• Stupid question: prevent file from being changed under linux

  - by Josh

  Ok. Stupid question. I have forgotten what this is called and without remembering the name the search function on the site and on google is failing me. What's the command under linux to mark a file as "locked"/to prevent any changes from being made to it? I'm not talking about chmod. There's a property that can be set (again the name escapes me at the moment) which prevents even processes running as root from changing a file. What is this called and how do I set it?

• why Apache with ssl but back end weblogic without ssl works?

  - by huangli

      Hello everyone. my question is very simple . The link below is a picture about my architecture. https://docs.google.com/open?id=0BxSXbpgYIZVOR212RVk4ZDN1Sm8.      The pic above shows the architecture right now and it works correctly ! which means I could visit apache with url https//apchehost:8080, could not visit the web app with https served by weblogic but I could visit these app with https served by Apache(Apache is proxy server).      My question is why the Apache is configured with ssl but weblogic without ssl works ? I think weblogic should also configured with ssl . If this works , what about security level ? Is the ssl really works if only Apache configured with ssl but Weblogic without it ? Thanks . condition: Apache 2.2.17 with weblogic module mod_wl_22.so Weblogic: 10.3 OS: Windows server 2003

• Select firefox search result

  - by Nicolas C.

  I am working on a daily basis on a web application with very large menus. Also doing lots of other Excel manipulations, copy and pasting, etc., I am quite fond of keyboard shortcuts as much faster than using the mouse to point, double-click and then going back to my keyboard etc. Hence, my question is quite simple, does anyone know if there is any shortcut under Firefox which would let me actually select (and not highlight) in my web page the search result so that I can for instance do the following manipulation sequence? [Ctrl]+[F] type the search string, for instance 'regional_unit' the missing shortcut to actually select in my page the string which is currently highlighted thanks to the search feature of FF [Space] or [Enter] key to activate the web element which in my case would systematically correspond to a link or button, etc. May be there would be an addon replacing the default search feature, I don't know... I tried to look over the internet but with the words I am using for this investigation, I do not get relevant search results under Google :(. Thanks a lot

• How to make the cursor shape dependent on the current Vim mode using iTerm2 on OS X and zsh

  - by i0n

  I am using zsh and iTerm2 to edit with Vim. I really love the integration and portability, and because of that I have chosen not to use MacVim. But.... I can't work out how to get my cursor to change from a block to a line when in Vim's insert mode. I've been lead to believe that it's not possible by standard means, but people seem to think that it is possible using zsh. I've done as much Google searching as I can take without an answer, any help or advice would be greatly appreciated.

• Get percentage free space on database volumes w/ SQL Server 2005?

  - by Allen

  I am currently using SQL Server 2005 and (undocumented I believe) master..xp_fixeddrives to get free space on my database volumes as part of my monitoring. However, this only gives me an absolute number of MB free. What I really need is percentage free. Is there another way in SQL Server 2005 to get this? If not, is there some other light-weight way to get it? If I can, I want to avoid installing a Java JRE, or Perl, or Python on my database server. Perhaps vbscript, or a small Windows executable on the file system? Yes, I know I can Google this, and I have. It looks like there are a few ways to accomplish it, and I'm curious how my DBA brethren have handled this.

• Can't select text with mouse in Word / Office 2007

  - by asc99c

  I'm having a very weird problem here for the last few months. In Word, and in fact all programs from the Office 2007 suite, I can't drag the mouse pointer to select text. I can click at a point in the text and the cursor moves correctly to that point. If I double click, the word under the cursor is selected, and triple clicking selects the whole line. However if I hold the mouse button down and drag the mouse, no text is selected. Occasionally the problem disappears and everything works fine, but it then reappears a few minutes later. Text selection with the mouse works everywhere else (Firefox, PuTTY, OpenOffice), just not in Office. The only addins are Google Desktop Office Addin, and Person Name (). For info it is Office 2007 SP3, running on Windows 7 64-bit.

• Is it better to have multiple domains for cities or one single TLD?

  - by Brett

  I make websites for small businesses, and for some reason business owners love to have several domains with the same website but the TLD containing the city name. For example: 1. smallbizname.com 2. clevelandsmallbizname.com 3. columbussmallbizname.com 4. cincinnatismallbizname.com ... and so on. I've seen questions about localization per country aspects, but this is a much smaller scale, so I don't think the same rules apply. The problem I have is the companies never want to write separate content per domain, just have the same website hosted several times at each domain. I feel this probably hurts SEO for two reasons: 1. Traffic gets scattered throughout domains, could be boosting just one domain. 2. Duplicate content penalty because the content is identical. My question boils down to this... Should I redirect all the city domains to the main business name domain, or does having these separate sites help to rank better per city? And if they are redirected, how does google rank the redirects? Thanks for any input on this issue!!

• WIFI/LAN not working after Installing Ubuntu 13.10

  - by user183025

  I can't connect to my WIFI after installing Ubuntu 13.10. I tried re-installing it three times (thinking that I did something wrong during the installation) but I still can't connect to my WIFI. It just gives me the message that I'm offline and that I can't connect to my WIFI. I also tried connecting to the internet using LAN cable but with the same results. I tried google but it seems that there's no solution to this yet.... Anybody knows how to solve this? Thanks!

• Could crosslinking using very general anchor texts be a reason for a drop in rankings?

  - by webmasters

  I have crosslinked 20 sites and I thought I have been penalized for this, asked this question and some experienced members told me maybe that crosslinking may not necessarily be the reason. The sites are on same host, different C class IP and every site in linked to each other. Each site targets long tail kewords. Site 1 - BMW Used Cars - and my area Site 2 - WW Used Cars - and my area And so on... When I crosslinked them (in the sidebar), I did it for the users; instead of repeating the terms used cars and my location over and over (since my users are targeted) I just crosslinked them using the brand: BMW, WW. Targeting locally, my niches are not overly competitive, so I did not need to many external links to rank on various positions on the 1st page. I'm thinking that when I chose to link using only the brand, google might have thought I wanted to actually rank for BBW and WW, hence the drop in my targeted local traffic. Could this be? I now have no-followed the links and I am noticing a slight recovery, but if it's not a interlinking penalty it would be a shame not to benefit from my links.

• What software can I use to get statistics about the programs I use most? [closed]

  - by pinouchon

  I am looking for software that reports statistics about my program usage over time. It should display output something like this (numbers are made up): Program usage today: Youtube (Chrome) 42:10 9.42% NetBeans 30:52 6.33% Google search (Chrome) 12:03 3.20% Windows explorer 5:43 1.54% Putty 2:23 0.89% ? ? ? Features I look for: Advanced statistics: ability to view a chart, to see statistics today, this week, this month. Program usage should be based on the title of the active window. The time where the user is idle shouldn't count. Ability to group some windows title together, for example, I want to group titles as Stack Overflow and * - Stack Overflow together, same thing for every website and explorer windows. Do you know a program that does something similar?

• Font problems after changing non-Unicode locale to Japanese

  - by Kawa

  I recently set my system locale for non-Unicode programs to Japanese and switched it back to American English shortly afterwards. Now, just about all my non-Unicode programs use a larger dialog font without any anti-aliasing instead of Segoe UI 9, as if running on a Japanese locale. One in particular has them switched, using Segoe UI when running on a Japanese locale (be it AppLocale or system) and the Japanese font on American English! Reinstalling that particular program, as a Google search suggested, didn't do anything but reset the toolbar positions. Using Windows 7 Home Premium, and quite confused by all this.

• Hot swap in Ubuntu Server not working

  - by druciferre

  I am running Ubuntu Server 10.04 (lucid lynx), and I just purchased a hot-swap compatible hdd bay and installed it. When I insert a hot-swappable SATA drive, the drive does not show up after running ls /dev/sd?. If I reboot the server, then after it comes back up the drive appears. I have checked /var/log/messages and nothing shows up when I insert the drive, only after rebooting. I have tried the following: $ sudo echo "0 0 0" > /sys/class/scsi_host/host4/scan $ sudo partprobe` $ sudo udevadm trigger Every answer I've found searching Google was one of the things I listed in "I have tried..." and I don't really know what to do at this point. Does anyone know why this occurring?

• How do I set up disk quotas over LDAP on CentOs?

  - by Noxshun

  I've been google-ing for some time and I haven't been able to find any resources or hints on the subject. I am wondering if it is possible to do so, if so how? Any nudge in right direction will be appricated. I do know that if you download and install "Linux Quota" from source, you'll get some perl scripts which are supposed to aid with the matter. But there is as far as I know absolutely no good documentation to help you along the way. I am also running a NFS server from the same machine. Note: This is for a university assignment, so I might be totally stupid for asking this question. I am trying to explore the options. If there is a better way of solving this, please do tell. Edit: Here is a link to the site of Linux Quota. They do include a LDAP schema, so it should be possible.

• Trojan infection help please

  - by brandon

  Hey, I was browsing some websites and somehow obtained a trojan through some sort of silent download. Google Chrome started acting funny and wouldn't load web pages and neither would internet explorer. Only Firefox worked. I rebooted my computer and as usual logged into my email account as well as my bank account online completely forgetting about the infection. Could my information have been sent to the person or people or wrote the trojan? I downloaded Zone Alarm and took care of the issue, I'm just worried about when I absentmindedly logged into my email account and bank account online while I was infected.

• What is the average page size for single page application (SPA)? [on hold]

  - by Emmanuel Istace

  I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA? As this is the whole website, do you think it's acceptable? Is lazy load (for images) a solution? What will be impact for SEO ? Is the "200kb rule" of google still relevant? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs? Can a caching strategy be an answer?

• OpenXDK Questions

  - by iamcreasy

  I was strolling around XBox development. Apart form buying a DevKit from Microsoft, another thing got my attention is called, OpenXDK which stands for Open XBox Development Kit. From their main site its pretty obvious that there hasn't been any update since 2005 but digging a little deeper, I found that in their project repository is was being updated. Last time stamp was 2009-02-15. Quick google search said, its not actually really on a good place to poke around. Many and MANY features are absent. Being a hobby project I perfectly understand. But, those results are quite old. The question is, is there anybody who has any experience with OpenXDK? If is, that is it possible to shade some light on this? about its limitations? Is this a mature project? How's the latest version and what's it capable of doing? Or should I just stay away from it?

• Block complete network access for one local user

  - by tumchaaditya

  Well, this is quite trivial question but I could not find a satisfactory answer even after trying many search queries both here and on Google. I want to share my PC with my room-mate. And I don't want him to access ANY network(LAN included). So, I can create an account for him and block network access for the same. I would prefer avoiding any third-party tools as far as possible. It's a simple home PC hooked up to a router for internet. No domain and other stuff. (Technically, guest account can achieve this. But somehow, the guest account on my PC has network access!)

• Highlight identical strings in vi(m)

  - by Boldewyn

  One feature of Notepad++, which I find really useful and haven't found elsewhere, is the highlighting of other text that is identical to the one currently selected. Is there something similar possible with vi(m)? (Of course, there is. But how do I achieve it?) That is, any of those: If I am in Visual Mode and have text selected: Highlight identical text If I have searched /foo, highlight all instances of foo. If I am at the beginning of a string (series of characters, numbers or underscores), highlight all other matching strings (prefered solution). The last one is similar to the closing parentheses matching and IMHO the most useful. Edit: For my second use case, I found a solution (that is, Google found it...): :set hls However, the others remain.

• How can I disable my laptop's built-in keyboard?

  - by sam

  I have a HP Compaq Presario C700 laptop with Windows 7 installed on it. My laptop's keyboard is not working properly; some keys never work and some keys will keep on pressing. I've formatted the OS but it didn't solve my problem. I bought an external USB keyboard and it works well. As some keys in the built-in keyboard activate themselves, I still couldn't work effectively. After searching Google I tried the following steps to disable the built-in keyboard: Disabled keyboard drivers: This didn't work because when the system reboots, the driver gets installed again automatically. Installed irrelevant driver for keyboard: This failed - I couldn't install the driver. After rebooting it installed the correct driver automatically. Can anyone help explain how I can temporarily uninstall my built-in keyboard? I don't want to remove it manually (removing the hardware cable).

  I have asked question on http://stackoverflow.com/questions/9868426/i-need-to-know-which-email-server-i-have-to-use and someone tell me my question would be better on serverfault. I know that this is a common question and asked many times. but there are so many available mail servers that i am not able to decide the one. Kindly tell that which is the Secure, Stable and fast open source mail server for Centos or Redhat Server. Is there any guide which can be used to deploy the mail server with all its components e.g. smtp, pop3, imap, spam, calender server, antivirus, DNS Setting. Currently I'm using sun messaging V6 which installed on Solaris 10 and my boss ask me to make a report for the best mail server today in the marketing? I tried to have a look on Google but I couldn't find interesting information for my report. Any advice would be appreciated.

• How do I change the console resolution of Ubuntu 9.10 Server running on VMWare?

  - by Raam Dev

  I'm running Ubuntu 9.10 Server in VMWare Fusion (on a Mac) and I'm having trouble changing the console resolution. It seems to be stuck on 640x480. Ubuntu 9.10 uses Grub2, so there is no /etc/grub/menu.lst. I tried adding vga=791 to the kernel parameters (both during boot and by adding it to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and then running update-grub2) and neither had any effect. When using vga=791, grub says that vga=791 is depreciated and that I should use gfxpayload=1024x768x16,1024x768 instead. However, that also does absolutely nothing. I have a feeling this problem is specific to running Ubuntu 9.10 in VMWare, but Google hasn't turned up anything.
