4t Upload speeds

My 4G let connection has 10mbps+ upload speeds. So why is it so slow uploading photos and videos to the cloud? What’s slowing it down? Clover345 (talk) 07:57, 11 July 2018 (UTC)

Three things, high latency, where it takes dozens of milliseconds for each message to get through; ssecond, you have to share that network capacity with all the other people using it in the same sector. Third if you are a long way from the cell site antenna, the data rate will be lowered, as your phone transmitter has limited power. If you were the only customer, then you could get the maximum available capacity whenever you wanted. Graeme Bartlett (talk) 00:38, 12 July 2018 (UTC)
But in many other countries I’ve experienced very fast 4g. I think the uk must have some of the worst 4g in the world. — Preceding unsigned comment added by (talk) 13:40, 15 July 2018 (UTC)

Translatewiki won't let me translate into Central Sierra Miwok how can we get them to add it as an option?

There is an ongoing Central Sierra Miwok wiktionary and also a proposed wikipedia, tests created for both. We need to start translating the interface and 500 most common messages. Can someone please intervene?Baymiwuk (talk) 08:18, 11 July 2018 (UTC)

Central Sierra Miwok is a Miwok language spoken in California, in the upper Stanislaus and Tuolumne valleys, with reportedly 12 native speakers in 1994. The website for Translatewiki computer-assisted translation is where you can find out how to start a localisation project for a language or check their list of languages which are waiting for translators to work on them. DroneB (talk) 14:55, 11 July 2018 (UTC)
Where on translatewiki, there doesn't seem to be a way for me to be able to put in the request and central sierra miwok is not yet an option to translate into, please helpBaymiwuk (talk) 08:24, 13 July 2018 (UTC)
At the bottom here it says "Please contact us, on our IRC channel, by e-mail, or at our support page." with appropriate links. DroneB (talk) 18:18, 13 July 2018 (UTC)
What's the email address? The IRC doesn't work for me, where's this support page?Baymiwuk (talk) 02:57, 15 July 2018 (UTC)

two different questions

The 1st regards logging in to Twitter, the 2nd regards, probably, Windows.

(1) I've 2 accounts in Twitter, each being installed initially in a different browser: Chrome & Edge, respectively. From some unknown reason, I've found out that I can't log in to the other account from the 1st browser, and vice versa in the 2nd.

(2) From time to time, with no apparent reason, the current web window on the screen suddenly and momentarily blackens & freezes. Why is it so ? A malfunction ? Solution ?

Thanks for any effective reply, בנצי (talk) 18:38, 11 July 2018 (UTC)

Question 1 is going to be difficult to answer without more info. What do you mean you can't log in to the other account? After logging out of the account in the browser and when you try to log into the other account in the same browser by correctly entering the username and password and trying to log in, what happens? Is there an error message? A blank page? Or if get a 2FA request, what happens after you correctly submit the 2FA code? Or have you been unable to work out how to logout properly and get a login page? (If so, the better question would have been 'how do I log out so I can login to another account'. Note that very few sites allow simultaneous login from multiple accounts in the same browser session. Google is one of the very few.) Nil Einne (talk) 04:46, 12 July 2018 (UTC)
Thank you for your response. What's "2FA" ? I meant that I can't enter account B on browser 1, & can't enter account A on browser 2. My username & pwd were checked, to make sure of it, twice, by logging out and in again, in the respective original browsers. When I try to relog in to the 'wrong' account, it says: "The username and password you entered did not match our records. Please double-check and try again". Maybe it has to with other data beyond username & pwd ???? בנצי (talk) 07:31, 12 July 2018 (UTC)
He may be hitting the Twitter rule that says that you can have only on twitter account associated with a single email account, or he may have been affected by this: [1] --Guy Macon (talk) 05:36, 12 July 2018 (UTC)
Thank you too. No, each has its own email address. The main reason for managing two accounts is using two different languages, where each is destined to different audiences. בנצי (talk) 07:31, 12 July 2018 (UTC)
This is fairly weird but to make sure you don't just keep screwing up somehow, e.g. autocomplete conflicts. There's no need to check lots of times. Instead write your username and password into a temporary storage space e.g. Notepad on Windows. Go to the login page of both browsers. Make sure the username and password fields are completely empty. E.g. backspace a few times until you are sure you are at the beginning and then delete a few times to make sure there are no spaces. Copy the username and paste it into the relevant field on both browsers. Copy the password into both browsers. (Note you should only ever copy the username and password one time each. Do not copy for each browser. Likewise if you screw up and e.g. paste the password onto the username field. Start from the beginning including making sure you clear both fields.) Click login for the browser you expect to fail. If it still fails, try in the browser you expect to succeed. Nil Einne (talk) 20:20, 12 July 2018 (UTC)

Deleted emails

Today, the FBI agent Peter Strzok is testifying in Congress. And this brings to mind the issue of the Hillary Clinton email controversy. Long story short, sometimes people are accused of deleting emails. And then law enforcement (or the FBI) cannot "find" those "missing" emails. So, here is my question. Let's say that John (at his G-Mail email address) emails Mary (at her Yahoo email address). Let's further say that John (successfully) deletes all of his emails, and Mary does the same ... through wiping out the hard drive or with Bleach Bit or whatever. My question is: doesn't G-Mail and/or Yahoo still have copies of these emails somewhere? On their servers or on the cloud or somewhere? Thanks. Joseph A. Spadaro (talk) 23:50, 12 July 2018 (UTC)

It would depend on their retention policies. Deleting an email on Gmail, for example, sends it to a trash folder on Google's servers where it's "permanently" deleted after 30 days (unless you manually delete it sooner). This article and this one (both fairly old) say that offline backups are kept for 60 days after that. Google appears to be cagey regarding what's kept beyond that or for how long. See also Exporting & deleting your information and How Google retains data we collect for Google specific policies. As with most online services, the truth is buried deep within the terms of service and/or obfuscated by legalese. clpo13(talk) 00:19, 13 July 2018 (UTC)
Or that information isn't public at all. -- (talk) 07:48, 13 July 2018 (UTC)
Clinton famously used her own email server in order to prevent the possibility of someone else retaining copies of the email. That she wiped it "with a cloth" became the subject of many jokes. (talk) 02:45, 16 July 2018 (UTC)

MS Word

How do I print on hard copy, the wavy red, green and blue lines that usually is/are displayed when grammatical errors occur? (talk) 15:19, 13 July 2018 (UTC)

They are to help on-screen review and don't appear on hard copy, you are not forced to agree that they are errors. Use Alt-PrtSc and then in MSPAINT ctrl-V to make a printable document of exactly what is on your screen. DroneB (talk) 18:05, 13 July 2018 (UTC)
(edit conflict) There's no built-in way to do this. This old discussion (regarding Word 2003; also see [2]) gives an idea of how to find spelling errors in a document and put an actual wavy, red line under them using a Visual Basic for Applications macro. I was able to run the macro on Word 2016, though it would take some modification to also do green and blue underlines. clpo13(talk) 18:09, 13 July 2018 (UTC)

Limiting who can connect to a remotely-accessible home server

I have a home server that I am configuring for remote access. The public IP of the server is assigned by my cable company, so I'm using the dynamic DNS updating service provided by NoIP to give the server a public-facing domain name. This works, but the problem is that anyone can type in that name and access the services with proper authentication: for example, if my server is running RStudio on port 8787, anyone can type <servername>:8787 and get the RStudio login. When I've worked remotely in IT, if I wasn't logged in through the company's VPN (usually Cisco AnyConnect), I'd get an error when I tried their internal sites ("this site can't be reached"). I'd like to replicate that functionality on my home server, but I'm not sure how, or if it is even feasible. OldTimeNESter (talk) 22:04, 13 July 2018 (UTC)

That IT company had a server located in their internal network inaccessible from the outside. To get access to the server you needed to connect to their internal network using a VPN server provided by them. Here you use a different configuration. Yes, theoretically you can set-up a VPN server for you home network and limit access to your server only to the local hosts. Thus you will need to connect to the VPN first before you can access the server. Ruslik_Zero 06:17, 14 July 2018 (UTC)
Thanks for the quick response. How difficult is it to setup my own VPN server? Is there open-source software available for that? Also, will the VPN server need to be a different server than the one I currently have (either a physically different machine, or a different VM running inside the home server)? OldTimeNESter (talk) 20:27, 14 July 2018 (UTC)
Possibly one of your best options would be to run a remotely available SSH server, and then tunnel any connections you need through SSH. Or you might want something like OpenVPN (which is no easier to set up). Usually a router would allow you to specify which services are available remotely - you want to limit your remote exposure to one properly secure service if you can. It can be a pain setting up secure connections properly, but it's worth it. -- zzuuzz (talk) 21:12, 14 July 2018 (UTC)

"file not found" (Word and Notepad)

This happened once before and then the problem went away. Now it's back.

Attempting to Save or Save As in Word or Notepad, I get a file not found" message and am advised to "Check the file name and try again". In the first case the file is actually there (I just opened it) and the second case is not logical.

What can I do?

Thanks. --Halcatalyst (talk) 14:57, 14 July 2018 (UTC)

I've had the same problem occasionally. It happens to me on an old and slow computer, and I've assumed that it was just too slow in opening the folder to save the file, resulting in a confusing error message from Windows. Dbfirs 06:30, 16 July 2018 (UTC)

What does it mean to tap?

Something went wrong on Facebook a minute ago and I was told to tap to try again (on my desktop computer). I used my mouse to click because that's all I know to do. Sometimes when I pay with a credit card there's a little screen and one of the options is to tap. I went to tap and didn't see an option that looked right. Which article on Wikipedia describes this action or actions? — Vchimpanzee • talk • contributions • 17:06, 14 July 2018 (UTC)

(Converted URL to a standard wikilink for reading convenience.) -- (talk) 06:23, 15 July 2018 (UTC)
Thanks, but that actually does little but refer me to another article with more detail, which should probably have been the link in the first place. Can someone look at what I did and see if it is satisfactory.— Vchimpanzee • talk • contributions • 17:18, 15 July 2018 (UTC)
Yes. "Tapping" = "To click on a touch screen". However, that's really beside the point - did Facebook do what you wanted it to? If it did, you did the right thing and I'm not sure what you're really looking for. If it didn't, we could be more helpful if you explained what went wrong. Matt Deres (talk) 02:24, 16 July 2018 (UTC)
No, Facebook didn't do what I wanted, and I'm not sure what it was supposed to do because it was just an ad or something and not what I was actually wanting to do. The important thing is making sure the Tap page had the right link.— Vchimpanzee • talk • contributions • 17:10, 16 July 2018 (UTC)
I've updated the appropriate link on the tap page to go directly to Pointing device gesture instead of getting there via soft redirect. Matt Deres (talk) 18:28, 16 July 2018 (UTC)

────────────────────────────────────────────────────────────────────────────────────────────────────Thanks. We still have the problem of a separate computing section, which may be where your change should go. I don't know.— Vchimpanzee • talk • contributions • 16:44, 17 July 2018 (UTC)

How To Activate Windows 10 Pro

Hi I have a problem on how to activate windows 10.I tried to use product key but its didn't work its gives me errors.i tried activating it online but still, i tried using commands prompt still its not working'

Its will be a pleasure if to help me Thank you. (talk) 13:53, 15 July 2018 (UTC)

Our article is in Microsoft Product Activation. Are you sure your product key is genuine and not fake or stolen? Graeme Bartlett (talk) 14:29, 15 July 2018 (UTC)
The product key could also be tied to a specific Microsoft account. For example, whenever I reinstall Windows 10, instead of activating it with a product key I sign into my Microsoft account to activate Windows. Random character sequence (talk) 15:17, 16 July 2018 (UTC)

Mp3 program frequency, fidelity?

Why do programs differ when reproducing mp3? Assuming it's the same file played with the same hardware, and discounting aspects like user-friendliness. That is, it's only about the sound been played. Are they something like browsers, that render a page differently, or, would it be more life a pdf reader, that aspires for consistency? --Doroletho (talk) 17:58, 16 July 2018 (UTC)

Your initial assumption is incorrect: unless they're actually broken, they all sound the same -- see MP3#Encoding_and_decoding. Any difference you hear is either imaginary, or the result of some other processing which your device is using, such as an equalizer or volume control. HenryFlower 20:36, 17 July 2018 (UTC)

Browser Security

Have I been Hacked? I received a pop-up while on Wikipediathat says: Your Browser's Connection Security is Outdated ________________________________________ English: Wikipedia is making the site more secure. You are using an old web browser that will not be able to connect to Wikipedia in the future. Please update your device or contact your IT administrator. ________________________________________ We are removing support for non forward secret ciphers, specifically AES128-SHA, which your browser software relies on to connect to our sites. This is usually caused by using some ancient browsers or user agents like old Nokia smartphones or Sony Playstation3 gaming consoles. Also it could be interference from corporate or personal "Web Security" software which actually downgrades connection security. You must upgrade your browser or otherwise fix this issue to access our sites. This message will remain until Aug 1, 2018. After that date, your browser will not be able to establish a connection to our servers at all. See also the HTTPS Browser Recommendations page on Wikitech for more-detailed information.

I have Safari Version 11.1.2 (12605.3.8.1) MacOS Sierra Version 10.12.6

Is this message legitimate? Does it apply to me? Where can I get useful info on this? Is this the correct place to ask this question? (talk) 02:07, 17 July 2018 (UTC)

  • The message complains about your browser trying to create a secure connection (HTTPS) using an old, outdated cryptographic protocol likely to be broken (hence not secure at all). It is virtually certain that Safari 11.x has support for newer ciphers (unless you played with it - any weird addons installed?) so something sounds fishy.
I see two possibilities, neither of which strike me as probable. One is that the WP server is somehow misconfigured (it could happen) in which case you should go to WP:VPT. Another is that someone is pulling a downgrade attack between you and the server. Which network are you accessing Wikipedia from? TigraanClick here to contact me 17:20, 17 July 2018 (UTC)
I see the hostname for your IP is "" and it looks like a static IP assigned to Hawaiian Telcom. This suggests to me a simply home internet connection. Am I right? If so who owns or set up the computer you are using? If it is a work computer, as the message says it could be some corporate security software. If this is a home computer, while this is MacOS X and I believe such software are a lot rarer, are you sure you haven't installed some security software or as Tigraan mentioned a browser plugin that may interfere?

Keylogger and copy paste

If one copy pastes "bunny", does a keylogger know that the word was "bunny" or just that a copy paste of 5 letters happened? Anna Frodesiak (talk) 05:16, 18 July 2018 (UTC)

Depending on the keylogger - it can know "bunny". The article refers to it as clipboard logging. (talk) 06:09, 18 July 2018 (UTC)
Ah, yes. Thank you. I did not see that at the keystroke logging article. Cheers. Anna Frodesiak (talk) 08:00, 18 July 2018 (UTC)

why are there so many gpu card brands?

If you want to buy a GTX 1080-based graphics card, for example, there are dozens of brands to choose from, including NVidia's own. Similarly for (say) Radeon 680. But they all have the same chip inside. There don't seem to be any significant functional differences unless you count unusual features like water cooling. I hope nobody cares much about cosmetic differences, since the card will normally be out of sight inside a computer anyway. Is there a reason to not just get the chip manufacturer's board? I'd hope that if anyone can get it right, they can. Thanks. (talk) 06:18, 18 July 2018 (UTC)

GPU manufacturers typically don't produce video cards themselves, but rather sell chips to add-in board partners who would either do a reference or custom design. It's part of their business model from what I can tell. As for different variants of the same thing, would it be a proper analogy to compare that to other consumer brands, say different detergent brands (or variants of the same soap) from Unilever? Even a high-end part like a 1080Ti may have "entry-level" or base configurations as not everyone would want or need an overclock or water cooling. Blake Gripling (talk) 07:36, 18 July 2018 (UTC)
