Life can be so beautiful, if you have a wide vision.
I stumbled upon this wonderful 3D design which is actually printable. It is an attachment to be clamped on the arm so you can play the piano.It allows you to arpeggio one octave in the major and minor scales on all of the white and black keys! A wonderful design if you’d ask me. I […]
Your Macbook or any other laptop might need some cleaning too.A laptop with dust in it cools a lot worse than when you clean it out. Only cleaning the dust out lowered the average heat pipe temperature about 4 degrees Celsius. Which is not a great but at least an improvement.
Download STL files here. To keep the strength and use less plastic I changed the fill to honeycomb and added two bars near the edges to prevent bending. Made this as part of my LACK modification for “Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table – Prusa Research” https://www.thingiverse.com/thing:2864118

Syntax Interface to the [raw] stored preference data: scutil --prefs [preference-file] Check the network reachability of a host, IP address, or a pair of local and remote IP addresses: scutil -r [-W] { nodename | address | local-address remote-address } Check for (and optionally wait for the creation of or posting of a notification to) a dynamic store key: scutil -w dynamic-store-key [-t timeout] Report and update a select group of persistent system preferences, e.g. Hostname: scutil --get pref scutil --set pref [newval] Report the current DNS configuration: scutil --dns Report the current system proxy configuration: scutil --proxy Commands for monitoring and interacting with VPN connections: scutil --nc nc-arguments Interactive command line interface to the "dynamic store" data: type help for commands (maintained by configd) scutil Key -r [-W] { nodename | address | local-address remote-address } Check the network reachability of the specified host name, IP address, or a pair of local and remote IP addresses. One or more of the following strings will be reported to standard output. Not Reachable The specified nodename/address cannot be reached using the current network configuration. Reachable The specified nodename/address can be reached using the current network configuration. Transient Connection The specified nodename/address can be reached via a transient (e.g. PPP) connection. Connection Required The specified nodename/address can be reached using the current network configuration but a connection must first be established. As an example, this status would be returned for a dialup connection that was not currently active but could handle network traffic for the target system. Connection Automatic The specified nodename/address can be reached using the current network configuration but a connection must first be established. Any traffic directed to the specified name/address will initiate the connection. Local Address The specified nodename/address is one associated with a network interface on the system. Directly Reachable Addresss Network traffic to the specified node- name/address will not go through a gateway but is routed directly to one of the interfaces on the system. The reachability can also be monitored by specifying the -W (watch) option. This will result in the current status being reported as well as the status when/if the network configuration changes. A zero exit status will be returned when the reachability status is reported correctly. A non-zero exit status will be returned if errors are detected with an error reported to standard error. -w dynamic-store-key [-t timeout] Check if the specified key exists in the "dynamic store" data main- tained by configd(8). If present, scutil will return with a zero exit status. If not present, scutil will wait for the specified time for data to be associated with or a notification to be posted using the key. A non-zero exit status will be returned if the key was not created/posted within the specified time. scutil will wait indefinitely if a timeout of 0 seconds is specified. The default timeout is 15 seconds. --get pref Retrieves the specified preference. The current value will be reported on standard output. Supported preferences include: ComputerName The user-friendly name for the system. LocalHostName The local (Bonjour) host name. HostName The name associated with hostname(1) and gethostname(3). --set pref [newval] Updates the specified preference with the new value. If the new value is not specified on the command line then it will be read from standard input. Supported preferences include: ComputerName LocalHostName HostName The --set option requires super-user access. --dns Reports the current DNS configuration. --proxy Reports the current proxy configuration. --nc nc-arguments Provides a set of commands for monitoring and interacting with VPN connections. Use --nc help for a full list of commands. |

When you run into the situation the icons are weird sorted or like in my situation having folders with items in it when closed but as soon you open the folder the items disappear, you might want to start over and reset the Launchpad. Launch Terminal, located in the /Applications/Utilities folder. In the Terminal window, […]
Everybody likes a drink one in a while, but how nice would it be to have a place where to have your drinks including glasses stored and be able to see what you have in stock. A nice way, a rack made out of pallet wood. Requirements to create this: Drill 3mm Drilling […]
So you created a virtual machine… And after a month you notice that you run low on disk space… If you have disk space left on your host machine you can grow the disk and then let the running guest OS resize it to the new given size. This action requires VirtualBox to be installed. […]
In Mac OS X El Capitan, Apple added SIP (System Integrity Protection), previously referred to as rootless mode in the beta releases. SIP is essentially just a block on editing the /System, /sbin, and /usr directories (with the exception of the /usr/local subdirectory). It is recommend keeping SIP enabled whenever possible, so enable it again after you have finished making changes, unless an application […]
Default for most accounts I create I use SSH keys, therefore I do not want accounts to have a password set. Instead of leaving the password blank it is better to disable logging in using a password. This can be done with the following command:
|

pw mod user "$USERNAME" -w no |
You can check the result with vipw For example, […]
