Hi useRs, I am trying to calculate the Sharpe ratio with "sharpe" of the library "tseries". The documentation requires the univariate time series to be a portfolio's cumulated returns. In this case, the example given data(EuStockMarkets) dax <- log(EuStockMarkets[,"FTSE"]) is however not the cumulated returns but rather the daily returns of the FTSE

Hi, I have two connections to the Internet. I implemented the load balancing as described in chapter 4.2 "Routing for multiple uplinks/providers" The problem that occurred is that the client applications like Yahoo Messenger or even PuTTY (SSH client) are loosing the connection very often. Does anyone experienced this problem? Does anyone knows an workaround for this problem?

Hi I''ve a stupid question. How can I shape upload using IMQ? Instead of putting a rule in iptables in PREROUTING should i use POSTROUTING? And another question is, can I make routing rule based on ip addresses assigned by iptables to an imq device? The idea is, let''s say i have some rules in iptables like: -t mangle -A PREROUTING -s 192.168.0.0/16 -j IMQ --todev 0 Can i route

Hi, This is the first time I've come across this: pid 11415 (ipfw), uid 0: exited on signal 11 (core dumped) The core dump landed in root's home directory in one of my jails. Has anyone seen this before? Should I be concerned? chkrootkit says nothing. (How trustworthy is its output? ;-) Thanks. Cheers. -- Ng Pheng Siong <ngps@netmemetic.com> http://firewall.rulemaker.net

I have managed to get it set up so that I can now use net commands to mount shares from my linux box onto my windows box. But I still don't see an icon for my linux box on the network niehborhood. I have waited and waited and tried what seems like everything but can't get that stupid icon to come up. Any ideas??? Scott

Hello, We are using btrfs filesystems in our infrastructure and, at some point of time, they start refusing to create new subvolumes. Each file system is being quota initialized immediately after its creation (with "btrfs quota enable") and then all subfolders under the root directory are created as subvolumes (btrfs subvolume create). Over time, these subvolumes may also be

So this is just a general question, Is Asterisk really good? Reliability? Functionality? Customization's? I am coming from a Nortel world, were you pay for everything, and you can't delve into the software. But it seems that customization would be a great thing. Like, setting up a war-dialer to customer lists, incoming/outgoing faxes (that's possible with Asterisk, right?) and

Well I am entering into a realm that I don't know. 3 sites with Asterisk 1 site with Nortel Asterisk/Sip calls working fine between the 3 sites. Asterisk to Nortel set calls working fine. (call comes from asterisk to nortel and rings telephone, people answer and talk happens, hangup call clears) Nortel to Asterisk. Set on Nortel gets a busy signal. Any suggestions on what to look

Hey guys, I installed tinc on a linux server which connects to the internet. That server is linked via a wireless link with a Windows 2000 workstation. I installed tinc on the windows box too, and the vpn works neat. The only problem is I don't know if the windows tap driver is able to forward unknown IPs to a gateway. This is because if I try to ping 10.0.0.1 which is just another

I need to be able to allow specific system accounts to ftp to a box. As far as I can tell I have to give them a shell in /etc/passwd (i.e. /bin/bash) in order for their ftp login to work. I do *not* however want them to be able to log into a shell or ssh session. I cannot restrict by IP. What's the best way to accomplish this? Thanks, Scott

Hello, I intend to migrate a mail server with Maildir from wu-imap to dovecot imap. Using horde/IMP, users can not access their imap forders, as wu-imap created Mail directory that holds all created folders. Dovecot could not detect the mail directory so I had to put default_mail_env = ~/Maildir in dovecot.conf. Before I begin to read the source-code of dovecot or try to migrate the the
