  • Server 2008 Active Directory DNS Entries Deleted. Dcdiag unable to contact local AD controller.

    - by Jim Smith
    I've never seen anything like this. At a potential customer site, I noticed that the PC's were all unable to locate the domain controller and netlogon was failing. I fixed the DNS entries on the client PC's so the AD server was DNS server and tried to rejoin the domain. The PC was unable to locate the domain controller. On the server, I checked the DNS settings and while there is the high level AD folder, every single entry related to Active Directory appears to have been completely deleted. There are no backups from what I can tell and this has been happening for 6 months at least. Does anyone have any recommendations for repairing this? Thanks.

  • Best Pattern for AllowUnsafeUpdates

    - by webwires
    So far, in my research I have seen that it is unwise to set AllowUnsafeUpdates on GET request operation to avoid cross site scripting. But, if it is required to allow this, what is the proper way to handle the situation to mitigate any exposure? Here is my best first guess on a reliable pattern if you absolutely need to allow web or site updates on a GET request. Best Practice? protected override void OnLoad(System.EventArgs e) { if(Request.HttpMethod == "POST") { SPUtility.ValidateFormDigest(); // will automatically set AllowSafeUpdates to true } // If not a POST then AllowUnsafeUpdates should be used only // at the point of update and reset immediately after finished // NOTE: Is this true? How is cross-site scripting used on GET // and what mitigates the vulnerability? } // Point of item update SPSecurity.RunWithElevatedPrivledges(delegate() { using(SPSite site = new SPSite(SPContext.Current.Site.Url)) { using (SPWeb web = site.RootWeb) { bool allowUpdates = web.AllowUnsafeUpdates; //store original value web.AllowUnsafeUpdates = true; //... Do something and call Update() ... web.AllowUnsafeUpdates = allowUpdates; //restore original value } } }); Feedback on the best pattern is appreciated.

  • How can i use Google-o-Meter or Google Vizualisation API with Jenkins

    - by kamal
    Here is a sample that displays a static chart: google.load("visualization", "1.0", {packages:["imagechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var dataTable = new google.visualization.DataTable(); dataTable.addColumn('string'); dataTable.addColumn('number'); dataTable.addColumn('string'); // Row data is [chl, data point, point label] dataTable.addRows([ ['January',40,undefined], ['February',60,'Initial recall'], ['March',60,'Product withdrawn'], ['April',45,undefined], ['May',47,'Relaunch'], ['June',75,undefined], ['July',70,undefined], ['August',72,undefined] ]); var options = {cht: 'lc', chds:'0,160', annotationColumns:[{column:2, size:12, type:'flag', priority:'high'},]}; var chart = new google.visualization.ImageChart(document.getElementById('line_div')); chart.draw(dataTable, options); } How can i replace the static values and variables in dataTable.addRows([ with real live data ? In case the compete code is not visible, refer to : http://code.google.com/apis/visualization/documentation/gallery/genericimagechart.html When this Javascript is copied to the "Description" it renders a chart, what i want to know is how to replace the name/value in dataTable.addRows, to the name/values coming from Jenkins

  • Comparing UIColors or CGColor or CGColorSpace

    - by wiznaibus
    I'm having an issue comparing UIColors. I have an image, which I have successfully extracted the color on the image at which the user clicked. Now I want to compare that color with other colors, but I'm getting some strange results. Here's what I've tried: CGColorRef pixelColor = [[buttonImage colorAtPixel:point] CGColor]; UIColor* color = [UIColor colorWithCGColor:pixelColor]; UIColor* aqua = [UIColor colorWithRed:0.521569 green:0.768627 blue:0.254902 alpha:1]; if (CGColorEqualToColor(color.CGColor, aqua.CGColor)) { DLog(@"Apparently, it works"); } DLog(@"%@", color.CGColor); DLog(@"%@", aqua.CGColor); Output: 2011-05-21 19:48:27.144 Coffee[66860:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d1eb80> [<CGColorSpace 0x4d1a070> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) 2011-05-21 19:48:27.145 Coffee[66860:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d1f750> [<CGColorSpace 0x4d1a070> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) It looks like the CGColor addresses are different, but the CGColorSpaces are the same, but I can't figure out how to compare the CGColorSpaces I've also tried this: CGColorRef pixelColor = [[buttonImage colorAtPixel:point] CGColor]; UIColor* color = [UIColor colorWithCGColor:pixelColor]; UIColor* aqua = [UIColor colorWithRed:0.521569 green:0.768627 blue:0.254902 alpha:1]; if ([color isEqual:aqua]) { DLog(@"Apparently, it works"); } DLog(@"%@", color.CGColor); DLog(@"%@", aqua.CGColor); The same silliness occurs. 2011-05-21 20:02:49.277 Coffee[67013:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d3b810> [<CGColorSpace 0x5912010> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) 2011-05-21 20:02:49.278 Coffee[67013:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d3ba20> [<CGColorSpace 0x5912010> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 )`

  • Testing fault tolerant code

    - by Robert
    I’m currently working on a server application were we have agreed to try and maintain a certain level of service. The level of service we want to guaranty is: if a request is accepted by the server and the server sends on an acknowledgement to the client we want to guaranty that the request will happen, even if the server crashes. As requests can be long running and the acknowledgement time needs be short we implement this by persisting the request, then sending an acknowledgement to the client, then carrying out the various actions to fulfill the request. As actions are carried out they too are persisted, so the server knows the state of a request on start up, and there’s also various reconciliation mechanisms with external systems to check the accuracy of our logs. This all seems to work fairly well, but we have difficult saying this with any conviction as we find it very difficult to test our fault tolerant code. So far we’ve come up with two strategies but neither is entirely satisfactory: Have an external process watch the server code and then try and kill it off at what the external process thinks is an appropriate point in the test Add code the application that will cause it to crash a certain know critical points My problem with the first strategy is the external process cannot know the exact state of the application, so we cannot be sure we’re hitting the most problematic points in the code. My problem with the second strategy, although it gives more control over were the fault takes, is I do not like have code to inject faults within my application, even with optional compilation etc. I fear it would be too easy to over look a fault injection point and have it slip into a production environment.

  • How to open embedded Visio files with only Visio Viewer?

    - by Christopher Galpin
    For some bizarre reason Visio Viewer seems incapable of opening vsd files when they're embedded within a (2010) Excel document: However if I open the Excel document with 7-zip, browse to xl\embeddings, extract oleObject1.bin and rename it to a .vsd file extension it opens perfectly fine with Visio Viewer in Internet Explorer. Since this opens fine on a computer with the full Visio installed, my guess is it's trying to launch Visio rather than IE. Is there something I can do to fix this? I've been scanning with Process Monitor and searching with RegScanner comparing a Visio-installed system to a VisioViewer-installed system and there doesn't actually seem to be any sort of registry value giving direction here... maybe it's just the nature of OLE. (If it can't be fixed I'm okay with converting the extracted one to a .png or so to replace the embedded object, but the "solutions" I've found for vsd to image conversion are very poor or non-working, i.e. buggy code, code with Visio dependencies, or online services.)

  • FreeNX 0.7.3 under CentOS 6.3 - Negotiating link parameters

    - by Frank
    since some days I try to get freenx (CentOS package 0.7.3) running under CentOS 6.3. It is like found on many websites: First login is successfull, after that all login attempts fail with the negotiation error. A simple ssh with the same username to the server is successful. For the installation I followed the howTo on http://wiki.centos.org/HowTos/FreeNX Strange is that the changelog of FreeNX 0.7.3 tells that this bug was fixed. Has anybody been successful in running FreeNX under CentOS without this problem and knows how to fix it? Frank

  • Is it possible to write a class that interacts with controls on my WPF form?

    - by Adam S
    Hi all, I'm trying to write a class that I can use to interact with a group of similar controls in my wpf application. I have hit a few roadblocks and now I am wondering if this is a poor approach to begin with. I want to do this primarily to make my code more manageable - I have to interact with around 200 - 300 controls with my code, and it could get very tricky to have all my code in the main window class. Here's something I'd like to be able to do: class ProcControl { private CheckBox * [] Boxes = new CheckBox[10]; ProcControl() { //set boxes 0-9 to point to the actual checkboxes } //provides mass checking/unchecking functionality public void Refactor(CheckBox box) { //see what box it is int box_index = 0; while (Boxes[box_index] != box) { box_index++; } } } This doesn't work as it is right now. I have not figured out how to get my Boxes[] array to point to the actual checkboxes on my form, so I can't interact with them yet. Is it even possible to make an array that points to a bunch of controls so that I may process their properties in a nice manner? Why can't I access the controls at all from inside my class?

  • How to automatically save sessions with multiple windows in FireFox

    - by Matthew Talbert
    I've used primarily FF's built-in session management until recently. Now my needs have become more sophisticated. What I want is to be able to have two windows, one with a fixed set of tabs (approximately 5) and the other with "automatic save". That is, when I start FF, I want 1 window to open with my 5 tabs, and another to open with whatever I had when I shut down FF. I've installed "Session Manager", but I can't seem to get it to do what I want. It will save one window, but when I close one window, it removes that one from the session. Any suggestions to do this with either Session Manager or another plugin would be great.

  • Make VLC play all of a sound clip?

    - by bill weaver
    In VLC 1.0.5, sound files (mp3 and wav) are not playing completely. I think the leading .1 sec and trailing .5 second, more or less, are not playing. I remember this behavior from some years ago, but am not sure the app or how i fixed it. Seems like there was some setting that was causing it to clip the sounds, but can't find or remember it. The Zune Software and Windows Media Player work fine. Windows 7 Pro, if it matters. Any suggestions?

  • Why does a browser dialog come up when an xmlhttprequest sends the wrong / no auth?

    - by Kyle
    How come the major browsers all bring up a login dialog when an xmlhttprequest does auth wrong or doesn't send it? I mean isn't this poor UI? Now a days it seems like a lot of people try http auth in jQuery, because theoretically it is quite easy - until the user fails to enter the correct data and is presented with the browsers dialog, which gets in their way, and they might have no idea what to do with it or why it's there? I don't know too much about these low level browser specifications but can someone bring this up with the RFC or webkit/gecko developers? jQuery digest auth could be powerful and user friendly if this was fixed. ** It seems like apache could also fix the problem on their side by not sending the header, but whichever one is the most secure way of doing this would be nice.

  • is it worth defragging an iPod

    - by alimack
    Essentially my 5G iPod was cutting tracks off and generally misbehaving. So I did the following: 1) Use Diskwarrior - heavy directory fragmentation which it fixed; 2) Use iDefrag - some fragmentation but it kept halting as it couldn't move files; 3) Try to write out drive with Disk Utility - got a warning from DU so gave up before I started; 4) Completely restored using iTunes; 5) Reran Diskwarrior - still heavy directory fragmentation; 6) Reran iDefrag, still fragmentation although limited to two bands; The iPod is much quicker to traverse menus and no more track skipping. My question is this - is defragging worth it or does the heat generated by the process kill the drive and make it a self-defeating process. Anyone have any metrics/ figures? Clearly it's a bad idea for solid state drives like the nano & touch.

  • zabbix monitoring mysql database

    - by krisdigitx

  • Ideas for a rudimentary software licensing implementation

    - by Ross
    I'm trying to decide how to implement a very basic licensing solution for some software I wrote. The software will run on my (hypothetical) clients' machines, with the idea being that the software will immediately quit (with a friendly message) if the client is running it on greater-than-n machines (n being the number of licenses they have purchased). Additionally, the clients are non-tech-savvy to the point where "basic" is good enough. Here is my current design, but given that I have little to no experience in the topic, I wanted to ask SO before I started any development on it: A remote server hosts a MySQL database with a table containing two columns: client-key and license quantity The client-side application connects to the MySQL database on startup, offering it's client-key that I've put into a properties file packaged into the distribution (I would create a new distribution for each new client) Chances are, I'll need a second table to store validation history, so that with some short logic, the software can decide if it can be run on a given machine (maybe a sliding window of n machines using the software per 24 hours) If the software cannot establish a connection to the MySQL database, or decides that it's over the n allowed machines per day, it closes The connection info for the remote server hosting the MySQL database should be hard-coded into the app? (That sounds like a bad idea, but otherwise they could point it to some other always-validates-to-success server) I think that about covers my initial design. The intent being that while it certainly isn't full-proof, I think I've made it at least somewhat difficult to create an easily-sharable cracking solution. Also, I can easily adjust the license amount for a given client/key pair. I gotta figure this has been done a million times before, so tell me about a better solution that's just as simple to implement and provides the same (low) amount of security. In the event that external libraries are used, I prefer Java, as that's what the software has been written in.

  • Updating extra attributes in a has_many, :through relationship using Rails

    - by Robbie
    I've managed to set up a many-to-many relationship between the following models Characters Skills PlayerSkills PlayerSkills, right now, has an attribute that Skills don't normally have: a level. The models look something like this (edited for conciseness): class PlayerSkill < ActiveRecord::Base belongs_to :character belongs_to :skill end class Skill < ActiveRecord::Base has_many :player_skills has_many :characters, :through => :player_skills attr_accessible :name, :description end class Character < ActiveRecord::Base belongs_to :user has_many :player_skills has_many :skills, :through => :player_skills end So nothing too fancy in the models... The controller is also very basic at this point... it's pretty much a stock update action. The form I'm looking to modify is characters#edit. Right now it renders a series of checkboxes which add/remove skills from the characters. This is great, but the whole point of using has_many :through was to track a "level" as well. Here is what I have so far: - form_for @character do |f| = f.error_messages %p = f.label :name %br = f.text_field :name %p = f.label :race %br = f.text_field :race %p = f.label :char_class %br = f.text_field :char_class %p - @skills.each do |skill| = check_box_tag "character[skill_ids][]", skill.id, @character.skills.include?(skill) =h skill.name %br %p = f.submit After it renders "skill.name", I need it to print a text_field that updates player_skill. The problem, of course, is that player_skill may or may not exist! (Depending on if the box was already ticked when you loaded the form!) From everything I've read, has_many :through is great because it allows you to treat the relationship itself as an entity... but I'm completely at a loss as to how to handle the entity in this form. As always, thanks in advance for any and all help you can give me!

  • Apache repeatedly crashing in OS X 10.6.5

    - by ltackett
    I want to be using the system default Apache available through Web Sharing, not MAMP. Other questions/answers related to similar problems have not helped. Initially, I had MAMP running, but I stopped it because I thought it might be causing a conflict, that didn't work. I also had an issue with apachectl related to the 10.6.5 update, which I fixed. Apachectl reports no syntax errors and seems to be working fine to start|stop|restart apache. Here are the errors that repeat. 12/29/10 11:53:28 AM Firewall[63] httpd is listening from ::ffff:0.0.0.0:80 proto=6 12/29/10 11:53:29 AM com.apple.launchd[1] (org.apache.httpd[8618]) Exited with exit code: 1 12/29/10 11:53:29 AM com.apple.launchd[1] (org.apache.httpd) Throttling respawn: Will start in 10 seconds This is not my area of expertise, so I hope that's enough info to go by.

However, when the TV is turned off and then back on I notice there's no sound anymore. There are lots of other people who have this issue aswell. I've found this workaround however it doesn't seem to work for me. I have the newest drivers (12.4). Someone said it was fixed in 9.1 but I still have the issue. Any help is appreciated.

  • Why did this work with Visual C++, but not with gcc?

    - by Carlos Nunez
    I've been working on a senior project for the last several months now, and a major sticking point in our team's development process has been dealing wtih rifts between Visual-C++ and gcc. (Yes, I know we all should have had the same development environment.) Things are about finished up at this point, but I ran into a moderate bug just today that had me wondering whether Visual-C++ is easier on newbies (like me) by design. In one of my headers, there is a function that relies on strtok to chop up a string, do some comparisons and return a string with a similar format. It works a little something like the following: int main() { string a, b, c; //Do stuff with a and b. c = get_string(a,b); } string get_string(string a, string b) { const char * a_ch, b_ch; a_ch = strtok(a.c_str(),","); b_ch = strtok(b.c_str(),","); } strtok is infamous for being great at tokenizing, but equally great at destroying the original string to be tokenized. Thus, when I compiled this with gcc and tried to do anything with a or b, I got unexpected behavior, since the separator used was completely removed in the string. Here's an example in case I'm unclear; if I set a = "Jim,Bob,Mary" and b="Grace,Soo,Hyun", they would be defined as a="JimBobMary" and b="GraceSooHyun" instead of staying the same like I wanted. However, when I compiled this under Visual C++, I got back the original strings and the program executed fine. I tried dynamically allocating memory to the strings and copying them the "standard" way, but the only way that worked was using malloc() and free(), which I hear is discouraged in C++. While I'm curious about that, the real question I have is this: Why did the program work when compiled in VC++, but not with gcc? (This is one of many conflicts that I experienced while trying to make the code cross-platform.) Thanks in advance! -Carlos Nunez

  • In Java, howd do I iterate through lines in a textfile from back to front

    - by rogue780
    Basically I need to take a text file such as : Fred Bernie Henry and be able to read them from the file in the order of Henry Bernie Fred The actual file I'm reading from is 30MB and it would be a less than perfect solution to read the whole file, split it into an array, reverse the array and then go from there. It takes way too long. My specific goal is to find the first occurrence of a string (in this case it's "InitGame") and then return the position beginning of the beginning of that line. I did something like this in python before. My method was to seek to the end of the file - 1024, then read lines until I get to the end, then seek another 1024 from my previous starting point and, by using tell(), I would stop when I got to the previous starting point. So I would read those blocks backwards from the end of the file until I found the text I was looking for. So far, I'm having a heck of a time doing this in Java. Any help would be greatly appreciated and if you live near Baltimore it may even end up with you getting some fresh baked cookies. Thanks!

  • PGP Desktop Whole disk Encryption paused on a toshiba ultrabook z935

    - by garg
    I have a Toshiba z930 Ultrabook with PGP Desktop installed for whole disk encryption. It installed correctly, and started encrypting but it stays paused. If I reboot, it shows me the PGP desktop username, password, domain screen. If I enter in my credentials, it allows me to get into windows but encryption remains paused. If I click on resume, it lets me enter a password, accepts it but then it doesn't do anything. One suspicious thing is that in the 'Select disk or partition to encrypt' box, it says, C: 120B fixed disk. Unknown Bus: TOSHIBA THNSNS12... Do I need to change something in the BIOS, or install any drivers so that it doesn't see it as an Unknown Bus?

  • Calculate total batch upload transfer percent with limited information

    - by GONeale
    Hi there, I have a system which uploads to a server file by file and displays a progress bar on file upload progress, then underneath a second progress bar which I want to indicate percentage of batch complete across all files queued to upload. Information and algorithms I can work out are: Bytes Sent / Total Bytes To Send = First progress bar (eg. 512KB of 1024KB (50%)) That works fine. However supposing I have two other files left to upload, but both file sizes are unknown (as this is only known once the file is about to commence upload, at which point it is compressed and file size is determined) how would I go about making my third progress bar? I didn't think this would be possible as I would need "Total Bytes Sent" / "Total Bytes To Send", to replicate the logic of my first progress bar on a larger scale, however I did get a version working: "Current file number we are on" / "total number of files to send" returning the percentage through the batch, however obviously will not incrementally update and it's pretty crude. So on further thinking I thought if I could incorporate the current file % with this algorithm I could perhaps get the correct progress percentage of my batch's current point. I tried this algorithm, but alas to no such avail (sorry to any math heads, it's probably quite apparent why it won't work) ("Current file number we are on" / "total number of files to send") * ("Bytes Sent" / "Total Bytes To Send") For example I thought I was on the right track when testing with this example: 2/3 (2nd of 3rd file) = 66% (this is right so far) but then when I added * 0.20 (for indicating only 20% of 2nd file has uploaded) we went back to 13%. What I need is only a little over 33%! I did try the inverse at 0.80 and a (2/3 * (2/3 * 0.2)) Can this be done without knowing entire bytes in batch to upload? Please help! Thank you!

  • Metro Apps on Win 8 aren't working with static ip behind auth proxy

    - by Kamal
    In Windows 8 Professional, Metro Apps and Windows Update do not work on static IP settings behind authenticated proxy server. They work on DHCP on the same proxy settings. (We have DHCP for wifi and static IP for LAN, both using the same proxy server). IE, Chrome and other desktop apps work nicely on both. Metro apps worked on an auth proxy (DHCP only), when I changed their proxy settings from the 'edit group policy' option. (StartSettingsEdit Group PolicyComputer ConfigurationAdministrative TemplatesNetwork IsolationInternet Proxy for Apps) Can this be fixed?

  • Strange strace and setuid behaviour: permission denied under strace, but not running normally.

    This is related to this question. I have a script (fix-permissions.sh) that fixes some file permissions: #! /bin/bash sudo chown -R person:group /path/ sudo chmod -R g+rw /path/ And a small c program to run this, which is setuided: #include "sys/types.h" #include "unistd.h" int main(){ setuid(geteuid()); return system("/path/fix-permissions.sh"); } Directory: -rwsr-xr-x 1 root root 7228 Feb 19 17:33 fix-permissions -rwx--x--x 1 root root 112 Feb 19 13:38 fix-permissions.sh If I do this, everything seems fine, and the permissions do get correctly fixed: james $ sudo su someone-else someone-else $ ./fix-permissions but if I use strace, I get: someone-else $ strace ./fix-permissions /bin/bash: /path/fix-permissions.sh: Permission denied It's interesting to note that I get the same permission denied error with an identical setup (permissions, c program), but a different script, even when not using strace. Is this some kind of heureustic magic behaviour in setuid that I'm uncovering? How should I figure out what's going on? System is Ubuntu 10.04.2 LTS, Linux 2.6.32.26-kvm-i386-20101122 #1 SMP

  • Clicking hyperlinks in Email messages becomes painfully slow

    - by Joel Spolsky
    Running Windows 7 (RC, 64 bit). Suddenly, today, after months without a problem, clicking on links has become extremely slow. I've noticed this in two places. (1) clicking hyperlinks in Outlook email messages, which launches Firefox, takes around a minute. Launching Firefox by itself is instantaneous - I have an SSD drive and a very fast CPU. (2) opening Word documents attached to Outlook email messages also takes a surprisingly long time. The only thing these two might have in common is that they use the DDE mechanism, if I'm not mistaken, to send a DDE open command to the application. Under Windows XP this problem could sometimes be fixed by unchecking the "Use DDE" checkbox in the file type mapping, however, I can't find any equivalent under Windows 7. See here for someone else having what I believe is the same problem. See here for more evidence that it's DDE being super-super-slow.
