Why do 2019-era email clients [(+/-) a few years] often allow you to delete or enter new destination addresses, but not fully edit them?

Suppose that you are writing an email. You mistype someone’s address in the “To” field. For example, maybe you write, “john.reed@blah.com.” Before sending the email, you remember that that person spells their name in a funny way. You want to delete the letter “H” in “john.” The correct email address is “jon.reed@blah.com”

In a significant number of present-day email clients you cannot edit an email address already entered into the “To” field. Once you press enter or shift the keyboard focus to the body of the email, the “To”-address changes. The user interface changes what you have typed into something which can be deleted/removed, but not edited. This is also true of the carbon-copy fields. If you mistype someone’s email, you have to delete the address completely, and re-type it. For many email clients, left-clicking on the email address might delete it, but it does not enable text editing.

I am talking about the front-end of the interface, not what’s under the hood. What is weird is that in the years from 2000 to 2010, editing a destination email address was trivial. In most email clients, the “To” field was a text-box. You could click anywhere inside of the “To” field and type almost anything you liked. The backspace key worked fine; the delete key worked fine; anything.

Features do not become popular in multiple competing companies user-interfaces, unless those features are an improvement over the old way of doing things. There must be a rationale for disallowing users from editing email addresses previously typed into the “to” field. Technically, you can edit them by deleting and re-typing from scratch, but hopefully my meaning is apparent. What is the thinking behind this? Is it a matter of making “the common case” fast? Which user-cases are faster/easier using the (new or delete) style of design instead of the old (edit text) style of design?

Minimum number of scenarios to run to fully test a page

I run a testing application that, using Selenium, runs testing “scenarios” each of which visits a bunch of pages on a website. Each page is modeled by a Java file that contains locators, each of which are used to locate certain elements on the page maybe to verify that they exist or, beyond that, that they work as intended. Some elements may always show up, and some may only show up depending on the scenario you are running. Let’s say the page we would like to test in question is the “login” page, and we are talking about all the scenarios that visit that page.

Bear in mind, some scenarios may visit the login page, but only a small subset of those scenarios are actually intended to test the login page.

Let’s say each page is modeled by a Java source file that contains a bunch of locators intended to locate elements on that page.

Each scenario is intended to test a different overall functionality on the website, but as far as the login portion of each scenario is concerned, multiple scenarios might be totally redundant (only one of these redundant scenarios need to be run to achieve the exact same level of interaction). Let’s say one set of redundant scenarios only minimally enters a username/password and then clicks the log in button. So our Java page always has the exact same sets of locators locating the same elements and not locating any elements for those redundant scenarios.

Let’s say 100 of your scenarios visit the login page. Let’s also say you ran all 100 scenarios to fully interact with that page, but only 10 of them needed to be run to achieve the same thing IE only 10 needed to be run to fully test the page.

Let’s say each locator in the Java file modelling the login page is marked with the scenarios where it successfully located an element on the page. Each locator could have anywhere from 1 to 100 scenarios tagged to it.

Having already run the 100 scenarios, how do you go about knowing what those 10 scenarios are for future benefit? What sort of algorithm would achieve this? Thanks!

What are the steps of making a fully undetectable piece of malware?

I’ve been recently taught how antiviruses work. I know that there is more to it but they basically have a list of known malware that they have encountered and every time they scan, they check if their database content matches the scanning files (heard this in an algorithm & data structures class).

Now my question is, what are the steps and things to consider when an attacker wants to make a piece of malware look eligible?

Should the malware be brand new so no-one has ever had an encounter with it, are there practices that take down the previous assumption?

Google Sheets row minimized to almost nothing when no data is present but needs to auto expand to be fully seen ONLY when data is present

I’ve got a Google Sheet I’m creating for settlement purposes and I have 8 variables that only get used sometimes. Each variable has its own line devoted to it. For example, this load has a scale charge that is visible in the image I posted (but the other 7 rows are blank in the Row 14-21 range).

The data is getting pulled in from a master sheet but I’d like the empty rows to be of MINIMAL HEIGHT by default and then expand ONLY IF any data is actually present to be displayed for a particular variable.

Why do I need to do this, you ask? For space saving purposes for printing since most settlements will have multiple loads. I’d prefer not to leave 8 lines of BLANK SPACE fully expanded all the time for each load for paper-saving & aesthetic purposes. Any ideas?
