got all my stuff done for class today. definitely spent a lot of time getting it all finished this weekend, but the upside is that i dont really have anything to worry or crunch about tomorrow

it was a productive learning experience since at work ive been doing a lot of stuff focused on the DB and forms aspect of things, and for this class site i focused more on state/interactivity throughout the page so that im comfier with alpine and the general life cycle of things. makes me aware of various limitations im gonna have to work around, but i do think it should be OK

plan for monday is that if all the migrations and seeders i wrote on friday work as i hope (and they did seem ready to go at that point) then im going to see about making the first bespoke form, cause while the out-of-the-box stuff we have is solid, there's just a whole heck of a lot of information density i need

i do wanna experience a tiny bit with using the out-of-the-box approach, but only to see kinda where it stops working. just too information dense with too many connected models

that latter point is probably also something i should keep in mind before i fully commit to my migrations, but idk. i still feel like ive made the right choice. but im going to keept he option open to humour the more... naive approach if it seems necessary, cause i think it's much more important to have the data be easy to work with than like.t he absolute most pure abstract representation of the stuff

Happy timezones Sky kids!

We have an update on the bug that was causing players to repeat the Daily Light refresh animation and not be able to forge candles. As I’ve stated in previous, less formal messages to you all in Discord, “This was a tricky one.”

What happened?

Without getting into too many technical details, the root condition for the bug was database-related. Specifically, there was an inability of our backend services to write to certain player fields—namely, the ones that record when the Light a player has collected is forged to a corresponding number of Candles.

What we ultimately found was a bug in the configuration of our provider’s database infrastructure, something outside of our control. Our team confirmed this by meticulously analyzing data related to the issue and worked with our provider, who was able to pinpoint a workaround on their end earlier this week as they continue to work towards a permanent fix.

What does this mean for players?

Players should be able to forge candles without any further problems. If you’re still running into this issue, please send us a bug report in the ⁠"report-a-live-bug" channel on the Official Discord.

What about making it right for players?

We are still in the process of analyzing data to verify the extent of this bug’s impact so that we can determine how to best offset the effects for players who were afflicted by it. Once we’ve figured that out, we will notify those players accordingly!

We know that this has been frustrating for the players who were experiencing this bug, and we want to send you all another thank you for bearing with us during this time!

Hi! I juuust found your work, and I like it (namely through that formatting post, but now I'm actually reading through CURSE/KISS/CUTE and, hey! It is cute! Aster's growing on me)!

I'm actually in the process of writing another book—er, webnovel. Something free because I want people to have the chance to actually invest themselves in it—and I wanted to ask! Did you code the site all yourself, or did you use something as a framework? And, to someone who doesn't know much code, what would you reccomend?

Asters are always growing in odd places ...

I coded the whole entire thing myself. I even coded a ton of backend tools that live on my computer for automating tasks like formatting pages and converting images. I did all of this because I’m a freak...? And I wanted to optimize for fast, lightweight page loads with no server-side rendering. (The entire website is static HTML.)

For someone less inclined to hubris than me, depending on your skill level or interest in learning web code I would recommend either:

just using Wordpress (every web host in existance has a big glowing button labeled “install wordpress” for making a wordpress site and there are endless templates for formatting any kind of post you can imagine with no coding required), or

picking a static site generator and using that (for a fast and lightweight website but one that you might have to do a little coding to finish out the way you like it).

Notably, one thing I don’t recommend is using SquareSpace. For one thing, they have an adult content ban on the books; for another, if you ever do want to do something as basic with your website as “upload an HTML page you coded yourself”, you’ll find yourself locked out in the cold, because that’s grown-up stuff and they don’t like you doing that. (Learning this the hard way is the reason I ended up making my new website myself. A nice thing about a static site is that not only do you have complete control, but it’s fully portable, too: just paste the files into whatever web host you like and it’ll work just the same.*)

*except sometimes you gotta configure your .htaccess a bit etc

Frontier systems were impacted by a Microsoft outage, including booking, check-in, access to boarding passes and some flights, the company said

"A backend cluster management workflow deployed a configuration change causing backend access to be blocked between a subset of Azure Storage clusters and compute resources in the Central US region," Redmond explained. "This resulted in the compute resources automatically restarting when connectivity was lost to virtual disks."

chat, am I futureshock ?

occasionally I get people say stuff like this, and I'm glad they like my blog, I'm glad they enjoy the surface-level vibes. nonbinary matrix header, soft retro-vibe colourscheme, posts appearing as shell commands, etc.

but I'm not an aesthetic blog

I'm what happens when an autistic tranny who is A Bit Too Much Computer witnesses the realtime enshittification of everything.

first up, i wanna be clear that i'm not trying to shit on the person who sent me this or discourage people who enjoy these aesthetics (or what they perceive as my personal brand) for enjoying them, or from diving deeper. in fact, i would encourage it - please !! go look into things !! discover !! fuck things up !! fix them !!!

now i wanna talk about aesthetics. i love the design language of a lotta late 80s hardware, vehicles, physical interfaces. i love the design language of a lot that in the 90s, as well as software, early GUI stuff etc. and tbh a lot of that right up until the mid 00s. if we wanna play deeply unserious but whimsical visual signifiers for fun and silly reasons, sure then i'm webcore, i'm hackercore, i'm retrofuture and cyber, i'm cassette futurist, i'm cyberpunk or whatever. i'm cute glittery gifs of windows 95 slate dialog boxes and big standing racks full of das blinkenlights. i'm the cave shadow of a CD Walkman i'm that big chonky 80s red 7-segment alarm clock.

but i'm not just aesthetics. i'm not doing all this purely for the bit. up until a couple years ago i was sacrificing a ton of convenience for my principles. now i'm sacrificing certain specific conveniences and a buncha anti-consumer nonsense for my principles and a shit ton of other, better, conveniences.

this wasn't meant to be a long post, and may well end up influencing some of my cyberpriestess posting when i get my website going, as there's a lotta good jumping-off points here.

let me show y'all how i live. at least some of it.

daily driver ? 11-year-old gaming pc w/ some recent era-appropriate upgrades (well, the gpu is pushing it but like is reasonable someone would've done that upgrade).

this is what i mean. this is pluug2, my daily driver. and she still runs games. and yes i'm using arch rn bc i did a reinstall and for whatever reason the version of the void installer i had was corrupted and arch was the only other diy distro i had laying around. she'll end up running something infinitely more cursed in the future once i get s6 stuff figured out.

i spent like half an hour configuring fastfetch (the backend i'm using for hyfetch) bc the default kinda sucked. that's how this works.

i do dumb shit, i have fun, i live by my principles as much as possible...fuck idk

oh right, my thinkpad is a t61 from 2008. her graphics suck enough she literally can't load games. not anything made past idk DX9 ?? however her discord experience is about on part w/ my envy 360 from over 10 years later. she's kinda sick tho. idk. will probably turn her into a media pc or some kinda server since she's got a 2600U w/ 8 threads.

i don't get youtube ads. i don't get tempted by the comments section, i don't have my watch history profiled. i have a local database of playlists (the video tab on a channel counts as a playlist btw) that i can sync and fuzzy search in the terminal and it'll play via the video player on my system. however, i don't get stuff recommended which makes finding stuff entirely active.

i gotta test and tweak games i wanna play bc old hardware and also usually running via compatibility layer (proton my beloved) on account of..well no linux-native version. or the native version has issues.

discord and screenshare don't pay niceys all the time. this is partly a discord enshittification issue but also the discord devs don't care about linux as a platform. they "support" it bc hey electron works there. because it's the fuckign chrome browser. audio support in screenshare is an unofficial feature added by volunteer devs and that's a breach of TOS bc that's the world we live in now.

my brain is full of init system trivia, audio services and routing frameworks, a ton of incomprehensible nonsense that marks the difference between nostalgia-bait and Actually Being Like This.

come on in, by all means ! let's learn the semantics behind vim's actions/keybinds, let's discover old parts of the net, build up an environment from its component pieces. let's suffer together as the separation of accounts forces the use of several different email addresses, a TOTP app, and renewed access tokens to play one (1) game online w/ friends.

i'm not futureshock cybercore cassette retropunk, i'm stubborn and refuse to engage in as much of the bullshit forced on us these days as i physically can.

More updates regarding PierMesh, peer id generation is handled by the node and sent to the peer's browser, node id is currently hard coded but that will change with some wiring. Further in the backend I've been wiring things together to finalize the refactor and I'm about to configure things so testing will be very simple

Note that the peer id is basically a local network address

[rabbiteclair]

step 1: build a professional-looking, ad-free site that will perform formatting and validation on a wide variety of file types used for configuration and data transfer (.properties, YAML, .config, JSON, etc), and decrypt file contents if people will just paste in their handy dandy private key/shared secret/etc. Yes, there are already sites for this stuff, but they're fairly scattered and ad-infested.

step 2: perform whatever SEO skullduggery is needed to get your site to the top of the Google search rankings.

step 3: once your site has established itself, pass every single thing that gets pasted into it to a backend service. If you wanna be coy about it, continue doing the validation in Javascript and pretend that the backend calls are metrics. Listen, if you make the URL something like https://admin.yourhosthere.com/datadog-agent then 90% of devs are gonna go 'yeah that seems legit, it's just my good friend Datadog :)' and investigate no further.

step 4: parse every message for strings like 'username' and 'password'.

step 5: now that you have production credentials for about 40% of international corporations and governments, hold the planet hostage.

step 6: rule the world from a flying volcano lair staffed with jumpsuit-wearing henchmen.

(traditionally the henchmen would come before the world conquest, but like most things, supervillainy has gone through massive changes thanks the internet)

WARNING: LONG ASK INCOMING

For hobby electronics there’s two major kinds of processors: Microcomputers and Microcontrollers. Microcomputers are small full computer systems like the Raspberry Pi, they typically run a general-purpose OS (typically some flavor of Linux) and are useful for the kinds of projects that require basically a full computer to function, but not necessarily individual sensors. They’re a great place to start for people who don’t know a whole ton about programming or working with individual components because they typically can output a true GUI to a screen and have the capabilities of a regular desktop computer. They have a main processor, true RAM, and either large on-board storage space or a way to read a storage device, like an SD card.

Microcontrollers are less complicated (component wise) than microcomputers, but as a result are more difficult for total beginners to begin working with. They’re typically primarily a SoC (System on a Chip) processor without discrete RAM modules and a very small EEPROM (on-ship storage space) and need to have components wired and configured to them to be able to do much more than being a fancy calculator. They’re used for when you need something to carry out electronic functions or get sensor readings, but not necessarily a full operating system, so they’re best suited for small/integrated applications. Your helmet uses a microcontroller to control the LEDs you used in the Cunt Machine post.

I build high-power model rockets as a hobby and with my university team, so I work with both kinds of processor as part of designing payload systems. I typically prefer microcontrollers in these as most of what we do doesn’t need an actual OS to run, and they’re smaller/lighter than microcomputers. One of the advantages of a microcontroller is that it runs a Real-Time OS (RTOS) which forgoes all the user-friendliness of things like windows and linux to instead be the bare minimum backend necessary to run code uploaded into the processor. 

The main advantage of using a microcontroller is really that they’re typically a lot cheaper than microcomputers are and are plenty powerful for really embedded applications. They also make other parts of whatever system is being built cheaper/easier to integrate because they require less overhead to function - the raspberry pi needs a minimum of 5 volts of power to work, while a chip like an ESP32-PICO can run at 1.8V. 

The main way you make sensors/buttons/peripherals work with a microcontroller is via digital communication busses. There’s a few protocols, the most common being I2C, SPI, and UART. I’ll talk about I2C since that’s generally the most common. With I2C each component is assigned a 2-byte “address” that they’re identified by. When the controller sends a request signal on the I2C data bus, every sensor along the line will return their own signal, marked with their address so that they can be identified. It allows for a large number of devices to be put on the same lines and you can daisy-chain them through each other to the microcontroller.

I’ll be honest I really can’t think of a good way to say much more on the subject as like a starting message because I’ve been working with computers so long all the tech stuff for me is second nature, but if you have any questions ask away I can probably answer them or google them.

Load Balancing Web Sockets with K8s/Istio

When load balancing WebSockets in a Kubernetes (K8s) environment with Istio, there are several considerations to ensure persistent, low-latency connections. WebSockets require special handling because they are long-lived, bidirectional connections, which are different from standard HTTP request-response communication. Here’s a guide to implementing load balancing for WebSockets using Istio.

1. Enable WebSocket Support in Istio

By default, Istio supports WebSocket connections, but certain configurations may need tweaking. You should ensure that:

Destination rules and VirtualServices are configured appropriately to allow WebSocket traffic.

Example VirtualService Configuration.

Here, websocketUpgrade: true explicitly allows WebSocket traffic and ensures that Istio won’t downgrade the WebSocket connection to HTTP.

2. Session Affinity (Sticky Sessions)

In WebSocket applications, sticky sessions or session affinity is often necessary to keep long-running WebSocket connections tied to the same backend pod. Without session affinity, WebSocket connections can be terminated if the load balancer routes the traffic to a different pod.

Implementing Session Affinity in Istio.

Session affinity is typically achieved by setting the sessionAffinity field to ClientIP at the Kubernetes service level.

In Istio, you might also control affinity using headers. For example, Istio can route traffic based on headers by configuring a VirtualService to ensure connections stay on the same backend.

3. Load Balancing Strategy

Since WebSocket connections are long-lived, round-robin or random load balancing strategies can lead to unbalanced workloads across pods. To address this, you may consider using least connection or consistent hashing algorithms to ensure that existing connections are efficiently distributed.

Load Balancer Configuration in Istio.

Istio allows you to specify different load balancing strategies in the DestinationRule for your services. For WebSockets, the LEAST_CONN strategy may be more appropriate.

Alternatively, you could use consistent hashing for a more sticky routing based on connection properties like the user session ID.

This configuration ensures that connections with the same session ID go to the same pod.

4. Scaling Considerations

WebSocket applications can handle a large number of concurrent connections, so you’ll need to ensure that your Kubernetes cluster can scale appropriately.

Horizontal Pod Autoscaler (HPA): Use an HPA to automatically scale your pods based on metrics like CPU, memory, or custom metrics such as open WebSocket connections.

Istio Autoscaler: You may also scale Istio itself to handle the increased load on the control plane as WebSocket connections increase.

5. Connection Timeouts and Keep-Alive

Ensure that both your WebSocket clients and the Istio proxy (Envoy) are configured for long-lived connections. Some settings that need attention:

Timeouts: In VirtualService, make sure there are no aggressive timeout settings that would prematurely close WebSocket connections.

Keep-Alive Settings: You can also adjust the keep-alive settings at the Envoy level if necessary. Envoy, the proxy used by Istio, supports long-lived WebSocket connections out-of-the-box, but custom keep-alive policies can be configured.

6. Ingress Gateway Configuration

If you're using an Istio Ingress Gateway, ensure that it is configured to handle WebSocket traffic. The gateway should allow for WebSocket connections on the relevant port.

This configuration ensures that the Ingress Gateway can handle WebSocket upgrades and correctly route them to the backend service.

Summary of Key Steps

Enable WebSocket support in Istio’s VirtualService.

Use session affinity to tie WebSocket connections to the same backend pod.

Choose an appropriate load balancing strategy, such as least connection or consistent hashing.

Set timeouts and keep-alive policies to ensure long-lived WebSocket connections.

Configure the Ingress Gateway to handle WebSocket traffic.

By properly configuring Istio, Kubernetes, and your WebSocket service, you can efficiently load balance WebSocket connections in a microservices architecture.

Fully managed vps hosting services

The timing may be appropriate for you to move to best VPS Hosting if you currently have a shared server for your website and experience regular website downtime.

Shared hosting may not be suitable for managing resource-intensive websites and may have some constraints depending on the web hosting provider.

Because numerous websites use a shared server's resources, they may also experience problems handling high visitor volumes. Affordable VPS Hosting offers dedicated resources for your website, and it is widely seen as a logical step from shared hosting. 

How Does VPS Work?

Virtualization is a technology used by VPS hosting that divides a single server into several virtual servers, each with its own operating system, applications, and resources. A hypervisor, a software layer that controls and distributes the physical resources to the virtual machines, is used to do this.

A website hosted on a shared physical server cannot be impacted by other VPS users because each one is allotted a specific part of the server's resources by the web hosting service provider. At a fraction of the price of a dedicated server, this isolation and dedicated resource allocation offer a similar performance and control level.

Virtual private servers (VPS) are highly sought after nowadays; telecom companies, healthcare institutions, and retail establishments frequently use various VPS options.

While maintaining pricing substantially lower than dedicated servers, the affordable VPS hosting plan delivers far greater security and performance than shared hosting. With the addition of advanced customizations and greater scalability, you have a solution that can handle almost any task.

Not everyone has the budget or ability to hire a dedicated administrative assistant. Naturally, the normal business owner would rather focus on expansion and development, leaving the details to the experts. This is the context in which managed services are useful.

What is Managed Hosting?

With a Managed Hosting package, the web hosting service provider handles all of the backend's primary responsibilities, including server maintenance, application installation and upgrades, and extensive security monitoring. 

What is Managed VPS Hosting?  

Here, the web hosting service provider is in charge of handling all significant services pertaining to the configuration, upkeep, backup, update, and security of the VPS server. For those who don't want to spend a lot of time on these problems or who don't know how to configure a server, managed virtual server hosting is the ideal option.

It relieves the client of a significant portion of their workload so they may focus on other facets of their organization.

The web hosting provider handles a number of tasks, such as setting up servers, installing software, handling security issues, and providing technical assistance.

What do Managed VPS Services Include?

Various hosts might respond to the question in different ways.

Some people claim that if a VPS hosting service only receives server maintenance and software upgrades, it qualifies as "managed." Others believe that further services like security assessments and malware removal ought to be offered. Some are even open to helping with development suggestions.  

Contacting your web hosting service provider in advance is the only way to find out precisely how much help they can provide with administering your VPS server. A pre-sales consultation can clear up all doubts.

What is the support team's view? How can you contact them? Do they operate around the clock? Who is responsible for installing and updating software?

Acquiring these particulars in advance is the only method to know exactly what to anticipate.

The majority of popular managed VPS services plans come with the following features by default:

The following services are offered:

A commitment to uptime

server provisioning and setup;

control panel and server management tools;

installation of security software;

regular updates and vulnerability patches;

offsite server backups;

on-demand malware scans;

resolution of hardware and software issues;

and round-the-clock assistance.

A reputable virtual server provider may relieve you of a great deal of responsibility, particularly in terms of security.

Acknowledging the necessity for timely and well-supported web hosting services is a fantastic place to start, but there are a lot of hosting companies in the market, and they all want your business. To make sure you make the best choice, you must conduct thorough research.

How to Choose a Managed VPS?

It's crucial to find a reliable partner to assist you in your VPS attempt. There are a few more things to think about before jumping into the first profitable trade you come across.

Features: Examine each host's feature list to determine which will be most helpful for your project. Also, examine the remaining material; frequently, you may have overlooked certain future requirements.

Resources and Expandability: Since your VPS machine's CPU and RAM are its main components, start with them. Verify that you have adequate monthly bandwidth and storage space. Making use of SSD discs is strongly advised. Ensure that you have space to expand. All of the top-managed virtual private server providers are easily scalable, allowing you to add or remove resources as needed.

Achievement: Even before you sign up as a client, you can assess the speeds of your possible host. It's best if your provider offers a free trial or demo tour. Just sign up, create a basic website, and then use a third-party tool to analyze the website's performance. Do several tests to prevent false positives.

Uptime: Uptime is a little more difficult to check because it takes longer. However, you can always review previous customer feedback to ensure a clear return policy in the event of unplanned outages.

Usability: Usability especially helpful if you've never used a managed virtual private server before or if you don't have the technical know-how to administer one. Once more, a lot of sites let you try out the UI and navigation so you can make sure your pick of hosting will work well for you before committing any money.

Support: This is frequently the most important element. While every service can claim to provide 24/7 support, only some truly succeed in doing so. Pre-sales talks with your possible options are highly recommended as they will provide you with a solid understanding of the kind of support you can expect as a client.

Is there help available around the clock? How quickly do they react? Do they have the knowledge to assist with more complicated problems? Do the operators make an effort to comprehend your situation, or do they just provide links and pre-written answers?

These are but a handful of the queries you may use to find out how well-managed your VPS is supported.

Cost: Although shared hosting is often cheap than virtual servers, the price differential is closing every day. However, don't limit your search to the lowest prices; what matters more is the feature-cost ratio or what you truly receive for your money. It all comes down to your demands.

For example, you wouldn't need better e-commerce functionality if you weren't operating an online store, nor would you need a system with 16 CPU cores and 12 GB of RAM to operate a small company website.

Establish your objectives and a plan of action to achieve them; your managed VPS provider may assist with the rest.

Benefits of Managed VPS Hosting-

Greater Reliability: If you choose the Managed VPS plan, the provider will be in charge of making sure your server is always accessible to the website. The resources given for each virtual private server are not shared with other websites because each server operates independently of the others and is in a storage tower.

In contrast to Shared Hosting, wherein the actions of one website could directly affect all other websites, a best VPS Server is more capable of withstanding spikes in traffic without overloading itself. This guarantees that the server for your website is more available, which improves the uptime score.

Optimal performance: When you choose a Managed VPS plan, the web hosting provider company ensures that your server is operating at its best. The server's performance is not affected as you allocate resources specifically for your website, which progressively speeds up the time it takes for pages to load.

One cannot overstate the significance of a website's speed. The SEO algorithm's consideration of website speed and its direct correlation with improved user experience has elevated the topic of website speed in webmaster discourse.

Improved Security: With the rising number of cybersecurity threats, security continues to be a top concern for website owners. One drawback of cheap shared hosting is that every website on the same server has the same IP address.

The possibility of all websites being impacted by a single website's security breach is always there. However, each virtual environment included in the managed VPS plan has its own IP address, so your website is unaffected by the security of other websites.

A managed VPS hosting service regularly installs and updates security patches to defend against cybersecurity threats.

Greater Control: With managed VPS plan, you have total root access to the server. You can install the operating system and additional programs of your choosing. However, this might require technical know-how, and there's a chance your server access could be locked.

For those who fit this description, it is best to choose Managed VPS Hosting and delegate most of the duties to the hosting provider. However, the client still retains last say over the server.

Customer service: By taking full control of the server management with a Managed VPS plan, the hosting provider can provide more committed technical assistance.

Depending on the service provider, you may also have personal assistants to handle all of your needs.

Conclusion-

The popularity of managed VPS hosting is rising for a good reason. Our comprehensive solution caters to both small and large businesses, offering benefits like increased security, performance boost, and personalized assistance. Another major benefit is that scaling your CPU, RAM, or server space allows you the control and flexibility to meet increasing demands. Since the expenses are frequently linked to the number of resources you use, you may forget about overpaying.
