It used to just let me log in with my username and password, and remembered both on my home PC, but now they started adding captchas randomly, without even asking if I wanted them, which I find intensely annoying. How do I turn them off ? StuRat ( talk) 04:38, 28 April 2017 (UTC)
I should point out that the login panel has changed, so this new security feature may just come with the new login screen. StuRat ( talk) 19:30, 28 April 2017 (UTC)
I have to test a page interacting with cam on Chrome. So I'm trying to launch Chrome with option '--user-data-dir=/test/only/profile/dir', yet I get the error 'Chrome cannot read and write to its data directory', although I set custom permissions to AppData Chrome folders.. Could you please help me?

What do these two cron expressions mean?
Start time:
0 0/1 * 1/1 * ? *
Stop time:
0 0 2 ? * * *

man 5 crontab
on the NETBSD UNIX system I have access to, "?" means "a single value randomly selected when the crontab file is read". For example, if it's in the hour field for an action to be performed daily, that action might be performed at 03:00 every day and then change to 23:00 when the system is rebooted or the crontab file is changed. And / means "every nth". For example, in the hour field */2
means hours 0,2,4,...,22 of the day, or 0-10/2 means 0,2,4,6,8,10. So as far as I can see it makes no sense to write /1
or to use / with a single number on the left.They are start and stop times for a subscription. Thanks for the responses! † dismas†| (talk) 20:25, 1 May 2017 (UTC)
I can get an iphone 5S cheap that has a bad battery. Rather than replacing the battery I'm thinking of removing it completely, and using an external power pack like a Mophie. Does anyone know if the 5S works ok with no internal battery? Yes I know it's easy to replace, but I don't like the iphone feature that it's impossible to know that it's completely powered off. Unplugging the external battery would fix that. Thanks. (Also: how long does it take to cold boot a 5S from powerup? Same question for Ipod Touch 6th gen I guess). 173.228.123.121 ( talk) 14:38, 28 April 2017 (UTC)
This advice is questionable. Whatever crap Apple may say, unless you screw up when you remove or dispose of the battery and it catches fire, there would have to be something incredibly wrong the iPhone for it to catch fire just because the battery is removed. Software design specification for the battery controller etc are red herring since the OP specifically said they aren't planning to replace the battery. They're simply going to use it without a battery but without an external power plug. The iPhone may not be designed to be used without a battery (as I said below, it most likely simply won't work) but it should be sufficiently designed such that it won't catch fire when someone does try to use it without a battery unless Apple designers are complete idiots. And hopefully you Nimur can attest that they're not. The battery pack the OP is using, if it's a decent one, will have it's own built in safety, such that even if the iPhone does try to do something stupid like draw 10A, it will prevent this and definitely prevent the lithium ion battery inside the battery pack from catching fire. If it doesn't then it's a piece of junk and having access to a wealth of Apple technical document doesn't help. (In other words, protecting the battery in the power pack is largely the responsibility of the power pack designers, not Apple.)
Now removing a non removable lithium ion battery isn't without risks, and yes you could cause a fire if you majorly screw up. Definitely you should have knowledge of the risks involved, and how to deal with them before trying it. But you do not need, and we can be fairly sure not even all Apple certified repairers know all that info about the software controller etc. It's not germane to what they're doing, which is solely to open the iPhone and remove the battery. Even if they have access to the documentation, it's largely a moot point. If you accidentally poke a hole in the battery, you need to know what to do right now, not read up on crap about the software controller. (Of course you should be sufficiently competent that this never happens.) Disposing of the battery safely is another minor concern, hopefully your jurisdiction has some sort of hazardous waste scheme to deal with. But anyway, even if you do something incredibly stupid like throw the battery out with the regular trash, maybe you'll cause a fire in the rubbish truck or dump (in reality probably not), but it's not going to affect your iPhone and battery pack. Well unless the fire spreads to your house or something.
Definitely the people who install the battery in the China in the first place do not know any of that stuff, although it's obviously a lot harder to safely remove a battery than it is to safely install it in the factory. A middle ground would be those who are helping in the recycling of the iPhone. Apple doesn't have the capability (nor I'm thinking the policy even in a number of places where they official sell the iPhone) to be the ones collecting all iPhones for recycling. [2] This means it's down to other ewaste experts to deal with. And we can be fairly sure these people do not have, and it would be ridiculous to expect them to have, all that info before they remove the iPhone battery. They just need the technical expertise on how to safely remove the battery (including what to do if something goes wrong), and what to do with it after.
The headphone socket on my Toshiba laptop is going. I have to hold the jack in place or I lose some of the audio. Will a headset connected to a USB port give me the equivalent audio quality? I assume buying one of those will be cheaper than getting the socket repaired or replaced. Rojomoke ( talk) 22:27, 28 April 2017 (UTC)
