• Are there videocamera which geotag individual frames?

  - by Grzegorz Adam Hankiewicz

  I'm looking for a way to record live video with the specific requirement of having each frame georeferenced with GPS. Right now I'm using a normal video camera with a PDA+GPS that records the position, but it's difficult to sync both of these plus sometimes I've forgotten to turn the PDA+GPS or it has failed for some reason and all my video has been useless. Using google I found that about two years ago a company named Seero produced such video cameras and software, but apparently the domain doesn't exist any more and I only find references of other pages mentioning it. Does somebody know of any other product? I need to record this video in HD and have some way to export to Google Maps or other GIS software the positions of the frames in a way that I can click on the map and see what was being recorded in the video at that point. The precission of the GPS tracking is good enough as one position per second, intermediate frames of the video stream can be interpolated.

• Can somebody help me install this jBPM based workflow management suite?

  - by Eternal Saint

  1.Its a book Workflow Interface software available at sourceforge http://bookworkflowint.sourceforge.net/ Any instructions on installing and configuring it would be great especially in windows, however I can try Linux specific ones as well. I could not find any installation instructions. I posted this in stackoverflow by mistake and was directed here. 2.Can you guys suggest any good scanning/digitization workflow software (document imaging) that I can adopt to my scanner software? Infact even a simple one would do may be based on hotfolders. I just want to be able to track the uniqueid/barcode of the scanned book, its status so that its not scanned again. It books or manuscripts could be in millions page count. I thought of using some kind of generic bug tracking tool, just track a few fields, dont know if its the right choice Thank you very much

• How to calculate time spent for Linux system administration?

  - by Jaakko

  I would love figuring out how much time I actually have spent in shell performing administrative duties. For billing of course, this information is not sufficient, but it would be helpful to figure out how much time I have actually spent in shell. My question is: How anyone got tips on how to calculate time spent in shell (in hours + minutes), let's say per user account? Could anyone recommend a software that could be used to analyze this time? Optionally I would like to know about ways how to categorise time spent (e.g. 1 hour for Apache, 2 hours for Samba, etc.) Also, your takes on how you monitor your admin time, are also much appreciated! To narrow down the problem, I am specifically interested in ways of tracking time spent in shell for Linux system administration

• 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.

• Webserver security, intrusion detection, and file intregrity

  - by enfield

  I would like to add some type of tracking / alerting on some linux webservers running PHP and Apache. In doing searches I have come across a lot of info from 2006-2009. Would like to revisit things and see what others are doing now. The main purpose here is to track when any files are changed and if so alert me somehow. The same goes for IDS and hopefully something that can reside on same server? Since some of these are small scale projects I would prefer opensource/free solutions that are really effective. Although I would still like to hear of other alternatives if someone has the experience and the cost can be justified.

• How to redirect (or Alias) jump page with Apache

  - by Meltemi

  I'm not an Apache expert but need to make a small change to a web server. We are introducing a "jump page" URL that is different from a primary URL (for tracking reasons). /productA/index.html /productA/jump_index.html Basically i want to log that jump_index.html was requested and then return index.html. I don't want the client to wait 8 seconds or so for a redirect. How should we be handling this? Simply symlink (or alias) the file in the filesystem? Use mod_alias Alias Match (if so how exactly)? something better still? Edit: mod_rewrite in httpd.conf: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_METHOD} ^TRACE RewriteRule .* - [F] </IfModule>

• PostgresQL on Amazon EBS volume, realistic performance, or move to something more lightweight?

  - by Peck

  Hi, I'm working on a little research project, currently running as an instance on ec2, and I'm hoping to figure out whether I'm going down the right path. We, like a thousand other people, are making use of some of twitters streaming feeds to do gather some data to have fun with and my db seems to be having problems keeping up, and queries take what seems to be a very long time. I'm not a DBA by trade, so I'll just dump some info here and add more if need be. System specs: ec2 xl, 15 gigs of ram ebs: 4 100 gb drives, raid 0. The stream we're getting we're looking at around 10k inserts per minute. 3 main tables, with the users we're tracking somewhere in the neighborhood of 26M rows currently. Is this amount of inserts on this hardware too much to ask out of ebs? Should take a look at some things with less overhead like mongodb?

• File access with hostname or ip only - no domain?

  - by Jonathon

  It seems likely that this is an obvious question, but I'm having trouble tracking down any useful information. Normally when accessing files in a particular directory on a server, I'm able to create a virtual host, assign a domain, root directory location, etc -- however am in a situation where I have server space and need to access files with only a hostname. Is this possible? For example, let's say the hostname is 123hostname.com, and the file I want access to is in /home/sub-directory/filename.php. How do I get at it via a browser? I've tried: http://123hostname.com/home/sub-directory/filename.php ...and some other variations on that theme (that I can't post because new users are restricted to one link in messages). But generally stuck. Any help -- even if it's just to let me know that this isn't possible without some additional configuration -- would be great. Thank you!

• How to set the request start time with HAProxy?

  - by Tupy

  I would like to measure the time of full request stack. The New Relic capture time of the middleware (e.g. java, python, ruby) and request time (See https://newrelic.com/docs/features/tracking-front-end-time). For this, I need to configure the X-Request-Start header as the request pass through the HAProxy load balance. The haproxy.cfg should look like: backend www balance roundrobin mode http reqadd "X-Request-Start" UNKNOWN_TIME_FUNCTION() server servername 192.168.0.1:80 weight 1 check There is a haproxy native function to replace the UNKNOWN_TIME_FUNCTION()?

• Sendmail relay out of Amazon EC2?

  - by Stephen Belanger

  I have a site running on CentOS 5.4 through Amazon EC2. Unfortunately, Amazon has had nothing but trouble with their entire IP range getting black listed from spam tracking services regularly. I need a mail server, so I setup an smtp server elsewhere that I want to send to, but I can't just send directly to it through PHP because the direct smtp request is way too slow. What I want to do is relay through sendmail, but I've never used sendmail before, so I have no idea how to configure it. All I want is for all emails sent from localhost to be relayed to one specific external server, but I don't know how to do that. I tried to find a tutorial online, but couldn't find anything that was particularly clear as to how I go about doing that. Can anyone help me out?

• How to set up Mac Os X like dragging behaviour on Linux

  - by ticking

  I would like to use Linux(Fedora) on a Aluminum MacBook Pro, but since the Touchpad on a MacBook Pro is only a giant button Apple does some custom tracking. When there is one finger placed, and a second follows (the click can occur before or after that) it will be interpreted as a drag. So the strong thumb can be used to hold pressure and the more accurate index finger can do the pointing. But Linux interprets this as a right click, since it only cares if two fingers are on the pad. Is there a way to achieve said behaviour? Cheers Jan

• How to identify cause of system lock on debian squeeze?

  - by David Sanders

  I have a desktop system at work with debian squeeze installed. Every couple days or so, when I come in in the morning, the system appears to be asleep and won't wake up. I suspect it goes into power save mode and then doesn't receive the wake up signal when I click the mouse or touch the keyboard. Does anyone know where I should look in order to start tracking this down? Like log files, etc? I doubt it, but maybe the fact that I'm using a mac aluminum usb keyboard and a wireless usb mouse (that has an off switch) has something to do with it? Maybe, when I turn my mouse off at the end of the day, the system loses track of the device somehow? I dunno :P. Thanks in advance.

• Steps to make sure network is not blacklisted...Again

  - by msindle

  I have an interesting issue. I have a client that just got blacklisted due to spam being sent out over the last 2 days. I have my firewall configured to only allow mail to go outbound on port 25 from our mail server (Exchange 2010) exclusively and I have verified that there are no open relay's on our transport rules. We are running Vipre Business and after running deep scans with updated definitions all computers come back clean. I ran a message tracking report on our Exchange server that shows all mail sent via the mail server over the last couple of weeks and didn't see anything malicious or out of the ordinary. I have also verified that there are no home devices or rouge computers on the network. For all practical purposes it appears that the network is clean, but we still wound up on 5 or 6 blacklists...Where should I start looking next? Is there a "best practices" guide that can help eradicate this issue? Thanks in advance! msindle

• Any worker agent monitors for appliance based load balancers?

  - by Zethris

  Looking to find out to what extent an appliance load balancer can monitor servers for both failover (say for example a service like apache tomcat fails) and load balancing? Right now it looks like it's just port monitoring/connection tracking and healthcheck urls that it will heartbeat and detect as down if it doesn't come back with a finished request. We are looking at the Kemp 3500 or Loadbalancer.org solutions. Is there any sort of web application level monitoring/load balancing that these load balancers can offer that can more directly interact with the servers it's balancing?

• rsync - How to exclude one .htaccess but not all of them

  - by Cory Gagliardi

  I have an rsync command for copying my files from dev to production. I don't want to copy the .htaccess file that's in the root of the HTML directory but, I do want to copy the few .htaccess files that are in its sub directories. I'm using the argument --exclude .htaccess which is stopping all of the files from getting copied. The other arguments I'm including are -a --recursive --times --perms. Is it possible to configure rsync to do this? Edit: Here is my full command: rsync -a --recursive --times --perms \ --exclude prop_images --exclude tracking --exclude vtours \ --exclude .htaccess --exclude .htaccess_backup --exclude "*~" \ /home/user/dev_html/* /home/user/public_html/

• IE 8 doesn't appear to clear cache on demand. Is anyone else seeing this?

  - by Steve

  I have a client that uploads updated pdf files to her Concrete5 CMS, through the file manager, replacing the old file with the same name. She then does a cms "clear cache" and exits as she should. Then, in testing, she finds that the old file still comes up when clicking on the link. On further review, the cms file manager version tracking shows that the file has been updated, and, for me, the new file comes up, as it should, when clicking the link. My client hase also refreshed her browser cache and still, she only gets the old file when clicking on the link. She says that, while she can't seem to force an immediate cache update, overnight it appears to update. My client is also part of a large company-wide lan and intranet. Is it possible that there is a cache function placed outside of her local browser and cms cache that is not updating?

• How do I get detailed information about what happens during logon

  - by Funky Si

  Due to my IT department leaving I am now responsible for all our IT systems. I now have several problems to get my head around and fix. I run Active Directory on windows server 2003 and use group policy to apply settings etc. Recently we have had some windows 7 clients added to our network, these are having awful problems with our logon scripts and drive mappings. For the most part my XP clients are working without a problem. What I want to know is what is going on during logon, as running the logon scripts after I have logged on often works. Does anyone know of a way to get detailed log information of what is happening before and during logon. Thanks for your help and any suggestions you have for tracking down the source of these problems.

• System Restore Points

  - by Ross Lordon

  Currently I am investigating how to schedule an automatic initiation of a system restore point for all of the workstations in my office. It seems that Task Scheduler already has some nice defaults (screenshots below). Even the history for this task verifies that it is running successfully. However, when I go to Recovery in the Control Panel it only lists the System Restore Points one for every previous for only 3 weeks back even if I check the show more restore points box. Why don't the additional ones appear? Would there be a better way to implement a solution, like via group policy or a script? Is there any documentation on this online? I've been having a hard time tracking anything down except how to subvert group policy disabling this feature.

• Redundant Router and Load Balancing vs. DDoS attack

  - by colgatta

  With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?

• My laptop was stolen. What do I need to do?

  - by chris

  My laptop was recently stolen. It was a corporate system running XP, which means it was part of a domain - I'm assuming that makes it impossible for someone to log into it, although I know there are ways to reset the local admin account. Is there any way to tell if someone boots it up? I was logged into gmail, using two factor authentication. I will change my password, but is there any chance of tracking any attempted accesses? Other than changing passwords on all my web accounts, is there anything else I need to do?

• nginx: rewrite URL but have original URL stored in access.log as 200

  - by mhambra

  I'm setting up a link tracking system, which (temporarily) involves adding /link/id/ in front of URL (like http://server/data/id/publication/id/). rewrite data/id/(.*) http://server/$1; The request is logged as: ip - - [17/Nov/2011:10:07:19 +0300] "GET /data/id/publication/id.html HTTP/1.1" 302 154 "-" "UA"` For some reason (keeping the compatibility with AWStats) it is wanted to have 200 logged instead of 302. (nginx allows to get 301 code out of box with permanent option, but thats inappropriate too) What are my options here? Will the combination of location { } and rewrite do the job?

• Good free software to track and graph memory and CPU usage on Windows?

  - by TheLQ

  There are many questions on Linux memory tracking, but I haven't seen any for Windows. In my case however its a Windows XP Pro box I need to track the memory and CPU usage of. The reason I need it is due to a server program I'm trying that is eating all my processor and some of my memory which is freezing my RDP session and System Explorer and even makes it difficult to login physically. As this is a very constrained server I'm working off of (768 MB RAM with Pentium 4 which disappears with this program), I need a program that doesn't run/require a webserver. I can give it a MySQL database if necessary however. Is there any suggestions for such a program?

• Looking for temporal upsampling / motion interpolation software

  - by timday

  I'm looking for something (prereably FOSS software) which can take an animation with N images as input, and which will output an animation with M frames, where M is in the range 2N to 5N or so. I believe the general technique is called "temporal upsampling" or possibly "inbetweening" (or "'tweening" for short). Note that it does need to make some effort to do motion tracking of things in the scene ("optical flow"); just fading ("dissolve") between keyframes isn't going to cut it. Googling "temporal upsampling" turns up any number of papers on the subject, but I've yet to discover any code/software (a gstreamer plugin would be perfect) I can just use to try the technique out. Any suggestions ? Additional information: "Motion interpolation" seems to be the more widely used name in the TV world for what I'm looking for. See this and the video here too. Interestingly, some cinephiles seem to hate what these technologies do to 24FPS film: e.g a comment "makes Gone With The Wind look like a soap opera shot on video".
