>N=36

Since you seem so certain, I have to ask: have you done the math to show that 36 isn't enough to tell you anything in this case?

Depending on the effect size and probability distributions involved, N=36 can give you a pretty respectable picture. It's not good enough to be the final word on the matter, but most papers aren't aiming to be that, nor should they. It seems to me these researchers were trying to scientifically test an idea that floats around coffee communities (I've heard specifically that theanine in your coffee will do this). There's no reason to "go big" right away when doing such a study. You start small to see if there's any hope for the idea, then try to get funding for a larger study by publishing.

>4 servings over a short period of time

The definition of "a short period of time" is relative. In this study, what you're defining as a short period of time seems ludicrous. The participants were given the servings on entirely different *days*, which is far past the amount of time that caffeine or theanine are active.

Finally, the article on HN the other day about bad research was not about small sample sizes, it was about outright fraudulent data. It's certainly possible that this study is a fraud, but, even if we grant that the sample size is small and the delay between administration is too short, that's not evidence of fraud.
you can make it look like TextWrangler too if that helps
That wasn't the argument you made above.
Unless you're doing iOS/macOS application development, you should not install XCode. It takes up tens of gigs of space.

Instead, run "sudo xcode-select --install" to install the basic build tools.

Then, use Homebrew or MacPorts to install modern versions of whatever software you're developing with.
> Not really, It would serve no purpose, only the people who agree with it will agree with the system that outputs "their truth".

Does this not assume that people's minds cannot be changed? I understand the generalization you're making and very much agree with it, but I suspect we differ greatly on the underlying causality.

> I dont think the goal should be such a system because I think is will be flawed no matter what...

Is "perfect is the enemy of good" relevant here, and perhaps also "perception is reality", and some others?

> and also because I think people should be triggered to think and not feed with simplified "facts".

100% agree. A proper system would have numerous goals and features, I imagine you can think of many that I overlook (despite how much more time I've spent thinking about this problem).

> People would also do better if they stop caring about a lot of "garbage" facts they get feed every day if they would actually need to think and build an opinion on something.

This is a fine idea - how might one cause (force) such ideas to manifest in physical reality?

> Instead they get a opinion presented and either take it or reject it based on bias mostly.

Under the current system, agreed.

> This is not useful.

That depends on one's perspective, goals, etc - it is immensely useful to some people.

> It would be better if a person who's not sufficiently interested in the topic simply does not have an opinion on it. At least if at a later point he gets interested he would then not be preoccupied by past "copied/rejected opinions". Many people today have very strong opinion on very irrelevant topics and can hardly reason their stance because it dint "grew" in them it was mostly planted/absorbed from media.

Agree again - so, what can be done to alter this state of affairs? What is the most efficient approach that can be devised and implemented (and, how might one go about that)?

The lack of systems & logical thinking on HN when it comes to certain topics is an extremely interesting phenomenon to me, what do you think?
There’s been quite a lot of world history since the 18th century. Think of some of the events seen from these buildings, like the announcement of the sinking of the Titanic - that building was recently restored. And I think Liverpool has some architecture world firsts - first curtain wall I think.

Plus aren’t other major industrial sites heritage sites? Saltaire? So I don’t see the irony that you do.
Reminds me of accounts of room service at the "Playboy Mansion" were it really was up-and-running at 4am in the morning, which is NOT the case at the Marriott.
The hypocrisy (committed for purely political reasons, no doubt) is that in some of the states the semi-auto AR-15 and AK-47 have been banned while, say, Mini-14, Tavor, and SKS, which have exactly the same capabilities, have not - a decision made simply based on the "looks."

Given that Americans were the ones paying for the IRA to blow up Manchester and kill kids in Warrington, I'm sure they'd be fine.

The sentiment comes from the Labour MP Terry Rooney ("The best thing that ever happened to Manchester"), although it was widely echoed by many people with similar dry humour.
How do I pay to charge someone’s car I’m borrowing for a day or two then without it going to their account? Seems too restrictive. Much better to have an NFC scanner that works with Apple/Google pay services. Taking 3 seconds on a tap to pay system is not a hardship that needs to be reduced.
As far as I know, Red Hat does not provide compiled binaries without a (typically paid) Red Hat license.
Also, consider the relative increase in housing, education, and medical care over that period of time. The inflation adjusted median home was about $178,000 in 1981, It’s $314,000 now.

I think it depends on novelty of an idea, most ideas are slight iteration or down right copy of existing stuff. And if idea is too novel it'd not look like a good idea to begin with, unless it's very obvious, which is even more rare. This is not to say copy ideas are bad, if market isn't dominated by few then copy ideas can become a successful businesses too, but it also means execution has to come through or it will be another me too idea behind the queue.
Unfortunately, at the moment even code access for other public institutions is buried behind many layers of bureaucracy but I have been promised they will start to open up soon enough.
Though trivial, posting because I thought it was funny.

Java and Groovy separately campaigned to have their colors changed on Github, unaware of each other's proposal.

They originally were shades of a similar color, and when the proposal for Java gets merged they will again be shades of a similar color.
Some people, myself included, prefer the taste of coffee, though. So if I can just add some flavorless theanine and get some nice cognitive effects out of the deal, that's great.

Do you have any stats on this? I'm not doubting you, but I often browse this which can show (crowd-sourced) changes to the Supercharger network and it is growing pretty fast:

Welcome to the free market. Republicans want a government small enough that they can drown it in a bathtub, to quote their patron saint Grover Norquist.

What they'll earn is a government so small that it can't be utilized to contend with the entities that do govern their lives, which, being non-governmental, are not constrained by the constitution.

I'm pretty sure that if I found a book I'd just bought was an autographed first edition, I'd keep it unless I had cashflow problems: unless there's some sort of temporary fad going on, its present value is a pretty good predictor of its future value, and if you've bought the thing expecting to enjoy reading it then it doesn't become a less enjoyable read just because it's also valuable. (I guess you might want to be more careful about how you read it.)

But I don't know much about how prices of these things behave. Maybe you expect that by the time you might be wanting to sell, those authors will have been forgotten and the books won't have any special monetary value any more?
"Ask them to explain in detail, a small part of the product. Yes! In detail! ... Everything is explainable in layman’s terms…" - so now you dependent on the teaching/explaining talent rather than code.

I am a native english speaker and I thought the same thing.
I think I would have popped a monocle too, had that been the real example and estimate from a team!

I tried to think up an accessible example that didn't require too much context on the part of the reader, so obviously, as you correctly point out, all the numbers are made up, and I'm trying to use it solely to demonstrate the workflow :)
Excited for this launch! Our customers are doing literal rocket science and every day is an amazing opportunity for us to build the supporting technology they need to do amazing things.

Rocket science is hard, but running your operations shouldn't be! At Epsilon3 we're solving the software challenges of complex operations so you can get back to what you do best - space!
E2EE isn't forbidden per se. But if you are a public communication provider over a certain size you need to provide access upon request if technically possible. It isn't really clear even in the case of Tutanota if they fall into that regulation, however, they had to preliminarily comply anyways: https://www.heise.de/news/Gericht-zwingt-Mailprovider-Tutano...

Healthcare providers operating a Matrix server won't be communication providers to the public, and if they aren't using a web client or some similar crap, breaking E2EE won't be possible. Webmail providers claiming E2EE like Tutanota are imho liars anyways, because Javascript on a website isn't a secure "end" for the encryption.

So use client software that isn't attacker controlled easily, keep your keys private, only encrypt to trustworthy keys and you'll be fine. Matrix ticks all those boxes if you don't use the web client. And the only legal way in for German law enforcement would be to infect your device with some trojan ("Bundestrojaner", like e.g. NSO Pegasus).
It was thoughtful of Microsoft to re-license Linux as MIT.

Very cool. I could see this as useful. My guess is that it will be very popular. If it does take off, it might be good to even break the post into multiple based on domain or something.
You've always been able to run a Matrix server completely separately from the wider federation, and there are loads of them out there (we estimate around 35,000). Unsure what "federated" authentication problem you're thinking of.

The only thing I can think that you're referring to is the question of how you track the keys used by servers to sign the events they send. If the server is offline, and you've never heard of it before, you still need a way to check their key. We don't currently use CAs for this, but instead you grab a cached copy of the key from a trusted server: https://github.com/matrix-org/synapse/blob/a743bf46949e851c9.... This is a bit of an edge case, as in general servers whose events you care about will typically still be online - or you'll know their signing key back from when they were on line.

The longer term solution for this is https://github.com/matrix-org/matrix-doc/blob/rav/proposal/r... which includes the sender's public key in the event (by making it the sender's identity) - and we're working on this as part of P2P Matrix currently.

I rarely write in a book besides my name in pencil in the front. But when I see an error that I can't ignore, I'll make a copyediting mark or note in the margin so I can move on. Very occasionally I'll get a book that I need to argue with, and then the margins get filled, sorry to anyone who eventually finds these.

I think my reluctance is mostly about keeping a book in the state I got it, since I do frequently mark up interesting sections of PDFs in my e-reader.
Apart from a few minor quirks (pop-under call dialog is most annoying), for me Teams just works.

Just today I had over a dozen different calls, most with screen sharing, several with participants joining and quitting during the call. Several included me taking control of the other's screen. We even swapped screens over a dozen times between participants in one call.

I chatted a lot with my coworkers (corona home office turned into summer home office) including sending screenshots and similar.

I participated in discussions on the team channels, again with attachments.

We used the Excel integration to edit a spreadsheet attached to a meeting in collaboration during the meeting.

I took a couple of calls on my mobile phone while I was making lunch, as well as chatting, continuing the chats seamlessly on my desktop when I was done.

This all just worked. This is more or less a typical Teams day for me these days. However based on the comments on HN, clearly it seems I'm an outlier.

Yes the UI is lacking significantly in some areas, and there are some annoying bugs, but "total dumpster fire" isn't what I'd call it.
German government IT is far removed from being a monolithic entity. There are a lot of different actors involved with different priorities.

In this case law enforcement can simply request the data (as long as such a request is legal) at either end. No need to attack the connection in between.
Getting a bit off topic but I definitely have some strong associations between concepts and the time & place or people I learned them from.

Do you not know anyone who has had a life-affecting injury or was killed while in a car? Not saying scooters don't have their risks, but pretending cars are a paragon of safety seems to be the result of availability bias.

> a glorified CRUD app

I feel like this can be said about most application development nowadays, especially anything web based. It's one of the reasons I'm losing steam as a web developer. It feels like no matter what project I do or company I work at, I'm really just doing CRUD all day. The only variations are the names of resources and the slight data manipulation you do between the HTTP request and storing it in the database.

Has anyone else experienced this same feeling?
7MW is about half a high speed train at maximum power, but that's using a 25kV supply.

But running the cables is presumably easier when the railway has that convenient strip of land all across the country.
In your experience, what is the brand with the least bitter powder?
Not at all. The list of things you can claim for is very limited, and the majority of them are automatically applied. Having to actually contact HMRC is a rarity. If you are salaried employee with no extra cash coming in, you don't need to do anything.

Another example of how the system works - if you are working two jobs, both as a regular employee, HRMC will instruct your employer as to what your tax deduction should be for that paycheck to make sure that things are balanced. For <some large number>% of people, this will be correct, and if it's not, it will rectify itself over 2 or 3 pay periods. If that's _still_ not enough, a phone call to HMRC (usually taking less than 10 minuts for the two times in a decade I've had to do it) will resolve the issue in your next check.

Thank you for these points! I respectfully disagree :)

A raw Terraform module is quite hard to reuse out-of-context for someone who isn't familiar with devops / sysadmin concepts. What's a VPC? Security group? ACL? Each service exposes a bunch of config options that won't make sense to people who are facing it for the first time. TF mimics AWS interface, and it's more like a pilot's cockpit than a car interior. All tools imaginable out there, but you got to know what you are doing to use it.

Targets on the other hand are exposing high-level concepts only. How many services? Is it container or a function? Enable or disable database? Got it, starting building. More like a car interface or a phone UI which you can figure out by doing.

Current implementation of Targets is very simplistic. It just does the job but not much more. In Targets v2 we are planning to introduce proper dynamic generation with a "stack state" API that would allow to create truly incapsulated, smart components that would adapt to a number of environments.

The Tesla charger is more elegant than CCS, although I anticipate the following problems:

1: With CCS, the physically larger connector communicates to the customer that it's a high-speed charger. A lot of people don't understand the difference between slow and fast charging. (You can even see it in this thread where people don't know that they can't plug their Tesla into a CCS charger.)

2: CCS has bigger pins, which means it can carry higher amperage. There's no way to work around that situation with the Tesla connector.

(The bigger pin difference also, ironically, boosts the VHS vs. Betamax analogy. Betamax's biggest problem was that the tapes were physically too small, thus cutting either playback time or picture quality.)
Yes, I think so. I drank a lot of (diet) cola at some point, like 1 gallon a day. Never got any issues similar to the ones I got from coffee.
I have a lot of concerns about AI moving into spaces that involve human life and death.

With that said, I think you've highlighted one possible outcome, but it makes a few assumptions that might play out differently depending on how the tech is implemented.

Imagine, for sake of argument, that the AI is just "part of the team". It doesn't replace a doctor, it doesn't have authority over doctors, it's just another signal. If applied in this way, then you can still:

- Ask for a second opinion

- Go to a doctor/team that doesn't rely on AI

- Consult a different / (better?) AI

I realize you're focusing on an outcome where AI replaces humans in the field, but I'd hope humanity can find an implementation that can both leverage the benefits of the tech while not throwing out the core disciplines of medicine in the process. It's reasonable to be pessimistic about this given the tech-run-amok issues prevalent in 2021, but I still have some hope.

Also imagine the possibilities of AIs sharing knowledge with each other. This has its own semi-terrifying implications, but I don't necessarily think we should conclude that the only outcome is a single AI to rule all AIs (and doctors).

Of course, I could be wrong as well. But I don't think all roads lead to doom.
There's a ton of time wasted in miscommunications and lost paper records or illegible handwriting on test logs.
