The nice point of Kiwi is that it supports Chrome extensions, this is why I am trying it. Browser extensions are something which I believe should be rather more widespread in Android by now.

FIREFOX has a regular setting to disable it. Better mobile browser in many ways!

I was filling and completing a report on a website, uploaded an attachment just wanted to fill up some remaining inputs on final step, while scrolling down the whole page refreshed!.. hours of work and composition was gone instantly, extremely frustrating!

An identifier embodies the information required to distinguish what is being identified from all other things within its scope of identification. Our use of the terms "identify" and "identifying" refer to this purpose of distinguishing one resource from all other resources, regardless of how that purpose is accomplished (e.g., by name, address, or context).

usage is also, however, a concern for the prescriptive tradition, for which "correctness" is a matter of arbitrating style
-
In the descriptive tradition of language analysis, by way of contrast, "correct" tends to mean functionally adequate for the purposes of the speaker or writer using it, and adequately idiomatic to be accepted by the listener or reader
-
-
www.thoughtco.com www.thoughtco.com
-
Usage seems to us peculiarly a matter of ear. Everyone has his own set of rules, his own list of horribles.
-
"Usage is trendy, arbitrary, and above all, constantly changing, like all other fashions--in clothing, music, or automobiles. Grammar is the rationale of a language; usage is the etiquette."
-
But when they ask, 'Does spelling count?' we tell them that in writing, as in life, everything counts. For academic writers, as for writers in a wide variety of fields (business, journalism, education, etc.), correctness in both content and expression is vital.
-
although we do point out the mistakes.
-
What interests us far more is that these apprentice writers have interesting ideas to convey, and manage to support their arguments well.
only partial match: the most important thing is the information (more than presentation/formatting)
-
New words, and new senses and uses of words, are not sanctioned or rejected by the authority of any single body: they arise through regular use and, once established, are recorded in dictionaries and grammars.
-
In this book, grammar refers to the manner in which the language functions, the ways that the blocks of speech and writing are put together. Usage refers to using specific words in a manner that will be thought of as either acceptable or unacceptable. The question of whether or not to split an infinitive is a consideration of grammar; the question of whether one should use literally in a nonliteral sense is one of usage."
-
Rules of proper usage are tacit conventions. Conventions are unstated agreements within a community to abide by a single way of doing things--not because there is any inherent advantage to the choice, but because there is an advantage to everyone making the same choice. Standardized weights and measures, electrical voltages and cables, computer file formats, the Gregorian calendar, and paper currency are familiar examples.

Not much to say except I'm really annoyed by the critics sometimes. This movie is solid. Has a vintage old-time feel to it. Well acted. Deals with the problems of the times (racism, bullying, war, alcoholism, death) in a dramatic, humorous and clever way.Great story. Whole family loved it. They dealt with faith in a reasonable way. They pulled heartstrings without being saccharine. The critics are just so dead-set on hating any movie that deals with faith, especially the Christian faith.

When a language presumes to know more than its user, that's when there's trouble.
-
Just because a language has a feature that might be dangerous doesn't mean it's inherently a bad thing. When a language presumes to know more than its user, that's when there's trouble.
-
I'd argue that when you find a programming language devoid of danger, you've found one that's not very useful.
-
The reason eval is there is because when you need it, when you really need it, there are no substitutes. There's only so much you can do with creative method dispatching, after all, and at some point you need to execute arbitrary code.
-
-
When is eval justified? In pragmatic terms, when you say it is. If it's your program and you're the programmer, you set the parameters.

transitive verb
It's hard for me to see the difference between the transitive and intransitive forms of this verb.
Is that the transitive form can/must be used with a noun following it, like "presume something", while the intransitive form cannot be followed by a noun, but can (and often is) followed by a prepositional phrase, "presume that something"? Pretty subtle difference, but I guess it's there...

The main usage difference is that dependency can be used in a second sense as a "concrete" noun to mean a person or thing which depends on something/someone else. But note that in the programming context it's not uncommon to see it used to mean a software resource upon which some piece of software depends (i.e. - reversing the need/provide relationship).
Is that really true? Can dependency refer to a person or thing which depends on something/someone else?? I'm only used to it the other way.
-
as a native speaker I'd probably tend to refer to his drug dependency, but his dependence on drugs (maybe because I see one as a problem he has, and the other as something he's doing, I don't know).
-
And as others have pointed out, there is potential for ambiguity: if A is dependent on B, then a dependence or dependency (relationship) exists; but referring to either A or B as the dependency demands context.
"demands context" :)
-
I think that "dependency" is usually the thing that you depend on, whereas dependence is the state of depending on it. But there are certainly cases where you could use either interchangeably.
-
If you want the easy way out (which looks like the way majority usage is going anyway), you can probably get away with using dependency all the time.
-
Dependence and dependency can both be used in the state/condition of being dependent sense.
.
-
-
There are certainly cases where you can use dependency and cannot use dependence: for example "The UK's overseas dependencies", or "This software releases has dependencies on Unix and Java". So if the dependent things are discrete and countable, it should definitely be "dependency".

I think "dependence" and "dependency" are like "competence" and "competency". Both are nouns. Yet, "dependence" emphasizes the quality of being dependent. So, it may also be abstract. Whereas, "dependency" focuses on the state of being dependent. It is likely to be concrete.
This seemed reasonable at first, but I'm not convinced it's the best explanation.
The conclusion at https://oneminuteenglish.org/en/dependence-or-dependency/ was a bit clearer, although mostly the same:
Just remember that “dependence” is the quality and “dependency” is the state of having to rely on someone or something else.
https://ell.stackexchange.com/questions/41528/differences-between-dependence-and-dependency/41561#41561 disagrees with the claim that "state" makes it likely to be concrete. And I like how it clarifies state as "state/condition" (condition is a lot clearer to me):
Dependence and dependency can both be used in the state/condition of being dependent sense. By definition, all words referencing such "states" are abstract nouns, so I don't see any justification for OP's abstract/concrete distinction in that sense.

I don't understand the distinction between quality and state.
Now that I mention it, neither do I. What's the difference between a quality and a state?

they're not wrong, but they don't teach what you don't know you don't know, whereas the one I link to makes this critical unknown unknown become a known unknown and then a known known. I didn't know you had a 1) local branch, 2) locally-stored remote-tracking branch, and 3) remote branch until I read that answer. Prior to that I thought there was only a local branch and remote branch. The locally-stored remote-tracking branch was an unknown unknown. Making it go from that to a known known is what makes that answer the best.

Kamatera is a very good option to run a mail server because They don’t block port 25, so you can send unlimited emails (transactional email and newsletters) without spending money on SMTP relay service. Kamatera doesn’t have any SMTP limits. You can send a million emails per day. The IP address isn’t on any email blacklist. (At least this is true in my case. I chose the Dallas data center.) You definitely don’t want to be listed on the dreaded Microsoft Outlook IP blacklist or the spamrats blacklist. Some blacklists block an entire IP range and you have no way to delist your IP address from this kind of blacklist. You can edit PTR record to improve email deliverability. They allow you to send newsletters to your email subscribers with no hourly limits or daily limits, whatsoever. You can order multiple IP addresses for a single server. This is very useful for folks who need to send a large volume of emails. You can spread email traffic on multiple IP addresses to achieve better email deliverability.

If you are watching this show with non-Chinese subtitles you are massively missing out. The Chinese dialogue is written with the skill of a bard. The language is sophisticated, succinct, elegant and poetic - as beautiful as the visuals. In comparison, the English subtitles were dull and prosaic, an abominable shadow of the original dialogue, using the vocabulary of a primary school student. It's as if the varying shades of blue - cerulean, sapphire, teal, indigo were translated into "blue, blue, blue, blue". I was truly disappointed by the English subtitles

If IFS is unset, or its value is exactly <space><tab><newline>, the default, then any sequence of IFS characters serves to delimit words. If IFS has a value other than the default, then sequences of the whitespace characters space and tab are ignored at the beginning and end of the word, as long as the whitespace character is in the value of IFS (an IFS whitespace character). Any character in IFS that is not IFS whitespace, along with any adjacent IFS whitespace characters, delimits a field. A sequence of IFS whitespace characters is also treated as a delimiter. If the value of IFS is null, no word splitting occurs.

In the author’s view, using a combination of content-addressing, signed content, and petnames would help decentralise that layer. It keeps centralisation around aggregators (because of the scarcity of attention), but mitigates their harmful lock-in.

You do not need to buy the expensive Cascade Plus surfactant. You can use any clear shampoo you can find at Dollar Tree. The application rate is 3 ounces per 1,000 square feet. If you have 2,000 square feet to spray, put 6 ounces of shampoo into a hose-end sprayer, fill the jug carefully with water, and spray it out as evenly as you can over the entire yard. If you use too much, no problem. A friend of mine sprayed at 64 ounces per 1,000 and never had a problem. So spray your yard and follow that up with 1/2 to 1 inch of rain or irrigation. Wait 3 full weeks for the magic to happen. Once it does you will find that after a rain or deep irrigation the soil will become unsettlingly soft and it will return to very firm/hard underfoot when the soil dries out.
This is not my rant alone. I’m simply conveying what is well known in some of the better lawn care forums online. I did not believe in the shampoo treatment until I tried it. Before that all I knew was that core aeration did nothing for my lawn. So I spent a dollar on some cheap shampoo, and it worked way beyond my expectations. Also one treatment seems to last for many years as long as you don’t neglect watering for many weeks during a very hot/dry summer.

Since the Console UI is a web-based app running on the customer’s browser, there are a few challenges we had to overcome due to the limitation set by the browser environment. Typically, the SSH protocol runs over a TCP connection. However, a raw TCP connection isn’t allowed by most browsers. Moreover, even if we had a way to support a direct TCP connection from within the browser, the Console UI still would not be able to connect to the target Droplet due to CORS limitation unless we assigned every Droplet a sub domain that complies with the CORS requirements, which is impractical.
-
When building the Droplet Console, we had a few options to support SSH keys-based authentication. The most straightforward way would be to directly allow the customer to specify a private key that is already set up for accessing the Droplet. However, there are some problems with this solution:

files with characters after the last newline are not text files, and those characters don't constitute a line. In many cases those bogus characters are better left ignored or removed, though there are cases where you may want to treat it as a extra line, so it's good you show how.

There is actually no meaningful distinction between a hostname which happens to be a second-level domain and a hostname which has more parts than that. You can even have a machine at a top-level domain if you happen to be a small country or otherwise are able to create an A record for one.

The host itself does not handle the actual FQDN. That is handled by the DNS. FQDN (Fully Qualified Domain Name) is handled by DNS translating names into IP addresses. Using the /etc/hosts file, you are essentially overriding the DNS server.

To ensure your messages pass the DMARC check with flying colors, you'll need to make certain the domains listed in the From, Sender, and Mail-From headers match each other exactly. That is, the domain listed in the From header is the exact actual sending domain.
-
For example, if your sending domain is ABCdomain.com, but your From field shows 123domain.com instead, you will almost certainly run into DMARC issues. Sometimes, even the difference between mail.ABCdomain.com and ABCdomain.com is sufficient for a server to place your message in a spam folder. We make sure that our Email Best Practices are clear that the domain listed in the From header and the actual sending domain should match for exactly this reason.

Note that the mere presence of this header causes premailer to be skipped, i.e., even setting skip_premailer: false will cause premailer to be skipped. The reason for that is that the skip_premailer is a simple header and the value is transformed into a string, causing 'false' to become truthy.
They should fix this!

sums = [0] (1..gains.length).each do |i| sums[i] = sums[i - 1] + gains[i - 1] end could, if scan was introduced, be replaced with: sums = gains.scan_left(0, &:+)

I'd even go as far as saying each_with_object is often less readable than using a captured variable.
elaborate? what is a captured variable? I assume he means the val = 0 from outside the scope of the block, which was "captured" in the closure.

I think "purely functional, not a single re-assigned variable" often introduces significant extra complexity, when Ruby is a language that embraces both functional and imperative programming.
-
One of my favorite aspects of Ruby is how easy it is to write in a functional programming style, and including the scan operation would expand the number of use cases covered by functional methods.
-
each_with_object is only useful if mutating some object (typically an Array or Hash).
typically true... is it always true?
-
I think this is the crux of the issue. Because #inject needs to evaluate every element in order to return a meaningful value, it can't be partially evaluated. The "scan" operation allows for partial evaluation.

I think there are real-world use cases! Would you consider converting a history of transactions into a history of account balances a valid use-case? That can be done easily with a scan. For example, if you have transactions = [100, -200, 200] then you can find the history of account balances with transactions.scan_left(0, &:+) # => [0, 100, -100, 100].

no mention of each_with_object having a lazy implementation which is most likely why your second example loops forever.

The key differences between #inject and #scan_left are: Incremental results: #scan_left returns a series of results after processing each element of the input series. #inject returns a single value, which equals the final result in the series returned by #scan_left. Laziness: #scan_left can preserve the laziness of the input series. As each incremental result is read from the output series, the actual calculation is lazily performed against the input. #inject cannot be a lazy operation in general, as its single result reflects a calculation across every element of the input series.
