    1. Part of the reason is there’s a slight lag. No matter how good your internet is, no matter how fast it is, it seems we have this millisecond—maybe a few milliseconds—delay. So the communication isn’t in real time, even though it seems like it is. Our brains subconsciously pick up on the fact that things aren’t quite right. And the fact that things are out of sync and we’re accustomed to them being in sync when it’s face-to-face communication, our brains try to look for ways to overcome that lack of synchrony. After a few calls a day, it starts to become exhausting.

      Does this mean, if I'm naturally slow to react even in real life, it'll be exhausting for the interlocutor?

    1. we calculated for every participanta similarity indexSdescribing the correlation of responses

      S = 2P - 1 where P is the proportion of answers the same between both conditions

         -1 (opposite)    0 (no similarity)    + (same)
      

      If P is high:

      • S = 2(.9) - 1
      • S = 0.8

      If P is low:

      • S = 2(.2) - 1
      • S = -0.6

    1. Question design is one of the key tools we have at our disposal when trying to get people to work together. The art of turning a “should” statement into a “how might we” statement works something like this: for any “should” question, understand what the goal of the proposed solution is, and then frame a “how” question around that goal.

    1. Yet, this is another reason why Sanskrit seems more suitable than other languages. The strict grammar rules, syllables, and words have reduced ambiguity making the literal meaning word and sentence. This definitely reduces the percentage of abstract meanings in the language.

    1. Then when giving answers I'm even less certain. For example I see occasional how-to questions which (IMO) are ridiculously complex in bash, awk, sed, etc. but trivial in python, (<10 lines, no non-standard libraries). On such questions I wait and see if other answers are forthcoming. But if they get no answers, I'm not sure if I should give my 10 lines of python or not.
    2. There is an observable widespread tendency to give an awk answer to almost everything, but that should not be inferred as a rule to be followed, and if there's (say) a Python answer that involves less programming then surely that is quite on point as an answer for a readership of users.

    1. This isn’t an accident. OpenOffice’s sidebar code was copied and incorporated into LibreOffice. The Apache OpenOffice project uses the Apache License, while the LibreOffice uses a dual LGPLv3 / MPL license. The practical result is LibreOffice can take OpenOffice’s code and incorporate it into LibreOffice — the licenses are compatible. On the other hand, LibreOffice has some features — like font embedding — that don’t appear in OpenOffice. This is because the two different licenses only allow a one-way transfer of code. LibreOffice can incorporate OpenOffice’s code, but OpenOffice can’t incorporate LibreOffice’s code. This is the result of the different licenses the projects chose.

      What part of LGPLv3 / MPL prevents LibreOffice code from being incorporated back into OpenOffice's Apache Licensed code??

      it seems that these are more taglines than slogans.

    1. In the Set class we already called this - and difference, which it is ok but not really accurate because of the previous explanation, but probably not worthwhile to change it.

      Is this saying that the name difference is inaccurate?

      Why is it inaccurate? You even called it the "theoretic difference" above.

      Is that because "relative complement" would be better? Or because the full phrase "theoretic difference" [https://en.wiktionary.org/wiki/set-theoretic_difference] is required in order for it to be accurate rather than just "difference"?

    1. With this second scheme, the DBMS stores the physical addressof versions in the index entries. This approach is only applicablefor append-only storage, since the DBMS stores the versions in thesame table and therefore all of the indexes can point to them. Whenupdating any tuple in a table, the DBMS inserts the newly createdversion into all the secondary indexes. In this manner, the DBMScan search for a tuple from a secondary index without comparingthe secondary key with all of the indexed versions. Several MVCCDBMSs, including MemSQL and Hekaton, employ this scheme

      Physical Pointers: 只对Append-only storage有用

      问题:“since the DBMS stores the versions in the same table and therefore all of the indexes can point to the”这句话怎么理解

      Likewise, using physical pointers is better for read-intensive workloads because an index entry points to the exact version. But it is slower for update operations because this scheme requires theDBMS to insert an entry into every secondary index for each new version, which makes update operations slower

    1. tunnel splitting

      What exactly is tunnel splitting? The essay mentions this various times without clearly explaining what it is, and whenever I search it up online multiple things are said about it.

      From what I could understand, quantum spin tunnel splitting makes it so that the magnetization of a system can "switch between states with opposite magnetization that are separated by an energy barrier much larger than thermal energy". But what exactly happens during tunnel splitting? And why are there different ones mentioned in the article? [magnetization tunneling, zero-field tunnel splitting, ground-state tunnel splitting]

      I also understand that this phenomenon "defies classical physics" because of magnetization switching. How is that possible?

      Strictly speaking, are these examples of dualities (https://en.wikipedia.org/wiki/Duality_(mathematics))? Or can I only, at strongest, say they are analogous (a looser coonection)?

For this reason, you must make it clear that signing up is optional. This is especially relevant in cases where you offer free white-papers (or e-books) for download. While the user’s email address is required for the delivery of the service, signing up for your newsletter is not. In such a case, you must not make it appear as if signing-up to the newsletter list mandatory and must make it clear that it is optional.

      Question (answer below)

      Are they saying that it's not allowed to make signing up for a mailing list a precondition/requirement for anything? This was surprising to me.

      So if you have a newsletter sign-up page that sends a digital bonus gift (like an e-book) to new subscribers, are required to completely change/repurpose your "newsletter sign-up page" into a "download e-book page" (that has an optional checkbox to also sign up for the newsletter, if you want)? That seems dumb to me, since it requires completely reversing the purpose of the page — which was, in my mind, primarily about signing up for the newsletter, with a bonus (an essentially optional one) thrown in for those who do so. Are you required to either repurpose it like that or remove the free bonus offer that would be sent to new subscribers?

      The irony of this is that it requires websites that have a newsletter sign-up page like that to change it into a "newsletter sign-up page" where the newsletter sign-up part is optional. Which make you look kind of stupid, making a page that claims to be one thing but doesn't necessarily do what it says it's for.

      Does this mean, in effect, that you may not lawfully provide any sort of incentive or reward for signing up for something (like a mailing list)? As long as it's very clear that some action is required before delivery of some thing, I don't see why this sort of thing should not be permitted? Would this fall under contract law? And as such, wouldn't such a contract be allowed and valid? Are mailing lists a special class of [service] that has special requirements like this? Or is it part of a broader category to which this requirement applies more generally?

      Why is requiring the user to provide an email address before they can download a digital reward allowed but not requiring signing up to a mailing list? Why isn't it required that even the email address be optional to provide? (To answer my own question, probably because it's allowed to allow a user to request a specific thing to be sent via email, and an email address is required in order to fulfill that request. But...) It seems that the website could just provide a direct link to download it via HTTP/FTP/etc. as an option for users that chose not to provide an email address. (But should they be required to provide that option anytime they / just because they provide the option to have the same thing delivered via email?)

      Answer

      Looks like my question was answered below:

      Explicit Form (where the purpose of the sign-up mechanism is unequivocal). So for example, in a scenario where your site has a pop-up window that invites users to sign up to your newsletter using a clear phrase such as: “Subscribe to our newsletter for access to discount vouchers and product updates!“, the affirmative action that the user performs by typing in their email address would be considered valid consent.

      So the case I described, where it is made very clear that the incentive that is offered is conditional on subscribing, is listed as an exception to the general rule. That's good; it should be allowed.

    1. Ideally you should really test these parameters (by comparing to ab initio calculations for example) to ensure they are reasonable

      How to compare?

    2. C, N, O, S, P, H, F, Cl, Br and I

      GAFF only supports 10 elements?

    1. Regular Expression Functions There are three regular-expression functions that operate on strings: matches() tests if a regular expression matches a string. replace() uses regular expressions to replace portions of a string. tokenize() returns a sequence of strings formed by breaking a supplied input string at any separator that matches a given regular expression. Example:   

      Test question: how many are there regular-expression functions in XSLT?

    2. What’s the difference between xsl:value-of, xsl:copy-of, and xsl:sequence? xsl:value-of always creates a text node. xsl:copy-of always creates a copy. xsl:sequence returns the nodes selected, subject possibly to atomization. Sequences can be extended with xsl:sequence.
