I recently found myself having the need to revoke an old certificate. The steps are actually quite straightforward, but you do need to have your old revocation certificate to hand.

Simple follow these steps. In a terminal, issue:
That’s it!
My eyes have been opened to yet another case of foul play by a megacorp.
As if their package management isn’t disgusting enough
(www.theregister.co.uk/2008/07/23/enormouse/), /their BIOS
configuration on laptops of the recent few years leaves MUCH to be desired.
On the bottom of my HP Compaq 6715b laptop is a removable panel which
covers a memory slot and a Mini-PCI-E connector. “Great”, I thought,
having a non-functioning Broadcom card in there, “I’m going to install
an Intel 4925 AGN wireless card here because it’s supported by the
firmware/kernel I use (CentOS 5.3) – and I’m loath to building a new
kernel when I can just plug in a new card ;-)”.
My card, £15 off Ebay, arrived this morning and I carefully fitted it.
Booted the machine, went into the BIOS settings to ensure it was
enabled, and…. wait a minute, it isn’t listed. Perhaps it’s broken…
or …perhaps HP have imposed a blacklist of vendors/subsystems which
THEY don’t allow to be recognised in MY computer. Not listed in lspci,
nor dmesg… basically nowhere.
Is this legal? Did I ever see any restriction declared ANYWHERE before
buying this machine that stated “HP retains sole right to how this
machine is used and with what”..?
What point is there putting this restriction in?! Someone buying a
budget laptop isn’t going to source their over-priced parts from the
OEM! Why, darn it, why?!
If you have – or rather, are thinking of buying an HP, Dell or IBM
laptop, I’d suggest reading these first:

I’ve thought about actually re-flashing my BIOS with modified code,
partly out of sheer bloody-mindedness towards HP (oh, and I would
publish, intricately, the solution), and partly just out of the
practical need for wireless networking. But now, I’m just baffled by
the whole thing.
Hilariously, as a final insult, the latest BIOS update from HP for my
machine, “updates the Computrace OPTION ROM to version 866”. So…
you’re telling me I have this “Computrace OPTION ROM” installed, huh?

Is there no goodness left in the world? Can old ladies not be helped
across the road any more? MUST we buy battery hen eggs instead of free
range?! Like, where’s the love, man..?
Yes, it seems too good to be true.
Well, guess what?! It IS!!
That’s right. Your old tat (or, you could say, my old tat) is just about as worthless to everyone else as it is to me. I’ve spent ages on ebay and sold almost nothing. And what I have sold, I sold for 99p.
Give to charity instead, that’s what I should have done! Pah!
🙂
Does it actually help?
Anyway, too much PHP development going on currently to really give it much thought. That’s the problem – what pills can you take (metaphorically speaking) to speed up work?
So… sometimes I wonder, what’s the point? I add a bookmark, and the Firefox plug-in asks me if I want to add it to delicious, so generally I say yes as I think it’s probably useful to others. But, syncing with delicious doesn’t seem to retain the organisation I give to my bookmarks (they are my bookmarks, after all).
I have installed xMarks to Firefox, which is great. Delicious, on the other hand… it’s not Digg… what is it?

Ok, I had to do it. I think I know what I’ll be doing in May.

AMD demos its upcoming six-core 45nm Opteron™ processor, codenamed Istanbul. Except it’s doing so with a 4 CPU machine – giving 24 cores! Just what could you do with all of that parallelism (not on a server)?

When most of us talk digital cameras, we talk megapixels, ISO, image noise, shot-per-second speed and image processing. We’re tech geeks. But really, none of that stuff matters as much as your camera’s lens.

No doubt open-source proponents will rejoice over this news: The British government has decided to increase its use of open-source software in the public services field. It will be adopted over Windows whenever it delivers the best value for the money. Schools, govenment offices and public agencies will all give open source a new look.
