## covid 19 – Is eating permitted in La Guardia airport airport nowadays?

I haven’t been to LaGuardia recently but in other airports eating and drinking is allowed and you can buy snacks and water/drinks. The expectation is that you remove the mask for short periods while eating & drinking and do so at least 6 feet away from anyone else. Most people I saw did comply with that.

In Newark (EWR) one sit down place was open, the tables were far enough apart so that people could eat without wearing a mask.

Practices in lounges vary greatly: “closed”, “no food or drink”, “only pre-packed snacks or water, but must eat outside”, “some food and drinks for consumption inside but no alcohol”, etc.

Caveat: Details vary with the specific airport & terminal and regulations do change quickly with little or no notice.

## covid 19 – Is eating permitted on Southwest Airlines today?

From Southwest’s FAQ—When the Federal law requires Customers to wear a mask (emphasis added):

Customers will be required to wear a mask over their nose and mouth at all times during their Southwest travel experience—while checking in, boarding, while in flight, deplaning, retrieving baggage; and any other time they may engage with a Southwest Employee or another Customer. Customers are required to wear a mask in order to board the plane.

The following are times when a Customer may need to briefly remove their mask:

When necessary for identity verification purposes such as during Transportation Security Administration screening or when asked to do so by our Employees or any law enforcement official

While eating, drinking, or taking oral medications. Prolonged periods of mask removal are not permitted for eating or drinking; the mask must be worn between bites and sips.

While communicating with a person who is hearing impaired when the ability to see the mouth is essential for communication

If, on an aircraft, wearing of oxygen masks is needed because of loss of cabin pressure or other event affecting aircraft ventilation

If unconscious (for reasons other than sleeping), incapacitated, unable to be awakened, or otherwise unable to remove the mask without assistance

## Is eating permitted in LGA nowadays?

What is the current policy concerning eating in the domestic terminals at LGA? (Obviously, one cannot wear a mask continually while eating.)

I will be flying Southwest, so I am most interested in Terminal B at LGA.

Thank you.

## usa – Is it permitted to look for a job while visiting the US under the Visa Waiver Program?

So there are really two questions here:

1. What do laws and regulations say about VWP visitors looking for work during their stay in the US?
2. Practically speaking, if I want to visit the US to look for work, should I apply for a B-1/B-2 visa instead of trying to use VWP?

To the first question, the answer is that the allowed activities on VWP are exactly the same as the allowed activities on a B-1/B-2 visa. However, one may not apply for an extension of stay, change of status, or adjustment of status while on VWP. (There are some exceptions to this rule.)

If you don’t believe me on this, here are the legal sources.

The Immigration and Nationality Act (INA) §217(a) lists the requirements that are imposed on the visitor themselves. There are various requirements that don’t apply to B-1/B-2 visitors (e.g. must be in possession of a round-trip ticket, must not have visited Iraq or Syria, and so on). However, the sole requirement on the allowed activities while in the US is:

(1) The alien is applying for admission during the program as a nonimmigrant visitor (described in section 1101(a)(15)(B) of this title) for a period not exceeding 90 days.

The Foreign Affairs Manual, while not binding, reflects the State Department’s official position regarding the appropriate uses of various visas. Regarding VWP, it mentions here:

An alien who is a national of a participating VWP country does not require a visa, provided the alien:

(1) Is applying for admission as a nonimmigrant visitor, as described in INA 101(a)(15)(B);
(2) Seeks to enter the United States for a period not to exceed 90 days;

and:

Nature of VWP Travel:

(1) Maintenance of Status: An alien admitted to the United States under the VWP:

(a) Is admitted as a visitor for business or pleasure for a period not to exceed 90 days;
(b) May not engage in activities inconsistent with status as a visitor;
(c) Is not eligible for an extension of stay in the United States;
(d) Is not eligible for adjustment of status to that of a lawful permanent resident alien (other than as an immediate relative as defined under INA 201(b) or under the provisions of INA 245(i); and
(e) Is not eligible for change of nonimmigrant status.

The CBP Inspector’s Field Manual may be more directly relevant to this situation since most ESTA applications are not manually reviewed by someone at the State Department but the determination of admissibility will be made at the port of entry. Regarding VWP, it says:

The Visa Waiver Program (VWP) permits nationals from designated countries (listed in 8 CFR 217.2(a)) to apply for admission to the United States for ninety (90) days or less as nonimmigrant visitors for business or pleasure without first obtaining a U.S. nonimmigrant visa (USNIV).

“Business or pleasure” is the same as a B-1/B-2 visa.

It also mentions:

An applicant for admission shall not be admitted under the VWP unless the alien convinces the examining immigration officer that he or she is clearly and beyond doubt entitled to be admitted and is not inadmissible under section 212 of the Act. The conditions for admission are specified in section 217 of the Act and 8 CFR 217. All VWP admissions are for 90 days unless the applicant’s passport is valid for a lesser period, in which case the period of admission would be until the expiration date of the passport for those countries on the 6-month list. In the cases of those countries not on the 6-month list, the applicants would not meet the documentary requirements in Chapter 15.7(b), Documentary Requirements, and would be inadmissible under the VWP.

This doesn’t add anything beyond the statute and regulations which already specify that VWP applicants may engage in the same activities as B-1/B-2 applicants. The “clearly and beyond doubt” standard applies to all nonimmigrant applicants for admission.

In short, if you believe that B-1/B-2 visa holders are allowed to enter the US to look for work, you should believe the same about ESTA holders.

Regarding the second question, my opinion is that you should just try to enter under VWP. It’s very unlikely that they will tell you “no, you have to apply for a B-1 visa for that” since they are supposed to know that the allowed activities are the same. If they do refuse you admission under the VWP, you are unlikely to be approved by ESTA in the future. However, that would also be the case if you were refused admission under a B-1 visa. So, to preemptively apply for a B-1/B-2 visa now would be pointless in my opinion. If you are reading this during the COVID-19 pandemic, trying to apply for a visa would needlessly inconvenience you because many consulates are not operating at full capacity anyway.

## file permissions – “[ErrorException] chmod(): Operation not permitted” running “composer update”

I’m running Magento 2.4.2 and I’m using Composer v2.0.11. 2 days ago, after running, as usual, composer update, I suddenly received this error:

``````(ErrorException)
chmod(): Operation not permitted
``````

You can see `composer update -v` output down below:

### What I tried

• I tried to apply `chmod -R 777 .` and `chown -R www-data:www-data .`
• I tried to apply chmod u+x bin/magento

Any ideas?

## ergodic theory – Number of permitted words up to permutation in a subshift

Let $$A$$ be a finite set and let $$X subseteq A^{mathbb{N}}$$ be a subshift. Let $$mathcal{L}_n$$ denote the set of words of length $$n$$ appearing in $$X$$. For a word $$w in mathcal{L}_n$$, one can define its empirical distribution to be the probability vector $$P_w := left( frac{N(a | w)}{n} right)_{a in A}$$ where $$N(a | w)$$ denotes the number of occurrences of the letter $$a in A$$ in the word $$w$$. I am interested in the quantity $$T(n) := # { P_w : w in mathcal{L}_n }$$ (equivalently, $$T(n) = #(mathcal{L}_n / sim)$$, where $$sim$$ is the equivalence relation on $$mathcal{L}_n$$ that declares two words to be equivalent if they are permutations of each other).

More specifically, I’m interested in subshifts with the property that $$limsup_{n to infty} T(n) = infty$$. Is there a name for this property? Are there any more commonly known conditions that imply this property?

Some examples/non-examples for intuition:

1. $$X = {0,1}^mathbb{N}$$. All words are permitted, so $$T(n) = n+1$$.

2. $$X subseteq {0,1}^mathbb{N}$$ is the SFT defined by forbidding the word $$11$$. Words of length $$n$$ can have up to half of their entries be equal to $$1$$, so $$T(n) approx n/2$$.

3. $$X$$ is the orbit closure of $${ x in {0,1}^mathbb{N} : x_{2i}x_{2i+1} = 01 text{ or } 10 text{ for all } i }$$. Any permitted word $$w$$ of length $$n$$ has both $$N(0 | w), N(1 | w) in (n/2 – 2, n/2 + 2)$$, so $$T(n) leq 5$$ for all $$n$$.

## publishing – I want to make a video game based off of Dungeons and Dragons. How much am I legally permitted to use?

I want to make a video game based off of Dungeons and Dragons. It’ll be a top-down RPG with similar battle and class mechanics. But I’ve been planning out more, and seeing how much I’m copying. How much am I legally permitted to use? I am awayer of the SRD, but don’t understand it fully. Is it like a book of what I’m allowed to use?

## Is someone else’s surgery a legally permitted reason for international travel from the UK?

Your need to see a person before a surgery, or to bring some people to see that person, is not a medical emergency. Her need for the surgery, may be, but it is not her who wants to travel. I doubt you will get an exception.

Where you might have a chance is, it says on your link that you can travel for the same reasons you can leave home, and you can leave home

to visit someone who is dying or to visit someone receiving treatment in a hospital, hospice or care home, or to accompany a family member or friend to a medical appointment

Now, it also says you can leave home to exercise, and I’m sure you couldn’t get permission to fly to another country to exercise, so this isn’t a guarantee of success, especially since this “major surgery” is one that can be postponed a few times already.

I can’t see a way for you to apply for permission to travel; it looks like you just do it and perhaps argue with someone at the airport about it? This looks too risky to me.

My personal definition of emergency travel (under which I did travel internationally in November) is: does any cost, quarantine or other issue mean I won’t go, or will I go no matter what? I will go no matter what, then I go. In my case this involved two separate two week quarantines, one of which cost me over \$5000, and Covid testing. Didn’t matter, I had to go. If your need is not that urgent, then you know you should not go.

## germany – What are the “legally permitted reasons” for international travel FROM the UK?

I have a flight ticket from the UK, to Costa Rica, with a connecting flight in Germany (in March). The airline is Lufthansa.

Costa Rica is allowing international travellers in, however, the UK is currently in lockdown and has put out restrictions on leaving your home. The current rules the that UK Government has put out are not very clear:

You can only travel internationally – or within the UK – where you first have a legally permitted reason to leave home. In addition, you should consider the public health advice in the country you are visiting.

If you do need to travel overseas (and are legally permitted to do so, for example, because it is for work), even if you are returning to a place you’ve visited before, you should look at the rules in place at your destination and the Foreign, Commonwealth and Development Office (FCDO) travel advice.

Additionally, the travel info page specific to Costa Rica says:

Commercial flights are not running normally. United Airlines, Iberia, Air France and Lufthansa are operating some flights and other airlines are resuming operations on certain dates. Check with the airlines or a travel agent.

Supposing that these rules are still in place in March, can I travel to Costa Rica for tourism purposes? I cannot find a list of the “legally permitted reasons” anywhere on the GOV website.
