  • My Mac is slow but don't know what's slowing it down

    - by duality_
    My Mac (Macbook Pro) is sometimes slow doing basic tasks, like browsing the web or something like that. If I open Activity Monitor, I have (maybe) one program that is about 10 % CPU, others are below 1 %. My CPU usage is not full. I still have more than 2 GB of free memory (out of 5 GB). There is no heavy I/O activity like copying files. My open programs are Google Chrome (6 tabs, none of which are in some way (flash, many DOM objects, Javascript) have IMO, except maybe Gmail), Activity Monitor, Finder, Sublime Text 2 (text editor) and iTerm (terminal). What is causing the slowdown? "Slow" being: taking time to write these characters (I press the keyboard keys but there is a delay before I see them on the screen), changing tabs or programs, etc.

  • How to reconnect to Remote Session in a script?

    - by Lukasz
    Hello, I need to persist a Remote desktop connection across a reboot of a Terminal server. I'm thinking that it would be something like a scheduled task that would run periodically and check the running state of the session and restart it if it's down. BTW, I did check the "Reconnect..." checkbox on the advanced tab of the connection options, but it still goes down everytime we restart the terminal server. Does anyone have the script that would accomplish the above in a scheduled task, or perhaps another solution?

  • Rewrite URL based off of IP on OpenWRT

    - by Scott
    We are running OpenWRT on a WRT54GL. I have been looking for an answer to this, but I can't seem to figure out what to search for, if its possible, or what combination of programs to use. I want to be able to redirect a HTTP request from a WiFi device based off of their MAC address. This should all be transparent to the device. Basically we are trying to redirect any non-registered devices to a website to register the device (at this point, we would push a new config to the router that would allow this MAC address "full access"). Once a device is registered, it will be redirected to a transparent squid proxy server on another machine for caching/blocking certain sites. I looked at tinyproxy - popilo which redirects but I won't have the MAC address to know if its registered or not. Any help (google suggestions, programs, anything!) would be very much appreciated!

  • Does it actually matter whether you have open applications when installing new software?

    - by Dan
    It seems the norm these days is for installers/setup programs to request that you close all open applications before initiating the install process for a piece of new software. I used to obediently follow these directions without fail, even though it could sometimes be frustrating having to close open documents and stop working on things just to get a new, seemingly unrelated application installed. Then at some point I simply stopped bothering. Nowadays if I have a lot of stuff going on I might even run multiple installers at the same time; I can't even recall a time it has ever posed a problem. Why do setup programs even make this request in the first place, then, when it appears to be unnecessary? Is this just to simplify troubleshooting for companies' support people? Has anyone else ever run into problems as a result of trying to install an app while other apps were open?

  • Supervisor VS cronjob

    - by Guandalino
    Actually I'm using supervisor to monitor a process and restart it when it stops for some reason. The problem is that in case of a supervisor crash the process stops get monitored. So I thought to schedule a cronjob to check supervisor is running, and eventually restart it. The next thing I'm considering is to get rid of supervisor and check my process directly from the cronjob. I read that sometimes supervisor uses too much memory (to be verified, though). What are the pros in having supervisor VS cronjob monitoring the process?

  • Notepad Automatically Launches Upon Boot Up of my Windows 7 64-Bit Desktop PC

    - by Simon
    Around 12 months ago, When my Windows 7 PC boots up, Notepad started to appear automatically on the desktop (as a duplicate ie one on top of the other), both displaying the same writing inside, and the name of the Notepad was: desktop-Notepad. [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787 I cant remember the exact details as its been so long now but a friend told me, this was due to a "hidden attribute" belonging to notepad becoming "unhidden"and therefore showing itself on the desktop at startup. He showed me a series of steps to either hide the attribute again or to delete it ( telling me that upon restart of my computer it would be recreated/regenerated.) I did indeed follow his guidance however after trying to hide it or delete it (it was never recreated after restart which supposedly it should have done) One notepad still is autolaunched with the text as shown above everytime I startup my PC. As I found this forum I thought I might try again for a solution to prevent notepad from launching. Thankyou

  • Munin "Available entropy" when using address space layout randomization

    - by clawspoon
    Having just configured Munin for statistics logging on my gentoo server (hardened profile), I am noticing that my "Available entropy" is consitently in the 200-300 range. This seems way to low, so I checked it manually using the command $ cat /proc/sys/kernel/random/entropy_avail 3544 Odd. Consistently very low values in Munin and practically filled up when checking manually. After thinking about the problem for a while I came to the conclusion that the problem is probably that I'm using Adress Space Layout Randomization which is using the entropy when running commands/programs. Since Munin runs a whole slew of programs all the entropy is used up, and Munin then measures how much entropy there is, resulting in the low values. Does anyone have any experience with this? How can this be avoided?

  • Links won't open in Outlook

    - by Scott Mitchell
    About a week ago Chrome (my default browser) stopped working and I ended up reinstalling. After that, however, links in Outlook 2007, when clicked, no longer open. Instead, I get a warning that reads: General failure. The URL was: URL. Application not found. I presume that there is some MIME or file type association that needs to be configured at the OS level, but I've not had any luck so far. My operating system is Windows 7. Any ideas? EDIT #1 Wayne Johnston suggested I set Chrome as my default browser, but when I go to the Set Default Programs screen in Windows 7 (via Control Panel) I do not see Chrome in the list of programs. How do I get it to show up there?

  • OS X mavericks latex issue

    - by Vineet Bafna
    I upgraded to Mavericks and found that pdflatex stopped working. I followed some previous discussions to recreate a link that Mavericks had broken. sudo ln -fs /Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin texbin The error message changed to "Permission denied". I tried to change permissions, but it does not work.

  • Chromium always starts as floating in awesome.wm

    - by xhochy
    I'm using awesome as window manager for a small surf&info terminal. Chromium is started directly after login on the first workspace and should be displayed fullscreen. I've set the layout of all workspaces to awful.layout.suit.max and followed Awesome FAQ so that Chromium and all other (automatically) started programs will be shown on the right workspace. All programs except Chromium will start correctly in fullscreen mode. I tried { rule = { class = "chromium-browser" }, properties = {floating = false, tag = tags[1][1]}} and { rule = { class = "chromium-browser" }, properties = {tag = tags[1][1]}} but Chromium will always start in floating mode. This is a bit annoying as you still see awesome's panel at the top.

  • What program is making this sound and how can I make it stop

    - by DrFredEdison
    Some program is intermittently making this weird "chook ... chick" sound, no more than every 5 minutes, but sometimes hours or days between making it. There seems to be no pattern as to when it happens, but the sound is definitely coming from the speakers, and is always the same, so I'm pretty confident some piece of software I'm running is playing the sound. Today, I managed to record it, and I've posted it here: http://tristanhavelick.com/chook-chick.mp3 Short of closing my programs one by one, and seeing if the sound continues, are there any tricks for tracking down a problem like this? Is there any software that can trace what sounds come from what programs (something like tcpview with waveforms)? I am running windows xp.

  • How to reset video/display drivers in Vista without restarting OS?

    - by jdk
    Currently I have to reboot my system if an external monitor is hooked up for it to be correctly detected and used. I think it would be faster to restart/reset the video or display drivers instead. How do I do this under Vista? I seem to remember from an old laptop using a Windows command-line command that would restart the wireless networking card device when it crashed. Is there something like that for video drivers? Background/Reason Because people rightfully ask why? - This is part of a larger problem which I'm waiting for resolution on from the manufacturer. In the meantime I'm looking for the above quick fix. Actually my video card often crashes my laptop when attaching an external monitor and trying to detect or use it. No solution from vendor yet and latest drivers do the same irksome behaviour. Windows says: A problem with your video hardware caused Windows to stop working correctly.

  • Is there a way to delay a forced reboot?

    - by jduff
    I realize this is more appropriate for our company's admin group to field. However, pretend they are unresponsive just for the sake of discussion =) If my system is prompting me to reboot now or in a set time (say in 15 mins) is there a way to delay that even further? It is usually just an inconvenient time and I would like to delay beyond the stated time. (ex) System Restart Required: A newly installed program requires this computer to be restarted. Please save your work and restart your computer. Your computer will automatically be restarted in: xxmins... Thanks for any responses in advance!

  • push_back of STL list got bad performance?

  • Win 2k3 server's network problem.

    - by Sam
    I'm running 4 of Win2k3 64bit servers in the same subnet. It's been more than an year that I've running them without a problem. Recently, I kept losing the connection to one of the server. Let's say it's 'server A' which has a problem. Losing the connection means that I can't access to server A from the other servers. I've checked if server A has any internet connection problems or are there any abnomal event logs in the eventvwr - but haven't found any problems. The problem usually resolved if I restart the server again. But as time goes by, it keeps happen again and again. I can't afford to restart the server every time, and I really want to find out the reason. Can anyone help me out? Let me know if you guys need any of more information.

  • Incremental backup up from a remote ftp box to a Windows server

    - by user65712
    I need to backup a website to a Windows server every week and I only have access to remote FTP. I'd like to use an incremental backup program so that I can just copy the files every week on a schedule and not worry too much about the size of the backups becoming an issue. Unfortunately, I can't find a Windows program that will automatically make incremental backups of specific FTP folders and files, as most programs are designed to backup to FTP, not from it. Are there any applications that can do this? I also have a Ubuntu 10.04 box I could use to relay the site to the Windows server if I needed to run Linux programs, but I would prefer a Windows-only solution over a Linux/Windows one, and a combined Linux/Windows solution over not having it work at all.

  • Windows system drive letter changed after repair install

    - by taffer
    yesterday I did a repair install, because Windows froze on welcome screen after resizing its partition on a dual boot system. corresponding question Everything worked fine so far, but now I am facing another challenge: The Windows drive letter changed from G: to C:, so that most programs, including drivers, firewall and virus scanner do not work anymore. I tried to reinstall the virus scanner, but the uninstaller said, that drive G: is not available. What to do now, to get all programs running again? Is it possible, to rename C: to G: or will that mess up my system?

  • Using FastCGI for PHP on Mac OS X

    - by DanieL
    I have apache2 running on a Mac OS X (10.6) machine, and it is currently serving PHP pages fine, using php5_module but I would like to configure fastcgi_module to handle the php pages. I have tried using the configuration found on www.fastcgi.com but I get the following error: [warn] FastCGI: (dynamic) server "/Path/to/script.php" has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 600 seconds [warn] FastCGI: server "/usr/bin/php" has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 600 seconds I'm thinking this is because PHP has not been compiled with FastCGI, but seeing as it came with Mac OS X i'm not sure how to recompile it. Is this the problem? And if so, how do I recompile PHP with FastCGI?

  • Computer experiencing slowdowns and lockups despite low cpu useage

    - by user157145
    my setup i5-2300 nvidia gtx 550 ti 6 gigs ram 600 w ocz modular psu recently reformatted and already experiencing drastic slowdown as soon as windows comes up, including repeated lockups with multiple various programs reporting that they are not responsive, then recovering after 10-30 seconds. ive checked memory and hard drive both of which come out fine. despite my plethura of worthless antiviral software im forced to assume that my illicit downloading practices have lead me into some comp trouble that i cant seem to determine. i have used ccleaner, search and destroy and malware bytes, all of which have found nothing to indicate what is causing this massive slowdown. in addition according to my resource manager my computer is operating at a load of only 30-50 percent CPU useage and 60 ram useage but taking 5-10 seconds to load files and open folders, and repeated lockups of multiple programs, especially firefox which seems to go unresponsive every 2-3 minutes. any help would be appreciated, i used a program called OTL by old timer, but cant make any sense of the results i was given. any help or suggestions would be appreciated, thank you for taking the time to read this i have avast but it didnt even find anything when i had it do a full system scan, so im thinking its clueless(also nortons, avg, and ad-aware). i also have mse but it has yet to complete a full scan it takes so long (i left it on last night but when i woke up my computer had a problem and had to restart). my hard drive has 300 gigs out of 1tb open and i already used hd tune pro, which said my harddrive was fine and its not a ssd. also im a noob at comps and only have the hd that is currently inside the computer in addition im not sure if studdering is the issue im suffering. my problem is that during my typing of these responses firefox has gone "not responsive" at least 5 times, each for times of about 5-10 seconds. when i try to control alt delete to bring up windows task manager it took 20 seconds. essentially its that my computer goes super slow at bringing up anything, or taking any action whatsoever that opens a program or file and has repeated incidents where i cant even click on whatever im trying to do because it locks up. the confusing thing about these incidents is that its right after restarting where there are minimal programs running and the computer and memory load is light.

  • Audio services in windows 7

    - by infant programmer 'Aravind'
    In an attempt of blocking a viral service on my system (which was restarting my system automatically for every 30 seconds), I disabled all the services, and later enabled trustworthy services only. (note: Hide all microsoft services didn't work blocking the auto restart so I disabled all services) Now I have been succeeded in blocking automatic restart and I am able to access internet and all other necessary stuffs. Well, however system audio is mute(definitely because a necessary service is not running). Now I need a list of services that need to be started (set automatic) on windows 7.
