Well, a year or two ago, at least T440s ThinkPads came by default with a Realtek wifi card, for which there were no good Linux drivers [1]. Lenovo had an option for intel wifi card at no extra cost, but you had to be clever enough to choose that option when ordering the laptop.

Ask HN: Authentication (Self or 3rd Party?)
Hey HN,

I have a new project that is a multi-tenant project and might one day use SSO, AD, Office365, etc.

So I'm wondering should I just code my own Authentication Service (microservice) within my infrastructure. Or should I deal with a 3rd Party IdP such as Auth0 or Stormpath?

Rest of my infrastructure will be microservices so a JSON Web Token will be the required token that gets passed in headers.

Its possible only because human labor is cheap. And that is because those people have nothing else to do. Population is high, resources are scanty. People will do whatever they can to make a living.

But in most urban metros, cost of human labor is only going up. Washing machines are all over the places, dryers which were absent even a few years back are showing up. Robot vacuum cleaners are replacing few-hours/day maids all the time.

This is even more so in high rising apartments. Maid culture and personal servant culture in India is ending with urban living.

A mechanical gear transmission is more efficient than a generator and motor. Can you make up that difference? For trains nobody has the ability to make the required parts of that size (this might be in part that you can't fit them in the space required - I think you could build the machine to make them if you wanted it)

It is only with the most recent emissions standards that the losses from non-optimal RPM is a significant factor and the generator/motor is better.
I've used it for a few small tools and love it. I started out just writing schemas for testing the format of JSON generated by tools or pulled from an API, but you can do so much more... like using it to generate documentation or even [create forms](https://github.com/joshfire/jsonform).
Business Continuity with SD-WAN
RHEL is not the same as Fedora and RHEL devs are not the same as Fedoras. From what i seen in the last few years, at least.

That they are employed by the same company, yes.
Perhaps a way to help understand this.

Power delivered by the battery is this equation:

P = I * V

So you can have (1 volt @ 100 amps), or (100 V @ 1 amp) and still get (100 watts). If both are the same, wouldn't the low voltage solution be safer, and more desirable?

Massaging the same equation a little bit, we can model our losses along the power lines. Substituting V = IR you get...

P = (I^2)R

It's difficult to make conductors less resistive without using expensive metals or unconventional techniques (like cryogenically cooled wires). So to cut our losses, we'll go with high voltage, low current.
At least nobody would get eaten by polar bears.

There's no reason to feel bad about not exercising. If you don't like it, just don't do it. Sure, it might somewhat increase your life expectancy, but hey, so can other things. There's no way I'm going to do it unless I'm getting 10+ years or some very tangible benefits that are otherwise unobtainable. There's absolutely nothing enjoyable about it for me. I feel much worse about missing my daily Dual N Back session than about never exercising [0] in my life. Just let it go.

> I can get a bus to downtown Pittsburgh a block away from my house, but I'll almost always drive

Pittsburgh's bus system is definitely not the most timely or reliable of bus systems I've used, but I have the opposite experience here: parking is a huge pain, drivers can be insane, and I'd much rather sit on the bus reading Hacker News on my phone (or whatever). Maybe not for the occasional Costco trip but definitely anywhere in the East End.

Granted, (i) I also have an unlimited bus pass via CMU (sunk costs work both ways!), and (ii) I'm close to several frequent routes (in Squirrel Hill). If I had to pay each time and buses were less frequent I'd probably be thinking like you are.

In any case, OP's two-hour number seems pretty off-putting. Agreed that time is an important consideration at that scale :-)

I'd buy that logic if it produced low defect rates and high uptime, but it doesn't. When we used SilverPop earlier this year it was down about 5% of the time and wrong 5% of the time, and even the basic way the interfaces we had to integrate with worked was a mess.

Indeed. The most succinct version of this school of thought that I have heard, which was a NYT Magazine cover story about ten years ago, is "Eat Food. Mostly Plants. Not Too Much."

The way those concepts are fleshed out in the story is pretty compelling: http://mobile.nytimes.com/2007/01/28/magazine/28nutritionism...
Sounds like Michael Pollan: eat food, not too much, mostly plants

It's just my opinion, but I think this architecture is only advantageous when you need to build something with a complex user-facing CMS. Think lots of forms and controls with real-time feedback, optimistic updating, drag and drop sorting, etc. Across many pages with many object schemas. If this is the case, you'll save time by setting up a flexible module system with predictable data flow. Users will spend less time waiting for pages to load and edits to save. If this is not what you're building, stick with traditional server-side templates and a little bit of JS on the front end. I certainly wouldn't use this stack on a corporate marketing site, for example.

IANAL, but given there is no statute of limitations on prosecuting most major felonies like murder. it seems that the legislators would just change the law after a felony was committed allowing for the prosecution of the crime. At least from my limited knowledge they have done that in the past to fix issues, so I am not sure how this would be any different.

I do think it is interesting how the legislating bodies allow this type of stuff to occur (and not fix it timely), but it seems more a procedural technicality then a way to get away with anything. In addition, I am sure a prosecutor would allege the crime originated outside the jurisdiction giving the place where the "thought" or "plan" occurred jurisdiction to prosecute. And in the end it would be heard by a jury in that jurisdiction and regardless of the truth they would get their conviction.

This is a great story to tell (as the book written from it likely does) but no one would likely get away with a major crime if they were caught just because it occurred in this area. Petty crimes, I bet would go unnoticed and never be brought to a hearing because of the quagmire, but not a major felony.
As a programmer, how can you not care? You stare at it all day.

That's like saying some art dealers don't care what paintings look like. They just sell the stuff.
I think the limiting factor for most people is motivation, not intelligence.

Reading books and doing tutorials will certainly help you, but you might get burned out quickly. Working on projects seems like a much better use of your time.

Eventually, you'll have to pick up some books and learn theory, but the main challenge is getting to that point where you'll find the theory useful.

The thing about tv, smartphones etc is that they are incredibly addictive and I'd prefer to avoid my kid being addicted to something before they are old enough to decide for themselves what they'd like to have as a vice. I struggle enough with media/info addiction and I hope to help my daughter be aware of it and avoid it when she's old enough.

For the last year we have been working in a lightweight log shipper product called Fluent Bit[0]. Originally made for Embedded Linux now is taking it place in common environments.

It's pretty similar to Fluentd in architecture, some features are:

- Event-Driven (async network I/O).

- Input / Output plugins.

- Data routing based on Tags.

- Optional SSL/TLS for networking operations when required.

Next major version 0.9 will come with buffering support (memory/file system). Ah, it's fully made in C.

My wife and I are working through the old Tom and Jerry cartoons with our toddler, and we are shocked to see how much blackface there is.

The population of people who qualify for taxpayer subsidized Medicaid cabs is significantly less than the US population.

Most cab companies in non-huge cities have three lines of business: Medicaid cab, Airport cab and drunk transportation.

Two of those markets are essentially captive markets (companies bid for exclusivity) and drunk people don't have discerning judgement. That's why Uber/Lyft is obliterating the industry.
If it's art, perhaps that's exactly the point the artist is trying to make. I think I tend to agree with critics of the article, because rather than explore that point, they use it as a chance to generate pageviews by an incredibly shallow moralizing of something that could be considered art.

Any transgressive or satirical piece of art could have this exact same critique leveled at it, but generally they don't because critics in other media have a more nuanced understand of the relationship between art and the artists intentions.
You're getting some downvotes, but it raises a question about the basic concept of utopia as it's been explored by many, many authors. All the ones I can think of achieve peace through homogenity and comformity, often with quite restrictive rules on how you can dress, where you can live, who you can live with, what you do for work, how you spend your leisure time… and these are legitimate attempts at exploring the qualities of potential utopias, not just setting the stage for "then it all fell down" narratives.

Perhaps the area Star Trek does better than most (if one goes with the premise that it's a utopia, and really quite contradictory to it) is how humane and permissive it is with those who break the rules or fail to match the ideal (utopias don't tend to survive this kind of behavioral diversity). It might be big government, but there's still quite a bit of freedom in individual lives despite the militarized hierarchy and silly outfits.

Ask HN: Please help me become a good Product Owner
Hello HN!

I am about to begin at a non-profit as what essentially is a "Product Owner" position (although using others terminologies to describe it). My job is to lead the creation of a new multi-purpose (share content, function as completely online recruitment tool and create conexions/community with different audiences) website.

I am not a developer and my experience is mostly at fundraising for non-profit and sales, marketing and customer development for tech startups.

I would appreciate your help pointing me to good resources and tools to become an efficient and effective Product Owner.

Some more context: Consider me a beginner at this role, although I have some experience leading teams, implementing projects, founded an angel-invested startup outsourcing development. At this job I will be outsourcing all coding and designing, as ordered by the non-profit director.

thanks a lot!

But that's 1.5 hours of snoozing, reading, working, drinking coffee, having breakfast, whatever else you like, vs 45 minutes having to concentrate on driving.

I used to love my two hourly (total) commute on a train because it was two hours of enforced relaxation time every day. You can return home each evening completely switched off from work.
I think your mistake is that your assuming because some atheists are loud they represent all of them. It's definitely off-putting but those people are in a minority just as religious fundamentalists are in a minority.
All of this equipment needs power so that could be another attack vector. For example, we already have powerline networking. In theory you could include something like that in a power supply, after all it does connect to the motherboard and expansion cards. Of course it would require collusion among many different companies but it may not be out of the realm of a nation state attack.
I am no expert on non-physics sciences, but recently I am starting to worry that the way we do science today depends on ideal experimental and theoretical conditions.[1] In physics we see 2 sigma events vanish all the time, just last week we have seen the disappearance of the di-photon excess at the LHC. That was an excess that two experiments did see independently to a significance better than p < 5%, with well controlled statistics and well understood experimental set up. Similar the Auger anisotropy [2] was on the cover of Science and did just vanish. Again an effect with p < 5%, using blinded data analysis. My understanding is, that this data analysis is quite a bit better than the standard in other fields, and it does not really work reliably in physics, a field that is to some extend defined by ideal experimental conditions. (The saving grace for physics is, that the Standard Model and General Relativity tie different experiments together. So an experiment in conflict with expectations is immediately in conflict with a lot of other experiments.)

To be clear what I am saying, I do not think that other sciences are a waste of time in general. But I think that their methods are too much inspired by physics. I think that we need a much more cautious approach to the scientific method and a lot more robust tools. In a way, it looks to me like building a car by taking inspiration from Formula 1, when the task at hand is crossing rivers and navigating rough terrain.

"Epidemiology--is it time to call it a day?"

As far as I know the International Journal of Epidemiology is not big media.

Rhetorical questions don't count as arguments.

Observational research is intrinsically very, very hard. Statisticians are working at making it more reliable (especially in the context of causal inference: https://www.hsph.harvard.edu/miguel-hernan/causal-inference-...), but there's only so much you can do with data that is full of noise and confounders.

It was to hard to get started (running 1km if you never ran is a demotivating experience) and most of it was boring (running, going to the gym, etc) or filled with culture I didn't like (football and the gyms is full of "bros", climbing and running is full of "hipsters")

I wanted my own pace, without people around I didn't pick myself and something easy to get started without much effort to keep it going.

So I started lifting weights at home in februrary. Bought a barbell, two dumbbells, 100kg of weights and a squat rack (later a power cage + 40kg extra weight).

Now I can train in my bedroom 3 times a week without talking to any people and I don't even have to leave my flat, so no excuse like "I don't wanna ride to the gym" or "I don't wanna go outside". Since I'm working remote from home, I even can do it in my break in the afternoon (if it isn't too hot) and shower at home.

Also, I stopped riding the underground and get everywhere by bike now so I get cardio 3-5 times a week.
Banking and the credit industry are a good example of eventually consistent systems.
