Eclipse IDE (Java) can run your project, even if it doesn't all compile. I expect this must be fairly common among IDEs with incremental compilers. You can run valid sections & gradually progress the complete correctness. No need f

I've had extensive experience on both sides of the fence -- working on apps within existing frameworks, and also maintaining custom frameworks & libs for apps using those. Unfortunately I find this article of very little value. The

As an architect working on maintenance & refactoring, I find regular value in being able to understand the context (issue tracker ticket) in which a commit was made. Also more than mildly useful for devs doing porting work. Commit comme

Capturing is not supported. That eliminates many normal regex usecases, where you want to be able to capture & interpret the data.

The right abstractions? React's functional components are a monument to concept over practicality, and the overall ecosystem is a hot mess. Populating initial state should not be a difficult special case. Handling state changes should

I laughed at the authors CS Salad, B Noodles and C Fajita -- Google in that case having parsed a cafeteria lunch menu.

I agree -- the OP said space for all the separate HTTP response variations might be an issue, and "With a smart enough storage format all of these could be solved". I think he misses that storing HTML and having a webserver turn t

Failing and aborting the request/ user action is the general & correct response to an error. Retrying is relevant for a specific small segment of callsites dealing with unreliable network or hardware interactions. This fact and kno

Toyota vehicles were investigated in the 2000s for claimed "unintended acceleration" causing up to 89 deaths. This is an analysis conducted by Michael Barr finding potential flaws in the electronic throttle control system. Michael

Well, unless you care about disaster recovery or availability. For most business applications used by more than one user there are usually some expectations that data will be retained and the application will be available.

It works 24/7, I guess. Reliability is the key -- it stays running. It's got a vast array of third-party libraries available. It performs pretty well even in a low-latency environment. Developers can spend time solving actual busi

Good question. The example message is adapted from a fast-moving innovation stream; it's an example of moving quickly and getting a lot of major work done. In a more mature area, pace of work could often be slower and commits more gran

Interesting topic. From my experience Headline + Bullet Points are far quicker to convey useful information, in a form that is terse yet easy to read. For example: ---------------- improve Buffer Cache Management & logging - change &#x2

The interesting thing is that DDD identifies & distils most (not all) of the patterns I'd seen used or had to crystallize myself, over the past say 15 years of application development. Key aspects like building a domain (business)

It just moves the problem, to how do you delete the keys & manage backups of the keys. You have to backup the keys, since a system outage would otherwise leave you unable to function. My shot from the hip: encryption/keying is irre

You can run high-volume business and mid-level infrastructure (messaging) systems day-in day-out in Java, and struggle to see more than 0.1% CPU needed for garbage collection. The light-bulb idea here is about reliability, security and prod

I think these insights capture very clearly why "hooks" are a problem rather than a solution. Hooks are the kind of complex technical idea, which some developers (a certain Mr Abramov) find interesting. However "complicated a

Agreed. It's not a "fingerprint" at all as in most cases, it won't be remotely unique. For example: every user in the world with the same screen size, browser & platform will get the same result. For desktop it&#x27

MMP elections, or STV with multi-member districts, result in a broader diversity of parties being elected -- not just two opposing parties. This allows coalitions to form around shared interests, and results in 1) politics being more repres

Good article. Data & state are hugely important for testing, and it's good to see others engaging with the reality of these. I had key responsibility for a very large software system (10M LOC) which was highly configurable; everyth

Interesting. I can't say Lucene gives great results for relevance on a large database, eg. Confluence. However there is a large space between algorithmic assumptions and what "relevance" actually is to the user. This article

Author here. Thanks for reading! As well as these DBs, we also evaluated Kafka and a document database (CouchDB, it seemed awful). For messaging, the Commit Log and Log-Structured Merge Tree storage in Cassandra should have been near ideal.

Exactly. Consistently and reliably storing business data is something that actually turns out to be important in the real world. If you can't actually retain your business data, it really doesn't matter how many "good ideas&q

While I am agnostic as to the advantages of RL over simpler ML, some basic structural concerns seem to apply here. The potential concern is that if RL works, the very best factors for learning are likely to be potentially dangerous. The bes
