• tunneling x11vnc through ssh on a non standard port to ubuntu computer tightvnc

  - by user72372

  I have been stuck with setting up my virtual desktop on my ubuntu laptop. I am running ubuntu to ubuntu with x11vnc I start the process on my laptop as follows: " ssh -L5904:localhost:5900 -p Port remoteuser@remoteip." That command works, then I start x11vnc server, "x11vnc -noncache -once -shared -rfbauth ~/.vnc/passwd." This command works and starts connection. Then I open another window on my laptop and type, export VNC_VIA_CMD='/usr/bin/ssh -2 -c aes128-cbc -x -p Port -l User -f -: %L:%H:%R %G sleep 20' (not sure if works). then I type, vncviewer -endcodings Tight -depth 8 -quality 1 -via IPofremotemachine -u remoteuser localhost:01. The first time it work but from now on it just gives me the vncviewer -help screen everytime. I type in the password for my remote machine and then shows -help screen for vncviewer. I think the problem is with Tightvnc viewer but don't know what. Please help. I got some info on www.vanemery.com/Linux/VNC/vnc-over-ssh.html?.

• Compiling custom kernel 3.7.x lowlatency on Ubuntu 12.04

  - by FlabbergastedPickle

  All, I have a peculiar problem with trying to compile a lowlatency flavor of the latest 3.7 kernel. I retrieved the prepatched source from the launchpad using bzr, compiled it using the usual make-kpkg using the current config file plus default options for the rest, installed the kernel and booted into it. Everything works except for the fglrx and wl drivers that I had to install in the original 12.04 lowlatency kernel. So, I tried recompiling these and succeeded with both of them (no errors were reported)--wl driver required a minor adjustment to system.h include while latest fglrx 12.11 beta11 (released yesterday, Dec. 3rd, 2012) compiled without the hitch. Yet, when I try to modprobe either module (both having in common the fact that they were built after the kernel, fglrx as a deb, and wl via the usual make/make install), I get "FATAL: no MODULENAME module found" (MODULENAME being either wl or fglrx). The graphic driver watermark shows 3D crossed out and "for testing purposes" (or "unsupported hardware," can't remember), and no fglrx or wl is loaded. More mysteriously, dmesg shows no attempt on kernel's behalf to load the said drivers, even though they are clearly in the right /lib/modules/KERNEL_VERSION folder. How is this possible? Has something fundamentally changed in 3.7 kernel that would prevent modprobing of these? I know that there is driver signing option that was merged recently but as far as I could tell the kernel config file generated by the build process had that disabled. OTOH, while building wl driver, I did get a warning that the driver was not signed... Then again, even if the kernel disallowed loading of those modules, shouldn't dmesg reflect that? Any thoughts on this one are most appreciated.

• I can't delete a file - even when using unlocker

  - by chipperyman573

  So I have a 64 bit windows 7 ultimate computer. On my desktop, I have a .iso file that should NOT be used by anything. However, when I use lockhunter (unlocker doesn't work for me), it says it can't unlock or delete it. When I check what it's being used by, it says by the system. Here's a picture when I click delete: Here's a picture of when I click unlock it: When I click Other Close locking process: I've had this file on my computer for a LONG time now and haven't been able to delete it. I've also tried eraser erase on startup, but that doesn't work, either. How can I remove this file?

• setting up freedns with an existing domain

  - by romeovs

  I've been running a webserver off of a pc at a static IP succesfully for the past 5 months. recently however, I've moved into another appartment and my ISP only provides a dynamic IP (my IP changes from time to time). I'm not an internet genius but I was thinking to fix this by using a Dynamic DNS provider. So I got on the web and found freedns. I'm a bit confused about how to set up everything though. I've managed to succesfully install the IP updater daemon on my web server. Then, in my registrars control panel, I set the NS records to point at ns1 through ns4.afraid.org (removing the old NS records). I'm not certain what I should do with the A records though (for now they are still pointing to the old static IP address). I have A records for www, blog, irc, etc. but I cannot point them at my new IP address, because it isn't Could someone explain this in the clearest possible sense (perhaps elaborating on what happens at each step of the DNS process). I never really knew what the A records are for anyway. (note that I haven't really found any documentation at the freedns website, or on google)

• wrong kernel running after install

  - by ticktockhouse

  I have installed Ubuntu 14.04 from unetbootin. When it reboots after the install, uname -r says: 3.5.0-17-generic ..this means that no modules have loaded for the kernel that is actually installed (3.13.0-32-generic). Does anyone know why this kernel should be installed via the install process? Is it an artifact of using Unetbootin? Booting into the Unetbootin image gives the correct kernel, and thus the modules load. Knowing why is one thing, but I'm not sure how to remedy it now. Because no modules are loaded, I can't connect to the network or connect a USB drive. I've tried update-grub, which seems to find the correct kernel, but doesn't seem to tell the system to boot from it. I've also tried selecting the kernel at boot time using the "Advanced Options for Ubuntu", and the 3.13.x kernel is the only one listed. Selecting this lead to the 3.5.x kernel stubbornly loading.. I'm a fairly accomplished sysadmin, but this one has me flummoxed :) Can anyone help?

• Android From Local DB (DAO) to Server sync (JSON) - Design issue

  - by Taiko

  I sync data between my local DB and a Server. I'm looking for the cleanest way to modelise all of this. I have a com.something.db package That contains a Data Helper and couple of DAO classes that represents objects stored in the db (I didn't write that part) com.something.db --public DataHelper --public Employee @DatabaseField e.g. "name" will be an actual column name in the DB -name @DatabaseField -salary etc... (all in all 50 fields) I have a com.something.sync package That contains all the implementation detail on how to send data to the server. It boils down to a ConnectionManager that is fed by different classes that implements a 'Request' interface com.something.sync --public interface ConnectionManager --package ConnectionManagerImpl --public interface Request --package LoginRequest --package GetEmployeesRequest My issue is, at some point in the sync process, I have to JSONise and de-JSONise my data (E.g. the Employee class). But I really don't feel like having the same Employee class be responsible for both his JSONisation and his actual representation inside the local database. It really doesn't feel right, because I carefully decoupled the rest, I am only stuck on this JSON thing. What should I do ? Should I write 3 Employee classes ? EmployeeDB @DatabaseField e.g. "name" will be an actual column name in the DB -name @DatabaseField -salary -etc... 50 fields EmployeeInterface -getName -getSalary -etc... 50 fields EmployeeJSON -JSON_KEY_NAME = "name" The JSON key happens to be the same as the table name, but it isn't requirement -name -JSON_KEY_SALARY = "salary" -salary -etc... 50 fields It feels like a lot of duplicates. Is there a common pattern I can use there ?

• Defining formula through user interface in user form

  - by BriskLabs Pakistan

  I am a student and developing a simple assignment - windows form application in visual studio 2010. The application is suppose to construct formulas as per user requirement. The process: It has to pick data from columns of Microsoft Access database and the user should be able to pick the data by column name like we do in a drop down menu. and create reusable formulas in it ( configure it once and can change it again). followings are column titles from database that can be picked for example. e.g Col -1 : Marks in Maths Col -2 : Total Marks in Maths Col -3 : Marks in science Col -4 : Total marks in science Finally we should be able to construct any formula in the UI like (Col 1 + Col 3 ) / ( col 2 + col 4) = Formula 1 once this is formula is set saved and a name is assigned to it by user. he/she can use the formula and results shall appear in a window below. i.e He would be able to calculate his desired figures (formula) by only manipulating underlying data on the UI layer....choose the data for a period and apply the formula and get the answer Problem: It looks like I have to create an app where rules are set through UI....... this means no stored procedures are required in SQL.... please suggest the right approach.

• Object construction design

  - by James

  I recently started to use c# to interface with a database, and there was one part of the process that appeared odd to me. When creating a SqlCommand, the method I was lead to took the form: SqlCommand myCommand = new SqlCommand("Command String", myConnection); Coming from a Java background, I was expecting something more similar to SqlCommand myCommand = myConnection.createCommand("Command String"); I am asking, in terms of design, what is the difference between the two? The phrase "single responsibility" has been used to suggest that a connection should not be responsible for creating SqlCommands, but I would also say that, in my mind, the difference between the two is partly a mental one of the difference between a connection executing a command and a command acting on a connection, the latter of which seems less like what I have been lead to believe OOP should be. There is also a part of me wondering if the two should be completely separate, and should only come together in some sort of connection.execute(command) method. Can anyone help clear up these differences? Are any of these methods "more correct" than the others from an OO point of view? (P.S. the fact that c# is used is completely irrelevant. It just highlighted to me that different approaches were used)

• Setting up podcasting for a non-tech user

  - by Force Flow

  I have a user who wants to start making podcasts, but they only have basic skills when it comes to technology. So, I was trying to get a process together that would be easy for them to follow. To upload files (the mp3's and rss feed files), I have an explorer shortcut for their FTP space. To record the podcast, I was going to either use audacity or PodProducer. For the RSS feed, I was looking for a podcast RSS generator of some sort. In my search for this, I've come across a lot of dead links and a lot of paid tools, so I haven't come up with anything too useful. Is there a free, reliable webservice or windows-based tool available that folks like to use?

• Upgrading from php 5.3 to php 5.4 with Macport

  - by dr.stonyhills

  PHP5.4 has been available for sometime now and Macport recently caught up with the release of port php54 but the process of upgrading is not as clear as possible. Even worst for those who are new to maintaining multiple versions of PHP on the same machine. I am keen on trying out some of the new features in PHP5.4 like traits, new array form etc but falling back on to php5.3 for other compatibility stuff. So i sudo port install php5+ (all the variants, apache2 etc) Then i tell it what PHP port to use as default sudo port select --set php php54 Check what version of PHP is active in the terminal using php -v outputs php 5.4.3. But i seem to be having issues with choosing the right non cli version as in the version of the module run by apache etc is still php5.3.12. Do i have to change the reference to the libphp5 in apache httpd.conf? Any advice on the right workflow for switching between php version on macport greatly appreciated!

• The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

  - by Hunter2

  Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

• How do I make a Windows virtual machine replicate to another datacenter/cloud?

  - by zippy

  We have a Windows 2008 VM running IIS and SQL Server Express (it's an all-in-one web application). We need to have another copy at our secondary datacenter site. What is the best way to do this? It doesn't have to be running all the time but it has to have almost the latest copy of the current VM. I took a look at VMWare Fault Tolerance and after the heart attack at the price I starting looking for another solution. If need be I wouldn't mind copying it over to a cloud VM provider, if I can find one that lets me copy my own VMs up and start them up without any conversion process.

• Bugzilla random lag and CPU usage

  - by Serty Oan

  Here is the configuration : Bugzilla (3.4.2) application running on a Ubuntu server 8.04 with Perl 5.8.8. Here is the problem : Sometimes (randomly), pages take very long to load. It can be any of the login page or query.cgi page or buglist.cgi... etc... Using top on the server, I tried to see what was wrong, and saw that sometimes a bugzilla script would use 30% memory and last pretty long (1 to 5 seconds) and sometimes not even show in the list because it responded too quickly or just use 2%. The mysqld process does not seems to be the problem.

• Filter MP3s by encoder type?

  - by Brandon

  I'm on a Mac and use iTunes to manage my music collection. I'm in the process of weeding out the lower quality files that I have and would like to have only MP3s that have been encoded using the V0 setting of the LAME MP3 encoder. I tried using iTunes' smart playlist feature but as it only allows a less than rule and V0 is a variable amount, it catches valid V0 encoded files a lot of the time. Is there any alternative program on Mac that I can just point to my iTunes folder and say, "show me all files that are not encoded with LAME V0"?

• Daily Weekly and Monthly DB backup with logrotate?

  - by benjisail

  I am currently keeping daily backup of my database by doing a daily mysqldump and by using logrotate to keep the 7 last days of mysqldump. I would like to improve this backup process to keep 7 daily backup, 3 weekly backups and 12 monthly backup. I found this article which explain how to di this with logrotate : http://www.hotcoding.com/os/sysadmin/35751.html However I am using the dateext logrotate option to name my backup files so I cannot use this solution. How can I do daily, weekly and monthly backup with logrotate and with the dateext option?

• How to upgrade to Windows 8.1 on a machine with a Users folder on a separate drive?

  - by ahsteele

  I tried to upgrade from Windows 8 to Windows 8.1. Unfortunately, during the upgrade process I receive the following error: Sorry, it looks like this PC can't run Windows 8.1. This might be because the Users or Program Files folder is being redirected to another partition. Which is accurate in that I have my Users directory on my D: drive and Windows installed on my C: drive. I do this because my C: drive is an SSD drive and D: drive is a spinning rust drive where I keep my data. Is it possible to upgrade to Windows 8.1 from a Windows 8 install with a redirected Users folder? I do not consider a full reinstall of Windows 8 with a non-mapped Users folder and then upgrading that installation to be "upgrading."

• Windows 8 Store App Crash Logs

  - by David Paquette

  I was recently working on a Windows 8 app, and the application was crashing occasionally.  When resuming the application, the app would crash and close immediately without providing any feedback or information on what went wrong.  The crash was very difficult to reproduce, and I could never get the crash to occur when I was debugging through Visual Studio.  My app was crashing, and I had no idea what was going wrong!  HELP!!! After doing some digging, I found that when a Windows 8 Store App crashes, an error is logged in Windows Administrative Events.  You can view the details of any app crash by launching the Event Viewer and selecting Administrative Events under Custom Views.  The Source of the error will be listed as AppHost.  AppHost is the process that runs your Windows 8 Store App.  The error details contain all the information you would expect to find, including a stack trace and line numbers.   Windows 8 Tip:  A shortcut for launching the Event Viewer in Windows 8.  Right click on the bottom left corner of your desktop (where you normally click to go to the Start Screen).  A menu will appear with shortcuts to a number of common system tasks such as Event Viewer, Task Manager, Command Prompt, and Device Manager.

• Postgresql starup script for second instance?

Or is there some better way to make second init script for postgresql? P.S. (I'm using Ubuntu)

  I'm trying to stop a RAID disk in order to replace it by a new one, as this one is not working properly. I'm typing mdadm --stop /dev/md1, and I'm getting an error message: mdadm: fail to stop array /dev/md1: Device or resource busy I'm getting this message even if I reboot the server, and I can't see a process that could cause this.

• Automatic switching between "digital output" (HDMI) and built-in speakers in Vista

  - by Laurence Gonsalves

  We occasionally connect my wife's laptop, which runs Vista, to our TV. Whenever we do this we have to manually switch the default audio output to "digital output" for the sound to go through the HDMI connection, and we also have to restart any apps that we want to send sound to the TV. We then have to perform a similar process when disconnecting. Is there any way to just have this be automatic? It seems absurd to have to do so much manual fiddling when a 40 year old transistor radio is "smart" enough to turn off the speakers and send sound to the headphones when headphones are plugged in. In case it helps, the name "RealTek" shows up in the sound card settings dialog.

• cygwin rsync over ssh very slow

  - by Waleed Hamra

  I have 2 machines running Windows Xp SP3. I have cygwin installed on both, version 1.7. I have rsync and ssh installed on both, and configured using default settings as per ssh-host-config and ssh-user-config programs provided. I moved the public keys into their respective locations, and basically ssh is working fine. i began an rsync operation, using: rsync -av --delete --hard-links local_dir username@other_machine:/some_dir well... on both machines, the processor is running near idle, no heavy usage. I checked IO using process explorer on both machines, and that too is at normal levels (1~2 MB/s), so I can't see where the bottlenecks are, because network performance is aweful. I'm not going over 1MB/s... when a normal file copy using windows sharing achieves some ~10 MB/s.. What could be wrong?

• For those of you who are senior developers what do you look for in a new company and development team?

  - by Amy P

  As I move forward in my career new jobs become more difficult to choose between. When I was starting out and for the first 8 years of my career I took the jobs that I could get that would keep me programming on the general technological path that I was on. I am a job hopper, I only stay with a company for between 2 - 3 years. I think that I do this because after 2 years I get bored and unless there are new projects to keep my busy I no longer find work interesting. Now that I am becoming more experienced it is more important for me to only apply for jobs that are interesting and will move my career and my skill set forward. My problem now is that I keep finding jobs where the projects appear to be interesting during the interview but once I get in the company I find the development environment is sub-par and the development team is disjointed. I feel like I am asking the wrong questions during the interview process and don't know what to look for to make sure that the environment I will be working in will be a good one. Now my question: For those of you who are senior developers what do you look for in a new company and development team? I am looking for the key qualities in a company and development team that you look for when interviewing with a company. These qualities are the ones that would give you hints that the company will be a good one to work for.
