For developers, having the data where it is needed is a non-trivial challenge. Mobile, IoT, and edge computing challenge cloud-centric solutions where data and processing is done centrally. Decentralized computing along with data locality bring back autonomous apps, which don't depend but coexist symbiotically with the cloud. This does not only reduce cloud costs, but also increases security by reducing the amount of data shared with central instances. Can blockchain be part of the solution?
IoT, computer intelligence and javascript in the physical worldIvo Andreev
IoT and Computer Intelligence are two of top technology trends nowadays. But do these sound too far for a JavaScript or web developer?
Microsoft Cognitive Services have brought computer intelligence at your fingertips by letting you use powerful algorithms with just few lines of code. So as Technical Machine who made Tessel – an open-source Internet connected microcontroller that is programmable in JavaScript.
Since Microsoft reputation of usability speaks on its own and Tessel is Node.js compatible, there is a large eco system to dive in and start making smart applications as if you are developing for the web.

https://www.kalix.io/blog/kalix-move-to-the-cloud-extend-to-the-edge-go-beyond
Abstract:
What will the future of the Cloud and Edge look like for us as developers? We have great infrastructure nowadays, but that only solves half of the problem. The Serverless developer experience shows the way, but it’s clear that FaaS is not the final answer. What we need is a programming model and developer UX that takes full advantage of new Cloud and Edge infrastructure, allowing us to build general-purpose applications, without needless complexity.
What if you only had to think about your business logic, public API, and how your domain data is structured, not worry about how to store and manage it? What if you could not only be serverless but become “databaseless” and forget about databases, storage APIs, and message brokers?
Instead, what if your data just existed wherever it needed to be, co-located with the service and its user, at the edge, in the cloud, or in your own private network—always there and available, always correct and consistent? Where the data is injected into your services on an as-needed basis, automatically, timely, efficiently, and intelligently.
Services, powered with this “data plane” of application state—attached to and available throughout the network—can run anywhere in the world: from the public Cloud to 10,000s of PoPs out at the Edge of the network, in close physical approximation to its users, where the co-location of state, processing, and end-user, ensures ultra-low latency and high throughput.
Sounds exciting? Let me show you how we are making this vision a reality building a distributed real-time Data Plane PaaS using technologies like Akka, Kubernetes, gRPC, Linkerd, and more.

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
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.

3. Hello daho.am :)
• Local event
Decentralized
Efficient information exchange
Connects local people
• Local data at the edge
Decentralized
Efficient information exchange
Connects local devices
4. Mobile Data – My personal Journey
• Previous life: enterprise stuff
Java, expensive DBs, SQL, O/R Mappers (ORMs)
• Apps, build two mobile ORMs on top of SQLite
Object lover, never a fan of SQL, respect for SQLite
• "We can do better than that"
ObjectBox – founder and CTO
5. What is the "Edge" and Edge Computing?
• Nothing really new
• Edge: devices on the edge of the Internet
E.g. mobile phones, desktops, IoT devices
• Edge gateways
Servers living on the edge
• Locality is a good thing
Goal: provide better solutions directly at the edge
6. And what's "Fog Computing"?
• Sometimes used in the same context (EC)
• "A hierarchic cloud"
Bring computing and data closer to the edge
• Locality levels
E.g. building, city block, city, …
7. So, what's wrong with the Cloud?
Nothing really.
It's just a little overused.
11. What happened to "It depends"?
• Cloud == 42?
• The universal answer of IT people: "It depends"
Complex stuff, 1000 different solutions
• Optimal solutions depend on the use case
• When is the Cloud the best solution?
It depends!
12. Cloud Advantages
• Vs. servers: scale & redundancy
Less to worry about, "managed" & less down time
• Central processing is simple
(Mostly) consistent state, easy to monitor, etc.
• Implementing logic just once
Clients just call an interface (e.g. Web/REST)
13. Cloud Disadvantages
• Central everything
Controlled by big companies (governments?)
Hack-able: one breach – millions affected
Who owns my data? Does private data exist?
• Depends on network
Clients are dead when offline, latency
• Cloud costs
14. Cloud adds Latency
• (Near) Real time requirements
E.g. Industrial setting
Cloud not an option
15. Cloud Costs for Apps
• Medium app, 150k monthly users
• Significant work to reduce cloud time
3 caching layers on the cloud side
• US $400-500 per month
• Wouldn't be affordable without caches
Also on-device database with "conditional gets"
• Big apps often spend > $100K per year on cloud
16. Cloud costs: IoT
• Source: CTO of an IoT company
• Single application, huge amount of sensor data
• Local K/V cache to mitigate costs
• Multiple € 100K per month
• "Cloud costs are a problem"
Very hard to make a project profitable
17. Is the Cloud the new Mainframe?
• Once upon a time…
• You could submit "jobs" to mainframes
• "Jobs" moved to desktop computers
• It happened before and it will happen again
• Move "Jobs" to the edge
18. Utilizing the Edge
• While you wait for the cloud…
• What are client devices doing?
• Nothing!
Waiting == wasting resources
• Edge computing is resourceful
Using the powerful resources we already have
19. Data on the Edge – local Data is good Data
• Upload of all data is often wasteful
Example: IoT sensors
Preprocessing & only upload what's needed
• Data that doesn't leave the edge
Private data stays "in the house"
• Again: Edge computing is resourceful
Decrease traffic & increase privacy
22. Simple Example: In-App Search is already EC
• App with some kind of catalog
E.g. news, TV data, messages, …
• Sync all (relevant) data to device
Archive could stay in the cloud
• Search data at the edge
Functionality at the device, not in the cloud
24. IoT devices
• More devices than humans
Likely to double in the next few years
• Big range of technical capability
From wearables to seriously powered devices
• The typical "dumb" device
Sends sensor data to the cloud
25. From IoT to EoT
• Does an "Internet of Things" make sense?
Again: it depends
• Edge of Things
"Internet exposure considered harmful"
• Smart home, edge version
Local area network
Optional gateway to the cloud
Decide what to share
26. Bringing Data to the Edge: Challenges
• Distributed data
Local data, some of it must be synchronized
• Keeping data in sync is complex
Concurrent edits, conflicts, …
• More data stored on device
Higher capacity needed (e.g. flash memory)
Data storage needs to scale (performance)
27. Status quo for getting Data to the Edge
• REST based APIs (or GraphQL)
Typically return JSON data
• No standard to store returned data
E.g. custom logic to insert into a SQL database
• Requests often fetch all data
Often redundant and inefficient
28. Data Sync is a Key Technology
for Edge Computing
29. Data Synchronization
• Generic approach to keep data up-to-date
Pushing updates two way
• Offline support
When not connected: queue updates for later
• Delta synchronization
Sending only deltas is much more efficient
• Conflict resolution
30. git: Good Example of Distributed Data
• Decentralized
• History is not linear
Branches introduce another dimension
• Merge operations
Automatic, or manual conflict handling
• git concepts data synchronization?
Makes a pretty good starting point
31.
32.
33.
34. git & Crypto: more Inspiration
• Chain of cryptographic hashes
Content is hashed
Previous commit hash is part of the hash
• Tampering data would break the hash chain
Considered a different branch, easy to track down
• Optional: signing
E.g. prove that a commit comes from you
35. Data Synchronization Implementation
• Transaction based databases
A transaction is a list of actions
• A transaction is a state transition
Actions & data can be stored in a log
• Each state should be identifiable (ID)
Enable clients to pick up from previous state
(aka delta synchronization)
36. Data Synchronization Implementation
• State ID can be a hash
Yep, just like git…
• State transition A B with transaction log TXL
hash(B) = hash(hash(A) + hash(TXL))
• Chain of hashes
• Clients can pick up from their last hash ID
Delta sync unlocked
38. Full Decentralization – Though Challenges
• Anarchy and Chaos?
No central instance may/can control/interfere
• Data bubbles
Data gets separated and inconsistent
• Trust issues
Which peers to trust?
41. Blockchain Achievements
• Alternative investments & a new mining industry
Eventually also new currencies
• Smart contracts
"If this then that" - combining data and code
• Crypto is cool again
• Working well enough
Showed the world that there are alternatives
42. Blockchain Tech
• Block of transactions
Merkle tree to produce a hash
• Diverging data/history
One branch is selected using a scoring model
(e.g. longest chain)
• Proof-of-work
Calc nonce to find special hash(content + nonce)
43. Blockchain Tech – the Dark Side
• Decentralized consensus: ridiculously inefficient
Compared to central instance approval
• Proof of work: "useless" expensive computation
Redundantly done by thousands of miner nodes
• Nonce lottery is like "wasting" ~99.99% of energy
• Effects on the environment?
• (Today's) blockchain is not the end of the journey
44. Data Sync vs. Blockchain
• Implementations can share concepts
Transactions, chained hashes
• Key difference: consensus and trust
Centralized vs. decentralized
• Centralized consensus is preferred for apps
Producing companies "own" their apps
(Efficiency restored… )
46. ObjectBox – a Database for the Edge
• "A DropBox for data objects"
Allows to work offline
• We start at the edge: embedded database
Based on objects and relations
Sync: stored bytes can be sent and applied 1:1
• Simplicity and efficiency
Guiding principles
47. ObjectBox
• Runs on mobile, desktop, IoT devices
Android, Linux, Windows, i/MacOS, Raspberry, …
• Low footprint: less than 1 MB
• 10x faster CRUD operations
Outperforms SQLite, fastest embedded DB
• ACID compliant
48. ObjectBox
• Objects all the way through
No transformations required
(no SQL, no REST/JSON parsing)
• Convenience at K/V store speed
Indexing, queries, relations
• ObjectBox 2.0 Release
25th July 2018
50. Edge Computing - the Golden Hybrid?
Centralized Decentralized
Server
Cloud
Peer-to-Peer
Edge
"Super Peers"
51. Data Dimensions
• Data localilty
Cloud, edge-only, shared cloud-edge
• Online vs. offline data
Online-only cloud, offline: synced or edge-only
• Consensus: which data prevails?
Central authority, decentralized heuristics
52. Questions to ask
• Who owns "my data"?
Can data be private at all?
• How much (de)centralization do you need?
What works best for your use case?
• How can we make efficiency a virtue again?
Can efficiency reduces your costs too?
