Small correction to an otherwise great explanation: SSNs are not recycled after death.

**Q20:  *Are Social Security numbers reused after a person dies?*****A:  No. We do not reassign a Social Security number (SSN) after the number holder's death. Even though we have issued over 453 million SSNs so far, and we assign about 5 and one-half million new numbers a year, the current numbering system will provide us with enough new numbers for several generations into the future with no changes in the numbering system.

Yes, but it’s a prefix and can’t be used as a word on its own.

I am a native English speaker and I know it. It’s rare though.

Same meaning as in German and apparently we borrowed it from German.

It’s a risk management strategy where you only do checks afterwards.

“Trust” means that you don’t make processes wait on passing checks before proceeding, because that would be expensive and/or slow.

“Verify” means that you have a separate process that comes through and runs checks afterwards, maybe on only some of the things you trusted, to catch issues.

It’s ideal when you have high-volume and/or low-latency processes where failures are low stakes but you still want to catch systemic issues eventually.

It’s related to the idea that “the optimal amount of fraud is non-zero”.

If you’re going to store it for a few days, then it is best to use a recipe that makes concentrate, which you then dilute before drinking. It tends to hold up better.

For the first part, I was like, yeah, that’s pretty much how all C++ GUIs work: a markup file describes the structure, a source file controls the behavior, and a special compiler generates more C++ code based on the markup file to act as glue.

That’s all pretty standard, and it’s annoying, but I didn’t really get why they were making such a big deal out of it.

Missing documentation is also annoying but not uncommon for internal widgets.

What really elevates this from simply annoying to transcendentally bad, is the lack of error messages, the undocumented requirements that resource IDs be sequential, and the mandatory IDE plugin. That’s all unforgivable.

What you are looking for is some way to shortcut the process of learning to write an operating system by re-using your existing knowledge of Python.

(I'm not judging that; I understand why you want to do it)

The simple truth is that there is no way to do that. Any solution that involves using Python in a kernel would cost you more in terms of complexity and time than learning C would.

It is rarely worth it to use a language outside of the domains that it is normally used for.

I assume that they mean that OpenCL, which is a traditional GPGPU language, is a very restrictive subset of either C or C++ (both are options) plus some annotations.

In fact, OpenCL toolchains already use the Clang frontend and the LLVM backend, so the experience of using and compiling them is very close to C++.

The talk mentions all of this; it says that a benefit of using full C++ on the GPU over using OpenCL is that you don’t have to deal with all the annoying restrictions and annotations.

I received an actual email requesting a donation from the “Harris Victory Fund” two hours ago.

Here’s the fine print from the email on where the money would go:

The first $41,300/$15,000 from a person/multicandidate committee (“PAC”) will be allocated to the DNC. The next $3,300/$5,000 from a person/PAC will be allocated to Harris for President’s Recount Account. The next $510,000/$255,000 from a person/PAC will be split equally among the Democratic state parties from these states: AK, AL, AR, AZ, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, MT, NC, ND, NE, NH, NJ, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WA, WI, WV, and WY. Any additional funds will be allocated to the DNC, subject to applicable contribution limits.

I tend to be warm when running. Around 40 F I’ll put on gloves, and around 32 F I’ll put on a light wool jacket and a beanie. I don’t run outside if it’s colder than that. I never wear long pants; my legs are always warm from the exercise.

I appreciate this. It’s a good overview of what it means to be a productive part of a larger context.

I prefer the terms “throughput” for “worker productivity” and “latency” for “work-unit productivity” but I can see why they chose to use their terms.
