• Scoping a home dev server

  - by AbhikRK

  Hi. I’m looking to build a multi-purpose home development server. In this post, I’m looking to outline what I want from such a system, and the ‘why’s of it, to some limited extent, and finally, some rudiments of how I’m looking to go about that. I’m mostly a developer, with just about some sysadmin familiarity. So, please excuse, correct me, and suggest on any ignorance which would come across in the following ;-) It will serve the following goals to start with:- NAS (Looking at using ZFS) Source control repo e.g Git server Database e.g MySQL server Continuous Integration e.g Hudson server Other stuff as and when they come up e.g RabbitMQ etc A development sandbox to play around with new stuff I want to achieve a high uptime for 2-5 as much as possible. They should run as independent services and with minimal maintenance. (e.g TurnKey Linux appliances) I’m thinking of running them as individual Xen DomUs. Then, maybe the NAS can be a Dom0 and 6 can be another DomU. The User for this would be mostly me. I can see 2-4 being sometimes used by 2-3 users, but that would be infrequent. I’m looking for a repeatable setup. Ideally I’d like to automate this setup through Chef or Puppet or something similar. Once everything runs, I want to be able to ssh/screen/tmux into 1-6 from my laptop or any other computer on the LAN/on-the-go. My queries are:- Is putting 1-6, all of them on a single box, a good idea? If so, what kind of hardware should I be looking at, for a low-cost, low-power setup? Although not at present, but in future I might be looking at adding audio/media servers to the mix. Would that impact the answers to 1? I have an old Pentium 3 and 810e motherboard combination. Is there any way I could put it to use? I had a look at the Sheevaplug, and was wondering if I could split off the NAS on its own using that. But ruled it out preliminarily due to its reported heating issues. Is it something i should still consider? Thanks in advance Have posted this question previously on SuperUser but no responses yet. So was wondering if this is a more apt forum for this.

• ffmpeg video4linux2 at specified resolution

  - by wim

  When I'm trying to record a clip from my webcam, using: ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 /tmp/spam.avi I get annoying problem with very low resolution video, and there is a message from ffmpeg saying: [video4linux2,v4l2 @ 0x2bff3e0] The V4L2 driver changed the video from 800x600 to 176x144 I have tried not specifying -s, or trying other sizes like 800x600, and always it forces me back to 176x144. Why is this and how can I prevent it? My webcam is one of those Logitech 9000 Pro, I know it supports better resolutions than this and I can see with v4l2-ctl --list-formats-ext that it goes up to at least 800x600. edit: complete console output follows wim@wim-desktop:~$ ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 /tmp/spam.avi ffmpeg version git-2012-11-20-70c0f13 Copyright (c) 2000-2012 the FFmpeg developers built on Nov 21 2012 00:09:36 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --enable-gpl --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3 libavutil 52. 8.100 / 52. 8.100 libavcodec 54. 73.100 / 54. 73.100 libavformat 54. 37.100 / 54. 37.100 libavdevice 54. 3.100 / 54. 3.100 libavfilter 3. 23.101 / 3. 23.101 libswscale 2. 1.102 / 2. 1.102 libswresample 0. 17.100 / 0. 17.100 libpostproc 52. 2.100 / 52. 2.100 [video4linux2,v4l2 @ 0x37a33e0] The V4L2 driver changed the video from 640x480 to 176x144 [video4linux2,v4l2 @ 0x37a33e0] Estimating duration from bitrate, this may be inaccurate Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 37066.740548, bitrate: 6082 kb/s Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 176x144, 6082 kb/s, 15 tbr, 1000k tbn, 15 tbc File '/tmp/spam.avi' already exists.

• Apache Alias subfolder and starting with dot

  - by MauricioOtta

  I have a multi purpose server running ArchLinux that currently serves multiple virtual hosts from /var/www/domains/EXAMPLE.COM/html /var/www/domains/EXAMPLE2.COM/html I deploy those websites (mostly using Kohana framework) using a Jenkins job by checking out the project, removes the .git folder and ssh-copy the tar.gz to /var/www/domains/ on the server and untars it. Since I don't want to have to re-install phpMyAdmin after each deploy, I decided to use an alias. I would like the alias to be something like /.tools/phpMyAdmin/ so I could have more "tools" later if I wanted to. I have tried just changing the default httpd-phpmyadmin.conf that was installed by following the official WIKI: https://wiki.archlinux.org/index.php/Phpmyadmin Alias /.tools/phpMyAdmin/ "/usr/share/webapps/phpMyAdmin" <Directory "/usr/share/webapps/phpMyAdmin"> AllowOverride All Options FollowSymlinks Order allow,deny Allow from all php_admin_value open_basedir "/var/www/:/tmp/:/usr/share/webapps/:/etc/webapps:/usr/share/pear/" </Directory> Changing only that, doesn't seem to work with my current setup on the server, and apache forwards the request to the framework which 404s (as there's no route to handle /.tools/phpAdmin). I have Mass Virtual hosting enable and setup like this: # # Use name-based virtual hosting. # NameVirtualHost *:8000 # get the server name from the Host: header UseCanonicalName On # splittable logs LogFormat "%{Host}i %h %l %u %t \"%r\" %s %b" vcommon CustomLog logs/access_log vcommon <Directory /var/www/domains> # ExecCGI is needed here because we can't force # CGI execution in the way that ScriptAlias does Options FollowSymLinks ExecCGI AllowOverride All Order allow,deny Allow from all </Directory> RewriteEngine On # a ServerName derived from a Host: header may be any case at all RewriteMap lowercase int:tolower ## deal with normal documents first: # allow Alias /icons/ to work - repeat for other aliases RewriteCond %{REQUEST_URI} !^/icons/ # allow CGIs to work RewriteCond %{REQUEST_URI} !^/cgi-bin/ # do the magic RewriteCond %{SERVER_NAME} ^(www\.|)(.*) RewriteRule ^/(.*)$ /var/www/domains/${lowercase:%2}/html/$1 ## and now deal with CGIs - we have to force a MIME type RewriteCond %{REQUEST_URI} ^/cgi-bin/ RewriteRule ^/(.*)$ /var/www/domains/${lowercase:%{SERVER_NAME}}/cgi-bin/$1 [T=application/x-httpd-cgi] There is also nginx running on this server on port 80 as a reverse proxy for Apache: location ~ \.php$ { proxy_pass http://127.0.0.1:8000; } Everything else was setup by following the official WIKI so I don't think those would cause trouble. Do I need to have the alias for phpMyAdmin setup along the mass virtual hosting or can it be in a separate include file for that alias to work?

• How do you splice out a part of an xvid encoded avi file, with ffmpeg? (no problems with other files

  - by yegor

  Im using the following command, which works for most files, except what seems to be xvid encoded ones /usr/bin/ffmpeg -sameq -i file.avi -ss 00:01:00 -t 00:00:30 -ac 2 -r 25 -copyts output.avi So this should basically splice out 30 seconds of video + audio, starting from 1 minute mark.

• Matlab cell length

  Ok I seem to have got the most of the problem solved, I just need an expert eye to pick my error as I am stuck.

• Is Abstract Factory Pattern implemented correctly for given scenario.... ???

  - by Amit

  First thing... I am novice to pattern world, so correct me if wrong anywhere Scenario: There are multiple companies providing multiple products of diff size so there are 3 entities i.e. Companies, Their Product and size of product I have implement Abstract Pattern on this i.e. so that I will create instance of IProductFactory interface to get desired product... Is below implementation of Abstract Factory Pattern correct ??? If not then please correct the approach + Also tell me if any other pattern can be used for such scenario Thanks in advance... public enum Companies { Samsung = 0, LG = 1, Philips = 2, Sony = 3 } public enum Product { PlasmaTv = 0, DVD = 1 } public enum ProductSize { FortyTwoInch, FiftyFiveInch } interface IProductFactory { IPhilips GetPhilipsProduct(); ISony GetSonyProduct(); } interface ISony { string CreateProducts(Product product, ProductSize size); } interface IPhilips { string CreateProducts(Product product, ProductSize size); } class ProductFactory : IProductFactory { public IPhilips GetPhilipsProduct() { return new Philips(); } public ISony GetSonyProduct() { return new Sony(); } } class Philips : IPhilips { #region IPhilips Members public string CreateProducts(Product product, ProductSize size) {// I have ingnore size for now.... string output = string.Empty; if (product == Product.PlasmaTv) { output = "Plasma TV Created !!!"; } else if (product == Product.DVD) { output = "DVD Created !!!"; } return output; } #endregion } class Sony : ISony {// I have ingnore size for now.... #region ISony Members public string CreateProducts(Product product, ProductSize size) { string output = string.Empty; if (product == Product.PlasmaTv) { output = "Plasma TV Created !!!"; } else if (product == Product.DVD) { output = "DVD Created !!!"; } return output; } #endregion } IProductFactory prodFactory = new ProductFactory(); IPhilips philipsObj = prodFactory.GetPhilipsProduct(); MessageBox.Show(philipsObj.CreateProducts(Product.DVD, ProductSize.FortyTwoInch)); or //ISony sonyObj = prodFactory.GetSonyProduct(); //MessageBox.Show(sonyObj.CreateProducts(Product.DVD, ProductSize.FortyTwoInch));

• $PATH is driving me nuts

  - by Chris4d

  OK, apologies if this is something dumb, but I'm running out of ideas. Goal: prepend /usr/local/bin to $PATH Problem: $PATH won't do what I want or expect How I got here: I want to start learning to program, so I'm getting comfortable messing around under the hood, but don't have a lot of experience. I installed the fish shell (because it's friendly!) using homebrew and set it as my default shell (under system prefs>users & groups>advanced). At some point, I ran brew doctor to see if my installs were all kosher, and it suggested I move /usr/local/bin to the front of $PATH so that I could use my installation of git rather than the system copy. Fine - but between path_helper and fish, something was happening to $PATH that was out of my control, and I could never get the paths arranged in the right way. Environment: OSX 10.8.2, upgraded from 10.7ish, with xcode and devtools installed, plus x11, homebrew, and fish More info: I've set my user's default shell back to bash, and tried a variety of shells thru terminal.app - bash, fish, sh. I moved /usr/local/bin to the top of /etc/paths but it didn't change anything. I looked thru the various config.fish files and commented out stuff that might mess with $PATH, didn't help. I have the following files in /etc/paths.d/: ./10-homebrew containing /usr/local/bin ./20-fish containing /usr/local/Cellar/fish/1.23.1/bin ./40-XQuartz containing /opt/X11/bin I added set +x to my profile and when I start terminal.app I get: Last login: Mon Oct 1 13:31:06 on ttys000 + '[' -x /usr/libexec/path_helper ']' + eval '/usr/libexec/path_helper -s' ++ /usr/libexec/path_helper -s PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/Cellar/fish/1.23.1/bin:/opt/X11/bin"; export PATH; + '[' /bin/bash '!=' no ']' + '[' -r /etc/bashrc ']' + . /etc/bashrc ++ '[' -z '\s-\v\$ ' ']' ++ PS1='\h:\W \u\$ ' ++ shopt -s checkwinsize ++ '[' Apple_Terminal == Apple_Terminal ']' ++ '[' -z '' ']' ++ PROMPT_COMMAND='update_terminal_cwd; ' ++ update_terminal_cwd ++ local 'SEARCH= ' ++ local REPLACE=%20 ++ local PWD_URL=file://Chriss-iMac.local/Users/c4 ++ printf '\e]7;%s\a' file://Chriss-iMac.local/Users/c4 Chriss-iMac:~ c4$ So it looks like path_helper runs, but then running echo $PATH nets me /usr/bin:/bin:/usr/sbin:/sbin. So, it looks like path_helper isn't even doing what it's supposed to anymore? I'm sure there is some well-defined behavior here that I don't understand, or I borked something while trying to fix it. Please help!

• VIM "upgraded" to expandtab and tabstop=8 on Python files

  - by dotancohen

  After reinstalling my OS from Kubuntu 12.10 to Kubuntu 14.04, VIM has changed its behaviour when editing Python files. Though before the reinstall all file types had noexpandtab and tabstop=4 set, now in Python those values are expandtab and tabstop=8, checked also via VIM behaviour and also via asking VIM set foo?. Non-Python files retain the noexpandtab and tabstop=4 behaviour that I prefer. The .vim direcotry and .vimrc were not touched during the reinstall. It can be seen that no files in .vimrc have been touched in months (with the exception of the irrelevant .netrwhist): - bruno():~$ ls -lat ~/.vim total 68 drwxr-xr-x 85 dotancohen dotancohen 12288 Aug 25 13:00 .. drwxr-xr-x 12 dotancohen dotancohen 4096 Aug 21 11:11 . -rw-r--r-- 1 dotancohen dotancohen 268 Aug 21 11:11 .netrwhist drwxr-xr-x 2 dotancohen dotancohen 4096 Mar 6 18:31 plugin drwxr-xr-x 2 dotancohen dotancohen 4096 Mar 6 18:31 doc drwxrwxr-x 2 dotancohen dotancohen 4096 Nov 29 2013 syntax drwxrwxr-x 2 dotancohen dotancohen 4096 Nov 29 2013 ftplugin drwxr-xr-x 4 dotancohen dotancohen 4096 Nov 29 2013 autoload drwxrwxr-x 5 dotancohen dotancohen 4096 May 27 2013 after drwxr-xr-x 2 dotancohen dotancohen 4096 Nov 1 2012 spell -rw------- 1 dotancohen dotancohen 138 Aug 14 2012 .directory -rw-rw-r-- 1 dotancohen dotancohen 190 Jul 3 2012 .VimballRecord drwxrwxr-x 2 dotancohen dotancohen 4096 May 12 2012 colors drwxrwxr-x 2 dotancohen dotancohen 4096 Mar 16 2012 mytags drwxrwxr-x 2 dotancohen dotancohen 4096 Feb 14 2012 keymap Though .vimrc has been touched since the reinstall, it was only me testing to see where the problem is.

• Using XmlDiffPatch when writing to stream

  - by Mark Smith

  I am trying to use xmldiffpatch when comparing two Xmls(one from a stream, the other from a file) and writing the diff patch to a stream. The first method is to write my xml to a memory stream. The second method loads an xml from a file and creates a stream for the patched file to be written into. The third method actually compares the two files and writes the third.

• Rails /tmp/cache/assets permissions issue using Debian virtual machine hosted on OS X Lion

  - by Jim

  I am running Parallels Desktop 7 on OS X Lion. I have a VM with Debian installed, and inside that VM I setup a Rails development environment. I am using Parallels Tools to share out my OS X home directory to the VM - the goal here is to run the Rails server on the VM, but host the files on OS X (so they are automatically backed up, and so I can use tools like Textmate to develop with). Everything seems to work with the shared directory - my Debian user can read, write, and execute files. However, when I cloned a recent Rails project from Git, I got an error message when it tried to compile the CSS assets. My symptoms are exactly the same as in the question: http://stackoverflow.com/questions/7556774/rails-sprocket-error-compiling-css-assest-chown-issue I believe this is permissions-based, but it is really weird. My entire Rails project directory has permissions set to 777 and my Debian user owns it. If I navigate into /tmp/cache/assets, those permissions are the same. However, the three-character directories Rails is creating (DCE, DA1, D05, etc...) are being created without write permissions! If I refresh the Rails page a few times, about 4 or 5 (with Rails creating new three-character directories every time), eventually it will create one of the directories with the proper 777 permissions and everything will work! This will persist until I make a change to the CSS files and it has to recompile. Does anyone have any idea what might be going on here? I can't fathom why it is creating temp directories with incorrect permissions, or why after a few refreshes the good permissions kick in and it works... It definitely seems to be an issue with the share, since if I move the project into a different directory on the VM, it seems to work fine. On the OS X side, I've given the shared folder 777 permissions as well, but no dice...any ideas? Update I've found that the number of times I need to refresh before it works is not random - it has to do with how many assets are being compiled. For example, if I edit one of my CSS files, and there are four CSS files in the app/assets/stylesheets directory, I have to refresh four times before the app will finally work without the operation not permitted error...

• .htaccess ignored, SPECIFIC to EC2 - not the usual suspects

  - by tedneigerux

  I run 8-10 EC2 based web servers, so my experience is many hours, but is limited to CentOS; specifically Amazon's distribution. I'm installing Apache using yum, so therefore getting Amazon's default compilation of Apache. I want to implement canonical redirects from non-www (bare/root) domain to www.domain.com for SEO using mod_rewrite BUT MY .htaccess FILE IS CONSISTENTLY IGNORED. My troubleshooting steps (outlined below) lead me to believe it's something specific to Amazon's build of Apache. TEST CASE Launch a EC2 Instance, e.g. Amazon Linux AMI 2013.03.1 SSH to the Server Run the commands: $ sudo yum install httpd $ sudo apachectl start $ sudo vi /etc/httpd/conf/httpd.conf $ sudo apachectl restart $ sudo vi /var/www/html/.htaccess In httpd.conf I changed the following, in the DOCROOT section / scope: AllowOverride All In .htaccess, added: (EDIT, I added RewriteEngine On later) RewriteCond %{HTTP_HOST} ^domain\.com$ [NC] RewriteRule ^/(.*) http://www.domain.com/$1 [R=301,L] Permissions on .htaccess are correct, AFAI can tell: $ ls -al /var/www/html/.htaccess -rwxrwxr-x 1 git apache 142 Jun 18 22:58 /var/www/html/.htaccess Other info: $ httpd -v Server version: Apache/2.2.24 (Unix) Server built: May 20 2013 21:12:45 $ httpd -M Loaded Modules: core_module (static) ... rewrite_module (shared) ... version_module (shared) Syntax OK EXPECTED BEHAVIOR $ curl -I domain.com HTTP/1.1 301 Moved Permanently Date: Wed, 19 Jun 2013 12:36:22 GMT Server: Apache/2.2.24 (Amazon) Location: http://www.domain.com/ Connection: close Content-Type: text/html; charset=UTF-8 ACTUAL BEHAVIOR $ curl -I domain.com HTTP/1.1 200 OK Date: Wed, 19 Jun 2013 12:34:10 GMT Server: Apache/2.2.24 (Amazon) Connection: close Content-Type: text/html; charset=UTF-8 TROUBLESHOOTING STEPS In .htaccess, added: BLAH BLAH BLAH ERROR RewriteCond %{HTTP_HOST} ^domain\.com$ [NC] RewriteRule ^/(.*) http://www.domain.com/$1 [R=301,L] My server threw an error 500, so I knew the .htaccess file was processed. As expected, it created an Error log entry: [Wed Jun 19 02:24:19 2013] [alert] [client XXX.XXX.XXX.XXX] /var/www/html/.htaccess: Invalid command 'BLAH BLAH BLAH ERROR', perhaps misspelled or defined by a module not included in the server configuration Since I have root access on the server, I then tried moving my rewrite rule directly to the httpd.conf file. THIS WORKED. This tells us several important things are working. $ curl -I domain.com HTTP/1.1 301 Moved Permanently Date: Wed, 19 Jun 2013 12:36:22 GMT Server: Apache/2.2.24 (Amazon) Location: http://www.domain.com/ Connection: close Content-Type: text/html; charset=UTF-8 HOWEVER, it is bothering me that it didn't work in the .htaccess file. And I have other use cases where I need it to work in .htaccess (e.g. an EC2 instance with named virtual hosts). Thank you in advance for your help.

• My VPS ubuntu server is very slow

  - by askmike

  I just installed a frech copy of Ubuntu 12.04 on my vps because my old installation was very slow, unfortunately this did not fix the problem. With slow I mean requests for my PHP websites take a long time, very slow (30 sec per request) to slow (3+ sec per request). When it's really bad SSH is also laggish. The websites are: askmike.org (pretty standard Wordpress) mvr.me (own PHP) slow? very slow: Here is a picture of loading a clean install of wordpress slow: here is a picture of loading a small PHP based website the vps The VPS has 256mb ram and an 25GB hdd. Besides serving the 2 small websites it isn't doing anything AFAIK. What have I installed Clean Ubuntu server 12.04 LAMP stack few things like git and nodejs (not using both) ossec (because I thought my server was getting hammered) munin What I already tried / done I installed munin so that I could watch io speed and such. The problem is that I don't know where to look for in the munin report. I checked logs and don't see anything strange (although I don't really know where to look for besides strange / repetitive errors and GET requests). I configured Apache MPM to: <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 40 MaxRequestsPerChild 0 </IfModule> (apache is using prefork, the default) Stats I copied the munin report as it appeared at 4:50 last night to a site hosted on a shared webhost. Note that tonight my mysql crashed somewhere after 1:00 (which is a new problem altogether), so therefor the graph for last night might look strange. Can anyone help me get my VPS up to normal speed? EDIT: Thanks for the replies. The VPS is 10 bucks a month and is from directvps.nl (Dutch host and I'm also dutch). I did two speed tests for disk IO: $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 23.1506 s, 46.4 MB/s $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 39.3796 s, 27.3 MB/s Anyway: how can I prove to my VPS host that it is to slow? I can understand a server being busy slowing a website down. But 5-30 sec loadtime for a normal PHP webpage?

• OpenSSH (Windows) does not forward X11

  - by Shulhi Sapli

  I'm running Ubuntu 13.04 in VM and I wanted to do X11 forwarding to my host (Win 8), so far it works fine using PuTTY and XMing server for Windows. But I am curious why it doesn't work if I use OpenSSH binaries (it comes together with Git for windows). This is what I've done so far: ssh -X [email protected] (also tried with -Y) then gedit but received error of Cannot open display. echo $DISPLAY came out as empty. So, I try to export DISPLAY=localhost:0.0 but it still won't work. The DISPLAY environment that I set is exactly as when it runs with Putty. I also try changing the DISPLAY to 192.168.2.3:0.0 and other display number as well, but still it won't work. Of course I could just use Putty to make it work, but I was wondering why OpenSSH binaries does not work. I have enabled all settings required in both /etc/ssh/ssh_config and /etc/ssh/sshd_config. If I run with -v option, this is what I get F:\SkyDrive\Projects> ssh -X -v [email protected] OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to 192.168.2.3 [192.168.2.3] port 22. debug1: Connection established. debug1: identity file /c/Users/Shulhi/.ssh/identity type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_rsa type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.1p1 Debian-4 debug1: match: OpenSSH_6.1p1 Debian-4 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '192.168.2.3' is known and matches the RSA host key. debug1: Found key in /c/Users/Shulhi/.ssh/known_hosts:2 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/Shulhi/.ssh/identity debug1: Trying private key: /c/Users/Shulhi/.ssh/id_rsa debug1: Next authentication method: password [email protected]'s password: It seems that there is no request for X11 (I'm not sure if there is should be one too here).

• ffmpeg - join / merge on top of each other

  - by AisIceEyes

  I'm trying to join together two videos on top of each other. I already did these two ffmpeg commands ffmpeg -i 2_Out_of_Control.VOB -aspect 16:9 \ -vf "yadif=0:-1:0,crop=w=714:h=476:x=6:y=0,scale=1280:720,boxblur=lp=13" \ -c:v libx264 -preset medium \ -c:a copy \ '2(blurred)Out_of_Control.mp4' ffmpeg -i 2_Out_of_Control.VOB \ -vf "yadif=0:-1:0,crop=w=714:h=476:x=6:y=0,scale=1080:720" \ -c:v libx264 -preset medium \ -c:a copy \ '2(clear)Out_of_Control.mp4' I'm currently stuck on making the "clear" version on top of the "blurred" version. I'm not sure how to do that. Can anybody help please? Been googling for around 2 days already. Only achieved it by using OpenShot but yeah, would prefer if there is an ffmpeg command to merge the two videos on top of each other.

• Javascript returns Nan in IE, FF ok

  - by user350184

  im very new to javascript, and writing this script to add up a shopping cart and print out subtotals and totals. it works in FF but not in IE. this function is called by onclick of one of three select options with a value of 0-25. it is in a js file called in the head. what it does is get the selected values as variables, parseint them, adds and multiplies, and changes the innerHTML of the table to reflect the subtotals, and total. FF does it great, but IE gives Nan. ive tried rewriting it a number of different ways, and many translations still work in FF but not IE8. ive made sure the variables and form id's arent repeated. function gen_invoice() { var scount = parseInt(document.shopcart.studentcount.value, 10); var ycount = parseInt(document.shopcart.youthcount.value, 10); var fcount = parseInt(document.shopcart.facultycount.value, 10); //html output source is 3 selects like this, with diff ids and names: //<select name="studentcount" id="studentcount"> //<option onclick="gen_invoice()" value="0">0 </option></select> var cardcost = parseInt(document.shopcart.cardprice.value, 10); //cardcost comes from hidden input value: //<input type="hidden" id="cardprice" name="cardprice" value="25"> var totalsum = scount + ycount + fcount; var grandtotal = totalsum * cardcost; document.getElementById('s_price').innerHTML = scount * cardcost; document.getElementById('y_price').innerHTML = ycount * cardcost; document.getElementById('f_price').innerHTML = fcount * cardcost; document.getElementById('grand').innerHTML = grandtotal; //.... } ...after this there are 3 long loops for writing out some other forms, but they dont work in IE either because they depend on the selected values to be an integer. this part happens first and returns Nan, so im sure the problem is here somwhere. I have literally hit my head on the table over this. You can imagine how frustrating it is to be able to write the entire rest of the site beautifully, but then fail at adding 3 numbers together. help please!

• What server setup for a small web development company? [closed]

  - by Giordano

  I co-own a company with a friend of mine and we have decided to buy a new server to support our business (our current server is an Asus EEE Box, working great but too limited :) ). I should mention that we are web developers but occasionally we do small-office sys admin. Thus, 99% of time we work on GNU/Linux (mainly Ubuntu) but from time to time we need to setup a Windows environment to assist some customers (e.g. setup a temporary SQL Server 2008). Our requirements: Low budget: we don't want the cheapest solution out there but we can't afford to spend too much. Budget could be ~1000-1500€ (before VAT) Robustness: we would like to setup a RAID array and maybe have an external disk where we can store backups Virtualization: we need to be able to setup few servers for development. The scenario is something like this (~8 appliances running in parallel): Redmine + GIT server Bacula server FTP server 3-4 virtual appliances that could be set up on demand to test our applications or support a customer. The appliances could be: LAMP, Tomcat+PostgreSQL, SQL Server Support: if something breaks down it shouldn't be too difficult to find a replacement. Now, given the main requirements, there are some doubts we need to clarify: Do you suggest to buy a prepackaged solution (for example a customized Dell PowerEdge T110 or T310) or to assemble the server by ourselves (buy the separate components)? What RAID configuration do you suggest? I was thinking of RAID1 (probably cheaper) or RAID5. should we buy a hardware RAID controller or is it ok to use a software RAID (mdadm)? In case, which controller do you suggest? What processor do you suggest (Intel Xeon, i3, i5, i7, AMD)? How much RAM? (I was thinking at least 8GB, ~1GB per appliance) What virtualization software do you recommend? VMWare seems to be the best choice, but what about XEN or KVM? We don't want to buy licenses at the moment so we would like to consider only free options. What OS do you recommend? We know Ubuntu, Debian, Gentoo very well (we would like to use Ubuntu Server), however it seems a lot of people goes for CentOS. Thanks in advance if you can help us with this! It's our first "serious" server so many doubts popped up :) Please feel free to add further recommendations if you have some to share ;) Have a nice day

• Enable Automatic Code First Migrations On SQL Database in Azure Web Sites

  - by Steve Michelotti

  Now that Azure supports .NET Framework 4.5, you can use all the latest and greatest available features. A common scenario is to be able to use Entity Framework Code First Migrations with a SQL Database in Azure. Prior to Code First Migrations, Entity Framework provided database initializers. While convenient for demos and prototypes, database initializers weren’t useful for much beyond that because, if you delete and re-create your entire database when the schema changes, you lose all of your operational data. This is the void that Migrations are meant to fill. For example, if you add a column to your model, Migrations will alter the database to add the column rather than blowing away the entire database and re-creating it from scratch. Azure is becoming increasingly easier to use – especially with features like Azure Web Sites. Being able to use Entity Framework Migrations in Azure makes deployment easier than ever. In this blog post, I’ll walk through enabling Automatic Code First Migrations on Azure. I’ll use the Simple Membership provider for my example. First, we’ll create a new Azure Web site called “migrationstest” including creating a new SQL Database along with it:   Next we’ll go to the web site and download the publish profile:   In the meantime, we’ve created a new MVC 4 website in Visual Studio 2012 using the “Internet Application” template. This template is automatically configured to use the Simple Membership provider. We’ll do our initial Publish to Azure by right-clicking our project and selecting “Publish…”. From the “Publish Web” dialog, we’ll import the publish profile that we downloaded in the previous step:   Once the site is published, we’ll just click the “Register” link from the default site. Since the AccountController is decorated with the [InitializeSimpleMembership] attribute, the initializer will be called and the initial database is created.   We can verify this by connecting to our SQL Database on Azure with SQL Management Studio (after making sure that our local IP address is added to the list of Allowed IP Addresses in Azure): One interesting note is that these tables got created with the default Entity Framework initializer – which is to create the database if it doesn’t already exist. However, our database did already exist! This is because there is a new feature of Entity Framework 5 where Code First will add tables to an existing database as long as the target database doesn’t contain any of the tables from the model. At this point, it’s time to enable Migrations. We’ll open the Package Manger Console and execute the command: PM> Enable-Migrations -EnableAutomaticMigrations This will enable automatic migrations for our project. Because we used the "-EnableAutomaticMigrations” switch, it will create our Configuration class with a constructor that sets the AutomaticMigrationsEnabled property set to true: 1: public Configuration() 2: { 3: AutomaticMigrationsEnabled = true; 4: } We’ll now add our initial migration: PM> Add-Migration Initial This will create a migration class call “Initial” that contains the entire model. But we need to remove all of this code because our database already exists so we are just left with empty Up() and Down() methods. 1: public partial class Initial : DbMigration 2: { 3: public override void Up() 4: { 5: } 6: 7: public override void Down() 8: { 9: } 10: } If we don’t remove this code, we’ll get an exception the first time we attempt to run migrations that tells us: “There is already an object named 'UserProfile' in the database”. This blog post by Julie Lerman fully describes this scenario (i.e., enabling migrations on an existing database). Our next step is to add the Entity Framework initializer that will automatically use Migrations to update the database to the latest version. We will add these 2 lines of code to the Application_Start of the Global.asax: 1: Database.SetInitializer(new MigrateDatabaseToLatestVersion<UsersContext, Configuration>()); 2: new UsersContext().Database.Initialize(false); Note the Initialize() call will force the initializer to run if it has not been run before. At this point, we can publish again to make sure everything is still working as we are expecting. This time we’re going to specify in our publish profile that Code First Migrations should be executed:   Once we have re-published we can once again navigate to the Register page. At this point the database has not been changed but Migrations is now enabled on our SQL Database in Azure. We can now customize our model. Let’s add 2 new properties to the UserProfile class – Email and DateOfBirth: 1: [Table("UserProfile")] 2: public class UserProfile 3: { 4: [Key] 5: [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] 6: public int UserId { get; set; } 7: public string UserName { get; set; } 8: public string Email { get; set; } 9: public DateTime DateOfBirth { get; set; } 10: } At this point all we need to do is simply re-publish. We’ll once again navigate to the Registration page and, because we had Automatic Migrations enabled, the database has been altered (*not* recreated) to add our 2 new columns. We can verify this by once again looking at SQL Management Studio:   Automatic Migrations provide a quick and easy way to keep your database in sync with your model without the worry of having to re-create your entire database and lose data. With Azure Web Sites you can set up automatic deployment with Git or TFS and automate the entire process to make it dead simple.

• Your thoughts on Best Practices for Scientific Computing?

  - by John Smith

  A recent paper by Wilson et al (2014) pointed out 24 Best Practices for scientific programming. It's worth to have a look. I would like to hear opinions about these points from experienced programmers in scientific data analysis. Do you think these advices are helpful and practical? Or are they good only in an ideal world?

(b) Use pair programming when bringing someone new up to speed and when tackling particularly tricky problems. (c) Use an issue tracking tool. I'm relatively new to serious programming for scientific data analysis. When I tried to write code for pilot analyses of some of my data last year, I encountered tremendous amount of bugs both in my code and data. Bugs and errors had been around me all the time, but this time it was somewhat overwhelming. I managed to crunch the numbers at last, but I thought I couldn't put up with this mess any longer. Some actions must be taken. Without a sophisticated guide like the article above, I started to adopt "defensive style" of programming since then. A book titled "The Art of Readable Code" helped me a lot. I deployed meticulous input validations or assertions for every function, renamed a lot of variables and functions for better readability, and extracted many subroutines as reusable functions. Recently, I introduced Git and SourceTree for version control. At the moment, because my co-workers are much more reluctant about these issues, the collaboration practices (8a,b,c) have not been introduced. Actually, as the authors admitted, because all of these practices take some amount of time and effort to introduce, it may be generally hard to persuade your reluctant collaborators to comply them. I think I'm asking your opinions because I still suffer from many bugs despite all my effort on many of these practices. Bug fix may be, or should be, faster than before, but I couldn't really measure the improvement. Moreover, much of my time has been invested on defence, meaning that I haven't actually done much data analysis (offence) these days. Where is the point I should stop at in terms of productivity? I've already deployed: 1a,b,c, 2a, 3a,b,c, 4b,c, 5a,d, 6a,b, 7a,7b I'm about to have a go at: 5b,c Not yet: 2b,c, 4a, 7c, 8a,b,c (I could not really see the advantage of using GNU make (2c) for my purpose. Could anyone tell me how it helps my work with MATLAB?)

• The Winds of Change are a Blowin&rsquo;

  - by Ajarn Mark Caldwell

  For six years I have been an avid and outspoken fan and paying customer of SourceGear products…from Vault to Dragnet to Fortress and on to Vault Professional, but that is all changing now.  Not the fan part, but the paying customer part.  I’m still a huge fan.  I think that SourceGear does a great job with their product and support has been fantastic when needed (which is not very often).  I think that Eric Sink has done a fine job building a quality company and products, and I appreciate his contributions to the tech community through this blogging and books.  I still think their products are high quality and do a fantastic job of what they do.  But there’s the rub…what they do is no longer enough for me. As I have rebuilt our development team over the last couple of years, and we have begun to investigate Scrum and Kanban, I realize that I need more visibility into the progress of the team.  I need better project management tools, and this is where Vault Professional lags behind several other tools.  Granted, in the latest release (Vault 6.0) they added a nice time tracking feature, but I want more.  (Note, I did contact SourceGear about my quest for more, but apparently, the rest of their customer base has not been clamoring for this and so they have not built it.  Granted, I wasn’t clamoring for it either until just recently, but unfortunately for SourceGear, I want it now and don’t want to wait for them to build it into their system.) Ironically, it was SourceGear themselves who started to turn me on to the possibilities of other tools.  They built a limited integration with Axosoft OnTime which I read about several times on their support site (I used to regularly read and occasionally comment on their Support Forum).  I decided to check out OnTime and was very impressed with the tool for work item tracking and project management (not to mention their great Scrum Master in 10 Minutes video).  I fell in love with the capabilities of OnTime.  Unfortunately, the integration with Vault for source control management was, as I mentioned, limited.  I could have forfeited the integration between work items and source code, but there is too much benefit to linking check-ins to work items for me to give that up.  So then I did what was previously unthinkable for me, I considered switching not just the work tracking tool, but also the source code management tool.  This was really stepping outside my comfort zone because source code is Gold, and not to be trifled with.  When you find a good weapon to protect your gold, stick with it. I looked at Git and Tortoise SVN, but the integration methods for those was pretty rough compared to what I was used to.  The recommended tool from Axosoft’s point of view appeared to be RocketSVN, but I really wasn’t sure I wanted to go the “flavor of Subversion” route.  Then I started thinking about that other tool I liked back when I first chose to go with Vault, but couldn’t afford:  Team Foundation Server.  And what do you know…Microsoft has not only radically improved it over that version from back in 2006, but they also came to their senses about how it should be licensed, and it is much more affordable now.  So I started looking into the latest capabilities in the 2012 version, and I fell in love all over again. I really went deep on checking out the tools.  I watched numerous webcasts from Microsoft partners, went to a beta preview on Microsoft’s campus, and watched a lot of Channel 9 videos on the new ALM features (oooh…shiny).  Frankly, I was very impressed with the capabilities of the newest version, and figured this was probably our direction.  As an interesting twist of fate, one of my employees crossed paths with an ALM Consultant from Northwest Cadence, a local Microsoft Partner, and one of the companies that produced several of the webcasts that I had been watching.  So I gave Bryon a call and started grilling him to see if he really knew anything or was just another guy who couldn’t find a job so he called himself a consultant.  It turns out Bryon actually knows a lot, especially in an area that was becoming a frustration point for us: Branching strategies and automated builds (that’s probably a whole separate blog entry).  As we talked, Bryon suggested we look into doing a DTDPS (Developer Tools Deployment Planning Services) session with his company.  This is a service that can be paid for by Microsoft Enterprise Agreement planning services credits or SA training benefits, and, again, coincidentally, we had several that were just about to expire, so I put them to good use. The DTDPS sessions were great; and Bryon, Rick, and the rest of the folks at Northwest Cadence have been a pleasure to work with.  We have just purchased a new server for our TFS rollout and are planning the steps and options right now.  This is still a big project ahead of us to not only install and configure TFS, but also to load all of our source code (many different systems, not just one program) and transition to the new way of life with TFS, but I am convinced that it is the right move for my team at this point in time.  We need the new capabilities that are in alignment with Scrum and Kanban methodologies in order to more efficiently manage all the different projects that we have going on at one time. I would still wholeheartedly endorse SourceGear’s products and Axosoft’s OnTime for those whose needs are met by those tools, but for me and my team, I think that TFS is the right fit, and I am looking forward to the change.

• Using SQL Source Control with Fortress or Vault &ndash; Part 2

  - by AjarnMark

  In Part 1, I started talking about using Red-Gate’s newest version of SQL Source Control and how I really like it as a viable method to source control your database development.  It looks like this is going to turn into a little series where I will explain how we have done things in the past, and how life is different with SQL Source Control.  I will also explain some of my philosophy and methodology around deployment with these tools.  But for now, let’s talk about some of the good and the bad of the tool itself. More Kudos and Features I mentioned previously how impressed I was with the responsiveness of Red-Gate’s team.  I have been having an ongoing email conversation with Gyorgy Pocsi, and as I have run into problems or requested things behave a little differently, it has not been more than a day or two before a new Build is ready for me to download and test.  Quite impressive! I’m sure much of the requests I put in were already in the plans, so I can’t really take credit for them, but throughout this conversation, Red-Gate has implemented several features that were not in the first Early Access version.  Those include: Honoring the Fortress configuration option to require Work Item (Bug) IDs on check-ins. Adding the check-in comment text as a comment to the Work Item. Adding the list of checked-in files, along with the Fortress links for automatic History and DIFF view Updating the status of a Work Item on check-in (e.g. setting the item to Complete or, in our case “Dev-Complete”) Support for the Fortress 2.0 API, and not just the Vault Pro 5.1 API.  (See later notes regarding support for Fortress 2.0). These were all features that I felt we really needed to have in-place before I could honestly consider converting my team to using SQL Source Control on a regular basis.  Now that I have those, my only excuse is not wanting to switch boats on the team mid-stream.  So when we wrap up our current release in a few weeks, we will make the jump.  In the meantime, I will continue to bang on it to make sure it is stable.  It passed one test for stability when I did a test load of one of our larger database schemas into Fortress with SQL Source Control.  That database has about 150 tables, 200 User-Defined Functions and nearly 900 Stored Procedures.  The initial load to source control went smoothly and took just a brief amount of time. Warnings Remember that this IS still in pre-release stage and while I have not had any problems after that first hiccup I wrote about last time, you still need to treat it with a healthy respect.  As I understand it, the RTM is targeted for February.  There are a couple more features that I hope make it into the final release version, but if not, they’ll probably be coming soon thereafter.  Those are: A Browse feature to let me lookup the Work Item ID instead of having to remember it or look back in my Item details.  This is just a matter of convenience. I normally have my Work Item list open anyway, so I can easily look it up, but hey, why not make it even easier. A multi-line comment area.  The current space for writing check-in comments is a single-line text box.  I would like to have a multi-line space as I sometimes write lengthy commentary.  But I recognize that it is a struggle to get most developers to put in more than the word “fixed” as their comment, so this meets the need of the majority as-is, and it’s not a show-stopper for us. Merge.  SQL Source Control currently does not have a Merge feature.  If two or more people make changes to the same database object, you will get a warning of the conflict and have to choose which one wins (and then manually edit to include the others’ changes).  I think it unlikely you will run into actual conflicts in Stored Procedures and Functions, but you might with Views or Tables.  This will be nice to have, but I’m not losing any sleep over it.  And I have multiple tools at my disposal to do merges manually, so really not a show-stopper for us. Automation has its limits.  As cool as this automation is, it has its limits and there are some changes that you will be better off scripting yourself.  For example, if you are refactoring table definitions, and want to change a column name, you can write that as a quick sp_rename command and preserve the data within that column.  But because this tool is looking just at a before and after picture, it cannot tell that you just renamed a column.  To the tool, it looks like you dropped one column and added another.  This is not a knock against Red-Gate.  All automated scripting tools have this issue, unless the are actively monitoring your every step to know exactly what you are doing.  This means that when you go to Deploy your changes, SQL Compare will script the change as a column drop and add, or will attempt to rebuild the entire table.  Unfortunately, neither of these approaches will preserve the existing data in that column the way an sp_rename will, and so you are better off scripting that change yourself.  Thankfully, SQL Compare will produce warnings about the potential loss of data before it does the actual synchronization and give you a chance to intercept the script and do it yourself. Also, please note that the current official word is that SQL Source Control supports Vault Professional 5.1 and later.  Vault Professional is the new name for what was previously known as Fortress.  (You can read about the name change on SourceGear’s site.)  The last version of Fortress was 2.x, and the API for Fortress 2.x is different from the API for Vault Pro.  At my company, we are currently running Fortress 2.0, with plans to upgrade to Vault Pro early next year.  Gyorgy was able to come up with a work-around for me to be able to use SQL Source Control with Fortress 2.0, even though it is not officially supported.  If you are using Fortress 2.0 and want to use SQL Source Control, be aware that this is not officially supported, but it is working for us, and you can probably get the work-around instructions from Red-Gate if you’re really, really nice to them. Upcoming Topics Some of the other topics I will likely cover in this series over the next few weeks are: How we used to do source control back in the old days (a few weeks ago) before SQL Source Control was available to Vault users What happens when you restore a database that is linked to source control Handling multiple development branches of source code Concurrent Development practices and handling Conflicts Deployment Tips and Best Practices A recap after using the tool for a while

• How can a code editor effectively hint at code nesting level - without using indentation?

  - by pgfearo

  I've written an XML text editor that provides 2 view options for the same XML text, one indented (virtually), the other left-justified. The motivation for the left-justified view is to help users 'see' the whitespace characters they're using for indentation of plain-text or XPath code without interference from indentation that is an automated side-effect of the XML context. I want to provide visual clues (in the non-editable part of the editor) for the left-justified mode that will help the user, but without getting too elaborate. I tried just using connecting lines, but that seemed too busy. The best I've come up with so far is shown in a mocked up screenshot of the editor below, but I'm seeking better/simpler alternatives (that don't require too much code). [Edit] Taking the heatmap idea (from: @jimp) I get this and 3 alternatives - labelled a, b and c: The following section describes the accepted answer as a proposal, bringing together ideas from a number of other answers and comments. As this question is now community wiki, please feel free to update this. NestView The name for this idea which provides a visual method to improve the readability of nested code without using indentation. Contour Lines The name for the differently shaded lines within the NestView The image above shows the NestView used to help visualise an XML snippet. Though XML is used for this illustration, any other code syntax that uses nesting could have been used for this illustration. An Overview: The contour lines are shaded (as in a heatmap) to convey nesting level The contour lines are angled to show when a nesting level is being either opened or closed. A contour line links the start of a nesting level to the corresponding end. The combined width of contour lines give a visual impression of nesting level, in addition to the heatmap. The width of the NestView may be manually resizable, but should not change as the code changes. Contour lines can either be compressed or truncated to keep acheive this. Blank lines are sometimes used code to break up text into more digestable chunks. Such lines could trigger special behaviour in the NestView. For example the heatmap could be reset or a background color contour line used, or both. One or more contour lines associated with the currently selected code can be highlighted. The contour line associated with the selected code level would be emphasized the most, but other contour lines could also 'light up' in addition to help highlight the containing nested group Different behaviors (such as code folding or code selection) can be associated with clicking/double-clicking on a Contour Line. Different parts of a contour line (leading, middle or trailing edge) may have different dynamic behaviors associated. Tooltips can be shown on a mouse hover event over a contour line The NestView is updated continously as the code is edited. Where nesting is not well-balanced assumptions can be made where the nesting level should end, but the associated temporary contour lines must be highlighted in some way as a warning. Drag and drop behaviors of Contour Lines can be supported. Behaviour may vary according to the part of the contour line being dragged. Features commonly found in the left margin such as line numbering and colour highlighting for errors and change state could overlay the NestView. Additional Functionality The proposal addresses a range of additional issues - many are outside the scope of the original question, but a useful side-effect. Visually linking the start and end of a nested region The contour lines connect the start and end of each nested level Highlighting the context of the currently selected line As code is selected, the associated nest-level in the NestView can be highlighted Differentiating between code regions at the same nesting level In the case of XML different hues could be used for different namespaces. Programming languages (such as c#) support named regions that could be used in a similar way. Dividing areas within a nesting area into different visual blocks Extra lines are often inserted into code to aid readability. Such empty lines could be used to reset the saturation level of the NestView's contour lines. Multi-Column Code View Code without indentation makes the use of a multi-column view more effective because word-wrap or horizontal scrolling is less likely to be required. In this view, once code has reach the bottom of one column, it flows into the next one: Usage beyond merely providing a visual aid As proposed in the overview, the NestView could provide a range of editing and selection features which would be broadly in line with what is expected from a TreeView control. The key difference is that a typical TreeView node has 2 parts: an expander and the node icon. A NestView contour line can have as many as 3 parts: an opener (sloping), a connector (vertical) and a close (sloping). On Indentation The NestView presented alongside non-indented code complements, but is unlikely to replace, the conventional indented code view. It's likely that any solutions adopting a NestView, will provide a method to switch seamlessly between indented and non-indented code views without affecting any of the code text itself - including whitespace characters. One technique for the indented view would be 'Virtual Formatting' - where a dynamic left-margin is used in lieu of tab or space characters. The same nesting-level data used to dynamically render the NestView could also used for the more conventional-looking indented view. Printing Indentation will be important for the readability of printed code. Here, the absence of tab/space characters and a dynamic left-margin means that the text can wrap at the right-margin and still maintain the integrity of the indented view. Line numbers can be used as visual markers that indicate where code is word-wrapped and also the exact position of indentation: Screen Real-Estate: Flat Vs Indented Addressing the question of whether the NestView uses up valuable screen real-estate: Contour lines work well with a width the same as the code editor's character width. A NestView width of 12 character widths can therefore accommodate 12 levels of nesting before contour lines are truncated/compressed. If an indented view uses 3 character-widths for each nesting level then space is saved until nesting reaches 4 levels of nesting, after this nesting level the flat view has a space-saving advantage that increases with each nesting level. Note: A minimum indentation of 4 character widths is often recommended for code, however XML often manages with less. Also, Virtual Formatting permits less indentation to be used because there's no risk of alignment issues A comparison of the 2 views is shown below: Based on the above, its probably fair to conclude that view style choice will be based on factors other than screen real-estate. The one exception is where screen space is at a premium, for example on a Netbook/Tablet or when multiple code windows are open. In these cases, the resizable NestView would seem to be a clear winner. Use Cases Examples of real-world examples where NestView may be a useful option: Where screen real-estate is at a premium a. On devices such as tablets, notepads and smartphones b. When showing code on websites c. When multiple code windows need to be visible on the desktop simultaneously Where consistent whitespace indentation of text within code is a priority For reviewing deeply nested code. For example where sub-languages (e.g. Linq in C# or XPath in XSLT) might cause high levels of nesting. Accessibility Resizing and color options must be provided to aid those with visual impairments, and also to suit environmental conditions and personal preferences: Compatability of edited code with other systems A solution incorporating a NestView option should ideally be capable of stripping leading tab and space characters (identified as only having a formatting role) from imported code. Then, once stripped, the code could be rendered neatly in both the left-justified and indented views without change. For many users relying on systems such as merging and diff tools that are not whitespace-aware this will be a major concern (if not a complete show-stopper). Other Works: Visualisation of Overlapping Markup Published research by Wendell Piez, dated from 2004, addresses the issue of the visualisation of overlapping markup, specifically LMNL. This includes SVG graphics with significant similarities to the NestView proposal, as such, they are acknowledged here. The visual differences are clear in the images (below), the key functional distinction is that NestView is intended only for well-nested XML or code, whereas Wendell Piez's graphics are designed to represent overlapped nesting. The graphics above were reproduced - with kind permission - from http://www.piez.org Sources: Towards Hermenutic Markup Half-steps toward LMNL

• iptables DNS resolution

  - by Favolas

  I have a virtual machine with Fedora 19 acting as a router. This machine as an interface (p8p1) with the IP 172.16.1.254 that is connected to another machine (IP 172.16.1.1) that's simulating the external network. I've installed snort 2.9.2.2, applied the snortsam-2.9.2.2.diff.gz patch and installed snortsam 2.70 on the routermachine In snort.conf besides altering some RULE_PATH I believe I've only added the following line to the file. output alert_fwsam: 127.0.0.1:898/password After doing this two comands: ifconfig p8p1 promisc /usr/local/snort/bin/snort -v -i p8p1 If I ping from the external network to the router IP, I can see the info about the pings. One of the rules that I have is icmp-info.rules that as this single line: alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"ICMP-INFO Echo Reply"; icode:0; itype:0; classtype:misc-activity; sid:408; rev:6;fwsam: src, 5 minutes;) snortsam.conf as this data: defaultkey password accept localhost keyinterval 30 minutes dontblock 192.168.1.1 # rede local rollbackhosts 50 rollbackthreshold 20 / 30 secs rollbacksleeptime 1 minute logfile /var/log/snort/snortsam.log loglevel 3 daemon nothreads # linha importante para gerar os bloqueios via iptables iptables p8p1 LOG bindip 127.0.0.1 Now I run this command: /usr/local/snort/bin/snort -u snort -i p8p1 -c /etc/snort/snort.conf -l /var/log/snort -Dq Terminal gives this message: Spawning daemon child... My daemon child 2080 lives... Daemon parent exiting (0) and when I runsnortsam in terminal i got this: SnortSam, v 2.70. Copyright (c) 2001-2009 Frank Knobbe . All rights reserved.

Linking plugin 'iptables'... Checking for existing state file "/var/db/snortsam.state". Found. Reading state file. Starting to listen for Snort alerts. and snortsam.log as an entry like this 2013/10/25, 10:15:17, -, 1, snortsam, Starting to listen for Snort alerts. Now, from the external machine I do ping 172.16.1.254 and it starts showing the info and an alert file is created in /var/log/snort/ that as the info about the PINGS. Something like: [**] [1:408:6] ICMP-INFO Echo Reply [**] [Classification: Misc activity] [Priority: 3] 10/25-10:35:16.061319 172.16.1.254 -> 172.16.1.1 ICMP TTL:64 TOS:0x0 ID:38720 IpLen:20 DgmLen:84 Type:0 Code:0 ID:1389 Seq:1 ECHO REPLY Also, if I run instead /usr/local/snort/bin/snort snort -v -i p8p1 i got this message: Running in packet dump mode --== Initializing Snort ==-- Initializing Output Plugins! Snort BPF option: snort pcap DAQ configured to passive. The DAQ version does not support reload. Acquiring network traffic from "p8p1". ERROR: Can't set DAQ BPF filter to 'snort' (pcap_daq_set_filter: pcap_compile: syntax error)! Fatal Error, Quitting.. So, this are my questions: Shouldn't snortsam block the PING? Is that DAQ error causing the problem? If so, How can I solve it?
