Honestly, I feel like that about IoT in general. Cheaply made, internet-connected consumer products that will likely not get patched for security issues? Sounds like a nightmare.

Makes me wonder, are there any efforts to standardize IoT protocols and security best practices?
- The vast majority of products you create are never actually employed to do anything and are instead thrown into a blender to make science-goo, arbitrary amounts of which are required to unlock new stuff that is also mostly destined for the blender.

- Bots are introduced way too late in the game, forcing the player to manage the rapidly increasing complexity of their infrastructure manually for a large portion of it.

- Power distribution is a tedious non-problem you're forced to keep solving, again manually most of the time because bots come so late in the game.

To name a few. The natural argument here is that those things are required to motivate the player to make their automation faster and more efficient to progress the game, but the point is that they feel needlessly arbitrary. In a game like Subnautica, for instance, there are some big high-resource things you have to build with reasonably deep critical paths, but they are things you actually use instead of just melting them down to increase a number somewhere. They feel necessary, science-slurry doesn't.

Players also claim that yeah, that's all true, but the real game doesn't start until after you've researched everything and launched your first rocket anyway. Meaning all of that is essentially a 40 hour tutorial.
What does the word performant mean exactly?
Nice but the page looks like it's old and somewhat stale.
I don't think anyone is saying "we don't need to investigate". They're saying "let's find evidence before we assume malintent".
> When I had FB, most of the ads were for products (or services) from small businesses.

What makes you think the quantity of quality of advertising on Facebook is going to change? They still have:

- Your location

- A list of what you post about, what you link, what photos you've shared, what activities you've attended, what groups you are in, etc etc.

- All of the above about many of you friends and family members just in case there are interests you don't talk about on Facebook.

So how exactly is whether Facebooking that I checked the weather on the corner of 3rd and Center at 7pm going to help those small businesses advertising on Facebook?

Is there going to be some flash umbrella store around the corner if rain is in the forecast?

Certainly the spread of COVID19 in the UK and US is evidence that something can spread with the encouragement of "non-consensus outsiders".
I'm with you on this, I just built a (much more modest than the article's) workstation/homelab machine a few months ago, to replace my previous one which was going on 10 years old and showing its age.

There's some folks in /r/homelab who are into this kind of thing, and I used their advice a fair bit in my build. While it is kind of mixed (there's a lot of people who build pi clusters as their homelab), there's still plenty of people who buy decommissioned "enterprise" hardware and make monstrous-for-home-use things.
There's an important difference between "stay in your lane" and "keep your mouth shut until you know what you're talking about".
Who owns the tests? Developers.
Oh, yeah I know. It's just tricky to keep that in mind sometimes.
Reminds me of the Solid-State Drive checkbox that VirtualBox has for any VM disks. Checking it will make sure that the VM hardware emulation doesn't wait for the filesystem journal to be written, which would normally be advisable with spinning disks.
Everybody here correctly divined what you mention, and then could confirm it after other trading apps went on to actually shed some light towards what's going on.

My point is exactly the shitty comms of Robin Hood - they were the first to make this move, they gave no reasonable explanation. It doesn't matter what we know now. What matters is that RH's users didn't know then.
I meant "underlying conditions", not underlying symptoms... that's my fault.

So, basically, if you are healthy, your chances are absolutely tiny that you will die if you catch it.

So, yeah, it matters a whole lot actually.

I thought the same when I bought a bunch in 2014. I held for years and didn't make any money (maybe a little from BTC increases?). You could buy some and hold and check the price every waking hour for the next few years waiting for another pump where you can 2x your investment, or you could move on with your life and not got get sucked into stupid fantasy money making schemes.
"The company reportedly said that Google’s policies explicitly prohibit reviews aiming to manipulate an app’s rating"

Literally the only reason someone rates something is to affect/manipulate the rating.
I am reminded of the entertaining DEF CON talk I watched a while back with the awesome title, "Adventures In Smart Buttplug Penetration Testing."
> I tested various fio options, but didn't notice this one - I'll check it out! It might explain why I still kept seeing lots of interrupts raised even though I had enabled the I/O completion polling instead, with io_uring's --hipri option.

I think that should be independent.

> edit: I ran a quick test with various IO batch sizes and it didn't make a difference - I guess because thanks to using io_uring, my bottleneck is not in IO submission, but deeper in the block IO stack...

It probably won't get you drastically higher speeds in an isolated test - but it should help reduce CPU overhead. E.g. on one of my SSDs
fio --ioengine io_uring --rw randread --filesize 50GB --invalidate=0 --name=test --direct=1 --bs=4k --numjobs=1 --registerfiles --fixedbufs --gtod_reduce=1 --iodepth 48
uses about 25% more CPU than when I add --iodepth_batch_submit=0 --iodepth_batch_complete_max=0. But the resulting iops are nearly the same as long as there are enough cycles available.

This is via filesystem, so ymmv, but the mechanism should be mostly independent.
This is absolutely perfect.
Sorry, it says nothing of the sort. All the evidence, including government statistics, tell is it is precisely that, a dismissably small number outside known vulnerable groups.
Yep, I enabled the "numa-like-awareness" in BIOS and ran a few quick tests to see whether the NUMA-aware scheduler/NUMA balancing would do the right thing and migrate processes closer to their memory over time, but didn't notice any benefit. But yep I haven't manually locked down the execution and memory placement yet. This placement may well explain why I saw some ~5% throughput fluctuations only if killing & restarting fio and not while the same test was running.

> Why do market makers buy stock for delta hedging? How do they figure out how much stock to buy?

From https://www.bloomberg.com/opinion/articles/2021-01-25/the-ga...:

The market maker has sold you an option that goes up in value as the stock goes up. The more the stock goes up, the more the market maker owes you. It hedges this by buying something else that goes up in value as the stock goes up—specifically, stock. Its option pricing model—the Black-Scholes formula or a related model—tellsit how much stock to buy; that output is a number called “delta” and ordinarily expressed as a percentage. Delta is the sensitivity of the option price to the stock price; the higher the delta, the more the option behaves like stock. The more in-the-money the option—for a call option, the higher the stock price is relative to the strike price—the higher the delta will be. A loose, nontechnical, incorrect but still sometimes helpful way to think about delta is as “the probability that an option will end up in the money.” A 100-delta option is so far in the money that it is sure to convert into stock, so it's just stock. A 0-delta option is so far out of the money that it can’t possibly convert into stock, so it’s just worthless. A 50-delta option is roughly at-the-money—a $50-strike call when the stock is trading at $50—and could go either way. The more stock-like an option is, the more stock the market maker will buy to hedge it. Here,Bloomberg’s OV page computes a 37.57% delta for the Jan. 29 $50 call as of last Tuesday; I rounded up for ease of use.

If you are remotely interested in these kinds of things I can heartily recommend reading Matt Levine (https://www.bloomberg.com/opinion/authors/ARbTQlRLRjE/matthe...). He's at the same time educating and entertaining and what is more leaves out all the bile and negativity that is connected to these topics in other places. Gamestop is covered in recent issues.

Except you misunderstand one important part in the system, and that is credit drives the wheel of growth. Cryptocurrencies, while transactions settle much faster, are designed around a "hard-money" ideology. You know what's worse than inflation? Deflation. Now, there are pushes for credit in the cryptocurrency world, but as of now, it doesn't seem widespread.

Of course credit systems have their own problems, like debt growing so large that it's impossible to pay back. But usually a nice reset does wonders.

Since credit systems and money is created by governments, they have the power to do such resets and have done so in the past many times in the last 5000+ years.

If the credit systems collapse into a cryptocurrency hard money world, there will be a new emergence of desperate people, slavery, and war.

> Do people not take Walmart seriously?

I tend to think that they mostly sell cheap crap, that even their brand-name stuff has been renegotiated with the manufacturer so they can sell you a lower quality version in order to have the lowest price. They have definitely done this with some products, and at least attempted it on others.

So yeah, their pricing definitely affects my perception of their products. I avoid Walmart.

Office 365 has the clout of Microsoft behind it. I don't know that the general rule applies as well as it does to some new SaaS company I have never heard of before.
The $30k price is interesting, given that it's multiples of what established manufacturers are charging for electric dirtbikes with multiples of power, kWh, performance, and design maturity. The time in the electric motorcycle market where this would succeed is passing. Established motorcycle manufacturers appear to have been watching all of the upstarts establish distribution and supply chain paths before they commit to the e-motorcycle market. A few are beginning to move in, mostly offroad, but some onroad as well. Harley comes to mind, plus a scattering of moped-level bikes. It'll be interesting to see how Sondors, Cake, Zero, and others play out when an 800 pound gorilla like Honda hits their market with serious intent.
IIRC the argument was "we can't say it works because we have no relevant tests at all". That's what I remember from March, but I may be misremembering.
Kinda dumb though. Isn't the point of an "alpha" to release something before it is stable? Otherwise it's just called a release. You can have a rapid release schedule and still release stable software.

I was around 58 when my thumb started giving me problems. As time passed i had other symptoms; hand tremors, restless sleep, muscle weakness, cognitive decline, voice spasm, stiff achy right arm and ankle. At 60 i was diagnose of PARKINSONS DISEASE, i was on Carbidopa and Pramipexole for two years, they helped alot but not for long. As the disease progressed my symptoms worsened, with my neurologist guidance i started on natural alternative PARKINSONS DISEASE treatment from M.H.C. (Mayaka Natural Clinic), the treatment worked very effectively, my severe symptoms simply vanished, i feel better now than I have ever felt and i can feel my strength again. Visit ww w. mayakanaturalclinic. c om. c om. My neurologist was very open when looking at alternative medicines and procedures, this alternative parkinson disease treatment is a breakthrough.
After my Parkinson's Disease diagnosis, my primary care provider introduced me to Mayaka Natural Clinic and their PD Formula protocol, the herbal treatment has made a tremendous difference for me. My symptoms including numbness and muscle weakness all disappeared after the treatment plan! Their website is w w w. mayakanaturalclinic. c o m

Create a two-column two-language ebook reader of free and public domain works that happen to be available in translation, therefore in two languages. You could use volunteers or AI to sync up the two columns. Good for learning languages, you can buy such books of course, but having a massive pile of them in open source available free so you could choose a text that interested you, would be nice. Might be possible to do this for news stories too, now I think about it.

Might take very little "AI" or volunteer work, given that translators don't often break up sentences.

You know what pages I'd like to be fast and performant on github? The PR discussion and diff page. When a PR gets really large (thousands of LOCs and hundreds of comments) (yes I know it's bad to do that, that doesn't help me a lot when it happens), despite them hiding everything so you need dozens of clicks in order to be able to actually read and search through it's slow as hell and it's a mess.

This is not helped by some really counter-productive events being logged interspersed with discussions e.g. any time a label is updated, that's a new line in the discussions log. Is that useful? Almost never! I can't remember wondering "wow when was this PR marked as E-Easy?" It could be useful to have a unified history of all events on the PR in a separate tab, which would include things like comment editions properly positioned in the PR timeline (instead of each comment having its own little history) for PR forensics, but the current version is just inconvenient.

Talking about, having a FAYT which can actually search through the diffs without having to first go through the entire page, find which files are not shown and forcing them to load would be super useful.

An other fun performance crater while I'm at it: when you try to create a PR github target the "default" branch. Always. Period. When you work on a project with a "long and storied" history and you're trying to do something on an old branch, or the default branch is not the development head and you're trying to create a PR to that, it will try to diff two essentially unrelated branches, take tens of seconds to create a gigantic (and completely unnecessary) log and diff, timeout half the time, and it's all for nothing, it'd be more useful to immediately give me a dropdown letting me select a target branch.

Point #3 doesn't seem consistent with the idea that this is just a "stay in your lane" attitude. "Lurk before you leap" might be a better phrase. You've got to do at least a little homework before you can understand a technical topic well enough to make sense of what you're reading.

I am less familiar with finance, but I see this all the time when HN discusses legal matters. The conversation is almost pure noise, because it's dominated by people who have so little knowledge of the topic in question that they don't even recognize a term of art when they're seeing one. Which, in turn, engenders fundamental misunderstandings, and so the whole conversation ends up being a sort of large-scale trainer battle at the gym that specializes in strawman-type Pokémon.

Imagine if a discussion of programming were dominated by non-programmers who are seemingly willfully ignorant that, in the context, the word "functional" does not mean "designed to be practical and useful, rather than attractive."

Thanks for the link. Anecdotally in our hospital only one patient to my knowledge has survived after a higher dose of dexamethasone (this was only used after the patient was worsening despite the standard 10 days of 6 mg dexamethasone). Whether this helped them or they were going to improve despite can't be known.

I would also be careful about how you use the term atypical, in fact most patients with COVID are typical and improve with the standard treatment. :)
I'm not spending the time to watch some Youtube video you're posting, especially if you don't link to a specific timestamp/context. I highly suspect that the link you're saying is that a broker would be responsible to cover loses on trades they made if the clearing house does not; not that the brokerage is required to accept unlimited risk just because someone wants them too.

> But that is Robinhood's liquidity issue and not does justify Robinhood disabling cash accounts from buying stocks.

Robinhood having a liquidity issue 100% justifies them not offering services that they may not be able to actually cover. Because the alternative is way, way worse. You want Robinhood to just... make up money that they owe people but don't actually have? I'm fairly confident that financial institutions can't just make up numbers in order to manipulate their way into compliance.

I very much dislike Robinhood as a company, but what you're suggesting doesn't make sense.

I would avoid at all costs exposing the database to the public internet, even with IP whitelisting.

Make the apps/users connect to a VPN (wireguard or openvpn, setup on a seperate EC2/droplet). Then on the database server only allow connections from the internal IP of the VPN server.

Ideally the database is in a private subnet in the VPC (can't accessed directly from the outside at all) and the VPN server is a public subnet with an Elastic (static) IP. That is how to set it up on AWS anyway, I am not sure the DO networking equivalents off the top of my head.
