• need to add secure ftp file upload area to a client's website

  - by user346602

  This is a variation on a previous question as I am having tons of trouble finding answers in all my relentless online searches. Am designing a website for an architecture firm. They want their clients to be able to upload files to them, through a link on their site, via ftp. They also want to have a sign in for their clients, and ensure the uploads are secure. I can figure out how to make a form that has a file upload area - but just don't understand the ftp and the secure part... I understand html, css and a bit of JQuery; the rest is still very challenging to me. Have found something called net2ftp that claims to do what I'm looking for - but the even the installation instructions (for administrators, here: http://www.net2ftp.com/help.html) confuse me. Do I need a MySQL database? Where do I put in Admin password they refer to? It goes on... Is there anything "easier" out there that anyone knows of? I have read that I should be Googling "file managers" - but don't know if these can be embedded in a client's website. I even need to understand of what happens to said file, and where it ends up, when client clicks the upload link. Oh - I am so in over head on this one.

• Trying to find a PHP5 API-based embeddable CMS

  - by StrangeElement

  I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

• Oracle DBMS_PROFILER only shows Anonymous in the results tables

  - by Greg Reynolds

  I am new to DBMS_PROFILER. All the examples I have seen use a simple top-level procedure to demonstrate the use of the profiler, and from there get all the line numbers etc. I deploy all code in packages, and I am having great difficulty getting my profile session to populate the plsql_profiler_units with useful data. Most of my runs look like this: RUNID RUN_COMMENT UNIT_OWNER UNIT_NAME SECS PERCEN ----- ----------- ----------- -------------- ------- ------ 5 Test <anonymous> <anonymous> .00 2.1 Profiler 5 Test <anonymous> <anonymous> .00 2.1 Profiler 5 Test <anonymous> <anonymous> .00 2.1 Profiler I have just embedded the calls to the dbms_profiler.start_profiler, flush_data and stop_profiler as per all the examples. The main difference is that my code is in a package, and calls in to other package. Do you have to profile every single stored procedure in your call stack? If so that makes this tool a little useless! I have checked http://www.dba-oracle.com/t_plsql_dbms_profiler.htm for hints, among other similar sites.

• how to access anti aliasing method of a font with CSS

  - by Daniel Ramirez-Escudero

  I've had this problem in a lot of different webs. You have a font which has different anti-aliasing options, the designer uses the same font with different anti-aliasing options on different parts of the text on the web. So there is a difference between some elements. In this case I have sharp, crisp, strong and smooth. I've used a font generator to get the code to access it via @font-face. Even so, I also have the original .otf if important to know. Is there a method to access this? I upload a picture of what I mean and my actual code: ![@font-face { font-family: 'light'; src: url('../_fnt/light/gothamrnd-light.eot'); src: url('../_fnt/light/gothamrnd-light.eot?#iefix') format('embedded-opentype'), url('../_fnt/light/gothamrnd-light.woff') format('woff'), url('../_fnt/light/gothamrnd-light.ttf') format('truetype'), url('../_fnt/light/gothamrnd-light.svg#../_fnt/light/gothamrnd-light') format('svg'); font-weight: normal; font-style: normal; }]![enter image description here][1]

• Why ntp settle time toe long?

  - by fercis

  I simply try to set-up NTP to my system. Both server and clients will run on my computer which are linked together with local link. One of them will have the reference clock. Both the server and Client are linux Ubuntu. I install ntp daemon to both sides. In clients, I enter the ip address of the server to /etc/ntp.conf. Everything works fine. However, the setting of the time to correct time in client side takes too long time (around 17 minutes). Is it possible to gather correct time just at startup. I write some code that regularly calls "ntpdate " by system call and the problem is solved but there has to be something that allows me to decrease the poll time of the client to 1-2 minutes. There are some settings as maxpoll - minpoll in ntp.conf, but I couldn't manage to understand their function, because with the best configuration (minpoll 4? 16 seconds?) I also cannot see that client side corrects its time before 10 minutes. In addition, in some cases my client is an embedded system (ARM - IGEP board) and it always opens with an irrelevant date (2-3 years ago). So the time that takes to correct the time should not depend on the time difference also.

• Emailing an excel sheet with SSL in Python

  - by jakecar

  Hi...this is my first post so let me know if there are any common courtesies I should know about. I just started programming 8 months ago, so I am fairly new. I have been doing some projects to get better. A project I'm working on now creates an Excel sheet from inputted data. It's in Python, which I just started learning a couple of weeks ago. I'm attempting to embed part of this Excel sheet into an email, sent from my school address. I have spent hours looking this up, and to no avail. There are two problems I am asking for help with: 1) I have figured out how to send an email from my GMail account, but not from my school address. My school email uses SSL port 465, which I have tried to use, but to no avail. Unfortunately, I have been having a problem setting up outgoing email for this account on my iPhone as well. It may be related? Does anyone know of common issues relating to outgoing email with SSL and Python? 2) Excel has an option of saving a sheet as a HTML. When doing so, I copy and pasted the HTML source and emailed it as an attachment. Unfortunately, the colored text did not transfer over. Does anyone know of a better way of using Python to send an excel sheet embedded in an email? Thanks for your help!

• What are the fastest-performing options for a read-only, unordered collection of unique strings?

  - by Dan Tao

  Disclaimer: I realize the totally obvious answer to this question is HashSet<string>. It is absurdly fast, it is unordered, and its values are unique. But I'm just wondering, because HashSet<T> is a mutable class, so it has Add, Remove, etc.; and so I am not sure if the underlying data structure that makes these operations possible makes certain performance sacrifices when it comes to read operations -- in particular, I'm concerned with Contains. Basically, I'm wondering what are the absolute fastest-performing data structures in existence that can supply a Contains method for objects of type string. Within or outside of the .NET framework itself. I'm interested in all kinds of answers, regardless of their limitations. For example I can imagine that some structure might be restricted to strings of a certain length, or may be optimized depending on the problem domain (e.g., range of possible input values), etc. If it exists, I want to hear about it. One last thing: I'm not restricting this to read-only data structures. Obviously any read-write data structure could be embedded inside a read-only wrapper. The only reason I even mentioned the word "read-only" is that I don't have any requirement for a data structure to allow adding, removing, etc. If it has those functions, though, I won't complain.

• Problem writing a snippet containing Emacs Lisp code

  - by user388346

  Hi all, I've been trying to make use of a cool feature of YASnippet: write snippets containing embedded Emacs Lisp code. There is a snippet for rst-mode that surrounds the entered text with "=" that is as long as the text such as in ==== Text ==== Based on this snippet, I decided to slightly modify it (with Elisp) so that it comments out these three lines depending on the major mode you are in (I thought that such a snippet would be useful to organize the source code). So I wrote this: ${1:`(insert comment-start)`} ${2:$(make-string (string-width text) ?\-)} $1 ${2:Text} $1 ${2:$(make-string (string-width text) ?\-)} $0 This code works relatively well except for one problem: the indentation of these three lines gets mixed up, depending on the major mode I'm in (e.g., in emacs-lisp-mode, the second and the third lines move more to the right than the first line). I think the source of the problem might have something to do with what comes after the string ${1: on the first line. If I add a character, I have no problem (i.e., all three lines are correctly aligned at the end of the snippet expansion). If I add a single space after this string, the misalignment problem still continues though. So my question is: do you know of any way of rewriting this snippet so that this misalignment does not arise? Do you know what's the source of this behaviour? Cheers,

• Why would I use Assembly.LoadFile in lieu of Assembly.LoadFrom?

  - by Cheeso

  It's my impression that Assembly.LoadFrom uses the ApplicationBase and PrivateBinPath. It also my impression that Assembly.LoadFile does not. Why would anyone want to use LoadFile? In other words, if my understanding is correct, why would anyone want to NOT use the ApplicationBase and PrivateBinPath? I'm working with some existing code, which uses LoadFile, and I don't understand why it would do so. LoadFile apparently does not load dependencies from the same directory. The LoadFrom method does load dependencies (From the doc: The load-from context...allows dependencies on that path to be found and loaded because the path information is maintained by the context.) I'd like to convert it from using LoadFile, to use LoadFrom. What is likely to break, if anything, if I replace LoadFile with LoadFrom? Even if it iss benign, it may be that I cannot do the replacement, just based on project schedules. If I cannot replace LoadFile with LoadFrom, is there a way to convince assemblies loaded with LoadFile to load dependencies? Is there a packaging trick I can use (embedded assembly, ILMerge, an AssemblyResolve event, something like that) that can allow an assembly loaded with LoadFile to also load its dependencies?

• Modelling deterministic and nondeterministic data separately

  - by Superstringcheese

  I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

• Change Powerpoint chart data with .NET

  - by mc6688

  I have a Powerpoint template that contains 1 slide and on that slide is a chart. I'd like to be able to manipulate that charts data using .NET. So far I have code that... unzips the Powerpoint file. unzips the embedded excel file (ppt\embeddings\Microsoft_Office_Excel_Worksheet1.xlsx) It successfully manipulates the data in the excel sheet and zips it back up. Opens and manipulates ppt\charts\chart1.xml Powerpoint is then zipped up and delivered to the user The result of this is a Powerpoint file that shows a blank chart. But when I click on the chart and go to edit data it updates the data and shows the correct chart. I believe my problem is with the chart1.xml that I am generating. I have compared my generated version with a version created by Powerpoint and they are almost identical. The only differences are in the values for <c:crossAx> and <c:axId>. There are also some rounding difference in the data. But I do not feel like that would result in an blank chart. Is there another file that I need to edit? Does anyone have any ideas as to what else I should try to get this working?

• Failure remediation strategy for File I/O

  - by Brett

  I'm doing buffered IO into a file, both read and write. I'm using fopen(), fseeko(), standard ANSI C file I/O functions. In all cases, I'm writing to a standard local file on a disk. How often do these file I/O operations fail, and what should the strategy be for failures? I'm not exactly looking for stats, but I'm looking for a general purpose statement on how far I should go to handle error conditions. For instance, I think everyone recognizes that malloc() could and probably will fail someday on some user's machine and the developer should check for a NULL being returned, but there is no great remediation strategy since it probably means the system is out of memory. At least, this seems to be the approach taken with malloc() on desktop systems, embedded systems are different. Likewise, is it worth reattempting a file I/O operation, or should I just consider a failure to be basically unrecoverable, etc. I would appreciate some code samples demonstrating proper usage, or a library guide reference that indicates how this is to be handled. Any other data is, of course, welcome.

• Generated HTML word document not displaying image correctly

  - by spiderdijon

  I'm trying to add an image to a generated html word document that is embedded in a classic ASP page. The code looks something like this: <% Response.ContentType = "application/msword" %> <html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word"> ... <v:shape id="_x0000_s1030" type="#_x0000_t75" style='position:absolute; left:0;text-align:left;margin-left:0;margin-top:17.95pt;width:7in;height:116.85pt; z-index:2;mso-position-horizontal:center;mso-position-horizontal-relative:page; mso-position-vertical-relative:page'> <v:imagedata src="http://xxx/image001.gif" o:title="image001"/> <w:wrap anchorx="page" anchory="page"/> <w:anchorlock/> </v:shape><![endif]--><![if !vml]><span style='mso-ignore:vglayout;position: absolute;z-index:0;left:0px;margin-left:0px;margin-top:24px;width:672px; height:156px'><img width=672 height=156 src="http://xxx/image001.gif" v:shapes="_x0000_s1030"></span><![endif]> The image URL is correct and can be viewed through a browser, however when the word document opens, the image has a red x, with the error message: The image cannot be displayed. Your computer may not have enough memory to open the image, or the image may be corrupted. Restart your computer, and then open the file again. If the red x still appears, you may have to delete the image and then insert it again. If i copy the html code and try to open the word document on my local machine, it displays the image correctly. It just doesn't work when retrieving the document from the server. This happens for any images I try to add. Is there another way to add images to html-generated word documents that can be output from an asp page? Thanks.

• How To Share Information Between Django and Javascript?

  - by Randy

  So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

• Youtube video on load through Jquery/JS

  - by jonthecoder2346

  My goal is to display a youtube video through a javascript function that will read the embedded code and load the video automatically in the div assigned. But I am not getting anything shown in the div assigned for the video. Is it because it has to be triggered by a button click? <script type="text/javascript"> var last_cnad_text_1 = ''; var options_cnad_text_1 = { embedMethod:'fill', maxWidth:320, maxHeight: 320 }; function loadVideo() { val = $('#cnad_text_1').val(); if ( val != '' && val != last_cnad_text_1 ) { last_cnad_text_1 = val; $("#embed_cnad_text_1").oembed(val,options_cnad_text_1); } } $(function(){ $('#cnad_text_1').keydown(loadVideo()); $('#cnad_text_1').click(loadVideo()); $('#cnad_text_1').change(loadVideo()); }); </script> <body> <input id="cnad_text_1" type="text" value="" size="60" name="cnad[text_1]"> <div id="embed_cnad_text_1"></div> </body> </html>

• asp.net mvc stand alone ascx control how do i link (css and js) most efficiently

  - by Julian

  Hi, I need some advice. I have developed some asp.net mvc web pages. Each page has a master and some ascx controls (between 2 - 6) embedded into it a js and css file. Up to now every thing was fine. In order to improve modularity, flexibility and testability the ascx's are now expected to be able to work as stand alone controls. (Each ascx has also got its own css and js files in some cases it has another control inside it) In order to meet this requirement we call the controller with the relevant parameters and it returns the ascx (partial) directly to the browser without all of the other parts of the original page . In order to get it to display correctly (css) and act correctly (js/jquery) all of the relevant files need to be added (as links or scripts eg. href="<%= ResolveUrl(styleSheet)%>") to the user control. This is "contradicting" the concept of positioning the files at the most logical place (could be the master page for example). How can I overcome this problem? Keep in mind that this is relevant for each "control" ascx file. Any thoughts will be appreciated.

• How do I make my program run with different privileges at Windows 7 startup?

  - by iira

  Hi, I am trying to add my program run in Windows 7 startup, but it doesn't work. My program has an embedded UAC manifest. My current way is by adding a string value at HKCU..\Run. I found a manual solution for Vista from http://social.technet.microsoft.com/Forums/en/w7itprosecurity/thread/81c3c1f2-0169-493a-8f87-d300ea708ecf Click Start, right click on Computer and choose “Manage”. Click “Task Scheduler” on the left panel. Click “Create Task” on the right panel. Type a name for the task. Check “Run with highest privileges”. Click Actions tab. Click “New…”. Browse to the program in the “Program/script” box. Click OK. On desktop, right click, choose New and click “Shortcut”. In the box type: schtasks.exe /run /tn TaskName where TaskName is the name of task you put in on the basics tab and click next. Type a name for the shortcut and click Finish. Additionally, you need to run the saved scheduled task shortcut to run the program instead of running the application shortcut to ignore the IAC prompt. When startup the system will run the program via the original shortcut. Therefore you need to change the location to run the saved task. Please: Open Regedit. Find the entry of the startup item in Registry. It will be stored in one of the following branches. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run HKEY_USERS.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run Double-click on the correct key, change the path to the saved scheduled task you created. Is there any free code to add item with privileges option in scheduled task? I haven't found the free one in torry.net. Thanks a lot.

• XmlDocument.Load() throws XmlSchemaValidationException

  - by Praetorian

  Hi, I'm trying to validate an XML document against a schema (which is embedded in my program as a resource). I got everything to work, so I tried to test for errors by adding a second sibling node in the XML at a location where the schema specifies maxOccurs="1". The problem is that my ValidationEventHandler is never getting called, also XmlDocument.Load() is throwing an XmlSchemaValidationException exception when I'd expected XmlDocument.Validate() to do that. This is the code I have: private void ValidateUserData( string xmlPath ) { var resInfo = Application.GetResourceStream( new Uri( @"MySchema.xsd", UriKind.Relative ) ); var schema = XmlSchema.Read( resInfo.Stream, SchemaValidationCallBack ); XmlSchemaSet schemaSet = new XmlSchemaSet(); schemaSet.Add( schema ); schemaSet.ValidationEventHandler += SchemaValidationCallBack; XmlReaderSettings settings = new XmlReaderSettings(); settings.Schemas = schemaSet; settings.ValidationType = ValidationType.Schema; XmlDocument doc = new XmlDocument(); using( XmlReader reader = XmlReader.Create( xmlPath, settings ) ) { doc.Load( reader ); // <-- This line throws an exception if XML is ill-formed reader.Close(); } doc.Validate( SchemaValidationCallBack );// <-- This is never reached } private void SchemaValidationCallBack( object sender, ValidationEventArgs e ) { Console.WriteLine( "SchemaValidationCallBack: " + e.Message ); } How do I get the callback to be called so I can handle validation errors? Thanks for your help!

• Fixed div once page is scrolled is flickering

  - by jasondavis

  I am trying to have an advertisement block/div that will be hald way down the page, once you scroll do the page to this point it will stick to the top. Here is a demo of what I am trying to do and the code I am using to do it with... http://jsfiddle.net/jasondavis/6vpA7/3/embedded/result/ In the demo it works perfectly how I am wanting it to be, however when I implement it on my live site, http://goo.gl/zuaZx it works but when you scroll down the div flickers in and out of view on each scroll or down key press. On my site to see the problem live it is the blokc on the right sidebar that says "Recommended Books" Here is the code I am using... $(document).ready( function() { $(window).scroll( function() { if ($(window).scrollTop() > $('#social-container').offset().top) $('#social').addClass('floating'); else $('#social').removeClass('floating'); } ); } );? css #social.floating { position: fixed; top: 0; }? My demo jsfiddle where it works correctly http://jsfiddle.net/jasondavis/6vpA7/3/ The only thing different on my live site is the div/id name is different. As you can see it is somewhat working on my live site except the flickering in and out of view as you scroll down the page. Anyone have any ideas why this would happen on my live site and not on my jsfiddle demo?

• PreparedStatement question in Java against Oracle.

  - by fardon57

  Hi everyone, I'm working on the modification of some code to use preparedStatement instead of normal Statement, for security and performance reason. Our application is currently storing information into an embedded derby database, but we are going to move soon to Oracle. I've found two things that I need your help guys about Oracle and Prepared Statement : 1- I've found this document saying that Oracle doesn't handle bind parameters into IN clauses, so we cannot supply a query like : Select pokemon from pokemonTable where capacity in (?,?,?,?) Is that true ? Is there any workaround ? ... Why ? 2- We have some fields which are of type TIMESTAMP. So with our actual Statement, the query looks like this : Select raichu from pokemonTable where evolution = TO_TIMESTAMP('2500-12-31 00:00:00.000', 'YYYY-MM-DD HH24:MI:SS.FF') What should be done for a prepared Statement ? Should I put into the array of parameters : 2500-12-31 or TO_TIMESTAMP('2500-12-31 00:00:00.000', 'YYYY-MM-DD HH24:MI:SS.FF') ? Thanks for your help, I hope my questions are clear ! Regards,

• Hidden youtube player loses its methods

  - by zaius

  I'm controlling a embedded youtube chromeless player with javascript, and I want to hide it occasionally by setting display: none. However, when I show the player again, it loses its youtube methods. For example: <script> swfobject.embedSWF("http://www.youtube.com/apiplayer?enablejsapi=1&playerapiid=player", "player", "425", "356", "8", null, null, {allowScriptAccess: "always"}, {id: 'player'} ); var player = null; function onYouTubePlayerReady(playerId) { player = document.getElementById(playerId); player.addEventListener('onStateChange', 'playerStateChanged'); } function hidePlayer() { player.pauseVideo(); player.style.display = 'none'; } function showPlayer() { player.style.display = 'block'; player.playVideo(); } </script> <a href="#" onClick="hidePlayer();">hide</a> <a href="#" onClick="showPlayer();">show</a> <div id="player"></div> Calling hidePlayer followed by showPlayer gives this error on the playVideo call: Uncaught TypeError: Object #<an HTMLObjectElement> has no method 'playVideo' The only solution I can find is to use visibility: hidden, but that is messing with my page layout. Any other solutions out there?

  - by Jason

  I need to have a flash intro for my website (a requirement from my teacher). I created the intro and embedded it into my page. I takes up the entire screen in both Chrome and Chromium. In IE8, Firefox and Opera the size is incorrect. What am I doing wrong? <!DOCTYPE html> <html> <head> <meta http-equiv="Refresh" content="3; url=template.htm"> <meta charset="UTF-8"> <title>Com Tech Projects | Jason Cook</title> </head> <body style="background: black;"> <embed style="height: 100%; width: 100%;" src="Flash/Introv6.swf"/> </body> </html>

• Linux C debugging library to detect memory corruptions

  - by calandoa

  When working sometimes ago on an embedded system with a simple MMU, I used to program dynamically this MMU to detect memory corruptions. For instance, at some moment at runtime, the foo variable was overwritten with some unexpected data (probably by a dangling pointer or whatever). So I added the additional debugging code : at init, the memory used by foo was indicated as a forbidden region to the MMU; each time foo was accessed on purpose, access to the region was allowed just before then forbidden just after; a MMU irq handler was added to dump the master and the address responsible of the violation. This was actually some kind of watchpoint, but directly self-handled by the code itself. Now, I would like to reuse the same trick, but on a x86 platform. The problem is that I am very far from understanding how is working the MMU on this platform, and how it is used by Linux, but I wonder if any library/tool/system call already exist to deal with this problem. Note that I am aware that various tools exist like Valgrind or GDB to manage memory problems, but as far as I know, none of these tools car be dynamically reconfigured by the debugged code. I am mainly interested for user space under Linux, but any info on kernel mode or under Windows is also welcome!
