fonts - Can you recommend any information about least ambiguous letters/numbers? -

-

I'm interested in making short codes (up to 6 characters) which are clear for human readability:

A good code would be like this: AE37HT, say.

Obviously, I can try to understand myself, but I was watching that no one was studied by people like NASA or not.

If you are also impressed by seeing the readability color, typeface, size, and distance (I'm potentially seeing something about an inch high from around 6 feet), It will also be useful on the monitor or perhaps even in print.

I have been given these guidelines, but there are no empirical results in it, which I can change in a table to prepare the code:

If your goal is purest clarity, then it will be a matter of choosing that font Which is preferably:

1) To select the fixed width random numbers / letters, there is considerable help in the fixed width, because the kerning is not changing when going across the fern.

2) Use a font with different 0 / o - which are definitely dirty people. See similar letters / number combinations, potentially, leave 0 / O of the mixture for this reason.

3) Choose a font with subtle serif and weight changes.

For some clear directions, see.

With the right font, I think that you can choose any letter / number combination and it can be clearly understood (except maybe 0 and o). I believe 8 / B, 5 / S and other samples will be clarified in the correct font.

The second thing that you can think of will be the use of one color for each letter and numbers - it will potentially cover the unreadable number / letter combinations I will make it a subtle Q, However, if there is a drastic color change, attention will be drawn to letters or numbers, which will harm the overall readability.

After reading your comment on any other answer, edit:

I only need a few thousand codes, so I'm about the size of the domain I am not very worried.

If this is the case, then I recommend leaving the whole number set, and adding only to those letters which do not have any view (or audio) You are reading this) with the similarity of numbers 6 points, even so Connecting with numbers, such as letters to help change you over to have code prospects would be easier to try to remove the selected few. Maybe I'll stick to 1-9, A, Z, R, W and other letters that do not match with numbers.

c++ - Linux and clipboard -

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
