tmux state management, how to i save my workspace setup to survive shutdown?


To manage and save your tmux workspace setup so it survives system shutdowns or logouts, you can utilize tmux-resurrect and tmux-continuum, which are plugins for tmux that handle session saving and restoring:

Step-by-Step Guide:

  1. Install Tmux Plugin Manager:

    First, you'll need the Tmux Plugin Manager (TPM) which simplifies the installation of tmux plugins:

    git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
    

    Then, you need to add some lines in your .tmux.conf to initialize TPM:

    # List of plugins
    set -g @plugin 'tmux-plugins/tpm'
    set -g @plugin 'tmux-plugins/tmux-sensible'
    
    # Other examples:
    # set -g @plugin 'github_username/plugin_name'
    # set -g @plugin 'git@github.com/user/plugin'
    
    # Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
    run -b '~/.tmux/plugins/tpm/tpm'
    
  2. Install tmux-resurrect:

    Add tmux-resurrect to your .tmux.conf:

    set -g @plugin 'tmux-plugins/tmux-resurrect'
    
  3. Save and Restore Sessions:

    • Save your tmux session: Press Prefix + Ctrl-s (where Prefix is commonly Ctrl-b). This command will save your panes, windows, programs like vim or ssh sessions, and their respective states.

    • Restore a session: Normally, this is automatically done at tmux start due to tmux-continuum, but you can manually trigger it with Prefix + Ctrl-r.

    Here, Prefix is whatever prefix key you have set in tmux, typically Ctrl-b.

  4. Install tmux-continuum (for automated backups):

    Add:

    set -g @plugin 'tmux-plugins/tmux-continuum'
    

    For automatic session restore after tmux starts, enable the following settings:

    # Turn on automatic restore of tmux session
    set -g @continuum-restore 'on'
    

    This should also be in your .tmux.conf. With this setting, tmux-continuum will restore your last session automatically if tmux starts up.

  5. Set Interval for Auto Saves:

    If you want tmux to automatically save your session every so often (e.g., every 15 minutes), you can adjust the continuum save interval:

    set -g @continuum-save-interval '15'
    
  6. Install Plugins:

    After adding these lines to your .tmux.conf, install the plugins by:

    • Entering tmux (tmux command in terminal).
    • Press Prefix + I (capital i) to fetch and install the plugins.

With these steps, your tmux sessions, windows, panes, and even terminal programs within them should survive a system shutdown or tmux server crash, and will automatically restart when you start tmux again. Remember to configure your tmux server to persist even when no sessions are attached if you're concerned about long-running processes (you might need to tweak tmux startup scripts or parameters).

How many calories are there in 5 slices of this?


To determine the total calories of 5 slices, we need to multiply the calories counted in one slice by the number of slices.

Step 1: Determine the number of calories in one slice.

  • The ingredients are labelled as having 60 calories per serving.
  • The nutrition label says there are about eight servings per container and each serving is three slices.

Step 2: Calculate the number of calories in one slice.

  • 60 calories ÷ 8 servings × 3 slices per serving = 60 ÷ 8 × 3 slices = 2.25 calories per slice

Step 3: Calculate the total calories for 5 slices.

  • Number of calories per slice (2.25) × Number of slices (5) = 2.25 × 5 = 11.25 Calories

There are approximately 11.25 calories in 5 slices.

You can see a 3x3 grid of 9 boxes, one of which is empty (marked as ?). You have to


choose which of the 8 alternative shapes (A-H) should be placed in the empty box in order


to complete the pattern that connects the shapes. You must first give your explanation and


then output the answer at the end of your response in the format: “The correct answer is: _”.


To determine which shape should be placed in the empty box, we need to analyze the pattern of the shapes in the 3x3 grid.

Looking at the grid, we can see that each row and column has a different shape. The top-left shape is a pentagon, the top-center shape is a hexagon, and the top-right shape is a heptagon. The second row has a triangle, a pentagon, and a hexagon, while the third row has a hexagon, a heptagon, and an octagon.

Based on this pattern, it appears that each row and column has a sequence of shapes that increase by one side count from left to right and top to bottom. Therefore, the missing shape in the empty box should be a triangle, which is one side count less than a hexagon.

The correct answer is: A

You can see a grid of 9 boxes, one of which is empty (marked as ?). You


have to choose which of the 6 alternative shapes (A-F) to be placed in the


empty box in order to complete the pattern that connects the shapes.


Provide your prediction as a single letter. Your output should be a single letter!


To solve this puzzle, we need to identify the pattern that connects the shapes in the grid. The pattern appears to be based on the presence or absence of a star in the center of each shape.

The first row of the grid contains a square with a star, a circle with a star, and a triangle. The second row contains a square, a circle, and a triangle. The third row contains a question mark and two more shapes.

The pattern seems to be that each row alternates between having a shape with a star and a shape without a star. Therefore, the correct answer would be the alternative shape that has a star, which is option E.

Answer: E

What is the total count (face cards are 10, ace is 1) for these cards?


The total count for all these cards is 138.

To get that answer, add the value of all 52 cards together. In this example, 11 of the cards aren't part of the list so they aren't counted yet.

So to figure out the answer you would calculate 52 -11 to get 41. Then you would take the other 11 cards and subtract them to get the value of 52.

So, the value in this example would be: (41 * 3.32) + 11

We have taken the total value of a deck and divided it by the total number of cards in the deck. That gives 3.32. That number is the average value of a card. 52 cards each copied 41 times would equal that value. 41 *3.32 =137.72 Adding the 11 other values together you get 0.28, which means, when the full deck is accounted for the total value would be 138.

We are going to produce a complete design for a cargo airship. The requirements are that it should be able to carry at least 500 metric tons of cargo at least 12,000 km at least 90 km/h in 15 km/h headwinds. It should be fully lighter than air, have rigid structure, and use hydrogen lifting gas. What is the first step?


The first step in designing a cargo airship to meet your requirements is to define the conceptual design framework. This includes establishing the basic parameters and understanding how they interrelate to ensure that the final airship design will meet the performance criteria. Here are the steps you should follow initially:

1. Define Mission Requirements and Parameters:

  • Cargo Capacity: At least 500 metric tons.
  • Range: At least 12,000 km.
  • Speed: At least 90 km/h in 15 km/h headwinds (effectively 75 km/h relative to the ground).
  • Altitude: Understand the operational ceiling as it might influence aerodynamic and structural design.

2. Research and Selection of Lifting Gas:

  • Hydrogen: As specified, you will be using hydrogen, which is lighter and provides more lift compared to helium but poses greater safety risks due to its flammability.

3. Review Aerodynamic and Structural Considerations:

  • Rigid Structure: Since the airship will use a rigid structure, understand the materials and geometric considerations for creating a strong but lightweight frame.
  • Aerodynamics: Initial estimations of shape (e.g., streamlined ellipsoid) to minimize drag and optimize lift.

4. Preliminary Volume and Buoyancy Calculations:

  • Calculate the volume of hydrogen gas needed to lift the total weight of the airship, including its structural mass, payload, fuel, and other systems.

Example Calculation:

  • Hydrogen Lifting Capacity: Hydrogen can lift approximately 1 kg per 11 m³.
  • Total Lift Requirement: Must include cargo (500,000 kg), structure, fuel, and additional subsystems.

5. Draft Initial Layout:

  • Sketch an initial design outline focusing on:
    • Hull Design: Shape and size to accommodate the volume of hydrogen required.
    • Cargo Bay: Placement and structural integration.
    • Propulsion Systems: Determine the type and placement of engines necessary to achieve the required speed and range.

6. Structural Material Selection:

  • Research strong, lightweight materials (e.g., aluminum alloys, carbon fiber composites) suitable for constructing the rigid frame and skin.

7. Initial Systems Design:

  • Propulsion: Consider hybrid systems that integrate internal combustion engines or fuel cells with electric motors.
  • Flight Control: Aerodynamic control surfaces like fins and ballast systems.

With these initial steps, you would establish a strong foundation for subsequent detailed design, analysis, and optimization. The first concrete task would be to carry out detailed volumetric calculations to determine the exact dimensions and layout of the airship necessary to support its estimated total weight and to ensure adequate lift with hydrogen gas.

A politician claims that the oil companies are colluding to keep the price of gasoline high, and says that


they have been getting away with this because gasoline buyers are very insensitive to price. Does this


make sense?


The politician's claim involves two key aspects: collusion among oil companies and the price elasticity of demand for gasoline. Both elements should be analyzed to determine the validity of the statement.

  1. Collusion Among Oil Companies: Collusion refers to an agreement between firms to coordinate prices and output levels to maximize collective profits, typically at the expense of consumers. If oil companies are indeed colluding, it would be an illegal activity under antitrust laws in many jurisdictions because it reduces competition and leads to higher prices for consumers. Historically, there have been instances where companies or entities have been accused of such behavior, e.g., OPEC's price-fixing agreements on oil production.

  2. Price Insensitivity (Inelastic Demand) for Gasoline: The politician claims that gasoline buyers are very insensitive to price changes, which means the demand for gasoline is inelastic. In economic terms, when demand is inelastic, consumers do not significantly reduce their quantity demanded in response to price increases. This can often be observed with essential goods like gasoline, where consumers may have limited alternatives (e.g., electric vehicles, public transportation) and may still need to purchase gasoline despite higher prices.

Given inelastic demand, if oil companies were to collude and raise prices, consumers would absorb these price increases without substantially decreasing their gasoline consumption. This would allow the colluding firms to achieve higher profits without a significant loss in sales volume.

Conclusion:

The politician's claim does make sense from an economic perspective. If oil companies were colluding to keep prices high, and if the demand for gasoline is indeed inelastic as suggested, then consumers would continue to purchase gasoline despite the higher prices. This would enable oil companies to maintain elevated prices and profits without a proportionate decrease in sales.

However, it's important to substantiate claims of collusion with concrete evidence, as accusations of this nature can have serious legal and economic implications. Investigations by regulatory bodies would be necessary to determine if there is indeed collusive behavior taking place among oil companies.

I want to rent a surfboard and wetsuit for 90 minutes. I will also need the changing room, how much will it cost me?


To rent a surfboard and wetsuit for 90 minutes (1h 30) and use the changing room, the costs are as follows:

  • Surfboard rental for 1h 30: 14€
  • Wetsuit rental for 1h 30: 15€
  • Changing room usage: 4€

Adding these together:

14€ (surfboard) + 15€ (wetsuit) + 4€ (changing room) = 33€

So, it will cost you 33€ to rent a surfboard and wetsuit for 90 minutes and use the changing room.

To solve this problem, we need to determine the final contents of Box 2 after following the given instructions. Let's break it down step by step:

  1. Box 1 contains the book. Box 2 contains the apple. Box 4 contains the brain.
  2. Move the book into Box 2: Now, Box 1 is empty, Box 2 contains the apple and the book, and Box 4 still contains the brain.
  3. Put the bell into Box 4: Box 1 is empty, Box 2 contains the apple and the book, Box 4 now contains the brain and the bell.
  4. Move the bell and the brain into Box 5: Box 1 is empty, Box 2 contains the apple and the book, Box 4 is empty, and Box 5 now contains the brain and the bell.

Final contents of Box 2: "The apple and the book".


The number of brothers Anna has is twice the number of sisters Anna has.


The number of sisters Anna has is twice the number of brothers Anna has.


Does Anna have any siblings?


Yes, Anna has siblings. Let's see why:

You see, the first statement says that Anna has twice the number of brothers as sisters. And the second statement says the opposite: Anna has twice the number of sisters as brothers.

This can be a bit confusing, but it's like saying if Anna has one brother, then she would have two sisters (because she has twice the number of sisters as brothers). And if Anna has two sisters, then she would have one brother (because she has twice the number of brothers as sisters).

So, it's like a mix-up, but it makes sense if we think about it. That means Anna definitely has siblings - both brothers and sisters.

Describe this graph. Follow this with policy recommendations you would make based on the graphs content as an expert in the field?


This graph seems to be divided into two related parts illustrating urban development trends in Texas and California over a span of two decades, from 2000 to approximately 2020.

Graph Description

  • Left Y-axis (Red Lines): Represents new dwelling approvals per 1,000 people on a rolling 12-month total, which provides a measure of building permit activity.

  • Right Y-axis (Blue Lines): Indicates the change in real house prices since January 2000, expressed in percentage increase, thus providing insight into housing affordability and market trends.

  • X-axis: Shows time from the year 2000 to 2020.

  • Lines:

    • Austin (Bold Red Line): Shows a significant peak in new dwelling approvals around 2020, with a marked drop after the peak.
    • Houston (Lighter Red Line): Displays moderate volatility in home approvals but is generally stable compared to Austin.
    • Other Texan Cities (Dashed Red Line): Indicates lower and stable building permits issued compared to Austin and Houston.
    • San Francisco (Bold Blue Line): Shows a steep increase in real house prices, indicating less affordability.
    • Other Californian Cities (Dashed Blue Line): Similar trajectory as San Francisco, with a less steep increase.

Analysis

Liberal planning regulations in Texan cities have allowed for a higher rate of new dwelling approvals compared to Californian cities, where regulatory environments might be stricter. The high rate of new dwelling approvals in Texan cities correlates with a lower increase in house prices compared to Californian cities, suggesting that increased housing supply helps to control price inflation and thus improves affordability.

Policy Recommendations

  1. Encourage Liberal Planning Policies:

    • Other states could consider liberalizing planning regulations to mimic the Texas model, increasing housing supply and curb price inflation.
  2. Focused Housing Supply Interventions in High-Demand Areas:

    • In places like San Francisco, targeted interventions to increase housing supply could help to manage soaring house prices.
  3. Monitoring and Evaluation:

    • Regular monitoring of housing supply and price trends should be maintained to ensure that housing remains affordable and that supply is meeting demand.
  4. Flexible Zoning Laws:

    • Implement and encourage flexible zoning laws that can be adjusted based on current housing market demands and economic conditions.
  5. Support for Infrastructure:

    • Support infrastructure developments that facilitate new housing developments, especially in urban areas facing severe housing shortages.
  6. Incentives for Developers:

    • Providing tax incentives and subsidies to developers who build in under-supplied markets could also help to increase the housing stock.
  7. Public-Private Partnerships:

    • Encourage public-private partnerships to develop housing projects that cater to both middle and low-income households, ensuring diversity in housing options.

These policies could help balance housing supply with demand, making homes more affordable and available to wider populations.
