  • Conscience and unconscience from an AI/Robotics POV

    - by Tim Huffam
    Just pondering the workings of the human mind - from an AI/robotics point of view (either of which I know little about)..   If conscience is when you're thinking about it (processing it in realtime)... and unconscience is when you're not thinking about it (eg it's autonomous behaviour)..  would it be fair to say then, that:   - conscience is software   - unconscience is hardware   Considering that human learning is attributed to the number of neural connections made - and repetition is the key - the more the connections, the better one understands the subject - until it becomes a 'known'.   Therefore could this be likened to forming hard connections?  Eg maybe learning would progress from an MCU to FPGA's - therefore offloading realtime process to the hardware (FPGA or some such device)? t

  • is there a bug with restart in edubuntu 12.04

    - by Ket
    After a clean install of edubuntu 12.04 on an Acer AO531-h netbook, restart doesn't work. The process starts normally but just before it shuts down the netbook freezes and I have to force shut down. The command "sudo reboot" has the same problem. I have no issues with shut down, only with restart. I'm absolute beginner. Netbook specs: Acer, intel atom CPU N270 @1.60GHz, 1.05 GHz 0.98GB RAM Dual booting with windows xp. No problems with windows.

  • AndEngine Sprite position

    - by Kirill Kulakov
    I had noticed the AndEngine a few days ago, and I tried to create basic game with a few Sprites.Sure, the engine makes the development process much more easier.However I found the sprite lacking a major functionally: Whenever there is a need to refer to the position of an Sprite the engine manipulates the position based on the top-left corner of sprite,this is not the best thing because there is a need to subtract/add the width/height to its position in order to refer to its center.However when we refer to he scale of the Sprite it scaled according to its center point (which is great) I find it very confusing to refer to its position each time differently.I solved that by extending the Sprite class and implementing my methods of setCenter and getCenter, I guess that not the best way to do so. Do you have any suggestion?

  • Asus Eee PC 701 4G hangs on boot

    - by Andrew
    I've got an old Eee PC 701 4G with the following specifications: 512 MB RAM 4GB SSD drive SM223AC 8GB SD card extension Screen resolution: 800 x 480 BIOS Revision 1101 (05/16/2008) EC Firmware version: EPC-079 Windows XP SP3 works fine on it, but I decided to switch my OS to Ubuntu. I have downloaded an Ubuntu 10.10 Netbook Remix ISO and wrote it to my FAT32 SD card using Universal-USB-Installer-1.8.3.3, as described on ubuntu.com During standard load from the SD card the boot process hangs up with black screen. If I'll press F6 while preloading Ubuntu, it sucessfully displays the boot menu, selecting language and showing 2 main commands: "Run ubuntu from USB drive" and "Install Ubuntu". Selecting either of these commands leading to the same result - after some background work the main loading indicator is displayed ("Ubuntu" text with dotted progress bar under it), and it's progressing forever without any effect. Is Ubuntu 10.10 compatible with my Eee PC at all? How to boot it correctly?

  • Software Productivity Tools-&gt; The Missing Link?

    In an op-ed piece in this months SD Times, I make the argument that software development productivity tools have evolved over the years to become more mainstream. I make the case that while some developers shun tools, in reality they take for granted the tools they are using today that were not available 10 years or so ago, or were not that mature. For example today we use some tools without even thinking such as: SCM, build management, standards enforcement, ORM and UI components. Tools today save a team a tremendous amount of time and are the missing link in the software development process. You can get the March issue of SD Times on the newsstands today or read my article online here.

  • What is the practical use of IBOs / degenerate vertex in OpenGL?

    - by 0xFAIL
    Vertices in 3D models CAN get cut in the process of optimizing 3D geometry, (degenerate vertices) by 3D graphics software (Blender, ...) when exporting because they aren't needed when reusing a vertex for multiple triangles. (In the current case 3D data is exported from Blender as .ply and read by a simple application that displays the 3D model) Every vertex has a few attributes like position, color, normal, tangent,... But the data for each vertex that is cut through the vertex sharing is lost and is missing in the vertex shader. Modern shader techniques like Bump or Normal mapping require normals/tangents per vertex which are also cut. To use complex shader techniques IBOs must not be used? Or is there a way to use IBOs and retain the data per vertex that was origionally lost?

  • Ubuntu 12.04 boot freezes

    - by Lajos Soukup
    I installed win7 on one of my machines. It works without any problem. Now I can not install Ubuntu 12.04 (11.10, 11.04) because the installation process stops in a very early stage: I can see that ISOLinux was loaded, then I can see some very simple icons, then I can see text messages of the kernel. The last message I can see: [6.177983] sr 5:0:0:0: attached scsi general ss1 type 5 At that point the system stops. I tried different versions (11.04) , I disabled, and then disconnected the hdd, but the same problem occured independently from my actions. I can boot a gparted live cd, but that system can not see my hdd. On the other hand, I can boot the installation cd of the latest stable Debian distribution without any problem, but I would prefer to use Ubuntu, because I use that distribution on all of our machines.s Configuration: Asus P8H61-MLE motheboard, Gigabyte GTS 450, Intel i5, 4gb ram, wd 1T sata hdd Any idea? Best regards, Lajos

  • Best practice Java - String array constant and indexing it

    - by Pramod
    For string constants its usual to use a class with final String values. But whats the best practice for storing string array. I want to store different categories in a constant array and everytime a category has been selected, I want to know which category it belongs to and process based on that. Addition : To make it more clear, I have a categories A,B,C,D,E which is a constant array. Whenever a user clicks one of the items(button will have those texts) I should know which item was clicked and do processing on that. I can define an enum(say cat) and everytime do if clickedItem == cat.A .... else if clickedItem = cat.B .... else if .... or even register listeners for each item seperately. But I wanted to know the best practice for doing handling these kind of problems.

    - by Soumya Simanta
    I want to create to deploy a heartbeat service (a python script) as a service using Upstart. My understanding is that I've to add a /etc/init/myheartbeatservice.conf with the following contents. # my heartbeat service description "Heartbeat monitor" start on startup stop on shutdown script exec /path/to/my/python/script.py end script My script starts another service process and the monitors the processes and sends heartbeat to an outside server regularly. Are startup and shutdown the correct events ? Also my script create a new thread. I'm assuming I also need to add fork daemon to my conf file? Thanks.

  • Unity Launcher and Menu Bar disappeared in 14.04

    - by Justice2497
    The menu bar and Unity launcher have disappeared in Ubuntu 14.04. Also cannot access the terminal via ctrl + alt + t. I have tried every solution for this issue that I can find, from re-installing untiy and compiz to resetting Unity and everything. I've gone into the compiz manager and reactived Unity. Nothing has worked. When trying to reset Unity, or do anything with it really, I get this message (process:6332): dconf-WARNING **: failed to commit changes to dconf: Could not connect: Connection refused EDIT: Installed 14.04 a day ago. The issue happened after a reboot. After installing virtual Box

  • Using RegEx's in Multi-Channel Funnels in Google Analytics

    - by Rob H
    For some reason, I can't get my multi-channel funnel which utilizes RegEx's in the path steps to function -- it keeps coming back with no data. There are a few variables which may be holding things up, but I can't figure out the origin of the problem, nor a solution. Here's the situation: The funnel is tracking conversions, defined as when a user completes 4 steps to signup Steps are not "required" Default URL is set to https://example.com There is a 302 redirect set up on our site that leads from http://example.com to https://example.com Within the funnel, steps switch from non-secure pages (unless browser is set to secure browsing), to secure pages once the user moves from the landing page to the second page of the sign-up process (account placeholder has been created) URL at that point contains the variable of publisher number within (but not at the end) the URL My RegEx's are all properly written as tested on rubular.com

  • When will my old page stop appearing on Google?

    - by Bane
    I recently bought a new address for my Blogger blog, from yannbane.blogspot.com to www.yannbane.com. However, www.yannbane.com addresses do not appear when they are searched for! Is this natural? How much time will it take for Google to update its index? yannbane.blogspot.com 301's to www.yannbane.com. Both are added to my Webmaster Tools account, but it shows no data for www.yannbane.com (strangely). And, finally, is there something I could do to speed up the process?

  • How do I push code to github on shutdown?

    - by Ezequiel
    I switch between working at home and the office, and sometimes, like today, I forget to run a git commit/push. (I find it easy to ignore the command line since I'm still kind of a beginner, there.) How can I make it so that when I shut down my Ubuntu OS, it will follow this process: Check my local code against the github server, executing the rest of this script only if I've made newer changes. Add all new files. Make commits with a basic default comment. Push all changed code to origin master. If anyone knows how to do this, it would be a major assist. Also, anyone know how to do it for Mac OSX? :D

  • Do PHP-FPM (and other PHP handlers) need execute permissions on the PHP files they're serving?

    - by Andrew Cheong
    I read in a post at Server Fault that PHP-FPM needs execute permissions. However, the answer in When creating a website, what permissions and directory structure? only grants read and write permissions to PHP-FPM. Maybe I don't quite understand how PHP handlers (or CGI in general) work, but the two claims seem contradictory to me. As I understand, when Apache / Nginx gets a request for foobar.php, it "passes" the file to an appropriate handler. That is, I imagine it's as if www-root (or apache or whomever the webserver's running as) were to run some command, /usr/sbin/php-fpm foobar.php Actually, no, that's naive, I just realized. PHP-FPM must be a running instance (if it's to be performant, and cache, etc.), so probably PHP-FPM is just being told, "Hey, quick, process this file for me!" In either case, I don't see why execute permissions are necessary. It's not like the webserver needs to literally execute the file, i.e. ./foobar.php Is the Server Fault answer simply mistaken?

  • Rendering order in an Entity System

    - by Daedalus
    Say I use a basic ES approach, and also inside Systems I hold lists of all entities that Systems are required to process. How do I maintain this list of entities in desired rendering order, i.e. for a dumb 2D RenderingSystem? I saw this discussion, and what they suggest is to do something like Z ordering - what I would probably do is just to store a "layer" int in DrawableComponent and then, inside RenderingSystem, just sort entities by mentioned "layer" whenever the entity list for RenderingSystem changes. They also say we could just delete and recreate the entity whenever we want it on the top, but it seems too inflexible to me. How is this problem usually solved?

  • How can I ensure our project gets developed successfully, without having any project management experience? [migrated]

    - by Raven13
    I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. What can I do as a developer without project management experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

  • One True Event Loop

    - by CyberShadow
    Simple programs that collect data from only one system need only one event loop. For example, Windows applications have the message loop, POSIX network programs usually have a select/epoll/etc. loop at their core, pure SDL games use SDL's event loop. But what if you need to collect events from several subsystems? Such as an SDL game which doesn't use SDL_net for networking. I can think of several solutions: Polling (ugh) Put each event loop in its own thread, and: Send messages to the main thread, which collects and processes the events, or Place the event-processing code of each thread in a critical section, so that the threads can wait for events asynchronously but process them synchronously Choose one subsystem for the main event loop, and pass events from other subsystems via that subsystem as custom messages (for example, the Windows message loop and custom messages, or a socket select() loop and passing events via a loopback connection). Option 2.1 is more interesting on platforms where message-passing is a well-developed threading primitive (e.g. in the D programming language), but 2.2 looks like the best option to me.

  • MVP Nomination

    - by Nick Harrison
    I have debated posting this or not. My initial thought was not to post about it. My thought was not to blog about it thinking that I would spare myself the embarrassment if I wasn't awarded. A little paranoid, I know, but these are paranoid times. After more reflection, I realize that there is no embarrassment in not winning. There is great honor in being nominated. Instead of worrying about not winning in the end, I need to enjoy the moment and enjoy being nominated. This is an extreme honor. I would to hear your stories of being nominated? What was the process like? What was your reaction? Hopefully, I will have some good news to share here soon. If not, being nominated truly is an honor.

  • Finding it Hard to Deliver Right Customer Experience: Think BPM!

    - by Ajay Khanna
    Our relationship with our customers is not a just a single interaction and we should not treat it like one. A customer’s relationship with a vendor is like a journey which starts way before customer makes a purchase and lasts long after that. The journey may start with customer researching a product that may lead to the eventual purchase and may continue with support or service needs for the product. A typical customer journey can be represented as shown below: As you may notice, customers tend to use multiple channels to interact with a company throughout their journey.  They also expect that they should get consistent experience, no matter what interaction channel they may choose. Customers do not like to repeat the information they have already provided and expect companies to remember their preferences, and offer them relevant products and services. If the company fails to meet this expectation, customers not only will abandon the purchase and go to the competitor but may also influence others’ purchase decision. Gone are the days when word of mouth was the only medium, and the customer could influence “Six” others. This is the age of social media and customer’s good or bad experience, especially bad get highly amplified and may influence hundreds of others. Challenges that face B2C companies today include: Delivering consistent experience: The reason that delivering consistent experience is challenging is due to fragmented data, disjointed systems and siloed multichannel interactions. Customers tend to get different service quality if they use web vs. phone vs. store. They get different responses from different service agents or get inconsistent answers if they call sales vs. service group in the company. Such inconsistent experiences result in lower customer satisfaction or NPS (net promoter score) numbers. Increasing Revenue: To stay competitive companies frequently introduce new products and services. Delay in launching such offerings has a significant impact on revenue realization. In addition to new product revenue, there are multiple opportunities to up-sell and cross-sell that impact bottom line. If companies are not able to identify such opportunities, bring a product to market quickly, or not offer the right product to the right customer at the right time, significant loss of revenue may occur. Ensuring Compliance: Companies must be compliant to ever changing regulations, these could be about Know Your Customer (KYC), Export/Import regulations, or taxation policies. In addition to government agencies, companies also need to comply with the SLA that they have committed to their customers. Lapse in meeting any of these requirements may lead to serious fines, penalties and loss in business. Companies have to make sure that they are in compliance will all such regulations and SLA commitments, at any given time. With the advent of social networks and mobile technology, companies not only need to focus on process efficiency but also on customer engagement. Improving engagement means delivering the customer experience as the customer is expecting and interacting with the customer at right time using right channel. Customers expect to be able to contact you via any channel of their choice (web, email, chat, mobile, social media), purchase via any viable channel (web, phone, store, mobile). Customers expect companies to understand their particular needs and remember their preferences on repeated visits. To deliver such an integrated, consistent, and contextual experience, power of BPM in must. Your company may be organized in departments like Marketing, Sales, Service. You may hold prospect data in SFA, order information in ERP, customer issues in CRM. However, the experience delivered to the customer must not be constrained by your system legacy. BPM helps in designing the right experience for the right customer and integrates all the underlining channels, systems, applications to make sure right information will be delivered to the right knowledge worker or to the customer every single time.     Orchestrating information across all systems (MDM, CRM, ERP), departments (commerce, merchandising, marketing service) and channels (Email, phone, web, social)  is the key, and that’s what BPM delivers. In addition to orchestrating systems and channels for consistency, BPM also provides an ability for analysis and decision management. By using data from historical transactions, social media and from other systems, users can determine the customer preferences, customer value, and churn propensity. This information, in the context, is then used while making a decision at a process step. Working with real-time decision management system can also suggest right up-sell or cross-sell offers, discounts or next-best-action steps for a particular customer. Timely action on customer issues or request is also a key tenet of a good customer experience. BPM’s complex event processing capabilities help companies to take proactive actions before issues get escalated. BPM system can be designed to listen to a certain event patters then deduce from those customer situations (credit card stolen, baggage lost, change of address) and do a triage before situation goes out of control. If such a situation arises you can send alerts to right people or immediately invoke corrective actions. Last but not least one of BPM’s key values is to drive continuous improvement. Learning about customers past experiences, interactions and social conversations, provide valuable insight. Such insight can be used to improve products, customer facing processes, and customer experience. You may take these insights as an input to design better more efficient and customer friendly sales, contact center or self-service processes. If customer experience is important for your business, make sure you have incorporated BPM as a part of your strategy to design, orchestrate and improve your customer facing processes.

  • How can I recover from a frozen app when connecting over VNC

    - by Pablojim
    I have a htpc running 10.10. It has no keyboard or mouse attached, so I connect over vnc for administration and manual tasks. This usually works fine but every so often an app running in fullscreen mode crashes. All I want to be able to do is kill this app from VNC. Is there a keyboard shortcut to do this that will preserve the VNC connection? If I use CTRL + ALT + F1, I see the terminal but can no longer control it from VNC. Trying to return to the desktop doesn't work either? Any easy process I can follow?
