Bypassing the operating system and implementing this functionality in user space is already common practice in high-performance server software. From the perspective of a specific server workload, it is pretty easy to design purpose-built schedulers and resource managers that will greatly outperform the ones in your operating system. There is much room to invent better wheels. I presume this software is designed to make that easier, since there are fewer operating system quirks to work around.

Obviously this is not suitable for every programmer (e.g. if you have difficulty designing software that does not leak memory, this is not for you) but there is a subset that can design correct schedulers and robust resource managers in their sleep. The integer factor improvements in system throughput make it a worthwhile optimization if you know how to do it.

> Still, if you rip out the fundamental abstractions of an OS, how would you run an application that relies on e.g. fork? Or any application that runs a shell command in any way?

You probably don't (at least not without removing/changing that part of the application). Unikernels explicitly do not aim at allowing to run a random preexisting application and trade that for the freedom from existing APIs and conventions.

To your question of "Who would pay the shortseller's profit?": in most cases, shorting a stock isn't causing more cumulative loss[1]. There's no additional "payment" or transferred gain. Shorting lets the market incorporate the collective doubt earlier than it could otherwise, but it's the same "payment" (share price change).

One could make a strong argument that shorting prevents some shareholders from taking a much bigger loss. Some shareholders would have purchased in this hypothetical run-up that short sales would soften. When "it turns out this company is worth much less that they hoped and payed for," those shareholders would lose more because the difference between what they paid and what it's worth would be larger.

That's particularly true for the quintessential long-term retail investor who fundamentally believes in the company. That person is likely going to own it until the company's product is proven or disproven, and the fluctuations in between aren't going to affect them (other than as above, if they bought at an inflated price).

Shorting also creates an incentive for skepticism. One could argue that, if Theranos' technology doesn't work, making it harder and more expensive (dilutive) for them to raise money is a service to society.

[1]: an arguable exception is shorting solely to make other investors lose confidence (rather than due to a negative view of the company). However (a) that's not the case here, (b) often it's actually the undiscovered seed of a real issue (someone has to be first..), and (c) shorting enough of a stock to meaningfully depress it is much, much tougher to do than it sounds, since the short investor will need to purchase/repay shares at some point, the possible exposure when they do is unbounded, and they'll need capital to cover their unrealized loss in the interim. This is not a trade anyone takes lightly.

Yeah, the thing limiting supersonic/hypersonic/etc. passenger travel is not the technology, it's the economics. There just aren't enough passengers willing to pay the extremely high fares to make fast inter-continental service work.

Also the precedent of Concorde is not particularly encouraging: building a supersonic airliner required sacrifices of cabin space and comfort which didn't align well with the preferences of the passengers wealthy enough to afford the fare, so given the choice between paying 5x the subsonic fare for quick but cramped, or 2x-3x for subsonic but luxurious, those passengers chose subsonic.

The amount of discomfort that seems inevitable for the sub-orbital trajectories (i.e., you get to know what it feels like to be an astronaut during launch, shaking, g-forces and all) that seem unavoidable for fast halfway-around-the-world-in-a-couple-hours service probably would sink it economically as anything but an occasional jaunt for rich tourists who want to say they rode it.

No, the solution in that scenario is "Spin up another VM, and talk to it over socket." That VM could be another unikernel server, or it could be vanilla Linux that you talk to over sshd, Fabric, Puppet, whatever.

It's important to understand the context behind the current unikernel hype: it assumes that you've embraced cloud providers (or at least run your own cloud on Xen or kvm), it assumes that you are building a distributed system, and it assumes your distributed system is built using standardized components. If 99% of software is various combinations of nginx, Node, Python, Ruby, the JVM, memcached, redis, PostGres, MySQL, and MongoDB, it can make sense to modify just those 10 applications to run on bare metal, cut Linux out of it entirely, realize gains of up to 10x in performance (based on the original MIT exokernel papers), and still present the same programming interface to application-level programmers.

Unikernels are not useful to people who just want to hack C on a single box, nor are they useful to giant companies like Google where all of their software is written in C++ with POSIX APIs. But they could save a lot of money for many mid-range businesses who currently host on AWS or GCE and write largely in high-level languages.
I've heard a theory that commercial aviation as a whole has always been unprofitable. Look at how many airlines have gone bankrupt since deregulation in the US and the removal of flag-carrier subsidies in Europe. Boeing and Airbus are both indirectly subsidized by their respective governments, with each claiming the other's subsidies are somehow unfair.
Marketing spam submitted by the creator of said marketing spam.
IIRC, Rotterdam had a massive govt. subsidy for going fully-automated, which kind of helps.

I spent 10 years between 1997 and 2009 (took a break for grad school) working on semi-automated tracking systems for ports up and down the West Coast (and other places), including one in Oakland. The recent surge in interest in intermodal container ports sure brings back memories!

My company developed niche systems for tracking container location within the terminal by instrumenting and tracking any crane/truck/etc. that could move a container. Even though longshoremen were still operating the equipment, it helped to have a real-time (and historical) picture of what happened, because planning systems were now less subject to clerical mistakes.

Here's their (sort of terrible) website: http://www.nowsol.com/

These guys pretty much own the market for the terminal-planning systems we fed:

Here I was, ready to rail against this horrific explosion in software complexity, and then you go and say

realize gains of up to 10x in performance (based on the original MIT exokernel papers)

Is that true? Do the observed improvements in the field get anywhere close to that theoretical boost?

If that's true, then that's incredible. Which layer of the OS is responsible for an Nx slowdown? Where N is whatever the real multiplier actually is most of the time.

(Aside: it's probably not a good idea to imply "high level language == doesn't use fork." Fork is a fundamental primitive. There are things you can do by forking which you can't do by other means. I mean "can't" in the same say as "yes, every language is turing complete and so therefore can simulate any other language, but you can't write recursion in BASIC, because you wouldn't want to try.")
Very true, but in principle it's possible to completely characterize the downscaling process effected by a physical camera.

To avoid the "bet the company" issue, maybe the future of new aircraft designs will be to create a company specifically to design and build one new aircraft. That company will have a management and marketing agreement with the aircraft company that created it, and will issue equity and debt to finance the design and build. Most of its staff will be on secondment from the "parent" company, and it collects royalties on the eventual aircraft sales/leases.

Did you notice that even sharing the median 2 or 3 BR apartment doesn't work on the so-called "living wage"? To make the argument that people making a "living wage" should be supported by someone in order to have the privilege of living in SF is paternalistic at best and borderline ridiculous at worst.

My argument isn't that people making $14/hour should be able to live on their own; it's that we shouldn't call $14/hour a "living wage" unless it enables someone to live on their own (or, at least with roommates).
The worst sort of business is one that grows rapidly, requires significant capital to engender the growth, and then earns little or no money. Think airlines.

Indeed, if a farsighted capitalist had been present at Kitty Hawk, he would have done his successors a huge favor by shooting Orville down.

"Running a Java program is slower because it has this whole extra step."

Seriously?
This is a perfect example of why most people should not run their own hardware. Don't get me wrong its really fun to build and configure your own server and I openly encourage people to learn but I also remind them that its extremely difficult (for a novice) to do securely.

Additionally connecting a misconfigured server to the internet doesn't just hurt the server owner but the entire network is affected, as you are providing another piece of hardware that malicious actors can use to execute their attacks.

A lot of MIT OCW courses have all of those aside from the autograders, but the reason I prefer OCW to Coursera is because OCW is self-paced.

Many Coursera courses move very slowly (not their fault since they're taking thousands of students), or move too fast and have too much "homework" for a 9-5er. What's worse, some don't let you get ahead! With OCW I can set my own times and pace myself for my kind of learning.

I also prefer college lectures and books to Coursera lectures. Like you said, Coursera content can be too simple.

In computers, when you are working and faced with a problem, usually the easiest thing is to add... add a parameter to a function. Add a member to a class. The nigger loves to add shit. A white person fights tooth and nail to keep it simple.

When it's done, the more complicated design gets the most respect.

Any genius can make it complicated. It takes a supra genius to make it simple.
You're right that I could get just as good results with other potentially faster algorithms but those algorithms don't afford me the ability (especially decision trees) to personalise.

The system is designed to be personalised. So for example if it's not doing well in recognising your squats for instance, you can immediately 'show' it what they look like. A neural network can immediately integrate that, and spit out great accuracy levels. Whilst i'd have to reconstruct a decision tree each time.

Fork is not a language feature though, it's an operating system feature.

It just so happens that it feels that way because it's so universal in multi-process systems. The reality is that there are many uni-process systems, like embedded microcontrollers etc.

Unikernels actually have a lot in common with these sorts of environments. For instance if you are running a unikernel on PV Xen or KVM you have direct access to the paravirtualized network and block device buffers, avoiding additional context switches when doing IO (this is where those 10x speedups from from).

Thing is though you can achieve the same performance on more traditional OS + multi-process setups too but it does require some level of device level virtualisation + isolation and kernel bypass. For instance combining PCI SRIOV with say PF_RING would give you effectively the same performance profile without sacrificing OS level features.
I am in the middle of writing directed pick/put module for a warehouse. I just had a meeting last week on the exact same topic. My software gives the user the most optimal pick list and the warehouse manager wanted me to change it so his team could pick from alternate bins. His justifications:

1. My software doesn't know that there is a cart/ladder/forklift blocking the most optimal bin while the bin next to it is easily accessible.

2. My software cannot tell if QC is in middle of sampling or if Inventory team is in middle of cycle counting that exact bin.

3. My software doesn't factor in changes in real-world that have not yet been inputted into the computer system. So if there is spillage, quantity, or quarantine issues that haven't been scanned into the system yet, my software calculates the optimal bin incorrectly.

It's not that code cannot calculate what optimal means given a set of requirements. It's just that the end-user might be in a better position to decide if it really is optimal or not.
I ran a machine in a colo for almost four years, public facing web server for a dedicated webapp. I managed to escape any attacks or infections, but I'm positive it was 80% of what I did and 20% that it's a low volume app that never got attention by malicious actors. And I've been in the industry for a long time, not a noob.
So I googled it, and for Germany there seems to be a mean cost of 118,000 € per student for the whole degree.

It is very different depending on degree and also university. Medicine is very expensive and half the money goes into educating doctors.

The cost per year per student ranges between 5930 € and 12,170€ over the Bundesländer (counties), maybe depending on the degrees offered? [1]

I found a number for the average cost in the US at US$36,564 per year [2], which today is 32,199 €. So, for Germany, it's about a third per year on average.

edit: Is the US tuition the full cost?
