Thank you for this. I'm tired of the FUD surrounding RAID. It seems that the same anecdotes are passed around without any vetting, and it helps nobody.

The initial phrasing about heavy metals sounded to me like it was referring to the brewing process (without being specific as to which one).

At first approximation, I'd be surprised if agitating heated water in the presence of particular matter that increased its acidity, then running it through a fine woven filter, didn't have some net effect.

As for the exact mechanism and efficacy, that's unfortunately buried under 10,000,000 search results for coffee enema products...
I think of it as a drug that adapts us to modern industrialized life, while our genetic dispositions are still half in the hunter/gatherer stage.
>Sometimes, Programs That Use Transactions… Are Worse

I understood that reference
I just got a domain for the first time yesterday, and decided to go with migadu.com instead.

You can forward mail to/from gmail with it basically the same, it has a very low sending limit on the free plan (but I'm not sure if that applies to mail forwarded from gmail), and it claims to attach a footer on the free plan (like forwardmail.net does), but it doesn't actually seem to do so to mail forwarded from gmail. https://www.migadu.com/en/guides/gmail.html

Meanwhile it has it's own webmail/pop3/smtp servers so it will be easy to move away from gmail entirely in the future.

I also just really liked the tone of the website, I have a lot more confidence in them not doing scummy things than I do in forwardmail.net not doing scummy things (though that is just based on reading a website, not the most reliable indicator ever).

Anyways, we will see in a few months if I think I made the right choice.
How much time do you spend reading the book vs the other activities?
I said this in another comment, hope it clarifies my understanding:

Sure, I get smalltalk, and I now understand the dichotomy of book club types. Some people are expecting book clubs to be casual and others hardcore. Our definitions are not the same so our conclusions as to what book clubs should be are also not the same. I like both approaches but I like them to be delineated. If I'm with my friends I can appreciate it being a social gathering with a theme, but if I attend a "hardcore" book club, well, I expect it to be hardcore, talking about the book itself for most of the time.
You're not wrong but... A disease with 50% mortality in an age with a 50% child death rate compared to a disease with 1%ish mortality in an age with (here at least) 0.01% child mortality. Sort of comparable...
The deepemoji one is fooled by "was my flight delayed? no.". I feel for the computer when it meets that one "do I speak in questions?" person. chuckles.

On a more serious note, Hinton and other alluded to the need to restructure NLP studies as to focus more on the nature of recursion within language, which is basically what Chomsky has been saying for decades. It's interesting to see whether they converge.
that's surprising and I guess you're relatively young and don't have kids because I've actually still heard it sung by kids in kindergarden. There's also Bach's coffee Cantata in a similar vein, and quite a lot of fiction dictated to the allegedly detrimental effects of drinking coffee.

And sadly often a lot of it is tied to the image of the "sickly Turk" which is a popular stereotype attached to most things imported from 'oriental' cultures. You may remember debates about the hookah craze a decade ago or so.
The history of humanity is very literally one of violence, conquest and subjugation. Your comment falls into the fallacy of presentism:

> uncritical adherence to present-day attitudes, especially the tendency to interpret past events in terms of modern values and concepts.

History is not divided into victims and perpetrators in this respect, the only distinction you can make is that at any particular point in time any particular group may have been on the winning or losing end of it.

> colonialism has devastated cultures across the globe, and we should acknowledge that

To what end is it important to acknowledge this? The history of all people is drenched in the blood and atrocity of the past. Colonialism is not different from any other form of historic state or empire building.
For the benefit of everybody else, #+ does feature checking.

The Common Lisp standard defines a standard "special variable" (kind of like a global) named * features * (shouldn't be spaces, but HN italicizes it otherwise), and #+ (and #-) take a "feature expression" and conditionally execute the expression that immediately follows it when the feature expression is true. If the feature check is false, the next expression is ignored.

For example:

#+freebsd(print "This is FreeBSD")
#+(not (and 64-bit linux))(print "This is not 64-bit Linux.")
#+quicklisp (ql:quickload :some-library)

The CL standard lists a few standard features (:common-lisp, :ieee-floating-point, etc.) but for the most part implementations and libraries define their own.

It's not perfect, but works well enough in practice.
Show HN: Intrgr – A new way to read/discover articles and blogs
Link: https://intrgr.com

Hey HN,

Intrgr is a way to discover, submit, and discuss articles from around the web with other readers; to be kept up to date by article recommendations--of not just news but all text content; to declutter websites; and to find related articles of any content Intrgr can parse.

The recommendation algorithm weights blogs better, if you reply with a blog url(s) I can add it to the global article source pool.
You are ignorant of reality, and the first thing that you ignore is that you are ignorant.

With Lisp you don't even need to write lisp code. You can write java, c++,c, swift code... using lisp.

That is , you can write lisp code without people realizing you are writing lisp code. The only thing they will notice is that your code looks almost too perfect, too well formatted and justified, are extremely productive and never make mistakes.

To be quite clear, I'm not saying that only US goods need to be bought by Germans and Chinese. Those consumers are generally thrifty overall relative to their share of the global economy, and a global economy based on one country's consumer demand is simply not going to be a healthy one.

High German savings was one of the things that led to the Euro crisis, since you cannot simultaneously run trade surpluses with all your neighbors and then be surprised when they are running deficits as a result. In the same vein, Chinese over-saving has led to a domestic property bubble that is a house of cards waiting to fall apart once people can invest their savings in something that isn't an apartment.

As far as your point about global goods, I don't think that China, a place where hundreds of thousands of infants were poisoned due to illegal substitutions in baby formula, and people get told to look for reused "gutter oil" in street food, has a leg to stand on when it comes to food safety.
In Poland tele consultation in healthcare were rare. Now it is the norm including drug prescribtion and paid sick leave.

Some consultations will go back, but a lot of changes will become the new norm.
It depends on the situation.
It's not that bad, check out the Serenity OS project (on Youtube).
Thats the story beeing told. Since I havent seen it, my critical mind starts to think, that this is actually a myth. Do you know of any published (in the sense one can reas the code) examples that show this claim (and the reddit v1 is not such an example)

(Of course anybody can chime in, it should be actually easy, if the claim that here the experts are lingering around)
Amazing mechanics, there is a lot to learn by just examining the mechanism of these. As a kid I had access to one, my mom had one at home. I distinctly remember how fast the ball moved because I got a nice 'J' imprint on my pinkie trying to see what would happen. That hurt (predictable). That taught me not to mess with live machinery and to have respect for things that move faster than you can follow with your eyes.

>As far as reliability, you can't compare almost any COLO location with an AWS data center.

Why not? We had much less downtime than AWS' NoVa DC while coloing, and I don't think our DC was exceptional. AWS is probably much more competent, but they're also trying to build something much more complex than your average small-scale colo setup.
No. That's so false it's shocking. The name of the virus comes from the fact that it is genetically a corona virus. There are 7 known corona viruses that affect humans and every single one of them are respiratory.

What ever data 'sources' you're reading are wrong.
I implemented something similar last year: https://github.com/kccqzy/green-threads/blob/master/green_th...

Actually implementing it was quite fun and I encourage every enterprising systems engineer to try. My implementation even supports growable stacks (up to a limit of course).
I used to think the same thing, but as I grew older, I realized that that concept doesn’t apply to all people. Sometimes what comes off as hyper intelligent is really just smart people putting the time in to prepare for specific occasions. It is unlikely that Bezos met with the author without having done a lot of preparation and research into factors that he felt were important. Narrative being one of them; he is a very public figure after all.

Of course I could be wrong, but I like to think of it this way - Do not reduce to genius what is often the result of hard work and preparation.
Tipping and the shaming culture around them is what I believe will ultimately kill delivery apps and a lot of in person dining in a post covid world. There isn't a single person in my age range I've ever met that didn't once work in a restaurant (where the owner under paid them) that thought of them as anything besides a sneaky way of the owner extracting more money from the consumer. If the person is from another country or lived abroad the hatred for tips is even higher. Tipping for older adults was once an optional item for exceptional service to the under paid but it is now just something you're forced to do by the owner for their employee doing their job competently.

I absolutely don't think ghost kitchens are the wave of the future in the city when most people would actually prefer to save five to ten dollars on the delivery plus the arbitrary tip in nearly all situations besides being inebriated.
For reference:

> Amazon, a company that many would consider an expert in e-commerce and logistics, tested the market and left about a year ago.

https://www.nytimes.com/2019/06/11/business/amazon-restauran...

> Since it started in Seattle in 2015, Amazon Restaurants has struggled to gain a foothold in the restaurant delivery market. Together, UberEats, Grubhub and DoorDash control nearly 80 percent of the restaurant delivery business, according to the research firm Edison Trends.

> Still, Amazon Restaurants is unlikely to be the company’s last venture into restaurant delivery. Earlier this year, Amazon invested heavily in Deliveroo, signaling its sees long-term interest in the area.
This sounds awesome and would be something I'd definitely join. (Sadly not being based in Barcelona though :)

What books did you read and how was this event initiated?
Are you sure they were warning about drinking it, and not its effect of worsening bruxism?
Absolutely this.

I have my headphones at what I consider to be a reasonable volume level, yet this website was so loud that my ears are ringing.

Is it just on my end or is there some explanation for the (perceived?) higher volume?
I've been off caffeine for going on 40 days now. Work/health were suffering and I needed to hit the reset button. Some days its rough, but on average the change is worth it now. Last week I was able to deal with an extremely stressful event at work without losing my calm. If I had been hopped up on my usual morning brew under similar circumstances, I probably would have made some serious career-altering mistakes (not necessarily my career).
I'm all for banning grubhub, ubereats, postmates, and doordash. If people want to order take out, let them get off their lazy ass, come down and pick up their own order.
The trick is framing. Simply frame it as "put America back to work" and "making it easy to work" and you sidestep most of the red scare trigger words.

Part of the decline of the American left in formerly blue collar areas, IMO, is simply that it has become more academic and less attempts at sloganeering or actually doing work to reach out to disaffected people; polls keep revealing that Americans actually like the nitty gritty of the policies but that the marketing of it sucks.
coffe does not dehydrate. that myth was debunked long time ago.

the reason you get a cup of water to your coffe at cafes is to drink the water BEFORE you drink the coffee. the water helps to neutralize any (bad) taste in your mouth (eg after a meal) so you can get the most out of the aroma of the coffee.
Exactly, which is why the expert information is teased out in a couple in depth blog posts.

https://www.michael-noll.com/projects/

Does a very good job in this regard. I think if you have a consulting agency where you can train or lead on multiple projects, then a book could be a very good sales vehicle.
Nice, this is like an open-source Firebase Authentication. I was wondering whether such a solution existed because, even as Firebase Auth is free for unlimited users, it still is a hosted service whose terms could change at any time.

He was incorrect based on the existing evidence.

Sugar-laden diets combined with both a mineral poor diet (ergo, no dental remineralization) and a constant subclinical dehydration (did you drink your gallon of water today? no? saliva is the vehicle for said remineralization, and is one of the first to be hit during early stages of dehyrdation; water is required to maintain the pH of your mouth) is bad your teeth.

The worst coffee can do is stain already poor enamel. Coffee is hardly acidic, and its a myth that its more destructive.

Now, if you drink your coffee with sugar? Thats bad, learn to drink it black.

https://www.ada.org/en/~/media/ADA/Public%20Programs/Files/J...

Anything on this list that is below a pH of 5 you should strongly avoid. pH is a log scale, so, pH of 5 is 10x worse than 6, 4 is 10x worse than 5 or 100x worse than 6; the hydroxyapatite in tooth enamel starts to dissolve at 5.5, and coffee is only 5.11, well within your mouth's ability to handle.

If he warned you because you suffer from bruxism, not because of tooth decay, for most people, just follow the normal rules for coffee that everyone else should follow: avoid caffeine 6 hours before bed.
People who aren’t super healthy don’t typically feel like drinking lots of caffeine. I think that’s a more likely explanation than caffeine having tons of assorted health benefits.

How can one write C for example using lisp? Are you talking about compiling to C?
They are. I created these for several reasons.

- Reduce friction for unregistered users to see content.

- The instance you use, only aggregates from specific instances of their choosing. You might miss content from other instances.

- Work on custom curation / discovery features in the future.
I'm not sure how to resolve this disagreement. It just doesn't seem plausible to me that restaurants competing against each other in a free market would cause them to all go extinct.
It's simply a huge memory regression, thus a bug. Low memory devices cannot use gnome then. Maybe they do care about low memory devices, but I doubt so.
That's a really good point. Is it possible yet to define a set of enforceable restrictions for new C++ code that makes it memory-safe?

There are some non-lint type things that would help in a safe mode. These all need type information; they're not just syntax.

- Can't keep a raw pointer. If you create one, it has to have local scope and cannot be copied to an outer scope. This is like a borrow in Rust, and limits the lifetime of the pointer. Most uses of raw pointers involve calling legacy code, and don't need much lifetime. Most trouble with pointers involves them outliving the thing to which they point.

- Can't read into or memcopy into any type that is not fully mapped. That is, all bit values have to be valid. Char OK, int OK, enum not OK, pointer not OK. This is better than prohibiting binary reads or memcopy, because programmers will not be tempted to bypass it.

- Casts into non fully mapped types are prohibited. If you need to convert something to a non fully mapped type, it requires a constructor, with checking.

That gives a sense of the general idea. Do enough analysis to see if something iffy is safe, and prohibit the cases which are not easy to show safe.
Weird! Where I am in Germany they all say 2 metres.

As a foreigner, it seems to me that the problem in the US is that too many people live alone.

My favorite pizza shop in northern Germany has a minimum order of $22 and charges $4 in delivery fees.

For one person alone, that wouldn't work. So you order together as a family. Or together with your flatmates in university.

I’m still waiting for Jepsen to put Confluent’s “Kafka provides exactly once delivery semantics” claim to the test.

Since they’re claiming something provably false, it’d be nice to have some empirical evidence as such.

My kids have been having their music lessons (cello & viola) remotely since the quarantine. For the advanced student, I can see 50% of lessons workable as remote, but not more than that. My kid may switch to every other lesson remote (two lessons per week at 45 minutes each).

For the beginner, it doesn’t work that well, but I suppose it’s better than nothing.
How many pen companies are there? And yet, people still make pens. It's the same with competition. Don't worry about it as inevitably you'll be making different choices throughout building and selling your product that won't be replicated by others. Some customers will like your choices over other companies', and that's why they'll stay your customers.
Could you give me an example of a real-world software engineering task which takes “weeks” in Python and minutes in Lisp?
Show HN: Video Slide Deck Pitch
Sending a link to a slide deck or PDF doesn't allow you to communicate your message very well. So, I recently added the ability to embed a Google Slide Show into a video message in order to record a presentation and communicate what you're building.

All it takes is to copy & paste your published Google slide link into the video creator and you'll be ready to start your recording.

You can save it to send later or create a more personalized recording and send it as a message as well.

I'd love everyone's feedback and thoughts. Hopefully, this will help you communicate your mission & raise money for your startup.
It's not a fallacy per sé, because people have limited capacity to process information. This is nessecary to make sense of the world, and narratives as a whole. The fallacy would be to over simplify where there is no need for it. It is more of a question to what extent one must be detailed enough to convey a narrative meaningfully with its nuances.

That you can sleep does not imply you get the same quality of sleep. It's well known that alcohol and caffeine reduce sleep quality. So even if you can sleep after having a coffee, it's probably still not a good idea. Have a decaf if it's after 3pm.

> it's simply not possible for me to do something like pursue a PhD in biology

Becoming an expert is not the same as getting a credential. It's perfectly possible to become an expert in whatever particular condition you personally have, without getting a PhD in biology, or indeed any relevant degree. Indeed, since you say you are getting results, I suspect you are becoming an expert in your particular condition, whether you planned to or not. My wife has a chronic illness and she has been forced to become an expert in it (with no relevant degrees at all) even though she would much rather have spent the time on other things.

I'm glad you are; that's the most important thing.

Some people order delivery because they don't have transportation. Others order delivery because they are handicapped and, for example, in snowy, icy weather, their wheelchair plus snow and ice and so forth mean going somewhere is not very feasible at times.
