View 1 Replies View RelatedI am currently running a lot of simulations and am always interested to speed things up a bit. My workstation has 2 hdds, 1 ssd-drive (sda1) and 1 mechanical platter drive (sdb1). Of course, most of my data are on the mechanical drive and the ssd is mostly used for booting.
However, to speed things up a bit, I wonder if it is possible to create a pointer or link in a directory residing within the mechanical drive, which will write the data, in reality, to the ssd instead. For example,
Code:
/home/me/sims/data/dump
would normally reside on sdb1. But I would like it to point to a mount point of the ssd instead, e.g.,
Code:
/ssdtemp/dump

View 1 Replies View RelatedI just installed FC12 x86_64. After a clean install I found that httpd, mysql, svn, svnadmin, etc are already installed. I still need to install and configure tomcat running as a worker behind httpd and configure everything. But my question is about security. What do I need to do to ensure that when I start httpd and mysql that they are secure? Are there default settings that I need to change? Are there security patches I need to apply?

A friend of mine is building a data acquisition system for a vehicle that will wander through city streets and roads and perhaps even off-road places. At the end of the day, back at the garage, the data must be downloaded and, if needed, upload an update of the data acquisition program. The network is wpa_supplicant, and it was chosen an USB device, because the original computer did not had any wireless interface and do not have any other possibility. The problem is that, when the vehicle comes back, very often there is no access to the on-board computer, or the connection lasts just a few minutes.
The computer must be reinitialized so the connection is back and the scripts run completely. Sometimes the connection is made, but the guys are so used to restart the computer that they do it anyhow, and then the connection does not come up, they have to restart it again.I have being thinking, as the vehicle drives all around, perhaps finding some access points along the day, if this connection trials - and failures - are messing up something. Or, the connection instability as the vehicle approaches the garage, could be driving his scripts mad?

View 1 Replies View RelatedI have a large collection of files on a computer (tallgrass) and tallgrass is running an ftp server, which I have the username and password to. There is about 600 GB of files on tallgrass that I need access to, but I don't have a big enough hard drive. I need these data files to run a cpu-intensive calculation, and my CPU is significantly better than tallgrass' cpu, which is why I want to do it on my computer. (Tallgrass also doesn't have enough RAM.) What I would like to do is create a "symbolic link" on my hard drive that will point to the directory containing the data on tallgrass. Read-only is perfectly OK. This way I could read from mylink/data0001.dat and it would read from the file data0001.dat over ftp from tallgrass. I shouldn't have any speed issues because tallgrass is on my 1 Gbps LAN. Is there a way I can do this?

View 1 Replies View RelatedAt work I use Ubuntu and one nice thing about it is that it creates mount points for removable drives automatically.
In Slackware I can set up XFCE so that it mounts drives when they are plugged in, but only if they're already specified in the fstab (which means I must have used them and set them up in advance).
This is becoming a problem now that removable usb drives of all sorts are so common.
Recently, I started downloading data from a website that shows houses for sale. My goal is to create a website on which people can find out about the pricing over the course of time and the length of time a house remains available. I have created a MySQL database, which is currently being fed each night. At this point, I have enough data records to start analyzing and mining this data.Now I have come to the part of starting a datawarehouse. I love to use a data modelling tool, like the one from MySQL. Yet, I have a hard time finding some documentation over data modelling a data vault datawarehouse using open source tools. Pentaho looks promising, but I need to keep this low-budget. So low-budget it needs to be free. MySQL Workbench has a moddelling tool as well. Yet it does not support a data vault scheme.Has anyone any experience in setting up a datawarehouse? Or in particular a data vault datawarehouse using open source tools?

Right now to install software from source I do a ./configure && make && make install which doesn't allow for easy uninstallation (some don't come with an 'uninstall' goal, and if they do you have to keep the source around). I'd like to learn how to create binary RPMs from source tar.gz files (one reason being that it makes for easier uninstallation). I tried the following but it complains with the following errors:
Code:
$ rpmbuild -ta mysource.tar.gz
error: Name field must be present in package: (main package)
error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)
error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)
Apparently that's what happens when there is no SPEC file in the tarball. But all the tars I've tried give this same error. Is there a simple way to create binary RPMs from source files - as an example, this source tar [URL].

Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).
I was trying to do some graphing of the Disk Usage of the my root partition.
