The Windows page file is a file on the hard drive that acts as virtual memory when RAM is full. It stores data from RAM so programs don't crash when RAM is full. While slower than RAM, it's better than not having a page file. Most users should leave the page file settings to Windows' default configuration, but it can help performance to move the page file to a separate drive in some cases. Disabling the page file is not recommended and can cause system instability.

2022 fixed cant read from source file or disk errorZoey Chen
No one wants to suffer from problems with their computer, especially the kind that affect their daily work and life. However, there is no way to avoid computer problems in our daily life, and in this era when computers are vulnerable to intrusion, we can only do everything possible to protect them. Windows users who regularly transfer large files are no stranger to the "cannot read from source file or disk" error message. There are many reasons for this phenomenon. Users of Windows on Microsoft and other platforms report that their Windows cannot read from source files or disks. A large percentage of users report that the "Windows 10 can't read from the source file or disk" error occurs when they try to transfer large files from their hard drive to their computer. One such complaint on the Microsoft community can be seen here:

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Htg explains what is the windows page file and should you disable it

HTG Explains: What is the Windows Page File and Should You Disable It?
How-To Geek
HTG Explains: What is the Windows Page File and Should You Disable It?
Windows uses a page file to store data that can’t be held by your computer’s random-access memory when it fills up. While you
can tweak the page file settings, Windows can manage the page file fine on its own.
The Windows page file is somewhat misunderstood. People see it as the cause of slowdowns because it’s slower to use the page file
than your computer’s RAM, but having a page file is better than not having one.

How The Page File Works
The page file, also known as the swap file, pagefile, or paging file, is a file on your hard drive. It’s located at C:pagefile.sys by
default, but you won’t see it unless you tell Windows Explorer not to hide protected operating system files.
Your computer stores files, programs, and other data you’re using in your RAM (random access memory) because it’s much faster
to read from RAM than it is to read from a hard drive. For example, when you open Firefox, Firefox’s program files are read from
your hard drive and placed into your RAM. The computer uses the copies in RAM rather than repeatedly reading the same files from
your hard drive.
Programs store the data they’re working with here. When you view a web page, the web page is downloaded and stored in your
RAM. When you watch a YouTube video, the video is held in your RAM.

When your RAM becomes full, Windows moves some of the data from your RAM back to your hard drive, placing it in the page file.
This file is a form of virtual memory. While writing this data to your hard disk and reading it back later is much slower than using
RAM, it’s back-up memory – rather than throwing potentially important data away or having programs crash, the data is stored on
your hard drive.
Windows will try to move data you aren’t using to the page file. For example, if you’ve had a program minimized for a long time and
it isn’t doing anything, its data may be moved to RAM. If you maximize the program later and notice that it takes a while to come
back instead of instantly snapping to life, it’s being swapped back in from your page file. You’ll see your computer’s hard disk light
blinking as this happens.

With enough RAM in modern computers, the average user’s computer shouldn’t normally use the page file in normal computer use.
If you do see your hard drive start to grind away and programs start to slow down when you have a large amount open, that’s an
indication that your computer is using the page file – you can speed things up by adding more RAM. You can also try freeing up
memory — for example, by getting rid of useless programs running in the background.
Myth: Disabling the Page File Improves Performance
Some people will tell you that you should disable the page file to speed up your computer. The thinking goes like this: the page file
is slower than RAM, and if you have enough RAM, Windows will use the page file when it should be using RAM, slowing down your
computer.
This isn’t really true. People have tested this theory and found that, while Windows can run without a page file if you have a large
amount of RAM, there’s no performance benefit to disabling the page file.
However, disabling the page file can result in some bad things. If programs start to use up all your available memory, they’ll start
crashing instead of being swapped out of the RAM into your page file. This can also cause problems when running software that

requires a large amount of memory, such as virtual machines. Some programs may even refuse to run.
In summary, there’s no good reason to disable the page file – you’ll get some hard drive space back, but the potential system
instability won’t be worth it.
Managing the Page File
Windows automatically manages the page file’s settings for you. However, if you want to adjust your page file settings, you can do
so from the Advanced System Settings window. Click Start, type Advanced System Settings into the Start menu and press Enter
to open it.
Click the Settings button under performance.
Click over to the Advanced tab and click the Change button in the Virtual memory section.

HTG Explains: What is the Windows Page File and Should You Disable It?
Windows automatically manages your page file settings by default. Most users should leave these settings alone and allow Windows
to make the best decision for you.
However, one tweak that may help in some situations is moving the page file to another drive. If you have two separate hard drives
in your computer, assuming one is the system drive with your programs installed on it and one is a less-used data drive, moving
the page file to the data drive can potentially offer some increased performance when your page file is in-use. Assuming that
Windows will already be using the system drive if it needs to use the page file, this spreads out the hard drive activity instead of

concentrating it on one drive.
Note that this will only help if you actually have two separate hard drives in your computer. If you have one hard drive separated
into multiple partitions, each with their own drive letter, this won’t do anything. Whether it’s partitioned or not, it’s still the same
physical hard drive.
In summary, the page file is an essential part of Windows. Even if it’s rarely used, it’s important to have it available for situations
where programs are using an unusually large amount of memory.
Having a page file won’t slow down your computer – but if your computer is using its page file a lot, you should probably get some
more RAM.
