Hello, at this point this question is hard to answer.

I've identified a lot of real customer profiles (as I call them) that can use the product and receive value.

Some of those are: e-commerces, marketers, affiliates, investors, SEO experts. If you are curious, you can read more about each of them on the homepage, in the "use cases" section.

I don't know which one of these customer profiles will benefit the most at this point. It's too soon, but time will tell.

Thank you for the comment!
Show HN: ScribbleX – Create some art with friends
For what it's worth, Germany is currently taking patients from Italy[1] and sending ventilators to Spain[2] to help them out. I think it just took some time to go from "scrambling to prepare" to cooperation between EU countries.

Hey HN,

we are Marten and Philipp, the makers behind ScribbleX – a social drawing game for iOS and Android. The idea for the app was born one lazy afternoon while playing a round of “Exquisite Corpse” with some friends. "Exquisite Corpse" is an old parlor game that was invented as creativity exercise by surrealists way back in the 1920s.

The game is simple. Take a piece of paper and divide it into three parts. Now, player 1 draws a face on the first part of the paper, folds it over and passes it to player 2. Player 2 then draws the body, folds it again and passes it to player 3. Player 3 draws the legs or feet on the third part of the paper. In the end, you unfold the paper and a funny creature reveals itself.

We thought that the game would be great on mobile but couldn’t find it anywhere. So we decided that it would make for a nice side project.

We originally released the app almost a year ago. Unfortunately, we only get to work on it at nights and on weekends so progress has been a bit slow. With the recent Covid-19 crisis, we thought it would be good opportunity to give the app a nice general overhaul and present it to a broader audience.

It’s completely free, so we would love to hear what you think!

I'm glad to see someone taking such a forward looking view in this crisis.

iterative development goes back much further.

The industrial revolution made iterative design possible because it made the time and effort of producing something far cheaper.
The weight of a bunch of DLLs, type information etc for chromium is actually pretty sizable. An electron app spins up 6 processes on average last time I checked, more sometimes. The v8 team has had to invest a lot into reducing bloat from per-process duplication of data and also found ways to minimize startup time.

The largest part being private doesn't mean saving 10-20mb per process is insignificant. With a few electron apps open I'm easily losing a few hundred megs to electron overhead and many machines don't have that much RAM, especially laptops.

Each electron app also needs its own copy of centralized services like the i/o process, where a single chrome instance can share that across all tabs. An OS-level PWA implementation could share it across all PWAs and electron apps too.
He could fed megalopolis of his time (with what they expected), and pay soldiers of empire of his time, shouldn't we adjust this as well?

* Feed New York for one year, grocery expenses $500/month [1]

8000000 * $500/month * 12 month = $48 billion

18000000 * $500/month * 12 month = $108 billion // metro area

* Pay US Army soldiers for a fifth of a year [2]

$140 billion / 5 = $28 billion

Who have enough to pay that?

Contemporary athletes, even Michael Jordan ($2.1 billion [3]) absolutely can't.

But Bill Gates ($106 billion [4]) can! As well as Jeff Bezos ($114 billion).

Thank you for the compliment ^_^ I'm glad you found the post helpful.

This isn't a typo, actually. If you look at the documentation of the BSRR register (which is screenshotted in the blog post), it says of BRy:

> These bits are write-only [...] [Setting to 1] Resets the corresponding ODRx bit

So setting BR8 in the BSRR clears the ORD8 bit in the output data register. Because our LED is active low, this turns the LED on.

The indirection can make this a little confusing, I hope this cleans it up!

They don't. Very few people start from nothing and end up "very successful" (by which I take it you mean being rich and influential). You're just forgetting to divide their number by the number of people who start from nothing overall, which is Billions.
> CTR mode, which is what was supposedly "recommended" here

Where are you getting this recommendation? Who recommended it - to Zoom? And when?

> You know more about the codec situation here than I do. So, you tell me! What should I be looking at?

If you're prepared to be at least slightly interested in problems even if ECB only contributes rather than blowing them wide open, then maybe you should look at H.264 I-frames first.

An I-frame stands on its own. For example the WebP image format is essentially just one I-frame from VP8. If the scene is literally unchanged from one I-frame to the next, all the exact same image data must be re-encoded, and logically (if the codec is at all efficient) that means the same bytes.

[ If you just don't use I-frames then all loss becomes unrecoverable and people will stop saying your product "Just works". In products like a DVD or Netflix I-frames are needed to make it "seekable". This is obviously not a necessity in a video conference, but the ability to handle network glitches and to add/ remove participants seamlessly is a requirement ]

So with ECB for I-frames clearly we can tell if nothing changed. Maybe an artificially lit meeting room with nobody in it, a desk left unmanned. Or a screen share left showing an unchanging desktop. Is that a "useful" thing for eavesdroppers to learn? Do you think Zoom users would be surprised that eavesdroppers can tell their colleagues took a coffee break?

But because codecs like H.264 are oriented around square blocks I suspect we can do better. They're not deliberately trying to have these blocks encode to exactly 16 bytes and so mostly they won't, but of course one chance in 16 isn't nothing and we get to try every I-frame. Probably not to the point of getting a blocky outline of a moving person on a stream (which is sad because I'm pretty sure that, like the Penguin, would make the point viscerally) but enough to have some idea which parts of a scene (or a slide deck) are changing.

I usually try to stay away, but I'll bite this time. I have no affiliation with Google, don't own their stock nor ever have, but these kind of responses bug me.

Working in data science I keep thinking about how I would solve a particular problem. Regarding real-time traffic: how would you solve something like this? Clearly one has to have a lot of anonymized data one can trust. Now the question is how to get these data. Google is building it's business on providing a useful service, like gmaps, for free and on using the data from the users of this service in aggregate to sell useful information to businesses that require these data for whatever they are working on, like the company in the article. Google is very transparent about how they use your data when you use their service and they seem to try to do their best to anonymize these data, e.g. you hardly ever get the access to even anonymous data outside of Google, but rather to the information computed from these data. So I see no objective reason for being so angry. What am I missing here? In the end, if you ever want a service like "ETA at destination" someone will need to acquire the data anyway, right?
I don’t see Canada on the list which makes me sad eh.
> Bug bounty programs are not supposed to replace you other security activities, but it's a way for you to have additional source of vulnerabilities.

Exactly the way we position our own Bug Bounty Program. Where the pentesters can be hired to also confirm things done well, the hunters are only paid for failures they found.

In our case there is an added bonus with the Bug Bounty Program: we've come to REALLY apriciate the technical level of reports. Since they only get paid for triagable findings, the details we get reported are so much better then what we used to get from our pentesters. Of course we now require the same quality of reporting from them.

What also helps is that the pentesters are motivated more to deliver higher quality findings since they are aware the service will enter the Bug Bounty Program after their findings are resolved.

Again, BBP should NOT replace your other security activities, they are an additional source with possible unforeseen benefits.

VS Code on desktop can run arbitrary processes, that’s how it can, say, have in integrated terminal. You cannot even remotely do that on iPad. Executing Python and JavaScript in a pre-compiled runtime environment[0], like Pythonista and Play.js do, is an entirely different approach and results in completely different products, ones like... Play.js and Pythonista.

The reason that VS Code is not on iPad is 100%, top to bottom that the framework and App Store restrictions prevent running arbitrary processes.

[0]: VS Code can run any binary on your system, iPad apps can only run binaries that they are compiled with. This distinction is why almost no existing development tools can be ported to iPad, almost all development tools are built on interacting with many binaries that the tool was not necessarily compiled with.

Flutter Tutorial: Reverse Geocoding and Location
(sidenote: “snabb” is Swedish for “fast”)
Hi Peter, I’m 4th generation of (South) Korean Japanese who traveled to North Korea in 2018. My application for B-2 visa was filed last August and after “administrative processing” status, it turned out to be “refused” last week. While I intended to use ESTA in the beginning, I was forced to switch to B-2 visa following Trump’s decision to disqualify ESTA for those who have traveled to North Korea since 2011.

Since my job requires me to interact with our clients based in the US, losing the ability to see them would put me in a horrible position.

I have contacted the embassy multiple times to ask if there were any additional documents to submit, but I was only told to wait for an update online.

What do you think I can do to continue the appeals process?
Is there a trend where those who have been to North Korea are all rejected?

> pretty much the only thing that matters is how you compare purchasing power and adjust for inflation

Or just compare it to the average salary at the time

Is there an athlete today that could pay for the entire Roman army (80 thousand people more or less, their salary, food, houses, equipment) for a year?

The 1,000$/year expenses on staple food is entirely made up, Roman food supply wasn't based on agriculture, at the dawn of Rome it was vegetables, catch of the day and the occasional meat bought at the market

When Rome became an empire the food started coming from all over the place as a tribute to the empire, so to establish how much it costs you have to factor in military expenditure and the cost of the political structure to sustain the logistic

Romans in fact rarely ate at home, they usually went to tabernas where they could buy their meals

Supplies were taken from the provinces and brought to Rome, that's why they also built roadways, harbours and other facilities to improve moving armies and good throughout the empire ("all roads lead to Rome" was born from that)

Now you have a better idea how much 5 times a local governor means. It means 5 times the amount of goods and troops a local governor could control.

It's like saying that an athlete today earned 5 times the GDP of an US State.
I think it's a bad idea for a database to start implementing third-part vendor related features.

That's the type of feature that should be implemented as a plugin.
First and foremost, we give our users the ability to monitor a keyword/topic over time. As a user, you can receive daily, weekly and monthly email alerts.

Secondly, you can search a keyword/topic in any country and what you search stays private to you so that you can build your own private library of trends.

Thirdly, each trend has so many related topics that we find by querying Google, Amazon, YouTube, etc that you can dive into.

And finally, we have a beta feature where the tool forecasts how a trend will likely perform in the next 6 months.

Btw, I'm pretty sure that I originally launched this tool before them. I'm just revamping it now =)

In outbreak areas, total morbidity increases by multiples to magnitudes during the peak (despite enormous, historic measures of containment). Areas with processions of army trucks full of bodies, or the defense department bringing in refrigeration trucks.

"But what about the co-morbidity?". People don't die "of" COVID-19. They have heart failure, kidney failure, or other triggers of death because COVID-19 pushes their body to the limit. Pointing to resources that claim that "only" some small percentage actually died of COVID-19 is pure ignorance, because then the declaring doctor was simply being efficient because if they truly looked in there would be another triggered cause of death. Just as no one died of "AIDS", they died of things like Kaposi sarcoma, but if someone said "see, it wasn't AIDS at all" they would be laughed out of the room.

The majority of deaths are people who are health compromised in some other way (not all deaths, and there have been an abundant number of completely healthy people who have perished), but that is known by everyone and is not news, nor does it diminish the tragedy.

"no statistical extrapolation"

This is the most interesting, and ridiculous, claim of all. Enormous statistical measures and extrapolations are being done daily...that's how we are where we are. What is this meaningless claim even trying to say, other than that you, easytiger, know more than every health authority.
The two big metrics I would use to measure inflation

* How many acres of average quality land could you buy?

* How many hours of average skill labor could you buy?

Maybe we should also have one taking improved efficiency into account

* How much food could you buy?

This is a 20 minute interview with an ICU doctor in Wales.

He talks about the pressures on intensive care, about the reduction in capacity and how they'll have to overflow to other areas quite soon; he talks about the difference in intensive care for covid-19 patients and other patients (all staff are in full PPE all the time, which isn't normal, and the covid-19 patients in ICU are more ill than other patients in ICU); he talks about good morale in the circumstance.

He also talks about the unexpected impact on younger patients -- all their ICU patients are in their 50s or younger, and do not have comormid conditions.

He speaks about the distress of people not being able to have visitors, and of having to think about how family members can be with their loved ones as those people die.

He talks about the mechanism of death, which includes respiratory failure, multi-organ failure, but he says the main cause is myocarditis.

He speaks about his experience of having and recovering from covid-19.

It's a great interview and well worth watching.

The UK went into covid-19 with fewer doctors, nurses, beds, ICU beds, per 100,000 population than most other EU countries.

Yes, there have been some trials in avian flu at least, and a few attempts in original SARS and MERS, with success.

The problem here is the mediocre quality of evidence. Mostly limited sizes, but also lacking randomization.

Also rabies, tetanus and hepatitis B and C sera are available. Those have high quality evidence for working.
To me your comment sounds unnecessarily rude.

I guess you are reacting to private smug conversations with people who eulogize ML but are clueless about what they are talking about. Usually the amount of conviction they add to their comments and advice is inversely proportional to their knowledge. I am tired of those too, to the point of being allergic in spite of being an ML practitioner myself.

The parent comment could have been worded better but I think you will agree that there is scope for using ML or statistical modeling of some kind to optimize the use case both in API cost and accuracy. Making some minimal number of API calls would very likely be part of such a system.
Thanks I'll check it out, it sounds kinda like what I'm looking for overall

I think you mean the OSI (Open Systems Interconnect) stack, and it "came out" much earlier than 2006. I remember working with it myself in the early 90s. It's also inaccurate to say it was a clone of TCP/IP since many parts of that beyond simple packet formats (e.g. congestion control and routing) were still very much in flux at that time. Innovations were being made on both sides, and often transferred between the two. This was a time when DECnet and NetWare were still in use, and they also had their own heritage separate from TCP/IP. IETF was not the origin of every networking thought ever.

But you're right that this is mostly about telecom folks not getting over their loss in the circuit-switched vs. packet-switched war, and that chewing off limbs would be preferable to working with ITU-specific standards again. ;)
