  • My CPU hits 100°C... Help me!

    - by JamesT
    The safe limit for processors is typically 50°C or so, but I have found that my CPU likes to do up to 100°C. I have got these readings from SpeedFan 4.42. I have a Intel Quad Core unclocked. I am using the standard intel fan with heatsink that came with the prossesor My case is a Cooler Master and I have two fans installed on the case. I took the side off to see if that helped. It lowered the temp be 3C. I don't really want to blow the processor and I don't know how to cool it down.

  • Is it possible to restrict the connection duration per client on the router (say with OpenWRT)?

    - by static
    How to limit the connection duration per client per period (say, one MAC-address can connect only for 3 hours per week to the network). Where could be defined such a rule? In the firewall? So the rule should define not statically times (this is simple), when the client is allowed to access the network, but the duration of the connection per day/week/month, etc. How/where to implement such rules? Is it possible to do so with OpenWRT/DD-WRT?

  • Does "..." have meaning as a relative pathname? (EDIT: No.)

    - by Pup
    1. Is there a relative pathname/directory/folder meaning for the expression "..."? 2. What does "..." refer to in the context cited? I encountered the expression "..." when looking at the installation instructions for http://code.google.com/p/vim-win3264/wiki/Win64Binaries and it says the following (note bolded text): Unzip the zipfile into a directory whose name ends in vim, such as C:\Program Files\Vim, D:\vim, or C:\mytools\vim. This will create a vim72 subdirectory, containing all the files. Start a cmd.exe window, cd ...\vim\vim72, then run install.exe, the command-line installer. This will offer you a series of choices. You can probably just type d to "do it".`                                               Bonus points for listing all relative directory pathnames!

  • How to know or change the size of the Windows Event Log from a program under Windows XP? [closed]

    - by ahmd1
    I ran into a weird problem on a Windows XP system. My local service app logs its diagnostic messages into the Windows Event Log, so at some point those messages stopped being logged. I thought that the issue was in my code, but then I discovered that other processes can't log messages either. So I was wondering, is there a limit on the Windows Event Log size? PS. I guess I need to write this specifically -- I need to know/change the size from a command line or an API.

  • How can I set up disk quotas on a remote server in a Samba environment?

    - by graf_ignotiev
    I've been working with an install of Ubuntu 8.04 and Samba. I'm trying to set up user disk space quotas for our shared drive. That is, each user will have their own folder on our Network Attached Storage (NAS) that has a size limit. I can successfully mount the shared drive, but I can't figure out how to set quotas on it (I think smbcquota might work, but I'm not sure). It's been suggested to me to give each user a share on the shared drive or to use NFS. Unfortunately, neither option works for my purposes. Does anyone know how I could give users a quota on my NAS?

  • using sed to replace two patterns within a larger pattern

    - by Hair of the Dog
    Using sed how could I replace two patterns within a larger pattern on a single line? Given a single line of text I want to find a pattern (Let's call this the outer pattern) and then within that outer pattern replace two inner patterns. Here's a one line example of the input text: Z:\source\private\main\developer\foo\setenv.sh(25): export 'FONTCONFIG_PATH'="$WINE_SHARED_SUPPORT/X11/etc/fonts" In the example above the outer pattern is "/^.*([[:digit:]]+):/" which should equal "Z:\source\private\main\developer\foo\setenv.sh(25):" The two inner patterns are "/^[A-Za-z]:/" and "/\/". Another way to phrase my question is: Using sed I know how to perform replacements of a pattern using the "s" command, but how do I limit the range of "s" command so it only works on the portion of the input string up to the "(25):"? The ultimate result I am trying to get is the line of text is transformed into this: /enlistments/source/private/main/developer/foo/setenv.sh(25): export 'FONTCONFIG_PATH'="$WINE_SHARED_SUPPORT/X11/etc/fonts"

  • How does Office 2008 for Mac store its Recent items?

    - by zenopolis
    I don't have access to Office 2008, but require the information for a project I'm working on. I'm mainly interested in Word, Excel and Powerpoint. This is the information I have gathered so far... The preference file is: ~/Library/Preferences/com.microsoft.office.plist The property keys take the form: 2008\File Aliases\{APP}{n} 2008\MRU Access Date\{APP}{n} where {APP} represents an Office application, and {n} represents a number starting from 0. The applications are represented by the following values: MSWD (Word) XCEL (Excel) What value represents PowerPoint? In the property list I've seen, the numbers represented by {n} range from 0-10 (11 items). Is 10 the limit? or is this unrestrained? Finally, I've noticed that Office 2011 does not add its Recent Items to the Apple System menu: Apple > Recent Items Is Office 2008 the same?

  • load search results into a div that toggles with other divs

    - by Z. Edwards
    I am working with a page that has multiple divs that toggle. This function works. A search function was added and this works too. The problem with the page as it exists currently: The search bar was placed on the "default" div and the results load below the bar into another div that is invisible when empty. The results div is inside this first default div. If you toggle to another div, you lose the default div and can't get back to it. For this reason, I moved the search bar to the left navigation where the other toggle links are situated. I also moved the search results div out of the default div to "stand on its own." What I am trying to do: Make the search button show the div with the results as well as find the results. Basically, to integrate the search function into the array/toggle function. The search function is in one .js file and the toggle function is in a different .js file. I keep thinking there must be a way to get "onclick" to call from both .js files so that I don't have to do a bunch of extra work combining the two functions that already exist and work separately. I am a Javascript newbie learning by examples and haven't been able to figure this out. I have never seen a working example of this and my searches haven't produced one. I would be very grateful for any help. Hope I explained the problem adequately. Edit: Here is the code I already have for the toggle function. var ids=new Array('a','b','c',[and so on--search results not added here yet]); function switchid(id_array){ hideallids(); for( var i=0, limit=id_array.length; i < limit; ++i) showdiv(id_array[i]); } function hideallids(){ for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById(id).style.display = 'none'; } else { if (document.layers) { // Netscape 4 document.id.display = 'none'; } else { // IE 4 document.all.id.style.display = 'none'; } } } function showdiv(id) {//safe function to show an element with a specified id if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById(id).style.display = 'block'; } else { if (document.layers) { // Netscape 4 document.id.display = 'block'; } else { // IE 4 document.all.id.style.display = 'block'; } } } function initialize(){ var t = gup("target"); if( t ) { switchid([t]); } } function gup( name ) { name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ){ return ""; } else { return results[1]; } } Thanks in advance!

  • USB Permission - Write protection

    - by dekhadmai
    I have an external harddisk and my friends asked for it. The point is I don't trust in his anti-virus software. Is there anyway to allow some folders (I prepare hdd space for him) to write-able and all others is read-only ? or is there a software that can do like this ? And it would be great if I can have full access on my computer ONLY (may be with some specific software on my PC) and without having to modify anything. I don't ask for hdd-encryption since I only want to limit the area of write-able folder (and allow my friend to read through all my data), later I can scan for virus myself only in that area ... scanning entire hdd with 500gb/friend is not fun at all ! Sorry if this doesn't seems like the programming questions. Any help would be appreciate, Thank you.

  • Ubutu Server Edition: useful for the home user?

    - by D Connors
    My question is simple. What (if anything) does Ubuntu Server Edition have to offer to home users? This question is mostly out of curiosity really, but I like asking. I've got a home network set up here with some 6 to 7 machines (most Windows, one Linux). And I was wondering how useful would it be to have a dedicated computer in my house running Ubuntu Server full time. We've had an awful experience with file sharing so far, would it simplify file sharing/transferring? Would I be able to limit the internet bandwidth granted to each PC? Would I be able to monitor in/out internet traffic (both real time and monthly statistics)? Last, and most important, if I'm completely off as to what Ubuntu Server actually is, please say so. I am completely new to it.

  • Restricting server.log file size (minecraft) in CentOS

    - by MisdartedPenguin
    I'm currently running a bukkit (minecraft) server which generates a server.log file with all the console messages / errors. Every now and then I have a plugin (which i need) that crashes and can cause the server.log file size to increase dramatically. I've had it hit 32GB before which used all my disk space. Is there a way to make it a rolling log (deletes old errors) or be able to limit the file size so it can't go above say 10MB. But the solution needs to not affect how the server runs so it doesn't throw an error when it can't write anymore. Anyway of doing this with CentOS?

  • Too many files open issue (in CentOS)

    - by Ram
    Recently I ran into this issue in one of our production machines. The actual issue from PHP looked like this: fopen(dberror_20110308.txt): failed to open stream: Too many open files I am running LAMP stack along with memcache in this machine. I also run a couple of Java applications in this machine. While I did increase the limit on the number of files that can be opened to 10000 (from 1024), I would really like to know if there is an easy way to track this (# of files open at any moment) as a metric. I know lsof is a command which will list the file descriptors opened by processes. Wondering if there is any other better (in terms of report) way of tracking this using say, nagios.

  • setting my mysql server - limiting domains that can connect

    - by Alex
    I am trying to setup a mysql server on my machine. I would like to limit the domains that it listens for connections to. My understanding is that you can either have it listen to 1 ip or all ip's. Therefore, if i want to connect remotely I have to say all ips. Then I would like to block all domains but the ones I know should actually be connecting.. I believe this is done through windows firewall. However, how do i do this by domain instead of IP?

  • Ubuntu upstart hangs on interactive start & stop

    - by danorton
    How do I get Ubuntu upstart to not hang on interactive start & stop? I have created many upstart scripts that work fine during init, but often hang when I enter them at the console. If I CTRL+C out, all that happens is that the job changes state. The script is never run. I’m running Ubuntu Lucid on a Xen virtual server with a Linux 2.6.39 kernel. Below is merely a representative example of many scripts that behave this way: description "apache2" start on local-filesystems \ and (net-device-up IFACE=lo) \ and (runlevel [2345]) stop on runlevel [016] respawn respawn limit 10 5 expect daemon script . /etc/apache2/envvars /usr/sbin/apache2ctl start end script

  • The Disloyalty Card

    - by David Dorf
    Let's take a break from technology for a second; please indulge me. (That's for you Erick.) A few months back, James Hoffmann reported that Gwilym Davies, the 2009 World Barista Champion, had implemented a rather unique idea for his cafe: the disloyalty card. His card lists eight nearby cafes in London that the cardholder must visit and try a coffee. After sampling all eight and collecting the required stamps, Gwilym provides a free coffee from his shop. His idea sends customers to his competitors. What does this say about Gwilym? First, it tells me he's confident in his abilities to make a mean cup of java. Second, it tells me he's truly passionate about his his trade. But was this a sound business endeavor? Obviously the risk is that one of his loyal customers might just find a better product at a competitor and not return. But the goal isn't really to strengthen his customer base -- its to strengthen the market, which will in turn provide more customers over the long run. This idea seems great for frequently purchased products like restaurants, bars, bakeries, music, and of course, cafes. Its probably not a good idea for high priced merchandise or infrequently purchased items like shoes, electronics, and housewares. Nevertheless, its a great example of thinking in reverse. Try this: Instead of telling your staff how you want customers treated, list out the ways you don't want customers treated. Why should you limit people's imagination and freedom to engage customers? Instead, give them guidelines to avoid the bad behavior, and leave them open to be creative with the positive behavior. Instead of asking the question, "how can we get more people in our stores?" try asking the inverse: "why aren't people visiting our stores?" Innovation doesn't only come from asking "why?" Often it comes from asking "why not?"

  • More Mobile Payments

    - by David Dorf
    In the previous post I discussed the Bump Payments from PayPayl, but that's not the only innovative way to make purchases using your phone. Verizon recently announced a partnership with Danal that allows shoppers to charge online purchases to their Verizon bill. For e-commerce sites that accept this type of payment, it's a two step process. At checkout, the shopper enters their mobile number and billing zip code. Then a SMS message is sent to the mobile phone that contains a one-time code that must be entered on the e-commerce site. This two-factor authentication seems pretty secure, and no pre-registration or credit card is necessary. There's a $25 a month maximum, but I bet the limit gets raised as Verizon gets more comfortable with security. Merchants are charged a fee similar to credit card fees. Another example of mobile payments is offered by BlingNation. Customers attach a small NFC sticker to their phones that allows them to "tap" the POS device to make a payment. The NFC chip is connected to their checking account, so the transaction is treated as a debit payment. Text messages are sent to the mobile that confirm the payments so shoppers can easily verify their purchases. BlingNation is working with banks like Adirondack Trust Company and The State Bank of La Junta in Colorado. Heck, you can even send money to inmates in the Arkansas prison system using your mobile phone now that the state of Arkansas supports payments via their mobile website. Everyone is getting into the act now.

  • Optimize Images Using the ASP.NET Sprite and Image Optimization Framework

    The HTML markup of a web page includes the page's textual content, semantic and styling information, and, typically, several references to external resources. External resources are content that is part of web page, but are separate from the web page's markup - things like images, style sheets, script files, Flash videos, and so on. When a browser requests a web page it starts by downloading its HTML. Next, it scans the downloaded HTML for external resources and starts downloading those. A page with many external resources usually takes longer to completely load than a page with fewer external resources because there is an overhead associated with downloading each external resource. For starters, each external resource requires the browser to make an HTTP request to retrieve the resource. What's more, browsers have a limit as to how many HTTP requests they will make in parallel. For these reasons, a common technique for improving a page's load time is to consolidate external resources in a way to reduce the number of HTTP requests that must be made by the browser to load the page in its entirety. This article examines the free and open-source ASP.NET Sprite and Image Optimization Framework, which is a project developed by Microsoft for improving a web page's load time by consolidating images into a sprite or by using inline, base-64 encoded images. In a nutshell, this framework makes it easy to implement practices that will improve the load time for a web page that displays several images. Read on to learn more! Read More >
