• A report writer for non-programmers?

  - by Earlz

  Hello, we are wanting for users to be able to write their own reports in our application. It is a web application. We don't care if they must download an application in order to create reports, but we need for them to be able to print off reports from the web in PDF format or similar. The report writer is to be used by non-programmers, or at best very light programmers(like the ones that make VBA macros and such). (the writer is not a core part of the program though. So if there is a learning curve, then that is acceptable to a certain extent) We were looking at Crystal Reports but it seems like it'll cost $7000 which is just way too much for right now(though our system is very flexible so could support it eventually). We are also looking at Fast Reports which seems pretty promising, but I'm not sure the report writer would be easy for non-programmers to grasp. Can someone recommend a good report writer for non programmers that won't break the bank?

• What is the fastest way to send 100,000 HTTP requests in Python?

  - by Igor G.

  Hello, I am opening a file which has 100,000 url's. I need to send an http request to each url and print the status code. I am using Python 2.6, and so far looked at the many confusing ways Python implements threading/concurrency. I have even looked at the python concurrence library, but cannot figure out how to write this program correctly. Has anyone come across a similar problem? I guess generally I need to know how to perform thousands of tasks in Python as fast as possible - I suppose that means 'concurrently'. Thank you, Igor

• VB FFT - stuck understanding relationship of results to frequency

  - by WaveyDavey

  Trying to understand an fft (Fast Fourier Transform) routine I'm using (stealing)(recycling) Input is an array of 512 data points which are a sample waveform. Test data is generated into this array. fft transforms this array into frequency domain. Trying to understand relationship between freq, period, sample rate and position in fft array. I'll illustrate with examples: ======================================== Sample rate is 1000 samples/s. Generate a set of samples at 10Hz. Input array has peak values at arr(28), arr(128), arr(228) ... period = 100 sample points peak value in fft array is at index 6 (excluding a huge value at 0) ======================================== Sample rate is 8000 samples/s Generate set of samples at 440Hz Input array peak values include arr(7), arr(25), arr(43), arr(61) ... period = 18 sample points peak value in fft array is at index 29 (excluding a huge value at 0) ======================================== How do I relate the index of the peak in the fft array to frequency ?

• What is your motivation?

  - by vava

  As software developers we all know that motivation matters. Without it we could just stare into the monitor all day long and do nothing. There are some tricks to get yourself motivated like talking to people or doing the fun part of the project, but they do not always work. In the mean time I started to notice that I am most productive when I could see the person who is appreciating my work. The user, who is using the software and enjoying it. Because if there's none, what's the point of writing this code? So I was wondering, what makes you be at your top, is it the users, your fellow coders or maybe the money you get? PS. I know there's quite a few questions about motivation but they all about overcoming current situation. What I want to hear is what makes you come to the office every day, what you enjoy the most in your job, what makes you want to write this code and do it as fast as you possible could.

• c# - wmplib - playing 2 mp3 files but can get them in synic

  - by Ciarán

  I have 2 windowsMediaPlayer objects setup Both objects have the same mp3 song file but when I play them at the same time they are out of sync by a few seconds. The code I call to play them looks like this sound1.controls.play(); sound2.controls.play(); Is it just because one play method is executed before the other and thus one fast then the other. Is their anyway I could sync them? I have tired messing with the rate of one track to match the other, but not getting it prefect. Thanks

• Fastest distance lookup given latitude/longitude?

  - by Ryan Detzel

  I currently have just under a million locations in a mysql database all with longitude and latitude information. With this I use another lat/lng to find the distance of certain places in the database but it's not as fast as I want it to be especially with 100+ hits a second. Is there a faster formula or possibly a faster system other than mysql for this? The formula I'm using is this. select name, ( 3959 * acos( cos( radians(42.290763) ) * cos( radians( locations.lat ) ) * cos( radians( locations.lng ) - radians(-71.35368) ) + sin( radians(42.290763) ) * sin( radians( locations.lat ) ) ) ) AS distance from locations where active = 1 HAVING distance < 10 ORDER BY distance;

• How to round CGFloat

  - by Johannes Jensen

  I made this method + (CGFloat) round: (CGFloat)f { int a = f; CGFloat b = a; return b; } It works as expected but it only rounds down. And if it's a negative number it still rounds down. This was just a quick method I made, it isn't very important that it rounds correctly, I just made it to round the camera's x and y values for my game. Is this method okay? Is it fast? Or is there a better solution?

• Multithreading/Parallel Processing in PHP

  - by manyxcxi

  I have a PHP script that will generate a report using PHPExcel from data queried from a MySQL DB. Currently, it is linear in processing in that it gets the data back from MySQL, reads in the Excel template, writes the data to the template, then outputs it. I have optimized the code to the point that the data is only iterated over once, and there is very little processing done on the PHP side. The query returns hundreds of lines in less than .001 seconds, so it is running fast enough. After some timing I have found my bottlenecks to be (surprise, surprise) reading the template and writing the output. I would like to do this: Spawn a thread/process to read the template Spawn a thread/process to fetch the data Return back to parent thread - Parent thread will wait until both are complete Proceed on as normal My main questions are is this possible, is it worth it? If yes to both, how would you tackle it? Also, it is PHP 5 on CentOS

• Logging strategy vs. performance

  - by vtortola

  Hi, I'm developing a web application that has to support lots of simultaneous requests, and I'd like to keep it fast enough. I have now to implement a logging strategy, I'm gonna use log4net, but ... what and how should I log? I mean: How logging impacts in performance? is it possible/recomendable logging using async calls? Is better use a text file or a database? Is it possible to do it conditional? for example, default log to the database, and if it fails, the switch to a text file. What about multithreading? should I care about synchronization when I use log4net? or it's thread safe out of the box? In the requirements appear that the application should cache a couple of things per request, and I'm afraid of the performance impact of that. Cheers.

• Php Framework Advice

  - by gnomixa

  I am looking for a lightweight php framework with the following qualifications: ability to write my own sql queries ( i simply don't trust CakePHP like method where the framework does your sql for you); ability to integrate Jquery easily; built-in templating, or relatively easy to introduce Smarty (or another templating engine) into it; MVC; fast Any advice/comparison? i have looked into CodeIgniter, Symfony and CakePHP so far. Symfony is slow, and CakePHP is too inaccessible ...so far my choice would be CodeIgniter. I played with it a bit, but i would like to hear more experiences. I am looking for a framework that will "enforce" organization of my app in a logical way - MVC seems like a great choice.

• fire and forget compared to http request

  - by cometta

  Hi, i looking for opinion from you all. I have a web application that need to records data into another web application database. I not prefer to use http request GET on 2nd application because of latency issue. I looking for fast way to save records on 2nd application quickly, i came across the idea of "fire and forget" , will JMX suit for this scenario? from my understanding jmx will gurantee message delivery. Let say i need to call at least 1000 random requests per seconds to 2nd application should i use jmx? http request? or xmpp instead?

• Is there any real benefit to using ASP.Net Authentication with ASP.Net MVC?

  - by alchemical

  I've been researching this intensely for the past few days. We're developing an ASP.Net MVC site that needs to support 100,000+ users. We'd like to keep it fast, scalable, and simple. We have our own SQL database tables for user and user_role, etc. We are not using server controls. Given that there are no server controls, and a custom membershipProvider would need to be created, where is there any benefit left to use ASP.Net Auth/Membership? The other alternative would seem to be to create custom code to drop a UniqueID CustomerID in a cookie and authenticate with that. Or, if we're paranoid about sniffers, we could encrypt the cookie as well. Is there any real benefit in this scenario (MVC and customer data is in our own tables) to using the ASP.Net auth/membership framework, or is the fully custom solution a viable route?

• How significant is the bazaar performance factor?

  - by memodda

  I hear all this stuff about bazaar being slower than git. I haven't used too much distributed version control yet, but in Bazaar vs. Git on the bazaar site, they say that most complaints about performance aren't true anymore. Have you found this to be true? Is performance pretty much on par now? I've heard that speed can affect workflow (people are more likely to do good thing X if X is fast). What specific cases does performance currently affect workflow in bazaar vs other systems (especially git), and how? I'm just trying to get at why performance is of particular importance. Usually when I check something in or update it, I expect it to take a little while, but it doesn't matter. I commit/update when I have a second, so it doesn't interfere with my productivity. But then I haven't used DVCS yet, so maybe that has something to do with it?

• Hibernate AssertionFailure in different Threads

  - by bladepit

  I connect to my database with one session. I have always the same session in my hole program. My Thread "1" catches primary data from the database. The user must be allowed to cancel this thread. So if the user presses the cancel button to often or to fast (this is my interpretation) the following error occures: ERROR org.hibernate.AssertionFailure - HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session) org.hibernate.AssertionFailure: possible non-threadsafe access to the session The same errors occures if i cancel my thread "2" which is running in the background after my thread "1" ist finished and the try to load another primary data set from the database. Is the failure that i am using the same session in my two threads? What is the right way to solve such a problem?

• Using CSS Classes for individual effects - opinions?

  - by Cool Hand Luke UK

  Hey, Just trying to canvas some opinions here. I was wondering how people go about adding individual effects to html elements. Take this example: you have three types of h1 titles all the same size but some are black some are gold and some are white. Some have a text-shadow etc. Would you create separate CSS classes and add them do the h1 tag or would you create a new single class for each different h1 title type (with grouped CSS elements)? With singular class for each effect you can build up combos of classes in html class="gold shadow" but also how would you name them. For example its bad practice to give classes and id names associated to colours, because it doesn't define what it does well. However is this ok with textual CSS classes? Just wondering what others do, I know there are no hard and fast rules. Cheers.

• CALayer flickers when drawing a path

  - by Alexey

  I am using a CALayer to display a path via drawLayer:inContext delegate method, which resides in the view controller of the view that the layer belongs to. Each time the user moves their finger on the screen the path is updated and the layer is redrawn. However, the drawing doesn't keep up with the touches: there is always a slight lag in displaying the last two points of the path. It also flickers, but only while displaying the last two-three points again. If I just do the drawing in the view's drawRect, it works fine and the drawing is definitely fast enough. Does anyone know why it behaves like this? I suspect it is something to do with the layer buffering, but I couldn't find any documentation about it.

• custom button MouseLeave event

  - by Jelle

  Hi, I made a custom button with some panels and pictureboxes. With the MouseEnter and MouseLeave I set the appropriate hover images like normal buttons. The problem is that if I move the mouse too fast over the control it sometimes doesn't trigger the MouseLeave event. This way the button is "locked" in hover state. screenshot problem: http://www.jesconsultancy.nl/images/screens/screen_prblm.png the button at the right is locked in "hover" state. How can i solve this? Thanks.

• Elisp performance on Windows and Linux

  - by JasonFruit

  I have the following dead simple elisp functions; the first removes the fill breaks from the current paragraph, and the second loops through the current document applying the first to each paragraph in turn, in effect removing all single line-breaks from the document. It runs fast on my low-spec Puppy Linux box using emacs 22.3 (10 seconds for 600 pages of Thomas Aquinas), but when I go to a powerful Windows XP machine with emacs 21.3, it takes almost an hour to do the same document. What can I do to make it run as well on the Windows machine with emacs 21.3? (defun remove-line-breaks () "Remove line endings in a paragraph." (interactive) (let ((fill-column 90002000)) (fill-paragraph nil))) : (defun remove-all-line-breaks () "Remove all single line-breaks in a document" (interactive) (while (not (= (point) (buffer-end 1))) (remove-line-breaks) (next-line 1))) Forgive my poor elisp; I'm having great fun learning Lisp and starting to use the power of emacs, but I'm new to it yet.

• How safe am I singing into Google Spreadsheets with yeroon.net/ggplot2

  - by Farrel

  I am impressed by what I have seen of yeroon.net/ggplot2 which is a web interface for Hadley Wickham's R package ggplot2. I want to try it out on my own data. The part that has me very excited is that one can use data stored in one's own Google spreadsheet as the data. One just signs into their Google Account so that yeroon.net/ggplot2 can access the spreadsheet list. I have been hesitant to do it. If I sign in whilst on yeroon.net am I handing over my username and password to a third party? It would not be wise of me to divulge my google password to third parties since Google is fast becoming my repository of everything. How do I know if Jeroon's application is using ClientLogin or OAuth? My understanding is very basic and may be wrong but nevertheless here it is. OAuth would be better since it does not actually pass the password onto the third party application.

• Data structure for Settlers of Catan map?

  - by templatetypedef

  Hello all- A while back someone asked me if I knew of a nice way to encode the information for the game Settlers of Catan. This would require storing a hexagonal grid in a way where each hex can have data associated with it. More importantly, though, I would need some way of efficiently looking up vertices and edges on the sides of these hexagons, since that's where all the action is. My question is this: is there a good, simple data structure for storing a hexagonal grid while allowing for fast lookup of hexagons, edges between hexagons, and vertices at the intersections of hexagons? I know that general structures like a winged-edge or quad-edge could do this, but that seems like massive overkill. Thanks!

• Cassandra/HBase or just MySQL: Potential problems doing the next thing

  - by alexeypro

  Say I have "user". It's the key. And I need to keep "user count". I am planning to have record with key "user" and value "0" to "9999+ ;-)" (as many as I'll have). What problems I will drive in if I use Cassandra, HBase or MySQL for that? Say, I have thousand of new updates to this "user" key, where I need to increment the value. Am I in trouble? Locked for writes? Any other way of doing that? Why this is done -- there will be a lot of "user"-like keys. Different other cases. But the idea is the same. Why keep it this way -- because I'll have more reads, so I can always get "counted value" very fast.

• Streaming Flash Video Problem - Clipping

  - by Stanley

  I have a simple flash video player that streams the video from a streaming media server. The stream plays fine and I have no problems with playing the video and doing simple functions. However, my problem is that on a mouse over of the video, I have the controls come up and when I do a seek or scrub on the video, I get little weird boxes that show over the video - like little pockets - of the video playing super fast (you can basically see it seeking) until it gets to the point it needs to be at and then these little boxes disappear. Is anybody else having these problems and if so, how do I fix this? I thought it might be some kind of masking problem, but I haven't been able to figure it out. Please Help!!!

• VS2010 / Code Analysis: Turn off a rule for a project without custom ruleset....

  - by TomTom

  ...any change? The scenario is this: For our company we develop a standard how code should look. This will be the MS full rule set as it looks now. For some specific projects we may want to turn off specific rules. Simply because for a specific project this is a "known exception". Example? CA1026 - while perfectly ok in most cases, there are 1-2 specific libraries we dont want to change those. We also want to avoid having a custom rule set. OTOH putting in a suppress attribute on every occurance gets pretty convoluted pretty fast. Any way to turn off a code analysis warning for a complete assembly without a custom rule set? We rather have that in a specific file (GlobalSuppressions.cs) than in a rule set for maintenance reasons, and to be more explicit ;)

• What's the best JSF implementation?

  - by Jeff

  Hey everyone, I currently have a medium size Java web application sitting on top of Spring MVC. As much as I like (no sarcasm) coding straight HTML, CSS and JS, it's not possible for me to develop as fast as I'd like. I'm looking at different RAD frameworks to speed up my development. I'm looking at JSF implementations and component libraries, Flex, GWT and a few others. As of now, Apache MyFaces (with ICEFaces) seems to be the front runner in my mind, but I'm curious to find out what you all think of that specific implementation and if the Sun implementation is any better? What's important to me is something that is stable, has an active community and that it doesn't look like there is another technology in the near future that is going to eclipse JSF (which would drive me to use a different RAD framework). Thanks in advance for the responses.

• Java - sorted stack

  - by msr

  Hello, I need a sorted stack. I mean, the element removed from the stack must be the one with great priority. Stack dimension varies a lot (becomes bigger very fast). I need also to search elements in that stack. Does Java give some good implementation for this? What class or algorithm do you suggest for this? I'm using a PriorityQueue right now which I consider reasonable except for searching, so Im wondering if I can use something better. Thanks in advance!
