This presentation gives an overview of the different types of profiling available in Go via the runtime/pprof package, and provides a brief look at the possible future for profiling in Go1.9 and later.
We often find ourselves confounded by the fundamentals when it comes to implementing our own proxy. A Proxy can solve much more than a basic use case, and I will be elaborating on the various scenarios where proxies come in handy and will be speaking about the richness of Golang’s httputil package.

This talk was presented at PHP Usergroup Düsseldorf, in January 2012
Even though Python allows many ways to easily debug and profile your code, it is not uncommon to see people overusing simple print statements for this. The presentation will provide an overview of the most common basic debugging techniques that every Python programmer should know. Additionally, for debugging speed or memory problems, couple profilers are presented. Outline:
Basic techniques (print statements, logging)
Debuggers (pdb, winpdb/rpdb2)
Profiling (cProfile, guppy, ...)
This presentation was given at the Linux Open Administration Days in Antwerpen, Belgium. It covers how puppetmanaged.org, a set of common puppet modules can be implemented in any current existing puppet setup.

Python is a great programming language. It is a complete tutorial of using this programming language.
This slides is split into two parts, and it is the first part. Another part is at: http://www.slideshare.net/moskytw/programming-with-python-adv.
This talk is about why I believe having the ability to write tools and/or scripts can help elevate a Pen Testers game to the next level.
The talk is case study driven by the different scenarios I've encountered on assessments and the scripts or tools that have been developed as a result.
Buildout: creating and deploying repeatable applications in pythonCodeSyntax
We use buildout to deploy and create our python applications based on Plone or django.
This presentation explains the source of our work, the past and how and why we use buildout.
This presentation was used at PySS 14 conference in Donostia - San Sebastian
Presentation from the 4th Athens Gophers Meetup.
At a glance we present:
- why we introduced a new language in the organization and why that
was Go
- how we approached the transition
- some of the projects we built in Go

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

3. So, let’s talk about pprof
● Been around since before Go1 was released
● Initial support for CPU and heap profiling
● Full list of default profiles as of Go1.8:
○ CPU
○ Goroutine
○ Heap
○ ThreadCreate
○ Block
○ Mutex (New in Go1.8!)
● Godoc here: https://golang.org/pkg/runtime/pprof/
4. How do I use pprof?
● https://play.golang.org/p/FvEMZw0GhD
● Alternative: import “net/http/pprof”
○ Demo1
5. How do I use pprof? (cont.)
● Use ‘go tool pprof’ to fetch profiles from a program with a pprof server:
● Can also use write profiles when running ‘go test’
○ ex: go test -cpuprofile=cpu.out; go tool pprof presentation.test cpu.out
8. Types of Profiles: Heap
● 4 different modes to view
○ --inuse_space (default): shows live heap memory in bytes
○ --inuse_objects: shows # of live heap objects
○ --alloc_objects: shows # of allocated objects
○ --alloc_space: shows allocated bytes over time
9. Types of Profiles: Goroutine
● List goroutines aggregated by stack
● Use debug=2 to have all routines separated, with current state included.
10. Types of Profiles: ThreadCreate
● Shows which goroutines lead to creation of threads in an app
○ Broken? See https://github.com/golang/go/issues/6104
11. Types of Profiles: Block
● Shows time spent blocked on synchronization (mutexes, channels, etc.)
● Not enabled by default call runtime.SetBlockProfileRate() to enable
○ Argument is rate in ns to sample blocked routines
○ 1 = sample all events
○ 0 = disable
○ 100 = sample every 100ns
13. Types of Profiles: Mutex
● Added in Go1.8
● Block showed us blocked routines; Mutex profile shows us blockers
○ Specifically, which routines spend time holding a mutex
● Disabled by default; call runtime.SetMutexProfileFraction() to enable
15. Types of Profiles: Mutex (cont.)
● What if we use a RWMutex?
○ RLock/RUnlock are not tracked; RWMutex.Lock/Unlock are though
○ Milestone for Go1.9; https://github.com/golang/go/issues/18496
16. Types of Profiles: Custom!
● runtime/pprof exposes an API for creating our own profiles!
19. When to Use Custom Profiles
● Track a critical resource in your application
○ Open files
○ Active DB handles
○ Open Network sockets
○ In-use worker routines
● Make it easier to identify resource leaks in our apps
● We can also identify contention around bounded resources
20. A real-world case for custom Profiles
● I added support for tracking active-queries in a service at VividCortex!
○ Now it’s easier for us to track db-concurrency in our apps
21. What’s next for pprof?
- Support tracking file descriptors? https://github.com/golang/go/issues/16379
- Profile non-heap memory too? https://github.com/golang/go/issues/15848
- Count-oriented custom profiles? https://github.com/golang/go/issues/18454
- Allow aggregating events forever rather than showing current-state only
- Accepted proposal, Go1.9 milestone
- Support profiles with labels: https://github.com/golang/go/issues/17280
- Accepted proposal, Go1.9 milestone
