Nice article.

Is anyone else getting a "[Math Processing Error]" in red at a bunch of places?

I'm seeing:
>For example, [Math Processing Error], so multiplying by an integer "preserves" this lattice (on the Division section).

This one is even worse:
>The relevant fact about logarithms is that [Math Processing Error], meaning that the problem of multiplying [Math Processing Error] and [Math Processing Error] can be reduced to the problem of adding their logarithms. (in the Everything is Addition section)
Unless your page is google.com, where more time spent on page means the experience is worse, not better.
I really hope an analytic genius can come up with a technique (like differential privacy, but I'm no expert here) that would give advertisers what they want (unique visitor counts, and very few other metrics) to place ads on sites, yet doesn't give away too much privacy, nor leads to enslavement under a single central entity. I guess if something like that doesn't come along, then only old school content-based ads (site sponsoring) without any tracking can be considered ethical (or no-ads of course). The argument against content-based ads was always that it doesn't suffice to finance even web hosting let alone content production. But with ad prices going to the bottom, I wonder if the figures still add up in favour of targetted ads today.
Dang, really? I think this sounds like fun! I would totally work on something like this. It doesn’t seem sad at all, to me. Lighten up!

>plain old negligence from the lawsuits that specifically go after immunity carve-outs in the PLCAA.

Negligence is a cause of action based on elements of duty and breach of said duty. So the question becomes what was the duty of the manufacture and how was said duty breach (the theory of the claim is very fact specific, there isn't really a "plain old negligence" theory). You are right about the proximate cause, that is another element of negligence claims that must be proven, meaning there must be a proximate cause between the breach of the duty and the damages...meaning there could be a duty and even a breach of said duty, but no liability because the breach was not the proximate cause of the damages (this really gets into the weeds of case law).

>The tech industry must have better lobbyists than the gun industry.

Its not about the quality of the lobbyists, NRA and big tech likely use the very same lobbyists, its about spend.
Because of the proliferation of mass shootings almost every knows about the NRA and pro gun rights groups, meanwhile almost no one knows about big tech lobbying, and they might be surprised to learn how much big tech outspends NRA/gun rights...big tech spent $500M in the last decade lobbying.

Context is important, and it's one metric amongst others that should be used.

The point is, there are clearly actionable points GA can offer. It's disingenuous to think there are not.
JavaScript Math.random() should never be used for UUID generation. You will get collisions even at small scale.

window.crypto.getRandomValues() should be used instead.

The quality and seeding of Math.random() is implementation-dependent and not generally good enough everywhere to prevent collisions. Many seed with the just the system time.

Source: I have personally seen such collisions in a production web app with 700k users. A Web search for “Javacsript GUID collision” shows that many others have as well. We switched to the cryptographic generator and the collisions disappeared.
So if I go to the police and give a statement to the effect of "whack assaulted me in an alley!" you're okay with a system where I don't have to substantiate that complaint any further or hand over my phone (to determine whether we were on a date, flirting, sexting, or I had sole motive to fabricate an allegation), but you can be interrogated, your electronic devices confiscated and searched, your friends and relatives called and interviewed, all based on an allegation I refused to provide information for?

As a general rule, the proponent of a claim bears the burden of proving it. This general rule is even more important in the context of criminal allegations. I don't think there should be an exception just because of the sexes of the complaining witness and the subject of the complaint.

Which is the same as my example.

Legal recourse for your bank to lock down your account is actually very limited. But I agree that banks are at least more competitive so they're less likely.

If there were two banks (a duo culture, like google/apple in phones) then you can be very sure it would be the same.

My company switched to Fathom from GA about 4 days ago.

We build privacy software so it felt slightly hypocritical to use a privacy-intrusive service like GA. So far so good.

Good job Fathom team :)
I assume you would get another result running all CLBG algorithms and comparing the geometric means. I also run benchmarks including (hashed) table/field access and was virtually as fast as the same program when compiled natively, see https://github.com/rochus-keller/Oberon/blob/master/testcase.... Of course there are parts where LuaJIT 2.0 is slower than native, but there are also some opposite cases.

Except for possibly commodities what is the purpose of these options. So far as I can tell it’s just gambling. Guessing whether a stock price will be slightly higher in a few weeks isn’t investing. These people aren’t doing due diligence and reading through prospectuses and understanding the proper value of the companies. They are just reading r/wallstreetbets and literally gambling on popular stocks. How does this do anybody any good? It just produces a few people who get massively lucky and a lot of people who lose everything. Neither one deserves their outcome and we are all worse off for it.

About 10 years ago HSBC got caught helping drug cartels launder money and they got massively fined for it. In the subsequent years they made it really difficult to open an account, but they wouldn't tell people what the hold up was because it's illegal for UK banks to tell customers that they are performing an anti money laundering investigation.

That's an interesting analysis.

That directive is usually understood to be about reverse engineering in order to build compatible software: "to obtain the necessary information to achieve the interoperability of an independently created program with other programs" being a key bit.

It's not immediately clear to me - a programmer but not a lawyer - that this has any bearing on whether linking creates a derivative work.

Have any other experts, or courts, weighed in on whether this analysis is sound?

I couldn’t agree more with this. A 49” 5120x1440 curved monitor is brilliant for productivity. It’s better than two or three separate monitors. I do miss high DPI but I wouldn’t trade this type of monitor for the current batch of smaller high DPI ones.

There’s only two or three things that would make this better. A high DPI variant, more vertical space and a greater refresh rate. Given those two things, I think that’s the endgame for monitors (in a productivity context).

(I think that’s 8x the bandwidth so it’s a while away!)
It's the opposite of a strawman version of results-oriented thinking which says that, for instance, 64/16 = 4 is a good result even if it was obtained by crossing out and cancelling the two 6's giving 4/1 = 4.

Result-oriented thinking has to include some reflection about whether results are being obtained in a way that is repeatable or will work in other situations.

The Apollo 11 lunar ranging experiment at the Lick Observatory [pdf]
Summary:

1. Make a project

2. Work super hard at it but not to the point of exhaustion (stay optimal/healthy)

3. If you aren't already, become a good programmer yourself (you really need this, if I'm reading the author correctly)

4. Test your code

5. Be capable of dealing with anger, frustration and joy

6. Your biggest issue isn't time, it's your motivation

7. Dare to fail

So basically: build a project and talk to people. He writes about it epic/coach-like way (e.g. "Fail hard. Fail with motherfucking gusto. Succeeding, like flying, is throwing yourself to the ground and missing.").

I might need to become good at getting people to work on my project, as I might need to split my codebase in 2 and I would like your input on how to go about it [1].

There's a strange point that is made on page 771. Toward the bottom of the page, it says:

Such a conclusion would be wrong.²

The "conclusion" being that doctors want to minimize both false positives and false negatives.

The footnote is:

²In one study (4) of 14,867 films for signs of tuberculosis, 1,216 positive readings turned out to be clinically negative; only 24 negative readings proved clinically active, a ratio of 50 to 1.

Can someone explain to me why the ratio matters? Surely the ratio would also depend on the actual incidence of tuberculosis in the population, and would not be determined solely by doctors' choices, right?

I am not a lawyer but I hold 6 patents With others pending.

Yes, one can definitely file ones own patent. One can also build ones own mansion. Are you interested in building your own mansion? Have you practiced building your own mansion before?

FYI, patents do not prevent someone from copying your idea. They merely give you the right to litigate. If you can’t afford a patent attorney then you can’t afford to litigate. Therefore, what is the value of your patent?

Some patents have value outside granting you the right to litigate. I’m some cases, they are a marketing tool “wow they must have great tech, it’s patented”. Sometimes it’s an asset “big Corp wants to buy me and they already have complimentary patents and they can afford to litigate. They would love to own my patent.”

I would suggest you think deeply on what your goals are and explore cost benefit of filing a patent.

FYI, if you only care about us coverage, you can file a provisional patent for about $80 and it is super informal. A provisional allows you to stake your claimed date without prosecuting the patent and spending money. It give you 18 months to figure out if you idea I’d worth patenting. But be careful, anything not covered in the provisional does not get to claim the date of provisional if added to the non-provisional filing.
Yeah, that's correct. Initially I thought that you can control html on the parked domain.

1. Never did spend more than a few minutes at a time, but have recruiters reaching out on the regular.

2. This is not a LinkedIn skill. I speak at industry conferences regularly through relationships I've built entirely outside of LinkedIn.

3. Conference speaking does this for me.

4. This isn't even tangentially relayed to LinkedIn.

My first job out of college was from a bunch of cold applications. Since then, I've gotten all my roles by reaching out to people (outside of LinkedIn) to connect, and through my network. The skills you highlight as important are not exclusive to, or necessarily learnable on LinkedIn.
I’m not sure I see your logic here. Do you think the payment networks will be cheaper to operate if they’re run by the government? Or would you prefer an actual tax to the fees you’re comparing to taxes? Do you expect banks would drop their transaction fees? Do you think payment gateways would drop their fees? Do you think payment terminals would become free, and their networks free to use?
I'm not doubting that it looks like what you say for the area you looked at. I just wanted to make a more general point that it is not sufficient to look at f'/f and conclude that things will be fine if that is tending towards zero.

I'm not claiming that is what you were saying, I just wanted to call out this point in case other people read this that may come to this conclusion.

FWIW, the solution to f'/f = exp(-t) is f(t)=c*exp(-exp(t)), which actually looks like an epidemiological curve, but like any sigmoid it will be hard to determine the actual saturation point until after it has already passed the inflection point.

Had this debate when we bought monitors for the firm. Some in management said high DPI, good color etc. are not worth the money (which you clarify is what your really mean). But after splurging, the effect on productivity was measurable. If you pay someone to stare at a box for 8h, a nicer box pays for itself pretty quickly.

The article is deliberately opinionated but I basically agree: the experience of editing text on a 4k/Retina screen is vastly superior to what it was like previously and I'd never want to go back.

It's clear that many of the people who think they disagree are Linux users who have (for good reasons) not yet had a period of time to try it out with good OS support. At least, not on their laptop screens. I really hope good Linux support for laptops with high DPI displays emerges, if it has not already (I've read mixed reports).

That's what you get when you put fairly incompetent people in positions of power because they align with your political views.

It’s the opposite for me, having fewer monitors makes it harder to find a window. I have to go through alt-tabbing slowly to get to the one I’m after.

With three monitors, I know exactly where my windows are. If I have more than three windows that’s annoying, but I keep the extra ones on the middle monitor to simplify things.
And yet, if you think about parsing it, they're all ways to group things together. Avoiding adding reserved characters (see also the discussion about adding ternaries) is a worthy goal to pursue. Keeps the parser(s) simpler too.

An IDE / coloring scheme can help make things look more distinct if need be.

So is mine, and none of it is due to LinkedIn.

My most recent job search consisted entirely of friendly intros (most by colleagues at the hiring manager level) at a mix of startups and major tech companies. I have met these people through the normal course of business and life, and never through LinkedIn.

Maybe I'm special, because I've spent my career in tech consulting, so I got to network that way, but this is hardly a unique career path.
I wonder how this will go down with Palantir and Faculty - I can't imagine this was in their game plan.

I'm in the UK and I've almost given up on watching the news as it seems every step taken by the government is weeks behind where it should be, and taken in a reactive way, rather than there being any kind of proactive, coordinated response to the crisis. This is welcome, but months behind when it should have happened - plenty of discussion on here said the route they were trying to take wouldn't work for technical reasons, aside from one's of privacy.

By the time this is up and running, it'll be irrelevant.
That is true and besides the point which is that they are not responsible.
> I believe when you do that, the client/customer will coming to expect a quick response leading a "conversation" instead of an asynchronous email.

For me, this doesn't happen as much as I thought it would. I consistently get told how my support emails are a breath of fresh air compared to other software companies. Support emails can be an effective marketing tool. Done correctly, fast replies can definitely increase conversions or help with word-of-mouth marketing. As a one person business, doing things that don't scale is the advantage you have over other larger companies.

I don't respond to all emails immediately, especially low effort ones (or ones with dozens of questions that can be answered by using a free trial). However, I do believe there's a skill in learning how to read emails "between the lines" and determining if there's value in replying quickly.
Are you sure that applies generally, and not just to you and people like you?

"Legacy" web frameworks like Django, Ruby on Rails or Laravel.

While they won't give you an "advanced" front-end out of the box, the majority of functionality you'd need for an SaaS can be perfectly served by standard HTML and forms, for which those frameworks have excellent support (built-in form validation support, sessions, etc).

I am not aware of any complete full-stack framework that combines the functionality of these backend frameworks with a front-end component. Meteor could be an option but I haven't heard of any big project using it and there's probably a valid reason why.
