Eggs, chicken, pork, even flour can be contaminated - Chipotle (a popular US fast-ish food chain) had woes upon woes until they finally gave it and started pasteurizing their flour. Dairy and meat are more susceptible of course, but even dry ingredients can come with contamination problems.

Vinegar is a decent cleaner. I use it quite a bit myself, but it's not the best choice to clean up after raw meats and some other more aggressive bacteria. You may have a good immune system, and not run into any problems - good for you, I'm glad - but that is not going to be the case for any large group of people.

> Lactic acid bacteria and yeasts do an excellent job of preservation

Preservation is not sanitation. Yeast will feed off of many things and grow, but it won't typically attack germs or viruses. Those germs will however gladly feed off of the same food you're giving the yeast. This is why aggressively sanitizing any fermenting vessel is so important - you're creating the ideal environments for bacteria to grow and you want to make sure it's only your selected bacteria that are growing.

> Keep in mind this is how society was for a long time.

That is a myth and falsehood. The work week for the average person going back thousands of years was 60+ hours. There was no vacation or sick leave. Sure, if you had a small cottage industry you might be able to ask a family member to do extra work for a day so you can rest, but for most of history children were pressed into labor at ages 8 - 10.

> People who abandon everything to live in a commune take personal interest in caring for one another

Then they should practice good sanitation and cleanliness. I'm not saying they shouldn't live in a commune, or that they're bad people - I'm saying they are not correctly practicing what we've learned in 10,000+ years of handling food stuffs for a community. If you care for your friend/neighbor/fellow commune-peer, then take a moment to wear gloves and a hair net so you don't get them sick.

Which European country doesn't have debit cards?
Britain had its own fascist party, the British Union of Fascists, formed and led by Oswald Mosley. On 6 October 1936 (just two days after his blackshirts came off rather the worse in the 'Battle of Cable Street'), he married Unity's sister Diana, at a private ceremony in Goebbels' home. Hitler attended both this and an extravagant follow-up celebration hosted by Göring and intended to upstage Goebbels. During these events, it became clear to everyone present, and especially Mosley, that his bride was infatuated with Hitler, something that Mosley was not, of course, particularly thrilled about.

At least three of Unity's and Diana's sisters (Jessica, Nancy and Deborah) leaned left to a greater or lesser extent.

> I find that it makes conversations less aggressive

This is a really interesting perspective on it that I hadn't considered. I have long been annoyed by the lack of comment notifications but now that you put it that way I think you're right. This actually may be a feature of HN rather than a bug. Thanks for sharing that point.
They did measure them, so I'm not sure what you're getting at.
Nuclear still costs far to much vs Wind and Solar.

If all greenhouse gases came from electricity generation then doing the France model might work, but it's much better to cheaply go 95+% renewable and use the savings to cut down on transportation and home heating etc.

PS: Grid scale solar is rapidly hitting 2 cents per kWh in sunny places. Nothing else is anywhere near competing with that.
And also the company that caused quite a stir when they partnered with Firefox to carry out a study, which included collecting and sending browser data to Cliqz servers.
Also, 'no pain no gain' only really applies once you've blown out all the beginner cobwebs and have a solid base of athleticism. Until you're comfortable cranking out a 5-k without stopping and without feeling spent (or whatever the rough equivalent in your sport is), you're going to make way more progress by taking it easy but just getting out there and doing it regularly. Basically, if going hard doesn't feel rewarding when you're first starting out, you're probably right.
Be interested to see what proportion of those who do this can't afford it or can't get it.

Seattle has GPS on most busses that integrates into apps like Transit. Transit is also crowdsourced if people leave it running when they're on the bus. Some bus stops also have screen timetables that update live information regarding arrival time.

I know I have to leave my condo when Transit says 3 minutes and it has the "this bus is reporting" logo.
Not really. It's about irrational humans and magical thinking.
Back in university, I rewarded myself with one attempt at 3-ball juggling after 30 minutes of studying. So, my hackathons were throwathons :-) Worked great, and I learned to juggle within a week.

Somewhere else I read that someone did push-ups, squats or planks during breaks. That would be a great tip for me nowadays. Pushathons?
Oh wow, this site was an absolute godsend in college. I was stuck in a DiffEq class with an abysmal professor and barely hanging on. I found this a few weeks in, stopped bothering with useless lectures, and went from low-60s to high-80s over the rest of the semester.

"a language that was super awkward for the first 6 months or so, but turned out to be a keeper"

I wonder, do you consider the language's awkwardness somehow related to its quality? Do you see it as a prerequisite to avoiding language shortcomings?
But your estimate isn't very meaningful if you only have enough samples such that the N v (N-1) normalization matters, the variances on the estimator will be too large. The 1/N normalization comes from the MLE BTW, I'm sure most know this already. As an aside, to see the power of a biased estimator look at the James-Stein Estimator [1].

I'd like to write a more algebraic understanding of differential equation, e, derivative and integrals. Something like Maxwell equations (pardon the pompous aspect) but for all things differentials. There's a webpage about differentiation that starts that (and is the inspiration behind my quest).

If you're going to argue that implementation difficulties make DNSSEC too much trouble I can respect the argument. To say that it doesn't solve a problem worth solving is strange.
As a bus rider who uses apps to track expected arrival times (not to be confused with scheduled arrival times), here are some thoughts:

Timing when you leave the house/office to catch the bus matters a lot more when weather is miserable and/or when buses arrive infrequently than when they arrive frequently and the weather is nice.

The bus I take most often is scheduled to run every 3 minutes on average during my morning commute. That means that even with severe bunching I rarely have to wait more than 10 minutes. Unless it's under 10F outside or is raining buckets, I just leave the house when I'm ready to leave the house, and use the bus predictions mostly as a way to manage frustration levels.

It takes me about 90 seconds to get from home to the bus stop if I make the light, BUT there's a really long traffic light in between. If the bus is listed as 4 minutes away, I have a 50% chance of catching it (depending on whether it makes the previous light). Less than that and there's a 90% chance I'll miss it.

Also, the arrival predictions seem to be based on distance and stop count rather than typical local traffic conditions. It also doesn't take into account times when the bus is empty and skips most stops or is full and not only stops everywhere but boarding and debarking take forever. Which means that while it's eerily accurate for certain stops and times of day, at others I can count on the bus to arrive in half the time predicted and at yet others in twice the time. Unless there's a crash or construction along the route, in which case all bets are off.

During my evening commute, the buses are scheduled much further apart (and are a much longer walk from the office). A 10 or 15 min scheduled headway means leaving whenever you're ready works well if the buses are reasonably spaced (regardless of whether they're actually on schedule). But bunching sometimes causes a 20-25 minute wait (and occasionally more). What I find the bus arrival predictions best for is to be informed on those occasions when the bus is half an hour away and your best bet is to say "screw it" and walk or take a cab.

On another route I frequent, I get on at the first stop on the line. The next bus is always parked around the corner (unless it's super late completing the incoming leg of the route). The app I use lists it as due in 1 or 0 minutes. The actual arrival time will in fact be the scheduled time.

What it comes down to is mostly about knowing your route and adjusting your perception of the predictions to take that into account.
Zenefits’ Parker Conrad Returns with Rippling to Kill HR and IT Busywork
Given that historically it's taken decades to build new plants from scratch this doesn't look like it will be nearly in time to make an impact.
Click your username-> comments, and you get above list of your comments, ordered by time. I think it’s perfect. I don’t like having little notification icons everywhere.
@galeaspablo, sorry I should have been more clear. What I meant is basically the comment above. I highly recommend "Introduction to the Theory of Computation" by Sipser.

As I mentioned in my original comment, I barley passed Calculus. CS Theory is still math, but just... without numbers. The class felt more like solving puzzles, if anything. Writing proofs and doing homework was fun. I regret renting the book, I'm thinking of buying it just to work on the exercises within.
Have a look into flatpak too, otherwise in the not-so-distant future the users could have a problem.

For Fedora, they are planning switching to Silverblue around Fedora 30 (atomic system, rpms still supported, but jumping around the hoops).
Walking to the grocery store means you live within walking distance. That means zoning codes that allow a grocery store in your neighborhood. Most do not allow that.
I haven't got much experience with EOS. My feeling is that they are a bit newer to the scene than stellar in terms of adoption/traction. They only launched this summer and stellar has been gaining traction since late last year so they are a bit ahead on that front. Regardless of what you pick, you are taking a leap of faith in long term viability/stability of what you pick.

We went for stellar because we saw some traction there, kind of liked the notion of being in an ecosystem with a bit more serious players, and we liked what it did functionally.
Casual elitism is indeed what irks me here a bit as well.
Fundamentally, it's a consumer problem. Consumers don't want to pay more for using green power, or eat less meat, or use public transit instead of a car, buy an electric vehicle, or other things that restrict their comfort or degrade quality of life. Such restriction/degradation would be perceptible and short-term, while the climate threat is not perceptible and is long-term. Nobody really cares if the average temperature of the World ocean increases by 0.5 degree in 10 years. Most people see climate activism as fearmongering.
> My only wish is that emacs were written in an even better language than elisp (like Common Lisp)

There are a lot of bad things in CL too, unfortunately. I wonder if a Lisp will become really popular in the near future. Maybe Racket?
The Stellar smart contracts seem to function like versions of Bitcoin Script transaction types with more features. For me this seems like a more appropriate direction for transaction abilities in comparison to Ethereum's approach, which has more capability but also massive room for implementation error.
> The main reason my emacs is painfully slow is that most elisp code blocks.

Note that multithreading is now in Emacs master, and some core packages (e.g., Tramp, which used to block when opening a remote file) have already been updated to make use of it, so starting with the next major release things will be improving on this front.
You can get stuck, just idling along, if you don't decide at some point to try going beyond your perceived limit?
Implementing Async and Await with Generators
Never said to do away with the fundamentals. Will say that most symbolic differentiation and integration (which is a big chunk of the coursework) is not fundamental as much as it is fruitless busywork.

Even so, I spent a year of my time--and God knows how much of other people's money--grinding out the mathematical equivalent of crossword puzzles so I could get my job certificate--just like every other engineer.

Use that same time to apply the fundamentals to numerical methods, and you get to go in far more interesting directions--like symplectic integrals, or chaos theory.
In my experience, when certain users with sufficiently high karma flag a post or comment thread it is tantamount to "killing" it. Perhaps I'm mistaken in my perception of how flags work here. This is one of the more opaque aspects of how the site works.
I've got a new startup idea for you
But is omission lying by common industry sense?

You have batteries that decay and processors that scale; It's a feature of the processor that it scales down to protect the battery. If they were the only one in the industry that did it, or it didn't make longevity and safety sense, then maybe not mentioning "we prevent your device from randomly dying or catching on fire as much as the next device" is normal.

I don't see many devices using lipo that sell the feature "we prevent your device from catching on fire by killing it"; though they hopefully all have thermal shutoffs.

That's way down from when 10/10 music consumers were pirates, just trading songs with each other around campfires and town squares without deep thought paid to credit.

Seriously, exclusive rights to music creation and reproduction are a pretty new thing; I think humanity will survive this "recent" trend.
If you ask any STEM professor or TA that teaches undergrads, the reason so many students "wipe out" is because of a lack of preparation in fundamentals-- not just "calc 101", but even more basic than that, algebraic manipulation.

The material in a physics 101 course is just the barest minimum and it goes beautifully hand-in-hand with calculus 101.
Oh, I see. Yes, that is a very standard workflow. I also commonly address PR change requests in isolated commits as well, and then link back in the PR review page with something like “fixed in <commit hash>”, so that reviewers can see isolated commit changes fixing itemized requests, and also so that no review comments ever go without some explicit reply, either demonstrating the fix or explain why to not do it or table it for later.

I guess in this sense, these items don’t have much to do with whether the big conjunction of conditions necessary for TCR are satisfied or not.
As the economics continue along Swanson's law (the photovoltaic solar panel equivalent to Moore's law of ever decreasing costs) I expect the biggest obstacle to large scale transition to a distributed grid of majority local generation resources will be regulatory hurdles by legacy utility industry to protect their business model. Some of these initiatives may even be channeled outside of the legislative process such as some DOE proposals under current administration to protect coal generation. Sorry this might go counter to the intent of this question but I think I'm getting at is that the single biggest factor will be political, and that the voting box is our strongest lever.
Agreed. I definitely felt like it was far more obscure and hacker-y five years ago. I remember things like Beej's guide to Network Programming were (https://beej.us/guide/bgnet/) formed the crux of the content - now there's far more "thought-pieces".
Thanks. I need something I can slip in before a commuted and sedentary day at a desk.
What works for me is being able to toggle between a few different projects that requires slightly different skills and tasks. If I get stuck or tired of one, I can toggle to another project and still accomplish something.

Something else that works for me is letting go the guilt when I don't feel like something something (that's not urgent or time sensitive). If I'm not in the mood, I take a long break and allow myself to properly enjoy it without the guilt. This usually restores my motivation.
It that ever happens I can go back buying newspapers as I did before they moved on the Internet. I bet some of them will always be free, but if only a few of them will be we should be very careful about what we read.
There's nothing I hate, but there are changes I would like to see. The biggest is that I wish it was easier to see when somebody has replied to me.
That's moving the goalpost pretty far. In this context the discussion is whether the protocol is decentralized. Whether the development is or isn't decentralized is also potentially an issue but it's a completely different discussion. Even if bitcoin had only one development team and only one implementation the protocol would still be decentralized.
> In my day job I'm a system administrator of an HPC cluster, and we also do technical support ourselves.

The difference is that you are paid to do that. You are not helping those people out of personal altruism, so wasted time is not lost. You did a successful job nonetheless.

If I on the other hand like to help people with coding problems in my free time, and they don't even bother to properly format the code they want me to look at, I'm wasting time if I still try to read it. My free time, and other peoples time that would need some help too.

It’s a mistake to replace emacs lisp. For a start everyone’s custom code and configurations would have to be modified or scrapped. Package libraries would have to be ported. Much better to just improve it in a backwards compatible way or with libraries. Both of which are happening.

If you have really serious procrastination issues, not only in your work, but in your life in general, if you lose your keys or phone a lot, have trouble keeping up with bills, forget appointments, if you're late to things constantly, zone out at meetings, forget things people say to you almost immediately, concentrate better when either tired or stimulated, have a bad habit of interrupting people cause you'll forget what you wanted to say otherwise, if your house is a constant mess...

Do yourself a huge favor and see a psych who specializes in ADHD. You might be undiagnosed, and treatment could make a significant difference in your life.

If you were smart enough to coast through schooling as a child, and have the inattentive-type ADHD, it's quite likely your ADHD was missed as a child. It's not something you "grow out of" as an adult.

Even if you aren't ready for the psych step yet (it took me years of suspecting I was ADHD before I took that leap), read up on Adult ADHD. If you see yourself in everything you read, see a psych. It's worth it, even just to know you're not "broken" you just have ADHD. Once you know, you can get treatment, and find strategies that work for your brain.
The legitimate way to lower prices in a market is to create a competing product and sell it for less money, not interfere with a creator's rights to sell their product on their terms. The music industry isn't "brib[ing] politicians" to "create artificial barriers" to people creating competing content. Indeed, it's easier than ever to compete with the record labels. Sites like YouTube offer vast opportunities for creating and distributing indie content. The only reason the record labels make any money at all is that they make content people want more than the indie content they could get elsewhere for cheaper.
Without a doubt, the way down voting works.

a) the voter isn't required to identify their reason for down voting
b) it's not just allowed but encouraged to downvote things that you simply disagree with

Those two things wouldn't mean much if it was just a number. But it isn't. The site actively hides comments as they get down-voted, and people down vote things they simply disagree with.

In case you hadn't realised, that's basically a recipe for an echo chamber. I've lost track of how many times I've written/seen others comments that are either factually true, or at least informative while subjective, down voted into oblivion because they don't follow the standing ideals of a large percentage of those who vote.
