Does they kiss their mothers with those mouths?

1. Most programmers swear. They complain about hardware, other software, or their fellow developers. This serves as a distraction so that other will be less likely to notice the mistakes they themselves make. It’s not exclusive to the Linux kernel, either:

http://codeulate.com/2007/12/fcking-programming/
http://www.kuro5hin.org/story/2004/2/15/71552/7795

2. It is very unlikely they kiss their mothers. They never leave their basements, and their mothers are usually in their sixties or older, so they can’t safely go down the steps.

Okay, I admit I did something really stupid.
I’ve set up a live USB stick for Puppy linux. I decided to test out the persistence feature (complete with password and "Heavy" encryption). Everything runs perfectly up to this point. computer shuts off. I turn it back on and puppy starts unpacking itself. Everything is good.

So this is what I do:
Instead of just typing in my password I decide to drop to console.
I then realized I’m nowhere near being a developer and have no experience with the LINUX comandline–I guess windows experience doesn’t help…

I know NO commands for linux. I type "help". This doesn’t work, so I’m a little worried. I don’t know how to shut everything down properly from here.

So like a total n00b I entered the "exit" command. I’m met with this:

"Kernel panic – not syncing: Attempted to kill init!"
Here it just stops. Can I just press the power button without hurting anything? Will this damage my computer or the usb drive/files on usb?

Try this:
Hold the ALT+PrintScreen keys on your keyboard, and type:
REISUB (An easy way to remember this is it’s "Busier" spelled backwards)

If that doesn’t work, then just press the power button.
It shouldn’t harm your computer since the hard drive probably isn’t mounted or being written to.

There is a chance it can screw up files on your USB drive (Most likely the Puppy save file)

Also, to shut down your computer from the command line, do this:
shutdown -h now

Or to reboot:
shutdown -r now

These should also work:
poweroff
reboot

By Greg Kroah-Hartman

As A core member of the Linux Kernel team, Greg will show us how to write a kernel patch.

This talk will cover the steps necessary to properly compose, describe, and submit a Linux kernel patch. It will cover the basic usage of git, and how that works with the Linux kernel development cycle. Attendees should have a solid grasp of the C language, and know how to build and install, a Linux kernel from scratch (if not,reading the book, Linux Kernel in a Nutshell, free online, ahead of time would be a very good idea.)

FOSDEM (Free and Open Source Development European Meeting) is a European event centered around Free and Open Source software development. It is aimed at developers and all interested in the Free and Open Source news in the world. Its goals are to enable developers to meet and to promote the awareness and use of free and open source software. More info at http://fosdem.org

I have an upload script and it” saving the filename with the original filaname+temp name. I need it to be changed as just temp name because special characters are causing problems and if there is a spacial character in the filename browsers can not read the image.

it’s funny but all that code you pasted in there is totally irrelevant to your problem..

Anyhow I went and looked up this class for you here, http://www.xoops.info/doc/nav.html?_classes/index.html and researched the problem..

After this – $uploader = new XoopsMediaUploader

slide in this:
$uploader->setTargetFileName($value);

Where $value is the random file name you wish to use.
A very simply way to create a random string would be:
$value = mt_rand(5, 15);

Keep in mind you will need to concat the extension onto that random number!!!

This book teaches Windows developers about various Windows features and how to access them via the C and C++ programming languages. Focus is on Windows basic building blocks and the fundamental concepts required for architecting and implementing software that targets the Windows operating systems. The first three chapters provide required background on error handling, working with characters and strings, and kernel objects. Later chapters are in sections on getting work done, memory management, dynamic-link libraries, and structured exception handling. This fifth edition covers 170 new functions and features that have been introduced in Windows XP, Windows Vista, and Windows Server 2008. There is more coverage of how the C/C++ run-time library interacts with the operating system. Two new chapters have been added to explain how I/O operations work and to dig into the new Windows Error Reporting system. Richter is a software consultant. Nassare is a software architect.

http://packages.debian.org/sid/developers-reference – - (due to lack of corresponding source code). The “magic” for a recompilation-only NMU is triggered by using a suffix appended to the package version number, following the form bnumber. For instance, if the latest version you are recompiling against was version 2.9-3, your binary-only NMU should carry a version of 2.9-3+b1. If the latest version was 3.4+b1 (i.e, a native package with a previous recompilation NMU), your binary-only NMU should have a version number of 3.4+b2. ^[4] Similar to initial porter uploads, the correct way of invoking dpkg-buildpackage is dpkg-buildpackage -B to only build the architecture-dependent parts of the package. 5.10.2.2. When to do a source NMU if you are a porter Porters doing a source NMU generally follow the guidelines found in Section 5.11, Non-Maintainer Uploads (NMUs) , just like non-porters. However, it is expected that the wait cycle for a porter’s source NMU is smaller than for a non-porter, since porters have to cope with a large quantity of packages. Again, the situation varies depending on the distribution they are uploading to. It also varies whether the architecture is a candidate for inclusion into the next stable release; the release managers decide and announce which architectures are candidates. If you are a porter doing an NMU for unstable, the above guidelines for porting should be followed, with two variations. Firstly, the acceptable waiting period — the time between when the bug is submitted to the BTS and when it is OK to do an NMU — is seven days for porters working on the unstable distribution. This period can be shortened if the problem is critical and imposes hardship on the porting effort, at the discretion of the porter group. (Remember, none of this is Policy, just mutually agreed upon guidelines.) For uploads to stable or testing , please coordinate with the appropriate release team first. Secondly, porters doing source NMUs should make sure that the bug they submit to the BTS should be of severity serious or greater. This ensures that a single source package can be used to compile every supported Debian architecture by release time. It is very important that we have one version of the binary and source package for all architectures in order to comply with many licenses. Porters should try to avoid patches which simply kludge around bugs in the current version of the compile environment, kernel, or libc. Sometimes such kludges can’t be helped. If you have to kludge around Compiler bugs and the like, make sure you #ifdef your work properly; also, document your kludge so that people know to remove it once the external problems have been fixed. Porters may also have an unofficial location where they can put the results of their work during the waiting period. This helps others running the port have the benefit of the porter’s work, even during the waiting period. Of course, such locations have no official blessing or status, so buyer beware. 5.10.3. Porting infrastructure and automation There is infrastructure and several tools to help automate package porting. This section contains a brief overview of this automation and porting to these tools; see the package documentation or references for full information. 5.10.3.1. Mailing lists and web pages Web pages containing the status of each port can be found at http://www.debian.org/ports/. Each port of Debian has a mailing list. The list of porting mailing lists can be found at http://lists.debian.org/ ports.html . These lists are used to coordinate porters, and to connect the users of a given port with the porters. 5.10.3.2. Porter tools Descriptions of several porting tools can be found in Section A.7, Porting tools .5.10.3.3. wanna-build The wanna-build system is used as a distributed, client-server build distribution system. It is usually used in conjunction with build daemons running the buildd program. Build daemons are “slave” hosts which contact the central wanna-build system to receive a list of packages that need to be built. wanna-build is not yet available as a package; however, all Debian porting efforts are using it for automated package building. The tool used to do the actual package builds, sbuild is available as a package, see its description in Section A.4.4, sbuild . Please note that the packaged version is not the same as the one used on build daemons, but it is close enough toreproduce problems. Most of the data produced by wanna-build which is generally useful to porters is available on the web at http:// buildd.debian.org/. This data includes nightly updated statistics, queueing information and logs for build attempts. We are quite proud of this system, since it has so many possible uses. Independent development groups can use the system for different sub-flavors of Debian, which may
