• Unable to set .NET 4 on Application Pool from remote, works locally on server

  - by Robin Wassén-Andersson

  I have setup Remote Administration for IIS successfully and connected to it. For some reason .NET Framework 4 doesn't show up as an option when configuring the Application Pools from remote even though .NET 4 is installed on both server and client (not that client should matter). If I login to the server with RDP and configure the Application Pools it work as intended, the option shows up. Even more odd is if I edit an Application Pool that already runs .Net 4 it shows up as an alternative (kind of strangly formatted text though, just says v4.0 instead of .NET Framework v4.0.30319 ) How should I proceed to solve this?

• PPTP: Linux clients unreachable

  - by Bahman

  I have setup a PPTP server on a CentOS 6 box. Several clients (Windows and Linux) connect to this server. All clients use the same subnet. All clients (Win or Lin) can surf the Internet using the VPN successfully. Windows clients can ping any other Windows client (XP/Vista/7) connected to VPN. Linux clients (KVPNC) can ping any Windows client (XP/Vista/7) connected to VPN. So far so good. But there's this weird problem and I've been trying to figure it out with no luck: No client can ping (reach) a Linux client (successfully) connected to VPN. And yes, the firewall is completely disabled. I'd really appreciate any hint/idea. TIA, EDIT: The ultimate goal of this is to share services across the VPN, like accessing a HTTPD running on a Linux box from a Windows client.

• Can I remove a RAR file's (known) password without recompressing the archive?

  - by Abluescarab

  Long title. Anyway, I haven't been able to find an answer to this question. I know the password to the RAR file, I locked it myself, but now all I want to do is remove the password because it's too much of a pain in the butt to type it in every time. Is there a way to do this in WinRAR or an equivalent program? The only thing I knew to do was to extract it, then create a new RAR without the password. It's not a life-or-death issue, but it would be nice to know. Thanks for your time! EDIT: I just saw a bunch of related questions that appear to ask the same thing. The only solution I saw was using a DOS command to yadda yadda yadda. Here it is: How to remove password protection from compressed files Is there an easier way? Thanks again!

• Will my RAID0 stay intact when I move it to a new computer?

  - by Jeremy H

  My primary drive is a 250GB WD SATA drive. So, I added 2x 500GB 7,200 RPM WD SATA drives into my Windows Vista box and created a 1TB RAID0. I then formatted the the primary drive and installed Windows 7. To my pleasant surprise when I booted into Windows 7 my RAID0 was still intact and I kept trotting along the same as I did before. Now I am replacing my motherboard, processor, and RAM and plan on formatting the primary 250GB drive again and using it to boot for a new clean install of Windows 7. My question is: if I move these two SATA drives which are setup for RAID0 into the new system, install Windows 7 again, will the RAID0 remain? Edit: Software RAID. I created it within Windows. The RAID0 does NOT contain the system boot partition.

• Lots of files being used by blank web page. What are they?

  - by byronyasgur

  I am trying to optimise a website and I was using the network waterfall facility in Google Chrome. When I looked at the results there were lots of files which I didnt recognise. I first thought they might be something to do with Google Chrome itself, so I put a blank HTML file on my desktop and checked but there was nothing in the waterfall except the file itself. So I put a blank file on my server and I got the output below. What are all these files, are they all necessary, is this normal and do I need to be in any way concerned. My hosting provider has always been excellent in every regard that I'm aware of. My host is shared hosting, using cpanel and is based on a LAMP server. I also note that a couple of those file have problems but I have no idea how to fault find that or whether it's a concern. EDIT: I have cleared the cache so I don't think it's a browser cache issue.

• Wireless only connects to Google

  - by dmanxiii

  I am using a netgear wireless router to connect to create a wireless network. When connected to the router via an Ethernet cable everything works correctly. When connecting to the router via wireless only Google can be accessed. I've done searches via Google using random words to make sure that it is not a cached page, and these all work. However, trying to connect to any non Google domain the page fails to load. I've accessed the connection with two different laptops, both are running Windows Vista. The network connection is strong on both, but the issue persists for both. Edit: I have configured the wireless networks name and password, and connect to that using the credentials I have defined. I am sure I am not connecting to a neighbors wireless network. Edit2: Typing in the direct IP address for CNN.com ( http://157.166.255.19 ) would not resolve.

  I'm trying to port opencloth example to OpenGL 3.x. I've mostly done it to the shaders but I'm not sure of this part : glEnableClientState(GL_VERTEX_ARRAY); glBindBuffer(GL_ARRAY_BUFFER, vboID); glVertexPointer(4, GL_FLOAT, 0,0); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glBindBuffer(GL_ARRAY_BUFFER, vboTexID); glTexCoordPointer(2, GL_FLOAT,0, 0); glEnableClientState(GL_NORMAL_ARRAY); glBindBuffer(GL_ARRAY_BUFFER, vboNormID); glNormalPointer(GL_FLOAT,sizeof(float)*4, 0); maybe glEnableVertexAttriArray somewhere ? any clue ? thanx edit : maybe something like that ? glEnableVertexAttribArray (2) ; // Ou glEnableVertexAttribArray (positionIndex) ; glBindBuffer(GL_ARRAY_BUFFER, vboTexID); glVertexAttribPointer (2, 2, GL_FLOAT, GL_FALSE, 0, 0) ; glEnableVertexAttribArray (3) ; // Ou glEnableVertexAttribArray (positionIndex) ; glBindBuffer(GL_ARRAY_BUFFER, vboNormID); glVertexAttribPointer (3, 4, GL_FLOAT, GL_FALSE, sizeof (float) * 4, 0) ;

• Ubuntu 14.04: Fine tuning Touchpad for ThinkPad S431

  - by ramgorur

  I am using Ubuntu 14.04 on Lenovo ThinkPad S431. The touchpad is very bumpy, tricky to use. Slides down with a small touch, sometimes jerks erratically. I have tried to modify the settings in /usr/share/X11/xorg.conf.d/50-synaptics.conf file as below -- Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "JumpyCursorThreshold" "250" Option "VertResolution" "100" # Option "HorizResolution" "65" # Option "MinSpeed" "1" # Option "MaxSpeed" "1" # Option "AccelerationProfile" "1" # Option "AdaptiveDeceleration" "8" # Option "ConstantDeceleration" "1" # Option "VelocityScale" "128" Option "HorizHysteresis" "150" Option "VertHysteresis" "150" EndSection There are lots of options here, does anyone know how to get a fine-tuned values for the above options (for ThinkPad S431)? The Hysteresis values seems to alleviate the problem a little bit, but failed to get a perfect result. EDIT: According to this bug report for ThinkPad X230 (+X230t), I set these values and quite good for now -- Option "VertResolution" "100" Option "HorizResolution" "65" Option "MinSpeed" "1" Option "MaxSpeed" "1" Option "AccelerationProfile" "2" Option "AdaptiveDeceleration" "16" Option "ConstantDeceleration" "16" Option "VelocityScale" "32" Option "HorizHysteresis" "50" Option "VertHysteresis" "50" and then you need to increase the cursor speed manually from the Unity mouse settings. But I am still looking for a fully functional (possibly with all the gestures) and a fine-tuned touchpad settings for S431. Further help is appreciated.

• Customizing The Fusion Applications Simplified UI (aka FUSE)

  - by Richard Bingham

  Everyone who has seen it is impressed by the new Simplified UI, providing self-service workers the ease-of-use that they expect from a modern web application. As always, people want and need to make small adjustments, especially in the Cloud, and thankfully even in its first release there is good support for this. The main features are: Configuring the branding and look-and-feel (known as a theme) of the Simplified UI. Adding you own custom announcements to the Simplified UI homepage. Using Page Composer to edit component properties, such as re-label text or hiding unwanted fields. Using MDS Sandboxes to manage groups of related customizations. Using Application Composer to adjust the fields available in certain Simplified UI pages. These are demonstrated in the video embedded below, available as part of our YouTube channel, as well as being documented in the extensibility guide. &amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; As mentioned, this is the first release of this capability so if there is something you're stuck on please use our forum and we'll try to help, or if you have a requirement for a new Simplified UI customization, please add a comment below.

• Why does my mic boost automatically go to 100 on every boot?

  - by Ben

  When my computer turns on, it automatically sets the "mic boost" sound setting to 100. This causes a loud static sound in my speakers. I can manually go to alsamixer and turn the mic boost down manually, but I would prefer it if I didn't have to do this every time I turn the computer on. I've tried running sudo alsactl store after fixing the settings, and this does save them, but I have to run sudo alsactl restore to restore the settings. This means that I have to manually fix the sound every time I start the computer anyway, so it isn't really a fix. I tried putting sudo alsactl restore in my startup programs, but that didn't seem to fix anything. I'm running Ubuntu 12.04, but I started having this problem before upgrading from 11.10. I'm using a Sony Vaio laptop. I'm not really sure what made it start; it seemed like I just started having the problem randomly one day. Any help would be appreciated! Edit: here is the output from running amixer: http://paste.ubuntu.com/1060080/

• Cannot establish ssh connection to computer on local network

  - by ovangle

  I've just (re)installed ubuntu 11.10 on my main pc, and the connection times out every time I try to ssh connect to my laptop (over the local network) to retrieve the files I backed up there. The connection times out every time I try to connect. I can establish a connection in the other direction without issue. Here's the verbose output I get when I try to connect: ovangle@ruby-EP43-DS3:~$ ssh -v [email protected] OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.1.1.4 [10.1.1.4] port 22. debug1: connect to address 10.1.1.4 port 22: Connection timed out ssh: connect to host 10.1.1.4 port 22: Connection timed out ssh is installed on both machines, and I've tried deleting '~/.ssh/known_hosts' on both machines, still nada. I've changed the sshd logging on the laptop to VERBOSE and restarted the daemon (because I wasn't getting any relevant syslog entries otherwise), and this is the log for the most recent connection attempt. EDIT: posted wrong logs last time. They just showed that there was a connection received, they weren't actually the sshd logs (which were in auth.log as I recently discovered). Unfortunately, that log is filling up with extremely weird error messages and it gives me no information about the connection.

• 3D collision physics. Response when hitting wall, floor or roof

  - by GlamCasvaluir

  I am having problem with the most basic physic response when the player collide with static wall, floor or roof. I have a simple 3D maze, true means solid while false means air: bool bMap[100][100][100]; The player is a sphere. I have keys for moving x++, x--, y++, y-- and diagonal at speed 0.1f (0.1 * ftime). The player can also jump. And there is gravity pulling the player down. Relative movement is saved in: relx, rely and relz. One solid cube on the map is exactly 1.0f width, height and depth. The problem I have is to adjust the player position when colliding with solids, I don't want it to bounce or anything like that, just stop. But if moving diagonal left/up and hitting solid up, the player should continue moving left, sliding along the wall. Before moving the player I save the old player position: oxpos = xpos; oypos = ypos; ozpos = zpos; vec3 direction; direction = vec3(relx, rely, relz); xpos += direction.x*ftime; ypos += direction.y*ftime; zpos += direction.z*ftime; gx = floor(xpos+0.25); gy = floor(ypos+0.25); gz = floor(zpos+0.25); if (bMap[gx][gy][gz] == true) { vec3 normal = vec3(0.0, 0.0, 1.0); // <- Problem. vec3 invNormal = vec3(-normal.x, -normal.y, -normal.z) * length(direction * normal); vec3 wallDir = direction - invNormal; xpos = oxpos + wallDir.x; ypos = oypos + wallDir.y; zpos = ozpos + wallDir.z; } The problem with my version is that I do not know how to chose the correct normal for the cube side. I only have the bool array to look at, nothing else. One theory I have is to use old values of gx, gy and gz, but I do not know have to use them to calculate the correct cube side normal.

• issues with ASUS S301L ultrabooks

  - by Wuerze

  I just like to tell you what still is a Problem in Ubuntu 14.04 and should be solved for a nice experience of this distribution. Unfortunately I do not have any hints to tell you, because I am just a user and know not much about programming. Anyway, I hope it helps. 1) Intel open source Graphics issues (proprietary) -when attaching HDMI-cable the screen switches to the external monitor and it's fine, but there is no switching back unless restart with HDMI deattached -black screen appears for like 2 seconds as if I would change screen in the settings; frequency increases with intensity of driver use (i.e. videos or video games) 2) hotkeys (commonly recognised) -there is no possibility to adjust brightness with the hotkeys (Fn+F5 and Fn+F6) 3) touchscreen (commonly recognised) -the touchscreen is behaving like a mouse -configuring gestures for the multi touch screen seems to always end in disabling touch pad gestures 4) panel symbols -battery symbol has got a low accuracy while it determines accurately the energy left; only 5 steps of energy are shown by the symbol Thank you all for participating in the solution of these problems! I will stay tuned and edit this list if something has been solved.

• How far should one take e-mail address validation?

  - by Mike Tomasello

  I'm wondering how far people should take the validation of e-mail address. My field is primarily web-development, but this applies anywhere. I've seen a few approaches: simply checking if there is an "@" present, which is dead simply but of course not that reliable. a more complex regex test for standard e-mail formats a full regex against RFC 2822 - the problem with this is that often an e-mail address might be valid but it is probably not what the user meant DNS validation SMTP validation As many people might know (but many don't), e-mail addresses can have a lot of strange variation that most people don't usually consider (see RFC 2822 3.4.1), but you have to think about the goals of your validation: are you simply trying to ensure that an e-mail address can be sent to an address, or that it is what the user probably meant to put in (which is unlikely in a lot of the more obscure cases of otherwise 'valid' addresses). An option I've considered is simply giving a warning with a more esoteric address but still allowing the request to go through, but this does add more complexity to a form and most users are likely to be confused. While DNS validation / SMTP validation seem like no-brainers, I foresee problems where the DNS server/SMTP server is temporarily down and a user is unable to register somewhere, or the user's SMTP server doesn't support the required features. How might some experienced developers out here handle this? Are there any other approaches than the ones I've listed? Edit: I completely forgot the most obvious of all, sending a confirmation e-mail! Thanks to answerers for pointing that one out. Yes, this one is pretty foolproof, but it does require extra hassle on the part of everyone involved. The user has to fetch some e-mail, and the developer needs to remember user data before they're even confirmed as valid.

• How to reset the language of the package descriptions

  - by xubuntix

  I have had German as my main language about a year ago. Later I changed it to English. Most parts of the system accepted the change. The notable exceptions are the package descriptions, which remain in German for some packages. You can see in the image (apt-cache and software-center), that while some descriptions are in English, some have remained in German. So the question is: how do I reset this? I guess that there is somewhere a description cache that needs to be told that it should update all descriptions? EDIT: As asked: the output of some language related commands: $ cat /etc/default/locale LANG="en_US.UTF-8" $ apt-config dump | grep Lang Acquire::Languages ""; Acquire::Languages:: "de_DE"; Acquire::Languages:: "de"; Acquire::Languages:: "en"; Acquire::Languages:: "none"; $ locale LANG=de_DE.UTF-8 LANGUAGE=en LC_CTYPE="de_DE.UTF-8" LC_NUMERIC="de_DE.UTF-8" LC_TIME="de_DE.UTF-8" LC_COLLATE="de_DE.UTF-8" LC_MONETARY="de_DE.UTF-8" LC_MESSAGES="de_DE.UTF-8" LC_PAPER="de_DE.UTF-8" LC_NAME="de_DE.UTF-8" LC_ADDRESS="de_DE.UTF-8" LC_TELEPHONE="de_DE.UTF-8" LC_MEASUREMENT="de_DE.UTF-8" LC_IDENTIFICATION="de_DE.UTF-8" LC_ALL= As a note: I'm not sure what each entry means, but some of the de_DE.UTF-8 are probably ok, since I do want paper-sizes, monetary, time, etc. in standard German formats.

• Updated 12.04 and now Xorg is dead from NVidia drivers

  - by Xatolos

  I updated (August 16) Ubuntu 12.04 today and while I admit I didn't look what was being updated, it was large enough to have had an NVidia update in it. Problem is later on when I turned on my laptop again it won't boot into a GUI, just to the terminal (which I don't really know much of how to do anything). Now I have been able to log in and type "startx" to start up the GUI and now its complaining that my NVidia driver (if I remember correctly) is listed as being version 304.(number) and the version installed/found is version 295.(number). I don't know how this happened and now I'm stuck. I have no idea how it happened and don't know how to fix. Does anyone have any ideas? I have only access to wifi internet and no idea how to log on without the GUI so getting a new NVidia package isn't something I would know how to do even... Any and all help would be highly appreciated. edit: If it helps, I'm using a ASUS G Series G53JW-A1 http://www.newegg.com/Product/Product.aspx?Item=N82E16834220861

• Root access amazon ec2

  - by mazzzzz

  Hey guys, I am very new to linux, and amazon-ec2. I wanted to put a quick server. For some reason, when I sign in with my key pair, it prompts me for a username, I input ec2-user, and I'm in. The problem is that I don't have root access (and can't find the root password). I need to install screen to run the server in the background, and also create a new user, that doesn't have root, to run the server. Neither of which I can do without root.. Any help? Edit: I am using Basic 32-bit Amazon Linux AMI 2010.11.1 Beta as the 'AMI'. Thanks, Max

• Should all my files be stored on my shared partition?

  - by James

  I am setting up a tripple boot HD and was going to use a 4th partition to share files between OS's. I was wondering if there is any point in having much space on each OS partition to store files or if I just make the shared partition big and put everything on that? Is there any difference in speed between accessing files on the shared partition vs the native files? Are there any other benefits/disadvantages of having files on either the native/shared partition? EDIT: OS's in question are Windows 7, Ubuntu 12.04, and OS X 10.7.4.

• One site being on a subdirectory of another. Does google count this againt you?

  - by Mick

  I have created two similar websites (relating to monetary systems). So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for the successful one, but less liked one is just an "add-on" which sits on a subdirectory of the successful one. I wonder if Google somehow detects this and treats it as a less significant website? EDIT: Just to clarify, even though one site is an add-on that sits on a subdirectory of the other, the URL is arranged to look like it is a root. I.e. the unpopular site can be accessed directly with a simple www.myunpopularsite.com name, without specifying any subdirectory.

• Tuning MySQL to consume less memory

  - by Alex

  I have a VM which has 2GB Ram, (full specs) And I am setting up a site which has one table in particular with over a million records. There's little or no usage of this particular database (perhaps once or twice a day) but simply running mysql grinds the whole server to a halt. I've looked through the top results but nothing is really denting the CPU however the memory seems to be the issue. The site isnt even live of taking requests yet. the memory situation looks like this: # free -m total used free shared buffers cached Mem: 2006 1880 126 0 3 53 -/+ buffers/cache: 1823 183 Swap: 2047 345 1702 Are there any good pointers to tune mysql to stop hogging the system memory? Thanks very much EDIT: (requested by 8bit): http://tny.cz/b41a0b12

• Just installed 13.10 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.10 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• What is an Acer Converter Port?

  - by ShadowHero

  What is this port "Acer Converter Port"? Very little information can be found on the internet. It's basically the same as miniDP? Can I connect a monitor like Dell U2713H on this one? EDIT From this page: http://acer.custhelp.com/app/answers/detail/a_id/30837/~/frequently-asked-questions-on-the-aspire-r7-series 9. Can I connect a DisplayPort monitor to the Acer Converter Port? The Acer Converter Port uses the same physical port as a Mini DisplayPort, but is designed to connect to an Acer proprietary cable. If you connect a DisplayPort monitor, Acer cannot guarantee the functionality of the monitor. No damage should occur to either monitor or notebook by connecting a Mini DisplayPort cable. So, the question is, can someone confirm this will work for sure?

• Notepad++ tabbing out of tags, autocomplete

  - by Matt

  I'm trying to learn a little HTML. Everyone says to use Notepad++ over notepad. I have autocomplete on. My question: When I type my opening tag and Notepad++ then puts"""" closing tag, how do I "jump" out of the tag when I'm done typing? If I tab or hit enter, I'm still stuck before the closing tag. I can use my arrow keys, but if I'm going to do that, I would rather just type the closing tags. Also if I have an UL of 10 items, and I want to change it to an OL, how do I select both the opening and closing tags so I may edit them at the same time? Thanks PS I wasn't able to post the HTML tags.
