At a high level, there are some things that coordinate when transactions happen in terms of WAL logging: 1. The Buffer Pool (memory for pages in the database) 2. The Log Manager 3. The Transaction Manager 4. The Storage Manager (read/w

Ah I hadn't considered it would be too large to be held like that, thanks for the heads up

I didn't know something like this existed, thanks for a thorough review I want something like this for reading PDFs (in tablet mode) and possibly coding from my phone, that I can carry around in my backpack when I'd rather not bri

Ohhh, fair enough, yeah I see what you're saying. Yeah you're boned in that case I think and that's a real problem that can pop up if you want full @nogc EDIT: Maybe not based on Max's comment D-Plug (Audio FX plugins) i

I like choosenim because it can build and install nim nightlies and master which for most distros aren't available in repos

Aye, you can turn off GC entirely, for the whole program There's even a mode of D that operates this way by default, "-betterC" meant to be a C replacement The GC really is an entirety opt-in component. I'd encourage you

I'm not sure I follow Is this about D code that interops with C/C++? You have "extern (C++)" and @nogc for that

It was a small personal project, I posted about it here some months ago fwiw: https://news.ycombinator.com/item?id=34211482 D has no (FAANG) corporate sponsor and it does all things well/has no particular speciality, t

D is the systems language I enjoy writing the most out of C++, Rust, and Go. It feels a lot like a mix between C# and JS, but at the low level access of C++. It has a lot of unique features but the "killer feature" by far for me i

I don't know anything about this domain but I wholeheartedly believe consciousness to be an emergent phenomena that arises in what we may as well call "spontaneously" out of other non-conscious phenomena. If you apply this ru

Some of it is nogc compatible, some of it isn't All functions in the stdlib that are nogc are marked "nogc" in their definition

The garbage collection is an optional feature you can disable though There's a lot of "@nogc" D code out there. Audio FX plugins that do realtime DSP and game/graphics stuff come to mind. I'd rather have the languag

Thank you for the work on KoWasm It's been exciting to watch the development of the new K2 compiler and Frontend-IR format Kotlin is no longer just a JVM language, but more like a frontend with targets that now span everything from JVM

Could I suggest adding a "Motivation" section to the README? It made sense after reading the comment about not needing a C toolchain for cross-compiling CGO but I didn't realize it immediately. Neat stuff

Not the poster but the hunger lessens after the first few weeks as you adapt to it, or at least that's my experience I start to dread eating a bit now because I get tired/sleepy after I do. I want to eat because I'm hungry bu

Huh thanks for the explanation, I've always wondered how that worked.

It gets hairier than this. For example, in Postgres, the place where all the metadata is stored that the DB uses in internal business logic is not regular C structs, but as rows in special tables (relations). Like say you want to look up th

I just want to say thank-you to the folks who work on Code Search at GitHub. It's the number one way I research and understand new libraries/API's and programming languages. There's a lot more you can learn from usage in

I also moved from a decade of Ubuntu to Fedora over a year ago Was a fantastic decision, I think the project is run much better and the pace of development and innovation for software devs specifically is much better.

The article seems to contradict itself: The first example shows the server rendering a handlebars template and then sending that as a response to the client -- it's then stated that this "isn't true SSR" Then the same th

I'm currently writing my own database from scratch and at the point where I have a buffer pool and storage layers, and can do scans with these (no actual query layer obviously, these are raw heap-file scans) I'm now studying, tryi
