Air Travel – Does anything keep me from recording twice in my flight?

When I'm busy, recording my flights via the Internet is often convenient. I receive my boarding cards directly on my phone and I do not need worry about printing them before arriving at the airport. However, I also like to collect physical copies of my boarding cards. These are all fun moments of my travels, and when I can print them, I usually do it.

My question is: if I have already saved my flight on my phone, can I print another set of boarding cards at the airport? I like a lot the official papers of airports.

To make this question more general, consider the unfortunate situation of your dying phone. Having a physical backup copy of your boarding card could save you time.

Essentially, is there anything that prevents me from getting another boarding pass at the kiosk after my pre-registration?

php – Release and blocking the recording

I have a function on my website via the admin panel, which I release and blocks the registration. But suddenly, it stopped working. I do not know if I'm really doing anything wrong and coming for the light.

Under the registration button:

The update of the database occurs normally. The problem does not work. But that was and I whistled.

canon – Which camera is best suited for recording videos and movies? cinematics?

I was looking for a digital SLR camera to record videos. My goal is to record videos to make movies and music videos. I know that many camera-independent factors make it possible to create videos with a "cinematic" aspect, but I was looking for a camera that would be about to record like this: https://www.youtube.com/ watch? v = xKLui8nDMaY

Some people have recommended the Canon 80D. I watched videos of critics and it really pleased me. Even in low light, he recorded with a lot of quality (that's very important to me). He also recorded in slow motion.

But recently, it was said that for video, it was better to use the Canon M50. I was surprised not to have heard of this camera and that no one had recommended it to me before (and, of course, no one ever told me that it was recording better than the Canon 80D).

I have seen video tests on YouTube from both cameras and they record with similar quality. But I feel that the 80D records with slightly higher quality. In addition, the image of the 80D is a little darker and, therefore, whenever a video is recorded in the sunlight, you can distinguish more objects than in the m50 everything is extremely bright and for a few seconds all you can see is white. At least that was my first impression …

I've also seen a comparison between the Canon 80D and a Hollywood camera https://www.youtube.com/watch?v=rO7n5nhUHpI, and although the barrel obviously records with inferior quality, I'm always satisfied with the result. But I did not find a similar comparison with a m50.

I've also read that the m50 is no longer used for recording video vlogs, while the 80d is used for more professional video / "cinematic" projects.

But the other side, the m50 records in 4k, while the 80D records in Full HD (although I found a notice that indicates that the 80D records with better video quality). In addition, I read that the m50 records better in slow motion and has an auto focus.

So, what is the best option? Which camera is recording with higher quality? Which camera is best for the video?

Finally, if the m50 is a better option, why is it cheaper than the 80D?

recording – How to save all the screen on Windows 10?

Is there a way to save the entire screen in Windows 10?

When trying to use the Windows game bar to record (see https://www.laptopmag.com/articles/how-to-video-screen-capture-windows-10), I see that it only records windows the most recent ones you clicked on. before hitting the shortcut key of the game bar (I may be using the function incorrectly).

My current use case is that I have two monitors: a big one, where I want to save multiple windows to show something, and a laptop screen, where I have a script that I have to read (so need to capture the audio). I then edit these videos in the photo editor. I want to record all the screen of the largest monitor. How can I do this in Windows 10?

equipment recommendation – Schedule an hour of recording a video camera

Is there a video camera with which I can program the recording time (Sunday 10-12, 18-19, Monday 9-13, etc.)? A second feature is the need to take a video in a range of 10 to 200 meters. Features such as IR (infrared) for night vision and wifi are also taken into account. Since the video can be taken indoors or outdoors. It can also be used while traveling, so it should be as compact as possible.

java – recording call in the background with the help of a service (No Show Audio)

I have an application that runs in the background. As soon as the user opens the application, a service is started to record the calls and send them to a certain folder.

Today, the service identifies the call and records, but the audio sometimes misses in the show. I've noticed that if I open the app and make a call, it will register properly, but if I close the application or if it stays open for more than 5 minutes, the l & # 39; registration will be without broadcast.

Follow my code:

package com.example.call;

public class BroadcastSistemas extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            String estado = intent.getStringExtra("state");
            String num = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            String msg = null;

            if (estado.equals("RINGING")) {
                msg = "O número " + num + " está chamando.";
            } else if (estado.equals("OFFHOOK")) {
                msg = "Em ligação.";
            } else if (estado.equals("IDLE")) {
                msg = "O número " + num + " desligou.";
            }

How does the recording distance affect lens distortion and aberration correction?

If I use a lens with an extension tube, how does changing the distance between the lens and the camera affect the optical correction of distortion and distortion? Aberration via multiple elements? Is it different for unit designs, front, rear, internal?

sound – Can any one identify the cause of the digital distortion that occurs regularly when I play sound on my recording device?

I have a pretty special problem with reading on my device io. Basically, just about every minute, the sound is associated with a hard digital sound
distortion for a few seconds (between 3 and 10). It's easier to hear than explain, so I posted a sample of the sound here.

I am using a Mackie Onyx 1620i with a serial number 003. My computer is a Thinkpad Lenovo X230 with Ubuntu Studio 18.04 LTE. Both are connected via FireWire. It is important to note that my laptop does not have a dedicated Firewire port. I'm using a 2-port removable wired card on my Express port (a StarTech.com 2-Port 1394a ExpressCard). Although I usually only use the Mackie with Ardor 5, this also occurs in other applications.

The problem only occurs when the audio output from the Thinkpad to the Mackie. The audio recording on the laptop is no problem. Although I had some problems with Mackie with other Ubuntu Studio kernels, it currently runs without drivers in virtually all applications and automatically connects to JACK when I plug it in. A few rare occasions have already occurred when the problem did not occur. t happen at all.

Finally, until now, this problem only concerns this system. I frequently use the Mackie with a Macbook Pro and a Mac Mini (via a Firewire to Thunderbolt adapter, nothing less) and reading has never been a problem.

Troubleshooting things I've tried:
– The two Firewire ports on the ExpressPort card
– The two ports on the Mackie
– Different Firewire cables
– The two Ubuntu studio kernels (low latency and regular)
– ALSA and JACK drivers at different sampling frequencies

If anyone has encountered a problem like this or has any leads, I'd love to hear them.

Recording equipment – How to get the old GamePort detected in Windows 10 Pro?

I have an old GamePort interface to use the old gamepads (see the images below), but I do not think it appears in Device Manager or in any other detection program (I will check when I have time). Advices? If it counts, the interface has not been inserted into the slot because my PC is compact. My motherboard is an HP Compaq 8200 SFF computer.
