• Bash script "read" not pausing for user input when executed from SSH shell

  - by Aaron Hancock

  I'm new to Bash scripting, so please be gentle. I'm connected to a Ubuntu server via SSH (PuTTY) and when I run this command, I expect the bash script that downloads and executes to allow user input and then echo that input. It seems to just write out the echo label for the input request and terminate. wget -O - https://raw.github.com/aaronhancock/pub/master/bash/readtest.sh | bash Any clue what I might be doing wrong? UPDATE: This bash command does exactly what I wanted bash <(wget -q -O - https://raw.github.com/aaronhancock/pub/master/bash/readtest.sh)

• Calling linux utilities with options from within a Bash script.

  - by Kyle

  This is my first Bash script so forgive me if this question is trivial. I need to count the number of files within a specified directory $HOME/.junk. I thought this would be simple and assumed the following would work: numfiles= find $HOME/.junk -type f | wc -l echo "There are $numfiles files in the .junk directory." Typing find $HOME/.junk -type f | wc -l at the command line works exactly how I expected it to, simply returning the number of files. Why is this not working when it is entered within my script? Am I missing some special notation when it comes to passing options to the utilities? Thank you very much for your time and help.

• mcrypt decoding errors

  - by Kyle Hudson

  Hi, I have a few issues with the following php functions (part of a bigger class). //encode public function acc_pw_enc($text, $key) { $text_num = str_split($text, 8); $text_num = 8 - strlen($text_num[count($text_num)-1]); for ($i=0; $i < $text_num; $i++) { $text = $text . chr($text_num); } $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', ''); mcrypt_generic_init($cipher, $key, 'fYfhHeDm'); $decrypted = mcrypt_generic($cipher, $text); mcrypt_generic_deinit($cipher); return base64_encode($decrypted); } //decode public function acc_pw_dec($encrypted_text, $key) { $cipher = mcrypt_module_open(MCRYPT_TRIPLEDES, '', 'cbc', ''); mcrypt_generic_init($cipher, $key, 'fYfhHeDm'); $decrypted = mdecrypt_generic($cipher, base64_decode($encrypted_text)); mcrypt_generic_deinit($cipher); $last_char = substr($decrypted, -1); for($i=0; $i < 8-1; $i++) { if(chr($i) == $last_char) { $decrypted = substr($decrypted, 0, strlen($decrypted)-$i); break; } } return rtrim($decrypted); //str_replace("?", "", $decrypted); } So for exampe if i encrypt the string 'liloMIA01' with the salt/key 'yBevuZoMy' i will get '7A30ZkEjYbDcAXLgGE/6nQ=='. I get liloMIA01 as the decrypted value, i tried using rtrim but it didn't work.

• Talking to an Authentication Server

  - by Kyle Terry

  I'm building my startup and I'm thinking ahead for shared use of services. So far I want to allow people who have a user account on one app to be able to use the same user account on another app. This means I will have to build an authentication server. I would like some opinions on how to allow an app to talk to the authentication server. Should I use curl? Should I use Python's http libs? All the code will be in Python. All it's going to do is ask the authentication server if the person is allowed to use that app and the auth server will return a JSON user object. All authorization (roles and resources) will be app independent, so this app will not have to handle that. Sorry if this seems a bit newbish; this is the first time I have separated authentication from the actual application.

• jQuery event handling with .live() problem with setInterval and clearInterval

  - by Kyle Lafkoff

  jQuery 1.4.2: I have an image. When the mouseover event is triggered, a function is executed that runs a loop to load several images. On the contrary, the mouseout event needs to set the image back to a predetermined image and no longer have the loop executing. These are only for the images with class "thumb": $("img.thumb").live("mouseover mouseout", function(event) { var foo = $(this).attr('id'); var wait; var i=0; var image = document.getElementById(foo); if (event.type == 'mouseover') { function incrementimage() { i++; image.src = 'http://example.com/images/file_'+i+'.jpg'; if(i==30) {i=0;} } wait = setInterval(incrementimage,500); } else if (event.type == 'mouseout') { clearInterval (wait); image.src = 'http://example.com/images/default.jpg'; } return false; }); When I mouseout, the image is set to the default.jpg but the browser continues to loop though the images. It will never stop. Can someone hit me with some knowledge? Thanks.

• CSS Negative margins for positioning.

  - by Kyle Sevenoaks

  Is it ok to use negative margins for positioning? I have a lot in my current site and feel like it's not such a stable way to position things. I usually suggest to use them too. For example I have a checkout page with three divs on top of each other <div class="A"> header </div> <div class="B"> content </div> <div class="C"> footer </div> (A, B and C), which are meant to sit on top of each other, to appear attached. I did this using: .B { margin-top: -20px; } On div B, to meet the bottom of div A. Is this good practice or shall I re-code using top and left?

• Writing a factory for classes that have required arguments

  - by Kyle Adams

  I understand the concept of factory pattern such that you give it something it spits out something of the same template back so if I gave a factory class apple, I expect to get many apples back with out having to instantiate a new apple ever time. what if that apple has a required argument of seed, or multiple required arguments of seed, step and leaf? how do you use factory pattern here? that is how do I use factory pattern to instantiate this: $apple = new Apple($seed, $stem, $leaf);

• What is the proper use of boost::fusion::push_back?

  - by Kyle

  // ... snipped includes for iostream and fusion ... namespace fusion = boost::fusion; class Base { protected: int x; public: Base() : x(0) {} void chug() { x++; cout << "I'm a base.. x is now " << x << endl; } }; class Alpha : public Base { public: void chug() { x += 2; cout << "Hi, I'm an alpha, x is now " << x << endl; } }; class Bravo : public Base { public: void chug() { x += 3; cout << "Hello, I'm a bravo; x is now " << x << endl; } }; struct chug { template<typename T> void operator()(T& t) const { t->chug(); } }; int main() { typedef fusion::vector<Base*, Alpha*, Bravo*, Base*> Stuff; Stuff stuff(new Base, new Alpha, new Bravo, new Base); fusion::for_each(stuff, chug()); // Mutates each element in stuff as expected /* Output: I'm a base.. x is now 1 Hi, I'm an alpha, x is now 2 Hello, I'm a bravo; x is now 3 I'm a base.. x is now 1 */ cout << endl; // If I don't put 'const' in front of Stuff... typedef fusion::result_of::push_back<const Stuff, Alpha*>::type NewStuff; // ... then this complains because it wants stuff to be const: NewStuff newStuff = fusion::push_back(stuff, new Alpha); // ... But since stuff is now const, I can no longer mutate its elements :( fusion::for_each(newStuff, chug()); return 0; }; How do I get for_each(newStuff, chug()) to work? (Note: I'm only assuming from the overly brief documentation on boost::fusion that I am supposed to create a new vector every time I call push_back.)

• Truncate all tables in postgres database

  - by Aaron

  I regularly need to delete all the data from my postgresql database before a rebuild. How would I do this directly in SQL? At the moment I've managed to come up with a SQL statement that returns all the commands I need to execute: SELECT 'TRUNCATE TABLE ' || tablename || ';' FROM pg_tables WHERE tableowner='MYUSER'; but I cant see a way to execute them programatically once I have them... Thanks in advance

• Counting multiple entries in a MySQL database?

  - by Aaron

  Hi all, I'm trying to count multiple entries in a MySQL database, I know how to use COUNT(), but the exact syntax I want to get the results I need eludes me. The problem: Table structure: ID, CODE, AUTHOR, COUNTRY, TIMESTAMP. Code, Author and Country overlap many times in the table. I am trying to discover if there is one simple query that can be ran to return (using WHERE clause on COUNTRY) the author field, the code field, and then a final field that counts the number of times the CODE was present in the query result. So, theoretically I could end up with an array like: array('author', 'code', 'codeAppearsNTimes'); Authors also have varying codes associated with them, so I don't want the results merged. I suppose the end result would be: 'This author is associated with this code this many times'. Is this possible with MySQL? Thanks in advance.

• Flickr API automated login using Python library flickrapi

  - by Dave Aaron Smith

  I have a web application that I want to sync with Flickr. I don't want the users to have to log into Flickr so I plan to use a single login. I believe I'll need to do something like this: import flickrapi flickr = flickrapi.FlickrAPI(myKey, mySecret) (token, frob) = flickr.get_token_part_one(perms='write', my_auth_callback) flickr.get_token_part_two((token, frob,)) flickr.what_have_you(... I don't know what my_auth_callback should look like though. I suspect it will have to post my login information to flickr. Could I do the get_token_part_one step just once manually perhaps and then re-use it in get_token_part_two?

• sharing web user controls across projects.

  - by Kyle

  I've done this using a regular .cs file that just extends System.Web.UI.UserControl and then included the assembly of the project that contains the control into other projects. I've also created .ascx files in one project then copied all ascx files from a specified folder in the properties-Build Events-Pre-build event. Now what I want to do is a combination of those two: I want to be able to use ascx files that I build in one project, in all of my other projects but I want to include them just using assembly references rather than having to copy them to my "secondary" projects as that seems a ghetto way to accomplish what I want to do. It works yes, but it's not very elegant. Can anyone let me know if this even possible, and if so, what the best way to approach this is?

• Nhibernate criteria query inserts an extra order by expression when using JoinType.LeftOuterJoin and Projections

  - by Aaron Palmer

  Why would this nhibernate criteria query produce the sql query below? return Session.CreateCriteria(typeof(FundingCategory), "fc") .CreateCriteria("FundingPrograms", "fp") .CreateCriteria("Projects", "p", JoinType.LeftOuterJoin) .Add(Restrictions.Disjunction() .Add(Restrictions.Eq("fp.Recipient.Id", recipientId)) .Add(Restrictions.Eq("p.Recipient.Id", recipientId)) ) .SetProjection(Projections.ProjectionList() .Add(Projections.GroupProperty("fc.Name"), "fcn") .Add(Projections.Sum("fp.ObligatedAmount"), "fpo") .Add(Projections.Sum("p.ObligatedAmount"), "po") ) .AddOrder(Order.Desc("fpo")) .AddOrder(Order.Desc("po")) .AddOrder(Order.Asc("fcn")) .List<object[]>(); SELECT this_.Name as y0_, sum(fp1_.ObligatedAmount) as y1_, sum(p2_.ObligatedAmount) as y2_ FROM fundingCategories this_ inner join fundingPrograms fp1_ on this_.fundingCategoryId = fp1_.fundingCategoryId left outer join projects p2_ on fp1_.fundingProgramId = p2_.fundingProgramId WHERE (fp1_.recipientId = 6 /* @p0 */ or p2_.recipientId = 6 /* @p1 */) GROUP BY this_.Name ORDER BY p2_.name asc, y1_ desc, y2_ desc, y0_ asc It is incorrectly putting the p2_name asc into the ORDER BY statement, and causing it to crash. This only happens when I use JoinType.LeftOuterJoin on my Projects criteria. Is this a known nhibernate bug? I'm using nhibernate 2.0.1.4000. Thanks for any insight.

• Location of the fonts on the iPhone?

  - by Kyle

  I'm using the FreeType2 library in an iPhone project, and I'm trying to simply load a TTF file from the system, if possible. FT_Library library; FT_Face face; int error; error = FT_Init_FreeType( &library ); if ( error == 0 ) printf("Initialized FreeType2\r\n"); /* Prints */ error = FT_New_Face(library, "/System/Library/Fonts/Helvetica.ttf", 0, &face); if ( error == FT_Err_Cannot_Open_Resource ) printf("Font not found\r\n"); /* Prints */ That error seems to be for file not found. Is /System/Library/Fonts not the location of the fonts? Or, do iPhone apps simply not have any read access at all to that directory. Thanks!

• Super simple CSS tooltip in a table, why is it not displaying and can I make it work?

  - by Kyle Sevenoaks

  Hi, I have been trying to implement many different tooltips on this page for my client, he's adamant that we have a picture of the product show up when you hover over the product name in the order page. I decided to use the super simple CSS tooltip, it's very easy to implement and does exactly what we want. It works on a dynamic page, the others I tried didn't. I have made an example here: CSS tooltip in table example. This page used to be displayed using divs, I have since changed it to a table, as it's tabular data and easier to work with. It worked fine when it used divs, now it's in a table, it won't display the span on hover. My questions are: Why is it not working? How can I make it work? If not, does anyone know another super easy to implement tooltip that can work properly on a dynamic page? Here's the DIV tooltip for reference: DIV display tooltip. Edit: Just noticed it kinda half works in IE8. Thanks.

• How do I draw the points in an ESRI Polyline, given the bounding box as lat/long and the "points" as

  - by Aaron

  I'm using OpenMap and I'm reading a ShapeFile using com.bbn.openmap.layer.shape.ShapeFile. The bounding box is read in as lat/long points, for example 39.583642,-104.895486. The bounding box is a lower-left point and an upper-right point which represents where the points are contained. The "points," which are named "radians" in OpenMap, are in a different format, which looks like this: [0.69086486, -1.8307719, 0.6908546, -1.8307716, 0.6908518, -1.8307717, 0.69085056, -1.8307722, 0.69084936, -1.8307728, 0.6908477, -1.8307738, 0.69084626, -1.8307749, 0.69084185, -1.8307792]. How do I convert the points like "0.69086486, -1.8307719" into x,y coordinates that are usable in normal graphics? I believe all that's needed here is some kind of conversion, because bringing the points into Excel and graphing them creates a line whose curve matches the curve of the road at the given location (lat/long). However, the axises need to be adjusted manually and I have no reference as how to adjust the axises, since the given bounding box appears to be in a different format than the given points. The ESRI Shapefile technical description doesn't seem to mention this (http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf).

• Opinion on "loop invariants", and are these frequently used in the industry?

  - by Michael Aaron Safyan

  I was thinking back to my freshman year at college (five years ago) when I took an exam to place-out of intro-level computer science. There was a question about loop invariants, and I was wondering if loop invariants are really necessary in this case or if the question was simply a bad example... the question was to write an iterative definition for a factorial function, and then to prove that the function was correct. The code that I provided for the factorial function was as follows: public static int factorial(int x) { if ( x < 0 ){ throw new IllegalArgumentException("Parameter must be = 0"); }else if ( x == 0 ){ return 1; }else{ int result = 1; for ( int i = 1; i <= x; i++ ){ result*=i; } return result; } } My own proof of correctness was a proof by cases, and in each I asserted that it was correct by definition (x! is undefined for negative values, 0! is 1, and x! is 1*2*3...*x for a positive value of x). The professor wanted me to prove the loop using a loop invariant; however, my argument was that it was correct "by definition", because the definition of "x!" for a positive integer x is "the product of the integers from 1... x", and the for-loop in the else clause is simply a literal translation of this definition. Is a loop invariant really needed as a proof of correctness in this case? How complicated must a loop be before a loop invariant (and proper initialization and termination conditions) become necessary for a proof of correctness? Additionally, I was wondering... how often are such formal proofs used in the industry? I have found that about half of my courses are very theoretical and proof-heavy and about half are very implementation and coding-heavy, without any formal or theoretical material. How much do these overlap in practice? If you do use proofs in the industry, when do you apply them (always, only if it's complicated, rarely, never)?

• Using diff and patch to force one local code base to look like another

  - by Dave Aaron Smith

  I've noticed this strange behavior of diff and patch when I've used them to force one code base to be identical to another. Let's say I want to update update_me to look identical to leave_unchanged. I go to update_me. I run a diff from leave_unchanged to update_me. Then I patch the diff into update_me. If there are new files in leave_unchanged, patch asks me if my patch was reversed! If I answer yes, it deletes the new files in leave_unchanged. Then, if I simply re-run the patch, it correctly patches update_me. Why does patch try to modify both leave_unchanged and update_me? What's the proper way to do this? I found a hacky way which is to replace all +++ lines with nonsense paths so patch can't find leave_unchanged. Then it works fine. It's such an ugly solution though. $ mkdir copyfrom $ mkdir copyto $ echo "Hello world" > copyfrom/myFile.txt $ cd copyto $ diff -Naur . ../copyfrom > my.diff $ less my.diff diff -Naur ./myFile.txt ../copyfrom/myFile.txt --- ./myFile.txt 1969-12-31 19:00:00.000000000 -0500 +++ ../copyfrom/myFile.txt 2010-03-15 17:21:22.000000000 -0400 @@ -0,0 +1 @@ +Hello world $ patch -p0 < my.diff The next patch would create the file ../copyfrom/myFile.txt, which already exists!

• Storing an object to use in multiple classes

  - by Aaron Sanders

  I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. Let me set up my problem for you: We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings. I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration. The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later. Sorry if this is confusing. If you have questions, let me know and I will answer them. Thanks for your help.

• perl hashes - comparing keys and values

  - by Aaron Moodie

  I've been reading over the perl doc, but I can't quite get my head around hashes. I'm trying to find if a hash key exists, and if so, compare is't value. The thing that is confusing me is that my searches say that you find if a key exists by if (exists $files{$key}) , but that $files{$key} also gives the value? the code i'm working on is: foreach my $item(@new_contents) { next if !-f "$directory/$item"; my $date_modified = (stat("$directory/$item"))[9]; if (exists $files{$item}) { if ($files{$item} != $date_modified { $files{$item} = $date_modified; print "$item has been modified\n"; } } else { $files{$item} = $date_modified; print "$item has been added\n"; } }
