  • How to set up a server without a hosting control panel

    - by A4J
    I have always used a control panel on my dedicated servers - from cPanel to Plesk to Virtualmin, and I am now considering ditching a CP altogether and manually editing config files. My requirements are fairly simple, I will host multiple sites on the server; some Apache with PHP & Mysql and some Passenger with Rails & Postgres. All will require email smtp/pop. FTP/Stats will not be required. Could someone please give me a quick run-down of what I would need to do - in terms of installing software and configuration? My server will come with a base install of CentOS 6.4 minimal. My thoughts so far: Install/update latest versions of MySQL & Postgres (are they 'safe' out of the box? Or do I need to do anything else like set up root passwords etc?) Install Apache & PHP (again, are the base installs good to go or do they require security tweaks?) Set up nameservers/hostnames/reverse DNS etc (Any guides on how to do this please?) Install Rubygems Install and configure Dovecot and Postfix (any tips on doing this? Or links to how-tos that cover it please?) Set up each website - any links to guides on how to do this? Install/configure firewall (or is the default install good to go?) Any other tips or advice would be greatly appreciated, as would links to guides or how-tos.

  • Windows 7, how to get unlock (Press Ctrl+Alt+del) prompt on all monitors?

    - by Zugwalt
    I have a laptop that I keep shut in a docking station as I have two screens connected to the laptop and it cannot display to both of those AND its own screen. However, when my computer locks by itself (Not when I lock it using Ctrl+Alt+Del) the login prompt is ONLY on it screen (at least its there when I open it up) and my primary external monitor is off and my other one is all black. This means to log in I have to hit Ctrl+Alt+Del and blindly enter my password--which I don't mind too much, but would prefer if I could actually see the unlock/login prompt instead of typing on a black screen. Any way to have it show the login prompt on all monitors?

  • How to write a real time data acquisition program [closed]

    - by Tosin Awe
    I have to write a program in assembly language that will monitor temperature continuously, and I have no idea where to begin. The temperature must be displayed in BCD format, and the high and low set points will be programmed into the system. if the set points are exceeded then an alarm will be indicated. The low point is 20 degrees Celsius, and the high point is 24 degrees Celsius. Can somebody give me some hints on how to complete this task?

  • Settings object with singleton pattern

    - by axis
    I need to build an object that will have only one instance because this Object is dedicated to the storage of vital settings for my application and I would like to avoid a misuse of this type or a conflict at run-time. The most popular solution for this, according to the internet, is the Singleton pattern. But I would like to know about other ideas or solutions for this; also I would like to know if other solutions can be much more easy to grasp for an user of this hypothetical library. Thanks.

  • Storing translation data as JSON column

    - by j0ntech
    We're deciding on how to store translations of some descriptions of database items. We could go the traditional way and keep a translations table (and a language table and an object_translation linking table) OR we thought it might be better to just have a Description column that contains JSON like the following: { "EN": "This is the translation in English", "EE" : "See on kirjeldus eesti keeles" } Are there any serious downsides as to why we shouldn't use this? (I haven't seen it being used anywhere else)

  • Replicating A Volume Of Large Data via Transactional Replication

    During weekend maintenance, members of the support team executed an UPDATE statement against the database on the OLTP Server. This database was a part of Transactional Replication, and once the UPDATE statement was executed the Replication procedure came to a halt with an error message. Satnam Singh decided to work on this case and try to find an efficient solution to rebuild the procedure without significant downtime.

  • Single space on secondary display?

    - by zoul
    Hello! Is it possible to only have one space on secondary display when using Spaces on Mac? I’d like to have three spaces on the primary display and only use the secondary one as a common “sideboard” that does not change when I switch Spaces on the primary display.

  • Free Hosting control panel

    - by John Maxim
    Hello All, I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server? I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ? Something more organic? which doesn't require much breaking and changing. I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me. And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus. Thanks in advance.

  • A separate solution for types, etc?

    - by hayer
    I'm currently in progress updating some engine-code(which does not work, so it is more like creating a engine). I've decided to swap over to SFML(instead of my own crappy renderer, window manager, and audio), Box2d(since I need physics, but have none), and some small utils I've built myself. The problem is that each of the project mentioned over use different types for things like Vector2, etc. So to the question; Is it a good idea to replace box2d and SFML vectors with my own vector class? (Which is one of my better implementations) My idea then was to have a seperate .lib with all my classes that should be shared between all the projects in the solution.

  • Why do people like widescreen when it is, de facto, less space?

    - by Kerry
    I find that many of my friends/non-programmers or designers like widescreens. It makes very little sense to me as you in fact have less space than a 4:3 (do the math). The closer to a perfect square the more space you actually have on your screen. I got a 21" 16:9 and two 19" 4:3 The 21" is nearly the same height, but I think its a tenth of an inch shorter if I'm correct. I forget the calculation but it is nearly the same actual space. I can understand if you're using your computer for constant movie-watching but I think that's more of people's "ideal" than a reality. Thoughts?

  • Find rows that match multiple (two) criteria

    - by Scott Sanders
    I am trying to get a list of items that match on two criteria. DATE PRODUCT CHANNEL DEC 13 Cat Chow DRUG NOV 13 Pupperoni DRUG DEC 13 Meow Mix DRUG DEC 13 Jerky Treats DRUG This is the data from A1 to C5. I want all the product sold on DEC 13 and in the DRUG channel. This is the formula that I have now, which is only bringing back the first example. INDEX($B$2:$B$5, MATCH(1, ("DRUG"=$C$2:$C$5)*("DEC 13"=$A$2:$A$5), 0) )

  • 3 Monitors on GTX 460 and P7H55-PRO

    - by Ahren
    I have a dual monitor setup on my GTX 460. I'd like to use the integrated graphics combo of my P7H55-PRO + I3 550 to display a 3rd monitor. This won't be used for gaming, just for more work space. Is it possible? The integrated display adapter won't show up in the device manager at all. The monitor is plugged in and powered, and working, but doesn't show up in display settings. OS = Windows 7 64bit RAM = 8GB

  • What's a good way to store a series of interconnected pipe and tank objects?

    - by mars
    I am working on a puzzle game with a 6 by 6 grid of storage tanks that are connected to up to 4 tanks adjacent to them via pipes. The gameplay is concerned with combining what's in a tank with an adjacent tank via the pipe than interconnects them. Right now I store the tanks in a 6x6 array, vertical pipes in a 5x6 array, and horizontal pipes in a 6x5 array. Each tank has a reference to the object that contains both tanks and pipes and when a pipe needs to be animated filling with liquid, the selected tank just calls a method on the container object telling it to animate the pipes it is connected to (subtract 1 from row or column to find connected pipes). This feels like the wrong way of doing it, as I've also considered just giving each tank references to the pipes connected to it to access directly.

  • Can Apache be configured to specify more than one docroot per virtualhost?

    - by syn4k
    I have a vhost which specifies <VirtualHost *:80> DocumentRoot "/private/var/www/html/cms/sites/" ServerName localhost.com </VirtualHost> I would like to know if localhost.com can also point to /private/var/www/html/wordpress/. This seems like a no brainer but Apache is like black magic; these things are always possible. Anyway, I already know that I could specify a new ServerName entry and set a new docroot. The problem is, both directories need to be available as roots. If I need to provide more info, I will gladly do so.

  • Setting up a copy of a site with IIS 7?

    - by SJaguar13
    I have a site running on IIS with a dyndns.org domain that points to the IP of the Windows 2008 machine hosting it. I need a copy of that site for development purposes. I set up another folder with all the files, and create a new site in IIS. I don't really have a domain for it, so I was just going to use the IP address. When I go to localhost, 127.0.0.1, or the internal IP, I get bad hostname. If I use the IP address on port 80 (the same as the real version of the site), I get 404 not found. If I use a different port so I don't have them both on the same IP with the same port, I get connection timed out. How do I go about setting this up?

  • Windows 8.1 erased Ubuntu 14.04 partition

    - by Caumons
    I had Ubuntu 14.04 installed with a Windows 7 dual boot. Now, I've just replaced W7 by Windows 8, but the Ubuntu partition has disappeared! Running fdisk -l doesn't show /dev/sda5 (which was the Ubuntu partition), if I access to Gparted, it shows the Ubuntu partition as "empty space" and from Windows 8's device manager, this partition also appears as empty space! WTF has happened here? Has the partition been actually erased?

  • Suitable companion monitors for HP LP3065 30" primary monitor

    - by Bittercoder
    I have an HP LP3065 30" monitor - now I want to add a couple of companion screens to either side of it - I've heard to people suggesting 21" monitors in portrait mode - but it seems difficult to find a suitable panel these day, as 22" wide-screen monitors have become common, and I can't seem to find anything with a suitable 1600 pixel width. Can anyone recommend a suitable monitor, and suggest what criteria are best for picking a suitable monitor - what's important to consider - I'm thinking things like: Exact resolution match? Viewing angle? Small/thin bezel?
