• Terminal, vim and ssh color problem

  - by xaph

  I'm using vim for my editor. I've problems about the colors of vim. The same colorscheme of vim gives different outputs in terminal, ssh session and screen. I learnt they've different colors(16, 88 or 256). I don't care of using 16 color or 256 color. Also the terminal emulator is not very important to me. My questions: 1- How do I use same vim colorscheme with same output on everywhere? 2- I want to write a color definition and use it every terminal(maybe with Xdefaults file). Is it possible?

• "Tail" a logstash server query

  - by phatmanace

  Assuming I have a logstash server chocked full of logs being loaded regularly, is there a reasonably elegant way that I can tail the results of a continuously executing query on the logstash server and show this in a terminal window e.g some-special-logstash-command.sh | egrep -v "(searchword1|searchword2)" the idea being that the command pipes stuff out of logstash and to my grep query that filters and shows me the filtered output for. .. of course if there is a logstash command that can do the grep piece for me as well, then that works too :) motivation for doing this, is that assuming all of my events from my estate is being loaded into logstash, then would be nice to have a terminal window with a continuous tail of interesting events as they occur scrolling past the screen. -Ace

• Good practice on Visual Studio Solutions

  - by JonWillis

  Hopefully a relativity simple question. I'm starting work on a new internal project to create tractability of repaired devices within the buildings. The database is stored remotely on a webserver, and will be accessed via web API (JSON output) and protected with OAuth. The front end GUI is being done in WPF, and the business code in C#. From this, I see the different layers Presentation/Application/Datastore. There will be code for managing all the authenticated calls to the API, class to represent entities (business objects), classes to construct the entities (business objects), parts for WPF GUI, parts of the WPF viewmodels, and so on. Is it best to create this in a single project, or split them into individual projects? In my heart I say it should be multiple projects. I have done it both ways previously, and found testing to be easier with a single project solution, however with multiple projects then recursive dependencies can crop up. Especially when classes have interfaces to make it easier to test, I've found things can become awkward.

• Compilation problem [closed]

  - by Misery

  I am trying to compile a program called Triangle Mesh Generator. It is an open source code written in ANSI C. I need it to bo a callable lib so I am using a switch (#define) created by it's Author. However I get this error: /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/crt1.o: In function `_start': collect2: ld returned 1 exit status make: *** [triangle] Error 1 I am not sure why such an error occurs. Worth adding is that compiling it as a stand alone program is succesful. I am using GCC on 12.04. The lines quoted above constitute the total output. What I put in the terminal is just make in the proper folder. There are no other errors, warnings, or other messages. Link to the sources I found some additional instructions. I'll get back after reading them :] EDIT: I have found some additional instructions that let me compile it. Thanks for help. I am closing question right now. Regards

• Clean logging with BASH

  - by Matt Krouse

  I have a script that deletes files 7 days or older and then logs them to a folder. It logs and deletes everything correctly but when I open up the log file for viewing, its very sloppy. log=$HOME/Deleted/$(date) find $HOME/OldLogFiles/ -type f -mtime +7 -delete -print > "$log" The log file is difficult to read Example File Output: (when opened in notepad) /home/u0146121/OldLogFiles/file1.txt/home/u0146121/OldLogFiles/file2.txt/home/u0146121/OldLogFiles/file3.txt Is there anyway to log the file nicer and cleaner? Maybe with the Filename, date deleted, and how old it was? Any suggestions help!

• SQL Server: How to report error from a job's step of PowerShell type

  - by Ariel

  I have a SQL job whose step of 'PowerShell' type does 'exit 1' if encounters an error i.e. $ErrorActionPreference='stop'; trap{"$_"; exit 1} Problem is, SQL Server doesn't pay attention to that exit code, and reports "The step did not generate any output. Process Exit Code 0. The step succeeded." Any idea how to successfully tell SQL Server from a PowerShell step that something went wrong? Thanks in advance.

• insert, delete etc. keys not working on Cherry Strait keyboard

  - by Brabster

  Hey folks, I got a Cherry Strait USB wired keyboard for xmas and I've been unable to get several keys working under Ubuntu 10.10 or Win XP. There are a few keys. including the Print Screen key, insert, end, delete, pg up, pg down and home. I've not been able to identify any others that aren't working. I'm not sure as to the best approach to determine what's wrong. Is there any way to confirm whether there is any output from the keyboard in response to pressing those keys, ideally in Ubuntu as that's where I spend most of my time so that I know if it's a fault with the device itself? (I've tried different USB ports and also hitting those keys whilst in the Keyboard Shortcuts app, no response to these keys)

• check two conditions in two different columns in excel and count the matches

  - by user1727103

  I've trying to create a Error Log to help me analyse my mistakes. So for simplicity, lets assume I have two columns "Type of Question" - with values SC,RC,CR and another column that indicates whether I got this question "right/wrong".Let's assume this is my table: Question No. | Right/Wrong | Question Type | Right | SC | Right | RC | Wrong | SC | Wrong | CR | Right | RC (Pardon my formatting skills). And I want an output table like this Type of Question | Right | Wrong | Total SC | 1 | 1 | 2 RC | 2 | 0 | 2 CR | 0 | 1 | 1 So basically what I want to do is check Column3 for SC using =COUNTIF(C1:C5,"SC"), and return the total number of SC questions, and then outta the SC , I need to find out which are Right.If I know the right and the total I can get the wrong. I have never written a macro so a formula based answer would suffice.

• Recursively copy only new or changed files

  - by Niklas

  I'm sure this must have been asked and answered before, but I just can't find it right now... I have a Visual Studio post-build action that currently does a recursive copy (using xcopy) of an output folder to a different folder. This takes longer than I like and I'd like to only copy newly created and newer (changed) files each time (which xcopy doesn't seem to support). I cannot depend on any not-installed-by-default tool since the solution is used by different developers on different machines. What would a superuser do?

• syslog log of TCP packet

  - by com

  Occasionally, I noticed a lot of following messsages in syslog Nov {datetime} hostname kernel: [8226528.586232] AIF:PRIV TCP packet: IN=eth0 OUT= MAC={mac} SRC={sourceip} DST={destinationip} LEN=60 TOS=0x00 PREC=0x00 TTL=63 ID=20361 DF PROTO=TCP SPT=39950 DPT=37 WINDOW=14600 RES=0x00 SYN URGP=0 On the Internet, I found that DOS attack may cause such type of output, unfortunately, I don't understand what does this log mean. The only thing is clear for me is this log is related to network. The source host is the host where nagios is installed. Does it mean nagios somehow does behave well? And what does it mean at all?

• Changing languages rapidly causes Linux to crash.

  - by eZanmoto

  So I'm running Xmonad on my college computer (which runs Kubuntu) and whenever I leave my desk, instead of using x-screensaver which is incredibly buggy and slow, I just change to another workstation, open a terminal and change language to a language which uses symbols instead of letters, and then change back using an aliased command. For example, my .profile has the lines alias qwer="setxkbmap jp" alias *******="setxkbmap ie" where ******* is my password, using japanese characters. Changing languages seems to be much faster than running x-screensaver. The problem: rapidly changing languages seems to crash Linux; it just won't accept input (and it's not because the language hasn't changed back, nothing is output to the console). I can't use Ctrl+Alt+F1..F7, I can't "raise the elephants", anything, it just won't work. I'm just wondering, is this a known issue, and if so, is there something I can do about it?

• Google Music Player doesn't work

  I'm trying to log in on Google Music Player application but doesn't work. I get the message below: Login Failed Could not identify your computer.

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. The laptop has a Intel 4500 video card. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• Apache configuration file visualization/testing

  - by Matt Holgate

  Is there a tool available (or a debug mode built into Apache) that will allow me to interactively test and explain an Apache configuration for a given request? In particular, I'd like to be able to see which directives will apply when requesting a specific URL. For example, the output for the URL http://myserver.com/foo/bar/bar.html might look something like: Allow from 192.168.0.3 <-- From <Location /foo/bar> in myserver.com vhost Require valid user <-- From <Directory /var/www/foo> in global configuration Satisfy any <-- From <File bar.html> in global configuration [Background: why do I want this? The apache merging rules for configuration directives are quite complex to get right. It would be great to have a tool which allows you to check that your rules are doing exactly what you want, and would be a good learning tool]. If there isn't such a tool, is there a debug option in Apache that will log such information for each incoming request?

• Windows partition UNKNOWN after Ubuntu installation attempt at dual boot - How to fix?

  - by user285645

  The idea was to install Win 7 and Ubuntu with dual boot. However, after installation, Gparted shows a /dev/sda1 as an 'unknown' filesystem and its size is 278 GB. All my windows files, data are in this partition. THen, there's /dev/sda2 with 'EXT4' filesystem (size-9.54 GB) - created during Ubuntu install. Then, there's /dev/sda3 with 'extended' filesystem (size- 10.5 GB) - created during Ubuntu install. Then, there's /dev/sda5 with 'linux swap' filesystem (size- 2 GB) - created during Ubuntu install. Then, there's /dev/sda6 with 'ext4' filesystem (size- 8.5 GB) - created during Ubuntu install. MY questions are: What exactly does this Gparted output above mean? How to recover my previous Windows 7 installation that's in /dev/sda1 (NTFS). I have some important files I need. Also, I had a PGP encryption on the disk before installing Ubuntu. Now, it just boots straight into Ubuntu... why? How to uninstall Ubuntu (the Try ubuntu and uninstall did not work. the boot-repair did not work) I have read other topics but noone has provided a proper step by step answer to how to recover my 278GB WIndows partition. The testdisk step by step procedure did not work. It says the NTFS disk is unrecognized.

• A Dozen USB Chargers Analyzed; Or: Beware the Knockoffs

  - by Jason Fitzpatrick

  When it comes to buying a USB charger one is just as good as another so you might as well buy the cheapest one, right? This interesting and detailed analysis of name brand, off-brand, and counterfeit chargers will have you rethinking that stance. Ken Shirriff gathered up a dozen USB chargers including official Apple chargers, counterfeit Apple chargers, as well as offerings from Monoprice, Belkin, Motorola, and other companies. After putting them all through a battery of tests he gave them overall rankings based on nine different categories including power stability, power quality, and efficiency. The take away from his research? Quality varied widely between brands but when sticking with big companies like Apple or HP the chargers were all safe. The counterfeit chargers (like the $2 Apple iPad charger knock-off he tested) proved to be outright dangerous–several actually melted or caught fire in the course of the project. Hit up the link below for his detailed analysis including power output readings for the dozen chargers.

• 3 Monitors on a Notebook

  - by Rihan Meij

  I would like to use 3 screens on my Dell Inspiron 1720 So On the laptop built in screen have that as one, and then have 2 more screens. The catch is, that I want to play racing games with this set-up. So that my main screen is the focus area (the front window if you will) and the other 2 screens will be used for peripheral vision, on the side. The software that I use (LFS.net) does support multiple screens. However the notebook can have the main screen on, and another external screen. So I would need to split this "second" monitor output, to 2 screens, the one to the left of the main monitor, and the other one to the right. Is this possible? Is there perhaps a external card / docking station solution that could help with this? Any advice or ideas is greatly appreciated. Best Regards Rihan

• rewrite map (prg:) never finishes

  using Apache and a prg type rewrite map.
