Talbott Crowell introduces F# 3.0 including function programming basics, units of measure, and the new F# 3.0 feature called Type Providers for analyzing Big Data
History of F#, and the ML family of languages. Rachel Reese
After I switched from C# (a curly-brace heavy object-oriented language) to F# (a whitespace-sensitive functional language) a few years ago, I started to wonder about the history of programming languages and how they evolve. How does a feature in one language influence a feature in another language -- for instance, where did type providers come from? In this talk, I cover the history of MLs from approximately the dawn of time, eventually focusing on F# specifically.

Are you responsible for developing satellite on-board software? Are you the Dutch government and you have to efficiently implement the public benefits law? Are you a healthcare startup, developing companion apps that help patients through a treatment? Are you an insurance company struggling to create new, and evolve existing products quickly to keep up with the market? These are all examples of organisations who have built their own domain-specific programming language to streamline the development of applications that have a non-trivial algorithmic core. All have built their languages with Jetbrains MPS, an open source language development tool optimized for ecosystems of collaborating languages with mixed graphical, textual, tabular and mathematical notations. This talk has four parts. I start by motivating the need for DSLs based on real-world examples, including the ones above. I will then present a few high-level design practices that guide our language development work. Third, I will develop a simple language extension to give you a feel for how MPS works. And finally, I will point you to things you can read to get you started with your own language development practice.

Visual programming (pemrograman visual) adalah pendekatan dalam pemrograman komputer yang memungkinkan pengguna untuk membuat program melalui antarmuka grafis yang intuitif dan mudah digunakan. Dalam pemrograman visual, pengguna menggambar diagram atau ikon yang merepresentasikan operasi atau fungsi yang ingin dilakukan oleh program, lalu menghubungkannya dengan garis atau panah untuk membentuk alur logika.
Pemrograman visual memiliki beberapa keuntungan dibandingkan dengan pemrograman teks tradisional. Pertama, pemrograman visual lebih mudah dipelajari oleh pemula karena antarmuka grafis yang intuitif. Kedua, pemrograman visual dapat membantu pengguna memvisualisasikan alur program secara keseluruhan, sehingga memudahkan pengguna untuk memahami bagaimana program bekerja. Ketiga, pemrograman visual dapat mempercepat proses pengembangan program karena menghilangkan kebutuhan untuk mengetik kode secara manual.
Contoh dari bahasa pemrograman visual termasuk Scratch, Blockly, dan LabVIEW.
Domain Specific Languages: The Functional WayTomas Petricek
In software development, we often face the same problem over and over again. For example, when designing user-interfaces, we need to specify the layout of components; when designing financial systems, we need to detect various patterns in changing prices. The Domain Specific Language (DSL) approach is to design a language for the specific problem domain and then use it repeatedly to solve multiple instances of the same problem.
In this talk, we look how to think about DSLs in a functional way. This lets us focus on the domain. Rather than worrying about the syntax, we start by understanding what problems we actually want to model and what is the best way to do so. Along the way, we’ll look at three fun examples ranging from a language for building 3D objects to a language for detecting price change patterns.
With mobile taking off in a big way it is a fun and exciting time to be a software developer. The landscape is rapidly changing, with a wide variety of options for platforms and programming languages. Businesses are faced with tough decisions on how to provide a best possible user experience, yet keeping maintenance cost down across the different smart phone platforms.
Some are compromising user experience and betting on web based interfaces, while others require the high fidelity user experience or device integration traditionally only found in native apps.
In this session I will demonstrate how we can write fully native applications taking full advantage of the platform, yet achieving a high level of code reuse across Windows Phone 7, Android and iOS.
Topics covered:
- Separated Presentation patterns for maximum code reuse across all platforms
- How to structure your source code and build it for all platforms
- How to access devices specific functionality like Camera, GPS and Accelerometer in a cross platform way
- Tips, tricks and tools to make the cross platform development process smoother.
For maximum benefit from this session some prior knowledge of MVVM is beneficial.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Editor's Notes
1973, Robin Milner at the University of Edinburgh developed the ML programming language to develop proof tactics for the LCF Theorem prover. Lisp continued to be used for years as the favored language of AI researchers.ML stands out among other functional programming languages; its polymorphic functions made it a very expressive language, while its strong typing and immutable data structures made it possible to compile ML into very efficient machine code.L's relative success spawned an entire family of ML-derived languages, including Standard ML, Caml, and its most famous dialect called OCaml which unifies functional programming with object-oriented and imperative styles.F# is essentially a .Net implementation of OCaml, combining the power and expressive syntax of functional programming with the tens of thousands of classes which make up the .NET class library.
Mars Climate Orbiter ble skutt opp 11. desember 1998. Oppdraget var å studere været, klimaet, og vann- og karbondioksidinnhold på planeten Mars. Den 23. september 1999 skulle farkosten gå inn i bane rundt Mars, men en beregningsfeil resulterte i at Mars Climate Orbiter gikk inn 90 km for lavt. Dette førte til for store påkjenninger og friksjon fra Mars atmosfære, og fartøyet gikk i oppløsning.
NASAs undersøkelser etter ulykken avdekket at feilen skyltes en software-feil, hvor to delsystemer brukte forskjellig sett med måleenheter. Det ene systemet brukte imperiske enheter (pound-seconds, lbf*s) istedenfor metriske enheter (newton-seconds, N·s) som spesifisert av NASA.
Mars 2012: Microsoft's F# continues to evolve, with the recent release of F# 3.0 beta. F# is excellent at concisely expressing business and domain logic. Developers trying to achieve explicit business logic within an application may opt to express their domain in F# with the majority of plumbing code in C#.
