Should I install fiberglass batts underneath my existing blown fiberglass?

I have loose fill fiberglass insulation in my attic (picture below). I was thinking about upgrading the insulation because, from what I’ve read, this is one of the least effective insulation types.

I was thinking about buying pink fiberglass rolls, clearing the loose fill out of the joist bays, putting the rolls down, then putting the loose fill back over top.

1) Is that a good strategy or should I be doing something else or using a different type of insulation?

2) If I buy the rolls, should I buy faced with a vapor barrier, or unfaced? The loose fill currently has no vapor barrier. It just sits on top of the drywall.

3) Is the cost of doing this really worth the difference in your energy bill?

How to get steam to properly install and actually open steam?

So I am VERY new to ubuntu and linux and kinda scrapping by as i’ve only been a PC gamer since december of last year. I used steam on my little garbage Lenovo using Windows 10, but after getting my I5 HP i had to run Ubuntu because the hard reset caused windows to corrupt on login. While trying to get steam on, i used Ubuntu Software AND the Terminal yet when i find the desktop/applications icon, NOTHING happens. it doesnt load up, it doesnt prompt me, literally all it did was after installation it updated. Can someone please help a noob out and let me know what I can do to get it to run? Thank you.

How can I automate Chocolatey install from a private Azure DevOps hosted feed?

I’ve got a Chocolatey package hosted in a private Azure Devops feed. The feed requires authentication. I’m trying to run this from a PowerShell script in a build task.

choco install typewriter --source="https://o365x.pkgs.visualstudio.com/_packaging/Graph/nuget/v3/index.json" --yes --force --password=PAT

I observe that it attempts basic auth. Alternate credentials are disabled for my org. I tried to use a personal access token as the password (no username) and it doesn’t work. Is there a way to do this?

Magento does not install my module

I have a very weird situation where my Magento Module is not getting installed, but its getting registered.

This is my config.xml:



    
        
            0.2.0
        
    
    
        
            
                Example_Module_Helper
            
        
        
            
                
                    Example_Module
                
                
                    core_setup
                
            
            
                
                    core_write
                
            
            
                
                    core_read
                
            
        
    
 

Any I have the following subdirectory structure:

Example /
- Module /
-- data / example_module_setup / data-install-0.1.0.php 
-- data / example_module_setup / data-upgrade-0.1.0-0.2.0.php
-- etc / config.xml
-- sql / example_module_setup / install-0.1.0.php

However, the module does not get registered in core_resource. I’ve cleared var/cache before reloading the frontend.

What is wrong here?

Ubuntu 18.04.1 for a Hyper-V VM fails to install the UEFI boot section

I am creating a Gen2 Hyper-V virtual machine, on Windows 10 Pro (x64). I have created other Windows and Ubuntu based VMs successfully on this machine. Secure Boot is disabled.

Installation of Ubuntu Server 18.04.1 using the ISO file proceeds as usual, and appears to complete successfully.

Upon reboot, the VM fails to find any bootable options:

No x64-based UEFI boot loader was found

It appears as though the EFI partition is allocated, but GRUB is not properly installed.

Android install/uninstall log

I am looking for an app that will display a log of all app installations and uninstallations. Each log entry should display the date and optionally also the time of installation or uninstallation along with the app name and app icon of the corresponding app.

The user should be able to view the list in chronological, reverse chronological, or alphabetical order.

One of the reasons this app would be useful is that most devices have limited device memories, causing the user to often have to uninstall an app our set of apps to make room for other ones the user wants to install. Unless the uninstall app is a paid app, the user might lose track of it despite it being useful, and might forget the app name making it difficult or impossible to find the app again for downloading from the play store.

The log should also allow the user to view each last install or uninstall of any given app as part of two separate uninstall and install lists (thus allowing the user to quickly find the names of apps that were deleted directly from the uninstall list).

Does any such Android app exist?

Thanks.

Black ops 2 dlcs download and install but doesn’t show up

I am having trouble with my Black Ops 2 map packs that an in-game friend of mine has shared with me. Once that finished installing I went to play them.

Unfortunately, they are no where to be found in the game on Multiplayer or Zombies which is really pissing me off. This only happens with Black Ops 2 even if I purchase the DLCs. I don’t know what to do and I need help.

Partial Maven Clean Install after Git Pull

I had searched for a solution to mvn clean install on my changed projects after a git pull. I even asked a question over at SO about the same thing. The answer I got pointed me into creating my own script to achieve what I wanted to accomplish. So I went, I saw, and I conquered the script that I wanted. However, it is probably not efficient, and could use refactoring. I am new to bash scripting and learned a bit while doing this. So enough chit-chat from me and on to the main event.

The code can also be found on GitHub
