Hi there.

I’m using the Plantronics BackBeat Sense headset for the complete three weeks and have only positive feelings.

The design and materials are great! The headset is so well constructed, that you easily forget it is on your head. The sound is super cool, way better than “Beats” one. I’m working in an open space and still isn’t disconnected even in a separate block ~60m from my workplace. The lifetime is about a 2,5 days of 6–7 hours listening, which is also great.

Definitely would recommend!

I’ve decided to refresh my knowledge and read the JVM and Java Language specs (SE 8) one more time. I will post a bunch of questions and answers on each chapter in a series of Medium posts.

This is the second part, which covers the Chapter 3: Compiling for the JVM

See the first one.

1. Why pushing the int values ‘3’ and ‘7’ to the method operand stack will be represented by a different optcodes in the bytecode? ‘iconst_3’ and ‘bipush 7’ respectively.
2. How many local variables will be used in the bytecode for the next statement ‘int i=100; double…

Hi there.

I’ve decided to refresh my knowledge and read the JVM and Java Language specs (SE 8) one more time. I will post a bunch of questions and answers on each chapter in a series of Medium posts.

The first one is for the Chapter 2: The Structure of the JVM

1. What happens if the thread stack reached it’s maximum?
2. How many stacks may each thread have?
3. In which case number in JVM would not be equal to itself?
4. Where is the method area memory allocated?
5. What is the first value in a frame runtime variables array?
6. What would…

Hi there.

On Monday I bought a Lenovo t460s and it is a terrific machine!

The build quality, perfomance, screen — just super good.

But not without a rain in my parade :(

Actually, I’m the stupid one here — I didn’t noticed that the keyboard is not a US or UK QWERTY, but a slightly different one.

It’s Danish!

Not a big deal, though… But how do you guys live with a Ctrl+Alt+2 for the @ ? I guess there are statistically less Danish Java developers, couse it’s a pain to type an annotation sign :)

I’ve finished a Coursera GCP Fundamentals course and have an opinion to share.

During the last year, I’ve learned a thing or two about the Google Cloud Platform. The main source for me was a GCP podcast, which I would recommend to subscribe to. Yesterday I’ve recieved a promo voucher to try the courcera course for the GCP newcomers.

If you are new to the Google Cloud — the course is one of the best starting points. …

Hey!

If you like awesome pictures of adorable animals then probably you already know that there is a subreddit with tons of such pictures https://www.reddit.com/r/aww/

While watching a cat sitting like a human, I’ve asked myself if it is possible to find out who is cuter: cats or dogs.

Turns out it’s not a big deal if you have access to the Google Cloud.

The plan:

1. Get 500 latest images from https://www.reddit.com/r/aww/
2. Send them to the Cloud Vision API and get labels back
3. Count the labels for cats and dogs
4. PROFIT!

Luckily Felipe Hoffa already provided reddit’s dataset, so we…

The concept is rather hard to understand without visualization.

The gif below makes it easier when using it with the original paper.
