  • Formula needed: Sort Array

    - by aw
    I have the following array: a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] I use it for some visual stuff like this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Now I want to sort the array like this: 1 3 6 10 2 5 9 13 4 8 12 15 7 11 14 16 //So the original array should look like this: a = [1,5,2,9,6,3,13,10,7,4,14,11,8,15,12,16] Yeah, now I'm looking for a smart formula to do that ticker = 0; originalArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] newArray = []; while(ticker < originalArray.length) { //do the magic here ticker++; }

  • Message Date/Time tag in Lotus Notes

    - by TeeKay
    I've noticed that within Notes (8.5.2, basic client, fat client and iNotes) the date/time displayed on the eMail envelope AND the date/time on the message header is the same and appearently that time that Domino received the message. When using BES, the message forwarded to the BlackBerry by Domino/BES has the RECEIVED date/time on the envelope and the SENT date/time displayed in the message. In the basic/fat client with properties the sent time is viewable in one of the "Received" tags. Having the sent time easily viewable is helpful, especially if your trying to trouble-shoot a problem. Is this a configuration feature? Is it selectable in the client or in Domino? Thx

  • Repeatedly querying xml using python

    - by Jack
    I have some xml documents I need to run queries on. I've created some python scripts (using ElementTree) to do this, since I'm vaguely familiar with using it. The way it works is I run the scripts several times with different arguments, depending on what I want to find out. These files can be relatively large (10MB+) and so it takes rather a long time to parse them. On my system, just running: tree = ElementTree.parse(document) takes around 30 seconds, with a subsequent findall query only adding around a second to that. Seeing as the way I'm doing this requires me to repeatedly parse the file, I was wondering if there was some sort of caching mechanism I can use so that the ElementTree.parse computation can be reduced on subsequent queries. I realise the smart thing to do here may be to try and batch as many queries as possible together in the python script, but I was hoping there might be another way. Thanks.

  • Vendor neutral SQL

    - by Sparafusile
    I'm currently working on a project for a web application that may be installed on several different servers with various software configurations. I want to make my application as flexible as possible by allowing the user to have various SQL servers installed. The problem is the SQL syntax used by any two server vendors does not match up. For a simple example, here is the same SELECT statement for MS SQL and MySQL: MS SQL - SELECT TOP 1 * FROM MyTable ORDER BY DateCreated DESC MySQL - SELECT * FROM MyTable ORDER BY DateCreated DESC LIMIT 1 Are there any standard way to abstract the statement creation for various vendors? Any online resources or books discussing this problem? Any hints or smart-alec remarks that I'd find useful? Further information: I'm writing my we application in vanilla ASP running on a Windows server. Thanks, Spara

  • Compiler error when casting to function pointer

    - by detly
    I'm writing a bootloader for the PIC32MX, using HiTech's PICC32 compiler (similar to C90). At some point I need to jump to the real main routine, so somewhere in the bootloader I have void (*user_main) (void); user_main = (void (*) (void)) 0x9D003000; user_main(); (Note that in the actual code, the function signature is typedef'd and the address is a macro.) I would rather calculate that (virtual) address from the physical address, and have something like: void (*user_main) (void); user_main = (void (*) (void)) (0x1D003000 | 0x80000000); user_main(); ...but when I try that I get a compiler error: Error #474: ; 0: no psect specified for function variable/argument allocation Have I tripped over some vagarity of C syntax here? This error doesn't reference any particular line, but if I comment out the user_main() call, it goes away. (This might be the compiler removing a redundant code branch, but the HiTech PICC32 isn't particularly smart in Lite mode, so maybe not.)

  • Will there be IQueryable-like additions to IObservable? (.NET Rx)

    - by Jason
    The new IObservable/IObserver frameworks in the System.Reactive library coming in .NET 4.0 are very exciting (see this and this link). It may be too early to speculate, but will there also be a (for lack of a better term) IQueryable-like framework built for these new interfaces as well? One particular use case would be to assist in pre-processing events at the source, rather than in the chain of the receiving calls. For example, if you have a very 'chatty' event interface, using the Subscribe().Where(...) will receive all events through the pipeline and the client does the filtering. What I am wondering is if there will be something akin to IQueryableObservable, whereby these LINQ methods will be 'compiled' into some 'smart' Subscribe implementation in a source. I can imagine certain network server architectures that could use such a framework. Or how about an add-on to SQL Server (or any RDBMS for that matter) that would allow .NET code to receive new data notifications (triggers in code) and would need those notifications filtered server-side.

  • How to call a program and exit from the shell (the caller) when program is active?

    - by Jack
    I want to run a program with GUI, by typing into konsole: foo args … and exit from the shell (that's the caller) when the program (foo) is active. How do I this? Is there a Linux/Unix built-in command/program to do it? I'm not a shell-man, really. I know that it's possible by writing a small program in C or C++ (any other programming language with small I/O interface on POSIX) programming language with the fork() and one-of exec*() function family. It may take some time; I'll do it only if there is no native solution. Sorry for my bad English; it's not my native language. Also, not sure on tags, please edit for me, if I'm wrong. If it matters, I'm using OpenSUSE 10.x.

  • any suggestions on this css print problem

    - by user225269
    I have this code on my print.css: #header, #tae, #nav, .noprint {display: none;} width: 100%; margin: 0; float: none; In order not to display the elements within those div tags. But I don't know with the code below why it isn't cooperating. If I place the div tags on it. And then I hit the print button. I see no output. Here it is: <div id="tae"> <table border="0" align="center" cellpadding="0" cellspacing="0" class="bg1"> <tr> <td class="text1" style="height: 50px;">xd627 information management system</td> </tr> <tr> <td class="bg5"><table border="0" cellspacing="0" cellpadding="0" style="height: 62px; padding-top: 15px;"> <tr align="center"> <td><a href="userpage.php" class="link1">Homepage</a></td> <td><a href="RegStuds.php" class="link1">Database</a></td> <td><a href="#" class="link1">About</a></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> </table></td> </tr> <tr> <td valign="top" class="bg6">&nbsp;</td> </tr> <tr> <td><table width="780" border="0" cellspacing="0" cellpadding="0"> <tr valign="top"> <td width="20">&nbsp;</td> <td width="297"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td><img src="images/spacer.gif" alt="" width="30" height="30" /></td> </tr> </tr> <tr> <td class="text2"> </div> <div id="max"> <?php //some php code in here showing a mysql table. ?> </div> What's wrong with my code? Does the php script depend on the one where I put the div tag in? What do I do? All I want to show up in my page when printed is the mysql table. I'm using Universal Document Converter to simulate printing.

  • text options for seo-minded web developer

    - by benhowdle89
    I've been asked by a client if i could jazz up their tagline on their website i'm developing/designing. I've thought about the options and want to stay as SEO minded as i can but i'm struggling to think of a way i could strike a balance between having a really smart, anti-aliased looking heading at the top of their site under the logo but have it searchable/crawlable by the big G (google). Sifr? Cufon? Images? What do people recommend in terms of SEO and visual niceties?

  • Recommendation for Wiki that supports WYSIWYG?

    - by Kylotan
    Currently we use a MediaWiki installation for writing documentation, but several of us find the markup format horribly arbitrary and awkward, with a mixture of Wiki tags and XML in the text, and the lack of any quick formatting buttons for things like ordered or unordered lists, different heading levels, quick embedding of images, tables, code samples, etc. Sites like LiveJournal provide most or all of this while still generating backwards-compatible markup so it's not like there's a technological impediment here. There are other niceties that we'd like to see, such as being able to pick a category from a list (ala Wordpress) or maybe being able to apply syntax highlighting to code samples, etc. Do Wikis exist that provide a decent range of these features to make life easier on the editor? Something with the features and presentation of WordPress but the page organisation of a Wiki would be perfect. (WikiMatrix returns several candidates, but among them is MediaWiki, which quite clearly is not a WYSIWYG interface except in the most tenuous fashion. I'd rather not dig through each one if it's plain that WikiMatrix is not being entirely stringent about its criteria.)

  • Using Shell32 to extract Mimes on Windows Server 2008

    - by Léon Pelletier
    In a desktop app, I'm using Shell32 to extract Mime infos and ID3 tags. I want to do the same in ASP.Net on server side with http posted files, plus fetch some other infos, but as a Windows Server 2008, there are not several media applications installed, so I wonder if it will still retrieve a lot of informations from the files. Will it be possible to do it from server side? If yes, will it fetch several Mimes without media app installed. If not, is there some Mime pack to get some file informations without the app being installed. [EDIT] I installed VLC player and Windows Media Player on the server, which provide all MP3s / movies infos (Duration, Artist, Album, Width, Height, etc.), but I don't know if this is a good practice.

  • Best way to do something when a runloop event is done processing?

    - by quixoto
    I have some processing in my Cocoa app that sometimes ends up calling through a hierarchy of data to do a bunch of work as the result of an event. Each small piece creates and destroys some resources. I don't want those resources around most of the time, but I would like to find a smart way of creating them before all the work and killing them at the end. Short of creating the resources up front and then passing them entirely down through the call hierarchy when work is done, is there a way to know locally in some code when an event loop run has ended? Then I could create them if they're not there, and keep them until the run loop ends, reusing them for any subsequent calls before that time. Thanks.

  • C#: Efficiently search a large string for occurences of other strings

    - by Jon
    Hi, I'm using C# to continuously search for multiple string "keywords" within large strings, which are = 4kb. This code is constantly looping, and sleeps aren't cutting down CPU usage enough while maintaining a reasonable speed. The bog-down is the keyword matching method. I've found a few possibilities, and all of them give similar efficiency. 1) http://tomasp.net/articles/ahocorasick.aspx -I do not have enough keywords for this to be the most efficient algorithm. 2) Regex. Using an instance level, compiled regex. -Provides more functionality than I require, and not quite enough efficiency. 3) String.IndexOf. -I would need to do a "smart" version of this for it provide enough efficiency. Looping through each keyword and calling IndexOf doesn't cut it. Does anyone know of any algorithms or methods that I can use to attain my goal?

  • How can I change a specific website's style?

    - by Darthfett
    I have a specific website I often use (specifically, http://www.pygame.org/), which has an awful color scheme. I would like to change the color scheme of the site, but I haven't been able to find a good tool for the job. Some basic requirements: It should not be universal to all websites, or affect other websites. I want this to be semi-automatic. I don't want to have to re-define the theme for each page of the site. I want to continue to access the site online (I don't want a local copy of the entire site) Not OS-specific (browser-specific is okay) I am currently using Firefox, but I am also happy with Chrome. There may be some limitations on what is able to be done automatically, as the CSS seems to be embedded in the HTML (and some also in the HTML tags). I would like to remove as much of the green as possible. Is there an existing extension/add-on that does this?

  • Replicating iPhone Calendar View Lame?

    - by John Wright
    I am building an iPhone app that will need to display info primarily in a calendar view. Users will need to be able to search for entries and view them by day, month or in a list view. It seems like the built-in calendar type interface is ideal for my app. So I could build a similar calendar with 3 buttons at the bottom for list/day/month view as well as a button for today, in short a very similar interface to the built in iPhone calendar with different colors primarily. However, if I replicate it am I a) a lame copycat for replicating the built-in interface or smart for using a well-known iPhone metaphor and b) in danger of having my app rejected?

  • Displaying unnecessary HTML when showing content from MySQL database.

    - by ThatMacLad
    My homepage pulls in content from my MySQL database to create a blog. I've got it so that it only displays an extract from the posts. For some reason it displays HTML tags as well rather than formatting it using the tags (See picture below). Any help is appreciated.

  • How secure are GUIDs in terms of predictability?

    - by ssg
    We're using .NET's Guid.NewGuid() to generate activation codes and API keys currently. I wonder if that poses a security problem since their algorithm is open. .NET Guid uses Win32 CoCreateGuid and I don't know it's internals (possibly MAC address + timestamp?). Can someone derive a second GUID out of the first one, or can he hit it with some smart guesses or is the randomness good enough so search space becomes too big? Generating random keys have the problem of collision, they need a double check before adding to a database. That's why we stuck with GUIDs but I'm unsure about their security for these purposes. Here are the 4 consecutive UUIDGEN outputs: c44dc549-5d92-4330-b451-b29a87848993 d56d4c8d-bfba-4b95-8332-e86d7f204c1c 63cdf958-9d5a-4b63-ae65-74e4237888ea 6fd09369-0fbd-456d-9c06-27fef4c8eca5 Here are 4 of them by Guid.NewGuid(): 0652b193-64c6-4c5e-ad06-9990e1ee3791 374b6313-34a0-4c28-b336-bb2ecd879d0f 3c5a345f-3865-4420-a62c-1cdfd2defed9 5b09d7dc-8546-4ccf-9c85-de0bf4f43bf0

  • Recommend a Software for documenting work/research

    - by Rogue
    Need a software for documenting my work & research. I was considering to use blog engine but then I don't want to be playing around with backing up the databases and the matter separately. The specifications for the software would be: 1) To catalogue work by categories, tags and date. 2) Easy editing and drawing features 3) Easily incorporate saved html files into matter I'm writing, with the formatting and pictures. (probably use the mht format, don't want to be wasting timeformatting html pages) Would like the html pages to be directly displayed in the software and not opened on demand Software should be for Windows. Any recommendations? 4) Language tools could be an addition but only an optional feature

  • emacs AucTeX:Turn off auto-fill-mode inside a particular LaTeX environment

    - by Seamus
    I like using auto-fill-mode for hard line wrapping. However, when I'm making a big tabular in a .tex file, I like using align-current to have the table look somewhat like it would when printed. The difficulty is that if I have a table that is longer than the line width, auto-fill-mode breaks it, and then align-current can't put things to rights and gets confused. Is there a way to tell emacs that when I'm between the \begin and \end tags of a particular kind of environment (in this case, tabular), don't word wrap...

  • speed up the speed of a sql query to mysql?

    in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!

  • Free duplicate music finder for Mac.

    - by Jack M.
    I'm trying to clean up an mp3 folder which has a plethora of duplicate files in it due to accidentally dragging my music folder into iTunes and having it re-import songs which were already in the play list. I tried writing a quick Python app to md5 all of the files, and delete exact duplicates. This took out ~2gb of files. Unfortunately, however, this does not work on all of the duplicates because of an iTunes feature. iTunes has changed the ID3 title on some of the duplicate songs, which means the md5 of the entire file is different from the same song with a different ID3 tag. Are there any free applications out there (for the mac) which can compare the data of the actual song (ignoring ID3 tags) and determine if duplicates exist?

  • Why is Javascript's Math.floor the slowest way to calculate floor in Javascript?

    - by z5h
    I'm generally not a fan of microbenchmarks. But this one has a very interesting result. http://ernestdelgado.com/archive/benchmark-on-the-floor/ It suggests that Math.floor is the SLOWEST way to calculate floor in Javascript. ~~n, n|n, n&n all being faster. This seems pretty shocking as I would expect that people implementing Javascript in today's modern browsers would be some pretty smart people. Does floor do something important that the other methods fail to do? Is there any reason to use it?

  • Where is a good place/way to store Windows config files for Python scripts?

    - by thornomad
    I have a script/program I am working on that requires a configuration file (I am using ConfigParser). On linux, I will default to store these variables in ~/.myscript using the os.getenv('HOME') function. With Windows, I know I can use os.getenv('USERPROFILE') to find the User's "home" directory, however, is it a good idea to save a hidden file that way (ie, with the name .myscript)? I don't use Windows, obviously, but wanted to be smart about it for those who do. Is there a standard place/way to store these config variables on Windows?
