The biggest problem is that stealth has always been surrounded by political demands all the way back to the first stealth aircraft. Given Sprey's target audience with the interview and the way he chose his words (particularly at first), I think it's likely that he was addressing the prevailing belief that stealth aircraft are invisible aircraft. That said, you've hit the nail on the head in terms of the difference between being stealth (re: invisible, such as what Sprey's railing against) and being low-observable.

Public comments about the JSF program by Lockheed, military spokespersons, and congressional supporters alike have all touted the plane's stealth capabilities to an extent that makes me wonder how many actually understand the difference between the two. Given the likelihood that operational demands (particularly close air support for the Marines with the F-35B... not that CAS missions could every be very stealthy) will make the entire point moot, I really don't understand all the emphasis on it.

Ask HN: Feedback for my first landing page to validate my idea
Dear HNers,

Just created my first landing page to validate my idea and wanted to get some feedback from the community. Followed patio11's advice as much as I can about communicating benefits instead of features.

Would also like to connect with independent consultants to understand the tools that you use to manage projects.

Part of the reason why defense companies are risk-averse and bureaucratic is because things just CANNOT fail. It's not like, oh yea, my program crashed, I'm just gonna fix this bug and re-compile. No, if your jet crashes on its first test flight, the pilot is going to die. If one thing is wrong with a space satellite, yea no, you cannot pull it back down to Earth to fix it up.

Thought it was newer, had friend that started his second day (today) on Soylent with positive results.
Former employee here. I had a very opposite experience. New features were key for promotion. Performance/stability tweaks or bug fixes would only add to your promotion chances if they had a demonstrably large impact.

I wasn't at that level but this was super true for L5-L6ish engineers or above. Yes they had to tackle bugs, but they weren't getting to L6 unless they led an effort for a big feature within a project, or L7 unless they launched a project with a solid impact.

Management made efforts to give more weight to refactoring, but it seemed like a token effort. Refactoring was thankless unless it was a truly gargantuan change.

Working at google was great, but the engineering incentive structure is far from perfect.
I noticed that Linkedin has been trying to push content too with the influencers' posts and Pulse recommended articles. I am skeptical that they'll be able to get a lot of traction with that kind of content though.

I am just curious why they have not pushed Q&A as another engagement channel, something similar to Quora. As most people in Linkedin use real identity, the Q&A should be relatively high quality with little spam. Thinking about it, maybe Linkedin should buy Quora or Stackoverflow :)

Meh, so many companies do this, it's not new or evil.
Google's system is promotion-by-committee. It ends up having the same pros and cons as any committee-based system. On one hand, it avoids the kind of egregious mistakes and crimes that occur when too much power (i.e. to promote others) is vested in individual people (e.g. managers). On the other hand, committees are risk-adverse and will shy away from controversial actions. People who do good work following expected patterns get promoted. People who do controversial work, or who don't fit into an obvious mold, will have a tougher time, as a committee that can't come to agreement will default to no action.
Sigh. "grow-only", "rebase is dangerous", "detached head state is dangerous". STOP. Stop it now.

git is a bag of commits organized into a tree (a tree of Merkle hash chains). Branches and tags are symbolic names for these. Think of it this way and there's no danger.

Indeed, published repos/branches must not be rebased. That's what receive hooks are for: to reject non-fast-forward merges. If you don't understand a word of the previous sentence, don't worry: you're just not ready to run a public repo.

What is dangerous is:

- pruning repositories

- lack of pushable (and pullable) reflogs

Reflogs are what makes it easy to recover if you lose a symbolic name and you're left with a pile of commits you'd not find your way through: the reflog tells you what you did and gives you the commit hashes you need to find your way home.

I often push from detached head state, and I did so today. Here's what I did:

$ git remote add contributor https://github.com/contributor/project
$ git fetch contributor
$ git checkout contributor/their-branch
$ git rebase -i origin/master
<fix up some things>
$ git push origin HEAD:master
$ git checkout master
$ git merge origin/master

Yes, that's advanced usage, and in particular the push command-line can be dangerous, so learn exactly what "git push origin HEAD:master" means before copying that, but compare now to the crutches equivalent of the above:

$ git remote add contributor https://github.com/contributor/project
$ git fetch contributor
$ git checkout contributor/their-branch
$ git checkout -b their-branch
$ git rebase -i master
<fix up some things>
$ git push origin master
$ git checkout master

Or, maybe I could have told the contributor to rebase and fix those things. Or maybe I could have merged the contribution and then committed said fixes. But I like clean history -- I've been taught to by the very best.

I didn't need a local branch crutch to find my way around because I know the model: a tree of commits.

Understanding the model is the key.

There are other VCSes that also use Merkle hash trees. Internally they have the power that git has. Mercurial's language for expressing refs is great. Fossil has all the power of SQL, and it shows. But they all try oh so hard to hide the model from me. It's not like hiding what a process is from a non-developer user. SourceTree does a great job allowing non-developers to understand their version trees, so I know this is not too hard on non-developers. Yes, non-developers should mostly never rebase, but detached head state is useful for them: because sometimes they need to "see" old versions, so they end up branching, and so they end up merging, and guess what: merging is what's not easy for them.

If you want to help non-developers use a VCS, give them a better UI for dealing with diffs. Don't punish the rest of us by hiding the wrong thing from everyone.
We are doubling down on the product. We want to make sure everything is extremely stable first. We have an awesome roadmap that we will be sharing on the blog soon that outlines our plans to make filepicker the best service for dealing with files.

As I understand it, they want to perform a feasibility study to determine if a mothership (balloon or lander) and daughtership (rotorcraft, maybe a quadcopter) combination would be an effective way to study Titan.

The mothership would act as a base of operations; a recharging station at the least, probably containing communication devices and its own sensors as well.

The daughtership, potentially multiple daughterships, would sortie out from the mothership and investigate the surface up close.

They outline 4 outcomes from the initial study:

(1) develop mission concepts of operations for deployment from a lander or balloon to acquire context imaging and mapping data, to sample from solid surfaces and/or lakes, and to return to the mothership to deposit samples and/or recharge;

(2) develop a parametric sizing model of the daughtercraft to characterize propulsion, power, range, endurance, and payload capability for total daughtercraft mass ranging from approximately 1 to 10 kg;

(3) develop a conceptual design and identify representative components for the entire daughtercraft hardware and software system for autonomous mobility, including estimates of approximate mass, power, and energy budgets and producing a representative CAD model; and

(4) develop a conceptual design and preliminary CAD model for a science payload on the daughtercraft, including specifying a nominal instrument suite on the balloon or lander, designing a compatible sampling mechanism to acquire solid and/or liquid samples on the daughtercraft, and studying mechanisms and daughtercraft behaviors necessary to transfer the samples to the instruments.

The study will be carried out by JPL.

----

I wonder how much the rotorcraft community (hobbyist or otherwise) could contribute to a study like this. I can imagine this would be extremely interesting, and not so different from the many applications already being investigated.
The difference is that OpenSSL updating was the responsibility of the admins maintaining the server, not general public. The general public did have to act, but it wasn't something technical like updating firmware on a phone is.

Back in the day, I had an S60 phone but no way to even connect it to a computer to get the firmware.
Paying developers to port their apps is completely legitamete. It's a chicken and egg problem. Users don't want to use the platform because there are few apps, but developers don't want to write apps because there are few users. If Microsoft can spend some money to get additional apps in the store it's just a business decision. In my opinion they should have dedicated more money to that program.

This on the other hand is deceptive and I think pretty embarrassing. Completely different scenarios.

Maybe "hiding what a process is" is not that good an analogy for "hiding what a modern VCS is under the covers", after all, users know to use task killers on just about... every OS. Or maybe that is a good analogy: users need to know how to kill runaway/non-responsive apps. Calling processes "tasks" or "apps", or something that will mean more to users is a very good idea, but you can't entirely hide the concept from them. (For many elderly people even that is too much.)

Here's what I think might help users: a) better diff/merge tools (like github's new image diffs), b) better integration with VCSes in every application that produces content (e.g., Adobe Photoshop), c) better visualization of the history tree.

For (c) I'm thinking of a D3-style graph, with recent branches taking prominence (whether named or not). Mouse around the graph to pick out branches, mouse over commits/heads to get a blurb (branch/tag name, last commit metadata). Something that feels alive and dynamic. Not these static, boring branching graphs we've all seen before that look like SVG renderings of ASCII art graphs taken from manpages. Static graphs become difficult to display and use when the number of branches increases past a handful.

> as far as I can tell there is no rule that determines what places get a "the" and which do not.

I was recently looking up the difference between "the Ukraine" and "Ukraine," because people really prefer the second. It was said that 'the' is used when shortening the name: "the Bahamas" instead of "Kingdom of the Bahamas." "The Ukraine" comes from when it was a territory of the USSR, rather than a country in its own right, and when it gained independence, it was just "Ukraine."

Some food for thought.

I would say that people do this. Silicon Valley does not do this "without thought or direction," but instead with great forethought and direction in the form of a "business plan."

The problem I see with this, is that this is not some earnest effort to improve photo sharing, but an obvious attempt to clone an existing and popular service with the hope of mining its popularity.

Truly the developers of this cannot think they created "a new way to share photos and video," unless they are ill. All they have done is applied a modest novelty to an existing concept. Not quite a "mutation" in the sense of a new species of Finch, but more in the vein of a parasite.

It depends on how much money you earn and where you live, mainly. If you make < 100k a year U.S. and pay taxes on it in the country you live in, you can get by with a 1040 and one or two extra forms as far as the IRS goes, and not have to pay the U.S. anything in income taxes.

However, the issue with the WSJ article, where you would also have to disclose retirement and savings accounts or pay a penalty can be an unpleasant surprise for people. Makes me want to just put everything in my spouse's name and pretend the U.S. government doesn't exist.

Pretty much all companies have levels. Even if it's not something as set in stone as Google's 1-11, or Microsoft's 59+, there's almost always some sort of differentiator, from something as small as "Senior" or "Junior" to denote experience.
That's a great picture. High information density but easy to read.
I was once involved in developing a system like the one you describe, and it turns out it's a really hard problem, because for most non-trivial articles you want to do more than just skip a paragraph: you cut an explanation here, which means you need another word there and possibly that sentence doesn't make sense anymore so you'd rewrite that... and as a result, as a copy editor, you very quickly lose track of the flow of a story if there's two or more different variants all merged into one.

You mention elsewhere that "It potentially saves copy editors a lot of work." but I think you'd have to be a pretty darn good copy editor to keep multiple versions of a story in your head at the same time and ensure all of them keep their flow and coherence. Perhaps it really just is faster to read and edit any and all versions of a story separately.

What you're describing could work, but only if people changed the way they wrote to make it easy to cut things out without having to rewrite other things. But then you're back to something like the inverted pyramid.

What we ended up doing instead was to give authors the ability to "fork" stories into different editions that are, from that moment on, edited completely independently from each other, but behind the scenes keep track of which parts of the story are still the same, so you can provide intelligent diffs, notifications and potentially even merges like "In the web edition it talks about a guy named Jon but the print edition refers to John -- which is it?" without changing the experience for writers and editors too much.
For a while, this was a really good way to become a millionaire. Then Facebook IPO'd and we had to settle for "I'm already doing Larry's job...for a startup."

It's still roughly the same answer. Likely later this year. Certainly not from lack of want! More just because you'd have to sign up / install so many different services: firebase, elastic search, app engine for image resizing, mailgun or something for emails. There's just a lot of pieces.
I'm a PM and feel this is the case as well. I've seen massive migrations as one type of 'maintenance' wrapped as a launch that led to promotions, but generally the best way to go about it was join a rapidly growing project (G+) with user-facing impact.
