I am outside the Bank of England at this protest against banking fiasco. Change finance now. Better banks, not food banks are some of the slogans around me. The shadow Chancellor John McDonald is due to speak shortly. There are around 100 people here and speakers talking about the effect of austerity on the country triggered by the financial crisis. We got sold out. My name is Rachel Oliver and I'm the head of campaigns and organising at Positive Money. Austerity was a political choice and it was a completely misguided choice. Our politicians cynically told us we're all in it together after the political crisis but then they bailed the banks out with hundreds of billions of pounds of public money and then they slashed billions of pounds from our schools and our hospitals. People are fed up of one rule for the bankers and another for the rest of us. Enough is enough and our politicians need to make real reforms to the system that cause the crash. It makes me angry and I see tremendous social problems arising. Poor people are getting poorer, banks and rich people are getting richer and this is very undesirable. It makes me angry to see it.  So I work part-time so I earn about a bit of a fasten pound a month and you can imagine paying rent and transport in London. That wipes out most of what I earn. Everybody I know is budgeting for their food and we're in work and we're not having to be responsible for families or anything like that. The kind of idea of having any kind of stability, having the ability to raise children in comfort just seems like a far off dream to think how a couple of financial decisions 10 years ago have impacted my life. It's quite dazzling to think about it. It is a disgrace that the City of London now has become the money laundering capital of the world. We will address the issue of money laundering.


Hello everyone. Thanks for having me. This is Alhazane and I want to engineer working forward to TROPAC. Today, I would like to show you my experience in preparing for and taking the all-new Prometheus Certified Associate Certification exam. The Prometheus Certified Associate Certification, as defined by the CNCR, is a pre-professional certification designed for an engineer or application developer with a special interest in observability and monitoring. The main areas the exam covers are the following, observability concepts, Prometheus fundamentals, PROMQL, instrumentation and exporters, alluring and dashboarding. Why should I prepare and take this exam? Well, there are good reasons for that. I think it strengthens the foundation and it motivates to delve deeper into learning more about the cloud-native monitoring ecosystem, besides getting a level of credibility under the belt. So this is where it all started, the opening remark skin-out announcements on Europe 2022. Following my interest registration, I was invited to take online proctor multiple choice Prometheus Certified Associate Vietta exam in July. Now, figuring out where to start could be daunting. Following a proper curriculum eliminates most of the trepidation that comes along with learning a new skill, as it helps to not miss any of the core concepts. As I prepared for the exam, I created a publicly accessible repository on GitHub, where I have linked curator resources to each of the exam's topics, mainly from the official thought-outs, documentation of Prometheus itself, in addition to some excerpts of the Prometheus upper-running book by Breanna Brazil. Before starting with Prometheus, it's worth getting more acquainted with the observatory concepts and terminology, such as metrics, service discovery, and the service-level objective to name a few. Prometheus, beyond doubts, is a major pillar of the cloud-native stacks. This is certainly not Prometheus in two minutes, but it's more of an overview of the Prometheus ecosystem, what capabilities it has, and what to use each for. The Prometheus server components are their trivial components that scrapes metrics from endpoints offered by the discovered targets, the time-serious database where the metrics data gets stored, and the Prometheus HTTP server that offers a rest endpoint along other systems to query metrics data. Regarding instrumentation, Prometheus scrapes metrics from instrumented jobs, either directly or via an intermediary push-get way for short-lived jobs. To collect application-specific metrics, a client library needs to be added to instrument the code in various programming languages. To instrument a third-party system, an exporter can be installed on the host server or next to an application. Another aspect is alerting. Prometheus alert manager is capable of routing alerts to different channels, such as email or Slack. For data visualization, Grafana can be used. Additionally, Prometheus remote write, which is basically sending data to other systems like a warm-term storage. And this is where Thanos, for instance, comes into the picture. If you haven't been working with Prometheus for some time now, I would recommend taking any getting started course, or you can also watch Prometheus' introduction at KubeCon Europe 2020 by Julius Volz, the co-creator of Prometheus. As for Prometheus, it amounts to more than one-fourth of the exam questions, hence the increased importance of knowing how to use it properly, also beyond the exam. Here's an example of a query to get error ratio of an HTTP server for the last 10 minutes. I shout out to Chrome Labs for the ChromeKill cheat sheet. Needless to say, this is not to be memorized, but it does help to get more familiar with the query structure. And last but not least, alerting and dashboarding. Open source tools like Grafana bring life to data through intuitive visualizations of different metrics being monitored. Grafana makes it feasible to see the current state or collected metrics as a graphical representation and to create custom dashboards. Monitoring is often paired with alerting tools that notify engineers when metrics have exceeded or fallen below certain thresholds, specified in accordance with the service level objectives. A tool like Prometheus' alert manager can be used for this purpose, and also it gives ways to filter alerts before sending notifications. So what happens after taking the exam? There is also the exam will be emailed to the exam taker within 24 hours after taking the exam, and if passed, a certification and a badge will be issued. How cool is that? I received the results about five weeks after taking the exam as to as a data one. That is no longer the case as the exam was made generally available last month. I hope you find the information and the resources useful, and I wish you all a great and fruitful KubeCon. Thank you.


Today is the day for the Pride Parade for Portland 2015. We're going to see about 10 floats. We're going to see a lot of walking groups, a lot of church groups. The Portland Bookmobile is going to be in the parade and a lot of music. The crowd is usually in the thousands, close to 10,000 for the whole day and probably about 500 people in the parade this year. The purpose of Pride is just to get together, show that we're here and help the community. It's evolved from a very small, small parade of festival, one day to 10 days of events, with 25 events going on. It takes an entire year. After we get done here this week, we take a few weeks off and start planning for next year. My involvement is I'm on the parade team and I do photography for the entire event. The volunteers are all in the yellow vest this year, so we have about 150 to 200 volunteers. It takes a lot of people to carry the flag and the monitors and do all the fun stuff. On the platform today, we have some celebrity judges. They're judging the floats, the walking teams, and doing commentaries, so everybody knows who they are and what group they're in. The judges judge the different walking teams, the different floats, the handout awards at the festival later on. The big one is always from Wild Burritos, the restaurant. They planned this for about eight months. And we have somebody getting proposed to today.  Two people know about. There's going to be something happening right here. Catch this blue. Take the stage, please. The highlight of the parade every year is the 900 foot flag handmade by a bunch of guys at Blackstones and cost well over 10,000. And it goes 900 feet. It's 24 feet wide. And it's just amazing. So that is truly the spirit of pride. What happens after the parade, we all meet in Deering Oaks. That's where the parade ends. And then there's a four-hour festival with comedians, singers, family areas, beer garden, a little bit of everything for everybody. If people want to get involved, you can go to prideportland.org. We plan all year long so you can get involved in any of the teams.
