UI malfunction happened to my mobile E*Trade app roughly from January until end of May. The first time it happened, my heart rate jumped! I only have simple stocks, and I knew the day was not as bad, but the app showed big red numbers. Luckily, switching report in the app shown different numbers... so I knew the app was not displaying the right numbers.
Which was upsetting as I had no easy way to know my real situation. Later I found out that the app was reporting fine when the stock market was open, but then lost its mind after the market close, showing random numbers (mostly in red or minimizing the gain).
Now, it seems to be fixed. But lesson learned. Actually, it happened to my dad, back in the 80's when the only way was to go at the bank and ask for the numbers. The teller missed a line and gave my dad a very bad number. He had invested portion of the money coming from the sale of our house, while the new house was under construction. The investment was supposed to be very conservative (and it was), another trip to the bank the next day clarified the situation.
I am wondering if those data issue would happen more, and if the consequences would be higher now than before ?
It is scary to me that a 20yo can play with money so easily. I am no fan of retail bank, but I would expect some "Are sure? You might lose all and more" before signing the paper. Maybe Robinhood should explicitly compute the maximum you can lose and ask you to confirm that you do understand it. Actually, they might end up with more people trying exotic investments as like me I refuse to touch it unless I fully understand the risks.
That description does not apply to me, and while I know Python, I don't use it. I do however have respect for Python.

The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

Neat. It reminds me of work from MIT’s (now defunct) Aesthetic and Computation group, e.g. Design by Numbers and Processing.
I'd love to hear about Avi Bryant's time at Etsy. I'm sure he has some interesting stories.
Yes, it will be interesting to look at the microcode. Intel's 8086 patent discusses the microcode in some detail and gives examples of the microcode for a few instructions. So I'm not expecting any huge surprises.

It never ceases to amaze me that people pay that much for transfer. It's one tenth the price on DigitalOcean and it isn't like this is comparing two different types of things.
>On that angle, why are the folks arguing "a few big tech companies have had immunity for too long, they have too much influence," not also arguing "a few gun manufacturers have had immunity for too long and have too much influence?

Not only is that a whataboutism, but its out of touch with reality...there are millions of people who believe there should be liability and giant organizations lobbying for liability gun/ammo manufactures and they have been successful, because we are now seeing liability in the courts.

Its law, think how it took decades for big tobacco to be liable when they not only knew of the dangers of their products but they actively and intentionally withheld that information from the public.

> The first of these was announced just last week when the Chinese battery-maker that supplies most of the major car makers, including Tesla, revealed it had produced the first "million mile battery".

> Contemporary Amperex Technology (CATL) says its new battery is capable of powering a vehicle for more than a million miles (1.2 million, to be precise - or 1.9 million km) over a 16-year lifespan.

I keep being told Tesla has some big tech advantage, but here they are buying the same batteries as everyone else.
In the EU, before opening a trading account you are forced by law to compile a standard questionnaire to assess your financial knowledge and risk tolerance. Depending on the results, you might not be able to trade certain instruments.
I love options trading, but I used to work for an options exchange. I don't write uncovered positions because I can't afford the tail risk.

/r/wsb, on the other hand, loves tail risk, long or short. That subreddit needs to be shutdown by the SEC. It's serving as an investment advisor for a significant number of young people, whether it masquerades as satire or not.
That's a little racist, don't you think?
If sugar was illegal you'd see the same sorts of crimes. You can't blame it on drugs or drug users the same way you wouldn't blame it on sugar or sugar users. The blame rests squarely on bad laws and those who create them.
we also have support private channels, personal messages and public channels.
You might get away with 3 (depending on load), but then you would need an additional charger ($1360 each). But there was a reason I use the ~ symbol =). Personally if I were doing this I would get more chargers, but it is really up to the use case. Either way, assuming 5,000 hours/year, you are looking around $20-30/hour of effective cost (depending on what you count for “everything else)
> 10 bit color support in graphics cards only became available around 2015.

That's off by a decade.

> 256 color monitors

Is that a thing that exists?

> We've only switched to 10 bit because of HDR.

You can get clear banding on an 8 bit output, and 10 bit displays are used at the high end. 10-bit HDR isn't immune to banding, since most of the increased coding space goes into expanding the range. There's a good reason for 12 bit HDR to exist.
No that's not a possible explanation. Look at the charts for women. 80% of women have just a single partner in a given year and 60% have regular sex every week. This hasn't changed over time. For a hidden exponential right tail to explain this, you would need to believe that women are overwhelmingly switching into weekly, committed relationships with a small number of men and no others. You would also need to believe that these alpha males are bedding all of those women weekly. That doesn't make logistical sense, and isn't the story people are trying to tell either (that a small number of men are doing a different woman every other day and keeping them satisfied and off the market).

These alpha male type men may exist, but they're a drop in the bucket compared to well documented factors like worsening economic conditions.
hmm - I wouldn't be too surprised if Tesla has their electric self driving fleet of cabs out well before that.

> Oh! Is that what those funny looking "hoods" are about? I thought for a second they might be functional, but I guess they're just decorative?

The main use of those monitor hoods is to remove glare caused by ambient lighting.
They're common (and often included) accessories for displays intended to be used for photo editing, color grading, and similar types of work.
I was kind of surprised to see one on a "gaming" monitor though.

I was speaking less about options trading and more about general adoption. I've never done options trading, just small-ish buys and sells. My experience with e-trade was a flat 10 dollar txn fee, which was totally unreasonable for the amount of money I was investing.
Do you know why that is? Is it the quality of the culture on the store bought? This also happens with me, however, the 2 rounds that I get from it are very good, thick, creamy yogurt, so I assume it has to have live cultures. Maybe I'm wrong?
Activision should learn from AWS, their servers get DDoS'd constantly.
The inability to make “serious” change quickly or at a national level is a feature.

What seems to be missed is how much easier this is at a local level. I’d like to see a lot more advocacy for restrictions on local police departments.

I’d happily support a local law that prohibits police use of facial recognition technology.
it worked because the cards were heavily stacked toward the US and other first world countries.

as the developing world improves their standard of living, so does the same decrease for people in the developed world, because these developing nations are no longer dependent on the developed one's.

It was always just a question of time with globalization in effect.

personally, i think that this is a good thing though. we in the developed world have been living unsustainable lives for generations, living off of the developing nations.

though thats most definitely not the only reason why everything has been getting harder for the working population. automation, higher efficiency, extreme concentration of wealth and more do their part in the current situation as well.
Hey for what it's worth I think this is really impressive for only a week!
Nice idea! For your landing page, I would suggest at least one concrete example to illustrate what it's for. Sort of like a user story, except visually. So, a topic that would plausibly be scattered among all of the different data sources listed, and showing your tool bringing that all together.
The rule is that you need to provide a way to buy it in-app. NOTE: It doesn't have to be the same price.

I think we need more liability here, both for the manufacturers of insecure devices as well as the equivalent of “gross negligence” for incompetent sysadmins.
I think the risk of that instance is low, since options are a legally enforceable contract. I think the brokerage has some liability to pay the contract then get the money from their client, but I don’t have my Series 7 so take me with a grain of salt.

There is always some information asymmetry and outside pressure. If a system is so brittle that it cannot function in the real world, the system is the problem, not the world.
All brokers do this because the each option leg is a separate trade and one executes in response to the other, and can happen on different days. It's the same as owning stock and having ITM options that will close that equity position, but the totals will be skewed until then. Broker UIs can be made clearer but these are basic fundamentals.

If anything, it highlights the fact that these people should not be trading in the first place if they don't understand their own positions, and brokers need a much stricter gate before allowing them access.
A generalization like “people on HN are always...” coming from a 3yr old HN user with 20k+ karma points looks like a case of the pot calling the kettle black.

Criticisms of large corporations is a healthy part of the HN community IMO. In fact, if we didn’t criticize Zoom they might still be lying about their E2EE capabilities.
So how do you define that giving away phone numbers is the right trade-off in the "spectrum of sophistication"? It effectively means lack of anonymous communications for everyone, i.e. global surveillance (personally identifiable metadata is in the hands of Zoom).

Imagine playing monopoly for 400 years with someone, and they got to go around the board for the first 300 years without you making a move, buying up all the property. Then for the next 50 they allowed you to start to make moves, but every time you started to gain just about any money they would push you over and rob you (see: sundown towns, lynching, the tulsa massacre, segregation, jim crow, redlining, police brutality, poor neighborhoods and absolutely awful schools).

There's been no penance. There's been no justice. And people aren't even asking for that, they're asking for a seat at the table and a chance to play the game, which is STILL constantly being denied. Its not scapegoating, its fighting against systematic oppression that you yourself continue to support.
I don't see how this isn't just discriminating based on national origin.

It'd be one thing if there are actually some nefarious ties between Eric and CCP, but all we are going by is he's originally from China and there could be influence by CCP on people from China. It's not bad to point out a connection, it's bad to point out a possible connection based on nothing more than where the guy is from.
My broker (Scottrade and now TD Ameritrade) called me, asking for a verbal agreement that I knew that options were high risk and yadda-yadda that can lose more value than they are worth after I signed some forms.

These instruments are very high risk and not really meant for average investors. Their primary goal is for hedging and leverage.

----------

One of the reasons for the "Black Friday" (kicking off the Great Depression) was the proliferation of leverage among people who didn't really understand it. That's why most other companies make you sign forms and ask for verbal agreements before allowing you to have access to things this dangerous.
Can you work with practitioners and issue a specific type of bond to finance the work? If so, do it!

In Lyft's case, they can acquire capital cheaper than individuals for mobility assets, at a lower cost ("green bonds"). For example, this was very much the Solar City model: They were not a solar install company, they were a financial engineering company that could go to the capital markets to finance your rooftop solar to make it affordable until the price of solar came down to where purchase is now the superior option. Lyft can encourage, finance, and work with local jurisdictions to install EV charging stations where the data shows drivers need them. They can sign a PPA (power purchase agreement) for those charging stations to purchase renewable energy for the EV fleet keeping costs under control (versus volatile petroleum costs). And most importantly, this halves the per mile costs of a vehicle (versus internal combustion), allowing Lyft and a driver to capture more revenue than they already are.

Do I think Uber and Lyft are viable businesses? Absolutely not, but I'm not going to throw shade on legitimate climate change mitigation efforts. That doesn't respect the people who are championing these efforts, or their leadership above who have to take the leap to get buy in from the business and push them forward. There is real work and hard conversations behind these efforts.
Why would I involve Twitter? The USPS takes care of that for me. Or I just use a ballot drop by my office or grocery store.
If a client/muggle asks me to build an “AI” I’ll be wary that their “spec” is sometimes just examples of what the “AI” should be able to do: play chess, write a poem.

In their mental model, the AI is far from defined by these capabilities. They won’t be happy unless there’s an actual AGI whose capabilities happen to overlap with the spec.

So my point is historically we have cheated our way out of defining “intelligence” and instead given necessary but insufficient examples. I think this is the mechanism behind the goalpost-shifting in “AI”.

That’s the metaphor: it would clearly be absurd for engineers to define Jesus by some examples of capabilities. People who are waiting for the second coming won’t be satisfied.

In the lab we maybe should define AI by some set of capabilities. But clients, journalists etc. picture the Hollywood version, and narrowly fulfilling their spec won’t actually satisfy them.
That's interesting. But did your company consider using D? if so, why did chose Rust?
I'm in the same boat. More real estate is the big win. I made a pandemic purchase of a TCL 43" 4k TV to use as a monitor primarily for programming. I sit a bit further from it: 30" rather than 24ish when working on the laptop. I drive it with a 2019 inexpensive Acer laptop running Ubuntu 20.04 and xfce. Every so often an update kills xWindows, but I can start it in safe mode and get things working.

I do find my head is on a swivel comparatively, but while noticeable without being a negative. Overall I like it. A lot. The only thing that is painful is sharing the desktop over Webex/skype. That does bog the system down and requires manual resizing of font size to inflate it so that viewers on lower resolution systems can cope with it.
Anger is not proof of anything, and that's something this entire movement does not understand. There is fundamentally no evidence to support the notion that equality of opportunity leads to equality of outcome. That goes for the justice system.
Or, maybe address the systematic realities that make companies act this way over and over for centuries.
Maybe the best move is simply to not play the game. FB is clearly focusing on their customers, the ad-buyers and influencers.
That's why I like the idea of doing these sorts of projects in the deserts - where the zoning and county codes are often a lot more lenient, and you can be far enough away from anyone else that NIMBYism is almost nonexistent. I've been contemplating the idea of desert hacker communities for a long time, and may move forward with that at some point (anyone else interested in chatting about it, feel free to reach out).
Lots of companies are moving away from full featured web clients. I think Venmo recently removed the ability to send money -- you know, the entire purpose of Venmo -- from the web client.
Next thing you know, people will be using E2EE to stream gasp copyrighted material!
Government can't really solve it either, but Cooperatives are a great way to handle it in my opinion. Next to individual ownership, it's pretty much the only thing where the interests align.

You don't want to live in government housing when money is tight and some company offers a quick buck to pluck up that hole in the budget. Coops don't have that problem, they can't be sold, as they're owned by their members, which are largely also their renters.
This is awesome!

I love that there a groups later in Startup School that are for later stage companies.

I can see a progression where based on the stage and growth of your company you get different peers, investors, advisors, and off the record content.
Or perhaps to acknowledge that the assumptions about a free-market ignore the realities of human psychology, and thus a free-market inherently cannot exist because humans are not capable of producing a free market without regulation, and regulation is antithetical to a truly free market?
Yeah as uncomfortable as it is to say, you have to put some blame on the 20yo with no income who decided to play with financial instruments beyond his knowledge..

There's a broader tension here with the _perils_ of democratization and freedom that I think is a common thread shooting through many of the issues the Western world is grappling with in the information age

How to Develop Inside a Container Using Visual Studio Code Remote Containers
Ah that is what you mean, then yeah I agree.
Yes, but I think it's important to note that every other broker I've used presents the information in the same way and the way they are displaying the info is an accurate representation of the state of the account at that moment.

There is a rather large difference between how you do interfaces for people with training who are experts and the amateurs that Robinhood is targeting. It is the difference between a full cockpit and the interface you put on something like Garmin's autolanding system[1].

So, yeah, I'm blaming the interface people at Robinhood because they are targeting a non-broker segment of the population and need to find a way to put that information a broker would give you into the interface. This information includes things like "you do not own this much money" at a minimum. Facts are amazing things, but eventual truth might of save this person.

If you target a group of people, its your responsibility as a UI designer to make sure your interface is actually safe for that group of people.

No, please refer to all the ink spilled on this already. They were very careful to avoid references to paying anything in the app anywhere, or linking to anywhere where payment could be made. This was always the rule previously.

It's not just HEY: other developers are now reporting that Apple's grip is tightening and starting to enforce this change. You can no longer provide access to any service without submitting to Apple's tax, unless (1) you are a "reader" app or (2) you only sell to businesses (i.e., the user cannot pay for the app).
Just show Robin Hood's contact information. It doesn't really matter who picks up the phone.
Couldn't agree more. My primary monitor is a 43" 4k LG at unscaled, native resolution. I can fit five 94 column wide terminals tiled across, each showing 140 lines of text.

Is the text super crisp? Nope. Would I give up all this space for smoother text? Not a chance. Would I replace it with a 43" 8k monitor? In a heartbeat.
Yep! Absolutely true, and one of the reasons why Encrypt-then-MAC is the only generic composition method scheme that always provides certain security properties (specifically, security against chosen-ciphertext attacks given that the "encrypt" part is secure against chosen-plaintext attacks and the "MAC" part is secure against forgeries).
Very true. If Zoom handles the encryption and decryption on their servers, rather than fully on the client's machine, then they can still "listen in". The only way I would trust their E2E is if they can't see or hear what's happening too. It's wild to me that companies I've worked for that have insane privacy and on-prem server requirements, will use Zoom no questions asked.
> All kinds of deaths that have nothing to do with the virus have been reported as "died of COVID" for dubious reasons

This is overstated. SARS-COV2 causes clotting which can lead to cardiac arrest, pulmonary embolism, stroke, and a host of other issues. The medical community tracks most of these as deaths caused by potential complications from the infection because we know it happens, so it's a reasonable precaution.

No doubt the reporting around these numbers is overblown, because, surprise, science reporting in the midst of a panic is even more abysmal than usual.
