This Video Makes Nice Factors About E-Bike Security



Join every day information updates from CleanTechnica on e mail. Or comply with us on Google Information!


I’d like to stay in a spot with wonderful e-bike infrastructure. If my smaller metropolis had devoted lanes with limitations between me and the automobiles, I’d journey locations nearly each time. Separate bike roads can be even higher. However alas, it doesn’t. As an alternative, most locations have a slender “bike lane” with nothing however a stripe of paint to maintain my household protected from drivers with their heads up their apps. On some roads, there are solely “sharrows” to remind drivers that bikes are allowed — a message that goes nearly solely unnoticed by drivers who aren’t accustomed to bikes. HOOOOOONNNNKKKKKKK!!!!!!

However, after watching this video, I puzzled whether or not I ought to give it one other go at the very least on some journeys.

I do should needless to say this video was shot in Tel Aviv, which is clearly going to be totally different than the suburbs close to El Paso. However, on the identical time, it jogged my memory a whole lot of using bikes in Taiwan (one thing I did for some time in faculty). Even crowded streets with out bike lanes may be helpful if you already know what you’re doing.

The primary tip he gave is one I already use generally: avoiding roads which are robust for bikes. In his case, he talks about utilizing bike lanes and little devoted bike paths, however even in locations the place there are not any such devoted infrastructure, there are normally facet roads and again roads which are so much safer for bikes. This would possibly make some journeys a bit of convoluted, however it might probably make the journeys so much safer.

One other necessary tip is to stay seen. Clothes is a part of this, after all, however not all of it. In the event you hand around in blind spots or put your self in locations the place persons are extra tempted to make an unsafe move, you possibly can put your self ready the place somebody runs you over. Positive, they most likely ought to have been paying extra consideration, however that doesn’t repair your accidents or convey you again to life within the worst case. Getting folks’s consideration with hand indicators and eye contact can even go a good distance towards security.

Following site visitors legal guidelines and being conscious of your environment can be key. Whenever you comply with the principles of the highway, you’re predictable to drivers. Zipping by means of cease indicators and site visitors lights, weaving out and in of various lanes unpredictably, and such could cause a driver to misjudge and hit you. Being conscious of the place automobiles are and what’s occurring forward of you can be necessary. Carrying earbuds can be a usually dangerous thought, as your listening to may be an necessary a part of consciousness.

One other necessary aspect of consciousness is searching for cues. Drivers usually present what they’re going to do earlier than they do it. Attempting to squeeze over, issues drivers would possibly wish to keep away from, and lots of different issues may be predicted should you concentrate.

Velocity is one other large issue. In some circumstances (heavy site visitors, lane splitting, pedestrian areas, automobiles which may door you), slowing down is nice. However, maintaining with the circulate of site visitors generally means going quick. This makes Class 3 e-bikes a good suggestion, but it surely may be a good suggestion for governments to begin permitting “class 4” e-bikes that sustain with 35-40 MPH site visitors higher.

Security gear can be necessary. Helmets are usually not all the time required, and many individuals don’t wish to put on them. However, should you carry a brush or comb alongside, it’s potential to repair your hair up while you get to your vacation spot. Different issues like motorbike gear are good, however many individuals can’t realistically try this.

community – Why is symmetric NAT known as “symmetric”?


tl;dr It comes from STUN and is symmetric as a result of it identifies a 1:1 relationship between NAT mapping and L4 move.

The title symmetric NAT is so far as I do know launched by the unique STUN RFC 3489, with the next definition:

A symmetric NAT is one the place all requests from the identical inside IP
deal with and port, to a particular vacation spot IP deal with and port, are
mapped to the identical exterior IP deal with and port. If the identical host
sends a packet with the identical supply deal with and port, however to a
completely different vacation spot, a unique mapping is used. Moreover, solely
the exterior host that receives a packet can ship a UDP packet again to
the interior host.

This may occasionally not make clear issues in case you are not that conversant in NAT and the entire idea of STUN. Let me attempt to construct this up.

The primary necessary idea is the 5-tuple (protocol, host port, server port, host deal with, server deal with) the place protocol is mostly both UDP or TCP. This 5-tuple is used to determine a L4 protocol move. I take advantage of host and server terminology to simplify some issues and keep away from directional phrases akin to supply and vacation spot.

Now, the entire idea of a NA(P)T system is to dynamically change the (host port, host deal with) on the interior community (inside) with a (NAT port, NAT deal with) on the exterior community (exterior). The state of such a translation can be known as a NAT mapping. At its simplest the NAT perform doesn’t care about protocol, server ip, and server port. On this case a number of Layer 4 protocol flows could use the identical NAT mapping, so long as the host ip and host-port used on the within are the identical. This N:1 mannequin of multiplexing/demultiplexing flows to mappings is commonly represented by way of a funnel or cone.

The most important various is to create a mapping for every new 5-tuple. So even when for instance all of protocol, host ip, host port, and server ip are the identical however server port is completely different, a brand new mapping can be created and the ensuing NAT ip, NAT port can be completely different. There’s thus a full 1:1 symmetry between a layer 4 move and a NAT mapping.

Not related to the query, however just a few historical past why this time period is definitely necessary for the STUN RFC and never left as an implementation element. One of many objectives of stun was to allow P2P connections between two purchasers behind NAT. The concept was that for a lot of purposes (e.g. VoIP) there would solely be preliminary communication by way of servers, however all remaining communication could be P2P. To arrange this P2P, the purchasers would make a connections to a stun server, which does three issues:

  1. It informs them on the kind of NAT, as this solely labored with the ‘full cone’ model. So detecting cone vs symmetric is necessary right here (stun has a couple of variants of cone really)
  2. It creates a NAT mapping as defined above.
  3. The stun sever informs the consumer of the surface port+IP of that mapping.

Then, the consumer would ship the realized port+IP by way of the applying (voip) server to the opposite consumer, and now that can be utilized to arrange a P2P connection.

In apply this barely works, and stun as described there was obsoleted and changed by RFC 5389. As well as, many NAT implementations have added Utility-level Gateways to resolve sure protocols immediately. On high of that there are particular protocols to create NAT mappings on demand, most prominently UPnP IGD and PCP. However, as typically occurs, a few of the unique STUN ideas caught endlessly anyway :).

Regulatory hurdles additional complicate the panorama, as putting the precise stability between fostering innovation and making certain privateness plus security requires considerate coverage growth. By addressing these challenges proactively, AI can turn into a strong software for bettering world well being fairness.

How essential are collaborations between governments, tech corporations, and well being suppliers in making certain accountable AI growth and deployment?

Collaboration amongst governments, know-how companies, and healthcare suppliers is not only helpful—it’s important for the accountable growth and deployment of AI in well being. These partnerships allow the creation of complete frameworks that handle moral issues, safeguard knowledge privateness, and set up operational requirements that guarantee AI is each efficient and reliable.

By working collectively, stakeholders can transfer past fragmented, one-size-fits-all options and as a substitute develop AI-driven approaches which can be tailor-made to real-world well being wants. This implies leveraging AI to reinforce diagnostics, streamline scientific workflows, and develop entry to high quality care—significantly in underserved areas. Furthermore, collaboration fosters transparency and accountability, making certain that AI stays a software for empowerment fairly than exclusion.

When innovation is pushed by shared accountability and aligned with public well being priorities, AI has the potential to reshape our strategy to well being in a means that’s each transformative and equitable.

What moral issues needs to be on the forefront of AI-driven well being options?

Once we take into consideration the moral issues in AI-driven well being options, there are a number of key areas we have to concentrate on. First, now we have to handle bias mitigation to make sure AI fashions don’t unintentionally reinforce current well being disparities. Transparency can also be essential, because the decision-making course of behind AI have to be clear and comprehensible to all events concerned. Accountability comes subsequent, with clear traces of accountability for any choices made by AI techniques, so that somebody could be held accountable if issues go improper.

Autonomy is on the very core of moral AI in well being, which implies it’s important that we not solely respect however actively assist folks’s rights to make well-informed choices about their care. This goes past merely offering data—it’s about making certain that individuals totally perceive their choices, the potential dangers and advantages, and the position AI performs the place it’s employed.

We should assure that the customers or those that profit from AI really feel empowered and assured of their decisions made, figuring out they’ve a say within the applied sciences that have an effect on their well being and well-being.

AI fashions in well being have typically demonstrated biases. How can regulators and AI builders mitigate this danger?

To mitigate biases in AI fashions, it’s obligatory that regulators and builders concentrate on constructing techniques which can be consultant of various populations. This begins with gathering knowledge from a variety of demographic teams, so the AI is educated on data that displays the real-world variety of sufferers. However knowledge alone isn’t sufficient—steady monitoring can also be key, as AI techniques needs to be frequently assessed to determine and proper any biased patterns which will emerge over time.

Involving a wide range of stakeholders within the growth course of, together with ethicists, affected person representatives, clinicians, medical specialists, and so forth., can usher in helpful views that assist make sure the AI fashions serve everybody equitably and pretty.

How can governments and organizations be certain that AI-driven well being options responsibly use affected person knowledge?

To make sure that AI-driven well being options responsibly use affected person knowledge, governments and organizations have to implement robust knowledge governance insurance policies that clearly define how affected person data is collected, saved, and shared.

Anonymization methods additionally play a core position in defending folks’s identities, making certain that knowledge can be utilized with out compromising privateness. On high of that, adhering to each worldwide and native knowledge safety legal guidelines is important not just for sustaining belief but additionally for making certain that AI techniques are working inside authorized boundaries. This strategy helps create a basis of safety and transparency that advantages each folks and the well being sector as a complete.

What are the largest obstacles in regulating AI for well being, and the way can international locations overcome them?

The fast tempo at which know-how advances involves thoughts first. Rules typically wrestle to maintain up with how shortly AI improvements are rising, leaving gaps in oversight. Moreover, policymakers want a deeper understanding of each AI applied sciences and the distinctive complexities of well being to craft efficient, knowledgeable laws.

One other hurdle is the dearth of world standardization—with out constant laws throughout international locations, it turns into troublesome to foster worldwide collaboration and be certain that AI options could be safely and ethically deployed worldwide.

To beat these obstacles, international locations might want to spend money on steady schooling for policymakers, work in the direction of harmonizing laws internationally, and keep agile in adapting to new technological developments.

International locations can handle these obstacles by fostering steady dialogue between technologists, well being professionals, and regulators, and by investing in schooling and coaching packages that bridge information gaps. HealthAI, for instance, is tackling this by its World Regulatory Community (GRN), which strengthens native capability and capabilities in AI regulation for well being, making certain that regulators worldwide are well-equipped to handle the evolving panorama of AI in well being.

How does HealthAI assist international locations construct and certify accountable AI validation mechanisms?

As an implementation companion, HealthAI works along with governments, ministries of well being, and different well being organisations to navigate not solely the security and efficacy of AI-driven well being instruments but additionally their moral compliance, making certain that the know-how aligns with each regulatory necessities and societal values.
