icanhackit··on Tesla Q2 2019 Letter
> My comment is saying it doesn't matter if they wanted to use it for something as trivial as ECU updates

What I'm saying is that you've completely missed the OP's point: The advantage Tesla has in the autopilot space is that they are able to have hundreds of thousands of real-world test units for their autopilot systems by running the neural net in parallel with the driver inputs (i.e. shadow mode) versus companies that at best have a few hundred test units thus limited material to improve/iterate on their deep learning models.

A metaphor for the situation is Apple playing catchup in the AI and voice recognition space to Google because Google had years of material and huge sums of it to build their deep learning models while Apple had comparatively little. The underlying technologies used by either company might be very similar, but you can't throw hardware at the problem to play catch up -- you need that real-world input/learning material for the deep-learning model to be robust.

>> Being able to test your code out in the real world and dark launch a feature gives Tesla a ridiculous advantage.

> Is the comment I'm responding to.

And that dark launching includes sending the latest neural net builds to the fleet to safely shadow test the changes, collecting millions of hours of real-world telemetry and rapidly iterating without end users even needing to pick their nose. You either intentionally or through ignorance reduced OP's statement to being an OTA ECU update that you "could literally put that together with scraps in my garage".

But feel free to keep shifting the goal posts.

icanhackit··on Scientists discover chemistry that may help explain the origins of cellular life
As an aside, when reading this I considered a fun alternative theory (I'm not actually proposing it as any kind of truth) that if it's ultimately discovered that the processes behind the creation of life are just too complex to be duplicated in our universe...

...Rather than invoking a god which comes with its own problems (i.e. who/what created the creator) one could infer that life came from a universe where the physics/conditions for creating life are possible, and life somehow crossed branes moving from one universe to the next.

Consider a reverse/inverted universe where instead of space being a void, space is solid containing voids/cavities/pathways between voids, allowing complex chemical processes to occur naturally and at great scale.

icanhackit··on Tesla Q2 2019 Letter
Running the latest neural net build in a shadow mode pitted against the real world driver and relaying back telemetry where the shadow NN took an opposing action is a little more sophisticated than pushing out an ECU update.

I think you're being a little uncharitable or simply don't understand what Tesla are doing.

icanhackit··on In Japan, a growing number of car-sharing users don’t rent cars for driving
Sounds like an opportunity to me. Have a rule that you charge by Km travelled or fuel used, whichever is greatest $-wise. Also have a car where the interior can be quickly converted into a bed...a double bed.

Bonus points for electrochromic glass for privacy. The glass can only be activated when the car is fully stopped with the handbrake engaged.

Uses: sleep, sex, rest, air-conditioned space, heated space, eating space, electrical outlet for phone or laptop, quiet room, change room...oh and a car. Basically anything a hotel can be but also portable.

Add automated driving to the equation and who knows what kind of a beast the industry will be in a decade.

Intrinsity wasn't cheap given it was primarily for IC design tools (Fast14). Though you might argue it was a good deal for Apple because it possibly gave them an edge that other IC design houses lack.

icanhackit··on How Apps on Android Share Data with Facebook (2018)
> The only way to crack down on this is to prevent apps sending any data at all and to minimise the use of proprietary software.

You're asking for legislative controls which, at the end of the day, can still be bypassed either flat out illegally or via legal grey areas. At best it's remedied after the act or prevents only the most obvious misuse. When you give politicians the mandate to control something often they're too technologically/process incompetent to get it right and to make sure the solution is in your interest.

You want to abate this practice? Exit social media (...and life will improve), use RSS for mass information consumption (I've been doing it for ~10 years now - I can pour through what would normally be a days sifting/reading in 15 minutes while taking the first dump of the day) and use a browser with extensions that give you more fine grained control i.e. Firefox with NoScript.

Be in control of your world.

icanhackit··on AirPods with Wireless Charging Case
/r/nudism on Reddit is ok, not ground-breaking but it's a nexus to other resources as well being a place for general discussion.
icanhackit··on AirPods with Wireless Charging Case
People collect cars, watches, shoes, expensive clothing. On the extreme end there's figurines, paintings, antiques -- at least the former items have utility, the latter are mere articles for signalling to others.

Does it really blow your mind that the ability to move freely without being tethered to a phone is a selling point? I can give an example where it really helps for me: I'm a nudist.

But even when clothed I like walking around able to take a call or listen to music without snagging a cable on one of the many protrusions in this world like door handles, kitchen cupboard handles etc which can also lead to an expensive phone launching from my pocket onto the floor.

If you're worried about pollution, Airpods should be on the low end of the concerns list.

icanhackit··on The yeast that can be used to brew cannabis, not beer
> there will be no putting that genie back in the bottle

Great observation. You could unwittingly transport it because it's microscopic. You could post tiny quantities in/on everyday objects to any country. Replicating it to usable quantities takes days not months, and a few containers in terms of space not whole crops or basements full of lamps.

This will be game-over for nonproliferation.

icanhackit··on The yeast that can be used to brew cannabis, not beer
As an interesting aside hops and cannabis are related - they're both part of the Cannabaceae family.

As someone who enjoys craft IPAs/NEIPAs rich in hop oils, have hemp protein powder in my breakfast shakes with hemp milk and love the odd puff of the peace pipe, I've got to say it's a remarkable plant family.

You can eat it, drink it, wear it, use it as a medicine, get drunk (well, it's a flavouring and biocide - not the source of alcohol) and get high from it.

icanhackit··on Intel ends 5G modem alliance with Beijing-backed chipmaker
> As other have said, iPhones have an external modem and are fine. Qualcomm insisted on this because they had it, and they're good at marketing.

Addressing the second sentence - I have no knowledge of what transpired but my assumption would be a combination of Apple didn't want to have their SOC's fab'd by Qualcomm for the sake of an integrated modem, and Qualcomm didn't want TSMC fab'ing their modem IP into Apple's SOC's, so the obvious solution was a discrete modem which was a product they could offer.

icanhackit··on Apple's move to ARM-based Macs creates uncertainty
> Devices that used to work and used to get updates simply stopped at one point.

Which devices? I kept using my G5 iMac until 2008 without any issues and with regular OS updates.

> Pages

From what I recall, and perhaps what I'm thinking of happened further down the track, Pages had issues in spite of changes to hardware, not because of it. Apple pared back the functionality of its office software when it transitioned from paid to free software, breaking some of the formatting features.

icanhackit··on Apple Falls from First to 17th Spot in 'World's Most Innovative Company' Ranking
> Air Pods are one of the best innovations in mobile in the past 5 years.

Agree. I have a set of Bose Hearphones - a pseudo hearing-aid which cancels ambient noise while enhancing human voices. It's been quite life-changing when having dinner at a restaurant with friends where previously I'd sit in silence because I couldn't make out what people were saying. It's also great for talking while walking down a loud street where previously I'd just walk in silence because I couldn't hear that well...

...but I mostly leave them at home and always carry Airpods for when I want to make a call or listen to music. Other wireless headphones are too big, clunky, and charging them isn't as simple as dropping each bud into a tiny magnetically secured case. So simple and one of my favourite tech products in a long time.

icanhackit··on Apple's move to ARM-based Macs creates uncertainty
Given how smooth Apple's transition from PPC to Intel was, and how much experience Apple has with ARM in their portable lines -- if/when the complete transition to ARM happens it'll probably be a brief blip on everyone's radar and likely increase competition both price and performance-wise in the desktop sector.

What's stopping Apple from adding hardware-level emulation to their SOC's, even if it's only partial functions, to ensure cross-compatibility doesn't take a serious toll on performance? x86 would be patent-encumbered but I'm sure there are a few creative ways to reduce that burden.

icanhackit··on Did Australia Poke a Hole in Your Phone’s Security?
I'm not arguing with your point that Australia is a nanny state, but for clarification...

> We have lockout laws preventing us from entering drinking establishments after 1am

Currently for a large section of the Sydney CBD and inner suburbs encompassing Kings Cross new entrants to venues are blocked after 1:30am and last drinks are 3am. This does not apply to areas of the City of Sydney like Surry Hills or Newtown, which can remain open all night. I believe the trading hours for licensed premises have been recently relaxed by City of Sydney to areas including Glebe, however I'm not 100% on that.

Still, it's pretty sad as Sydney's nightlife, particularly in Kings Cross, was a big draw-card for younger visitors and residents alike.

icanhackit··on Here is my collection of 600+ “old” digital cameras
It'd be interesting if development on sonar autofocus systems continued - they could work in the dark where phase detection and contrast detection have difficulty.

A compound eye of phase detection points, laser, sonar as well as regular contrast detection would be interesting. Each has their own strengths and limitations.

(For context the camera listed above uses sonar autofocus - basically echolocation)

> How are you SURE that smartphones will still be a thing in 20 years?

I'm sure someone asked a similar question about personal computers in the early 80's. They didn't go away when smartphones became prevalent, they became computational work-horses and in the same way an AR system will never be able to pack the computing punch and battery life of a smartphone.

But similar to how a smart-phone complements a PC, AR tech will simplify how we interact with specific parts of the world around us like navigation, notifications, and merge with existing tech like wireless earphones with noise cancellation and conversation/audio-enhancement to provide minimum necessary utility.

More features will bleed down the chain from PC to phone to AR, but with size comes certain advantages and disadvantages, and a large object can always hold more juice and computational power.

I think the biggest disruption will come from global low latency wireless internet - suddenly computational power can be uncoupled from the device and AR would be able to offload the power-hungry CPU/GPU's and large batteries needed for fluid and powerful interaction. But I'm not sure Elon Musk's satellite internet project will be that disruptor - so it might be another long wait until that next big thing happens.

icanhackit··on Korg NuTube, vacuum tube for the 21st century
Interesting bit of trivia: The Noritake Group, the parent company behind Noritake Itron who make the VFD module, specialise in ceramic products ranging from circuit boards, dental materials, electronic paste to fine china. That's what I love about Japanese companies - the utter complexity of their product lines and exhaustive use of in-house talent. Though as Sony can attest, it can be their undoing as well.
icanhackit··on Elon Musk Unveils Boring Co's First Tunnel
> You seem to be assuming a single tunnel per direction. Assume 20 instead.

I think this is the really important part. Think of it like a computer bus - do you want a single channel able to move a lot of data at once but with potential bottlenecks as various systems fight to talk to each other, or lots of channels able to move medium amounts of data without bottlenecking one component while favouring another?

When one channel is at capacity you move to the next, with further redundancy to spare.

icanhackit··on E-cigarettes around 95% less harmful than tobacco, estimates landmark review
It's worth noting that tobacco contains harmala alkaloids [1] which are monoamine oxidase inhibitors (MAOIs). So it's possible those who persist with smoking in place of vaping or other nicotine delivery mechanisms might be doing so because they're (unknowingly) self-medicating for depression.

icanhackit··on Musk’s Boring Company is launching DIY watchtowers with bricks from tunnel dirt
I might not have been clear - I mean using the dirt and rocks in the concrete mix, not replacing precast panels with dirt bricks.
icanhackit··on Musk’s Boring Company is launching DIY watchtowers with bricks from tunnel dirt
Just a thought...

Normally the concrete reinforcement panels that line tunnels are precast based on calculations for how many they'll need to complete the project, which makes sense because tunnels are usually large one-off infrastructure projects.

Boring Co, which wants to be in the business of making tunnels constantly and for anything from transport to utilities, could look into making a Just In Time process for precast panels using tunnel dirt/rocks to mix with concrete and for aggregate.

It'll use only a fraction of what they dig up, but reducing waste and improving process is always a good thing.

icanhackit··on Gaia spots a 'ghost' galaxy next door
Ant 2 is known as a dwarf galaxy. As structures emerged in the early Universe, dwarfs were the first galaxies to form

[...]

What makes Ant 2 even more unusual is how little light it gives out. Compared to the LMC, another satellite of the Milky Way, Ant 2 is 10,000 times fainter. In other words, it is either far too large for its luminosity or far too dim for its size.

The scifi nerd in me wants to believe it's a result of an ancient civilisation shrouding huge numbers of stars in Dyson Spheres, waiting until they collided with the next galaxy that they could feed on.

icanhackit··on Apple walks Ars through the iPad Pro’s A12X system on a chip
> his role in Apple is to provide strategic direction and guidance

That's the feeling I got, as well as perhaps being a human abstraction layer between the engineers and the executives. If you can describe in relatively understandable terms something that is technically difficult to thousands of laypeople (well, that's unfair - Anandtech was for nerds but being a nerd doesn't make you an IC/EE engineer), you'd be an asset to both the corporate and engineering teams.

And that translation works both ways - understanding the direction of the company with regards to future products vs what you want to get out of your silicon teams (e.g. when Anand mentions thermal envelopes, that might include an understanding of the limitations stemming from the potential form/design and material of a future product).

> On the other, I remember the Power days. Having non Mac users “talk down” to me about using a different processor was beyond annoying.

Sample size of one and all that - but for me it was a selling point. The PowerPC G5 (PPC 970) was intriguing when it first came out. Having been with Intel, Cyrix and AMD systems since the 286 and used them since XT (Intel 8088) days, it was nice to muck around with something new and paired with OSX Tiger it was such a fun world to explore. The move to Intel felt like a bit of a letdown, but by that time I loved OSX and Snow Leopard cemented it as my OS of choice.

Apple desktops/laptops moving to custom silicon would excite the nerd in me. I want competition.
