I believe this underestimates the difficulty of such an attack and the value of training. This isn't deer hunting where little to nothing is at stake. It's a homicidal attack in the midst of an urban area, with armed law enforce

It's incredibly accurate as most such events go, with the grade of shooters and weapons typically seen. It's not terribly remarkable for a trained shooter with a good rifle. A 1 MOA or better rifle with a reasonable optic makes

I've listened Keller's views on CPU design and the biggest takeaway I found is that performance is overwhelmingly dominated by predictors. Good predictors mitigate memory latency and keep pipelines full. Bad predictors stall eve

An obvious use case is high-end NVRs. Low power, ample GPU for object detection/tracking, ample encoders for streaming. Should make a good surveillance platform. With SR-IOV* there is a low cost path for GPU in virtual machines. Unt

Because I'm not a CPU engineer, and neither are you. Neither of us can claim anything about fucking around with CPU clocks and voltages or anything else about any of this. If you want to screw around in BIOS settings and learn where

I do. I've been buying Intel for the same reason as the author: I build machines that don't have glitches and mysterious failures and driver issues and all the rest of the garbage one sees PC assemblers inflict on themselves. Ma

The history behind TAT-1, the first transatlantic telephone cable, and the repeaters used, is fascinating. Bell Labs designed the repeaters. The repeaters used vacuum tubes for amplification and were designed for extreme reliability. The

I'd explain your cases this way: C# has a dictator with a budget: Microsoft integrated async into C# in a formal way, with 5.0, including standard libs, debugging, docs, samples, clear guidance going forward, etc. What holes there wer

That may change. There are some very powerful MCUs appearing, with astonishing features, including hardware virtualization (hypervisors on an MCU,) multicore superscalar, heterogeneous CPU cores with high performance context switching, &qu

People without a background in electronics don't appreciate what modern CPUs and GPUs are doing: the amount of current flowing through these devices is just mind blowing. With adequate cooling, a Ryzen 9 9950X is handling somewhere in

As there is ongoing drama with Zen 5 and power issues, there are people with the instruments and the motivation to investigate this. You should consider contacting Gamers Nexus, and help them to get your test suite running. They can meas

> the paid edition now locks you in a yearly subscription Good to know and damn, that sucks. I'm still on 8, and I've felt zero need to move on, so I didn't know they'd done that.

No: the ditch company had the easement and the right to deal with their ditch and its problems. They dealt with me fairly and covered all the costs: I feel pretty fortunate that no serious damage to my or other peoples property occurred.

I use to live on a property in a development. On my property were a pair of big willows. The trees were large and healthy, well over 50' tall. That was strange, because the region is high desert with little water, and I made no effo

I use to license Acronis as well and I share your view of the software quality. Since then I moved on to Macrium Reflect: better UI, faster, fewer glitches. It paid off about 9 months ago when a 1TB 970 Pro NVMe failed. Flawlessly restor

One way to know is to see if new tape products exist, indicating ongoing development. As of May, 2025, LTO-10 is available, offering 30TB/75TB (raw/compressed) storage per cartridge. Street price is a bit under $300 each. Two m

Few people are paying those prices. Cell providers sell these at far less: on the order of 60% of Googles retail price.

Good question, and yes, I did. RMT can work, but ACT has a key advantage. Motion curves are naturally segmented into phases. With ACT, the Repeat Count Register (RCR) defines how many cycles to hold a given frequency and duty, so each phase

From the blog: "Not surprising once you understand that slewing to a target significantly increases the number of pulses per second sent to the motors, and everything became just too much to handle for our little ESP32." A hobby a

How feasible is this for a cloud operation(s)? I imagine this work requires close collaboration with the architects and proprietary knowledge about the design.

I'm using AWS for small k8s clusters. I stay away from most of the "managed" AWS products except S3 and ECR. My k8s stack is packer + tofu + k3s + zfs: It's easy, concise, self managed, and costs are easy to predict.

It does, for M.2, which is really great: much better than an SD card. I was writing generally about the comments I see about these types of low cost boards: we are awash in these products, which is a good thing, but many are not designed wi
