One thing that has amazingly never improved for 20 years. That's when your internet connection does not work. It could be anything from:

1. your computer broke
2. your network/wifi card failed
3. your wifi access point failed
4. your hub/switch failed
5. your router failed
6. your cable modem failed
7. your ISP failed
8. the URL you were trying to reach failed

The error message you get is just a generic one with no clue at all.
Thank you so much, this is the first time I’ve seen this explained in terms I fully grasp. I was getting to the point of wondering whether or not these articles were submarines, but your explanation is far more cogent.
The same could be said about any variety of apple; they are cuttings grafted onto rootstock. The grafted sections were cut from a tree of that variety, which was grafted from another one of that sort, going back all the way to the original one of that variety that was discovered (most likely thanks to Johnny Appleseed). Apples are clones, just like bananas; sexual reproduction of apples creates in most cases, apples which aren't good for eating. I suppose with apples, one difference is that you can use different rootstocks for some diversity and resistance against soil-borne diseases.

Oh if only this were true. Just so we're clear when you say "established global currency", what you're saying in practice is "SWIFT" (and a few "competitors").

Ok, so one of the problems things like bitcoin solve is that trust in the currency really encompasses trusting quite a few organisations, and these being trustworthy is only true up to a certain transaction size, and only on large averages. Basically, the issue is that banks can't be trusted, and therefore anyone big enough to make double-digit million value transactions can't be trusted (because they might be the bank, own the bank, or simply owe the bank a lot of money, ...). There are also more complex cases where governments get involved and muck things up (financial fraud, bankruptcy cases, tax investigations, ...). And there are other cases (terrorist financing, sanctions, ...).

All of those problems should not be the concern of merchants, but they are in practice, because governments have unilaterally decided that interfering without recourse in payment systems is the way they'll police the world. So they change payment streams (which are between 2 parties, say A and B, and they have some problem with A). Issue is always the same: B buys something from A. One of the parties in the chain, or a government, or the police, or ... has a bill for A, and halts the payment. A then claims (truthfully) non-reception of funds and refuses to deliver. B is left without recourse, without money, and without the good they paid for. Needless to say, nobody accepts responsibility for damaging B. But it gets worse.

So in fact this is one of the big advantages of cryptocurrencies, actually. With dollars (or any such currency), even if they're on your bank account they can disappear months later.

Essentially, large banks, judicial system and governments have the ability to impose their losses on others, in the "traditional" currency systems, and they use that ability too much, without caring who else they damage in the process.

When it comes to "if I have the money, I can trust that I actually have it" cryptocurrencies (all of them) are far superior to SWIFT (essentially all banks are part of SWIFT) in terms of what merchants consider trustworthiness.

There are other advantages that they also have. For instance, despite the complaints, bitcoin is still far faster than SWIFT.
I like the infinite space view. Continuing with the theme of the post: this is a clever music video visualization for J.S. Bach Cello Suite No. 1 - Prelude:

It's more than possible -- it's well-documented with some kinds of meditative practice. [1]

The only interesting question this article raises for a knowledgeable person is whether or not the Sanskrit language _itself_ would have an effect on cognition, but it never succeeds to prove it would or offer a mechanism for how it would work, and instead asks for funds for more studies.

I'm not sure about that. Coming up with something new that millions of people like is the hard part. It matters not if you can duplicate it easily. Just look at Minecraft, compared to AAA games it is simple, yet its simplicity is genius.

Steep learning curve just means learning quickly, usually I’ve heard it used for being /forced/ to learn quickly, as a type of hardship.

I disagree with the article that “steep learning curve” implies something learned easily, and neither does it imply something difficult to learn. It refers solely to rate of learning. Other interpretations are innumerate.

Really ? Why ?

The price for any good is the marginal price. Essentially it's the price that should get paid for having a "single item" of the good change hands. Take a stock. MS stock may be quoted at 80$, but I guarantee that if you want 50% of MS stock, you'll have to pay more than 80$ per share.

So prices for large or much smaller quantities of the good change hands are different, and are not quoted unless required. (smaller than one would be still one, but only selling after the seller has to wait a long time). Since such transactions often substantially change the demand for the good, the fact that such a transaction exists often substantially changes the price.

This is true for cryptocurrencies, stocks, cars, shavers, toilet paper.

Apparently bananas as we know them are a mostly sterile hybrid of two other trees.

They self propagate like you say (but humans also spread them around). Bananas have a near zero rate of sexual reproduction, if you can get one to produce a seed, it's viability is low.

If you can get the seed to germinate, the resulting "offspring" from that will be distinct from the original banana, a new variety. It will not necessarily be "true to seed". It might be a better banana, or worse.

If you plant a lettuce seed you will get the same lettuce, year over year. Same with peppers and tomatoes, etc. Their traits were bred instead of cloned.

Ask HN: What would you say about Software Development at a Career Day?
I've been asked by my wife's old high school to speak at Career Day as a software developer. I have some ideas as to points I want to make, but I would welcome other suggestions. I'm recently retired after 33 years of development so I hope to bring some long view suggestions as well as shorter views. The high schoolers have had some programming classes over the years, and I think there are several people speaking at the same time so the ones coming to listen to me have an interest.

2000 character limit so I'll put some points I want to make in the comments. What would you add to a presentation for this?
Performance, mostly.

Operating systems have tweaked the performance of user->kernel transitions to the point that anything placed on that path represents massive degradation in performance.

Until we start having to pay performance for security, no one is going to bother. Meltdown and Spectre are really the first security attacks that will require significant amounts of performance to mitigate.

Once we get enough of those kinds of attacks, people will start being willing to trade performance for security.

Get familiar with Linux. They've probably just done programming on Windows machines, but any server work, or data science or scientific programming will involve Linux and if they don't know their way around it they'll be behind.

Startup vs. bigger company. Startup can give you more intense experience, handy when young, but bigger company can give you more stability and reasonable hours, plus if you get in at a "name" company that will look good on your resume in the future.

Web development, the holy trinity HTML/CSS/Javascript. Mention Node, can get you frontend and back end.

Java is in demand at bigger places, will be for short and medium term future.

Mobile development. Developing an app or game by yourself or at a small company won't get you a lot of money, not many people download apps except for the big ones you all use. You can do app development at a bigger company, bank or other places.

Data science/AI. There's going to be a lot of demand for this in the future. I'll mention a few uses, cancer detection, bots. Pay attention to statistics and linear algebra, and near term Python is the language that's used for data science.

Concluding points. It's a career, perhaps more than any other, that requires lifelong learning. After 33 years there's been changes in languages that are used, the tools used, the state of the art seems to pivot every 5 years, and the good ones make the effor to keep up. There's a saying in development about being a developer with 20 years experience vs. one that has one year of experience repeated 20 times.

Lots and lots of software uses aspects of capability design internally, sometimes intentionally, sometimes by accident.

In particular, many IPC mechanisms that involve more than a few parties interacting -- especially when some or all parties are intended to be sandboxed -- become capability systems.

Examples of real-world capability systems include:

- Android's Binder

- Chrome's Mojo

- FreeBSD's Capsicum

- Linux's Bus1 (not yet merged into mainline)

- Classical Unix domain sockets (in that you can pass a file descriptor over a socket).

- Cap'n Proto RPC, especially as used in Sandstorm.io (disclosure: these are my creations)

- The Google Docs "anyone with the link can access" mode and e-mail invitations to non-Google accounts (this is a relatively weak and unintentional capability system).

- OAuth 2's use of bearer tokens (also relatively weak).

> does this imply that the capability design only works internally and you cannot pass caps to other applications?

It's best if the applications agree on a capability protocol, but in some cases you can trick applications into behaving in a capability-based way without explicit support. For example, using secret, unguessable URLs can allow for capability-like design patterns -- although at the risk that secret URLs are relatively easy to leak (stronger capability systems can protect against accidental leakage).
> So, I guess that makes me complicit in all this too.

No, that makes the salespeople, and your bosses at that communications company, complicit. We're just as neutral and tool-like as the computers we program.
> 1. Juniper and Cisco aren't nearly as important as they used to be and their importance is growing less every day.

If I were running a multi-billion ISP, I'd use Juniper and Cisco gear too.

> 2. Network technology almost certainly improves by 25%+ per year in terms of price-to-performance. Generational upgrades will make it uneven but that's not an unrealistic number to hit on average.

It took 12 years to go from 10 gigabit ethernet to 100 gigabit (about 21% per year over the decade), but I'd be very surprised if the price was the same (i.e. that 100 gig switches cost the same now as 10 gig switches cost back then). Carriers and data centers moved directly from 1G to 10G. But it seems like with 100G, there is significant pricing back pressure creating the need for intermediate speeds: http://www.mellanox.com/blog/2016/03/25-is-the-new-10-50-is-....

But let's say a 100G router today costs the same as a 10G router cost 12 years ago. 21% per year is just about what you need to keep up with projected demand growth over the next five years: https://www.cisco.com/c/dam/m/en_us/solutions/service-provid.... Even if 100% of your cost was scalable at the same level, you're talking about keeping up with demand for the same money, not less money. Of course, 100% of your costs aren't scalable. The last mile DOCSIS part of your network is not scaling 20% per year.

> 3. The "last mile" is the hard part but sticking with cable (DOCSIS) technology is not a requirement.

Verizon tried that. It's barely breaking even on FiOS even though the average FiOS customer brings in more than $100/month in revenue.

> There's no reason we couldn't have a massive federal Fiber To The Home program that cuts through current regulations.

I can think of way better uses for hundreds of billions of federal dollars than subsidizing Netflix's business model: http://www.afr.com/technology/web/nbn/australias-highspeed-i.... For the forseeable future, fiber is a luxury product, and to the extent we want government-funded broadband to address "Internet access as a human right" issues, we should do it using cost-effective 5G wireless technology.

> The one-time costs are undeniable but they can be easily and predictably amortized over a long period of time. The theory that networking technology can't keep up is technically baseless.

It's not that networking can't keep up. It's that upgrading the existing cable network to keep up with demand growth is expensive, and replacing everything with fiber is even more expensive.
Indeed. It's already starting to happen:

It's kind of unbelievable that NPM is a for-profit company that serves the node community for free. You can't possibly expect them to make the right choices when the community isn't whom they are directly responsible to. NPM should be a nonprofit foundation, a coop, or some other organization that has its operations funded by the community and has elected positions.

Their lack of financial or other interests in the community directly explains their policies.

Also equally important and related to the article is messages on exceptions raised by libraries used by developers. I think this is one of the primary reasons why I found some Python's open sourced libraries like Numpy or Pandas easy to learn. Most of the messages when an exception is raised are specific and helpful in helping me fixing the error.
I incorporated at the very beginning, after a few beers at 2am. Ignorant of the law, I thought it was necessary to form right away.

You're talking of physical properties.

In terms of software, a perfect example is Microsoft.

I'm not saying it's unwise to upgrade technology, but things tend to stick around for a long time. Because it works.

The amount of time and resources it takes for the skill gap to close when you're talking about a core techongoly that almost any IT person is knowledgeable in. It's insane. We're talking generations.

It's going to take a long time for that to change.

Your example of the file open dialog box is identical to what Apple did on MacOS when they implemented sandboxing. Rather than using regular paths in NSString objects, they return you an NSURL with a "security scope" - a capability. These can be saved and reused across process terminations.

A disproportionate number of the apples in the grocery store have MacIntosh in their ancestry and are basically variants of them. There's not a wide variety of genetic diversity among eating apples, despite apples having a couple milennia of breeding history, a huge number of varieties (historical and current), and fairly diverse genetics. Consumers seem have a fairly narrow palette in what they consider to be a good eating apple.
