  • Open Source Excel training documentations?

    - by William
    I'm a trainer, basically. I'd like to find some sort of Excel-based training that's under the creative commons, or another awesome license. I want to use it to train others, and make it better. If this doesn't exist, I may have to write it. Because it should.

  • Is there any very bare minimal ftp server for ubuntu that wouldn't conflict with other installed servers?

    - by Disco
    I have installed proftpd with mod-sql modules; i need to have a ftp server that would run on another port (and use a separate authentication scheme) Whenever i try to install vsftpd or pureftpd it simply removes proftpd and dependencies; i'm guessing it's to prevent having conflicts ... Is there any 'very small' ftp server; like run from command line that I could use ? I've searched all around but cannot find ... Any help would be appreciated

  • IF function that refers to another cell if true

    - by geoconfusion
    Can someone please help? I am using the IF function to find cells within certain ranges, but want the cell to contain the value if it falls within that specific range. for example: =IF (AA3 is between 150 and 400 then AD3 is equal to AA3 and if not leave blank) my current formula below does not work: =IF(AND(AA3150, AA3<400), AD3=AA3, "" ) where AD3 is the cell I am working in... any suggestions?

    Hi, I'm looking for a solution that'll automatically sync file system changes in "/folder1" to "/folder2". Any change should be synced (deleted files, new folders etc.) without any confirmation.

I can't seem to find just the right tool. Does anyone

    - by hevets
    I'm a Web Developer who has just made the switch over to Mac. Despite all that I know and love about the Windows environment I find myself in a new mysterious place. My question: what is the best Apache, PHP setup for a Mac developer? On Windows I've been using WAMP which was quite nice, I know Mac comes shipped with Apache 2 and PHP pre-installed. I'm just wondering if there is a better solution out there.

  • Exchange 2003 very reliant of 1 on 4 AD servers, Freezes without it

    - by user56717
    On-site we have 3 of 4 AD servers (AD1,AD2 and AD4) with AD1 having most of the Operational Master Roles, however when AD2 goes down, freezes or reboots outlook says 'waiting for exchange server AD2', when exchange is on a different box completely. AD4 was just built from scratch and added hoping to get around this reliance on AD2 but it doesn't seem to have any effect, had a look through exchange settings and couldn't find any locations it points to AD2 and no other active directory servers. Would appreciate some help on the matter, Thank You

  • html5 video and Windows 7N

    - by Tim Brigham
    When using Windows 7N and embedded videos for YouTube and the like my users have been getting a black box. I tracked this down to when HTML5 is being used for rendering. Other than putting a bunch of sites in compatibility mode or installing the Windows Media Pack (which resolves this issue) is there another route I can take? My guess is it's only a single registry key or DLL that says 'I'm not HTML5 compatible' but I don't have any idea how to find it.

  • Change section key to less-than in OS X

    - by onik
    I'm having trouble getting my keyboard layout to be properly recognized. At the moment everything else is fine, but my less-than key (<) is mapped to the section key (§), which makes writing HTML a pain. I've tried Ukelele and KeyRemap4MacBook, but can't seem to find the correct settings to change. For reference, this is my layout: Finnish Multilingual, and in System Preferences the input is set to Finnish.

  • bandwidth throttling C linux

    - by bob moch
    hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.
