Q: HTML code runner/tester?

YouCan'tHrefMeIs there any HTML Code runner or tester available out there online? I would like to practice HTML not only in my Phone but also in the Computer. Can anyone help me out?

 
12:40 PM
Thanks for providing more info. In general, stackoverflow is here to answer specific questions more of the "why does this code error out?" or "Why is my view always black even though I'm...." variety than questions about approach or code review. I think you are asking for help with handing the XML data that was sent to you, but you haven't supplied that code. Saying this is not very helpful to you, so I'm going to post an "answer" that can continue the dialog outside of comments. — tobinjim 32 secs ago

@RubberDuck Depends on your usecase
Should people be able to add to it or only iterate it? Do you want to use iterator blocks? Do you want to propagate lazy loading?
Will you be working with arrays or just any collection type?
 
All very good questions to ask. Thanks you.
Although, I'd say asking the last one breaks the abstraction.
 
Meh, it's a question that should be asked with regards to performance
If you know beforehand that you'll have heavy usage of arrays in that code then returning an IList<T> means that every array will have to be turned into a list
 
Perhaps.
Either way. Thanks @JeroenVannevel.

@JeroenVannevel the entire project. if they can't figure out the HTML, they shouldn't be looking at my code in the first place, right?
 
2:13 PM
I'm a bit confused about what you are talking about
 
like full Documentation of my project. I hate even thinking about it, doesn't feel as rewarding as actually writing the code... but I know that it must be done, and now I have this project and about 4 others that I need to document as well.
I guess it would be Technical documentation.

@Mat'sMug (The Original Mug) I am looking at your code and about to post something that I am unsure of.....
 
Sam Brand on April 07, 2015

Every year we ask our users to tell us a little about themselves. This year we asked our users to tell us a lot.

For 2 weeks in February 2015, we ran a 45 question survey. We asked where you live, what programming languages & frameworks you use, how much money you make, how much coffee you drink, and whether you prefer tabs or spaces when writing code. More than 26,000 of you responded, making this year’s survey quite possibly the most authoritative developer survey ever conducted.

A few findings: …

 
   return context != null && ((context.CALL()) != null && (context.CALL()).Symbol.Text == Tokens.Call);
is it ugly or clear?
 
You're executing context.CALL() twice
 
I agree. will you check my answer. I explained why I left it like this
	private bool HasExplicitCallStatement(VBAParser.ECS_MemberProcedureCallContext context)
    {
        var statement = (context.CALL());
        return context != null && (statement != null && statement.Symbol.Text == Tokens.Call);
    }
 
2:26 PM
More male students prostitute themselves than female students to earn some money
I could do that..
@Lyle'sMug Now you're executing it three times!

@Lyle'sMug nope

A: Here's my interface, so call me ...maybe

Lyle's MugI am thinking that you could shorten up your private boolean methods a little bit by including the early return into the return conditional, so you would take this private bool HasExplicitCallStatement(VBAParser.ECS_MemberProcedureCallContext context) { if (context == null) { re...

 
The first part of your return can never be false
context will always be not null
if it was null, it would've thrown a NullReferenceException before that
when you call context.Call()
 
@JeroenVannevel Uh wow, that's quite desperate
 
So that has to be at the top anyway -- it's parameter validation
 
@JeroenVannevel then his code is wrong to begin with, as it will always return false.
 
@Lyle'sMug I don't see why it would always return false
 
2:30 PM
> Your Stack Overflow rep is a strong indicator of how much money you make.
Oh oooh
 
context can be null or not be
 
if the first condition is false I want it to return false, if there is a context, then I want the other conditions to be validated
 
in your case it will throw an exception if it's null instead of returning false
var statement = context.CALL();
It will never reach the return statement if it's false
^ this line throws an exception before that
 
why can't a var be assigned a null,value? it is weakly typed if context.CALL() is null then statement will be null
 
> 26,086 people from 157 countries participated in our 45-question survey. 6,800 identified as full-stack developers, 1,900 as mobile developers, 1,200 as front-end developers, 2 as farmers, and 12,000 as something else.
 
2:32 PM
@Lyle'sMug Let's walk through this line by line
Given this code:
private bool HasExplicitCallStatement(VBAParser.ECS_MemberProcedureCallContext context)
{
    if (context == null)
    {
        return false;
    }
    var statement = context.CALL();
    return statement != null && statement.Symbol.Text == Tokens.Call;
}
 
I am going to see if I can run the code and test it
 
If context is null, the method will return false. Agree?
However when you look at your code:
private bool HasExplicitCallStatement(VBAParser.ECS_MemberProcedureCallContext context)
{
    var statement = context.CALL();
    return context != null && (statement != null && statement.Symbol.Text == Tokens.Call);
}
If context is null, it will execute context.CALL() anyway
Resulting in a NullReferenceException
You can't call a method on a null reference
So your method immediately crashes
This also makes the following context != null statement useless, since it can never reach that code anyway if context == null

@JeroenVannevel this makes sense
 
@SimonAndréForsberg Yes, now that the stupid basketball .... crud ... is over, we can get back to the regular CBS lineup.
 
2:40 PM
I guess the next question is can I reorder this: ((context.CALL()) != null && (context.CALL()).Symbol.Text == Tokens.Call)
lol jk
 
> Source control is an industry standard tool. However, fun fact: about 10% of developers still don't use it.

I prefer a tab the size of 4 spaces.

@JeroenVannevel stargreed
 
It's wonderful how in hindsight my day seems totally wasted when I game instead of study compared to when I program instead of study, while in both cases I'm not doing what I'm supposed to be doing

2:49 PM
@skiwi That's my daily feeling exactly
I try to offset it by applying for a company or two and reading a blogpost each day
 
Well, but your study is going succesfull, no?
 
Depends how you look at it
I typically look at it from the most glamourous side
 
@JeroenVannevel That's a shady statement
 
@rolfl Would you believe me if I told you that UScale determines the OP's original highest pit method to actually be O(n) ?
 
Yeah... I sort of would.
 
2:51 PM
I edited my answer to show that
 
Well, I'll have done my studies in 5 years instead of 3. But that is very common in Belgium. And I'll be finished in December 2015 so I'm almost finished
 
I think I should also do some real benchmarking here
 
Would you believe if your own program told you you were wrong?
@JeroenVannevel I see, also a 3 year study here... currently finishing Y4 Q3, estimated to finish halfway 5th year, realistically it might take the full 5 years
 
Bad students unite!
Good thing we don't have American college tuitions
 
Ummm...... no. No I'm not going to turn off an error report just because you asked me to...
 
2:54 PM
Yeah... luckily
 
@Simon - consider this:
    for(int j = pos; j < A.length; j++) {
        if(less) {
            if(value > A[j] && A[j] != value) {
                q = A[j];
                if(j+1 < A.length) {
                    r = calcPit(A, j, value, false);
                    int tmpResult = Math.abs(Math.min(value-q, r-q));
                    return tmpResult;
                } else {
                    return -1;
                }
            }
        } else {
            if(value < A[j] && value != A[j]) {
                return A[j];
if(value < A[j] && value != A[j]) {

@skiwi My parents forced me to pay my tuition 2 years ago because I had less than 50% at the end of the year
It's a bitter pill but only 600€ in the end
That's a week and a half of student work in the summer
 
@JeroenVannevel The government here covers nominal + 1, so that's 4 years
 
2:56 PM
@rolfl Agreed. It's very hard to follow what is actually happening...
 
I'm actually more or less getting paid to study right now
My problem is that I'm not really studying, it's hard to concentrate on it
 
@SimonAndréForsberg The reason it probably comes up as O(n) is because the recursion depth is dependent on the distance to the next peak, not the size of the input array.
 
@skiwi Yeah I feel you. That's why I tend to pass for half of my classes each year
This year has been particularly good though! 6 out of 8 passed in the first semester
That's unseen
 
My first year was exceptionally good, then it got worse
 
@skiwi and @JeroenVannevel I don't think it has to do with being a bad student in a majority of cases, a lot of people need to work while they go to school these days, which means they would need to take less classes at a time in order to give each class the amount of study time required to perform well.
 
3:00 PM
Except... I'm not working
 
Yeah, me neither
 
lucky so and so's
 
Though I've been having a side-job for 1,5 years and in hindsight I think it has actually impacted my study
 
@skiwi which way?
 
@Lyle'sMug Working less on study, but it may just have been 1 hour max I would've spent during that workday
 
3:01 PM
I see.
having a family impacts study time as well.
having a girlfriend/wife actually.
 
There are people that can use almost all of their free time to study, and there are those who cannot
When programming I often feel like I'm learning more than when studying even
 
I've passed all but one programming-related course. The only ones I have left are economics and math classes. It's particularly hard to motivate yourself for some stupid bookkeeping stuff when you have all the knowledge needed to start working

I can't get myself to study hard for Artificial Intelligence right now, I mean it's all cool and interesting for sure, but the exam consists mainly of meth math

@rolfl yes, that makes sense. I think there is a worst-case scenario in which his code would be more O(n^2)

@SimonAndréForsberg That whole thing has p'd me off.

then the next answer came in with the O(n) solution, but it's a messy solution, and is not a review.

Over the weekend, I found a new algorithm to add two Gray codes. It's currently slower than the previous one I tried to optimize which in turn was already slower than a naive solution.
Way to go /o/
 
@rolfl yup, I've seen it. I didn't quite understand what you were doing, the point of the inflection variable especially confused me. It seems like I didn't miss much though as it doesn't produce correct results.
 
Correct... it measures the pit relative to the highest neighbouring peak, not the lowest peak.
So, all I had to do was measure between one peak and the next pit (or between one pit and the next peak.)
So, all I had to do was record the location of the previous point of inflection, and take the max of the altitude difference.
 
So, all you had to do was to read the description and understand it correctly.

When you get this all working correctly, I'd strongly suggest posting it to CodeReview.SE so that people can work help point out these small things that aren't that small and you can understand all the minor gotchas and ways to implement what you are working on better. — MichaelT 1 min ago

Hmm, I prefer spaces, but prefer pressing tab. Also, I like backspace to clear a tab's worth of spaces at a time.
I like Xcode.
Also, I am slightly below average age for my country.

I can't believe you'd compare this to the ease of #import statements! :) ...that said, this is an extremely helpful guide, and it does look like this is the best we're going to get. Practically, it means that I'm going to write everything first and then chop it up into modules near the end of the project, which isn't that bad a way of doing things. Thank you very much, this will be really helpful. — Le Mot Juiced 2 mins ago

You might want to consider code review for this kind of question. — RubberDuck 1 min ago
 
That is a keen observation, @SimonAndréForsberg. You're probably mistaken on a couple of things though (as well as me). As I look at it, I can't actually say for sure that the lookup table is faster. We're talking about 256 or so bytes in memory that will be cached very close to the core (L1 cache), but, 4 if/else statements may be faster than 1 L1 lookup. It's a margin call. I would guess that all the systems (if/else, 4-value table, and all-value table) will be about as fast as each other in this situation.... Code Readability is probably the important thing, and I am not sure mine is best. — rolfl ♦ 55 secs ago
@Simon - it will likely require a benchmark to prove which system is fastest.

Q: Expected value (and distribution) of sum of six balls labeled 1-49, no replacement

ADGThis code finds expectation and standard deviation of sum(x) of 6 digited base-49 numbers with all digits distinct. The expectation is sum(y) of sums(x) upon the total no of sums(x),i.e. e=(x_1+x_2+..x_n)/n whereas standard deviation is squareroot of sum of squares of sums(x) minus the expec...

Please format your code so it is easy to read. That wouldn't only be helpful for us to help you but also for you to find those kind of errors easily. The checkbox construct especially is something I, as a code reviewer, would just throw in the bin. — b.enoit.be 7 secs ago

@RubberDuck i develop VBA myself, and my comment was not supposed to transfer any negative message towards VBA development. I was just pointing out, that there is no error in the code, and that it is better placed in code review as you mentioned, because here i would expect more questions where things are not working at all or have errors. So from that perspective the code is fine and it surely can be optimized - but not here :) — hexerei software 18 secs ago
 
@Simon, do you understand this comment?
The sequences must be strictly monotonic and you return "Deepest pit in [7, 3, 3, 1, 7] is 6" (instead of 2). — maaartinus 21 mins ago
 
@rolfl strictly monotonic??
 
Nevermind.... I do understand it now.
mutter grumble, that questio n has been nothing but trouble for me
 
@rolfl Another test failure?
I agree that [7, 3, 3, 1, 7] should return 6
 
Nahh..... the actual question is:
sequence [A[P], A[P+1], ..., A[Q]] is strictly decreasing, i.e. A[P] > A[P+1] > ... > A[Q];
Note,> and not >=

IMO, it would even deserve its own close reason in a way, but it is suggested that "unclear what you are asking" should be used instead.
