The URL when I first clicked this was the GitHub release notes, which is far more informative and apropos to the HN audience than either the TF landing page or vague VentureBeat pseudonews.

I agree that latency and detail of feedback is an enormous problem with this sort of partially-guided coursework. However, it's a generalized problem with higher education, not specific to GT, in that when implemented effectively it&#x

I did a resident MS CSE around the time they started the online program. While for the classes that were also available online they seemed equivalent (usually just recorded versions of the same class), there is one big caveat: most of the c

Language shapes perception shapes language, so it's absolutely worthwhile to be vigilant and critical about the idioms we endorse by adopting, especially for engineered phrases (e.g., "right to work").

That's an odd example, given most video games are written in memory managed languages for performance reasons. Typically an allocation pool would be used for that case because there's some bound to the number of simultaneously all

A big non-safety selling point of Rust for me is a systems language with the tooling and ecosystem of a modern dynamic language. Dependency management and composition is a necessary part of complex programs, but a tedious, painful timesink

I like my 2nd gen Moto 360 as a watch, for its aesthetics, and as a simple notifier, but almost everything else on it is beyond broken. Just trying to check the weather takes 20+ seconds and fails half the time, even on wifi. Pull out the p

A complexity measure is a measure of complexity over a model. Mostly we talk about input size models, but we can (and do) talk about other models. It isn't a question of complexity scaling vs. time scaling, but of complexity scaling ov

We "over-complicate" ISAs for the same reason we're constantly adopting new vocabulary: there is efficiency in specialization. Good design is not about simplicity; it's about managed complexity. > - Why do compilers n

It's not a question of intelligence, but of attention. Few crashes are caused by wrong inferences; most are caused by lapses in attention or impaired judgement. Computer systems do not necessarily suffer from those.

Yours is a great example of what graph DBs should be good at, but many self-styled graph DBs out there at the moment are not. Graph DB means to me only two things: index-free edge traversal and scalable built-in graph operations. While thes

While I don't think Steam machines are DOA quite yet, they target an already difficult niche for which Valve's indecisive approach is ill-suited. The lack of marketing and immaturity of platform and user experience mean the most v

My favorite is pop science reporting never linking to the press release for the publication that it's pulling from, much less to the publication itself. Often the title of the article isn't even mentioned.

Good point -- I was talking in the context of bulk upserts but didn't make that explicit.

by aschampion 11y ago
Neat library. Just to note that this approach to fake upsert is not safe to concurrent sessions. There were exactly two concurrency-safe ways to implement upsert prior to 9.5: 1. An exclusive lock on the table, which is slow as hell 2. A PG
