The article concludes by asking what we'd do with a wearable computer, but that's not the right question to ask. We already have wearable computers, but we call them "smartphones".

Instead, we can think about what uses we have for new interfaces on these computers. Gesture-based interfaces have existed in browsers for a long time. And my friends from the subcontinent would say that they've had precursors for many centuries[1].

HUDs do represent something "new" (in terms of availability, not technology). So perhaps, every time I look at an ad, I get a red/yellow/green indicator of their rating by the BBB. Or I look at a printed URL, make a gesture, and it's bookmarked for me. Think of the data overlays that you could actually use and could likely be monetized quickly.

What I fear, of course, is selling ads into my eyes based on what I'm looking at, because everybody (particularly Google) seems to think that advertising is the primary way to fund the web and mobile apps. I already hate billboards around town: this seems like an opportunity for a sea change in how we monetize our work.

The blogger might be an ignorant, but the OP post doesn't reassure me. If I go in a 5 months travel doing consulting abroad, and I'm living alone; who guarantee that my car is being constantly put on the charger? There are many cases (plug dysfunction, electric problem...) and $40K is not a trivial amount.
Most battery management systems incorporate some sort of cell balancing algorithm to make sure cells stay close to a common voltage. Usually this is some sort of resistor (per cell) that dissipates a small current from that cell and bleeds it off as heat. This is usually used while charging to get everything in line.

That said, if a cell goes bad or has an extremely low capacity compared to the rest, there's not much you can do...
That is true, however that particular reference frame already seems somewhat privileged thanks to Mach's principle.

Of course I state this as a theoretical point only - there is absolutely no reason to suspect that any such thing is possible.
Eh, "retiring" to me generally means "making sure I have enough money that I don't have to die on the street". Saving for retirement is more of a precautionary act than a journey to a destination.

Mouse auto clicker
I just want to share my favourite program, when it comes by mouse auto clicker. The name of the program is AutoClick and it works perfectly.
Actually, it seems to me the article doesn't really contradict the accusation at all.

There is a fundamental problem when any rechargeable battery is discharged and then left to sit for months. Any boat owner understands that that's why you plug in a trickle charger when the craft is put into storage.

The line above indicates, on the contrary, that yes, if you don't drive it for a while and it wasn't plugged in to a sufficient power source, your car will in fact be bricked, and potentially damage its batteries. Apparently this is a problem with boats too, but that doesn't change the fact that it's a problem with electric cars.

This "response" is in fact full of double speak... Check this one out:

Another error on the part of the blogger is the claim that if the cars discharge fully, the battery packs will be damaged. This is blatantly false. The battery management system of the Tesla Roadster keeps the battery from being discharged to a damagingly low state of charge under normal driving conditions.

"This is blatantly false"......."under normal driving conditions". The original article was not talking about normal driving conditions. This reads like a deliberate attempt to mislead.

If anything, it seems to me that this article validates the claims made in the other article. It states:

This is the most likely explanation for the five "bricks" that the blogger claims to have heard about. They probably aren't actually bricks, but cars in need of servicing.

This is hardly the kind of certainty-filled rebuttal that one would expect if the original article's claims were, in fact, incorrect.

Because the primary reason your phone is as big as it is, is because of the screen.

A big, bright screen forced a big battery.

I don't know what the battery usage on a HUD screen is, but I suspect a lot less - they don't require backlighting for a start.

That cuts down on the battery requirements, which cuts down on the size & weight (Obviously this is speculation: it wouldn't be a huge surprise if you had to carry a battery pack wired to the glasses somehow)

Secondly, the glasses themselves need to do a lot of fast, low-latency image processing. It isn't at all clear that bluetoothis an appropriate low-latency, high bandwidth connection mechanism for this.

Having said that, I suspect you'll be able to connect to your phone via bluetooth if you want - but the primary processing will be done on the glasses.
The headline should read "Tesla: Not so easily bricked under normal circumstances".

The problem here is that not everyone lives in California, and most people think of cars as durable (vs. perishable) goods. Those two things cause problems for people who are edge cases. In places like Michigan or New York or Massachusetts, it's not 70F all year round. We have this quaint concept called "winter". In the winter, the local governments dump salt on the roads, snow and slush make driving dangerous, and when it doesn't snow, you get dusty blowing salt on the highways.

Because of this, people with the means to buy $50,000 sports cars leave them in garages for the winter. Or they head to the Caribbean for a vacation. Or both. For a car with an internal combustion engine, you usually remove the battery or trickle charge it, but the consequence of not doing so is buying a $100 battery at your local mechanic.

Another thing to consider is the meaning of "normal" as it applies to the market. If you're a working stiff, you drive every day. You may even drive to get to your vacation. People buying $50,000 cars with the limitations that electric cars have today aren't working stiffs, and their leisure patterns are probably quite different than most folks.

Agree -- the whole argument starts off with a false premise.

I'm not surprised. The author, John Cochrane, a 'freshwater economist' (look it up), always sounds to my ears like a broken record: I can usually guess, a priori, what position he will take, and often even what his arguments will be, in response to any economic issue -- occasionally by torturing the facts, as in this case.

To his credit, sometimes he can change his mind -- here's an example: http://krugman.blogs.nytimes.com/2012/02/06/anti-keynesian-r...

To give a taste of how quickly this exploded. This is 1991. By 1995 I was working at a small ISP. The ISP existed only because there was demand to get on the web. I started my masters in 1996 but was then lured away by a job at Cox Interactice Media, a several hundred person division that Cox Enterprises setup just so it could have a web presence. That's just 5 years after this annoucement, and well, we know where it went from there. All for something that didnt exist when I graduated highschool.

Try to imagine inventing somthing with that kind of impact that quickly.

That's not correct. A slippery slope argument, given realistic risk and possibility, can be a valid argument. And that is exactly what all of the privacy concerns are about: risk.

I think we both know that breaches of sensitive and private data are a real danger and aren't some abstract, theoretical possibility that never happens. They happen all the time. Aggregation of personal data is dangerous by virtue of existence, without even touching the moral issue of whether it's ethical to try to spy into people's lives and habits for whatever reason.

Knowledge is power. And knowing almost everything about a person is one of the most dangerous weapons I can think of. Even more dangerous is that most people do not even realize how dangerous that is. They are either unaware of it, or worse, willfully ignorant.

I think the original article also made the same claim: Tesla is "not so easily bricked" (given the fact that 'only' 5 cases could be found). So this isn't a rebuttal.

If it was to be a rebuttal, the claim would be "Tesla cannot be bricked" or something like that.

This article did not do any background work. Why didn't he talk to the Tesla service manager(s) who were quoted in the original article? Even if he managed to talk to 1 of the 5 and showed that it was not a bricking, then he would have a point. But the way it is, the current article does almost nothing to refute the original.

You need the blast that small because the Davy Crockett was to be fired by a human on the ground, not dropped from an airplane.

A small blast can be strategically preferable if you want to fire a bunch in a line in order to stop troops from advancing over a border for several days due to radiation hazards.

It seems that using the weapon posed massive risk for the operator, so it might have been in the maker's interest to make the bomb even smaller.

> This post directly contradicts that notion.

How does it _directly_ contradict that? Ok so he mentions how the management system will stop the charge from dropping too low. How does it do that, does have a robotic arm and goes and finds the nearest outlet, does it expand solar panels, because batteries will discharge even if completely disconnected. And it also highly depends on the ambient temperature. So I don't see a direct contradiction I see this post building a straw man and then proceeded to demolish it.

Look at this another way. So let's say this post is correct and those Tesla roadsters were not bricks. Why in the world would Tesla then charge owner $40k then? Is it saying that a routine recharge and tow costs $40k? Or did Tesla, like a shady mechanic decided to scam the guy and make $40k off of him?

I agree, I actually just threw out a bunch of code and started with a fresh base with a much cleaner OOP structure and could not be happier with my results so far. Things that I was struggling with before are now super simple because everything is properly segmented. The whole process only took two days as many of my classes could be reused and I just needed to fix how they were interacting. Then again I was just correcting my quick and dirty code, I don't know if I would have done the same with a production application as it would be safer to just work on both at the same time until it was in good shape to cleanly replace the first.

I think you're missing the point of the question. I'm not asking how you scale in general, I'm asking whether your replication scheme is only for failover or if it contributes to your scaling story - i.e., if a given key goes hot, does everything have to run through the point leader, or can each replica take writes/serve requests? It sounds like the former, which is fine, just wanted to clarify.
I've run down the battery on my car, motorcycle, mower, or other vehicles I don't often use. It is not an expensive ($40,000) fix -- often it just takes a recharge because lead-acid batteries are not as easily damaged as lithium-ion. Replacement is relatively cheap too.

When you talk about tire deformation, this is rare and would not happen before many years of disuse. And engine seizure? Again, unlikely to happen even if left to sit for a decade. You're more likely to have issues with rust in the gas tank and bad, coagulated gas, than a seized engine.

The point is that it is relatively safe to leave a vehicle unattended in a garage for long periods of time. The vast majority of its value will remain undamaged. Contrast to the Tesla, where if left for a year with a low charge it is alleged that it's likely to lose fully half of the car's value ($40,000).

This is a big deal.

> This sounds like a disaster waiting to happen

Well, define "disaster". A memory-mapped dataset will cause pathological performance only when there is thrashing: If you are accessing a small percentage of the entire dataset, then unused data will be paged out and remain paged out. If the bulk of data being accessed exceeds the amount of available physical RAM, then you will get I/O trashing.

Memory-mapping is a good alternative to static allocation or a home-grown paging system because it lets the kernel handle the dynamics of allocation, letting your application transparently and gracefully handle RAM tension situation by relinquishing memory space to other apps. Kernels (including Linux and Windows) and CPUs are extremely efficient at paging I/O, much more efficient than a hand-written paging system because there's no need for the application's code to check whether a page is in physical memory — that's handled by the CPU itself.

Of course, any I/O incurred by a too-large dataset will drastically reduce performance compared to in-memory speed. But paging in itself does not necessarily lead to "disaster".

"unless Google happens to be working at the height of early 90's tech"

We are working at the height of 90s tech. For a consumer product, cheap enough to mass produce at a price people are willing to pay ($200-$600) you have to step backwards in time a bit for embedded system design.

I've built a wearable using this type of display (the half inch micro display) and the biggest issue is that you cannot resolve an image well that close to your eye without giving you a instant eyestrain headache. You need a lens system to create virtual distance between your eye and the display. This is also the big issue with the "project the display on/in the lens approach." You need to have a focal length for the display similar to the depth at which the user spends most of their time looking, otherwise switching from real world to display and back is rather headache inducing.

I'm really excited about this too, but more for main-stream attention on a field that has been marginalized for over 10 years now.
