I want to be your next #FediHire ! I've been a programmer since 1985 (as a child), I've been an IT professional since 1995 (pulling wires and swapping cards and configuring MS Windows). I graduated from University of Arkansas Fayetteville with a BS in CS in December of 2003. A full resume is available.

I currently require a 100% remote position. I cannot relocate from Cove, #Arkansas. I would prefer W-2 employment with a base salary of at least 130k USD/yr, plus some sort of retirement offering (401k or similar) and healthcare benefits (HDCP + HSA or similar).

I prefer something where I can be a high-performing individual contributor: reading, writing and improving source text the majority of my day, with some time spent knowledge-sharing with other developers -- learning and teaching. I'd like to work with #Haskell, #Purescript, or #Idris as the primary source language. I've previously delivered value in Haskell, #Javascript, #SQL, #Python, #Scala, #Java, #C, and #C++ among others. I can be productive in almost any language (no PHP, please; I promised myself never again).

Over the past seven months I've been working on improving the support for FreeBSD in OpenJDK, sponsored by the @FreeBSD Foundation.

==============================
Test summary
==============================
   TEST                                              TOTAL  PASS  FAIL ERROR  SKIP
>> jtreg:test/hotspot/jtreg:tier1                     3033  2720     9     0   304 <<
==============================

It's been an interesting, and very educational ride. Some of those tests were pretty easy wins, but some required delving deep into the internals of both OpenJDK and FreeBSD, as well as getting acquainted with the basics of the ARM architecture and instruction set. (Remembering how fascinated I was when the Acorn Archimedes was launched, I'd say this was long overdue!)

I finally feel that the OpenJDK BSD port is nearing a state where it makes sense to try to upstream it, and get it fully integrated into the OpenJDK infrastructure and build/test/CI frameworks. There's still a lot of work remaining to get there, it has to be done in portions and with the cooperation of the upstream project, but I hope to be able to spend the next six months or so to get there.

Thanks a lot to the welcoming and supportive OpenJDK developer community, as well as the @FreeBSD Foundation and the people there for sponsoring and supporting the project, and for providing help and insights about the FreeBSD internals when I got stuck.

Преодоление сложности в самом сердце Анемичной Модели

Доброго времени суток, Хабр! Сегодня хотел бы поговорить об анемичной модели — одном из самых дискуссионных топиков (особенно для приверженцев DDD) и о том, как, по моему мнению, правильно её готовить. Для кого-то анемичная модель — это антипаттерн, тогда как для других это единственный правильный способ реализации приложений. Многие использовали её годами и даже не знали, как она называется, и что кем-то она считается антипаттерном. Реальность же такова, что анемичная модель — это инструмент, который может подходить или не подходить в зависимости от ситуации, но при этом является очень популярным и, по факту, «стандартом де-факто» для многих программистов и организаций. Хотя в последние годы я и вижу тенденцию к тому, что DDD и, соответственно, богатая доменная модель становятся всё популярнее, пока что, по моему мнению, им далеко до популярности анемичной модели.

#Introduction

Hello, my name is Christoff.

I live in Illinois, USA, outside the St. Louis area. Below I'll talk about my technology and creative interests, and a bit about me personally. I'm going to hashtag the heck out of this post.

the whole "deadbeef" thing is the magic number from #Solaris for freed memory. I simply chose .monster TLD because it seemed cool and I like "extended" TLDs.

#Technology

I have been using a OpenBSD, #NetBSD, or #GNU/#Linux since the late 1990s as a primary workstation. I used macOS from 2020 to 2025, switching to the #KDE neon distro (KDE plasma is amazing and KDE isn't bloated anymore, yay!).

My current career is as a #pentester where I break into web applications, IP networks, mobile applications (especially #Android), and people to their face or over the phone; code #malware; write documentation; and enjoy helping clients in a third party contractor/consultant role. I started that job change in 2020, when I earned the #OSCP certification at the height of "#infosec twitter" when I did well there.

Previously I worked for about 20 years as a senior-level programmer, and systems, infrastructure, and database administrator. Burnout was very real and I was extremely bored/unfulfilled.

Now that programming and sysadmin stuff isn't my career, I find I enjoy programming and tinkering again.

I am a big fan of NetBSD and always have been. I am not a huge fan of GNU/Linux but I do appreciate things "just working", even if it is full of closed-source binary blobs and other garbage. It was fun in the 1990s.

I know many programming languages but have been paid professionally to code in #C, #Perl, #Python, #PHP, #Java, and #Groovy for big commercial entities like eBay, small companies, and the US government.

I've maintained 99.99% uptime for a 60MM+ platform for years, including failover and backups (that were regularly tested... you test your failover and backups, right?!).

I always wanted to be a cool C and low-level programmer, which I thought for the longest time was being a kernel programmer, but now I know that isn't the life for me.

Emacs is something I've enjoyed since the beginning and I still can't code a #Lisp well. I'd love to be a cool #lisper with #CommonLisp, but haven't gotten there yet. I'm on the #c64 and #embedded #retrocomputing train now.

#Creative

For creative stuff, I aim to do a lot but tend to hop around as interests take me. I could use some discipline there (someday?).

For #music, I have an electric #bass (Fender Jazz) and electric #guitar. I love #jambands (#GratefulDead, #Phish, #Goose) and that's the type of music I like to play along to.

For #art, I like #acrylic and #watercolor painting. I rarely do it, but think about it a lot and love it when I do it. I don't have any skill or talent, but that's not the point. It's for me and no one else.

For #computing, I am venturing into #C64 #demoscene programming and exploration. Not only was I too poor to get one when I was little but I sorta forgot about it over time. The desire to do cool things in a restricted environment where folks are playing in the sandbox, too, is very exciting and attractive to me. I don't know how to code the #Commodore64 stuff yet, but will! Learning the assembly language (I have zero desire to code in BASIC again and I can just code assembly).

#Personal

I live with my soulmate and our five amazing cats in a small town outside St. Louis living a quiet life. Just doing our jobs, taking care of daily life stuff, and enjoying each other and life as much as we can. Ups and downs of life chaos, like anyone else, but we're doing alright!

We enjoy exploring places within driving distance and there are a lot of places to go to.

Currently, we're really into playing two-player games together and just started collecting #boardgames. Right now, we're really digging #SkyTeam, #RoyalGameOfUr, #ForrestShuffle, #SentinelsOfTheMultiverse, and this magnet game I don't know the name of. We have #SpiritIsland and #ArcNova to unwrap and learn. We tried really really hard to get into #ArkhamHorrorTheCardGame but the rules are too complicated and confusing, where it felt like we were doing the wrong thing all the time.

I am 46. I grew up loving Star Wars, Star Trek, #SciFi, reading novels non-stop, horror, and watching movies. I collect classic SciFi books from 1960s and 1970s.

I would perhaps describe myself as an extremely curious person, that loves #puzzles and #mysteries, #exploration, figuring out #HumanBehavior like I'm an alien studying humans (I'm good at it, it turns out), that has a keen eye for detail, remembering random little things, and a good listener. I'm fairly adaptable and fluid in most things, which works well for me. My brain works differently than a lot of people, and while frustrating a lot of the time for things I don't understand fully, it is me and serves me well in niches.

Making people laugh makes me happy. I am a #hacker and #tinkerer.

In case you missed it, last week we released Spring Boot 3.3.13 (last 3.3 OSS release), 3.4.7 and 3.5.3 (please don't use 3.5.1 and 3.5.2).

@elricofmelnibone

Well, my reality is fortunately the one where one looks around and observes what is actually happening.

In this the observable reality, the jobs want .NET and C♯ because that's what's in use, and no-one wants Java anywhere near like they used to because the promised world where Java was everywhere, from applets in our WWW browsers to applications on our desktops running out of the box on all sorts of processors, with none of this emulating ARM on AMD infrastructure needed, simply has not materialized.

Indeed, sometimes the Java postings are bait-and-switch for C♯; because the pimps just generalize OOP.

The language with so much promise all of those years ago, went to die at #Oracle.

I remember the days when Java was the thing of the future that everyone was surely going to be using instead of all of that C and C++. We were going to have safe sandboxed Java in our WWW browsers, to do away with ActiveX et al..

But even in those days I said that #Oracle was where software goes to die. Clearly Oracle is milking #Java to death.

Which is a bit of a shame.

In the meantime, Microsoft is pushing .NET 8 and no recruiter has Java skills on their checklist.

Oh boy, this is gonna be fun.

I need to parse #CSV in #Java. Parsing it into String[][] is easy enough, but here's the hard part: I also need to parse the numbers in the CSV file (into a double, BigDecimal, or the like), and those numbers could be formatted in any of the myriad number/currency formats that Excel might produce.

Web searching isn't getting me very far, and Excel itself is of course closed source so I can't look there.

Any advice would be much appreciated!
