Zelda 64: Recompiled for PC - Majora's Mask

Zelda 64: Recompiled is a project that uses N64: Recompiled to statically recompile Majora's Mask (and soon Ocarina of Time) into a native port with many new features and enhancements. This project uses RT64 as the rendering engine to provide some of these enhancements.

Play Majora's Mask natively on PC! Download here for Windows or Linux:

Note: Project does not include game assets. Original game is required to play.

Features:

Plug and Play

Simply provide your copy of the North American version of the game in the main menu and start playing! This project will automatically load assets from the provided copy, so there is no need to go through a separate extraction step or build the game yourself. Other versions of the game may be supported in the future.

Fully Intact N64 Effects

A lot of care was put into RT64 to make sure all graphical effects were rendered exactly as they did originally on the N64. No workarounds or "hacks" were made to replicate these effects, with the only modifications to them being made for enhancement purposes such as widescreen support. This includes framebuffer effects like the grayscale cutscenes and the Deku bubble projectile, depth effects like the lens of truth, decals such as shadows or impact textures, accurate lighting, shading effects like the fire arrows and bomb explosions, and various textures that are often rendered incorrectly.

Easy-to-Use Menus

Gameplay settings, graphics settings, input mappings, and audio settings can all be configured with the in-game config menu. The menus can all be used with mouse, controller, or keyboard for maximum convenience.

High Framerate Support

Play at any framerate you want thanks to functionality provided by RT64! Game objects and terrain, texture scrolling, screen effects, and most HUD elements are all rendered at high framerates. By default, this project is configured to run at your monitor's refresh rate. You can also play at the original framerate of the game if you prefer. Changing framerate has no effect on gameplay.

Note: External framerate limiters (such as the NVIDIA Control Panel) are known to potentially cause problems, so if you notice any stuttering then turn them off and use the manual framerate slider in the in-game graphics menu instead.

Widescreen and Ultrawide Support

Any aspect ratio is supported, with most effects modded to work correctly in widescreen. The HUD can also be positioned at 16:9 when using ultrawide aspect ratios if preferred.

Note: Some animation quirks can be seen at the edges of the screen in certain cutscenes when using very wide aspect ratios.

Gyro Aim

When playing with a supported controller, first-person items such as the bow can be aimed with your controller's gyro sensor. This includes (but is not limited to) controllers such as the Dualshock 4, Dualsense, Switch Pro, and most third party Switch controllers (such as the 8BitDo Pro 2 in Switch mode).

Note: Gamepad mappers such as BetterJoy or DS4Windows may intercept gyro data and prevent the game from receiving it. Most controllers are natively supported, so turning gamepad mappers off is recommended if you want to use gyro.

Autosaving

Never worry about losing progress if your power goes out thanks to autosaving! The autosave system is designed to respect Majora's Mask's original save system and maintain the intention of owl saves by triggering automatically and replacing the previous autosave or owl save. However, if you'd still rather play with the untouched save system, simply turn off autosaving in the ingame menu.

Low Input Lag

This project has been optimized to have as little input lag as possible, making the game feel more responsive than ever!

Instant Load Times

Saving and loading files, going from place to place, and pausing all happen in the blink of an eye thanks to the game running natively on modern hardware.

Linux and Steam Deck Support

A Linux binary is available for playing on most up-to-date distros, including on the Steam Deck.

To play on Steam Deck, extract the Linux build onto your deck. Then, in desktop mode, right click the Zelda64Recompiled executable file and select "Add to Steam" as shown. From there, you can return to Gaming mode and configure the controls as needed. See the Steam Deck gyro aim FAQ section for more detailed instructions.

System Requirements:

A GPU supporting Direct3D 12.0 (Shader Model 6) or Vulkan 1.2 is required to run this project (GeForce GT 630, Radeon HD 7750, or Intel HD 510 (Skylake) and newer).

A CPU supporting the AVX instruction set is also required (Intel Core 2000 series or AMD Bulldozer and newer).

Planned Features:

Dual analog control scheme (with analog camera)

Configurable deadzone and analog stick sensitivity

Ocarina of Time support

Mod support and Randomizer

Texture Packs

Model Replacements

Ray Tracing (via RT64)

Back at it again at the [DATA EXPUNGED]

Listening: Vienna Teng, who I encountered in a fancam for industrial society set to Landsailor someone posted on here. Here it is:

Landsailor is good, Hymn to Breaking Strain vibes but from a more civilian perspective, it also has some great names for shit, my favourite being "lawbreaker" for heat pumps. Absolutely incredible.

Reading: Halfway through Fugitive Telemetry, I forgot I had it after I finished Network Effect and anyway, Network Effect was good but kinda too long to spend with Murderbot, the short story format definitely fits it better. I do like how it opens with a Murder(bot) Mystery.

Watching: Watched Scott Pilgrim vs. The World for the first time. It's fun to watch something that is so very of its time. A lot like Clerks in that I watched it way later but I can imagine that had my friends and I seen it back in high school we'd all have been insufferably quoting it at each other the way we did Pirates of the Caribbean. Being vegan just makes you better than other people.

The material is. Fine, I knew it was a Manic Pixie Dreamgirl-focussed movie but I had somehow not realized it had the whole evil exes thing. The parts are greater than the whole.

Making: Marathon cooking session for my dad's birthday, preparing a large set of meals with the added bonus of not having electricity for two hours in the middle of the day. Turned out fine. Ovens are great for preparing large quantities of food quickly, you can do a lot of prep up front and the oven is pretty predictable.

Playing: Started but have not finished An Airport for Aliens Currently Run By Dogs, a comedy fetch quest game by Xalavier Nelson Jr. et al, which is about maintaining your long distance relationship with your fiance while being the last two humans in the universe by meeting up in various airports (for aliens (currently run by dogs)).

The basic game loop is that you have A Place you need to get to to meet your fiance or a specific dog, and you can do that by getting a ticket and finding your way to the appropriate terminal. But the airport is entirely written in a made up substitution cipher so until you learn that you're trying to get around from context clues in increasingly bizarre airports. You often have to get Things for different dogs to get them to help you and eventually get your flight, so you have to figure out the right chain of stores to go to to get your flight on time.

It's fun, it's not that long as far as I'm aware, and it is a nice little thing to have to do. I've been playing it in the mornings before work pretty often.

Tools and Equipment: Slowly setting up Linux on my new laptop, as previously mentioned AMD hasn't put out sensor fusion hub drivers for these Renoir CPU's so while I am pursuing that, I have to have some way to do tablet things in the meantime. Enter lisgd(1).

lisgd(1) is a gesture recognition daemon that works with touchscreens. You can configure (through a config.def.h or through command line flags) a set of gestures and commands for them to execute. I've now set up gestures to control volume and screen brightness as well as to enable and disable the keyboard and rotate the screen for tablet mode stuff. Between that you can replicate all the things the sensor fusion hub is meant to be doing.

There are other ways to do gesture recognition but this one has good tuning options and is pretty platform agnostic. You can do things like very carefully adjust how long a gesture has to be to be recognized or what deviation from the ideal angle will still be picked up.

I'll probably end up writing or finding a little panel utility that will make brightness and volume control simpler, maybe even include the rotation settings there too, but for now this works well enough. That panel will still get triggered by a gesture, so lisgd(1) is going to be load bearing.

[remyousa]

I have been in touch with a close friend of mine who works in rather high security data management, whose identity and specific job title they would prefer not to be disclosed, but this is their advice on best practices for a redundant archive system. Per their words: "External hard drives are good, easy to budget for, can be encrypted, and are effectively air-gapped w.r.t. security (they're only vulnerable when actually connected, which you don't necessarily need most of the time). They're not the most reliable medium though, and you run the risk of losing everything due to mechanical failure if they're in regular use or travel.

The completely other end of the spectrum is something like Amazon S3 - it can be encrypted, but is effectively always-connected, so you have to do all the security yourself (which can be a bit of a burden if you're not really technically savvy - honestly, I'm not savvy enough to understand all the ins-and-outs of that one). It's also a subscription service, so you run the risk of losing everything if you don't/can't pay your bill (though it's not expensive, per se, it's still an imperfectly predictable cost and will tend to be more than the cost of buying a hard drive of equivalent size after about a year).

What I've taken to doing, with my own data (which I don't expect to be raided or whatnot, but using my knowledge of archives to drive my own backup policy), is the following:

Keep one copy as the primary archive. For me, this is on my desktop, but could easily be a laptop, external drive (if that's your primary copy), or whatever.

Keep a second copy, that you replicate from the primary regularly, as a backup. For me, this is a linux server that I keep in my basement. It's basically good for "Ooops, I deleted that thing and want it back" or easy sharing from one computer to another. You can set this one up as your "share" space for others to access if you want, or it could be your "whenever the external drive comes back to me, I make a second copy" that you keep on-hand.

Keep a third copy, that you keep off-site. For me, this is an external drive that I keep in my office at work. I replicate from my backup copy to the external drive about 2-3 times a year. If the house burns down, I'll still have (a maybe older) copy of all my data. I wouldn't recommend burying this one in the woods or anything, but something where you've got a synched copy physically separated is key.

If you're doing this only with external drives, each of these would be separate drives:

1 for you to have on-hand as the "full" archive of what you're trying to save.

1 that gets shipped around, and may get dinged up, but is the primary "share" archive.

1 that your most trusted person has at their house, your studio/office, etc.

If you're doing this with servers, you might have something like:

Your laptop where you keep everything organized

A web site, server, AWS S3 bucket, or whatever for folks to access

An external drive where you back stuff up and keep wherever makes sense.

SSDs travel better, but degrade each time they're written to. HDDs are more reliable long-term, but tend to have mechanical failures if they get bounced around. If I were setting this up using only drives, I would make the "share" drive SSD and expect to replace it more often, but the 3rd copy I would make an HDD.

A good rule of thumb is: 3 copies 2 media types 1 copy off-site."

If you haven’t started already, start archiving/downloading everything. Save it to an external hard drive if you’re able. Collecting physical media is also a good idea, if you’re able.

Download your own/your favorite fanfics. Save as much as you can from online sources/digital libraries. Recipes, tutorials, history, LGBTQ media, etc. It has been claimed, though I can’t find the exact source if true, that some materials about the Revolutionary War were deleted from the Library of Congress.

It’s always better to be safe than sorry and save and preserve what you can. Remember that cloud storage also is not always reliable!

Library of Congress - millions of books, films and video, audio recordings, photographs, newspapers, maps, manuscripts.

Internet Archive - millions of free texts, movies, software, music, websites, and more. Has been taken offline multiple times because of cyber attacks last month, it has recently started archiving again.

Anna's Archive - 'largest truly open library in human history.’

Queer Liberation Library - queer literature and resources. Does require applying for a library membership to browse and borrow from their collection.

List of art resources - list of art resources complied on tumblr back in 2019. Not sure if all links are still operational now, but the few I clicked on seemed to work.

Alexis Amber - TikToker who is an archivist who's whole page is about archiving. She has a database extensively recording the events of Hurricane Katrina.

I'll be adding more to this list, if anyone else wants to add anything feel free!

How to Implement Proxmox VM Backups with NAKIVO Backup & Replication: A Comprehensive Guide

Backing up virtual machines (VMs) is a must for businesses that depend on reliable data access and uninterrupted operations. Proxmox, a popular virtualization platform, offers flexibility for running VMs, but without a strong backup plan, even the most robust virtual environments can fall short in an emergency. That’s where NAKIVO Backup & Replication comes into play, making the backup and recovery process simpler and more secure.

In this guide, we’ll walk through how to set up backups for Proxmox VMs using NAKIVO Backup & Replication in a clear, step-by-step way. This tutorial is for anyone from small business owners to IT teams looking to establish reliable and automatic backups that protect their data without complicating their workflow.

Why NAKIVO Backup & Replication is a Great Fit for Proxmox Users

NAKIVO Backup & Replication is highly rated by companies and IT professionals for good reason—it’s both powerful and user-friendly, making it an ideal choice for protecting Proxmox VMs. Here are some key benefits of using NAKIVO with Proxmox:

Speed and Efficiency: NAKIVO’s backup process is fast and effective, allowing you to keep your systems protected with minimal downtime.

Budget-Friendly: It offers flexible pricing and smart data-saving features, like incremental backups, which help keep storage and operational costs down.

Flexible Backup Options: You can tailor your backup schedule and choose where to store backups, from local drives to network storage, giving you options as your business needs grow.

Ransomware Protection: With built-in encryption and advanced access controls, NAKIVO safeguards your backups against threats like ransomware.

With these benefits in mind, let’s dive into the steps to set up Proxmox VM backups using NAKIVO.

Step 1: Get Your Proxmox Environment Ready

Before we jump into the setup, it’s essential to make sure your Proxmox environment is properly configured. Here’s a quick checklist:

Update Proxmox: Always ensure you’re running the latest version of Proxmox, as updates often include important security and compatibility improvements.

Install Necessary Modules: Confirm that modules like QEMU and LVM are installed. These modules are important for managing VMs and are essential for smooth backup operations.

Choose Your Storage: Decide where your backup data will go. For companies with multiple VMs, a network-attached storage (NAS) solution or external drive will make it easier to manage large volumes of backup data.

Step 2: Install NAKIVO Backup & Replication

Once your Proxmox setup is ready, it’s time to install NAKIVO Backup & Replication. This software works on multiple platforms, so choose the one that best fits your system.

Download the Installer: Visit the NAKIVO website and download the installer. NAKIVO provides options for different environments, like Linux, Windows, or a NAS device.

Run the Installation: Once you’ve downloaded the installer, follow the instructions specific to your operating system. For Linux users, this might mean running a few terminal commands; on Windows, it’s usually a simple setup wizard.

Access the NAKIVO Dashboard: After installation, open a web browser and log into the NAKIVO dashboard using the default login credentials provided. The dashboard is where you’ll set up and monitor backups.

Step 3: Connect Proxmox to NAKIVO

With NAKIVO installed, the next step is to link it to your Proxmox environment so it can locate and interact with your VMs.

Add Proxmox to Inventory: In the NAKIVO dashboard, go to “Inventory” and click on “Add New.”

Select Proxmox as Hypervisor: Choose “Proxmox” from the list of available hypervisors. This selection tells NAKIVO to look for Proxmox servers in the network.

Enter Proxmox Server Credentials: Input the IP address and login credentials for your Proxmox server to enable access.

Verify Connection: NAKIVO should now recognize your Proxmox VMs in the dashboard. If you see them listed, you’re all set to start configuring backup jobs.

Step 4: Set Up Backup Jobs for Your VMs

Now that NAKIVO and Proxmox are connected, it’s time to configure the actual backup jobs that will keep your data safe.

Create a New Backup Job: In the NAKIVO dashboard, click on “Create” and select “New Backup Job.” This is where you’ll define settings for each VM’s backup.

Select VMs to Include: Pick the VMs you want to back up. You can choose individual VMs or entire groups if you want to save time and back up multiple VMs at once.

Define a Backup Schedule: Decide how often you want to run backups. For critical data, daily backups are ideal; less crucial data might be backed up weekly. NAKIVO also offers incremental backups, which only back up changes since the last backup, saving time and storage.

Choose Backup Storage: Select where to store your backups. Options range from local storage to network drives, or even the cloud if that’s an option for your business.

Set Retention Policies: Retention policies help manage storage by automatically deleting older versions of backups. This allows you to keep recent versions without overloading your storage.

Step 5: Explore NAKIVO’s Advanced Features

NAKIVO offers advanced features that help you get more value from your backups:

Ransomware Protection: Encrypt your backups and restrict access to them to prevent data loss in case of a ransomware attack.

Data Compression: NAKIVO’s compression feature reduces backup size, which is especially helpful if you’re working with limited storage.

Automated Reporting: Configure automated reports to keep you updated on backup status, job completion, and any potential issues, so you’re always in the loop.

Step 6: Test and Verify Your Backups

Testing backups might seem like an extra step, but it’s essential to ensure that your data can be restored correctly when needed.

Run a Test Restore: From the NAKIVO dashboard, try restoring a backup to verify it’s complete and functional. This test gives you peace of mind that the data is usable in case of an emergency.

Check for Data Integrity: Make sure all your critical files and data are present and undamaged in the restored backup. Regular testing helps ensure reliability.

Schedule Routine Tests: If you manage a lot of VMs, it’s a good idea to test backups periodically. Quarterly tests or tests after significant system updates keep you prepared for any data recovery scenarios.

Step 7: Monitor and Maintain Your Backup System

After setting up your backup jobs, keeping an eye on backup performance and identifying any issues will help maintain a dependable system.

Set Up Alerts: Configure alerts to notify you of backup issues, like job failures or storage capacity warnings. Alerts can be sent by email or SMS for convenience.

Review Backup Reports Regularly: NAKIVO’s detailed reports let you see how your backups are performing, providing insights into any potential issues or storage usage trends. Regularly reviewing these reports helps keep your backup strategy effective.

Pro Tips for Optimizing Proxmox VM Backups

Here are a few final tips to help you maximize your Proxmox backup strategy:

Use Multiple Backup Locations: Storing backups in multiple locations (e.g., local storage and cloud storage) adds an extra layer of protection against data loss.

Stay Updated: Make sure both Proxmox and NAKIVO Backup & Replication are updated regularly for optimal security and performance.

Tailor Backup Schedules by Priority: Some VMs are more critical than others, so back up essential systems more frequently than less critical ones to save storage and backup time.

Valkey 8.0 On Memorystore Expands Open-Source Performance

Google is excited to launch Valkey 8.0 in preview form on Memorystore today, making Google Cloud the first significant cloud provider to provide Valkey 8.0 as a fully managed service. This strengthens Google Cloud’s dedication to open source, building on the release of Memorystore for Valkey 7.2 in August 2024 and giving you access to the newest and best features from the Valkey open-source community.

Major League Baseball (MLB) and other customers are examples of Google cloud dedication to customer service, as demonstrated by Valkey 8.0 on Memorystore. MLB, the most storied professional sports league, processes enormous volumes of data in real-time to give fans insights and statistics during games using Memorystore.

The release of Valkey 8.0

The open-source community banded together to establish Valkey a fully open-source alternative under the BSD 3-clause license, earlier this year after Redis Inc. altered the license of Redis OSS from the permissive BSD 3-Clause license to a restrictive Source Available License (RSAL). The open-source Valkey 8.0 was made available to the public in a matter of months by the Valkey community, demonstrating the strength of unrestricted innovation and open-source cooperation.

The latest version of the open-source NoSQL in-memory data store, Valkey 8.0, was released today, according to a statement from the Linux Foundation. With major upgrades intended to improve performance, dependability, and observability for all installations, Valkey 8.0 demonstrates quick innovation. By adding new features that elevate Valkey and building on the qualities of its past open source releases, this release strengthens the foundation.

The release’s main highlights are as follows:

Throughput on AWS r7g instances is improved up to 1.2 million requests per second with intelligent multi-core usage and asynchronous I/O threading, more than three times greater than the previous version.

Enhanced cluster scalability with replicated migration states and automated failover for additional shards

Dual-channel RDB and replica backlog streaming for faster replication

Granular visibility into performance and resource utilization is provided by extensive per-slot and per-client metrics, which include pubsub clients, rehash memory, event loop latency, and command-level heavy traffic recording.

Reduced memory overhead by up to 10% with improved key storage.

Valkey 8.0 may be downloaded right now at valkey.io, and those who already have it can update with a few quick keystrokes. Valkey can be installed using pre-made container images or constructed from source.

As a fully Google managed service, Memorystore for Valkey 8.0 offers better performance, increased dependability, and complete compatibility with Redis OSS.

Wth to recently introduced asynchronous I/O capabilities, the Valkey performance benchmarks have improved. By allowing the main thread and I/O threads to run simultaneously, the improved I/O threading system maximizes throughput by minimizing bottlenecks in handling incoming requests and enabling parallel processing of commands and I/O operations. Compared to Memorystore for Redis Cluster, Memorystore for Valkey 8.0 achieves up to a 2x Queries Per Second (QPS) at microsecond latency, enabling applications to handle higher throughput with clusters of same size. Because of this, Valkey 8.0 is an excellent option for real-time, high-throughput applications that need to deliver very rapid user experiences.

Valkey 8.0 has further optimizations in addition to the throughput gain that improve the service’s overall speed:

Set union procedures can be completed more quickly with the SUNION command.

To achieve faster execution speeds, changes have been made to the ZUNIONSTORE and SDIFF commands.

For expired keys, the DEL command prevents redundant deletions.

Responses from CLUSTER SLOTS are cached to improve throughput and lower latency during cluster activities.

Large data batches benefit from increased CRC64 performance, which is essential for RDB snapshot and slot migration scenarios.

Enhancements to key-memory efficiency are another feature of Valkey 8.0 that let you store more data without having to modify your application. Performance has improved and memory overhead has decreased because to the direct embedding of keys into the main dictionary. Furthermore, the main dictionary is divided into slots by the new per-slot dictionary, which reduces memory overhead by an additional 16 bytes per key-value pair without compromising performance.

Meanwhile, a number of Google-developed innovations that were later added to the project have increased the stability of Valkey 8.0 and greatly improved cluster resilience and availability:

Even in the early phases of scaling, automatic failover for empty shards contributes to high availability by facilitating the seamless failover of newly created, slotless shards.

Replicating slot migration states lowers the chance of data unavailability during failover events and allows new replicas to immediately inherit the right state. It also helps ensure that all CLUSTER SETSLOT commands are synchronized across replicas prior to execution on the main.

Furthermore, slot migration state recovery guarantees that, during a failover, the source and destination nodes are immediately updated, preserving precise request routing to the appropriate primary without the need for operator interaction.

These improvements increase the resilience of Valkey 8.0 clusters against failures during slot transfer, providing clients with the assurance that their data will remain accessible even during intricate scaling processes.

Compliant with Redis OSS version 7.2

Similar to Valkey 7.2, Redis OSS 7.2 APIs are fully backwards compatible with Valkey 8.0, facilitating a smooth transition away from Redis. Well-known Redis clients like Jedis, redis-py, node-redis, and go-redis are completely supported, negating the need for application code changes when transferring workloads to Valkey.

Because Valkey combines the flexibility of open-source software with the dependability of managed services, it offers you an ideal mix of control and simplicity when it comes to your Redis OSS workloads.

Start using Valkey 8.0 on Memorystore

Google cloud cordially encourage you to begin using Valkey 8.0 on Memorystore right now so you can see the aforementioned improvements. Memorystore’s Valkey 8.0 offers the performance, stability, and scalability that today’s high-demanding applications require with features like zero-downtime scaling, high availability, and RDB snapshot and AOF logging based persistence.

Begin by setting up a fully managed Valkey Cluster using the gcloud or Google Cloud console, and become a part of the expanding community that is influencing the direction of truly open-source data management.

Something I wanted to add because it seems to be something a lot of people aren't aware of:

No amount of extensions will anonymize you. While most people have different threat levels and don't need to be anonymous online, the fact remains, extensions tend to make your browser MORE fingerprintable. If your goal is to prevent each individual website from collecting as much data as possible, then extensions are a good solution. However, if you don't want entities and networks of entities to be able to track you from one website to another, including cross-website advertising trackers, you need to minimize your extensions as much as possible.

Also, it's typically recommended that you install and use only ONE adblocker. The way adblocker blockers work (like the ones YouTube are currently implementing) is that they inject "fake" invisible ads into your browser and then monitor them to see if they load. If your adblocker blocks this fake ad, then it triggers the anti-adblocker pop-up. If it does not, however, you get to continue browsing, ad-free. By using multiple adblockers, you not only increase the chance that one of them will take the bait, but you also risk them getting their rules intertwined and causing the bait to accidentally be taken when none of them, on their own, would've triggered it. uBlock Origin is typically regarded as the best of the best, so I recommend using it, and it alone.

Also, Privacy Badger is """allegedly""" quite outdated/useless and tends to make your browser more fingerprintable, simply because having an additional extension installed adds more to your fingerprint than Privacy Badger can take away.

If you're worried about your privacy, set Firefox's built-in Cookie Protection to "Strict." It warns you that some sites may break, but Mozilla recently implemented a new "Total Cookie Protection" feature that intelligently predicts and remembers which cookies will break a website and leaves them alone. I've used Firefox on "Custom" privacy settings (so I can make it even more strict than "Strict"), and I've never had a website fail to load because of cookie issues.

Also-also, HTTPS Everywhere is no longer needed. Firefox has that built-in, too. Go to Settings > Privacy & Security > HTTPS-Only Mode, and set it to "Enable HTTPS-Only Mode in all windows." That way you can remove HTTPS Everywhere and make your browser less fingerprintable.

And Finally, while it's not here, Cookie AutoDelete is another popular privacy extensions. However, like HTTPS Everywhere and Privacy Badger, by simply having it installed, you're doing more harm to your browser's fingerprint than you are helping. Firefox has a very similar ability to delete cookies on it's own. Go to Settings > Privacy & Security > Cookies and Site Data, and turn on "Delete cookies and site data when Firefox is closed." This does not replicate Cookie AutoDelete's behavior of deleting cookies when you close tabs. What it does is; it will delete cookies when you hit the "x" button to close Firefox (Windows and Linux) or right click and select "Quit" (macOS). Some people may find this a deal breaker, and that's fair, but for my use case, and plenty of others, deleting cookies only when the browser, itself, is closed works much better, especially if you close your browser every time you're done with it, like I do. It'll allow you to login into places without having to manually sign-in every single time, but if you ever close the browser, then it'll make you manually sign-in, which I feel is a good balance between convenience and security.

hello google chrome refugees

don't use any of these browsers, they're also chrome

Here are my favorite firefox plugins for security/anti-tracking/anti-ad that I recommend you get

please get off chrome google is currently being investigated for being an Illegal Monopoly so get outta there okay love you bye

Responding to this reply by @omuriceandriesling

"Might be a good opportunity to take one of my empty external drives and start saving things. I wonder if there Is there a faster way to do that than just right click->save as thousands of times"

Okay so for some reason this doesn't work on mangadex, but I'm hoping this'll give people some ideas of workarounds, and also work on other sites. Also this is just how I'd do it, tools and tricks that I have used, there are probably faster or better ways. Not an expert, just someone who has made comic files from online images occasionally :)

You will need a Windows desktop/laptop running one of the main three browsers, a willingness to fuck around with data, an app that can read CBZ, and storage space. This is most likely replicable in Mac/Linux but I don't have those so we're doing Windows. Specifically Windows 10 but again, you can figure it out for newer or older versions.

Download an addon called down them all! (available for Firefox, Edge, and Chrome) and 7zip or anything else that can make zips. There is also an addon called download all images which automatically makes zip folders which will save some effort but I found it downloaded wrong things and idk, I didn't like it, but it may be worth fiddling with if you feel like it.

Put the manga site into a scroll down format, so you can get as many pages on the page as possible. Right click and choose the downthemall! option, go to the media tab and select images. Strip out as much of the obvious site furniture as you can (stuff that says "header" and "navigation" etc.). You are hopefully looking at a long string of sequentially named images, but we'll come to that. Don't forget to make a folder and tell it to save there before clicking download.

Right, so you have your images. Type into your start bar "show file extensions", tick the option that comes up, then the little "show settings" next to it. In the panel that comes up untick hide extensions for known file types. If you've got it right you should now see all your files like image.jpg etc.

Go have a look at the images you've downloaded. If you've not already, then set your icon thumbnail size (using right click- view) to big enough to see that all you've got is pages, and also sort by name. Delete anything you don't need. If they love you it'll be numbered like 001, 002 etc. It can have words in there as long as they're all the same, but the leading zeros are important. We're essentially alphabetising this to make it back into a comic, and if you don't have zeros then you'll read page 1, followed by page 10... you see the problem. If you go above 100 pages you'll need 4 leading zeroes. If they don't love you then you can sit there renaming to make it make sense, there are tools out there to help but I've not got any particular recommendations.

Done with that? Cool, this is the magic bit. Zip up your folder, and then you see the .zip at the end? Triple click or choose rename from the right click options, and change that .zip to a .cbz Abracadabra and alakazam you now have a cbz file, which can be read by any good comic reader. I like Perfect Viewer for android, you can change which direction you read from if you need to. On desktop cbz can be read on Calibre which is another very useful program to have, but that's for another post.

Hey just so yall know mangadex is going down bc big companies are cracking down on piracy. Please archive your favorite manga

This is especially devastating for the english showa era community because we have no other option.

VPN encryption protocols

Title: Understanding VPN Encryption Protocols: Safeguarding Your Online Privacy

In the digital age, where cyber threats lurk around every corner of the internet, safeguarding your online privacy has become paramount. Virtual Private Networks (VPNs) offer a solution by encrypting your internet traffic, making it indecipherable to prying eyes. However, not all VPN encryption protocols are created equal. Understanding the different encryption protocols is essential for choosing a VPN service that best meets your security needs.

One of the most common encryption protocols used by VPNs is OpenVPN. Praised for its open-source nature and robust security features, OpenVPN employs OpenSSL library encryption to ensure data confidentiality and integrity. Its flexibility allows it to be implemented across various platforms, including Windows, macOS, Linux, iOS, and Android.

Another widely adopted protocol is Internet Protocol Security (IPsec). IPsec operates at the network layer of the OSI model and utilizes cryptographic algorithms to secure data transmission. It offers strong encryption and authentication mechanisms, making it ideal for securing sensitive information.

Transport Layer Security (TLS) is also utilized by some VPN providers to encrypt data transmitted between your device and the VPN server. Originally designed to secure web communication, TLS has evolved into a versatile protocol used in VPNs to ensure secure connections.

In recent years, WireGuard has gained popularity for its simplicity and efficiency. Built into the Linux kernel, WireGuard boasts faster connection speeds while maintaining robust security through modern cryptographic techniques.

When choosing a VPN service, it's crucial to consider the encryption protocols it supports. Look for providers that offer a variety of protocols, allowing you to select the one that best suits your security and performance requirements. Additionally, ensure that the VPN implements strong encryption algorithms and follows best practices to protect your online privacy effectively. By understanding VPN encryption protocols, you can make informed decisions to safeguard your digital life.

User authentication methods

User authentication methods are crucial for ensuring the security and integrity of online platforms. These methods are designed to verify the identity of users and grant access to confidential information or certain features based on their credentials. There are several common user authentication methods used across various digital platforms:

Password-Based Authentication: This is the most common form of user authentication, where users are required to input a designated password to access their accounts. Passwords should be complex, unique, and regularly updated to enhance security.

Two-Factor Authentication (2FA): 2FA adds an extra layer of security by requiring users to provide a second form of identification along with their password. This could include a verification code sent to their mobile device or a fingerprint scan.

Biometric Authentication: Biometric authentication uses unique physical characteristics such as fingerprints, facial recognition, or iris scans to verify a user's identity. These features are difficult to replicate, enhancing security.

Multi-Factor Authentication (MFA): MFA combines two or more authentication factors such as something the user knows (password), something they have (mobile device), and something they are (fingerprint) to grant access.

Token-Based Authentication: Token-based authentication involves the use of a physical device, like a security key or smart card, which generates a unique token for each login attempt. This method is highly secure and less susceptible to phishing attacks.

It is essential for organizations to implement robust user authentication methods to protect sensitive data and prevent unauthorized access. By choosing the right authentication methods based on the level of security required, businesses can safeguard their digital assets and user information effectively.

Password management policies

In today's digital age, password management policies are crucial for maintaining the security of sensitive information. A password management policy outlines the guidelines and procedures that an organization or individual should follow to create, store, and protect passwords effectively. By implementing a robust password management policy, the risk of unauthorized access to confidential data can be minimized significantly.

One of the key aspects of a password management policy is creating strong passwords. Strong passwords typically include a combination of letters (both uppercase and lowercase), numbers, and special characters. They should be unique for each account and regularly changed to enhance security further. Passwords should never be shared with others and should be stored securely using reputable password management tools.

Furthermore, implementing multi-factor authentication (MFA) as part of the password management policy adds an extra layer of security. MFA requires users to provide two or more forms of identification before gaining access to an account, making it more challenging for unauthorized individuals to breach security.

Regular security training and updates on best practices for password management should also be included in the policy. Employees need to be educated on the importance of strong passwords, how to recognize phishing attempts, and the potential risks of weak password security.

Overall, a well-defined password management policy is essential for safeguarding sensitive information and preventing unauthorized access. By adhering to the guidelines outlined in the policy, organizations and individuals can minimize the risk of security breaches and protect their valuable data effectively.

Data privacy regulations

In an era dominated by digital interactions, data privacy regulations have become paramount in safeguarding individuals' personal information. These regulations serve as a bulwark against the misuse and unauthorized access of sensitive data by governments, corporations, and other entities. The advent of technologies like artificial intelligence and big data analytics has heightened concerns about privacy breaches, making robust regulations essential.

One of the most significant data privacy regulations globally is the General Data Protection Regulation (GDPR), implemented by the European Union (EU) in 2018. GDPR empowers individuals with greater control over their personal data, requiring organizations to obtain explicit consent before collecting and processing such information. It also mandates stringent measures for data protection and imposes hefty fines on non-compliant entities, underscoring the seriousness of data privacy.

Similarly, in the United States, the California Consumer Privacy Act (CCPA) stands as a landmark regulation aimed at fortifying data privacy rights for Californian residents. CCPA grants consumers the right to know what personal information is being collected and to opt-out of its sale, providing them with a higher degree of autonomy over their data.

Furthermore, emerging regulations like the Personal Data Protection Bill in India and the Data Protection Law in Brazil reflect a global trend towards bolstering data privacy frameworks. These regulations acknowledge the evolving landscape of data usage and emphasize the importance of accountability and transparency in data handling practices.

Overall, data privacy regulations are indispensable tools for fostering trust in the digital ecosystem. By upholding individuals' rights to privacy and promoting responsible data management practices, these regulations pave the way for a more secure and equitable digital future.

Trustworthiness of VPN providers

When it comes to selecting a Virtual Private Network (VPN) provider, one of the most crucial factors to consider is trustworthiness. VPN services are designed to offer online privacy, security, and anonymity by routing your internet traffic through an encrypted tunnel. However, not all VPN providers are created equal, and some may not always have your best interests at heart.

To determine the trustworthiness of a VPN provider, there are several key factors to consider. Firstly, check the provider's privacy policy and regulations. Look for a no-logs policy, which means that the provider does not record any of your online activities. This ensures that your data remains private and secure.

Secondly, consider the company's jurisdiction. Opt for VPN providers that are based in privacy-friendly countries with strict data protection laws. This ensures that your data is not vulnerable to government surveillance or data retention laws.

Additionally, look for independent audits or third-party assessments of the VPN provider's security measures. A trustworthy VPN provider will regularly undergo security audits to validate its encryption protocols and security practices.

Lastly, consider the provider's track record and reputation within the industry. Look for reviews from experts and users to gauge the reliability and performance of the VPN service.

By evaluating these factors, you can make an informed decision when selecting a trustworthy VPN provider that prioritizes your online privacy and security. Remember, trust is essential when it comes to safeguarding your personal information online.
