How I wasted my Sunday:

A programmer I know claimed that his Nodejs app was lightweight since it only relied on 2 dependencies (express and mongodb)

So I wrote a script to recursively transverse the npm dependency tree and count the number of dependencies there actually is

Installing those 2 packages alone means your app depends on 73 pieces of software in total

In conclusion, nothing written in Node is ever lightweight

Oh yeah, it was also Easter I guess

Today I heard my boss counting 14,15,16,17 multiple times, then he said OMG 4 days, I asked him about the issue
So he said the easter will make 4 non-working days, I was surprised
Then he said yes
Turns he was counting Saturday and Sunday 😂

If the clock is not complicated enough, with DST and timezones.... holidays and red days is even more complicated..... (a perl sub which returns all red days for sweden. It does not return any holidays thats always saturday or sunday)
Requires Date::Calc and Date::Easter

What a mess dates and times become..,

sub GetHoliDayList() {

$yeartocheck = $_[0];

$holiday{'1-1'} = '1';
$holiday{'1-6'} = '1';
$holiday{'5-1'} = '1';
$holiday{'6-6'} = '1';
$holiday{'6-24'} = '1';
$holiday{'12-24'} = '1';
$holiday{'12-25'} = '1';
$holiday{'12-26'} = '1';
$holiday{'12-31'} = '1';

($eastermonth, $easterday) = gregorian_easter( $yeartocheck );
$hea = int($eastermonth)."-".int(int($easterday) - 2);
$heb = int($eastermonth)."-".int(int($easterday) + 1);
$holiday{$hea} = '1';
$holiday{$heb} = '1';

($year,$christskytravellermonth,$christskytravellerday) = Add_Delta_YMD($yeartocheck,$eastermonth,$easterday, 0,0,39);
$chstv = int($christskytravellermonth)."-".int($christskytravellerday);
$holiday{$chstv} = '1';

if (Day_Of_Week($yeartocheck,6,19) == 5) {
$holiday{'6-19'} = '1';
}
if (Day_Of_Week($yeartocheck,6,20) == 5) {
$holiday{'6-20'} = '1';
}
if (Day_Of_Week($yeartocheck,6,21) == 5) {
$holiday{'6-21'} = '1';
}
if (Day_Of_Week($yeartocheck,6,22) == 5) {
$holiday{'6-22'} = '1';
}
if (Day_Of_Week($yeartocheck,6,23) == 5) {
$holiday{'6-23'} = '1';
}
if (Day_Of_Week($yeartocheck,6,24) == 5) {
$holiday{'6-24'} = '1';
}
if (Day_Of_Week($yeartocheck,6,25) == 5) {
$holiday{'6-25'} = '1';
}

return %holiday;
}
