Hi everyone! I would like to be able to get this animation in js or css, where by scrolling down or up the text is shown in Italian or Japanese. You can see the animation at this link. At the bottom of the page. I don't know where to start, has anyone ever come across this? can you help me? thank you in this link you can see the effect I try to achieve: https://ibb.co/hXs7bhs official link: https://store.google.com/it/product/pixel_buds

I searched the internet and found this library (https://github.com/ericblade/quagga2) that is right for me. Now I would like to be able to implement code 32, I read on the internet that the conversion is the same as code 39 (already existing in the library), I created this file and added it to the list of barcodes to use, but it doesn't work, I also found this on the internet for coding ... can you tell me where am i wrong? file created by me : code_32.js import BarcodeReader from './barcode_reader';

Hello everyone, I need some information for sending sms with whatsapp via PHP function ... I would like to know first of all if the service is free and if it is possible to do so, without joining any third party service such as Twilio .. Have you already encountered this problem? Do you have any idea? Thank you P.S. I don't need to receive a reply to the message from the recipient. Just send me a message

Ok, but the default iOS and Android app does not damage the ability to access your health data to json, that is, it does not guarantee APIs to be implemented via js / php? Thanks for the reply!

Good morning! I was wondering how can i access the php data to the health data (steps, heart rate etc ..) of devices with android and ios? I don't know maybe by inserting the keys I can access the json with the related data... I tried to search a bit on the internet but I see that I can only do it if I create an app for both systems and then from there I enter the data in my mysql database.. I don't know where to start, do you know something? Thank you

Thanks so much!

In case using $ _SERVER ["REMOTE_ADDR"]; to get the name of the dns how can I remove all those characters and know only the final part? For example: With that function I get this: mob-3-91-125-82.net.vodafone.it host86-197-dynamic.3-87-r.retail.telecomitalia.it 93-32-55-29.ip32.fastwebnet.it mob-5-90-154-87.net.vodafone.it I would like this instead: net.vodafone.it retail.telecomitalia.it ip32.fastwebnet.it That should be the name of the internet provider I connect to. Thanks

what I need is the name of the device I am using to access a site. for example PC-Fra. Anyway thank you for replying 😊

I don't have any software installed on my pc regarding DropBox, yet it gets my device name. If I connect to their site

Is there no way to get it? For example using JS. That is, how does DropBox, for example, obtain the name of the logged device?

Hi everyone, I'm trying to get the name of the machine in use. If I use this feature locally, it works. function visitor_machine_name(){ $machine_name = gethostbyaddr($_SERVER['REMOTE_ADDR']); return $machine_name; } But as soon as I try it on an online server I get the DNS name back, like this: mob-3-91-125-82.net.vodafone.it What can I do?
