php - Update records once a year, spread evenly throughout year -

-

Not the best way to make sure what I'm trying to do, bear with me I Working with PHP with MySQL database

I have a database of 10,000 records, suppose I want to update 10000/365 per day throughout the year. Each record gets updated 1x per year, and spreads well throughout the year.

An easy way to do this is to choose all the records, for each, if ID% 365 = $ day_of_year, then update that record. I'm not worried about leap year.

Is there any way that I can select records from the database rather than selecting all databases and looping through each (approximately 27)? This is a cron job that I will run in the middle of the night, so perhaps this is an important issue. Even then, it bugs me that I have to force my power through 10,000 rupees, it would be nice to find a more beautiful solution by dragging only a small fraction.

add a column

then add that event once a year Moves and reset the values ​​of that column and it is counted in new form - 10000 records of the year are spread out.

Then add another event that runs every night to update the record for the day.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
