I think they are claiming it's less than 51 percent of hashpower - because they can reduce/disable the 51% by attacking some centralised points, including:

- The c20% of nodes that have outdated software could be eliminated
- The c60% of nodes that run on the three ISP's could theoretically be blocked by a nation state if those ISP's could be controlled.

i.e. it might be more like 51% of 30% = 15% of hash power, which are the 4 entities.
Here's a reason to think about trial period rather than very limited functionality free-forever.

I don't know who you are targeting, but I would imagine that the customer sweet spot for you would be the intersection of:
- Traders who are engaged enough and delve deeply enough to need Bloomberg-type data, beyond what is provided by the typical broker pages/Yahoo Finance/SEC/Seeking Alpha/fintwit/newsletters/company disclosures (which are all very low cost or free and sufficient I would think for casual users)
- And yet, who are not professionals with access to the Bloomberg terminal

I suspect that this is a very small but growing group. The characteristics of this group is that they will be careful with money (it comes out of their pocket, not their employer) but if they find a tool that is actually useful and an aid to generating alpha, they have sufficient AUM that it is worthwhile to pay a reasonable monthly fee to access it.

FWIW, I'm not sure how much the uptime during market hours will be critical other than for day traders. Most of the traders in this group will also have day jobs.

This is all very unscientific and not based on data, I'm just going off my experiences and those of others I know who are in a similar boat.

P.S. Unless you're trying to disrupt the Bloomberg terminal itself for professionals, in which case please disregard this entire comment.
Dell went from being the best site for configurable machines in the '00's to the absolute worst on the net less than a decade later. What happened?

Yes, we are significantly less expensive, and focused on providing a massive depth of data on virtually any company you can think of, including raw numbers going back decades.
If you can't distinguish the architecture of Las Vegas style strip malls (and the culture therein) from the neighborhood oriented grids of Manhattan (and its vastly different culture), there's no way to be helpful.
That's a childish take. Here's what the article says are the SEC's actual concerns:

Gary Gensler, the SEC chief, has criticized payment for order flow (PFOF), a practice in which some commission-free brokers generate revenue by sending customer orders to wholesale market makers in return for payments, rather than to exchanges. He has said a ban on the practice is not off the table as it raises potential conflicts of interest, giving brokers incentives to encourage customers to trade more frequently to maximize the payments. The meme stock trading frenzy exposed concerns about the ways in which PFOF increases complexity and potential fragility in the securities markets, the House Financial Services Committee report said. Proponents say PFOF is a major reason brokerages were able to stop charging trading commissions, and retail investors often get a lower, better price than they would on the main exchange.

Gensler has criticized the "gamification of trading" in which commission-free brokerages encourage excessive trading using lights, noises, notifications and other gimmicks to generate more PFOF. He has also highlighted the use of artificial intelligence, predictive data analytics and machine learning to push products. In August 2021, the SEC issued a consultation on potential new rules to limit gamification and other "digital engagement prompts." The agency is expected to proceed with a rule change in the coming months. read more The U.S. House Financial Services Committee on Friday urged Congress to adopt legislation mandating the SEC study how its rules need to change to address new technological developments, such as digital engagement practices and social media-driven market activity.

The GameStop saga highlighted the small number of market-makers -- brokers that execute trades and publicly post buy and sell quotes for others to trade -- that dominate the retail market, which may pose competition issues, Gensler has said. The House Financial Services Committee said that at the time of the Reddit rally, Robinhood was not connected to any exchanges, and of the six market makers Robinhood routed all its customers' orders to, nearly all were unable to execute trades in certain meme stocks due to the market stress.
"Had all these market makers been unable to execute trades, Robinhood would have been unable to execute trades on behalf of its customers," the report said. Nearly all retail trades are executed away from exchanges.
That is partly due to rules that allow market makers to offer fractional sub-penny price improvement on bids and offers, whereas exchanges have to quote in pennies. Gensler has said that has created an uneven playing field in the competition for retail orders.

As an aside, institutional investors, like pension funds, are not trying to generate +500% returns on options or meme stocks. They're not trying to beat traders. They're more comfortable with stable rates of return over the long term. +2%-3% per year. Not hard to beat for a day trader.
> the GP comment claimed upgrading PG was a piece of cake. You claim it is not a piece of cake. So it sounds like you agree that the claim that upgrading PG was a piece of cake was misleading.

GP claimed upgrading was a piece of cake, not that zero downtime upgrades are a piece of cake. The two claims aren’t interchangeable. The simple upgrade path is always available, though it may have downtime consequences you personally are unwilling to accept. And the complex upgrade path is complex for reasons that have nothing to do with PostgreSQL - it’s just as complex to do a zero downtime upgrade in any data store, because in all cases it requires logical replication.

So if anything it feels like you’re the one being misleading by acting as though GP made a more specific claim than they actually did, and insisting that the hard case is hard because of PG instead of difficulty that’s inherent to the zero downtime requirement.
> the retail traders

I have a friend who works in HFT[0][1], over a beer or three in central London a few years ago he told me that in his world a common description of retail trading is "dumb flow".

When your intentions to trade are being sold to the HFTs before your trades are even priced, I guess that does indeed rate you "dumb".

The article:

> The U.S. House Committee on Financial Services on Friday called for the SEC, along with other regulators, to do more to protect the markets from similar events. read more

> The impetus for change came from the so-called "Reddit rally" of January 2021, in which GameStop Corp (GME.N) and other "meme stocks" popular on social media surged to extreme highs on buying from investors trading heavily through Robinhood (HOOD.O) and other commission-free retail brokerages.

> The intense volatility led to big losses for hedge funds that had bet against the meme stocks.

They don't like that the general populace was able to damage hedge funds, so they're making changes to stop it. I don't really know the changes technically, but the intent is right there.
I didn't read the article and I'm deeply upset by this.
Mitigate kill chain distruption in age of electronic warfare.
I think the Surface line serves the "I only want one portable device" crowd well enough, even though I think it could be better. Applications being able to adapt based on the way you're interfacing with them would be the most work required from developers but also probably the best of both worlds... just that'd require Microsoft investing in 3rd party developer support in a way they haven't before.

I personally use both a laptop and an iPad regularly enough in their own contexts that I find it worthwhile to have both.
Unfortunately it's starting to happen here too. I'm not sure how much longer I'll be able to make these arguments at the rate we're privatizing and contracting out things... Might end up just as bad here in the long term.
One of the many reasons to look forward to retirement is to be able say what I really think on LinkedIn.
Sure, that may be the case. It’s just too bad all the unneeded name-calling and insults were part of it.
Your outrage is unwarranted. The proposed changes are:

1) Limiting PFOF because it creates possible conflicts of interest.

2) Limiting "gamification" of trading via engagement prompts.

3) Adding sub-penny prices to exchanges to harmonize them with market makers. This is to encourage more orders to be sent to exchanges instead of market makers.

How are any of these things capitulating to institutional investors?

This holds true for a number of situations where approval is required. For me it's particularly helpful when looking for IT/Information Security approval. "What actions/precautions do you recommend I take, so that you will approve this when you are asked to (and we are implementing a secure solution)?"

Judging by the article I'm not doing terrible at all for someone under 30, despite the fact that I use my phone for continuous glucose monitoring, which means I can't live without it in a nearly literal sense. I can't remember what it was like 3-5 years ago though, it was probably worse, but after reading a few articles about the attention economy I started paying much more attention to what I was doing.

The most terrible thing for me is 2FA, especially at work. If I'm focused on something and I have to open the notifications on my phone in order to complete the demanding task, I'm at high risk of an attention lapse. I wish there was a 2FA app that functioned entirely within the lock screen or even the Always-On Display.
The purpose of LinkedIn is small propaganda, same as Facebook or Twitter. Any other use is mostly drowned out by the posters.
FWIW, I think the comparison with Bloomberg is a bit of a distraction. It seems unlikely that you can live up to that 90% claim, but that doesn’t mean it’s not a good product or good value. It looks like you’re targeting a different market than Bloomberg users. I took a quick look at your site and found the framing there much more compelling than the direct dig at Bloomberg here.

Not a marketer though, so what do I know. Good luck!
That's just color commentary from the author of this piece. If you read the rest of the article, the specific changes proposed by the SEC are outlined.
Funny thing with my printer - I bought a "SAMSUNG Xpress M2026W Mono Laser Printer" for £60 about 4 years ago. Thought this is pretty good - Samsung's the way.

Then HP bought Samsung and killed that model.

Now I see they go for £130+ second hand on ebay.

I think that says something about how the market's going to hell as it were.
I never thought to do this and already enabled it per your comment. Let’s see how it goes the rest of the weekend.

It’s about verifying the word count by looking at the number of pages. Making X pages roughly equal to Y words (or at least characters).

By itself, typeface/font doesn’t matter. But typeface/font, combined with character size and white space rules (indents, line spacing, spaces after commas, etc.) are necessary for word counts to have meaning.

Otherwise, a lawyer could use a very small font, low size, or very little white space to cram more words in the same space.

So really it’s about being able to verify the word count by looking at the paper and not counting the words.

On the plus side, String makes a really good example to explain ownership, moving, stack vs heap, etc. All of which you need at least a basic understanding of to do anything non-trivial in Rust.

I kind of feel like it goes without saying that Rust isn't ideal for beginners. For developers who already have a good knowledge of other languages I feel like learning about these things shouldn't be a problem, as becoming familiar with these concepts is one of the main benefits of learning Rust.
Someone has to draw the lines.

It’s either going to be the representatives which are directly elected by the people or it’s going to be an unelected bureaucrats.

Your solution, being the latter, is far far more undemocratic. The framers of the constitution knew this and that’s why they put redistricting into the hands of the ELECTED BODY.
So this report pretty much disproves all of the assumptions that the meme stock conspiracy theorist have been making:

Robinhood had to disable opening new positions, because they are unable to meet their margin requirements. They only survived, because they were granted a discretionary rebate. Otherwise, the DTCC could have taken control of their entire portfolio, and could have liquidated everything to protect its other member firms.

RH had poor internal practices, and did not fully understand how these margin amounts were calculated, nor had they implemented best practices for modelling those. Additionally, they technological infrastructure had already been at the edge of breaking down under the load for days even before the meme stock event.

Citadel Securities had nothing to do with RH not accepting new buy orders. In fact, they were the only one of RH's six market makers who never asked them to route away orders. The only thing the did negotiate for was a reduction of PFOF rebates, because RH was using its own, non-standard approach for calculating those that resulted in RH receiving a huge increase in rebates.

At the risk of sounding repetitive, this can also be a classic case of ADHD. If you also resonate with the post, ask yourself - do you have issues planning and completing long projects? Time management and procrastination issues? Lacking motivation? (Dis)organization problems? (Bonus: frustrated with yourself/your progress!)

If (like me) you say "damn that's a lot of things I have to a significant degree" then you should

a. read up on executive (dys)function, and

b. Ask your GP/doctor if you may have ADHD*

* - often CPTSD, physical brain trauma etc can also cause similar symptoms, as they can also cause physical changes in the brain similar to ADHD
(There's a lot more of nuance and stuff that can be discussed, I'll try my best if anyone has any questions)

Short selling wasn’t the issue in this case. It was loaning out shares to short that straight up didn’t exist.

> But even so, the gigabyte sins of the hard drive makers are still less than half of those of the network card makers who used to advertise baud instead of bytes,

Actually, they generally specified bits per second, even if they called it "baud".

> so the fact that the data is going across as 5:4 encoding means that you divide the Kbps by 10 - not 8 - to get the actual throughput.

Stop bits and start bits. E.g. a 9600 bit per second v.32 MODEM operated at 2400 baud (2400 4 bit symbols per second), and had an end-user throughput of 960 characters per second.
ARM original operating system: RISC OS still alive after 35 years
NPR's "The Indicator" had a recent episode on this: https://www.npr.org/transcripts/1106468243

Part of it was an explanation of what Payment For Order Flow (PFOF) is. They also had a few short comments by a researcher on the potential conflicts of interest. His opinion was that there are two, and one of them (ensuring customers get a fair price) is solvable but the other (brokerages having an incentive to steer customers toward trades with higher PFOF) is more problematic.

It sounds like the SEC hasn't decided whether to ban PFOF or just require more disclosure about prices, which seems to match up with what that researcher said.

(Also point of trivia from the NPR episode: PFOF was invented by Bernie Madoff.)
It is the story of growing up as a kid, then becoming a smart adult, and then growing old and stupid again condensed to a much shorter time frame. That is why everyone can relate to it in some way.
There was no reason for this to happen. It was an hysterical and opportunistic response by the public health authorities and the teacher's unions.

As the article stated, the schooling of the elites continued uninterrupted during the pandemic. COVID did not spread uncontrolled into those homes.

Children aren't born civilized. It's the duty of families and the schools to civilize them. With the breakdown of the family over the last fifty years, more and more was dropped on the schools. They were supposed to provide education and increasingly many support services.

When COVID struck, that responsibility was mostly abandoned for the lower and middle classes. Our institutions failed, for no good reason. People are trying to pick up the slack, but the way our society has been restructured, with both parents working, makes it very difficult to provide the education and supervision that the children need.
They routinely refuse new accounts if something looks fishy (to them). They don't provide extra information or even accept payment in advance.
Interesting to hear peoples perception of America on here. A lot seems to be based off a short visit or reading online comments of disgruntled Americans. Additionally, some of the issues outlined, such as the gym membership issue, I have never experienced in my entire life nor know anyone who has had that issue.

If you have visited you probably went to one of 3-4 cities or a tourist attraction, neither is really indicative of how most Americans live.
I was a SWE at Bloomberg for a few years. I don't think people appreciate the breadth of the platform; they employ something like six thousand engineers.

What you regard as broad spectrum passion is (in my view) the product of sustained organization, not spontaneous grassroots opposition. Crafted legislation that gets passed and is then (perhaps by design) the subject of a test case is not such an unusual thing.

Consider for example the recent wave of prophylactic legislation forbidding the teaching of 'critical race theory' in k-12 schools, although CRT as such is a kind of structural analysis that has gained adherents among legal sociologists, mostly at the post-grad level. The anti-CRT laws are mostly an attempt to shape school curriculums that mention race by legislative fiat, and provide a cause of action to fire teachers who indoctrinate students with (or perhaps merely expose them to) opinions that are out of step with the popular consensus.

Certainly, this is no overnight process. But a few years ago, people who said Roe was likely to be overturned were dismissed as alarmist. Fringe positions become mainstream by degrees, and those who don't pay attention to them often underestimate the intensity and speed of such changes.

Consider Mark Burns, an ultra-conservative pastor and regular candidate in South Carolina who recently came in second in the Congressional House primary, with 11,000 votes (about 25% of the total). He holds some rather extreme views, and while he lost this time he might continue to improve his electoral standings in future.

Carrying an unwanted child to term sounds a lot like slavery, which sounds like the opposite of personhood. But I guess you’ve built a straw man you don’t believe in so it doesn’t make sense for me to push too much against that.

I guess what I would say in general is that we’re talking a lot about when personhood begins, but I don’t think we’re talking enough about when personhood ends. To me, personhood ends when the government forces you to do something with your body that you don’t want to do. In that moment you are not a person but in fact owned by the government.
Bloombergs data isn't exactly stellar half the time either.
I think the issue is if you want zero-downtime (or close to zero downtime). pg_upgrade can take upwards of 10 minutes to run even for relatively small databases. It can potentially be hours for large ones.

As much as I dislike cryptocurrencies, I do think the whole concept of distributed ledger is/was interesting from a theoretical point of view. There are still several unsolved problems in the field, so I could see some researchers working on them. I wouldn't, cause I don't like the application, but I can see the theoretical appeal.
