The answer is in *[Numpad in PuTTY while using vi \[Cialug\]][1]*:

&gt; In the configuration, go to Terminal-&gt;Features and check &quot;Disable 
&gt; application keypad mode&quot;. Save the settings and enjoy a numeric pad 
&gt; that works!

I have always used this set of mappings to interpret the escape sequences as numbers when `$TERM=xterm`

    imap &lt;Esc&gt;Oq 1
    imap &lt;Esc&gt;Or 2
    imap &lt;Esc&gt;Os 3
    imap &lt;Esc&gt;Ot 4
    imap &lt;Esc&gt;Ou 5
    imap &lt;Esc&gt;Ov 6
    imap &lt;Esc&gt;Ow 7
    imap &lt;Esc&gt;Ox 8
    imap &lt;Esc&gt;Oy 9
    imap &lt;Esc&gt;Op 0
    imap &lt;Esc&gt;On .
    imap &lt;Esc&gt;OR *
    imap &lt;Esc&gt;OQ /

And for Mac, the answer is in a comment by [HaPsantran][1] on this [same][2] page and there is a similar answer by [nfechner][3] with German screenshots in [this answer][4].

For Mac, go to your **Terminal** application. Select **Preferences**, **Profiles**, **Advanced** and deselect **Allow VT100 application keypad mode**.

If using SSH through a terminal you can just go to 
    
    Edit -&gt; Num Lock (third from bottom)

It needs to have a checkmark to the left of it.


The previous answers [by kirby][1], [michael-berkowski][2], [and pykler][3] are great.

I had this issue in Vim on macOS&#39;s terminal. Checking *Terminal* &amp;rarr; *Preferences* &amp;rarr; *Profiles* &amp;rarr; *Keyboard* showed that *&quot;Clear (Keypad)&quot;* was mapped to *&quot;Num Lock&quot;*. Pressing clear fixed the issue for me.

How come that in the following snippet

    int a = 7;
    int b = 3;
    double c = 0;
    c = a / b;

`c` ends up having the value 2, rather than 2.3333, as one would expect. If `a` and `b` are doubles, the answer does turn to 2.333. But surely because `c`  already is a double it should have worked with integers?

So how come `int/int=double` doesn&#39;t work?


Why does dividing two int not yield the right value when assigned to double?

If I were using an RDBMS (e.g. SQL Server) to store event sourcing data, what might the schema look like? 

I&#39;ve seen a few variations talked about in an abstract sense, but nothing concrete. 

For example, say one has a &quot;Product&quot; entity, and changes to that product could come in the form of: Price, Cost and Description. I&#39;m confused about whether I&#39;d: 

 1. Have a &quot;ProductEvent&quot; table, that has all the fields for a product, where each change means a new record in that table, plus &quot;who, what, where, why, when and how&quot; (WWWWWH) as appropriate. When cost, price or description are changed, a whole new row as added to represent the Product.
 2. Store product Cost, Price and Description in separate tables joined to the Product table with a foreign key relationship. When changes to those properties occur, write new rows with WWWWWH as appropriate.
 3. Store WWWWWH, plus a serialised object representing the event, in a &quot;ProductEvent&quot; table, meaning the event itself must be loaded, de-serialised and re-played in my application code in order to re-build the application state for a given Product.

Particularly I worry about option 2 above. Taken to the extreme, the product table would be almost one-table-per-property, where to load the Application State for a given product would require loading all events for that product from each product event table. This table-explosion smells wrong to me.
 
I&#39;m sure &quot;it depends&quot;, and while there&#39;s no single &quot;correct answer&quot;, I&#39;m trying to get a feel for what is acceptable, and what is totally not acceptable. I&#39;m also aware that NoSQL can help here, where events could be stored against an aggregate root, meaning only a single request to the database to get the events to rebuild the object from, but we&#39;re not using a NoSQL db at the moment so I&#39;m feeling around for alternatives.

I am having a strange issue with iTerm2, in terminal vim (non-gui) and the solarized color scheme. First, I have set iTerm2 to use the dark solarized colour scheme.

I am also using solarized for vim. I have the following lines in my .vimrc

    set background=dark
    colorscheme solarized

In the terminal the color scheme looks incorrect:
![console vim][1]

For reference this is how it looks under MacVim (gui vim)
![gui vim][2]

What do I need to change in iTerm or my .vimrc to get the colors looking correctly in my console vim?

I use VIM pretty regularly now but I never use the dot (.) command to repeat the previous action. I keep reading about how awesome it is but I never see any real world examples that make sense to me and the way I code in VIM. What are some real world examples that show how awesome the dot (.) command is?

Why the dot (.) command is so useful in VIM?

Is there a way to get a list of all installed color schemes in Vim? That would make very easy to select one without looking at the `.vim` directory.

I have been using vim for quite some time and am aware that selecting blocks of text in visual mode is as simple as &lt;kbd&gt;SHIFT&lt;/kbd&gt;+&lt;kbd&gt;V&lt;/kbd&gt; and moving the arrow key up or down line-by-line until I reach the end of the block of text that I want selected.

My question is - is there a faster way in visual mode to select a block of text for example by &lt;kbd&gt;SHIFT&lt;/kbd&gt;+&lt;kbd&gt;V&lt;/kbd&gt; followed by specifying the line number in which I want the selection to stop? (via `:35` for example, where 35 is the line number I want to select up to - this obviously does not work so my question is to find how if something similar to this can be done...)

I tried to map &lt;Alt+D&gt; to &lt;Ctrl+D&gt; as adding the below line to .vimrc, but it doesn&#39;t work. I checked the .vimrc is loaded by Vim.

is there any error in this mapping?

i&#39;m using [Paramiko][1] to connect through ssh to a server.

Basic authentication works well, but i can&#39;t understand how to connect with public key.

When i connect with putty, the server tell me this:

    Using username &quot;root&quot;.
    Authenticating with public key &quot;rsa-key@ddddd.com&quot;
    Passphrase for key &quot;rsa-key@ddddd.com&quot;: [i&#39;ve inserted the passphrase here]
    Last login: Mon Dec  5 09:25:18 2011 from ...

I connect to it with this ppk file:

    PuTTY-User-Key-File-2: ssh-rsa
    Encryption: aes256-cbc
    Comment: rsa-key@dddd.com
    Public-Lines: 4
    [4 lines key]
    Private-Lines: 8
    [8 lines key]
    Private-MAC: [hash]


With basic auth the error i get (from the log) is:

    DEB [20111205-09:48:44.328] thr=1   paramiko.transport: userauth is OK
    DEB [20111205-09:48:44.927] thr=1   paramiko.transport: Authentication type (password) not permitted.

I&#39;ve tried to include that ppk file and set to auth_public_key, but didn&#39;t work.

Can you help me?

Has anyone else ever had this error in PuTTy?

For example, pressing the Up Key now produces:

    &gt;&gt;&gt; ^[[A


Google doesn&#39;t let you search for special characters so I&#39;m stumped at finding existing version of this problem. 

--------------

EDIT:

So this happened after I pasted in some unicode (when, I think, the translation was already set to utf-8). 

I&#39;ve checked the Change Settings dialog box for different settings than my other open PuTTy windows, but the settings appear to be identical. 


EDIT2:

This is fixed by restarting PuTTy, but still a nuisance. 


**EDIT3:**

**How to replicate the exact same bug:**

 1. Open a putty terminal to a linux PC (I&#39;m using RedHat)
 2. Open Python 2.7.*  - using the command `python2.7` (note: error does not appear in 2.6)
 3. `import codecs`
 4. Now use the arrow keys, and these bizarre characters appear.

I&#39;m trying to a get a &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;tab&lt;/kbd&gt; and &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;shift&lt;/kbd&gt;+&lt;kbd&gt;tab&lt;/kbd&gt; binding to work inside of a tmux session (I&#39;m also using PuTTY).

I already went through the pains of having to recompile PuTTY so it would send &lt;kbd&gt;ctrl&lt;/kbd&gt; and &lt;kbd&gt;shift &lt;/kbd&gt; correctly. After using &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;v&lt;/kbd&gt;, and I&#39;m able to see that `^[[27;5;9~` and `^[[27;6;9~` are being sent for &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;tab&lt;/kbd&gt; and &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;shift&lt;/kbd&gt;+&lt;kbd&gt;tab&lt;/kbd&gt;, respectively. Is there any way I can get these bound to next-window and previous-window inside of tmux?

Edit:
After some research, I&#39;m thinking I might have to configure xterm to include those keycodes. Any idea how I would go about doing that?

Edit2:
So I found out I can retrieve infocmp and recompile it. I added

`kctab=\E[27;5;9~, kcstab=\E[27;6;9~,`

to the end of it, except now it&#39;s giving me an error. &quot;**entry does not start with terminal names in column one**&quot;
