  • DBA Best Practices - A Blog Series: Episode 2 - Password Lists

    - by Argenis
      Digital World, Digital Locks One of the biggest digital assets that any company has is its secrets. These include passwords, key rings, certificates, and any other digital asset used to protect another asset from tampering or unauthorized access. As a DBA, you are very likely to manage some of these assets for your company - and your employer trusts you with keeping them safe. Probably one of the most important of these assets are passwords. As you well know, the can be used anywhere: for service accounts, credentials, proxies, linked servers, DTS/SSIS packages, symmetrical keys, private keys, etc., etc. Have you given some thought to what you're doing to keep these passwords safe? Are you backing them up somewhere? Who else besides you can access them? Good-Ol’ Post-It Notes Under Your Keyboard If you have a password-protected Excel sheet for your passwords, I have bad news for you: Excel's level of encryption is good for your grandma's budget spreadsheet, not for a list of enterprise passwords. I will try to summarize the main point of this best practice in one sentence: You should keep your passwords on an encrypted, access and version-controlled, backed-up, well-known shared location that every DBA on your team is aware of, and maintain copies of this password "database" on your DBA's workstations. Now I have to break down that statement to you: - Encrypted: what’s the point of saving your passwords on a file that any Windows admin with enough privileges can read? - Access controlled: This one is pretty much self-explanatory. - Version controlled: Passwords change (and I’m really hoping you do change them) and version control would allow you to track what a previous password was if the utility you’ve chosen doesn’t handle that for you. - Backed-up: You want a safe copy of the password list to be kept offline, preferably in long term storage, with relative ease of restoring. - Well-known shared location: This is critical for teams: what good is a password list if only one person in the team knows where it is? I have seen multiple examples of this that work well. They all start with an encrypted database. Certainly you could leverage SQL Server's native encryption solutions like cell encryption for this. I have found such implementations to be impractical, for the most part. Enter The World Of Utilities There are a myriad of open source/free software solutions to help you here. One of my favorites is KeePass, which creates encrypted files that can be saved to a network share, Sharepoint, etc. KeePass has UIs for most operating systems, including Windows, MacOS, iOS, Android and Windows Phone. Other solutions I've used before worth mentioning include PasswordSafe and 1Password, with the latter one being a paid solution – but wildly popular in mobile devices. There are, of course, even more "enterprise-level" solutions available from 3rd party vendors. The truth is that most of the customers that I work with don't need that level of protection of their digital assets, and something like a KeePass database on Sharepoint suits them very well. What are you doing to safeguard your passwords? Leave a comment below, and join the discussion! Cheers, -Argenis

  • Collisions and Lists

    - by user50635
    I've run into an issue that breaks my collisions. Here's my method: Gather Input Project Rectangle Check for intersection and ispassable Update The update method is built on object_position * seconds_passed * velocity * speed. Input changes velocity and is normalized if 1. This method works well with just one object comparison, however I pass a list or a for loop to the collision detector and velocity gets changed back to a non zero when the list hits an object that passes the test and the object can pass through. Any solutions would be much appreciated. Side note is there a more proper way to simulate movement?

  • Trying to Create an Enterprise Provisioning Profile--Distribution Tab is Missing

    - by El' Jocko
    I'm attempting to create an Enterprise Provisioning Profile, but the program portal isn't working the way I expect it to (based on the documentation). Here's what I'm seeing: First, I log on as the Team Agent. Second, I navigate to the Provisioning section of the program portal. According to the documentation, I should see 4 tabs at this point: Development, Distribution, History, How To. But when I do this, the Distribution tab isn't there. And without the Distribution tab, I can't create a Enterprise Provisioning Profile (or an Ad Hoc one, for that matter). I've tried contacting Apple administrative support, but they weren't able to provide any help with this. They suggested that I try the forum. :-) Just to fill in a few more details: My company has an enterprise membership in the developer program. And when I navigate to the Certificates section, there is a Distribution tab. I figure that there must be something that I've done incorrectly. Has anyone had a similar experience? Any suggestions on what to try next?

  • Fedora distribution update pop-up after fresh installation

    - by Sayan Ghosh
    Hi, We do a kickstart installation of FC-10 at our place. I am quite intimidated by the distribution update pop up that comes up after the O/S installation. I want a keyword to put into the kickstart file that would stop Fedora from intimating with an update pop-up. Is it possible to include such a switch in the kickstart OR a script that could be added to post.bash? Thanks, Sayan

  • Outlook 2007: Filter messages differently based on mailing lists

    - by Naseer
    I am part of two mailing lists, one of which is of high importance to me and should always show up in my Inbox and the other is not so important and should go to a specific folder. Sometimes both these mailing lists are in the To/CC list. In this case, I want the message to stay in my Inbox and not get moved. Is this possible with Rules and Alerts ? If not, is there a macro ?

  • I need to order a list that is dependant on another list. how to change both lists?

    - by Ben Fossen
    I have a Matlab program that generates a list x = 6.1692 8.1863 5.8092 8.2754 6.0891 the program also outputs another list aspl = 680 637 669 599 693. The two lists are on equal length and the first element in list x is related to the first element in list aspl. I need to graph the two lists but want list aspl to be in order from smallest to largest. How would I go about doing this? If I need to move the first element in aspl to position 4 in the list, then the first element of list x also needs to be moved to position 4 in list x. The numbers above are not important they are just examples, the actual program generates hundereds of numbers. for example x = 6.1692 8.1863 5.8092 8.2754 initially aspl = 680 637 669 599 693 after changing aspl to ascending order this is how x should look. x = 5.8092 8.1863 5.8092 6.1692 8.2754 aspl = 599 637 669 680 693

  • iPhone Icon file in bundle blank when building for App store distribution

    - by Boiler Bill
    I have been spinning my wheels for a couple hours on why when I build my app with my distribution cert with the device as the target the Icon.png file in the bundle is empty. If I build with my developer cert or against the simulator the Icon.png in the bundle matches the one in my project file. I have verified my Icon.png is 57X57, has no alpha channel, had extra finder attributes removed. I even took one of the Icon.png files from my first application that is in the store today, and it didn't work either. Here is the output from the build results: CopyPNGFile build/Distribution-iphoneos/myApp.app/Icon.png Icon.png cd /Users/wrbarbour/projects/myAppTWO/myApp setenv COPY_COMMAND /Developer/Library/PrivateFrameworks/DevToolsCore.framework/Resources/pbxcp setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" "/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS Build System Support.xcplugin/Contents/Resources/copypng" -compress "" /Users/wrbarbour/projects/myAppTWO/myApp/Icon.png /Users/wrbarbour/projects/myAppTWO/myApp/build/Distribution-iphoneos/myApp.app/Icon.png Can someone get me pointed in the right direction?

  • Trouble with this Python newbie exercise. Using Lists and finding if two adjacent elements are the s

    - by Sergio Tapia
    Here's what I got: # D. Given a list of numbers, return a list where # all adjacent == elements have been reduced to a single element, # so [1, 2, 2, 3] returns [1, 2, 3]. You may create a new list or # modify the passed in list. def remove_adjacent(nums): for number in nums: numberHolder = number # +++your code here+++ return I'm kind of stuck here. What can I do?

  • Random number within a range based on a normal distribution

    - by ConfusedAgain
    I'm math challenged today :( I want to generate random numbers with a range (n to m, eg 100 to 150), but instead of purely random I want the results to be based on the normal distribution. By this I mean that in general I want the numbers "clustered" around 125. I've found this random number package that seems to have a lot of what I need: http://beta.codeproject.com/KB/recipes/Random.aspx It supports a variety of random generators (include mersiene twister) and can apply the generator to a distribution. But I'm confused... if I use a normal distribution generator the random numbers are from roughly -6 to +8 (apparently the true range is float.min to float.max). How do a scale that to my required range?

  • Is there anything like memcached, but for sorted lists?

    - by depesz
    I have a situation where I could really benefit from having system like memcached, but with the ability to store (per each key) sorted list of elements, and modifying the list by addition of values. For example: something.add_to_sorted_list( 'topics_list_sorted_by_title', 1234, 'some_title') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5436, 'zzz') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5623, 'aaa') Which I then could use like this: something.get_list_size( 'topics_list_sorted_by_title' ) // returns 3 something.get_list_elements( 'topics_list_sorted_by_title', 1, 10 ) // returns: 5623, 1234, 5436 Required system would allow me to easily get items count in every array, and fetch any number of values from the array, with the assumption that the values are sorted using attached value. I hope that the description is clear. And the question is relatively simple: is there any such system?

  • Selecting item from set given distribution

    - by JH
    I have a set of X items such as {blower, mower, stove} and each item has a certain percentage of times it should be selected from the overall set {blower=25%,mower=25%,stove=75%} along with a certain distribution that these items should follow (blower should be selected more at the beginning of selection and stove more at the end). We are given a number of objects to be overall selected (ie 100) and a overall time to do this in (say 100 seconds). I was thinking of using a roulette wheel algorithm where the weights on the wheel are affected by the current distribution as a function of the elapsed time (and the allowed duration) so that simple functions could be used to determine the weight. Are there any common approaches to problems like this that anyone is aware of? Currently i have programmed something similar to this in java using functions such as x^2 (with correct normalization for the weights) to ensure that a good distribution occurs. Other suggestions or common practices would be welcome :-)

  • Why have we got so many Linux distributions? [closed]

    - by nebukadnezzar
    Pointed to from an answer to another question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers and buttons. It would still seem easier to create a sub-distribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. In my mind there are a number of problems with having so many distributions - perhaps less security/stability due to smaller group of developers, and also the confusingly vast range of choice for newcomers to Linux. Some reasons that developers might decide to fork are: Specializing on a particular topic (work-related topic - i.e. for a Hospital, etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, proprietary technology, and such So what other reasons are there that have caused so many people decided to create their own distributions? What are the thought processes that have led to this? And are these "valid" reasons - do we need so many distributions? If you can back your experiences up with references that would be great.

  • Sharepoint Server 2007 generates event log entry every 5 minutes - "The SSP Timer Job Distribution L

    - by Teevus
    I get the following error logged into the Event Log every 5 minutes: The SSP Timer Job Distribution List Import Job was not run. Reason: Logon failure: the user has not been granted the requested logon type at this computer In addition, OWSTimer.exe periodically gets into a state where its consuming almost all the CPU and only killing the process or restarting the Sharepoint services fixes it (although I'm not sure if this is a related or seperate issue). I have tried the following (based on various suggestions floating around the web), all to no avail: iisreset (no affect) Added the Sharepoint and Sharepoint Search service accounts to Log on as a batch job and Log on as a service policies in the Group Policies for the domain. I went into the Local Computer Policy on the Sharepoint server and verified that those policies had actually been applied Verified that the Sharepoint and Sharepoint Search service accounts are both in the WSS_WPG group Verified in dcomcnfg that the WSS_WPG group (and indeed the Sharepoint and Sharepoint search service accounts) has local activation rights for SPSearch. Any more suggestions would be valued. Thanks

  • CentOS 6 - YUM Local Repo - Ensure consistent package distribution

    - by Mike Purcell
    I've read a few guides outlining how to setup a local YUM repo, but none of them explicitly stated an answer to my question; If I set up a local YUM repo, does that mean that any CentOS servers which pull from said repo will never be "ahead" of the local YUM repo? I want to ensure a consistent package distribution across all my servers. Right now, when I do a yum update, even on a daily basis, the servers can be out of alignment. For example if I run YUM update on my dev server in the morning, then run YUM update on one of my production servers in the afternoon, the production server may have picked up a new version of a package that the dev server did not pick up, due to the time window between the update commands. Rather, I'd prefer that I run yum update from my dev server which has access to remote upstream yum repos, then let it sit for 2 weeks, after which I run yum update on my production servers against the local repo on my dev server.
