In April this year I bought a Google Pixel 5 phone to replace my old Samsung Galaxy S7 . I was searching for a phone that has a small size but still all new features and good camera. The Pixel 5 was the ideal candidate, especially as its NFC sensor for Google Pay and my blood sugar sensor Freestyle Libre works much better. In addition the camera is producing fairly good pictures. The aluminium…
Don’t be afraid – Some clarification to common misunderstandings Since version 3.1, Apache Lucene and Solr use MMapDirectory by default on 64bit Windows and Solaris systems; since version 3.3 also for 64bit Linux systems. This change lead to some confusion among Lucene and Solr users, because suddenly their systems started to behave differently than in previous versions. On the Lucene and Solr…
Time for a tool to prevent any effects coming from them! Did you ever try to run software downloaded from the net on a computer with Turkish locale? I think most of you never did that. And if you ask Turkish IT specialists, they will tell you: “It is better to configure your computer using any other locale, but not tr_TR ”. I think you have no clue what I am talking about? Maybe this article gives…
Note: This blog post was originally posted on the SearchWorkings website . Since Day 1 Lucene exposed the two fundamental concepts of reading and writing an index directly through IndexReader & IndexWriter. However, the API didn’t reflect reality; from the IndexWriter perspective this was desirable but when reading the index this caused several problems in the past. In reality a Lucene index isn’t…
Last week, Oracle released Java 7 Update 2 , another milestone. This release included, of course, all the fixes that were already in Update 1 (see also Oracle's page ), especially those affecting Apache Lucene and Solr . Since my last post on this blog, I was investigating what changed and how other operating systems like Ubuntu/Redhat Linux and FreeBSD are supported (warning: sarcasm alert!)…
After the serious issues with the Java 7 GA release, Oracle released Update 1 of Java 7 yesterday. The first thing, of course, was to check the release notes, download the package, and finally run our Lucene test cases. When inspecting the download page and release notes on the Oracle web site, I got confused: The new release is Java 7u1 , in contrast the developer preview released one week ago…
Last week I visited the Gotocon Conference 2011 in Aarhus. I was invited by the Java User Group ( Javagruppen ) of Denmark to have a talk at their event during this conference. Of course this talk was about the famous Java 7 Launch Bug , I posted earlier in this blog. I started the trip on Monday morning and wanted to arrive in the afternoon but unfortunately the first train from Bremen to Hamburg…
I started this blog about two months ago, but until now, I had no time to write any posts. Since Oracle's release of Java 7 on Thursday last week, a lot of myths around the problem with Porter stemmer , wrong calculations in pulsing codec , and corrupt indexes appeared on the web. Some guys already blamed the Apache Software Foundation because they may have used the hype around Java 7 to fight…
