The bulk of my mainframe exposure was with z/VM, but you're right, those systems are fascinating. I've never understood why IBM doesn't provide hobbyist licenses of z/OS and z/VM for individuals to learn on. Of course, the software would be run on Hercules [1] emulator and not a real mainframe. Even so, it would be a great avenue for people to learn about the mainframe software environment and maybe even help with the mainframe skills shortage.

Big congrats to Tracy, Ralph, and the whole team!
The left thinks bad corporations are responsible for the ills of society, while the right thinks bad government is responsible. I think we just need to understand that A. both sides of the bribe are wrong and B. big is bad.

I don't know the solution for this - absence of government just leads to less restrictions for corporations, and absence of corporations will mean that worse corporations will be tolerated by the market.
> without noticeable results.

To make an analogy, consider that hospitals dump millions of dollars, and physician hours into their trauma wards. Yet, so many of the patients in them keep dying!

Clearly, the rational thing to do is to declare that trauma treatment is a waste of time and money, and is not achieving meaningful results. We should cut physician hours, and re-allocate them to some other area of the hospital, that has a better survival rate. /s

Or, alternatively, consider all the efforts you put into testing and code reviewing your code - yet bugs still slip through to release. If all you do is count the number of bugs that make it to release, with no baseline, you may conclude that all that testing effort is not having noticeable results. We should shut down the Jenkins server, and just let any dev submit whatever we want, without any review.

The problem is that as long as you see homeless people in your city, you will think that there are no noticeable results to these programs. That the situation might be twice as bad if those programs weren't in place... Doesn't really cross the mind.
Using ln as our utility, at time N we get:

E[ln(X_1*...*X_N)] = sum E[ln(X)]

So kelly happens to maximize this expected utility by construction since it was derived by maximizing expected log of one round of betting (E[ln(X)]).

But if we use square root as our utility instead:

E[sqrt(X_1*...*X_N)] = prod E[sqrt(X)]

We would maximize this expected utility by maximizing E[sqrt(X)]. Going through the same calculus we can see that we don't arrive at kelly.

Where did I go wrong?

When those vids were first made I thought it wasn't very good at making a point because, a guy walking up to you with a camera and just sitting there with it is obviously quite creepy.

But why is it creepy?...because I don't know what he'll do with that video and it just establishes a weird dynamic to the situation.

But then why am I okay with a camera in the ceiling?

I suppose the alternative would be actual eyes, say if a convenience store had the budget for that, an equivalent to their ceiling-cams would be a security guys watching you and everyone else as they shop.
Man, I can barely understand any of this. Is there a more ELI5 type explanation anywhere?
I think you're conflating "child pornography" with "child rape" here and that might not be entirely fair. Ignoring things like 17 year olds sexting, my view of CP is that it's evidence of a crime, but shouldn't be a crime, and certainly not at the level it is now. The biggest harm - the rape - has already occurred. Someone funding it is one thing - that's almost certainly conspiracy to commit that crime. But possession by someone completely unrelated to the act?

Just like videos of people being graphically murdered, for instance. I'd put 3guys1hammer up with anything else on the internet in terms of "should not exist", but that doesn't mean I think it should be illegal to possess/distribute/view.

The bots would just get good at getting around the bot block.

Are you sure you want to accelerate this arms race?
Really fast editing features. I have found there's no real winner between Vi(m) or Emacs - I can use both although I'm more used to GVim.

Shortcuts in either editor allow quick editing compared to non Vi(m)/Emacs editors.

Also, I have a finely tuned tool-chain outside of GVim that (so far) does what I want better than what IDE's provide, depending on the language or target platform.

(I still use IDE's with java, for example)
These people/companies are far and few actually, and they can decide to eliminate such mechanisms. The bots have used the lazy nature of humans to make a shortcut for economic advantage. It has uncontrollably spawned the culture of link baiting and downfall of truth and investigative journalism. Remember that humans first built the social sharing feature before bots showed up. Eliminate the bots and you’re only left with human social sharing on equal footing.
But someone has to pay? Broadly speaking either

1) The businesses pay to get their human resources to work

2) The travellers pay or

3) Central taxation pays

So who should pay in New York?
> The left thinks bad corporations are responsible for the ills of society, while the right thinks bad government is responsible.

Complete hogwash. Neither side thinks this.

The left certainly doesn't think that "bad corporations" are responsible for the "ills of society". "Bad corporations" are simply one of the "ills of society".

The right doesn't actually oppose "bad government" at all. They are perfectly fine with foisting bad government on everybody else as long as it comes from their "team".
I am afraid that you have not understood the paper.

a) You do the measurement first on the "screen" side (and project the quantum state of the pair of photons according to the measurement, the "extra universes" disappear). You do then the measurements on the "idler" side (and project again the quantum state according to standard QM).

b) You modify slighly the setup to reverse the order of the measurements. You do the measurement first on the "idler" side (and project the quantum state of the pair of photons according to the measurement, the "extra universes" disappear). You do then the measurements on the "screen" side (and project again the quantum state according to standard QM).

QM predicts that the outcomes in the original experiment (a) and the "reversed" experiment (b) are the same. And those predictions are verified empirically.

>> [1] Most salaried employees don't do unpaid overtime, period.

At least half of tech workers I know do unpaid overtime. Almost all are on at-will contracts where they can be laid off anytime and I know almost none who have lifetime-final-year salary pension plans.
I'd like to see a technology explanation (in gory detail, and open sourced would be better) for how you keep the genome data ephemeral and secure and how you comply with HIPAA laws as well as the FDA. This software has features for which you very likely need to submit a 510k and associated regulatory paperwork, especially if you provide the data to a doctor to use to prescribe any sort of medical care.
This is my guess: Doing enterprise requires significant amount of 1:1 contact. You need thousands of people dedicated to each of the 50,000 or so top accounts. These folks do site visits, gather info on legacy stuff, try to figure out your requirements, connect to dev/PMs from core team, help you do sizing, convenience CTO et al about benefits, take your phone call at 2AM so on and on. Doing enterprise is mainly about creating, training and managing vast sales force in financially efficient way. I suspect GCP hasn't focused on this part much. It's very capital intensive operation and if not done right it can drain your balance sheet very quickly. For enterprise related businesses this is about the singular skill for an organisation that matters.
Postgres maintains 5 years worth of major releases, not more. After that no more fixes for data corruption, security issues etc. IOW, using that old a version of postgres is careless, and might even bring legal liability after an intrusion (or just data loss).

Yes, that's what I was aiming at. You can have a passive majority stake (you don't work for the company) or employment at the company with a minor stake. Note in the later scenario the majority stake must belong to an American citizen and as such you will need someone you can trust and who is American to go that route. May still be feasible for some folks but need to know these caveats before moving to a new country with your dreams.
It strikes me as somewhat ironic that Nature would public this given that they recently tweeted:

> Editorial: The US Department of Health and Human Services proposes to establish a legal definition of whether someone is male or female based on the genitals they are born with. This proposal has no foundation in science and should be abandoned. [1]

That last sentence just absolutely boggles the mind and I'm not entirely sure how this journal retains any semblance of reputation when its editorial board is so clearly willing to put ideology over science.

And vendors who put ECC on the data paths but not on the cache itself, on the assumption that check it while it is going in, its a cache so it is short lived, and you're window is small enough to meet your reliability goals.

That goes out the window when you sleep though because you don't know how long you've been waiting to restart. And the P(bitflip) is a function of time. If you sleep too long you are non-spec compliant for silent data corruption, and since there isn't a way to know how long you sleep, the only "safe" option is to invalidate the cache and reload it.

Sad but an understandable approach. The downside is your wake from sleep is slower by the amount of time it takes to warm up the cache.
This behavior evidently started with Zeno of Elea's run on logic through reasoned argument. He's the reason we have the scientific method, basically.

Fortunately, the scientific method produced technology that allows me to post this comment. Unfortunately, limiting a culture's philosophy to only discussing things we can attempt to disprove results in limiting the ability to discuss something as if it were true, before we know it to be true by proof.

Example: I believe ʻOumuamua was a spacecraft. Can't prove it, but can't talk about it as a truth either, which sorta sucks given I figured (when I was a kid) aliens would be here by now. ;)
> Here's an awful lot of snark about iOS slowing down with each successive version, but I'm not at all convinced it's universally true. (Again, anecdotally, I'd say iOS 7 and 9–11 were guilty of that.)

It's not universally true. It's mostly true, with a couple of outliers (namely iOS 9 and iOS 11). Most of time, major iOS upgrades slow down older hardware.

I wouldn't necessarily have a problem with this, if not for the fact that iOS downgrades are literally impossible (outside a small window of time). Install an update and discover your phone is too slow? Either learn to live with it or buy a new phone.
Well, serial killers don't kill almost all the time also. Reminds me of that Monty Python sketch where the army guy tries to reassure the interviewer by saying there's "almost no cannibalism in the British Army."
90% of the working world has at best indifference and at worst outright hostility to technology, and research firms are IT equivalent of the Gell Mann Amnesia.

This seem to be the case, the author don't understand that FOSS is usually built by the communities of people that share the same fundamental values (he can call them fundamentalists for all he wants) but it doesn't make his arguments correct. When he complains that FOSS community doesn't embrace the proprietary software - how exactly does he imagine this to be done, no one dictates what software we should use so this discussion is completely nonsensical. This whole idea is like someone would go to the vegan party, bringing meat there and then complain that no one wanted to eat it. Just this unwarranted complaining is enough to persuade many people that could have bought his software to stay away.

Thank you for writing this, I enjoyed reading it very much.

Silly question but have you tried an employment agency? Considered immigration? Fairly certain you’d live a very decent life teaching English to foreign students in Australia.
I just wanted to say thanks for responding :-) The resultant thread was quite interesting if nothing else. But I also appreciate the advice.

I think it's really interesting how modes of communication can throw you (or at least me ;-) ). I seem to evaluate the content by the mode of communication, which is really incorrect. I suspect it was a coping mechanism I used when I was young to quickly sort the wheat from the chaff.

What others have said about your post is true for me as well. When I look at it superficially I think, "What does 'become unstoppable' mean in measurable terms". Well, it doesn't mean anything because it is not actually possible to become unstoppable in this context. You can always be stopped. But I think that leaving it there is not a good idea. The meaning of a sentence is not in the words: it's in the actual meaning that the original person intended to convey! So if I don't understand what you intended to convey, then I have missed the point entirely.

I think this is what I'm slowly learning, so I appreciate your contribution to that learning.

As for the 'why', I have a very good 'why', but the thing that is stopping me is probably that I just don't want to do it. Several years ago I thought about starting a brewery. I had the money. My friend who owned an empty factory even offered it to me for zero rent. I had the business plan. Everything was ready to go... and then I thought, "Wait a minute... working in a brewery. That's exactly the same as working in a factory. No matter how much I think making beer is cool, I don't want to work in a factory." Then I thought, "I can hire people to work in the factory. But what will I do?" And I thought of all the jobs that I could have at a brewery and I didn't want any of them. So I canned the brewery idea :-)

So for me, I think to be "unstoppable", I really need to find a job that I want to do at my new company. This is probably the biggest stumbling block I have.

Anyway, thanks again!
The MTA spends over $10 billion per year on labor, much of it redundant (e.g. two drivers per car): http://interactive.nydailynews.com/project/mta-spending.

People say "oh, but diverting tax dollars from MTA, etc." The NYT pegs that at about $1.5 billion over two decades (since Pataki). https://www.nytimes.com/2017/11/18/nyregion/new-york-subway-.... That's $75 million per year, a drop in the bucket in comparison. About enough to build a mile of subway line.
Isn't that what I was alluding to?
It's about as meaningful as asking 9 people in the same, small, rural town if they like going to the library, then concluding that x/10 people, in general, like going to the library. Maybe that particular town has a really shitty library.
I think you are on to something about shared dependencies, but have trouble thinking about the impact of these might be. They share more similar cosmic positions in the galaxy, perhaps have more similar chemical compositions, they both share the same sun. Is that enough?
General relativity holds that the universe has no “center”, either earth or sun. even more surprising, is that unlike newtonian physics, general relativity says the universe doesn’t even have a single “clock”, and what you observe in astrophysics depends on where you observe it from and how fast you are travelling when you observe it. the speed of light is constant, and space and time will bend in order to maintain the observation that light is always a constant speed.

The location, and speed with which you are travelling is what general relativity calls a "frame of reference", and none of them are "correct" or "incorrect", they're just predictors for what observations will be possible from that frame.

then the weirdest part is that one of the consequences is that planetery bodies are large enough for that “speed of light must remain constant” rule to matter in a particular way as to generate a warping of spacetime around them, the geometry of this warp perfectly explaining gravity. or put another way, we stick to the earth because time runs slightly faster at our heads than at our feet.

I took the array approach which should be still faster because it avoids the hash calculations. Just build an array Char[65536] containing at every index i the character the character i should be mapped to. Rotator.Rotate() then simply becomes the following where Rotator.map is the precomputed array. Probably very similar to an implementation using a hash table. I also got rid of the string builder but did not profile the difference. If one uses a string builder it would most likely help to specify the capacity in the constructor call so that the internal array does not have to be resized repeatedly as the result is constructed and grows in length.

public static String Rotate(String input)
{
var result = new Char[input.Length];

for (var index = 0; index < input.Length; index++)
{
result[index] = Rotator.map[input[index]];
}

return new String(result);
}
Boy they sure tried to reel my business in. However, having done some time in the past, I knew a mafia-like scheme when I saw it.

They basically wanted full control of my bank account and my credit card processor, and wanted the loan repaid at $100 a day and at a 50% cost.

The guy calling me got really pissed when I told him I could increase my product prices by 3% and raise the loan amount they offered over the same period as the loan, interest free.
In typical HN fashion, my comment was "flagged" but cannot be refuted.

The point stands: California is a Democrat monopoly while having the worst infrastructure, homelessness, and the nation's highest poverty rate.

But not one HN reader can respond factually.
It's not strictly theoretical. The original comment clearly was calling out the Android and mobile ecosystem in comparison to other hardware devices. If I dig out my iPhone 3g, I'm not getting anything close to the latest iOS on it no matter what I try. I can pull out a laptop from the same time period and install quite a few of the top linux distros on it.

Any Apple device is a specific combination of hardware and software that Apple chooses when to stop supporting, and you have very little recourse. Apple has generally been better at providing support to older devices than Android (on average), but in the end the situation is fundamentally the same.

In the case of images of child sexual abuse we know that's true. We know people trade images to get access to websites, and we know people need to trade newly created images to get access to some websites.

We also know that the idea these images are out in the world is something that causes trauma to the victims.
I think though that just proves the point that there was so much low hanging fruit back then- and not so much now. You’re not going to discover something as fundamental as electricity again, for instance.

Since we're using `-o` already, we might like the equivalent "longoptions" form:

```
set -o errexit -o nounset -o noclobber -o pipefail
```

But `pipefail` isn't part of POSIX and will fail in dash, tcsh, and friends, so it's arguably better to go ahead and use your shell-specific builtin whenever possible---`shopt` for bash, `setopt` for zsh, etc.

```
shopt -s -o errexit nounset noclobber pipefail
```

For that matter, if we're using shell-specific features, we might as well use the appropriate bang pattern:

```
#!/usr/bin/env bash
```

or similar. It's also really nice that Shellcheck differentiates between shells based on bang patterns and changes it's behavior accordingly.

Also, I can't help but mention the bash unit testing framework, BATS!
