• KDE not loading without nomode tag in grub and bad resolution [migrated]

  - by fcole90

  I recently installed Linux Mint 13 KDE but it's not working fine. At first I had to use failsafe mode to boot because normal boot takes to a textual login. If I use normal boot and text login I'm not able to run KDE nor with kdm start neither with startx. kdm says that's already running. Instead X is not able to run because can't connect Xserver to display. If I stop kdm and starx again doesn't change anything. Now I edited the grub to load in nomode. In that way KDE loads but resolution is wrong and xrandr doesn't help, because if I do this: cvt 1366 768 it changes it to 1368: # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync I also installed bumblebee and nvidia drivers because of optimus technology.. It worked just to have fun with glxspheres but there isn't any gain on KDE..

• Need recommendation for transferring ASP.NET MVC skills to PHP

  - by Tuck

  I am looking to translate my skills in .NET to PHP - specifically in regards to ASP.NET MVC. At work I am currently using .NET MVC 2.0 on a variety of projects and thoroughly enjoy the platform. Specifically I enjoy the very minimal configuration required to get a project up and running (just create the project, define routes, and start coding), as well as the ability for controller actions to return different items (i.e. ActionResult, JsonResult). Another piece I really like is the way the view/model interaction can be handled. For example I like being able to call return View(model) and having a view page (.aspx) load and having the full model object available to the view, regardless of the model type. I'm looking for a PHP implementation of MVC that is the most similiar to what I am already familiar with. I don't anything apart from the MVC functionality. I've looked at Zend, Symfony, CodeIgniter, etc. and, while they look like they'll be fun to play with in the future, they provide much more functionality than I need. I'd prefer to write my own DAL, form helpers, delegate handlers, authentication/ACL pieces, etc. In short, I just need something to handle the routing and view interactions and will worry about the model implementation myself. Can someone please point me to some lightweight code that accomplishes or comes close to accomplishing my objectives above. Or, can someone identify just the portions of a larger framework that do the same (again, I'm not currently interested in implementing something on a big framework, just the MVC portion and want to implement the model portion myself as much as possible). Thanks in advance.

• Apache Slow Over http, Fast Over https

  - by Josh Pennington

  I have an Apache server running Debian. I am having this very strange situation where loading a page takes about 2 to 3 times longer to load over http than https. The primary use of the website is Magento, but I am seeing similar results with other things that we have loaded on the website. I don't have the first clue where to even look on our server or what the problem could be. Does anyone have any insight as to what could be going on or where to look. Josh

• IIS7 Compression Configuration

  - by Level1Coder

  Hi, Previously when I used IIS6, I used IIS6 Metabase Explorer to edit Metabase.xml and manually turned on compression, specified the compression level and the file extensions to compress. IIS7 seems a bit different, there is no Metabase.xml file in the system32\inetsrv folder. Enabling compression is easy to turn on by checking the checkbox in the Compression module. But how do I manually tweak and set the compression levels and file extensions to compress? I also ran across an article saying that IIS7 also automatically throttles the compression if your CPU load is 50% then compression is turned off. Where are all these settings located?

• php APC uptime problem

  - by hamlet

  I am on LAMP with Alternative PHP Cache. It worked fine until yesterday when I updated the website and changed a few mySQL queries (I don't see the how it would affect APC opcode cache) Today I see that the load has increased on the server and I see in Alternative PHP Cache, that the uptime of APC is somewhere around 15 minutes then it gets restarted. At this point the APC cache is only about 20% full of the available 30Mb. Using for opcode cache only. During this 15 minutes the cache works fine (99,8% cache hits). After this unwanted restart the APC cache is empty. Why is it restarting? Where can I find the logs for it? Thanks, Hamlet

• My IIS server won't serve SSL sites to some browsers

  - by sbleon

  (Update: This is now cross-posted at http://stackoverflow.com/questions/3355000. This is the more appropriate forum, but StackOverflow gets a lot more traffic.) I've got an IIS 6.0 server that won't serve pages over SSL to some browsers. In Webkit-based browsers on OS X 10.6, I can't load pages at all. In MSIE 8 on Windows XP SP3, I can load pages, but it will sometimes hang downloading images or sending POSTs. Working: Firefox 3.6 (OS X + Windows) Chrome (Windows) Partially Working: MSIE 8 (works sometimes, but hangs up, especially on POSTs) Not Working: Chrome 5 (OS X) Safari 5 (OS X) Mobile Safari (iOS 4) On OS X (the easiest platform for me to test on), Chrome and Firefox both negotiate the same TLS Cipher, but Chrome hangs on or after the post-negotiation handshake.

• Cannot access or open Facebook messages [migrated]

  - by Ehsan Mamakani

  I was up to sending a very long message, about 90,000 characters, to a friend, I tried several times but I got an error sending the message. Finally, I think part of my message was sent because I could see the characters in my message list under my friend's name. When I clicked the name to see my whole message it wouldn't load the message. And now I can't access any of my messages and I get this message from Facebook: Sorry, messages are temporarily unavailable. Please try again in a few minutes. How can I get access to my messages and conversations again?

• BixData or Zabbix?

  - by Arafat

  Hi all, I've been using Ganglia to monitor my single Mac OSX server which runs Apache and MySQL. I'm ok with it. Now we are upgrading our servers, 6 IBM X3650 M3 and 2 Fujitsu servers. 2 IBM for Apache cluster and 4 IBM for MySQL NDB Cluster. The other two servers are for Load balancers. All servers are going to run Debian Lenny 5 on it. Now I need to decide on which monitoring tool I should go for. I found that BixData and Zabbix does an excellent job than Ganglia, in terms of sensors and reporting. Have anyone tried the above two tools? And which tool would you suggest me? For Debian. As I'm writing this, I'm installing BixData to try.... Thanks in advance.

• Configuring Server with no monitor

  - by Scandalist

  Sitting in front of me is an HP DL 380 Generation 4 with no monitor. I'd like to install an OS on the thing but for reasons obvious, I can't. I got excited when I found the ILO port on the back but unless you have a subscription it has limited functionality. I was thinking maybe there was some software out there that booted into some kind of remote access server? When I tested it with a monitor (A friends) I set the BIOS to boot from USB so anything I can load onto a stick should boot. Ideas? Hacks?

• Processor speeds on my machine don't live up to manufacturer hype

  - by atch

  Why am I not seeing the promised speed claims of processor manufacturers on my computer? Producers of processors claim that their product can perform so many thousands (or millions) of operations per second. And yet on my machine (4GB, 3500hz), the typical program (Word, Visual Studio etc.) takes at least 10 seconds to start. I've formatted my hard drive and ticked all the necessary boxes to optimize my machine and yet I'm not seeing the promised speeds. Say it takes Outlook ten seconds to load. How many millions of operations does it really go through in order to start up?

• xDebug on Zend Server CE under Windows XP

  - by Hippyjim

  I have Zend Server installed on my Windows XP development machine, installed when I was naive and didn't know that Eclipse was going to become so suck so badly for PHP development. I've made the upgrade to Netbeans, but for debugging they only support xDebug. To be fair I've never used "proper" debuggers before, but other folks have raved about them so I thought I'd give it a try. I followed some directions on the Zend forum about how to install xDebug on Zend server, disabling Zend Debugger in the process. The xDebug "custom installation instructions" wizard tells me that my PHP was compiled with an unsupported compiler (MS VC8), and won't let me download anything. I tried a couple of the other xDebug binaries, but they just refused to load. So I'm left without a debugger option. Does anyone know how I can change the compiler of the php version I have installed so I can use a debugger in Netbeans? or how else i can get xDebug to install on Zend Server?

• How can I use Windows Firewall to only permit the Windows Update service to make an outbound connection?

  - by microsmash

  I'm trying to tailor my Windows Firewall settings (using the Windows Firewall with Advanced Security console) to only permit programs that need to access the Internet with an outbound connection to do so. This works fine for normal applications as I can just allow the program, but services that load in the svchost.exe process are a problem. The only services I actually need to give access to are Windows Update and the Background Intelligent Transfer Service (and even that, I would only like Windows Update to be able to submit jobs to, but that's another issue.) Is there a method to only allow these to be permitted an outbound connection, and not any of the other services loaded in svchost?

• Managing JS and CSS for a static HTML web application

  - by Josh Kelley

  I'm working on a smallish web application that uses a little bit of static HTML and relies on JavaScript to load the application data as JSON and dynamically create the web page elements from that. First question: Is this a fundamentally bad idea? I'm unclear on how many web sites and web applications completely dispense with server-side generation of HTML. (There are obvious disadvantages of JS-only web apps in the areas of graceful degradation / progressive enhancement and being search engine friendly, but I don't believe that these are an issue for this particular app.) Second question: What's the best way to manage the static HTML, JS, and CSS? For my "development build," I'd like non-minified third-party code, multiple JS and CSS files for easier organization, etc. For the "release build," everything should be minified, concatenated together, etc. If I was doing server-side generation of HTML, it'd be easy to have my web framework generate different development versus release HTML that includes multiple verbose versus concatenated minified code. But given that I'm only doing any static HTML, what's the best way to manage this? (I realize I could hack something together with ERB or Perl, but I'm wondering if there are any standard solutions.) In particular, since I'm not doing any server-side HTML generation, is there an easy, semi-standard way of setting up my static HTML so that it contains code like <script src="js/vendors/jquery.js"></script> <script src="js/class_a.js"></script> <script src="js/class_b.js"></script> <script src="js/main.js"></script> at development time and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <script src="js/entire_app.min.js"></script> for release?

• Intel mobile CPU power consumption at idle levels?

  - by Ivan Petrushev

  I was wondering if someone has observations (or specifications) of different mobile processors power consumption levels when idle? Let's define 'idle' with 'browsing web sites trough wifi, no flash, no multitasking'. There are different series processors, recognizable by their first letter. The letter tells about the maximum TDP. For example: T - 30-39W P - max 25W L - 12-19W U - <12W However this is about maximum consumptions during load. Is there any difference in power levels when the CPU is idling?

• How do I get my Lexmark x4650 printer working?

  - by Fallen Dohingy

  I think that my printer stopped working with the switch to gnome 3 or unity. Yes I have tried 32 and 64 bit os's. Here is the driver In order to actually install the driver, you need to extract it and then open up terminal and type sudo and then a space. Then drag the script into the terminal window. Here is what it said in the diver install window: Extracting file: printdriver.te Extracting file: lexmark-08z-series-driver-1.0-1.i386.deb Extracting file: launcher.c Extracting file: launcherfallendohingy@Ubuntu-Inspiron-15R:~$ sudo '/home/fallendohingy/Downloads/lexmark-08z-series-driver-1.0-1.i386.deb.sh' [sudo] password for fallendohingy: Verifying archive integrity...

• how can I effect DNS Caching on PHP/Memcache application

  - by Niro

  In a very high loaded Ubuntu/PHP web server I found that the PHP line: $memcache-connect("int-aws_ec2.memcached.myapp.net",11211); sometimes takes ~5 secs. Replacing the url with the ip address decreases the server load from ~20 to 0 My question is - where are the settings that effect the DNS caching for this? Is it in the server level or the memcache library ? How can I change it ? Additional info: Ubuntu 10.04 lucid PHP: 5.3.2-1ubuntu4.10 Apache/2.2.14 (Ubuntu) Amazon EC2 Even more info per Celada's comment: The DNS handling for the memcache server is done by scalr (the platform I use to manage the cloud resources). They have a client located on the instances and their own DNS servers. /etc/nsswitch.conf - hosts: files dns /etc/resolv.conf: nameserver 172.16.0.23 domain ec2.internal search ec2.internal The domain is not in hosts.conf To check if I run nscd I used /etc/init.d/nscd stop and received 'no such file' so i guess I dont run nscd. Thanks !

• My server is running out of memory, despite having all swap free

  - by Biohazard

  I am using Debian 6 (Squeeze). The server has 4gb of memory in it, and 8gb of swap. I'm starting to get memory alloc errors at high application load times, but from top command: Mem: 4055944k total, 3915436k used, 140508k free, 10444k buffers Swap: 7999480k total, 0k used, 7999480k free, 3604496k cached The system isn't even trying to use the swap? Why would this be happening? I would like to upgrade the primary memory, but this isn't possible just right now. Thanks.

• jQuery + Perl CGI to vb.net transition

  - by user1257458

  I've been developing oracle database-heavy "web applications" forever by building my html by hand, adding some jquery to handle ajax requests (html inserts for forms processing etc), and always did my server side stuff in perl cgi. I really love how easy it is to read some form input, execute some select statements through dbi (SO EASY), and generate HTML to be inserted by the jquery request. That's a web application to me. However, my new boss builds everything in visual studio 2010, vb.net, usually webforms. So, for work reasons, I now need to start developing in vb.net so it can be collectively maintained, and I'm just seeking advice on where to start learning/how to approach this. I know I could at least learn ASP.net and VB.net, and create a webform, have it read parameters, return HTML, etc. which would allow me to use my previously written HTML and client-side scripts (jQuery). Although- since we're moving heavily to mobile applications I really need to reduce client-side processing load. Is there any advantage to my boss' method? Thanks a ton.

• AWS Autoscaling issue with existing nodes in ELB

  - by Ram Prasad

  I already have a ELB setup called MyLoadBalancer. I already have 2 nodes running on it with health checks (that checks a URL on the node to see if they are up) Created an autoscaling group (min 2, Max 10) Associated launchconfig mylaunchconfig that provisions a node using an AMI Created a trigger, that checks for avg min connections of 100 and Max of 500 (checks the load balancer and it is support to increase the node count by 1, if avg connections are 500 and decrease by one if less than 100) as-create-or-update-trigger MyTrigger --auto-scaling-group MyAutoScalingGroup --namespace "AWS/ELB" --measure RequestCount --statistic Average --dimensions "LoadBalancerName=MyLoadBalancer" --period 60 --lower-threshold 500 --upper-threshold 800 --lower-breach-increment=-1 --upper-breach-increment=1 --breach-duration 600 Now the issue is, as soon as I put in the trigger, it start 2 nodes .... but there are already two nodes in the LB. So, why is it provisioning 2 more nodes, when the nodes are there ? is it because it is not recognizing the existing 2 nodes ? then how do I add the existing nodes to the AutoScaling group ?
