  • Can single ESXi host make use of two separete iSCSI box?

    - by user71061
    Hi! I have problem with using multiply iSCSI targets with single ESXi host (in my case they are two FreeNAS hosts, but I suspect that this problem will occur with any two iSCSI box of that same type/model). If I configure two FreeNAS hosts as iSCSI targets (say iSCSI A and iSCSI B), then I can use both of them with my ESXi host, but only one at a time (i.e only iSCSI A or only iSCSI B, but not both of them simultaneously). If I try to add second iSCSI target to my iSCSI adapter (of course it has unique iqn name), then in a details pane of this adapter (it is iSCSI software adapter), I see that total number of paths has increased accordingly, but not total number of devices (so I can't use it as another storage). What should I do? It is impossible to attach two iSCSI targets to single adapter? I'm using free version of ESXi 4.1. Maybe it is an limitation of free version? Thanks in advance for any sugestion.

  • Leaving Microsoft

    - by Stephen Walther
    After two and a half years working with the ASP.NET team, I’ve decided that this is the right time to leave Microsoft and, with the help of some friends, re-launch my ASP.NET training and consulting company. The company has the modest name Superexpert. While working on my Ph.D. at MIT, I was surrounded by professors and students who were passionate about knowledge. During the Internet boom, I was lucky enough to work side-by-side with some very smart and hard-working people to create several successful startups. However, the people I worked with at Microsoft were among the smartest and hardest working. Microsoft hires a small number of people and gives them huge responsibilities. It continues to amaze me that so few people work on the ASP.NET team when you consider how much the team produces. I had the opportunity to work with a number of inspiring people at Microsoft. I’ll miss working with Scott Hunter, Dave Reed, Boris Moore, Eilon Lipton, Scott Guthrie, James Senior, Jim Wang, Phil Haack, Damian Edwards, Vishal Joshi, Mike Pope, Jon Young, Dmitry Robsman, Simon Calvert, Stefan Schackow, and many others. I’m proud of what we accomplished while I was working at Microsoft. We reached out to the jQuery team and changed direction from Microsoft Ajax to jQuery. We successfully contributed several important new features to the open-source jQuery project including jQuery Templates, jQuery Data-Linking, jQuery Globalization, and (as John Resig announced at the last jQuery conference) jQuery Require. I’m looking forward to returning to training and consulting. We want to focus on providing consulting on the “right way” of building ASP.NET websites, which we call Modern ASP.NET applications. By Modern ASP.NET applications, I mean applications built with ASP.NET MVC, jQuery, HTML5, and Visual Studio ALM. Additionally, we want to help companies that have existing ASP.NET Web Forms applications migrate to ASP.NET MVC. If you are interested in having us provide training for your company or you need help building a custom ASP.NET application then please contact us at [email protected] or visit our website at Superexpert.com.

  • SLES 11 - ocfs2 - Locking does not appear to work

    - by Autobyte
    Hi I have two SLES 11 servers that are SAN attached to a Clarion CX-340. The SAN partition has been formatted with ocfs2 and I have both machines setup in a cluster and the cluster is running (all appears to be normal). I have a small java application as a locking test and when I run the application on both machines at the same time, I should get the lock on one server and the other should refuse the lock since the first already holds a lock on that file but in this case both servers get a lock on the same file. Basically my cluster.conf looks like this: node: ip_port = 7777 ip_address = 192.168.10.121 number = 1 name = osrsles10node1 cluster = osrsles10 node: ip_port = 7777 ip_address = 192.168.10.122 number = 2 name = osrsles10node2 cluster = osrsles10 cluster: node_count = 2 name = osrsles10 Please ask for any other info - I really need these locks to be exclusive to each server. Thanks.

  • xterm not wrapping text properly

    - by mulllhausen
    I'm configuring both my gnome-terminal and xterm columns (i still haven't picked which of these I will be using) and I have a couple of issues I would like to fix: the typing area seems to be smaller (fewer columns) than the display area the typed text is not wrapping to the next line when it reaches the end - it just continues back around on the same line, overwriting the prompt (i have set a custom bash prompt with PS1 in case this is relevant) $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 7.1 (wheezy) Release: 7.1 Codename: wheezy $ echo $TERM xterm $ stty -a [peter@pc ~] $ stty -a speed 38400 baud; rows 52; columns 126; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?; swtch = M-^?; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread -clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc ixany imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke $[peter@mine ~] $ # the column width only goes up to here ------------------------------------------------> the results are identical in both the xterm and in gnome-terminal 3.4.1.1 and as you can see, the output of the stty -a command goes right up to the edge of the screen, while the typing does not go that far. I have found that I can get the desired result by setting the columns to a very large number, eg: $ stty cols 1800 this fixes both problems. Is it the right way to go about solving this problem? Will this "break" any of the output from programs? So far I have tried top and stty -a and these seem OK. more info as requested in the comments i found that if i cat some input into a file then the columns actually strech the full width of the terminal window: [peter@mine applications] $ cat > /tmp/asd aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasssssssssssssssssssssssssssssssssssssssssssssssssssssssssssqqqqqqqqqqqqqqqq qqqq does this imply that it is actually bash that is restricting the number of columns and not the terminal? if so then how to alter the number of columns in bash?

  • Sesame OData Browser updated

    - by Fabrice Marguerie
    Since the first preview of Sesame was published, I've been working on improving it with new features.Today, I've published an update that provides the following: Support for hyperlinks (URLs and email addresses) Improved support for the OData format. More OData producers are supported, including Netflix and vanGuide, for example. Fixed display of images (images used to appear mixed up) Support for image URLs Image zoom (try to hover over pictures in Netflix' Titles or MIX10's Speakers) Support for complex types (test this with Netflix' Titles and the OData Test Service's Suppliers) Partial open types support Partial feed customization support (Products.Name and Products.Description are now displayed for http://services.odata.org/OData/OData.svc for example) Partial HTML support Query number is now unique by connection and not globally Support for query continuation (paging) - See the "Load more" button Partial support for <FunctionImport> (see Movies, Series, Seasons, Discs and Episodes with Netflix) Version number is now displayed More links to examples (coming from http://www.odata.org/producers) provided in the connection dialog You can try all this at the same place as before. Choose Netflix in the connection dialog to see most of the new features in action and to get a richer experience. There is a lot more in the pipe. Enough to keep me busy for a few more weeks :-)

  • Can I use a multi-line function or control flow segment into the PowerShellFar editor console

    - by Justin Dearing
    If I am running farmanager with FarNet and PowerShellFar I can bring up a console of sorts by selecting F11 | .NET PowerShell | Editor Console. This console is based on the far editor. I can paste snippets of powershell scripts into this console and edit them. The only problem is if I want to use a multi-line function or control flow segment in the console. If I paste it in it has no effect. If I attempt to type one in I get an error similar to: ERROR: IncompleteParseException: Missing closing '}' in statement block. At line:1 char:42 + foreach ($number in 1..10 ) { $number * 7 <<<< + CategoryInfo : ParserError: (CloseBraceToken:TokenId) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : MissingEndCurlyBrace Is this simply a limitation of PowerShellFar?

  • GPLv2 - Multiple AI chess engines to bypass GPL

    - by Dogbert
    I have gone through a number of GPL-related questions, the most recent being this one: http://stackoverflow.com/questions/3248823/legal-question-about-the-gpl-license-net-dlls/3249001#3249001 I'm trying to see how this would work, so bear with me. I have a simple GUI interface for a game of Chess. It essentially can send/receive commands to/from an external chess engine (ie: Tong, Fruit, etc). The application/GUI is similar in nature to XBoard ( http://www.gnu.org/software/xboard/ ), but was independently designed. After going through a number of threads on this topic, it seems that the FSF considers dynamically linking against a GPLv2 library as a derivative work, and that by doing so, the GPLv2 extends to my proprietary code, and I must release the source to my entire project. Other legal precedents indicate the opposite, and that dynamic linking doesn't cause the "viral" effect of the GPL to propagate to my proprietary code. Since there is no official consensus that can give a "hard-and-fast" answer to the dynamic linking question, would this be an acceptable alternative: I build my chess GUI so that it sends/receives the chess engine AI logic as text commands from an external interface library that I write The interface library I wrote itself is then released under the GPL The interface library is only used to communicate via a generic text pipe to external command-line chess engines The chess engine itself would be built as a command-line utility rather than as a library of any sort, and just sends strings in the Universal Chess Interface of Chess Engine Communication Protocol ( http://en.wikipedia.org/wiki/Chess_Engine_Communication_Protocol ) format. The one "gotcha" is that the interface library should not be specific to one single GPL'ed chess engine, otherwise the entire GUI would be "entirely dependent" on it. So, I just make my interface library so that it is able to connect to any command-line chess engine that uses a specific format, rather than just one unique engine. I could then include pre-built command-line-app versions of any of the chess engines I'm using. Would that sort of approach allow me to do the following: NOT release the source for my UI Release the source of the interface library I built (if necessary) Use one or more chess engines and bundle them as external command-line utilities that ship with a binary version of my UI Thank you.

  • HTML5 Form Validation

    - by Stephen.Walther
    The latest versions of Google Chrome (16+), Mozilla Firefox (8+), and Internet Explorer (10+) all support HTML5 client-side validation. It is time to take HTML5 validation seriously. The purpose of the blog post is to describe how you can take advantage of HTML5 client-side validation regardless of the type of application that you are building. You learn how to use the HTML5 validation attributes, how to perform custom validation using the JavaScript validation constraint API, and how to simulate HTML5 validation on older browsers by taking advantage of a jQuery plugin. Finally, we discuss the security issues related to using client-side validation. Using Client-Side Validation Attributes The HTML5 specification discusses several attributes which you can use with INPUT elements to perform client-side validation including the required, pattern, min, max, step, and maxlength attributes. For example, you use the required attribute to require a user to enter a value for an INPUT element. The following form demonstrates how you can make the firstName and lastName form fields required: <!DOCTYPE html> <html > <head> <title>Required Demo</title> </head> <body> <form> <label> First Name: <input required title="First Name is Required!" /> </label> <label> Last Name: <input required title="Last Name is Required!" /> </label> <button>Register</button> </form> </body> </html> If you attempt to submit this form without entering a value for firstName or lastName then you get the validation error message: Notice that the value of the title attribute is used to display the validation error message “First Name is Required!”. The title attribute does not work this way with the current version of Firefox. If you want to display a custom validation error message with Firefox then you need to include an x-moz-errormessage attribute like this: <input required title="First Name is Required!" x-moz-errormessage="First Name is Required!" /> The pattern attribute enables you to validate the value of an INPUT element against a regular expression. For example, the following form includes a social security number field which includes a pattern attribute: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Pattern</title> </head> <body> <form> <label> Social Security Number: <input required pattern="^\d{3}-\d{2}-\d{4}$" title="###-##-####" /> </label> <button>Register</button> </form> </body> </html> The regular expression in the form above requires the social security number to match the pattern ###-##-####: Notice that the input field includes both a pattern and a required validation attribute. If you don’t enter a value then the regular expression is never triggered. You need to include the required attribute to force a user to enter a value and cause the value to be validated against the regular expression. Custom Validation You can take advantage of the HTML5 constraint validation API to perform custom validation. You can perform any custom validation that you need. The only requirement is that you write a JavaScript function. For example, when booking a hotel room, you might want to validate that the Arrival Date is in the future instead of the past: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Constraint Validation API</title> </head> <body> <form> <label> Arrival Date: <input id="arrivalDate" type="date" required /> </label> <button>Submit Reservation</button> </form> <script type="text/javascript"> var arrivalDate = document.getElementById("arrivalDate"); arrivalDate.addEventListener("input", function() { var value = new Date(arrivalDate.value); if (value < new Date()) { arrivalDate.setCustomValidity("Arrival date must be after now!"); } else { arrivalDate.setCustomValidity(""); } }); </script> </body> </html> The form above contains an input field named arrivalDate. Entering a value into the arrivalDate field triggers the input event. The JavaScript code adds an event listener for the input event and checks whether the date entered is greater than the current date. If validation fails then the validation error message “Arrival date must be after now!” is assigned to the arrivalDate input field by calling the setCustomValidity() method of the validation constraint API. Otherwise, the validation error message is cleared by calling setCustomValidity() with an empty string. HTML5 Validation and Older Browsers But what about older browsers? For example, what about Apple Safari and versions of Microsoft Internet Explorer older than Internet Explorer 10? What the world really needs is a jQuery plugin which provides backwards compatibility for the HTML5 validation attributes. If a browser supports the HTML5 validation attributes then the plugin would do nothing. Otherwise, the plugin would add support for the attributes. Unfortunately, as far as I know, this plugin does not exist. I have not been able to find any plugin which supports both the required and pattern attributes for older browsers, but does not get in the way of these attributes in the case of newer browsers. There are several jQuery plugins which provide partial support for the HTML5 validation attributes including: · jQuery Validation — http://docs.jquery.com/Plugins/Validation · html5Form — http://www.matiasmancini.com.ar/jquery-plugin-ajax-form-validation-html5.html · h5Validate — http://ericleads.com/h5validate/ The jQuery Validation plugin – the most popular JavaScript validation library – supports the HTML5 required attribute, but it does not support the HTML5 pattern attribute. Likewise, the html5Form plugin does not support the pattern attribute. The h5Validate plugin provides the best support for the HTML5 validation attributes. The following page illustrates how this plugin supports both the required and pattern attributes: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>h5Validate</title> <style type="text/css"> .validationError { border: solid 2px red; } .validationValid { border: solid 2px green; } </style> </head> <body> <form id="customerForm"> <label> First Name: <input id="firstName" required /> </label> <label> Social Security Number: <input id="ssn" required pattern="^\d{3}-\d{2}-\d{4}$" title="Expected pattern is ###-##-####" /> </label> <input type="submit" /> </form> <script type="text/javascript" src="Scripts/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="Scripts/jquery.h5validate.js"></script> <script type="text/javascript"> // Enable h5Validate plugin $("#customerForm").h5Validate({ errorClass: "validationError", validClass: "validationValid" }); // Prevent form submission when errors $("#customerForm").submit(function (evt) { if ($("#customerForm").h5Validate("allValid") === false) { evt.preventDefault(); } }); </script> </body> </html> When an input field fails validation, the validationError CSS class is applied to the field and the field appears with a red border. When an input field passes validation, the validationValid CSS class is applied to the field and the field appears with a green border. From the perspective of HTML5 validation, the h5Validate plugin is the best of the plugins. It adds support for the required and pattern attributes to browsers which do not natively support these attributes such as IE9. However, this plugin does not include everything in my wish list for a perfect HTML5 validation plugin. Here’s my wish list for the perfect back compat HTML5 validation plugin: 1. The plugin would disable itself when used with a browser which natively supports HTML5 validation attributes. The plugin should not be too greedy – it should not handle validation when a browser could do the work itself. 2. The plugin should simulate the same user interface for displaying validation error messages as the user interface displayed by browsers which natively support HTML5 validation. Chrome, Firefox, and Internet Explorer all display validation errors in a popup. The perfect plugin would also display a popup. 3. Finally, the plugin would add support for the setCustomValidity() method and the other methods of the HTML5 validation constraint API. That way, you could implement custom validation in a standards compatible way and you would know that it worked across all browsers both old and new. Security It would be irresponsible of me to end this blog post without mentioning the issue of security. It is important to remember that any client-side validation — including HTML5 validation — can be bypassed. You should use client-side validation with the intention to create a better user experience. Client validation is great for providing a user with immediate feedback when the user is in the process of completing a form. However, client-side validation cannot prevent an evil hacker from submitting unexpected form data to your web server. You should always enforce your validation rules on the server. The only way to ensure that a required field has a value is to verify that the required field has a value on the server. The HTML5 required attribute does not guarantee anything. Summary The goal of this blog post was to describe the support for validation contained in the HTML5 standard. You learned how to use both the required and the pattern attributes in an HTML5 form. We also discussed how you can implement custom validation by taking advantage of the setCustomValidity() method. Finally, I discussed the available jQuery plugins for adding support for the HTM5 validation attributes to older browsers. Unfortunately, I am unaware of any jQuery plugin which provides a perfect solution to the problem of backwards compatibility.

  • July, the 31 Days of SQL Server DMO’s – Day 18 (sys.dm_io_virtual_file_stats)

    - by Tamarick Hill
    The sys.dm_io_virtual_file_stats Dynamic Management Function is used to return IO statistic information about each of your database files on your server. As input parameters, this function takes a database_id and a file_id. If you want to return IO statistic information for all files, you can simply pass in NULL values for both of these. Let’s have a look at this function  and examine its results: SELECT db_name(database_id) DatabaseName, * FROM sys.dm_io_virtual_file_stats(NULL, NULL) The first column in the result set is the DatabaseName which is just a column I created using the db_name() system function and the database_id column from this function. Next we have a file_id which represent the ID for the file, whether it be a data file or transaction log file. The ‘sample_ms’ column represents the total time in milliseconds that the instance has been up and running. Next we have the ‘num_of_reads’, ‘num_of_bytes_read’, and later ‘num_of_writes’, and ‘num_of_bytes_written’. These columns represent the number of reads or writes and number of bytes read or written against a particular file. These columns are beneficial when determining how often a particular file is being accessed. The ‘io_stall_read_ms’ and io_stall_write_ms’ columns each represent the the total time in milliseconds that users have had to wait for reads or writes against a file respectively. The ‘io_stall’ column is the sum of both read and write io stalls. The ‘size_on_disk_bytes’ column represents the size of the respective file on your disk subsystem. Lastly the ‘file_handle’ column is simply the Windows File handle. This Dynamic Management Function is useful when you are needing to analyze your database files for the purposes of segregating high IO databases. This DMF gives you a good view of which of your database files are being accessed the most and which ones may be generating the largest IO stalls. These could be your best candidates for moving into separate IO channels. For more information about this DMF, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms190326.aspx Follow me on Twitter @PrimeTimeDBA

  • What am I doing wrong with this cat 6 patch panel wiring?

    - by Max Hodges
    top number is transmitter bottom number is remote terminator 12345678 36145278 is this because I could be mixing T568A and T568B wiring? how do I know if my patch cord is A or B? Do I just look at the plug and match it up with the diagram on the back of the panel somehow? EDIT I read that 36145278 indicates a cross over cable, but I'm not trying to make a cross over. Where did I go wrong? I'm guessing the cable plug is T568A but I wired it to the panel using T568B. So I need to redo it as T568A. But in the future how do I know if I cable is A or B? Cheers!

  • What is the definition of "Big Data"?

    - by Ben
    Is there one? All the definitions I can find describe the size, complexity / variety or velocity of the data. Wikipedia's definition is the only one I've found with an actual number Big data sizes are a constantly moving target, as of 2012 ranging from a few dozen terabytes to many petabytes of data in a single data set. However, this seemingly contradicts the MIKE2.0 definition, referenced in the next paragraph, which indicates that "big" data can be small and that 100,000 sensors on an aircraft creating only 3GB of data could be considered big. IBM despite saying that: Big data is more simply than a matter of size. have emphasised size in their definition. O'Reilly has stressed "volume, velocity and variety" as well. Though explained well, and in more depth, the definition seems to be a re-hash of the others - or vice-versa of course. I think that a Computer Weekly article title sums up a number of articles fairly well "What is big data and how can it be used to gain competitive advantage". But ZDNet wins with the following from 2012: “Big Data” is a catch phrase that has been bubbling up from the high performance computing niche of the IT market... If one sits through the presentations from ten suppliers of technology, fifteen or so different definitions are likely to come forward. Each definition, of course, tends to support the need for that supplier’s products and services. Imagine that. Basically "big data" is "big" in some way shape or form. What is "big"? Is it quantifiable at the current time? If "big" is unquantifiable is there a definition that does not rely solely on generalities?

  • BizTalk 2009 - BizTalk Server Best Practice Analyser

    - by StuartBrierley
    The BizTalk Server Best Practices Analyser  allows you to carry out a configuration level verification of your BizTalk installation, evaluating the deployed configuration but not modifying or tuning anything that it finds. The Best Practices Analyser uses "reading and reporting" to gather data from different sources, such as: Windows Management Instrumentation (WMI) classes SQL Server databases Registry entries When I first ran the analyser I got a number of errors, if you get any errors these should all be acted upon to resolve them, you should then run the scan again and see if any thing else is reported that needs acting upon. As you can see in the image above, the initial issue that jumped out to me was that the SQL Server Agent was not started. The reasons for this was absent mindedness - this run was against my development PC and I don't have SQL/BizTalk actively running unless I am using them.  Starting the agent service and running the scan again gave me the following results: This resolved most of the issues for me, but next major issue to look at was that there was no tracking host running.  You can also see that I was still getting an error with two of the SQL jobs.  The problem here was that I had not yet configured these two SQL jobs.  Configuring the backup and purge jobs and then starting the tracking host before running the scan again gave: This had cleared all the critical issues, but I did stil have a number of warnings.  For example on this report I was warned that the BizTalk Message box is hosted on the BizTalk Server.  While this is known to be less than ideal, it is as I expected on my development environment where I have installed Visual Studio, SQL and BizTalk on my laptop and I was happy to ignore this and other similar warnings. In your case you should take a look at any warnings you receive and decide what you want to do about each of them in turn.

  • Linux / apache web-server segmentation fault warnings

    - by jeroen
    Lately I have been receiving a lot of segmentation fault warnings on my web-server. The warnings look like: [notice] child pid xxxx exit signal Segmentation fault (11) I have consulted with the server provider (it is a dedicated redhat enterprise server) and they could not find anything. What I have done so far: Since the error I have already tried the following: I have added more ram I have turned off / turned on several php modules (they sent me to a web-page someone had the same problem, caused by an excessive amount of php modules) At the moments the warnings occur, there seems to be plenty of free ram left and the number of processes is very low (the number of httpd processes is about a quarter of the maximum allowed). What can be causing these errors? Edit: current versions apache: 2.0.52 php: 5.2.8 RHEL 4 Edit 2: Although I asked this a long time ago, I never was able to solve it until I upgraded to php 5.3.

  • Thinktecture.IdentityModel: Comparing Strings without leaking Timinig Information

    - by Your DisplayName here!
    Paul Hill commented on a recent post where I was comparing HMACSHA256 signatures. In a nutshell his complaint was that I am leaking timing information while doing so – or in other words, my code returned faster with wrong (or partially wrong) signatures than with the correct signature. This can be potentially used for timing attacks like this one. I think he got a point here, especially in the era of cloud computing where you can potentially run attack code on the same physical machine as your target to do high resolution timing analysis (see here for an example). It turns out that it is not that easy to write a time-constant string comparer due to all sort of (unexpected) clever optimization mechanisms in the CLR. With the help and feedback of Paul and Shawn I came up with this: Structure the code in a way that the CLR will not try to optimize it In addition turn off optimization (just in case a future version will come up with new optimization methods) Add a random sleep when the comparison fails (using Shawn’s and Stephen’s nice Random wrapper for RNGCryptoServiceProvider). You can find the full code in the Thinktecture.IdentityModel download. [MethodImpl(MethodImplOptions.NoOptimization)] public static bool IsEqual(string s1, string s2) {     if (s1 == null && s2 == null)     {         return true;     }       if (s1 == null || s2 == null)     {         return false;     }       if (s1.Length != s2.Length)     {         return false;     }       var s1chars = s1.ToCharArray();     var s2chars = s2.ToCharArray();       int hits = 0;     for (int i = 0; i < s1.Length; i++)     {         if (s1chars[i].Equals(s2chars[i]))         {             hits += 2;         }         else         {             hits += 1;         }     }       bool same = (hits == s1.Length * 2);       if (!same)     {         var rnd = new CryptoRandom();         Thread.Sleep(rnd.Next(0, 10));     }       return same; }

  • Experience the iPad UI On Your PC

    - by Matthew Guay
    Want to test drive iPad without heading over to an Apple store?  Here’s a way you can experience some of the iPad UI straight from your browser! The iPad is the latest gadget from Apple to wow the tech world, and people even waited in line all night to be one of the first to get their hands on one.  Thanks to a simple JavaScript trick, however, you can get a feel for some of its new features without leaving your computer.  This won’t let you try out everything on the iPad, but it will let you see how the new lists and pop-over menus work just like they do in the new apps. Test drive the iPad’s UI from your browser Normally, the Apple iPhone developer library online looks like a standard webpage. But, on the iPad, it looks and feels like a full-blown native iPad app.  With a nifty JavaScript trick from boredzo.org you can use this same interface on your PC.  Since the iPad uses the Safari browser, we ran this test in Safari for Windows.  If you don’t already have it installed, you can download it from Apple (link below) and setup as normal. Now, open Safari and browse to Apple’s developer page at: http://www.developer.apple.com   Now, enter the following in the address bar, and press Enter. javascript:localStorage.setItem('debugSawtooth', 'true')   Finally, click this link to go to the iPhone OS documentation. http://developer.apple.com/iphone/library/iPad/ After a short delay, it should open in full iPad style! The left menu works just like the menus on the iPad, complete with transitions.  It feels entirely like a native application, instead of a webpage.  To scroll through text, click and pull up or down similar to the way you would use it on a touch screen. Some pages even include a pop-over menu like many of the new iPad apps use. Note that the page will be rendered for the size of your browser, and if you resize your window the page will not resize with it.  Simply press F5 to reload the page, and it will resize to fit the new window size.  If you resize your window to be tall and narrow, like the iPad in horizontal mode, the webpage will change and the left menu will disappear in lieu of a drop-down menu just like it would if you rotated the iPad. This works in Chrome as well, since it, like Safari, is based on Webkit.  However, it didn’t seem to work in our test on Firefox or other browsers. We’ve previously covered how you can experience some of the iPhone’s UI with the online iPhone user guide.  Check it out if you haven’t yet: View Mobile Websites in Windows with Safari 4 Developer Tools Conclusion Although this doesn’t let you really try out all of the iPad’s interface, it at least gives you a taste of how it works.  It’s exciting to see how much functionality can be packed into webapps today.  And don’t forget, How-to Geek is giving away an iPad to a random fan!  Head over to our Facebook page and fan How-to Geek if you haven’t already done so.

  • Windows 2008 R2 CA and auto-enrollment: how to get rid of >100,000 issued certificates?

    - by HopelessN00b
    The basic problem I'm having is that I have 100,000 useless machine certificates cluttering up my CA, and I'd like to delete them, without deleting all certs, or time jumping the server ahead, and invalidating some of the useful certs on there. This came about as a result of accepting a couple defaults with our Enterprise Root CA (2008 R2) and using a GPO to auto-enroll client machines for certificates to allow 802.1x authentication to our corporate wireless network. Turns out that the default Computer (Machine) Certificate Template will happily allow machines to re-enroll instead of directing them to use the certificate they already have. This is creating a number of problems for the guy (me) who was hoping to use the Certificate Authority as more than a log of every time a workstation's been rebooted. (The scroll bar on the side is lying, if you drag it to the bottom, the screen pauses and loads the next few dozen certs.) Does anyone know how to DELETE 100,000 or so time-valid, existing certificates from a Windows Server 2008R2 CA? When I go to delete a certificate now, now, I get an error that it cannot be delete because it's still valid. So, ideally, some way to temporarily bypass that error, as Mark Henderson's provided a way to delete the certificates with a script once that hurdle is cleared. (Revoking them is not an option, as that just moves them to Revoked Certificates, which we need to be able to view, and they can't be deleted from the revoked "folder" either.) Update: I tried the site @MarkHenderson linked, which is promising, and offers much better certificate manageability, buts still doesn't quite get there. The rub in my case seems to be that the certificates are still "time-valid," (not yet expired) so the CA doesn't want to let them be deleted from existence, and this applies to revoked certs as well, so revoking them all and then deleting them won't work either. I've also found this technet blog with my Google-Fu, but unfortunately, they seemed to only have to delete a very large number of certificate requests, not actual certificates. Finally, for now, time jumping the CA forward so the certificates I want to get rid of expire, and therefore can be deleted with the tools at the site Mark linked is not a great option, as would expire a number of valid certificates we use that have to be manually issued. So it's a better option than rebuilding the CA, but not a great one.

  • Zabbix - Some of the monitored items don't refreh

    - by Niro
    I'm experiencing a strange issue with Zabbix monitoring a MySQL server. Most of the data from the server such as MySQL queries per second and MySQL uptime , Buffers memory etc. update nicely while some data like CPU iowait time (avg1) , Host local time ,MySQL number of threads and other items which were monitored in the past has last check time of about a week ago. I can't find any logic in this, for example Mysql number of threads and Mysql queries per second are obtained in a similar way so it does not make sense one of them is monitored and one is not. Please help- how can I fix this? Update - I used zabbix_get from the zabbix server to check one of the items on the zabbix client and it works so the problem must be on the zabbix server side

  • BIEE Drilling Down and then Across

    - by Tim Dexter
    Slightly off topic today but if you are working with OBIEE in conjunction with BIP its not that far off. Some of you may know, I now get to play with the whole BI suite, I have been for nearly 2 years. Today, I was working with BIEE and wanted to share what I thought was a neat trick. I have to thank Rob Lindsley on our team for the pointers to get it working. The problem I had was that I had set up a drill down hierarchy that took the user down a couple of levels to the bottom project number level. I needed for the user to then be able to click the project number to navigate across to another more detailed report on that project. By default, there is no link, you are at the bottom of a hierarchical drill! There is nothing you can do in the data model (that Im aware of) but you can use a neat trick to get BIEE to allow you to navigate from the bottom rung of the hierarchy. Add the bottom level column to an Answer report. Go into the column properties and set the navigation target. The trick is to then set the current column properties as the system-wide default for that column. You can then actually delete the column from your report. Now as you drill down the hierarchy and reach what was the bottom you will still have a link for the user to punch over to the detail report, sweeeet! The other benefit is that whenever you add the column to a report the link will be available to the detail report, unless you want to override it of course.

  • Use Your Chart-Drawing Skills to Win a Free Chrome Cr-48 Notebook

    - by ETC
    Today Google announced that they are partnering with a number of Chrome web application developers to distribute a number of their Chrome OS Notebooks to lucky fans. That’s when we noticed something interesting that can greatly increase your odds of getting one. Unlike Box, MOG, and Zoho, who are doing random giveaways, the LucidChart giveaway is based on a contest of skill – they are picking the best drawings using their flowchart tool and giving away Chrome Notebooks to the winners. So all you have to do is create one of the most interesting drawings / charts, and you will get your hands on one. We’ve also confirmed this with the fine people at LucidChart, who told us “any user who spends a bit of time and effort to do something creative has a good shot at winning one.” How great is the Chrome Cr-48 Notebook? What’s it all about? We wouldn’t know, since Google hasn’t given us here at How-To Geek an opportunity to use one, despite our attempts. It’s sad, since we’re huge fans of the Chrome browser, that we can’t share our Chrome notebook experiences with hundreds of thousands of daily subscribers and millions of monthly visitors. Hint.

  • Announcing Berkeley DB Java Edition Major Release

    - by Eric Jensen
    Berkeley DB Java Edition 5.0 was just released. There are a number of new features, enhancements, and options in there that our users have been asking for. Chief among them is a new class called DiskOrderedCursor, which greatly increases performance of systems using spinning platter magnetic hard drives. A number of users expressed interest in this feature, including Alex Feinberg of LinkedIn. Berkeley DB Java Edition is part of Project Voldemort, a distributed key/value database used by LinkedIn. There have been many other improvements and optimizations. Concurrency is significantly improved, as is the performance of update and delete operations. New and interesting methods include Environment.preload, which allows multiple databases to be preloaded simultaneously. New Cursor methods enable for more effective searching through the database. We continue to enhance Berkeley DB Java Edition’s High Availability as well. One new feature is the ability to open a replicated node read-only when the master is unavailable. This can allow critical systems to continue offering some functionality, even during a network or master node failure. There’s a lot more in release 5.0. I encourage you to take a look at the extensive changelog yourself. As always, you can download the new release and try it out here: http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html
