  • NHibernate: inserting additional calculated column

    - by Andrey Shchekin
    What would be your approach with NHibernate to do the following: When Comment is inserted into DB, and its property Text is inserted into column Text (due to a mapping), insert into column TextHash a hash of this property value. It seems trivial if I map TextHash, but how should I do this without mapping it? I do not need it in the domain model, its a DB-level optimization (I would use computed HashBytes if not for the length limit).

  • How to make emacs properly indent if-then-else construct in elisp

    - by Mad Wombat
    When I indent if-then-else construct in emacs lisp, the else block doesn't indent properly. What I get is: (defun swank-clojure-decygwinify (path) "Convert path from CYGWIN UNIX style to Windows style" (if (swank-clojure-cygwin) (replace-regexp-in-string "\n" "" (shell-command-to-string (concat "cygpath -w " path))) (path))) where else form is not indented at the same level as the then form. Is there an obvious way to fix this?

  • Hosting a VST/DX instrument in C#/C++?

    - by James D
    I'm trying to get a read on the effort level involved in building a barebones virtual instrument host in C++ or C# but I haven't been able to get any hard information. Does anybody know any good starter apps, tutorials, helper libraries for this sort of thing? If it matters, the goal would be to a) accept incoming MIDI events and b) dispatch them to the virtual instrument. In C++ or C#, if possible. Thanks!

  • How do you setLayoutParams() for an ImageView?

    - by DeadTime
    I want to set the LayoutParams for an ImageView but cant seem to find out the proper way to do it. I can only find documentation in the API for the various ViewGroups, but not an ImageView. Yet the ImageView seems to have this functionality. This code doesn't work... myImageView.setLayoutParams(new ImageView.LayoutParams(30,30)); How do I do it?

  • LaTeX not compiling properly

    - by celenius
    I'm using TeXshop, Natbib, Hyperef and two-column layout, and I am getting the following message: \pdfendlink ended up in different nesting level than \pdfstartlink which prevents LaTeX from compiling. I've searched online for solutions, but most of them are from a few years back, and I don't understand them. Is there anything I should be doing to prevent this error? It appears to be happening due to where the pagebreaks are occurring. Examples of solutions 1, 2

  • JavaScript: What would cause setInterval to stop firing?

    - by Rosarch
    I am writing a chat AJAX app. Randomly, in FF 3.5.9, setInterval() seems to stop firing. I don't have clearInterval() anywhere in my code. What could be causing this to happen? $(document).ready(function () { $("#no-js-warning").empty(); messageRefresher = new MessageRefresher(0); setInterval($.proxy(messageRefresher, "refresh"), 2000); }); function notifyInRoom(user) { $.getJSON('API/users_in_room', { room_id: $.getUrlVar('key'), username: user }, function (users) { if (!$.isEmptyObject(users)) { $("#users").empty(); $.each(users, function (index, username) { var newChild = sprintf("<li>%s</li>", username); $("#users").append(newChild); }); } else { $("#users-loading-msg").text("No one is in this room."); } }); } function MessageRefresher(latest_mid) { this._latest_mid = latest_mid; } MessageRefresher.prototype.refresh = function () { notifyInRoom($("#user-name").val()); var refresher = this; $.getJSON('API/read_messages', { room_id: $.getUrlVar('key'), mid: refresher._latest_mid }, function (messages) { if (! (messages == null || $.isEmptyObject(messages[0]))) { // messages will always be at least [[], [], 0] $("#messages-loading-msg").hide(); for (var i = 0; i < messages[0].length; i++) { var newChild = sprintf('<li><span class="username">%s:</span> %s</li>', messages[1][i], messages[0][i]); $("#messages").append(newChild); } refresher._latest_mid = messages[2]; setUserBlockClass(); } else { $("#messages-loading-msg").text("No messages here. Say anything..."); } }); } // Give the end-user-block class to the appropriate messages // eg, those where the next message is by a different user function setUserBlockClass() { $("#messages li").each(function (index) { if ($(this).children(".username").text() != $(this).next().children(".username").text()) { $(this).addClass("end-user-block"); } }); } I checked the most recent responses in Firebug, and it was the same responses that had been sent earlier. (So, it's not like an unusual response caused a crash.) If I refresh the page, the calls resume.

  • Understanding VS2010 C# parallel profiling results

    - by Haggai
    I have a program with many independent computations so I decided to parallelize it. I use Parallel.For/Each. The results were okay for a dual-core machine - CPU utilization of about 80%-90% most of the time. However, with a dual Xeon machine (i.e. 8 cores) I get only about 30%-40% CPU utilization, although the program spends quite a lot of time (sometimes more than 10 seconds) on the parallel sections, and I see it employs about 20-30 more threads in those sections compared to serial sections. Each thread takes more than 1 second to complete, so I see no reason for them to work in parallel - unless there is a synchronization problem. I used the built-in profiler of VS2010, and the results are strange. Even though I use locks only in one place, the profiler reports that about 85% of the program's time is spent on synchronization (also 5-7% sleep, 5-7% execution, under 1% IO). The locked code is only a cache (a dictionary) get/add: bool esn_found; lock (lock_load_esn) esn_found = cache.TryGetValue(st, out esn); if(!esn_found) { esn = pData.esa_inv_idx.esa[term_idx]; esn.populate(pData.esa_inv_idx.datafile); lock (lock_load_esn) { if (!cache.ContainsKey(st)) cache.Add(st, esn); } } lock_load_esn is a static member of the class of type Object. esn.populate reads from a file using a separate StreamReader for each thread. However, when I press the Synchronization button to see what causes the most delay, I see that the profiler reports lines which are function entrance lines, and doesn't report the locked sections themselves. It doesn't even report the function that contains the above code (reminder - the only lock in the program) as part of the blocking profile with noise level 2%. With noise level at 0% it reports all the functions of the program, which I don't understand why they count as blocking synchronizations. So my question is - what is going on here? How can it be that 85% of the time is spent on synchronization? How do I find out what really is the problem with the parallel sections of my program? Thanks.

  • Which is generally considered faster or best practice: symlinks or Apache aliases?

    - by Christopher W. Allen-Poole
    I'm curious as to what most people's views are on this subject. Personally, I will almost always prefer symlinks unless I have no other option -- I find that it is far more obvious when someone is navigating the file system, but, on the other hand aliasing is more platform independent. Windows XP, for example, doesn't have anything remotely comparable to symlinks (NTFS junctions are not interpreted correctly by at least some environments), which means that anything which relies on symlinks in a *nix based system cannot be transferred. (I know that Windows 64x OS's have symlinks, but I've not seen if they can be read correctly by the environments previously mentioned) In addition to this, I was also wondering which is considered faster. Is this even possible to know? Do you have a conjecture? I would imagine that since symlinks are generally more low-level than Apache it would make sense that they would be referenced faster, but, on the other hand, I would guess that Apache is required to do a lookup in either case so it would be disk read dependent.

  • How do I get Windows 7 wallpaper to display the company logo properly?

    - by David Silva Smith
    Windows 7 is not displaying our company background properly. Curves show pixelation and straight lines are jagged. I'm working with a scalable vector graphics (SVG) image that I've exported to the same resolution (pixel dimensions, to be technical) as the desktop, which is 1440x900. I have tried exporting the image as a .png, .jpg, and .bmp. All of these look correct in an image viewing program, such as Windows Photo Viewer and Paint, but when I set the Windows background to these images, curves show pixelation and straight lines are jagged. Reading online, it seems that behind the scenes, Windows is converting the image to a .jpg with low quality compression, which is causing the issue. I've tried setting the image as a background through Internet Explorer, saving it as a .jpg, and putting the file in the Windows photo directory as suggested in some online forums, but none of those solutions have fixed my issue.

  • How divide a string into array

    - by Ricky
    If I have the following plain string, how do I divide it into an array of three elements? {["a","English"],["b","US"],["c","Chinese"]} ["a","English"],["b","US"],["c","Chinese"] This problem is related to JSON string parsing, so I wonder if there is any API to facilitate the conversion.

  • HPC Cluster planning workflow?

    - by Veronica
    After three days of intensive Google searching, I have not found any high-level workflow of how to build a low profile - cheap - computing cluster (we are not interested in HA yet). This is just a front-end plus a node for now. We want to start small with rockscluster, provide a web-based server for offering services, and then add nodes as our budget increases. We're small company, so we haven't enough human resources to implement it smoothly. Here are some facts about our environment: Our hardware is not constant (we will add nodes). Our workload will vary (in the order from 200Mb - 1Tb) Our software will change (scientific applications for data mining) Do you know any visual workflow, worksheet, chart, describing the general necessary steps to begin our cluster planning?

  • Handles and pointer to object

    - by Tony
    I have a python Interpreter written in C++, the PyRun_String function from the Python API is said to return a handle, however in my code I have it assigned to pointer to a PyObject? PyObject* presult = PyRun_String(code, parse_mode, dict, dict); Is this actually correct? Can you implicitly cast this handle to this object pointer? Should it not be a HANDLE instead?

  • flex coverflow adding links to the images

    - by nivcaner
    Hi, I'm using sebastiaan holtrop's cover flow component in Flex. I would like to be able to add the sources to the images using xml. I would also like each image to have its own URL assosiated with it, so when I click it (if it's in the front of the coverflow), I go to that URL. I'm a bit clueless as to how to get that done (this is the first time I use Flex and the project docs think I'm a higher level Flex programmer...). Thanks, Niv

  • How to manage preventive maintenance planning for external IT support?

    - by code-gijoe
    I am a bit puzzled by the way to handle server upgrade planning for software we maintain on remote sites. This is my case: I work for a software company that has many external clients. We are trying to be more Agile in our development so we plan to release small improvements every quarter and we wish to keep our clients informed of maintenance schedules. Instead of having angry clients that believe there ROI of our support plan is low, we want to be more proactive. Lets say we have 100 machines to take care of, is there some tool to assist me in planing the maintenance with clients? Right now I get a call from a client that is unhappy requesting we upgrade them, that is when we go into panic mode and start making calls. That is when I need to check my calendar, coordinate with the other guys, call a few times, change the date again and again until everyone is happy. Can this be done better?

in names(SOdata)[-c(1,7)]) { p<- magic(i) ggsave(paste("magig_plot_",i,".png",sep=""), plot=p, height=3.5, width=5.5) } The problem is that sometimes in the call to geom_point the subset returns an empty dataframe, which sometimes (!) causes ggplot2 to plot all the data instead of none of the data. geom_point(data = SOdata[SOdata[[y]] > high,], position=position_jitter(w=0.1, h=0),col="green", alpha=0.5)+ This is kindda of important to me, and I am really stuck trying to find a solution. Any help that will get me started is much appreciated. Thanks in advance.

  • Google map in jsp document

    - by Todd
    Hi, I am trying to implement google map api into one of my web page which is generated by jsp document, and I am having trouble getting it work. I found some jsp taglibrary by www.lamatek.com/GoogleMaps, but it doesn't seem to work.(I mean even examples on their web site don't work) Has anyone done work on google map in jsp document? I can really use some help or advice.(It seems like jsp docuemnt and javascript just don't get along) p.s I can get static google map work, but that's not my client wants.

  • Perform action based on load avg

    - by sfx
    I'm running some web applications on an debian server and have to struggle with ddos attacks sometimes. It's eating up all my resources and I can't ssh anymore into the server. An idea was to drop all connections if the load avg is too high, so there are still resources for me and accept new connections if the load avg is low enough. Since this has to work under heavy load I'm afraid a cronjob wouldn't be fast enough or take too much resources. tl;dr: Is there a way to configure the behavior if the load avg is above a specific threshold?
