  • Devices on one switch can't see devices on another switch

    - by jockey69
    I have RoadRunner Internet cable service hooked to a Motorola Surfboard modem. This is connected to a 10/100 wireless router (located in the garage). Downstairs, I have a ZyXEL GS-108b gigabit switch connected to one port on the router. From this switch I ran connections to a PS3, DVR, Vonage box and a wireless router (Buffalo AirStation 10/100). The Buffalo AirStation works as a wireless AP for other laptops, iPads and cell phones. Upstairs, I have an Asus gigabit switch connected to a gaming desktop, printer, and a media server on FreeNAS (PS3 Media Server on FreeNAS). The router is configured to assign static IPs to both the PS3 and the media server. Problem - I connect a laptop to the switch downstairs after disabling the wireless, thus making sure that I am accessing internet through the wired connection (and the router in the garage). All my computers, iPads and cell phones are able to connect to the internet without a problem. My PS3 connects to the interent with a wired connection but is unable to access the media server (I get a message that no media server is found). I used a wired laptop downstairs (connected to switch downstairs) but am unable to ping either the PS3 or media server! I may be doing something silly but am at my wits' end. Please help!

  • How to allow writing to a mounted NFS partition

    - by Cerin
    How do you allow a specific user permission to write to an NFS partition? I've mounted an NFS share on my localhost (a Fedora install), and I can read and write as root, but I'm unable to write as the apache user, even though all the files and directories in the share on my localhost and remote host are owned by apache. For example, I've mounted it via this line in my /etc/fstab: remotehost:/data/media /data/media nfs _netdev,soft,intr,rw,bg 0 0 And both locations are owned by apache: [root@remotehost ~]# ls -la /data total 24 drwxr-xr-x. 6 root root 4096 Jan 6 2011 . dr-xr-xr-x. 28 root root 4096 Oct 31 2011 .. drwxr-xr-x 4 apache apache 4096 Jan 14 2011 media [root@localhost ~]# ls -la /data total 16 drwxr-xr-x 4 apache apache 4096 Dec 7 2011 . dr-xr-xr-x. 27 root root 4096 Jun 11 15:51 .. drwxrwxrwx 5 apache apache 4096 Jan 31 2011 media However, when I try and write as the apache user, I get a "Permission denied" error. [root@localhost ~]# sudo -u apache touch /data/media/test.txt' touch: cannot touch `/data/media/test.txt': Permission denied But of course it works fine as root. What am I doing wrong?

  • Cookieless Domain redirect in WHM/cPANEL

    - by Patrick Lanfranco
    I am currently trying to get my head around in understanding how to set-up a "cookieless" domain using WHM / Cpanel - unfortunately without any success at this moment. I have a Magento store and I would like to use "cookieless domains" for my media, skin (template) and js files. Magento has a nice feature to define URL for those folders. My current setup is as follows: www.mydomain.com <- main store media.mydomain.com <- subdomain to the media folder (mydomain.com/media/) skin.mydomain.com <- subdomain to the media folder (mydomain.com/skin/) js.mydomain.com <- subdomain to the media folder (mydomain.com/js/) I think it's poinless to have them used as "cookieliess domains" since my Magento installation uses .mydomain.com as cookie domain, so what I would like to achieve is to register a new additional domain and have it point via WHM / cPanel to those specific locations. I have tried to change the A and CNAME records although without any success as they were just simply redirecting from one page to another in the browser (newdomain.com - jump to old.com). What kind of records do I have to set to have this working properly? Some advice would be highly appreciated.

  • NRF Big Show 2011 -- Part 2

    - by David Dorf
    One of the things I love about attending NRF is visiting the smaller booths to see what new innovative ideas have sprung up. After all, by watching emerging technologies we can get a sense of how the retail experience might change. After NRF I'm hoping to write a post on what I found, if anything, so be sure to check back. At the Oracle Retail booth we'll be demonstrating some of the aspects of the changing retail experience. These demos use a mix of GA and experimental components. Here are some highlights: 1. Checkin We wrote a consumer iPhone app we call Store Gateway that lets consumers access information from the store. They'll start by doing a checkin when they arrive that will alert the store manager via another iPhone app we wrote called Mobile Manager. Additionally, we display a welcome messaging using Starmount's digital sign. 2. Receive Offers There are three interaction points where a store can easily make an offer to a consumer: checkin, product scans, and checkout. For this demo we're calling our Universal Offer Engine at checkin to determine the best offer for this particular consumer. This offer is then displayed on the consumer's phone as well as on the digital sign. 3. Scan Products To thwart consumers from scanning product barcodes, we used Store Inventory Management to print QRCodes on shelf label then provided access to a scanner in the Store Gateway iphone app. When the consumer scans the shelf label they are shown product information provided by the retailer. 4. Checkout While we don't have a NFC-enabled mobile phone, we have a NFC chip that can attach to a phone. We're using this to checkout using a reader provided by ViVOTech. Tap the phone on the reader, and the POS accesses the customer#, coupons, and payment information. This really speeds the checkout process. 5. Digital Receipt After the transaction is complete, a digital copy of the receipt is sent to Intuit's QuickReceipts where consumers to store all their digital receipts. There's even an iPhone app that provides easy access to the receipts. This covers about half of what what we'll be showing, so be sure to stop by. I'll also be talking about how mobile is impacting the retail experience at the Wednesday morning session NRF Mobile Retail Initiative: a Blueprint for Action. See you at the Big Show!

  • TDC: The Developer's Conference Day One

    - by Tori Wieldt
    The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!New this year at TDC is the Java University track, sponsored by Oracle.  It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!" At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.Brazilian developers that cannot attend TDC can watch live streaming.

  • OpenGL Fast-Object Instancing Error

    - by HJ Media Studios
    I have some code that loops through a set of objects and renders instances of those objects. The list of objects that needs to be rendered is stored as a std::map, where an object of class MeshResource contains the vertices and indices with the actual data, and an object of classMeshRenderer defines the point in space the mesh is to be rendered at. My rendering code is as follows: glDisable(GL_BLEND); glEnable(GL_CULL_FACE); glDepthMask(GL_TRUE); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnable(GL_DEPTH_TEST); for (std::map<MeshResource*, std::vector<MeshRenderer*> >::iterator it = renderables.begin(); it != renderables.end(); it++) { it->first->setupBeforeRendering(); cout << "<"; for (unsigned long i =0; i < it->second.size(); i++) { //Pass in an identity matrix to the vertex shader- used here only for debugging purposes; the real code correctly inputs any matrix. uniformizeModelMatrix(Matrix4::IDENTITY); /** * StartHere fix rendering problem. * Ruled out: * Vertex buffers correctly. * Index buffers correctly. * Matrices correct? */ it->first->render(); } it->first->cleanupAfterRendering(); } geometryPassShader->disable(); glDepthMask(GL_FALSE); glDisable(GL_CULL_FACE); glDisable(GL_DEPTH_TEST); The function in MeshResource that handles setting up the uniforms is as follows: void MeshResource::setupBeforeRendering() { glEnableVertexAttribArray(0); glEnableVertexAttribArray(1); glEnableVertexAttribArray(2); glEnableVertexAttribArray(3); glEnableVertexAttribArray(4); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, iboID); glBindBuffer(GL_ARRAY_BUFFER, vboID); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), 0); // Vertex position glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 12); // Vertex normal glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 24); // UV layer 0 glVertexAttribPointer(3, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 32); // Vertex color glVertexAttribPointer(4, 1, GL_UNSIGNED_SHORT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 44); //Material index } The code that renders the object is this: void MeshResource::render() { glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } And the code that cleans up is this: void MeshResource::cleanupAfterRendering() { glDisableVertexAttribArray(0); glDisableVertexAttribArray(1); glDisableVertexAttribArray(2); glDisableVertexAttribArray(3); glDisableVertexAttribArray(4); } The end result of this is that I get a black screen, although the end of my rendering pipeline after the rendering code (essentially just drawing axes and lines on the screen) works properly, so I'm fairly sure it's not an issue with the passing of uniforms. If, however, I change the code slightly so that the rendering code calls the setup immediately before rendering, like so: void MeshResource::render() { setupBeforeRendering(); glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } The program works as desired. I don't want to have to do this, though, as my aim is to set up vertex, material, etc. data once per object type and then render each instance updating only the transformation information. The uniformizeModelMatrix works as follows: void RenderManager::uniformizeModelMatrix(Matrix4 matrix) { glBindBuffer(GL_UNIFORM_BUFFER, globalMatrixUBOID); glBufferSubData(GL_UNIFORM_BUFFER, 0, sizeof(Matrix4), matrix.ptr()); glBindBuffer(GL_UNIFORM_BUFFER, 0); }

  • Making sense of S.M.A.R.T

    - by James
    First of all, I think everyone knows that hard drives fail a lot more than the manufacturers would like to admit. Google did a study that indicates that certain raw data attributes that the S.M.A.R.T status of hard drives reports can have a strong correlation with the future failure of the drive. We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors. First errors in re- allocations, offline reallocations, and probational counts are also strongly correlated to higher failure probabil- ities. Despite those strong correlations, we find that failure prediction models based on SMART parameters alone are likely to be severely limited in their prediction accuracy, given that a large fraction of our failed drives have shown no SMART error signals whatsoever. Seagate seems like it is trying to obscure this information about their drives by claiming that only their software can accurately determine the accurate status of their drive and by the way their software will not tell you the raw data values for the S.M.A.R.T attributes. Western digital has made no such claim to my knowledge but their status reporting tool does not appear to report raw data values either. I've been using HDtune and smartctl from smartmontools in order to gather the raw data values for each attribute. I've found that indeed... I am comparing apples to oranges when it comes to certain attributes. I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors. I've also found that Seagate will report many millions of seek errors while Western Digital always seems to report 0. Now for my question. How do I normalize this data? Is Seagate producing millions of errors while Western digital is producing none? Wikipedia's article on S.M.A.R.T status says that manufacturers have different ways of reporting this data. Here is my hypothesis: I think I found a way to normalize (is that the right term?) the data. Seagate drives have an additional attribute that Western Digital drives do not have (Hardware ECC Recovered). When you subtract the Read error count from the ECC Recovered count, you'll probably end up with 0. This seems to be equivalent to Western Digitals reported "Read Error" count. This means that Western Digital only reports read errors that it cannot correct while Seagate counts up all read errors and tells you how many of those it was able to fix. I had a Seagate drive where the ECC Recovered count was less than the Read error count and I noticed that many of my files were becoming corrupt. This is how I came up with my hypothesis. The millions of seek errors that Seagate produces are still a mystery to me. Please confirm or correct my hypothesis if you have additional information. Here is the smart status of my western digital drive just so you can see what I'm talking about: james@ubuntu:~$ sudo smartctl -a /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD1001FALS-00E3A0 Serial Number: WD-WCATR0258512 Firmware Version: 05.01D05 User Capacity: 1,000,204,886,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Jun 10 19:52:28 2010 PDT SMART support is: Available - device has SMART capability.

    - by jwir3
    I'm not sure this is the correct forum, but I'll ask anyway. I have an A/V setup at home that has something like the following: Five Components (actually a few more, like a CD player, but they don't really relate to this question): Older Pioneer Receiver Digital Set Top Box Sony BluRay Player Samsung Plasma TV Speakers The reason for the receiver is so that all the sound can go through the speakers, rather than some going to the TV speakers and some to the external speakers. They are connected as follows: Digital Set Top Box connects via component video to Samsung TV directly via Component 2 (audio goes to Older Pioneer Receiver). Sony BluRay player is connected via HDMI 1 to TV, but audio goes to the receiver. Now, the problem I'm having is that when I have the digital set top box connected, there are times when the Netflix or Hulu streams I watch through the Sony BluRay player (it's connected to a router for internet access) will lose video. What I mean by this is that the sound of the episode will keep playing, but the screen will go black. If I jiggle the component cables, it will often come back. If I disconnect the component cables, it will always come back. I've noticed that one of the connections (the red component cable) doesn't like to sit very well in the component socket in the back of the digital set top box. It seems like there is a bad connection here, but it doesn't seem like this should be affecting the HDMI input at all. What I've noticed, though, is that when I disconnect the digital set top box completely (i.e. remove the component cable from the back of the TV), the problem seems to resolve itself. I'm not talking about actually removing the cable physically, because I thought perhaps the cables were mashing against one another, and possibly jiggling each other loose. To correct this possible problem, I took the component cable completely out of the cable ties it was in in the back of my entertainment center, as well as pulled the digital set top box out from the entertainment center altogether. It's now connected directly to the TV, without any other cables touching it to cause some kind of weird interference or just physical pulling on the cable. Same problem. If, however, I disconnect the component cable and just leave it sitting behind the TV, then the problem goes away. So, my question is this - what could be causing this? Is it a case where it's an improperly shielded component cable that's causing interference with the HDMI input, or something that's wrong with the TV? It's an intermittent problem, so it's difficult to track down. The TV isn't that old, so it's probably still under warranty. I'm just wondering if there is something else I can do that might reduce this problem without having to haul a massive television set out of my house to get repaired/replaced.

  • How to give wife emergency access to logins, passwords, etc.?

    - by Torben Gundtofte-Bruun
    I'm the digital guru in my household. My wife is good with email and forum websites but she trusts me with all our important digital stuff -- such as online banking and other things that require passwords, but also family photos and the plethora of other digital things in a modern home. We discuss relevant actions but it's always me that executes the actions. If I should get "hit by a bus" then my wife would be thoroughly stranded -- she would have no idea what digital stuff is where on our computer, how to access it, what online accounts we have, and their login credentials are. It would also leave my many public appearances (personal websites, email accounts, social networks, etc.) unresolved. To complicate things, I'm one of those people who don't use password as my password everywhere; I use a mix of SuperGenPass and LastPass, and also two-factor authentication whenever possible. I don't have much hope that she would find her way through a written explanation of all that in a stressful situation. I could just tell her that she should ask my tech-savvy twin brother and then entrust him with my LastPass master passphrase. I feel that would have a high chance of success, but it's inelegant and leaves my wife without control of the information. How can I ensure that my wife has access to my digital remains?

  • When spliting MP4s with ffmpeg how do I include metadata?

    - by Josh
    I have a few MP4s that i want to upload to my flickr account but they have a maximum size of 500mb as mine is only about 550 i was planing to simply split them in half then upload them, but i want to make sure all the meta data is included but it does not seem to be. I have tried each of the following with no luck, (at the end of this post i have the original and the new ffprobe outputs): ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4 ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_meta_data SANY0069.MP4:SANY0069A.MP4 SANY0069A.MP4 with the this one I manually produced the individual meta tags that i took from this command ffmpeg -i SANY0069A.MP4 -f ffmetadata meta.txt ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -metadata major_brand="mp42" -metadata minor_version="1" -metadata compatible_brands="mp42avc1" -metadata creation_time="2012-09-29 09:05:50" -metadata comment="SANYO DIGITAL CAMERA CA9" -metadata comment-eng="SANYO DIGITAL CAMERA CA9" SANY0069A.MP4 using the output of the former command i also tried this: ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -f ffmetadata -i meta.txt SANY0069A.MP4 Output: sample output from my first command: ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4 ffmpeg version 0.8.12, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 13 2012 09:57:38 with gcc 4.6.3 20120306 (Red Hat 4.6.3-2) configuration: --prefix=/usr --bindir=/usr/bin --datadir=/usr/share/ffmpeg --incdir=/usr/include/ffmpeg --libdir=/usr/lib64 --mandir=/usr/share/man --arch=x86_64 --extra-cflags='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic' --enable-bzlib --enable-libcelt --enable-libdc1394 --enable-libdirac --enable-libfreetype --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-x11grab --enable-avfilter --enable-postproc --enable-pthreads --disable-static --enable-shared --enable-gpl --disable-debug --disable-stripping --shlibdir=/usr/lib64 --enable-runtime-cpudetect libavutil 51. 9. 1 / 51. 9. 1 libavcodec 53. 8. 0 / 53. 8. 0 libavformat 53. 5. 0 / 53. 5. 0 libavdevice 53. 1. 1 / 53. 1. 1 libavfilter 2. 23. 0 / 2. 23. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'SANY0069.MP4': Metadata: major_brand : mp42 minor_version : 1 compatible_brands: mp42avc1 creation_time : 2012-09-29 09:05:50 comment : SANYO DIGITAL CAMERA CA9 comment-eng : SANYO DIGITAL CAMERA CA9 Duration: 00:08:38.71, start: 0.000000, bitrate: 9142 kb/s Stream #0.0(eng): Video: h264 (Constrained Baseline), yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 9007 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc Metadata: creation_time : 2012-09-29 09:05:50 Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2012-09-29 09:05:50 File 'SANY0069A.MP4' already exists.

  • Parallel processing slower than sequential?

    - by zebediah49
    EDIT: For anyone who stumbles upon this in the future: Imagemagick uses a MP library. It's faster to use available cores if they're around, but if you have parallel jobs, it's unhelpful. Do one of the following: do your jobs serially (with Imagemagick in parallel mode) set MAGICK_THREAD_LIMIT=1 for your invocation of the imagemagick binary in question. By making Imagemagick use only one thread, it slows down by 20-30% in my test cases, but meant I could run one job per core without issues, for a significant net increase in performance. Original question: While converting some images using ImageMagick, I noticed a somewhat strange effect. Using xargs was significantly slower than a standard for loop. Since xargs limited to a single process should act like a for loop, I tested that, and found it to be about the same. Thus, we have this demonstration. Quad core (AMD Athalon X4, 2.6GHz) Working entirely on a tempfs (16g ram total; no swap) No other major loads Results: /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 1 convert -auto-level real 0m3.784s user 0m2.240s sys 0m0.230s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 2 convert -auto-level real 0m9.097s user 0m28.020s sys 0m0.910s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 10 convert -auto-level real 0m9.844s user 0m33.200s sys 0m1.270s Can anyone think of a reason why running two instances of this program takes more than twice as long in real time, and more than ten times as long in processor time to complete the same task? After that initial hit, more processes do not seem to have as significant of an effect. I thought it might have to do with disk seeking, so I did that test entirely in ram. Could it have something to do with how Convert works, and having more than one copy at once means it cannot use processor cache as efficiently or something? EDIT: When done with 1000x 769KB files, performance is as expected. Interesting. /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 1 convert -auto-level real 3m37.679s user 5m6.980s sys 0m6.340s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 1 convert -auto-level real 3m37.152s user 5m6.140s sys 0m6.530s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 2 convert -auto-level real 2m7.578s user 5m35.410s sys 0m6.050s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 4 convert -auto-level real 1m36.959s user 5m48.900s sys 0m6.350s /media/ramdisk/img$ time for f in *.bmp; do echo $f ${f%bmp}png; done | xargs -n 2 -P 10 convert -auto-level real 1m36.392s user 5m54.840s sys 0m5.650s

  • Samba doesnt require password on xbmc but does on ubuntu

    I have samba setup on a fedora 13 machine, and I use it to share with my xbmc client in the family room. When I set this up there no password or anything was required I merely entered in paths such as: smb://<host>/<share> and all worked.

  • how to remove obsolete device and network entries? Device manager "uninstall" option has no effect

    - by Gizmo
    I am trying to remove a few "obsolete" things which annoy me (because I like to have everything cleen, working and not interferring with each other, fresh, etc..). I tried looking for solutions without any help, so here I am to ask. My first part is about removing obsolete networks, let me explain by showing the ipconfig output: C:\windows\system32>ipconfig Windows IP Configuration Wireless LAN adapter Local Area Connection* 11: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Wireless LAN adapter Local Area Connection* 9: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Ethernet adapter LAN: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Wireless LAN adapter Wi-Fi: Connection-specific DNS Suffix . : home Link-local IPv6 Address . . . . . : fe80::c129:8d57:bbd1:3564%10 IPv4 Address. . . . . . . . . . . : 192.168.2.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.2.254 Tunnel adapter isatap.home: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : home C:\windows\system32> Specificalyy the first two adapter entries annoy me because the adapters are not visible in the network connection menu (invisible folder / file visibility set to "show"): And here is the second problem altogether with the first one: No matter what I click/do, Uninstall option has no effect on the multiplexor driver. (bridging stuff, right?) I really want to remove the Wireless LAN adapter Local Area Connection entries and the adapter multiplexor stuff but it's impossible? Why is this? How can I remove them anyway?

  • #1 O’Reilly eBook for 2010

    - by Jan Goyvaerts
    The year-end issue of O’Reilly’s author newsletter discussed the trends O’Reilly has been seeing the past few years, and their predictions for 2011. The key trend is that digital is now more than ever poised to take over print: Our digitally distributed products have grown from 18.36% of our publishing mix in 2009 to 28.09% of our mix in 2010. What is more impressive is that our digitally distributed products have produced more than double the revenue that has been lost with the decline of print. I think this is important because some say that digital cannibalizes print products. Our data indicates the contrary, as print is declining much more slowly than digital is growing. I think we may be seeing developers purchasing a print book, and then purchasing the electronic editions to search and copying code from, as the incremental cost for digital is more than reasonable. My own book seems to be leading this trend. Thanks to everyone who purchased it! And the five bestselling O’Reilly ebook products for 2010: 1) Regular Expressions Cookbook, 2) jQuery Cookbook, 3) Learning Python, 4) HTML5: Up and Running, and 5) JavaScript Cookbook. I think it’s interesting that the top five ebooks are code-intensive books. They’re great products for search and code reuse. It’s also interesting that none of the top 5 ebooks made the top 5 of print books.

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • The Freemium-Premium Puzzle

    The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

  • Linux C++: Linker is outputting strange errors

    - by knight666
    Alright, here is the output I get: arm-none-linux-gnueabi-ld --entry=main -dynamic-linker=/system/bin/linker -rpath-link=/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -L/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -nostdlib -lstdc++ -lm -lGLESv1_CM -rpath=/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -rpath=../../YoghurtGum/lib/Android -L./lib/Android intermediate/Alien.o intermediate/Bullet.o intermediate/Game.o intermediate/Player.o ../../YoghurtGum/bin/YoghurtGum.a -o bin/Galaxians.android intermediate/Game.o: In function `Galaxians::Init()': /media/YoghurtGum/Tests/Galaxians/src/Game.cpp:45: undefined reference to `__cxa_end_cleanup' /media/YoghurtGum/Tests/Galaxians/src/Game.cpp:44: undefined reference to `__cxa_end_cleanup' intermediate/Game.o:(.ARM.extab+0x18): undefined reference to `__gxx_personality_v0' intermediate/Game.o: In function `Player::Update()': /media/YoghurtGum/Tests/Galaxians/src/Player.h:41: undefined reference to `__cxa_end_cleanup' intermediate/Game.o:(.ARM.extab.text._ZN6Player6UpdateEv[_ZN6Player6UpdateEv]+0x0): undefined reference to `__gxx_personality_v0' intermediate/Game.o:(.rodata._ZTIN10YoghurtGum4GameE[_ZTIN10YoghurtGum4GameE]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info' intermediate/Game.o:(.rodata._ZTI6Player[_ZTI6Player]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' intermediate/Game.o:(.rodata._ZTIN10YoghurtGum6EntityE[_ZTIN10YoghurtGum6EntityE]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' intermediate/Game.o:(.rodata._ZTIN10YoghurtGum6ObjectE[_ZTIN10YoghurtGum6ObjectE]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info' intermediate/Game.o:(.rodata._ZTI6Bullet[_ZTI6Bullet]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' intermediate/Game.o:(.rodata._ZTI5Alien[_ZTI5Alien]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' intermediate/Game.o:(.rodata+0x20): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' ../../YoghurtGum/bin/YoghurtGum.a(Sprite.o):(.rodata._ZTIN10YoghurtGum16SpriteDataOpenGLE[_ZTIN10YoghurtGum16SpriteDataOpenGLE]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info' ../../YoghurtGum/bin/YoghurtGum.a(Sprite.o):(.rodata._ZTIN10YoghurtGum10SpriteDataE[_ZTIN10YoghurtGum10SpriteDataE]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info' make: *** [bin/Galaxians.android] Fout 1 Here's an error I managed to decipher: intermediate/Game.o: In function `Galaxians::Init()': /media/YoghurtGum/Tests/Galaxians/src/Game.cpp:45: undefined reference to `__cxa_end_cleanup' /media/YoghurtGum/Tests/Galaxians/src/Game.cpp:44: undefined reference to `__cxa_end_cleanup' This is line 43 through 45: Assets::AddSprite(new Sprite("media\\ViperMarkII.bmp"), "ship"); Assets::AddSprite(new Sprite("media\\alien.bmp"), "alien"); Assets::AddSprite(new Sprite("media\\bat_ball.bmp"), "bullet"); So, what seems funny to me is that the first new is fine (line 43), but the second one isn't. What could cause this? intermediate/Game.o: In function `Player::Update()': /media/YoghurtGum/Tests/Galaxians/src/Player.h:41: undefined reference to `__cxa_end_cleanup' Another issue with new: Engine::game->scene_current->AddObject(new Bullet(m_X + 10, m_Y)); I have no idea where to begin with the other issues. These are my makefiles, They're a giant mess because I'm just trying to get it to work.
