I have this same problem too and what really helps is getting out a pencil and paper and drawing (the minimal) system You'll start out really abstract and with iterative re-drawing you should start to get a feeling of how the boxes should be broken apart into sub-boxes and with experience you should be able to get an idea of how they should be coded. It's not unreasonable to spend several hours doing this until you get your head in the right place imo

jony neuemonic posted:e/n incoming i get this - especially if you're in a larger company where a lot of the work is extension and addition. some tips * think backwards. who's the customer of this? what do they actually want? Once you have an idea of what they want, you can start figuring out how to get them it * Come up with the set of constraints you're working under. Try and really pick the constraints that have to absolutely be fulfilled * Talk to your coworkers about your idea. Rubber ducking helps but getting a fresh pair of brain hemispheres helps more * Be conservative. Assume that your group is going to have to own this, and that every new concept you bring in is yet more cognitive load. The clearest example of this is bringing in a new language that nothing else uses or knows. * Write out a design. Take notes, do some prototyping, come up with your data model and interactions. Write up a design doc that hits these 1. What is this all for? Often times you know how exactly what you mean when you say "Frothing Bit Reaper" but unsuprisingly a lot of your peers won't. Explaining what this is and why we're doing this is important for context 2. Remember those constraints from that other bullet? Add these in too. Without those, someone reading your doc will think you're making the wrong decision because they lack the context of the constraints you're operating under. 3. Go into medium-level detail. Be specific enough that you could hand the doc off to someone else to code it up, but general enough that you haven't literally done all the work It turns out that "measure twice, cut once" is very applicable to software development, and having a document on hand that explains the what, why, and how of the project is really helpful for the actual implementation of said project

I doubt even post-c++03 could help you in any way

if dynamic cast would be optimal but it isn't efficient enough you can very easily hack up your own dynamic cast based on either virtual calls or (probably better) information you store in the base class. if your boss is dead-set against templates, well, be thankful that you only have four cases to support. something likeC++ code:this is basically what we do pervasively in llvm/clang/swift where we care a lot about casting and generally don't want to pay for v-tables

Serendipity has made it official. I'm done with my task at hand I've been working on refactoring the build system at work. It was pretty poo poo a few weeks ago - coders had to `make clean` before every build. Gradually I improved it, and a few days ago I thought it done, but not feeling satisfied I pressed on, inventing and testing new ways of improving the system. Things that nobody will probably ever use or appreciate, but damnit those things mattered, because the less you have to gently caress with Makefiles the better. Thus I toiled throughout the nights and weekend days, determined to leave the system at nothing less than optimal. Well just a few mere minutes ago I believe I reached that point was nothing could be thought of to to add or remove. Now I usually like to let my playlist run on shuffle while I work. As I made my final mass sed replacement, a soothing crescendo of synthetic horns - unrecognized to me but nonetheless pleasant - made its way through my speakers. A few moments of reviewing the effects of the sed command, I was ready to test those final changes. No sooner had I entered 'bash test_make_all.sh' into my shell and the familiar spewing of the compiler commands begun scrolling through the console than those soothing horns led into - I poo poo you not - the unmistakable opening chords from the loving theme of loving chariots of fire.. So I watched in awe as over 20 different `make -j sometarget &` processes simultaneously spewed their outputs to the console and wept a tear of joy and danced a giddy dance as serendipity of the moment overwhelmed my soul with the purest joy. Gentlemen, I'm done.

Still undecided on typescript vs flow for this reactjs side-project. I rather wish this rift didn't exist tbh Flow: - Written by a bunch of guys who love javascript so much they wrote a type checker for it in ocaml. - poo poo performance under windows. Supposedly. - The main IDE is Atom. What the gently caress even is Atom. How do I do anything beyond notepad.exe's capabilities with this goddamn bullshit. - Yeah you can kind of use it from VSCode but the integration is third-party and really crappy and you have to rip out half of VSCode to make it work so wtf is the point. - I erroneously wrote "import type * as types from 'whatever'" and this sent it into a crash loop. One crash loop per CPU core, as a matter of fact. - There are already two incompatible versions in wide use. - Facebook's whole dev tooling landscape in general is really vertically integrated and keeps wanting to drag in other poo poo of theirs. + Works with create-react-app out of the box (misnomer: this is a canned build system for react projects with sane defaults). + Facebook is stuck with this poo poo so they have to keep React and Immutable and all their other crap sort-of working with it. + Supposedly a stronger type system, and was in fact developed in response to perceived weaknesses in the design and objectives of TS. TypeScript: - Not a first-party solution: poo poo will break and I have to hope that people will be entertained by the process of fixing it. - Don't know the details but the type system has impedance mismatches with Redux and Immutable.js. See above. - Supposedly has a weaker type system than Flow. + I can edit it from VSCode and VSCode doesn't make me want to punch somebody + Has first-party support from redux-saga. + Has wider first-party support in general. Like there's a Protobuf library that emits TypeScript stubs, no such luck for Flow. Honestly my main problem with Flow is that I really hate Atom from what little I've seen of it.

imo i'd go with typescript unless type system impedance mismatches are going to wreck the ball hard or you really can't get flow in something adequate (say, webstorm)

Notorious b.s.d. posted:how long is it gonna take y'all to learn emacs is the one true path elisp is poo poo and vimscript is double dog hypershit. atom is unironically a potentially better editor than both emacs and vim because it's built on top of javascript. yes, javascript is bad, but enough developers are stuck in this loveless marriage that the developer community is forced to somehow make javascript itself work. modern editors are a text entry widget bolted on to a programming language, in much the same way that an A10 is an enormous gun that somebody mounted a plane onto. the choice of underlying language is crucial.

if you are writing so much javascript that you need typescript to fix it, you're writing too much javascript. your javascript should really end at form validation and even that should just be the one line that adds the unobtrusive validator.
