Ha egy ilyen To Do List-em lenne, elmennék nyaralni, mert vagy elintéződik magától, vagy bedől az oldala, de a vége nem látszik.

A megtermelt pénz így válhat közhasznúvá. (ugyan elég körülményes a megfelelő Activex-ek installálása, de megéri). Sohasem látott dolgok kerülhetnek nagyszerű bemutatásra. Az eredmény: http://ttp.bl.uk/collections/treasures/leonardo/leonardo_broadband.htm?top

After some years of false starts and false hopes, storage virtualization, also known as block virtualization, is finally proving its worth. All the major vendors have embraced it, most notably IBM, EMC, and HDS (Hitachi Data Systems); the solutions themselves have improved; and customers, typically large shops managing large SANs with intense data availability requirements, understand how to deploy it and where to get good ROI. No longer a technology in search of a problem, storage virtualization offers a way to address a wide range of storage management woes.

No, mindenkinek kezébe került az IBM kb 30 évvel ezelőtti dokumentációja a mainframe-ek op.rendszereinek működéséről. Lassan keresztbe-kasul virtualizálunk eltérő platformokat (mint egy "rendes" hippy communában), a lényeg azonban, hogy egy op.rendszer alapvető része a virtualizálás (bármely alkalmazás virtuális gépként, sajátos környezetben működik) mintha elveszne.

http://www.pcworld.com/article/id,128888-c,vistalonghorn/article.html elképzeléseivel az IBM announcement-et. A vágy és a tett esete.
"We're going to look at a fundamental piece of enabling technology. Maybe its hypervisors, I don't know what it is," he said. "Maybe it's a new user interface paradigm for consumers."
"It's too early for me to talk about it," he added. "But over the next few months I think you're going to start hearing more and more."
Quoting from the IBM official announcement:
The IBM secure hypervisor architecture, or "sHype," is a Research technology designed to run in conjunction with commercial and open source hypervisors that control servers and data in a shared environment. sHype aims to provide a security "wrapper" around distributed workloads in the data center, extending mainframe-like security to pooled data and resources across multiple IBM and non-IBM systems.
sHype is designed to bring stronger security guarantees to popular x86 and blade servers. As is increasingly common, IBM Research developed the sHype technology not just in its own labs, but implementing early versions of sHype with customers to test and evaluate the code. Additionally, portions of sHype have been contributed to the Open Source community and are being used, for example, as part of the open source Xen hypervisor kernel.
...
sHype works in conjunction with hypervisors by establishing a virtual machine to act as a data center "security foreman." The foreman uses preset configurations, business policies and exceptions set by the customer to lock down all content of the data center. It then automatically sets policies that evaluate, rank and code workloads as well as the physical and virtual resources needed to run each workload. Once workloads and resources are locked together, the integrity of the data and resources is assured and can be better managed by hypervisors accordingly...

Derekas méretű hosts file-ok (pl.: a hpHOSTS 59,279 host nevet tartalmaz). w2k és xp esetében, ha nem tesszük disable állapotba a DNS client service-t, akkor jelentős lassulást okozhat a nagyméretű host file. w9x és home esetében nem. Vista esetében csak administrator-i joggal lehet a hosts file-t módosítani.
Ezeket az host neveket számos szűrőprogram is vizsgálja, szűri (AD Muncher, SpywareBlaster, stb.).
Külön mise, hogy a hazai gané oldalak nem szerepelnek a listában.
Lassacskán felmerülhet a kérdés, mennyiért védekezünk és mi ellen?

IBM pioneered virtualization 40 years ago with mainframes. Since that time the technology has been ported to x86 market, mainly thanks to the effort of VMware.
Now that virtual machines are revolutioning the whole IT industry, IBM is demonstrating its experience putting huge efforts in hypervisors (Virtualization Engine and Xen), management tools (Virtualization Manager and Tivoli Usage and Accounting Manager), desktop solutions (Virtualized Hosted Client Infrastructure), and benchmarking (vConsolidate) development.
virtualization.info met Rob Sauerwalt, Global Brand Manager for IBM System x, to discuss about current company involvement in virtualization and his point of view about raising market trends like virtual appliances and application virtualization in an exclusive interview.
