I have just released GNU Gatekeeper version 5.3.

You can download it from https://www.gnugk.org/h323download.html

This release has a number of new features as well as some important bug
fixes.

Whats new ?

• LRQ loop detection to optimize calls flows between multiple neighbor gatekeepers This new feature has the potential to significantly reduce the load on all gatekeepers and prevent "LRQ storms".
• new routing policy to set call destinations by querying HTTP or REST servers, see [Routing::Http]
• much improved support for SNMP
• important bug fix for TLS encryption of signaling channels
• important bug fixes for H.460.18 NAT traversal (for H.245 tunneling and for multi-homed servers)
• performance optimization: this version can handle 5-10% more proxied  calls on the same hardware
• performance optimization: re-authenticate lightweight, additive registrations only when new aliases differ. This significantly reduces the load on password databases.

Enjoy!

Long Term Life Tips: Top 5 Regrets People Make on their Deathbed:

An astonishing “top 5 list” blog comes to us via longtermtips and I’m pleased to say I’m pretty sure I won’t have any of these regrets when my time inevitably comes.

By Bronnie Ware (who worked for years nursing the dying)

For many years I worked in palliative care. My patients were those who had gone home to die. Some incredibly special times were shared. I was with them for the last three to twelve weeks of their lives.

People grow a lot when they…

Go read. It’s worth it. Then think on it.

… but it seems like what one reader described as “Britain’s patchiest blog”, which you are now reading, is about to be resurrected.

140 characters isn’t enough, and there is plenty I want to say that seems odd in the confines of a closed social network like Facebook or Google+

Interestingly today I was reminded how little importance the “What?” I write and “How?” I write is compared to the “Why?”

This is not an exciting story, despite the title. But it’s true. And it happens to dozens of people every day, and is the reason why getting to work in London can sometimes take so long.

First, let me explain that this is not a story of me causing a fire alarm to go off, for anti-terrorist police to close a station for half an hour, or some dramatic incident that has left TfL seeking an ASBO against me.

This is a story that starts with a strap of a backpack. This strap, in fact:

This morning I caught a tube from Baron’s Court on the District Line heading East. Normally I change at South Kensington for a Circle Line to Moorgate, or hop off at Mansion House and walk up to the office through the City. This morning I had decided to stay on the District line until Blackfriars, and change there for a Circle line. It’s a man’s perogative, etc.

The tube this morning was very busy. During the Olympics it has on the whole been very quiet, but this morning it was the normal 8:15-8:45am peak time crush. I was stood right next to the door at the very front of the train, crushed in by about 20 other souls attempting to share the exact same square foot I was stood on.

At Victoria, as is often the way for the District Line, a lot of hustling and bustling went on as people fought their way out to the platform, and others tried to struggle onto the train. After around a minute, the doors closed.

Except for the one next to me. Looking down, it was jammed on my bag strap.

Swearing, I attempted to free it. It was jammed solid because the hydraulic pressure of the door was pushing against it, but not with sufficient force for the door to close. The guy next to me tried to help. The guy on the platform waiting for the next train also tried to help. Neither of us could free it. Moving it simply led to the door moving along a bit, keeping the strap jammed.

Then the sound of hydraulics releasing was heard, all the doors on the train went to open, and the driver climbed out of the cab. The release of pressure had allowed me to unjam the strap, and recover it into the train. The driver confirmed we were all fine, climbed back into the cab, closed the doors, and off we went.

I apologised to those around me for delaying their journey, even though the total delay was perhaps 60-90 seconds.

Then realised everybody else on the train was delayed, too.

Then a thought about queuing theory and a little knowledge about how loaded that line is with train traffic at that time of the morning hit me: I had delayed tens of thousands of people.

Let me explain how I worked this out.

The District Line is composed of rather large gauge trains. I estimate that conservatively, each train is capable of shifting 2,000 people during peak times. There were certainly at least 2,000 people on my train this morning. Yes, they are only 6 carriages each, but each is certainly capable of holding nearly 350 people, and frequently does. I’m prepared to revise my numbers down if shown evidence.

In addition, the District Line platforms are not just used by the District Line. They’re also used by the Circle line between Gloucester Road and Tower Hill.

A glance at any “passenger information display” on a platform along this part of the network during rush hour will tell you the mean time between trains is 1 minute. There are close to 60 trains an hour going along that piece of track during rush hour.

Because my train was delayed for over a minute, this must have caused the train behind it to be given a red signal. This in turn would have caused the train behind that to be given a red signal, and so on. This buffer effect would be dampened beyond Gloucester Road going West, because the Circle and District lines diverge, giving more time for the red signals to switch to green, meaning scheduled trains would not have to stop in an unscheduled manner.

However, there would have been at least - I think - 5 trains affected by this delay in addition to my own. So we’re now up to 12,000 people in total delayed by my bag strap jamming a door.

It gets worse.

I changed at Blackfriars to a Circle line train. I got off the train I had delayed, waited 60 seconds on the platform and got on the Circle line train immediately following it, obviously now delayed. Cautiously making sure my bag was far from any doors, I boarded aware this train was now at least 2 minutes late against schedule.

Satisfied at the figure I had come up with of around 12,000 delayed passengers, I had assumed I had done no more damage, until we got to Aldgate.

The tube system has a tendency to expect passengers always want to be moving all of the time. Any delay of more than a minute or two at a station is always explained via an announcement. As we sat at Aldgate, the driver announced we were being “regulated” by a red signal. Looking out of the window, I could see an East-bound Metropolitan line train crossing our tracks to head across to East London.

That’s when it hit me. We were “out of position”. The train was a couple of minutes late, and so the guys running the switching had decided to give priority to the Metropolitan Line train, and we were held for approximately 4-5 minutes.

Whilst this part of the Circle line between Aldgate and Tower Hill was not as busy as the District/Circle line Tower Hill back West, a 4 minute delay was enough to ensure that the train behind us was going to be red signalled waiting for us to clear the platform.

That would be enough for the train behind that to be stopped.

And that would be enough for the train behind that to be stopped, which would probably be on the shared part of the network. That would be enough to cascade across the whole part of that line back to Gloucester Road, causing delays to perhaps 12 trains in total.

By now the numbers per carriage were down a little as we were close to the end of peak, but there was probably at least 1,000 people per train out there. Rounding up for the few more probably still around the Victoria area, and we’re up to 25,000 people.

There’s obviously some fudging here - people boarding trains at the “correct time” for them, did not realise the train they were getting was in fact the one after the one they had expected, and they did not suffer any delay. But I also suspect that this effect wasn’t dampened until after the peak ended at around 9:30am, and there were people who boarded their trains at 8:30am or before still out there (it can take 60 minutes easily to get from the “end” of a line into central London), whose journey had taken at least a few minutes longer than normal.

I doubt many noticed. I doubt anybody cares.

But it did make me think about how queueing theory applies to real world problems, and how when TfL moan about people keeping coats, bags and belongings clear of the doors, or jamming the doors to squeeze on rather than wait 6 more minutes for the next train, that they might have a point.

If you cause a train to be delayed, you are not simply inconveniencing the dozen or so people glaring at you in your vicinity. Or the people on the rest of the train who would glare at you if they could. But in fact, you have a cascade effect down the rest of the network. Tens of thousands of people delayed, because you didn’t want to wait 5 minutes. Or because you didn’t keep an eye on your belongings near the door.

I’ll certainly be more careful in future.

The next time I’m sat waiting for a signal to clear or am told that we are “being regulated”, I’ll wonder about whose bag or foot was to blame, and how the numbers of people flowing through London make butterflies flapping their wings on the network capable of huge cascading effects on transport infrastructure.

I love knowing what my friends and family are up to. I love finding out about the latest thoughts going on within my peer groups. I enjoy reading many blogs, newsletter and emails. I used to regularly get over 400 emails a day including group/mailing list traffic, followed over a thousand people on Twitter and was friends with more than 250 people on Facebook. I subscribed to over 200 blogs. I read all of it, all the time.

Mix in LinkedIn, reddit, Hacker News and a few other corners of the web, and we’re suddenly talking about a lot of data flowing into my head.

I’m led to believe that some even value the contributions I make myself from time to time.

However, I’m about to start dialling all that down. I’ve made a start in some places, but over time I’m going to stop reading anywhere near as much short-form (twitter, Facebook, etc.), a little less medium-long form (blogs), and use the time to start reading longer form work again (books) and creating more.

The reason is not because of burn-out, cynicism or some other excuse: I’m not arguing that it’s all pointless, and I’m not being a Luddite. I just want to create more, and there are only so many hours in the day.

This was prompted by going back over my resolutions posted here in December, and realising I’ve made little progress:

• I need to get my weight down. I’m finally prepared to do something about it.

• I want to create more, so will aim to not go more than two or three consecutive days without working on something creative in 2012. It could be writing (here, for example), it could be code for a personal project, or it could be something I’ve never really tried before (music? art? Don’t know yet). I basically want to spend less time reading/consuming and more time doing stuff. David Tate provides excellent inspirationif you want to consider doing the same. I’ll try to document as much of that as possible here.

• I’m going to try and shift from always being behind/late for almost everything going on in my life, to being early. I don’t know how I’m going to do this, but I suspect if I can pull it off, I’ll be calmer and happier as a result.

This, I am happy to report, seems to have actually happened for the most part. Public transport not withstanding - including my own self-sabotage - I tend to be where I need to be on-time (or early), far more than I was last year.

Back to the main point: by reading what’s going on out there, by trying out new apps, by listening to all these voices, I am feeling engaged and plugged in, but only as a consumer. The purpose of the Internet is not to simply consume but to create, amend, edit, destroy, vandalise and promote. Ideas, content, products, whatever.

Also, am I the only one who has noticed how exhausting this hosepipe of information can be on a daily - even hourly - basis? I’m tired of consuming. It’s worse than television - at least with television an editor or commissioner has attempted to do some curation.

So I’m not departing, I’m not shutting down accounts, I’m just going to read a great deal less online, to the point the relevant apps might disappear off my phone. In return, I should be able to produce a few new things to share. Watch this space!

In a surprising turn of events, the Brazilian government has found a new ally in its fight against inflation and energy challenges: online casinos and crash games, like Aviator operators. By introducing additional taxes on these rapidly growing sectors, the government aims to channel the revenue into critical areas of the economy, including the burgeoning green energy sector. This strategy not only addresses economic stability but also aligns with Brazil's long-term commitment to sustainable development.

Recently, a significant reserve of oil and gas was discovered in Pakistan’s territorial waters. This finding came after a three-year geographical survey conducted in collaboration with a friendly country. The identification of these reserves could mark an important milestone for Pakistan’s economy. The discovery was confirmed by a detailed study that mapped the exact location of the deposits. The reserves found are considered substantial and have the potential to transform Pakistan’s economy, which currently faces significant financial challenges. The exploitation of these reserves could provide a new source of revenue and reduce the country’s dependence on energy imports. Energy sector experts highlight that, although the discovery is promising, it is still in the early stages of exploration. Considerable investments in infrastructure and technology will be needed to efficiently extract and process the oil and gas. Additionally, the sustainable management of these resources will be crucial to ensure that the economic benefits are long-lasting. The Pakistani government has already been informed about the discovery and is taking steps to initiate exploration activities. The expectation is that, over time, these reserves could significantly contribute to the country’s economic growth, creating jobs and boosting industrial development.

Awesome

A blast to ride

Shame about the engine cutting out down steep hills

Wish Suzuki still made UJM styled shaft drive bikes; not everyone wants a Harley

Would buy again!

What an amazing machine

Great if the weather is pleasant

Good bike for women or men

More than an absolute beginner should get, but so well designed that only an idiot can mess it up

My choice

A true UJM - this bike is a jack of all trades, allowing for many riding styles
