Proof: bring up removing time zones, such that there is only one time zone.

The responses are comical, even here on HN, such as not being able to wake up or not knowing when morning is or when meals are. Let’s not forget that time zones are a human invention less than 200 years old.
Perhaps to some extent, but I think the larger demand is for remote-education platforms, rather than educational content.

The shortcomings of platforms such as Google Classroom, SeeSaw, etc. are being laid bare both from the side of the educators and the side of the students.

I think we may see a huge opportunity for a new remote learning ed-tech platform to really run away with things in the near future.
There are no universal sources. Each source should be viewed with skepticism. That said, I have found small discords to be pretty good for PC hardware/tech related recommendation. Reddit on the other hand seemed a bit terrible at times with outdated or overly fishy marketing power speaking instead of the consumer.
Yes and no. They have a fake review problem, for sure. But it's usually fairly obvious which reviews are fake and which are not. And Amazon reviews have something I don't really see anywhere else -- pictures. That's a feature I really like.
I’ve been impressed by what I’ve heard about Walmart. They apparently won’t even use a SaaS tool if it’s hosted on Amazon.
It feels like some foods have fervent followings despite contributing to things like heart disease. It's a good example of how humans get thrown off when dealing with decades long timespans of bad choices that add up, except with food we all have to eat.

I recall that when processed meats including bacon were classified as carcinogens, people basically said "screw that, it's bacon for crying out loud." I'm not sure to what extent they were joking. I personally avoid all processed meats, but to me the public sentiment over some unhealthy foods is in stark contrast to public sentiment over smoking or alcoholism.

One time I searched something to the effect of "why are potato chips unhealthy" and got back a general sentiment of "well, they're not that bad for you, as long as it's only once in a while." I feel like with this attitude it adds up over time though. It's probably not possible to pin down exactly what foods caused a heart attack, as opposed to being able to more clearly associate lung cancer with a smoking addiction.

With smoking it provides no real benefit except lessening the craving for another smoke. With unhealthy foods everyone has to eat, so maybe you'd be more forgiven for eating them than throwing away your health on something not essential to survival. Fancy ice cream parlors are the norm, and nobody is going to lobby politicians to close them down in the name of public health. It's just ice cream, served by people working out of food trucks trying to make a living. The most they do is insitute soda taxes. God forbid soda itself is banned.

Is there an illustration on how foods like potato chips affect health long-term? Something like the study that estimates every cigarette takes eleven minutes off your lifespan. There are a lot of different foods to cover though. I feel like if there was data stating every potato chip took X seconds off my lifespan it would be easier to deny myself from buying them by looking through the items at the supermarket and being able to think "17 minutes, 22 minutes."

When I think of someone beginning to smoke I imagine them being told "you're going down a path that will almost certainly kill you down the line." When I imagine someone being a regular at an artisan donut shop I imagine people asking them how the taste was.
Even with food stamps food can become a commodity and be traded. It's generally a good idea to keep it need based IMO.
That was specifically about the Amazon marketplace, not AWS.
1. Making the defaults different between D and betterC would result in an impedance mismatch that would cause more trouble than it is worth.

2. I think you're referring to autodecode. There is an effort ongoing to extricate us from that, but it's difficult while maintaining backwards compatibility.

3. That's right. You'll have to use C threads.
I suspect Oracle is giving good deals as nobody ever considers them as a cloud provider, so they need to gain market share to stay relevant. They wouldn’t be in the top 10 lists of ones I would think of.

How many here even knew they had a cloud you could use?
Ironically John Deere's experience was much better than many competitors, or at least it was for a very long time. Some competitors' cabs looked like the cockpit of a soviet era fighter jet, with everything controlled by a huge array of toggle switches.
I do consider them serious, I just don't believe that Amazon cares at all. I run into scam shops on the German amazon site all the time, they don't get removed, and they are trivial to identify, so much so that you can generate a very good list for manual screening with a simple regex on the description. Amazon does not remove them. Amazon does not care. But I bet that Amazon would pretend to care and remove them if I could make noise on social media and shame them for allowing scams to happen on their marketplace.

> Freezing funds for 30 or 60 days is an effective fraud prevention tactic.

It's also an effective tactic to ruin companies. Amazon should pay a hefty sum for any false positives, they currently have little to no incentive to a) make their automated systems work well ("just block everyone that looks kinda suspicious, the ones with lawyers and enough money will get our attention") b) actually have a process in place to check their automatic decisions.
We were already using Webpack + babel. Adding transpilation there is fairly inexpensive (done by babel, without type checking).

Type checking did roughly double our build time. Even then, we do run type checking during builds because we prefer the added safety even with this extra time.

Developers run with an incremental checking watcher. It does add a significant tax, and takes a few seconds after saving in some cases (3-4). We would love that delay to go away, but it is a cost we are more than willing to bear if the alternative is not having type checking at all.
Java licensing?
Author here. Thanks for posting - happy to answer questions. I wrote this because I've been handed accounts like this before and it felt like there was no clear set of steps for simultaneously securing the account while not causing production systems to implode.
Oh no, I totally have the same question. I just wanted to make it clear that GCP was in the running since that was in your comment.

But yea, I don't get it either. I'd be curious to know why.

Great subject, great panelists, thanks!
Your premise is wrong: there is nothing unethical about closed-source software. In 99% of the cases users want great software, great customer support and don't care about the source. If they really do, they can often sign an NDA and buy it. And that's fair. Free market doesn't need a pseudo-ethical middle-man.

AssemblyScript would certainly do worse at #2, and possibly also at #1. To be translate to Wasm or from Wasm lead to different optimal designs, see for example how these two systems deal with loads and stores.
What does them "building their own encoder" instead of using someone else's encoder have to do with whether they do encoding using AWS's managed services or not?
The Fed can't really gain or lose money, as they create or destroy it at will. They're loaning with much lower interest than would be available on the open market, which is a direct subsidy.
Share your files up to 1 year without login or registration
Hi all, as SendGB, We launched a new service for file transfer. SendGB is file transfer service up to 5 GB without registration. There is no download limit. Files are automatically deleted after 7 days.But we have new service for keep files longer without registration. The new feature name is SendGB Extend. User can store files up to 1 year for €1,99. No sign up required. This is best part of the new feature. People do not like registration. Also keeping files up to 5GB for one year is very cheap. So i would like to hear your comments. Thanks
"The idea that children should study at home during the school closure is ludicrous"

This sounds like a cultural failing, not some law of nature.
You CAN'T preserve jobs, given the economic catastrophe that is occurring. Demand for many products and services have fallen off a cliff. Air travel is but one example. It's not like demand is going to recover overnight for the airline industry. It will take many years to recover. They will have to pare back flights and they will likely have to consolidate carriers in order to remain profitable.

Propping up zombie companies does nobody any good. It just leads to capital destruction.
They exercise monopoly power, by the law that makes them a monopoly.

Getting the JD to enforce monopoly laws is a whole other problem
Probably less than that. The reason it's so popular is that it's easy to install, requires no sign up...and you can record the meeting. Skype, Teams, Hangouts, Slack, etc all have difficult processes to join a meeting (or signup/signin/install programs to get to it.) I honestly think that is why Zoom has succeeded. Then of course there are the caps on meeting space, but I don't think that is the main reason for its success. Almost all boils down to the amount of friction to actually get into something. Microsoft, IMO is the one that really bungled this. They should be dominating the space. They should just roll out something called "Teams Meet" that is effectively Zoom, where people can join from Teams (you're signed in) or a small program that requires no signup/sign in. Doesn't take a genius to figure out the appeal.
Frank Ramsey – The Man Who Thought Too Fast
Users flagged it. We can only guess why users flag things, but I suppose the sensationalism of the material, the high charge in the title, and the poor quality of the thread were factors. The thread also set off the HN flamewar detector.

I've turned off the flags for now and replaced the title with a less sensational subheading in the hope that that might support more substantive discussion, though it probably won't. (Edit: well maybe it is.)
The issue here is that grammatical gender is not useful information when reasoning about the semantics of some sentence. Toothpaste in German is grammatically female, that's not a reason for an ML system to make feminine assumptions about toothpaste after it combs through data, it has nothing to do with progressive values, it's that the ML system cannot distinguish between a spurious correlation and actual meaning. Today many more medical graduates are women, this will change the ratio in the future and the inference from grammatical gender will be wrong. We should be able to tell an intelligent system from the get-go to ignore something we know to be spurious rather than fiddling around with the data.

And it's not strange at all to demand of an automated system that it behaves exactly the way we want it to behave. It is not human, it has to be more precise because it is rolled out at scale and it needs to do what we tell it to do. When we use industrial machinery in manufacturing we don't go "ah well humans are only precise down to a centimetre, guess we'll let it slide". An automated car trained on speeding drivers must not learn to speed. Automated systems are faster than humans, so errors compound, which requires more precision on part of a machine. If a ML system accidentally learns that ignoring someone wearing a green shirt is okay, and that is rolled out to a million cars, you don't have an accident but a big disaster.

We need a way to interface with ML systems in ways that let us put precise limits on when it makes inferences from data, why it made those inferences and when to follow logical rules, and when to dispose of certain data.
Thank goodness the title mentions it is Softbank backed, otherwise I would have missed some good Softbank bashing.
Look, human nature is to actually amass wealth without creating value. We are lucky we live in a society where value creation and wealth acquisition are at least tangentially related.

The problem in my opinion is not that a single person gets so much wealth, but rather what they receive the wealth for. Amazon just made life easier for the masses to consume goods. IMO someone like Einstein deserves a lot more money and someone like Bezos less. The people inventing the actual science that then enables something like Amazon don't really get compensated -- and perhaps they should.
Agreed, I think the main lesson from this topic is that decimal numbers are a pain. Stick to integers & symbolic operations. You can spit out a decimal approximation at the end

Computers agree: never trust precision to floats
The user experience is a lot better than it was a few years ago but you are correct, it's a lot of screens. There are two screens for the tractor itself. The lower screen above throttle, displays and controls tractor related stuff. The screen above does GPS guidance and mapping (automatic steering). There is a screen from the planter tool. That does mapping as well and probably does seed (population) rate control. The small blue screen I think is for the fertilizer controller (separate system and manufacturer again). I guess the screen all the way to the right is also for the planting tool. Maybe monitors the tanks that store the seed and other planter properties. I'm not familiar with the planter she is using.

They have integrated some things over the past few years (ISOBUS is the standard communication protocol for integrating). There is a lot more integration that could be done but it requires a lot of cooperation between companies. Also, the tractor is a multi-purpose tool and in this case is being used for a very specific job. So, many of the screens apply only for the job she is doing.
I recently made this realization and that eBay is actually better. eBay doesn't want 30% of the sale. I can order one item at a time prices are generally lower and, imo quality and risk are the same.
You can bake it again, as I understand it. It's obvious fairly quickly if it's still shedding...
For me the most disappointing thing is the licence: they all use the NC clause which makes the licence non-free, and thus these images can’t be uploaded on Wikimedia Commons.

Having a .torrent or a batch download mechanism is just a technical issue, which can be solved.
I managed a $60M/yr amazon business and these kind of issues would happen on a monthly basis.

We were on Vendor Central so we had a dedicated rep. He would avoid helping us however, and use the opportunity to force us to renegotiate our rates (so Amazon could have more margin). Then the issue would disappear.

This happened so often we suspected these automatic issues were actually orchestrated to secure more margin.

The Amazon rep told us that he had quotas to hit of new margin targets for us every quarter.

We also consistently had issues of Amazon reporting under-deliveries and holding our funds. We shipped product in packages of (modulo) 8, and so they ordered in packages of (modulo) 8. When it arrived at the warehouse, they'd mark only 7 delivered, which is not feasible, sell the extra one and refuse to pay us for that 8th unit. This amounted to millions of dollars.

I eventually tracked every single package we had ever shipped and presented evidence of this fraud to them. They offered to pay us 30 cents on the dollar if we signed a waiver forgiving the rest.
Most dystopic feature:

> Audio Watermarks: Turn this on to embed a user's personal information into the audio as an inaudible watermark if they record during a meeting. If the audio file is shared without permission, Zoom can help identify which participant recorded the meeting.
(In my professional experience) Google is absolutely terrible at B2B, their support is sorely lacking.

(In my personal experience) Google deprecates products I love at a fast pace and have for many years.

For me, they went from an air of mystery like they were the "Willy Wonka's Chocolate Factory" of shops to "just another software conglomerate", and not a particularly good one at that.
Learning as a New Engineering Manager
Middle-class families are not just the state's tax livestock.
Not sure about the Starship numbers but if its is $2m per Hubble mass, then launching 200 hubbles would be $800m, not $43m. This however is not about sending bricks into orbit. The ELT mirrors are segmented and need precise alignment with each other to micron precision. Deploying a segmented mirror in orbit has still not been done (the James Webb Telescope launches in 2021); the engineering involved adds orders of magnitudes of complexity over a single-piece primary mirror such as Hubble has. Add to this maintenance costs: a mirror the size of ELT in orbit needs a huge maintenance program behind it to work at all. The lifetime cost for such a mirror would be in tens of billions, if not hundreds. This is why such large telescopes keep getting built on Earth.
"Clearly" is an interesting word to use for something that you've imagined.

The submission was "nuked" by user flags and the software known as the flamewar detector or overheated discussion detector.
>The only cheap thing that Amazon offers is fast shipping for low-cost products, e.g. buying a $3 cable and getting it shipped for free the next day (assuming you have Prime). But for anything above $50-$100, Amazon is almost always the more expensive option.

Where electronics are concerned, for years I would go to Best Buy to look at merchandise first-hand, then go home and buy it from Amazon, because Amazon was almost always significantly cheaper (especially before they started collecting sales tax).

Now it's the opposite.

I use Amazon to find products, read reviews, etc., and then I go to Best Buy's website to order it. It's almost always the same price or lower at Best Buy, and since I happen to have a Best Buy store only five minutes from my house, I can order it and pick it up in under an hour.
Interesting - good read on the ramifications of fake news today. Love the idea of a "reputation score"
> - I'm surprised Go gets a 1.0 for thread safety, while Java only gets a 0.5. My understanding is that, at the lowest level, producing e.g. a torn pointer is not possible in the Java memory model, while it is possible in Go.

Some of the original reasoning behind the numbers is swapped out, but much of this scoring was that we were burnt so much by the ease of passing objects between threads and accidentally racing that we dinged Java. Our company's experience with Go has just been better, but Go also has first-class goroutines that mostly enforce doing stuff "right", and had better tooling around multithreaded race detection [1] especially at the time.

> - I think C++ deserves at least a point or two over C for thread safety, for the same reason it gets a couple points for memory safety. The distinction between raw pointers and smart pointers makes it a lot clearer who is supposed to be owning what, and seeing shared_ptr in the code can be a good reminder that something is likely to race.

That's a good point. We might have scored it somewhat differently if we were more familiar with C++ at the time but most of our C++ knowledge on the team was pretty old, and especially sparse around multi-threading.

> - Is Rust really harder to learn than C++? :) I'd normally give C++ a lot of points for familiarity, but that's already split into a separate row.

IIRC, the rationale was that C++ is mostly familiar concepts that senior developers have encountered in some form, while Rust introduces brand new concepts that we just don't have a good reference point for.

This is absolutely fuzzy business, and a different team will have different weights/scores than us!

I'm having much more success designing our own curriculum for our 7 and 4 year olds, than dealing with random emails and updates and changes and new things to try and blah blah blah from their schools. It takes a couple hours max to cover the bases and progress is like 2x the rate they were learning in school.

Our schools have been great at trying to stay engaged, but I feel it's more stressful than helpful at this point. Schools are still trying to accommodate a huge range of kids, and trying to keep up with everything they're putting out is a huge time and energy sink. I appreciate the schools wanting to keep involved but the way things are now it's a distraction.
While Internet makes life a bit more convenient, there are books and telephones. We can do something vs just "no education is possible!"
It seems to me that when it comes to growing and scaling their successful products, Google is data-driven. However when bringing new products to market Google basically has been driven by what leadership thinks is interesting/important, instead of analyzing what the market wants.

Sometimes they hit a big opportunity like Gmail and it grows like crazy, but a lot of the time there's actually no market for their product, or the technology is nowhere near ready to work at scale. This leads to a lot of canceled projects.
The question was what you do BEFORE the interview, not during it.
I think this is kind of a strange reaction. I don’t use any of Oracles products but is it really SO outlandish that someone would sign a deal with them?

Zoom probably had quite a bit of leverage in that deal, certainly more than they’d have with MS or Amazon. Google and MS also have competing products.

I don’t think we need to jump to foul play here. (Besides which, what are we, faithful guardians of MSFT and AMZN revenue? It’s ok if they don’t get every deal.)
That, and likely Oracle is doing it for free (or thereabout), financing it out of their advertising budget.

Zoom is the success story of these corona-times of ours; the headline alone is marketing gold, particularly considering nobody else in the "startupsphere" will ever give Oracle this sort of visibility - or even the time of day. At a time when Oracle is trying to push an image of being startup-friendly, this is better than the alternatives (each word they tweet on "helping startups" unleashes waves of mean and snarky jokes).
Who do I root for?
In this case a common Republican position is that voter fraud is a big problem worth devoting serious resources to, and that a good solution to that problem is a voter ID program, and (leaving the Republican position now) very clearly the best and fairest solution for that is just to issue an official ID for every citizen (and god knows that'd make a ton of other stuff less prone to problems/fraud, more convenient to citizens, and cheaper), but they also really don't want a citizen ID program, so even if they were well-intentioned in their calls for voter ID they'd end up coming off as incoherent and disingenuous once you put those two positions together. And that's if.
A lot of "they must be crazy" in this thread and I admit I had the same reaction seeing the headline.

However there are some options here other than "Zoom management is incompetent."

1. As others have pointed out, Amazon Google Msft all have competitive products and Zoom doesn't want to give them any more insight than they already have.

2. Oracle finally has a set of cloud products that are on par with AWS, GCP or Azure from a cost, availability, license perspective

3. They got a great deal to help Oracle change the way they do business so they can become competitive in Cloud

I don't know if any of these are true or not, but none are implausible imo
Google has earned it with a history of non-customer-focused behaviour. You reap what you sow.
Partitioning sounds like a great solution, thank you for this.
