What Is a Good Metric?
The fact that trend following strategies are becoming less effective could be interpreted as a positive thing implying that markets are becoming more efficient, as trend following shouldn't work in a completely efficient market.

Trend following strategies are pure market followers and are not based on fundamentals, therefore they do not bring any new information into markets and are unlikely to improve the efficiency of a market.
>If we want behaviour and concern to be one consequence of the other, we need better education and more government action.

I think government action would more align with the realities of better education. The better education aspect, however, relies on people being willing to keep-up with the growth of technology after their compulsory education ends; which is, probably, going to be your hardest sell.

For those of us, for whom technology is a an every-day necessity and/or the source of our income, that premise in the interests of continued education in technology seems second nature. However, if you compare that to doctors, they're primary concern is keeping up with medical trends; so, this might be a harder "sell" to them.

Instead, much like other professions have governing bodies, technology should probably have it's own. I'm thinking along the lines of things like doctors and medical review boards or lawyers and the BAR.

However, there is another caveat that the governments benefit from: Ineptitude around technology is what governments actually benefit from. Telling the governments that they should care more about education around technology and creating laws to protect basic rights is going to be a hard-sell to some of them. Take the current issue with the US law versus the GDPR for a principal example.

I don't pretend to have an answer but, to me, it generally comes down to whether the government is far more concerned with the welfare of itself than the welfare of people (in general).
Yes, that and improving efficiency of markets, the go to arguments for wall Street types. I used to be a sell-side trader, allocation of capital was the last thing on our minds. It might add value to the economy in the long run but I'm pretty sure it's way too crowded now with little marginal benefit. If we took the underlying technology and man hours used to make something more useful I think the world would be better off. Something is seriously twisted in its current state
The State of Open Source Security – 2019
I have done some research, and it sounded like you're overstating or making false claims, so I'll called you on it. "Do your own research" is just another easy way to dismiss criticism. I can't prove that no researcher has ever been banned on ideological grounds. You made the claim that this is the norm, I don't think it is, so I simply asked for a reference.

Thanks for providing the above citations though.

I've indexed the statements I have a problem with, because you seemed to have missed the last and most egregious one.

1. Even in many "scientific" fields, standards are so low that most published research is wrong.

This claim seems to be supported by evidence. I think it's important to add that while we should encourage higher standards and alternatives to p-values, replication is a critical part of the scientific process. Biases will inevitably creep into study design and analysis. This implies that even with extremely high standards, a significant portion of studies (hopefully not the majority) will still fail replication, because it was conducted by humans.

Psychology studies are notorious for this. I don't think they represent the majority though. I could point to particle physics that have a convention of five-sigma (99.99994% confidence). Let's not resort to cherry-picking.

2. And in much of academia, evidence is less important than ideology

3. research and researchers are banned not because they are wrong, but because their ideas are unacceptable.

I didn't see any citations backing these claims.

In your added citations you point to a correlation between conservatism and academia. Implying that the difference is because conservatives are forced out of academia is jumping the gun. I have an alternatives theory: people that think science is important don't want to associate themselves with group that are considered anti-scientific (public perception is key here).

There is no place for _any_ ideology in science anyway.

> In decisions ranging from paper reviews to hiring, many social and personality psychologists said that they would discriminate against openly conservative colleagues. The more liberal respondents were, the more they said they would discriminate.

This is flawed, they did give participants the option to abstain from picking a side. "Moderate" is also a position.

Sure. My goal is to instill the mindset far in advance of handing down any sums of money. Basically, if I don’t observe the type of behavior I’m looking for such as managing your own finances in an intelligent manner, I’ll probably do something else with that money or just let it accrue interest until he is ready.
On the other hand, why should brilliant people work for modest salaries, creating wealth for others?

The stock market is basically a transfer of wealth from one person to another. For a good strategy to work, someone has to make a bad strategy. If everyone gets a good commodity strategy and applies it you will end up in a stalemate. Maybe not instantly but somewhere down the line.
> Businesses are wasteful because that's the natural status of a bureaucracy. They aren't throwing away money on infrastructure because they are unaware, they are spending more than they potentially have to because infrastructure isn't their core business.

That's not true at all. The "isn't their core business" argument is meaningless and absurd. Any company, big or small, does not want to waste 300M dollars on something they don't need, whether it's their core business or not, particularly when said company is still far from turning a profit.

> That's such a tired argument. Just because they could save money doesn't mean it's a good idea

You are aware you're stating that baseless assertion on a discussion on how a company which is burning through cash and looking for investors is needlessly wasting 300M on infrastructure costs.

> No, the fact that you think this is a "problem" is the problem.

Needlessly spending 300M dollars is a problem in every single business in any corner of the world. I have a hard time understanding how someone can throw around the baseless assertion that this sort of inefficient while operating at this particular scale is not a problem, and pointing out this problem... is the problem? That's crazy.
Do you have any suggestions on how? I do not doubt it can be automated, but it is one of few vulnerability types I do not have an intuitively understanding on how it should be done.

Manual alignment is often used as a poor man’s elastic tabstops.

I think there’s a chicken-and-egg situation with monospaced type and programming. Programming was a thing before digital proportional typefaces were a thing, so some people came to rely on the fixed spacing to treat their source code as a 2d grid rather than a 1d buffer. This in turn made it more difficult to switch over to proportional typefaces despite their advantages, and at some point code == monospaced was just taken for granted. Another issue that comes from mistaking your code for a 2d mosaic is the dogma of dictating a maximum number of characters per line, instead of the more reasonable approach of using whatever expresses the structure of the program most clearly, and relying on line wrapping to make sure it’s all visible.

FWIW I use proportional fonts, and 95% of the time it’s completely unproblematic. Fortunately I rarely work with code that uses manual alignment. It’s usually the occasional ASCII diagram that forces me to temporarily switch over to fixed pitch.

> If you trust it blindly, it’s not science, it’s a cult of title and rank.

A true but slightly inflammatory first line for something that everyone does. There aren't enough hours in a 70 year lifetime to make every decision using critical thinking - everyone uses title, rank and social proof for shortcuts.

My experience is that there are many people who claim to be arguing from scientific evidence when they are in fact not - and I think it is because they don't realise that (a) being smart is no defense whatsoever against using cognitive shortcuts and (b) thinking non-critically is actually likely to be a better personal strategy for most decisions.
That maybe, possibly, there is a non 0 percent chance that maybe Amazon are using the data to help their facial recognition system (doesn’t the AWS Contract forbid Amazon using customers data this way with out explicit permission? It’s been a while since I’ve read the whole terms for AWS. Just to clear what I mean is Amazon automatically just processing everything ever uploaded to anything on AWS for their own benefit without the permission of the AWS Customer or the permission of the person who is “in the data”).

But then again their is an non 0 chance that Amazon are not recording everything we say via their echos so they can simulate our voices and ring up all the local shops and tell the owners to go fuck themselves so we have to use amazon for everything...

Either that or the implication is that because the police are using S3 to store bodycam footage, they MUST be using their facial recognition system too.

Edit: Jesus fucking Christ HN, it’s a bloody joke, I thought the part where Amazon are calling owners of local shops would of given that away. Guess I’ll have to be more explicit :-P I’m mocking the article because they state that their is privacy implications because they use AWS. Well their are privacy implications if you use any vendor or even if you self host.
Assuming all you want to do is make some graphs, almost every alternative is better. Matplotlib is like the opengl of plotting libraries, there's almost no abstraction, you have to create plots in an imperative way and it's extremely verbose.

A plotting library focused on useability should let you specify what you want in a declarative manner, then get out of your way. Ggplot2 being the prime example.

I've been freelancing for a long time but never automated invoicing people up until recently.

So I combined grep, cut, paste and bc to parse a work log file to get how many hours I worked on that project, what amount I am owed and how many days I worked. I can run these analytics by just passing in the log file, a YYYY/MM date (this month's numbers), YYYY date (yearly numbers) or no date (lifetime).

Long story short, the working prototype of it was 4 lines of Bash and took about 10 minutes to make.

Now I never have to manually go through these work log files again and add up invoice amounts (which I always counted up manually 3 times in a row to avoid mistakes). If you're sending a bunch of invoices a month, this actually took kind of a long time and was always error prone.

Ok after a bit digging:

- German police signed a service agreement (probably with Motorola) as the model of bodycam is Motorola Si500. [0][1]

- Motorola is one of the service providers working with Amazon. [2]

"Motorola offers a digital evidence management solution that simplifies the way your agency captures, stores, and manages multi-media content. The solution includes the Si Series Video Speaker Microphone that combines voice communications, body-worn video, still images, voice recording and emergency alerting into one compact, easy-to-use device. Integrated with Motorola’s secure cloud-based CommandCentral Vault digital evidence management software, this solution is streamlining technology and reducing costs for law enforcement everywhere."

- They have some short nice video about their security [3]

- Basically it is totally cloud solution, although it has client side encryption, if you think Amazon can be compromised, rest of security falls apart too.

> [...] Many of the most brilliant human beings of that era worked for very modest salaries, and seemed content to do so. I wonder why it is that nowadays the "smartest" people tend to work in tech or finance and mostly pursue wealth. A few possibilities:

This is something in essence that some of us at MIT get told by faculty upon telling them that we want to go into industry. Behind it, though, there is often a fair bit of arrogance: many of them can not truthfully say that they would not do the same if they had to accept an academic position at a "tier 2" place, long postdoc, etc.

That said, the spirit of the point is perfectly fine. My own personal answer is that I have no personal issue with the compensation in academia; the associated "bureaucracy" which is far more severe today (paper/citation counts, and other things of even less significance) turns me away. It remains to be seen for myself how "industrial bureaucracy" compares with it. However, everyone I know has told me that in terms of personal happiness/fulfillment, people who leave are usually much better off.

I mention this as I had a conversation where someone essentially assumed point 1 or 2 rather than the distinct reason above.

The hyperpartisan politics in the U.S. has been fostered since long before the internet. On the right, "rage radio" has been big since the early 90s. After listening to conservative outrage, it's hard to then listen to the other side of an argument and think "they may have a point."

Similarly, left wing comedy-news shows make fun of the other side. When you see the other side as ripe for ridicule, its hard to then say, "but they may have a point."

Source: I've known many people on both sides, and it always saddens me that discussions don't boil down to "let's both look at the arguments from both sides." Instead, there's an emotional "the other side is nuts" response that blocks all attempts at even discussing things fairly.
I like the opening of this aricle. It almost mentioned all the interesting books about the folklore history of computing. All the books mentioned in this article are worth reading.

> Extant histories of the internet favor either heroic or deterministic narratives. On the determinist side, we have Paul Edwards’s The Closed World (1996), Fred Turner’s Democratic Surround (2013) and From Counterculture to Cyberculture (2006), John Markoff’s What the Dormouse Said (2006), and others that describe the internet as the result of collisions between large-scale Cold War policies or zeitgeists. With some variations, these narratives portray the digital revolution as born from the improbable marriage of countercultural hippie experiments and the military-industrial complex.

> On the heroic, individualist side, we have Steven Levy’s Hackers: Heroes of the Computer Revolution (1984), Katie Hafner and Matthew Lyon’s Where Wizards Stay Up Late (1996), Michael Hiltzik’s Dealers of Lightning (1999), Walter Isaacson’s Innovators (2014) and Steve Jobs (2011), Leslie Berlin’s Troublemakers (2017), and Adam Fischer’s Valley of Genius (2018), whose titles speak for themselves. Histories in this genre extoll the whimsical personalities and talents of digital entrepreneurs and inventors, of whom Jobs is the prime exemplar. Some do acknowledge the contingencies that facilitated the rise of these digital “geniuses.” But overall, they tend to represent Silicon Valley as a titanic battleground that proved the superior mettle of its winners. Both extremes are tempting in their clarity; both make for a gripping story. Occasionally—as in Liza Mundy’s Code Girls (2017) or Margot Shetterly’s Hidden Figures (2016)—a simultaneously individualist and Marxist approach unveils underappreciated digital counter-heroes.

Rings way too true for me atm.

My current workplace is currently struggling, because one of our application stores something like a combined 300G of analytics data in the database with the application data. Modifying the table causes hours of downtime because everyone claims that backwards compatible db changes are too hard. And everyone is scared because with more users there's "so much more analytics data" incoming. Yes, with 300Gb across 3-4 years.

And I'm just wondering why it's not an option to just move all of that into one decently sized mysql/postgres instance. Give it SSDs, 30 - 60Gb of ram for the hot dataset (1-2 month) and it'll just solve our problems. But apparently, "that's too hard to do and takes too much time" without further reason.

Based on my a limited view, if a new grad majored in something other than computer science+ but took some programming classes he or she is overwhelmingly likely to be most comfortable in python. However new grads with a cs degree+ are likely to have at least some and often quite a bit of exposure to java.

I agree with the title! But the article itself is fluff & platitude.

Anecdotally, when I make bad decisions on the job it's almost always due to my emotional state. Whether it's the stress of an impending deadline, lack of sleep, feeling of inferiority, etc.

Even when I'm aware of a dangerous emotional state, it's difficult to make good decisions. Proactive prevention (get enough sleep, exercise, meditate if you're into that) has been the only solution for me. I'd be curious to hear more preventions and especially interventions that work for others.
