>Imagine dark matter had been proposed in 1900: the deviations in Mercury's orbit (from Newton's model of gravity) could have been attributed to dark matter. No need for general relativity...

You should have a look [here](https://io9.gizmodo.com/the-200-year-old-mystery-of-mercurys...): TLDR: they looked for a 'Vulcain' planet which could cause Mercury's precession, but they didn't found one.

And for the dark matter, you're right that both aspects should be researched, and both ARE researched but dark matter currently fits better the experimental data as already said.
Of course until we know exactly what is dark matter, there will be room for other theories..

I'm interested in this, partly because I'd like to have an easy way to get richer web pages: Instead of reading "This was X dollars in year Y, the equivalent of Z dollars in <years ago>" I'd like the author to be able to just put in the facts: Something like $[X|Y], with Z being generated automatically by the web page, which means it'd always be current and you could get a ton more context, like currency conversion.

The big issue with the small displacement turbo-charged engines is that, at normal autobahn speed, the engine is almost always on boost and therefore burning a lot of fuel to:

1. Reduce intake temperatures/prevent pre-ignition

2. Produce enough power to sustain a constant speed of 120KPH or whatever

This means that they are far less efficient than they should be, and in some cases get more or less the same efficiency as larger displacement high capacity engines.
Whenever I see someone talk about something like that being "free" my initial reaction is also that they must be trolling. Sadly, it usually turns out they are not.
There’s plenty of evidence to suggest some portion of likelihood of being gay is controlled by parental hormones. E.g. the probability of being gay is observably higher in men born after an older brother.

Perl 5 post 5.12 is nice but people like rurban an mlehmann claim p5p are screwing it up and breaking backwords compatibility for no good reason. These two individuals are quite knowledgeable programmers, so I'm inclined to agree with them. Both have created their own fork of Perl 5.

Perl 6 is quite nice as a language but the implementation is slow and it has too litlle lib support. Also not great for scripting because of the VM penalty.
If you want a broad overview of how RDBMS work under the hood, "Designing Data Intensive Applications", would be a good conceptual start.

This could be followed by database internals books like "Expert Oracle Database Architecture" and "Pro SQL Server Internals", irrespective of whether you use these databases or not, you will learn a ton of stuff about database internals and system design.

If you are interested in database schema design etc, then look up "The Database Model Resource Book" Volumes 1,2,3.
None of the above are quick reads but they are solid foundations for becoming a well rounded DBMS professional.

Pretty much all CPUs with MMUs since MULTICS inherently support fork(). So for NT it's a question of prohibiting the behavior. Microsoft's research department even writes papers about how they disagree with fork(). I was truly impressed by the work they did implementing Linux ABI in the NT executive for WSL 1.0. Big change in policy. It's going to be sad to watch it go, but might be for the best. A really well-written ghetto for Linux code is still a ghetto.

If someone has a desire for or the capability to enjoy sex with both males and females, they are neither heterosexual, nor homosexual. They also do not change their sexuality. They are simply bisexual. The fluidity here lies in whether someone has at some point in time more interest in women or men and which desire they act upon. If one's interest in one of the sexes goes to zero, then one could argue that persons sexuality did indeed change from bisexual to hetero- or homo-sexual.

Bisexuals indeed have the unique opportunity to "decide" which side of their sexuality they pursue, because they enjoy both. That's what makes them different from "true" heterosexuals and homosexuals who can not enjoy both. (Though one could argue a homosexual forcing himself to have sex with a woman and make a family is not truly homosexual and we do know that's possible and happened quite often. I will leave that to the philosophers.)

Please keep in mind I am not even arguing for the "born this way" view. I have a "It does not matter" stance. I welcome ideology free research to clear it up though, but don't we already know the results? Both genes and environment play a role...
University doesn't generally teach DB with any real vigor. I personally do not have a CS degree but I have been in tech for a long time and I have a lot of data side experience. When I hire new grads they commonly lack basic common DB skills even when coming out of very high end CS programs. There are exceptions of course, but as a general rule this isn't what a CS degree gets you. I find people that come out of bootcamps (DBA and developer) know more relevant DB skills than do new grads.

That said. Postgres, MySQL or any relational database is a good place to start for forum software. There are valid arguments to be made why a document db might be superior in some cases but honestly if I was writing a forum I'd probably look towards Postgres and if search was going to be key, I'd also likely have ElasticSearch as part of the solution. I would suggest whatever DB you chose don't chose DynamoDB for your first real attempt. DynamoDB gives experienced data engineers headaches. It isn't that Dynamo is bad, but there are very distinct tradeoffs you need to make and weigh to setup it up for your use cases. For the record I'd also avoid Cassandra for the same reason. Something like Postgres or MySQL is more forgiving when you are learning IMO. Other options could be MongoDB (people like to hate on it for issues long resolved), SimpleDB, AWS DocumentDB etc. Amazon's document DB is Mongo Compatible but uses their backend and is very easy to work with.

Just some ideas. Also you could look at some of the open source forum software out there. Might help you get ideas.
Or perhaps even the 10$ or so Chinese Tevise automatics.
That is a very tortured misunderstanding of the second amendment. I would strongly suggest reading Scalia’s decision in Heller - he thoroughly debunks this argument, and it’s now settled law, so it would be worthwhile to understand how it really is vice how revisionist historians want it to be.

Probably. They make use of a farmers market heavily too & are probably more eco friendly on amount of packaging. So not really criticizing just find it crazy opening the fridge when I visit (once a year :( ) and am just stunned by how much food they keep for 2 people. At one point they had 2 full sized fridges.
>Lifetime of 2 to 3 years, daily use ...

It seems to me like a short expected lifespan, following is anecdata.

The glasses I am wearing (the frame) are/is 36 or 37 years old.

Every several years I had new lenses fitted to them, mostly because my eyesight slightly changed, right now they sport a brand new set of lenses because I broke one lens and since I use the photochromatic kind I couldn't have only the broken one replaced (the colour and capability to darken changes a bit over the years), but I don't think I replaced the lenses more than 4 times in these almost 40 years.

Then I have another four pairs, one spare in the car glove compartment, one spare always in my suitcase, one for the motorbyke (sun lenses + short stems to fit under the helmet) and one as spare-spare.

And I believe that (besides changing some lenses as well) none of these latter frames are more recent than 15 or possibly 20 years.
Ok but you’re kind of just throwing numbers into the mix here to justify your position. What if the manager makes $12.50 an hour? Or $10?

For modeling individual galaxies, that's more or less correct. (Of course, the same applied to things like MOND: "hey, if Newtonian acceleration is tweaked with this interpolation function and that free parameter, it will explain the observation".)

In a large-scale, statistical sense, the answer is: initial quantum fluctuations (as seen in the Cosmic Background Radiation) + gravitational collapse and fragmentation in an expanding universe. Simulations done under these assumptions have done an increasingly good job of describing the general distribution of dark matter, and the typical statistical distribution within galaxies.

This is why it's good to do independent fits of dark matter distributions to galaxies: it provides something you test the simulations against. After all, if the individual-galaxy fits say dark matter generally has distribution X, but the simulation say that gravitational collapse and mixing should almost always produce something different, then you know you've got a problem.

"If it interacts with visible matter gravitationally then why doesn't it take on the same distribution?"
Because visible matter interacts with itself via radiation and hydrodynamics (e.g., gas pressure). So it gets pushed around in ways the dark matter can't. These forces can be much stronger than gravity in some circumstances (gravity, after all, is the weakest fundamental force), so the gas atoms, ions, electrons, etc. experience forces the dark-matter particles do not.
You can do statistical analysis if certain users get checked unusually often (I.e. generate tickets only when checked). After some time you can force those users into online only mode.

It's a way to steal from the local community given that public transports are financed mostly by tax money and by tickets (a tax based on your usage of the infrastructure). They present it as if it was a political action. That's rather ironic IMHO.

Free public transports just mean that you pay it through another way, and most likely mean that you remove the "use tax", thus increasing the contribution from people who don't actually use public transports.
Hi,

I've noticed that often people sharing images with details in subject either:

— describe image (say in comments) shortly, because it's not convenient, or

— put description in comment with need to tell where to watch (e.g. top right corner), far from image, or

— use some tool (Photoshop?) to embed description into image.

So I develop and recently released platform where users can describe details of images and share link to it — DESCRiBE (https://www.descr.be)

I've added sample posts to explore possible use cases:

— Lunar features (craters and seas) — https://www.descr.be/posts/2

— Manhattan skyline — https://www.descr.be/posts/3

— University of Oxford aerial — https://www.descr.be/posts/25

— Few reef fishes — https://www.descr.be/posts/4

— Stuff for filmmaking — https://www.descr.be/posts/6

— Notebook stickers — https://www.descr.be/posts/1

I invite you to check it, tell what you think and remember to use, when you’ll need to annotate something — describe it and share a link.

Hope it will be useful and make Internet a better place.

Near future plans:

+ allow links,

– stick annotations while scrolling tall images,

– adopt for small screens,

– add categories.
I’m sympathetic to the idea that public transit should have means tested fares, but outright free is a bad idea. It costs something to provide, quite a bit actually, and has limited capacity so there needs to be some mechanism to gate access. Price, which forces users to consider trade-offs, is the most straightforward way to do so.

>He doesn't think much of the artists creating comics either. Maybe he thinks only artists that display their work in galleries are "real" artists. Personally I think artists like Bill Watterson and Randall Munroe have done more to push the cultural zeitgeist than any artist in the last 30 years.

Get on a bus in the middle of the day and count the number of people paying.

I.e those not on benefits, over the age of 18, under the age of 60 etc.

Now count how long the bus idles while people line up so the driver can validate their ticket / check they tapped in on their Oyster card.

Now add in all of the infrastructure and staff required to collect fees and account for them.

Then add in all of the external costs of charging for public transport (more cars, less productivity)

The argument for charging isn’t that strong.

> Why would they be?

Because their position is naive and lacks any serious economic or political justification. Even assuming that their beliefs are sincerely held, this would not be the correct course of action to go about inciting change.
I could be misunderstanding this sentence, but from the linked page:

> Importantly, [entropic gravity] also explains (without invoking the existence of dark matter and its accompanying math featuring new free parameters that are tweaked to obtain the desired outcome) why galactic rotation curves differ from the profile expected with visible matter.

I get that entropic gravity doesn't use free parameters.

Also, I don't think that free parameters are necessarily so damning. I happen to have more hammocks than usual in my house. Any theory about how hammocks are distributed will either fail to explain the concentration, or will predict that hammocks are more likely to be found near people who like them, and then will subsequently fail to provide a way to derive the location or distribution of those people. That failure would be a free parameter. It's not necessarily an indicator of wishful thinking. It could just be that the theory knows its limits.
Nice story! A good read to start off Monday morning.

>The kind of art he supports already gets plenty of funding. No one seriously expects MOMA or the Met Opera to go bust any time soon.

Isn't that part of the author's point? In that the MOMA or Met Opera's funding are quite distinct from what the masses fund (and from what the masses consume). Not to mention that museums shouldn't be where the culture is consumed, that's where already established culture goes to die.
Where do you see the problematic interpolation?
The plain language of it clearly enshrines an individual right. No one seriously believed otherwise until the Jim crow era, when it became popular to write laws that were understood to apply to only one group of people and specifically sought into disarm them so they would be unable to defend themselves from the KKK.
However, for a long time the main competing theory for WIMPs was MACHOs (yeah, really), basically "familiar" dim, compact objects such as brown dwarfs and black holes, scattered around in the galactic halo. However, gravitational microlensing surveys have found that the observed density of MACHOs is far too low to make up a significant fraction of dark matter.

It does work in the West you just need to enforce the rules. There are Western countries that do this well and there are ones that fail at enforcing these rules.
I think we are more aware of depression than we ever have been but it has been going on for much longer than millennials or gen z. The _value_ that each individual seeks in life cannot be found in this modern world. I think that's due to both fewer human connections and a lack of purpose from some passionate skill or trade - more value placed on high social status determined by virtual numbers, your _perceived_ life, and consumerism.

So the goal is to say "look, your security is stupid, we will all have free rides until you fix it"? That's most likely to result in more money being spent by the public transport company to counter the bad PR and fix the issue.

You write we should reduce:
international shipping, consumerism, and non-essential air travel

Sure you can but it will be heavily inconvenient (at least for many in the west).
But do you know what reduces the carbon footprint by about 75% in a country like Germany?
1.) Electric cars/trains
2.) Electricity from renewables
3.) Heating using electrical power from renewables (heat pumps)

Of the last 25%, there are 20% from industrial production and in the last 5% you could include air travel (2%) among other things.

Heating and driving and getting power from renewables makes your lifestyle about 0% different from what it is now. Buying goods that last longer even means giving life a touch of luxury. A better, more luxurious lifestyle that produces about 75% less carbon dioxide.
Impossible? In a growing number of countries, this will be possible soon.
Of course, not flying, not consuming gives you that "holy" feeling of "having done something". But done right, a sustainable lifestyle makes the life we have now even better. It takes a bit of political willpower, of course.

"My other issue is that in discussions of rotation curves, I keep seeing reference to Kepler, which simply shouldn't apply. Where can I see the math behind the "expected" curve"

"Keplerian" in this context is an approximate term. It refers to the fact that most of a galaxy's visible mass is centrally concentrated, and so as you get further and further away, with virtually all of the mass inside whatever distance you're at, the rotation curve should converge on a true Keplerian one, because the difference between the effect of the true mass distribution and one where all the galaxy's (visible) mass is concentrated in a point at the center gets smaller and smaller.

Actual published fits to galaxy rotation curves always use the measured visible-mass distribution for a given galaxy to compute the non-dark-matter curve. No one working in this field is confused about this.
