Hey all, I run a presentation sharing platform called Sizle, it's still quite new to the market having only been around for about a year, but I'm hoping that it might be useful to some people here.

Because of what's going on with this pandemic (some of my family work in high school education and I've seen the pressure and chaos that is really unfolding there), I want try try to do something to help and am giving lifetime Pro subscriptions Free for all K12, university and college educators and staff (and anyone else in the field).

If you know someone in the field, or you try it out yourself and want to take this up just enter either of these codes. I'm also happy for anyone on HN to use the codes too :)

EDUPRO100 (100% discount on monthly license)

EDUANNUAL100 (100% discount on annual license)

How Sizle works:

- Upload a PDF or PowerPoint presentation

- Send it to one or multiple recipients with optional password protection

- You get notified when the document is opened

- You can see how much time the viewer spent per slide

- You can optionally add a custom questionnaire to the end of your presentation

I know it's not much and I know that remote learning is won't be the norm moving forward, but I hope this helps at least someone during this crazy time regardless

All the Linux remote desktop server solutions are bad enough over a WAN that I typically VPN into my office, then RDC from my home Windows box into my office Windows box, then ssh -X from there into my office Linux box. It's kinda crazy, but it works better than anything else I've found, and I've tried almost all the options mentioned here. I wish there was a better way, but I don't think there is (for me)...
Well, just don't expect it to work in sunlight.
There is a rather obscure book titled "If Hemingway Wrote Javascript" by Angus Croll https://www.goodreads.com/book/show/21487480-if-hemingway-wr... that contains literary reviews and source code in a variety of programming languages.

It's hard to describe this book; look at an excerpt at https://blog.honeypot.io/if-hemingway-wrote-javascript/. The source code actually runs and really does capture the writing style and idioms of the purported writers. I remember a factorial program by "Richard Feynman" that used numeric approximations that was just brilliant.
I don't think so. I have no legal training but I think there is a difference between a firearm and a nuclear weapon on grounds that the interpretation of the second amendment is at a personal/militia level rather than some kind of national threat that would warrant use of nuclear weapons.
don't forget entertainment - netflix, youtube, tiktok disney+ etc...
An Open Letter from Our Chairman and CEO
He made 20% one time on less than $15,000. He sold when it happened to go up and got lucky. Dodgy stock picker newsletters in biotech make recommendations every day, he’s just as likely to have followed one of their trades than anything else. Unless you produce actual evidence that he has some connection to that company and acted on non public information it’s just speculation. And even worse, it’s damaging to the guy. Frankly it’s ridiculous that people have formed such stirring opinions here based on such limited data and experience.
Yeah, you're right about ear damage coinciding with exposure time - short bursts would have to be very loud to cause real damage.

And yes, it would be weird if a frequency range spontaneously inverted - the only scenario I can imagine that happening in is some jerk doing it on purpose.

The reason I became interested in ANC was because every night I would hear a terrible frequency being emitted from the air conditioner units above me (top floor apartment building), and during my experiments I quickly realized how hopeless it would be to effectively combat them due to the varying intensity of the sound throughout my apartment, the dynamic interactions of the sound with itself within my echoey wood floor studio, and my location at any one time. All valid points though, thanks for chiming in. I learned more about ANC :)

Edit: Btw my goal was ANC via speakers, not headphones. Headphones would be much easier since they only have a single, summed audio source.

Running PayPal vs Space X vs Tesla requires a ton of different skills and competencies. Tesla is a huge engineering effort and assembly line engineering effort. They've pioneered a number of innovative technologies and approaches. Likewise, Space X has pioneered incredible technology and you can't simply be a passive CEO to achieve those things. It's not like running a laundromat. Musk is a central figure in both of those companies. If you watch his interviews, he has a deep understanding of every level of engineering in both of those companies.

My friend and I have been working on this site http://feedvix.com that’s sort of similar. It’s a random mix of news articles, jeopardy questions, xkcd comics, Investopedia terms, jokes from the 80s, chemical elements, notable quotes, and Wikipedia articles. It’s good for when you run out of content from whatever you typically read.
But she misses the demographics. The US has some of the best demographics of the G20. Germany, Japan, and China all have much worse demographics, and will change into net spenders (i.e. retirees) instead of net savers.

Within about 4-10 years (depending on the country), they will be producing less and less for export to the US.

Heck, Germany’s GDP is roughly 50% exports. That’s unsustainable.

US policies are turning more inward, and countries that rely on exports to us will suffer.

The dollar will be strong for the foreseeable future. It may go up and down a bit, but overall it will be very high. The dynamic driving currencies is very different from even 5 years ago.

As production moves out of China, they will get weaker. We have already seen peak China (and US voters will insist that drugs and PPE are produced in the US so we don’t run into a supply chain issue like we’ve seen over the past two months.)

The EU banks (well, certainly the German ones) are basically insolvent. They were never recapitalized after 2008, and have limited power.

So there is nobody around to challenge the US. As well capitalized consumers, the US controls their future.
> So now you accept that I wasn't off by 2 orders of magnitude.

You're right, but it doesn't make the numbers you're citing any more relevant.

> SARS, MERS and COVID are not flu viruses, they're coronaviridae. H1N1 and H5N1 are mutations/subtypes of the Influenza A virus. The coronaviridae are different.

Who is being pedantic now? The point is that novel viruses are not a once in a lifetime occurrence, so you can't compare the risk of "COVID-19" to "lifetime death rate", since a new novel virus will come along in a few years. The danger is not covid-19 in particular, but novel viruses in general, and doing nothing would lead to a 1-year fatality rate for a novel virus on par with the lifetime danger of driving. Which means the lifetime danger of the virus is 20x or more the danger of driving. That's

> The study I referenced mentioned 0.1% for the flu vs 0.37% for COVID. Feel free to read it. That would make it 3.7X not 30X. Because the flu has been around so long the fatality rates are largely determined by mathematical modeling, and are very close to the actual fatality rate. On the other hand, we're still figuring it out for COVID.

Yes, but the CFR of the flu is well understood. The CFR of COVID-19 is not, and your entire argument is based on one study which is not conclusive, has had some flaws pointed out elsewhere in this thread, and generally doesn't match observed CFR elsewhere.

> Which is why, scroll back up, we isolate the vulnerable.

Which, ask any epidemiologist, doesn't work, since hospitals get overwhelmed anyway. The hospitalization rate of young people is still pretty high (maybe not quite 20% as it is for the overall population, but still more than 10%), they just don't die with reasonable care. There's a fair number of cases of healthy 20-something year olds who end up hospitalized for a week due or more due to COVID and need ventilators. Not to mention healthy something 40 year olds.

Even if you manage to perfectly isolate every at risk person, there's still a nontrivial risk of overwhelming ICUs anyway. And then the fatality rate among young people would go up as they couldn't get good care. And you're not going to perfectly isolate every at risk person. So the you have more young people hospitalized, more old people hospitalized, and well you're in a bad spot.

Or you end up expanding the definition of "at risk" to include "obese, heart disease, diabetes, or high blood pressure", and you've ended up essentially where we are now, with the majority of the US population in an "at risk" group.

> SK has not tested huge swaths of the population, they've tested around 1%

You realize that for population level statistics, that's fine. That means that 490000 tests have returned negative. If, as the Italians think, 10x as many people are infected, somehow there would need to exist 100K+ infected people, showing no symptoms, basically none of whom appeared in the 490000 negative samples. Such a probability is negligible. The sample sizes are large enough to remove the possibility.

> But a virtual index fund that tracked their purchases and sales to make a record of how well Senators do in the stock market

I think it's kinda funny that you called a stock index as a "virtual index fund". Feels like we've come full circle.
I have done extensive work with monoliths, and extensive work with microservices. I quite literally have never seen microservices be a benefit in the way you are describing, and if anything microservices can make the problem of robustness more difficult, because in many workflows there are one (or many) services that are critical. If they're down, everything is down, and if anything distributing these dependencies across different systems can make it more difficult to determine where the critical points of failure are.

As you point out, there is nothing inherent in a monolith that makes it less robust. I currently am building a monolith that is deployed on auto-scaling servers on a cloud provider, so if one server dies it just spins up other instances.
I mean isn't that a problem with the original proposal too?
GNU COBOL runs on pretty much anything. You can play with it right now. No need for a mainframe. In fact, a lot of COBOL code running these days is not running on mainframes.

Mainframes are not big Unix boxes. Their OSs were evolving for decades before Unix booted for the first time and are very different from anything most people have direct experience with. You can boot up a legal copy of MVS 3.8j (or an illegal one of its modern descendant z/OS) but expect a learning curve. You can also get something similar from Unisys for their Clearpath machines.
The first rule of COBOL programming is you don't talk about COBOL programming.

The second rule of COBOL programming is...
> But, what distributing some of the components into so-called microservices would give you is a graceful failure scenario where even if all the instances of a specific component fail, the rest of the application still works. Maybe only one function stops working temporarily but most work continues on.

The important thing to note here is that microservices give you one way to build a graceful failure scenario. You don't get it for free. Often that 500 will propagate all the way back! So you have all the same failure modes + network failure modes!

You could also build a monolith that could handle component level failures, for that matter. Tooling doesn't seem to be as common, though.
Being a worker is not how to get rich. Don’t think it ever has been.
No, the truth appears to be boring and ordinary.

The senator bought the shares on the 28th; the day the company issued a press release. If you go to the link below, you'll see what looks like it might be insider trading by others, but that occurred on the 23rd, not the 28th. He bought along with everyone else when information was public and he sold to take a quick gain.

If you go to the link the parent provided and set the range for January 3, 2013 through February 3, 2013, you'll see the following:

-The stock traded at around $2.80-$3.00 from January 1-January 22. In other words for almost all of the month.

-On January 23 (Wed) the stock jumps to $3.75, stabilizing to around $3.30 a share by January 25 (Friday). Something is happening

-On January 28 (Monday) the stock gaps up and opens at around $5.00 a share. That day at 7:00 a.m. the company issues a press release that it has had success with a new renal drug:

> is there a tradeoff in how the message spreads vs how convincing it is?

That doesn't make any sense, viruses that are more fatal don't spread well because dead people are not good spreaders. Very sick people are also less capable spreaders than someone walking around with a persistent cough. Someone who's convinced would be MORE likely to spread a message.

A forecast that has nothing to do with reality is garbage.
Feedback - in the "about" section, this sentence is broken: "Since there is no major reprecussion for insider knowledge trading for a senator or member of congress to act on the best behalf of their wallet." Either drop the "since", or replace full-stop with a comma to join the following period.
Yeah, whatever. People have been saying that in the US for decades. No one listens.

Not going to change now.
Almost 25 years ago I took a TCP/IP class in Chicago that turned out to be a waste of my time, because it primarily dealt with clients like ftp, telnet, etc that I was already quite familiar with.

However, the rest of the students were mainframe guys, so it was an interesting few days. My (Solaris, Linux) world seemed incomprehensible to them, and vice versa, but it was nice to get a glimpse into how the other half lived. Finding experienced computer people who’d never used ftp was quite surprising.
Anyone familiar with the history of how PDFs became such a widespread format in the first place? I get that it looks nice but not being able to edit it by default just seems weird to me.
Very interesting etymology indeed. The relationship is much clearer between cybernetics and the transliterated Greek kybernetes and the occasionally used word gubernatorial (or even more clearly transliterated Russian gubernator).

Cybernetics

Kybernetes

Gubernator
Anonymous sum types. Most enum variants I write are single use, or very few use. We have anonymous product/record types with tuples (function returns all-of) but not variants (function returns one-of). Something like fn foo() -> (i32 | f32 | String). I'm not the first person to suggest this idea, and it's been done in other languages.

As well, having to match against Enum::Variant0, EnumVariant::1, etc, for all arms of a match statement instead of inferring that it would be Variant0, Variant1 is tedious.

These changes would be difficult to implement and I know some people prefer to have all of the explicitness in their code. But one of the most common complaints outside the community is that prototyping in Rust is slow. Not just because of the borrow checker, that's easy once you learn it. It's the over-emphasis on explicitness at the expense of ergonomics.
Influenza's 0.1% isn't from clinically significant cases.

Influenza is 0.1% from estimated total cases.

Here's the CDC's preliminary in-season influenza report for this year, showing 39,000,000 - 56,000,000 estimated cases, 18,000,000 - 26,000,000 medical visits, and ultimately 24,000-62-000 deaths (0.061% - 0.1107%)

These preliminary estimates are roughly in line with recent years.

> making a temporary commit in order to checkout to another branch to work on things

That's a Git bug.
Some other commenters have discussed it, but one thing to make very clear that I think a lot of people are missing:

1. I fervently believe, after having lots of experience with both microservices and monoliths, that microservices do not provide any technical advantage over monoliths. If anything, they can make a lot of technical details more difficult.

2. Microservices, however, can solve some particularly thorny organization problems for large teams with respect to how these large teams build complex software systems.

Thus, in my experience microservices can serve a useful purpose, but they will only be as successful as your organizational-wide communication is.

Furthermore, for the developers replying "I don't see why I'd ever use microservices for project xyz", well, if you're a team of 1, there is hardly ever a need to use microservices.
So give up, then
> We had a bunch of small services built and maintained by one person.

That just seems like it'd be a disaster at any non-trivial scale.
LOL. Sorry about that. Not sure where I got my wires crossed there. Must have gotten distracted somewhere in the middle while looking it up. I also didn't realize that Feinstein was that old.
I was hoping for something that thwarted the processing in the CCD (chip that captures light in digital cameras AFAIK) instead of something that just thwarts the recognition algorithms.

Of course, if the camera still captures a perfect image, that image or video is always around to be processed at a later date.

How would you describe the difference between an Object and a Map in Pointless?

Having read the documentation, I don't see any difference other than whether non-string keys are allowed, and as a result the syntax for value access (`obj.key` vs `map["key"]`).

And one of the things I've been wondering about with regard to language design is why more languages don't take a Clojure-like approach of fully merging the concept of "object" and "map", since they seem to cover so much of the same ground.
It's quite clever, actually. Offloading specialized work to autonomous subsystems allows the CPU to run your code better than it would if the CPU also had to deal with reading from disk or assembling packets for the network. A modern mainframe has tons of such systems and that's what allows them to process volumes of transactions that PC-based servers of the same price range can't.

In fact, our PCs are like that because they had to be cheap and the cheapest way is to burden the CPU with all work.

Note that years ago, Moxie has studied a similar problem of how to let users know if their contacts use Signal or not without uploading the whole address books like e.g. WhatsApp does [0]. It's similar because in both instances you want to "match" users in some fashion using a centralized service while keeping their privacy.

He ruled out downloads of megabytes of data (something that the Google/Apple proposal would imply) and couldn't find a good solution beyond trusting Intel's SGX technology, arguably not really a good solution but better than not adopting it at all [1].

You have kind of a computation/download/privacy tradeoff here. You can increase the time interval of the daily keys to weeks. Gives you less stuff to download but the devices have to do more hashes to verify whether they have been in contact with other devices. You can increase the 10 minutes to an hour. That means less privacy and more trackability, but also less computation needed.

My guess to why Google/Apple didn't introduce rough location (like US state or county) into the system was to prevent journalists from jumping onto that detail and sensationalizing it into something it isn't (Google/Apple grabbing your data). Both companies operate the most popular maps apps on the planet as well as OS level location services that phone home constantly so they are already in possession of that data.

An early reason is that email, being all public protocols and interoperable and all, is less end-to-end encryptable than an app where you control all the code and systems.
Really? I agree "a new remote desktop" makes me suspicious about usage over WAN because most all suck. I didn't have great luck with Windows Remote Desktop, either. We went with TurboVNC/VirtualGL on the server and recommended, I think, TurboVNC on the client (via ssh). I used macOS Screen Sharing.app because it wasn't Java and was more comfortable to use IMHO (with things like screen scaling and fullscreen). Most other VNC clients performed significantly worse. I usually ran the desktop around 1440x900.

This seemed to be the best setup with high latency and low bandwidth situations. We had people spanning the furthest time zone.
You can still consider it a breach of the contract.

You're making a significant assumption there. Let's not pretend that people only switch to Chrome because of some perception about performance. If that were the main or only reason, shouldn't lots of people have switched to Firefox later, if Quantum made it so much faster?
