  • How can I reduce the CPU usage of Offline Files?

    - by Diego
    Whenever I have the Offline Files service running, there is a constant 25% CPU usage on svchost.exe (this is a quad core, so that means it's using up one core). This, in turn, triples the power consumption and keeps the machine hot... I do have several GB synchronized (music collection), but they are not changing at all, in either side. Am I misusing this feature? Is there anything I can configure to keep it down when there's nothing to do? Or should I forget about it and synchronize big folders manually?

  • Will I have internet connection issues next day, if I unplug router at night?

    - by headskracher77
    I did this regularly a few years ago and used to feel like I was 'being punished' by the Interent svc provider for disabling access to my computer, because trying to re-connect the next day became a constant pain. I have the same linksys router, a comcast modem, and hi-speed broadband through their LAN. Question: who or what is at fault for lousy internet connections, slow connections, or no connections: (everybody's tech dept. blames everybody else) The router? 10 year olds, maybe obsolete? The modem? came with the service plan - can connect three devices on a sharedconnection. The ISP: I read they not only even control and completely regulate bandwidth usage, but they also ration it!! (true?) So can I safely 'pull the plug' each night for security or not? thnx

  • Why doesn't my laptop battery charge while the laptop is in use?

    - by larryb82
    Up until a week ago, my laptop has always been able to charge the battery while I'm using it. Now, it will not charge unless the computer is sleeping, hibernating, or turned off. The icon in the start tray states that the battery is charging but it is not animated (it used to be) and of course the power level does not increase. Otherwise, the battery seems to be fine. The battery life is decent (2h+) and while the laptop is in use and plugged in the battery will maintain a constant charge. Any troubleshooting help would be great (i.e. is this a charger issue, battery issues, software issue, etc...)

  • Check if current Command Prompt was launched as the Administrator

    - by Canadian Luke
    I am looking to write a script that takes user input, then makes system wide changes. I need this to be very generic, but simply put, at the top, I need it to check to see if it's being run 'As an Administrator'. If it's not, then I want to display a message to tell them that; if it is, I want it to continue on. Is there a constant way to verify this? I am not looking to start a new session as the Administrator, I just want to detect if it's currently run as admin

  • Windows7 issue in mutli- tasking and memory

    - by Nitesh
    I seeming some problem in my windows OS recently, let me first say my system configuration. processor - Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66 GHz Installed memory (RAM) - 4.00 GB (3.00 GB usable) System type - 32 bit operating system I am using two OS in this system, first one is Windows7 and the other is centOS. Well, I am using this from a long time there was no problem , and all of a sudden since from couple weeks I am facing problems in my Windows7 OS. In windows7 i was nearing using multiple jobs almost every time i log in, there was no problem but now i don't no what happen I am not able to do multiple jobs at same time. For example- 1 I am now not able to listen to music in windows media player and view photo's. All of a sudden the system stops working and does not respond and then respond after 5mins and the music get played where it got stopped after 5 mins. 2 When i start browersing internet it hangs all of sudden and doesn't respond for 2 or 3 mins and gets loading. I mean it just happens for every operation i do in the system. Even now typing was also difficult, it gets hanged very frequently even though i am doing single task. I have never come across this kind of problem before. So the first thing i did was to see the useage of the processor and the memory. Well, i thick the useage of the processor was fine, for single task the useage was some where around 3 to 5%. Well, it was something weird i found in the memory, in spite of no task that i was running it was using somewhere around 34 to 41% of memory. So i opened the task manager and click on resource monitor in performance tab. And in the memory section of the monitoring tool i found the usage of my RAM, it was something like this. Hardware reserved - 1029 MB In Use - 1430 MB Modified - 49 MB Standby - 1566 MB free - 22 MB And i could also see Available 1588 MB Cached 1615 MB Total 3067 MB Installed 4096 MB well, this if all i could find out and i have no idea why my computer is acting so weird all of a sudden and the performance problem is growing day by day and i also don't know if there is problem in Bios, i have let it for default settings from long time. please help me and Thank you in advance for reading this and helping me.

  • What free OS should I use on my VPS?

    - by earlz
    Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

  • Prevent Concurrent File Changes: Windows Server 2003

    - by ThinkBohemian
    I have a program installed that writes configurations to disk installed on Windows Server 2003. When two administrators log into the machine at the same time, the last admin to save will persist their configurations, while the first admin's saves will be lost. Is there any way I can restrict access to a only this program so that only one person can edit it at a time? If not, is it possible to restrict user access to only one program?

  • Is it possible to get a list of running processes with a Cloudwatch Alarm?

    - by jtalarico
    We have an EC2 instance (Ubuntu) that has a few java-based applications and lately we're getting hit with high CPU utilization spikes that trigger one of our Cloudwatch alarms. By the time we get into the server to look at the cpu utilization, things have calmed down. What we'd love to see in one of the alarm emails is a list of running processes and their cpu utilization(%) at the time of the alarm. Is this even possible?

  • Professional graphics cards a "must" for rendering static environments?

    - by Imhotep
    I'm not sure if the title is clear but with more words what I want to say is: I'm building a PC for a decorator who's main work is to render photorealistic images of house interiors. For that she uses 3dsMax and AutoCAD with Accurender and Photoshop. Is there a need for professional graphics card like Quadro series or FireGL series? Do these cards offer any improvements on rendering time or are they only used for real time rendering?

  • Looking for personal scheduling software / todo list with rather particular requirements

    - by Cthulhu
    I've been scouring the web for a couple of (my boss') hours, looking for a piece of software that can organize my tasks in two ways. First, I have a list of bullet points / todo items I can do at any given time. Think of stuff like solve issue X, ask X about Y, write documentation about Z, etcetera. Second, I have a number of running projects I'd like to organize better, as in schedule for a certain part of a day of the week. Ideally (I think), my day would be organized as 50% spent on projects and 50% on the other small things. Now, I don't like most calendar applications (such as Outlook & friends), their UI is too 'official', not really easy to move stuff around (in my experience). I don't like most todo lists either, too static and things. I like new, fast and hip software. I've looked at GTD versions of Tiddlywiki, and I like mGSD for one particular feature. You can make lists of tasks and basically give them one of three statusses - Now (nothing required, you can do it right away), Waiting (you need someone or something before you can work on this), or the most gratifying of all, Done. I like that feature because it's a simple todo list, but indicates more accurately the things you can do right now and the things you depend on someone else for to do. Anyways, that's just a small aspect of that program - most of the other things in there I can't find a particularly good use for. If there's something like that (maybe something that works even snappier, cleaner UI), combined with an easy to use bit of scheduling software (optionally separated into two applications, but preferrably not), I think I'd like that. (Besides something like that, I also use several instances of Trac to monitor tasks and bugs and things for the various clients and projects I have to serve, and TaskCoach to monitor the amount of time I spend on each task / each client. An easy / low-maintenance time tracking software would be neat too) Of course, the software has to be free to use. I don't like shareware, trials, limited software and the like. I could develop my own too, but I'm lazy like that and there's a dozen other projects I'd like to do in my free time (neither of which I actually do). Edit: I like David Seah's printable CEO stuff, if something like that (with some video game / instant achievement / gratification) exists in software, it'd be awesome.

  • Rsync and Lazy mode ?

    - by fabien-barbier
    Since transferring or copying a file that is being used sometimes causes corruption of the transferred file, can we define a time interval in which Rsync checks each file in a given directory to see if there is a change within that time interval ? Files that are not changed during that interval will be transferred, while those that have changes will not. Can I do that with rsync ? Or another tool ? Is there a script to add this functionality to Rsync ? Thanks

  • How do laptop battery voltages affect runtime?

    - by Bigbio2002
    I ordered a new battery for my faithful XPS M1710. I'm not sure of the voltage of the battery I have now, but the new one that the Dell rep got me (after 3-4 times confirming my phone number and laptop model number) is 14.8v. I was a bit concerned about potential incompatibilities (as most of the other compatible batteries listed were 11.1v), but I figure that there's no way that Dell would "recommend" batteries that wouldn't work or fry your system. Now, my question is, how does voltage affect battery life? If we assume the needed power draw to be constant, a higher voltage would indicate less amperage needed, therefore the battery would last longer before running out, yes? Or am I missing something? For reference: P=I*V P = power I = current V = voltage (duh)

  • How do I make a backup of a live server?

    - by Jurily
    At my new job, I have a production server with the following qualities: Windows (XP I think), ancient hardware Absolutely vital database No backups whatsoever Everyone in the company has full admin rights, the passwords are stored in a .txt on the global share No installers, except for the OS The machine itself is sitting on a wooden shelf 5 feet above the ground against an external wall with frequent truck traffic on the other side; the shelf is already bent from the constant load Hasn't been rebooted in $DEITY knows how long, my predecessor wasn't even sure if it would survive it UPS is installed, but since everything is hooked up to it, it would last 10 minutes tops No spare parts or hardware budget How do I make a full backup with minimal impact on the server? I'm not sure how close it is to a total meltdown. For all I know, plugging in a USB stick could kill the company, and of course it will be all my fault, since "it was running fine before you touched it". The ideal solution would be a VM, so I have a test environment as well (separate of course).

  • How to implement a secure authentication over HTTP?

    - by Zagorax
    I know that we have HTTPS, but I would like to know if there's an algorithm/approach/strategy that grants a reasonable security level without using SSL. I have read many solution on the internet. Most of them are based on adding some time metadata to the hashes, but it needs that both server and client has the time set equal. Moreover, it seems to me that none of this solution could prevent a man in the middle attack.

  • "I'm Feeling Lucky"-style behavior in Windows 8.1 search?

    - by vorou
    Is it possible to make Windows 8.1 automatically select the most relevant search result, so that I could just press Enter to execute it? Right now, I have to press down-arrow each time to select it, and then press Enter. I occasionally forget to press the down-arrow, and Windows opens that very useful Search Results window for me. It makes me sad since I'm absolutelly happy with the top search result nearly all the time. P.S.: I'm taking about the Search in Start menu (the menu which opens when I press winkey)

  • Determining which database instance makes biggest IO

    - by user2008937
    Assuming that I have a dedicated server on which I am running multiple instances of mysql and postresql servers. How without iotop determine which instance in particular time (proc/pid/io shows data collected in some peroid of time) makes the biggest IO (so it increases IOWAIT)? When lots of ppl do something on DB then I clearly see which instance is making the load because of high cpu usage, but I had a situation when the cpu usage was just normal, but very high iowait made a huge load on server and i had problem finding process that was making some outstanding IO

  • How to calculate required switch speed based on network usage?

    - by tobefound
    I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

  • unstable / variating sound level (volume) within same song / clip

    - by Bastien
    Hello, I have a pretty standard Acer desktop (I guess a predecessor of the X5900 model). when playing mp3 / radio / youtube clips, the sound level is changing WITHIN the clip, highly annoying. in the case of an mp3, the same mp3 will play at a constant sound level on my iPod, so clearly an issue with the computer. problem existed under vista, I upgraded to windows 7 and have the same issue. I guess it might be soundcard-related, so updated the drivers, no luck neither. any idea ? thanks
