I'm intrigued by this product, however as someone who can sleep comfortably with earplugs, but find in-ear headphones to become uncomfortable after a couple hours, I'm not convinced.

I always thought the ideal product would be a comfortable, soft armband (think sport sweatband) with bluetooth and a vibration motor. This could be paired to the phone with an app similar to these earplugs, and then used with (or without) regular earplugs for noise dampening. Does such a product exist? Perhaps the Hush folks would consider making it as product number 2?

You've been around long enough to know exactly why you're being down voted, and to know that it's not some conspiracy. Here, let me help: "off-topic". If that doesn't work for you, try "thread hijack".
NextStep was based on earlier BSD, but it was extensively reworked as OS X.
Can you not `func(foo){}`? Because that is what would bother me.

`func(foo){}` and `(foo) ->` seem too similar, for my taste at least. Sure, the difference is that one is always anonymous, where as one is sometimes anonymous.. but we've been using `function` as both named and anonymous for ages
best reliable technology capable of withstanding 10 years in ~ absolute zero while being bombarded with radiation? I'm pretty sure they would still need technology that was "best reliable tech" many years before the launch (and had been tested in space).
I usually describe the body/mood response from DMT as similar to that of some mellow MDMA (without any speedy additives).

When it hits me (DMT) I feel a warmth spread throughout my entire body. I've done DMT somewhere between 300-500 times, though it's been years now.
Yes I think you're beginning to understand the point.
I have numerous times. They come in varying degrees depending upon how much you smoke and the manner in which you smoke (its a bit tricky to figure it out at first). The first "level" (if you will) is a sort of cartoonish kaleidoscope of cards or images, almost 2d. The second level is when you loose the notion that you are on your couch; the experience becomes totally immersive and "you" can no longer be separated from "it". People describe it as a room, but this description is far, far, far from accurate. The third level is when you quite literally come in contact with some kind of extraterrestrial or extra-dimensional entities (these are the only words I know to describe what they are). They seem to be infinite in number because no experience is ever the same, with each contact being immensely different. One common theme however is telepathy; communication most certainly takes place, but it is not with words. Its like immediate meaning and understanding without the limitation of time. It has happened to me during every single encounter and has led me to have a much greater understanding of post linguistic possibility.

Another thing I would like to add is that DMT is the only psychedelic that I know of (maybe mushrooms can hit this place at certain very high dosages) where open-eye reality can be completely transformed, when looking around you are no longer laying on your couch but in some kind of pod and the pipe you are holding suddenly contains a beautiful jewel and is embroidered with some kind of alien language and where, with each subtle movement of your eyes the pod you find yourself in transforms into different shapes with different panels, each wired to your optic nerve. Holy fucking shit people: what is going on out there? More than meets the eye. Its remarkable and weird and beautiful and scary and the greatest of mysteries.

Apologies for the total insufficiency of my words. Everyone -- everyone -- should try it sometime, and particularly atheists and general skeptics. Your faith in your own certainty will be dismantled immediately and forever. The experience is anything and everything but a mere hallucination; its like turning the frequency on a dial and suddenly hitting some kind of super powerful organic SETI message that knows you are going to arrive.
I managed to make myself sound like John Belushi's bigger roommate ... Definitely not true! But thanks to the surprising number of supportive comments.

I think what attracts me is the coherence of a real course of study again. I learn something every day but it's across economics, option pricing, handling profilers across threads, whatever is on fire or on the reading list this week. the subject matter and themes are there but I have to reach for them. It was nice reading through the text and thinking the hard work had already been done I just needed to follow on.

But thank you for commenting - probably biggest response for a while and very inspiring.
Agreed and that's how I've always seen it as well. But when my friends expressed surprise at the obligation, I realized it may not be as clear cut to everyone as it has been to me.

Or I guess to put it another way -- the obligations exist whether we recognize them or not; maybe the value here is in practicing the recognition of the obligation vs. the creation of it.

I think their long term objective is to make it in a separate app. Snapchat doesn't have any logs (it's against its principles) and you would want to have some kind of logs if you're sending money. But launch a product through your already successful product and make it something apart when it gets traction.

I wouldn't let it anger you. I care about quality but every for-profit-company development team I've been on, I was forced to hold my nose at some point/many points/constantly due to some feature demand(s) that had nothing to do with providing a higher quality product and everything to do with either a customer and/or a manager that was a complete and total moron.
XNU really is a hybrid kernel. On the top level you see mostly FreeBSD which as you say brings in the VFS, networking, most of the userland and lots of other things you see in a POSIX conforming kernel. However, many things are actually nothing more than just shims down into the Mach part of the kernel, which brings the virtual memory, processes, thread model and other “low level” stuff. Processes for example can be worked with as if they were a FreeBSD flavoured process, but that will just call down into a shim which calls down into Mach. You can however also work with processes the Mach style, eg. through ports and mach_msg.
5-meo-dmt is a completely different beast than N,N,DMT.

For one, while 5-meo-dmt is endogenous to many organisms (Bufo Alvarius/Colorado River Toad/Sonoran Desert Toad being one of them) it is not found in the human brain.

It's also said to be more intense in an uncomfortable direction than DMT.

> I don't really see a need for square to extend a rectangle.

Except that a square is-a rectangle! Especially in terms of geometry. So you should be able to use this isomorphism in a type system as a perfect isomorphic mapping this is the entire purpose of the Liskov Substitution Principle. But the polymorphic result doesn't work polymorphically in a way that helps people reason about how the system works. It does things that are "correct" from a LSP and static typing system POV, but isn't helpful.
68 hours was the lander's initial battery life. The solar panels were to recharge the batteries, and the expected operation was up to 3 months. The expected hard stop is March 2015, when the comet's orbit will take it close enough to the sun that the tech is not expected to survive the heat.

Rosetta is also equipped with solar arrays.
I like that mercedes is trying something new with this, but I feel really bad for the kids who's parents sign up for this regularly.
You demonstrate what you care about by how you spend your time and money. This is just one more way for parents to ignore their children.

the privileged people in the Bay Area are the ones who can pay for this service. that's what privilege means.

Nobody is claiming this is a charity, or something for the public good. It's a money-making service one step below chauffeurs for rich kids. Why is it something to get angry about?
Just wanted to say thanks, and keep on doing the great work you're doing. KA is one of those places doing good in the world :)
Hm... I don't quite buy that as the whole story. The gcc stuff may all be true (I certainly don't have any knowledge otherwise), but I don't see where it generalizes to clang/LLVM.

Apple certainly isn't wishing they could "get more changes into" LLVM, they're deliberately witholding the extensive changes they have. The iOS 64 bit toolchain is an almost completely closed-source thing, despite being derived from a free software base. If Apple "gave not a crap" about releasing source, they had an obvious path to do so. That they haven't (and that they've invited PR messes like this argument) implies to me that they don't want to release it.
Marshals say there are 94 thousand more where that came from so if you're still scraping together the 100 grand to join the bidding, you'll have a couple more chances.

Sucks to be a child these days. I played with neighborhood kids doing hide & seek, soccer, baseball, ditch digging, crayfish-fishing, arcade, nintendo, bookstore, etc.

Generations of kids grew up that way and they all turned out fine.

What's the point of all these stupid activities we put our kids through these days. I find the very existence of this kind of service very depressing given how rich we are as society.

I think you may be overestimating the complexity of hardening. It's something we do very well. Consider Hubble, manned missions, and also the probes that have journeyed much farther out than Earth's orbit. Hard to imagine that simply upping the image resolution would pose a major hurdle in that arena.

BTW, the solar panels upon which Rosetta relied to make the journey were pretty cutting edge. And Rosetta is the first mission to go beyond the asteroid belt relying only on solar power.

Had they failed, the entire mission would have failed.
To follow up your point: everything we eat that comes from farms (so, most fruits, veggies and meat) has been heavily altered from its wild ancestors. In that way, we very much have, through artificial selection, made food adapted for us to eat.

You are missing the point. The idea is that, as Facebook's and Google's way of managing their large networks become more popular (due to it being more efficient and less expensive), eventually all companies will move towards it. This will negate the need for the expensive Juniper and Cisco switching/router gears which the companies relies on for their revenues.

A sales team is only as good as the product they sell. They can continue to sell a product which is not competitive but only for a while before the market catches up and pushes them down. The effect will not be short term but could be long term (assuming that what article is saying is true).
Alright so somebody with experience in a wide variety of DBs help me out here. Are the enterprise solutions really any more scalable than something like postgresql or is it more that they're more accommodating an enterprise mentality where you'll tend to run into more skill level diversity on the extremes and team A often doesn't necessarily have team B's expertise at stuff? By accommodating of course I mean willingness to take a buttload of money to help teams out with problems when needed and/or to blame when their mistakes explode in their faces and to never ever try to tell anybody that they're doing it wrong once VIPs with enough hit dice are invested in that sort of thing.

I do gather that a lot of DB admins that aren't very political about it do in fact respect MS SQL for some of its more competitive features. I'm just wondering if there's any reason to start with it for a low-cost startup scenario that could ultimately result in a non-trivial but fairly straightforward DB schema with potential for being used by very large institutions (universities at the largest I'd imagine).

I'm ignorant enough (primary experience is in web UI) that I'm leaning towards postgresql because I like the way the Django guys think and they seem to dig it. Also the no-nonsense license and yes, the not-profit-motivated thing is nice when backed by a strong core group which I gather postgres has.

But do the enterprise DB solutions handle severely massive amounts of scale better for some reason? Or is it more that they're culture-friendly to the sorts of companies that typically handle DBs of this nature?

For dedicated server systems that developers don't access, it's pretty much perfect.

While this is mildly off-topic, I'm mildly frustrated that there doesn't seem to be any BSD equivalent to hosts like Digital Ocean and Linode. The closest I've been able to find in recent searches is RootBSD, and its specs are... well, pretty sad for a VPS in 2014. Are there technical reasons that make this difficult to do with FreeBSD? I know you can't use a Linux-specific VM solution like KVM, but is there no BSD equivalent, or no VPS provider with a more OS-agnostic solution?

The idea of toxic masculinity is that it's a set of negative behaviors among men that are reinforced by other men. "Toxic Femininity", if it existed, would have to be a set of behaviors reinforced by other women, so the "disposable male" idea wouldn't really qualify as part of it.

Also, the idea of the disposable male is a bit misleading, because it really only applies to less privileged men, barring exceptions like "women and children first" on a sinking ship, which really is another example of toxic masculinity anyway.
WordPress (and PHP) are not bad things. They are things that have been designed for very specific purposes, and they actually excel at those things. Both are extremely easy to get up and running. They can run practically anywhere etc.

There are entire languages written with the design goal being security. It's not a matter of whether or not something is a capable tool (ie: runs 23% of the internet), it's whether or not it's the right tool for the job. PHP clearly isn't.

Very tempted to harshly criticize at this stage, but let me instead suggest that you take a formal varsity level class in valuations to improve your understanding of it.

> Go model a square and a rectangle in your favorite statically typed language. You will find that square extends rectangle and setting the length on a square also sets the width.

The coordinates of the vertices are part of the identity of a square and in any reasonable model of a square cannot be changed.

An object with mutable size that is constrained to always be a square probably cannot be a member of a class which extends a class representing objects with mutable length and width that is constrained to remain a rectangle (but necessarily a square), since the properties of the former under mutation are not a simple extension of the properties of the latter, so that the two do not really have an is-a relationship (unless the transformations applicable to the two are designed in an unusual way -- as might be the case where the transformations on the rectangle were constrained to preserve the aspect ratio in all cases.)

People often on initial analysis how mutability really destroys is-a relationships which are based on relations between immutable entities.
Best way to get started with SQL?
Hello friends.

I started programming almost year ago and I still very much enjoy it that I've considered to turn it into a career (even though I'm approaching 30 now).
Anyways, 80% of the jobs seem to be requiring knowledge of SQL and relational databases.

Now my skills are still somewhat basic but I'm accustomed to the learning process. I've gone through Learn Python The Hard Way, created my first little program and now crunching through Swift book - so there you go.

My only experience with SQL was using MySQL interface when setting up Wordpress installations. I'm looking for something that is approachable with lots of good examples and possibly exercises.

Is there a good book, youtube channel or course (Udemy) that I should look at?
Mind you I'm pretty serious about it so I don't really mind spending some money (less than $100 though) but if there is good free material, even better! I've had somewhat positive/negative relationship toward Youtube tuts - I found one that was great for Tkinter framework but for Django I had to go through a book to understand it properly.

Thank you!
