revanx_··on John Carmack about open source and anti-AI activists
He's anything but stupid, he is also human, makes mistakes (like you) and the last time I checked he was working on AI for years now so, yeah, he's probably going to gravitate towards "AI good" instead of "AI took my job".
revanx_··on Gaming on Linux has never been more approachable
There is no "real" GPU virtualization available for regular consumer, as both AMD and NVIDIA are gatekeeping it for their server oriented gpus. This is the same story with Intel gatekeeping ECC ram for decades.

Even if you run games in container you still need to expose the DRM char/block device if you want vulkan,opengl to actually work.

revanx_··on Ask HN: Anyone else use FreePascal as their low level language?
You are wrong, Pascal has always allowed pure raw pointer and data manipulation as well as self memory management, the strong type enforcement and auto management for some types (strings, dynamic arrays) is just on the surface so you don't shoot yourself in the foot but it never stops you from doing any low level programming.
revanx_··on Raspberry Pi 5
sounds like it's designed to be that way, yes.
revanx_··on Raspberry Pi 5
They announce the product but you can't even pre-order it, a typical pi experience.
revanx_··on Health Services as Credence Goods: a Field Experiment (2020)
I used to have a lot of cavities due to poor oral hygiene, after I had a complications with my wisdom tooth, I really decided to step up my game and take care of my teeth. Brush 3 times per day, 15 minutes after every meal. Floss two times per day. Reduce soda intake. Reduce sugar intake.

Cavity free for 4 years now. I switched dentist and after several visists she accused me of seeing another dentist because I didn't have any new cavities. Anyway ...

revanx_··on Delphi VCL and FMX Libraries for Python
> I think, much like even-versioned releases of Delphi -- which were famously half-baked and buggy, and you'd inevitably end up dealing with a confluence of bugs until the odd-released version came out a year or two later

I still remember, like some XE(n) version had a really unstable ide/debugger and they didn't even bother fixing it, you had to wait till the next version was released (and you had to pay for it) for the bug to be fixed. There was even some guy that decompiled the ide and offered free fixes online for some more annoying bugs.

revanx_··on A guided intro to the Free Pascal language
nothing magic about Result keyword, it's just an implicit pointer, you can avoid it completely by using explicit pointers.
revanx_··on Threadripper 7000 Storm Peak CPU Surfaces with 64 Zen 4 Cores
Imho if cpu manufacturers figure out how to slap a large cache on the same die (something like amd 3D V-Cache but much more) we may actually see graphic cards become obsolete in favor of software rendering.
revanx_··on Some CyberPower UPSes may pose a fire hazard
I just took apart my unit CP1300EPFCLCD and it indeed has the yellow silicone. There's also a lot of white silicone but only to keep wires in place.

My solution is to just inspect the unit every once a year to see if any yellow glue is turning brown just like in the video. Meh ...

Edit: A closer look showed that some parts of the glue already turned brown. It seems to be affected by heat because the parts that are brown are the parts making direct contact with the board/components.

revanx_··on Some CyberPower UPSes may pose a fire hazard
no it doesn't. It just shows the location where you can find the glue. How do you actually remove it? Do you soke it in ethanol and pick it apart or how ?
revanx_··on Some CyberPower UPSes may pose a fire hazard
so how do you go about removing/cleaning that glue?
revanx_··on Some CyberPower UPSes may pose a fire hazard
true, surge protectors are actual snake oil. 99% of people get em thinking it will protect em from lightning strikes ...
revanx_··on Some CyberPower UPSes may pose a fire hazard
How do you achieve the X <= 10 ms switching capacity? You need this if you actually want your equipment to survive the power outage.

Also, I'm extremely sensitive to humm noise output by inverters so I can only tolerate UPSs that have that "Green mode" option which (I guess?) powers directly from AC when under quality power but still provides protection.

revanx_··on Some CyberPower UPSes may pose a fire hazard
I had to place my unit (CP1300EPFCLCD) in an empty room for 2 weeks to let it out-gass, the smell of plastic was unbarable and was not suitable for living conditions. I found others complain on the web just as well.

After two weeks I measured the amount of VOC in the room for a couple of hours and there was still some presence but nothing to worry about.

Overall the unit works as intended ...

revanx_··on Cloudflare had a partial outage
This was very educational, all of a sudden I couldn't reach 60% of all websites I normally visit everyday. I guess this is the cost of laziness under the guise of DDOS protection.
revanx_··on Lazarus – Professional Free Pascal Rad IDE
This is because some major refactoring has to happen in RTTI and system units to support dynamic linking so that true delphi-style runtime dynamic packages can be supported. This is easier said then done because of how many platforms are supported by FPC & Lazarus.

In contrast, Delphi IDE only runs on windows ...

revanx_··on Lazarus – Professional Free Pascal Rad IDE
I use the synopse mORMot library for server side rendering http server and database access. It has well written documentation with lots of examples on how to get started. IF you have any questions I am free to answer them.

revanx_··on It’s Still Stupidly, Difficult to Buy a ‘Dumb’ TV
I bought a 58 inch samsung tv in 2016 for around 250 euro. 1080p, barebone no smart features, two hdmi ports and two usb 2.0 ports. I wouldn't give it up even if someone payed me double today. It works as intended and that's all I care about. I use it daily. Yes, color vise it's a TN lcd panel so about as good as it can be expected but none of that matters because you simply get used to it.

I haven't checked but I think you could probably still find something bare-bone today it's just that people want the greatest shit and don't want to settle for less. Maybe try something that isn't OLED or 4K and you might be surprised...

revanx_··on Bottles – Run Windows software and games on Linux
thank you for that link. Does AMD have the same shenanigans of locking out consumer grade gpu's? Intel has GVT-g vGPU virtualization which works with intel integrated graphics, it will be interesting to see what road Intel takes with their dedicated GPUs.
revanx_··on Bottles – Run Windows software and games on Linux
I game on linux, it's not as secure as I would like it to be. I run everything under unprivileged container including steam, the problem is that for vulkan hardware renderer to work it requires direct access to the device and the linux kernel doesn't virtualize device access. It's a security nightmare as far as I can see.
revanx_··on Microsoft's Activision Blizzard deal is bad for privacy rights
I'm in EU, I was able to completely delete my entire battle.net account two weeks ago, (active since 2005) just by going to the support page and filling some web form. No ID photo required. Once you send that, you get an email confirmation and unless you cancel the request, your account will be permanently deleted in a few days.
revanx_··on Systemd 250 Released
I wish Systemd-networkd had native PPPoE support.

https://github.com/systemd/systemd/issues/481

Still, systemd is just great and it has made my life a lot easier.

revanx_··on Linux Hardening Guide
iptables and nftables both have ways to declare rules for interfaces that come and go. Identifying dynamic interfaces is done by string comparison instead of by index (for static interfaces).
revanx_··on Linux Hardening Guide
thank you for the follow up. You have made some good points but I couldn't find any explanation to what you said : systemd talking to the network before I even have the client firewall up.
revanx_··on Linux Hardening Guide
I see, I've heard about it but I couldn't find any reference that systemd starts listening on sockets before the firewall service is started. Even if it did, with systemd you can setup your firewall service to start before the eth link goes up.
revanx_··on Linux Hardening Guide
What do you mean it talks to the network? Can you give some reference?

revanx_··on Dusk is a 90s style shooter from the mind of a teenager (2016)
What I miss in modern games is the unique textures that old games have. Just lookup "Sacrifice" game on steam. There's so much post-processing crap in modern games that it sucks out all the life from a game.
