  • The challenge of giving a positive No

    - by MarkPearl
    I find it ironic that the more I am involved in the software industry, the more apparent it becomes that soft skills are just as if not more important than the technical abilities of a developer. One of the biggest challenges I have faced in my career is in managing client expectations to what one can deliver and being able to work with multiple clients. If I look at where things commonly go pear shaped, one area features a lot is where I should have said "No" to a request, but because of the way the request was made I ended up saying yes. Time and time again this has caused immense pain. Thus, when I saw on Amazon that they had a book titled "The power of a positive no" by William Ury I had to buy it and read it. In William's book he explains an approach to saying No that while extremely simple does change the way a No is presented. In essence he talks of a pattern the Yes! > No > Yes? Pattern. 1. Yes! -> positively and concretely describing your core interests and values 2. No. -> explicitly link your no to this YES! 3. Yes? -> suggest another positive outcome or agreement to the other person Let me explain how I understood it. If you are working on a really important project and someone asks you to do add a quick feature to another project, your Yes! would be to the more important project, which would mean a No to the quick feature, and an option for your Yes? may be an alternative time when you can look at it.. An example of an appropriate response would be... It is really important that I keep to the commitment that I made to this customer to finish his project on time so I cannot work on your feature right now but I am available to help you in a weeks time. William then goes on to explain the type of behaviour a person may display when the no is received. He illustrates this with a diagram called the curve of acceptance. William points out that if you are aware of the type of behaviour you can expect it empowers you to stay true to your no. Personally I think reading and having an understanding of the “soft” side of things like saying no is invaluable to a developer.

  • Ubuntu won't suspend automatically any more

    - by Sparhawk
    In the last month or so, Ubuntu (12.04) has stopped sleeping automatically. I've gone to System Settings Power, and verified (and toggled) "suspend on inactive for" to 5 minutes (for both battery and "when plugged in"), but the system stays awake. I've also tried used code similar to $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 300 $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 300 to set the timeout values. I've also verified these in dconf Editor. Previously, I could set this quite low to make my computer sleep quickly, but now it no longer works either. I'm not sure if this is relevant, but under old versions of Ubuntu, if I wanted my computer to never suspend (via the CLI), I would also have to set $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac false At some point, this seemed to have been depreciated (and also gave me the error "No such key 'sleep-inactive-ac'"). I found that it it was enough to set sleep-inactive-ac-timeout to 0. This worked for a while, but at some point auto-suspend stopped working as stated above. Oddly enough, the sleep-inactive-ac key is still present when I look via dconf editor. However, when I click it, it says "no schema", and the summary, etc. fields are blank. To test if the dconf power plugin was working, I tried playing around with other settings in the schema. Idle-dim-time and idle-dim-ac work as expected . However, setting sleep-display-ac to 5 seconds has no effect. I'm also not sure if this is relevant, but I've uninstalled gnome-screensaver, and installed xscreensaver. I have tried killing xscreensaver and re-installing gnome-screensaver, but this did not help. I've also had some trouble with DPMS. I'm not sure if this is related, but I'll put the information here, just in case. Using xscreensaver, I set Power Management to enabled, with standby and suspend timeouts to 10 minutes. I've verified these settings in ~/.xscreensaver and xset q. However, the screen blanks after about 30 seconds. If I turn off DPMS (either via xscreensaver GUI or modifying ~/.xscreensaver), it won't blank at all, so I know that DPMS is partially reading the xscreensaver settings. -- edit I've attempted more troubleshooting, by creating a new user account, then logging out of the main account and into the new account. I've tried modifying the timeouts via dconf, but get the same results as above (i.e. it doesn't work, nor does sleep-display-ac, but idle-dim-time and idle-dim-ac work). Also, the depreciated sleep-display-ac key is not visible, so I think that this is probably unrelated. -- edit I've since moved to gnome-shell instead of unity, and still have this problem, so I guess that it's something to do with gnome-power-manager.

  • 24HOP gets off to a good start

    - by Rob Farley
    Session 11 is on as I write this – Ami Levin presenting about Primary Keys. It’s a good session. But actually, they’ve all been excellent so far, not just Ami’s. I’ve heard only good things about the content. So if you’re reading this and 24HOP is still on, then tune in and take part. If it’s finished, get yourself over to http://sqlpass.org/24hours and see if the sessions have been made available on-demand. Yes – you should be able to watch the sessions when you want to for a year. Watching live is best, because you can ask questions and have them answered during the session, but if there are ones you just couldn’t make, then watching them on-demand is a good option. Numbers have been “not bad”. At the moment it’s still the middle of the night for most Americans – about 6:30am in New York, and yet we’ve had well over a hundred at all the sessions so far, getting up to well over 300 for some sessions. And when I look through the list of names, I see a bunch of names that suggest we’re reaching people from all around the world. I’m seriously looking forward to seeing the stats about which countries have been represented in the audiences. There have been a few comments about the platform. Everyone seems to consider IBTalk an improvement on LiveMeeting, but the closed captioning has met a mixed reception. Some people are loving it, whereas other people are finding the translations leave quite a bit of space for improvement. If you have feedback on this, please feel free to drop me an email (my name with an underscore at hotmail.com, or with a dot at sqlpass.org should reach me just fine, or Twitter, etc). I don’t know how many of the sessions I’ll get to watch overnight – but I’m looking forward to seeing how things go as the day progresses. Big thanks to everyone who’s involved – the sponsors, PASS HQ team and the IBTalk folk who have stayed up overnight to facilitate, plus the moderators, the people doing the live captioning, and of course the speakers and attendees. I love how the SQL Community gets behind things like this. Earlier, the Adelaide SQL Server User Group gathered and watched Denny Lee’s session on BigData, and everyone in the group agreed that it worked really well. I took a picture of our cinema room, although you could only see a small section of the audience. @rob_farley

  • SQL SERVER – Fix: Error: 10920 Cannot drop user-defined function. It is being used as a resource governor classifier

    - by pinaldave
    If you have not read my SQL SERVER – Simple Example to Configure Resource Governor – Introduction to Resource Governor yesterday’s detailed primer on Resource Governor, I suggest you go ahead and read it before continuing this article. After reading the article the very first email I received was as follows: “Pinal, I configured resource governor on my development server and it worked fine with tests I ran. After doing some tests, I decided to remove the resource governor and as a first step I disabled it however, I was not able to drop the classification function during the process of the clean up. It was continuously giving me following error. Msg 10920, Level 16, State 1, Line 1 Cannot drop user-defined function myudfname. It is being used as a resource governor classifier. Would you please give me solution?” The original email was really this short and there is no other information. I am glad he has done experiments on development server and not on the production server. Production server must not be the playground of the experiments. I think I have covered the answer of this error in an earlier blog post. If the user disables the Resource Governor it is still not possible to drop the function because it can be enabled again and when enabled it can still use the same function. Here is the simple resolution of the how one can drop the classifier function (do this only if you are not going to use the function). The reason the classifier function can’t be dropped because it is associated with resource governor. Create a new classified function for your resource governor or just assign NULL as described in the following T-SQL Script and you will be able to drop the function without error. ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION = NULL) GO ALTER RESOURCE GOVERNOR DISABLE GO DROP FUNCTION dbo.UDFClassifier GO I am glad that user asked me question instead of doing something radically different, which can leave the server in the unusable state. I am aware of this only method to avoid this error. Is there any better way to achieve the same?

  • Preview Links and Images in Google Chrome

    - by Asian Angel
    Anyone who has used the CoolPreviews extension in Firefox knows how wonderful that preview window can be. Now you can get the same kind of functionality in Chrome with the ezLinkPreview extension. Note: Extension will not work on websites containing “frame buster” code (navigation to the actual URL will occur). Before Normally if you want to have a better look at a particular webpage the only option you have is to go ahead and open it in a new tab or window. But it would certainly be nice to be able to take a quick “sneak peek” before-hand… After As soon as you have finished installing the extension everything is ready to go…just refresh any pages open prior to installation and enjoy the preview goodness. When you hover your mouse near any link you will notice a small “Preview Button” appear with the letters “EZ” inside. A closer look at the “Preview Button”. Click on the “Preview Button” to open the popup window. Now you can get a very good idea of whether the page is worth visiting or not. Here is a closer look at the popup window. Notice that you can see the URL for the webpage and access a convenient set of buttons on the right side (Open to new tab, Pin to keep overlay open, and Close). You can even resize the window as desired to best suit your needs (you can actually grab any of the four corners to resize the popup window). It is also possible to open a “preview window” inside the popup window…you can see the “Preview Button” here… If you have Chrome maximized you can enjoy using a large sized “preview window”. Now that is nice! For those who may be curious you can see that ezLinkPreview works nicely with images too. Conclusion The ezLinkPreview extension provides a quick and simple way to preview links and/or images while you are browsing. If you are looking for similar functionality in Firefox then be sure to read our article on CoolPreviews here.

  • Use CSS Selectors with HtmlUnit

    - by kerry
    HtmlUnit is a great library for performing web integration tests in Java.  But sometimes node traversal can be somewhat cumbersome. Fear not fellow automated tester (good for you!).  I found a great little project on Github that will allow you to query your document for elements via css selectors similar to jQuery. The project is located at https://github.com/chrsan/css-selectors.  You can use Maven to build it, or download 1.0.2 here.  Beware.  I will not be updating this link so I suggest you download the latest code. In any case, you can use it like so: // from HtmlUnit getting started final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net"); final DOMNodeSelector cssSelector = new DOMNodeSelector(page.getDocumentElement()); final Set elements = cssSelector.querySelectorAll("div.section h2"); final Node first = elements.iterator().next(); assertThat(first.getTextContent(), equalTo("HtmlUnit")); The only problem here is that the querySelectAll returns a Set<Node>.  Not HtmlElement like we may want in some cases.   However, if you were to reflect on the Set, you would find that it is indeed a Set of HtmlElement objects. Typically, I like to create a base class for my web tests.  Just for fun, I am using the $ method similar to jQuery. public class WebTestBase { protected WebClient webClient; protected HtmlPage htmlPage; protected void goTo(final String url){ return (HtmlPage)webClient.getPage(url); } protected List $(final String cssSelector) { final DOMNodeSelector cssSelector = new DOMNodeSelector(htmlPage.getDocumentElement()); final Set nodes = cssSelector.querySelectorAll("div.section h2"); // for some reason Set cannot be cast to Set? final List elements = new ArrayList(nodes.size()); for (final Node node : nodes) { elements.add((HtmlElement)node); } return elements; } } Now we can write tests like this: public class LoginWebTest extends WebTestBase { @Test public void login_page_has_instructions() throws Exception { goTo(baseUrl + "/login") assertThat( $("p.instructions").size(), equalTo(1) ); } }

  • Stop YouTube Videos from Automatically Playing in Chrome

    - by The Geek
    If you’ve actually used the internet before, you’ve probably come across a page with an auto-playing YouTube clip, and chances are good it was a rather annoying one. Here’s how to stop them from starting automatically in Chrome. We’ve already told you how to stop them from automatically playing if you’re a Firefox user (best answer: use Flashblock!), but now it’s time for Chrome users to get their turn. Use the Stop Autoplay for YouTube Extension The great thing about this extension is that it stops the video from playing, but it allows it to continue buffering, so when you do feel like playing the video, it’ll already be downloaded—really useful for people with slower internet connections. There’s no UI or anything fancy, just head to the extension page and click the Install button. If you want to get rid of it later, use the Tools –> Extensions menu (or you can type chrome://extensions/ into your address bar), and then click the Uninstall link for that add-on.   Download Stop Autoplay for YouTube [Google Chrome Extensions] Using FlashBlock for Chrome If you really wanted to, you could just disable Flash across the board using FlashBlock for Chrome. Once you’ve installed the extension, you won’t see any Flash elements anywhere, and you’ll have to move your mouse over them and click to enable them each time. When I installed the extension the first time, I noticed that YouTube was already in the allow list. I’m not sure if that’s the default setting or not, but you can use the icon in the address bar, or the Options from the Extensions panel to get to the settings page, and from there you can remove anything from the White List that you wouldn’t want. Another nice feature about Flash Block is that it can also block Silverlight, or you could simply uninstall or remove unnecessary Chrome plug-ins.

  • Is reliance on parametrized queries the only way to protect against SQL injection?

    - by Chris Walton
    All I have seen on SQL injection attacks seems to suggest that parametrized queries, particularly ones in stored procedures, are the only way to protect against such attacks. While I was working (back in the Dark Ages) stored procedures were viewed as poor practice, mainly because they were seen as less maintainable; less testable; highly coupled; and locked a system into one vendor; (this question covers some other reasons). Although when I was working, projects were virtually unaware of the possibility of such attacks; various rules were adopted to secure the database against corruption of various sorts. These rules can be summarised as: No client/application had direct access to the database tables. All accesses to all tables were through views (and all the updates to the base tables were done through triggers). All data items had a domain specified. No data item was permitted to be nullable - this had implications that had the DBAs grinding their teeth on occasion; but was enforced. Roles and permissions were set up appropriately - for instance, a restricted role to give only views the right to change the data. So is a set of (enforced) rules such as this (though not necessarily this particular set) an appropriate alternative to parametrized queries in preventing SQL injection attacks? If not, why not? Can a database be secured against such attacks by database (only) specific measures? EDIT Emphasis of the question changed slightly, in the light of the initial responses received. Base question unchanged. EDIT2 The approach of relying on paramaterized queries seems to be only a peripheral step in defense against attacks on systems. It seems to me that more fundamental defenses are both desirable, and may render reliance on such queries not necessary, or less critical, even to defend specifically against injection attacks. The approach implicit in my question was based on "armouring" the database and I had no idea whether it was a viable option. Further research has suggested that there are such approaches. I have found the following sources that provide some pointers to this type of approach: http://database-programmer.blogspot.com http://thehelsinkideclaration.blogspot.com The principle features I have taken from these sources is: An extensive data dictionary, combined with an extensive security data dictionary Generation of triggers, queries and constraints from the data dictionary Minimize Code and maximize data While the answers I have had so far are very useful and point out difficulties arising from disregarding paramaterized queries, ultimately they do not answer my original question(s) (now emphasised in bold).

  • MOSS 2007 WSP Retraction 'Error"

    - by juanlarios
    This one is a quick post , but I thought I would post this information as I could not find anything that helped me on this specific scenario. Please read the entire article before taking action as there are some irreversable or very troublesome routes I caution about! Problem: I had a client trying to retract a WSP from Central Admin and would eventually go to an, 'Error' State. I could not retract it and after looking at event logs I figured it was a problem with security. I tried several accounts, checked the databases to see if there was some issue with readonly databases and nothing was working.   Solution: Delete the solution from central admin! Yes, I said it. With StsAdm , just delete the solution from Central Admin using this command: "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN\STSADM.exe" -o deletesolution -name "yoursolution.wsp" What has just happened is that Central Admin does not know about the WSP anymore but the feature and any deployed files are still on the server. For whatever reason SharePoint was not able to retract the files as it normally does. Now you can do one of two things, you can add the solution again to central admin and deploy overtop of the deployed files so it overrides them, or simply clean up the files manually. I re-added the solution through stsadm, but then deployed through stsadm using the -force option in the command. This overrides the existing files on the server. If you deploy through Central admin it will tell you you need the -force option that is not offered as part of the UI in central admin. Use the following command: "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN\STSADM.exe" -o deploysolution -name "YourSolution.wsp" -immediate -allowgacdeployment -force Just to make sure everything was good, I retracted to solution again, and it worked! then I deleted the solution from central admin alltogether. Then I checked the server and noticed all the files that were deployed with the WSP were cleaned up properly. I then re-added the new WSP the client was looking to install (an Updated WSP). Conclusion: I have no idea why it was not able to retract, but I have seen this several times. I don't know if has to do with security of certain accounts. Althought it's anoying at times, it is fairly easy to fix if you have good instructions. Hope it helps you out!   ***WORD OF CAUTION - if you clean up the files manually you might want to uninstall the features through STSADM commands as SharePOint might still recognize the features that were deployed as the WSP. You might not want to get into the mess of deleting files that are still part of activated or installed Features. THis is why I suggest doing what I did.

  • Why CoffeeScript is tough to maintain

    - by Renso
    I recently started trying out CoffeeScript only to find out that it caused more headaches. The abstraction level of jQuery was perfect, it did not dictate to coders how to design their code, it just works. However, I recently posted a request to the CoffeeScript team to consider introducing curly braces to help with more complex code to control the flow of logic. For example a if-then-else with many nested levels can be near impossible to debug without tracing through it when using CoffeeScript. Also with IDEs like Visual Studio, regular JavaScript intellicense and auto-formatting make it easy to appropriate indent nested levels without any work on the part of the developer and reading it is not that hard, especially with some extensions that show vertical lines in the code editor to help see what is nested within what part of the code.However with CoffeeScript that is not the case. The samples given in the CoffeeScript web site are of course just simple examples to explain the features and one gets excited pretty quick over the powerful shortcuts. I tried to convert a piece of JavaScript over to CoffeeScript and gave up since you need to first of all remove ALL non CoffeeScript coding constructs for it to even compile. However js2coffee can help with that. However to keep track of nested levels became something that was simply not manageable using CoffeeScript.Furthermore, any coding language that controls the flow of logic by indentation is extremely dangerous for obvious reasons. I liked CoffeeScript a lot, but the fact that the logical flow of the code is controlled by how much you indent code, spaces or tabs, is not reliable as there is no way the programmer has an easy way of knowing what parts of the code will get hit when the code spans a page.When I suggested introducing curly braces in CoffeeScript the team, one contributor advised me that my code needs to be re-designed! Needless to say that is absurd. When I included a piece of the code he asked my if it was legacy code. It's like saying to a Java programmer, sorry you cannot use Java because we don't agree with how you write your code.jashkenas from the CoffeeScript blog gave some great suggestions and made the point that introducing curly braces would be very problematic for them as they use them to denote objects. Makes sense, but I would still love to see some way to replace code flow control with spaces and indentation to something more concrete and human readable.

  • Media server...serving files...............for a limited time only

    - by Craig
    I’m new to Ubuntu and am seeking help with a media server I have built. I have a couple of HTPCs in my house running XBMC. I wanted to build one for the family room working double duty as a HTPC, and media server to share movies, TV shows, music, etc. on my Windows network. So using some spare old parts I had lying around I decided to go CRAZY and build my first Linux box. I used Ubuntu because it seemed to be the most user friendly variant, especially for people that are new to Linux. I had to do a few things to get the media files shared properly on my network: Made sure my two media drives auto-mount every time I boot the computer by editing the “fstab” file – “sudo nano /etc/fstab” Installed Samba - “sudo apt-get install samba” Set a password for Samba - “sudo smbpasswd –a USERNAME” Edited the Samba configuration file to make sure the computer was in my networks workgroup – “sudo nano /etc/samba/smb.conf” In the file manager (not sure if that’s the right name for it), I right-clicked my media folders and set the sharing and permissions. The sharing was done without guest access, and permissions were set to; Owner, Group, and Others - Access: Create and Delete Files. Adjusted the Power Management settings to never put the system into sleep mode. I checked to see if I had access to the files from a Windows 7 machine and I did (Woo Hoo!). But when I tried to play any of my video files from the Windows machine (using VLC media player), they would only play for about 2-5 minutes and then they would stop with an error message saying that the file could not be accessed (Booo...). I tried playing some files through XBMC running in Windows and they worked for a bit longer (about 10-15mins), but they also stopped playing. I installed the Linux version of XBMC on the server and played the files locally with no problems. It doesn’t seem to be an issue with the files themselves, it seems to be a sharing problem on my network. So my question to the Ubuntu gurus out there is: Did I miss adding/editing something in the Samba configuration file? Did I use the right method to share my media files (file manager vs. using the terminal)? Is it possible for the computer to still go to sleep without the screen going black (does that even make sense?). Are there any special settings in Ubuntu that I should be using since this computer as a media server (is there a media server mode?...!...?). Any help on this matter would be greatly appreciated. Thanks

  • Using a SQL Prompt snippet with template parameters

    - by SQLDev
    As part of my product management role I regularly attend trade shows and man the Red Gate booth in the vendor exhibition hall. Amongst other things this involves giving product demos to customers. Our latest demo involves SQL Source Control and SQL Test in a continuous integration environment. In order to demonstrate quite how easy it is to set up our tools from scratch we start the demo by creating an entirely new database to link to source control, using an individual database name for each conference attendee. In SQL Server Management Studio this can be done either by selecting New Database from the Object Explorer or by executing “CREATE DATABASE DemoDB_John” in a query window. We recently extended the demo to include SQL Test. This uses an open source SQL Server unit testing framework called tSQLt (www.tsqlt.org), which has a CLR object that requires EXTERNAL_ACCESS to be set as follows: ALTER DATABASE DemoDB_John SET TRUSTWORTHY ON This isn’t hard to do, but if you’re giving demo after demo, this two-step process soon becomes tedious. This is where SQL Prompt snippets come into their own. I can create a snippet named create_demo_db for this following: CREATE DATABASE DemoDB_John GO USE DemoDB_John GO ALTER DATABASE DemoDB_John SET TRUSTWORTHY ON Now I just have to type the first few characters of the snippet name, select the snippet from SQL Prompt’s candidate list, and execute the code. Simple! The problem is that this can only work once due to the hard-coded database name. Luckily I can leverage a nice feature in SQL Server Management Studio called Template Parameters. If I modify my snippet to be: CREATE DATABASE <DBName,, DemoDB_> GO USE <DBName,, DemoDB_> GO ALTER DATABASE <DBName,, DemoDB_> SET TRUSTWORTHY ON Once I’ve invoked the snippet, I can press Ctrl-Shift-M, which calls up the Specify Values for Template Parameters dialog, where I can type in my database name just once. Now you can click OK and run the query. Easy. Ideally I’d like for SQL Prompt to auto-invoke the Template Parameter dialog for all snippets where it detects the angled bracket syntax, but typing in the keyboard shortcut is a small price to pay for the time savings.

  • Learn programming backwards, or "so I failed the FizzBuzz test. Now what?"

    - by moraleida
    A Little Background I'm 28 today, and I've never had any formal training in software development, but I do have two higher education degrees equivalent to a B.A in Public Relations and an Executive MBA focused on Project Management. I've worked on those fields for about 6 years total an then, 2,5 years ago I quit/lost my job and decided to shift directions. After a month thinking things through I decided to start freelancing developing small websites in WordPress. I self-learned my way into it and today I can say I run a humble but successful career developing themes and plugins from scratch for my clients - mostly agencies outsourcing some of their dev work for medium/large websites. But sometimes I just feel that not having studied enough math, or not having a formal understanding of things really holds me behind when I have to compete or work with more experienced developers. I'm constantly looking for ways to learn more but I seem to lack the basics. Unfortunately, spending 4 more years in Computer Science is not an option right now, so I'm trying to learn all I can from books and online resources. This method is never going to have NASA employ me but I really don't care right now. My goal is to first pass the bar and to be able to call myself a real programmer. I'm currently spending my spare time studying Java For Programmers (to get a hold on a language everyone says is difficult/demanding), reading excerpts of Code Complete (to get hold of best practices) and also Code: The Hidden Language of Computer Hardware and Software (to grasp the inner workings of computers). TL;DR So, my current situation is this: I'm basically capable of writing any complete system in PHP (with the help of Google and a few books), integrating Ajax, SQL and whatnot, and maybe a little slower than an experienced dev would expect due to all the research involved. But I was stranded yesterday trying to figure out (not Google) a solution for the FizzBuzz test because I didn't have the if($n1 % $n2 == 0) method modulus operator memorized. What would you suggest as a good way to solve this dilemma? What subjects/books should I study that would get me solving problems faster and maybe more "in a programmers way"? EDIT - Seems that there was some confusion about what did I not know to solve FizzBuzz. Maybe I didn't express myself right: I knew the steps needed to solve the problem. What I didn't memorize was the modulus operator. The problem was in transposing basic math to the program, not in knowing basic math. I took the test for fun, after reading about it on Coding Horror. I just decided it was a good base-comparison line between me and formally-trained devs. I just used this as an example of how not having dealt with math in a computer environment before makes me lose time looking up basic things like modulus operators to be able to solve simple problems.

  • Encrypting your SQL Server Passwords in Powershell

    - by laerte
    A couple of months ago, a friend of mine who is now bewitched by the seemingly supernatural abilities of Powershell (+1 for the team) asked me what, initially, appeared to be a trivial question: "Laerte, I do not have the luxury of being able to work with my SQL servers through Windows Authentication, and I need a way to automatically pass my username and password. How would you suggest I do this?" Given that I knew he, like me, was using the SQLPSX modules (an open source project created by Chad Miller; a fantastic library of reusable functions and PowerShell scripts), I merrily replied, "Simply pass the Username and Password in SQLPSX functions". He rather pointed responded: "My friend, I might as well pass: Username-'Me'-password 'NowEverybodyKnowsMyPassword'" As I do have the pleasure of working with Windows Authentication, I had not really thought this situation though yet (and thank goodness I only revealed my temporary ignorance to a friend, and the embarrassment was minimized). After discussing this puzzle with Chad Miller, he showed me some code for saving passwords on SQL Server Tables, which he had demo'd in his Powershell ETL session at Tampa SQL Saturday (and you can download the scripts from here). The solution seemed to be pretty much ready to go, so I showed it to my Authentication-impoverished friend, only to discover that we were only half-way there: "That's almost what I want, but the details need to be stored in my local txt file, together with the names of the servers that I'll actually use the Powershell scripts on. Something like: Server1,UserName,Password Server2,UserName,Password" I thought about it for just a few milliseconds (Ha! Of course I'm not telling you how long it actually took me, I have to do my own marketing, after all) and the solution was finally ready. First , we have to download Library-StringCripto (with many thanks to Steven Hystad), which is composed of two functions: One for encryption and other for decryption, both of which are used to manage the password. If you want to know more about the library, you can see more details in the help functions. Next, we have to create a txt file with your encrypted passwords:$ServerName = "Server1" $UserName = "Login1" $Password = "Senha1" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ServersSecurePassword.txt -Append $ServerName = "Server2" $UserName = "Login2" $Password = "senha2" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ ServersSecurePassword.txt -Append .And in the c:\temp\ServersSecurePassword.txt file which we've just created, you will find your Username and Password, all neatly encrypted. Let's take a look at what the txt looks like: .and in case you're wondering, Server names, Usernames and Passwords are all separated by commas. Decryption is actually much more simple:Read-EncryptedString -InputString $EncryptString -password "YourPassword" (Just remember that the Password you're trying to decrypt must be exactly the same as the encrypted phrase.) Finally, just to show you how smooth this solution is, let's say I want to use the Invoke-DBMaint function from SQLPSX to perform a checkdb on a system database: it's just a case of split, decrypt and be happy!Get-Content c:\temp\ServerSecurePassword.txt | foreach { [array] $Split = ($_).split(",") Invoke-DBMaint -server $($Split[0]) -UserName (Read-EncryptedString -InputString $Split[1] -password "YourPassword" ) -Password (Read-EncryptedString -InputString $Split[2] -password "YourPassword" ) -Databases "SYSTEM" -Action "CHECK_DB" -ReportOn c:\Temp } This is why I love Powershell.

  • Stencil buffer appears to not be decrementing values correctly

    - by Alex Ames
    I'm attempting to use the stencil buffer as a clipper for my UI system, but I'm having trouble debugging a problem I'm running in to. This is what I'm doing: A widget can pass a rectangle to the the stencil clipper functions, which will increment the stencil buffer values that it covers. Then it will draw its children, which will only get drawn in the stencilled area (so that if they extend outside they'll be clipped). After a widget is done drawing its children, it pops that rectangle from the stack and in the process decrements the values in the stencil buffer that it has previously incremented. The slightly simplified code is below: static void drawStencil(Rect& rect, unsigned int ref) { // Save previous values of the color and depth masks GLboolean colorMask[4]; GLboolean depthMask; glGetBooleanv(GL_COLOR_WRITEMASK, colorMask); glGetBooleanv(GL_DEPTH_WRITEMASK, &depthMask); // Turn off drawing glColorMask(0, 0, 0, 0); glDepthMask(0); // Draw vertices here ... // Turn everything back on glColorMask(colorMask[0], colorMask[1], colorMask[2], colorMask[3]); glDepthMask(depthMask); // Only render pixels in areas where the stencil buffer value == ref glStencilFunc(GL_EQUAL, ref, 0xFF); glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP); } void pushScissor(Rect rect) { // increment things only at the current stencil stack level glStencilFunc(GL_EQUAL, s_scissorStack.size(), 0xFF); glStencilOp(GL_KEEP, GL_INCR, GL_INCR); s_scissorStack.push_back(rect); drawStencil(rect, states, s_ScissorStack.size()); } void popScissor() { // undo what was done in the previous push, // decrement things only at the current stencil stack level glStencilFunc(GL_EQUAL, s_scissorStack.size(), 0xFF); glStencilOp(GL_KEEP, GL_DECR, GL_DECR); Rect rect = s_scissorStack.back(); s_scissorStack.pop_back(); drawStencil(rect, states, s_scissorStack.size()); } And this is how it's being used by the Widgets if (m_clip) pushScissor(m_rect); drawInternal(target, states); for (auto child : m_children) target.draw(*child, states); if (m_clip) popScissor(); This is the result of the above code: There are two things on the screen, a giant test button, and a window with some buttons and text areas on it. The text area scroll box is set to clip its children (so that the text doesn't extend outside the scroll box). The button is drawn after the window and should be on top of it completely. However, for some reason the text area is appearing on top of the button. The only reason I can think of that this would happen is if the stencil values were not getting decremented in the pop, and when it comes time to render the button, since those pixels don't have the right stencil value it doesn't draw over. But I can't figure out whats wrong with my code that would cause that to happen.

  • How to get tens of millions of pages indexed by Google bot?

    - by Chris Adragna
    We are currently developing a site that currently has 8 million unique pages that will grow to about 20 million right away, and eventually to about 50 million or more. Before you criticize... Yes, it provides unique, useful content. We continually process raw data from public records and by doing some data scrubbing, entity rollups, and relationship mapping, we've been able to generate quality content, developing a site that's quite useful and also unique, in part due to the breadth of the data. It's PR is 0 (new domain, no links), and we're getting spidered at a rate of about 500 pages per day, putting us at about 30,000 pages indexed thus far. At this rate, it would take over 400 years to index all of our data. I have two questions: Is the rate of the indexing directly correlated to PR, and by that I mean is it correlated enough that by purchasing an old domain with good PR will get us to a workable indexing rate (in the neighborhood of 100,000 pages per day). Are there any SEO consultants who specialize in aiding the indexing process itself. We're otherwise doing very well with SEO, on-page especially, besides, the competition for our "long-tail" keyword phrases is pretty low, so our success hinges mostly on the number of pages indexed. Our main competitor has achieved approx 20MM pages indexed in just over one year's time, along with an Alexa 2000-ish ranking. Noteworthy qualities we have in place: page download speed is pretty good (250-500 ms) no errors (no 404 or 500 errors when getting spidered) we use Google webmaster tools and login daily friendly URLs in place I'm afraid to submit sitemaps. Some SEO community postings suggest a new site with millions of pages and no PR is suspicious. There is a Google video of Matt Cutts speaking of a staged on-boarding of large sites, too, in order to avoid increased scrutiny (at approx 2:30 in the video). Clickable site links deliver all pages, no more than four pages deep and typically no more than 250(-ish) internal links on a page. Anchor text for internal links is logical and adds relevance hierarchically to the data on the detail pages. We had previously set the crawl rate to the highest on webmaster tools (only about a page every two seconds, max). I recently turned it back to "let Google decide" which is what is advised.

  • Do you care about your Oracle System Support experience?

    - by user12244613
    It has been a while since I blogged about Systems Support within Oracle. I want to take this opportunity to raise awareness of how Oracle is communicating out to its systems customers. Previously every item to be communicated was sent independently via an email message however, not all messages appear to be being getting the attention they require. In an effort to ensure Oracle is reaching all of our Sun and Oracle System customers, we have created the Oracle Systems Support Newsletter. This monthly newsletter will have a summary of customer support relevant information for you to use and will cover topics that impact your support experience. For example: 1. Did you know that sending explorer content to email addresses with @sun.com is going away soon? For more information, review the Document 1362484.1 2. Are you an Auto Service Request (ASR) user? If yes, here are the latest changes: · ASR Manager accepts My Oracle Support User Name (email address) and password. [Doc ID 1345484.1] · ASR IP Address for secure file transfer has changed [Doc ID 1338575.1] · ASR No Heartbeat Status - Find out how to resolve [Doc ID 1346328.1] 3. Did you notice we have changed the Service Request options for Hardware and introduced a new problem category called “Automated Diagnosis”? This service streamlines the data you send in and then automatically provides an update of known issues found in your My Oracle Support Service Request. This feature also fast tracks hardware failures by sending parts as soon as the data is analyzed. Have you used this new feature? If yes tell us about it – take the 5minute survey 4. Are you being proactive or are you still ‘fire fighting’ in the reactive mode? If you are being proactive for your Oracle System products you might have used Oracle Sun System Analysis. Did you finding this helpful? Can we improve it? You tell us, take the 5minute survey 5. Are you aware that if you attach files to your Service Request it enables the support engineer to start work straight away? For a summary of products and files review the Newsletter. 6. Are you struggling to find patches or firmware or product downloads? If yes, these types of issues are all addressed in the Newsletter. If this is the type of information you want to know about each month, then take time to read the Newsletter link and bookmark it in My Oracle Support so you can stay informed. Thanks for your time.

  • EPM 11.1.2.2.000 release - considerations

    - by THE
    (guest Article by Nancy) Please be aware with the upcoming release of EPM v11.1.2.2.000, it is highly recommended you first read the"ORACLE® ENTERPRISE PERFORMANCE MANAGEMENT SYSTEM 11.1.2.2.000 Readme" prior to installing this release. We want to highlight the "Installation Information" section which includes the following late-breaking information: Business Rules Migration to Calculation Manager Oracle Hyperion Calculation Manager has replaced Oracle Hyperion Business Rules as the mechanism for designing and managing business rules, therefore, Business Rules is no longer released with EPM System Release 11.1.2.2. If you are applying 11.1.2.2 as a maintenance release, or upgrading to Release 11.1.2.2, and have been using Business Rules in an earlier release, you must migrate to Calculation Manager rules in Release 11.1.2.2. (See Oracle Enterprise Performance Management System Installation and Configuration Guide.) Planning User Interface Enhancements This release of Planning includes a large number of user interface enhancements, as described in Oracle Hyperion Planning New Features. To optimize performance with these new features, you must implement the following recommended configuration. Server: 64-bit, 16 GB physical RAM Client: Optimized for Internet Explorer 9 and Firefox 10 or higher Client-to-Server Connectivity: High-speed internet connection or VPN connection between client and server, client-to-server ping time < 150 milliseconds for best performance The new, improved Planning user interface requires efficient browsers to handle interactivity provided through Web 2.0 like functionality. In our testing, Internet Explorer 7, Internet Explorer 8, and Firefox 3.x are not sufficient to handle such interactivity, and the responsiveness in these versions of browsers is not as fast as the user interface in the previous releases of Planning. For this reason, we strongly recommend that you upgrade your browser to Internet Explorer 9 or Firefox 10 to get responsiveness similar to what you experienced in previous releases. In some instances, the response times in Internet Explorer 7, Internet Explorer 8 and Firefox 3.x could be acceptable. Hence, we suggest that you uptake the new user interface only after you conduct an end user response test and you are satisfied with the results of these tests for these versions of browsers. Please note that it is still possible to leverage the old user interface and features from Planning Release 11.1.2.1. (For more information, see “Using the Planning Release 11.1.2.1 User Interface and Features” in the Oracle Hyperion Planning Administrator's Guide.) IBM HTTP Server and IIS Default Ports Both IBM HTTP Server and IIS Web Server use 80 as their default port. If you are using WebSphere, you must change one of these defaults so that there is no port conflict. If you have further questions, please utilize the  Planning or Essbase MOS Community.

  • Configurable tables in sql database

    - by dot
    I have the following tables in my database: Config Table: ====================================== Start_Range | End Range | Config_id 10 | 15 | 1 ====================================== Available_UserIDs ========================== ID | UserID | Used_YN | 1 | 10 | t | 1 | 11 | f | 1 | 12 | f | 1 | 13 | f | 1 | 14 | f | 1 | 15 | f | ========================== Users ========================== UserId | FName | LName | 10 |John | Doe | ========================== This is used in a reservation system of sorts... which lets an administrator specify a range of numbers that will be assigned to users in the config table. Once the range has been defined, the system then populates the Available_userIDs table with all the numbers in between the range, and sets the Used_YN flag to false As users sign up, they grab the next user_id number that's not in use... and reserve it. Then the system adds a record to the Users table. Once the admin has specified a range, it is possible that they can change it. For example, they can start with 10-15... and then when the range is used up, they should be able to specify another range like 16 - 99. I've put a unique constraint on the Available_UserIDs table, as well as on the Users table - to ensure that UserIds can't be duplicated. My questions are as follows: What's the best way to prevent the admins from using a range that's already in use? I thought of the following options: -- check either the Users table to see if the start range or ending range numbers are being used. If they are, assume that all the numbers in between are in use too, and reject the range. -- let them specify whatever they want, try to populate the Available_UserIDs table. If there are duplicates, just ignore that specific error message from the database and continue on. How do I find gaps in the number ranges? For example, if they specify 10-15, and then 20-25, it'd be nice to be able to somehow suggest on my web page that 16-19 is currently available. I found this article: http://stackoverflow.com/questions/1312101/how-to-find-a-gap-in-running-counter-with-sql But it only seems to return the first available number... so in my example above, it would only return the number 16. I'm sure there's a simpler way to do things that I'm overlooking!

  • Are there any drawbacks to the Major.Minor.YMDD.Build version strategy?

    - by Chu
    I'm trying to come up with a good version strategy to fit our specific needs. We've proposed settling on this and I wanted to ask the question to see if anyone's experience would suggest avoiding this or altering it in any way. Here's our proposal: Versions are released in this format: MAJOR.MINOR.YMDD.BN. Here it is broken out: MAJOR & MINOR are typical; we'll increase MINOR when we feel code and new feature sets warrants it; once every few months most likely. MAJOR will increase ~yearly. YMDD: Y will be the last digit of the current year, so "1" for 2011, "2" for 2012, etc. A non-padded month will be used to keep the number smaller (9 instead of 09 for example). DD of course is the day, padded with a zero for days under 10. BN: BN is the build number and increases by one anytime we make a change to a branch of the code represented by the build, for example: If were to make a build today, our release would be version 5.0.1707.1. I release to QA today and 3 days from now QA finds that a change broke the save functionality on a page. Instead of me changing our current development code, I'd go back to the code that I used to create version 5.0.1707.1, make the fix there, then increase the BN portion of the version and would then re-release 5.0.1707.2 back to QA. In short, anytime a change is made to a branched version that isn't the active dev branch, we'd use the original version number and increase only the BN portion (even if the change happened 3 days, 3 weeks or 3 months from the initial release of that version). Anytime we make a new release from our Active dev branch, we'd come up with a new version based on the M/D of the release using the outlined strategy. We do this once every 2-3 weeks. Are there holes or pitfalls with this? If so, what are they? Thanks EDIT To clarify one point that I didn't get out very well - Oct/Nov/Dec will be two digits, it's only the year that won't be. So 9 for Sept, 10 for Oct, 11 for Nov, etc.

  • New computer hangs on shutdown/reboot, how to troubleshoot?

    - by torbengb
    Summary: My machine hangs on shutdown/restart: all windows and the menu bar disappear but the desktop wallpaper remains, and it stays like that without disk activity forever (hours). It doesn't even show the shutdown screen (the one with the animated dots) where I could hit ESC and watch the shutdown text. How can I troubleshoot this? Details: I've just received a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. The machine boots okay and works OK including WLAN and audio, but the graphics are not OK. Ubuntu offered to install&activate the current recommended Nvidia driver, but the machine hangs on shutdown/restart which prevents the installation of the proper Nvidia driver. I have to cycle the power to reboot. I ran the Update Manager in the hope that the updates would fix the hang-up. At the end of the update-installation it asked to reboot - and got stuck just like before. I see no obvious cause of the freeze and I don't know if it's caused by graphics problems or anything else. The only USB attachment is a mouse/keyboard; I don't have any external storage attached; and I don't have any programs running (the machine freezes even when doing restart right after login). How can I determine what is causing the freeze? How can I fix this? I'm frankly rather disappointed because I bought this new machine in the hopes of getting the graphics to work, which failed miserably on my old machine, even though Ubuntu is supposed to be good with Nvidia. Being a fresh convert from Windows, I was hoping for a happier experience this time, so I'm very much looking forward to your suggestions! ... After posting this question, I see related questions in the right sidebar: this, this, and this. Don't know why these didn't show up while I composed by question. Those questions suggest some ACPI settings but I am not experienced enough to find/change those settings. I'll try the sudo shutdown -h now command when I get home and see if that works, then update this question. I did check the system BIOS but didn't see anything out of the ordinary.

  • 2D Grid Map Connectivity Check (avoiding stack overflow)

    - by SombreErmine
    I am trying to create a routine in C++ that will run before a more expensive A* algorithm that checks to see if two nodes on a 2D grid map are connected or not. What I need to know is a good way to accomplish this sequentially rather than recursively to avoid overflowing the stack. What I've Done Already I've implemented this with ease using a recursive algorithm; however, depending upon different situations it will generate a stack overflow. Upon researching this, I've come to the conclusion that it is overflowing the stack because of too many recursive function calls. I am sure that my recursion does not enter an infinite loop. I generate connected sets at the beginning of the level, and then I use those connected sets to determine connectivity on the fly later. Basically, the generating algorithm starts from left-to-right top-to-bottom. It skips wall nodes and marks them as visited. Whenever it reaches a walkable node, it recursively checks in all four cardinal directions for connected walkable nodes. Every node that gets checked is marked as visited so they aren't handled twice. After checking a node, it is added to either a walls set, a doors set, or one of multiple walkable nodes sets. Once it fills that area, it continues the original ltr ttb loop skipping already-visited nodes. I've also looked into flood-fill algorithms, but I can't make sense of the sequential algorithms and how to adapt them. Can anyone suggest a better way to accomplish this without causing a stack overflow? The only way I can think of is to do the left-to-right top-to-bottom loop generating connected sets on a row basis. Then check the previous row to see if any of the connected sets are connected and then join the sets that are. I haven't decided on the best data structures to use for that though. I also just thought about having the connected sets pre-generated outside the game, but I wouldn't know where to start with creating a tool for that. Any help is appreciated. Thanks!

  • Book review: Peopleware: Productive Projects and Teams

    - by DigiMortal
       Peopleware by Tom DeMarco and Timothy Lister is golden classic book that can be considered as mandatory reading for software project managers, team leads, higher level management and board members of software companies. If you make decisions about people then you cannot miss this book. If you are already good on managing developers then this book can make you even better – you will learn new stuff about successful development teams for sure. Why peopleware? Peopleware gives you very good hints about how to build up working environment for project teams where people can really do their work. Book also covers team building topics that are also important reading. As software developer I found practically all points in this book to be accurate and valid. Many times I have found my self thinking about same things and Peopleware made me more confident about my opinions. Peopleware covers also time management and planning topics that help you do way better job on using developers time effectively by minimizing the amount of interruptions by phone calls, pointless meetings and i-want-to-know-what-are-you-doing-right-now questions by managers who doesn’t write code anyway. I think if you follow suggestions given by Peopleware your developers are very happy. I suggest you to also read another great book – Death March by Edward Yourdon. Death March describes you effectively what happens when good advices given by Peopleware are totally ignored or worse yet – people are treated exactly opposite way. I consider also Death March as golden classics and I strongly recommend you to read this book too.

  • Why is my system freezing when I switch users

    - by ZeroDivide
    Hello I've recently upgraded from 13.04 to 13.10 64bit. I'm running AMD graphics with the proprietary drivers. I have two user accounts. Mine(administrator) and my girlfriend's(standard) My girlfriend clicks "switch user" from my lock screen and logs in fine. I then try to click "switch user" from her lock screen and everything goes black. Then the monitor blinks on and off with just a single cursor. I have no way to access the terminal, the system is unresponsive and I have to hit the power button. Even ctrl + alt + f4 or ctrl + alt + t doesn't get me a terminal. When I press the power button on my system, it does start printing out the shutdown sequence on the monitor. Here is my .xsession-errors Script for ibus started at run_im.

  • Choose Custom New Tab Pages in Chrome

    - by Asian Angel
    For most people the default New Tab Page in Chrome works perfectly well for their purposes. But if you would prefer to choose what opens in a new tab for yourself then you will definitely want to have a look at the “Define your own new tab!” extension for Google Chrome. Before Unless you are using a Speed Dial (or similar) extension each time you click on the “New Tab Button” you get the same old page. It would certainly be a lot more satisfying if you could choose custom webpage(s) to open as new tabs. After Once you have the extension installed the best thing to do is click on the “New Tab Button”. That will open up the “Options Page” where you can enter one or two custom website URLs of your choosing. Once you have your custom URLs entered click on “Save”. As soon as you click on the “New Tab Button” your new custom webpage(s) will open. If you chose two webpages the first choice will open focused on the “right side” instead of the “left”. Clicking on the “Home Button” will also open the webpage(s) that you chose. The webpage(s) that you chose will also open as your starting “Home Pages” each time that you start your browser. Conclusion If you have wanted to choose your own custom “New Tab Page” then this is the extension that you have been waiting for.
