marak830··on Deutsche Bahn "joke" is no longer funny
As someone who has been riding trains to YOK every day for the last 5 years. I don't agree, unless you mean by partially late 1 minute.

I'll admit I rarely take trains that are not on the JR line - so perhaps you're referencing them? Either way I can generally time leaving home and returning home to within 3-4 minutes every day.

marak830··on Show HN: Lofi Cities – Pixel-art city nights with browser-generated lofi
Not the biggest issue (and perhaps the smallest) it's not Sakura tree season here in Tokyo ;)
marak830··on Show HN: My Claude quota ran out in 10 minutes, so I made a tool to find out why
I set it up and saw the token notifier down the bottom slowly ticking up. I'll try again and report back, perhaps I misread something? I was surprised something like thst (which I assumed was an API call) was trickling token usage.
marak830··on Show HN: OpenTIE and OpenXWA, Modern Ports of Tie Fighter and X-Wing Alliance
Indeed! We purchased that after we finished the first two, and they have been having a ball of a time.
marak830··on Show HN: OpenTIE and OpenXWA, Modern Ports of Tie Fighter and X-Wing Alliance
I recently setup an emulator, passed it through the TV and had blue tooth controllers hooked up, so I could show my son Donkey Kong Country - we ended up finishing 1 and 2 (with my wife joining in), he loved the older game. Trying to get him into older PC games now. So yeah, it is possible to get them into it (just dragging him away from minecraft is hard haha).
marak830··on Aphantasia Beginner's Guide
I have Aphantasia, as well as excellent map reading skills and spatial awareness. BUT I'm pretty sure that spatial awareness is something I developed when cheffing (needing to know where things were rapidly) and map reading I attribute to video games (specifically doom originally haha).

A) Oh nice! that's cool

B) Warning everyone, it slowly eats tokens - If you're like me and on the pro plan, perhaps not a good idea to have its (albeit slow) drain on the tokens.

marak830··on An Engineer's Old Cooking Trick Is Going Viral, Divides the Internet
(former chef here) - I've been writing my personal recipes like this for 20+ years. Mostly because I can grok the steps from memory so I can skip that part (other times I just write the spec step between the curly bracers).

Not the neatest, but my 'Dad's cookbook' isn't really read by anyone except myself when asking the family what they want me to prep on the weekend for the week.

marak830··on Illinois just passed a law that puts Linux on the hook for age verification
I would argue the reason is so people can make arguments like yours.

Step 1: get easily passed, simple looking laws passed to 'protect the children' Step 2: 'oh look at all these people bypassing the law. It's so simple for a child to watch porn with this.' Step 3: increase the requirements bit by bit on the verification

By letting something simple pass, they can claim it's not thst bad, and anyone who argues against it is being hyperbolic.

marak830··on Responding to the next frontier of critical cyber capabilities
Tinfoil hat, are they and anthropic doing this deliberately to increase the chance of the US govt licking down foreign models(well attempting, we all know how badly that will work).

Or they just are truly that incompetent.

marak830··on Zero-Mem: Zero-Token Memory Operations for LLM Agents
I was doing something similar where I saved user input/model output in a multi-depth node style storage system (each depth having more precise details) with the focus on the model having accurate user fed information. I was mostly focused on retrieval of accurate / useful information based on user query (injecting the database node as additional, high confidence information)

Once this(Zero-mem) passes it's peer review, I may have to see if my system can handle something similar instead/in addition.

I'm quite excited to see growth in these different ways of eliminating token's.

Long winded aside, @langs, have you published your work on this?

marak830··on Decades-old fish sauce at abandoned factory in Canada finally being removed
"The value on the market [was] about three million dollars, but they would not let us sell it. And for that reason, we just [left] it there.”"

I think that's the point OP is pointing out, for better or worse (for what it's worth I believe "He suggests that a prior conflict with the CFIA over product labeling motivated them to close the factory before the inspection began" may be correct).

A company should have plans for cleaning up their product before just walking away and leaving other people to clean up their mess.

Maybe it's rather naive of me, but that's what I believe.

marak830··on Qwen3.8-Max: A New Bar for Coding and Cowork
I'm oh so seriously tempted to switch at least for a month or two.
marak830··on Show HN: Gander, an Android file viewer that asks for no permissions
Christ that's depressing.

I'm assuming that all works even with application sandboxing (1) or am I mis-reading how that is applied to applications.

Man I need to move my movement to GrapheneOS up to be sooner.

marak830··on LegacyHive: Windows user profile service arbitrary hive load elevation of priv
NightCrawler released another window's vuln.

From what I can understand of it:

* Read the target user's NTUSER.DAT hive into memory as a backup.

* Open the hive offline using the Offline Registry (offreg) API.

* Modify HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Local AppData to point at \\.\GlobalRoot\BaseNamedObjects\Restricted.

* Save the modified hive and replace the original NTUSER.DAT.

* Copy the user's UsrClass.dat into the temporary working directory.

* Acquire a batch oplock on the copied UsrClass.dat to synchronize execution with profile loading.

* Start a suspended process using CreateProcessWithLogonW(..., LOGON_WITH_PROFILE, ...), triggering the User Profile Service to load the profile.

* Wait for the oplock to break when Windows attempts to access UsrClass.dat

marak830··on Ask HN: What was the last task where only a frontier model could do it?
Oh cool thanks for the link. I look forward to reading through it. (I've noped out of discord after their ID demands though, never using them again.)
marak830··on Ask HN: What was the last task where only a frontier model could do it?
If you did a write up of that I would be very interested. I assume a lot of others would be as well.
marak830··on GitLost: We Tricked GitHub's AI Agent into Leaking Private Repos
Good read thanks.

Also interesting to see who coined the term prompt injection.

marak830··on GitLost: We Tricked GitHub's AI Agent into Leaking Private Repos
You know what? I had honestly forgotten about that xD. /thread
marak830··on GitLost: We Tricked GitHub's AI Agent into Leaking Private Repos
Who thought having a LLM with access to private information, with public access to ask it questions, would ever be a secure process?

Look I like interacting with these tools as much as the next guy, but I'm certainly not going to trust them with access to information and then allow anyone to send them prompts.

Edit/further thoughts: So (assumable as they said this is disclosed with github's knowledge) this has been patched. But how many different word combinations will it take to find another way to have this occur?

marak830··on We Are the Last People Who Know How It Works
I don't think they will be jumping anywhere TBH.

(young-un with the 28.8k starter here, so I just need some stretching to keep up with you old fellas :P)

marak830··on Windows 11 users are tired of MS account requirements creeping into everything
Yeah, their performance has gone in the toilet. Recently we needed an old system setup just for group meetings in the office. I installed 11 on it - it struggled, gave up, threw a linux install on for giggles and it's buttery smooth.
marak830··on Local Qwen isn't a worse Opus, it's a different tool
GLM 5.2 came out today and the early reports have been quite good. Very difficult to run except on prosumer hardware, but small business could quite easily (or something like open router).
marak830··on Windows 11 users are tired of MS account requirements creeping into everything
Yup, Windows 10 LTSC here. It's a lot faster and smoother, but I'm already transitioning to Linux on my other boxes. Will probably move before LTSC runs out as well.

edit: I realised I overplayed how much faster and smoother it is. compared to standard win 10 or 11. Example being my login screen sometimes struggles to come up when the computer is locked (work around double mash CTRL-ALT-DEL)

marak830··on Ask HN: What are tools you have made for yourself since the advent of AI?
I bashed out a dashboard for myself the other month, monitors firewall alerts/warnings/shows connected devices, process monitors on a few pc's that I keep an eye on, a to-do list/calendar combination that let's me track some internal tasks I need to do weekly, bi-weekly, monthly, etc, oh and it pings cloudflare to keep me up to date on the website stats. And an Amidakuji game to help me and another staff member pick who's doing X task that day :P

Nothing major, and only works with my infra, but it saves me a few minutes a few times a day to just be able to check the tab, and if there's an alert load up the full stats page.

marak830··on I analysed 20 years of my chats
Oh I mis-understood, I thought the drive was encrypted not the chats.

From my understanding of their encryption, you could brute force the password. It's AES-128 I think? So might take a while xD

marak830··on I analysed 20 years of my chats
Well if it's bitlocker encrypted I have some good news (potentially) Yellowkey (CVE-2026-45585) is able to bypass it.
marak830··on Anthropic installed a spyware bridge on my machine?
Of course I realise way too late I responded to the wrong thread....
marak830··on Not buying another Kindle
Oh thanks that Xteink X4 looks interesting, I'll do some research. Cheers!
