    - by AlecWhittington
    It has been a few weeks since S#arp Architecture 1.5 RTM has been released. While it was a major success a few issues were found that needed to be addressed.

  • How do I make a backup of a live server?

    - by Jurily
    At my new job, I have a production server with the following qualities: Windows (XP I think), ancient hardware Absolutely vital database No backups whatsoever Everyone in the company has full admin rights, the passwords are stored in a .txt on the global share No installers, except for the OS The machine itself is sitting on a wooden shelf 5 feet above the ground against an external wall with frequent truck traffic on the other side; the shelf is already bent from the constant load Hasn't been rebooted in $DEITY knows how long, my predecessor wasn't even sure if it would survive it UPS is installed, but since everything is hooked up to it, it would last 10 minutes tops No spare parts or hardware budget How do I make a full backup with minimal impact on the server? I'm not sure how close it is to a total meltdown. For all I know, plugging in a USB stick could kill the company, and of course it will be all my fault, since "it was running fine before you touched it". The ideal solution would be a VM, so I have a test environment as well (separate of course).

  • Using WebSphere CloudBurst with PowerVM to AIX virtualization over a cloud

    - by ADD Geek
    hi there we are studying the virtualization option to reduce our datacenter cost, and this research was assigned to me. we looked into alternatives and we almost reached a conclusion that PowerVM is the only option to virtualize pSeries servers. we found no signs of cloud support explicitly mentioned in any document, however there was the mention of CloudBurst. from the videos we watched and the documents we read, it seems that CloudBurst is more oriented towards Application Servers (WebSphere Software). but our environment is not relying only on WebSphere. we have some banking applications, Oracle Databases and MQ/Broaker. the question is: 1- can we virtualize the existing applications (all running AIX) on a cloud running on top of some of the existing servers? (given that we do the sizing properly) 2- is PowerVM to run on top of CloudBurst? 3- if the above solution is applicable, is this some sort of HA solution (since the VM will run on top of multiple physical boxes, while the same physical box will run multiple live images) thanks for your help

  • Encrypt remote linux server

    - by Margaret Thorpe
    One of my customers has requested that their web server is encrypted to prevent offline attacks to highly sensitive data contained in a mysql database and also /var/log. I have full root access to the dedicated server at a popular host. I am considering 3 options - FDE - This would be ideal, but with only remote access (no console) I imagine this would be very complex. Xen - installing XEN and moving their server within a XEN virtual machine and encrypting the VM - which seems easier to do remotely. Parition - encrypt the non-static partitions where the sensitive data resides e.g. /var /home etc. What would be the simplist approach that satisfies the requirements?

  • print job doesn't go to print queue

    - by flatsguide
    I have two printers hooked up to my intel imac. I am having a printing error. It seems that whenever i try to print (a simple text doc) I am unable to get the print job to go to print queue with one of my printers. I have a HP c7280 and a HP c3100. I am able to get one working properly, but the other doesn't seem to allow it to go to the print queue. I have switched usb cables (with the printer that I know works) and both printers are recognized by the computer in the printer preferences pane. I've tried reseting the printer system in the printer setup utility.. reloaded the drivers from HP.. etc. If anyone has a suggestion or could point me to a little help i'd be VERY grateful Best Regards..

  • How can I tell how many bits my ssh key is?

    - by yairchu
    I already created an ssh key for myself sometime in the past. I don't remember "how many bits" it is. How can I tell? I'm wondering because I'm using hosting at nearlyfreespeech.net and their faq says: Can I configure my ssh connection to use a public key? ... we will not install keys that have a length less than 1536 bits ... We prefer that you use a key at least 2048 bits in length, and if you are generating a new key, the recommended length is 4096 bits.

  • Error: Only LDAP Connection Strings are Supported against Active Directory

    I have the following ASP.NET Membership section defined in the Web.config file: <membership defaultProvider="AspNetActiveDirectoryMembershipProvider"> <providers> <clear/> <add connectionStringName="ADService" connectionUsername="umanage" connectionPassword="letmein" enablePasswordReset="true" enableSearchMethods="true" applicationName="uManage" clientSearchTimeout="30" serverSearchTimeout="30" name="AspNetActiveDirectoryMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> The Connection string looks like this: <add name="ADService" connectionString="ldap://familynet.local" /> Whenever I call the following code: Membership.GetAllUsers(); I get the following error: Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Only LDAP connection strings are supported against Active Directory and ADAM.

  • Client or server side invocation to google API?

    - by Raffo
    I'm writing a web application with GWT and I've to call google calendar's API to retrieve some information. I now have this dilemma: Is it better to use a client side invocation (using javascript or gwt-gdata library) or using the standard google library for java to call the service at server side and then passing all the data to the client via an async call?? I'm not able to understand pros and cons of the two approaches... In particular, I need to call several time the calendar API to retrieve events and let users add new ones, etc. Can you help me?

  • Is there a way to parse XML via SAX/DOM with line numbers available per node.

    - by Chris
    I already have written a DOM parser for a large XML document format that contains a number of items that can be used to automatically generate Java code. This is limited to small expressions that are then merged into a dynamically generated Java source file. So far - so good. Everything works. BUT - I wish to be able to embed the line number of the XML node where the Java code was included from (so that if the configuration contains uncompilable code, each method will have a pointer to the source XML document and the line number for ease of debugging). I don't require the line number at parse-time and I don't need to validate the XML Source Document and throw an error at a particular line number. I need to be able to access the line number for each node and attribute in my DOM or per SAX event. Any suggestions on how I might be able to achieve this? P.S. Also, I read the StAX has a method to obtain line number whilst parsing, but ideally I would like to achieve the same result with regular SAX/DOM processing in Java 4/5 rather than become a Java 6+ application or take on extra .jar files.

  • WCF, 4.0, Bidirectional...

    - by TomTom
    ...what options are there now with .NET 4.0, in a way that does support NAT for the client side (i.e. client behind NAT). I would prefer to use something HTTP based, but that is a weak condition - I think mid term I will have some non http communication outside WCF anyway, so proxy traversal is something I could delay. Pre .NET 4.0 there was the issue that basically the server-client channel would be opened from the server, which made NAT something non-traversable. Polling is not acceptable - we talk time sensitive information here. So, what are my options now?

  • Scaled ellipse over button, button not clickable

    - by user336720
    Hi, I'm scaling an ellipse in an animation with the following code: ScaleTransform myScTransform = new ScaleTransform(); TransformGroup myTransGroup = new TransformGroup(); myTransGroup.Children.Add(myScTransform); newPHRadio.RenderTransform = myTransGroup; newPHRadio.RenderTransformOrigin = new Point(0.5, 0.5); Storyboard story = new Storyboard(); DoubleAnimation xAnimation = new DoubleAnimation(1, ph.Bereik, new Duration(TimeSpan.FromSeconds(2))); DoubleAnimation yAnimation = new DoubleAnimation(1, ph.Bereik, new Duration(TimeSpan.FromSeconds(2))); DoubleAnimation doorzichtig = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(2))); Storyboard.SetTarget(xAnimation, newPHRadio); Storyboard.SetTarget(yAnimation, newPHRadio); Storyboard.SetTarget(doorzichtig, newPHRadio); DependencyProperty[] propertyChainX = new DependencyProperty[] { Ellipse.RenderTransformProperty, TransformGroup.ChildrenProperty, ScaleTransform.ScaleXProperty }; DependencyProperty[] propertyChainY = new DependencyProperty[] { Ellipse.RenderTransformProperty, TransformGroup.ChildrenProperty, ScaleTransform.ScaleYProperty }; string thePath = "(0).(1)[0].(2)"; Storyboard.SetTargetProperty(xAnimation, new PropertyPath(thePath, propertyChainX)); Storyboard.SetTargetProperty(yAnimation, new PropertyPath(thePath, propertyChainY)); Storyboard.SetTargetProperty(doorzichtig, new PropertyPath(Ellipse.OpacityProperty)); story.Children.Add(xAnimation); story.Children.Add(yAnimation); story.Children.Add(doorzichtig); story.Duration = new Duration(TimeSpan.FromSeconds(60 / ph.Frequentie)); story.RepeatBehavior = RepeatBehavior.Forever; story.Begin(); The ellipse is constructed with the following code: Ellipse newPHRadio = new Ellipse(); newPHRadio.Width = 1; newPHRadio.Height = 1; newPHRadio.SetValue(Canvas.LeftProperty, ph.xPositie + 7); newPHRadio.SetValue(Canvas.TopProperty, ph.yPositie + 7); newPHRadio.SetValue(Canvas.ZIndexProperty, 3); newPHRadio.Stroke = new SolidColorBrush(Colors.Black); newPHRadio.StrokeThickness = 0.03; Now the ellipse is scaled over an button which has a z-index of 1. With a static ellipse and no fill, the button is clickable. Now there is no fill as well but the button is not clickable. Can someone tell me how to fix this?

  • Image change on mouseover with jQuery..

    - by playahabana
    Hi, I am a comlete beginner to pretty much all things web design and am trying to construct my first website. I am attempting to hand code it without the ue of a CMS in order to learn as much as possible as quickly as possible. I am trying to make an imge change on mouseover for my top nav menu, and have the following jQuery functions: $(document).ready(function(){ $(".navlist img").each(function) { rollsrc = $(this).attr("src"); rollON = rollsrc.replace(/.jpg$/ig,"_link.png"); $("<img>").attr("src",rollON); $(".navlist a").mouseover(function(){ }); imgsrc= $(this).children("img").attr("src"); matches = imgsrc.match(/_link.png); if (!matches) { imgsrcON = imgsrc.replace(/.jpg$/ig,"_link.png"); $(this).children("img").attr("src", imagesrcON); } $(".navlist a").mouseout(function(){ $(this).children("img").attr("src", imgsrc); }); }); my html is as follows: <div id="nav"> <ul class="navmenu"> <li><a href="index.html"><img class="swap" src="images/links/home.jpg" alt="Home" border="none"></a></li> <li><a href="#"><img class="swap" src="images/links/ourbar.jpg" alt="Our Bar" border="none"></a> <ul class="navdrop"> <li ><a href="#"><img class="swap" src="images/links/cockteles.jpg" alt="Our Cocktails" border="none"></a></li> <li ><a href="#"><img class="swap" src="images/links/celebrate.jpg" alt="Celebrate in Style" border="none"></a></li> </ul> </li> <li><a href="#"><img class="swap" src="images/links/ourcigars.jpg" alt="Our Cigars" border="none"></a> <ul class="navdrop"> <li><a href="#"><img class="swap" src="images/links/edicionlimitadas.jpg" alt="Edition Limitadas" border="none"></a></li> <li><a href="our_cigars.html"><img class="swap" src="images/links/cigartasting.jpg" alt="Cigar Tastings" border="none"></a></li> </ul> </li> <li><a href="#"><img class="swap" src="images/links/personalcigar.jpg" alt="Personal Cigar Roller" border="none"></a></li> <li><a href="our_cigars.html"><img class="swap" src="images/links/photogallery.jpg" alt="Photo Gallery" border="none"></a></li> <li><a href="#"><img class="swap" src="images/links/contactus.jpg" alt="Contact Us" border="none"></a></li> </ul></div></div><!--end banner--> the image src for the alt image is in the form eg."images/links/home_link.png" and is the same for every image. I have checked this and checked this, could some body please give me a pointer as to where I am going wrong? Or a pointer to a tutorial for this effect? I have looked at a few and this seems to be the best for what I am attempting, but as I said I don't really know what I'm doing so any advice gratefully received.....

  • Why LLBLGen Pro v3.0 is better than the regular designer for EF v4.0

    As a comment to my blogpost about the 12 minute long video of LLBLGen Pro with Entity Framework v4.0, Burton Roberts asks: Could you list the advantages of using llblgen pro 3 with Entity Framework versus using EF alone? Of course! Now, I know these posts are often classified as 'marketing' but so be it. Why is the LLBLGen Pro v3.0 designer better for Entity Framework v4.0 than the regular Entity Framework designer? Below I'll give an (incomplete) list of features you have at your disposal...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • What is the purpose of Process class in Java?

    - by Nitesh Panchal
    Runtime objRuntime = Runtime.getRuntime(); String strBackupString = "mysqldump -u " + userName + " -p" + password + " " + dbName; Process objProcess = objRuntime.exec(strBackupString); This is used for backup of database. But what exactly happens? Can anybody make me explain, what is the purpose of Runtime and Process class? Is this class used to act as if we are typing command from command prompt? Then what should i pass to objRuntime.exec() if i want to open notepad? And is the command executed as soon as we call exec method? If yes, then what purpose does Process serve here? I really can't understand these two classes. Please make me understand. Thanks in advance :)

  • How to enable i18n from within setup_app in websetup.py ?

    - by daniel
    From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  • Can php query the results from a previous query?

I sort of want to do: $rs1 = do_query( "SELECT * FROM animals WHERE type = 'fish'" ); $rs2 = do_query( "SELECT * FROM rs1 WHERE name = 'trout'" );
