Last Monday of the Week 2024-12-09

Continually looking up "what day is christmas" and then forgetting almost immediately. This is not a bit I keep forgetting whether it's the 23rd the 24th or the 25th.

Listening: Bandcamp Friday! Posted about that here:

Watching: Not much.

Reading: A mix of 3D printing stuff and, still, work research, mostly about network configuration, because I'm trying to run a stupid complicated mlag vlan setup with trunked ports on the host side which is especially hard because this is basically my first time touching managed network hardware. Everything I know about vlans until like two weeks ago is theoretical.

3D printing stuff involves both some materials science and some interesting basic introductory stuff on hybrid fluid dynamics and solids simulations that because I want to try and do some structural simulations, it looks like there's some plugins for OpenFOAM that render this doable, just.

Making: New printer! Some test prints to get that up and running. Aborted a skull print because it seems like the printbed this came with is much less sticky than I'm used to, figuring out how to use that correctly.

Trying to fix the dead Ender 3 SE, which appears to have kerploded its power supply dramatically, link to that saga here

Some quilting with my partner, we are good at very different parts of sewing, they do knitting and crochet and worked shop tailor work for a while but are pretty weak at hand sewing, I do a lot of hand sewing and embroidery but I only barely know how to knit and crochet scares me.

Playing: A lot of Cyberpunk 2077, which I picked up in the steam sale as my one Big Game.

I have a lot of thoughts. This has very good writing for a Video Game RPG, especially one with such limited dialogue. I think being fictional helps its world feel much more real than say, GTA V, which is good at simulating a lot of things but I think struggles with the final hurdle, despite being in many ways much deeper than Cyberpunk.

Playing on Hard, which I think is a nice balance of letting your actions actually deal damage and feeling as deadly as Cyberpunk games are meant to feel.

Tools and Equipment: Compact powered screwdrivers are a real godsend, I have that Xiaomi multibit set and it's really worth the price of admission when you're working on something that is just full of screws.

Anonymous asked:

Really awesome post! 🙇‍♀️ Some of what you shared is beyond my understanding 😅 but that also makes it educational (thank you for the links to sources, that HEVC haunted link!) Also the bit about upscaling decisions 🥲 I don't think we can make assumptions about how long things last on the "internet" (harder to find 🥲, removed/made private, etc.), so I definitely appreciate your effort to archive/back up stuff 🫰🙇‍♀️

This is a fake ask because I wanted to remove the links at the bottom (I appreciate them, just nervous about re-sharing) but did want to respond to the rest of it. Specifically, if you are even moderately interested in my nerd tangents, I cannot pass up the opportunity to gush about how cool RAID is as a concept.

You’re right that everything on the internet either lasts forever or just not long enough for you to save it, depending on what is most inconvenient at the time. It is both an access and a preservation problem. The YouTubes of the world aren’t likely to lose data accidentally (just deliberately stop you from seeing it) but as soon as you start trying to make personal backups you have to factor hardware failure into the equation. Disks fail. Backblaze publish some cool statistics on exactly how often. Keeping a backup of anything critical on a single hard drive is playing with fire, it's not a matter of if, it's a matter of when if you have plans to keep it for more than a decade (although they do show warning signs, so if you're regularly monitoring S.M.A.R.T test results its less likely to happen completely out of the blue).

My backups are currently stored in a RAID 5 configuration (specifically, a ZFS RAIDZ1 pool). That means I can yank any of the four disks out at random and everything will continue operating completely normally. In the event of a drive failure, inserting a new empty drive of equal or greater capacity will allow the system to rebuild the content the old one was holding onto the new one, resulting, upon completion, of a configuration that once again allows any disk at random to be pulled without data loss. The main vulnerability here is that two failures in quick succession are completely unrecoverable (the contents of 2/4 drives are utter gibberish and cannot be deciphered without at least one more from the original pool). My drives are purchased from different batches but from the same manufacturer, so there is still potential for common cause failures (one of the risk factors also just being that they are of similar ages). When I originally built this system I was happy with the level of risk involved with a rebuild event, but recently I've been thinking recently of moving it over to a RAIDZ2 (two disks of redundancy) instead. It isn't possible to "upgrade" an existing pool like that you have to do a complete rebuild, but my friend has an external backup server on my local network (well, its not, it's currently in a separate VLAN, but that can be changed) I can use to temporarily shift my stuff over to before moving it back. The new pool would be 6 wide with 2 disks of redundancy as there's no point in RAIDZ2 with 4 disks (that's just a mirrored pool) so I would also gain a disk's worth of capacity in the progress, but lose two disks worth of money from my bank account, which is why I haven't done it yet.

Oh also, as a final note, computers are not as infallible as they are made out to be. While the chance is very low, it is never zero that a cosmic ray causes a bit flip somewhere critical and unrecoverable to the program which needed it. Ever had a completely random crash that you've never been able to reproduce? Well, it probably wasn't a cosmic ray. But it could have been! This is the kind of stuff I think about for a living ;)

Meaning of Bare Metal Server?

To understand the meaning of a bare metal server let’s understand the meaning of a web server, A web server can be said to be software or hardware that stores all the website’s files responds to client requests, and delivers the required files accordingly via the internet. The Meaning of Bare Metal server in simplest words can be said as a server that is created for a single person only with the most premium technology that can be availed in a physical server only i.e. it cannot be available virtually.

Meaning of Bare Metal Server

A bare metal server is a physical server, it is a kind of server that is dedicated to a single tenant, In a virtualized server the hardware resources such as CPU, RAM, Storage etc. are shared while here all of the resources are used by a single person only and are chosen as per our choice, as there is no co-dependency in this kind of server it not only facilitates the increased performance of the server but also reduces hustle as it removes additional layers of software that are put into making server services available virtually.

Here there’s also an additional benefit of making the server as customized as possible, As there is only a single user and the server is available physically, It can be created to please and cater to your needs. let’s understand how it can be customised to an extent:

Personalized selection of hardware components such as CPU, type of RAM, and Storage.

There can be an option to choose any kind of Operating System that is compatible with your website

In a bare metal server, you can have firewall rules to suit your application’s requirements which include defining IP addresses, setting up virtual LANs (VLANs), managing network security policies, etc.

In a bare metal Server, there is access to the server’s BIOS (Basic Input/Output System), which allows for low-level hardware configurations, such as hardware virtualization settings, and power management options.

Understanding the Difference between a Dedicated Server and a Bare Metal Server

As the working of bare metal server and dedicated server is quite similar, they both have resemblance such as they both are dedicated to a single tenant but they can’t be said as the same, The root difference doesn’t lie in the product but the working of the server the concept of bare metal servers arrived after some drawbacks of a dedicated server.

While a dedicated server provides multiple benefits it has some inevitable drawbacks such as dated hardware and long provisioning times. However, bare metal servers typically come with the most advanced hardware and software. They are a hosting provider’s prized asset or flagship because bare metal servers are specifically made to automate the provisioning process, they may be put up more quickly.

The hardware provided by bare metal servers is considerably more similar to a cloud service framework, with installation durations measured in minutes or hours and hardware ranging from low-cost to Top-of-the-line components, including graphics processing units (GPU). When it comes to hardware, bare-metal servers have an advantage thanks to their use of the most recent Intel Xeon processors, DDR4 RAM with Error Correcting Code (ECC), and NVMe solid-state drives (SSDs) rather than SATA SSDs and hard drives. Because of the combination of these components, In conclusion, bare-metal servers stand out as a high-performance hosting solution.

How Managed Switches Are Transforming Smart Factory

Enabling Centralized Network Control for Streamlined Operations

By facilitating centralised control, managed switches are essential to streamlining network administration in smart factories.

Network administrators can configure, monitor, and troubleshoot all connected devices from one place thanks to an easy-to-use interface. This centralised visibility improves overall operational efficiency and speeds up response times during faults.

Everything can be controlled remotely, including traffic monitoring, VLAN configuration, and security policy implementation.

 In addition to reducing the amount of manual intervention, this capability enables proactive maintenance and speedier decision-making.

Consequently, factories are able to maintain optimal performance throughout their entire network, minimise downtime, and accomplish smooth communication.

Enhancing Network Reliability with Redundancy Protocols

Continuous network connectivity is essential for sustaining operations in smart factory settings.

 Redundancy protocols like Rapid Spanning Tree Protocol (RSTP) and Spanning Tree Protocol (STP), which establish alternative communication channels within the network, are supported by managed switches.

These protocols ensure minimal disruption by automatically rerouting data traffic through backup links in the event of a link failure.

By lowering the chance of expensive downtime, this inherent fault tolerance helps maintain high network availability.

 Managed switches give smart factories the resilience they require to enable automation, real-time monitoring, and data-driven decision-making by promptly identifying and fixing network loops or failures.

Boosting Efficiency Through VLAN-Based Traffic Segmentation

In smart factories, managed switches that support virtual LANs (VLANs) are crucial for managing and streamlining network traffic.

VLANs keep unnecessary traffic from straying into unrelated areas by dividing the network into distinct virtual zones, such as production, administration, and security systems. By restricting access to sensitive data, this isolation improves data security and eases congestion by ensuring that data stays on its intended path.

Critical applications thus get the bandwidth they require, enhancing network performance as a whole.

In addition to making complex industrial environments easier to manage, VLANs streamline maintenance and troubleshooting while guaranteeing effective and secure communication between all departments.

Supporting Real-Time Communication with QoS Prioritization

Real-time communication is crucial to the efficient operation of automation and control systems in smart factory settings.

 Quality of Service (QoS) features on managed switches give priority to important data traffic over less urgent transmissions.

This guarantees that even during times of high network load, time-sensitive operations—like sensor feedback, machine control, or safety alerts—are delivered without interruption.

 QoS contributes to the network's low latency and high reliability by giving priority to important packets.

This is particularly important in industrial automation, where safety and operational efficiency are directly impacted by snap decisions and constant data flow.

Powering IoT Devices with PoE for Simplified Connectivity

Power over Ethernet (PoE), which enables the delivery of both power and data via a single Ethernet cable, is revolutionising smart factory networks.

Installing IoT devices like IP cameras, sensors, access points, and control panels is made easier by managed switches with PoE capabilities.

 This cuts down on installation time and expenses by doing away with the need for additional wiring or separate power supplies.

 Managed PoE switches also provide remote power management, which enables administrators to keep an eye on and manage how power is distributed to linked devices.

 This supports a flexible, scalable, and affordable infrastructure for smart manufacturing systems, which is particularly useful in expansive or difficult-to-reach locations.

How VLANs Work on a Network Switch: A Simplified Explanation

What Is a VLAN and Why Do We Need It?

A VLAN, or Virtual Local Area Network, is a technology that allows you to logically divide a physical network into separate, isolated segments.

 Devices can be grouped into distinct VLANs to improve organisation and manage traffic flow, even if they are physically connected to the same switch. By reducing pointless broadcast traffic, this division enhances network performance and efficiency.

VLANs are perfect for settings like offices, schools, or large buildings where various departments or user groups need isolated network access without requiring additional physical infrastructure because they also add a layer of security by limiting access between groups.

How Network Switches Handle VLAN Traffic

How VLAN traffic is handled by network switches Network switches ensure that traffic is appropriately segmented by managing VLAN traffic by tagging data packets with VLAN IDs. Every VLAN has a unique ID, and the switch tags devices with the relevant VLAN ID when they send data.

Until a router or Layer 3 switch is used to allow communication between them, this keeps traffic from one VLAN from combining with that of another, preserving isolation.

Only managed switches, which provide the required control, can be used to configure VLANs. In order to identify which devices are part of each virtual network segment, administrators allocate particular switch ports to specific VLANs.

Types of VLAN Ports: Access vs Trunk

A switch's VLAN ports can be classified as either trunk ports or access ports. Usually used to connect end devices such as PCs or printers, a access port is allocated to a single VLAN. It transmits and receives VLAN-specific untagged traffic.

A trunk port, on the other hand, is perfect for links between switches or between a switch and a router because it can transport traffic for multiple VLANs simultaneously.

Trunk ports employ VLAN tagging, which adds identifiers to packets and is based on the IEEE 802.1Q standard. For instance, to guarantee appropriate traffic routing, two switches with different VLANs can be connected via a trunk port.

VLAN Configuration Example (Simplified Setup)

The network is logically divided into three VLANs—HR, Sales, and IT—and a single switch in a basic network configuration to enhance security and performance.

For instance, VLAN 10 (HR) could be assigned to ports 1–4, VLAN 20 (Sales) to ports 5–8, and VLAN 30 (IT) to ports 9–12. Using a switch's CLI or GUI, you can configure VLANs by assigning ports and turning on VLAN tagging.

The VLAN structure must be planned and documented in order to guarantee effective management and prevent possible conflicts, particularly as the network grows or evolves over time.

Benefits of Using VLANs in a Network

Advantages of Networking with VLANs The first advantage that VLANs provide to networks is better security. Sensitive information is kept safe by limiting unwanted access between groups by dividing various departments or functions into distinct VLANs.

By restricting broadcast traffic to devices that are part of the same VLAN, VLANs also aid in reducing congestion and improving performance. VLANs also simplify diagnostics by isolating problems to particular VLANs, which makes network troubleshooting and management easier.

 Last but not least, VLANs are perfect for growing networks because they are highly scalable, enabling network expansion without the need for additional hardware or rewiring.
