Alien Romulus & how (not) to optimize your slasher cast dynamics

Much as I enjoyed Alien: Romulus it made the cardinal horror movie sin of killing off the cast in the wrong order for maximum interpersonal carnage.

If your established cast is the hero, the villain, the villain's partner, the hero's partner, and the woobie, killing off the villain's partner and then the villain, leaving only the characters who know and like each other to work together has much lower peak potential for dramatic tension among all possible configurations.

Firstly, there should have been more panic when Navarro died. She was the pilot. How are they meant to get off the ship without their pilot? (Yes, the autopilot exists, but that's a plot contrivance they could find out about later - or they might have to scavenge a new part from the ship to add to their damaged smaller vessel to add autopilot functionality to it. Or, perhaps, Andy can be the autopilot - but that requires Andy getting off the ship which requires convincing the AI upgrade within him to do so - which would be another layer of complication.)

But anyway the ideal next candidate to die is Tyler. Tyler is the peacekeeper between Bjorn and Andy, and the link between Rain and the rest of the remaining crew, who are all family members. (Even before we get to Kay and Bjorn being exes or ex hookups)

Remove Tyler from the remaining cast and Bjorn and Rain immediately have a power struggle. Bjorn hates androids, but they need the android to escape the ship. Neither Andy or Rain like Bjorn, but he is an extra person to use as defence in a situation where they can't afford to make their party any smaller. Bjorn also has immediate personal beef with the aliens as they killed his partner, Navarro - so will be a loose cannon if they ever come across aliens. But, he also has Kay to protect now - the mother of his unborn child.

And, sorry to be gross, but it is the horror genre - imagine the magnification of the horror element if, at the end, when the alien-baby hybrid is born, if not just it's mother but it's father is also still alive there. Or if Bjorn has been hurt by the acid blood still and he and Kay have to choose between them which of them they will use the black goo to save, not knowing that whoever takes it is damning themself to become the next alien host. Or if Kay and Bjorn think they are safe and have escaped, and Bjorn, who has now bonded with and come to respect Andy through their adventure together now calls out to Andy for help against the alien as they are escaping in their escape ship, because he trusts him now and thinks he will save him - but Andy's protocols to do what's best for Rain have at that point been turned back on and so Andy cannot put Rain at risk even to save Bjorn and Kay after all they've been through together.

Now that's how to write a real horror on all levels.

ok time for wifi troubleshooting dump (for Windows but the concepts are true for any device)

First, how this happens. Imagine you had a router that wasn't plugged into anything but power, and a laptop with an ethernet port. If you plugged the laptop into the router, you would get a similar message of "connected without internet" but it would show an ethernet icon with instead of wifi icon.

What that error means is that you did, in fact, connect to the wifi. That's layers 1 and 2 of the internet. Trouble is, there's more layers, and you need all the layers to use the internet.

Layer 3 of the internet is the Routing layer. Yes, this is where the name "router" actually comes from, but I digress. This is the layer of the internet that deals with "IP addresses". Where your computer or your phone or TV or whatever normally gets an IP address from is something called "DHCP". Dynamic Host Configuration Protocol.

You don't need to memorize that. Just know that after you connect to a network with wifi or ethernet cable, one of the first things device will do by default is send a broadcast on the network asking "Hey! Is anyone here a DHCP server?" This works because certain sorts of broadcasts don't need your computer to know how to use the network more than just being connected to it.

The addresses used when asking this are actually 0.0.0.0 and 255.255.255.255. If those sound like special addresses, that's cuz they are. "no address" and "everyone who can hear this". Anyways...

Your home router by default is running a dhcp server on it, so it SHOULD hear this broadcast and it SHOULD respond and your computer SHOULD negotiate whats called a "DHCP lease". This basically is just a bit of information saying "ok so here's your address and subnet size, here's your default gateway, here's some DNS servers, it's good for [LENGTH OF TIME HERE]."

The first thing to check is, did DHCP work? Right-click the network icon, whether ethernet or wifi, and chose "Open Network and Internet Settings".

Then go to the network properties of either the ethernet or the wifi, whichever one you're connected to.

Yours won't say "connected" cuz yall internet is broken but the buttons are still there.

The big thing you're looking for is the "IPv4 address". IPv6 is different don't worry about it right now and usually if IPv4 is broken then IPv6 is broken anyways, if your internet provider even serves you IPv6... ANYWAYS.

If you have an address like 192.168.something.something or 10.something.something.something you probably got a DHCP lease so that's not the issue.

If you have an address like 169.254.something.something then that means that either the DHCP server didn't respond, or it did respond but your wifi signal is so bad that your computer didn't hear the response.

Restart your router, look into changing the wifi channel settings on the router to a less occupied channel, try using 5ghz wifi if possible though not everyone's computer or router supports that, sometimes restart your computer cuz sometimes Windows' networking software does stupid thing.

Also, unless you KNOW you're supposed to be using Static addressing, make sure you're set to Automatic. Someone may have turned off Automatic addressing cuz they're a prankster. Or they don't know what they're doing. Or both.

Well, if you got to this point because you aren't having a DHCP issue, then things get a little tougher cuz the "internet is out and you should call your ISP to find out if it's a wider outage that they're already working on fixing or if it's just you" possibilities start to show up now.

Time for Command Prompt. I promise it's not nearly as scary as you might think.

Alright, time for our first command. Type in "ipconfig" without the quotes, and hit enter. It'll spew out a bunch of text at you, but it's not as complicated as it looks.

I crossed the things in thick red out cuz I don't trust tumblr to not pull some shit, and the one thing in thin orange because it's fine if people see that but it's in the middle of some stuff we want.

Yall have used Discord at some point, right? You see that Default Gateway? We're gonna ping it. "ping 192.168.1.1" or put whatever your gateway is instead.

I'm on ethernet with properly functioning equipment, so my ping delay is <1ms (less than 1 millisecond). Wifi is gonna be higher, anywhere from 10 to 200 milliseconds, depending on your wifi quality.

Also, if your wifi connection is really bad, you may see "Request Timed Out".

If you're having trouble pinging the gateway, you may want to do a ping test. Adding a -w 50 (wait 50 milliseconds) will make the computer not wait long for failed pings, and -n 40 will make it try 40 times instead of just 4 times, cuz we need more data than just 4 tries.

This'll take a while to run (about 40 seconds to be exact). If you get tired of it running or just everything is timing out constantly then you can press Control C (like copying something in a text editor) to interrupt the program.

The big things to pay attention to are the "round trip times" and the % loss.

If your % loss to the gateway is 100% then either your computer is configured wrong and you should check that you're using the right addressing, or your wifi is extremely bad, or extremely rarely your router doesn't respond to pings on its local network. This is almost never the case. Your router probably doesn't respond to pings from the internet for security reasons, but pings from the inside are good for troubleshooting.

If your % loss to the gateway is over 10%, and/or your times are consistently very high (over 100ms or so) then your wifi conditions are extremely bad. Either you don't have enough signal strength, or there's heavy interference and basically your computer and router are effectively trying to have a conversation while at a loud metal concert. Neither of them can hear eachother very well.

There might be something wrong with your internet service provider still; but if you were wondering why using your wifi is suffering even when the internet isn't out, that's a hint.

If your % loss to the gateway is over 1% but under 10% then that's Not Great and you should still look into wifi channelization but it wouldn't stop you from being able to use the internet entirely.

Under 1% is okay, that means it's not a wifi issue.

The next thing to try is to ping a well-known usually-up service, such as Cloudflare Public DNS (1.1.1.1) or Google Public DNS (8.8.8.8) or Quad9 (9.9.9.9)

My internet is working fine, so I have 0 loss and while there is some variance (one got 34ms instead of 11) everything looks peachy.

If your pings to one of these public services all fail, then either your router needs to be configured because either 1. it wasn't set up in the first place (you would not believe how many people I take calls from that have this issue) or 2. it factory reset itself for some reason (some people think that rebooting the router means use the reset button. IT DOES NOT MEAN THAT.) and you need to pay attention cuz if it happens again that may mean ur router is screwed.

Or, there's an actual service outage, and you should call your ISP to find out if it's just you, or if it's a general outage and they're already working on it and all you can do is hurry up and wait.

And... that's it. There are other weirder issues that you can have, sure. As long as this post is, explaining some of those issues would take even longer. And I would LOVE to explain some of them. But this post is already more than long enough, and it covers the vast majority of cases.

Thank you for reading and good luck!

when the wifi says "connected without internet" how about i fucking kill you

How LiteSpeed Improves Loading Speed

Website speed is a critical factor in user experience, SEO performance, and conversion rates. Faster-loading websites engage visitors better, reduce bounce rates, and rank higher in search results. LiteSpeed Web Server (LSWS) is engineered to optimize website speed with powerful technologies built into its core. This article provides a technical and practical look at how LiteSpeed improves website performance, its architectural strengths, and comparisons with other web servers like Apache and NGINX.

What Is LiteSpeed?

LiteSpeed is a high-performance web server software developed by LiteSpeed Technologies. It serves as a drop-in replacement for Apache, meaning it can use Apache configurations such as .htaccess and mod_rewrite while offering far superior performance.

Unlike traditional web servers that rely on process-based or thread-based architectures, LiteSpeed uses an event-driven approach. This enables it to handle thousands of simultaneous connections efficiently without consuming excessive resources. It’s widely used in shared, VPS, and dedicated hosting environments due to its scalability and speed.

LiteSpeed is compatible with major web hosting control panels like cPanel, Plesk, and DirectAdmin. It also integrates seamlessly with WordPress, Magento, Joomla, and other popular CMS platforms.

How LiteSpeed Improves Loading Speed

LiteSpeed's performance is not just theoretical. Numerous benchmarks and case studies show significant improvements in load time, server response, and concurrent user handling. Its technical foundation plays a pivotal role in enabling these advantages.

Event-Driven Architecture

Most traditional web servers like Apache use a process-based or threaded architecture. Each connection requires a dedicated process or thread, which leads to high memory usage under load.

LiteSpeed uses an event-driven, asynchronous model. It processes multiple connections within a single thread, significantly reducing memory consumption and CPU load.

For example, benchmarks by LiteSpeed Technologies show that LSWS handles over 2x more concurrent connections than Apache with the same hardware configuration [1]. This architecture is especially beneficial during traffic spikes, such as flash sales or viral content events.

Built-In Caching (LSCache)

LiteSpeed’s caching engine, LSCache, is built directly into the server core. Unlike third-party caching plugins that operate at the application level, LSCache works at the server level, making it faster and more efficient.

With LSCache enabled on WordPress, testing from WPPerformanceTester shows up to 75% reduction in page load times compared to uncached sites. This is because LSCache delivers prebuilt HTML pages directly to users, bypassing PHP execution and database queries.

LSCache also supports advanced features such as:

ESI (Edge Side Includes) for partial page caching

Smart purging rules

Private cache for logged-in users

Image optimization and critical CSS generation

These features make it suitable not only for static pages but also for dynamic, eCommerce-heavy platforms like WooCommerce or Magento.

Compression and Optimization

LiteSpeed supports GZIP and Brotli compression out of the box. These technologies reduce the size of files transmitted over the network, such as HTML, CSS, and JavaScript.

According to Google PageSpeed Insights, compressing assets can reduce page size by up to 70%, which directly improves load time. Brotli, developed by Google, provides even better compression rates than GZIP in many cases, and LiteSpeed uses it efficiently.

Additionally, LiteSpeed can minify JavaScript, CSS, and HTML, combine files to reduce HTTP requests, and enable lazy loading for images—all directly from the server level.

QUIC and HTTP/3 Support

LiteSpeed is one of the earliest web servers to fully support QUIC and HTTP/3, protocols developed by Google and later adopted by IETF.

QUIC is built on UDP instead of TCP, which reduces handshake latency and improves performance over poor network conditions. HTTP/3 inherits QUIC’s benefits and introduces faster parallel requests and better encryption handling.

When HTTP/3 is enabled, page loads feel snappier, especially on mobile devices and in regions with weaker connectivity. Cloudflare reported up to 29% faster page loads using HTTP/3 versus HTTP/2 [2].

LiteSpeed’s implementation ensures that your site is future-ready and delivers optimal performance even under challenging network environments.

LiteSpeed vs Apache and NGINX

Performance benchmarks consistently show that LiteSpeed outperforms both Apache and NGINX in various scenarios, especially under high traffic and dynamic content conditions.

Apache Comparison

Apache is widely used but is resource-heavy under load. When serving PHP applications like WordPress, Apache relies on external modules (e.g., mod_php) or handlers like PHP-FPM, which increase overhead.

LiteSpeed replaces these with LiteSpeed SAPI, a more efficient PHP handler. Benchmarks show that LiteSpeed can process 3x more PHP requests per second compared to Apache [3].

NGINX Comparison

NGINX is known for its speed with static files, but it lacks full .htaccess compatibility and requires more manual tuning for dynamic sites.

LiteSpeed combines Apache’s ease of configuration with NGINX’s speed and goes further by offering built-in caching and QUIC support. This makes it a more all-in-one solution for both static and dynamic content delivery.

Real-World Results

A hosting provider, NameHero, migrated over 50,000 sites from Apache to LiteSpeed. The result was an average decrease in load time by 40%, with no change in hardware configuration [4].

Another example is a WooCommerce store that used LiteSpeed Cache. Load times dropped from 4.2s to 1.2s after activation, significantly improving Core Web Vitals and user retention.

Website owners consistently report faster Time to First Byte (TTFB), better PageSpeed scores, and fewer server crashes during traffic peaks when using LiteSpeed.

Who Should Use LiteSpeed?

LiteSpeed is ideal for:

WordPress users who want faster page loads without complex configurations.

WooCommerce and Magento store owners needing efficient dynamic caching.

Web hosting providers looking to reduce server load and increase client satisfaction.

SEO-focused marketers who want better Core Web Vitals.

Developers who want Apache compatibility with modern performance.

LiteSpeed is available in both open-source (OpenLiteSpeed) and commercial versions. While OpenLiteSpeed is suitable for smaller projects, the enterprise version offers advanced features and full control panel integration.

Final Thoughts

LiteSpeed offers a clear performance advantage due to its architecture, built-in caching, modern protocol support, and optimization features. It helps websites load faster by minimizing server load, reducing latency, and delivering content more efficiently.

Whether you're a developer, site owner, or hosting provider, switching to LiteSpeed can result in measurable improvements in speed, stability, and scalability. In today’s performance-driven web ecosystem, LiteSpeed is a practical solution backed by real results and advanced engineering.

Introduction   Virtual network is a system that composed of virtual machines that are usually configured to manage or process external or internal network resources. This system is often configured to function with a network adapter especially when using a physical computer or work without adapter when using virtual machines (Lowe, 2011). Different networks often respond to different machines in a specific manner (Simpson, and Novak, 2010). Connecting a network adapter to a physical computer requires a virtual machine to be connected or linked to a virtual network to which the physical adapter is connected. When the adapter is not used, the virtual machine connected to the virtual network forms part of the internal virtual machine (Oppenheimer, 2005). It is worth noting that the internal virtual machine networking usually consists of all other virtual machines connected to the virtual network that is configured to function without network adapter. In this case, every internal virtual machine network is isolated completely from other systems of internal virtual machine network. Fig. 1. An example of a virtual network design (VMnet virtual network design (Lowe, 2011)) It is worth noting that the Virtual Server supports a significant number of virtual networks; therefore, virtual network can serve many or unlimited virtual machines that are connected to it. Using the virtual DHCP Server The virtual Dynamic Host Configuration Protocol (DHCP) Server is usually part of the virtual network. It provides that IP address that it leases only to the virtual machine. The main advantage of the DHCP is that it can be used instead of configuring the virtual machine to a DHCP server since DHCP usually disable it by default. Therefore, if the virtual network is linked to the adapter of the physical network and the virtual DHCP server is activated, the DHCP server will be expected to isolate from the operating system of the host and all other virtual machines. Despite being isolated, the DHCP server will still assign unique IP addresses to the virtual machines and within a specified range. In the case above, the DHCP server is configured to only use for the IP address of 10.244.0.254 as the range within which the IP address range commences (Simpson, and Novak, 2010). Therefore, the system above is expected to assign the IP addresses ranging from 10.244.0.16 to 10.244.0.254 for all the virtual machines attached to the same DHCP’s network. Configuring Multiple Virtual Networks A single network adapter can be associated with multiple virtual networks. In this case, the created virtual network is associated with the physical network adapter within the virtual network system. This linking mode will enable linking numerous the 75 and 100 virtual machines to a system of virtual network. If the organization will need multiple virtual networks to be connected to its host operating system, then there will be needed to create additional virtual network (Daft, Murphy, and Willmott, 2010). This will be achieved through a repeated procedure (Oppenheimer, 2005). However, if the organization wants to configure the virtual machines without network connectivity, then the virtual machines will not be connected to the virtual network. It should be noted that the creation of the virtual network automatically configures a network file that is stored in the cloud. Moreover, the virtual network configuration automatically allows files, documents and settings, document sharing, and all users to access to share the folders in the virtual network. Therefore, only a few or a single central server will be used by all users who require the same information from the same source or server. Read the full article
