  • Problem with understanding how to start

    - by Coolface
    Okay, this might be a little off-topic but i try anyway. Sorry to bother. So i'm working as sysadmin for at least 5 years now and i quite enjoy IT field in general. Somehow i was never interested in programming much but always want to learn something at least easy and for personal usage. As sysadmin i need scripting skills so learn shell scripting without much problems, i also try to learn pascal, delphi, basic over time and must recent was python. Well, my problem is when i try to learn programming i just can't apply what i learn from the books to the real word. What i mean is i understand there are data structures, algorithms, variables, lib's, if-then logic, etc. but i just can't understand how to apply this things when i want to do real things. Like i want to get a something simple as parse web page, i draw a quick algorithm like get a web page, find a word on it and write a to file, on the paper everything look simple but when i get to the coding i just stuck pretty much from the start. I try read code of the real programs that just totally confusing especially big parts with many classes so i'm just quickly lost a trail what this code do. I think i just lack some fundamentals to see a big picture but don't really know what this might be? Or maybe i just don't have a passion to programming at all... My best bet was a shell scripting so i have really no problems to write complex scripts but this just not enough. Recently i was read around 5 or 6 python books because everyone say it's so easy even kid can code something but still no much luck, python is good and easy but i can't make something harder then a prodecurial style code like in bash for easy things but when i want harder things i'm still stuck. In college i was also not a math and tech guy and like to study non-tech stuff mostly like economy, psychology maybe that my problem? Anyway any advice would be greatly appriciated.

  • Understanding the Mounting of a Filesystem

    - by Tom H.
    I'm new to linux and want to check my understanding of how mounting/filesystems work. I read related manpages, but just want to be sure. I have a partition say /dev/sda5 that is currently mounted to /home with various subdirs. It is my understanding that this means /dev/sda5 has its own portable filesystem that can be moved anywhere in the main filesystem. Questions: If I unmount /dev/sda5 from /home (# umount /home) and then mount it to /var/www/ (which is empty) (# mount -t ext3 /dev/sda5 /var/www) and replace the fstab entry, with /dev/sda5 /var/www ext3 defaults,noatime,nodev 1 2 and # mount -a, Q1) are all of the contents of /home now accessible under /var/www/ (i.e. /home/username -> /var/www/username)? Q2) Are all of the permissions from the /home filesystem kept intact in this new location? Anything else I should be concerned with? Just want to make sure I don't go wipe/corrupt anything. Coming from Windows the filesystem architecture takes getting used to (though I'm loving the flexibility!).

  • Understanding: cloud-server, cloud-hosting, cloud-computing, the cloud

    - by Abel
    There's a lot of buzz about these subjects and there seems little consensus on the terms. Is that just me not understanding the subject, or is there a clear meaning for each of these terms? Are there more elaborate terms or descriptions that describe what a cloud provider has, is or offers? EDIT: rewritten question, apparently it was unclear, partially due to the bloat I added.

  • Layman's book for understanding computer networks

    - by srid
    The good thing about books targeting a layman is that it is usually very engaging to read (not dry and boring like, say, school/university books). Charles Petzold's Code: The Hidden Language of Computer Hardware and Software does this for explaining the underlying hardware in computers. Is there a similar book for understanding computer networking?

  • Understanding linear linked list

    - by ArtWorkAD
    Hi, I have some problems understanding the linear linked list data structure. This is how I define a list element: class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } } To keep it simple we say that a list are linked nodes so we do not need to define a class list (recursion principle). My problem is that I am really confused in understanding how nodes are connected, more precisely the sequence of the nodes when we connect them. Node n1 = new Node(new Integer(2), null); Node n2 = new Node(new Integer(1), n1); What is link? Is it the previous or the next element? Any other suggestions to help me understanding this data structure?

  • Understanding Zabbix Triggers

    - by Mediocre Gopher
    I have zabbix set with an item to monitor a log file on a zabbix client: log["/var/log/program_name/client.log","ERROR:","UTF-8",100] And a trigger to determine when that log file get's more ERRORs: {Template_Linux:log["/var/log/program_name/client.log","ERROR:","UTF-8",100].change(0)}#0 This trigger gets tripped when the log file gets ERRORs the first time, but then that first trigger just sits around for ever in Monitoring-Triggers. My understanding is that the next time the server checks the value of log["/var/log/program_name/client.log","ERROR:","UTF-8",100] and sees that it hasn't changed that the trigger would go away. Obviously this isn't the case. Could someone explain why this first trigger isn't going away? Ultimately my goal is to receive an email whenever ERRORs are added to that log file, but I would like to understand how triggers are working first.

  • Understanding RewriteCond in .htacces files

    - by Paulo Bu
    I'm having problems understanding how RewriteCond directive works. So far, it's pretty clear that it compares to strings to apply a RewriteRule. I have this file: <IfModule rewrite_module> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ app_dev.php </IfModule> This works for me but I don't know why it works. So far in the RewriteCond directive I understand: if the value of REQUEST_FILENAME is NOT a file in the hard drive then allow the rule This doesn't have sense becouse app_dev.php after substituting is a file in the hard drive. Anyways, could someone enlighten me with this issue? I am having a very harsh time figuring out how this works.

  • Understanding IUSR_<machine> account

    - by liho1eye
    Namely how is setting read/write permission for this account different from giving read/write access in the IIS (Windows 2003, so it should be IIS6 if I am not mistaken). Here is the issue: It looks like we had a security sweep and as a part of that IUSR account lost write access everywhere. A whole bunch of legacy ASP sites didn't like that at all... My very surfacish understanding is that it is enough to deny write access in the IIS console to protect a website from someone just dropping random files into it, and IUSR access only has effect on the application scripts running server side, and thus can be safely given write access back. edit: The applications in question obviously require write access to their own web folders, otherwise this wouldn't be an issue at all. Question is how to configure IIS/application to both satisfy security and make them work. My first instinct was to change account which is used to run the app pool. However that is already set to NETWORK_SERVICE, and that guy already has full access to folders in question.

  • Understanding Git's version control

    - by georgeliquor
    Is there a way to go through different commits on a file. Say I modified a file 5 times and I want to go back to change 2, after I already committed and pushed to a repository. In my understanding the only way is to keep many branches, have I got that right? If I'm right I'm gonna have hundreds of branches in a few days, so I'm probably not understanding it really. Could anyone clear that up please?
