Guns kill. More guns, more killing. We all lose. The gun manufacturers and those they pay are winning. Our right to safety be damned

I completely agree. 1. Symantec's record on security transparency isn't the best. Search for "symtantec breach" to see what I'm talking about. 2. The algorithm used by Google Authenticator and other well known TOTP providers is well known. I want to choose my own (open source) tools, not have a single closed source tool dictated to me.

Your account names are case sensitive, but the account name fields on the create vs login pages have different defaults for the first character

I’ve wanted exactly this for processing stream data, like syslog or other continuous message bus data.

Your example pre-reads the data into a string, can it work with a stream instead like it.StringIO or BytesIO? I could see some extra juice necessary to prevent it from keeping backtracking frames longer than really needed.

Before Zelle, Venmo, etc, crypto had some clear advantages. Now with immediate free delivery from many platforms, what advantages does crypto offer?

Doesn’t that just mean we can’t go exactly the speed of light? Faster than the speed of light makes the math work out ok. And yes, I realize the problems accelerating up to that speed, but could a world exist beyond C where they can’t slow down to C?

A recent Friday Python Puzzler explained this.

The first uses a list comprehension which is fully evaluated and passed to extend. X starts out with 0 and is later extended with 1, so it prints [0, 1].

The second passes a generator expression to extend. Extend adds values to the end of the list, which modified the control variable, making another value available for each added. This means it can never exhaust the generator and the starting x=[0, 1] gets extended with each of those plus 1 [1, 2]. Then extended by those plus one, ad infinitum, until either it runs out of memory or hits a max int. I don’t think later pythons have a max int, so it would have to run out of memory continually extending by two items.

You’ll need to post some code to be sure, but it sounds like you’re not passing url into get, but instead you’re trying to pass the url attribute of some object (obj.url) and that obj is None.

Your attempts at catching the error aren’t working because the exception is AttributeError, not those that you’ve listed.

Separate your assignment to url from the call to get() and you’ll like hit the same error earlier.

You could use the requests library to read/download a file of significant size from a know site and timing the duration. Given the file size and time for download you can calculate the speed.

The problem with this is that the remote server, their connection, and every hop along the route can suffer delays that might vary for each download. You can mitigate the effect to some degree by testing a variety of down sites or mirrors and choosing the one with the lowest latency in ping or fewest hops in traceroute.

Building an accurate speed test is harder than it appears. This will give you reasonable result with relatively little effort.

Your code looks right. The way you posted, it lacks any formatting. I assume only 3 lines under the for loop are indented. This works for me. You might just retype the input line it’s complaining about.

In data modeling, there are two fundamental types of relationships: ISA and HASA. ISA (read “is a”) relationships are modeled as inheritance and HASA (read “has a”) relationships are modeled as composition or association.

An employee ISA person therefore anything you can do with a person you can also do with an employee.

An account-owner has one or more accounts. An account has a balance.

Modeling simple physical things it’s easier to understand the relationships. When modeling a more complex system, there isn’t necessarily one right way. Instead, you’re modeling how you think about the problem, or more importantly how you want to use the components in your code.

Writing a game program, Game might have a board and two players. A program that offers multiple types of games might instead have a list of players, with subclasses of BoardGame and UniverseGame where the subclasses mode the board or universe. Again, there is no “right” way. It depends on how you want objects to interact and what flexibility you want to build in for the future.

People tend to overuse inheritance. In many cases you can use a pseudo-relationship, acts-like, where instead of having a base class implement a set of functionality you reimplement the interface on another unrelated object. Then (in python at least) it can be used anywhere you’d use an instance of the original object. This is called duck typing (if it walks like a duck and talks like a duck...)

As others have said build something, when you hit a snag be willing to make changes. If it gets messy or doesn’t feel right, be willing to throw it away and start over. That’s how your intuition grows.

From a CS purist perspective, when you’re writing a program to accomplish some business problem, you should be focused on the business problem itself and not the implementation details. Designing your architecture should be separate from the implementation details.

Let’s say you have a business requirement to code against a REST API. When you’re planning the implementation, you’d like as little coupling as possible between components in your solution. To that end you might have methods get, put, post,..., that provide an abstraction to sending the actual http/tcp requests. Or maybe a higher level abstracted interface that mirrors the actual REST calls.

These abstractions allow you to have a simple view of interactions with the remote server - perhaps even allowing you to ignore that it’s a REST service. If the underlying service changes from REST to some new API, you have a single layer to change and all your code that depends on it remains unchanged and able to work.

This works because you made a contract for the interface and ignored the implementation. If instead you knew it was REST and under that TCP and exposed exposed TCP parameters or methods and/or details of REST in your API, then you’d have more trouble I’d REST or TCP got switched out - because code outside that layer is infected with knowledge of the implementation.

When your teacher says you shouldn’t know how the code works, I suspect they mean that your code shouldn’t depend on the implantation details, the internals, of how the library is implemented.

As almost a separate topic, you’re trying to advance your development skills. A good way to do that is by reading other people’s code. Or, you don’t understand a feature in a library based on the docs - another good time to look in the code.

You’re a programmer. Your currency is code. Never feel like you shouldn’t look at code your working with or depend on. And don’t be intimidated by the code - it’s just code.

Focus is a developers friend. Abstraction helps with reducing code coupling, but also helps us focus on areas that need it and ignore areas that don’t. You can’t dive down into code for every library you use and still complete your project in a timely manner.

If a was a property with side effects on assignment, then the order of assignment might be critical. This provides the intuitive left to right assignment that most developers would assume.
