Using Chrome on Windows with a different proxy server than the system one (which is used by Internet Explorer)

Posted by jpluimers on 2019/10/25

By default, Chrome uses the same proxy server as Internet Explorer: the system one that your Chrome settings page accesses from chrome://settings/search#proxy through this command-line call:

"C:\Windows\system32\rundll32.exe" C:\Windows\system32\shell32.dll,Control_RunDLL C:\Windows\system32\inetcpl.cpl,,4

There is no GUI way inside Chrome to change this, but there is a command-line parameter: --proxy-server="ipaddress:port"

So create a new shortcut to Chrome, then you can change it.

This comes in very handy if you want to test

  • some sessions through for instance Internet Explorer going through HTTP Fiddler (that defaults at localhost:8888)
  • other sessions through Cntlm (that defaults to localhost:3128)

Some background information:

CSP and bookmarklets

Posted by jpluimers on 2019/10/25

If you find out bookmarklets like the [WayBack] Press-This or [Archive.is] SubToMe do not work on some pages but to on others.

Often it’s not the bookmarklet, but a combination the site disabling CSP (Content Security Policy) and browsers not coping well with that, see for instance:

OpenSuSE: the relation between /etc/var/named.d and /var/lib/named

Posted by jpluimers on 2019/10/24

For first time BIND named users on OpenSuSE there is often confusion on the relation between these directories:

  • /etc/named.d/
  • /var/lib/named/

For example here someone else struggled: [WayBack] Re: Fwd: Re: [opensuse] Split DNS? Solved

This is how I inferred the workings:

The /etc/named.conf.include is re-generated at named start by running /usr/share/bind/createNamedConfInclude by including files that both match NAMED_CONF_INCLUDE_FILES in /etc/sysconfig/named and exist in the /etc/named.d/ directory.

At named startup, it also copies everything from /etc/named.d to /var/lib/named/etc/named.d

For details see

WayBack machine now rate limits your requests and blocks if you go over it

Posted by jpluimers on 2019/10/19

Got this a while ago while saving a bunch of links for my blog; unfortunately the email address did not respond for information

Too Many Requests

We are limiting the number of URLs you can submit to be Archived to the Wayback Machine, using the Save Page Now features, to no more than 15 per minute.

If you submit more than that we will block Save Page Now requests from your IP number for one day.

Please feel free to write to us at info@archive.org if you have questions about this. Please include your IP address and any URLs in the email so we can provide you with better service.

I wish there was a queue service that would make you wait longer, but does fulfill the request.

Reminder to politicians: concrete blocks do not help against trucks

Posted by jpluimers on 2019/10/18

These physics lessens at school were useful after all.

TL;DR:

A concrete block of ~1.500kg will loose against a truck of ~9.000kg, especially if that drives 50 km/hour.

It will not stop the truck, but will start moving by itself in unexpected directions and speeds becoming a projectile by itself or worse: usually pieces break off traveling at quite high speed.

The video below shows what happens.

Beton blocks

Over the last year or so, concrete blocks are deployed in many places of the public areas. The usual deeper motivation is to protect against traffic.

The blocks are put on the ground without anchoring for a variety of motivations like flexibility, ease of deployment/removal, cost of blocks (EUR ~100 each) versus anchoring (EUR ~250 per block) in a non-interconnected way.

Often, the rectangular lego-like blocks with 8 bumps are used which come in two varieties: 40cm high (easier to sit on, look more friendly) of a mere 1200kg or 80cm high (look more massive) of only 2400kg.

Other concrete blocks used are roughly the same dimensions, so an average weight of ~1500kg is reasonable.

Trucks

An average truck (at about 10.000 kg) isn’t a static object. In cities they are usually allowed to drive at 50 km/hour, but during assassination attempts they drove much faster and also were much heavier.

Let’s assume however that a truck used is less heavy (not all bad people are smart to get a really heavy truck) at ~9.000kg.

Truck concrete collision

The assumptions so far: a truck of 9.000kg at 50 km/hour against a concrete block of 1.500kg at standstill.

Even though a collision with a truck looses some energy, a moving truck has a lot of it. So most of the energy from the truck will be partially or fully transferred via its momentum to the concrete block(s).

The physics involved here are about momentum:

  • momentum = mass * velocity
  • momentum in a system is conserved

Before colliding, the truck has momentum, but the concrete block does not. After the collision, the momentum is divided over truck and concrete block so they both have a velocity.

A few cases that can happen, usually in a combined fashion:

  1. The truck comes to a full stop and all momentum is transferred to the block. The block now travels 9.000/1.500 * 50 km/h which is 200 km/h if it was in front of the truck.
  2. If the concrete wasn’t fully in front of the truck, the truck will move in another direction as well as the concrete block. Those directions are hard to predict for the public.
  3. Part of the concrete comes off during collision. Since their weight is smaller, their speed will be higher (because momentum is conserved) and direction even less predictable.
