  • Good podcasting solution?

    - by burnso
    I simply ask for the best, most common and simple way to set up a podcast? Please, I need an answer so I can close this question? I run a joomla-based website for a small church and now need a simple, cheap and effective solution for an audio podcast. I am looking for a solution that will do the following: User uploads audio files to service (preferably not to our own site) that is cheap, fast and simple to use. Dropbox for example? Files are easily embeddable into Joomla website articles to be played on the spot (through simple-to-use and media player). Preferably through RSS feeds (to make it easy to update every week). Files are downloadable. Files are viewable on iPhones and other smartphones. Solution can be broadcasted via iTunes. Solution doesn't need a lot of extra, new third party software. I'd rather keep it simple and familiar than have it be a complete new system but with a steep learning curve. At the moment we use vimeo to host the podcast, through video files. But we'd like to move to something simpler that doesn't involve a series of difficult steps to upload the files to the web.

  • How to ask developers to think about high resolution screens

    - by WhiteWind
    I just got a ASUS N56VZ laptop, and it`s all good, but the screen resolution 1920x1080px. I am not asking, how to scale ui elements. If someone is interested I have found some tricks: increase font size in system settings increase unity dock size in MyUnity or system settings in modern Ubuntu versions. tweak userChrome.js of FireFox to make buttons|panels|icons larger add DefaultZoomLevel extension to FireFox to make it zoom pages initially. But all of it is miserable, because there are some big bugs: window decoration elements are way too small to pick them with mouse. I can't scale window easily and I can't position my cursor fast on the close|maximize buttons. Tuning lines like in sound volume dialog are hardly clickable at all. Unity top panel (status panel & tray) hardly can contain the bigger font, so it looks ugly, but icons are still the same. Sometimes I can`t read text, as it is cropped (and I cant scale some dialogs as it has fixed size) Chromium is not usable at all (ok, it's not Ubuntu problem, but the problem still exists) JAVA applications are not scalable (same as above) In FF I am able to get descent results in most cases, but multiplication of system font increase and browser font increase makes system controls (combobox, lists, drop down lists) extremely big, so I cant even control the zoom level on the page. IMHO, we should post a bug report (but what kind of bug?) and vote for it! The problem is even deeper, but at least we should ask developers to think about it. So my question is: how can I post a report (the right words and right place) and how can we (who already has that problem, or who want it to be solved before hardware upgrade) vote for faster solution. Any ideas?

  • Should I build a multi-threaded system that handles events from a game and sorts them, independently, into different threads based on priority?

    - by JonathonG
    Can I build a multi-threaded system that handles events from a game and sorts them, independently, into different threads based on priority, and is it a good idea? Here's more info: I am about to begin work on porting a mid-sized game from Flash/AS3 to Java so that I can continue development with multi-threading capabilities. Here's a small bit of background about the game: The game contains numerous asynchronous activities, such as "world updating" (the game environment is constantly changing based on a set of natural laws and forces), procedural generation of terrain, NPCs, quests, items, etc., and on top of that, the effects of all of the player's interactions with his environment are programmatically calculated in real time, based on a set of constantly changing "stats" and once again, natural laws and forces. All of these things going on at once, in an asynchronous manner, seem to lend themselves to multi-threading very well. My question is: Can I build some kind of central engine that handles the "stacking" of all of these events as they are triggered, and dynamically sorts them out amongst the available threads, and would it be a good idea? As an example: Essentially, every time something happens (IE, a magic missile being generated by a spell, or a bunch of plants need to grow to their next stage), instead of just processing that task right then and adding the new object(s) to a list of managed objects, send a reference to that event to a core "event handler" that throws it into a stack of all other currently queued events, which then sorts them out and orders them according to urgency, splits them between a number of available threads for as-fast-as-possible multithreaded execution.

  • Whats a good host for an active vBulletin site?

    - by Kyle
    I've been switching hosts using a VPS each time and I'm just really not sure I'm finding the right VPS's. I've used a VPS from burst.net & rubyringtech and I just feel like it's slowly killing my site because of the slow speed. I really don't know if it's the network or the VPS itself but I really wish to fix this. When I TOP into the VPS peak times it shows this: top - 03:18:56 up 16:33, 1 user, load average: 1.33, 1.40, 1.33 Tasks: 30 total, 1 running, 29 sleeping, 0 stopped, 0 zombie Cpu(s): 27.2%us, 13.6%sy, 0.0%ni, 59.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1048576k total, 679712k used, 368864k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached And pages take atleast a good 2-3 minutes to load. I have only like 50-60 members on the forum also. I had a shared hosting account and the forum was lightning fast.... Is a VPS a bad idea? :\ What should I do to fix this? I'm running lighttpd with xcache, and the latest mysql + php version. The server is a intel i7 2600 w/ 1gb uplink (I think the 1gb uplink is a lie because I've tested the network and the highest download speed I've seen was 20mb/s from a code.google page) All in all I've seen people talking about linode. Should I try them? I honestly don't need a dedicated server yet it's only 50-70 members online. What should I do? I really want a VPS because I enjoy root access. Does anyone have any suggestions?

  • Cheap ways to do scaling ops in shader?

    - by Nick Wiggill
    I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

  • Client/Server game even in solo: any big problem?

    - by Klaim
    I'm making a game which have strong basic design based on multiplayer but also should provide a really interesting and self-sufficient solo game. A bit like a real-time strategy game. The events and actions taken shouldn't be as massive and immediate as in a FPS, so you can also think the networking like for an RTS. It's a PC game, targetting Windows, MacOSX and Linux (Ubuntu & Fedora). It's programmed in C++, using a variety of open source libraries, so I have great (potential) control over the performances. So far I always considered that just making the game work with two applications, client & server, even in solo mode was ok. However, as I'm in the process of starting the network code I'm having doubts about if it's a good idea. I'm not a specialist so I might be missing something in my analysis. I see these pros and cons: Pros: The game works only one way so if I fix a bug it should apply on all game modes, whatever the distance with the server is; Basic networking issues would be detected early, including behaviour with the protection softwares (firewall) installed (i am not specialist so this might be wrong); Cons: I suppose that even if it should be really fast enough, networking client and server on the same computer would still be slower than no networking and message passing in (one) process memory. Maybe debugging would be more difficult? I don't have experience in this case but so far I assume that debugging with Visual Studio allows me to debug multiple process so it shouldn't be really different. Also, remote debugging. My question is: is there a big disadvantage that I missed? Or maybe there are advantages that I missed and that should encourage me to just continue with only client-server game sessions?

  • What is the recommended MongoDB schema for this quiz-engine scenario?

    - by hughesdan
    I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

  • Need Directions to become a programmer [closed]

    - by Omin
    Before youguys go on about how there are many types of programmers, please read through the post. Long term goal: Develop my own software (company) Short term goal: Get a job that involves coding/programming Current status: Support Analyst (at a software company but does not involve any programming) with 40k salary, 3rd year computer engineering student I had everything figured out. I'm going to develop a 2D scrolling game for iphone or android, publish the app, sell a bunch, and then apply at a studios as a software developer. And then something hit me. I think I need to get a job that involes programming to learn as much as I can in the shortest time possible. So I got a phone interview at a fast growing start up software company, passed that no problem, but then had to take an online technical assessment. That failed miserably. I thought that if I could just present myself, show that I am hard working, positive attitude, eager to make self improvements, type of a guy, I could get the job. I was wrong. And now, I am lost. Im thinking of staying with my job until I find a new one as a programmer. I will be working, self studying, and trying to make this happen without finishing university. I forgot to mention that the online technical assessment was based on data structures/algorithms, OO design, runtime complexity. I was hoping that I could get some guidence. Should I be focusing on app development or study computer science fundamentals? I have a list of books I can be going through: Learning C# O'Reilly (I got interested in C# because of Unity3D and Mono), C# 5.0 in a Nutshell, Head First Design Patterns, Code Complete, Introduction to Algorithms, Programming Interviews Exposed, Cracking the Coding Interview, The Google Resume.

  • Login Screen hangs after entering password

    - by Ravi
    When I enter my password in the login box nothing happens. It gets stuck. It was running fine earlier. I have installed gnome-panel and cairo-dock, after which, I logged out, logged back in, and choose gnome classic session. I also added a ppa from the webupd8.org to install the themes (link). I opened Ubuntu Tweak tool, and changed the theme to Evolve the whole laptop stopped responding. The keyboard and mouse were unresponsive. So I was forced to do a shut down. Now whenever it starts, I cannot login into Ubuntu. I hear the fan noise, as its spinning very fast, when the laptop freezes.(Probably the CPU is running at 100%). Please help me. How can I login back to Ubuntu? I am using Ubuntu 12.04 and have installed all the latest updates.. EDIT: I want to know how can I delete a folder from the file system using the live CD?

  • Tuning WebServer Response -

    - by Vedran Wex Maricevic
    I have this sam e question on StackOverflow and I was advised to ask it here hoping for more information. Here is the question: I am in rather unfavorable situation. I have aspdotneststore front e-commerce application and search addon called VibeTrib. I dont have source code for both of those. Store that runs on StoreFront and VibeTrib has close to 250k products. Also we have lots of filters. I spoke to ViTrib reps, and they want extra money so they could optimize Queries that they use. Money they require is nto a big deal, but the problem is I dont trust them anymore. What we got is much different then wha is being advertised. To cut the long story short. I am runing the store on Amazon AWS now, and regardless of what DB (MsSQL 2012) server I set (I tried 32GB RAM monsters instances) it is slow. Ajax search uses Full Text search and it displays search keywords relatively fast, but once the search is performed ( to display all results) it is still slow.!!! There is something that I could to do accelerate the speed on my own end? I do have full control over EC2 Instance (Web server Server 2012 and IIS 8). Can I set IIS to step in for the search and cache some of it? I was hoping to cache at least some most common words. My best bet is IIS 8 :) Is there any help in my case? Thanks

  • IE 9:Release

    - by xamlnotes
    Yippie: IE 9s coming out March 14!: http://windowsteamblog.com/ie/b/ie/archive/2011/03/09/a-more-beautiful-web-launches-on-march-14th.aspx For you guys that love other browsers that’s ok. Personally I love IE for many reasons such as ease of use and stability.  I am cranked up to see what IE 9 does as it was retooled from the start. So this one should be big. Also, its bringing HTML 5 support now so we can have much richer applications. Its about time that HTML was revved to move from the old text like stuff to a better model. More info: http://windowsteamblog.com/ie/b/ie/archive/tags/ie9/ Some glimpses here: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features and http://www.beautyoftheweb.com/#/highlights/all-around-fast   Looks like it will be much faster (with hardware support now) in many areas.  Better startup times and install times are hot on my list of favorites too. Plus they retooled the UI in many places too.  The UI looks a lot cleaner now: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features/focused-on-your-websites Plus theres tons more like changes in tab pages, a notfication bar, pinned sites and so forth. Plus theres cool integration with Windows 7 also.

  • Content light website and Google - Tell google it's a listings site (as opposed shop, reviews or restaurants)

    - by Doug Firr
    I have a listings style website. Due to the nature of this (listings) the site is content light. Each page is typically less that 50 words but there are many pages. The site in question has had a ton of media coverage and so has some great inbound links from places like Wired, Fast Company, Canada Broadcasting Corporation and many many other bloggers, media websites and recycle related niche authors (It's a recycling site). But Google really ignores it. Traffic from search is very very low - less than 5% of all traffic. I know that using markup you can tell Google whether your site is a restaurant, article, review, shop, local business and a few other categories (https://www.google.com/webmasters/markup-helper/u/0/). Is there a way to tell Google that my site is a listings site? I suspect, but do not know for sure, that part of the problem is that Google simply does not know what my site is? It's a crowdmap where people post curbalerts. The information is useful to people but it is presented in a short, concise way - a pin on a map, a picture and a short description. Adding anything further is not necessary for the site's intended purpose. 1st question - how best to tell the search engines what y site is - listings and not some spammy website? Any recommendations in improving our site's Search presence? You can take a look here if interested: http://tinyurl.com/lxg4hn7

  • Using Bullet physics engine to find the moment of object contact before penetration

    - by MooMoo
    I would like to use Bullet Physics engine to simulate the objects in 3D world. One of the objects in the world will move using the position from 3D mouse control. I will call it "Mouse Object" and any object in the world as "Object A" I define the time before "mouse object" and "Object A" collide as t-1 The time "mouse object" penetrate "Object A" as t Now there is a problem about rendering the scene because when I move the mouse very fast, "Mouse object" will reside in "Object A" before "Object A" start to move. I would like the "Mouse Object" to stop right away attach to the "Object A". Also If the "Object A" move, the "Mouse object" should move following (attach) the "Object A" without stop at the first collision take place. This is what i did I find the position of the "Mouse Object" at time t-1 and time t. I will name it as pos(t-1) and pos(t) The contact time will be sometime between t-1 to t, which the time of contact I name it as t_contact, therefore the contact position (without penetration) between "Mouse object" and "Object A" will be pos(t_contact) then I create multiple "Mouse object"s using this equation pos[n] = pos(t-1) * C * ( pos(t) - pos(t-1) ) where 0 <= C <= 1 if I choose C = 0.1, 0.2, 0.3,0.4..... 1.0, I will get pos[n] for 10 values Then I test collision for all of these 10 "Mouse Objects" and choose the one that seperate between "no collision" and "collision". I feel this method is super non-efficient. I am not sure the way other people find the time-of-contact or the position-of-contact when "Object A" can move.

  • error while trying to resize the partition

  • Oracle Virtual Desktop Infrastructure

    - by Fat Bloke
    A lot of the recent blog entries here have been about Oracle VM VirtualBox, possibly the coolest personal desktop virtualization product known to man. Deploying VirtualBox on your PC or Mac lets you run many virtual desktops at the same time to one user, you. But did you know that VirtualBox can also power an Enterprise-scale virtual desktop deployment too, delivering many desktops to many users?  As part of another Oracle product, Oracle Virtual Desktop Infrastructure (VDI), VirtualBox can run your Windows, Linux or Solaris desktops on servers located in the datacenter. Oracle VDI orchestrates the whole deal by looking after : creating or cloning the virtual desktops from a master template; managing the lifecycle of the desktops (create, start, suspend, resume, stop, delete); assigning which users get which desktops;  delivering easy and fast access to these virtual desktops from almost any device, such as existing PCs or Macs, iPads, or specially designed Sun Ray client devices too; load balancing and session management of all of this.  Architecturally the solution looks something like this: This is an increasingly hot area of the IT landscape, so the Fat Bloke has decided to create a new blog category (VDI) and dedicate a few blog entries to look into this in a bit more detail over the next few weeks. Watch this space... - FB

  • What is the simplest way for a slippy SVG visualization?

    - by totymedli
    I have a big SVG file representing a complicated graph with hundreds of points. I want to represent this in a web page. My idea was that I could make it like Google Maps represent their maps, in those slippy, dragable, moveable maps. I'am looking for an easy and fast JavaScript library which could do the work. What I need for my "map" is the drag/move, zoom ability, and some way to click on the points of the picture, which makes a little information apear about that point, like Google maps markers. I'am looking for a free/open source library. I saw some solutions but I'am uncertain about them, and none of them seemed to be perfet: Polymaps - I love the technique it uses, but I don't know much about this library. Leaflet - I love the simplicity of it, but I dont know how could I apply it for my SVG. Raphael - I heard the awesomeness of this, but It seemed a lots of work to do this task. What would be the best/easiest solution for my problem, and what is your opinion aboute the above libraries?

  • Drive reporting incorrect free space

    - by Oli
    So I swapped my shiny SATA SSD for an even shinier PCI-E SSD. I run my core OS on the SSD because it's silly-fast. I did this on my old SSD so I created a new EXT4 partition and then just dded the data across (sorry I don't know the exact command I ran anymore) and after reinstalling grub, I booted onto the PCI-E SSD. At first glance everything had worked perfectly and things were running faster than ever. But then I noticed the free disk space on the new, larger drive: it was almost exactly the same as it was on the other disk... A disk that was half its size. So it looks as if I've copied the files across incorrectly and it's copied some of the filesystem metadata along with it. Tools like du and Disk Usage Analyzer come back with the correct figures. Things that look at the partition (and not the files) seem to think the drive is 120GB I've been using this drive for a week now so it's way out of sync with the old SSD so dumping the data and starting again isn't a job that fills me with joy but two questions: Is there a way to fix my filesystem so it knows what it's really on about? fsck e2fsck and badblocks all seem to be able to scan it without finding a problem with it. If I do plug my old SSD back in, copy the data off my PCI-E on to it and then copy it back onto a fresh filesystem (eg juggle the data around), what's the best way of doing that? I obviously want to keep all the permissions and softlinks where they are.

  • How do I add a boot from cd option to yaboot?

    - by Sergiu
    So I'm dual-booting Ubuntu 12.04.1 on my iMac G5 powepc alongside Mac OS X and I want to add a boot cd option to yaboot because I'm trying to boot a scratched Mac OS X installation DVD that takes a while to read and the frst bootstrap moves on too fast. How do I edit the timeout for the first bootstrap anyways? So, my main question is, how do I add a cd booting option to yaboot and then, how doI boot it? The devalias from OpenFrmware tells me that 1 have 2 cd-rom instaled, on is /ht/pci@3/ata-6/disk@0 and the other on ends with a 1 instead of a zero. These are the contents of my yaboot.conf file: yaboot.conf generated by the Ubuntu installer run: "man yaboot.conf" for details. Do not make changes until you have!! see also: /usr/share/doc/yaboot/examples for example configurations. For a dual-boot menu, add one or more of: bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ boot="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part2" device=/ht@0,f2000000/pci@3/k2-sata-root@c/@0/@0 partition=4 root="UUID=798a048f-ee48-49e0-bba3-111aed8dee04" timeout=12000 install=/usr/lib/yaboot/yaboot magicboot=/usr/lib/yaboot/ofboot enablecdboot macosx="/dev/disk/by-id/scsi-SATA_ST3160023AS_5MT1GCWA-part3" image=/boot/vmlinux label=Linux read-only initrd=/boot/initrd.img append="quiet splash" What do I add here so that yaboot will boot from my cd in like 3 minutes after startup? Thanks!

  • New Workstation &ndash; Lenovo W530 Core i7 32GB 256GB SSD Win8Pro

    - by Brian Lanham
    So I pretty-much have my new machine up and running full-time. I am still going to have to hit my old workstation for some things but am more-or-less working on my new machine.  It’s really fast. And Bret was right, I’m not so far using all the RAM. 16 would have been enough but as @CodeMonkeyJava “go big or go home”. Windows 8 is…interesting.  So far I still seem to do most of my work in the “Desktop”.  However, I like the Store concept and I like the Metro UX.  Live tiles are also nice.  I really like how I can switch between Desktop and Metro easily.  Overall I think Microsoft has done a great job of combining the needed experience for touch and mouse. My overall Windows 8 rating is 5.9 because of the video card. Otherwise I’m hitting 7.8.  The system boots from cold in about 11 seconds and performs complete shutdown in 4.7 seconds.  It wakes from sleep in less than 1 second. VS 2012 starts and restarts almost instantly.  In fact, I find myself staring at the start page without realizing it.  Build time doesn’t seem to be significantly increased but it is faster. I seem to already be reinvigorated for work with this new machine. I’m looking forward to the performance.
