Pcd – quickly “cd” interior components of your current dir
In the spirit of this submission:

https://news.ycombinator.com/item?id=10722647

here is something I use. Maybe they can work together?

pcd_guts()
{
local target=$1
local level=${2:-1}
local tail=""
local dir=$PWD

if [ $# -lt 1 ] ; then
printf "pcd: insufficient args\n"
return 1
fi

while [ $level -gt 0 ] ; do
tail=$(basename "$dir")/"$tail"
dir=$(dirname "$dir")
: $(( level-- ))
done

dir=$(dirname "$dir")
tail=${tail%/}

printf "%s" "\"$dir\"/$target/\"$tail\""
}

pcd()
{
local todir=$(pcd_guts "$@")
eval cd "$todir"
}

The concept:

When we change the directory, one way to look at that we are rewriting the last path component of our current working directory: we can delete it (cd ..), add a new one (cd child) or replace it (cd ../sibling).

The pcd command lets you do a replace on the component other than the last. You can specify which by number, which defaults to 1.

a/b/c $ pcd x
a/x/c $

a/b/c $ pcd x 0
a/b/x $

a/b/c $ pcd x 2
x/b/c $

pcd is helpful if you are working in a directory tree with parallel structures. You're in "proj/parser/src" but need to be in "proj/iolib/src". Just "pcd iolib".
At this point we need more techies who are willing to go into politics. Before, everything could be solved with technology and nobody really understood how to enforce things. Now everything is becoming centralized and the people in power (politicians and big companies) are dictating the rights we have on the internet.

Internet rights are important. The internet is a part of so many of the things that we do in real life that it is inexcusable to continue to treat it differently. Smart phones know where we are and who we talk to; the internet of things may someday take hold and keep track of everything we do and when we do it; AI will be regulating more and more systems.

The people who use Facebook and turn a blind eye for the sake of convenient services don't care, but many of us do.
With this stow solution, I wonder what happens when some program makes modifications directly to its own configuration files, without being aware that they're not directly under your home directory but symlinked under dotfiles somewhere. Will the symlinked file get modified? Or will the symlink be removed completely and a new file be put in its place, directly under your home directory and not under your stow directory at all.

One program which I'm thinking of that can make modifications of its own config files is znc. weechat is another. There might be some other random program that does this too. I'm concerned that using stow for them might lead to disaster.

Any advice from someone who's tried it with apps like that?

Pages like https://aws.amazon.com/ec2/pricing use a JSONP request to get a big messy chunk of pricing data. I have parsed that, and serve it with a custom API that does the calculations from the Cloudcraft backend to the React-based frontend.

However, AWS just announced a proper pricing API! Check out https://aws.amazon.com/blogs/aws/new-aws-price-list-api
This will make life much easier, it does however not yet cover all services, for example ElastiCache is still missing while Cloudcraft already serves pricing for it.

What Orwell can teach us about the language of terror and war
This, too many times over. My wife and I are older parents, and despite our highly privileged income stratum I'm still shocked at the costs of parenthood (and we're still several years off having to pay $25-30K/year for private school). Meanwhile, some of my wife's youngest (early 20s) employees are starting to have kids while dealing with relatively low salaries, overwhelming student debt, and high levels of employment instability. I have no idea how they'll do it and, if we want to consider ourselves a decent society, we should have support mechanisms in place to help them do it.

Your only quantitative argument is an additional 1 in 10,000 risk of the mother's death. So what? It's almost nothing. Why would anyone advance parenthood by years to avoid such a small risk?

Furthermore, your allusions to chromosomal abnormalities are a eugenic argument. That could be interesting if uncomfortable, but to present it so casually is disappointing. If you're going to go there, please do it with arguments that are well considered and framed in a way that is subject to refutation.

A gun isn't effective unless human loads it, aims it and pulls the trigger. All your other examples are the same. We do not have any machine that can build a copy of its self, even with infinite energy and raw materials just lying around nearby.

Well, it depends on what you mean, I suppose. I've integrated Emacs with tools like those, so that I can (for example) get linting feedback on code in real time, or jump to locations from a unit test failure report. But I've never written unit tests, or used coverage or static analysis tools, that depended on Emacs, or indeed on any other editor. I've never even seen that kind of tight coupling, much less perpetrated it myself. I'm not sure whether that's what you're talking about, or whether it only sounds like that's what you're talking about, but I hope it's the latter.

One of my friends tried to adopt, it was a nightmare.

Anyone suggesting "GPS tracking" with any degree of seriousness doesn't demonstrate the ability to form rational thought: discussion should not continue.

Anything less than free is exactly a poll tax. This is also a great way to backdoor a registry of individuals, since, you generally need to track which people have completed the feel-good training.
I worked for a delivery company in the Bay Area at two different times and the first time I had to learn every street of two cities, and the second time I was provided with printed out turn by turn directions for another city. The 'knowledge' part was horrible to learn but I eventually enjoyed knowing it (during my time with the company), while the printed GPS part was easy to use the whole time.

So the question becomes is there a reason nowadays to learn the 'knowledge' part by heart? Not really. It's nice to know while you need it but is otherwise quite useless information because it doesn't teach you anything.

> drones justify terrorism because it's the only available
> response to fighters from the "other side".

We had similar terrorist attacks before we had drones, read what the
likes of Bin Laden said about why 9/11 happened. It's because the
infidels are on their homeland, not because they're using some
specific technology to attack them.

More generally people resort to terrorism in the face of an
overwhelming enemy. The west could relatively easily win the wars
they're fighting now in the middle-east with their WWI armies if they
were willing to care less about civilian casualties, that's how
lopsided the odds are.

> Thinking we can wage wars without risk to ourselves or our
> "soldiers" is preposterous.

Drones as a technology would happen regardless of whether or not the
armies developing them were concerned about their own
soldiers. They're simply the logical next step in technology,
e.g. fighter jet development has stalled to some extent not because
the technology has reached its limits, but because if you pull more
G's than you do now the pilots might die.

"We argue that the growing income inequality over the past three decades created both a group of women who can afford to buy services that help them raise their children and run their homes, and a group who is willing to supply these services cheaply."

Somehow this sentence makes me very uneasy. Rich people start having more kids because they can pay poor people to take care of them.

This "everything as a service" trend of modern society is very scary because it relies heavily on income inequality, I can foresee a time in the near future where we will go back to feudal laws, a rich person will own a domain and have poor people taking care of it on their behalf.

There's a possible bias in that the better cabbies may be less likely to use GPS in the first place of course.

I'm not sure what you would consider politically correct here, but this article has some political involvement.

This for example:

European Commission published a special report on women in decision-making positions, suggesting legislation to achieve balanced representation of women and men on company boards. Some countries – such as Norway, France, Italy, Belgium and the Netherlands – have already taken legal measures in that direction.

[...]

we find, however, that while highly educated women had fewer kids than women with lesser education in the US until the 1990s, it is no longer true today.

Seems to address the question on whether there should be more regulation to help pregnant women.

Well, since you ask, I wouldn't post it as it doesn't seem to have anything of HN interest ("people exist who have done interesting things" isn't all that great of an article to start with, it being in a marketing context cuts it down even more), but apparently 47 people disagreed, so shrug. I do sometimes wonder if there's a substantial contingent of people who upvote things based on the title alone, bolstered by the occasional appearance of commenters who have clearly only read the title, but there's no way for me to prove it either way. (And that's an observation well beyond just this one article, btw, not a targeted thing.)
This is dangerous thinking. That we don't understand the factors that go into this means we don't know if it actually is good for any genetic pool.

How is that a feature? The user's explicitly asking for this.

This feature reminds me of vim, that suggests closing with ":quit" when you press C-x C-c (i.e. the keychord to close emacs). It knows full well what you want to do and even has special code to handle it, but then insists to hand you more work.

Let me introduce a different point of view.

A toddler will try to grasp any small and 'cute' animal at sight. Is part of their human inquisitive nature. Children do not keep animals because all of they are little sadist jailers; they normally do this because are curious, want to understand any novelty around and have the basic impulse to protect, make lots of 'pet friends' or even experiment playing parent roles (with their 'subrogated sons').

And this is good, not bad. Even if some random insect or snail die eventually. This is totally the opposite of a sadistic behaviour.

Children feel the normal urge to explore, control and manipulate their environment. A child that do not show any interest for the real world is either autistic, sick, or have a serious problem that needs to be addressed (like being abused for example). Therefore, parents have to teach them about the typical outdoor dangers. This includes what animals to avoid at any cost, and how to manage the other animals that could deliver a bite leading to a sored thumb, like crabs or crickets.

To make a children responsible of the life of a pet and to teach him/her to adopt a routine (of feeding, changing water and caring of their beloved pet) is an invaluable experience that any boy and girl in the planet should have once at least. Humans and errors are linked concepts. I think that is much less traumatic for a boy to kill a short-lived cricket or grasshopper because they forgot to refill a bowl with water the last weekend, than to kill a canary or a cat by a similar mistake.

I think also that children need to understand that sometimes illness and death happen. To avoid a children any (reasonable, controlled, human) exposure to death will probably lead to a shelfish or stunned adult that will not touch their ill old parents with a ten foot pole. Everybody will die and our sons need be armed psychologically against this moment of mourn and lose, and have the opportunity to learn from family and adult friends what to do about this.

A pokemon or virtual pet can not provide the same experience. Life is not like a video-game that can be reiniciated as many times as you want, and children need to understand that when a pet die will not return to life again pressing some buttons, that is lost, and that to feel bad about this is normal.

Interesting how people complain about violating the 4th Amendment but act outraged over the 2nd. One could argue eliminating both would make us safer. It's also interesting how the pro-4th crowd seems to often fall into the anti-2nd crowd. Too much hypocrisy these days from the politicians. It would also seem that the 10th is often ignored as well.
