• Is it possible to install Windows 8 on the SanDisk ReadyCache 32GB SSD drive?

  - by halil ibrahim

  I bought the SanDisk ReadyCache 32GB SSD drive this week. I didn't know about the caching stuff and thought that I would be able to install Windows 8 on it. Now I'm using it as a cache drive with the ExpressCache software. But I wonder if it is possible to use this SSD as a primary system drive with an operating system installed on it. I've tried to format the disk via Windows Disc Manager Tool, but the format option is disabled. Only delete and information options are allowed. Can you help me with this?

• How to get around the event bubble using jQuery's: .live()

  - by Nick

  Hi there. Here is the code in question: $(".navItems>ul>li").live('click', function(){ var selectorID = $(this).attr('id'); $(".infoList").slideUp('fast', function(){ switchTabInfo(selectorID); }); function switchTabInfo(selectorID){ var actionID = selectorID.substring(4); actionID = "#" + actionID; $(actionID).slideDown(); } So in short i have a these .infoList classes with id names tied to back to the nav li id. That lists item's id might be nav_testsHistory for example. With all the content boxes hidden by class name this javascript makes a pleasing slide up, down effect. But the third content box flickers as will the second one after a third box push. It slides up and down a second unnecessary time. If I add an alert like this: $(".navItems>ul>li").live('click', function(){ var selectorID = $(this).attr('id'); $(".infoList").slideUp('fast', function(){ switchTabInfo(selectorID); alert('bubble'); }); The alert fires 3 times?! So my research took to reading about the event bubble. What I cannot find is how to check if it has been fired. I have not tried setting an input val and doing a tf test around the nested slider action. Cause that's crude. More info, all the code above is in a function, which is in an init() function, which is called on document ready. That's the only js file besides jquery 1.3.2. What do you guys think?

• how to pass values from one page to another on jquery form submit

  - by andy787899

  I'm trying to build a form using php & jquery, but I'm a little confused as to what to do with the jquery portion of it... Basically, when the user submits the first form, I want to direct them to the "next step" form, but I want to retain the values submitted from the first one in a hidden input field... If someone can either show me how or point me to a good tutorial, I'd appreciate it... I don't have any of the php or jquery yet, and this is just a simplified version of the html markup... //first.php <form name="form1" method="post" action="second.php"> <input type="text" name="name" value="" />Name <input type="submit" name="step1" value="Next" /> </form> //second.php <form name="form2" method="post" action="process.php"> <input type="hidden" name="name" value="{$_POST['name']}" /> <input type="text" name="message" value="" />message <input type="submit" name="step2" value="Finish" /> </form>

• Custom listbox sorting

  - by Arcadian

  I need to sort the data contained within a number of listboxes. The user will be able to select between two different types of sorting using radio boxes, one of which is checked by default on form load. I have created the IF statements needed in order to test whether the checked condition is true for that radio button. but i need some help to create the custom sort algorithms. Each list with contain similar looking data, the only difference in the prefix with which each line starts. For example each line in the first listbox starts with the prefix "G30" and the second listbox will be "G31" and so on. There are 10 listboxes in total (G30-G39 in terms of prefixes). The first search algorithm has to sort the lines by the number order of the first 13 chars. Example: This is how the data looks before sorting G35:45:58:11 JG07 G35:45:20:41 JG01 G35:58:20:21 JG03 G35:66:22:20 JG05 G35:45:85:21 JG02 G35:64:56:11 JG03 G35:76:35:11 JG02 G35:77:97:12 JG03 G35:54:29:11 JG01 G35:55:51:20 JG01 G35:76:24:20 JG06 G35:76:55:11 JG01 and this is how it should look after sorting G35:45:20:41 JG01 G35:45:58:11 JG07 G35:45:85:21 JG02 G35:54:29:11 JG01 G35:55:51:20 JG01 G35:58:20:21 JG03 G35:64:56:11 JG03 G35:66:22:20 JG05 G35:76:24:20 JG06 G35:76:35:11 JG02 G35:76:55:11 JG01 G35:77:97:12 JG03 as you can see, the prefixes are the same. so it is sorted, lowest first, by the next pair integers, then the next pair and the next but not by the value after "JG". the second sort algorithm will ignore the first 13 chars and sort by order of the value after "JG", highest first. any help? theres some rep in it for you :) thanks in advance

• Is it possible to manipulate a request before IIS assigns that request to a specific site?

  - by Deane

  Is it possible to manipulate an inbound request at the IIS level, before it even gets assigned to site on the server? Essentially, I want to rewrite this -- www.somegenericdomain.com?site=someotherdomain To this -- www.someotherdomain.com And I need to do this before IIS picks which site the request belongs to, so I need to change the host header prior to this point. Possible, or crazy? We're running IIS7.

• Why am I unable to turn off recursion in ISC BIND?

  - by nbolton

  Here's my named.conf.options file: options { directory "/var/cache/bind"; dnssec-enable yes; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; # disable recursion recursion no; }; I've tried adding allow-recursion { "none"; } before recursion but this also has no effect; I'm testing it by using nslookup on Windows, and using google.com. as the query (and it returns an IP, so I assume recursion is on). This issue occurs on two servers with similar setups.

• Signal processing or algorithmic programming for a PLC

  - by james singen smythe

  I have an application that takes voltages and temperatures as analog inputs and does some processing using an algorithm which involves signal processing such as low-pass filtering, exponential smoothing, and other steps which might typically be done in a high-level programming language such as C or C++. I'm curious how I could perform these same steps using a PLC, and in particular, the Allen-Bradley Control-Logix system? It seems to me that the instruction set with ladder logic is too limited for this. Could I perform this using structured text?

  - by battousai622

  Im reading in 2 csv file: store_inventory & new_acquisitions... I want to be able to compare the store_inventory csv file with new_acquisitions. 1) If the item names match just update the quantity in store_inventory. 2) If new_acquisitions has a new item that does not exist in store_inventory, then add it to the store_inventory. Heres what i have so far but its not very good. I added comments where i need to add taks 1) & 2). Any advice or code would be great, thanks. File new_acq = new File("/src/test/new_acquisitions.csv"); Scanner acq_scan = null; try { acq_scan = new Scanner(new_acq); } catch (FileNotFoundException ex) { Logger.getLogger(mainpage.class.getName()).log(Level.SEVERE, null, ex); } String itemName; int quantity; Double cost; Double price; File store_inv = new File("/src/test/store_inventory.csv"); Scanner invscan = null; try { invscan = new Scanner(store_inv); } catch (FileNotFoundException ex) { Logger.getLogger(mainpage.class.getName()).log(Level.SEVERE, null, ex); } String itemNameInv; int quantityInv; Double costInv; Double priceInv; while (acq_scan.hasNext()) { String line = acq_scan.nextLine(); if (line.charAt(0) == '#') { continue; } String[] split = line.split(","); itemName = split[0]; quantity = Integer.parseInt(split[1]); cost = Double.parseDouble(split[2]); price = Double.parseDouble(split[3]); while(invscan.hasNext()) { String line2 = invscan.nextLine(); if (line2.charAt(0) == '#') { continue; } String[] split2 = line2.split(","); itemNameInv = split2[0]; quantityInv = Integer.parseInt(split2[1]); costInv = Double.parseDouble(split2[2]); priceInv = Double.parseDouble(split2[3]); if(itemName == itemNameInv) { //update quantity } } //add new entry into csv file } Thanks again for any help. =]

• Getting the start address of the current process's heap?

  - by beta

  Hey, I am exploring the lower level workings of the system, and was wondering how malloc determines the start address of the heap. Is the heap a constant offset or is there a call of some sort to get the start address? Does the stack effect the start address of the heap? Thanks, Braden McDorman

• Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

  - by Jascha

  I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

• How do we keep Active Directory resilient across multiple sites?

  - by Alistair Bell

  I handle much of the IT for a company of around 100 people, spread across about five sites worldwide. We're using Active Directory for authentication, mostly served to Linux (CentOS 5) systems via LDAP. We've been suffering through a spate of events where the IP tunnel between the two major sites goes down and the secondary domain controller at one site can't contact the primary domain controller at the other. It seems that the secondary domain controller starts denying user authentication within minutes of losing connectivity to the primary. How do we make the secondary domain controller more resilient to downtime? Is there a way for it to cache the entire directory and/or at least keep enough information locally to survive a multi-hour disconnection? (We're all in a single organizational unit if that makes any difference.) (The servers here are Windows Server 2003; don't assume that we set this up correctly. I'm a software engineer, not an IT specialist.)

• Aggregating / Collecting AJAX requests

  - by Ganesh Shankar

  I have situation where a user can manipulate a large set of data (presented in a table) by using a bunch of filters represented as checkboxes. The page is AJAXed up so the user doesn't have to wait for a full page refresh every time they click a filter. The way it's currently implemented is by having an event handler watch all the checkboxes and request filtered data from the server when a click event is triggered. This works fine. However, there is a usability & performance issue with doing it this way. For example, if a user clicks 6 checkboxes, 6 AJAX requests are triggered and they all come back at various intervals causing the page to be updated 6 times. This will most probably annoy the user and seems rather inefficient. I want to put some kind of timeout on the event handler to do something like this: "Wait for 1 second and if there are no more filters clicked trigger the AJAX request". However, at the moment I've only been able to delay all 6 requests by 1 second. I'm not sure how to aggregate / collect the filter info into 1 AJAX request. Any suggestions would be greatly appreciated!

• Why do browsers allow switching off Javascript?

  - by gath

  Am curious why modern browsers allow switching off Javascript. It's so clear now that to do any substantial modern web application you need to integrate some high level of Javascript, why cant javascript be made an integral part of the browser? It becomes even more annoying especially when this option is OFF by default (IE!!) My opinion is, it should be made a standard for all the browsers to have javascript option enabled by default. What do you guys think?

• Problems with GData Request Token

  - by Dan Delgado

  We have successfully used GData libraries to access a user's Google Docs. But we encountered problems when many users log in to our site and authorize our web app at the same time or successively. Here's what happens: First user successful logs in, authorizes our web app via OAuth and is able to add rubric (or google spreadsheet). Second user, immediately after first user adds a rubric, successfully logs in then webapp fails on authorize (Token not given. I tried to log it.) Third user fails on login. Fourth user was able to log in, authorize via OAuth, and create rubrics successfully. Fifth user was able to log in but like the second user, gets an invalid token on authorize (Token not given.) And the list goes on. Results were unpredicatable. Below is an excerpt of the stack trace we get when the fail scenario happens: Nested in org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException: java.lang.NullPointerException at com.google.gdata.client.authn.oauth.OAuthUtil.normalizeParameters(OAuthUtil.java:158) at com.google.gdata.client.authn.oauth.OAuthUtil.getSignatureBaseString(OAuthUtil.java:81) at com.google.gdata.client.authn.oauth.OAuthHelper.addCommonRequestParameters(OAuthHelper.java:649) at com.google.gdata.client.authn.oauth.OAuthHelper.getOAuthUrl(OAuthHelper.java:592) at com.google.gdata.client.authn.oauth.OAuthHelper.getUnauthorizedRequestToken(OAuthHelper.java:276) at com.projectrix.controller.OAuthController.authorize(OAuthController.java:59) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Method.java:40) Help!

• Full Text Search in SQL Server 2008 shows wrong display_item for Thai language

  - by ensecoz

  I am working with SQL Server 2008. My task is to investigate the issue where FTS cannot find the right result for Thai. First, I have the table which enables the FTS on the column 'ItemName' which is nvarchar. The Catalog is created with the Thai Language. Note that the Thai language is one of the languages that doesn't separate the word by spaces, so '????' '???' '????' are written like this in a sentence: '???????????' In the table, there are many rows that include the word (????); for example row#1 (ItemName: '???????????') On the webpage, I try to search for '????' but SQL Server cannot find it. So I try to investigate it by trying the following query in SQL Server: select * from sys.dm_fts_parser(N'"???????????"', 1054, 0, 0) ...to see how the words are broken. The first one is the text to be broken. The second parameter is to specify that we're using Thai (WorkBreaker, so on). Here is the result: row#1 (display_item: '????', source_item: '???????????') row#2 (display_item: '????', source_item: '???????????') row#3 (display_item: '??', source_item: '???????????') Notice that the first and second row display the wrong display_item '?' in the '????' isn't even Thai characters. '?' in '????' is not a Thai character either. So the question is where did those alien characters come from? I guess this why I cannot search for '????' because the word breaker is broken and keeping the wrong character in the indexes. Please help!

• mysql prevent displaying a row ONE which has reference in another row TWO but no reference in row THREE

  - by Jayapal Chandran

  I have a table like the following id | name | pid 1 | sam | NULL 2 | sams ref | 1 3 | pam | NULL For the first time the first row gets inserted which will have pid as null I insert a row which is related to the first row and then i insert a row which is new and which may be referred by another row in future. now i want only the third row to be displayed and not the first and second row as the second row contains the reference of first row. so if any row has a reference to another row then both the rows should not be displayed. Only rows which is not having any reference should be displayed. BESIDES, IS IT A GOOD PRACTICE? PLEASE ADVICE ON THIS. Edited When i updated in server the query is always giving empty result. here is what i have and this one When pid is NULL then that row should appear but when another entry in the same table with pid as its parent id or any other rows id appears then both the rows should not appear. so if any pid has been referred then both the rows should not appear. here only one row will refer another row and not more than that. in my localhost i have mysql version 5.0.1 or something like that but when i installed xampp in another system it had 5.5 and in the live server it was 5.3 so in version around 5.0 the query is returning rows but in higher versions it is returning empty rows. so now i this case how to make a query?

• Using JUnit as an acceptance test framework

  - by Chris Knight

  OK, so I work for a company who has openly adopted agile practices for development in recent years. Our unit tests and code quality are improving. One area we still are working on is to find what works best for us in the automated acceptance test arena. We want to take our well formed user stories and use these to drive the code in a test driven manner. This will also give us acceptance level tests for each user story which we can then automate. To date, we've tried Fit, Fitnesse and Selenium. Each have their advantages, but we've also had real issues with them as well. With Fit and Fitnesse, we can't help but feel they overcomplicate things and we've had many technical issues using them. The business haven't fully bought in these tools and aren't particularly keen on maintaining the scripts all the time (and aren't big fans of the table style). Selenium is really good, but slow and relies on real time data and resources. One approach we are now considering is the use of the JUnit framework to provide similiar functionality. Rather than testing just a small unit of work using JUnit, why not use it to write a test (using the JUnit framework) to cover an acceptance level swath of the application? I.e. take a new story ("As a user I would like to see basic details of my policy...") and write a test in JUnit which starts executing application code at the point of entry for the policy details link but covers all code and logic down to the stubbed data access layer and back to the point of forwarding to the next page in the application, asserting on what data the user should see on that page. This seems to me to have the following advantages: Simplicity (no additional frameworks required) Zero effort to integrate with our Continuous Integration build server (since it already handles our JUnit tests) Full skillset already present in the team (its just a JUnit test after all) And the downsides being: Less customer involvement (though they are heavily involved in writing the user stories in the first place from which the acceptance tests will be written) Perhaps more difficult to understand (or make understood) the user story and acceptance criteria in a JUnit class verses a freetext specification ala Fit or Fitnesse So, my question is really, have you ever tried this method? Ever considered it? What are your thoughts? What do you like and dislike about this approach? Finally, please only mention alternative frameworks if you can say why you like or dislike them more than this approach.
