Linux Club of Peking University coreboot - the free firmware April 9th, 2016 3 / 30 LinuxBIOS v1: 1999-2000 The coreboot project originally started as LinuxBIOS in 1999 at Los Alamos National Labs (LANL) by Ron Minnich. Ron needed to boot a cluster made up of many x86 mainboards without the hassles that are part of the PC BIOS. The goal was to do minimal hardware initilization in order to boot Linux as fast as possible. Linux already had the drivers and support to initialize the majority of devices. Ron and a number of other key contributors from LANL, Linux NetworkX, and other open source firmware projects successfully booted Linux from flash. From there they were able to discover other nodes in the cluster, load a full kernel and user space, and start the clustering software. Linux Club of Peking University coreboot - the free firmware April 9th, 2016 4 / 30 LinuxBIOS v2: 2000-2005 After the initial success of v1, the design was expanded to support more CPU architectures (x86, Alpha, PPC) and to support developers with increasingly diverse needs. -

GIMP to Increase Business Productivity GIMP Or GNU Image Manipulation Programme Is a Cross-Platform, Open Source Image Editor
Focus Using GIMP to Increase Business Productivity GIMP or GNU Image Manipulation Programme is a cross-platform, open source image editor.

A copy of the license is included in the page “GNU Free Documentation License”. Libreboot on x86 uses the GRUB payload by default, which means that the GRUB configuration file (where your libreboot GRUB menu comes from) is stored directly alongside libreboot and its GRUB payload executable inside the flash chip. This means that both installing and managing GNU/Linux distributions are handled slightly differently compared to traditional BIOS systems. On most systems, it is necessary to have at least an unencrypted /boot partition (while the others, including root, may be encrypted). This is so that GRUB, and therefore the kernel, can be loaded and executed, because the boot firmware itself can't open a LUKS volume. -

Quadcore with Coreboot / Libreboot on the T500 (Hopefully the T400 As Well)
QuadCore with Coreboot / Libreboot on the T500 (hopefully the T400 as well) (Translator’s note: Unfortunately, I couldn’t get pdflatex to compile with images, so here’s the link, I’ll put lines in at least so that you can see where each image goes) I tested the quadcore-mod from here first on a T500 mainboard, but back then, the BIOS did me a great disservice, see here and read the paragraph “Why this can’t be done for the T500 and W500” at the end of the first post. Meanwhile, we got Libreboot for the T500, which is basically Coreboot without BLOBs, i.e. CPU microcode. The code differs from coreboot in certain other aspects, however I don’t know exactly. With the ROMs offered for the T500, Quads don’t work either. Finally, I got to actually using a Pandaboard to debug Libreboot’s boot process with a Quad-core installed. The boot process hangs when the third CPU is to be initialized. Looking at the code, I found out that the kconfig data is built to the original specs. In the case of the T500 (which takes the data from the folder for the T400), the maximum count for the CPU is set to two. I changed the count to 4, generated the ROM again, flashed it –> You got quadcore. Because the current Libreboot version doesn’t support screens larger than 1280x800 with the T500, I had to extract the original VGA-BIOS for the Intel graphics from the original Lenovo BIOS and integrate it instead of the “native VGA init” into the ROM. -
The Intel Management Engine: an Attack on Computer Users' Freedom by Denis Gnutoo Carikli
A statement by FSF President Richard Stallman on the Intel Management Engine (ME): "Meltdown and Spectre are errors. Grave errors, to be sure, but not evidently malicious. Everyone makes mistakes. Intel has done far worse with its CPUs than make a mistake. It has built in an intentional back door called the Management Engine. Important as these bugs are, don©t let Intel©s mistakes distract you from Intel©s deliberate attack!" The Intel Management Engine: an attack on computer users© freedom By Denis GNUtoo Carikli With security issues like the Spectre and Meltdown vulnerabilities (https://www.cnet.com/news/meltdown-spectre-intel-ceo-no-recall-chip-processor/) discovered in Intel chips in early 2018, it became more important than ever to talk about the necessity of software freedom in these deeply embedded technologies. Serious as though these bugs may be, we cannot let them distract us from the broader issues: Intel considers the Intel Management Engine a feature, while it©s nothing more than a threat to user freedom. Thanks to Denis GNUtoo Carikli, we have a new basis for that conversation in this article. The Intel Management Engine is a tool that ships with Intel chipsets, purportedly to ease the job of system administrators. But in reality, it is another restriction on user freedoms, imposed by a company, and used to control your computing. Carikli offers a moderately technical explanation of what©s happening with Management Engine, the ways in which it restricts rather than empowers users, and how it violates the four freedoms of free software. Carikli may be best known for his work on the Replicant project (https://www.replicant.us/), which he co-founded with Aaron Williamson, Bradley Kuhn, and Grazlano Sorbaioli. -
1 Bilder Bearbeiten
1 Bilder bearbeiten Im Internet finden Sie viele gute Tutorials für die Bildbearbeitung mit Photoshop oder Lightroom, aber mittlerweile sind viele Anwender auf der Suche nach Alternativen. In diesem Skript gehe ich deshalb einen etwas anderen Weg und zeige Ihnen die Gemeinsamkeiten aber auch die Unterschiede unterschiedlicher Software-Produkte. Diese Veröffentlichung wurde nicht von Software-Herstellern gesponsert. Ich habe die Programme nach freiem Ermessen ausgewählt und die kostenlosen Testversionen 30 Tage lang parallel genutzt. Mein Fazit: Im Amateurbereich kann man wunderbar ohne Adobe-Produkte auskommen. Zunächst erhalten Sie einen kurzen Überblick über die grundlegenden Bearbeitungskonzepte. Bei den Anleitungen für die wichtigsten Bearbeitungsschritte verwende ich ganz bewusst Screenshots aus verschiedenen Programmen. Es mag anfangs verwirrend erscheinen, wenn Sie nicht jeden Schritt sofort 1:1 nachmachen können, aber Ihr Verständnis für das Prinzip der Bildbearbeitung wird sich schärfen. Dadurch wird ein Wechsel zu einem anderen Software-Anbieter einfacher. Wenn Sie meine Arbeit unterstützen wollen, freue ich mich über eine Spende auf meinen Paypal-Account.

Libreboot – Free Boot Firmware Libreboot Is a Free Boot Firmware for Use on Computers Certified "Respects Your Freedom"
LibreBoot – Free Boot Firmware LibreBoot is a free boot firmware for use on computers certified "Respects Your Freedom". Most x86 computers are designed to run Windows and come with a non-free BIOS or UEFI firmware that often includes some Malware. Windows itself is malware, and Windows licences are often stored in the BIOS on OEM PCs. For the sake of our freedom we replace Windows with a free distribution of GNU/Linux such as Trisquel (an Ubuntu derivative). But we also have to replace the non-free software that initializes the Hardware with free software. Most hardware vendors do not document how to install a different BIOS, and make it hard to install a different one. But there is coreboot, a free BIOS that can run on some computers. Coreboot contains binary blobs, but some systems can stable run without any blobs. LibreBoot also contains documentation how to install a released version of the coreboot firmware on supported hardware such as some older Thinkpads, and scripts to build the firmware from source, for all supported models. Because newer systems are unable to boot without those blobs, there is no support for newer x86 based computers. For Intel based hardware one challenge is the Management Engine (ME), which is designed for remote out of band management. The firmware for the ME is proprietary and it is impossible to run a free replacement, because it is signed using a secret key. However it is possible to remove the ME firmware on some systems so that it is possible to use them in freedom.
