Only use one notebook at a time. Always write down a date first, on every page if your notes spans to another page. Write down your notes sequentially. Had a diagram in the middle of the page? Continue notes at next page unless you are anno

If we only can have one 20x programmer on the team and the rest, let's say 100 or so, have to be 1x programmer, then absolutely the emphasize should be on 1x programmers. But if it is one 20x programmer on a team of 10, that doesn&#x27

I think you are thinking of "redundant" in terms of information. A syntax does not carry any information on its own. It is a frame for information to reside in.

I think Java Script compiler will assume its guesses for the semicolon cases. Not every one is happy about it.

The compiler "guessed" your errors. This does not mean the compiler "knows" your errors. A rephrase of your question is -- Why compilers don't always assume the "guessed" correction of your code? This is b

I never thought that you are supposed to copy the code from a book blindly. If you do that, there must be some library that you can use that work better. So treating the code as pseudo code, I thought numerical recipes were excellent, bette

Color schemes doesn't work unless we are talking about a dozen standard schemes. Otherwise, it is drowning users in choices. What we needed is an interactive fine tuning. Doing it with config files isn't working. We need a web app

It's not the right abstraction you are making. I assume here we are discussing abstrations above the base programming language level, such as structured vs spaghetti code.

by hzhou321 5y ago
Abstraction is about the core idea without distracting details. Your core idea is likely to either have a finite bound (if the core idea includes bound) or have no bound (if your core idea is just about number). `int32` have the detail of s

> Abstraction in general is usually said to be something which helps readers understand code without delving into the details. I agree with this. And to me, this means a good abstraction is necessary to be ambiguous. For example, number

I guess the word "context" has been misused in computer science. An interface is a computer context. In particular, an interface is full of non-negotiating details. A human context is about why (we need it), what (we want), and ho

What are the key differences between a human audience and a machine interpreter? It is not the language or prose. It is the structure and order. For machines, details comes first. You declare all the actors and types with every non-forgivin

[Disclaimer: I only read the first part.] Let's say we include in the C standard library a routine, `const char *scan_str(int fd)`, one only need to remember to free the returned string once finished with it. Or we can even get away by

The mistake of Knuth is instead of "Literate Programming", he made it, or at least let most people take it, into "Literate + Programming". Depend on which part you focus on, it is either "code" with copious amo

It appears that the mean, the language and tooling, has become everything, and the end, the software or the program or the results, has been reduced to nothing.

For me, the biggest con is the bad code developers commit in order to suppress warnings, both true positives and false positives. The latter really pushes me in the camp of haters firmly. The more warnings you turn on, the more false positi

An ebook device can easily hold many books and makes it equally easy or difficult to switch chapters or switch books. I think that is the very reason I still much much prefer physical books. Picking up a physical book confines me to a set o

No, the compiler or preprocessor should process a higher level instruction that you write using the editor. The editor can run the preprocessor or compiler or a chain of them with single click and load or view any intermediate code with con

Not sure about the example semantics, but with MyDef ( https://github.com/hzhou/MyDef ), it is trivial -- $call value_ops, val, operate, operate subcode: value_ops(v, @ops) type_t $(v) = allocate();

On the other hand, I am also quite annoyed that some projects do yearly major version after 1.0.

Yeah, after 1.x, the 2.0 is one last savior. Beyond that, there is no hope.
