what I want to make sure is that if mplayer chrashes or ends of any reason, it gets automatically restarted. I therefore have a cron job running every minute which also is a bash script:

Since my programming skills are quite rudimentary, I would greatly appreciate any (easy-to-implement) solutions.

My problem is that each iteration of the loop is very slow. The problem is the MySQL. I was wondering if it was possible to put some kind of wrapper in the while loop to make it fetch more than one record at a time, at the same time, fetching all records into memory is not practical either. I am not worried about the efficiency of the code(hashref vs arrayref,etc..). Rather, I am interested in fetching lets say 10000 records at a time.
The database has ~5 Million records. I can not change/upgrade the server.

a d 0.2000000 b.d.b.d.a.d
b d 0.5000000 b.d.a.d.b.d
In the above result the same rows (which represent connections) are selected multiple times (e.g. b,d; b,c; a,d...) although from the last column which represents the string already contains the combination of characters and therefore the connection should not be selected: in the first row string b.d is created and in the fourth row the same string is concatenated even though CAHRINDEX('b.d', Path) shouldn't be equal to zero.
Does anyone know how to modify the query statement above in order not to select same connections multiple times?

I am not exactly sure what the best solution would be for this problem, but
I have a VPS with 3 ips. I have a unix system behind a home router with no ports forwarded. I want to be able to access myVPSIP:25566 and get the data on the internal system.

How do I go about doing this, I have tried reverse tunneling. If the minecraft server part causes confusion, here is an alternate example that will accomplish the same task.
I have a web server on a computer inside a home network. It cannot get incoming connections, so I purchased a VPS, and it has an IP. I wish to be able to access the web server via the VPS IP. I have tried reverse SSH Tunnel, but am unsure why it does not work.

The goal is a tool-tip with rounded corners and other specific features to replace the default Windows tool tip.
Ideally the tool tip could be antialiased and blended into the backdrop, however at a pinch I could tolerate an aliased boundary. This may also be necessary as the control will often be covering a control with an OpenGL overlay and the whole blending procedure may end up a nightmare.
I have created a custom user control, a persistent instance of which belonds to my applications's main form, overriding the OnPaint and OnPaintBackground methods. The application of transparency however is challenging. As I understand, the graphics object passed to the paint method starts with a copy of the current VisibleClipBounds, where generally the first move is to clear the control with a solid colour and start drawing the main features. My first thought was to bypass the fill and start drawing on the captured background. For the first redraw this works fine, but subsequent redraws keep the previous content instead of re-capturing the backdrop. I hoped that CopyFromScreen would specifically eliminate the currently drawing control from its capture so as to start from a clean base but this is not the case, it captures the rectangle of the new location including the image of the previous location if it is in the bounds.
Other solutions and permutations thereof such as
SetStyle(ControlStyles.SupportsTransparentBackColor, True)
Me.BackColor = Color.Transparent
e.Graphics.Clear(Color.FromArgb(0,0,0,0))
have to-date yielded no appropriate results.
I started with a transparent form using the transparent key colour. This worked with aliasing but using a form as a tool tip seemed excessive and caused annoying artifacts (some of which could be overcome) such as the temporary presence of the taskbar button, focus loss of underlying form with subsequent visual feedback in the host form's title bar colour. The control is much lighter weight but I am struggling to make it work even as well as the form.
At this point I simply ask how to achieve the desired result and whether CopyFromScreen is a part of that solution. | vb.net | winforms | transparency | alpha-transparency | null | null | open | (How c| C)an I use Graphics.CopyFromScreen to enable alpha transparent controls?
