I want to make it ITIL-Compliant. I (optionally) want to provide the Problem and Change Management facilities within it in a way that the concerned teams and the management can find the KEDB very useful for their work also. I am going to do it entirely in PHP and JavaScript for client-side validations wherever needed.

View 13 Replies View RelatedProgramming :: Languages To Learn For Dynamic Website Design?
Nov 23, 2010So a friend and I are new-ish to linux (I am reasonably comfortable with basic /etc text editing, command admin). We are, however, completely new to programming and (x)html. We have a few (what we think are) interesting ideas for dynamic websites.Ideally we would like to develop our own course of study to get to the point where we have a basic understanding of programming so that our adventures in the programming of a dynamic website would be possible. Much of what we need learn to do is the following: use daily updated public-domain data from several other sites, manipulate that data algorithmically, which would then yield updating output on our site. Here is what I would like to do:
1. learn the basics of programming with a language that would teach good code habits and fundamental understanding.
2. become comfortable with (x)html
3. learn another language for the extension of (x)html into a dynamic data-heavy website.
Question could you please suggest a way about going about 1>2>3?Ideally the language of (1) would be something that would not be "wasted" just on web design etc. As a language, C really appeals to me. However, if learning this wouldn't lend itself to being helpful in learning another language for webdesign maybe I shouldn't use it(?).If (1) weren't to be C, what language would be funadmental enough to teach good coding but also be helpful in learning (3)
Programming :: Database Design Using IDs As Opposed As Candidate Keys As Primary Key
Jul 27, 2011Self learner developer since about 2 years, I'm trying to understand deeper how to design a database in the best and most efficient way possible.Reading about UML design, I've found this: Do not automatically add ID numbers(surrogate keys) or substitute keys to a table until you are sure that:
-There is at least one candidate key (before the surrogate is added),
-the table is a parent in at least one association, and
-there is no candidate key small enough for its values to be copied many times into the child table.
Until then, I've always did this (I mean using ID) to identify my rows.So my questions are:
1. Why should we avoid using ID to identify rows?
2. Candidate keys add some weight to our database, and this can huge if we have millions of records, so why should we use these over surrogate keys?

Server :: Set Up Squid3 Proxy As A Transparent Proxy & Iptables Config
Feb 23, 2011I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?
Ubuntu Networking :: Setting Up Web Design Test Server?
Dec 19, 2010I do not know much at all when it comes to setting up hardware--servers, switches, etc.
I have a 1701HG 2Wire wireless router that I use for my home network. I have an old pentium 3 tower that is just laying around, and I want to be able to host my projects on it for testing. Basically, I just want to be able to do everything on my laptop and then upload it to the server for testing.
I have set up an Ubuntu LAMP server on the desktop and am able to do everything I want via SFTP; however, I want to be able to type in "projectx.local" in a browser on my laptop to go to one test site, "projectz.local" to go to another, etc.
Is this possible, since I do not have the server set up as my gateway? It is merely connected to the router like everything else.
Ubuntu :: Create A Reverse SSH Proxy For A Telnet Process
Mar 12, 2010I have a project that I'm working on now that is using Ubuntu 8.04LTS to create a reverse SSH proxy for a telnet process. We have the box logging in with RSA keys so that it can automatically connect to the SSH host on our end. We are using autossh to keep the connection up and running.
We have rolled out 3 of these and they are working very well. We ghosted the original, changed the hostname, changed the IP info, and regenerated the SSH keys. Now I need to clone 35 more. I want to try to do this as efficiently as possible and can script the changes in the hostname, IP, ect.
Can I batch create RSA keypairs on my workstation and then copy them over as a part of the batch? My current other option is to login to each of them and generate the pair. I would like to just install the drive and ship it and not even have to boot it up.

View 11 Replies View RelatedUbuntu :: Compiz Acts Strange After Reboot?
Sep 6, 2010Pretty sure it's Compiz, as when it's acting up if I try something simple like switch workspace, things lock up. A gdm restart can recover from that condition.So after a reboot, log in and start something benign like Firefox (doesn't matter what you start). The window will 'paint' from the bottom up over a period of a few hundred milliseconds. A significant fraction of a second, though. All window operations have this delay.A small window near the top of the screen exhibits a delay as if the entire screen below it had to 'repaint' before it can be displayed.
If you then lock the screen and return to the same session, everything seems to work as normal.lternatively, you can log in as another user... same effect there... return to session 1 and everything is normal. Return to session 2 and everything is normal.It seems that returning to gdm's login screen and back fixes it.So just when you log in for the first time, this annoying paint issue appears.As mentioned, if you try to use any sort of compiz effect, that session is frozen.Usually, things are ok - even if you log out and back in - until the next reboot.
When this first started happening, I would log out/back in and the effect would sometimes fix itself. But not always. The key difference between that and the 100% fix above is that you don't log out above. The session remains logged in. Also, I tried switching to a console and restarting gdm. That also works sometimes, but not always. I would also try starting Nvidia X Server Settings tool before logging out and it seemed like that increased the chances of success. But I'm not sure it did. It does seem that once it's fixed, it stays fixed until the next reboot.Sorry for the lengthy post, but I warned you I wasn't sure how to describe it.

Programming :: Writing A Daemon That Can Update Itself?
Apr 27, 2011I have written a daemon server. I would like to add the ability for the daemon to update itself. That is, it should be able to download the latest version of the code (when it receives a signal from a client) and then restart itself. I am stuck on getting the daemon to restart itself. The problem is killing the old daemon without killing the process that is starting the new daemon. In my latest attempt, the daemon that is updating itself runs a program in a subshell (using system) that starts a restarter daemon that runs the original daemon (again using system) with the restart command option. With the restart option, the new version of the daemon sends a terminate signal to the old version. Obviously, when I run the original daemon manually with the restart option, it restarts reliably. I figured that issuing the same restart command from a daemon would adequately isolate the process doing the restarting from the program being restarted. Using ps, I can see that the daemon does actually restart. However, the client locks. In fact, a few times, the OS locked and I had to reset.
