Perhaps SE wants to keep that a secret.
maybe I'll start tracking it! lay the truth bare
but I suppose it wouldn't tell us about people leaving, only people who get deleted/destroyed
They could make a stat "users crossing the threshold of being inactive for six months".
> IS Khorasan is verzwakt door een serie nederlagen, waarbij het zijn territorium in de provincie Nangarhar kwijtraakte. Maar de groep heeft volgens The Soufan Center een ambitieuze nieuwe leider, Shahab al-Muhajir, en blijft aanslagen plegen. De vraag is echter hoeveel rekruten en speelruimte hij krijgt nu de Taliban de teugels van de Afghaanse staat en geavanceerd Amerikaans wapentuig in handen hebben gekregen.
They've got "[users who] acted on at least one day [in the week or month]"
"The Islamic State in Afghanistan has been greatly weakened, but it has a new, ambitious leader who might turn things around. However, now that the Taleban have captured huge amounts of advanced American weaponry, perhaps they will suppress the IS (IS and Taleban are enemies)."
Wouldn't that be funny.
Yes. An interesting coincidence
13:06
The Taleban capturing billions of dollars of advanced American weaponry from the former Afghan army will actually help the Americans suppress IS.
We shall see.
I read that Biden's approval rating has decreased sharply, even in his own country.
His first big mistake, perhaps.
Perhaps
Both he and Trump promised to withdraw troops. I wonder if people voted expecting that to be an empty promise, too
I think American voters wanted the withdrawal.
Back to the discussion about experts leaving ELU...
There never really were.
Touchés.
It's not like SE where everyday practitioners, engineers working every day in a knowledge field fixing there own work, seeking answers to their own work, realize they can also help others.
There are literally millions of wordsmiths out there, journalists, foreign language teachers, general academics, etc etc who would be able to answer every single one of the questions on ELU, no matter how asinine or entitled, with quality terseness and depth and understandability.
Yet they are not here.
13:20
Where?
Sure there's a handful, a very small handful, of professionals who must have a lot of additional time on their hands who answer every so often with intelligence and support. And there are a handful of amateurs who also answer similarly.
But for the most part it is junk.
How negative.
Is this about all of SE, or just ELU?
@Cerberus Just ELU. I don't really know SE except as a very informal SE programmer (ie programming by cut and pasting from SE) and it's 1) a lifesaver but 2) hit or miss quality wise.
Naturally.
I suspect you copied your code from SO?
We all know that Urban Dictionary is junk, but the news will refer to that well before ELU is even thought of, researched, and then dismissed because it purports to be by experts but isn't. Whereas UD is authentic, it doesn't have pretensions and so can be, well, not trusted, but more easily judged
@Cerberus little pieces
Re the 'Afghan vs Afghani' blow up yesterday. No one in the world thought to consider ELU as a primary source.
13:28
@Mitch philistines
But to your point @Cerberus, yes I see that charity would be the better move to improve quality than button pressing/rule of law following.
@MattE.Эллен Realists
But really, SE has been headlined, has almost become recognizable to the mainstream.
(by 'SE' I mean the first programming Q&A not the platform.. I can never remember which is which)
so...
which one is that?
13:31
StackOverflow
and...
which one is that?
@RegDwigнt I hate when your instrument decides to play tricks on you. Flute doesn't have much that can go wrong—other than operator error. My worst was miscounting one time and coming in a measure early in a quiet section. Right out there in front of God & Everybody.
The Q&A site for fixing code, but not Code Review
OH
and SE is the whole big platform?
13:33
so you're saying that all this time I've been shaking hands with my left hand?
goddamit
It's confusing because of the company name changes. It was Stack Overflow Inc. then Stack Exchange Inc. and now it's Stack Overflow Inc, but the platform for public Q&A is Stack Exchange
Anyway, I think the 'ass' question is interesting sociolinguistics, even if the questioners wording is a little 'ranty'.
I need to retrieve my oven pizza
@MattE.Эллен If I knew that I would be even more confused.
And I'm confused enough as it is
@MattE.Эллен No worries, I keep going and you can check the transcript later.
@Mitch Oh, authentic, is that it.
13:39
No need to edit the ass question much or at all, just bend it slightly to whether profanity (or 'ass' in particular) is considered acceptable in certain registers... mention the softening of other profanity in English in general acceptablility in the news, 'cunt' in Scottish English, then throw in some Russian mothers and woo hoo you're done.
@Mitch What blow-up?
Did I miss anything?
@Mitch Yay.
@Cerberus That's my analysis. You -know- it's not experts so you trust that they're kids just saying shit not very well.
@Mitch Agreed.
@Mitch Bend it slightly, OK.
Sound advice.
Does that constitute a blow-up?
13:43
@Mitch Does this mean the inhabitants of Spaghettistan are called Spaghetti?
@Cerberus For me, yes.
In my days, nobody would have noticed. Now, WWII, that was a blow-up.
(Jake Tapper is a primary news guy on CNN)
(and twitter is not unimportant)
No comment.
@Cerberus Oh. Yeah. I guess.
13:44
Someone posted something on Twitter, noted.
@Cerberus You have revealed yourself by your pointed disengagement.
@Cerberus haha. but...
Unless you mean the picture is blown up in chat.
@Mitch Oh, not again...
@Cerberus no it's about the same size
Oh, OK.
maybe I spoke too soon.
about the blowup
13:46
How is that possible?
Speaking too soon, on Twitter?
twitter is a bigger deal than ELU so there's that
and by bigger deal I mean
I hope it shall die soon.
At least it has never become large like Facebook.
I haven't checked.
Russo's is/was an awesome store. Great produce, cheeses, you name it.
@Robusto The guy is tired.
13:50
When I worked in Waltham we used to go down there to get sandwiches all the time.
@Mitch Innocence is no excuse.
@Robusto No one goes there anymore, because it is too crowded.
Thank you, Yogi.
They just finished renovating their parking a few years ago.
Best place for last minute xmas trees.
My son lives in Watertown and he's very sad about this.
Russo's was not a factor in his moving there, but it was a "nice to have" extra.
> In Zuid-Afrika ontstond verontwaardiging toen bleek dat farmaceut Johnson & Johnson vanuit een fabriek in Zuid-Afrika meer vaccins exporteerde naar Europa dan hij in Zuid-Afrika zelf had verstrekt. Zuid-Afrika bestelde 31 miljoen vaccins, maar ontving vooralsnog slechts 2 miljoen doses voor de eigen bevolking.
Volgens onderzoek van The New York Times werden in de Aspen Pharmacare-fabriek, in de havenstad Port Elizabeth, de afgelopen maanden zeker 32 miljoen doses van het Johnson & Johnson-vaccin ingepakt voor export naar Europa. Het contract schrijft voor dat Zuid-Afrika niet het recht he
13:54
@Cerberus It's a strong presence but of a particular kind. Also things change over the years with twitter, but Facebook seems to be even stronger in what it always has been.
South Africa has exported 32 million doses of the Janssen vaccine to Europe, but received only 2 million itself.
As for the A–Z vaccine, South Africa pays 2.5 times as much per dose as does Europe...
@Cerberus Deficit spending?
I think it is just power politics and a poor negotiating position.
"The Janssen contract says SA cannot prevent the factory from exporting vaccines."
It's not the government that does this, but the Western multinationals.
And Europe is apparently accepting all those vaccines.
Even though few people even use the Janssen vaccine here.
@Cerberus Also, it is a private company who just happens to have multinational infrastructure. just because there's a factory in SA doesn't mean necessarily that it's producing for SA.
Pretty disgraceful.
@Mitch No, but it's still pretty horrible.
13:57
@Cerberus No disagreement that it -looks- bad
And Europe was being all whiny about how many vaccines it was exporting compared to how many it received itself.
I'm sure there will still be a huge net export surplus for Europe, but still.
At least India stopped exports at some point.
In some sense, all the manufacturing should be directed towards sending to India and China and Africa
and having a small percentage for NA/SA, Europe
Now that we have enough vaccines here, yeah, probably.
At least I think we now have about enough.
PSA for everybody: you should not forget to get your -flu- vaccine this fall (Sep or Oct).
And for the olds (I'm not sure what the age recommendation is) but consider also a shingles vaccine (for adult chicken pox/varicella).
14:15
@Mitch We do not get that here!
Only if you're over 60.
@Mitch I thought chicken-pox immunity was for life?
I get the 'flu vaccine because I have asthma
and old people get it because they can't run away either
healthy people don't generally get a 'flu shot here
Same here.
14:49
@Cerberus hm... I don't think so. I think maybe if you got it as a kid, it may reappear later in life as shingles.
@Cerberus I think here it is for all adults?
@MattE.Эллен hm... I used to work at a hospital and every fall they had a tent out for all employees (clinical or not) to get a flu shot.
15:02
@Mitch I thought that was a different disease, a kind of herpes.
@Mitch That's nice. But you probably have to pay for it?
> After a chickenpox infection, the virus remains dormant in the body's nerve tissues for about 50 years. This, however, does not mean that VZV cannot be contracted later in life.
The immune system usually keeps the virus at bay, however it can still manifest itself at any given age between 1 and 60, causing a different form of the viral infection called shingles (also known as herpes zoster).[32] Since the human immune system efficacy decreases with age, the United States Advisory Committee on Immunization Practices (ACIP) suggests that every adult over the age of 50 years get the herpes z
Odd.
So the same virus has different names?
@Mitch I think some workplaces here offer it, but on the whole it's not expected to get the shot unless you are "at risk"
i.e. it's not free if you're not at risk
@MattE.Эллен Yeah you could probably get it here if you pay. Though I'm not sure whether the government had bought enough vaccines to allow that.
How does these sound? Are they really incorrect?
1. The objective of the project is developing a framework.
2. Our objective of the project is developing a framework.
3. Our main objective of the project is developing a framework.
I would not use a possessive pronoun (our) together with a semi-possessive phrase (of...).
Well in that case what about "my objective is developing a framework"?
Maybe use a different preposition if you really must use our.
@Man_From_India Perfectly fine.
Your no. 1 also sounds fine to me.
15:25
If you don't mind my asking, you are native to US or UK
Or better question, native to AmE or BrE
No, but this is fairly standard usage.
Ask on ELL if you want more answers.
English Language Learners.
I searched COCA quickly and
My finding is that when "objective" is preceded by a genitive pronoun like "our/my objective" you can use "verb+ing", still rare. But "the objective" as it is is almost never used with "verb+ing", except in conversation, that too rarely. On the other hand there is no problem with vwrb + ing when "objective" is preceded by a modifier like "primarily/secondary objective". — Man_From_India 13 hours ago
But another probablyly BrE user thinks verb+ing is wrong. So a little confused. And that why I asked you if you are native to BrE or AmE
@Man_From_India I think Astral Bee is wrong.
He's probably overthinking it.
A gerund can be used without an article. He really wants to add the article (the developing of...), but it is not required.
It's just a slightly different construction.
Yes I don't agree with what grammatical point he made in his answer.
And his argument why just developing should be wrong is mistaken.
15:31
nods
He assumed developing must be a participle rather than a gerund.
But the real question is, can the gerund be used without an article here?
From COCA I furnished some example sentences over there in my comment. And it seems it can.
The examples you posted there are good.
It can happen to the best of people: you over-analyse a sentence and you get stuck in the wrong perspective.
When Astal Bee looks back upon his answer later, I'm sure he will agree that the article is not necessary and that your examples are sound.
Yup but now that you said "the objective of the project is developing a framework" is good, it doesn't go well with my findings on COCA
@CowperKettle At least they didn't try to make it seem dramatic with the music.
@Man_From_India How so?
The only argument against that construction is that it is ambiguous in theory (the object is busy developing?), but, in practice, the ambiguity is not there.
@Cerberus se the wiki on shingles I just linked to. TLDR - paraphrasing "No. If your immune system gets weakened, the varicella virus (from an initial youthful chickenpox infection) can breakout as shingles (a different disease/different problems, but caused by the same virus)
@Mitch Then how can the former virus manifest itself as chicken pox, then later as shingles?
I assume the names in the article are the names of viruses.
I see two different names (varicella and herpes), so I assume those are two different viruses.
Or aren't they?
In the morning I quickly ran a search on COCA like this probably "the objective [be] vvg" and found nothing good there. @Cerberus
@Man_From_India google.com/…
Two examples from books.
15:42
@MattE.Эллен so they're related (herpes zoster and herpes A/B/C) but are not the same and have different expressions. VZV gives you chicken pox (which is flu-like plus the blisters), but herpes simplex gives you cold sores and genital warts
Four with "the object is preventing". google.com/…
@Cerberus So in the US insurance is usually awful in comparison to Europe, but I think I only had to pay a $10 copay for a flu shot (it was free at the hospital as an employee)
@Cerberus yes, that's weird
@Cerberus good finding. Btw did you check COCA?
@Mitch That's €10 more than here!
@Cerberus I don't know enough about the mechanism to answer 'how'. I'm just reading that it does do it.
15:48
@Man_From_India Nope, I hardly know what it is, I think a corpus?
@Mitch Nor I.
@Cerberus varicella = herpes zoster = VZV
> Shingles and chickenpox are distinct human diseases but are closely related in their life cycles. Both originate from infection of an individual with the varicella zoster virus (VZV).
@Cerberus yes AmE corpus. And thank you for your valuable comment there under the question.
TIL Swahili is a mix of Bantu and Arabic, and the name is from an Arabic word meaning "of the coast."
I always thought it was a very original African language.
I'm pretty sure that it is primarily Bantu, but with a lot of Arabic vocab. where 'a lot' is very... vague.
ie it is not a creole, just has a lot of borrowings
@Mitch I would surmise that the borrowings mostly involve trade.
15:54
ie there is more evidence that English is a German/French creole (which might be controversial, or it might be acceptable)
@Robusto yeah, vocab about stuff
The point, though, is that Swahili is not Bantu.
I don't think Swahili does any kind of vowel ablaut to get inflections.
@Robusto Oh.
There, with the little I know, I would disagree.
Hmm.
The Swahili people (Swahili language: WaSwahili) are a Bantu ethnic group inhabiting East Africa. Members of this ethnicity primarily reside on the Swahili coast, in an area encompassing the Zanzibar archipelago, littoral Kenya, the Tanzania seaboard, northern Mozambique, the Comoros Islands, and Northwest Madagascar. More recently, Swahili identity is centered around any person of African descent who speaks Swahili as their first language, is muslim and lives in a town on the main urban centers of most of modern day Tanzania and coastal Kenya, northern Mozambique and the Comoros, through a process...
Depending on what you mean by 'is', I would say Swahili is a Bantu language with 20% Arabic vocab, it does not do grammar at all like Arabic and does it a lot like other Bantu languages.
And it doesn't hav a loss of a lot of Bantu grammatical features as one might expect if it were a creole.
I just paper-clipped that from a book I just read.
@Mitch Most odd! Why varicella zoster = herpes zoster?
@Mitch How do you know so much about Swahili?
@Mitch I think lexical items are not insignificant, especially if they comprise 20% of the language.
True.
@Cerberus look man I don't know who mad up these words. Maybe under the microscope they all look like snakes?
4 mins ago, by Mitch
Wikipedia, I know, but it is something.
16:06
@Robusto Sure but 'significant' enough to change its categorization?
That is above my pay grade.
"Significant" requires definition at this stage.
@Cerberus How does anybody know anything that they don't live? I've read about it.
@Cerberus 20% vocab
Recently?
@Mitch Then the discussion becomes meaningless, about a tautology.
In the past couple years?
16:07
OK.
Then how come you read so much about Swahili over the past couple of years?
@Cerberus No I think a discussion can continue if we agree on some things.
@Cerberus Why does anybody read anything beyond the point of a gun? I was interested?
@Mitch There is no point in discussing whether X is significant if you agree that 1) significant means 20%, and 2) X has 20%.
It is a finished syllogism.
@Mitch OK OK.
My expectation is that if you have studied or have grown up with Arabic, you will be able to recognize a few Swahili words but that's as far as learning Swahili will go.
It also needs to be allowed that mere percentages of lexical items says nothing about usage of those items.
@Cerberus But if you translate a number into 'significant' and then use 'significant' in other versions of its meaning then that won't get you anywhere.
@Robusto Yes, everything has qualification. what the frequency of use of any word is, what contexts each word is, etc etc.
16:13
@Robusto Depends on what the percentage really means. Percentage of words found in a corpus? Does the same word count twice when found twice? Etc.
@Mitch Yes, but that is not relevant in the present context.
@Cerberus Oh. I think that is exactly the issue.
French and Latin each comprise ~28% of English words, while Germanic languages (incl. OE) weigh in at 25%, yet about 70% of words used in English are Anglo-Saxon in origin.
@Cerberus Well, not really
Maybe in the capitals it was better.
But in the countryside it must have been bad.
A totalitarian regime is very good at concentrating efforts on a limited number of points.
Context?
@CowperKettle Over what time period?
16:18
"Is Swahili a Bantu language or is it a mix of Bantu and Arabic?"
"The data says 20% of its vocab is Arabic"
"20% is significant"
"If a language has a significant % foreign vocab vs native then it is a mix and not primarily native."
@Mitch Where did you get that?
@Robusto I'm writing it myself as a description of the justification here in chat that "Swahili is a mix".
We still need more data.
Hell, we always need more data.
Yes.
So as a proxy, if all we knew were that 20% vocab of swahili were Arabic, then I wouldn't go so far as to say that Swahili is not Bantu, and that it is a mix of Arabic and Bantu.
only if you want to be accurate. I, for one, want to lie to people, so less data is ideal
16:22
I'd be more likely to say that English is not Germanic but is a mix of French and Germanic.
Dinosaurs and humans cohabited!
ew
@MattE.Эллен You should have your own conspiracy-theory "news" outlet here.
it is in all the drawings
It was a different time, don't judge them by our morals
@Robusto I'll call it faux news
16:23
Already taken.
We are closer in time to T Rexes roaming the earth than T Rexes were to Stegosauruses
@Mitch Then you require definitions.
You need to explain what "be Germanic" means.
Otherwise, it is a meaningless word game.
@Mitch A fact that clearly bothered them. Many T. Rexes were in analysis for years because of that.
@Mitch Yeah, that's funny.
16:29
Also, 20-25% of T. Rex vocabulary came from Stegosaurian.
How archaic.
Some say that *rrrawrrrr was not really Stegosaurian, but leading scholars have traced it that far back.
The Stegosaurs pronounced it *rewwwwrrr but it's the same word.
@Robusto wipes splurted tea off screen
@Mitch I figured you'd like that one.
Famous Gomel (Belarus town) volunteer Ilya Mironov received 25 days of arrest for the slogan "Write letters" on his T-shirt

Q: Correct unicode character for the apostrophe in generic alien names?

John OI am specifically asking about alien names in either science fiction or fantasy stories (novels, movies, whatever). This includes place names and not just names of individuals. It should exclude names of humans in real life, except for comparison purposes. For instance, the family names O'Neill a...

@MattE.Эллен Why would there be a "correct" Unicode character for SciFi writing?
Yeah, please don't accept that here. We've got enough of a trash heap going already.
@Robusto I don't get it either. they're names of imaginary people typed by real people using whatever orthography they like. Why would Unicode get involved?
@Robusto oh, no, I just thought any unicode buffs in the room might want to look
@MattE.Эллен In other words, where is @tchrist now that we really need him?

Q: Are a and ʌ pronounced the same?

Wilder SilvaAs in write vs up or must vs nice. I don't seem to find any difference. Could anyone tell me if there is one please?

I don't even know what this person is asking. Needs "details or clarity" ... not necessarily in that order.
17:00
Yeah, that is a bad question.
17:19
Illustration showing the average increase of living space of working class people in Dutch cities from an one room flat in 1900, to a worker's flat in the 1930s to a Bijlmermeer flat in 1970.
All inhabited by a family.
17:32
Yeah, progress is steady.
Now, however, people in Amsterdam have less and less space per person, because of exploding housing prices.
My mother's family lived in Flat No.1 until 1960. A family of five. In a one-storey shed.
All in a single room.
And without a separate toilet. The toilet was down the corridor.
Quite uncomfortable.
But people were used to it.
And without a bath. They went to the public bathhouse, a big building built for washing many people.
That was also common here.
And these kinds of kitchen.
Guess what the round lid covers.
When they first moved to a two-room flat with an actual water tap and a toilet, my mom (as a girl) used to run multiple times to the bathroom and check out the water tap. You just turn the tap, and water starts flowing.
17:35
Yeah people used to use pumps.
@Cerberus A pot for cooking?
Wrong!
Guess again.
A toilet bowl?
Ding!
Imagine if mother was cooking and father needed to evacuate himself.
Nice, a cozy kitchen/toilet )))
17:36
Quite.
They could chat and see what the other was doing while she was cooking and he was doing his business.
A great read on how people used to house themselves, room-by-room, is At Home: A Short History of Private Life by Bill Bryson.
> - The USA will soon fall due to our counter-sanctions!
- Wash yourself faster, you **cking patriot, they have only switched on the water for half an hour!
A popular meme.
People still have showers in their kitchens here, though in closed cabins.
Contrsankshiy, funny word.
> In even the best houses, floors were generally just bare earth strewn with rushes, harboring “spittle and vomit and urine of dogs and men, beer that hath been cast forth and remnants of fishes and other filth unmentionable,” as the Dutch theologian and traveler Desiderius Erasmus rather crisply summarized in 1524.

Bryson, Bill. At Home: A Short History of Private Life .
> In humbler dwellings, matters were generally about as simple as they could be. The dining table was a plain board called by that name. It was hung on the wall when not in use, and was perched on the diners’ knees when food was served. Over time, the word board came to signify not just the dining surface but the meal itself, which is where the board comes from in room and board. It also explains why lodgers are called boarders and why an honest person—someone who keeps his hands visible at all times—is said to be aboveboard.
Interesting.
That may also be behind the etiquette of never keeping one's hand below the table at dinner?
17:49
Could be.
> Because bread was so important, the laws governing its purity were strict and the punishments severe. A baker who cheated his customers could be fined £10 per loaf sold, or made to do a month’s hard labor in prison. For a time, transportation to Australia was seriously considered for malfeasant bakers. This was a matter of real concern for bakers because every loaf of bread loses weight in baking through evaporation, so it is easy to blunder accidentally. For that reason, bakers sometimes provided a little extra—the famous baker’s dozen.
Although I think the rule is not always observed in Anglo-Saxon countries.
I think I would look askance at someone whose hands were below the table for any significant length of time.
One often sees Englishmen do it at dinner.
It is not considered as sinful there as here!
our rule is "no elbows on the table"
How about forearms?
> Curiously, the one service room not named for the products it contains is dairy. The name derives from an Old French word, dey, meaning maiden. A dairy, in other words, was the room where the milkmaids were to be found, from which we might reasonably deduce that an Old Frenchman was more interested in finding the maid than the milk.

Ibid.
18:23
@Robusto I think those are taboo, too, but less so
18:35
@MattE.Эллен no elbows, no forearms....what do you just hold your arms and hands hovering over your plate?
@Cerberus If you're of such a disposition, perhaps you could get your country to take over and rout the Taliban?
We are not Team America: World Police.
> How do you ask the last soldier to die for a mistake?
Afghanistan was just Vietnam all over again. A mistake.
18:58
@Mitch hands in the air and wait for dessert
@MattE.Эллен Glad to know that one's international!
@Robusto Forearms are fine!
@Robusto Perhaps, but we don't have the resources.
And we didn't invade the country.
@Robusto But that is just what America did.
@Cerberus Neither do we. Not for an endless resource sink like that.
America does, as she has shown us for twenty years.
@Cerberus Agreed. It was stupid then, it's stupid now. Wars don't age like fine wine.
What is more, she could do it at a fraction of the cost, by no longer investing in the failed Afghan army but simply using 10,000 soldiers of her own to keep the Taleban at bay.
19:10
@Cerberus Now you're appealing to the Vietnam fallacy.
Most of the billions expended were a waste.
At least I'm not falling for the Trump-Biden fallacy...
We spend lavishly for weapons that will never be used, but when it comes time to make our people much more secure with sane healthcare programs, we can't be bothered.
@Cerberus I don't know what that is. But all of the trillions we've wasted there and in Iraq were thanks to George W. Bush's feeling the need to have a swagger in his step and a bulge in his pants. I think there must be cheaper ways to give stupid presidents a hard-on.
Yes, the invasion of Iraq was certainly a bad idea.
I have my doubts about the invasion of Afghanistan.
It was also a lie.
Yes.
But, once you have taken over a country, you have taken on a certain responsibility.
19:17
I don't know where you read that. But again, it's easy for you to say after the fact. I think it is and was a mistake, and I don't think it's a good idea to keep on going with a mistake, especially a failed one.
