ZoomCharts at DevClub.lv: Developing a Javascript SDK
On January 15, 2015, ZoomCharts Co-Founder and CTO Viesturs Zariņš presented at DevClub.lv - a community of Latvian IT specialists that gather monthly and host free talks, presentations, and events to allow the local IT community to share knowledge, network, and communicate. Zariņš discussed the unique challenges faced in developing JavaScript SDK.
Here is a brief overview of his PowerPoint presentation on ZoomCharts, the world’s most interactive data visualization software that will support all your data presentation needs with incredible speed.
What is ZoomCharts?
What defines ZoomCharts advanced data visualization software? It is NOT another HTML5 charts library. It is:
- Interactive
- Fast
- Touch enabled
- Supports big data
A long time ago
DOS 6.2 allowed for:
- 320x240x8bpp
- Direct access to pixels on screen
- Assembler for performance
Today, the Web has finally caught up in the graphics department. Now, we have access to:
- Multiple browsers and rendering technologies
- Multiple resolutions
- Performance that varies by browser and device
Development setup:
- We write in JavaScript
- Commit to GitHub
- Build system in JavaScript
- Debug in Chrome
- Run automated tests
- Like WebStorm (and Vim)
Graphics:
Canvas (fast)
SVG (slow)
WebGL (>50%)
Interactive animations:
Zoom in and out of the graph, drag and drop data, all with your mouse or trackpad.
Graceful degradation:
High FPS (frames per second) lets you scale graphics with low image degradation.
Third party libraries:
- Raphael
- Hammer.js
- Leaflet
- Moment.js
Challenges:
- Responsive design: layouts can shift and look nice on desktop screens vs. not so nice on vertical, mobile screens
- Big screen resolutions: uses devicePixelRatio for sharp rendering, but no hardware acceleration beyond 2048x2048
- Safari compatibility: with 100% CPU, input events are blocked and browser locks up; strange code offers fixes
- HTML on canvas: DOM is slow; basic HTML markup must be parsed and rendered manually; text caching helps
Support:
- Process: TrialSupportBuy
- 1 day issue resolution
- #1 Tell me what I did wrong
- #2 Can you do…
Testing:
- Automated tests on every GIT push
Automatically:
- Compare images
- Record performance
- View errors in console
Interactive testing:
- Next step: record and playback
BrowserStack:
- Interactive mode
- Automated: Selenium API
Debugging:
Chrome Developer tools (F12)
- Debugging
- Profiling
- Timeline
Remote debugging available: developer.chrome.com/devtools/docs/remote-debugging
Future:
- More charts
- Extension API
- Memory allocation tracking
- WebGL
We are looking for statically-typed language:
- Error checking
- Performance
- Superior minification
- Easy to write and read
- Easy to call from JS
Building
Custom build script:
- Compile
- Minify
- Extract documentation
- Embed customer data

i made a complete mess developing this film.
this is the older emulsion of EIR film. i should have foreseen that it would be very fragile and tricky. i developed it like a classic E6, but obviously the temperature was too hot, and the film came out cooked. with one fingertip you could remove the emulsion from the base.
drying, the emulsion crumbled, as you can see.
if i'll ever find again another roll of this film, i would develop it in 20°c E6
C-41 stand developed -- Fuji 100 film shot at ISO 100 with Voigtlander Bessa T and mostly Voigtlander Nokton 40mm f/1.4 SC classic. This was a test of diluted (1:9) c-41, stand developed at room temp (75 degrees F), for 45 minutes with 2 inversions at 15 and 30 minute marks.
The negatives were a bit funky with a dirty grey mask. I had some problem getting a good image on VueScan for a jpeg scan, however the raw scans worked well in photoshop.
Dngs in photoshop were dull, like the mask, but auto leveling brought the colors right out correctly. I dont have as much hope if one were printing.
I will try this again, I am torn between increasing the development or adjusting the EI down for more light. We will see.
The two mountains and Brith Sholem were shot with a hexanon AR 57mm f/1.4 adapted to the Bessa. There seems to be some difference in how the light landed...
Bleached for 10 minutes at room temp with Potassium Ferricyanide bleach and fixed in home made Ammonium Thiosulfate fixer for 10 minutes.

Using pioneering new technologies in Superfoods and nutrition, CFTRI has developed amazing new products which are on show at CFTRI stall at Pragati Maidan:
· Chia and Quinoa based Chocolates and Laddoos;
· Omega-3 enriched ice-cream;
· Multigrain banana bar
· Fruit juice based carbonated drinks.
New Delhi, 24th November, 2016: CSIR-Central Food Technological Research Institute (CFTRI), the premier national institute for food technology is exhibiting a range of new agri-products now grown in India, called Superfoods that bring health and nutrition best practices to everyday eating and living to the common man. The exhibits by CFTRI at the Trade Fair at Pragati Maidan in New Delhi both impress and surprise with the range and scope of their utility and potency.
The Indian population is presently going through a nutrition transition and there is an increase in incidence of diabetes, impaired heart health and obesity while there is still rampant malnutrition in the nation.
Keeping in mind an effective solution needed to address these concerns, CSIR-CFTRI is working on bringing Superfoods to the Indian population. CFTRI works on various facets of food technology, food processing, advanced nutrition, Superfoods and allied sciences. Superfoods are foods which have superior nutrition profiles which upon regular consumption can help improve health and wellness of the consumer.
CFTRI has developed the agro-technology for growing Superfoods viz. Chia and Quinoa in Indian conditions. Chia is the richest source of omega-3 fats from a vegetarian source and Quinoa has excellent protein quality and low glycemic load carbohydrates. Comprehensively, Chia and Quinoa have potential to improve population health and both blend seamlessly into traditional food preparations.
CSIR-CFTRI also infuses the spirit of entrepreneurship in their students. One of the doctoral students after completing her academic program started her own technology provider start-up company, Oleome Biosolutions Pvt Ltd. In a global first, CSIR-CFTRI in collaboration with Oleome, has developed a 100% vegetarian, Omega-3-enriched Ice cream called “Nutriice” using Chia oil.
CSIR-CFTRI is also in the process of the final phase of testing of diacylglycerol (DAG) oil, a unique cooking oil that has “Anti-Obesity” functionalities. One can consume it as part of daily regular diet and while the oil is available as energy but does not get stored as fat in our bodies. The final phase of human clinical trial is presently under progress.
CFTRI has also designed and developed snacks with advanced nutrition designs to support the nutrition needs of growing children. These have been implemented in the aganwadi levels to complement the existing government mid-day meal and will be scaled up soon. The products, such as Nutri Chikki with spirulina, rice beverage mix, high protein rusk, energy food, nutri sprinkle, seasame paste and fortified mango bars have been well received by the children and the anganwadis alike. Multi-grain Banana bar is a new addition to in this product portfolio.
Another exciting area of multidisciplinary research being done at CSIR-CFTRI is on nanotechnology, food technology and nutrition. Nanomaterials are known for their characteristic properties and CSIR-CFTRI is working on the use of nanoparticles for various applications. One of our interesting developments is the design and development of food packaging material with nanoparticles with antimicrobial and antioxidant properties to improve shelf-life of processed foods.
CSIR-CFTRI is also working on “Smart Foods” to answer specific needs of the consumer. These promising and specifically designed innovations are being developed for better sleep, better skin health, improved digestion, better cognitive performance and better stress management. The high science is brought into a simple food product, like a cereal bar which helps one to be more attentive over the day, or a unique dosa mix that helps in working out better at the gym with lower perceived exhaustion and even a special soup to help sleep better at night!
Speaking on the sidelines of the CSIR-CFTRI exhibition at Pragati Maidn, Prof. Ram Rajasekharan, Director, CFTRI said “Our mandate is to find innovative solutions to India agricultural and nutritional challenges. Our aim is to develop products to make Indian agriculture productive, efficient and at a consumer level gradually replace drugs with foods that will promote better health and wellness. We strive to deliver our best in improving food security and nutrition security, also developing a stronger, smarter and healthier India”.

In 1951 Republic Aviation began a project to develop a supersonic tactical fighter-bomber to replace the F-84F. The result was the F-105 Thunderchief, later affectionately nicknamed the "Thud." The prototype YF-105A first flew in October 1955, but the first F-105D did not fly until June 1959. A total of 833 Thunderchiefs of all types were built, including 610 F-105Ds.
The U.S. Air Force sent F-105s to Southeast Asia shortly after the Tonkin Gulf incident in the summer of 1964. The USAF operated the F-105D extensively in the air campaign against North Vietnam called Rolling Thunder. Although designed as a nuclear strike aircraft, the F-105 could carry a total of over 12,000 pounds of conventional ordnance -- a heavier bomb load than a World War II B-17. The F-105 was gradually replaced by the F-4 Phantom, and the USAF withdrew the last F-105D from service in July 1980.

I'm developing a love/hate relationship with this tree. It's beautiful and sinuous and colorful and elegant, but it drops its crispy dead leaves all over the backyard all summer, and it sucks all the moisture out of the soil within a 10 yard radius. But just when I think it's more trouble than it's worth, I look up and its cinnamon colored bark, which is really just a skin, is giving way to the new growth underneath, which is my favorite color in the world, the shade of green that is new life. So the tree and I will work this out somehow.

Pike School of Art – Mississippi artists in residence for Fall 2015 were Samwell Freeman, Mackenzie Hoffman, and Keith Walsh. The residency took place from October 12, through October 25, 2015.
Samwell Freeman, a Computer Vision researcher at Apple, developing software for large-scale construction of 3D images, completed his Ph.D. in Computer Science at the City University of New York. He has taught math and programming courses and led workshops on interactive art, Arduino, and 3D printing at Alpha One Labs, a hacker space in Brooklyn.
During his residency, Freeman worked on an interactive video installation called Beautalyzer. Beautalyzer displays the output and inner workings of a viewer-taught algorithm, which tries to recognize the beauty of images. The installation is comprised of wall-mounted screens and a 3D printed interface. Machine learning is an increasingly important part of our lives, influencing the news we read, the people we meet, and the things we buy. The Beautalyzer hopes to open up this black box of artificial intelligence. What we find may be frightening or enchanting, demonic or hilarious; in any case, it offers us cybernetic insight into the nature of beauty.
The Beautalyzer project explores the potential for collaborative learning between people and machines. Viewers are given the responsibility to teach the algorithm what is beautiful, by labeling images according to their own aesthetic judgment. Simultaneously, viewers are shown vivid illustrations of the algorithm’s effects.
Mackenzie Hoffman is an interdisciplinary artist living in Los Angeles, CA. She received her B.A. in Studio Arts from the University of Southern California, where she was a recipient of the Handtmann Prize for Photography, as well as the Neely Macomber Travel Prize. She is an alumna of the Mountain School of Art, Los Angeles.
Hoffman uses photography and video to explore the construction of regional identities and their filmic representations, with a primary focus on the contemporary american South. Recent projects have described the gradual encroachment of social change within her multi-generational Southern white family, producing works that are both sympathetic and frustrated. She photographs provincial iconography, including the southern landscape, in an ongoing study of history, location and image.
Hoffman used her time at PSA-MS to further her interest in the present day physical and personal landscapes of the American South and to focus on new video work.
While at PSA-MS, Keith Walsh worked on a project titled “The SNCC Mounds,” a poetic interpolation of the legacy of the McComb-area Student Nonviolent Coordinating Committee (SNCC) engagements of the 1960s.
Walsh’s project continues his investigation of the Civil Rights and Black Panthers movements, within the larger geography of American liberation politics. The figure who links these two groups is the black SNCC activist Stokely Carmichael who, in 1964, was the full-time field organizer in Mississippi for the “Freedom Summer” voter registration drives, itinerant “freedom schools,” and protests. Various black residents, businesses, and churches in McComb housed or supported hundreds of SNCC and other civil rights workers during Freedom Summer and were met with repeated police arrests, neglect by governmental authorities, KKK cross-burnings and bombings. The firsthand experience of the sites, people, and histories within McComb were essential to developing Walsh’s project.
While in the region, Walsh conducted research at the Mississippi Department of Archives and History in Jackson, the state capital, and, in New Orleans; and visited cultural resources such as Hilda Casin’s Black History Gallery and met civil rights pioneer, Brenda Travis. To come to PSA-MS, Walsh won The School of the Museum of Fine Arts Boston, 2016 Traveling Fellowship. Walsh received his BFA from Hartford Art School, University of Hartford, West Hartford CT and a dual MFA from the School of the Museum of Fine Arts Boston and Tufts University, Boston.
Polish aid helped to develop agricultural cooperatives in difficult Palestinian conditions. Innovative solutions make it possible to cultivate vegetables without having access to agricultural land and with limited water resources. Crops are cultivated on the balconies, terraces and in the courtyards, and special attention is paid to optimal watering methods. / Dzięki polskiej pomocy w trudnych palestyńskich warunkach rozwijają się spółdzielnie rolnicze. Innowacyjność zastosowanych rozwiązań pozwala na uprawę warzyw bez dostępu do ziemi rolnej i przy niewielkich zasobach wody. Uprawy są zakładane na balkonach, podwórzach i tarasach, a szczególną wagę przywiązuje się do optymalnego sposobu ich nawadniania.

This is the rack which goes inside the Dallan Developing Tank. The 12 little arched frames each hold a sheet of film and are loaded in the dark, which, after I'd gotten the hang of it, became much easier than I expected. I'm guessing that the rack may have originally held 6.5 x 9 cm glass plate negatives for development.
I use this tank to develop 6.5 x 9 cm sheet film shot in my Kodak/Nagel Recomar 18.
In this shot, the Dallan film rack is posing on the home-made plywood tripod platform that i made for my box cameras.
Shot with Uncle Shoe's studio strobes in his studio. I also borrowed his Nikon FM2 for the shoot; shot on Kodak Portra 160VC.

Paxton's, Hornsby Westfield. They developed this roll of film. I was not satisfied. I won't be returning. Ultimately they were worse (yet $3.05 cheaper) than Camera House at Warringah Mall. There were water marks, specks, and scratch streaks running the length of the entire roll. Much, much more than what I've had in the past. More shockingly, though, was the fact that the woman retrieving my film from the machine right in front of me didn't even use any gloves!! Her fingers even ended up all over the emulsion itself. Completely shocking that these people (film developers in general) treat their customer's film with such disrespect. Honestly it's getting exhausting buying the expensive film, the expensive scanner, the expensive camera, lenses, and so on and so on.... All that just for the person developing your film to treat it like nothing. I had to quit repairing this picture, there were just too many water specks on it I had to give up..
