• How to safely purge in Varnish if backend is sick without losing content

  - by Highway of Life

  If the backend is sick, what is the preferable way to ensure that stale content can be retrieved from the backend when a PURGE request is made? When a PURGE request is made, whether or not the backend is sick, by default the content will be eliminated from the Varnish cache and if the backend is down, a 503 page would be served to the user until the backend comes back online to serve a new version of the content. I'd like to be able to at least serve up a stale version of the content if a new version could not be retrieved from the backend. Is this possible without installing the Softpurge Varnish Mod?

• Fibonacci Sequence using loop and recur

  - by AdamJMTech

  I am doing the Project Euler challenge in Clojure and I want to find the sum of all the even numbers in a fibonacci sequence up to a certain number. The code for a function that does this is below. I know there are quicker and easier ways of doing this, I am just experimenting with recursion using loop and recur. However the code doesn't seem to work it never returns an answer. (defn fib-even-sum [upto] (loop [previous 1 nxt 1 sum 0] (if (or (<= upto 1) (>= nxt upto)) sum) (if (= (mod nxt 2) 0) (recur nxt (+ previous nxt) (+ sum nxt)) (recur nxt (+ previous nxt) sum)))) I was not sure if I could do recur twice in the same loop or not. I'm not sure if this is causing the problem?

• cahoots - zend framework application is not running

  - by Gaurav Sharma

  hello everyone, I downloaded cahoots from sourceforge.net. It is a zend framework application. Very nicely done and I must say that it should be a nice tutorial for everyone who is struggling to learn Zend framework. But my problem is that even after reading the instructions this application is still not running. The application just doesn't run at all giving an error message. I have tried my best. no success :( Also I wanted to execute the application as "http://localhost/cahoots" but it runs by this URL "http://localhost/cahoots/public". why is it so.? I am using XAMPP v 1.7.1 with mod-rewrite enabled. Please guide me through the process. Any good tutorials on zend framework with zend tool would be appreciable. I want to learn this framework. Thanks

• A quick over view of facebook's db?

  - by Matt

  Hey guys I find it hard to believe that Facebook uses simple sql, surely it would use some other method but lets assume for now it does use sql how would the code assimilating the 'wall' work? Lets say that there is three tables (just for the example) Friends: id (entry key) - uid(your id) - fid (your mates' id) Wall:id (entry key) - username - comment - time - commentcount comments: id (entry key) - wid (wall id (original comment)) - reply - time Lets forget about the like part and report etc, as well as mod things (ip, ban etc.) How would this work? Select wall.id, wall.username, wall.comment, wall.time, wall.commentcount, comments.wid, comments.reply, comments.time FROM wall inner join comments ON wall.id=comments.wid ORDER BY wall.time; That's your own wall but how do they get friend's? A heap of unions?

• How can I re-size and re-position a shadowbox/greybox window to display in a certain div element?

  - by kielie

  Hi guys, I would like to know if it is possible to re-size and re-position a greybox or shadowbox window to display in a certain div element? I am creating a template for a wordpress site, and I am using the default calendar, but when you click on a date inside of the calendar, the default action is to open it up in a new window. Would it be possible to mod greybox or shadowbox in such a way that when you click on a date, the box opens up over the calendar displaying the contents in it, instead of a new page? Or is there another way of achieving the desired result, maybe with jQuery or Javascript? Any help would be greatly appreciated, thanx in advance!

• ExpressionEngine 2 module "tag cannot be processed"

  - by Phil Sturgeon

  So I have turned my hand to ExpressionEngine and while the backend crud was easy enough getting the frontend working with template syntax is proving difficult, even at the "hello world" level. expressionengine/third_party/rest/mod.rest.php class Rest { var $return_data = ''; function Rest() { $this->EE =& get_instance(); return $this->return_data = 'HAI'; } } // END REST Class /* End of file REST.php */ /* Location: ./application/libraries/REST.php */ Then im calling it directly in a new empty template: {exp:rest} So I'm expecting to see "HAI" but I get: Error The following tag cannot be processed: {exp:rest} Please check that the ‘rest’ module is installed and that ‘rest’ is an available method of the module Any ideas? The module is installed and the backend is running fine.

• Reading a client's header from Python CGI script?

  - by jawonlee

  I'm writing a very simple web service, written in Python and run as CGI on an Apache server. According to Python docs (somewhere... I forgot where), I can use sys.stdin to read the data POSTed by a random client, and this has been working fine. However, I would like to be able to read the HTTP header information as well - incoming IP, user agent, and so on. I'd also like to keep it very simple for now, by using only Python libraries (so no mod-python). How do I do this?

• Recursive function causing a stack overflow

  - by dbyrne

  I am trying to write a simple sieve function to calculate prime numbers in clojure. I've seen this question about writing an efficient sieve function, but I am not to that point yet. Right now I am just trying to write a very simple (and slow) sieve. Here is what I have come up with: (defn sieve [potentials primes] (if-let [p (first potentials)] (recur (filter #(not= (mod % p) 0) potentials) (conj primes p)) primes)) For small ranges it works fine, but causes a stack overflow for large ranges: user=> (sieve (range 2 30) []) [2 3 5 7 11 13 17 19 23 29] user=> (sieve (range 2 15000) []) java.lang.StackOverflowError (NO_SOURCE_FILE:0) I thought that by using recur this would be a non-stack-consuming looping construct? What am I missing?

• How do I get the sums of the digits of a large number in Haskell?

  - by Tim

  I'm a C++ Programmer trying to teach myself Haskell and it's proving to be challenging grasping the basics of using functions as a type of loop. I have a large number, 50!, and I need to add the sum of its digits. It's a relatively easy loop in C++ but I want to learn how to do it in Haskell. I've read some introductory guides and am able to get 50! with sum50fac.hs:: fac 0 = 1 fac n = n * fac n - 1 x = fac 50 main = print x Unfortunately at this point I'm not entirely sure how to approach the problem. Is it possible to write a function that adds (mod) x 10 to a value and then calls the same function again on x / 10 until x / 10 is less than 10? If that's not possible how should I approach this problem? Thanks!

• Apache, and logrotate instances

  - by OlivierDofus

  Hi! If I have one website and I want to rotate its logs, there's one instance of logrotate that is launched. There are as many logrotate instances launched as they are virtual websites. Here you can find mod_log_rotate, with a 1.3 version and (only) 2.0 version: http://www.hexten.net/wiki/index.php/Mod-log-rotate It's 6 years old. Is there something new, or maybe is there something like that in recent Apache versions? I didn't find anything like that, and I don't know if this code is still "usable" for recent Apache versions (2.2.x) Don't hesitate to edit my post to make it proper English, thanks a lot!

• is this a correct way to generate rsa keys?

  is this code going to give me correct values for RSA keys (assuming that the other functions are correct)? im having trouble getting my program to decrypt properly, as in certain blocks are not decrypting properly this is in python: import random def keygen(bits): p = q = 3 while p == q: p = random.randint(2**(bits/2-2),2**(bits/2)) q = random.randint(2**(bits/2-2),2**(bits/2)) p += not(p&1) # changes the values from q += not(q&1) # even to odd while MillerRabin(p) == False: # checks for primality p -= 2 while MillerRabin(q) == False: q -= 2 n = p * q tot = (p-1) * (q-1) e = tot while gcd(tot,e) != 1: e = random.randint(3,tot-1) d = getd(tot,e) # gets the multiplicative inverse while d<0: # i can probably replace this with mod d = d + tot return e,d,n one set of keys generated: e = 3daf16a37799d3b2c951c9baab30ad2d d = 16873c0dd2825b2e8e6c2c68da3a5e25 n = dc2a732d64b83816a99448a2c2077ced

• How to accomplish "AuthType None" in Apache 2.2

  - by Technorati

  http://httpd.apache.org/docs/trunk/mod/mod_authn_core.html#authtype talks about "AuthType None", and has an awesome example of exactly what I need to do - unfortunately, it appears to be new to 2.3/2.4. Is there any equivalent feature in 2.2? The authentication type None disables authentication. When authentication is enabled, it is normally inherited by each subsequent configuration section, unless a different authentication type is specified. If no authentication is desired for a subsection of an authenticated section, the authentication type None may be used; in the following example, clients may access the /www/docs/public directory without authenticating: <Directory /www/docs> AuthType Basic AuthName Documents AuthBasicProvider file AuthUserFile /usr/local/apache/passwd/passwords Require valid-user </Directory> <Directory /www/docs/public> AuthType None Require all granted </Directory>

• How can I selectively override a django .count() method

  - by Tom Viner

  I'm using postGresSQL and my main table has about 20,000 rows. Sometimes count() methods can take ages or even timeout. Mod.manager.filter(...).count() I need to selectively override the count() method depending on what filter has been applied. Just having a cache of results would be a great gain but I'd like to be able to say: if filter query is just {'enabled'=True} then return 20,000 without touching the db. Note: I can't prevent the call to .count() as it's inside django's pagination, which always does a count.

• HOw to Extract image pixels and perform computation on it

  - by gavishna

  What i want to do is extract the pixels into array A(i,j).Let A(i,j) represent the pixel in the ith row & jth colm of the image. Let B(i,j) be the transformed array containing bits such that B(i,j) = 1 if (A(i,j)/2^t) mod 2 =1, where t=0,1,2,3,4,5,6,7 = 0 otherwise Then the array B(i,j) will be mutliplied by another array say C(i,j) representing another image. Then i want to plot the result of B*C as an image. How do i take in the pixels for the above conditions for both gray and RGB color format.Also how do i solve the above problem.Any helo will be usefull because i am not an expert in image processing.

• Java application failing on special characters.

  - by Scottm

  An application I am working on reads information from files to populate a database. Some of the characters in the files are non-English, for example accented French characters. The application is working fine in Windows but on our Solaris machine it is failing to recognise the special characters and is throwing an exception. For example when it encounters the accented e in "Gérer" it says :- Encountered: "\u0161" (353), after : "\'G\u00c3\u00a9rer les mod\u00c3" (an exception which is thrown from our application) I suspect that in order to stop this from happening I need to change the file.encoding property of the JVM. I tried to do this via System.setProperty() but it has not stopped the error from occurring. Are there any suggestions for what I could do? I was thinking about setting the basic locale of the solaris platform in /etc/default/init to be UTF-8. Does anyone think this might help? Any thoughts are much appreciated.

• Fast, Vectorizable method of taking floating point number modulus of special primes?

  - by caffiend

  Is there a fast method for taking the modulus of a floating point number? With integers, there are tricks for Mersenne primes, so that its possible to calculate y = x MOD 2^31 without needing division. Can any similar tricks be applied for floating point numbers? Preferably, in a way that can be converted into vector/SIMD operations, or moved into GPGPU code. The primes I'm interested in would be 2^7 and 2^31, although if there are more efficient ones for floating point numbers, those would be welcome.

• How do you share pre-calculated data between calls to a Rails web service?

  - by Nigel Thorne

  I have a Rails app that allows users to build up a network structure and then ask questions about how to navigate around it. When adding nodes and connections these are just saved to the database. At the point you make a query of the network I calculate the shortest path from any node to any other node. Constructing this in memory takes a while (something I need to fix), but once it is there, you can instantly get the answer to any of these path questions. The question is... How do I share this network between calls to the website, so each request doesn't regenerate the paths network each time? Note: I am hosting this on apache server using passenger (mod ruby) Thoughts?

• How to efficiently implement a blocking call with Rails, while letting the client wait for the reply

  - by Kyle Heironimus

  We have a web service written in Rails. The API is published and we cannot change it. Our app communicates with a remote web service that sometimes hangs or takes several seconds to reply. Client -> Our Web Service -> Remote Web Service Currently, if the remote web service hangs for 5 seconds, one of our rails processes on our web service also hangs with it, which is what we need to avoid. I've seen things such as mod-x-sendfile, modporter, and delayed jobs, but the best I can tell, they all assume the client is not waiting for an answer. Since the API is already established, we cannot tell the client "I'm attempting to do what you want, check back later for the answer." The best option we have come up with so far is to add a second, non-rails web server running eventmachine to process these particular calls. Is there a better way?
