RELOAD!

Phrancis

I'm getting POST from this radio button:

  <input type="radio" checked="checked" name="timeInterval[]" value="travelDays" />Days
  <input type="radio" name="timeInterval[]" value="travelHours" /> Hours

When I echo it, all it prints is "Array" what am I doing wrong?

RubberDuck

@konijn thanks for the compliment earlier. It's nice to hear good things about your code now and then.

@mjolka I'm just going to pretend I didn't see that... Yup. Nothing to see here. Move along.

mjolka

@Phrancis try print_r instead of echo?

1510:         for (;;)
1511:           {
1512:         int digit = MPN.divmod_1(work, work, len, radix);
1513:         buffer.append(Character.forDigit(digit, radix));
1514:         while (len > 0 && work[len-1] == 0) len--;
1515:         if (len == 0)
1516:           break;
1517:           }

@RubberDuck just for you

Phrancis

So then it printed Array ( [0] => travelBack ) is there a way to make it print/echo just travelBack that you know of?

mjolka

@Phrancis i'm not seeing the difference

Has anyone present used the Brackets web coding software?

TheFailure

Me

Phrancis

It may be an issue with the code; it works on phpfiddle but not in Brackets. I have a HTML form with an action directing to a PHP file. I fill out the form and click the Submit button, which is supposed to call the PHP file. But when I do in Brackets it says it "Cannot POST" the PHP file

I read this on SO:

> Make sure you don't have any kind of redirects, since you're using index.php to save data, you're probably reloading the page to show the updated comments. And if you're reloading, there'll be no data on $_POST to be printed

But have no idea why it would work one place and not the other

Could this have anything to do with it?

mjolka

TheFailure

How good is JDOM and why should I use it ;)

mjolka

not sure why you're not getting votes on it

rolfl

@TheFailure Good question, first ask yourself, do you need to use XML....

TheFailure

02:53

@rolfl Actually I do have something I want to use it for

rolfl

If you need to use XML (and Java), and the documents are relatively small (a few meg or less), then you will likely be better off with JDOM than any other in-memory model.

If you want blazing performance, then you want to use SAX, and not DOM

but at the cost of some pretty complicated code

TheFailure

@rolfl So a few meg max?

rolfl

At some point you should use regular DOM just to understand why JDOM is so much better

JDOM is better than DOM when it comes to memory, but, none of the in-memory XML models are really worth it when you get to large documents.... where 'large' is about 10% of your system memory in the raw form.

TheFailure

Okay

Thanks :)

rolfl

With XML there's two basic systems, streaming, or in-memory

either you process the data as it flies past, or you load it all up, and have 'random access' to it.

the 'random access' system is really intuitive, and easy, but you need to have it all in memory

TheFailure

02:57

I will be using in memory

rolfl

XOM, DOM, JDOM, and others all load the whole thing in to an object-oriented tree structure in memory.

SAX lets you watch the data stream past, and you pull out what you want as it flies by.

If you go with the *OM models, they all have the problem that you have latency restrictions (you have to process the whole XML stream before you can access any of the data), and you are limited by memory too.

So, if you are going the *OM route, your choices are DOM, which is good if you don't want to use external libraries (it is built in to the JVM). JDOM is good because I say it is, and XOM is the other common contender, which has a different philosophy.

Phrancis

> JDOM is good because I say it is - rolfl

rolfl

DOM is in wide-spread use, but the problem is that it is a model designed for all languages (C, C++, Java, etc.) which also means it is designed for NO languages.

It has the same interface regardless of what language you use, and it is the lowest-common-denominator of all.

That's nice in a sense that if you change languages and so on, the XML API stays the same.

Unfortunately, it means in Java you can't use iterators, lists, sets, etc. in the places where it would be 'logical'.

JDOM fixes that aspect.

JDOM is all about doing things the Java way...

TheFailure

Sounds great

rolfl

Of course it does ;-)

Have a look at: studytrails.com/java/xml/jdom2/java-xml-jdom2-introduction.jsp

TheFailure

03:05

Not bias in any way?

rolfl

I wrote or rewrote JDOM 2.x, not biased at all.

OK, just checking. Yes, I am biased

TheFailure

If something doesn't work I know who to come after ;)

Jamal

Thanks, Santa!

rolfl

03:24

@Mat'sMug It's not whether the pivot is faster or not, but the fact that there's no # table, and that the pivot is processing all the data, whereas I am just 'pivoting' one value per date.

@Jamal Wasn't me ... should it have been?

This is why C is complicated:

> You have both <cmath> and <math.h>, but you only need the former. The latter is a C library.

So, cmath is not the C math library, but math is.

Jamal

Only math.h will work in C, while both will work in C++. It's not a super bad thing to use math.h in C++, but I believe it will import some unnecessary things, plus it's not under the std namespace.

Hey @janos

It just made sense to check for a negative condition, when expecting otherwise, at first, if just for readability... Never knew what ! operator was for until you mentioned it

Of course, my dumb ass would never have figured that out, having used != operator I never made the link :)

janos

it exists in most languages. It's a big surprise that in Python it doesn't, there you have to spell out not

Phrancis

In SQL it doesn't either, or at least it's been deprecated

Always found the <> operator instead of != kind of odd.
