  • Using large transparent pictures as texture atlases

    - by azlisum
    i'm new to android programming and i'm trying to create a relatively big 2D game. I have to use lots of images and objects in my game so I decided to use OpenGL ES. I have several texture atlases, all of them saved as png's because of the transparency. I also know, but i'm not sure why, that I have to use images, which height and width is multiple of two. I test my game on an old HTC Hero running Android 2.3.3. When my picture atlases are 512x512 each, my game has a frame rate of between 50 to 60 fps. When I use 1024x1024 non transparent png, there is no problem - the FPS is again between 50 to 60 fps. But when i decide to use a 1024x1024 transperent PNG's my frame rate drops to 4,5 fps. Could this be a problem related to the age of the device i'm using for testing? These are the OpenGL functions I use each loop to draw batches: gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); //drawing happens here gl.glDisable(GL10.GL_BLEND); Thanks in advance :)

  • MySQL TEXT field performance

    - by Jonathon
    I have several TEXT and/or MEDIUMTEXT fields in each of our 1000 MySQL tables. I now know that TEXT fields are written to disk rather than in memory when queried. Is that also true even if that field is not called in the query? For example, if I have a table (tbExam) with 2 fields (id int(11) and comment text) and I run SELECT id FROM tbExam, does MySQL still have to write that to disk before returning results or will it run that query in memory? I am trying to figure out if I need to reconfigure our actual db tables to switch to varchar(xxxx) or keep the text fields and reconfigure the queries.

  • How to find text in images with the browser control+F

    - by Riga
    Have HTML pages with many sections and each section has a section title displayed as an image (to use nice font). The problem is that even if I specify an 'alt' and 'title' text on each image/title the Ctrl+F browser functionality does not find the text. Thought two possible solutions but not very happy about them 1) Use embed fonts. Problem: Can not find the font required by client to use and not sure about copyrights. 2) Have the text in the image in DIV near the image but hidden from user view. Problem: Can search engines consider this keyword stuffing? Will browser find text if display:none Does anybody has a better solution? Thanks Riga

    Hello, this is actually an problem question from project euler site http://projecteuler.net/index.php?section=problems&id=3 Anyway I'm not out after the solution, but I probably guess you will know what my approach is. To my question now, how do I handle numbers exceeding unsigned int? Is there a mathematical approach for this, if so where can I read about it?

  • Background text in a Bootstrap WELL

    - by patrick
    I have a problem putting a text in the background of a Bootstrap well. I first posted the problem in this question, but that was a too simple representation of my problem. I'm looking for an effect created in this jFiddle, a text in the background of a menu. The example works how I want to to work, but when I put this in a Bootstrap Well I get this (http://jsfiddle.net/aBqw8/21/). The background text disappears, it's probably behind the Well. When I remove the background color from the well I can see the text. If I remove the "position:relative" from the span it shows the title, but then it interferes with the menu, which is what I am trying to avoid. Thanks for your help!

  • Handling large numbers of sockets with .NET

    - by Dreaddan
    I'm looking at writing a application that need to be able to handle in the region of 200 connections / sec and was wondering if C# and .NET will handle this or if I need to really be looking at C++ to do this? It looks like SocketAsyncEventArgs may be the way to go but thought id check before I plough in to it. Each transaction should only last less than a second but could take up to 15 seconds each if that makes any difference.

  • Dealing with large directories in a checkout

    - by Eric
    I am trying to come up with a version control process for a web app that I work on. Currently, my major stumbling blocks are two directories that are huge (both over 4GB). Only a few people need to work on things within the huge directories; most people don't even need to see what's in them. Our directory structure looks something like: / --file.aspx --anotherFile.aspx --/coolThings ----coolThing.aspx --/bigFolder ----someHugeMovie.mov ----someHugeSound.mp3 --/anotherBigFolder ----... I'm sure you get the picture. It's hard to justify a checkout that has to pull down 8GB of data that's likely useless to a developer. I know, it's only once, but even once could be really frustrating for someone (and will make it harder for me to convince everyone to use source control). (Plus, clean checkouts will be painfully slow.) These folders do have to be available in the web application. What can I do? I've thought about separate repositories for the big folders. That way, you only download if you need it; but then how do I manage checking these out onto our development server? I've also thought about not trying to version control those folders: just update them directly on the web server... but I am not enamored of this idea. Is there some magic way to simply exclude directories from a checkout that I haven't found? (Pretty sure there is not.) Of course, there's always the option to just give up, bite the bullet, and accept downloading 8 useless GB. What say you? Have you encountered this problem before? How did you solve it?

  • C# chart control Performance with large amounts of data

    - by user3642115
    I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series. The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down. Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues. Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens. Thanks.

  • Partially fattening a list

    - by alj
    This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples? (I've looked at the itertools but it flattens everything) What I currently get is: ('id', 20, 'integer') ('companyname', 50, 'text') [('focus', 30, 'text'), ('fiesta', 30, 'text'), ('mondeo', 30, 'text'), ('puma', 30, 'text')] ('contact', 50, 'text') ('email', 50, 'text') what I would like is a single level list like: ('id', 20, 'integer') ('companyname', 50, 'text') ('focus', 30, 'text') ('fiesta', 30, 'text') ('mondeo', 30, 'text') ('puma', 30, 'text') ('contact', 50, 'text') ('email', 50, 'text') def getproducts(): temp_list=[] product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db for p in product_list: temp_list.append((p,30,'text')) return temp_list def createlist(): column_title_list = ( ("id",20,"integer"), ("companyname",50,"text"), getproducts(), ("contact",50,"text"), ("email",50,"text"), ) return column_title_list for item in createlist(): print item Thanks ALJ

  • How to change a label's text after loading a html into a dialog

    - by Salsa
    I am opening a modal dialog by loading a form into it. After loading the form, I want to change it's title and one of it's fields' label. I can change the label's text, but after the function returns, the label's text turns back to it's original one. Is it possible to make this kind of change and if so, how? The HTML: <form action="testing.php" method="POST" id="example-form"> <fieldset> <label for="link" id="link-label"></label> </fieldset> </form> The javascript: $(".bt-example").button().click(function() { $('#example-dialog').load('form.html').dialog('open'); $('.ui-dialog-titlebar').text("THIS WORKS!"); $('#example-form #link-label').text("CHANGES AT FIRST, BUT GOES BLANK LATER"); $('#example-dialog').removeClass('invisible'); });

  • Large Data Table with first column fixed

    - by bhavya_w
    I have structure as shown in the fiddle http://jsfiddle.net/5LN7U/. <section class="container"> <section class="field"> <ul> <li> Question 1 </li> <li> question 2 </li> <li> question 3 </li> <li> question 4 </li> <li> question 5 </li> <li> question 6 </li> <li> question 7 </li> </ul> </section> <section class="datawrap"> <section class="datawrapinner"> <ul> <li><b>Answer 1 :</b></li> <li><b>Answer 2 :</b></li> <li><b>Answer 3 :</b></li> <li><b>Answer 4 :</b></li> <li><b>Answer 5 :</b></li> <li><b>Answer 6 :</b></li> <li><b>Answer 7 :</b></li> </ul> </section> </section> </section> Basically its a table structure made using divs. The first column contains a long list of questions and the second column contains answers/multiple answers which can be quite big ( there has to be horizontal scrolling in the second column.) The problem i am facing is when i scroll downwards the second column which has the horizontal scroll bar is also scrolling downward. I want horizontal scrollbar to be fixed there. as in it should be always fixed there no matter how much i scroll vertically. Much Like Google Spreadsheets: where the first column stays fixed and there's horizontal scrolling on rest of the columns with over vertical scrolling for whole of the data. I cannot used position fixed in the second column. P.S : please no lectures on using div's for making a table structure. I have my own reasons. and its kinda urgent. Thanks in advance.

  • How to define large list of strings in Visual Basic

    - by Jenny_Winters
    I'm writing a macro in Visual Basic for PowerPoint 2010. I'd like to initialize a really big list of strings like: big_ol_array = Array( _ "string1", _ "string2", _ "string3", _ "string4" , _ ..... "string9999" _ ) ...but I get the "Too many line continuations" error in the editor. When I try to just initialize the big array with no line breaks, the VB editor can't handle such a long line (1000+) characters. Does anyone know a good way to initialize a huge list of strings in VB? Thanks in advance!

  • Apache returns 304, I want it to ignore anything from client and send the page

    - by Ayman
    I am using Apache HTTPD 2.2 on Windows. mod_expires is commented out. Most other stuff are not changed from the defaults. gzip is on. I made some changes to my .js files. My client gets one 304 response for one of the .js files and never gets the rest. How can I force Apache to sort of flush everything and send all new files to the client?

  • Is it possible to make CSS-added text searchable by a browser?

    - by Andrew Stacey
    I run a website that uses CSS pseudo classes to insert text here and there. One of them inserts the value of a CSS counter (whereupon it would require considerable re-engineering of the system to do this without CSS text injection). The specific CSS rule is: .num_defn .theorem_label:after { content: " " counter(definition, decimal); counter-increment: definition; } and this converts "Definition" to "Definition 1" (say). However, the injected text is not searchable by the browser. It doesn't see the 1: if I search for "Definition 1" then it doesn't find it, and if I search for "Definition. Whatever the definition text was" then the browser happily highlights the line except for the inserted 1. So if you imagine the bold text as the highlighting, it would look like: Definition 1 . Whatever the definition text was This is not ideal! People like to refer to definitions by their number and to say "Look at Definition 1 on the page XYZ" (and in contexts where hyperlinks are not available - strange, I know, but it does happen). Thus: Is there any way that I, on the server end, can designate the injected text as "searchable"? If not, is there a simple way at the browser end that this can be enabled?

  • Any good reason to open files in text mode?

    - by Tinctorius
    (Almost-)POSIX-compliant operating systems and Windows are known to distinguish between 'binary mode' and 'text mode' file I/O. While the former mode doesn't transform any data between the actual file or stream and the application, the latter 'translates' the contents to some standard format in a platform-specific manner: line endings are transparently translated to '\n' in C, and some platforms (CP/M, DOS and Windows) cut off a file when a byte with value 0x1A is found. These transformations seem a little useless to me. People share files between computers with different operating systems. Text mode would cause some data to be handled differently across some platforms, so when this matters, one would probably use binary mode instead. As an example: while Windows uses the sequence CR LF to end a line in text mode, UNIX text mode will not treat CR as part of the line ending sequence. Applications would have to filter that noise themselves. Older Mac versions only use CR in text mode as line endings, so neither UNIX nor Windows would understand its files. If this matters, a portable application would probably implement the parsing by itself instead of using text mode. Implementing newline interpretation in the parser might also remove some overhead of using text mode, as buffers would need to be rewritten (and possibly resized) before returning to the application, while this may be less efficient than when it would happen in the application instead. So, my question is: is there any good reason to still rely on the host OS to translate line endings and file truncation?

  • Apache sends plain-text response when accessing SSL-enabled site without HTTPS

    - by animuson
    I've never encountered something such as this before. I was attempting to simply redirect the page to the HTTPS version if it determined that HTTPS was off, but instead it's displaying an HTML page rather than actually redirecting; and even odder, it's displaying it as text/plain! The VirtualHost Declaration (Sort of): ServerAdmin [email protected] DocumentRoot "/path/to/files" ServerName example.com SSLEngine On SSLCertificateFile /etc/ssh/certify/example.com.crt SSLCertificateKeyFile /etc/ssh/certify/example.com.key SSLCertificateChainFile /etc/ssh/certify/sub.class1.server.ca.pem <Directory "/path/to/files/"> AllowOverride All Options +FollowSymLinks DirectoryIndex index.php Order allow,deny Allow from all </Directory> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule .* https://example.com:6161 [R=301] The Page Output: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I've tried moving the Rewrite stuff up above the SSL stuff hoping it'd do something and nothing happens. If I view the page with via HTTPS, it displays fine like it should. It's obviously detecting that I'm trying to rewrite the path, but it's not acting. The Apache error log does not indicate anything to me that might have gone wrong. When I remove the RewriteRules: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://example.com/"><b>https://example.com/</b></a></blockquote></p> <p>Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I get the standard "you can't do this because you're not using SSL" response, which is also provided in text/plain rather than being rendered as HTML. This would make sense, it should only work for HTTPS-enabled connections, but I still want to redirect them to the HTTPS connection when it determines that it is not enabled. Thinking I could circumvent the system: I tried adding a ErrorDocument 400 https://example.com:6161 to the config file instead of using RewriteRules, and that just gave me a new message, still no cheese. <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>302 Found</title> </head><body> <h1>Found</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> How can I force Apache to actually redirect rather than displaying a "301" page that shows HTML in plain-text format?

  • Windows 7 search doesn’t find text strings

    - by Hugh Tash
    I’m not able to find any text strings starting not from the beginning of word in filename or in file content using Windows 7 search. My Windows 7 search configuration: Let’s say I’m searching for a documents containing word “content”. I’m able to find those documents when searching for “content”, “conte”, “con” (as long as the string includes the beginning of the word). "content" "con" But if I search for “ontent”, “tent” or any other combination that doesn’t include the beginning of the word, Windows search won't find it. I've tried other indexing/searching software such as Copernic Desktop search, Google desktop search. Those programs also weren’t able to find part of the word starting from the middle of the word. For instance, it finds “conte”, but doesn’t find “onte”. Finds “conte” Doesn’t find “onte” I got the same problem using Copernic desktop search. On the other hand, when I use non-indexing content search software such as Agent Ransack or FileSeek, I get the same results when searching for “conte” or “onte”: “conte” “onte” Why do all pre-indexing content search applications (Windows search, Google desktop, Copernic desktop search) fail to search for a string inside the words? Why do non-indexing applications find text strings wherever they are: in the beginning, middle or end of the word? I’ve tried wildcards and other constructions with no luck. *onte onte “onte” content:onte content:onte content:~onte All these searched doesn’t find the word “content”. How can I make Windows search find strings from any part of words? Could you try these searches and see if they work for you? Or is this normal behavior? Thank you. Update: Using wildcards before or after "onte" doesn't find any results. content:~=onte doesn't find any results.

  • Switch Text Paragraphs in OpenOfficeOrg Writer mailmerge

    - by Glen S. Dalton
    I am using mailmerge to write the same letter with minor differenes to many peolpe. I experienced that switching text paragraphs depending on database values was not easy for me. I ended up putting huge text paragraphs into the database becaus switching did not really work for me. Actually I dont' understand how writer does it and maybe the boolean evaluation is buggy? There is some possibility making paragraphs invisible depending on database fields, but it was frustrating. After marking a paragraph as invisible (depending on a condition) it went invisible in the main document and did not come back, I lost the content. An example in pseudocode of what I want in my mailmerge document: {if [[balance]] 10} We owe you money. Please can you send your bank details. {end if} {if [[balance]] < -10} Please transfer the remaining amount to our banc account 123... {end if} Maybe this could be done with makros? But how to combine makros with mailmerge? Can you tell me what are the pitfalls and how to master them? I once did this with ms word, it was a lot easier. The normal mailmerge (including database fields in the letters) works fine for me in OpenOffice writer.

  • Textmate add multiline text at end of line

    - by Yuval
    In Textmate, I am able to add text to several lines at once by clicking and holding the Option key and dragging with the mouse. say I have the following lines: foo 1: foo 2: foo 3: I can easily click and hold option and then drag down with the lines to select the text at the end of each line, and then type "bar" once and it will be added to all lines, as such: foo 1: bar foo 2: bar foo 3: bar Fantastic. The problem I run into, is when my lines aren't the same length, as such foo 19: foo 37842342346: foo 503: Now if I want to add text to the end of each line, I have to either do it manually, or choose enough space so that the longest line is not overwritten, as such: foo 19: bar foo 37842342346: bar foo 503: bar This results in a lot of unwanted whitespace in lines that don't need it. Granted, I could easily run a regular expression search to replace all multiple occurrences of a space with a single one, but I was wondering if there's a way to select all ending of lines at once without having to do that. Any idea? Thanks!
