Designing and constructing mostly Java-based systems from embedded/real-time world to large/distributed/cluster server systems.Hacking low level Linux stuff, like device drivers, kernel modifications, and virtual machine instances.Some sysadmin (BOFH) things like openvpn, certificates, tape robots, fibre channel, shell and perl scripting etc.RHV installation architecture and installation. Fixing RHV (through vaccination scripts, injective virtual machine)Projects for companies, organizations, GOV + MIL, etc.Constructing, designing, buying and documenting server rooms. Doing cost calculations, but still don't like too much "paper work".Configuring switches, like HP (+VC), Cisco, Brocade, Dell. Ethernet and Fibre Channel.Other activities like:- buyer - mainly HP enterprise class servers, including blades, and components.- head hunter- SCSTBasically doing everything from chip/embedded component level through programming to higher level combined system architecture.2015q4 working with: IBM POWER8, oVirt, RHV, RHEL, SVC, Brocade FCSee also: http://www.lemmke.org/arl/products/index.4.en.html#on-going_projectsManaged to escape Peter's Principle.CDD project: my function was to create Java-based OS on top of highly optimized Linux distribution I constructed. Also MVB field bus simulation and later actual implementation on displays. Constructed UI object integration to fieldbus using XML as middleware and XSL to construct actual Java code, so that just changing a jar one had different role for a display. Also designed proportional based UI display based on my earlier research at HUT.

Running a datacenter in Helsinki Pitajanmaki.--- Operations & Planning.--- Virtualizing: managing virtualization/cloud environments.--- Storages: designing, building, maintaining and planning storages (FC,SCST,Ceph)--- Networking: managing Ethernet switches and HP virtual connects.--- Storage Networking: managing FC swithes and Ethernet-based storage networks.--- Customer deployment and provisioning.--- Buyer: buying hardware needed.--- Everything else. what ever it takes to run a data center.--- +arlslab2012-10-01 fully operational.

Presenting Linux history and current trends and problemsLike to provide lectures like: "Why do people program sh*tty code".Some people have asked so informing you openly that Linux nor WWW has provided me 0 (zero) IPOs.

Solving (minor) technical Linux/Java-related problems.Netorek HC data center: Building (buying,configuring) hardware for the system. Constructing infrastructure. Our own data center is for and serving http://www.vihta.com/ needs.Around half of the Finns at some point use Vihta without even knowing it.See more about vihta: http://www.vihta.com/en/

Personal (BYOD) testing laboratory - testing technologies and feasibility.!!! Most likely absolutely the largest BYOD in whole world !!!Testing systems like:- Brocade switches- SCST- IBM blades (have around 10 enclosures)- IBM Power systems (have POWER4 to POWER9 machines)- HPE blades (have around 4 cabinets)Have around 25 rack cabinets full of different systems for testing!Getting hardware from arlslab sponsors, and buying additional components with my own money.Testing technologies:- fiber storage systems (SCST, IBM SVC, IBM DS, HP EVA, HP MSA)- distributed storages (Ceph)- fieldbuses (KNX,MVB etc.)- PLC like Simatic (todo)- virtualization systems (KVM,libvirt,RHV/oVirt etc.)- cloud systems- IBM Power Systems (POWER6,POWER7,POWER8,POWER9)- data center technologies- IPA and IdMs- Ansible and Puppet- various blades- Elasticsearch- VPN- and naturally everything LinuxHands-on tuning. From CPU and memory installation to higher level systems.Constant learning. Always on-line (irc: arl)Read more: http://www.arl.fi/lab/Disobey event in Finland is run on arlslab hardware. Thank you sponsors.Or use Google+ (before G+ is there):- arlslab @ Google+ https://plus.google.com/communities/117151719987566997360and- arlslab oVirt: https://plus.google.com/communities/116940840837288674806- arlslab IBM Power: https://plus.google.com/communities/118077731961971546784- arlslab SCST: https://plus.google.com/communities/105588080843696272235This is my way to avoid Peter's Principle. [http://en.wikipedia.org/wiki/Peter_Principle]And while you reached this far: Why not donate hardware to arlslab?

Customer projects (java-based webcam server, xsl:fo coding, etc.)

- Software projects for customers, mainly Java, SQL, etc.- Linux supportDid work as fireman style .. quick learn in, did my job and fast exit. With a reasonably high consultancy fee.Experince: Java, Javascript, JSP, HTML/CSS, XML, Unix sysadmin/BofH, TCP/IP, network management, Various data bases/SQL/functions/optimizing, like Oracle, Solid, Informix.Said "no" for position to be Regex Germany CEO.Left because the company grew too fast and people around me started to fight for positions and leaders did not lead.

- ISP operations- Linux VAR (Hardware)- Linux development- International Linux support (software/hardware)- developed multiple Linux distributions for customers.Xgateway Finland Ltd. (XGW) was the world's first Linux company.XGW used my Linux version 0.03 mobos from 1991.

Forced Linus to release the thing named as Linux.Highly influenced Linus to release Linux using first GNUish later GNU license.Running Linux since it was installable (0.02-0.03).Created Linux Activists mailing list. (LA was supported by HUT Comp Sci Lab)Created Usenet groups alt.os.linux and comp.os.linux.Released various Linux-related documents.Speaker at various events.Distributed Linux-knowledge openly.CEO and CTO at World's First Linux-based Company.Released huge amount of computers free by installing (and porting) Linux.Search IMDB for documentaries.Constructed 2 different Linux distributions. (one for embedded, one generic).

Did evangelical missionary work for WWW for couple of years during the youth of the project.- http://www.w3.org/People.html‎- http://www.w3.org/Tools/findrefs.pl.html- Erwise- ...

- UI development/research projects- Unix systems porting (multiple Unices, ~30), Cubix- additionally course assistant vacations (Operating systems, etc.)- teaching occasionally as an sssistant or the full course (Computer architecture)Experience: Perl 4, Perl 5, C, C++, sh/csh,tcsh scripts, emacs, elisp, X10, X11, assembler (various), Lisp, HP/UX, BSD, AIX, Unix sysadmin/BofH, Sun 2, Sun 3, Vax 750, HP 9000.Left because of my half year trip to Australia - driving around the east cost, locations like Sydney, Brisbane, Cairns, Eula, Lightning Ridge.
