to get a taste of the "foreign" in reading.
For the past year or so I've been using the key sequence "fd", which I discovered from spacemacs. (I've actually copied a lot of spacemacs keybindings because I found them very ergonomic.)

After trying to build a healthy habit app for several years, we have found that the most effective way to do it is to turn what you're trying to do into a game. It doesn't need to use technology - you could just be doing it on a piece of paper.

There's an important psychological reason behind this. When we usually try to build a habit(or 'change a behavior'), we're going against our default nature. If that weren't the case, you'd already have acquired that habit.

Now going against your nature takes willpower. And research has established [1] that we have a limited amount (budget) of willpower everyday. Expend the budget on one thing, and you have no more of it for another. In experiments, people are more easily tempted by an unhealthy snack after a hard day, because they've already used up their willpower for the day. Bottomline: willpower based behavior change is very hard to sustain.

Also, we usually interpret our failings to keep up with our behavior change effort as guilt and failure, rather than the budget of willpower drying up, which is what it actually is. That starts a negative connotation with the very thing that was supposed to bring a positive change to our lives.

I don't want to sound promotional, but we're seeing incredible change in people's walking behavior by turning it into a fun engaging game/app [2]. It just seems to work where an 'endless willpower' driven approach fails.

The interesting insight into this process is that the healthy habit needs to be a side effect of this game. It cannot be the main focus of the game. In other words, there must be a strong gaming core loop that's just fun and sticky by itself, and which is what people think of when they think of the game. The core loop is basically going to be fed by (among other things) elements of your healthy habit.

That's really inspiring that you started your own business! I would love to hear more about what you do.

I'm dealing with some personal stuff and feel like I'm in the same boat, having to start my own business to have the flexible hours that I need. Any advice you can pass along would be appreciated.
That's fair. I was particularly referring to the 13", and more so referring to how the article specifically was in context of someone switching from an air to the pro. They all seem to have gone the route of thinner and sexier while sacrificing "proness," though.
>There are too few interesting full games available.

That's never stopped consoles from selling. Eventually, those games come out.
> It's not for authoring statistical papers (as the other comments stated

While you are technically right what will most likely happen is what we can already see (on https://bookdown.org/) - exactly what I described in my comment. Of course one could write a novel with it. Any publishing tool can be used to publish "just text". But who is going to end up using this tool? Pretty much only people already using R, and that - apart from people taking a course - is people doing statistics.

I looked at two randomly selected pages in two randomly selected books on the homepage (I swear I didn't click on more than those two to select examples that fit my narrative), both show it's being used just as I said.

My reply was aimed at someone who doesn't seem to know any of the background story.

I agree with you that it's a nice tool for a lot of purposes.
Ctrl-C is equivalent to pressing Esc in Vim and you don't have to move your hand so much.

OK. That's the super optimized way to read the encoded data. Makes sense if performance is important.

Writing is the harder part. I suppose you could just make 15 such tables, one for each possible value you could write.

"Just because you can, doesn't mean that you should."

I think people could be picked up and dropped off just fine prior to this update so it's not something fundamentally broken. Could things be improved? Sure but the benefits need to be weighed vs. the tradeoff.

Given the many responses that you have gotten so far arguing against your stance, it might be helpful to consider why people are having such a reaction. We have valid concerns and they should be addressed.
I made no claim about popularity. I did make a claim about productivity. Big difference.
I thought so too, but SHA-256 should apparently be susceptible to Grover's algorithm, which would make mining O(sqrt(N)) instead of O(N).

Of course, a practical quantum computer would also likely break public key cryptography, so you could just take other people's coins instead of doing all that tedious hashing.
This is the right answer, at least for visual dataflow. It should be done by diff/merge of graphs, displayed visually, not by converting it into a text-based format and using something like git, Perforce, or cvs. Dataflow can be expressed textually, but you'd have a hard time following the code.
Comments about inflammatory topics need to get more civil and substantive, not less, if you want to post them to HN. If you rant like this about a thorny social issue, you're just poisoning this place and setting it on fire. That's vandalism, regardless of the issue you're commenting on, and it's the opposite of what you ought to be doing if you're genuinely concerned about the substantial underlying problems.

Please don't create HN accounts to break the site guidelines with.

If what you need is a regular FDM machine our $3500 printer is a really, really fantastic one. It's the least hassle and has the best out of the box prints out of any desktop 3D printer I've used.

If you're looking to print aluminum replacement parts, you should look at the higher end machines. They have the ability to print continuous composites (our homegrown, weird, and very powerful 3D printing technology) which will let you print parts which are strength/stiffness competitive with Aluminum.

While our $69,000 printer definitely has an enterprise price-tag, it's still the cheapest (on an amortized cost basis) way of getting strong parts with a 24hr or less turnaround. The purpose of the laser scanner is to close the loop on what is typically an open-loop system in essentially all other 3D printers. I can't say too much more about this but we're adding a lot of cool features all the time.

(Obvious Disclaimer: I'm trying to sell you on the printers we make because I believe they are the best)
If there is a curse of our industry, it is almost willful ignorance of just how hard the physical engineering fields are.

The simple things with pipes are simple. Yes. However, to think we haven't made advances, or have no more to make, is borderline insulting to mechanical engineers and plumbers.

Ironically, deep learning will likely help lead to some of those advances.
I'm currently going through the advent of code challenges (http://adventofcode.com) with Clojure and watch a few talks (https://www.youtube.com/user/ClojureTV) next to it.

The cool thing about the challenges is that they are language agnostic so you can try whatever you're interested in (CL, Scheme, Racket, Clojure, …). A bit like Project Euler (https://projecteuler.net) but more fun.
You might want to do code formatting for that. Look at the help[0].

Running five miles before breakfast is more than just a habit; it is also a skill. Many people simply can't run 5 miles right now, they need to first train up to acquire the ability to do it.
Over 10 years old, but still the best modern Common Lisp book. It helps, that it has been written by someone who had a lot of experience with other languages (Java), so less captured in a Lisp ivory tower, showing a truly practical approach.

Highly recommended!
I'd suggest you read https://www.wired.com/2013/03/anonymous-phone-location-data/ if you have not previously seen this.

Part of the issue is that location has a lot more "physicality" tied to it. One can't easily change where they live, work etc. whereas it's much easier to switch credit cards.
I think you need a complete change in mindset, because you're just setting yourself up for failure.

You shouldn't need to develop a habit like reading or exercise. If you don't truly want to do these things then you'll stick to your systematic habit for a few days and it'll fizzle out, then it's back to the drawing board.

I've been walking/jogging a few miles a day for the last 5 years or so. Now it's part of my life because I straight up enjoy it. I also quit smoking cigarettes cold turkey after smoking a pack a day for a long time.

Both were honestly really easy to do because deep down I wanted to do them. I woke up one day and the room was spinning which is something I never encountered before. It scared the shit out of me, so I immediately changed my life style.

You should be asking yourself why you want to read and exercise more. Is it because of a long term goal? Good, write that goal down and stick to doing things that point you towards it. That's all there is to it.

If you find that too difficult, then your goal is not really something you care about, so think harder. Keep repeating that until you find what you really want.
It is a lot more than that. Calling conventions, register names and usage, etc. etc. I have a "cheatsheet" sitting on my desk that I wrote up last time I need to do some x86-64 reversing. Do no sit down with a x86-64 binary and use this manual as a guide, you will not get very far.
I really admire people who make stuff like this. It's completely ad free and open source too.
Stem cell research bust?
I've heard but I don't recall the source, that some new drugs they are working on have an effectiveness rate lower than the placebo effectiveness rate.

There's also the Placebo Paradox: it's unethical for a doctor to prescribe placebos, but it's also unethical for a doctor not to use a treatment that works.

Blew my mind!
That is factually false, as icebraining went through the tedium of demonstrating.

I guess this is theoretically possible (...maybe..), but I would definitely require cooperation from the underlying operating system and some of the hardware.

Additionally, processors have "modes". You tell the processor to go into 64-bit or 32-bit mode. I don't think quickly switching back and forth between those in real-time is a very good idea.
I've been working in JS full time for a couple of months now, except for a short break to build a JSX parser for Emacs. Switching to lisp was such a breath of fresh air. The code was denser, and every line took longer to write, so not sure about overall productivity, but man was it more enjoyable to write!

I wish there were an update to this book. I seriously looked into giving up on JS and using Parenscript and Wookie or Hunchentoont but it seemed like I'd be taking on a lot of yak hair. Does anyone here use any lisp for Web Development? What's the modern lisp (CL or otherwise) stack?
It is actually much easier to apply a random forest (or really gradient boosted decision tree, which almost strictly dominates random forests) than a linear regression. Decision tree methods require far less data preprocessing than linear regression, because the model is able to infer feature relationships. Obviously if your features are linearly related to your target than linear regression is much more viable.

If you have time, would you like to discuss some of these ideas?
Simple regression has a lot going for it beyond simply being a simpler model. For example, it produces models that are easy to interpret. That is an enormous advantage if you're looking to use data science to help drive strategic decisionmaking.

My personal suspicion is, in a market full of people who are using ever more sophisticated algorithms to ratchet up their customer conversion classifiers' F1 scores by .001 per iteration, the leader will be the company who's decided to steer clear of that quagmire and spend their time and money on identifying new business opportunities instead.
Lighting takes very little power once you switch to LEDs. I replaced all the bulbs in my house a couple of years back, and the total draw - were we to turn all interior and exterior lights on at once - would come in at around 250 watts. This is effectively negligible - the refrigerator alone uses at least twice that much.

In any case, the real answer is not solar by itself, but solar plus other sustainable sources like wind and hydro.

Thanks.

"Challenged" (not debunked) would more precisely describe what the linked article says. I'm not saying the claims were set in stone, but even intuitively, it seems to make sense that people might be tempted to 'throw in the towel' after a hard day.

As for me, I've found I'm usually actively seeking out a guilty pleasure after a hard day. A cookie (or a beer) looks pretty appealing at that point.
Depending on the program, possibly. But a PhD is not required to learn nor work in machine learning.
If I have understood this correctly and the placebo effect is so strong then maybe more research should go towards hypnosis, self hypnosis for treatment without drugs. After all if a state of mind can cure a disease then that state of mind itself is a valid cure if it can be replicated

I _love_ Bookdown, but only once I figured out how to incorporate it into my writing workflow.

I'm writing a ~150 page monograph. As the document evolved, organizing the prose and reordering the structure gradually became too cumbersome in plain text Markdown files (whether I used R Studio or some other editor). So I shifted my writing over to Scrivener---the best long-form writing tool I've ever used, highly recommended.

I write RMarkdown in Scrivener and compile the document into plain text. I manage my reference materials Zotero and export bibtex bibliography. Bookdown then takes the two files, incorporates all my calculations, tables, plots, and figures, and outputs a beautifully rendered document.
Thanks for clarifying! I'm from Norway and "gransk" is the imperative form of "investigate" in Norwegian.

What you said is true. Banks can always lower their transaction costs as they see fit(competitions) and beat BTC transaction fee anytime. So transaction cost might not be an advantage in such situation.

But people might still use BTC and pay up that extra cost because of its special property: true ownership.

Isn't it the case that if the strong placebo response is preventing us from determining with confidence that a drug works, the problem is with our calculation of confidence and not the placebo effect? Placebo responders should be equally represented in the test and control groups, so their effect should be able to be measured. Our calculation for confidence just needs to take them into account; we already know that our measure of stastical significance is flawed anyway, we need better statistical models.

Ah it's just an expression, basically meaning "everything you need included." In the context of web frameworks, "batteries" are typically things like:

- An HTML templating language for your views

- An Object Relationship Mapper ("ORM" - makes talking to databases consistent, and automatically populates your models with data from the database)

- User Authentication/Session Management

- An Admin GUI for managing your database models ("CRUD" Actions - Create, Read, Update, Delete)

Tenured at Princeton, had already solved some fairly big problems in the field, and it helped that FLT had recently been "reduced" to proving a conjecture about elliptic curves which were already very much in Wiles's wheelhouse.

Not to take away from his achievement, but I think it is not stressed enough how much the proof depends on work from previous decades that a priori had nothing to do with Fermat.
Who says you have to maintain old code? We're talking about simply not deleting it and establishing a discrete semantic for the new version as truthfully, a new version is new content which demands a new name to accurately and precisely describe it. If it didn't it would be like saying different content doesn't produce a different hash.
I think this fundamentally misses an important part of human nature -- we can want things in the abstract (be more healthy, be more well-read, etc.) but not actually "straight up enjoy" them.

There are techniques for training yourself to think differently about tasks though; Tony Robbins talks a lot about how to train yourself to have the positive associations that you choose, instead of the ones that your environment and upbringing bestowed on you[1]. Some of that reads a bit cultish but I think there's some good stuff in there.
