• How to implement Comet in database side?

  - by Morgan Cheng

  I have been searched for this question for a long time. How to implement Comet in database side? To support Comet, we'd better have a web server stack that supports asynchronous operation. So, Apache is not a option. There are some open source web server such as tornado can do asynchronous http handling. This is in web server level. In database level, how to make web server know that some event happens in database? There should be a asynchronous way to let web server know that something updated in database. Polling is not a option. Is there any example available?

• Entering Safe Mode problem

  - by NikolaysGS

  Hi! When i start my pc i get following message: The Logon User Interface DLL RtlGina2.dll failed to load I found solution here But i ca not log into my pc, neither in safe/normal mode. It is interesting that first time i succeed loging into safe mode, but change msconfig boot.ini to safemode with networking where i can not log in. And now every time no matter what i am choosing from F8 menu, i enter in safe mode with networking(where i get following error). So is it any way to log in back into "pure" safe mode. I am not sure that the question it`s clear enough ;-(

• HAProxy NGInx SSL setup

  - by Niclas

  I've been looking around different setups for a server cluster supporting SSL and I would like to benchmark my idea with you. Requirements: All servers in the cluster should be under the same full domain name. (http and https) Routing to subsystems is done on URI matching in HA proxy. All URIs have support for SSL support. Wish: Centralizing routing rules ---<----http-----<-- | | Inet -->HA--+---https--->NGInx_SSL_1..N | | +---http---> Apache_1..M | +---http---> NodeJS Idea: Configure HA to route all SSL traffic (mode=tcp,algorithm=Source) to an NGInx cluster turning https traffic into http. Re-pass the http traffic from NGInx to the HA for normal load-balancing which performs load balancing based on HA config. My question is simply: Is this the best way to to configure based on requirements above?

• How can you tell a USB cable version?

  - by Keltari

  Here is a question a student asked me in one of my A+ certification classes: How can you tell a USB cable version? I honestly dont know the answer, I cant find one either. USB cables are rated for versions 1, 1.1, 2, and now 3. I have seen their versions on the packaging, but never marked on the cable itself. Since the respective versions are manufactured differently, there is a difference between them. So, how can you tell? On Wikipedia: USB cables v.2 and earlier do use a "twisted pair" method, but doesnt specify if the cables themselves are the same or different. Is the cable rating system for v.2 and earlier just marketing hype?

• disable "SSL 2.0+ upgrade support" in nginx

  - by Bhargava

  I evaluated the SSL credentials of my server with qualsys ssl page ( https://www.ssllabs.com/ssldb/index.html ) and found the entry "SSL 2.0+ upgrade support" being marked as yes. I want to disable this sslv2 handshake too. I searched around and found http://forum.nginx.org/read.php?2,104032m, which points to creating a openssl.cnf file. Have a naive question here. After creating the file, does one need to re-key his certificate for this to work ? Are there any other steps to follow ? I use nginx 1.0.11 and openssl "OpenSSL 1.0.0e-fips 6 Sep 2011". I have set ssl_ciphers in nginx to SSLv3 TLSv1;

• Which are the most important directories to backup on a Linux server?

  - by QAH

  Hello everyone! I'm running an Ubuntu 9.10 Linux server. I'm trying to find a way to backup the machine while it is running and from what I see, this eliminates the disk clone utilities. All of the disk clone stuff I have seen for Linux requires that you reboot into a special live CD. So my question is this, what is the best solution for backing up the system while it is running? Also, I don't really care about the OS config too much, I just want to be able to keep my stored files and my programs that I have installed on it. Thanks

• Apache server doesn't create directory or file under www-data user [duplicate]

  - by Harkonnen

  This question already has an answer here: What permissions should my website files/folders have on a Linux webserver? 4 answers very newbie to Apache here I installed Apache 2.4 on my Arch server where I installed newznab (a newsgroups indexer). I have noticed that all files newznab needs to create are created under my login user, and not apache default user (www-data). I read here that it's bad security practice to allow www-data to write files. I agree. But as an apache newbie, I would like to know where (in the httpd.conf I suppose ?) the user allowed to write files can be configured, because I want another account to be allowed to write files instead of my main account.

• Is it possible to choose the Amazon Glacier Vault when backing up from Synology NAS?

  - by Jorrit Reedijk

  I am using Amazon Glacier Backup on a Synology NAS (rackstation). But the Synology backup software for glacier does not allow me to choose the vault to backup to. This means I can not give my own name to the vault, but also I can not backup to a previously created vault (I also have this problem now after replacing a Synology rackstation). Is there any way to choose to which vault you want your Synology to backup to? Edit: I have now posted this question to the Synology forum also: http://forum.synology.com/enu/viewtopic.php?f=174&t=86557&e=0 If I can solve the problem I'll post the solutions here also.

• Accurate Windows equivalent of the Unix which(1) command

  - by SamB

  It's easy enough to write a simple script that works like the which(1) command from unix, which searches for a given command along the PATH. Unfortunately, the CreateProcess function is not so simple, so this type of script does not give accurate results: CreateProcess looks in a number of directories not in the PATH, looks for files with all of the extensions listed in PATHEXT, etc. Worse, who knows what might be added in future versions of Windows? Anyway, my question is: is there a robust, accurate which(1) equivalent for Windows, which always tells you what file CreateProcess would find?

• CPU I/O communication

  - by b-gen-jack-o-neill

  Hi, I know there is this question already discussed, but I still don´t understand something, so please just help me clarify it. What I understand there is 2 way to do I/O aka communicate from CPU with other HW. One is to use in and out instructions, and second is the memory mapped. But what I don´t actually understand is, is IN and OUT instructions are used, you define source port. But what is this port? I mean, is it different set of pins on CPU or what? And, to what is that port connected? And for the memory mapped, I miss just a tiny detail. Wheather memory mapped I/O must be first set by IN and OUT instructions, or does the device actually somehow itself connects to the RAM and reads it? Thanks.

• How to quickly switch monitors on multi-monitor setup?

  - by Saxtus

  At my desktop PC, I have 3 displays hooked up on my Palit GeForce GTX 480 to extend my desktop: DVI: Samsung SyncMaster T220 (22" 16:10, 1680x1050, as my main) DVI: Samsung SyncMaster 940BF (19" 4:3, 1280x1024) HDMI: Sony Bravia KDL-32D3000 (32" 16:9, 1360x768) As expected, the GFX card can only utilize 2 of the displays at any given time, so I have to manually switch using Windows' "Display Properties" dialog, each time I want to switch between them. I've tried UltraMon, DisplayFusion and PowerStrip (so please don't refer me to a question where those are given as solutions) but they are unable to switch monitors. Instead they can only change display resolutions and settings on the existing active monitors, with specially weird results when I've saved the monitor states and then tried to switch monitors using the saved states! Any idea on how to bypass the awful "Display Properties" dialog and it's "confirm your change" timer?

• When my printer fails to print with only "printer error" as the message, how can I find details?

  - by lavinio

  Setup: Dell Latitude D620 in the docking station HP color laserjet 2550L Parallel cable Sometimes when I undock (and I do suspend before undocking and docking), when I reattach, the printer will not print. It simply says "error", with no description. Killing and restarting the spooler will not help, but rebooting will. There is nothing in the system event logs, nor does the print spooler window provide any details other than "error" My question is, when there is an error, is there any way to find out what is causing it to get stuck, so that I can "unstuck" it instead of rebooting?

• If I use openvpn, can vpn servers monitor my usernames/passwords?

  - by Duff

  Openvpn uses a type of encryption similar to ssl. This seems to suggest that even if I choose an incredibly shady VPN server, then my content will be secure. That is, the VPN server will be able to monitor what websites I patronize, but not the actual data I transfer. That said, I am not an expert at this type of thing. I wanted, therefore, to make sure that I understand correctly. Is it true that if I use openvpn that my username/passwords are secure, even if the VPN is untrustworthy? If not, why? (And how, if at all, can it be fixed?) Examples of things that I don't know much about that may (or may not! I honestly don't know much about this.) be related to my question are: DNS leakage, IPv6, tracking cookies, browser plugins and websites that don't support https.

• Xcode find in document stuck in case-sensitive

  - by mjdth

  When in Xcode editing code for my objective C files, I often press Command-F to bring up the little Find-In-Document banner across the top. Sometimes this gets stuck in case-sensitive search, and when it does that it also won't loop through the entire document and sometimes won't even display the selected found string. I can't find any options to turn off the case sensitivity, and I never intentionally turned it on. I've restarted xcode several times hoping that would be it but it's changed nothing. Slightly off-topic, but this was the best place I could think of to ask this question. Thanks for any response!

• Right Drag on Mac

  - by Mafuba

  How do you perform a right-click-drag operation on Mac hardware? I know you can right click, but there does not seem to be a right click drag gesture. In my specific case I am using a MacBook Pro, and I am in a Windows environment. The question is more than just theoretical. I ask because there is functionality that uses this gesture, at least in the Windows world. For example, right now I'm trying to do a copy and rename in the TortoiseSVN repository browser. I think there are things you can do with a right drag in graphical editors like Photoshop as well. In windows you get a context menu when you right drag files. For those familiar with the software, I know I can do it in other ways; I'm not looking for workarounds to specific problems.

• How to view bad blocks on mounted ext3 filesystem?

  - by Basilevs

  I've ran fsck -c on the (unmounted) partition in question a while ago. The process was unattended and results were not stored anywhere (except badblock inode). Now I'd like to get badblock information to know if there are any problems with the harddrive. Unfortunately, partition is used in the production system and can't be unmounted. I see two ways to get what I want: Run badblocks in read-only mode. This will probably take a lot of time and cause unnecessary bruden on the system. Somehow extract information about badblocks from the filesystem iteself. How can I view known badblocks registered in mounted filesystem?

• Using WebSphere CloudBurst with PowerVM to AIX virtualization over a cloud

  - by ADD Geek

  hi there we are studying the virtualization option to reduce our datacenter cost, and this research was assigned to me. we looked into alternatives and we almost reached a conclusion that PowerVM is the only option to virtualize pSeries servers. we found no signs of cloud support explicitly mentioned in any document, however there was the mention of CloudBurst. from the videos we watched and the documents we read, it seems that CloudBurst is more oriented towards Application Servers (WebSphere Software). but our environment is not relying only on WebSphere. we have some banking applications, Oracle Databases and MQ/Broaker. the question is: 1- can we virtualize the existing applications (all running AIX) on a cloud running on top of some of the existing servers? (given that we do the sizing properly) 2- is PowerVM to run on top of CloudBurst? 3- if the above solution is applicable, is this some sort of HA solution (since the VM will run on top of multiple physical boxes, while the same physical box will run multiple live images) thanks for your help

• How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

  - by moogeek

  Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

• Mod_rewrite not working on ISPConfig 3 Server

  - by Akahadaka

  Problem I recently migrated a Drupal site from a shared hosting server to my own VM. Everything appears to work correctly, except clean urls. My VM Setup Ubuntu 10.04 LAMP ISPConfig 3 What I've tried From reading up on a number of drupal forums I've tried the following in this order Check that mod_rewrite is installed and enabled Changed PHP from FastCGI to Mod_PHP (prefer to use FastCGI or suPHP though to avoid having tmp/files folders with 777 permissions) Changed the Redirect type to L in ISPConfig Sites-domain.com-Redirect Changed /etc/apache2/sites-enabled/000-default <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All ... </Directory> Not sure about points 3 and 4, I do want all domains to be able to use mod_rewrite out of the box. Question Have I done something wrong or am I missing a step? Ultimately I would like to use FastCGI and clean urls working on all ISPConfig 3 domains without having to make any changes to individual domain settings. Any ideas appreciated, I'll try them all.

• Automatic Excel Script

  - by Thomas

  I am a 6th year medical student and I'm working on my thesis. I have no experience with programming whatsoever, a friend recommended me to post my question here. I am strugling with the following problem: I have data of 400 patients, stored in 400 different excel files. Each file contains 34 columns in a specific order, let's say A to Z. The order is the same in each of these 400 files. Now I need to a make a new excel document that contains the first column of each patient. So I need all the first columns of my 400 different excel files, lined up next to each other in a new document. Preferebally in the form of a automatic script. After that I want to do the exact same thing but for the second column, then the third and so on. This is probably a problem that has already been solved. Otherwise could someone help me out? You have my thanks!

• Dummy HTTP server for debugging

  - by Andrea

  This is more or less the inverse of my previous question. I need to debug some HTTP requests that I am making. Since these requests arise from the use of some external libraries, sometimes I am not sure of what is the actual data I am sending. Is there some dummy server (for Linux) that accepts HTTP requests and just prints them somewhere so that I can inspect them? I would like to be able to see in plain text the full request, like POST /foo HTTP/1.1 Host: www.example.com Accept: text/xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-gb,en;q=0.5 Content-Type: text/plain Content-Length: 11 Hello world

  Hello. I've a question: (I sent it in past) I have multipart rar file. Their contents are: file.part01.rar: myfolder (is a folder) data.cab -- file.part02.rar: myfolder (is a folder) data.cab <- file.part03.rar: myfolder (is a folder) data.cab <- file.part04.rar: difffolder (is a folder) anfolder (is a folder) data.cab <- file.part05.rar: myfolder (is a folder) data.cab <-- I want to extract it, so I right-click on "file.part01.rar" and select "Extract to ...". It extract 3 files, but in part 4, WinRAR said: "CRC. This file is currput." I think it problem is in the folders name in part04.rar. Is there anyway to rename folders in part04.rar? and cut "data.cab" from "afolder" to "difffolder". I really need it!! it is very emergency!!!!!!!! Thank you .....

• conditional formatting in excel 2010

  - by bigMir

  I have some strange problem, after I've made switch from excel 2007 to excel 2010 I've started to receive duplicates of conditional formatting rules in excel. For example: I have conditional formatting which colors the cell when it detects that cell contains a word "hello". When I copy this cell to other cells (which also contains the same rule) sometimes I receive duplicates. Those duplicates really slows down excel. So my question is: is there any possiblity to disable copy/paste of conditional formatting (I want to copy/paste all content excep conditional formatting, all formulas values and other stuff). P.S. Just to make it clear, I don't know how to reporduce that problem, it occurs sometimes and I work with excel a lot

• How to execute a shell script on startup?

  - by vijay.shad

  I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac
