You hit on what I suspect is a missed opportunity on their part. There are a lot of businesses which seem to be thriving on the “too cheap to bother canceling even though I stopped using it” idea, like the $10 gym memberships you see.

Perhaps they could have come up with a drastically price reduced membership which only allowed for a couple of days of use per month? It would have eaten into some of their full memberships, but I suspect they could have dramatically grown their membership in that fashion.

2017 was the biggest year for blockchain by a huge margin by many metrics (see https://coinmarketcap.com/charts/). there is now 200 billion dollars in this space, give it another year or two. Some things will shake out for sure, probably a lot of it, but many efforts will lead to production applications.
Bitcoin cannot be expected to be priced "correctly" (whatever that means) since there's no practical way to short it.

The statements aren't true at the same time. Racism—of the personal kind—is very common (nigh universal), even if much of it is subconscious.

There are vast piles of research showing that personal racial bias manifesting through discrimination, whether or not it is conscious/intentional, is pervasive in America.

Structural racism is real, but it is not independent of personal racism—it is produced by and perpetuates personal racism.

Ok as a mechanic a few million questions:

* What happens when a wheel seal goes? Do I have to remove all that ridiculous plastic on #2,3 axels??

* What happens when a tire blows? Is it going to destroy all that plastic and take out a few more tires in the process?

* Why all the glass? I've spend entire days replacing windshields for a 12 or so truck shop which generally come in two (drivers and passengers), the Tesla semi would require a crane and expensive replacements.

* Why is there no bumper or frame attachment points? Bumpers save the truck from damage, no one wants to buy $xxxxx front end, lights, etc when a deer in the bushes jumps into the middle of the road.

Honestly from my point of view it seems Tesla tried to apply personal EV to a semi. Did they do any research from tractor shops or mechanics? There is a HUGE reason tractor/trailers are easy to service.
I think it is good to remain skeptical about medical ML, but I don't think it should be because of the algorithms or that retrospective analysis is flawed. In most retrospective medical research, the data sizes are relatively small. Likewise current ML needs huge amounts of labeled data to be accurate, and patient data just isn't available to ML experts in the volumes necessary. The question I have is would dramatically increasing the size of available patient data improve ML analysis? Is it the case that some of the flaws of retrospective analysis are actually a result of too little data especially in the context of ML? I don't know the answer, but I do know we need to fix the data availability problem if we want to find out. How do we fix the data availability problem? Not sure either, it a complex problem.

We did this in our entire house for about 6 months once when our water heater broke and we couldn't afford to get it fixed quickly.

UPSIDES: We nearly halved our water bill as all of us (kids and parents) took far shorter showers because it was so cold. This also meant we had to clean the shower much less often. I would also be more awake and alert in the morning after a cold rinse.

DOWNSIDES: I noticed I was getting more headaches and stiff necks, then I realised that the hot showers were helping me to de-tension and relax my shoulder and neck muscles which have become tight due to my long work hours writing code at a keyboard.

Didn't notice any up or down occurrences of sickness in the rest of the family. Overall, I am glad we have hot water back now. At least I have a choice which way to go.

I really don't see this as a major problem. Just have the ability with your compiler to load a external syntax tree for the specific database sql dialect. Then have the ability in the syntax tree to define types that map directly to a type within the language.

Easiest approach would just be to resolve the syntax tree to a constant string that is then sent to the database. I don't know why for the vast majority of programming languages they lack a lot of language features that programmer do day in day out eg... text manipulation, xml parsing, json parsing all of which are pretty straight forward and time consuming in languages without multi-line string literals.

The general-purpose computer. It's a dinosaur on the verge of extinction at the hands of walled-garden app stores on phones and tablets. I never, ever expected that to happen.
Hmm, have you heard of SingularityNET? There are plenty of projects being made that have real, valuable uses for blockchain tech. Marketplaces are one of them. If you want an app store that isn't controlled by one corporation that can force you play by their arbitrary rules, blockchain can allow this to happen. A centralized front-end is necessary, but that's all it is, a front-end. They have pretty much zero incentive to play hardball with the customers.

You're right that most of it is over-inflated hype. But to say the technology is useless is a stretch.

This is petty and shallow, but I'm annoyed with programmer culture in the sense that people always phrase this sort of question in terms of "what if the person that gave us so much kicked off" rather than "what if they were unavailable or retire"? It's morbid and sort of implies that the only way that person would ever stop is if they died.

It leaves me feeling slimy. It's intended to say this person is so dedicated they would never ever abandon a software project of their own free will. In the case of free (as in beer) software projects, the author is often not even compensated. It really makes it seem like the people that are helping you are entirely subservient to the machines and the wanton desires of others. It also appeals to the serious business person that lives in the hearts of so many developers where only the harshest framing can be considered as dealing with the world in real terms.

Anyway, carry on. I just wanted to say my piece.

Right they meet even violent offenders with "physical restraint" so long as they are not met with violence. And "physical restraint" is little more than asking a person to turn around and cuffing them, and in some cases - that's not even involved.

We could discuss the ethics of imprisonment, and I expect we'd agree. But you certainly can't claim that police's task is to deal out violence - particularly preemptive.
In Switzerland, people also stand in two lines next to the doors, so people can get out first. Everyone follows that, the ones who don't are mostly young people who aren't used to riding trains. They get starred down pretty quickly (social inhabitor in Switzerland #1) and learn to adapt.

Bitcoin is no more speculation than gold. Gold has its price. It is rarely used (I have not seen anyone exchanging value using gold). It cannot be eaten, drunk, lived in, or used as a tool (I guess you can use it as a weapon like a brick). Yes, it is used to make jewelries because it is expensive not because its intrinsic usability or functionalities (there are other metals or plastics that look better and weigh lighter than gold). Yet it is expensive. As a matter of fact, it is harder to use gold to exchange value than Bitcoin because you have to weigh gold and test its purity.

Most semi-trucks are filled with proprietary technologies. Then more such is layered on by fleets, leasing companies, maintenance providers, etc.

Little of it natively works together. The contractual limitations are nuts.

From what I recall technology often isn't shared between automobile and truck manufacturing companies owned by the same parent because of these restrictions.
That's 10,000 Nm (aka 7375 ft-lbs) wheel torque. The hellcat has 650 ft-lbs engine torque. First gear in the hellcat is 4.71:1 and rear axle ratio of 2.62:1, which gives you 8021 ft-lb at the wheel at torque peak. In second gear, we have 5347.

So, a small car with more wheel torque than a Hellcat in 2nd gear, nice!

Edit: Used incorrect ratios, updated.

Hmmm. Doesn't Tesla usually offer a loaner car while a Tesla is in for repairs? If they did the same thing with semis, would shipping companies accept it?

The semi is quite interesting. The presentation was a bit underwhelming, Elon was very nervous and the stuttering wasn't something I expected. To me this shows how great Steve Jobs was salesman, when he did his presentations.
I remember analysts and experts in 2004 sneering at the thought that Google might be worth $23 billion at the time of their IPO.

The pundits and talking heads gravely warned that investors were crazy to pay 230 times the prior year's net income.

They said Google was a "one-trick pony". They said Google could never grow into that insane valuation.

It was a bubble, they said.

Why didn't foolish speculators learn from the dot com crash, or from the Dutch tulip mania?

Maybe today's wise men are right, and the cryptocurrency bubble will burst in a spectacular bonfire of hubris.

Or maybe they aren't really wise. Maybe they only know what they know, and can't understand what's right in front of their faces, just like they couldn't understand what Google could become.

I was rooting for them back then. Web OS was truly second to none at that time. Really too bad.
I think there is a great truth to what you said, but the reduction of Tech to just media hides a set of critical and novel dangers in doing so.

Tech provides a new set of tools - both finely grained, invasive, and mass produce-able - which target areas of human existent earlier protected just because of how arcane and nebulous they were.

As human beings, we have many tendencies that are unguarded for buffer overflows, or malicious code injections.

With these tools, and corporate/shareholder incentives - firms and teams will run amok.

Its no longer just 1 way media, its now very close to mind invading media.

Sadly the only solution seems to be to ditch the smart phone whole.
It will be. When we're able to manufacture them in large quantities and with few imperfections. Give it time.
Sure, your right - I was just trying to say that something was ringing true in his statement ... people finding it too expensive to learn stuff like this, meanwhile the company trying to do it not making enough money to stay afloat.
Then it's dead out of the gate, almost every trucking company in existence does in house repairs due to cost.
Yeah. And arguably this is intentional behavior due to a consequence of ARM's business model, where the SoC vendors all license the same IP and then need to "differentiate" (create incompatible improvements) against each other.

This isn't anywhere near as impressive as one might think: a Veyron has a pretty bad drag coefficient because of the amount of cooling intakes it has (turns out cooling an engine producing over 1000PS takes a lot of air).

Tesla will be selling into a very complicated industry. You think enterprise sales of software are hard, just wait.

Tesla say their system includes all the functions necessary. I haven't seen a list but I doubt it. Even if they do it will literally take enterprise integration projects to hook them up to the largely bespoke systems used by existing trucking company backends.

(E.g. 20 year old ADP systems)

I thought this was going to be 'The VR Thread.'

I still don't entirely understand why virtual reality didn't really catch on. I think there were some very poor business decisions by Facebook which were treating it as a success before it had even launched -- trying to ring-fence a platform, both hardware and software, whose early demographic is going to be entirely high information users seems a very questionable decision.

But beyond this, I don't really understand why it didn't catch on. The first time I tried it I was hooked simply due to the issue of presence. Though perhaps the fact I ended up never purchasing a device answers my own question -- I had no interest in a Facebook driven platform, and the price point to get involved with VR for things like the Vive did not mesh well with the availability of software, as well as the fact that hardware tends to rapidly iterate.
Also hacker dojo mentioned that they are willing to accomodate the needs of techshop refugees (they're basically the only serious space now all the way from SF SJ). They have a small space now and if people pitch in a lot more can happen (equipment is quite cheap when 10 or 20 people pitch in).

They had no choice but to expand. They had a fairly large corporate office, which needed income from a lot of sites to cover the overhead. I was thinking about investing and got a good look at the financials - only the three Bay Area shops were profitable. Bottom line, they overestimated how many makers out there are willing to pay $150 per month to support their laser cutter habit.

I'm a product manager at a telematics company. I've talked to a lot of folks in the long haul trucking space, from drivers to back office folks to service managers. I'll be surprised if this truck catches on. The trucking industry has a huge urge to do everything themselves, all the big guys have full service garages in their many yards across the country. This truck seems essentially unserviceable by anyone other than Tesla, which will be a showstopper for many of the big guys at least for a while.

I will say that I'm impressed by their charging numbers if they can hit them though. Fuel is a huge concern for carriers, they reroute to save a cent on the gallon constantly. Getting enough super chargers in place will be key for these things.

Also, as a side thought: they could have had a much more impactful reveal by having one of the big carrier's trailers hitched to that thing. Makes me wonder how much they even went and talked to their potential customers, especially drivers, who are very...particular...about their machines.

I guess the underlying assumption is the person in charge would retire or become unavailable with some deliberation and planning. Somebody gone due to accident is entirely different thing.
That is the point of convoy mode, elsewise it would cost about the same as 3 trucks minus a little drafting.
