• What is a good partitioning design/scheme for a multi-boot *nix system?

  - by static

  I'm planning to install Debian on my server. I would like to design the partitioning scheme in such a way, that I could install one or more other *nix distributives on that. So, reading many articles I think this scheme could be a good one for the initial idea of multi-boot: /grub /swap /LVM VG1 (for OS1) -> /boot (LV1) / (LV2) /tmp (LV3) /var ... /var/log /home /LVM VG2 (for OS2) -> /boot / /tmp /var /var/log /home ... (other distros) /LVM VG0 (for data) -> /data (LV1) But I'm confused a little bit now: what should be the labels for these partitions (unique or not) and what should be the mounting points looking as (/home (OS1) mounted to /home as well as /home (OS2)...)?

• Hello PCI Council, are you listening?

  - by David Dorf

  Mention "PCI" to any retailer and you'll instantly see them take a deep breath and start looking for the nearest exit.  Nobody wants to be insecure, but few actually believe that PCI does anything more than focus blame directly on retailers.  I applaud PCI for making retailers more aware of the importance of security, but did you have to make them PAINFULLY aware?  POS vendors aren't immune to this pain either as we have to undergo lengthy third-party audits in addition to the internal secure programming programs.  There's got to be a better way. There's a timely article over at StorefrontBacktalk that discusses the inequity of PCI's rules, and also mentions that the PCI Council is accepting comments until April 15th. As a vendor, my biggest issue with PCI is that they require vendors to disclose the details of any breaches, in effect "ratting out" customers.  I don't think its a vendor's place to do this.  I'd rather have the trust of my customers so we can jointly solve the problem. Mary Ann Davidson, Oracle's Chief Security Officer, has an interesting blog posting on this very topic.  Its a bit of a long read, but I found it very entertaining and thought-provoking.  Here's an excerpt: ...heading up the list of “you must be joking” regulations are recent disturbing developments in the Payment Card Industry (PCI) world. I’d like to give [the] PCI kahunas the benefit of the doubt about their intentions, except that efforts by Oracle among others to make them aware of “unfortunate side effects of your requirements” – which is as tactful I can be for reasons that I believe will become obvious below - have gone, to-date, unanswered and more importantly, unchanged. I encourage you to read the entire posting, Pain Comes Instantly, and then provide feedback to the PCI Council.

• Clipboard replacements (Ditto, ClipX) stopped working in Windows 7

  - by Bassam

  Over the past few days, I've noticed that the clipboard replacement application I use (Ditto) isn't working any more. Specifically, it isn't copying items to its list. It still shows the history of items copies before, but doesn't add any new items. I am still able to paste past items, so the program is still functional. It will work for a while after quitting and restarting the program, but then it will soon stop getting new items again. I've tried using ClipX, another clipboard replacement app, and that doesn't get new items either. This leads me to think this is a Windows problem. I'm on Windows 7, 64-bit. Is anyone else having this problem? Any ideas on what might be causing it? Update: I've found that if I Disconnect from the clipboard, then Connect to clipboard again, then it works for a while, but stops collecting items again after 15 mins.

• Buffer System For Items

  - by Ohmages

  I am going to reference this image of what I want to accomplish in JavaScript. This is the Diablo buffer system. This question may be a bit advanced (or possibly not even allowed). But I was wondering how you might go about implementing this type of system in a JavaScript game. Currently to implement such a system in JavaScript escapes me, and I am turning to SO to get some suggestions, ideas, and hopefully some insight in how I could accomplish this without being to costly on the CPU. Some thoughts of mine for implementing such a system would be to: Create DIVS within a DIV that hold each position of the inventory Go through each item you own in a container and see which DIV it belongs to Make said item images the DIVs image This type of system might possibly work if ALL items were 1x1, but for this example its not going to work out. I am at a complete lost of ideas how to even accomplish this. Although, maybe rendering directly to the canvas and checking mouse cords could work, there would more than likely be A HUGE annoyance when checking if other items are overlapping each other (meaning you cant place the item down, and possibly switching item with the cursor item ). That said, what am I left with? Do I need to makeshift my own hack system with messy code, or is there some source out there (that I don't know about) that has replicated this type of system in their own game. I would be very grateful to get some replies on how you might go about doing this, and will accept answers that can logically explain how you might implement such a system (code is not required). P.S. Id like to use pure JavaScript, and nothing else (even though it might be "reinventing the wheel", I also like to learn).

• Cleaning Up After Chrome

  - by Mark Treadwell

  I find Google Chrome, which I have no interest in, is continually getting installed on machines in my house, mostly due to Adobe Shockwave bringing it along as an install package. (Family members are agreeing to the download, not realizing the Chrome is getting dropped as well.) My major issue after uninstalling Chrome is that you can no longer click on links in Outlook emails. There is a lot on the web about this, and Google has not been proactive at fixing their uninstaller. I have now added a registry file to my Win64 systems to reset the problem registry keys and clear the error. This registry file is pretty simple. It merely resets HKEY_CURRENT_USER\Software\Classes\.htm, HKEY_CURRENT_USER\Software\Classes\.html, and HKEY_CURRENT_USER\Software\Classes\.shtml back to their default values of "htmlfile". Chrome takes over the handling of these file extensions because its default install is to make itself the default web browser. The Chrome uninstalled fails to clear/reset them. In troubleshooting this, I looked in my registry based on the web info on the Chrome uninstall problem. Since my system had never had Chrome installed, my registry did not have the problem keys. To troubleshoot, I installed (ugh!) and uninstalled Chrome. Sure enough, Chrome left the expected debris with a value string of "ChromeHTML.PR2EPLWMBQZK3BY7Z2BFBMFERU" or something similar. Resetting these values fixed the problem. I see that Chrome leaves quite a bit of debris behind in the registry. I guess it is creating the keys then leaving them behind, even though their presence (with bad data) subsequently affects operations.

• What do YOU want to see in a SharePoint jQuery Session?

  - by Mark Rackley

  Hey party people. So, as you have probably realized by now, I’ve been using quite a bit of jQuery with SharePoint. It’s pretty amazing what you can actually accomplish with a little stubbornness and some guidance from the gurus. Well, it looks like I’ll be putting together a SharePoint jQuery session that I will be presenting at a few conferences. This is such a big and broad topic I could speak on it for hours! So, I need YOUR assistance to help me narrow down what I’ll be focusing on. Some ideas I have are: How to even get started; how to set up SharePoint to work with jQuery What third party libraries exist out there that integrate well with SharePoint How to interact with default SharePoint forms and jQuery (cascading dropdowns, disabling fields, etc..) What is SPServices and how can you use it When should you NOT use jQuery What do YOU want to see though? This session is for YOU guys, not for me. Please take a moment to leave a comment below and let me know what you would like to see and learn. Thanks, and I look forward to seeing you in my sessions!! Mark

• Setting up scripts in Amazon EC2 Cloud

  - by racket99

  Hello, I am currently running a few perl and python scripts on a windows pc and would like to port over to the Amazon EC2 servers running 64-bit LINUX. The scripts are basic web scrapers that go to a variety of websites, get data and then save daily as csv files. I would like to install these in the cloud and get them running in an automated way so that they will run without my intervention. Also given that I don't want to lose all the data if the instance crashes, I should also upload the csv files to Amazon S3. Any idea how I can do this? I am not terribly versed in LINUX nor do I know Perl/Python well. What is the best way for me to tackle thi

• Connecting PPTP VPN with Ubuntu 9.10

  - by Christian P.

  I have an ubuntu machine that I wish to connect to a VPN and have traffic routed through that. So far I have installed the pptp-linux package and tried my hand at configuring it manually as well as using pptpsetup. I am using Ubuntu 9.10, but regardless of the method I get "Couldn't find MPPE kernel support". Searching a bit for the problem seems to reveal that Ubuntu DOES come with MPPE kernel support (and has done for quite some time). If anyone can figure this out, you'd be a real lifesaver!

• Do you find using a VPS worthwhile?

  - by Grant Palin

  I am currently on shared hosting, and have been recently looking at the idea of switching to a VPS instead. From what I have gathered, a VPS allows you more control over your server setup. But at the same time you have to set it up yourself, and maintain it. This is the bit I am asking about... Despite the power and flexibility you get from using a VPS, you have to take care of it yourself. Is it worth it? Some context: I am primarily a Windows user, but have been tinkering with various Linux distros off and on for several years. I know enough about Linux to get by, or to be dangerous - take your pick. I've also done some tinkering on my current host, but have no serious sysadmin experience. There's always a first time!

• How to remove the dlinksearch browser search hijack

  - by Bish

  Hi Gang, For the last few weeks all the machines on my home network are having the same problem whilst browsing the internet. When the user enters an invalid URL in the browser address bar, instead of the default browser behaviour, the request is sent to http://www1.dlinksearch.com/. As far as I can tell this is all machines and all browsers. It is so consistent I am wondering whether it has anything to do with our router. We use a DLink DIR-655 router so maybe the clue is in the name :) Anyhow, I cannot figure out how to disable/remove the offending behaviour. I've checked hosts files, spyware, AV etc. etc. Anybody have any ideas? Paul P.S. Apologies if this is not the right place to ask this type of question. I'm a bit stuck

• Which Windows OS Supports 8 GB RAM in a Laptop and Suggestions for a Better Laptop for Personal & De

  - by Ellen

  I am about to purchase a laptop and have zeroed on the following two of them. Toshiba L500-ST2544 Toshiba L505-ES5034 The Common Specification for both of them are as follows - RAM - 4GB DDR3 Memory HDD - 320 GB Processor - Intel® Core™ i3-330M Processor WebCam and Mic - Available HDMI Port - Available Numeric Key Pad - Available Windows 7 (64 bit) Home Premium Now, the only difference between ST2544 and ES5034 is that, the ST2544 has a maximum of 2 slots with 2 GB in each. So, you can have a max of 4 GB RAM in that. The ES5034 can support 8 GB RAM, so, in a couple of years, if I want to add another 4 GB RAM I will be able to do it. The price for ST2544 is USD 629.00 whereas, the price for a ES5034 is USD685. A difference is USD 55.00 (not a major amount, but still something extra). Is it worthwhile going for the ES5034? Which Windows Operating System supports 8 GB of RAM?

• Automatically keep your local git repos clean

  - by kerry

  Most developers using git are probably aware of a command ‘git gc’ that has to be run from time to time when you notice your git commands are running a little slow. This command cleans up your git repo and makes sure everything is nice and tidy. If you have not run this command lately, you will notice a huge performance increase in your git commands after running. It’s a bit annoying to have to run this command when you notice that your git performance is suffering. The command also takes a while if you have not run it recently. With this in mind, I decided to create a method to automatically run this command from time to time. So I decided to overload cd similar to how rvm does. All you have to do is paste the method in your .profile file and it will run the command every time you enter a directory with a git repo. You’ll notice a little pause when entering the directory, it’s not insufferable but if you would prefer, you can add an & to the end of the command to have it run in the background. I chose the pause over the pid output of the background command. Here it is in all it’s glory. View the code on Gist.

• Cannot Boot, How to recover

  - by Kendor

  Am running 11.10 64-bit with Gnome-shell. Something happened late Friday whereby my machine never gets to the login screen. I do get to an Ubuntu splash logo, after that I get a text screen that it hangs on. The screen is referring to issues with mounting various network resources, including VMWare and also some references to my NAS that are in fstab. If I hit "esc" I can get to the GRUB menu and into recovery console. If I try to do a file system check, I run into a similar error screen that I see when trying to boot normally. A possible clue here is that during my last good session I made some mods to the /etc/hosts file to reference another system which I'm connecting to with Synergy. I don't believe I have hardware issues as I'm able to boot properly with a Live USB and connect to my network/Internet. A few more tidbits. I have regular Dejadups backups on my NAS. I have a good Clonezilla whole drive image which is 4-6 weeks old.. My home is encrypted. I thought I'd try blowing away my hosts file via live USB, but when I mounted the hard drive everything was read-only and I couldn't figure out how to replace it. P.S. I logged in via CLI and modded the host file to remove the entry I'd made, to no avail. System continue to gets stuck on the following: CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel version 3.1s Would love some sober advice on how to attack this.

• Weird system freeze. Nothing works keyboard/mouse/reset button - Ubuntu 12.04 64bits [closed]

  - by Simon

  I have fresh PC: i5 3570K with Intel 4000 onboard ASrock Z77 Extreme4-m 8GG RAM - Adata 1333Mhz... 1TB Seagate drive 7200rpm I've also fresh systems - Ubuntu/Win7 and today there was something strange. Ubuntu twice just freezed. Everything stopped, even keyboard and mouse wasn't responding. Even RESET button didn't work. Right now memtest is running, but I'd like to know, where else can i look for cause. Can it be software fault if even reset isn't working? Only long reset pressing rebooted PC... I'm a bit confused. Or should I test components - CPU, motherboard, disk. Which logs in Ubuntu should I check to diagnose cause? EHm I had few adventures with this PC already. Shipped motherboard was broken (ASrock Z68 Extreme3) and had old bios, so I had to contact with reseller, replace it and at the end decided on Z77, but everything took 3 weeks, so I have bad feelings... Edit: Both freezes were during editing something in gedit (it can be coincidence) and after few updates today - when memtest is end I'll check what was updated

• How to use graphical line drawing characters with Midnight Commander on OS X under ssh?

  - by Sorin Sbarnea

  I discovered that when I do ssh to a machine using OS X 10.6 and use mc I do not see the graphical line drawing characters. This does not happen if I open terminal and start mc. I'm connecting using putty configured to use xterm-color, configuraton that works just fine if I do ssh to a linux machine. The mc from OS X is version 4.7.0 (installed using macports). What locale returns: LC_CTYPE="C" <== ssh LC_CTYPE="UTF-8" <== Terminal.app ssh: mc display bits shows: 7-bit ASCII (changing does not help, it defaults to the same value) Terminal.app: mc display bits shows: UTF-8 The environment shows TERM=xterm-color in both cases Terminal.app and ss but mc looks different. I filed a bug to mc with this information at http://www.midnight-commander.org/ticket/2339

• Making python run on my webserver

  - by richzilla

  Hi all, im getting a bit stuck regarding options for running python scripts on my server. From the research ive done so far, i can see i need to modify apache slightly to run python scripts, by using either mod_wsgi or mod_python. Two issues i have: mod_python doesnt appear to be maintained anymore (last release, 2007) mod_wsgi appears to require modification of my httpd.conf file on a per application basis. What im wanting to know, is there a way of getting python scripts to run in the same way as php, i.e. just by going to index.py etc... or is it more involved than that? At present im just trying to set it up on my xampp install. Any help would be appreciated.

• Help desk software - specific feature needed

  - by LunchMoney

  I am having a hard time finding help desk software that allows for drop down hyperlink selection during ticket creation. The situation is that we do external support for client systems and connect via remotely anywhere or logmein. Right now we use a poorly modified php based system that has a customer drop down menu and then a site drop down list that is then parsed by a bit of java script which opens a url. What I am looking for is the ability to store customer site URL information in the database and during the creation of a ticket be able to select the customer name and then select the site there by placing the corresponding site URL in the ticket. The support tech will then be able to click on this link to access the customer's site. Has anyone used or seen help desk software with this feature?

• Ubuntu 12.04 and Nvidia GTX 550 Ti

  - by Jim

  OK I'm currently trying to install Ubuntu x64 Server 12.04 onto the following machine: Intel Core i5-2320 3.0GHz LGA1155 6MB 8 GB DDR3 RAM, Gigabyte Z68P-DS3 S1155 Intel Z68 DDR3 ATX M/B, OCZ 60 GB SSD, 3x Samsung 2TB drives in a RAID 5 array (via M/B) Now what I think is causing the issue is the following: EVGA GeForce GTX 550 Ti 951MHz 1GB PCI-Express HDMI FPB As the server CD works in text mode I haven't had a problem with actually installing Ubuntu. Partioned with: 1GB /boot SSD, 59GB / SSD, 10GB swap RAID5, ~4TB /home RAID5 On a straight boot, you briefly see the GRUB menu, followed by a blank screen. The keyboard and mouse blink as they are initialised but no sign of life from the screen. Followed by a bit of research (otherwise known as google) ... Booted in quiet splash nomodeset Now I have a fully working linux distro at the command prompt. I then proceed to try and update the nvidia drivers with apt-get (after updating repositories etc) and rebooting. Still the same problem. I also tried reinstalling from the CD and installing said drivers in the install process before GRUB was installed, still the same symptoms. Does anybody have any solutions? I'm at my wits end here, I bought this machine to be a linux server / tinkering machine and have just spent 4-5 hours trying to just get a basic install working.

• What is the correct root file to import to aptana from an xampp folder/existing web app or git repository?

  - by gaff

  Very noob question - all of this is new to me - not really sure how to get started. Overview: I'm taking over an existing wep project that has been developed in aptana and deployed in xampp setup - I also have access to Git repository on local directory. I want to import the web application into aptana, run it and begin updating/editing - bit of steep learning curve for me What is the best way to import? And what should I import? What should it look like in aptanan? I tried importing what I think is the root file from the git folder ("existing folder as new project")- it contains things like css, doc, img and js. This looks right to me - but might not be. Thanks, Gaff

• users unable to add registry keys to HKCU

  - by Eds

  I may not have this 100% correct so need some clarification. Are normal users on a 2003 terminal server allowed to add registry keys the their own HKCU section in the registry, or are they only allowed to edit existing ones? The reason I ask is that we have 3 keys that we need to add for each user on login. I thought it would be as simple as having a straightforward batchscript run that silently adds the keys for the user. Here is what I used: regedit.exe "C:\Documents and Settings\All Users\Desktop\example.reg" When the user runs this batch scipt, they see nothing as you would expect, but the keys are not added. If I simply run the .reg file as the user, it asks if I want to add the key, but then has an error saying there was an error accessing the registry. Do I need something a bit more complex to accomplish this task. Many Thanks Eds EDIT: Contents of .reg file Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\Security] "PromptSimpleMAPINameResolve"=dword:00000002 "PromptSimpleMAPIOpenMessage"=dword:00000002 "PromptSimpleMAPISend"=dword:00000002

• Raspberry Pi, Time Capsule Progress

  - by Richard Jones

  So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

• People != Resources

  - by eddraper

  Ken Tabor’s blog post “They Are not Resources – We Are People” struck a chord with me.  I distinctly remember hearing the term “resources” within the context of “people” for the first time back in the late 90’s.  I was in a meeting at Compaq and a manager had been faced with some new scope for an IT project he was managing.  His response was that he needed more “resources” in order to get the job done.  As I knew the timeline for the project was fixed and the process for acquiring additional funding would almost certainly extend beyond his expected delivery date, I wondered what he meant.  After the meeting, I asked him what he meant… his response was that he needed some more “bodies” to get the job done.  For a minute, my mind whirred… why is it so difficult to simply say “people?”  This particular manager was neither a bad person nor a bad manager… quite the contrary.  I respected him quite a bit and still do.  Over time, I began to notice that he was what could be termed an “early adopter” of many “Business speak” terms – such as “sooner rather than later,” “thrown a curve,” “boil the ocean” etcetera.  Over time, I’ve discovered that much of this lexicon can actually be useful, though cliché and overused.  For example, “Boil the ocean” does serve a useful purpose in distilling a lot of verbiage and meaning into three simple words that paint a clear mental picture.  The term “resources” would serve a similar purpose if it were applied to the concept of time, funding, or people.  The problem is that this never happened.  “Resources”, “bodies”, “ICs” (individual contributors)… this is what “people” have become in the IT business world.  Why?  We’re talking about simple word choices here.  Why have human beings been deliberately dehumanized and abstracted in this manner? What useful purpose does it serve other than to demean and denigrate?

• Impersonation on IIS 7.0 passes the machine credentials for Crystal Reports

  - by pknox

  On a 32-bit Windows 2008 server running the Donor2 Application in the Classic .NET Managed Pipeline mode, configured for Windows Integrated Authentication and Impersonation, all of the .NET pages are passing the authenticated user’s credentials [DomainName\UserName]. This is the correct, expected behavior. The Crystal Reports pages, instead of passing the authenticated user’s credentials, are passing the IIS Server’s credentials [DomainName\MachineName$]. One of the very frustrating aspects of this situation is that I have another server which, as far as I can tell, is configured identically. That server, when loading Crystal Reports, is passing the authenticated user’s credentials [DomainName\UserName] as expected. I have obviously missed something, but I have no idea what it could be.
