Does anyone know a Java http proxy library, that provides some methods on which I can hook?

CodeX

Would that be considered spam as it points to his github?

Simon André Forsberg

No, it's not spam

Q: jQuery refactoring and DRY principles (basic image slider)

I built a very basic image slider, but I'm still having trouble refactoring. I caught myself reusing same code for clicking the previous/next buttons, selecting a slider dot, and the automated sliding. The difference between these actions is how the index of images changes. I'm not sure how t...

Did my netbeans just go crazy?

BlockingQueue<Message> messages = new ArrayBlockingQueue<>();

it gives errors there

Thanks for clearing that up, i wasn't sure if he was linking for exposure

@ckuhn203 Any time!

Headers in a HTTP request are split by a newline... In the headers the character encoding is written, how do I know what byte represents a newline?

Monking!

Wow this OP is... special.

A: CSV reader and parser

Including the signature, scope opening and closing braces, and all the superfluous vertical whitespace you've got here, the Read method has 223 lines of code, checks if the end was reached in 7 places and includes 4 goto instructions. Other answers already stated it, but I don't think it can eve...

WTFs per minute indeed. OP is trolling hard.

@Malachi This is actually pretty cool. I'm learning all about bitwise comparisons for that Enum.

Malachi

if you want to learn basic Bitwise I would check out the Wikipedia on Bitwise it will tell you the basics on the operations. there are several of them

Simon André Forsberg

@skiwi new lines tend to be byte 10. Sometimes byte 13 + byte 10.

\n vs. \r\n

1:23 PM

Bitwise operation

In digital computer programming, a bitwise operation operates on one or more bit patterns or binary numerals at the level of their individual bits. It is a fast, primitive action directly supported by the processor, and is used to manipulate values for comparisons and calculations. On simple low-cost processors, typically, bitwise operations are substantially faster than division, several times faster than multiplication, and sometimes significantly faster than addition. While modern processors usually perform addition and multiplication just as fast as bitwise operations due to their lo...

hey @Mat'sMug

Q: Java class/method declarations, logical conditions and chained method calls formatting suggestions?

I'm an upstart, been only professionally programming for a bit less than 2 years, mainly in Java as I am currently working as an Android developer. I often find myself thinking about how to improve the readability and maintainability of my code, and establish some style guidelines, for the proje...

skiwi

and a \n and \r\n are the same concept, right?

Simon André Forsberg

@skiwi Yeah, well, byte 10 is always byte 10 as far as I know...

skiwi

1:24 PM

Also...

Simon André Forsberg

@skiwi Yes, both are line breaks. \n for Linux and \r\n for Windows

skiwi

How can I read the character set value if the character set encoding is encoded in that header?

Malachi

there are more than what is listed on that wiki, I don't use them much so I don't know them all offhand, there was someone looking at some encryption code a while back and it had a lot of bit manipulation in it @ckuhn203

Simon André Forsberg

@skiwi Read the header as if it is UTF-8 ?

skiwi

It would be a fair bet

did I miss a fun conversation in Chat?

And, at this point, let me remind people that comments are not the right forum for discussion, please move to chat (The 2nd Monitor) — rolfl ♦ 17 hours ago

ckuhn203

@Malachi Yeah. That what I was using.

Malachi

it's been a while since I tried to dabble with it, when you are working with micro controllers you use them a lot. like arduino

skiwi

@SimonAndréForsberg I'll just ignore all \r's in the header, it shouldn't hurt in theory

Simon André Forsberg

In theory, theory and practice is the same. In practice, they're not.

Vogel612

Shame on you... You wrote my very answer in 3 sentences where I needed almost a full page ;) — Vogel612 1 min ago

Simon André Forsberg

In this case though, I don't think it will hurt in either theory or practice.

Vogel612

Really right the moment I am writing my last sentence that guy shows up and steals the show ;)

ckuhn203

@Mat'sMug I agree with the OP about the Constant name. What if the escape character (for some completely inexplicable reason) needed to be changed to a backslash 5 years from now? Then you'd have to rename it and change all instances of it, or let the name of it lie. Now, I don't think that would really happen for a csv reader, but still...

Vogel612

@ckuhn203 the current name is a PITA though..

ckuhn203

@Vogel612 Not arguing against that fact.

Mat's Mug

1:42 PM

@ckuhn then it shouldn't be a const!

ckuhn203

I'm just saying that "QUOTE" would also be a bad idea for a name.

Because it's really an escape character.

Vogel612

then call it ESCAPECHARACTER

hell, renames are not that hard with IDE's.

skiwi

Yay, I can read my headers!

I don't get this scheme...

GET top-secret-url.com HTTP/1.1

Why is the GET specified before the HTTP/1.1?

@skiwi How much web development have you done? GET for GET, POST for POST...

skiwi

@SimonAndréForsberg How do you mean?

As far as I know, GET and POST are actions possible within the http protocol, why would the used protocol then be defined last?

Simon André Forsberg

@skiwi You mean that it should be "HTTP/1.1 GET top-secret-url.com" instead?

the information is there anyway.

skiwi

I would say yes

Simon André Forsberg

You want to try changing the HTTP protocol specification?

skiwi

That's not really feasible I guess ;-)

Simon André Forsberg

2:07 PM

I'm sure there are bigger or smaller mistakes in all protocols. I believe this one is a very minor one, if they don't have a good reason for why it should be like that.

For me, I think GET xxxx HTTP makes sense.

you can read it like a sentence

GET this page with this protocol

primarily-opinion-based

skiwi

It does make sense like that

What is more clear?

Q: Refactor these two methods

I am trying to refactor two methods. Let me begin with context: I cannot edit the QueryPermissions Class, it is an external dll that was given to me to use. Yes I realize its a bad practice to use an out variables. I am pushing for a rewrite of that service. As you can see below the two metho...

c#

skiwi

if (headers.isEmpty()) {
}

or

if (headers.isEmpty()) {
    ignore();
}

Simon André Forsberg

ignore(); ?

skiwi

Yeah, which does onthing

or a comment?

I think having empty handlers is kind of risky

Simon André Forsberg

2:11 PM

Or you just remove the if-statement entirely?

Or use if (!headers.isEmpty()) ?

skiwi

Maybe this is a case of YAGNI

But it would be nice for future extension to have a hook-in for writing a warning for example

Simon André Forsberg

// do nothing is clearer than ignore(); though.

skiwi

More importantly

When doing the reverse you'll get those huge blocks

Simon André Forsberg

if (headers.isEmpty()) continue; ?

If you want more opinions, you need to provide more code context

skiwi

perhaps

But can't before it's finished :)

Ugly much?

if (!headers.isEmpty()) {
    String[] words = headers.get(0).split(" ");
    RequestType requestType = RequestType.getByName(words[0]);
    String url = words[1];
    RequestProtocol requestProtocol = RequestProtocol.UNDEFINED;

    if (requestType == RequestType.UNDEFINED || requestProtocol == RequestProtocol.UNDEFINED) {
        //ignore
    }
    else {
        switch (requestProtocol) {
            case HTTP_1_1:
                switch (requestType) {
                    case GET:
                        break;

Erm, forgot that big bug there ;)

Do mysqli connections truly close automatically if i dont call $mysqli->close(); ?

Simon André Forsberg

@CodeX I believe they close when your script ends.

@skiwi What are you going to use all this for?

skiwi

@SimonAndréForsberg To rewrite charset=utf-8 to charset=UTF-8 in the Content-Type header

Simon André Forsberg

Oh dear...

skiwi

CodeX

@SimonAndréForsberg i was using $mysqli->close(); at the end of a function then wondering why the next query function wasnt working :/

@SimonAndréForsberg Yep fun fun

This will make for a nice piece of Code Review ;-)

And wow at this

if (headerWords[0].contains(":")) {
    headerMap.put(headerWords[0].replace(":", ""), String.join(" ", Arrays.asList(headerWords).subList(1, headerWords.length)));

Q: Error Handling When Using Dictionary

I have set up a Dictionary that calls on a class to fill a DataGridView via SQL statements. The problem is in two (out of 5) instances the value passed HAS to be an integer. Any idea on how I can add error handling to this? Preferably a message box that just says "value needs to be an integer". ...
