This sounds a bit closer to the ideal of just working with respect to sun rise. It eliminates the abrupt transition twice a year and allows the adjustment to be greater or less than an hour which is good because the useful adjustment changes with latitude.

These days we could just skip the discrete changes all together and just use solar time directly.
Event Sourcing seems like the ultimate YAGNI architecture.

You make an architecture that optimizes for future features at the expense of a coherent flow for the current features that you know you have.

it's like if you made pub-sub the core architecture for your system. very actor-system like, but also probably harder to understand the runtime behavior - control flow.

No, I'm talking about GOSPLAN in last 15 years of life of USSR. I forgot name of woman (I did investigation more than 15 years ago), but it was just one woman, protege of Babaian. I forgot details, so maybe it was yearly plan, but idea remains: for last 15 years, USSR was on autopilot and bribes.
This is the society that produced Fruit Loops and Lucky Charms; the notion that it cares at all about children, or anyone else, is rubbished by the child obesity statistics. What's creepy is that we've built a society that rewards this mentality with greater power: those who are able to successfully market disgusting crap to children are "winners".

If you have a problem with this, you have a problem with capitalism. Advertising is nothing. There are people out there, right now, designing, manufacturing, shipping and deploying all sorts of lethal devices that are maiming and killing children all over the world.
Thanks for your reply.

Actually the question was more around "how do you create your models and what do you mean treating them as code", "why slurm and not something like airflow" , "what is the test/performance setup - backtesting, smoke test" etc etc

Oh I see I misunderstood then. But still, how is this a database? Without looking into it too much it seems that would either be an ORM or simply state.
That would be much better for those of us who are red/gred colorblind if it was just bolded white.

It can be quite hard to read deep red text on a black background. You don’t always have enough access to systems to change the default coloring to prevent this.
I don’t doubt any of it, but I despise the hyperbole.
It's not the body itself, it's the embalming fluid, caskets, paints, etc that make up more mass that the body that are the problem. There's nothing fundamentally more toxic about the corpse of a human vs. the carcass of a cow.
If the inside parts have more to do with the functioning of the virus (which is what one might guess from hearing that they are more conserved), could targeting them with antibodies bias viral evolution towards colds turning deadly as opposed to slight changes in their shell proteins?

> You don't see advertisements for the ballpoint pen any more

Google "Ballpoint pen" and you get a whole top row of sponsored links trying to sell ballpoint pens to me.

But sure, ballpoint pens aren't advertised on prime-time TV like products sold to 20-something trying to get an edge on the dating life (deodorant, hairspray etc.). That's an especially lucrative market, but not the target audience of most products.

> Macro-economically speaking, is this a company or industry that should keep on growing? The point of capitalism was supposed to be that there was competition in R&D[...]

One of the main points of capitalism is to decentralize the decision making about what's worthwhile economic activity to a bunch of uncoerced individual decisions.

Does that result in a bunch of money being spent on "pointless" products? Sure, but who's to say what's so important that everyone should do without it?

They could provide a plain-text website (even with ads, since the providers are probably all doing business in the EU) or link to outline.com, which would at least gain them the reputation of somebody having read a good article from them.
It just seems so heavy-handed, if your goal is that people should get off work earlier to enjoy more sun for example, why not just make working days shorter, or move them back? Why change the entire measurement?
An interesting, yet depressing story. Quite a nuanced look at a complex issue. The portaits of the homeless people involved helped humanize an otherwise abstract problem.

That's exactly my hope. Only large companies benefit from such laws (including, potentially GDPR), other smaller ones get slowed down. With gdpr, many newspaper outlets stopped access from outside of the US.
I'm sorry, but this is just wrong.

Some things should remain inviolate.

In this case, not just for the memory, but for the new children who continue to engage with Rogers' program (it will run in repeats and streaming for years and years) and experience its commercial free attention and insight.

Further, Fred Rogers was genuine. This commercial is disingenuous.

Radiation hardness is different than sensitivity to EMP. It is the eddy currents from an EMPT that build up in and burn out small traces in micro electronics.
Social Text wasn't a major venue (of postmodernism or anything else), and Sokal's hoax didn't cause a fall of postmodernism in academia. Far from it. When I left academia in 2009 it was still the dominant perspective, and that doesn't seem to have changed.

Fish's response to Sokal is also exemplary:

What sociologists of science say is that of course the world is real and independent of our observations but that accounts of the world are produced by observers and are therefore relative to their capacities, education, training, etc. It is not the world or its properties but the vocabularies in whose terms we know them that are socially constructed -- fashioned by human beings -- which is why our understanding of those properties is continually changing.

Distinguishing fact from fiction is surely the business of science, but the means of doing so are not perspicuous in nature -- for if they were, there would be no work to be done. Consequently, the history of science is a record of controversies about what counts as evidence and how facts are to be established.

Those who concern themselves with this history neither dispute the accomplishments of science nor deny the existence or power of scientific procedure. They just maintain and demonstrate that the nature of scientific procedure is a question continually debated in its own precincts. What results is an incredibly complex and rich story, full of honor for scientists, and this is the story sociologists of science are trying to tell and get right.
> Jeri Ellsworth hates this article

probably used in jest - but playing along - probably because premise of article is heavy on summoning up ethos & pathos to generate interest whereas, from what I can tell of Jeri's style, she is more centered on direct logos.

in a way, the way OP uses ethos/pathos method is somewhat deceptive/dishonest, because it's trying to get you interested in source material for reasons that are entirely make-believe.
Based on the difficulties I had implementing recommender systems, I think it boils down to two main problems:

1. Evaluating recommender systems is REALLY hard. When it comes to evaluation, recommender systems are very different from other machine learning tasks:

Let's assume the classic methodology of collecting a dataset of events, splitting it at a certain point in time to get a training and test set, and checking the precision and recall

- If your recommender system works as expected, you will influence what your users do in the future, so your test set is probably not going to represent what your users would actually do.

- Having a precision and recall of 1 is actually bad. That means your recommender system was perfect, but also useless (you only recommended stuff that the user was already going to pick anyway).

One way to address this is to just use A/B tests and try to optimize some business metric (e.g. number of purchases). This is usually "good enough", but this will make your recommender focus on sales, not on user satisfaction.

There are also some other metrics that can be used[1], but there are so many of them and some are not very practical to implement, so I guess that everyone just goes with the A/B testing approach.

2. Recommendations require an explanation

A lot of recommender algorithms are black boxes.
Sure, you can write "this was recommended based on users similar to you" when you use a collaborative filtering algorithm, but that doesn't help much.

Recommendations without an explanation are not that useful. When a friend recommends you a movie, he'll also tell you "why". Otherwise, it's really hard to make users trust your recommendations (especially if the recommender system recommends something outside of the user's "comfort zone")

I've noticed that a lot of sites have improved on this front though, and I do enjoy those recommendations a lot more.

Hm. So again, my whole rant has to do with the fact that the videos (3-4 in total?) have been independently verified to have come from the Pentagon. That part has not, to my knowledge, been debunked as independent sources have FOIA'd copies of it. Heck, you could file a request as a private citizen and obtain the same, and I encourage you to.

So what does this really mean? If you draw it down to either the video being fake or real, I can only see four possibilities and reasons.

1. Fake: this is a product of a Pentagon psyop intended to leak out and cast doubt on our enemies's intelligence, implying that we have access to top secret propulsion technologies beyond their known capabilities.

2. Fake, but conducted by persons unknown and planted inside the Pentagon. It would have taken quite an effort to fabricate because it involved two-three radar tracking stations, an entire naval carrier group, senior pilots, military intelligence, record keeping personnel. Too many of these have issued reports corroborating the observations. Way too many disconnected people to manage for a conspiracy.

3. Real. One of our enemies has access to secret propulsion technologies beyond our capabilities to counter. Enemies, because our own military intelligence was unaware of anything like this and a threat, because it clearly had superior flight characteristics as described by the witnesses.

4. Real. Question is about its origin, however. Terrestrial: are these merely shy biologicals living under the sea we've never cataloged? Extra-terrestrial: automated probes from another place, another time? Other life in the universe?

Only one of these possibilities is bland to a point of ignoring it, that being #1. Rest of the possibilities have profound implications about ourselves, and none so much as #4. It means we're not alone in the universe. So while I agree that a broken clock can tell the right time twice a day, I don't bash what I used to call UFO nutjobs as much anymore.
USA. We have no problem with communist organizations such as Antifa marching openly in our streets, nor the Democrat party's open embrace of socialism (communism by another name). There is even a push to make the Democrat party explicitly communist.
If there’s a 30 year limit, why are tombstones that are >30yrs still standing in most cases?

Products sold in China must be cheaper than those exported, so that workers can afford them. That means that standards will be nonexistent.

Otherwise, I can read dozens of dubious predictions a day for free on the financial web sites.

This works better if there are distinct escape sequences to mark the start and end of stderr output, as in DomTerm (http://domterm.org/Wire-byte-protocol.html#Special-sequences...). I created a fork (https://github.com/PerBothner/stderred) of stderrred: If DOMTERM is set, then it uses the DomTerm-specific escape sequences. This has two advantages:

- If the error message has ANSI escape sequences (like gcc does), then you get an ugly initially-red output line.
- You can do fancier styling with CSS, since the DomTerm escape sequence creates an element explicitly marked as error output, which is more semantically meaningful than "red".

Is it really a big risk?

The annual report has to describe in detail whether the company complied with the regulations in accordance with subparagraphs (A) and (B) of section 7(b)(1), and to the extent that the company did not list which regulations were violated and how many consumer's personal information was impacted.

7(b)(1)(A) requires the company "to establish and implement reasonable cyber security and privacy policies, practices, and procedures to protect personal information used, stored, or shared by the covered entity from improper access, disclosure, exposure, or use".

7(b)(1)(B) requires the company "to implement reasonable physical, technical, and organizational measures to ensure that technologies or products used, produced, sold, offered, or leased by the covered entity that the covered entity knows or has reason to believe store, process, or otherwise interact with personal information are built and function consistently with reasonable data protection practices".

To be criminally liable the officer has to certify the report "knowing that the annual report accompanying the statement does not comport with all the requirements set forth in this section".

In other words, to be criminally liable the officer has to lie to the FTC.

The main risk it seems to me is that the officers might be given false information from underlings, leading the officers to believe the report is accurate when it is not. If the FTC discovers this, their initial suspicion will be that the officers were the ones that lied. If the officers keep good records of where they got the information they relied on when certifying the report, they should be OK, although it will certainly be something of a hassle.

This only applies at companies with $1 billion or more in annual revenue that deals with personal information on more then 1 million consumers or consumer devices, or that deals with personal information on more them 50 million consumers or devices.

I'd expect a CPO or CISO at such a place is paid well enough to handle this.

So? Skim milk tastes nothing like full fat milk, but still has a right to exist.

It's something sorta similar to milk that can be used in roughly the same applications - lighten coffee, moisten cereal, baking, sauces, fold into mashed potatoes, etc.

I prefer the taste of pretty much all nut milks to cows milk, personally.
Computationally it's not a problem, but other issues abound.

Good luck with changing the start working hours for most of the companies from an entire continent from around 8-9 in the morning to about 7 in the morning, so that people could have the chance of catching an hour of daylight in the winter by going home at around 3 or 4 in the afternoon. That's not going to happen anytime soon.

my webapp is cloud (old style webapp, not that much cloud if you ask me) but for the simple reason that I allow users to cooperate (couples, families). I'm going for the subscriptions model because I'd like my customers to be those who actually use the app and not some effing corporation leeching more profits from my users.

I did wonder though about the hyper-sensitive users who prefer running the app and data themselves. To be honest, the answer is to use a different, ideally open source, software like gnucash, ledger/hledger, or beancount (I used the first two myself). which all come with their own limitations.

Would there be a market for me to offer my rails/mongodb/... app as a docker container that you deploy wherever you like? I'd not even bother about DRM.
