What's on the waltuh user's mind?

from Misa

In physics, we basically do measurement on all things that can measured. We see a phenomenon or an object, we observe it, take a measurement, and make a mathematical model for describe and predict the behavior of those things.

Since ancient times, Human love to compare things. Imagine if we want to take a free pizza from a party, we would try to see which one is bigger or smaller piece, and of course we will take a bigger piece, right? but how do we know it is bigger that the other piece? simple, just compare it with other piece and you can tell by just looking at it. hey it is a bigger pizza.

Then, there is a question, if something is big, how big is it? If something is long, how long is it compared to another one? Which one is actually bigger? We cannot just say “big” or “small” without knowing how much, right? So we need a way to compare a quantity with another quantity of the same kind. From there, math number is introduced to define and express that quantity clearly.

lets take an example, there is a book and there are identical pens. how we can define how long that book is? we can put pens in row along book and we can tell

“Hey, the book is two pens long”. The length of the book, which is what we measure, is called a quantity. The pen is the object we use as a comparison, which we call a unit, and 2 is the measurement value. With this, we know the length of the book equals the length of 2 pens.

That is measurement. Measurement is the process of comparing a object quantity with another object as a unit. We only can do measurement with comparing quantity with same quantity. length book with length pen, weight with weight, and much more.

The Systeme International (SI) of Units

Imagine we take a measurement like in the example before. Lets say our friend measures the same book using his own pen as a unit of comparison. There is a problem here are the length of his pen might be different from ours, right? If that happens, the measurement value can change. The book might be measured as 3 pens long simply because his pen is smaller. This can lead to confusion.

Now, let’s say another friend measures the same book, but instead of using a pen, he uses a marker, which is a totally different unit. He might find that the length of the book is one and a half markers, while we got a result of 2 pens. This means we can try to convert our unit (length of pen) into his unit (length of marker), which sounds great. However, there is a problem, the conversion process can lead to inaccuracy.

This problem actually happened in the real world. Since ancient times, humans traded using different units from different cultures and regions, which made conversion and price determination difficult. The inconsistency of units often led to fraud and unfairness in trade. This also happened in Ancien Régime, where until 1795, France used many different systems of measurement without a unified standard. There was even widespread abuse of measurement standards for taxation and trade.

The solution to this problem was the creation of a standardized and universal system called the metric system. Thanks to the French Revolution, this system was introduced and later became the foundation of the system are used today. Not go too deep into the history here.

The International System of Units (SI), which consists of 7 base units and its quantity that are widely used by many countries around the world

Quantity Unit Name Symbol Dimension
Length meter m [L]
Mass kilogram kg [M]
Time second s [T]
Electric Current ampere A [I]
Temperature kelvin K [Θ]
Amount of Substance mole mol [N]
Luminous Intensity candela cd [J]

Each unit has its own definition and history. For example, for mass, it is used a physical prototype made of a platinum–iridium cylinder called the kilogram. One kilogram was defined as the mass of that cylinder. This prototype was copied and distributed to many countries as the international standard of mass.

Of course, each definition has been updated over time as technology advances. The more of history of these developments on the official website of the International Bureau of Weights and Measures, the international organization responsible for maintaining these standards

The Paradox of Ownership in the Digital Age:  How DMCA and DRM Limit Access and Undermine Preservation Efforts

 The digital age has ushered in a revolution in how we access and interact with information and culture. E-books, streaming services, and online libraries offer a seemingly boundless collection of knowledge and creative works at our fingertips. However, the concept of ownership in this new landscape remains shrouded in ambiguity. This essay explores how the Digital Millennium Copyright Act (DMCA) and Digital Rights Management (DRM) technologies, intended to protect copyright, create a system where consumers have limited control over their digital purchases. These limitations hinder fair use, restrict access for institutions like libraries and archives, and ultimately raise fundamental questions about true ownership in the digital age.

 Librarians and archivists stand as the guardians of cultural heritage, ensuring future generations have access to the knowledge and creative output of the past. However, the DMCA throws a wrench into their efforts. The act restricts activities like copying and sharing for educational purposes, which are crucial for libraries fulfilling their mission of disseminating information and fostering creativity. As highlighted by McDermott (2012), “complex copyright laws and a misunderstanding of fair use threaten libraries' ability to fulfill their mission of providing information access and fostering creativity”. Librarians often rely on fair use to share excerpts of copyrighted works for educational purposes, create digital copies for long-term preservation, or offer interlibrary loan services. The DMCA's restrictions on these activities create a chilling effect, hindering innovation and jeopardizing the long-term accessibility of knowledge.

 Imagine a scenario where a library owns a physical copy of a book out of print but still protected by copyright. Under the DMCA, the library may be unable to scan and offer a digital copy, even though this could significantly increase accessibility for patrons. This situation exemplifies the tension between copyright protection and the public's right to access information. Furthermore, the DMCA's limitations can restrict libraries from archiving digital materials altogether. A library may be hesitant to acquire e-books due to concerns about the long-term accessibility of the content, potentially impacting user access to valuable resources.

 The DMCA's impact extends beyond access limitations. The act fosters a culture of fear and uncertainty surrounding fair use. Libraries may be reluctant to engage in activities deemed potentially infringing due to the threat of costly litigation; hindering innovation and libraries' ability to effectively serve their communities in this digital age.

 The limitations imposed by the DMCA are further compounded by Digital Rights Management (DRM) technologies. DRM software encrypts content and restricts how users can access and utilize their digital purchases. While DRM serves the purpose of protecting copyrighted material from unauthorized copying and distribution, it also undermines the very notion of ownership in the digital sphere. When consumers purchase an e-book or song, they are essentially buying a license to access the work under certain conditions, not the work itself.

 Scharf (2010) aptly argues that DRM “prioritizes control over user rights”. This translates to limited user control over digital purchases. Imagine purchasing a digital book that you cannot lend to a friend or critically analyze online due to DRM restrictions. This scenario exemplifies how the current system prioritizes control by copyright holders over user rights. Furthermore, the ever-evolving nature of DRM software raises concerns about its long-term compatibility. The potential obsolescence of DRM could render previously purchased content inaccessible in the future, effectively negating any sense of ownership.

 Scharf (2010) further emphasizes the complex relationship between fair use and DRM. “Any attempt to encapsulate fair use provisions within DRM would have drawbacks for both right holders and users...” (p. 182). This quote highlights the inherent tension that exists between user rights and copyright holder control. Striking a balance between the two will be critical in moving forward.

 The limitations of DMCA and DRM extend beyond immediate user experience and have a profound impact on long-term preservation efforts. Libraries and archives face significant challenges in preserving digital content due to these restrictions. As Gasaway (2007) points out, “current limitations on copying and distribution don't translate well to digital media”.

 Unlike physical books, digital files can become inaccessible over time due to changes in file formats or software incompatibility. This presents a significant hurdle for long-term preservation. The focus on “preservation-only” exceptions with restricted access, as discussed in the article by Gasaway (2007), creates a paradox. Restricted access undermines the core purpose of preservation, which is to ensure future generations can access the information. One quote from the article emphasizes this concern: “One question is whether any user should have access to preservation only-copies. In fact, one could argue that the copy is no longer for preservation only if access is being granted to users” (Gasaway, 2007). This quote confirms the concern that restricted access to preserved works challenges the true purpose of preservation, which is to ensure future access. Additionally, the ever-evolving nature of digital formats and technology poses a challenge for long-term preservation.

 While the limitations of current copyright law and DRM pose significant challenges, emerging technologies like blockchain offer a potential solution for securing ownership of digital assets. Blockchain technology utilizes a distributed ledger system, where data is recorded across a network of computers. This creates an immutable record of ownership that is transparent and tamper-proof. Bodó et al. (2018) discusses the potential of blockchain for copyright protection, arguing that “Distributed ledgers are a general-purpose technology, meaning that they are freely configurable to any and every application. In theory, this makes it relatively easy to correspond the core building blocks of blockchain technology to fundamental concepts in copyright law.” (p.314). This further exemplifies how blockchain technology could potentially be a powerful tool for enforcing intellectual property rights through distributed ledgers.

 In theory, blockchain could be used to track ownership of digital content, ensuring creators receive appropriate compensation for their work. Additionally, blockchain could potentially facilitate secure access control for libraries and archives, allowing them to preserve digital materials while ensuring copyright compliance. However, it is important to acknowledge the limitations of blockchain technology in the context of digital preservation.

 Firstly, blockchain itself cannot store copious amounts of data efficiently. While ownership records could be stored on the blockchain, the actual content would likely need to be stored elsewhere. This raises questions about long-term accessibility and potential compatibility issues between storage solutions and future technologies. Secondly, integrating existing copyright laws with blockchain technology presents a complex challenge.

 Despite these limitations, blockchain offers a promising avenue for exploring new models of digital ownership and preservation. As Bodó et al. (2018) concludes, “ Still, should blockchain technology reach its market potential, it may have significant—perhaps transformative—impact on copyright in the digital environment. ” (p. 336). Collaboration between stakeholders – including content creators, copyright holders, technology companies, and libraries – will be crucial in determining how best to leverage blockchain for a more balanced digital ecosystem.

 The issue of digital ownership becomes even more complex when considering piracy. While piracy undoubtedly has negative consequences, the article by Kim et al. (2018) introduces a thought-provoking concept: the “invisible hand” of piracy. The authors argue that “When information goods are sold to consumers via a retailer, in certain situations, a moderate level of piracy seems to have a surprising positive impact on the profits of the manufacturer and the retailer while, at the same time, enhancing consumer welfare.” (Kim et al., 2018, pp. 1117). They explain how piracy can act as a “shadow competitor,” forcing manufacturers and retailers to lower prices or improve accessibility, potentially leading to a more efficient supply chain (Kim et al., 2018). This challenges the current legal framework and traditional views on ownership of digital goods. The concept of “owning” digital media becomes blurry when copying is near-effortless. Piracy can be seen as a symptom of a broken market, where consumers resort to piracy due to limited access or inflated costs. Perhaps a more nuanced approach to piracy is needed, considering the potential benefits and drawbacks in specific situations.

 In conclusion, the DMCA and DRM, while intended to protect copyright, create a system that undermines the concept of true ownership in the digital age. Consumers have limited control over their purchases, fair use is restricted, and long-term preservation of digital materials is hindered. Librarians and archivists, who play a crucial role in safeguarding cultural heritage, are particularly impacted by these limitations.

 Moving forward, a more balanced approach is necessary, one that respects copyright while ensuring fair use rights, promoting open access, and facilitating long-term preservation of our digital heritage. This could involve a few avenues:  • Revising DMCA exemptions for libraries and archives: Expanding exemptions to allow libraries to create digital copies for preservation purposes and offer interlibrary loan services for digital materials.

 • Exploring alternative preservation strategies: Investigating the potential of blockchain technology for secure ownership records while exploring complementary strategies for content preservation outside the blockchain ecosystem.

 • Encouraging collaboration between content creators, copyright holders, technology companies, and user groups to develop new models that prioritize both ownership and accessibility. This could involve exploring innovative licensing models that offer more user control and exploring new revenue streams for content creators in the digital age.

 • Re-evaluating the role of piracy: Considering the potential benefits and drawbacks of piracy in specific contexts and exploring strategies to address the underlying issues that lead to piracy, such as limited access or high costs.

By addressing these challenges, we can move towards a digital ecosystem that fosters creativity, ensures long-term access to information, and respects the rights of both creators and consumers. A system that strikes a balance between copyright protection and fair use is essential for a healthy digital environment where knowledge and culture can continue to thrive.

Some additional considerations we can take with us moving forward:  • Educating users about copyright law, fair use rights, and responsible digital citizenship can help foster a more balanced environment. Libraries and educational institutions can play a crucial role in these efforts.

 • Developing open access models that will facilitate open access initiatives that ensure the public has access to scholarly research and cultural heritage materials helping to democratize access to knowledge and encourage innovation.

 • Investing in robust and secure digital storage solutions for long-term preservation of digital materials. Collaboration between government agencies, libraries, and technology companies will be key in achieving these goals.

 Ultimately, the question of ownership in the digital age is a complex one with no easy answers. However, by fostering dialogue, exploring innovative solutions, and prioritizing both access and creator rights, we can create a more equitable and sustainable digital future.

 Capitalists: ...“You will own nothing and you will be happy.”  Everyone else: ...“Stand up me hearties, yo ho!”

Step 9. Enter TTY with CTRL+ALT+F3, enter username, password, sudo nano /etc/default/grub

(Tip: generally you may select x11 environment in the bottom left corner of the login screen if you want a graphical interface/ get stuck)

Step 10. Add nvidia_drm.modeset=1 as a boot option. This is achieved by appending it within the file /etc/default/grub to GRUBCMDLINELINUX_DEFAULT=“” without deleting other parameters.


Example of modified grub file:

# If you change this file or any /etc/default/grub.d/*.cfg file,
# run 'update-grub' afterwards to update /boot/grub/grub.cfg.
# For full documentation of the options in these files, see:
#   info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`( . /etc/os-release && echo ${NAME} )`
GRUB_CMDLINE_LINUX_DEFAULT="nvidia_drm.modeset=1 nvidia-drm.fbdev=1 quiet"
GRUB_CMDLINE_LINUX=""

# If your computer has multiple operating systems installed, then you
# probably want to run os-prober. However, if your computer is a host
# for guest OSes installed via LVM or raw disk devices, running
# os-prober can cause damage to those guest OSes as it mounts
# filesystems to look for things.
#GRUB_DISABLE_OS_PROBER=false

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE/GOP/UGA
# you can see them in real GRUB with the command `videoinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Step 11. within home/username create the hidden directory .nvtmp

Step 12. set module options for the nvidia module variable at /etc/modprobe.d/nvidia-options.conf uncomment options nvidia-current NVreg_PreserveVideoMemoryAllocations=1 and add NVreg_TemporaryFilePath=~/.nvtmp to the same line

sudo nano /etc/modprobe.d/nvidia-options.conf


Example of modified nvidia-options.conf file:

#options nvidia-current NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660

# To grant performance counter access to unprivileged users, uncomment the following line:
#options nvidia-current NVreg_RestrictProfilingToAdminUsers=0

# Uncomment to enable this power management feature:
options nvidia-current NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=~/.nvtmp

# Uncomment to enable this power management feature:
#options nvidia-current NVreg_EnableS0ixPowerManagement=1

Step 13. add your modules to the initramfs by editing /etc/initramfs-tools/modules and adding nvidia, nvidiadrm, nvidiauvm, and nvidia_modeset to MODULES.

sudo nano /etc/initramfs-tools/modules add MODULES="crc32c nvidia nvidia_drm nvidia_uvm nvidia_modeset"


Example of modified nvidia-options.conf file:

# List of modules that you want to include in your initramfs.
# They will be loaded at boot time in the order below.
#
# Syntax:  module_name [args ...]
#
# You must run update-initramfs(8) to effect this change.
#
# Examples:
#
# raid1
# sd_mod
crc32c
nvidia
nvidia_drm
nvidia_uvm
nvidia_modeset

Step 14. generate initramfs to add the changes you have made.

Di MacOs Tahoe 26.3, GUI Forticlient VPN tidak bisa jalan dengan benar. Mungkin bug atau mungkin juga Forticlient terlalu tolol sehingga membuat aplikasi berjalan sangat lambat atau malah tidak bisa dipakai sama sekali.

Ane sudah reinstall berkali – kali namun tetap saja tidak bisa jalan dengan benar. Versi Forticlient yang ane pakai adalah legacy 6.0 yang harusnya aman dan lancar untuk dipakai. Apakah karena Tahoe 26.3? bisa jadi, oleh karena itu ane coba install versi terkini namun untuk bisa unduh si Fortinet minta data KYC. Bang*t ane ga mau share data pribadi dengan mereka.

Untungnya ada OpenFortiVPN yang ringan dan bisa jalan lancar dari terminal, ane install dari HomeBrew. File Readme.txt sudah sangat jelas dan semua happy ending dalam 3 menit kemudian.
