What are you talking about, and why should I care?

Now that we live in the Big Data, Web 3.14159 era, lots of people want to build databases that are too big to fit on a single machine. But there's a problem in the form of the CAP theorem, which states that if your network ever partitions (a machine goes down, or part of the network loses its connection to the rest) then you can keep consistency (all machines return the same answer to

How to setup Vortex Race 3 for Mac with latest (on 2020-01-05) firmare V1.02.05.

For better understanding we will use the following naming convention:

  [ L1 ][ L2 ][ L3 ][ Space ][ R1 ][ R2 ][ R3 ]

1. Reset everything by pressing L3+R1 for 5 seconds. Left LED will blink white color while you're holding the keys. Release them after it stopeed blinking.
2. Get into one of the programmable layers (R2+RShift) – I like red, the super bright laser LED is the least super annoying in red.
3. Put the keyboard in Windows Mode (Pn+W), it's the least problematic one.

Let's say I have a particular commit (for example, a gerrit patchset), with a whole bunch of merging history. I want a single commit of all its changes against master, without having to walk through a huge rebase of the intermediate commits.

slow

This bash script offers quick shortcuts to simulate slower network connections. It is useful when you need to simulate a wireless network on a Linux network server, especially when you are using a virtual machine guest on your local machine or in the cloud.

slow 3G                   # Slow network on default eth0 down to 3G wireless speeds
slow reset                # Reset connection for default eth0 to normal
slow vsat --latency=500ms # Simulate satellite internet  with a high latency
slow dsl -b 1mbps         # Simulate DSL with a slower speed than the default

slow modem-56k -d eth0 # Simulate a 56k modem on the eth1 device. eth0 is unchanged.

Installation of Erlang R16B03-1 and 17.0-rc2 to OS X 10.9.2 with Xcode and wxWidgets 3.0.0

• Note: always set umask 022 for system-shared libraries
• See http://blog.equanimity.nl/blog/2014/02/09/erlang-r17-rc1-on-osx-with-wx-and-a-working-observer/ for the details
• wxWidgets 3.0.0 works the same in R16B03-1 and 17.0-rc2
• Note well: wx:demo() on OS X 10.9.2 with wxWidgets 3.0.0 is still unstable, though observer:start() is more stable.
• If you really don't have time, try Erlang Solutions' 32bit (not 64bit) distribution at https://www.erlang-solutions.com/downloads/download-erlang-otp to use it as a debugging console.
• Update 28-FEB-2014 0230UTC: Leo Liu reports brew install wxmac --disable-monolithic will do. See http://erlang.org/pipermail/erlang-questions/2014-February/077952.html.
