Backspace key broken when running as root


I've installed Void Linux base image and my backspace key is broken when I am root, it types '^H' instead of erasing. Function keys also type something weird, but at least the brighness-related ones do work.

This only applies to the root shell, it all works perfectly when I login as a normal user. Probably a bashrc issue?

How to Improve Cost per Ton Through Better Concrete Crusher Machine Operation


The media in this post is not displayed to visitors. To view it, please go to the original post.

In the demanding world of aggregate production and demolition recycling, the margin between profitability and loss is often measured in cents per ton. While much attention is lavished on the initial capital expenditure of acquiring a concrete crusher for sale, the true arbiter of financial success lies in the daily operational choices made on the plant floor. The difference between a well-tuned machine and one that is merely functioning is a chasm of wasted energy, accelerated wear, and subpar product quality that cumulatively erodes the bottom line.

This is not a narrative about purchasing newer or larger equipment; it is a granular exploration of optimizing the machine you already possess. From the judicious management of feed material to the meticulous calibration of closed-side settings, every variable exerts a tangible influence on the cost per ton metric. By adopting a philosophy of continuous improvement and operational vigilance, producers can unlock significant savings, enhance throughput, and extend the service life of their crushing assets. This article delves into the pivotal operational strategies that can transform a crusher from a cost center into a profit engine.

Feed Management and Its Cascading Effects

Mastering the Art of Consistent Feeding


It is an axiom of crushing that a crusher performs best when it is choke-fed, meaning the crushing chamber is consistently full of material. This ensures continuous rock-on-rock crushing and maximizes the machine's efficiency. Conversely, a sporadic or underfed crusher experiences wide fluctuations in power draw and excessive component strain. Inconsistency is the nemesis of both efficiency and longevity, leading to erratic product gradation and premature failure of manganese liners.

Proper feed distribution is equally critical. Allowing material to segregate or funnel solely into one side of the chamber induces uneven wear and reduces the crusher's overall capacity. Furthermore, an excess of fines entering the chamber can impede throughput and create excessive dust. Pre-screening the feed to remove deleterious fines not only protects the crusher from packing but also allows it to focus its energy on reducing larger, more valuable aggregates. This pre-conditioning of the feed stream is a foundational step in cost reduction.

Optimizing for Ideal Particle Size Distribution


Understanding the relationship between feed size and crusher performance is paramount. Feeding material that is too large will stall the crusher; feeding material that is too small wastes capacity and increases the specific energy consumption per ton. Achieving a balanced feed gradation that aligns with the mobile impact crusher's design parameters ensures the machine operates within its optimal power band. This synergy between feed and machine capability is the cornerstone of efficient comminution.

While it may seem counterintuitive to add a secondary screening stage, the economic benefits are irrefutable. By removing material that is already at target size, you prevent it from taking up valuable capacity in the crushing chamber. This increases the overall plant throughput and reduces the wear burden on the crusher's wear parts. The energy saved by not re-crushing fines translates directly into lower cost per ton, demonstrating that sometimes, the path to efficiency lies in doing less.

Calibration, Maintenance, and Wear Management

The Criticality of Closed-Side Setting (CSS)


The closed-side setting (CSS) is the most critical operational parameter of a cone or jaw crusher. This setting dictates the maximum particle size of the product. A CSS that is too tight will lead to over-crushing, excessive liner wear, and high power consumption. Conversely, a CSS that is too open will produce a coarser product, potentially failing to meet specifications and requiring recirculation, which doubles the processing cost. Regularly monitoring and adjusting the CSS to align with production goals is a non-negotiable practice for cost control.

Modern crushers are often equipped with advanced automation systems that provide real-time data on power draw, crusher load, and CSS. Rather than relying on reactive maintenance, operators should cultivate a proactive stance, using this data to predict when adjustments are necessary. An incremental tightening of the CSS as liners wear can maintain product quality and extend liner life, thereby smoothing the cost curve over the liner's lifecycle. This is the essence of smart, data-driven operation.

Implementing a Rigorous Maintenance Cadence


Preventative maintenance is not an expense; it is an investment in uptime and profitability. The cost of an unplanned shutdown due to a snapped eccentric bushing or a failed bearing far outweighs the cost of scheduled lubrication and inspections. A disciplined adherence to the manufacturer's recommended maintenance schedule is the most effective deterrent against catastrophic failures and the associated lost production.

Wear parts, such as manganese liners, are designed to consume themselves to protect the rest of the machine. However, allowing them to wear to the point of failure is a false economy. Running a crusher with a worn liner that has lost its profile leads to a drop in throughput and an increase in power consumption. Changing liners at the optimal time—when they are worn out but before they cause secondary damage—ensures consistent performance and minimizes the total cost of ownership. It is far more economical to change a liner than to rebuild a mantle.

Process Integration and Material Flow

Synchronizing the Downstream Conveying System


The crusher does not operate in isolation; it is an integral node in a complex material flow network. A crusher that is forced to wait for a conveyor to clear or for a stockpile to be managed is a crusher that is generating zero revenue. Optimizing the entire plant flow, from the primary feeder to the final product stockpile, ensures that the bottleneck is always the crusher itself, not the ancillary equipment. This systems-thinking approach is vital for maximizing overall plant efficiency.

Material blockages and excessive recirculation loads are indicators of a system out of balance. Analyzing the circuit to identify pinch points and adjusting conveyor speeds or screen media can alleviate these bottlenecks. Reducing the recirculating load allows the crusher to focus its energy on new material, significantly improving the cost per ton metric. This continuous optimization of the process flow is the hallmark of a world-class operation.

Prioritizing Operator Training and Autonomy


A crusher is only as good as the person at the controls. Investing in comprehensive operator training that covers not just the controls but also the underlying principles of comminution pays dividends in improved performance. An empowered operator who understands the "why" behind the parameters is far more effective at making real-time decisions that prevent costly errors and optimize production. They are the final and most critical component of the efficiency equation.

Ultimately, improving cost per ton is not a one-time project but an ongoing journey. Fostering a workplace culture where operators are encouraged to share observations and suggest improvements can lead to incremental gains that compound over time. By valuing the human element as much as the mechanical one, companies can build resilient operations that consistently outperform their peers in the challenging landscape of aggregate production.

I'm feeling pretty justified in sticking with Wacom. I only replaced my first tablet because it had a 4:3 aspect ratio and a serial port. (I could've lived with the latter, but the aspect ratio was making things skewed on a modern display.)

need help for powersaving a software raid


Hello there
I want to reduce the consumption of my server and so, to reduce access to hard drives

But I suspect mdadm to access the drives frequently and wake them up.

Because even when the drives are not mounted, they wake up frequently and I can't find the reason.

Because the are not mounted, it's not due to a process.

I've temporarily disabled smartd so it's not that.

remains the software raid, who can potentially do regular checks, if that's the case how to fix it?
?

ps: I know spin down/up isn't good

in reply to Salcie

You can try and figure out what's accessing the array:

fatrace | grep /mnt/mountpoint/

This will show you the process, type of access (read, write, open, etc), and path. If you don't see anything right away just leave it running for a bit.

Fedora/KDE keyboard woes


Hello people,

I have been experiencing some trouble with my keyboard lately since moving from Windows to Linux and have yet to find a proper solution. I'm running Fedora 44 (KDE Plasma Desktop), specifically:

Operating System: Fedora Linux 44
KDE Plasma Version: 6.7.1
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 7.0.13-200.fc44.x86_64 (64-bit)
Graphics Platform: Wayland

The keyboard is a NuPhy Halo75 (ANSI-US layout). It has a toggle to switch between Windows and Mac mode/layout and media keys on the function row; I want the function keys to be function keys by default and media keys when pressing Fn. On Windows, I was using the "US International" layout (primarily for Ä/Ö/Ü on Alt+Q/Y/P and € on Alt+5).

Now, sadly, on Linux, with the keyboard toggle set to Windows and either the "English (US, intl., with dead keys)" or "English (US, intl., AltGr. Unicode combining)" layout enabled, I can type my precious umlauts etc. perfectly fine, but the function keys always act like media keys, no matter what else I press, and I have not found any way to change that behavior. With the toggle set to Mac, the function keys work fine (as do the media keys with Fn), but I can no longer type umlauts (and what even am I without my umlauts). I enabled the "Alt is swapped with Win" keyboard option, since those are swapped on the Mac layout. From the keyboard preview, the key presses seem to be mapped correctly (left and right alt show up as "Meta L/Alt L" and "Meta R/Alt R", respectively, the Windows key shows up as "Super L").

I'm probably just missing some option or something, but I've looked everywhere I could think of (and, considering I am quite new to Linux/KDE, that isn't too many places) without luck. My web searches didn't really turn up anything useful either. So, if anyone has an idea or knows where to look and what to change, that would be highly appreciated! I hope my description of what I'm looking for is understandable.

I apologize for the somewhat long-ish post, but if you read this far, thank you 😀

Evaluating Investment Risks in Continuous Pyrolysis Projects


The media in this post is not displayed to visitors. To view it, please go to the original post.

Continuous pyrolysis has gained increasing attention as an industrial solution for converting waste materials and biomass into valuable products such as pyrolysis oil, biochar, syngas, and recovered carbon materials. Compared with batch systems, continuous facilities offer higher throughput, greater automation, and improved production consistency. However, these advantages are accompanied by higher capital requirements and greater operational complexity.

A successful investment depends on evaluating risks across technical, financial, regulatory, and commercial dimensions rather than focusing solely on equipment specifications. Thorough due diligence helps investors identify potential challenges before significant capital is committed.

Although many continuous pyrolysis systems recover process gas for internal heating, external fuel and electricity remain significant operating expenses.

Energy cost analysis should consider:

  • Local fuel prices
  • Electricity tariffs
  • Heat recovery efficiency
  • Utility reliability

Improving thermal efficiency directly enhances project profitability.

Maintenance Expenditure


Continuous operation places sustained mechanical stress on reactors, conveyors, bearings, and sealing systems.

Preventive maintenance planning and spare parts inventory should be incorporated into long-term financial models rather than treated as occasional expenses.

Evaluating Market Demand

Product Sales Stability


Project economics depend heavily on the ability to sell output products at sustainable prices.

Potential revenue sources may include:

  • Pyrolysis oil
  • Biochar
  • Recovered carbon products
  • Syngas utilization
  • Recovered steel for tire processing projects
  • Carbon credit opportunities where applicable

Diversifying revenue streams reduces dependence on any single product market.

Price Volatility


Market prices for recovered products may fluctuate due to changes in crude oil prices, agricultural demand, environmental policy, or regional supply conditions.

Sensitivity analysis helps investors understand how price changes may affect project profitability.

Regulatory and Environmental Risk

Permitting Requirements


Continuous pyrolysis facilities often require multiple regulatory approvals before construction and operation.

These may include:

  • Environmental impact assessment approval
  • Air emission permits
  • Waste management authorization
  • Fire safety approval
  • Industrial operating licenses

Project schedules should incorporate sufficient time for regulatory review.

Compliance Costs


Environmental regulations continue to evolve, particularly regarding emissions and waste management.

Investors should anticipate future expenditures related to equipment upgrades, monitoring systems, and reporting requirements.

Construction and Commissioning Risk

Project Execution Challenges


Construction delays may result from:

  • Equipment delivery issues
  • Contractor coordination problems
  • Utility connection delays
  • Permit revisions
  • Supply chain disruptions

Comprehensive project management reduces schedule uncertainty and minimizes cost overruns.

Performance Verification


Commissioning should verify that the facility achieves its designed processing capacity, product quality, energy efficiency, and environmental performance before commercial operation begins.

Independent performance testing provides valuable assurance for investors.

Operational and Management Risk

Workforce Capability


Continuous pyrolysis facilities require experienced operators capable of maintaining stable process conditions and responding to abnormal situations.

Training programs should emphasize:

  • Process control
  • Equipment maintenance
  • Safety management
  • Quality assurance
  • Emergency procedures

Skilled personnel contribute significantly to long-term operational reliability.

Digital Monitoring


Modern facilities increasingly utilize automated monitoring platforms to collect production data, identify equipment degradation, and optimize operating parameters.

Data-driven management improves decision-making while reducing unexpected operational disruptions.

Building a Balanced Investment Strategy


Continuous pyrolysis projects offer considerable opportunities for resource recovery, circular economy development, and sustainable industrial growth. However, their long-term success depends on balancing technological capability with commercial viability, regulatory compliance, and operational excellence.

Investors who conduct comprehensive risk assessments across feedstock supply, technology maturity, financial planning, market demand, environmental compliance, and operational management are better positioned to achieve stable returns while minimizing uncertainty. A disciplined evaluation process transforms investment decisions from speculative ventures into strategically managed industrial opportunities.

Risk Mitigation Strategies for Safety Hazards in Plastic Pyrolysis Projects


Understanding the Intrinsic Risk Profile of Plastic Pyrolysis
The media in this post is not displayed to visitors. To view it, please go to the original post.

Plastic pyrolysis systems operate through thermal decomposition of hydrocarbon-based polymers in an oxygen-deficient environment. While this process enables valuable resource recovery, it inherently involves elevated operational risks due to high temperatures, combustible gases, pressurized systems, and complex chemical intermediates.

Unlike conventional mechanical recycling, plastic pyrolysis introduces a multi-phase hazard environment where thermal, chemical, and mechanical risks interact. Effective safety design is therefore not an auxiliary consideration but a core engineering requirement that defines operational viability.

Feedstock-Related Safety Hazards

Contamination and Reactive Impurities


The safety profile of a plastic pyrolysis machine is strongly influenced by feedstock composition. Waste plastic streams may contain:

  • Chlorinated polymers
  • Residual solvents
  • Metal contaminants
  • Moisture content variability
  • Mixed polymer fractions

Certain contaminants can generate corrosive gases or unstable reaction byproducts during thermal processing, increasing operational risk.

Feedstock Pre-Treatment Requirements


Proper pre-processing significantly reduces hazard potential. Standard safety-oriented measures include:

  • Magnetic separation of metals
  • Shredding and homogenization
  • Moisture reduction systems
  • Chlorine content screening

Failure to control feedstock quality can lead to unstable reactor conditions and unpredictable emissions.
Continuous Plastic Pyrolysis Plant

Thermal Runaway and Reactor Safety Control

Temperature Instability Risks


Plastic pyrolysis reactor operates at elevated temperatures typically ranging from 350°C to 600°C. Within this range, minor deviations in heat input or feedstock composition can trigger thermal instability.

Potential consequences include:

  • Accelerated gas generation
  • Pressure surges
  • Incomplete cracking reactions
  • Localized overheating zones


Multi-Layer Temperature Control Systems


Modern safety engineering relies on redundant thermal management strategies such as:

  • Distributed temperature sensors
  • Automated feedback control loops
  • Emergency cooling circuits
  • Independent safety shutdown systems

These mechanisms ensure that deviations are detected and corrected before reaching critical thresholds.

Pressure Accumulation and Gas Handling Risks

Non-Condensable Gas Behavior


Plastic pyrolysis generates significant volumes of non-condensable gases, including light hydrocarbons and hydrogen-rich mixtures. If not properly managed, these gases can accumulate within the system.

Risk scenarios include:

  • Overpressure in reactor vessels
  • Pipeline rupture
  • Flash ignition events
  • Backflow incidents


Pressure Relief Engineering


Effective mitigation requires integrated pressure control infrastructure:

  • Pressure relief valves
  • Gas buffer tanks
  • Flare or combustion units
  • Automated venting systems

These components ensure that abnormal pressure conditions are safely discharged or neutralized.

Flammability and Explosion Risk Management

Hydrocarbon Vapor Sensitivity


Pyrolysis oil and intermediate vapors are highly flammable under specific temperature and concentration conditions. This creates a dual-phase explosion risk involving both gas-phase and liquid-phase hydrocarbons.

Explosion Prevention Systems


Key preventive measures include:

  • Inert gas blanketing (nitrogen systems)
  • Oxygen monitoring and exclusion
  • Anti-static grounding systems
  • Flame arrestors in gas lines

These systems collectively reduce ignition probability and propagation potential.

Condensation and Liquid Handling Safety

Volatile Hydrocarbon Management


Condensation systems recover liquid hydrocarbons from pyrolysis vapors. However, these liquids may contain unstable fractions with low flash points.

Safety risks include:

  • Vapor leakage
  • Storage tank overpressure
  • Liquid volatilization
  • Spill-related ignition hazards


Safe Storage Infrastructure


Proper engineering design requires:

  • Sealed storage tanks with pressure control
  • Temperature-regulated storage zones
  • Secondary containment systems
  • Vapor recovery units

These features ensure safe handling of recovered oil products.

Solid Residue Handling Risks

Char Dust and Particulate Hazards


Solid residues from plastic pyrolysis often include fine carbonaceous particles that may present:

  • Dust explosion risks
  • Respiratory hazards
  • Static charge accumulation
  • Fire propagation potential


Dust Control Engineering


Effective mitigation includes:

  • Enclosed material handling systems
  • Dust extraction and filtration units
  • Humidity control measures
  • Anti-static material transfer systems

Proper design minimizes both occupational and process safety risks.

Mechanical System Safety Considerations

Equipment Wear and Failure Modes


Continuous operation of shredders, conveyors, and feeding systems introduces mechanical risks such as:

  • Bearing failure
  • Belt misalignment
  • Motor overheating
  • Structural fatigue

These failures can indirectly trigger process instability if feedstock flow is disrupted.

Predictive Maintenance Systems


Modern facilities reduce mechanical risk through:

  • Vibration monitoring systems
  • Infrared temperature scanning
  • Predictive maintenance algorithms
  • Scheduled component replacement

Early detection of wear conditions prevents cascading failures.

Fire Protection and Emergency Response Design

Multi-Stage Fire Suppression Systems


Given the combustible nature of inputs and outputs, fire protection must be multi-layered:

  • Automatic fire detection sensors
  • Foam or dry chemical suppression systems
  • Water spray cooling networks
  • Zoned isolation capabilities


Emergency Shutdown Protocols


A critical safety requirement is the ability to rapidly isolate and shut down the entire process chain. Emergency systems typically include:

  • Automatic feedstock cutoff
  • Reactor isolation valves
  • Gas system bypass routing
  • Controlled cooling sequences

These systems prevent escalation during abnormal conditions.

Control System Reliability and Cyber-Physical Safety

Automation Dependency Risks


Plastic pyrolysis plants rely heavily on automated control systems. Failure in these systems can lead to uncontrolled thermal or pressure conditions.

Redundant Control Architecture


To enhance reliability, safety-critical systems are often designed with:

  • Dual-redundant PLC systems
  • Independent safety instrumented systems (SIS)
  • Fail-safe default states
  • Real-time diagnostic monitoring

This layered architecture ensures operational continuity and safe shutdown capability.

Human Factors and Operational Discipline

Operator Training Requirements


Human error remains a significant contributor to industrial accidents. Comprehensive training programs must cover:

  • Emergency response procedures
  • Equipment operation protocols
  • Hazard recognition techniques
  • Standard operating procedures compliance


Safety Culture Integration


Sustainable risk mitigation depends on embedding safety awareness into daily operations rather than treating it as a compliance obligation.

Engineering a Safer Plastic Pyrolysis Ecosystem


Plastic pyrolysis inherently involves complex thermal and chemical processes that require rigorous safety engineering. Effective hazard mitigation depends on integrated system design across feedstock management, reactor control, gas handling, liquid storage, and solid residue processing.

When properly engineered, these systems can significantly reduce operational risks while maintaining efficient resource recovery. Safety in plastic pyrolysis is not achieved through isolated safeguards but through a cohesive architecture of redundancy, monitoring, and disciplined operational control.

Desktop environments: performance vs modern look


Some DEs are focused on resource efficiency, but don't look fancy. Others are fancy, but require a fairly modern setup. I have KDE (Fedora) installed on my laptop, I love its look and options. But it is not always snappy, some little freezes occur as well, even in basic situations (opening Firefox and v2rayN simultaneously was one of the cases). The most problematic thing is almost every app taking around 2-3 secs to open its window.

Many people would just tell me to install Xfce, but I still want a fancy desktop, I believe it is something I can afford on my setup. First I thought of GNOME, but it is controversial: some sources report GNOME as well optimized even for low-end machines, other claim it is much heavier than KDE.

What it your experience with desktop environments and their performance? Perhaps you have compared various DEs within the same distro and setup? How performant GNOME actually is compared to KDE? What are the balanced options to explore?

Your burned CDs and DVDs are decaying, and the photos on them may already be gone


in reply to ☆ Yσɠƚԋσʂ ☆

Yes, the older ones of the rotating backups are still readable.

But that's not even the actual problem nowadays: CDs and DVDs were nice when their size was still relevant in comparison to usual amounts of data. The real problem behind their decay is that we are lacking a widely available, properly scaled backup solution for more than a decade. So the mean reason people have now unreadable optical data is that they stopped thinking about it a long time ago for an utter lack of options.

Well, there are 100GB and 120GB Bluray M-Discs. But yeah, the only things larger are either spinning rust (i.e. HDDs that need to be refreshed regularly to prevent bit rot) or very expensive LTO hardware and tapes.

Best way to watch a directory for changes and auto-git-commit on Arch Linux?


I need a real-time filesystem watcher that detects when any file in ~/.hermes/config/ changes, then immediately git add -A && git commit -m "auto: ..." && git push.

Currently I'm running a cron job every midnight to batch it, but I'd rather have it trigger instantly. On Arch (btw) what's the cleanest approach?

I've looked at:
- incron — old, seems barely maintained
- systemd path units — native, but feels heavyweight for one small folder
- inotifywait in a loop — simple but fragile
- entr — neat but needs something to kick off the initial watch

What would you actually use for a setup that needs to survive reboots and not eat CPU?

Greybeard dev here, just stepping by to say I would do the same, this works and does nothing weird if there is nothing to commit.

I don't know what the problem of the other crying person is, but robust IO watching should not be done in bash and whatever the fancy solution is it will not work as reliably as this.

SOLVED!: Second drive disappeared after Mint reinstall


Solution: There never was a second drive. It must have been a partition that got wiped with the install, but there's only the NVME in there. Sorry, guys. I dig around in my innards very frequently and just thought I was mounting a second drive this entire time. Hooray for backups.

reinstalled Mint and my second drive is absolutely invisible to everything. I can't mount what I can't see. I'm thinking of unplugging it and plugging it back in just because I'm out of ideas.

What could have caused a drive to become invisible after a reinstall?

Edit: Checked bios. All security disabled. Using AHCI and UEFI (tried CSM). I don't really know what these things mean, I just know things were working properly before I reinstalled mint so I'm puzzled why it could be a BIOS issue.

AI music generation has matured fast. Tools like Riffusion turn a simple text prompt into full songs, instrumentals and vocal ideas in seconds, which is great for creators who need original, royalty-free soundtracks.

The workflow is simple: describe the mood, tempo and style, then generate and refine. You can read more about the AI music generator and try it for free.

Disabling bloatware


I've discovered Akonadi, a KDE service. As far as I could understand, Akonadi provides "personal information management" and is responsible for some interaction between apps within the KDE ecosystem.
To me, it seems to be bloatware. Somebody may use the functions it provides, but I do not. It is just running in background all the time with no use.
1. How do I completely disable it forever?
2. Have you ever met something else in Linux or it's ecosystem, that appeared to be bloatware to you (and how did you disable it)?
