Or is it? Say I'm a layman and I decide that in the system of math as I understand it, 0.000... is larger than 0. Yes, if I was going to be completely form with my own system of math I would eventually have to face the problems this introduces and resolve it, but until then I can generally adopt a self contradictory system and continue to live my life unaffected. Much like many people live their whole lives using naive set theory for their understanding of sets.
iPhone SE is at least 50-70% faster than top-of-the-line Android phones, and there's no way that its actual battery life would be 3 hours. Also, the phone comes with iOS.
Thanks for the interesting pointer.

I was also thinking in the direction of the compiler transforming the call-by-value struct object argument into a call-by-ref one at specific call sites. e.g. when the object is clearly on the caller's stack, is not mutated by the function and the function is not taking its address.

As Walter pointed out, you can use refs in BetterC (and of course C++) directly, but I don't see why it cannot be automatically applied to C in general.
Don't forget that (and this has been mentioned four times now in this thread) you can sell open source software. No need to beg for donations. Charge for the software and for the source code.
I remember this video when it came out. People were praising the food and it was all frozen from the bodega down the street

Why the hell would any business get into bed with Oracle if there is any alternative to it? That sales team is merciless, and the money will be extracted to the point that the victim is half dead, once the hooks are in.
sure they can impose restrictions...if they want the Govt cash.
Yes, we have a free $300 Credit and also Always Free Cloud Services just like other Cloud Vendors, give it a shot. (PS I work at Oracle). https://www.oracle.com/cloud/free/
The subtitle is "do you want to get one to try?", but I can't figure out how I would do that. I might be missing a link or something, but you might want to make the funnel more obvious.

Yeah, I borked that one. Shoot me an email at the blog contact link if you want one. I plan on making a little wordpress page to migrate specs and sales info onto this weekend.

I also have no idea what the specs are; bandwidth, drive, interface, etc., so I am not really sure whether I'd be interested. I would suggest adding a brief summary of the device's capabilities to the top.

Believe it or not - when it comes to specs, neither do I at this point. I've mostly been focused on implementing the serial console and UI features. I've got a vision for the next rev that I hope to complete in the next month or two.
This is how we use it: https://imgur.com/a/I6BD4vF
To be honest, we abstracted hooks away.

It works for arbitrary complex cases.
Thanks! That actually reminds me of something else I was wondering: why only three blades, leaving so much empty space for wind to pass through unimpeded? I understand adding a fourth or fifth would give you slightly less energy per blade, but wouldn't it give you more energy per windmill, for greater overall cost efficiency? Or is it the case that for some reason I'm not aware of, most of the cost is in the blades themselves, such that energy per blade is the most important factor?
Another option is to add an "archive" table, where deleted records are moved to that table.

It can get complex (for example foreign keys need special handling).

One option is table partitioning: https://www.2ndquadrant.com/en/blog/postgresql-12-foreign-ke...

You partition the table based on deleted or not, and then query either both tables together, or just the active table.
A lot of Asian countries are indeed showing that this is possible. That's good news!

According to Louis Rossmann, it is a myth. Baking GPUs don't re-flow the solder, the recommended temperature is too low for that anyways.

Instead it just "agitates" stuff at the molecular level, which can get the card running for some time. It is not a permanent fix though.

Worth noting that Louis Rossmann is a professional repair technician, so he may be a little bit biased, but he has good arguments.

I tried the heating trick on several occasions and on a variety of devices. Usually with just a hair drier. It tends to work. Great as a stopgap, but expect to replace the part later.
Yes, the technology behind zoom can be repicated in less than 2 years and for less than 100m.
I've read so many of these announcements over the years. I always end up being disappointed.

Lithmus test:

1. Is there a .torrent?

2. If not, is there a batch download mechanism?

3. Why not?

IMHO: I think museum curators do it this way because they feel doing it more liberally would strip them of their power.

(Also: why would anyone downvote this? I'm puzzled.)
If you want a more indepth explanation of what is happening in the cab and in the seed planter, check out Dodge Brothers Farm on youtube. He does a really great job of going through the details.

https://www.youtube.com/watch?v=OjVZoniN2no - how a modern corn planter works
https://www.youtube.com/watch?v=KxMcl7ktEP0 - inside the cab of the tractor for a planter
I'm guessing that video is taken in the US since she is planting corn. Here is another video from Southern Saskatchewan. People might be interested in the equipment being used. Mike is quite an character. He works on a big operation, I think over 20k acres. The equipment he is using costs a fair bit of cash. The seeding system (para-link hoe drill) and tractor to pull it likely costs between 500k and 1m CAD. They have multiple units like that.

https://www.youtube.com/watch?v=uM5ZBNzvKz4

The video doesn't show too much of it but Mike's equipment a bunch of technology on it as well. Some of the stuff:

- auto section control: turns off/on seed & fertilizer automatically to minimize overlaps and prevent skips. On large machines (e.g. 80 ft) the cost of overlap is quite significant. The seed and fertilizer is carried by a pneumatic system and optimally tuning the system is a bit tricky (he shows a bit of that)

- auto rate control/variable rate control: with variable rate, the field is split into many zones and the applied rate of seed and fertilizer is optimized. That's a whole topic into itself, I won't explain here.

- population/blockage monitoring: this system monitors seed and fertilizer flow in the pneumatic delivery system and will alert the operator is something is wrong (blocked run, rate to high or low). That's the "Agtron" system he is talking about.

- I don't know if his para-link drill has it but there is a variable packing system available. That will monitor packer (the wheel behind the seed opener) and adjust packing pressure depending on field conditions. Wet areas of the field will need less down pressure compared to dry areas

- As is typical these days, GPS mapping, guidance. He has two different screens showing the map. The Deere screen doesn't show the individual on/off sections of the drill and so it shows more overlap. The Topcon screen (comes with drill) shows the sections.

- The system for controlling the metering on the drill is fairly advanced. For planters, it is typically more advanced yet (corn seed is really expensive and so very precisely metering it and placing it is key). On the Bourgault drill he is using, there is a variable speed hydraulic motor on the metering system with a feedback control loop to control the rate. Early in the video he is calibrating those meters so the system knows the mass-flow feedrate of the meter (e.g. RPM of meter -> lbs/min of material). That feedrate will be converted to a per-unit-area application rate. The variable rate prescription map will provide input to the rate controller.

Just some info in case people are interested. Running a profitable farm is a challenge and most farmers are aggressive in adopting any new technology that will help them get an edge.
Agreed, I'm surprised "did it work?" does not seem to be addressed.

According to:

https://www.globalsecurity.org/military/ops/popeye.htm

"In the end, however, it proved impossible to determine the amount of additional rainfall caused by cloud-seeding rather than other factors, and thus justify the recurring outlay. The Defense Intelligence Agency estimated that seeding increased rainfall "in limited areas up to 30 percent above that predicted for the existing conditions," but this figure admittedly was the result of "empirical and theoretical techniques based on units expended and the physical properties of the air mass seeded"-in short, a scientific guess. Sensor data showed only that the enemy consistently experienced difficulty keeping traffic moving through the monsoon rains, a normal problem for that time of year."

Doesn't have to be free to get mindshare, though it helps.

Multics lost the mindshare battle when Berkeley started distributing BSD. They would have had to go open source / free way back then, in 1978 or so.

Mindshare, mindshare, mindshare. That's the key for this sort of thing.

Oracle, for example, locked in SQL mindshare long ago. I'm not sure that Larry Ellison understands this -- after all, he (well, Safra Katz) killed OpenSolaris when that was a vehicle for gaining mindshare. But then again, maybe it was too late for Solaris anyways.

Amazon also own video-conference product Chime.
This is why officials in many states, even ones that were gung-ho social distancing like California and Washington, were reluctant to close the schools. It was predicted that a large number of kids would instead just be congregating together on streets, defeating much of the point of closing the schools. But they were caught between a rock and a hard place. If they didn't close the schools, the kids become an infection vector that undoes much of the sacrifice of having people wfh, avoid social gatherings, and cancel large events.
Amazon has Chime.

Not heard of it? You aren’t alone there.
Are you saying that Cantor showed you can have 0.9..4?

I'm not even remotely an expert here, so I might certainly be wrong, but I don't understand how Cantor's theorems show an ability to stick a finite number and stop on the end of an infinite number.
Finding an Error Needle in a Real-Time Haystack
The US has an obsolete, anti-competitive regulatory regime. In many states, the system allows local governments to grant effective monopolies each to a cable video and telephone provider. So many communities have, at best, two internet providers, and cable video service is far from universal. So a lot of places only have DSL over copper phone lines and that's rarely at broadband speeds. In my community the monopoly phone provider is bankrupt and has not repaired lines, meaning not even DSL is available to some homes.
The idea is modularity. This is just for seed planting, but you can swap out screens for different tools attached to the back.

Also a lot of the screens can be attached to different machines, and or carried mobile which is useful.

Thats what contact tracing is. Your dinner companion finds out they are sick two days later, and everyone they were in contact with gets found and tested.

The amount of testing the US is doing is indeed a fact, and it's widely reported in US press.
It's not a restriction on the jobs, it's a restriction on the loan or even a restriction on conditions under which the loan will be forgiven without being paid back.

Edit: Now that I've seen a mirror of the article, this program is about buying bonds that have to be paid back with interest no matter what. Point stands about the conditions being on the buying side though.
Zoom feels like a pied piper-eskque app to me. Awkward and clunky to use, lag and issues are expected. Doesn't help that we've been given no guidance from higher ups on how to use the software, so we've been discovering features as we go. Today I finally learned how to let someone else share a screen, and that button was not where you would expect.
Corporate inverted totalitarianism at work. Corporations using the pandemic to ostensibly justify their poor service and ruinous treatment of others is what they do. They're not your friends and basing your business on them is a critical mistake like not owning the mineral rights to farmland.
To be fair, the Fed is buying corporate bonds, essentially lending them money with interest. Yeah, it helps businesses but then I doubt the Fed will lose any money in the long term.

Ouch. That's bad alright.
I think if you're trying to "prove" this using axioms, you've already lost.

The problem isn't that you can't come up with axioms to convince people you have a proof - the problem is with people not understanding that 0.99999.... is not a number - it's one representation of an abstract entity called a number.

The problem is, the maths required to actually define the concept of a number is fairly complicated, so it's hard to explain to someone why all of these axioms make sense in the first place.
Cryptoindex AI Daily Predictions and News for 04/28/2020
Wow, that looks like exactly what I've been looking for.
I hesitated on bringing it up. It's counterintuitive, but I'm always reluctant to do too much to speed things up when it comes to mass communication and building consensus. I realize that it is basically a legislative DDoS attack; but it is also a way to buy time to organize thoughts and filter information for both sides while also depriving the body of the benefit of an overly expeditious vote.

Would it be nice if everyone could just agree and move along? Yes, yes it would. Unfortunately, supermajorities are the realm of Walgreens advertising, and I still don't accept that there should not be mechanisms through which delay can be enforced.

Then again, I'm not terribly well read up on legislative procedure either, so I may be pulling postulates out of my arse. If anyone is better versed in it, and wouldn't mind some explanation, I'd be quite interested.

Then again, I could just read the damned rules. Is it strictly Robert's Rules of Order proper, or some specialized set of procedures?
I didn’t really see anything wrong in the thread but you use words like “calculus” and I honestly don’t know exactly what you mean. Do you mean the plug and chug methods often taught in high school? Or do you mean the application of a set of theorems derived from the axioms of a given system of numbers? If you mean the former then perhaps we can clear up some misconceptions which are clarified by the latter.
Homeschooled children consistently outperform publicly schooled children. There's plenty of verified sources out there from which to make your own conclusions, if you look.
Internally I'm saying they're real numbers. In what I say to the person trying to intuit that 0.999... = 1, I'm deliberately avoiding talking about number systems. I'm assuming this person thinks of numbers as sequences of digits, possibly with a decimal point.
I should have worded my question better, I was just surprised why you would leave out arguably the top 3 companies and go with something like Oracle. (Maybe I am too young and that's where my animosity for Oracle comes from, but I feel like they are way behind the curve in terms of their cloud).
> autonomous guidance systems

They can do simple stuff like steering in a straight line at a constant speed or offset from a previously driven path. They still require a driver in the seat and more complicated operations like for example: unloading into a grain cart from a combine still has to be done by the driver.

There is work being done in this area though.
Yeah, that was my intent, when (while) it is suffocating competition things are ok to good, not so much after.
My guess is simply, they don't want to fund their own competitors. Microsoft is a direct competitor already (so is Google,) and who knows what Amazon will do. That really only leaves IBM and Oracle. I've always been baffled when someone hosts on their competitors' platform. Like Netflix hosting on AWS, and Grocery Stores hosting on AWS. Microsoft & Google rarely have that problem (except on this one.)
Maybe try this: do longhand division of 7 by 7 or 9 by 9 or whatever, but instead of putting 1 in the first place, start with 0.

The irony is that for kids that are actually homeschooled, they spend maybe 2 to 3 hours per day doing schoolwork. That kids spend so long in public school is not to their benefit, but to the benefit of those that need to keep their parents away from them for 9+ hours a day.

I can barely attend several hours worth of digital meetings, and I'm an adult. Imagine a 7-year old trying to do the same thing. Ridiculous.
To be honest I’ve not really linked these two concepts together before so I could be missing something. Surprises are emotional responses to sudden or unexpected events. Counter intuition deals with the truth value of facts that go against what you might otherwise expect. I guess you could have a surprise reaction to learning something counterintuitive but I don’t think I have.

The first link I get when I google "accuracy of death certificates" is this one:

The accuracy of death certificates. Implications for health statistics.
https://www.ncbi.nlm.nih.gov/pubmed/1871957

> Significant discrepancies between the two documents were observed in 50% of patients. In 25%, the immediate cause of death was incorrectly stated on the certificate, having been assigned to a different organ system in the majority of those cases. In 33%, there was disagreement on major disease other than the immediate cause of death.

Anecdotally, elderly people I've lost had completely wrong death certificates. When common sense, anecdotal evidence, and a cursory review of the scientific literature point in the same direction I'm going to assume that's the way it is.

Also, try to be kinder in the way you communicate.

Cleo Capital’s Sarah Kunst launches a fellowship for laid-off workers
Hey, I worked on the touchscreen at the end of the armrest. Internally at John Deere it was called GSix (6th generation). Built with Qt, WindRiver Linux, ran on a custom board (that 1"+ thick display is _just_ the monitor), resistive touch screen, speaks CAN/j1939/etc. One of the things it talked to was a buggy Bosch radio over a home-grown protocol that didn't actually expose the radio's state, so the display was forced to make educated guesses. This was a huge pain, especially WRT bluetooth pairing (at one point we had an error screen that told the user to just power cycle the radio because the display has already tried everything we could think of to get the radio back into a good state).

The contractors for whom I originally took over apparently had a contract to write unit tests, probably for a certain amount of test coverage or something. There was a bunch of dead code buried that was only executed by the tests, apparently to bump up their unit test coverage. This was one of many such horrors. We ultimately told management that it was cheaper to rewrite the thing than it was to fix their backlog of "must have" bugfixes, and it was a huge success. Still didn't fix the radio issues, however.
Did you not read the news that Amazon uses data to compete against its own customers?

Theoretically the answer to all your questions is yes. Simply said (but not false AFAIK, I work in the field): stimulate the correct group of brain cells and you can achieve pretty much anything you want; after all everything you do/feel/think is done by having groups of cells activated and communicating with each other somehow. The main problem is finding those groups of cells.. There is an incredible amount of research left to do on how to do it because what we know about the brain is still much less than what we do not know, and the implementation (hardware etc) is also complicated on all levels you van imagine.
Ask HN: Personal Finance Tips During Covid-19
The economic fallout from COVID-19 has led to mass layoffs, hiring freezes and personal financial strain for many. I recently found out about the PUA program which allows business owners, self-employed, independent contractors and others not traditionally covered under unemployment assistance to receive assistance [1]. Additionally, it may be advantageous for some to convert any pre-tax retirement accounts to post-tax if you expect to fall in a lower tax bracket for this year (due to layoffs, etc).
