Lepi a múlt héten tartott az Inetpub tagoknak előadást és éles rendszeren bemutatót a clusterekről. Egy bosszantó software hiba miatt - Lepi szerint "Úgy látom, hogy a szoftver kissé bugos." - kevésbé finom lélek - pl. én - a Gödöllei féle nagyszótárból, vagy a Magyar Tengerész Káromkodások c. kiadványokból ordítottam volna idézeteket.
Lepi 3 elődásának ppt formátumú vázlatai a http://www.box.net/public/0ykdcma1vb#main helyen láthatóak.
Mindenki sajnálhatja, hogy nincs hang. Mi - jelenlévők - előadását lenyűgözve hallgattuk. Köztudott belepofázásunkat és vitázó hajlamunkat nem a mikrofon jelenléte, hanem az előadás magas színvonala tartotta kordában.

Jon Galloway írta IE7 Standalone Launcher updated for RC1 tárgyú bejegyzésében, hogy a http://tredosoft.com/IE7_standalone oldalon részletesen leírja Junfeng Zhang, hogyan is működik e dolog:
Why run Internet Explorer 7 Release Candidate 1 in standalone mode?
Maybe you are a web developer who wants to test his/her designs on IE7 but want to keep Internet Explorer 6 until Microsoft releases the final version. It's basically a way of running IE7 and IE6 at the same time without having to overwrite the previous version.
What does the program do?
"IE7s.exe" will create a .exe.local file (if you're interested, read Junfeng Zhang's blog post for more information about the .local file). After that it will add values to more than a thousand registry keys in your Windows Registry. Internet Explorer 7 should start then. 10 seconds later the program will perform a cleanup, remove all the registry keys and close itself. It is OK to run multiple instances at once.
A dolog lényege Junfeng Zhang's blog post-jában van:
DotLocal (.local) Dll Redirection
If you are developing software on Microsoft Windows platform, you probably have heard of the term “Dll Hell”.
“Dll Hell” happens when two applications install two incompatible versions of a shared dll. Since there is no versioning control for dll in Windows, the second copy may overwrite the first copy. As a result, the first application will not function any more.
Since LoadLibrary will search the application directory first, among other things, a workaround for the “Dll Hell” is to carry the “shared” dll with the application, which effectively makes the “shared” dll private.
But there is another kind of “Dll Hell” which can not be easily worked around. And this is COM.
If two incompatible versions of a COM server is installed and registered, even the two COM servers may reside physically in different location, there is only one place to register the COM server. Hence only the latest registered COM server will be activated. This is essentially another manifest of the “Dll Hell” problem.
To workaround this problem, a “Dll redirection” mechanism is introduced in Windows 2000.
For an application foo.exe, if there is a file foo.exe.local exists, Windows will first look at foo.exe’s application directory, before start the regular dll search. To mitigate the COM problem, the redirection applies both to full path dll loading, as well as partial name loading.
In Windows XP and Windows Server 2003, the behavior of DotLocal(.local) is altered a little bit. If foo.exe.local is a file, Windows will keep the same behavior as Windows 2000. But if foo.exe.local is a directory, Windows will search foo.exe.local directory for the dll, instead of the application directory.
In Windows XP and above, Windows (via fusion team) introduced a new side by side programming model for application isolation. This model essentially is the same model introduced in .Net framework (with no surprise, as both models are designed by the same team, with small variances based on the need of the specific product). In Windows the metadata is stored in a XML file (typically called a manifest file), as opposite to the assembly binary in .Net framework.
Since the side by side isolation model is a logic evolution of the DotLocal(.local) dll redirect, in Windows XP and Windows Server 2003, when there is an application manifest (foo.exe.manifest, or a Win32 resource of ID RT_MANIFEST, Type 1), the DotLocal dll redirection is disabled.
It turns out the DotLocal(.local) dll redirection has a huge value in private testing. When developing a new version of the COM server, you don’t really want to mess up with the one in system. If you can redirect the dll to a private version for a set of specified applications, and let other applications use the system one, it will be the best of all the world. And DotLocal(.local) provides exactly that, with the exception that if the application has a manifest, DotLocal(.local) dll redirect is disabled.
Így megoldódott a végleges IE6 és az IE7 RC1 egymás mellett futásának korrekt lehetősége. Nincs "Dll Hell".
A fejlesztők örülhetnek.
(Már aki nem tudta magának ezt megcsinálni.
Lásd:"After that it will add values to more than a thousand registry keys in your Windows Registry."
Nos ezek vannak döntő többségben.)

Currently Listening ver 1.5 out now.
Yep, updating again today. I just felt like adding Winamp support, so it's been added. There are some caveats to this though. I basically use the same technique that everyone (I'm assuming) else uses to try and get the Winamp information. Unfortunately that means no Album name data. I know it sucks but really you should upgrade your media player anyway, Winamp is so 1990's.

ALL PCs with the Centrino logo or any computer using an Intel Wireless Ethernet adapter must update their PROSet software and drivers found here. An update was released earlier this month but that version was found to leak memory and cause PC slowdown. It is absolutely critical for IT departments and individual users to update their PROSet software and drivers. Get tips and links for the update here!

Ron Oglesby írt egy érdekes cikket Brian Madden oldalán.
Ebben szó esik a hardware virtualizációról, de nem történik említés az Intel által kidolgozott EFI szabványról.
Erről írtam korábban:
More Power to Firmware, majd
FW: Linux beats Windows to Intel iMac,
Intel Macs May Boot Windows XP After All,
:-(( UEFI - Microsoft Shuts Windows on New PC Firmware
A legutóbbi hivatkozásomban írt cikkből egy most is fontosnak tartott dolgot szeretnék kiemelni:
UEFI, ironically, supports the Microsoft plan. The firmware was designed to work with both 32-bit and 64-bit operating systems and to be backward-compatible with OSes designed to work with BIOS—on the desktop, the bulk of the OSes which will be used are 32-bits—using a special Software Compatibility Module to emulate BIOS functions.
Too many versions of Vista? Read more here.
Thus, UEFI Forum members, which include Microsoft, Intel, Advanced Micro Devices, Dell, Hewlett-Packard and BIOS makers American Megatrends, Insyde Technologies and Phoenix Technologies, agreed to focus on delivering 64-bit UEFI implementations in PCs, using compatibility modules as a bridge to non-EFI OSes, a person familiar with the matter said.
Véleményem szerint nem új fogalmakat kéne bevezetni, hanem a már elfogadott szabványok szerint kell dolgozni. A virtualizáció és sok egyéb dolog könnyebben mehetne.
A WLW gyors elérése fontos, ezért
soulposition [at_sign] msn dizzot com kitalálta a
Live Writer System Tray kisalkalmazást. Nos ez nem gyors elérés.
Helyette javaslom az RBTray használatát. A leírásból:
You can download RBTray 3.2 from this link
RBTray 3.2

Allows you to minimize windows in the tray area on taskbar by clicking right mouse button on the window's minimize/close box or from system menu or from window's system menu (+). Allows to set any window in "Always on top" state from window's system menu.
Más kérdés, hogy a WLW betöltése is lehetne eleve gyorsabb.
Az RBTray általánosan alkalmazható.
Kiegészítés (2006.08.28, 13:19):
LiveWriter OnScreen jobb, mint a Live Writer System Tray, de a betöltés sebességén nem javít(hat).
LiveWriter OnScreen is free. Free as in free beer, not as in freedom.
Its free today, free tomorrow and free forever.
You need to install LiveWriter before you install LiveWriter OnScreen.
see the help for details.
Néhány elem nem installálódik,
ergo nem is megy a My Feeds-ből a WLW-be insert. A képeket meg mindig új post-ba akarja illeszteni. A Spot viszont jó, ha nincs Screen Capture 2 .
Egy jó elképzelés, módosítani és aktualizálni kéne az IE7 RC1-re is.
Az MSTechToday weblogjában láttam ezt a hivatkozást egy tweak guide-ra, innen:
Windows Vista Pre-RC1 (5536) Guide
Written by Chris Holmes, Dena Reiter and Kristan Kenney
http://www.longhornblogs.com
Introduction And Overview
Windows Vista Build 5536 has been released to beta testers. This is the first build that truly shows what Windows Vista is capable of, and shows a great deal of improvement over previous builds. It is also “Pre-RC 1”, meaning that it is a preview of what we can expect in Windows Vista Release Candidate 1 (RC1).
This build introduces a lot of performance fixes and offers greater stability overall. The installation process is much quicker on most machines, and some people have even gotten the much desired 15-minute installation times.
As this build is a preview of Release Candidate 1, it is stable and usable on a day-to-day basis for most people. However, there are some things that you may find negatively impacts your experience with Windows Vista, and this guide outlines some of these things as well as how to remedy these issues.
Egyes javaslatok (disable UAC), nyilván akkor hasznosak, ha végleges verzióról van szó és power user-ek vagyunk. Esetleg, ha mást akarunk kipróbálni.
Nyilván nem azért lát az ITember (nem tudom, hogy az előember-ember-utóember sorban hol a helye?) egy beharangozottan biztonságosabb, stabilabb oprendszer használatához, hogy ezen előnyöket hirtelen negligálja.
Ettől függetlenül hasznos útmutató.
A Microsoft TechNet-en új fórumot találtam (2006.0305.23-án nyílt) a fenti címmel.
Biztosan gyakran látogatom meg.
Matthew Broersma, Techworld 25 August 2006:
Gartner predicts move toward modular OS.
Vista will be the last version of Windows that exists in its current, monolithic form, according to Gartner.
A cikkből továbbá:
Instead, the research firm predicts, Microsoft will be forced to migrate Windows to a modular architecture tied together through hardware-supported virtualisation. "The current, integrated architecture of Microsoft Windows is unsustainable - for enterprises and for Microsoft," wrote Gartner analysts Brian Gammage, Michael Silver and David Mitchell Smith.
The problem is that the operating system's increasing complexity is making it ever more difficult for enterprises to implement migrations, and impossible for Microsoft to release regular updates. This, in turn, stands in the way of Microsoft's efforts to push companies to subscription licensing.
The answer, according to Gartner, is virtualisation, which is built into newer chips from Intel and AMD, and has become mainstream for x86 servers through the efforts of VMware. "Once Windows includes virtualisation at its core, we expect OS development to change direction from integration to modularisation," the analysts wrote.
Kiemeltem a fontosnak tartott részeket.
Örülök, hogy mások is úgy tartják (nem csak én a többi pihent emberrel együtt), hogy a moduláris rendszerek fejlesztése a cél, mert ily módon lehet a folyamatosan változó számítási igényeket, üzemeltetési követelményeket kielégíteni.
Továbbá ekkor jöhet el a szép új világ a server alapú grid computing, hogy
Lepenye Tamás költői kérdése választ kaphasson.
Szerintem minden IT embert érintő dologról van szó, jó megközelítése a címben foglaltaknak.
Walt Mossberg of the Wall Street Journal takes tech questions from readers each week and publishes his answers in Mossberg's Mailbox. In this week's column, he tackles a question I get asked all the time. How do you set up a new computer for a relative who is an enthusiastic Internet user but is naive or technically unsophisticated?
I set my parents up with a new Dell PC, and included antispyware software that I run periodically to clean up the computer. I recently discovered they had more than 200 instances of spyware on the machine. This may be because my 81-year-old father surfs porn sites ALL the time (this isn't a joke). Is there any way to keep his computer bulletproof and safe?
OK, first of all, Dad's probably more typical than you might think.

Több kérdést tesznek fel az accept-álás után, mint a Longhorn-nál.

Egy blogban hivatkoznak erre a forrásra: Kevin Mitnick creampied by Pakistani rage.
A group of Pakistani crackers vandalized today the websites of 4 different Kevin Mitnick's ventures, in what it looks like to be a focused personal attack. The sites defensivethinking.com, mitsec.com, kevinmitnick.com and mitnicksecurity.com have been defaced with offensive messages against his person.
A konkrét linkeket én jelöltem be az eredeti szövegbe azért, hogy mindenki megnézhesse, mivel is foglalkozik jelenleg az "infamous cracker"-nek titulált zseni.
A hivatkozott blogból:
"It is kind of stupid, they do it for the attention," Mitnick said. "When I was a hacker, I never stooped to defacing sites because that was more like vandalism, that wasn't any fun. It is more about getting in and being stealth and looking around and exploring."
Ezzel teljesen egyetértek.
