>I wouldn’t worry too much until there is an actual use case, and if there is a use case, then why worry?

I don't usually worry much about over-hyped technologies that gets the executive types all fuzzy inside while the rest of us look from afar wondering if they even understand what they're talking about. Web 2.0, NoSQL, IoT, Blockchain... The list is long. And it's not all trash, there's often some value at the core of the hype once you remove all the fluff.

But Blockchain is a bit more nefarious that this IMO, because it goes hand in hand with cryptocurrencies. The huge valuation of cryptocurrencies is the only reason Blockchains got so much publicity in the first place. I'm certain that if Bitcoin hadn't recovered from it's huge crash a couple of years ago you wouldn't see nearly as much Blockchain this and Blockchain that everywhere.

Conversely if you look at cryptocurrency enthusiast forums they use these news articles about big companies investing money and resources into "the blockchain" as proof that there's some high intrinsic value to the technology and to justify a very high valuation and pump it even more, especially to newcomers. "IBM is going to create a blockchain, BUY BUY BUY!"

It results in a big spiral of hype enabling scams enabling hype enabling scams... Meanwhile as far as I can see the only practical use cases of cryptocurrencies and even "the blockchain" at large is unbridled speculation, pyramid schemes and buying illegal stuff online. All that while expanding a ridiculous amount of energy mining the damn thing.

> You hold a 5 percent fixed-rate 30-year mortgage

Wait, are you Americans paying 5% interest on mortgage, whitout even counting insurance? For real?!

Edit: Having looked at other comments in this thread, it looks like interest are taxe-deductible, which makes it more affordable, but that's also really weird: it means the gouvernment subsidizes financial institutions to charge American consumers a lot more than the normal prize …

Rereading it, you may be right. I read “what was parsed” as “as parsed by the json parser”, but chances are the OP meant “by the application layer”.

I didnkt read it that way because I don’t see that often in my job. Programs there typically know just enough about the format to do their job, and that job doesn’t include “watch out for external threats” (and they don’t all just use some common library that _does_ know the ins and outs of the format because they’re written in different languages. Also, we don’t generate libraries for each language (as would be common if the format were XML) because the json culture doesn’t think json schema is a good idea)
One common reason is to provide a flexible table for things that may not have an identical schema. For instance, an event log might have details about each event that differ based on the event type.

The core of haskell is relatively straightforward, believe it or not -- it's just that a lot of what is blogged about is bleedong edge, either language-wise or in concepts they explain.

PureScript is pretty much haskell, it simply compiles to javascript -- wouldn't say there is much skill transferability in terms of language when coming from js, but it might make sense if you develop front-end.

Don't know about the other languages.
I think the reason JSON doesn't take well to strong typing is that it is designed for Javascript. When you pass some Javascript object to the JSON encoder how is it supposed to decide which numeric representation to use? Does it always go for the smallest one that works? The Javascript decoder at the other end is just going to throw away that type information anyway, so all it is good for is verifying the data while you are parsing it. Maybe not a totally useless thing to do but it's a lot of work to get that modest benefit.

Actually there a few unrelated Object Pascal languages, the language features from Turbo Pascal, introduced on version 5.5 for MS-DOS, were copied from Apple's Object Pascal.

Then there is FreePascal with its compatibility modes and own extensions.

The object keyword is still accepted in Delphi, even if they don't recommend it any longer.

Also a few languages implicitly deference pointers as references, depending on the context.

A house built today of a certain size can be purchased with a lower monthly payment than it can be rented, yes, for exactly the reason you describe.

A house built ten years ago, or twenty years ago, or thirty years ago, can often be rented much more cheaply than a house built today can be purchased.

An apartment of the same size as that hypothetical house might be higher or lower, since the economics of apartment buildings tend to be different.

A 1-bedroom or 2-bedroom apartment can quite often be rented more cheaply than a 3-bedroom house.

"owning is cheaper than renting" is exactly the sort of generalization that gets people into trouble. Every situation is slightly different.

I do recall that in the two Finnish places I bought my offer also had a penalty clause - if I pulled out for any reason other than "failure to find financing" I had to pay €6,000 or so.

> He is the person who ruined cycling for the rest of the world. Tour de France no longer holds the respect that it used it.

One could have said that about the 1998 tour de France and the massive doping scandal. What Armstrong did was popularize road cycling in the early to mid 2000s for the American domestic market. Most of the benefit ultimately went to bike manufacturers and accessory sales. Look at the growth in sales for Trek (inextricably linked with Armstrong during this period, and LA is a trek shareholder).

I don't think it it considerably more or less popular in Western Europe than it has ever been. Nuat about the same.

Two things this also ignores that for me work out in favor of renting right now (in Seattle).

1) The options for renting and owning are not the same. We have a ~1300ft apartment that is just a bit too big for us; it is on the 4th floor and has an expansive view and southern exposure, which is rather important for me. There's transit access and groceries/coffee/etc. walking distance.
Condos in Seattle are few, esp. in new buildings. Most of the houses are far from stuff, are by definition on street level so even under ideal conditions few have lots of air and view, and vast majority are too big...
So, I'm going to be paying extra for sqft we won't use (we already have unused, unfurnished corners in 1300sqft), the yard that for me is a net negative (maintenance), and loss of quality in other dimensions (relatively worse view and light).
If my apartment was a condo, I'd seriously consider buying it. As is, it's hard to find a house that is not much more expensive than rent while ALSO being worse.

2) I haven't done the math for this, but in the end, you die. I don't care how much I'm worth when I die as long as it's >= 0. So, leaving aside the case of getting lucky with well-above-inflation appreciation (still, did houses in Bay Area appreciate that much faster than stock market since 2000 or 2009?)... one could sell the house in Seattle and retire to Vegas if he were living in Seattle for job market access only. However, in that case one can probably retire early and move to Vegas without caring for job market access, on the difference from the house prices. If one were rooted in the community, selling the house and downsizing is not an option (in fact I've heard older people in Seattle complain about this - the value and property taxes go up and up but they never want to sell out of the community so the appreciation is a negative for them). There are various scenarios possible, and it's not clear that the net worth in 30 years is well, worth it - liquid; you may have little time left to use it, or not even want to sell.

Auto-btc – первый в мире робот для автоматической торговли криптовалютой Биткойн
6% for realtors fees is outrageous! I had no idea it was anything like that in the US.

Here in the UK, it’s about 1.5%. That can often be haggled down to 1% if you have an expensive house that’s desirable enough to sell itself. And even that is getting majorly distributed by online agents, who are offering a flat fee service rather than % of property, which can be an enormous saving.

At 6% it seems a market with a huge amount of fat, just asking for a new player to come and disrupt
What Is Creatine, How It Works, and Should You Use Creatine
For someone coming from JS/Python, I think a major familiar property of Clojure is the dynamic nature. You can quickly try something out or iterate and it runs right away, without asking you to specify the program completely type-wise.

Clojure's data checking and testing stories are good too, with spec and the various test libs - including generative tests from specs. And of course you can share the same specs on front and back end, demonstrating a payoff of the front/back code sharing.
Thank you for your work on Beeline. I've been using it for several months and it definitely helps when diving into large Wikipedia articles, research papers, blog posts, etc. I found that it facilitates my reaching flow quickly when investigating large problems.
In Dallas, renting is generally more expensive than buying, and yet I'm still happily renting. In fact, I'm moving next month from my current 3-bedroom 1500 sq ft apartment to a (slightly-nicer) 2-bedroom 850 sq ft apartment, and cutting my monthly payment by more than a third. I previously rented a 3-bedroom 1500 sq ft house that was slightly more than the big apartment, and before that I owned an even bigger house for 13 years.

I know the numbers make it a good idea for me to buy, but I'm renting an apartment anyway, and enjoying the flexibility. If I still owned a 1500 sq ft house with three bedrooms for my kids, I'd be "stuck" with that house and the associated costs now that they've grown up and moved out. Instead I get to downsize as easily as signing a different lease, and I still have no maintenance responsibilities. To me, that is more important than the money!
> Basic map and compass training would be better than GPS

Surely any kind of hiking should include at least a little informal training in using a map and a compass. I had that in primary school in the UK. Mind you that was in the early sixties. Here in Norway children get an early introduction to simple woodcraft (shelters, fire, tools, maps, compasses) in primary school and have outings into the woods. My children would come home with a brief letter saying that a trip to the woods was planned and could we make sure that they were supplied with sausages to cook over a fire and a knife to cut sticks with to make the fire and a rudimentary shelter. And they did it before mobile phones were common too.

One of my sons was accidentally cut by a classmate but we didn't sue and he came to no lasting harm. The trip was not called off, the teacher simply and effectively bandaged it up and they all carried on. If primary school children can manage then surely 20 year olds can.

1.Force users out of Yahoo mail accounts. Its a hellish experience.
2.Dont touch anything related to user groups.
3.Optimize Flickr design with slow accurate steps.
4.Dont unify design of two services quick. Test hard before trying to mix features.
5.If you this right, you will be the only place for professionals and amateurs. The potential is huge, but the risks are there and in the process if you make really wrong decision....
6.Focus of this service must be professional only. And don't touch free service, because flickr is actually free first pay for more features second.
Wish you luck.

I think the point isn't asserting that it isn't new, rather it is a sad state of affairs that many tools are still playing catchup with developer tools of the 80's.

For example, every time we discuss Lisp on HN, many talk about SLIME, SBCL and such.

Yet, the actual modern experience of what it meant to use Lisp on its glory days lives on Allegro Common Lisp and Lispworks.

Reading papers from Xerox PARC research always makes me sad that many think replicating a PDP-11 is the ultimate developer experience.
The author described how to calculate the ratio of sale price to average monthly rental to determine if owning is cheaper or more expensive than renting in your area. In some cities (including mine), owning tends to be cheaper. In other cities (including one in which I used to live), renting tends to be cheaper.

An Expert’s Guide on Push Notifications: Why and How to Use Them
How many times will we have to debunk this "physical goods traceability through the blockchain can work and be more efficient than some random SQL database" nonsense? If you trace physical goods you need to trust people not to lie about their nature, if you have trust then you don't need a blockchain and can use something a lot cheaper and more efficient. They should put that on a banner on HN or something, it'll save everybody some time.

I assume that what IBM did was centralizing mango grower info in a database instead having to go through complicated, manual processes. They did that through a Blockchain for some reason but I'm sure you could get similar result in some PostgreSQL DB. Of course I can't know for sure because the announcement is all fluff and hype and no substance.

This has been possible for 50 years at least, and the lisp, smalltalk, and functional programmers have been doing this for a long time now.

Oversimplified statement.

You still had to put a downpayment that didn't go somewhere else for the whole length of your mortgage.

Also, if your rent covers your mortgage, I will assume that you were simply lucky enough that in your particular area the housing market rose more rapidly than in others (for example the bay area). But you didn't know this in advance and it could very well have gone the other way around.
“reserve” estimates refer to current economic viability.

The lithium production market is still a fairly new market, so even though USGS and others have made some reserve and resource estimates already, it is premature to make any firm conclusions about future resource discovery and production. We’ve learned at least one lesson from the peak oil debate: higher prices do indeed spur innovation and increased production, at least they have in the U.S. Interestingly, almost the entire increase in global oil production has come from an increase in U.S. oil production. That is, the rest of the world has barely managed to stay in place on the treadmill of oil production, even in the face of far higher oil prices.

With respect to the notion of peak lithium, there is a substantial difference between this commodity and oil because there are many ready substitutes for lithium that can be used in the manufacture of batteries. The USGS report cited by OP states: “Substitution for lithium compounds is possible in batteries, ceramics, greases, and manufactured glass. Examples are calcium and aluminum soaps as substitutes for stearates in greases; calcium, magnesium, mercury, and zinc as anode material in primary batteries; and sodic and potassic fluxes in ceramics and glass manufacture.” These substitutes may all face similar resource constraints as lithium, but there is a fundamental difference between changing battery chemistries and finding substitutes for oil more generally.

Source: https://www.greentechmedia.com/articles/read/is-there-enough...
This is all completely irrelevant, and has been discussed to death. The price of the lithium in the Tesla battery is on the order of $150. If it goes up to $1500 because we run out of easily extractable resources, it's going to be economical to extract it from seawater, where there is 230 trillion kilograms of it. Also, it might be economical to recycle the lithium from old batteries (currently it's just not worth it).
Just another anecdote, but mine is a fully different experience.

As a 6'1 white male, I find that I can walk most anywhere without fear.

I often find that I need to reassess my privileged notion that this is normal when conversing with friends who are shorter, darker or female. They describe a world much like the author of this piece does.

That's not to say I've never had trouble on the street. Years ago I was assaulted randomly by someone bigger than me stumbling out of a bar I was passing by. The difference was made clear though when I reacted by getting up and following at a distance, eventually finding a helpful police officer who never questioned my version of events.

A vastly more common scenario is one where I am never in any fear of any kind, I can easily wave at police, and am never interrogated for simply walking.
