You're quoting the introduction of the article, which is notoriously a fuzzy abstract in all the wikipedia articles about mathematical concepts. Let's quote the actual (textual) formal definition (sec. 1.1) as it would stand in a textbook:

> Formally, a field is a set F together with two binary operations on F called addition and multiplication. A binary operation on F is a mapping F × F → F, that is, a correspondence that associates with each ordered pair of elements of F a uniquely determined element of F. The result of the addition of a and b is called the sum of a and b, and is denoted a + b. Similarly, the result of the multiplication of a and b is called the product of a and b, and is denoted ab or a ⋅ b. These operations are required to satisfy the following properties, referred to as field axioms. In these axioms, a, b, and c are arbitrary elements of the field F. [...]

Still, i don't know how to say it in another way but you probably don't have much experience in mathematics, even the first quote is arguably quite accurate.

> Does it mean that any 2 elements combined together using that operation always need to output an element which is also in the same set?

Yes, unless told otherwise an operation is an internal binary operation, it's really the most common form. When it is not the output is notable enough to be specified.

> But if that was the case then "behave as the corresponding operations on rational and real numbers do" would mean that the fields would always need to be of infinite size wouldn't it? Because if the field had a limited number of elements and you added the last two (highest) elements together [...]

No, the important point here is your use of "highest". A set by default only has equality (and mappings, in and out) but no order relationship. So the most conservative interpretation of "behave as the corresponding operations on rational" would be to only include stuff that can be written using the 4 operations and equality, not ordering.

---

Maybe i'm biaised by the fact that i know what a field is, but still, this particular intro is also how i would present a field: give the most common example and say which operations it has. It sure can create false intuitions like yours about the size, but this will always be the case when we use non-normalized language.
The fact that sometimes suffering is very intense and temporary and that forcing someone to live through that can later lead to a fulfilling and happy life. A life where they are grateful they suffered through the temporary thing without ending it.

That alone should be enough to acknowledge that sometimes, people who want to die should not kill themselves.

Besides that, the fact that quite often, a person killing themselves will inflict a lot of suffering on their surroundings. If you argue we don't get to force someone to suffer, why does a suicidal person get to force others to suffer?

Neither the position "No one should ever get to end their own life" nor the position "Everyone should be able to end their own life at any instant of their choosing always and immediately" seem tenable to me. With a decent solution lying somewhere in between these to positions.
Make a list while not with a therapist -- what do you want to fix?

Another way to start is checking if you match these (though you could be suffering from one and not even recognise it by reading the abstract description): https://en.wikipedia.org/wiki/List_of_maladaptive_schemas -- if you match any, this is a great place to start, regardless of the therapy affiliation.

I really like Schema Therapy, though I've only seen one therapist qualified in it, and while she started great -- gave me a long questionnaire that pointed out my maladaptive schemas I already knew were present(she made me feel "wow, finally, a great professional, just like I read in the manual they should be"), she just didn't stick at all to the Schema Therapy session protocol I read in the manual and the sessions just devolved into the usual "so how have you been since our last session .... bla bla bla ... you're making great progress" that I'm all too familiar with all the therapists that I know.

So whatever therapy you choose, try to find a therapist that's also sticking to the therapy method.
Big mistake in the article: the discrete log is not a trapdoor function, as far as we know, and elliptic curve crypto does not rely on trapdoors.

A trapdoor function is when you have a function hard to invert (for any x, given y = f(x), find x), which inversion becomes very easy once you know some additional info.
For instance in RSA, given c = m^e mod N, it is hard to find m. Unless you know d such that e*d = 1 mod phi(N), then you can easily find m by computing m = c^d mod N.

There is no known way of easily inverting exponentiation on finite groups.

To quote Wikipedia, "Functions related to the hardness of the discrete logarithm problem [...] are not known to be trapdoor functions, because there is no known "trapdoor" information about the group that enables the efficient computation of discrete logarithms. "

In my experience, they will be happy to start anywhere, like just how is your day today for example. You can just talk and they will listen and ask about stuff that they think might be relevant. Whatever is “wrong” it will probably come up in some way if you just talk about your day with an experienced therapist. You don’t need a clear statement to come with, they know that they’ll have to talk and that it might even take several sessions to start formulating something.

I can imagine even starting by saying “I don’t really know what is wrong and what to say, so I’m afraid I’ll just be awkward and you’ll think I’m an idiot” and they’ll be like “Haha, that’s interesting, do you often feel like other people might think you’re an idiot?” and you’re up and running!

It all depends on what somebody is looking for: a sortable data table for presentation, a table (structure) editor, a spreadsheet, a data grid? All these things look very similar, but they require different approaches really.

You'll always lose on one of the other. Ag-Grid and DataTables are perfect for presentation, not so much for Excel-like editing. Handsontable & Jexcel try to implement all features of Excel, at the cost of performance & bugs.

I have to make sure that in my marketing I make very clear that my product won't be able to do X,Y and Z, but it's the best at A,B and C. To prevent disappointed buyers.

I hope I am doing that with my Features & Limits page: https://www.datagridxl.com/docs/features-limits. (Column sorting will be implemented soon by the way. Ignore what the page says.)

I am thinking to add some interactive comparison pages like: DataGridXL vs Handsontable, DataGridXL vs Ag-Grid, DataGridXL vs DataTables, etc... to really show & describe the differences between the products.

Anyway, you're always welcome to use the free version. It only requires that you keep the branding link visible, which might not be too bad for your app
I would agree with you, you can't pay someone to replace what your parents didn't do with a session once a week.

Did you ever consider looking for another therapist?

> You can't avoid null and undefined

We are speaking about just null, not "null and undefined". Believe it or not, I simply do not use null in JS. Study the concept of "truthy and falsy" in JS.

> Accessing a missing property or method results with undefined. Hope you remember the exact method names and field names of all objects in your codebase!

I don't. I do however structure my code predictably, using consistent naming conventions and patterns. I hope you do realize JS existed for over 20 years before TS, and complex apps like gmaps and google docx were built entirely in JS.

> Using "str".match(regex) results with null if there are no matches.

const match = /bar/.exec("str");

if( match ){

// am only interested in what happens if foo returns a *truthy* result.

// The exact type of a falsy result is irrelevant, it either matches (truthy) or it doesn't (falsey)

}

I seem to lack the ability to see what you find obvious. Perhaps we differ in what counts as supporting evidence or maybe our starting assumptions are drastically different.
Fanta, Autobahn & Volkswagen are also products of the Nazis.

One of the reasons Modi/BJP's opponents failed is because of the level of ridiculous accusations they level against them.

An one point even staunch communists and Congress supports lost faith in their politics.

I really do not understand how much people can hate the success of others. Contrast Reliance with the likes of Karunanidhi dynasty or the Gandhi dynasty, not only do these dynasts directly loot public money in the billions. They also have them stashed abroad, often in sensitive projects like Hamabanthota run by enemy states like China.

> If the best deal isn't on Facebook people will go elsewhere.

But do they? Or do they just find the best deal on facebook, and then select that deal? In which case, you end up with defacto regulation by facebook because if they choose to remove your deal, you are effectively being regulated by hidden rules you have no control over.
I think the main problem with phones is software support. I have a Samsung S7 (released March 2016), which is perfectly fine hardware wise. But I'm going to need to upgrade it soon, because it's no longer getting security updates.
With most of these (cell free DNA) assays, its not a single site that you are measuring but a statistical aggregate about profiles that have been defined for a certain cell type. If you know the overall profile of prostate cells and the profile of normal blood, you can subtract the expected profile from a patient sample and the analyse the left-over fraction for whether it is just noise or is matching to one or multiple known cell types.

The surprise from this publication is only that they detect such signatures 4 years earlier than other non-invasive testing. (although nobody in the cfDNA field would be surprised about that).
It's really sad. Not just medium but Facebook, twitter, YouTube all blocked such content/posts and tried to stifle the content creators. YouTube even permanently banned many channels. I didn't know medium did the same.
i dont see how fb is a gatekeeper here. they have a product that is better than all the other freemarket alternatives for these people... no gatekeeping, no regulations forcing people to use fb
I like his point about lack of ambiguity. Nothing makes me want to punch an author in the head (without, to be clear, any possibility I would actually do it) like lazily creating an ambiguous notation, which is supposed to be "clear from context", but rarely is. As for example the Einstein summation convention which is to be ignored "when clear from context".

I would add

1. Clearly telegraphing notations. Not hiding them in the middle of long paragraphs or even, and yes I have seen this a few times, defining essential notation in an optional exercise.

2. Having a glossary of notations, so people don't have to remember every single notation and to read every word of the book sequentially.

3. Not creating low value notations that may be used only once and then, possibly forgotten. I have read books with > 1 new notation or definition per page, mostly forgotten thereafter but some random subset needed later, and you are not to know which.

That "blocklist/passlist" alternative is horrible - blocklist has always been a list of blocks (and that's how it is used in kernel now).

Css native's scroll-snap was not useful in my case, but in the end DGXL's custom scroll snap was one of the easiest parts of the product to build. It was one of the things I really wanted to get right.

Using a <table> tag would always be best for accessibility reasons, but it's not an option if you want to create a performant data table with thousands of rows. I am still using HTML, not Canvas, so it is accessible, but it needs improvements.

A great relief is that this is an input-component first of all, to be used in admin-areas. So there's no need for SEO-compatible HTML.
I don't see your point. Code that's more modular, pluggable is by definition easier to delete. That should not be a reason to prevent us writing easy to delete code.

Covid-19 Vaccines with ‘Minor Side Effects’ Could Still Be Pretty Bad
Journalists typically ask two questions here: 'does this person wish to be named?' and 'is it in the public interest to ignore this request?'. It is highly dubious that there is any public interest in revealing Scott's name, hence the outrage.

Second, depending on the story and person, revealing a name can very easily lead to revealing phone numbers and addresses. So this isn't just 'a name'.

Finally, Scott very clearly does not want to be a public figure.
Doxxing is a classical example of the ad hominem logical fallacy. Criticise the argument, not the person making it.

Sniffing is a process of monitoring and capturing all data packets passing through given network. Sniffers are used by network/system administrator to monitor and troubleshoot network traffic. Attackers use sniffers to capture data packets containing sensitive information such as password, account information etc. Sniffers can be hardware or software installed in the system. By placing a packet sniffer on a network in promiscuous mode, a malicious intruder can capture and analyze all of the network traffic.
There are two types:
Active Sniffing:
Passive Sniffing:

Better or worse, little of what the executive does is really because of the president directly. The president chooses the sort of people to put in positions of power then the whole ship largely sorts itself out. But the president gets to be responsible for everything because they are nominally in charge, and people keep pretending they are superheros with all sorts of ability to personally oversee how the US operates.

We can certainly say that if Trump didn't want quantum computing research to happen his administration wouldn't be doing it. So if it does, he has de facto supported it. Even if by inaction.

I've been diagnosed with BPD.

I've seen three personal therapists and a couples therapist.
They all helped and I learned some tricks from them, clarified things, my BPD symptoms have diminished, but they tend to do so with age without any therapy.

All therapists sucked in the same regard -- they fail to follow through -- I've heard so many times "oh, for this issue I know this great exercise and this great technique, we'll practice, bla bla bla", only to forget about it by the next session.

Resources are quite widespread, if you want a community based learning, IBM's Qiskit[0] is the best. If you are at high-school level, Michael Nielsen's online mnemonic book [1] is good too. Ideally, you want to get a small grasp of basic probability, some physics and algebra. Another community based learning is QWorld [3].

Journalists and writers in general aim to make a story appealing to their readers. One way they do this is bring to life their subjects, and some ways they can do that is to name the subject, tell readers what neighborhood the subject lives in, age, what kind of life they lead etc. People are interested in other people.

It has value but it's a mechanism that isn't necessarily needed in all cases.

One could do a thought experiment imagining a group of newspaper readers evaluating an edition where names of subjects were not given and one where they were. Which edition would be more interesting?
A yes, the good old "other people have been treated worse in the past so it's ok to treat that person badly now" argument.
Well, I don't know much about this person or the article that was coming up, hence making a general point. [0]

But generally when writing a piece on anybody it's normal to gather all kinds of details about one's life. Profession/job, educational history, some basic family background and name is usually one of them too.

Now again if the journalist has a good relationship with the person and they say they really want to go by XYZ instead of their full name, this is a perfectly valid request to me. But the notion that one is committing a grave crime if they don't comply (or ask) is another story.

Say back in the day I wrote a little piece on something that had absolutely nothing to do with me. Some journalist got interested in it and called me to discuss it. Spent most of the time discussing my own background. Hardly talked about my story at all. Wasn't enthused about this but I understand that's something people generally want to know.

[0] I mean correct me if I'm wrong but this person publishe[s/ed] under their regular first and second name. Mentions his actual life and experiences in his publicly available writings. Is generally easy to track down. Has a big cult following. But wants their last name redacted. Again, not saying that the journalist shouldn't honor the request. But nonetheless the whole situation is a bit bizarre. And sooner or later his full name will be out there (probably already is). So he's essentially asking for his full name not to rank too well in search results?

had an experience this spring with picking up Thai food from a Chinese restaurant which is also home to:

- Chinese Yum! Yum!
- Szechwings
- Kuri Sashimi Bowls
- Send Noods Pho
- Veggie Stir Fry House
- Sushi Sendai
- Panang Panang! Thai Curry
- Save the Fish Vegetarian Sushi
- Fire Ass Thai

and so on. at least 25 restaurants by my count.

I don't know if I believe that this is a problem (beyond the usual kinds of problems in restaurants) and I'm mostly curious about how the logistics are managed. is there a wall of iPads so each "restaurant" front gets all its own orders on one? does whatever company that facilitates this kind of thing provide a solution where manifold orders can come in on a more traditional kitchen display system with some flag added for which "restaurant" it belongs to?

making the various menus work doesn't seem like as big of a challenge: the majority of the client restaurants are offering whole subsets of the host restaurant's menu or food easily reconstructed from those items.
Haha yep, hit a Go logging library where the documentation was a link to a Medium post. That raised my eyebrows.
I accept that many people have incurable illnesses which are either literally torturing them or slowly robbing them of everything they value.

The reason I am (slightly) against euthanasia despite this, is because I expect easy availability — to be clear, a culture where it is not even controversial rather than merely available lawfully — to also be world where it is easy for people who don’t fit that category being pressured into talking that path.

The reason I’m only slightly against is that I don’t feel confident in weighing the quantifiable decrease in suffering with the probability distribution of possible increases in needless death.

That, plus I recognise my argument is “that looks like a slippery slope”, where the real problem may well be that human behaviour isn’t what my imagination is telling me it is.

Wikipedia tells me the per-capita GDP of Bangladesh is ~$2,173.

Yes, they do. They aren't sitting around thinking "welp, I've got so much money I'll just give up on shopping around". That attitude is a luxury for people with 5 figure incomes.

Maybe wealthy Bangladeshians don't bother. My heart bleeds for them and the bad deal they just accepted.

Yup. As greek to me as the paper is at least it makes very clear what it sets out to achieve and why (and when) it differs. I suppose it's implicit but I feel article really ought to explain that in the demonstrated case of heavy bias, few attempts and fixed, coarse steps there is of course no advantage - apart from the stick in ground one could also best its resolution off 0b1000000 and ++/--.

It's a nice explainer on polarization but tries to be more than that and doesn't achieve it - but with further work (not in form of added caveats but rather a new approach to tying the two concepts together) I'm sure it could.
I had my rant about BSNL down below. BSNL by a far distance has to be the worst in terms of Customer service , which is sad because i know of brilliant engineers who joined as Junior Engineers in BSNL clearing PSC. Unless there is accountability , there is no chance BSNL will survive.
