• What would be a good topic for research on "edge of multiple processors / computers programming" topic?

  - by Kabumbus

  This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• MacBook Pro (with DVI) to HDMI, including audio - possible?

  - by Jason

  I have a MacBook Pro with DVI. I'd like to hook it up to my living room TV for movies and such but I want to keep it out of the way. I already have HDMI cables run to the basement where I have a cable box. Is there something I could you to connect the MBP video and audio to HDMI so I only need the one cable to the TV? I'm looking for a quality picture but I don't want to spend a ton of $. I've googled a bit, but I'm looking for some recommendations.

• Windows 7 Locking Executable Files

  - by James Burgess

  Since I've been using Windows 7 RTM (as opposed to the Beta and RCs), I've been having a peculiar issue with executable files. I first noticed it whilst using Visual Studio, in that when building a project, it would often fail saying that the output file was locked - but the problem has stemmed further. When I've executed an application, closed it (cleanly), and attempted to delete/move/rename/overwrite said file, Windows 7 tells me that the file is locked/access is denied. I've made use of software like LockHunter/Unlocker but it is seemingly unable to remove these locks (most of the time, it shows no locks at all). After about 5-10 minutes, the respective files are unlocked again, but needless to say this is a bit of a workflow-breaker (as it's not simply constrained to VS). I've done the usual tasks of virus/malware scanning, and turned up with absolutely nothing. I've got no peculiar services running, and the problem was not present before I installed a Windows 7 RTM version. Any help is greatly appreciated.

  Earlier this week we asked you to share your tips and tricks for setting up a novice-proof computer; read on to see how your fellow readers ensure friends and relatives have a well protected computer.

• How to connect to my own WiFi using Broadcom STA drivers?

  - by Chris

  I'm trying hard to switch to Linux from Windows because of my engineering project. Unfortunately, everything is against that change! Before I have installed Broadcom STA proprietary drivers, I was seeing on NetworkManager and nm-applet only local radio-internet-access networks. After I installed Broadcom STA, I see my neighbor's wireless network (channel 11, WEP) Neither before nor after the installation is own wireless network available. Computer: Asus Lamborghini VX6 Ubuntu: 12.04 LTS 64-bit Router: ASUS N55U (A1) with newest AsusWRT firmware Network: Channel 5 (tried also 10 and 11, both on 20 and 40MHz bands), WPA2 Personal, 2,4 + 5 GHz (what is not very important, 'cause the wlan card in VX6 is only 2,4GHz). Network works fine on Windows, also through D-Link repeater on the other floor. Unfortunately, same network is invisible to Ubuntu on same machine. I have tried some combinations with other GUIs but it did not work. Are there any better drivers for Ubuntu? I need that network badly, but I'm an Ubuntu newbie, so I don't know how to solve that problem. Please help.

• Add SATA Port to Motherboard?

  - by YAS

  I recently took off the bottom covers to my laptop, an Aspire 6930, and one of the covers was hiding an empty space large enough for a second hard drive. The bit of motherboard that was showing had the solder joints for a SATA port, but no port. What I'm wondering is; If I get a spare SATA port and solder it in would it mess up my motherboard and kill my laptop? I'm not concerned about a clean solder job, I can do that. But if the port is soldered in cleanly if there would be any danger to doing it. It'd be pretty darn awesome to get a second hard drive in my laptop.

• Snow Leopard, PHP, and MySQL

  - by Peter

  I have just installed Snow Leopard and now my PHP/MySQL program ends in a "Segmentation fault". I have been searching the web for a solution, I realize that there are some issues with SL/PHP/MySQL, but I have not found anything that works yet. I downloaded the binary MySQL package mysql-5.1.42-osx10.6-x86_64. I have updated the php.ini file as suggested at various posts. When I run PHP and connect to the MySQL server the behavior is a bit random. In many cases it works fine to connect and read data. In my specific case the PHP program constructs a LOAD DATA LOCAL INFILE ... statement to load data from a text file. It should do several such queries after each other in a loop. It works one time but the halts in a "Segmentation fault". The program worked fine in Leopard, but not now. My versions are: OS 10.6.2, PHP 5.3.0, MySQL 5.1.42

• Is it possible to sync specific router settings across multiple routers?

  - by Betard Fooser

  I recently purchased a second Linksys wireless routers set up on the other side of my home and I am wondering if it is possible to somehow sync particular settings between the two? For instance what I am really after is the "MAC Filter List". I would "like" to be able to maintain the list on both routers without having to manually type in the field values. maybe this isn't possible, or has an easy answer, but hopefully those of you who know will cut me a bit of slack. I tried to "google" the answer to this of course, but it seems any searches with the words "sync" and "router" and/or "wifi" result in pages of people having issues with synching their iOS devices over wifi. I would say that have decent amount of networking knowledge in regards to average home networks, and I imagine in larger businesses / corporations they must have a "simpler" way of maintaining things like this. Any insight to point me in the right direction will be much appreciated.

• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol

• How to check if a server runs in pressing mode

  - by Ice

  Hi there, Layout: i have at customer side a server (win2003 R2 SP2 standard edition 32-bit) with a sql-server 2005 and some databases. This system starts with the /3GB-Switch. The system reports 3.25 GB RAM and taskmanager reports the process of sqlserver.exe with 2758255 K as the process with the highest consumption. The OS separates RAM for applications and for itself, normaly 50:50. But here we have the /3GB-Switch aktivated and i think the part for the applications is more than 50% of RAM. Knowledge (or better not knowledge): Somebody told me that if the OS runs out of memory within his part of RAM, the server runs into pressing mode. Questions: What is this pressing mode? Is pressing mode possible at all in this szenario? What should be done to get more performance out of this sql-server, beside optimizing the database and all this stuff.

• Program to dump ID3 tag structure

  - by grawity

  Is there a program that would dump the complete structure of ID3v2 tags? Not just the frame names and values, but full information such as frame order, text encoding, description encoding (for TXXX frames), presence of unsynchronization, presence of multiple tags... Background: I'm rather curious why some files are incompatible with some programs. For example, some ID3v2.4 tags written by foobar2000 are not read by Winamp; editing with Mutagen fixes them but editing with foobar2000 breaks again. It's not the version or data encoding – most other v2.4 UTF-16 tags work fine... However, if I use foobar2000 to convert the tags to v2.3, then back to v2.4, they start working fine in Winamp – this last bit just does not make any sense. Edit: Linux or/and Windows.

• Easily manage vsftpd virtual users?

  - by Phil

  I have a vsftpd server configured with many virtual users. logins are stored in a Berkeley DB file One configuration file exists for each user to define his permissions (read-only or read-write, home directory, etc.). To do that, I use the user_config_dir parameter (set in vsftpd.conf). I am wondering if it would be possible to manage these virtual users from a simple GUI (such as web interface). I have found some tools but they are limited to generic vsftpd configuration, not virtual users management. Otherwise, PAM-MySQL seems to be a good way to manage users efficiently but only username/password and logs can be stored in database, not permissions. Finally, I've found this thread, but the solution is a bit awkward... Is there any way to easily manage the vsftpd users ?

• How do laptop battery voltages affect runtime?

  - by Bigbio2002

  I ordered a new battery for my faithful XPS M1710. I'm not sure of the voltage of the battery I have now, but the new one that the Dell rep got me (after 3-4 times confirming my phone number and laptop model number) is 14.8v. I was a bit concerned about potential incompatibilities (as most of the other compatible batteries listed were 11.1v), but I figure that there's no way that Dell would "recommend" batteries that wouldn't work or fry your system. Now, my question is, how does voltage affect battery life? If we assume the needed power draw to be constant, a higher voltage would indicate less amperage needed, therefore the battery would last longer before running out, yes? Or am I missing something? For reference: P=I*V P = power I = current V = voltage (duh)

• Rotating wheel with touch (adding momentum and slowing down the initial rate it can be moved

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the momentum of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of momentum then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• unable to properly execute binaries from PHP

  - by Lowgain

  I was building an app on a SUSE box, and had a binary called create_group for instance, which had a suid bit and allowed my PHP app to call exec('create group grpname'); and create a new group (there are others for users, etc). The binary was a small c script that calls setuid(0) and then runs the user creation stuff. This worked perfectly on the SUSE box I recently moved my project to Ubuntu and everything works fine except these binaries. I can run them from the shell and they work okay, but when I get the PHP app to run them it just does nothing. Is there anything Ubuntu would be doing differently that I'm missing?

• Motherboard memory question

  - by JERiv

  I am currently drawing up specs on a new workstation for my office. I am considering the Asus P6X58D for a motherboard. This board's specs list it as supporting 24 gigs of memory. Suppose I were to use six four gig memory cards and then two video cards with 1 gig of memory apiece. Is the maximum supported memory similar to how 32 bit operating systems only have enough address space for 4 gigs of memory? Simply: Will the board post? If so, will the system be able to address all the memory, both the 24 gigs on the ddr3 bus and the 3 gigs on the graphics card?

• Upgrading to x64 results in HTTP 500

  - by Dour High Arch

  I upgraded my development machine to 64-bit Win7, and now when I try to connect to a local ASP.Net project I get: HTTP Error 500 ... Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" failed There are several puzzling things about this; the ASP.Net project was a .Net 2.0 ASMX so it was using C:\Windows\Microsoft.NET\Framework\v2.0.50727. If it updated to x64 without asking me, should it not use C:\Windows\Microsoft.NET\Framework64\v2.0.50727\? Where is C:\Windows\Microsoft.NET\Framework\v4.0.30319\ coming from? I opened IIS Manager and the selected .Net Framework version for my machine is 2.0.50727. Framework version for my default application pool is the same. I am developing in VS2008, which does not even have an option for targeting .Net 4.0.

• Windows 7 XPS Document Writer has stopped working

  - by jamie

  I have successfully used the Windows 7 XPS Document writer for quite a while under windows 7 (64 bit). Now however when i try to print i get prompted twice for the output file name and then get different error messages depending upon the application being used. e.g. Notepad gives a 'The I/O operation has been aborted because of either a thread exit or an application request'. I have disabled and reenabled the XPS facilities of windows features and have similiarly removed and readded the printer. But the end result is the same. I've uninstalled all applications i have installed since the time when i know it worked but this also has not made any difference. Suggestions please!

• DEBIAN repository signing: a step-by-step guide.

  - by jldupont

  I've got many DEBIAN repository for my projects (e.g. EPAPI, erlang-dbus etc.). It seems that now Synaptic wants those to be signed for the packages to appear by default. For the DEBIAN kung-fu masters out there, please provide me with a step-by-step guide to achieving this, please. I've googled a lot but I am still a bit confused on the subject. update: I use a Launchpad PPA now... saves me from all this trouble.

• Migrating to ssh key authentication; implications of adding sbin's to users $PATH

  - by ancillary

  I'm in the process of migrating to key's for authentication on my CentOS boxes. I have it all set up and working, but was a bit taken aback when I noticed service (and other things) didn't work the way I was accustomed to. Even after su'ing to root, still had to call the full path for it to work (which I assume to be expected/normal behavior). I also assume this is because there are different $PATH's for root (what I was using and am used to) and the newly created, key-using user. Specifically, I noticed the sbin's of the world missing from the user path. If I were to add those paths (/sbin/,/usr/sbin/,/usr/local/sbin) to a profile.d .sh script for this new key-loving user, would: I be opening up the system in ways I shouldn't be? I be doing something I needn't do save for reasons of laziness? I create other potential problems? Thanks.

• Windows 8.1 - unfixable grub

  - by Nick

  I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx

• Cannot access windows share

  - by Wrigley

  I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

• Virtual MS Sql Server not consuming enough CPU

  - by rocketman

  We have a Win2008 server 32 bit running as a virtual machine under ESX server. It has 6 CPU cores of 2Gz each and 4GB ram. It's running MS Sql Server 2008 R2 only. Problem: The server is heavily loaded and responds slowly. From windows taskmanagers point of view, it really looks overloaded, CPU wise. However, our external "cloud manager" says it's only using 2.5GHz worth of CPU-cycles in the cluster. I/O times looks "good". We have already tried to set the SQL servers number of working threads from 0(auto) to 256, to no effect. How to tune the VM host, guest or SQL to use all of it's alotted resources? Does it sound possible att all?

• Podcast aggregation - please recommend for Windows 7

  - by bazza-formez

  Hi, I need a good podcast aggregator. I was using Juice 2.2, but that will not work on my new pc which is running Windows 7 (64 bit). Could anyone recommend one please ? I need the following functionality : 1- Subscribe to podcasts (mp3's from radio shows) using rss 2- Have OPML support so I can load up my old subscriptions easily 3- That runs quietly in the backgrond and looks after itself 4- That deletes old episodes automatically after a set time 5- Isn't just designed for an IPOD (I use a simple generic mp3 player to listen). Any ideas? Thanks! Bazza
