Dice (typically) do not have a memory, so whatever happened yesterday will not influence what happens today. If you roll it daily, your chance of surviving at least N days is (215/216)^N, for the specific case of "rolling three 6

Well, a degenerate Merkle tree is a list (any degenerate tree is a list). As a consensus mechanism, I could potentially think of many ways of getting that, but none that are both efficient and trustless. As-is, the cryptocurrencies we'

"Blockchain" is basically just a Merkle tree with a branching factor extremely close to 1. That is, in and of itself, neithre inefficient nor bad. However, pairing that with a proof-of-work consensus mechanism is incredibly ineffi

My understanding is that it's still borg. All the cool features from omega were backported into borg, since they were needed to support (insert product here), and in the end some of the omega team got an OK to write and open-source kub

At my previous workplace, one of the clusters I herded was 60-odd (physical) machines, 72 or 96 cores (honestly can't recall at this point) and 384 GB RAM (IIRC) per physical server. But, that place was a wee bit strange, in that we ra

Kubernetes is complex because coordinating potentially hundreds och machines with potentially tens of thousands of containers so that it all flows smoothly, expediently, and allows change is a complex problem.

There's a world of difference between "simple configuration needs" and "complex configuration needs". I will take a kubernetes deployment manifest as an example that you would want to express in a hypothetically per

Anecdotally, the DEC Alpha was the first chip to move from "clock is provided at the edge of the chip" to "clock is provided in the middle of the chip", due to a desire to minimise the skew from one edge of the CPU to th

Due to a recent-ish move, I have gone from ~20 years with a gas cooker to induction (with about 6 months of halogen in-between). Induction is pretty good. It lacks the visceral feedback of "how hard am I driving this specific ring&#x2F

Well, "passive cooling" means that it requires no external power to cool. Doesn't necessarily mean it's normally plumbed into the circuit. Most probably it would not normally be, as the passive cooling would definitely d

A well-written commit message should explain "why", this may partially consist of linking to external things (bug tickets, whatever). Although it is probably important to have enough of a "why" that the reviewer can make

Was the developer doing something "outside what they should be allowed to"? No. It's their package. I would argue that intentionally introducing a breaking change (I would count "go into endless loop" as "no lo

It depends. If your monolith requires, say, 16 GB to keep running, but under the hood is about 20 pieces, each happily using less than 1 GB, tripling only a few of these means you may be able to get away with (say) 25 GB. Whereas tripling y

depending on your calendar tooling, you may be able to have calendar events shared between multiple calendars. And I do understand the whole "not wanting more devices", although it can lead to having a harder time separating work

My xmas gift to one of the other teams in the company was improving one of their alerts, so that it fires when there is an observable problem with the monitored thing, instead of firing pretty much constantly. Makes the alert more useful an

Let me guess, someone at some point said Sarbanes-Oxley? Under that restriction, the team running the app must not have access to the app's codebase. And the team writing the app must not have access to the production configuration (an

They're bits, in groups of three. rwxr-xrwx would be "111, 101, 111", so 7, 5, 7. I may be odd, but I don't find reading "small numbers" in binary to be much harder than reading "small numbers" in dec

The archetypical "microservice" ecosystem I am aware of is Google's production environment. It was, at that point, primarily written in C++ and Java, neither very famous for being dynamically typed. But, it was a microservice

Go code that requires language (or stdlib) features first present in Go v1.n will not compile with any version of Go 1.m, m <= n. There have been a few of these (modules, soft-launched in (IIRC) 1.11, there were one or a few in 1.15, now

For at least some languages, it might even be important to have access to older versions of a file. As a concrete example, Go imports (at least for module-enabled code) is version-locked and the HEAD of the referenced code may no longer be

If the usage terms say "do not use in any critical applications", I would've thought that the responsibility for using the code in that fashion woudl be squarely with the entity that did the integration? It'd probably be

"Does my GPU need to talk to my mouse"? That is definitely one of those "it depends on the system". On at least one DECStation model, sort of (depending on how you define "GPU"), the mouse interface is actually

As long as you stay away from compiler-dependent, platform-dependent, and/or undefined behaviour, you should be fine. Main problem is that a surprising ab´mount of "looks normal" code is actually UB.

A non-drone player was necessary, as Azad would never have acknowledged defeat by a drone. But, defeat by a human accomplished the Culture's goal and Gurgeh was the best bet (or at least the best available one) on the desired outcome.

In some cases, you will be escorted off the premises immediately, then paid to stay at home until the end of your notice period. This is mostly for people with somewhat sensitive jobs, though (research, sales, some management positions) and
