The most important and obvious difference between TTD and rr is that TTD is for Windows and rr is for Linux (though a few crazy people have had success debugging Windows applications in Wine under rr).
TTD supports recording of multiple threads in parallel, while rr is limited to a single core.
On the other hand, per-thread recording overhead seems to be much higher in TTD than in rr. It's hard to make a direct comparison, but a simple "start Firefox, display mozilla.org, shut down" test run on similar hardware takes about 250 seconds under TTD and 26 seconds under rr.
Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32 processes. Unix sockets allow inter-process communication (IPC) between processes on the same machine.
所以這讓跨 process 溝通的方式又多了一種，而 Unix 的程式如果要移植到 Windows 上，至少這塊有相容... (相容性與 bug 還不知道情況 XD)
Amazon Web Services now offers an AWS Deep Learning AMI for Microsoft Windows Server 2012 R2 and 2016.
然後 driver 與常用的東西都包進去了：
The AMIs also include popular deep learning frameworks such as Apache MXNet, Caffe and Tensorflow, as well as packages that enable easy integration with AWS, including launch configuration tools and many popular AWS libraries and tools. The AMIs come prepackaged with Nvidia CUDA 9, cuDNN 7, and Nvidia 385.54 drivers, and contain the Anaconda platform (supports Python versions 2.7 and 3.5).
Also, Git wasn't designed for a codebase that was so large, either in terms of the number of files and version history for each file, or in terms of sheer size, coming in at more than 300GB. When using standard Git, working with the source repository was unacceptably slow. Common operations (such as checking which files have been modified) would take multiple minutes.
Savitech provides USB audio drivers for a number of specialized audio products. Some versions of the Savitech driver package silently install a root CA certificate into the Windows trusted root certificate store.
Mitre assigned this exposure the identifier CVE-2017-9758, but was initially tracked by HITCON ZeroDay project as ZD-2017-00386.
有兩把 CA public key 被塞進去。雖然目前還沒有徵兆 private key 有外洩，但還是建議儘快移除：
There is currently no evidence that the Savitech private key is compromised. However, users are encouraged to remove the certificate out of caution. The two known certificates are:
SaviAudio root certificate #1
Validity: Thursday, May 31, 2012 - Tuesday, December 30, 2036
Serial number: 579885da6f791eb24de819bb2c0eeff0
SaviAudio root certificate #2
Validity: Thursday, December 31, 2015 - Tuesday, December 30, 2036
Serial number: 972ed9bce72451bb4bd78bfc0d8b343c
另外 Savitech 也放出了新版的 driver，不包含 Root CA：
Savitech has released a new driver package to address the issue. Savitech drivers version 220.127.116.11 or later do not install the root CA certificate. Users still must remove any previously installed certificate manually.
看了一下說明，看起來是當時為了支援 Windows XP 而做的，但微軟已經不提供驅動程式的數位簽章了，所以就只好這樣搞...
As Microsoft notes, "to protect customer privacy, no data is shared or transmitted until permission is granted," and no information is sent until "processing has determined cheating is likely to have occurred."
You can try out a 512 MB server for one month (up to 750 hours) at no charge.
不過不是所有 Amazon Lightsail 有開的區域都支援 Windows：
