Robinhood blamed their DNS system being overloaded last time [1]. Also RH (and other brokers) only show quotes and forward orders with some basic calculations to their exchange partners. They should not be anywhere near the same load as the exchanges. All this points to major architectural problems at the company.

> strict regulations to follow, and the responsibility of safely handling money for millions of people. This should be fixed within days even if it means redesigning the entire system

Somehow, in my mind, the responsibility of safely handling money of millions and redesigning the entire system don't really mix. Ditto for strict regulations and redesigning the entire system.
Your fears are justified but what I am saying is containment won't be very effective. The worst case is if it lingers on barely spreading like it is now. Once you see 100k+ infections per state and every major city with similar numbers things will hopefully normalize.if this timing is close to when Russia and KSA straighten out their dispute I would say that is a good time to start buying slowly.

It really depends on the unknown factors. Things will normalize because people gotta eat, the big unknown here is when. Will everyone start missing mortgage payments and credit card bills because quarantines (unlikely)? Will supply chain issues cause big losses (very likely)? But you can make up for losses,like you said even with quarantine people still order online. We're seeing losses but no cascadig long term collapse like detroit,aig,lehman brothers in '08. But the worsr case can still play out and collapses can start cascading if the corona fears and oil dispute last more than a few weeks
Ah yes, operating systems - file that under "I forget what else".

Like I said, I feel that I overpaid for that education. The degree itself has paid for itself many times over, but I needed to learn basically everything important for a CS career on my own.
Ah, interesting. I think I have some reading to do; there clearly are multiplatform images out there now (Debian for example https://wiki.debian.org/DebianKernel/ARMMP) so my understanding of the situation was somewhat mistaken.
Yes, I also noticed that. I think it should be either "not within -> not easily recognizable" or "within -> easily recognizable".

Vaccine development usually take years even in the best cases.
This old process takes long and needs a lot of ressources. Culturing a virus is slow.

The new vaccine will likely be a protein that provokes an immune reaction to some essential part of the virus and it will be made by more effective means like genetic modification of eg. a pet microbe or yeast.

No egg as a side dish I guess.

I had looked at their job board to see their technologies and saw heavy use of python. I know large systems can be built in python, but for financial services something more performant and safe probably would have been better. But who knows, maybe Robinhood would never have had the adoption its had thus far if it chose something else.
Ship of Theseus is a great argument for crediting the original author, even if it's been 100% re-written over time: The ship would have started from one (or more) expert ship builders, while the continual patching could be done by comparatively-unskilled hands.

(Not that this is the case in software, but merely saying that that parable would lend itself to an easy answer as to whether to credit the original or not.)
The pandemic is bursting the bubble, it's not the underlying cause of the problem. The conditions have been building for several years.

In 2001, the bubble was burst finally by big shift in interest rates from the Fed, and some insane valuations which cause the smart money to run, causing a stampede.

Most analysts have been raising red flags for a long time now. The market has been operating on hype and irrational good vibes for at least a few years.

Warren Buffet started hoarding cash some time ago - long before the Coronavirus.

Listen to Robert Shiller's interview earlier this year on the FT concerning 'narratives'. I don't think it's a new concept, rather just a modern articulation of it. The mania we're seeing is just a more extreme form of narrative.

It’s the latter.

The coronavirus is also responsible for SARS and MERS. They had good luck with a vaccine for SARS but it wasn’t needed anymore so they stopped. MERS is highly lethal and was something they wanted a vaccine for if it popped back up. Ideally (this is where my knowledge stops) the vaccines they were working on for other strains will be a good launching pad to make a vaccine for COVID-19.
The last time there was a banana disease that wiped out the Gros Michael, we ended up finding an (admittedly subpar) replacement quickly enough. With the amount of commercial demand behind bananas, once the disease makes its way through south and central American banana fields, we'll find another replacement.
I see little reason to think this virus will infect 30-60% of the world's population.

It has infected <0.1% of South Korea's population and the number of new cases per day has been going down for several days in a row now. Today they reported less than a hundred new cases.

It sure doesn't seem to be sweeping through the South Korea population like wildfire. It doesn't appear they will even reach 1% infected, let alone 30-60%.

It also doesn't look to be on a path to infecting 30-60% of China's population. New infections in China have dwindled to almost nothing, and the total number of cases there is less than 1/10,000th of their population. (Even if one is skeptical about China's official count, it's preposterous to think they've undercounted by tens or hundreds of millions.)
Just start a monthly savings agreement. Presumably you've barely put in any signifncant part of your assets. You're much better off than someone who has $400k in the market and might need it soon.

In fact, starting your investment career during a 15% drop is great to inoculate you against panicking in volatile times.
Yes, that's also what I said in my original comment.

Working from Home – Lessons Learned over 20 Years and Shopping List
People don't usually invest their entire life assets at a singular point in time. Share purchases are made per paycheck (e.g., 401k) over a working career. In practice, no retail investor experienced what you described.
My employer would rather pay 120% of Nowhereville for a dev in the eastern standard time zone than pay an Indian salary for that exact same dev working in India. And they'd even rather pay 120% of east coast major metro salary for that same dev commuting to their major metro office at least a few days a week.

I get the impression that much of the non-core software dev has already been sent to India. Much of what's left is core to the business and highly speed/quality sensitive, less price sensitive. Some of it even got offshored then reshored when management realized that time/language/culture/etc issues impose a variety of real costs that may or may not be acceptable depending on the project.

> “Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray’s case, physics. In mine, show business.

Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the “wet streets cause rain” stories. Paper’s full of them.

Very useful. Many problems are more easily represented as fuzzy sets or fuzzy relations than in other terms. It's particularly good at encoding linguistic variables, such as "very fast", "too cold", "accelerate hard" and so on in a way that it can smoothly overlap them.

It's also useful for encoding uncertainties that are not yet mutually exclusive. There are other logics too (eg Dempster-Shafer evidence theory), often grouped together as "monotone measures".
unfortunately that's totally true. i think IRGC is using it as a bio-terrorism weapon against west. also i think ISIS and terrorist like them will try spreading covid19 to kill people.
Do you have other numbers?

The last Clojure survey has ~2500 people responding. Which is basically the same for several years now. I we assume that 10 times more people are actively using Clojure, then that would be 25000. Still a lot less than the probably 7 million Java programmers and 8 million Python developers. https://www.zdnet.com/article/programming-languages-python-d...
That sounds unusual since smoking in China seems ubiquitous.

If you really want to understand what's going on with CV19 you can try reading the pre-print papers posted at www.reddit.com/r/COVID19 which is a heavily moderated science-focused sub. The analyses posted by users down thread often contain links to even more recent source data.

I've learned an enormous amount there (and also how inaccurate media headlines can be in a complex, rapidly-evolving situation like this).

This a class of objects that look differently depending on the direction from which you look at it. Its shape is easily recognizable when looked at from the side, but when looking directly at the bean is just a point source of radiation.

Thus, while it is more luminous when looking at the bean, it may s easier than identify when looked at from the side.

Imagine looking at flashlight at nighttime. The flashlight is bright when looking at it directly but then it is difficult to tell what kind of light source it is exactly. Tilt it a little and it becomes less bright but more recognizable.
Is any retailer going to actually be willing to trust amazon though? And what if it doesn't work and the customer ends up not paying - is amazon also taking on the liability for that?
Right now I am trying to rid my business of Wells Fargo. They are charging us $700 / month for services that would cost me around $200 from PNC. Their pricing is so convoluted that it is impossible to understand, and their reps take advantage of that. They quoted me an estimate of an additional $60 / month to add positive pay verification for checks, but my bill went up $300. And just to add insult to injury, they charge $1 for every time I need to run a search on our account records. Oh and I amlmost forgot to add, I was locked out of our account for a few days because of a rule change. I made the mistake of using them out of convenience because my personal account is with them. Don't make the same mistake as me. When you start a business avoid Wells Fargo like the plague.
I noticed this smoker effect early on! Data from China was showing about 20% of the infected population was smokers, while smoking is closer to 60% in Chinese men (by cursory google search). The death rates were much higher for infected smokers, but they were curiously underrepresented.

This has a really interesting double effect if you think about it. In places with lots of smokers, fewer people will get the disease, but a larger proportion will die from it. Both of those effects will magnify the death rate.

Edit: assuming the protection is additive and not proportional to existing rates across ages
> Broken! HaHa!

I think this is about equivalent to the error messages one already gets from a typical Clojure REPL session, so no loss of potentially useful information, after all.
It is physically possible to manufacture things outside of China. Which is why higher prices are necessary -- it costs more to do that, but we want it to happen so that the supply increases.

The lead time to start manufacturing simple products like masks isn't that long. That puts a time limit on the high prices -- even if the demand stays high, supply catches up to it. (Compare this to, say, housing where increasing supply is constrained by zoning which prevents supply from increasing in response to demand.)
At the very least wouldn't inflation cause an upward trend even if small?

In what way is Elliot "Trump-allied"? He seems like the kind of institutional conservative investor that would hate Trump's attempts at, essentially, implementing a Neo-merchantilist trade and financial policy.
> It's quite an easy assertion to make, that US military acquisitions are rife with inefficiencies, but solving that problem is much harder.

My favorite example of this was the US Army's decision to use the ACU design pattern. The only thing it blends in with is Gramma's floral couch.

In terms of ships and other equipment, having a commercial manufacturer step into the military space would be like asking Ford or GMC to make Bradley Fighting Vehicles; they don't have the know-how for combat ready manufacturing. The systems in any combat vehicle are an order of magnitude more complex than commercial offerings in terms of design, verification, and manufacturing.

Part of this is the military requirement for 3rd party integrations. The BFV is manufactured by BAE Systems, but the turret optics/electronics package is Raytheon.

An engineering firm I'm familiar with recently got the contract for part of the M1 Abrams tier 4 (?not sure?) upgrades and has to meet integration requirements of existing hardware/electronics and new hardware/electronics other bid winners are contributing.

I would argue that, aside from the run-of-the-mill pocket lining (see ACU design selection), the acquisition process for military equipment is necessarily inefficient.
> but please explain the injustice of foreclosing on someone who isn’t paying their mortgage

You can read more about the fraud here[1] but in short Wells Fargo (and others) wrongfully foreclosed on homes that were owned by someone who:

- was not in default. i.e., They were, in fact, paying their mortgage or in some cases had even completely paid it off.

- was entitled to protection under the Servicemembers Civil Relief Act. Most often, active duty military personnel stationed overseas.

- was entitled to foreclosure protection under federal bankruptcy laws.

- had entered into a written modification agreement with the bank and had been abiding by the terms of that agreement.

- was wrongfully denied a mortgage modification or requested a mortgage modification and received no response.

In addition, there were many cases where the institution had an obligation to engage in loss mitigation efforts with the borrower (modification, short-sale, cash-for-keys, etc.) and failed to do so.

> In Just Walk Out-enabled stores, shoppers enter the store using a credit card. They don't need to download an app or create an Amazon account.

But you may as well. By giving them a CC# you're allowing Amazon to spy on you anyway -- and that's not even mentioning the copious surveillance in such stores in the form of cameras and behavior detection.

> If shoppers need a receipt, they can visit a kiosk in the store and enter their email address.

Oh, and if you want a receipt, you'll have to give Amazon your email address, too, which allows them to more easily tie your real-world identity and activity to the profile they already have on you.

This sort of thing is a privacy disaster. I wouldn't set foot inside a store that does this.
How is it wasting their time. Would you be just as offended if he said "I wish you well" instead? You're just being intolerant toward others beliefs and you think you are any less bigoted because your beliefs are better. He didn't force anything on anyone. You might be ignorant about this but people who believe in prayer don't think of it as hoping or good wishes, they (we) genuinely believe it has actual immediate effect. Your lack of belief does not justify your intolerance, he did not force others to participate. You are free to do more interesting things while he spends what...30 secs doing something you don't believe in? Such a high price for tolerance?

I think this is something of a strawman: there are plenty of million line (plus) systems and software suites, but I think million line programs are relatively uncommon by comparison.

Especially so if you don't count library code, and I don't because otherwise you end up doing things like counting the number of lines of code that back the Win32 APIs in your program line count, which doesn't seem sensible. Most of the time we treat libraries as black boxes, except on rare occasions, so don't tend to think of them as part of "our" codebase[1].

Most million line plus systems are broken down into subsystems (applications, services, libraries, etc.) that in isolation are smaller, and in many cases much smaller.

Even with those rare million line of code monoliths, for the most part there's some level of organisation in the codebase: layers, subsystems, components, or a mixture of these and whatever else is appropriate.

This organisation, and particularly when coupled with modern tooling, facilitates the understanding of even very large systems.

I don't say that it's necessarily easy but, then again, neither is understanding a large, complex system implemented in K.

[1] Except when thinking about security because third party code has been shown to be a rich source of vulnerabilities.
Your last sentence is filled with so many factual errors...

The B2 is considered the most stealthy of any of the fifth generation aircraft currently flying. And it carries a 40K payload. Yes, that's smaller than the B-52 and B-1, but it's fine for it's role.
I'm about ready to throttle the next "it's just a flu" person I read. It's real; it's serious and we should be taking rational actions to mitigate and contain it. Don't go to events, avoid restaurants, bars, gyms. Work from home if you can. Have a supply of food for home.

In some of the worst hit areas of Italy, it looks like they're already triaging people or considering it.
> You could say Bayesian statistics is a subset of Fuzzy logic.

Arguably not. Mathematicians have teased out differences between different many-valued logics and systems. A critical one between probability and fuzziness is that probability includes the axiom of the excluded middle and fuzziness does not. In probability the values of mutually exclusive events must sum to 1.0, in fuzziness they need not, because it doesn't require events to be mutually exclusive in the sense that probability requires.
Using outside investment to buy back shares is a way to transfer ownership to the outside investors, so long as the investors hold their shares.
So it is not a click-bait title, they are actually asking the question.
I used Dash pretty extensively in 2018 (so bear in mind things have changed some since then).

It's a great tool but has some downsides compared to using d3, a chart library or even PlotlyJS directly.

* There is no good path to invert Dash and Flask relationship so that you can embed Dashboards into the larger context of a Flask application. Which really limits it for single standalone dashboards.

* The JSON serialization and dash components are hard to extend or customize as an end-user (without making changes to the library directly). So you'll quickly run into a barrier when extending for anything custom.

So it's a great tool, you can build responsive dashboards (that work with great Python libs such as Pandas for the processing) very quickly, but IMO its not suitable for embedding dashboards into other applications (which TBF isn't their goal).
Oh yeah totally agreed there.

I do worry that this extends to a sort of class situation where folks again with fewer resources are at a disadvantage as for them they have to go out damn far most places to even start thinking about a home.
