Windows 10 build 10162

July 20, 2015 — Alexey Ivanov

Release date of Windows 10, July 29, 2015, is getting closer.

I installed Windows 10 build 9841 in October 2014 as soon as Microsoft announced Windows Insiders program. Many things have changed since that time…

Yet I haven’t decided yet whether I want to change the usual Windows 7 to the new Windows 10. By the way, Microsoft offers free upgrade from Windows 7 SP1 and Windows 8.1 to Windows 10.

To experience the new OS better, I installed Windows 10 on desktop, more powerful than laptop. I used Windows 7 on this desktop since its release on October 22, 2009.

It took about 20 minutes to install Windows 10 build 10162 on the desktop, and about 10 minutes more to prepare the system for the first start.

After installation, you see usual Desktop with Start button on taskbar and with Start menu:

FloatCalc

February 27, 2015 — Alexey Ivanov

There’s a simple Java program FloatCalc.java:

public class FloatCalc {

    public static void main(String[] args) {
        System.out.println(1 - 0.56);
    }

}

What will be the output of this program?

Bonus question: Does the computation occur in run-time or compile-time?

Good Answer: Does Windows carriage return \r\n consist of two characters or one character?

November 24, 2014 — Alexey Ivanov

Recently I’ve earned silver badge:  Good Answer

This badge is awarded answers which have score of 25 or more. And my answer to question Does Windows carriage return \r\n consist of two characters or one character? has reached 25 upvotes.

Here’s my answer:

These are two characters:

  • \r is carriage return;
  • \n is line feed.

Two characters combined represent a new line on Windows. Whereas on Linux, \n represents new line. It moves cursor to the start of new line on Linux. On Windows, the cursor will stay at the same column in the console but on the next line.

\r on Linux has the same effect as on Windows: moves cursor to the start of the line. It is possible to print different information on the same line where \r is used instead of \n.

Russia goes to winter time

October 20, 2014 — Alexey Ivanov

After living for three years in “eternal” DST, on October 26, 2014, Russia will turn the clock 1 hour back to the standard, or winter, time.

Operating systems installed the corresponding updates. The time zone changed to UTC+3, and its title has RTZ 2 specification in parenthesis.

Windows 7 notifies: Daylight Saving Time ends on October 26, 2014 at 2:00. The clock is set to go back 1 hour at that time.

Copyright check

July 11, 2014 — Alexey Ivanov

A simple script to check whether the year in Copyright header is updated:

hg st -q -n | xargs grep Copyright | grep -v 2014

Nothing fancy! Just to save it.

It would be awesome if such a script updated the year automatically.

Advanced “status” options

March 31, 2014 — Alexey Ivanov

Two weeks ago I showed how to filter output of hg status with awk. That simple awk script removes unknown (untracked) files from output and also removes the file status: you get a simple list of modified/added files.

Actually, you can do this without using awk because Mercurial has advanced options for status command:

hg status --quiet --no-status

Or with short aliases:

hg st -q -n

The result is the same: you get the plain list of modified files, and files which are not under source control are ignored.
