  • Browser extension (or other software) to delay page load

    - by Doug Harris
    The alt text to today's comic at xkcd.com (strip below) says: After years of trying, I broke this habit in a day by decoupling the action and the neurological reward. I set up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected. (bold is my emphasis) Does anybody know of a browser extension or other software that will add this sort of delay? I've seen extensions which simply block sites, but not a delay like this.

  • What are performance limits of a database?

    - by Tommy
    What are some rough performance limits (read/s, write/s) for a single database server (no master-slave architecture), assuming storage on disk? How many read/s, write/s, depending on the kind of disk? (SSD vs non-SSD) , assuming simple operations (select one row by primary key, update one row, correctly indexed). I assume this limit is dependent on disk seek/write. EDIT: My question is more about getting rough metrics of the number of operations a database supports: to be able to know for example, if a new feature triggering 300 inserts/s can be supported without scaling out with additional servers.

  • Is there a Windows 7 equivalent to the *NIX ability to create a hard link to /dev/null?

    - by minameismud
    I saw another question here that the Windows equivalent to /dev/null is simply NUL. I also know that you can use the mklink command to make sym links (shortcuts) from the command line: MKLINK [[/D] | [/H] | [/J]] Link Target /D Creates a directory symbolic link. Default is a file symbolic link. /H Creates a hard link instead of a symbolic link. /J Creates a Directory Junction. Link specifies the new symbolic link name. Target specifies the path (relative or absolute) that the new link refers to. When I try to use the /j switch to make a hard link ("junction") instead of a simple shortcut to NUL, I get: C:\>mklink /j "C:\Program Files\MyNewHardlinkFolder" NUL Local volumes are required to complete the operation. I can create shortcuts to NUL all day long using the /d switch, but I would much prefer the hard link. Any ideas?

  • What do I need to connect a hard disk to my laptop via non powered eSata?

    - by Ludo
    Hi there. I'm looking at getting a hard disk for my laptop (OCZ Vertex 2 SSD) which I would like to connect via eSata. My laptop has an eSata port, but it's not powered (Thinkpad T410). I presume this means I need more than just an eSata to eSata cable as it needs power, so does this mean I need a caddy for the hard disk as well which will provide power to the drive, or do I need one of them eSata cables that has a USB attachment too? I don't think the drive will come with a power supply. I realise this seems simple but I can't find an obvious answer online. Thanks for any assistance! Ludo.

  • How to delete just one LINE of text (NOT a table-row!) with a single KEYBOARD shortcut in Microsoft Office Word 2010?

    - by Sk8erPeter
    Are there any shortcuts to delete just one row (which is NOT a table row, just a single row in a text) in Microsoft Office Word 2010? If not, how can I assign one to do it? In worst case, can I make a macro (in VB) which could do the same with a custom shortcut? To clarify my problem: I would like to avoid multiple clicks and/or pushing multiple buttons, even if I click in the middle of the line of text. :) For example, in Notepad++ I can delete the entire current line with Ctrl+L, in NetBeans, I can delete an entire line with Ctrl+E, in Eclipse, I can delete current line with Ctrl+D, etc., where it doesn't really matter where my mouse cursor is actually... so there are these simple solutions, which I look for in Word too. It really would simplify my work in huge documents.

  • "Slave" user accounts in GNU/Linux

    - by Vi
    How to make one user account to be like root for some other user account, e.g. to be able to read, write, chmod all it's files, chown from this account to master and back, kill/ptrace all it's processes and to all thinks root can, but limited only to that particular slave account? Now I'm simulating this by allowing "master" user to "sudo -u slaveuser" and setting setfacl -dRm u:masteruser:rwx ~slaveuser. It is useful as I run most desktop programs in separate user accounts, but need to move files between them sometimes. If it requires some simple kernel patch it is OK.

  • How to swap ctrl and fn key on a MacBook Pro running Windows 7 via Boot Camp?

    - by hobbes3
    There are sooooo many discussion on the internet about swapping the fn and ctrl key on a MacBook Pro. On the Mac side, a new software called ReMap4MacBook does a perfect job swapping the two key. But on the PC side (specifically Windows 7), I can't really find a definitive answer. Most post refer to this article but I read the loooong article and followed the instructions to no avail. I remember there used to be a program (maybe it was on XP) that not only swapped the two keys but it also controlled the fans on the MacBook Pro. But I can't remember the name and I also recall that that program stopped being updated like years ago. EDIT: It's called Input Remapper. So I am hoping there exist a simple program that I can simply run to swap those two keys.

  • Text tagging/analysis tool for Mac

    - by Mark Porter
    I'm a doctoral student doing research in the humanities. As part of my research I have gathered together a lot of interview text. To analyse this data I want to be able to easily tag sections of text with keywords (the tags need to be able to overlap, and perhaps be organised hierarchically) and later be able to collate those sections from across multiple files. I need to be able to do this on a Mac. It feels like a simple task but I can't find any software for doing it that isn't either horribly clunky or a massive overkill worth hundreds of pounds. Is there any good software for doing this, or are there any good ways of doing it with other software?

  • network user isolation

    - by seaquest
    My question is for a network with a Linux iptables router gateway. How can it be possible to prevent inter-network traffic of those users. Think this case as a public network, IPs are distributed through linux gw and users are authenticated thru the gateway. We want to protect public users from public users. Network is not wireless and I can not use Wireless AP user isolation. Actually I have a simple method. Subnet the network into /30 mask. Give minimum IP of each subnet to the gateay and ditribute those /30 IPs from the subnet. But this is pretty costly for such an aim. I want to ask for other methods Thanks.

  • World's simplest, LIGHTEST email client?

    - by rekindleMyLoveOf
    I do not want the bloat that is outlook, nor do I need exchange server-like nifty features. Most certainly do not want the bloat that is thunderbird. I just want to be able to send and receive email as/with the particular email account I set up on my domain. Pocomail sounded like a nice idea but apparently it does not deal with html and since this is for a tiny fledgling biz, i think I might need to accomodate html... so I didn't investigate further. Too bad gmail won't let me send from my own mail server, really. :o) What do you guys use that simple and nifty? ===edit=== forgot to mention this is going to be on Windows Vista. (Hey, I'm not a "superuser", okay? I got bounced from stackoverflow :-) )

  • Installing MoinMoin -wiki to my user directory on a server with no root access

    - by deiga
    Hello all, I posted this on webapps, but they told me to come here :) I've been trying to install MoinMoin -wiki on this webserver, where I have no root access. The server doesn't support wsgi, but it does support cgi/fcgi/etc. I've scoured google for a simple guide on how to accomplish this, but the only guides I found were from the year 2004 or so. Other guides always assumed that one has root access. So can anyone link a good tutorial for my question or just help me out here? Your help is appreciated :) P.S. Sorry if this is the wrong stack -page

  • Time difference between servers after disaster recovery

    - by Sandokan
    We are running an old training system based on Windows Server 2003 and XP-clients. The solution is rather simple with four servers, two of them beeing DC:s. Everything is preconfigured and that goes for backup scheme as well. The backup software is Symantec BackupExec 2010. The scheme is a standard GF-F-S routine with full backups running once a week on Sundays. The other six days run differential backups. Now let's say in a worst case scenario, a server crashes on Saturday and we have to restore it from backup. The last backup will then be six days old and thus it will come online with six days old configurations. Will this pose a problem for the other servers or will the recovered server "get in line" eventually?

  • How to sum cells depending on the content of a neighbor cell

    - by dannymcc
    I have an Excel document with the following columns; Date | Reference | Amount 23/01/11 | 111111111 | £20.00 25/09/11 | 222222222 | £30.00 11/11/11 | 111111111 | £40.00 01/04/11 | 333333333 | £10.00 31/03/11 | 333333333 | £33.00 20/03/11 | 111111111 | £667.00 21/11/11 | 222222222 | £564.00 I am trying to find a way of summarising the content in the following way; Reference : 111111111 Total: £727 So far the only way I have been able to achieve this is to filter the list by each reference number (manually) and then add a simple SUM formula to the bottom of the list of amounts. Are there any tricks that anyone knows that may speed this up? What I am trying to achieve is a spreadsheet that highlights each reference number that collectively exceeds over £2,000.

  • Sharing VPN from XP to Linux virtual

    - by user55513
    Hi I will keep the question simple with few details, if more is needed tell me. Thanks. I am playing around with networking and virtualbox. So I have 2 virtual machines. One is windows xp and another has linux in it. Windows XP has 2 network cards. One for the internet and the other to connect to the linux computer. Linux has one 1 card and it can only access the internet passing through Windows XP. Internet works fine until I activate OpenVPN on Windows. When I turn on VPN, Linux has no access to it. How can I make linux use VPN too? I believe it has something to do with using the "route" command on XP to send VPN traffic to Linux but I was not able to figure it out how yet.

  • How can I set up a rule in outlook for an alias account?

    - by lucy
    I have 4 email aliases that all deliver to the same outlook inbox. 2 of them are stop@ addresses to be included in a mailing unubscribe link. Using the simple rules in outlook doesnt work, unless we set them to move emails titled stop, but for ease of unsubscribing, we do not want responders to have to do anything other than send a blank email to the stop@ address. Our IT guy tried to sort this out, by setting up a rule that all emails sent to stop@ got into a specified folder (stop folder created within inbox), but now, all that happens is all my emails go into the wrong boxes!!! Any help would be appreciated

  • SQL server 2000 reporting bad values to ASP.Net Application

    - by Ben
    I have an instance of SQL server 2000 (8.0.2039) with a rather simple table. We recently had users complain about an application I wrote returning bad values for some of the dates in the databse. When I query the table directly via Server Management Studio, it will return the correct values, however the identical queries from my application report the wrong values, but only for a couple of dates. I have been over the code, and it is solid. If the error was in the code, all of the dates reported should be wrong. I have also run the code on an identical test database, and everything is reported properly. I believe the problem may lie in the sql instance itself, which is why I am posting in Server Fault. My question is, has anyone heard of a database reporting bad (incorrect) date values when queried via web application? It should be noted that this particular server was once manually rebuilt after having a cluster clean run on it.

  • Bad request - Invalid Hostname Error when using ARR IP address

    - by syloc
    I'm trying to setup a simple ARR system. I have 1 ARR machine load balancing between 2 APP servers. I can reach the app sites if i use the server name of the ARR machine. (http://arrserver/app) But i can't do it with its IP address. (http://10.7.10.25/app). It gives the "Bad Request - Invalid Hostname". In the ARR machine i configured the default site's bindings to "All Unassigned","80" (default values). Do i need to change the binding rule or need additional url rewrite rules? And also, in the ARR server http://127.0.0.1/app doesn't work. But http://localhost/app works fine. Thx in advance

  • Advanced (?) Excel sorting

    - by Preston Grayskull
    First of all, I'd like to admit that I don't really know anything about Excel, but I have tried to look up a solution to this in Excel books and Googling. Here's what I'm trying to do: I have a really long spreadsheet There are 7 columns total, but only two columns that I'm most interested in. Here's an example CSV that is much more simple than my actual dataset, but the search/sort is analogous: John, Apple Dave, Apple Dave, Orange Steve, Apple Steve, Orange Steve, Kiwi Bob, Apple Bob, Banana I'm interested in extracting the entire rows (all of the columns) that meet the following criteria: ["Apple"] OR ["Apple" and "Orange"] NOT ["Apple" and "Orange" and Anything Else] NOT ["Apple" and Anything that isn't Orange] So with the above CSV, I would get the entire rows for John and Dave, but not Steve and not Bob. I started doing this manually, and will likely finish by the time this question has an answer, but I would like to know this for future reference. Thanks!

  • How can I keep gnu screen from becoming unresponsive after losing my SSH connection?

    - by Mikey
    I use a VPN tunnel to connect to my work network and then SSH to connect to my work PC running cygwin. Once logged in I can attach to a screen session and everything works great. Now, after a while, I walk away from my computer and sooner or later, the VPN tunnel times out. The SSH connection on each end eventually times out and then I eventually come back to my computer to do some work. Theoretically, this should be a simple matter of just restarting the VPN, reconnecting via SSH, and then running "screen -r -d". However apparently when the sshd daemon times out on the cygwin PC, it leaves the screen session in some kind of hung state. I can reproduce a similar hung state by clicking the close box on a cygwin bash shell window while it's running a screen session. Is there any way to get the screen session to recover once this has happened, so that I don't lose anything?

  • Security tips for adding wireless AP to domain network?

    - by Cy
    I am researching best-practices for adding wireless to our existing domain network. My DHCP server is running Windows Server 03 Standard (not sure if thats useful). I am familiar with simple home networking but I thought I'd get some expert advice for the more advanced stuff. Any tips and / or best-practices? Is this Cisco Wireless Access Point a good option? Are there any additional hardware recommendations? Thank you in advance for your help.

  • Reverse proxy using hop and RDP

    - by Sergei
    I am trying to connect from Vista to XP using RDP via reverse proxy using putty and an intermidiate host. There are myriad articles on the internet how to do it using vnc, ssh servers, winsshd, etc, but I can't find anything that helps me in this specific case. What I have: Windows XP host behind the firewall - 'destination' linux host running ssh on the internet - 'intermediate' windows host behind the firewall - 'source' All I want to do is open reverse tunnel from destination to intermidiate and use this tunnel for connecting back from the source. That should be simple to setup, however I just cannot make it. This is what I do: On 'destination', open putty session, create tunnel to 'intermediate' using following settings: source port 3389, destination is 'source:33389', direction is local On 'source', open putty session, create tunnel to 'intermediate'using following settings: source port 33389, destination is 'destination:33389', direction is local Finally, on source, open termnal services client and connect it to localhost:33389.Unfortunately it seems like packets do go somewhere but eventually client times out. Am I totally misunderstanding the concept? Please help!

  • a load balancing scenario using HAProxy and keepalived shows no performance advantage

    - by chakoshi
    Hi, I am trying to setup a load balanced web server scenario, using two HAproxy load balancers and two debian web servers following this guide http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-keepalived-on-debian-lenny. the setup is working but the results of simple performance benchmarking is not what I expected. I tried apache benchmark tool to send lots of requests to servers (one time directly testing one of the web servers and the other time testing through the load balancer) using the command "ab -n 1000000 -c 500 http://IP/index.html", but the test results shows better performance for the single server without load balancer. can any one tell me if I'm going wrong on some thing?

  • mailman not relaying email to external address

    - by gozzilli
    I have a setup of mailman with postfix on an ubuntu server 12.04. My problem is that mailing list emails are not forwarded to email addresses external to my institution. However the initial welcome email is received by everyone, internally and externally. in fact, a simple email from command line with mail is successfully sent to anyone after that, mailing list emails are only forwarded to internal addresses. the domain name I'm using for the server is not that of my institution who is hosting the server. Here is my main.cf: myorigin = sub.myinstitution.tld mynetworks = 127.0.0.0/8 xxx.xxx.xxx.xxx/16 # this is my institution ip range relayhost = smtp.myinstitution.tld inet_interfaces = loopback-only local_transport = error:local delivery is disabled virtual_alias_maps = hash:/etc/postfix/virtual smtpd_recipient_restrictions = permit_mynetworks myhostname = mywebsite.tld mydestination = $myhostname, localhost.$mydomain, localhost I also found these two links on serverfault and ubuntu forums, but neither of these solutions seem to do the trick for me. Any help would be much appreciated.
