Oh god, there is some terrible advice in that article. 1. Don’t wrap errors, log. Errors have two purposes - control flow for your application, and information for the developer and operator. If you are already logging the flow of your prog

Another set of masterful distributed system engineers you can look at are the US founding fathers. Like any implementation, it's far from perfect, but I marvel at a system of government with enough fault tolerance, failover, and backup

you don't need a range or a channel to iterate over a collection or read a stream to the end.

by tedsuo 11y ago
A point often missed by new Go programmers is that channels are only for select. In other words, channels are a primitive for handling nondeterminism at the runtime level, not a general purpose queue. If there is no select statement, there

All that internet, and the android tablets are still just sitting on the wall where the light switches used to be. What's the cost in hardware and electricity to move from light switches to android tablets for an entire hotel?

The translation of the compiler from C to Go was a mostly mechanical transformation, specifically to prevent any changes in the resulting compiled programs. Go compilation is getting better all the time, but the switch itself did not change

I kind of did an eye roll at the breathless language in the announcement. I'm trying to unpack that reaction, because I actually really enjoy the first-principles approach that they have taken with their work. I think, perhaps, it&#x2

btw for the record I don't think there's something wrong with making small packages like this, just that I'm more likely to copy over a function or pattern that I like into my codebase, rather than bring in a dependency.
47.
by tedsuo 11y ago
Simply put: dependencies are code, and code comes at a maintenance cost. Thin abstractions, such as a this library, can be replaced by a function or two, which is a lower maintenance overhead because there is less code, you wrote the code,

The term "Data Lake" has been a rich source of puns and riffs at work. You can trawl through it for weeks without finding anything; it's polluted with industrial runoff; you can hide a body in it... Fun, but like the "c

If what you are passing is a pointer, then the value of the pointer (an integer) is copied. So pointers are passed by value. "Pass by reference" means that the runtime will convert what looks like an instruction to copy a value (

The OP's complaint about Go's type system seems to mainly be that memory allocation is explicit. Go is always "pass by value", and it's true that I've watched developers struggle to grasp the full ramifications

The only issue I have with raft (besides bugs in the various implementations I have to deal with at work) is that it is not yet proven to truly be simpler than Paxos. In other words, is it a genuinely simpler algorithm that provides the th

Systems such as Go's goroutines, or clojure's core.async, or objective-c's GCD all solve the same concurrency problem while still allowing you to saturate all of your cores from a single process. This allows you to get around
