Indeed. It will be embarrassing if the libreSSL turns out to be as buggy as its predcessor from the get go. Rewriting everything from a scratch does not necessary lead to better code unless methodologies change too. OpenBSD guys should open up their test suites (are there any) in order to gain credibility with their rewrite efforts.

Scaling Lessons from the Fastest Growing SaaS Company Ever
PR is a big thing especially with private rockets. On the CRS-1 mission, they referred to the engine anomaly that occured During ascent as a "rapid unscheduled disassembly" when really it was a rupture in the engine fuel dome. Luckily the Falcon has an engine out capability so it still completed its primary mission. Had this been a NASA or other public company like ULA, the vehicle would've been grounded for X amount of months pending investigation, which in the case of SpaceX, would kill it's revenue stream. No launch, no profit.

that's partially why ULA keeps both the ATLAS and Delta family rockets. If one is grounded you have the other to rely on. SpaceX only has the Falcon. Hell, even the Millenium Falcon had problems with its hyperdrive.

Not trying to knock SpaceX here, I'm actually trying to get a job with them in aerospace engineering. They just have both an advantage and disadvantage by having one rocket system.

I doubt think people forget it, but I do think many people actually consider protectionism a good thing (not "abuse"), and many more people either haven't ever learned or thought about these policies. The negative stereotypes of car salesmen doesn't require people to know the history of the political struggle between automobile manufacturers and dealers.

Seriously. Five pages of calculus? Come on. A real cheat sheet might have:

* Optimal asymptotic time/space efficiencies for the most important problems

* The best known exponent for matrix multiplication

* Names and definitions of some popular complexity classes

* Some common but not obvious big/little O comparisons

* Dual conversions from optimization

* Probabilistic bounds used all over CS (Chernoff, Chebyshev)

* Basic facts about spectral graph theory

* The most often used inequalities like (1-x) < e^{-x} that follow from Taylor expansions

* Best known approximation ratios for various problems

* Central open conjectures like P vs NP and the unique games conjecture

* VC/margin bounds from learning theory

I could go on...

The current franchise model serves dealers well, but it really shortchanges customers, to the point that I'd even pay a bit more to buy my car from company directly.
David Graeber has made me not trust any allusions to archeological events which aren't based in archeological understanding. We have had bureaucracies since at least the Sumerians, and its growth has not been monotonic across the last 5,000+ years, which the paragraph you quoted implies.

Presumably many people died or were injured, and property and landscape burned down during the development of fire as a commodity item. While there was no formal budget or currency, lives, property, and R&D time surely are not zero in the budget.

It's also a bit odd to refer to the incalculable benefits from a process done by our Homo erectus ancestor. The controlled use of fire surely pales in significance to our early tetrapod ancestors who learned to live on land.

So this analyst wants to write code
Shameless plug here: I have been in systems/data/business analyst roles for 3 years now (F500), and I want to write code. I understand systems, I would just need someone to teach me a little bit and I will run wild.

Interested in haxe, go and <>javascript. Great at Excel. Wrote some C# for one of the big guys as an intern, then got sucked into more "strategic positions"

Am I misguided here? Is the grass just brown and poopy on the otherside? Help (hire) me write code?

I have what it takes, do you?
I've always seen rent defined as payment collected in excess of the seller's cost to make and hand over the product (not the whole product line, just the individual item). In a perfectly competitive market, price is driven down to match that cost, but the comparison with production cost is easier to apply in markets that aren't perfectly competitive (like licenses for a particular patent). Once an invention has been developed, the marginal cost (to the inventor) of someone else's use of that invention is zero. Any license fee at all that the inventor collects is in excess of what it costs the inventor for the licensee to use the invention, so the license fee is rent.
Then you do have the option. Maybe email us (hn@ycombinator.com) if you're still not seeing it?
Agreed. I'd say the wargames are out there in places, just not as widespread as they should be, and I would love to see more of them. When I was a new Air Force officer in 2004, there was a school called Air and Space Basic Course that we went through. We played a wargame there where we simulated an Air Operations Center, with targeting, planning, deployment and so on. Basically, picking targets, building strike packages, considering logistics and intel, and so on. I enjoyed it and I think it did a good job of putting us in the mindset of what the Air Force really does. There was also a modified version of Starcraft we played as a team, with planning and targeting involved. (and I played a lot of Starcraft in college so I had no problem with that exercise...)

Turns out there's a old page that describes both of those here: http://www.au.af.mil/au/cf/au_catalog_1999_2000/catalog2000_... I've been out a few years, but I think I heard that (unfortunately) ASBC got shut down as part of budget cuts a few years ago. Hopefully some of this is replicated in the other schools officers go to.
> party would be successful in the U.S

No party besides the democrat or republican party will be successful in the US because first past the post is a fundamentally broken model of democracy that always reduces into a base case of two parties. Combine that with the power of money in politics and gerrymandering and there is no way to fathom competition at the federal level.

> is appalling and disheartening.

For the most part American voters have demonstrated a lack of care for the aftermath of the financial crisis, given how they brought back a Republican majority in congress only four years after realizing how well that worked in the decade prior.

Which is mostly disingenuous, given how politicians in America are all consistently cut from the same cloth and serving the same (private) interests.

> are inheriting the current system

You actually aren't inheriting anything. Youth unemployment at an all time high, average income of bachelors graduates being around 26k a year, the lowest rates of property ownership in half a century, wealth concentration as high as the roaring twenties. The aging with power and money are holding onto it to their grave, and then only their blessed decedents will inherit the means of production. There is no mechanism to disseminate concentrated wealth back into the masses, especially the youth, anymore. Economics used to promote that, and policy used to enable that, but as we approach post-scarcity both have been sabotaged by generations that want to maintain control and power perpetually.

I would really like to work from home one day per week. But all in all, I enjoy the interaction with my coworkers. I have a strong reclusive streak, and being forced to interact with other all day has a positive effect on me.

Also, I live in the city, but my workplace is in a pretty rural area, next to a field. On my way to work, and from my office, I get to see rabbits, roe deer, horses, cows, a kestrel hunting... I would not get to see any of that if I worked from home. I do feel a little guilty at times for staring out the window so much, but having grown up in the city, I totally love that awesome view.

See also: The Law of Rent

Land, and natural opportunities in general, are the original and most fundamental source of rent.

Even the electromagnetic spectrum is monopolized. And although the holders of these exclusive rights do pay the FCC, they pay very little compared to the actual value.

Likewise, people pay very little in taxes compared to the true value of their land. Imagine if instead of having to pay income taxes and sales taxes, which disincentivize labor and business, we instead charged people for the use of land.

We could reform property taxes such that we exempt all building and improvement value, and just tax land.

This would encourage efficient use of land, reduce sprawl, and boost productivity because it would remove the deadweight loss of other taxes.

It would also be cheaper and simpler to collect, and less invasive.

Yes. Stresses the point it was almost impossbile to get thrown out. IMO the failure of the pirate party was the result of the refusal to excude anybody. Absolutely no standard of decency or adherence to any kind of policy or political agenda was required. For Mailinglist or webforums that works quite well. But not for a political party, these require some kind of shared values. Not feeding the trolls is pointless if the newspapers are feeding them.
AFAIK top-level plpgsql statements (including DO blocks run in psql) execute in a single transaction

This is true according to the docs. Anonymous code blocks are "transient anonymous functions", and functions are executed within a transaction.

The selected rows would be locked for update, delete, and select for updates, but not for regular reads. Perhaps his users table is used primarily for reads, which made this command run with negligible consequences?

> I think Musk should open an engineering management consulting firm, and hire a few smart people to analyze SpaceX and transfer some of its engineering management methodologies into a set of training modules.

It's a nice idea, but it wouldn't make any sense. Big institutions are arranged a certain way because of the incentives. You're not going to change the incentives because the people at the top fundamentally don't understand the way R&D works. Further, big organizations tend to reward a track record of successes no matter how small, rather than rewarding herculean efforts that only succeed halfway (or fail). The culture is generally anathema to taking risk.

Because the organizations are the way they are, nothing will change unless you change management to the highest ranks and empower people at all levels to make things better. Sadly that rarely happens in big companies; people manage to claw their way up and they're not going to risk that job, power or prestige unless it's a sure thing. Which R&D never is.

Simple, cute solution that anybody can understand: record yourself setting it up.

A video feed from a camera and another from the screen itself. Starting from a fresh system, install the dependencies, download the source, verify the hashes, and run the server. Then show the server response from another machine.

Sure it doesn't guarantee 100%. The OS image could have been tampered, or you mucked with the network and intercepted requests. But it's easy to record, easy to understand and much more secure than a black box server.

> Own the robots

Assuming the following generalization is true:

(Energy + Material) → (Human + Time) → Yield

...and that this monadic generalization can be referred to as “Transmutation”, then:

(Transmutation) → Yield → (Transmutation) → Yield → (Transmutation) → …

...is also true, forming a transmutation chain.

These transmutation chains intersect upon world lines, forming trade networks. Humans currently have a monopoly on the transmutation process, and thus, all subsequent structures that process allows. That will not always be the case.

The industrial age increased the energy, material, and yield of transmutation while also reducing time. It also increased the speed on which yield is passed to the next transmutation process by while increasing the chain length. The overall network expanded because of these contributions. The fundamental human component remained the same, however. The delays between transmutation and critical bottlenecks of yield distribution in this network are where financial institutions reign.

With robotic transmutation, the energy variable changes dramatically. “Time value” is no longer a required energy input. Robotic transmutation has no concept of time, and thus, has no valuation upon it. This is not because the robot can't measure time, but because the humans that need the robot isolate the effects of time and decay from it. If the robot breaks down, a human fixes it, not the robot. Therefore, as long as the human/robotic symbiosis remains, the robot will never evolve to resolve the pressures of time value. Therefore, robots cannot establish the skill sets to manage time value pressures.

Humanity, for the foreseeable future according to my theories, will specialize to become a robotic workforces immune system. There will not be a revolt (Sorry social justice junkies, capitalists win again!) because robotic labor will provide access to frontiers previously inaccessible by today's configuration, specifically, deep earth mining and local space colonization.
Ask HN: Do cyber attacks happen slowly or quickly?
Seems like Target etc were hacked over long periods of time. And they slowly leaked data and money.

When they find out about these attacks, they make it seem like one incident where 50,000 people were targeted.

Is this true? Or are these attacks usually incremental and the PR play is just to act like it is a one-shot?

That is a very interesting idea, one that I can relate to.

On the one hand, I do enjoy being around other people most of the time. When I spend too much time by myself, I feel like I am loosing proportion of my own life, like what is good or bad about my life at the moment. Sharing other people's lives helps me keep perspective. Also, a good deal of the time, it's just damn interesting.

On the other hand after a certain amount of time, I also need some alone-time to unwind. And when I've had my share of social interaction, I am happy to spend more time on my own than many people I meet at work.

I've sent him a friendly reminder this morning to please send the payment before he goes so that I can get started on the next set of tasks and I haven't heard from him.

He's a fairly new client and he's sent the first payment no problem, this is now the second and I just feel like his word doesn't mean much... What should I do?

But the pixels aren't arbitrary subsets. Look at it in a single dimension for a moment.

There is a dead-obvious 1:1 correspondence between pixels and lines. You could even label each pixel by its bordering line, and then you're literally counting rationals.

It's possible to construct the pixels with an infinite series of rationals, but it's also possible to construct them as a single rational in a countable way.
Yes. Also, both.

An attack is just a special case of building a computer system. Planning, building, and testing often take a while. Execution can happen very quickly indeed. If you time the attack from "start of execution of final payload script" through "last byte of data transferred by payload script" then many commercially significant attacks were over in milliseconds.
