The idea's a clever one. Take your Windows desktops, virtualize them in your data center with VMware, and then access them with Linux thin client machines. VMware View Open Client lets you connect from a Linux desktop to remote Windows desktops managed by VMware View. It is available under the GNU Lesser General Public License version 2.1 (LGPL v 2.1). En klient med öppen källkod lanseras till VMware View. Det ska ge företagets parners möjlighet ta fram individuellt anpassade lösningar. VMware View låter ett företags anställda arbeta med sitt personliga skrivbord, oavsett vilken klient i nätverket de använder. Bolagets IT-avdelning administrerar och lagrar användarnas personliga inställningar direkt i datacentret. Genom att dela med sig av källkoden i klientmjukvaran hoppas WMware ge sina parners möjlighet att vidareutveckla och anpassa åtkomsten till View.

There are many situations where a file has been deleted (typically by an overnight log-cleaning process), yet the inode is still held open by a process reading from, or writing to, it. Recovery of such a file is simple, regardless of whether it is on ext2, ext3, reiserfs or any other filesystem. When a file is deleted in linux, it is simply 'unlinked'. The inode, which contains the file's data, is not deleted until all processes have finished with it. This is why processes can carry on writing to deleted files. (Incidentally, this is why linux can be upgraded without requiring a reboot. Programmes, which have shared libraries open, carry on using the old versions of shared libraries until they finish.)

A Better Way to Deliver Value Added Services With the rise in broadband users, people continue to consume and share increasing amounts of digital content each year. The time and money invested in personal photos, home movies and in content purchased digitally is significant and continues to grow. Network connected consumer electronics devices, smart phones and social websites have emerged to help consumers share and access their personal content in the home and over the Internet. With the growth in digital content, there is a need for services to secure, manage and share content simply and reliably. Today digital home services such as media servers, file sharing and backup software all need to be installed on a PC. A plug computer is a small, powerful computer that connects to an existing network using Gigabit Ethernet. This type of device eliminates the need for an always-on PC in the digital home to access these services.

How the Linux kernel works In depth: My trusty Oxford Dictionary defines a kernel as "a softer, usually edible part of a nut" but offers as a second meaning: "The central or most important part of something." (Incidentally, it's this first definition that gives rise to the contrasting name 'shell', meaning, in Linux-speak, a command interpreter.)

Zentrales Konfigurations Management

Puppet, the configuration management solution. The Puppet framework provides a means to describe IT infrastructure as policy, execute that policy to build services then audit and enforce ongoing changes to the policy. Puppet helps accomplish the goal of a hands-off, automated infrastructure.  The benefits of automated infrastructure go beyond policy-enforced consistency and auditing.  The impact of hardware failure and other disaster scenarios can be mitigated, as services can be quickly restored by Puppet. In conjunction with virtualizaton, the ability to reliably create new systems running consistent services can be leveraged to create autoscaling applications as well as test systems identical to production environments.

Linux only: Just over a year ago, we offered a semi-easy way to rip DVDs in Linux to video files. Had we been up on AcidRip, we could've saved ourselves about 900 words. Okay, that's a bit of overstatement, especially if you like to have a lot of fine-grain control over how your video files turn out. But AcidRip works as a two-click ripper if you want it to. Load a DVD in your drive, start AcidRip, hit the "Load" button in the upper-right corner, then hit "Start" at the bottom. After a good wait, the kind you're used to if you've done this before, an .AVI file of the longest track on your DVD arrives in your home directory, looking like the standard-quality, 700MB-ish video we hear is all over the file sharing networks these days.

I've noticed on brainstorm.ubuntu.com that there are a few people who would like to have an ubuntu-desktop-minimal edition instead of the default ubuntu-desktop which bundles software that not all of us use. I'm one of those users who likes to build his system from the ground up, so I wrote this simple post-install script which will give you a complete minimal desktop. After running this script your system will look the same as a fresh install of ubuntu just without all the added software. The first step to accomplish this is install a base system either using the Ubuntu Minimal CD (I use this along with my personal repository to create quick installs) or you can use the Ubuntu Server edition. Once the base installation completes, login and run the following script, then reboot.

The GNU xargs command that comes with Linux and the one distributed with FreeBSD support a -P option through which one can specify the number of jobs to run in parallel. Using this flag (perhaps in conjunction with -n to limit the number of arguments passed to the executing program), makes it easy to fire commands in parallel in a controlled fashion.

The xargs -P flag can also be useful for parellelizing commands that depend on a large number of high-latency systems. Only a week ago I spent hours to write a script that would resolve IP addresses into host names in parallel. (Yes, I know the logresolve.pl that comes with the Apache web server distribution, and the speedup it provides leaves a lot to be desired.) Had I known the -P xargs option, I would have finished my task in minutes.

A library implementing PEP 3143 for creating well-behaved Unix daemon processes

This library implements the well-behaved daemon specification of PEP 3143, "Standard daemon process library". A well-behaved Unix daemon process is tricky to get right, but the required steps are much the same for every daemon program. A DaemonContext instance holds the behaviour and configured process environment for the program; use the instance as a context manager to enter a daemon state.

Here are a few scripts, that I find really useful for speeding up my web development time. I’ve been building up this list as I needed to use them - so they maybe a little raw. For example often clients send me images with filenames that don’t match my naming standard, so running the appropriate script really helps keep me focussed on the job in hand and not waste too much time reformatting filenames etc.

An operating system for PCs that is tied to its Chrome Web browser. Called the Google Chrome Operating System, is initially intended for use in the tiny, low-cost portable computers known as netbooks. “Speed, simplicity and security are the key aspects of Google Chrome OS. “We’re designing the OS to be fast and lightweight, to start up and get you onto the Web in a few seconds.” Would be released online later this year under an open-source license, which will allow outside programmers to modify it. Google Chrome OS will run on both x86 as well as ARM chips and we are working with multiple OEMs to bring a number of netbooks to market next year. The software architecture is simple — Google Chrome running within a new windowing system on top of a Linux kernel. For application developers, the web is the platform. These apps will run on any standards-based browser on Windows, Mac and Linux. Google Chrome OS is a new project, separate from Android.

We all knew it was coming, but it's absolutely interesting to see proof from the horse's mouth

In this article, we'll take a behind-the-scenes look at the design and development of btrfs on many levels - technical, political, personal - and trace it from its origins at a workshop to its current position as Linus's root file system. Knowing the background and motivation for each step will help you understand why btrfs was started, how it works, and where it's going in the future. By the end, you should be able to hand-wave your way through a description of btrfs's on-disk format.

btrfs is a b-tree based fs that is cow friendly (i.e. by removing sibling links you don't have to copy whole tree on block update). Support snapshots, checksums etc. Implementation comes out of Oracle, has some commonalities with zfs.

Tcpdump is the premier network analysis tool for information security professionals. Having a solid grasp of this über-powerful application is mandatory for anyone desiring a thorough understanding of TCP/IP. Many prefer to use higher level analysis tools such as Wireshark, but I believe this to usually be a mistake. In a discipline so dependent on a true understanding of concepts vs. rote learning, it's important to stay fluent in the underlying mechanics of the TCP/IP suite. A thorough grasp of these protocols allows one to troubleshoot at a level far beyond the average analyst, but mastery of the protocols is only possible through continued exposure to them. ... for this reason I strongly advocate using tcpdump instead of other tools whenever possible.

"Intimidating erminology aside, here's what desktop virtualization means today: You can run just about any OS, Mac OS X excluded, inside any other OS. Ubuntu in Mac OS? Sure. Windows 7 within Windows XP? Why not? Windows ME within Snow Leopard? Nobody's going to stop you, I guess! And these aren't patchy, half-assed experiments we're talking about here—these are fully-functioning installations that'll connect to USB peripherals, access the internet, share files with your host OS, and run almost any software, short of 3D games. You can set up as many of these things as you want, and delete them in a matter of seconds. It's pretty great, is what I'm trying to say. Best of all, virtualization is now something you can try—and stick with—for free, thanks to software like Sun's VirtualBox. It's a free download on any platform, and it does its job spectacularly.

Sun’s VirtualBox is ideal for testing different desktop environments (for example, browser testing), but I’ve discovered it’s also great for running a test server environment. Instead of setting up Apache, PHP, and MySQL right on your desktop machine, you can place them in a virtual Linux server. That way there’s no interference with your desktop, and you can ensure that your development environment is as close as possible to your eventual deployment environment.

Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project. [09wk47]

Windows/Linux: Tired of fiddling with scanned pages to remove borders, correct alignment, and otherwise prettify them before storing or emailing them? Then Scan Tailor could be right up your alley. This free app splits two-page scans into single documents, converts text to black and white without disturbing images, and cleans stray specks off pages. Scan Tailor even gets rid of that pesky shadow down the center of a two-page scan that occurs when you lay an open book face down on a scanner.

Adobe Flash full screen acceleration concertedrxn (not verified) - May 1, 2009 @ 7:40am @ Alex RE: Adobe Flash The problem is that Adobe doesn't know how to properly check for direct rendering without crashing their code, so they check for "SGI" in the output of glxinfo instead. Essentially this means that full screen acceleration is disabled for all but nVidia cards, even when other cards are more than capable of GPU acceleration. See <http://blogs.adobe.com/penguin.swf/2008/05/flash_uses_the_gpu.html>. The good news is you can override the blacklist by adding "OverrideGPUValidation=true" (without the quotes) to /etc/adobe/mms.cfg.

Away back in the dark and backward abysm of time when GPS technology was first being made generally available (e.g., 1993), only military-grade receivers were sensitive enough to use it where there were things like buildings and trees partly blocking the sky view. The first civilian customers to actually find a use for it were people messing about in boats. Thus it came to pass that the manufacturers of marine navigation systems were the first civilians to grapple with the question of how a GPS receiver should report TPV information over a wire to a navigational computer.

The Adobe Flash Player maintains proprietary cookies called Local Shared Objects or LSO’s. LSO’s are capable of storing 100 kb’s of information for an indefinite amount of time by default. When you clear your browser history in Internet Explorer, Firefox or Opera on Windows, Linux, or OS X LSO’s are not cleared from Adobe’s local repository.

Os X

There are hundreds of applications out there from spyware cleaners to built-in browser features that eliminate cookies on the spot, and even let you set cookie policies on your computer regarding what can be stored in your machine, and for how long. I’m assuming that if you’re here reading this post, you already know all of the dangers of cookies on your computer. In all honesty, I don’t seriously believe that they’re the most dangerous form of movement or web tracking, but they can definitely be used to monitor more movements than a person should feel comfortable with.

New to Ubuntu 8.10 is a nifty seamless encryption feature. It's always been possible to encrypt individual files/folders in Ubuntu but it involved creating a key pair and then individually encrypting files. To view or edit the file, it was necessary to decrypt it and then re-encrypt it again if changes were made. Messy. The new feature creates an encrypted filestore, mounted in the Private folder in your /home directory. This is automatically locked and unlocked as you log in and out, so accessing it is seamless and transparent. Other users won't be able to access it, and it isn't possible to see its contents by booting into rescue mode. To activate the feature, just type the following two commands: sudo apt-get install ecryptfs-utils ecryptfs-setup-private Follow the prompts shown and then log out and back in again. Once the desktop reappears, you'll see a new Private directory in your /home folder, where you can save data, as with any other directory.

If you like the looks and features of Ubuntu 9.04, but want a lighter, swifter version of it, try this minimalist installation that can knock memory usage down by up to 75 percent. Ubuntu Forums user TheShiv likes to build his system from the ground up, and doesn't like a lot of software and services he'll never use. So he installs a core, bare-bones system from either the Ubuntu Server Edition CD or a Minimal CD, then, when he gets access to a command prompt and he's wired to the internet (presumably through a LAN cable, though perhaps wireless works as well), he uses two or three commands to install enough features to get a working desktop, but very little that won't be used day to day. TheShiv frames his installation as a script you can copy, save, and run, but users could also just copy the sudo apt-get -y install commands he has listed at the link below. It's been linked to by a few approving Ubuntu heads, and seems like a pretty good way to get a lower-memory, but still GNOME-b

In fact, Sugar on a Stick will work even if the computer does not have a hard-drive.

pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect. Simply put, this is a proxy server that works behind a NAT, even when the client is behind a NAT, without any 3rd party. There is no middle man, no proxy, no 3rd party, no UPnP/STUN/ICE required, no spoofing, and no DNS tricks. More importantly, the client can then connect to any host or port on any remote host or to a fixed host and port decided by the server.

Processors are described as being a certain number of bits. This normally refers to the size of the registers, although there are exceptions — such as 390 31-bit — where it refers to the physical address size. For desktop and server platforms, this number is 31, 32, or 64; for embedded devices and microprocessors, it can be as low as 4. The physical address size can be the same as the register width but could be larger or smaller. Most 64-bit processors can run 32-bit programs when running a suitable OS.

The tool is called depant ((DE)fault (PA)ssword (N)etwork (T)ool). Depant works by downloading a default password list, and then mapping out the local network to see what open services are available. Once it has a list of services, it will test each service for default passwords. Once it’s gone through each of the services, depant will determine the fastest service (as recorded in phase one) and use it to perform an optional second phase of tests with a larger (user-supplied) set of default users/passwords.

Why Stallman started, and then stopped, using the OLPC

Teaching children to use Windows is like teaching them to smoke tobacco—in a world where only one company sells tobacco. Like any addictive drug, it inculcates a harmful dependency. (Bill Gates made this comparison in a 1998 issue of Fortune Magazine.) No wonder Microsoft offers the first dose to children at a low price. Microsoft aims to teach poor children this dependency so they can smoke Windows for their whole lives. I don’t think governments or schools should support that aim.

The Perfect Desktop - Ubuntu Studio 9.04

This tutorial shows how you can set up an Ubuntu Studio 9.04 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

This article explores some of the Linux architectures that support real-time characteristics and discusses what it really means to be a real-time architecture. Several solutions endow Linux with real-time capabilities, and in this article I examine the thin-kernel (or micro-kernel) approach, the nano-kernel approach, and the resource-kernel approach. Finally, I describe the real-time capabilities in the standard 2.6 kernel and show you how to enable and use them.

"Developers hate it when a new version of a language doesn't work with the code written for older versions of that language, but for van Rossum, the radical upgrade was necessary. The language was becoming ever more weighed down by multiple ways of doing the same task, and ways of doing tasks no one ever actually did."

Typically, each new version of the Python programming language has been gentle on users, more or less maintaining backward compatibility with previous versions. But in 2000, when Python creator Guido van Rossum announced that he was embarking on a new version of Python, he did not sugar coat his plan: Version 3.0 would not be backward-compatible. Now that the first release candidate of Python 3.0 is out, with final release planned for later this month, developers must grapple with the issue of whether to maintain older code or modify it to use the new interpreter.

Windows/Mac/Linux: Free, open-source application Synkron is a powerful file-syncing utility that syncs files across platforms. The apps's marquee features include support for syncing multiple folders, automatic scheduled syncs, and restore capabilities for files that may have been accidentally overwritten during a sync. Apps like previously mentioned Dropbox boasting instantaneous sync between your PCs and the web are all the rage right now, but Synkron has its own appeal—namely that it's a local sync tool, so your files never pass through any third-party server. It also supports filtering by extension and file and folder blacklists. So while Synkron may not be up to the instant syncing standards you can expect from the likes of Dropbox, it does support complex backup schemes and is a great alternative. Synkron is free, works on all platforms.

@AlohaArleen Could it be the current worm? http://is.gd/otVx [from http://twitter.com/dc0de/statuses/1373557182]

You are only vulnerable if: * Your device is a mipsel (MIPS running in little-endian mode, this is what the worm is compiled for) device. * Your device also has telnet, SSH or web-based interfaces available to the WAN, and * Your username and password combinations are weak, OR the daemons that your firmware uses are exploitable. As such, 90% of the routers and modems participating in this botnet are participating due to user-error (the user themselves or otherwise). Unfortunately, it seems that some of the people covering this botnet do not understand this point, and it is making us look like a bunch of idiots.

I discovered that you'd never get an answer to a problem from Linux Gurus by asking. You have to troll in order for someone to help you with a Linux problem. <dm> For example, I didn't know how to find files by contents and the man pages were way too confusing. What did I do? I knew from experience that if I just asked, I'd be told to read the man pages even though it was too hard for me. <dm> Instead, I did what works. Trolling. By stating that Linux sucked because it was so hard to find a file compared to Windows, I got every self-described Linux Guru around the world coming to my aid. They gave me examples after examples of different ways to do it. All this in order to prove to everyone that Linux was better.

staple is a program that inseparably binds together the data in a file using a cryptographic mechanism known as an All-or-nothing transform. In its most basic form (when executed as staple 0), the transformation is keyless; that is, no key is required to reverse it, however all the data is required. Thus, running unstaple on the output .staple file yields the original file, but running it on any subset of the .staple file yields nothing.

[...]It has been suggested that this scenario occurs if Alice is a content producer/owner, Bob is a content piracy group, and Charlie is a user unconcerned about copyright infringement. Taking their last example: Alice could pretend to have brute-forced the key k rather than recovered from B and r, no? And is all-or-nothing so hard to do? what about making c=k xor H(Ek(m)) | Ek(m) ? You need the full data to compute the hash on the encrypted message to recover the key and decrypt the message. And you can throw away part of the key also in this scheme UPDATE: hum actually it appears that it's precisely what he's doing :-)

(The only argument staple takes is the number of key bytes to throw away; only 0, 2, and 4 are accepted currently.)"

Google is phasing out the internal use of Microsoft’s ubiquitous Windows operating system because of security concerns, according to several Google employees. The directive to move to other operating systems began in earnest in January, after Google’s Chinese operations were hacked, and could effectively end the use of Windows at Google, which employs more than 10,000 workers internationally.

Internal directive follows China hacking

quote:Employees said it was also an effort to run the company on Google’s own products, including its forthcoming Chrome OS, which will compete with Windows. “A lot of it is an effort to run things on Google product,” the employee said. “They want to run things on Chrome.” The hacking in China hastened the move.

Introducing the Google Command Line Tool - Google Open Source Blog

Ever wanted to upload a folder full of photos to Picasa from a command prompt? We did, a lot, last summer. It made us want to say: $ google picasa create --title "My album" ~/Photos/vacation/*.jpg So we wrote a program to do that, and a whole lot more. GoogleCL is a command-line utility that provides access to various Google services. It streamlines tasks such as posting to a Blogger blog, adding events to Calendar, or editing documents on Google Docs.

Lifehacker shows some uses for Google's command line interface.

With the right commands, you can turn your favorite command-line text editor into a distraction-free Google Docs app, add new events to Google Calendar, upload images to Picasa or video to YouTube, backup your Google data, and more. Here's how it works. On Friday, Google released GoogleCL, a saucy command line program that interacts with Google services from any *nix-friendly command-line prompt (on Windows, Mac, or Linux). We spent the weekend playing around with it, and now we're sharing a few of the coolest ways we've been putting it to use. What You'll Need Before you can execute any of the cool commands below, you'll need to have installed a few things to get GoogleCL up and running on your system. * Windows users, you'll want to install Cygwin. (If you're not familiar with Cygwin and how it works, check out Gina's introduction to Cygwin.) If you'd really prefer to stick with Windows' Command Prompt, you can set up GoogleCL with these instructions instead. * python-vers

Those unfamiliar with the language may hear "awk" and think of a mess of code so backwards and antiquated that it's capable of driving even the most knowledgeable UNIX guru to the brink of insanity (causing him to repeatedly yelp "kill -9!" as he runs for coffee machine).

A Ubuntu-based GNU/Linux distribution targeted on analyzing malware.

REMnux is designed for running services that are useful to emulate within an isolated laboratory environment when performing behavioral malware analysis. As part of this process, the analyst typically infects another laboratory system with the malware sample and directs potentially-malicious connections to the REMnux system that's listening on the appropriate ports.

REMnux is a lightweight Linux distribution for assisting malware analysts in reverse-engineering malicious software. The distribution is based on Ubuntu and is maintained by Lenny Zeltser.

こういうの好き // なぜ，/var や /etc が /etc や /cfg というディレクトリ名ではないのか？ http://d.hatena.ne.jp/ytakano/20100715/1279219401 – えふしん (fshin2000) http://twitter.com/fshin2000/statuses/19038677901

「Unixを使っていると，/usr が全然ユーザー用じゃなくどう見てもシステムのための物だったり，/etc が事実上設定ファイル置き場となっていたり，/var がログファイル置き場となっていたりと，名が体を現していなくて奇妙な感覚を覚える．もっと分かりやすい名前の付け方があったんじゃないかと，Unixユーザーならば誰もが思うはずだが，これに対する解答がredditに投稿されており，その内容が非常に面白かったので，軽く翻訳してみた．」

Windows: Having a full Linux operating system on a USB thumb drive is pretty neat. Having that OS customized, with your own favorite apps and all your settings intact, is far more helpful. This Windows tool makes that possible. Universal USB Installer is a stand-alone application that automates the process of downloading, formatting, and installing a Linux OS to a USB drive, as well as implementing a variable amount of "persistence." "Persistence" means that when you swap out Firefox for Chrome, change keyboard shortcuts, store files in your home directory, or make other changes to your portable Linux, they stick from boot-up to boot-up—which isn't the case with most portable Linux distributions. If you've already downloaded a Linux installation ISO and run Universal USB Installer from the same directory the ISO is in, the app will find it and use it for the installation, rather than download another copy. Most useful of all, your USB drive can still be read by Windows when you're do
