Problem 3:
The prime factors of 13195 are 5, 7, 13 and 29.
What is the largest prime factor of the number 600851475143 ?
import math pSieve = [] max = math.floor(math.sqrt( 600851475143 )) l = 0 i=2; while i<max: ii = math.floor(math.sqrt( i )) found = False j=0 while j<len(pSieve): if ( pSieve[j] > ii ): break; if (i % pSieve[j] == 0): found = True break; j+=1 if found == False: pSieve.append(i) if (600851475143 % i == 0): l=i i+=1 print l |

This was tested on PSv2.
I kept getting Completed — Failed — Died and
CRRBF1253I Build Forge: Process for id [] [B] died unexpectedly.
After checking out http://www.ibm.com/support/docview.wss?uid=swg21634022 and
http://www.ibm.com/support/docview.wss?uid=swg21634022 there was still no solution in sight.
Finally I was able to solve the issue in my buildforge instance by disabling *sticky* in my inline libraries. I was also using .bset server and .bset buildserver. My theory is that some interaction between the sticky and the bset were conflicting.
Just in case some poor sap like me gets stuck with errors

If I give you scrabble tiles and a dictionary, determine the valid words
from your collection of tiles.

There’s probably a better way to do this, I am interested
to see what other solutions there are.
Short two liner for ANT zipping on Windows.
>build.xml echo ^<project^>^<zip destfile=^"zipFile.zip^" basedir=^"toBeZipped^" /^>^</project^> ant |
Because Windows doesn’t apparently have a zip command line.
Updated here for Windows without ANT.
Wanting to use the messages in ICU4J, I was lead to believe one needed to run the command:
genrb root.txt
This produces root.res.
However using the following snippet results in the error message below:
UResourceBundle urb = UResourceBundle.getBundleInstance("Your package path","root");
>Data file yourPackagePath/root.res is corrupt - ICU data file error: Header authentication failed, please check if you have a valid ICU data file
“Cookie cannot be resolved to a type”
I swear I’ve seen this error like 5 times in eclipse now, and I have yet to learn my lesson.
If this error originates from a jsp file, your project doesn’t have a valid target webserver (in my case – tomcat).
So just make sure it’s configured correctly.
Thought I’d just leave this here,
because almost all top searches in google were useless to me.

I was on IRC.. and noticed this link.. http://mywiki.wooledge.org/BashPitfalls,
if I had only known earlier…
Tons of useful information on Bash Pitfalls… as well as tons of habits to change… :/
My error was specifically #22,
cmd1 && cmd2 || cmd3 where I had assumed cmd2 is going to exit 0.
In most of my usecases… my command is in the form of cmd1 || sleep # && cmd3, I just naturally assume sleep is going to return 0.
Well, luckily for me, it has worked for the most part… but definitely need to change a number of my scripting habits…
With my new job, I haven’t had much time to add much to this website.
So here’s this small perl script I wrote that sends a summary of the weather in SMS format from my iPhone daily.
There was a need, so I figured why not help out those who need the weather forecast =].
use LWP::Simple; use JSON qw( decode_json ); my $lastRun = 0; open (MYFILE, 'weatherSMS_LastRun'); while (<MYFILE>) { chomp; $lastRun = $_; } close (MYFILE); my ($S,$M,$H,$d,$m,$Y) = localtime($lastRun); my ($S2,$M2,$H2,$d2,$m2,$Y2) = localtime(time); if ( $Y2 == $Y && $m2 == $m && $d2 == $d ){ exit 0; } $json = get("https://api.forecast.io/forecast/APIKEY/LATITUDE,LONGITUDE?units=ca&exclude=currently,minutely,hourly,flags"); my $decoded = decode_json($json); #ensure we can write the file open(F,'>weatherSMS_LastRun') || die "Could not open file to mark execution"; print F time; close(F); my @timeslot = @{ $decoded->{'daily'}{'data'} }; my $forcast = ""; foreach my $f ( @timeslot ) { my ($S,$M,$H,$d,$m,$Y) = localtime($f->{"time"}); $m = $m + 1; $forcast .= "$m/$d: ".sprintf("%.3f",$f->{"temperatureMin"})."-".sprintf("%.3f",$f->{"temperatureMax"})."C ".$f->{"summary"}."\n"; } #printf($forcast); `/Applications/biteSMS.app/biteSMS -send -carrier PHONENUMBER "$forcast"`; |
In order to execute this daily, the following plist was used:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.joshho.weatherSMS</string> <key>LowPriorityIO</key> <false/> <key>Nice</key> <integer>1</integer> <key>AbandonProcessGroup</key> <true/> <key>OnDemand</key> <true/> <key>ProgramArguments</key> <array> <string>/usr/local/bin/perl</string> <string>/location to perlscript/weatherSMS.pl</string> </array> <key>StartCalendarInterval</key> <dict> <key>Minute</key> <integer>0</integer> </dict> </dict> </plist> |
Submit it to be executed hourly by running `launchctl load [path to plist]`

Edits were made to cover the fact that your phone may not always have internet.
(It may be locked/sleeping – which may turn off the wifi?)
