Travel to Europe (Spain) while remote working from USA-based company [duplicate]

This question already has an answer here:

  • As a US Citizen, if I'm visiting the Schengen region, can I “work from home”? [duplicate] 1 answer
  • Do I need a visa to work remotely in Europe as a Canadian citizen for six weeks? 1 answer

This question mentions some of the laws and challenges and what have you of working remote from Europe to USA, So does this one, but how about the other way around? If I am working remotely in an USA-based company, living in the USA and I wish to travel to Europe for a short period of time (a month or less), would there be any current issues with Visas or the Visa Waiver Program? Or is it safe, providing enough proof that there’s no wish to stay?

cheap air travel tickets through blind company

A couple of years ago there used to be a website where given the origin/destination and travel dates they would answer, after some time, with a price offer, in theory, beating market prices. The trick here was that you wouldn’t know the company before accepting.

I don’t remember the name of the website. Is there still such a service?

How can a company tell if my password is similar to the previous 5 passwords?

Closely related (but not a duplicate): Company can tell if new and old passwords are too similar. Is there a security problem?

Also closely related (but not a duplicate): How can a system enforce a minimum number of changed characters in passwords, without storing or processing old passwords in cleartext?

A particular company (I won’t say which one) requires that my password not be similar to any of the previous 5 passwords.

According to the linked questions, when they check to see if your password is too similar to the previous one, they just force you to enter both the old and new password and compare them that way. I understand that, and there doesn’t appear to be any security problem with that.

However, the company in question actually compares my password to the previous 5 passwords, none of which I enter. How might they be doing this? Should I take this as evidence that they’re either storing my passwords in plaintext or that they’re using a really weak hashing function, or is there a legitimate way that they could do that without potentially compromising my password?

The linked answer in the second linked question briefly alludes to this issue but doesn’t really fully address how they might be doing this or how big of a security concern it is.

Am I scamed? FA exchange trading company is fraud? They are requesting taxes

Are those thieves? https://www.faexchange.com/ I have created a balance of BTC with them and they now request to pay taxes in order to be able to withdraw my profit so I am worried about and wonder why they do no keep the taxes from my earnings?

Additionally to report that they do not allow any withdrawal until they receive the taxes however I have found out that they are included at “bad list” https://badbitcoin.org/thebadlist/index.htm I do not have a bitcoin wallet; but FA exchange never advised me to open one. Should I create one and request from them to transfer the bitcoins there? What about the taxes in this case, should be deducted?

Any kind of advice on how to continue further on to cash/ redeem my Bitcoin would be usable.

Can company corporate building guest wifi track my sites visited on my phone

To give context, I’m not too familiar with computers an IT terminology, so please excuse my mistakes.

I work in a building where they provide guest Wi-Fi. Before you log in, you have to sign their terms and conditions (don’t do illegal stuff, etc.). I did go on a “bad site” on my cell phone and saw that it was blocked. Can this be traced back to me?

I’ve done my research and read into MAC addresses linked to cell phone hardware. Does that mean an IT administrator would be able to trace it back to me personally or would they just see that “someone” tried to access a blocked site?

I’m worried I could get in trouble for what I have done.

Is my company merging branches wrong?

I recently came across an msdn article about branching and merging and SCM

article: https://docs.microsoft.com/en-us/previous-versions/aa730834(v=vs.80)

In the article they say ‘big bang merge’ is a merging antipattern:

Big Bang Merge — deferring branch merging to the end of the development effort and attempting to merge all branches simultaneously. 

I realized that this is very similar to what my company is doing with all of the development branches that are produced.

I work at a very small company with one person acting as the final review + trunk merge authority. We have 5 developers (including me), each of us will be assigned a separate task/bug/project and we will each branch off the current trunk (subversion) and then perform the development work in our branch, test the results, write documentation if necessary, perform a peer review and feedback loop with the other developers, and then submit the branch for review + merge on our project management software.

My boss, the sole authority on the trunk repository, will actually defer all of the reviews of branches until a single point in time where he will perform reviews on as much as he can, some branches will be thrown back for enhancements/fixes, some branches will merge right into trunk, some branches will be thrown back because of conflicts, etc.

It’s not uncommon for us to have 10-20 active branches sitting in the final review queue to be merged into trunk.

We also frequently have to resolve conflicts in the final review and merge stage because two branches were created off the same trunk but modified the same piece of code. Usually we avoid this by just rebranching off trunk and re-applying our changes and resolving the conflicts then submitting the new branch for review (poor mans rebase).

Some direct questions I have are

Are we exhibiting the very anti-pattern that was described as the ‘big bang merge’?

Are some of the problems we’re seeing a result of this merge process?

How can we improve this merge process without increasing the bottleneck on my boss?

Any other insight into this situation would be appreciated.
