Well, the hats drop to the floor and the scuffle begins. After all, it's reported Facebook is preparing a blockbuster lawsuit against Apple for being a monopoly.
India’s tumbling Covid cases raises question: Is the pandemic burning itself out
It's not like there's a fair competition between people today. The richest babies already have extraordinary advantages over poor babies.

It really just exposes that people in power don't want to make it obvious that they've got an unfair advantage, and that basing society off of competition is what's bad.
Of course! A very large proportion of my net worth is VTSAX. Target retirement funds are potentially an even better option for the average retail investor.

But the educational part comes with teaching people why this approach tends to have better outcomes than others and also to help instill the understanding of how panic-selling during a downturn is a losing strategy of "buy high, sell low".

I didn't have significant assets during the 2008 crash, but I certainly did last March. And even though I've advised others to buy and hold for years, it took a lot of self-discipline and self-reassurance to not throw that all away and exit the market when it became clear what the extent of the pandemic was likely to be.

Even today I don't think I fully understand why the market has done as well as it has. But I do know I'm glad that in the end I was able to stick with the game plan I've been preaching all this time.
It's virtually guaranteed that this stock popped up on the radars of the funds who run momentum trading strategies. And it would be very weird for a lot of them not to jump on that bandwagon (at the very least because it's their mandate to do so).

I've always thought that was a marketing trick. After all, how could all the bandwidth and development time and resources I was using only cost $1/yr?

However, now that I know how lean the team that built WhatsApp was, the math does check out, and it's amazing that all it costs to keep the bullshit at bay is $1/yr.
Worked at grocery stores and gas stations. A lot of people stopped just to use the restroom.

We also had homeless people use restrooms to bathe, and drug addicts use the bathroom as a place to quickly take a hit. Also had people defecate on the floor, write messages on the wall with feces, etc. Because of this, multiple places I worked didn't provide restroom access to the public. It sucks for people who simply and respectfully use the restroom. But at the same time (in one specific location at least), it was a matter of having to clean up fecal matter or drug paraphernalia or not letting the public use the restroom. My sub-living-wage job simply didn't pay me enough to put up with that crap.

That being said, if you let 'customers' use your restroom, you should let gig workers do the same. They aren't your direct customer, but show them a modicum of respect and dignity.

Judging by their "How does Bedrock Linux Work?" section[0], exactly how they fix this hard problem is via an ever-evolving plethora of specific per-system fixes, which they're trying to stabilise enough to document before their 1.0 release, but is likely to continue changing as needs arise. Sounds challenging.

You're right. I only meant to shine a light on the alternatives that one has to using Robinhood.

I wouldn't move off of Robinhood for this issue, but there are a number of other reasons that I would advise others from using the platform, including poor order fills[1], constant outages, and overall lack of features.

> In a Lisp, though, everything looks more-or-less homogeneous. ... you can't quickly tell whether some thing you're looking at is data, a function, or a macro, or what. It all blends together into a disorienting fog.

I wonder if this is a feature of Lisp, instead of a defect.

When you call up a variable or a function or macro, the intent is to return some kind of result. If variables, functions, and macros all look alike, and then maybe it can be weaved more seamlessly into the code to create its own style.

You can also think of a variable, as a function call with zero parameters.
Why be sorry?

Fact.

Conflating an explanation that says why a lie was necessary somehow with the idea of that making it all not a lie happens a lot.
Sounds like you're looking at the right contract. Option contracts are written to give the buyer the right to buy/sell 100 shares. So, the minimum investment for the $320 PUT is ~$24K. Contracts with lower exercise prices will be less expensive, but carry more downside risk.

If the governmental body is not interested in ensuring efficiency, than no matter what structure is chosen it will be abused - by inflating counts, or costs, or some other way, because people who have incentive to get money and no counter-incentive to follow the rules will cheat. Not all of them - but enough of them to cause serious damage. Look what happened in California recently - about 27% (!!!) of unemployment benefits is now thought to be fraudulent. This is what happens when people are incentivized to cheat and people who oversee the public coffers aren't incentivized to guard them. You'd expect that there would be some consequences for CDC leadership for their numerous failures - but that's not happening.
"Probabilistic" markets will be (and to some extent already are) re-invented on-top of the blockchain.

Current generation cryptocurrency blockchains are more similar to the post-trade settlement system, where everyone figures out who owns what after-the-fact.

Maybe smart contracts will change that, but performance will need to get a lot faster and I'm not sure how feasible it is to implement a full exchange on top of (for example) Ethereum. Would love to see it though!

The problem with un-bundling US retail is what we currently see via 3rd party Amazon sales. You end up with exploding hover boards, electrical fires caused by bad chargers, tainted or counterfit makeup etc... The appeal of Target or Walmart is that they have a duty to their customer to not sell them dangerous products and they have clout to get cheap prices. 10,000 eCommerce shops selling private label chargers exacerbates this problem. I can trace the product to a factory in China sure, but that doesn't solve my lawsuit problem. Do I sue shopify in this case?

HTC, interesting. Okay, that's the first brand I've looked into where relocking actually seems viable!

This is not a "how do I root???" situation. You have a much better brand than most people.

And I've used magisk fine, but hardware attestation is rolling out and if anything starts to require that then anyone that can't relock their phone can't fake it. Edit: And it might fail anyway according to https://twitter.com/topjohnwu/status/1278849731305672705?s=1...

Also good luck doing anything with my current phone. After long enough being unable to find a reasonable phone that had 600MHz support, an SD card, and rootability, I gave up and got a samsung. The bootloader won't allow anything.

Yes “naked shorting” is a technical failure that hasn’t been a real problem in forever, but us frequently cited by shady CEOs as cover for why their stock price fell. Patrick Byrnes is one famous example.

From this very article: “ Alan Sporn, former president and major shareholder of OTC bulletin board company Trident Systems, is suing a group of brokers who, he claims, utilized a number of techniques, including the stock borrow program, to undermine the price of Trident's stock. This attack on the value of the company's stock virtually destroyed the company, both in terms of raising capital for growth, and in depressing the value of the shareholders' investments to virtually nothing, claims Sporn.”

Sporn case was so weak the judge ruled for sanctions against him and he had to negotiate an agreement to avoid being stuck with defendants court costs.

I'm pretty sure that's how the stock market is actually intended to work. This should be obvious if you consider things like dividends. There needs to be a fixed number of shares, each with a clear owner for that to work.

This isn't really true. Let's say a company has 100 shares and they decide to issue a $1 dividend. If there is no shorting, the company just pays out $100 and everything is done.

But let's say there is shorting. Someone loans out 10 shares to a short who then sells them to someone else. All of a sudden there are 110 shares out there. So when the company pays out the $100 it's $10 short of what is required for each stockholder to get the dividend.

So where does the required $10 come from? From the party shorting the stock of course! Anyone short a stock is required to pay out, in cash, any dividends issues while they hold a short position. So it all works out.
Blockchain doesn’t keep up with Bitcoin trading either, but you can always withdraw your assets to a private wallet and not have to worry about getting Mt. Gox’d. There’s no way to “withdraw” securities from the opaque financial system, so you are always at risk of fraud.

Does this mean that there is still only 100% of stocks available and the ratio of iou's to total stocks 113/100?

I guess that makes sense that a person can borrow a stock, sell it, borrow it again from the second buyer, sell it again. The number of stocks floating around stay the same, however, the number of iou's increases. Likewise, a person can buy the one share, return it, then buy it again, and return it again to settle the second of the iou's.

Interesting that nobody is really explaining the mechanics of how this works. Makes me wonder if a lot of retail investors are about to get hurt.

This is exactly the reason app stores should be banished! I want explicit control over my software and I don't want it to update without my explicit consent. There's a trend recently in desktop software to remove features / settings in favor of a simplified mobile-first design, and too often a version from 5 years ago is better than today's.

I want to keep my software forever. Due to hardware improvements, my copy of Photoshop CS4 works even better now than it did 12 years ago when I bought it. You'll have to pry it from my cold, dead hands if you want me to switch over to an Adobe CC subscription.
To add to how simplistic their heuristics are we had a demo of one of the mentioned above ransomware detection.

Their demo was about 2 hours long, during it I’ve written my own ransomware in a few lines.

It used cipher.exe a command line utility that allows you to encrypt files, with about 5 lines of a batch script (well it was pinvoke in my case) I had a ransomware that would encrypt all document files in the user’s home directory with a new EFS cert, generate an EFS recovery agent and upload it to a webdav share, delete the EFS certificate from the system, then using the same cipher.exe utility secure wipe option (/w) nuke the file system and overwrite all deleted data to make both forensics and recovery near impossible.

Since cipher.exe is a signed Microsoft executable it wasn’t detected.

Their response was that they haven’t seen malware use this before and they were looking for windows crypto API calls, CPU metrics and other nonsense and assured us that it’s highly unlikely that anyone would use built-in command line utilities when compromising our network.
The biggest, strongest, insurmountablest advantage Google had over MS, Apple, Sun, Nokia, Oracle, Adobe and everybody else is that they didn't need to sell anything, hardware or software. They just needed a platform for selling ads. Any platform would do, so long as it would catch on and no ad competitor controlled it.
Saving money requires keeping cash (sometimes a lot of it) in the bank that could otherwise be put to productive use. Options contracts allow offloading of risk without keeping this excess cash sitting there doing nothing.

It can be much more capital efficient.
"The universe is made of stories, not atoms"

When I first came across this quote from the poem "The Speed of Darkness" by Muriel Rukeyser I thought it was all too typical glib and hand-wavy poetic license. I was a STEM person, I knew the world was made of atoms, not stories.

But the years ticked by and eventually I realized that the atoms were just stories too.

+1 for the poets.
Well, at least the hypocrisy of the app stores is now laid bare. Facebook can fuel violence and have zero repurcussions while their competitors will be de-platformed immediately if a fraction of the calls of violence is discovered.
The only correct answer to this is now. Right now. No one knows if this is the top of the market and tomorrow everything will come crashing down, or if this is the very bottom of a 10 year bull market. On average you do better not trying to time the market and just contribute on an automated schedule. Set up monthly contributions and buy regardless of whatever is happening in the market and then try to forget about it for most of the year.

From the article: "The overhead in setting up Kafka versus a very hefty Postgres is enormous, because distributed systems are hard...".

If you need a message queue what is the alternative to Kafka? In my application I needed to update my Lucene search index when data (stored in flat files) is updated. I need a queue in between, so I evaluated available solutions: RabbitMQ and Kafka, and I picked Kafka. Another place I need a message queue is for notifications. When an item is updated lots of users may need to be notified and I didn't want this processing to happen synchronously so I used Kafka in between.

My application is running in a Kubernetes cluster, and I have Kafka running in a container. Never had any problems. Based on my experience I don't hesitate to recommend Kafka even for simple applications. The only negative I noticed that resource requirements are high compared to everything else I am running.
well they're not very useful then, are they.
> Finally - why assume a government agency is competent and has the means and resources required to act in a timely manner?

That's not the assumption.

The assumption is that facts manually assembled and reported by a government agency are already within the knowledge of that agency, so even if they don't have “the means and resources required to act in a timely manner”, you aren't helping by reporting those facts back to them.

(This may also be an unwarranted assumption , but it's a different assumption than you describe. I've definitely in the past—on behalf of a different government agency—frequently been involved in reporting facts assembled by one office of a government agency to the parties responsible for acting on that information in another office of the same agency who hadn't been informed of it.)
