Feces comes in all manner of consistencies and textures. There is a range of consistencies for which bidets are wholly useless. Specifically, sticky ones. For these, you need friction from a solid, high-surface-area object.

I'm sure you've had brown streaks inside the bowl that could not be removed in N flushes, but a simple toilet brush made quick work of the matter.

To use your handwashing analogy, try removing crisco, or some other substance that adheres to your hands with a stream of water. Now try physically wiping it with a paper towel. The towel will win every time.

This is to say nothing of the fact that it's quite nice to leave the bathroom with dry hindquarters rather than a bad case of SA.

Researchers are finding that COVID-19 testing has roughly 33% false negatives.

https://www.wsj.com/articles/questions-about-accuracy-of-cor...

The LabCorp test is not FDA cleared or approved and is being used under an emergency act.

"Testing was performed using the cobas(R) SARS-CoV-2 test. This test was developed and its performance characteristics determined by LabCorp Laboratories. This test has not been FDA cleared or approved. This test has been authorized by FDA under an Emergency Use Authorization (EUA). This test is only authorized for the duration of time the declaration that circumstances exist justifying the authorization of the emergency use of in vitro diagnostic tests for detection of SARS-CoV-2 virus and/or diagnosis of COVID-19 infection under section 564(b)(1) of the Act, 21 U.S.C. 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner."

The Quest test is not FDA approved either: https://www.questdiagnostics.com/dms/Documents/covid-19/SARS...

"It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID-19. This means that you could possibly still have COVID-19 even though the test is negative."

Due to this, it's hard to trust test results. It's a best effort and not perfect.

After seeing Rick's Re:invent talk, the one where at about minute 40 everyones' heads exploded, I emailed him (I'm in a very far away other department of Amazon) to ask him for more, because everything he was saying was absolutely not the way my group was using DynamoDB (ie: we were doing it wrong).

He could have ignored my email entirely. He's a busy guy, right? I wouldn't have held it against him at all. Instead, he was super nice, provided me with more documentation, and honestly was just really helpful.

If he recommends your book, I'm buying it.

In Common Lisp, and similar dialects, the module concept is certainly not tied to a file. In fact, there is no module concept. Packages work at the symbol level. Any file can use symbols from any package.

The concept of a compilation unit is closely tied to that of a file. That's not even remotely the same thing as a module.

Even so, Common Lisp has with-compilation-unit which allows multiple files to be compiled together. They still emit separate files, but for the purpose of diagnosis (warnings) they are considered one unit. In concrete terms, complaining about undefined variables and functions is deferred until the entire compilation unit is processed.

Top-level form processing is deliberately contrived in order to make certain practical situations conform to obvious expectations.

For instance, suppose that we have a top-level form:

(progn (defmacro foo ...) (foo))

this cannot work if the entire form is macro-expanded first, and then evaluated, because then (foo) is undefined.

The eval-when control over the top-level is also very important in the face of compilation.
I partially agree that the UI isn’t great for the most part but I like the notification area.

It must be so hard to get a group of designers together that will make something on the level of iOS or Android, but do it for an OS that will be used by (most likely) very few people.
I want to like Jitsi, but I can't. I've been testing it out on a variety of servers, bare-metal and cloud with Debian and CentOS. Regardless of platform, it doesn't scale, it eats memory like peanuts, and can saturate even 10GbE network connections. The service, as opposed to the server, clearly works well. But, the service doesn't have anything like the load that Zoom, Teams, Hangouts, etc. must deal with.

Every time I learn more about seL4, I fall a bit more in love with it. Can't wait to see what people do in terms of integration over time.

I think it would be super cool to see L4Linux updated again, and on seL4 this time; maybe start shifting device drivers into tasks behind a low-overhead abstraction. We're going to have Linux and POSIX applications for a loooong time, but maybe we can make incremental progress toward something a bit less braindead.
Why? They've already tried to mix mobile and desktop UIs with strange results. Gnome Shell has never been usable on touchscreens due to poor open source multitouch drivers. There aren't any well-known tablets or phones running Gnome, to my knowledge. Why keep going this direction?

I want Gnome 2 back.
Yup. GNOME3 works quite fine in detachable and 2-in-1 laptops, barring the usual sorts of hardware issues. And it's the only system that I could see working in a Linux-powered phone or tablet (w/o keyboard component).
Yes in an ideal world I should just be able to write to Bill and he will have the time to consider my proposal seriously. In the real world the only way to get the attention of someone like Bill is to have someone he takes seriously bring it to his attention. Hence the post here.
> The 22nd Amendment limits only who can be elected to the office of President. Since a VP becomes President through devolution, not election, it doesn't limit who may serve as VP.

So it would be constitutional to give Obama a third term through a Putin-esque sham where Biden runs at the top of the ticket then immediately resigns after taking office?
This is a lovely essay, but I think it goes a little too far in claiming that the electromagnetic field is intangible or immeasurable, in slightly forced analogy with quantum mechanics.

> We now take it for granted that electric and magnetic fields are abstractions not reducible to mechanical models. To see that this is true, we need only look at the units in which the electric and magnetic fields are supposed to be measured. The conventional unit of electric field-strength is the square-root of a joule per cubic meter... This does not mean that an electric field-strength can be measured with the square-root of a calorimeter. It means that an electric field-strength is an abstract quantity, incommensurable with any quantities that we can measure directly.

A more conventional way to think of the dimensions of the electric field is [force]/[charge] (e.g. units of Newtons/Coulomb), and you can observe the electric field by observing the force it exerts on a charged particle through

f=qE

for example by observing the trajectory of an electron in a cloud chamber.

Dyson says that the square of the field is a measurable energy density, but it’s arguably harder to measure an energy density than it is to measure a force.

Dyson’s point is much more true for quantum mechanics, where the only measurable things seem to be quadratic combinations of the wave function, and I do like the analogy he points out with electromagnetism, but I think he oversimplifies a bit to make his point.

My company has been trying to find a solution since the Coronavirus hit. (We're not used to working from home)

We were using Slack's built-in conferencing at first, but aside from the quality being generally bad, there was a 15 person limit, and we're ~ 17 people.

I didn't want us to use Zoom with everything that's going on, so I suggested Google Meet. We tried it, and it worked, but not well—people's voices would frequently break up and become hard to hear.

And so we tried Zoom this past Monday.

It was incredible. I could actually hear and see everyone. I'm not happy about all their issues, but damn their product is just really good.

So if I ask an American to show me his "Handy", he knows that I want to see his "mobile phone"?

Because that's what "Handy" means in Germany. It's actually "mobile phone", hence the confusion. I learned that "Handy" is almost exclusively used in Germany.

I've been helping quite a few people set up Jitsi lately. The software works reasonably well, although documentation is lacking and a lot of configuration options are named terribly, but one thing I've noticed is people's expectations about bandwidth usage are way lower than actuality, especially outbound from the server. But a bit of napkin math suggests that Jitsi isn't doing anything fundamentally inefficient here; one high-res stream plus N low-res streams transmitted to N participants is just a lot of bandwidth.
While GA is free Photoshop has one of the most insanely bloated pricing approaches for casual usage - the fact it's handed out like candy to students (and various institutions allow this instead of familiarizing students with alternatives) is the only reason its kept such a dominant market position.

If your boss asks you for some analytics about site usage the first thing searching the web will turn up is GA and you can have it set up on a test env in less than half an hour including acquiring an API key and reading enough docs to configure it.

Over the past three weeks I've tried a few different conferencing solutions, including jitsi. I'll give it another try with this update.

My use case is I take weekly music lessons, and now they are virtual. The problem is the DSP done on audio was designed for speech. If my teacher is explaining something then plays an example on his bass, it usually sounds terrible, maybe even inaudible.

I send him pre-recorded mp3s of cover songs; ideally he could listen to it and I could comment in real time about places where things could be improved. Instead, if he is playing any music on his system, I hear nothing -- no music, no talk. It seems like the software thinks "Hey, this participant is listening to non-conference audio, so I'll just mute him (at least on skype). I'd love there to be a half duplex audio button so none of the DSP shenanigans are needed, and a high quality audio stream would be sent.

Ask HN: What Is Your (Big) Data Architecture/Tech Stack Like?
What technologies, and patterns, does your system use in order to process, store, enrich, analyze and serve data and insights? How do you manage your infrastructure?
Can you blame them? Most users and purchasers (at a lot of companies the people making purchase decisions aren't actually the users) don't really understand or care about how long real engineering takes. As long as they made a decision to pick a vendor based based on the principles of Cover Your Ass it's all that matters.

It's another primary reason why so many "enterprise" companies purchase Redhat over running CentOS.

I use a simple local catch-all SMTP server for testing. I install it on my test machine listening on some non-SMTP port (default is 2000), and then use iptables to make all connection attempts to port 25 end up at the catch-all server.

Here's the iptable command: "iptables -t nat -A OUTPUT -p tcp --dport 25 -j REDIRECT --to-port 2000"

The catch-all server is ridiculously simple. It just responds with a "220 hello" when connected to, and then just reads input line by line, logging all input to a file. It only knows about two SMTP commands: DATA and QUIT.

On QUIT it sends "221 bye" and closes the connection.

On DATA it sends "354 send the message" and then just reads the data and logs it to the file.

Anything else? It just sends "250 OK".

Note that this is pretty useless if what you are trying to test is a mail client, because you cannot test error cases. The purpose of this SMTP catch-all is for testing the content of messages your software sends, not for testing the process of mailing itself.

Each connection is logged to a separate file.

The source is a single Java file. Here it is if anyone wants it [1]. "javac SmtpSink.java" to compile. "java SmtpSink" to run. Messages are stored in the "msgs" directory, which you should make before running it.

I'll bite: maybe it's good at identifying obedient drones and letting them through :)

It trips up the normies in my life often enough that I suspect being technically inclined is actually a net advantage because it makes you quick to detect the problem and quick to apply workarounds. Those advantages are significant enough to outweigh even the cost of the semi-regular dance where I try to protect myself and Google jerks my chain.

> Have you considered

The fact that I phrased my proposal as a tradeoff should have strongly hinted that I did, in fact, consider.

> Wouldn't that remove any real gains from being vague with tips & tricks?

One bit of information -- locked vs not -- is hardly the same as disclosing the inner workings, or even the information inputs, of the classifier, and smart botters have access to that bit of information anyway because they've built a gaslight detector by leveraging their legions of diverse bots and endless supply of dirt cheap human labor.

Gaslighting humans is really bad. A minimal courtesy would only cost a sliver of efficacy, and ReCAPTCHA still rejects it. That decision earns it the bad will directed its way.

If you lose an animal just before you take it to market you've lost your entire investment in that animal. I wish I knew the numbers exactly but any $0.00 ROI is going to have a big impact on a portfolio's average return. Also, consider losing an animal also means any animals it could have produced as offspring are also lost. Granted, most males are castrated at some point iirc.

> It is recommended to use official WireGuard software whenever possible.

I don't agree with his sentiment at all.
With OpenVPN Viscosity is by far the best OpenVPN client and both the 'official' client (OpenVPN) and the open source alternative (Tunnelblick) are buggy and have crappy UI.
I'm hoping Sparklabs either repurpose Viscosity to include WireGuard as well, or write a new client specifically for WireGuard (which I'd happily buy).

Edit: wow, what the hell. I guess HN hates improved clients with a violent passion.
It could be worth reporting some feedback to them directly, if you haven't already?

They're quite responsive on GitHub ( https://github.com/jitsi/jitsi-meet ) and I'm sure additional details regarding any bottlenecks would be appreciated.

> If I used to produce 100 units per month because that's how many I could sell, but now I know I can sell 10000 units per month, that is incentive enough to increase production.

This assumes that you can actually scale production to 10,000 units (a plant that can produce 100 items a month is not necessarily one that can produce 1000), that your typical channels can absorb said production (if they need to hold inventory, they likely cannot), that you have enough packaging supplies for your increased inventory (a real problem being encountered at the moment), the list goes on. Supply chains are not linear. You can have valid issues with price gouging despite this fact, but simply saying "increase production, problem solved" is an extremely uninformed position.

There is only a widespread belief that politics is banned on HN. No actual rule.
Now contrast with https://en.wikipedia.org/wiki/Special:Diff/320402189 , the widely recycled Wikipedia edit and the claim that had to be explained; which that does not even support, let alone explain.

The Armando Stettner named in https://en.wikipedia.org/wiki/Special:Diff/320396668 and other edits by the same person is the person who told the "sorry excuses for engineers" anecdote about xyrself, recorded in A Quarter Century of UNIX by Peter H. Salus.

The irony is that there is better, more specific, documentation of M. Cutler's opinion of OS/2 (specifically its mutex mechanism) than there is of M. Cutler's opinion of Unix.
Zoom had the same security issues with half the traffic. Acting like usage causes them is disingenuous.

Technically speaking, zoom has shown off great and remarkably stable/scalable features.

But that is orthogonal to whether they are putting people at risk (e.g. not-so-secret therapy sessions) or lying about their feature set (clearly claiming to have end to end encryption).

My guess is that it's purely politics, and there's a large number of users who just don't want to have purely political discussions.

HN sometimes has decent threads about political policy on non hot-button issues, but threads about political personalities are unlikely to go well and are thus not worth the trouble.

You can have issues with the economics of supply and demand, but as you outline very well, there's not really a button that just scales supply when you need it.
