I have a 1.5GHz TDS7154B in addition to my 200MHz SDS1204 specifically to measure power rail noise with a low noise probe. You just can’t characterise power rail noise well with less than 500MHz of bandwidth.

I recently did something similar with a TDS7154B. Rather than going with an IDE/PATA drive I was able to use the SATA Gen1 ports on the motherboard and a molex-sata power adapter to use a modern SSD.

The government loan changes the calculus. Allows for short term thinking and a long term benefit.

It feels like LEGO for a while have been dumbing-down their education products. I saw it with computer science education as a whole during my schooling. Instead of focusing on fundamentals there was more and more layers of abstraction added

You buy the physical rack and install it in your data centre. It is your property.

$1k per year if you run an action 24/7. How many minutes per month do you actually use? How does that compare to the cost of the machines being used as runners? The real mistake was GH not charging anything for self-hosted runners in t

Is there a technical reason it only supports x86_64, riscv64, and not arm64?

Yes, but you aren't wasting time early on negotiating compensation.

Have a look at Ethercat. Based on the same physical layer as Ethernet but allows daisy-chaining devices.

Trying to secure hardware that the attacker has direct access to is just so brutal. Your hardware vendor can promise compliance with X spec, implement Y protections and still fall foul to something like this.

It’s interesting to me that every robotics framework essentially boils down to a specialised pub-sub system with some flavour of serialisation and some kind of startup/launcher to wrangle running separate processes. Props to this team

Importantly for RP2040 users, RTIC 2.0.0 is currently single-core only. I’m using RTIC for the firmware on my STM32H7 based product ( https://umi.engineering ) and it has been a joy.

Nice looking landing page. Small bug, when I scroll down the page and then click "pricing" it doesn't take me to the right spot on the page until I click again. On Firefox 125.0.3

I wonder what the smallest circular OLED display is. There are 01005 LEDs (the next size down from the 0201's used here) but at that point an OLED display is essentially the same thing.

The Terraform provider[1] unfortunately is 3rd party and as such doesn't bring and guarantees of correctness other than that of the maintainer. It would be nice to see Keycloak provide an official solution for configuration management

Stop putting solar panels on cars. It’s just not worth the cost or complexity. That square meter of PV is going to get you at most 250W in perfect conditions. Conditions that aren’t found in cities or even at ground level in residential are

I welcome your sympathy because Azure constantly makes my life hell. So many half baked features and legitimate bugs in their platform that they either don’t fix or take years to fix.

Most often I’m using ‘cordon’ and then ‘drain’ to remove nodes from a cluster that has auto-scaled up, but is being hesitant to scale down. Pretty nuts to think I’ve saved six figures in VM costs just doing that once or so a month.

I don't have any data to back this up, but I would argue that the alcoholism is more cultural and circumstantial than causal.

Interesting is how this applies to interpolation with industrial robotic arms. Shortest path for each joint moving from a -> b does not create a linear path for the end-effector of the robot. Linear end-effector movements require inverse

Only for the cases you are set up to test. This is about headroom on your golden resources so any kind of overload you can buy yourself time for.
