Good consideration but I still think there’s an uptick. This is all AI generated as I’m not in a spot to do anything more at the moment but this is a chart of ‘linux kernel’ CVEs rated as high/critical correlated with NVD.

Hammer faces would work (def wear goggles!!!). Hit the face of the disposable one with a mixture of hydrogen peroxide, vinegar and salt and wait an hour.

I just did some analysis on this last weekend, in 2024 there were roughly 100 CVEs published every day. In April we hit approximately 200 per day.

Going backwards from 2023, the doubling interval for published CVEs was approximately 4 to 4 1/2 years. Since then it’s approximately two years.

There has definitely been a rapid uptick.

How is this post two hours old and I don't see any references to Project Farm:

https://www.youtube.com/c/projectfarm

One of the best review channels for products in this area. I moved from DeWalt to Milwaukee for most of my daily drivers about six years ago and have been very happy with them, but for things I will rarely use I tend to go with whatever Harbor Freight is selling. If I break it then it's time to upgrade.

>Do the whole "too dangerous to release" shtick.

One aspect that isn't really discussed much in this context is how to wrap one's head around the corporate risk with models of ever increasing capability. It might not be too dangerous to society, but it could be too dangerous to Anthropic.

I can’t say for certain but I’m nearly positive I’ve seen ads for this on Facebook or Insta or something like that.

New comment by jcims in "Let’s Encrypt – Stopping Issuance for Potential Incident"

jcims — Fri, 08 May 2026 23:31:58 +0000

The number one thing for me would be to standardize methods to implement soft failures. Minimally in standard clients and libraries the ability to warn when certs are nearing expiration. Cert extensions to declare lifecycle expectations and possibly even warning endpoints for notification. Basically some way to empirically look at a valid cert and know something is wrong before it fails.

There are all sorts of potential privacy/security issues with any feature built in this area so it would have to be done carefully, but I think useful improvements could easily be made.

I just find it incredible that in 30+ years the industry hasn't adapted one bit to the brittle failure modes of certificates. I did some subcontract work with Verisign to deploy their CA infrastructure back in the early oughties and it felt like a solution was overdue way back then. I was at Google in the teensies when gmail broke due to expired SMTP certs. WAAAY overdue by then. Here we are, a decade later and it's still the same lol.

Tested Amazon Linux 2023 and it doesn't appear to be vulnerable in the default configuration. Would be interested if anyone finds anything different.

This is great but as someone in infrastructure tech at a large financial, there is almost no framework for cleanly separating control from data plane operations, read vs write, anything. As of right now you have to build nearly all of that yourself.

It feels like juggling pipe bombs and I have a ton of empathy for the teams being pressured by the business to roll them out with no appreciation for the regulatory rat's nest that ensues.

They've been scaling these things up over the past decade. The JetCat P1000 can exceed 200lbs of thrust.

What they really for this kind of build are RC turbofans, which are extremely uncommon. This thing puts out over 300lbs of thrust at full throttle:

That property is gorgeous and Tyler pulls out all the stops for his builds. That channel (Ramy RC) has quite a few of them.

jcims — Sun, 03 May 2026 20:26:49 +0000

I experience the same thing very frequently. I likened it to activation energy in a reaction, that no matter what I did I couldn't create the required electrochemical bias in my brain needed to put ideas into action. It's like being stranded in your own mind, you know what you need to do, but the 'go' just never arrives.

I eventually discovered that the adrenaline response from extreme stress ('if I don't get this fucking thing done by 7:30am I'm fired' kind of thing) allows me to lock in and do the thing.

jcims — Wed, 29 Apr 2026 17:21:40 +0000

I'm shocked that you're shocked lol.

$100 for a somewhat specialized, durable medical device that has to meet regulatory standards and will be used daily, possibly for years, by healthcare providers to do patient assessments?

A 3D printed option is going to require a 3D printer, appropriate filament and should be unit tested to ensure it's within spec. The durability is going to be suspect no matter what. It's an awesome project and I'm sure would be a welcome addition to the 'boostrap humanity' catalog of 3D printed parts, but for everyday doctors plunking a hundo on a good tool is going to be a no-brainer.

New comment by jcims in "How ChatGPT serves ads"

jcims — Wed, 29 Apr 2026 02:12:08 +0000

I experimented with this way back when custom GPTs were first released (looks like late 2023). There are a few / commands you can use to suggest what product to inject, how overt, etc and a generic /operator command to send whatever you like 'out of band' from the chat.

https://chatgpt.com/g/g-juO9gDE6l-covert-advertiser

One of the most interesting things is when it starts pitching a product and you start interrogating it about why it picked that product. I haven't used it in probably a year so it may not do the same thing now, but back then it 100% lied consistently and without any speck of remorse. It was rather eye opening.

Edit: Tried again, it didn't lie this time lol - https://chatgpt.com/share/69f16aa4-c008-83ea-92b3-51f16ca77d...

I was going to use that to start a private voicemail company in my little rural town. Had the name and everything ready to go (mailvox!) but I was too broke to afford the second phone line xD.

Plus in retrospect I'm sure it would have been used almost exclusively for illicit purposes. But that wasn't really something I had thought of back then.

Anyone in here work at Wiz? Seem like they do pretty good work. Tool itself has survived extreme growth/feature bloat and still does pretty well. Security team has found some really cool stuff.

The motion system constrains the problem quite a bit. This video of high speed vision/actuators is 16 years old - https://www.youtube.com/watch?v=bfdHY26E2jc

I was expecting/hoping for a humanoid robot.
