handling lists in perl
not really on the topic but... I'm not very good at perl (or anything else ) and could maybe sort it but perhaps there is an extension that does it. I have an list of pairs (1=>8,2=>20,6=>100,15=>100) and an array of unique numbers (1 21 100 8 15 22 6 12 15 ) I want to see what pairs can be satisfied from the array of numbers, send that list to a file and also to another file the left over numbers. mick -- Key ID4BFEBB31

Start by converting the "array of unique numbers" to a hash (associative array, dictionary). That way, you can quickly look up which numbers are in, or not in, the data set. Next, set up a second hash to record which numbers have been matched (vs. which have not) in the following step. It starts out empty. Now, iterate over your "pairs". If both members of the "pair" are in the first hash, then write the pair to the appropriate output bin, and add both numbers to the second hash. When that's finished, you want to find out which numbers from the first hash are not present in the second hash. So, iterate over the keys of the first hash, and any key that is not also in the second hash, write to the appropriate output bin. This can be done in any language that has hashes (associative arrays, dictionaries) and the ability to iterate over a list. Perl certainly qualifies, if that's your language of choice. Python and Tcl can also do it quite easily. Even bash could do this, although it would be slow, and would not be my first pick. If you need help actually *writing* it in Perl (or whatever language), you should ask for help in a language-specific mailing list.

Re: Most reliable dual band driver/chipset
In regard to my issue below: Trying to find an internal Intel based card with remote antenna. I have Linksys USB wifi adapters and they work, but not dual band. Not really necessary, but why not use everything available. Not a laptop and not a heat issue. Something in the hardware or driver seems to leave this adapter in some unstable state that requires a cold start, either disconnecting the adapter from USB, rebooting the computer and sometimes just unloading and reloading the driver. Very irritating since it works very well when connected, just unreliable. Sometimes it'll stay connected for days, sometimes just for a few minutes.

Installing Java 8 on a Google Compute Debian (Jessie) instance
I'm endeavoring to get Java 8 onto our development instance, so that the Tomcat environment there matches that of our cluster nodes, and apg-get is not cooperating. This particular instance is a Bitnami SVN/Trac server, with Tomcat 8 added to it, and running independently of the Apache server that came with SVN and Trac. I tried what was given at https://stackoverflow.com/q/50919305/3654526 and it didn't work.

Hardware detection issue with debian
I can not do this via bur report because I could not select a valid package. I have researched this and was unable to find a solved case under exact condition. The issue was mostly discussed as an mtp or mounting problem, but I dug a bit farther into the problem. When it comes to a certain model, hardware is not even detected. Thank you for all your dedicated work, Mo Following is the issue When connecting a "Galaxy S3 mini" via usb, it is not detected at all; however if connected during installation, it is temporarily detected as a "usb mass storage device" before CDrom is detected.

it is not exactly clear if you want to test the key or the value of the
pairs, but I assume you are after the values.

This is a standard/classic array
> I want to see what pairs can be satisfied from the array of numbers,

so iterate over the hash and check for matches in the array
my %hash = ( 1=>8,2=>20,6=>100,15=>100 );
my @array = [1, 21, 100, 8, 15, 22, 6, 12, 56];
foreach my $key (keys %hash) {
if ( @array =~ /$hash[$key]/) {
print "key $key with value " . $hash{$key} .
" is in the array of values\n";
}
}
result
key 6 with value 100 is in the array of values
key 2 with value 20 is in the array of values
key 15 with value 100 is in the array of values
key 1 with value 8 is in the array of values

Key Exchange Algorithms. Should be documented in ssh_config(5) and sshd_config(5). The important point is that the client will have a list of these things, and the server will have a list of these things, and there must be at least *one* in common between the two lists, or else communication will not occur.

The reason the '-t jessie-backports' option is the right solution is that openjdk-8 requires a newer ca-certificates-java than what is in jessie. In a default backports configuration, packages from the backports repository are ranked lower than from the stable repository. Another option would be specify the precise version of the ca-certificates-java package like this: apt-get install openjdk-8-jdk ca-certificates-java= It is also possible to do this: apt-get install openjdk-8-jdk ca-certificates-java/jessie-backports But those are less robust than '-t jessie-backports'. Of course, there is a possibility that other dependencies get pulled in from jessie-backports to accomplish the operation, so that must be weighed as well. Regards, -Roberto -- Roberto C. Sánchez

I checked and it seems the right answer is
my %hash = ( 1=>8,2=>20,6=>100,15=>100 );
my @array = (1, 21, 100, 8, 15, 22, 6, 12, 56);
foreach my $key (keys %hash) {
for ( @array ) {
if ($_ eq $hash{$key} ) {
print "key $key with value " . $hash{$key} .
" is in the array of values\n";
}
}
}

I'm not very good at perl (or anything else ) and could maybe sort it
but perhaps there is an extension that does it.
I have an list of pairs
(1=>8,2=>20,6=>100,15=>100)
and an array of unique numbers
(1 21 100 8 15 22 6 12 56 )
I want to see what pairs can be satisfied from the array of numbers,
send that list to a file and also to another file the left over numbers.
The three canonical Perl (version 5) books are:
1. Learning Perl -- gets you up the initial learning curve:
http://shop.oreilly.com/product/0636920049517.do
2. Perl Cookbook -- "real world" code examples with explanations:
http://shop.oreilly.com/product/9780596003135.do
3. Programming Perl -- the language reference:
http://shop.oreilly.com/product/9780596004927.do
I learned Perl via the first two. I didn't get into the third until I
was well on my way.
If you just want to "get it done", here is a starter script:

$ cat 20181218-1334-mick-crane.pl
#!/usr/bin/env perl
use strict;
use warnings;
my %pairs = (1 => 8, 2 => 20, 6 => 100, 15 => 100);
my @unique = (1, 21, 100, 8, 15, 22, 6, 12, 56);
open (my $fh_satisfies, ">satisfies.txt") or die $!;
open (my $fh_leftovers, ">leftovers.txt") or die $!;
for my $k (@unique) {
my $fh = exists $pairs{$k} ? $fh_satisfies : $fh_leftovers;
$fh->print($k, "\n");
}

I had luck with jmtpfs when nothing else worked a while back. Things didn't work instantly out of the box, but I've forgotten what I had to do related to some rational reason already known out and around on the Web. The fix, including their suggestion to even use jmtpfs, was probably something that pulled up thanks to whatever errors I was receiving at the time. :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *

Anyhow I am wondering why 8.10 doesn’t work like it should? It’s > technically the last official PowerPC 32 release... I do not remember: is it between Debian 7 and Debian 8 that firmware inclusion in distros in general and in Debian in particular changed? In the past some firmwares (non-free stuff) were installed with (or part of) the linux kernel package and that changed with the next Debian release. So there a possibility that Debian 8.10 works as it should and you have to install firmware(s) required by your hardware: https://wiki.debian.org/Firmware
