  • Easy to follow LaTeX tutorial on layout?

    - by lexu
    I want to layout a page using LaTeX and distribute text snippets/blocks in predefined locations. Something like this +--------------------------------------------------------+ | +-------------+ | | |bla bla bla| | | |bla bl ab lab| +-------------+ | | |bla bla bla| |bla bla bla| | | |bla bl ab lab| |bla bl ab lab| | | +-------------+ |bla bla bla| | | |bla bl ab lab| | | +-------------+ +----+ | | |more| | | Ich und Du |text| | | Müllers Kuh +----+ | | | +--------------------------------------------------------+ My guess is that I should go about this using a minipage or using boxes like \begin{minipage}[b][2cm]{8cm} \mbox{more} \newline \mbox{text} \newline \end{minipage} Is there a tutorial or a 'how to' page that you know, that shows me how to do this - not a list all LaTeX idioms, I have some books for that. But my books are more focused on command lists, scientific publishing and math ..

  • find rows that fall between a day and time of the week in sql server

    - by Corgalore
    I have a table of rows in MS SQL that contain a start and end day of the week, hour, and time. I need a T-SQL query that can pull rows from that table where GETDATE matches the day of week and time of those rows. Specifically, I need the query to work if a row has a day/time that starts on one day of the week and ends on the next day. Here's the structure I'm working with: _start_day_of_week (int) = 5_start_hour (int) = 15_start_minute (int) = 30 _end_day_of_week (int) = 6_end_hour (int) = 2 _end_minute (int) = 30 _title (string) = 'My Sample Row' _id (int) = 1 How would I retrieve this row given the current DATETIME?

  • Simple hardware RNG

    - by roygbiv
    I made a tongue-in-cheek comment to this question about making a hardware RNG. Does anyone know of any simple plans or can anyone descibe a simple hardware based RNG and the software to drive it? Go to Radio Shack. Buy a diode, an NTR resistor, a capacitor and serial cable. Cut off the end of the serial cable that does not fit on your computer. Solder the diode and resistor in series between pins DTR and DSR of the cable. Solder the capacitor between DSR and TXD pins. Write a small C program to do the following: Set DTR to 1. Start Timer. Monitor DSR until it goes to 1. Stop Timer. Calculate resistance from elapsed time. Retreive serveral bits from that value to use as part of random number. Repeat until enough bits have accumulated.

  • How to deal with array of checkbox values in Ruby 1.9.1?

    - by Ola Tuvesson
    In Ruby 1.9.1 strings are no longer enumerable and string.each is undefined. This causes a problem when parsing values for an array of generated checkboxes since the field value, when submitted, becomes an array of strings. For example: <% for map in Map.find(:all) %> <%= check_box_tag "listing[map_ids][]", map.id %> <%= map.title %> <% end %> This will result in an error, undefined method `each' for "1":String, in process_parameter_filter because map_ids is being passed as "map_ids"=["1","2"] (if checkboxes with values 1 and 2 have been checked that is). What is the recommended way to fix this?

  • paperclip callbacks or simple processor?

    - by holden
    I wanted to run the callback after_post_process but it doesn't seem to work in Rails 3.0.1 using Paperclip 2.3.8. It gives an error: undefined method `_post_process_callbacks' for #<Class:0x102d55ea0> I want to call the Panda API after the file has been uploaded. I would have created my own processor for this, but as Panda handles the processing, and it can upload the files as well, and queue itself for an undetermined duration I thought a callback would do fine. But the callbacks don't seem to work in Rails3. after_post_process :panda_create def panda_create video = Panda::Video.create(:source_url => mp3.url.gsub(/[?]\d*/,''), :profiles => "f4475446032025d7216226ad8987f8e9", :path_format => "blah/1234") end I tried require and include for paperclip in my model but it didn't seem to matter. Anyideas?

  • XPath and special characters

    - by Bryan
    I am having an issue with an XPath query I'm performing for a Sitecore CMS system. This query works fine: /root/content/Meta-Data/Tips/* But when I try this: /root/content/Meta-Data/Tips/*[@SomeAttribute='somekey'] I get an error which says "End of string expected at position 22" which is where the dash character is found. I was under the impression that the dash was not a special character in XML... am I doing something wrong here? Do I need to encode this in some way? Or is this a bug in the XPath parser? Any suggested workarounds?

    Can C/C++ be choice of keeping all your logic (business/domain) for web application? Why? I've two resources (cousins) having knowledge on C/C++ and me also good in C/C++, Python, HTML, CSS and JavaScript. We like to utilize our free time to work on our some good ideas we developed together. The ideas require knowledge of web application development. And I'm the only one who has it. Is there a way they developed the core in C/C++ and I do the rest of scripting for front-end development? Thanks.

  • Good way to find duplicate files?

    - by OverTheRainbow
    Hello I don't know enough about VB.Net (2008, Express Edition) yet, so I wanted to ask if there were a better way to find files with different names but the same contents, ie. duplicates. In the following code, I use GetFiles() to retrieve all the files in a given directory, and for each file, use MD5 to hash its contents, check if this value already lives in a dictionary: If yes, it's a duplicate and I'll delete it; If not, I add this filename/hashvalue into the dictionary for later: 'Get all files from directory Dim currfile As String For Each currfile In Directory.GetFiles("C:\MyFiles\", "File.*") 'Check if hashing already found as value, ie. duplicate If StoreItem.ContainsValue(ReadFileMD5(currfile)) Then 'Delete duplicate 'This hashing not yet found in dictionary -> add it Else StoreItem.Add(currfile, ReadFileMD5(currfile)) End If Next Is this a good way to solve the issue of finding duplicates, or is there a better way I should know about? Thank you.

  • Django ORM and PostgreSQL connection limits

    - by bennylope
    I'm running a Django project on Postgresql 8.1.21 (using Django 1.1.1, Python2.5, psycopg2, Apache2 with mod_wsgi 3.2). We've recently encountered this lovely error: OperationalError: FATAL: connection limit exceeded for non-superusers I'm not the first person to run up against this. There's a lot of discussion about this error, specifically with psycopg, but much of it centers on older versions of Django and/or offer solutions involving edits to code in Django itself. I've yet to find a succinct explanation of how to solve the problem of the Django ORM (or psycopg, whichever is really responsible, in this case) leaving open Postgre connections. Will simply adding connection.close() at the end of every view solve this problem? Better yet, has anyone conclusively solved this problem and kicked this error's ass?

  • How can I loop through variables in SPSS? I want to avoid code duplication.

    - by chucknelson
    Is there a "native" SPSS way to loop through some variable names? All I want to do is take a list of variables (that I define) and run the same procedure for them: pseudo-code - not really a good example, but gets the point across... for i in varlist['a','b','c'] do FREQUENCIES VARIABLES=varlist[i] / ORDER=ANALYSIS. end I've noticed that people seem to just use R or Python SPSS plugins to achieve this basic array functionality, but I don't know how soon I can get those configured (if ever) on my installation of SPSS. SPSS has to have some native way to do this...right?

  • Silverlight MEF Embedded Resources

    - by Fastidious
    I have two different Silverlight UserControls imported with MEF from two different xaps. The UserControls are simply an Image on a Canvas. Both UserControls have the image marked as 'Resource'. The images are different but their names are the same (key point). I'm not quite sure what's going on behind the scenes of the MEF import but both images seem to end up in the same AppDomain. After the composition when I stick the UserControls on a Canvas, each is an instance of the class it should be, but they both show the same image. Obviously if the image file names are unique across all xaps I import I have no problem but I don't like that solution. Is there a better one?

    I have an array of Paths which i want to read out with Template Toolkit. How can I access the array Elements of this array? The Situation is this: my @dirs; opendir(DIR,'./directory/') || die $!; @dirs = readdir(DIR); close DIR; $vars->{'Tree'} = @dirs; Then I call the Template Page like this: $template->process('create.tmpl', $vars) || die "Template process failed: ", $template->error(), "\n"; In this template I want to make an Tree of the directories in the array. How can I access them? My idea was to start with a foreach in the template like this [% FOREACH dir IN Tree.dirs %] $dir [% END %]

  • cakePHP - ACL tutorial & SQL Error: 1104

    Greetings! I run into a problem/bug in production environment with SQL Error: 1104 when deploying a project secured with the ACL tutorial. The full error: SQL Error: 1104: The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay [CORE/cake/libs/model/datasources/dbo_source.php, line 666] I've build a small site, worked through the ACL tutorial from the official cake book and locally everything is spiffy. dev. setup consists of: XAMPP: myslq 5.1.33, php 5.3 cakePHP 1.2.7 prod. setup: mysql 5.0.33 php 5.2.2 One of the differences I noticed with mysql setup between local and production servers, is that SQL_BIG_SELECTS is disabled on the production server ( and I don't have privileges to change that, posted a support ticked, didn't hear anything yet) Is there anything I can do about this from my end? Thanks in advance.

  • Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

    - by Laurence Gonsalves
    Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

    Hi, Say, I have an array that looks like this: var playlist = [ {artist:"Herbie Hancock", title:"Thrust"}, {artist:"Lalo Schifrin", title:"Shifting Gears"}, {artist:"Faze-O", title:"Riding High"} ]; How can move an element to another position? I want to move for example, {artist:"Lalo Schifrin", title:"Shifting Gears"} to the end. I tried using splice, like this: var tmp = playlist.splice(2,1); playlist.splice(2,0,tmp); But it doesn't work. Any help would be appreciated.

  • Gradient a Parallelogram

    - by nuclearpenguin
    I'm working in JavaScript drawing on a canvas, and have four coordinates to draw a parallelogram, called A, B, C, and D starting from the top-left, top-right, bottom-left, and bottom right, respectively. An example of some coordinates might be: A: (3, 3) B: (4, 3) C: (1, 0) D: (2, 0) I can draw the parallelogram just fine, but I would like to fill it in with a gradient. I want the gradient to fill in from left to right, but matching the angle of the shape. The library I use (CAKE) requires a start and stop coordinate for the gradient. My stop and start would be somewhere half way between A and C, and end somewhere half way between B and D. Of course, it is not simply EXACTLY half way because the angles at A, B, C, and D are not right angles. So given this information (the coordinates), how to I find the point on the line A - C to start, and the point on the line B - D to stop? Remember, I'm doing this in JavaScript, so I have some good Math tools at my disposal for calculation.

    So I have Image like this I want to get something like this (I hevent drawn all lines I want but I hope you can get my idea) I want to use SURF ( (Speeded Up Robust Features) is a robust image descriptor, first presented by Herbert Bay et al. in 2006 ) or something that is based on sums of 2D Haar wavelet responses and makes an efficient use of integral images for finding all straight lines on image. I want to get relative to picture pixel coords start and end points of lines. So on this picture to find all lines between tiles and thouse 2 black lines on top. Is there any such Code Example (with lines search capability) to start from? I love C and C++ but any other readable code will probably work for me=)

  • Can you find a pattern to sync files knowing only dates and filenames?

    - by Robert MacLean
    Imagine if you will a operating system that had the following methods for files Create File: Creates (writes) a new file to disk. Calling this if a file exists causes a fault. Update File: Updates an existing file. Call this if a file doesn't exist causes a fault. Read File: Reads data from a file. Enumerate files: Gets all files in a folder. Files themselves in this operating system only have the following meta data: Created Time: The original date and time the file was created, by the Create File method. Modified Time: The date and time the file was last modified by the Update File method. If the file has never been modified, this will equal the Create Time. You have been given the task of writing an application which will sync the files between two directories (lets call them bill and ted) on a machine. However it is not that simple, the client has required that The application never faults (see methods above). That while the application is running the users can add and update files and those will be sync'd next time the application runs. Files can be added to either the ted or bill directories. File names cannot be altered. The application will perform one sync per time it is run. The application must be almost entirely in memory, in other words you cannot create a log of filenames and write that to disk and then check that the next time. The exception to point 6 is that you can store date and times between runs. Each date/time is associated with a key labeled A through J (so you have 10 to use) so you can compare keys between runs. There is no way to catch exceptions in the application. Answer will be accepted based on the following conditions: First answer to meet all requirements will be accepted. If there is no way to meet all requirements, the answer which ensures the smallest amount of missed changes per sync will be accepted. A bounty will be created (100 points) as soon as possible for the prize. The winner will be selected one day before the bounty ends. Please ask questions in the comments and I will gladly update and refine the question on those.

  • Possible typos in ECMAScript 5 specification?

    - by Andy West
    Does anybody know why, at the end of section 7.6 of the ECMA-262, 5th Edition specification, the nonterminals UnicodeLetter, UnicodeCombiningMark, UnicodeDigit, UnicodeconnectorPunctuation, and UnicodeEscapeSequence are not followed by two colons? From section 5.1.6: Nonterminal symbols are shown in italic type. The definition of a nonterminal is introduced by the name of the nonterminal being defined followed by one or more colons. (The number of colons indicates to which grammar the production belongs.) Since lexical productions are distinguished by having two colons, and this is under "Lexical Conventions", I'm assuming that they meant to put the colons in. Does that sound right? Just making sure that these really are nonterminals and they really are part of the lexical grammar. EDIT: I noticed there have been votes to close this. Just to make my case about why this is programming-related, it is relevant to anyone wanting to implement an ECMAScript interpreter.

  • Unable to use Client Application Services with custom MembershipProvider.

    - by Shimmy
    Hi, I have a Windows-Forms Application that I configured to use with an ASP.NET Service that is an Authentication service using a custom MembershipProvider. When I call Membership.CreateUser in the Windows Application a NotSupportedException is thrown telling: "Specified method is not supported.". I tried creating a web page in the website and test the MembershipProvider, everything works just fine when woeking from within the website. Any ideas or link for how to use custom (not SqlMembershipProvider) MembershipProvider will be really appreciated! Edit: The method ValidateUser does work. The overriden CreateUser doesn't work I tried Override Sub CreateUser(.......) As MembershipUser Return New User() End Sub But I still get the same excetption as before.
