## javascript – Find the minimum number of rooms required

The problem statement is as follows

Given a range of time intervals (beginning, end) for class presentations (possibly overlapping ones), determine the minimum number of pieces required.

For example, given ((30, 75), (0, 50), (60, 150)), you must return 2.

This is supposed to be a easy challenge but that was not the case for me.

Here is my solution in JavaScript

``````exports.roomsRequired = function roomsRequired(lectureIntervals) {
function Room() {
return {
busy: ()
};
}

let rooms = ();

lectureIntervals.forEach(lectureInterval => {
let roomFound = false;
rooms.forEach(room => {
let roomBusyInLectureHours = false;
room.busy.forEach(reserved => {
let lectureStart = lectureInterval(0);
let lectureEnd = lectureInterval(1);
let reservedStart = reserved(0);
let reservedEnd = reserved(1);
if (lectureStart > reservedStart && lectureStart < reservedEnd) {
roomBusyInLectureHours = true;
}
if (lectureEnd > reservedStart && lectureEnd < reservedEnd) {
roomBusyInLectureHours = true;
}
});
if (!roomBusyInLectureHours) {
room.busy.push(lectureInterval);
roomFound = true;
}
});
if (!roomFound) {
let room = new Room();
room.busy.push(lectureInterval);
rooms.push(room);
}
});

return rooms;
};
``````

The only test case I have so far

``````let rooms = exports.roomsRequired(((30, 75), (0, 50), (60, 150)));
for (let i = 0; i < rooms.length; i++) {
console.log(rooms(i).busy)
}
``````

What impressions

``````( ( 30, 75 ) )
( ( 0, 50 ), ( 60, 150 ) )
``````

I know that I do not return the number of pieces, but it is essentially the number of rows seen. For example, in the previous case, it is `2` as expected.

My question is: can this code be much shorter? I suspect that I'm missing something obvious being that easy challenge.

The pseudo-code of my implementation would look like this

``````For Each Interval:
For Each Room in Rooms:
For Each IntervalWithinThatRoom:
Check If IntervalWithinThatRoom overlaps with Interval
If No Overlaps Found
Push Interval to Room
If Interval Not pushed to any Room
Create new Room
Push Interval to Room
Push new Room to Rooms
``````

## g Suite Administrator – How can I replace the default Google Calendar settings for users so that they can edit and move meetings between our rooms?

Within our organization, we have four conference rooms currently configured as resources via GSuite for Business.

One of these rooms has become the recruiting / interview room. I would like to give our recruiting team priority access to this room, with the following basic rules:

• If the room is not reserved, any user should be able to book it for an event.
• If the room is reserved for an event, Recruitment should be able to modify the details of the event and move it to another room.
• Other users should not be able to move or edit default events.

We have already configured where the rooms are configured as resources. We have also added calendaring to all rooms where "Make Changes and Manage Sharing" access is enabled. However, while they are able to see events they are not able to move an event in another room.

Someone has thoughts?

## July 2019 Report on the prices of server rooms

This is the fifth installment of the monthly server price reports for 2019. The month of May has been unusually busy.

If you followed, we tracked the price of parts for RAM, SSDs, hard drives, processors and some GPUs. Generally, this is done monthly, then shared with WHT and on our blog.

Currently, all prices listed are those of ebay, for used equipment. I can also start looking for more new material if there is a request.

* This month, we also saw a decrease in almost all the RAM models we followed.

As before, let me know if you have comments, how I can make this more useful, etc.

Some notable changes compared to last month:

* The majority of RAM products still seem to be falling every month this month.

* All processor prices are down, but especially in the high-end E5-v3 (models 2660, 2670 and 2680).

* Some discs, including the 12GB HGST hard drives, offer quite good availability in the brand new disc market, often cheaper than some second-hand discs.

## Airbnb – the host wants to reduce the number of rooms, can we get a refund?

My family must stay in an Airbnb house in the next few days. It is three bedrooms and advertised as having room for us alone. We are two adults and two children (one aged five and one year old). It's a long drive to get there.

The host sent a message this morning and said that he was having trouble giving us the whole house and that he wanted to confine us to a single room that they thought would house us. We presume that since this reservation was made a few weeks ago, they have other paying customers because they want the custom. They also say that they will give us a reduced rate, but that's not the issue.

We are currently trying to get a refund and try to stay elsewhere because we would not want to stay there and be locked in one room (especially with a baby who is teething and has trouble getting sleep, and good 4 hours driving to get there and the next day 4 hours), and would not feel particularly comfortable with other people there anyway. But is it feasible with the rules of Airbnb? I admit that I have only briefly looked at their terms of use.

## Should a man be legally allowed to enter women's washrooms and locker rooms simply by saying that he identifies as a woman if asked?

"should" no longer really matter ….

… because the simple fact is that there is no legal definition of the term "transgender" … and any attempt to legally define gender has been attacked as "fanatic" and presented as having police standing in front of the toilet for "dropping" checks.

"man" and "woman" do not matter anymore … and that was the goal all the time ….

people have been fooled by the remains of 60 years as Jerry Brown whose ideology is that the very concept of "gender" is inherently divisive and implies a "natural" hierarchy … for them, only the 39. Elimination of "gender" as a construction can lead to true equality …

That's why Brown used hysteria about "hate and fanaticism" to prevent people from questioning his act that made the choice of restrooms and locker rooms in all California schools a matter of "d & rsquo; "Identity" individual …

find? schools …. all the way down to the children's gardens …..

how did the social engineers of the 1960s push their agenda? by imposing it in primary schools so that children grow up with a sense of normalcy …

rinse and repeat ….

Here is a quick description of these 3 tables:

• `_Rooms` contains information about rooms that I can rent in my hotel.
• `___Rates` contains information about rates that I can charge for a special period and for rooms (if RAT_RoomsAffected is set to all, it means that the rate can be applied to all rooms in my hotel.) RAT_RoomsAffected is set to list, rate can only be applied to rooms id in the RAT_RoomsList field).
• `___ Availability` list by day the possibility (Open) to reserve this room or the non possibility to reserve a room (Close).

My issue is the following:

I would like to list the rooms that meet the following two conditions:

• This room should be with the `Open` status (AVA_Status) for the dates that a customer wants to book at my hotel. For example, from 2019-04-02 to 2019-04-04 (2 nights).

• These rooms must be linked to a rate in `_Rates` table. So, depending on the client's dates of stay, I have to go through this table and find a rate for that period.

• Finally, the fares found must correspond to `ROO_Id` found in the first step. A `ROO_Id` could match if `RAT_RoomsAffected = all` or when that `ROO_Id` is in the `RAT_RoomsList` listing.

The desired exit should be from 2019-04-02 to 2019-04-04:

``````| -------- | ---------- | ----------- |
| ROO_Id | ROO_Name | RAT_Price |
| -------- | ---------- | ----------- |
| 1 | Blue | 139.00 |
| -------- | ---------- | ----------- |

## February 2019 Report on the prices of server rooms

This is the second installment of the monthly server price report.

I'm sure you've seen the sudden swings in ram prices and SSD last year or so. This can be difficult to follow. In the same vein, I will follow them monthly, and I might as well share my report here. For starters, I am following RAM, SSDs, hard drives, processors and some GPUs.

I have had some feedbacks that it would be nice to track the prices of the new processors. If there are any particular models that you think should be followed, let me know and I'll think about adding them.

Currently, all prices listed are those of ebay, for used equipment. I can also start looking for new material if there is a request.
