> Disclosure: I am short a company (not mentioned in this article) that hypes its ‘blockchain’ solutions. Short AMD. Long FB and GOOGL.

Is the author short Riot Blockchain? Because that's an easy one to short. Maybe Long Blockchain Corp? Kodak?
This isn't meant to be snarky, but maybe this post just isn't for you, in the same way that posts about Ruby on Rails simply aren't for me.

On the other hand, if you use Python, you should definitely check out Jupyter notebooks (formerly IPython notebooks, and now JupyterLab, I guess). They're useful when prototyping data pipelines, since the state of the interpreter is saved, letting you iterate on ideas and see the outputs quickly.
Or for that matter self driving cars. You could commute for 5 hours a day, spend 2 hours in the office and go home again. All while being productive. That greatly increases the commutable range. Then you have the prospect of self driving Motor homes, moving with the work becomes that much easier.
And also so that the power required for the display may be redirected to the more critical timekeeping function if necessary. If you only have enough power left to keep time for the next month or to power the display for the next day, you turn the display off and hope that more power is added to the system during that month.
> A company’s stance on blockchain can also serve as a test of a company’s management. In my view, companies pushing blockchain technology (e.g. IBM, Microsoft, Intel, Oracle) are disconnected from customers’ actual needs and have mediocre management. Companies that don’t talk about blockchain (e.g. Facebook, Amazon, Google, Apple) are more likely to produce sensible technology that will work in the real world.

And yet, IBM, Microsoft, Oracle, and Intel are solving their customers’ needs on a daily basis. Could it be that blockchain tech is in its infancy like the Altair was at Xerox PARC?

I’m not sure what repulsed me more: the author’s smug attitude, or the trash design of his blog riddled with ads.

You're assuming that accidents are equally likely with and without helmets and ignoring OP's point that, on balance, you're better off biking without a helmet than not biking at all.

You might actually be right here. I do not know. Either way, don't expect "I really don't need to cite anything" to convince anybody serious.
Hi,

Course author here. Thanks a lot for posting this (and for signing up).

But, it's worth noting that if you buy the course on my platform at https://buildasaasappwithflask.com/ there are additional perks you won't get on Udemy.

For example I'm in the process of adding a new bonus section to the course that goes over building RESTful APIs with Flask. I've already released the source code and 1 video for it on my own platform but this will never make its way over to Udemy.

I'm going to be adding some front-end related bonuses too (only on my platform). Plus you get better support and I'm even thinking about doing things like recorded office hours.

If you don't want the bonuses / updates and only care about the cheapest price possible, please use my Udemy link[0] below for $10.99 because otherwise Udemy takes 50%. I don't want to sound like a complainer, but yeah, it took me 4 months of real life time and years of experience to create this course. I can't afford to keep making courses on Udemy when I see $3-5 per sale.

It's also worth mentioning those Udemy "discount tricks" are out of my control. I can set the price to anything within reason, but ultimately Udemy pushes courses out for $11 all the time. It's partly why I'm looking to remove all of my content from there in the future, but building my own audience is a long process. :)

In either case, any support is much appreciated. Thank you in advance for anyone who signs up.

Ask HN: Is it just me or is Google Cloud really expensive?
I'm a web dev that builds/runs/prototypes a lot of websites. I have 10-20 running at any given time. They don't receive much traffic, but they all have their own DB, storage, domain, etc.

I'm currently paying $50/mo for a VPS and it's working great.

I was considering switching to Google Cloud to save some money, also get some extra flexibility (can spin up different operating systems, scale as needed, etc).

But I tried spinning up a "small" instance (which costs about $15/month) and it couldn't run nginx + node server without CPU spiking 150% and timing out. I had to upgrade to the standard instance which is about $25/mo to be able to run it without CPU spikes.

Is there anyway to move my current setup to Google cloud in a cost effective way?
> Blockchain's primary utility is in creating what initially was a complicated way to allow people to convert money into another currency...

Blockchain's primary utility has nothing to do with money. An attempted alternative to fiat currency is just an easy, obvious application of the distributed ledger/consensus capability that a blockchain offers.

This myopic focus on "blockchain == cryptocurrency" misses so much of the point, it would be laughable — if it weren't tragic.
Could you please tell me how amazing Facebook's big data will help to deal with Comcast and butchered net neutrality, for-profit prisons, incredibly criminalized society, insurance/out of network healthcare prices and a gig economy slowly taking the job market over?
I'm in that boat. I think a technical bachelor's plus work experience and self-study allows me to get along, but similarly to mr_overalls in the sibling comment I'm going back to school for a master's degree. It seems that getting into a data science career can be done without at least a master's but it seems that it would be hard to advance without one.
I think this is an important point. Having worked in / proximate to public policy kinds of problems, Bayesian methods have some really great properties:

1. easier interpretation of results than frequentist methods for lay people (business strata, elected officials, or other decision makers)

2. Uncertainty can be quantified and visualized reasonably well, which helps decision makers not think of stats as a magic box that produces a single answer.

3. Sensitivity analysis can be placed right up front: selection of priors representative of the beliefs of differing opinions / ideologies can inform decision makers of when they should consider changing their minds, and when they might still hold out.

Downsides of Bayesian methods:

1) Conceptually more involved than typical maximum likelihood estimation methods

2) Computationally expensive

3) Methods might not be as well known to a nominally stats-savvy audience.
How so? Are you suggesting that the guys at the top are going to suddenly start caring about these things because there is a standards body that their employees belong to which says so? Or are you saying that the employees are going to refuse to do things that contradict code maintained by the standards body? Or are you saying that employers will care that a software developer doesn't belong to a standards body and won't hire those that aren't?
IPFS: the missing link for our future

Pardon my skepticism, but the whole "supplement" industry seems incredibly bogus.

Yes, there might be some benefits from little tweaks to our nutritional profile. But is this a priority compared to the massive benefits one gets from simply cutting out refined sugar, refined carbs, and other junk foods, and doing moderate exercise?

The idea of a supplement tailored to the individual seems to

a) vastly overestimate what we know about the body

b) be suspiciously aligned to marketing. It's easy to flatter people by saying they are unique individuals and need specialized tests and an expensive, specialized program to be healthy. Like, that the reason why you're unhealthy is because you've got this blood type and you can't eat beets on Tuesdays but you can correct it with this expensive supplement. And it doesn't have to do with your entire lifestyle.

The article just seems to be willfully ignorant. Blockchain has already proven itself useful to the millions of people who have bought things off of darknet markets. He tries to make the argument that the ability to fork the protocol is essentially the same as having a centralized third party control the protocol which is just astoundingly wrong.

He basically completely ignores the idea of a blockchain as a way for non-trusting parties to quickly and easily agree on truth but then makes the argument that since the smart tech companies AMZN, FB, and GOOG aren't offering blockchain services, that the technology must not actually have any real use cases, another ridiculous point.
My view on this is that it doesn't just work for "http page preloads assets to get", and more like "http request preloads other http requests" ... the difference is, in the case of a CDN, they could basically download a JS file for, say, a JS framework, but also send you jQuery, etc because they know it's dependent.

All this is to get away from a lot of our current hacky workflows (like file concatenation).
Speaking as a sometime ultra endurance participant I have to say this is misleading. Bone density loss only significantly affects those who practically live on their bikes, such as professional road racers. And even then it is easily attenuated by visiting the gym.
I would suspect that "$PEOPLE without helmets triple their chance of death by head injury". I also suspect that there are more car drivers with head injuries than cyclists, because there are much more car drivers to begin with. Should you wear a helmet in a car? Should you wear a helmet as a pedestrian?

After five minutes of googling, I sadly did not find any relevant statistics.
Where did I claim that? I think using Facebook's data for social studies is a stupid idea. Again that has nothing to do with the OP's post.
> There are a lot of SaaS markets where the customer needs high touch but can only pay low touch prices. That's not a fun place to live, though it can be a good place to start and then move upmarket.

This just seems like a really bad place to start. Do you have an example where it worked?
Also not to be missed, "The Origin of Spacewar" by J. M. Graetz (Creative Computing, Aug 1981), recounting from an inside perspective how the original MIT Spacewar! was born.

http://www.masswerk.at/spacewar/SpacewarOrigin.html

Martin Graetz was also reading a short paper on Spacewar! at the first DECUS (Digital Equipment Computer Users Society) conference in summer 1962, "Spacewar! – Real-Time Capabilities of the PDP-1": http://www.masswerk.at/spacewar/decus1962/
Not really. Satoshi's whitepaper pretty clearly lays out the problems that Bitcoin was attempting to solve.
Our work is based on government funded research as well, but it's more up-to-date.

Dangerous advice. From the article: "if a VC sends a follow-up email asking factual questions, they’re already emotionally uninterested. Many entrepreneurs get caught up in this process: they send the VC a fact and citation, which the VC nitpicks, etc., but it’s already too late. The entrepreneur has failed by not creating the type of confidence necessary to de-risk the investment."

If you want investors that actually understand what you do generally, or even better yet understand what you do on a technical level, this is terrible advice to follow. Investors literally become co-owners of your company, and there is no easy way to get rid of them. Raising from the right people slowly is better than raising from just anyone fast. It's a positive sign when investors actually dig in with real substantive questions after thinking things over, and an indication of how thoughtful they'll be as co-owners.
The article doesn't seem to confuse them. It literally explains the approaches used on the models they covered.
I would say... Monads are a concept that are useful when you are programing with monoids.

Do not bother trying to understand monads if you don't already have a good understanding of monoids.

Starting with monads is like trying to learn to divide before you learn to count.

In browser circles, 'chrome' refers to the bits of the browser UI that aren't the renderer.

It's hard for me to believe that Chrome's name didn't just originate from Google talking about taking WebKit and building their own chrome around it.

Design+Code is a pretty well-known course for designers that want to build iOS apps. The previous version of this course was a one-time payment of $50. For the newest version he's moved to a subscription with a 7-day free trial. However, you do have to add a credit card for the trial.

Ask HN: How to come back as a dev?
Hi,

I was developer for some years (mostly on backend). Then I moved to a job in a big corp which is more on product / project management but... I'm clearly not happy with the job (and the company is not happy with my work). After some years trying to be better in my job, I have really hard time to go at work everyday. (Sorry for the lack of precision, trying to stay anonymous). I'm around 35 (but started late to work).
I'm thinking to go back to the dev side but I feel totally lost on how to move.

I tested some CS/new dev language/other related skill through MOOCs/teaching website, but it's: too easy and I just feel bored after an hour (a loop / if statement is the same no matter the language) or a bit too complex and I lack the energy to make progress after a whole day of work.

I tested to work on personal project but I had a similar result: small stuff are easy but useless/boring (oh another todolist app), complex stuff are way too bigger for a wannabe-comeback-dev.
And on the top of it you add the time lost to try to install/configure things correctly (i'm really not the devops/hack another tool in 5 minutes kind).

Any advice?
Yes this exists, for example Travis-CI Pro has a free trial that includes 100 builds and is not time based.

It’s more than that; there isn’t enough critical thinking.

How many things are read and more-or-less believed without so much as a follow-up question? We don’t even ask who the experts are anymore, as opinion becomes fact. There is little thought put into statistics (just because 2 or 3 people are saying X in unison, is that really representative of anything as far as how many people think X?).

For completeness sake, here is best argument I've found against the idea of "Earning to Give":

Google has one of the strongest brands in the world. NYT's language is not that different from that used by ordinary people.
I think 'it's great' is quite an overstatement. For example, there's a bike lane all the way down 2nd Ave from the 59th Street bridge, but it's largely ignored by cars and parked trucks.

To the degree that it might make cyclists feel confident and less hyper-vigilant b/c there are lines on the pavement, I think it's actually more dangerous than no bike lane.
The people that don't show up to the gym are what make the business profitable.
> Given the difference between "existential risk" and "profitable enterprise" is a 5% change in churn rate, these customers may make all the difference!

That's exactly how it works.

> How does a company balance reducing churn with ensuring that customers who (perhaps temporarily) have dis-engaged can easily turn off the software?

The ideal model in my opinion (but that one is obviously not going to maximize profits/revenues) is to stop billing if the customer has not used the product in 30 days.

That way there is a balance between payment and performance, maybe at some point we'll see laws to enforce such a setup.

Yep, you should definitely host your own server. And build your own Linux distro. And your own computer. Then weave your own cloth, sew your own clothes, cobble your own shoes. Build a car. Buy some land. Build a house. Move to the country. Raise chickens. Till and sow land. Get off the grid. Abandon the modern world.

It's perfectly possible to drive a car without building one, or to become technically proficient without hosting your own server. If you DIY something, you may learn a lot about it, but it won't make you any better at the thing you actually wanted to do with it.
Yeah, the distribution of elements is weird and wonky because it depends on a lot of details about nuclear physics. First off, nuclei with odd number of protons or neutrons are less stable than nuclei with even numbers. That is what causes the staggered bumps every-other element.

The low-mass region is largely determined by stellar nucleosynthesis. After helium, largely works by shoving more helium atoms on. So, to you get lots of Carbon-12 and Oxygen-16, which are kind of like 3 or 4 helium nuclei stuck together.

The heavier regions get really weird, because those depend on the r-process. Some astrophysical events spit out heaps and loads of neutrons, which stick to nuclei. You go way the heck away from stability, then beta-decay back once things calm down. What products you get depend on the reaction rates of hundreds of possible reactions, few of which can be experimentally measured in a lab, because there is no way to make that strong of a neutron source.

Explaining that distribution is a topic of many, many dissertations, and does not in any way reduce down to a simple law.

I think Rails would be an excellent choice here. Lots of Gems and community and enterprise support. A lot of bigwigs use Rails for their production services.

Admin panel, tagging, search, you have gems for practically any functionality you might need.

To be fair, many of these people are actually disabled. It's just that previously they could work. Like the article says, their managers cared about them and and had the capacity to let them take lower-impact positions that they were capable of doing.

We don't appreciate how difficult it can be to employ these marginally capable workers. Keeping these people on staff at a small company raises health and operational insurance costs pretty dramatically, so it can be hard to justify keeping them on staff, even if you wanted to.

Disability is also pretty difficult to get, despite how the news makes it out to be easy. My father had multiple heart attacks and cancer, and he's still fighting to get on disability. And when he does, it will take years to come into full-effect.
Thanks! That's one's probably a bit long for my courses, which are 5-24 hours in length.
