So? She could be the chief engineer, but in the video she is the model, the stand-in, the demonstration person. Call it sexist if you want, but it is standard marketing practice to use young women/girls in promotional vids. Where movement is involved, models with long hair are also preferred as it shows the motion, something that again tends towards young girls. Smaller people also make products seem larger. Where the product involves a seat (cars, air travel etc) a really tiny person makes things look much roomier and more comfortable. Where the action is recorded at a distance people with clear skin but darker lips and larger eyes are more expressive, again trending towards females. Where there is any sort of perceived physical danger you pick models that, rightly or wrongly, are perceived delicate. Use a 250lb Army grunt with massive muscles (of any sex) and viewers might think they also need to be tough to enjoy the product. So this vid is following standard marketing practices in selecting a very standard model.

My point still stands. What would rigging for several non-small people on this thing involve? Looking at the angles on those cables, a 10-fold increase in payload might need a 20 or 30-fold increase in cable strength ... adding weight ... needing stronger cables.

After watching it a couple times more, I'm also interested in how it would handle asymmetric loads. How much before it tips into a cats cradle of wire? Is there any feedback into the system to detect such situations?

Not sure why it's "clearly inspired" by Apple Watch; Does anyone else think all the smart watches look the same?
My favorite source of laptop bags for several years now has been Waterfield Designs: http://sfbags.com

Although I tend towards custom-fit sleeve cases that I can slide into the other things I own (such as my trusty LL Bean backpack), all of their bags have a great quality and seem durable enough to likely last well against the weather. There's also a bunch of nice touches, such as their messenger bags use "airplane buckles" for easy one-handed access.

In C (and in all other languages I can think of), an array is actually a pointer to a bunch of memory. Indexing into the array calculates offset from the array pointer, and grabs the item at that offset.
What's probably going to happen is a marketplace will open up and unused IP blocks will go to those willing to pay for them. Eventually the cost of deploying IPv6 will be less than the cost of IPv4 addresses.
It does serve one purpose well, though. If you knew somehow that holding onto the money has a negative rate of return right now, then you're better of spending that money on something that could make you money later.

For example, at the height of a bubble when P/E ratios are crazily out of whack, taking a class that improves your quality of life or net income potential might be your best investment.

It's a fair criticism. They even felt the need to address it in their announcement.

If Apple released a new Apple Watch tomorrow, early adopters would feel cheated and may think twice about buying future products so quickly.

The Kickstarter approach exacerbates this problem. I understand that many people that bought the last Pebble product don't even have it in their hands yet.

Well, the information isn't copied... so if you modified the incoming array you modify the original, so in that sense it has to be a pointer. Arrays and pointers are analogous in C except when they are declared, as there is an implicit allocation of information. Since we don't want this when it comes to array arguments, it simply decays.
This needs to be far higher.
If you look at the history of South SF Bay, it has always been a string of commuter communities.

It started with the train to take workers into SF and the rich out to their mansions on the weekends. It exploded in the 1950's with affordable automobiles, and houses went up everywhere.

Now the workers are going the other way and the South SF Bay infrastructure is being crushed by it.

Mad Max: Fury Road is not a business plan
Because that's how the machine sees C arrays. It would take an extra (invisible) parameter on the stack to implicitly pass the array size into the function, a thing which is very much against the spirit of C.

The only real surprises/magic in C are things like:

- addition/subtraction on typed pointers has an implicit multiply by sizeof(type)
- type conversion between floats and ints
DNA is just a small part of what makes up the functioning whole of an organism. The Transcriptome, Proteome, and the Metabolome are just as important to determining the outcomes of genes.

It's like understanding what parts are in your car but not knowing how much gas is in the tank, how far the pedal is pressed, or even what gear you're in. It's still an incomplete picture.

Disclosure: I studied cancer metabolism in grad school so I'm a little biased to think that the Metabolome is the functional endpoint of genetics and all its associated modifiers.
Like DocBook?

https://en.wikipedia.org/wiki/DocBook
Because the compiler gets the length of an array from its declaration. However, inside a function the compiler cannot tell the size of the actual array parameter.
I don't agree: Back then I was a very knowledgable baseball fan (I probably could have named almost every player on every team) and I didn't know. I heard occasional rumors but nothing more persuasive than that, and nothing at all which indicated, in any convincing way, how widespread it was. When Jose Conseco talked about it, he was ridiculed as a nutcase and shunned (as expected; see my comment above about loyalty).

I remember when home runs and offense increased dramatically, to record levels, and everyone was saying that the ball was juiced - nobody suspected it was the players who were juiced.
Can't you turn them off though?
Show HN: CrashBreak – A new approach for production exceptions and bugs
Hello! Some time ago I was working on an application that had many bugs and reproducing each one was time consuming. I thought about making this process faster and more user-friendly.

Recreating bugs manually in the browser by typing data and setting all connected modules in the same way like when the exception occurred can be annoying. Also, there is no certainty that the bug is reproduced in the same way it occurred. The other problem is that many of the bugs are hard to reproduce and connected to different layers of the system.

The idea of CrashBreak is to reproduce the exception from the staging server on the programmer’s computer by running a request test. In order to do this the library needs to dump your system piece by piece. Currently we have 3 dumpers: for database, all request data (headers, url, body) and user session.

We tried to create the whole system in an adaptive way. It means that you can write your own extensions to adapt the library to your needs.

The ruby beta of the service is ready and available at crashbreak.com.

Please give it a try and send me your feedback so I can make CrashBreak even better.

Thank you kind strangers!

It isn't that it is ok -- but having rich people and businesses move to Oakland, pay taxes, and thus better fund things like schools, police, and other jobs will help with poverty. Because the violence isn't uniformly distributed and thus isn't targeted at them, it is less of s deterrent.

Also, a lot of that current violence is due to war on drugs and after effects, so the best way to address it is to wind down the war on drugs.
> And Rust's solution to buffer overflows is the same as every other language — run time bounds checking.

Right, because that's the only way to do it? What's wrong with that?

The point is a language like Rust has built-in bounds checking...
Because address allocation is inefficient and it is impractical to address this inefficiency in IPv4.

ARIN is out but your ISP has extras. Why doesn't your ISP sell its extras, since a scarce resource should have monetary value?

Routing tables.

Selling individual IPs off piecemeal isn't practical because routers simply do not have enough RAM to handle the enormous routing tables that would resultantly be necessary in order for packets to find their destinations.
Thanks for your feedback.

I'm not sure yet what is causing the problem. It could be that someone just registered the domain because i cache the results for a few minutes.. or the api I use produces too many bad results.. I will hopefully figure it out.

Your other point is already on my todo list and will be implemented soon. I'm still in the process of unifying different affiliate merchants.. using some of them directly, some via CJ makes things ugly (code wise).
> Two years ago, US consumers could see more than 240 detailed health and trait reports, including risk factors for heart attack and type 2 diabetes. Then, at the end of 2013, the Food and Drug Administration clamped down. They implied that 23andMe's tests were inaccurate. They also worried that some consumers would misconstrue the risks, seeking out unnecessary treatments and changing their medication regimes without speaking to their doctors.

I can't even begin to describe how much this enrages me: I, a purportedly-free citizen of a purportedly-free republic, am not permitted to pay a firm to do its best to give me accurate information, because some unelected third party is concerned that I may make bad decisions based on that information.

What business of the State's is it if someone chooses to change his medical regimen without consulting his physician? It's his regiment, not the State's; it's his health, not the State's.

I'm a free man: I should be permitted to consult the best firms and practitioners I can in order to make decisions for my own lifestyle.
Small publisher here. I believe Ebook sales have been generally flat or declining for many titles for the following reasons:

* Pricing issues

* Huge influx of new/republished titles entering ebook distribution channels are outpacing demand, including many free or low-cost self-published titles

* Kindle Fire sales negatively impacting ebook reading habits encourages people to do other things besides read (video, apps, games, etc.)

* Decline of marketplaces/platforms that are unable to compete, e.g. Nook, Sony.

* Subscription plans (especially Kindle Unlimited) eating away at paid digital downloads.

* Some people prefer print

Many established publishers are still focused on print because that’s where the sales are and that’s where they still wield considerable power. For the short technology guides I publish, print accounts for 70-80% of sales. Certain ebook marketplaces that could be doing well (Apple iBookstore, Google Play) have really stagnated, unfortunately.
Hehe thanks! Glad you like it. It's really really good to hear positive feedback after all that time tinkering with it :)
That didn't work out so well for all those people who tried to short VW back in 2008...
A lot of this is down to history. Way back when lots of these blocks were allocated, not only was IPV4 exhaustion a non-issue, but allocations were either in /16 or /8. So if 65 000 adresses (a /16) was too few, the next step up was 16 million.

I don't think there's that much to worry about. If a VC wants a liquidation preference, that's fine--they'll have to pay for it by giving me a better valuation (in other words, giving me money money more cheaply).

The market corrects for all of these kinds of things.
While it's sad that there are so many large and unused blocks (Apple, DoD, etc), whats worse is the disgraceful adoption of IPv6 by ISP's.
FYI the equivalent Go code would actually copy the whole array on the stack, and so it would be valid if possibly inefficient depending on the size of the array.
It's an obvious desperate attempt to get attention by making a hyperbolic statement. It's sad to see that it is working.

> Authors have taken to breaking out a book's chapters and releasing them individually [1] to capitalize on this model.

This is exactly how many classic novels and other long works of literature were originally published in the Victorian and Edwardian periods [1]. For genres like SF and Fantasy, this remained a common model well into the twentieth century. I don't think there's anything inherently wrong with a modern return to serialization of longer works; it's actually kind of neat -- greater optionality for the reader.

I chalk up expensive art the same way I do with money laundering amongst the elite.
with those same cables, they would probably be able to carry hundreds of people at the same time... just make the platform a bit bigger and maybe upgrade the winches.
List is just one part that makes the C++ impl sub-optimal. All the scenes are allocated on the heap so you're actually bouncing around memory twice(once for the next link list entry, second for the actual heap allocation).

Lastly the virtual call again has the chance to cache miss(although probably only once seeing as we've just got a few impls).

In a small example like this there's a good chance that most of the heap allocations are close together but put this approach into production and you can very easily see fragmentation start driving up your cache misses.

(FWIW I'd also store radius*radius on creation, use a BSP/kd-tree and all sorts of other tricks that really help in these types of computations).
So does C++: http://www.cplusplus.com/reference/stdexcept/out_of_range/
Even in Copenhagen, 10km (6 miles) tends to be about the furthest most people bike. A few do bike further, but it really drops off past that. For the longer commutes, people do a hybrid bike/rail trip. If you're 5km from work, often it's easiest and fastest to just bike directly. If you're 20km, it's more common to bike to the S-train. Depending on your job location, you either take the bike with you on the S-train and continue biking from the other side, or you park it at the station and just take the train in.

I only ride hybrids, I've ridden my hybrid on steep mountain highways and gravel roads, although mostly thousands of miles in the city. I agree that wider tires are best. However, having a durable bike with durable tires doesn't "solve" the problem of riding on gravel, it just makes it less painful. If Silicon Valley actually built a decent bike network I might consider moving there from Seattle.

As it is I'd feel like I'm paying a premium to put up with worse infrastructure.
until people learn how and, more importantly, willing to build good urban space, as a resident of MV (or of SV in general as i lived in other near by cities before) i am even against current 3 story "barracks" being actively built all over the place.

For example, one can build 30 story (plus 10 underground for parking/storage/etc...) towers with enough green space around it instead of covering all available space with the 3 story-s.
Why we’re no longer using Core.typed
>Have you tried getting additional IP addresses?

Yeah. The price doesn't suggest scarcity. I guess the thing with the routing tables makes sense. I wonder if there's a way to rationalize that without it getting too messy. IIRC ipv6 thought of this and split up its address space in a roughly geographical way.
People are not usually interested in reading literature from original exemplar. It was a digital art from beginning.
I often feel a bit guilty when I spent time looking through something instead of just giving it a quick glance; but knowing that Linus has to fight the same fight really gives me confidence that it's better to know whats going on than to just ship code out the door.
"It seems people in the US fetishize road bikes with drop bars and skinny tires as the 'best and fastest' kind of bike" I don't think that true. The general opinion I've seen where I live is that bikes are toys and paying above a few hundred for one is ridiculous.

I do agree that you probably don't want a race oriented road bike if your goal is to commute to work a few miles but if you enjoy the sport and know what you are getting into then go for it get as awesome a bike as you can afford. It's better than wasting it on some huge car. Bike value should be > car value ;p
Lower population density areas are easier to make bike friendly, less people which means that taking off road lanes or making sidewalks slightly narrower has a smaller impact.
It also means that other bike infrastructure like parking is easier to build (need less of it).
Construction is also easier when you either do need to move buildings at all, or you are moving 2-3 story buildings instead of huge complexes.

Fixing public transportation is more important than fixing biking at this moment, especially in California. When more people move with cars than with public transportation it's harder to allocate the needed resources for bikes, the impact of public transportation improvement is also quicker and bigger than improving bike lanes.
Not saying that having a bike / walk to work alternatives isn't important, but jumping straight to it when everything else isn't even remotely close to being right is a foolish mission in my book.
>The point is a language like Rust has built-in bounds checking...

As does C++. See e.g. vector.at and libstdc++ debug mode:

https://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.h...

The difference is only opt-in vs. opt-out. To its credit, Rust provides additional protections against iterator invalidation and dangling pointers, but its approach to buffer overflows is the same.
There's no excuse for it not being waterproof to at least the 1m level. What's their problem? It doesn't need to be openable. The previous models were not. Just seal it up permanently, preferably under dry nitrogen so it can't corrode inside.

It's more about how the cable is managed in terms of slack, keeping the cage from flipping over, etc. I agree with you, the cable itself is an unlikely point of failure.
I've been really happy with C++ lambda's lately.

Would be nice to see Rust's Option<T> and Result<T,E> ported over to C++ since I find that error handling extremely elegant compared to most C++ approaches.

True, and it would be an argument if you couldn't preview the first few chapters of a kindle book already.

The problem lay with Amazon, not the authors. The authors are rational actors reacting to the changes that Amazon made to their marketplace. By trying to push their subscription model, Amazon is inadvertently reducing the quality of their ebook marketplace.

> What the frack does Halliburton need with 16 million IP addresses?

Who cares? If they gave them back to IANA tomorrow, IANA would be out again in 2 weeks, at the rate of demand they were seeing the last time they had any blocks to assign. It would probably last even less time, now.

Do the class A allocations suck in retrospect? Sure.

Is it worth flushing time, effort, and money on trying to recover them? Hell no.

Whatever amount of money it would cost Haliburton to restructure all of their internal networks and rewrite their applications to compactify their IPv4 usage would be far more efficiently spent if they simply used it to upgrade their infrastructure to IPv6.

Putting any money into IPv4 is just throwing good money after bad at this point.
