  • DotNetNuke will not save from editor

    - by Staffan
    A DNN site version 05.02.00(275) When editing a HTML module the following happens: If I make the changes and save before the cookie "portalaliasid" expires (within 1 minute) all is well. BUT if I stay in the editor for a longer time, say 2 minutes, and posting I end up at the editor again with the old content. All my previous work is lost. Now I'm lost - is this a bug, a bad setting or what? /Staffan

  • How can I make clean search urls?

    - by newbie
    If I have search that has a lot of different options, then url becomes very long and looks very bad. Is there anyway to make urls look better? Using POST to make search would keep urls clean, but people couldn't share search urls.

  • How to crop scanned image using C#?

    - by ieaglle
    I have a scanned image of a book page and i need to crop this scan for leaving only page area. I tried to use AForge to detect page borders, but it doesn't work because the space which i need to crop may consist of little "light" areas (due to scanner quality) and edge detector detects borders there. That's why this is bad idea as for me. Could you recommend something? P.S. Please don't tell me to use non-free libraries.

  • Will wear induced by turning computers off in the evening be offset by energy savings?

    - by sharptooth
    I'm asking this here because this is primarily a huge office scenario and administrators will more likely have the answer I'm looking for. Employees' desktop computers can be either left turned on for the whole night or switched off in the evening and turned back on in the morning. The latter will surely save energy. In the same time turning on and off is very harmful for the equipment - hardware often breaks specifically when turned on. Both energy and hardware replacements cost money. With energy it's quite obvious - you pay every month according to what your power meter shows. With hardware replacements it's worse - you need qualified stuff to quickly diagnose the problems and once something breaks the affected employee will have to wait for some time while his computer is fixed/replaced and the data is recovered. So the company has to choose between saving money on energy and saving money on computer maintaince and lost hours. Such decisions must be well though. Is there any detailed study of how turning computers off each evening affects their lifetime?

  • How ZFS handles online replacement in a RAID-Z (theoretical)

    - by Kevin
    This is a somewhat theoretical question about ZFS and RAID-Z. I'll use a three disk single-parity array as an example for clarity, but the problem can be extended to any number of disks and any parity. Suppose we have disks A, B, and C in the pool, and that it is clean. Suppose now that we physically add disk D with the intention of replacing disk C, and that disk C is still functioning correctly and is only being replaced out of preventive maintenance. Some admins might just yank C and install D, which is a little more organized as devices need not change IDs - however this does leave the array degraded temporarily and so for this example suppose we install D without offlining or removing C. Solaris docs indicate that we can replace a disk without first offlining it, using a command such as: zpool replace pool C D This should cause a resilvering onto D. Let us say that resilvering proceeds "downwards" along a "cursor." (I don't know the actual terminology used in the internal implementation.) Suppose now that midways through the resilvering, disk A fails. In theory, this should be recoverable, as above the cursor B and D contain sufficient parity and below the cursor B and C contain sufficient parity. However, whether or not this is actually recoverable depnds upon internal design decisions in ZFS which I am not aware of (and which the manual doesn't say in certain terms). If ZFS continues to send writes to C below the cursor, then we are fine. If, however, ZFS internally treats C as though it were gone, resilvering D only from parity between A and B and only writing A and B below the cursor, then we're toast. Some experimenting could answer this question but I was hoping maybe someone on here already knows which way ZFS handles this situation. Thank you in advance for any insight!

  • XMLTask 1.16: Does it work with Ant so far?

    - by noelg103
    I'm trying to use XMLTask 1.16, but, unfortunately, I got error, java.lang.UnsupportedClassVersionError: Bad version number in .class file, all the time. But if I switch back to XMLTask 1.15, it work fine. Does anyone know how to make XMLTask 1.16 work with Ant.

  • Code golf - hex to (raw) binary conversion

    - by Alnitak
    In response to this question asking about hex to (raw) binary conversion, a comment suggested that it could be solved in "5-10 lines of C, or any other language." I'm sure that for (some) scripting languages that could be achieved, and would like to see how. Can we prove that comment true, for C, too? NB: this doesn't mean hex to ASCII binary - specifically the output should be a raw octet stream corresponding to the input ASCII hex. Also, the input parser should skip/ignore white space. edit (by Brian Campbell) May I propose the following rules, for consistency? Feel free to edit or delete these if you don't think these are helpful, but I think that since there has been some discussion of how certain cases should work, some clarification would be helpful. The program must read from stdin and write to stdout (we could also allow reading from and writing to files passed in on the command line, but I can't imagine that would be shorter in any language than stdin and stdout) The program must use only packages included with your base, standard language distribution. In the case of C/C++, this means their respective standard libraries, and not POSIX. The program must compile or run without any special options passed to the compiler or interpreter (so, 'gcc myprog.c' or 'python myprog.py' or 'ruby myprog.rb' are OK, while 'ruby -rscanf myprog.rb' is not allowed; requiring/importing modules counts against your character count). The program should read integer bytes represented by pairs of adjacent hexadecimal digits (upper, lower, or mixed case), optionally separated by whitespace, and write the corresponding bytes to output. Each pair of hexadecimal digits is written with most significant nibble first. The behavior of the program on invalid input (characters besides [a-fA-F \t\r\n], spaces separating the two characters in an individual byte, an odd number of hex digits in the input) is undefined; any behavior (other than actively damaging the user's computer or something) on bad input is acceptable (throwing an error, stopping output, ignoring bad characters, treating a single character as the value of one byte, are all OK) The program may write no additional bytes to output. Code is scored by fewest total bytes in the source file. (Or, if we wanted to be more true to the original challenge, the score would be based on lowest number of lines of code; I would impose an 80 character limit per line in that case, since otherwise you'd get a bunch of ties for 1 line).

  • How to change X and Y of a button

    - by Driss Zouak
    I'm using MonoTouch. When I rotate to LandscapeRight/Left I want to change the location of some of my buttons but I'm not having any success. I'm replacing the button.Bounds with a new rectangleF and setting that value in the WillRotate, but that's not working. I am returning true in my ShouldAutorotateToInterfaceOrientation handler. In principal what I'm trying to do is allow as much as possible to automatically rotate but then fix a couple of buttons that end up in a bad place.

  • Who are good suppliers of .NET 4 Hosted Virtual Private Servers ? (May 2010)

    - by Nick Haslam
    I'm looking for a supplier for hosting a Virtual server, running Windows Server 2008 (R2 ideally) and .NET 4 to run an internet facing ASP.NET web application. I'd also like to be able to remote desktop onto it, and install other apps as necessary, including other websites as and when. I'm based in the UK, so a UK based supplier would be great. I was looking at Fasthosts, but having researched them a bit more, they look like a bad idea.

  • appendTo() inside $.each in jquery seems to cause flicker....

    - by Pandiya Chendur
    appendTo() causes flicker when it is inside $.each.... $.each(jsob.Table, function(i, employee) { $('<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>').appendTo('#ResultsDiv'); }); Right now i am appending every new div to #ResultsDiv inside$.each is it good/bad to do so... If it is bad What can be done to make my divs appendTo() after the loop so that i it wont flicker.... EDIT:(based on answer) var divs = ''; $.each(jsob.Table, function(i, employee) { divs += '<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>'; }); $("#ResultsDiv").append(divs); But that too doesn't stop the flicker...

  • unit test for proxy checking

    - by zubin71
    Proxy configuration of a machine can be easily fetched using def check_proxy(): import urllib2 http_proxy = urllib2.getproxies().get('http') I need to write a test for the above written function. In order to do that I need to:- Set the system-wide proxy to an invalid URL during the test(sounds like a bad idea). Supply an invalid URL to http_proxy. How can I achieve either of the above?

  • Setting up a linked server to another server which isn't in a domain without using SQL authenticatio

    - by Telos
    Server A (SQL2005) is in our primary domain, but server B (SQL2000) is just in a windows workgroup. We are not allowed to join it to the domain, or bad things happen... We also can't enable SQL authentication on server B. We've got domain accounts for A, and matching local accounts on server B. I can connect to B from my local PC or A using SSMS and a domain login, but I can't get the linked server to connect. Any ideas how to do this?

  • How can I get a file's size in C?

    - by Nino
    How can I find out the size of a file? I opened with an application written in C. I would like to know the size, because I want to put the content of the loaded file into a string, which I alloc using malloc(). Just writing malloc(10000*sizeof(char)); is IMHO a bad idea.

  • mounting ext4 fs with block size of 65536

  • What's an appropriate HTTP status code to return by a REST API service for a validation failure?

    - by michaeljoseph
    I'm currently returning 401 Unauthorized whenever I encounter a validation failure in my Django/Piston based REST API application. Having had a look at the HTTP Status Code Registry I'm not convinced that this is an appropriate code for a validation failure, what do y'all recommend? 400 Bad Request 401 Unauthorized 403 Forbidden 405 Method Not Allowed 406 Not Acceptable 412 Precondition Failed 417 Expectation Failed 422 Unprocessable Entity 424 Failed Dependency Update: "Validation failure" above means an application level data validation failure ie. incorrectly specified datetime, bogus email address etc.

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • Play animation (storyboard) backwards

    - by drasto
    Is there a simple way to play some StoryBoad backward (reversed) ? As there is a method Storyboard.Begin() I would expect that there is some method like "Storyboard.BeginReversed()" but I cannot find it. If there is no way to play an animation backwards that I have to write for most of my animations complementary animations. That smells bad to me (code duplication of some kind). Basically I just animate a Grid that shows and than hides.

  • How to force emacs to use \n instead of \r\n

    - by User1
    I have to use windows to write some shell scripts. I decided to use emacs, but I get a weird error when running the script: /bin/bash^M: bad interpreter: No such file or directory Correct me if I'm wrong, but that looks like the shebang ends in \r\n instead of just \n. How can I tell emacs to only write \n? I'm in Shell-script major mode. It's quite surprising this isn't fixed by default.
