Purchasing is full of unintended consequences.

"You only get paid if the project comes in under budget" might just only give you the lower-tier players who have no better project to work on -- maybe the more professional people would say 'no way' to an arrangement like that, especially given the % of these projects that wind up running over.

Then you wind up over budget with a sub-par contractor in charge of the project.. what do you do, change horses mid-bay? No way, turns out the threat doesn't even have teeth.

It does help that I'm one of the few people who are paid to work full-time on nothing but open source R packages that a designed to broadly aid data analysis.
> I'm not referring to fixed point, but fixed-size representation.

I'm still not sure what you mean as any IEEE floating point (which in reality all anyone uses) is fixed-size. If you decide to truncate, round, do w/e to this value, you may still not get exactly the same answer for similar computations or even the same computation on different machines. There isn't a reason you can't (well, shouldn't) do float_val == 0.0 -- it won't work in all circumstances.

Please explain your method of making sure float_val == 0.0 while retaining the essence of being floating point (i.e. not using fixed-point).
I wish I knew what this bear was thinking:

http://www.mtexpress.com/news/environment/bear-grabs-sleepin...

"A Boise hunter sustained minor wounds when a black bear grabbed him by the head while he was sleeping in the open along the Middle Fork of the Salmon River last week."

"He said that before the men went to sleep on the night of the attack, they had stowed all their food in a box on their raft."

"Jon Rachael, state wildlife manager for the Idaho Department of Fish and Game, said unprovoked attacks by black bears are rare, and it’s impossible to say what motivated this one. He guessed that either the bear had become conditioned to people by finding food around them or perhaps was just curious, and grabbed Vouch’s head to see what it was."
And then the individuals would grant use licenses to the corporations, so they can implement the process/manufacture the good/etc?
Well, I use both, and I can do everything in Python that I can do in R. However here are some things which will give you a flavour of R's more consistent, data-first nature:

> rollapply(some1000x10matrix, 200, function(x) eigen(cov(x))$values[1], by.column = FALSE) # get the first eigenvalue rolling 200x10 window.
>>> # impossible in Python unless using ultra-complex Numpy stride tricks.

> dim(someMatrix)
>>> someMatrix.shape
> head(someMatrix)
>>> someMatrix.head() # notice consistent function application in R, whereas in Python, mixed attribute / function? So we're on OO land and I must know if it's an attribute or a function....

> rollapply(some1000x2matrix, 200, function(x) {linmod <- lm(x[, 1] ~ x[, 2]); last(linmod$residuals) / sd(linmod$residuals)}, by.column = FALSE) # get the z score in one multi-step function.
>>> Impossible in python without For loop as lambdas cannot be multi-statement.

> native indexing using [] brackets by index number, or index value, or boolean. All vectors.
>>> pandas loc/iloc/ix mess.

> ordered lists (python dict) by default, so boolean or index subsection easy even when data is hierarchical, not tabular
>>> easy bugs due to unordered nature of dicts; must import some different module and then still can't vector index it.

It's all summed up by this:

> c(1, 2, 3) * 3
[1] 3 6 9

>>> [1, 2, 3] * 3
[1, 2, 3, 1, 2, 3, 1, 2, 3] # wrong! Need rescuing by Numpy!

And then there's CRAN. Just last night someone told me about "nowcasting" which uses "MIDAS regression". A relatively new technique. Google it for R (full package available), Google it for Python (Matlab comes up ;-).

And I'm not even going to start on graphics. Seaborn and bokeh are valiant efforts, but they're still 80% of what ggplot and base graphics can do, especially, at the multidimensional scale. That last 20% is often all the difference between meh and wow. That said, I do appreciate Matplotlib's autos rescaling of axes when adding data. Python charts aren't as pretty nor capable of complexity (for similar effort), but they're arguably more dynamic.

Now don't get me wrong. The converse list for Python would be much longer, because it's more general purpose, and it kills R outside of data science. I wrote 10k loc in R for a semi-production and it was horrible because it does not have the CS tools for managing code complexity, and it really is slow at certain things. R is more focused on iterative, exploratory data science, where it excels.
This studio also did the graphics for Mission Impossible which had a similar style:

Overall I agree with you, and I prefer when commenters are respectful of everybody's else feelings. But I don't think it's that bad on hacker news: the ranking system is quite efficient and I often learn something from the comments.
"It's unconscionable that they should cost more than $25-$30 a pair."

Nice. The down-range focus on the fenceposts is very good. Cross-range focus isn't as good, still impressive for a such a low-cost system. It'd be very interesting to see some images of a more target-rich environment.

Radar, SAR, and especially passive multistatic SAR are technologies that I'm sure we're going to see more of in future. Passive SAR (or transmitter-of-opportunity SAR) can be computationally expensive, but pieces seem to be there to build something that works really well.
'I never wanted to be scary': an interview with R. L. Stine
Because of math? This survey is for nearby stars. The star in question is, in fact, only 1500 light years away. The chances we'd observe a rare phenomenon in a small subset of stars (the article says the survey was for ~150K stars) is, according to the authors of the paper, exceedingly rare.

Given the author of the paper is doing a proposal to point a radio telescope at the star says to me that chances are decent enough to justify further investigation.
I completely agree. ggplot is the only reason why I sometimes use R.

Slack is even easier to extend than IRC, and all those IRC bots can be plugged straight into Slack.

A sufficiently advanced IRC client may be able to catch up to Slack in some of its essential features, such as formatted code sharing, image sharing (for screenshots and other things), document sharing, comments on uploads. etc.

But at that point, why not just use Slack or Mattermost.

And IRC is not even close to an adequate solution for what Slack does when it comes to non-devs. If you only ever talk to people who code, then perhaps you can work around IRC's deficiencies. But by using Slack, the conversation can be opened up to all sorts of non-technical people, and it enables them to communicate effectively so much better than IRC ever could. These non-technical people's contributions are essential to the functioning of almost all serious companies, meaning that for most teams, IRC will not work and Slack will.

IRC is a telegram network operating on Morse code compared to Slack's cellular network.

Recognizing that you're accidentally/subliminally sexist or racist is good. But you should also recognize that those have had an effect on the world, and knowingly attone by spending some of your privilege. A sudden self awareness that leads to just a blog post isn't really anything special. A sudden self awareness that leads to action is meaningful.

(before I get asked "what was my action", I'm still trying to figure out how to spend my privilege for others benefit in a way that's more than just donating money to appropriate causes - which I already do. I'm not thinking big enough yet.)
Also, the specific context here was "Given semi-protected sidewalks this design seems to provide equal access to both bicyclists and pedestrians".
I can understand your point, but isn't the answer just "more science"? We want to have a theory based on early data (since there will be a policy, whether explicit or not, so better to base it on our best ideas to date), but it's early and we don't really know what we're doing. Then we get better data and better theories and voila! New consensus, better theory, better policies (in theory ;-).

Maybe advocate more open-mindedness so paradigm shifts don't require extinction of the proponents of the previous theory? Or strive for more policy responsiveness to scientific discoveries (I guess it's pretty clear this would be a Good Thing)?

I think structurally encouraging policies to be built around actual scientific consensus and data (and to keep up with the field) could go a long way.

CF is a regulatory derangement, so I don't know what all else it might be doing and how much it might be relevant to normal type humans.

That said, no one's come up with any vaguely useful citations linking saturated fats to diabetes, and this doesn't help the case for that.
Working with text data in R is painful, but it's not due to limitations of the language.

This was said a little obnoxiously, but he has a point. Making pants in China takes about three labor hours[1]. Given that about 50% of the cost of pants is the retail/wholesale markup, that leaves $15 to pay for materials, shipping, and labor. It's hard to squeeze a living wage out of that.

It is a genius move. Their real estate leases and operations are surprisingly cheap when it comes to brick and mortar because the footprint is so small. And they have completely eliminated the most dangerous and costly aspect of B&M: inventory management. The more stores you have, the more fractured your inventory is. Every location adds incremental safety stock. Safety stock in fashion, where each color/size combo is a unique sku, tends to be at least an order of magnitude greater than the mean forecasted sales...much higher for the high end stores where an out of stock situation is a major hit to your brand image.

Pure e-commerce fashion companies have a huge advantage in inventory management because they aggregate their inventory in a single warehouse instead of spreading it out amongst hundreds of retail stores. But they have struggled because of concerns about fit. People tend to fall into two categories when it comes to buying clothes online: 1) Buy it anyway, try it on, and return everything that doesn't fit, and 2) Don't buy at all. #1 is extremely costly because reverse logistics is extremely costly (personal experience is 3-10x more expensive than equivalent forward logistics). #2 is a no-revenue situation.

Bonobos is doing something risky, sure...but it is novel and, in my opinion, has a lot of merit. They let people find what fits, and then they can buy as little or as much as they want, in any color, fabric, or print combination that they want online...and they have eliminated the reverse logistics and reduced inventory working capital by several orders of magnitude.

And sure, they can't be everyone's target market. Nobody has ever succeeded at that in fashion. But what they do have for a target market is extremely powerful: Professional men. And they happen to go back for more every time because they love the product.
it's still somewhat perplexing the extent to which vectorized code is necessarily slower

The vectorized code typically allocates all kinds of intermediate results (more GC, more memory accesses). Apparently, turning it into loops is less trivial than it seems.

I'm thinking that the future of GPU enabled languages will mean vectorized code will be faster, so I prefer languages with a bias towards vectorisation.

I share that concern. Julia has some libraries to support GPU programming, but I don't know of any plans to have the core compiler take advantage of it.
I see so many comments defending this obscene, blatant, pilfering of the public coffers. Call a spade a spade people, this thing is a massive scam. San Fran must be lousy with greasy wheels.

Agreed -- would also love to see an incentive structure around publishing negative results. One of the areas of research I think is the most exciting is artificial photosynthesis, and it's currently at the phase where the researchers are trying to discover efficiency gains by just trying out a bunch of different materials.

Take this recent publication [1]:

> For water oxidation, the photoanode surface was protected from corrosion by a 62.5 nm
layer of amorphous, hole-conducting TiO2 that was grown by atomic-layer deposition (ALD).

> The TiO2 layer
significantly improves the stability of III-V photoanodes in a tandem structure for water
oxidation while the tandem structure produces sufficient photovoltage to sustain the efficient,
unassisted production of hydrogen by water splitting in aqueous alkaline electrolytes.

They discovered that coating the photoanode with 62.5nm of TiO2 helps stabilize the reaction. But who knows how many materials they went through to get that one? And how many different coating thicknesses they tried before settling of 62.5nm? This tech could be next-gen solar, would be great to see the global rate of discovery increase. Perhaps YC Research can start this trend?

> what if you need a strongly-typed data exchange format

I'm not convinced that "strongly-typed" is an attribute that can meaningfully be possessed by a data exchange format. "Strongly-typed" is about allowed actions in processing data, not about the inherently-static format of data exchange or serialization.

Sure, but it's not very convenient.

I regularly MITM a connection between a mobile app and a HTTP server, when something isn't going quite right. A look at the JSON they exchange exposes the problem in under a minute more often than not. If I want to test something out quickly, I simply modify the incoming / outgoing JSON by hand. It's rare to get the syntax wrong and involves no context switches. I can then go back to the code, find the relevant section and make the changes I need to make. I find this a very convenient way of debugging and I don't think it would be as nice to do this with a binary format.
