  • Question regarding filesystems true or false?

    - by Avon
    Hello all, though I'm familiar with stackoverflow , and loving it , i've actually got a couple of questions myself about something other then programming. Here are my question Is it true that in FAT filesystems the maximum number of files per filesystem equals the number of entries in the FAT table. And is it also true that in indexed filesystems the maximum number of files per filesystem equals the number of indexblocks – 1. I'm reading some stuff and am trying to get a good understanding of it.

  • What is the difference between SoftAP and Wifi-Direct?

    - by user1129812
    I want to buy a Wifi Dongle that, besides acting as an ordinary Wifi client, could change its mode to work as an Access Point too. Should I buy a dongle with SoftAP or should I buy one with Wifi-Direct ? What is the difference between these 2 concepts ? Or is there any difference between them ? Moreover, what chipset (Realtek, Ralink etc) could provide such a functionality ? Which chipset that has this functionality could work happily in a Debian/Ubuntu 32 bit environment ? Thanks in advance for any suggestion.

  • What is "The" book for database design?

    - by FarmBoy
    In programming, there is often a canonical book for a particular topic, like the dragon book for compilers, K&R for C, etc. Is their a book regarding modern database design that simply must be read by anyone that would hope to eventually design databases? I'm not looking for a bunch of recommendations here. The answer I'm looking for is either "Yes, it's [Title, author]." or "No, there are many good books on databases, but no one must-read."

  • Set up heads up for two people

    - by Brian M. Hunt
    Is there a way to set up a Mac or Linux so that one can connect two mice and two keyboards with both users having independent input on the screen with their respective mice and keyboards? I'd like to set up an environment for pairwise programming, and in particular have two developers be able to concurrently edit different documents on the same computer screen, but each person having different keyboards and mice. I'd be much obliged for any input and direction.

  • Linux box acting as wireless access point to share the internet connection

    - by Suresh
    A linux machine is connected to internet over two interfaces ppp0 and ppp1 using two modems. Also this machine acts as wireless access point through an interface say, eth0 with ip address 192.168.1.1 and acts as gateway for the connected devices through this network with subnet mask 255.255.255.0 Now is it possible to achieve the following: When any of the connected devices through wireless AP needs internet connection linux machine has to use ppp1 interface for internet. If any of the applications on the linux machine needs internet connection linux machine should use ppp0 interface for the internet. Can this be achieved by adding rules to chains in filter/nat tables? If the kernel routing table has a default rule to route the default traffic through interface ppp0, wil kernel completely ignore ppp1 for internet? PS: new to networking and routing concepts, If the question is not clear leave a comment, will try to give more information.

  • Agile sysadmin and devops - How to accomplish?

    - by Marco Ramos
    Nowadays, agile systems adminitration and devops are some of the most trending topics regarding systems administration and operations. Both these concepts are mainly focused on bridging the gap between operations/sysadmins and the projects (developers, business, etc). Even if you never heard of the devops concept, I'm sure that this topic is your concern too. So, what tools and techniques do you use to accomplish devops in you companies? I'm particularly interested in topics like change management, continous integration and automatization, but not only. Please share your thoughts. I'm looking forward to read your answers/opinions :)

  • passing URL vars to a wordpress page and pretty-fying it with .htaccess

    - by Jonah
    I have wordpress installed in a directory called welcome, and /welcome/samples is a "page" (created via Wordpress). It's has a php template waiting for a $_REQUEST['category'] When a user goes to /welcome/samples/fun, I want to have "fun" passed to the samples php template in the form welcome/samples/?category=fun But I want the URL to remain in its original form - it's currently replacing the it with the ugly "?cat...etc" # Outside the wordpress block so it won't be overwritten Options +FollowSymlinks RewriteEngine On RewriteRule ^samples/([^/]+)$ /welcome/samples?cat=$1 [R,L] # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /welcome/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /welcome/index.php [L] </IfModule> # END WordPress I tried Rewriting with simply samples?cat=$1 but I was getting a 404. I tried putting in the RewriteBase /welcome/ in the first block. without the [R] flag it doesn't work at all. I keep trying different permutations... and failing:( Perhaps I'm missing some basic concepts... thanks if you take the time to even read through this:) ciao

  • Static Routes and the Routing Table

    - by TheD
    This is very much a learning question if someone would be happy to explain a couple of concepts. My question is - the default routing table that exists in, in my case, a default Windows 7 install, what do each of the routes in the table do? Here is a screenshot: The 10.128.4.0 is just a route I've added while messing. I understand from a question I posted on Superuser the first route is just a default route that will route all traffic for any IP to my default gateway on my Interface in use. But what about the others? And how would the routing table handle a machine with multiple NIC's, perhaps connected to two different networks, or maybe even two NIC's on the same network so a VM can have a physical Network card instead of each VM sharing the hosts. Thanks!

  • How do I "telnet into [my] favourite Web server"?

    - by rookie
    I'm reading a book about programming, and I want to check an HTTP response message. The book is instructing me to telnet into your favorite Web server. Then type in a one-line request message for some object that is housed on the server: for example: telnet cis.poly.edu 80 GET /~hello/ HTTP/1.1 Host: cis.poly.edu What am I supposed to do, exactly? What program do I need? Where do I need to type this message?

  • Why is Flash power-hungry?

    - by Doug
    Apple historically argued that Flash was power-hungry, which made it inappropriate for use on mobile devices. I always thought that was just bluster excusing Apple's exclusion of Flash support from their mobile devices. But now I see that Adobe acknowledges that Flash is a pig. Why is it a pig? Are there bad programming approaches (that can be explained in layman's terms) that make it so power-hungry?

  • Is there a good command-line OS from which I can launch VMs?

    - by Dredj
    Generally speaking, I'm interested in something that can load quickly and, depending on what I want to do, can choose to launch a Virtual Machine that is tailored to my desired activity. So, something that loads to (preferably) a command line, then if I want to run my Windows 7 machine that has all of my programming junk on it, I can simply enter the command to launch some VM player and close it when I'm done.

  • which collaborative tools do you use to communicate between team members

    - by john
    I work for a small company and would like to set up some sort of a collaborative tool so that team members can share thoughts, upload documents...something like sharepoint maybe, but not that suffisticated. Only good option I've seen so far is joomla CMS. Just want to get an opinion of the community on which tools they have used for these purposes. I know this is not programming related but I thought stackoverflow community would be good to get an opinion on this.
