”Internal Storage” memory¬1[edit]

How do you clean, or format the “Internal Storage” memory of a “Smart Phone”? 116.58.205.46 (talk) 05:28, 9 June 2017 (UTC)[reply]

It depends on what you mean by formatting, what kind of phone you have, and what lengths you're willing to go to. Try typing format <your phone model> into Google. See also iOS jailbreaking and Rooting (Android OS). Matt Deres (talk) 10:52, 9 June 2017 (UTC)[reply]

”Internal Storage” memory¬2[edit]

I wish to uninstall and re-install the Smart Phone, just like the way you do it on PC. What’s the process? 116.58.205.46 (talk) 05:28, 9 June 2017 (UTC)[reply]

You can try the factory reset which probably includes pressing a button for a long time at power up. Graeme Bartlett (talk) 12:02, 9 June 2017 (UTC)[reply]

Secure Connection[edit]

How do I ensure I have a secure connection from PC SHAREit to my Smart Phone SHAREit software? – Could a third party retrieve files while I’m transferring back and forth. 116.58.205.46 (talk) 05:28, 9 June 2017 (UTC)[reply]

Our article at SHAREit. Make sure you are using a secure WiFi protocol such as WPA2. Make sure that your phone software is patched to latest version. Make sure you have uninstalled any malware apps, particularly those granted access to your file system. Make sure your phone is not rooted. Make sure certificate revocation is up to date, that there are no dangerous certificates installed and try to use secure DNS. These checks can also take place on the PC with proper virus scans and malware checking. The main risk would not be data on the fly, but access to the data on the phone or the PC. If your data is worth millions of dollars, don't put it on the phone, it is too easy to lose. Graeme Bartlett (talk) 01:17, 14 June 2017 (UTC)[reply]

Dongle to Smart Phone[edit]

I wish to use my PC internet connection securely on my Smart Phone. E.g., say I went on-line using my internet dongle on my PC, than instead of using the ‘webpage’ or “Google Play Store” on the PC, I wish to use the Smart Phone for it… 116.58.205.46 (talk) 05:28, 9 June 2017 (UTC)[reply]

By "dongle", are you referring to an cable? If not, what you are trying to do makes little sense. Your computer is using wifi to connect to, likely, a router. Your phone can connect directly to the router as well. Is the issue that you've forgotten the wifi password and you want to bypass getting it by using the existing connection on your computer? Then, you should be asking how to get the password from your router or your computer settings. 209.149.113.5 (talk) 12:45, 9 June 2017 (UTC)[reply]
Perhaps OP means a USB mobile broadband modem, which allows them to connect to the internet through GSM/GPRS. Then the question is how to share the PC/laptop's internet connection to a smartphone. --CiaPan (talk) 12:16, 12 June 2017 (UTC)[reply]
Tethering? --Hans Haase (有问题吗) 11:27, 12 June 2017 (UTC)[reply]
Probably yes, but in opposite direction: a PC is internetworked and the user wants to surf the net with the phone using the PC's connection. --CiaPan (talk) 12:19, 12 June 2017 (UTC) — (ping CiaPan (talk) 13:46, 12 June 2017 (UTC))[reply]

Recent website and app design[edit]

What's the name of that new outlandish design and layout that is being introduced to many websites and apps? Samples: [1], [2], with typical switches. CSS3? I'm not sure it's the same adopted some time ago by YouTube, but looks like it. Brandmeistertalk 17:04, 9 June 2017 (UTC)[reply]

It doesn't look anything particular to me, why do you say it is new or outlandish? If it is new it is pretty crummy as it has a fixed layout rather than being fluid and so doesn't work on a smartphone nicely. Dmcq (talk) 18:35, 9 June 2017 (UTC)[reply]
It may look nice, but has been harder for me to use and get accustomed in one website and one app at least. Brandmeistertalk 19:17, 9 June 2017 (UTC)[reply]

Regex search in Notepad++ captures Non‑capturing groups. How do I stop it?[edit]

Resolved

In Notepad++ (v.7.3.3 32-bit) (On Windows7 64-bit) When I search for the regular expression:
«(?:unwanted )word»
on the string:
«The first is an unwanted word»
Then Notepad++ captures (highlights):
«unwanted word»
instead of just capturing the: «word» that I want.

Q1: Why does Notepad++ capture regex non‑capturing groups («(?: … )») ?
Q2:And how do I turn off this behavior?
-- 176.11.91.179 (talk) 19:17, 9 June 2017 (UTC)[reply]

That is because "unwanted" is part of the overall match, which is accessible as \0 in the replace expression. The "(?:...)" is telling the regex engine not to save "unwanted" separately as \1. This is more apparent if you change your search expression to "(?:unwanted )(word)" and set the replacement expression to "\1". In this case, the entire match would be saved as \0, and "word" would be saved as "\1".
What you might be looking for is a look-behind zero-width assertion like "(?<=unwanted )word", which would match "word", but only if preceded by "unwanted ". -- Tom N talk/contrib
Thanks for clearing up my misundertanding! :-)
