_s··on Driving Amazon’s electric delivery vehicle: Rivian EDV [video]
^^ This 10000x.

Sure there are some nice comforts and features that will make life easier for the operator, but on the whole it's a massive step backwards in actual durability, utility and usability.

_s··on Software horror show: SAP Concur
I would even go as far as saying the opposite - engineers too "competent" for their own good.

I've walked in to so many code based where very talented individuals have made incredibly complex systems, using all their technical know how of best practices & patterns, abstraction layers and facades ... and ignored the fact that all they needed was a three field form with a submit button.

It's not just worth knowing if you can, it's if you should.

_s··on GitHub is releasing two open-source fonts: Mona and Hubot Sans
Just a quick note - the "body" text on the page uses Alliance, also designed by the same studio I think (https://degarism.com/Alliance). The two fonts themselves are catered more towards headers / titles.
_s··on WhatsApp goes down for users globally
Not P2P.
_s··on Ask HN: Am I getting older or did typing on the iPhone become unbearable?
Yup - I've turned off slide and predictive and it seems to be exactly how it used to be - infinitely easier to get the words in to the point where you don't even need to look at the keyboard!
_s··on 5G’s Rollout Rattled Hundreds of Pilots
Going through the process to type certify the Max as anything other than a 737 would’ve been far more expensive, slow and painful for Boeing and all its customers because of how slow and difficult the FAA is.

They added the MCAS because they didn’t want the Max to be a different type, which meant starting the certification process from scratch. They were able to self certify precisely because it was a 737 type.

Yes - there were many issues that lead to the accidents and you can’t really point to just the one thing; but ultimately it did boil down to a culture at the company created by the environment it operates under.

I’m not defending Boeing here - if anything, I’m more upset at them as they had the engineering will and talent, the political and financial backing to make meaningful changes to the regulatory environment and make aviation safer as a manufacturer - but they chose greed.

Lastly, that’s nowhere near what I said but I can see how you can get to that conclusion. I’m an aviation enthusiast and a Pilot (feel free to go through my post history) - and it’s not a question of weakening regulation; it’s a matter of streamlining ways to get new technology certified faster - it only took 3 decades for the FAA to give the STC for unleaded gasoline etc etc.

_s··on 5G’s Rollout Rattled Hundreds of Pilots
I think there is some context missing from this;

The 5G band that was auctioned off is only one step next to the band used by radar altimeters - essentially a piece of equipment on aircraft that gives it its precise height above the ground.

Aircraft can and do have barometric (pressure corrected) and GPS altimeters as well (which are usually giving you your height above sea level - and knowing the height of the terrain you can work out your height above ground), all of which feed into the various systems allowing them to have an accurate height at any given point during the flight.

This is most needed when flying “precision 3D approaches”, usually in bad weather when visual contact with the ground may not be possible until the wheels actually touch the ground. Autopilot systems that land the aircraft fly these “approaches”, and thus rely greatly on their height, speed and distance.

These radar altimeters were mostly designed and certified back in the 80’s (or even earlier!) - and it’s a lot of work to have any equipment certified - especially today. Hardware + software back then was nowhere near as good as it is today, yet many of these altimeters still being produced today would be to the original spec from a few decades ago - which had a much wider tolerance or sensitivity to the frequencies, so when you have a frequency only a few steps away - a slightly older / worn equipment with perhaps not the best shielding will definitely pick up some surges from frequencies next to it.

Blame the FAA for their archaic and slow, near impossible process to get equipment certified. Blame the Aircraft / Equipment manufacturers for not updating their equipment with the times, but that’s on the FAA for making this process difficult- see 737 certification as an example, leading to the max accidents.

_s··on Users without a cell connection find they can’t get back into their Zipcar
I've been a member of ZipCar for well over a decade, from when they first came to London and issued the plastic NFC cards. Then it was the smaller ones that could attach to a keyring, and for the past 5 or so years - just the mobile app.

This is very anecdotal, but I never really had any issues - even more so, the last ZipCar hire I did took me from downtown SF to the Muir Woods (no cell reception at all). I had no issues locking / unlocking the car during the trip - I'm fairly certain it uses bluetooth for the connection between app and car; but likely needs data for starting or ending a trip.

_s··on Ask HN: Who is hiring? (October 2022)
The Lead React Native Engineer role seems to have expired.
_s··on Toyota CEO talks about why he isn’t all-in on EVs
Adding to this - the i3 was a game changer in terms of materials and manufacturing. The i8 is still an excellent hybrid sports car - available long before the electrically boosted exotic cars were released.

Lastly - I was happily driving an electric 1er convertible in Berlin under the DriveNow car share back in 2012!

They’ve been in the EV game far longer than people realise; and have the iX1, i3, iX3, i4, i7, i8, iX either available now or within the next 12 months.

This is not to gloss over their current subscription based hardware access, which is in poor taste, but obviously people are still buying their cars.

_s··on At 4.4 miles, Wyoming team sets new rifle shot world record
Think about a CD or an LP spinning; the outside is going a lot faster (it’s covering a lot more distance in the same amount of time) than the inside yet the RPM for both is the same. The earth is the same :)
_s··on Cirrus Vision Jet Pilot Pulls Chute in Florida
Nearly always in the event of an engine failure or an unrecoverable attitude; which may be a spin.

Cirrus’s transition training emphasises pulling the chute - the seats and airframe are designed to absorb the vertical impact and protect the people on board. Most other aircraft you learn to pick a field to glide into, or do spin / unusual attitude training to recover from them. The chute is essentially a get out of jail free card for when you don’t have the options for any of those things.

_s··on Cirrus Vision Jet Pilot Pulls Chute in Florida
Some more context - this the first deployment of the BRS system in their flagship; the Vision Jet.

The Vision Jet is also the only turbine (jet) engine powered aircraft with such a system.

It also boasts the Garmin Safe Return system; where the autopilot lands the aircraft in case of Pilot incapacitation - doing everything from radio calls, selecting the appropriate airport and runway, flying the approach and landing to a stop.

_s··on FAA approves unleaded fuel for piston fleet
Cheap, abundant, easy to acquire, easy to transport, inert, mostly harmless if left alone, maintains its properties in harsh conditions over extended periods of times, mixes well with some other chemicals.

Very harmful if ingested or absorbed, directly or indirectly.

_s··on Spate of polio outbreaks worldwide puts scientists on alert
From my understanding - there are two main “strains” for polio; one that is “wild”; endemic to Afghanistan and Pakistan, and one derived from the oral vaccine, endemic in Africa and a lot of conflict zones, from Asia to Europe to Central / Southern Americas.

The oral vaccine in use in a lot of the world contains a weakened version of the virus, and allows your body to fight it off without any negative effects. This is usually a 3 or 4 course vaccine.

This specifically engineered weakened virus has been shown to mutate and infect other partially or non vaccinated individuals, including causing paralysis, and is the one now popping up in more developed / inoculated areas - but again, in unvaccinated individuals.

Note - from what I have read, you can still get and spread polio even if you are vaccinated (much like Covid), but it’s an incredibly low chance - and furthermore, your risk of serious disease / paralysis / death is even lower (so we know the vaccines work). The oral vaccine (weakened virus) efficacy is much higher than the injected (inactive virus) vaccine too, and boosters are offered for those who had the vaccines as children and are now adults.

There is also another oral vaccine, with a weakened virus, that has been engineered to prevent certain mutations that cause it to spread (if I read some articles correctly), but is not currently approved for use in the US / UK.

Polio was one of the first few horrible diseases almost eradicated by vaccines. Whatever your stance on getting vaccinated, do understand that Polio has a 1 in 200 chance of resulting in severe symptoms and paralysis, and there is no treatment for it - only prevention via inoculation. It is not like Covid where mostly the older, more immunocompromised suffer - it will ravage children and healthy adults too.

_s··on What I don’t like about working at a remote job
Working from home, or remotely is not for everyone - neither is being in an office.

Some folks thrive in an office environment, they value the things it provides - a schedule, a time, a reason to get up and out, socialising with others, being out in the world. It comes at a cost of time and a bit of freedom; you don't really get to choose the hours or where this happens, neither the folks you interact with.

Others prefer working remotely, they cherish being able to set their own schedule and work, and being able to manage their level of interactions with others. Remote work does not have to be work from home either, and the freedom this gives can be quite liberating.

There is also a somewhat of divide between introverts and extroverts between which they prefer, but of course - there are many in either camp leaning the other way too.

You just have to find what works for you - and that means trying both, or a mix, and seeing which one suits you best.

Where it gets rather frustrating for folks is when they are not given a choice - some companies; ergo leaders, can't wait to have everyone back in an office even after 2 or so years of being (mostly? somewhat?) productive during the pandemic; and this is where frictions arise. Other companies are entirely remote, and for those who thrive in an office environment, they will struggle greatly.

I'd love to see managers / leaders, and even employees recognise that individuals have preferences, and being accommodating of it to get the best out of their people, rather than imposing how they find they work best. How, or what this would entail, I'd have to give more thought - but I believe there are plenty of individuals with far more experience and knowledge than me around this topic who have been successful at managing hybrid (office + remote) teams, and accomodating individuals that lean either way.

_s··on Inbound container volumes to the US are reverting to pre-pandemic levels
It isn't - we should be (and a lot of larger corps are) encouraging higher standards for workers in those places, and it is significantly better compared to a decade ago. Not to mention as those workers demand better wages and conditions, it suddenly starts to make economic sense to hire locally.

We should not be taking steps backwards and making that sort of behaviour acceptable, because if we do that at home - then places with already lower standards will compete by lowering theirs further.

_s··on Man sues American Airlines over identification, jail time
Depends on the size of the firm, and how much you interact with them.

A local law office with 1-2 lawyers and a few assistants; likely $1000-1500 that’s held by them to put towards any future requirements.

Larger firms range from $5000-25000 for an individual, but again, usually this money is held in a trust on your behalf and you can use it to pay down any bills or let them keep it and pay the invoices as they come.

_s··on Inbound container volumes to the US are reverting to pre-pandemic levels
Hmmm I didn’t get that impression from this;

> corporations would be in US jurisdiction but the employees could flow through with minimal overhead

It implies to me that the corporations get to be US based and reap those benefits while employees are not and can be taken advantage of.

Though I do agree with you - there’s a few experiments happening with special economic areas / designated cities in a few places (again, a few in the Middle East) to attract talented individuals and companies to whom local laws may not apply.

_s··on Inbound container volumes to the US are reverting to pre-pandemic levels
So exploit workers by bringing them from overseas, and treat them differently to the local laws?

You’ve just described Qatar, Bahrain, UAE etc.

Maybe reconsider why local labour is expensive and why it’s worth paying for.

_s··on Ask HN: What should I use instead of Heroku?
I absolutely adore https://www.glitch.com for low traffic, small and simple apps. It’s Joel Spolsky’s project; and he’s got Trello, StackOverflow and FogBugz as his previous companies (Fog Creek I think?). Give it a whirl!

I think you can run PHP on there now too; see https://glitch.com/edit/#!/php-poc

For even simpler (static JS/HTML), I just publish on GitLab or GitHub pages.

_s··on Mygov is a ‘huge disappointment,’ key architect despairs
She’ll be alright = It will be fine, don’t stress.

Doing the bare minimum, with not a lot of TLC.

It makes for excellent work environments if you derive your joy and fulfilment from activities outside of work, but can be immensely frustrating if you want to deliver on quality (or expect quality delivered).

_s··on US Navy wirelessly beams 1.6 kW of power a kilometer using microwaves
Yes, any vehicle that can be drive with a motor.

Here’s an out there scenario - a few power generating aircraft or satellites in high orbit sending power down to drones at lower altitudes, and vehicles on the ground that just have inverters and motors. No costly batteries, let alone the logistical supplies required for fuel and maintenance for combustion. You are no longer limited by the slow moving fuel vehicles; a blitz is a whole other thing now.

Generators and solar arrays are the backbone of most forward operating bases - no longer. You have so much more freedom and space as you are no longer restricted by your power / fuel requirements.

It will shift the balance of war, vehicles, infrastructure, logistics.

For less military uses - imagine doing away with power cables entirely. No more costly infrastructure built above or below the ground. Just a few towers (much like mobile phone towers) transmitting to households. Depending on where the technology goes, imagine not needing batteries in anything anymore. You’re just hooked up to the wireless grid for power too.

It’s still in its infancy, but this is pretty significant.

_s··on A Tesla vehicle using ‘Smart Summon’ appears to crash into a $3.5mm private jet
Composite fuselage - and the jet engine ($$$) itself sits between the ruddervators ($$$), with the BRS ($$$) just in front - probably the worst place to hit that jet. Easily $1-1.5M.

A wing or the nose would have been far easier to inspect and replace.

_s··on Ask HN: People who use different emails everywhere, who sold you to spammers?
I’ve had a few folks use my email. This is going to prove wildly unpopular but I just reset the password using the email, go in and delete the account (or submit a ticket with support to do so).

They can make a new one with their own email if it’s important.

_s··on A YouTuber purposely crashed his plane in California, FAA says
Yup I see the distinction and I agree with you. It also means that you will loose that right for breaking any rules / regulations of that license; but the gray area I guess is the unwritten rules governing safety alongside written ones.

We’ll likely see amendments codifying those unwritten rules into existing legislation soon enough.

_s··on A YouTuber purposely crashed his plane in California, FAA says
It is a privilege though; just based on:

- Having the money to afford the training for the pilots license

- Having the time to complete the training and stay current

- Having no health issues that may deny you a medical

It is pretty out of reach for most people with out the time / funds for it.

_s··on A YouTuber purposely crashed his plane in California, FAA says
Just to add - getting permission alone is a few man-years worth of paperwork for planning, executing and cleanup.
_s··on Impressions from a first-time Mac user
If your workflow is dependant on many files, and with that naming convention because of it - there’s a good chance the workflow could be cleaned / simplified greatly. Wether it’s worth the effort or not, I don’t know - but lots of tools / freedoms / restrictions make certain processes possible and it’s always worth revisiting.
_s··on Long-term cardiovascular outcomes of Covid-19
Adverse sounds serious, but really:

About 105 vaccine recipients reported at least one AEFI symptoms following COVID-19 vaccination (incidence proportion 6.4%, 95% CI: 5.3%, 7.7%). All AEFI reported were minor which were managed by tablet paracetamol and subsided after 1–2 days. Fever (65, 3.98%) was the most commonly reported AEFI followed by myalgia (54, 3.30%) (Fig. 1). About 48 (2.94%) study participants reported 2 or more AEFI, most common being fever with myalgia (19, 1.16%) and fever with headache (18, 1.10%). No severe or serious AEFI was reported among vaccine recipients.
