How I was affected by a mobile network outage of whom I'm not a subscriber

Today the Swedish mobile network provider 3 had a power failure/outage at a central DC in Stockholm that lasted some ~6 hours. Service over the entire country was affected, although information at this point is a bit sketchy.

This made me think about how a greenfield LTE network could be done today, to do away with all the unnecessary boxes that legacy mobile network's are so riddled with.

Essentially, …

In contact with the Swedish Migration Board, Migrationsverket, recently.  Astounded by some of how their work is done.  While spending time in the customer service phone queue, I took the time to send them two suggestions, of different sort.

The first one has to do with the actual PBX itself:

tips på förbättring av telefonväxeln:
Vid kö, informera i vänte-loopen, där bara "Det är fortfarande samtal före, …

Stumbled upon a pretty interesting pci-e patch to the linux-kernel: https://patchwork.kernel.org/patch/993032/

By default, Linux (pre this patch), configures the Maximum Payload Size for a PCI-e tree according to the lowest MPS of any device connected.

In Jon's words:

pktgen, the packet generator as a kernel module, created by friend Robert Olsson at SLU in Uppsala, is configured according to http://www.linuxfoundation.org/collaborate/workgroups/networking/pktgen.
It's performance depends on a variety of factors, including clone_skb and delay. I found clone_skb, which Robert's examples has at 100000 or so, to perform worse than clone_skb at 0, …

I'm working late doing some sysadmin stuff. Should have this cleaned up until tomorrow when the day-people arrive. :)

100+ core CPU:s

As we stand before 100+ -core CPU:s where shared memory in hardware won't be doable, message passing programming models are required.

All software that wants to be either reliable, robust and/or scalable will have to employ some form of MPI. Even though Intel's "SCC" might provide "software-based coherent shared memory", there should be little doubt that programs and algorithms adapted for MPI, …

At Chalmers Studentbostäder [CSB] we use 10Gbps-grade Linux BGP routers.

In fact, at [CSB] we've been using Linux routers since the networks' inception 1996.

I just did a 'git pull' to update myself on the current state-of-the-art of the Linux network stack in terms of current issues, recently resolved issues for performance, current forwarding records, etc.

This post is mostly a summary of the URL:s I read. I upload all presentations, etc, so that I save a copy of them. …

During my update summarizing work on the recent developments in the Linux Network code, I came across a presentation given by James Bottomley, Novell at the Japan Linux Symposium, Tokyo, 2009, that touches on the subject of why it makes economic sense to contribute to the Linux kernel. And why and how to make "management" understand this. …

The 224 team have added a feature to embed Google Wave's on Confluence pages.

Link to article: http://ffeathers.wordpress.com/2009/11/01/google-wave-in-confluence-wiki-pages/

It would be very useful to be able to email Confluence (via en email account) and have it create new blog entries and possibly more.

This way it is very easy to keep blog updated, BCC it or similar when an interesting email is posted to a mailing-list, etcetera.

I've found these resources on the topic:

• Confluence new feature discussion (starting 2004 !) - http://confluence.atlassian.com/display/DISC/Email+Integration
• Confluence new feature request - http://jira.atlassian. …

I currently have a blog, sort of, at http://blog.martin.millnert.se/. I host it myself at my own Xen machine park. I recently received news from Google that the FTP publishing method that I use with the Blogger blog thingy, would cease to be available: http://blogger-ftp.blogspot.com/

Since I prefer to host my own content, I've decided to migrate the blog to the Confluence I set up a while ago.

I was also planning to this week, …

On the similarities between the Soviet Union and the European Union and how the latter must fail just as the first.

Something has been bothering me in the back of my head for some time. I see bureaucracy and political eliteness and corruption on the rise, and an ever-ongoing dismantling of what used to be called democracy. The political governing in Europe, law making in particular, seems to be more and more disconnected from reality.

These are not new observations, …

Apparently, another war is about to be launched by the US, on Iran.
What I am wondering is not actually whether or not this has anything to do with giving the presidency to McCain, but whether or not it actually matters which one of them wins.

The very best bet conceivable on a possible 'saving' of the world, seems to me to be, given the policies the powers that be continue to pursue (economic growth through destruction....), their inevitable failure. As the rational, …

The past week I've spent some time reading economic articles again.

First, one I'd read before: The Proposed Iranian Oil Bourse (Krassimir Petrov, 2006)
It contains a brief introduction to how the American Empire came about and ends with some methods it might attempt to employ in order to stop the oil bourse, which as far as I am aware, to date still has not come about. I believe the world will be made very well aware of when it goes operational, …

So, this is just a brain dump... the red string might be hard to catch (I doubt there even is one.). I suppose this posts and postings like it are to be regretful once you apply for a job somewhere and people believe you're a terrorist or extremist or whatever... then again, you're probably better of not working for such ignorant, non-interested people anway. :)

US banks are already going bust, but are kept on extended life support right now...
