Alfred 3 workflow – Time Zone

Do you like Alfred? I like too… I’ve recently found bunch of very nice Workflows. For me, the most used one is for sure Time Zone.

The workflow has been created by Mr Carlos from New Zealand and published on the Alfred Forum. I’ve enhanced the workflow by adding a few new functionalities:

 

 

 

  • Migration to Alfred 3
  • Converting any time to all pre-defined time zones
  • Enabling 24-hrs time format
  • Displaying phone country code

After all it looks like below:

Conversion of a time in your local time to your pre-defined time-zones – “tz <time>” in formats HH, HHMM or HH:MM:

CarlosNZ, thanks for this great tool!

NoSQL: Exiting inner Replica loop with exception com.sleepycat.je.rep.RollbackProhibitedException

If a NoSQL Storage Node is not running for a while, after startup it may complaining:

2016-11-17 13:22:34.934 UTC WARNING [admin1] JE: Exiting inner Replica loop with exception com.sleepycat.je.rep.RollbackProhibitedException: (JE 6.4.15) 1(1):/opt/ece/data/nosql/storage2/kvroot/ECEStore/sn1/admin1/env Node 1(1):/opt/ece/data/nosql/storage2/kvroot/ECEStore/sn1/admin1/env must rollback 41 commits to the earliest point indicated by transaction id=-392 time=2016-11-17 14:18:53.969 vlsn=884 lsn=0x0/0x6e4be1 in order to rejoin the replication group, but the transaction rollback limit of 10 prohibits this. Either increase the property je.rep.txnRollbackLimit to a value larger than 10 to permit automatic rollback, or manually remove the problematic transactions. To do a manual removal, truncate the log to file 00000000.jdb, offset 0x6e4944, vlsn 881 using the directions in com.sleepycat.je.util.DbTruncateLog.  ROLLBACK_PROHIBITED: Node would like to roll back past committed transactions, but would exceed the limit specified by je.rep.txnRollbackLimit. Manual intervention required. Environment is invalid and must be closed.

From Drupal 6 to Drupal 8 and… finally at WordPress

Website update & engine refreshment (announced in Changes, changes post) took me really a lot of time (it might be 12-18 months or so). For whole this time I was scratching my head how to migrate old Drupal 6 with plenty of dirty configs to the latest & greatest version.


I’ve had plenty of attempts for migration, including Drush, Drupal migration plugin, even manual (!!) – in each of them, the result was not really satisfying:

 

  • Content and formatting was not migrating correctly
  • Multi-language pages made the migration tools totally confused

Time was flying and I couldn’t run away from buggy and insecure D6.

Changes, changes…

After years, significants changes on the site:

  • New domain! Finally, I managed to get my personal domain http://jhartman.pl hence I’m not tied to webd.pl
  • It turned out that it’s easier to migrate my old Drupal 6 to WordPress rather than to Drupal 8. Therefore I’m now on the new engine and so far I’m pretty happy
  • Attempted to AdSense, however Google is pretty picky and I’m not really sure if I will get approval
