And then consider whether the point of the class is to test smarts, or something else.

I’d expect that’s not the intent of most undergraduate degrees.

Wouldn’t you be able to run a higher clock-speed simulation, and therefore compute the sound ahead-of-time, on a digital device?

in general, the bar has fallen. it is not limited to design.

when you find these kinds of bad decisions permeate, you can usually point to the incentive-setters: leadership and shareholders.

1. Assume a range of values

2. Assume a fair probability function for sampling over the range of values

The estimated size is the %-of-hits * the total range of values.

In the original example, we are testing weather using the previous day’s weather. We may be able to model using whatever correlation exists between the data. This is not the same as accurately predicting results, if the real-world weather function is determined by the weather of surrounding locations, time of year, and moon phase. If our model does not have this data, and it is essential to model the result, how can you accurately model?

In other words: “Garbage in, garbage out”. Good luck modeling an n-th degree polynomial function, given a fraction of the variables to train on.

Likely because Apple themselves provide an emulator that accommodates most developers’ needs.

No need to reinvision the rest of the auth flow if you just want to add hashing to reduce DB load.

> This pattern can be useful for offloading common client connectivity tasks such as monitoring, logging, routing, security (such as TLS), and resiliency patterns in a language agnostic way. It is often used with legacy applications, or other applications that are difficult to modify, in order to extend their networking capabilities. It can also enable a specialized team to implement those features.

Not surprised this is a Microsoft page, given their legacy of long lifetime support for their software products.

It’s not for microservices, but rather for software maintenance of systems that other vendors would consider past EOL.

Notably Signal employees do not get equity, so the salary must be higher to remain competitive.

Signal is probably the hardest class of product to build. Name an optimization/distributed systems problem, they probably have it. And quite literally, a Signal bug could jeopardize an activist/journalist’s life.

So for a <$200k salary and no equity, how many world-class engineers do you think you could hire?

I simply wouldn’t trust the product, if it had mediocre engineers.

Being able to switch between two accounts seems useful in the context of:

1. A recruiter signing out in order to sign into the profile of their CEO/Eng Director to send recruiting messages on their behalf.

2. A marketing person signing out in order to sign in to the company account.

It never helps the second-place bidder. I’d argue “handicap” is deceitful.

But actually, the given solutions are mostly communication-focused, and the automation is to aid in that.

Good read.
