I've been using cold water at the end of my showers for a while now and it doesn't feel painful or even uncomfortable. Quite the opposite. So, your point may follow but not exactly in the way stated.
I partly agree with you, but I think people are also interested in how a sudden and unexpected departure would play out. If Linus Torvalds wanted to retire and spend the rest of his life diving rather than maintaining the kernel, I expect there would be a planned transition.
node.js security is hard to get correctly.
Even if you keep your dependencies up to date, your application might be pretty vulnerable unless you know what you are doing.

This is because:

1) frameworks are minimalistic and they give you some large room for error.

2) javascript is very dynamic, and it is time consuming to validate types... unless you are using something like typescript.

3) people tend to use node for orchestration layers/api gateways... and focus their security on the underlying API. But exfiltrating at the orchestration layer is as severe.

I teach this stuff using a stm32l476vg discovery board at the Australian National University[0]. I re-wrote the course earlier this year to use that board (previous incarnations used a homebrew teaching architecture - emulated in software only).

It went really well - although there are always rough edges the first time through a course. Next year, I'm going to tighten things up (one of my jobs over the southern summer before the course runs again in Feb 2018).

Happy to answer any questions that folks have.

You can short bitcoin just like you can short gold or yen or pork bellies or Treasury bonds.

Be prepared to put up some hefty margin, though, because shorts have a tendency to get eaten alive.

And you can still sell cryptocurrencies that you own, why exactly is shorting an asset required to value it fairly?

Does anyone argue that difficulty in short-selling residential real estate prevents it from being fairly valued?
Tesla is promising massive cost savings over traditional diesel trucks, so that might change the service equation.

I do, hence my speculation about putting the NVMe in firmware instead of hardware :)

(Colin's speculation in a peer reply is also reasonable -- personally I've seen enough errata in "off the shelf" IP to shudder at the idea of anything in silicon that doesn't have to be, but fundamentally I'm a SWE, so that would be my take, wouldn't it)
Something consumer driven that makes a $200 billion market even begin to make sense would be a start.
More likely to AIs, although the medical lobby is quite strong and will probably manage to get the benefits of AIs but still require a radiologist to certify.
As kobeya points out https://news.ycombinator.com/item?id=15719171

they are not the same thing

they do less; the software is restricted, especially on iOS, there are _rules_ set out by the manufacturer about what is acceptable in software on the platform, both thematically and functionally. An app generally can't interfere with other apps, it can't be a dope wars style game about drugs; there are a lot more caveats, but I am far from aware of them all. For a long time you couldn't get a compiler or interpreter on iOS, so you couldn't use your "computer" to make more software... so it wasn't general-purpose at all, since you by definition couldn't change its purpose without the ability to make new software.

Why can't you short bitcoin, will no one lend bitcoins?
It might do better than 300mph if they can build tires capable of holding the car down in one piece. I’m not kidding, I do genuinely suspect that’s a possibility given the figures they announced. I’d wager that’s part of why they wouldn’t commit, because they aren’t sure what it can do yet and have been working with Michelin or Pirelli to find out.

It’s hard to comprehend 1.9 pushing a battery pack. If that thing doesn’t break 300, it’ll flirt.
And of all gold that's mined, what % of it goes towards industrial usage for its amazing physical properties?
Yea, for sure. I suppose that could either be a staffing problem, or demand outstripping (tool time) supply. In the latter case - if there was space/power available - perhaps they could have gotten a second tool. Or from an economics perspective, raise the rates until the demand cooled off a bit. (Of course that kinda sucks as a member, but it also sucks if you're paying and can't get access time to use the tools you want, so it's a bit of a balancing act)

Ask HN: How to improve my automated testing skills?
I understand the fundamentals of unit and integration testing. I try to use a balance of them in all code that I write. However, specially with languages such as python and JavaScript, I am constantly stressed about breaking the "integration" between functions at some boundary which isn't being tested in my test suite, even though the suite has a high coverage.

I have recently subscribed to Destroy All Software screen-casts where the speaker does demonstrate some similar scenarios and tries to resolve them. Are there some similar books/ videos/ open source projects which I can refer to, to improve my testing process and suites?
Could you please not use uppercase for emphasis? It's basically yelling. Asking not to do that is one of the original HN guidelines: https://news.ycombinator.com/newsguidelines.html. Imagine this comment in all caps and I'm sure you'll understand why.
That's what fixed precision types are: integers + a scale factor -- whether it's cents, mils or something else.

Javascript does badly need a native fixed precision type beyond "everything is a double" or some web assembly hack.

And I like Javascript, but this is a real problem.

Google is a real thing. The impression from a lot of people isn't that Bitcoin is "actually" worthless, but that it's not currently being used in society in a way that validates the high numbers we're seeing.

Shorter thesis: Bitcoin right now is fueling Bitcoin startups, but not much else. Google was search.

You're reading too much into the statement in my opinion. "What if XYZ got run over by a bus," is a colloquialism that simply takes the farthest position in order to talk about the worst case. It just means, "what would be the fall back position if everything broke and vapor came out"?
A safer way in my opinion is to:

0. read module license

1. checkout the module to be patched

2. modify it

3. do "npm pack" to save a tarball

4. set the dependency version in your package.json to the tarball. and make sure to the tarball is available during build time.

5. report the issue in their issue tracker for long term fix.

In contrast:

with this "quick fix", the dependency can change, or the transient dependencies can change. This would cause the quickfix patch to not apply anymore.

The only way to guarantee that it won't break is to save the module and all its dependencies. Something that is equivalent to npm pack.

Finally... don't get yourself into a licensing problem. Take a good look at the license before modifying a project.
Absolutely, trouble shooting requires abstract thought and following long logical chains as to why something is failing. Cars are complex systems just like software can be, good knowledge of many different domains inside your main discipline is required to put the pieces together. I have always found good mechanics to be really switched on individuals.

True. Chat bots supply some of the functionality. In Wave you could have bots which would replace, alter, or add content based on things you typed in or some other rules. Like you could have a stock ticker bot, or one that inserted maps, or ones to do live translations.

The collaborative document editing in Google Docs improved afterwards, the Google Wave wikipedia entry doesn't mention this but I have some vague recollection of some of their work being migrated into Google Docs to improve it in that regard. That may be completely wrong though since I can't seem to verify it.

Peterffy's letter to the CME is short and fun reading.

https://www.interactivebrokers.com/download/11-IB17-1145-tp-... [PDF]

His doomsday scenario is based on the Bitcoin price rising rapidly.

The CME's volatility limits would kick in, preventing shorts buying to cover their positions. This leads to "ruin" for them and the CME, and contagion for the real economy.

He has a good point, since losses on short positions are theoretically infinite, there's no way to put up enough margin for perfect safety.
> It's hard to know where to even begin in arguing against this.

It's really not.

Encryption is all-or-nothing.

Either encryption works, or it fails. You can't pick and choose for whom it will work, and for whom it will fail.

So that frames the question, "Who is allowed to use encryption?"

This is a dangerous question to be asking, which is why it is hidden behind rhetoric by those who are asking it.

Encryption is speech.

Anyone can create and use a cypher. Such techniques were invented long before modern computing. Encrypted data is indistinguishable from random data, and possibly even unencrypted data.

Encryption is math. Cyphers are mathematical functions, whose derivations are public knowledge.

That brings us to the next question: "How?"

Either you control speech, or make math secret. Neither option is scalable, and neither option is moral.

The question on the lips of everyone in the Linux community is, "What if Linus Torvalds (affectionately known to the trade press as 'Linux Torvalds') gets hit by a bus?" Reams of virtual paper have been wasted on idle speculation about the results of what is a fairly simple experiment. We decided it was high time someone actually took the trouble to find out what would happen if Linus Torvalds were to get hit by a bus. Our preliminary findings are printed below; we hope that this study will eventually be published in peer-reviewed Linux publications such as Linux Journal and Slashdot. Well, Linux Journal.

Methodology

Our sample consisted of 200 Linus Torvaldses separated into a test group of 100 and a control group of 100. 97 members of the test group were hit by buses at speeds ranging from 5 MPH to 70 MPH. The other three test subjects ran into stationary buses on their own power. A different bus was used for each trial so as to ensure that the trials would be independent.

The control group was observed over a period of six months, in which none of the subjects was hit by a bus.

> The truth has always been fuzzy/slippery. There never was a golden age of unbiased nothing-but-the-correct-truth journalism. The only change now is it's a little more obvious.

And IMO that realization is a sort of "coming of age" that isn't in any way unique to modern generations.

Another horrible idea from the worst Administration any of us will ever live through.
I wouldn't be surprised if there is a lobbying battle that ensues after these types of vehicles become available. With transport and shipping being such large targets in regards to emissions, banning or phasing out fossil fuels will make electric semis inevitable.

I guess the question then would be how quickly the current manufacturers can supply an offering. Manufacturers with existing business relationships and greater domain knowledge would be in a much better market position than Tesla. Being first may not help them here.

Tesla has to design and develop an entire truck, existing manufacturers just have to develop the drivetrain and plonk it in established product lines with the kinks of semi transport already ironed out.

> Lower drag coefficient than a bugatti veyron

I LOLed at this one. Supercars want lots of downforce so they don't constantly go off the road and you die. They're not built for low Cd. A Toyota Prius has 35% lower drag coefficient than a Bugatti Veyron.

It's like when the "superfruit" people go "look at this amazing berry, it has 20% more vitamin C than a lemon!" Well yeah, an orange has 70% more vitamin than a lemon. Marketing wank for the uninformed masses.

> On empty 30 min of charging will get you 400 miles.

I did a double take here. To do that we're talking ~ 1000 kWh drawn from the grid in 30 min; that's pulling 2 megawatts of power. None of the existing Supercharger installations come close to providing enough power for even one truck.

It also means that on the distribution grid, a charging station for 8 semis will need a dedicated 20 MVA 33/11 kV distribution transformer, plus 4 11kV/480V transformers. Unless you manage to keep those charging slots filled 90% of the time, that's going to be bloody expensive electricity.

I think Agency is always understood to be a part of the equation - and the people with the agency are not the issue.

By analogy - If the population of a city was exposed intentionally, to a cold virus - it is not the people with natural resistance, we are concerned about.

We are glad those people are not affected, and know they are not part of the % affected by the virus - and then we focus on the people affected by it.

---

If I were to engage with your point in the spirit it is intended, there are several issues -

1) Tech recruits the best of the best. IT pays for the smartest people in the world (and this is not hyperbole), to get past agency. This is not hard core drug dealer style sale of addiction. This is candy crush, happy smiley imagery, "just one more game", style behavioral addiction.

Most people don't even know they are being addicted/affected

2) This is all at internet scale. Just on a probabilistic level, the casualties/infection is going to vastly outperform personal agency.

3) The network effects of having more people doing this, at this scale, pushes it to crisis levels very quickly. It wouldn't matter what the few immune or capable can do.
You should try surfing, too. Never had a cup of coffee that wakes me up like a wave to the face at dawn.
You are saying tech is a more powerful tool than traditional media. I agree. But the purpose the tool serves in society is a question of how people wield it, not how powerful it is.
Once conservative opinions actually start being suppressed, instead of being championed far and wide by breathless sycophants, you might have a point.

I wonder if there will be a measurable impact on accident rates.
You're right of course, but there is a reason the colloquialism takes this form as opposed to another. Colloquialisms, the intelligible ones at least, sublimate some underlying element of culture in order to communicate sensibly and easily.

This very idea of stretching logic to extremes without consideration for real world effects is very much a foundational element in programmer culture. It's born out of rationalism and certain elements of enlightenment thinking. However, this pure (im)practical reason is often applied in all circumstances irrespective of the context. After all, it's possible to reason about a person's absence without also implying the worst, and this kindness is valuable. If SV could somehow change its foundational thinking from reason + corrosive business practices to reason + kindness we'd all be better off.

In 2004, analysts and pundits acknowledged that Google had some utility, but they had great certainty that Google's potential was far too small to justify the valuation.

Today, almost everyone accepts that the blockchain is a disruptive and valuable innovation and that cryptocurrencies have some utility -- just far too little to justify the valuation.

They could be right. It's just not obvious to me that the potential isn't there, and I question how they can be so certain.

Embers are a big problem, and another one is vegetation near your house. If you have a big dry bush just outside your patio door and it starts to burn, the infrared coming off it can go right through the glass and catch the inside of the house on fire before the outside starts to burn. This is why we preach defensible space (no vegetation within 30-50 feet of the structure).
