How to Find a Plastic Injection Molding Machine in Bellevue ?

Whether the fabricator’s shop is large or small, the Ironworker is the backbone. The Ironworker isn’t a single machine; it is five machines united into an engineering wonder. It has much more versatility than most people would imagine. The five working sections that are involved in the make-up of this machine are a punch, a section shear, a bar shear, a plate shear, and a coper-notcher.

A number of the cheaper ironworkers are constructed to employ a fulcrum where the ram shakes back and forth, building the punch go into the die at a small angle. This normally leads to the eroding of the punch and succumb on the front rims. The higher quality machines integrate a ram which moves in a direct vertical line and utilizes modifiable gibs and guides to ensure a constant traveling route.

Intel dominated and defined the semiconductor landscape during the PC era on two complementary fronts — silicon process technology and computing architecture (x86). Through its partnership with Microsoft, Intel enjoyed a near complete monopoly over the computing landscape during the PC era. That dominance began to erode with the emergence of two Segment Zero markets (Link) for Intel — embedded computing and mobile computing. The company that under the leadership of Andy Grove had successfully identified and vanquished at least two prior disruptive threats (Japanese memory makers in the 1980s and low cost PCs in the early 1990s) failed to successfully prepare for the next disruption — mobile computing and the ecosystem pioneered by ARM, the leader in low-cost/low-power architecture. While Intel pioneered the era of the standalone CPU with a vertically integrated business model, ARM enabled a massive lateral design/foundry ecosystem and pioneered the era of the mobile SoC (system-on-a-chip).

CPU vs. SoC

In the CPU space, chip functionality is largely determined by the computing core (e.g. Pentium, Athlon) and transistor performance is the critical metric. In the SoC space, the core is just one among a variety of IP blocks that are used to independently deliver functionality. Intel’s foray into SoC technology started in the early 2000s and was largely a response to the success of the foundry ecosystem. However, Intel’s SoC process technology has typically been implemented 1–2 years behind its mainstream CPU technology, which historically has focused on transistor scaling and performance. The foundries within the ecosystem instead focused on integrating disparate functional IP blocks on a chip while also aggressively scaling interconnect density.

The semiconductor industry today is increasingly driven by low-power consumer electronics (primarily smartphones) and SoC shipments now dominate total silicon volume. The sheer volume of desktop class computing chips like Apple A9 SoCs shipped to date has in turn dramatically improved the competitiveness of the foundry ecosystem (led by TSMC) compared to Intel. Until a few years ago, Intel’s process technology lead was unquestioned. That lead is now greatly diminished as the foundry ecosystem is on track to ship more 64 bit SoC chips than Intel by the end of this year.

The ascendance of ARM has not only displaced Intel’s leadership on the architecture front (x86) but indirectly, also on the process technology front by enabling the foundry ecosystem to ship incredibly large volumes of leading edge silicon and dramatically speeding up the manufacturing yield learning curve. Intel was late in recognizing the importance of the SoC and now finds itself playing catch-up to a strong ecosystem led by ARM on the architecture front and TSMC on the silicon process technology front.

Compounding this trend further is the reality that after 50 years of delivering consistent gains in power, performance and cost; transistor scaling is finally entering an era of diminishing returns where further shrinking the device is not only costly, but provides incremental gains in performance and power.

Meanwhile, the ARM ecosystem is also steadily making inroads into the high-end space traditionally dominated by Intel. Several new tablet and laptop computers (e.g. Google Pixel C) use SoC chips designed by fabless companies instead of CPU solutions from Intel. Over time, SoCs became much more powerful and competitive and now pose a meaningful threat to the standalone CPU. The predominance of the Intel-Microsoft partnership based on x86 architecture is waning and a huge swath of the mobile computing space is now supported by low cost Chinese design houses like MediaTek, AllWinner, RockChip and Spreadtrum that use ARM architecture and foundries like TSMC, SMIC or UMC.

The emergence of the SoC was thus a strategic inflection point for both Intel and the ARM ecosystem alike. While the silicon landscape during the PC era was defined by Intel and the CPU, it is fair to say that the silicon landscape during the mobile era continues to be defined by the SoC and the foundry ecosystem led by ARM and TSMC. In many ways, Intel’s ability to compete in the SoC space will determine the direction of the chip wars in the next wave of computing (IoT).

Transistor Technology

The process technology underlying CPUs and SoCs is similar, however the design points for each can be vastly different. For example, a CPU design requires fewer transistor variants spanning a limited range of leakage and speed. On the other hand, SoC designs require many more transistor variants spanning a much wider range of leakage and speed. SoC technology also needs to support higher supply voltages for IO devices (e.g. 1.8V, 3.3V) in addition to the nominal supply voltage for core devices (e.g. 0.9V) These differences, though subtle, require very different mindsets in transistor design and process architecture.

Intel’s focus on transistor performance can be traced back to the height of the PC wars when the benchmark was clock speed. While Intel focused on transistor performance, the foundries adapted Intel’s transistor innovations for their own SoC integration needs. In addition, they aggressively pursued metal density scaling and cost reduction. While Intel pursued a limited vertical functional integration, the foundries developed a lateral ecosystem and designed transistors for a variety of vendors that independently optimized functionality for each IP block (CPU, GPU, radio, modem, GPS, IO, SERDES, etc.).

This vast ecosystem of existing design IP is now a significant influence on the adoption of the next transistor architecture. Arguably, the foundries are today better positioned for the SoC era. By the end of 2015, TSMC will have shipped well over 100 million units of Apple’s A9 SoC. These processors are made in 16nm technology and will set new benchmarks for cost, power and connectivity features. The Apple A9 processor is possibly the most highly integrated SoC running on the most advanced silicon process technology (at TSMC and also Samsung). Intel’s advantage at the transistor level thus allowed it to win the CPU space, but the ecosystem has the advantage at the system level and is poised to win the SoC space.

In the mobile and IoT era, packing as many features on a chip as possible at the lowest integrated system cost and power will win. The transistor technology that is most compatible with all the IP needs of a complex SoC at the lowest cost will thus have the upper hand.

The Post-PC Era: Intel in an Open Ecosystem

The slowdown in the pace of Moore’s Law, the emerging importance of the SoC and the rapid growth of the mobile market all tend to favor an open, plug-and-play foundry and design ecosystem. One could expect that the ecosystem developing around ARM will continue to nip at Intel’s core markets as the development of ARM-based processors for laptops and servers accelerates. This emerging threat to Intel and Intel’s response to it will define the industry over the coming decade.

The operating system (OS) war between Microsoft and Apple in the 1980s came to define the PC and software industries. Microsoft’s open ecosystem model won as Windows became the de-facto OS for machines made by all kinds of PC makers. While Microsoft promoted an open ecosystem in the larger PC industry, ironically it spawned a closed ecosystem within the semiconductor industry. The Wintel alliance ensured that Windows only ran on x86 architecture which was pioneered and owned by Intel. The closed ecosystem hugely benefited Intel as it went on almost unchallenged to win the desktop, laptop and server space (AMD also used x86 yet could never match Intel’s scale or manufacturing expertise). A hallmark of the post-PC era is the emergence of an open ecosystem within the semiconductor industry.

Unlike the Windows/x86 dominance of the past, the post-PC era is being defined by competing OS options (iOS, Android or Windows) and competing processor architectures (x86 or ARM). Today, the momentum is in favor of ARM-based operating systems as the vast majority of mobile devices being shipped today run iOS or Android (ARM architecture).

The chip wars will be fought in this fragmented and open ecosystem on three fronts — SoC (system integration), CPU (core architecture) and silicon (foundry technology). While performance and power will continue to be important benchmarks, the open ecosystem supporting a worldwide consumer market will make cost a key success metric on each battlefront.

Battlefront #1 — SoC (System Integration)

In the mobile SoC space, the battle for processor architecture will be between Intel on the one hand and incumbents like Qualcomm, Samsung and Apple on the other. In the mobile, power constrained space, it is more efficient to integrate a variety of hardware accelerators on a single chip to deliver custom functionality as opposed to implementing a general purpose core serving most functions. Low power cores are supplemented with elements as disparate as an on-chip radio, global positioning system (GPS), modem, image and audio/video processor, universal serial bus (USB) connectivity and a graphics processing unit (GPU). An open ecosystem is far more cost-effective for such modular, plug-and-play system-level integration.

A typical CPU design (Intel Core-M) dominated by core/graphics compared to a highly integrated SoC (NVIDIA Tegra 2). The integrated SoC design has obvious advantages in mobile formfactors.

Historically, Intel, being an integrated device manufacturer (IDM) has independently designed most of the functional IP blocks, while ensuring that each uses Intel transistor technology and process design rules. Intel’s process technology leadership has benefited it enormously in the CPU space giving its designers access to best-in-class transistor performance. However, Intel’s ability to compete in the mobile SoC space will be determined by how well it can re-engineer its CPU process technology to meet the diverse needs of a complex mobile SoC.

If Intel can successfully design and manufacture 14nm and 10nm processes that span the full range of the performance-power spectrum required for mobile SoC applications, it will have an edge over the competition. But for Intel to compete effectively in the mobile SoC space, it will also need to offer a cost advantage. Average Selling Price (ASP) in the SoC space is a fraction of that in the CPU space. While fabless Apple can drive the best possible deal from competing foundries, IDM Intel needs to ensure that its volumes and ASPs are high enough to recoup its own development and manufacturing CapEx.

Intel may try to enhance its SoC functionality offering by way of more acquisitions like Infineon Wireless. But post-merger, porting Infineon’s foundry standard design rules to Intel’s proprietary design rules will be non-trivial (In 2015, nearly 5 years after the acquisition, Intel is yet to port Infineon’s modem chips to their own fabs and continues to make them at TSMC!). By contrast, the Qualcomm acquisition of Atheros likely proved to be more seamless since the IP was from the open ecosystem and already foundry compatible.

Battlefront #2 — CPU (Core Architecture)

The main battle on the CPU front is between Intel/x86 and ARM architecture. While Intel historically has had the upper hand in performance, ARM-designed cores have delivered superior performance/watt.

To effectively compete against ARM, Intel will need to design its low-power Atom cores in the most power-efficient way possible. To design a true low-power core, Intel may need to decouple the Atom from legacy x86-based architecture and develop a new ground-up design that delivers highly competitive performance/watt.

Intel will also have to be in aggressive catch-up mode as it tries to reverse the momentum of an already large, established and robust ARM software ecosystem. In the initial years of the PC era, as x86 became the predominant CPU architecture, an entire ecosystem of application software was spawned that was designed to run solely on x86. This effectively precluded or seriously hindered competing architectures like PowerPC from ever gaining a foothold in the marketplace. Analogously, in the present day, ARM architecture is significantly further along in achieving critical mass in the mobile SoC space. The prevalence of ARM in a range of post-PC devices from smartphones and tablets (90% market share) to televisions and cars has placed ARM in a commanding position to inhibit the newer Intel Atom architecture from achieving traction. Practically speaking, for Intel to gain a meaningful share in the mobile market, it now has to ensure compatibility with the ARM software ecosystem. This again, will force Intel to compete on price which will limit how much revenue it can eventually generate. This is a dynamic that Intel never had to face in the PC segment.

Battlefront #3 — Silicon (Foundry Technology)

Intel’s ability to make the best performing transistor at the highest possible yields and volumes is unparalleled. This capability served it immensely well in the closed ecosystem when Intel was essentially competing against itself in the quest to make a smaller and faster transistor. In the closed ecosystem, performance trumped power; and design flexibility and high ASPs ensured that development cost was not a significant limiter.

In the open ecosystem, however, the ability to integrate disparate functional accelerators in the most power-efficient and cost-effective manner is paramount. As an example, TSMC is able to deliver the highly successful and functional A9 processor for Apple using a state-of-the-art 16nm transistor process and integrate a variety of complex IP blocks while keeping the ASP under $20. TSMC’s minimum metal pitch at the 16nm node is larger (i.e. less dense) than that of Intel at the more advanced 14nm node, yet the A9 SoC can offer better power efficiency than a comparable 14nm CPU at an acceptable performance point and much lower price point and a much smaller form-factor.

In the post-PC era, mobile and IoT computing will have a larger influence on the semiconductor landscape. The success metrics in the new landscape are not just higher transistor performance but higher system functionality, lower system cost and lower power.

Based on the above discussion and judgment, the following trends are likely to define the semiconductor industry over the next decade.

  1. Shrinking pool of advanced semiconductor fabs: The economics of Moore’s Law and the advent of mobile computing have led to a dramatic reduction in the number of advanced semiconductor manufacturing sources. Just 3 major entitities (Intel, Samsung, TSMC) now offer unique 16nm or advanced technology. (Globalfoundries is effectively just a manufacturing partner for Samsung). A wildcard here is SMIC (Semiconductor Manufacturing International Corporation, Shanghai). Even though it is a relative newcomer, SMIC is extremely driven and has the full backing of the Chinese government which has made advanced semiconductor manufacturing a national priority. SMICs entry at 14nm (by 2020) may change the foundry landscape by dramatically altering silicon wafer price-points.
  2. Making things smaller doesn't help much anymore: The 28nm node will be the longest running planar transistor technology. In a departure from prior technologies, and in response to plateauing transistor cost, the leading foundry (TSMC) has developed over 5 flavors of the technology for all applications ranging from high performance 28HPM (FPGA, GPU, mobile SoC) to ultra-low power 28ULP (IoT edge computing). As the mobile computing era matures and the IoT computing era emerges, majority of the applications will be served by 28nm or older technology. As technology development lifecycles get longer and product lifecycles get shorter, foundries will try to extract all the goodness in an existing transistor technology before moving to the next one.
  3. Even fewer applications for advanced technologies: Only a minority of applications (e.g. high performance computing, AI/AR, machine learning, computer vision) will migrate to using sub-10nm and lower technology nodes. And these advanced nodes will also be long lived with multiple variants serving disparate power/performance/cost points.
  4. Intel CPU leadership: Intel will continue to dominate the single thread/high performance CPU/server segment, albeit with increasing competition from the ARM ecosystem. Intel’s acquisition of Altera is a defensive move aimed at creating a moat around its server leadership. However, the next five years will likely see the emergence of competitive ARM based servers. Using an open ecosystem with customizable IP will enable significant cost and power reduction for these new entrants.
  5. Lego block on-chip integration: In the power and cost competitive IoT era, on-chip integration of hardware accelerators (modem, CPU, graphics, etc) will continue to be extremely efficient. Compared to centralized CPU/GPU cores, SoCs will be far more effective, especially in the smartphone, tablet and convertible form-factors. As silicon scaling plateaus, packing as many disparate functional blocks as possible on a chip within a given transistor budget at the lowest integrated system cost and power will win. Companies will try to expand their footprint by capturing more real estate on the chip, either through consolidation or on their own.
  6. Ascendance of the SoC: Intel’s 14nm CPU (Skylake, 2015) and Apple/TSMC’s 16nm SoC (Apple A9, 2015) are two marquee technologies/products that will provide a barometer on the semiconductor landscape. Several benchmarking results indicate that the A9 is perhaps the most efficient mobile SoC with unparalleled performance/power metrics. This match-up will have remarkable implications — not only will it validate the rise of Apple as the dominant SoC design team, it will also suggest a vulnerability in Intel’s process technology leadership. It suggests that TSMC could go toe-to-toe with Intel on radical and highly complex transistor architectures (16/14nm tri-gate), while also supporting best-in-class SoC technology which is the enabling platform for mobile and IoT computing. Intel will need to dramatically improve its SoC offering in the years to come in order to be competitive in the SoC/IoT space.
  7. Slowing cadence of Moore’s Law: Two technologies that have the potential to significantly influence the economics of Moore’s Law and disrupt the industry cost model are (a) 450mm wafer size and (b) EUV lithography. However, a glut of fully depreciated 300mm fab infrastructure and decades long slow progress in the EUV tooling roadmap will make it a difficult value proposition at least in the foreseeable future. Conventional Moore’s Law scaling is likely to give way to more orthogonal scaling approaches (More-than-Moore) including 3D chip stacking and system/package level integration of heterogeneous chips.

Obviously enough, one of the first things many people want to know when getting started with scrolling as a hobby is what saw to buy. Whether you are looking to purchase your first scroll saw, or you are looking to upgrade to a better one, there are many things to consider. In this article I will attempt to touch on all aspects so that you are able to make an informed decision. I will also make some recommendations based on personal experience and what I feel is the general consensus of the scroll sawyers I have discussed the matter with.

Important Considerations

Blade Changing and Blade Holders: The saw should accept standard 5" pinless blades. A lot of scrollwork simply cannot be done with a saw that requires pinned blades. While pinned blades have some advantages, they have one very big disadvantage: You can't cut any small inside detail cuts since you have to drill a very big hole to get the blade's pin through.

Also, how easy is it to change a blade? Is a tool required for this? Some scroll saw projects have hundreds of holes. This means you have to remove one end of the blade from the holder and thread it through the wood and re-mount it in the holder more times than you can count. Be sure the process is comfortable and relatively easy to do. A saw in which the arm can be raised and which holds itself in this position is most desirable as it makes this process much easier as do tool-less blade holders.

Variable speed: A great many saws offer variable speed and you should not have a problem finding this feature in any price range. Sometimes you will want to slow the blade down just to cut slower, other times you must slow it down to prevent the blade from burning the edges of the wood as you cut. Some scroll saws require belt changing to change speeds. Personally, I would highly recommend a saw an electronic speed control.

Vibration: Vibration is very distracting when cutting and must be kept to a bare minimum. Some saws inherently vibrate more by design. This feature tends to be very much dependent on the cost of the particular saw. Vibration can be reduced by mounting the saw to a stand. A sturdily mounted saw and heavier saw/stand combination will reduce vibration. Many companies offer stands purpose built for their saws.

Size Specifications: Manufacturers often list the maximum cutting thickness of their saws. Since this is always more than 2", you can ignore this as you likely will never want to cut anything thicker than that on a scroll saw.

The depth of the throat however is something you may want to consider if you think you will be cutting very large projects. A small throat will limit how big of a piece you can swing around on the table while you cut. For many this is not a very big deal since it is somewhat difficult and unpleasant to swing around a big piece of wood on a scroll saw. This limit can also be circumvented by the use of spiral blades which don't require the work to be rotated at all.

A most notable difference between the Excalibur and other saws is that the head of the saw tilts rather than the table. This is a nice advantage if you intend to do a lot of angled cutting. The one feature that I personally am leery about is that you only have a quick release for the tension at the front of the saw's upper arm and the fine adjustment is at the back of the arm. This is a relatively recent change to the saw however I have not seen any negative feedback about this setup. Theoretically, once you have set the fine adjustment, you don't have to adjust it very often and you just need the quick release when undoing/redoing the blade to feed it through your project.

These saws are manufactured by General International, which has a reputation for quality.

Other notable mentions RBI and Eclipse both offer high end saws with great performance and low vibration. You may want to check these saws out if you can afford them. Since they are out of most people's price range, I have not heard a whole lot of feedback on them. In my opinion, many of these models do however have inconveniently located controls and/or require tools for blade changes which do give me cause for concern.

Hegner offers four different models starting at about $700 and going all the way to $2400. The lowest end model "Multimax 14-E" is only single speed which I would definitely stay away from. In my opinion there are several better choices for a comparable or cheaper price. The $2400 industrial "Polymax" model requires belt changing to change the speed which is an inconvenience. Because of this issue and the high price tag, I would only consider this model for a truly industrial purpose. This leaves us with the Mutimax 18-V and 22-V models to consider.

All Hegner saws require tools for blade changes. This fact, in addition to what I would personally consider an inconvenient control layout would make me think twice about a Hegner. That being said, most people who own Hegners are very happy with the quality and usability of their saws. Since I have not personally used one, I will leave this matter for your further consideration if you can afford a saw in this price range.

Conclusion

I hope this article has provided you with enough information to allow you to make the best possible investment of your money so that you can start with or upgrade to a scroll saw that will provide you years of scrolling pleasure.

Crypto Briefing

Story after story of top talent in Financial firms and Wall Street pivoting to start their own crypto and blockchain startups. The most recent is J.P. Morgan’s former head of blockchain, Amber Baldet, who has announced a new blockchain start-up called Clovyr.

Or there is this guy, who claims Bitcoin could reach as high as $50,000 by the end of 2018.

Regarding the advent of blockchain there’s a nice video here by Fortune. Amber, who most recently served as the bank’s blockchain program lead at JP Morgna Chase, is co-founding a new startup, Clovyr, that aims to help consumers, developers, and businesses explore the nascent, albeit burgeoning, world of blockchain-based, decentralized technologies.

Baldet hopes she can:

Help people think differently about decentralized application design.
  • Baldet’s post-J.P. Morgan plans have been the topic of speculation since she announced her departure from the bank in April. This is part of a growing trend, the writing is on the wall for Wall Street firms that do not remain agile, and now is the right time to pivot to the blockchain and crypto that are still somewhat nascent and could eventually disrupt financial markets and how financial services work on very fundamental levels.
Shaun Mader | FilmMagic | Getty Images

Amber won’t be the first or the last to leave the comfort of Wall Street, let’s remember where Jeff Bezos got his mathematical and strategic roots.

Baldet unveiled a Clovyr demo at the Consensus conference in Manhattan on Monday afternoon, May 14th, 2018. They are fundraising now as well.

Will Clovyr be the Apple Store for Decentralized Apps?

Baldet co-founded Clovyr with Patrick Nielsen, who led development for J.P. Morgan’s open source blockchain projects.The new company will offer something similar to an app store, but for “decentralized applications” which exist on a blockchain, points out CNBC.

Build it and they will come, we know that the blockchain is coming, even Amazon announced another major partner in its efforts on the cloud. We already knew this but Amazon’s cloud computing arm is now teaming up with startup Kaleido to help simplify blockchain technology for its clients.

Clovyr feels very much like a B2B platform dApp ecosystem in the making:

Clovyr is a decentralized application store that will host a selection of well-vetted applications alongside some in-house developer tooling designed to simplify application development for enterprises.

Seriously though, who would not want to invest in something like this?

Fortune Video

Anticipating the future is not very hard if you are a blockchain enthusiast. She is joined by Nielsen (above), former lead developer of Quorum, a JPMorgan Chase-built blockchain for business, who will serve as the concern’s chief technologist. If JP Morgan Chase is not even able to retain it’s top blockchain people, something is seriously wrong with their R&D model.

Or hang on a second, is this a spin-off play by JP Morgan itself? The report goes on to say: maintaining a “blockchain agnostic” approach to application design, Clovyr will initially provide tooling to build on both public and enterprise versions of ethereum, specifically the Quorum. These Wall Street firms know that they have to appear independent with their innovation startups to gain trust of Millennials. Someone that calls Bitcoin idiotic is probably not on the inside track of trust to the crypto hoard.

What Clovyr reminds me of is essentially a “Shopify of Crypto”, as the cofounders envision the platform serving as a neutral ground, offering a browser-like dashboard for the blockchain-curious, through which Clovyr can provide support and other services to customers according to their needs.

Does the concept make any sense to you?

Today, we’re announcing Dart 2, a reboot of the language to embrace our vision of Dart: as a language uniquely optimized for client-side development for web and mobile.

With Dart 2, we’ve dramatically strengthened and streamlined the type system, cleaned up the syntax, and rebuilt much of the developer tool chain from the ground up to make mobile and web development more enjoyable and productive. Dart 2 also incorporates lessons learned from early adopters of the language including Flutter, AdWords, and AdSense, as well as thousands of improvements big and small in response to customer feedback.

Dart’s Core Tenets

Before we talk more about the advances in Dart 2, it’s worth identifying why we believe Dart is well positioned for the needs of client-side developers.

In addition to the attributes necessary for a modern, general purpose language, client-side development benefits from a language that is:

  • Productive. Syntax must be clear and concise, tooling simple, and dev cycles near-instant and on-device.
  • Fast. Runtime performance and startup must be great and predictable even on small mobile devices.
  • Portable. Client developers have to think about three platforms today: iOS, Android, and Web. The language needs to work well on all of them.
  • Approachable. The language can’t stray too far from the familiar if it wishes to be relevant for millions of developers.
  • Reactive. A reactive style of programming should be supported by the language.

Dart has been used to ship many high-quality, mission-critical applications on the web, iOS, and Android at Google and elsewhere and is a great fit for mobile and web development:

  • Dart increases developer velocity because it has a clear, succinct syntax and is able to run on a VM with a JIT compiler. The latter allows for stateful hot reload during mobile development, resulting in super fast dev cycles, where you can edit code, compile and replace in the running app on the device.
  • With its ability to efficiently compile to native code ahead of time, Dart provides predictable, high performance and fast startup on mobile devices.
  • Dart supports compilation to native code (ARM, x86, etc.) for fast mobile performance as well as transpilation to efficient JavaScript for the web.
  • Dart is approachable to many existing developers, thanks to its unsurprising object-oriented aspects and syntax that — according to our users— allows any C++, C#, Objective-C, or Java developer to be productive in a matter of days.
  • Dart works well for reactive programming with its battle-hardened core libraries, including streams and futures; it also has great support for managing short-lived objects through its fast generational garbage collector.

Dart 2: Better Client-Side Development

In Dart 2, we’ve taken further steps to solidify Dart as a great language for client-side development. In particular, we’ve added several new features including strong typing and improving how UI is defined as code.

Strong, Sound Typing

The teams behind AdWords and AdSense have built some of Google’s largest and most advanced web apps with Dart to manage the ads that are bringing in a large share of Google’s revenue. From working closely with these teams, we identified a big opportunity to strengthen Dart’s type system. This helps Dart developers catch bugs earlier in the development process, better scale to apps built by large teams, and increase overall code quality.

This isn’t unique, of course. In the broader web ecosystem, there’s also a growing trend towards adding type annotations to JavaScript. For example, TypeScript and Flow both extend JavaScript with type annotations and inference to improve the ability to analyze code.

In the small example below, Dart 2’s type inference helps uncover a somewhat subtle error and as result, helps improve overall code quality.

What does this code do? You could reasonably expect that it would print ‘27’. But without Dart 2’s sound type system enabled it prints ‘10000’, because that happens to be the least element in the list of strings when ordered lexicographically. With Dart 2, however, this code will give a type error.

UI as Code

When creating UI, having to switch between a separate UI markup language and the programming language that you’re writing your app in often leads to frustration. We’re striving to make the definition of UI as code a delightful experience to dramatically reduce the need for this context switching. Dart 2 introduces optional new and const. This much-requested feature is very valuable on its own, and also sets the direction for other things to come. For example, with optional new and const we can clean up the definition of a UI widget so that it doesn’t use a single keyword.

Client-Side Uses of Dart

Mobile

One of the most significant uses of Dart is for Flutter, Google’s new mobile UI framework to craft high-quality native interfaces for iOS and Android. The official app for the hugely popular show Hamilton: The Musical is an example of what Flutter is enabling developers to build in record time. Flutter uses a reactive programming style and controls the entire UI pixel by pixel. For Flutter, Dart fits the bill in terms of ease of learning, reactive programming, great developer velocity, and a high-performance runtime system with a fast garbage collector.

Web

Dart is a proven platform for mission-critical web applications. It has web-specific libraries like dart:html along with a full Dart-based web framework. Teams using Dart for web development have been thrilled with the improvements in developer velocity. As Manish Gupta, VP of Engineering for Google AdWords, explains:

The AdWords front-end is large and complex, and is critical to the majority of Google’s revenue.We picked Dart because of the great combination of perf and predictability, ease of learning, a sound type system, and web and mobile support.Our engineers are two to three times more productive than before, and we’re delighted we switched.

Moving Forward

With Flutter and Dart, developers finally have the opportunity to write production-quality apps for Android, iOS, and the web with no compromises, using a shared codebase. As a result, team members can fluidly move between platforms and help each other with, e.g., code reviews. So far, we have seen teams like AdWords Express and AppTree share between 50% and 70% of their code across mobile and web.

Dart is an open source project and an open ECMA standard. We welcome contributions to both the Dart core project and the ever growing ecosystem of packages for Dart.

You can try out Dart 2 in Flutter and the Dart SDK from the command line. For the Dart SDK, get the latest Dart 2 pre-release from the dev channel and make sure to run your code with the --preview-dart-2 flag. We also invite you to join our community on gitter.

With the improvements announced today, Dart 2 is a productive, clean, battle-tested language that addresses the challenges of modern app development. It’s already loved by some of the most demanding developers on the planet, and we hope you’ll love it too.
