  • Somewhat newb question about assy and the heap.

    - by Eric M
    Ultimately I am just trying to figure out how to dynamically allocate heap memory from within assembly. If I call Linux sbrk() from assembly code, can I use the address returned as I would use an address of a statically (ie in the .data section of my program listing) declared chunk of memory? I know Linux uses the hardware MMU if present, so I am not sure if what sbrk returns is a 'raw' pointer to real RAM, or is it a cooked pointer to RAM that may be modified by Linux's VM system? I read this: How are sbrk/brk implemented in Linux?. I suspect I can not use the return value from sbrk() without worry: the MMU fault on access-non-allocated-address must cause the VM to alter the real location in RAM being addressed. Thus assy, not linked against libc or what-have-you, would not know the address has changed. Does this make sense, or am I out to lunch?

  • SSRS Issue: Rounding to nearest .25

    - by D.R.
    I have an SSRS (2008) report that takes in a raw transactions, then groups and totals them. At the "Total" level, I would like to round the final numbers to the nearest .25, however I cannot find a method to do this. According to what I've read, the Round() function in SSRS only rounds to integers. I have found a couple ways to do it in SQL, but the problem is, I want to do all the calculations with the REAL numbers and just round the result so that I don't introduce a significant amount of error from the real numbers. Here's the best SQL solution I could find: dec(round(number * 4, 0)/4,11,2) as Nearest_Qtr Anyone know how I could do the equivalent in the actual SSRS report? Thanks in advance for the help!

  • How to make flyspell bypass some words by context?

    - by manu
    Hi, I use Emacs for writing most of my writings. I write using reStructuredText, and then transform them to LaTeX after some preprocessing since I write my citations á-la LaTeX. This is an excerpt of one of my texts (in Spanish): En \cite[pp.~XXVIII--XXIX]{Crnkovic2002} se brindan algunos riesgos que se pueden asumir con el desarrollo basado en componentes, los This text is processed by some custom scripts that deals with the \cite part so rst2latex can do its job. When I activate flyspell-mode it signals most of the citation keys as spelling errors. How can I tell flyspell not to spellcheck things within \cite commands. Furthermore, how can I combine rst-mode and flyspell, so that rst-mode would keep flyspell from spellchecking the following? reST comments reST code literal reST directive parameters and arguments reST raw directive contents Any ideas?

  • Single-Page Web Apps: Client-side datastores & server persistence

    - by fig-gnuton
    How should client-side datastores & persistence be handled in a single-page web application? Global vars vs. DI/IoC: Should datastores be assigned to global variables so any part of the application can access them? Or should they be dependency injected where required? Server persistence: Assuming a datastore's data needn't always be persisted to the server immediately, should the datastore itself handle persistence? If not, then what class should handle persistence and how should the persistence class fit into the client-side architecture overall? Is the datastore considered the model in MVC, or is it something else since it just stores raw data?

  • Why do I get corrupt output on my file?

    - by Martin
    I have a simple program which I have compiled in both MinGW and Visual C++ 2008 Express, and both give an output file larger than 88200. When I set s = 0, both programs work as expected. What am I doing wrong? #include <fstream> using namespace std; int main(int argc, char *argv[]) { int i; short s; fstream f; f.open("test.raw", ios_base::out); for(i = 0; i < 44100; i++) { s = i & 0xFFFF; // PROBLEM? f.write(reinterpret_cast<const char *>(&s), sizeof(s)); } f.close(); return 0; }

  • How to assign a PHP variable that contains a mixed of PHP and html elements?

    - by Rick
    I have a PHP page that contains html and tags and PHP codes and I am using AJAX to manipulate some data and now I need to spit out the response but I am not sure if it is possible to put the mixed content into a string variable to pass through... Is this possible? For example I need to: $response = "<p>some text--<?php echo $something; ?>"; Thanks... To clear things up, I am not trying to send raw PHP code to clientside as that would be silly and won't be evaluated as it is a server side script. I am just looking for a fast way to put everything into a variable without manually re-doing the whole page stripping out the php open and close tags and echos...etc

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

  • Treeview Slow in IE?!?!

    - by Mike
    I have a treeview with around 200 records that needs to be fully expanded at all times (so no loading on demand). It is inside of an update panel with the updatemode set to conditional. There are other update panels on the page as well that are set to conditional. Depending on user actions the tree may need to be rebuilt by calling databind and updating the updatepanel. Everything works fine in firefox, longest postback about 2 seconds. With IE I have to wait up to 30 seconds sometimes and the action may have nothing to do with the tree just changing a dropdown in its own updatepanel takes forever. I have considered the size of viewstate and just raw HTML generated may be causing the delay but wouldn't that effect both browsers? Anyone have anyideas what is making it so slow in IE??? Thanks!

  • Is a PHP-only "cache engine" ever worth it?

    - by adsads
    I wrote a rather small skeleton for my web apps and thought that I would also add a small cache for it. It is rather simple: If the current page exists as a file in the cache and the file isn't too old, read it out and exit instead of rebuilding the page If the current page isn't cached/outdated recalc the page and save it However, the bad thing about it is: My performance tests with a page that receives 40 relatively long posts via a MySQL query said that with using the cache, it took even longer to handle a single request (1000 tests each) How can that happen? Should I just remove the complete raw-PHP cache and relieve on the availability of some PHP cache like memcached or so?

  • How can I communicate between Windows 8 and WP8 apps using ssl?

    - by Clay Shannon
    I'm considering using either raw notifications (WNS) or sockets for communication between a Windows 8 and WP8 app. I've found some samples for using sockets but my question[s] here are: does WP8 support sending/receiving messages over ssl and, if so, how is it done? Something I need to be true or find a workaround for is that the Windows 8 app has a permanent IPAddress to which the phone app will send its updates. Typically, a tablet will be running Windows 8 app, always listening for incoming messages; the phone app will periodically send messages.

  • MS Access vs SQL Server and others ? Is it worth taking a db server when less than 2 Gb and only 20

    - by asksuperuser
    After my experiment with MSAccess vs MySQL which shows MS Access hugely overperforming Mysql odbc insert by a factor 1000% before I would do the same experiment with SQL Server I searched for some other's people and found this one: http://blog.nkadesign.com/2009/access-vs-sql-server-some-stats-part-1/ which says "As a side note, in this particular test, Access offers much better raw performance than SQL Server. In more complex scenarios it’s very likely that Access’ performance would degrade more than SQL Server, but it’s nice to see that Access isn’t a sloth." So is worth bother with some db server when data is less than 2 Gb and users are about 20 (knowing that MS Access theorically supports up to 255 concurrent users though practically it's around a dozen concurrent users only). Are there any real world studies that really compare MS Access with other db in these specific use case ? Because professionaly speaking I keep hearing people systematically recommend DB server from people who have never used Access just because they think DB Server can only perform better in every case which I used to think myself I confess.

  • CSS not displayed depending on page

    - by Kanjiroushi
    I have a friend that has a really strange issue with my website. When he clicks on http://www.copeo.fr/ the page displays fine but when he clicks on a link like www.copeo.fr/user/ the CSS is not applied even after a refresh. The raw html does display. I asked him to display the CSS that is hosted on amazon S3 hcopeoressources.s3.amazonaws.com/style/futurvert/style.css and it displays fine. The code validates on W3C validator so does the CSS. I am lost what could be the origin of the issue. Could it be its enterprise cache? configuration of IE7 on his machine? If it happens to someone else who could explain the issue to me, I am all hears. Thanks

  • Spring & Hibernate SessionFactory - recovery from a down server

    - by MJB
    So pre spring, we used version of HibernateUtil that cached the SessionFactory instance if a successful raw JDBC connection was made, and threw SQLException otherwise. This allowed us to recover from initial setup of the SessionFactory being "bad" due to authentication or server connection issues. We moved to Spring and wired things in a more or less classic way with the LocalSessionFactoryBean, the C3P0 datasource, and various dao classes which have the SessionFactory injected. Now, if the SQL server appears to not be up when the web app runs, the web app never recovers. All access to the dao methods blow up because a null sessionfactory gets injected. (once the sessionfactory is made properly, the connection pool mostly handles the up/down status of the sql server fine, so recovery is possible) Now, the dao methods are wired by default to be singletons, and we could change them to prototype. I don't think that will fix the matter though - I believe the LocalSessionFactoryBean is now "stuck" and caches the null reference (I haven't tested this yet, though, I'll shamefully admit). This has to be an issue that concerns people.

  • Django - raw_id_fields title not refreshing.

    - by James Howell
    Hi, I am currently having an issue when using the raw_id_field within admin.py in my Django project. My site's admin area has a number of image upload fields for various different model pages which are all ForeignKey fields to an Image model where all images for the site are stored. As the site will eventually be dealing with a large quantity of images (100s, maybe 1000s) the default select box would be unusable. I created various admin.ModelAdmin classes e.g class InfoSlideAdmin(admin.ModelAdmin): raw_id_fields=('image',) These change the image selector within my Edit pages from a Select Box to a Raw ID Field. However when I select a different image using this control although the ID of the new image is shown the title from the previous image still displays. Any ideas?

  • Is there a way to send text to an aspcontrol via jquery

    - by Garrith Graham
    Is there a way to send data to an aspcontrol say a label called label1? Via jquery? I know jquery only likes html but is there a way to just send the raw text to an asp control using a similar method below: <script type="text/javascript"> $(document).ready(function () { var label = $("#<%= testLabel.ClientID %>"); var div = $("<div></div>").html("content").attr('id', 'test'); var serializer = new XMLSerializer(); label.text(serializer.serializeToString(div)); }); </script>

  • Merging tables in MySQL - sum up columns

    - by Alan Williamson
    I have an interesting problem, that i am sure has a simple answer, but i can't seem to find it in the docs. I have two separate database tables, on different servers. They are both identical table schema with the same primary keys. I want to merge the tables together on one server. But, if the row on Server1.Table1 exists in Server2.Table2 then sum up the totals in the columns i specify. Table1{ column_pk, counter }; "test1", 3 "test2", 4 Table2{ column_pk, counter }; "test1", 5 "test2", 6 So after i merge i want: "test1",8 "test2",10 Basically i need to do a mysqldump but instead of it kicking out raw INSERT statements, i need to do a INSERT..ON DUPLICATE KEY UPDATE statements. What are my options? Appreciate any input, thank you

  • Manipulating both unicode and ASCII character set in C#

    - by Murlex
    I have this mapping in my C# application string [,] unicode2Ascii = { { "&#3001;", "\x86" } }; ஹ - is the unicode value for a tamil literal "ஹ". This is the raw hex literal for the unicode value saved by MS Word as a byte sequence. I am trying to map these unicode value "strings" to a hex value under 255 (so as to accommodate non-unicode supported systems). I trying to use string.replace like this: S = S.replace(unicode2Ascii[0,0], unicode2Ascii[0,1]); However the resultant ouput has a ? instead of the actual hex 0x86 stored. Any pointer on how I could set the encoding for the second element of that array to something like windows-1252? Or is there a better way to do this conversion? thanks in advance

  • FastCGI, PHP, Sendmail, and Codeigniter

    - by Kyle J. Dye
    Hi Everyone. I am experiencing an odd issue. I just switched to FastCGI (Apache) because of the big performance boost. Everything is working great, except when I attempt to use sendmail (Codeigniter Class or just raw PHP). I have tested with and without CI and still get a 500 internal server error when trying to send. Could this be getting caused by a discrepency in how FastCGI utilizes sendmail? Has anyone else experienced this issue? Also, the email will send, it just errors afterwards. Please let me know a solution if you have one! Thanks! :)

  • write cache and write sequence order

    - by excanoe
    ok, here i have some weird question: let say we have some binary file (.log), and sequence of write operations, for example log1, log2, log3 and each has some block size n (raw data). question: can I be sure that log1,log2 and log3 sequences can be written in the correct order in ONE file, even if i have few cache levels (disk hardware and os level)? update very interested in what will be with records order (not with records) if we have software or hardware failure (reboot or another reason). update there can be some percent of write failures, but main question is: will write order stay correct?

  • SQL Query to select upcoming events with a start and end date

    - by Chris T
    I need to display upcoming events from a database. The problem is when I use the query I'm currently using any events with a start day that has passed will show up lower on the list of upcoming events regardless of the fact that they are current My table (yaml): columns: title: type: string(255) notnull: true default: Untitled Event start_time: type: time end_time: type: time start_day: type: date notnull: true end_day: type: date description: type: string(500) default: This event has no description category_id: integer My query (doctrine): $results = Doctrine_Query::create() ->from("sfEventItem e, e.Category c") ->select("e.title, e.start_day, e.description, e.category_id, e.slug") ->addSelect("c.title, c.slug") ->orderBy("e.start_day, e.start_time, e.title") ->limit(5) ->execute(array(), Doctrine_Core::HYDRATE_ARRAY); Basically I'd like any events that is currently going on (so if today is in between start_day and end_day) to be at the top of the list. How would I go about doing this if it's even possible? Raw sql queries are good answers too because they're pretty easy to turn into DQL.

  • How to solve this Java type safety warning? (Struts2)

    - by Nicolas Raoul
    Map session = ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: The method put(Object, Object) belongs to the raw type Map. References to generic type Map should be parameterized. Map<String, Serializable> session = (Map<String, Serializable>)ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: Unchecked cast from Map to Map. The getSession method belongs to Struts2 so I can't modify it. I would like to avoid using @SuppressWarnings because other warnings can be useful. I guess all Struts2 users in the world faced the same problem... is there an elegant solution?

  • Inconsistent Behavior From Declared DLL Function

    Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load).
