  • Is it possible to keep mysql migration running without keeping connection open?

    - by taw
    ALTER TABLE can easily take a few days - and during this time there's a non-negligible chance of connection getting terminated due to network problems. Is it possible to start ALTER TABLE (or CREATE TABLE ... SELECT ...; or some other very long running query) and leave it running without keeping connection open all the time? (the obvious solution of screen + console mysql client won't easily work as there's no ssh running on that server, only mysqld).

  • Can I remove the labels from the bibliography, while keeping them in citations?

    - by Tae
    I'm writing the bibliography of my report with thebibliography environment because I don't need a BibTeX database (or I don't have the time for learn how to customize or write a style). Well, using the optional argument [label] I can specify as I want the cite references are show, for example: \bibitem[PNUD1996]{PNUD1996} PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. So, if I write: in \cite{PNUD1996}. it produces: in [PNUD1996]. But the label also appear in the bibliography: [PNUD1996] PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Can I to remove the label from the bibliography and keeping it in the reference? I mean, to get: in [PNUD1996]. and PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Thanks, and sorry for my English :(

  • Rails - how do you create a user index page like stack overflows with multiple tabs whilst keeping t

    - by adam
    On stackoverflow in the users profile area there are many tabs which all display differing information such as questions asked and graphs. Its the same view though and im wondering hows its best to achieve this in rails whilst keeping the controller skinny and logic in the view to a minimum. def index @user = current_user case params[:tab_selected] when "questions" @data = @user.questions when "answers" @sentences = @user.answers else @sentences = @user.questions end respond_to do |format| format.html # index.html.erb nd end but how do i process this in the index view without a load of if and else statments. And if questions and answers are presented differently whats the best way to go about this.

  • How to double the size of 8x8 Grid whilst keeping the relative position of certain tiles intact?

    - by ke3pup
    Hi guys I have grid size of size 8x8 , total of 64 Tiles. i'm using this Grid to implement java search algorithms such as BFS and DFS. The Grid has given forbidden Tiles (meaning they can't be traversed or be neighbour of any other tile) and Goal and Start tile. for example Tile 19,20,21,22 and 35, 39 are forbidden and 14 an 43 are the Goal and start node when the program runs. My question is , How can i double the size of the grid, to 16x16 whilst keeping the Relative position of forbidden tiles as well as the Relative position of start and goal Tiles intact? On paper i know i can do this by adding 4 rows and columns to all size but in coding terms i don't know how to make it work? Can someone please give any sort of hints?

  • What is the best way to downscale mp4 video while keeping it as sharp as possible?

    - by Brandon Durham
    I've got an .mp4 file that's currently 830x1100 (it's a screencast) that I need to resize down to 114x150. I've been experimenting for hours with ffmpeg settings and nothing comes out looking nice and sharp. The original file looks decent, and I can't figure out why the downscaling makes it look so blurry. Unfortunately I can't share the video because it contains a walkthrough for software that hasn't yet been released.

  • nginx - Redirect specific page paths to https while keeping everything else on http (in a single server call)?

    - by Kris Anderson
    From what I've gathered so far it's clear that running if statements in nginx should be avoided at all costs. Most of the examples I've found so far regarding specific page redirects involve multiple servers being used. But, isn't that a bit wasteful? I'm not sure, but I would think multiple servers to accomplish this would be somewhat slower then a single server when under heavy load. My current server call is this: server { listen 10.0.0.60:80; listen 10.0.0.60:443 default ssl; #other code } What I want to do is redirect certain http requests to https requests. For example, I want /login/ and /my-account/ to always be forced to use SSL. If you're on /help/ though, I want that served over the default http. Is there a way to accomplish this within a single server call? Or is there no downside to using 2 server calls to get this working? nginx seems to be under pretty active development and a lot of the older guides I've followed were from times when you couldn't listen to requests for port 80 and 443 within the same server call. But now that nginx has been updated to support that (I'm running 1.2.4), I'm wondering if there's a "best practice" way of handling this today. Any help would be greatly appreciated. EDIT: I did find this guide: http://redant.com.au/blog/manage-ssl-redirection-in-nginx-using-maps-and-save-the-universe/ and I updated my code as follows: map $uri $my_preferred_proto { default "http"; ~^/#/user/login "https"; } server { listen 10.0.0.60:80; ## listen for ipv4; this line is default and implied listen 10.0.0.60:443 default ssl; if ($my_preferred_proto = "none") { set $my_preferred_proto $scheme; } if ($my_preferred_proto != $scheme) { return 301 $my_preferred_proto://mysite.com$request_uri; } It's not working though. When I change the default to https everything is redirected to SSL so it does somewhat work. But the redirect of /#/user/login is not redirecting to HTTPS. Any ideas? Also, is this a good way to go about this?

  • Is keeping the primary hard disk as disk C: still relevant?

    - by Jeremy French
    Back in the day, floppy disks were a: and if you were lucky b:, then when permanent storage came along c: was the default for hard disks (as I remember it) Now that many computers no longer have floppy disks is it possible to have your primary hard disk as A: is the convention out dated? Removable drives (like DVDs and flash readers) now seem to take lower precedence than permanent storage so it is a bit of an oddity that floppy disks should have higher letters.

  • How can I sort my data while keeping paired rows together?

    - by Joe Lee Frank
    How can I pair two rows on a spreadsheet, so that for each data entry I can sort the matrix but the pair of rows moves as a single list of data, retaining the structure of the two rows? For example: Original entry A1,1 B1,1 C1,1 D1,1 A1,2 B1,2 C1,2 D1,2 A2,1 B2,1 C2,1 D2,1 A2,2 B2,2 C2,2 D2,2 Sorted reverse order A2,1 B2,1 C2,1 D2,1 A2,2 B2,2 C2,2 D2,2 A1,1 B1,1 C1,1 D1,1 A1,2 B1,2 C1,2 D1,2

  • How to copy partition from one disc to another (boot partition keeping all the vital data)?

    - by Patryk
    I have bought a new laptop but the HDD, which runs at 5400 rpm, is not sufficient for me. The laptop runs Windows 7 64-bit. I have my 'old' one (a better one - Seagate Momentus 7200 rpm) and I would like to replace it but without reinstalling everything. And there my question arises: can I copy my boot partition from my laptop hard drive to my old drive so that it will boot from it properly? If so, then how to do it? Will Norton Ghost be useful here? My point would be to just replace this partition and leave the rest.

  • Keeping my zsh or bash profile synced up on all my machines.

    - by Joseph Silvashy
    I work on several different machines, all of which are *nix. I have a lot of specific things I like my shell to, or the prompt to look like, or aliases, etc, etc. I'm sure all of you folks deal with this as well. What do you think the best way to keep all my machines' shells to act the same? First off, I'm aware that different machines will need different paths to bins and other differences, so my first inclination is to just include a file at the end of my profile, this is the one that we'll keep in sync. What is the best way to keep files synced up? I can put the file on a remote system, and perhaps use git, to push, then pull my changes every once and a while. However, isn't Rsync better suited for this?

  • Why is lighttpd and fastcgi keeping sending me the *.scgi file instead of the website content?

  • How can I clear *old* browsing data from Google Chrome Linux, while keeping more recent data?

    - by Norman Ramsey
    I can find plenty of information on how to clear Google Chrome's recent browsing data, in various periods, as well as clearing all browsing data. But I want to clear old browsing data—say for a start, anything over two months old. (I'm trying to save space on a crowded laptop.) Does anyone know any principled way to do this, or shall I just dive into ~/.config/google, start removing likely-looking files, and hope for the best. I run Google Chrome on Debian Linux.

  • Why does Finder keeping showing me menus in Spanish?

    - by Ian C.
    This has happened before. A full reboot fixed it. This time: no go. The bottom of my menus, when I command-click on a file in Finder, are in Spanish. You can see a screen grab here: http://twitpic.com/10c63y How can I stop this from happening? I'm sure I inadvertantly hit a key combination that did this, but I'm stumped as to what that was. My System Preference settings for Language & Text have language set to Canadian English.

  • How can I figure out exactly which process is keeping my Mac from going to sleep and waking it up?

    - by pattern86
    I have read this knowledgebase article, but would like to know if there's a way to tell exactly which process is causing my Mac not to follow the sleep schedule I have set in System Preferences Energy Saver. I have narrowed it down to a being a process and will explain why I think so (see below). I am running OS X (10.6.5) on the new iMac 27" and I am certain it's not the following: The "Wake for Network Access" checkbox in Energy Saver settings (has never been a previous issue) Peripherals (has never been a previous issue) Any active GUI application (all are closed) Additional USB/FireWire drives (none are connected) Bluetooth (it's off) Sharing services (has never been a previous issue) The symptoms are as follows: The computer doesn't go to sleep at the predetermined time. It will wake up some number of hours after being put manually to sleep (but not within the first few seconds/minutes.) Is there a specific string I should be looking for in Console? I have tried searching for "wake" and "sleep" but can't make total sense of the results.

  • How do I batch-downsize images on linux, while keeping small images small?

    - by Gabriel
    I have a whole lot of photos and it's time to clean up the mess and free some disk space. I know mogrify is great to batch-resize things down. The problem is, in some directories I have small images mixed with the big ones. I'd like to batch-downsize all the big one but not upsize the small ones. As an example, I have a rep with tens of MBs-pictures in the 3000x2000s. Some of them I have already downsized so I could email them. They may be 1024x768. I'd like to downsize the big ones to 1600x1200, a disk-space-to-quality tradeoff I like. But then, with mogrify or convert, the small ones will be upsized, which would be a waste of disk space. I found some tricky ways to use identify with cut and some scripting to filter the small pics out and mogrify the others, but man, there's got a way to tell mogrify not to upsize my pics... How ? Is there some other tool better suited ?

  • Migrating a NAS while keeping the files and their rights intact ?

    - by Entity_Razer
    Right, what we wish (or need) to do is to migrate a NAS from a old machine to a new one. problem is, we wish to keep the folder hierarchie intact, and all the settings and shares. Now I vaguely recall microsoft used to have a tool to do exactly this. It would copy the folders exactly, with the rights intact, and then remove the shares on the old machine and reactivate them on the new machine. Now is there anyone who could help me find it again, or perhaps find a better solution for it ? Much appreciated guys

  • What is the cleanest way to upgrade Fedora and also my individual installs while keeping /home?

    - by Don
    I am a professional programmer, using Fedora 10 (and a host of other packages individually installed). I use my system to telecommute. Every year or so, I go through the ritual dance, usually with a second computer and a KVM switch as I don't have office space for two monitors, to build the next version of Fedora and install all my favorite apps. Is there a better way? At least a nice way to keep track of what I need to 'add on' so that I don't have to manually install my app collection? Also, I keep /home on a separate raid-ed drive set so I can also fall prey to 'old-config-file-itis'.

  • How can I find out which service is keeping Vista from restarting?

    - by Jeff
    Running Vista on my Toshiba laptop for several years now. Recently, I noticed it will not restart - I have to power cycle it. I have enabled Verbose Status messages, so I know it's stuck at "Stopping services". Is there a way to figure out which service is not stopping? I'm hoping for some kind of log like the bootlog. I've tried looking through the event viewer - no luck there.

  • What's the best practice for keeping track of Microsoft solution stack Hot fixes and patches?

    - by melaos
    i'm currently working on a product that is build on microsoft stacks such as sql server, entity framework, wcf, c# and biztalk server. so recently we're running into weird issues on our production servers and now we're troubleshooting this issue. we're kind of lost. so we're looking into anti virus exclusion and cumulatives updates for biztalk server. but my question now is what's the best way to keep track of all the hot fixes? do we just check for them, i.e. google it up only when we have issues? i've googled online and found that there's a microsoft baseline analyzer tool. and the other thing is microsoft blog which is updated on a weekly basis which contains all the recent hot fixes. are there a better way or best way? thanks for my ignorant question.

  • How can I have Vhosts with Lighttpd on Windows and keeping PHP through mod_cgi ?

    - by Pixelastic
    Hello, I installed Lighty on Windows 7 and managed to get it correctly serve both static and PHP files (through mod_cgi). At first I got the "No input file selected" message displayed when requesting a .php file. So, I updated the doc_root value in my php.ini to match the server.document-root defined in my Lighty config, and PHP stops complaining. Then I defined a VHost to point all foo.com requests to a specific dir. It worked well for all static files but when requesting a .php file, the mod_cgi was still picking files from the doc_root defined in php.ini, not in the directory I defined for server.document-root in my Vhost. I know its what's supposed to happen, PHP follows the config defined in php.ini. And I have to set this value in my php.ini otherwise no php is processed at all. What I don't understand is how I'm supposed to have virtual hosts with mod_cgi enabled here ? I tried adding [HOST=foo.com] section in the php.ini without any luck. I tried mod_fastcgi but could'n get it to work at all, I also tried mod_simple_host but could get it handle php. I managed to get it working by copying my PHP install to another dir (and changing the doc_root value) and adding a cgi.assign pointing to that install in my vhost. But this is a really hackish way, it means having one PHP install for each virtualhost. Note that I'm working on a development machine running Windows, this is not a production server, I just wanted to emulate the final Server config locally to test some changes. I googled a lot this problem but all I can find are people installing Lighty on windows with mod_cgi, or installing Lighty on Windows with virtual hosts, but I never found anyone who managed to get both.

  • Practical way of keeping up-to-date backup servers?

    - by ftkg
    What is the approach generally used when you want to have backup physical servers? Currently I have a Linux server running a database, a samba share, a webapp and some scripts; and a Windows Server, running some third-party software. What I would like was to be able to have a ready backup server to enter in production in case of failure, but how to keep them up-to-date? I've seen some expensive solutions for Windows; for Linux I've wondered if I really have to build an array of scripts.
