In terms of locally-available water, it really pretty much is. As is almost all of the U.S. starting a couple hundred miles west of the Mississippi River and the Pacific, the Northwest excepted.

San Francisco itself has next to no indigenous lakes or (fresh)waterways. Lake Merced, Laguna Honda, and Mountain Lake. A handful of springs. Already in the 19th century, water was in limited supply and brought in from the Peninsula. Much of San Francisco (the Richmond and Sunset districts) were sand dunes. The part that wasn't was in large part wetlands (Marina, Financial District, SoMa, Bayview).

Rainfall ranges from about 12 in (30 cm) in a dry year to about 30 in (75 cm) in wet, but that's strongly concentrated in the winter months, meaning you need a large amount of water storage for the summer (and, again: no lakes).

If you look at a population density map of the U.S., or one with higher levels of detail showing urbanisations, you note that the pattern devolves from very regular in the east to almost a desert-island scattering in the west. Much of that is accounted for by water availablility, and the water shadow of cities. Look at the map below, which shows the Colorado River, and realise that Los Angeles's watershed reaches very nearly to Denver. In many ways, it is effectively preventing any other cities from emerging throughout that region (not that several haven't tried).

Its a valid way to go, but does skip locked handle retries for you? There's more to a queue than just the message.

Also worth noting, postgres is also another piece of infrastructure to run, and not all applications use it.

> If we were immortal, the birth rate would decline

Would it? In modern, low reproduction societies the dominant interpretation of the universal "honour thy father and thy mother" focuses on care. Even the slightest resemblance to a chain of command that might be present earlier stops at adulthood. But with people forever overshadowed by their undying ancestors, we might see a massive resurgence of the competing interpretation which sees it as a natural power structure. If that happens, well, welcome to pyramid scheme hell.
Welcome to the real world. How to integrate an application with “lazy” APIs
Err no. Whoever came up with this idea should simply be taken outside and shot. Actually whoever allowed it to get to this state of development should be shot. The ideas guy and the worker bees are just doing what they say.

There is nothing good that could come of this. Nothing even slightly at all.

Event Delegation: Pattern or Anti-Pattern?
Agreed. They have no quality control over their own deliveries. I live in a multi-tenant building and in my experience Amazon deliveries are hilariously unreliable. They have a hard time gaining access to my building and usually just leave packages outside where they are very often stolen.

The only way deliveries will work for Amazon without the use of drones is if they open up the delivery service like AWS so that other businesses can use it. The reason I believe that is that deliveries need to be reliable. In order for them to be reliable you need to have regular drivers, ie, full-time employees who drive the same routes everyday. But Amazon doesn't deliver nearly enough packages for that line of business to make any sense whatsoever, so the solution would be to let others ship via Amazon deliveries at a lower cost and faster rate than UPS, FedEx, or USPS and perhaps subsidize the losses from other lines of business or raise the price of Prime to offset it.

Ultimately, Amazon is trying to compete with USPS in this space, not FedEx or UPS who want no part of last-mile deliveries.
Scipy+numpy made it possible for me to mostly stop using the various weird, usually proprietary and often highly specialized data analysis applications that are entrenched in the scientific community, and work with a nice, general purpose programming language instead. It was wonderful!

This is close to a decade ago, it kind of blows my mind that only now scipy 1.0 is released. Not that it matters, I'm still a user, thanks team scipy!
I have remarked that people from China always use the close door button. At first it weirded me out because I always waited for the door to close.

In my apartment the close door button is a trap because one has to hold it during the whole closing door procedure and maybe 1 second more, otherwise the door will open. It usually results in more time lost than if one just waited for the door to close.

I recently bought an HP laptop which has a AMD A10-8700P APU and was very surprised to find out that basic display functionality is very glitchy under Linux (backlight would flicker, or in some cases it wouldn't work at all). I tried with Debian unstable first, then with Ubuntu (17.04 and now 17.10) and none of the vanilla kernels in these distros worked for me (with the amdgpu driver, ), so I'm now running 4.9.51+ from https://github.com/M-Bab/linux-kernel-amdgpu-binaries (the most recent versions crash when I use HDMI output).

Slack for YC S18 applicants

Why should it be illegal? Are you saying companies should never be bought by another? Mergers and acqusitions are a massive driver of the market so what do you expect to take up the slack?

Profit isn't the only measure of value. Startups by definition are experiments in business models and scaling quickly. Maybe they build something that fails to sell but are still worth something to the acquirer. Remember there are 1000x more startups that fail completely and generate no value at all.

If you want regulation then it should be for the acquirers from getting too big, usually called anti-trust laws, but I dont see what's wrong with people putting some money together to try and make something to sell.

A Windows 10 Home edition costs 145 euros, pro is 260 euros, it's not exactly impulse purchase territory for me.

I never use Windows because I want to, I use it because I have to. So paying hundreds of euros to have the privilege to use an OS I don't care for just because some developer decided not to make their application portable is very hard for me to swallow.

Especially now with the built-in ads, telemetry, OneDrive and whatnot. You're not going to guilt me into purchasing a copy of that garbage fire of an OS just so that I can boot up the odd windows-only application every other month.
In Excel it is both, very accessible and not obvious at the same time.

At the top left corner of the sheet, just to the left of the formula bar, there is a textbox that displays the cell Number (eg. A1). Simply click on that and enter a name for that cell.
sed and awk complement each other, I think.

sed works on a line by line basis.

awk can work on a whole file. Subsequent line operations can depend on the state of previous lines.

Each has its own operating domain and you have to decide which tool is the best one for the task you have in mind.

It's more than just the two for reference. It's either dead or dying at that age for most people. In addition, my 94 year old neighbour is housebound and has leukaemia and just wishes someone would kill him. My grandmother is 93 and she can't even recognise any members of her own family any more and just wants to go to sleep forever. That's more the state of things.

The above are minor and major celebrities. They have a higher standard of care.

Can I receive in-home delivery if I have a pet?

We do not recommend using in-home delivery if your pet can access the front door on delivery day.
It will be very interesting to see if this gets traction.

I would never ever give a company access to my home. But maybe the next generation will not have a sense of privacy at all. But rather accept that mankind kind of grows together into one huge brain.

From my perspective, I wonder: Are there not enough places where Amazon can drop off packages? In my street, all kinds of shops will accept parcels for you.

Are new houses these days built with "drop off" areas that can be opened with an access code?
Outside of mixed urban neighborhoods, is this really a problem that needs solving? I try to have packages delivered to my office for convenience, but still have plenty delivered to my home, where they sit on the front stoop until I get home.

To me, awk always occupied an awkward (no pun intended) spot. Too complicated for a proper single purpose command-line program. Not expressive enough to be in the same sphere as a scripting language like the ones you mentioned. I was hoping this article might illuminate its purpose, but I'm still just as clueless.
That’s just telling you that a JIT is faster than an interpreter. You’d want to compare PyPy to V8 to see how well they can both be JITed.
Lot's of "nope" here. While it's okay in my neighborhood for a delivery service to leave my packages on my front deck, there are many others who would not be comfortable with this. For those people, I see this as a huge draw.
Jorgen Lundman is also a main coder for the OpenZFS project afaik. I've seen his name many times since the very early betas of the OpenZFS macOS port that I've been using back in 2012/2013. I don't know how it's financed, but I'd think it's not just a hobby.

I love amazon lockers, you don't have to worry if some idiot has been or not.

i'd also like to see "don't deliver to my house option", meaning i'll come and pick it up from a depot the same day.
It's also worrying for households that have animals that are not particularly friendly toward strangers. Would the delivery person be able to press charges should a home owners dog bite them?
Lots of options.

My apartment and several in the area, have a concierge, and they’ll act as a “porch” and even deliver it to your door later in the day

Some apartments have mail rooms, some with automated entry based on if you have a package or not

It’s largely a solved problem

> Like what?
Take any norm breaking innovation in the pass 2000 years. Any idea that sounded arcane at its time: Earth is not Flat, its not the center of universe, light is a wave and a particle, etc. Perhaps decision was not the correct word to use, "ideas" would be better.

> What kind of prediction is that?
A prediction like any other. I think we tend to become risk averse as we age, risk averse people don't like changes, without change you don't have a chance to fail, or succeed. If people to live longer I would think that every other stage of life would start to stretch. Take presidency as an example, its a four year cycle. If life expectancy was 200 years, would it not make sense to have presidents for 8 years? Would you retire after 30 years or 60 years?
This has been the opposite of my experience, but that's just an anecdote, go look at the most popular smart locks on Amazon.

I've been using mine for a rental home, and it has paid for itself multiple times over the years by not having to replace keys, not having to call locksmiths for locked keys, and not having to change locks when tenants leave. Why more people aren't using smart locks is beyond me.

Voting in any democracy which has undergone regulatory capture?
Though, as hinted at in the response, there's more to it than you're assuming, such as research to ensure the new signs are understandable.

Changing things "just because" on your own software systems is fine if that's how you want to work. Changing signage that needs to be correct and understandable takes more effort and rolling back is expensive.

I'd much rather see someone take an hour to write a response on why they're not going to make an unnecessary change to something like this, than waste a lot more time and money screwing around updating signage that works as it's meant to already.
I'd say it's most likely that insurers will just consider it falling under the current guest-exemption clause i.e. any damage or loss caused to your home or contents by people you invited onto the premises is not covered.

Truly caveat emptor, unless the retailers themselves start carrying third-party insurance like tradesmen often do.
Question for those more familiar with 4th amendment jurisprudence than I am: if you give a group of strangers access to your home, does that remove your expectation of privacy in that area? If so, does that make evidence against you gathered through warrantless searches of that area admissable in court? Or would it only expose you to evidence in plain view/hear/smell?

My intuition is that granting consent for some action to one group of strangers does not grant consent to a different group of strangers, but I am not a lawyer.

Whale hunting or scale hunting? (2015)
Initially, I saw this and thought it was an AWS service. Then, I realized how bad of an idea it is to allow third-party access to non-revokable private keys.
Nice. mine were initial versions of Lockitron. And then an August(didn't have much patience to test it, so returned it). Haven't tried Yale Z-wave (is it standalone? or is it bundled with a security service?). I'll give it a try when I move next time.
awk is my go-to tool for simple command line tokenizer. Hard to beat:

awk '{ print $1; }'

Other than that... not really. Maybe the advantage would be ubiquity, if you really, really want to avoid Perl.
It was hard to get across concisely, but I really meant something like my beliefs move to some extent. Yes, I verify.
Exactly. There are a lot of well-designed dynamically typed languages which beat the slow four (python, php, perl, ruby) by a large factor. You are talking about unboxing, but most fast dynamic languages rather have properly tagged primitives. Unboxing is not that performant as starting properly from scratch.

For comparison e.g. php has now proper unboxing optimizations, perl6 also. But the properly tagged primitives such as in Chez scheme, Common Lisp, SELF, Javascript, lua or luajit (to cite the fastest) beat these by at least a factor of 10.

Next problem is refcounting, as you can also easily observe with php7. Getting rid of most local refcounting madness led to a speedup of 100%. A proper GC leads to smaller data, faster updates and memory safety and leakfree-ness.

Next false fact in this article: "Python is interpreted rather than compiled".
Nope, cpython has a proper compiler. It translates the AST (a tree) to a linearized list with relative jumps and pretty tight ops and lot of compiler optimizations. Much better than the primitive ad-hoc AST interpreters of php or perl, which still carry around absolute ptrs all over in its ops.
The problem with the python bytecode is that is still too big, compared to the fast bytecode interpreters.
He probably meant "Python doesn't compile to native code, only bytecode". But there the speedup would be max. 2x, not 10-100 as observed with python. So this argument is bogus.

3. "Python's object model can lead to inefficient memory access" Yes, of course. There's no type optimization done. Which should be trivial and the first thing to do. But more importantly is the design of the hook system. E.g. let's compare it to Common Lisp, where you also can redefine any function/class/object or native data structure access on the fly or Javascript which is similar extremely dynamic. These systems have lots of optimizations for the fast general case, but python not. It generally turns down such optimizations.

But how will you know that my product streamlines your innovation pathways if it isn't implied by an ambiguous stock video with a major key piano arpeggio?

It is a bit tiresome, I get the feeling that they are not talking to me however. I imagine they are talking to someone who's job is to get business software approved by the procurement department. A scenario I know nothing about.

I also imagine some companies do far too much across too broad a spectrum to concisely summarise it. IBM can afford to have lofty aspirational corporate speak because they offer such a wide range of business services to such large entities that you probably need to send your guy to speak with their guy anyway.

My favourite kind of product landing page is a one sentence description of what it does, and below that is a link to the documentation. That makes me think that not only does it do what it says it does, I can probably figure out if it will work for me by reading the docs.

Overall though sounding like a luddite, not keen on strangers having a key into my home despite liability on their behalf. If there was a second door with regard to package dropoff that would be something.
See the comments in the original article for the python examples...

The Lisp program is basically this:

(format t "~a~%" (loop for i from 1 upto 100000000 sum i))

The Python code can be made a lot faster by using xrange and also reduce.

But then the SBCL compiler can optimize a type declared version down to 0.07 seconds runtime for the script.

(locally (declare (optimize (speed 3)
(debug 0)
(safety 0)))
(format t "~a~%" (loop for i fixnum from 1 upto 100000000
sum i of-type fixnum)))
