Smartphone battery charging: You’ll probably do the best for your smartphone’s battery if you leave it charged between 50 to 80 percent full.

Quote from “Is It Safe to Leave My Smartphone on My Wireless Charger? 4/19/2019 by David Murphy” on

. Don’t top it off, but also don’t let it get too low. Let’s continue. Here’s another article from Digital Trends’ Simon Hill, published last year:
“Electrical energy is changed into chemical energy during charging and the reverse happens during discharge,” Dr. Daniel Abraham, senior scientist at the Argonne Laboratory, told Digital Trends.

. The battery manufacturer decides how much energy can be stored in the cell, and that determines how much energy you have available to use.
“The manufacturer decides the upper cut off voltage and the lower cut off voltage, which are fixed, and cells cycle between the two voltage ranges,” Dr. Abraham explained. “As long as you choose the voltage range appropriately, you can cycle the cell thousands of times.”
“It doesn’t matter if you have a wireless or wired charger.”

. It’s not possible to exceed these limits by leaving your phone on the wireless charging pad for too long, or by leaving it plugged in overnight. You also can’t drain the cell beyond the lower cut off limit dictated by the manufacturer. These limits don’t distinguish between power sources.
“It doesn’t matter if you have a wireless or wired charger,” Dr. Abraham said. “You won’t be able to overcharge or over-discharge a cell.”Hill also touched on the whole power cycling issue I previously mentioned, and noted that the best way to ensure you aren’t using up more of your device’s limited battery cycles needlessly, you should take a good look at which apps are running in the background on your device. That will probably have more of an impact on your overall battery life than using your wireless charger more than you think is normal.

. As well, make sure your wireless charger isn’t located, say, in front of a window. Heat will affect your smartphone’s overall battery life. While it might get a little warm from the wireless charging, it’ll get a lot worse if you’re letting it charge and tan.
So where does that leave us? Here are the key takeaways, from what I gather:

. You’ll probably do the best for your smartphone’s battery if you leave it charged between 50 to 80 percent full. You can keep it higher, which might affect its lifespan. You can drain the battery lower, but you’ll start using up more of your battery’s power cycles when you do. Leaving your smartphone on its wireless charging pad won’t destroy the battery. It might have some kind of an effect on its lifespan, but there are other things that are much worse. Make sure you’re getting a reputable charging pad—not some sketchy Amazon knockoff—as an overheating pad (and overheating device) could potentially affect your battery life… and who knows what else. Don’t let your smartphone charge in the sun, whether that’s on your desk, on a long car trip, et cetera.Get rid of apps you don’t need / don’t let apps run in the background for no reason.

About NoScript extension for Firefox web browser

Learning something new today from “NoScript guide for Firefox 57+ by Martin Brinkmann on August 13, 2018 on

. Terminology:

Script — Any type of script the site attempts to execute. Object — The HTML object tag. Media — Media elements. Frame — Frames that the site attempts to load.Font — Font elements. WebGL — WebGL elements.Fetch — requests that use fetch APIs.

. Using NoScript
Understanding how NoScript trust levels work is essential to using the extension to its fullest potential.
NoScript indicates blocked items in its icon when you load sites in the Firefox browser. A click on the icon displays the connections the extension recognized and trust levels for each site. Note that these may not be all connections a site makes. Since you don’t allow the execution of scripts by default, sites may not be able to initiate all third-party connections right away.
If you allow scripts to run on the main domain, you may notice that it attempts to make additional connections when those get loaded.
Tip: Hover over any domain listed by NoScript and click on it to open a page that is full of links to privacy and security services only to display information about the domain.
It may not be necessary to make any changes to trust levels if the site functions properly. You may notice however that some features may not work properly on first connect.
Since scripts and other elements are blocked by default, you may notice all sorts of issues related to that. Sites use scripts and other elements for a variety of things, from verifying form submissions and playing videos to often unwanted things such as advertisement or tracking.
Changing a domain’s trust level to “trusted” or “temporarily trusted” allows it to load additional elements whereas a trust level of “untrusted” prevents even more elements.
Note that trusted and untrusted are permanent changes that remain available.
Troubleshooting a site comes into play when you notice that site functionality is not available and suspect it is because of the protections that NoScript provides.
You have a couple of options to deal with the issue. You could temporarily allow a domain or use the custom trust level to set permissions individually for elements.
. Terminology:Script — Any type of script the site attempts to execute.Object — The HTML object tag.Media — Media elements.Frame — Frames that the site attempts to load.Font — Font elements.WebGL — WebGL elements.Fetch — requests that use fetch APIs.

Learning about Thunderbolt 3, USB-C, USB 3.1 2nd Gen. connections

Learning about Thunderbolt 3 and USB-C connections from “USB Type-C and Thunderbolt 3: One port to connect them all” on
. Here’s how Thunderbolt 3 is different from its predecessors:
The Mini DisplayPort connection type has been ditched in favor of a USB-C connection type.All Thunderbolt 3 cables will work as USB-C cables.All USB-C cables will work as Thunderbolt 3 cables as long as they are good quality cables.Thunderbolt 3 has a top data transfer speed of 40Gbps as long as the cable is 0.5m (1.6 ft.) or shorter.For 1m (3.2 ft.) or longer cables, Thunderbolt 3 supports passive (cheaper) ones that have a top speed of 20Gbps, and active cables (more expensive) that retain the 40Gbps speed.Thunderbolt 3 is backward-compatible with earlier versions of Thunderbolt, but due to the new port type, adapters are required to use legacy Thunderbolt devices.Any USB-C device (like a Google Pixel) plugged into a Thunderbolt 3 port will function normally.Since Thunderbolt 3 devices use discrete Thunderbolt chips to function, they will not function if plugged into a USB-C port.All versions of Thunderbolt allow for daisy-chaining up to six devices together to a host and in addition to data, can also carry Hi-Def video and audio signals.
. USB 3.1 (sometimes refereed to as USB 3.1 Gen 2., [or now called SuperSpeed+ or SuperSpeed USB 10 Gbps)): Released on July 26, 2013, USB 3.1 doubles the speed of USB 3.0 to 10Gbps (now called SuperSpeed+ or SuperSpeed USB 10 Gbps), making it as fast as the original Thunderbolt standard. USB 3.1 is backward-compatible with USB 3.0 and USB 2.0. USB 3.1 has three power profiles (according to USB Power Delivery Specification), and allows larger devices to draw power from a host: up to 2A at 5V (for a power consumption of up to 10W), and optionally up to 5A at either 12V (60W) or 20V (100W). The first USB 3.1 products are expected to be available in late 2016, and will mostly use USB Type-C design.

Quote from “Signs You’re Not Getting Enough Protein”

I was asking about what signs could indicate protein deficiency yesterday, 4/7/2019, and the daily mail from Time magazine appears in my email Inbox today.
Quote from “Signs You’re Not Getting Enough Protein” on
. How Much [protein] Do You Need? You should get a minimum of 10% of your daily calories from protein. (For a target of grams, multiply your weight in pounds by 0.36.) And you want it from a variety of sources throughout the day: A tub of low-fat Greek yogurt for breakfast has about 20 grams; a serving of skinless chicken breast at lunch, about 25 grams; and a cup of black beans in your dinner, about 15 grams. Your body breaks down and reuses the protein in many ways.
. Swelling One of the most common signs that you’re not getting enough protein is swelling (also called edema), especially in your abdomen, legs, feet, and hands. A possible explanation: The proteins that circulate in your blood — albumin, in particular — help keep fluid from building up in your tissues. But many things can cause edema, so be sure to check with your doctor in case it’s more serious.
. Mood Changes. Hair, Nail, and Skin Problems. Weakness and Fatigue. Hunger. Slow-Healing Injuries: People who are low on protein often find their cuts and scrapes take longer to get better. The same seems to be true of sprains and other exercise-related mishaps. It could be another effect of your body not making enough collagen. It’s found in connective tissues as well as your skin. To make blood clot, you need proteins, too.
. Getting or Staying Sick. Who Might Come Up Short? Most Americans get plenty of protein. People who don’t get enough usually have an overall poor diet. Elderly people and people with cancer may have trouble eating as much protein as they need.
. What About Athletes? If you exercise regularly and eat a balanced diet, you’re probably fine. But serious athletes with strenuous training schedules do need more protein — about twice as much as the average person, or roughly 0.5-1 gram of protein for every pound of body weight each day. Don’t overdo it though. Too much protein can also cause problems.

Steps to manually uninstall Paragon NTFS for macOS

So I learn from “How to Uninstall Paragon NTFS for macOS” on
Quote of the manual un-installation method:
Paragon NTFS for Mac is a tool that helps you to write, edit, copy and delete files on Microsoft NTFS-formatted drives connected to your Mac.Paragon NTFS application installs its pane to System Preferences, so it is not enough to drop the app to Trash to remove it correctly.

. Uninstall Paragon NTFS for Mac manually
Like most Mac users do, you may delete Paragon NTFS following these steps: go to the Applications folder in Finder → find Paragon NTFS for Mac → make a right-click and select Move to Trash → then, Empty Trash.
However, advanced users know that any application creates service files for its proper work on a Mac. Likely, you have heard or read about caches and logs. These types, in addition to other files, are the temporary helpers of an application. So, the deletion of the .app file is not enough for the application’s entire removal from your Mac. Furthermore, the temporary service files are useless without the application on your Mac. So you have to find all the leftovers of Paragon NTFS and remove them.The junk files are usually stored in the hidden Library folder. Follow these steps to see the contents of the Library folder:
Open Finder.Click Go in the toolbar and select Go to Folder in the drop-down menu.Type ~/Library in the appeared window and click Go.Type paragon in the search field in the corner of the window and hit Enter. Next, you will see all the files and folders that relate to Paragon NTFS. Select these items, move them to the Trash, and then empty the Trash.
You should also check your Mac’s System Preferences. Some applications create a System Preference pane (an application icon) on your Mac by default. Paragon NTFS is one of them. So, open System Preferences → find Paragon NTFS for Mac icon → make a right-click and Remove “NTFS for Mac” Preference Pane.
Then you should navigate and remove Paragon NTFS cache files stored in ~/Library/Caches, application support files, crash reports, preferences files, remove them as well.

韋應物《登寶意寺上方舊遊》 :翠嶺香台出半天,萬家煙樹滿晴川。諸僧近住不相識,坐聽微鐘記往年。




《詩經•小雅•出車》 :……春日遲遲,卉木萋萋。倉庚喈喈,采蘩祁祁……張炎《清平樂》:採芳人杳,頓覺遊情少。客裡看春多草草,總被詩愁分了。去年燕子天涯,今年燕子誰家?三月休聽夜雨,如今不是催花。


水悠悠繁華已過了 人間咫尺千山路

行到水窮處 坐看雲起時 
維《終南別業》中歲頗好道,晚家南山陲。興來每獨往,勝事空自知。 行到水窮處,坐看雲起時。偶然值林叟,談笑無還期

鄭板橋《山市晴嵐》雨淨又風恬,山翠新添。薰蒸上接蔚藍天。惹得王孫芳草色,醞釀春田。 朝景尚拖煙,日午澄鮮。小橋山店倍增妍。近到略無些色相,遠望依然。

涼淨風恬 人間依舊 細數浮生千萬緒
