No tests can be better than a bunch of brittle mock object tests that don't test anything important. Thankfully it's very easy to delete them. If changing one line of code regularly requires me to update mocks in 100 test cases,

Correlation is not causation. Without a proper randomized trial, these observations aren't worth much. The sort of people that keep their Tdap vaccination up to date likely do other things that reduce their risk (or are just in a bette

The USB host controller does the polling in hardware. The cpu does not get involved until a key is pressed (the host controller can interrupt the cpu, telling it that new data is available).

The histograms are useful on their own (visualized as a heatmap). If percentile lines are necessary (and they often aren't), I prefer to overlay them on top of the heatmap so it is clear where the bucket edges are.

Some observations after using many different testing philosophies on many different teams in the past 20 years: 1. Unit tests for code with no side effects (code that takes well defined input and produces well-defined output) are easy to wr

It does say that, but I'm still skeptical. Shouldn't the total number of beds in use also be skyrocketing along with the Covid number? Also: ""In ICU” numbers include people testing positive for COVID-19 and people who a

Incrementing an atomic counter every time a reference is copied is a significant amount of overhead, which is why most runtimes prefer garbage collection to reference counting (that, and the inability of referencing counting to handle cycle

I'm not super familiar with Swift, but I don't see how it could be memory-safe in a multi-threaded context without some sort of borrow checker or gc. So I think it is rejected by question #2.

If it can really guarantee single-digit microsecond pauses in my realtime thread no matter what happens in other threads of my application, that is indeed a game changer. But I'll believe it when I see it with my own eyes. I've ne

By complicated I guess I mean "lots of types". Static typing makes up for its cost once I can't keep all the types in my head at the same time. Point number 2 excludes pretty much all network-connected software, and that&#x27

My language selection checklist: 1. Does the program need to be fast or complicated? If so, don't use a scripting language like Python, Bash, or Javascript. 2. Does the program handle untrusted input data? If so, don't use a memor

It depends on your camera's low light sensitivity and how much noise you can tolerate. A cheap prime lens will let in an order of magnitude more light than a cheap kit lens. And some folks want that creamy bokeh effect behind them.

Ignore the drama. The language in its current state is great, and will survive bureaucratic spats. Other languages may be more ergonomic or have more batteries included, but none of them can offer the holy grail of memory safety without gar

We've had significant house price inflation for years due to insufficient supply. I want CPI to increase similarly, along with wages. If housing prices stay the same as today (in dollars) the house buying power of a young person will b

In order for young people to have any chance at the same quality of life of their parents, the "real" value of housing needs to come down to at least 50% of the current value. The only way to accomplish this without wiping out tho

10GBASE-T is power hungry and unreliable, but dirt-cheap 10GBASE-LR and 25GBASE-LR transceivers work great up to 10km. If only they could figure out how to fit the transceivers into mobile-friendly packaging. But for a workstation they&#x27

Unfortunately, 10G serdes and >50kLUTs are table stakes to run the applications I have in mind...I think we're a long way from officially supported open toolchains for medium-size FPGAs.

If we could get similar momentum we have with gcc and LLVM behind projects like yosys and nextpnr, FPGAs would be much more useful and likely be a larger market overall. I'm willing to personally donate 10k a year to projects like thes

I wonder how much of this discrimination is due to housing inequality. I suspect many young programmers resent paying $3500 a month rent to a landlord who bought their property for 75k 20 years ago. Denying jobs to that generation might be
