It’s sad that RSS (or Atom) as a way of consuming web content (not considering podcasts) has become a “power user niche”. In a centralized world where most people get most of their (fake) news from Facebook or WhatsApp, RSS/Atom doesn’t stand much of a chance for gaining broader mainstream use.

The biggest advantage of using an RSS reader is that it’s a single place that has content ready for you to consume in a list based interface. The web browser interfaces of websites, on the other hand, have all kinds of crazy and trendy layouts where content is a third class citizen (first class and second class are both reserved for ads). This makes skimming easier and quicker. There’s only one way to skim in an RSS reader regardless of which site’s feed you’re looking at. You don’t have to go through the mental exhaustion of skimming several different website layouts, fonts, colors, etc.

I use a couple of RSS apps across devices, and at least one of them is running all the time to refresh content periodically so that I don’t miss something (I know there are online aggregators, but I haven’t found something that I liked and preferably very cheap too). I don’t try to read all the articles across sources since that’d be an endless effort, not to mention completely wasteful. I skim through, read some, star some for future reference or use and mark the specific source (or all) as read.

One thing I hate about many sites that provide RSS feeds is the lack of full text content in the feed. It’s always a jarring experience to open the link to the full content and experience chaos that’s in complete contrast to the reader experience.

On Mac and iOS, I’d recommend NetNewsWire (free and open source). In the past, I’ve used RSSOwl (cross platform) and Vienna.
> As someone following Bitcoin for a long time since just after genesis, I can assure you that replacing cash and credit cards was never on the original agenda but instead a byproduct of the goal.

As someone who was also there, I stopped reading at this point. The things getting circulation were bold predictions about replacing cash and credit cards in daily life and anyone who questioned that inevitability was dismissed as not understanding it. Everyone knew it was an attempt to dress up “use your money to make me rich” in a more noble guise but that doesn’t mean it didn’t happen.
Right. I struggle to see how anyone in this thread is seriously comparing their PC with ZFS to my server with 12x 3.84TB SAS SSD and a PERC 740 controller. Yet they are with absolutes like “Hardware RAID is dead”
This is certainly not a study. And certainly shouldn't be taken as good data of any kind, but it is interesting:
https://www.livescience.com/coronavirus-in-pregnant-woman-hi...

Sure as hell isn't random (all pregnant women... so all women for one. All at the same hospital is another).

"Between March 22 and April 4, those hospitals screened 215 pregnant women for SARS-CoV-2 (the virus that causes COVID-19), and 33 women, or 15%, tested positive. Of these who tested positive, 29 women — or nearly 14% — showed no symptoms."
Speaking of, This would help a lot of awful dark photos sent in to news sources.
> if you think about it you will realize that this appearance of "arbitrariness or choice" is an illusion.

I don't think that's the illusion. I think the illusion is that something as complex, for example, as "the airplane" has to be pigeonholed as either an invention or a discovery, instead of being a complicated process in which both invention and discovery were involved.

> Any story of invention can be re-cast as a story of discovery.

I think this depends on how far you are willing to stretch the meaning of the word "discovery".
I hear you. I do however use git but it's unrelated to deployment. I just upload master and overwrite everything.
I’m confused why some of these backgrounds are mirrored. You know that when you see your background in Zoom it’s only flipped for your benefit, right? It’s sent to others the normal way round...

But that sounds like a case where the attacker would have gained access to most relevant stuff anyway, and the difference in effect was mostly to the tune of $35k in costs (instead of spending resources on companies' own hardware)? While that's a big chunk for a start-up, it's not even one year of a developer salary.

While I am of the similar old school like you (I run my own mail server, web server, nextcloud, used to do ejabberd too...), I think it's more cost effective for smaller companies not to do it themselves, as long as they keep their own backups.

The difference is that when they self-host, they are more vulnerable to targeted attack (on average, for similar dollar investment), but if they host with SaaS providers, it's opportunistic attacks they should worry about more.
You point to one example (4chan) yet there are probably hundreds of thousands of counter-examples of usage of ORG domains.

There is no perfect solution of course, but generally speaking ORG domains have been used to signal that you are an organization vs. a corporation, and potentially a non-profit.

That said, just like in the real world, individuals are encouraged to do their research and confirm that one is what they claim to be (just like door-to-door charity workers) before engaging.
I once did the reverse karnaugh mapping on a set of expressions to minimize their complexity; the input set was 7 bits.

Specifically, I created an instruction mapping on a 7b opcode space such that the decode logic for the critical paths was short (eg, branch decode). It took multiple sheets of paper, a few tries, and a couple of days, but it wasn't too bad.
I guess I might have misinterpreted the goal. If the goal was to make the image look like it was daylight, then maybe whitewashing that light reflection was the correct choice. If the goal was to "see in the dark", then it seems like a very bad choice.

EDIT: Finally got the paper to load via the helpful wayback machine link provided in another thread. It looks like the goal was to simulate a long exposure with a short exposure. So whitewashing of "bright" areas in the original might be expected.

CAs generally issue certificates to websites for 1 or 2 years, but there isn't a fixed duration imposed by cryptography standards. Sometimes the certificates are rejected prematurely due to compromise, and there is a process for that called key revocation.

I am thinking you reading something more into what I wrote than the words on the screen.
A tangentially related question about these codeless GraphQL API/app generators while we're on this topic. I'd appreciate opnions on this one.

A while back I was building a read-heavy site where the most popular views are easily cachable -- think a scoreboard monitored by hundreds or thousands of people simultaneously, and updated every 30 seconds. The view, or data for the view should obviously be cached, so that thousands of people don't need to hit the database at the same time with the same query.

I looked into whether I could leverage Hasura for this (no particular reason, just heard raving reviews and wanted to give it a shot). Turns out Hasura always hits the database with every single request, and it seems there's no way to avoid this. Of course GraphQL doesn't lend itself well to caching either.

Are there any solutions to this sort of problem? Or was my use case fundamentally not suitable for Hasura or similar tools?
There are similar high infection rates from other semi-randomized samples.

> Between March 22 and April 4, 2020, a total of 215 pregnant women delivered infants at the New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center . All the women were screened on admission for symptoms of Covid-19. Four women (1.9%) had fever or other symptoms of Covid-19 on admission, and all 4 women tested positive for SARS-CoV-2 (Figure 1). Of the 211 women without symptoms, all were afebrile on admission. Nasopharyngeal swabs were obtained from 210 of the 211 women (99.5%) who did not have symptoms of Covid-19; of these women, 29 (13.7%) were positive for SARS-CoV-2. Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of Covid-19 at presentation.
Sepp Holzer's farm is amazing. I think however it's unlikely that he's truly able to grow citrus fruit at scale even using all of his near magical techniques. Where he is able to grow citrus fruit is taking advantage of very small micro climates with ponds buffering temperatures and acting to reflect evening sun along with perfect orientation etc.

I mean if he's having problems and spent hundred of hours trying to fix it, instead of giving up why not just try one of the mainstream distro and see if it works? There is a chance (however slim it is) that it'll work due to higher number of users exposing hardware support issues to the maintainers.

Super cool. This seems like it could be really good data to build some better visualizations.

Just playing with it now, but some quick feedback:

- Disable the lock screen while watching the visualization. I have to keep tapping it while music is playing.

- Is it possible to select the input source as the "speaker out" (or whatever ios calls it) rather than the microphone so only the music playing is analyzed rather than the microphone. My clicky keyboard is messing up the music visualization.

Nice work!

Fwiw, you don't need to prepend it; you can put it anywhere in the query
Another advantage of selling crippled high end products as low end is that they can sell defective hardware.

For example, if there is a bunch of cameras with defective GPS units, they can still be sold on the low end segment, where that feature is disabled.
There could be a meaningful distinction between exposure and infection. I would define the first as anyone who was exposed to the virus (or even just parts of the virus) and generated antibodies. The second would be an actual infection and presumably a sufficient antibody response to repel the virus and confer immunity to another infection. Really you can generate antibodies without even getting exposed to live virus, just like you can develop allergy to pollen or other foreign objects that enter your body. I would say only the second case is meaningful for public health. For that you need to look at how people do convalescent plasma. You need to test for specific antibodies that actually confer immunity.
There's also some data coming out of Wuhan around antibody testing. The methodology is not as well formed as the study in the OP but there is still value in the data.

> Wuhan’s Zhongnan Hospital found that 2.4% of its employees and 2% to 3% of recent patients and other visitors, including people tested before returning to work, had developed antibodies, according to senior doctors there.

Additional antibody testing is also underway in Wuhan.

I didn't dismiss philosophy.

I said that as soon as you fix some axioms (such as those of classical FOL), the conclusions are irrefutable. This is where mathematics begins. The question where those axioms come from or whether they are "true" are philosophical. The two disciplines are related, but separate.

Lots of mathematicians have different "foundational" beliefs from each other; some have studied or deeply thought about the philosophy, others may just speak to their intuition. However, this doesn't change the fact that they all come to the same conclusions from the same premises. E.g. a constructivist wouldn't be able to claim that a classical proof is "wrong", only that it's non-constructive and therefore unacceptable for some (philosophical or practical) reason; in fact non-constructive proofs can be seen as constructive proofs of some meaningless strings (e.g. the constructivist will maybe dispute the fact that there are discontinuous functions, but they will certainly accept the existence of a first-order derivation of the string representing "not all functions are continuous" from the axioms of set theory), the constructivist would just dispute that there is any meaning to these strings...
Swiftly Speaking
We don't have good GPUs that is as fast until 580 (or to some extents, the first Titan). Previous generations only about 2 to 5x faster depending on what types of CPU you compare against.

IMHO, credit should always go to Alex Krizhevsky for the rapid spread of deep learning. He has shown us it was possible. Even without Tensorflow and PyTorch, we will be fine with Caffe, torch, mxnet or Julia.
And centralization of decentralized entities isn't a question of if - it's a question of when.

Decentralization has so many downsides compared to centralization when things are going "right" that centralization has competitive advantages over decentralization.
I think they mean, the science is more rigorous because they have to deal with anti-vaxxers.
> Numbers don't inherently exist

How do we know that it is true?
> There is this thing in math called the "axiom of choice" which you can, quite literally, choose to accept or not.

No, there are these different mathematical structures: set theory with the axiom of choice, set theory with the negation of the axiom of choice, and set theory with neither. (More precisely, "Zermelo-Frankel set theory", since there are other set theories.) All of those structures were discovered. And, as I said, different humans invented different notations to describe these different structures.

Humans choose which of these structures to use for particular applications, yes. I don't think that process is either invention or discovery. Not everything humans do has to be an invention or a discovery.

Similar remarks apply to geometry.

"We recruited participants by placing targeted advertisements on Facebook aimed at residents of Santa Clara County..."

I wonder if these ads mentioned the purpose of the study, or if that information was only given out after initial contact (I don't know enough about IRB requirements here).

A concern is that this could cause a selection bias for people who suspected they had the virus. People may respond to such an ad out of curiosity ("I think I had the virus, so it would be good to know for sure") or obligation ("I'm pretty sure I had the virus, so I should help out with this study").

It wouldn't have to be a large selection bias, either. Of the 3,330 people they tested, they found only 50 who tested positive.

I would like to see a bit of a better method of sample selection before drawing any conclusions.
Tech is in the uncanny valley.

What makes this especially disturbing is that pupils are sticking out in almost all the examples.
The state of the art on path rendering, both academic approaches such as Random Access Vector Graphics (Hoppe and Nehab), Massively Parallel Vector Graphics (Ganacim et al) and more practical implementations such as Slug (Lengyel), Pathfinder (Walton) have advanced considerably beyond NV path rendering. I also hope to do considerably better - my approach is most similar to Pathfinder but with more of the expensive CPU operations moved to GPU.
There are times and places where electricity has a negative price, and potentially a carbon pricing scheme could subsidise taking it out of the air. But a big factor in this is the cost of the plant; nobody's going to spend £100m on a plant that runs 5% of the year. Hence the desire to simplify the process.

The US navy also has a use for this: at-sea refuelling of planes and other ships from the spare power from the nuclear aircraft carrier.
Truck driving doesn't change a great deal. Software development still changes on an annual basis. As such, it feels to me that certification would go out of date extremely quickly.
Show HN: I built an actual Chaos Monkey for Kubernetes
Add this to growing pile of evidence that this coronavirus is more widespread than most testing to date would suggest. How much more widespread still appears very unclear. There is a major ramping up of antibody testing happening right now, and multiple new tests being introduced, so we should have a better idea very soon.

But the takeaway should be that this is a good thing. Every unknown case we uncover decreases the overall rate of hospitalization and death, and potentially decreases the effective transmission rate (assuming most people who had the virus develop immunity and that the immunity lasts, which is also still unclear).
Another loss for Boeing on top of the 737MAX debacle and Covid-19. I would hate to be their CEO right now.
He was but really he had more of a commercial mindset that was against level playing fields and against free software. It didn't make him evil but not a role model either. Now that his imagine has changed and he is playing with medicine buying off the news he is more dangerous to everyone.

I made this comment the last time a serological testing study came out: they have 30 negative controls and claim 1.5% positives among their tests. So the number of controls is insufficient to rule out this being entirely false positives. You have to then rely on the test manufacturer's claims of false positives rates, which comes from 371 negative controls. They say:

> our estimates of specificity are 99.5% (95
CI 98.1-99.9%) and 100% (95 CI 90.5-100%)

Look at the those confidence intervals, even the narrower one (from the manufacturer's data)! The bottom is a four-fold increase in false positives, compared to the point-estimate, and is greater than the total positives they had in their finding.
Show HN: Uni Beta – a decision making platform for teams
Hey HN! - As you go into the weekend check out Uni (https://uni.fyi), we recently came out of closed beta and are excited to share what we’ve built to help remote teams involve the right people from their teams to make smart decisions!

We’re an early-stage spinout from Cornell Tech and we see decision making as a natural wedge to actualizing inclusion within companies. Since there are no go-to products out there which facilitate this process fully, decision makers often-times become overwhelmed and frustrated with including people in their decision process resulting in an exclusive culture.

Uni helps decision makers bring in their teams into private spaces where everyone can share, discuss, and build up the ideas needed to make smart decisions. Uni’s Momentum Engine also keeps track of when decisions need to be made and reaches out to people via Slack, email, or push notification to help engage the people needed to get to a smart decision.

With Uni you can ask questions like:

1. What are our goals for the next week / month / quarter?

2. What trends were hot this week?

3. What are questions, thoughts, or concerns we should talk about at the all hands?

Feedback is always welcome, we are particularly interested in how we can extend our integration support to make Uni fit into your existing work-stacks!

We also put together some starter templates to make things easy! https://uni.fyi/templates

Stay safe and have an awesome weekend!

Right, that's why people say the Chinese government's lies (and the WHO's acceptance of them) are at fault. The rest of the world certainly should have reacted sooner, ramping up PPE production and researching treatments and trying to slow it down. But the idea of complete containment, forming widespread green zones where the virus is not merely suppressed but eradicated, probably became impossible as early as February. (Some island or basically-island countries appear to be making it work, but it's not clear what their long-term plan is - are they just going to enact sakoku for the next 18 months?)
What is WeChat?
This has been my silly weekend lockdown project. Would be helpful if anyone is able to test it and give any feedback. Thanks!

If you're going to mention flu deaths please at least count covid-19 deaths using the same method.

> people died from the flu in the US and we didn't do anything more than make flu shots more available.

We have internationally coordinated campaigns of surveillance and data gathering. We have rapid vaccine development. We have global, regional, and local flu strategies. We have pandemic preparedness programmes. We put in place public health measures -- you may not have seen those but they're there.

> Moreover, while it's a morbid task, rational adults should be able to ask whether the costs we've paid dealing with this corona virus are worth it. At 758 deaths, and even 21 days later at 26,300 deaths

Do you know that you're undercounting covid-19 deaths? The number you quote is deaths in US hospitals. Many people die with covid-19 outside hospitals, mostly in care homes. This is partly because hospitals in some places are overwhelmed and they're triaging elderly frail people onto palliative pathways. And yet we still have people like you denying the reality by quoting statistics that you do not understand: covid-19 is causing massive excess mortality.
