Visualizing mpeg4 motion compensation vectors using mplayer

Visualizing mpeg4 motion compensation vectors using mplayer
The MPEG4 video encoding process makes use of block motion compensation to achieve compression. The motion compensation process serves to produce the intra frames which are the frames between keyframes. I’ve always been fascinated by this process and was delighted to find out that my favorite video player, mplayer, allows one to visualize this process.

Erfunden im Krieg (Moderne Wunder)

Erfunden im Krieg
Haben Sie heute Morgen, als Sie sich fertig gemacht haben, um zur Arbeit zu gehen, einen Moment innegehalten und nachgedacht, wie stark Ihr Leben bisher von Krieg beeinflusst wurde Aller Wahrscheinlichkeit nach nicht. Die USA waren seit über 50 Jahren nicht mehr in einen Weltkrieg verwickelt. Dennoch haben unzählige Dinge des täglichen Gebrauchs ihren Ursprung in Erfindungen, die ursprünglich für kriegerische Einsätze vorgesehen waren - von Haarbürsten bis hin zur Mikrowelle. Auf der einen Seite bringt Krieg schreckliche Massaker, Krankheiten und Leiden. Auf der anderen Seite hat er einige der größten Erfindungen ermöglicht, die die Welt je gesehen hat. Forschungs- und Entwicklungsarbeit für Rüstungszwecke hat nicht nur das Kommunikations- und Transportwesen, sondern auch die Medizin revolutioniert. Sie hat Erfindungen hervorgebracht, die der Menschheit zugute kommen und sich für den alltäglichen Gebrauch eignen. In Kriegszeiten ziehen alle an einem Strang und arbeiten auf ein gemeinsames Ziel hin, wissenschaftliche Ziele stehen über Konkurrenzdenken, und finanzielle Mittel und Personal stehen in Hülle und Fülle zur Verfügung. Einige Erfindungen werden aus der Not geboren, wie beispielweise Margerine aufgrund der Nahrungsmittelknappheit an der Heimatfront. Einige stammen direkt von zerstörenden Waffensystemen ab (Atomkraft), andere wiederum von Verteidigungstechnik (Mikrowelle). Die Ironie des Krieges ist, dass die gleiche Wissenschaft, die zum Töten Abertausender von Menschen erfunden wurde, heute eingesetzt wird, um Leben zu retten. Vom Handy bis zum Haarspray - der Bezug zum Krieg ist in unserem täglichen Leben allgegenwärtig. ‘Erfunden im Krieg’ verfolgt einen Tag im Leben einer ganz normalen Frau und untersucht, inwieweit ihr Leben von Kriegserfindungen beeinflusst wird.

Display BGP routes originated in the local AS

The easiest way to display BGP routes originating in the local autonomous system is to use the regular expression ^$ (empty AS-path) in the show ip bgp regexp command, for example:

PE-A#show ip bgp regexp ^$
BGP table version is 10, local
router ID is 10.0.1.1
Status codes: s suppressed, d damped, h history,
* valid, > best, i - internal,
              r RIB-failure, S
Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network
Next Hop            Metric LocPrf Weight Path
*> 10.0.1.1/32
0.0.0.0                  0         32768 i
r>i10.0.1.2/32
10.0.1.2                 0    100      0 i

If you want to apply a show filter to the printout of this command, you have to use the quote-regexp variant; otherwise the rest of the line is interpreted as regular expression. To skip the header explaining the BGP status code (we know them by heart by now, don’t we?), use …

PE-A#show ip bgp
quote-regexp "^$"  begin Network

Network          Next Hop            Metric LocPrf Weight Path
*>
10.0.1.1/32      0.0.0.0                  0         32768
i
r>i10.0.1.2/32      10.0.1.2                 0    100      0
i

… and end with the eye candy – define this command as an alias: alias exec localbgp show ip bgp quote-regexp "^$" begin Network.

Use the explicit "address-family ipv4" in BGP configurations

If you use multiprotocol BGP (MP-BGP) in your network to support MPLS VPN, IPv6 or IP Multicast over BGP, it's best if you go all the way and configure an explicit ipv4 address family; the resulting BGP configuration is significantly easier to read and understand as the session-specific parameters are clearly separated from the routing-specific parameters and the IPv4 settings are nicely grouped in an explicit section.
To change the format of the BGP configuration, configure the IPv4 address family with the address-family ipv4 unicast router configuration command (the neighbor statements and other configuration settings pertinent to IPv4 configuration are automatically moved into the new address family) or manually activate a BGP neighbor for IPv4 route exchange with the neighbor activate router configuration command.To illustrate the differences between the traditional BGP configuration and the per-address-family configuration, consider a simple MPLS VPN+Internet setup. First the traditional approach:

router bgp 65000
 template peer-policy Internal

send-community both
 exit-peer-policy
 !
 template peer-session
Internal
  remote-as 65000
  update-source Loopback0

exit-peer-session
 !
 no synchronization
 bgp
log-neighbor-changes
 network 10.0.1.1 mask 255.255.255.255

neighbor 10.0.1.5 inherit peer-session Internal
 neighbor 10.0.1.5
description PE-C(RR)
 neighbor 10.0.1.5 inherit peer-policy
Internal
 no auto-summary
 !
 address-family vpnv4
  neighbor
10.0.1.5 activate
  neighbor 10.0.1.5 send-community extended

exit-address-family

... and the changed configuration after the address-family ipv4 command has been entered:

router bgp
65000
 template peer-policy Internal
  send-community both

exit-peer-policy
 !
 template peer-policy InternalV6

send-label
  inherit peer-policy Internal 1
 exit-peer-policy

!
 template peer-session Internal
  remote-as 65000

update-source Loopback0
 exit-peer-session
 !
 bgp
log-neighbor-changes
 neighbor 10.0.1.5 inherit peer-session
Internal
 neighbor 10.0.1.5 description PE-C(RR)
 !

address-family ipv4
  no synchronization
  network 10.0.1.1 mask
255.255.255.255
  neighbor 10.0.1.5 activate
  neighbor 10.0.1.5
inherit peer-policy Internal
  no auto-summary

exit-address-family
 !
 address-family vpnv4
  neighbor 10.0.1.5
activate
  neighbor 10.0.1.5 send-community extended

exit-address-family

PartnerBar: Google's feed aggregating magic javascript widget thingy

I was browsing the Google AJAX Search API blog recently when I discovered they were using an interesting widget at the bottom of the page, it turned out to be PartnerBar. PartnerBar was created as an example for the Google AJAX Feed API. I have been very busy with family stuff recently so I managed to completely miss this when news of it first broke in December (Ajax Feed Partner Bar and The PartnerBar - Contextual Cross Linking). In my defence this is easy to miss, it is called "PartnerBar", which means nothing to anybody on this side of the pond and the launch article talks about "contextual cross linking" (meaningless technobabble!). Essentially, PartnerBar is a feed aggregating magic javascript widget thingy, if it had been launched as such I would have spotted it sooner.

AnywayI have been playing with it recently and have made some minor tweaks to improve it for my own usage, I'm very happy with the results. I can't decide whether to install the resulting widget permanently on my blog because I think people would find it annoying if I were to place it somewhere prominent.

My tweaks and modifications

Feed titles and links.

In the instance of PartnerBar on their blog, Google store an array of their blogs in a JavaScript file: http://www.google.com/uds/solutions/partnerbar/google-blogs.js.

Incidentally, notice how it supports tags so that you can use the same array for multiple widgets with distinct content.

My first modification was to tweak the code so that I did not have to supply the feed name and link, this information is stored in the feed (why store it twice?). To achieve this I overrode the loadPartner method - I think the trick with overriding methods in JavaScript is to make sure the method you override is a small one!

My array of blogs looks like this: blogs.js

Alternating row colours

Secondly, I wanted the feed entries to display in alternating colours. Again, I found a small JavaScript method in PartnerBar (resetClassOnPartnerDom) and overrode it (AFAIK there is no "super" keyword in JavaScript, which is a shame). In order to do this I made use of a getElementsByClassName method that I found on the web.

Final result

You should be able to see the widget in action at the top of this blog entry. However, you can link out to see the final result in standalone glory here.

Hereis my final JavaScript which my customised widget uses: partnerBar.js.

Design

Although I suffer with CSS, I am not a graphic designer and so I tend to steal gather inspiration from elsewhere. I based my widget on the Infected table theme from the CSS table gallery.
