24TH JUNE, LONDON – The London Python User Group meetup at Skills Matter for a talk by Antonio Cavallo introducing debug in Python. Introducing three debuggers pdb, winpdb and gdb and their use to debug simple crashing python applications at both python code and C level. See the SkillsCast (film, code, slides) at: skillsmatter.com/podcast/java-jee/intro-to-python-debug/m...

I'm trying to debug Apple's SceneKit (because crashes are reported from within the SceneKit binaries) and found a way to show Flatland with normals, which is a way of saying Flatland is showing which part of each point on the surface is perpendicular to the surface. It's pretty, but disappointing I have to resort to this to get my program to work.
Just before returning the debugging system (it was too expensive to keep ;-) ), I unmounted all parts. Seperating CPU and cooler seems to be a dirty matter: The thermal conductance paste is very viscid.
Enabling PWM for the backlight pin seems to mux *all* PWM pins to PWM mode, which isn't good if you're using them in GPIO mode already to toggle other logic
24TH JUNE, LONDON – The London Python User Group meetup at Skills Matter for a talk by Antonio Cavallo introducing debug in Python. Introducing three debuggers pdb, winpdb and gdb and their use to debug simple crashing python applications at both python code and C level.

The bus driver for the IEEE-488 data bus lines was connected directly to the MCU at the old petSD. At the new petSD-duo on the other side, they're connected via a port expander that is attached via SPI to the MCU. The serial transfer over SPI takes of course some time and this broke everything! Had a hard time while debugging but things look good now :)

2017臺北國際動漫節第五日下午B舞臺，東立出版社＜Debug─筆電的使用手冊外傳小說~山櫻樹下的幻想奇譚＞作者草子信與插繪nyaroro簽名會。由於夜排、插隊（臺灣俗呼「解壓縮」）嚴重，下午2點30分活動開始前東立出版社工作人員要求重排，領號碼牌過程中發生推擠衝突，有書迷因而負傷，事後東立出版社在官方臉書上公開致歉。攝影者拍攝時遭工作人員制止，當時不解其故，回家後查新聞方知。

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

Over forty pre-made indicators are great but every user is unique, this is why the TraderStar offers programmers to create their own indicators in Java-Script, to perfect it in the built-in debugger and test it with historical data. If you do not have programming skills, you can order an indicator at the Neonway service center (www.neonway.com/service).
GNU gdb 6.8-debian
Eclipse 3.3.2
On further tests, we now think Kdevelop is faster and more stable.

The voltage regulator built into the Freescale K20 parts seems to be very sensitive to shorting on the 5V line. Here we lifted the pins for the input regulator and the output, to confirm that it is the regulator that was malfunctioning.
