I first ran into the use of monte carlo analysis looking for forward financial analysis - - where it shines. It looks like it can be an excellent tool, albeit not simple nor easy, but maybe some of the negatives could be hidden in the software. For me the idea of being able to quantify with a reasonable certainty highly complex models is very attractive.

( I do love Monte Carlo also :) ) A monte carlo system sets up all the foundational parameters. So there is a formula for every variable. Every variable has its distribution and every distribution has its skewness and and and (it can get very very complicated). Then one defines the limits on the distribution (setting parameters) which is followed by an attempt at solving for all the unknowns given the area of input for each. Monte Carlo systems enable one to define the either hugely transitory or the undefinable. The random number part comes into where if variable 's' in item 'aaa' has a probable range of '2 to 7 ppm' with an 85% likelihood of being between (3.2 and 4.6 ppm) well now an number between 3.2 and 4.6 can be used for 's' value in item 'aaa'. Then the amount of item 'aaa' is entered and the totals of all listed values for all items are summed. The summed items are compared to the required minimums/maximums/desired values for each value. The overall outputs are compared and then adjustments are made to have a combined grouping that meets desired outcomes. Its a fairly straight forward process when one eliminates the variation possible in each of the variables. This elimination itself introduces new variables which are most often overcome by a planned excess. (I don't like spending more than I have to in trying to get the job done so I'm being quite a bit anal in the development of the tool.) Thanking you for your assistance. Dee

Not recognizing added RAM
by Evan Leibovitch 10 Oct '18

10 Oct '18

Hi all, I thought I would know how to handle this but it turns out that I don't. I just added two new sticks of RAM to a system but it's not recognized by the BIOS or OS. # inxi -m Memory: RAM: total: 7.74 GiB used: 2.93 GiB (37.9%) Array-1: capacity: 16 GiB note: est. slots: 4 EC: None Device-1: DIMM_A1 size: 4 GiB speed: 800 MT/s Device-2: DIMM_A2 size: 4 GiB speed: 800 MT/s Device-3: DIMM_B1 size: 4 GiB speed: 800 MT/s Device-4: DIMM_B2 size: 4 GiB speed: 800 MT/s So Inxi sees all 16GB (as does memtest) and yet in the first line it shows RAM total at 8. dmidecode output is below Motherboard is an Asus F2A85-M. BIOS has been reset to defaults but not updated since the mobo was purchased. OS is current Manjaro KDE. The website specs say it can take 64GB. Is updating the BIOS necessary or are there other solutions? All help is greatly appreciated. - Evan ------------------------------------------------------------- # dmidecode -t 17 # dmidecode 3.2 Getting SMBIOS data from sysfs. SMBIOS 2.7 present.

FSOSS 2018 registration
by D. Hugh Redelmeier 05 Oct '18

05 Oct '18

The registration page just went up. - Oct 25 & 26 (Thursday and Friday) - early bird (cheap) registration ends Oct 15. $75 for non-students, non-staff (note: any (educational?) institution is good for a discount. - seems to be at the Seneca @ York campus (I had heard that they were going to be moved; maybe next year) - for the first time it will be on the subway! I've enjoyed FSOSS for the years I've attended. I recommend it. You can even give a talk!

Re: [GTALUG] dh key exchange question.
by Mike 04 Oct '18

04 Oct '18

Got it! So you can definitely connect outbound on port 22! And yes, I was probing dreamhost.com on port 22. They got some 'splaining to do. I suggest you might want to hit up their support folks again armed with the information that your SSH client is using: diffie-hellman-group-exchange-sha1 OR diffie-hellman-group1-sha1 for key exchange, ssh-dss for host key, and aes128-cbc and hmac-sha1 for session encryption. Good luck, Watson! Let us know what explanation they offer... Cheers, Mike

dh key exchange question.
by Karen Lewellen 04 Oct '18

04 Oct '18

Hi folks, The accessible ssh client I use provides a way to send dh keys when I use ssh TELNET to reach a location. I have a bell dsl account, and since the first of July I have not been able to reach dreamhost who hosts my office shell. While I have not ruled out Bell as the problem, it started one day when they claimed to have a service interruption, and refuse to discuss Linux at all, I want to see if something else might have happened. With very few exceptions, every place where I visit involving port 22 presents the same dh key exchange failure. Was openssh updated on June 29 2018? Hosting companies who use some different Linux options for their shell services, scientific for example, still work. Shellworld does too, but we use a different port for ssh and the administrator still allows most public keys. can anyone provide wisdom here? Thanks, Karen
