  • 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).

  • Is there a recommended logging path/folder for ASP.NEt applications?

    - by the-locster
    Currently we use log4net and create a new folder (usually below C:) with write and create access rights for the worker process user. Is there perhaps a standard windows folder we should or could be using such as LOCALAPPDATA? I'm guessing that LOCALAPPDATA is a bad choice in the general case because IIS users tend to be non-interactive users and thus I don't think they have the usual user folder structrues available.

  • Subversion error: Repository moved permanently to please relocate

    - by Bart S.
    I've set up subversion and apache on my server. If I browse to it through my webbrowser it works fine (http://svn.host.com/reposname). However, if I do a checkout on my machine I get the following error: Command: Checkout from http://svn.host.com/reposname, revision HEAD, Fully recursive, Externals included Error: Repository moved permanently to 'http://svn.host.com/reposname/'; please relocate I checked apache's error log, but it doesn't say anything. (it does now - see edit) My repositories are stored under: /var/www/svn/repos/ My website is stored under: /var/www/vhosts/x/... Here's the conf file for the subdomain: <Location /> DAV svn SVNParentPath /var/www/svn/repos/ AuthType Basic AuthName "Authorization Realm" AuthUserFile /var/www/svn/auth/svn.htpasswd Require valid-user </Location> Authentication works fine. Does anyone know what might be causing this? -- Edit So I restarted apache (again) and tried it again and now it give me an error message, but it doesn't really help. Anyone have an idea what it means? [Wed Mar 31 23:41:55 2010] [error] [client my.ip.he.re] Could not fetch resource information. [403, #0] [Wed Mar 31 23:41:55 2010] [error] [client my.ip.he.re] (2)No such file or directory: The URI does not contain the name of a repository. [403, #190001] -- Edit 2 If I do svn info it doesn't give anything usefull: [root@eduro eduro.nl]# svn info http://svn.domain.com/repos/ Username: username Password for 'username': svn: Repository moved permanently to 'http://svn.domain.com/repos/'; please relocate I also tried doing a local checkout (svn checkout file:///var/www/svn/repos/reposname) and that works fine (also adding / commiting works fine). So it seems is has something to do with apache. Some other information: I'm running CentOs 5.3 Plesk 9.3 Subversion, version 1.6.9 (r901367) -- Edit 3 I tried moving the repositories, but it didn't make any difference. selinux is disabled so that isn't it either. -- Edit 4 Really? Nobody :(?

  • With ARC why use @properties anymore?

    - by trapper
    In non-ARC code retained properties handily take care of memory management for you using the self.property = syntax, so we were taught to use them for practically everything. But now with ARC this memory management is no longer an issue, so does the reason for using properties evaporate? is there still any good reason (obviously other than providing public access to instance variables) to use properties anymore?

  • Remove extra junk from C preprocessor?

    - by Brendan Long
    I'm trying to use the C preprocessor on non-C code, and it works fine except for creating lines like this at the top: # 1 "test.java" # 1 "<built-in>" # 1 "<command-line>" # 1 "test.java" The problem is that these lines aren't valid in Java. Is there any way to get the preprocessor to not write this stuff? I'd prefer not to have to run this through something else to just remove the first 4 lines every time.

  • Background image not showing up on IE8

    - by Rich Bradshaw
    I've read through other questions but to no avail - I really can't work this out. The site is http://bit.ly/cqEO53 (hoping to not have any search links to this page so shortening URL). The gradient on the footer looks great in non IE browsers, but fails to show in IE 7,8 and the dev preview. Any ideas?

  • In mercurial, is there a way to disable ALL configurations (system, user, repo)?

    - by Geoffrey Zheng
    On any non-trivial hg installation, the hgrc's tend to contain significant stuff. Is there a way to completely ignore/bypass ALL configurations, from system, user, to repo-level? The use case is to use some hg core functionalities in some automation scripts. Currently, if anything is misconfigured (and I mess with my ~/.hgrc a lot), the scripts will abort for something it doesn't use at all. It'd be perfect is I can just hg <whatever> --config:none.

  • Upgrading Entity Framework 1.0 to 4.0 to include foreign keys

    - by duthiega
    Currently I've been working with Entity Framework 1.0 which is located under a service façade. Below is one of the save methods I've created to either update or insert the device in question. This currently works but, I can't help feel that its a bit of a hack having to set the referenced properties to null then re-attach them just to get an insert to work. The changedDevice already holds these values, so why do I need to assign them again. So, I thought I'll update the model to EF4. That way I can just directly access the foreign keys. However, on doing this I've found that there doesn't seem to be an easy way to add the foreign keys except by removing the entity from the diagram and re-adding it. I don't want to do this as I've already been through all the entity properties renaming them from the DB column names. Can anyone help? /// <summary> /// Saves the non network device. /// </summary> /// <param name="nonNetworkDeviceDto">The non network device dto.</param> public void SaveNonNetworkDevice(NonNetworkDeviceDto nonNetworkDeviceDto) { using (var context = new AssetNetworkEntities2()) { var changedDevice = TransformationHelper.ConvertNonNetworkDeviceDtoToEntity(nonNetworkDeviceDto); if (!nonNetworkDeviceDto.DeviceId.Equals(-1)) { var originalDevice = context.NonNetworkDevices.Include("Status").Include("NonNetworkType").FirstOrDefault( d => d.DeviceId.Equals(nonNetworkDeviceDto.DeviceId)); context.ApplyAllReferencedPropertyChanges(originalDevice, changedDevice); context.ApplyCurrentValues(originalDevice.EntityKey.EntitySetName, changedDevice); } else { var maxNetworkDevice = context.NonNetworkDevices.OrderBy("it.DeviceId DESC").First(); changedDevice.DeviceId = maxNetworkDevice.DeviceId + 1; var status = changedDevice.Status; var nonNetworkType = changedDevice.NonNetworkType; changedDevice.Status = null; changedDevice.NonNetworkType = null; context.AttachTo("DeviceStatuses", status); if (nonNetworkType != null) { context.AttachTo("NonNetworkTypes", nonNetworkType); } changedDevice.Status = status; changedDevice.NonNetworkType = nonNetworkType; context.AddToNonNetworkDevices(changedDevice); } context.SaveChanges(); } }

  • Resources for Windows Phone 7 development

    - by geocoin
    Windows Phone 7 has just been unveiled and right now there is no publicly available information to non-privileged developers/partners. MS are announcing all details of the development chain at the Mix10 conference. So until then this could be a good starting point/collection of online resources as they appear EDIT: I've added the speculation tag so we can also accumulate speculation. Please mark speculative posts as such. once firm details are announced we can confirm or delete them

  • Can anyone help with this Magento error?

    - by Duane
    Fatal error: Call to a member function getArea() on a non-object in {directory}/includes/src/Mage_Core_Model_App_Area.php on line 155 Cropped up when I installed an extension that I wrote on a clean install of Magento. When ported to the dev server it took it down and I cant seem to find where it has originated. Disabling the extension changes nothing. Along with clearing the cache and all the regular Magento hiccups. I've ensured that file permissions are correct to the best of my knowledge.

  • R: preventing unlist to drop NULL values

    - by nico
    I'm running into a strange problem. I have a vector of lists and I use unlist on them. Some of the elements in the vectors are NULL and unlist seems to be dropping them. How can I prevent this? Here's a simple (non) working example showing this unwanted feature of unlist a = c(list("p1"=2, "p2"=5), list("p1"=3, "p2"=4), list("p1"=NULL, "p2"=NULL), list("p1"=4, "p2"=5)) unlist(a) p1 p2 p1 p2 p1 p2 2 5 3 4 4 5

  • Fixing Floating Point Error

    - by HannesNZ
    I have some code that gets the leading value (non-zero) of a Double using normal math instead of String Math... For Example: 0.020 would return 2 3.12 would return 3 1000 should return 1 The code I have at the moment is: LeadingValue := Trunc(ResultValue * Power(10, -(Floor(Log10(ResultValue))))) However when ResultValue is 1000 then LeadingValue ends up as 0. What can I do to fix this problem I'm assuming is being caused by floating point errors? Thanks.

  • Emacs, Linux and international keyboard layouts

    - by sabof
    Is there an easy way to use emacs key-bindings when you are using a not-English (Russian) keyboard layout? Whenever an international layout is on, all keystrokes are interpreted literally, M-? instead of M-a. As a result I can't use commands. It would also be nice if Linux could interpret non-prefixed and shift-prefixed keys according according to an international layout, while keeping the rest English.

  • Bipartite matching in Python

    - by vailen
    Does anybody know any module in Python that computes the best bipartite matching? I have tried the following two: munkres hungarian However, in my case, I have to deal with non-complete graph (i.e., there might not be an edge between two nodes), and therefore, there might not be a match if the node has no edge. The above two packages seem not to be able to deal with this. Any advice?

    Just like using the many twitter or facebook widgets out there that pull the feed and display it in a nice widget, I want to create a "widget" that pulls a feed from a wordpress blog that I have, and displays it on a static, non-wordpress page. Before I try getting my hands dirty with jquery, do you know if there is any pre-existing code or plugins out there that I can use?
