  • Getting started with server and system adminstration

    - by sid__
    I am web developer and I have been doing a lot of server configurations and system administrative tasks lately I was wondering if someone could recommend books and tutorials that would help understand how things are done the right way. Though I mostly work with Apache and Nginx for configuring and maintaining my applications, my approach has been largely trial and error based with information off google and blogs. Could someone recommend books that explain how to get started with system administrative tasks (preferably in a tutorial fashion so that I may try and understand the workings of the system). I work mostly on Linux systems on EC2 Thanks in advance.

  • How do people prove the correctness of Computer Vision methods?

    - by solvingPuzzles
    I'd like to pose a few abstract questions about computer vision research. I haven't quite been able to answer these questions by searching the web and reading papers. How does someone know whether a computer vision algorithm is correct? How do we define "correct" in the context of computer vision? Do formal proofs play a role in understanding the correctness of computer vision algorithms? A bit of background: I'm about to start my PhD in Computer Science. I enjoy designing fast parallel algorithms and proving the correctness of these algorithms. I've also used OpenCV from some class projects, though I don't have much formal training in computer vision. I've been approached by a potential thesis advisor who works on designing faster and more scalable algorithms for computer vision (e.g. fast image segmentation). I'm trying to understand the common practices in solving computer vision problems.

  • Rewrite probabilities as boolean algebra

    - by Magsol
    I'm given three binary random variables: X, Y, and Z. I'm also given the following: P(Z | X) P(Z | Y) P(X) P(Y) I'm then supposed to determine whether or not it is possible to find P(Z | Y, X). I've tried rewriting the solution in the form of Bayes' Theorem and have gotten nowhere. Given that these are boolean random variables, is it possible to rewrite the system in terms of boolean algebra? I understand that the conditionals can be mapped to boolean implications (x -> y, or !x + y), but I'm unsure how this would translate in terms of the overall problem I'm trying to solve. (yes, this is a homework problem, but here I'm much more interested in how to formally solve this problem than what the solution is...I also figured this question would be entirely too simple for MathOverflow)

  • [MINI HOW-TO] Remove a Network Computer from Windows Home Server

    - by Mysticgeek
    One of the cool features of Windows Home Server is the ability to backup and monitor the computers on your network. If you no longer need a machine on to be monitored or backed up, here we show you how to remove it. Remove Computer from WHS The process if straight-forward and basic –Open Windows Home Server Console and click on Computers & Backup. Right-click on the computer that you no longer need and click Remove. You’ll be prompted to verify that you want to remove the machine and delete all of its backup data. Check the box I am sure I want to remove this computer then click the Remove button. That’s all there is to it! The computer and all of its backup data is removed. Remember that if you remove a computer, all of its backup data will be deleted as well. If you no longer have the computer, you probably don’t need the backed up data anyway, but you’ll want to be sure you no longer need it before removing it.

  • How to use batch rendering with an entity component system?

    - by Kiril
    I have an entity component system and a 2D rendering engine. Because I have a lot of repeating sprites (the entities are non-animated, the background is tile based) I would really like to use batch rendering to reduce calls to the drawing routine. What would be the best way to integrate this with an engtity system? I thought about creating and populating the sprite batche every frame update, but that will probably be very slow. A better way would be to add a reference to an entity's quad to the sprite batch at initialization, but that would mean that the entity factory has to be aware of the Rendering System or that the sprite batch has to be a component of some Cache entity. One case violates encapsulation pretty heavily, while the other forces a non-game object entity in the entity system, which I am not sure I like a lot. As for engine, I am using Love2D (Love2D website) and FEZ ( FEZ website) as entity system(so everything is in Lua). I am more interested in a generic pattern of how to properly implement that rather than a language/library specific solution. Thanks in advance!

  • Looking for comprehensive computer monitoring software

    - by cornjuliox
    Summer in this country is insanely hot. So hot in fact, that I think we just lost a machine due to overheating (last recorded CPU/GPU temp was close to 100 C, now it wont start and lets out a long series of short beeps on power up), but that's not my concern here. Since heat is such a problem for me, I use several different pieces of software to monitor temperatures in my machine. I use MSI Afterburner to monitor GPU temp, control GPU fan speed and for some light overclocking, and then I use Speccy and SpeedFan to monitor the rest of the system, CPU temp and everything. The setup works fine for now, but I want to consolidate all this into one program so I'm not juggling several windows at once. Is there any program out there that will let me monitor the following from a single window: CPU Temp and Fan Speed CPU clock GPU Temp and Fan Speed GPU clock, both core and memory Additionally, mobo temp (Speccy lists both CPU and Motherboard temp, I assume that the latter is referring to North and Southbridge temperatures. I'm also looking for the ability to chart these data points on a graph over time, basically to see just how high the temperatures spike under load and for general analysis. It'd be nice if it could handle overclocking of both CPU and GPU in real time too. Any suggestions? Edit: I forgot to mention that I'm on Windows 7, 64-bit

  • What is the biggest weakness of students graduating with degrees in Computer Science?

    - by akobre01
    This question is directed more toward employers and graduate student advisors/professors but all opinions are welcome. What do you find is a common weakness of new hires and/or new grad students? Is it entirely variable dependent on the student and his or her university? Is there a particular skill or skillset that you wish new hires/researchers had expertise in and how can we remedey this deficiency? I realize that this question is general and really encapsulates two questions, one more about the weaknesses of new software engineers and one about the weaknesses of new researchers. However, both types of people tend to come from similar courses of study so I'm wondering if there is any overlap. Note: I am not a professor but I'm interested in how best to revise the undergraduate curriculum in CS.

  • Copy Ubuntu distro with all settings from one computer to a different one

    - by theFisher86
    I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out. On the source computer run dpkg --get-selections > installed-software and backup the installed-software file Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory. Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/ Then I'm going to run dpkg --set-selections < installed-software Followed by dselect That should install all of my apps for me. I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here. I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...

  • Home entertainment karaoke system

    - by Mehper C. Palavuzlar
    Here is what I have: 40" Sony Bravia LCD TV, 5+1 speaker system, lots of original Karaoke CDs, and of course, a microphone. To set up a karaoke entertainment system, what kind of hardware do I need? Are there any standalone karaoke players out there? I hope my only option is not having to connect my laptop to TV. I already have karaoke software on my laptop but I wanna step up to a higher level without the help of a computer.

  • Permanently hide network disconnected icon from system tray

    - by Steve
    On Windows XP, I have a disconnected Wireless connection which shows up in the System Tray. I have gone into Network Connections dialog box and elected not to show an icon when it is disconnected, yet it remains visible. I have gone into the Task bar properties and elected to always hide this icon, but that doesn't remove it from the system tray. How do I remove it? Thanks

  • Running SEP scans with the SYSTEM account

    - by Eric
    I need to run Symantec Endpoint Protection scans on Windows 7 systems using the SYSTEM account. I know that I can run DoScan.exe to manually run a scan, and this works fine using a regular user account. Unfortunately, when I try to run DoScan as SYSTEM, the application exits immediately without running a scan. Is there a way that I can get this to work, or another application besides DoScan.exe that I should be using?

  • System files not hidden Win XP

    - by ULTRA_POROV
    I recently copied my win xp install from one hard to another(via ubuntu live cd) Everything went well, except that all the hidden system files(boot.ini, ntdlr, io.sys) are no longer hidden. I tried this: attrib +s c:/IO.sys No effect. The files are still visible even though the setting to hide system files is checked. Any solutions? Thanks.

  • Dissect System Restore snapshots

    - by Unsigned
    Is there any way to map the A000????.??? filenames in the System Volume Information to their original names, without restoring them? The reason I ask is that several files in one user's System Volume Information RP1 were infected by a rootkit. Although they've been removed, I'd like to be able to figure out what they were originally. A0001253.sys and A0001211.sys are not very helpful names. :) It happened on two systems, one XP SP2, the other XP SP3.

  • Why is 'System' process at 100%?

    - by ripper234
    On Windows 7, the 'system' process is taking up 100% CPU (well 50% on a duel core) for a rather long time. Its CPU usage doesn't seem to drop at all. How can I diagnose this problem? What could be the cause? I don't see any other problems with the system and am using an up-to-date AVG, so I don't yet suspect a maelware.
