Welcome
Logitech have at last admitted that their sound-equipment, including the Z-5500 surround sound unit, have very bad shielding:

When the safty went out in my Z-5500 I decided to open it up to investigate, and immediately noticed how ridiculously close the transformer was to the subwoofer speaker.
I decided to try to move the transformer and the humming was reduced so much that I had to place my ear close to the speaker to hear it. Unfortunately the humming is pretty much only reduced in Digital-mode, so some humming seems to be piced up inside the controller unit.
The click and pops are still there too, so I will probably try to shield both the subwoofer and the controller with aluminium foil. I don't know how much that will reduce the clicks and pops but I guess it's worth a try. If you have a better (and cheap) way to do it please leave a comment.
Jag tog tre kort med olika exponeringar 1/60, 1/250 och 1/500. Först försökte jag använda "auto align" i Photoshops HDR-merge men det blev blurrigt som sjutton - jag tog bilderna på frihand mot knät. Bilderna var lite roterade jäntemot varandra så det var lite halvknepigt att få ett hyffsat resultat.
Fördelen med att aligna själv är tydligen också att HDR-mergern inte gissar att det är olika f-stop utan att man istället får specificera vilka exponeringar man använt.
Färgerna blir fantastiska helt klart för att inte tala om detaljgraden på himlen.
Sometimes I've found it useful to limit the speed of form-uploads when debugging java web applications, but haven't found any example code but many that asks for an example. It might be due to the fact that it is so easy to implement when you sit down and think about it. But anyway. Here is one example:
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import java.io.IOException;
/**
* A little filter that makes a pause after every byte transfered, simulating
* a slow internet connection.
*/
public class UploadThrottleFilter implements Filter {
public void init(final FilterConfig filterConfig) throws ServletException {
}
public void doFilter(final ServletRequest servletRequest, final ServletResponse servletResponse, final FilterChain filterChain) throws IOException, ServletException {
final DelayRequestWrapper requestWrapper = new DelayRequestWrapper((HttpServletRequest) servletRequest);
filterChain.doFilter(requestWrapper, servletResponse);
}
public void destroy() {
}
public class DelayRequestWrapper extends HttpServletRequestWrapper {
final private DelayServerInputStream in;
public DelayRequestWrapper(HttpServletRequest request) throws IOException {
super(request);
in = new DelayServerInputStream(request.getInputStream());
}
public ServletInputStream getInputStream() {
return in;
}
}
public static class DelayServerInputStream extends ServletInputStream {
final private ServletInputStream in;
int numOfBytesRead = 0;
public DelayServerInputStream(ServletInputStream inputStream) {
super();
in = inputStream;
}
public int read() throws IOException {
final int chr = in.read();
numOfBytesRead++;
if (numOfBytesRead % 1024 == 0) {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return chr;
}
}
}
En arbetskamrat visade mig sin personliga Google-sida och hur lätt det var att personlisera den och lägga till en massa roliga prylar. Här visar jag hur jag lägger till M.W.s växtakvarieblogg:
Det började komma in lite referer-spammers igen i refererlistan i blogen så det var läge att bygga en finess jag gått och klurat på ett tag.
Den går kortfattat ut på att jag inte registrerar referers förrens en crawler besökt referern och tittat att det faktiskt finns en länk till mig på sidan.
En väldigt häftig referer-spam-bot skulle iofs kunna komma runt det genom att webbservern lyssnar efter mitt ip och publicerar en sida som ser ut att länka till mig. Men det går ju lätt att komma runt genom att låta min crawler använda en slumpmässig anonym proxy.
Laddade även upp den på youtube så får vi se om det genererar någon trafik.
