  • Can't run install MySQL gem Fedora 14, even after installing mysql-devel, ruby-devel, and rubygems

    - by jonderry
    I'm trying to install the mysql gem via sudo gem install mysql --version 2.7 However, I get the following error: Building native extensions. This could take a while... ...........

  • How do I enable spell checking within an NSTextField on Mac OS X?

    - by Luke
    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. Thank you.

  • Why cast null before checking if object is equal to null?

    - by jacerhea
    I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

  • Is a clear and replace more efficient than a loop checking all records?

    - by Matt
    I have a C# List, that is filled from a database.. So far its only 1400 records, but I expect it to grow a LOT.. Routinely I do a check for new data on the entire list.. What I'm trying to figure out is this, is it faster to simply clear the List and reload all the data from the table, or would checking each record be faster.. Intuition tells me that the dump and load method would be faster, but I thought I should check first...

  • How can I test email generating without creating and checking 1,000 addresses?

    - by twpc
    I am working on generating emails using Java. I would love to use some sort of system where I can send out mass emails and ensure that the emails were received by the intended recipient (A. My code to send the emails worked and B.The emails were not marked as spam). How can I do this without setting up (and keeping track of) a couple hundred email addresses and then checking each one individually? Thanks!

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • Solaris cc segfaults when compiling rsync on intel platform

    I am trying to compile rsync-3.0.7 on Solaris 5.10 on an Intel chipset. When running ./configure I see the following (obviously erroneous lines): checking size of int... 0 checking size of long... 0 checking size of long long... 0 checking size of short... 0 checking size of int16_t... 0 checking size of uint16_t... 0 In config.log I see the following lines: configure.sh:5448: /tool/sunstudio12.1/bin/cc -xc99=all -o conftest -g -DHAVE_CONFIG_H conftest.c >&5 "conftest.c", line 123: warning: statement not reached cc: Fatal error in cc : Segmentation Fault configure.sh:5448: $? = 1 configure.sh: program exited with status 1 Segmentation fault? What could be causing a simple test script to segfault during compilation?

  • How to prevent Spell checking code in MS Office?

    - by Aaron
    We use MS Office. Outlook for emails, Word for some documentation and I use OneNote a lot for my own note taking. What bugs me is when I drop some code or use key words or even camel case into these apps the spell checking picks them up and I have red squiggles everywhere. Ignore is pretty much useless, so either I have to turn off Spell Check altogether start adding these to the custom dictionary. What would be good is if I can use the Set Language function to mark a whole block of text to just not be spell checked. Has anyone found a nice solution to this or do you know of a blank dictionary is best to use? I found using "Mohawk" kind of does that... might just use that for now. Maybe create a macro to switch between them.

  • C# Elegant way to handle checking for an item in a collection.

    - by JL
    I've posted a code sample below. Firstly let me explain termStore.Groups in the code below is a collection of Group Objects (The exact class is irrelevant). Checking for null : if (termStore.Groups[groupName] == null) seems like a logical (clean) approach, but if the Groups collection is empty then an exception is produced. using the termStore.Groups.Contains is not an option either because this expects a strong type i.e: .Contains(Group)... not .Contains(GroupName as string) Can someone recommend a clean / generic way I can check for if an item exists in collection . Thank you.... TermStore termStore = session.TermStores.Where(ts => ts.Name == termStoreName).FirstOrDefault(); if (termStore.Groups[groupName] == null) { termStore.CreateGroup(groupName); termStore.CommitAll(); } Update: The exact class Sharepoint Taxonomy Classes. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.taxonomy.group.aspx

  • What are the repercussions of not checking existing data when adding a foreign key?

    - by scottm
    I've inherited a database that doesn't exactly strive for data integrity. I am trying to add some foreign keys to change that, but there is data in some tables that doesn't fit the constraints. Most likely, the data won't be used again so I want to know what problems I might face by leaving it there. The other option I see is to move it into some kind of table without referential constraints, just for historical purposes. So, what are the repercussions of not checking existing data? If I create a foreign key constraint on a table and don't check existing data, will all new data inserted into the table be enforced?

  • Is it possible to create a branch from a tag in TortoiseSVN without first checking out the tag from

    - by Scott Vierregger
    Our trunk directory contains about 100mb of code and we create tags from the trunk directory. Normally, this is not an issue because a tag takes up no space until you need to use it for something. Since branches are created from tags in SVN, how can I create a branch from a tag wtihout first checking out the tag? It appears I need to do a Tortoise Update from Windows Explorer to get the tag down to my local machine before I can use Tortoise Branch/Tag... to create a branch from it. This seems illogical since we don't make changes to tag folders, and it requires that I check out 100mb of code, only to create a branch, and then check out another 100mb of code in the branch folder, where the changes will actually be made. Ideally, I'd be able to create a branch directly in the repository via RepoBrowser - but I can't see an option for it there. Am I missing something?

  • OpenSSL: how to setup an OCSP server for checking third-party certificates?

    - by StackedCrooked
    I am testing the Certificate Revocation functionality of a CMTS device. This requires me to setup a OCSP responder. Since it will only be used for testing I assume that the minimal implementation provided by OpenSSL should suffice. I have extracted the a certificate from a cable modem, copied it to my PC and converted it to the PEM format. Now I want to register it in the OpenSSL OCSP database and start a server. I have completed all these steps, but when I do a client request my server invariably responds with "unknown". It seems to be completely unaware of my certificate's existence. I would greatly appreciate if anyone would be willing to have a look at my code. For your convenience, I have created a single script consisting of a sequential list of all used commands, from setting up the CA until starting the server: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/AllCommands.sh You can also find the custom config file and the certificate that I am testing with: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/ Any help would be greatly appreciated.

  • Is it normal for Java /Tomcat to keep checking for java_pid<nnnn>.hprof?

    - by Chris
    I was monitoring my JVM running Apache Tomcat 6, running on Windows, and I noticed that every 3 seconds or so the JVM process (C:\Tomcat\bin\tomcat6.exe) is polling to see whether or not C:\Tomcatcat\java_pid3748.hprof exists, where 3748 is the Windows process ID. I haven't seen write to the hprof file, just test for existence. (I'm using Sysinternals Process Monitor (procmon.exe) for this monitoring. In procmon the polling shows up as a QueryDirectory operation, which always returns Result "NO SUCH FILE".) Is this normal, or is this a potential red flag? I gather that these hprof files are generated, perhaps among other times, when you enable the -XX:+HeapDumpOnOutOfMemoryError Java flag. I haven't enabled it myself, though I guess it could be enabled somehow in the Tomcat startup scripts.

  • Does anyone know about nagios plugin that uses nmap and does port checking??

    - by Eedoh
    Hi to all. I need to monitor open and closed ports on dozens of hosts. I've found a Nagios plugin that does what I need, but I would have to use this script through nrpe. Some of the hosts are powered by linux and they all have perl installed. But some of them are Windows machines, and it's not convenient for me to install perl on every one of them. That's why I can not use this plugin. I hope that there's Nagios plugin that uses nmap, or something similar, so it could check ports on every host remotely, without installing plugins on remote hosts, only on server.

  • Did I miss anything when checking for passwords? [migrated]

    - by Keltari
    There's a bit of a story to this, so bear with me... I am looking for a new job and came across a posting for a computer forensics position. Its not really my field, but I thought I would apply anyway, just for fun. To make a longer story shorter, they want you to uncover as many passwords as you can find. I downloaded an image and dd'd it to a thumbdrive. The only thing visible was a text file, which contained a password. I knew there had to be more, so I used an undelete utility and found 2 deleted files. First there was another text file with a password - easy. The other was a .pst file which I mounted into outlook. There were some emails with passwords, as well as an email with an image. Another email has a link to a stegenography site. Obviously, there was a file hidden in the image, so I went to the website and downloaded the stegenography decoder. I had to try some of the passwords I had found to get the file to decrypt, and sure enough, there was another text file with a password. I called it a day at that point. Did I miss any other methods?

  • What's a good tool for checking from my own machine that my server is up?

    - by chico
    I'm looking for a good tool (web site or not) that I can use to do a simple check whether my web server is accessible from outside LAN (it's serving in a non-standard port). To give some context, I've gone through this problem: can't access my ip from outside. Even the tools I've found are not really working. Currently to fetch the html I serve with the online bash tool I do: curl <my ip>:<my port> \ | sed 's/&/\&amp;/g; s/</\&lt;/g; s/>/\&gt;/g; s/"/\&quot;/g; s/'"'"'/\&#39;/g' I'm looking for a simple tool that can display the html properly, or just show raw text without resorting to sed html escaping and curl.
