  • 209,420,973 (+61,336,090) HTTP requests to our load balancer
  • 3,084,303,599,266 (+1,958,311,041,954) bytes (3.08 TB) total sent

Languages Translation (human and computer)

Languages - Google Translate: more tan 100 languages!
  • TYPE: Just use your keyboard.
  • TALK: Have a bilingual conversation.
  • SNAP: Translate images of text in a different language.
  • SEE: Use your phone’s camera to see instant translations.
  • WRITE: Draw letters or characters with your finger.
  • OFFLINE: Get text translations without a data connection.
Bing Translator

Great progress on a hard problem of translating human languages...
and very little progress on what should be easier: translating between programming languages. 
Even translating between .NET and JVM languages, that are using same byte-code, is rarely available and unreliable. An opportunity for Google (or Microsoft Research)?
The best hope may be JavaScript: there are compilers to JS for many languages... 
Ideally, there should be "semantic" translation from human languages to computer code (and reverse)
And then from "functional code" to "nice code" to "fast code"... 
Once automation starts, progress in SW will be much faster.

"Why are graphics better than text?
Novice programmers are fighting two battles at once: the fight to translate their ideas into logical statements, and the fight to keep the syntax legal. Blockly makes it completely impossible to make a syntax error. There are no unbalanced parentheses, no unescaped strings, no missing semicolons. Blockly allows novice programmers to concentrate on the logic.

Blockly has been under full-time development at Google since 2011."

Even .NET core is using LLVM for compiling to native code on Linux.
Apple's Swift language is created by Chris Lattner, same person who created LLVM.
And while Go and C# are still using GC even when compile to native code, 
Swift is using reference counting, that is more predictable than GC. 
Result: solid performance, so it may be a good language for sever and system programming also.
Even Rust is based on LLVM.

'Augmented Reality' phone: Google Tango + Lenovo

Lenovo aims to crack mainstream in July with new 'augmented reality' phone |
"China's Lenovo Group is ready to break into mature markets this summer with the launch of its new smartphone which sports "augmented reality" features developed under Google's Tango project, its chief executive said on Tuesday.
Project Tango combines 3D motion tracking with depth sensors to give a mobile device the ability to know where it is and how it moves through an area, creating the potential to use augmented reality features on the phone.
Augmented reality software then overlays text or graphics on the real-life image. It differs from virtual reality, which seels to simulate real-world views."

A few extra cameras on the phone:
Lenovo will launch a new smartphone which sports 'augmented reality' features developed under Google's Tango project in July.

IoT Printers with Amazon Dash

Samsung printers automatically re-order ink with Amazon Dash
"Amazon didn't stop at handy buttons for its Dash re-ordering tech. Back in January, the company announced a collection of devices that leverage the system to automatically order supplies when you're running low. That lineup includes a number of printers from Brother that take care of ink refills when levels begin to disappear. Amazon has now added four Samsung printers to the fold, tapping Dash Replenishment to make sure you're able to continue putting ink to paper as needed."

"After purchasing one of the four Samsung printers, you can tell the device to monitor the ink levels and re-order from Amazon should the need arise."

"The key feature of the Cat S60 is its miniature thermal imaging camera based on the FLIR Lepton sensor (with 80×60 active pixels). The camera, which highlights temperature contrasts, can be used to identify over-heating electrical appliances and circuitry (or just check which computer components are the hottest ones and measure their actual temperature using a special application), detect heat loss around windows and doors, spot moisture and missing insulation and even see in complete darkness... The Cat S60 smartphone is based on the octo-core Qualcomm Snapdragon 617 system-on-chip... the smartphone can withstand drops onto concrete from up to 1.8 meters (MIL Spec 810G) and can even be used underwater (up to five meters depth) for one hour."

Microsoft Azure IoT Hub Reaches General Availability
"Microsoft has recently announced its Azure IoT Hub offering has reached general availability (GA)...
Azure IoT Hub is one of the foundational services that make up the Azure IoT Suite. The Azure IoT Hub service provides bi-directional communication between devices and the cloud. Devices may connect through a local field gateway when internet connectivity may not be available on the device or when a device only communicates in unsupported protocols such as ZigBee or Modbus. The field gateway, in turn, will communicate with the IoT Hub Cloud gateway. Alternatively, if a device supports HTTP(S) 1.1, MQTT 3.1.1 or AMQP 1.0 it can natively communicate with the IoT Hub Cloud gateway. Device SDKs are available for C/C#, Java, and JavaScript/Node.js."

Azure: DateTimeOffset

Many of Azure storage APIs are using DateTimeOffset .NET type instead of usual DateTime.
That structure includes UTC times and local offset to UTC

Choosing Between DateTime, DateTimeOffset, TimeSpan, and TimeZoneInfo @ MSDN

datetimeoffset (Transact-SQL)
Storage size: 10 bytes, fixed is the default with the default of 100ns fractional second precision

course: Date and Time Fundamentals | Pluralsight

c# - DateTime vs DateTimeOffset - Stack Overflow
Instantaneous Time vs Calendar Time Visualization
"If you ever need to modify a previously recorded DateTimeOffset - you don't have enough information in the offset alone to ensure that the new offset is still relevant for the user. You must also store a timezone identifier (think - I need the name of that camera so I can take a new picture even if the position has changed).

It should also be pointed out that Noda Time has a representation called ZonedDateTime for this, while the .Net base class library does not have anything similar. You would need to store both a DateTimeOffset and a TimeZoneInfo.Id value."

book: The 8th Habit by Stephen Covey

The 8th Habit - Wikipedia, the free encyclopedia
"The 8th Habit: From Effectiveness to Greatness is a book written by Stephen R. Covey, published in 2004.[1] It is an upgrade of The Seven Habits of Highly Effective People, first published in 1989. As such, it clarifies and reinforces Covey's earlier declaration that "Interdependence is a higher value than independence."

The eighth habit is "Find your voice and inspire others to find theirs."
Voice is Covey's code for "unique personal significance."
Those who inspire others to find theirs are the leaders needed now and for the future, according to Covey."

For Impact Ideas | For Impact | The Suddes Group
"‘VOICE’ is about unique, personal significance! Covey says, “VOICE lies at the nexus of 

  • Talent (your natural gifts and strengths,
     'what you are good at') plus 
  • Passion (those things that naturally energize, excite, motivate and inspire you,
     'what you like doing'), 
  • Need (including 'what the world needs' enough to pay you for) and 
  • Conscious (small voice within that assures you of 'what is right' and prompts you to actually do it).”


There are 4 dimensions to human nature: capabilities, needs, intelligence
  • body (need)
  • mind (talent)
  • hart (passion)
  • spirit (conscience)
People can discover their voice because of the three gifts everyone is born with:
  1. The freedom to choose
  2. The natural laws or principles – those that dictate the consequences of behavior. Positive consequences come from fairness, kindness, respect, honesty, integrity, service and contribution
  3. The four intelligences – mental, physical, emotional and spiritual.

Yet, in spite of the ubiquity of the phenomenon, there is no word for the exact opposite of fragile. Let us call it antifragile. Antifragility is beyond resilience or robustness. The resilient resists shocks and stays the same; the antifragile gets better"

R for SQL Server 2016 (and Oracle)

R for SQL Server 2016

"The R programming language ... has become an industry standard for statistical analysis with nearly a dozen graphical interfaces as well as packages for various IDEs and text editors.

Commercial support for R is offered by Revolution Analytics, ... company recently acquired by Microsoft as part of their big data and machine learning initiatives. The result of this acquisition is support for R in the upcoming SQL Server 2016.

...With R running in the database, you eliminate the performance hit normally associated with moving the data from your DB server to your R server. ...

The gateway for this is sp_execute_external_script. This stored procedure allows you to pipe data from SQL Server to R using standard queries. An R variable, usually a data frame, can likewise be returned back to SQL Server upon completion of the R script.

... a plugin model for other scripting languages will be offered."

There is a similar integration for Oracle DB also:

R Enterprise @ Oracle
"Oracle R Enterprise, a component of the Oracle Advanced Analytics Option, makes the open source R statistical programming language and environment ready for the enterprise and big data. Designed for problems involving large volumes of data, Oracle R Enterprise integrates R with Oracle Database.

Rules for successful presentations

James Whittaker: How to change the way people think in four easy steps

"Rule #1: Come out swinging"
"The only time people will ever give you their attention –
 where you don’t have to earn it, they just give it to you –
 is the first 30 seconds of a presentation.”

Rule #1.5: "Attention span interlude"
“Every six minutes, include something of high interest.
That’s the length of the average human attention span.”

Rule #2: "Know your 'shit'"
“People connect with speakers who have passion –
who are really in love with their subject.
You inherit some of that love from them.”

Rule #3: "Make it Epic"
“Albert Einstein said, 

‘Great spirits have always encountered violent opposition from mediocre minds.’
Quote powerful people.
You can assume some of the power of those you quote.”

Rule #4: "Be brief. Be bright. Be gone."
“Avoid long and tiresome summaries.”
