This is exactly what I needed and was thinking about building a similar app. But to be really useful and automated, there's a bit long way I'm afraid. The biggest deal breaker is the time spend for the data entry and updates, leaving a pen-and-paper / notes solution still the most easy to use and just visiting local groceries and shops. I was collecting receipts and playing a bit with scanning of these, but the amount of noise in the data and inconsistencies between shops were a bit pushing away (unless you want to dedicate time cleaning the data and training own tailored information extraction models).

One of the options to solve the data entry could be:
- good quality automatic scanning of receipts (not only individual barcodes) from shops using OCR possibly supported with image recognition for double-checking (can happen that products will be mis-labelled or without quantities, etc)
- when ordering on-line, the receipt should be available, so should be also much easier
Yet, not always one will have a meaningful receipt available...

Solved the data entry and being able to predict own's supply needs would be also great to have a up-to date management of the inventory. Here are even more challenges on the tracking of the available goods at home, where these are and how many items (and in what state, expiration date, etc) would require most probably implementing different solutions from IoT (connected cameras, sensors, etc.).

Then, having a connected home with own groceries supplies under control, one can then automate further the shopping process with feeding-back the information about own's demand to on-line groceries one is subscribed to. This can enable customer subscription plans, and for retailer keeping a possible continuous flow of goods. This could be really really useful especially for upcoming months, when it seems like we are expected to spend a bit more time at home rather than usual, hopefully not fighting in the local shops for the last rolls of the new white paper gold.
You really think that the freedom to organize a neonazi cell is more important than the freedom not to be robbed at gun point by the police?
Cool product but... This is wayyy too much much. To need an ERP for this problem? And to deal with self-hosting, teaching everyone how to use it.

> Where are you getting this 0.4% number from? Korea is testing extensively, so CFR is very close to IFR, and CFR is above 1%.

That's not how CFR works, and I was referring to this data [1] which showed folks under 30 with a CFR of 0%, 30-50 at 0.1% and 50-59 at 0.4%, and a total of around 0.69% at the time the data was published.

ZeroTier original (and still main) author here. Objectively speaking another difference is the ACL scheme which seems perhaps less powerful than our own rules engine but easier to use. The ACLs are closer to intents while ZT rules require some TCP/IP knowledge (like raw iptables or pf).

We have plans to address this ourselves more with a higher level UI to build rules from intents and common patterns. Also have more auth integration planned, but the list is long.
If only we had a system for 'fingerprinting' individuals, and digitizing the results into a searchable 'database'
UK supermarket baguettes are a poor approximation of continental Europe's (I suppose most of my experience is of France's).

Actually, Waitrose's baguette - as opposed to its 'flute' or 'French stick' - is not bad. Not as good, but not bad. The cheaper flutes and sticks (which seem to be all that other places sell) are just.. completely different.

I've never had a baguette with a nice crispy outside that results in flakes all over the breakfast table, and a soft, fluffy, inside like those so prevalent in France though.

While I'm at it - tomatoes! Tomatoes are so much nicer in France too.

P.S.: If you practice time-restricted eating (intermittent fasting), it's better to skip dinner than to skip breakfast.
Any virologists here? Is it possible that we may have a grave future where a virus emerges with R0 value of 6-7 (such as measles virus), long incubation period (10 days, contagious on 2nd day) and a death rate of 50-100% (such as Ebola)?

A virus with the combination of all of the aforementioned properties would guarantee complete extinction of humans (or we get very close to it). Should we consider ourselves lucky?

Edit: my intent wasn't to incite panic, but to learn about the virology, molecular biology and the physics of transmission.
Lecturer is the guy who started the controversy about terminal ads in npm.
Bill called this years ago. He's also incidentally done more to save lives from disease than possibly any other living human, having prevented millions of deaths by malaria and other illnesses purely because he wanted to.

There is lots of other information out there from doctors and scientists. We needed that and we got that. The point here is to get Bill's unique and valuable high-level perspective.

Nobody is 'waiting with bated breath for the pronouncements of the wealthy'; this is ridiculous and I think you'll know it if you read it back with even the slightest attempt to look at the situation neutrally.
I have found satisfaction at least for now in going in the other direction - what can I do with a locked down computer that has absolutely no software installation authorized and only has the standard software for any non-technical employee. In other words, everything that can't be done in that environment is now "herding goats" to me. Sometimes I am tempted to try to get developer-type privileges, but I've resisted so far.
I'm not a doctor but if I'm reading it correctly they did a study with 16 normal weight males and found that when eating in the morning their blood glucose and insulin concentrations[1] were lower after breakfast compared to dinner regardless of calorie consumption.

So eat more in the morning and less at night.

Python is not Java. It does not enforce type annotations by design. It's not a weakness.
Agreed that this would have to be a smart vision system that can scan the barcode, and maybe the shelves are attached to a scale to determine weight of items as they are placed back in. With that information you could determine size of a jar of mayo along with its current weight to estimate amount of mayo remaining.

Meats and vegetables would still be a challenge though, but perhaps object recognition could help with that.

Fridges are already overpriced for what even the fancy ones can offer, I imagine we're not there yet to incorporate multi-camera vision systems with beefy AI processors at commodity prices yet.
Dividends also make prices go up. They're just priced in in advance. Look it up.
Actually signal processing is already used for most machine learning of audio signals, including speech recognition. The reason is that ML algorithms, including deep learning has a hard time learning the information you can get from a discrete Fourier transform.

Audio data in time domain are just too noisy for most machine learning, and doing some signal processing as a preprocessor step often helps a lot.

Here it seems like he works with non-audio data, where this is less common.
I'd wager that theres a big overlap of antivaxxers and people who think the virus is a hoax / media sensationalism
I warned you a week ago we would "waste of resources" and here we are:

"Health officials are struggling with a complicated message — more people can get tested, but those with mild symptoms should stay home and practice social distancing. Some go so far as to warn that widespread testing at this point could threaten the U.S. response by burning through precious supplies just as a tidal wave of sick people descend on the system — a message at odds with administration announcements that millions of test kits are finally becoming available."

I unsubscribed, when I learned they don't deliver the proclaimed resolution to Linux browsers. How about you warn me about that beforehand? They know my Browser's fingerprint. That's just a scam.
Good idea in theory, not so much in practice, especially over longer periods of time. First, people are fallible and many of them who don’t know if they have it or not, may not take it seriously. Having a positive test (even if asymptomatic right now) would put them in a different mindset. The ability of quickly confirm recovery would put the people in critical roles back to their occupation. Medical professionals, police, truck drivers, water treatment plant workers, utility workers are all going to get sick in droves and it is not going to be pretty.
No it's not very hepatotoxic, on the contrary.

Whole world is waiting for blueprints. There are many many industrial 3D printers out there. Even with fraction of them companies could print all the needed ventilators worldwide. There is no worldwide authority, that can provide these blueprints. And that’s imho the biggest problem today.

Edit: It might contain electronics, but there is pandemic, not global war, so printed circuit manufacturing capacity is still there. Some modules with microprocessor are widely available worldwide and the design can be constrained using such module and 2 layer carrier printed circuit board. Machines to build these are available at better maker spaces. Pick and place machines are also there. So basically my timeline would as follows: order parts on Digikey and mouser today, go to maker space, start engraving printed circuit boards and launch 3D printers. On Monday or Tuesday digikey ships the parts. Maybe it will arrive on Wednesday, shipping companies are busy right now. On Wednesday I would launch pick and place machine and produce first batch of boards and next day I would start assembling manually the devices. On next weekend I would have probably 10 units to start tests. That’s working alone. With other tech savvy individuals output would be orders of magnitude higher. And this is not theory, in my previous workplace team of 8 blue collar workers was shipping 2000 units of comparable machinery per year.
So exactly what do graduates do with a degree of it isn’t to earn a living? Money comes from producing products that people want? All of the great “research divisions” that couldn’t productize died in favor of companies like Apple who focused research on products that people wanted.

Jobs famously killed Apple’s Advanced Technology Group that brought the world things like PowerTalk, OpenDoc, and QuickDraw GX. Microsoft’s Research division hasn’t done much better. I’ve already mentioned that Google has wasted untold millions on
products that no one wanted.

But the bigger question is are the degrees actually preparing students for the real world outside of Silicon Valley where companies actually want people who can add business value? Will it prepare people to compete for jobs against cheaper foreign labor where they are more focused on actual “occupational training”?

Sure, you could also replace the indentation with open and close brackets, replace some keywords and change the standard lib to be like Java.

Or you could use Java which it seems is what you wanted to use in the first place and leave Python alone.

The thing is multi-channel guest users are counted as your internal users for billing purposes. If you work with lot of clients (accounting firms, realtors) it is not really affordable. Also, in scenarios where the clients have their own workspace than they need to switch the workspace and then access the channel.
Everyone is focusing on the touchscreen, because those are easy to point a finger at (pun intended). In fact, this study confirmed what we already knew from previous research: even hands-free phone interfaces are terrible for driving.

The best hands-free reaction time in this study was still more than twice as bad as the effect from alcohol.

You simply can't operate a motor vehicle and a computing/communications device at the same time without seriously affecting your competency at both. Humans aren't built for that kind of multitasking. I don't anticipate any new technology which might change that.

| "Eat breakfast like a king, lunch like a prince, and dinner like a pauper."

Sadly this is the exact opposite of how I prefer to eat :/

Excluding the occasional Saturday mornings when I enjoy making a big breakfast of waffles, pouched eggs, etc for family/friends. Those are great, but for the most part mornings I’m ready to get on with the day and don’t want to spend time over a stove.
Ask HN: Has the virus changed your scepticism towards Starlink?
I wrote something like this. It used the bytecode, simulating types on the stack.

Functions with annotations had to be called with compatible types, functions without annotations were symbolically executed for each call site. Constructors were special cased so that the object attributes were set up correctly. Types for a stack slot or local could diverge and be narrowed depending on the path through the program.

The amount of metaprogramming used in practice in python made using it for real programs feel insurmountable. Also, I'm pretty sure performance would have been a problem beyond the toy programs I got it working on. But it was a fun exercise.

I'll have to dig up that code
Intermittent fasting has never been about specific times of eating. There are a number of versions, eat two days, fast for one, eat in the day, fast in the evening etc, but the idea is in the name, not the times. This research is interesting insight but it doesn't conflict with the core principle behind intermittent fasting in any way.
Thanks for sharing, Stefan. Lots to be proud of in what Starsky achieved, and factors outside your control at work at the end.

That's not a realistic risk unless you have some rare medical condition or are doping with a PED like EPO.
My CS degree if anything gave me a solid understanding of the line between problems you can solve with a computer, and the ones where you could throw technology at it, but you'll inevitably create more problems than you'll solve, because the real problem is a socio-political one.

It also gave me the framework of understanding to be able to reason about what is actually going on, and how. Being fluent in the major abstractions of a computer system allows you to more easily skip around between working in different real world contexts without getting flummoxed at your lack of knowledge on how that particular field does things. You know and can recognize the problems that you can best solve with a computer; so you just go ahead and fill the niche when necessary, and try to avoid the politics if you can/value your sanity/conscience.
If modern harware is going to be used, wouldn't a FPGA be a good way to replace the TTL devices thus lowering chip count?
Cellphones with voice assistants are already in general public use, even if you don't have one. So if general public use is enough to justify warrantless surveillance, we're already there.
not so much in practice, especially over longer periods of time.

Everything I've read suggests that older, densely populated cultures pretty universally have adopted bowing over shaking hands, eat spicier foods, etc.

My belief is that over longer periods of time, cultural change is a much more reliable and effective means to combat disease.

Ask HN: How do I sort roadmap tasks that don’t have a clear return value?
I’ve been sorting my product roadmap by impact vs complexity. But one barrier I keep facing is that I don’t know what kind of impact a task will yield. So for example, feature XYZ is on my roadmap but i’m not sure how to sort it because I’m not sure how valuable feature XYZ really is to my users. I have some data to form a hypothesis but not enough to be confident in estimating it’s impact.

How do I sort roadmap tasks that don’t have a clear return value?
Apple has always been more content with letting CPUs throttle themselves rather than cooling them properly or using processors that can't be effectively cooler in their physical design.

That said compared to other notebooks, MacBooks in similar tiers tend to benchmark quite well regardless of the thermal throttling.
Just a money grab by a special interest group - folks in the payment industry. Everyone is trying to figure out how to get their fingers on the $1 trillion that the Fed is handing out. This is saying, the SBA can't give out the money fast! Trust us acquirers/processors to do so! Give us the money and responsibility instead!

> When china went aggressive on the virus people looked at it as draconian measures because of the ideological lens, not looking further to see the measures were absolutely necessary by scientific fact.

None of this would have been necessary if the doctors reporting the Wuhan virus weren’t killed for presenting bad news. There’s clear evidence that the Chinese waited far too long to start acting and alerting others. Also there’s absolutely no reason to believe the Chinese are reporting accurate numbers.

The ideology that’s dangerous is authoritarian government. It happened in Chernobyl and it’s been repeated time and again with China and their respiratory illnesses from easily preventable sources.
WHO?

Every ventilator manufactured can provide blue prints of their old designs. There has to be old design without microcontrollers that could be made in most machine workshops around the world. I guess a modern design would be to complicated to outsource to random machine shops with all the special electronics.

It's a lot less yeast than I usually use, but I also only let it rise for an hour or two, not overnight, so I suppose that accounts for it. Assuming for simplicity's sake that rising & proving time is directly proportional to yeast quantity; if you had a limitless supply of both yeast and time, would you suggest less yeast and longer rise, for better bread?
Why would a virus effect my opinion of starlink?
So could an asteroid impact, or Yellowstone volcano erruption, or thermonuclear war. The question is how likely is it.

On the other hand, this is sort of a once in a lifetime (possibly once in an era) event and the reforms that would have made this easier to deal with aren't necessarily good for "regular" conditions...

Much like people's sudden views on UBI, especially those claiming that the upcoming stimulus is somehow proof that we need UBI or that it works - we're in a national emergency where hundreds of millions of livelihoods are threatened, any experiment we do now won't necessarily translate back to peacetime life.
