Alfred is a former Anglo-Saxon (actually Saxon) land-owner who has been reduced to serfdom for swearing to support William the Bastard and then breaking his oath in rebellion. Understandably he’s a bit put out by this.

William (no, not the Bastard; another one) is a Norman lord who has taken over Alfred’s estates. He is a bit of a thicko, and his main strength is bashing people with big lumps of optionally sharpened metal; his language skills aren’t especially pronounced which is somewhat ironic as a Norman is really a Viking with a French accent.

Bruce is William’s sword brother and is currently present so William can utter asides to him during the following dialog; he is presently visiting William as a break from his somewhat grimmer estates in Northumbria near the Scottish border, and to drink as much as is humanly possible.

William: “Oy! Alfred. Bring bœuf”

Alfred looks puzzled; he’s heard the word bœuf before but isn’t sure what it means, and isn’t in the mood to be helpful (he rarely is).

William (in Norman French which I have rendered in English because my Norman French is non-existent, and I’m not sure Google Translate is up to this job. It is also in italics to clarify that William is making an aside to Bruce): “These Saxons are a bit thick; can’t even understand the simplest commands.”

William: “Bring ox(masculine ending)”

Alfred: “We don’t have ox(masculine ending), how about ox(feminine ending)?”

William: “Just bring it”

Alfred leaves the hall looking puzzled, and is gone for an unusually long time.

Bruce: Is he trying to breed with the cow so he can bring a bull?

Alfred arrives back leading a cow on a rope; it is obviously still alive. William stands and starts to draw his sword whereas Bruce hurls his nearly empty tankard at Alfred which fortunately bonks his head. This seems to satisfy William who slumps back down in his chair and mutters: See what I have to put up with?

Alfred: “Did you mean ox(ending indicating a roasted dish)?”

William: “Bring food”

Alfred hands the cow’s rope to another serf, heads out of the hall, and comes back a few minutes later with some roast ox.

I have made the dreadful mistake of having two winter coats. To those who are used to making clothing decisions, this may seem trivial, but I am now in danger of standing in front of the coat pegs trying to decide which one to choose. And just to emphasise that, this post is written because I spent 30s doing exactly that the other day.

Should I choose the sensible coat (which seems to have mysteriously lost girth in the last few years), or do I choose the extreme weather coat? Weather sometimes makes the choice for me, but more often than not it doesn’t. Which one looks better?

Now that is a daft question. I can make myself look “smart” but that comes at the cost of looking like I work for one of the Kray twins (or rather their spiritual descendants). Probably one with an affectionate nickname like “Murder Mike”.

Although that could have something to do with the expression that automatically appears on my face whenever I put on a suit. The kind that causes small children to burst into tears when they see me with it.

On a slightly more serious note, it is worth noting that con-men have also heard the phrase “Clothes maketh the man” and makes use of it.

Or which one is more comfortable? Well in extreme weather, the extreme weather coat of course, but it also quickly becomes too warm. And it’s heavy.

So now I’m stuck with two coats, and if I’m late into work this morning, it’ll be because of the coat choice.

Today I pointed out that persuading teenagers to stop thinking “filthy” thoughts is roughly comparable to the task of emptying the ocean with a teaspoon, and someone retorted that the later was possible. Well perhaps, but until we’ve worked out a rough calculation we don’t really know do we?

And yes I am weird enough to have gone ahead and worked it out.

 

 

Swirling Sea

According to the wonder that is Wikipedia, the average teaspoon can contain approximately 5ml of liquid – not often ocean but the type of liquid is irrelevant.

According to a handy table, there are approximately 1.3 billion square kilometres of water in the world’s oceans. And according to a handy units calculator this equates to 1.3e21 litres of water. Dividing this figure by the volume of our teaspoon, we get the value 2.6e+23 teaspoons of water in the ocean.

Assuming that it takes 10s (we could argue about how accurate that is, but trust me it doesn’t make too much of a difference to the final conclusion) to move a teaspoon of seawater into a truly ginormous container that magically appears to contain it all, it will take approximately 2.6e+24 seconds to empty the oceans.

Now you could work on this non-stop, but I’m no Victorian factory owner, so I will be assuming an 8-hour working day, and a 5 day working week. Admittedly no paid holiday (you want pay for this? I don’t think so).

So dividing the stupendously large number of seconds by 60 (to get minutes) by 60 (to get hours) by 8 (to get days) by 5 (to get weeks) by 52 (to get years) we get approximately 3.5e+17 years. Good! We’ve reduced the E numbers somewhat!

Now if we divide this number of years by the expected lifetime of the sun (10 billion years – and ignoring the fact that we’re approximately half-way through the sun’s lifetime), we get a much more manageable figure of 34,722,222 sun lifetimes.

However it is not unreasonable to assume that something will happen to the oceans before we get anywhere near completing this little task.

(actually we don’t usually sit in the data centre; it’s too noisy and usually the wrong temperature for people)

There is a perception amongst people that security “gurus” who work in network security are spying on all your network traffic. Not the hackers (which is a whole other matter), but the people who run enterprise firewalls. We do, but we’re not interested in what you are doing but instead what is being done to you (and the enterprise as a whole).

Frankly nothing strikes me as more boring than spying on someone’s porn browsing – if I really need to, I’ll hunt down my own porn thank you very much! And we’re busy; you could probably double the size of every network security team in every organisation on the planet and still nobody would be sitting around twiddling their thumbs.

On the subject of porn (as an extreme example), it is not a security issue. There is an argument that browsing porn sites is putting yourself at greater risk of picking up some kind of nasty infection, but avoiding porn sites to avoid getting infected with malware is a tactic that results in your computer being infected. So the intended content isn’t a problem as far as security is concerned, but we’re interested in unintended content.

Now there are places that enforce browsing censorship – blocking anything that isn’t work-related. That role is usually dumped on the network security people because they have the tools to do the job.

Does porn browsing on the office matter? Of course it does – some people are upset by the sight of such things, and almost as important, when someone is browsing porn they are not working. But such matters are best dealt with in the office by the line manager – if someone isn’t doing their work it doesn’t matter if they are browsing porn, hitting Facebook, or snoozing under the desk. All should be dealt with appropriately by the line manager.

And centralised censorship is a rather clumsy tool – blocking Facebook is all very well if it is to prevent personal usage of the Internet, but what about the Marketing department using Facebook for publicity? Or the Customer Service department keeping an eye on Facebook for product problems that they need to look into? These can be allowed through on a case-by-case basis, but it highlights that censorship is a clumsy tool.

The word from a nameless vendor who is in this space, is that in many cases this censorship has less to do with preventing people from doing “naughty” things, and more to do with controlling bandwidth usage. And as bandwidth becomes cheaper, there is less interest in censoring Internet activities – certainly from a personal perspective I notice a decrease in the number of people who complain they cannot visit certain sites because of work’s “firewall”.

There is also the subject of TLS inspection where firewalls intercept and inspect TLS or SSL encrypted traffic between you and “out there”. Again there is a suspicion that we are for whatever reason spying on your activities. The answer to this is the same as previously – why should we bother? It is too much like hard work, and frankly most of the information that passes through a firewall is unbelievably boring.

No, TLS interception is used to do the boring task of inspecting traffic for malware, spyware, and other security threats. And with the increasing use of TLS to encrypt traffic it is becoming more and more important to do TLS interception for security reasons.

Yes there are those who would use that sort of technology to spy on your activities, but those organisations are typically nation states … and repressive ones at that. But it is extreme foolishness to blame a useful tool for the abuses that an abusive government perpetrates.  Your average enterprise just isn’t that interested in what you’re up to.

And if you still don’t believe this, there is a simple answer: Do anything private on your own private network.

(because everyone else has some)

  1. Stay in the shade; the big shiny thing in the sky is the heat source.
  2. If you are in the sun, wear white; it absorbs less of the heat from that big shiny thing. See point#1.
  3. If you are in the shade, wear black; it radiates more heat. See point#1.
