  • jQuery UI blind effect - reveal from bottom

    - by ronnie burns
    This could be really obvious and I'm completely missing it. I've searched for hours and can't seem to find a way to, using jQuery, reveal a hidden div from the bottom up. What I am trying to achieve is exactly as in the following link, but in reverse: http://jqueryui.com/demos/show/ I can slide a div from the bottom to the top, but this reveals itself as it moves, rather than being 'masked' in. Like I said, this could (should?) be really obvious and I'm not seeing it, but I've been looking for ages and can't find a solution to this relatively simple problem. Thanks, Ronnie

  • jQuery AJAX with two domains

    - by Andrew Burns
    OK here is the situation: I have an externally hosted CMS which works great for 99% of our needs. However on the more advanced things I inject my own CSS+JS and do magic. The problem I am running into is loading a simple HTML page from jQuery.ajax() calls. It appears to work in the sense that no warnings or errors are thrown; however in my success handler (which IS ran), the response is blank! I have been scratching my head for the whole morning trying to figure this out and the only thing I can think of is that is has something to do with the cross domain issue (even though it appears to work). Injected JavaScript: $(document).ready(function() { doui(); }); function doui() { $.ajax({ url: 'http://apps.natronacounty-wy.gov/css/feecalc/ui.htm', cache: false, success: ajax_createUI, charset: "utf-8", error: function(e) { alert(e); } }); } function ajax_createUI(data, textStatus) { alert(data); $("#ajax-content").html(data); } My ajax_createUI() success handler is called and textStatus is "success"; however data is empty. This JS file resides @ http://apps.natronacounty-wy.gov/css/js/feecalc.js however the CMS website (which gets the JS injected into it) resides @ http://www.natronacounty-wy.gov/ Am I just being stupid or is it a bug that it looks like it should be working but isn't?

  • For Loop help In a Hash Cracker Homework.

    - by aaron burns
    On the homework I am working on we are making a hash cracker. I am implementing it so as to have my cracker. java call worker.java. Worker.java implements Runnable. Worker is to take the start and end of a list of char, the hash it is to crack, and the max length of the password that made the hash. I know I want to do a loop in run() BUT I cannot think of how I would do it so it would go to the given max pasword length. I have posted the code I have so far. Any directions or areas I should look into.... I thought there was a way to do this with a certain way to write the loop but I don't know or can't find the correct syntax. Oh.. also. In main I divide up so x amount of threads can be chosen and I know that as of write now it only works for an even number of the 40 possible char given. package HashCracker; import java.util.*; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class Cracker { // Array of chars used to produce strings public static final char[] CHARS = "abcdefghijklmnopqrstuvwxyz0123456789.,-!".toCharArray(); public static final int numOfChar=40; /* Given a byte[] array, produces a hex String, such as "234a6f". with 2 chars for each byte in the array. (provided code) */ public static String hexToString(byte[] bytes) { StringBuffer buff = new StringBuffer(); for (int i=0; i<bytes.length; i++) { int val = bytes[i]; val = val & 0xff; // remove higher bits, sign if (val<16) buff.append('0'); // leading 0 buff.append(Integer.toString(val, 16)); } return buff.toString(); } /* Given a string of hex byte values such as "24a26f", creates a byte[] array of those values, one byte value -128..127 for each 2 chars. (provided code) */ public static byte[] hexToArray(String hex) { byte[] result = new byte[hex.length()/2]; for (int i=0; i<hex.length(); i+=2) { result[i/2] = (byte) Integer.parseInt(hex.substring(i, i+2), 16); } return result; } public static void main(String args[]) throws NoSuchAlgorithmException { if(args.length==1)//Hash Maker { //create a byte array , meassage digestand put password into it //and get out a hash value printed to the screen using provided methods. byte[] myByteArray=args[0].getBytes(); MessageDigest hasher=MessageDigest.getInstance("SHA-1"); hasher.update(myByteArray); byte[] digestedByte=hasher.digest(); String hashValue=Cracker.hexToString(digestedByte); System.out.println(hashValue); } else//Hash Cracker { ArrayList<Thread> myRunnables=new ArrayList<Thread>(); int numOfThreads = Integer.parseInt(args[2]); int charPerThread=Cracker.numOfChar/numOfThreads; int start=0; int end=charPerThread-1; for(int i=0; i<numOfThreads; i++) { //creates, stores and starts threads. Runnable tempWorker=new Worker(start, end, args[1], Integer.parseInt(args[1])); Thread temp=new Thread(tempWorker); myRunnables.add(temp); temp.start(); start=end+1; end=end+charPerThread; } } } import java.util.*; public class Worker implements Runnable{ private int charStart; private int charEnd; private String Hash2Crack; private int maxLength; public Worker(int start, int end, String hashValue, int maxPWlength) { charStart=start; charEnd=end; Hash2Crack=hashValue; maxLength=maxPWlength; } public void run() { byte[] myHash2Crack_=Cracker.hexToArray(Hash2Crack); for(int i=charStart; i<charEnd+1; i++) { Cracker.numOfChar[i]////// this is where I am stuck. } } }

  • Uncatchable errors in node.js

    - by Peter Burns
    So I'm trying to write a simple TCP socket server that broadcasts information to all connected clients. So when a user connects, they get added to the list of clients, and when the stream emits the close event, they get removed from the client list. This works well, except that sometimes I'm sending a message just as a user disconnects. I've tried wrapping stream.write() in a try/catch block, but no luck. It seems like the error is uncatchable.

  • I'm trying to run a command using WMI.

    - by MIchael Burns
    This is my code: a button is clicked and the text in a textbox is taken for the remotePC. I can run it locally but when I try to run it remotely it will not work, I think it has something to do with using WMI to run a shared file? public void IPXFER(string RemotePC) { object[] theProcessToRun = { @"\\network-share\ipxfer\ipxfer.exe -s corp-trend -p 1234 -m 1 -c 12345" }; ConnectionOptions theConnection = new ConnectionOptions(); theConnection.Impersonation = ImpersonationLevel.Impersonate; theConnection.EnablePrivileges = true; ManagementScope theScope = new ManagementScope("\\\\" + RemotePC + "\\root\\cimv2", theConnection); ManagementClass theClass = new ManagementClass(theScope, new ManagementPath("Win32_Process"), new ObjectGetOptions()); theClass.InvokeMethod("Create", theProcessToRun); }

  • How to query an .NET assembly's required framework (not CLR) version?

    - by Bonfire Burns
    Hi, we are using some kind of plug-in architecture in one of our products (based on .NET). We have to consider our customers or even 3rd party devs writing plug-ins for the product. The plug-ins will be .NET assemblies that are loaded by our product at run-time. We have no control about the quality or capabilities of the external plug-ins (apart from checking whether they implement the correct interfaces). So we need to implement some kind of safety check while loading the plug-ins to make sure that our product (and the hosting environment) can actually host the plug-in or deliver a meaningful error message ("The plug-in your are loading needs .NET version 42.42 - the hosting system is only on version 33.33."). Ideally the plug-ins would do this check internally, but our experience regarding their competence is so-so and in any case our product will get the blame, so we want to make sure that this "just works". Requiring the plug-in developers to provide the info in the metadata or to explicitly provide the information in the interface is considered "too complicated". I know about the Assembly.ImageRuntimeVersion property. But to my knowledge this tells me only the needed CLR version, not the framework version. And I don't want to check all of the assembly's dependencies and match them against a table of "framework version vs. available assemblies". Do you have any ideas how to solve this in a simple and maintainable fashion? Thanks & regards, Bon

  • Flame Experiments Aboard the ISS Yield Surprising Results

    - by Jason Fitzpatrick
    Recent flame-based experiments aboard the International Space Station yielded results scientists simply thought couldn’t happen–combustion in microgravity is a curious thing. Smithsonian magazine reports on the findings: Here on Earth, when a flame burns, it heats the surrounding atmosphere, causing the air to expand and become less dense. The pull of gravity draws colder, denser air down to the base of the flame, displacing the hot air, which rises. This convection process feeds fresh oxygen to the fire, which burns until it runs out of fuel. The upward flow of air is what gives a flame its teardrop shape and causes it to flicker. But odd things happen in space, where gravity loses its grip on solids, liquids and gases. Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow. “If you ignite a piece of paper in microgravity, the fire will just slowly creep along from one end to the other,” says Dietrich. “Astronauts are all very excited to do our experiments because space fires really do look quite alien.” Hit up the link below for the full article including how NASA is applying the findings.

  • How do I enable SQLite on Linux/Apache/PHP?

    - by Edward Tanguay
    To enable SQLite on my Windows/Apache/PHP setup, I uncomment the following lines in the php.ini file and restart Apache: extension=php_pdo.dll extension=php_pdo_sqlite.dll Now I have a VPS with Suse Linux 10.3 and Apache/PHP was set automatically. Looking through the php.ini file to make the above changes, I see that things are a little different on Linux: there is no list of extensions to uncomment I found "extension_dir = /usr/lib/php5/extensions" but in this directory find only: pdo.so pdo_mysql.so How can I enable SQLite in this Linux environment?

  • Why would Firefox not be able to visit Google anymore?

    - by Edward Tanguay
    Lately I've noticed that my Firefox Browser was taking a long time when I would search Google, e.g. 3 seconds before I would see any results. If I search for a three-word phrase, it just hangs trying to connect: I removed all add-ons but it still does this. I thought it might be something with my router, but Chrome, Safari, Opera and Internet Explorer all work fine. Bing works fine in Firefox. Here's my Firefox version information: Otherwise I can still use Firefox, e.g. I'm using it to post this question, but I do notice that when I browse with it, images are often "broken" for a split second before they appear, as if it is having a hard time pulling them from a remote server. Other browsers don't do this. What could be causing Firefox to hang when searching Google?

  • Troubleshooting Windows Explorer

    - by edward.r.cox
    I have a .NET application that receives messages from a web server and alerts the user. I have one Windows XP SP3 computer that when my application receives the message, it crashes the Windows Explorer shell. (I can see the message received in the listview just before Explorer crashes.) I don't see any errors in the Windows event logs. Is there somewhere that I should be looking at to troubleshoot this problem?

  • How can I play an online video in full screen AND type in a text editor at the same time?

    - by Edward Tanguay
    I watch instructional videos that play in Silverlight such as the ones at http://windowsclient.net/learn. I watch them in full screen on my left monitor. While the video is playing, I want to be able to type notes in a text editor on my right monitor. However, as soon as I press a key, the video exits full screen mode. How can I force the Silverlight player to stay in full screen mode even as I type in another application?

  • Is there a test to see if hardware virtualization (vmx / xvm) are presently enabled within a Linux session?

    - by Dr. Edward Morbius
    I'm writing procedures for configuring VirtualBox support for 64-bit SMP guests, which requires hardware virtualization suppot (VTx/Intel, AMD-V/AMD). I have successfully configured this myself, however I'd like the procedure to be clear. sed -ne '/^flags/s/^.*: //p' /proc/cpuinfo | egrep -q '(vmx|svm)' && echo Has hardware virt || echo No HW virt ... shows if the CPU is capable. I've still got to go enable the feature in BIOS. Any way to test from within Linux to see that this is no or not? Thanks.

  • Can Mac KeyNote presentations exported for Windows be shown in good quality and be edited?

    - by Edward Tanguay
    A friend asked me this: ...I stopped using KeyNote for one simple reason – contrary to the Mac marketing blurb, the final presentations do NOT work fine on Windows PCs – they look distorted and have formatting quirks which cannot be corrected because the Windows/Powerpoint file it has supposedly been saved as is in fact a non-editable file, kind of like a pdf. Is there a way to create Mac KeyNote presentation files so they look nice on Windows and can be edited?

  • Can someone explain RAID-0 in plain English?

    - by Edward Tanguay
    I've heard about and read about RAID throughout the years and understand it theoretically as a way to help e.g. server PCs reduce the chance of data loss, but now I am buying a new PC which I want to be as fast as possible and have learned that having two drives can considerably increase the perceived performance of your machine. In the question Recommendations for hard drive performance boost, the author says he is going to RAID-0 two 7200 RPM drives together. What does this mean in practical terms for me with Windows 7 installed, e.g. can I buy two drives, go into the device manager and "raid-0 them together"? I am not a network administrator or a hardware guy, I'm just a developer who is going to have a computer store build me a super fast machine next week. I can read the wikipedia page on RAID but it is just way too many trees and not enough forest to help me build a faster PC: RAID-0: "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Because there is no redundancy, this level is not actually a Redundant Array of Inexpensive Disks, i.e. not true RAID. However, because of the similarities to RAID (especially the need for a controller to distribute data across multiple disks), simple strip sets are normally referred to as RAID 0. Any disk failure destroys the array, which has greater consequences with more disks in the array (at a minimum, catastrophic data loss is twice as severe compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss. So in plain English, how can "RAID-0" help me build a faster Windows-7 PC that I am going to order next week?

  • Where is the "fix" button on Windows 7 Photo Viewer?

  • Why would image thumbnails not be showing in all search engines in all browsers?

    - by Edward Tanguay
    For over a week now, when I search for a word at Google, it correctly gives me some preview image thumbnails: But when I click on "images", it doesn't show me any thumbnails: The same thing happens at Bing.com, when I search Bing itself it gives me some thumbnails on the general search result page: But when I click on "images", it doesn't show me any thumbnails: The same thing happens at Yahoo: If I click on one of the broken thumbnails, it shows me the picture fine: Thumbnails at youtube also work fine: It seems each search engine is hanging on different URLs as shown above: t1.gstatic.com ts3.mm.bing.net thm-a02.yimg.com so it doesn't seem to be the problem of one specific URL not sending thumbnails, it is just a problem with search engine image thumbnails in general. Also, this happens in every browser I try: Explorer, Firefox, Chrome. What could be the problem? Is it my computer, some setting somewhere, my router, my Internet provider (T-Online, Germany)? Has anyone ever had this problem and solved it?

  • How do I configure Thunderbird to locally remap the label-folder in an G-Mail IMAP account?

    - by Edward Beach
    I'm using G-Mail and Thunderbird together for an imap account. One of the limitations of G-Mail is that there's no concept of nested labels - which is fine when I'm using the account through the web interface but when I'm using Thunderbird I would like a bit more organization. Is there a way for Thunderbird to locally remap an imap folder's path? For example with a "MyCustomLabel" label: Thunderbird: "MyAccount/path/on/local/machine/MyCustomLabel" G-Mail: "MyCustomLabel" Thanks

  • What is the easiest way to get a yyyy-mm-dd hh:mm:ss timestamp hotkey on the Mac?

    - by Edward Tanguay
    On Windows I use the PSPad editor which has a nice ALT-D timestamp which you can edit the format of, e.g. yyyy-mm-dd hh:mm:ss. When working outside an editor, e.g. Google Docs, I have Autohotkey which I have programmed CTRL-D to insert a yyyy-mm-dd hh:mm:ss timestamp. I am now working on a Mac mostly using TextWrangler as my editor but I can't find a timestamp hotkey in its features. What is the easiest way to get a yyyy-mm-dd hh:mm:ss hotkey on Mac, either in a (free) text editor or a (free) autohotkey equivalent?

  • T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading

    Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the vga output works. symptom: Screen blanks / no display but works on second monitor steps to reproduce: - boot - wait (it does not matter what you do you do not have to login or anything) - (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noice of about 10 seconds) - right after the sounds ends the monitor gets black times seem to be the same each time. software: installed no new software before/after, running zone alarm and antivirus. other: it does not feel hot in any place, there dont seem to be running processes with strange behaviour. warranty: out of warranty what was i doing: typing text on a website and doing some php coding in a text editor. Anyone any idea what I can do here other than buy a new laptop? / does it sound familiar to known cases? update: * exactly the same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-Screen-Blackout/m-p/288772 and the second poster (garyj) here: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Black-Screen-on-T60/m-p/235053#M48627 and here: "i have that same problem. i replaced the CCRL on mine and it works fine when the screen is not screwed in. once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black.

Now the LCD. Which does not seem the core isse but some electric issue so it seems replacing the LCD is not the thing todo here. I have the following question: If it is not the LCD that needs to be replaced (see other threads) which parts can I order to fix this? Has anyone got any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense?
