![Secure Boot Certificates Expiring 2026 – Part 2 [Sinchen Rant]](/data/attachments/576/576410-f92c7f31a6c1ad48ec206d0153d46ac6.jpg?hash=qGIKLo7uWN)
In April I published a short rant about the… let’s say sub-optimal situation regarding expiration of certain certificates. Nobody could have expected that this would happen some day. When Microsoft created certificates with 15 year validity in 2011 there was no need to think of expiration...
With the release of yet another – this time very easily exploitable – vulnerability in the TPM-only configuration of BitLocker it should be obvious to switch to a stronger setting.
Despite the announcement that there might (for once) also be a loophole for TPM+PIN mode, I doubt an enhanced PIN...
Those Secure Boot certificates that are about to expire in June and October 2026… that is pure chaos. They started migrating three months before the deadline… Now that was fast →🐌🐌🐌
What exactly is the impact of the expired certificates? What to do? Contradicting information on various sites...
Windows "Device Encryption" With Automatic Unlock Is Not Secure Enough
An easy explanation avoiding technical terms (until the spoiler at the very end)
The Short Version
If your PC meets certain criteria Windows encrypts your files automatically. This is good! But the way it's set up by default...
GBAtemp was an important part of and an anchor point in my life during the past few years. This is a reason to express my explicit gratitude.
Thank you, admins! Thank you, staff!
As mentioned in an earlier entry, there is not much to do for me anymore.
In view of the repeated slight and subtle...
![Eat s…, Samsung [Sinchen Rant, ≈320KB pictures]](/data/attachments/519/519991-3cddd9e2b1b805f26e28aaf8efeaee77.jpg?hash=bGlaJy8odG)
Rant part
Recently I got aware of Samsung preventing bootloader unlock world wide with One UI 8. Despite not being affected (my newest Samsung device is from 2020, has reached official end of life and is very far from having One UI 8) this made my blood pressure rise to unhealthy regions once...
![HP xw6400 Workstation [Pictures about 1.2MB]](/data/attachments/517/517503-f0389ea063e54ec11c1d0af141b034ac.jpg?hash=5hCSA0JAKf)
Last Saturday I got lucky on the fleamarket for the first time this year. For just 10€ I got an old HP Workstation. If I had to guess I would associate the hardware with the year 2007.
The small tower case is of high quality and pretty heavy. It could be an excellent basis for building a...
Sorry, this is not a well-written text.
Currently I'm pondering whether I should continue supporting GBAtemp financially. For years this was a no-brainer. Last October was the first time I had a some doubts, but a few days after the account upgrade expired I felt very bad for using the site...
Noticed that I've lately become the target of low effort and low quality mockery, hostility, teasing. These attacks are done walking right at the edge to harassment/bullying without crossing the boarder in an obvious way.
I must be doing something damn right if I'm worthy of being attacked...
Usually one would assume a smartphone zombie isn't worth mentioning. They are everywhere and this behavior is socially accepted. I on the other hand will never get used to the stupidity addicts show outside while walking, cycling or even driving a motorized vehicle.
One example that goes far...
Heat wave, drought
Unfortunately, I can't avoid watering the garden. Tomatoes, beans, peas, strawberries, lettuce and a few potatoes. Quite a lot of work lugging watering cans upstairs.
So little Sina simply takes a garden hose and starts watering her kitchen garden. After a minute or so, there...
Well not really an Apple store, but a reseller featuring only Apple products. Other than the legal difference (not a shop run by Apple) there is probably nothing really different. For simplicity I’ll just go with “Apple store” from now on.
In my effort of improving computer security and moving...
This is a Sinchen Rant → I will not write a well expressed essay with tons of logical lines of thought but express my personal opinion with a minimum of reasoning. Everything below that line is based on plain ol’ life experience of mine (and of many others I know/knew).
I’ve had this touched...
After months of gradually getting used to Qubes OS, I'm now finally ready to use it as my main system.
The amount of compartmentalization achieved by this operating system is stunning! But despite all the separation everything stays seamless on the desktop – as if it was a single physical...
Sometimes I feel the need to reply something but can't without going fully off-topic in a thread. This means: Welcome to another lengthy blog entry nobody will read after I spent a lot of time writing it. :)
Freedom comes at a price
I’m an advocate for having full control over the own computers...
I've opened that thing and removed a ton of disgusting dust/dirt. I didn't take any pictures of the inside because of 🤮
But the real problems were the AUX in jack and all the buttons on the top. AUX jack had broken solder joints which just needed a reflow. :)
A simple connector inconveniently...
I’ve said this a few times before and I say it again:
Energy efficiency of smartphones is dreadful!
People simply accepted that they have to recharge their phones frequently even when not in active use. Pretty much everybody bought this. But it is still just wrong and idiotic! Early 2000s...
Recently I found a very cheap fire and water resistant metal box for securing documents and to a lesser extent electronic data storage media. The cheap wafer lock "securing" my not-a-safe would open up if the LockPickingLawyer just looked at it once with a disappointed face. It is not an...
What a pain it is buying from the Google Play Store!
(They don't want my money)
Castlevania – Symphony of the Night is an excellent game for PlayStation 1. Sadly the original CD is one of those titles nobody in their right mind would buy right now – especially the PAL version.
I heard it had...
