Python and similar dynamic languages suffer from the fact that every name access (variable, function, etc) incurs a dynamic lookup of that name in a (nested) dictionary. Statically compiled languages don’t have this. There are fairly recent, clever optimisations that can avoid many of these lookups but (a) they are not implemented in any of the common implementations of Python, R, etc (JavaScript has them though). But even with these optimisations in place we cannot get rid of such lookups altogether, and they kill cache locality and branch prediction.

There are other reasons for slowdown (automatically managed garbage collection is a big one, and so is any kind of indirection, e.g. callbacks). But usually the big one is name lookup.
Who's talking about raising taxes?
The German renting market is really interesting. Some reasons contributing to such a low owner rate include, 1: favorable laws in rent control - preventing more than 15% over 3 years (~4% per annum), negating the need to buy to hedge against the risk of huge rent increases[1], 2: the tax policy is structured such that home-owners do not get to deduct things like mortgage interest payments, unlike in the US and Spain, 3: the German banks are inherently risk-adverse and as such have historically been pretty stringent when it comes to lending, 4: in tandem with (3) , there are no government subsidies or programs like the FHA which offers banks the ability to offer mortgages to people with only 3% down.

Just as software wizards are in other contexts, that would be useful for a new user, but frustrating for a power user who knows exactly what they want and the quickest way to select it.
Yes, but peer review is limited by the understanding, imagination, vision, and intelligence of the peers, who are not always peers in such aspects. Sometimes it takes creativity and individuality, as well as a little confidence, to come up with the right solution. But committees are not designed for that kind of solution. They're merely designed to analyze data and come up with a dry answer in conformity with "core principles", which is at odds with the kind of raw humanistic creativity you get when you just say "screw it" and go on a 2 week code binge to write the thing you needed all along. That's why git exists. It could never have come about through code reviews or other types of committees.

It'd be interesting and quite helpful to see the failure rate vs. drive age, per manufacturer.

For example, for less reliable manufacturers there might be a "if you get past first N weeks, you are fine" pattern, or a failure cliff exaclty 1 week past the warranty period, or something equally entertaining.
I read the same thing a year ago and I came away actually upset at the tweaktown article. Off the top of my head, I remember some of the complaints being that the drives were subject to abnormal amounts of heat and that the drives were consumer-level drives.

I remember a study Google did on harddrive reliability and it seemed to show that heat had little to no effect on it. I also don't regard consumer-level as being a bad thing. As a consumer, I kind of want to know which drives are built for abuse better. All drives fail; which drives fail more and at what cost?
Fair enough, although I've always (well, since 1980) been skeptical that an exponent range from 10E-307 to 10E+308 fails to suffice for any real problem. I mean, come on, there's only something like 10E+80 atoms in the universe.
As far as I know byte-compiling won’t actually alleviate the repeated name lookup (or does it?). Unless the R byte compiler is fiendishly clever, every single name lookup in the loop body will still incur what essentially amounts to a `get(name, environment(), inherits = TRUE)` call.

That's not true, certainly not in the south east. The bubble never burst here, house prices have been growing faster than inflation for decades.

Politically it is now impossible to let it burst, so all sorts of schemes are made up to keep it going.

Edit to add: a typical 2 bedroom terrace or end of terrace now costs between £350-500k ($500-700k) here. These are not large homes, don't have luxurious gardens, don't have a garage at all. This isn't even London, this is just outside London in the south east. And wages haven't kept up.

Imagine San Francisco house prices without San Francisco wages, that's why people are talking about a generation of renters.
The idea that ANYONE reads any of these emails is just laughable to me. They are dunning emails sent to drum up support, and they basically get shitcanned instantly even by supporters. They DO have some impact, mainly just keeping the candidate's name at the front of the donor's mind and providing a "donate now" link when they finally get weak and give again. But deep textual analysis is just marketerbation.
It is -however- a >5 year old, fanless laptop with many, many hours of battery life. :)

It's also substantially more durable than the vast majority of laptops out there, due in large part to its chunky construction.

It's a pity that Panasonic failed to choose the low voltage variants of the CPU in the CF-31 (and -thus- had to add a fan into the machine). It's awfully nice to have a laptop with no non-hinge moving parts to wear out.

I'm sure they ran the calculations and decided that electricity is cheaper than sunlight.

An immediate guess would be that with artificial lighting you can stack fields one on top of another. Something you cannot do with sunlight.
You should try to evaluate candidates based on their portfolio, resumes, etc. If after doing so you still don't know enough to evaluate them properly then sure, give them a take home test.

Central to the Innovator's Dilemma thesis is that the company has to be profitable on the low end. The idea is that by going after low-margin customers, it forces them to cut their cost structure to the point where this is profitable, usually by investing heavily in automation & UX. Then when they want to move upmarket, this cost structure is a competitive advantage they can leverage.

Note that successful applications of this theory usually don't try to sell the same low-margin, self-service product to enterprises. Rather, they create a new "enterprise" product, priced according to what enterprises will pay. They get to leverage all the infrastructure, R&D costs, and ecosystem that's already gone into the mass-market product, but then apply that (with some additional features, and usually hardened security & reliability) to beat incumbent enterprise software on price.

Curious which companies you're thinking of - I can think of a few other mass market SaaS companies that have stumbled recently for the reasons you mentioned, but they have other things going on too.
Currently ~6 people have a shot of becoming the president, 4 of them are supported by super-pacs.
Money does not care if the president is dem or rep they only want them to execute on their agenda.
The odds are stacked against the majority of the population.

And if you go one level below the presidential race you can easily buy seats in the house / senate with huge contributions because people do not care that much as they do now.

Overall this is not a problem in the USA alone if you have the media/papers on your side, who are usually owned by a small amount of people/families, the chance of winning an elections grows exponential.

Hopefully we see a change with this election as people realize they are getting gamed and start to research online. That`s one of the reasons Sanders will have a very good chance of winning because you can lookup 20+ year old videos and he is consistent.
I think I read roughly half the emails. Some of them contain news that I wouldn't otherwise know to look for because the mainstream media don't (or are late to) cover it.
Even shorter version of how to stay alive - model your business around some transaction that brings in more revenue than its costs to provide.
> And I hold out hope that "heretofore" herefromaft be considered a fluff word.

The comparable opposite of "heretofore" is "hereafter" (the "tofore" comes from Old English for "before"). And its not a fluff word -- it has clear and specific meaning -- though "previously" is more fashionable now.

It doesn't matter, it's still a smaller fire.

It has to be an absolutely bizarre market for a renter to find an equivalent place to rent, then have enough money left over that they can invest in some mythical financial instrument that will earn them all that rent back plus whatever valuation a property owner is earning while their property appreciates in value.

At the end of the mortgage the owner now only has to pay any applicable taxes and the cost of living is more or less "free" (minus maintenance). A renter will rent forever.

Actually, not that many. There are less than 20,000 commercial flights in the air at any given a time.
The trade offs are present even where I'm living now, long commute times and poor infrastructure even for very new areas (built in the last 15 years) make it harder to get anything done. Even so, in this more reasonable area, I'm spending almost 60% of my weekly income on my house and a further 25% on food and bills.
For R at least some of it is due to R's flexibility

x$name syntax stems from data frames being really lists in disguise
x[["name"]] ditto, plus because it's useful to access by string (see reflection in other languages)

x[,"name"] and x[,1] because we can also apply the matrix syntax to data frames
The problem is that it's far more difficult to prove what code doesn't do than what it does. I can write a function to do X, Y and Z, and I can show, through observation and aggressive testing, that it does indeed do X,Y and Z....but its a lot harder to prove that it only does X,Y and Z and nothing else. Memory safety is just one expression of this problem.

This concisely points out exactly why we never recovered from the great recession of our time.

"I don't read them therefore I am certain nobody else reads them."
As character, for instance (in particular, they can do everything factors can do when used in conjunction with `unique`, and sorted factors can be represented as a conjunction of characters and numerics). Factors work better, but only barely. In particular, they are nowadays not any more efficient than using character (!). They used to be, which is why they are liberally used everywhere in R’s base libraries.
That is a great but that can stop you from producing an Uber, Facebook, or new drugs, a Tesla, an Apple, and more.

UI testing framework for iOS by Google
Ask HN: Simplest way to create a very basic data driven website these days?
Hey guys

I'm not up to speed on the latest cloud offerings out there.

For very simple side project ideas that are essentially static websites with a search engine component that needs to query some data, what is the quickest/simplest options out there these days to get something running in a few hours?

Here's what I was hoping to achieve:

1. Upload a CSV spreadsheet of data to some cloud storage solution

2. Be able to quickly define some simple API endpoints hosted in the cloud to query said data.

3. Write the website as static files with a js client querying the API endpoints as needed.

4. Host the website as static files in S3 or similar for low cost and ease.

What is out there that is similar to this and do people recommend as the easiest to use?

Thanks!

I understand that Sanders' personal emails are on the official government servers, so there's not a lot he can do to affect those. And I expect they're both using Mailchimp or another email marketing provider for the mass emails, so again not a lot they can do. Perhaps we should use their campaign site PageRank instead, as a measure of popular support?

Also, it's "hear, hear", though I can see how your form could be appropriate for text instead of speech. Etymology: http://english.stackexchange.com/questions/6690/hear-hear-or...

> So...you can't have a summer home? Ever?

Reading grandparent post, sure, you could, but if it was in a housing crisis area, the government would be empowered to appropriate it for the purpose of renting it out at rates comparable to non-luxury housing (presumably, with you receiving the proceeds of the rent.)

Clearly, such a rule would need an objective definition of "housing crisis", but the temporary seizure of property with compensation this proposes is actually fairly mild compared to the way critical resources are generally treated in times of genuine crisis.
Sounds like the perfect retirement community for a serial killer.
That's the shoeshine-boy story: "you can't go wrong with bricks and mortar". Coming at the end of a decades-long rise in leverage it's easy to see why people swallow it without too much examination, but the Great Unwinding is arguably upon us, and you're assuming (and ignoring) a whole bunch of things.

> because payments toward ownership build capital

Money invested outside of property also builds capital. Money not spent on mortgage interest builds capital. Money not spent on maintenance builds capital. Money not spent on property transaction-related costs (surveys, legal fees, Stamp Duty in the UK) builds capital. Owning property when a major housing bubble collapses burns capital faster than your wildest dreams. (Not everywhere has a housing bubble at the moment, but an awful lot of places do.)

Obviously you can argue with a lot of that, but the picture is nowhere near as clear-cut as you're making out.
My buddies in middle-America were capitalizing heavily off of both the FHA and the incredibly low interest rates circa 2011 (thanks artificially depressing the dollar, Fed!). They started out with a handsome amount of capital and borrowed against their 401(k) [I don't recommend this] to speculate on the rise of land [I also don't recommend this], threw down 20% to avoid PMI [I do recommend this, if you can afford it] and started renting out properties. They essentially speculated on gentrification, got lucky, and pay a management company to maintain their properties so they don't even deal with their tenants. Their bi-monthly involvement is limited to reconciling their accounts for 20 minutes and a five minute phone-call to resolve any potential outstanding issues with the management company.
Sorry for ninja editing underneath you. I've usually heard "heretofore" used in fluffy contexts, often hanging out with words like "insofar" and "wherewithal", occasionally served with mutton chops.
> Why would you have to be a nationalist to post about China?

Because the guy I replied to said: "Surely, you're more likely to submit a post about your home country"

I'm an American but my grandparents are from Ireland. I personally feel no connection to Ireland nor do I have any idea what's going on over there. It's any other country as far as I'm concerned. I wouldn't post news about the country to HN. However, if I did, I would be a Irish Nationalist. Feeling any sort of loyalty to a country (whatever the reason or justification) is nationalism. It's literally the definition of the word.

I'm not sure that distinction matters for my comment. It may for the study, but my comment was a bit of a tangent anyways.
Metal predates Vulcan by any measure. It was the first publicly available low level graphics API and once they released it that have an obligation to support it. It was released, what, 4 months after aMD announced mantle? That's not enough time to develop and deploy an entirely new API, from my memory Vulkan was more a response to Metal, DX12 and Mantle.

How hard would it be to semi machine-generate such vacuous articles? Would it make sense for the ad value of eye balls? Maybe if such generation becomes common place a shift in value bringing back better curation and editorial lines in social/mass media will occur?
All from (3). Definitely not io bound, and using standard python 2.7 (if numpy had been applicable, I would have used it...)

My data structures for numerics are generally really simple, and generally I'm able to go from python list/dict/sets to c++ vector/map/set pretty directly.
More likely, they committed to Mantle and now they have have to maintain it. The manpower to maintain 3 separate graphics back ends probably wasn't worth it, especially since big portions of the OS libraries now support metal.
The goal is to have a cross-platform low level API that can be easily tested for compliance/conformance, right?
Yes. Go and learn too. And help!
