Using the default Elsevier latex template, there is a URL in each bibliography reference with “Bdsk-Url” fields. To remove this URL,
1. Open the BTS (bibliography style) file being used (by default “els article-num.bst”).
2. For each BibTeX item type (e.g. “inproceedings”), find the corresponding function in the above BST file (e.g. “FUNCTION {inproceedings}”), then comment out “write.url” in the end of this function (i.e. change it to “%write.url”).

(To remove such URLs for IEEE template, please refer to http://writebuffer.com/remove-url-in-ieeetran-bibliography-on-mac-os/)

If you have better solutions, please let me know. Thanks.

I installed the NVIDIA Web Driver on my MacBook Pro (Mid 2014 w/ GT750M) due to sluggish High Sierra. At first, it seemed to improve the graphics performance a bit. However, when I tried to restart the MacBook later, it just stuck on Apple logo with progress bar not finishing moving.

In Safe Boot, I can’t access the NVIDIA Driver Manager. Right now my solution is to clear the Macbook’s NVRAM (nonvolatile random-access memory). Caution: it will also reset several other settings. The method is: press Option, Command, P, and R together, and then start the computer.

If you have better solutions, please leave your comments. Thanks.

Several times after I force-restart my Mac (recently in High Sierra), I found Safari lost all its saved passwords. It seems the Mac loses the keychain containing these passwords. The solution may be simple:
Go to System Preferences -> iCloud, if “Keychain” is unchecked, check it. Then all passwords should be accessible in Safari again.

This method is learned from https://www.digitalocean.com/community/questions/how-to-change-swap-size-on-ubuntu-14-04:

(change count=1024 for the size you need)

sudo -s
swapoff -a
dd if=/dev/zero of=/swapfile bs=1M count=1024
chmod 0600 /swapfile
mkswap /swapfile

I upgraded my TS140 with new motherboard (B250), CPU (i7-7700K), power supply, and cooler. Here are some notes:

1. Standard MicroATX MB can be installed perfectly.

2. To conveniently connect SATA cables, it’s better to choose a MB with upward (instead of sideward) SATA connectors.

3. To connect the power front panel on TS140, refer to:
(1) the pins for TS140: https://forums.lenovo.com/t5/ThinkCentre-A-E-M-S-Series/ThinkCentre-front-panel-connector-power-audio-and-USB-pinouts/td-p/190651
(2) the system panel connector (F_PANEL) on your new MB.

4. If using tower cooler, be careful of the total height. I use one with 125mm height.
