2 minutes is cute. If you stress a CMS setup hard enough that the young generation is completely full, it will allocate directly in the old generation. This of course screws the full gc heuristic totally, up to the point where the GC is started too late and you fully run out of memory. At which point the JVM drops down to a single threaded oldschool serial GC as last line of defense. On a 96GiB heap, that thing can take hours; all stuck 100% on a single cpu with even signal handling suspended. Fun times.

That said, for heaps above 32ish GiB, we still go with our tuned CMS settings and overcommit one or two additional memory modules. It's a lot cheaper than the time it takes trying to tune in G1 on a large heap with a lot of gc pressure.
The numbers he quotes of "world wide accident deaths" and "do the math" is a totally ingenuous argument. It's nowhere near an apples to apples comparison.

The fact of the matter is, a Tesla driver is not your regular driver. A better test would be to give everyone with a Honda Civic some kind of autopilot.

The data that they do have is a curiosity at best, and cannot be compared vis a vis regular joe blow accident data.

It would be pretty cool, but it would be a lot harder to pull off. At this point the thought of having to be responsible for another server doesn't sound like a lot of fun to me, and preventing users from writing programs that suck up all the CPU cycles is really tricky.

Plus I really want to focus on the storytelling aspects. Especially the end-game scenario (see spoilers/readme.md if curious) would be extremely problematic to implement in multiplayer.

Hillary violated it on a technicality getting work done. Bad for sure. Snowden gave most of the systems and techniques NSA uses to compete with foreign nations and intelligence services to foreign correspondents for mass publishing. It's a nearly 100% different situation. Even if Hillary was punished, which she should be, he would have done something far more severe additionally with provable intent to expose it to foreign parties.

So, yeah, his foreign leaks are still worse than hers. If it was Hillary, I'm more for imprisoning her over track record of corruption and things like torture situation.

The traditional argument against hiring senior people in a young company is usually a mistake because cash is precious and senior people are usually too expensive to fully utilize since at a startup everyone ends up having to do bitch work anyways, so it might as well be cheaper hands doing it.

Senior people aren't always old.. this has nothing to do with age discrimination

I'm not sure I understand how that distinction changes anything. You outright dismissed the project and any of it's potential merits on the grounds that it only promised to be FOSS eventually instead of initially.

Ideals are great to have but you can't dismiss something of merit simply because it's less than ideal. Ideally all medicine would be free and open source but the fact that they're not doesn't mean we should be turning our backs on them.
This is the real problem of VR right now. Content is much more expensive to produce than it is for the written language, music, or film.

Games are the one thing that takes equivalent development effort as VR.

The first billion dollar VR startup is probably the company that makes it cheaper to produce VR content.

No. Not going to happen. The wall, the plain white-ish surface, has been a thing for thousands of years. I own a nearly infinite number of nails, glues and other fasteners to affix thing to my white walls yet change the appearance of my walls ... well basically never. It would be moderately cool to see a wall capable of HD television, but the physics of ever doing, in comparison to a dedicated device, will never be practical.

Sure, poop is not same as shit as per the same lawyer.
I agree. I think that for most people, the key to taking weight off and keeping it off is to just keep your stomach full with food that is moderately low in calories. That means a lot of fiber (fruits, vegetables, beans) and moderately-fat protein, and staying pretty much away from refined carbohydrates and alcohol.

The book The "I" Diet by the noted nutritional scientist Susan Roberts has detailed instructions about how to go about this.
I heard about 0x10ᶜ after I had been working on Bussard for a while. There are similarities, but they are accidental.

I may end up having an assembly language in the game, but it would be one of many languages rather than the only one.

It might take 20-30 seconds to run through all the steps in ones mind, anticipating problems before they arise.
Tesla is pretty clear with users that auto pilot is little more than an advanced cruise control feature and you can't rely on it. The whole Auto pilot name is just marketing. It is really no different than a Mercedes with the same features getting in a crash. As these systems are widely deployed people will continue to die. What's important is that the deaths per million miles is lower than with auto pilot off, and that's already true today's.
Admittedly since children cannot vote our government will always be biased toward the interests of adults and will operate on a time horizon that steals from the future to benefit the present.

However in a utopian version, perhaps there would be some mechanism by which the longer-term interests of children could be represented democratically.

I would also argue that in a capitalist utopia there would not be things that we typically call market failures, since institutions would emerge to solve the problems based on market incentives.

Also, I'm not arguing that a capitalist utopia could exist, just that it is sometimes useful to offer contrast to the idea that big firms must somehow have an enlightened and altruistic vision in order to make investments like the one in the article. It could in fact just be the true north of the profit motive animating longer-term planning than we typically see (due to perverse incentives that focus most businesses on very short-term planning).
Without regard to the original crimes, I think the pre-trial confinement and other conditions were not what I'd expect from the US Government -- I'm in favor of any detainee, particularly a servicemember, being given the level of care and access to speedy/fair trial guaranteed by the constitution. This wasn't met in this case.

I hope she endures and is eventually released early -- taking the conditions pretrial and post-trial into account as a substantial mitigating factor.

As a real world analyst, I'd love a job where you just sit there and pay me to come up with "insights/deliverables" and not have to worry about implementation details.

Indeed, in my experience, the thought that this is how it's done/what analysts should do is a chief complaint about academic-esque analysts, because they can't actually implement anything or their solution is completely unworkable for real scale/tech environment/software stack.

But I would happily take a job where I can be paid to live in my ivory tower if you know a place that views that as the deliverable of analysis :p

Yup we do this, and yes, the verifier has been broken before (during early development, not at production scale).

We do a number of things here, like taking down a sufficient number of storage nodes in a single region to make blocks appear "missing" in the region and force an automatic failover to the other region (this is transparent to users, apart from slightly more latency), or more direct/risky checks in our Staging cluster (we don't ever mess with data in our main production cluster).

In reality a large system like this regularly encounters timeouts or failures of sub-components which are masked by our multi-region redundancy but show up as spikes in the verifiers. These remind us that everything is working, in between more explicit DRT (Disaster Recovery Training) tests.
Similar story: I backed the oculus kickstarter and one of the first thing I wanted to try it once it would be released is realtime 360 video (then move on later to realtime 3d 360). Not being in the Valley, obviously got zero funding, and now such cameras are commonplace; so frustrating.
Sure. "Silly" is in the eye of the beholder, of course, and I do think successfully executing the "launch" of an exploit is probably a great career move.

I still think it is silly.

I'm less convinced the trend has any use for communicating seriousness. I don't expect product names (basically what this is) to meaningfully convey actionable information in any trustworthy way. But I'll reconsider next time I see a car named "Cheap, mostly-OK vehicle with probable future maintenance headaches" or an exploit named "Smasher of stacks of a little-known utility optionally installed alongside Enterprise Product X, so long as these 7 unlikely preconditions are met".

Is iOS first development the right strategy?
I know a few people who run IoT startups. When creating a new version of your piece of hardware involves shipping the designs off to China, getting the hardware back, checking that it's correct (repeat until actually correct), and then pulling "Yes, mass produce" ... before you even have anything consumer facing.

Basically, each "iterate" takes a few months and many thousands of dollars. Lean kind of stops being all that lean.

Lean is easy in software. Thinking before doing is important in hardware.

Basically, the Clintons are waist deep on all kinds of dirty business. It wasn't just her personal email that were in that location or on that server. Other reports connect their Foundation, various staffers, and so on to those I.P.'s. The thing is that people like them like to be in control of their activities and secrets. They might think, absent Snowden leaks or something, that just having their people possess, host, and control the email achieves something to that regard. Maybe it even did.

Further obfuscating their schemes, being control freaks, and convenience all together are my theory. Fits their prior activity.

Ignoring the possibility for compression, read "cost" as the cost of executing a procedure on many instances at once. The cost decreases if you have control over data layout. Think sorting / searching, cache efficiency, SIMD.

Didn't they just leave 300+ servers at a datacenter?
You're right. However, VR-native tools for creating 3D environments are going to be vastly easier to use than desktop based ones (so much of the specialize skills required for using e.g. Maya are just because you're using a 2D mouse and a 2D screen to interact with a 3D world), so I feel that this problem will get quite a bit smaller (though not disappear, of course).
I think your theory is right. If we wanted drama, that's every corporate media outlet right there waiting for us. If we want insight, better chance of it being on places like Hacker News with filtering out the rest. I comment a little on these threads but mostly ignore them.

Also, thanks for HN replies if I haven't said so. Kept me from missing two things just today. :) Btw, are you same guy behind Cyclone or different Dan Grossman?
I worked on the Mercedes system and have driven it for thousands of miles. How the systems approach enforcement is entirely different. If you remove your hands from the wheel for more than a second or two, the system turns off. I can watch dozens of videos of people with their hands off the wheel of their Tesla while speaking into a camera on YouTube. I consider that very different.
There's a lot of harsh commentary, but I think people here are missing the point. The fact that so much software needs root access to a (often mutable) global environment in order to properly build is a bug.

There are an increasing number of build systems that encourage squashing these bugs. The resulting build outputs are simpler and are often more portable. They're also easier to reason about. That translates to simpler deployment, simpler operations, and fewer edge cases to debug.

IMHO, the most promising answer to the 5 minute limit is finer granularity and better caching of dependency inputs.

> That is the only perspective that matters because the p-value is being used as the actionable statistic in the end.

You're obviously entitled to your own perspective, but extracting the t-test from the rest of analysis like that is...idiosyncratic...at best.

Forget about all the MRI stuff for a second and imagine we were working on a grocery store self-checkout system. As you scan your purchases, it weighs each item and tests the weight against some distribution of weights for that product. If the weight is way out in the tails of the distribution, a human checks your cart; this keeps you from scanning some carrots while stuffing your cart with prime rib.

The checkout computer will occasionally flag a legitimate purchase. Perhaps the customer found an incredibly dense head of lettuce[1] . I would call this a false positive: the z-test (or whatever) is incorrectly reporting that the sample is drawn from a different distribution.

Now, suppose that the scale incorrectly adds some weight to each item. Maybe the sensor is broken or a bunch of gunk has accumulated on the tray. As a result, the checkout system now flags more legit purchases for human review. Are you actually refusing to call these "an increase in false positives", since the z-test is working correctly, but it's been fed a database of accurate weights instead of "item weights + gunk weight")? How about if the item database is wrong instead (e.g., chips now come in a slightly smaller bag)?

Or, here's a purely statistical version. Suppose you fit two linear models to some data--one full model and one reduced one--then compare them via an F-test. However, the regression code has a bug that somehow deflates the SSE for the reduced model. I would say this procedure has an inflated false positive rate. You seem to be saying that this does not count as a false positive: the F-test is doing the right thing given its garbage input.

> Any other perspective is the perspective of someone who is confused about what hypothesis they are testing.

Again, this almost makes sense from the perspective of the t-test, but that is a bizarre perspective to take. A MRI researcher wants to know if the BOLD signal in a cluster, once corrected for various nuisance factors, varies across conditions or not. That ("or not") is a perfectly reasonable null hypothesis.

If the corrections are imperfect, it doesn't mean that fuzzy thinking lead them to choose the wrong null hypothesis. At worst, it means that they were too trusting with regard to the correction (but let's not be too hard on people--this is a hard problem).

You're answering the wrong question. They're asking about passphrase for SSH key not OS user accounts.
