> Anyone knows what the "CPU(cores)" means exactly (e.g. 83m)? What's that m unit?

Not sure of the unit, but it generally means 83% of a single CPU's processing power. My understanding is that this is not strictly enforced, it's just a tool for Kubernetes to schedule pods and to make sure no set of pods add up to more than 100m on any CPU.

Well that never happened. It was deprecated with the intention to remove it, but they backtracked: https://bugs.ruby-lang.org/issues/5400#note-25
chroot is a layer in the security onion.

Like every other layer it adds security but isn't perfect. Security will never be 100%. If you want more security, then likely you want another layer in the onion.
I went to a travel medicine clinic, and got two shots.

The cost for the shots was ~200$, and ~300$ for consultation, which was a PA giving me printouts about information of what diseases are found in which countries.

What a scam.

I actually just found the relevant Kubernetes documentation [0]. It stands for "millicores", so 83m would be 8.3% of a single CPU.

Wal-Mart has allowed for overnight parking for quite awhile.

It's even in their corporate Q&A[1]
Q: Can I park my RV at a Walmart store?
A: While we do not offer electrical service or accommodations typically necessary for RV customers, Walmart values RV travelers and considers them among our best customers. Consequently, we do permit RV parking on our store parking lots as we are able. Permission to park is extended by individual store managers, based on availability of parking space and local laws. Please contact management in each store to ensure accommodations before parking your RV.

> How does the animal decide where it wants to seek, or whether it wants to hide? Or what happens when it’s surprised? When it thinks it knows where the experimenter is, what happens in its brain when she isn’t there?

These questions at the end really made me a whole lot more interested in this topic.

And it's interesting to note that she's awarding them with tickles, not food. Could it be why the rats found it to be a more "fun" activity? Would they be having fun or would they become more competitive if rewarded with food instead?

Isn't a big part of the problem that for nearly all of duration of life, all animals had their own excretion patterns? If a monkey eats a banana, and 2 days later excretes nutrients in forms it cannot use... then typically the distance between plant and and dropping is not that far. Plants also spread throughout the landscape.

Birds may perform a larger diffusion work part of the time (random droppings while flying), yet a large part of the time it would eat some fruits from one type of tree, then fly to another type of tree, and leave droppings that represent a mixture of the nutrients the different types of trees had access to, but for a large part what came from trees returns to trees even if it's different types of trees. So by producing one type of fruit the tree can trade it's nutrients through birds-as-traders with other trees. Humans ban birds from trees because we want to keep the fruits to ourselves.

Perhaps we are simply wasting too much of our faeces into rivers and the sea? and generally disturbing the natural transport patterns (hidden labour) performed by different types of animals.

Migratory birds might trade nutrients over huge distances, which may sound ridiculous since they can't hold their droppings that long, but their bodies in general also contain nutrients, and the bird could die at either end of the migratory path.

Safe string manipulation never exceeds the bounds of the buffer. So negative values are dangerous, as all as any additions that would exceed the maximum size.

Negative lengths are not compatible with unsigned representation.

A system implementing invalid string values must choose a text encoding such as UTF-8 that supports the concept of an invalid character. Null termination is too flexible. As such is simple length prepending.

That's a pretty good list.

I'd like to understand why healthcare doesn't bill using time & materials plus markup. All current pricing seems little more than make believe.

I also don't understand why different people are billed different prices. I get that different providers will likely (hopefully) have different billing rates. But isn't billing different prices for the exact same thing illegal?

>people don't understand just how valuable their data is.

My data isn't valuable. Your data isn't valuable[1]. The data of all HN users is of some value. The data of all Facebook users is highly valuable. But no single FB user has any claim to having valuable data; not even in proportion.

The value is in having a collected, curated, normalized, and cross-tabulated dataset. One that can be queried at scale and with good certainty to accuracy. The value is emergent, a property of the whole graph; it's not merely sum of all the parts nodes[2]. This is one of the reasons "databases" are a separate protected category under IP laws. Come to think of it, the value was created by Facebook, by collecting, managing, and processing the dataset, rather than by users collecting the individual datasets.

We may need a whole separate branch of jurisprudence and legislation, dealing with situations where value (or harm) is an emergent phenomenon in a dense network, not only not attributable directly to any singular node, but also much greater than straightforward sum of nodes' values.

There's a similar (if of destructive value) case for vulnerable "internet of things" / "smart devices". Any singular such device being vulnerable to remote exploit is barely notable. Together, a vast army of vulnerable small "smart devices" easily become a botnet in hands of criminals, with power vastly larger than mere sum of parts. Question arises how to handle responsibility & culpability of vendors (or owners).

While this is a cool concept (especially the suspended, likely over-engineered sleeping platforms), I can’t see sense in the business model with this type of pricing. Cabin charges $120 each way for an 8 hour bus ($240 round trip), while you can get a round-trip flight for less than half that with any of the major carriers ($107 for LAX - SFO, $91 for LAX-OAK RT).

As someone that regularly travels between LA and SF, I would rather fly Delta at half the cost and a fraction of the time. Time is money, and it doesn’t make sense to charge more for an 8 hour bus than an hour-ish flight, especially when the majority of travelers would rather get from point A->B as fast as possible.
NYTimes need to stop these self-help smarter living junk science articles. This article isn't helping you relax, it's helping you become a more efficient worker bee:

"daydreaming — an inevitable effect of idleness — “literally makes us more creative, better at problem-solving, better at coming up with creative ideas.”

So the article is not advocating that we should relax more for our mental health or enjoyment, just that if we do relax a bit, we'll get much more done when we're not relaxing... i.e., "spend your weekends meditating so you'll be more productive during the week".

I don't want this to be read badly, so let me start with stating my greatest admirations for the author.

I have never bought any of the zines she produces, I am aware of that, and I also check them out several times. What I don't understand is why people bought them.

Do you find them informative? Do they help you somehow? Do you find them cute?

I may not be in the target market, but I don't find them informative, they are so undense of information, moreover are very easily available informations.

Really, let me restate my admiration for her and the ability to run a business, but again I wonder why people consume that kind of content.

Can somebody please explain?

Yes, but pivot_root(2) is a far more robust and secure way of doing the same thing. There really is no reason to use chroot(2) instead of pivot_root(2) (unless you are running code on initramfs -- and even then you should do the tmpfs trick that everyone else uses).
That depends, in some people it's resistance first (essentially prediabetes), in others it's obesity first.
Some others develop insulin resistance when even moderately obese, there are a few who never develop it despite being extremely overweight.

The lower insulin resistance, the better the effect of diet, usually.

> IMO the problem is a hand-held smartphone is an awkward AR platform

...doooh! ARKit might be good, but it needs to be coupled with a google-glass-successor. Imo GG was the "nokia 900" of its era, proof that it can be done and there's sort of a market, but worthless without something to make it worth the inconveniences for regular users.

To be honest I'd bet on a social-media experienced company like Facebook or on whoever does a good job at partnering with a social media giant because the only AR applications I'd imagine compelling enough for "average people" will involve social things, like walking around a bar and seeing fb and twitter and maybe tinder profiles of people around you near their heads like game stats, sourced based on facial recognitions from people who set themselves to "open"... will be creepy beyond belief, but I'd bet on a mix of social, mildly sexual, with a dash of gaming thing, like a mix of tinder and pokemon go. Now, god knows who has the chops to pull that one right without getting it too creepy...

Probably not what you want to hear, but a framework or guidelines won't cut it if you don't understand the basics of marketing and brand management. Don't take the shortcuts—get a good book, or better take a marketing course. HBR's 'What is Marketing?' is a great intro to the subject [https://www.amazon.com/What-Marketing-Harvard-Business-Revie...] Peter Doyle has a number of excellent books that are very practical e.g. Marketing Management Strategy [https://www.amazon.com/Marketing-Management-Strategy-Peter-D...] or Value Based Marketing.

That's a ridiculous argument. Google has patented way more than this (most recently all kinds of recurrent nets for sequences). As long as these patents belong to alphabet they 're dangerous. Google could have set up a nonprofit for them if they really cared. What if google is bought out in 5 years? What if they get real competition and decide to go full evil?

These patents are overly broad, overly premature. They should never have been granted in the first place.

I think the NN pioneers who are first names in these patents should set up a nonprofit themselves. Hopefully many of them still seem to believe in the ethic of science , having lived decades in which nobody cared about NNs

How about, stop patenting ideas? Stop granting ridiculous patents when it isn't even certain they re the first inventors? These patents are way too premature and dangerous

If the USPTO has trouble understanding a technology, they should err on the side of caution and NOT grant the patents, instead of asking for comments ex post-facto

Take for example Dropout. This is a ridiculous thing to patent. Dropout is essentially half your network malfunctioning. A computer that randomly caught fire could "come up" with the same "algorithm". How can the USPTO judge that patenting this thing in any way would help innovation (that's the purpose of patents). In fact, most researchers will now be discouraged from researching dropout-like techniques any further
The problem is that there are many well-known ways to get around chroot(2) (which don't require privileges). This includes /proc-related escapes as well as more general VFS attacks.

Really, tools should have switched to using pivot_root(2) a decade ago instead of continuing to use chroot(2). Unfortunately this article completely ignores the existence of pivot_root(2) -- which makes it read as though they are trying to convince people to stop using root-switching a security feature (which is definitely bad advice).

Thanks that was quite helpful.
>Blizzard went off the rails by dumbing down WoW [...], appealing to the lowest common demoninator. [...] WoW is boring, unchallenging, and appears designed to provoke the least amount of whining by a vocal but dispassionate player base.

I was around the MMO scene back when Blizzard was developing WoW, and this was the general sentiment around the community even at the time, it was seen as the care-bearest of the all the care-bear MMOs (which is what people at the time called MMOs that weren't hardcore enough for them, particularly in the PvP area). A lot of people that WoW was a step backwards for MMORPGs. At the time MMO developers were doing a lot of interesting things with games like DAoC, Star Wars: Galaxies, Anarchy Online, etc. There was something for all tastes, in particular games like SWG were starting to feature persistent player-build towns, non-combat focused professions that actually made sense to use, interesting skill systems and a more social experience.

At the time WoW felt like a return to the old days of Everquest, only even more simplified and polished (which makes sense since some of the same people were involved). There was even a sort of a competition (more of a shouting match) between Everquest II fans and WoW fans before either game got released as to which would be the future of MMO games. We all know how that fight went.

What I and many MMO fans at the time failed to understand is that WoW wasn't for us. It was for people who had never player a MMO game before. It wasn't an attempt to get MMO fans invested in Warcraft, it was a brilliant move to introduce all the Warcraft fans to MMOs (and the marketing material at the time was very clear about it). It was all designed from the ground up for people who had never even known that MMOs existed, since the MMO market was pretty small back then, and what little there was was pretty divided.

This is also why many people these days have fondness for "Classic WoW," because it was their first, and you never forget your first. Incidentally my first was a pretty shit game called The 4th Coming and I still remember it fondly, while ignoring most of its faults (what kind of casual needs an interactive map anyway, just look at this still picture that roughly resembles the world and navigate using landmarks, much more immersive that way). This is also the reason why all the WoW clones never caught on. The people making them (or changing their game to be more like WoW, looking at you New Game Experience) failed to realize that most WoW players don't really like MMOs, they like WoW, specifically.

Writing this has made me feel pretty old, but I very clearly remember scoffing at WoW players as casuals and their game as an Everquest clone. Here I was playing much better games like UO and SWG and they didn't even know better. Well, time passed and now I'm the one that didn't know better, but I'm still kinda bitter that the success of WoW massively contributed to the death of the type of MMO I liked, and even if it looks like WoWs influence over the newer MMOs is slowly fading, I don't think I'll ever get to enjoy any new MMO the same way I enjoyed the originals.
> We may need a whole separate branch of jurisprudence and legislation, dealing with situations where value (or harm) is an emergent phenomenon in a dense network, not only not attributable directly to any singular node, but also much greater than straightforward sum of nodes' values.

The basic concepts already exist in current jurisprudence, like class actions (many people aggregating together) and punitive damages (damages exceeding cause and effect losses). Don't think these concepts require a sea change, just a modern-day upgrade.

Although I'm arguably pro legalisation I have problems with this. It assumes drugs = MJ, and from observation I'd say alcohol is a more dangerous drug in the way it disinhibits more risky behaviour than MJ - but there should never, ever be use of any drugs, legal or illegal, that can affect someone when they do potentially dangerous work. I think we can all agree on that.

My bigger problem with legalisation is my experience of the utter fucking stupidity that suddenly manifests when drugs are present. Responsible use just does not seem part of many people's nature. I include legal drugs like alcohol in that.

Bit of info, more FYI than actually relevant to the point here, but interesting: a mate of mine works in the office of a largish UK company.

He mentioned that there is drug testing for him and others in the office, at which point I predictably blew my top, assuming it's fucking intrusive American working practices come with American companies trying to spread fucking witless American drug policies over the world (and that is real problem IMO).

Hold on, said my mate, and pointed out that the company has a sizeable workforce that goes out to fix heavy, moving infrastructure under risky conditions. Drug testing is necessary under those conditions, agreed? And if they test them, the company can hardly make an exemption for the office staff, right?

Couldn't agree more.

Doesn't affect me because I have not run Windows for 10 years. I install Windows on every PC. I would prefer to run ARM more wideley, but unfortunately the hardware choice is limited.

That said I am not overly confident that with Linux I am totally immune against executing code I never intended to. The kernel needs to cooperate with the BIOS. I would not been surprised if the BIOS can make it execute arbitrary code provided by the vendor. It just needs to be a bit more tricky than telling the operating system look here is a binary in RAM, please save it on root file system as /bin/init

Right, just like telescope building is about making lenses and hollow tubes, astronomy is about looking at the sky and keying into the functionality that was implemented by telescope makers.

I believe you would benefit from a different perspective because this vision is partial at best. The distinction between who builds system and tools and who uses them is subtle and often these roles are interchangeable. Both have dignity and purpose and contribute to the goal, regardless of the collar color, which is a remnant of the last century.

> How about, stop patenting ideas? Stop granting ridiculous patents when it isn't even certain they re the first inventors? These patents are way too premature and dangerous.

For all the faults of patents (and there are many), one of the great benefits is that when you patent something, you must publish it for all to see. If we want to keep innovation moving along quickly, there needs to be incentives to publish your findings for everyone to review and build on.

The lawsuits don't really start until someone starts making big money. Yes, they are burdensome and expensive, but I'd rather keep innovation moving quickly and having the winner pay a tax than not having any innovation at all.
