> That is simply not true, the helmet will be the first part of you head that touch the ground in almost any fall.

Citation needed.

From both personal experience and research I've seen about this, the head is rarely the first part to hit the ground.
My brother did have a rare accident as a kid where his head hit the ground first and he had a concussion, but that's an exception.

And it's generally not hitting the ground that is the dangerous part in traffic accidents. Helmets don't do anything useful is the vast majority of accidents.

Odd. I found the exact same opposite. Granted, I have been using Jekyll for some time now and only tried Hugo for one afternoon. But I found Hugo very opinionated in how the site should be structured and it felt more like working with a CMS than with a static site.
> The fact that you can ride a bike without a helmet in The Netherlands is a sort of democratic miracle of the 70's where the public convinced the politicians to make bikes a first class mode of transport. The effect of this is that almost every road in The Netherlands has some sort of provision for bicycles, or has at least been considered to have some. And in most cases not just in the form of a line but actual infrastructures, curbs, asphalt

China must be a real paragon of democracy.

> the only usage of "unikernel infrastructure" is essentially to hack around elevating privileges for networking in macOS

(author of the talk here)

That's correct, although I view that in a less dismissive light than your comment above suggests :-)

The "unikernel infrastructure" movement hinges on turning as many systems layers as we can into libraries, so that they can be repurposed in the future in different contexts. This can also include using them in _exactly_ the same way as you use systems today (e.g. compiling unikernels to Linux binaries pointing at a socket stack).

But when a problem comes along that requires challenging conventional layering, having unikernel libraries is a game changer. Without this, we would have to maintain a much more heavyweight emulation system, which in turn drives up complexity and resource usage. In the D4Mac/Win case, putting in the VPNKit library layer gives us a lot of flexibility in mapping to existing socket stacks, and also lets us open a broader conversation about what network bridging should look like in the next generation OS stack. Whatever that answer is, we know that solution isn't what we are forced to live with today -- root level privilege and importable kernel modules required to shift Ethernet packets around. Perhaps the answer is something more like FreeBSD's declarative Netgraph framework, or an OSX-style launchd socket registration system that works across higher level protocols including TLS, or something else entirely different. But until then, the unikernel infrastructure lets us solve the immediate systems problem at hand without letting that design decision vomit all over the rest of the application stack and burden us with a ton of technical debt.

> It sounds like MirageOS was only used because it was a reasonably portable network stack

It also happened to be the one that many of the team had authored, and written in a high-level enough style that we knew how to invert it. Nothing dramatic here, just picking the shortest solution to get shipping software that solved real user problems (in this case, VPN and firewall support on OSX/Win).

I expect that pulling off the same trick using several other user-level network stacks is also not hugely difficult, but I haven't used lwIP for some years to find out. The Rump Kernel NetBSD stack is probably the best alternative to start with, or the HalVM TCP/IP stack. The IncludeOS C++ one is also rapidly becoming a mature candidate.

Was that first email reply a thinly veiled fart joke? Seems like they don't really take cold pitches seriously (or people for whom English is not their first language).
It depends on the type of fund.

For VC funds almost all deal origination is referral or outbound, virtually none is cold inbound.

For seed accelerators the majority is cold inbound.

500Startups sits in a slightly odd category between those two so it's behaviour is likely to be unusual in any case.

But she makes a good point about the quality of referrer as well, who gives you the referral to a fund makes a huge difference to how much attention you'll get. As a fund if you treat all referrers as equivalent then you're inevitably going to get a lot of junk (anyone who works in VC has a huge network).

Some funds go so far as having formal categorisation of referrers (platinum, gold, etc.) based upon the quality of their dealflow and rewarding them based upon that.

It makes sense for some things, when measuring it would be more trouble than it's worth. The first website I ever made was hosted by a two man garage company that offered unlimited* bandwidth.

I Germany this is taught as 'Schulterblick' ('over the shoulder look') in driving school (which is mandatory in this country).

In general, you are taught to always use Schulterblick when:

1. Changing lanes.

2. Entering/exiting from/to a ramp.

3. Turning.

4. Getting out of a parking spot.

5. Opening a door to exit the car.

Modern rear mirrors are curved at the outer vertical edge to avoid any dead spot.
This means just checking the mirror before you do any of the above should -- in theory --, be enough (except for some cases of 3).

But better safe than sorry.

An exception are trucks. They have a dead spot at the right which the driver can't check. Mercedes introduced a an electronic solution for this in 2014.

While that does happen, you get people forking the original project and so on. And it should be noted that if a piece of software works "well enough" then there isn't really a need to update every two weeks -- the software works and don't touch it. If there's a bug that's bothering them, then you can absolutely pay a contractor to modify the code and fix the bug (that's what contractors do). Obviously the contractor wouldn't be happy to implement huge new features, but that's why you should fund the original project so it doesn't die.

(author of the talk here)

This talk was more of a roundup of interesting uses of library hypervisors. The two are:

- the HyperKit/MirageOS use in Docker for Mac and how it can augment a native client application

- the far more general new Solo5 backend that IBM/Docker/Cambridge have contributed to MirageOS3, which shows how to use a library hypervisor to build a very Unix-like unikernel experience. MirageOS developers have also taken advantage of the libraries to add support for FreeBSD/bhyve very easily [1], so these new backends and libraries are increasing MirageOS library portability quite a bit.

>Instead of always calling gettimeofday() / time() / now() function to get the current time, in a piece of lower level code, try to pass it in as an argument.

Any code that uses time based scheduling should use a virtual implementation of time/scheduler to allow testing - this way you can say "sleep 10 hours" and then "move virtual time by 10 hours" and actually verify that the timeout is hit without the tests actually taking 10 hours. It also lets you test out logical edge cases such as `<=`, `>=` vs `<`, `>` which is surprisingly tricky with timeouts.

If you look at the ifixit tear down, the Samsung GN 7 battery also looks smaller than the iPhone 7 Plus battery. I can't imagine having a higher energy density is doing Samsung any favors.

To be fair, a lot of these problems are induced by having such car-focused cities in the first place. That extreme focus on making cities car-compatible makes them less livable for every other user of the infrastructure (cyclists, pedestrians, public transport users).

In my opinion the right way to go would be to drastically improve public transport (so it actually IS a competitive option) and in an overlapping process reduce car infrastructure and replace it with pedestrian/cycling/public transport infrastructure.
Wait, do people in the US not use professional driving instructors in modified instruction cars? Doesn't that cause a lot of accidents?

Right. There's no doubt that wearing a helmet makes you safer. Helmet use should be encouraged. However, the outcomes for society are considerably worse if helmets are made mandatory.

This has been demonstrated by the experience of New Zealand where helmet use was made compulsory in the 1990s. Not only did cycling rates decline by more than 50%, the rates of serious cycling injuries and deaths actually increased. It turns out that when there are less cyclists on the road, remaining cyclists are more vulnerable - helmet or not.
Well I wasn't taught the 'Dutch Reach' either when I got my driving lessons. I also have never heard the term before and it certainly is not standard practice.
OK, throw this into the mix: many of you reading this have smartphones which are voice controlled, and for which voice control is activated at all times. In the case of Google, that processing must take place on Google's centralised servers. Siri may or may not do centralised processing (and can operate in standalone modes). Microsoft's Cortana, Facebook's "M" (IIRC) and Amazon's Aero are all various stylings of "Stasi in a Glade form factor", as Maciej Czeglowski so memorably put it.[1]

Voice stores distressingly cheaply in terms of space, and with the Internet of (broken) Things (that spy on you), odds of finding yourself surrounded by microphones in the most unexpected locations,[2] controlled by a wide variety of quite probably competing interests.[3] And if they cannot find what they're looking for in the surveillance tape itself, they'll simply manufacture their own evidence using your own phonemes[4] and video.[5]

I've even registered in this project because I thought it would be literally "Pinterest for code".

Well.. an EC2 instance running Linux is not a process or even a container, even if functionally it's easier to treat it like one.

It is a full virtual server with its own Linux kernel and operating system: it has to be updated, secured, and maintained just like any other Linux server. Most Linux distributions on an EC2 instance have dozens of processes already running out of the box.

I understand your point -- that ideally a single instance can be treated as a single functional point from the point of view of the application, and I agree, but not from a point of view of security. As you know, in any larger environment, there are likely many additional support applications running on that server: things like app server monitoring, file integrity, logging, management, security checks, remote data access or local databases, etc. Those must not all be treated with the same levels of security and access. (i.e., why would rsyslog or systemd need access to all objects in our S3 bucket or be able to delete instances or any of the other rights that might legitimately be granted to an instance via an IAM instance role?)

To treat security for all of these processes as if they're all part of the same app tosses out decades of operating system development and security principles and places your single function app, as well as that of your entire environment, at grave risk. I.e., there's a reason why a typical Linux distribution has about 50 accounts right out of the box and everything doesn't just run as root.

If you are developing or deploying microservices or containers and don't want to be burdened by the security requirements, then there are alternatives at AWS like ECS and Lambda that you should seriously consider.

A Hard Lesson in Police Body Camera Policies
To match an anecdote with an anecdote - I've been using S4 for 3 years, and then gave it to my brother (I've upgraded to S7 with contract renewal), who's been using it for the past year too. The phone is still going strong. Feels slow-ish today, true, but still better than some of the cheaper Android phones OOTB.

I blame Android's continued bloat creep[0] for that slowdown though. My brother had S3 before, and so does my SO, and they were all becoming less and less usable with time and each system update...

There is also a study that shows other traffic participants engage in riskier overtaking when a cyclist wears a helmet. Instead of leaving 1.5 m space when the cyclist is on the side of the car, drivers leave an average of 0.5 m space for cyclists wearing a helmet.

If I remember correctly, drivers see helmets as increased safety for the cyclist and feel they can engage in less safe behavior because it evens out.

NFV Speeding PoC to Launch
Damn, I guess it's been too long since I've done (or thought about) circuit theory. But yeah, the general idea of HVDC is a frequency-free current:

http://www.cleanlineenergy.com/technology/hvdc/how

And now I'm trying to think my way through it:

There is definitely DC with no frequency component, e.g., battery circuits. You've got a cathode, an anode, and a flow between them.

I'm trying to sort out if DC can have a frequency component. I seem to recall that rectified circuits can operate by basically (pardon crude metaphors) chopping off the negative side of the phase. You'll have a wave pattern, but it's all going in one direction. Pushed through sufficient capacitance or impedance and you'll likely smooth that out as well.

Which is getting me to wonder just how a DC generator works.
Is it paranoid of me to associate the disappearance of removable batteries with our apparent steady steps towards an Orwellian future? Or no?
The point is that the non-assertive position isn't 'playing it safe'. You're no more out of the flow of traffic unless the lane is extra wide, you're signalling to following cars that they are welcome to overtake, and you have robbed yourself of any margin for error when a car misjudges their pass and squeezes you in to a parked car or railing.

You're right that the assertive approach is no substitute for segregated infrastructure, but in an imperfect world of mixed-use roads, it's the best way to stay safe, and is the method taught and recommended by many bodies here in the UK.

If you could build 2 $100,000 apartments or 1 $1,000,000 apartments, which would you do? You know there's a massive shortage of housing and whatever you build will definitely sell. The cost of making the luxury apartment is not actually that much higher than making the other 2.

You'd be a complete idiot to build the affordable housing.

Planning laws and NIMBY are limiting the amount of buildings builders can make all around the world, so naturally the only buildings they bother making are the luxury ones with the big, fat, juicy returns, unless they are forced.
That's total nonsense. If someone throws a door in your way you're going to get hurt, no matter what, which was what started this whole discussion in the first place. See, 'safe braking' makes some assumptions about what other people will do and when they don't all bets are off. That's why we call them accidents to begin with. Cars turning without signaling, doors, swerving into the space occupied by a cyclist and so on. There is absolutely no way to protect against any or all of that.

If everybody would be traveling at their 'individual threshold for safe braking' there wouldn't be any cyclists at all.

> People who cycle on roads expecting cars to take full responsibility for their safety are unlikely to last very long.
> A cyclist needs to operate within their own safety tolerances, rather than expect others to provide safety to them.

And that attitude is the heart of the problem right there. Cyclists can expect other traffic, especially armored guided projectiles to take their fragility into account.

I sincerely hope you're not a driver. And if you are that you stay away from my country, it took a few decades to get rid of that attitude here and the number of accidents dropped in spite of more people in traffic, including kids and the elderly.

Cyclists absent other traffic have a very good safety record, as soon as you mix traffic at different speeds the situation gets dangerous especially if the stronger of the two parties expects cyclists to provide their own safety, by nature of being unprotected humans they need cooperation from other traffic.
