That sounds like a failure of the JVM. You are also putting multiple independent services in the same fault domain.
Can some one explain NPV to me? This is the first I am hearing of this term and wikipedia does not offer an explanation that is intuitive enough. Its odd that the NPV is listed as $40K+ when the actual cost of the car is $90K+.
Talk about a worthless comparison... Auto loan and insurance costs completely left out? (and these are big factors) Depreciation in a high state of speculation? Comparing a top of the line minivan with a mid size car? A commuter/short trip car (imagine big road trips planned around recharge stations) vs a touring vehicle.

I realize there is other cars besides the Odyssey compared, but why so much emphasis put on the minivan comparison? How about comparing as close of a car luxury, feature, reliability and purpose wise?

Because you have to understand the context. For nearly everyone one earth, a computer is a physical tool that exists for the sole purpose of helping them accomplish other tasks. In many cases, the most complex tasks people tackle are those they're being paid to work on. Those people just want a tool that works, that works they way the expect, that is supported and supportable by a vendor and internal IT, and is replaceable with something similar enough that things don't break.

Look, I'm a programmer turned engineering manager and I totally get where you're coming from with this comment, but you just don't seem to get how and why things are the way they are.

Speaking personally, I managed a project a few years ago to replace MS Office 2003 with Libre Office 4.0 (we actually started with OpenOffice but when Oracle acquired Sun and The Document Foundation was created to house the OO.o fork, we switched out of antipathy for Oracle). The mission was to remove MSO from as many machines as feasible, and the decision of what was feasible was, for the most part, left to me. We managed to convert about 20% of users, and these were composed of about 75% machines that never executed any Office app anyway and about 20% of machines whose users were just consumers of files other people created. Only about 5% of the machines converted belonged to creators. We found that most macros and custom formatting and blahblahblah were fairly straightforward to convert to work in LibreOffice, but the UI/UX was horrific, sometimes things just didn't work, and productivity was adversely affected far beyond the cost of the licenses.

We migrated to Gmail and Google Apps from Exchange+Outlook at the same time and saw similar adoption issues with Google Drive ("Docs" at that time -- in 2008). We (I) didn't make the mistake of forcing the issue this time and relied on coercion and organic growth to build the foundation for broad support. Today we are seeing about 1500 Sheets and ~500 Docs & Presentations created weekly (~22,000 users). Most of them still have MS Office on their machine, too.

Because, guess what, the right tool for the job is important.

(another commenter noted the haphazard and often ridiculous release schedule and evolution of RedHat / Fedora, BSD and Ubuntu over the past ten years or so. In my company, the Linux guys are mostly on their own to build their own environment because it became too unpleasant for corporate IT to create and maintain a standard image that worked well enough for most people most of the time. The devs these days tend to prefer Arch and Ubuntu and the sysadmins often run Fedora (our prod servers are almost always RHEL ... because guess what -- support is kinda important to most companies, especially big ones that aren't technology companies and where internal support is often understaffed and underequipped to DIY everything.)

This probably comes off rantier than I had hoped, and for that I apologize. Perhaps I'm just getting to CIO'y in my old age. :(
I hear you about the effexor. The only reason I'm still on it is because of the withdrawal effects. Those brain zaps are nasty!
On #2, the line between recreational and having a positive economic benefit is rather blurry. Many people take drugs to expand their mind or to work through psychological problems which can definitely give a positive economic benefit. Some people just take it to have fun, but some people only take them to help out a problem.
Not quite the same, but these guys are close:

I think you should reread what I said -- I think it needs to be componentized, because OpenSSL does a lot. Plus has a bunch of utilities to do things.

Comparing it to a library that is mostly crypto primitives is not a fair comparison.

Also - I'm still curious of examples of "hacks upon hacks" for my own curiosity. I've been using OpenSSL in a number of projects for 15+ years, so maybe I am used to certain things.
I want a batch notification service. Every 15/30/60/90/configurable minutes (or on request), the service would ping all my communication channels and give me a summary on a page or to a mobile app. I don't have notifications for email/social media because I don't want the interruption but, during downtime, I find myself checking through all the different services I use to see what's outstanding. I don't need the app to interact with these services, just ping via API and return what's "unread."

I tried to use IFTTT to build something workable but the key is getting notifications all at once for everything when I want them, not duplicated notifications when they come in.

I'm willing and able to work on this with someone if anyone wants this problem solved (PHP, JS).
Is she a music fan? Unusually good at pitch, rhythm, instruments, or memory for music and lyrics?

Williams Syndrome is associated with unusual aptitude for music (or perhaps just unusual compared to the other more serious learning difficulties). There are even music-focused summer camps specifically for kids and adults with Williams Syndrome.

In AZ, CA and OR (only states I know for sure) in the snowy areas, reflective markers are placed in a divot removed from the area between the painted lane markings. It works and is not very noticeable when changing lanes.

As soon as you get to the areas where snow is minimal, the divots stop.

I've not noticed other states (WY, CO, NE, KS) doing this.
I have also ran similar calculations in my head. I think what I'd want to be convinced is a thorough analysis from a mechanical/industrial engineer on how much you can expect to save from a fully electric car on maintenance. The claim I've heard from Tesla is that, since there are much fewer moving parts within an electric motor, the car will last substantially longer. While this makes intuitive sense, I would love to see a breakdown of the actual numbers. Gas savings are pretty easy to calculate.

That said, there is one more factor I had considered, for fun. If Tesla continues to deliver more cars and eventually electric cars dominate the new car market in 5-10 years, I would imagine the Model S would be worth an investment as a "classic" car. If you maintained it well, I wonder if the actual value of the car would have a chance of appreciating at a much higher rate past, say, 50 years.
I see the same issues on my MBA
Also, "Not even Tesla has made money from building its slick Model S." Smells like funny accounting.

Interesting.

The Gorge in OR has the sunken markers and I've yet to see one show up missing during the snow season.

Wonder if there is specific method to install and also for applying the snow plow to cause the reflectors to stay in place.

I just think it's nuts that we're upcasting ints to floats implicitly. Explicitness over implicitness is one of Python's guidelines.
I wrote something to bundle "alerts". It was a node application which would receive updates via HTTP-posts.

From there they would be injected into a redis queue, and fanned out to email (daily), a simple HTTP web-page, and xmpp.

It wasn't hard to setup the core. The hard part was pushing notifications into it. I suspect you might have the same problem. Writing a deamon to stream twitter and POST items matching a regexp, etc. Good luck integrating with facebook too!

Most of the pieces are out there, and joining them up isn't hard. But .. it didn't work out as well as expected just because of the integration aspects. That said I have a semi-working system pinging me via XMPP when new blogs are posted, etc.
I was thinking more of sending stuff peer to peer than purchasing something from Amazon! Or a system to help small businesses to do so.

Ah, I stand corrected.

(I had drawn my impression of Mono from https://en.wikipedia.org/wiki/Boehm_garbage_collector#Uses_a... 's current statement: "The Boehm GC is used by many projects that are implemented in C or C++, as well as by runtime environments for a number of other languages, including [...], the Mono implementation of the Microsoft .NET platform (also using precise compacting GC since version 2.8)"... which evidentially is referring to "also" a different GC entirely, rather than a mode as I had thought.)

Do you know of any good resources that explain more about the precise vs conservative scanning modes of Boehm?

I thought I recalled some references to a precise mode available via a "GC_MALLOC_ATOMIC" function in Boehm which would understand all of the contained data to be not-pointers and thus enable smarter handling, but perhaps that's a necessary-but-not-sufficient thing on the road to heap compacting. I'm hitting a lot of dead links looking for more information sadly; hpl.hp.com seems to have suffered a reorganization lately :(

The RAV4 EV is Toyota's California compliance car -- that is to say, in the state of CA, any auto manufacturer must sell a certain % of their sales as zero emission cars. For Toyota, that meant 2300 or so cars. They ended up putting a RAV4 body/interior on top of Tesla-sourced frame, motor and battery back: the $50k RAV4 EV.

It's been a lousy seller. Toyota only sold 26 vehicles in December, so they've got huge incentives. Currently the incentive is $16,000 IIRC. You can lease the RAV4 EV for $299 per month with $3500 due at signing.

I drive a Fiat 500e, which is a fantastic electric car ($199 lease!) but anytime I'm loading up kids and groceries I wish I had one of those cheap pseudo Teslas.

Electric motor fail on average on par with similarly serviced gas engines.

Failure of motor bearings is usually the result of improper mechanical installation causing undesirable forces acting on the bearings, or simply poor maintenance. Bearings should be inspected regularly for lubrication and uncharacteristic noises. Their life expectancy depends on factors previously cited. Most motor vendors typically recommend bearing replacement every two years, which I think will put a cramp in the Tesla maintenance scheme

What really is off-putting is that even if the car is well maintained and even parked. It will brick as from the degradation of the batteries. At some point the owner will have to invest in a new power pack. Not true of gas motors. I have a 66' galaxie in my driveway with its original motor its never had more than an oil and spark plug change and it has a life of nearly 50 years. I'd have bought at least 3 tesla power packs in the same time frame, even if the car just sat there.

There's an important distinction here that most people miss, namely the difference between a 'cryptographer' and a 'cryptography engineer'. A cryptographer builds schemes and protocols and proves their security. (Phil Rogaway is a cryptographer. Bellare, Boneh, Rivest, etc.) A cryptography engineer writes code that implements schemes developed by cryptographers. To be a good cryptography engineer you really need to learn how to break systems. In contrast, some of the best and most important cryptographers never even touch a keyboard except to typeset research papers.
I suspect this would need to be city-wide, or otherwise regional to make sense from a logistical point of view.

But the most likely criticism is the lack of variety. You send somebody food they don't like. e.g. A meat-eater who doesn't like beef, and they'll be unhappy regardless of how healthy it might be. Suddenly you need to let people choose from a menu, and the economies of scale become harder to achieve as you've got to cook N-types of meal, not two.

I don't have business idea. I just want to own one and use it occasionally, such as hiking and skydiving.

I've been hearing rumor about a consumer-level launch after Google I/O. Not sure how I will feel about owning a dev version vs a consumer version.
The intent of the book, as stated by the author, is:

It assumes that you aren't looking for cryptographic
theories, but practical ways to use cryptography in your
projects.

If you want to build a cryptographic library for other developers to consume, it's imperative that you understand the theory behind crypto principles. The author is telling you that this isn't the book for that.
Of course, his Wharton admission was not independent of family status. It can benhard to separate government corruption from general privilege, though.

Ditto here on what you've been doing. Caffeine modulation (I alternate month intervals btw caffeine and nicotine gum).

I have a preference for well understood/studied chemicals now. Previous experiments with narcotics and pharmaceuticals were helpful in understanding dependence/addiction, mysticism, and enlightenment. Those experiments only revealed that most effects are aberrations and the cost+risk+utility of these is a net loss for me. I encourage people to experience this and have offered guidance on managing it - definitely do not try specific ones if you have ever had a notion of dependence or inability to control things like alcohol, smoking, etc. Addiction is not the goal and almost always is a net loss, so be aware of yourself and don't take foolish risks.

My experiments have so far led to net positive, but I am only now about to begin sleep modulation since I have baselines for the chemical experiments.

Basically, balanced nutrition to meet your needs for exercise and productive knowledge and skill acquisition (and relationship building) are foundational. Then start testing augmentation. Keep logs/journals and be open about it with nurturing people around you who understand your life goals, etc. You can also consider your various relationships as variables, so be careful when and how you enter, and alter, relationships while you journey. You need to be able to extricate yourself when you see losses not in line with your larger goals. Developing codependent relationships AND addictions is a dark road.
Actually, there is already (proprietary) multitenancy support for the jvm that provide full isolation (minus JNI calls). See http://www.ibm.com/developerworks/library/j-multitenant-java... .

IIRC I saw some talks about introducing it in java9.
That may be so, but Haskell went through a very long gestation period while Clojure really hit the ground running. The Haskell as we know it today (from the revised Haskell 98 report) didn't come around until early 2003.

I think it's reasonable to disagree with the part he quoted. "A review by a security engineer ..." Well, it was reviewed by security engineers, and the false sense of security remained. The rest seems fine though.

Is this different from Histrionic Personality Disorder?
It comes down to intent. There are two distinct ways to evaluate Akamai's patch:

1. Did Akamai release the PoC patch to start a discussion about how to protect private keys and share their work as a starting point for changing the code? If so, their efforts here should be considered in that vein and any criticism should be used simply to guide the development of a usable and functional patch.

2. On the other hand, if they are supplying this code as assurance that customer keys were properly protected against exposure by the Heartbleed bug and that certificate replacement is not needed, the patch and the subsequent criticism should give Akamai customers pause.

edit: Akamai acknowledges the bug, and has started rotating all customer SSL keys/certificates, per https://blogs.akamai.com/2014/04/heartbleed-update-v3.html
Great points. I've got no problem with practicing stuff I don't understand (that's pretty fun usually).

If they say something should take X hours or less though, and I'd take at least double that, it worries me. Maybe the job is just beyond my skill level right now, I'm not sure.
I'll add: if all this seems too opaque to jump into at once (and especially if you're unfamiliar with Haskell or other FP languages), don't give up on FP!

A "functional" language is not always a "pure" language, and a "pure functional" language certainly does not always have dependent types. These concepts build on each other.

A great intro to FP is "Programming in Standard ML". Concise, precise, and very approachable. SML is functional, but not pure nor dependently-typed (though purity is encouraged). http://www.cs.cmu.edu/~rwh/smlbook/book.pdf

Haskell is like SML with enforced purity, a different module/typeclass system, and default laziness. LYAH is the best intro. http://learnyouahaskell.com/

Idris is aimed primarily at those already familiar with Haskell, so don't be discouraged if the online REPL feels too foreign!
This may not pertain directly to your story, but I feel the need to explain something, as a physically impaired individual.

We, as individuals , live with certain impairments.

These impairments only handicap us when we are put into a situation where our impairment serves to hinder us in some way.

A disability occurs when our handicaps , which were caused directly by our impairments serve to effectively eliminate an ability of ours within a given environment.

Please try your best to keep the wording straight, it can end up being contextually important.

An easy way to remember : A handicap is basically the same concept as it is applied to sports, negative points which serve to reduce the chances of conquering a goal.

As much as I'm drawn to languages such as Go that are designed for ahead-of-time compilation to self-contained executables, I don't buy your claim that dynamic languages are particularly susceptible to degeneration. As others have pointed out, Java and C++ are both statically typed, and they've both accumulated considerable cruft over the decades. Go is cleaner primarily because it's newer.
I just stumbled across that same info, came to post it, and saw your reply.

Stuff like this really makes me wonder about the authors of articles like this. Are they actually so stupid that they think it's reasonable to allocate the entire R&D effort to 20,000 cars sold to date? Do they know better, but are trying to make GM look bad for some reason, and think their readers are that stupid? It's just so weird.

I could just leave it at https://en.wikipedia.org/wiki/Strawman. After all, this is what most people who are talking about "capitalism" are doing: strawmanning it. I guess the problem is that many of us, neo-cons, neo-liberals, classical liberals, libertarians, anarcho-capitalists are trying to defend capitalism, but all we mean fairly different things.
How much does a new electric motor for a Tesla cost versus a new gas motor for a similar car? I'd guess it would be significantly cheaper, but I certainly could be wrong. I don't know that much about cars.

Downvoted an honest question stated in a reasonable manner? Come on.
Beeminder, as others have mentioned, handles #1 and #3 pretty well (minus the donation to the KKK part - the money for failing goes to Beeminder).

I built GTBee[1] using the Beeminder API which is pretty much #2. Again, the punitive thing is taking your money, starting at $5 and escalating from there.

This isn't to say that it wouldn't be a fun project to build things that do this though!

Look at Rogaway's work and see what he's breaking as he designs stuff. Boneh might actually be more famous for working breaking than building.
His use case for the Odyssey must be atypical from what I've seen, that is, it's used mostly for short local trips. What most people I know use their minivans for is that, plus family road trips. Not really an option with the Tesla.
