• How to disable visual effects and compiz 100%

  - by oshirowanen

  UPDATE 1: The problem is not a monitor refresh rate flickering problem, as then the whole screen would be flickering. For me, only the application windows flicker in and out of view, then most of the time, when there do decide to show themselves, they only partly show themselves, like just top half, bottom half, left half, corner missing, window disappears when you try moving it or mouse over it even etc etc. I know it is a visual effect problem as I know my computer cannot handle visual effects and for some reason when the windows do appear partly, I can see the shadows behind the windows. Those shadows are part of the visual effects which are turned on by default for some reason. I get the same problem with 10.04, but can quickly turn off the visual effects by right clicking the desktop, selecting change background image, and in the visual effects tab, I can click on none, which stops all the visual problems. ORIGINAL QUESTION: I am having problems with 11.04 on my computer. For some reason it is enabling visual effects by default in the live cd when it should not be as my computer cannot support such effects. My computer cannot support Unity either, but it defaults to standard gnome with visual effects for some reason. It should be defaulting to standard gnome with no visual effects. THerefore, all I get is a very flickery live cd which makes it very difficult to see anything. So my question is, how do I disable the visual effects from the live cd? To put it simply, the live cd flickering is so bad, that I had to log back into my standard 10.04 install just to write this question, as I just couldn't see enough of the screen because of the flickering in 11.04 to even get to askubuntu.com...

• Automated Acceptance tests under specific contraints

  - by HH_

  This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

• Command line: Map network drive

  - by Seb Nilsson

  How do I write a command line in a .bat or .cmd that maps a network drive? I want the script to first check if the drive-letter is mapped, and if it is delete it and then map the drive. I only have the mapping-command right now. Please help me fill in the blanks: REM Check if drive exists, if it does, delete it @echo off net use q: /persistent:yes \\localhost\C$\MyFolder pause Are there any of the parameters wrong? Any that should be added?

• local user cannot access vsftpd server

  - by Zloy Smiertniy

  I'm currently running a vsftpd server and I added the necessary configurations in vsftpd.conf so that local users can use clients like FileZilla to manage their homes in a server. I found out that only users in the sudoers list access without a problem only they can't download the files, but users that are not sudoers cannot even access their homes from a client but they can access by a web browser using the FTP protocol and they can only access their home directories (as intented) Im running a fedora 14 on my server and my vsftpd.conf looks like this: # Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid.

• Cloud services, Public IPs and SIP

  - by Guido N

  I'm trying to run a custom SIP software (which uses JAIN SIP 1.2) on a cloud box. What I'd really like is to have a real public IP aka which is listed by "ifconfig -a" command. This is because atm I don't want to write additional SIP code / add a SIP proxy in order to manage private IP addresses / address translation. I gave Amazon EC2 a go, but as reported here http://stackoverflow.com/questions/10013549/sip-and-ec2-elastic-ips it's not fit for purpose (they do a 1:1 NAT translation between the private IP of the box and its Elastic IP). Does anyone know of a cloud service that provides real static public IP addresses?

• Which web site gives the most accurate indication of a programmer's capabilities?

  - by Jerry Coffin

  If you were hiring programmers, and could choose between one of (say) the top 100 coders on topcoder.com, or one of the top 100 on stackoverflow.com, which would you choose? At least to me, it would appear that topcoder.com gives a more objective evaluation of pure ability to solve problems and write code. At the same time, despite obvious technical capabilities, this person may lack any hint of social skills -- he may be purely a "lone coder", with little or no ability to help/work with others, may lack mentoring ability to help transfer his technical skills to others, etc. On the other hand, stackoverflow.com would at least appear to give a much better indication of peers' opinion of the coder in question, and the degree to which his presence and useful and helpful to others on the "team". At the same time, the scoring system is such that somebody who just throws up a lot of mediocre (or even poor answers) will almost inevitably accumulate a positive total of "reputation" points -- a single up-vote (perhaps just out of courtesy) will counteract the effects of no fewer than 5 down-votes, and others are discouraged (to some degree) from down-voting because they have to sacrifice their own reputation points to do so. At the same time, somebody who makes little or no technical contribution seems unlikely to accumulate a reputation that lands them (even close to) the top of the heap, so to speak. So, which provides a more useful indication of the degree to which this particular coder is likely to be useful to your organization? If you could choose between them, which set of coders would you rather have working on your team?

• Incompatible group permissions in Linux - Is it a bug?

  - by Sachin

  I am on Ubuntu 11.04. I am creating another user and placing an existing user in the group of other user, hoping to write in the home directory of other user. # uname -a Linux vini 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:18:14 UTC 2011 i686 athlon i386 GNU/Linux # whoami sachin # su root # useradd -m -U foo // create user foo # usermod -a -G foo sachin // add user `sachin' to group `foo' # chmod 770 /home/foo/ # exit # whoami sachin # cd /home/foo/ bash: cd: /home/foo/: Permission denied # groups sachin sachin : sachin foo This is totally weird. Though user sachin is in group foo, and group bits for /home/foo/ is set to rwx, sachin can't chdir to /home/foo/. I am not able to understand this. But, if at the exit step, I switch to sachin user from root, this is what happens: # uname -a Linux vini 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:18:14 UTC 2011 i686 athlon i386 GNU/Linux # whoami sachin # su root # useradd -m -U foo // create user foo # usermod -a -G foo sachin // add user `sachin' to group `foo' # chmod 770 /home/foo/ # su sachin # whoami sachin # cd /home/foo/ # ls examples.desktop Now, whatever is happening here is totally incomprehensible. Does su sachin inherits some permissions from the root user at this step? Any explanations would be much appreciated.

• Creating a FAT file system and save it into a file in GNU/linux?

  - by RubenT

  I tell you my problem: I want to create a FAT file system and save it into a so I can mount it in linux using something like: sudo mount -t msdos <file> <dest_folder> Maybe I'm wrong and this cannot be done. Anyway, the problem is this: I'm trying to create the file containing a FAT file system, and I'm running this command: sudo mkfs.vfat -F 32 -r 112 -S 512 -v -C "test.fat" 100 That, accordingly to the mkfs man page, will create a FAT32 file system with 112 rootdir entries, logical sector size of 512 bytes, 100 blocks in total, and save it into "test.fat". But it fails, and the bash tells me: mkfs.vfat: unable to create test.fat What is going on? I think I am misunderstanding how mkfs works and how to use it. It is possible to write a filesystem into a file?

• Building a Redundant / Distributed Application

  - by MattW

  This is more of a "point me in the right direction" question. My team of three and I have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

• Justifying a memory upgrade, take 2

  - by AngryHacker

  Previously I asked a question on what metrics I should measure (e.g. before and after) to justify a memory upgrade. Perfmon was suggested. I'd like to know which specific perfmon counters I should be measuring. So far I got: PhysicalDisk/Avg. Disk Queue Length (for each drive) PhysicalDisk/Avg. Disk Write Queue Length (for each drive) PhysicalDisk/Avg. Disk Read Queue Length (for each drive) Processor/Processor Time% SQLServer:BufferManager/Buffer cache hit ratio What other ones should I use?

• Is there a secure way to add a database troubleshooting page to an application?

  - by Josh Yeager

  My team makes a product (business management software) that our customers install on their own servers. The product uses a SQL database for data storage and app configuration. There have been quite a few cases where something strange happened in the customer's database (caused by bugs in our app and also sometimes admins who mess with the database). To figure out what is wrong with the data, we have to send SQL scripts to the customer and tell them how to run them on the database server. Then, once we know how to fix it, we have to send another script to repair the data. Is there a secure way to add a page in our application that allows an application admin to enter SQL scripts that read and write directly to the database? Our support team could use that to help customers run these scripts, without needing direct access to the SQL server. My big concerns are that someone might abuse this power to get data they shouldn't have and maybe to erase or modify data that they shouldn't be able to modify. I'm not worried about system admins, because they could find another way to do the same thing. But what if someone else got access to the form? Is there any way to do this kind of thing securely?

• Microsoft Access as a Weapon of War

  - by Damon

  A while ago (probably a decade ago, actually) I saw a report on a tracking system maintained by a U.S. Army artillery control unit.  This system was capable of maintaining a bearing on various units in the field to help avoid friendly fire.  I consider the U.S. Army to be the most technologically advanced fighting force on Earth, but to my terror I saw something on the title bar of an application displayed on a laptop behind one of the soldiers they were interviewing: Tracking.mdb Oh yes.  Microsoft Office Suite had made it onto the battlefield.  My hope is that it was just running as a front-end for a more proficient database (no offense Access people), or that the soldier was tracking something else like KP duty or fantasy football scores.  But I could also see the corporate equivalent of a pointy-haired boss walking into a cube and asking someone who had piddled with Access to build a database for HR forms.  Except this pointy-haired boss would have been a general, the cube would have been a tank, and the HR forms would have been targets that, if something went amiss, would have been hit by a 500lb artillery round. Hope that solider could write a good query :)

• what are some good interview questions for a position that consists of reviewing code for security vulnerabilities?

  - by John Smith

  The position is an entry-level position that consists of reading C++ code and identifying lines of code that are vulnerable to buffer overflows, out-of-bounds reads, uncontrolled format strings, and a bunch of other CWE's. We don't expect the average candidate to be knowledgeable in the area of software security nor do we expect him or her to be an expert computer programmer; we just expect them to be able to read the code and correctly identify vulnerabilities. I guess I could ask them the typical interview questions: reverse a string, print a list of prime numbers, etc, but I'm not sure that their ability to write code under pressure (or lack thereof) tells me anything about their ability to read code. Should I instead focus on testing their knowledge of C++? Ask them if they understand what a pointer is and how bitwise operators work? My only concern about asking that kind of question is that I might unfairly weed out people who don't happen to have the knowledge but have the ability to acquire it. After all, it's not like they will be writing a single line of code, and it's not like we are looking only for people who already know C++, since we are willing to train the right candidate. (It is true that I could ask those questions only to those candidates who claim to know C++, but I'd like to give the same "test" to everyone.) Should I just focus on trying to get an idea of their level of intelligence? In other words, should I get them to talk and pay attention to the way they articulate their thoughts, and so on?

• Rails time stamps on images in CSS

  - by brad

  Just posted this on Stack but realized it may be more appropriate here: So Rails time stamping is great. I'm using it to add expires headers to all files that end in the 10 digit timestamp. Most of my images however are referenced in my CSS. Has anyone come across any method that allows for timestamps to be added to CSS referenced images, or some funky re-write rule that achieves this? I'd love for ALL images in my site, both inline and in css to have this timestamp so I can tell the browser to cache them, but refresh any time the file itself changes. I couldn't find anything on the net regarding this and I can't believe this isn't a more frequently discussed topic. I don't think my setup will matter because the actual expiring will hopefully happen the same way, based on the 10 digit timestamp, but I'm using apache to serve all static content if that matters

• How do I convince my boss that it's OK to use an application to access an outside website?

  - by Cyberherbalist

  That is, if you agree that it's OK. We have a need to maintain an accurate internal record of bank routing numbers, and my boss wants me to set up a process where once a week someone goes to the Federal Reserve's website, clicks on the link to get the list of routing numbers (or the link giving the updates since a particular date), and then manually uploads the resultant text file to an application that will make the update to our data. I told him that a manual process was not at all necessary, and that I could write a routine that would access the FED's routing numbers in the application that keeps our data updated, and put it on whatever schedule was appropriate. But he is greatly opposed to doing this, and calls it "hacking the Federal Reserve website." I think he's afraid that the FED is going to get after us. I showed him the FED's robot.txt file, and the only thing it forbids is an automated indexing of pages with extension .cf*: User-agent: * # applies to all robots Disallow: CF # disallow indexing of all CF* directories and pages This says nothing about accessing the same data automatically that you could access manually. Anyone have a good counterargument to the idea that we'd be "hacking" the FED?

• Too much free space on FreeNAS - ZFS

  - by Guillaume

  I have a FreeNAS server with 3 x 2 To disks in raidz1. I would expect to have about 4 To of space available. When I run zpool list I get: [root@freenas] ~# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT main_volume 5.44T 3.95T 1.49T 72% ONLINE /mnt I was expecting a size of 4 To. Also, used space as reported by zpool list does not match what's reported by du: [root@freenas] ~# du -sh /mnt/main_volume/ 2.6T /mnt/main_volume/ There are quite a few things that I dont yet completely understand about ZFS. But at the moment I am mostly worried that I misconfigured my system and that I dont have any storage redundancy. How can I make sure I did not do an horrible mistake ...

• How can i get my KVM switch to work? (win7 & ubuntu 10.10)

  - by Will W.

  i bought a KVM switch and i'm trying to use it to have it connected to my main PC (win7) and my new machine i just installed ubuntu on. I hooked it up properly, and tried using it. It worked when switching from the win7 machine to the ubuntu one, but after the (1st and only) successful switch, ubuntu just didn't seem to recognize my mouse or keyboard. Basically when i tried it the easiest was to explain what happened was it only worked with Win7. When i switched over to ubuntu by doing a [scroll-lock] [scroll-lock], my keyboard and mouse were not recognized. However, the lights on the keyboard and mouse did work when on ubuntu, but they didn't function, and since keyboard wouldn't function, i couldn't do a [scroll-lock] [scroll-lock] to switch back to the win7 machine. So i was basically locked in to ubuntu with no mouse or keyboard, and i had to unplug the keyboard/mouse usb's and d-sub to plug the monitor d-sub back into win7 computer to type up this thread and google the issue. Seems some people have had this issue before but i couldn't find a fix... I am 80% sure it has to do with drivers... but there isn't any for KVM switches, at least not this one also i never was unable to find ubuntu drivers/firmware for my mouse and keyboard (Logitech G15 and Razer Deathadder 3500). I don't know how to fix this, perhaps someone super-savvy could write/code a script or work-around or something? I really need to get this thing working, my back is getting sore from bending over and plugging in / unplugging usb/monitor/usb/monitor/usb/usb over and over again lol... and i really would be sad if the constant plugging unplugging of the usb's or the d-sub port would over time damage the ports... i don't want that... There has to be some way to get this working.. Can anyone help? The KVM is a IOGEAR GCS632U Win7 x64 Ubuntu 10.10

• Connecting to wireless networks from command line

  - by Balaji

  I need to write a shell script which connects to one of the two available wi-fi connections. One is a un secure connection and the other is secure connection. My question has 2 parts- 1.How to connect to the un-secure (un-encrypted and no password required) connection from command line (or by executing a shell script) when I'm connected to the secure connection? I followed the steps in http://www.ubuntugeek.com/how-to-troubleshoot-wireless-network-connection-in-ubuntu.html for in-secure connection. I put all the commands in a script and executed it (I made sure that interface name and essid are correct) - sudo dhclient -r wlan0 - sudo ifconfig wlan0 up - sudo iwconfig wlan0 essid "UAPublic" - sudo iwconfig wlan0 mode Managed - sudo dhclient wlan0 But nothing happens - I'm not disconnected from the current network and connected to the new one 2.When I want to connect to the secure wi-fi network, I understand from http://askubuntu.com/a/138476/70665 that I need to use wpa_supplicant. But I enter a lot of details in the interface when I connect via UI security : wpa and wpa2 enterprise Authentication : PEAP CA certificate : Equifax... PEAP version : automatic inner authentication : MSCHAPv2 username : password : How to use wpa_supplicant to mention all these details in the command line? The conf file network={ ssid="ssid_name" psk="password" } doesn't work for me.

• Wordnik Accelerator

  - by prabhpreet

  Wow, creating IE Accelerators is superbly easy. If you want to learn how to create one, go here (some MSDN blog) and the MSDN documentation (clearly written). I was fed up of dictionary.com bringing all those popups and the stupid definitions of Google's dictionary. So I decided to scratch my own itch. I randomly stumbled on the site called Wordnik and it provides with all examples plus definitions plus lots more for words and its popup-free (as far as I know). So I decided to write and accelerator. Here is the source code (Yes, this is it): <?xml version="1.0" encoding="utf-8"?> <os:openServiceDescription xmlns:os="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://www.wordnik.com</os:homepageUrl> <os:display> <os:name>View on Wordnik</os:name> <os:description>Looking up words on an awesome word site called Wordnik </os:description> <os:icon>http://www.wordnik.com/favicon.ico</os:icon> </os:display> <os:activity category="Define"> <os:activityAction context="selection"> <os:execute method="get" action="http://www.wordnik.com/words/{selection}" ></os:execute> </os:activityAction> </os:activity> </os:openServiceDescription> That’s it. To get it, go here. Enjoy!

• Anonymouse VS Logged in users on my site & Google Analytics

  - by Flowpoke

  I'd like to be able to run two different 'tracks' for Google Analytics; One for anonymous users of the site and another for Users whom are logged-in. I say "track" because Im not sure of the term--but I definitely know I want it to all be in the same "Analytics Account", I just want to segregate my logged-in users... In the site template, I can very easily add a conditional to display one or the other (Analytics code snippet)... Which Im hoping this comes down to and although Im not sure, it seems that the last digit in your Analytics ID (e.g. UA-15XXXX0-X) could be incremented to gain such additional 'tracks'....? Any tips? Am I doin it wrong? My current footer snippet: <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA-XXXXXXX-1"); pageTracker._trackPageview(); } catch(err) {} </script>
