@Yuushi Probably best if you had some kind of symbolic processor that didn't evaluate until everything was reduced to simplest terms.

When you get into the nitty-gritty of SQL (stuff more advanced than select-insert-update-delete) I think it compares to programming to an extent, although very much domain-specific

@Phrancis funny. I wrote some T-SQL yesterday to infer the sequence of "production scan sites" in a db table that had "next site" for each scan site record. Used while loops and all. Felt like programming. And felt like wrong SQL, too.

hmm... nitty-gritty fast SQL is very often more complex than the everyday programming...

Rubies are such pretty stones.

@QPaysTaxes I know I suck at this too, but... critizise the code, not the OP..

7:03 PM

@Mat'sMug Well, sometimes even in SQL you have to use loops, some things just can't be done set-based

@Phrancis Does that count?

@Phrancis if it was more than the 30-some records in that table I think I would have written in in C#

/**
* @author Francis V.G.
* Policy term expiration calculator
* Business rules dictate that the expiration of a fixed-term warranty policy
* is calculated by multiplying 365 by the term, hence coverage than spans
* leap-years will have a few days difference between start and expiration dates.
*/
DECLARE @YearDays INT = 365;
DECLARE @TermInYears INT = 10;
DECLARE @Term INT = (@YearDays * @TermInYears);
SELECT
    [Current] = DATEADD(DAY, @Term, '6/16/2015')
  , [Correct] = DATEADD(DAY, @Term, '6/12/2015');

How I write SQL ^^ ;)

@Mat'sMug Does C# loop over DB records much faster than a DBMS?

Yes.

That's my plan.

Q: Is my implementation of removing an element and the one following dangerous?

I have an ArrayList of Strings. I want to delete all elements with a particular value and the element immediately after that one. I have an ArrayList with the elements "Ape", "Bear", "Cat", "Dog", "Emu", "Fox", and "Gopher". Any time I see "Cat", I want to delete "Cat" and the element immediat...

@QPaysTaxes Go Mr. Taxes, go.

Q is a fictional character in the James Bond films and film novelizations. Q (standing for Quartermaster), like M, is a job title rather than a name. He is the head of Q Branch (or later Q Division), the fictional research and development division of the British Secret Service. Q has appeared in 20 of 23 Eon Bond films; all except Live and Let Die, Casino Royale and Quantum of Solace. The character was also featured in the non-Eon Bond films Casino Royale (1967) and Never Say Never Again. == NovelsEdit == The character Q never appears in Ian Fleming's novels, only the Q Branch is mentione...

@QPaysTaxes Whenever someone mentions the IRS, I can't help but think of the movie Stranger Than Fiction.

Stranger than Fiction (2006 film)

Stranger than Fiction is a 2006 American comedy-drama-fantasy film directed by Marc Forster, written by Zach Helm, and starring Will Ferrell, Maggie Gyllenhaal, Dustin Hoffman, Queen Latifah, and Emma Thompson. The main plot follows Harold Crick (portrayed by Ferrell), a nondescript white-collar worker who begins hearing a disembodied voice narrating his life as it happens – seemingly the text of a novel in which it is stated that he will soon die – and he frantically seeks to somehow prevent that ending. The film was shot on location in Chicago, and has been praised for its innovative, intelligent...

Hmm. My employer has five credits in the IMDB.

@QPaysTaxes it's probably close enough..

Hmm. Apparently it's more like 25 under different variations:

Q: Parallel factorial algorithm using std::thread

This code calculates the factorial of a number on multiple threads. My issue: it is only a little bit faster than the sequential version of it (and I think I know why, I just can't find a way to solve this).

@QPaysTaxes The nested fors are surely no good idea. You you surely haven't seen my variables, unless you hacked my computer.

@Vogel612 No idea. You'll have to ping him.

@rolfl quick question about XPath (or rather XPathFactory) ...

is there a way other than giving a Filter to get an Expression that doesn't have Object as T?

8:10 PM

My point is that I haven't posted my solution yet.;) And I'm not sure if I will as all these optimized stuff is fun to write but hard to read. And nobody cares.

@QPaysTaxes But you know, Lombok. :D

D:D:D Actually, not this time. Simply because there's not even a stupid getter there.

But I'm working on another solver.

okay nevermind, I found the Filters class..

Neither nor. Just indifferent laughing.

8:30 PM

Should I add a downvote?

Assuming you mean your last question, I can't do anything with it as I'm too ignorant with Ruby. I hate weakly typed languages. :(

All I can say is that people indenting with spaces rather than tabs are strange.

strongly disagree

Hi @QPaysTaxes.

hey @QPaysTaxes

@janos I was expecting this. It's insane, but insanity rules. ;)

8:46 PM

yeah, I had the feeling you might be simply bored, and just made an inflammatory remark to spice up the conversation ;-)

@maaartinus Behavior of tabs is not sufficiently standardized.

Tabs needn't behave. Nor do other chars. They're no children, they're just part of the source code. It's up to your editor to display them the way you want.

I have a huge problem with tabs in diffs in GitLab

it displays them using width=8

which often pushes code so far right that I have to scroll

while the IDEs used by teammates all display with width=4, so they don't notice the difference soon enough

@Vogel612 Nope

That's a pitty. Actually, so does my git in the console. But that's a small price for indenting with a single thing, rather than some stupid number of spaces.

8:52 PM

I never count the spaces

my IDE does it for me. Vim too

press Tab once, get 4 spaces, and everybody sees exactly what I see

Sure, but when you move using the cursor keys, it goes where it shouldn't. The real problem is IMHO people indenting with 2 spaces. For me, it's far too few and I can see nothing there.

Oh... We're at Tabs vs Spaces again

(Spoiler: Spaces wins)

Sure, that's the more important thing about computer science.

1. It wouldn't take forever, just 10 hours. :) 2. Have you tried combining the file openings, e.g. with open("Output.txt", "w") as result, open("bedgraph2.txt") as file1, with open("bedgraph1.txt") as file2: and doing the processing then? I'd guess you're spending a lot of overhead on that. 3. This question is better suited to Code Review. — TigerhawkT3 14 secs ago

pretty nice perl code in question by new user

9:01 PM

Anyone here experienced with Hibernate or GORM?

@maaartinus Scala standard is two space tabs. I haven't had any problem adapting.

@janos - FYI, reading your meta answer to the election question.... not all mods are re-running ... ;-)

^^^ no.....

who's not?

whaaaa?

tis true...

@Donald.McLean I'm afraid, Java standard is 2 spaces as well. But I really can't read it if if a method gets a bit longer.

9:03 PM

I guess you already discussed this here

yup, some transcript in there somewhere.... digging

I'm sad to learn ;(

@janos - I expect and hope that the opening will create a fresh impetus in the site. It will also allow me to kill this particularly bad record.....

@QPaysTaxes Python has an (unconventional) ternary operator as well

9:06 PM

@QPaysTaxes That's what all Java code I've ever seen uses.

@QPaysTaxes no, four spaces.

@rolfl true, not so good for you

but I'm sure you're disciplined enough to get out of that anyway

Not sure if this is Java standard, but I'm afraid, it is: google.github.io/styleguide/…

I actually wanted to skip a day to avoid Fanatic

but then I forgot :)

9:09 PM

^ that

@maaartinus / @QPaysTaxes - the 2 vs. 4 space depends largely on local rules. The google java code conventions is 2 spaces

the official java one is 4

No, @QPaysTaxes is wrong

@QPaysTaxes You're right! I've just found it: oracle.com/technetwork/java/codeconventions-150003.pdf

@QPaysTaxes company policy overrides industry policy..

Oracle/Sun has withdrawn their standard

no exceptions

9:10 PM

well, I imagine being a mod as a LOT of work. So it's not really a shocking decision

Right, the old one by sun is terrible. Google made IMHO everything better, except for this.

oracle.com/technetwork/articles/javase/codeconvtoc-136057.html

Oracle's page ^^^

But, @QPaysTaxes - I find that you make very strong, emphatic, statements that are never really as clear-cut as you make them sound

@QPaysTaxes TS ?

@Vogel612 - about the XPath things....

@rolfl found Filters.element()

9:13 PM

XPath can return all sorts of content, including Integers, etc,

You might consider giving an @see Filters in the class-level javadoc of Filter.

basically I found the filters in a code-example on the wiki-page about XPath considerations...

OK, that's a good idea.

@Vogel612 github.com/hunterhacker/jdom/issues/146

/me likes

@QPaysTaxes WOuldn't the actual Java source code be better?

In which case, who needs braces:

    /**
     * Returns the index of the first occurrence of the specified element
     * in this list, or -1 if this list does not contain the element.
     * More formally, returns the lowest index <tt>i</tt> such that
     * <tt>(o==null&nbsp;?&nbsp;get(i)==null&nbsp;:&nbsp;o.equals(get(i)))</tt>,
     * or -1 if there is no such index.
     */
    public int indexOf(Object o) {
        if (o == null) {
            for (int i = 0; i < size; i++)
                if (elementData[i]==null)
                    return i;

@rolfl Meh, in Java source they also don't always have whitespace everywhere and are not always using braces, etc.

@QPaysTaxes Most of it is, but some parts are written in C I believe either for performance reasons or platform specific reasons

9:19 PM

@QPaysTaxes depends on how you want to define Java...

@QPaysTaxes How can you be so confident about things you say about Java standards when you don't even know Java has Java source code?

monkey grumpy today?

@QPaysTaxes that argument is somewhat invalid...

yeah... apparently

@QPaysTaxes - have a look at: grepcode.com/snapshot/repository.grepcode.com/java/root/jdk/…

hmm... NoClassDefFoundError..

And also a lot of unbraced 1-liners.

9:24 PM

@Vogel612 haha so you put your plan to execution!

yes I did, and he opened an issue for me :)

@QPaysTaxes No, but you know the standards, and that is against both the oracle, and google ones.

9:26 PM

hmm... @rolfl does JDOM2 expect me to provide Jaxen?

@Vogel612 If you use XPath, yes. It is an optional dependency in the maven pom, and it is available as part of the package download on github.

A lot of people surprisinly don't use xpah

well it depends so much on what you need to do..

@rolfl I totally read "maven pom" as "maven porn"

maybe you want to link to the github organization instead? then again jaxen is separate now, IIUC..

it has moved to.... cafeconleche.org/jaxen

2.0.6 uses jaxen 1.1.3, right?

well it's what the pom says.

@Vogel612 2.0.6 uses the lates.... I thought that was 1.1.6

I pushed a bunch of performance fixes in to them at one point.

9:52 PM

and it doesn't work with 1.1.6 (at least not for me)

let me just retry with 1.1.6....

		<dependency>
			<groupId>jaxen</groupId>
			<artifactId>jaxen</artifactId>
			<version>1.1.6</version>
			<optional>true</optional>
		</dependency>

@QPaysTaxes :)

hmm... yes I was actually just too retarded to do it right...

and I'm probably overcomplicating this....

Someone ready for a flame? I consider the groupId/artifactId rather stupid. Couldn't it (at least 90% of time) be called simply called by the package?

This would make the jar search pretty superfluous.
