  • How to properly use the .animate() function -- top

    - by sadmicrowave
    Is this the proper way to use the .animate(top) function? Positive number (animate down)-- $("div#container div#history-menu").animate({top:'180px'}, 600); Negative number (animate up)-- $("div#container div#history-menu").animate({top:'-180px'}, 600); Because I'm getting a java error in my error console that says: "error in parsing value for property 'top'. Declaration Dropped."

  • How can I perform a reverse string search in Excel without using VBA?

    - by e.James
    I have an Excel spreadsheet containing a list of strings. Each string is made up of several words, but the number of words in each string is different. Using built in Excel functions (no VBA), is there a way to isolate the last word in each string? Examples: Are you classified as human? - human? Negative, I am a meat popsicle - popsicle Aziz! Light! - Light!

  • Why is domU faster than dom0 on IO?

    - by Paco
    I have installed debian 7 on a physical machine. This is the configuration of the machine: 3 hard drives using RAID 5 Strip element size: 1M Read policy: Adaptive read ahead Write policy: Write Through /boot 200 MB ext2 / 15 GB ext3 SWAP 10GB LVM rest (~500GB) emphasized text I installed postgresql, created a big database (over 1GB). I have an SQL request that takes a lot of time to run (a SELECT statement, so it only reads data from the database). This request takes approximately 5.5 seconds to run. Then, I installed XEN, created a domU, with another debian distro. On this OS, I also installed postgresql, with the same database. The same SQL request takes only 2.5 seconds to run. I checked the kernel on both dom0 and domU. uname-a returns "Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux" on both systems. I checked the kernel parameters, which are approximately the same. For those that are relevant, I changed their values to make them match on both systems using sysctl. I saw no changes (the requests still take the same amount of time). After this, I checked the file systems. I used ext3 on domU. Still no changes. I installed hdparm, and ran hdparm -Tt on both systems, on all my partitions on both systems, and I get similar results. Now, I am stuck, I don't know what is different, and what could be the cause of such a big difference. Additional Info: Debian runs on a Dell server PowerEdge 2950 postgresql: 9.1.9 (both dom0 and domU) xen-linux-system: 3.2.0 xen-hypervisor: 4.1 Thanks EDIT: As Krzysztof Ksiezyk suggested, it might be due to some file caching system. I ran the dd command to test both the read and write speed. Here is domU: root@test1:~# dd if=/dev/zero of=/root/dd count=5MB bs=1MB ^C2020+0 records in 2020+0 records out 2020000000 bytes (2.0 GB) copied, 18.8289 s, 107 MB/s root@test1:~# dd if=/root/dd of=/dev/null count=5MB bs=1MB 2020+0 records in 2020+0 records out 2020000000 bytes (2.0 GB) copied, 15.0549 s, 134 MB/s And here is dom0: root@debian:~# dd if=/dev/zero of=/root/dd count=5MB bs=1MB ^C1693+0 records in 1693+0 records out 1693000000 bytes (1.7 GB) copied, 8.87281 s, 191 MB/s root@debian:~# dd if=/root/dd of=/dev/null count=5MB bs=1MB 1693+0 records in 1693+0 records out 1693000000 bytes (1.7 GB) copied, 0.501509 s, 3.4 GB/s What can be the cause of this caching system? And how can we "fix" it? Can we apply it to dom0? EDIT 2: I switched my virtual disk type. To do so I followed this article. I did a dd if=/dev/vg0/test1-disk of=/mnt/test1-disk.img bs=16M Then in /etc/xen/test1.cfg, I changed the disk parameter to use file: instead of phy: it should have removed the file caching, but I still get the same numbers (domU being much faster for Postgres)

  • How can I get an SFTP server running on Windows 2008?

    - by Saul
    I have a remote Windows 2008 machine and the task at hand is to share out parts of its filesystem via SFTP for a single user. Were commercial software an option things would be easy but I want freeware. After trying out several different candidates such as Core FTP Mini SFTP Server, SilverShield and freeFTPd none them really qualified - either connection issues, zero configurability or bugs. Is there a free and stable SFTP server for Windows 2008 which works out of the box?

  • How to stabilize a disconnecting internet connection?

    - by All
    My internet connection is very interrupting, but it is not sensible for web surfing, as the connection dies for a few seconds and everything is OK. The IP is NOT changing, and just a halt in data transfer. However, it is very annoying for applications needing contact connection like SSH. Since it seems disconnection, SSH closes. Is there any way to stabilize this kind of interrupting connection to keep the connection with zero transfer data to persevere any connection like SSH? I am using Linux (Debian/Ubuntu).

  • Zabbix not getting data for one filesystem

    - by Dennis Williamson
    I have Zabbix monitoring disk space for several volumes on several servers. It works fine on all of them except for one of the volumes on one of the servers which always reports as 0. However, when I run ./zabbix_get -s localhost -p 10050 -k 'vfs.fs.size[/home, free]' locally on the machine in question, it gives me the correct, non-zero size which matches the output of df. How can I go about troubleshooting and correcting this problem?

  • Do Windows Vista/7 have memory protection?

    - by winnewb
    Is it possible for a program to access another program's memory directly and read from (or write to) it, or to "inherit" the old contents of memory reclaimed from another program? (ie if it doesn't zero out memory before using it and just reads from unitialized memory directly)

  • Python - counting sign changes

    - by dadashek
    I have a list of numbers I am reading left to right. Anytime I encounter a sign change when reading the sequence I want to count it. X = [-3,2,7,-4,1,-1,1,6,-1,0,-2,1] X = [-, +, +, -, +, -, +, +, -, -,-,+] So, in this list there are 8 sign changes. When Item [0] (in this case -3) is negative it is considered a sign change. Also, any 0 in the list is considered [-]. Any help would be greatly appreciated.

  • My VPS ubuntu server is very slow

    - by askmike
    I just installed a frech copy of Ubuntu 12.04 on my vps because my old installation was very slow, unfortunately this did not fix the problem. With slow I mean requests for my PHP websites take a long time, very slow (30 sec per request) to slow (3+ sec per request). When it's really bad SSH is also laggish. The websites are: askmike.org (pretty standard Wordpress) mvr.me (own PHP) slow? very slow: Here is a picture of loading a clean install of wordpress slow: here is a picture of loading a small PHP based website the vps The VPS has 256mb ram and an 25GB hdd. Besides serving the 2 small websites it isn't doing anything AFAIK. What have I installed Clean Ubuntu server 12.04 LAMP stack few things like git and nodejs (not using both) ossec (because I thought my server was getting hammered) munin What I already tried / done I installed munin so that I could watch io speed and such. The problem is that I don't know where to look for in the munin report. I checked logs and don't see anything strange (although I don't really know where to look for besides strange / repetitive errors and GET requests). I configured Apache MPM to: <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 40 MaxRequestsPerChild 0 </IfModule> (apache is using prefork, the default) Stats I copied the munin report as it appeared at 4:50 last night to a site hosted on a shared webhost. Note that tonight my mysql crashed somewhere after 1:00 (which is a new problem altogether), so therefor the graph for last night might look strange. Can anyone help me get my VPS up to normal speed? EDIT: Thanks for the replies. The VPS is 10 bucks a month and is from directvps.nl (Dutch host and I'm also dutch). I did two speed tests for disk IO: $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 23.1506 s, 46.4 MB/s $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 39.3796 s, 27.3 MB/s Anyway: how can I prove to my VPS host that it is to slow? I can understand a server being busy slowing a website down. But 5-30 sec loadtime for a normal PHP webpage?

  • BFS algorithm problem

    - by Gorkamorka
    The problem is as follows: A wanderer begins on the grid coordinates (x,y) and wants to reach the coordinates (0,0). From every gridpoint, the wanderer can go 8 steps north OR 3 steps south OR 5 steps east OR 6 steps west (8N/3S/5E/6W). How can I find the shortest route from (X,Y) to (0,0) using breadth-first search? Clarifications: Unlimited grid Negative coordinates are allowed A queue (linked list or array) must be used No obstacles present

  • Fastest possible summing numbers up to N

    - by dada
    Okay so i need really FAST algorithm or code in C if you have any it would be nice. The task is to sum all numbers from 1 to N for a given number N (it can be negative number too), so i did the usual way (you know just summing with loop from 1 to N) but it's not fast enough - i need something faster, i guess that i need the fastest possible way to do this. If anyone could help me, please do. Thanks.

  • Benefits to private networks between virtual machines on an ESXi host?

    - by arex1337
    I'm planning this development environment with a few database servers, and originally thought I would have a few private networks. I then thought it might be unnecessary as the ESXi cluster already provides redundancy with 4 NICs (in my case) and should manage the network traffic pretty intelligently, right? Two private networks Zero private networks What are the advantages/disadvantages between the two shown configurations - on an ESXi 4.1 host?

  • Unsigned Integer

    - by viswanathan
    I was curious to know what would happen if i assign a negative value to an unsigned variable. The code will look somewhat like this. unsigned int nVal = 0; nVal = -5; It didnt give me any compiler error. When i ran the nVal was having strange value. Could it be that some 2's complement value gets assigned to nVal.
