> The logic-variant of Null usage for "unknown" "missing" "invalid" values is unavoidable in programming.

On the contrary it’s perfectly avoidable.
You just need to use an option type with a language that supports comprehensive pattern matching and won’t even compile if you don’t explicitly consider the case of a missing value.
If your model is flawed and you don’t want to explicitly specify that some value is optional then the problem is in your way of thinking.
And there is no need to invent a language that doesn’t support nulls, they already exist.
c# has an option type. You can make any struct type nullable with a ?.
Half of the worlds greenhouse gases? The agri-culture industry has to suffer as a scape-goat for the car and power industry. I m so sick of this pseudo religion/blame industry that has sprung up around agri-culture.

No matter what they say, this carbon emissioned was in the cycle and once diggested by humans and returned to the fields, gets back into the cycle. Do not look at total emission-numbers but new-emission numbers.

The only place where there are new-emissions, if you burn down rain-forrest to herd cattle or create synthetic fertilizer.

If hitler where alive and the holocaust debatted,
he would have some third "neutral" press agency post statistics today, that in the overall history of jewish death reasons, national-socialism is a absolute minor cause compared to cancer, car-accidents - and voila debate shift archieved.

Again this should be fineable to a point, where its for big companys no longer interesting to have the public misled.

PS: Overall good for the planet would be if cattle farming ceased entirely and beef would be replaced by synthetic proteien.
Well any representative that votes No puts themselves fair and square in the parliament of whores.
If you lack either the intellectual honesty to admit that one of the few reasons people pay for things in Bitcoin is to evade local regulations or the intellectual capacity to grasp the linkage between avoiding regulations and avoiding taxes and quotas on carbon, you probably shouldn't be evangelising about "fairer financial systems"...
Thanks for posting the video, OP. It was really interesting. Shame it didn't get very many comments.
> I don't think you understand what literally means.

Is that better? I know the meaning and used the word appropriately. I just left out a few other words because I thought my intent would be clear.

But you know, it's trendy to complain about "literally" now so have at it.
You're literally that guy. :D https://xkcd.com/725/
No, that implies companies have the same rights as individual people. They do not and should not as they don’t have the same legal constraints as people. There’s no human equivalent to many of the abilities enjoyed by corporations and corporations don’t die and cannot be imprisoned. They’re also able to raise funds in ways humans may not. The list goes on from there.

I was careful to not use words related to pain, because whenever you mention that people are quick to claim that fish don't feel pain. Probably because so many people catch & release.

Which do we think is more likely?

a) Choosing to eat too much junk food causes hormone imbalances that increase the chance of infertility;

b) Hormone imbalances that increase the risk of infertility in women also tend to increase one's appetite for junk (AKA high-energy) foods.

Having witnessed these problems up close, I'm going with (b).

FWIW the actual substance of the article is this paragraph:

Roughly 1 in 10 women of childbearing age have difficulty getting pregnant. Most of the time, it’s caused by problems with ovulation, often related to a hormone imbalance known as polycystic ovarian syndrome (PCOS). Some signs that a woman is not ovulating normally include irregular or absent menstrual periods.

PCOS and other fertility-related hormonal issues are much more complex and deeply rooted than food choices, though they're not unrelated.

The real issue is inflammation and auto-immunity, in which food intake is a factor but only one piece of the puzzle.
Only NIMBYs are trying to control other people's backyards. YIMBYs can't do anything to your backyard, because you own it and can make any choices about your property for yourself. But you don't own your neighbor's backyard any more than some schmuck who lives hundreds of miles away does.

Perhaps you had the impression that your title and deed gave you property rights over your neighbor's yard merely because you live in the same neighborhood. If so, you were mistaken.
I was feeling exhausted recently, in desperate need of a vacation. I took an 18 hour trip to Chicago to visit a friend of mine and came back quite renewed.

In a perfect world I would probably only socialize once a week, with a good friend each time.

I really should make that a higher priority, even if some travel is required.

There's really no substitute for a real friend.

What’s wrong with multiple tabs in a browser?
Yeah, I've heard those arguments before and I find them pretty specious. We humans are always super quick to claim that it's ok to do <thing that inflicts pain> on <thing that we want to do it to> because <some reason that thing doesn't actually feel pain anyway>. It's been applied to fish, human infants, black people, and all manner of other creatures that someone wants to inflict something nasty upon.

You don’t even need fancy static type checkers to avoid this. You literally just have to not have a null and not allow initialization of variables without values. It is more work to add null to your language than to not have null.
It's weird to think that a couple of years ago I too was using the facebook app. Since then, I've deleted the app, then deleted my account, switched from stock android to LineageOS.

Now I can't fathom how I accepted to carry that crap around with me, and sometimes forget that just because I don't use it, social media hasn't vanished from the world. I feel as if I was living in a post-social media era, because in my subconscious, social media is dead.

Ironically you can make nullsafe methods in Go

type X struct{}

func (x *X) y() {}

func main() {
var x *X = nil
x.y() // no error
}

Also its not unsafe. Go doesn't allow unsafe memory access unless you use the unsafe package.

It is incorrect though. An Go does allow you to write bugs.
Null is dangerously wrong.
Languages that avoid it give a much nicer experience because you explicitly write your model considering which values can be missing.
They use the term “data store” multiple times, not to mention:

> and features like persistence, replication and pub-sub.

(Customer testimonial)
> We have used Redis on everything from storing asynchronous task queues for tens of thousands of CPUs to a centralized persisted key-value pair store for the feature vectors output by our ML models

Additionally, “persistence” isn’t mentioned at all in the “Coming soon to Cloud Memorystore” section.

I’m not trying to be a pedant, I just think it’s dangerous that it’s not made abundantly clear that there is no persistence.

It's just another name for Null in practice. Or a "typed null" to be more precise. It's got some nice properties, but really it's the good old tri-state.

As the op says - is a "logic-variant of Null"
I remember reading this article in Scientific American at the time. It seemed like it had a lot of things right even then, although it also seemed to contain some hopelessly off base ideas as well. One of the interesting big but close misses here is the idea of "tabs". You see this in the Star Trek: The Next Generation (and related) TV series as well from the same time frame. This idea that ubiquitous computing would mean that we would have lots of computing devices that each were not very sophisticated. The reality is that it's actually shockingly easy to make very capable computing devices (e.g. smartphones, tablets, etc.) and for the most part you only need one of each variant (e.g. an ebook optimized one, a tablet, a smartphone, etc.) instead of many.

Also note the sharp contrast between the concept of "scrap computers" that have no identity whatsoever and the reality of today where everyone's mobile computers (phones, tablets, e-readers, laptops, etc.) are all intensely personalized. A lot of these errors are based on trying to naively map pre-digital behaviors and use cases onto a world of ubiquitous computing, rather than imagining entirely new methods of interaction and use. Why bother duplicating hardware to maintain two separate pieces of information locally when you can simply have two files open in different tabs in an editor, or two google docs, or emails, or what-have-you?
We really try to avoid being a "bleeding edge" distro, and prefer to focus on leading edge. We don't always do every thing absolutely before anyone else; we try to be the first to provide integrated, tested, usable versions of innovative open source.
Dude, let it go already.
And that having everything being 'implicitly nullable' is a categorically worse for maintainability, readability and comprehensibility than using explicit Option<T> types at the boundaries; such as the implementation in F# [1], with an expressive matching syntax.

It is now common when creating a library to rely on manual checking and coders explicitly writing code to check and throw NullArgument exceptions for each object parameter in every public method, and then writing dozens or hundreds more pointless unit tests to ensure this null exception behaviour works as expected; this is totally unnecessary in languages that demand explicitly stated Option<T> when an Option is meaningful.

Instead of requiring all the above for safety -an approach which will notably fail to report any errors if the null argument checks are partially or completely omitted- we have -and we should prefer- languages where the compiler or interpreter will not let us pass null into a function where null makes no sense, because that fact is encoded in the function definition.

At the library boundaries, which are comparatively rare to internal code, we can simply use the explicit Option type.

I should note I have one objeciton with the F# implementation - in that I think that ideally the properties { .IsSome, .IsNone, .Value } should not exist, as they promote bad programming practices.

And, where I'm from (Cambridge, UK), they also:

Are more expensive than driving.

Are regulated in such a way that prevents a competitive market.

Are run by profit making companies that demand subsidies from government.

Don't run at night.

Are full at rush hour.

Spend ages at the bus stop while everyone buys tickets, argues with the driver, asks which bus this is etc etc.

A single ticket can't be used on buses from two different companies.

I cycle. The buses seem like a threat to my safety because they are too big to overtake safely on a busy street. Also their engines are at the back, so I can't hear when they're sneaking up behind me.

Once they don't need a driver and are electric, most of these problems could be solved. I'll re-assess then.
One of Racket’s is explicit design goals is to be a toolkit for designing and implementing new languages, so I would say it is the better choice.
It's real money being saved. I've been involved in such efforts at four companies now, and in every case the savings have been very significant.

The claim you should be suspicious of is the one that says you can save money migrating to bare metal. That may be possible in some cases, but not in any typical large company.
Not true - lots of cities have bus lanes that can only be used by buses. Depending on traffic congestion, at times it could well be quicker to take the bus.

> The paper doesn't say that market rate development has a negative effect on displacement at the local level.

Again, simply incorrect and a miscomprehension of the study:

"These two block groups illustrate the complex relationships between housing development and demographic change. While both neighborhoods have witnessed dramatic development in one of the fastest growing parts of San Francisco, and have similarly seen significant growth in housing prices, one may be classified as experiencing displacement of low-income households, while the other does not." [emphasis mine]

(The one that didn't maintains "high rates of crime and concentrated poverty which may be dampening the attractiveness of the neighborhood" and the majority of units are rent controlled.)

If you can save money by moving to AWS at its publicly listed prices, your company has absolutely mismanaged its IT infrastructure.

You can do 10x cheaper than AWS easily, if you are willing tomake tradeoffs that AWS just can't make globally for all their customers.

EDIT: If you’re paying silicon valley wages, and target a global audience with your site/product, and can get from AWS something cheaper than the publicly listed prices, then AWS very likely will be a good deal for you. But many companies have different needs than these, and may be able to save money by dropping things they don’t need.
F# language and tools update for Visual Studio 2017 version 15.7
Couldn't agree more but I think some people need a prescribed system, because they find it hard to listen to their own intuition. Following your intuition is optimal however, because we're all different.

I want to add one point, which is related to your final points: we all need to move regularly for health. Getting up and running up and down the stairs, round the block, or round the room is essential. It actually improves concentration too. Unlike conversational interruptions, intermittant bursts of exercise don't make you forget where you where, instead they help prevent tunnel-vision and allow your mind to zoom-out briefly to ensure you're going in the right overall direction.
Great site, seems to have a good collection of lisp resources. I am waiting for the documentation to go online, it says it is still parsing the TeX sources of the commonlisp hyperspec.

As a side note, I downloaded the Lispworks Common Lisp Hyperspec, but I could only find the HTML version.

I see that the project is on Github, maybe someone will parse the Hyperspec and generate the documentation pages.

I am adding a reminder to my org-agenda for next month, maybe I will attempt to do it :).
