• View matrix in opengl

  - by user5584

  Hi! Sorry for my clumsy question. But I don't know where I am wrong at creating view matrix. I have the following code: createMatrix(vec4f(xAxis.x, xAxis.y, xAxis.z, dot(xAxis,eye)), vec4f( yAxis.x_, yAxis.y_, yAxis.z_, dot(yAxis,eye)), vec4f(-zAxis.x_, -zAxis.y_, -zAxis.z_, -dot(zAxis,eye)), vec4f(0, 0, 0, 1)); //column1, column2,... I have tried to transpose it, but with no success. I have also tried to use gluLookAt(...) with success. At the reference page, I watched the remarks about the to-be-created matrix, and it seems the same as mine. Where I am wrong?

• Web development starting a career [closed]

  - by user985482

  Hi I am in the 3rd and last year at college of informatics and I am interested to follow a career in web development when I finish(2 more months). From what I understand this days to get hired you need to be able to know a variety of technologies at least that is the case in Romania.Most of the jobs I have seen even at entry level asks you to know the following: HTML/CSS Javascript , a framework preferable jQuery , Ajax a server side language in my case PHP and a framework SQL and an RDBMS in my case MySql a CMS in my case Wordpress My question is how well should me or anyone looking to get hired as a web developer for there first job should we know this technologies in order to get hired and what else should we aim to learn to have a better chance of getting hired. I don't know if the question is right for this forum but I believe that this could help many of the students and anyone who is taking an interest in web development to know what they should expect from there employers when they try to find work.

• Prologue…

  - by Chris Stewart

  Hi all,                 This is the beginning of my blog. I have been a software developer for going on 11 years using the Microsoft toolset (primarily VB 5, VB 6, VB.net and SQL Server 6, 7, 2000, 2005, 2008). My coding interests are C#, ASP.net, SQL and XNA. Here I will post my musings, things of interest, techie babble and sometimes random gibberish. My hope for this blog is to document my learning experiences with C#, help, encourage and in some way be useful to those who come after me. Thanks for reading!

• Improving performance of fuzzy string matching against a dictionary [closed]

  - by Nathan Harmston

  Hi, So I'm currently working for with using SecondString for fuzzy string matching, where I have a large dictionary to compare to (with each entry in the dictionary has an associated non-unique identifier). I am currently using a hashMap to store this dictionary. When I want to do fuzzy string matching, I first check to see if the string is in the hashMap and then I iterate through all of the other potential keys, calculating the string similarity and storing the k,v pair/s with the highest similarity. Depending on which dictionary I am using this can take a long time ( 12330 - 1800035 entries ). Is there any way to speed this up or make it faster? I am currently writing a memoization function/table as a way of speeding this up, but can anyone else think of a better way to improve the speed of this? Maybe a different structure or something else I'm missing. Many thanks in advance, Nathan

  - by nkint

  hi i'm getting started with glsl with quartz composer. i have a patch with a particle system in which each particle is mapped into a sphere with a blend value. with blend=0 particles are in random positions, blend=1 particles are in the sphere. the code is here: vec3 sphere(vec2 domain) { vec3 range; range.x = radius * cos(domain.y) * sin(domain.x); range.y = radius * sin(domain.y) * sin(domain.x); range.z = radius * cos(domain.x); return range; } // in main: normal = sphere(p0); * blend + gl_Normal * (1.0 - blend); i'd like the particle to be on a cube if blend=0 i've tried to find but i can't figure out some parametric equation for the cube. mayebe it is not the right way?

• UK Connected Systems User Group - Udi Dahan Event Topic change

  - by Michael Stephenson

  Hi Just wanted to get the word out about a change to the may user group event.  Udi Dahan will present a new topic which he has not presented in the UK before.  Details below. To register for this event please refer to: http://ukconnectedsystemsusergroup.org/UpcomingEvents.aspx Title: High Availability - A Contrarian View   Abstract: Many developers are aware of the importance of high availability, critically analyzing any single points of failure in the infrastructure. Those same developers rarely give a second thought to the periods of time when a system is being upgraded. Even if all the servers are running, most systems cannot function in-between versions. Yet with the increased pace of business, users are demanding ever more frequent releases. The poor maintenance programmers and system administrators are left holding the bag long after the architecture that sealed their fate was formulated. Join Udi for some different perspectives on high availability - architecture and methodology for the real world.

• Free Web hosting for web applications

  - by Jairo

  Hi! Are there web sites that offers hosting of a web application that uses c++? I know that there are a lot of free web hosting solutions that offers hosting for regular web applications made with php, mysql, etc. I would like to upload a routing engine for my website. My application is a travel planner, and I have a custom routing engine that is made of c++. If there are free online Linux OS hosting that can act as a ordinary OS installation (which will be my best option), I would greatly appreciate if you can list them below. Thanks in advance.

• What would be a best way to code a rudimentary LIMS?

  - by Sam

  Hi, I hope that I am asking the right question at right place. If not, please do not hesitate to point me to the right place. I am working in a laboratory, where computers/programming/programmers are all used only as support. But I believe that we need better information organization and management. Given the diverse information generated in the lab I believe that we need some sort of Laboratory Information Management System. Is there a good starting point to do this? I am myself not a trained programmer. I can code reasonably well in python and R, and if necessary I can learn MySql, php.

• Print to File in Black and White (not in greyscale)

  - by user2413

  Hi all, I have these pdf files of c++code and they are colored which would be cool, except that the network printer here is b&w and the printed out codes come in various shades of pale grey which makes them essentially unreadable (specially the comments). I would like everything (text, codes, commands,...) to be printed in the same (black) color. i've tried fuddling with the printer's properties, but the closest thing i see is the 'level of grey' tab, and there i have the choice between 'enhanced' and 'normal' (and it doesn't make a difference in my case). i've tried 'print to file', but i don't see any options there to print to b&w, I've tried installing the 'generic cups printer', but again no options to print to b&w. any idea ? (i'm on 10.10)

• Deluge bit torrent. No incoming connections?

  - by mark kirby

  Hi I keep getting a no incoming connections on my Deluge. I know this is a pretty common problem from Google, but I have posted here to see if any one knows why this happens. I have port forwarded my router and set Deluge to the correct port range. Is this just a bug ? It does not seem to affect the speed so I obviously do have incoming connections and Transmission says the ports are open. So I guess my question is why is this happening ?

• How to check the information of current installed video drivers on Ubuntu?

  - by smwikipedia

  Hi guys, I have just installed Ubuntu 10.04. My CPU usage is high when I do trivial things such as scrolling through a PDF file. So I think my video driver is not properly installed. I want to confirm that by checking the information of my currently installed video driver, such as if there's a driver installed and what version it is. Then I could decide whether to install a new one if it is not up to date. On Windows, I could use the device manager, how to do that on Ubuntu Linux? I don't expect a GUI solution for this. Command line will be just good enough. Many thanks.

• Any idea for a master thesis in software engineering

  - by medusa

  Hi! I have to choose a thesis for my master degree. Time is limited to about 6 months. Do you have any idea? Any personal thesis that was successful? After searching around for some time now, i see the most famous topics are related to artificial intelligence, but i don't want something like that, because most of it would be just theory and boring. A lot of students present these kind of studies because those are the most difficult. I would prefer something that does not necessary include that mathematical complexity but which is an everyday-life topic, and gives concrete ideas, hypothesis, or solutions to some actual problems. Hope i gave my whole idea: i am looking for something that is different from the majority of what all students do, and able to impress the audience... :) I would really really appreciate any your suggestion, Thank you!

• Embed audio broadcasting on web page

  - by giargo

  Hi, I'd like to embed simple audio player on my webpage and I want it to get the audio from a stream broadcasted from my server. I read I can use IceCast on my web-server, getting an audio stream from a client using IceS (or this is what i got from other questions and articles) but once I have my stream, IceCast is supposed to broadcast it on an URL, that can be opened from pkayers like winamp or similar. I've found out this is quite a rare topic, usually people just want to broadcast "radio" where files are taken from a static playlist. In this case I have to get a stream from an IceCast URL and embed it with a player on a web page. Thank.

• Magento Checkout options

  - by graham barnes

  Hi I want to add some options to my magento, lets say i print on clothing, a customer buys some t-shirts, shirts and jackets from me, it totals to £60+ VAT on the checkout area where i signup and not before I need to add an option where I can add a text box and upload option, can i do this? I ideally then want to add some pricing options if the user has chosen to add some branding to a product or multiple products e.g. if the branding was on the top right of the shirt it will cost £5.00, if on the back it costs £7.00 etc all if possible to be done via the admincp. I also want an option so when they upload their logo for the first time they are charged a one off charge, like a setup fee but If the customer has allready sent in there logo then no charge applies. thanks Graham

• Tiled game: how to correct load background image ?

  - by stighy

  Hi, i'm a newbie. I'm trying to develop a 2d game (top-down view). I would like to load a standard background, a textured ground... My "world" is big, for example 3000px X 3000px. I think it is not a good idea to load a 3000px x 3000px image and move it... So, how is the best practice ? To load a single small image (64x64) and repeat it for N times ? If yes, ok, but how i can manage the "background" movement ? Thanks Bye!

• wrestling with some rewrites for Apache...

  - by Evert

  Hi all, I have upgraded my gallery2 to gallery3, and notice that some links no longer resolve correctly. Since the proper way is to redirect these with a 301, that is the way I'm going. The following series need redirecting: folders: old: http://photo.meulie.net/v/various/Gry/ new: http://photo.meulie.net/various/Gry/ pages: old: http://photo.meulie.net/v/Jacob/02112008310.jpg.html new: http://photo.meulie.net/Jacob/02112008310 (both are of course just examples. there are 100's of folders & files to redirect...) I think there were/are also direct links to images, but those I'm not bothering with for now. Who can help me out? :-) Regards, Evert

• SQL SERVER – Convert Seconds to Hour : Minute : Seconds Format

  - by Pinal Dave

  Here is another question I received via email. “Hi Pinal, I have a unique requirement. We measure time spent on any webpage in measure of seconds. I recently have to build a report over it and I did few summations based on group of web pages. Now my manager wants to convert the time, which is in seconds to the format Hour : Minute : Seconds. I researched online and found a solution on stackoverflow for converting seconds to the Minute : Seconds but could not find a solution for Hour : Minute : Seconds. Would you please help?” Of course the logic is very simple. Here is the script for your need. DECLARE @TimeinSecond INT SET @TimeinSecond = 86399 -- Change the seconds SELECT RIGHT('0' + CAST(@TimeinSecond / 3600 AS VARCHAR),2) + ':' + RIGHT('0' + CAST((@TimeinSecond / 60) % 60 AS VARCHAR),2)  + ':' + RIGHT('0' + CAST(@TimeinSecond % 60 AS VARCHAR),2) Here is the screenshot of the resolution: Reference: Pinal Dave (http://blog.SQLAuthority.com)Filed under: PostADay, SQL, SQL Authority, SQL DateTime, SQL Query, SQL Server, SQL Tips and Tricks, T SQL
