Q: Very slow graph walking. Can you give me hints to make it much faster?

I've a problem. My code is very-very slow. Could you give me hints how I can make it much faster? The function is: for (stdext::hash_map<unsigned __int32, CVertex*>::iterator it1 = graph.begin(); it1 != graph.end(); it1++) { for (std::vector<CVertex*>::iterator it2 = it1->second->getNeighbo...

@skiwi - got a sec?

    private static final Comparator<String> LONGEST_FIRST = buildComparator();
    private static Comparator<String> buildComparator() {
        Comparator<String> byLength = Comparator.comparingInt(value -> -1 * value.length());
        return byLength.thenComparing(Comparator.naturalOrder());
    }

^^^ How to make that a Java-8 1-liner?

I cannot get the following to compile:

private static final Comparator<String> LONGEST_FIRST = Comparator.comparingInt(value -> -1 * value.length())
         .thenComparing(Comparator.naturalOrder());

It 'loses' the implied type of <String> On the comparator

Q: What is the most efficient method of performing the FIZZBUZZ test in SQL Server?

This may not be completely on-topic, however it's a slow day here. Is there a more efficient method of obtaining a list of numbers from 1 to 49 with a column containing the words FIZZ when the number can be evenly divided by 3, BUZZ when the number can be evenly divided by 5, and FIZZBUZZ when t...

Q: find directories containing jar files and call other program to scan them for vulnerable versions

I wrote a python script to collect a list of directories containing third party libraries and submit them all to dependency-check, a program that compares library versions to known-vulnerable third party libraries. Here are the tests: from unittest import TestCase import unittest import run_ch...

@Phrancis: thanks for posting a bounty on this question -- it was interesting and I'd have overlooked it otherwise!

A: Boost Python converter for std::tuple

There is a way to simplify this by using only a single wrapper template. First, here's the single template: template <typename P, typename R, typename ...Args> struct tupleconvert_wrapper { P params; tupleconvert_wrapper(const P& _params):params(_params){} R delayed_dispatch() { re...

I'm here... now

@rolfl If nothing else fixes it (that is, two lines work), then use a <String> type witness

Java 8 is sometimes too powerful...

I've had occasions as well where the type was not captured correctly

@Malachi Not here. I made sure @Phrancis saw it though.

Malachi

@RubberDuck I saw his comments on the question...lol

Lol @phrancis clearly not! — Max Vernon 20 hours ago

I'm mistaken that interrupts = 16-bit assembly, right?

Edward

Yes -- interrupts are used on any machine including the OP's 32-bit Linux box.

Phrancis

@Edward I'm blown away the OP is still around after posting this to SO and being migrated over 2 years ago (see the other recent answer)

Jamal

9:37 PM

I'm glad that misconception is finally cleared, then. I'll fix that part.

Edward

@Phrancis Yes, that's pretty nice, isn't it?

I was hoping somebody would post something like my answer so I'd learn a new technique.

But then I had some time and figured it out myself.

Fun!

Phrancis

@Edward Yes indeed. I'm not sure which to award, I might let it auto-award so the community decides.

Cuz I don't speak C++ lol.

Edward

@Phrancis My main reward was in figuring out an answer.

Although imaginary internet points are a valued resource, too.

Phrancis

@Edward I like your spirit :)

Edward

@Phrancis Speaking of spirits, is it time for champagne yet?

I started early and had some with lunch. :)

@Edward 16:42 here... But I got some spiced rum to pass the time ;)

Edward

I have some eggnog that's in dire need of rum.

Phrancis

Oooohhhh I think I got some eggnog too

Edward

Actually, I'll have to see if the eggnog has gone bad -- I can optimize the recipe to just rum.

You would like my t-shirt right now, methinks. Let me see if I can selfie it

Love it!

@Edward Hahah nice

@Edward Perfect pun for heathen holiday fun ;)

A: Karate Chop Kata

Even though it matches the spec, Chop isn't a very good name for what this function does. IndexOf would be a better name. Ubound(Arr) gets called in this code a lot. It happens more than enough to declare a variable for it. All of the parameters are being implicitly passed ByRef which isn't nice...

If I'm not here to get my hat, HAPPY NEW YEAR CODE REVIEW!
