It's a place you can go to talk with your friends and maybe make a few new ones, without constantly having things that show up that try to piss you off.

And as it grows maybe it starts to be a place where you have to go to find some of your friends. I mean, who the hell wants to be on Facebook any more? How many people still go there because that's where they can keep up with certain circles?

It's also a place you can run for your friends, and kick out anyone who comes in trying to start trouble.

We've got chill. We've got quiet. We've got a place to talk semi-publically without EVERY ASSHOLE INCLUDING A ZILLION BOTS being there, and we've got an overall structure that maybe makes it more likely for people to want to keep things civil.
Sure, but the point is Facebook should be taking minimum steps to actively avoid descrimination. It currently is not. Perfect shouldn't be the enemy of the good and they can do better.

If you need medicine more than you need food, why is it bad that the money is going to medicine? How is it better to give someone medicine + [cost of food] than to give them [cost of medicine + code of food] and then let them buy medicine and food as needed? It's the same number of tax dollars in benefits and fewer in overhead. And more value to the recipient because they get to decide if it's worth $5000 to have a marginally effective surgery or use the money for something else, instead of having a bureaucracy decide they can't have it when they want it or they can have it but not the cash equivalent if they need something else more.
The Matebook X Pro indeed looks good.
If you're tech saavy it's a bit less important. Scamming average consumers is sad, but ThinkPads to me are IBM, not Lenovo, so they have different boxes in my mind. The hardware is good, linux runs nice on it. Case closed.
It's easy until you realize how global Facebook's audience is. What happens if California makes this type of advertising illegal for hotels and Sri Lanka makes it illegal for movie theaters? Now repeat for every possible advertising law.
No only person that is responsible is the person who placed the ad. Facebook didn't select the target market and write up the copy.
I wonder why they dont put the blocks / dirt into train wagons and drive them up hill. Then generate electricity through retroactive breaking as it descends. Maybe the efficiency isn't 85%... but it sounds cheaper and simpler to make.

Too esoteric when cpp/java was the norm. Nowadays pure functional programming is a thing on the main stream, it gives logic programming an narrower gap.

I found CSPA to be an interesting proposal. I'm currently studying CS and Biology and found that the comparison of the exam to the "SAT" of computer science is a bit of a misnomer. The SAT requires minimal prior knowledge to take (albeit if you want to score well, you end up needing to study for it through test prep books etc). I think perhaps it may be more likened to an MCAT equivalent (or any professional school exam equivalent) because of the need to know about certain subject fields.

Someone also brought up a point regarding the validity of testing for skills in web development if test takers won't end up in those fields anyway. However, when looking at similar exams (e.g. MCAT), you can make the argument that the majority of doctors won't use Organic Chemistry or won't need to know about the minutiae of Psychology & Sociology to be successful. The MCAT becomes a successful discriminator of good vs bad test takers because of the amount of work and critical thinking skills that is needed to cover the litany of subjects tested. Similarly, the CSPA could follow a similar pattern as the MCAT by testing a range of subjects as a means of measuring one's ability to learn a large sample of topics.

The only thing I can really think of that CSPA can improve upon is providing more preparatory materials. Additionally, it'd be useful to see how people end up performing on the exam and if there is an actual "Bell Curve" like distribution of scores that results.
The other person's reply to you was really this simple:

You are asserting a slippery-slope argument, but this is a situation where there are clear places this doesn't lead. It may be fuzzy instead of a clear line, but there's not actually a slippery slope necessarily. And you need to bear burden to show that there is a slippery slope.

https://en.wikipedia.org/wiki/Slippery_slope
>I think it is reasonable to say that everyone should agree that if there are rules they should be universally applied

What happens if the rules are bad rules? E.g. if it's illegal for Facebook to allow advertisements for marijuana dispensaries on a federal level? Clearly that's not something we'd want to see universally applied.
I'm not sure people understand the inevitable progression here.

Step 1: HUD files a complaint against Facebook for allowing ad targeting based on certain criteria.

Step 2: Facebook bans advertising targeting based on the criteria in the HUD complaint.

Step 3: Advertisers react by targeting based on demographic correlates of the categories from step #1.

Step 4: HUD notices that ads are still getting delivered more to one group than another.

GOTO STEP #1.

There's no clear point at which this process stops. Demographic correlates are numerous and strong. Are you going to ban all of them? That's tantamount to banning ad targeting generally!
While good fiction, this is pretty dumb. Did Sherlock count the number of tiles on the wall as well? What about the colour of the carpet or the number of cracks in the ceiling?

Knowing how many steps there are is useless information and wasteful to retain.
You are looking for the word "database" and use that with an api.
No issues with my 2018 15" MBP. Runs perfect, solid battery life, cool and quiet. No kernel panics or any other crashes in 3 weeks of owning it.

Edit: Should mention I have only restarted it two or three times in those 3 weeks so it has had plenty of time to crash
Please just use an off the shelf system even if you disable a large part of it like with phpBB.

It sounds simple to reimplement, but you don't consider all the inevitable extras like user management, formatting, drafts, image uploads, notifications, backup/restore, etc, etc.

Don't get stuck on an inferior solution because you didn't want 3MB of unused code on your disk.
I need some extremely solid textbook on *saturated fat/fatty acids because I've read a few medical books (randomly picked) and ended with contradictory reasonings and conclusion.

Basically, some say that having single bond chains leads to less viscous molecules => less deposits. But some say that is double bonds which leads to less deposits.

But Apple hardware have no touch screens. I’m not saying it’s not an issue that Linux has poor touch support- I’m just questioning the validity of the concern; if you’d already decided to get a MacBook then you’ve made your peace with not having touch. Right?
Thanks for sharing such interesting papers!

May I ask what makes you think that the first paper has Deepmind's definition of intelligence? Was it said so by Deepmind at some point?
The tooling used by NixOS is custom to NixOS. You can check out the test directory for many more examples.

I'll be writing more soon about how these tests work and how neat they are. They really help NixOS quickly release really high quality updates!
Did you experience the sound issues?
Ok but the whole premise was that hydroelectric storage is infeasible in most places.
So what about your argument means they shouldn't handle the explicit descrimination cases on their platform better? Just because there might be a fuzzy case in they future why shouldn't they handle the clear cases now?

FYI these are the specific points they are going after:

-display housing ads either only to men or women;

-not show ads to Facebook users interested in an "assistance dog," "mobility scooter," "accessibility" or "deaf culture";

-not show ads to users whom Facebook categorizes as interested in "child care" or "parenting," or show ads only to users with children above a specified age;

-to display/not display ads to users whom Facebook categorizes as interested in a particular place of worship, religion or tenet, such as the "Christian Church," "Sikhism," "Hinduism," or the "Bible."

-not show ads to users whom Facebook categorizes as interested in "Latin America," "Canada," "Southeast Asia," "China," "Honduras," or "Somalia."

-draw a red line around zip codes and then not display ads to Facebook users who live in specific zip codes.

Pretty damn clear: gender, race, disability and religion.
"there are people I disagree with also using this space"

Claiming that is what people mean when they claim something is toxic is just as lazy, if not more so. And you’re basically saying that it’s on minority and underrepresented groups to be the one to engage, rather than those that are antagonizing them.

Alex Jones is an even more egregious case because he’s gotten in trouble not just because he “said things people disagree with”, but because he sent a harassment mob against the parents of children murdered at Sandy Hook, claiming it was a “false flag operation.” Several of them now are not able to visit the graves of their children, the harassment is that bad.

I’m sorry, but I just do not see this as anywhere near the “slippery slope” you’re complaining it is.
Ah I see now - yes you are right that would be an option since both fs an fs-extra provide sync functions.

Depending upon the number of files, the async approach will be faster (to be benchmarked) but you are correct that for 100 files or less on a modern computer at least there is probably no perceptible difference.

For me personally, I'm just so used to writing it this way, I didn't even think that it could complicate the tutorial - thanks for pointing it out!
Depends on the app. I run some things in the browser but if there is a native app for something, it's always more responsive and faster to use.

Pumped-hydro needs few high-powered turbine-pumps, of 100 - 400 MW capacity.

Solid material gravity storage requires vastly more low-capacity motors, of under 1 MW each, as you note.

Raw efficiency isn't everything.
When evaluating the warnings from naysayers you have to keep in mind that CS is quite an outlier as far as backup career prospects go. I made it all the way to CS postdoc and every step of the way I had to keep swatting away industry recruiters waving wads of cash at me. I finally made the leap for other reasons but it was effortless. I think this is absolutely not how it works in other disciplines.

One exception I can think of is what I call "closet programmers," which are folks that work in various areas which rely on software such as experimental physics, astronomy, molecular biology. and end up mostly doing programming because they love it. We have a bunch of engineers like that and they are all excellent :-)
I think it's the same people who call the ground floor the first floor. Coincidentally, I often have an off-by-one error in elevators.
A bold test. I like it!
Great feedback! We do have a distribution of scores for our latest exam session here: https://medium.com/@cspa_exam/july-2018-cspa-results-509ace9...
Their topics page https://cspa.io/topics also has numerous duplicate "example" links. Some of them are barely related to the sub-topic line item and some not at all (perhaps a typo? copy-pasto?).

I provided feedback that included this issue, I believe around when it was first a "Show HN" post, but the page was never updated.

That would certainly give me pause as to the accuracy of a technical (or detail-orientation) assessment.
I asked above but since you seem to be knowledgeable, I'm looking for some super solid textbooks on fats/fatty acids. Because as you say, you can read contradictory statements in different books.
I completely and utterly disagree with your “work out fine” sentiment. It is embarrassing that something set up like Mastodon was from the beginning did not plan for people to move between instances from the start.

I don't count them. But from long experience I know the most staircase have an odd number of stairs.

My first step is "short" and whenever possible all following "long". That usually works.

But to the current day I don't know whether there is a real reason to this observation. Maybe it's pure coincidence. Or maybe something typical to may country. Or after all it has indeed some real (maybe even wired) reason.

This is superb. Copyright trolling is a thing that among other technological trolling holds digital advancement back and brings some hope and justice to the system.
> It seems that as long as the housing and the ad content itself weren’t discriminatory, the law would seem to be upheld.

That's not the issue. The issue is the application of demographics filters. While most publications have a self-selecting audience, the publications themselves do not apply those kind of filters, especially with regard to showing advertising content to a subset of readers.
I’ve had similar thoughts and assume aliens would use something like lasers to have point to point communication rather than broadcast RF.

Of course for us we’d never detect those point to point transmissions unless we were incredibly lucky to be along the vector between two aliens communicating.
Yes, your examples are potentially unlawful. See HUD's guidelines here: https://www.hud.gov/sites/documents/DOC_7781.PDF

> § 109.25 Selective use of advertising media or content.

> (a) Selective geographic advertisements. Such selective use may involve the strategic placement of billboards; brochure advertisements distributed within a limited geographic area by hand or in the mail; advertising in particular geographic coverage editions of major metropolitan newspapers or in newspapers of limited circulation which are mainly advertising vehicles for reaching a particular segment of the community; or displays or announcements available only in selected sales offices.

If this sounds burdensome, it's supposed to be, changing society and correcting centuries of inequality and discrimination requires significant active effort.

Also remember that intent and reasonable expectations matter. You as an individual with limited means and no legal advice would be held to a different standard than Facebook, a corporation with many orders of magnitude more responsibility.

Finally, remember that law is not code. The Fair Housing Act is a tool to be used judiciously by humans to correct wrongs, not a precise standard that can be applied in the same way to every situation. It's not possible to write a law that anticipates every possible scenario, that's why we write relatively vague laws and involve humans at every step of the process.
Overnight Brain Stimulation Improves Memory
The X1 is nice but the T480 is only a little bigger, handles heat a lot better, and has (mine does, at least) about 16 hours of battery life under Fedora.

It's hard to really recommend the X1 (or T480s) as a developer machine, IMO.
I was about to comment to state that there is no advantage because both gravitational waves and electromagnetic radiation travel at the same speed: "c".

But then it struck me, maybe there will be one advantage, EM can be absorbed, blocked and warped while gravitational waves are not affected by anything, thus guaranteed to deliver the message(?)
While not legally 'censorship' we should develop a culture where such arbitrary deletions are heavily frowned upon.
Relative to kinetic/gravity storage, yes.

Relative to combustibles such as hydrocarbons, ammonia, or hydrogen, not so much.

(It's possible to synthesize carbon-neutral hydrocarbons, though with high round-trip losses, and not yet proved at scale.)
This is absolutely fascinating.

Interestingly, the cement industry produces ~5% of global c02 emissions [0]. (Cement is an important binding element in concrete [1].)

As this technology is presumably most useful for storing surplus energy from unpredictable renewable sources (e.g. wind, solar) I wonder if there is a conflict of interest? I'd love to know more about the carbon economics involved, perhaps they could use reclaimed (i.e. recycled) cement.

I visually count backwards in sets of four, and take an initial step of 1-4 so that I can subsequently take only 4's to the next landing. The momentum seems to make this climb more efficient.
Im surprised no one had mentioned the CO2 cost of producing concrete.
he reminded me that a nerd’s goal in climbing the steps is to establish the number of steps at the end of the flight.

I thought I was the only one who did this. I'll definitely be trying this method next time I find a novel flight of stairs.
Can relate. Bought a brand new notebook but am still scribbling notes on scraps of paper instead because I don't want to sully the pristine pages.

Something about the unlimited potential of an empty notebook - it could be the place for my magnum opus or my record of important insights which I would look back on for years to come. Don't want to mess it up with some random scribblings. And so it sits, pristine and unused, challenging me to create something worthy of it.
It’s always good to have more analysis and disagreement. But I’m not going to take the word of a few critics—who have never examined the victims—as disproving the thorough work of the excellent doctors at UPenn—who did. The next step would be to wait for those doctors to respond to the criticisms of their methodology and take it from there. It looks like they are in the process of doing that, so I’m looking forward to it.

Users should get the final say always. This was normal behavior before windows 8. Now windows users are guests in their operating system, and the attitude can be seen in other software as well, not only from Microsoft.

Firefox is an awesome browser and is the most pro choice browser on the market, with options for privacy plugins, search engines, cookie choices, tracking protection, etc.
Yes, really it does seem that way. Some more examples:

Tuberculosis in the 50s was still being blamed on psychology.[1]

Ulcers. Epilepsy. Myasthenia Gravis. Hypertension.

Autism was blamed on the mother’s personality!

Celiac disease. Schizophrenia. Cardiac diseases. Colitis.

Oh this is a doozy. Remember AIDS?

"It is argued that (a) AIDS is a typical example of epidemic hysteria, (b) the epidemic has at its core an unconscious group delusion that can be called the group fantasy of scapegoating" [2]

Turns out when people say they’re sick and something is wrong, there is almost always a cause even if we don’t know what. The body is complex. We still have a hell of a lot to learn. And doctors are being really lazy and damaging to patients when to dismiss a difficult to explain illness as psycho-genic/social/logical.

Your example of fan death is a superstition, which is not the same thing as an illness diagnosed as “psychogenic” by a doctor.

Not the OP, but I had a hackintosh awhile back, and it (obviously) wasn’t as easy as a Ubuntu install, but it wasn’t a complete pain in the ass either. After it was installed, most everything worked as good as it does on my macbook. The only annoying thing I encountered were OS updates, because installing them normally would more than likely break the install.

The OSX86 Project[1] is pretty much all you’ll need for instructions for getting a hackintosh setup running. And if you’re interested in building one from scratch, the OSX86 Project lists compatible hardware so you can know what you’re buying will work.

If you don’t mind having to do a bit of reading and tinkering to get it working, it’s a solid way to be able to use OS X on non-Apple hardware. But, if you’d rather have something you can just install and forget, you’re better off just installing your favorite Linux distro, or buying a Mac.

100% correct. I think we are both very lucky in that we are able to do fun science and chase our intellectual interests with a realistic and still fun safety net.

Also those closet programmers are always really fun to talk to since their problems and culture are breath of fresh air.
The tests are written in Perl and are invoked by Nix's build tools. You can skim the API at https://nixos.org/nixos/manual/#sec-nixos-tests

In this case, the test makes use of both xdotool and Nix's own testing library.
Our legal system will not hold Facebook liable for a case like that.

Should?? Like how things ought to be with the world? Facebook shouldn't even know who prefers organic food. There should be nothing tying that preference to any other aspect of people's lives. Facebook should be more like Reddit where people can have whatever accounts they want and can interact on organic food topics without identifying themselves or tying that preference to other interests. Or maybe Facebook should have an explicit opt-in for users to choose what they're okay with being used for ads… … should? everyone should use an adblocker and block Facebook's ads. Also, Facebook should offer a service where you can choose to portray yourself as whatever mix of qualities you want to set for each time you search for something. So anyone should be able to see what the algorithm delivers for a set of characteristics they can adjust at will…

Also, I should stop procrastinating on HN
