air travel – If I know a flight is delayed can I turn up late for check-in at the airport?

No you can’t turn up late to check-in on a delayed flight, unless the check-in closing time is delayed along with the departure time. Note that usually this is not the case.

The check-in closing time is set relative to the scheduled departure, and usually remains the same, regardless of whether the flight is delayed or not. Hence if you show up at the airport late for check-in, even though you still have plenty of time before boarding due to the flight being delayed, you will be considered as a no-show. This happened to me a few years back on a snowy day in which all inbound and outbound flights to/from LHR were delayed.

Several websites and forums mention this (see here and here). However I believe this webpage from Air Berlin to be more authoritative:

We are unable to check in passengers arriving at the check-in desk after the check-in deadline. These passengers lose their entitlement to be carried on the flight and do not have any right of reimbursement, issue of a credit note or free rebooking. This check-in deadline will remain the same even if the departure of the flight is delayed.

(Emphasis mine)

Other airlines, including Emirates and British Airways, carry no mention of whether the check-in deadline can be modified, probably because they assume that when flights are delayed the check-in closing time does not vary. However they do mention that arriving late for check-in will cause you to be denied boarding in their Terms of Carriage. Emirates (in PDF) says:

6.3 You must comply with the applicable Check-in Deadline. We have the right to cancel your
reservation if you do not comply with the Check-in Deadline or, if no Check-in Deadline has been
indicated, you fail to check-in prior to closing of check-in for your flight. See also Article 5.7.

British Airways says:

6c) You must check in by the check-in deadline

If you do not complete the check-in process by the check-in deadline, we may decide to cancel your reservation and not carry you. By completing the check-in process we mean that you have received your boarding pass for your flight.

Using Arcane Abeyance to cast Fabricate, could you turn an enemy’s plate armor into a full body restraint?

If a player uses a bead with the spell fabricate in it from the Arcane Abeyance feature, could they turn an enemy in plate armor’s armor into an iron maiden or just a full-body metal-binding?

wide angle – Suggest a video camera with an ability to turn off the stabilization

I want to record a video of me playing a guitar where the camera is mounted firmly on the guitar itself. I got quite nice results from using my iPhone 11 pro for that purpose, but there is one issue. When I hit the guitar(to make a percussion kick sound), the stabilisation kick in and as the result the guitar shakes in the video. I don’t care about the shaking of the environment as I record in almost total darkness, but I want the guitar to be steady.
Another criteria is the view angle. As the camera is placed quite near from the guitar, I need to use the 0.5 zoom mode on the iPhone to get the picture I want.

Can you suggest a camera to satisfy my needs?

How to turn off auto zoom in echarts?

I want to display Ekg waves. I use echarts. But there is a small problem with the visualize.

My chart:

enter image description here

But I want to see like this page:
https://www.arction.com/lightningchart-js-interactive-examples/examples/lcjs-example-0150-ecg.html

My code is here:

var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);
var option;

option = {
    title: {
        text: '动态数据 + 时间坐标轴'
    },
    tooltip: {
        trigger: 'axis',
        axisPointer: {
            animation: false
        }
    },
    xAxis: {
        type: 'category',
        splitLine: {
            show: false
        }
    },
    yAxis: {
        type: 'value',
        boundaryGap: (0, '100%'),
        min: -1,
        max: 1,
        splitLine: {
            show: false
        }
    },
    series: ({
        name: '模拟数据',
        type: 'line',
        showSymbol: false,
        hoverAnimation: false,
        data: data
    })
};

setInterval(function () {

    for (var i = 0; i < 5; i++) {
        data.shift();
        data.push(addData());
    }

    myChart.setOption({
        series: ({
            data: data
        })
    });
}, 1000);

option && myChart.setOption(option);

So what do I need to set on the graph to show the whole thing from a distance instead of zooming in on the drawn part?

fastboot – Turn phone on with damaged power & volume button?

if Power and volume button is busted, is it possible to turn phone on by using adb or fastboot or any other method?

Or may be, How a powered off phone communicate with the power button and other things(i.e charging animation,volume button etc)? perhaps is it possible to tweak this communication to gain access externally?

Curious, solving this issue by software means, possible?

matrix – How to turn of the large output suppression

I am currently calculating some large matrix operations.
The calculation results enter image description herein some huge size matrices, and the output is sometimes suppressed as this

However, I really don’t want it to be shown like this, so I click “show all”, then the program stuck forever.

But when the output is just a full matrix, it usually doesn’t have this problem.

How can I make Mathematica show the result without any suppression? Any command to that?

Thank you very much!
