  • Using sed to convert hex characters in postgresql dump file

    - by Bernt
    I am working on moving several databases from a Postgresql 8.3 server to a Postgresql 8.4 server. It has worked fine so far, but one base has given me some trouble. The database is listed as unicode-encoded in the 8.3-server, but somehow a client program has managed to inject some invalid unicode data into it. When I do a normal dump and restore using postgres' custom format, the new server won't accept it, complaining about unicode errors. My plan is to do a plain text dump of the database, then use sed to replace the invalid characters with nothing (they are not needed). But how do you make sed work on hex/binary values in a file?

  • [Linux] Bind/map Character to alt+[some key]?

    - by Paul
    OS: Ubuntu In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+æ (Norwegian letter) to '{' system wide? Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms... :)

  • When I type certain characters, they come out as backquotes

    - by JXG
    Very strange behavior. Some background: I bought a new lenovo G550 laptop, running Windows 7. I live in Israel. When I type certain keys, in any application, they are prefaced with the backquote (`). These characters are: Insert, Delete, Left Ctrl (the right-hand one is fine), - (the regular dash: the one on the keypad is fine), =, 5 (the regular one), 4 (the one on the numeric keypad, whether or not Num Lock is on), and PgDn (the regular one). When I press the Fn key with these I don't get the behavior. Does anyone know why this is happening, or how I can fix it?

  • PuTTY inserts random characters during a session

    - by Zachary Polikarpus
    I recently started renting space on a remote server so that I could work on a project. I found that a relatively painless way to access it on a windows machine is through PuTTY. However, there is one thing that has always irked me when using it: for seemingly no reason random characters are sometimes inserted at the cursor. Most of the time it is just a single tilde, but rarely it spits out what looks like some escape sequence ([[^8 or the like). It will only occur when I am focused on the window, whether I am typing or 20 feet away from the keyboard. If left for long enough, it will spit tildes at random intervals (average is about 1 minute). Finally, this behavior seems to be inconsistant when running programs such as nano or the mysql interface: in nano, instead of inserting tildes, it will set marks (ctrl-^); in mysql, lines will become un-editable. My question is this: Has anyone else experienced this sort of behavior in PuTTY? And if so, what can be done to prevent/correct this behavior?

  • Incremental search for un/accented characters

    - by user38983
    Does emacs have an incremental search mode, where searching for a character will search for itself and for any other versions of the character with accent marks, similar to how Google Chrome (at least v27) will do when searching in a page? Alternatively, is there an additional library or piece of elisp code that can put incremental search in such a mode? For example, incremental search for: 'manana', would find 'manana' or 'mañana' 'motley crue', would also find 'Mötley Crüe' (with case-sensitivity off). Even a solution that only covers a subset of these characters would be helpful.

  • php returns junk characters at end of everything

    - by blindJesse
    php appears to be adding junk characters to the end of everything it returns on a friend's site. I'm not an admin on the server but I'd like to give an informed complaint to get this fixed. The site is http://daytoncodebreakers.org. You can see some junk at the end of every page on the site (what appear to be question marks with something else in the middle). I originally thought this was a wordpress issue, but check out http://daytoncodebreakers.org/whereisini.php (which is just a call to phpinfo), and http://daytoncodebreakers.org/hello.php (which is just 'Hello World'). I'm not sure if this is the most appropriate site, but I think this is a server config issue, so I'm posting it here (rather than stackoverflow or superuser). Feel free to move it if want.

  • Excel, Lookup special characters and spaces.

    - by Sisyphus
    I have an excel, spreadsheet that has multiple sheets. The first sheet is an index of files, I am using the following forumla to look up a value in column A, references against the index sheet, if it matches then it copies the value from column B from the index sheet. The forumla is: =IF($A3="", "", (LOOKUP($A3, INDEX!$A$3:$A$26, INEDEX!B$3:B$26))) It works for data that has no spaces and special characters, anybody have any ideas why it doesn't work and how I can make it work? Thanks in advance.

  • dojo.require() prevents Firefox from rendering the page

    - by Eduard Wirch
    Im experiencing strange behavior with Firefox and Dojo. I have a html page with these lines in the <head> section: ... <script type="text/javascript" src="dojo.js" djconfig="parseOnLoad: true, locale: 'de'"></script> <script type="text/javascript"> dojo.require("dojo.number"); </script> ... Sometimes the page loads normally. But sometimes it won't. Firefox will fetch the whole html page but not render it. I see only a gray window. After some experiments I figured out that the rendering problem has something to do with the load time of the html. Firefox starts evaluating the html page while loading it. If the page takes too long to load the above javascript will be executed BEFORE the html finishes loading. If this happens I'll get the gray window. Advising Firefox to show me the source code of the page will display the correct complete html code. BUT: if I save the page to disk (File-Save Page As...) the html code will be truncated and the above part will look like this: ... <script type="text/javascript" src="dojo.js" djconfig="parseOnLoad: true, locale: 'de'"></script> <script type="text/javascript"> dojo.require("dojo.number"); </script></head><body></body></html> This explains why I get to see a gray area. But why does this code appear there? I assume the require() method of Dojo does something "evil". But I can't figure out what. There is no write.document("</head><body></body></html>"); in the Dojo code. I checked for it. The problem would be fixed, if I'd place the dojo.require("dojo.number"); statement in the window.load event: <script type="text/javascript"> window.load=function() { dojo.require("dojo.number"); } </script> But I'm curious why this happens. Is there a Javasctript function which forces Firefox to stop evaluating the page? Does Dojo do somethig "bad"? Can anyone explain this behavior to me? EDIT: Dojo 1.3.1, no JS errors or warnings.

  • Rails escape_javascript creates invalid JSON by escaping single quotes

    - by Arrel
    The escape_javascript method in ActionView escapes the apostrophe ' as backslash apostrophe \', which gives errors when parsing as JSON. For example, the message "I'm here" is valid JSON when printed as: {"message": "I'm here"} But, <%= escape_javascript("I'm here") %> outputs "I\'m here", resulting in invalid JSON: {"message": "I\'m here"} Is there a patch to fix this, or an alternate way to escape strings when printing to JSON?

  • Backslashes in gsub (escaping and backreferencing)

    - by polygenelubricants
    Consider the following snippet: puts 'hello'.gsub(/.+/, '\0 \\0 \\\0 \\\\0') This prints (as seen on ideone.com): hello hello \0 \0 This was very surprising, because I'd expect to see something like this instead: hello \0 \hello \\0 My argument is that \ is an escape character, so you write \\ to get a literal backslash, thus \\0 is a literal backslash \ followed by 0, etc. Obviously this is not how gsub is interpreting it, so can someone explain what's going on? And what do I have to do to get the replacement I want above?

  • Having an @ inside of a string - PHP

    - by Msencenb
    So I know that you use a backslash to escape most things in php however the @ symbol is an operator that suppresses error messages. I'm trying to put an email string like this inside of an array "[email protected]", however php is throwing an error. How do you escape the @ sign? EDIT: Here is the code example that was throwing the error: $arr = array(3=> "[email protected]",4=> "[email protected]"); However replacing the double quotes with single quotes fixes the error as answered below.... why is that true?

  • color letters in a div

    - by Growler
    I've created a palindrome checker. I want to take it one step further and show the letters being compared as it is being checked. HTML: <p id="typing"></p> <input type="text" id="textBox" onkeyup="pal(this.value);" value="" /> <div id="response"></div> <hr> <div id="palindromeRun"></div> JS: To do this, I run the recursive check... Then if it is a palindrome, I run colorLetters(), which I'm trying to highlight in green each letter as it is being checked. Right now it is just rewriting palindromeRun's HTML with the first letter. I know this is because of the way I'm resetting its HTML. I don't know how to just grab the first and last letter, change only those letters' css, then increment i and j on the next setTimeout loop. var timeout2 = null; function pal (input) { var str = input.replace(/\s/g, ''); var str2 = str.replace(/\W/, ''); if (checkPal(str2, 0, str2.length-1)) { $("#textBox").css({"color" : "green"}); $("#response").html(input + " is a palindrome"); $("#palindromeRun").html(input); colorLetters(str2, 0, str2.length-1); } else { $("#textBox").css({"color" : "red"}); $("#response").html(input + " is not a palindrome"); } if (input.length <= 0) { $("#response").html(""); $("#textBox").css({"color" : "black"}); } } function checkPal (input, i, j) { if (input.length <= 1) { return false; } if (i === j || ((j-i) == 1 && input.charAt(i) === input.charAt(j))) { return true; } else { if (input.charAt(i).toLowerCase() === input.charAt(j).toLowerCase()) { return checkPal(input, ++i, --j); } else { return false; } } } function colorLetters(myinput, i, j) { if (timeout2 == null) { timeout2 = setTimeout(function () { console.log("called"); var firstLetter = $("#palindromeRun").html(myinput.charAt(i)) var secondLetter = $("#palindromeRun").html(myinput.charAt(j)) $(firstLetter).css({"color" : "red"}); $(secondLetter).css({"color" : "green"}); i++; j++; timeout2=null; }, 1000); } } Secondary: If possible, I'd just like to have it colors the letters as the user is typing... I realize this will require a setTimeout on each keyup, but also am not sure how to write this.

  • How can I save shell output to a variable in LaTeX?

    - by Frank
    I need to be able to execute a shell command through LaTeX [*] and have the resulting output available for use later on in the form of a LaTeX 'variable' (e.g., via a subsequent \newcommand command). If necessary a temporary file could be used to hold the output, although I would like to avoid this. I have been able to use \immediate\write18 to invoke a bash command before, but this was only used to write to a temporary file. [*] I realise that the -shell-escape flag must be set for this to be allowed

  • style a navigation link when a particular div is shown

    - by Matt Meadows
    I have JQuery working to show a particular div when a certain link is clicked. I have managed to apply the effect I'm after with the main navigation bar through id'ing the body tag and using css to style when the id is found. However, i'd like to apply the same effect to the sub navigation when a certain div is present. How the main navigation is styled: HTML: <nav> <ul> <li id="nav-home"><a href="index.html">Home</a></li> <li id="nav-showreel"><a href="showreel.html">Showreel</a></li> <li id="nav-portfolio"><a href="portfolio.html">Portfolio</a></li> <li>Contact</li> </ul> </nav> CSS: body#home li#nav-home, body#portfolio li#nav-portfolio { background: url("Images/Nav_Underline.png") no-repeat; background-position: center bottom; color: white; } (Other links havent been added to styling as those pages are still in development) How the sub navigation is structured: <nav id="portfolioNav"> <ul> <li id="portfolio-compositing"><a id="compositingWork" href="#">Compositing</a></li> <li id="portfolio-animation"><a id="animationWork" href="#">Animation</a></li> <li id="portfolio-motionGfx"><a id="GFXWork" href="#">Motion Graphics</a></li> <li id="portfolio-3D"><a id="3DWork" href="#">3D</a></li> </ul> </nav> As you can see, its similar format to the main navigation, however i've tried the same approach and it doesn't work :( The Javascript that switches the divs on the navigation click: <script type="text/javascript"> $(document).ready(function() { $('#3DWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #Portfolio3D'); }); $('#GFXWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #motionGraphics'); }); $('#compositingWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioCompositing'); }); $('#animationWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioAnimation'); }); }); </script> JSFiddle for full HTML & CSS : JSFiddle File The effect I'm After:

  • Why are you doing this? [closed]

    - by NIcholas Lawson
    I am working on a story that I am going to be querying to several magazines in my hometown about this work that is being done by the AXR group. This is a group of people who have networked online and are working on developing a higher level syntax structure than CSS and HTML currently offer. I am covering this is as a story because I see potential in this as a human interest story in cosmopolitan society. I have been asked by the group to pose this question to you and would appreciate any and all comments you would have on the following ... To AXR: So when does the internet become finished? At what point does a computer scientist say to himself ... my job here is finished ... the internet is complete? When is the internet ready to be more about the display of content than the uploading of new websites or computer tech? You are embarking on upon a sixty year project every day you work with this internet, what drives you? Why are you spending your hard earned hours working on the code to this computer? I spend thirty hours a week online because I love the writing and I know what would make the internet better ... ease of use ... i know it is difficult to program but I see some very elegant solutions online ... in this early inception phase of your programming development for this HSS prototype ... I would like to know why I do not see you programmers asking questions such as ... What would make the end user's life the easiest when using this code? I know you can solve the problem but an evolution forward would be simple, not simple to a computer scientist but simple to use for a career janitor ... if you could solve the problem of alleviating the stress at using a the computer you could get better content out of the computer ... right now the main problem is that the best content is in the hands of the people least likely to use the computer and the more simple you make the computer to use ... the better the content collection will be in the long run ... That is not what I want to talk about though ... why are you writing code when you could be writing stories? I know the computer is worthless without content so I build content, I know the book is worthless without the combinations of words in them, i know the television is worthless without the television news anchor or the actor, what I want to know from you folks in a very journalistic sense is why are you even bothering to bother to write code for a machine that has only made our lives i would dare say less interesting. why are you feeding the beast your time when you could be writing stories or being an actor or musician or auto mechanic ... why code? why this machine? what do you love about it? what do you hate about it? what do you wonder about it? I want to know so that starting out I know how to further shape my questions with axr ... i want the full story ... i want the real answers ... and i want to know why you are doing this, it would make for great writing if you could elucidate on this point.

  • New HTML 5 input types in ASP.Net 4.5 Developer Preview

    - by sreejukg
    Microsoft has released developer previews for Visual Studio 2011 and .Net framework 4.5. There are lots of new features available in the developer preview. One of the most interested things for web developers is the support introduced for new HTML 5 form controls. The following are the list of new controls available in HTML 5 email url number range Date pickers (date, month, week, time, datetime, datetime-local) search color Describing the functionality for these controls is not in the scope of this article. If you want to know about these controls, refer the below URLs http://msdn.microsoft.com/en-us/magazine/hh547102.aspx http://www.w3schools.com/html5/html5_form_input_types.asp ASP.Net 4.5 introduced more possible values to the Text Mode attribute to cater the above requirements. Let us evaluate these. I have created a project in Visual Studio 2011 developer preview, and created a page named “controls.aspx”. In the page I placed on Text box control from the toolbox Now select the control and go to the properties pane, look at the TextMode attribute. Now you can see more options are added here than prior versions of ASP.Net. I just selected Email as TextMode. I added one button to submit my page. The screen shot of the page in Visual Studio 2011 designer is as follows See the corresponding markup <form id="form1" runat="server">     <div>         Enter your email:         <asp:TextBox ID="TextBox1" runat="server" TextMode="Email"></asp:TextBox     </div>     <asp:Button ID="Button1" runat="server" Text="Submit" /> </form> Now let me run this page, IE 9 do not have the support for new form fields. I browsed the page using Firefox and the page appears as below. From the source of the rendered page, I saw the below markup for my email textbox <input name="TextBox1" type="email" id="TextBox1" /> Try to enter an invalid email and you will see the browser will ask you to enter a valid one by default. When rendered in non-supported browsers, these fields are behaving just as normal text boxes. So make sure you are using validation controls with these fields. See the browser support compatability matrix with these controls with various browser vendors. ASP.Net 4.5 introduced the support for these new form controls. You can build interactive forms using the newly added controls, keeping in mind that you need to validate the data for non-supported browsers.

  • View HTML Tags and Webpage Combined in Firefox

    - by Asian Angel
    Do you want an easier way to see a webpage’s html tags without viewing the source code in a separate window? Now you can view the webpage and tags combined in the same window using the X-Ray extension for Firefox. Before Usually if you want to see the source code behind a webpage you have to view it in a separate window. If you are only interested in a specific section then you have to search through the entire set of code just to find what you are looking for. After The X-Ray extension will let you see the document’s tags (including class and ID names) “side by side” with the webpage in the same tab. You can use either the context menu or the tools menu to access the X-Ray command. Here is the same webpage section shown in the first screenshot above. It may look a little odd at first until you get used to seeing both together. Note: You can return the webpage to its’ normal view by either clicking on the X-Ray command again or refreshing the page. The code for part of the sidebar on the same webpage… Followed by one of the sets of links at the end. Looking at another example suppose you are interested in how part of the main feed is set up. Being able to see how a particular element is set up directly in the webpage is certainly better than searching through the entire page of code. Conclusion If you design webpages and want an easy way to see how someone else’s website is coded then you may want to give this extension a try.
