If Reddit back in the day had asked a few dollars for me to stick with using 3rd party apps using the API I would have. But they did the opposite, so here I am. First time actually donating to something, a measily $2 dollars a month, but hopefully a start to fund some of the free stuff I use.

I largely agree with this nodding along to many of the pitfalls presented. Except numbers 2s good refactor. I hope I won’t sound too harsh/picky for an example that perhaps skipped renaming for clarity on the other parts, but I wanted to mention it.

While I don’t use javascript and may be missing some of the norms and context of the lanugage, creating lamda functions (i don’t know the js term) and then hardcoding them into a function is barely an improvement. It’s fine because they work well with map and filter, but it didn’t address the vague naming. Renaming is refactoring too!

isAdult is a simple function with a clear name, but formatUser and processUsers are surprisingly vague. formatUser gives only adult FormattedUsers, and that should probably be highlighted in the name of formatUser now that it is a resuable function. To me, it seems ripe for mistaken use given that it is the filter that at a glance handles removing non-adult users before the formatting, while formatUser doesn’t appear to exepct only adult users from it’s naming or even use! Ideally, formatUser should have checked the age on it’s own and set isAdult true/false accordingly, instead of assuming it will be used only on adult Users.

Likewise, the main function is called processUsers but could easily have been something more descriptive like GetAdultFormattedUsers or something similar depending on naming standards in js and the context it is used in. It may make more sense in the actual context, but in the example a FormattedUser doesn’t have to be an adult, so a function processing users should clarify that it only actually creates adult formatted users since there is a case where a FormattedUser is not an adult.

He may have used the wrong word, but maintaining the same function signature across two files (while made easier by IDE tools) sucks ass to do. It was one of the major pain points for me doing a C++ course (along with the abyssmal compilation error messages). Not that I have tried Zig, but I do not see a reason to involve header files in my life if I can avoid it.

Late here, but if you want the easy route then there is always Unity (C#) if it fits for your use case in game dev and the license isn’t a problem for you.

The difference is, with a build pattern you are sure someone set the required field.

For example, actix-web you create a HttpResponse, but you don’t actually have that stuct until you finish the object by setting the body() or by using finish() to have an empty body. Before that point you have a builder.

There is noting enforcing you to set the input_directory now, before trying to use it. Depending on what you need, that is no problem. Likewise, you default the max_depth to a value before a user sets one, also fine in itself. But if the expectation is that the user should always provide their own values, then a .configre(max_depth, path) would make sense to finish of the builder.

It might not matter much here, but if what you need to set was more expensive struts, then defaulting to something might not be a good idea. Or you don’t need to have Option<PathBuf> and check every time you use it, since you know a user provided it. But that is only if it is required.

Lastly, builder make a lot of sense when there is a lot to provide, which would make creating a strict in a single function/line very complicated.

I didn’t really search around for GUIs way back, but ended up making a basic GUI because I wanted to learn programming.

https://camo.githubusercontent.com/5ecb6cdfb3710e359894b65e42b79c7ab7dd8de55a14cdf34f0f0f37d48c7d04/68747470733a2f2f692e696d6775722e636f6d2f346a46776846652e706e67

With just having options as checkboxes for YouTube-dl. It has served me well all these years. It was literally the thing I made while learning programming so the code is pretty janky when I look back at it though…

It’s hyperbole, but I learned my first language because I wanted to be a god.

I saw these magic windows that popped up, that had buttons, and I was jealous of these godly creators holding the power to make them do as they wanted. So, I learned it myself. I peeked at another program I was using, it was using python and PyQt so that’s what I set out with to become my own god of the desktop.

My first program was a GUI wrapper around the YouTube-dl CLI, and I still use it frequently.

I am very content with Riders “hide whitespace and newlines” diff option. Frankly after starting to use auto format on code, all old files that got messy in the diffs next time they were changed.

There’s some other nitpicks that some more aware diff could have but outside python few changes in whitespace matters, so seeing every new line is a waste and visual burden in any review for me.

If CO2 is a byproduct of another process, then I’d make a guess it is fairly cheap. The flaw here is that CO2 and H2 are both products of steam reforming using methane… Which is to say, the cheaper version might just come from using natural gas. Hydrogen has to be sourced from some energy consuming process, and that too is often from the methane steam reformation. So it’s certainly possible, but yet again is ready to become yet another “green” product made from fossil fuel. Doesn’t have to be, but I can be.

Edit: to correct a discrepancy, the article mentioned hydrogen, but if the hydrgon comes from water used in the process then some of the issues of providing H2 is less big. But either way I expect this to be energy costly. Nevertheless, a lab made product is still something that doesn’t need large areas of land to produce.

True, but this is solid state so it may be higher density than current Lithium based batteries. But it might not beat a hypothetical lithium solid state battery. On the other hand, sodium batteries today beat out lithium in many other ways than capacity, and if those things are true for solid state then as long as there is a big enough jump in capacity due to the solid state transition then I think sodium is going to be the go-to for most uses in the future.

Completely true, but also compression can make anything bad. I’ve seen 480p better 1080p simply because the 480p was using more bitrate, where the 1080p is encoded without enough relatively speaking.

I use phone every day at office so I don’t need to get the wallet out of my jacket when going to the canteen to buy lunch. It’s literally the reason I started using my phone to pay. Too many times I forgot my card…

A lot of external drives are just internal devices with another controller and casing around. I had a 4TB I used with my laptop, and tore apart the casing and just plugged it into my desktop when I built one. Unless you start hammering the external case around, the drive will be fine.

The simplicity of Google Photos has me still rolling with that.

But for all my music, syncthing is the best. In my case it’s synced to my phone though, and also backuped up from that to the cloud.

Why wait and hope for C++ to get where modern languages are now? I know there’s value in the shared experience in C++ that if adapted would make it stronger, but I can only see a development of C++ having to force a drop of a lot of outdated stuff to even get started on being more suitable.

But the language is just not comfortable to me. From large amounts of anything creating undefined behavior, the god awful header files which I hate with a passion, tough error messages and such. I also met a fun collision of C++ in Visual Studio and using it with CMake in CLion.

I’ve just started looking at rust for fun, and outside not understanding all the errors messages with the bounded stuff yet, figuring out what type of string I should use or pass, and the slow climb up the skill curve, it’s pretty nice. Installing stuff is as easy as copy pasting the name into the cargo file!

Rust is just the prospective replacement of C++ though, people act like the White house said that C++ should be replaced by rust now. But the just recommend it and other languages, C# will do for a lot of people that does not need the performance and detail that the aforementioned languages target. Python is targeting a whole different use, but often combined with the faster ones.

C++ will live a long time, and if the popularity dies down it will surely be very profitable to be a developer on the critical systems that use it many years from now. I just don’t think an evolution of C++ is going to bring what the world needs, particularly because of the large amount of existing memory related security vulnerabilities. If things were good as they are now, this recommendation would not be made to begin with.

It would kinda go along to “do not go gentle into the good night” like it was presented in Interstellar.

I do think the idea is pretty neat, although it’s pretty close to returning structured data like json.

A slight disclaimer that these people are smarter than me, and know better about what we are talking about, so I may be wrong here on some assumptions. But I do get a bit of feeling they are trying to solve a trivial problem, at least in their use case. Ultimately there are only so many lecturers, and so many man lectures at a given time. The total data amount wouldn’t be so much, and you can easily group by and sort on client side to achieve the original table which is show on a per lecturer basis. A little redundancy is in my opinion preferred over a query that returns 3 tables that then needs additional complicated work. I also find arguments about overlapping names to not be something the database should be handling, it falls on the data owners/manager instead. Academia is a wild west at times, but either this table is presentation only or a link to lecturer or lecture. And in the latter case, you’ll already throw in the ids so they can be used in an URL to some other site.

While this can have significant less bandwidth, it also risks falling as soon as more data is introduced, as you’re putting the large join operations on the client when you can get free optimizations from the SQL engine you use. I know not having duplicate data could be a thing for something where I work, where essentially we have hourly breakdowns but fetch at least the entire day for a single set of parameters. So that means 24x data for a surprisingly high amount of columns. When we only need 2 of them on the hourly level! But in this case, the data doesn’t strictly need many joins as it has a lot of the information itself, along with there being too much data to join on the client side anyways for this to feel ideal. I feel you’ll increase the complexity a bit too much as well. A big advantage of sql is how easy it is to understand what you are getting.

Its somewhat of a solved problem, if the performance becomes a problem, since we can return nested data anyways. So we can already today technically return a row where the hour(I think, never tried a date before) and value columns have arrays instead of a single value. We just haven’t done it because it is not a big enough problem yet.

Completely agree with that, we have the same issue in C# where I work. Just waiting for the day I get to push and update to our shared code style (editorconfig) to force that.

I don’t disagree that this is hard to read, but I feel it’s worth mentioning python has a pretty acceptable style guide. The problem is, it’s far less common in python to bundle parameters into some holding object. So here you have massive function that has to accept a lot all at once. In use it’s probably not as bad looking however.

And at least, it actually explains all the damn parameters. It’s a lot nicer than seeing functions parameters you don’t understand, and all you have is the name. This is not limited to python either
