CMQ: If I'm inserting a user-entered value in some HTML like <h1>____</h1>, are angle brackets the only characters I need to ban to prevent HTML injection, or are there other characters I should ban too?

emanresu A

Why not use innerText?

DLosc

I'm using JSP

<h1><%=applicationName%></h1>

emanresu A

<>&

DLosc

I suppose I could use the JSP to generate some JavaScript that uses innerText...

& is a bit bothersome because I could see someone wanting to put an ampersand in the application name. Maybe instead of banning it, I'll replace & with and. :P

emanresu A

Just replace them with html entities - < > &

DLosc

Oh, fair

@DLosc oof

Imagine not using a framework like STRUTS2 :p

@lyxal No, you're confused. "Bean rather fun" describes the card game Bohnanza. ;)

You clearly aren't using POJOs with your JSPs :p

@lyxal I am certainly not using Pulpy Orange Juice Omelets with my JSPs :p

Because using Java for your web backend is a good idea

And something I had to do for a whole semester

I made a message forum, number guessing game and it support ticket system using Java for the web :p

DLosc

Most of the time, I don't write the JSP or Java code myself, our development system generates it. So I don't actually know very much at all about Java Web development.

@lyxal It runs on Apache Tomcat, if that's what you're asking

lyxal

That is

user

01:41

@DLosc may i ask what you use to generate it?

Do you write templates with an occasional snippet of java code in them?

Or is it generated by a dsl in Python or something?

Or a graphical application without any code?

Radvylf Programs

04:39

@DLosc FWIW OWASP recommends replacing every non-alphanumeric character with its decimal ampersand code

It's way overkill, but pretty easy to implement and almost guaranteed to be secure, even if you decide to move the generated text to an attribute or even a non-quoted attribute of an element

It's also really simple to do, usually less code than doing it the traditional way (< -> <, > -> >, & -> &, and " -> " and ' -> ' if it's a quoted attribute)

mousetail

Infinity?

Would chain the best if recusive

Adám

@Neil ~~can~~ cannot?

Neil

@Adám well, its LDW, so I get to ask you to help me decide whether my recent change to Charcoal that makes Minimum([]) crash instead of returning None was a bad move

Adám

Well, it should give ∞ or maxnum.

Minimum is just just a hidden reduction, so you need the identity element of minimum, i.e. i such that min(i,x) = x for all x.

Neil

yeah, except I don't know the type of an empty list

Adám

12:00

Type?

Unrelated String

you could have a value that compares greater than both all numbers and all strings or whatever the other type is

Neil

the other type is lists, good luck finding a maximum of that

Unrelated String

an infinite list all of the elements of which are itself :P

but what i meant is just having a magical value that's neither/both types

though come to think of it, in the case of the maximum of an empty list, an ordinary empty list would fit the bill if we ignored numbers

mousetail

How do lists and numbers compare?

Lisp (programming language)

Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1960, Lisp is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket and Clojure.Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of...

@user Inform 7's rulebook system where you can conditionally override a method.

user

Whoa, how does that work?

mousetail

You can write something like "Instead of doing X if Y, do Z" and if you call X and Y holds you can do Z instead

I imagine it's useful for validation and authentication stuff in a more practical language

Like "Instead of loading the admin page when not a admin, show a permission denied error" then you don't need a lot of authentication and validation logic inside the admin render function at all

Ginger

wow

user

So you have to show that Y holds at compiletime?

mousetail

No, it's evaluated at runtime

Inform 7 doesn't really have classes so Y can depend on the arguments but also on global state

user

15:10

Interesting

mousetail

Oh and there is also a type of cancel command you can do inside Z that you can use to conditionally cancel the override and run the original behavior of the function anyway

I imagine the world's coding has ground to a halt now chatgpt is overloaded

@Simd RIP coding

@UndoneStudios maybe the machines will find it more efficient if they ask us to do some parts for them

UndoneStudios

@Simd at the cost of nature

Simd

I am trying to optimize a function. If x is the previous value, t2 is the gradient at x (between 0 and 1) and t1 is the new value after one iteration of the optimizer, how should I interpret (t1 - x*t2)/(1-t2) ?

apparently this is the next value for x

but I am not sure why

UndoneStudios

Note that if t2 is 1 you will start a black hole

just kidding

zero-divisions

@Simd What do you want exactly?

Anyways, here's my code currently: main(){char s[10];for(i=0;i<11;scanf("%s",s[i++]);)}

Next step is to delete the subjects not neccessary

That would require some constraints

mousetail

15:53

You are still trying to write a string in a space only big enough for a char

UndoneStudios

@mousetail ?

mousetail

char s[10] creates 10 chars

Then you try to write a string in each char

UndoneStudios

@mousetail Oops, how do I create an array of strings?

mousetail

char s[100][10] to create strings of 100 characters

UndoneStudios

Oh okay

Added 5 bytes but nevermind

Hold on a second, do you also know how to program in C?

mousetail

16:02

C is like the easiest language, as long as you don't touch strings

UndoneStudios

I didn't ask that

> Hold on a second, do you also know how to program in C?

mousetail

In that case No, I only use it for golfing but struggle to understand any complex C code

UndoneStudios

@mousetail Same

I'm learning C ~~to reduce my dependance on Python~~

mousetail

Rust is basically better in every way

C is a good language to learn though

since basically every other language is based on it

UndoneStudios

Also another reason I'm learning it

Without C, I don't know what I'd be doing right now

other than simply walking around and wasting time

K gtg

mousetail

16:09

@UndoneStudios BTW in real C you would write scanf("%99s") to prevent buffer overflow. It's not really necessary when golfing but your application can easily be hacked if you don't limit the scanned string length.

Ginger

16:47

ok so here's an idea: A tool that lets you easily distribute Python applications by letting you both bundle them into wheel-like distributable files and install them into virtualenvs
